It is widely acknowledged that Chinese economy becomes a center of world economy and takes up a considerable portion of the trade in Northeastern Asia. Due to the investment and the logistics modernization strategy of Chinese government, recognizing the importance of logistics, the competitiveness of Chinese major ports is tending upward rapidly. Therefore, it is necessary to analyze the competitiveness of Chinese major ports in order to develop the logistics strategy of Korea by cooperating or competing with Chinese ports. In this study, we analyzed the competitiveness of 10 major Chinese ports with Data Envelopment Analysis(DEA). Through the analysis, we could investigate the efficiency of 10 major Chinese ports and figure out the trend of the efficiency within recent 10 years. In order for Korea to achieve the national strategic goal, becoming a logistics hub in East Asia, it is obvious to understand the competitiveness of Chinese major ports which are major competitor and strategic partner at the same time. This study will be useful to understand the competitiveness of Chinese ports and to develop a logistics hub strategy of Korea.

In general, furniture industry, with its high foreign dependency, has serious logistics issues that are commonly raised in such countries as Korea, China and Japan. This leads to my different possibilities & ways of rationalizing the logistics systems that utilize port hinterlands. Thus the purpose of the present paper is to create new logistics systems which will work effectively across the three countries. In this research study, we came up with 2 logistics models in which the port hinterland of Busan serves as the distribution center for furniture industry, and the models were suggested as the cooperative logistics business systems for the North-east asian region. In the proposed models, 'Busan furniture logistics center' has the dual functions of 'the cross-docking center from China to Japan' and 'the assembly & delivery center for furniture imported by Japan'. To have this logistics business center materialized, we propose that policy-level supports from the relevant port authorities be provided in the following three aspects: overseas investment promotion focused on the furniture industry of Japan, protection & enhancement of competitiveness for the port of Busan, and uilization plans for the new port hinterland of the city.

The purpose of this paper is to measure the productive efficiency and competitive strength of Regional Maritime Affairs and Fisheries Office using the DEA. Using EMS(Efficiency Measurement System) which is LP solver, quantifies in one way or another a "distance" to the efficient frontier of the technology. An input oriented measure quantifies the input reduction which is necessary to become efficient holding the output constant. Symmetrically, an output oriented measure quantifies the necessary to become efficient holding the inputs constant. A non-oriented measure quantifies necessary improvements when both inputs and outputs can be improved simultaneously. According to the analysis result of the DEA method, inefficient Regional Maritime Affairs and Fisheries Office should recommend benchmarking reference Regional Maritime Affairs and Fisheries Office in order to enhance the productive efficiency of port administration and a public institution. Besides data on productive efficiency serves as a tool for policy-makers at all levels of activity and is essential for improving the efficiency with which the various systems operate.

운송에 필요한 각종 서류와 정보의 효율적 교환은 국제물류시스템의 중요한 일부분이 되었다. 또한 EDI(전자문서교환)는 수출입에 필요한 각종 상거래 서식을 컴퓨터가 읽을 수 있는 표준화된 전자문서의 형태로 바꾸어 교환함으로써 무역절차의 간소화와 운송서류의 신속한 교환을 가능하게 하여 물류 효율성을 증대시키는 것으로 알려져있다. 이러한 맥락에서 세계각국의 항만당국은 자국의 물류혁신을 도모하기 위하여 경쟁력으로 EDI의 도입을 추진해왔다. 그러나 90년대에 들어 EDI의 발전은 처음의 기대와는 달리 저조한 것으로 나타났다. 이는 크게 두가지로 설명된다. 첫째는 EDI 문서의 국제표준을 제정하는 UN/ECE 산하 WP4의 표준제정 미 공표의 비효율성으로 인해 실제 상거래에서 필요한 문서들의 EDI 표준화가 제때에 이루어지지 않았다는 점이다. 두 번째 이유는 대부분의 EDI 사용자가 전자문서의 교환통로로 이용해 왔던 부가가치통신망(VAN)서비스의 고비용적인 구조로 인하여 비용에 민감한 중소규모 화주들의 폭넓은 이용을 저해왔다는 점이다. 따라서 본고에서는 EDI의 확산을 저해했던 두가지 문제점에 입각하여 먼저 효율적 EDI 표준 제공을 위한 국제적 노력의 산물인 CEFACT(Center for Facilitation of Procedures and practices for Administration Commerce and Transport))와 보다 안전하고 신뢰성 있는 전자상거래 솔류션의 마련을 위해 이루어진 각종 국제기구들의 활동 및 결과물들을 소개하고 다음으로 인터넷의 급속한 확산으로 새롭게 개발되고 있는 Web-based EDI, XML/EDI, Simpl-EDI, Form-based EDI 그리고 Lite-EDI의 저비용적 구조 측면을 분석하여 중소규모화주들의 EDI에 대한 인식을 제고시킴으로써 EDI의 전반적인 확산을 도모하고 있다.

