About 50 percent of irrigation and drainage facilities in our country are deteriorated as they were constructed over 40 years ago. Worsening the problems in function might be caused by these facilities' constant exposure to the elements. With these reason, efficient maintenance and management of irrigation and drainage facili-ties are required. A computerized system is tailored on the basis of the each characteristics'data of irrigation and drainage facilities. The unified management system to be introduced in this study is a package program consisting of three subprograms. Facility Management(FM) system, the first component, is a relational database system for image processing and registering the characteristics of irrigation and drainage facilities. The objective of this program is to manage the ledger of each facilities and to scan the characteristics of facilities. Telemeter(TM) system, the second component, monitors and processes the data from the sensors statistically. This system is preprogramed for the complete design of TC/TM system. Hydrological Data Management(HDM) system, the third component, executes the hydrological analysis using meteorological data. The unified management system can provide the latest information, such as image data, lists and items of facilities, and items of reforming and rebuilding etc., of the facilities to the manager. At the same time, this system can manage hydrological and meteorological data in realtime.

The creation of favorable water space, in our living circumferential space, is a very important factor to offer rural scenery to neighbor residents. In other to arrange stream landscape, we developed Stream Landscape Simulation System(SLSS). SLSS is combined with image and database rotationally. SLSP system creates composed simulation image overlaying both background and landscape image. This system is to compare and estimate original landscape image with simulated one. SLSP system needs continuing development and buildup of Unified Relational Image Database(mm) to design of various landscape.

The creation of favorable water space, in our living circumferential space, is very important factor to offer rural scenery to neighbor residents. We are to introduce stream landscape arrangement technique considering favorable water environment against conventional methods. In this study, the modeling district is Seungdu small stream of Ansung river system in Pyung-Teak city, Kyonggi province, and we carried out stream landscape simulation. The arranging plans of landscape are classified ti three types. The first one is conservation type of ecological environment that can express natural characteristics of stream inherence, raise variety of living things and construct coexisting environment between human beings and the other living things. The second one is favorable water approach type. The basic object of this type is space construction for easy approach to waterside and increase of comfortable feelings of spectators. The third one is water utilization/flood control management type. In planning of environmentally favorable landscape arrangement, this type is the most important but is likely to be ignored. This type is an arranging plan of stream landscape considering safety. Also, we developed Streams Landscape Simulation System(SLSS). This program can be used for comparison of original landscape image with simulated one. To apply SLSS on the interested stream, landscape simulation that is based on hydraulic characteristics, runoff, flow direction, detailed conditions of basin and ecosystem of stream have to be executed. In this point, developing a stereographical technique of image processing and exact study of applying plan have to be executed continually.

N/A The methicillin resistant Staphylococcus aureus (MRSA) strains can produce clinically serious infections. Recently, MRSA infections have had very important clinical significance because of the increasing incidence of MRSA infections and the resistance of MRSA to various antimicrobial agents. The purpose of this study was to evaluate the clinical aspects of MRSA infections treated at Yonsei University Severance Hospital from Jan. lst, 1986 to Dec, 31st, 1987. The results are as follows: 1) The incidence of MRSA isolated was 27.8% of the total Staphylococcus aureus isolated. It was found to be present at frequent of 38.6% in sputum, 23.9% in pus, 38.6% in urine and 18.2% in blood. 2) The sites of MRSA infections were wouod infection (51.2%), pneumonia (25.2%), sepsis (8.1%) and urinary tract infection (8.1%). 3) The risk factors associated with MRSA infection were previous use of antimicrobial agents (80.9%), previous operation (69.7%) and previous care in an intersive care unit (50%). The diagnoses at admission in patients with MRSA infection were trauma (30.3%), neurologic disease (12.3%), disease of the reapiratory system (11.5 %), oncologic disease (5.7%) and burn (4.9%). 4) The treatment failure rate of MRSA infections was 35%, the mortality rate of MRSA infections was 12%. 5) According to in vitro susceptibility tests, sensitivity to MRSA was 100% for vancomycin,99% for fusidic acid, 88% for sulfamethoxazole-trimethoprim,27 % for clindamycin,25% for amikacin,3% for tobramycin and 3% for gentamicin. This study suggests that MRSA infection can be decreased by early recognition of the risk factors associated with MRSA infections, administration of adquate antimicrobial agents and detailed epidemiologic surveillance.

The arrangement of small streams in rural area, in the past times, attached importance to the prevention of flood damage through the straightening and lining of streams. Recently, the way of small stream arrangement is introducing the idea of water friendly environment or friendly space. As a result, there has been much concern with water favorable river management model which may lead to control flood. However, it is very difficult to develop a model applicable to all types of rivers, since each river has different flow velocity, flow amount and unique ecological characteristics. In this study, photo processing technique, one of landscape simulation methods, has been adopted because it helps to visually express and comprehensively evaluate pre and post scenery and easily applicable. Some important guideline and technique for the planning of small stream landscape arrangement are mentioned in this study. The simulation system for acquiring water favorable space and arranging landscapes needs to develop database which can forecast various types of landscape. It may also be used for the bases of planning and designing river environment arrangement. Computer aided image processing system enables to make selective planning in river environment arrangement. It may also enables to develop the methods for river environment development, ecology conservation, and multipurpose space utilization. Moreover, it makes economic river arrangement by applying river environment arrangement methods relevant to geographical characteristics. There are some limitations in this study, such as shortage of exact investigation on the stream direction and velocity in landscape arrangement. Continuous monitoring and research may be required to develop techniques through the application of computer graphics and digital image processing.
