  • The purpose of this paper is to introduce the new way of location choice for free trade zone in Busan area by using Obata and Ishii(2003) model of preference discrimination score. And also, this paper investigates the result of Choi, Bong-ho(200l) that deals with the choice of tariff free area in Busan area. Empirical main results are as follows: First, the North Port(Sinsundae)and the New Busan Port are efficient. Final winer of location choice for free trade zone is the North Port(Sinsundae). Second, the ranking result of this paper for 10 potential sites of free trade zone shows the almost similar to that of Choi, Bong-ho(200l). Policy planner for location choice of free trade zone should introduce the preference discrimination score method by Obata and Ishii(2003), because this method shows the very positive empirical results like questionaire method by expert groups and common people in Busan which should cause the much time and much money.

  • Traditional traffic forecast has employed regression analysis or time-series analysis based on past trends of explanatory variables. However, not existing but planned port facilities do not have historical data for traffic estimation. Consequently, arbitrary traffic allocation has been subject to researcher's intuition. In this paper, container throughput at New Incheon Outer-South Port will be estimated using stated preference(SP) and sample enumeration methodology on the basis of survey data about the choice behaviors of port users in a theoretical situation. In the SP survey, shippers, freight forwarders and carriers were required to answer a choice between two alternative ports: Busan and Incheon. Although total 27 scenarios of questionnaires were constructed with 3 levels of 3 explanatory variables, each interviewee was asked to answer for just 9 scenarios chosen at random. A binary choice logit model was applied to the survey data. The elasticity of travel time is estimated to be very high, implying that building New Incheon Outer-South Port could be effective in relieving the congestion of the Kyungin corridor. The analysis result shows that increasing service level at Incheon Port would bring in the substantial diversion of container cargo in the Capital region to Incheon Port from Busan Port.

  • In response to insurmountable pressure for a broad distribution of political power between the central government and local governments, the Korean Government pushes for the establishment of the local port authority as the optimum choice to achieve its goal. Starting with the Pusan and Incheon ports, the local port authority system is expected to setout the dramatic change in port management system throughout the Korean ports. However, this paper points out that the port reform choice should take into account the specific features of the society and country and some basic questions should be clearly answered beforehand. The fundamental questions are: whether institutional reform will markedly improve the ports managerial and operational efficiencies? and what will be the benefits and costs, compared to those of not changing? Without rigorous and comprehensive analysis on these issues in the institution transition, haphazard port reform will have the possibility to increase port users costs and disrupt the efficient port services. Experiences around the world clearly show that the indiscriminate copy of port reform found in other countries may be neither feasible nor practical presently in Korea. They also indicate that the port reform should be made on a gradual basis with full control of the pace.

  • This study was conducted to assess the level of satisfaction of undergraduates with the Library and Information Science (LIS) course and some of the factors that influence their choice of the programme. The population of the study was all the 400 level undergraduates in the Department of Library and Information Science, Faculty of Education, University of Port Harcourt. A structured questionnaire, made up of three parts, was utilized for data collection. The first part involved the level of satisfaction of the respondents with the LIS programme while the second and third parts involved the influence of parents and peers on the respondents' choice of LIS programme, respectively. Out of the 21 copies of the questionnaire distributed, 20 were retrieved indicating a 95.2% response rate with 75% (15) male and 25% (5) female. Data were analyzed using percentages and simple regression analysis. Results indicated that the respondents were highly satisfied with the choice of LIS programme and would recommend the programme to others. Parental influence on the respondents' choice of LIS programme was minimal accounting for 7.8% of the changes in the choice of the programme while peer influence on the respondents' choice of the programme was substantial accounting for 78.0% of the changes in the choice of the programme. The fact that the respondents were satisfied with their choice of career in LIS is a strong indication that they would be committed to providing excellent service in librarianship needed to cater for the mutated information requirements of the society.

  • According to the globalization of world economy on distribution and sales, logistics and transportation parts are playing an important role. Especially, they have to decide what is the key factor of route choice model and how to choose the right transport route in multimodal transport system. By considering the key factors in rote choice model for freight forwarders between Mongolia and Korea, this paper propose 4 main factors: Cost, Delivery time, Freight and Logistics service with 13 sub factors. The importance of factors is surveyed base on AHP through interview with freight forwarders. In results, the empirical insights about current status of Mongolian forwarders are provided with different factors between transportation modes. Expecially, the Time factor is a role factor to choose transport route for air transportation forwarders.

  • In the fish industry, the perishabiliy of raw material, saeasonality of catch and diatance between production and consumption combine to cause physical distribution to be a difficult decision problem. In fishery physical distribution, the choice of appropriate landing port is a major problem. This paper deals with transshipment model to determine landing port as intermediate transfer point and the market to which fish should be sent. Transshipment model is useful to determine intermediate transfer point and can be reformulated as LP model. So this study developes transshipment model for korea large trawler ana analized the model output. It can be expended to a realistic problem in order to provide information to port planner and decision maker on the trade-offs between the cost and efficiency of fishery transportation.

  • In order to attract more transshipment cargoes, Busan Port Authority (BPA) has, since 2003, adopted the volume incentive policy by which more than US$ 10 million annually have been paid back to shipping lines that were called at the port. However, having been a transshipment port for the Northeast region of China, the port of Busan has come under threat from bold Chinese port development projects, notably Shanghai, as northern Chinese regionnl ports place more emphasis on building facilities capable of handling growing trade volumes. Undoubtedly this would lead to a decline in transshipment container traffic moved via Busan. The purpose of this paper is to identify some core factors that have been affecting the increase of transshipment cargoes of Busan and further to recommend BPA an improved incentive scheme with which more T/S cargoes can be attracted into the port of Busan To clarity the reason why T/S cargoes have increased in the port of Busan, several steps are made as follows: The first step is to make a quantitative model for explaining the development of T/S cargoes during the last decade. The second step is to define the dependent and the independent variables for multiple regressions after testing variable significance. For this, data collection and the accuracy of validation have been done by the direct interview with the experienced staffs in shipping companies of both domestic and foreign country. After validating the model with collected data, the final step is to find variables which are explaining the model mostly. In conclusion, 2 variables were clearly identified as core factors that explain well the development of T/S cargoes in the port of Busan: 'Mohring effect' and total cost. It is strongly recommended, by an empirical study, that an incentive scheme be changed to a way which more feeder vessels rather than mother vessels can reduce their direct costs to call in the port of Busan.
