Background: A quantitative structure-activity relationship (QSAR) model was adopted in the Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH, EU) regulations as well as the Act on Registration, Evaluation, etc. of Chemicals (AREC, Republic of Korea). It has been previously used in the registration of chemicals. Objectives: In this study, we investigated the correlation between the predicted data provided by three prediction programs using a QSAR model and actual experimental results (acute fish, daphnia magna toxicity). Through this approach, we aimed to effectively conjecture on the performance and determine the most applicable programs when designating toxic substances through the AREC. Methods: Chemicals that had been registered and evaluated in the Toxic Chemicals Control Act (TCCA, Republic of Korea) were selected for this study. Two prediction programs developed and operated by the U.S. EPA - the Ecological Structure-Activity Relationship (ECOSAR) and Toxicity Estimation Software Tool (T.E.S.T.) models - were utilized along with the TOPKAT (Toxicity Prediction by Komputer Assisted Technology) commercial program. The applicability of these three programs was evaluated according to three parameters: accuracy, sensitivity, and specificity. Results: The prediction analysis on fish and daphnia magna in the three programs showed that the TOPKAT program had better sensitivity than the others. Conclusions: Although the predictive performance of the TOPKAT program when using a single predictive program was found to perform well in toxic substance designation, using a single program involves many restrictions. It is necessary to validate the reliability of predictions by utilizing multiple methods when applying the prediction program to the regulation of chemicals.

Environmental designers in Korea have shown interests in Environomental Psychology and Behavior Studies (EPBS) since 1970's. However, many designers, who have expected a great deal of contribution from the EPBS, have disappointed due to their overexpectation and misunderstanding on the EPBS. This study intends to analyse the nature of the EPBS and to investigate the potential contribution of the EPBS to the field of environmental design. The EPBS are able to help designers by providing scentific data in each stage of the design process. Further, most design theories and principles are based on the findings of the EPBS. Thus the development of the EPBS has great potential of contribution to the development of design theories arid principles Due to the scientific nature of the EPBS, however, the EPBS have difficulties in supplying scientific data within relatively short period, which make most designers impatient. Designers should understand the scientific nature of the EPBS and be patient in expecting usable outcome from the EPBS. Further, Designers should not expect the EPBS give them design soultion itself.

This study measured the energy recovery rate of each municipal waste incineration facility according to the revised energy recovery rate estimation method, which targeted four municipal waste incineration facilities (Unit No. 7). The results calculated by the measuring instruments were used for each factor to estimate the recovery rate, and the available potential of available energy was examined by analyzing the energy production and valid consumption. As a result of the low heating value, 2,540 kcal/kg was calculated on average when the LHVw formula was applied, which is approximately 116 kcal/kg higher than the average design standard of 2,424 kcal/kg. The energy recovery rate was calculated as 96.9% on average based on production and 67.5% based on effective consumption, and the analysis shows that approximately 29.4% energy can be used.

The main purpose of this study is to analyze and evaluate the types of environmental awareness as an eco-friendly/non-eco consumer among Korean University students. The data of research were collected by a survey questionnaire with face-to-face interviews in South Korea. The questionnaire was consisted of fifty-six variables with five questions of demographic factors. The variables employed in the survey were drawn from the literature review and suggested by the focus group to make the questionnaire influential in studying the trends of eco-friendly consumers. Descriptive statistics and binary logistic regression modeling were used by two groups of the student consumers to find the significance of each factors; practice, habit, recognition, concern, and insistence. Environment-friendly consumers show significant difference with non eco-friendly consumers including practice, habit, and concern toward environmental issues.

