  • Shipping is a global industry, with 80% of the world's international trade of goods transported by sea. Many countries with large international trade volumes place great importance in developing their shipping industry. Recently changes in the world economy, international trade, world oil prices and other uncertainties have led to increased competition in the world shipping market. This is specially true, along the Pacific coast, where five of the world's major maritime countries, Japan, China, South Korea, Singapore and the United States are located. This paper aims to compare the international competitiveness of Japan, China, South Korea, Singapore and the United States with Port's Diamond Model and AHP analysis. The results of this research give some suggestions for international competitiveness of Chinese shipping industry, is very competitive in quantitative terms but is relatively weak in qualitative terms.

  • This study focused on the supply-demand and training system of the crew for domestic coastal shipping. First of all, it forecasted the prospect and effect in the future of the crew supply-demand through the analysis to the current situation of crew employment and the internal and external environment changes. Next, it suggested the specific role and alternatives of government, industry and educational institutions after the comparison and examination of the sailor policies among Korea and major shipping countries. In regard to the demand of crew manpower in coastal shipping, it figured out the bottoms and the current circumstances of sailors, and it could anticipate the future demand by the gradational approach. According to the findings, firstly the result of this simulation by the changes of the ship numbers demonstrated that the demand over the next 10 years will be 7,890~8,025 in the case of the growth 0.4%, and 7,894~8,063 in 0.5%. Secondly, assuming the growth 0.1~1%, the result illustrated that the demand will come to 7,879~8,258. This means the fact that the additional manpower has to be input to 20~430 annually from now on. To conclude, this study showed the more rational numbers about the supply-demand than the past researches and displayed the systematic approach to supply and train the crew in domestic coastal shipping.

  • The International Maritime Organization(IMO) which is responsible for measures to improve the safety and security of international shipping and to prevent marine pollution from ships is a specialized agency of the United Nations. It is involved in legal matters, including liability and compensation issues and the facilitation of international maritime traffic as well. But the ROK has not been actively coping with the environment of the shipping industry because of the absence of the organization or researching bodies that specialized in the field related to IMO. Therefore this paper investigates the maritime administration system of the major countries such as the USA, japan and the UK. And particularly by conducting IMO research and responding system, this study gathers relevant materials from those countries for the comparison and analysis with the purpose of providing the ROK with the assistance in forming the responding measures in the shipping and shipbuilding industries.

  • This paper uses input-output techniques to analyze the impacts of the coastal and inland water transportation (CIWT) upon the Korean economy between 1990 and 2000. The impacts were identified by means of backward and forward linkages effects, production inducing and import-inducing effects, and commodity prices repercussion effects of the coastal and inland water transportation. The data of this study come from The Bank of Korea databases for Input-Output Structure of the Korean economy. The major findings in this study can, among others, be summarized: that the power of dispersion(=backward linkage effect) and the degree of sensitivity (=forward linkage effect) of CIWT are higher than those of the deep sea transportation sector and that it has higher production-inducing effect than the average of total industries, while it has lower import-inducing effect than the average of total industries.

  • 수역의 유기오염 개선을 위하여 생활하수, 산업폐수 등의 저하시키는데 주안점을 두어왔으나 공공수역에서의 제거되지 않은 질소와 인의 유입으로 부영양화가 진행되어 하천에는 남조류가 대량발생하고 해역에는 적조가 광역에서 발생하여 큰 사회문제가 되고 있고, 질소와 인의 유입으로 인한 자생 COD가 전체COD의 약 절반을 차지하고 있는 실정이다. 따라서 앞으로의 수질을 개선하기 위해서는 조류증식의 제한인자인 질소와 인의 규제가 필요할 뿐만아니라 하수처리장에 고차처리를 적용하거나, 해양의 회석자용을 이용한 Ocean을 적용하여 연안해역 수질을 관리해야 할 것이다. 따라서 본 연구는 수영만을 대상으로 Ocean Outfall과 폐수처리시절을 적절하게 조합하기 위해서 3차원 생태계모델을 적용하여 유기물질 뿐만 아니라 영양염류인 질소와 인의 농도를 예측하여 환경기준을 만족시키고 비용을 최소화 할 수 있는 폐수처리공법과 해중방류관의 위치를 선정하고자 하였다. 본 연구결과 수영만의 1994년 COD는 II등급, DIN과 DIP는 III등급이었다. 현재의 활성슬러지공법으로 질소와 인을 제거하지 않고 방류할 경우 2001년에 는 하수처리량의 증가로 인해 COD의 경우 1994년 보다 조금 감소하지만 DIN 과 DIP는 1994년과 같은 III등급을 유지하였다. 고도처리공법을 도입할 경우 COD의 농도는 광안리와 해운대해수욕장에서 I등급을 보이고, DIP의 농도도 수영만 전체에서 강등급을 보이지만, DM의 농도는 광안리해수욕장에서 II등급, 해운대해수욕장에서 IH등급을 보였다 하수처리장 유출수를 Ocean Outfall을 이용하여 하수처리장으로부터 4km에 서 방류할 경우의 COD농도는 I등급을 보이고, DE 농도도 광안리와 해운대해 수욕장에서는 I등급을 보이고, DU의 농도는 ll등급을 보여 수질이 개선된 것 을 볼 수 있다. 이상에서와 같이 광안리와 해운대해수욕장의 해역환경기준 ll등급을 만족 하는 하수처리방법은 Ocean Outfall이었다. 수영하수처리장에 인을 처리하기 위한 화학적 침전법의 경우 956억원이 소요되고, 질소를 제거하기 위한 질소제거공정을 추가 건설 할 경우는 2181억원이 전요된다. 그리고 두공정을 같이 건설할 경우에는 3137억원의 비용이 소요된다 수영하수처리장에서 4km 거리와 관경을 2m의 Ocean Outfall 건설비용은 325 억원 정도가 소요되는 것으로 산출되었다. 고차처리시 증가되는 비용으로 건설할 수 있는 Ocean Outfall의 길이는 인 제거공정을 첨가하는 경우에는 18km을 건설할 수 있고, 질소제거공정을 첨가 하는 경우에는 46km를 건설할 수 있는 것으로 산출되었다.
