Marketable permit system (MPS) is a economic incentive instrument that allows polluters to achieve static and dynamic efficiency, However, Korea's atmospheric regulations are primarily based upon command and control (CAC) system and partly upon economic incentive instruments, which fail to realize its relative effectiveness, Accordingly, an introduction of MPS has been recommended with the cost effectiveness analysis in numerous studies, The literature, however, did not consider the relationship between MPS and the existing regulations, which is a key factor for the successful introduction of MPS, This paper provides a set of principles to judge how the existing regulations are reconciled with the introduction of MPS, In addition, authors execute an empirical study to show MPS's cost effectiveness when regulators apply MPS in Ulsan area for the abatement of sulfur dioxide, The results suggest that the regulations such as fuel regulation should be excluded when implementing MPS, and a flexibility in legal and regulatory system is to be required in order to secure a successful implementation of MPS.

Strategic agility plays an important role in maintaining a competitive advantage for companies, where information systems are introduced. The purpose of this study is to analyze the impact of the introduction of the information system on the strategic agility of the company through the analysis of the "H" resort, which has recently built the information system. Research shows that the introduction of resort management information systems promotes the level of strategic sensitivity, collective commitments and resource liquidity, which are key elements of strategic agility. This study confirmed that the establishment of resort information system has a positive effect on practitioners who want to create strategic agility. However, this study is a single case study and it is difficult to argue that the introduction of information systems is a positive for the strategic agility approach.

As the advent of the Fourth Industrial Revolution and Information Age, companies are in the state of infinite competition due to the rapidly changing technological environment and fierce competition. In this situation companies are making efforts to gain the competitive advantage by introducing information systems. Supply Chain Management (SCM) is considered a method to gain a competitive edge in rapid change. In fact, companies that already have introduced the SCM system are achieving company renovation with positive effects such as increase of sales stock reduction on-time delivery cost reduction and improved efficiency. This study was started to investigate the resistance that occurs in introducing the SCM system for small and medium-sized manufacturing industries that have not yet introduced the SCM system despite the importance of the SCM system, and to check the effect on the intention of the introduction. As the result of this study, the first is that the company has the higher technological innovation, the more positive the effect on Relative advantage Compatibility Perceived risk, Complexity. Second, The compatibility of the SCM system was rejected in innovation resistance, but it is adopted with the highest impact in the introduction intention. In addition, the mediating effect of innovation resistance was also rejected, confirming that if the SCM system is compatible for the company, it doesn't affect the resistance and is the biggest factor to consider in the introduction of the SCM system. Third, the perceived risk of the SCM system doesn't directly affect the intention to introduce, but has an indirect effect when mediation innovation resistance.

Current OSH system was analyzed in this paper to explain why high fatal incidents and disasters are continuously repeated for recent years in Korea. It was found that we have Dichotomous Perceptional Misconception of prevention before accident and compensation after accident and there is a significant lack of proper feed­back reward system for OSH performance. It was assumed that no reduction of accident rate and fatality rate have not been achieved recently despite of a great effort and increased resource allocations. Some statistics for proving weak punishment were analyzed. In the current system, the will of administrative agency would have been very limited particularly in the legal aspects. The Industrial Safety and Health Act is not suitable to after-injury punishment for employer and/or corporate since it is based on a framework for enforcement of prevention. Based on these analyses, it was concluded that there was a need to consider a special law for Corporate Accountability for Fatal Accidents. Because it is necessary to consider seriously for introduction of a new legal system for after injury punishment to repair the current system where it was found lack of proper feedback system. Also, there was no proper sanction measures for corporate with the current OSH legal system, and the most urgent problem in OSH area is the high fatality rate. it is necessary to consider seriously for introduction of a new legal system for after injury punishment. Also, there is no proper sanction measures for corporate with the current OSH legal system, and the most urgent problem in OSH area is the high fatality rate.

The analytic test results are as follows. This thesis categorized into independent variables, multiple factors, such as asset attributes, cost reduction expectation, corporate IT competence, service qualities, system adequacy, information security, easy system management, uncertain IT, supplier capacity, intra-industry competition. And, this research thesis categorized into moderators, the factor, such as the adequacy between suppliers and customers industries. And, this categorized into dependent variables, multiple factors, such as the effects of ASP introduction. But, it was analyzed that only cost reduction expectation out of independent variables had not positive effects on the effects of ASP introduction. And, it was confirmed that the higher communications between suppliers and customers' industries, and the higher fulfillment of contracts, suppliers' service qualities, and suppliers' cooperation with customers had the adjusting effects on factors of ASP-based introduction.

The shipbuilding process is changing due to changes in the development environment and technological requirements for military ships. This would also hold true for a submarine, because its shipbuilding process includes complicated design and construction conditions. System improvement efforts for the design and construction of military ships have continued with the goal of overcoming these conditions. At present, the Korea Navy is developing a 3,000 ton-class Korean type submarine, and its design is progressing by the introduction of a full 3D-ship CAD system. Although the 3D modeling system was introduced for effective design realization through the introduction of collaborative design and active utilization of M&S (modeling and simulation), the introduction effects are not yet generally obvious, according to the characteristics of ship design. The present paper discusses the collaborative environment for developing a submarine to enhance this. This paper proposes the architecture and data structure of a system for realizing collaborative design and discusses a case system developed on the basis of this.

With the obligation of information system supervision and an increase in supervision demands, the quality improvement in information system supervision has been of significance, and the supervision system has been enhanced in the way of preventing information systems from being poorly established. In the meantime, recently the supervision industry has received administrative punishment due to violation of supervision guidelines and false reports. As a result, the introduction of the responsible supervision of information systems to strengthen the rights and duties of supervisors and supervision corporations has been discussed by supervision corporations. Therefore, this work was intended to propose success factors to introduce responsible supervision in the information system supervision sector, and thereby contribute to the introduction of responsible supervision system that plays a successful role in preventing poor supervision and establishing information system business. The success factors of the responsible supervision of information systems, proposed in this work, were categorized into legal system, standardization of supervision work, those concerned with supervision. And, detailed success factors of each category were proposed, and on the basis of that, the success model to introduce responsible supervision successfully was proposed.
