  • RFID system the key technology of ubiquitous era, has been emphasized in logistics. Logistic enterprises are required to apply RFID systems considering their investment costs, actual effectiveness, operational satisfaction and so on. For such a purpose, many applicable methods of RFID system have been developed A method that RFID tags are directly attached to products or pallets is utilized in most cases. However, this method requires expensive investment cost, frequent replacement of damaged tags for the small and medium (SM) third party logistics. In this paper, we analyze statistically the current status and requirements of SM third party logistics. Based on their requirements, we propose the realtime warehousing-delivery management by the method to attach a RFID tag to each warehouse rack, together with the economy analysis index in order to evaluate economical efficiency. Consequently, this method is expected to reduce Investment cost and to improve operational effectiveness and satisfaction.

  • This study investigates the main trend of LOHAS, examines and analyzes the LOHAS marketing cases of the fashion industry, and proposes an effective LOHAS marketing strategy for the domestic fashion market. Data were collected from Naver, Google and Daum from 2005 (when LOHAS began to be recognized) to October $31^{st}$ 2010. We searched the research material with keywords related to the research subject (such as eco, green, well being, echo-friendly, LOHAS, sustainable, environmental management, and green management) to conduct a theoretical and exploratory study through qualitative analysis. The data are analyzed with three types such as personal value of eco-friendly fabric, economical value of recycled fabric and re-use or re-form, and social-ethical value of distribution and promotion. The research results show that LOHAS marketing activities focused on personal values and social-ethical values (rather than economical value) and from an eco-friendly management centered on merchandise; in addition, an eco-friendly supply chain management incorporated with a management system were applied. LOHAS marketing strategies at home and abroad revealed some differences in the cases of eco-friendly fabric, recycling, and fair trade.

  • Because international environmental and energy problems such as global warming and ozone depletion, exhausting of fossil energy sources are more serious than before, renewable energy system is attracting people's attention more and more. Organic waste bioenergy system among a variety of renewable energy system is expected to have an effect on building a society which is eco-friendly and recycles resources owing to carbon neutral effects. So this is considered as the role of an energy source of the building. Previous studies on the organic waste bioenergy are mainly bioenergy technology and activation plan of the bioenergy supply. But the performance evaluation studies of bioenergy systems installed in buildings are rarely. This study is to evaluate applicability of the organic waste bioenergy system as the building energy supply system by energy and environmental, economical analysis.

  • 경량혼합토는 건설잔토나 준설토 및 현장에서 발생하는 점토나 실트질 흙을 사토처리 하지않고 현장에서 유용할 수 있는 매우 경제적이고 환경친화적인 재료이다. 최근에는 페자원(폐타이어가루, 왕겨)을 경량혼합토에 첨가하는 건설재료 재활용에 관한 연구가 진행 중에 있다. 본 연구에서는 경량혼합토를 제작하기 위해 필요한 배합설계변수인 원료토의 중량, 함수비 및 기포재와 첨가할 물의 양, 그리고 강도를 발현하기 위하여 필요한 고화재로서 시멘트첨가량에 대한 최적의 배합설계에 대한 분석을 하였다. 이를 위하여 일축압축시험에 의한 응력-변형 거동과 양생기간 및 성분비에 따른 강도분석, 폐기물 성분비에 대한 실험강도 비교분석을 수행하였다. 마지막으로, 합리적이고 경제적인 배합비 산출을 위하여 경량혼합토의 목표강도를 결정하고 최적의 배합설계 변수를 제시하였다.
