The influence of various culture conditions on growth and ginkgolides (GKA and GKB), and bilobalide formation in callus and suspension cultures of Ginkgo biloba were investigated. Callus induced from the leaf petioles exhibited distinct morphological and physiological responses. The cell biomass and ginkgolides content varied among the cell lines; brownish callus lines produced high levels of ginkgolides and bilobalide in spite of poor cell growth. Among the culture media used, MS medium showed significant effect on cell growth and ginkgolides production. Low concentration of sucrose (3%) improved cell growth, while higher sucrose levels (5 and 7%) improved ginkgolides production. Cultivation of callus cultures above 28$^{\circ}C$ dramatically reduced their growth rate; however the cell lines grown at 36$^{\circ}C$ showed increased levels of bilobalide content. A 2.5-L balloon type bubble bioreactor (BTBB) was successfully developed for the cell growth and ginkgolides production.

The purpose of this theses is to review Hanliu phenomenon, a kind of social and cultural phenomenon, in China around A. D. 2000 in the view of the culture-diffusion theory, and analyze its effect to the fashion style of the new young generation of China. In this theses, Hanliu phenomenon means the enthusiasm of Asian people for Korean mass cultures such as Korean dramas, pop songs and fashions from late 1990's. This research adopts two kinds of methods for analyzing Hanliu phenomenon: a qualitative research method and a quantitative one. As a qualitative research method, we analyzed Hanliu phenomenon with several sources of documentaries and audio-visual materials on it. As a quantitative research method, we conducted a survey of about 100 university students in Beijing for how they feel of korean culture and fashions. The Hanliu phenomenon leads to the popularity of Korean products and the general Korean cultures. Also, it affected the Chinese young generation so much that the Korean fashion becomes popular among them. Its effects to the fashion styles of Chinese youths can be summarized in three factors as follows. Firstly, the fashions of Korean entertainers such as H.O.T hair style and Hip-hop fashion style are widely imitated. Secondly, the preference of Korean fashion products has been widely increased. The number of stores dealing with Korean fashion products has been increased. Finally, Korean culture and products have actively been imitated in China according to the increased popularity of Korean fashion products.

The shoot tip and young leaf of Rhodiola sachalinensis were cultured to invest the plant growth regulator condition for callus induction, shoot and root regeneration. When the shoot tip was sterilized in 2.0% of NaOCl for 20min., the contamination rate was the lowest. And the survival rate of the culture material was good in carbenicillin 500mg/L treatment group. Callus was obtained from shoot tip and young leaf segments. NAA 0.1-1.0mg/L and 2,4-D 0.1-0.5mg/L alone treatment were shown to have a good response on callus induction from shoot tip culture. In the case of young leaf culture, NAA and 2,4-D 0.1-0.5mg/L alone treatment were good in callus induction. In culturing shoot tip NAA 0.5mg/L and BA 0.5mg/L, NAA1.0mg/L and BA 0.lmg/L combination treatment was good in shoot regeneration. The regenerated shoots were rooted on MS medium supplemented with NAA and BA combination treatment. Especially, NAA 1.0mg/L and BA 0.1mg/L combination treatment was effective for root regeneration.

In the EFL context, Korean students don't have enough opportunities to directly experience the target culture, prompting the need to offer some well-organized culture education in class. The goals of this study are to analyze how many cultural contents are reflected in High School English textbooks and to suggest an implication for cultural learning. These textbooks were carefully examined, focusing on the cultural contents, by four categories: 'cultural skill section', 'cultural patterns', 'related language skills', and 'target countries'. The results of the analysis were like the following: First, although many of the textbooks are dealing with the culture skill sections, their contents were still wanting consistency and were small in quantity. Second, as for the cultural patterns, the pages dealing with behavioral culture were 43%, spiritual culture, 35.7%, material culture, 21.3%. Third, as for the related language skills, the cultural contents in the textbooks were organized in the order of listening, reading, speaking, writing, and cultural skill sections. Since it is impossible to separate language skills from culture, we suggest that the aspects of target culture should be incorporated in various forms into the learning situations. Fourth, as for the issue of target countries, the contents about the general or whole English culture were insufficient. So we suggest that English textbooks should play an essential role in providing students with various cultural information about various English speaking countries.

