Opis:
This theoretical article presents a case for a new approach to the teaching of word recognition in English as a foreign language to young learners in Polish early years education, arguing that there is a need for greater attention to explicit instruction in alphabetic principles, selected phonics and decoding skills. Research in first language (L1) English and foreign language (L2) development of word recognition skills is outlined. Differences between the orthographies of Polish and English are highlighted. Approaches used in L1 early reading instruction are contrasted with those commonly applied in L2 settings. The need for more explicit instruction is rationalized on the basis of a brief description of impressions from 20 hours of classroom observation. The second part of the paper presents some principles for the design of materials to introduce alphabetic principles of English and elements of phonics to support word recognition, with examples. The ability to recognize words rapidly and with ease is a key skill, which, unless mastered early, could potentially have a negative impact on the whole of a child’s language education.

Opis:
The article examines the possibilities of fostering young L2 learner print awareness via teaching for conversing about and reflecting on writing. In order to achieve this goal the present author conducted the qualitative research on a group of 2nd-graders engaged in the performance of a series of open-ended L2 written tasks accompanied by L1 cues. The analysis of collected data shows that drawing children’s conscious attention to writing might encourage the constructive transferability of linguistic skills from L1 to L2, thus being conducive to the development of logical thinking necessary for the enhancement of their print awareness.

Opis:
This scoping review explores the causal relationship between morphological instruction and reading development in young L2 learners by synthesizing 12 primary studies published between 2004 and 2019 (N = 1,535). These studies focused on reading English as the target language and involved participants between kindergarten and Grade 12 from four countries (China, Egypt, Singapore, and the USA). Findings suggested that (a) morphological instruction led to consistent and positive gains in L2 children’s morphological awareness and vocabulary knowledge, and the effect sizes (Cohen’s ds) ranged from small to large; and (b) the relationship between morphological instruction and other outcomes such as phonological awareness, word reading accuracy, word reading fluency, spelling, and reading comprehension was inconclusive. Notably, transfer effects of L2 English morphological instruction on novel word learning in English or on reading development in an additional language were only examined and observed in four primary studies. Discussion was provided regarding future instructional and research design.

The aims of the study were to identify the fungi associated with the decay of thin roots (1-5 mm) of 1, 3 and 15-year-old Fraxinus excelsior plants and to estimate the pathogenicity of certain fungi. In total, 400 fungal isolations were performed from which 334 cultures were obtained. Altogether, 26 species of fungi were identified. The following species were most frequently obtained, independently of plant age and origin: Alternaria alternata, Chaetomium globosum, Cryptosporiopsis sp., Fusarium oxysporum, F. solani and Cylindrocarpon destructans. The last three of these were then used in an inoculation test. F. oxysporum caused the death of over 80% of 2-month-old seedlings grown in boxes containing perlite and kept in a growth chamber.

Opis:
Phytochemicals, proximate, minerals and anti-nutrient compositions of young cocoyam (Colocasia esculenta) leaves were determined using standard methods. Qualitative and quantitative analyses for phytochemicals confirmed the presence of bioactive constituents such as alkaloids, flavonoids and saponins in appreciable amounts, while terpenes, cardiac glycocides and tannins were only present in trace concentrations. Mineral analysis revealed that K recorded the highest content - with 214.00 ± 2.11 mg/100g, followed by Ca - 157.10 ± 1.47 mg/100g, Mg - 63.00 ± 0.58 mg/100g, P - 32.00 ± 0.61 mg/100g, while Fe had the lowest value - 0.10 ± 0.14 mg/100g. Proximate composition analysis of C. esculenta leaves indicated that CHO, protein and crude fibre were present in high quantities (35.22, 17.10 and 16.41 % respectively), while fat was at the lowest content (8.82%). Anti-nutritional factor analysis of young leaves of C. esculenta indicated that phytates was present in huge quantity - 11.03 ± 0.12mg/g, followed by oxalates - 7.62 ± 0.14 mg/g, while tannins recorded the lowest anti-nutritional contents - 0.12 ± 0.06 mg/g. This study has also revealed that the young leaves of C. esculenta contain appreciable levels of bioactive components (phytochemicals such as as alkaloids, flavonoids and saponins; minerals K, Ca, Mg, P and Fe) and appreciable amounts of CHO, protein and crude fibre. The results of anti-nutrients analysis showed high contents of phytate and oxalate. The last is probably responsible for the itching effect and also interferes with the utilization of essential nutrients. Thus, young leaves of C. esculenta provide appreciable quantities of nutrients and thus can rival other conventional vegetables normally consumed in Nigeria.

Opis:
The effects of drought stress, stress by increased nitrogen depositions and the combined effect of the two stress factors on the growth of Norway spruce Picea abies (L.) Karst. were studied in two stands. The drought stress was induced by reducing atmospheric precipitations by 60% and the increased nitrogen depositions were simulated by repeated applications of ammonium sulphate at a rate corresponding to 100 kg N ha–1 year–1. All stress factors under study affected the height increment of the above-ground part, the length and colour of needles, and the biomass, vertical distribution, functionality and mycorrhizal infection of fine roots. The root system responded to the simulated stresses right from the the very first year of their action, exhibiting a greater damage than the above-ground part of the plant. Drought acted as a stress factor stronger than the nitrogen depositions themselves. The strongest impact was recorded in the simultaneous influence of the stress factors.

