  • An antifungal antibiotic was extracted three times using n-butanol from the culture broth of Bacillus sp. Bioassayguided column chromatography with silica gel and Sephadex LH-20 yielded 62 mg of the original active compound from 1 L of culture broth. The minimal inhibitory concentration values were 25 and $50{\mu}g/ml$ against Pyricularia oryzae and Pellicularia filamentosa, respectively. Based on results obtained from the analysis of the structure of the antibiotic using MS, NMR, and IR spectroscopy, the antifungal antibiotic was shown to consist of only six of fructose.

  • The toxicity values heavy metals were evaluated by immobilization and chronic reproduction impairment tests, using Daphnia magna. Acute tests were evaluated by the inhibition of their mobilization after 24hrs without food addition. The tests of reproductive impairment were investigated for 21 days by food addition and exchange or water. The effect of each concentration was assessed by Probit analysis and t-test. The results obtained from this study were as follows : 1) The change of pH and DO was not significant in the acute tests, while, in the reproductive tests, pH was increased by 0.3~1.4 and DO also increased. 2) The $E_iC_{50}$ values of immobilization to Daphnia magna in artificial fresh water were $0.030mg/{\ell}(Cu),\;0.054mg/{\ell}(Cd),\;0.12mg/{\ell};(Cr),\;0.74mg/{\ell}(Pb),\;3.4mg/ {\ell}(As)$ and the $NOE_iC$ values were $0.010mg/{\ell}(Cu),\;0.018mg/{\ell}(Cd),\;0.010mg/{\ell}(Cr),\;0.10mg/{\ell}(Pb),\;and\;$1.8mg/{\ell}(As)$. 3) The $E_rC_{50}$ values of reproductive impairment to Daphnia magna were $13.8\mu\textrm{g}/{\ell}(Cu),\;2.9\mu\textrm{g}/{\ell}(Cd),\;15.5\mu\textrm{g}/{\ell}(Cr),\;61.7\mu\textrm{g}/{\ell}(Pb),\;759\mu\textrm{g}/{\ell}(As)$, and $NOE_rC$ values were $0.95\mu\textrm{g}/{\ell}(Cu),\;$0.54\mu\textrm{g}/{\ell}(Cd),\;1.2\mu\textrm{g}/{\ell}(Cd),\;$7.4\mu\textrm{g}/{\ell}(Pb),\;110mu\textrm{g}/{\ell}(As)$. The results of tests using OECD artificial culture water were more sensitive than natural water for culturing. The presented data show that an artificial culture water is suitable in the experiment of bioassay for assessing the toxicity of marterials.

  • This study examines the influence of fashion accessories on how men of different ages are perceived, as well as how the social values of the perceiver affect the image evaluation process. For the purpose of this study, men's accessories were limited to glasses, ties, and hats. A quasi-experiment was conducted in which 358 female university students in Seoul examined two men, one in his 30s and the other in his 60s. The social value included materialism and hedonism with higher and lower group. Factor analysis revealed three main factors with regard to men's image based on age and accessories: professionalism, morality, and preference. The findings indicated that wearing accessories can affect how men are perceived, and the perceivers' social values are at play throughout the process. Glasses enhanced a professional image in men, while ties amplified professionalism and morality. Morality and preference for the older man were heightened when he wore a fedora and a hunting cap. Taking social values into account, perceivers with a higher level of materialism associated a man with a navy blue tie more strongly with professionalism. Perceivers who possessed more hedonistic traits preferred a man wearing a cap. The subjects considered the man in his 60s as having a higher level of professionalism when he wore casual hats such as a cap or a cloche. The results of this study suggest that social values such as materialism and hedonism play a part in how people perceive men wearing accessories.

  • The focus of design in the contemporary point of view has changed from the improvement in production efficiency for profitability and in styling for sales promotion to human-oriented design. Human-centered design has developed into design which includes social and ethical responsibility and values. With tradition and culture as a base the principles of markets and capital are incorporated as well. Such current design is the outcome of design which honors social values represented based on culture acquired from individuals and society and the the responsibility of the designer who provides it. For the realization of social values in design, it should be considered along with the influence of design on society, this study presented the following cases: First, human-oriented design for those who are isolated, but should not be ignored; Second, cultural-oriented design which makes a contribution to local conditions; and third, usability-oriented design which replaces familiar ideas with new paradigms. This study presented the function and meaning of design in terms of purpose and the methods to solve social and human problems using design. Further studies should deal with the realization and extension of social values through design.

