본 연구에서는 업무스트레스 관리를 위해 호흡과 심장박동간의 상관관계를 이용한 최적 호흡법을 유도하고 반복 훈련을 통해 사용자의 건강을 자가 관리하는 시스템을 개발하였다. 일정한 호흡은 심장의 항상성을 유지할 수 있도록 도움을 준다. 심장의 항상성 유지를 통해 업무스트레스 자극으로 인한 심장 리듬의 변화를 빠르게 안정시킬 수 있다. 사람은 개인에 맞는 고유한 호흡리듬을 가지고 있기 때문에, 최적 호흡리듬을 반복적으로 훈련하는 것을 통해 심장의 항상성을 높일 수 있다. 본 시스템은 개인에 맞는 최적 호흡리듬을 찾아서 이를 반복적으로 훈련할 수 있는 시스템을 개발하였다. 그리고 업무스트레스가 높은 콜센터 직원들을 대상으로 검증실험을 실시하였다. 검증실험 결과 자신의 맞는 호흡주기를 사용하여 호흡을 하면 심장의 반응이 안정성을 보이고 부교감이 활성화 되는 것을 확인할 있었다. 개발한 시스템을 활용하면 감정노동자들 중에서 콜센터 상담 업무스트레스를 저감시킬 수 있을 뿐만 아니라, 이를 통한 업무효율증가와 개인의 건강관리에도 많은 도움을 줄 수 있을 것으로 예상된다.

Currently, many punitive damages (or statutory damages) and class action laws are discussed in relation to the consumer damage relief system. It is in the background of the argument that the introduction of such a victim relief system will solve many small and large consumer damages. There are many cases in which the punitive damages compensation or the class action system are introduced in relation to the food safety damage naturally. Although the introduction of such a system can clearly help the consumer to relieve large-scale damage, it can not solve all the problems at once because the company can reject the system despite the introduction of such a system. In particular, class action lawsuits should have the same type of damage, but most of the damage caused by food safety is accompanied by physical harm, resulting in various complications such as the physical characteristics of the victim, the health environment. The class action system may not provide a solution in that the content and type of the damage may be different. In this regard, this study aims to investigate the introduction of the food safety damage relief system through the introduction of an administrative dispute settlement system by an administrative agency that occupies an absolute position in the existing consumer protection from this point of view. In reality, the Food and Drug Administration, which is the largest among government agencies related to food, operates a passive attitude consumer protection system such as function like guidance, supervision and surveillance. And it is necessary to make a complementary proposal. In the current law, there is only a small part of the consumer protection work that is positively legal, and even after the damage is scientifically identified, it is not possible to present the solution to the damage suffered by the consumer through legislation. This is a fact that has been raised. In this paper, we propose a reasonable and rapid disaster relief procedure through a separate mechanism within the administrative agency, which is the administration agency, that the dispute settlement procedure due to food safety damage is insufficient by solving the case through the court through counseling, dispute adjustment and civil proceedings. In order to solve the problem of food insecurity and the food industry, various ways of rational solution of the problem were considered. The possibility of (1) Establishment of a food safety dispute resolution committee; (2) Establishment of a food safety disaster relief committee; and (3) Establishment of a food safety disaster relief committee was discussed. In addition, a plan for the creation of a food damage compensation fund was also proposed.

Background: It is uncommon for patients who have received a permanent implant to remove the spinal cord stimulator (SCS) after discontinuation of medication in complex regional pain syndrome (CRPS) due to their completely painless state. This study evaluated CRPS patients who successfully removed their SCSs. Methods: This 10-year retrospective study was performed on patients who had received the permanent implantation of an SCS and had removed it 6 months after discontinuation of stimulation, while halting all medications for neuropathic pain. Age, sex, duration of implantation, site and type of CRPS, and their return to work were compared between the removal and non-removal groups. Results: Five (12.5%, M/F = 4/1) of 40 patients (M/F = 33/7) successfully removed the permanent implant. The mean age was younger in the removal group ($27.2{\pm}6.4$ vs. $43.5{\pm}10.7$ years, P < 0.01). The mean duration of implantation in the removal group was $34.4{\pm}18.2$ months. Two of 15 patients (13.3%) and 3 of 25 patients (12%) who had upper and lower extremity pain, respectively, had removed the implant. The implants could be removed in 5 of 27 patients (18.5%) with CRPS type 1 (P < 0.01). All 5 patients (100%) who removed their SCS returned to work, while only 5 of 35 (14.3%) in the non-removal group did (P < 0.01). Conclusions: Even though this study had limited data, younger patients with CRPS type 1 could remove their SCSs within a 5-year period and return to work with complete pain relief.

