  • Cultural conditions for $\alpha$-D-Glucosidase Inhibitor production from Streptomyces sp. YS-221-B isolated from soil arid identified as Streptomyces flauovirens or a subspecies of it were investigated. When the strain was cultured in a flask containing 2% glucose, 0.3% asparagine, 0.0002% riboflavin, 0.05% $K_2$HPO$_4$, 0.1% MgSO$_4$.7$H_2O$, 0.05% NaCl, pH 8.0 at 3$0^{\circ}C$, maximum production of the inhibitor was obtained after 8-9 days of cultivation. Sugar alcohols such as mannitol, i-inositol, erythritol as carbon sources, asparagine and beef extract as nitrogen sources were favorable for inhibitor production. Among vitamins, riboflavin, p-aminobenzoic acid, pyridoxamine and folic acid promoted the production of inhibitor, but depressed by the addition of hesperidine, and also depressed by cobalt, lithium and ferrous salts.

  • The purpose of this study was to analyze the environment of poverty children as reported by the children on a questionnaire. The conception of the environment was divided into the physical environment and the sociopsychological environment. The dimensions of the physical environment included household, cultural, and play conditions. The sociopsychological environment included structural (family values, family relationships, and the reinforcement system) and process variables(affect, care, and communication). For the purpose of this survey was administered to 122 children living in a poverty area and 102 children living in a middle-high income area. Statistics used for data analysis were frequency, distribution, percentile, mean and one-way ANOVA. Major findings showed that (1) The physical environment as reported by the poverty children was meager compared with that of children in the middle-high income area: the households were more overcrowded, and cultural conditions, play materials, and space was more limited. (2) The Structural conditions of the sociopsychological environment as perceived by poverty children were more material and physical than that of children in the middle-high income area: family values were oriented more toward materialism: family relationships were more negative and distant: and the reinforcement system was based more on material reward and physical punishment. (3) Process variables were perceived by poverty children as more laissez-faire and rigid; the parents neglected their children and communicated unilaterally more than the middle-high income parents. (4) Poverty children's perception of the causes of poverty and wealth were perceived as personal and social factors.

  • Purpose - The purpose of this paper is to advance the understanding of the relationship between host country image and cultural intelligence (CQ) on the attractiveness of expatriate destinations. Specifically, this study compares the different impacts of CQ on the relationship between host country image and subsidiary attractiveness by comparing a US-based subsidiary and a Vietnam-based one. Research design and methodology - A total of 445 Korean full-time workers responded through an online survey. The survey randomly showed the participants one of two conditions for a potential expatriate location. The participants were asked to answer a series of questions on the organizational attractiveness of the subsidiaries from the perspective of an expatriate candidate and respond to a series of questions on individual CQ. Results - Through a two-way ANOVA test, the results reveal that Korean expatriate candidates perceive that a Vietnam-based subsidiary is a less attractive destination for international assignment when compared to a US-based subsidiary. In addition, the positive moderating effect of cultural intelligence on the relationship between the host location and the subsidiary's attractiveness is stronger when Vietnam, rather than the US, is the assignment location. Conclusions - Drawing upon AUM theory, this study confirmed that unfavorable country image affects subsidiaries' attractiveness for expatriate candidates, due to anxiety. However, this study showed the role of employees' CQ to mitigate these challenges. This study suggests providing information on positive conditions of expatriate locations and building systematic process for enhancing individual CQ for organizations.

