Space development and utilization must be conducted within a framework of "peaceful uses" principle under Space Treaty. Japan ratified the treaty in 1967, and interpreted "peaceful uses" as "non-military uses" then. A ghost of "peaceful uses" principle has been hung over Japan up to the moment. Japan's space development and utilization has been conducted with genuine academic interest, and therefore Japan did not introduce space infrastructures to national security policy and did not facilitate growth of space industry. When the Cold War ended, Northeast Asian security environment makes Japan difficult to maintain an interpretation as "non-military uses". Besides the change of external security environment, the domestic industry situation and a series of rocket launching failure needed reexamination of Japan's space policy. Japan is gradually changing its space policy, and introducing space infrastructure in a national security policy under a "generalization" theory that gave a broad interpretation of "peaceful uses" principle. Council for Science and Technology Policy (CSTP) adopted a basic strategy of Japan's space policy in 2004. Since then, a long-term report of Japan Aerospace Exploration Agency (JAXA), an investigation report of Society of Japanese Aerospace Companies (SJAC) and a proposal of Japan Business Federation (JSF) were followed. Japan will promote space development and utilization in national security policy with a "strictly defensive defense" strategy and "non-aggressive uses"principle for protection of life and property of Japanese people and stabilization of East Asian countries.

Opportunistic scheduling provides the capability of resource management in wireless networks by taking advantage of multiuser diversity and by allowing delay variation in delivering data packets. It generally aims to maximize system throughput or guarantee fairness and quality of service (QoS) requirements. In this paper, we develop an extended proportional fair (PF) scheduling policy that can statistically guarantee three kinds of QoS. The scheduling policy is derived by solving the optimization problems in an ideal system according to QoS constraints. We prove that the practical version of the scheduling policy is optimal in opportunistic scheduling systems. As each scheduling policy has some parameters, we also consider practical parameter adaptation algorithms that require low implementation complexity and show their convergences mathematically. Through simulations, we confirm that our proposed schedulers show good fairness performance in addition to guaranteeing each user's QoS requirements.

In this paper we propose a QoS policy, which is based on both DSCP and SPQ, appropriate to TPS users on optical subscriber network. Then we experiment and evaluate QoS policy through the test bed which emulates real optical subscriber network. In order to perform effective and real experiment on test bed we make test traffic equivalent to 400 TPS users and give it to test bed. The experimental result shows that no packet loss in real time service traffic such as voice, IPTV occurs during more than 4 hours. We think that our proposed QoS policy is a proper method which guarantees the service quality of real time services on optical subscriber network.

While the Vendor-Managed Inventory(VMI) is a convenient inventory replenishment policy for the customer company, the supplier usually bears the burden of higher inventory and urgent shipments to avoid shortage. Recently some manufacturers begin to fix the production schedule for the next few days (such as three days). Utilizing that information can improve the efficiency of the VMI. In this study, we present a myopic optimization model using a mixed inter programming; and a heuristics algorithm. We compare the performance of the two proposed methods with the existing (s, S) reorder policy. We consider the total cost as the sum of transportation cost and inventory cost at the customer's site. Numerical tests indicate that the two proposed methods significantly reduce the total cost over the (s, S) policy.

오늘날 BRICs 국가들이 효과적인 정부의 개입과 세계시장의 활용을 통하여 급속한 성장을 이루었음에도 불구하고 동일한 정책을 선택한 수많은 제 3세계 국가들이 여전히 저성장의 늪에 빠져 있다. 따라서 본 연구는 특정한 정책의 선택을 경제성장의 결정요인으로 보기 보다는 정책의 이행역량을 중심으로 살펴보아야 한다는 관점 하에서 근년 들어 자유주의적 경제정책에서 적극적 정부개입으로 정책을 선회한 에콰도르에 대한 사례연구를 실시하였다. 에콰도르는 꼬레아 정부의 등장 이래 정부의 적극적 개입을 통한 산업화를 추구하고 있다. 본 연구는 이러한 정책적 선택이 경제성장을 가져올 수 있는지 여부 그 자체 보다는 에콰도르가 종합적으로 이를 성공적으로 수행할 수 있는 역량을 보유하고 있는지 분석을 목적으로 한다. 즉, 에콰도르 경제개발정책의 질적수준과 그 이행능력을 평가함으로써 개도국 성장역량의 결정요인을 미시적 수준(정책의 합리성, 일관성, 실현가능성, 행정부 역량, 정책의 집행구조 등)에서 살펴보고 있다. 본 연구에서는 에콰도르의 산업 및 무역정책이 충분한 현실 정합성을 확보하지 못하고 있으며 전략산업의 선정도 지나친 경직성으로 인하여 환경변화에 따른 융통성을 결여하고 있는 것으로 평가되었다. 또한 에콰도르의 정책수단들이 매우 일반적인 인센티브 제도와 기술적 지원에 그치고 있으며 산업의 구축에 필요한 자원의 투입과 관련한 구체적 방안을 결여하고 있는 것으로 평가되었다.

