Universal design has been disseminated as one of major paradigms in the 21st century throughout the world. Its definition and range of application have appeared somewhat differently from countries and cultures. Japan has been coping with aging phenomena in societies population, and now became aged society. Therefore, universal design has been a big social issue and its design development has tendency of focusing on design for the elderly population. Currently, Japanese housing in its aging society has shown various experiments to provide the elderly with safe and supportive environment to maintain and promote quality of their lives in conventional life settings. Korea already began to undergo this aging process, and now it's in aging society. This means especially designers need to show up their creativity to let design function as a means of social intervention. Therefore this research showed the range of universal design characteristics appeared in current Japanese housing market.

The present study approached conceptually the various problems which occurred in the living conditions during the modernization under the rapid growth drive and their solutions. It seems that the basis of the various problems which occurred in the highly informational and aged society lies in the discord of usability in the living conditions including the tools. It can be said that the secured social equity through the usability plays and important role in enhancing the quality of life of the prosumer, especially the elderly, by providing the self-confidence and the pleasure, and helping the smooth formation of the community The purpose of the present study was to find out the role of the design, as a professional field, on the various social pathological situation and the problems of the living conditions, and, especially, the role of the Universal Design on the desirable reorganization of the living conditions(the change of the living conditions through the community activation) which put the importance on the tool condition.

The purpose of this study was to review the literature and examine the effects on non-pharmacological depression intervention for middle-aged women in Korea. This systematic review analyzed the literature from 2006 to September, 2015. The existing literature was searched in the electronic databases in RISS, KISS and DBPia using the following key words: middle-aged women and depression, menopause and depression, climacterium and depression. Two hundred eighty studies were found through the database. According to PICOTS-SD, twelve studies were included for analysis. Among the twelve studies, four studies were conducted in the nursing field. Six studies were randomized controlled trials. Aerobic exercise, laughter therapy, meditation, aroma massage, counseling and art therapy were performed as non-pharmacological interventions for depression in Korean middle-aged women. The length of each session ranged from 20 to 120 minutes. The intervention period varied from 2 to 24 weeks, and the total number of the interventions ranged from 8 to 72 times. They influenced not only depression, but also physical aspects that are associated with obesity and psychosocial variables, such as anxiety, quality of life, life satisfaction, etc.

Due to the rapid demographic and structural changes, Korea has faced a variety of social issues and quickly entered the aged society since the 2000s. In order deal with this reality, diverse types of welfare policies are emerging in the society as a whole. The government began to supply domestic public silver housing in 2016 to provide against the quickly growing aged society and now, the government is planning to supply approximately 50,000 housing by 2022 for quantitative growth of aged society, by selecting 1st and 2nd designated areas for the project additionally. This public retirement(silver) housing combines 'space' with 'service'. The lower floors are a public silver welfare Facilities and the upper floors are a housing spaces. This type of housing is to deal with requirements of rental housing residents by combining physical space with supporting service. Based on barrier-free design, the complex and unit house have safety handles and alarm bells in the bathroom, undulating washstands, bathroom sliding doors, corridor safety handles, and emergency safety exit lamps in each housing unit so the aged and the disabled can use easily and conveniently. Also, hand rails are installed and stepped pulleys are removed to promote convenience. Currently, the government is planning to increase the supply, focusing on low-income groups, such as beneficiaries of national basic livelihood and the working poor. Recognizing that the public retirement(silver) housing project is at its early stage, this study examined satisfaction, based on evaluations of real residents. This study aimed to obtain more empirical research data and apply them to public retirement(silver) house space analysis. For analysis, this study targeted Wirye public retirement(silver) housing and Magnolia public retirement(silver) housing that are in operation, and literature review, previous research review, and field survey were conducted to examine the present state. Using the questionnaires consisting of four large classification items; Block Layout, Housing Unit, Welfare Facilities, and Barrier-free Design, and sub-details, a survey was conducted to analyze residents' satisfaction. In conclusion, it is anticipated that this study would serve as basic research data about public retirement(silver) housing to increase continuously in future by analyzing public retirement(silver) housing spaces, on the basis of the analyzed data.

In order to elucidate the differences in early successional development among similary aged old-fields having different soil nitrogen (N), caused by the land use history before at abandonment, the response of plant community along an experimental nitrogen gradient (control plot (No), plot NI with 5.8g $N/m^2$, plot N2 with 11.7g $N/m^2$ and plot N3 with 23.3g $N/m^2$) was investigated in a five-year-old abandoned field. Although the N content in soil among treatments was similar at the end of the growing season, N concentrations in plant tissue increased with the amount of N supplied. These results suggest that almost all the N contained in N-enriched soil might be absorbed by plants during the growing season after N supply. Vegetation tended to grow vigorously by nitrogen supply, and the standing biomass increased significantly in plots NI and N2 . Species richness of plants, especially of annuals and perennials, was more reduced than the control plot, and the species diversity was also reduced by N supply. The importance value (IV) of species by N supply differed in each species along the position on the successional sere: Artemisia princeps var. orientalis as the dominant species in this old-field decreased slightly; annuals as the earlier successional species decreased clearly along nitrogen gardients; Erigeron annuals as the earlier successional species and as a strong competitor with Artemisia princeps var. orientalis had the highest IV by small N supply; Miscanthus sinensis and Rubus crataegifolius as the later successional species increased by large N supply. These results suggest that old-fields with high soil N might show the structural and functional characteristics of the earlier successional stages, but community composition in those old-fields might be changed more quickly from the sarlier successional species than the later successional species.

