This investigation evaluated patients who received Steri-Oss implants from the Dental Hospital of Chosun University during the period from March 1989 to August 1997. 346 fixtures of 127 patients were included in this study . The results were as follows ; 1.The follow-up period was defined as the period between the surgical placement of the implants and the last follow-up examination. The mean follow-up period was 2.17+/-1.21 years. 2.The period between fixture installation and second surgery was 0.71+/-0.44 years in the maxilla and 0.46+/-0.21 years in the mandible. 3.The number of fixtures which were installed in the upper jaw(112) was less than that in the lower jaw(234) and in the posterior region(260) was more than in the anterior region(86). 4.The length of fixture which was most frequently used was 12 mm and least was 8mm. Screw implants were installed more than cylindrical implants. 3.8mm implant was the most common implans, followed by 4.5mm and 3.25mm. 5.The number of augmentation cases was more than that of non-augmentation cases and the rate of augmentation cases in the maxilla was more than that in the mandible. 6.Implant restorations for partial edentulos patients(94cases) were more than single-tooth implant restorations(33cases) or implant restorations for complete edentulos patients(10cases). 7.Free-standing prostheses for partially edentulous patients were more commom than any other type of connection between implants and natural teeth. 8.Plaque Index(0.95+/-0.74) and Gingival Index(0.31+/-0.52) were very similar around the natural teeth and reflected an acceptable level of plaque and gingivitis control. Mean value for keratinized mucosa index(1.93+/-1.20) remained fairly constant around level 2(1-2 mm keratinized epithelium). 9.Patients were generally satisfied with implant in terms of comfort, function, speech and esthetics. 10.There was not a statistically significant differences in overall survial rate between implants placed in the maxilla (91.5%) and those placed in the mandible (93.8%). Fourteen implants lost before the prosthetic rehabilitation and eleven implants lost following variable periods in function after the prosthetic phase of the treatment. 11.Cause of implant failures was exfoliation or removal of fixture due to non-osseointegration before the prosthetic rehabilitation or due to fracture of fixture, masticatory pain after the prosthetic rehabilitation. 12.The survival rate of Steri-Oss implants using the Kaplan-Meier statistical analysis was 93.8% at 2 year and 86.6% at 5 year. In all cases, implant losses occured predominantly in the healing period. There was a steep decline in the rate of implant loss after the first year. 13.The survival rate of Steri-Oss implants in the anterior region was 94.8% at 2 year and 94.8% at 5 year and that in the posterior region was 92.8% at 2 year and 75.9% at 5 year. In conclusion, this study revealed a number of parameters and guidelines for achieving an optimal success rate in osseointegration.

BACKGROUND: Social support is defined as interpersonal transaction ; the giving of symbolic or material aid to another. It has been shown to have both buffering effects and direct beneficial effects on diverse health related outcomes. But there has been the dearth of well-validated measurement instruments. This article describes the development of Korean version of the Duke-UNC functional social support questionnaire(DUFSS), focusing on the aspect of social support. METHODS: The 13-item, self-administered questionnaire was translated to Korean language. It was evaluated on 177 patients attending the family medicine clinic of Seoul National University Hospital during one month(November, 1996.) Comparisons to the family APGAR, COOP/ WONCA functional status chart are made to assess validity. Factor analyses are performed. Correlation of the questionnire score with the sum of family APGAR and each items of COOP/ WONCA functional chart are measured Internal consistency are evaluated. RESULTS: The questionnaire score are correlated with significantly correlated with social activity item. The total Cronbachs alpha is calculated as 0.89. The four content areas developed by factor analyses are donfidant support(items 8, 9, 10), af fective support(items 4, 5, 6, 7), instrumental support(items 3, 12) and quantity of support(item 1). These shows similarity to American study results. CONCLUSIONS: The Korean version of the Duke-UNC functional social support questionnaire has been documented as having high reliability and moderate validity. It covers two dimensions well(confidant support, affective support) with a small enough number of questions. Instrumental support may need further study.

