The interpolation of missing AIS data can be used for recovering the lost data of a ship's state which is then able to produce useful information for VTS stations or other ships. Previous research has introduced some interpolating methods however there are some problems with regard to missing AIS data. This paper proposes one new method which includes linear interpolation, cubic Hermit interpolation and an identification mechanism to overcome some of those limitations, first AIS data regarding ship position, COG, SOG and HDG is divided into separate time series, then the characteristic of the missing data is investigated into through using an identification mechanism, an appropriate interpolation is selected to fit all the time series which matches the characteristics. Numerical experiments are carried out using real AIS data to validate the algorithm of this approach and the results are compared with the previous method, after which the actual missing area is suggested to be interpolated by the proposed method. The interpolation results show this approach can be applied well in practice.

In offshore, various external forces such as wind force, tidal current and impulsive breaking wave force act on offshore wind tower. Among these forces, impulsive breaking wave force is especially more powerful than other forces. Therefore, various studies on impulsive breaking wave forces have been carried out, but the soil reaction are incomplete. In this study, the p-y curve is used to calculate the soil reaction acting on the offshore wind tower when an impulsive breaking wave force occurs by typhoon. The calculation of offshore wind tower against impulsive breaking wave force is applied for the multi-layered soil. The results obtained in this study show that although the same wave height is applied, the soil reaction generated by impulsive breaking wave force is greater than the soil reaction generated by wave force.

Recently, the fierce competitions in the shipping industry and the global economic downturn have heavily influenced ports' operational strategies. In order for port authorities to remain competitive at an international level and to provide more accurate information to develop National policies, ports are required to analyse and improve operations' efficiency. In this paper, the efficiency of 19 Italian ports in 2013, handling different types of cargoes, is assessed through the application of Data Envelopment Analysis (DEA), with constant return to scale (CRS) and variable return to scale (VRS). The purpose of this study is to analyze the efficiency of Italian ports and evaluate whether differences in size and specialization of each port (or cargo handled) are directly correlated with ports' efficiency.
Evaluating the Effect of the Corporate Social Responsibility (CSR) on Corporate Image and Reputation in the Shipping Sector
Jang, Hyun-Mi ; Kim, Sang-Youl ;

This research seeks to improve the understanding of corporate social responsibility (CSR) and its advantages in the shipping sector. Recently, an improved emphasis on CSR, which incorporates environmental and social concerns into economic considerations of firms, can be found in business management and marketing literature. This is mainly because of people's increased awareness in regards to the negative consequences of corporate activities such as increased environmental pollution and gaps between the rich and the poor. According to the previous literature, it has been revealed that responsible actions by companies can generate positive outcomes in terms of financial and time aspects, but more importantly, intangible equity of the company, including improved corporate reputation, image as well as brand. As the regulation is intensifying in regards to environmental and social responsibility in the shipping sector, shipping companies are trying to engage in CSR to gain competitive advantages. While the reputation and image of shipping companies play essential roles for developing sustainable maritime transport, few studies have been conducted for how the CSR of shipping companies influence the shipping companies' reputation and image relative to other industries. In this regard, this study aims to investigate the effect of the corporate social responsibility on corporate reputation and image of shipping companies on the basis of an exploratory study in the Republic of Korea. This research would be beneficial to both academics and practitioners for developing useful CSR strategies which could promote the public's recognition of the shipping sector.

According to the globalization of world economy on distribution and sales, logistics and transportation parts are playing an important role. Especially, they have to decide what is the key factor of route choice model and how to choose the right transport route in multimodal transport system. By considering the key factors in rote choice model for freight forwarders between Mongolia and Korea, this paper propose 4 main factors: Cost, Delivery time, Freight and Logistics service with 13 sub factors. The importance of factors is surveyed base on AHP through interview with freight forwarders. In results, the empirical insights about current status of Mongolian forwarders are provided with different factors between transportation modes. Expecially, the Time factor is a role factor to choose transport route for air transportation forwarders.

Sea-ports in Northern Vietnam have experienced a rapid growth of container throughput in recent years. To accompany with such development, huge investment also has been performed to enhance not only local port capacity but also the regional logistics system. Container terminals in Northern Vietnam locate centrally along Cam river of Haiphong city, leaving 2 others in Quang Ninh province. Five out of totally 11 container terminals in the area are under the control of Vinalines - a national corporation in field of maritime industry. In this paper, those terminals are classified in terms of location and ownership. The volume of container throughput and facilities of all container terminals in Northern Vietnam from 2005 to 2014 are recorded in order to compare the performance of groups. A Data Envelopment Analysis (DEA) is then applied to evaluate the relative efficiency of such terminals. Before conclusion, number of suggestions will be contributed to related parties.

The expansion on the scale of international trade and rapid economic growth in Northeast Asia have caused intense competition among global companies for securing international logistics center in Northeast Asia. Analyzing location competitiveness for international logistics center in Northeast Asia, this paper aims to extract implications for enhancing locational competitiveness. Employing the relative importance among location selection factors extracted from AHP analysis in prior study, we evaluated the major five port-cities in Northeast Asia including Busan, Gwangyang, Shanghai, Qingdao and Tokyo. In the evaluations, Shanghai (3.926) ranked as the first, followed by Busan (3.859), Qingdao (3.555), Tokyo (3.013) and Gwangyang (2.915). Furthermore, the causal relationships between determinants for location choice decision (logistics factor, cost factor, market factor, service factor and environmental factor) and dependent variables (competitiveness of international logistics center, potentiality to growth, present intention to move into and future plan to move into) were analyzed to provide implications. Results provide useful insights for further improvements, and helps strategic agenda for future development of port-cities.

The purpose of this paper is to analyze maritime piracy and its economic implications with particular attention to attacks registered in the Gulf of Aden, The paper also aims to investigate how the International community, along with Sovereign States, should allocate resources in order to make the seas a safer place and describe how closely inter-related maritime piracy, preventive and punitive measures put in place by Governments are. Elements of economics and ergonomics are taken into account in order to properly investigate the major legal issues relating to maritime security. The paper proposes a cost-benefit analysis in order to investigate in theory what is the rationale behind engaging in criminal behavior and recommend some solutions to the issue to be undertaken by the International community. It is concluded that in order to cost effectively fight piracy, a mix of more coordinated National and International laws, standardized and increased punishment levels among jurisdictions and extended patrol controls are needed.