Opis:
In the Kolbuszowa Plateau forest areas, aggregations of brambles were observed most often in young forest plantations and forest clear cuts. In the 20 plantations that we examined, 11 bramble species were found. The most common bramble species in young forest plantations were Rubus plicatus, R. nessensis, R. hirtus, R. idaeus and more rarely R. gracilis, R. ambrosius and R. apricus. The largest bramble aggregations occurred in plantations located in mixed pine-oak forests, subcontinental lime-oakhornbeam forests and drained black alder forests. In young forest plantations the Rubus species were accompanied by species characteristic for the Vaccinio-Piceetea, Querco-Fagetea, Epilobietea angustifolii, Molinio-Arrhenatheretea and Nardo-Callunetea associations. There are three groups of bramble species which occur in young forest plantations: I – species with thin, prostrate and rooting stems (R. hirtus, R. apricus, R. pedemontanus), the negative impact of which on tree seedlings could have been very significant if the bramble specimens or diaspores had been present at the moment of tree planting; II – species with strong, poorly branched and arched stems (R. plicatus, R. gracilis, R. ambrosius, R. glivicensis), which negative influence on tree seedlings depends on the capability of the species to produce a big, dense bush in a short period of time thereby increasing shade; III – species with erect and relatively sparsely growing stems (R. idaeus), which are not a threat for the young forest plantations. Species with intermediate features (e.g. R. nessensis) may have a negative impact on young plantations generating a large, dense aggregation, however in most cases their populations only grow sparsely and do not hinder the growth of tree seedlings.

In the paper the density, height, diameter, slenderness and vitality of the 17 year−old pine young−growth stands depending on the basal area of the shelterwood (four thinning variants: G1−G4). The studies were carried out in eleven 70−90 year−old pine stands heavily damaged in the 80s of the past century by the nun moth (Lymantria monacha L.). With the development of the overstorey the growth, the vitality and the stability of young stands declined. In addition, a decrease in the survival of the young−growth stands under the dense canopy (variant G4) was recorded. A long−term maintenance of young stands under the shelter of the canopy in the areas of low annual precipitation (below 600 mm) requires the reduction of the dbh basal area to the level of at least 15 m3/ha before attaining the age of 15 years.

Opis:
Mineral nutrition of apricot is very specific and depends on different factors such as soil fertility, soil pH, weather conditions, cultivars, rootstocks, fertilizers, age of trees etc. For these reasons, during 2008 and 2009 we evaluate nutrient status of five apricot cultivars (Vera, Aleksandar, Biljana, Harcot, Roxana) at 120 days after full bloom (DAFB) grown on acidic soil in the region of ýaþak (Western Serbia). The results showed no statistically significant variations in the N, K and Ca content of apricot leaves among cultivars, as opposed to significant differences in the content of P, Mg, Fe, Mn, Cu, Zn and B. The ȈDOP index revealed that the average content of all macro- and micronutrients was below the optimum, except that of P in both years and that of Mn and Cu in the first year of the study. The insufficient nutrient supply of the test apricot cultivars requires adjustment of fertiliser types and application rates to this soil type according to foliar analysis.
Odżywianie mineralne moreli jest bardzo specyficzne i zależy od różnych czynników, takich jak: żyzność gleby, pH gleby, warunki pogodowe, odmiany, kłącza, nawozy, wiek drzew, itp. Z tych powodów, w latach 2008 i 2009 oceniamy poziom odżywienia pięciu odmian moreli (Vera, Aleksandar, Biljana, Harcot, Roxana) w 120 dni po pełni kwitnienia (DAFB), hodowanych na glebie kwaśnej w regionie ýaþak (Serbia Zachodnia). Wyniki nie wykazywały statystycznie istotnych odchyleń w zawartości N, K i Ca w liściach moreli różnych odmian, w przeciwieństwie do znaczących różnic w zawartości P, Mg, Fe, Mn, Cu, Zn i B. Wskaźnik ȈDOP wykazał, że średnia zawartość wszystkich makro- i mikroskładników odżywczych była poniżej optymalnej, oprócz P w obu latach oraz Mn i Cu w pierwszym roku badań. Niedostateczne zaopatrzenie w składniki odżywcze testowych odmian moreli wymaga dostosowania typów nawozów i zastosowanych dawek do typu gleby, zgodnie z analizą liści.

Opis:
Biostimulants offer a novel approach for the regulation of crucial physiological processes in plants. Recently, it has been observed that the application of biostimulants on both seeds and plants may ameliorate to some extent the negative effects of abiotic stresses such as drought, heat, salinity, and others. In the climate conditions of Bulgaria, the early developmental stages of warm climate crops, like maize, often occur under suboptimal temperatures. Although the mitigation of abiotic stress is perhaps the most frequently cited benefit of biostimulant formulations, little is known about their influence on chilling-stressed plants. The aim of our study was to evaluate the effects of a biostimulant from the group of protein hydrolysates on both the growth and the photosynthetic performance of chilling-exposed young maize plants grown in controlled environment. Here, we report that application of a protein hydrolysate increased the performance of chilled maize plants, as demonstrated by leaf gas exchange, photosynthetic pigment content, and chlorophyll fluorescence, but did not affect their growth. Nevertheless, based on the better preserved photosynthetic performance of the biostimulant-treated maize plants exposed to chilling, we assume that under subsequent favorable conditions their growth would recover more quickly as compared to the untreated ones.
Zastosowanie biostymulantów jest nowatorskim sposobem regulacji procesów fizjologicznych w roślinach. W ostatnich latach dowiedziono również, że ich aplikacja, zarówno na nasiona jak i części wegetatywne może w pewnym zakresie niwelować negatywne skutki stresów abiotycznych, między innymi suszy, zasolenia czy zbyt wysokiej temperatury. W warunkach klimatycznych Bułgarii wczesne fazy rozwoju roślin uprawnych pochodzących z cieplejszych stref klimatycznych, na przykład kukurydzy, odbywają się w okresach panowania temperatur suboptymalnych. Mimo, że łagodzenie negatywnych skutków stresu jest jednym z najczęściej podawanych korzystnych efektów działania biostymulantów, wiedza na temat ich wpływu na rośliny poddane stresowi chłodu jest wciąż niewystarczająca. Celem badań była ocena działania biostymulantów z grupy hydroli- zatów białkowych na wzrost i przebieg procesu fotosyntezy kukurydzy uprawianej w warunkach obniżonej temperatury. Aplikacja hydrolizatów białkowych miała pozytywny wpływ na wymianę gazową, zawartość barwników fotosyntetycznych i sprawność aparatu fotosyntetycznego mierzoną parametrami fluorescencji chlorofilu a, ale nie wpłynęła na wzrost roślin. Na podstawie uzyska -nych wyników można przypuszczać, że ze względu na sprawniejszy przebieg procesu fotosyntezy, rośliny kukurydzy poddane działaniu zbyt niskiej temperatury we wczesnych etapach rozwoju i potraktowane biostymulantami będą rosły lepiej po ustąpieniu suboptymalnych temperatur w porównaniu z roślinami nie poddanymi działaniu biostymulantów.

