PURPOSE: The purpose of this study was to identify the relationship of job stress, state of sleep, and depression and to identify factors influencing depression of emergency medical technicians. METHODS: The research was a cross-sectional, descriptive study. Data collection were done using self-report questionnaires with 162 emergency medical technicians working in hospitals who agreed to participate in the study. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients and multiple regression with the SPSS/WIN 18.0 Program. RESULTS: Depression had significant negative correlations with state of sleep, (r=-482, p<.001) and positive correlations with job stress (r=.196,p=.013). State of sleep had significant negative correlations with job stress (r=-.168, p=.033). The variance for life satisfaction was 23.7% (F=25.964, p<.001). Variable of state of sleep significantly predicted depression of emergency medical technicians. CONCLUSION: Considering these results, for emergency medical technicians' job stress, state of sleep, and depression, further studies are needed. Furthermore, there is a need to develop and implement new strategies to improve depression among emergency medical technicians.

174 patients who visited in the Department of Dentistry, College of Medicine, Yeungnam University from 1983. 7. 15 to 1986. 11. 30 were surveyed on the tendency of patient distribution and the state of Angle's classification. The results were as follows 1. There was increased visiting rate of patient per year. Female outnumbered male by a ratio of 1.3:1. 2. 8-15 age group was 74% in total visiting in the most frequency. The average visiting numbers of each month were higher among the vacation and was about 74% in that period. 3. As showed the living distribution, Nam Go and Su Sung Gu's patients were 53% of the total. 4. As the motive of visiting in Dental Department, patient of 30% in total patients visited for themself to receive orthodontic treatment and other was introduced patients. 5. By classification, Class I malocclusion was 63% in total visiting patient, Class II malocclusion 17%, Class III malocclusion 20%. Crowding among Class I malocclusion was 60%.

PURPOSE: The purpose of the study was to investigate factors that influence university women with eating problems. METHODS: Study participants were 307 women from two universities. Self-report questionnaires which included items on eating problems, satisfaction with body shape, self-esteem, body mass index, and weight control methods were used. Data were analyzed using independent t-tests, chi2 tests, and a multiple binary logistic regression. RESULTS: About 20% of the undergraduate women were experiencing eating problems. The problematic eating group showed more dissatisfaction with body shape than the normal eating group, and used more diets, fasting, diet-products, and uretics/laxatives to control body weight. Significant predictors for the problematic eating group were diets, diet-products, BMI, self-esteem and dissatisfaction with body shape. The strongest predictors were diets; risk for women university students who had been on a diet was 15 times higher than their counterparts. CONCLUSION: It is pertinent for health professionals to start intervention programs to educate university women with eating problems. The contents should include information on healthy weight control methods, improving satisfaction with body shape and self esteem, as well as creating social atmosphere about healthy body shape for women.

Emphysematous cystitis is a rare condition characterized by gas collection in the wall and lumen of the bladder. We experienced three cases of emphysematous cystiris. All patients were female; one was associated with a long term history of diabetes mellitus and another with urinary indwelling catheter. All of the cases were easily diagnosed on plain radiograph and CT scan, and were successfully treated with antibiotic therapy. In one of the cases, however, associated abscess due to perivesical extension of inflammation was treated by combined external drainage.

STATEMENT OF PROBLEM: Dental implant which has been developed gradually through many experiments and clinical applications is presently used to various dental prosthetic treatments. To conduct a successful function of implant prosthesis in oral cavity for a long time, it is important that not only structure materials must have the biocompatibility, but also the prosthesis must be designed for the stress, which is occurred in occlusion, to scatter adequately of load support. Therefore, it is essential to give the consideration about the stress analysis of supporting tissues for higher successful rates. PURPOSE: Recently, many implant manufacturing company produce various taper design of root form implant, the fixture is often selected. However, the stress analysis of taper form fixture still requires more studies. MATERIAL AND METHOD: This study we make the element models that five implant fixture; Branemark system(Nobel Biocare, Gothenberg, Sweden), Camlog system(Altatec, Germany), Astra system(Astra Tech, Sweden), 3i system(Implant Innovations Inc, USA), Avana system(Osstem, Korea)were placed in the area of mandibular first premolar and prosthesis fabricated, which we compared with stress distribution using the three-dimension finite element analysis under two loading condition. RESULTS: This study compares the aspect of stress distribution of each system with the standard of Von mises stress, among many resulted from finite element analysis so that this research gets the following results. 1. In all implant system, oblique loading of maximum Von mises stress of implant, alveolar bone and crown is higher than vertical loading of those. 2. Regardless of loading conditions and type of system, cortical bone which contacts with implant fixture top area has high stress, and cancellous bone has a little stress. under the vertical loading, maximum Von mises stress is more higher in order of Branemark, Camlog, Astra, 3i, Avana. under the horizontal loading, maximum Von mises is more higher in order of Camlog, Branemark, Astra, 3i, Avana.

PURPOSE:The prevalence of childhood obesity has been increased rapidly, associated with high morbidity of dyslipidemia, cardiovascular risk factors and insulin resistance/hyperinsulinemia. Hyperinsulinemia in obese children may depend on either increased insulin secretion or decreased insulin clearance. We investigate whether insulin secretion and clearance are different between obese and normal weight children. METHODS:The body mass index(BMI), fasting serum glucose, insulin and C-peptide levels were measured in 101 children(52 obese children and 49 non-obese controls) in Ansan area, from 6 to 14 years old. Fasting serum C-peptide/insulin ratio, insulin/glucose ratio, homeostasis model assessment(HOMA) were calculated and compared between obese and control group. RESULTS:The fasting serum insulin and C-peptide levels were significantly higher in obese group than in controls. The C-peptide/insulin ratio was significantly lower and insulin/glucose ratio was significantly higher in obese group than in controls. There were positive correlations between BMI and fasting serum insulin level, fasting insulin/glucose ratio and HOMA. The prevalence of hyperinsulinemia is higher in obese adolescents than in controls. CONCLUSION: Our findings suggest that increased insulin secretion and decreased insulin clearance may contribute to hyperinsulinemia in obese children.
