최근 AIS 기술을 적용한 MOB(Man Overboard) 장치가 개발되고 있으나 이에 대한 국제적인 기술표준 뿐만 아니라 우리나라의 기술기준도 아직까지 마련되어 있지 않다. MOB가 사용하는 주파수가 AIS 주파수와 동일하기 때문에 AIS VDL(VHF Data Link)에 미치는 영향이 파악되지 않았기 때문이다. 본 연구에서는 AIS 기술을 적용한 MOB가 AIS VDL에 미치는 영향을 분석하고 기술기준을 마련하는데 있어서 고려해야 할 사항을 제시하였다.

To achieve this study, this study divide career orientations of AIS user into technology and management and group job characteristics into variety and autonomy and is to verify an effect of two factors on system performance (AIS satisfaction and use). The results of this study are as follows. First, there is a positive effect of the relevance between technology orientation and autonomy on AIS satisfaction. Second, there is a positive effect of the relevance between management orientation and job variety on AIS satisfaction. Third, there is a positive effect of the relevance between technology orientation and autonomy on AIS use, and finally, there is no positive effect of the relevance between management orientation and job variety on AIS use.

Recently, marine accidents such as the sinking accident Mongol freighter ship and the sinking accident of Sewol ferry in Jindo continuously happen. In order to decrease the number of these marine accidents, Korean ships are obliged to follow the AIS(Automatic Identification System) system. The AIS protocol includes all information for sailing ships. However, the standard AIS protocol does not provide any security function, In addition, it is possible to hijack the standard AIS protocol in case of using a satellite communication device called FUNcuve Dongle Pro+. Therefore, this paper analyzes weak points of the security in the standard AIS protocol. Furthermore, this paper ensures reliability by marking the MAC Address of sender and receiver for secure communication and suggests the protocol that can securely send data, using the VPN Tunnelling method. Therefore, the suggested AIS protocol provides the secure communication to the AIS protocol and protect the messages in the AIS protocol, which can serve safe voyages by decreasing the marine accidents.

The more larger and heavier the ship, the more accidents happen in the ocean and coastal area. The IMO, IALA and ITU finalized the technical standardization process regrading performance standard and technical characteristic of Universal Ship-borne AIS. Korean government are going to setup AIS system in the coastal area in three years. To construct AIS service efficiently in Korean water, The authority should consider requirements about several things. This paper presents the consideration of our domestic AIS in view of investigation of international standard and requirements of ours.

The current AIS network and. system are run on a full scale with 22 ground stations and. 11 operational systems, completing a nation-wide, integrated network However, currently it needs to manage sea traffic by linking AIS to VIS which 1vs a limited service area due to restricted radar detection zones in harbors or coastal areas. Accordingly this study analyzes the current status of the AIS system and. proposes technological and. operational improvement plan of the current AIS system through investigating the actual conditions of the AIS system and. its operations.

Sharing both locations and positions of ships makes it possible to utilize critical item for their safe and efficient navigation in such diversifying meantime environments. AIS is the representative technology for the sharing solutions. The AIS is even used in airspace and ground stations, so that AIS could facilitate the ships' safety navigation and their prevention/rescue from endangers. Due to AIS's many advantages, IMO(International Maritime Organization) made adapting the AIS mandatory for international passenger ships and the ships that are over than 300 tons. AIS uses VHF band areas for transmitting information and the information can be propagated to several hundreds km in range. Due to the large range, AIS monitoring system can acquire huge number of ships, which makes system performance lower and busier. In this paper, we propose the strategy of AIS information extraction for efficient monitoring system. Thus, the monitoring system has higher processing performance and lower network usage. As well as, the proposal affects the monitoring system has more capacity to include other systems' targets, in result.

This study is to analyze the effect of compatibility of information characteristics and information technology structure on AIS performance. This used financial and non-financial factors as the characteristics of management accounting information and used information technology structure as centralization and decentralization classified by Ahtuv et.(1989) and Fiedler et.(1996). 425 sampling companies are selected randomly and 137 of them were used in this study. The results of this study are as follows. First, In compatibility analysis between the characteristics of management accounting information and information technology structure, in case of companies which have centralized data process system, AIS performance of companies which use financial information is higher than that of companies which use non-financial information. However, no meaningful results show statistically. in case of companies which have decentralized data process system, AIS performance of companies which use non-financial information is higher than that of companies which use financial information. Also the statistical results show the meaning at the p. < 0.01.

In this paper, we analysed the technical characteristics of a universal shipborne automatic identification system using self-organizing time division multiple access in the VHF marine mobile band. IMO's Marine Safety Committee approved revision of chapter V of the Safety of Life at Sea(SOLAS) Convention in 73rd meeting. According to this revision, AIS will become a nandatary carriage requirement by 01 July 2002. AIS is a broadcast system, operating in the VHF marine band. It is capable of sending infomation such as would be beneficial to the safety of navigation and the identification and monitoring of maritime traffic. It is absolutely necessary to analyse the related international and domestic specifications for the AIS implementation and installation.

Recently, one of important resolutions of IMO MSC is an adoption of AIS in SOLAS Chapter 5. The AIS, which is a communication system to enhance safety of navigation by transmitting and receiving vessel information automatically, entered into force on July 1st, 2002. This paper provides guidelines for utilizing AIS effectively and successfully in VIS or all ships. For this, we investigated technical characteristics of AIS, the regulations related to AIS, marine accidents.
