Opis:
In this study, morphology of a Brazilian population of Eschaneustyla terricola Foissner, 1982 and a Chinese population of E. lugeri Foissner, Agatha & Berger, 2002 were studied based on living observation and protargol impregnation. Several stages of morphogenesis in E. lugeri were reported and the most remarkable features are characterized as follows: (1) partly renewal of adoral zone of membranelles in the proter and the parental midventral cirri do not join the construction of the opisthe’s oral primordium; (2) three or four buccal cirri each develop from one frontoventral cirral anlage and undulating membranes anlage generates two frontal cirri; (3) frontoventral cirral anlagen n and n-1 develop de novo and in the frontoterminal cirral row, respectively; (4) intrakinetal development of marginal and dorsal kineties anlagen; (5) fusion of macronuclear nodules into a single mass.

Opis:
The urostylid family Pseudokeronopsidae Borror and Wicklow, 1983 was considered to be a well-outlined taxon. Nevertheless, recent evidence, including morphological, ontogenetic, and molecular information, has consistently revealed the polyphyly of this family. In the present work, a new population of Thigmokeronopsis stoecki Shao et al., 2008 was found and its binary divisional process was described for the first time. In addition, the morphogenetic features of Thigmokeronopsis species and all the other pseudokeronopsids, for which detailed ontogenetic data are available, were rechecked and compared. This reveals that: (1) the ontogenetic process of T. stoecki corresponds well with its congeners T. jahodai and T. rubra except for the macronuclear behavior; (2) Apokeronopsis and Thigmokeronopsis share a similar ontogenetic mode despite of the differences in the number and origin of their buccal cirri; (3) most pseudokeronopsids share the same pattern in the origins of their oral primordia and fronto-ventral-transverse cirral anlagen, except for Pseudokeronopsis similis, which may not be a valid member of the family Pseudokeronopsidae.

Opis:
The morphology and morphogenesis of two populations of the soil hypotrichous ciliate, Parakahliella macrostoma (Foissner, 1982) Berger et al. 1985, isolated from northwest China, were investigated based on specimens examined in vivo and stained with protargol. Our populations resemble the original one in terms of their live characters and cirral pattern. The main events during binary fission are as follows: (1) the parental adoral zone of membranelles is retained completely by the proter; (2) both in the proter and in the opisthe five frontal-ventral cirral anlagen are recognizable; (3) the marginal rows and dorsal kineties develop intrakinetally. In addition, the SSU rRNA gene was sequenced for the genus Parakahliella for the first time. Molecular phylogenetic analyses suggest that two populations of the genus Parakahliella cluster together and have a close relationship with species of Oxytrichidae.

Opis:
The problem of acceleration of growing processes during childhood and adolescence has been considered for a long time. The observations on this subject date back to the 19th century, however the attempts to summarize this phenomenon were dated to the 20th century. At the beginning of the 20th century Stratz, distinguishing the period of early and late childhood, had mentioned about three periods of deceleration and two periods of acceleration of growing processes. In 1930 also Boas identified the pubertal spurt. Ones of the first longitudinal studies had been organized in Krakow by Talko-Hryncewicz and continued in 1919-32. The results had been elaborated by Jasicki in 1934-48 and he revealed that there are two periods of acceleration of growing processes.In Poland this acceleration in growth had been called “the maximal height velocity.” The growth spurt at the end of childhood (around 7 years) has been pointed out by many authors in the 1930s, and in 1947 Tanner called it the mid-growth spurt. In 1961 Wolański pointed out that there are several growth spurts in childhood and called them pre (school) spurts. Consequently, in 1962 he had distinguished pubertal spurts for many somatic characteristics, and in 1964 – at least two pubertal spurts in height. Wolański had been analyzing the age at pubertal spurt followed by the age at menarche in rural and urban girls and concluded that these events are further apart if the pubertal spurt occurs later. The further analysis of these phenomena had been postponed because of the unfortunate statistical methods which presented data as mathematically smoothed growth curves and many details of individual growth patterns have been eliminated.Only two last decades the daily and monthly studies of growth processes have returned to favor, and the relationship between the rate and age at prepubertal and pubertal spurts has been studied again. In about 1980 the growth spurt at the turn of childhood and juvenile periods was again under study, but only during the last decade several growth spurts have been manifested. The number of prepubertal growth spurts has a very important impact on age and velocity of the pubertal spurt. If the number of prepubertal spurs is grater, the pubertal spurt occurs later and is less manifested. There are still many controversies according to the age of pubertal spurt and final body height. It may be similar to the relationship between menarche and final body height. It is observed that between populations there is a negative correlation between age at menarche and adult height, whereas between women within the population this correlation is positive (Wolański 1979).

