Aspergi11us niger F-580, a potent producer of aminopeptidase M inhibitor, was isolated from the brown spots of plant leaves with a pathological trait. The inhibitory activity was found only in the fungal mat formed by surface culture of Aspergi11us niger F-580, but not in the culture supernatant or cell pellet. The inhibitor was purified from the hot water extract of this fungal mat by using chromatographies on Diaion HP-20, DEAE-cellulose, Sephadex G-l0 and YMC-ODS-AQ columns. The purified inhibitor was analyzed by UV, mass, and NMR spectroscopies, and identified as OF494911, which had been isolated as an aminopeptidase B inhibitor from Penicillium rugulosum OF4949

Department store has actively expanded cultural center services by providing a series of educational courses in order to increase customer visits, enhance customer satisfaction, and ultimately increase sales. In this study, cultural center members' shopping behaviors and image building of the department store were explored through focus group interviews. Results generated from a total of 7 focus group interviews with female cultural center members in their 30's through 60's are as follows. First, the consumer group who attends courses for their own purpose is 45 to 55 year-old female customers who are actively involved in consumption at the department store for their own clothing, food and restaurant. They are not often engaged in impulsive either group shopping for clothing. They are satisfied with class quality compared to low tuition whereas dissatisfied with busy schedule of a lecture room and lack of special discount benefits for members. Second, the other consumer group who attends courses for their children is consumers in their 30's. They are charged in shopping for clothing for their husbands, children, and themselves. They are suffering time poverty due to nurturing their children, therefore, they want to shop more in the department store on the day of class. However, expensive kids-care facilities are barriers to do it. Convenience, familiarity and center of culture are important images of the department store, developed through frequent visits of these customers. Eight implications for marketing strategies were generated based on study results.

Psychological support is crucial in navigating one's academic and professional lives, especially for students living abroad and pursuing higher education. This study aims to explore the narratives of social support seeking in a group of Korean international graduate students in an urban university setting in the United States. Qualitative research method of narrative approach was used to examine how three Korean graduate students exchanged psychological support. Analysis of interviews, observations, and documents found that four types of social support (informational, instrumental, appraisal, and emotional) were being exchanged and that emotional support was accessible predominantly in individual meetings than in group gatherings. Additionally, the reasons for abstaining from initiating group gatherings are discussed in relation to the Korean culture where participants were mindful of not infringing on each other's time. These findings inform theory on socio psychological support seeking and its relation to cultural values and offer practical insights into psychological support in international students in higher education settings.

Somatic cells such as oviduct epithelial cell, uterine epithelial cell, cumulus-granulosa cell and buffalo rat river cell has been used to establish an effective culture system for bovine embryos produced in in vitro. But nitric oxide (NO) metabolites secreted from somatic cells were largely arrested the development of bovine in vitro matured/ in vitro fertilized (IVM/IVF) embryos, suggesting that NO was induced the embryonic toxic substance into culture medium. The objective of this study was to investigate whether BOEC co-culture system can ameliorate the NO-mediated oxidative stress in the culture of bovine IVM/IVF embryos. Therefore, we evaluated the developmental rate of bovine IVM/IVF embryos under BOEC co-culture system in the presence or absence of sodium nitroprusside (SNP), as a NO donor, and also detected the expression of growth factor (TGF-$\beta$, EGF and IGFBP) and apoptosis (Caspase-3, Bax and Bcl-2) genes. The supplement of SNP over 5 uM was strongly inhibited blastocyst development of bovine IVM/IVF embryos than in control and 1 uM SNP group (Table 2). The developmental rates beyond morulae stages of bovine IVM/IVF embryos co-cultured with BOEC regardless of SNP supplement (40.4% in 5 uM SNP+ BOEC group and 65.1% in BOEC group) were significantly increased than those of control (35.0%) and SNP single treatment group (23.3%, p<0.05: Table 3). The transcripts of Bax and Caspase-3 genes were detected in all experiment groups (1:Isolated fresh cell (IFC), 2:Primary culture cell (PCC), 3:PCC after using the embryo culture, 4: PCC containing 5 uM SNP and 5: PCC containing 5 uM SNP after using the embryo culture), but Bcl-2 gene was not detected in IFC and PCC (Fig. 1). In the expression of growth factor genes, TGF-$\beta$ gene was found in all experimental groups, and EGF and IGFBP genes were not found in IFC and PCC (Fig. 2). These results indicate that BOEC co-culture system can increase the development beyond morula stages of bovine IVM/IVF embryos, possibly suggesting the alleviation of embryonic toxic substance like nitric oxide.

How consumers perceives Korean heritage is the most essential motivation to purchase traditional products. This study investigates if there is a difference in the value perception of traditional culture on preferences for and the long-term relationship of Hanboks. It also investigates differences in the preference and consumption behavior of Hanboks depending on the degree of experience for Hanbok. For this research purpose, data were collected from 745 residents between the ages of 20-60 in the Seoul and metropolitan areas through online and offline surveys. The data were analyzed by descriptive statistics, factor analysis, and path analysis, using the SPSS-WIN 20.0, AMOS 20.0 program. The value recognition toward traditional culture derived aesthetic and symbolic factors. The result of grouping according to the experience of the Hanbok indicated that the two groups of traditional cultural values influenced preferences for Hanboks. In the middle group, only the symbolic value had a significant influence on the preference of Hanbok. It was found that the less experienced group had no traditional culture value factor which had a significant effect on the preferences for Hanboks. Based on the results of this study, it is expected to be used as basic data to establish a marketing strategy to increase the preferences for traditional culture such as Hanboks by increasing various traditional culture experiences as well as Hanboks.

The government operates autonomous safety management activities in the regulated safety management in order to prevent industrial accidents. On the other side, companies are promoting safety management in the workplace, such as improving the safety level of the safety system, but the major reason for the accidents is safety ignorance in the event of big accidents. This study aims to improve the safety culture level by analyzing the difference in safety culture among six workplace sites in the manufacture of food products and drawing the improvement point. The main result is as follows. In order to enhance the safety level of the safety system, it is necessary to minimize the number of systems to be implemented, and to strengthen the small safety management activities that workers participate directly in the workforce, and the incentive policy for the promotion of the safety management activities should be coordinated by each group. Due to the high proportion of female workers, the proportion of female workers should be encouraged to actively participate in the safety of women, thereby improving safety culture levels and improving safety awareness through customized safety education. By learning work procedures through theory and practice, the level of safety culture should be increased. Employees voluntary safety participation activities should increase the level of mutual safety culture. Depending on spontaneous safety participation activities, one should promote safety culture enhancement activities by enhancing the safety level of the safety culture and enhance safety culture through safety awareness, and promote safety culture and procedures for improving safety culture.
