Introduction of TBELs into Korean environmental regulatory system for wastewater may require very careful considerations and appropriate modifications of the TBELs applied in US. The Korean regulations for wastewater are based on uniform regulatory criteria for wastewater effluent discharge and are quite different from the individual permit system in US. In addition, the toxic pollutants regulated in Korea are much less than those in US. Therefore, the effects of TBELs application on the pollutants reduction and the economic feasibility should be carefully assessed for different categories of wastewater sources. In this study, the applicability of TBELs for the industrial categories of Korea was discussed. The TBELs were derived for a sample category, the pulp paper paperboard manufacture, based on the previously reported analytical data from 52 facilities of the domestic pulp paper paperboard manufacture in Korea. It was suggested that the BAT effluent limitations were BOD 30 mg/L, $COD_{Mn}$ 40 mg/L, SS 40 mg/L, T-N 30 mg/L and T-P 4 mg/L and that the allowable effluent loads were $0.31{\sim}1.75kgCOD_{Mn}/ton$-products. Due to the limitation of insufficient data, there were difficult to obtain the important factors to derive more systematic and accurate limitation standards for the pollutants such as the 'Long Term Average (LTA)', the 'Product Normalized Discharge Flow (PNDF)', and the 'Variability Factor (VF)'. However, as the first trial of TBELs determination based on the all available analytical data reported, the procedure and the outcome of the study may provide valuable insight on application of TBELs in Korea.

In this study, we applied DRASTIC and SINTACS models for the assessment of groundwater vulnerability to Buyeo-eup area in Buyeo-gun, Chungcheongnam-do, Korea. Currently, DRASTIC model is a main tool for the assessment of groundwater vulnerability, which has been widely applied for the multiple purposes related to local developments, construction projects, groundwater investigations, etc. since 1980s. Because DRASTIC model has been the sole tool used for the domestic environment, there has been doubt about the degree of reliability of the model, and a benchmark model has been sought by the many practitioners. The objective of this study is to check the applicability of SINTACS model to domestic environment, which is the first attempt in Korea as far as authors understand. The comparative results show that the DRASTIC assessment underestimates groundwater vulnerability of the aquifers composed of fractured bedrocks while that from the SINTACS model is relatively higher. Through this study, it is expected that SINTACS model serves as a reasonable alternative of DRASTIC model where the subsurface is composed of more than two different media such as fractured rocks and alluvium.

국내의 내화성능평가는 대부분 사양적설계 방법인 품질시험을 통해 이뤄지고 있다. 하지만 시험 특성상 많은 비용과 시간을 요구하며 다양한 건축구조에 대한 내화성능평가에는 어려움이 많다. 따라서 본연구에서는 성능적 설계를 위한 연구로 유한요소 구조해석 프로그램인 ABAQUS를 사용해 H형강 휨재를 대상으로 변수에 따른 열응력 해석을 통해 내화성능을 검토하며, 하중비별 한계온도를 제안한다.

국내 설정에 적합한 차음성능기준 및 등급화 방안을 설정하기 위하여 그 기초 연구단계로서 주민반응조사 및 차음성능수준을 측정하고, 차음성능 평가치와 생활감과의 상관관계를 분석 외국의 기존 평가기준곡선 적응가능성을 검토하였다. 분석결과 ISO에 의한 평가방법보다는 JIS에 의한 평가방법이 국내 공동주택의 경우에는 보다 합리적임을 파악하였고, 표준충격원은 경량 및 중량충격원을 사용하는 것이 타당하다고 판단된다. 또한 측정시 문제가 되는 63Hz 중심 주파수대역을 측정범위에서 제외하여도 차음성능 지수상의 오차는 무시할 수 있었다.

The purpose of this study was to analyze the planning characteristics and it's application of container architecture as case study. Field survey was used to analyze the spatial planning characteristics in terms of development outline, appearance, exterior, floor plan and interior of eight famous cases in Berlin, Hamburg, Hannover, Amsterdam and Paris of Europe. The results of this study were as follows; Firstly, good examples of container architectures such as student housing, social service center, temporary medical facility and cruise terminal in Europe suggested the potential of domestic applicability in various purposes and development. Secondly, various types of freight container, building container and module frame system should be developed with their reprocessing environment. Thirdly, it is necessary for us to develop ISO type(20~40ft) container and standard plan with interior and storage design reflecting demands of residents. Finally, the use of container module will be an environmental-friendly alternative for its modularity and reusability, so it should be used as it is without severe deformation. The development of environmental friendly energy sources such as hydro and solar power is necessary for domestic container architecture as well. The container design should include the use of high quality of exterior finishing materials and the plan of aesthetical color planning to make the building a local landmark.

This study was evaluated the applicability of the membrane filtration process (Micro Filtration (MF), nanofiltration membranes (NF), reverse osmosis (RO)) on the major radioactive substances, iodine ($I^-$) and cesium ($Cs^+$) using membranes produced in Korea and domestic raw water. Iodine ($I^-$) or cesium ($Cs^+$) in the microfiltration membrane (MF) process could not be expected removal efficiency by eliminating marginally at the combined state with colloidal and turbidity material. At the domestic raw water (lake water, turbidity 1.2 NTU, DOC 1.3 mg/L) conditions, nanofiltration membrane (NF) and reverse osmosis (RO) showed a high removal rate of about 88 ~ 99% for iodine ($I^-$) and cesium ($Cs^+$) and likely to be an alternative process for the removal of radioactive material.

The current status of Performance-Based Design (PBD) implemented in 4 wide areas (Seoul, Gyeonggi, Incheon and Busan) over the past 5 years was reviewed with regard to the number of PBD implementation and target buildings. Then, detailed status related to fire scenarios, input information for fire simulation, and grid size were analyzed with the pre-review for the PBD. As a result, the domestic PBD was mainly applied to the mixed occupancy. In the fire simulations performed on the identical fire scenario and fire space, the maximum heat release rate (HRR) varied significantly depending on the PBD designer. Various combustibles were also considered for the identical fire source, and their combustion properties also showed considerable uncertainty. In addition, the applicability of accurate input information for predictive models of heat and smoke detectors was examined. Finally, the average grid size for the fire simulation using Fire Dynamics Simulator (FDS) was analyzed, and the improvement of PBD to minimize designer dependency was proposed.

Safety' can be used in a variety of ways and may also have different meanings when used in theoretical field and routinely used. In this paper, the 'safety' means that human injury, fire or physical accident condition does not occur while used by the end-user. The meaning of safety may be different by era and culture. Even in contemporary era, the meaning can be used differently by country, region and culture. As the rights of consumers are increasingly reinforced, we can expect the acceptable risk or safety level can rise higher. In this paper, the R-map of Japan and the European risk assessment guidelines (RAPEX) were reviewed considering domestic incidents database status and its applicability. Because it is difficult to make a model based on a R-map, a revised model was developed mainly based on European Assessment Model with a combination of the important characteristics of Japan model R-map. Also utilizing this revised model, the availability as a new risk assessment model was confirmed by comparing the test results for the same scenarios to the other risk assessment model (RAPEX/RAG).