Opis:
Root−feeding insects are an increasingly studied group of herbivores, whose impact on plant productivity and are some of the most damaging forest pests in Europe. Due to the mass feeding on the roots of seedlings and older trees in young plantation and stands, Melolonthinae larvae are classified as pests, which are the most dangerous on the land dedicated to afforestation. The research was located in the Wyszków Forest District (52°43'15' N; 21°39'03' E) on the mixed coniferous and mixed deciduous forest habitats. This study evaluated sawdust traps as the method for assessing abundance of Melolonthinae larvae in Scots pine plantations established artificially from open nursery, container production, and from natural regeneration. In spring 2015 i) ‘small sawdust pits’ in rows between seedlings, and ii) pits without soil in adjacent inter−rows as control were prepared. In spring and autumn 2016, and in spring 2017 sawdust and soil from both variants of pits were sieved and Melolonthinae larvae were counted and compared. The obtained results were analyzed in two ways. The first analysis compared the occurrence of grubs in small pits with or without sawdust, while the other one analysed influence of the time of making small pits, independently for the variant with or without sawdust. The final stage was to compare the number of Melolonthinae larvae in small pits between the origin of the seedlings. We found a greater number of grubs in spring assessment than in autumn. Both kinds of small pits showed higher number of Melolonthinae larvae when compared to traditional method of ‘great pits’. The number of Melolonthinae larvae was significantly higher on the plots with container seedlings than the others. The conceptual assumptions of this alternative and environmentally safe method of ‘sawdust traps’ seems to be optimistic.

Opis:
In this qualitative study the author focuses on age effects on young learners’ L2 development by comparing the L2 learning processes of six young learners in an instructed setting: three who had started learning English as L2 at age 6/7 and three who had started at age 9/10. Both earlier and later young beginners were followed for three years (during their second, third and fourth year of learning English). The participants’ L2 development was measured through their oral output elicited by a two-part speaking task administered each year. Results of the analyses are interpreted taking into account each learners’ individual characteristics (learning ability, attitudes and motivation, self-concept) and the characteristics of the context in which they were learning their L2 (attitudes of school staff and parents to early L2 learning, home support, in-class and out-of-class exposure to L2, socio-economic status). The findings show that earlier and later young beginners follow different trajectories in their L2 learning, which reflects different interactions which age enters into with the other variables.

Opis:
The aim of this work was to evaluate the occurrence and harmfulness of Brachyderes incanus to young Scots pine (Pinus sylvestris L.) plantations on forest areas burned during the forest fire in 1992. The development of B. incanus outbreak had place 4 to 5 years after fire and was connected with the diminishing of macronutrients content in soil. The population of B. incanus is characterised by fast increasing or decreasing the number of individuals. During two years (two generations), the number of beetles increased from 1−2 individuals/tree (at one observation) to 50−80 individuals/tree. Also during two years, the number of beetles diminished to very low level (lower than one individual/tree at one observation). The outbreak of B. incanus in the mentioned above forest areas had place in 1999−2001.

Opis:
Teleosauridae was a group of largely marine Mesozoic crocodylomorphs, typically considered as akin to "marine gavi-als" due to their elongate, tubular, polydont rostra that are indicative of a piscivorous diet. Here we show that these extinct crocodylomorphs were more anatomically, and perhaps ecologically, varied than previously thought. We report the first evidence of denticles in a teleosaurid tooth, revealed by scanning electron microscopic (SEM) analysis of a tooth from the holotype of "Steneosaurus" obtusidens. These denticles are cryptic, because they are microscopic, not contiguous along the carinae (instead forming short series), and are detectable only using SEM. This incipient denticle morphology is similar to that recently discovered in a closely related group of marine crocodylomorphs, the Metriorhynchidae. In particular, the denticulation morphology of "Steneosaurus" is similar to that of the geosaurin metriorhynchid Torvo-neustes, indicating that these two taxa may have employed similar feeding styles and that "S."obtusidens may have been a nearshore ecological analogue to the more offshore, fast-swimming geosaurins. Previous authors have considered "S." obtusidens andMachimosaurus to be durophagous, but the discovery of denticulated teeth indicates that they had a more varied diet and feeding style, and included flesh slicing as part of their feeding toolkit. It is currently unknown how extensive denticulate carinae may be in Teleosauridae, and we hypothesise that cryptic denticles may also be present in other marine crocodylomorphs once they are subjected to SEM study.

Opis:
Motivation has been widely considered one of the most influential variables in the field of second language learning. Motivation may vary throughout the years, even within the duration of a single language class, and this might occur due to different factors, such as the choice of tasks or the activity type (i.e., collaborative or individual). These two factors have not been investigated in depth with young learners in foreign language settings, and from a task-based perspective. Thus, this paper addresses this gap, and explores the potential changes in motivation of 64 Spanish young learners of English as a foreign language who worked on a number of dictogloss tasks in pairs and individually over the span of a school year. Data was collected several times by means of different tools that measured students’ general and more specific task motivation, as well as their attitudes towards individual/pair work. The findings revealed that, overall, these children’s motivation was high and consolidated with time, while their level of anxiety decreased. Their attitudes towards the dictogloss were positive from the beginning to the end of the school year, and more so when they carried out the task in pairs. These findings support the benefits of collaborative work, and the dictogloss, as an appropriate task that engages children in their learning of a foreign language.

