Effects of the selective alpha-adrenoceptor agonists, clonidine, oxymetazoline and phenylephrine, on heart rate and contractile force were investigated in the isolated frog atria and it was attempted to examine the influence of adrenoceptor antagonist upon those. Clonidine produced dose-dependent negative chronotropic and positive inotropic effects. The negative chronotropic effect was significantly attenuated in the presence of prazosin and yohimbine but not propranolol. The positive inotropic effect was significantly attenuated by prazosin, yohimbine and propranolol. Oxymetazoline produced dose-dependent negative chronotropic and inotropic effects. The negative chronotropic effect was significantly attenuated in the presence of prazosin, which was partially augmented by yohimbine but was not affected by propranolol. The negative inotropic effect was not affected by propranolol but it was partially augmented by yohimbine and was partially attenuated by prazosin. Phenylephrine produced dose-dependent positive chronotropic and inotropic effects. The positive chronotropic and inotropic effect were significantly attenuated in the presence of propranolol but were not affected by prazosin and yohimbine. These results suggest that the negative chronotropic effect by clonidine and oxymetazoline is mediated by alpha-adrenoceptors, the positive chronotropic and inotropic effects by phenylephrine are mediated by beta-adrenoceptors, and alpha-adrenoceptors mediated the inhibitory chronotropic responses exists in the isolated frog atria.

This study investigates the effects of parental abuse and neglect on school life adjustment mediated by self-esteem in adolescents. Participants consisted of 2,259 middle school students from the Korean Children and Youth Panel Study 2012. Secondary questionnaire data on parental abuse and neglect, self-esteem, and school life adjustment are used for this study. Data were analyzed using descriptive analysis, Cronbach's a, Pearson's correlation analysis and multiple regression analysis. Baron and Kenny's method determined the mediation effect. SPSS ver 18.0 was adopted. The results were as follows. First, parental abuse and neglect were negatively correlated with the adolescent school life adjustment; however self-esteem was positively correlated with adolescent school life adjustment. Second, the results of the regression analysis revealed that adolescent school life adjustment was influenced both directly and indirectly; parental abuse had a direct effect on adolescents' school life adjustment and also had an indirect effect on mediated by self-esteem. Parental neglect had a direct effect on adolescent school life adjustment and had an indirect effect on adolescent school life adjustment mediated by self-esteem. The results indicated that self-esteem plays a crucial variable in the relationship of parental abuse and the school life adjustment. Also, self-esteem plays a crucial variable in the relationship between parental neglect and school life adjustment.

This study was conducted to explore the impact of the strategic supply chain orientation on the supply chain performance of raw materials export-import firms. In addition, this study analyzed the mediated effect of innovation and information sharing between the strategic supply chain orientation and supply chain performance of the firms. In the research model of this study considered the strategic supply chain orientation, innovation, information sharing and supply chain performance as the characteristics of the raw materials export-import firms by dividing the learning performance and market performance. The sample firms be analyzed were 445 firms. The 7 hypothesis including moderated effect were analyzed by using LISREL as structural equation modeling. According to the path analysis, the strategic supply chain orientation had a positive impact on the innovation activity. However, it did not have a positive influence on the information sharing. In the analysis of the mediated effect, the innovation activity of supply chain showed a full mediated effect between the strategic supply chain orientation and the information sharing. And the information sharing showed a partial mediated effect between the strategic supply chain orientation of these firms and the supply chain performance.

The purpose of this study is to investigate the relationship between work-family conflict and job-life satisfaction of married female workers. Two data sets were used in this study. Both data sets were gathered from structured questionnaires and time dairies. The first data set was collected from 370 married female production workers in 1995 and the second set was collected from 143 married female clerical workers in 1996. Job and life satisfaction were measured on 5-point Likert scale where 5= very unsatisfied and 5= very satisfied. The overact means for both groups were 2.97, 3.09 for job and life satisfaction respectively The findings of this study are; 1) Clerical workers have significantely higher job and life satisfaction than production workers. 2) Multivariate analysis reveal that work-family conflict is negatively related to job satisfaction while income is positively related to job satisfaction. 3) In the path analysis model, work-family conflict has a negative direct effect and indirect negative effect mediated through job satisfaction on life satisfaction. Job satisfaction and husband's division of housework have a positive direct effect on life satisfaction. However, total labor time has a negative indirect effect mediated through work-family conflict on life satisfaction and income huts a positive indirect effect mediated through job satisfaction on life satisfaction.

