  • 자동차 man-machine system의 interface를 이루는 Display panel, Center fascia, Steering wheel, Rear view, Gear, Power window switch, Seat 등과 이들의 Layout은 운전자의 안전뿐만 아니라, 안락감과 밀접한 부분으로 알려져 있다. 따라서 이러한 설계요소들의 Man-machine interface의 최적화를 위한 인간공학적 접근이 필요하다. 운전자의 안락감은 Seat, Pedal, Steering wheel 등 뿐만 아니라 각종 조작장치(Audio, Switch, Gear,…)도 함께 연구되어야 하다. 따라서, 본 연구에서는 실험용 Seating buck을 제작하여 실내 조작장치 중 오디오를 대상으로 터치스크린과 Rapid Prototype을 이용해 사용성 평가에 대한 적합성을 검증하고자 하였다. Rapid Prototyping 기법은 디자인단계에서 제품 사용상의 문제점을 발견 개선할 수 있다는 장점이 있다. 그러나, 본 연구 결과에서 3가지 항목 중 1가지만이 실제 Audio와 Prototype에서 차이가 없었다. 따라서, Prototype의 접촉감과 입체감의 개선, 실사용과 동일한 환경의 제시, 소리와 같은 정확한 반응의 제시, Glare의 제거, 사용자 분석에 따른 실험 데이터의 축적 등을 고려하여 Rapid Prototyping을 구현하여야 할 것이다.

  • In 2019, SUV sales surpassed sedans in the domestic sales market with phenomenal domestic sales. The strength of SUVs around the world is expected to continue in the future. South Korea's K-company aggressively launched small SUVs in the SUV market. Its simple lineup is recognized as a brand image, not as a SUV. It is time to evaluate this. Therefore, it influences the purchasing decisions of potential customers and buyers of small SUVs through the evaluation of design images of small SUVs in Korea. Rather than the functional properties of the SUV model, it is purchased by emotional characteristics, brand symbolism, and image. Subconsciousness of the purchasing psychology of the end consumer was used by metaphor extraction techniques. Customers wanted to study the evaluation of small SUV design images that fit their needs. We wanted to see if consumers who intend to purchase or purchase small SUVs in Korea had a connection with the image of design of small SUVs in Korea. The conclusion of the study was extracted through ZMET, a metaphor extraction technique, with the latent consciousness of the primary ambiguous message from the consumer's feeling and representation of the image. Therefore, based on the results of this study, we hope that the images presented in SUVs in the future will be used as a design guide in the development of small SUVs to influence customer thinking and behavior.

  • As the requirement of the in vehicle infotainment service increases, the role of the in vehicle display is also expected to rise. Particularly, center information display(CID) is expected to be actively utilized, and since the size and position of the display is anticipated to change, it is necessary to research based on the users' perspective. However, there are limited research studies that investigated the user's consciousness on the size and position of autonomous vehicle display. Herein, the purpose of this study is to identify and present the preference of the center information display's size and position on each levels of driving automation. For this, an experiment on the driving simulator was conducted using the think-aloud method. As a result, it was found that the horizontal display(12.5inch) on the top position was the most preferred in the second level of the driving automation. On level three, the participants significantly preferred the vertical display(17inches) compared to the second level. This study is significant since it conducted an empirical study which examines the user' preference of CID using a driving simulator for the autonomous vehicle.

  • The auditory information is used for urgent notification or warning in vehicle because it is not restricted by the direction compared to the visual. However, since the hearing impaired drivers cannot recognize sound signal, various methods of visualizing the auditory information have been attempted to replace it. When visualizing auditory information, only important information should be selected and provided to prevent cognitive overload concentrated on the vision. For this purpose, analysis of the type of auditory information in vehicle should be given in advance. In this study, the types of auditory information in vehicle were analyzed based on the user experience of hearing impaired drivers. Through the observation of the driving behavior of hearing impaired drivers, 33 auditory informations experienced in vehicle were collected. The collected auditory informations were classified into 12 groups through open card sorting by an expert group, and the types of auditory information in vehicle consisting of four levels were presented through a relative comparison of importance between groups. The presented type of auditory information in vehicle can be used as a guideline for selecting important information when the auditory information is converted into visual or tactile. This study is meaningful in that the user experience analysis was conducted by observing actual driving in daily life of hearing impaired drivers.

  • In the hope of realizing carbon neutrality, Korea has established the goal of expanding the supply of hydrogen electric vehicles through a roadmap to revitalize the hydrogen economy. A prerequisite for successful supply expansion is securing the safety of hydrogen electric vehicles. Certain parts, such as the hydrogen transport pipe and tank, in hydrogen electric vehicles are exposed to high-pressure hydrogen gas over long periods of time, so the hydrogen enters the grain boundary of material, resulting in a degradation of the parts referred to as hydrogen embrittlement. In addition, since the safety of parts utilizing hydrogen varies depending on the type of material used and its environmental characteristics, the necessity for the enactment of a hydrogen embrittlement regulation has emerged and is still being discussed as a Global Technical Regulation (GTR). In this paper, we analyze a hydrogen compatibility material evaluation method discussed in GTR and present a direction for the development of Korean-type hydrogen compatibility material evaluation methods.

  • 금(Au) 및 금의 합금도금은 주로 극히 얇고 색상만 나타내는 정도의 장식용으로 많이 사용되고 있으나 단순한 장식품뿐만 아니고 스마트폰, 정보통신 서버, 전자기기, 자동차, 전지용에도 널리 사용되고 있다. 특히 로켓공업이나 인공위성의 와곽부, 엔진에는 필수적이다. 현재 미국의 금도금액 85%는 전자부품과 인공위성(NASA) 등의 공업용에 사용되고 있다. 금도금의 이용가치는 주로 내식성이며 전기저항이 작고 열전도성이 뛰어나 전기접전부에 필수적으로 사용해야만 한다. 또한 2007년 유럽의 RoHS규정에 의해 피부에 접촉하는 팔찌, 귀걸이, 목걸이, 반지 등의 디자인 액세서리 제품에 있어서도 종래의 6가 크롬이나, 납, 수은, 카드뮴 사용이 금지되었다. 종래의 산성, 알칼리성, 중성 금도금에서는 주로 시안(Cyan) 기반의 전처리 탈지액이 사용되고 있어 작업환경에도 유해하며 생산성 감소로 이어지고 있다. 이에 전해 금도금 전처리 탈지공정을 개선함으로써 품질불량 20%감소와 함께 작업환경 개선으로 생산성 30%향상을 기대할 수 있다.
