The purpose of this study was to explore typical behaviors of spatial usages such as patterns of spatial usages, perception on residential spaces, and furniture arrangement. A questionnaire survey and interview were adopted in this study, and 146 residents living in apartment with 3 bedrooms, stairway access, and 3-bay style in the City of Gwangju. The major findings of this study were that 1) dining-kitchen (DK) was conceived and used as a space not only for dining but also family gathering and guest reception. Dining table without refrigerator was frequently found in furniture arrangement of DK, and refrigerator has been relocated in utility room facing DK. The results imply the need for social interaction that has been growing. Anbang (master bedroom) has been perceived and used as couples' private area, aside from the traditional function of family interaction. A coordination of both bed and wardrobe out of different furniture arrangements was popular in anbang. Living room was used as a multi-purpose room carrying out various activities such as family gathering, guest reception, and housekeeping. Sofa and cabinet were the most common furniture arrangement in living room. The research results are a basis for residential open housing system.

Increasing affectability of high-speed Internet and convenient access devices has made the Internet a major source of information search and sharing. As the provision of information has rapidly becomes an important and viable business model, the objective utility and marketability of information contents have become a focus of interest among many academicians and managers. Researchers have traditionally focused on the design of the interface, availability of resources, network accessibility, the format of web sites and their underlying systems. However, the usefulness of contents has been left as a little explored issue. To correctly diagnose and pursue the viability of contents provision business a shift of perspective is required : a shift from technology-oriented perspective toward user-oriented perspective, and a shift from form and design focus toward content focus. This research attempted to analyze consumer-oriented information quality in a more systematic way by focusing on a limited domain travel-related information contents. We proposed a relationship among consumers'behavior, characteristics of information, and the values of information measured by users. An empirical examination of the model was performed using a survey on Internet users in Korea. Implications are drawn for managers responsible for creating marketable contents.

The objective of this study were to classify the contents of clothing purchase motives and to examine the differences in post-purchase dissatisfaction and satisfaction of clothing according to the clothing purchase motives. Questionnaire was comprised of 36 Likert type items of clothing purchase motive measure, 15 items of post-purchase clothing dissatisfaction measure, and 1 item of satisfaction measures. Samples were 492 women in Incheon, Korean ; 279 were college students and 213 were housewives. The data were analyzed using factor analysis, cluster analysis, one-way ANOVA, Duncan's multiple range test, and χ2-test. The results of the study were the followings : 1. Subjects perceived 'becomingness' to be the most important motive, 'attractiveness of color' the second important, and 'salesperson's recommendation' the least. 2. 6 factors of clothing purchase motives were derived by factor analysis : F.1 'clothing utility and deficiency' ; F.2 'clothing quality' ; F.3 'financial frugality'. 3. Subjects were classified into the three motive groups by cluster analysis of the 6 factors : G.1 'the clothing appearance and others' influence' ; G.2 'the clothing quality and deficiency' ; G.3 'the motiveless'. 4. More college women were distributed in clothing appearance and others' influence group than housewives, while more housewives were distributed in clothing quality and deficiency group. 5. The clothing appearance and others' influence group expressed the highest post-purchase dissatisfaction and the lowest post-purchase satisfaction. The clothing quality and deficiency group expressed the highest post-purchase satisfaction, and the motiveless group expressed the lowest post-purchase dissatisfaction.

Gloss is very important optical property influencing the perceived quality of the paper surface as well as the surface after printing. Although the average gloss level of paper products or printed images is important to meet end use specifications, the occurrence of gloss mottle, or non-uniformity of gloss, is often of greater concern for meeting quality requirements, especially for the high gloss paper. Gloss variation originates from the irregularities of paper surface, especially surface roughness of paper. Roughness of paper can be divided into micro-roughness (under $1\mu m$ scale in variation) and macro-roughness (over $1\mu m$ scale in variation) depending on the scale of the irregularities. A clearer understanding of the gloss variation of paper can be achieved by separating the contributions of these two scales of roughness, and characterizing them independently. In order to do this, a novel gloss measuring method was introduced. This can detect local gloss with very high resolution. The effect of macro-roughness on gloss variation, which was identified by the measurable surface topography, was separated from the total gloss variation by using this method. The effect of micro-roughness was then estimated indirectly. The local gloss variations of various paper samples were then evaluated to demonstrate the utility of this approach.

The purpose of this study was to reveal the relationship between self confidence in fashion coordination and fashion information search of men. This study also examine the utility of services of fashion coordination in fashion store. A questionnaire was developed and data was collected from 248 male consumer in the age of $20{\sim}29$ living in Busan and it was analyzed by the statistical method of frequencies, factor analysis, analysis of variance and regression. The results of this study were as follows: First, information contents of fashion coordination include four dimension, such as fashion style information, knowledge about fashion item, way of putting-on for stylish appearance and beauty information. And degree of search fashion information was significant different among groups classified by consumer's level of self confidence in fashion coordination. Second, multiple regression analysis revealed that consumer's self confidence in fashion coordination could be predicted from the amount of search fashion information contents and information sources. In conclusion, fashion information search was important factor which influenced on self confidence in fashion coordination. and male consumers perceived fashion coordination services in fashion store will be useful information.

The objective of this paper is to gain a better understanding of factors influencing digital piracy and the use of paid services on the web. A model identifying and describing various factors which affect decision$\sim$makers' attitude toward sharing digital products and online behavioral intentions is constructed based on established theories of human behavior. The relationship between the continuous intention of sharing the products and the intention to use online services is also discussed. Findings show that a independent relationship exists between illegal and legal behaviors, which means stopping piracy by individuals can not lead to their buying of the products. Also while the attitude toward piracy was significantly related to the continuous intention of piracy behaviors, did not necessarily lead to the use intention of online services. The data also show that beliefs concerning consequences of digital piracy were significant enough to alter one's behavioral attitude. There was a significant relationship between perceived consequences and the intention to pirate digital products or to use paid services. The results also show that while the effect of economical and ethical factors were ascertained, that of social and legal factors have not been found. Self$\sim$efficacy has a moderating effect on the relationship between the attitude toward piracy and both intentions of online behavior. The implications of the findings to research and practice are discussed.

The purpose of this study was to determine how the different number of channels of coils were related in the perceived signal intensity under identical parameters and area. Dedicated knee phantoms were scanned consecutively using both of the 16-channel and 8-channel knee coils. The T1 weighted and T2 weighted sequences were acquired using both coils to compare the signal intensities according to the number of channels. As a result, the 16-channel knee coils outperformed the 8-channel knee coils and the signal intensity was significantly increased in both of the T1 and T2 weighted images with the 16-channel coil. In conclusion, it is considered that better signal intensities and more clinical utility can be provided, when coils with more number of channels are used rather than using the coils with smaller number of channels.

In the field of architecture, concrete and steel bars are the most common and popular combinations. The relationship between the two in a structure is a complementary good that increases in utility when consuming both materials at the same time. However, the combination of the two, which has been perceived as semi-permanent, often faces repairs or reconstruction without its lifespan reaching decades. There are a number of deterioration factors at work for the reason for this phenomenon. Among them, the neutralization of concrete in particular refers to the process in which calcium hydroxide inside concrete reacts with carbon dioxide and loses alkalinity, which creates a corrosive environment for rebars inside concrete, causing serious damage to concrete. In this study, we intend to use a multi-physical analysis program using finite element analysis method to analyze the degree of carbonation according to the internal temperature and concentration of carbon dioxide in concrete, thereby contributing to the prediction of long-term neutralization of concrete and the research related to measures for neutralization of concrete.
