we proposed the use of $Si_2H_ 6/H_2$ chemistry for selective silicon epitaxy growth by low-pressure chemical vapor deposition(LPCVD) in the temperature range $600~710^{\circ}C$ under an ultraclean environment. As a result of ultraclean processing, an incubation period of Si deposition only on $SiO_2$ was found, and low temperature epitaxy selective deposition on Si was achieved without addition of HCI. Total gas flow rate and deposition pressure were 16.6sccm and 3.5mtorr, respectively. In this condition, we selectively obtained high-quality epitaxial Si layers of the 350~1050$\AA$ thickness. In older to extend the selectivity, we kept high pressure $H_2$ environment without $Si_2H_6$ gas for few minutes after first incubation period and then we conformed the existence of second incubation period.

Objectives : This study investigated the influence of traumatic experience on the ego identity, self-esteem, and general psychopathology of adolescent North Korean refugees. Methods : The participants were 146 adolescents North Korean refugees who attended H High School for North Korean refugees. We divided the subjects into two groups according to the severity of their traumatic experience : the more-traumatic-experience group and the less-traumatic-experience group. Each group performed self-report assessments including an assessment to reveal demographic characteristics, the Traumatic Experiences Scale for North Korean Defectors, the Scale for Ego identity, the Scale for Self-esteem and the Symptom Check-90-Revision (SCL-90-R). Statistical analysis of t-test and multiple regression utilized SPSS 12.0 for Window for comparison between more-traumatic-experience group and less-traumatic-experience group. Results : The prevalence of posttraumatic stress disorder among adolescents North Korean refugees was 37%. The factor with the greatest influence on ego identity was length of time living in South Korea, while, for self-esteem the most influential factor was perception of health. The more-traumatic-experience group had lower self-esteem scores on some subscales of the Scale for Ego identity. They had higher scores on all SCL-90-R subscales than the less-traumatic-experience group. Conclusion : Adolescent North Korean refugees experienced high rates of posttraumatic stress disorder. The more traumatic-experience-group had lower self esteem and poorer ego identity and mental health than the less-traumatic-experience group.

손용훈 ( Yong Hoon Son ),함광민 ( Kwang Min Ham ) 한국전통조경학회(구 한국정원학회) 2011 한국전통조경학회지 Vol.29 No.3

본 연구의 목적은 사의적 대상에 대한 해석방법으로서 의경(意境) 개념을 사용하여 창덕궁 후원의 경관 특성을 해석하는 것이다. 의경에서 경(境)은 경계를 의미하며, 사물을 인식하는 범주이다. 사의적 대상에 관한 인식의 범주는 감정적인 면을 대상으로 하는 정경이 있으며, 이보다 확대되어 진리 혹은 이상의 정신적 대상을 포함하는 의경의 단계가 있다. 본 연구에서는 의경의 구조를 분석 틀로 하였으며, 조영 주체인 왕의 행적과 고전을 중심으로 창덕궁 후원의 의경과 경관 특성을 명확히 하였다. 연구결과, 창덕궁 후원 조영에 있어서 인조, 숙종, 정조 세 왕이 깊게 관여되어 있음을 알 수 있었다, 인조는 후원 조영의 물리적 기반을 닦았고, 숙종은 상림십경(上林十景)을 통해 후원의 정경을 향유하였으며, 정조는 학식과 정치적 비전에 관한 뜻을 후원에 투영하여 의경의 범주를 넓혔다. 의경 개념은 정신적 대상의 범주를 체계화하고 이해하는데 유용한 사고방법으로, 형태보다 정신적 대상을 중시한 우리나라 전통조경의 효과적인 해석 방법론이라 하겠다. The purpose of this study is to interpret the landscape characteristics of Changdeokgung`s rear garden with the idea of Yijing(意境) the way to have a sense of an imaginative object. A teim of Jing(境) in Yi-jing means a boundary of man`s consciousness. On the boundary of consciousness for an imaginative object, there is a situation of man`s emotion to be called Qingjing(情境) to meet an object, and beyond Qingjing, there is Yijing, a consciousness of the idea and the truth. The Structure of the Yijing is an analytical framework in this study. It is clarified that the idea of Yijing and landscape characteristics of changdeokgung`s rear garden to analyze works of kings and related historical documents. In result, there were three kings named Injo, Sukjeong and Jeongjo who played big roles to develop the rear garden. First, Injo had built physical structure of the rear garden, the second Sukjong enjoyed Qingjing with composing the poems of Sangrimshipkyoung(上林十景), Jeongjo clearly had made a boundary of idea of Yijing broaden. It is an effective way to interpret imaginative characteristics of our traditional landscape through the concept of Yijing the useful way to understand and systemize a subject of idealistic consciousness.

