The Fukushima nuclear incident of 2011 served as an external shock that prompted Japan to reform its nuclear energy sector. The collusive relationship between the regulators within the Japanese government and the regulated power industry, as well as the lack of institutional independence of the regulatory agency, had derailed Japanese efforts to reform the sector for decades. The Fukushima crisis exposed these deeply-entrenched flaws in the system, causing public distrust and anger toward the government and the nuclear power sector. This paper discusses the institutional reform measures the Japanese government introduced in the wake of the Fukushima crisis to recover public confidence and revamp the sector to prevent future disasters. The paper also discusses the challenges the Japanese government faces on its road to a successful implementation of nuclear sector reforms.

Environment education, which is a principal solution to environmental problems in the world, is being practiced in Korea through the national curricula for primary and secondary schools. However, it hasn't been effective so far to practice environment education within those schools where a variety of subjects are taught. The purpose of this study is to look for the possibility of practicing environment education and thereby to make some suggestions for effective environment education in the field of English education, which doesn't seem to have a close relationship with environment education. This study first specified prospective contents of environment education by analyzing the Seventh National English Curriculum. Then, on the basis of them, the study explored how to practice environment education in the field of English education. Finally, for effective environment education, it made some suggestions and emphasized the importance of consistent efforts.

The purpose of this paper is to investigate the relationships among transformatonal leadership, gropefficacy, and group performance. A total of 321 empolyees of a fire and marine insurance frim in Seoul anonymously completed the Multifactor Leadership Questionnaire-Form V, which consists of three factors(charisma, individualized consideration and intellectual stimulation) for transformational leadership, and two factors(contingent reward and management by exception) for transactional leadership. The sample, which largely consists of sales supervisors and salesmen, includes 41 sales office branches. The findings of the study are as follows. Transformational leadership is closely associated with group-efficacy and group performance. That is, there are significant correlations between transformational factors and group-efficacy, between the factors and group performance, and between group-efficacy and group performance. A stepwise multiple regressio analysis revealed that transformational leadership augmented the subordinates's extra efforts. It was also found that group-efficacy was mediating the relationship between transformational leadership and group performance. The managerial implications of these findings and future directions of research are also discussed.

In this paper, we consider an optimal allocation of constant service efforts in queueing network to maximize the system throughput. For this purpose, using the perturbation analysis, we apply a stochastic optimization algorithm to two types of queueing systems. Our simulation results indicate that the estimates obtained from a stochastic optimization algorithm for a two-tandem queuing network are very accurate, and those for closed loop manufacturing system are a little apart from the known optimal allocation. We find that as simulation time increases for obtaining a new gradient (performance measure with respect to decision variables) by perturbation algorithm, the estimates tend to be more stable. Thus, we consider that it would be more desirable to have more accurate sensitivity of performance measure by enlarging simulation time rather than more searching steps with less accurate sensitivity. We realize that more experiments on various types of systems are needed to identify such a relationship with regards to stopping rule, the size of moving step, and updating period for sensitivity.

The purposes of this study and to develop the model to prove the structural relationship between service orientation and customer satisfaction, to find out the mediation variables between them, to survey and analyze their roles empirically, and to prove the probability of applying the strategic frame to all hotels in Korea. For these purposes, the author developed a structural model which consists of six variables. The data were collected from 7 hotels and analyzed with AMOS program. The findings can be summarized ad follows : First, the higher customer expectation, the lower customer satisfaction. Second, the higher customer expectation, the higher customer perceived quality. Third, the higher customer perceived qualify, the higher customer satisfaction. Fourth, the higher customer perceived quality, the higher customer perceived value. Sixth, the higher customer satisfaction, the lower customer complaint. Seventh, the higher customer satisfaction, the higher customer loyalty.

The rapid expansion of regionalism has resulted in the creation of blocs of the global economy, so that those countries not belonging to one or more blocs can be discrimiated. Though signed on the bill of FTA with Chile, Korea is actually alienated from major stream of the blocs. Therefore, Korea government makes efforts to contract more FTAs with countries such as Singapore and Japan, others. FTA is believed to be an important method to secure export and national competitiveness. Therefore, we need to exactly understand critical issues and the long-run effort of FTA. This paper tries to find out important issues and potential strategies relating to electronic commerce in Korea's FTA with other countries. In these means, relationship between FTA and e-Trade are closely related to global business chance. In these means, we should use FTA potentials for encouraging global commerce by e-Trade and develop e-FTA in the foreseeable future.

Firms seldom survive and prosper solely through their individual efforts. Each firm's performance depends upon the activities and performance of others and hence upon the nature and quality of the direct and indirect relationships a firm develops with its counterparts. Textile companies have tried to improve their organizational competitiveness in order to survive in the digital age global market. The challenge in textile supply chain management is the development of collaboration network which accommodates diverse concerns of various participants while explicitly recognizing interdependencies and promoting effective relationship management. Major contents of the study are as follows. First, ideal collaboration network model from the supply chain of the textile industry is suggested. Second, utilizing the collaboration model, A framework for textile e-marketplaces supply chians is designed to improve customer services and delivery time, to promote information sharing, and shorten product life cycle time. The framework suggested is expected to promote corporate innovation and information sharing, generate infrastructure which provides appropriate communication and operations capabilities for the textile companies.

This paper traces the issue of key account management success which has regarded as a pressing concern of many companies' sales efforts at the organizational business-to-business context. Based on the extensive review of extant literatures, we introduced a theoretical framework that covers the antecedents and consequence of key account management success. We theorized the conditions under which organizational and relational factors influence the success of key account management approach. We endeavor to develop research propositions for each construct and provide necessary suggestions to isolate a platform for future empirical research. Beyond this span, an improved understanding from this framework will help developing policies for successful key account management approach.

Hotel industry publications demonstrate a keen interest in the revenue enhancing potential of yield management, but there has been little research on the extent to which this pricing technique is actually utilized by hotel general managers. This research tests the proposition that there are eight basic elements of yield management in hotels. The degree to which yield management is practiced is indicated by the extent that these eight elements are in place. It was found that there is a positive relationship between a managers perception of his or her own yield management utilization and the extent to which the eight elements are used. It was also found, however, that while 77% of hotels claim to be utilizing yield management techniques extensively, very few are using all of the basic elements in their efforts to maximize revenue.

Model updating is a very active research field, in which significant efforts has been invested in recent years. Model updating methodologies are invariably successful when used on noise-free simulated data, but tend to be unpredictable when presented with real experimental data that are-unavoidably-corrupted with uncorrelated noise content. In this paper, Reanalysis using frequency response functions for correlating and updating dynamic systems is presented. A transformation matrix is obtained from the relationship between the complex and the normal frequency response functions of a structure. The transformation matrix is employed to calculate the modified damping matrix of the system. The modified mass and stiffness matrices are identified from the normal frequency response functions by using the least squares method. Full scale pseudo dynamic pier test is employed to illustrate the applicability of the proposed method. The result indicate that the damping matrix of correlated finite element model can be identified accurately by the proposed method. In addition, the robustness of the new approach uniformly distributed measurement noise is also addressed.
