Q-Switch Driver which is enable to perform Q-Switch of Q-Switched Nd:YAG Laser device use Fly-Back Converter Topology. Fly-Back Converter Transformer for high Voltage generation over 4KV is becoming a problem of the isolation in Transformer primary and secondary. In this Study, we confirmed high Voltage over 4KV designed by Boost Converter Topology, and measured characteristics between Fly-back Converter and Boost Converter in Q-Switched Nd:YAG Laser device. In addition, we improved isolation problem of Transformer primary and secondary. New Q-Switch Driver (Boost Converter) was confirmed potential for more compact rather than existing Q-Switch Driver (Fly-Back Converter).

In this study, we proposed a water rocket CULV-1 (Chosun University Launch Vehicle-1). Unlike a conventional water rocket, CULV-1 can perform the booster rocket, fairing, and payload separation like an actual launch vehicle and also the imaging data acquisition. The conceptual and critical design of the proposed CULV-1 have been performed considering the operation characteristics. The verification tests have been performed from subsystem to system level in accordance with the established test specifications and verification procedures. Through the final launch test of the flight model, we have verified the design effectiveness of the proposed separation mechanisms for water rocket applications and the mission requirements of the CULV-1 also have been complied.

This paper deals with the experimental study for the application effect of far-infrared radiation heater as vehicle cabin heating. Radiation heater can provide quick heating effect direct on the body with low energy consumption. It has no noise, no vibration and no discomfort of heated air when breathing. In this this paper, carbon thread face heating radiation heater that heats about 100℃ is used as a device for the vehicle application. The vehicle wind tunnel test was performed to study the effect on the thermal comfort and heating energy consumption. And also by this test, best radiation heater’s position and proper heating temperature was studied. As a result of vehicle test, thermal comfort level reaching time is reduced by 30~40%, heating energy consumption is reduced by 29~40% at -10, 5℃ ambient temperature.

The aim of this paper is to investigate the application of low cost CCS(Climate Control Seat) using a HVAC(Heating, Ventilation and Air-Conditioning) system. CCSs is being vigorously purposed because requests for passenger`s thermal comfort are increasing. However current CCS, which is thermoelectric device have been applied for both heating and cooling, used limited luxurious car only. HVAC type CCSs are well suited for effective delivery of conditioned air due to thermal comfort and close proximity to the occupants. Experimental results show that the HVAC type CCCs have superior cooling performance and slightly uncompetitive heating performance than that of TED type CCS. In the case of HVAC type CCSs, air flow volume was increased approximately 3.7~7.3㎥/h than TED type CCS. and surface temperature of seat was reduced about 5℃ and cool-down was similar than Base. Additionally, occupants subjective evaluation, HVAC type CCSs was reduced 8 minutes to reach the comfort rating 5 at cooling test and high comporting ration after 8 minutes at seat heating test than of TED type CCSs.

The governance model emerging in Korea is distinguished from those of UN and IBRD in the sense that it emphasizes democratization cum liberalization. This study attempts to analyze how the governance model under the Roh Moo-hyun government helped Roh to consolidate his feeble political base. Local decentralization, check on conservative media, and the promotion of civic and labor participation under the Roh government have contributed to the enlargement of his political support. It is concluded that Korean governance model based on civil participation and horizontal networks illuminates the importance of domestic political analysis for the international affairs.
