In this experiment, we tested various nitrogen sources and then culture condition was optimized for industrial applications. The batch culture of Candida magnoliae SR101 grown in a defined medium supplemented with light steep water (LSW) as a sole nitrogen source showed a relatively high yield of erythritol production (53%), which was slightly higher than that using yeast extract as a nitrogen source, while the productivity and cell mass were maintained at similar levels. For the optimization of culture condition, the batch culture was performed. When the concentration of LSW was 65 mL/L in the defined medium containing 250 g/L of glucose, the concentration, yield and productivity of erythritol were 110 g/L, 44%, and 0.66 g/L-hr, respectively. The high yield and comparable productivity obtained with a cheap nitrogen source could be expected as a basis for the mass production of erythritol in the industrial scale.

The purpose of this study was to identify the perceptional dimensions and patterns of Korean traditional food and to find the determinants of the patterns. Data were collected from 305 Korean housewives living in Mongol, and were factor and cluster analyzed. The results revealed two different dimensions and patterns i.e., high involved vs. low involved groups. Descriptive statistics showed that perceptional pattern types are likely to vary depending on socio-demographic and cultural background of Korean traditional food. Similarities and differences in perceptional patterns between high and low involved groups of Korean Mongolian are discussed, and future implications for globalization of Korean traditional food culture are provided.

Callus and cell suspension cultures of Eurycoma longifolia Jack could be an alternative supply of 9-hydroxycanthin-6-one and 9-methoxycanthin-6-one. The callus tissues were initiated from leaves of different trees. The friable calli were used for the preparation of the cell suspension cultures of E. longifolia. The leaf explant of tree Eu-9 produced the most callus and also induced high cell biomass in the cell suspension culture, but it produced low quantity of 9-methoxycanthin- 6-one and 9-hydroxycanthin-6-one. The leaf explant from tree Eu-8 produced low quantity of callus and cell biomass, but produced the highest quantity of 9-methoxycanthin- 6-one and 9-hydroxycanthin-6-one. Optimum production of cell biomass was obtained on cell culture medium with pH 5.75 prior to autoclaving, but high alkaloids content could be induced in culture medium in acidic condition with pH 4.75 and 5.25 prior to autoclaving.

To establish the optimal culture systems for production of transferable embryos in Korean Cattle, pregnancy rates of IVF-derived blastocysts according to different culture media, culture method and culture duration were compared. Development of IVF-derived embryos to blastocysts was most effective in YS medium group co-cultre with cumulus cells. Blastocysts cultured for 6 to 8 d in vitro showed higher hatching rate and good quality. Pregnancy rates after transfer of IVF-derived blastocysts cultured for 7 or 8 d were high. Through our experiments, it is considered that improvement of culture media and culture method is necessary for mass production of blastocysts with excellent of good quality in Korean Cattle.

The purpose of this study is to investigate the relationship between organizational culture types and organizational effectiveness in the hospitals and to identify the cultural and organizational characteristics of the hospitals with high organizational effectiveness. Data were collected from May 12 to June 14. 1997 through questionnaire taken by 1.118 nurses working in 10 hospitals with more than 800 beds and from annual reports published by the hospitals. The instruments were used for collecting the data: Organizational Culture Questionnatire and Organizational Characteristics Questionnatire developed by the researcher. Mowday's Organizational Commitment Questionnaire. Taylor & Bovver's General Satisfaction Scale. The Results were as follows: 1. The meta culture of the hospital organizations was the conservative culture. 2. There were significant differences of the four organizational cultural types - affiliative culture. innovative culture. conservative culture. task culture among the hospitals(p=.00). 3. The hospital organizations were classified in to three cultural patterns. each of which had similar cultural composition. on the basis of the scores indicating the similarity and difference of the foul' organizational cultural types among the hospitals. The organization of each group represents conservative- dominant culture. innovative-dominant culture and competitive culture. 4. Nurses' organizational commitment and job satisfaction were significantly different among the cultural patterns(p=.00). In other words. the hospitals with innovative-dominant culture showed higher organizational commitment and job satisfaction than ones with conservative-dominant culture and competitive culture. And also. the growth rate of outpatients and inpatients were significantly different among the cultural patterns(p<.05). The hospitals with innovative -dominant culture showed higher growth rate of outpatients and inpatients than ones with conservative-dominant culture and competitive culture. 5. The hospitals with conservative-dominant culture and competitive culture showed higher level of centralization than ones with innovative -dominant culture(p=.00) And the hospitals with competitive and innovative-dominant culture showed higher level of communication than those with conservative-dominant culture(p=.00) Finally. the hospitals with innovative-dominant culture showed higher level of managerial strategy than those with conservative-dominant and competitive culture. among which the latter showed higher level of managerial strategy than the former(p=.00).

In order to obtain high density seed cells for biofiltration, we studied batch and fed-batch culture of P. putida. Studies were carried out to find optimum fermentation conditions such as pH, concentration of glucose and agitation speed. Specific growth rate of P. putida was dependent on agitation speed and a high rpm of 300 was necessary to carry out the efficient aerobic growth of P. putida. Specific growth rate was highest at pH 7. Feeding glucose and yeast extract continuously at the initial growth phase was the most effective way to get high cell density of P. putida.
