This paper discusses the strategies for the future qf the Hong Kong Port and Buasn Port. We assess whether they prepare the ports for the position of being the logistics hub, and as such could assist the ports to maintain their position in the world's container port. We reviewed both the current situation qf the Hong Kong Port and the strategy of the port for the future (Master Plan 2020) to keep the status of logistics hub. With the case study on the Port of Hong Kong, this study attempts to examine what the strategic planning is needed for the Busan Port. We debate the Port of Busan could be seen as a logistics chain for the future. In our discussion, the strategic planning on "Port Vision 2020" for Port of Busan does not address the issues regarding this part, nor does it make any recommendations in terms of the requirement of the logistics private sector.

세계의 선진항만인 싱가포르항과 홍콩항의 여건 및 특성은 물론 이에 근거한 이들 두 항만의 발전전략을 비교분석하여 부산 신항의 합리적인 발전전략을 모색한 결과는 다음과 같다. 싱가포르항과 홍콩항의 공통적인 발전전략에서 부산 신항의 발전전략으로 합당한 것으로 부산 신항이 이미 실시하고 있는 것은 주요 전략산업으로 항망물류산업을 성장동력신업으로 육성, 하역 보관 배송 등 전통적 물류활동보다 항만배후단지에서 이루어지는 부가가치 물류활동의 강화, 외국자본과 상품에 대한 우호적인 인식 등이다. 여기에 새로운 전략으로서는 환적화물 무료 장치기간의 연장, 하역료의 최대한 인하 및 우대요율 적용, 행정절차 및 관행의 수요자 중심으로 개선, 연구 개발 및 인력 양성의 추진 및 국제적 언어 구사능력의 제고 등을 들 수 있다. 그리고 싱가포르항의 발전전략 중에서 부산 신항의 발전전략으로 유용한 것은 포트넷시스템과 Cargo D2D체제의 도입이며, 홍콩항의 발전전략 중에서는 수출입화물의 운송원가 절감전략이다. 그리고 이들 두 항만과 차별화된 부산 신항의 발전전략으로는 유 라시아 대륙을 잇는 철도운송의 추진, 3 port system의 구축전략, 신항의 배후단지 조기개발에 의한 자체 물동량의 확보, 항만 생산성의 획기적인 제고 및 항만마케팅 활동의 차별화 등이다.

This paper aims to describe port competition in East Asia and the Korean government's port strategy. In doing so, the paper provides an overview of global changes in international trade, the shipping industry and the port business. It also delineates the status of port competition in the region. Particular examples are taken from the competition among the ports of Hong Kong, Singapore, and Malaysia, as well as those of Pusan and Kwangyang, Kaohsiung, Kobe, and Shanghai and Yantian. The port competition in East Asia is reviewed and classified in two groups: north-tier competition among traditional major players, such as Kobe and Pusan, and dark horses such as Shanghai, Kwangyang and perhaps Yokohama; and south-tier competition among the three traditionally big players Kaohsiung, Hong Kong and Singapore, and the relative newcomers of Yantian in China, and Tanjung Pelepas In Malaysia. Due to the enlarging of ships and expansion of port activities, the boundary between the two tier frontiers breakdown, or they may even merge, into one grand frontier, in the foreseeable future. Although it appears that Asian ports are not being very aggressive in preparing for the future of mega-carrier in their plans, it is true that China, Korea and Taiwan are moving full steam ahead in comprehensively developing their container ports on a large scale. It therefore seems to be the perfect time for rival ports to explore a port alliance strategy to fight against the trend toward alliances between of many shipping lines.