1917년 경성부 남산공원설계안의 삼림공원 개념에 관한 연구

손용훈 ( Yong Hoon Son ),서영애 ( Young Ai Seo ) 한국전통조경학회 2012 한국전통조경학회지 Vol.30 No.4

본 연구의 목적은 1917년 수립된 ``경성부 남산공원설계안’의 내용을 분석하여 설계안의 특성과 의의, 그리고 삼림공원의 개념을 고찰하는 것이다. ‘경성부 남산공원설계안’은 남산을 대상으로 하여 전문적인 공원계획가에 의해 처음 시도된 공원계획이다. 설계안을 수립한 공원계획가는 일본의 근대 도시공원 선구자인 혼다 세로쿠다. 그는 남산공원 계획시 삼림공원으로서의 계획개념을 명확히 했다. 이를 통해 당시 경성에 있어서 남산이 갖는 공간적 위상을 고찰할 수 있다. 계획된 남산공원의 공간범위는 당시 존재하던 왜성대공원, 한양공원, 노인정, 장충단 등 남산의 북측 공간이 넓게 포함되었고, 남측으로는 성벽을 넘어 용산으로 연결하는 등 매우 넓게 검토되었다. 이러한 넓은 공간적 계획범위를 대상으로 공원도로계획, 공원시설계획이 수립되었고, 각각 도입되는 시설과 이를 관리하기 위한 공원경영방법이 함께 구상되었다. 비록 혼다의 남산공원계획안은 실행되지 못했지만, 남산을 대상으로 하여 최초로 수립된 근대적 공원계획안이라는 점에서 의의가 있다. 더불어 계획안이 갖는 현대적 의미와 시사점도 함께 고찰했다. The purpose of this study is to analyze features and meanings on Kyonsungbu Namsan Park Design Proposal established in 1917, and to discuss the significance of the idea of Forest Park on Namsan Park. This Namsan Park Design Proposal has been the first attempt to apply modern park concept to broaden Namsan area by a professional park planner. The professional park planner to conduct Namsan Park Design Proposal is Dr. Seiroku Honda who is a pioneer of modern Japanese park planning. He clarified the concept of Namsan Park into Forest Park. With his idea we can imaginethe position of Namsan at that time as a meaningful green space in Kyonsung city. In the proposal, the planning boundary of Namsan Park was considered widely as Namsan area into one big park, including the north with existing Wesungdae Park, Hanyang Park, Noinjeong and Jangchungdan, and the south with connecting park to Yongsan area beyond the walls of Hangyang castle. In a wide range of park space of the plan, parkways and park facilities were introduced. How to manage new parkways and facilities were also considered together. The significance of this plan is that it is the first trial of modern park planning with Namsan. In addition to the analysis of Kyonsungbu Namsan Park Design Proposal, the modern meaning and implications were also discussed.

The purpose of this study is to survey on parents`` preference and estimate parents`` Willingness to pay(WTP) for after-school rural experience program in daegu city by choice experiment(CE). The results of this study are as follows; First, we divided after-school rural experience program into three types, namely: nature seeing, play exercise and learning experience. Second, the study has shown that parents prefer learning experience among those after-school rural experience programs. Among attributes which form a experience program, instructor certificates, consuming time and expense for participant are statistically effecting significant impact. Third, the result of estimation on willingness to pay for development of after-school rural experience program is as follow. The willingness to pay for learning experience is 6,337won, willingness to pay for instructor certificates is 14,102won and it for consuming time is 2,926won. Therefore, composition centering learning experience is better and instructor who has expert certificate is required. It is much better to compose that the consuming time is longer and the expense for experience is lower. But there is limitation because this survey was conducted based on an assumption, so it could read over estimation problem. The result of this study may provide useful information to develop after-school rural experience program using rural resources and to improve rural tourism policy.

공장입지에 따른 대도시 근교지역 농촌마을의 경관변화 특징

손용훈 ( Yong Hoon Son ),이차희 ( Cha Hee Lee ),사이토유키히코 ( Yu Ki Hi Ko Saito ) 한국농촌계획학회 2014 농촌계획 Vol.20 No.1

The purpose of this study is to identify characteristics of the landscape changes in Gwangjyu city and Icheon city, the suburban areas on the outskirts of the Seoul metropolitan area, by focusing on the causes of the urban sprawl and the resultant morphological characteristics of landscape degradation. Particular attention has been given to the ‘advantages for developing suburb including geographical proximity and land price’, ‘institutional regulation such as land-use regulation’ and ‘community solidarity’ as drivers for possible introduction of external factors. The types of landscape change were divided into three, after having on-the-ground research on eleven chosen towns and interviews with head of a village: Overwhelming Change, Separated and Small-Scale Change. It was found that, in general, the quality of landscape was best for the small-scale change type, followed by separated and overwhelming change types. While the types of landscape change are correlated with the geographical proximity, its relevance with land regulation is relatively weak. The study found that imposing a land-use regulation as a means to prevent changes in suburban village landscape may not be fully effective. Also it analyzed that villages could better manage with keen interest the surrounding landscape if there is a high degree of solidarity within the village community. Therefore, the sense of community could play an important complementary role to land-use regulation which does not suffice in itself to manage suburban landscape.

