This study was designed to analyze the results of stress index by heart rate variability test. The subjects were workers in the automobile manufacturing industry. The subjects consisted of 23,767 workers who had answered about questionnaires of a job position, age, smoking, drinking, exercise state and sex. The stress index(SI) and stress resistance(SR) were examined by SA3000P. We analyzed the differences of SI and SR according to job positions, ages, the state of smoking, drinking, exercise and sex by T-test or ANOVA with SPSS ver. 17.0. Regarding the differences of SI among job positions, the SI was highest in sales positions. Among ages, the SI was highest in 30s. In smoking, the SI was lower in non-smoking group. In drinking, there was no significant differences in SI. In exercise, the SI was lower in exercise group. In sex, there was no significant difference. The case of SR, SR was lowest in sales positions. Among ages, the SR was lowest in 40s. In smoking, the SR was lower in smoking group. In drinking, there was no significant differences in SR. In exercise, there was no significant difference. In sex, the SR was lowest in male. According to these results, we should establish the methods of controlling stress from the perspective of Korean traditional medicine.

There has been increased interest in the health effects of the Environmental Tobacco Smoke(ETS) as a confirmed human carcinogen. It has been known to be extremely difficult to make an accurate assessment of exposure to ETS since it is consisted of a variety of components and there are a number of labile chemicals. Therefore, it is necessary to obtain, to interpretate and to provide the data of quantitative exposure assessment to ETS in the field of environmental health. The purpose of this research is to evaluate the concentration of ETS using VOC in indoor office environments. The correlations and concentrations of benzene, RSP, 3-EP, nicotine that are indicators for ETS were investigate with smoking density, air change per hour(ventilation rate). Air samples were taken in smoking room(7 sites), smoking allowed office (3 sites), corridor outside smoking room(7 sites), non-smoking office (9 sites). The concentrations of benzene showed significant difference according to category of indoor office environments. The geometric mean concentration of benzene were 23.56 ${\mu}{\textrm}{m}$/㎥(range 4.80~192.90 ${\mu}{\textrm}{m}$/㎥) in smoking rooms. 6.16 ${\mu}{\textrm}{m}$/㎥ in smoking allowed offices, 1.32 ${\mu}{\textrm}{m}$/㎥ in the non-smoking offices respectively. The ratios of the concentration of benzene between outdoor air and smoking room, smoking allowed office, and non-smoking indicators concentrations, SD, and SI were 0.82(benzene and nicotine). 0.76(benzene and RSP), 0.60(benzene and SD), 0.76(benzene and SI). It is proposed that benzene is a good indicator for ETS.

The purpose of this study was to investigate the dietary habits of smokers and non-smokers among a few male university students residing in Changwon-si and factors that affect their smoking behavior. A self-administered questionnaire was conducted for a duration of one month in June 2015 (n=367). The results of this study showed that the breakfast skipping rate of the smoking group was significantly higher compared to the non-smoking group (p<0.001), and the smoking rate was significantly higher among those with more serious smoking problems (p<0.001). Compared to the non-smoking group, the smoking group showed significantly higher BMI (body mass index) (p<0.05) and demonstrated significant drinking habit of more liquid type yogurt among milk and dairy products and significantly more coffee mixes among fat, oils, and sugars (p<0.05). The results of multiple regression analysis showed the necessity to prepare smoking systems in school (t=-2.87, p<0.05), encumbrances to studies due to smoking (t=-3.59, p<0.001), and variables that affect smoking such as the number of close friends who smoke (t=4.17, p<0.001), BMI (t=3.08, p<0.05), and the level of problematic drinking (t=3.67, p<0.001). The results of this study suggest factors that must be considered in establishing smoking prevention education programs, anti-smoking policies, and strategies for university students.

This study aimed to identify the effects of lifestyle on Mibyeong, and provide basic data for health promotion activities for management of Mibyeong. A total of 405 data were analyzed for Daejeon University employees from July, 2015 to Jan, 2016. In this study, we collected the data about sex, age, BMI, dietary habit, physical activity, smoking, drinking, and Mibyeong index. There was a difference between Mibyeong groups according to irregular eating, eating of night snack, and smoking for men, while overeating, irregular eating, and physical activity for women. Logistics regression analysis, adjusting for sex and age, was used to estimate related factors of Mibyeong. Compared to the healthy group, Mibyeong 2 group tended to overeat 4 times a week with odds ratio of 3.52, eat irregularly with odds ratio of 2.67, lack of physical activity with odds ratio of 3.30, and to smoke with odds ratio of 3.07. This study suggests that lifestyle, particularly dietary habit, physical activities, and smoking, might be significantly associated with Mibyeong. Good lifestyle could help prevent Mibyeong.

