This study assessed knowledge-based environments for knowledge management in hospital dietetic departments. This study categorized the current knowledge management environment into routine habits, capability, culture and system. A questionnaire was conducted on dieticians in general hospitals with 400 beds in Seoul and Gyeong-in areas. Excluding responses with significant missing data, 160 usable questionnaires were analyzed by SPSS package programs for the study. The result of the study is summarized as follows. The average number of licensed beds in the hospitals was 717.5 and the average number of meals provided daily was 1,626.3. 53.2% of dieticians were aged between 26 and 35. Of the maximum score of 5 points, habits scored $3.65{\pm}.44$ points, capability scored $3.38{\pm}.44$ points, culture scored $3.21{\pm}.46$ points and system scored $2.77{\pm}.74$ points. Hospitals with a high ratio of occupied beds also had significantly higher points in capability, culture and system. The older the group the higher points it scored in habits and culture. The married group scored higher points in habits while the higher educated group scored higher points in habits and capability. The dietitians in charge of clinical nutrition scored higher points in habit, capability and culture while the higher salaried group scored higher points in habit, culture and capability. Therefore this study would provide useful information for the introduction of knowledge management in hospital dietetic departments.

The purposes of this study are to explore the consumption expenditure and consumption-cultural meaning in the process of marriage and to provide consumer education programs for premarital couples. For the purpose, this study uses a qualitative analysis including an in-depth interview and a participant observation. Major findings are as follows: Consumers preparing for their marriage experienced quite a different consumption context, which should be said an exceptional practice from the economic point of view. As the agency businesses for marriage becomes one of the fast growing industries, the marriage of Korea is now under the rule of popular consumption culture. Thus, the exceptional consumption abuse during a marriage process brings about the imbalance in consumers' daily life after wedding ceremony. In this point of view, we can see the importance of consumer education programs for the marriage process. The latter half of this study is devoted to propose the desirable model of the consumer education program for premarital couples.

The present study examined generational differences in ethnicity maintenance among Korean-Chinese to understand the impact of recent social change on a Korean-Chinese ethnic community in China. A total of 1355 Korean-Chinese (557 parents and 798 children), who live in Shenyang, China, participated in this study. The subjects were asked about their language use during daily conversations and cultural activities. They were also asked about their ethnic identity and perceptions of social distance from Chinese people. The results reveal that the Korean-Chinese parent generation is more likely to maintain its ethnic language, while the child generation is more likely to maintain its ethnic culture. Second, more parents than children considered themselves as 'Korean-Chinese' rather than 'Chinese'. Third, members of the child generation show less social distance from Chinese people than do the parent generation. These results show a strong tendency towards ethnicity maintenance among Korean Chinese as well as recent changes in the community. This study argues for the importance of school education and school environment in maintaining the ethnic language and culture of Korean-Chinese children.

The purpose of this research is to investigate and analysis the style of Audrey Hepburn(1929-1993), the most important style icon in the 1950s and '60s from the point of the style of dress in her films - Roman Holiday (1953), Sabrina (1954), Funny Face (1957) and Breakfast at Tiffany's (1966) and fashion activities, furthermore, to know the influence on the contemporary fashion. After 1960s, her style has been recreated by so many designers. In the 1980s, times influenced by post-modernism, there was also the effort to reconstruct the style in the 1950s again. At that time, some Hepburn styles-a reflective of the flamboyant and exaggerating trend in her ages-were appeared by a few designers in the 1980s. Over the 1990s' retro culture, there were a lot of efforts to reemerge the styles in the 1950 and '60s, they led to full-scale reconstruction of Hepburn style - a feeling of the elegance and intelligence harmonizing with the minimal and formal style. By the retro culture adding with the mainstream fashion trend of simpleness and comfort in the year 2000, Hepburn's casual style has been reconstructed to meet the modem need in the 21s1 century. Through these considerations, we could notice that Hepburn style has been recreating from various fashion fields harmonizing with the popular trend of the age.

The purpose of this study was to understand the new generation's culture and to analyze if the characteristics of their lifestyle is significant for the study of new generation's fashion. The new generation's characteristics of lifestyle can be described as a strong pride of their own self and the life which expresses that pride. To analyze this characteristics connecting it with fashion, it is as follows: -It is the egocentric sensitivity culture. In their fashion, there appears a tendency that sense and individuality are counted much rather than fashion. -Diverse fashion information is gained through the mass media and communication. The sense for fashion is liable to change according to the circumstances and, simulated world is made. -The sense of denial is not shown much to the western lifestyle and way of thinking owning to the international open culture. Their consciousness and favorite of fashion are beyond the border. The new generation showed the unprecedent way of expression, denying the established form, and this is defined as Borderless fashion. The Borderless fashion leads a whole trend of new generation's fashion in the late part of ninties. Two typical trends appear as Genderless look for the individualic group and Romanticism look laying stress on womanliness.

