Increasing the need of national safety management system in order to an epoch-making improvement to scientific disaster management which appears new types of disasters through the exchange of traditional disaster environment and responds actively to the rapid exchange of social environment based on u-IT. Requiring the development of systematical information sharing networking system and sharing realtime data amongst government, local authorities and related organisations under both safety management in normal times and circumstance management in disaster times, and need for the establishment of national safety strategy, which has been strengthened function such as prevention and preparation. This research provides a basic scheme and strategic tasks in order to constitute preventing scientific national disaster prevention structure at anytime and anywhere from disaster which is based on ubiquitous technology and realise the intelligent national disaster prevention system of u-safe Korea.

GCM(Green Chain Management) is being spread by that companies which apply with eco-friendly concept in entire SCM(Supply Chain Management) perspective is being increased for resolving some recent environmental problems. There are reasons that numerous companies focus on GCM. At first various governments began to directly manage components and material contents about various noxious substances. Second, environment problem management in the entire logistics process from procurement of product materials to distribution of product became to be important according to introduction of certification system that evaluate the environmental impact throughout life-cycle of products. Purposes of this paper are 1) to analyze the GCM process whose important is more increasing in the recent logistics environment change, 2) to comprehend places and sources that generate environmental elements like energy consumption and greenhouse gas emissions in elements of logistics function, and 3) to construct integrated GCM system for observing activity of logistics function throughout life-cycle of products.

In enterprise environments, file owners are often required to share critical files with other users, with encryption-based file delivery systems used to maintain confidentiality. However, important information might be leaked if the cryptokey used for encryption is exposed. To recover confidentiality, the file owner must then re-encrypt and redistribute the file along with its new encryption key, which requires considerable resources. To address this, we propose a key management server that minimizes the distribution of encryption keys when critical files are compromised, with unique encryption keys assigned for each registered user to access critical files. While providing the targeted functions, the server employs a level of system resources comparable to that of legacy digital rights management. Thus, when implemented in an enterprise environment, the proposed server minimizes cryptokey redistribution while maintaining accessibility to critical files in the event of an information breach.

Today, the management environments of intelligence firm are changing the way of production planning and logistics management, and are changing the process of supply chain management system. This paper shows the development of information system software for intelligence enterprises is used in supply chain management for robot engineering industry. Specifically, supply chain management system in this paper has been developed to analyze the impact of multi plant and multi distribution environment, showing the process analysis and system development of hierarchical assembly manufacturing industry. In this paper we consider a production planning and distribution management system of intelligence firm in the supply chain. We focus on a capacitated production resource and distribution volume allocation problem, develop a mixed integer programming model, and propose an efficient heuristic procedure using a genetic algorithm to solve it efficiently. This method makes it possible for the population to reach the feasible approximate solution easily. The proposed regeneration procedures, which evaluate each infeasible chromosome, makes the solution converge to the feasible approximate solution quickly.

Environment standards can be used as a foundation of environment administration (specific expression of political goals or quantitative evaluation standards of political effects). When environment adminstration improves severe air or water pollution rapidly, the environment standard can work effectively to show the goals specifically and clearly. The environment index which is designed to evaluate environment systems, should be established to express the environment system generally. To realize sustainable development, the sustainable indexes usually consisting of these three areas in that harmony of environment, economy and society are required. In this research, sustainable environmental indicators to understand the characteristics and to compare likes theme of environmental conditions in international and national level indicators, regional environmental management plan to promote the management by objectives are to provide the basic data. It is desirable for the environmental policies to work harmoniously with direct control, use of economic means and voluntary methods. Regarding the evaluation of environmental index, the action results of civilian's or individual's activities are needed to be reflected into the evaluation.

Effective management strategies of railroad environment should be prepared by the systematic management with the environment core technologies from the initial stage of the railroad environment to provide energy-efficient, safe, sound, and environment-friendly railroad service. In addition, the need for the development of railroad environment policy, like the improvement strategies and development strategies of railroad environment, is strongly required to actively prepare for the strengthening of environment regulations and supervision on the railroad environment problems. In this research, we studied the correlations between railroad environment policies and management strategies, and defined the component of environment policies. Moreover, we tried to present the direction of environment policies and mid-/long-term development plans that suit for the characteristics of Korean railroad through investigating the environmental policies of advanced countries.

In the real environment, it is not easy to get the effective training or to simulate several hazard situations for safety because of the direct exposure to the hazards of the actual system. But the virtual environment(VE) can help the users to get the effective training or to simulate all kind of possible situations without the exposure to the harzards of the actual system. Therefore, the number of virtual reality(VR) application for safety will be increased dramatically in the future. This paper proposes a category of VR applications and also the steps to develope the VE for emergency management.

Objectives: The Ministry of Employment and Labor has revised the articles regarding management of the thermal environment in the workplace. Currently, two types of regulations exist together with indoor workplaces as the scope of application. It appears that the time has come to discuss regulations. In this study, we aim to identify the feasibility of and problems with the current system through a comparative legal review of workplace thermal environment management laws from around the world. We suggest directions for improving South Korea's workplace thermal environment management laws. Methods: For the several selected countries, we analyzed the classification and content of obligations stipulated for the thermal environment, the presence or absence of specific measures for thermal environment management, legal status and content, and the scope of application of thermal environment provisions and measures. The investigated content was classified according to Zweigelt-Kotz's legal theory. Results: In some countries, employers' obligations for regulating the thermal environment are broadly divided into two types: results and actions. The scope of application of provisions and measures on the thermal environment was extensive, with most of the selected countries targeting general workplaces. Conclusions: In the case of South Korea, restricting and classifying target workplaces and imposing separate obligations to manage a workplace thermal environment goes against global practices, and stipulating legal orders and separate action obligations in guidelines does not conform to the characteristics of South Korea's legal system, meaning that improvement is needed.
