Objectives: Radix Ginseng has been used for thousands of years to treat a wide variety of diseases. Radix ginseng has also been used as a traditional medicine for boosting Qi energy and tonifying the spleen and lungs. Traditionally, its effect could be obtained orally. Nowadays, a new method, the injection of herbal medicine, is being used. This study was performed to investigate the single-dose intravenous toxicity of water-soluble ginseng pharmacopuncture (WSGP) in Sprague-Dawley (SD) rats. Methods: All experiments were carried out at Biotoxtech, an institute authorized to perform non-clinical studies under the regulation of Good Laboratory Practice (GLP). At the age of six weeks, 40 SD rats, 20 male rats and 20 female rats, were allocated into one of 4 groups according to the dosages they would receive. The WSGP was prepared in the Korean Pharmacopuncture Institute under the regulation of Korea-Good Manufacturing Practice (K-GMP). Dosages of WSGP were 0.1, 0.5 and 1.0 mL/animal for the experimental groups, and normal saline was administered to the control group. The rat's general conditions and body weights, the results of their hematological and biochemistry tests, and their necropsy and histopathological findings were investigated to identify the toxicological effect of WSGP injected intravenously. The effect was examined for 14 days after the WSGP injection. This study was performed under the approval of the Institutional Animal Ethics Committee of Biotoxtech. Results: No deaths were found in this single-dose toxicity test on the intravenous injection of WSGP, and no significant changes in the rat's general conditions and body weights, the results on their hematological and biochemistry test, and their necropsy findings were observed during the test. The local area of the injection site showed minial change. The lethal dose was assumed to be over 1.0 mL/animal in both sexes. Conclusion: These results indicate that WSGP is safe at dosages up to 1 mL/animal.

본 논문에서는 현재 우리 사회에서 큰 이슈가 되고 있는 사교육비에 영향을 미치는 요인을 분석하였다. 사교육비가 논란이 되는 이유 가운데 하나는 각 가정에서 소비되는 전체 교육비 가운데 사교육비가 차지하는 비중이 높으면 경제적으로 교육에 대한 기회균등이 이루어지지 않는 문제를 유발할 수 있기 때문이다. 또한, 과도한 사교육으로 인해 기본적인 학교 교육보다 더 많은 시간과 비용을 할애한다면, 계층 간, 지역 간의 양극화와 더불어 학교의 기능이 저하되는 요인으로 작용할 수 있기 때문이다. 우리는 다양한 회귀분석 방법론과 분류분석 방법론을 이용하여 사교육비에 영향을 미치는 중요변수가 무엇인지를 파악하고 또 각각의 변수들이 어떻게 사교육비에 영향을 미치는 지를 분석하였다. 그 결과 대도시가 중소도시 보다 사교육비 지출이 높았고, 일반 고등학교, 중학교, 전문 고등학교, 초등학교 순으로 사교육비 지출이 높았다. 그리고 가구소득이 높을수록 사교육비 지출도 높았다.

The present was undertaken to establish a model for the control of adipocytes differentiation by using antibody from egg yolk. The emulsion of membrane protein of 3T3L-1 cell membrane protein with the complete Freund's adjuvant was firstly immunized in layer. Second and third boosting were undertaken with two weeks intervals by injection of the emulsion of the same antigen with the incomplete Freund's adjuvant. After 4 week of the first immunization, eggs were collected and antibody (IgY) was purified from egg yolk. The purity of IgY was 60-98% determined by single radial immunodiffusion (SRID) methods. Titer value of the antibody showed high reactiviy for the preadipocytes membrane protein measured by ELISA. When the IgY was added in the test media containing either 2.5% porcine serum or 10% FBS(control), the differentiation of 3T3L-1 cells and Glycerol-3-phosphate dehydrogenase(GPDH) activities was significantly decreased compared to the control cells(p〈0.05). When mice were subcutaneously injected with IgY raised against membrane protein of 3T3L-1 cells for 3 weeks, adipose tissue mass around ovary was tended to be decreased in female mice compared to those of control mice. It is suggested that a potential for manipulating of lipid accumulation through decrease in 3T3L-1 cell differentiation and fat accumulation in female mice by IgY treatment.

Objectives : The purpose of this study was to examine the influential factors for the choice of dental institutions among adult office workers who were one of major medical consumer groups, the relationship between their health promotion lifestyle and their choice of dental institutions, ways of boosting the efficiency of hospital management and differences in differentiation strategies among dental institutions. Methods : The subjects in this study were 160 office workers who were aged 20 and over and worked in Seoul, North Jeolla Province and South Jeolla Province. They were selected by convenience sampling, and a survey was conducted from February 1 to July 20, 2011. The answer sheets from 149 respondents were analyzed by the statistical package SPSS WIN 12.0 except for 11 incomplete ones. Results : As for the selection factors of dental institutions by general characteristics, they attached a statistically and significantly different importance to convenience according to gender(p<0.05), to reliability, facilities and cleanness according to age(p<0.05), to reliability and convenience according to academic credential(p<0.05) and to facilities and cleanness according to academic credential(p<0.01). Concerning the links between the form of using dental institutions and the selection factors of dental institutions, they gave a statistically and significantly different weight to reliability according to that(p<0.05). Convenience(p<0.001) was the primary selection factor of dental institutions among those who scored higher in health promotion lifestyle. Conclusions : Given the above-mentioned findings, it seemed that the regular implementation of oral health plans geared toward workers and the development of educational programs are required to promote the oral health of workers. But this study examined the workers in several regions only, and the findings might not be generalizable.
