The shipping industry is a service industry that operates its business by transporting cargo on ships and receiving freight. Therefore, large-scale capital investment is required for ship operation, and if the value of the ship is uncertain, the risk of shipping management increases. This study aims to identify the factors affecting changes in ship value and to analyze the importance of each variable. To achieve the goal, the factors affecting changes in ship value were identified and structured using the techniques of text mining and topic modeling, and classified into three main factors and 12 sub-factors. This study used AHP analysis to examine the relative importance of each factor. Results indicated that the main factor influencing the change in the vessel value was the shipping factor, followed by the investment factor and the environment factor. Other auxiliary factors that substantially affect the ship value include the volatility of the shipping market and of shipping freight.

Although studies and investments on electro-magnetic fields in terrestrial areas are being conducted, they are not applied to a ship. Especially ship is consist of Top Side, Bridge, and Engine Room. Top Side is mounted Antenna and radar. Bridge is mounted navigation and navigation equipment that have a safe voyage. Finally, Engine Room is mounted switchboard and this is used to ship propulsion system. Therefore the purpose of this paper is for suggesting optimized standard to apply to marine environment through analyzing electromagnetic wave environment in ship. For this, we were measured EMF in Hanbada ship in Korea Maritime and Ocean University and we compared and analyzed to measured values in Korea standards and international standards. Consequently, Engine Room of ship for the identified that there are limits to apply. The proposed results of this research will be expected to utilize for establishing standard a plan for EMF in ship.

This study has investigated shipping finance systems in Korea and China, and extracted negative factors based on it to propose a way to develop the shipping financial system in Korea for shipbuilding industry and marine transportation. From after the global financial crisis in 2008 to right before the Lehman Brothers Holdings bankruptcy, shipping finance has been dominated by the major industrialized countries in Europe. However, the weight point is moving to the countries in Asia region such as Korea, Japan, and China based on relatively strong banking system and low interests rate. This study focused on the alternatives the current situation that the starter of shipping finance among three countries in Northeast Asia, South Korea is facing China's challenges. In the paper, shipping finance in Korea presented its defectives such as the limits of ship financing, lack of professional workforces, ever-present foreign exchange risks, and lack of understandings of the parties. As the countermeasures of them, it proposed establishing professional institute for ship financing, training professionals in financial industry, raising foreign credentials of won, and continuing associations between the parties. Even though we are the first Asian country introduced ship funds, the ship funds growth in China shall be under our eyes while we keep systemic networks between shipping, ship building, and ship financing.

The purpose of this paper is to show the empirical measurement way for predicting the seaport efficiency by using Super SBM(Slack-based Measure) with Wilcoxson signed-rank test under CRS(constant returns to scale) condition for 20 Korean ports during 11 years(1997-2007) for 3 inputs(port investment amount, birthing capacity, and cargo handling capacity) and 5 outputs(Export and Import Quantity, Number of Ship Calls, Port Revenue, Customer Satisfaction Point for Port Service and Container Cargo Throughput). The main empirical results of this paper are as follows. First, Super SBM model has well reflected the real data according to the Wilcoxon signed rank test, because p values have exceeded the significance level. Second,Super-SBM has shown about 87% of predicting ratio for the ports efficiency and the optimal size of investment in domestic seaport. The policy implication to the Korean seaports and planner is that Korean seaports should introduce the new methods like Super-SBM method with Wilcoxon signed rank test for predicting the efficiency of port performance and the optimal size of investment as indicated by Panayides et al.(2009, pp.203-204).

Nowadays, vessel's size is tending to bigger, Therefore port facilities are developed according to this trend, which has been shown in the competition of Hub-Port among the main ports such as Port of Busan and Port of Shanghai. However there are the limited number of large containerships more specifically so 70% of the total ships calling at Busan Port are small and medium sized ships which are less than 20,000 ton As a result, it is necessary to consider the handling facilities of these ships which had been disregarded The big size of facilities increases handling cost bemuse of high investment so it is possible for small and medium sized ships to have disadvantages financially and avoid calling. In this paper, we estimate the propriety of utilization of crane and labor according to the size of vessels after analyzing time value cost, reflecting the size of vessels, size and number of crane and labor structure, and container handling cost value.

