Small group activity in Korea was introduced from the United States as QC circle, ZD group movements and the like, but it has developed into a Korean style from so-called factory saemaul panel activities contributing much to the management of enterprises. Based on human motivation theory, the principles to activate small group activity is suggested on which a new diagnosis of small group activity is proposed here. It is consisted of checklist and radarchart. The factor to activate small group activity have been obtained in terms of multivariate analysis for data from the new diagnosis.

This study reviews usability of PC communication softwares with different dialogue types of user interface. Usability test was conducted to evaluate usability of 3 PC communition softwares which are currently utilized in Korea. Learnability was adopted as an index of usability evaluation, so learning time, testing time and scores were measured as dependent variables. It is suggested that softwares with mixing dialogue type(menu, icon, command) which were implemented in window systems environment were not superior to that with command dialogue type.

The sensitivity of the emotion evoked visually by IAPS was attempted to be defined using EEG(electroencephalogram). Twenty university students were participated in this study. Their EEG was measured and analyzed in terms of frequency range such as delta, theta, alpha and beta wave. The results showed that alpha increased, but delta and beta decreased with positive emotional progress. Inter-variation between alpha and delta in F4 and beta variation in P3 were indicative of the evaluation sensitivity of human emotion.

Anthropometric characteristics and considerations of sex differences are essential for the correct design of ergonomic work spaces. This paper is concerned with longitudinal study on the physical growth in the Korean youth. Five hundred and fourty subjects were selected from third year students of high schools, and their records on physical examination during the last twelve years were surveyed by longitudinal method. This study investigated the anthropometric characteristics of physical structure and the shape of physical growth for boys and girls. The result showed that there were significant sex differences in the pattern of physical growth in height.

Hypermedia systems allow the retrieval and representation of multimedia in- formation such as text, graphics, image and voice/sound using navigation and browsing mechanisms. In this study we developed a hypermedia system which provides hierarchical group, local map and cluster view for effective navigation in hyperspace. The system also supports hot link, reference link, move-to link and multiple link to browse the multimedia information space effectively. This system has been designed to integrate the navigation, browsing and searching function of the hypermedia system in hyman factor perspective and provides the user-friendly user interface mechanism.

This article reviews the effects of VDT tasks on multiple resources for processing and storage in short-term working memory. MD and PD method were introduced toevaluate the modalities (auditory-visual) in the multiple resources model. The subjects conducted 2 sessions of 50 minites VDT tasks. Before, between and after VDT tasks, MD, PD task performance scores and CFF(critical flicker frequency0 values were measured. The review suggested that the modalities of human information processing in working memory were affected by VDT tasks with different task contents.

The job design was frequently tried in many enterprises in order to give workers the job satisfaction, but there remains obscure about what kinds of human factors in job yield the satisfaction. This study is concerned with an experimental method for job design to account for such findings that work with conveyor gave workers unsatisfaction, and that enlarged job of work resulted in high job satisfaction.

Objective: This research focuses on the working environment of office workers and aims to propose an ideal seating posture and chair design. Background: Generally, office workers having to seat in a fixed posture for long periods of time tend to suffer from an increased rate of musculoskeletal disorders. Method: The measurement and survey of 123 office workers on their working conditions and literature survey will lead to a suggestion of an ideal seating posture and workstation design theory. Results: Work environment satisfaction appeared low for chair and desks. Work-related pain over the last year was experienced among 47.2% of the respondents in shoulder (34.2%), neck (30.9%). Observation of working posture revealed that only 27.6% of workers utilize backrest during work. Conclusion: Office work embodies many situations where risks of musculoskeletal disorders may be high. Thus, the seated workplace must be set up to allow proper seating posture for workers. Application: The results of this study can be applied as baseline data for preventing musculoskeletal disorders of office workers.

The aim of this paper is to improve the design of a pair of axilla crutches through quality function deployment(QFD) and discomfort experiments. User needs for the crutches, as well as the engineering characteristics which have influence on the ergonomic quality of crutches were determined from the interview with many users. This information was entered in the house of quality, and the results show that the axillary pad and grip are the most important quality factors. And the results from the discomfort experiments confirmed the QFD output. A prototype reflecting the QFD results was proposed. The present study demonstrated how QFD approach can be a methodological tool geared to greater ergonomics consideration in product design.

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.
