To improve the diagnosis and prescription for military personnel, it is required to adopt Clinical Decision Support System (CDSS) in armed forces hospitals. The objective of this paper is to suggest a CDSS for armed forces hospitals using semantic web technologies. To this end, we designed military medical ontologies and military medical rules which consist of the various concepts and rules for supporting medical activities. We developed a semantic web-based CDSS to demonstrate the use of the ontologies and rules for treating military patients. We also showed the process of semantic search for the medical records which are created from the semantic web-based CDSS.

This article consists of 3 parts. Part I is multi stakeholder approach on Internet governance system. Part II is analysis of the Korean Internet governance system. In this part, I explain relevant laws in Korea, including Korean Internet Address Resources Act. Part III is my suggestion on Korean Internet governance system using a multi stakeholder approach. First of all, the keyword of the Internet governance system is decision making process: that is, consensus based versus top-down approach. Then who are major players in Internet governance in national level? Government, or Private sectors such as business and civil society. Korean legal system for Internet governance shows a top-down decision making process. Major players are the government (that is, Ministry of Science, ICT and Future Planning) and KISA affiliated with the government. Other players include Internet Address Policy Committee, Korea Internet Governance Alliance, and NGOs. The key statute for Internet governance in Korea is Internet Address Resources Act of 2004. Articles 3 and 5 require the Ministry of Science, ICT and Future Planning to take a proactive role in Internet governance. The government shall consult with the Internet Address Policy Deliberation Committee for Internet governance. Yet this Committee is established under the control of the Ministry of Science, ICT and Future Planning. All members of this Committee are also commissioned or nominated by the Chairman of the Ministry. Meanwhile, there are also non-official organizations, including Sub-committee on Address & Infrastructure of Korea Internet Governance Alliance. I suggest to reform decision making process of Korean Internet governance system based on BOTTOM-UP process for CONSENSUS BASED DECISION. My suggested system includes the following: (1) The government hands over a major role in Internet governance to INDEPENDENT Internet policy organization. And the government participates in such organization as ONE of the players. (2) Nomination of this committee member must be bottom-up process for a genuine multi-stakeholder model including civil society, commercial organization, end-users and experts. (3) The government should establish plan for supporting the private sector's international activity on the long-term basis.

Environmental Product Life Cycle Management is an activity for defining and describing the product, process or activity environmentally. Especially, the main responsibility for the environmental impact of products lies in the design phase of product. Designers cany a heavy responsibility to determine technical, economic and ecological properties of the product. So in order to help designers, structured understanding and application of treating large amount of data and infonnation should be considered. This paper presents a methodological approach for decision supporting to build Product Life Cycle Management system and show a set of database modeling. Additionally, a key issue for databases is the quality of the provided information.

Purpose: The purpose of this study was to explore the experiences of bereavement for main family members who had made and followed DNR decision for their family members. Method: This qualitative study was based on a grounded theory, and used in-depth interview techniques with the bereaved 10 main family members who had been treated and died under DNR order. Results: The causal condition of the family member was 'Releasing', and the main consequent phenomenon were 'Blaming self and ruminating'. The contextual condition was 'The memory of the deceased'. The action/reaction strategy was 'Purifying'. The intervening condition was 'Supporting system', and the consequence was 'Acceptance'. The experience after bereavement of the family member on DNR decision were rational processes that purified themselves and healed the guilt feeling about the decision from reflective assessment and response about DNR decision. Based on this results, the substantive theory 'Reflective self healing' was derived. Conclusion: The main family members in following DNR decision are more likely to have unhealthy emotional condition than others in normal bereavement process. But they overcame the grief of bereavement through reflective self healing process.

PMS (Pavement Management System) of National highways in Korea has used HDM (Highway Development and Management)-4 developed by World Bank for decision-making for maintenance and rehabilitation of pavements. However using HDM-4 is not appropriate in Korea because HDM-4 requires excessive input factors for analysis and economic analysis models loaded in HDM-4 are not suitable for Korean circumstances. Thus this study aims development of decision-making system for effective pavement management with reflecting Korean circumstances. Moreover this study proposed to define component of system, deterioration models, and basic units for component, and to analyze characteristics of component of system, and also to develop optimal decision-making system. The decision-making system for PMS mainly consists of 1) DB of highways, traffics, and socio-economic index, 2) pavement deterioration model, 3) speed prediction models by pavement conditions, 4) economic evaluation models, and 5) decision-making supporting system. Also this study provided analysis results in case studies for system verifications. However pavement deterioration models considering future probabilistic characteristic and index of decision-making are needed to develop for a further study.

