Objectives: The purpose of this study was to assess excavator drivers in order to determine the proportion showing subjective symptoms of musculoskeletal disorders and to evaluate the association between the symptoms and characteristics of the subjects. Methods: A questionnaire survey was conducted to collect the information on participants' age, average working hours per day, duration of career (years), work-related musculoskeletal symptoms, and more. The final dataset included 141 excavator drivers. Frequency and percentage were summarized and then the associations between the characteristics of the subjects and symptoms were evaluated as odds ratios (ORs) and 95% confidence intervals (CIs) using multiple logistic regression analysis. Results: Seventy-six percent of the currently reported musculoskeletal symptoms. Those who have musculoskeletal symptoms attributed their symptoms to unstable posture at work, mental stress or vibrations. There was a significant association between symptoms of musculoskeletal disorders and career of excavator drivers (P for trend=0.04). Conclusions: The results of this study suggest that the prevalence of musculoskeletal disorders may be high among excavator drivers and warrants well-designed studies on work-related disorders among excavator drivers.

Objective: The purpose of this study was to identify factors associated with subjective memory impairment in patients with diabetes mellitus in a metropolitan city. Methods: The subjects of this study were 351 patients with diabetes mellitus aged 50 and over from five districts of Gwangju who participated in the 2018 Community Health Survey. We analyzed general characteristics, health-related behaviors and health related conditions and subjective experience of memory impairment. To find factors associated with subjective memory impairment, the chi-square test and multiple logistic regression analysis were used. Results: Of all subjects, 31.3% was reported subjective experience of memory impairment. The odds ratios (ORs; 95% confidence interval (CI)) for subjective memory impairment according to age were statistically significant at 1.9 (0.9-4.3) in patients in 60s and 2.2 (1.1-4.7) in patients in beyond 70s compared to those in 50s. The OR (95% CI) of ex-smoker compared to the non-smoker was 0.3 (0.8-0.9). The OR (95% CI) of depressive symptom compared to no depressive symptoms was 4.9 (95% CI: 1.8-13.7). Conclusion: In this study, subjective memory impairment in patients with diabets mellitus was associated with age, smoking, and depressive symptoms. Based on the results of this study, subjective memory impairment should be detected early through periodic cognitive function evaluation for elderly patients with diabetes mellitus, and a program for healthy cognitive function should be included in diabetes management program.

In order to investigate and compare the health risk factors of nurses in the operating room(OR nurse) and ward (WARD nurse), the questionnaire survey for subjective symptoms was carried out on 553 nurses(132 OR nurses and 421 WARD nurses) who were employed at seven hospital. The self-administered questionnaries were composed of low back pain, subjective fatigue symptoms, musculo-skeletal symptoms, psychological stress and reproductive function. The results were as follows : 1. In the type of working posture and working environment, there were significant difference between two groups for working posture, waist form, height of working table, satisfaction of chair, lifting & carring. 2. Job satisfaction, duration of work, height of working table, satisfaction of chair, lifting & carring were significantly associated the low back pain. 3. In the complaints of subjective fatigue symptoms, the total mean score was higher in OR nurse than WARD nurse, but there was not significant. The items that the mean score of OR nurse was significantly higher than WARD nurse were 'head feels muddled', 'apt to forget', 'feel choky'. 4. In the complaints of musculo-skeletal syrrptoms, the total mean score was higher in OR nurse than WARD nurse, but there was not significant. The item that the mean score of OR nurse was significantly higher WARD nurse was 'wrist discomfort or pain'. 5. The comparison of spontatenous abortion in married nurses who had the experience of pregnancy were significantly associated the stress risk group. 6. In all of OR and Ward nurses, the job satisfaction is associated with subjective fatigue symptoms, musculo-skeletal symptoms, and stress. In conclusion, it suggested that working posture, working environment, stress, and job satisfaction were health risk factors of nurses working in the operating room. Further prospective intervention studies should be conducted to educate right working posture, improve of working environment, decrease of stress, and increase of job satisfaction.

Purpose: To find out the relationship between the shift work, and disrupted sleep and consequent fatigue symptoms. Methods: The questionnaires were given to 345 nurses of 4 hospitals with over 400 beds in Daejeon. Results: The shift workers showed worse subjective quality of sleep than the daytime workers, and had significantly higher frequency of "cannot get to sleep within 30 minutes", "wake up in the middle of the night" and "wake up in the early morning". The shift workers had significantly higher scores of subjective symptoms of fatigue than the daytime workers, and the fatigue was found to be the mental type. The subjective symptoms of fatigue scores were significantly higher in the group who had "cannot get to sleep within 30 minutes", "wake up in the middle of the night" and "wake up in the early morning". Conclusion: The study results indicated that the shift workers had the higher level of subjective symptoms of physical fatigue as well as the worse quality of sleep than the daytime workers. It is speculated that the factors attributable to the poor quality of sleep or sleep induction disorders of nurses of hospitals could be due in major part to adaptational difficulties resulting from frequent night shifts.

전기기기의 사용이 증가함에 따라 60Hz 전력선에서 발생되는 전자기장의 인체영향에 관한 관심이 고조되고 있다. 그와 더불어 60Hz 자기장에 의해 두통, 불면증 등 정신 신경 생리학적 증상을 호소하는 사람들이 증가하고 있다. 그러나 이러한 증상이 자기장 노출에 의한 것인지 심리적 요인 때문인지에 대하여 확실한 원인규명이 되어 있지 않다. 따라서 본 연구는 자기장 노출 시 생리학적 변화(심박수, 호흡수, 심박변이도, 뇌파의 알파, 베타파), 자각증상, 자기장 인지 여부를 동시에 측정하여 복합적으로 자각 증상 원인을 분석하는 연구를 수행하였다. 60Hz 12.5uT의 자기장을 일반인 군(16명)과 EHS 군(15명)을 대상으로 실제 노출 및 가상 노출을 하였다. 그 결과 알반인 군과 EHS 군 모두 60Hz 자기장 노출여부에 따른 생리학적 변화나 자각증상의 차이가 없었다. 또한 자기장 인지 정확도에서도 EHS 군이 일반인 군보다 인지를 잘한다고 볼 수 없었다. 그러므로 EHS 유발요인은 60Hz 자기장이 아니라 다른 심리적, 환경적 요인에 의한 것으로 사료된다.

Purpose: The purpose of this study was to examine the relationship among subjective symptoms, depression, and stress coping behavior of university students. Method: The survey was carried out on a convenience sample of 298 university students. The questionnaire consisted of each scale for symptoms, depression, and stress coping behaviors. Data analysis procedure included the factor analysis for stress coping behaviors, and the correlation analysis describing a relationship among symptoms, depression, and stress coping behaviors. Result: There were significant correlations between depression and the three types of symptoms: general, psychological, and somatic symptom. Subjects using the negative-emotional-response coping and the self-control coping showed a more severe depression, and those using the problem-solvingㆍreappraisal coping and the positive-emotional-response coping showed a milder depression. Subjects using the negative-emotional-response coping complained of all 3 types of symptoms severely, and those using the positive-emotional-response coping complained of general symptoms mildly. Of five stress coping methods, the negative-emotional-response and the positive-emotional-response coping methods were related to both symptoms and depression significantly. Conclusion: This study suggests that the emotional-oriented coping method has more important role for university student’s depression and their subjective symptoms than the problem-oriented coping or social supports seeking coping. Further study needs to be conducted to help students effective coping mechanism for good mental health. Also it is necessary for university students to recognize that their symptoms are associated with depression.