This study analyzed empirically the same data through SPSS statistic(regression analysis) and AMOS program(structural equation model) used for cause and effect analysis. The result of empirical analysis was as follows. The different outcome of coefficients and p-values were deducted. Especially, in the mediated effect testing, meanwhile, SPSS statistic(regression analysis) pictured mediated effect, AMOS program(structural equation model) did not picture mediated effect on the reject zone of null hypothesis(absolute t-value and C.R.-value were nearby 1.96). Eventually, this study showed that what program used determined the outcomes of coefficients and p-values(In particular, the outcomes were differentiated further in the increasing measurement error) though using the same data.

Copper inhibited PSII-mediated O2 evolution (H2OlongrightarrowDCIP, H2OlongrightarrowSiMo) but not PSImediated O2 uptake(DCIP. Asc.longrightarrowMV) in isolated Chinese cabbage chloroplasts. Copper toxicity on PSII-mediated O2 evolution was higher at alkaline condition than at acidic condition and was inhanced by light illumination after copper treatment. The increased toxicity by light illumination was not recovered by subsequent dark treatment. The inhibitory effect of copper on H2OlongrightarrowDCIP reaction was higher than that on H2OlongrightarrowSiMo reaction. This result suggests that there may be another inhibitory site of copper on PSII other than water oxidizing side of PSII.

Purpose - The TOEIC test has been leading the change in the quality and the globalization of companies for about last 30 years. The TOEIC test is taken by about two million people each year and is used as a criterion to select new employees in companies or government offices, for performance ratings, and for overseas posting selections. Universities also use TOEIC test in various ways. Since the TOEIC test is used for the selection of new students for admission, transferring extra credits, scholarships, graduation certification, and admission of international students studying abroad, many universities all over the country provide students with TOEIC study lectures through their own language institutes. Despite the fact, there has been no research on the service quality or even the current situation of these institutes. Thus, this study aims to evaluate the factors that impact TOEIC lecture service quality and analyzes the effect of the expectation related to the education service quality and the result of education on intentional behavior. Research design, data, methodology - Data was collected by administering a survey to current TOEIC students from different university language institutes. The survey questionnaire comprised of a five-point Likert scale. The demographic analysis was conducted using the frequency analysis method and the factor analysis was conducted to verify the validity of questionnaire over any variable. The reliability analysis was conducted to verify the reliability of the results. Besides, multiple regression analysis, regression analysis, and mediated effect verification were also conducted. For education service quality, four different independent variables such as reliability, response, conviction, and sympathy were considered using the SERVQUAL survey model. Based on the research models, the study hypotheses below were formulated in order to recognize an effect relationship between the variables. The four hypotheses are, "the hypothesis on education service quality and TOEIC study result expectation," "the hypothesis on education service quality and behavioral intention," "the hypothesis on study result expectation and behavioral intention," and "the hypothesis on study result expectation and mediated effect." Results - The results are as follows. First, the factors like response, conviction, and sympathy have a positive influence on TOEIC study result expectations. Second, the TOEIC study result expectation has a positive influence on the factors of behavioral intention such as re-sign up, positive word-of-mouth, "loyalty towards school." Third, it was verified that the mediated effect on behavioral intention was influenced by education service quality at university foreign language institute, while the study result expectation has only a partial mediated effect. Conclusions - The implications of this study are summarized as follows: First, it suggests a new research model for the effect of the expectation related to the education service quality and the result of education in the university language institutes on the behavioral intention. Second, it has established a relationship between the education service quality and study result expectation by verifying the mediated effect on them.
