There have always been dilemmas between development and environmental conservation throughout the world. Gradually environmental contamination threatens sustainable development and conservation. we try to study on the sustainable development with environmental conservation. One of the instruments to get this goal is Environmental Impact Statement. Environmental Impact Statement has now become a standard tool of decision making in Environmentally Sound and Sustainable Development. The objectives of this study is to explore and suggest some suggestions for improvements of EIA. 1. Identify all criteria and standards that apply to physical and social environmental components and dynamics. 2. Giving attention to the purpose of the criterion and standard, with respect to resource use and quality. 3. Demonstrate the relevance legal, technical, and scientific authority by early planning through construction, operation and maintenance phases. 4. Implement rationales and protocols for the documentation of standard analytical methods, location of sampling points and statistical analysis of data. 5. Establish precise protocols by predictions of environmental impact relevant for established criteria and standards. Reviewing these protocols with relevant legal authorities prior to their implementation is important.

The underground living spaces have become one of the major environment of this decade in urban area. This study was carried out to examine contamination level for purpose of preservation of the pleasant underground environment. Three subway stations and three underground shopping centers in Seoul and two underground shopping centers in Busan were selected and surveyed by measuring gaseous pollutants $(SO_2,\; NO_2,\;CO,\;HC,\; HCHO,\;CO_2)$, dust, airborne microbes, and the other air condtions (temperature, humidity, air pressure, air flow, kata cooling power). These examined data were compared with four kinds of standard (building sanitation management, room air quality standards, occupational safety and health standards, ventilation equipment) as environmental hygiene.

This paper introduces determination rules for specifications of quality characteristics and dependability requirements. This study also presents guidelines for various inclusions in standards such as environmental aspects, safety aspects, third-party certification systems, medical devices, and the needs of older persons and persons with disabilities.

This study was carried out to estimate leaching characteristics of incineration residues from municipal solid waste incinerators, and determine organic compounds in raw ash, leaching water and leaching residue. A total of 44 organic compounds, which were analyzed by GC/MSD and identified by wiley library search, were contained in bottom ashes. A total of 17 organic compounds were contained in fly ashes. Bottom ash and fly ash were found to contain a wide range of organic compounds such as aliphatic compounds and aromatic compounds. Organic compounds such as Ethenylbenzene, Benzaldehyde, 1-Phenyl-Ethanone and 1,4-Benzenedicarboxylic acid dimethyl ester were detected in raw ash, leaching water and residues (from bottom ash). Organic compounds such as Naphthalene, Dodecane, 1,2,3,5-Tetrachlorobenzene, Tetradecane, Hexadecane and Pentachlorobenzene were detected in raw ash, leaching water and residues (from fly ash). Through the leaching characteristics of incineration residue, it was represented that the open dumping of incineration residue can contaminate the soil and undergroundwater. In order to prevent environmental contamination that derived from extremely toxic substances in the incineration residues, it is particularly important that the incineration residues should be treated before disposal the incineration residues. Further study and proper management about leaching characteristics of organic compounds might be required.

Korean water quality standards for the protection of agricultural water uses were originally derived based on management of public water resource. They were not prepared to protect crop plants from contaminants, and therefore required water parameters in agricultural uses were excluded in current water quality standards. Korean water standards in river and lake have five levels, and level IV is correspondent to agricultural water uses. Currently, there is no Korean guidelines to protect crop plants from contaminants contained in agricultural water. In Canada, agricultural water guidelines are provided to protect crops from contaminants. In this study, agricultural water quality standards in Korea were compared with them in developed countries to evaluate the adequacy of Korean water quality standards for the protection of agricultural water uses. Additional water quality parameters in agricultural uses were also proposed. Suggested parameters include electric conductivity, sodium, chloride, boron, copper, iron, zinc, and microbiological quality, They are the required parameters to protect crop plants as well as human health. Current water quality standards in agricultural uses was not considered to be appropriate in terms of crop protection. Additional water parameters should be included in agricultural water quality standards.

In this study, the effect of standard phase difference in calibration of carbonyl compounds (CC) was evaluated by using their standards prepared in both gaseous and liquid phase. For this analysis, standards in both phases were prepared for 6 different CCs (formaldehyde (FA), acetaldehyde (AA), propionaldehyde (PA), butyraldehyde (BA), isovaleraldehyde (IA) and valeraldehyde (VA)) at similar concentration levels. Their gaseous standard was calibrated after derivatization with three types of DNPH cartridge, and their calibration results were compared against liquid-phase standards. Although there was a strong compatibility between 2 phases for CCs with lower molecular weights (e.g., formaldehyde and acetaldehyde), it was not the case for the heavier CCs. The results of our analysis indicate that the analytical bias of the heavier CCs can be significantly large (by more than a few tens of %). As a result, underestimation of hevier CCs can be significant, if their gaseous samples are quantified by liquid phase standard.

Purpose: This study aims to analyze and supplement the standards related to healthcare facilities, negative pressure isolation wards, and emergency treatment facilities. In addition, through environmental investigations, analysis of emergency remodeling cases centered on the structural and HVAC characteristics of healthcare facilities is conducted. Methods: Domestic and foreign standards related to healthcare facilities were analyzed. Field investigations and architectural drawing analysis of general and emergency treatment facilities were conducted. Results: Healthcare facilities have different space classifications and air conditioning methods depending on the site situation. Emergency treatment facilities are classified into cases where the HVAC system is remodeled and portable negative pressure unit is installed, and some facilities did not meet the standards for differential pressure and air change rate. Implications: When developing emergency remodeling technology, remodeling and safety evaluation guidelines, it is considered possible to propose clearer guidelines for emergency remodeling treatment facilities for infectious diseases in Korea by referring to the results of this study.
