  • Proportional Fair (PF) share policy has been adopted as a downlink scheduling scheme in CDMA2000 l×EV-DO standard. Although It offers optimal performance in aggregate throughput conditioned on equal time share among users, it cannot provide a bandwidth guarantee and a strict delay bound. which is essential requirements of real-time (RT) applications. In this study, we propose a new scheduling policy that provides quality-of-service (QoS) guarantees to a variety of traffic types demanding diverse service requirements. In our policy data traffic is categorized Into three classes, depending on sensitivity of Its performance to delay or throughput. And the primary components of our policy, namely, Proportional Fair (PF), Weighted Fair Queuing (WFQ), and delay-based prioritized scheme are intelligently combined to satisfy QoS requirements of each traffic type. In our policy all the traffic categories run on the PF policy as a basis. However the level of emphasis on each of those ingredient policies is changed in an adaptive manner by taking into account the channel conditions and QoS requirements. Such flexibility of our proposed policy leads to offering QoS guarantees effectively and. at the same time, maximizing the throughput. Simulations are used to verify the performance of the proposed scheduling policy. Experimental results show that our proposal can provide guaranteed throughput and maximum delay bound more efficiently compared to other policies.

  • Passing 26 years from 1970 when the first satellite was launched into the orbit, Japan developed and successfully launched H-II from Tanegashima Space Center in 1994. During those period, Japanese space policy has experienced a big shake from independent development to technology import from the US, and back again to independent development. In general, the H-II rocket which was manufactured by 100% domestic technology, brings Japan from the old era (experimental stage) to the new era (practical use stage). Fundamental Policy of Japan's Space Activities, which decides such policy as mentioned, was revised in January, 1996 this year after an interval of 7 years. This revised outline confirms the result of Japanese space technology until present and identifies the future direction and framework of her space activities for a period of coming ten years on the basis of a ong-term perspective towards the 21st century. However, when comparing with the last Fundamental Policy in 1989, there seems no big change in it, and a long-term perspective is also not seen there. The description varies on some important points in international space law, like international cooperation, protection of environment, commercial use, etc. In addition, the immaturity as well as the necessity of broader discussion are felt because neither this Fundamental Policy nor The National Defense Program Outline treated any national and international security matters concerning outer space. Considering the present time when Japan enters into the practical use of outer space, such as application, commercial use and launching service, etc, it is doubtful whether new Fundamental Policy was properly planned or not. It seems necessary to use several measures by which the public opinion, opinions from industry and debate on the security are reflected in the policy making.

  • In Korea, there are many cases where policy decisions are not made even though it is a big social issue. Usually, the reasons for such delay in policy making are cases where it is delayed to go through an appropriate policy procedure, and there are cases where the consent of stakeholders is not obtained. But, this study intends to suggest that a few policy delay in Korea can be explained by intentional non-decision-making by the government. Non-decision making is being made as a strategic and active strategy of the government. In this study, the case of Lotte Shopping Mall in Sangam was analyzed from the point of view of non-decision making. As a result of analysis based on factors such as the existence of elite, purpose, policy tool, policy process, and result, it can be assumed that the policy delay of the Lotte Shopping Mall was caused by the government's active strategic decision. The government's strategic non-decision-making, which is distinct from passive administration, needs to be reviewed in various ways in the future.

  • Two conditions should be satisfied if fiscal policy is to stabilize economic cycles; proper policy timing and significant policy effect. This paper evaluates whether the policy timing has been proper in Korea by investigating the correlation between fiscal policy stance and economic conditions. We first calculate quarterly FIs (Fiscal Impulse) using the estimated potential GDP and fiscal balance data. Based on these indices, we 1) analyze how FIs respond to the economic conditions summarized in GDP gap through regression analysis, 2) compare average FIs in expansionary and recessionary periods according to the NSO's economic cycles, 3) evaluate fiscal policy maker's perception of economic conditions and its intention by reviewing the budget proposals. Although regression analysis shows that overall fiscal policy, especially expenditure side, has properly responded to economic conditions, average FIs do not show the significant difference between expansionary and recessionary periods. It is inconclusive whether the fiscal policy timing has been proper. Budget proposals show that actual fiscal policy stance has been sometimes inconsistent with the policy intention, which implies that it is hard to utilize fiscal policy actively to stabilize the economy.

  • Since South Korea has uneven rainfall and deteriorating water quality, it is imperative to create a comprehensive water resources policy and management. This paper is to adopt a win-win policy for upstream-downstream local governments that have been in water rights-related disputer or conflicts in the process of allocating water and maintaining water quality. The Win-Win Policy can be an integrated river-basin approach. We define the win-win policy, introduce the win-win case of Delaware River and Colorado River in the United States, and suggest the win-win policy for Nakdong River in South Korea. Nakdong River is chosen for this paper because it has more serious problems in preserving water quantity and maintaining water quality.

  • The purpose of this study was to analyze the number of university entrants influenced by the population decline of school age, to discuss the major issues of university restructuring policy initiated by government, and to suggest the mid- to long-term policy agenda on university restructuring. According to the analysis of university enrollment changes, university enrollment quota will decrease to 29% of year 2013. And the ratio of private university enrollment and the entrants of universities in the metropolitan areas will increase. Under these circumstances, it is highly concerned that high school graduates will be more concentrated to private universities located in the metropolitan areas. The government policy on university restructuring have several problems on the direction, the pursuing strategies, and the negative impacts of it. This study suggested the new paradigm for the university development and also the alternative strategies such as the balanced development in universities, financial support system, school-to-work policy, university collaboration system, and an enactment of university development.

  • This paper proposes a monetary aggregate "Liquidity" that could serve as a useful indicator for gauging the appropriateness of monetary policy. If liquidity rises above a certain threshold, it is signaling that monetary policy is losing traction due to structural and other impediments even when the inflation gap remains open. This indicator supplements the financial cycle approach but adds value by providing a benchmark that is derived from the national account, and not based on its own trend. Over the last two decades, each time this measure rose above the threshold range, it was followed by a decline in GDP growth. The latter was greater when accompanied by a high physical asset value to GDP, e.g., an elevated property market.

  • Many advanced countries including the U.S. consider defense standardization as a critical task for the efficient acquisition and effective operation of weapon systems and have implemented the appropriate standardization policy by synchronizing the defense acquisition strategies and nation standardization policy with defense standardization. It is required to develop the long-term defense standardization policy that can cope with the future domestic and international defense environmental changes. Therefore, it is an inevitable task to investigate the standardization trends and strategy in the domestic and international perspectives. The study aims to provide the vision of defense standardization policy, act/regulation, organization/personnel, education/training and information system.
