The biggest exchange of international environment of shipping logistics in 21 century should appear ultra-mega container ships on the shipping market. The competitive trend of large size container ship was based on economics of scale among the international shipping business. In the environment, shipping firms consider the integration of freight forwarder and shipper in the international logistics process. The aims of this research analyse a relation between the environment uncertainty and logistics information system(LIS) and the integration and resolve the integration and its impact on logistics performance. The research methodology of this research analyse structural equation modeling on the relation of variables. The results of research are as follows. First, Environmental uncertainty significantly influences the internal integration and the external integration. Second, LIS has an influence on the logistics integration by providing the foundation for LIS utilization in international logistics process. Third, the internal integration significantly influences a logistics performance, which implies that firms should promote interaction and collaboration through internal process integration to achieve logistics performance as the logistical cost and service. But the external integration is not significantly a logistics performance.

Purpose: This study was conducted in order to define factors influencing learned helplessness in undergraduates. Independent variables including external entrapment, internal entrapment, social support, trait anger, state anger, and anger expression were used to predict learned helplessness. Methods: Data were analyzed using the SPSS/WIN 20.0 program for descriptive statistics, Pearson correlation coefficients and stepwise multiple regression. A total of 241 undergraduates recruited from September to November 2012 were included in the study. Results: Four factors of learned helplessness were founded to show significant correlation with external entrapment, internal entrapment, social support, trait anger, state anger and anger expression. Stepwise multiple regression analysis showed that 64% of the variance in learned helplessness was significantly accounted for by internal entrapment, social support and anger expression. Conclusion: This study showed that perceived entrapment and social support are important predictors of learned helplessness. Therefore, in order to reduce learned helplessness in undergraduates, it is necessary to design an intervention program with strategies to help in coping with and reducing perceived entrapments.

The objectives of this research paper are to identify the types of the firm's new product development strategy and their characteristics about business strategy, to examine the effect of each type on new product outcomes, and to explore the contingency variable influencing the relationship between these types and new product outcomes. The result of the research are summarized as follows : First, in terms of both the resource allocation for product innovativeness and technology acquisition method, this study suggests 9 types of the firm's new product development strategies- Type 1 (pursuing low innovative products/relying on external technology), Type 2 (pursuing low innovative products oriented/relying on internal technology), Type 3 (pursuing low innovative products/relying on mixed technology), Type 4 (pursuing high innovative products/relying on internal technology), Type 6(pursuing high innovative products /relying on mixed technology), Type 7 (balancing low and high innovative products/relying on external technology), Type 8 (balancing low and high innovative products/relying on internal technology), Type 9 (balancing low and high innovative products/relying on mixed technology). Second, these 9 types are deeply associated with the firm's business strategic variables such as product differentiation and market differentiation, and exhibit different level of both technical and commercial performance of new products. Finally, the effects of these types on new product outcomes are different according to industrial environment and firms' characteristics with respect to size and technological capability.

Purpose: The purpose of this study was to identify the factors influencing health risk behavior in high school students. Methods: The subjects were 512 students from 4 high schools in 3 cities. The questionnaire measured the level of self-esteem, self-efficacy, internal locus of control and health risk behaviors. The data were analyzed using descriptive statistics, t-test, ANOVA, Scheffe test, Pearson's correlation coefficient and stepwise multiple regression analysis. Results: There were significant differences in the health risk behaviors according to sex, a classification of the school, whether or not smoking of mother, whether or not live alone, level of harmonious family, level of satisfying school-life and three variables of them were significant differences by Scheffe test. There was a significant positive correlation between sub-dimension of health risk behaviors and the self-efficacy, self-esteem, internal locus of control were negative correlation with health risk behaviors. The most important influential factor of the health risk behaviors was the self-efficacy. Conclusion: From the studies reviewed, improving the self-efficacy, self-esteem, internal locus of control and the general social environment of students will probably be the most effective strategies for primary prevention of health risk behaviors.

this study examined the correlates of adult attachment focused on internal working models of 201 housewives. Findings indicated that 68.3% of subjects were classified as secure whereas 27.5% as avoidant and 4.2% as anxious. Greater security was associated with slightly less avoidance while greater anxiousness was associated with slightly greater avoidance. That is subjects who possessed more security tended to be less avoidant while subjects who possessed more anxiousness tended to be more avoidant. The primary characteristics classifying subjects into those three attachment styles were feelings about closeness dependence and anxiousness in relationships with others. Adult attachment was related in theoretically expected ways to one's history of attachment and parenting. Secure subjects were more likely to report warm/responsive parental caregiving style than insecure styles. Insecure subjects in comparison with secure subjects perceived their mothers as cold inconsistent and ot very responsive. Anxious subjects dscribed their fathers as cold and rejecting. The secure attachment style in comparsion with insecure styles was associated with positive mental models of self and social world indicating greater self-esteem positive beliefs about self and others positive relationships with their children greater marital satisfaction and greater secure attachment to their husbands. These results suggest that internal working model offers a useful perspective on adult attachment.

Due to a rapid change of business environment, many firms are eager to find the competitiveness by information technology adoption and diffusion. In this exploratory study, we examined the applicability of a previously proposed model to evaluate IT competitiveness based on the innovativeness and verified it's propriety with empirical data. As suggested by previous studies, the proposed model considers a variety of corporate and market characteristics concerned with IT adoption, and it consists of several internal and external impacting factors, which have influence on technology diffusion and its performance. For the empirical analysis, the survey data of domestic ERP adoption cases were adopted from 128 small and medium-sized enterprises(: SMEs) in IT and electrical engineering industry, and analyzed by partial least squares(: PLS) - a popular structural modeling and multivariate projection technique to latent variables. The results indicated positive supports for the research model of external and internal IT adoption factors' influences on innovativeness' performances. However, there are a couple of limitations not to show the reliability of selected measurement items and the generality of model proposed in this exploratory study.

This paper presents plastic limit loads and approximate J estimates for axial through-wall cracked pipe bends under internal pressure and in-plane bending. Geometric variables associated with a crack and pipe bend are systematically varied, and three possible crack locations (intrados, extrados and crown) in pipe bends are considered. Based on small strain finite element limit analyses using elastic-perfectly plastic materials, effect of bend and crack geometries on plastic limit loads for axial through-wall cracked pipe bends under internal pressure and in-plane bending are quantified, and closed-form limit solutions are given. Based on proposed limit load solutions, a J estimation scheme for axial through-wall cracked pipe bends under internal pressure and in-plane bending is proposed based on reference stress approach.
