The purpose of this article was to determine how the current auto mechanic's coverall restricts movements, to develop prototype coverall, and finally, to improve working efficiency. To investigate the problem and complaint of current coveralls, 35 mechanics were interviewed. Video captured method was used to analyze the representative movement. Based on the previous investigation, the prototype coverall was developed. Pleats and band were inserted on each side of the back, under the armhole, and the back waist area for flexibility. To analyze the mobility of current and prototype coveralls objectively, range-of-motion of selected movements was measured by Leighton flexometer and goniometer. Also, wearer acceptability scale was tested to investigate subjective preference of current and prototype coveralls. As subjects, 10 auto mechanics were participated. Order of testing was randomized. ANOBA and LSD were used for statistical analysis. As a results, prototype coverall was significantly different from current coverall at all test movements. Also, prototype coverall was significantly different from current coverall at 13 scales among 23 subjective scales. The results identified that prototype coverall design improved auto mechanic's body movement and subjective acceptability.

For the purpose of evaluation the damage repairability of a Frame Type Passenger vehicle which experienced a Low Speed 40% Offset front and rear Crash Test. tests were made according to the RCAR testing procedures. Test results concluded ; (1) The deceleration at C.G(center of gravity) off 6.9∼11.39 was similar to that for the vehicle. The airbag system was found to affect neither the passenger's safety nor the savings of the repairing costs. (2) In order to improve the repairability of the Frame Type Passenger vehicle after collision should be a higher crash performance of the bumper on the RCAR standards.

The Korea's safety standards for vehicle have been strengthened to reduce casualties from traffic accidents since 1962. The standards have a rather complicated structure. The safety standards are composed of the main text and asterisks, and the safety standard implementation rules are composed of the main text, asterisks and appendices, and items of the same name are stipulated in other chapters within the safety standards. This study is to suggest improvement measures such as simplifying the structure of these safety standards and integrating safety standard items with the same name. Through this, users' understanding of the standards will be improved, and it is expected that the system will be more efficient such as securing safety quickly through harmonization with international standards following the development of rapidly changing new technologies such as automated vehicles.

The Korea's automobile safety standards consist of standards for automobiles, automated vehicles, two-wheeled vehicles and auto parts, and there are 157 articles. In connection with the safety standards, the implementation rules stipulated for detailed test methods and procedures are composed of the main body, asterisks and annexes, and have a rather complicated structure. In addition, the test items in the asterisk are specified with the same or similar name as the test items in other asterisks. In this study, the structure of these implementation rules is simplified and the same test items are integrated. This is expected to increase the user's understanding of laws and regulations and efficiency.

Recently 4th Industrial Revolution era has come up and autonomous vehicle gets a huge attention for its commercialization as well as development. To this end, many countries such as US, UK, Germany are looking into laws and policies related to autonomous vehicle making a new law system, laws, policies or at least modifying the existing ones. Korea is also facing commercialization and development of autonomous vehicle yet it's law system, laws and policies are far beyond comparing to those of advanced countries. This paper details current law system comparison of several countries providing differences and characteristics for the purpose of success of auto drive vehicle industry. On top of that we suggest a new law system, laws and policies and then provide directions as steps for mature implementation. In addition, we discuss how the new laws and policies can bring out successful commercialization as well as industrial success of autonomous vehicle at the points of consumers, vehicle makers, insurance companies, and government.

In this paper, we propose an efficient car management system based on object-oriented modeling using car number recognition and smart phone. The proposed system perceives car number of repair vehicle after recognizing the licence plate using an IP camera in real time. And then, existing repair history information of the recognized car is be displayed in DID. In addition, maintenance process is shooting video while auto maintenance mechanic repairs car through IP-camera. That will be provide customer car identification and repairs history management function by sending key frames extracted from recorded video automatically. We provide user graphic interface based on web and mobile for your convenience. The module design of the proposed system apply software design modeling based on granular object-oriented considering reuse and extensibility after implementation. Car repairs center and maintenance companies can improve business efficiency, as well as the requested vehicle repair can increase customer confidence.

