As the environment related to hospital operation has changed very competitively in recent years, a need to reform the hospital management is ever growing. For that reason, it has become more urgent and strategically important for us to diagnose the organizational culture of the hospitals and to make efforts to change them towards more performance- and customers-oriented one. So far, there have been many studies done on the hospital organizations. However, this research distinctively attempts to base itself on the competing values approach in studying the organizational culture and empirically examine how different profiles of the organizational culture may have an impact on the organizational performances in hospital organizations. The results of this study has showed several interesting findings and posed the discussions to be dealt with. First, most hospitals selected for this research are characterized by the inner-oriented culture with more focused on 'hierarchy' and 'relationship-oriented' culture rather than on 'reform' and 'work-oriented' one. And the strong 'hierarchy-oriented' culture is a very general phenomenon in the sample hospitals. From these findings, we can inference that despite the recent efforts of most Korean hospitals for organizational change and innovation they still have long distance way to go. In addition, another important implications of this research has come from the analysis of the relationships between the cultural profiles and organizational performances. For this purpose, this research has conducted a series of cluster analysis and identified four distinct cultural profiles from the sample organizations. Several major findings are as follows. First, with respect to the dependent variable of 'job satisfaction' perceived by the nurses working in the sample hospitals, we found that the balance of competing organizational values had more positive impact on the job satisfaction. This result confirms the hypothesis of competing values model on the organizational performances. However, such result was not replicated on the other dependent variable, 'patients' satisfaction'. The reasons for these results and other discussions including the limitations of this study are suggested.

This study aimed at developing an educational program for South Korean adolescents on North Korean family living culture so that the students become familiar with the values and everyday lifestyles of North Korea. Understanding of North Korean culture is considered important as a foundation for social integration in prospect of future reunification. The contents of the program were developed based on the analysis of North Korean defectors' interviews and review of the literature and media reports on North Korean family culture. The program consists of 12 units of 40-minute sessions with the following topics: economy and consumption, leisure activities, family relationships, dating and spouse choices, fashion changes, clothing acquisition and care, food choices and local diets, dietary problems, housing, and neighborhood. The program was implemented between December 21 and 30, 2015 in a middle school located in Seoul. This program is expected to be useful in preparing the students as future leaders to create harmonious family living culture in the reunified Korea.

Shrimp farming is the most important mariculture industry on the west coast of South Korea. However, it has suffered from mass mortality due to viral disease outbreaks and coastal pollution due to water discharge. This study developed an intensive shrimp culture method for outdoor ponds, without water exchange, which minimizes the chance of viral transmission from the environment, reduces coastal pollution by water discharge and enhances shrimp production. A culture trial was conducted in two high-density polyethylene (HDPE)-lined ponds with a $550\;m^2$ surface area. The ponds were stocked with postlarvae of Litopenaeus vannamei, the major farmed shrimp species in Korea, on July 10, 2007, and cultured for 90 days with no water exchange. The stocking density of the postlarvae (B.W. 0.0015 g) was $272\;ind./m^2$, which is eight times higher than in traditional pond culture in Korea. At harvest, the total production of ponds 1 and 2 was 1,362kg ($2.48\;kg/m^2$) and 1,282 kg ($2.33\;kg/m^2$), respectively. This is 20~22 times higher than the mean farmed shrimp production ($0.112\;kg/m^2$) in Korea and about eight times higher than in traditional ponds with a good harvest. Although there was no water exchange throughout the culture period, the mean concentrations of unionized ammonia and nitrite-nitrogen were as low as 0.038 and 6.0 mg/L, respectively. The feed conversion rate (FCR) was 1.38, which is 20~45% lower than that of traditional pond cultures. The high efficiency of the diet in this study is thought to be due to a well-managed feeding strategy and well-developed bioflocs used as diet additions for the shrimp. The final body weight of the shrimp at harvest was low (12.2~12.5 g), compared with that of traditional pond culture. This may have resulted from the combination of a short culture period, high density of shrimp, and low temperature. This study suggests that a super-intensive shrimp pond culture method using biofloc technology with no water exchange can minimize viral transmission via water exchange, reduce coastal pollution, and enhance shrimp production.