Opis:
The paper outlines the publishing history of Henryk Sienkiewicz’s Quo Vadis in Italian editions for children and young adults in the 20th century. The research conducted so far has shown that Sienkiewicz’s novel was part of Italian publications for a young readership as early as at the beginning of the 20th century, and that the book was frequently republished and reedited by numerous publishing houses over the following decades. The paper aims to present the strategies applied by Italian publishers as they recast Sienkiewicz’s work into versions specifically targeting young readers. Sienkiewicz’s Roman narrative proved a source of easy revenue for many publishing houses. Discreditable translatory practices were, at least at the beginning of the 20th century, mainly the domain of Milanese publishers whose efforts also focused on reworkings of Quo Vadis for children and young adults after the Second World War. The paper discusses examples that vividly illustrate the commercialisation of literature and publishers’ responses to the changes of the Italian publishing market in the second half of the 20th century. The findings of a study that used quantitative methods to analyse the corpus of 18 Italian editions of Quo Vadis are presented as well.
L’articolo abbozza la storia delle edizioni italiane per ragazzi e adolescenti di Quo vadis di Henryk Sienkiewicz nel XX secolo. Sulla base delle ricerche finora svolte, è stato accertato che l’opera di Sienkiewicz comparve nell’offerta editoriale italiana rivolta ai giovani lettori già dall’inizio del Novecento, e poi per molti decenni fu volentieri riproposta da numerose case editrici. L’obiettivo dell’articolo è quello di indicare le strategie degli editori italiani che, pensando ai giovani lettori, portarono alla realizzazione di nuove versioni dell’opera di Sienkiewicz. La trama romana del romanzo di Sienkiewicz si rivelò una fonte di facile guadagno per molte case editrici e in ambito di pratiche traduttive ingloriose si distinsero, almeno all’inizio del Novecento, gli editori milanesi, offrendo, soprattutto dopo la Seconda guerra mondiale, anche rifacimenti e riadattamenti di Quo vadis per il giovane pubblico. Gli esempi riportati nel testo illustrano anche il processo di commercializzazione della letteratura e le risposte degli editori all’evoluzione del mercato editoriale italiano nella seconda metà del XX secolo. L’articolo presenta anche i risultati della ricerca sul corpus di 18 edizioni italiane di Quo vadis con l’applicazione dei metodi quantitativi selezionati.

Opis:
Patterns of nutrinal behaviour that are shaped in childhood and during adolescence are mostly continued later on in adult life. The risk of developing many chronic diseases is to a large degree dependent on these patterns. The aim of this study was to assess the relationship between dietary habits and body image perception among Polish adolescents and young adults. The study group covered 14,511 adolescents/young adults: 10,081 children attending high schools and secondary schools and 4,428 university students. More than 87% of school children and students admitted that they snacked in between meals everyday, and 1/3 mentioned that they ate meals at night. As many as 41.40% of schoolchildren and 46.70% of students experienced the feeling of overeating at least several times a week. Analysis of the respondents BMI showed that students were considerably more obese and overweight compared to schoolchildren. Fear of gaining weight was mentioned by 9.90% of respondents including 6.90% of those with normal body structure, 1.40% with underweight or overweight and 0.40% of those obese. As many as 54% of the total respondents described their body structure as being normal, 23.7% as slim, 13.9% reported being overweight, 6% thin whilst 1.7% considered themselves obese. A comprehensive analysis of the study data, including attempts at dieting or gaining weight, indicated that approximately ¾ of obese respondents had undertaken attempts in the past to reduce their body weight. The importance of physical activity and healthy eating habits should be given due attention not only to prevent obesity but also other eating disorders.

Opis:
Two of the best known Mesozoic marine reptile assemblages can be found in units deposited in the Jurassic SubBoreal Seaway of the UK: the late Middle Jurassic Oxford Clay Formation (OCF) and Late Jurassic Kimmeridge Clay Formation (KCF). They record two very differently structured faunas, but understanding the turnover between them is hampered by a gap in the fossil record that spans much of the Oxfordian, the so-called “Corallian gap”. We provide a comprehensive review of specimens from the Corallian Group (CG) of the UK, which includes the first descriptions of several fossils, particularly teeth. We demonstrate that there is a severe reduction in observed marine reptile diversity during the Oxfordian, with several Callovian taxa well known from the OCF not persisting into the Corallian strata, including small-to-mid-sized pliosaurids and longirostrine teleosaurids. We do, however, find evidence that at least one member of each key OCF lineage (plesiosauroids, pliosaurids, ichthyosaurs, and thalattosuchians) survived into the Corallian interval, and that one keystone KCF lineage (the Torvoneustes line of metriorhynchid thalattosuchians) was present during this time, indicating an earlier radiation of this group than previously thought. We suggest that faunal turnover between the OCF and KCF may have been driven by environmental perturbations during the Oxfordian, which selectively removed small bodied pliosaurids and longirostrine teleosaurids from the Jurassic Sub-Boreal Seaway, but less affected metriorhynchids, plesiosauroids, and ophthalmosaurid ichthyosaurs. The preferential removal of taxa from the sub-Boreal realm may have helped facilitate the radiation of lineages that became dominant during the Late Jurassic.

Opis:
From the beginning of the emergence of organised forms of opposition in the second half of the 1970’s the young people actively engaged in their activities. In this period, the first independent youth organisations represented by Student Solidarity Committees (SKS) and the Movement of the Young Poland (RMP) were formed very quickly. Along with those structures the first press titles authorised by these environments appeared. After the strikes of August 1980 and the creation of the NSZZ "Solidarity" the youth activated publishing of the independent public press. It bloomed, however, just after the introduction of the martial law in December. The present article presents, in a concise manner, the development of the phenomenon of the youth’s independent publishers in the years 1977 -1990.

