The purpose of this study was to analyze relationship between the role conflict and self-reported climacteric symptoms in the middle-aged industrial female workers. The data were collected by self-reported questionnaire from Nov. 1 to Nov. 30, 1996. The subjects were 201 women whose age, between 40 and 59 years. The analysis of data was t-test, ANOVA, $Scheff{\grave{e}}$ test, Pearson correlation coefficient analysis, Stepwise multiple regression analysis. The results were as follows : 1. 54.8% of the respondents had their climacteric symptom in middle life. 2. Age and religion affected significantly self-reported climacteric symptoms(F=4.2, P=.007 ; t=-2.1, P=0.42). 3. A comparison between two groups, with high and low rate of self-reported climacteric symptoms, indicated that for middle-aged industrial female workers when role conflict is high, climacteric symptoms is high(t=7.8, P=.000). 4. The relationship between self-reported climacteric symptoms and role conflict was positively significant(r=.5, P=.000). 5. The role conflict as a spouse affected significantly self-reported climacteric symptoms(F=52.6, P=.000). Role conflict the role as a spouse was explained 21% of self-reported climacteric symptoms. In conclusion, role conflict is the dominant factor in influencing self-reported climacteric symptoms.

Purpose: This study was designed to identify the relationship between self reported climacteric symptoms, self concept and depression in middle aged women. Method: Data were collected through self-reported questionaires which were constructed to include a climacteric symptoms, self-concept and depression of middle-aged women scale. The subjects for this study were 102 women between 40-59 years of age living in P city. The data were analyzed by descriptive statistics, t-test, ANOVA, Pearson Correlation Coefficient. Results: The results obtained from this study were as follows : 1) The relationship between self reported climacteric symptoms and self concept was statistically significant with a negative correlation (r=-0.4862, P0.001). The relationship between self reported climacteric symptoms and depression had a statistically significant positive correlation (r=0.5393, P<0.001). The Relationship between self-concept and depression had a statistically significant negative correlation (r=-0.3769, P<0.001). 2) General characteristic variables significantly related to self reported climacteric symptoms were age (F=3.13, P<0.05) and frequency of pregnancy (F=3.24, P<0.05). General characteristic variables significantly related to frequency of self-concept were age (F=3.13, P<0.05), education level (F=2.97, P<0.05) and occupation (t=1.84, P<0.05). General characteristic variables significantly related to depression were age (F=3.12, P<0.05) and number of children (t=3.59, P<0.05). 3) The obstetrical characteristic variable significantly related to self-reported climacteric symptoms was the frequency of pregnancy (t=3.24, P<0.05). Conclusion: This study shows possible implications for nursing intervention for middle-aged women's health to prevent and relieve climacteric symptoms.

Background: Assembly lines work is frequently associated to work-related upper limb musculoskeletal disorders. The related disability and absenteeism make it important to implement efficient health surveillance systems. The main objective of this study was to identify self-reported variables that can determine work-related upper limb musculoskeletal symptoms-discomfort/pain-during a 6-month follow-up. Methods: This was a prospective study with a 6-month follow-up period, performed in an assembly line. Upper limb musculoskeletal discomfort/pain was assessed through the presence of self-reported symptoms. Uni- and multivariate logistic regression analyses were used to evaluate which self-reported variables were associated to upper limb symptoms after 6 months at the present and to upper limbs symptoms in the past month. Results: Of the 200 workers at baseline, 145 replied to the survey after 6 months. For both outcomes, "having upper limb symptoms during the previous 6 months" and "education" were possible predictors. Conclusion: Our results suggest that having previous upper limb symptoms was related to its maintenance after 6 months, sustaining it as a specific determinant. It can be a hypothesis that this population had mainly workers with chronic symptoms, although our results give only limited support to self-reported indicators as determinants for upper limb symptoms. Nevertheless, the development of an efficient health surveillance system for high demanding jobs should implicate self-reported indicators, but also clinical and work conditions assessment should be accounted on the future.

