This paper studies the economic effects of port-liquid freight by focusing on Ulsan port and its regional economic effects. The direct industrial effects of port-liquid freight are analysed to be an increase in about 1billion dollars' worth of production of the regional port-logistic industry, an increase in about 0.22billion dollars' worth of value-added of the industry, and the creation of about 2,600 employment in the industry. Including the indirect effects, the total effects on Ulsan regional economy are estimated to be an increase in about 1.9billion dollars worth of production, an increase in about 0.51billion dollars' worth of value-added and an increase in about 6,442 employment.

울산항은 우리나라 최대의 산업지원항만이며, 물동량 처리면에서 국내 3위를 점하는 위상을 확보하고 있다. 또한 액체화물 처리량은 국내 1위이며, 울산항 전체화물 처리량 중 액체화물 처리 비중이 2010년 기준 79.4%로 압도적이다. 그러나 항만의 난개발로 인해 일반화물과 액체화물이 같은 부두에서 처리되고 있는 경우도 있으며, 항만시설 부족으로 인하여 체선과 체화현상이 극심하다. 본 연구는 울산항 항만운영 활성화 방안으로 포항항과 연계하여 항만 배후에 위치하는 국가산업단지의 특성에 맞추어 일반화물을 포항항으로 이전하였을 때의 효과를 제시하고자 한다.

세계의 주요 자원중 하나인 원유는 산업의 가장 기초적인 부분을 담당하고 있다. 대한민국은 대표적인 원유수입국이며 원유 자원 등을 수입을 하지 못한다면 내수 및 가공후 수출에 큰 위험으로 다가온다. 그렇기에 원유 수입 등의 액체화물 수입이 필수적이다. 차별성을 두기위해 액체화물 항만간의 경쟁을 확인하고자 울산, 대산, 여수광양항을 선정하였다. 항만들은 석유화학단지를 보유하고 있는 항만이며 원유는 수입후 정제를 통해 석유정제품, 화학생산공업품의 물품을 생산한다. 시계열 데이터를 이용한 VAR 모형을 이용하였다. 이를 수행하기 위해 단위근 검정을 실시하였으며 토다 야마모토 인과 검정을 통한 항만간의 관계를 확인하였다.

This purpose of this paper is to study the economic effects of port-liquid freight by focusing on Korea port and induce its policy implication. For this, 29 sectors' input-output tables with port-logistic sector as an individual sector is constructed. The direct industrial effects of port-liquid freight are analysed to be an increase in about 3.6billion dollars' worth of production of the port-logistic industry, an increase in about 1.98billion dollars' worth of value-added of the industry, and the creation of about 11,589 employment in the industry. Including the indirect effects, the total effects on Korea economy are estimated to be an increase in about 4.9 billion dollar's worth of production, an increase in about 2.4 billion dollars' worth of value-added and an increase in about 17,746 employment. The total effects of port-liquid freight on Korea economy is about 2.5-3.0% of that of port-logistic total freight. the results suggest tkat thought economic effects of port-liquid freightare not large, we have to focus on policy support for port of port-liquid freight.

This study aims to suggest a containerization plan for non-standardized cargo; it also reveals the significance of containerization in facilitating freight inducement and cargo creation for increasing the competitiveness of the Gwangyang port container terminal and checking excessive competition among terminal operators. Therefore, this study suggested a containerization plan and its significance by dividing 14 items, ones with low containerization ratios or undergoing containerization, bulk, and liquid cargoes. In the case of general cargo, it will be necessary to raise the utilization rate by remodeling a general container or improving cargo loading techniques. In the case of bulk cargo, it will be necessary to exploit the benefits of containerization in preventing product deterioration due to rain, facilitating the sale of small orders, ensuring clean cargo handling, and reducing logistics cost, among others. In the case of liquid cargo, it will be necessary to order and sell liquid cargo in small quantities by using superior quality, safe, and durable Flexitank or Flexibag products, which offer transportation convenience and reduce time and costs.

Direct Borohydride Fuel Cell은 알칼리 붕소 수소화물의 수용액을 이용하는 연료전지로 연료의 직접 산화반응을 통해 기존의 DMFC(직접 메탄을 연료전지)보다 높은 전류밀도와 OUV(Open Circuit Voltage)를 나타낸다. 또한 액체 연료를 사용하므로 장치 구성이 간단하며, 사용하는 연료가 반응성이 높은 알칼리 붕소 수소화물로 이루어져 있기 때문에 탄화수소 계열의 액체 연료와 달리 전기화학 반응이 비귀금속 전극에서도 쉽게 이루어질 수 있다는 장점을 가지고 있다 하지만 강알칼리 조건에서 전기화학 반응이 진행되므로 이에 적합한 재료로 장치를 구성해야 하며, 액체 상태의 연료가 전해질을 투과하는 현상인 크로스오버 문제를 해결해야 하고, 생성물인 $BO_2$-가 침적되어 전지효율을 떨어뜨리는 것을 방지해야 하는 문제점이 있다. 또한 알칼리 붕소 수소화물이 물과 반응하여 수소를 발생시키는 hydrolysis 반응을 억제하여야 하고 직접 산화반응만이 진행될 수 있도록 전지를 구성해야 연료효율을 높일 수 있다. 따라서 본 연구에서는 수소 생성반응일 hydrolysis 반응은 억제하고 연료의 직접 산화반응만을 진행시키기 위한 전극촉매에 대하여 연구하였다. 일반적인 저온형 연료전지의 전극촉매로 사용하는 Pt등의 귀금속 촉매와, 귀금속 촉매를 대체할 수 있는 Ni등의 비귀금속 촉매를 그 연구 대상으로 하였으며, 평가 방법으로는 unit cell station을 이용한 단위전지 성능측정 실험과 Potentiostat/Galvanostat을 이용한 half cell 실험을 병행하여 수행하였다.

One of the world's major resources is crude oil, the most fundamental part of the industry. There is no place that does not use crude oil. Petroleum refining products and chemical production industrial products are produced through nearby petrochemical complexes and ports after importing crude oil. There would be a possible relationship among the petrochemical complexes and nearby regional ports working with liquid cargoes. To confirm these relations, Ulsan Port, Daesan Port, and Yeosu Gwangyang Port were selected for this study. A Vector Auto Regressive model using time series data was applied. A Unit Root Test was performed. The relationship was confirmed through the Granger and Toda Yamamoto Causality Test.

Since Korea has excellent port infrastructure and competitive petrochemical complexes, there is plenty of potential for creating an oil hub in Northeast Asia. In particular, Ship-to-Ship (STS), which creates high added values, contributes greatly to the national economy. In this study, the liquid cargo volumes of chemical industrial products, refined petroleum products, and crude oil were analyzed at the national and regional (Busan, Ulsan, and Yeosu/Gwangyang) levels. Additionally, a Granger causality analysis was performed between imports, exports, and transshipments, in pairs. ADF, PP, and KPSS were analyzed for the unit root test. In addition, the VAR model and expanded VAR model suggested by Toda and Yamamoto were used for further analyses. Findings revealed a difference in Granger causality depending on the region or cargo type. These findings suggest that policies and incentive schemes for ports need to be differentiated according to the region and cargo types. In addition, the different patterns in the relationship between transshipments and import-export petrochemical cargoes should be considered.
