최근 항만 물류 처리를 위한 EDI(Electronic Data Interchange) 문서 처리가 급증하여 이의 처리 시스템 사용이 증가하고 있다. 그러나, 기존의 시스템은 EDI 문서를 스크립트 방식으로 처리하였으나, 스크립트 작성이 복잡하고, 문서 처리 효율이 낮아 사용량 증가에 따른 처리 수요를 따라가지 못하고 있다. 이에, 본 논문은 스크립트 방식을 바이너리 방식으로 바꾸어 처리하는 시스템을 설계 및 구현하였다. 또한 항만 물류에 사용되는 12종의 EDI 문서를 개발하였다. 이에 따라, 기존 방식에 비해 문서 처리 속도가 약 12배 정도 개선되어 항만 물류 EDI 문서 처리 시스템에 활용될 수 있을 것으로 기대된다.

Recently, high luminance and high efficiency were realized in OLEDs with multilayer structure including emitting materials such as metal-chelate complexes. New luminescent materials, [2- (2-hydroxyphenyl)-quinoline] (Zn(HPB)q), [(1,10-phenanthroline)- (8-hydroxyquinoline)] Zn(Phen)q was synthesized. Zn-Complexes have low molecular compound and thermal stability. The ionization potential(IP) and electron affinity(EA) of Zn-complexes were measured by cyclic-voltammetry(CV). The fundamental structure of the OLEDs was $ITO/{\alpha}$-NPD/Zn-Complex/Al and then we made device structure rightly in energy band gap. We using Zn(Phen)q as emitting layer and Zn(HPB)q as electron transport layer. We measured current density-voltage, luminance-voltage characteristics.

The Korean railroads' logistics are facing the important turning points by the connection of. South and North Korean railroads, and the commercial opening of the High Speed Rail. These two factors demand several plans for the development of railroads' logistics, in which intermodal transportation with the others modes is wholly studied. In this respect the case of port of Hamburg, Germany, where railroads are completely integrated in the port, will permit the Koreans some useful lessons for the future of railroads' logistics.

East Asia has played an important role in the economic and social development in the Asian pacific region and in the global arena. In the region the impact of companies centralizing their logistics activities around a few distribution centers has already led some leading ports such as Singapore, Hong Kong to transform and expand their functions and business activities to provide port users with value added logistics services. Other ports in the region also have an important part to play in the total logistics Chain. In these environments, the maritime activities of Jang BoGo, who was the maritime king of the commercial maritime empire in East Asia in the 9th century, give many implications to the international logistics network strategy that Korea has to take in order to become a power of International Logistics. Though the trading and economic environments at that time may be quite different from today, the super-national maritime management pattern that Jang Bo-go, founder of the Northeast Asian maritime trading kingdom devised, gives us many implications in the global trading and economic environments, in the respects of overseas direct investment and international logistics. Accordingly, the paper aims to examine the establishment of hub port in Northeast Asia, modelled after the maritime network management strategy of Jang BoGo.

This study aimed to identify new routes for transporting automobiles from Korea to Mongolia by comparing them with the existing route. At present, a route from the Incheon Port through the Tianjin Port to Zamiin-Uud is commonly used to transport containerized cargo from Korea to Mongolia. This study examined five possible logistics routes from Korea to Mongolia using a time/cost-distance methodology based on real data. Through consecutive discussions with importers and freight forwarders in Mongolia, the potential routes were selected and costs, distance, and lead time were evaluated to provide additional route options for automobile logistics from Korea to Mongolia. The results indicated that each route could be ranked in terms of the total cost while the lead time for all options in the present COVID-19 period is 2 - 4 months, with no difference among the routes. In addition, although the confidence index of all routes was not impressive, route 3 was the most preferred option, followed by route 1. However, the study results cannot provide the answer to the question of "which route is more attractive for transporting automobiles from Korea to Mongolia." This limitation notwithstanding, this study provides real information on the critical factors of distance, cost, and lead time in terms of the selected transportation routes so that importers and exporters can compare the routes in terms of the priority of each factor in uncertain logistics environment.

