Promoting low carbon transportation adoption is important for energy saving. Some prior studies have discussed on environmental values affect low carbon transportation commuting is inconclusive. This study has constructed the environmental values, utility value, and social influence-based low-carbon transportation adoption model through the theory of the technology acceptance model and VBN model and the IS success model. Through the SEM model and stepwise regression analysis, we have found that environmental values positively affect utility value, and utility value also positively affects the behavior adoption of low carbon transportation. The utility value as mediating effect in the relationship between environmental values and low carbon transportation commuting behavior. Besides, we also have found that social influence positively impacts the behavior adoption of low carbon transportation. It better enhances the level of household residents' environmental values and utility values, and social influence for promoting the adoption of low carbon transportation. This present research provides theoretical guidance and suggestions for promoting the development of low-carbon transportation innovation.

Observed wall damage in recent earthquakes in Chile and New Zealand, where modern building codes exist, exceeded expectations. In these earthquakes, structural wall damage included boundary crushing, reinforcement fracture, and global wall buckling. Recent laboratory tests also have demonstrated inadequate performance in some cases, indicating a need to review code provisions, identify shortcomings and make necessary revisions. Current modeling approaches used for slender structural walls adequately capture nonlinear flexural behavior; however, strength loss due to buckling of reinforcement and nonlinear and shear-flexure interaction are not adequately captured. Additional research is needed to address these issues. Recent tests of reinforced concrete coupling beams indicate that diagonally-reinforced beams detailed according to ACI 318-$11^1$ can sustain plastic rotations of about 6% prior to significant strength loss and that relatively simple modeling approaches in commercially available computer programs are capable of capturing the observed responses. Tests of conventionally-reinforced beams indicate less energy dissipation capacity and strength loss at approximately 4% rotation.

This study is to investigate multilateral environmental agreements,mainly UNFCCC on the primary export industry of Korea and to make a policy recommendation. Mostly literature reviews are focused on the traditional multilateral environmental agreements and the for the most part analysis are conducted prior to the Paris agreement. The result of survey indicates that many companies have not yet felt burden on their business due to UNFCCC(decarbonization) and have monitored the related policies. But the companies ask the government for strong incentives. The paper implies that enforcing strong government incentives, upgrading usage of the nuclear power, improving the related government legislation, setting up the special task force team with government and private sectors are needed.

The major purpose of this study is to construct a retrospective exposure assessment for benzene through a review of literature on Korea. Airborne benzene measurements reported in 34 articles were reviewed. A total of 15,729 individual measurements were compiled. Weighted arithmetic means [AM(w)] and their variance calculated across studies were summarized according to 5-year period intervals (prior to the 1970s through the 2010s) and industry type. Industries were classified according to Korea Standard Industrial Classification (KSIC) using information provided in the literature. We estimated quantitative retrospective exposure to benzene for each cell in the matrix through a combination of time and KSIC. Analysis of the AM(w) indicated reductions in exposure levels over time, regardless of industry, with mean levels prior to the 1980-1984 period of 50.4 ppm (n = 2,289), which dropped to 2.8 ppm (n = 305) in the 1990-1994 period, and to 0.1 ppm (n = 294) in the 1995-1999 period. There has been no improvement since the 2000s, when the AM(w) of 4.3 ppm (n = 6,211) for the 2005-2009 period and 4.5 ppm (n = 3,358) for the 2010-2013 period were estimated. A comparison by industry found no consistent patterns in the measurement results. Our estimated benzene measurements can be used to determine not only the possibility of retrospective exposure to benzene, but also to estimate the level of quantitative or semiquantitative retrospective exposure to benzene.

This study was conducted not only to review airborne asbestos levels reported in workplaces in Korea, but also to analyze their levels according to various characteristics All asbestos concentration reported as either geometric mean (GM) and geometric standard deviation (GSD) or ranges were transformed to arithmetic mean to estimate exposure level. In addition, weighted arithmetic means (WAMs) were calculated to weigh asbestos levels based on the different number of samples. Differences of asbestos levels among several characteristics such as industry type, decade, operation and sampling and analytical methods were analyzed using analysis of variance (ANOVA). The number of articles studying asbestos levels from workplaces was found to be 9 including two report types. Five of those were reported prior to 1990s and rest of them after 1990s. Only several industries such as asbestos textile, asbestos cement, brake-lining repair shops were studied, while various industries using asbestos or asbestos containing materials (ACMs) were not studied. ANOVA found that asbestos exposure levels (WAM = 5.26f/cc) reported from textile industry were significantly higher than those from other industries (cement = 0.63f/cc, brake-lining = 0.2f/cc - 0.47f/cc) (p < 0.0001). Average exposure levels studied prior to the 1990s (3.13f/cc) were found to be significantly higher than that (0.86f/cc) after the 1990s (p<0.0001). All WAMs reported until the 1994 were found to be higher than the current occupational exposure limits (0.1f/cc). This study recommends that retrospective exposure to asbestos based on various industry types and operations should be assessed.

