Green technology encompasses a growing group of methods and materials, from techniques for generating energy and alternative resources to non-toxic cleaning products. Green technology is expected to solve current problems in atmospheric environment such as climate changes due to green house gases and hazardous air pollutants. This paper provides a review on the status of green technology and policy guidelines in Korea as well as the green technology for air pollutants. It presents the R&D projects and future direction in atmospheric environment, and the green technology in mobile source air pollution. Emerging green technology contributes to sustainable growth and development of atmospheric environmental industry for better air quality.

Recently many countries agreed to reduce emissions of greenhouse gases into the atmosphere or at least to keep them at the current level at the Kyoto Protocol. Carbon dioxide has been proven to be 80% of greenhouse gases, contributing to the increase of the earth's surface temperature. It is reported that half of the $CO_2$ emissions are produced by industry and power plants using fossil fuels. In this article, we review and analysis domestic and abroad R & D policy trends relating to UN framework convention on climate change(UNFCCC).

This study is to develope the job stress model for workers in fashion and textile industries and to investigate the effect of job stressors on stress symptom and its effect on job performance. The structural equation model analysis was performed for examining the relationship among job stressors, stress symptom and job performance. Environmental factors, task factors, role factors and organizational climate factors were identified as job stressors. Task characteristics and role characteristics were positively related to job stress symptom. Environmental factors and organizational climate factors were negatively related to job stress symptom. Also, job stress symptom was negatively related to job performance. The findings suggest some implications on how to improve job performance or to reduce job stress.

This study has been analyzed an execution example of the life cycle assessment on the packaged bean-curd of P company, the first case of the regular life cycle assessment on the processed foods in Korea and considered on the significance and directions of the life cycle assessment on the foods. It is possible to divide the potential environmental impact through the life cycle of the bean-curd into six categories and analyze the environmental impact on the production, use and disposal phases of the product. The values of each environmental impact have been quantified from the strength of the potential impact fur the corresponding category of impact. In the future, it is expected that the result of the lift cycle assessment will be increasingly used fur many areas such as Climate Change Convention and ISO22000, etc. and it is required to promote a project to make database through the assessment on the individual corps or types of businesses for it from now on.

The government should establish internationally harmonious regulations for effective import and export of necessary resources to other countries. However, the use and the number of pesticides used for the same purpose on same crops are depending on the soil and the climate where the crops are grown. Therefore, if internationally harmonized standards are difficult to establish, it is mandatory to conduct a risk assessment based on scientific data to reflect the domestic situation in order to avoid trade friction or conflict between countries. The government is preparing the implementation of a more regulated PLS (positive list systme) than the existing pesticide management system for safer pesticide management reflecting the recent increasing imported food, changing dietary habits, and changing climate. In order for effectively safe and scientific management of pesticides, the government should strive to communicate with consumers properly and the perception of pesticides by consumers should also be changed.

본 연구는 겨울철 휴면심도와 동해유발온도를 기반으로 작성된 복숭아 나무 '장호원황도' 품종의 휴면지에 대한 동해위험지수 계산식을 고해상도 전자기후도와 결합하여 현재평년(1971-2000년)의 기후조건에서 동해위험의 지역적 분포를 파악하였다. 이를 기준으로 두고 기후변화 시나리오에 근거한 미래 3개 평년(2011-2040년, 2041-2070년, 2071-2100년)의 기온자료에 동일한 방법을 적용하여 얻은 동해위험지수와 비교함으로써 기후변화에 따른 이들 위험지역의 이동을 경관규모에서 추적하였다. 현재평년(1971-2000년) 기후조건에서는 전 국토의 4%가 안전지대, 88%가 동해 위험 경계지대, 8%가 위험지대로 탐색되었다. 시나리오 기후조건에서는 가까운 미래(2011-2040년)와 먼 미래(2041-2100년)에 모두 경계지대가 줄어드는 반면 안전지대와 위험지대가 다같이 증가하였다. 이 방법은 경기도 이천, 경북 청도 등 복숭아 주산지 내의 위험지대를 경관규모에서 탐색하는 데도 이용될 수 있음이 확인되었으므로 앞으로 농업분야 기후변화 영향평가 및 취약성 분석에 기여할 것으로 기대된다.

