  • Angelica sinensis radix, Danggui, is a traditional oriental medication, which has been used to modulate immune response. We report here that aqueous extract of Angelica sinensis radix (ASR) can induces NO production, and inhibit LPS-induced NO production in dose-dependent manner in RAW 264.7 macrophage cells. ASR also induces iNOS mRNA and iNOS protein expression, and exhibit inhibitory effect on iNOS mRNA and protein expression in a dose-dependent manner in LPS-stimulated RAW 264.7 macrophage cells. Cytokines involved in the regulation of inflammatory reaction and immune response may play a role in the pathogenesis. ASR induces. pro-inflammatory cytokine gene expression (IL-1α, IL-1β and IL-6 gene) in a dose-dependent manner, and inhibits the expressions of these cytokines in LPS-stimulated RAW 264.7 macrophage cells. These data indicate that (1) ASR may be a potential therapeutic modulator of NO synthesis in various pathological conditions, and (2) the immunomodulatory effects of ASR may be, in part, associated with the inducing or suppression of pro-inflammatory cytokine gene expressions.

  • In this paper, we consider a renewal process in which both the inter-arrival times and rewards are fuzzy random variables. We prove the uniform levelwise convergence of fuzzy renewal and fuzzy renewal rewards. These results improve the result of Popova and Wu[European J. Oper. Research 117(1999), 606-617] and the main result of Hwang [Fuzzy Sets and Systems 116 (2000), 237-244].

  • This study analyses support policy and structural change of textile industry in Daegu Kyungbuk region, and suggests major issues for textile industry's innovation. In Daegu Kyungbuk, it was 1999 that a policy, so called Milano Project, in order to promote a textile industry was devised. In 2004, the Regional Industrial Promotion Plan was devised. The plan was born from a view point of establishing a regional innovation system and of promoting the innovative clusters under a knowledge based economy. After then, the Regional Industry Promotion Project or Regional Strategic Industry Promotion Project became a core of regional textile industrial policy. Research results indicated that the first stage Milano project (1999-2003) showed both positive and negative effects. There were no long-term development plan, clear vision and strategy. But, core industrial infrastructure for differentiated product development, such as New product Development Support Center and Dyeing Design Practical Application Center, was constructed. The second stage Daegu Textile Industry Promotion Plan (2004-2008) displayed a significant technological performance and new product sales with the assistance of Kyungbuk province. Also, textile industry revealed positive fruits such as financial structure, productivity, and profitability as a result of strong restructuring. In industrial structure, there was a important change from clothe textile material to industry textile material. Most of textile companies did not showed high capability in CEO's technology innovation intention, entrepreneurship, R&D and human resource competency in compare with other industry. We suggested that Daegu Kyungbuk has to select and concentrate on the high-tech textile material and living textile for sustainable development and competitiveness. We also proposed a confidence and cooperation based innovation network and company oriented innovation cluster.

  • This study was undertaken to compare the obesity related dietary factors among rural middle school students living in the Daegu.Kyungbuk area. Anthropometric data showed that mean height and weight were 162.7$\pm$8.6cm and 53.9$\pm$9.8kg in 220 male students and 158.4$\pm$6.2cm and 51.0$\pm$7.6kg in 210 female student. Mean BMIs for boys and girls were 19.00$\pm$2.35 and 19.30$\pm$2.45, respectively. 71.36% of male students and 71.9% of female students were underweight by the BMI index. Students who skipped the breakfast were up to 66.8%. The reasons for skipping a meal for both sexes were significantly different. Compared to males, more female respondents felt guilty and depressed related to eating. Furthermore, females were more significantly concerned about body image, diet and body weight (p<0.001), and they were not satisfied with their weight. The sources of information on obesity and diet were radio and TV in males, while females gathered information from magazines and friends. The ideal body weight of male students was heavier than the actual body weight while female students desired a thinner body shape. In conclusion, a different approach for nutrition education based on sex should be developed, and implemented fur adolescents.

  • Although copper and zinc are essential metals for human health, excessive level of these metals is toxic. Besides, aluminum is known to induce various adverse health effects including neurological disorders. Therefore, monitoring the human body burden of these metals is important in preventing adverse health effects. In this study, we assessed the exposure to copper, zinc, and aluminum among an adult population residing in Daegu and Kyungbuk areas. Based on data from 171 participants, we found that the geometric mean copper, zinc, and aluminum concentrations in hair were $15.1\;{\mu}g/g$ [95% confidence interval (CI): 13.1~17.5], 76.9 (95% CI: 70.4~84.1), and $1.11\;{\mu}g/g$ (95% CI: 0.81~1.51), respectively. The copper concentrations in hair were significantly related to age, education, and residence area. In addition, zinc concentrations in hair were significantly related to age, whereas higher hair aluminum concentrations were related to alcohol drinking. Correlations between copper and zinc in hair had a significant positive correlation. Our findings suggest that the body burden of copper, zinc, and aluminum varies according to demographic factors, and hair could be used as a valuable biological medium for metal exposure.

  • The purposes of this study were to investigate the degree of market orientation of textile firms and to explore the effect of market orientation on business performance and job satisfaction. The data were collected from 167 subjects who work at textile firms located in the Daegu and Kyungbuk province through survey. The collected data were analyzed by descriptive statistics, t-tests, correlation, regression, and structural equation modeling using AMOS 6.0. Market orientation has a significant and positive impact on the business performance as well as job satisfaction of employees in textile firms. In other words, the greater the market intelligence creation, the market intelligence dissemination and responsiveness of the organization, the greater the business performance. The greater these three factors of textile firms, the greater job satisfaction of employees. In addition, the relationships between company characteristics and market orientation were investigated.

  • The purpose of this study was to investigate the effects of eating habits and food preferences on the adoptive behavior of children with intellectual disabilities. Survey questionnaires were distributed to six special education schools located in the Daegu-Kyungbuk area, and data were collected from 552 families and teachers with intellectually disabled students. Identification of eating habits began with a factor analysis, and the results were a five-factor solution. Among the five patterns, factors 1 and 2 were significantly related with behavior problems of intellectually disabled children. Further, food preferences of the children were significantly related with adoptive behavior problems. The findings of this study clearly indicate that eating habits as well as food preferences are important factors in identifying adoptive behavior problems in intellectually disabled children. Based on the findings of this study, similarities and differences in eating habits are discussed, and implications for children are provided.
