Wheelchair users experience difficulty when using transportation. This is because wheelchair users must use transportation means together with wheelchairs. Therefore, in this paper, we developed a wheelchair storage system for passenger's car trunk. The mechanism is designed to allow a wheelchair and the device to be housed simultaneously in the narrow space of the trunk of the sedan passenger car. Additionally, this wheelchair storage system has implemented an initial load reduction mechanism that can mechanically reduce the initial load. This wheelchair storage system verified the system's operability through the production of the prototype. This system was actually installed in the trunk of the sedan passenger's car to verify the storage process. The operation and storage process of the wheelchair storage system was been perfectly verified. This wheelchair storage system will help a lot of self-driver or an assistant (female or elderly) who use wheelchairs.

This study has developed a packaging criterion to minimize the level of discomfort which drivers using their vehicles for daily life purposes may experience due to ill designed vehicle packaging of mid-size sedan based on users' daily-life scenario. To find out optimal range of packaging dimension criterion, discomfort levels the test participants with different physical conditions suffer while performing various activities were analyzed. One hundred two test participants were carefully selected to represent entire Korean mid-size sedan owner-drivers. They were directed to test drive on the course designed to simulate mid-size sedan daily-usage scenario. At pre-designed locations, each of questions was asked to the test participants to be answered in the form of 10 point discomfort level score. By analyzing the test results, the optimal range for packaging dimensions was defined to be used as a packaging criterion.

in the late 14th century, korean confucian literati, sinjinsadaebe(新進士大夫), tried to reform korean society in the base of neo confucianism. after Joseon Founding, korean confucian literati modified a lot of confucian ceremonies in order to substitute buddhist ceremonies. at first, they titled confucian ceremonies as "gyu sik(regulation manuals)", "Eui mun(ceremonial manuals)", and "Eui je(ceremonial manuals)". but in the end, they titled confucian ceremonies as "Eui gwe(Ritual Protocol Manuals)". they also titled the reports on national occasions as "Eui gwe(Ritual Protocol Manuals)". among the confucian reforms, the most important reforms were auspicious ceremony. korean confucian literati tried to make perfect confucian auspicious ceremony. the first national achievement by confucian reformers was the five national rituals in annals of king sejong. and the second national achievement by confucian reformers was the five national rituals. the royal cart regulated in the five national rituals in annals of king sejong was cart decorated by ivory. but the royal cart regulated in the five national rituals was the sedan with cover. the reason of the change of royal cart were king sejo's political showmanship and diplomatic pretext toward ming(明) china. after the publishment of the five national rituals, the royal cart was represented by the sedan with cover.

우리나라의 자동차 산업은 최초의 고유모델 포니 이후 28년여의 기간동안 빠른 성장을 보이며 많은 고유모델 차량을 개발하였다. 초기에는 외국의 모델을 도입하는데 의존했으나, 점차로 기술개발의 독자성을 확보하게 되었다. 다양한 고유모델의 개발과 품질 향상으로 이제 자동차는 우리나라의 주요 수출품목이 되었다. 외국의 모델을 도입하던 단계에서는 우리나라에서 요구되는 특성이 차량에 반영되지는 못하였으나, 점차로 독자성을 가지는 차량을 개발해 나가는 과정 속에서 외국의 승용차와 구분되는 특성을 반영한 패키지 레이아웃에 의한 변화된 형상을 가지게 되는 것이 고유모델에서의 특징이라고 할 수 있다. 이러한 국내 개발의 세단형 승용차의 특징은 한국의 생활양식이나 특성을 반영하는 요소를 가진다. 이것으로 향후의 우리나라의 고유모델 세단형 승용차가 외국의 승용차들과는 구분되는 특징을 가지게 될 것으로 예측되며, 지금까지 발전해 온 유형의 세단형 승용차들과는 차이를 보이는 형태가 될 것으로 예측된다. 본 논문에서는 이러한 변화가 차체 형태에서 반영되어 나타나는 '포스트 세단'의 특징을 살펴보았다.

A decade has passed since the first generation of Genesis was launched in the U.S. with the plaque of Hyundai-Genesis. Genesis Motors was separated from Hyundai Motor in 2015, and has struggled to have the Genesis stand alone in the competitive U.S. luxury sedan market. The present case study aims to find challenges facing the Genesis, which Hyundai has positioned as a luxury sedan competing against conventional luxury brands such as BMW, Mercedes-Benz, and Lexus; evaluate Genesis Motors' strategic response to meet these challenges; and explore an alternative positioning strategy. Specifically, the present case study addresses barriers against the Genesis' market performance, by focusing on the obstacles rooted in the consumer perception as well as the obstacles that stem from the change in the U.S. automobile industry and the nascent network of the Genesis dealership. Genesis Motors' current strategies are evaluated, and an alternative strategy is explored that is largely based on the American consumers' perceptions of the Genesis vis-a-vis conventional luxury brands and outperforming midsize brands.