Systematic safety research by Korea Government has been made to enhance the safety of CNG (compressed natural gas) vehicles since the burst of compressed cylinder of an urban bus in August 9, 2010. This article summarizes some major activities to ensure the safety of CNG vehicles, which covers review of regulation, safety management system including standard of inspection and certification, and training program of inspectors and car mechanics. Specifically, the followings were reviewed; type of CNG cylinder, location of CNG cylinder, material and type of fuel line and vent line, modification of pipeline connection, installation of gas detector, installation of emergency shutdown valve, installation of protecting cover for cylinder, obligations for CNG vehicle filling station. improving periodical inspection, routine test on gas vehicles, training program for engaged in gas vehicles, and designation of safety manager for CNG bus company. This paper suggests how to improve safety of CNG vehicles as a result of review of above mentioned check items.

내연기관은 자동차용 기관에 의하여 일반대중과 접촉하게 되었으며, 특히 20세기 중반에 이르러 자동차라는 기계가 일반가정에서 사용되는 가구로 탈피하는 과정에서 그 중요장치의 하나인 자동차용 기관도 전문가가 취급하는 기계로부터 일반인이 취급하는 가구로의 탈피를 요구함에 따라 크게 발전해 온 것이 사실이다. 종래, 내연기관의 설계에 있어서 그 출력과 연료소비를 가장 중요한 성능평가의 요소로 삼아왔지만, 가구로서의 자동차의 최적화를 위해서는 더욱 중요한 많은 성능평가의 요소가 있다는 것을 인식할 필요가 있다고 생각한다. 실은 최적화에 필요한 많은 요소의 균형을 어떻게 할 것인가 하는 것이 자동차용 기관의 설계에 있어서 가장 중요한 일이라 생각되며, 자동차용 기관을 계획할 때의 목표는 다음과 같은 3가지로 생각된다. (1) 고성능일 것 (2) 우수한 기능을 가질 것 (3) 공해가 없을 것 (1)의 고성능을 추구하는데 있어서는 비출력, 연료소비율 및 양호한 응답성이 중요한 요소로 된다. 이중 응답성의 문제는 연료공급기구나 조속기 등의 기능적인 요소와 깊은 관련이 있다. 그리고 내구성, 신뢰성, 정비점검의 무용성이라는 것이 (2)의 우수한 기능을 보장하기 위한 가장 중요한 배경으로 된다. 또한 진동이나 소음이 없고 정숙할 것이 (3)의 무공해성의 목표와도 관 련되는 중요한 요소이다. 배출가스의 무공해화가 자동차에 의한 공해방지의 입장으로부터 중요한 요소가 되는 것은 주지의 사실이다. 그리고 이 배출가스의 청정화의 문제는 성능향상을 위한 비출력증대의 방향에 대한 방해가 되는 문제이다. 이상 기술한 바와 같은 설계단계에 있어서의 계획목표를 3가지로 설정하고, 이 3가지 목표에 관련되는 요소의 균형을 어떻게 위해야 할 것인가 하는 점에 초점을 맞추어 되도록 쉽게 기술하고자 하였으나, 미비한 점이 많았을 것으로 생각하여, 다만 이 분야에 종사하는 기술자 여러분에게 약간의 도움이라도 되었으면 하는 것이 소망이다.

In terms of service quality evaluation, consumers think that the product they have bought is of good quality only when they are provided with satisfactory service. The purpose of this study was to examine the influence of service quality on customer satisfaction, repurchase intention and word-of-mouth intention in the automobile service industry and the possible mediating effects of Parameters by obtaining empirical data. A survey was conducted to gather data, and the collected data were analyzed by a statistical package SPSS. As a result, it's ascertained that the quality of service was one of integral factors for customer behavioral intention, and Parameters turned out to have strong mediating effects on the quality of service and customer behavioral intention as well.
