Many studies have identified the determinants of shippers' selection of ports, and of these, a number have repetitively cited major elements. However, different researchers came up with somewhat different research results depending on the position and preference of research targets. Accordingly, to deduce the determinants of shippers' selection of Gwangyang Port, appropriate research and analysis is required in addition to literature study. This study first deduced from previous studies the determinants that have influence on shippers when selecting a port and positively analyzed the effects of those determinants on the shippers using Gwangyang Port. In this regard, whether shippers using Gwangyang Port have continuously used the port was set as a dependent variable, and port service, port facilities, location of ports, port costs, and other determinants for port selection deduced in the previous studies were set as independent variables. This study's analysis finds shippers using Gwangyang Port are all influenced by the elements of port service, port facilities, location of ports, and port costs in their selection of Gwangyang Port. Their degree of importance is in the order of port costs, location of ports, port service and port facilities. This indicates that shippers consider port costs and location of ports more important than port facilities in their selection of a port.

Many studies on port tariff have been done over twenty years using publicly assessed data on tariff. Public data for tariff rates do not reflect, however, the port tariff in a real market, since the cargo handling charge, which is the important fraction of port tariff, is confidentially decided by the negotiations between a shipping company and a container terminal operator. In this paper, we collected the real price data of the port tariff on the world major sixteen container ports from a global shipping company and transformed it into the tariff per TEU(US$/TEU). The comparative analysis of port tariff was performed using the port tariff per TEU, and a panel regression analysis was done to identify the relations between the port tariff and demand variables: throughput, GDP and trade amount.

This study intends to verify the effectiveness of incentive schemes at Busan Port' aimed at promoting transshipment cargo. The current incentive schemes of Busan port intended to increase the T/S cargo volume have been disputed constantly. It is imperative, therefore, to restructure the system in accordance with the planned strategy. In this study, in order to ensure objectivity of the incentive schemes, all the parties (carriers, terminal operators and Port Authority) with a direct interest are answered and analyzed using the AHP methodology. Effectiveness is the top priority in the analysis of beneficiary validity of incentive schemes, when incentives are provided to Global overseas carriers compared with Global national carriers, IntraAsia carriers and Terminal operators. In the analysis of incentive schemes, direct cash support corresponding to the quantity of the T/S cargo had the highest effectiveness compared with exemption of port dues, cost compensation, port infrastructure support and subsidy for the service opening. The study results, therefore, reference the Port Authority when restructuring the schemes. This study has been conducted only focusing on the Busan port; however, the findings may have significant implications for overseas Port Authorities intending to implement incentive systems to promote cargo volumes similar to those at Busan port.

Recently, 8,000TEU class containerships has started operating the shipping service and the mega-containership of over 10,000TEU is on planning. A unit cost in relation to shipping service is decreased by the bigger ship based on the economy of scale. Most of the previous studies have been performed and focused on the total operation cost from mega port to mega port. However, the purpose of this paper is to estimate economic efficiency of selected hub ports from point of view of total cost such as service cost(or operation cost), port charge and feeder cost, etc. First, the service-network of mega containerships is based on data of a domestic shipping company operated main line and economic analysis of individual scenarios on the cost and traffic when 10,000TEU mega containerships offer the services. The three scenarios presented in this paper set up the hub ports which are the port of Busan, Shanghai and Yokohama The results show that port of Busan is economically the most efficient one among others.

"하천법" 제50조는 하천수의 사용용도를 생활 공업 농업 환경개선 발전, 그리고 주운 등 하천수 사용용도를 다양화하고 있으나, 하천수 사용료의 징수대상은 발전용수, 농업용수, 생공용수, 그 밖의 용수 등 4개 용수를 대상으로 하고 있다. 발전용수는 $100m^3/d$ 에 대하여 연액 231원, 농업용수는 $1,000m^3/d$에 대하여 연액 231원(발전용수의 1/10), 생활 및 공업, 기타용수는 댐용수대를 적용(2018년 현재 52.7원/$m^3$)하고 있다. 댐용수 요금의 산정은 '댐용수를 공급하는데 소요되는 총괄 원가를 보상하는 수준'에서 결정되며, 총괄원가는 '댐용수를 공급하는데 소요되는 적정원가에 댐용수사업에 공여하고 있는 자산에 대한 적정투자보수를 가산한 금액'으로 한다. 우리나라의 생활용수 및 공업용수는 이처럼 "한국수자원공사법" 제16조제2항에 따라 국토부장관이 승인한 댐용수 단가를 적용한다. 댐용수의 산정기준은 댐용수를 공급하는데 소요되는 총괄원가이지만, 하천수로서의 생활용수 및 공업용수가 이러한 댐용수 단가를 적용하는 이유에 대해서는 이론의 여지가 있을 수 있다. 댐용수는 1987년 최초로 전국 동일요금이 적용되었고 그 이후로도 주기적으로 요금이 인상되었으며, 발전 및 농업용수는 2008년 "하천법 시행령" 개정에 의해 사용료가 결정되었다. 농업용수와 발전용수는 각 지자체의 조례에 의해 요금을 부과하였는데 최초의 단가는 농업용수가 톤당 0.00032원, 발전용수는 톤당 0.0032원, 그리고 공업용수는 톤당 0.0076원이 부과되었다. 이후 1981년 조례의 개정에 따라 공업용수는 관경에 따라 차등적인 요금체계가 확립되었는데 대략 톤당 0.01원으로 기존에 단가에 비해 비약적으로 증가하였다. 농업용수 및 발전용수의 단가가 1984년 대비 2배 상승한 것에 비해 공업용수단가는 약 7,000배가 상승하였다. 생활용수의 경우, 기존 조례에서 따로 정하지 않았고 2008년 하천법 개정과 더불어 각 조례에 규정되었다. 즉 2008년 이전까지는 생활용수에 대해 따로 요금기준이 없었던 것으로 파악된다. 이에 비하여 농업용수 및 발전용수는 1984년 2배로 상승한 뒤 현재까지 동일한 요금을 부과하고 있다. 2008년에 개정된 "하천법 시행령" 제57조(하천수 사용료의 징수)의 농업용수 및 발전용수의 단가는 기존 조례의 단가를 그대로 "하천법"이 계승한 것으로 해당 용수의 단가가 특정한 과학적 기준으로 정해진 것으로 보기는 어렵다. 따라서 현재와 같이 용수단가별로 나타나는 커다란 차이는 각 용수의 용도 및 성격, 사회적 영향 등 용수 속성에 관한 사항과 더불어 회귀율과 취배수거리 등 다양한 요인을 적용한 산정기준을 적용하는 것이 바람직할 것이다.

