The study attempts to suggest potential problem and solutions expected in the process of implementing KASS, which is currently under development to improve the domestic navigation safety system, and to summarize improvement effects of domestic navigation safety system anticipated by the implementation of KASS. Challenges expected in the process of implementing KASS exists in four aspects: emotional, technical, cost, safety aspects. When KASS is implemented and operates, various benefits can be realized. Benefits include cost savings by not using navigation safety systems during takeoff and landing; reduction of flight delays and cancellations by removing airway congestion; increase of aircraft accommodation capacity; reduction of carbon emissions; preparation for future aviation demands and improvement of air transportation safety; and reduction of flight accidents. In conclusion, it is expected to enter into an era of more intense competition due to increased aviation demands. In order to survive in this competitive environment, early introduction of KASS is indispensable. Analysis results of this study are expected to provide reference information for academic research in this area. A possible future research topic include a study predicting the changes in the navigation safety systems introduced by KASS and proposing practical and useful ways to respond the changes.

New technologies are introduced to recently developed high­technology navigational instruments, and relevant international regulations, requirements and so on have thereby been developed and amended appropriately. These have to be reflected to education and/or training programs for watch officers and masters. In this connection, a syllabus of lectures for the electronic navigation system is proposed by using status analyses of navigational instruments and relevant international regulations and technologies. This can be served as a good reference and help for updating academic programs and detailed scope of examination for the issue of certificates.

The Automatic Identification System (AIS) will provide valuable navigational information to the coastal passenger ship to which RADAR did not cover until now. 112 skippers of coastal passenger ship who are using AIS plotter responded that the AIS is very useful to their safety and they are using the AIS effectively regardless of number of seafarers, ship's speed and navigation time. It is required that all coastal ships should install the AIS to improve the safety navigation in the coastal navigation area.

A walking navigation system (usually known as a locomotion interface) is an interactive platform which gives simulated walking sensation to users using sensed bipedal motion signals. This enables us to perform navigation tasks using only bipedal movement. Especially, it is useful for the certain VR task which emphasizes on physical human movement, or accompanies understanding of the size and complexity of building structures. In this work, we described system components of VR walking system and investigated several types of walking platform by literature survey. We adopted a MS Kinect depth sensor for the motion recognition and a treadmill which includes directional turning mechanism for the walking platform. Through the integration of these components with a VR navigation scenario, we developed a simple VR walking navigation system. Finally several technical issues were found during development process, and further research directions were suggested for the system improvement.

Navigation system is regarded as the interface border line between the Intelligent Transportation Systems (ITS) and the driver as the prospective information provider of the ATIS (Advanced Traveler Information System). Following theory, if the navigation system appropriately designed and utilized, that can maximize the transport efficiency, contribute to improvements of the environments and road safety. To accomplish these dinds of objectives of the navigation system use, human factors plays an important roles specially focused on the driver's safety, performance and system usability. Because the effectiveness of the system depends on the acceptance of the system, and the extent to which the system conforms to driver physical and cognitive limitations and capabilities. Therefore, the ergonomic design vaniables must be seriously selected and reflected in early design step for more effective and appreciate product design. As the first step of this aim, this study selected and categorized the human factors design variables of the navigation system.

The IMO approved e-navigation strategy implementation plan made e-navigation adoption visible. In addition, the schedule for the modernization of GMDSS by the ITU was confirmed at the 4th NCSR meeting. Accordingly, we will complement the existing communication system and provide the requirements for the new communication system to be introduced in the future, reflecting all the requirements for the communication system capable of supporting the e-navigation service. Although the communication method for supporting e-navigation service should be capable of providing IP-based data communication basically, it is impossible to provide internet service because of the narrow-band characteristic in the MF/HF frequency bands. In addition, as the existing GMDSS satellite communication service organization expands and new services are introduced, IP based data communication service will be possible, but service restriction resulting from expensive communication cost can be solved by introducing VSAT service.

Along with the development of information and communication technology, maritime communication systems also have been actively studied for navigation and communication equipment aiming at safety, efficiency, accuracy and security. However, for fishing ship over 100km far from the coast, it is difficult to manage such as location and status of ship. Therefore, in this study, for the safety of the long distance ship through Digital-HF communication system, we use method to choose the optimum frequency and it enables to check the position of ship.

Ship reporting systems are used to exchange information between ship and shore. To realize the digital ship reporting concept, the International Maritime Organization (IMO) recently developed revised guidelines and descriptions of Maritime Service for ship reporting systems in the context of e-navigation. To improve the existing ship reporting system, each Administration should follow the IMO guidelines for ship reporting system. The purpose of this paper is to identify follow-up measures to be taken by the Korean Government as a member State according to the recently developed IMO guidelines in the context of e-navigation, and to present the considerations for the implementation of follow-up measures in Korea. In this study, a ship reporting system in Korea was investigated to identify the considerations for the digital ship reporting system. Consequently, a digital reporting system and digital traffic clearance were proposed and considerations for ship reporting system are presented. This paper is expected to be helpful for the safe operation of ships by presenting the considerations necessary for the implementation of an automated and standardized ship reporting system.

1990년대 말부터 IMO(International Maritime Organization)의 SOLAS(Safety of Life at Sea) 조약에 따라 300톤 이상의 모든 선박에 GMDSS(Global Maritime Distress & Safety System)를 탑재함으로써 전 세계 어디에서나 선박의 조난 및 안전 통신을 위한 육 해상 통합시스템의 기틀이 마련되었다. 최근에는 GMDSS의 현대화와 e-Navigation 개발전략에 따라 해상통신 기술의 디지털화와 음성에서 데이터 통신으로의 큰 변화가 예상된다. 이에 GMDSS 중심의 해상통신 기술현황을 위성, MF(Medium Frequency), HF(High Frequency), VHF(Very High Frequency) 등 다양한 통신 기술에 따라 설명하고 e-Navigation 개발전략에 따라 해상통신 기술의 발전 방향을 살펴보도록 한다.
