By means of analyzing the problems in monitoring plan, design, installation, operation based on maintenance monitoring system installed in subway tunnel section, the methods of improvement were proposed for applying to subway monitoring maintenance effectively in future. The choice of the better monitoring system, the operating method of monitoring system, the confidence and continuity of maintenance monitoring, the performance of responsible monitoring supervision in the phase of the planning of monitoring and design were proposed. The problem and developed plan in the different monitoring systems, the calibration and correction of monitoring system, the analysis for the results and plan for maintenance in the phase of installation of monitoring system and operation were also proposed.

Recently, many kinds of research have been actively developing for a standardization and information to the field of design, construction, supervision, maintenance and management on facilities. The establishment of standard classification system on tunnel facilities and inspection data is most important among the things to have a efficiently maintenance and management. This paper suggests standard classification system on tunnel facilities and inspection data, and, on the basis of that, code work with standard classification system and input work was practised. The purpose of this paper is to suggest a kind of statistics data and investigate a characteristics of inspection using statistic data on railway tunnel.

We are generally applicate smoke control only vestibule about special escape staircase, it is one of some smoke control model of NFSC 501A. But there are some point at issue in this system. The smoke control system on supervision field of writer is smoke control only vestibule same as the other resemble field. Writer studied in the concrete to find a solution at this issue, and derived a conclusion the most reasonable system on the field is "same time smoke control for staircase and vestibule" by the engineering analysis considering stack effect.

MET is one of the few physical therapy having its own criteria. Mr. Holten approached the Norwegian Health Authority in 1967 to get his MET System recognized as a treatment method of its own. He was granted his approval for his exercise system's specivic criteria connecteed with the treatment method. In MET, the patient exercises himself without manual participation by physiotherapists, however, under continuous supervision.. The apparatus should be designed that functional quality (arthrogenous, circulatory, respiratory, neuromuscular) in question is optimally influenced when the patient carries out exercise in a certain range against a graded resistance. The therapy reassesses the scheme of treatment at least every fifth session and the maximum number of patients being 5 person per hour. The important principles in medical exercise Therapy are stabilization of hyperfunction through the system of autostabilization and mobilization of hypofunction through automobilization. In MET excrcises are adjusted to the patient's reactions. MET equipment is therefore made to meet requirements for treating patients with painful pathological dysfunction in the musculo-skeletal system.

This study was to suggest the necessity of depth research in order to enhance the effectiveness of technical consulting system. And the purpose of this study was to decrease the construction accidents to some extent, being on the increase day by day as it takes issue properly and suggest a reform measure. As for research method, it executed the collection of public opinions widely and questionnaire with the bibliography, expert of construction safety, the related institutions, academic world, safety association, and director of construction site. Also, it was to suggest the reform measure by the stage, classifying the problems on the system and operation by 4 stages like a stage of delivery of subscription and supervision, a stage of contract with guidance of technology, a stage of executing the guidance work of technology, and a stage of performance of advice.

There are two major operation and management (O & M) systems in Korea, one by the Korea Agricultural and Rural Infrastructure Corporation (KARICO), a government corporation, and the other by non-KARICO, which includes Irrigation associations (IAs) and individual farmers under the supervision of city or county authorities. Main issues and constraints in the irrigation facility management are: (1) The dual system of the irrigation water management system; management by KARICO and that by IAs, and (2) From the commencement of KAICO in 2000, farmers were exempted from water charge. This is opposite to the international trend, which follows' user pay principle: Main specific strategies to improve irrigation management system are: (1) Introduction of water metering for water charge as well as water conservation, (2) Adoption of demand-oriented irrigation rather than supply-oriented to reduce waste of water, (3) To augment farmer's participation by forming water user associations, (4) To maintain consistency of government policy, (5) To promote roles of local governments, and (6) To reestablish the role of KARICO.

This paper proposes a fault detection and recovery mechanism for a fault-tolerant Mini-MAP system, and provides detailed techniques for its implementation. This paper considers the fault-tolerant Mini-MAP system which has dual layer structure from the LLC sublayer down to the physical layer to cope with the faults of those layers. For a good fault detection, a redundant and hierarchical fault supervision architecture is proposed and its implementation technique for a stable detection operation is provided. Information for the fault location is provided from data reported with a fault detection and obtained by an additional network diagnosis. The faults are recovered by the stand-by sparing method applied for a dual network composed of two equivalent networks. A network switch mechanism is proposed to achieve a reliable and stable network function. A fault-tolerant Mini-MAP system is implemented by applying the proposed fault detection and recovery mechanism.

During the last two decades, we experienced a few of the energy shocks and felt the importance of the energy saving seriously. As our energy reliance on other countries is absolute. We must counter these situations nationally. To save the electric energy, various methods are explored such as the moderation of motor capability, the use of high efficiency system, the supervision of lighting systems, demand monitoring control systems. In this study, we develop a system for electric power energy saving. In Case the receiving point voltage is higher than the required voltage, the system reduce the voltage to an allowable level and by doing so it saves energy and protects the equipments from over voltage.
