스트레스 정도를 측정하기 위한 다양한 도구들이 많이 사용되고 있다. 스트레스 측정에는 심리측정과 생체측정이 있다. 어느 한쪽만을 고려하였을 경우 주관적이거나 객관적 결여가 발생한다. 그 문제점을 보완하기 위해 두 측정을 혼합한 새로운 스트레스 지수가 필요하다. 개인적 특성에 따라 측정 결과도 다양하게 나타나지만, 현재 사용되고 있는 측정도구를 바탕으로 한 일반적인 경우를 고려하여 연구하였다. 심리와 생체 측정 도구를 통해서 얻어지는 지수를 이용하여 통합적인 스트레스 지수를 얻는다. 그래서 임의로 4가지의 스트레스 측정도구를 사용한다. 각 측정도구에서 나온 결과에 대한 멀티지수가 나타나는데, 그 지수들을 각각 좌표평면에 나타내어 스트레스에 대한 균형성과 편향성을 분석하고 진단한다.

We compared the spatial distribution of several heat stress indices (the Wet-Bulb Globe Temperature(WBGT) index, Environmental Stress Index (ESI), and Modified Discomfort Index(MDI)) for the heat wave of June 6~August 26, 2016, in Daegu. We calculated the heat stress indices using data from the high density urban climate observation network in Daegu. The observation system was established in February. 2013. We used data from a total of 38 air temperature observation points (23 thermometers and 18 automatic weather stations). The values of the heat stress indices indicated that the danger level was very high from 0900-2000h in downtown Daegu. The daily maximum value of the WBGT was greater than or equal to $35^{\circ}C$. The differences in the heat stress indices from downtown and rural areas were higher in the daytime than at nighttime. The maximum difference was about 4 before and after 1400h, and the time variations of the heat stress indices corresponded well. Thus, we were able to confirm that the ESI and MDI can be substituted with the WBGT index.

All of us has an experience of using the word 'stress'. During the life, we are influenced with various physical and spiritual pressure, complication, discouragement and shortage. That much, stress exists everywhere and everytime around us. It is not easy to examine how much stress you are getting. You can examine only through the health institutions. The examining method is constituted with the psychological method and physiological method, but these methods have the low accuracy about stress index because of disproportion of subjectivity, objectivity and scientific. Consequently, this thesis suggests the algorithms of processing index to help easing stress which is able to examine personally and indexing with the mixing of results of psychological and physiological methods.

본 연구는 고등학생의 구강 악습관과 스트레스가 턱관절 장애에 미치는 영향을 분석하고자 울산지역 고등학교에 재학 중인 학생 중에서 연구 참여에 동의한 339명을 대상으로 구조화된 설문지를 이용하여 시행되었다. 자료 분석은 SPSS Statistics ver 18.0 for windows 프로그램을 이용하여 t-test, one-way ANOVA, 상관분석, 회귀분석을 실시하였다. 연구 결과, 턱관절 장애지수는 구강 악습관 지수, 학교생활 스트레스 지수, 가정생활 스트레스 지수, 대인관계 스트레스 지수, 자아 영역 스트레스 지수와 정적인 상관관계가 있었다(p≤0.01). 구강 악습관 및 각종 스트레스가 턱관절 장애에 미치는 영향을 분석하기 위하여 단계선택형 다중회귀분석을 실시한 결과, 구강 악습관 지수가 턱관절 장애지수에 가장 많은 영향을 미치고 있었고 자아 영역에서 높은 스트레스를 나타내는 학생일수록 턱관절 장애지수가 높았으며 이는 유의한 차이가 있는 것으로 나타났다(p≤0.01). 즉, 구강 악습관이 지속되고 스트레스에 적절하게 대처하지 못하는 학생일수록 성인이 되었을 때 턱관절 장애를 경험하는 것으로 예측할 수 있었다. 이는 Y(턱관절 장애지수)=2.563+.550X₁(구강악습관지수)+.134X₂(자아영역 스트레스지수) 의 회귀식으로 나타났다. 따라서 청소년기에 구강 악습관과 스트레스가 성인으로 이어지는 턱관절 장애의 잠재적인 원인이 될 수 있음을 인식하고 적극적으로 구강 악습관을 개선하고 스트레스에 적절하게 대처할 수 있는 방안이 필요하다고 본다.

