우리 사회는 COVID-19로 인하여 비대면 사회로 빠르게 변화하고 있다. 특히, COVID-19에 대한 대응으로 인플레이션 부작용이 나타나고 있는데 공급망 붕괴가 원인으로 지목되고 있다. 물류를 안전하고 원활하게 하려면 선박검사에 비대면 기술이 요구되는데 AR과 VR 기술을 활용한 원격 선박검사 시스템이 필요할 것으로 전망된다. 이에 따라, 본연구는 산업과 연구의 실무에서 요구하는 기능에 대한 설문조사를 기반으로 분석하고 기술개발과 시스템 설계에 대한 방향성을 제시하고자 한다.

Busan port has played a part as the main trade gateway in Korea for several decades. However, due to the rapid integration of China into the global economy and the grand changes in global trade structures, the trade gateway system in Korea and the status of Busan port have been transformed. Busan port's role as a trade gateway toward Japan and U.S. has increased during last two decades but, in cases of China, its importance has relatively decreased. Moreover, Busan port's competitiveness has been undermined in the most part of commodity trade. These phenomena reflect the high competition among trade ports which tend to increase the effectiveness of supply chains. Based on the geographical research tradition which has understood a port as a nexus between hinterland and foreland, this study focuses the changes in characteristics of trade freights and the status as a gateway of Busan port. This approach will contribute to the understandings of dynamics in the comtemporary international logistics.

As competition in domestic and overseas ports intensify, new and small domestic ports are realizing certain limitations to independently secure competitiveness. This study collected data over 60 months with five modifications for container and general cargo volume around Gyeongin Port. Short-period (12 months) cargo volume was forecasted, which revealed the need for a middle-to-long-term development plan. First, the hinterland logistics complex of Gyeongin Port is expected to contribute to the coastal maritime facility through the quasi-public system for fishery product transportation and passenger services. It proposes to achieve this by opening channels to and from China for precision machinery, home network systems, LEDs, and machine industry items. second, specializing the ultra-light cargo transport route, and connecting the coastal island areas of the 5 West Sea Islands to Ara Waterway (Integrated Fishery Product Center of the 5 West Sea Islands). Third, on the basis of organic cooperation of government? local government ? port, the incentive and pre-circular support system would be required, and lastly, it shall carry out the adjustment of functions in nearby ports and specialization strategy simultaneously through the integrated operation of the ports in the capital areas.

This research is focused on the organizations related to development and operation of automated container terminal to find the core factors to prepare for the changes in maritime logistics circumstances and to secure superiority in the middle of fierce competition. Through an analysis of the status of development and operation of internal and external automated container terminals, it is concluded that public organizations, companies, research centers/schools, and private organizations influence on the development and operation of automated container terminals. The specific role of each organization is also concluded in this study. Based on the findings above, a survey of experts in the organizations of container terminals in Korea has been carried out using AHP method. Through this survey, the order of importance of the related organizations was found to be public organizations, research centers/schools, companies, and private organizations. This research can be referred to make a master plan for the development and operation of automated container terminal in Korea.

In the paper, we design a autonomous mobile robot for freight transportation and propose an operation method of the robot in the warehouse. In order to implement autonomous navigation, it is needed to recognize the position of the robot and track the path to the target. Previous methods are hard to change the workspace environment and need high cost to install and keep a maintenance of the system. The lifter of freight transportation robot is designed to load and unload a baggage through up and down motion. Also, ultrasonic sensor, RFID, QR-code and camera sensor is used to carry out various functions while the robot navigates in the various environment. We design an operation method of the mobile robot in order to effectively arrive a goal position and transport a freight. The proposed methods are verified through various experiments.

CSD is IEEE Stan없rd 802.15.4b based Container Security Device which is proposed by the U.S Department of Home Security. It is mounted inside the container to sense opening of the container door. ConTracer is the CSD which is developed in this research whose major features are sensing door opening status as well as history inquiring on internal environment and shock to the container by mounting the temperature/humidity/shock sensors. Moreover, its RFID frequency bandwidth uses 2.4GHz 10 correspond actively to the radio regulations used by different countries. This. paper introduces the development trend of CSD, compares the ConTracer which is developed thru this research and other company's CSD, and introduces CSD System which is designed and established using ConTracer. Finally, the implemented CSD System is verified by applying the demonstration service to container distribution between Korea and Japan.

Deepening of the global competitive environment due to changes in operating environment and business, domestic and abroad companies in automotive industry are trying to optimize their production and logistics, to enhance their supply chain competitiveness and to promote information strategic planning to maximize their IT-enabled capabilities. In particular, the automotive industry is showing the various efforts to build the demand-based production system for responding to the market changes and preparing the global production and sales system. Despite of their various effors, the IT deployment and utilization levels of parts suppliers in the field of production/logistics companies are shown as higher in comparison with other area supplies, but the levels are shown as a very low condition compared to the parts suppliers of other manufacturing sectors. In this sense, the subject of this study, 'A' company (SMEs), has the challenges for improving the IS utilization and the accuracy of the information system according to the inefficiency of manual and field validation. Consequently, to improve and enhance the utilization of information systems, A company is carrying out the project to improve the ERP and POP operations by in-house approach, but they have shown the limitation in introducing and applying the latest technology.

The purpose of this paper is to clarify the distribution system and the spatial characteristics of sales for the internet shopping mall on the basis of its off-line presence. The distribution system of this internet shopping mall is divided into the goods selection process and the product delivery process to consumers according to the function and role of the distribution center which is performed by cooperative companies. The internet shopping mall uses a different distribution system from the off-line department store, outsourcing the delivery process to door-to-door delivery companies in order to reduce costs and to increase the speed of delivery. Sales in the internet shopping mall are concentrated in the delivery unit area where the main office is located. Accordingly, in the case of the internet shopping mall based on an off-line presence, the mail-order business does not fully overcome the limitations arising from space. Also, the main factors influencing the value of sales, according to the area, are the number of women aged 20 to 49 and the distances involved.

Recently fast innovation of Internet technology causes lot of application to change into web application and requirement for the inter-operable communication among various systems are increased rapidly. These trends are part of changes which is caused by ubiquitous world and it is just beginning of huge waves that is required to fit and change under the ubiquitous environments. This thesis is focused on the Design and Implementation of Layer Structured Components which can be interfaced effectively for the Material Management System under the Heterogeneous Client Server Environments. The key points to do that kinds of affairs are using XML web services that can communicate thru systems and also using independent layered components for the enforcement of reusability and inter-operability. For the various type of testing of implementation, we used RFID System, PDA, Desktop Systems and confirmed the normal operation without concerning the type of client system and platforms. The Components proposed in this thesis could be reused effectively in case of developing similar applications.