This study is aming at analysing the current trend of container shipping industry before and after COVID-19 Pandemic circumstances. Also, this study offers the political implications for 'the Korean Shipping Nation Rebuilding'. As a result of this study, the several global shipping lines have decreased their ship capacity in response to International Maritime Organization(IMO)'s environmental regulation. This finding is differ from the media reports, that is many shipping companies increased idling vessel to match the lower demand induced COVID-19 pandemic. This study also provides the two implications of the direction about Korean shipping policy. The first one is that the casual relationship of over-vessels' supply and Korea shipping policy is needed to be thoroughly analyzed. The importance of Koreans shipping industry is generally devaluated by most citizens so as to the Korean government should develop the mass media contents to enlighten the less wellknown people regarding shipping industry.

In order to enhance the competitiveness of the container shipping industry and promote its development, based on the empirical analyses using multivariate time series models, this study aims to suggest a few strategies related to the dynamics of the container shipping market. It uses the vector autoregressive (VAR) and vector error correction (VEC) models as analytical methodologies. Additionally, it uses the annual trade volumes, fleets, and freight rates as the dataset. According to the empirical results, we can infer that the most exogenous variable, the trade volume, exerted the highest influence on the total dynamics of the container shipping market. Based on these empirical results, this study suggests some implications for ship investment, freight rate forecasting, and the strategies of shipping firms. Concerning ship investment, since the exogenous trade volume variable contributes most to the uncertainty of freight rates, corporate finance can be considered more appropriate for container ship investment than project finance. Concerning the freight rate forecasting, the VAR and VEC models use the past information and the cointegrating regression model assumes future information, and hence the former models are found better than the latter model. Finally, concerning the strategies of shipping firms, this study recommends the use of cycle-linked repayment scheme and services contract.

IT 기술은 다른 유망산업과 융합되어 새로운 기술과 제품 및 서비스를 생성하여 새로운 시장을 창출하는 버팀목 역할을 수행한다. 우리나라는 2000년 이후 세계 선박시장의 35% 이상을 차지하는 세계 1위의 조선강국이지만, 저렴한 노동력과 과감한 투자를 앞세운 중국과 미래의 선박시장에서 주도권을 탈환하기 위해 새로운 기술 및 서비스 개발에 박차를 가하는 일본과 미국 등의 추격에서 결코 안심할 수 없는 상황이다. 본 고에서는 2005년 이후 조선산업에서 조금씩 비중을 높여가고 있는 IT 기술 개발의 국내외 사례 및 조선시장에서의 기술 경쟁력을 높이기 위한 IT 기술의 역할에 대해 살펴보고 향후 발전 방향에 대해 전망해 본다.

최근 일본 조선업계는 엔고로 약화된 가격경쟁력을 회복하기 위해 다각적인 방안을 강구하고 있다. 한국, 중국 등 해외로부터 선박용 부품의 조달을 확대하는 한편, 기업간 사업제휴의 강화와 생산성 향상을 통한 원가절감에 주력하고 있다. 또한 1990년대 중반 이후에 대형탱커를 중심 으로 노후선의 대체수요가 본격화될 것에 대비, S＆B(Scrapping and Building)방식 및 연속건 조방식을 적절히 활용하여 우회적으로 건조능력을 확대하고 있다. 그러나 대외적으로는 통산마 찰을 우려하여 현재의 총설비능력을 유지한다는 입장하에 설비신증설을 억제하고 있다. 한편 정부차원에서는 조업량 규제 해제, 기존설비규제의 완화 및 암목적으로 기업이 선박건조량을 확대할 수 있는 여건을 조성하고 있다. 이러한 정부시책에 힘입어 기업차원에서는 설비현대화 및 자동화의 투자를 확대하며 고용인력도 증원하고 있다. 이와 병행하여 단기적으로는 가스운반선, 자동차 운반선, 고속여객선 등 고부가가치선종의 수주 확대를 도모하고 중장기적으로는 초고 속선, 초전도선 등 차세대선종의 연구개발을 적극 추진하고 있다.
