This paper describes a case study on an enterprise ontology(30) based analysis and representation of the production operation in shipbuilding. The production operation consists of steel fabrication, assembly, election, launching, sea trial and delivery process. We represent and analyze the steel fabrication process and the piping design business of the assembly process among them. First, we build an ontology on concepts of steel fabrication process and the piping design business of assembly process. And then we merge it with the original EO. We represent each process and analyze current state of production process with the merged EO and $Prot{\acute{e}}g{\acute{e}}$ plug-ins. Moreover, we can analyze dependency relations among the workflow elements. Through the case study, we have found the effectiveness of EO in business management and process management in complex heavy industries.

The machinery industry provides infrastructure to many manufacturing industries and it has strong influences on performance and quality of products. However, Korean economic growth has been constantly causing the korean general machinery industry to significantly depend on Japan. To solve this problem, many industrial policies have been tried. In this paper, we divide the value chain of general machinery industry into four steps; technology development step, manufacturing step, marketing step, and after-sales management step. We study the relationships between each of these steps and the awareness of dependency on Japan. For empirical analysis we surveyed 207 domestic companies in general machinery industry. The findings are that the three factors, technology development competency, marketing competency and after-sales management competency have significant relationships with dependence on Japan. Manufacturing competency is not a significant factor. As control variables, the type of manufacturers has effect on dependency on Japan. The company size, the kinds of products and technology levels of products don't have effects on the relationship between the four steps of the value chain and dependency on Japan. To overcome the trade imbalance with Japan in the general machinery industry, we recommend to develop technology development competency, marketing competency, and after-sale management competency. Also we need to adopt industry supporting policies, not depending on all three control variables of company sizes, the kinds of products and the technology levels of products, but depending on the type of manufacturers.

This paper analyzed the implementation process of experts managing the case of grandparent and grandchildren families in the case management process, as the useful approach to strengthen the function of grandparent and grandchildren family. The methodology were the analysis on 6 management cases by step and the analysis on the interview with 3 experts implementing the case management on grandparent and grandchildren families. As a result, major complaints from grandparent and grandchildren families were basic livelihood and economy area, physical and mental health area, child care and education area and culture area. The service goals were set by such classification and support service was provided using the internal and external resources. The case management process was effective for improving the satisfaction on life by positively changing the grandchildren and promoting the psychological and emotional stability. 6 cases were under the post management after the analysis was completed and linked to the program 'Reinforcement of Family Ability of Grandparent and Grandchildren Family.' In accordance with the interview with the experts in case management, the grandparent and grandchildren family case management was characterized by high dependency and difficulty in expressing the desires. They required the long-term approach as well as the approach to restore the relationship with the original family.

This study investigates how bioecological variables affect the child's multiple intelligence through independent and interactional ways. The subjects of this study were 147 pairs of 5-year-old children and their mothers, and the Project Spectrum was employed to measure multiple intelligences. Each mothers was asked to answer a questionnaire on her child's temperament, her maternal parenting style, 'goodness of fit' and 'the fit of child's intelligence'. Data were analyzed using a factor analysis and a hierarchical multiple regression with SPSS WIN 15.0. The main findings were as followings; First, 'the goodness of fit' to the child's temperament moderated the effect of a maternal parenting style that would foster child's dependency on the mathematical intelligence through interaction. 'The fit of child's intelligence' also moderated the effect of maternal positive parenting style to the child's mathematical intelligence. Second, in language intelligence, girls were more verbally intelligent than boys. In that regard, because the sex variable entails a combination of both inherent attribute and social-cultural effects, that result can be interpreted as an interaction between the individual and the environment. Lastly, a maternal parenting style that would foster child's dependency moderated the effect of the child's regular temperament on interpersonal intelligence. This means that the child's regular temperament can be a protective factor for the negative effect of a maternal parenting style that would foster child's dependency This study suggests that interactional factors such as 'goodness of fit' should be considered in studies involving children.

Following the global trend of the delayed transition to adulthood, the number of unmarried middle aged adult children living with, or economically dependent on their parents has increased in Korea. Middle aged adult children in Korea are traditionally expected to satisfy their duty to support their elderly parents both in economic and emotional needs. This study aims to explore group differences in unmarried adult children in their mid 30s or older and in parents having unmarried middle aged child(ren) depending on co-residency and the children's eonomic dependency in Korea. Using quota sampling in terms of living arrangements (living together vs. living apart), 500 unmarried adult children 35 years of age or older and 500 elderly parents, having at least one unmarried child in the mid of 30s or over, were selected in Seoul, Korea in June 2016. First, the findings show that unmarried adult children living together with their parents and depending on their parents economically were in the lowest level of educational achievement and the lowest level of monthly average income among the respondents. Second, both unmarried adult children and parents from the group of co-residency and economically dependent showed the lowest level of psychological well-being. Third, parents from the group of co-residency and economically independent had mostly positive relationships with children, whereas, parents from the group of living apart and economically dependent reported the most negative relationships. Finally, respondents included in the group of co-residency had positive attitudes toward marriage and the support for their elderly parents regardless of the child's economic dependency. This study has implications for the increasing number of unmarried middle aged adult children and their elderly parents.

The myth about BPO is: since firms do not want to continue to control the business process, they outsourced it to the external provider. Therefore, there is no need for controlling the outsourced process. Based on resource dependency theory, this study explores control mechanism used in BPO context. The overall approach of this study is qualitative, inductive and exploratory. First, a generic framework on the control structure is derived from extant literature, which includes outcome/process control, IS and social control. This framework is applied to a Korean BPO case. This study has found that the hybrid control structure consisting of behavior, outcome and social control mechanisms are effective for BPO success. As outsourcing grows rapidly and IS functions become smaller, the business struggles to redefine its IS capability. This research proposes setting up proper control mechanism between user and BPO service provider as new IS capability that business should focus on; and provides guidelines for managers in development of new IS capability.

This study identifies the factors that influence juvenile delinquency, which has increased both offline and online. It is hypothesized that the influence of negative parenting on online and offline juvenile delinquency is mediated through smartphone dependency and personal emotional problems. In addition, the study hypothesizes that participation in cultural activities soothes the influence. Using SPSS 22.0 and AMOS 20.0 programs, we conducted a confirmatory factor analysis, a multi-mediation analysis, and a cross-group comparative analysis. The analyses found the significant mediation effect of smart phone dependence and personal emotional problems on the relationship between negative parenting and juvenile delinquiency. Participation in cultural activities overall weakens the hypothesized effects.

According to recent empirical studies, there is a systematic pattern in temporal behaviors of asset returns, and that systematic pattern is related to the business cycle. I propose a model which captures this evidence. This is done by considering a state dependent preference structure where state dependency is related to the business cycle. In this setting, the three main puzzles(i.e., the volatility puzzle, the equity premium puzzle, mean reversion) are understood as interrelated behaviors.
