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.

The acute toxicity in the rainbow trout (Oncorhynchus mykiss) was analyzed and predicted using quantitative structure-activity relationships (QSAR). The aquatic toxicity, 96h $LC_{50}$ (median lethal concentration) of 275 organic pesticides, was obtained from EU-funded project DEMETRA. Prediction models were derived from 558 2D molecular descriptors, calculated in PreADMET. The linear (multiple linear regression) and nonlinear (support vector machine and artificial neural network) learning methods were optimized by taking into account the statistical parameters between the experimental and predicted p$LC_{50}$. After preprocessing, population based forward selection were used to select the best subsets of descriptors in the learning methods including 5-fold cross-validation procedure. The support vector machine model was used as the best model ($R^2_{CV}$=0.677, RMSECV=0.887, MSECV=0.674) and also correctly classified 87% for the training set according to EU regulation criteria. The MLR model could describe the structural characteristics of toxic chemicals and interaction with lipid membrane of fish. All the developed models were validated by 5 fold cross-validation and Y-scrambling test.

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.