In order to evaluate the physical and mental health status of airline flight attendants, 136 airline flight attendants were given a general health questionnaire (Todai Health Index), and the prevalence of their subjective complaints was measured. Collected data were classified according to age distribution, length of employment, service area, smoking status, job satisfaction, gender, and marital status. The results obtained were summarized as follows: 1 The scores of health complaints of physical items were higher in the oldest group $(age 50\~60)$ than in younger groups. The THI eye and skin symptom scores were significantly higher for the oldest groups than for the younger groups. 2. The health complaints scores of physical items were higher in the long-length employment group (more than 5 years), whereas most scores of mental items were higher in the short- length employment group (less than 2 years). The THI mouth and anus scores for the long-length employment group were significantly higher than for groups of workers who had been employed for a shorter time. 3. THI scores were higher for domestic airline crews, dissatisfied workers and females. 4. The irregular life THI score was significantly higher among domestic crews than international crews. 5. The impulsiveness and depression scores were significantly higher in the dissatisfaction group. 6. The female group showed higher scores in the multiple subjective symptoms, mental irritability, depression, and irregular life categories. 7, The THI scores of the mouth, anus and nervousness were significantly higher for the married group than for the unmarried group. In summary, this study shows that the health complaints scores of physical and mental symptoms tended to be higher among the aged group, domestic airline crews, the dissatisfaction group, and females. These results can be used for improving the psychosomatic health status and working environments of flight attendants.

Objective : Intraoperative neurophysiological monitoring (IONM) has been widely used during spine surgery to reduce or prevent neurologic deficits, however, its application to the surgical management for cervical myelopathy remains controversial. This study aimed to assess the success rate of IONM in patients with cervical myelopathy and to investigate the factors associated with successful baseline monitoring and the effect of increasing the stimulation intensity by focusing on motor evoked potentials (MEPs). Methods : The data of 88 patients who underwent surgery for cervical myelopathy with IONM between January 2016 and June 2018 were retrospectively reviewed. The success rate of baseline MEP monitoring at the initial stimulation of 400 V was investigated. In unmonitorable cases, the stimulation intensity was increased to 999 V, and the success rate final MEP monitoring was reinvestigated. In addition, factors related to the success rate of baseline MEP monitoring were investigated using independent t-test, Wilcoxon rank-sum test, chi-squared test, and Fisher's exact probability test for statistical analysis. The factors included age, sex, body mass index, diabetes mellitus, smoking history, symptom duration, Torg-Pavlov ratio, space available for the cord (SAC), cord compression ratio (CCR), intramedullary increased signal intensity (SI) on magnetic resonance imaging, SI length, SI ratio, the Medical Research Council (MRC) grade, the preoperative modified Nurick grade and Japanese Orthopedic Association (JOA) score. Results : The overall success rate for reliable MEP response was 52.3% after increasing the stimulation intensity. No complications were observed to be associated with increased intensity. The factors related to the success rate of final MEP monitoring were found to be SAC (p<0.001), CCR (p<0.001), MRC grade (p<0.001), preoperative modified Nurick grade (p<0.001), and JOA score (p<0.001). The cut-off score for successful MEP monitoring was 5.67 mm for SAC, 47.33% for the CCR, 3 points for MRC grade, 2 points for the modified Nurick grade, and 12 points for the JOA score. Conclusion : Increasing the stimulation intensity could significantly improve the success rate of baseline MEP monitoring for unmonitorable cases at the initial stimulation in cervical myelopathy. In particular, the SAC, CCR, MRC grade, preoperative Nurick grade and JOA score may be considered as the more important related factors associated with the success rate of MEP monitoring. Therefore, the degree of preoperative neurological functional deficits and the presence of spinal cord compression on imaging could be used as new detailed criteria for the application of IONM in patients with cervical myelopathy.

Purpose: To analyze the correlation between a rupture of the hypovascular zone and early single heel raising after Achilles tendon repair. Materials and Methods: From January 2012 to August 2015, 68 patients, who underwent surgical treatment for a Achilles tendon rupture using Krackow method, were analyzed retrospectively. The patients were divided into two groups according to possibility of single heel raises within 3 months postoperatively. During the periodic outpatient observations, the visual analogue scale, Achilles tendon total rupture score (ATRS), and timing capable single heel raises were evaluated. In addition, the preoperative defect size and distance between the calcaneal osteotendinous junction and the rupture site were measured by ultrasound in all cases. Results: Twenty-three patients could perform a single heel raise within 3 months after surgery (early single heel raise group), and fortyfive patients could perform a single heel raise after 3 month postoperatively. The age, gender, body mass index, smoking, and operation delay were similar in the two groups. In addition, the defect size and distance between the calcaneal osteotendinous junction and rupture site as measured by preoperative ultrasound were similar (p=0.379 and p=0.631, respectively). On the other hand, when the rupture site was divided into the hypovascular zone (4~7 cm from calcaneal osteotendinous junction) and non-hypovascular zone, the hypovascular zone rupture rate was significantly lower in the early single heel raise group (60.9%, 14/23; 91.1%, 41/45; p=0.003). In logistic regression analysis, the odds of the hypovascular zone rupture group being capable of early single heel raise were 0.189 (p=0.017). The ATRS score at 3 months and 1 year after surgery were significantly higher in the early single heel raise group (p<0.001). Conclusion: Achilles tendon rupture at the hypovascular zone is a poor prognostic factor for early single heel raise and might affect the prognosis significantly after an Achilles tendon rupture operation.
