  • The purpose of this study was to identify imported apparel selection behavior according to Mongol women's conspicuous consumption orientation. A self-administered questionnaire was used for data collection. First, factors of conspicuous consumption orientation were high price and luxury brand, fashion style, altruism, prestige, and brand. Mongol women were segmented into the price and prestige pursuit group, the fashion and brand pursuit group, the altruism pursuit group, and the conspicuous consumption retard group. Second, factors of motivating the selection of imported apparel were value, symbolism, and aesthetics, and Mongol women considered the aesthetics of imported apparel important. Married Mongol women in their 30's chose imported apparel because of its symbolism. More married women selected imported apparel because of its value and more educated women selected imported apparel because of its aesthetics. Women with higher apparel expenditure selected imported apparel because of its value and symbolism. Quality, diversity, and the fit of imported apparel were the selection criteria for Mongol women and they were satisfied with the quality, diversity, and fit of the imported apparel. Brand awareness was very important when selecting imported apparel but the women's satisfaction level was significantly low. Third, more women in their 30's, unmarried, or with a lower educational level were found in the price and the prestige pursuit group, and the price and prestige pursuit group and the altruism pursuit group selected imported apparel for its aesthetics. More unmarried women in their 30's with a higher educational level were found in the fashion and brand pursuit group and selected imported apparel for its value, symbolism, and aesthetics. More unmarried women in their 20's with a higher educational level were found in the altruism pursuit group, but unmarried women in their 20's with a lower educational level were found in the conspicuous consumption retard group.

  • 본 논문에서는 가솔린 기관에서 흡입 밸브 각도가 엔진의 부분부하 성능에 어떠한 영향을 미치는지를 혼합비 반응 특성을 통해 알아보았다. 흡입 밸브각이 작은 엔진이 흡입 밸브 각이 큰 엔진에 비해 배기가스 중 질소산화물 (BSNOx)의 양은 줄어들었고, 점화시기는 지각되었고, 제동연료소비율은 조금 개선되었다. 배기가스 중 질소산화물의 양이 줄고 점화시기가 지각 되었다는 것은 급속 연소가 일어났다고 판단할 수 있다. 시험 결과를 살펴보면 흡입 밸브각이 작아지면 기관의 연소 성능이 좋아지는 것으로 판단 될 수 있다.

  • 유지류는 산화에 의해 품질이 저하되며 이를 방지하기 위해 항산화제를 첨가하는 방법이 널리 이용되어 왔다. 그러나 현재까지 많이 이용되어온 tocopherol과 BHA는 상온에서는 높은 항산화 효과가 있지만 튀김 식품과 같이 18$0^{\circ}C$이사의 고온처리가 필요한 경우에는 열안정성이 매우 낮아 이들 항상화제들의 대부분 분해되거나 산화방지 능력을 상실한다. 식물체에서 안정한 자류 라디칼을 형성할 수 있는 구조를 갖는 스테롤, 즉 곁사슬에 에틸리덴기를 갖는 citrostadienol, $\Delta$5-avenasterol과 fucosterol이 고온에서 안정한 항산화 효과가 있다고 보고되었으며 그 중에서 $\Delta$5-avenasterol 이 고온에서 가장 높은 항산화 효과가 있다고 한다. 다라서 식품의 기호성과 저장성을 높이기 위하여 고온에서 안정성을 갖는 천연 항산화제의 개발이 필요하므로 문헌 고찰을 하여 정리하였다.

  • KH-BaRoKer-SeongJangTang (KBS) is a recently developed formulation by using traditional drugs considering traditional medical theory of Oriental books such as ShinNongBonChoGyeong and JuRye, which has been used to improve the growth of child in Korea. Although KBS is usually prescribed to many children who are in retard for their age, its pharmacological effects have not been fully understood in experimental models. The aim of this study was to evaluate the effects of KBS on bone growth. Growth plate thickness and bone parameters such as bone volume/tissue volume (BV/TV), trabecular thickness (Tb.Th), trabecular number (Tb.N), connection density (Conn.D), and total porosity were analyzed by means of microcomputed tomography. Serum insulin-like growth factor-I (IGF-I) levels were measured by enzyme-linked immunosorbent assay. Hepatic IGF-I mRNA expression was analyzed by real-time polymerase chain reaction. Phosphorylation of signal transducer and activator of transcription5 (STAT5) was investigated using Western blot analysis and immunohistochemistry. The thickness of growth plate was increased by KBS. BV/TV, Tb.Th, TbN, Conn.D, and total porosity were improved by KBS. Hepatic IGF-I mRNA and serum IGF-I levels were elevated by KBS. Phosphorylation of STAT5 was increased with administration of KBS. These results suggest that KBS would be helpful to children who are in retard for their age through the elevation of IGF-I.

