The aim of this thesis is to elucidate the meaning of play which constitutes the genuine happiness of human being in Plato's '$heort{\bar{e}}$' and Aristotle's '$schol{\bar{e}}$'. Until now '$heort{\bar{e}}$', a divine act which communicate with original divinity, was differentiated from paidia. And '$schol{\bar{e}}$' was understood as activities in spare time opposed to labour. Plato put '$heort{\bar{e}}$' at the center of their life as a means for gods' blessing. Aristotle understand '$schol{\bar{e}}$' as free activities and the completion of individual life. For Aristotle play is not only a freedom from labour but also a supreme activity. Play itself is an end and a completion. Play is the essence of human life so man can be happy with play. Play is the activity of joy. And play is the most intellectual and spontaneous activity. Now we can assert that '$heort{\bar{e}}$' is the original play which elucidate the existence of the human being in connection with world and is the holy mode of play which makes an affluent life of communities. And we can maintain that '$schol{\bar{e}}$' is a mode of play which freed from the burden of labour and elevate the life of human being to academic activities and contemplative life. By this interpretation we can expose that play is the center of life. We can see the two fold meaning of apollonian-dionysian play and the perfect harmony of communities in Plato's '$heort{\bar{e}}$'. We can see also the delight as splendidness of life in Aristotle's '$schol{\bar{e}}$'. The Plato's theory of play seems different from Aristotle's. But their theories are the same in the general, because they both put play at the center of life and they equally assert that we have to live with playing our life. The world in which play is in harmony with labour- this world is their utopia.

The purpose of this study was to find out the feature of children's play according to a player number restriction rule in the free choice activities. And it is expected that the result of this study will contribute to improving the management of free choice activities. The participants of this study were a homeroom teacher, professor as a co-researcher and 25 4-year-old children of a private kindergarten. The data were collected by observation, children interview and reflective journal of the teacher from July to October in 2014. The results indicated that the children were stressed out with using name cards for presenting center selection, showed overcompetitive behaviors, and frequently violated the rules. The researchers found that the restriction rule had some dysfunctions, which were interferences of moral development, social-emotional development, self-regulation development, preventing safety-accident and free choice behavior. The researcher as a teacher abandoned the player number restriction rule, and observed the children's play. As a result, children's self-regulation abilities on physical space, play and conflicts improved and the teacher changed her strategy when managing free choice activities. Based on the results, the needs of various restriction rules and appropriate methods for applying the rules in free choice activities were further discussed.

Objective: The purpose of this study is to examine the factors influencing the health status of first-year high school students leisure activity time, considering of the city size. Methods: This study utilized the first cohort survey of the Korean Children and Youth Panel Survey. The analysis was used data from survey targeting first-year high school students of 2021. The city size was divided into large cities and medium and small-sized cities, and T-test was conducted to examine differences in factors by city size, and multiple regression analysis was conducted to identify factors influencing health status according to leisure activity time on weekdays and weekends by city size. Results: In large cities, exercise and physical activity time and other than that, Time to play with friends had a positive effect(+), Time to play with a smartphone had a negative effect(-) on both weekdays and weekends. In medium and small-sized cities, Exercise and physical activity time and Time to play while watching TV had a positive influence(+) on both weekdays and weekends, while Time to play with a smartphone had a negative influence(-). Conclusion: There were the same questions for factors influencing health status, but other questions also appeared. Leisure activities that have a positive(+) impact on health status by city size are supported so that leisure activities can be actively carried out, while leisure activities that have a negative(-) impact are participate in other leisure activities together to improve health. It is believed that this plan should be considered.

The purpose of this research is to rethink Alvar Aalto's architecture on the basis of the aesthetic concept of play. This attempt is valid because he had asserted the importance of play in his design. But more fundamentally, his critical view of the instrumentalised rationalism implied the idea that a human being is "Man the Player" as well as "Man the Thinker", of which theory was elaborated in Johan Huizinga's Homo Ludens (1938). Premised on it, this paper investigated the evolution of the play idea in aesthetics and located Aalto's concept within the map. Summing up, his play was an intuitively grasped desire opposed to a rational requirement, which leads to a dialectical synthesis. This schema is similar to that of Schiller, in which Spiel reconciles the reason and the sense. However, Aalto's play could be differentiated into the "astonishingly rational" and "a jest", each of which roughly corresponds to the Spieltrieb (play impulse) and the sinnliche Trieb (sensuous impulse) in Schiller's thinking. On the other hand, Aalto's architecture illustrates play that could be interpreted as the overflow of surplus energy. This play is the very concept that can bridge the gap in the form-function formula of modern architecture. Aalto's play idea seemed to basically originate from his personality but its value must be confirmed by the Finnish litterateur Yrjo Hirn as Aalto mentioned in his statements (1953 & 1972). It appears that Aalto's play concept was materialised in architecture through his typical design language, such as the undulating wall, the aperspective space, the imitation of nature and the collage of heterogenous elements. However, we should be careful not to reductively analyse the application of play in practise. As Huizinga's comprehensive theory suggests, the play element exists in any cultural areas including any architectural activities. In conclusion, this paper argues that Alvar Aalto the Homo Ludens presented the possibility of critical rationalism in modern architecture by imbuing dry modernism with "the life enhancing charm" of "the art of play".