해양환경에 관한 정보는 효율적인 연안 해역 관리를 위해 필수적이며, 해양환경요소에 대한 분석을 위해 현장 실측자료뿐 아니라 과거자료, 현재자료, 예측자료 등이 요구된다. 또한 연안환경 관리자뿐 아니라 해상관련 종사자, 어민 등이 해양환경 정보에 빠르게 쉽게 접근할 있는 기반이 마련되어야 한다. 최근에는 물에 관련된 정보를 효율적으로 관리하고 제공해야 하는 필요성이 증가함에 따라 물정보학(Hydroinformatics)이 크게 관심을 받고 있으며, 학술지 발간 및 학술회의 개최 등을 통해 이에 관한 연구가 활발히 진행되고 있으나 연안환경에 대한 연구는 미흡한 실정이다. 체계적인 연안환경 분석을 위해서는 방대한 시공간 자료가 필요할 것으로 예상되며, 지속적인 모니터링을 위한 통합시스템이 요구되므로 다양한 관측방법 적용될 필요가 있다. 본 연구에서는 인공위성을 활용하여 연안환경 변화를 모니터링 할 수 있는 방안을 제안하기 위해 국외의 연구사례들을 분석하고, 우리나라 연안환경에 적합한 위성을 조사함으로써 연안환경 분석과 관련하여 관측 가능한 인자들을 파악하고자 한다. 이를 통해 연안환경 모니터링을 보다 체계적으로 수행하기 위한 인공위성 기법의 특징들을 이해하는 것이 본 연구의 목적이다. 향후 서해안지역의 연안 환경 변화 탐지를 위한 알고리즘을 구축하여 한반도 연안환경분석을 위한 인공위성의 유용성을 검증할 계획이다.

환경은 경제에 대한 투입과정에서 자원을 제공할 뿐만 아니라 생산과정 내 폐기물을 정화시키는 역할도 한다. 이러한 과정을 통해 환경은 경제와 연결되어 끊임없는 재순환이 일어난다. 경북대 에너지환경경제연구소는 이러한 순환관계의 규명을 통해 에너지환경의 지속가능한 발전을 목표로 하고 있다. 이에 따라 각 연구부가 구성되어 분야별로 연구를 수행하고 있다. 각부간의 연구분야는 조직으로는 분리되어 있으나 연구소의 연구 내용의 특성상 부서간 개별적 연구보다는 협조적 연구가 실제적으로 이루어지고 있다.

본 연구는 미국 소재 T 대학교의 학생아파트를 대상으로 하여 창밖으로 보이는 외부 환경의 차이와 거주자의 환경조절 행태 사이의 관계를 분석하는 관찰연구로 진행되었다. 거주자와 거주환경간에 발생하는 부조화는 환경 스트레스의 한 원인이 된다. 이러한 환경 스트레스에 대한 대응 전략으로 거주자는 그들의 환경을 조정하곤 한다. 본 연구는 실내에서 식물을 키우거나 거주자의 취향에 따라 커튼을 교체하는 등의 환경조절 행태를 분석의 대상으로 한다. 창문과 현관 영역에서 발생하는 환경조절 행태의 정도를 비교 관찰하기 위해 군집형과 일자형으로 되어 있는 두 개의 배치 유형을 연구의 대상으로 선정하였다. 군집형 유형(cluster type: type A)은 상대적으로 도로에 가깝고 거실 창문의 조망이 다른 건물에 가로막혀 있으며, 일자형 유형(parallel type: type B)은 가로막고 있는 건물이 없어 자연경관을 거실 창문을 통해 조망할 수 있는 배치상의 두드러진 차이점이 있다. 관찰연구를 통해 군집형 유형에서 일자형 유형보다 더 높은 빈도로 식물 화분과 개별 커튼 등을 이용한 개인적 환경조절이 이루어진 흔적이 발견되었다. 이러한 결과는 창문을 통해 보이는 외부 경관의 특성이 거주자의 환경조절 행태에 미치는 영향의 정도를 암시하고 있다. 결론적으로 관찰연구에서 나타난 거주자의 환경조정 행태를 반영하여 디자인 고려사항을 제안하였다.

In this research I investigate different firm characteristics between environment-friendly companies which are awarded by the Government and companies which violate environmental regulations. I set up three hypotheses in terms of managers' environmental attitude and firms' characteristic in technical, financial and structural aspects, considering environmental experts' opinions and findings of previous papers. Main research findings are as follows. First, both acquisition of the ISO 14001 certificate and ownership structure are used as proxy of top management attitude towards environmental decision-making. It is hypothesized that it is found that the certificates of ISO 14001 is a good proxy to represent top management environmental attitude and a firm with the certificate would have less likelihood of violation. Second, it is hypothesized that technical ability affects violation tendency of environmental regulations. It is found that as R&D investment increases, violation likelihood of environmetal regulations decrease. It can be conjectured that R&D investment may improve technical abilities of observing environment regulations. Third, it is investigated whether a firm's financial capability affects violation tendency of environmental regulations. Fourth structural aspects of a firm such as capital intensity, the number of employees and export ratio are investigated. It is found that a firm with more employees per sale amount tends to violate environmental regulations. It is not found any effects of expert ratio nor capital intensity on violation tendency of environmental regulation.