This paper focuses on establishing strategies to ensure entry to the Uzbekistan in the process of developing business opportunities and managing industry. The study provides initiatives to maintain industrial competitiveness as well as policy guidance for entry and management on the Uzbekistan's industry. The most prominent feature of Uzbekistan's industrial development policy during the past decade is that it has undertaken an integrated policy approach to development which brought about sustainable economic development. In this development process, trade policy, manpower development policy, and technology policy were well coordinated and complementary to industrial policy in the Uzbekistan. This paper attempts to analyze Uzbekistan's custom and system in terms of broad industrial policy concept through resource and economic environment of Uzbekistan and to derive some lessons of market evaluation and policy implication for Korean government and industrial line.

Objectives: This study examined the status of children's favorite foods intake and the relationship with the policy environment based on the Special Act on Safety Control of Children's Dietary Life for suggesting a supportive policy strategy. Methods: The subjects were 4th grade students (n=1,638) in elementary school from 45 schools collected from seven areas (Seoul, Daegu, Daejeon, Gyeonggi, Chungnam, Jeonbuk, and Gyeongnam). The children participated in a self-administered questionnaire survey in class under the supervision of the teacher. The questionnaire consisted of items, such as social demographic characteristics, frequency of intake of the children's favorite foods, and policy cognition. A t-test and ANOVA were applied to explore the relationship between the frequency of children's favorite foods intake and policy cognition. The survey was implemented from August 2016 to September 2016. Results: For the boys, the frequency of 'high-calorie low nutrient foods intake' (HCLN) was significantly higher than that of the girls (p<0.01). For the children who received information on their favorite foods from the internet, the frequency of HCLN was higher than the other sources (p<0.01). The time of TV viewing and computer usage, and smartphone usage was associated with a higher frequency of HCLN, and a lower healthy favorite food intake (all p<0.001). The intake frequency of healthy favorite foods indicated a positive correlation with the policy cognition, including policy perception, usefulness, necessity and buying intention, and educational experience. Conclusions: This study showed a correlation with the frequency of children's favorite foods intake and policy. In particular, the frequency of children's healthy favorite foods intake indicated a meaningful relationship with the policy than the frequency of HCLN. This study also found that the consumption of children's healthy favorite foods was positively correlated with the educational experience. To develop a supportive policy for a good dietary environment for children, there is a need to focus on how to collaborate with multiple levels of influences, such as the national level, school level, and family.

Aviation/tourism industry has a unique characteristic of high inter-dependance between customer and service-provider. It is the mental condition of service-provider that could influence on the attitude of the service-provider. Thus, it is important to manage the mental condition of the service employees to enhance a company's financial performance. This paper tries to analyze the combined model of both policy acceptance and service profit chain(SPC) models. First, service policy acceptance model tells how the service policy acceptance, which consists of policy compliance, trust, participation and policy failure, would influence on SPC model. According to empirical research, it was found that both the employees' policy compliance and the policy trust have a positive significant impact on their participation on service policy. In the policy acceptance model, the employee's voluntary participation based on their trust and compliance of the policy was proven to have a positive effect on increasing job satisfaction and customer orientation. Regarding SPC model, their participation in the policy had the strongest impact among variables on customer orientation. Such results implies the employees' participation on the policy could become the starting point to enhance the customer value.