In the perspective of industrial health management, it is important for the employee to decrease their job stress, to improve their productivity and quality of labor. In this study, the job stress, and it's influence on PWI(Psychosocial Wellbeing Index) were investigated by the questionnaire survey of 138 industrial workers who had studied assistive technology in college. The contents of questionnaire consist of the demographic characteristics, job-related characteristics, job stress and psycho-social stress. We evaluated job stress by KOSS-SF(Korean Occupational Stress Scale-Sort Form) and psychosocial stress by PWI-SF(Psychosocial Well-being Index-Short Form). To analyze the results, we evaluated the exposure level of KOSS and PWI by demographic characteristics and job-related characteristics using significance tests. Also, we estimated the relationship among demographic characteristics, job-related characteristics, job stress and psychosocial stress, using correlation analysis. As a results, all workers were found to be in a group under the high risky stress. It showed that the scale index of female's job non-autonomy and pwi were much larger than those of male's. Therefore, to guarantee job autonomy of female workers should be more emphasized, to improve their working environment. Job type had significant relationships with many job stress category; physical environment, job demand, job instability and organization culture. Regarding pwi, the scale index of the workers who is in charge of the civil service such as contacting the disabled and the aged in person, were much larger than that of the other workers. Accordingly, the job stress management program including physical environment, job demand, job instability and organization culture, should be suggested, to decrease the stress of the workers in charge of the disabled and the elders service. The strongest predictors of pwi was organization system through maximum positive relations between organization system and pwi. Therefore, it indicates that improvement of organization system such as a fair merit rating, a manpower supply, demand plan and department cooperation is urgently needed to reduce pwi.

South Korea will soon be a super-aged society, as more than 20.6% of its population will be 65 years and older by 2025. As of 2022, 17.5% of the total population in South Korea is 65 years and older, which exceeds the set threshold for an aged society, where more than 14% of the population is 65 years and older. The proportion of older subway construction workers has increased. Aging workers and their work stress negatively impact their workability. A previous study demonstrated that the stress index measured using the uBioMacpa measurement device (Macpa stress index) had a significant correlation with work stress in South Korea. The device tests vascular health and measures stress levels via Macpa signal analysis. In this study, the pulse waves of subway construction workers were measured using uBioMacpa to identify their stress levels. The stress levels were analyzed by age, years of service, job position, employment type, and work type. Herein, these statistics could not be easily represented by a normal distribution; therefore, the Kruskal-Wallis test, a nonparametric statistical method, was used for the analysis of data. The results showed that age, job position, employment type, and working type affected the Macpa stress index and the stress levels of workers increased with age. In terms of job position, technical engineers were more stressed than other workers because of their poor working environment. In terms of employment type, daily-wage workers were more stressed than other workers. In terms of working type, tunneling, waterproofing, and construction scored the highest Macpa stress indexes without any significant difference, whereas earthworks scored the lowest. Based on the analysis of Macpa stress index, safety and health management plans were proposed to reduce the stress levels of workers. Moreover, a manual for efficient stress management must be developed for subway construction workers.

The Ergonomic Workload Stress Index (EWSI) was developed to predict the existence and level of the ergonomic workload stress in the workplace. To determine the validity of model, the values of the EWSI and two other similar techniques, Job Severity Index (JSI) and Physical Work Stress Index (PWSI) were evaluated in two actual industrial environments. The results from the validation study provide further substantial evidence that two techniques, JSI and PWSI, which have similar objective considerations, are significantly associated with the value of the EWSI among the employees participating in the experimentation.

Objectives : This study investigated the relationship between drinking, smoking and stress of workers by analyzing heart rate variability. The subjects were workers in the automobile manufacturing industry. Methods : The subjects consisted of 21,239 and 19,999 industrial workers who had received health examination by Korean oriental medicine and submitted questionnaires about drinking history and smoking history, during 8 months from April to November. The subjects were categorized into drinking history and smoking history. The heart rate variability was measured for five minute at rest using SA-3000P (Medicore) and reported stress severity as stress index, stress resistance and fatigue. We analyzed the relationship between drinking, smoking and stress into frequencies, $x^2$-test using the SPSS Ver. 12.0. Results : Regarding the relationship between drinking and stress index orstress resistance, there was no statistically significant difference, but regarding the relationship between drinking and fatigue, the drinker group had a significantly higher level of fatigue than the non-drinker group. There was a statistically significant difference in stress index, stress resistance and fatigue between the current-smoker group and others. Stress resistance of the current-smoker group had lower levels than the non-smoker group or ex-smokers. On the other hand, stress index and fatigue of the current-smoker group had higher levels than the non-smoker group or ex-smokers. Conclusions : The above results revealed that drinking and smoking could put workers under a lot of stress. Smoking workers were especially apt to be under stress and had difficulty in alleviating stress.