  • According to the recent rapidly increasing that construction works are gradually Manhattanized mainly the grand scaled residential buildings, the foundation of the building that is related to safety is increasing for building as a grand scaled mat concrete. Because mat concrete can not be simultaneously placing of concrete in a great quantity due to the circumstance at the field, the inequal deformation of the tensile stress that according to the time lag of hydration heat between the upper layer and the lower layer is affecting as a cause that is the possibility of crack occurrence by increasing. Accordingly, this research checked the efficiency of super retard concrete in applying real structures, and we implemented the preparatory experiment to settle up the inequal deformation of the tensile stress substantially that is according to the time lag of placement between the upper layer and the lower layer by controlling the setting time using the super retarding agent. As the result of test, the more target of delay time lengthened, the more fluidity increased and air content indicated a little differences. There was from 2 to 10 hours between the standard curing and the outside curing at the setting time and in case of calculating the rate of mixing at real structure is required that mix promotion, increasing the amount of mixing, by setting up the curing temperature. The super retard concrete showed the result that in compressive strength, early-age strength was smaller than normal concrete whereas it was same or more figures from at the aging 28days because of the super retarding agent.

  • The purposes of this study were to identify point makeup purchasing and using behavior according to the personal color awareness. Most women considered their favorite color first when purchasing lipsticks and skin color when purchasing cheek powder or foundation. They considered makeup concept first when applying lipsticks, eye shadows, and cheek powder but skin color applying foundations and manicures. Factors of personal color awareness were preferences & utilization awareness, other's advice, and direct awareness, and were segmented into PC intermediate group, high PC group, and PC retard group. PC intermediate group were in the late 20's and the early 30's, average incomes with high education, and patronized discount stores for point makeups, used fashion color as a criterion when selecting lipsticks, foundations, and manicures, apparel color when applying eye shadows, skin color when applying cheek creams, and preferred imported lipsticks and manicures. High PC group were among unmarried women in the early 20's, university students, high income households with medium level of pocket money, spent more for point makeup, and patronized department stores and internet shopping mall, used skin color or fashion color as criteria when selecting point makeup, referenced makeup concept when applying point makeup, preferred imported point makeup. PC retard group were among married women in the late 30's with low education and low income, spent less for point makeup and pocket money, and selected domestic point makeup, used their favorite color as a criterion when selecting point makeups and apparel color when applying lipsticks and cheek creams.

  • Ibuprofen-loaded gelatin microcapsule, a solid form of microcapsules simultaneously containing ethanol and ibuprofen in water-soluble gelatin shell was previously reported to improve the dissolution of drug. In this study, to retard the initial high dissolution of ibuprofen from gelatin microcapsule, the ibuprofen-loaded cross-linked gelatin microcapsule was prepared by treating an ibuprofen-loaded gelatin microcapsule with glutaraldehyde and its dissolution was evaluated compared to ibuprofen powder and gelatin microcapsule. The ibuprofen-loaded crosslinked microcapsule treated with glutaraldehyde for 10 and 60 sec gave significantly higher dissolution rates than did ibuprofen powder. Furthermore, the dissolution rate of ibuprofen from the cross-linked microcapsule treated for 10 sec was similar to that from gelatin microcapsule. However, the dissolution rate of ibuprofen from the cross-linked microcapsule treated for 60 sec decreased significantly compared to gelatin microcapsule, suggesting that the treatment of gelatin microcapsule with glutaraldehyde for 60 sec could cross-link the gelatin microcapsule. Furthermore, the cross-linking of gelatin microcapsule markedly retarded the release rate of ibuprofen in pH 1.2 simulated gastric fluid compared to gelatin microcapsule. However, the cross-linking of gelatin microcapsule with glutaraldehyde hardly changed the size of gelatin microcapsules, ethanol and ibuprofen contents encapsulated in gelatin microcapsule. Thus, the ibuprofen-loaded cross-linked gelatin microcapsule could retard the initial high dissolution of poorly water-soluble ibuprofen.
