Opis:
The international community affirms the critical role of forests in climate change mitigation, which includes reducing emissions from degradation and deforestation, carbon stock conservation, sustainable forest management, and increasing carbon stocks in developing countries. It relates to land use and land cover changes. This study aims to review land use and land cover changes (LULC) in two decades, namely 2000-2010 and 2010-2020, and the impact on carbon stocks. Landsat satellite imagery in 2000, 2010, and 2020 are classified into six categories: built-up area, cropland, forest, water body, bareland, and grassland. This classification uses supervised classification. The accuracy kappa coefficient values obtained for the LULC 2000, LULC 2010, and LULC 2020 maps were 89.61%, 83.90%, and 87.10%, respectively. The most dominant systematic LULC change processes were forest degradation in 2000-2020; the transition of forest to cropland (349.20 ha), forest to bareland (171.19 ha), and forest to built-up area (661.68 ha). Loss of using the forest for other uses was followed by a decrease in carbon stock. There was a high decrease in carbon stock in the forest category (11,000 Mg C∙y-1). The results showed a significant change in land use and cover. The decline in the area occurred in the forest category, which decreased from year to year. Meanwhile, the built-up area increases every year. Carbon stocks also decrease from year to year, especially forests as the most significant carbon store, decreasing in the area.

Opis:
Omawiane orzeczenie odnosi się do instytucji umorzenia opłaty rocznej z tytułu wyłączenia gruntu z produkcji rolnej na cele kultu religijnego na rzecz związku wyznaniowego na podstawie art. 12 ust. 16 ustawy z dnia 3 lutego 1995 r. o ochronie gruntów rolnych i leśnych. Zasadniczym przedmiotem analizy jest kwestia sposobu i zakresu badania w postępowaniu administracyjnym przesłanek umorzenia należności publicznoprawnych w przypadku realizacji inwestycji o charakterze użyteczności publicznej z zakresu kultu religijnego. Rozważania zmierzają do ustalenia, jakie okoliczności organ administracji publicznej powinien wziąć pod uwagę, rozpatrując sprawę o umorzenie opłaty rocznej z tytułu trwałego wyłączenia gruntu z produkcji rolnej na rzecz związku wyznaniowego, a w szczególności czy weryfikacja zasadności wniosku o umorzenie powinna ograniczać się wyłącznie do oceny ziszczenia się przedmiotowych przesłanek przyznania ulgi przewidzianych we wskazanym wyżej przepisie, czy też powinna obejmować także uwarunkowania podmiotowe, tj. analizę sytuacji związku ubiegającego się o przyznanie ulgi. Zaprezentowane rozważania uzasadniają zaaprobowanie stanowiska sądu wskazującego na konieczność dwuetapowego badania przez organy administracji okoliczności warunkujących umorzenie opłaty rocznej. W pierwszej kolejności weryfikacji podlegają przedmiotowe przesłanki wymienione w powołanym wyżej przepisie, a następnie powinna zostać szczegółowo zbadana rzeczywista i finansowa sytuacja beneficjenta umorzenia opłaty rocznej. Taki wniosek znajduje oparcie w celu ustawy o ochronie gruntów rolnych i leśnych oraz w istocie działania organu wydającego decyzję, który rozstrzyga sprawę w ramach uznania administracyjnego.
The judgment under discussion pertains to the institution of remission of the annual fee for withdrawing land from agricultural production by a religious organization for purposes of religious worship pursuant to Article 12 para. 16 of the Act of 3 February 1995 on the Protection of Agricultural and Forest Land. The article concentrates on the method and scope of examining in administrative proceedings the conditions for remission of public dues in the case of public utility investments in religious worship. The aim is to determine the circumstances which should be taken into account by public administration when considering applications for remission of the annual fee for permanent withdrawal of land from agricultural production. In particular, the article aims to establish whether investigating the legitimacy of an application should only be limited to assessing fulfilment of the legal conditions for granting the relief indicated in the above-mentioned provision or whether it should also involve an analysis of entity-related factors, i.e., the situation of an applicant organization.  The analysis confirms that, in line with the position of the court, the investigation of the conditions for remission of the annual fee by administrative authorities should comprise two stages, involving an examination of both the objective conditions for granting the relief and the actual and financial situation of the beneficiary. This conclusion is supported by the purpose of the Act on the Protection of Agricultural and Forest Land and the special character of the activity of the authority issuing the decision as a decision-maker entrusted with administrative discretion.

