This study aims to examine the relationship between physical environment and depression symptoms of middle-aged and older adults in metro city. To verify correlates of community environment and depression, mediating effect model structured by social capital and sense of coherence(SOC) were used. For the purpose, a survey was conducted aged 48 - 70 from the local community centers and senior welfare centers in Seoul, and the total collected cases were 331. After data cleaning, total 309 cases were used. The structured equation modeling applied to analyse the direct and indirect effects. The findings were followed : First, the community environment did not directly affect level of depression. Second, in the indirect effect analysis, social capital was not statistically significant, thus indirect effect was confirmed only through the SOC. To be specific, the higher the satisfaction of the physical environment increased SOC, and decreased the level of depression. The results of this study shed lights on practical interventions to promote mental health of the middle-aged and older adults those who are exposed to poor community environment.

Since the 1990s, discussions regarding green libraries started in the U.S.A, in the name of 'library and the environment', 'Green librarians', 'constructing of environmental sources', 'noise and library', 'building libraries as an environmental alternative' and etc. Currently, green libraries certified by an evaluation system are more than 50. This study proposes a direction to build a green library. The study analyzes national and international green libraries certified by the evaluation system. The cases are analyzed based on the six evaluation factors in the LEED certification system; Sustainable Site, Water Efficiency, Energy and Atmosphere, Material and Resources, Indoor Environmental Quality, Innovation and Design Process. Since the evaluation system focuses mainly on the architectural aspects, there was a need of expanding the concept of eco-friendly in this research. The newly expanded eco-friendly concept includes services, content, and supplies of libraries.

Development of digital technology has become closely connected with housing environment. Especially for the matured population, it is very important because they need substantial support in their daily lives. Therefore, the purpose of this paper is to identify needs of digital network services for future housing development. Previous researches were limited to digital technology of network systems and its usages. On the other hand, this study focuses on not only the technology but services. This study consists of literatures review and empirical survey. The subjects were the mid-age and pre-elderly between 45 to 65. The analysis of this study results outlined as follows: First, the pre-elderly appeared to have, in general, positive perceptions about digital services of the housing environment. The results of needs for each space's, showed strongly in basic safety and aiding system for memories. Second, there are differences in needs according to respondent's characteristics such as sex, income, job, house type, experience in digital system. Third, there are differences between what they think and what they really responded in both spaces and services. It menas that present planning elements may not attractive and suitable to residents. Therefore it is necessary to redesign the services. In the future, the most important thing is, making comfortable space not convenient space. That is, excluding unnecessary elements and pick up the right ones for resident's real demands.

The purpose of this study is to enhance the development of construction waste-recycling technologies and its economical efficiency by developing environment-friendly tetrapod, precast concrete, where recycled aggregate is used in order to promote recycling of waste concrete. The results of concrete mechanic characteristics experiments by the circulation coarse aggregate-replacement ratio are as the following. The circulation aggregate is lower and higher than natural aggregate in specific gravity and absorption ratio, respectively so that in case of mix proportioning, unit volume increases, while unit aggregate amount decreases. From the result, sufficient experiments of physical characteristics of circulation aggregate are required to get proper mix proportioning. When circulation aggregate-replacement ratio increases, compressive strength tends to decrease comprehensively, but 50% of replacement ratio is good enough to use. When circulation coarse aggregate's replacement ratio is 0%, drying shrinkage, which causes cracks in concrete and deteriorates durability, shows the minimum length change and the higher the ratio, the larger the length change. Thus. when using circulation coarse aggregate, drying shrinkage should be fairly examined. In freezing-and-thawing resistance, weight loss tends to comprehensively increase its loss at the circulation aggregate-mixed site. And the examination of surface aggregate-omission ratio is further needed and dynamic elastic modulus and durability factor(DF) require more study as well. In order to use circulation aggregate to tetrapod, a clear standard for strength should be first prepared and at the same time, more study about durability is needed.

According to the revision of the Convenience Act for Persons with Disabilities, parks and park facilities where the first park development plan is established after December 4, 2021 are mandatory, and parks must be equipped with convenience facilities for the disabled. Hence, this study aims to derive the improvements of the park evaluation index by analyzing the park certification evaluation index, the building certification evaluation index of park facilities, and the evaluation reports of the current certification status cases. As a research method, first, the certification of parks and park facilities were compared and reviewed with the Park Green Act, and differences in the certification process and certification performance were compared and analyzed. Second, differences and common items were derived by analyzing barrier free (BF)-certification evaluation indicators for parks and buildings. Third, improvement plans were derived after analyzing differences and problems in 4 BF-certified parks and four building certification cases of park facilities in certified parks, focusing on the self-evaluation report and examination results. As a result of analyzing the park and building evaluation indicators, the items for which the evaluation purpose, evaluation method, and evaluation items were commonly applied to 7 access roads for each facility, 5 parking areas for the disabled, 2 guide facilities for information facilities, 14 in 5 categories of sanitation facilities, and 1 for other facilities. In the case of sanitation facilities, there is no case where it was evaluated as a park. If the park does not have an attached toilet, the park is certified as a building. Hence, it would be essential to establish the concept of an attached toilet and discuss the application of the evaluation index on the park sanitation facility. The score of buildings in parks and park facilities was lower than that of the self-evaluation results, and the certification grades of buildings declined in three cases. The items with the highest standard deviation were BF walking continuity for parks and the path to the main entrance among access roads for buildings. As a result of analyzing the park and building evaluation results of 19 common evaluation items except for sanitary facilities, the difference in the grades of the evaluation items for each case site except for one item appeared. Therefore, applying common detailed calculation criteria for items evaluated in common with parks and buildings is needed. Since sanitation facilities have no cases of park certification and are not certified as buildings, it is essential to establish the concept of attached toilets and discuss the application of park sanitation evaluation indicators. It is necessary to develop an evaluation index suitable for the characteristics of the park, such as adjusting the items that are not evaluated in parks and establishing an evaluation index considering the ones of parks. It expects that this study would be used as primary data for improving park certification indicators.

This study analyzed the healing effect of the design elements of healing environment from the perspective of environmental stress, which is one of the contents of environmental psychology. By examining the objective healing effects of the design elements of the healing environment, this study attempted to prepare a theoretical basis for contributing to the construction of a systematic and systematic healing environment. This study consists of three phases. Firstly, three environmental stress theories (Attention Recovery Theory, Evolutionary Psychology, and Environmental Stress Model) were examined to review the academic basis of which the theoretical concept of the healing environment has been derived and developed. Second, we analyzed 16 previous research on the design elements of healing environment and used them as an analysis framework of this study. Thirdly, 11 foreign studies that proved the healing effects of healing environment design elements through objective research methods were considered and analyzed as an analysis framework, and the basis for applying design elements in constructing healing environment was prepared. The research results are as follows. First, the concept of healing environment was developed from Lazarus's psychological stress theory and Ulrich's theory of evolutionary psychology, suggesting that it can be used as one of the noninvasive healing tools that affect stress reduction. Second, the healing environment design elements could be divided into 15 factors and categorized as physical environment, psychological environment, and social environment, and it was found that most of them were mentioned and studied in the previous research in order of nature-friendly, aesthetic, and openness. Third, most of the previous research on the healing effects of the design elements of the healing environment were related to natural affinity and aesthetics, and it was found that the visual elements of the healing environment could affect the actual stress reduction.
