  • Recently, it has been increasing for the eco-environment plating and surface treatment of eco-environment to decrease hazardous materials. Particular eco-environment can be applied to electronics or automotive parts of industry. In the case of mobile phone, if there were fired, the products bearing dye may be contaminated with the hazardous and wasted. we can obtain the original metal color by electro coloring by metal salt, get rid of hazardous gas, decrease the wasted sludges. Now, the industrial patent number is increasing in Korea, we can accomplish the development of green industry by supporting technical trend of the plating and surface treatment in eco-environment.

  • The purpose of the study is to analyze the effects of customer satisfaction verses eco-friendly agricultural products (ingredients) awareness factors in luxury hotel Chinese restaurants on hotel image and customer loyalty (repurchase intention). To analyze what kind of effects of customer satisfaction verses eco-friendly agricultural products (ingredients) awareness factors in Chinese restaurants have on hotel image and behavior intention (loyalty), the study identified eco-friendly ingredients awareness factors. The study aims to suggest implications on service strategies and marketing strategies in luxury hotel Chinese restaurants based on the influence of customer satisfaction on hotel image and behavior intention (loyalty) using the identified factors.

  • 경량성, 자원의 무한성 그리고 재활용성으로 대표되는 친환경의 마그네슘은 향후 Eco-Mg 개발을 통하여 무한한 성장이 예상된다. 본 자료에서는 첨가제로서의 CaO 관점에서 $non-SF_6$ 공정, 유동성의 공정 대응성, 압출 대응성, 스트립 캐스팅 대응성, 압연 대응성, 접합 대응성 그리고 마그네슘 합금의 산화 저항성 및 발화 저항성에 대해서 서술하였다. 또한 첨가제로서의 CaO 측면에서는 고온용, 내화용, 제진용 합금의 개발을 비용 절감측면을 강조하여 기술하였다. 물론 본 자료에서 Eco-Mg의 모든 측면들을 다루지는 않았다. Eco-Mg는 지금까지 개발된 것 보다는 앞으로 이루어내야 할 것들이 훨씬 많고 중요하다. 연구개발 뿐만 아니라 상업적 제품 개발에 대한 국내외적인 협력이 이루어져야 할 것이다.

  • "The engineering education program for environmental intention and value creation" has been executed from 2008 to 2010 in Suzuka National College of Technology, which program was promoted as "Good Practice for Education" by Ministry of Education, Culture, Sports, Science and Technology Japan. "Eco-car project" is one of these practical ecology/environment education programs. The project's members have been learning and researching the environmental managements by the process of design, manufacturing, and assembly of solar car, highly effective fuel consumption car (Eco-run car), electric vehicle and fuel-cell car. Also this project was supported by some professional experts of the local industries and community. The students learned the actual industrial technique, the engineering management and the structure of local industries by this project. In this paper, the environmental intention engineering design education with local industry collaboration is introduced.

  • Metal bipolar plate applied to Polymer Electrolyte Membrane Fuel Cell is getting most attractive due to their good feasibility of mass production and low cost. But it is one of the immediate causes of performance decline because it is difficult to reduce channel pitch of metal bipolar plate. In this study, mesh was inserted in between bipolar plate and GDL to obtain uniform contact pressure without reducing channel pitch. The section measuring and performance test were carried out to confirm the mesh structure distributes contact pressure equally in reacting area. The performance of 3 type mesh structures developed in this study were higher than the normal cell at all over the current range. Especially, it showed that the mesh cell performance was increased and pressure drop was decreased with diminishing mesh gap size. The Mesh structure was more sensitive to humidification and contact pressure change than the normal cell.

  • D. J. Haraway's cyber-feminism and Kim Seon Hee's eco-feminism are so different in the perspective of the modern scientific technology. While cyber-feminism thinks the outcome of the modern scientific technology positively, eco-feminism criticizes the totalitarianism and the human negation which the modern scientific technology gives rise to. Cyber-feminism gives us an image of the future female, but exposes an easygoing way of thinking of the modern scientific technology. On the other hand eco-feminism takes notice of the risk, that the modern scientific technology can be abused by the power of the minority, but fails in overcoming of the traditional view of female.