This study intended for Cheongryongsan Community Garden in Gwanak-gu, one of the demonstration places for ‘Community Garden’ Project recently implemented by the Seoul Government. This study had two major purposes: investigating the current status of the management and usage and identifying its characteristics; investigating users` awareness to consider the construction and operation directions of sustainable community gardens. This study was conducted based on several surveys such as an investigation into the spatial configuration and the management system of parks through a field study, a use survey through a questionnaire survey for vegetable garden users and an awareness survey about the construction direction of gardens direction preferred by users through the analytical hierarchy process (AHP). As a result of a questionnaire survey for vegetable garden users, the usage status was summarized as follows: Considering the common trends in the 2012 and the 2013 user survey, women used Cheongryongsan Vegetable Garden more than men. Over fifties used it most of all users. Users were mostly neighborhood residents. They used to visit there three to five times a week and stayed for about 30 minutes to one hour. Users differently responded to the question related to the order of priority for the use of the garden in the 2012 and the 2013 survey. They had increasingly used it for individuals` production activities more than social exchanges. As a result of making an AHP analysis for general park users, vegetable garden users there were clear differences in the targets which each subject put emphasis on in relation to the construction and operation of vegetable gardens. General park users recognized a vegetable garden as a park where park functions and the functions of the vegetable garden coexisted. On the other hand, vegetable garden users viewed it as a space where they attached importance to the functions of the vegetable garden like an allotment. Last, this study contemplated subjects related to the construction and operation of vegetable gardens which had to be considered in the future. Vegetable gardens tended to be biased as personal hobby places. It was viewed that the main reason was insufficient support activities for vegetable garden education and exchange programs originally planned when vegetable gardens had been constructed. Vegetable garden users recognized vegetable gardens as places for individuals` farming activities like allotments. For the desirable operation of vegetable gardens, it would be necessary to give priority to the park management before the production activities in individuals` vegetable gardens. The important role of the government would be to build the base through the provision of education and opportunities so that a local resident organization could actively participate in the management of a vegetable garden after a vegetable garden was constructed. It would be necessary to make a use survey and an awareness survey for users conducted in this study on a regular basis because the surveys could be important basic data in the decision-making process for the sustainable operations of the vegetable garden.

BIM에 관한 조경분야의 동향 및 LIM 활성화 방안

김복영,손용훈,Kim, Bok-Young,Son, Yong-Hoon 한국조경학회 2014 韓國造景學會誌 Vol.42 No.3

2000년대 초 건설분야에서 BIM은 생산성 향상을 목적으로 도입되어 각국 정부정책의 지원에 힘입어 세계적으로 사용이 급증하고 있다. 조경분야에서는 미국 ASLA에서 BIM 도입에 관한 논의가 처음 진행된 이후, 유럽을 중심으로 연구가 확산되고 있고, 영국, 노르웨이 등은 이미 조직적인 활동을 수행하고 있다. 반면, 국내 조경분야에서 관련 연구는 매우 드물며, 현업의 BIM 적용에는 많은 어려움이 있다. 이에 본 연구에서는 해외 조경분야의 BIM 도입 동향을 파악하고, 국내 조경분야의 활성화 방안을 도출하고자 하였다. 연구 결과, 건축정보모델링을 의미하는 BIM이 조경분야에서 새로이 조경정보모델링을 의미하는 LIM(Landscape Information Modeling)이라는 용어로 통용되는 추세임을 확인했다. 또한 LIM의 활성화를 위해 조경정보의 통합과 재활용을 위한 정보 표준화와 호환성 확보 문제를 해결해야 하는데, 이를 위해 BIM의 정보표준인 IFC를 조경업에 맞추어 확대하려는 활동이 이루어지고 있고, BIM과 GIS 연계를 통한 통합정보를 구축하는 연구도 이루어지고 있음을 확인했다. 특히 영국과 노르웨이 조경협회는 working group들을 조직하여 조경분야에서의 BIM 도입을 선도하고 있는데, 이는 국내 조경분야의 LIM 활성화 방안을 수립하는데 유용한 참고사례가 된다. 따라서 연구의 고찰로서 이들 국가의 조경협회에서 수행하는 사업을 정리하여 국내 조경분야의 LIM 활성화에 필요한 4가지 방안을 제시하였다. Since the new millennium, BIM has been widely adopted to improve productivity in the field of architecture, engineering, and construction with the government policies of each country. After its first introduction into the field of landscape architecture in USA, BIM has been debated on its merits and limitations mainly by the European countries' academic and, at the same time, practical worlds. However, little attention has been paid to BIM, in particular, in the field of landscape architecture in Korea leaving many issues to solve to fully utilize BIM. The purpose of this study is to present the main issues and strategic agenda for the successful introduction of BIM in landscape architecture in Korea. This study shows that the new derived word of LIM(Landscape Information Modeling) instead of BIM appeared in the field of landscape architecture. Then, this paper discusses the main issues on standardization and interoperability in the adoption of LIM to create, integrate, and reuse landscape information. Finally, four strategic agenda are presented to successfully introduce LIM into the domestic field of landscape architecture by reviewing the societies of the landscape discipline in UK and Norway that play a leading role by organizing BIM working groups.
