미국을 비롯한 전 세계 국가는 드론을 이용한 물류 서비스의 상용화를 위해 활발한 연구를 진행하고 있다. 국내에서도 물류 배송 기업을 비롯하여 이동통신사에서도 드론 물류 배송 서비스의 연구, 개발을 진행 중이다. 그러나 우리나라와 미국은 last-mile 물류 배송 환경이 다르다. 우리나라는 인구의 77% 이상이 아파트 등의 공동주택에 살고 있으며 인구 밀도가 전 세계 4위에 달하는 나라이다. 이에 따라 드론 물류 배송에 있어 우리나라 환경에 맞는 연구가 필요하다. 본 연구에서는 도시 지역에서의 근거리 무선통신과 기압계를 활용한 드론 물류 배송의 정밀 위치 판단의 방법을 제안한다. 실험 결과 제안하는 방법을 통해 2.5m 이내의 창문도 탐지할 수 있음을 확인하였다. 본 연구에서 제안하는 방법을 통해 도심에서의 드론 물류 배송 기술의 향상에 도움이 되길 기대한다.

The Korean Ministry of Environment and Daegu Metropolitan City are establishing the Korea Water Cluster, which will focus on promoting and escalating Korean water industries. The water industry, a future-oriented and promising business sector, is continuously growing each year worldwide, so the project is very timely. In reality, however, challenges still need to be addressed, such as accessibility, logistics systems, social infrastructures, and attracting good companies. For the Korea Water Cluster to be successful, those issues should be solved, but it is difficult to untangle the matters only with efforts of the Korean Ministry of Environment and Daegu Metropolitan City since some issues will require a great deal of both money and time. Therefore, it is important for the Korean federal government to administer support and finances for certain parts of the project, and for the Korean Ministry of Environment and Daegu Metropolitan City to take on other issues to ensure the Korea Water Cluster is successful long-term. The success of the Korea Water Cluster project will result in the Korea Water Cluster becoming a global hub for the future water industries.

연안해운과 관련한 최근 환경 변화는 남북해운합의서 발효에 따른 남북물류의 증대 가능성과 환황해권, 환동해권의 동북아 연안 부상 등을 언급할 수 있다. 그러니, 연안해운에 대한 국가 정책의 소외는 우리나라라 물류거점화 되는데 많은 문세점을 노출하고 있다. 이러한 문제점을 해소하고 외항과 연안간 균형발전을 도모하여 우리나라가 동북아 물류거점화 할 수 있는 방안을 크게 연계수송체제의 강화. 연안해운의 체질강화 및 정부의 체계적인 지원정책으로 구분, 제시하는 것이 본 연구의 목적이다. 연구결과에 의하면, 첫째로, 연계수송체계를 강화하기 위해 거점항만내에 연안피더 전용선석의 구축으로 연안피더운송의 연계성 강화가 필요하며 둘째로, 언안부두에 화주즐 유인할 수 있는 공동장치장 및 하역설비를 대폭 보강하여 일괄 서비스체제의 확립, 노후 비경계선의 Ro-Ro 선 혹은 고속컨테이너선으로의 대체. 화물선에 대한 면세유 공급과 각종 세제의 실질적인 혜댁부여로 환경 친화적이며 균형있는 외항-연안 물류사슬체계(Logistics Chain System)를 갖추는 것이 필요한 것으로 나타나고 있다.

포스트교토체제로 지구온난화를 불러오는 온실가스의 배출량을 줄이는 노력이 세계적으로 확산되고 있다. 물류분야의 환경부하 문제를 해결하기 위해서는 유통 각 단계에서 상품과 서비스에 대한 노력과 함께 환경친화적 활동이 이루어져야 한다. 본 연구에서는 기업의 환경물류활동 중에서 수송과 포장 기능에서 발생하는 이산화탄소 배출과 폐기물에 영향을 미치는 활동에 대하여 전략, 수 배송, 보관, 하역, 포장, 정보로 나누어 설문항목을 작성하여 기업의 매출 규모별 추진실태와 그 수준을 파악하였다. 144사를 대상으로 54개 항목에 대하여 조사하였으며, 이를 바탕으로 우리나라 기업들이 추진하여야 할 환경친화적 물류활동의 추진방향을 제시하였다.