Introduction and objective. Bioimpedance analysis (BIA) phase angle (PhA) is an index of the integrity of cells and cellular membranes. The aim of the study was identification of behavioural and anthropometric predictors of PhA in a group of young adults. Materials and method. A cross-sectional observational study of health behaviours, anthropometric indicators and body composition assessed by the BIA method was conducted in a group of Polish young adults (n=92) aged 18 – 24 (mean – 19.33, STD – 0.915). Behavioural variables included: level of physical activity, eating behaviours and nutritional knowledge. Body composition was analysed by means of BIA phase-sensitive 8-electrode medical SECA mBCA 525 device. Results. The mean PhA value in the examined cohort was 6.38±0.75 (males – 7.22±0.72; females – 6.13±0.57). Males also showed higher statistically significant other body composition indices, excluding fat mass. The multiple regression model, including anthropometric variables and gender, which explained the effect of these variables on PhA, occurred to be significant (p<0.0000) and allowed explanation of the 82.49% of PhA variability. PhA was significantly predicted from body mass index (BMI), absolute fat mass, visceral adipose tissue value, skeletal muscle mass value and gender. The regression model, including behavioural predictors and gender, allowed explanation of the lower percentage of PhA variability (42.75%; p<0.0000) and included general intensity of health behaviours, level of nutritional knowledge, and gender. A regression model which would consider simultaneously anthropometric and behavioural variables could not be constructed. Conclusions. In the examined cohort, anthropometric and body composition variables showed a stronger predictive value with respect to PhA, compared to behavioural variables.

Introduction. Insulin resistance is becoming an increasingly widespread problem worldwide. For its determination indirect indices of insulin resistance or insulin sensitivity have used. Those indices based on simultaneous measurements of blood glucose and insulin concentrations under fasting conditions or during the Oral Glucose Tolerance Test. Objective. The aim of the study was to estimate reliable reference values for the indices used in insulin resistance diagnosis. Materials and method. 191 selected participants, aged 18–31, were enrolled into the reference population. 130 participants from the reference population with fasting glucose ≤5.5 mmol/L, BMI<25 kg/m2, and without metabolic syndrome, were finally included in the reference group. The following insulin resistance indices were calculated: HOMA1-IR, HOMA2, HOMA2 from C-peptide, QUICKI, Matsuda Index and Insulin Secretion-Sensitive Index-2. Determination of reference intervals for indirect indices of insulin resistance was conducted in accordance with the C28-A3 procedure recommended by the Clinical & Laboratory Standards Institute (CLSI). Results. The reference intervals for indirect insulin resistance indices examined according to CLSI protocol were: ≤4.00, ≤2.27, ≤4.10, ≥0.31 for HOMA1-IR, HOMA2, HOMA2 C-pep., and QUICKI, respectively. For insulin sensitivity, the value of the Matsuda Index was established as ≥3.19 and for beta cell pancreatic function ISSI-2 as ≥206. Conclusions. Establishing a reference intervals for these indices enable the proper identification and differentiation of the types of insulin resistance in particular populations. The early detection of metabolic disorders allows for introduction of effective preventive action.

Experimental results of investigation a new fiber-optic phase demodulator operating in the Young interferometer configuration are the main subject of this paper. The experimental set-up contains set of two single mode optical fibers with collimators and rectangular prism for protecting the coherent beams coupling. Next a lens has been used for the optical Fourier transform realization. In this way, a spectral power density in Fourier back focal plane is spatial modulated, with frequency depended among other things on distance between fibers. The proper spatial integration of the output filed, for instance by using the two elements photodetector, the unambiguous information about phase changes in the range from 0 to 2π can be obtained by proper signal processing. The paper presents the experimental results which are in good agreements with theoretical model. Because the CCD element has been used in the presented experiment, the detected plane has been divided on two parts by special numerical procedure. Finally, the application commercially available multi-elements photodetector will protect above procedure in a hardware way.

This paper presents the use of new technical equipment by young adults (30 years old or younger), and the physical symptoms they have. The paper then analyses how the symptoms are associated with the use of computers and mobile phones, taking into account the background information. The study is based on a survey of 15 000 working-age (18–65) Finns. The responses (1563) covering young adults’ physical symptoms were analysed. Altogether 53.3% of all young adults had pretty often or more frequently pain, numbness or aches in the neck and 32.2% had aches in the hip and lower back. Women experienced more pain, numbness or aches in the neck (65.0%) than men (34.5%). The use of different computers at leisure quite often had an association with some symptoms in different parts of the body. In addition, exhaustion at work had associations with some physical symptoms. In the future, it is essential to note ergonomic reasons and exhaustion at work when young adults experience pain, numbness or aches.

Opis:
The article regards the religious identity of young people in the modern Ukrainian society. The qualitative analysis is based on the written students' autobiographies collected in various regions of the country. As a result of the texts interpretation, there were defined the following three types of religious identity among young people: deep, critical and situative-affiliative. Each of them has its own mixture of subjective and objective factors in construction of religious identity (intentions for choice, critical or uncritical perception of institutional religious behavior, biographical aspects that often push people to become religious).

Opis:
Silicon nitride powder with a small addition of magnesium oxide and yttria stabilized tetragonal zirconia fine particles was used as a starting material. Multilayer graphene nanoplatelets were used as filler for silicon nitride based composites. Graphene content in the mixtures was 0‒2 wt. %. The composites were obtained by the Spark Plasma Sintering method at 1650°C under 35 MPa of uniaxial pressure. Separation of the agglomerated graphene platelets in the matrix was observed for these materials. Insufficient dispersity of graphene slightly decreased the mechanical properties of Si3N4 ceramics. The SEM and TEM microstructural analysis of sintered materials show that the applied pressure during the sintering process leads to the orientation of the graphene phase and in consequence causes anisotropy of properties. The differences of friction coefficients were examined with the Ball-on-Disc method for the two directions (parallel and perpendicular to the pressing axis). Also the specific wear rate of the ball for the direction parallel to pressing axis differ significantly in comparison to the wear for the direction perpendicular to the pressing direction.

