  • The current enforcement regulation of "Construction Technology Management Act" prescribes calculation standard of environmental preservation cost in construction site. According to this standard, environmental preservation cost is calculated by using the quantity-per-unit costing method or applied fixed rate on direct cost. However, when calculated by using the quantity-per-unit costing method it is few items to put in the budget according to standard of construction estimate and in the case of using the fixed rate on direct cost it is not considering various characteristics of the construction site. Therefore, it is needed a improvement plan of estimating method and management system for environmental preservation cost. In this study, it surveyed the actual state of the environmental preservation cost according to magnitude of project, site location, anti-pollution facilities and etc. over 38 road projects. The research reported in this paper environmental preservation cost was variously distributed over construction sites. Thus it needs to estimating method and management system to consider characteristics of construction site for environmental preservation cost.

  • Despite its usability, TCE has been managed as a hazardous material due to the toxicity and many contamination cases were surveyed in some developed countries. U.S.EPA(Kram et al., 2001) suggested DNAPL characterization methods and approaches based on survey experiences at several sites. However, Korea has not the least assessment of contamination and trial of remediation, although there are a lot of doubtable areas where ground water would be contaminated with TCE. In this study, we try to assess the volume and extent of ground water contamination with TCE and delineate the contamination source zones in an industrial area. Ground water in this area flows through fractures and the contaminant TCE has the properties of high volatility, high density and low partitioning to soil material. Thus, we applied a variety of technical approaches to identify the contamination status; documentary, hydrogeochemical, hydrogeological and geological surveys. In addition, additional survey was performed based on the interim findings, which showed that ground water contamination was limited to the relatively small area with high concentrations to the deep place. The contamination source zone is estimated to be the asphalt test institute where a great deal of TCE has been used to analyze the amount of asphalt soluble in TCE since 1984. Based on the contamination characterization and a myriad of documents about ground water remediation, appropriate site remediation management options will be recommended later. This study is now under way and this paper was focused on describing the technical approaches used to achieve the goals of this study.

  • The Ministry of Environment established a plan for advancement of livestock manure management in July 2011 and finalized the "Comprehensive Measures for Advancement of Livestock Manure Management" in May 2012 complementing and strengthening the plan. In this process, it was necessary to investigate the status of discharge of livestock manure and its environmental impact, for example on rivers, groundwater, arable outflow water and soil. We investigated types of livestock husbandry, discharge of livestock manure, and production and use of organic fertilizers and presented the improvement measures of livestock manure management and organic fertilizer use. First, it is necessary to come up with measures to calculate appropriate density and numbers of livestock animals and prevent overcrowded breeding. Second, as many of the private livestock manure treatment facilities are out-dated and their long-term aerated reaction tanks are not regularly managed, it is necessary to find ways to improve those facilities through inspection and diagnosis. In addition, since existing public treatment facilities are designed to add clean water to belt filter press, additional water is needed. Therefore, it is necessary to improve belt filter press in order to decrease the extra water. Finally, although large-scale organic fertilizer plants and resources recycling centers produce good organic (liquid) fertilizers with proper components, it is necessary to establish standards for maturity of liquid fertilizers in order to facilitate efforts to turn livestock manure into resources.

  • Non-point source pollution management is one of the most important issues in Korean water quality/watershed management. In recent years, Low Impact Development (LID) has emerged as an effective approach to control stormwater in an urban area. This study illustrates how to design and evaluate the effect of non-point pollutant management using EPA-SWMM LID module and suggests design parameters for modeling LID facilities. In addition, optimal installation locations of LID can be determined by a simple distributed hydrologic model by using SWMM for a long-term.

  • In all activities of companies, manufacturing processes are one of those which have the worst effect on our environment. So manufacturing companies have taken the necessary steps to comply with environmental regulations. But, most of them focused on the environmental standard control equipments, using ‘end-of-pipe techniques’ that can obtain the desired reductions in a short time-period. But these methods are essentially symptomatic treatments and are not enough for sustainable development. 3M's solution is the ‘cleaner techniques’which emphasize prevention rather than corrective control. This paper examines the concept of cleaner techniques and the environmental management system of 3M - how to conduct technological innovation to prevent generation of pollution and waste at the source under the 3P program.

  • Electronic Data Interchange (EDI) is an important part of interorganizational electronic commerce due to the strategic impact derived from its use. In order to ensure successful implementation of EDI, EDI controls must first be developed. Because they are implemented in an environmental context, the characteristics of organizational environments have a significant impact on EDI controls. The control strategy for the EDI system - formal, informal, and automated controls - should fit certain organizational environments. A research model has been developed to depict the moderating effects of six environmental variables including industry, organizational, and task characteristics on the relationships between controls and implementation. It is shown empirically that the relationships between EDI controls and implementation are indeed affected by these factors. The results can help management design formal, informal, and automated controls in view of their own environmental contexts.

  • 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.

  • Pasig River is an important river in the Metro Manila, Philippines, since it provides food, livelihood and transport to its residents, and connects two major water bodies; Laguna de Bay and Manila Bay. However, it is now considered to be the toilet bowl of Metro Manila due to the large amount of wastes dumped into the river. Even with the efforts of the government to revive the quality of the Pasig River and its tributaries, it continues to deteriorate over time. This paper provides an overview of the current condition of the Pasig River. The existing water management policies were reviewed, and the issues and challenges hindering the improvement of its water quality identified. Moreover, the water qualities of the rivers in Metro Manila were compared to those of the major rivers in South Korea. The current watershed management system practiced by South Korea has been discussed to serve as a guideline for future recovery of the water quality of the rivers in the Philippines.