As You Like It
Opis:
In Utopia (1516) Thomas More created a humorous world with a serious purpose. His invented republic was a place where existing conventions and structures did not exist, allowing the positing of alternatives. The creation of alternative worlds which satirise or critique contemporary society is a technique employed by writers in most genres, in most periods and in most cultures. More’s work is interesting for us in this context at least in part because of the likelihood that Shakespeare was familiar with it. When he created The Forest of Arden in As You Like It, for some of the characters there are utopian elements in their experience of that place. But Arden is not only a putative Utopia. Arden also contains elements of the pastoral Arcadia, again drawing upon ancient precedents, but more recently explored by English poets Edmund Spenser in The Shepherd’s Calendar (1579) and Philip Sidney in The Countess of Pembroke’s Arcadia (1593). This article interrogates the use of Utopian and Arcadian elements in the creation of one of Shakespeare’s most complicated plays. Like More’s Utopia its intention is comic. Like Sidney’s poem it is romantic, but unlike both of them it is ultimately about returning to a real world, with new perceptions of who we are, not as a society but as individuals.

Opis:
Research background: Even though unintentional accounting errors leading to financial restatements look like less serious distortion of publicly available information, it has been shown that financial restatements impacts on financial markets are similar to intentional fraudulent activities. Unintentional accounting errors leading to financial restatements then affect value of company shares in the short run which negatively impacts all shareholders. Purpose of the article: The aim of this manuscript is to predict unintentional accounting errors leading to financial restatements based on information from financial statements of companies. The manuscript analysis if financial statements include sufficient information which would allow detection of unintentional accounting errors. Methods: Method of classification and regression trees (decision tree) and random forest have been used in this manuscript to fulfill the aim of this manuscript. Data sample has consisted of 400 items from financial statements of 80 selected international companies. The results of developed prediction models have been compared and explained based on their accuracy, sensitivity, specificity, precision and F1 score. Statistical relationship among variables has been tested by correlation analysis. Differences between the group of companies with and without unintentional accounting error have been tested by means of Kruskal-Wallis test. Differences among the models have been tested by Levene and T-tests. Findings & value added: The results of the analysis have provided evidence that it is possible to detect unintentional accounting errors with high levels of accuracy based on financial ratios (rather than the Beneish variables) and by application of random forest method (rather than classification and regression tree method).

Opis:
This article concentrates on an inquest held by the local commission in Sanok into the common rights claimed by the inhabitants of the town of Rymanów in the latter half of the 19th century. The negotiations, which commenced in 1859, sometimes took a heated turn. They were attended by much conflict and misunderstanding, equally between the manor and the town as among the townsfolk themselves. Conclusions drawn from the analysis of the archive source provided the basis on which to evaluate the activities of each of the parties – the town’s agents and the landlords – and, interestingly, those of the commissioners and other officials in the public administration, whose decisions exhibited bias. The townsfolk began the negotiation from a position of certainty and conviction of the legal force of Prince Czartoryski’s privilege granting the disputed common rights to them. The manor’s agent, on the other hand, took a bold position, which he consistently maintained. He disputed the authenticity of Czartoryski’s grant and even the fact that the Prince had ever held the manor. This approach ultimately proved successful. Attention is also drawn to the role played by local commissioners and the officials in the National Commission in Lviv, the latter making the most important decisions. The first phase demonstrates the commissioners’ influence on the original outcome. The rationale given for the second decision, on the other hand, shows the arbitrariness with which the Lviv Commission made its ruling, based on just one official document. Analysis of the proceedings highlights a more general trend prevalent in Galicia, first described in the example of Rymanów. This is a case in which two consecutive inquests in the same matter ultimately ended in a negative decision. In other words, the townsfolk’s claims were dismissed, and they were denied any common rights eligible for buyout or regulation.
Artykuł koncentruje się na dochodzeniu przeprowadzonym przez sanocką komisję lokalną względem praw służebnych, o których uznanie pretendowali mieszczanie rymanowscy w II połowie XIX w. Pertraktacje rozpoczęte w 1859 r. miały chwilami gwałtowny przebieg. Towarzyszyły im konflikty i nieporozumienia zarówno między samymi mieszczanami, jak i na linii miasto – dwór. Wnioski płynące z analizy źródeł archiwalnych posłużyły do oceny działań każdej strony biorącej udział w dochodzeniu – pełnomocników miasta, właścicieli ziemskich oraz, co wyjątkowe, komisarzy i administracji państwowej, której decyzje nosiły znamiona stronniczości. Mieszczanie stanęli do pertraktacji w pewności powodzenia i z przekonaniem o mocy prawnej przywileju księcia Czartoryskiego nadającego im służebności. Pełnomocnik dworu natomiast przyjął odważną pozycję w negocjacjach i konsekwentnie ją utrzymywał. Zanegował autentyczność wspomnianego przywileju, jak również to, że Czartoryski był kiedykolwiek właścicielem Rymanowa, co finalnie okazało się skuteczne. Na uwagę zasługuje również rola komisarzy lokalnych oraz decydentów urzędujących w Komisji Krajowej we Lwowie, podejmującej najważniejsze decyzje. Pierwszy etap dochodzenia pokazuje bowiem wpływ komisarzy na kształt początkowego orzeczenia. Uzasadnienie drugiego wyroku wskazuje natomiast na dowolność w postrzeganiu aktów prawnych przez lwowską Komisję, która oparła swoją decyzję na zapisach jednego dokumentu urzędowego. Analiza przebiegu postępowania ukazuje znajdującą odzwierciedlenie w wielu miejscach Galicji tendencję, która na przykładzie Rymanowa została opisana po raz pierwszy. Koncentruje się na przypadku, w którym dwukrotnie podejmowane dochodzenie skończyło się ostatecznie decyzją odmową. Innymi słowy, odrzucono pretensję mieszczan i zanegowano istnienie praw służebnych, które podlegałyby wykupowi lub regulacji.

