In this study, we intended to get a preliminary data for establishing rat tracheal surface epithelial(RTSE) cell culture system as an experimental model for physiology and pharmacology of tracheal epithelial cells. Primary culture on the membrane support and application of the air-liquid interface system at the level of cell layer were performed. The cell growth rate and mucin production rate were measured according to the days in culture. The results were as follows: this culture system was found to manifest mucocilliary differentiation of rat tracheal epithelial cells, the cells were confluent and the quantity of produced and released mucin was highest on culture day 9, the mucin was mainly released to the apical side and tbe free $^3{H}$-glucosamine which was not incorporated to process of synthesis of mucin was left on the basolateral side. Taken together, we suggest that air-liquid interface culture system can be used as a substitute for immersion culture system and as an experimental model for in vivo mucus-hypersecretory diseases.

Indonesia has the largest economy in Southeast Asia and is one of the fastest growing economies of the world. This study was conducted to understand Indonesian food consumers, and to provide the marketing implications for food exporting companies in Korea. An online survey was conducted on 795 local consumers in Indonesia and the study analyzed their preference for Korean food and Korean culture. Then this study identified the relationship of these variables and consumers' intention to purchase Korean food. The results of this study were as follows. First, Indonesian consumers had a strong preference for Ramyeon, noodles, snacks and kimchi among Korean foods. Second, the preference for Korean culture was high in a descending order of Korean dramas, cosmetics, songs and news. Third, both Korean food and Korean culture preferences showed significant differences depending on gender, age and the frequency of eating out. Lastly, analysis of the relationships among the variables showed that there is a positive relationship between Korean food preferences and Korean food purchase intentions. Further, the consumers' Korean culture preference had a mediating effect within this relationship. The results of this study imply that marketers in Korea food companies need to consider the consumers' preference for Korean food and Korean culture when they build proper strategies for exporting Korean foods to Indonesia.

This study looked at the factors that shaped the identity of the Bupo-dong community through Dong-gye and Sangyeo-gye, mainly in the case of Bupori, Yeah, and Adong, and to identify that Dong-gye and Sangyeo-gye, played an important role in shaping and strengthening the community culture of its members. As a result of his inspection, Bupo-dong formed and maintained his belonging and identity as a member of Bupo-dong through the Dong-gye, the town's autonomy code. We were able to confirm that bupo-dong, unlike other villages where community culture is largely destroyed, has been able to continue its own community culture as a bupo people to this day, with a sense of belonging, solidarity and intimacy through the Sangyeo-gye of cooperation and relief. And it can be seen that the fact that the Burawon space, which has symbolic meaning to the people of Bupo-dong, exists without being watered down. It is important to discuss the community culture of Bupo-dong, which is sustainable, mainly in Bura-dong, which continues to be an important cultural space for bupo-dong people to meet and town events.

Korea, China and Japan are countries located in Northeast Asia territory sharing similar natural environment. Countries are also using rice as a main diet material accompanied with vegetables, marine products and bean or fermented bean food. Yet, at the same time each country's food culture appeared as to be unique in food space due to their diverse food materials from different natural, cultural and religious background. This research is probing a way to recover subjective food culture and accomplish food environment which appropriates to modern globalized era by developing simple and economical repast tools meeting public's needs and distributing unique repast tools becomes Korean food culture and can be used in the life pattern of modernized nuclear families.

Alcoholic beverages can be viewed as repositories of historical information reflecting agricultural environment, economic and scientific level, religion, literature and art of their country. Korean Alcoholic beverages are based largely on rice, which have been developed in the following order: Takju, Cheongju and distilled spirits, Soju. They are closely related with the development of agriculture and historical levels of science and technology, and thus can be seen as symbolizing economic and political changes as well as rises and declines throughout the culture's history. The present review assessed the past and present flows of Korean alcoholic beverage culture, which has had a significant influence on the mental world of Korean people, based on literature concerning the history of food in Korea. Another focus of the study was a discussion on the future transmission and refining of Korean alcoholic beverage culture, which is undeniably informed by the Korean people's unique imagination and cultural sense.

A perfusion culture of transgenic Nicotiana tabacum cell suspensions, transformed to express recombinant glucuronidase (GUS), was successfully performed in a 5-1 stirred tank bioreactor. With 0.1 $day^{-1}$ of perfusion rate, the maximum dry cell weight (DCW) reached to 29.5 g/l in 16 days, which was 2.1-fold higher than the obtained in batch culture (14.3 g/l). In terms of the production of GUS, the volumetric activity could be increased up to 12.8 U/ml by using perfusion, compared with 4.9 U/ml in batch culture. The specific GUS activities in both perfusion and batch cultures were maintained at similar levels, 200-400 U/g DCW. Consequently, a perfusion culture could be a good strategy for the enhanced production of recombinant proteins in a plant cell culture system.

This research is about the pulsatile pump system utilized in the perfusion bioreactor for the in vitro human tissue culture. A pulsatile pump system which can be applied to the culture of the vascular tissues including blood vessel is developed by using the idea of human heart's blood pumping into organs as followings: culture chamber, a pressurizing device which generates laminar pulsatile flow by controlling the x-sectional area of the culture media delivering tubing, a compliance chamber which supplies the pressuring device with a constant pressure, and a peristaltic pump which circulates the culture media in a circuit ranging from the culture chamber to the compliance chamber. The developed pulsatile pump system shows that a physiology of the human heart's blood pumping including pulsatile pressure waveform of systolic-diastolic pressure is well represented. Not only time domain but also frequency domain characteristics of pulsatile pump system which are necessary for the vascular tissue culture such as pulsatile pressure waveform's shape, the frequency, and the magnitude can be easily generated and manipulated by using the proposed system.

Purpose: This study aimed to identify the effects of organizational culture, organizational silence, and organizational commitment on the intention of retention as perceived by nurses Methods: The research model was designed on the basis of the PROCESS Macro model 6 proposed by Hayes. The participants were 142 nurses from general hospitals. Measurements included the scales of organizational culture, organizational silence, organizational commitment, and intention of retentione. Data were analyzed using descriptive statistics, Pearson's correlation coefficient analysis, and Hayes's PROCESS macro method for mediation. Results: Retention intention showed a significantly positive correlation with relationship-orientated culture (r=.32, p<.001), innovation-orientated culture (r=.30, p<.001), and organizational commitment (r=.48, p<.001). However retention intention showed a significantly negative correlation with organizational silence (r=-.42, p<.001). Furthermore, organizational silence and commitment had a mediating effect on the relationship between organizational culture and intention of retention. Conclusion: The impact of organizational culture on intention of retention in general hospitals was mediated by organizational silence and organizational commitment. Considering the mediating effects of organizational silence and organizational commitment on the relationship between nursing organizational culture and retention intention, a strategy should be developed to enhance organizational commitment and weaken organizational silence by strengthening related and innovative nursing culture.
