  • The purpose of this study is to examine the Korean social workers' level of social work values, advocacy attitude and advocacy intervention, and to verify the relations among social work education, social work advocacy and social work values by examining whether social work education influences social work advocacy and social work values, and whether social work values affect social work advocacy. Further, this study wishes to confirm not only the direct effect that social work education has on social work advocacy, but also how social work education indirectly influences social work advocacy through social work values on the social level as a mediator. The research of this study was conducted on 461 social work practitioners who have obtained either social worker licenses or mental health social worker licenses and are currently working in the field. As survey tools, this study utilized social work advocacy attitude, social work advocacy intervention, outcomes of social work education, social work values, self-esteem and locus of control. Collected data were analyzed by using SPSS/PC+ 11.5 for one-way ANOVA and t-test, Pearson's correlation, reliability analysis, exploratory factor analysis and multiple regression. To sum up the results of the study in terms of the research hypothesis, the research hypothesis was established according to the analysis method of the testing mediation of Baron & Kenny (1986) in order to examine whether social work values on the social level intervene between social work education and social work advocacy. The results of the hypothesis test confirm that social work values on the social level serve as a mediator variable.

  • The purpose of this study is to test the economic rationality hypothesis of the low fertility trap among 412 college students at 13 private universities located in Seoul. The respondents were requested to complete the self-administered questionnaire, and the hierarchical multiple regression analyses were performed for analyzing the data. The major findings of this study were as follows: First, the students' views on the prospects for their future employability were 54.6% for big business, 64.51% for medium-sized business, and 49.63% for public sector. In the most employable job, the mean desired monthly salary was 3,505,400 won, while the mean expected monthly salary 2,753,600 won. Second, hierarchical regression analyses revealed that the family income in parental home was positively related to youths' consumption aspirations. Finally, the gap between youths' consumption aspirations and their expected income was negatively related to their desired number of children, while not significantly related to their planned age of first child birth. Thus, the low fertility trap hypothesis was supported in terms of birth rate drop, but not supported in terms of childbearing postponement. The implications of the study results are discussed.

  • This study examined the relationship between determinant factors of FDI and management performance, and tested moderating effects by competitive strategy. Questionnaires were gathered from 113 respondents, but only 92 valid copies were analyzed through SPSS WIN 18.0. The major empirical results are as follows: In hypothesis 1, Firm-Special Advantage impacted on Management Performance strongly, Internal Advantage impacted on Management Performance strongly, and Locational Advantage impacted on Management Performance strongly. In Hypothesis 2, the moderating effects by competitive strategy on the relationship between determinant factors of FDI and management performance were tested through multiple regression. The result of the moderating effects by competitive strategy were found to be insignificant. Implications of the finding as well as the limitations of this study are also discussed.

  • Allergic disorders such as atopic dermatitis and asthma are common hyper-immune disorders in industrialized countries. Along with genetic association, environmental factors and gut microbiota have been suggested as major triggering factors for the development of atopic dermatitis. Numerous studies support the association of hygiene hypothesis in allergic immune disorders that a lack of early childhood exposure to diverse microorganism increases susceptibility to allergic diseases. Among the symbiotic microorganisms (e.g. gut flora or probiotics), probiotics confer health benefits through multiple action mechanisms including modification of immune response in gut associated lymphoid tissue (GALT). Although many human clinical trials and mouse studies demonstrated the beneficial effects of probiotics in diverse immune disorders, this effect is strain specific and needs to apply specific probiotics for specific allergic diseases. Herein, we briefly review the diverse functions and regulation mechanisms of probiotics in diverse disorders.

  • This study was designed to identify the information sources of reference used by male college students. Theoretical framework is based upon social comparison theory, reference group theory, and Kotler's model of personal and non-personal sources of reference. The subjects were 287 male college students. The questionnaire were distributed to the school area and the commercial area such as Shinchon, Myung-Dong, and Apkujung-Dong in Seoul. Means, standard deviation, frequency, T-test, one-way ANOVA, and Duncan's multiple range test were applied for the analyses of data. The result of hyporthesis 1 showed that male college student utilize personal and non-personal sources of reference indiscriminately. The result of hypothesis 2 showed that male college students consult the socially high-proximal group such as a girl friend(a lover) and mother most actively. The result of hypothesis 3 found that male college students use position media most actively, especially in-store displays, followed by print media and broadcast media.

  • Korean property and liability insurance companies have underwrited hull insurance without proper undrewriting ability. But after April 1996. in case of Korean insurance market being opened the companies have to make hull insurance rate by themselves. Accordingly, in this study, the writer embodies important factors in making hull insurance rate by an empirical survey. In empirical survey, the writer used a questionnaire, 74 proper data was obtained from 96 officers working in making hull insurance rate in 12 Korean property and liablity insurance companies and 24 the foreign companies at home. Reliability was tested by Cronbach's Alpha and a conceptual validity by Factor Analysis. Hypothesis estabilished in this study was tested by Correlation and Multiple Regression Analysis. Results of testing hypothesis are as follows: Firstly, the traits of insurer and the assured influence significantly(P<0.05) on making hull insurance rate. Secondly, expected loss ratio, ship manager, ship's age, insured amount, level of the cost of repairing and salvage, shipowner, period of insurance, level of overseas rating, profit and expense, trading limits, ship's classification, conditions of insurance, and ship's size influence significantly(P<0.05) on making hull insurance rate.

  • In many studies, a researcher attempts to describe a population where units are measured for multiple outcomes, or responses. In this paper, we present an efficient procedure based on ranked set sampling to estimate and perform hypothesis testing on a multivariate mean. The method is based on ranking on an auxiliary covariate, which is assumed to be correlated with the multivariate response, in order to improve the efficiency of the estimation. We showed that the proposed estimators developed under this sampling scheme are unbiased, have smaller variance in the multivariate sense, and are asymptotically Gaussian. We also demonstrated that the efficiency of multivariate regression estimator can be improved by using Ranked set sampling. A bootstrap routine is developed in the statistical software R to perform inference when the sample size is small. We use a simulation study to investigate the performance of the method under known conditions and apply the method to the biomarker data collected in China Health and Nutrition Survey (CHNS 2009) data.

  • This study examines that pricing multiple on and incremental explanatory power of equity book value(earnings) increase(decrease) as financial health decrease. Test using a sample of 75 bankrupt firms and test using a cross-sectional, pooled sample both yield inference consistent with predictions. It is thus hypothesized that the more bankrupt time we, the higher(lower) pricing multiple book value of equity(earnings) obtained. Findings are robust to inclusion of for debt/assets ratio, ROA, and ROIC. Overall, the results is the hypothesis.

  • This paper addresses the issue of constraints on the conversion of the participle II in German, proposing a constraint-based lexical semantic approach. I argue against the widely accepted syntactic view which is based on the dichotomous distinction of intransitive verbs, which has been advanced by the Unaccusative Hypothesis [Perlmutter (1978)]. Several arguments are also given against the semantic view which is based on some aspectual notions such as 'telicity', 'transformativity' or 'terminativity'. The crucial constraints on the conversion of the participle II in German, it is argued, is instead two lexical semantic entailments, movement with a definite change of location and affectedness. These and other lexical semantic entailments in the sense of Dowty (1991) are encoded into the multiple inheritance type hierarchy of qfpsoa. The proposal made in this paper is based on the multiple inheritance hierarchy which is envisaged in a recent framework of head-driven Phrase Structure Grammar.
