다자개발은행들은 기후변화 대응에 적극적으로 동참하고 있으며, 기존 환경·사회 영향평가에서 한발자국 더 나아가 저탄소 기후금융(Climate Finance) 제공을 위한 공동의 기후금융 평가방안(Common Principles for Climate Finance Tracking)을 마련하여 운용하고 있다. 이들은 보수적인 시각에서 전체 사업 중 기후변화 적응 또는 저감으로 인정할 수 있는 부분을 단위화하여 평가하고 있으며, 그 결과를 취합하여 2012년부터 2021년도까지 총 10회에 걸쳐 기후금융 보고서를 발간하였다. 기후금융으로 판단하는 방법은 저감인지 적응인지에 따라서 다소 상이하다. 기후변화 적응 금융의 경우에는 사업의 맥락, 전후사정을 살펴 적응 금융으로 산정하며, 저감 금융의 경우에는 적용이 가능한 사업에 대한 포괄적인 리스트가 마련되어 이에 해당하는 경우 저감 금융으로 인정한다. 다자개발은행은 기후금융 평가 내용을 환경·사회 영향평가 결과와 함께 사업 심사의 주요 항목으로 활용하고 있다. 세계 각국이 사업 수준에서 기후변화를 다루기 위한 다양한 노력을 기울이고 있는 상황에서, 다자개발은행이 사업 승인 시 기후변화를 어떻게 고려하고 있는지 살펴보고 그 시사점에 대해서 고찰해 보는 것은 향후 기후변화 대응 방법론 마련 및 관련한 환경·사회 영향평가의 역할 확대에 도움이 될 것이라고 생각한다.

Stress is now recognized as a universal premorbid factor associated with many risk factors of various chronic diseases. Acute stress may induce an individual's adaptive response to environmental demands. However, chronic, excessive stress causes cumulative negative impacts on health outcomes through "allostatic load". Thus, monitoring the quantified levels of long-term stress mediators would provide a timely opportunity for prevention or earlier intervention of stressrelated chronic illnesses. Although either acute or chronic stress could be quantified through measurement of changes in physiological parameters such as heart rate, blood pressure, and levels of various metabolic hormones, it is still elusive to interpret whether the changes in circulating levels of stress mediators such as cortisol can reflect the acute, chronic, or diurnal variations. Both serum and salivary cortisol levels reveal acute changes at a single point in time, but the overall long-term systemic cortisol exposure is difficult to evaluate due to circadian variations and its protein-binding capacity. Scalp hair has a fairy predictable growth rate of approximately 1 cm/month, and the most 1 cm segment approximates the last month's cortisol production as the mean value. The analysis of cortisol in hair is a highly promising technique for the retrospective assessment of chronic stress. [BMB Reports 2015; 48(4): 209-216]

The utilization of a variety of hazard chemicals bears risks to human health and ecosystem. The increasing usage of various chemicals indicates the greater emission of those chemicals to water system, and the subsequent deterioration of water quality. Water system is vulnerable to many pollutants, however, there are limitations of managing a range of hazard chemicals based on insufficient legal foundations. Therefore it is needed to select hazard chemicals that can be potentially discharged into water system, and subsequently to classify a wide range of existing chemicals for better management of those chemicals. In this study, the 259 candidate chemicals of concern were selected from the lists of the toxic released inventory chemicals (148), hazard concern candidate chemicals (106), and wastewater effluent standard candidate chemicals (116). We suggested the category 1, 2, 3 and 4 of hazard chemicals potentially discharged into water system. The assessment factors considered for the classification were hazard potential, persistence and emission to water body. This work was conducted as a part of the project entitled 'Development of integrated methodology for evaluation of water environment', and the results were used to develop the monitoring lists of hazard chemicals in four major rivers in Korea.

