  • The purpose of this treatise is to study external form and internal meaning of minimal expression fashion which appeared as a major stream in modern fashion trends to understand one aspect of modernism in fashion and also to gain insight into internal value of human beings through fashion. The results can be summarized as follows : Firstly , minimalism is a trend in art attempting to seek essence of the object by presenting simple and disciplined expressions by minimal formative means and minimal production process. Secondly, minimal expression in fashion means seeking simplicity an dpurity by using minimum design elements and minimal productive process. Thirdly, external from of minimal expression fashion can be created through application of following minimal expression techniques. 1. Minimal expression techniques in terms of line mean smooth curve flowing along body contours, straight lines of diagonal lines into desciplined silhouette or rendering internal contour lines. 2. Minimum expression techniques in terms of forms mean forms of smooth curves flowing along boyd or forms with simple geometric forms from qualitative aspects, In terms of volume it means quest for essence of pure body itself by revealing body as it is by minimizing the size of dress or its area and herein is contained using simple geometric pattern or utilizing textiles without any patterns.3. Minimal expression techniques by colors mean simple colors such as primary colors, colors without clear distinctions or natural colors and in terms of quantity it means quest for one color within one item of dress or combination of each items when getting dressed. 4. Minimal expression techniques in terms of fabrics mean fabrics with simple surfaced. In terms of quantity it means quest for essence of tight fitting thin textiles to human body or using transparent materials to human body thus exposing body contours as it is. 5. Minimal expression techniques in terms of productive process mean minimizing process of tailoring , sewing or ornamenting and seeking for simplicity and purity. 6. Minimal expression techniques in terms of manufacturing process mean selection of technique conveying simple image with disciplined simple image.

  • Taking samples of data and using samples to make inferences about unknown populations are at the core of statistical investigations. So, an understanding of the nature of sample as statistical thinking is involved in the area of statistical literacy, since the process of a statistical investigation can turn out to be totally useless if we don't appreciate the part sampling plays. However, the conception of sampling is a scheme of interrelated ideas entailing many statistical notions such as repeatability, representativeness, randomness, variability, and distribution. This complexity makes many people, teachers as well as students, reason about statistical inference relying on their incorrect intuitions without understanding sample comprehensively. Some research investigated how the concept of a sample is understood by not only students but also teachers or preservice teachers, but we want to identify preservice secondary mathematics teachers' understanding of sample as the statistical literacy by a qualitative analysis. We designed four items which asked preservice teachers to write their understanding for sampling tasks including representativeness and variability. Then, we categorized the similar responses and compared these categories with Watson's statistical literacy hierarchy. As a result, many preservice teachers turned out to be lie in the low level of statistical literacy as they ignore contexts and critical thinking, expecially about sampling variability rather than sample representativeness. Moreover, the experience of taking statistics courses in university did not seem to make a contribution to development of their statistical literacy. These findings should be considered when design preservice teacher education program to promote statistics education.

  • To ameliorate a long-standing, persistent housing shortage in Korea, large-scale massive housing production has been an imperative, and the extensive growth highly values development and consumption. The state's priority for the quantitative growth of housing stock has proved to be successful, but the state faces with economic and environmental crises in a global era. To achieve the qualitative growth, the previous administration pronounced a green growth policy from the inception, and a series of strategic measures under a holistic plan have been taken widely and vigorously. As part of the strategies, the green home project was undertaken, and simultaneously the movement of green living led by the governance has been activated. However, little attention to the grassroots effort was paid and the efficacy hasn't been adequately addressed. This study examines the factors affecting green living of residents in multifamily housing. Based on public guidelines to green living, 106 specific items were drawn out and largely categorized into 6 areas (water, waste, transportation, air quality, consumption, and energy), and the questionnaire was constructed using them. Of 750 survey forms mailed out, 161 responses were returned and the collected data were used for statistical analysis. The findings indicated that varying degrees of green living was well practiced, the state-led green home project was relatively well recognized, and the green growth policy was strongly supported. Also the respondents' attitude toward green living were more associated with demographic variables than housing characteristics, and familiarity with green home project was related to attitudes toward green living. Since the on-going approach to green living has focused on simple and economical ways, it has proved to be effective but progressive strategies to make living greener are necessarily developed.

  • The development of mass media in the $20^{th}$ century has resulted in the rapid growth of the fashion industry. Fashion magazines like are performing the function of spreading new styles in addition to simple provision of fashion trend information. Therefore, the present study tracked the trend of changes in the cover models of USA during the last 10 years $(1997{\sim}2006)$, and examined qualitative and quantitative changes in the contents of USA for the last 20 years. According to the results, $50{\sim}75%$ of cover models were super models during the period from 1997 to 2006, but the percentages of fashion models and celebrities became similar to each other in 2001, and from 2002 to 2006 celebrities occupied around $75{\sim}92%$ of cover models. When the contents of USA were analyzed by category, columns that showed strength in 1986 but decreased gradually until 2006 were style suggestions(p<.001), fashion shooting on the theme of TPO and items(p<.05). Fashion columns that showed weakness in 1986 but increased through the 1990s and until 2006 were celebrity style(p<.05), item introductions(p<.001), shopping information(p<.001), designer interviews(p<.05) and fashion shooting on the theme of mood and celebrity(p<.05). These results suggested that the function of USA as a fashion magazine was mainly the provision of information on how to wear the new styles in 1986, but nowadays the contents have changed to information on what to buy. In addition, the results show that contents using highly popular celebrity increased rapidly in the 2000s.

