A study has been conducted on developing questionnaires to serve as on site diagnostic tools for the early detection of neuropsychiatric impairment among workers chronically exposed to low-level organic solvents. Two drafts of tentative questionnaires have been developed as follows; several question items were selected from questionnaires which were administered to workers exposed to organic solvents in previous studios and were grouped into each symptom category based on the presence of its association using Guttman scaling method, then these selected items were reviewed by neuropsychiatry specialists. The final draft of the questionnaire (total symptom score=36) was developed by selecting 33 question items which had more than a 0.88 Guttman coefficient of reproducibility in each symptom category from a pilot study in which these tentative questionnaires were administered to workers manufacturing soles. Three plants using organic solvents and one plant never using organic solvents as a control group were selected to test the reliability and validity of the developed questionnaires. The major organic solvent in the workplace environment detected by a personal air sampler and GC/MSD nab toluene. The concentration of toluene in air from the department using organic solvent was statistically different from that of the department never using organic solvent. The concentration of toluene from almost all of the workplace did not exceed the allowable level. There was no statistically significant difference between the concentration of urinary hippuric acid from the workers of the department using organic solvent and that of the department never using it. Total symptom score of the plant never using organic solvents was 9.8 and those of the three plants using organic solvents were 15.6, 14.7, and 13,7 respectively. In order to evaluate the validity of the questionnaires, the workers from two different departments of the plant in which usage of organic solvents are totally dofferemt were compared. The total symptom score was 17.8 for workers of the department using organic solvent and 13.5 for the department never using organic solvent and scores of each symptom group between exposure and non-exposure group also showed statistically significant difference. The finding that total symptom score of the exposure group increased as the duration of employment increased indirectly suggests the usefulness of the developed questionnaire to assess the health effects of chronic exposure to organic solvents. The correlation coefficient, which was calculated to evaluate the test-retest reliability, was 0.581 (p=0.001). The coefficient of Crohnbach which reflects the internal consistency of the questionnaire was 0.91. In conclusion, the reliabilty of the questionnaire was well maintained over the time lapse between the two administrations of the questionnaire and despite the seasonal difference.

Purpose: This study aimed to assess the prevalence of asthma, allergic rhinitis, and atopic dermatitis in elementary school students according to the body mass index. Methods: This study was conducted as cross-sectional descriptive research using a structured questionnaire. Data were collected from 6,398 students at 15 elementary schools located in Y City in Korea. The cross-sectional survey used the Korean version of International Study of Asthma and Allergies in Childhood questionnaire. Logistic regression analysis was performed to estimate the odds ratios of body mass index. Results: The symptom prevalence of asthma, allergic rhinitis, and atopic dermatitis in the last 12 months was 12.4%, 49.5%, and 24.5%, respectively. The symptom prevalence of asthma was significantly higher in the obesity group. The number of those without any asthma symptom in lifetime was significantly smaller in the overweight (OR=0.70, p=.004) and obesity (OR=0.57, p=.005) groups than in the healthy weight group. Conclusion: These results suggest that asthma, allergic rhinitis, and atopic dermatitis prevention programs for elementary school students should include weight control intervention.

Background: The aim of this study was to describe the characteristics of male spouse caregivers of breast cancer patients in China, assess their quality of life (QOL), and investigate the influencing factors. Materials and Methods: A total of 243 breast cancer patient-spouse caregiver dyads were recruited from four hospitals in Shanxi and Anhui province of China. A cross-sectional design was applied to collect data and the Chinese version of the Medical Outcomes Study 36-item Short Form (SF-36) was used to measure caregivers' QOL, and the Chinese version of M.D. Anderson Symptom Inventory (MDASI-C) was applied to measure patient symptom severity and interference. Pearson's correlation was used to examine the correlations between caregiver burden and QOL. The multiple regression analysis was used to determine the most predictive factors influencing QOL. Results: The scores of all SF-36 scales were above 50.0, which were much lower than that of general mainland Chinese males. Mental QOL was significantly worse than physical QOL. Spouses demographic characteristics, caregiving-related variables and patient symptoms were related to spouse QOL. Caregiver burden has a negative relationship with QOL. Conclusions: A decrease in life events and patient symptoms, as well as increase in spouse sleeping time and family income, ought to improve QOL.