The objective of this study is to analyze teachers' experience in the operation of outdoor play in an early childhood educational institute. For this purpose, the experience obtained in planning/operating the outdoor play in early childhood educational institutes, as well as the difficulties experienced in their operational process, were examined. The data was collected through interviews with eight early childhood teachers. In the results of the study, first, the teachers' perception of outdoor play was analyzed. The teachers considered outdoor play as meaningful in that the children could develop gross/fine-motor skills, have the chance to develop their sociality, relieve their stress, and also commune with nature through outdoor play. Second, regarding the plan/operation of the outdoor play activities, even though they aimed to provide the children with meaningful outdoor play activities through various materials and methods, most of the teachers could not put their original plans into practice, because of the numerous variables in the actual site. The teachers' difficulties included insufficient time, spatial limitations, and insufficient qualifications for play instruction.

The purpose of this study is to help create environments for early childhood education according to the principles of Constructivism. Generally, preschools in Ulsan Metropolitan City were used as samples for this study More particularly, 116 kindergartens were surveyed by telephone to evaluate their education programs. Four kindergartens that completely or partially used Constructivism in their programs were chosen as primary subjects for this study The results of this study were as follows: First, it was discovered that preschool education in Ulsan uses an integrated education model based on activities and Montessorie. Constructivist programs were also present using Project Approach, Reggio Emilia and Piaget. Second, the number of infants per class averaged 29.3. The average infants per playroom was 2.38$m^2$. It seems, therefore, that there is a lack of sufficient space for activities. Playroom furniture is primarily used for storage and it lacks variety and flexibility of use. The interior of preschools in related to materials, color and images also showed little difference among schools. Third, it was found that virtually every play space did not have adequate water playing and sand playing sections. Instead, the space for the large-muscle activities of big groups was used for this purpose. Fourth, kindergartens that use the principles of Constructivism plan to specialize their activities. Those only partially using Constructivism showed conventional tendencies and small play spaces that would be defined as inadequate according to Constructivism. This study, therefore, demonstrates that preschool education based on Constructivism are not being well-implemented in concert with other programs.

The purpose of this study is to classify playground types according to the physical characteristics of playgrounds in child care facilities, to analyze the needs of care-givers and to evaluate the adequacy of playgrounds according to playground types. The specific areas discussed in this study were the evaluation of the adequacy in the physical characteristics of playgrounds for children's outdoor play activities by the care-givers, who assist in the outdoor play activities of children and manage safety in the playground, and a report on playground requirements of them. Data was collected from field survey carried out to investigate the physical characteristics of playgrounds of 21 child care facilities. This survey incorporated a structured-questionnaire for the purpose of evaluating the adequacy of the physical characteristics of playgrounds (location and size of the playground, play equipments, the composition of play areas, ground covers, and location of sidewalk in the playground) by the 181 care-givers from the facilities and investigating the needs of them. The major results showed the following. 1) In field survey, it was observed that while the location and the size of the playgrounds varied widely, ground cover, play equipments, and the composition of play area turned out to be identical, regardless of the location and the size of the playgrounds. 2) The playgrounds were classified into five types according to the number of children and the size of the playground. The five types include A-type as a large-scale facility/smallsize playground, B-type as a small-scale facility/large-size playground, C-type as a small-scale facility/small-size playground, D-type as a middle-scale facility/large-size playground, and E-type as a large-scale facility/large-size playground. 3) The adequacy of the physical characteristics of playground in the D-type was evaluated to be higher than that of the other types. The adequacy of the C-type playground was evaluated to be lower than that of the other types in terms of size and the composition of play areas within the playground. 4) The care-givers of the D-type and the E-type playground expressed a desire to install various play equipments, while the care-givers of the C-type playground did not wish to install play equipment. 5) Various outdoor play areas were needed in the D-type playground.

In order to figure out the relationships between structural features and biological activity of the host-specific HC-toxin in maize, structurally related cyclic tetrapeptides, chlamydocin and CYL-2 were isolated, and their biological activities in maize were examined. Biological activities of preparations were determined by root growth inhibition and electrolyte leakage bioassays. Chlamydocin and CYL-2 showed toxicities to maize. However, the toxicities of these compounds were non-specific. Thus, the precise peptide ring structure of HC-toxin apparently does not play an important role in toxicity, while resistance of maize to HC-toxin is based on a precise ring conformation.
