The purpose of this study was to develop functional and environment-friendly polyester fabric by irradiating Ultra-Violet, which was produced by the low-pressure mercury lamp. UV irradiation was conducted with various treatment times and distances. Also, pretreatments of solvents and photoinitiator were used to improve the surface modification effects. The effects of UV irradiation on the moisture regain were found to increase gradually with increase of UV treatment time and decrease of treatment distance. Compared the effects of UVC and UVA, UVC was more effective than UVA. Moisture regain and wicking of PET was increased after UV treatment in our experimental condition. And owing to increasing of moisture regain, static charge was decreased. Pretreatment of solvents such as methanol, ethyl ether and addition of photoinitiator such as Benzophenone accelerated surface modification. The moisture regain was increased but wicking was decreased with pretreatment and addition of photoinitiatior. Therefore it is considered as inappropriate f3r clothing because of wicking effects. Yellowness, tensile strength and elasticity slightly decreased after UV irradiation.

In this paper the relationship of various types of work-family interaction (i.e. work-family conflict, and work-family enhancement) with individual, family, and employment characteristics was explored in a sample of 1000 married employed women with preschool children. By using cluster analysis, we tried to reveal whether specific combinations of the various dimensions of work-family interaction (WFI) exist. Our results showed that employed women did not simply experience work-family conflict or work-family enhancement, but that they should be classified in four distinct clusters: (1) 189 employed women experienced primarily work-family enhancement(i.e. positive WFI); (2) 289 employed women experienced primarily work-family conflict(i. e. negative WFI); (3) 338 employed women experienced work-family conflict and work-family enhancement simultaneously(i. e. both positive and negative WIF); (4) 184 employed women did not experience either work-family conflict or work-family enhancement(i. e. low WFI). Results further showed that the emerging WFI-clusters appeared to have distinct profiles with respect to individual, family and employment characteristics.

This study analyzes the state and products of shopping malls that sell naturally dyed products in Japan. In this study, 37 natural dyeing shopping malls were selected. The results of this study are as follows. There are many natural dying internet shopping malls located in the areas of Tokyo, Kyoto, and Okayama. The most frequent dyes were indigo, followed by akane, persimmon, mud, vegetation, and tea. The highest ordered product categories were accessories, followed by adult clothes, and interior decoration products. The most frequent products were adult hats, followed by towels (handkerchiefs), scarves, T-shirts, and bags. For the price of products, 3,000-4,000${\yen}$ was the highest for T-shirts, with 2,000-3,000${\yen}$ and 4,000-S,000${\yen}$ for newborn baby and child clothing, 5,000-10,000${\yen}$ for hats and bags, 3,000-4,000${\yen}$ for scarves, and 1,000-2,000${\yen}$ for towels (handkerchief). Concerning product information, most of the shopping malls offer the product size and the product explanations, but over half of them did not show the properties or directions for handling the product.

Recently a prevailing trend in marketing has been the use of consumer participations or prosumer activities and this has caused consumers to become skeptical in their treatment of information found on blogs. Therefore, these marketing practices can be usefully examined to ensure they represent a neutral source of information for consumers. This study thus investigated married women's production activities of consumer information using personal blogs, their motives and experiences, and the characteristics of the information they produced. A qualitative study was undertaken using focus group interviews with two groups of sixteen married women in their 30's and 40's. Results suggested that personal bloggers' information production activities were primarily initiated by businesses and that bloggers were paid for their activities either with money or through the products they reviewed. Although the information produced was, because of its basis in consumer experience, consumer friendly, its quality was limited in the sense because it primarily reflected the perspective of businesses. The bloggers, themselves, expressed ethical uncertainty about their practices. Implications for consumer education and policy were also discussed.

Recently, there are getting popular form generation-related design methodologies and scientific discourses about the nature of nature in the environmental design. The necessity of visual perception and cognitive research is growing in this respect. Accordingly, this study was designed to discuss environmental design and cognition in the ecological perspective. This study was intended to study the structural factors of cognitive ecological space. This study focused on the systematic principle of new environmental design based on cognitive ecological approaches and what kinds of design effects this design principle has on the human being in the long nm. The results are as follows. First, the results suggests that fractal pattern should be an alternative to design cognitive ecological space and new paradigm of architecture is based on the nature of nature and human sensibility. Accordingly, they have proposed that fractal design is more empirical and environment-friendly than rational linear design. Second, this study classified the variables of cognitive ecological space into nature, tradition, preference judgement, aesthetic value, and schema. Accordingly, such features as symbol, tradition, and nature restricted by modernistic ideology should be added to new paradigm-based environmental design. Third, accordingly, this study stresses that cognitive ecological environmental design doesn't include buildings of modernism and deconstruction and is based on new science of complexity.

The past concept of constructing houses was focused on how to overcome the limitation of consuming natural resources such as energy and materials, which increased the official cost and the environmental pollution. On the other hand, the echo-friendly concept has considered the harmony between human being and nature more critically and has applied the characteristics of natural environment into a unique dwelling design by developing constructs and materials adjusted to the particular climate, making them into a unit of impacting positively the complicated system. The current environmental issue is how a dwelling adapts into a given climate in which the design is applied by ecology without damaging the natural environment. In another word, the main issue in the twenty first century will be how we meet the human needs to dwellings applied by the residential environment. Therefore, we have to provide a hospitable place for residents' mental and physical health through "Green Design", emerging as the critical design of urban collective dwellings. Based on these conceptions, the purpose of this study is to suggest the way of designing the urban collective dwelling applied by ecology, proffering wealthy life style to residents with the preservation of natural environment as applying an ecological concept into the design of collective dwellings that represent a contemporary housing type for urban residents.

Large patch caused by Rhizoctonia solani AG2-2 (IV) is one of the most serious diseases in zoysiagrass. The objectives of this research were to evaluate the in vitro fungicidal effect and in field control of large patch disease of Paraffin oil. In the field experiments, paraffin oil was applied with 1 L/$m^2$ after diluted at 5 ml to 20 ml of oil/1 L of water for the control of large patch on Zoysia japonica in golf course. The same material was tested for inhibition of mycelial growth in vitro. Paraffin oil at 0.5% and 2.0% had a fungicidal effect by 43 to 67% on R. solani AG2-2 (IV) in vitro. In two locations of the field experiments, the paraffin oil provided moderate protection of large patch. It was effective in suppressing large patch development by 48.0% in comparison with a water check after one time application on mid-September in golf course. Paraffin oil may be used as an alternative control agent for environment friendly management of large patch on Zoysiagrass in golf course.