With the increasing demand for enzymes in industrial applications there is a growing need to easily produce industrially important microbial enzymes. This study was carried out to screen the indigenous refinery bacterial isolates for their production of two industrially important enzymes i.e. lipase and protease. A total of 15 bacterial strains were isolated using Soil Extract Agar media from the oil-contaminated environment and one was shown to produce high quality lipase and protease enzymes. The culture conditions (culture duration, temperature, source of nitrogen, carbon, and pH) were optimized to produce the optimum amount of both the lipase (37.6 ± 0.2 Uml-1) and the protease (41 ± 0.4 Uml-1) from this isolate. Productivity of both enzymes was shown to be maximized at pH 7.5 in a medium containing yeast extract and peptone as nitrogen sources and sucrose and galactose as carbon sources when incubated at 35 ± 1℃ for 48 h. Bacterial strain SAB06 was identified as Bacillus licheniformis (MT250345) based on biochemical, morphological, and molecular characteristics. Further studies are required to evaluate and optimize the purification and characterization of these enzymes before they can be recommended for industrial or environmental applications.

The ecological expression of art in modern society takes the harmonious developmental relationship between man and nature as an element and combines it with the various manifestations of painting as an expression of ecological artistic development. The necessary relationship for the harmonious development of nature is accurately articulated, and the ecological changes in people are expressed in integrated materials that inspire human reflection. In the pursuit of material pleasures, mankind is neglectful and indifferent to the environment. The development of composite painting in art and ecology is a process that more reveres the harmony between man and nature as well as satisfying the creative value of the work. After systematic evaluation and research, people have engaged in various structural forms of composite art painting development in the long history of art development, focusing on the integration of environmental and ecological culture.In the process of nature education going through development, the comprehensive practical development of nature education is enhanced and efforts are made to feel new ecological art ideas and new ways of valuing environmental protection. In this paper, an observational study of eco-art will be carried out, starting from the theory of hierarchical division and analyzing the contradictory relationship between man and nature. Recognize nature, understand it and feel it through eco-art painting. The analysis of the contradictory relationship between man and nature is combined with the identification of various types of information that give value to the environmental protection public, and the combination of ecological painting and nature art to achieve an upgrade of the environmental protection idea of the value of painting.

The emergence of environmental and social issues has led to global discussions for the realization of sustainable development. The purpose of this study is to propose a method of sustainable fashion design using waste Hanbok, focusing on men's Hanbok with cultural values. The study utilizes literature research and fashion design development. From the literature study, reform was judged to be a higher concept encompassing reduction, recycling, and upcycling. Reduction is a design method through removal, and recycling design transforms from its original form into a completely different product. Upcycling design focuses on improvement and change in functionality. Accordingly, nine redesigns using men's Hanbok were developed from which three were produced. Consequently, the reduction design demonstrated a small range of variation without changing the item, and cultural sustainability was confirmed through the design that removed the components and recombined the Hanbok. Second, recycling redesign can be reconstituted into a different item. Third, upcycling enables various designs through module assembly, which prolongs the lifespan of the product and confirms its value as a raw material for waste Hanbok. This study is meaningful in realizing sustainable fashion and suggesting practical measures for the sustainability of Korean traditional culture and creative fashion design planning.

The Bacterial community structure and its complexity of the enrichment culture during the isolation and screening of imidacloprid-degrading strain were studied using denaturating gradient gel electrophoresis analysis. The dominant bacteria in the original tea rhizosphere soil were uncultured bacteria, Rhizobium sp., Sinorhizobium, Ochrobactrum sp., Alcaligenes, Bacillus sp., Bacterium, Klebsiella sp., and Ensifer adhaerens. The bacterial community structure was altered extensively and its complexity reduced during the enrichment process, and four culturable bacteria, Ochrobactrum sp., Rhizobium sp., Geobacillus stearothermophilus, and Alcaligenes faecalis, remained in the final enrichment. Only one indigenous strain, BCL-1, with imidacloprid-degrading potential, was isolated from the sixth enrichment culture. This isolate was a gram-negative rod-shaped bacterium and identified as the genus Ochrobactrum based on its morphological, physiological, and biochemical properties and its 16S rRNA gene sequence. The degradation test showed that approximately 67.67% of the imidacloprid (50 mg/l) was degraded within 48 h by strain BCL-1. The optimum conditions for degradation were a pH of 8 and $30^{\circ}C$. The simulation of imidacloprid bioremediation by strain BCL-1 in soil demonstrated that the best performance in situ (tea soil) resulted in the degradation of 92.44% of the imidacloprid (100 mg/g) within 20 days, which was better than those observed in the ex situ simulations that were 64.66% (cabbage soil), 41.15% (potato soil), and 54.15% (tomato soil).
