In this paper, an optimal manufacturing system design problem in an automotive body assembly lines is introduced when various costs such as equipment investment costs are considered. Meta-model methodology based on simulation results has been used for estimating the performances of the system such as production rate and work-in-process levels. The objective function is minimizing total cost which satisfies the target production rate. The investment costs such as robots, buffers, transportation equipment, and the inventory holding cost of work-in-process have been included in the objective function. Harmony search method has been used for optimization.

Life cycle assessment (LCA) has become an important tool used to enhance the environmental performance of process systems and products. LCA is an essential element in design for environment (DfE) because LCA can be utilized to evaluate and analyze environmental impacts incurred in the life cycle and supply chain. This review presents methodologies that can be used to integrate LCA into DfE activities and reduce environmental impacts from process systems and products; and introduces case studies for water supply systems and cellular phones. LCA is first used to quantify environmental impacts and identify the principal contributor to high impacts. In the next step, environmental impacts from principal contributors can be reduced by using mathematical optimization tools as an engineering and technological approach and by utilizing the cooperation of professionals from a diverse range of fields. Because the methodologies and case studies can be applied and extended to other fields, this review paper can contribute to helping prevent environmental pollution and enhance the sustainability of our society.

This study examine operating system for eco-friendly container terminal and shows the usefulness of the Importance-performance analysis grid in evaluating container terminal operating technology. Importance-performance analysis enables management to evaluate and identify the major strengths and weaknesses of eco-friendly container terminal operating technology's key success factors. This study identified a list of 20 items from the eco-friendly container terminal literature reviews, and each item was rated using a 5-point Likert scale. Responses were obtained from 250 questionnaires. The importance-performance grid shows that 13 items fall into the "Keep up the good work" quadrant, 2 items fall into the "Concentrate here" quadrant, 2 items fall into the "Low priority" quadrant, and 3 items fall into the "Possible overkill" quadrant. The findings suggest that an eco-friendly container terminal operating technology is necessary to enhance eco-friendly operating system. The results are useful in identifying areas for strategic focus to help container terminal managers develop eco-friendly container terminal operating technology strategies.

This study investigates the factors that induce the early adoption of environmentally friendly vehicles. We measure the affective, cognitive, and behavioral factors influencing the early adoption intentions of car owners in three countries (the US, Germany, and Japan). We find that affective and cognitive factors are significant, but behavioral factors are only partially significant. Specifically, eco-centric values and knowledge about green technology are significant in explaining early adoption intent. However, of the behavioral factors, usage context is significant, whereas commute distance is not significant in explaining early adoption intent. Finally, between-country differences indicate that any policy to increase the adoption of environmentally friendly vehicles should be fine-tuned for each country.

The market participation and development of major manufacturers of next-generation green vehicles is accelerating in recent years. The results of this study are as follows: Consumer type (personal value pursuit type, price value pursuit type) was significant difference between consumer. The results of this study were as follows: First, there was no significant difference in the characteristics of consumers (gender, age, monthly average income) and purchase intention according to age, gender and monthly average income, Image has a positive (+) impact on eco-friendly vehicles. This suggests that the development and market participation of next - generation green vehicles is accelerating and consumers 'interest is increasing, and the characteristics of environment - friendly vehicles and the government' s policy support are important factors.

Recently, sick house syndrome caused by pollutants and contamination of buildings crops out in residential environment of buildings. According to price increase of global oil, comfort of occupants in indoor air quality is required with reduction of energy consumption and environmental load. So, building performance certification criteria come into effect for improvement of building energy efficiency and performance in environment at home and abroad. GBCC(Green Building Certification Criteria) of domestic country as a Criteria is managed Korea Green Building Council(KGBC) for green building. Thus, purpose of this study is to design a direction of Green Building Certification Criteria for improvement through analysis of GBCC application elements and selected building.

이미 알려진 바와 같이 차세대 차량에 채용될 동력 시스템의 연구개발이 배출가스 규제에 대한 배기 성능의 획기적 개선에 집중되고 있는 한편, 포괄적 친환경 차량 개발 또한 일반의 관심을 끌고 있다. 현재에 이르기까지 배출가스 규제치 즉, 대기로 배출되는 질소산화물(NOx), 입자상물질(Particulate Matter, PM) 및 미연탄화수소 등에 대한 정량적 규제치의 만족여부가 차량의 친환경 여부를 가리는 척도로 주로 인식되어 왔으나, 금후 보다 본격적으로 완성차량 조립을 위한 전 제품의 제조과정으로부터 차량 폐기까지를 총괄한 포괄적 환경 영향 평가가 필수 불가결한 요소로 등장하리라 예측된다.

2006년 축산물가공처리법이 개정되면서 축산농가(가축사육단계) 위해요소중점관리 기준이 도입된 이후 HACCP인증에 대한 농가의 관심이 증가하고 있다. 산란계농장 213개소, 육계농장 168개소로 총 381개소 양계농장이 HACCP(20101.11.8일 기준)을 인증 받았고, 앞으로도 친환경사육에 대한 농가 참여율이 높아질 것으로 예상된다. 30년 전부터 양계 경영에 남다른 애착을 갖고 시작해 친환경사육 방식으로 지난 3월 HACCP를 인증 받은 농장이 있다. 경기도 용인시 처인구 소재에 위치한 소현농장으로 부친의 가업을 이어받아 건강한 계란 생산을 위해 노력하고 있다.
