The purpose of this study is to develop a framework for evaluating security levels in hospitals. We classify security indicators into administrative, technical and physical safeguards. The security evaluation model for hospital information systems was applied to three general hospitals. The analysis of the results showed a low security level in information systems. In particular, requirements for administrative and physical safeguards were very low. Hospitals need strict security policies more than other organizations because their information systems contain patients' highly confidential data. The evaluation model developed in this study can be used for guidelines and as a checklist for hospitals. The security evaluation in hospital informational systems needs to be an essential element of hospital evaluation.

This paper aims at identifying the strategies for strengthening regional innovation systems. This paper is based on the objective evaluation on regional innovation systems by regional government officials who are in charge S&T promotion. This paper has two significances. First, regional government officials as manager on S&T policies, will be able to diagnose exactly their own regional innovation systems. Second, we will be able to get a complete figure on regional S&T culture throughout them. This paper argues that, in order to strengthen regional innovation systems, we must reinforce firms' technological capabilities, create and decentralize public research institutes, and diffuse the culture for appreciating S&T and innovation within region etc.

The information system fields of spatial applications have rapidly grown during the last decade in Korea. Spatial data has been produced for a variety of systems without common standards until national GIS Committee defined the data exchange formats among spatial databases in the middle of 1990's. It aimed at promoting data sharing between the different systems in similar application fields. However, a considerable number of databases built prior to the introduction of the standards are not yet standard compliant but still play the roles of the main producers/consumers in the data collection field such as early developed huge AM/FM systems maintained by governmental organizations. The strong autonomy of these databases keeps their own data models, formats and descriptions from being standardized, which leads the sharing to a more difficult stage. Sharing is another way of data acquisition with least efforts and time away from direct collection. A data clearinghouse is the core module which directs users to the relevant data resources. The contents of datasets should be described with predefined metadata standards for precise indexing. Moreover, a number of technical problems have to be resolved for the common use of data between heterogeneous spatial database systems. However, the technical issues can be covered by the present information technologies. The difficulties persist in the political/institutional issues. Institutional issues are derived from the diverse sources such as political background, governmental policies, related laws and/or regulations. The paper will firstly make an analysis of current situation in terms of Korean policies, laws and regulations, secondly abstract the institutional issues from the situation analysis, lastly present guidelines for promoting spatial data sharing in Korea.

Transport sector takes charge of about 20 percent of energy consumption and GHG(Green House Gas) emission in Korea. One of the efficient strategy of reducing GHG is introducing CDM(Clean Development Mechanism), which is one of GHG reduction systems in Kyoto Protocol. Nowadays many tries have done to regist transport policies as CDM in transport sector, however, a lot of things should be investigated to regist CDM in advance. The aim of this paper is assessment of CDM possibility in transport sector. First of all, we review steps and criteria to CDM registration, and select 4 CDM possibility assessment index in transport sector: as follows additionality, methodology, emission calculation, and monitoring. Also, we analyze registed projects and methodologies in transport sector. To assess CDM possibility in transport sector, quantitative and qualitative assessments are carried out in this study. 18 transport policies are categorized as 4 groups and possibility of 18 transport policies are examined. Several policies can reduce GHG, however, they are not fit to regist as a CDM. On the contrary many transport policies have possibility to regist. In addition, we have done questionnaire survey, 'fuel change' policies have high possibility to CDM. However transport policies related to haman activity, like as TOD, have lower possibility. As a result, we can find that enough CDM possibility assessment should be carried out before CDM registration in transport sector.

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.

Korea is examining how to coordinate its S&T policies and solidify its position as a leader of infrastructure innovation policy that forms the foundation for many different policies. A number of questions have been raised, such as whether to install a superior coordinating body like the National Science and Technology Council (NSTC) or separate the budget allocation and coordination authority from the budget-planning ministry. Korea has tried using various institutional coordination devices and functions such as reorganizing its administrative ministries based on related functions and installing or reinforcing a superior coordinating body. In line with these discussions, the strengthening of the S&T policy coordination function through the NSTC is currently under review. In order to design an effective S&T coordination system in step with changing political and social demands, it is important to have a clear recognition of the current context as well as the unique institutional characteristics of Korea. This study examines the evolution of Korea's S&T policy coordination systems and analyzes its features.

Data Distribution Service(DDS) provides the communications service programmers need to distribute time-critical data between embedded and/or enterprise devices or nodes. In this paper, I propose efficient methods for transmitting and receiving messages of various characteristics in real-time using DDS middleware. For high-frequency characteristic data, I describe several DDS packet types and various default and extended DDS QoS policies. In particular, the batching method is probably the best solution when considering several performance aspects. For large-capacity characteristic data. I will show a method using extended DDS QoS policies, a segmentation and reassembly method, and transmitting and receiving a large-capacity data with low priority method considering network conditions. Finally, I simulate and compare the result of performance for each methods. This results will help determine efficient methods for transmitting and receiving messages of various characteristics using DDS middleware.

This paper deals with ordering policies of consumable goods which have large demand rates in a multi-level distribution system. The system we are concerned consists of one Central Distribution Center(CDC) and N non-identical Regional Distribution Centers(RDCs) which have different demand rates, minimum fillrates, leadtimes, etc. The customer demand on the RDC is stationary poisson and the RDCs demand on the CDC is superposition of Q-stage Erlang distributions. We approximate the RDCs and CDC demand distribution to nomal in order to enhance the efficiency of algorithm. The relevant costs include a fixed ordering cost and inventory holding cost, and backorder cost. The objective is to find a continuous-review ordering policy that minimizes the expected average costs under constraints of minimum fill rates of RDCs and maximum allowable mean delay of CDC. We developed an algorithm for determining the optimal ordering policies of the CDC and the RDCs. We verified and compared the performance of the algorithm through the simulation using the algorithm result as the input parameters.
