This study was initiated by the fact that modern architecture caused the loss of placeness by seeing place with wrong interpretation and method and provided people with a phenonenon of separation between the depth of experience and honesty. As a solution for such problems, this study intended to suggest a direction through an analysis on the works of Geoffrey Bawa who was recognized as 'a genius of place' and the investigation on the place characteristics of his representative work 'Lunuganga'. Its process was as follows; First, this study explored the characteristics of the place, Sri Lanka, which was the background of his architectures, to see its impact on his life and architecture. Second, based on his representative works of each period and the contents that he mentioned in literature, the general characteristics appearing in his architectures were identified. Third, through an analysis on the work, Lunuganga, the place characteristics appearing in his architectures were investigated. Through such process, it could be recognized that Geoffrey Bawa's architectures reveal the place characteristics as nature, place characteristic as journey and stay, and place characteristic as sense. In this study, it could be verified that place was integrated and applied to Geoffrey Bawa's architectures through the above characteristics and the spaceness was manifested. Through this, this study intended to suggest an orientation for the above problems.

The application of software engineering is not common in the development of astronomical observation system. While there were component-wise developments in the past, large-scale comprehensive system developments are more common in these days. In this study, current methodologies of development are reviewed to select a proper one for the development of astronomical observation system and the result of the application is presented. As the subject of this study, a project of operation software development for an astronomical observation system which runs on the ground is selected. And the output management technique based on Component Based Development which is one of the relatively recent methodologies has been applied. Since the nature of the system requires lots of arithmetic algorithms and it has great impact on the overall performance of the entire system, a prototype model is developed to verify major functions and performance. Consequently, it was possible to verify the compliance with the product requirements through the requirement tracing table and also it was possible to keep to the schedule. Besides, it was suggested that a few improvements could be possible based on the experience of the application of conventional output management technique. This study is the first application of the software development methodology in the domestic astronomical observation system area. The process and results of this study would contribute to the investigation for a more appropriate methodology in the area of similar system development.

Objective : Metaplastic meningioma is an extremely rare subtype of World Health Organization (WHO) grade I meningioma. It has distinctive histological subtypes according to its own mesenchymal components. Owing to its scarcity, clinical or radiological features of a metaplastic meningioma are poorly described. Methods : Between 2004 and 2018, we analyzed total 1814 cases surgically proven meningioma for 15 years. Among them, metaplastic meningioma was diagnosed in 11 cases. Magnetic resonance images were taken for all patients, and computed tomography scan was taken for 10 patients. Results : WHO grade I meningiomas were 1376 cases (75.9%), 354 cases (19.5%) in WHO grade II, and 84 cases (4.6%) in WHO grade III meningiomas. Metaplastic meningioma was 11 cases as 0.8% of WHO grade I meningioma and 0.6% of entire meningiomas for 15 years. Among the entire 11 metaplastic meningiomas, five tumors (45%) were diagnosed as a lipomatous subtype with rich fat components, four (36%) as an osseous subtype with extensive bone formation and two (18%) as a xanthomatous subtype. There was no cartilaginous subtype metaplastic meningioma in our study. Lipomatous and osseous metaplastic meningioma have peculiar radiological characteristics according to mesenchymal components. Conclusion : We investigated a rare metaplastic meningioma subtype based on our 15-year surgical experience with meningiomas. Further investigation will be necessary for the clear clarification of tumor nature of this rare tumor.

This study researches attributes , behaviors , satisfaction factors and degrees of curiosity of visitors to recreational forests in the suburbs of a large city. It aims to present suggestions for urban forest development and management policy by offering basic data which help to plan, design and manage recreational forests to increase the quality of these environments. The results are as follows First, in attribute, the visiting rate of males is higher than that of females, and the main users are in their thirties and forties. Sixty percent of visitors graduated from university and their rate of employment is evenly distributed. 95 percent of visitors are residents of the metropolitan area. In terms of behavior, major visitors are family units visiting during summer seasons and for overnight stays. 75% are re-visitors. 85% of visitors came to escape the city with families and friends, keep in good health and experience nature. Second, to extract the factors affecting visitor satisfaction in recreational forests, the natural environment, facilities, and management/use systems were identified as independent variables, while subordinate satisfactions were dependent variables. so regression analysis was used. Thus, the variables affecting the natural environment are quality of water, stream use, biodiversity, fresh air and landscape factors. The variables affecting facilities are puking, convenience, play facilities, sanitary arrangement and camping. Most important among the variables affecting management/use systems are educational facilities and access condition. On the basis of generalizing the study in the existing individual site, we must verify the visiting characteristics in recreational forests in the suburbs of a large city. Since development of recreational forests is understood as a sequence considering a site and a given condition, and since management and improvement must unfold according to these characteristics, a strategy is needed to reveal visitors' opinions about the site. Depending on the facilities and service, satisfaction of recreational forests is generally influenced by social and economic qualities. Also, this study can look into the effect according to use pattern motive and season. As suburban recreational forests have many overnight-users and younger men, programs suitable for these groups are needed. On the basis of variables affecting satisfaction according to natural environment, facilities, and use system, policies which can manage the natural environment and introduce educational programs are needed.

