An efficient method to produce water-soluble polysaccharides from Lentinus lepideus is described. The productivity of both endopolysaccharides (PPS) and exopolysaccharides (EPS) was compared under various culture conditions. The effect of treating their own PPS and EPS on immune cytokine production was also studied in relation to culture factors. High yield production of EPS required a moderate culture temperature $(25^{\circ}C)$ as well as long culture period (16-20 days). In contrast, PPS production required a high culture temperature $(30^{\circ}C)$ and short culture period (8 days). Most of the carbon sources did not affect polysaccharides and mycelial production except for sucrose. Immune cytokine levels in the EPS treatment varied among carbon sources or culture periods. PPS did not appear to affect much on the production of cytokines, regardless of the culturing factors, except for the culture period. These results suggest that the optimal culture conditions for L. lepideus vary according to culture purposes, and different culture conditions should be used for different targets including mycelial biomass, EPS, and PPS. Whereas the immunomodulating activitiy of EPS appeared to be affected by culture conditions in L. lepideus, that of PPS did not.

This study was conducted with the following three study objectives. First, effects of safety awareness level of lab researchers to the improvement of safety culture in the organization Second, effects of organizational safety behaviors to the improvement of safety culture Third, test of mediating effects of organizational safety behaviors in the relationship between safety awareness level and the improvement of safety culture. The results show that organizational safety behavior is an indispensable factor for the improvement level of safety culture. Especially, the factors in safety training activities, safety compliance and management system are mediating variables which affect the safety awareness level and improvement level of safety culture, which shows these variables are very important factors in reducing safety accidents through the improvement of safety culture. Therefore, safety behaviors in the organization should be considered with priority. If the organization leads to improve safety awareness through regular safety training and rewards and punishes according to the test results, safety awareness could be improved. This study was conducted to identify the necessary factors to improve the overall safety culture in the organization and contribute to the diffusion of safety culture by improving the safety training awareness of the researchers.

Korea has a dark age in terms of culture in the last 20th century. Korea had been struggling between the Great Powers of the world in the imperialism and had sacrifice to keep our own culture itself. Japanese imperialist's a invasion, culture liquidation by Japan, Independence from Japan, Korean war and Influence by US are major bitter historical affair after close of Chosun Dynasty in the process of modernization. Therefore Korea couldn't stay in the center of world cultural core parts and was degraded as cultural consumption country which was provided oversea culture by other countries. Then Korea couldn't develop our unique traditional idea and culture. In the meantime there are both extreme phenomena; one is expulsion of other cultures absolutely and the other is only following western culture unconditionally like trimming policy in the end of colony age. These discreet and unfiltered western culture had been influenced Korea culture over the wide range strongly and resulted in cultural colony situation to produce western imitation culture without philosophy and traditional spirit. Even though Korea has met opportunity in the culture, we called "Han Trend", no formation of own culture is main reason for psychological panic. Korea furniture design is one of parts of lost of tradition culture and typical parts in reproducing western imitation culture. As a result furniture industry's major reason for loss value as exporting industry compared to other industries result in most of the furniture products without our unique identity. This situation become more deepen unfortunately. This report would like to suggest the direction of design with global competition capability and cultural identity to boost Korean furniture design industry by comparing, analyzing and speculating between design of Chosun dynasty and philosophy of modernism in western.

Specialty contractor facilities, which involve a combination of welding and commissioning, face a high risk of serious accidents such as fire, explosion, and suffocation associated with welding work, nitrogen, and argon use. In such facilities, the organizational safety culture has considerable impact on the frequency of accidents. In this study, a safety culture evaluation was conducted on specialty contractors. NOSACQ-50, a standardized survey method on safety culture, was selected as an assessment tool to evaluate the safety culture in specialized construction companies that could not afford to invest heavily in safety. The self-administered questionnaire survey was conducted with 201 workers of four construction companies and the results were analyzed. It was found that in companies with low safety culture, the occurrence of irrationality was 66.0%, while in companies with high safety culture, the occurrence of irrationality was 42.6%. Thus, the difference in the occurrence of irrationality by safety culture was statistically significant. The difference in safety culture level according to the experience of occurrence of irrationality was also significant. It was also found that the higher the belief in safety management authorization, safety responsibilities of managers, worker safety priorities, and safety system effects, the lower the probability of irrationality.

This study was conducted to identify the general conditions for the isolation and in vitro culture of ovary-derived cells in rockfish (Sebastes schlegeli). The effects of three different enzymes on cell retrieval from ovarian tissues were evaluated first, and then the ovary-dissociated cells were cultured under various culture conditions, with varying basal media and culture temperatures, addition of growth factors, and/or culture types. We found that collagenase type I treatment was effective for cell isolation from ovarian tissues. From a total of 42 trials to evaluate the effects of basal media and culture temperatures on cell culture of ovary-dissociated cells, we observed that Leibovitz's L15 medium was more supportive than Dulbecco's modified Eagle's medium for culture, and the cells could grow at all three temperatures tested, 15, 20, and $25^{\circ}C$, at least up to passage 2. However, growth factor addition did not improve cell growth. Introduction of suspension culture after monolayer culture expanded the culture period significantly more than did monolayer culture alone. Our results may provide a basis for developing an in vitro system for S. schlegeli germline cell culture, which will ultimately lead to improvement of the species.

The study is aimed to analyse social and cultural background and to compare the changes of the cosmetic culture in Korea and the western countries accompanied by the developemnt os the cosmetic industry in the 20th century. The cosmetic culture of Korea has kept on changing adopting the new western style make up, These changes were very closely related with the current sociocultural environments and the developments of the cosmetic industry. The analysis and comparison of Korean cosmetic culture and that of Western countries can be summarized as following: Fistly the cosmetic culture of korea came out after Korean War through the improt of western movies. Secondly at the beginning of accommodation of the western concept of beauty the standards of beauty were confused with that of traditional make up. Thirdly in terms of the history of costumes in the western cosmetic culture the trend was feminine and curve lineal style in the 1910s straight and young style in the 1920s Young elegant curve lineal style and straight-line style replaced among themselves in every 10 years and the cycle became more rapid after the 1970s and there were diversity in the cosmetic culture affected by the postmodernism Fourthly the cosmetic culture of :total fashion" was taken into consideration. Fifthly the cosmetic culture of "total fashion" was taken into consideration. fifthly the make up of Korean and that of western countries are not only a way to express of aesthetic desire for beauty but sanitary management and it is a kind of an expansion of value for management for an inner self. Now is the time to refuse the attitude of accommodation of the western cosmetic culture without any consideration. We need to rediscover our traditional cosmetic culture and cultural distinctiveness and try to mix them with the western cosmetic culture in order to develop our own peculiar style which will be able to Korean design remain in the international stage and grow further.d grow further.
