To investigate industrial fatigue and low back pain, the questionaire survey for subjective symptoms of fatigue and low back pain was carried out among 591 male workers aged 20-55 employed in an automobile industry in Korea. Workers participated to this study were divided into low back pain group(LBP) and control group, according to the self-reports by written questionaires. The subjective sysptoms of fatigue comprised three groups of 10 items each, representing dullness and sleepiness(level of cerebral activation), difficulty in concentration(level of motivation) and bodily projection of fatigue. The resultant data were processed for $\chi^2-test$, t-test and a pearson's correlation coefficient to confirm the relationships. The results were as follows: 1. 30 items of fatigue subjective symptoms exeptone item, 'lack in perseverance', were directly associated with low back pain. 2. The percentage of fatigue complaint were sig nificantly higher in LBP group. 3. Of the 30 items of fatigue subjective symptoms, the highest percentage was accounted for 'eye strain'(27.9%), followed by 'whole body feels tired' and 'legs feel heavy'(22.9%), 'feel like lying'(21.4%), 'feel a pain in the low back'(18.7%), 'feel drowsy'(16.4%) and 'feel stiffness in the neck or the shoulders'(16.2%) in the order of sequence. 4. The average weighted score for the first group of fatigue items(dullness and sleepiness) was the largest among three groups and was followed by the second group(difficulty in concentration) and the third group(bodily projection of fatigue) in the order of sequence, suggesting the heavier shift work stress of the workers. 5. In the groups of the aged 30-40, work duration of 5-7yrs, heavy work amount and irregular work speed, significant high fatigue complaints were revealed in terms of eye strain, whole body feels tired, legs feel heavy, feel like lying, feel a pain in the low back and feel stiffness in the neck or the shoulders. 6. A significant negative correlations were shown between age, work duration and eleven subjective symptoms while positive reciprocal correlations were shown between eleven items with one another.

To investigate industrial fatigue and low back pain, the questionaire survey for subjective symptoms of fatigue and low back pain was carried out 305 nurses in general hospital in Korea. Nurses participated to this study were divided into low back pain group(LBP) and control group, according to the self-reports by written questionaires. The subjective sysptoms of fatigue comprised three groups of 10 items each, representing dullness and sleepiness(level of cerebral activation), difficulty in concentration(level of motivation) and bodily projection of fatigue. The resultant data were processed for $x^2$-test, t-test to confirm the associations. The results were as follows: 1. 28 items of fatigue subjective symptoms exept two item, 'feel thirsty and 'feel ill', were directly associated with low back pain. 2. The percentage of fatigue complaint were significantly higher in LBP group than control. 3. Of the 30 items of fatigue subjective symptoms, the highest percentage was accounted for 'legs feel heavy', 'eye strain', 'feel stiffness in the neck or the shoulders' followed by 'feel like lying', 'whole body feels tired', 'feel a pain in the low back', 'feel drowsy' and in the order of sequence. 4. The average weighted score for the first group of fatigue items(dullness and sleepiness) was the largest among three groups and was followed by the second group(difficulty in concentration) and the third group (bodily projection of fatigue) in the order of sequence, suggesting the heavier mental and shift work stress of the female workers.

Objective: To find the related factors and the symptoms of menopause in male workers. Method: This Study is targeted on 369 people(40's; 219, 50's; 150) who are married and being 40 years old or more with working for over ten year. Results: First, the symptom of menopause in proportion to age is, 40's appeared in order of 'Decrease in ability to play sport', and 50's appeared in order of 'Less strong erection'. Second, the symptom of menopause was higher from the difference between general characteristic and work characteristic when people have old age. Third, the symptom of menopause was lower from difference among life habits when people do some exercises regularly, and no overeating. Fourth, the symptom of menopause was much lower from the difference of subjective health state when people feel comfort without any disturbance to their daily life, as they feel much younger than their ages, and feel healthy. Fifth, the variables affected to the symptom of menopause were age, do exercise whether or not, subjective health state when people feel much younger than their ages, and feel healthy. Conclusion: the symptom of menopause is not only for women but also for men. And it is not only for people who are old but we could find some abilities from young ages, too.

Objective: The objective of this study is to understand the effect of angle and curvature of push-return switches, which are external factors in the operation environment inside the cars, on the feel of operation and to propose optimum alternatives. Background: Customers' needs for products are changing from functional and performance aspects to customer-led type where customers can reflect on their needs on the products. The operation inside cars is executed by HMI. The push-return switch is utilized as the most intuitive mode of HMI; therefore, this push-return switch, which is widely used, has to be developed by assessing the preference and satisfaction of the customer. Method: The angle and curvatures, which are external factors that affect the feel of operation, are drawn through surveying the preceding research literatures. The stages to construct alternatives in experiments are as follows: (1) the tactile switch is replaced after dismantling the switch assembly to evaluate the internal characteristics proposed by preceding researches, (2) a drawing is prepared by using a design software, is printed using 3D printer, and then it is attached on the switch assembly, and (3) evaluation for satisfaction of operation is carried out by using a driving simulator. Results: Both the angle and curvature that are external factors of switch significantly affect the feel of operation. However, interaction between the two factors is found insignificant. Therefore, an optimum alternative is proposed considering the experimental outcomes. Conclusion: This study evaluates the satisfaction in operation that affects the feel of operation environment inside the cars. Based on the study results, a guideline for switch design in the center fascia is proposed. Application: This study is expected to be used as basic data for designing automotive switches, as well as switches in the industries similar with the operation environments of cars.

A technology that allows users to feel the elasticity of fabric through force feedback in the fashion and textile fields is very helpful to related manufacturing and sales areas. Currently bundle of fabrics, so called Swatch, is the only available way for the designer, manufacturer and the end-user to feel the fabrics. Images and video clips provide only visual characteristics, hence touch and stiffness are also very important characteristics to check beforehand. A study is conducted on a haptic device, which estimates the amount of change in the length of the virtual fabric and generates resistive force so that the user could feel the fabric stiffness. Since cables that can only transmit the tensile force are used, a force realization method is proposed, and it is verified numerically and experimentally.

다른 사람이 차 문에 손가락을 찧는 것을 보면 마치 내게 일어난 일처럼 움찔하지 않는가? 소설을 읽고 감정을 느끼는 것은 왜일까? 이는 공감하기 때문이다. 공감이란 "다른 사람이 느끼는 감정을 목격하거나 기대하는 순간에 정서적으로 반응하는 것"이다. 즉, 공감은 함께 느끼는 것이다. 본 논문에서는 이러한 공감을 측정하는 방법에 대해서 기술하고자 한다. 사람의 감정을 측정하는 것은 쉽지가 않다. 사람들이 소통하는 방식이 다양하기 때문이다. 사람마다 공감을 표현하는 것과 느끼는 감정이 다 다르기 때문에 다양한 방법의 데이터 분석이 필요하다. 이를 위해 본 논문에서는 짧은 단위(1초 단위: 응, 좋아, 아하 등)의 음성과 Head Nodding을 이용한 새로운 공감 측정방법을 제안하려고 한다.