This study focused on concretely how minority group's attitude accepting han-zu's culture changes. In the past, minority group's culture and han-zu's culture were acculturated spontaneously, not forcibly. But as the people's republic of china was founded and control of chinese government was intensified, control and interference of minority group area became aggressive, and acculturation became compulsory. However, after chinese economic reform, by economic affluence and modernization and urbanization according to economic affluence, acculturation of minority group's culture and han-zu's culture is changing from forced acculturation to spontaneous acculturation. Still there are some areas where mutual friction lasts because of forced acculturation. But except some areas the stream is changing rapidly to spontaneous acculturation. In the text, this study investigated process and present state of acculturation focused on hui-zu that implemented aggressive acceptance of han-zu's culture relatively early. Then this study investigated yi-zu society and cultural change focused on their spontaneous acculturation. In the modern society setting a high value on convenience and personal happiness rather than ideology and value, value of race becomes less attractive to young people of minority group who know modern civilization and convenience of city. In this respect, maybe hui-zu society is future of yi-zu society and minority group society.

Purpose: The study examined the effects of personality factors and the perceived nursing organizational culture on workplace bullying of nurses. Methods: The participants were 110 allied general hospital with more than 300 beds. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and stepwise regression analysis with the SPSS program. Results: Workplace bullying differed significantly by marital status (t=-2.43, p=.017) and clinical career (F=3.82, p=.012). Statistically significant positive relationships was observed between workplace bullying and hierarch-oriented culture (r=.24, p=.031), and task-oriented culture (r=.26, p=.006), negative relationships was observed between workplace bullying and relationship-oriented culture (r=-.37, p<.001), and Innovation-oriented culture (r=-.24, p=012). A total of 23.7% of workplace bullying was explained by clinical career and relation-oriented culture. Conclusion: These results could be used in the development of workplace bullying preventive programs and caring programs for nurses considering clinical career by focusing the organizational efforts on relationship-oriented culture creation.

The purpose of this study was to optimize the conditions of continuous mixed culture of C.butyricum and R. spaeroides K-7, which were able to produce hydrogen using biomass-dreived substrate. To investigate the possibility of continuous culture, semi-continuous culture was carried out for 20 days. In semi-continuous culture using the reactor system, the replacement rate of fresh medium was 30% of total medium volume for the highest hydrogen evolution. In continuous culture, the optimum dilution rate was determined to be 0.05$h^{-1}$. The continuous culture produced 3.1 times as compared with the hydrogen on batch culture. On the other hand, the continuous mixed culture produced 1.3~2.1 times as much as hydrogen of the continuous monoculture of C. butyricum. When 10g of glucose in the media (1l) was supplied as a carbon source on continuous culture, mixed culture of C. butyricum and R. sphaeroides K-7 increased hydrogen evolution rate. Because considerable amount of glutamate was contained in waste water of glutamate fermentation, utilization of glutamate was examined in mixed culture. As a result of examination, production of hydorgen was slightly inhibited by high concentration of glutamate, more than 20mM, on continuous monoculture of R. sphaeroides K-7. On the other hand, both on continuous monoculture of C. butyricum and on mixed culture of C. butyricum and R. sphaeroides K-7, production of hydrogen was not inhibited by high concentration of glutamate such as 100mM. Hence this suggests that high concentration of waste water can be used as good substrate for hydrogen production on monoculture of C. butyricum and mixed culture of C. butyricum and R. sphaeroides K-7.

This study was conducted to compare various culture methods and evaluate economic feasibility of each method for mass propagation of new ever-bearing strawberry 'Goha'. Four different methods such as semi-solid culture, solid culture, liquid suspension culture and bioreactor culture were compared. The solid culture and bioreactor culture showed the shortest and longest root length, such as 3.6 cm and 8.3 cm, respectively. Fresh weights of plants cultured in bioreactor were 2,261 mg, which were heavier than those of cultures. Dry weights of plants cultured in bioreactor were the heavier compared to those in other cultures. The number of axillary bud developed in bioreactor was seven, but axillary bud was not developed in other cultures. Production cost through bioreactor culture was calculated to be 303 won per plant which was 542 won less than that of solid culture. As a result, we found that the bioreactor culture was the most cost effective culture method for in vitro mass propagation in new ever-bearing strawberry 'Goha'.
