  • S-57 포맷으로 기술된 전자해도는 바다에 대한 디지털 지도로서 해안선, 수심, 항로표시 등과 같은 다양한 정보를 표현하고 있다. 이러한 전자해도는 주로 선박의 항해라는 특수한 목적으로만 사용되어 왔고, 전용의 시스템을 통해서만 이용할 수 있는 단점이 있다. 또한, S-57이라는 특수한 포맷으로 기술되어 있기 때문에 다양한 활용이 어렵다는 문제점을 가지고 있다. 이러한 전자해도를 손쉽게 이용하고 해양정보시스템의 기반 데이터로 활용하기 위해서는 범용의 표준 포맷으로 변환할 필요가 있다. 이러한 범용 표준으로 OGC(Open Geospatial Consortium)에서는 지리정보를 효과적으로 표현할 수 있는 XML(eXtensible Markup Language) 기반의 GML(Geography Markup Language) 표준을 발표하였다. 이에 본 논문에서는 선박의 항해에만 제한적으로 사용되던 전자해도를 손쉽고 다양한 활용이 가능하도록 GML로 변환하고 관리하는 방법을 제한한다. 즉, S-57 포맷의 전자해도를 GML 포맷으로 변환하고, 변환된 GML을 데이터베이스로 관리하는 시스템을 설계하고 구현하였다.

  • Major nations undergone grand national strategy regarding Eurasia such as China's One Belt and One Road Strategy and Korea's Eurasia Initiative owing to Eurasia's regional importance. Korea's Eurasia Initiative aims to make one continental, creative continental, peaceful continental with intra-Eurasian nations as grand national strategy is based on creative economy, undertaken by President Park's Government for the future of Eurasia after the Northeast Asian logistics hub strategy. Eurasia Initiative includes logistics network project as an important one which consists of Eurasia Friendly Express, Rajin-Hassan logistics project, the Arctic Ocean route project and Rail transport network project. The success of Eurasia Initiative depends on North Korea. The purpose of this paper is to contribute to the improvement of prompt logistics network by networking main rail transport and other transports such as inland waterway transport and air transport by studying the current situation of Eurasia Express project, including rail transport network and the efficient methods of Eurasia logistics. The efficient methods of rail transport network under the Eurasia initiative are construction of multimodal logistics network connected with rail, international cooperation for logistics standardization in Eurasia, Eurasia nations' subscription of logistics-related conventions and projects performance based on these conventions, etc.

  • This paper reviews the Interpretative Guidelines on EU passenger rights regulations in the context of the developing situation with COVID-19 of EU commission. To enlighten the obscurity and to mitigate the economic impacts of the COVID-19, European Commission has published "Interpretative Guidelines on EU passenger rights regulations in the context of the developing situation with Covid-19" on March 18, 2020. The Guideline essentially aims to create a coherent system of rules to assist the passengers, industry and national authorities overall under the unprecedented circumstances across the European Union. To do so, the Guideline is drafted to cover the rights of passengers travelling by air, rail, ship or bus/coach, maritime and inland waterways, as well as the corresponding obligations for carriers. From an aviation industry focused perspective, by referencing the Regulation (EC) numbered 261/2004, the Guideline specifically applies to cancellation and delay in flights which are seen as the dark spots for the air carriers concerning potential burdens.

The research methodologies such as literature survey, O/D analysis are adopted in the study. The following several conclusions can be suggested. Firstly, in port logistics system the dredging in navigational channels and in Kumgang Dam and the incentive schemes for the shipping companies and the international freight forwarders are required. Secondly cargo inducement schemes should be introduced to induce container cargoes originated in Junbook Do Province and adjacent area etc. Thirdly the development of new shipping routes and strengthening the coastal routes among domestic sea ports. Fouthly establishing supply chain management system with adjacent Chinese Provinces such as Shandong.

  • The existing vessel monitoring system using the ground surveillance radar has a difficulty in monitoring ships continuously due to the limited range of detecting ships. For resolving this problem, we carry out a research on ship detection which is to be the core technology of vessel monitoring system for ocean monitoring using SAR imagery. There are two different methods of detecting ships in SAR imagery: detection of the ship target itself and detection of the ship wake. In this paper, we mainly focus on algorithms which detect the ship itself, and also present the accuracy test after extracting positional and directional figures of the ships. After rectifying input SAR imagery using polynomial transformation, we use Wiener filter to remove speckle noises. A labeling technique and morphological filtering in conjunction with Otsu's method are used to automatically detect the ships based on the image processing domain. For ground truth data, information from a radar system is used, which allows assessing the accuracy of the proposed method. The results show that the proposed method has the high potential in automatically detecting the ships and its positional/directional figures in a fast way.

  • Ships and marine structures(lighthouses and buoys for AtoN) have AIS(Automatic Identification System) for transmission messages which include navigational and environmental information. VTS Center and surrounding ships receive and apply the information to safety navigation. A main characteristic of AIS messages is open to general people, so many researches are in progress. In this paper, we design an information management system which considers marine vessel traffic and environmental information in korean littoral sea. The system gathers and processes the information, and stores the processed data to multi-stage database. Also the system visualizes the stored data to use analysis and statistics based on ENC.

  • In this paper, we analysed vessel traffic volume and patterns of traffic flow for ships using areas where included wind farm site and adjacent waters of Daejeong Offshore Wind Farm, and estimated traffic volume by classified navigational routes according to suggestion of rational routeing measures on the basis of classified patterns after installation of offshore wind facilities. Also, we assessed vessel traffic safety for each designed routeing measures on the basis of estimated traffic volume and proposed requisite countermeasures for the safe navigation of ships. With a result of analysing patterns of traffic flow, the current traffic flow was classified by 8 patterns and the annual traffic volume was predicted to 8,975 ships. On the basis of these, expected the vessel traffic volume according to designed four routeing mesaures after installation of wind farm. As result of assessing vessel traffic safety by using powered-vessel collision model of SSPA on the basis of the estimated traffic volume, the value of collision probability was less than safe criteria $10^{-4}$. Thereby we made sure usability of the designed routeing measures for the safe navigation of ships.
