There have been many requests for development of senior housing in Korea. Therefore it was very important to review how senior houses are established and managed in other countries. In this point, this research compared the actual conditions of the homes for the elderly in the U.K, U.S.A and Japan. Through the process, this research aimed to find the implications for Korea. The research was conducted by the literature review on senior congregate housing with Franklin's(1998) social constructionism perspective. This kind of research might be utilized as a theoretical framework for performance of any systems of housing for the aged. In this study, the researchers suggested the implications of senior congregate housing as follows. Firstly, in terms of structural context, government in the U.K, U.S.A., and Japan were positively concerned with solving the housing problems for senior citizens despite some differences. Secondly, from an institutional context, institutions related with provision, construction, and management of senior congregate housing were systematically consolidated and they all adapted the housing and welfare policy. Thirdly, in organizational context, there was an organization in charge of provision and management that exclusively oversaw the housing for the elderly in both the public and private sectors. Fourthly, in operational context, standards regarding space were clearly set both for individual units and common spaces as well as for facilities and services for the residents. Finally in terms of intersubjective context, the competency of housing manager and ways to involve the families which were important for residents' independent life were under study.

With a shift in the rural development process toward a bottom-up approach, the need to enhance the endogenous capacity of communities has become the core of rural development. In this regard, scholars have paid close attention to social capital to identify ways to facilitate endogenous rural development but focused mainly on relationships between social capital and local environment. That is, few studies have investigated the relationships between social capital and its various dimensions in the context of rural development initiatives. This study examines the effects of social capital on the problem-solving ability of community residents'rural development initiatives and assesses the types of social capital associated with such initiatives to propose optimal path for improving this ability. To distinguish between major dimensions of social capital, a questionnaire was developed by considering various stages of the rural development process. The survey considered a sample of 59 employees from public rural development institutions. According to the results, four paths were significant at the 5% level. Among these four paths, three set common goals. The effective channel was the path [common goals${\Rightarrow}$network${\Rightarrow}$cooperation${\Rightarrow}$problem-solving ability]. The key factor in improving problem-solving skills, the endogenous ability of community residents to facilitate rural development initiatives. The results suggest that governments should strengthen education and training programs to help residents set their common goals.

Significant changes in the past year have taken place in the world of work that are bringing new challenges with regard to employee safety and health. These changes have led to emerging psychosocial risks (PSRs) at work. The risks are primarily linked to how work is designed, organized, and managed, and to the economic and social frame of work. These factors have increased the level of work-related stress and can lead to serious deterioration in mental and physical health. In tackling PSRs, the European labor inspectorates can have an important role by enforcing preventive and/or corrective interventions in the content and context of work. However, to improve working conditions, unilateral interventions in the context and content of work are insufficient and require adopting a common strategy to tackle PSRs, based on a holistic approach. The implementation of a common strategy by the European Labor Inspectorate for tackling PSRs is restricted by the lack of a common legislative frame with regard to PSR evaluation and management, the different levels of labor inspectors' training, and the different levels of employees' and employers' health and safety culture.

Four science concepts were selected from high school earth science textbook to investigate the differences in students knowledges activated in laboratory and earth environmemtal contexts. Two items, one is for laboratory and the other for earth environmental contexts, were develped for each selected concept. Students' responses were analyzed in terms of 'Common Activated Knowledges' (CAK), 'Specific Activated Knowledges'(SAK) across students' cognitive frames, grades and sexes. As contextual differences of the problems increased, gender contributed more than other variables to the frequencies of activating CAK and SAK. Context effects were also reported across cognitive frames for CAK, but SAK became more avtivated when the contextual differences of the items become smaller. As a whole, students with laboratory cognitive frames showed more significant context effects than others. Students in 11th grade, with scientific frames and with earth science cognitive frames showed relatively small context effects. The results of the study showed that sciene concepts learned in a laboratory context are not usually transferred spontaneously to earth environmental contexts. Special instructional strategies should developed to overcome the context effects.

The object of this study is upper class house in Yang-dong village with the purpose of spatial-sociological study of traditional Korean architecture. Space is the basic element of architecture and is fundamental for understanding architecture. Space, however, can be better understood through its social context rather than through its physical or psychological attributes. Space exists in a society, providing the physical environment which frames it Social environment affects the thoght of people who are members of that society. Space is built by the people in a society and is affected by their thought. Spatial-sociological study can explain a mutual relation between people and space through context. It defines characteristics of space based on mutual relations which exist among the people, the culture of society and the environment of society but also having a sociological component, study of architectural space should consider the social context. Since architectural space is built on social and cultural bases, to understand it requires various methods of study Spatial-sociological analysis is one alternative. Using space syntax, this study analyzes houses in Yang-dong village by not only defining attributes of individual houses, but also common attributes of houses in the village. Based on common attributes of houses in the village, the attributes of Yang-dong village houses can be re-defined within the social context. the results from a spatial-sociological analysis of upper class housing of the Yang-dong village are as follows; (1) Related to confucian ideas in Chosun Dynasty : A house has a dualistic center organized with 'an-chae' and 'sarang-chae'. 'an-chae' space is organized unsociably from outside. (2) Related to various space pattern of Yang-dong village House in the Chosun Dynasty period :As variations in the types of space pattern, the village house exhibit different attributes.

This study examined preschoolers' compliance and noncompliance as it related to maternal behavior, child gender and age, and social context. The subjects were 213 preschool children in Seoul. Data were collected via questionnaires reported by mothers and teachers. The results of correlation analysis and a series of repeated measures ANOVA revealed that mothers' coercive parenting was associated with lower committed compliance and ignorant noncompliance. It was also found that the 5-year-olds studies showed higher committed compliance in moral situations whereas the 6-year-olds showed higher situational compliance in conventional situations. Noncompliance was more common among the 5-year-olds than the 6-year-olds. It was also found that girls exhibited higher compliance than boys in both moral and conventional contexts. The results were discussed in terms of a developmental perspective.