Environmental changes affect edge populations first and the strongest. The aim of this study was to document the historical and current occurrence of the moose Alces alces L. along the western edge of its range in Poland and Europe. Our studies were conducted in central Poland, in the area of Experimental Forest Station of Warsaw University of Life Sciences (WULS) in the vicinity of Rogów village (225 km2 of field and forest mosaic, forest cover approx. 20%). We reviewed all available historical data as well as recorded direct observations. This included data collected through various methods such as drive counts, night spot-light and thermal vision counts along transect routes, snow tracking, camera-traps and pellet group counts. Occurrence of moose and changes in its abundance in the area of the Experimental Forest Station in Rogów reflected trends in the abundance of the species and in its range throughout the whole country. Currently, direct observations of moose or signs of its presence are recorded in the whole study area. However, in this very fragmented landscape, the species does not form a stable population but the observed individuals are most likely migrating from their main refugees. Signs of presence were recorded only once during drive counts and snow tracking in the central part of the study area (2011–2018) registered 0.03 moose tracks/ km/24 h. Snow tracking conducted in January and February of 2021 was focused on moose specifically and revealed the presence of 10–11 individuals in the entire study area. Pellet group counts along transects (spring 2020 and 2021) resulted in a density index of 0.33 pellet groups/km/100 days of accumulation, while data from camera-traps (2011–2020) indicated an increase in the relative abundance index. In the biggest forest complex of the study area, this index increased three fold, whereas in smaller forest complexes only two fold. Assuming that 11 individuals were present, the population density was 0.49 ind./1000 ha in terms of total area and 2.6 ind./1000 ha in terms of forest area. In the following years, a further population increase can be expected reflecting growth in the core population.

Opis:
In this research sawdust samples of Ecalyptus globulus and Cupressus lusitanica were evaluated for bioethanol productions. The sawdust samples were first pretreated with three white rot fungi alone and also by combining the white rot fungi with mild NaOH and steam. Both the fungal and combined pretreated samples were then hydrolyzed with hydrolytic enzymes from three cellulolytic wood rot fungi. Finally, the resulting sugars were fermented into bioethanol using S. cerevisae in anaerobic conditions. Results obtained, in general, indicated that bioethanol amount produced in all cases of sawdust management was significantly higher than the amount obtained from the un-pretreated sawdust samples (p<0.05). In both fungal alone and combined pretreated sawdust samples, higher ethanol yield was obtained from E. globulus than from C. lusitanica. Similarly, combination with NaOH showed better bioethanol yield over combination with steam. The highest alcohol concentration was obtained when pretreated NaOH-006-2G and hydrolyzed with enzymes from 033-1G and followed by results when pretreated with 005-1G and 003-2G, respectively, and hydrolyzed with enzymes from 033-1G.

