  • The leachate recirculation anaerobic digestion system has the advantage of stable methane gas generation compared with existing one phase systems. In this study, an anaerobic digestion system fed with source separated food waste from school cafeteria was studied with different food waste/inoculum anaerobic sludge volume ratios (8:2, 3:7, 2:8). From this study, leachate recirculation anaerobic reactor with food waste/inoculum anaerobic sludge volume ratio of 2:8 that is 9 gVS/L of OLR(Organic Loading Rate) had the highest gas production. Also this anaerobic reactor showed daily decrease of H2S and NH3 contents in produced gas. Average biogas yield was 1.395 m3 Biogas/kg VS added. Other anaerobic reactors with food waste/inoculum anaerobic sludge volume ratio of 8:2 and 3:7 stopped methane gas production.

  • 물류업계는 배차 운송하기 위한 많은 알고리즘, 차량경로문제, 차량일정계획, GIS, GPS 등의 여러 연구를 진행하고 있다. 하지만 물류시장에 배송물량은 늘어나지만 배송을 하기 위한 차량과 기사는 한정되어 있으며 다단계 거래구조로 인해 수수료가 발생하여 최말단에 있는 화물차주만 수익이 감소한다. 이런 문제에 의해 차량주인(차주)는 운송장소와 운송비에 중점을 두고 배송 건을 선택하여 운송을 하고 있다. 본 논문에서는 이러한 물류기업의 배차문제와 차주 운임비 문제 해결을 위하여 운송비 기반배차 시스템의 정보화를 실현하기 위한 기초적인 데이터 구조를 제안하고, 운송비 중심의 배차 알고리즘이 적용된 배차 시스템을 물류업체에 적용한 결과를 제시하였다.

  • In modern marketing environment, we are more interested in logistics as industrial structure is complicated and globalized. Most companies focus on reducing the cost price. So a lot of companies study on cost estimation logistics. However, it Is very difficult to estimate the cost of logistics. Thus they mainly use linear method such as the simple distance of transportation. This study defines the cost of logistics, structure & network of military logistics and proposes the costing estimation model in the logistics. We apply to battle shoes which are the main clothing in the military. In the result, we found some differences on the rate of cost structure between military and civil companies. This study can be used directly to the decision making for optimal military logistics alternatives and contribute to the efficient operation of military budget.

  • 우리나라 상품의 대외경쟁력은 대체적으로 국내 물류비에서 결정된다. 이 좁은 국토(거리상으로)에서 왜 그리도 많은 내륙 물류비를 부담해야 하는 지 많은 이들이 의아해 한다. 제대로 갖추어져 있지 못한 국가차원의 사회간접자본(SOC) 시설, 승용차 중심의 도로운송시스템도 문제지만 제품공장과 수출입관문인 항만.공항간의 연결점에 있는 물류거점시설들이 활성화돼 있지 않다는 것이 요인으로 지적되고 있다. 민간업자 차원에서는 국토 요소요소에 물류센타를 세워놓고 고객들의 화물에 대한 일괄 물류서비스를 제공하려고 많은 노력들을 하고 있다. 이곳에서는 보관, 재고관리, 유통가공, 보세운송, 수배송, 물류대행, 물류컨설팅 등 종합(통합) 물류서비스들이 이루어진다. 이에 본 연구에서는 이러한 물류센터의 실태를 조사하여 수요에 따른 물류센터의 공급능력을 평가하면서 물류의 일괄서비스 측면에서의 효율성을 점검해 보고져 한다. 또한 향후 이 분야에 있는 연구나 조사 필요성이 있는 과제가 무엇인지를 검토하여 단계별 연구과제를 정의하여 체계적인 연구가 진행될 수 있도록 하는데 그 믿걸음이 되고져 한다.

  • Korea has operated the export support system of agricultural products for export expansion of agricultural products. Export logistics expenses support program in the export support system is accounted for the largest share. Export logistics expenses support program is, including the export industry promotion of agricultural sector, also in domestic agricultural price stabilization is evaluated to have contributed. However, recently, in a changing Korean International Agricultural Environment, depending on whether the classification of developing countries, so it is displayed differently. If you are classified as developing countries, continued support of export subsidies, which has been promoted to the export sector of agricultural products can be up to a certain period of time. However, if it is not included in the developing countries, support of export logistics costs of agricultural products is abolished. In this study, export logistics cost support in the export sector of agricultural products by analyzing the effect on exports, WTO/DDA agriculture negotiations result, presenting a proposal that is in preparation for the reduction and elimination of export logistics costs to be expected.

  • The increase of international and domestic trade according to global industrialization and economic growth has raised the national logistic cost in connection with physical distribution of articles. In order to reduce these costs and rise up national industrial competitiveness, Korea has also tried to improve the efficiency of logistics with various methods as advanced countries did. Especially, Korea government has decided standard dimension of pallets with T11 ($1100{\times}1100mm$) on the basis of unit load system in early 2000s, and certification program for logistics equipments has been operated to keep up the compatibility for the equipments and packaging with modulation of T11. Consequently, this certification program has contributed to extend standardization for logistics and to grow up 3 party logistics, but compared with advanced countries, the rate of national logistics cost to GDP (gross domestic product) still shows about 3% gap as demands for certification have been decreased in the recent. In this study, therefore, we proposed the development of logistics certification system based on social needs as a policy device to activate logistic industry as well as improve the efficiency of national logistics after we had analyzed all of certification programs for logistics being run in Korea. Namely, the first is the development of certification project for Northeast Asia's logistics corresponding to necessity for applying returnable transport system according to increasing the amount of trade between Northeast Asia's countries. The second is the development of certification project for safe transportation of packaging corresponding to costumer's needs for safe transit according to the growth of electronic commerce and the increase of global distribution.