This study was conducted to evaluate the relationship between change in obesity indices and change in serum lipids in adult male workers. Two-hundred-eight adult male workers of an industry in Taegu city were followed-up from 1991 to 1995. Height, weight, circumferences of hip and waist, blood pressure were measured and serum lipids were analysed. Data on life style were obtained using self-administered questionnaires. Mean differences of anthropometric measurements between 1991 and 1995 were as follows; 1.63kg in weight, 3.61cm in waist circumferences, 4.23cm in hip circumferences, 0.52kg/m2 in BMI and -0.021 in WHR. Those of lipids were as follows; 15.09mg/dl in total cholesterol, 20.43mg/dl in triglyceride, 9.40mg/dl in HDL-cholesterol, 2.87 in MI-index(p<0.01) and 350mg/dl in LDL-cholesterol. The changed value of BMI and Katsura index were strongly correlated with that of total cholesterol(r=0.174, p<0.05), the changed value of BMI correlated with that of triglyceride(r=0.374, p<0.01) and the changed value of weight correlated with that of MI index(r=-0.173, p<0.05). The changed value of WHR was significantly correlated with that of total cholesterol(r=0.162, p<0.05), however, was not significantly correlated with HDL-cholesterol, LDL-cholesterol, triglyceride and MI index. The changed value of weight, BMI and Katsura index were correlated with that of triglyceride(r=0.262, p<0.01; r=0.267, p<0.01; r=0.258, p<0.01) and the changed value of MI index(r=-0.143, p<0.05; r=-0.158; r=-0.144, p<0.01), adjusting the pattern of change in life style. The changed values of HDL-cholesterol and MI index between 1991 and 1995 in low WHR group were significantly higher than those in high WHR group(p<0.05, p<0.01), adjusting the baseline value of them. Similar pattern was observed when considering Katsura index. When stratifying by BMI value of 1991, in low BMI group, the changed value of HDL-cholesterol and MI index showed the same pattern as above, however the of triglyceride was statistically higher in obese group than in non obese group(p<0.05). In conclusion BMI might be a better indicator to predict serum lipids change than other obesity indices.

Lipoma arborescens is a rare intra-articular lesion consisting of a villous lipomatous proliferation of the synovial lining. We experienced one case of lipoma arborescens of knee which was associated with avascular necrosis of femoral head. This case report draws the attention to history, physical findings, MR images, pathologic findings and arthroscopic appearance of this rare lesion. Arthro;copically, the lesion appears as a synovial lesion with numerous fatty-appearing globules and villous projections. Although the etiology is unknown, lipoma arborescens has been described in association with osteoarthritis, rheumatoid arthritis and diabetes mellitus. MR imaging is diagnostic choice to differentiate the lesion from rheumatoid arthritis, pigmented villonodular synovitis and synovial chondromatosis in those patients who present with chronic, swollen and painfui joint. Arthroscopic removal was effective in this case and we think that treatment choice of this lesion is arthroscopic removal.

As a new concept of resistive exercise, isokinetic exercise was developed during the early 1950's. In isokinetic exercise, the subject works at a fixed speed against variable and totally accommodating resistance. The isokinetic equipment has been used widely as a therapeutic modality in clinical setting, as a training and testing device for sports practicians, and as a method for scientific examination of postoperative status of muscles and joint function for orthopedists. In order to acquire the isokinetic normative data of the knee for clinical use, we examined the flexor and extensor muscle force of the knee joint in 160 subjects with Cybex II. The results were as follows; 1. Mean values of extensor strength were 76.04 ft.-1bs in right knee 75.45 ft.-lbs in left knee, 78.42 ft.-1bs in dominent hand side leg 73.84 ft.-1bs in non-dominent hand side leg, and 82.52 ft.-1bs in dominent leg 71.93 ft.-lbs in non-dominent leg. 2. Sex difference of extensor strength were 95.13 ft.-lbs in male 55.98 ft.-1bs in female, and that of flexor strength were 54.90 ft.-1bs in male 33.68 ft.-1bs in female. 3. Mean of position angle of maximal torque were between 58° and 65° for extensors, 35° and 45° for flexors. 4. Mean of total range of motion at working isokinetically with 60°/sec speed was 99°. 5. Mean values of extensor power were 54.43 ft.-1bs in male 30.63 ft.-lbs in female, and that of flexor power were 35.99 ft.-1bs in male 22.42 ft.-1bs in female. 6. Strength and power decreased as ages getting old, and there was significant diminish between 4th decade and 5th decade. 7. Power endurance had more difference when it was compared with occupation. Mean value of power endurance was between 12 times and 18 times.

