  • One of the most important factors that affect a person's risk of injury in a motor vehicle crash is the age of the person. This study investigates the characteristics of crash injuries among young, middle-aged and older drivers and occupants. Based on the comprehensive claim data from automobile insurance from 2000 to 2007, this study examines in great detail the drivers and occupants injury body regions and severity by age in car-to-car frontal crashes. It has been shown that elderly drivers and occupants suffer more injuries at a chest region compared to the middle-aged group. This research calls attention to the need for design to make vehicles more protective for older drivers in car-to car frontal crashes.

  • Abstract The purpose of this study was to propose a new size-spec. which was applied to four frontal bodytype -X, Y, A and H type-of adult women. Control dimensions of the upper garments were stature bust girth and hip girth. And those of lower garments were waist girth and hip girth. To establish the interval of the control dimensions means and standard deviations were used. By distributing the data of 486 subjects a new size-spec. was proposed. According to the new size-spec. in case of upper garments about 45.7% of subjects were covered by 37 size-speces. and lower garments about 85.9% were covered by 36 The strong point of new size-spec. is to consider the formal feature of each bodytypes. So by trying to apply the new size-spec. to rady-made garments comfort and fitness of those are satisfied.

  • This study aimed to classify high school girls' frontal body shapes into a few representative types and to give each type a name to symbolize its typical shape clearly. Subjects consisted of 205 high school girls aged 15 through 17 years attending high schools in Kwangju. 55 anthropometric and 29 photographic measurements were taken from each subject. The data were reduced to a few factors and the main factors composing the frontal body shapes were classified into 3 clusters. as the results the frontal body shapes of the high school girls were classified into H, X, Y types.

  • In order to design establish automation or optimization of the machining process, predictions of the forces in machining are often needed. In this paper, a theoretical model in face milling is presented based on Oxley's predictive machining theory, where the cutting forces are predicted from input data of fundamental work material properties, tool geometry and cutting conditions without any preliminary cutting experiment. A simulation system for the cutting forces in face milling is developed using the model. Milling experimental tests are conducted to verify the model and the predictive results are compared and discussed with the experimental results.

  • 입체음향 생성을 위한 기존의 방법은 크게 바이노럴 녹음기법과 머리전달함수(HRTF)를 이용한 바이노럴 합성 기법으로 크게 나눌 수 있다. 바이노럴 기법으로 생성된 이러한 입체음향은 재생을 위해 역 필터와 Equalization 곡선을 선택하게 되는데 이것은 음질에 중요한 영향을 주게 된다 본 논문은 재생시 음질의 향상을 위해 적합한 역 필터 설계와 Equalization 곡선의 선택방법을 제시하고 트랜스오럴 시스템 설계 시 신호처리로 인한 음질의 저하를 최소화하기 위해 스피커의 위치를 청취자의 머리 뒤에 놓는 방법을 제안하고자 한다. 그리고 청취자의 정면에 스피커를 한 개 추가하여 정면의 음상을 강화하고 3 채널 바이노럴 녹음기법(1)으로 만들어진 음원에 대한 호환성을 갖게 한다. 마지막으로 이 제안된 모든 방법들을 실시간으로 재생하는 시스템을 구현한다.

  • Optimized section shape of aluminum bumper backbeam for enhancing the front high speed crashworthiness was investigated. Front body analysis model of a convertible vehicle was built up and parameter studies were carried out with changing the inner rib shape and the section thickness distribution. First an inner rib shape displaying most efficient structural performance was selected. Next, for the selected section the effect of section thickness combination was examined. Also, a light weighed backbeam section displaying crash performance over the current design was suggested. Finally RCAR front low speed impact analyses were carried out for the optimized models.

  • 본 논문에서는 사람의 정면 얼굴을 찍은 컬러 동영상에서 얼굴의 각 구성 요소에 대한 특징점들을 추출하여 3차원 개인 얼굴 모델을 생성하고 이를 얼굴의 표정 움직임에 따라 애니메이션 하는 방법을 제시한다. 제안된 방법은 얼굴의 정면만을 촬영하도록 고안된 헬멧형 카메라( Head-mounted camera)를 사용하여 얻은 2차원 동영상의 첫 프레임(frame)으로부터 얼굴의 특징점들을 추출하고 이들과 3차원 일반 얼굴 모델을 바탕으로 3차원 얼굴 특징점들의 좌표를 산출한다. 표정의 변화는 초기 영상의 특징점 위치와 이 후 영상들에서의 특징점 위치의 차이를 기반으로 알아낼 수 있다. 추출된 특징점 및 얼굴 움직임은 보다 다양한 응용 이 가능하도록 최근 1단계 표준이 마무리된 MPEG-4 SNHC의 FDP(Facial Definition Parameters)와FAP(Facial Animation Parameters)의 형식으로 표현되며 이를 이용하여 개인 얼굴 모델 및 애니메이션을 수행하였다. 제안된 방법은 단일 카메라로부터 촬영되는 영상을 기반으로 이루어지는 MPEG-4 기반 화상 통신이나 화상 회의 시스템 등에 유용하게 사용될 수 있다.

  • To classify the bodytype at sight of front line of the body, 20 to 59 year-old 484 females were examined. 73 photographic and 16 anthropometric measurements were taken to each subject. The indices were used to obtain the shape factor of the bodytype. The principal component analysis was performed to obtain the shape factor of the front line of body and 6 factors were abstracted. The factor score was better than the measurements as the independent variable in applying the cluster analysis to classify the shape. As the result of the cluster analysis, the shape of the body at sight of the front line was classified in 4 types. It was named X, Y, A, H type. Considering the sizes, Y type was obese and H type was lean characteristically.
