This paper proposes a policy adjuster-driven Grid workflow management system for collaborative healthcare platform, which supports collaborative heart disease diagnosis applications. To select policies according to service level agreement of users and dynamic resource status, we devised a policy adjuster to handle workflow management polices and resource management policies using policy decision scheme. We implemented this new architecture with workflow management functions based on policy quorum based resource management system for providing poincare geometrycharacterized ECG analysis and virtual heart simulation service. To evaluate our proposed system, we executed a heart disease identification application in our system and compared the performance to that of the general workflow system and PQRM system under different types of SLA.

The Korean Academy of Health Policy and Management (KAHPM) has shown remarkable achievements in the field of health policy and management in Korea for the last 30 years. The KAHPM consists of experts in various fields of health policy and management, and has been the leading academic discussion forum for health policy agendas of interest to the public. Health Policy and Management (HPM), the official journal of the KAHPM, published the first issue of volume 1 in October, 1991 and is publishing the second issue of volume 28 as of 2018. Currently, it is one of Korea' main journals in the field of health policy and management. HPM has published a special issue in commemoration of the 30th anniversary of the KAHPM. The HPM invited authors, including former presidents of the KAHPM and current board members, to write about main issues in health policy and management. Although the HPM tried to set up an invited author on all subjects in the health policy and management field, 19 papers are published, that completed the peer review process by August, 2018. The authors of the special issue of the 30th anniversary of the KAHPM include six former presidents, a senior professor, and 12 board members. The subjects of this issue are reform of the healthcare delivery system, health insurance and medical policy, reform of health system governance, the role of National Health Insurance Service (NHIS), the Korea Institute for Health and Social Affairs (KIHASA) and the National Evidence-based healthcare Collaborating Agency (NECA), ethical aspects of health policy change, regional disparities of healthcare, healthcare accreditation, new healthcare technology evaluation system, globalization of the healthcare industry, the epidemiological investigator system, the quarantine system, safety and disaster, and official development assistance. There are some remaining topics to deal with for the KAHPM: aged society, anti-smoking, non-infectious disease, suicide, healthcare resources, emergency medical care, out-of-pocket money, medical fee payment system, medical aid system, long-term care insurance, industrial accident compensation insurance, community-centered health welfare system, and central government and local government of health. The HPM will continue to publish review articles on the main topics in health policy and management. This is because the KAHPM, which has been the leading academic society of Korea's health policy and management for the last 30 years, feels responsible for continuing its mission for the next 30 years.

In 1987, The Brundtland Report defined a sustainable development as the development that meets the needs of the present without compromising the ability of future generations to meet their own needs. This is the concept that we should cling to, to preserve natural resources of the present for the future generation. With this concept in mind, this paper criticized the current waste management policy has been neglecting resource preservation aspect of waste management policy while giving too much emphasis on reducing waste generation. Thus, the purpose of this paper is to analyze how waste management policy can affect preservation of natural resources, and to investigate policy alternatives that can reduce both the volume of wast geverated and the amount of natural resources that need to be consumed in the production process. The study was conducted based on the literature survey and system dynamics simulation. Borrowing Randers and Meadows's solid waste model with some modification of parameter and variables, this paper simulate several policy alternatives to figure out the most effective waste management policy set that can meet the need of the present without compromising the ability of the future generation to meet their own needs. Main concern was how to link waste management policy with resource management policy that can lead to minimization of waste generation and resource consumption.

In the Internet, an identity service must to obtain permission from a user to allow them to share data with requesting service. For that, the privacy policy, which reflects legal regulations and preferences made by the user, is needed. Also, the management interface that aids the user to make the privacy policy and the PDP system that makes admission control and policy decisions in response to a request from an entity wanting to access the personal information are needed. In this paper, the privacy controller system model handled under the internet Identity management system environment is proposed. The system has the easy interface of policy generation and the efficient policy decision process. The system applies and modifies to the XACML of OASIS group. We propose that the privacy policy is divided into the three policies, which are the user policy, the domain policy and the basic offering policy. To resolve the collision between the policies, we also propose the collision resolution policy.

The purpose of this study is to analyze the school autonomy policy based on the system thinking perspective using causal loop diagrams. School autonomy was the main educational policy concerning school domain during the last government and was the instrument for school-based management, but it was not implemented effectively in site. The school autonomy policy practically disappeared as an explicit policy agenda in the current government. This study displays causal loop diagrams about the policy's logic and contents of school autonomy, in terms of curriculum, human resource management, and a supportive system. The causal loop diagrams depicting the implementation of the school autonomy policy are suggested concerning excessive enforcement and the confirmative mechanism for policy implementation. The conclusion provides some research implications and future directions.

In this paper we have proposed policy-based network management system architecture for Internet QoS support Mobile IP networks that is divided into four layers(application layer, information management layer, policy control layer, device layer), then we propose an implementation strategy of policy-based network management system to enforce various control and network management operations and a model of policy server using SCOPS(Simple Common Open Policy Service) protocol that is developed in this research. For policy-based mobile IP network management system implementation, we have derived four policy classes(access control, mobile IP operation, QoS control, and network monitoring) and we showed operation procedures for each policy scenarios. Finally we have implemented Internet QoS support policy-based mobile IP network testbed and management system and verified out DiffServ policy enforcement behaviors for a target class service that is arranged a specific bandwidth on network congestion conditions.

Most recently, development and publication of the ordinance and the manual of policy quality management is spreading the recognition of quality control in the public sector. The purpose of this study is to introduce the system of quality control for local government's policy. So we suggested lessons drew from the case study(Daegu metropolitan city, Gumi city) on current introduction. To successfully introduce the system of quality control for local government, we have to gain agrement for the new system, of introduction, secondly prepare the new system, lastly manage PQM with flexibility.

An inspection-maintenance policy is investigated for a system having various states. A policy is characterized by the type of maintenance and the next inspection time. Maintenance actions are classified into various types according to the depth of maintenance. Policy evaluation criterion is the expected cost accumulated up to the failure of the system. The problem is formulated as a Markov decision process and an optimal policy is found by using a policy improvement procedure. A numerical example illustrates the policy for a system having five states.

As network systems are developed rapidly and network architectures are more complex than before, it needs to use PBNM(Policy-Based Network Management) in network system. Generally, architecture of the PBNM consists of two hierarchical layers: management layer and enforcement layer. A security policy server in the management layer should be able to generate new policy, delete, update the existing policy and decide the policy when security policy is requested. And the security policy server should be able to analyze and manage the alert messages received from Policy enforcement system in the enforcement layer for the available information. In this paper, we propose an alert analyzer using data mining. First, in the framework of the policy-based network security management, we design and implement an alert analyzes that analyzes alert data stored in DBMS. The alert analyzer is a helpful system to manage the fault users or hosts. Second, we implement a data mining system for analyzing alert data. The implemented mining system can support alert analyzer and the high level analyzer efficiently for the security policy management. Finally, the proposed system is evaluated with performance parameter, and is able to find out new alert sequences and similar alert patterns.

By means of the model competition, this research analyzed the factor of patient management, the factor of policy support, and the factor of medical treatment system. Concretely, the factor of policy support forms a positive effects on the factor of medical treatment system. Practically, well-established healthcare policy provide and facilitate the effective medical treatment system. of the hospital. And, in the effective medical treatment system, hospitals try to develop the patient management of the chronic disease. From the empirical research, this paper concluded that the factor of medical treatment system. mediated by the factor of policy support. Also, the factor of medical treatment system promotes the development of patient management in the chronic disease.