Coronary artery fistula is an unusual anomaly in elderly patients that consists of a communication bet- ween one of the coronary arteries and other cardiac chambers or veins. It causes many cardiac compli- cations due to hemodynamic changes, and thus has recognized its clinical significance. It occurs usually in congenital origin, but also occurs secondarily in traumatic or neoplastic or artherosclerotic coronary diseases. Congenital coronary artery fistula is a very rare congenital anomaly that results in multiple hemodynamic complications. It has reported rarely in elderly patients, that induces myocardial ischemia due to coronary steal syndrome and heart failure that caused by diastolic volume overload via a left to left shunt. We observed a 68-year-old male patient with exertional chest pain and dyspnea, in whom selective coronary angiography revealed abnormal reticular communication between left anterior descending artery and left circumflex artery and drained to left ventricle through multiple microfistulous channels. We report this patient case who complicated by myocardial ischemia and left ventricular failure those caused by hemodynamic complication due to multiple coronary artery-left ventricular fistulae.

PURPOSE: The purpose of this study was to identify the relationship between self-esteem and sexual attitude in healthcare college students, and also to provide a basis for sexual health education programs to help establish healthy sexual attitudes. METHODS: A survey was conducted with 218 unmarried students attending the healthcare colleges in B and U cities. Data were collected from October 15 to November 10, 2015 and analyzed using Stepwise multiple regression with SPSS PASW 18.0. RESULTS: Mean score for self-esteem was 3.23±0.46 out of 5 and sexual attitude 2.64±0.54 out of 5. Self-esteem and sexual attitude had a negative correlation (r=-.169, p=.012). Among sub-variables of sexual attitude, negative correlations were found between self-esteem and premarital chastity (r=-.207, p=.002), and between self-esteem and homosexual attitudes (r=-.167, p=.013). There were statistically significant differences in sexual attitude according to perceived intimacy with mother (β=-.228, p<.001), year in college (β=.135, p=.047), major (β=.148, p=.023), religion (β=-2.429, p=.016), and homosexual tendencies (β=.139, p=.037). These factors explained 14.6% of the variance in sexual attitude. CONCLUSION: Findings demonstrate the importance of self-esteem for sexual attitudes. This finding should be used in the development of healthcare college students, promotion programs to enhance healthy sexual attitudes.

Acute focal bacterial nephritis (AFBN), synonymous with acute lobar nephronia (ALN) or focal pyelonephritis, is an inflammatory mass without liquefaction caused by severe acute bacterial infection of kidney. Unless treated effectively, progression to a renal abscees may ensue. Clinically, AFBN presents as acute pyelonephritis, and radiologically, as focal swelling or mass. The distinction between AFBN and renal abceess or even tumor may be confusing and difficult. Ultrasonography and computerized tomography(CT) aid in establishing the correct diagnosis. However, the appearance of AFBN on sonography and CT is by no means pathognomonic. Benign or malignant renal tumors may have a similar appearance. With the clinical history, a high index of suspicion, and follow-up studies after institution of medical treatment may further aid in the differentiation. Herein we report 2 cases of AFBN, which were presented as renal masses.
