The aim of this study is to shed light on the importance of female drivers, study their characteristics and needs, and create automobile designs in accordance with the study. The power of female consumers is greatly increasing in a modern society, To the extent that women became the core consumers. Companies are now turning their attention to female consumers in order to survive the fierce competition in the saturated markets. Moreover, it is becoming imperative for companies to actively develop products and services in female perspectives to meet the diversified needs of consumers. It is forecasted that vigorous research, analysis and understanding of the unique culture of women will be increasingly important now that women are emerging as core consumers. Only the companies that makes such efforts consistently can dominate the market. The automobile industry is not an exception. The world's major automobile companies including Volvo and Ford Motor Co. are keenly focusing on automobile exterior and interior designs for women. Korean companies are also designing cars that cater to women, starting with Lanos and Juliet of Daewoo Motors in 1998, yet specific and systematic research on the subject has not been made. This study aims to emphasize the power of female users, make a research and analysis on their needs and characteristics, and suggest car interior designs that cater to them.

This study is an online survey for consumers in the metropolitan areas of Japan and Korea, which are advanced countries in Asia, and the maturity of the automobile market. The purpose of this study is to compare the results of Korea and Japan. As a result of this study, we analyzed the differences between the consumer characteristics and the optional attribute factors of low-carbon automobiles of Korea. There was a difference. It was found that the factors of low carbon car selection attribute differed with age, and that stability was more important when selecting low carbon car as income level increased. In Japan, there were no differences in the selection attribute factors of low carbon cars by gender, age and income. In addition, there is no difference in the relationship between the future purchase timings of low-carbon car types in both Korea and Japan. Implications of this study Korea has a meaningful result that Korea tends to select low-carbon automobiles with an emphasis on economic aspects and ages, and that safety tends to emphasize safety of low-carbon automobiles according to income levels. In the case of low carbon car, there was a tendency to select a low carbon car without any difference in consumer characteristics. The relationship between the expected purchase time according to the type of low carbon car and the Korean car show that the preferred car within the next 10 years among the low carbon car types is electric car and Japan prefers hybrid car.

Cyber security in the automobile sector is a key factor in the life cycle of automobiles, and cyber security evaluation standards are being strengthened worldwide. In addition, not only manufacturers who design and produce automobiles, but also due to the nature of automobiles consisting of complex components and various parts, the safety of cybersecurity can be secured only when the implementation level of the cybersecurity management system of companies participating in the entire supply chain is evaluated and managed. In this study, I analyzed the requirements of ISO/SAE 21434 and TISAX, which are representative standards for evaluating automotive cybersecurity. Through a survey conducted on domestic/overseas company security officers and related experts, suitability and feasibility were reviewed according to priorities and industries, so 6 areas and 45 evaluation criteria were derived and presented as final evaluation items. This study is meaningful as a study in that it presented a model that allows companies participating in the automotive supply chain to evaluate the current cybersecurity management level of the company by first applying ISO/SAE 21434 and TISAX overall control processes before uniformly introducing them.

Reaction injection molding (RIM) is a widely used process for producing various kinds of complex parts including automobiles, furniture, appliances, and housings. In RIM, products are made from two or more chemical components through mixing, chemical reaction, and molding [1]. Liquid reactants from two supply tanks flow at high pressure into a mix head, where they impinge at high velocity. (omitted)

Real-time traffic detection scheme based on Computer Vision is capable of efficient traffic control using automatically computed traffic information and obstacle detection in moving automobiles. Traffic information is extracted by segmenting vehicle region from road images, in traffic detection system. In this paper, we propose the advanced segmentation of vehicle from road images using multiple local region information. Because multiple local region overlapped in the same lane is processed sequentially from small, the traffic detection error can be corrected.

본 연구에서 검토한 바와 같이 컴퓨터 시뮬레이션은 실차실험과 다소의 오차는 있지만 매우 값싼 환경에서 컴퓨터장비에 거의 종속되지 않고 연구가 가능하므로 충돌실험이 고가인 관계로 여러 경우를 시도할 수 없는 경우 즉, 조인트 성격변화, 의자위치, 벨트의 신율 및 체결상태, 에어백의 장착여부 등에 대한 변화가 있을 때에 이미 확립된 모델에 입력데이타를 수정 혹은 추가함으로써 충돌시 반응을 예상할 수 있을 것으로 기대된다. 그러나, 본 연구에서는 비록 우수한 모델링이 확립되었다 할지라도, 차종이나 주변환경이 바뀔때는 다시 모델링을 해야 되는 문제가 남게 되며 이때 필요한 대상차에 대한 입력데이타가 새로이 정의되어야만 한다.

The expermental research was carried out to investigate the thermal performance of the locally manufactured radiators for 1300cc automobiles. The choice of .epsilon. value (the ratio of water tube surface area to the total heat transfer area ) resulted in remarkable difference in their performance including the Louver effect, the overrall heat tranfer coefficient and the heat dissipation capability.

This paper investigates the effects of shot peening on mechanical properties of SAE 9254, which is a spring steel used for the suspension system of automobiles. Rotary Bending Fatigue test is accomplished and the results are summarized as fellows : 1. The tensile strength and the hardness do not change so much. 2. The layer of highly residual stress is obtained by multi-stage shot peening. 3. The fatigue strength seems to be improved by residual stress. 4. The fatigue strength of un-peened and multistage shot peened material are 425 MPa and 756 MPa, respectively.

세계는 자원쟁탈전장으로 변모하는 느낌을 주고 있는 가운데 세계경제가 석유에 얼마나 크게 좌우되고 있는가는 두 차례에 걸친 석유 파동에 의하여 여실히 증명된 바 있다. 더욱이 석유가 격의 불안정한 상황하에서 자동차에 있어서 필수적인 석유에 대한 소비절약은 자동차산업에 절 대적인 과제가 될 것이며, 이밖에 안전, 고해, 소음 등에 대한 각국의 규제가 1980년대에는 더욱 가중될 것으로 보인다. 또한 고객은 정부의 볍규제와는 달리 보다 개선된 쾌적성, 자동차 및 부품에 대한 신뢰성, 내구성 및 정비성 등을 자동차업계에 강요하게 될 것이다. 따라서 자동차설 계자나 제조기술자는 이 양대요구사항들을 만족시키기 위하여 어떤 방안을 강구할 것인지 각종 문헌을 토대로 예측하여 보기로 한다.
