The pilotage tariff system in port operations has received little attention in the academic literature. While studies addressing legal issues-such those concerning liability, marine accidents, and compensation for accidents-and institutional aspects have been prevalent, scant research has been conducted in the form of comparative analysis of pilotage tariff systems and current levels of pilotage charges in major ports. The purpose of this research is to investigate the rate structure of pilotage tariffs of major ports. Specifically, this study explores the current level of pilotage price and regulations by comparing the pilotage systems of six major hub ports in the world: Busan, Kobe, Hong Kong, Los Angeles, Singapore and Rotterdam. Results show that Busan Port's pilotage tariff system ranks low (5th) among these six ports. Another finding is that the simplification of Korea's pilotage tariff system will yield productivity and efficiency improvements in this area.

To accurately forecast the supply and demand of harbor pilots, it is necessary to derive the determinants of demand because they are directly linked to securing the safety of ships and ports. The securing of an appropriate numbers of harbor pilots can create conflicts of interest among the pilots, the Ministry of Oceans and Fisheries, and users of pilotage services as it is also a matter directly related to harbor pilots' income. Therefore, a measure is needed to ensure a suitable number of pilots can be maintained, through which high quality pilotage services can be provided. This can be achieved by deriving reasonable determinants for estimating and forecasting demand, which satisfy all stakeholders involved in pilotage service. To reveal the challenges posed by the current determinants regarding the demand for harbor pilots used by the Central Pilotage Operation Council, and arrive at solutions, this study derived three determining factors, namely the total annual average piloting time, the average working hours of pilots, and the current number of pilots. These were used to determine the demand for harbor pilots. This study used a survey and analysis of current determining factors, a questionnaire survey administered to the interested parties, a case study of selected countries, and so on, as the research methodology.

최근 국내외 여러 사건들로 인하여 VTS의 중요성이 대두되고 있는 바, 보다 더 안전한 해상 환경을 조성하기 위해서는 VTS 여러 부분의 개선과 발전이 필요하다. 여기서는 VTS의 발전을 위해서 필수적으로 요구되는 비용에 관한 부분을 해결하고자, VTS 사용료 제도에 관한 다른 비슷한 성격의 항만 요금과 외국의 VTS Fee 사례에 대하여 검토하고 비교해보고자 하였다. VTS 사용료로 인하여 여러 가지 기술적 개발을 이루어 원활하고 효율적인 VTS 관제가 이루어질 수 있도록 모색하고자 한다.

Mokpo port marked the $131^{st}$ anniversary of its opening in 2018. while the Mokpo has taken the new port development initiatives, it is limited by inefficient port functioning due to the lack of maritime port policy and government investment. Hence, port logistics has not been activated. Additionally, studies on Mokpo port have not been conducted, and knowledge available on the port is declarative in nature. On the other hand, research on port competitiveness focuses on how to analyze the factors that determine port competitiveness. Therefore, this study was intended to expand the existing research on Mokpo port and conduct an analysis of non-competitiveness factors and suggested improvements by considering the operational aspect of Mokpo port. In this regard the importance of non-competitiveness factors was assessed through an analytic hierarchy process(AHP) analysis and the influence of the non-competitiveness factors was analyzed through an fuzzy structural modeling(FSM) analysis. The result of the AHP analysis show ed the important non-competitiveness factors included the deactivation of industrial complexes around Mokpo port, the number of liner route, the cost of the pilot and tug. Accor ding to the FSM analysis, the top level included the non-competitive factors at Mokpo port; the intermediate level included the number of liner routes, cost of pilot and tug, enrance and clearance fee, costs of inland transportation, fee for port facilities, and loading and unloading costs; and the bottom level comprised the most non-competitive factors including the deactivation of industrial complexes around Mokpo port, hinterland connectivity, access to international port, incentives, and cost of transportation and storage. Based on the results of analysis, improvements were suggested for non-competitive factors of Mokpo.

We studied the annual variation of water temperatures in the upper 200m off southeast coast of Korea by means of harmonic analysis of the temperatures at 10 standard depths of 51 stations. The distributions of the mean temperature in coastal zone are almost parallel to the coast, whereas those in offshore are almost zonal. With an increase of depth, the annual amplitude decreases nearly exponentially and the annual phase increases nearly linearly. The average e-folding depth for the annual amplitudes is 65m, vertical change of the annual phase is 180 per 200m, and the vertical eddy conductivity is $4\textrm{cm}^2/sec$. Annual variations of temperatures in the coastal zone of a few tens miles from the coast are considerably different from those in offshore area. The e-folding depths in coastal zone are shallower than those in offshore region, and the changes of phase with depths in coastal zone are smaller than those in offshore region.