Traffic accidents in tunnel can lead to large traffic accidents due to narrow and dark road characteristics. Therefore, special care of the driver is required when is driving in a tunnel. However, accidents can happen at any time. In the event of an accident, a narrow road structure may lead to a second accident. Therefore, all facilities installed inside the tunnel should be allowed to minimize damage in the event of an accident. We confirmed the safety of the collision target through the action of the sedan, Sport Utility Vehicle (SUV) and truck when the vehicle crashed into a stairway installed on the tunnel emergency escape route, and when a concrete barrier or guard rail was installed in front of the stairway. The behavior of the vehicle has resulted in a total of three results: rollover or rollover, change of speed and angle of the vehicle after collision. The sedan and SUV were the most secure when colliding with the guardrail, but considering the truck as a whole, concrete barriers were judged to be the most suitable for minimizing damage from the first accident and reducing the risk of the second accident.

모든 차형을 간단한 이상형으로 가정하여 그들을 수치적인 값으로 비교할 수 있다면 승용차 차 체의 설계상 매우 큰 도움이 될 것이다. 실제로 새로운 모델의 차가 개발되었을 때에는 다음과 같은 이유 때문에 그 prototype body에 대한 정적 시험이 실시되고 있다. 1) 조기에 설계의 문제점이나 차체의 주결함을 발견할 수 있어 시간과 경비를 절약할 수 있다. 2) 계속적인 정적 시험을 통하여 구조적으로 만족할 만한 road car를 만들 수 있다. 3) 과설계를 방지하여 차체의 경량화에 기여하고, 최적설계의 개발을 위한 길을 제시해 준다. 차체에 대한 정적 시험은 위와 같은 이유 때문에 발전되어 왔으며, 정적 시험의 효과를 ㅊ대로 하기 위하여 그것은 순수한 공학적 원리에 기초를 두어 실제의 사용조건과 충분히 일치되는 시 험으로서 고안되었다. 차체구조는 그 사명의 다양성뿐만 아니라 제작, 개수에 상당한 노력과 시 간이 필요하기 때문에 조기에 문제점을 발견하여 결함을 제지하지 않으면 안된다. 구조체로서의 많은 필요조건 중에서 특히 중요시되는 것은 강도, 강성 및 내구성이다. 그 때문에 차체의 강도, 강성시험은 이론적인 해석(탄성학, 구조역학, 강도학 등)에 앞서 여러가지 방법이 개발되어 왔 으며, 여기에서는 그 중 가장 대표적인 방법인 비틀림시험(torsion test)과 굽힘시험(bending test) 에 관하여 Pony 4-door Sedan 차체의 시험 결과를 토대로 하여 기술하고자 한다.

The fatality of pedestrian accounts for about 21.2% of all fatality at 2007 year in Korea. In car to pedestrian accident it is very important to inspect the throw distance of pedestrian after collision for exact reconstructing of the accident. The variables that influence on the throw distance of pedestrian can be classified into the factors of vehicle and pedestrian, and road condition. It was simulated by PC-CRASH, a kinetic analysis program for a traffic accident in sedan type vehicle and SPSS program was used for regression analysis. From the results, the throw distance of pedestrian increased with the increasing of vehicle velocity, and decreased with the increasing of impact offset. Also it decreased with the increasing of velocity of pedestrian at accident, and throw distance at the road condition of wet was longer than that at dry condition. Finally, the regression model of sedan type vehicle on the throw distance of pedestrian was as follows; $$dist_i=2.39-0.11offset_i+0.59speed_i-545height_i-0.25walk_i+2.78wet_i+{\epsilon}_i$$.

As one of the alternative solution for energy and environmental issues such as climate change, energy security, oil price, etc., hydrogen energy has been getting so much attentions these days. This paper analyzed the $CO_2$ emission, costs, and energy consumptions when the hydrogen energy was introduced to transportation, specifically in Sedan sector using the energy system model, MARKAL. As results, 21.5% of $CO_2$ emission in 2040 could be reduced and additional 76 billion dollars will be needed in the high energy price scenario. The amount of energy saving mainly due to the replacement of existing car to hydrogen vehicle was 16% of the final energy consumption in 2040.
