Automated Storage and Retrieval Systems (AS/RSs) are an important facility for modern material management. The expected benefits of these capital-intensive facilities are gained when their control policies and their physical design parameters are determined simultaneously. In this paper we present several analytical models that capture the impact of the storage assignment policy and of the rack design on the expected storage and retrieval times. Sequential and interleaved service modes are considered for sequencing the storage and retrieval requests. We further investigate the impact of the rack structure on the relative performance of the following storage assignment policies : closest open location (random), full turnover-based policy, and class-based. Our analysis clearly indicates that significant savings in crane travel time are realized when implementing full turnover-based policy, rather than random. These savings become more and more pronounced as the profile of the storage racks approaches the square-in-time shape. Furthermore, it is shown that a class-based policy, with a small number of storage classes, will capture most of these savings and be easier to manage in practice.

In the current Internet system, there are many problems using anonymity of the network communication such as personal information leaks and crimes using the Internet system. This is why TCP/IP protocol used in Internet system does not have the user identification information on the communication data, and it is difficult to supervise the user performing the above acts immediately. As a study for solving the above problem, there is the study of Policy Based Network Management (PBNM). This is the scheme for managing a whole Local Area Network (LAN) through communication control for every user. In this PBNM, two types of schemes exist. As one scheme, we have studied theoretically about the Destination Addressing Control System (DACS) Scheme with affinity with existing internet. By applying this DACS Scheme to Internet system management, we will realize the policy-based Internet system management. In this paper, to realize it, concept of the Internet PBNM Scheme is proposed as the final step.

The purpose of this study was to find ways to impact policies in order to invigorate convergence research as a whole (including science or engineering-based and its humanities-based counterpart), so it can be recognized as the science of its own form. Firstly we looked at the definition of convergence research. Secondly, we looked at the definition of policy and how policies are produced. Lastly, we explored the relationship between convergence research and policy decision making. The current issues faced by the convergence research were the fact that it was largely under-appreciated and inadequately supported both in terms of policy and financial support. In this study, we explore the relationship between research and policy based on a research utilization model, which can be categorized the research and policy relationship into four types. Then we sought for various cases to explore how research can affect policies as scientific evidence; how the technological changes caused by convergence research can be shaped into policies; and then provide insights for what challenges needed to be addressed in order to have a positive impact on the relationship.

This policy alternatives for establishment of rehabilitation health care delivery system for the disabled in the community were developed based on the data of current health status and situations of health care management for disabled persons in Korea. This research was conducted with secondary data analysis for identifying health status and current situations of managing health of disabled persons, and discussed current issues for establishing rehabilitation health care delivery systems in the community. Observing the health status and current situations of managing health of disabled persons, scope and target population of disabled person extended. so prevalence rates increased. and the severity of disability intensified and specified. The summary of issues of health management for disabled persons included; 1) absence of comprehensive and systematic policy in rehabilitation health care systems. 2) absence of consumer based rehabilitation health care facilities and delivery systems that are considered as the characteristics of disabled persons 3) fixed form of projects based on the provider and lack of variety in the programs. Hereafter. to overcome these problems. policy alternatives should 1) establish a comprehensive rehabilitation health care policy for disabled persons. 2) establish comprehensive and specific community based rehabilitation health care delivery systems that can promote preventing disability. providing medical care for disabled persons, establishing rehabilitation management for disabled persons and health care when returning to society. 3) provide training and secure manpower for rehabilitation, but the training case managers who will take the roles as an expert rehabilitation nurse mediators for multidisciplinary team work are needed immediately. and 4) include efficient connection and provision of independent services for welfare rehabilitation service and health care. Conclusively. a community based rehabilitation health care delivery system should be comprehensive policy vision of the government on rehabilitation health care delivery System rehabilitation service has to be constructed systematically under suitable facilities con consumer characteristics and rehabilitation health care policy. By doing this, consumer comprehensive community rehabilitation health care delivery system could be constructed disabled person.

Previous RFID systems exclusively manage the tags and readers for each company in individual manner. Thus, RFID system manager should understand and design specifications such as tag events, data format, and etc, based on individual companies. But it is very difficult to know all statements. To resolve theses problems, there has been conceptual research about policy-based RFID service management model that is not restrained from standards of typical RFID systems, including EPCglobal standard, and ISO/IEC standard. However, previous proposed service management model only aimed event management without including device management. Therefore, in this paper, we propose extended device management policy model for giving shape to the proposed policy-based RFID service management model. If the proposing device management policy model is used for device management, we can integrate control management for heterogeneous middleware, diverse RFID devices, and applications for each company. Moreover, we show that the RFID device management policy is translated and processed as an example using the proposing policy model in real-time RFID system.

The paper establishes a policy classification system in order to classify and evaluate the science and technological innovation policies in Korea. We rebuild an innovation system model based on the national innovation system(NIS) concept. The model consists of human capital infrastructure(HCI), institutional infrastructure(II), technological infrastructure(TI), technology market(TM), industrial organization(IO), and innovation networks(IN). We give these 6 components of the modified system 1-digit number, respectively. Then we build the sub-systems according to these components, classify the policy categories in more detail, and finally complete the 3-digit policy classification table. This policy classification table may be useful in studying the science and technological innovation policy in both theoretical and empirical aspects. For example, the table can be the tool to examine the program portfolio profile(PPP) or to implement the questionary survey on the actual policies.

The purpose of this study is to evaluate policy formation stage of Meister high schools. The study analyzed the differences in the recognition of teachers, students, parents, and vocational education specialists about policy evaluation for policy formation stage of Meister high schools. The conclusions based on the results of the study are as follows: First, in context area the recognition of students showed relatively low level. It reflects that the principle of democracy is needed to the policy formation stage of Meister high schools. The participation of stake holders in the policy formation stage is essential. Second, in input area teachers recognized that the financial resources were sufficient. Vocational education specialists recognized that human resources, such as excellent teachers and Meister teachers, needed to recruited adequately. Third, many policies and institutions need to be established for Meister high schools. The Meister high schools should be selected based on the principle of equity. In the selection process vocational education specialists should be included for the principle of professionalism.

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 concept of a holistic innovation policy is defined in this article, with discussions of what it is, why it is relevant, and how it can be implemented to enhance product innovation. It is shown that the innovation systems approach has diffused rapidly during the latest decades and has completely replaced the linear view in the field of innovation research. The majority of European countries are striving in the direction of developing a more holistic innovation policy. However, it is concluded that the innovation policies in European countries are still dominantly linear despite the fact that holistic policy seems to be the driving vision. Innovation policy is behindhand. Why innovation policy is still linear is also preliminarily discussed. Policymakers attending conferences on innovation are practically always in favor of holistic (systemic, broad-based, comprehensive, etc) innovation policies, have abandoned the linear view by learning from innovation research. The division between "linear" and "holistic" seems to be located within the community where innovation policies are designed and implemented, a community composed of policymakers (administrators/bureaucrats) and elected politicians. Perhaps the dividing line is between these two groups in that politicians, who actually make the decisions, may still reflexively believe in the linear view. Nevertheless, there seems to be a failure in communication between researchers and politicians in the field of innovation and there is therefore a strong need to involve innovation researchers in policy design and implementation to a much higher degree. Another way to increase the degree of holism could be to separate innovation policy from research policy, since their integration tends to cement the linear character of innovation policy. The empirical results are based on a questionnaire sent to twenty-three EU Member States, out of which nineteen (83%) responded. Part of the work for this article was carried out for the European Research and Innovation Area Committee (ERAC) of the European Commission (DG RTD).
