The direction of Urban regeneration is changing toward holistic regeneration with residents' participation all over the world. While world leading projects in holistic regeneration such as "Ballymun of Ireland" and "Buffalo of U.S.A" appeared, recently in Korea, "Rainbow project" is getting paid attention as a similar example due to its Socio-Physical approach. The purpose of this study is to find the Effect of Socio-Physical Regeneration on Social Network characteristics of Elderly Residents in a public rental apartment. The subjects of the study are elderly residents who have resided since much before the environmental intervention. The research methods is in-depth interview. Specific features of social network included awareness of the physically improved surrounding environment, awareness of and participation in welfare programs, social interactions, identity, and vandalism behavior. As results, most of elderly residents recognized environmental improvement and felt very positive enough to enhance their attachment and pride in their residences. Physical environment changes had a considerable impact on the social network characteristics and also had a strong influence on their relations with community. Considering that permanent public rental housing has been a socially isolated place, it is significant to notice that residents' perception of being excluded and behaviors are changed gradually being influenced by environmental improvement.

In the 20th Century, urban regeneration was changed to holistic regeneration and Ballymun of Ireland was one of the example of leading projects which using holistic regeneration over ten years. In Deajeon, there is a successful project call as "Rainbow project", using holistic regeneration. Any previous case needs to be checked thoroughly and the result needs to be studied for next project. The purpose of this study was to delineate the effect of Socio-Physical regeneration on social network. For this research, research tool was developed to combination of previous social exclusion index. This research was a survey research which used Systematic Random Sampling. In conclusion, it was not enough time to change people's behavior dramatically but even though a change is very low, it is very meaningful. Changing from people's behavior to people's mind, is a step to a goal.

본 연구는 농약류에 대하여 구조-활성의 정량적 관계(QSAR)를 이용하여 무지개 송어(학명: Oncorhynchus mykiss)의 급성 독성을 예측-분석하는 과정을 수행하였다. 모델 구현을 위해 사용된 275종의 농약류에 대한 수중 독성(96h $LC_{50}$) 값은 DEMETRA프로젝트의 데이터를 사용하였다. 예측 모델에 사용된 2차원 분자 표현자는 PreADMET프로그램으로부터 계산을 하였고, 선형 (다중 선형 회귀 방법)모델과 비선형(서포트 벡터 머신, 인공 신경망) 학습 방법들은 실험값과 예측값의 적합도를 고려하여 최적화 되었다. 데이터 전처리 과정을 거친 뒤에, 5묶음 교차 검증과정을 포함한 모집단 기반 전진 선택법을 통해서 각 학습 방법의 최적의 표현자 집합을 결정하였다. 가장 좋은 결과는 SVM 방법 ($R^2_{CV}$=0.677, RMSECV=0.887, MSECV=0.674) 이었고, EU의 규제 기준에 따른 분류에서는 87%의 정확도를 나타내었다. MLR방법을 통해서는 무지개 송어의 급성 독성에 대하여 독성을 나타내는 농약류의 구조적 특징과 지질 층과의 상호작용을 설명할 수 있었다. 개발된 모든 모델들은 5묶음 교차 검증과 Y-scrambling test을 통해 검증되었다.

The Danish-Icelandic artist, Olafur Eliasson who was born in 1967 is known for installation projects employing materials such as colour, fog, mirror and light to rethink the relationship between human and surrounding. Since he started the early projects, Eliasson has been interested in the relationship between an art, a viewer and space. He has used the medium from nature because he thought nature is very common subject to derive new idea of relationship between human and surrounding. Eliasson revealed the idea of relationship between human and surrounding by three characteristics of spatial design such as 'reinterpretation of placeness by juxtaposition of mediums and defamilarization', 'ambiguity and extensity of depth distance of space by mediums' and 'change in spatiality by movement of viewers and time'. This paper focused on four case projects : The mediated motion in 2001, The weather project in 2003, The blind pavilion in 2003, Your rainbow panorama in 2011. It is aimed to discover relationship between human and surrounding in the case projects under three characteristics. This study found that three characteristics were differently applied in the case projects in terms of spatial experience and design methods. Inside & outside locations, formal quality, visual-perceptual relationships in and around each case are crucial elements and tools. The unique relationship between human and surrounding of Eliasson and three characteristics are applicable to architecture and spatial design.
