A reliability-based cost-benefit model for the risk management of oil platforms in the formulation of optimal decisions based on life-cycle consideration is proposed. The model is based on structural risk assessments and the integration of social issues and economics into the management decision process. Structural risks result from the platform's exposure to the random environmental loading associated with the offshore site where it is located. Several alternative designs of a typical platform are proposed and assessed from the cost-effectiveness viewpoint. This assessment is performed through the generation of cost/benefit relationships that are used, later on, to select the optimal design.

This study investigated the structural relationships among performance expectancy, effort expectancy, social influence, facilitating condition, attitude, usage intention and actual use. In order to examine structural relationships among variables, we surveyed 285 high school students in spring semester of 2014. After collecting data, we examined causal relationships among variables using structural equation modeling. The results of this study were as follows: First, performance expectancy and effort expectancy significantly affected attitude; however, social influence did not. Second, attitude affected usage intention and usage intention significantly affected actual use. Third, the indirect effect of attitude between performance expectancy, effort expectancy and usage intention were significant and the indirect effect of usage intention between attitude and actual was also significant. Finally, the moderating effect of gender and experience were not significant. Based on this study, the practical strategies to facilitate usage intention and actual use of mobile learning of high school students were suggested.

Purpose: This study analyzes the characteristics of the Quality Management performed by SMEs in the Defense Industry in supply chains and analyzes the effect of the continuous improvement activities based on cooperation. Especially, for Military Supplies, the suitability of products is usually decided by judging their conformity to the specification, and from this structural characteristic, this study would analyze the structural relationship of systematic improvement activities with Supply Chain Quality Management(SCQM) and Business Performance(BP). Methods: Continuous improvement activities(CI) have significance as the driver force for the promotion of Quality Management. Thus, this study analyzed the causal relationships from the perspective of the process among CI, SCQM and BP. For an analysis of the structural characteristics and causal relationships among the constituents, AMOS was used, and 297 companies in the Defense Industry were utilized as samples. Results: It turned out that CI had significant impacts on Management Infra(MGT_Infra), Process Management(PM), Human Resources Management(HRM) and Communication(COMU) and had an indirect impact on the enterprises' financial performance through the parameters of HRM and Communication. Meanwhile, it turned out that between CI and non-financial performance, there was a direct effect, and there was also an indirect effect through the variables of the Management Infra and Communication. Conclusion: It turned out that CI had a positive effect on SCQM as a proactive driver and that they had significant relationships with BP(financial, Non-financial), both financial performance and non-financial performance. However, PM did not have a significant relationship of effect with BP because of the character appearing by the evaluation method of military supplies for the conformity to the specifications.

The purpose of this study is to explore relationships among the structural elements of Science Classroom as Community of Practice (SCaCoP). For this, we investigated the case of small-group activities in practical work of elementary school science in a qualitative way based on the five structural elements of SCaCoP, such as responsibility for learning, common interest, open participation, mutual relationship, and practice. We observed and interviewed five small-groups during five lessons with video- and audio- recording to collect data. The results of analysis are as follows. First, 'mutual relationship' was a necessary-condition for 'open participation.' We also found that 'common interest' has two dimensions related to their interest and related to learning topic. The former interacted with 'open participation,' and the latter was influenced by 'responsibility for learning. Lastly, 'practice' enhanced the features of other elements with dynamic relationships. Based on these results, we suggested the relationships among the structural elements of SCaCoP and discussed implications related to the perspective that regards learning as participation.

Objective: The aim of this study was to examine the mediated effect of teacher-infant relationships between teacher efficacy and infant's adjustment to child care centers. Methods: A total of 137 child care teachers that lived in Gwangju and Jeollanamdo participated in this study. They were asked to answer two survey questionnaires for two infants. The data were analyzed using analysis of frequency, Pearson's correlation coefficient, and hierarchical multiple regression analysis. Results: The main results are as follows. First, teacher-infant relationships partially mediated the relationship between teacher efficacy and two sub-factors (prosocial behavior and day work adjustment) of adjustment in child care centers. Unlikely as it was, several sub-factors such as positive emotion, peer adaptation, and self-strength were fully mediated by teacher-infant relationships. Conclusion: The present study suggests that it is necessary to improve teacher-infant relationships with teacher efficacy in order to improve infants' adaptation to daycare. In addition, it should be understood that the structural relationship of the influence factors is different depending on the sub-factors of the child care adjustment.