A rotor system is composed of a rotating shaft with supporting bearings. The rotor system is widely used in every rotating machinery such as the turbine generator and the high precision machine tools. A negligible error or malfunction in the rotor, however, can cause a catastrophic failure in the system then result in the environmental and economic disasters. A diagnosis of the rotor system is important in preventing these kinds of failures and disasters. Up to now, many researchers have devoted in the development of diagnosing tools for the system. The basic principles behind the tools are to retrieve the data through the sensors for a specific state of the system and then to identify the specific state through the heuristic methods such as neural network, fuzzy logic, and decision matrix. The proper usage of the heuristic methods will enhance the performance of the diagnostic procedure when together used with the statistical signal processing. In this paper, the methodologies in using the above 3 heuristic methods for the diagnostics of the rotor system are established and also tested and validated for the data retrieved from the rolling element bearing and journal bearing supported system.

It is generally blown that foster children often have special needs such as disability and psycho-behavioral problems. It is also known that foster parents will provide better care with those children when they are coping well with foster children with special needs. The purpose of the study was to explore the perceptions foster parents have and what factors affect their decisions to care for children with special needs. Literature review reveals that successful foster parent care is related to the foster parents' motivation, role perception, and social support systems. foster parents' motivation is related to 'altruism toward foster child', 'the egocentrism of the foster parent', 'previous experience with adoption' and 'the past experiences of the foster parent'. Role perceptions of the foster parent consist of 'supporting the internal system of the foster child' and 'supporting the external system of the foster child'. The social support system is characterized as the limited notions of a family oriented concept. In addition, a foster parent's decision to look after special-needs children is related to their motivation while the decision to foster disabled children is related to the levels of available social support systems as well as motivation. The results of the study implies that the motivation level and that of social support system are closely related to different aspects of the special-needs foster child; this factor should also be considered when recruiting foster parents or placing special needs children.

For the accomplishment of satellite's own missions, complicated control procedures and commands are required. Although absolute-Time Command and Command Sequences have been applied for controlling satellite and its operation historically, these command system only has a capability to manage sequential control process and has a limitation that cannot deal with decision and branch for corresponding to the condition of the time. To resolve above limitation, KARI has designed RTCSC which is mainly based on the existing RTCS but adopts a one-byte Op Code for supporting decision making and conditional branch. This paper introduces the design and implementation of RTCSC as On-Board Control System like OBCP, VML and IP.

This paper presents a dynamic development of an ontology-based statistical information system supporting the collection, storage, processing, analysis, and the presentation of statistical knowledge at the national scale. To accomplish this, we propose a data mining technique to dynamically collect data relating to citizens from publicly available data sources; the collected data will then be structured, classified, categorized, and integrated into an ontology. Moreover, an intelligent platform is proposed in order to generate quantitative and qualitative statistical information based on the knowledge stored in the ontology. The main aims of our proposed system are to digitize administrative tasks and to provide reliable statistical information to governmental, economic, and social actors. The authorities will use the ontology-based statistical information system for strategic decision-making as it easily collects, produces, analyzes, and provides both quantitative and qualitative knowledge that will help to improve the administration and management of national political, social, and economic life.

Schools are one of favorable public buildings for Renewable Energy(RE) systems due to site conditions and their energy demand profiles(e.g. daytime-based use of hot water and heating/cooling). Although the government encourages schools to be equipped with RE systems, the adoption of RE systems in existing energy supply systems faces technical and financial barriers. For example, when installing a RE-based combination system(RECS) to meet the energy demand at various school scales, identifying cost effective combination of capacities of the RECS is not trivial since it usually requires technically intensive work including detailed simulation and demand/supply analysis with extensive data. This kind of simulation-based approaches is hardly implementable in practice. To address this, a simpler and applicable decision-supporting method is suggested in this study. This paper presents a simplified model in support of decision-making for optimal capacities of RECS within given budget scales and schools sizes. The proposed model was derived from detailed simulation results and statistical data. Using this model, the optimal capacities of RECS can be induced from the number of classes in a school.