Opis:
The aim of the considerations is to determine how the concept of land take and the related EU target of no net land take by 2050 function in the law (especially in Poland), and then to assess to what extent the perception of this formula in the law is relevant to the model of land protection and whether it has the potential to increase the effectiveness of the legal regulation in this respect. Land take is a concept that describes one of the main threats to the protection of land as an environmental resource. First attempts to incorporate this formula into the legal system of land protection have already been made. In European Union law, this was done by setting the goal of no net land take target by 2050. This objective, however, is neither binding nor specified in secondary legislation. The concept of land take and the target related to it may have a positive impact on the effectiveness of the land protection system. However, it is essential that the legal instruments are integrated and are of a binding character. The Polish legal system has reiterated the concept of indirect land take, and no national target in this respect has been adopted. This model is an example confirming the thesis that special and extensive legal regulations do not always guarantee that the protection measures are effective. Also, while it illustrates the importance of integrating individual legal regulations, it shows as well that the weaknesses of one of them (in Poland the inefficiency of spatial planning) cannot be compensated for by developed instruments in another area of law.
L’articolo si propone di determinare come il concetto di occupazione dei terreni/consumo di suolo (land take) e il relativo obiettivo dell’UE di arrivare a quota zero entro il 2050 funzionino nel diritto (soprattutto polacco) e, di seguito, di provare a valutare in che misura la percezione di questa formula in diritto sia importante per il modello di tutela dei terreni e se abbia il potenziale per aumentare l'efficacia giuridica dei regolamenti in questo ambito. La land take è una concezione sviluppata, descrive una delle principali minacce alla tutela della terra come risorsa. I primi tentativi, per includere questa formula nel sistema giuridico di tutela della terra, sono stati intrapresi. Nel diritto dell'Unione Europea ciò è stato fatto fissando l’obiettivo di arrivare, per quanto riguarda l’occupazione dei terreni, a quota zero entro il 2050. Tuttavia, esso non è vincolante, né specificato nelle disposizioni di diritto derivato. La concezione di occupazione dei terreni e il relativo obiettivo possono influenzare positivamente l'efficacia del sistema di tutela dei terreni. Tuttavia, è necessario combinare gli strumenti giuridici sotto molteplici aspetti e a multilivello, e renderli vincolanti. Il sistema giuridico polacco ha adottato la concezione di occupazione dei terreni in maniera indiretta, nessun obiettivo nazionale al riguardo è stato prefissato. Il modello polacco è un esempio di conferma per la tesi che una regolazione giuridica specifica ed estesa non garantisce l'efficacia della tutela stessa. Illustra inoltre quanto è importante collegare le singole regolazioni giuridiche, nonché l'incapacità di compensare le debolezze di una di esse (in Polonia l’inefficienza dei piani regolatori) con strumenti sviluppati in un'altra area del diritto.

Opis:
The paper presents the standardization of felling and production of assortments costs by the method of grouping forest districts with similar natural conditions. The standard costs were compared with the incurred (actual) and planned costs, and the method of determining the standard unit costs of felling and production of assortments was assessed in terms of its use in the State Forests National Forest Holding financial system. Source materials for 2017 were obtained from the databases of the State Forests Information System for all forest districts and used to develop standard unit costs. The method of costs standardization determined 12 uniform groups of forest districts in terms of the structure of harvested timber assortments and the share of dominant tree species in the total area of forest districts. Then for each group 5% of outlying values were excluded based on mean and standard deviation. Next, average value for such truncated number of cases was calculated and defined as the standard costs. Pearson linear correlation was used to examine the relationship between actual, planned and standard unit costs. We found significant relationship between the investigated types of costs. The significant relationship was found also among weighted averages of actual, planned and standard unit costs calculated for regional directorates of the State Forests. No significant differences was observed between average unit costs not reflected in the financial practice of the State Forests. Slight differences in analysed costs constitute significant cost values on the scale of the whole company as felling and production of assortments consists of many tasks. The presented method of forest districts grouping should be used to standardize unit costs of felling and assortments production, which would be helpful in financial planning at the various levels of the management in the State Forests. Values omitted in the presented method require additional analyzes. Separate assessment is also required for the factors (justified or unreasonable) causing deviations in forest districts obtaining actual costs departing from the costs of other forest districts included in the same assortment and species group.

