The criteria of tugboat requirement in domestic trading ports have been determined by the administrator of regional maritime affairs and port office on the basis of the regulations for the tugboat operations and management. But, there is a little confusion that the criteria of tugboat requirement and method for calculation of them are different from port to port and total power calculated on the basis of power per tugboat requirements by the number of tugs is not in accordance with total required power for the use of tug in several ports. The comparison of tugboat requirements among domestic major ports showed that it should be necessary for the criteria to be made in unified form. Because the current criteria are only on the basis q the ordinary condition with wind velocity under 10m/s, the criteria on the condition of the wind velocity over 10m/s are suggested to be necessary for the precautions against a disaster such as unexpected strong winds or typhoon.

The purpose of this study is to estimate and forecast the marine trading volumes based on the structural model. We employ GPH cointegration test since the structural model must be stationary to get the accurate predicted values. The empirical results show that our model is stationary. This paper also applies variance decompositions and impulse-response functions to the structural model composed of exchange rate, domestic industrial activity, and world business. The results indicate that while both loading and unloading volumes respond positively to the shocks in income and then decay very slowly, their responses are different to the shocks in exchange tate.

This research is to reveal an aspect of costume culture and a phase of the cloths in the relationship of the Chosun dynasty, by considering the exported goods from the Chosun dynasty of the trading goods derived by the trade diplomacy between the two countries in the Chosun dynasty-Japan relationship in the 15th and 16th. The research findings, by analyzing various literatures and related documents, follow. The research results are as follow. The exchange was the form of presenting a return present in return for a tribute to the Chosun dynasty from the Japanese envoy, which has a polycentric characteristic. Pusanpo, Naipo, and Yumpo were designated as the open ports, which played a pivotal role in the Korea-Japan exchange. The imported goods were somok, peppers, drug-stuffs, gold, bronze, sulfur, etc. The exported goods were books and cloths, such as hemp cloths, cotton cloths, silk, etc. The majority of exported goods was cloths, particularly cotton cloths. Meanwhile, in the 15th and the 16th century, with expanding of active trade towards Japan, the amount of export increased rapidly. As a result of the increase of exporting cotton cloths, the raw cottons production was increased and cotton cloth manufacturing was developed. However, it also expanded a dual structure of cotton cloths between the cotton cloths for exports and the cotton cloths for domestic markets. This dual structure of cotton cloth was lead to the deterioration of cotton cloths and had an effect on the price increases of domestic markets.

Busan Port, as Korea's representative trading port, handles a variety of port cargo from bulk cargo to container cargo. Busan Port is currently functioning as a container specialized port for North Port and Busan New Port, and Gamcheon Port is also handling container cargo mainly in bulk cargo. This study intends to examine the overlapping cargoes and specialized cargoes between these ports and Busan Port as the amount of import and export cargoes in ports designated as trade ports in Korea is increasing. In order to understand the characteristics of the major cargoes handled in the port, the quantitative change is confirmed through the total cargo volume of major domestic ports and the trend of changes in import/export cargo between Busan Port and major ports is analyzed. There are many specialized investigation methods, but as the most basic method, we will examine quantitative changes and causes by simply examining the data for 10 years as the amount of change by cargo. In addition, the causes of these fluctuations should be reclassified into domestic and foreign causes by identifying changes in customers in different ports and shipping volumes, changes in consumption areas, and transshipment volumes. Through the analysis of the major cargo volume of each port, the characteristics and fluctuation trends of major cargo handled in Busan Port and other ports are identified, and the competitive cargoes of each port are verified. Through this, the characteristics and competitiveness of the port are inferred, and implications for the cargo volume of Busan Port and future countermeasures are suggested.
