This study aims at providing some basic material to be made use of for establishing plans through which one can reduce job-related stress, through conducting a survey on the sources of stress and then distinguishing its symptoms by the sources. As the methods of the study, we conducted a questionnaire survey of some selected medium enterprises' employees in the National Capital region and analysed the results. The questionnaire was designed by using the dynamic stress model of Cooper and Eaker and consisted of 85 questions to examine the sources of stress, the characteristics of personalities, and symptoms by each type of stress. The total valid respondents were 392 persons indicating 65.3% of the response rate. For analysing the results, a rating scale was used, and the reliability and validity were tested by using Cronbach's alpha coefficient. As the result of the study, those workers in medium enterprises were found to be put under much stress by responsibility, physical environment factors and career development factors and so on. As physical symptoms of job-related stress, eye fatigue, stiffness in their shoulders, headache, worry or anxiety, and waist ache presented most in the respondents. In addition, as behavioral symptoms, chronic fatigue was most indicated. In organizational symptoms, dissatisfaction about the company and lack of self-motivation for the job performance were found to show most. Moreover, the results indicated that the closer personalities to those appearing in persons mostly of type A they had, the more they were put under intensive stress by the vagueness of their roles and responsibility among all the job characteristics.

This paper describes a new approach to estimate induction motor speed from terminal voltages and currents for speed-sensorless vector control. Tills algorithm is based on Model Reference Adaptive System(MRAS) The proposed technique is simple and robust to the variation of motor parameters Specially, this algorithm is not affected by the variation of stator resistance and It does not require any pure integration at all. The validity of this new approach is proved by simulations

이 연구의 목적은 국내 자동차 번호판의 가독성 향상을 도모하기 위하여 자동차 번호판의 소재와 형식을 규명하기 위한 것이다. 실험은 청색과 황색, 반사식과 비반사식, 1열식과 2열식의 3가지조건에 따른 다양한 번호판 규격을 제작하여 사용하였다. 가독 실험을 실시한 결과 다음과 같은 결론을 얻었다. 1) 주간의 경우 번호판이 2열식 번호판 보다 1열식 번호판이 가독거리가 22% 길게 나타났다. 2) 야간의 경우에는 반사식이 비반식의 경우보다 14.7%정도 가독거리가 향상되는 것으로 나타났다. 3) 청색 배경에 반사식 황색 글자색이 반사식 황색 배경에 청색 글자가 6.4% 가독성이 향상 되는 것으로 나타났다. 또한, 비반사식의 경우에는 청색배경에 황색 글자, 황색배경에 청색글자의 뚜렷한 차이가 없는 것으로 나타났다. The purpose of this study is to propose the improved style and material of license plate, which is the exterior panel of the automobile indicating the legal registration codes, in order to provide the observers with the better readability than that of the current number plate in Korea. For the empirical study, the sample license plates were manufactured on three criteria, such as single or double line, reflective or non-reflective, and yellow captions on blue background or blue caption on yellow background. The results are as follows; 1) The average readable distance of the single line samples plates, in the daytime, is longer than that of the double line ones by 22%. 2) The average readable distance of the reflective sample plates, in the nighttime, is longer than that of the non-reflective ones by 14.7%. 3) The reflective yellow caption on blue background were prefectly read farther away than the blue captions on reflective yellow background by 6.4%. Also, there was no significant difference between non-reflective color contrasted samples; blue on yellow background and yellow on blue background.

The purpose of this Study is to confirm the impact of noise on subject accomplishment as well as physical/mental load, and evaluates the effects of noise-masking and earplug. 15 college students participate in the test, and the comparison is performed by executing four projects according to conditional categories of noise environments; control condition, noise condition, earplug condition, and noise-masking condition. Noise in the field site of the H manufacrurer was used as the noise source, the general job aptitude test which consist of linguistic ability, math ability, perception ability, reasoning ability was used as the task of this project. To estimate physical/mental load evaluation, we uesd the heart rate R-R interval, Criteria flicker fusion freguency(CFF) and measured NASA-TLX workload for subjective evaluation. As the research outcome, it is shown that there is a meaningnd difference for the project task score, dropping rate of CFF, the heart rate, and NASA-TLX subjective evaluation score according to conditions of noise environment. Therefore, the impact of noise on capability of subject accomplishment as well as physical/mental load was confimled along with the effects of using earplug and noise-masking.

김대호,박근상,Kim, Dae-Ho,Park, Keun-Sang 대한인간공학회 2007 大韓人間工學會誌 Vol.26 No.1

The purpose of this study is to assess the welfare level for shift workers by means of their satisfactions to the jobs in manufacturing environment. As a measurement tool of job satisfaction, we use the JDI(Job Descriptive Index) which can ensure reliability and are widely used. Measurement factors are investigated by means of the duty, payment, promotion, supervisor, co-workers, and general job satisfaction of shift workers. For the application of job satisfaction, 109 workers, 12-hour shift workers in domestic five companies related with manufacturing industry are considered. They treat general facilities in night shift work. The result of this study may be used as a strategic data of welfare policy for improving the welfare level of shift workers.
