We determined the concentration of glucose, cholesterol, AST and ALT in sera of man workers (n=3,247) had health check-up at hospitls in Jeonbuk area. The mean of concentration of glucose, cholesterol and AST of all workers were increased by 0.1%, 14.9% and 33.0% over than the mean of reference, but the mean of ALT was decreased by 0.8% from it. The rate of workers showed abnormal value of glucose, cholesterol, AST and ALT were 9.7%, 25.4%, 23.7% and 5.5%, respectively. The mean of glucose, cholesterol and AST in each age group were increased over than reference, but the mean of ALT was decreased except in fifties. The rate of the workers in each age group showed an abnormal concentration of glucose, cholesterol, AST and ALT were in 5.6~6.7%, 14.9~31.1%, 20.4~29.2% and 5.2~6.0%, respectively.

Vision-based tracking has been proposed as a means to efficiently track a large number of construction resources operating in a congested site. In order to obtain 3D coordinates of an object, it is necessary to employ stereo-vision theories. Detecting and tracking of multiple objects require an entity matching process that finds corresponding pairs of detected entities across the two camera views. This paper proposes an efficient way of entity matching for tracking of construction workers. The proposed method basically uses epipolar geometry which represents the relationship between the two fixed cameras. Each pixel coordinate in a camera view is projected onto the other camera view as an epipolar line. The proposed method finds the matching pair of a worker entity by comparing the proximity of the all detected entities in the other view to the epipolar line. Experimental results demonstrate its suitability for automated entity matching for 3D vision-based tracking of construction workers.

As the importance of artificial intelligence grows rapidly and emerges as a leader in technology, it is becoming an important variable in the next-generation industrial system along with the robot industry. In this study, a safety system was developed using deep learning technology to provide worker safety in a robot workplace environment. The implemented safety system has multiple cameras installed with various viewing directions to avoid blind spots caused by interference. Workers in various scenario situations were detected, and appropriate robot response scenarios were implemented according to the worker's risk level through IO communication. For human detection, the YOLO algorithm, which is widely used in object detection, was used, and a separate robot class was added and learned to compensate for the problem of misrecognizing the robot as a human. The performance of the implemented system was evaluated by operator detection performance by applying various operator scenarios, and it was confirmed that the safety system operated stably.

Human Engineering has an intention of design to keep the best condition of man-machine system. Hitherto the conception of design has been used to include existing engineering, as mechanical engineering and electric engineering. But the manufactured goods which to be made these process seem to be fully equipped on physical function, but faults come out discountent repeatedly to users. Accordingly, the development of industrial design has been demanded for improving functional design. It is considered that industrial design has aesthetical sensation. In actually, it must be 1. to provide for utility and safety, 2. easy for maintenance, 3. cheap at cost. 4. possible for sales appeal, 5. and good on appearance. As taking into consideration above five conditions, however, for 삯e sake of comprehend to human being about operating method of machinery and equipment, it should be reflected to design what kind of training way will be needed. Also, it must be considered what a certain extent would be occurred tiredness to human being. in other words. it should be considered the design to be possible the reflect to principle of motion economy, It should not be made adoption of human ability for the designed machinery, it must be adopted the method to consider the design on presuppose about human ability. For study of these actual fact, this paper is summarized the essence of human engineering, and also to find out the methodology as humanistic engineering, It is, Particularly, subdivisionization of operation in flow operation is essential direction of mechanization. Generally. as developing the subdivisionization of operation, it will be lack of satisfaction on operation which worker take charge of. The subdivisionization of operation makes the operation to simple-repetitive, to lose the interest of worker and will be also come into question to the feeling of worker's livelihood. It is human's fundamental desire to have get skilful function or special technique. But the subdivisionization of operation hold in those human's fundamental desire and so that it will likely to lose the sorority of living by this fact. Accordingly, this paper have an operation to hold out the methodology on presuppose about human ability.

Objective: The purpose of this study was to find out what kind of change in death rate when job stress is solved by calculating job stress relieve coefficient. Methods: This study used the data of the fourth working condition survey. Regression analysis was used to determine the relationship between health effects recognition and Death rate per 10,000 workers. After that the recognizing and non - recognizing groups were categorized by health effects recognition, and the differences between the two groups were confirmed by cross tabulation analysis. Results: Regress analysis P-value is 0.011 and $R^2$ is 0.979. Death rate per 10,000 worker increased with the increase in the number of non - health impact recognizing group. The relieve factors were (1) work culture(2.859) (2) physical environment(2.184), (3) improper reward (1,839), (4) relationship conflict(1.646), (5) job requirement(1.613), (6) job autonomy(1.354), (7) job instability(1.334), And (8) organizational system(1.201). The higher the relieve coefficient is, the higher the probability of belonging to the non - health impact recognizing group when there is no job stress factor. Conclusions: When job stress is resolved, there is a high probability that the health impact recognition is reduced, which can lead to an increase in death rate. but according to previous studies, Job stress can cause accidents by reducing the safety behavior of accidents. The job stress management plan should simultaneously consider reducing job stress and increasing health impact recognition.

In the manufacture of automobile suspension modules at a company as parts supplier, the design process includes the detail design and the design modification via structural and fatigue durability analyses considering PoF(physics of failure) of their weldments that are repeated more than four times sequentially. The approval of the design and the release of final drawings follows. For the suspension modules, e.g. control arms and cross member, the man-hours per worker required in the process outlined above can reach as high as 1,414hours. Application of the developed integrated design system can reduce the man-hours of 1,004. In comparison with the conventional design process, this integrated design system reduces the required time by about 40%. If expense is taken into account, a savings of approximately $192,000 is estimated, assuming the design process accounts for 1.5% of total sales for the parts supplier
