Today, according to population decrease and aging of the old due to the decline of birthrate in our society in $21^{st}$ century, there is a stiff increase of the aged group. Complying with the request of epic needs, as there was a full scale amendment of law of the aged welfare in 1997, the centers appeared differently based on the regional dimension, the difference of the number of persons to be accommodated, and the social and economic characteristics. Coping with these problems occurring, along with the necessity of welfare facilities for the leisure of the aged, the government prepared and carried out a number of plans for the service of the aged and securing of facilities. This practice of the government, however, centered on the crease of service in quantity other than the quality, resulting in a situation of lacking the welfare facilities for the aged meeting the requirement of the aged in their aspect of consumer. On the contrary, building the welfare centers in Japan started in 1960 with a rapid increase of the number of centers in 1970s, and there were 2,214 welfare centers in operation in Japan in 1995, keeping a high level of service in quality and quantity. Thus, this study aims to present basic materials necessary for the criteria of space designing plans for the aged welfare centers in Korea through case analysis of the facility criterion, area constitution and space constitution by the floor that play an important role in regional welfare facilities for the aged in Japan.

Environment-friendly materials are increasingly used as building construction materials nowadays, and the market share of those is growing. Accordingly, the research and developments in terms of environmental value are progressing steadily now. The main characteristics of environmental products are far-infrared radiation, negative-ion emission, electromagnetic wave shielding, and antimicrobial property. These products are often used in mortar and as spray on the finishing material. Nevertheless, there are hardly any research on the functional properties of concrete, the main material in construction field. Thus, we evaluated such basic properties of concrete as slump, compressive strength and air content while using such functional materials as sericite, wood-pattern sandstone, carbon black and nano-metric silver solution to focus on their functional properties like far-infrared radiation, negative ion emission, electro magnetic wave shielding, and antimicrobial activity in this research. The results indicated that the most useful material in the functional materials was carbon black. Sericite and nano-metric silver solution had a little effect on the functional property. Moreover, although wood-pattern sandstone had very high functional property, it exhibited too low compressive strength to be applied, to concrete as a factory product. Antimicrobial property of nano-metric silver solution in the concrete was not clear demonstrated, but if these specimens were to be aged in $CO_2$ gas for a long time, it might be apparent.

The application of the high-performance insulation materials for buildings seems to be an essential measure for reducing energy use in buildings. Phenolic foam is a readily available insulation material with thermal conductivity of about 0.018 to 0.020 W/(mK). It has the advantage of higher thermal resistance and better fire resistance compared to other conventional building insulation materials. Insulation material used for building envelope is regarded as one of the decisive factors for building's energy load. Furthermore, the degradation of its thermal performance over time increasingly affects the building's energy use demand. Generally, the life span of conventionally built buildings is expected to be more than 50 years, so the long-term performance of insulation materials is critical. This paper aims to evaluate the long-term performance of phenolic form boards through an accelerated aging test. The tests were conducted according to BS EN 13166 and KS M ISO 11561. Based on the results of the accelerated aging test, the thermal performance variation of the material was analyzed, and then its aged value after 25 years was computed. Also, the characteristics of the phenolic foam board's long-term performance were also examined based on the standard testing methods adopted.

The age-friendly environments have the benefits that they provide not only the elderly, but also the disabled, children, pregnant, and young persons with the convenient environments. The study examined how degree the aged perceived their physical living environments were age-friendly. The data were collected from 525 old peoples living in Busan using by the person to person interview. All 34 items related to the age-friendliness of outdoor space and building, traffic, and housing were analyzed. The aged perceived that the agefriendliness of their living environments were mid-range. This implies that the improvements of their physical living environments were needed. The age-friendliness of housing area was the lowest among three areas. This means that the alternatives for improving the old persons' houses were needed. The characteristics which affected the aged' perception of the age-friendliness of physical living environments were economic level, housing type, home-ownership, and health condition.

With the sex role changes in the post-modern society, men are becoming increasingly interested in appearance and their bodies. Male muscles in particular, which also is a visual manifestation of masculine strengths, has become the focal interest for those men who care about appearance management. The purpose of this study was to identify the extent to which Korean culture emphasizes muscles in defining masculine body, and to understand Korean men's perception of muscle building and their bodies. For this purpose, a content analysis and a survey were conducted. The content analysis aimed at identifying the ideal masculine image represented in the ads featured in male fashion magazines. For the purpose of comparison, U.S. magazines were also examined. The result showed that male models' images shown in Korean magazines were not significantly different from the male images in American magazines in terms of the body size, muscularity, and the nudity of the models. A survey to 339 men aged between 20 to 50 living in Seoul area was conducted to explore the motives of muscle building, the criteria men use to evaluate muscled bodies, and the influence of muscle building on body satisfaction. Factor analysis and analyses of variances followed by Scheffe multiple comparisons were conducted for data analysis. The results showed that physical appearance improvement is one of the motives of muscle building especially for younger men. Muscle building in general is found to contribute positively to men's body satisfaction.

Small bridges carry out only general inspections based on visual inspection. The Bridges with more than 30 years of public use need to be decided on whether or not they will be reconstruction according to aging. However, there are some situations that need to be determined only by appearance condition, which is insufficient in terms of safety maintenance. In this paper, the condition evaluation and the load carrying capacity evaluation were carried out for aged small bridges. A comparison of the evaluation results was conducted to examine the appropriateness of the maintenance related to the decision making of the reconstruction. As a result of reviewing, two of the bridges showed that there are no abnormality in the safety of the state evaluation, but the load capacity were insufficient. Thus evaluation the safety and performing the reconstruction decision of aged small bridges by visual inspection alone with may cause problems. Therefore, it is necessary to carry out additional research on the ambient measurement and load carrying capacity evaluation for the maintenance of the bridges, and to supplement it through application of the bridge management system.