First, the relationship between colours and time is analysed. The suggested description of the stages of life through the colour spectrum allows answering the question of how the respective stages of human life are determined by the colours assigned to them by the culture.

Opis:
One of the indicators of an optimally conducted training process is the athlete's achievement of sports success in all age categories. The analysis of sports career development is helpful in determining the periods of maximizing and maintaining sports results, but also in choosing the development path leading to the achievement of top-level results at the senior age. The aim of the study was to assess the development of sports championship in the 400-metre dash, comprising sports careers of 400 m medalists of the World Cadet and Junior Championships and European Junior Championships in the most important sports events in the senior age category, namely the European Championships, World Athletics Indoor Championships, World Championships, and the Olympic Games. The analysis involved a group of 69 male and 69 female medalists of the European Junior Championships, 27 male and 27 female medalists of the World Youth Junior Championships as well as a group of 48 male and 48 female medalists of the World Junior Championships in the 400 m. The research revealed that from 4% to 7% of the World Cadet Championships medalists and 1-3% of the male and 4-6% of the female medalists of the European Junior Championships achieved their highest sports success by winning medals at the World Championships and the Olympic Games. 6% to 10% of the studied World Junior Championships male medalists were successful in the World Championships. Among the World Championships female medalists, 12% won medals at the World Athletics Indoor Championships, 6% won medals at the World Championships, and 2% won the Olympic Games medals.

Opis:
In 1988, we found a large (250–400 × 80–150 μm in protargol preparations) Uroleptus-like hypotrich in a freshwater pond in Harbin, China. We studied the morphology of non-dividers and the cell division using protargol impregnation. Since we disregarded live observations and due to the lack of a modern revision of the uroleptids, a final identification was not possible. A detailed comparison with the most similar limnetic Uroleptus-like hypotrichs and with Rigidothrix goiseri revealed that the Chinese population is very likely identical with Uroleptus magnificus [basionym Holosticha (Paruroleptus) magnificus Kahl, 1932], a very rare species possibly confined to limnetic, stagnant water bodies of the holarctic region. Besides the large size, main features of U. cf. magnificus are: (i) about 80 adoral membranelles; (ii) three or four inconspicuous transverse cirri; (iii) 5–8 dorsomarginal kineties; (iv) the oral primordium originates de novo left of the postoral midventral cirri; (v) the frontal-ventral-transverse cirri anlagen of the proter and the opisthe originate via primary primordia; (vi) the left frontal cirrus of the proter originates from the middle portion of the disorganizing parental paroral; (vii) the parental endoral becomes the undulating membrane anlage for the proter; and (viii) the frontoterminal cirri originate in the plesiomorphic manner, that is, from the rearmost anlage. A compilation reveals that 59 species, subspecies, etc. have been described in or assigned to Uroleptus and Paruroleptus, but only about 50% of them seem to be true uroleptids. Many species of this predominantly limnetic group are little known.

Opis:
Tachysoma pellionellum Stokes, 1887, a freshwater ciliate isolated from Stone Mountain State Park, North Carolina, was studied in vivo and after staining with protargol. The population was characterized mainly by having the typical 18 frontal-ventral-transverse cirri; posterior ends of left and right marginal rows not confluent; five dorsal kineties and one dorsomarginal kinety; two macronuclear nodules near left cell margin with one or two micronuclei between them; contractile vacuole located at mid-body near left margin. Morphogenesis is characterized as follows: (1) in the proter, the parental adoral zone of membranelles is retained completely; (2) 18 frontal-ventral-transverse cirri are derived from the anlage of the undulating membrane and the five streaks of the frontal-ventral-transverse anlagen; (3) marginal rows develop intrakinetally; (4) anlagen of dorsal kineties 1, 2 and 4 develop in the parental structure and anlagen of dorsal kineties 2 and 4 fragment in the posterior region forming anlagen of dorsal kineties 3 and 5; (5) only one dorsomarginal kinety formed; (6) the two macronuclear nodules fuse into a single mass, which then divides. Phylogenetic analyses based on sequences of the gene coding for SSU RNA revealed a close relationship between T. pellionellum and the Oxytricha clade, both of which grouped with Kleinstyla dorsicirrata and Heterourosomoida lanceolata.

