The article assesses the level of navigation safety, in theoretical terms, defines the complexity of managing navigational risks in practice. The issues of assessing the navigational safety have been studied due to the importance and relevance of the issue in question, however, due to the great complexity of the problem under consideration, the article considers and indicates the directions for the development of the solution of the given direction, where, first of all, it became necessary to analyze the issue of assessing the levels of navigation risks when navigating vessels of various types in difficult navigation conditions.

In this paper, we survey recent trends of International Global Navigation Satellite System (GNSS) organizations such as the International Committee on GNSS (ICG), International Civil Aviation Organization (ICAO), International Maritime Organization (IMO), and International Telecommunication Union (ITU), and investigate their impact on the maritime and aviation sectors. Each international organization promotes international cooperation, improvement of service quality, assurance of security, compliance with international regulations, and technological innovation and development. ICG develops a variety of satellite navigation enhancement systems. ICAO establishes international aviation regulations and standards to enhance aviation safety and security. IMO establishes international shipping conventions and rules to protect and regulate the shipping environment. Lastly, ITU establishes international communication regulations and standards. Investigation of such international organizations plays an important role in increasing the efficiency and reliability of GNSS systems. Each international organization promotes international cooperation, improvement of service quality, assurance of security, compliance with international regulations, and technological innovation and development. In the future, interoperability and compatibility with new satellite navigation systems and other GNSS and satellite navigation enhancement systems must be secured, so and thus investigation of international organizations must be conducted first.

After World Trade Center's Terror in 2001 and promulgating Maritime Transportation Security Act (MTSA, 2002) and Security and Accountability For Every Port Act (SAFE Port Act, 2006) in the United States, most of the attention on security of international transportation including marine carrier and facility has focused increasingly. Inspection stations in foreign seaport terminal including Busan, South Korea, have been installed by Container Security Initiative (CSI) and Customs Trade Partnership against Terrorism (C-TPAT). The inspection station, however, may directly and indirectly affect delay of truck turnaround time in the seaport, especially high and severe level of security. This paper was analysed a risk for the additional average delay of truck turnaround time incurring by the inspection station under the all level of security, C-TPAT and CSI. As a result of this risk analysis, the higher weighted inspection time based on raising security level, the less number of trucks to be inspected, which will derive high delay in the inspection station.

The subject of navigation has drawn a large interest in the last few years. Navigation problem (or path planning) finds the path between two points, source location and destination location. In smart cities, solving navigation problem is essential to all residents and visitors of such cities to guide them to move easily between locations. Also, the navigation problem is very important in case of moving robots that move around the city or part of it to get some certain tasks done such as delivering packages, delivering food, etc. In either case, solution to the navigation is essential. The core to navigation systems is the navigation algorithms they employ. Navigation algorithms can be classified into navigation algorithms that depend on maps and navigation without the use of maps. The map contains all available routes and its directions. In this proposal, we consider the first class. In this paper, we are interested in getting path planning solutions very fast. In doing so, we employ a parallel platform, Reconfigurable mesh (R-Mesh), to compute the path from source location to destination location. R-Mesh is a parallel platform that has very fast solutions to many problems and can be deployed in moving vehicles and moving robots. This paper presents two algorithms for path planning. The first assumes maps with linear streets. The second considers maps with branching streets. In both algorithms, the quality of the path is evaluated in terms of the length of the path and the number of turns in the path.

The IMO e-navigation strategy has requested a communication infrastructure providing authorized seamless information transfer between stakeholders. The Maritime Cloud is the term used to describe the concept of an infrastructure that support authorized, seamless information transfer, adding those elements, that are necessary to support the e-navigation domain. It is necessary to consider the study on maritime cloud security, but the study is still an early stage. In this paper, we propose a secure synchronization method for the maritime cloud services. The proposed method can be synchronize between the vessel based on the SH-Tree, and it has the advantage that there is no exposure information in the synchronization process.

The value of information becomes very high, a large number of research works has been made for acquiring, managing, and using information. In a specific company (or organization), they are classifying company data documents with managed security levels, and they are securing their secured documents. In this paper, we introduce essential technologies enabling to inspect documents securely and to change specific keywords to normal words, in case that a higher security level document should be converted to a lower security level document.

삼면이 바다로 이루어진 우리나라의 특징상 다른 나라로의 이동은 하늘길과 바닷길로만 가능하다. 외국과의 다양한 교류로 인해 비행기와 배를 이용한 승객 및 물류가 증대하면서 항공 교통량과 해상 교통량은 급속도로 증가하는 추세이다. 항공관제는 해상관제와는 서로 다르면서도 비슷한 측면이 존재하므로 항공관제 시스템을 분석함으로써 향후 해상교통관제의 발전 방향을 살펴보는데 의미가 있다. 본 논문에서는 항공관제와 해상관제와의 차이점, 항공관제 시스템의 구성과 해상교통관제 시스템의 구성을 비교하고, 이를 통해 항공관제 시스템에서 해상교통관제 시스템에 적용할 수 있는 기능을 도출한다.

Smart Security is the global initiative of Airports Council International in collaboration with airports, airlines and governmental agencies. Its main objective is to create a step change in passenger and cabin baggage screening, escalating security costs and constantly evolving threats. Incheon International Airport should adopt and deploy smart security systems not only to strengthen aviation security but also increase passenger's experiences and operational efficiency by way of seamless security screening that it will lead to establish the best security environment to prevent terrorism and acts of unlawful interference.

In recent years, electronic commerce has provided another access for consumers to purchase products. Shopping on line provides much information and less searching cost for customers, but some researches have pointed out that there are difficulties for companies to do business on web. For lack of trust, many people not prefer purchasing through virtual channels. Based on the literature review, this study aims at empirically testing the impact of website design on individual trust in internet firms. From statistic analysis, we will conclude that security, interaction, and navigation functionality will affect on-line trust. The result of this study may provide some managerial implications, especially for firms which want to enter on-line businesses.