  • The object of this research is to take a bilateral look into cultural exchanges of the Netherlands and Japan through the East India Company and thereby improve the general understanding in regards to the exchanges of costume cultures between the East and the West. The study conducted qualitative analyses on features of contemporary costumes of the Netherlands and Japan from 1602 to 1799 by investigating the secondary sources, such as the histories of costumes, arts, and literature. The results are as follows; the traditional sleeves of the Japanese Kimono were basically cut out in a straight line. However due to the growing popularity of the kimono home gown in Europe, the producers of the kimono in India as well as several other European countries modified them into western-style sleeves. Regarding the costumes of the Netherlands, which were introduced to Japan, the study found that Japan imported Dutch fabrics, instead of specific clothing items. In Japan, costume controls and anti-conspicuous consumption regulations among social classes including a closed-door policy had negative effects on both developments and exchanges of costumes of the country. However, when it comes to the Jinbaori, a costume for ruling classes, Japan was open to using fabrics, patterns and designs of the West. In light of what have been discussed so far, the study confirmed that the costume exchanges between the two countries started long after their first business of the general cultural exchanges. Though it is clear that the advancements in the natural sciences that the Japanese made can be attributed to the West, Japan was one of the nations that impacted the costume cultures in Europe.

  • The purpose of this study is to analyze consumers' purchase behavior for the counterfeits of fashion luxury brands. The research method of the study used a naturalistic approach. The first participant observation was carried out in the internet sites in order to collect the data on the purchase behavior for counterfeits; and the second participant observation was applied in the Dongdaemun shopping mall, Namdaemun shopping mall and Itaewon shopping mall; finally 6 informants were selected and then an interview was held with them. The results of the study are as follows; 1. The reasons for the first purchase of counterfeits are variously shown according to life stages, and the repetitive purchase behavior is influenced by the degree of satisfaction for the first purchase. The information collection for counterfeits is widely made through various media, and especially the information collection is active and positive in the case of planned purchase but it is passive and negative in the case of unplanned purchase. 2. The most important criteria in purchasing counterfeits is the degree of similarity with luxury brands and other criteria include price, design, utility etc. The majority of purchase items is not clothing but miscellaneous goods which are more similar in terms of design and quality. The purchase of counterfeits is made by impulse purchase but the purchase of luxury brands is made by planned purchase. 3. The rationalization mechanism for the purchase of counterfeits is observed in all informants, which is a sort of defence mechanism for avoiding a guilty conscience to buy illegal goods.

  • Purpose : The study is to develop the medical information system for the hospice which can be implemented actually by considering the imitations with respect to hospice programs and hardware resources. And the ultimate goal of this study is the promotion of the hospice. Methods : The study is of qualitative research and is performed by the literature survey in related fields. And the precedent studies are taken into account also. Through these surveys, crucial items are revealed and the solutions for thorn are proposed. Results : The analysis of the hospice program shows that the MIS can be applied to the hospice with a greater efficiency. This gives the rationale that the MIS for the hospice should be set-up as soon as possible. Conclusion : In establishing the system, recommended is that the hospice model take the gradual development rather than the integrated one from the on-set stage. Further the system design should take several limitations into account to be a realistic one.

  • GPI (Group Pollution Index) using 29 indicator groups of Korean benthic macroinvertebrates was proposed in 1992, a higher category taxa-level index developed for rapid field assessment of organic water pollution. This study was performed to revise the assessment scheme of GPI based on taxonomic performance and ecological information accumulated since 1992. The original GPI was renamed SBMI (Simple Benthic Macroinvertebrates Index), and SBMI was based on saprobic valency of 26 indicator groups composed of higher category taxa (mainly family ~ phylum) excluding some genus or species-level taxa. SBMI revealed highly significant correlation with concentration of 5-day biochemical oxygen demand ($BOD_5$) (correlation coefficient r = 0.78, n = 569 sites), total suspended solids (r = 0.69), and total phosphorus (r = 0.77). Also, SBMI revealed strong correlation with Shannon-Weaver's species diversity (r = -0.85), Margalef's species richness (r = -0.85), and McNaughton's dominance (r = 0.83). Determination coefficient of SBMI to concentration of water quality items and values of community indices such as species diversity was 3 ~ 8 % and approximately 11 ~ 14 % higher than that of GPI, respectively. Correlation between SBMI and water quality factors or community indices such as species diversity did not reveal much difference compared to that of species-level indices, such as BMI (Benthic Macroinvertebrates Index) and ESB (Ecological Score of Benthic Macroinvertebrates). SMBI is a simple-qualitative index with higher category taxa easily identified, and is applicable for rapid field assessment of water environment impairment.