Objective : The sensation of dysphagia, heartburn, globus hystericus, and functional dyspepsia are common symptoms of the functional upper gut disorders. This study was designed to investigate quantity of perceived stress, depression, and anxiety in the patients with functional upper gut symptoms whose esopahgeal manometry(EM) and gatroesophageal reflux (GERT) test were normal. Methods : A total of 38 patients who complained of the symptoms had been tested with 24-hour ambulatory EM and conventional GERT in our gastrointestinal clinic. Thirty patients whose tests had been normal(patients group) were assessed with Symptom Checklist-90-Revision(SCL-90-R), Beck Depression Inventory(BDI), and Spielberger Stait-Trait Anxiety Inventory(STAI) and compared with 30 patients(control group) without functional upper gut symtpoms in the hepatobiliary clinic. The two groups were also assessed by quantity of perceived stress during the last year through self-report. Results: 1) These patients tended to be predominently female, older, and possessed a lower education than control group. 79% of 38 patients who had been tested were normal. 2) Compared to the control group, the patients had significantly higher mean scores on four subscales(somatization, depression, anxiety, and positive symptom distress index). 3) The patient group had significantly more perceived stress than the control group. 4) The patients group had significantly higher levels of depression than the control gorup, but there was not any significant difference in the STAI. 5) There were significant positive correlations between the BDI score and the STAI-trait, the STAI-stait and the STAI-trait, the quantity of perceived stress and the STAI-trait. Conlusion : The patients with functional upper gut symptoms displayed more, psychological distress, sornatization, anxiety, and deperssion. Among them, patients had higer depression than control group. Functional upper gut symtoms could be more appropriately viewed as somatic symptoms of depression. These findings suggest that such patients need to have psychiatric intervention and treatment.

This study was designed to investigate the effects of an aquatic exercise program on the shoulder joint function. physical symptom. quality of life and stress among the patients who received modified radical mastectomy between 6 to 12 months prior to their visits. The subjects were 31 women aged between 40 and 60 who visited the out-patient department at Kang Nam St. Mary's Hospital for follow-up care. and were not under the treatment of intravenous cancer chemotherapy or radiation therapy. and had no complications. Twelve of them were assigned to the control group. while nineteen subjects to the experimental group. The aquatic exercise program was developed by the author with the assistance of exercise specialists. The program includes warming uP. aerobic and cooling down exercises in water. The aquatic exercise program for the experimental group was carried out 3 times a week with 60 minutes in each time for 8 weeks from September 20th to November 15th. 1995 in a regular swimming pool in Seoul. Changes in the range of motion of the shoulder joint. muscle strength. physical symptom. quality of life. and stress were examined after the completion of treatment. The data were collected through isokinetic muscle strength evaluation and questionnaire survey before and after the treatment. Paired and unpaired t-test were adopted to analyze the data. The results were as follows ; 1. The increment in the range of motion of the shoulder joint in the experimental group after the exercise was significantly greater than those in the control group. 2. The peak torque of shoulder girdle muscles increased significantly after the exercise in the experimental group only. 3. The physical symptom score decreased significantly after the exercise in the experimental group only. 4. The experimental group revealed significantly higher level of quality of life and lower level of stress after the exercise compared with those before the exercise. whereas the control group showed no significant changes in those levels. These findings may indicate that the aquatic exercise program is effective in increasing the range of motion of the shoulder joint and muscle strength and quality of life. and also effective in decreasing physical symptoms. and the level of stress in postmastectomy patients. Accordingly. the acquatic exercise program' can be adopted as an effective nursing intervention for postmastectomy rehabilitation.

This study was designed to identify the relationships of role-conflict and role-overload, coping strategies, and stress response of clerical workers. The subjects were 115 clerical workers from two company. The instruments were the role-conflict and role-overload scale developed by Lee(1989), coping scale developed by Latack(1986), and the stress response scale developed by Chang(1993). Analysis of data was done by descriptive statistics, Cronbach's $\alpha$, Pearson correlation coefficietnt, ANOVA. The results of this study were summarized as follows ; 1. The average score for the level of stress response was $83.6({\pm}9.1)$. The high risk stress group was 86.1% of the clerical workers, the latent stress group members was 13.9%, and healthy group was 0%. The overall stress level was very high. 2. Considering the coping strategies by sociodemographic factors, the use of control coping strategies showed significant differences by work-time. The use of symptom management coping strategies showed significant differences by sex, age, married status, year of career, pay, and type of work. The organizational coping strategies showed significant differences by year of education and type of work. 3. The clerical workers who had worked below 44 hours per week complained significantly lower stress response(F=4.942, p<.05). 4. Above 65% of all respondents answered that they needed all of organizational level coping strategies. 5. The role-confilct positively related to escape and organizational level coping strategies(r=.562, r=.495, p<.05). The role-overload didn't related to individual level coping strategies, but positively related to organizational level coping strategies(r=.320, p<.05). 6. The control coping strategies and the escape coping strategies positively related to symptom management, organizational level coping strategies(r=.409, r=.324, r=.316, r=.339, p<.05). 7. The relationship between role-related stress and stress response revealed positive correlation(r=.482, r=.431, p<.05), and the relationship between stress response and control, symptom management coping strategies revealed negative cor-relation(r=-.3204, r=-.3146, p<.05). In conclusion, this study revealed that relationship of role related stress, coping strategies, stress response was statistically significant. The result of this study support that coping strategies vary across situation of stress. Based on survey results, future studies should consider coping strategies in specific stress situation and concept of symptom management coping strategy. Also organizational or training interventions could be developed and initiate to help to increase the use of adaptive coping strategies in light of individual and situational differences.