Since the beginning of open-door policy, China has been making rapid annual growth with an average 10% economic development. And due to this rapid growth, cargo volumes via ports have been also rapidly increased, and accordingly, current China government has intensively invested in port development. Further, this development project is significantly big scale, compared with those project which Korea and Japan have. Thus, China is beginning to threaten Korean ports, especially Busan port which try to be a hub port in Northeast Asia. For this reason, it has been very important issue for Korea and Busan port to investigate or analyze Chinese ports based on empirical data. Especially, although various studies related to Shanghai and Hong Kong have been conducted, the competitiveness of overall Chinese major ports has been little studied. In this paper, we analyzed competitiveness level of eight Chinese ports with capabilities as container terminal, based on reliable sources. From data analysis, eight Chinese ports were classified into four groups according to competitiveness level. Rankings among four clusters based on competitiveness level are cluster(Hone Kong), cluster C(Shanghai), cluster A(Qingdao, Tianjin, and Yantian) and cluster D(Dalian, Shekou, and Xiamen).

The purpose of GPS structural vibration monitoring is to obtain information on the frequency and amplitude of vibrations based on GPS observations that are often affected by various errors. Filters are frequently used to improve GPS accuracy and to retrieve vibration signals from GPS observational series. This paper studies the performances of four commonly used filters, i.e., Vondrak, wavelet, adaptive FIR and Kalman filters, for such applications. Controlled experiments are carried out and the results show that the capability of GPS in tracking structural dynamics and complex signals can be improved with any of the filters. The performances of Vondrak and wavelet filters are almost the same and superior to the adaptive FIR and Kalman filters. Recommendations are given for the selection of filters and filter parameters for different situations based on an analysis of the advantages and disadvantages of each of the filters.

본 연구의 목적은 동아시아 지역을 중심으로 글로벌 항만 물류네트워크를 구축하여 우리나라의 새로운 항만정책을 제안하는 것에 있다. 이러한 항만 물류네트워크의 구축을 위해 세계 50위 항만 중 21개의 항만을 중심으로, 컨테이너 화물량과 기항지를 분석하여 EU, 북미를 연결시 최소 물류비용인 동아시아 지역의 4개의 대표항만을 추출하였다. 그 결과 동아시아에서는 싱가포르, 홍콩, 상하이, 부산항이 추출되었다. 따라서, 우리나라는 싱가포르, 홍콩, 상하이항에 해외 터미널을 운영하고 부산항과 연계하는 글로벌 항만 물류네트워크를 구축하여 안정적인 화물을 확보해야 한다.

This study aims to evaluate and compare the service quality level of major container ports in Asia. Seven factors are used to evaluate the port service qualities; informational assistance, location, processing speed, facilities, port operation, costs, and user convenience. Ten ports are selected as a sample; Singapore, Kobe, Osaka, Kaohsiung, Hong Kong, Shanghai, Tianjin, Busan, Kwangyang and Inchon. ANOVA and Duncan's multiple range test are used to analyze the survey data. The empirical results shows that, in general, Korean ports provides poorer service qualities than Singapore, Hong Kong, Kobe, and Osaka. Furthermore, the service quality levels of Korean ports are similar to or no better than Chinese ports.

In GPS Positioning, the error of satellite orbit will affect user's position accuracy directly, it is important to determine the satellite orbit precise. The real-time orbit is needed in kinematic GPS positioning, the precise GPS orbit from IGS would be delayed long time, so orbit prediction is key to real-time kinematic positioning. We analyze the GPS predicted ephemeris, on the base of comparison of EKF and UKF, a new orbit prediction method is put forward based on UKF in this paper, the result shows that UKF improves the orbit predicted precision and stability. It offers a new method for others satellites orbit determination as Galileo, and so on.

With development of Asia's economy, the ports in trunk route have increased its handling capacity According to previous studies, main determinants to become hub-port are referred to location, connection inland transport with hinterland, port service availability and efficiency, cost of port handling, socio-economic stability and port information system etc. This study aims to investigate the changes in factors determine port's competitiveness particularly in Asian neighbor ports such as Hong Kong port and Shenzen port, and Singapore port and the Port of Tanjung Pelapas in Malaysia by comparing and analyzing main indicators relating to those ports. In conclusion, main reasons which gained competitiveness by newly developed ports such as Shenzen port and the Port of Tanjung Pelapas were port price and massive hinterland space offered.
