This paper shows construction management focused on waste management in construction project in planning stage Construction waste is given a great deal of weight on total waste. And it is issued in government policy. But it show the limit of problem.As a result of having referenced idea as describe above, this paper will be studied by this process. First, present condition of development waste, cases is researched in construction projects. Second, problems of development pattern and management system are investigated and checked in project cases. Third, maintenance and management method project are proposed by application of planning Stage.

This paper is studied on waste water maintenance management system for Integrated computing environment. This computing environment consist of Waste-Water Maintenance Management and GIS(Geographic Information System). This system can be developed by constructing Database which is set of rules occurring while management work of waste water system is processed. This system will help person who has responsible for making decision. Objective of such computing environment is providing efficient working environment for waste water facility management. Especially we analyzed problems of existing waste water maintenance management. We carried out efficient management of water facility and it will provide solution for major decision making work with low cost using Waste-Water Maintenance Management System

Since the use of plastics in various goods such as film, containers, and packaging has been increasing in Korea, the generation of plastic waste is increasing. Plastic wastes are managed by waste charge system, Extended Producer Responsibility (EPR) system and voluntary agreement of plastic waste collection-recycling system. Recently, the management of plastic waste is becoming a social issues due to the refusal of the collection of plastic waste including waste plastic bag and waste vinyl. The ministry of environment in korea was set up the comprehensive plan for recycling waste management in accordance with the circulation cycle of manufacturing and production - distribution and consumption - separate and discharge - collection and sorting - recycling. In this study, the improvements for management of plastic waste were suggested with the review of domestic waste plastics management and the comprehensive plan by the ministry of environment.

Recently, International Atomic Energy Agency and major leading countries in radioactive waste management tend to subdivide the categories of radioactive waste based upon risk-graded approach. In this context, the category of very low level waste has been newly introduced, or optimized management options for this kind of waste have been pursued in many countries. The application of engineered surface landfill type facilities dedicated to dispose of very low level waste has been gradually expanded, and it was analyzed that their design concept of isolation has been much advanced than those of the old fashioned surface trench-type disposal facilities for low and intermediate level waste, which were usually constructed in 1960's. In addition, the management options for very low level waste in major leading countries are varied depending upon and interfaced with the affecting factors such as: national framework for clearance, legal and practical availability of low and intermediate level waste repository and/or non-nuclear waste landfill, public acceptance toward alternative waste management options, and so forth. In this regard, it was concluded that optimized long-term management options for very low level waste in Korea should be also established in a timely manner through comprehensive review and discussions, in preparation of decommissioning of large nuclear facilities in the future, and be implemented in a systematic manner under the framework of national policy and management plan for radioactive waste management.

The use of food waste disposers (FWDs) can be an emerging option to manage organic food wastes in municipal sewage system. The cost-benefit analysis (CBA) of introducing domestic FDWs is conducted to access the allowable disposer market price and the economic impact on food waste management from conventional solid waste management system. If the convenience value of 10,000 won/month is taken into consideration based on survey results, the introduction of FDWs can lead to net economic benefits, allowing the capital cost of disposer up to 1,000,000 won/unit. Without the consideration of convenience value, the introduction of FWDs becomes profitable if the capital cost of disposer is less than 50,000 won/unit. In case that the value of convenience is more than 7,000 won/month, the reduction of food waste management cost is not valid for the introduction of FWDs to be non-profitable. However, if environmental externalities are considered, the proposed system could become breakeven with the cost of food waste management decreases by 54 % (60,000 won per ton).

The purpose of this study is to analyse whether the waste disposal volume level in the construction waste disposal industry makes a different effect on earnings management behaviour by size of the licensed storage capacity and by location of the waste disposal site. The empirical results of this study are as follows. First, the waste disposal volume significantly influences earnings management behavior. When it comes to the size of licensed storage capacity in the small-sized capacity firms, the smaller waste disposal volume firms make more aggressive earnings management by using discretionary accruals. On the other hand, in the large-sized capacity firms, more waste disposal volume firms report higher earnings by adjusting more discretionary accruals. Second, the effects of waste disposal volume on the earnings management show different pattern depending on the location of waste disposal site. When the firms are located in the non-capital regions, the smaller waste disposal volume firms report higher earnings by adjusting discretionary accruals as well as by using real activities earnings management. However, the firms located in the capital regions show more aggressive earnings management when they have higher waste disposal volume level.

The purpose of this study were to examine the disposal consciousness of foods waste and meal management behavior related to environmental conservation, and to find out the ways to improve the disposal of foods waste. Data were collected from questionaire with 786 housewives who live in Chonbuk area. About 45% of foods waste consisted of vegetables and fruits. The levels of cooking(use) and idsposal behavior among meal management behavior were relatively high, but food preparation(buy) score was low. These results suggested that menu planning before food preparation, and buying some cleaned and trimmed foods in the market should be recommennded to reduce the foods waste. The levels of meal management behavior did not show any significant associaations with disposal consciousness of foods waste but were positively correlated to environmental conciousness. It could be thought that the effort of government administration to reduce and reuse of foods waste is needed to improve the desirable disposal behavior of that, and the well programmed enviornmental education should be more required and practical than increase the environmental conciousness.
