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.

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.

This study investigated mean airborne CO concention of 15 workplaces, suspected of CO exposure and conducted self-reported questionnaire completion and indirect COHb concentration measure using Micro II Smokerlyzer to healthy 702 adult subjects from 1999 May to 1999 September in order to find a relation of CO exposure and occupational factors, socioeconomic factors, and health related behaviors and confirm the related conditions in the screening test for CO exposure. The results of this study were summarized as follows : 1. In the CO exposed and non exposed group, COHb concentrations of the smokers were 2.55±0.96% and 2.21±0.97% and that got a statistically significant difference, There were not statistically significant differences in the age and total smoking index. Passed times after the last smoking, Working time/day, and working duration were statistically significant difference (p〈0.05). 2. In the CO exposed and non exposed group, COHb concentrations of non-smoking group were 0.94±0.35% and 0.68±0.47% and that got a statistically significant difference. There were not statistically significant differences in the age and working duration but Working time/day was a statistically significant difference(p〈0.05). 3. In the CO exposed group, r-square of multiple regression of the smokers was 38.5 % and passed time after the last smoking, working time/day, and job category were statistically significant differences (p〈0.05). And r-square in the CO non-exposed group was 38.3 % and age, passed time after the last smoking, and total smoking index were statistically significant difference. 4. In the CO exposed group, r-square of multiple repression of the non-smokers was 66.3% and job category and airborne CO concentration were statistically significant differences(p〈0.05). But r-square of non-smokers in the CO non-exposed group was 1.0% and there was not a statistically significant difference(p〈0.05). 5. In the smokers of CO exposed and non exposed groups, relation of COHb concentration and passed time after the last smoking was expressed as exponential function, Y = 2.9182e-0.0083x and r-square of this function was 37.4%. Therefore it was more than 150 minutes that passed time after the last smoking was when COHb concentrations were measured as less than 1%. In conclusion, variable, that was statistically significant to COHb concentraion in the both CO exposed and non-exposed smokers, was a passed time after the last smoking. We suggest that you have to restrict the smoking of smokers at least 150 minutes in the exposed and non exposed group before COHb concentration measure in order to exclude smoking effects

Responses to chemotherapy correlate with the increased dose of chemotherapeutic agents in some cancers, e.g. breast cancer, Ewing's sarcoma, Hodgkin's disease(HD) and non-Hodgkin's lymphoma(NHL), then for the improvement of the chemotherapy responsiveness, high-dose chemotherapy(HDCT) was proposed. But, it's application was limited due to complications, especially bone marrow suppression. HDCT and succeeding autologous peripheral blood stem cell transplantation(APBSCT) was introduced to overcome this problem. This study was designed to determine the clinical pictures including clinical parameters and the responsiveness of HDCT followed by APBSCT in Hanyang University Hospital. Ten patients were enrolled. They were 8 adults (3 breast cancers, 3 multiple myelomas, 1 HD, 1 NHL) and 2 children (1 acute myelogenous leukemia (AML), 1 neuroblastoma). Mobilization chemocherapy(MCT) followed by Granulocyte Colony Stimulating Factor(G-CSF) was administered to mobilize stem cells from bone marrow to peripheral blood. The stem cells were collected by using CS-3000 and cryopreserved at -196℃ with programmed controlled rate freezer as the mixture with 10% dimethyl sulfoxide(DMSO). HDCT was administered and cryopreserved peripheral stem cells were infused on day 0 as planned. Patients' mean age was 41 years old. After induction chemotherapy three patients achieved complete response and 5 partial response. The median time for bone marrow recovery after MCT was 11.5 days for neutrophil(〉500/㎣) and 4.8 days for platelet(〉20,000/㎣). There were three cases of neutropenic fever and one case of gingivitis. After HDCT with APBSCT, one patient was converted partial response to complete response, and one patient achieved complete response after HDCT without induction chemotherapy. The median time for bone marrow recovery was 12.7 days for neutrophil(〉500/㎣) and 14.7 days for platelet(〉20,000/㎣). Eight patients developed neutropenic fever and required systemic antibiotics. Transfusion was required 1.6 pints for packed red cell and 23.4 pints for platelet concentrates. Toxicity consisted mainly of vomiting, diarrhea, and mucositis which were mild. HDCT with APBSCT can be performed safely with minimal complications. For the evaluation of the exact role of HDCT with APBSCT in malignant diseases, further studies are required as a large scale of patients and lung-term follow up.

A correlation analysis was made to understand the interaction between the growth patterns of some craniofacial skeletal components and occlusal plane inclination. 5 angular measurements(S.a. Ar.a, Go.a, UGo.a, LGo.a), 6 linear measurements(ACBL, PCBL, RH. MBL. AFH. PFH) and OP/SN. obtained from 83 cephalometric tracing records, were selected and the relationship between the occlusal plane angle and those measurements were analyzed statistically. Ramus Height(r=-0.55), Posterior Facial Height(r=-0.41), were found to be negatively related with Occlusal Plane angle, while Lower Gonial angle(r= 0.35), Saddle angle(r= 0.24) were found to be positively related with Occlusal Plane angle(p(0.05). The results obtained from the above analysis were further assessed with stepwise regression analysis, using Occlusal Plane angle as a dependant variable, and RH, LGo.a and S.a as explanatory variables. Stepwise regression analysis revealed that all the explanatory variables were found to be significant.(p<0.05) [OP/SN] = -8.74-0.33(RH)+0.23(S.a)+0.20(LGo.a). (R²=0.44). This stepwise regression analysis explains, to some extent, the relationship between the growth patterns of some craniofacial skeletal components and the occlusal plane inclination. 1. The inclination of Occlusal Plane angle is noticeably related with the growth patterns of some craniofacial skeletal components, i.e. RH, PFH, Saddle angle and Lower Gonial angle 2. In high Occlusal Plane angle, the Ram us Height tends to be shorter, and the Saddle angle and Lower Gonial angle tend to be obtuse.

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.

The relationship between Personal Attitude and Independent Variables. The first, correlation coefficient between formal education and personal attitude is r=-0.1737, F=7.71>F_(α)=6.76 The second, correlation between age and personal attitude is r=0.1214, F=3.71<F_(α(α=0.01))=6.76, F=3.71<F_(α(α=0.06))=3.89; r is not significant. The third, correlation coefficient between mass media and personal attitude is r=0.0453, F=0.509<F_(α(α=0.06))=3.89; i is not significant. The forth, correlation coefficient between training and persoral attitude is r=0.0625, F=0.969<F_(α(α=0.06))=3.89; r is not significant. The fifth, correlation coefficient between administrative supports and personal attitude is r=0.1907, F=9.35>F_(α(α=0.01))=6.76 The sixth, correlation coefficient between consciousness development and personal attitude is r=0.1454, F_(α(α=0.01))=6.76>F=5.35>F_(α(α=0.01))=3.89 7. Accordingly, independent variables are somewhat correlated to policy concern, policy perception, policy participation and policy expection, but those are not correlated to personal attitude. This means that Korean rural society is alike to the Prismatic Society of Fred. W. Riggs, which is in the changing stage from fused society (or agricultural society) to diffracted society (or industrial society). Byt the modernization which includes factors such as formal education, age, mass media, training, administrative supports and consciousness development, the consciousness of rural residents such as policy concern, policy perception, policy participation and policy expectation are deeple effected, but their behavior (or action) such as personal contact to the administrative agencies is not effected. This means that rural residents are deeple changed in their consciousness, but their behavior (or action) is not changed at the same degree as their consiousness because of their heritage, Confucianism.
