Fuel cell technology is the most representative area of alternative energy field on vehicle industry according to the limitation of petroleum resources. In recent years, the technology of fuel cell vehicles has made rapid progress, Hyundai Motor Company (HMC) reached to mass production of the Tucson ix hydrogen fuel cell vehicles first in the world. In addition, HMC is accelerating the development of hydrogen fuel cell buses, which have a number of advantages for hydrogen infrastructure and mass transport personnel. In this study, we examined potential of the commercialization through the demonstration of hydrogen fuel cell buses. As a result, we identified that the mass-production possibility of FCB has high potential and HMC's technology will lead to fuel cell bus industry.

In the past, transmission error(T.E.) has been identified as one of the main sources of gear whine noise, which cause serious passengers irritation at high frequency. In this study, to identify the correlation of the T.E. and gear whine noise, a T.E. measuring system was developed. By comparing the T.E. and gear whine noise level, T.E. target value which can represent the gear noise was proposed. The conclusions are followed: (I) It is possible to measure T.E. of the gear pairs (II) Similar trends are observed between T.E. and gear whine noise. (III) By observing the T.E. pattern, presence of sideband noise can be predicted. (IV) Proposed T.E. target value can be adopted to the gear manufacturing for gear noise quality management.

Polymer Electrolyte Membrane Fuel Cell (PEMFC) stack power output is needed to be approximately 100 kW to meet the requirements of automotive applications. In order to secure the electric safety for drivers, passengers and mechanics, it is very important to understand phenomena of an electric insulation in a fuel cell vehicle. In this study, we studied the electric insulation properties and the insulation resistance of stack, system and vehicle in the field of fuel cell was estimated at the applied voltage of 500 V, respectively. Also we discussed the insulation factors such as the conductivity of coolant, the element of vehicle design and the intrinsic resistance of the vehicle components.

Purpose: This study compares quality crisis and management at Hyundai Motor in the late 1990s and Toyota Motor in the late 2000s. We can expect to induce more meaningful policy implications in quality management from this in-depth comparative case study. Methods: This study compares two cases at Hyundai and Toyota Motor how to overcome quality crisis based on the OESP (Organization-Environments-Strategy- Performance) model. Results: Hyundai Motor shows centralized approach based on the asymmetric organizational culture and the entrepreneurial leadership but Toyota shows decentralized, systematic approach based on the steady state leadership and symmetric organizational culture. The CEO's leadership have proved to be one of the important factors at both companies. Conclusion: The effective quality management in global contexts has become more and more difficult for the 'complexity explosions' in automobile industry. As a consequence, the future competitive edge of world automobile industry will come from the effective quality management of products in global contexts.

Fuel cell vehicles are equipped with Pressure Relief Devices(PRDs) installed in pressure tank cylinder to prevent the explosion of the tank during a fire. PRDs are safety devices that perceive a fire and release gas in the pressure tank cylinder before it is exploded. But if the PRD does not actuate, because either the PRD fails or can't be surrounded by the flame of a fire, the tank will rupture and produce a blast wave and hydrogen fire ball. In this paper, we observed the fire behavior of actual fuel cell vehicle, comparing with that of gasoline vehicle.

Proper discharge of nitrogen gas and water condensate is required in a conventional fuel cell system for performance, stability and durability of fuel cell stacks. Present study covers the development of integrated unit and its functioning logic for simultaneous nitrogen gas purge and water condensate drainage in a fuel cell vehicle system. Configuration of condensate drainage pipe, purge valve and level sensor is considered and optimized in physical integration. As a key factor, discharge time is considered and optimized based on the test result of constant-current operation with various operating temperature in logic development. Consequently, derived optimal values are applied and verified in actual vehicle drive mode test. Increase of system design flexibility, weight reduction and cost reduction are anticipated with this study. Additional study for physical and logical improvement is currently being implemented.

In this paper, light-weight system of linear induction motor(LIM) for light railway train is presented, and is compared with former type of LIM. For the light-weight system without modification of motor size the material of primary core(silicon steel) is changed with iron-cobalt alloy and the material of primary winding(copper) is changed with aluminium. The characteristics of LIM are analyzed. Specially, the air gap magnetic flux density distribution due to end effect is showed with motor velocity, we will present papers continuously through designing and testing a trial product.

본 연구는 언어 네트워크 분석 기법을 이용하여 현대자동차의 문화마케팅 유형과 변화를 분석하고 국내 문화마케팅의 발전 양상을 제시하고자 하였다. 기존 연구는 기업 문화마케팅의 개념 규정과 유형화, 문화마케팅의 영향 및 성과 등을 살펴보았지만, 시간의 흐름에 따른 기업 문화마케팅의 변화는 주목하지 않았다. 이에, 본고는 다양한 형태의 문화마케팅을 시행해온 현대자동차를 대상으로, 현대자동차의 문화마케팅이 보도된 2001년부터 2018년까지를 시간적 범주로 설정하고 국내 일간지 기사 2,315건을 분석하였다. 18년의 시간을 4개 시기로 분류하고, 시기마다 빈출단어를 추출하여 한국어 언어 분석 프로그램 텍스톰(Textom)과 언어 네트워크 분석 프로그램 유씨넷(UCINET)으로 분석하였다. 연구 결과, 현대자동차는 문화마케팅을 판매와 영업 성과를 향상하기 위한 수단으로 활용함과 동시에 기업과 브랜드 정체성을 차별화하기 위한 전략으로 발전시키고 있었다. 2000년대 초반에는 '고객', '위대한 회화의 시대: 렘브란트와 17세기 네덜란드 회화전', '공연'이 빈도수가 높은 단어로 추출되었다. 현대자동차가 공연 중심의 문화 행사를 고객 대상으로 개최하여, 특정 소비자 그룹에 혜택을 제공하는 방식으로 시작하였다. 2000년대 후반에 상위 노출된 단어는 '예술의 전당', '서울시립교향악단'으로, 인지도 높은 문화예술기관의 주요 문화 행사에 후원하였다. 2010년대 초반에는 기존고객 중심에서 잠재 고객으로 대상을 넓히고, 문화마케팅을 아우르는 브랜드와 공간('브릴리언트'와 '현대아트홀')을 선보였다. 2010년대 중후반에는 노출 빈도가 높은 '브랜드'와 '글로벌'에서 보여주듯, 문화마케팅의 초점이 고객에서 브랜드 구축으로, 국내에서 글로벌로 확장되고 있다.