Purpose: The purpose of this study was to investigate the relations between fatigue and work-related factors in workers. Methods: A total of 204 subjects aged between 21 and 59 were selected through convenient sampling. Data were collected with a self-reported questionnaire from May 20 to 31, 2011. Collected data were analyzed with SPSS/WIN 17.0. Results: Difference in fatigue according to general characteristics was significant according to duty type. Difference in fatigue according to occupational characteristics was significant according to work intensity, work speed, demand of work concentration, work space, physical environment, largest weight by hands, vibration, visual demand of work, difficulty of work practice, work stress, and rest hours in holiday. There was a positive correlation between fatigue and occupational characteristics. Stepwise multiple regression analyses showed that educational level, work intensity, and rest hours in holiday were the strongest factors associated with fatigue ($R^2$=.363 p<.001). These factors explained fatigue by 36.3%. Conclusion: The findings of this study may be useful in understanding workers' fatigue and developing more specific fatigue relief programs.

The problem of determining the discharge rates of gases from pressurized vessels through pressure relief devices was dealt with comprehensively. First, starting from basic fluid flow equations, detailed modeling procedures were presented for isentropic nozzle flows and frictional flows in a pipe, respectively. Meanwhile, physical explanations were given to choking phenomena in terms of the acoustic velocity, elucidating the widespread use of Mach numbers in gas flow models. Frictional flows in a pipe were classified into adiabatic, isothermal, and general flows according to the heat transfer situation around the pipe, but the adiabatic flow model was recommended suitable for gas discharge through pressure relief devices. Next, for the isentropic nozzle flow followed by adiabatic frictional flow in the pipe, two equations were established for two unknowns that consist of the Mach numbers at the inlet and outlet of the pipe, respectively. The relationship among the ratio of downstream reservoir pressure to upstream pressure, mass flux, and total frictional loss coefficient was shown in various forms of MATLAB 2-D plot, 3-D surface plot and contour plot. Then, the profiles of gas properties and velocity in the pipe section were traced. A method to quantify the relationship among the pressure head, velocity head, and total friction loss was presented, and was used in inferring that the rapid increase in gas velocity in the region approaching the choked flow at the pipe outlet is attributed to the conversion of internal energy to kinetic energy. Finally, the Levenspiel chart reproduced in this work was compared with the Lapple chart used in API 521 Standatd.

Recently, office workers are increasingly aware of the right to disconnect because of the pressure from strong connections with Internet messengers. In this study, we examined the reason why the perception of the right to disconnect increases and how to deal with it. This research model is that smart working and psychological attachment from work affect right to disconnect, and that open communication and gender moderate the intensity of these effects. To verify this research model, survey questionnaires were distributed to workers in smart working environments, and 400 data were collected and analyzed using Smart-PLS. As results of data analysis, it was verified that smart working and psychological attachment from work had a significant influence on right to disconnect, that open communication group had a lesser effect of psychological attachment from work on right to disconnect than closed communication group, and that women had a lesser effect of psychological attachment from work on right to disconnect than men. Organizations need to maintain a desirable level of right to disconnect in order to improve the quality of working life. But, if it is impossible, They need to change the way of communication more openly so as to absorb the burden of strong connection by Internet. And they need to perform task assignment or stress relief policy reflecting gender characteristics.

Background: The present study aims to investigate job stressors and stress relievers for Korean emotional laborers, specifically focusing on the effects of work conditions and emotional labor properties. Emotional laborers are asked to hide or distort their real emotions in their interaction with clients. They are exposed to high levels of stress in the emotional labor process, which leads to serious mental health risks including burnout, depression, and even suicide impulse. Exploring job stressors and relieving factors would be the first step in seeking alternatives to protect emotional laborers from those mental health risks. Methods: Using the third wave data of Korean Working Conditions Survey, logistic regression analysis was conducted for two purposes: to examine the relations of emotional labor and stress, and to find out job stressors and relievers for emotional laborers. Results: The chances of stress arousal are 3.5 times higher for emotional laborers; emotional laborers experience double risk-burden for stress arousal. In addition to general job stressors, emotional laborers need to bear burdens related to emotional labor properties. The effect of social support at the workplace is not significant for stress relief, unlike common assumptions, whereas subjective satisfaction (wage satisfaction and work-life balance) is proven to have relieving effects on emotional laborers' job stress. Conclusion: From the results, the importance of a balanced understanding of emotional labor for establishing effective policies for emotional laborer protection is stressed.