The study presents the results of investigation on reaction of beech (Fagus sylvatica L.) leaves observed next year after planting seedlings in different positions in a young spruce stand located in upper mountain conditions. The methods of chemical analyses and assessments of chlorophyll fluorescence were applied with the aim to evaluate a course of leaf adaptation. In the young spruce stand located in the Karkonoše Mts, bare root beech seedlings after cultivation in full light were planted into three main positions to spruce trees (under the crown, within crown perimeter and in stand gaps). Next year after planting, the total biomass, leaf nutrient content and chlorophyll fluorescence parameters were evaluated. The beech trees planted under spruce (Picea sp.) crowns had significantly lower specific leaf mass and the mean leaf area was decreasing from shade to sun. Differences in nutrient contents were not significant between the treatments. We found significantly higher values of minimal (F0) and the maximum fluorescence (Fm) as well as of the maximum quantum yield of PSII photochemistry (Fv/Fm) in the leaves of beeches growing under the spruce crown. Significant differences among treatments were found also in the courses of the values of maximum fluorescence yield Y(II) and nonphotochemical quenching (NPQ). Our study indicated that bud forming processes are only partially responsible for physiological properties of beech leaves evaluated next year after planting. Photosynthetic performance is also influenced by actual growing conditions. A great part of acclimation occurs already in the first year after planting (change of the light conditions). We speculate that this phase of gradual acclimation of the assimilation apparatus can be one of the reasons of physiological weakening of the plant after planting to different light environment.

Opis:
Research has shown that learners of different linguistic backgrounds make similar errors, which is due to linguistic transfer. Cross-linguistic similarities between L1 and L2 can result in: positive transfer, negative transfer, and differing lengths of acquisition. The bigger the difference between the languages, the bigger Second Language Acquisition difficulties and more numerous potential negative transfer areas. This effect is visible in the case of Polish as L1 and English as L2. English and Polish differ in terms of pronunciation (e.g. vowel-based vs. consonant-based), spelling (e.g. opaque vs. semi-transparent), grammar (e.g. fixed vs. flexible word order), syntax (e.g. analytic vs. synthetic), and vocabulary. Therefore, second language instruction should include the errors caused by linguistic transfer, which would facilitate the selection and development of effective instruction methods and techniques.68-76

Opis:
The alarming problem of a decline in physical activity among children and adolescents and its detrimental effects on public health has been well recognised worldwide. Low physical activity is responsible for 6% of deaths worldwide and 5-10% of deaths in the countries of the WHO European Region, according to country. Within the last decade, many initiatives have been launched to counteract this phenomenon. The objective of presented study was analysis of the level of physical activity among adolescents and young adults in Poland, according to the IPAQ questionnaire. The study group covered 7,716 adolescents: 5,086 children attending high school and secondary schools and 2,630 university students. Low physical activity was noted among 57% of schoolchildren and 20.84% of students. Analysis of the level of physical activity according to the IPAQ indicated that it was lower among girls, compared to boys. An additional analysis, with the consideration of the place of residence, showed that the highest percentage of the population with low physical activity was noted in the rural areas (29.30%), while among the urban inhabitants of cities with a population above 100,000 it was on the level of 23.69% and 20.57%. Median for weekly physical activity by respondents` gender was on the level of 1,554.00 MET*min. weekly among females, and 2,611.00 MET*min. weekly among males (p<0.000). The highest weekly physical activity expressed in MET*min. was observed among the inhabitants of towns with a population less than 100,000, whereas among the rural population and inhabitants of large cities with a population of over 100,000 the weekly physical activity was on a similar level (1,830.50 and 1,962.00 respectively). An extended analysis of respondents’ physical activity showed that during the day students spend significantly more time in a sedentary position, compared to schoolchildren. The presented results of studies indicate the necessity to continue and intensify actions to promote various forms of physical activity among students and schoolchildren. A constant decrease in physical activity observed among children and adolescents suggests that it is necessary to pay greater attention to this social group while developing health programmes.