  • Housing can be defined as the vessel containing human life and each country has considerably different form and culture of it. This study aims to understand the society's common cultural values of house selection, decision making, an various housing issues. Consequently, applying a multidisciplinary approach, this project seeks to explore the correlations between people and housing, and between society and housing, to better understand the thought and culture of the housing residents. In order for doing it, adopting cultural value of housing as a tool, a comparative cultural study of housing values in East Asia starting from Korea and China will be conducted. Through such a comparative cultural study, it will be ultimately possible to grasp the locality and uniqueness of specific cultures with more clarity. A survey using questionnaire was conducted on 126 Korean Students and 145 Chinese students who are studying at K University in Seoul on a random sampling basis. The results of survey are as follow. Both Korean and Chinese college students gave higher values on neighborhood environment, convenience of transportation, privacy and safety, and to be given a higher value. On the other hand, they gave lower values on the symbolism of social status. Korean university college students gave higher considerations in the list of , , and than Chinese. Chinese college students gave higher consideration in the list of , and than Koreans. Even though this study has some limitations in generalizing the findings, we can understand the identity of Koreans and Chinese through the comparative study.

  • The aim of this study was to examine how customers perceive storytelling at a real local restaurant and to understand how consumption reflects their evaluation by understanding their values. Participants received information from a real local restaurant in the Gangneung area to examine the effects of storytelling and to evaluate their affective attitudes towards local restaurant stories, word-of-mouth intentions, and purchasing intentions using a seven-point Likert scale. A total of 310 consumers were used. A factor analysis was performed to identify consumption value characteristics and factor structure, which consisted economic value, emotional value, and epistemic value. To test whether local restaurant consumers could be classified into homogenous groups based on their consumption values, a three cluster solution was selected, and a Kmeans cluster analysis was performed. As a result, three groups were identified and labeled appropriate for their scores based on each of the consumption values; emotional value-oriented consumers to cluster 1, epistemic value-oriented consumers to cluster 2, and economic value-oriented consumers to cluster 3. An analysis of variance was used to examine the differences in the affective attitudes towards storytelling at the local restaurant, purchasing intentions, and word-of-mouth intentions across the three clusters. The epistemic value-oriented consumers had the highest score for all three variables. In contrast, economic value-oriented consumers had the lowest scores for the three variables. A regression analysis revealed that affective attitudes towards storytelling were significantly affected by these three consumption values. It also showed that positive affective attitudes towards storytelling were associated with higher purchasing intention and word-of-mouth. The significance of this study was to show how customers perceive storytelling at a real restaurant and reflect on their evaluation by understanding their consumption values. As a result, this study examined the potential power of storytelling as an effective marketing communication tool for local restaurants.

  • The purpose of this study was to determine the empirical cause-effect relationships among business ethical values and person-organization fit, job satisfaction, turnover intent, and organizational performance within family restaurants and feeding facilities. Self-administered questionnaires were completed by 459 restaurant employees. The SPSS and Amos programs were then applied to the data to perform frequency, factor, reliability, correlation and SEM analyses. The primary results are as follows. First, business ethical values had a significant positive effect on person-organization fit. Second, person-organization fit had a significant positive effect on job satisfaction, and a significant negative effect on turnover intent. Third, job satisfaction had a significant positive effect, and turnover intent had a significant negative effect, on organizational performance. Finally, upon verifying the possible direct and indirect effects of business ethical values within family restaurants and feeding facilities, it was determined that the ethical values had significant direct and indirect effects on person-organization fit, job satisfaction, turnover intent, and organizational performance. These findings have various implications. For example, an improved in-house ethical working environment leads to greaterperson-organization fit, and having employees that feel there is better in-house ethical reliability leads to greater consistency between personal and organizational values, resulting in higher job satisfaction and ultimately organizational performance.

  • This research examined the relation between personal history of residential moves and psychological independence. In particular, this research tested how actual self-importance (vis-a-vis perceived social importance) of values (Study 1) and preference for uniqueness (Study 2) would vary as a function of past experience of moving. The results showed that personal history of residential moves was positively linked to actual self-importance of individualistic values and perceived social importance of collectivistic values. In addition, the results demonstrated that individuals with frequent residential moves generally showed a greater liking for uniqueness. The implications of these results for the direction of causation between residential mobility and psychological independence are discussed and suggestions for future research are made.
