There are 3 kinds of forest managements: One of them is forest utilization management which collects abundant forest resources by felling the trees: the second of them is scientific forest management which cultivates forest resources; and the last one is emergency aid forest management, needed by the forest resources davastation, for the surposes of soil conservation and preventing the indirect damages. During the 36 years of Japanese occupation, they pillaged 600 to 800 million cubic meters of the forest resources, in the condition of the colonial system. After the emancipation from the Japanese occupation, the national soil conservation work has been practiced for 18 years without correcting the Japanese forest management (which means felling system); therefore the essential in the forest, conservation works is to get rid of imitating the Japanese pillage management so as to turn the direction of the forestry policy to the emergency aid management which means forest investment.

An integrated water environment management system is necessary in improving water quality, properly allocating water resources, and supporting socio-economic development. Specifically, water quality management system using web map can be an efficient approach to accomplish this system. This paper aims to construct a dynamic water quality management system to reflect a water environment management system which includes three sub-models with consideration of their interrelationships (a socio-economic model based on dynamic Input-Output model, a water resources cycle model, and a water pollutants flow model). Based on simulation, the model can precisely estimate trends of water utilization, water quality, and economic development under certain management targets, and propose an optimal plan. This study utilized the model to analyze the potential of using reclaimed water to accomplish local water environment management and sustainable development plan while exploring the applicable approaches. This study indicates that the constructed water environment management system can be effective and easily adopted to assess water resources and environment while improving the trade-off between economic and environment development, as well as formulate regional development plan.

Traditional cost system is distorted due to the using unit-based measure. It is being criticized that it do a poor job of attributing the expenses of support resources to the production and sales of individual product. Activity Based Cost System expend the range of second-stage cost assignment drivers beyond the traditional measures of labor and machine times, units produced, and material quantities to allow for drivers that measure the amount of batch-level, product-sustaining, and facility-sustaining activities performed. It is a resources consumption model of organization, not just a more complex cost accounting of cost allocation system. This paper proposes a enterprise resource planning by activity based management. To effective performance system for company that want to be setting competitive levels, the information systems must support a fast moving, rapidly changing. Activity based management is a process of accumulating and tracing cost and performance da to a firm's activities and providing feedback of actual results against the planned cost to initiate corrective action where required. Therefore this system provides a highly powerful decision-making tool. To construct this system, we need Enterprise Resource Planning System. Since ERP is designed around the idea that rapid change and a degree of unhandled change is normal, it allows driving the customer's rapidly needs much deeper through the business cycle.

Recently drastic climate changes(e.g., extreme floods and droughts) are often taking place around the world. Even an increase in uncertainty, population, and mega cities has caused drastic changes in water recycle process. As in other countries, Korea has faced some issues relevant to water security. In response to these changes, Smart Water Grid(SWG) system combining the current water resources management with ICT (Information and Communications Technology) is considered as a new paradigm for the Korean water resources management. This study aims to explore and identify influential factors contributing to the SWG system's application to analyze the importance and role of those factors, and then to offer a policy suggestion for the successful application of the SWG system along with legislative improvements in Korea. In this study, we looked at different barriers related to the SWG application and also the complicated Korean water laws, enacted by different ministries and in order to efficiently apply the SWG system to the current Korean water resources management structures. This study employed qualitative research methods to analyze and identify the priorities of the tasks to be implemented by analyzing conditions for the SWG application, especially related to multi water sources and micro water grid, because legal and institutional measures can be more important to manage conflicts between different stakeholders once the SWG enters a phase of standardization and commercialization from its development stage.

Workflow management system provides automation of job processes by maintaining shareability on information about various job process schedules and persons related to those schedules. Existing workflow management systems use file or database to store the information generated in those systems. However, file or database system could manage only non-complicated information for the workflow but not the information resources of an enterprise which is complicated and of various formats. Therefore, we need a data management system that could control those information resources. This system should manage the data which are distributed at several places geographically. Information Repository could meet those requirements. Information Repository may integrate, store and manage information resources requested by application systems. We have an international standard for the information repository, Information Resources Dictionary System(IRDS). The IRDS, however, does not support distributed environment. In this paper, we design and implement an information repository based on IRDS that may be operated in distributed environment. We verify that this information repository is more effective and is more effective than any other file or database system.