Opis:
Climate change creates a big challenge for forest science. One of several problems calling for urgent solution concerns the elaboration of the scientific foundations for determination of the species composition of forest stands under changing environmental conditions. This problem is particularly acute in case of declining Norway spruce stands in the Sudety Mountains (SW Poland). The paper presents the main principles used to develop a model allowing determination of the most desirable species composition for any given forest stand occurring in the Sudety region. These principles include: 1) an assumption that a basis for species composition planning should be a forest site type, corrected by means of site index of the currently existing forest stand, 2) a supposition that one should broadly consider present processes taking place in Sudety stands, particularly, an intense forest dieback caused by recurring drought periods and strong winds, 3) a postulate that one should consider the differences between tree species in respect to their reaction to particular abiotic factors, 4) an assumption that majority of stands should consist of several different tree species, 5) an assumption that introducing on a wide scale Douglas fir, well−adapted to the conditions of the Sudety Mountains, is allowed, 6) an idea that one should take into account differentiated production potential and varied timber quality of particular tree species, 7) an assumption that one should consider the main features of topography (altitude, exposition, slope) as well as 8) fine elements of micro−topographical situation, as a basis for introduction of different tree species. The results obtained by means of the model based on the above mentioned principles are presented on the example of two forest districts: Lądek−Zdrój (fig. 4a, b) and Szklarska Poręba (fig. 5a, b). In both cases, a necessity to diminish the share of Norway spruce and to increase the share of such species like common beech, silver fir, Douglas fir and European larch is demonstrated. One may expect that projected compositions, taking into account the most appropriate tree species and their most suitable localizations, will allow establishment of forest stands which will be more resistant to drought and wind and, thus, will be more able to fulfill several important forest functions (related to water and soil protection, protection of forest biodiversity and timber production).

We tried to define the reasons for staying in forest environment, indicate the most valuable qualities of forest area and factors that disturb the presence in forest. We indicated the greatest threats to the forest environment and expectations of the population regarding the facilities for using the forest environment for leisure purposes as well as recreational and tourist activities. The diagnostic survey method was used. The questionnaire included 10 closed questions, half of which were used for the purpose of this work. The attitude was measured with a five−point Likert scale after the use of activities related to the construction and validation. The sample consisted of 1068 adult respondents, who were chosen according to the place of residence (village, town up to 30 thousand and over 30 thousand inhabitants), age (up to 25 years, from 26 to 40 years, from 41 to 55 years as well as older than 56), gender and 6 regions of Poland. We applied the analysis of discriminant function in statistical analysis. The classification function was used in the form of calculating coefficients that were determined for each of the created groups. The main goals of stay in forest are group trips, running and cycling, as well as health values of this environment and observation of fauna and flora combined with the collection of forest undergrowth. The main advantages of this environment are healthy and fresh air, and peace. Factors disturbing stay in the forest include its littering and too many visitors, while the biggest threats are forest fires and its excessive exploitation by visitors. It is expected that the infrastructure supporting relaxation in the forest environment will be developing. Polish forest resources through the richness of natural values and with proper supply of tourist and recreational infrastructure can be the main area of creating tourist and recreational products. The education of visitors is expected to improve the perception of forest resources as a place of rest and regeneration of vital forces.