  • Rice Quality is considered to the five catagories ; the nutritional value: the characteristics of cooking. eating and processing: grain size, shape and appearance : milling yields: and storage characteristics. Because most rice is processed and consumed in whole-kernel form. the cooking and eating quality is of important and the physical properties of the intact kernel such as size, shape and general appearance are of particular significance in determining marketing quality. Eating Quality which can be directly evaluated by consumer's panel test is so complicate and variable, and thus the objective and simplified method of evaluation is required of using appropriate instruments. Even though many researches have been done to evaluate the eating quality in various aspects such as the texture of cooked rice kernels, amylogram analysis of rice powder, amylose content. gelatinization temperature. moisture absorption of rice kernel, and cooking characteristics, none of them is satisfied for the evaluation of eating quality. The improving eating quality should be also considered to many cultural factors. such as varieties, climatic and soil conditions, cultural method, handling after harvest. milling and storage conditions. In Korea, many researches in grain size. shape and appearance, and eating quality have been done with the varietal improvement mainly by rice breeders, but no effective method of evaluation was established. A few research have been done in the relationship between rice quality and cultural factors. In the future, research in rice quality should emphasize to establish the standard evaluation method in the physicochemical properties of rice kernels for application of varietal selection. and to develop cultural practices for the preserving quality characteristics of the varieties.

  • Old big tree transcends the simple meaning of trees as they are the natural monuments that embody the people's history and culture of this land. The Cultural Heritage Administration of Korea (CHA) defines and protects old big tree based not only on the size of the tree but also on its definitive cultural and natural factors such as value, implications, and originality. This research aims to identify and analyze the habitation and measurements, the soil conditions, as well as the protective facilities of 14 old big tree spread throughout the Gangwondo. The research examined the soundness of the arboreal form, the degree of damage on the bark, as well as the quantity of leafs levels to evaluate the overall condition of growth and development. Then, the tree height, the eastwest and south-north width of the crown, the sternum circumference, and the root circumference were recorded to identify the measurements of the selected old big tree. Also, the research analyzed 9 elements such as soil texture, pH levels, and organic contents in order to determine the scientific characteristics of soil upon which the trees draw nutrition. Finally, the research evaluated supporting pillars, lightning rods, iron pulling-facilities, as well as notice boards to study the protective facilities of old big tree. The research procedures revealed that 78.57% of the old big tree identified as natural monuments in the Gangwondo have average to above average habitation conditions. Also, the average tree height reaches 18.80m above ground while the average root circumference measures 7.34m. Moreover, the results of the scientific analyses conducted on the soil elements determined that most chemical values were within the defined levels, with the exception of phosphoric acid levels falling within the hyper-nutritious range. Finally, although most of the protective facilities did support the habitation of the Old big tree, there were some supporting pillars and iron pulling-facilities that actually damaged the trees. This research means to provide foundational reference data for the analysis of the habitation and management conditions of natural monument old big tree within the Gangwondo. A follow-up topic led by the results of this research is the identification and analysis of correlating environmental elements that affect the habitation of the old big tree.

  • The purpose of this study is to explore whether the perceptions of materialistic realities of South Korean university students can be explained by individual experience and media use. We examined: 1) relative consequences of awareness of discrimination experience and amounts of time spent on genre-specific media on perceptions of materialistic realities, 2) whether cultural orientation (allocentrism, self-monitoring, and masculinity) influences explanatory factors of awareness of discrimination experience, 3) conditions of countervailing responses to materialistic reality. As a result of analyzing the online survey data of 330 university students in Seoul, the amount of time spent on the beauty or fashion genre and awareness of discrimination experience explained the perceptions of materialist reality in Korean society. Although the perceptions that affected the accommodative response did not affect countervailing response, innovativeness had an interaction effect with perceptions of materialist reality in only countervailing response. Finally, the implications of these findings were discussed.

  • Understanding characteristics of Internet businesses from cross-cultural perspective could offer valuable insights on developing business strategy and policy. This work is concerned with revealing divergence and convergence of Internet business models in their financial performance, given organizational conditions and cultural context. For this, we studied the association between organizational attributes (core activity, origination, firm age, and industry) and their effects on a firm's financial performance (gross revenue and net income). Relevant data was gathered from representative Internet firms in Korea and U.S. Data analysis indicated that there exist both similarities and differences between Korea and U.S and year 2003 and 2006. While core activities and industry types of U.S. firms has not been changed much between the periods, Korean firms show much difference. In addition, while core activities and industry type were found to have strong relationship with financial performance, age and origination of a firm weak connections with financial performance. This study is expected to provide a foundation for developing more robust and systematic research model and performing further empirical research in this area.
