  • A variety of Certification systems are initiated, as increased demands for housing quality of building & house owner. New building and apartment built in Seoul metropolitan should acquire Building Energy Rating System and Housing Performance Grade indication System, Green Building Certification System. Building Energy Rating System could be acquired through the certification from energy performance index of environment grade in Housing Performance Grade Indication. Between Housing Performance Grade Indication and Green Building Certification System, There are troublesome to acquire certification because a lot of assessment items are overlapped. At a result, the rational and efficient certification system should be initiated not only to avoid overlap among those certification systems and promote Green Building market share but also efficient certification system operation. We will discuss on assessment items between Housing Performance Grade Indication System and Green Building Certification System and release the improvement method those Certification Systems to avoid overlapping to assessment items.

  • Background: Methodologies for a series of radiological consequence assessments show a distinctive difference according to the design principles of the original nuclear suppliers and their technical standards to be imposed. This is due to the uncertainties of the accidental source term, radionuclide behavior in the environment, and subsequent radiological dose. Both types of PWR and PHWR are operated in Korea. However, technical standards for evaluating atmospheric dispersion have been enacted based on the U.S. NRC's positions regardless of the reactor types. For this reason, it might cause a controversy between the licensor and licensee of a nuclear power plant. Materials and Methods: It was modelled under the framework of the NRC Regulatory Guide 1.145 for light-water reactors, reflecting the features of heavy-water reactors as specified in the Canadian National Standard and the modelling features in MACCS2, such as atmospheric diffusion coefficient, ground deposition, surface roughness, radioactive plume depletion, and exposure from ground deposition. Results and Discussion: An integrated accident consequence assessment code, ACCESS (Accident Consequence Assessment Code for Evaluating Site Suitability), was developed by taking into account the unique regulatory positions for reactor types under the framework of the current Korean technical standards. Field tracer experiments and hand calculations have been carried out for validation and verification of the models. Conclusion: The modelling approaches of ACCESS and its features are introduced, and its applicative results for a hypothetical accidental scenario are comprehensively discussed. In an applicative study, the predicted results by the light-water reactor assessment model were higher than those by other models in terms of total doses.

  • Soil quality assessment is an important tool for environmental management in an agricultural field. It can be used to evaluate the health of the soils and to establish the basis for sustainable urban agriculture and soil management. For this study, the chemical properties of the soils used for urban agriculture were examined. Results of the soil analysis for chemical properties were applied to soil quality assessment system, which is composed of principal component analysis, application to scoring function and derivation of soil quality index (SQI). Soil pH, electrical conductivity (EC), organic matter (OM), total nitrogen (T-N) were determined for minimum data set (MDS) according to principal component analysis. Based on the results of scoring for four indicators (pH, EC, OM, T-N), soil pH was the indicator that needs the most urgent management. Results of SQI derivation showed that many of the urban farms appeared to be insufficient score in comprehensive soil quality assessment. In conclusion, soil management practices based on scores derived from soil chemical indicators need to be carried out to maintain sustainable urban agricultural soil environment and to provide easy-to-understand information to urban farmers.

  • Environmental monitoring system has been adopted and supplemented as inspection measures for the quantitative and qualitative changes of environmental impact assessment (EIA). Meanwhile it has been continuously pointed out that there is insufficient connection between environmental monitoring system and EIA. Often the agreed environmental impact assessment has not been fulfilled due to the argument of the cost, timing and situations of construction sites. Thus the purpose of this study is in search of the rationalized environmental monitoring system in order to harmonize the development and environmental conservation through the improvement of unreasonable aspects of the current EIA execution process. As to comply with the purpose, this research was carried out with three different but complimentary sources: environmental laws and regulations, foreign case studies of Japan, U.S.A. and Canada, and interviews with 73 experts. Finally, improved environmental monitoring system has been introduced reflecting the present process of EIA.

  • 산업곤충은 부가가치를 창출하는 산업에 이용되는 곤충으로 정의된다. 일반적으로 국내 통용되고 있는 산업곤충의 대부분이 외래종이며, 인위적 유입으로 기인한 것이다. 산업곤충 시장의 급속한 확장에도 불구하고 산업곤충의 위해성평가를 위한 시스템은 적절하게 수행되지 않는다. 국내 수입곤충의 경우 농림축산검역본부에서 금지병해충으로 지정한 종에 대한 위험평가를 실시하여 외래종을 유입하고 있지만, 그 관리체계가"식물방역법" 체계에서 다루어지기 때문에 생태계 전반의 고려가 이루어지지 않는 한계가 있다. 이 문제를 해결하기 위해 국내 제도의 현황과 외국 평가체계를 살펴보았다. 분석결과, 우리나라 산업곤충 분야의 성공적인 제도적 관리를 위해서는 기본적 방향설정에 대한 합의가 필요한 것으로 분석되었고 이를 제안하였다. 또한, 위해성평가는 분류학 및 생태학적 정보의 통합 시스템이 준비되지 않는 한, 생태계를 보호하고 사전예방원칙을 따르도록 해야 하며 각 부처 간의 협력이 중요한 것으로 나타났다. 이와 함께 산업용 곤충의 위해성 평가와 위해성 심사체계의 구분이 시급한 개선사항으로 분석되었다. 위해성 평가와 위해성 심사목적, 대상, 신청기관, 위해성 평가기준의 마련을 제안하였다. 국외에서 시행되는 위해성평가체계 중에서 아일랜드의 평가체계는 경제성, 생태적 안전성, 관리적 측면 등 다양한 요소를 균형적으로 고려한 평가체계이며 사전예방주의에 입각한 것으로 분석되었다. 이는 우리나라 곤충산업의 특수성을 고려하여 산업곤충으로 인한 피해를 사전적으로 예방할 수 있는 국내 시스템으로 응용할 수 있을 것이라 사료된다.

  • In this study, we investigated the relationships among elementary school teachers' perceptions of constructivist science assessment, views on science teaching and learning, science teaching efficacy belief, and the perceptions of constructivist science learning environment. An exploratory factor analysis was conducted to validate the factor structure of the perceptions of constructivist science assessment test. The test consisting of 3 factors with 21 questions in the previous research was reconstructed as one consisting of 2 factors with 22 questions as a result of the factor analysis. A stepwise multiple regression analysis was also conducted to predict the explanatory powers of the variables on perceptions of constructivist science assessment. The results indicated that the perceptions of constructivist science learning environment, views on constructivist science teaching and learning, and personal science teaching efficacy belief were the significant predictors of the perceptions of constructivist science assessment.

  • This paper compared the consistency of the Environment Stress(ES) model and the Potential Risk Assessment Model (PARK model, which was developed based on a Korean mariner risk perception) for the Busan adjacent waterway. Evaluation of accuracy and comparison of these two models have been made by Vessel Traffic Service (VTS) officers in the Busan VTS Centre. The assessment results of Busan waterway show that the PARK model is more consistent than the ES model as follows. (1) The difference between assessment results applying ES model and PARK model with risk degree of VTSOs were 34% and 5% respectively in six typical traffic situations. (2) The assessment using PARK model is more suitable and identical with the VTSOs opinion in his or her duty time.
