In this paper, methods of human figure representation in computer graphics are described. Many applications of the human figure representation are found in areas including industry, advertisement, and cartoon production and further research for the methods that show the human figure more realistically is ex- pected. Two analytic methods for human model, kinematics and dynamics, are ex- plained and the characteristics of the man-machine interface systems that include human figure representation are presented. Various techniques of the human figure representation based on kinematics or(and) dynamics are discussed and representation methods of human body segments such as hand, face, spine are introduced in this paper.

The object of this research is to develop an interactive computerized graphic program for graphic output of velocity, acceleration and motion range of body task reference point. Human motions can be reproduced by scanning (rate = 1/60) the vidicon image, at same time, C.O.G of body segment group, and the results are stored in an Apple II P.C. memory. The results of this study can he exteneded to simulation and reproduction of human motions for optimal task design.

Because the moving visual acuity is less than the static visual acuity, a new headlight system was designed and manufactured to make reparation for that. Then the new headlight system was built in a passenger car and some experiment was achieved. When the car is accelerated the luminous flux of headlight is augmented. When the speed of the car was increasing, the new system was effective, but when the car was decelerated the system was less effective.

This paper deals with the legibility of Korean characters(Hangeul) on car number licence plates. We focus of the height-width ratio as key factor affecting the legibility in experimental procedures. The results of experiments are; i) For vertica characters, the vest height-width ratio was 1:1 for 3 throuth 5 stroke characters, and 4:5 for 6 and 7 stroke characters. ii) For horizontal characters, the best height-width ratio was 1:1 for 3 through 5 stroke charcters, and 5:4 for 6 and 7 stoke characters.

In this study, four alternatives for the arrangement of Korean alphabets on computer keyboards are developed and analyzed to find the better design than the KS(Korean Standard) keyboard. Among the developed four modified models MOD 1 to MOD4, we suggest MOD3 as the best design which incorporates the keys usage frequencies and the compatibility of present standard.

Objective: The aim of this paper is to introduce ergonomic guidelines and intervention procedures for farm workers. Background: It is necessary to ameliorate the conditions of risky and hazardous work for farm workers. Method: Various references and books have been reviewed to assess ergonomic guidelines and intervention procedures for farm workers. Results: Human centered intervention has become an important approach not only to prevent musculoskeletal disorders but also to enhance the efficiency of work for farm workers. Conclusion: Farm work should be improved by active cooperation with researchers in field of ergonomics. Application: These results can be used to provide baseline information for more effective improvements of farm work.

Anthropometric data is most basic materials in the all studies related with it. Therefore, in anthropometric data, not only consideration of the state of variance, but more various analysis is needed. This study selected the 13 parts that properly show a whole characteristics of human body and, anthropometric data were obtained through the actual measurements for male and female workers who were engaged in production factory. And, to interpret anthropometric data, principal component analysis of multivariate analysis methods was applied.

This study is to investigate the fitness of tight skirt in moving lower limb. The fit- ness was tested by measuring the step length, stride length, maximum stair step height. One humdred and twenty female subjects participated in the experiment. It was shown that the tight skirt caused the most reduction in the maximum stair step height among the five lengths measured. It was also shown that the long tight skirt limited the maximum stair step height more than the mini tight skirt.

Compatiblity is a very generalized concept that has substantial applicablity to various aspects of human factors. It refers to the spatial movement, or conceptual relationships of stimuli and of responses, individually or in combination, which are consistent with human expectations. In this paper, first, several remarks which should be considered in designing the visual display and control of automobile are considered. Also, two advanced designs of visual display and control are suggested based on the compatibility principles.

This article developes a cost-effective on-line measurement system of R - R intervals in ECG. The system is composed of a R peak detector, a timer and an Apple II computer (a 6502 microprocessor and memories). The system measures the R - R intervals in msec and stores them in a disk, for off-line analysis. A circuit diagram of the R peak detector and programs for controlling the microprocessor are presented.
