Brain cells produce cytokines and chemokines during the inflammatory process of many neuronal diseases both in animal models and in patients. Inflammatory cytokines are the main responsible for the onset of inflammatory cascade. During the past decade, a growing corpus of evidence has indicated an important role of these cytokines in the development of brain damage. ZhenganXifeng-tang (ZGXFT) is a Korean herbal prescription, which has been successfully applied for the treatment of various neuronal diseases. However, its effect in experimental models remains unknown. Astrocytes are predominant neuroglial cells of the central nervous system and are actively involved in cytokine-mediated events in inflammatory disease. An inflammatory response associated with β-amyloid (Aβ) and interleukin (IL)-1β is responsible for the pathology of inflammation disease. To investigate the biological effect of ZGXFT, the author examined cytotoxicity, effect of cytokines (IL-6 and IL-8) secretion and expression of cyclooxygenase-2 (COX-2) on human astrocytoma cell line U373MG stimulated with IL-1β plus M fragment 25-35 (Aβ [25-35]). ZGXFT by itself had no effect on cell viability on human astrocytoma cells. The secretion of IL-6 and IL-8 was inhibited by pre-treatment with ZGXFT in human astrocytoma cells. In addition, the expression of COX-2 was induced by IL-1β plus AB[25-35] and was partially inhibited by treatment with ZGXFT. The author demonstrates the regulatory effects of inflammatory reactions by ZGXFT in human astrocytes for the first time and suggest the anti-inflammatory effect of ZGXFT may reduce and delay pathologic events of inflammatory disease.

the purpose of this study is to investigate the effect of household type on human capital enhancement expenditures and to compare the difference in these expenditures between female-hemale-headed and married-couple households. Data for this study were from the 1990-91 Consumer Expenditure Survey(CES) and consisted of a sample of 7,225 married-couple and 1,391 female-headed households with children under age 18. The dependent variable to measure human capital expenditures was the sum of four sub-components-education reading leisure and health care expenditures. Tobit analysis with a dummy variable for household type was used to identify the effect of household type on the dollars spent on human capital expenditures. The effect of household type was significant in human capital expenditures indicating that female-headed households spent significantly less for this category than did married-couple household holding other factors constant. the findings of this study suggested that income from a public assistance program was associated with lesser expenditures on human capital while social security income source was associated with greater human capital expenditures, It was also found that the addition of family members between ages of 6 and 17 positively affected human capital expenditures. Understanding these factors is useful for family resource management professionals who work with female-headed households.

In order to examine oxidative stress of reactive oxygen species and the antioxidant effect of Citri Reticulatae Pericarpium (CRP) extract, human skin melanoma cells were treated with various concentrations of hydrogen peroxide ($H_2O_2$). Antioxidant effect of CRP extract on $H_2O_2$-induced cytotoxicity, cell viability, DPPH-radical scavenging activity and superoxide dismutase (SOD)-like activity. In this study, $H_2O_2$ decreased cell viability of cultured human skin melanoma cells in dose- and time-dependent manners, and then, midcytotoxicity value (MCV) was determined at $60\;{\mu}M$ after human skin melanoma cells were cultured for 5 hours in the media containing $20{\sim}60\;{\mu}M$ of $H_2O_2$, respectively. The $H_2O_2$ was on cultured human skin melanoma cells because MCV of $H_2O_2$ was lower than $100\;{\mu}M$. In the antioxidant effect of CRP extract, CRP extract increased cell viability DPPH-radical scavenging activity and SOD-like activity. From these results, it is suggested that $H_2O_2$ was very toxic on cultured human skin melanoma cells. And also, CRP extract has the antioxidant effect on $H_2O_2$-induced cytotoxicity.

In vitro anticancer effect of Chinese cabbage kimchi fractions was investigated by using human cancer cells, AGS human gastric adenocarcinoma cells and HT 29 human colon adenocarcinoma cells. The Chinese cabbage kimchi(fermented for 4 days at 15oC) was fractionated into 7 groups, methanol extract, hexane fraction(fr.), methanol soluble fr., dichloromethane fr., ethylacetate fr., butanol fr. and aqueous fr.. Chinese cabbage kimchi fractions inhibited the growth of AGS and HT 29 cancer cells as dose dependent. In particular, the dichloromethane fr. showed the highest inhibitory effect among other fractions. When the dichloromethane fr.(0.2mg/ml) was treated, the number of AGS and HT 29 survival cancer cells reduced to 12$\times$104/ml and 11$\times$104/ml compared to 166$\times$104/ml and 50$\times$104/ml of the controls, respectively. Chinese cabbage kimchi fractions also inhibited the DNA synthesis of the cancer cells. They inhibited the DNA synthesis of AGS human gastric adenocarcinoma cells more efficiently than that of HT 29 human colon adenocarcinoma cells. These results indicate that Chinese cabbage kimchi fractions show in vitro anticancer activity and the dichloromethane fr. among them reveals the highest effect.

IIn this paper, I investigate the effect of special education teachers' self-leadership on job-satisfaction. The data was collected from 141 special education teachers to analyze the correlations between self-leadership, job and life satisfaction. In addition, another purpose is to analyze how self-leadership influence on job satisfaction (human relationship, assigned tasks) and life satisfaction. The results are shown as follows. First, self-expectation and goal setting, self-expectation and human relationship, human relationship and assigned tasks have meaningful correlation. Second, self-expectation and self-rewarding are sub-factors of self-leadership that have great influence on human relationship which is a subordinate factor of job satisfaction and assigned tasks. Third, self-expectation and self-rewarding are factors of self-leadership that have a great influence on life satisfaction. Finally, it shows that self-leadership has an effect on life satisfaction through assigned task, which is a factor of job satisfaction. However, through human relationship, self-leadership does not have a meaningful effect on life satisfaction. This study is significant by finding sub-factors which influence special education teacher's self leadership, job satisfaction and life satisfaction by using Bootstrap method.
