Aging society appears immediate social problem in Korea. Housing for aging is required independent and comfortable housing life to live considering about feature of elderly. It is necessary field to prepare. Aged person who suffers the aging process several stages gets changing weak, so living environment is important aging person aspect of social, psychological and physical point. Finally, aged person living together requires facilities for the naturally communicating and active things. Community of aged person required organization of space for keeping independence and connection with each other. According to space of community, housing for aging should have a different access route. In conclusion, congregate housing of the elderly should be planed organization of space to be solved anxiety and tension and to be aware of joining the community.

Dyeing and discoloration effects on the fabrics of cotton, silk and rayon with unriped persimmon juice were investigated. Color of dyed fabrics treated with persimmon juice only, added 3% tartaric acid or 3% aluminium sulfate was not different each other. Dyeing assistants such as tartaric acid or aluminium sulfate were effective on the prevention from discoloration of dyed fabrics and ultraviolet rays. Discoloration were supposed to derive from tannin in unriped persimmon, ultraviolet rays, oxygen, enzyme and so on, ultraviolet rays at wavelength of 253.7nm was the most active the chromatophores and discoloration. The fabrics could be dyed, when unriped persimmon juice was store at low temperature or freezing.

This study attempts to provide the main reasons and decision-making processes for marriage migration from a Vietnamese' perspective. For this purpose, in-depth interviews were conducted in Vietnam. Interviewees are those who got married to foreigners but are waiting for visas and parents whose daughters are marriage migrants. According to 23 interviewees, the main reasons of marriage migration are as follows: individual aspiration, sacrifice for others, and the circumstantial effects or love. Individual aspiration, in particular, leads to an active pursuit of international marriage. Parental involvement in the decision-making process is rarely found. Decision seems to be wholly made by the female migrant herself based on an individualistic orientation.

The proposes of this study were designed to practical use of credit cards on consumers in Kwang-ju. The 371 subjects formatted questionnaires were analyzed to frequency, percentage, crosstabulation and chi-square test by SPSS WIN 10.0. The main results of this study were as following : First, it is analyzed that most consumers have had more than credit cards. Second, it is tended that consumers have influenced to practical use of credit cards by sex, age, marriage, income and living expenses. Third, consumer is use to the spur of credit card, requirement about businessman, credit card connection system and distinction of sex, age, marriage, income, showed difference of relevant distribution between living expenses all. Based on the above, to make the use of credit cards practical and active, it needs more attention from consumers as well as it needs continuous efforts from the authorities concerned. Accordingly, to prevent consumers from overconsuming possibly by imprudent use of credit cards, it suggests systematic consumer training, from which consumers will learn responsible life as a consumer.

This study was carried out to understand the consumer complaining behavior of rural women leaders and to identify variables affecting complaining behavior. 403 samples were collected from the rural women leaders in rural areas by mailed questionnaire from June 1 to June 20 in 1996. The data was analyzed by frequency, percentage, mean, chi-square, F-test, correlation, regression using SPSS/PC＋ program. Most of rural women leaders experienced consumer dissatisfaction and damage, but they mainly took private complaining behavior. The rate of the non-complaining behavior was 20.1%. They recognized that consumer dissatisfaction and damage was due to external attribution. The results showed that the most influential variables for the consumer complaining behavior of rural women leaders were age and consumer capacity. The older they were and the more consumer capacity they had. the more active complaining behavior was taken.

Natural products have been used as drugs and cosmetics due to their bioactivity and their biochemical diversity. Natural products usually refer to secondary metabolites produced by various living organisms including marine animals, insects, microbes, amphibians, and plants. These secondary metabolites, which usually have molecular weights less than 2,000 amu, are unnecessary for survival, development, growth, and reproduction but play major roles in plant defense systems against other species. These secondary metabolites such as lignans, flavonoids, monoterpenes, and phenylethanoid glycosides showed various biological activities like anti-oxidant behavior, anti-cancer properties, neuroprotective properties, and so forth. Thus, isolation and elucidation of secondary metabolites from living organisms is of great significance to human life.

Recently, interest in energy tranisition is rising. Energy transition requires active participation and cooperation of diverse stakeholders, including users / citizens, in that it requires not only changes in technological factors but also changes and coordination of various social factors. Living labs are attracting attention as one of the ways to do this. This article is a detailed analysis of the activities of the mini-PV living lab in the urban area from 2016 to 2017 at the Seoul, Sung Dae Goal. Through the Living Lab, mini PV DIY products, backup centers, local financial services, and the development of a variety of education and training strategies have been achieved. These activities and achievements were analyzed through questions raised on strategic, tactical, and operational levels, as well as through multi-level perspective and interaction between initiative, regime, and niche. In conclusion, this living lab activity confirmed the possibility of a 'transition lap' to solve social problems such as sustainability of energy production and utilization. In particular, it gained remarkable results in terms of the operational leves of transition management governance, that is, transition experiment, and it was also remarkable in that it was the initiative of citizens. However, it did not proceed without difficulty. In particular, structural problems such as the conflict between the flexibility inherent in living lab and the bureaucratic rigidity of the financial support organization have appeared. There was also a limitation that there was no 'transition field' on the strategic level necessary to replicate and expand strategic niches while spreading the knowledge gained from the transition experiment, forming the vision of transition.

Active window system which can reduce the environmental noises, such as traffic noise and construction noise, from an open window into a room was proposed in the previous works. The key idea of the proposed active window system was that the control sources are approximately collocated with the primary noise source in terms of the acoustic power for global noise reduction throughout the interior room. Moreover, because it is important not to intrude into the living space in the building environment, no error sensors were used and an open-loop control method using control sources at the window frame and the reference sensors outside the room was used for the proposed system. The open-loop control gain was calculated by the interior room model assumed as the semi-infinite space, and the interior sound field was estimated by Rayleigh integral equation under the baffled window model assumption. However, windows with a finite thickness should were considered for the calculation of the open-loop control gain of the active window system since these are representative of most window cases. Therefore, the finite thickness window model based on the Sgard's model was derived and the open-loop control gain using the interior sound field estimated by that model was calculated for active window system. To compare the performance of these two models, a scale-model experiment was performed in an anechoic chamber according to noise source directions. Experimental results showed that the performance for the thickness window model is better than the baffled window model as the angle with respect to the perpendicular direction is larger.

Girls' school uniform evaluative criteria and their uniform modification were investigated. The data were collected by questionnaire from 579 middle and high school girls living in Incheon during the fall of 2003. The uniform evaluative criteria consisted of five dimensions: aesthetics, comfort, economy, management, and status concealment factor. The uniform evaluative criteria were used to cluster the students into five groups: economic, practical, aesthetic, negative, and active. The uniform modifications were investigated in regard to sleeve length, sleeve width, breast width, jacket length, skirt length, hip width, and waist width. The aesthetic and the active groups intended to modify uniforms less in sleeve length and skirt length than the other three groups. There were significant differences in the uniform modifications among demographics: school years, height, weight, spending money, satisfaction/dissatisfaction with spending money, and clothing expenditures.