Hot pepper (Capsicum annuum L.) is a valuable plant that is widely used worldwide for food and medicinal purposes. This study compared ethanol extracts of five native Korean varieties (Yuwol-cho, Subi-cho, Sumihyang, Gounbit, and Chilseong-cho) and five improved varieties (Dabok, Cheongyang, Chungseong, Olbokhap, and Shin-honggildong) of peppers cultured in Korea. The extracts were analyzed for color difference, polyphenol content, and their antioxidant, antidiabetic, and antithrombotic activities. The extracts of the improved varieties exhibited higher levels of redness and lower levels of yellowness compared to the native varieties. Polyphenol and flavonoid content analysis revealed significantly higher levels in the Yuwol-cho and Sumihyang varieties, which also exhibited scavenging activities in 1,1-diphenyl-2-picryl hydrazyl anion-, 2,2-azobis(3-ethylbenzothiazoline-6-sulfonate) cation-radical scavenging, and reducing power assay. The Chilseong-cho, Yuwol-cho, and Dabok varieties showed significantly higher nitrite scavenging activity. Antidiabetic activity based on α-glucosidase inhibition was observed in the Subi-cho, Sumihyang, and Gounbit extracts. Evaluation of antithrombotic activity showed that the Yuwol-cho extract prolonged thrombin time by 1.61 times compared to the solvent control at a concentration of 5 mg/ml, while the Dabok extract prolonged prothrombin time and activated partial thromboplastin time by 1.33 times and 2.21 times, respectively. All pepper extracts showed no erythrocyte hemolysis activity up to a concentration of 5 mg/ml. Our results suggest that native Korean peppers have the potential to serve as valuable sources of antioxidant, antidiabetic, and antithrombotic agents. This research also indicates the possibility of replacing improved pepper varieties, which incur significant seed usage fees, with native Korean pepper varieties.

Gyeongin Port has low awareness, insufficient hinterland infrastructures, and lower competitiveness. So, in this study, we conducted Fuzzy-IPA analysis reflecting the recognition of the consignor companies that are using Gyeongin port to suggest present practical improvement measures for the activation of the operation of Gyeongin port hereafter. As a result of the analysis, three factors, that is, cargo loading/unloading/storage costs, port facility fees, and incentive and support were derived as priority investment areas. Three factors, that is, cargo safety, infrastructure equipment, and inland transportation costs were derived as the areas for maintenance strengthening and factors related to cargo handling and service factors were derived as areas for maintenance of the status quo and areas for gradual improvement, respectively. This study is significant in that it analyzed the recognition of the consignor companies that are using Gyeongin port using a quantifying method and suggested realizable measures for activation based on the results of the analysis. In future studies, the frequency of ships' calling at the port and measures to diversify the sea routes should be additionally reflected on the analysis.

Illuminating Japanese Fisharena Development Policy, we tried to find out some implications on the utilization of fishing port facilities as a way to accommodate uprising marine leisure demands of Korea. The major findings of this study are concentrated in the following three points. First, Japanese Fisharena Development Policy can be functionalized in Korea as a means of policy, but for the intervening difference of demand situation, precise forecasting on the marine leisure demands has to be preceded and Fisharena should be prepared as a supply buffer. Second, in the development stage of Fisharena, Software side is important as well as Hardware side. On the development and operation, utilizing civil organizations is necessary to bring down the wharfage of Fisharena to not suppress the marine leisure demands. Third, selection of the fishing port and decision of the development scale are additional important points. In particular, preferential consideration of utilizing inner-city fishing ports as small-scale Fisherinas to address the marine leisure demands would be desirable in Korea.

Korea's trade balance in service showed surplus in 2012 on the basis of BPM5. This is recorded by 14 years since 1999. This owes to decrease of deficit in tourism balance, increase of surplus in construction and transportation, and shift from deficit to surplus, even in small portion, in personal cultural recreational services balance. While externally the global economic growth becomes inactive and the Korean Won has appreciated, internally Korean service industry is very weak and is not equipped with international competitiveness. This study intends to look into service surplus items and services deficit items and to present measures that will be able to strengthen competitiveness in service industry. As a short case study, German and Japan was benchmarked, as they are the countries which are developed on the basis of manufacturing like Korea. And in this study, by analyzing surplus items and deficit items in trade balance sheet, it is attempted to suggest policies which would be available for strengthening service industry. As the service industry is a highly value-added one, it is necessary to designate promising categories and intensively foster as strategic industry. Service industry has their own characteristics distinguished with manufacturing goods. It has very different logistics and payment system with manufacturing industry. It means there must be independent support systems which reflect the nature of industrial classification in service industry. It is necessary to provide export support system, to organize export market development group, to support marketing, to set common logistics center, to support diplomatic means, to provide legal service and so on.