Floor impact sound in high-rise apartment building became one of social problems. A lot of civil complaints on floor impact sound occur continuously and the number of disputes between neighbors in small and aged apartment buildings is increasing. Interests on heavy-weight impact sound pressure level measurement and evaluation method is increased. Previous study reported that heavy-weight impact sound level was changed by the sound field condition of receiving reverberation chamber. In this study, heavy-weight impact sound pressure level change by the receiving sound field condition was measured in standard test facility and mock-up test room. These two experimental conditions were designed to simulate averaged living room of common apartment units. By the change of sound absorption power in receiving room, heavy-weight impact sound pressure level in most of frequency bands were changed in standard test facility and mock-up room. Normalized maximum sound pressure level regulated in ISO 16032 showed wider range of heavy/soft impact sound pressure level. Heavy/soft impact sound pressure level change was became smaller by the application of standardized maximum sound pressure level and ISO/CD 10140-3 Amd 2 method. In the case of standardized maximum sound pressure level, absolute sound pressure level changed. From these results, receiving sound field correction method regulated in ISO/CD 10140-3 Amd 2 is needed for the precision measurement and evaluation of heavy-weight impact sound.

This study focused on the relationship between elderly's participation in lifelong education(participation availability, participating fields) and ego integrity. To verify the correlation of two variables, mediating model structured by life satisfaction was used. The data was Seoul Welfare Panel Data made by Seoul Welfare Foundation in 2010 and the total subject was 1,862 elderly aged over 60. When it comes to research methods, structured equation analysis for verifying the mediating effect was practiced. The findings are as follows: First, life satisfaction did function as partial mediator on relationship between elderly's participation in lifelong education and ego integrity. Second, elderly's life satisfaction increased as participating in field of language, not in field of culture and art. Ego integrity of elderly was increased as participating in field of culture and art, not in field of self-improvement and hobby. This study indicates theoretical and practical interventions to promote elderly's lifelong education based on the conclusion elderly's lifelong education participation in the aging society has positive effects on life satisfaction and ego integrity are meaningful for successful aging.

Initial crop injury, plant growth and yield of machine-transplanted rice of seedlings different in plant age (8-, 20-, and 35-day-old seedlings) after application of herbicides were investigated in field. The herbicides employed were butachlor, dithiopyr, pyrazolate(applied only for 8-day-old seedling), dithiopyr+pyrazolate, dithiopyr+ bensulfuron methyl), and butachlor+bensulfuron methyl(applied only for 20-and 35-day-old seedlings). There was no significant difference in plant growth, yield components and yield between the different-aged seedlings of the untreated check, except for the heading date, The heading date of 8-day-old seedling was delayed for 2 and 6 days as compared with those of 20-and 35-day-old seedlings, respectively. A very slight initial crop injury was found with the tested herbicides for all the different-aged seedlings. No significant differences in plant height and tiller number occurred between different-aged seedlings and the respective untreated check. All the herbicides used gave a good weeding effect. Yield components and yields were not affected by different-aged seedlings after application of the herbicides.

In this paper the response factor is investigated for middle and small size-RC slab aged bridges. The response factor consists of static and dynamic response factors and is a main parameter in the frequency based-bridge load carrying capacity prediction model. Static and dynamic response factors are determined based on the frequency variation and the impact factor variation respectively between current and previous (or design) states of bridges. Here, the impact factor variation is figured out using the impact factor response spectrum which provides the impact factor according to the natural frequency of bridges. In this study, four actual RC slab bridges aged over 30 years after construction are considered and their span length is 12m. The dynamic loading test in field using a dump truck and eigenvalue analysis with FE models are conducted to identify the current and previous (or design) state-natural frequencies of the bridges, respectively. For more realistic considerations in the moving loading situation, the impact factor response spectrum is developed based on tri-axle moving loads representing the dump truck load distribution and various supporting conditions such as simply supported and both ends fixed conditions. From the results, the response factor is widely ranged from 0.21to 0.91, showing that the static response factor contributes significantly on the results while the dynamic response factor has a small effect on the result. Compared to the results obtained from the impact factor response spectrum based on the single axle-simply supported condition, the maximum percentage difference of the response factors is below 3.2% only.
