The sea environment must be preserved for maintaining various coastal resources. In order to preserve the sea environment, this study is to find problems in the process of producing photocatalyst materials, which can purify sea pollution, and to develop the heuristic algorithm satisfying those problems. The heuristic algorithm of this paper is developed through constructing the mathematical model and analyzing the mathematical structure of variables and constraints in that model. The algorithm developed in this paper consists of the first process of initializing, the second process of lot combination and the third process of improving solutions. Some experimental results are given to verify the effectiveness of the heuristic algorithm developed in this paper.

Although many local governments are supporting the environment-friendly regional agriculture(hereafter EFRA), the EFRA is not wildly extended since the marketing and consumption of the environment-friendly agricultural products are still limited. This study aims at finding out the new development source of Korean agriculture and strategies for establishing regional agriculture. For these purposes, Sunchon-si cases of EFAP development are introduced and the functions and roles of bodies in charge of regional agriculture are looked over. In order to establish the EFRA, production, processing and consumption needs to be intimately linked all together. As preconditions for developing the EFRA, four points should be satisfied. Firstly, production organizations need to be built and stabilized for developing the EFRA and consumers' organizations and partnership are to be formed. Secondly, the government should support for building consumers' organization. Thirdly, social consensus for developing the EFRA needs to be formed. And finally with the appropriate local and central governmental support the partnership among producers, consumers, and government should be formed.

This research aims to propose a ubiquitous integration monitoring system for the feeding and environment management of livestock production. The integration monitoring system proposed in this research is based on an integrated platform, and consists of livestock shed environment monitoring system, livestock monitoring system, livestock remote medical treatment, and feeding and management system. This research conducts the followings. First, we review the previous researches on livestock related ubiquitous monitoring system to examine the factors to be considered in the proposed system. Then, we design the system and implement the prototype to demonstrate the possibility of the application of this system to real stockbreeding environment.

Purpose: The purpose of this study was to develop and test a structural model on work-related musculoskeletal disorders of women workers. Method: Data were collected from 237 women workers from industries such as electronics, food production and garment production, and analyzed by LISREL 8.54. Result: The fitness indices of the model are GFI=.87, NNFI=.91, PNFI= .74. Eight out of the ten paths were proved to be statistically significant: work environment$\rightarrow$social support, work environment$\rightarrow$health behavior, work environment$\rightarrow$-WMSDs, domestic work$\rightarrow$health behavior, social support$\rightarrow$health behavior, social support$\rightarrow$job satisfaction, health behavior$\rightarrow$job satisfaction, and job satisfaction$\rightarrow$WMSDs. Work environment. social support, health behavior and job satisfaction significantly influenced WRMDs. WRMDs were accounted for 35% by the predictor variables. Conclusion: In conclusion, this study identifies that work environment, social support, health behavior and job satisfaction are important factors affecting WMSDs. Therefore, in order to prevent WRMDs, it is most important to improve both physical work environment for female workers such as appropriate work station and tools fit for them and psychological environment such as less job demand and more decision latitude(worker control).

Quality management has been recognized as an important means to secure business competitiveness for management environment changes and competitiveness reinforcement. An effort of an ISO 9001 certification has thought that it is the best way to practice quality management. This paper checks a quality management situation of manufacturing companies that acquired ISO 9001 certification. Then, this paper investigates whether quality management is actual1y contributing to production performance and proposes proper alternatives for an improvement of production performance.

In this paper, a case study is introduced on the development on a production planning system for the efficient control of work-in-process material flows. A special attention has been given to the prevention of the shortage of the automobile-components at the auto-assembly lines and the dynamic adaptation of the production plan to the continuously changing environment. The expertise of the production planner is analyzed and transformed into the logic of the software developed.
