In recent years, Chinese government established 4 pilot zones at Shandong, Zhejiang, Guangdong, Fujian. The national marine development pilot zones policy is formed in order to promote development of Chinese marine economy, as if Chinese government selected 4 special economic zones as the policy experiment areas for economic structural reform at the beginning stage of reform and opening-up. This article utilizes the policy-making theory of Incrementalism Model and aims at searching for the essence, historical formation process, implementation state, implications of 4 Chinese marine economic development pilot zones policy. Moreover, the prospect of their future development is analyzed. The marine pilot zone policy has the following features: new development model with advanced industries and sciences & technology, highly civil participation, plural policy goals. These research results would be able to contribute not only to getting better understanding of China's marine industry policy, but also to drawing lessons for the construction of Korea's marine economic special zone in the viewpoint of policy transfer.

As culture technology is recognized as the important element of national industry, the necessity of the related policy development for enhancement of culture technology is magnified. In this study, we use conjoint analysis to investigate how the researchers from industry and academia think differently on the importance of several attributes in government-supported culture technology research project such as research period, size of research fund, inter-affiliated research requirement and interdisciplinary research requirement, and preference on those attribute levels. Also, we describes how a simulation experiment is designed to simulate participation shares of four alternative hypothetical research project profiles. This study will help establish the more effective policy of the national research program by understanding the preferential differences between industry and academia on the research project attributes.

This paper overviews the concept of the strategic niche management, which emphasises the social aspects of new technologies and calls for relevant government policies for socio-technical transition. Hydrogen energy technologies remain in the niche level, thus the SNM perspective is appropriate to be applied. The reason why, and the way how to see hydrogen as a socio-technical niche are discussed, followed by an analytic argument on hydrogen policies and their SNM characteristics. Final part of the paper deals the design of the socio-technical experiment. It is expected that this paper would contribute to not only policy development but also improving understandings on the socio-technical nature of hydrogen energy of hydrogen community.

To solve the policy problem between transportation and environment in trade-offs, above all, it is necessary to understand the complicated relationship between transportation and environment clearly before selecting policy alternatives. From this point of view, this study will propose the logic structure to examine the complex interaction of transportation and environment and investigate theoretically what kinds of impact would appear by the air related polices. In this research, we used ’system-dynamics’ which investigates the complexity through the flow of information and materials and the interaction of elements, which constitutes systems. System Dynamics is an approach that the variables to decide structural relationship in a system affect one another not in only-way but in inter-way and the power of influence changes time by time. This research is trying to examine the complex interaction of transportation and air pollution. For achieving this purpose, causal maps in System Dynamics approach were used. The main issues are as follows; first, to investigate the dynamic relationship between transportation and air pollution caused by exhaust emission gas. Second, to structuralize the logic of simulation to experiment the impacts of policies to relieve air pollution.

Purpose : The aim of this article is to describe the nurses' experiential learning mechanism on patient safety. Methods : To analyze nurses' learning experiences on patient safety cases, a focus-group interview method was used. The Kolb's experiential learning model was used as a reference model. Findings : Without deep reflective reasoning about specific experiences, there is no creative or innovative solutions to experiment actively. Nurses are likely to be reluctant learners when there is no systemic support from formal departments which is in charge of patient safety and quality of care. Conclusion : In order to build patient safety culture in hospital, there should be efforts to make nurses as active learners on patient safety as well as to build learning environments in medical units.

National information policies have to be flexible： to anticipate changes and turn them to good advantage, to scrap old approaches as they cease to be relevant and to experiment with new approaches as they cross the horizon. This flexibility implies‘a liveliness of mind’and‘a spirit of enterprise’at the policy-making level, two qualities that do not abound and which must be in demand for other national policies.

Due to the improvement of modern information technologies, sharing stock information among the supply chain members is a common practice nowadays. Many companies are planning to adopt the information systems to possess the real-time shared stock information. Thus, it is needed to quantify the value of shared stock information. The purpose of this paper is to evaluate the value of the shared stock information for two-echelon distribution systems. Existing reorder policies can be classified into installation stock policies and echelon stock policies. Since installation stock policies do not utilize the shared stock information, and both classes of policies may show poor performances for distribution systems, we cannot evaluate the value of the shared stock information with the existing policies. Thus, we provide a new type of reorder policy, named order risk policy. We define the order risk using marginal analysis, and prove the optimality. Through computational experiment that compares the order risk policy with the existing policies, it is shown that a significant cost reduction is achieved with the effective utilization of the shared stock information. We also show the effect of the system characteristics on the value of the shared stock information.

In this paper, we consider multi-item inventory management. When managing a multi-item inventory, we coordinate replenishment orders of items supplied by the same supplier. The associated problem is called the joint replenishment problem (JRP). One often-used approach to the JRP is to apply a can-order policy. Under a can-order policy, some items are re-ordered when their inventory level drops to or below their re-order level, and any other item with an inventory level at or below its can-order level can be included in this order. In the present paper, we propose a method for finding the optimal parameter of a can-order policy, the can-order level, for each item in a lost-sales model. The main objectives in our model are minimizing the number of ordering, inventory, and shortage (i.e., lost-sales) respectively, compared with the conventional JRP, in which the objective is to minimize total cost. In order to solve this multi-objective optimization problem, we apply a genetic algorithm. In a numerical experiment using actual shipment data, we simulate the proposed model and compare the results with those of other methods.

The Philippines in 2016 showed the highest GDP growth rate among Southeast Asian countries, in spite of domestic and international turbulence caused by the war on drugs and unexpected foreign policies after Duterte's presidency. The social contexts and political dynamics behind 'Duterte phenomenon' have raised key questions and issues to other countries including Korea, as to democracy and politics in current neoliberal challenges. The Philippines' choices for independent foreign policy and challenges against existing hegemony would continue to draw attention, particularly on whether this would end in an experiment of a country or initiate an alternative power block among neighboring countries and ASEAN communities.