The central problem of development psychology, and psychology in general, is a way of dividing of life into periods called in European tradition as a periodization of ontogenesis. Nor just the division of life into separate periods, but the creation of a theory that would explain why the individual life is divided into periods in a certain way. Only with such a theory, it is possible to wonder about the age periods and the duration of their borders. The solution of second problem appears as an objective of this article.

Two oxytrichid freshwater ciliates, Apoamphisiella tihanyiensis (Gellért and Tamás, 1958) Foissner, 1997 and Notohymena australis (Foissner and O’Donoghue, 1990) Berger, 1999, were recorded for the first time in Lake Biwa, a 4-million-year-old lake located at the Shiga Prefecture in Japan. Their morphology was investigated based on observations of live and protargol-impregnated material. Based on the present observation and previous descriptions, A. tihanyiensis is characterized by having an elliptical body shape, yellowish cortical granules, two long frontoventral rows, enlarged frontal and transverse cirri, highly variable numbers of frontoventral, and postoral ventral cirri, and six to 11 caudal cirri arranged in three short rows. New data confirm the presence of pretransverse ventral cirri in this species. Morphologically, N. australis differs from its congeners in having the following combination of characters: greenish cortical granules, the cirrus V/2 located slight anterior to the leftmost transverse cirrus, dorsal kinety 3 almost as long as body, and seven to 10 caudal cirri arranged in three short rows. Morphogenesis in N. australis shows the same pattern as in N. apoaustralis but differs from that of other congeners in the origin of oral primordium and the formation of more than just three caudal cirri.

Opis:
This paper investigates the morphology and morphogenesis during binary fission of a Chinese population of Euplotes amieti Dragesco, 1970, a fresh water form which has previously not been well defined. This organism is morphologically very similar to the well-known Euplotes eurystomus but differs from the latter both in the number of dorsal kineties and the molecular data. According to the information obtained, it is characterized by a combination of features including nine frontoventral cirri, ca. 60 membranelles, 12–15 dorsal kineties, a macronucleus in the shape of the number 3, and a ‘double-eurystomus’ type of silverline system. Its morphogenesis proceeds broadly in the same pattern as in its congeners. In this study, the SSU rRNA gene was sequenced for the first time, and phylogenetic analyses indicated that it is closely related to the eurystomus-aediculatus-woodruffi- complex. Considering the extreme similarities in morphology between E. amieti and E.eurystomus, we believe that the four sequences (four isolates) under the name of Euplotes eurystomus (No. FR873716; FR873717; EF193250; AJ310491 deposited in GenBank) are very likely from misidentified material; that is, they represent different populations of Euplotes amieti.

The contribution presents the relationship between the frequency of physical activity during the week and fields of life quality of kindergarden teachers in three mature parts. In the research took part kindergarden teachers from Slovakia (n = 211) who were divided into groups according to their ontogenesis. The life quality was observed with a modified questionnaire SQUALA and the physical activity level frequency during the week. The data is presented by descriptive characteristics (n, M, SD) and statistic importance of differences, let us say relationships which are measured by non-parametric methods (W, U, rs), by the importance level (p<0.05; p<0.10). The results showed the most numerous correlations between the physical activity during the week and fields of life quality of teachers in age group from 36-46 years (middle mature) who do the physical activity M: 3.250 during the week by SD: 2.761. In this group were proved positive correlations with the field of physical well-being (p<0.01), psychosocial well-being (p<0.01), material well-being (p<0.01), education (p<0.10), free time (p<0.05), appearance and property of things (p<0.01). Specially this age is characteristic by reaching the highest goals of physical and mental performance. In the groups of younger and older mature we do not find so many important relationships between the physical activity and some fields of life quality. In these groups we did not find any important correlations of physical activity with physical well-being where the group of young mature reached the same level of physical activity as the group of middle mature. The conclusions show the importance of physical activity in life of kindergarden teachers, they show some possibilities of influencing the life quality through the physical activities but also creating the optimal conditions possibilities to increase the life quality in social environment. The contribution is part of the Ministry of Education grant KEGA 014UKF-4/2013 Improving the quality and level of health of adolescents by means of physical activity in primary and secondary schools.