Objectives: The goal of this study was to investigate the short-term effect of ambient air pollution on emergency department (ED) visits in Seoul for asthma according to patients' prior history of allergic diseases. Methods: Data on ED visits from 2005 to 2009 were obtained from the Health Insurance Review and Assessment Service. To evaluate the risk of ED visits for asthma related to ambient air pollutants (carbon monoxide [CO], nitrogen dioxide [$NO_2$], ozone [$O_3$], sulfur dioxide [$SO_2$], and particulate matter with an aerodynamic diameter <$10{\mu}m$ [$PM_{10}$]), a generalized additive model with a Poisson distribution was used; a single-lag model and a cumulative-effect model (average concentration over the previous 1-7 days) were also explored. The percent increase and 95% confidence interval (CI) were calculated for each interquartile range (IQR) increment in the concentration of each air pollutant. Subgroup analyses were done by age, gender, the presence of allergic disease, and season. Results: A total of 33 751 asthma attack cases were observed during the study period. The strongest association was a 9.6% increase (95% CI, 6.9% to 12.3%) in the risk of ED visits for asthma per IQR increase in $O_3$ concentration. IQR changes in $NO_2$ and $PM_{10}$ concentrations were also significantly associated with ED visits in the cumulative lag 7 model. Among patients with a prior history of allergic rhinitis or atopic dermatitis, the risk of ED visits for asthma per IQR increase in $PM_{10}$ concentration was higher (3.9%; 95% CI, 1.2% to 6.7%) than in patients with no such history. Conclusions: Ambient air pollutants were positively associated with ED visits for asthma, especially among subjects with a prior history of allergic rhinitis or atopic dermatitis.

This paper presents a comparative study on the effectiveness of teaching an engineering course using English with Specific Purpose(ESP). A study was performed using student groups; one class using ESP, and one class conducted in English with an English text. The course conducted using ESP showed the greatest improvement in English writing and conversation, and the students reported a greatly increased confidence in their ability to function professionally using English. A self-assessment of each student was conducted before and after the courses. Prior to the course less than 10% in each group felt that they are able to: a) understand a textbook, b) write an email, c) generate a project report, or d) follow a lecture given in English. The survey at the end of the course showed that the ESP teaching style resulted in significant improvements in students ability and confidence with writing and speaking in English, whereas reading skills were similar for both groups. This is due to the ESP method, in which students are required to give presentations and keep journals in English. After a brief review of the ESP principles and a discussion of how they were implemented, the background data of the participants(students) are described. Finally, the end-of-semester survey highlights the efficacy of the ESP approach.

As the world's attention turns to sustainability and the considerations of cumulative effects, the concept of Strategic Environmental Assessment(SEA) has become more significant and urgent and increasing number of countries and international organizations now undertake some forms of SEA. The term SEA, however, is variously defined and understood; generally it means a formal process of systematic analysis of the environmental effects on development policies, plans, programmes and other proposed strategic actions. This process extends the aims and principles of EIA upstream in the decision-making process, beyond the project level in which major alternatives are still open. There is a shift toward more integrative approaches and greater use of Environmental Impact Assessment (EIA) and Strategic Environmental Assessment (SEA) as sustainability tools in cooperation with Environmental Management System (EMS). Currently, Korea has EIA system and Prior Environmental Review System (PERS) which is different type of SEA as Environment Assessment (EA) system. APEMI IA MODEL integrated following three pillar(refer to attached figure.1) ; First pillar symbolized decision making cycle with planning process. Second pillar symbolized integrated assessment which tying SEA and EIA with specific impacts assessment(eg: social impact assessment, economic impact assessment, health impact assessment etc) in cooperation with EMS. Third pillar symbolized EA best practical procedure of International Association for Impact Assessment(IAIA). Considering the above, we applied new conceptual model(APEMI IA MODEL) into Impact Assessment for better integrated decision-making in KOREA as an alternative IA system(IS IA MODEL A and B refer to attached figure 4, 5).

환경영향평가는 대규모 개발사업을 대상으로, 계획 확정후 사업 실시단계에서 개발사업 시행에 따른 환경영향 저감방안을 중점 검토하는 제도인데, 사전환경성검토는 행정계획과 환경상 민감지역의 소규모 개발사업을 대상으로, 계획 확정 이전단계에서 환경적 측면에서 입지나 개발의 적정성 타당성을 사전에 검토하는 제도이다. 사전환경성검토는 2006년 6월부터 대상 행정계획을 구체적 개발사업의 상위 행정계획으로 확대하고, 계획의 적정성, 입지의 타당성을 미리 검토할 수 있도록 하고, 검토과정에서 주민, 전문가, 시민단체 등 이해관계자의 의견수렴을 거치도록 하는 전략환경평가 체제로 개편됨으로써, 환경갈등이나 사회 경제적 문제를 예방할 수 있는 기반을 보다 강화하였다. 환경부 주관의 사전환경성검토가 전략환경평가를 강화하는 동안 건설교통부가 중장기기본계획에 대한 전략환경평가를 시행하기 시작하였다. 우리나라의 전략환경평가는 건설교통부와 환경부가 전략환경평가를 별도로 운영하는 데 따른 비효율성, 국토계획과 환경계획의 연계성 부족, 선거공약으로 제안된 대규모 개발계획 등에 대한 객관적 환경평가의 어려움 등의 문제를 가지고 있다. 따라서 본 연구는 전략환경평가제도의 정립을 위해, 환경정책패러다임의 변천, 환경영향평가와 사전환경성검토의 발전, 전략환경평가의 현황과 선거공약으로 제안된 대규모 개발계획에 대한 전략환경평가의 한계 등을 고찰한 후, 전략환경평가제도의 발전방향과 개발계획과 환경계획의 연계통합방안을 모색하고자 한다.