Opis:
The article presents the size and weight of needles in 30−year−old Scots pine stands over one year with regard to the site conditions in which they grow (fresh mixed coniferous and fresh coniferous habitats). Two rectangular 1−hectare sample plots, which differed from one another only with the habitat type, were set up in Maszewo forestry in the Cybinka Forest District (western Poland). The plots were divided into 100 one−acre subplots, which were ascribed numbers from 1 to 100. In order to pick 10 plots a random number generator was used. The middle of the chosen plot became the central point of the 1−acre circular sample plots, where the measurements of all diameters at breast height and the height of every fifth tree were taken. Moreover, it was also the place where a square needle collection container (20 cm high, 1 m2 area) was located. The empty containers were placed in both experimental plots on 1st August 2017 and they were emptied on the first day of each month, throughout the entire year. The entire material was dried at the temperature of 65°C with an induced air flow. The needle mass was measured with the accuracy up to 0.001 g. Out of the samples collected each month, 300 needles were chosen at random in order to measure their length (after they were scanned with WinFOLIA program the size of each individual needle was established). Throughout the entire year, on fresh coniferous habitat the mass of the fallen needles was 2.8203 t/ha and it was by over 20% higher than it was determined for the fresh coniferous habitat. The lowest mass of the needle fall in each stand was in January, and the greatest in September on the fresh coniferous habitat, whereas in October on the fresh mixed coniferous habitat. In both of these cases, it was more than a half of the needle mass for the entire year. The average length of the fallen needles was in each month smaller on the fresh coniferous habitat and the differences between the analyzed stands were significant. The difference was the smallest (3.3%) in May, while the greatest (18.8%) in February. Moreover, significant differences in the length of the needles in the particular months in both types of stands were observed. The coefficient of variation for the needles length on the fresh mixed coniferous habitat ranged from 17.4 to 22.8%, whereas on the other habitat it varied between 14.2 and 21.6%. The mean of the coefficients of variation for the particular months was lower by 2.0% and for fresh coniferous habitat it reached 18.25%.

Opis:
The subject of the article is forest education understood as a form of education regarding the interdependence between man and nature. The authors intend to show the alternative nature of forest education to traditional teaching methods. The first part of the article consists of reflections showing the relationship between man and nature. This justifies not only the need to protect the environment. The protections should be understood as care for natural resources, but also education in this area. The second part will introduce education for sustainable development in the context of the 2030 Agenda. The third part characterizes forest education through the operations of the Center for Nature and Forest Education in Warsaw.
Przedmiotem artykułu jest edukacja leśna, odczytana jako forma kształcenia dotycząca współzależności między człowiekiem a przyrodą. Autorzy stawiają sobie za cel ukazanie alternatywnego charakteru edukacji leśnej wobec nauczania prowadzonego w tradycyjny sposób. Pierwszą część artykułu tworzą rozważania ukazujące relację człowieka i przyrody. To uzasadnia nie tylko potrzebę ochrony środowiska rozumianej jako troska o zasoby naturalne, lecz także edukacji w tym zakresie. W części drugiej przybliżona zostanie edukacja dla zrównoważonego rozwoju w kontekście Agendy 2030. W trzeciej części scharakteryzowano edukację leśną na przykładzie działalności Centrum Edukacji Przyrodniczo-Leśnej w Warszawie.

Opis:
The development of tourism can be intensified with the close cooperation of many institutions and organizations. Wildlife tourism is a form of tourism organized in forest areas. This form of recreation creates opportunities for an activation of many institutions, and economic units, as well as areas with a particularly high level of afforestation. Forest areas have unique and one of its kind tourist values, which should be used by society. Therefore, efficient institutions and organizations should effectively support its development. Wildlife tourism, as a form of rest and recreation, should be promoted and dynamically developed. At the same time, promotion measures must be carefully selected. The aim of the study is to present dominant institutions and organizations that support the development processes of sciences and determine their role and importance in the organizational system. The article’s study uses specialist literature and observation method.
Rozwój sylwanoturystyki może być intensywniejszy przy ścisłej współpracy instytucji i organizacji na rzecz jej rozwoju. Sylwanoturystyka, jest to forma turystyki organizowana na obszarach leśnych. Taka forma wypoczynku stwarza szanse aktywizacji wielu instytucjom, jednostkom gospodarczym, a także obszarom o szczególnie wysokim stopniu zalesienia. Obszary leśne posiadają niepowtarzalne i jedyne w swoim rodzaju walory turystyczne, które powinny być wykorzystywane przez społeczeństwo, a sprawnie działające instytucje i organizacje powinny skutecznie wspierać jej rozwój. Sylwanoturystyka, jako forma wypoczynku i rekreacji musi mieć motywację do dynamicznego rozwoju, a przy tym muszą być trafnie dobrane środki promocji. Celem opracowania jest zaprezentowanie dominujących instytucji i organizacji, wspomagających procesy rozwojowe sylwanoturystyki oraz określenie ich roli i znaczenia w systemie organizacyjnym. W opracowaniu artykułu wykorzystano literaturę specjalistyczną oraz metodę obserwacji.
