Environmental specimen banks provide the baselines for the scientists and decision makers to do research using the past and present specimens to expect the possible contaminant implications of the future. Many chemicals that are considered harmless now but not found may be found and pose threats in the future. Collected specimens of animals and plants should be conserved without contamination for future analysis. To ensure the availability of samples for the retrospective analysis, the establishment and maintenance of specimen banks in the developing and developed nations has become absolutely necessary. National Environmental Specimen Bank (NESB) established at National Institute of Environmental Research (NIER) in 2009. For the application of NESB, several activities such as standard operating procedures (SOPs) development have been prepared. This study applied the guidelines for sampling and sample treatment of five environmental specimens which had been prepared from 2007 to 2009. The target species were shoots of red pine and Korean pine, leaves of Mongolian oak, eggs of domestic pigeon and muscles and livers of common carp. The NESB will enhance the quality of environmental assessment and environmental monitoring based on real time and retrospective analysis.

Assessment of geothermal resources like other earth resources is a starting point for decision makers or stakeholders to set up basic plan on its development and R&D policies. In this context, there have been various works on world geothermal assessment, to report different estimates from each other. In this paper, we first introduce the definition of geothermal potential mainly adopted from the article by Muffler and Cataldi (1978) and then summarize the estimates made so far referring the work by Bertani (2003). An updated estimates by Stefansson (2005) are also reviewed in terms of identified resources separately for high-temperature resources for power generation and low-temperature ones for direct-use. Recent estimate of US geothermal resources by MIT (2006) using a volumetric method with extensively accumulated data base is discussed. Finally, we introduce the first geothermal assessment in Korea recently made and discuss its importance.

To assess preliminarily the contamination potential of water resources including groundwater owing to the hydrogeological characteristics of landfill site and the potential impact to humans and animals through contamination of water resources by leachate, "Landfill Site Preliminary Assessment Model(LASPAS)" was contrived. LASPAS could help them proritization of remediation of landfil sites by the convenient and relatively simple evaluation method of landfill site features. LASPAS was designd to aliot numerical ratings to landfill site related factors undermentioned; 1) hydrogeological factors such as hydraulic conductivity of aquifer, thickness of confining layer over aquifer, topographical slope, net recharge, and subsurface containment 2) water resources contamination factors of impacts on receptors such as proximity to drinking water supply, substitutability of drinking water supply, type of use of water resources, known impact on drinking water supply, and flood potential.

The purpose of this study is to investigate factors influencing risk assessment of material misstatement in Vietnamese enterprises listed on stock market. Expert interview method was conducted to discover the scales for three variables including information system, trademark, and risk assessment of material misstatement. Survey method was used to examine the impacts of eight factors on risk assessment of material misstatement. Data is collected from 317 auditors who have excellent experience in auditing financial statements of companies listed on stock market. Then, data is processed by descriptive statistics, reliability analysis, factor extracted analysis, correlative regression analysis, and analysis variance of residual change. The research findings showed that business characteristic, stakeholder pressure, and economic environment have positive relationships with risk assessment of material misstatement. Three variables including operation control and monitor, control environment, and information system negatively affect to risk assessment. Specially, business characteristic and information system, which are elements in internal control, have strongest impact on risk assessment. One the other hand, assessment of internal control plays an important role not only in the audit plan stage but also throughout the stages of the audit implementation and ending. Therefore, appropriate solutions are proposed to carry out all audit stages.

생태생태관광자원의 지속가능성을 평가하기 위해 생태관광과 관련한 전문가 집단 135명을 대상으로 설문조사하여 지속가능성에 크게 영향을 미치는 중요요인에 대한 가중치의 산정, 평가지표의 개발 및 수리적 평가모형을 정의하여 우포늪을 대상으로 평가를 실행하였다. 그 결과 현재 상태의 우포늪에 대한 지속가능성 등급수준을 확인하였으며, 등급수준의 상향을 위해 세부항목별 향상방안을 제시하였다. 본 논문은 우포늪을 대상으로 하였으나, 생태관광자원의 지속가능성 평가에 대한 구체적인 연구모형과 방법을 제시함으로써 보다 과학적이며 체계적으로 지속가능성을 평가할 수 있는 근거를 마련하였다는 점에서 의미가 크다.

The energy production of offshore wind farms plays an important role in expanding renewable energy. However, the development of offshore wind farms faces many challenges due to its incompatibility with marine environments and its social acceptability among the local community. In this study, we reviewed the marine environmental impact assessment status of offshore wind farm development projects for 2012-2019 in South Korea. A total of nine projects were selected for this study, all of which experienced considerable conflict with local fisheries resources. To appropriately respond to the underlying challenges faced by offshore wind farm development and in order to better support decision-making for future impact assessment, our findings identified: i) a need for adequate preliminary investigation and technical examination of fisheries resources; ii) a need to assess and estimate the impact of underwater noise, vibration, and electromagnetic waves on fisheries resources during wind farm construction and operation; and iii) a need for a bottom-up approach that allows for communication with local stakeholders and policy-makers to guarantee the local acceptability of the development.

본 연구에서는 국내 폐광산에 이용될 채움재의 위해성 평가작업을 위한 전략과 방법론을 개념적 측면에서 제시하였다. 채움재는 석탄발전소 비산재와 고형재로 구성되어 있으며 탄산염 등 위해도가 적은 물질이 대부분을 차지하지만 일부 중금속 성분이 포함되어 있어서 이에 대한 위해성 평가가 요구된다. 위해성 평가는 주로 인체내 발암 및 비발암성 유발 가능성을 정량화하는 것이 목적이며, 본 연구의 경우 국내/외 토양 및 광해 위해성평가 기법을 참조 할 수 있을 것으로 판단된다. 이 때 독성이나 분배계수 등 항목별 주요 은 인자 값은 국내 토양위해성평가 가이드라인에서 제시하는 수치를 주로 이용할 수 있다. 오염도에 대한 정확한 위해 성평가는 현장답사와 실측 등을 통한 노력과 시간이 요구된다. 또한 채움재내 중금속 성분 및 농도가 매우 다양하고 반응이 복잡하여 이를 전부 상세하게 평가한다는 것은 비효율적이다. 따라서, 효과적인 위해성 평가를 위하여 일단 문헌 자료와 채움재 시료특성분석결과를 이용한 예비위해성평가를 먼저 실시하고, 그 이후 상세 위해성 평가에서 예비위해성평가에서 선정된 유의 사항을 중점적으로 다뤄야 할 것으로 생각된다. 이를 위해서는 신뢰성 있는 시료분석기법과 노출경로 및 관련 메커니즘에 대한 충분한 이해가 선행되어야 한다.
