The increase in hazard level is attributed to the industrial hazard environment; complete national environmental hazards to human health include climate change. The damage level in Korea from 1993 to 2009 has exceeded the Increase In adverse environmental conditions. Priority areas of concern will include those risks that are most likely to occur and are expensive when they do take place such as accident or injury at a community pool. Therefore, in this paper, we suggest the System Engineering method for application to the railway RAMS. Recently, the requirement of high-integrity level of infrastructure has been deemed important. The systems level approach is defined through the assessment of the RAMS interactions between elements of complex system applications.

Recently It becomes a rapidly growing concern to find effective ways of managing IS development projects as the projects increase in many organization. This paper focuses on developing an integrative management framework for IS development project in contingent perspective. The framework is based upon contingent relationship between management dimensions of IS development project and the characteristics of the task replaced or supported by an IS. Management dimensions of IS development consist of mode, content and process. Task characteristics which are considered as contingent variables include project size, unstructuredness level, hierarchical level, interdependence level and system innovativeness level. The data used for validating this conceptual framework are collected from 119 IS development projects in 70 Korean business organizations. One-way ANOVA and T-test are employed to test the hypotheses.

This paper presents a new evolutionary algorithm to solve complex multi-level integration problems, which is called multi-level symbiotic evolutionary algorithm (MEA). The MEA uses an efficient feedback mechanism to flow evolution information between and within levels, to enhance parallel search capability, and to improve convergence speed and population diversity. To show the MEA's applicability, It is applied to the integrated planning of production and distribution in supply chain management. The encoding and decoding methods are devised for the integrated problem. A set of experiments has been carried out, and the results are reported. The superiority of the algorithm's performance is demonstrated through experiments.

Purpose: This paper studies the influence of the case-management program on the change of blood sugar, lifestyle, and knowledge level of diabetes mellitus (DM) for medium-sized-enterprise employees suffering from DM. Method: Subjects, divided into experimental and control groups, are 59 workers with FBS higher than 126mg/$d{\ell}$ or under DM medication treatment in the medium-sized enterprises, being managed by two distinct university hospital group occupational health management service teams. The case management program for DM patients consists of 6 different processes in which each subject is treated. Result: FBS decreased in the experimental group after the program, while that of the control group increased significantly. In the experimental group, the amount of smoking, the frequency of drinking and the amount of drinking per week decreased. Also, the knowledge level for DM and the change of nutrition management showed significant increase. In the control group, the amount of smoking increased and the frequency of drinking, the amount of drinking and nutrition level did not change significantly. And the knowledge level for DM decreased. Conclusion: We expect that taking this case management program for DM management may significantly improve diabetic patients' overall health.

Construction system modeling can enhance work performance by following the behaviors of a system. System behaviors may originate from physical aspects of a system, namely operation level variables, or from non-physical aspects of a system known as context level variables. However, construction system modelers usually focus on only one type of system variable (i.e., operation level or context level) which can lead to less accurate results. Hybrid modeling with System Dynamics (SD) and Discrete Event Simulation (DES) is one of the approaches that has been utilized to address this issue. In this research, an SD-DES hybrid model of a steel fabrication shop is developed, and the benefits of capturing context level variables together with operation level variables in the model are discussed.

Recently, the importance of research and development for technological innovation is increasing. The rapid development of research and development has a number of positive effects, but at the same time there are also negative effects that accelerate crimes of information and technology leakage. In this study, a research security level measurement model was developed that can safely protect the R&D environment conducted at the organizational level in order to prepare for the increasingly serious R&D result leakage accident. First, by analyzing and synthesizing security policies related to domestic and overseas R&D, 10 research security level evaluation items (Research Security Promotion System, Research Facility and Equipment Security, Electronic Information Security, Major Research Information Security Management, Research Note Security Management, Patent/Intellectual Property Security Management, Technology Commercialization Security Management, Internal Researcher Security Management, Authorized Third Party Researcher Security Management, External Researcher Security Management) were derived through expert interviews. Next, the research security level evaluation model was designed so that the derived research security level evaluation items can be applied to the organization's research and development environment from a multidimensional perspective. Finally, the validity of the model was verified, and the level of research security was evaluated by applying a pilot target to the organizations that actually conduct R&D. The research security level evaluation model developed in this study is expected to be useful for appropriately measuring the security level of organizations and projects that are actually conducting R&D. It is believed that it will be helpful in establishing a research security system and preparing security management measures. In addition, it is expected that stable and effective results of R&D investments can be achieved by safely carrying out R&D at the project level as well as improving the security of the organization performing R&D.

The purposes of this study were to compare, through a factor analysis, the perceived level of importance of 4 categories of features relating to food service management between salespeople and clients, to establish an effective marketing strategy for successful contracting. To obtain data on the perceived level of importance level of the factors affecting foodservice management contracts, questionnaires were developed using the Delphi technique, which were modified by apilot test. The questionnaires consisted of 4 categories and 19 items on the factors affecting foodservice management contracts, with the importance level of these factors measured on a 5 point-Likert type scale. Between March 12 and April 13 2003, the self-administrative questionnaires were mailed to the 60 salespeople and 280 clients. A total of 50 clients (25%) and 48 salespeople(77%) responded to the questionnaires. As a result, forprivate contracts and in competitive biding, the differences of the perceived importance level between the salespeople and clients of the 3 categories (the appropriateness of foodservice operation plan, sales ability, the conditions and costs of the contract) were significant. For the 5 items relating to private contracts, Field trip, Menu Management Plan, Sanitation and Safety Management, Cost per meal and Food Cost per meal, both the salespeople and clients perceived high levels of importance for all these items. For competitive biding, both the salespeople and clients perceived high levels of importance for the 6 item the Foodservice operation supportive system, Field trip, Menu Management Plan, Renewal plans for interior and environment, Cost per meal and Food Cost per meal.

Because bridges can cause more significant damage than other infrastructure a certain level of safety shall necessarily be secured for users. As most of bridges' service life become 20-30 years there will be a dramatic increase in the maintenance and repair cost but the budget and human resource will be limited. Asset management technique can help the efficiency in maintenance and budget management with the limited resource. For its application, there must be a way to evaluate how bridges provide service to users. The level of service can be quantified by a performance measure. This study introduces performance measures and an evaluation process for the determination of level of service. The evaluation results will be used as a fundamental information in the determination of maintenance/repair/management targets and in the decision making process of the bridge asset management.
