Purpose: This study was conducted to investigate and analyze the association between stress from shift and non-shift work as well as the effects living habits have on eating habits in order to identify why and how workers can improve their health and form proper eating habits for higher working efficiency. Methods: The subjects of this study were 361 workers from K manufacturing company from April 7 to 11, 2014 and they were surveyed using a questionnaire. The subjects were divided into two groups according to working pattern: shift workers (n = 216) and non-shift workers (n = 110). Results: In the general characteristics, there were significant differences in age, work career, work time, marriage, monthly income, and education levels between the two groups. For healthy behaviors, significant differences in subjective health status, moderate physical activity, drinking, smoking, and sleep time were observed between shift workers and non-shift workers. For eating habits, scores of non-shift workers having a regular mealtime, balanced meal composition, and vegetable and seaweed intakes were significantly higher than those of shift workers. The sum score of dietary habits in non-shift workers was also significantly lower than that in shift workers (p < 0.05). Total job stress score did not significantly differ between the two groups. Conclusion: The sum of eating habit scores according to work types was $16.1{\pm}0.6$ in non-shift workers and $14.0{\pm}0.3$ in shift workers. These results suggest that it is necessary to provide food suitable to characteristics of different workers according to work type which should be provided along with daily nutrition counseling to help subjects recognize their status.

Recently, interesting in flexible working has been increased, and some central government and large companies are conducting flexible working. With the conducting of flexible working, workers are able to get a convenience but the cost of managing is increased. In this paper, we suggest a method of reducing the cost and managing efficiently. Our study determines the position of the workers using indoor localization techniques through the Wi-Fi fingerprint and smartphone, and records the office hours. The previous time and attendance systems have to install attendance recording device(e.g. Fingerprint Attendance System, RFID Card Attendance System) and are needed to manipulate manually. Our system doesn't need to install extra devices, and also doesn't need to manipulate manually. Our system automatically records the office hours. Also most of previous time and attendance systems have another weakness. They only record data when workers start and stop work. But our system exactly records office hours for each workplaces. In this paper, We introduce an effective time and attendance system in variety flexible working. Our experiments shows that our system workers' detected office hours accurately. The accuracy of our time and attendance system was 98.7%.

In this study changes in biorhythm are observed by measuring heart rate variabilities in order to verify, compare, and evaluate stresses in guard duties of guards and CCTV monitoring works of staffs serviced in practical guard sites. Guard duties and CCTV monitoring works similar to a practical situation are implemented for nine students in the department of security at K University over 150 minutes. In the results of observing heart rate variabilities and autonomic function tests for six times with an interval of 30 minutes, the heart rate variability (HRV) in CCTV monitoring works represents lower levels than that of guard duties. Also, in a stable condition the guard duties for 30 and 60 minutes exhibit lower levels than that of 90, 120, and 150 minutes. Regarding SDNN, CCTV monitoring works show higher levels that guard duties and the guard duties for 30 and 60 minutes represent lower levels than that of 150 minutes. In autonomic function tests, there are no differences in TP between groups according to guard duties and CCTV monitoring works. Also, the guard duties for 150 minutes represent more differences in TP compared to that of 30 minutes. The interaction between the duty type and the duty duration is presented. In the case of LF, guard duties for 150 minutes show large differences in duty duration compared to that of 60 minutes. In the case of HF, the CCTV monitoring work group shows higher levels than the guard duty group in which the guard duties for 120 and 150 minutes represent higher levels than that of 30 minutes. The interaction between the duty type and the duty duration is presented. In the case of the LF/HF ratio, the guard duty group exhibits higher levels than the CCTV monitoring group. Also, there is an interaction between the duty type and the duty duration including the difference in durations. The CCTV monitoring works represent lower heart function activities than the guard duties according to increases in parasympathetic nervous activities. It shows that the long-term CCTV monitoring duty repeated everyday shows a high possibility of increasing the exposures of VDT syndrome and nervous breakdown.

In the context of the COVID-19 era, due to the serious epidemic and heavy workload, medical staff often work overtime. The frequency of overtime work is directly related to organizational trust, so the impact of overtime work is of high importance to medical staff. This study focuses on the role of overtime work and validates the level of organizational trust among healthcare workers. The mediating effect of personal achievement as a mediator between overtime work and organizational trust was also explored. According to the results, both voluntary overtime and inoluntary overtime of medical staff have a positive impact on organizational trust. The results also suggest that personal accomplishment has a mediating effect between overtime work and organizational trust. This study focuses on exploring the impact of medical staff overtime work on organizational trust and proposes options for improving organizational trust among medical staff.

The shipboard working environment of coastal ship is very inferior too the ground working environment and it causes the avoidance of shipboard working and the aging of crew. Especially the air pollution and electromagnetic wave in ships causes an occupational disease. hence to reduce the shipboard working fatigue is necessary by the security of the comfortable shipboard working environment and residence environment. in this paper, first we evaluate the shipboard working environment by using the measurement results of the shipboard air polluting and electromagnetic wave in the sea. And we propose the reduction measures of shipboard working fatigue based on the evaluation results of the shipboard working environment.