The purpose of this study is to examine how the entertainment culture has influenced the fashion of the college students since the year 2000, and to analyze the fashion trends of those who enjoy their entertainment culture. The entertainment culture is, therefore, perceived in the most sensitive way by the college students, who belong to the latter period of their adolescence, while influencing them. Especially recently, the entertainment culture of the college students has emerged as a new symbol of the overall fashion. And its effect on the fashion has become conspicuous. The 21st entertainment culture is comprised of "club culture", which is an off-line fad, and "on-line game culture". The result of this study is as follows: Firstly, the formative way that the so-called "club culture" influenced the fashion of the college students shows that their overall fashion trends are characterized by a 'caports image' and a 'childlike-amusing image'. Secondly, the formative fashion style, influenced by the so-called "on-line game culture", presents a 'post- structural image' by using heterogeneous material in order to introduce a new point of view, and by transforming the creation style and design. And it also presents a 'homosexual image' by crossing the attractiveness of both genders. This study is baseds on the documents study.

The effects of glycine on cell growth and L-omithine production were investigated in shake-flask and jar fermentor cultures of a citrulline auxotrophic mutant, Brevibacterium ketoglutamicum BK 1046. In the shake-flask culture, the optimal concentration of glycine for L-ornithine production was found to be 20 g/l. In the jar fermentor culture with the glycine at an initial concentration of 20 g/l, L-ornithine production increased by 28%, compared to that of the culture with no glycine added. 37 g/l of L-ornithine was produced when additional feeding of glycine (5 g/l) was made. This was a significant improvement in L-ornithine production compared to that (ca. 24 g/l) of the corresponding batch culture conducted without glycine. According to the stoichiometric analysis with the batch fermentation results, the experimental and theoretical L-ornithine yields based on the glucose consumption were 0.24 and 0.59, respectively. This indicates that the performance of L-ornithine fermentation can further be improved by the supplementation of glycine and the development of a mutant strain possessing a higher growth yield.

The purpose of this study was to investigate and conduct effective schemes to direct drama activities for three-year-old children and to examine its influence on them. This research subjects comprised 23 three-year-old children and 2 teachers attending classes at Gureum at SanDeul kindergarten in Seoul, Korea. The researcher first recognized that problems existed in the ways in which children's leading roles were limited by the actor's roles themselves and they therefore were constrained in their use of dramatic expressions while performing drama activities. The researcher also recognized that children's drama activities integrated with traditional culture were largely deficient. For more effectively direction of children's drama activities, action research method was conducted over two sessions. First, certain factors of plays and traditional culture were incorporated within children's drama activities. Second, certain factors of Madangguk and traditional culture were also incorporated within children's drama activities. Through undertaking this research project, children were given the opportunity to actively participated in drama activities, trained their range of imaginative expressions, improved their cooperation with peers and enhanced their interest in traditional culture. The research suggests that children's drama activities when integrated with plays and Madangguk could effectively enhance children's artistic and educational skill.

The effect of thinned fruits, apple, pear and peach, on the mycelial growth of mushrooms was investigated. The growth of mycelia with the addition of thinned fruit was clearly better than that in the control for all the tested mushrooms. The growth rate of Pleurotus ostreatus was faster than any other mushroom. The optimal concentrations of thinned apple, pear, and peach in a solid culture were 1.0%, 1.0%, and 3%, respectively, while in a liquid culture the optimal concentrations were 5,0%, 3.0%, and 5.0%, respectively. When Pleurotus ostreatus was incubated in a 20-L pilot scale fermenter with 10 L of a liquid medium containing 3% thinned fruit at 25$^{\circ}C$ and 6 vvm for 10 days, the mass-production of mycelia was 74.2 g/10 L (apple), 96.2 g/10 L (pear), and 86.3 g/10 L (peach). The mycelial yield of Pleurotus ostreatus in a medium containing thinned fruit was 2 ∼ 3 times higher than that in the control.

During dongchimi fermentation at 5 and $25^{\circ}C$, the pH lowered slowly and reached 4.03 at $5^{\circ}C$ after 30 days, whereas it lowered dramatically and reached 3.59 at $25^{\circ}C$ after 2 days. The predominant bacteria were Leuconostoc (Leu.) mesenteroides at $25^{\circ}C$ until day 2 which changed into Lactobacillus (Lb.) plantarum at day 3, analyzed by a culture dependent method with partial 16S rRNA gene sequencing, whereas Leu. mesenteroides occupied predominantly at $5^{\circ}C$ until day 7. In a culture-independent method using a polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) with partial 16S rRNA gene sequencing, Lb. algidus was predominant at $5^{\circ}C$ until day 7 and Lb. plantarum occupied predominantly at $25^{\circ}C$ until day 3, which is different from the results of the culture based method, indicating the both methods need to be combined for accuracy. Based on the culture-dependent method, Leu. mesenteroides might be responsible for the early and mid-phase of dongchimi fermentation.