It is important to understand the trajectory of structure in launching process because of the short time of launching process may result in unexpected accidents or damage to structures. The high risk of structural failure is not avoidable without the fully comprehension of changing forces in launching procedure. The commercial software can evaluate the motion of launching event in calm water condition but there is the limitation of research application because of the programmed commercial software. The launching process of the spar hull is suggested with stage concept that is divided into 10 stages in time domain. A force equilibrium diagram is derived for each stage where the changes of force vector and motion characteristics take place. In particular, the effects of changes in buoyancy and drag force due to the progressive submergence of the spar hull are taken into account by means of a touch length concept. The results contained in this paper provide the valuable information of the trajectory motion evaluation with suggested methods in spar launching process with sliding barge. Furthermore, the presented stage concept and touch length concept will provide basic knowledge for understanding launching process and help to develop further research area for launching analysis.

The current methods, such as Binomial Probability Distribution or T-test, to calculate the number of samples of Precise Guided Missiles(PGMs) for test and evaluation are statistically problematic to make reasonable decisions thus use the budget efficiently. Also, the method to verify an accuracy rate of the PGMs using these old methods seems to be lack of objectiveness. This paper presents an effective, efficient solution adapted from the clinical medicine testing method of healthcare industry research, which may overcome our problems. This method considers and addresses both manufacturers' and consumers' risk simultaneously. By taking into account the weapon system project characteristics which take a relatively longer time and require higher-level budget, this approach also suggests a reasonable and feasible method to determine the amount of samples of the PGMs and making a criterion to verify an accuracy rate of the missiles that are required to test. Thus, this method is expected to contribute to acquisition and operations of high-reliability PGMs by MND and its field-users.

Background: The purpose of this study is to investigate the factors affecting the healthy living practice rate such as non-smoking, moderate drinking, walking, and low-salt diet by elementary municipality (so called, 'si-gun-hu'). Methods: The 2016 Korean Community Health Survey was used for the analysis. The theoretical model is founded upon the Anderson model, and both the multiple linear regression analysis and the beta regression analysis was performed for estimation. Results: As a result of the beta regression analysis, healthy living practice rate was found to be significantly higher in the areas with a less number of cigarette retailers, participating in healthy city projects, a low proportion of people who perceive their body type as obesity, a higher proportion of women, and a lower proportion of spouses. Conclusion: In order to improve healthy living practices, the regulations on health risk businesses, the spread of Healthy City project, and policy efforts awaring obesity are recommended.

Purpose - The purpose of this research is to discover whether the presence of the product average rating introduces biases or change the way people perceive information. We posit that review's overall rating has a predisposition effect on consumers' perception towards detailed review information. Research design, data, and methodology - To test these hypotheses, we conducted an empirical study on a real-world setting of online shopping platform. We choose the Amazon website to test our results. The data we use were collected by the Stanford Network Analysis Project1 (McAuley et al., 2013). Results - With a dataset containing reviews of seven product categories from amazon.com., our findings could possess more generalizability as they are produced on the typical and influential online market. Second, as our research provides alternative views of consumers' shopping behavior, it is better to test our hypotheses by data from the same source. Conclusions - Our study reveals the impact of the collective rating presence on consumers' diagnosticity perception and sheds light upon some of the conflictive results in prior studies. Our research generates implications to both theories and business practices, and suggests future directions for the research question.

최근 들어 소프트웨어의 복잡도와 규모의 증가와 함께 테스트의 중요성 또한 증대되고 있다. 테스트는 QA(Quality Assurance) 기간에 한정되지 않고 개발 기간에 꾸준히 적용 되어 자주 수행될수록 높은 품질 향상을 기대할 수 있다. 하지만, 지금까지 대다수의 테스트는 QA과정에 국한 되어 반복적이고 비 능률적인 매뉴얼 테스트 방법을 위주로 진행 되고 있다. 이는 코드 변경에 대해 효과적으로 회귀 테스트(Regression Test)를 수행할 수 없음을 의미하며 결과적으로 테스트를 자주 수행할수록 비용이 급격하게 증가하는 문제점을 가지고 있다. 본 논문에서는 이러한 문제점을 극복하기 위한 테스트 자동화 프레임워크(Framework)를 제안하고자 한다. 제안된 테스트 프레임워크는 테스트 테이블을 바탕으로 테스트를 가시적으로 설계할 수 있는 기능을 제공하며 스크립트 및 코드 작성을 최소화하여 적은 비용으로 빠른 시간 안에 테스트 자동화를 구현할 수 있도록 도와준다.
