This study examines shopping orientation regarding bedclothes and the effect of the segmentation of consumers on the image of Hanji yarn bedclothes derived from mulberry fiber in order to contribute to the development of Hanji bedclothes products and consumer marketing segmentation. Data from 294 questionnaires filled out by female consumers in their 30s to 50s were used for statistical analysis. The shopping orientations for bedclothes are classified into six groups (trend oriented, material oriented, price oriented, convenience oriented, individuality oriented, and assurance oriented). Consumers were subdivided into four consumer segments (show-offish, self-confident, reasonable, and unconcerned case) based on shopping orientations for bedclothes. The images of Hanji bedclothes are categorized into four types (classic, practical, aesthetic, and natural) as related to the shopping orientations of consumers. In terms of consumer segmentation, the 'reasonable' segment is more likely to consider the 'classic' image of Hanji bedclothes as the highest image value; however, the 'show-offish' segment provides the highest value to the 'practical' image as compared to other segments.

According to a progress in the quality of life and economy, recent years have seen an increase in interest in the cruise travel. However, it is important to provide them the optimum embarkation environment since there are to be many and unspecified persons staying for a long period on the cruise ship. In the architectural design field, a wide range of efforts are being recently made to meet customer's requirements by considering the rapidly changing society, environment, and economic trend. The most representative one of such efforts is the inclusive design concept. This concept means to perform design satisfying all the function, convenience, aesthetic appreciation, and utility, regardless of sex, age, ability, nationality, cultural background or any kinds of disabilities. Regarding this trend, the convenience-oriented design of a cruise ship using the inclusive design concept was performed in this study. To do this, the composition of cabins and swimming pools, and the exterior of the cruise ship were classified into several groups through literature survey. Then, in the point of view of the inclusive design concept, inconvenience matters of passengers about the cabins, swimming pools, and exterior were also extracted from literature survey. Next, basis designs for them were selected among the classified groups in order to solve such inconvenience matters. Finally, the convenience-oriented design of the Emerald Princess Cruise considering the inclusive design concept was performed by applying the basis designs. As a result, we can see that the inclusive design concept can be applied to cruise ship design.

This study has examined the shift in fashion styles in Korea by analyzing trends in fashion environment and fashion image by seasons in Korea to understand the domestic fashion flow from 2000 to 2006. Since 2000, with the well-being trend, polarization of consumption, preference in luxury orientation, and digital revolution, consumers became individualized and detail oriented. They also became smart consumers equipped with information and knowledge in making choice and purchasing products suiting their taste. To satisfy the consumer trend, fashion market also saw changes such as expansion of advanced distribution, totalization of brands, growing of on-line shopping mall, expansion of outdoor-wear market, and formation of masstage(mass+prestage) market. Fashion images in domestic women's wear since 2000 are analyzed as classic, elegant, minimalism, romantic, bohemian & vintage, ethnic, glam, girlish, kidult, sportive, femiculine, military, and lingerie image. Classic, romantic, and bohemian & vintage are the images that were popular throughout 2000 to 2006. Fashion images of domestic women's wear showed changes in three periods: Sportive image was popular in FW 2002; military image in SS 2003 to SS 2005; and femiculine, glam, and minimalism images in FW 2005 to FW 2006. Through information and detail-oriented emotion, the wide-ranging acceptance of global trends, the consumer tendency towards purchasing products quickly and conveniently, the speedy supply of trendy products both on-line and in-store, and the evolution of the fashion market towards providing one-stop shopping and a cultural space, different fashion images have all emerged at the same time in Korea. It looks like this phenomenon is set to continue for a while.

Educational changes of library and information science (L & IS) at Keio university in Japan, standard of L & IS established by Japanese university educational committee, and trend of library science education in three Korean university were comparatively studied. For the efficient conduct of investigation, the art of states of L & IS was also considered. By the influence of American education, public library-oriented Japanese curriculum had changed to special library-oriented curriculum. Late 60's information science was introduced to their curriculum, library science which based upon information science theory endeavor to make its own field in a n.0, pplied science as harmonized library and information science now. Korean library science education begun with university library-oriented curriculum, accepted special library and information science at almost same time in late 60's. It gave rise to many problems to organized systematic library science. Consequently, it have needed to harmonize these two fields in near future, reorganize curriculum based on this harmonized knowledge and acquire the consensus about fundamental essence of library science education further.

In this study, we tried to suggest a meaningful teaching method that is a mathematical thinking-oriented. After referring to the recent trend of mathematics education, we examined the direction that school mathematics should go. Next, we considered previous studies that deals with teaching methods focusing on the mathematical thinking. On the basis of the above examination, we accomplished case studies that aims at mathematical thinking-oriented teaching. And we explained that these case studies reflects the key points didactics of mathematics such as the education of ‘open mathematics’, constructivism etc. Finally, we proposed the necessity of mathematical thinking-oriented teaching in the current state of school mathematics.

Detecting environmental hazards and monitoring remote terrain are among many sensor network applications. In case of fire detection, it is significantly valuable to monitor fire-spot's shape and trend in time. Mobile ad hoc sensor nodes right round are responsible for sensoring, processing and networking packets, or even launching extinguisher. In this paper, we proposed a ring-oriented Multicast architecture based on "Fisheye State Routing" (MFSR) to organize a group of mobile ad hoc sensor nodes in a multicast way. It is familiar with traditional mesh-based multicast protocol [1] in mobile ad hoc network, trying to concentrates on efficiency and robustness simultaneously. Certain applications-based solution for hazards is proposed, quantitative results including architecture and recovery algorithms of MFSR are also investigated in this paper.

The study is interested in the consumer's mixed choice of the internet and the offline stores. Therefore the purpose of study is to investigate if the clothing shopping orientation of consumers varies when they shop internet and offline, instead of classifying consumers into internet shoppers and offline shoppers. For the purpose, quantitative survey was carried out using 201 questionnaires from men and women in their twenties. The data were analyzed using factor analysis, Pearson's correlation analysis, Spearman's rank order correlation coefficient, t-test, and frequency analysis. The results are as following. First, the clothing shopping orientation structures of offline and internet stores were different each other. As the result of factor analysis, positive, brand oriented, economic, convenient conformity, convenient impulsive factors were extracted from offline store and rational, enjoying, goal oriented, conformity, brand oriented, convenient impulsive purchase factors were extracted from internet store respectively. Second, as the results of investigating the relationship between the clothing shopping orientation structures of offline and internet stores, positive(off)-enjoying(on), brand oriented(off)-brand oriented(on), convenient conformity(off)-conformity(on) had strong correlation s and the rest were peculiar to the each store type. Specifically, the goal oriented factor peculiar to the internet store was noticeable. Third, as the results of investigating the differences between clothing shopping orientation of offline and internet stores, the ranks of strong orientation dimension were different between two channels. As well, the mean differences were significant in goal oriented, conformity, brand oriented, and convenient impulsive purchase dimensions. This study has the significance that it investigated the variance of clothing shopping orientation according to the mixed selection trend of internet/offline.