Home appliances go through a couple of packaging stages from the plant to consumers. The primary packaging, inner packaging for each part, happens for protection after products leave the plant. The secondary packaging happens in the unit of product, ensuring cushioning packaging to protect products from movement. The final tertiary packaging is for transportation and delivery. Each stage of product packaging, however, costs a lot of money because of disposable packaging materials used in each stage including vinyl, tapes, Styrofoam, and corrugated cardboards. Discarded packaging materials also cause environmental problems. In an effort to come up with a measure to solve those problems, this study proposed a plan to minimize logistics costs with semi-permanent packaging materials to replace disposable ones including Styrofoam, vinyl, and corrugated cardboards in the stages of inner packaging, cushioning packaging, product unit-based packaging, and transportation. The study also developed a model to cut down logistics costs by reducing various packaging stages including the primary, secondary, and tertiary stage only to the secondary one through module-type products instead of the transportation- and delivery-type ones, as well as demonstrated the excellence of the study through numerical analysis.

Purpose: The industrial sector, especially in developed countries, is seen as the primary threat to sustainability. As a result, contemporary organizations prioritize establishing sustainable business practices. This sustainability can be achieved by organizations being concerned with their external environments, which is referred to as going green. This study aims to provide a green logistics network design to explain how to attract green consumers. Research design, data and methodology: This study conducted a comprehensive process to obtain textual dataset in the current literature and finally the author could collect total 26 relevant prior studies to achieve the purpose of the study. All dataset was thoroughly screened and selected for the high-degree of validity. Results: Based on the intensive literature review, the author insists that the four findings presented in this study will be useful as they provide evidence of the importance of technology in achieving global sustainability.in the situation we face that technology has become an important part of human life. Conclusions: This study provides meaningful insights into the environmental strategies that organizations across the world can implement to achieve a green supply chain based on the solutions in this study. The strategies presented in this study are evidence-based and have been tested through different studies.

The lorry based transportation system in korea has many problems such as high domestic logistic cost, environment pollution and road damage etc. Hereupon, the necessity of improvement for national logistics system has been proposed continuously. Therefore we carried out this research through AHP(Analytic Hierarchy Process) to measure relative importance between effect factors and constraint factors and examined the possibility of Modal Shift from lorry transportation to coastal transportation. As the results of this research, the relative priority on modal shift policy enforcement (0.556) is higher than that of maintenance of the present transportation system(0.444).

Recently, ordinary mail is decreasing continuously by the development of ICT (Information and Communications Technology) including E-mail, messenger service, and etc. On the contrary, parcel post is increasing by the increase of online shopping, home shopping, and etc. Aside from these changes, the demand for various mail acceptance and delivery means is increasing with the increase of single households and dual-income couples. To overcome these environmental changes, Korea Post installs unmanned post offices which are composed of various unmanned mail acceptance and delivery postal systems. In this paper, we propose the methodological approach for the site selection of unmanned post office among the existing post offices and the installation standard of unmanned postal system considering the operation cost by the mail volume.

The fundamental objects of the Korean Grand Canal (KGC) Project are the rehabilitation(or restoration) of river corridor ecology, improvement of river water quality, reduction of flood damages, countermeasure of the huge rise in energy price and the high discharge of $CO_2$ due to the vast use of energy for highway logistics. The other important objects, like an increase of water in the river channel, are to provide people with the pleasure of seeing the water and intimacy (touchiness) with it, an increase of flood controllability, effects of dilution of river pollutants, dredging out sedimentary pollutant from the river bottom, the function of infrastructure to pare down the logistics (distribution) costs, and the opportunity to expand tourism. These kinds of fundamental concepts must be evaluated as future values in Korea and elsewhere.

When the electrical appliances such as TVs and refrigerators become obsolete, they must be collected to the recycling centers to avoid environmental damages. The obsolete home appliances are first moved to the regional collection point; and then transported to one of the recycling centers. Each recycling center has a limited capacity; and some recycling centers can process only certain types of products. For given locations of the existing collection points and recycling centers, optimally assigning the obsolete home appliances of each type from each collection point to the recycling centers can significantly reduce the total transportation cost. We formulate this problem as an LP problem. We also present an approach to determine the locations of additional recycling centers in order to alleviate the over-utilization of the current recycling centers.