Maintaining our tradition makes us have pride for our nation and plays important role for recognition and establishment of identity for our unique culture in the world. Contrast to the western scientific technique, the scientific technique of Silla Bell absorbed in the life of our nation is the fruit of wisdom science found through rich life and experience by harmony between our nation and nature. Today, ideological backgrounds for many cultural heritages weren't be found and there are many overflowing hypothesis. Silla Bell is the plastic art including cumulative utopia of the racial spirit. So there would be the information of the racial spirit including symbolization, artistry, creativity, and historicity. However, unlikely with the words, it is the profoundly concentrated shape, so the meaning can be diluted or distorted in later generation. The efforts to figure out the symbolization in Korean bells, especially Silla bell according to its exclusive shape, but no hypothesis was accepted as an established theory of academia by gaining extensive agreements. Thus this paper traces the symbolic meaning accumulated in the shape and prepares for the theoretical background accessing to the artistic spirit of forebears who created super-humanity formativeness. Also regarding the Silla bell which is regarded as the best Buddhist metal craft that people believe they can be free from the anguish at the time of listening to its sound, we studied the symbolization of the bell as the religious ritual custom as well as the possibility to utilize the bell as a motif of living art in the aspect of formative expression.

Gwangju Metropolitan Government & Ministry of Environment have signed a model city in response to Climate Change agreement. The agreement calls for Gwangju to cut greenhouse gas emissions 10% below 2005 levels by 2015. Gwangju has seen this agreement as an opportunity to cut pollution and conserve the environment as well as to reinvigorate local economy. According to policy of Gwangju, Gwangju held design competition for Gwangju City Arboretum on march, 2009. The purpose of design competition was to give a wide publicity to Gwangju as Hub City of Asian Culture and construct carbon-neutral arboretum in accordance with the policy of 'Low-Carbon and Green Growth'. First of all, a design concept of arboretum is 'winding, round, overlay 'to reflect the landscape of Nam-do which is surrounded by mountains and river flows through the village. Second, the arboretum has five different places with these themes - Forest of Festivals, Health, Nature, Nostalgia, Education and Future. Each place has a symbolic theme park and different flow planning respectively. Third, the most critical point is that the arboretum is a carbon-neutral park. Gwangju arboretum will soon be developed in metropolitan sanitary landfill and constructed as the O2 arboretum based on low carbon strategy. Fourth, the O2 arboretum suggests specialized issue : 'Energy Saving', 'Recycling System', 'Green Network', 'Water System(rainwater maintenance and wetland development)'. Besides, main buildings(greenhouse, visitor center, Nam-do experience exhibition hall, and forest museum) is designed in consideration of harmony with topography character, surroundings. Also, planting will be a multilayer plant based on native landscape trees in consideration of function and the growth characteristics.

Environmental problem and eco-crisis don't mean pollution itself any more, although general people have believed that environmental problems can be resolves by removing pollution. The mos important is environmental problems are linked with social structure which individualism, rationalism is extremely prevailed in the market oriented capitalism society, so public value is ignored especially. In the point of environmental education, this is very important because environmental education is not completed through schooling process, such s class learning, discussion. observation etc, but in the our practical life itself. This means that environmental education can be done by changing of lifestyle anywhere we live, and anytime. But any places governed our social life are polluted by efficiency pursuiting individualism in market oriented capitalism society. So environmental education can't hold the water in this system, in the aspect that we can't stimulate feelings of the student and general people, getting to public resource value and harmony with nature by throwing individual mind away. It is big problem. In this field, I have thought the unique space and social structure which can be used as environmental education place is small-planning community, such as Kibbutz in Israel, educational community Finhorn in Scotland, harmony community Yamagicism Village in Japan and DURE in Korea etc. For the research of this educational possibility in these small community, I visited and investigated immediately, and confirmed. In this thesis, I insist that the training process and practical life experience in this community themselves are good environmental education. So, in case of YAMAGICISM in Japan and FINDHORN in Scotland, DONGSASUP program in Korea, I introduce these small community environmental- education program.

기체분자운동론에 관한 고등학생들의 개념 및 개념유형에 대하여 반구조화된 심층면담과 오디오${\cdot}$비디오 기록을 분석하여 고찰하였다. 학생들은 학교학습 이전에 이미 다양한 개념들을 가지며, 개념망의 조직화와 정교화수준에 따라 세 가지 개념유형 즉, 피상적 용어사용, 부분적 의미형성, 인과적 의미형성으로 구분되었다. 이러한 개념유형은 학생들이 과학에 대해 이해하고 사고하는 방식, 개인 개념의 안정성, 학교 지식과 일상적인 지식의 분리 경향, 그리고 맥락에 따른 의미형성에 영향을 주었다. 이것은 학생들의 과학적 지식의 본성에 대한 이해 부족과 학습에 대한 주체의식 및 능동적인 참여의 제한으로 인한 결과로 해석된다. 이는 과학적 의미형성을 위해서 학생의 사고의 가치가 인정되고, 적극적인 토론과 합의의 기회가 주어져야함을 시사한다.
