The depleting fishes resource and water pollution in coast has a decisive effect on the fish farm and fisheries. For solving these problems the fish farms are moving to the offshore. The fish farms in offshore have to design the strong mechanism as compared with cost's fish farm, and operate by the remote feeding system and monitoring system for safety and management.. This paper describes a remote feeding system for fish farms in offshore. The amount of feed is depending on temperature and fish weight. The fish farm temperature is changed extremely in offshore than on land side. This paper described that the feed amount is calculated automatically according to temperature and fish weight, and the remote feed system. The performance of remote feed system is tested with model.

After the introduction of the topologically structured geographic information system(GIS) with relational DBMS, the attribute data can be handled without considering locational data. By utilzing of the characteristic of the relational DBMS, it can be used as an expert system building tool in GIS. The relational DBMS of the GIS furnishes the data needed to perform deductive functions of the expert system, and the rule based approach provides the decision rules. Therefore, rule based approach with the expert judgement can be easily combined with relational DBMS.

The broadcasting system for the customer safety and conveniency is one of the important convenience facilities taking charge of customer guidance, emergency situation broadcasts for the people waiting at the platform, waiting lounge and train approaching broadcasts. To maintain this broadcasting facility local management control system(LMC) is needed. LMC observes operation status of the facility components which is set up at station and the observation results are confirmed through out remote management PC installed in the jurisdiction branch office. The staff only observes and confirms the errors of the electrical power source at broadcasting facility components accordingly the real mechanical troubles are detected by on-the-spot survey. this paper deals with existing broadcasting system only acting as a simple observation function and the research of LMC function extension which controls, monitors and tests broadcasting facility.

The appearance and popularization of Internet changes the existing restrictive management system into the new management system on Web. In this paper, We developed real-time management System controlling all sorts of informations from remote experiment system. Informations from Web client is stored for DB and Wherever User can use Internet, User can get this informations. We also developed Editor modifying Client Display.

The prototype of forest fire management system on Web was studied. In the architecture of this system, one of the most important concerns is to handle load upcoming to Web Server so that it provides Web service without any delay or failure. In order to solve this problem, the agent is designed on dispatcher in a Web server cluster and implemented to distribute load dynamically by considering the information related to load coming to the Web Server such as the number of connection to the Map Server. The proposed forest fire management system has user-friendly interface with the GIS mapping functionality by selecting Map Objects Internet Map Server (MO IMS) as Map Server and is implemented using Java as programming language.

The Measurement of risk parameter in city-gas equipments have been measured and confirmed by human, and evolved into remote monitoring system using wireless communication. Furthermore, domestic and international industry increase the efficiency of management, which can develop remote monitoring and control system using wireless communication. However, Those wireless system might be decrease the efficiency and ease because of connecting PDA and lap-top using wire-cable when data have checked immediately from outside. This paper is able to improve efficiency of safety management on city-gas equipments by developing mobile city-gas safety management system on AR.

Currently there are many standards of network management. They are: SNMP(Simple Network Management Protocol - for Internet management), CMIP(Common Management Information Protocol - standardized by ITU-T and ISO), RMON(Remote network MONitoring - for distributed management of the LAN segment), and so on. Especially RMON has created the many concerns in order to manage subnetworks of a large network, but it has negative aspects. For instance, routers or hubs with RMON capability are expensive to a network manager because of adding heavy management cost. Moreover it imposes a heavier burden on network manager, because it must use a network management tool which will be additionally needed with RMON device. This paper proposes a model of PC based RMON Agent system. The RMON Agent system monitors the traffic on LAN segment through the use of a Virtual Device Driver(VxD), based on PC. In term of cost this model will replace the expensive RMON device, and eventually enable a network manager to manage LAN segment more efficiently, due to reduced cost.

Existing wire based physical security system solutions show limitations in time and space. In order to solve these deficiencies, a remote physical security system has been implemented using smart phone based on mobile cloud computing technique. The security functions of mobile cloud computing technique include mobile device user authentication, confidentiality of communication, integrity of information, availability of system, and target system access control, authority management and secure hand off etc. Proposed system has been constructed as remote building management system using smart phone, and also has been efficient to reduce energy cost (5~30%), result of system average access and response time 7.082 second. This systems are evaluated to have high efficiency compared to performance.

These days due to the introduction of the subject classroom system, the classrooms for the subject are arranged and various advanced educational equipment is provided in the classroom such as the actual object image processor, electronic blackboard, and educational photographer which are helpful to the class. With the increase of these equipments, the number of remote controller of individual educational equipment also increases, therefore it is complicate to manage the remote controllers and teachers need to learn the usage of them. So the system supports a remote control for managing the educational equipment by the one remote controller and the instructional supplement. The system consists of the hardware which is similar to popular remote controller and the software which is installed on the teacher's PC and supports controlling the educational equipments, recording the instruction, writing on the blackboard, and automatic power off of the equipment. By introducing the system the teacher could reduce the time consumed by the equipment's control and useless electric waste.