Objectives : The study investigated and analyzed the relationship between health-related lifestyle and psychosomatic self-reported symptom in dental hygiene students. Methods : A self-reported questionnaire was filled out by 478 dental hygiene students in Gyeonggi-do and Gangwon-do from March 7 to June 21, 2012 by random sampling method after informed consent. Results : The health-related lifestyle showed the results as follows. Nonsmokers accounted for 89.1%. Those who never exercise accounted for 67.9% and 37.9% of the students sleep for 5-6 hours. Those who take alcohols twice per month accounted for 58.2%. The correlation between the symptoms and lifestyle included multiple subjective symptoms(I), respiratory(A), eyes and skin(B) and digestive organs(C) symptoms and smoking status(p<.01), mouth and anal(D), depression(K), nervousness(E). There existed the correlation in average sleeping time(p<.01) and impulsivess(H) and smoking status(p<.05) and lie scale(L) and regular exercise(p<.05) and aggressiveness(F) and drinking habits and irregular and life(G) and breakfast habits. The smoking habit, sleeping time, and snack intake had an influence on psychosomatic self-reported oral health-related symptoms. Conclusions : Cessation of smoking, adequate sleeping time, and reduction of snack intake can improve the oral health-related lifestyle and reduce the self-reported symptoms in the dental hygiene students.

Purpose: This study is to present substantial data for the development of practicable health related programs with which the dental technicians can enjoy better quality of life. To this end, we have surveyed the self-reported psychosomatic symptoms of the dental technicians in Korea and figured out their current health problems. Methods: Out of the random selection of the registered dental offices of Dental Technicians in Korea, 2,000 working dental technicians were asked to fill out the questionnaire from January 19 to April 30, 2009. We collected the 1,525 sheets of the questionnaire and took frequency analysis, t-test, analysis of variance and structural equation modeling using SPSS Win 12.0 and AMOS program. Results: Concerning the modes of the subjects' appealing of their psychosomatic self-symptoms, scale point of the mental health turned out 18.68, which is higher than the physical health that scored 17.28. In the case of the results from the standardized scores of the sub items, scale point of aggressiveness scored the highest(20.14), whereas that of mouth and annus scored the lowest (15.29). Additionally, the overall satisfaction rates of the health related quality of life was 67.89. Regarding the health related quality of life, self reported mental symptoms(-.736) was more influential than physical symptoms(0.29). Conclusion: The psychosomatic self reported symptoms of the dental technicians proved higher than other occupations, whereas health related quality of life was very low. Consequently, it seems vital to lessen the mental symptoms and the sub items concerned.

This study aimed to determine the feasibility of survey questionnaires for pesticide poisoning. We conducted a pilot study to develop a questionnaire for evaluating pesticide poisoning symptoms and to examine the validity of self-reported information for individual pesticides used. In December 2010 we interviewed 20 farmers with self-reported pesticide poisoning histories residing in Gyeonggi Province. For validity of pesticide information, the purchased pesticide lists from the agricultural cooperative federation were compared with individual self-reported pesticides used. Neurological symptoms were the most common among clinical symptoms related to pesticide poisoning, followed by gastrointestinal, dermal and eye symptoms. Insecticides were the main causative pesticide class for poisoning. Twenty one major symptoms were selected for screening for acute pesticide poisoning in a field study based on the pilot results and literature reviews. Substantial under-reporting was found in data on self-reported individual pesticides used (9.2%), as well as low accuracy (36%) compared with their actual purchase lists. In this pilot study, we suggest the selected symptom lists may apply to a field survey of pesticide poisoning. However, the self-reported information on individual pesticides may not be valid and alternative methods need to be developed.

