기존의 배터리 관리시스템에서 셀전압 측정을 위하여 PhotoMOS relay를 사용하는데, 대용량 전지 팩은 다수의 PhotoMOS relay를 필요로 하며, 가격 또한 고가이기 때문에 전체적인 시스템의 가격 상승을 초래한다. 이러한 문제점을 해결하기 위하여 본 논문에서는 저항을 이용한 전압분배 회로를 통해 고전압(600V)의 battery module 전체 전압을 package 별로 측정하는 PVM(Package Voltage Monitor) 개념을 새롭게 도입한 것으로, 기존의 방식보다 동작속도 개선 및 저전력 동작, 원가절감의 효과가 있는 시스템 구성을 소개한다. PVM 방식을 이용한 배터리관리시스템은 하이브리드 자동차뿐만 아니라, DMB, E-Scooter E-Bike 동 배터리 팩이 사용되는 모든 시스템에 적용이 가능하며, 배터리 관리시스템의 개선에 기여할 것으로 기대된다.

The purpose of this study was to examine the relationship among university golf class participant motivation, class involvement, class satisfaction, and exercise adherence. The subjects were selected by university students who had experience about golf class at five different university in Seoul by using convenience sampling method. A total of 370 samples were distributed and 365 usable data were finally conducted. Frequency analysis, and reliability analysis were tested by using SPSS 14.0, and confirmatory factor analysis, corelation analysis, and SEM by using AMOS 7.0. The results of this study were as follows. First, internal motivation had effect on class involvement, class satisfaction, and exercises adherence intention. Second, no-motivation had not effect on class involvement, class satisfaction, and exercise adherence intention. Third, external motivation had effect on class involvement, class satisfaction, and exercise adherence intention. Fourth, class involvement had effect on class satisfaction. Fifth, class involvement and class satisfaction had effect on exercise adherence intention.purpose

The study was to examine the Relationship among ethical leadership of university sports team leader, organizational trust, leader trust, loyalty. For this purpose, data were drawn for 249 university athletes in Seoul and Gyeonggi-do. As the statistical method for this research, the SPSS 15.0 version and AMOS 7.0 version statistical program were used frequency analysis, confirmatory factor analysis, reliability analysis, correlation relative analysis and structure equation model analysis in these date. Result of the analysis are as follows. First, ethical leadership of university sports team leader was found to have significant influence on organizational trust. Second, ethical leadership of university sports team leader was found to have significant influence on leader trust, Third, organizational trust was found to have significant influence on loyalty, Fourth, leader trust was found to have significant influence on loyalty

The study was to examine the structural Relationship among golf Course employees’s the job embeddedness, job burnout, and remaining in organization. For this purpose, data were drawn from 458 employees working at ten membership golf Courses in Gangwondo. As the statistical method for this research, the SPSS 17.0 version and AMOS 7.0 version statistical program were used frequency analysis, confirmatory factor analysis, reliability analysis, correlation relative analysis and structure equation model analysis in these date. Result of the analysis are as follows. First, golf course employees’s ob embeddedness was found to have significant influence on job burnout. Second, golf course employees’s job embeddendness was found to have significant influence on remaining in organization. Third, golf course employees’s job burnout was found to have significant influence on remaining in organization.

The field of the large volume heat exchanger for wasted heat recovery ventilation system is being expanded enormously seeing as the fact that the quantity of reducing energies are huge due to the large volume heat exchanger for wasted heat recovery system at large buildings and factories, which consume large amount of energies while it has been arising huge amount of losses in Korea because of the lack of technology. To develop large volume waste heat recovery heat exchanger, rotor type heat exchanger was simulated for the surface corrugation. Based on the simulation results produced 30,000 ㎥./h grade waste heat recovery, heat exchanger was performed for the actual experiment. In addition, performance tests exceed the capacity of a large waste heat recovery heat exchanger performance test methods proposed.

It has been investigated for the temperature profile in a planar evaporator of micro-cooler subject to a uniform heat flux prior to tole initiation of boiling. The results of the analysis allow for the determination of applied power levels fur which nucleation is likely to occur only within the vapor grooves of the evaporator while maintaining subcooling in the liquid core, thereby increasing the likelihood of a successful startup. Also, limits are fecund for which additional increases in the applied heat flux do not increase the temperature difference between the vapor grooves and the wick-liquid core interface. This analysis is appropriate for the microscale evaporators of micro-cooler during a fully-flooded startup as well as starter pump designs and micro-CPLs(capillary pumped loops). The results are useful in the initial basic design of microscale heat transfer devices.
