The Kanban system in Just-In-Time (JIT) production is very effective in reducing the inventories when consumption rate of the final product is relatively stable. When large fluctuations exist in the consumption rate, a new production ordering policy in which the production order quantity is determined by smoothing the demands exponentially is more suitable. This new ordering policy has not been investigated sufficiently. In this research, a multi-stage production and inventory system with stock points for materials and finished items located at each stage is considered. Approximations of average inventories at each stage in the system are derived theoretically. Numerical simulations are carried out to assess the accuracy of approximations and to evaluate the effectiveness of the new ordering policy as compared with the Kanban system. As a result, it is shown that the new ordering policy can achieve significantly lower inventory costs than the original Kanban system. The new ordering policy thus emerges as a key concept for an effective supply chain management.

It is essential to have adequate legal regulations to achieve the policy objectives in libraries. This study aims to analyze the structure and critical amendments of the Library Act (Law No. 18547), which was comprehensively revised on December 7, 2021 and has been in effect since December 8, 2022. This analysis examines the normative validity and effectiveness from a policy legislation perspective. As a fundamental law, we explore whether the Library Law possesses legal validity and can contribute to achieving policy objectives by elevating the societal value and qualitative improvement of libraries from an effectiveness standpoint. The analysis results suggest proposing enhancements to the content of objectives and fundamental principles, specifying the responsibilities of the state and local authorities, improving the library policy system, and enhancing the substantial influence of the National Library Commission.

The Korea Emissions Trading Scheme ( K-ETS), which manages roughly 70% of the greenhouse gas emissions in South Korea, was initiated in 2015, after implementation of its 1st basic plan and the 1st allocation plan (2014) for the 1st phase (2015-2017). During the three and a half years since the launch of K-ETS, there have been critical policy change such as adjustment of the institutions involved, development and revision of the 2030 national GHG reduction roadmap, and change in the allocation plans. Moreover, lack of liquidity and fluctuation of carbon prices in the K-ETS market during this period has forced the Korean government to adjust the flexibility mechanism and auction permits of the market stability reserve. To evaluate the policy change in the K-ETS regarding conformance to its objectives, this study defines three objectives (Environmental Effectiveness, Cost Effectiveness and Economic Efficiency) and ten indicators. Evaluation of Environmental Effectiveness of K-ETS suggests that the national GHG reduction roadmap, coverage of GHG emitters and credibility of MRV positively affect GHG mitigation. However, there was a negative policy change implemented in 2017 that weakened the emission cap during the 1st phase. In terms of the Cost Effectiveness, the K-ETS policies related to market management and flexibility mechanism (e.g. banking, borrowing and offsets) were improved to deal with the liquidity shortage and permit price increase, which were caused by policy uncertainty and conservative behavior of firms during 2016-2018. Regarding Economic Efficiency, K-ETS expands benchmark?based allocation and began auction-based allocation; nevertheless, free allocation is being applied to sectors with high carbon leakage risk during the 2nd phase (2018-2020). As a result, it is worth evaluating the K-ETS policies that have been developed with respect to the three main objectives of ETS, considering the trial?and?error approach that has been followed since 2015. This study suggests that K-ETS policy should be modified to strengthen the emission cap, stabilize the market, expand auction-based allocation and build K-ETS specified funds during the 3rd phase (2021-2025).

The study is intended to examine awareness of safety as a differentiated service strategy and t to induce offer of more competitive services to the internal and external consumers in service industry of the South Korea. In the pursuit of this purpose, the typical occupations of the service industry targeted hotel employees and this study investigate the policy effectiveness of security management in Korea hotels. Specifically, this study was conducted by survey and involved major hotel(Seoul, Busan, Gyeongsangnam-do, Gyeongsangbuk-do) across the country. This survey went through feasibility study by major hotels managers. The results were as follows: Findings of the study suggested that most of disaster management stages did not have a statistically significant relationship with the policy effectiveness of security management. Only, repair stage have significant impact on the policy effectiveness of security management. This finding was found to be attributable to the fact that hotel employee would be concentrated in the tangible results of security management.

The aim of this study sets out to discover a desirable form of public centers among the alternative ones and make a health center model. Especially, this study attempts; (i) to investigate factors that affect the performance of health centers; (ii) carry out cost-effectiveness analysis (CEA) for the various type of health centers; (iii) identify innovative strategies to increase the use of health center. Cost-effectiveness analysis is used to compare the performance of all the centers. The following is taken to create the index. Wi = Ti x Mi x Eij (Wi: weight for service item I, Ti : time spent for service I, Mi ; number of health personnel involved in service I, Eij : years of schooling for personnel j in providing service I). As a result of these analyses, policy options as follows are recommended; (i) proper manpower, especially public health physician (oriental medical doctor), should be enough to provide health care adequately; (ii) facilities ad equipments in the health center should be provided sufficiently. (iii) the utilization of health centers should be raised by active operation of mobil service, community participation and health education program. Ultimately health centers in public sector are to be fostered for the promotion of health care by enhancing the financial and quality, continuity and efficiency of health services.

This study was conducted to evaluate the effectiveness of team system at university hospitals in Korea. Data were collected from administrative and medical support workers at 4 university hospitals through the self-administered questionnaires and analyzed using frequency analysis, t-test, and oneway ANOVA. The results of this study are as follows. First, teams with higher team management characteristics show higher level of quality of work life and performance effectiveness. Second, teams which consist of members with variety background and skills show higher level of quality of work life and performance effectiveness. Third, team which have the higher autonomy, technology variety, job significance, and feedback show higher team effectiveness. Fourth, team which have team leaders with higher leadership score show higher level of quality of work life and performance effectiveness. Fifth, there are differences in team effectiveness in terms of sicio- demographic variables such as average age, position, and tenure of team members, length of team system, and team size. Sixth, the job autonomy of team members and the leadership of team managers have significant effects on the quality of work life variables. Seventh, the leadership of team leaders, job autonomy of members, and individual contact between team managers and members have significant effects on the team performance variables. In conclusion, in order to increase the effectiveness of team system in university hospitals, it is required to consider the characteristics of team management, diversity of team members, the autonomy of team members, the leadership of team manager, and the socio-demographic factors of team members.

In this study, we analyze how the difficulties of e-learning firms' management affect to the maturity of the practical use of e-learning research & development (R&D) policies. And we explore the method that can enhance the effectiveness of policy. In the pursuit of this purpose, we use the 2012 South Korea e-learning industry survey data. Using variables of recognition of policy, experience of policy, and intention to use of policy, we find the maturity model of six stages. And we analyze the impact of the difficulties of operation, technology development, marketing to the maturity model. As a result, the more e-learning firms have problems of fund management and technology commercialization, they are located the higher maturity of the use of policy. Based on the results of these studies, we discuss the implication for how can enhance the effectiveness of policies.

The Ministry of Construction and Transportation(MOCT) announced the General Policy for Effective Implementation of Public Construction Projects(the Policy) in 1999. Fifty two regulations were amended to embody the Policy between 1999 to 2001 Then MOCT performed the analysis to show the quantitative performance of the Policy. However, there has been no effort to evaluate the degree of implementation and effectiveness of the Policy so far. Therefore, this paper was initiated to perform the survey on industry's perceptions, implementation degree, effectiveness, and satisfaction of the Policy. The result shows that most policies were implemented in the construction industry but some policies were little adopted. Therefore, this paper proposes to update the Policy based on the survey results to effectively implement public sector projects.