본 논문은 최근 공표된 Post-2020 신기후체제의 국가적 대응에 따른 발전부문의 역할들을 시나리오로 설정하여 경제적 파급효과를 비교 분석 하였다. 이를 위해 제7차 전력수급기본계획에서 제시한 2030년 발전원별 추정 발전량에 IAEA에서 발표한 온실가스 배출계수를 적용하여 온실가스 배출량을 예측하여 발전부문에서 발생시키는 초과 배출량을 산정하였다. 초과 배출량 감축을 위해 세 가지 시나리오를 기반으로 하였으며, 이들은 원자력발전소로 대체, 신재생발전설비 확대, CCS 도입 등이다. 분석 결과 원자력 발전소 대체 시나리오가 배출량 감소 및 경제적인 측면에서 가장 긍정적인 결과를 보였다.

This study was conducted to estimate of carbon stock and greenhouse gas (GHGs) removals by tree species and forest type at Gangwon province. We used a point sampling data with permanent sample plots in national forest inventory and national emission factors. GHGs emissions was caclulated using the stock change method related to K-MRV and IPCC guidance. Total carbon stock and greenhouse gas removals were high in deciduous forest and species than in coniferous. The range of annual net greenhouse gas emissions in other deciduous species was from $-11,564.83Gg\;CO_2\;yr^{-1}$ to $-13,500.60Gg\;CO_2\;yr^{-1}$ during 3 years (2011~2013). On the other hand, coniferous forest was temporally converted to source due to reducing of growing stock in 2012. It was that growing stocks and forest area were likely to reduce by the deforestation and clear cutting. This study did not consider other carbon pools (soil and dead organic matter) due to the lack of data. This study needs to complement the activity data and emission factors, and then will find the way to calculate the greenhouse gas emissions and removals in the near future.

해운 부문의 배출량이 지구 기후 변화 논쟁에서 큰 역할을 한다는 데는 폭넓은 합의가 있다. 이론적으로는 업계가 온실가스 배출을 줄이기 위해 단호한 조치를 취하고 지구 온난화에 대응하기 위해 자신의 역할을 다해야 한다는 광범위한 공감대가 형성되어 있다. 미국은 선박의 배출 문제를 해결하는 데 큰 진전을 이루었지만 해운 산업의 글로벌 표준을 형성하는데 중요한 역할을 하는 것은 IMO이다. 그리고 한국의 경우 배출문제에 대한 법 제정 등이 준비되었지만 여전히 행정력에서 문제를 보이고 있다. 앞에서 살펴본 IMO의 높은 수준의 비전제시 및 변화는 업계 대표자들의 강도 높은 노력을 요구하며 실행 책임을 지고 있는 정부로 하여금 강도 높은 조치를 요구하고 있다. 규제와 해운시장의 입장을 고려할 필요가 있다. 하지만 지구 기후 변화의 긴급한 현실에 대한 배려와 존중을 위해 선박 소유자, 운영자 및 지주 회사는 새로운 규제 체제를 기다리는 대신 GHG 배출을 줄이기 위한 자발적인 조치를 취해야 할 것이다.

The purpose of this study was to investigate job stressors, job stress symptoms, and job performance of workers in fashion industry. The data were obtained from questionnaire completed by 529 workers who were employed in textile or clothing manufactures located in Seoul, Daegu, Busan, and Masan area. The SPSS package was used for data analysis which included frequency, mean, correlation, and factor analysis. Job stressors consisted of environmental related stressors, job related stressors(task characteristics and role characteristics) and organization related stressors(organization climate and career development). Most of job stressors were significantly correlated with job stress symptoms but their correlation coefficients were low. Among job stressors, quantitative work overload was found to be a major stressor. Workers in fashion industry appeared to evaluate their job performance relatively good. Also, it was found that behavioral and psychological symptoms were negatively correlated with job performance.
