The biodiversity of endophytic fungi on Thuja koraiensis in Mt. Hwaak, Seorak, and Hambaek, Korea was investigated. For the 202 isolates collected from the host trees, internal transcribed spacer rDNA region sequences-based analysis identified 32 taxa; 61.5% of the isolates belonged to Dothideomycetes, 27.0% belonged to Sordariomycetes, and 11.5% belonged to Leotiomycetes. This composition rate is somewhat different from that reported in previous studies for endophytic fungi inhabiting trees of the family Pinaceae. In particular, Phyllosticta spinarum in Dothideomycetes is a dominant species among the diverse endophytes of T. koraiensis. Therefore, further critical research is required for this species.

In contrast to apartments, detached houses offer the possibility of more than one entrance connecting interior and exterior spaces. This study examines the location, function, and use of second doors in detached houses in rural areas. The study employs survey and interviews conducted in 2015, focusing on 18 detached houses among 40 houses previously surveyed in 1995. In 1995, 21 second doors were found, while in 2015, 19 were found. The study led to the following conclusions. First, most houses did have second doors installed by 1995 or 2015. Second doors tended to be installed in kitchen and utility rooms. The function of second doors was most closely connected to the kitchen because utility rooms were placed adjacent to kitchens. Secondly, changes in the use and number of second doors were changes in family life cycle and composition, the need for new equipment facilities, the use of new architectural materials, and the installation of new second doors for extension of space. Finally, exterior spaces accessed by second doors tend to be a meeting of semi-interior or semi-exterior space and exterior space only. Those spaces tended to be designed for kitchen fixtures or to support kitchen activities.

The digitalization of our society has brought on the digitalization of housing design and human life. Thus, the concerns for developing digital home have increased. However, most of them has focused on digital technology, not human. This study was intended to examine the residents' housing needs for digital home and to suggest the design guidelines of digital home. The subjects were 400 housewives who lived and used internet in $85m^2$-sized housing unit in the new apartment complex, Busan. The important aspects in digital home design, the residents' needs for digital home design, and the needs for digital system in digital home were examined. The subjects were relatively young in their ages. Also, they had relatively high educational level and middle income. On the base of their housing needs for digital home, the design of digital home like as followings would be desirable: 1) the safe and secure design and digital system, 2) the design to improve residents' health and encourge family interaction, 3) human, warm, and soft interior mood, 4) space composition different from the existing one.

Salivary microbiota alterations can correlate with dental caries development in children, and mechanisms mediating this association need to be studied in further detail. Our study explored salivary microbiota shifts in children and their association with the incidence of dental caries with dentine involvement. Salivary samples were collected from children with caries and their subsequently matched caries-free controls before and after caries development. The microbiota was analyzed by 16S rRNA gene-based high-throughput sequencing. The salivary microbiota was more diverse in caries-free subjects than in those with dental caries with dentine involvement (DC). Although both groups exhibited similar shifts in microbiota composition, an association with caries was found by function prediction. Analysis of potential microbiome functions revealed that Granulicatella, Streptococcus, Bulleidia, and Staphylococcus in the DC group could be associated with the bacterial invasion of epithelial cells, phosphotransferase system, and ${\text\tiny{D}}-alanine$ metabolism, whereas Neisseria, Lautropia, and Leptotrichia in caries-free subjects could be associated with bacterial motility protein genes, linoleic acid metabolism, and flavonoid biosynthesis, suggesting that functional differences in the salivary microbiota may be associated with caries formation. These results expand the current understanding of the functional significance of the salivary microbiome in caries development, and may facilitate the identification of novel biomarkers and treatment targets.

This study empirically analyzed the effects of the Top Management Team (TMT) on organizational performance. We verified whether the age heterogeneity, job heterogeneity (core career, core function and major), and process (communication and integration) of the TMT affect organizational performance (management performance and healthcare service quality evaluation level). We collected data about 473 members of the 2006 TMT in 81 medical institutions. We also utilized statistics of organizational performance from the Ministry for Health, Welfare and Family Affairs and the Korean Institute of Hospital Management. Results of the study showed that the age heterogeneity of TMT exerted a negative effect on the healthcare service quality evaluation level, while the process exerted a positive effect. However, the age heterogeneity, job heterogeneity, and process had no influence on management performance. We discussed the implications of such outcome of the investigation in comparison with the former studies on TMT and organizational performance, and presented its restrictions and future plans.

The purpose of this study is to perform an analysis on the design methods of the "UR Housing Stock Renewal Design Competition" for Hanahata No.27 Housing by the UR Renaissance Agency in Japan. The analysis is done by looking at the aspects of lifestyle, demographics, environment, and community changes. The results are as follows: 1) Since demographic changes are caused by low fertility, aging populations need the support of locally-based social welfare facilities of which the architectural aspect can be examined. 2) Changes in lifestyle, such as diversity of family composition, flexibility of work, and improvement of leisurely activities require residents to have public spaces and facilities 3) Since environmental changes caused by deteriorated housing need the conversion of awareness about housing estates as a social asset. 4) To revitalize the community, houses, public facilities, and communal outdoor spaces must be connected. The results of this study are expected to serve as clues to the future direction of sustainable conversion in Korea.

Objectives: This study examines the relationship between social capital and suicidal impulse for the Metropolitan Seoul residents, paying particular attention on individual and area level risk factors using multilevel analysis techniques. Methods: Data are obtained from the 2005 Seoul Health Indicators Survey and the Seoul Survey. At the individual level, we analyze demographic variables including sex, age, marital status, educational attainments, family income, field of economic activities, having close friends or relatives, and having participating groups or organization. To measure the area level social capital, happiness index, attitude toward minority, the percent of volunteer activity, the percent of having close friends or relatives, and the percent of participating groups or organization are considered. A multilevel logistic regression analysis is conducted utilizing the SAS 9.1. Result: Results show that non-aged, female, not currently married, unemployed individuals tend to have relatively high motivation of suicide. Controlling for individual level covariates, the relationship between social capital and suicidal impulse is neither significant nor substantial. Further, the consideration of area social capital does not explain the variances in suicidal impulse across 25 Kus. Conclusion: Suicidal impulse among Seoul residents is mainly attributable to the composition of individual characteristics but little to the contextual social capital.