Recently the trade patterns of the entire economy are rapidly changing on development of IT. The field of port logistics is enforcing a competitiveness through preliminary offer of information and a batch process for improving the structure of logistics management which is apparently high cost and the low efficiency since 1990. But a previous EDI is insufficient in process ability. Bemuse it costs for the purchasing and maintenance of the expensive communication devices which is operated on the VAN environment. A web based EDI operating on an open network environment is needed to improve these problems and to handle transaction efficiently among many and unauthorized personals. Therefore, this study is willing to present a new web based model of the pull process which extracts the data when the receiver is needed to improve the push process which is transmitting data unilaterally.

With increasing uncertainty of energy market in the world, the policies for the energy resource security have become crucial Several countries with poor energy resource like Netherlands and Singapore have pursued the policy for becoming an oil hub in the region. Singapore has been an oil hub in East Asia for a long time not only because it is well located with a large number of countries exporting and importing oil but it has also pursued strong policies to become an oil hub while establishing favourable institutional, regulatory and business environment for accommodating major refineries and petro-chemical companies. However with growing trading volume of petroleum products in Northeast Asia and a record high price of oil in these days, the necessities of another oil hub in the region are considered in order to reap benefits of the security of economical and stable oil. South Korea is situated astride the main North Pacific shipping route, with deep water ports and proximity to Chinese and Japanese industrial centres that make tank terminal operators Ideal choices for the oil hub in Northeast Asia although it has several disadvantages such as lack of independent storage facilities, underdeveloped oil trading market and unfavourable business friendly climates etc. This study is focused on examining the globalization strategies of tank terminal operators such as Vopak, Oiltanking and Odfjell in order to suggest the policy implications for becoming an oil tub in Northeast Asia.

Purpose: The extraction conditions for bioactive components from peanut shells, which is a byproduct of peanut processing, were optimized to enhance the total phenolic content (TPC, Y1), total flavonoid content (TFC, Y2), and 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity (RSA, Y3). In addition, this study evaluated the anti-obesity effect of peanut shell extract. Methods: Optimization of ultrasonic-assisted extraction (UAE) was performed using a response surface methodology. The independent variables applied for extraction were time (X1: 5.0-55.0), temperature (X2: 26.0-94.0), and ethanol concentration (X3: 0.0%-99.5%). Quadratic regression models were derived based on the results of 17 experimental sets, and an analysis of the variance was performed to verify its accuracy and precision of the regression equations. Results: When evaluating the effects of independent variables on responses using statistically-based optimization, the independent variable with the most significant effect on the TPC, TFC, and RSA was the ethanol concentration (p = 0.0008). The optimal extraction conditions to satisfy all three responses were 35.8 minutes, 82.7℃, and 96.0% ethanol. Under these conditions, the inhibitory activities of α-glucosidase and pancreatic lipase by the extract were 86.4% and 78.5%, respectively. Conclusion: In this study, UAE showed superior extraction efficiency compared to conventional hot-water extraction in the extraction of polyphenols and bioactive materials. In addition, α-glucosidase and pancreatic lipase inhibitory effects were identified, suggesting that peanut shells can be used as effective antioxidants and anti-obesity agents in functional foods and medicines.

In the modern management literature, knowledge has been recognized as a new strategic resource enabling a firm to create its competitiveness. Shipping companies under fierce competitive structure need to pay attentions to the utility of knowledge management. A shipping firm may develop its unique service capability by classifying, sharing, and transferring the data, information and knowledge obtained from both inside and outside its global service network. The current study attempts to analyze influential relationships between liner shipping firms' knowledge management and service capabilities. In order to achieve this goal, this study designed a knowledge chain model measuring shipping companies' knowledge management levels and tested its validity and reliability based on a total of 80 replied questionnaires from national and foreign liners. The empirical result presents that supportive and primary activities composing a knowledge chain could exert significant positive influences on the enforcement of shipping service capabilities. This research shows that the utility of knowledge management is adoptable in the maritime industry, and recommends that shipping firms should recognize strategic importance of knowledge and actively pursue knowledge management at an entire firm level.