Opis:
Background. Food less frequently used to provide the necessary nutrients for the survival and the body begins to play a role, which it is not able to cope with, leading to a dysfunctional its use. In an era of obesity, excessive interest in his appearance and lean silhouette assigning too much significance relates to a growing number of young women. Young women due to a period of their procreative years are particularly vulnerable to the consequences of abnormal eating habits that threaten the health of women and their offspring. Objectives. In young women of reproductive age, to determine the emotional and habitual reasons behind binge eating and the effect that restriction diets can have for achieving desired body mass in relation to physical activity and the willingness to improve their weight. Material and methods. Subjects surveyed were 372 women aged 18 to 27 years (mean 20.6 ± 1.4) who answered a questionnaire on dietary behaviour devised by Ogińska-Bulik and Putyński [21] which had been extended to include body mass perception/image, adoption of slimming diets, levels of physical activity and place of residence. The women’s actual body mass, height and body fat (adipose tissue content) were also measured. Results. Most subjects (63.9%) were dissatisfied with their figures whilst 33.5% underwent slimming diets at least once. Those overweight, complained much more about their figures compared to normal weight women (97.9% vs. 65.1%, p<0.01), as well as being respectively more emotionally prone to overeating (4.5 ± 2.2 vs. 5.2 ± 2 points round, p <0.01), but less for adopting any dietary restriction (3.5 ± 2.7 vs. 4.8 ± 2.3, p <0.01). Conclusions. It seems necessary to create a prevention and educational programs on proper nutrition and the perception of one’s own body as effective tools in reducing eating disorders in terms of the health of young women and multigenerational inheritance health of their offspring.
Wprowadzenie. Żywność coraz rzadziej służy do dostarczania potrzebnych do przeżycia składników odżywczych ciału a zaczyna odgrywać role, którym nie jest w stanie sprostać, co prowadzi do jej dysfunkcjonalnego zastosowania. W erze otyłości nadmierne zainteresowanie swoim wyglądem oraz przypisywanie szczupłej sylwetce zbyt dużego znaczenia dotyczy coraz większej grupy młodych kobiet. Młode kobiety ze względu na okres okołokoncepcyjny są szczególnie narażone na konsekwencje nieprawidłowych nawyków żywieniowych, które zagrażają zdrowiu kobiet i ich potomstwu. Cel badań. Badanie i ocena emocjonalnego i nawykowego objadania się oraz stosowania restrykcji dietetycznych w relacji do subiektywnej oceny posiadanej i oczekiwanej masy ciała, aktywności fizycznej i chęci jej zmiany wśród młodych kobiet w wieku prokreacyjnym. Materiał i metody. Badaniem objęto 372 kobiety w wieku od 18 do 27 (20,6 ± 1,4) lat. W badaniach stosowano Kwestionariusz Zachowań Związanych z Jedzeniem Ogińskiej-Bulik i Putyńskiego [21], poszerzony o ankietę własną zawierającą pytania dotyczące stosunku do masy ciała, częstości stosowania diet odchudzających, stopnia aktywności fizycznej oraz miejsca zamieszkania. Następnie dokonano pomiarów masy i wysokości ciała oraz zawartości tłuszczu w organizmie. Wyniki. Wśród badanych kobiet 63,9% było niezadowolonych z sylwetki, a 33,5% badanych odchudzało się chociaż 1 raz. Kobiety o nadmiernej masie ciała w porównaniu do kobiet z prawidłową masą ciała były najbardziej niezadowolone Związaz sylwetki (97,9% vs. 65,1%, p<0,01) i wykazywały największe tendencje do emocjonalnego przejadania (4,5±2,2 pkt vs. 5,2±2 pkt, p<0,01) oraz restrykcji dietetycznych (3,5±2,7 vs. 4,8±2,3, p<0,01). Wnioski. Konieczne wydaje się stworzenie programów prewencyjno-edukacyjnych w zakresie prawidłowego żywienia i postrzegania własnego ciała jako skutecznych narzędzi w ograniczeniu zaburzeń odżywiania w aspekcie zdrowia młodych kobiet i wielopokoleniowego dziedziczenia zdrowia u ich potomstwa.

Opis:
The present paper aims at discussing What Sunny Saw in the Flames by Nnedi Okorafor as a fantasy novel for children and young adults focused upon the question of self-identification. In the framework of fiction for younger audiences, the fantasy mode becomes a tool which allows to examine the topics important to young readers, such as identity and their place within the society, by providing a confrontation with the Other. The example of Nnedi Okorafor’s book, known in the USA as Akata Witch, shows how the instrumentation of a fantasy novel enables an exposition of the process in which the protagonist grows on the intellectual, emotional and cultural levels. In other words, the fantasy mode aids in the exploration of Sunny’s American-Nigerian origin, her albinism, coming of age and the comprehension of her identity. Simultaneously, as additional topics emerge from the analysis, it becomes visible that the question of the Self cannot be separated from the concept of the Other, with the lesson of empathy and respect for what is different.

Opis:
In this paper, we discuss the problem of articulation between levels in the educational system, as the transition from a rather more communicative, contentbased and holistic approach to English as a foreign language (EFL) teaching at primary level to more formal and explicit ways of foreign language (FL) teaching at secondary is often experienced as problematic by students and teachers alike (see, e.g., Muñoz, Tragant, & Camuñas, 2015). The results of a mixed methods analysis are presented, in which we analyzed, through a questionnaire and language experience essays, perceived continuity between input received in primary school and secondary school, as well as learners’ beliefs, attitudes and self-efficacy before and after they transitioned to secondary school. Twelve primary schools and six secondary schools in Switzerland participated in the study, with a total of 280 early learners of EFL (biological age 12-13 years, age of onset 8 years). We will argue that one of the main reasons why early FL instruction seems not to bear fruit later in secondary school is that, on the one hand, coherence in curriculum design and practice vary in a few-but crucial-aspects within and between primary schools. On the other hand, the fact that secondary education becomes a meeting point for mixed ability classes also seems to mitigate the potential advantages of an earlier start.

