Previous research has mainly investigated the characteristics of expertise by using typical and routine tasks. This research to overcome these limitations included non-routine task situations and observed expert and novice pilots' situation awareness (SA) performance in routine and non-routine situations. Additionally, whether the ability to aware or perceive the environmental information in limited time varies with the level of expertise was tested. To this end, $2^*2^*2$ mixed factorial design was employed, including expertise (novice/expert) as a between-subjects variable and normality of fight situation (routine/non-routine) and stimulus display time (long/short) as within-subjects variables. As results, there was no performance difference in routine situations between experts and novices, while experts significantly outperformed novices in non-routine situations. When the display time became shorter, overall SA accuracy was decreased for both experts and novices, whereas experts' performance remained significantly higher than novices in short and long conditions. When we examined the interaction between the normality of fight situation and stimulus display time, there was no difference between experts and novices in routine situations for both short and long conditions. In non-routine situations, however, experts' SA accuracy was significantly higher than novices both in short and long conditions. Overall, non-routineness of flight situation does not have any impact on SA performance of experts, while it has a critical impact on SA performance of novices.

한반도는 판 내부지역으로서 지구조적 과정이 느리게 진행된다. 그 결과 지진발생빈도가 낮으며 불규칙한 지진발생특성을 보인다. 우리나라에는 약 1900년 간의 역사지진기록과 약 100년 간의 계기지진자료가 있어 지진발생특성 연구에 중요한 정보를 제공하고 있으나, 이들 지진자료를 이용할 때에는 자료의 신뢰성과 정밀도에 유의할 필요가 있다.

This paper presents the on-vehicle information system that displays the states of the vehicle in brief words instead of symbols. Main functions of this system include a system check function, trip function, warning function, and clock function. With this system, a driver can obtain all sorts of useful information related to various conditions of the vehicle, and if any problem arises in the vehicle, he can recognize it by the displayed words with a warning sound. Also, this system is very helpful for safety driving because it displays whatever a driver wants to have concerning trip information. By experimental test and driving test, the development system shows good results for each function.

This paper studies on the visibility of dashboard in forklift. As part of the real setting devised for this study, 1. Important evaluation by males experience in forklift driving, 2. Icon cognition experiment, 3. Gage cognition experiment, subjects were asked to estimate the important evaluation, sketched to icon and gage position on the screen. Subjective evaluations were carried out by semantic differential method, sketch method, sketch method, then analyzed by consistency test, frequency rate and T-test. I gather the results concerning the relationship between consistent answers and cognition rates of dashboard understand the conditions which create a desired instrument panel.

Recently, Most of diverse noise of vehicles has decreased competitively according to development of the automotive manufacturing technology. Especially, Passenger car manufacturers has been conducting buzz, squeak and rattle(BSR) noise test as a method of the noise evaluation tests to reduce an unpleasant sound from interior parts on the driving the car. The purpose of this paper is to confirm the change of the noise generated in the product after the reliability evaluation. Here by the BSR test procedure used the test regulation of 'G' company.

In this paper, BSR noise from an instrument panel of a vehicle are investigated with integrated experimental methods. First, potential source regions of the instrument panel for BSR are localized by using the module-excitor and near-acoustic field visualization system. Then, subjective evaluation of BSR nosie from the detected potential noise source regions is made with the Zwicker's loudness and time-varying loudness methods.

최근 자동차에 사용되는 조명은 LED가 주를 이루고 있다. 자동차 실내조명, 계기판 등에 사용되는 내부 조명의 경우 대부분 LED를 적용한 제품이며, 헤드램프, 후방 램프 및 방향 지시등과 같은 외부 조명의 경우도 LED로 교체되고 있다. 특히 LED 기반 헤드램프의 경우 과거 3500cc 이상 승용차 등에 한정되었으나 현재는 그 이하 레벨의 승용차 및 SUV 차량으로 범위가 빠르게 확산되고 있다. 고효율, 긴 수명 및 빠른 응답 속도가 장점인 LED를 차량용 조명 광원으로 사용함으로써 기존 할로겐램프나 HID 광원의 대체재로서의 전환이 활발히 이루어지고 있다. 할로겐램프의 경우 청색보다 적색 파장의 광량이 많은 관계로 황색에 가까운 백색을 보이며, HID 램프의 경우 할로겐램프보다는 백색 계열에 더 가깝다. 하지만 LED 램프는 파장의 순도가 높아 보다 완벽한 백색 구현이 가능하다. 또한 단순한 기능을 지닌 헤드램프에서 지능형 헤드램프로의 발전이 빠르게 이루어지고 있다. 이에 따른 LED의 수요 또한 증가할 것으로 예상된다. 향후 고효율 LED 소자의 개발과 함께 자동차용 LED 조명에 대한 적용은 급속도로 진행될 것으로 예상되며, 앞으로 자동차 조명 분야에서는 'LED 헤드램프/후미등 기술+IT 기술(센서+통신)'이 융합된 형태로 발전할 것이다. 본고에서는 LED 자동차 융합 기술 동향 및 전망에 대해 자세히 기술하였다.

Achievement degree can be improved by display offering more effective process about cognitive, pattern recognition than making observers use memory, integration, and cognitive process of control. And this research is proved by several scholars' researches [4][5][7][9]. In this study, researches was conducted about cognition according to layout of object in instrument panel. To decide layout of instrument panel, Cognition value was preferentially decided about all location. And then, objects are arranged to correct position of low cognition following the inferior procedure about each location. As a result, we get conclusion that gauge location is taken in high importance order through mechanical importance degree bringing huge damage during driving forklift-truck.
