  • Heat pumps transfer heat by circulating a substance called a refrigerant through a cycle of evaporation and condensation. But Heat pumps system by only using heat-source is not efficient. Because the mean temperature of North Korean winter season is low, economy of air heat-source heat pump descend. This paper is practiced the simulation on evaluation criteria for Heat pump heating and cooling systems to Rolling Stock. Efficiency of the heat pump in order improving from certainly the development of the technique will be able to prevent a freezing actual condition must proceed. As a result, Below $-10^{\circ}C$ used heating and cooling systems of heat pump format even in cold winter season and is serviceable confirmed with heat source supply circle of the Rolling Stock.

  • This study was carried out to research the size satisfaction and the actual conditions of house caddie uniforms. Survey participants consisted of 310 caddies at 6 membership golf clubs. In order to perform this study 45 questionnaires were used, which consisted of questions pertaining to size satisfaction and sewing, laundry management, and inconvenience and, most importantly performance. Frequency analysis was implemented using SPSS 10.0. The results of this study could be summarized as followed; The highest dissatisfaction factors in the presently worn uniforms were sleeve length and pants hem width. The highest dissatisfaction factors in the sewing satisfaction were pocket and armpit area. Activity is the most important consideration in the choice of a uniform. These results will be applied to develop a comfortable uniform design.

  • We pursue pleasure through game but also possibly get positive effects. The serious game is a game that achieves a certain goal by using the positive effects of games. This paper describes the serious game and rehabilitation. Also, it describes the types of medical serious games and actual development condition of serious games for rehabilitation, and suggest ways to inspire utilization of the serious games for rehabilitation.

  • Finite element analysis (FEA) and experimental studies on an elastic bending method have been performed in order to control the angular distortion at the fillet weldment for curved panel. Process parameters for the elastic bending method such as clamping span and release time were analyzed with reference to welding condition and geometric effect of the curved panel, which can minimize or prevent the angular distortion by producing a proper skin stress to the fillet weldment. The amounts of the angular distortion decrease almost in a linear manner with an increase in the skin stress. The skin stress required for non-angular distortion at the fillet weldment is strongly dependent on the plate thickness, not the heat intensity applied. The clamping span for obtaining uniform skin stress was defined as functions of the plate thickness and length of the free edge. Clamp should be removed after the fillet weldment is cooled down to room temperature for non-angular distortion. Effectiveness of the elastic bending method established was verified by its application to an actual curved panel.

  • The disabled peoples increase in number by disasters from the industrialization and urbanization. The physically handicapped people experience many difficulties in using the facilities in the public buildings. So, this survey proposed the necessary conditions for the handicapped peoples to use without any trouble in public buildings. The objects of investigation were public buildings, village offices, a public library, synthesis hospitals banks, an express bus station, a wedding building, a railroad station etc.. Conclusions were as follow \circled1 The most of buildings were established access road in regulations but parking area was established inappropriately in regulations \circled2 The most of convenience facilities were concentrated on first floor but were established barely in more than second floor. \circled3 The most of convenient facilities were established in appropriately in regulations. \circled4 The other convenient facilities(reception desk, ticket agency, work desk etc.) were not established nearly in the buildings of investigation.

  • The objective of this study is to evaluate properly reliability of underground distribution system taking into account domestic circumstance. Interruption time and number of interruption customer by distribution system based on actual condition in domestic utility are considered as important index to estimate reliability of underground distribution system. This paper presents evaluation results regarding the reliability of an underground distribution system using a model system as new urban area, evaluation results which is established whether automatic system is introduced or not are shown in detail.

  • Hypoid gears are widely used in rear drive and 4WD vehicle axles. Investigation of their sensitivity to deflections is one of the most important aspects of their design and optimization procedures. The deflection test is performed in the actual gear mounting using completely processed gear. This test should cover the full operating range of gear loads from no load to peak load. Under peak load the contact pattern should extend to the tooth boundaries without showing a concentration of the contact pattern at any point on the tooth surface. Transmission error is tested on an axle assembly triaxial real car load condition.

  • The important issue of equipment installed in maritime weapon system is shock survivability against underwater explosion(UNDEX). If the shock survivability of equipment should not be guaranteed, the successful mission also could not be achieved. For that reason, the shock-resistance of each equipment under UNDEX environment should be demonstrated before deployment at combat field. However, the actual UNDEX test on the ocean is too expensive to conduct. Also, it has diverse dangerous factors. The main characteristic of UNDEX is a dual-pulse shock. The vertical shock test machine able to simulate dual pulse shock signal on the ground will be introduced in this paper. The dual-pulse shock signal presented in certain shock standard was achieved with this shock-test machine on the ground. The analytical procedure to set a test condition was verified by comparing simulation result with experiment result.

  • This study describes to analyze variation of carbon dioxide gas concentration by experimental and theoretical method according to the using patterns of ventilation system in a model classroom. Concentration of $CO_2$ gas varied by the occupancy and the ventilation systems are operating or not. More than 850 CMH ventilation system can maintain $CO_2$ gas concentration lower than 1,000 ppm along the class time and can be adopted the government guideline. Theoretical modeling of the concentration was performed at well-mixed ideal condition. Delays of concentration decay were shown at each case compared to actual.
