  • 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.

  • The controversies that have surrounded the negotiation of both the Comprehensive Economic and Trade Agreement (CETA) and the Transatlantic Trade and Investment Partnership (TTIP) have underlined the difficulties arising out from the adoption of a truly common EU investment policy. Non-governmental organizations have called into question transparency and legitimacy of international investment arbitration during the negotiations. The article presents a reflection about current developments of the EU investment policy addressing, in particular, the criticisms towards the whole investor-to-State system and the EU's efforts in developing a "tailor-made" investment agreement and Investor-to-State Dispute resolution system. Along these lines, the article critically assesses the recently announced proposal for the establishment of an 'Investment Court System' put forward by the EU during the TTIP negotiations.

  • This paper explored the public issue on housework analyzed the policy and the law associated housework and developed the theorical model for its political program. This idea is dependent that the policy has priority over change of the social ideology. That policy contains a campaign and a education to be aimed to share of housework in order to make responsibility of men as well as women on family and work. Also it contains economic value estimates to quantify and value the non-wage work(childcaring homemaking etc.) in order to confirm its productive activity. It would assume the lawful form as like a social security or a pension. For example the Family Rights Law Tax Law and Social Security Act have to be reflected on the value of housework and to be secured the social status of provider. After all this work was useful to improve a wage and a social status of all women. As consistent policy and operation associated housework are poor in Korea it is difficult to develop theoric l model on this theme. On the range a political proposal on housework would be bound by family policy(evaluation of housework) and women's labor policy(housework support). So the policy intend to secure a family life to improve welfare of women and to equilibrate the family and the work.

  • This study purposed to analyze problems in utilizing hardware and software invested for elementary and secondary school that were distributed through the education information project so far, and to make plans for substantial operation. In order to identify relevant problems and to draw up plans for substantial operation, this study analyzed relevant previous researches and investigated the current state of the utilization of educational information resources in school through question investigation. In addition, we visited elementary, secondary schools, and governmental departments of relevant personnel and had interviews with the people there. From this, we suggested the substance proposals of the educational information resources operation for elementary and secondary school. Therefore, the substance proposal to the information resource in education that was produced by this study would be useful to establish and execute relevant policy for elementary and secondary schools and governmental departments.

  • In this paper, we propose security management architecture that manages efficiently security systems that are produced by different companies and programmable middleware that can reduce the load of management traffic. The proposed architecture applies programmable networks technology to policy based network management (PBNM). The proposed architecture manages and cooperates various security systems using security policy. Also, the programmable middleware provides convenience of management and reduces the overhead of a policy server by translating security policy into execution command. In addition, using programmable middleware, an administrator can manage various security systems that are produced by different companies. We showed that the programmable middleware could reduce the load of management traffic by comparing processing time for enforcing and transferring of policies/messages between the proposed architecture and PBNM architecture.

  • Content Central Network (CCN) appeared to improve network efficiency by transforming IP-based network into content name-based network structures. Each router performs caching mechanism to improve network efficiency in the CCN. And the cache replacement policy applied to the CCN router is an important factor that determines the overall performance of the CCN. Therefore various studies has been done relating to cache replacement policy of the CCN. In this paper, we proposed a cache replacement policy that improves the limitations of the LFU policy. The proposal algorithm applies real-time producer popularity-based variables. And through experiments, we proved that the proposed policy shows a better cache hit ratio than existing policies.

  • Recently, LVDC(Low Voltage Direct Current) has been came into the newly spotlight with HVDC(High Voltage Direct Current) and as increasing digital load, DC power supply and high quality of demand is also getting extended. In accordance with the report of EPRI(Electric Power Research Institute), they expect digital load will grow to 50% of whole load in 2020. Subsequently, the use of DC equipment will grow dramatically. Therefore, the careful adoption of LVDC standardization policy is urgently required for the safety of people, prevention of confusion and occupancy of the market.