Opis:
Over the last hundred years and since the Second World War at the speed of the Great Acceleration, the Anthropocene has been intensively impacting the Northeast of Italy and, as a result, redrawn the Triangolo Industriale, shifting it towards the East, whereby its two prior western cities – Turin and Genoa – have been replaced with the production hubs scattered along the Via Emilia and Veneto. The coastal region has seen the foundation and robust growth of Porto Marghera with its freight, metallurgy, chemical, mechanical, shipbuilding, oil and electricity sectors; the Veneto plain has witnessed an expansion of SMEs; and Emilia has become home to multinational corporations. While not subject to industrialisation, the mountains of the Triveneto have not been exempt from a thorough modernisation on the scale unparalleled in the Italian Alps. Considering these changes, this paper surveys a range of literary works from Salgari to Scarpa (via Albertazzi, Zavattini, Buzzati, Guerra, D’Arzo, Pratt, Malerba, Altan, Nanetti, Benni, Rigoni Stern, Molesini, Costa, Corona, Carminati, Sgardoli, Tamaro, Tessaro and Ervas) in order to establish what role is given to environmental issues by the authors of children’s literature in the Northeast and whether (dis)continuities emerge in the body of their writings in this respect. The paper also investigates which authors present an active sensitivity useful for fostering an eco-consciousness and in what ways they do so. The methodology combines an array of critical tools developed in eco-pedagogical criticism, ecofeminism and the NatCul Matrix, geared to answering a series of questions: (1) Is basic environmental literacy offered? (2) Is a critical reflection on human primacy and environmental (in)sustainability implicit, explicit or absent? (3) How are humanity and nature related in children’s literature? (4) How is eco-justice approached? (5) What attitudinal role does the narrative assign to nature?
Negli ultimi cento anni, e dal secondo dopoguerra al ritmo della great acceleration, l’antropocene ha intensamente investito il Nord-Est e ridefinito il nuovo triangolo industriale verso Oriente, sostituendo ai due vertici occidentali del passato – Torino e Genova – la via Emilia e il Veneto. La costa ha visto sorgere i settori merci, metallurgia, chimico, meccanico, cantieristico, petrolifero, elettrico di Porto Marghera; la pianura veneta le SMEs e l’emiliana le multinazionali; le montagne del Triveneto, esentate dall’industrializzazione, non lo sono state da una profonda modernizzazione senza pari in tutto l’arco alpino italiano. Di fronte a questi mutamenti quale ruolo viene dato alle tematiche ambientali dagli autori delle letterature per l’infanzia e per ragazzi del Nord-Est? Emergono (dis)continuità in una comparazione di opere da Salgari a Scarpa, passando per Albertazzi, Zavattini, Buzzati, Guerra, D’Arzo, Pratt, Malerba, Altan, Nanetti, Benni, Rigoni Stern, Molesini, Costa, Corona, Carminati, Sgardoli, Tamaro, Tessaro ed Ervas? L’articolo indaga come e quali autori presentino nelle proprie opere una sensibilità attiva utile per la formazione di una ecocoscienza. La metodologia incrocia gli strumenti critici maturati negli ambiti della critica ecopedagogica, dell’ecofemminismo e della matrice NatCul.

Głównymi nieprawidłowościami wskazanymi przez ankietowanych były: brak wyposażenia pracowników w odzież ochronną oraz obuwie robocze, brak wyznaczenia stref niebezpiecznych na budowie, nieprzestrzeganie czasu pracy oraz nieudzielanie urlopu przysługującemu młodocianym i dopuszczanie do prac niedozwolonych pracownikom młodocianym.
The aim of the study was to assess the knowledge and awareness of young workers in the building industry regarding their health requirements and working conditions. A questionnaire survey was conducted among a representative group of 110 young employees in the building industry. It consisted of 82 questions divided into six sections (school, contract, training, employer, workplace, workstation). The main problems the young employees listed were as follows: no protective clothing and footwear, no indication of danger zones in construction sites, disregard for work time and not granting the leave young workers are entitled to, and permitting young people do work they should not be doing.

Introduction and objective. Since the characteristic of chronic non-specific lumbar dysfunction presents a high prevalence and morbidity, and that there are still conflicting results with the use of photobiomodulation, the aim of this study was to analyze the effect of photobiomodulation application in patients with chronic non-specific lombalgy. Materials and method. A quantitative, experimental, randomized study composed of 21 volunteers randomly separated into two groups: 1) the intervention group (IG), who were given an application of photobiomodulation (LED (617nm ±10%, 1,500 mW) and low-level laser therapy (830nm, 150 mW, beam area 12.57mm), combined energy of 8.4 J per area for one minute in four different locations: in regions of greatest pain referred to palpation, on a bilateral basis, area of the applicator – 23,8 cm2). 2) the control group (CG), in which the device remained switched-off during therapy. All subjects were evaluated by McGill and Roland Morris questionnaires before and at the end of 6 interventions (3 weeks). Results. For both McGill and Roland Morris total pain rates, there was no inter-group interaction or interaction between evaluation and group (p>0.05). In the comparison between evaluations (before and after), there was a significant difference (p<0.001). Conclusions. The use of photobiomodulation in these parameters in young patients with chronic non-specific lombalgy, was not more effective than the placebo for the relief of painful symptoms. Nor did it promote a decrease in the repercussion of lombalgy in the performance of daily activities.

Opis:
The history and publishing output of Nasza Księgarnia, Poland’s biggest publisher of children’s and young adult literature founded in 1921 and still operating, has been extensively researched by bibliologists and literature scholars over the last decades (Bylina, 1961; Aleksandrzak, 1972; Rogoż, 2009; Jamróz-Stolarska, 2014; Biernacka-Licznar, 2018a; Gawryluk, Lajborek & Korobkiewicz, 2021). However, the post-2000 productions of contemporary Polish writers and their translations into Italian have not attracted interest from Polish researchers yet. The paper aims to examine the publishing repertory of Nasza Księgarnia and identify the list of titles that made their way into the hands of the Italian reading public between 2012 and 2022. Based on the bibliometric method and interviews with the NK staff, the study generated reliable data and yielded a detailed account of the repertory released on the Italian publishing market in the last decade.
La storia e la produzione editoriale della casa editrice Nasza Księgarnia fondata nel 1921 a Varsavia e operante fino ad oggi, è un tema che è stato oggetto di intense ricerche condotte da bibliologi e studiosi di letteratura per l’infanzia negli ultimi decenni (Bylina, 1961; Aleksandrzak, 1972; Rogoż, 2009; Jamróz-Stolarska, 2014; Biernacka-Licznar, 2018a; Gawryluk, Lajborek & Korobkiewicz, 2021). La questione del repertorio editoriale di autori polacchi contemporanei le cui opere sono state scritte dopo il 2000, e la loro traduzione in italiano, non ha finora incontrato l’interesse dei ricercatori polacchi. L’obiettivo dell’articolo è quello di analizzare il repertorio editoriale di Nasza Księgarnia e stabilire un elenco di titoli che sono stati pubblicati in Italia nel periodo 2012–2022. L’uso del metodo statistico nello studio e le interviste con le persone responsabili dell’introduzione dell’offerta editoriale sul mercato italiano hanno permesso di ottenere dati affidabili e dettagliati per descrivere il repertorio che si è affacciato sul mercato editoriale italiano nell’ ultimo decennio.
