The purpose of this study is to establish common indicators that constitute a "low-carbon green city" and determine their priorities from the perspective of Incheon Metropolitan City with a view to help develop its climate change strategy strategic city. Several major cities, domestic and overseas, were benchmarked to come up with preliminary indicators consisting of six areas, twenty two planning factors, and 74 indicators. In order to evaluate the validity and relevance of preliminary indicators, expert FGI (Focus Group Interview) was conducted that changed the numbers of final indicators to six areas, twenty two planning factors, and 82 indicators. Finally, AHP (Analytic Hierarchy Process) was conducted to assign relative importance (i.e. weights) to each indicator. Through the layering process of AHP, the upper category of "field" and lower category of "planning factors" were set up as policy prerequisites for constructing a low-carbon green city (6 fields, 22 planning factors). The AHP results for the first level (fields), green city space was ranked first, followed by energy and resource circulation, green traffic, ecological preservation, green logistics, and governance. Among all planning factors, land use, energy efficiency, traffic system improvement, location planning, securing of ecological area, efficiency of logistics, and cooperative organization showed the highest priorities.

조선 및 해운·물류 분야의 디지털 전환은 자율운항선박의 도입 및 선박의 운항방식의 변화를 이끌 것으로 예상된다. 기존 운항방식과 함께 자율운항, 원격운항 등 다양한 운항형태가 공존하며, 선박 운용 프로세스의 전환과 새로운 이해관계자의 등장이 전망된다. 본 논문에서는 선박 운항방식 변화에 따른 미래 선박 운항 프로세스를 분석하고, 미래 선박의 운항환경 변화를 예측하여 주요 업무별·이해관계자별 기능요건을 도출하고자 한다. 델파이 기법을 활용하여 항해 및 화물운송 계획 수립단계부터 최종 목적항 입항 및 화물 하역단계까지 선박 운항 시나리오를 구성하고, 업무별, 수행 주체별 미래 업무 변화를 예측했다. 원격운항, 자율운항 등으로 선원의 개입이 최소화될 것이며, 각 분야의 전문가가 선박 운항의 다양한 측면에서 책임과 의무를 갖게 될 것으로 예상된다.

In this paper, we compare and analyze the current state of the productivity of the stevedoring work among several container terminals in 1999. Based on these results of analysis, we firstly classify several factors which impede the efficient operations of container terminal as follows ; late arrival of container beyond cargo closing time(CCT), change of port of destination, change of vessel, and return cargo. Such factors are major cause for the cargo rehandling on terminals, thus deteriorate the overall performance of transfer crane during the stevedoring work. In order to improve the productivity of container terminal, we suggest that it is necessary for establishing and operating the efficient logistics management system. Especially, we emphasize the importance of information exchange on the scheduled cargoes among the relevant parties such as shippers, shipping companies, and terminal operators, which is the most effective way to alleviate the cargo rehandling.

In this paper, effects of information sharing in multi-level supply chain management have been studied through simulation. The simulation model consists of a manufacturing company as a center, three suppliers, two logistic centers, and three different retail supply lines of each logistics centers. The mathematical model and the simulation were developed when real-time information sharing occurs and does not occur in supply chain under the assumption that each company applies (s, S) inventory policies. In addition, this paper analyzed the effects of the change of variables related to total costs, which compose of total ordering cost, total transportation cost, total carrying cost and shortage cost that are caused by the change of demand of three different patterns with the way of information sharing.

The increasing global average temperature and the emergence of various abnormal climate phenomena are already being experienced in reality. The problems arising from climate change are expanding and becoming catastrophic, despite the efforts of various organizations to prevent them. In order to avoid climate issues from becoming black elephants, we conducted interviews with emergency planning officer from various institutions to identify potential X-events caused by climate change. The results of analyzing the anticipated X-events by these emergency planning officer revealed a chain of ripple effects associated with their occurrence. This implies that once an X-event happens, its influence is broader and more significant. Through this study, we aim to share the understanding of the ripple effects of climate X-events with many people, raising awareness of the severity of climate issues. We hope that this will serve as a starting point for more institutions, individuals, and nations to make efforts in resolving climate problems, turning X-events into opportunities rather than crises.

선박이 대형화되고 경제규모가 커지면서 선박의 화물운송 규모도 매우 커지고 있다. 이에 따라 컨테이너 터미널에서는 안벽하역 장비의 고속화, 대형화를 추진하고 있으며, 안벽의 고속 생산성은 한정된 규모의 장치장 점유율에 영향을 마치게 된다. 본 연구에서는 OHBC, RMGC, RTTC 등의 장비제원과 배치에 따른 장치장 점유율을 산정한다.

Purpose -This study is to measure the effects of retail legislations on small retailers and traditional markets. Research Design, Data, and Methodology - The authors have developed a questionnaire with five hypotheses on the basis of previous research results and six constructs: the improvement of sales volume, the number of customers, the improvement of store traffic, the increase of store staff, business expansion and retail regulation. Furthermore, the research has adopted a five-point Likert-scale technique. In order to increase research reliability as well as validity, the authors have adopted a few different research techniques such as exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Results - Although existing retail regulations might be better than nothing for now, the degree of retail constraints on large retailers should be strengthened. Furthermore, different legal methods to protect mom and pops are needed. Conclusions - In order to improve the effects of retail restrictions on large retailers, the research indicates that the central government should change a retail policy, that is, introduce new technical ways to keep mom and pops and conventional markets.

The management strategies of each company has been changed fundamentally owing to the emergence of digital economics by using internet. Therefore the efficient management of global e-port causes the main issues not only effect the survival and growth of ports but also exert new opportunities and fatal threats on them. Under the circumstances of these change, the Kwangyang port have to introduce e-biz for the purpose of increasing the level of their competition. The focus of this article is to suggest some strategies on the implementation of Kwangyang Global e-port in Korea. To analyse the e-port realities, I first reviewed the trends of e-marketing and e-biz. I chose and analysed website of four ports like Hongkong, Singapore, Antwerp and Hamburg as successful global e-port models. This article is focused to suggest the theoretical background by analysing the strategic points of Kwangyang global e-port which are divided in 6C: Contents, Communities, Connection, Commerce, Communication and Customization. This paper analyses many problems of Gwangyang port and presents various develpment ways to activate Gwangyang port. In order to be a global e-port, first of all Gwangyang port must improve global web-site by 6C. And also Gwangyang port have to constitute logistics hub site, create infrastructure needed to run electronic business more easily over the internet, establish nationwide network of industries, build up marine and port logistics information system.

The medium and small logistic companies that have an outsourcing contract from the large corporation are encountered with a problem to introduce the ERP system to their current business environment due to following risk of change in current business environment, high cost involved in investment, and lack of understanding of business requirement of ERP. Instead of build their own ERP system, the small and medium logistic companies are using the large corporation's ERP system and get the benefit of efficiency in management and control process. Therefore, it is more like the organization hierarchy, not collaboration between the medium and small companies with the large corporation. In this study, the survey method to find out how the medium and small logistic companies understand the importance of ERP system on continuous growth of business by AHP. as result, they are recognized. The benefit of the ERP system as having much effect on business competitiveness.