In this research we present a new model, PLCM(Cort-Logistics Chain Management), which can cooperate each other in the port-logistic industry that occupy a heavy rain in the Northeast Asian economy. PLCM(Port-Logistics Chain Management) synthetically manages the logistic chain and information laying stress on the port. Unlike SCM, which hat a vertical relationship between the main groups to cooperate each other, PLCM has a horizontal relationchip between the ports to achieve common purpose and to improve their whole competitive power. In this research we present a concept of PLCM and a specific plan to develop a system for PLCM targetting Pusan, Shanghai, and Tokyo Port which occupy a heavy rain in the Northeast Asian port industry. This system is composed of integrated information system and EDI document exchange system according to the special quality of user's request information. And in order to prove its feasibility and validity, the case study sailing from Shanghai to Busan has been applied to this study.

First we provide an overview of how virtual enterprise works, including the lifecycle of a virtual enterprise, expected benefits from a virtual enterprise, and various types of collaborative networks. Next we focus on a problem encountered in the port logistics industry and suggest that implementation of a virtual enterprise can be a good solution to the problem. Then we suggest a prototype of the virtual enterprise in the port logistics industry and a freight transportation process as a business process in the prototype. And then we introduce major functions of the business process management system (BPMS) which, in general, can be regarded as a tool to create the virtual enterprise. Finally by adopting a specific BPMS, we illustrate how to design and implement the freight transportation process in the prototype.

This paper aims to investigate the time-varying systematic risk of the stocks of Korean logistics firms. For this purpose, the period from January 1991 to October 2016 was examined with respect to 21 logistics companies that are listed on the Korea Exchange. The systematic risk of the logistics stocks is measured in terms of the Capital Asset Pricing Model (CAPM) beta for which the sensitivity of a stock is compared to the return changes of the whole market. Overall, the betas of the stocks of the Korean logistics companies are significantly lower than those of the market unity; however, it was revealed that the logistics betas are not constant, but are actually time-varying according to different economic regimes, which is consistent with the previous empirical findings. This finding is robust across different measurements of the logistics betas. In addition, the impact of macroeconomic factors on the logistics betas was examined. The present study shows that the logistics betas are positively associated with foreign exchange-rate changes.

Ninety percent of an average Chinese manufacturer's time spent is on logistics. Therefore, logistics presents the greatest challenge for multinational companies conducting businesses in China. Although more than 18,000 registered logistics companies exist in China, 85 percent of their revenues are generated from basic trucking and storage services. These facts indicate that China will need increasing presence of high-quality foreign 3PL providers, who are able to provide sophisticated IT systems, industry/operational expertise, standardized operating processes, and international networks, compared to their Chinese counterparts. However, they are facing complicated array of laws and regulations as well as difficulty of finding qualified people to fulfill these needs. There are a number of foreign 3PL providers engaged in China's logistics sector to reap a huge opportunity. Nevertheless, many 3PL foreign providers are still cautious about making large investments. Thus they arelooking for alliances that can provide complementarities instead. Another salient feature of strategy is to take over the transportation assets and warehousing of major Chinese manufacturers and distributors.

본 연구의 목적은 한국 내 주요 항만별 선박출항현황을 비교 분석하는데 있다. 이를 위해 통계청 국가통계포털 "교통·물류 ⇨ 항만별 선박출항현황"에서 필요한 자료를 수집하였다. 분석기간은 2009년 1월부터 2020년 9월까지 총 141개월이다. 상승률 분석에서 2009년 1월 기준으로 여수, 평택당진, 광양, 부산, 인천, 울산 순으로 높게 나타났다. 변동률 분석에서 여수는 홀로 상승세를 보인 반면 다른 항만들은 완만한 하락세를 보이고 있다. 스캐터(Scatter) 분석에서 총 선박출항에 대해 여수를 제외하고 대부분 높은 수준의 동조화현상이 나타났다. 실증분석결과 최근 국내 선박출항 총톤수의 추세가 0% 이하에서 서서히 하락하고 있어 당분간 지금의 감소세가 더 이어질 것으로 예상된다. 향후 중국을 비롯하여 아세안 중심의 남방물류와 유라시아의 북방물류가 활성화되면서 주요 항만들의 역할이 더욱 확대되기를 기대해 본다. 각 항만별로 차별화된 물류서비스 개발과 선발출항 및 물류향상 요인을 도출하여 물동량 증대를 위한 유익한 방안을 찾아야 할 것이다.
