The purpose of this study is to describe the precise nature ofergonomists(CPE). CPE job analysis included the tasks performed at present and the tasks which might be performed in the future by CPE. The questions also included which tols, knowledge and academic background are required for the CPE job at present or in the future. The clear job description will help people to understand the business area of CPE and to develope curiculum in job training.

Objective: to improve agricultural working environment using tools and equipments. Background: most existing tools currently used, in fact, are discrepant from human factor guidelines so that they are still exposed to the musculoskeletal disease. Method: the provided tools and equipments are mostly designed considering human factor engineering or usability engineering in a way to avoid musculoskeletal disease. Results: propose the top-down procedure and usability engineering steps to evaluate them for the system design suitability. Conclusion: apply them conveniently into rural environment to help farmers working environment.

A study on analyze the effect of positive and negative contrast for user performance on the VDT tasks);text typing, text deiting, and searching task) has been performed. The performances were measured in terms of the completion time and the number of errors. The results of each VDT task are followings. In the text typing task and the searching task, the performances measured by the number of errors were better at the condition of negative contrast than at that of positive contrast. In the text deiting task, the performance showed a reverse tendency.

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.

This paper discusses the gereral principles to be considered in the design of usef interfaces of graphics packages and presents a top-down design process in systematic way. The effective and convenient user interfaces are analyzed based on human factors criteria and we discuss the properties and application requirements of typical interaction techniques which support primitive tasks. The choice of an interaction technique has a set of input device prerequisites to be met.

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.

Maximizing profit is the most significant object of commercial places. Especially for some places where its atmosphere is main concern of customers like $Caf{\acute{e}}s$, interior design is crucial. Thus it needs to evaluate human emotion and preference. Human Sensibility Ergonomics which is recently signified in various fields is an attempt to quantitatively analyze factors of human sensibility and apply it to design operation. This study attempted to infuse human sensibility ergonomics into $Caf{\acute{e}}$ interior design and analyzed preferable $Caf{\acute{e}}$ interior design factors. Because most $Caf{\acute{e}}s$ have their own target customers, so we assumed four different target customer groups divided by their age and gender groups in each age group. As a result, the difference of each group could be examined. Middle-aged group and males have main interest in the intensity of luminance, i.e. the brightness, whereas youths and females attach importance to both quality of light and color. In addition, there is a tendency for middle-aged group and males to see $Caf{\acute{e}}$ as a public place while young people and females recognize $Caf{\acute{e}}$ as a place for entertainment. Taking the result of this study into consideration can lead to successful $Caf{\acute{e}}$ interior design for specific target customers.

In this paper, we consider the validity of a human probabilistic learning model applied to the perdiction of errors associated with the absolute identification of tones. It is shown that the probabilistic learning model describes the human error process adequately. The model parameters are estimated by two methods which are the method of maximum likelihood, and the method of mement. The MLE version of the model has the better predictive power but the ME version is more readily obtainable and may be more practical.

PDAs(Personal Digital Assistants), one of the typical mobile devices, are examined in this study to identify the factors affecting their usability. This study focuses on the menu design of PDAs. Three factors including menu extension method, menu structure, and screen orientation were manipulated in a usability experiment. Task completion times, error rates, and degree of subjective satisfaction were measured. Guidelines for designing a PDA menu are proposed based on the experimental results.
