Now society has been extending to ubiquitous information society under the information telecommunication facilities. So it is importance to install and design those for the core business. If there is a serious problem on the information telecommunication infra-facility, it could be seriously effected to the life of the people and the national economy. To prevent the those problems, information telecommunication infra-facilities have been installed/supervised due to the proper telecommunication specialists. In this paper, firstly invested the current supervision system and then proposed how to upgrade information telecommunication services through the proposed supervision system for the telecommunication infra-facilities.

The International Civil Aviation Organization(ICAO) recently established the Global Aviation Safety Plan(GASP) for national aviation safety management, along with the enactment of Annex 19, Safety Management System(SMS). ICAO require the establishment of the 'States Safety Programs(SSP)' for countries with excellent safety evaluation, including Korea, and the establishment of aviation safety supervision systems for all Contracting States by 2017 under the enactment of ICAO Annex 19. Required. The Ministry of Land, Infrastructure, and Transport has continuously invested in R&D to secure such aviation safety systematically, and is making efforts to develop and disseminate related technologies by establishing long-term R&D roadmaps. A study on aviation safety supervision among the system-based aviation safety supervision support technology development R&D project, which is underway as part of the aviation safety technology development project of the Ministry of Land, Infrastructure and Transport. We conducted a study to see if this methodology logically guarantees reasonableness.

Since Intelligent Transport Systems(ITS) is a complex project combining technology and system of transportation, information and communication and civil engineer, it needs a specialized management activities. However, it is difficult to judge who has responsibility for a shoddy and fault construction since the role between project management and supervision is very ambiguous. The aim of this study is propose an efficient project management and supervision for ITS reflecting the characteristics of ITS. Therefore, we suggest a statistical models using nonlinear regression model to prepare the project management and supervision compensation criteria, hence, we choose the realistic and validation statistical model.

A hierarchical Petri- net is utilized in supervising an automated vehicle system, The supervisory system is supported by computer networking in order to facilitate necessary processing, and consists of control flow level and computer allocation level so that a designer and an operator can easily build and/or access to each level. There are two modes of utilizing Petri net here in this paper. One is to employ it in designing the control system, in order to optimally allocate computers in every stage of processing. The other is for supervision of the system in operation, in order for the operator to be in a easy-to-comprehend environment of operation. The effect of these two modes of utilizing Petri net is examined.

With the cognition of the problems on propulsion system of rural development program, the requirement for accurate diagnosis of the problems and for reform scheme is increasing. This study was performed to solve the above requirement especially on the level of a local government, Chungnam province as an instance. For accurate diagnosis of the problems, the present situation of propulsion system, i.e. organization and governance, planning and policy making, implementation and supervision of rural development program was investigated, and the cognition of public officials and specialists was surveyed. From the study, it showed that the problems of propulsion system for rural development program in Chungnam province are duplication of work sphere among departments, formal administration of governance, an absence of long-term plan with vision and strategy, and absence of department in charge of comprehensive supervision and so on. As a result of the study 9 reform schemes to solve the problems were suggested.

As there are more accidents which are more serious in construction site than other industries, it needs the safety management system to be SLIM on the same time, there are still lots of difficulties to prevent those accidents exactly, so it also needs a safety supervision team to prevent the accident, unsafe operation and condition before happening, which is also called as a Man-to Man safety management method. The range of the job site in one personnel's management is very big and large, so it needs the personnel to deep watch the safety operation and prevent any unsafe/fire accidents; the personnel also should find out the unsafe points in the job site, and carefully supervise the dead angle site, then support the totally safety management POINT and realize the ZERO accident.

This paper describes the procedures and results of an acoustic emission testing performed during hydrotest of spherical pressure vessel for propane storage. A computer based multi-channel real time monitoring and source location analysis AET-4900 system was used for AE testing. The vessel was extremely quiet throughout the entire test run and especially 6 to $14.5kg/cm^{2}$, it is normal operating pressure range. After exceeding $14.5kg/cm^{2}$, one of the 20 sections showed the most event in any one section 11 total but there were scattered at different locations. In order to confirm the events seen in horizontal weld line of that section, proof testing was performed with ultrasonics and radiography.

The range of the job site in one personnel's management is very big and large, so it needs the personnel to keep watch the safety operation and prevent any unsafe/fire accidents. Also the personnel also should find out the unsafe points in the job site, and carefully supervise the dead angle site, then support the totally safety management POINT and realize the ZERO accident.

This study focuses on the trends and issues of improving safety management of elevators in Korea. Frequency and severity of accidents in relation to conditional pass in periodic inspection, maintenance, market surveillance are analyzed based on the statistical data and social cost due to a variety of related fields in managing elevator safety was estimated first. The results of statistical analysis performed in this study will provide logical basis and future direction for improving the safety management system. The role of certification and supervision is particularly addressed to reduce the related accidents and the social cost. The effectiveness of such procedures can be found from the results of simple statistical analysis.

The current railway control system in Korea is comprised of signaling, electric rail power, communication, and maintenance systems that are independent of each other. Further, these systems have different mediums and protocols for transmitting the field equipment data to the central control system. The Safety Supervision System has as its purpose the collecting of safety-related data from each system to predict and prevent accidents, this system utilizes standard protocol. Safety-related data need to be collected from field data transmission devices of the existing control system, the data should be collected without affecting the communication of the existing system. In this study, sniffing skill, which is typically used for network traffic monitoring or security, is used to collect data. The problems arising from the use of sniffing devices are noted, and the Packet Conversion Node is proposed as a solution to the problems. Further, functional and performance testing were completed for the prototype, and the software architecture and packet conversion process were verified.
