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.

In this study, thr air flow-meter was developed which can control the air flow rate with the load of the engine and to measure air flow rate using Karman vortex. In the experiment, the sensor consists of an air channel with a triangular strut(bluff body) to generate the Karman vortex street, a couple of ultrasonic transmitter and receiver, to detect vortex. The results obtained from these experiments are as follows;air flow rate can be measured by detecting Karman vortex with ultrasonic sensors, vortex frequency is linearly proportion to the air flow rate. To measure air flow rate, the width of bluff body and the number of stability plate used in air flow rate sensor are 7㎜ and 2. Air flow sensor developed at this experiment can be used for Internal combustion engine, and for various purposes, too.
