KAERI has developed a KALIMER-600 which is a pool-type sodium-cooled fast reactor with a 600MWe electric generation capacity. For a SFR development, one of the main topics is an enhancement of the reactor system safety. Therefore, we have a long-term plan to design the large sodium experimental facility to evaluate the reactor safety and component performance. In order to extrapolate a thermal hydraulic phenomena in a large sodium reactor, the thermal hydraulics phenomena is under investigation in a 1/$10^{th}$ water-simulant facility for the KALIMER-600. In this paper, we shortly described the experimental facility setup and the measurement of the isothermal global flow behavior. For the flow field measurement, the PIV method was used in a transparent Plexiglas reactor vessel model at around $20^{\circ}C$ water condition.

The supurfluid shock tube facility has been developed as a versatile tool for experimental research of low-temperature thermo-fluid dynamic phenomena The shock tube is designed to operate with the He II filled test section which is immersed in superfluid helium. The thermo-dynamic phenomena occurred in this facility are measured using pressure transducers, superconductive temperature sensor and visualization method. In this paper, the design and performance of the superfluid shock tube facility and the superconductive temperature sensor is presented.

The goal of this survey is to propose planning and design informations for the public open spaces in apartment housing, through the observation and analysis of the current situations. For this, the planning information of housing suppliers about public open spaces and the spatial utilization of users were compared and by analyzing facility utilization and resident\`s recognition. This study is also intended to guide the future directions of the research for the improvement of public open spaces. The research follows three phases; \circled1 To understand the conditions of public open spaces in apartment housing sites through survey and analysis of catalogues and references. \circled2 To study on facility utilization and resident's recognition by observation and analysis. \circled3 To propose planning guidelines for the improvement of public open space by recognition differences of facilities.

The method suggested in this thesis is the safe and economic method when testing rocket engine because ground test facility copies high altitude. We have decided to use the schematic of testing facility based on already known design method and test result, and we have decided the test condition for ground firing test of solid fuel. In addition the pressure of nozzle exit area is 0.1bar, we have designed the testing facility structure to test in this condition. Moreover, we have designed to reduce the accident probability.

To increase the short-circuit testing capacity of distribution transformers, testing facility has been installed for KEPCO in Vi-wang. The power supply of testing facility is directly supplied from the network substation located closely. Testing can be performed up to 300 kVA for single-phase transformers, 500 kVA for three-phase transformers. Operating with this facility, the distribution company is able to maintain the reliable supply of electricity. Also the critical quality of transformers from manufacturers can be verified by short-circuit testing. This paper describes the design concept and specification of newly developed equipment and the procedure of short-circuit test.

In order to design mutual communication between a distributed control system and a function test facility, we used the Inter-Process Communication(IPC) in two systems and Transmission Control Protocol/Internet Protocol(TCP/IP) protocol. The data from the function test facility are put in the shared memory using an IPC, which is then accessed by the distributed control system through an Application Program Interface(API). The server in the function test facility includes two processes(one for sending and one for receiving), which are generated by the fork function from the client signal. The client in the distributed control system includes two separate programs(one for receiving and one for sending).

In order to study the performance characteristics of the thrust vector nozzle, the test facility and instrumentation system were designed. In this system, axial thrust, moment, exhaust gas velocity and pressure will be measured by using the scale down experimental model devices. The test facility are composed of high pressure air storage system, flow measuring and control system, test nozzle and thrust measurement system.

Hypersonic engine test facility with ejector system was tested. Ejector system was designed by revised EJSIMP code. The performance of the ejector system was predicted by numerical analysis. As a result, ejector system satisfied the facility design requirement. Based on the pressure level, the facility was successfully started at Mach 3.5 and 20km altitude condition.

For prevention of the school violence, many researchers have been conducted the studies based on crime prevention through environment design(CPTED) in the architecture planning phase. However, besides of architecture planning, the study considering the aspect of the facility management is needed during life cycle of educational facilities. In this study, the objective is to propose the effective school facility management for violence prevention based on CPTED method during life cycle of the facilities.