Objectives: An ultra dry air environment of nearly ${\leq}2%$ RH is often required in lithium battery factories. The objective of this study is to evaluate the subjective eye, pulmonary, nose, and skin symptoms of workers exposed to ultra-low relative humidity and thionyl chloride. Methods: We recruited 274 workers using a self-reported questionnaire in March 2014. Those who worked in ultra-low relative humidity and with thionyl chloride were identified and their prevalence of symptoms was compared with that of other workers. We excluded white collar workers, researchers and other workers who were exposed to various hazard factors, and finally included 164 workers. Results: There were significant differences in the rate of self-reported eye and skin symptoms between exposure group_1 and exposure group_2. Exposure group_2 experienced more frequent eye, and skin symptoms. Multinomial logistic regression analysis for experience of dry eye symptoms and skin symptoms in exposure group_2 showed that dry eye symptoms (odds ratio [OR], 6.33, 95% confidence interval [CI], 2.19-18.24, p<0.001), and itchiness (OR, 6.45, 95% CI, 1.94-21.43, p<0.01) were the significant variables. The complaints of workers experiencing ultra-low relative humidity and thionyl chloride were high compared with other workers. Conclusion: These findings suggest that exposure to ultra-low relative humidity and thionyl chloride may be associated with more frequent eye and skin symptoms than exposure to ultra-low relative humidity alone. The current precautions to protect workers from the adverse effects of ultra-low relative humidity and thionyl chloride appear to be insufficient, indicating that additional management plans to reduce symptoms should be considered.

Purpose: This research is performed through the analysis of the dental technology students' life-style factors of their daily lives that have a close relation with health, and the self-reported symptoms which are related to psychosomatic diseases, for the production of basic data for the change of life-styles and the development of educational programmes. Methods: This research has been performed through questionnaires from the beginning of October of 2014 till the end of November through the Dental Technology students of G-do, chosen by random sampling method after informed consent, where out of the 270 papers, 258 results were used for the analysis. Results: Firstly, the results of the research was as follows: Non-smokers accounted for 61.2%, student who did not do regular physical activities accounted for 50.4%, students who had sleeping hours of 6 to 7 hours accounted for 35.7%, students who eat snacks accounted for 63.2%, students who eat breakfast once to twice a week accounted for 30.6%, students who had an average number of drinks of once to twice a week accounted for 39.9%, and students with BMI of '$18.5^{\circ}{{\neq}}22.9$' accounted for 56.2%, being the highest. Secondly, in gender, smoking (p<.001), regular physical activity (p<.001), BMI (p<.001), eat snacks (p<.05), average number of drinks (p<.05), and of the health check-up, eat breakfast (p<.05), of the year level, eat snack (p<.01), BMI (p<.01), hours of sleep (p<.05), of major satisfaction, regular physical activity (p<.01), and BMI (p<.05), and there was a significant statistical difference, but there were no significant statistical difference in religion. Thirdly, of the bodily self-reported symptoms of the correlation analysis within the life-style variables and the self-reported symptoms, multiple subjective symptoms (I), respiratory (A), eye and skin (B), and digestive organs (C) were the highest in the correlation analysis with regular physical activity (p<.01), and of mental health, impulsiveness (H), mental instability (J), and depression (K) showed highest results in correlation analysis with regular physical activity (p<.01, p<.05), lie scale (L) and irregular and life (G) with eat breakfast (p<.01), and aggressiveness (F) with BMI (p<.01), showed highest results in correlation analysis. Fourthly of the Dental technology students' bodily self-reported symptoms, life-style factors which had a statistically significant effect appeared to be regular physical activity (p<.001) and BMI (p<.05), and of the mental self-reported symptoms, causes that did not have statistically significant effect appeared to be regular physical activity (p<.05) and eat breakfast (p<.05). Conclusion: This research concludes that in order to develop correct life-style habits for health promotion and reduce self-reported symptoms related to the Dental Technology students' diseases, education for the recognition of the necessity of self health promotion must be conducted, and a education programme scheme for the Dental technology curriculum for practicing the correct life-style habits in daily life is required.

The aim of this study was to determine the association between the Body Mass Index (BMI), weight perception and depression-like symptoms in Korean middle school students. The data was obtained from the 2012 Korea Youth Risk Behavior Web-based Survey. The subjects were 37,297 students living in the community. Adjusting for covariates (sex, school year, home economics, city-type, school record, self-reported happiness, self-reported health status, suicidal thinking, smoking, alcohol consumption), the self-reported obesity (OR=1.14, 95% CI: 1.06-1.22) and self-reported underweight (OR=1.11, 95% CI: 1.03-1.20), compared to the self-reported healthy weight, were more likely to have depression-like symptoms. On the other hand, the BMI-based weight was not associated independently with depression-like symptoms. These findings suggest that weight perception is significantly associated with depression-like symptoms.
