This study was carried out to investigate psychiatric stress symptoms and stress- inducing factors, such as role overload, work demand, work procedure and so forth in korean dental laboratory technicians. Questionnaires were mailed to randomly selected 1000 dental technicians who were systematically selected. Among them, 786 dental technicians completed the questionnaires and returned them. Validity test and reliability test on the questionnaires were done prior to the main survey, using the SCL-90-R as a standard. Stress-inducing factors were identified with a multiple regression analysis on the continuous variables. To investigate stress-inducing factors on stress symptoms, analysis on distribution of characteristics was performed, and then correlation analysis and multiple regression analysis was carried out. The results of the study were as follows: According to multiple regression analysis, there was a statistical correlation between stress symptoms and role overload, work procedure, occupation conflict, interpersonal relationship, social support, personality traits in stress symptom(GSID). The stress symptoms in korean dental laboratory technicians seemed to be mostly job related ones, and considering the results obtained from the study, it is suggested that reducing work load and proper health promotion programs for dental technicians be necessary.

Objectives : This study aimed to examine the effect of biofeedback treatment on the clinical symptoms and stress responses in chronic headache patients. Methods : We recruited 18 chronic headache patients who were treated with 8 sessions of biofeedback treatment and 18 age and sex-matched control headache patients. All subjects consisted of patients with chronic tension headache and migraine hea-dache. Stress responses were measured using Symptoms of stress (SOS) inventory and all subjects performed Beck depression inventory (BDI), Spielberger state anxiety inventory (STAIS), and visual analogue scale (VAS). Biofeedback physiological vaiiables including frontal and forearm EMG, electrodermal response (EDR) and skin temperature at pre-and post-treatment were also measured in all subjects. Results : Compared with control patients, patients on biofeedback treatment showed significant reduction in scores of STAIS(t=3.705,P<.001),andVAS (t=3.392, p=.001) as well as SOS subscales ; peripheral manifestations (t= 1.788, P=.042), habitual pattems (t=2.008, P=.027), depression (t=2.081, P=.023), anxiety (t= 1.990, P=.028), and total score (t=2.045, p=.025). There was a significant increase of skin temperature (t= -1.835, P=.038) only in the biofeedback treatment group. Conclusion : These results suggest that biofeedback treatment may be effective in relieving chronic headache by reducing psychological and physiological stress responses.

Conflicts between individuals are quite natural and they can act as an positive contributing factor not only to the development of an individual but also to the organization to which one belongs. But too much conflicts will always induce dissatisfaction and stresses, which will be destructive and harmful to all of them, and that is why we are always tying to seek(find) out the causes for the origination of conflicts and remedies to cope with them effectively. The present study, as the first one in a series of studies which our researchers contemplate executing, was designed to develop a measure of job satisfaction for dental laboratory technicians. One job satisfaction measure and two job satisfaction related measures, one for faithfulness for the job and the other for environmental characteristics of dental laboratory were newly developed. The newly developed measures were comprised of a total of 38 items, which were each 12 items for job satisfaction and faithfulness for the job and 14 items for environmental characteristics of dental laboratory With the aid of factor analysis for principal components and categorization of items by panel of professionals, items of each measure were grouped into 2-4 subscales. Contribution to internal consistency was the fina) criterion for an item's inclusion in a subscale. Internal consistency reliability of each item was attested through the statistical analysis on the data obtained from 55 structured questionnaires. Reliability of internal consistency of subscales in each measure of job satisfaction and faithfulness for the job ranged from 0.74 to 0.79 and 0.90-0.91 respectively. The result from this research came to draw the following conclusions. 1. Validity and internal consistency reliability of all the items of each measure was attested. 2. The newly developed measure of job satisfaction was found to be appropriate for (measuring the degree of job satisfaction of) dental technicians, as well as for (other) dental office personnels.

This study prepared a basic framework for the development and improvement of Korean Dental Technicians' Licensing Examination, based on actual test questions. A peer review was conducted to ensure relevance to current practices in dental technology. For the statistical analysis, 1000 dental laboratory technicians were selected; specialists in dental laboratory technology (laboratory owners, educators, etc.) were involved in creating valid and reliable questions. Results indicated that examination subjects should be divided into three categories: basic dental laboratory theory, dental laboratory specialties, and a practical examination. To ensure relevance to current practice, there should be less emphasis on basic dental laboratory theory, including health-related laws, and more emphasis on dental laboratory specialties. Introduction to dental anatomy should be separated from oral anatomy and tooth morphology; and fixed prosthodontics should be separated from crown and bridge technology and dental ceramics technology. Removable orthodontic appliance technology should be renamed 'orthodontic laboratory technology'. There should be less questions related to health related law, oral anatomy, dental hygiene, dental materials science and inlay, while the distribution ratio of questions related to tooth morphology should be maintained. There should be a decrease in the distribution ratio of questions related to crown and bridge technology, dental ceramics technology, complete dentures and removable partial dentures technology, and orthodontic laboratory technology. In the practical examination, the current multiple choice test should be replaced with tooth carving using wax or plaster. In dental laboratory specialties, subjects related to contemporary dental laboratory technology should be included in the test items.

This study was carried out to investigate subjective respiratory symptoms and their attributable factors in Korean dental laboratory technicians. A questionnaire was mailed to randomly selected 1,900 dental laboratory technicians. Among them, 1,344 dental technicians completed the questionnaires and returmned them. Validity and reliability tests on the questionnaires were carried out before the main survey. To investigate risk factors on respiratory subjective symptoms, we performed analysis on distribution of characteristics, and then investigated univariate analysis and multiple logistic regression analysis. The prevalence rate of wheezing, cough and phlegm, and dyspnea was 4.8%, 33.9%, 54.9%, respectively. Statistically significant factors inducing subjective respiratory symptoms by multiple logistic regression analysis were sex, smoking, exercise, health examination, work hours a day, investment gas, investment dust, metal fume, resin vapor, and asbestos dust. Considering the results above, it seems that most subjective respiratory symptoms are related with health habits and occupational environmental-related factors. The result, consideration in mind, suggest that health promotion programs for smoking cessation, regular health examination, and physical exercise in health habit, and improvement on casting and resin work in dental technological environment be necessary.

Interleukin (IL)-20, a proinflammatory cytokine of the IL-10 family, is involved in acute and chronic renal failure. The aim of this study was to elucidate the role of IL-20 during diabetic nephropathy development. We found that IL-20 and its receptor IL-20R1 were upregulated in the kidneys of mice and rats with STZ-induced diabetes. In vitro, IL-20 induced MMP-9, MCP-1, TGF-β1 and VEGF expression in podocytes. IL-20 was upregulated by hydrogen peroxide, high-dose glucose and TGF-β1. In addition, IL-20 induced apoptosis in podocytes by activating caspase-8. In STZ-induced early diabetic nephropathy, IL-20R1-deficient mice had lower blood glucose and serum BUN levels and a smaller glomerular area than did wild-type controls. Anti-IL-20 monoclonal antibody (7E) treatment reduced blood glucose and the glomerular area and improved renal functions in mice in the early stage of STZ-induced diabetic nephropathy. ELISA showed that the serum IL-20 level was higher in patients with diabetes mellitus than in healthy controls. The findings of this study suggest that IL-20 induces cell apoptosis of podocytes and plays a role in the pathogenesis of early diabetic nephropathy.
