OBJECTIVES: Health care workers(HCWs) are more likely to become infected with tuberculosis from patients in the hospital. When HCWs have an active tuberculosis infection, it is possible that they also become a source of infections to other HCWs and patients. METHODS: Tuberculin tests were performed with mantoux method using 5 units of tuberculin by infection control practitioners on Feb. 21, and Mar. 7, 1997. A total of 138 newly employed HCWs including 44interns and 94 nurses were tested. Results of skin test were interpreted by themselves according to the instructions. RESULTS: Among 138 personels, skin tests were negative in 27 personels (19.6%); 4 interns (9.1%) and 23 nurses (24.5%). There were 3 persons (2.2%) who had a history of tuberculosis which had been treated. CONCLUSION: The study showed that approximately 20% of newly employed HCWs had negative tuberculin skin test. Given the possibility of being infected with tuberculosis in the hospital, regular follow up of tuberculin skin test is warranted to protect HCWs,

An experimental study on the effect of the induced dislocation of the femoral head on the femoral anteversion was made in the hips of 55 rabbits, three to four weeks old. The results were as follows; l. In 49 of the 55 operated rabbits, a relative increase of anteversion was observed on the dislocated side, as compared with the nonoperated femur, the differences ranging from 3 to 55 degrees with an average of 20.0 degrees. 2. The anteversion angle of dislocated hip showed steady and gradual increase with the increase of age. 3. The anteversion increase was detected very early after operation; 3 of the 4 rabbits, belonging 4 to 7 days group after operation showed the anteversion increase. 4. The collapse of proximal femoral epiphysis was observed in 42 of the total 55 hips. The incidence of the collapse was higher in postoperative 4 weeks and more groups. 5. The color change, pale discoloration, of the articular cartilage was observed in 32 of the total 55 hips. The icnidence of pale discoloration was higher in the groups within 8 weeks after operation.

OBJECTIVES: This study was performed to investigate the effectiveness of the questionnaire. METHODS: Workers'health examination records, work environment record, and questionnaires of selected industries as samples were analysed using logistic regression analysis and discrimination analysis Results'Cases of bearing impairment (Dl+C) as dependent variables, and age, work duration and level of environmental noise as independent variables were selected for multiple unconditional logistic regression analysis. Odds ratio was 4.04 in hearing difficulty, 2.78 in tlnnitus and 1.08 in age. In the second analysis Noise induced hearing loss is selected as dependent variable. The OR in hearing difficulty was 3.67(95 % C.1. : 1.61 8.61), and was 1.09(95 % C.1. : 1.05-1.14) in age. Conditionnal multlple logistic regression analysis was performed. In hearing impairment as dependent variable, the OR of age was 1.02(95 % C.1. : 1.00-1.04) and other variables were not significant. However, NIHL as dependent, the OR of hearing difficulty was 4.57(95 % C.1. : 1.43-14.67). According to multiple logistic regression adopting each items of questionnaire as dependent variable, the only item of hearing difficulty showed significant difference with hearing ability. The discrimination analysis was performed with the class variable of hearing impairment, and discrimination variables of age, work duration, and environment noise level. The sensitivity of 59 %, and specificity of 88 %, and average error count of 23 % were obtained. When the numbers of items answered in questionnaire were assumed as the parameter of judgement for noise induced hearing loss (NIHL), the highest sensitivity and specificity were 33.5% and 49.0% in cases of more than two items answered. CONCLUSIONS: The development of items that is simple and discriminative mainly consisted of chronic and specific diseases related items is needed. Computerization for newly developed items might be needed to establish effective surveillance system for NIHL in the future.
