We have attempted to define the acetabular remodelling after varus derotation osteotomy and limitations of pelvic osteotomy in the treatment of DDH. We studied the case of thirty eight patients (42 hips) who were divided into three groups according to age at operation and into two groups, subluxation with acetabular dyaplasia and complete dislocation. The cases were evaluated the influence of femoral remodeling, age, acetabular response and instability and requirement of other additional surgery. The length of follow up ranged from two to fourteen years. A return to a valgus femoral neck shaft angle by remodeling was observed in case without avascular necrosis of femoral head. Acetabular correction by remodeling occurred in case of well reduced the femoral head in the socket. Acetabular remodeling was observed even in age of 8. Twenty eight of 42 hips which were complete dislocation required no pelvic osteotomy. A varus derotation osteotomy is a necessary procedure for hip stability and open reduction in treatment of DDH. Good results should be anticipated in patient whose femoral head was well seated in the acetablum.

PURPOSE: To evaluate and compare the diagnostic findings and usefulness of MRI and MR arthrogram in recurrent anterior dislocation of the shoulder. MATERIALS AND METHODS: MRI and MR arthrogram of thirty-two cases of thirty patients with recurrent anterior dislocation of the shoulder were retrospectively analyzed to evaluate glenohumeral ligaments, pattern of labral injury, bony Bankart lesion, capsular stripping, Hill-Sachs lesion, and loose body. RESULTS: Labral abnormalities was detected on MRI in 23 cases(72%) and MR arthrogram in 22 cases(69%) as labral tear, detachment, and deficiency. All cases involved anteroinferior labrum. On MR arthrogram, labral abnormalities was confined to anteroinferior portion in 4 cases(18%), extended into midglenoid level in 13 cases(59%), and that into anterosuperior portion in 5 cases(23%). Capsular stripping was noted on MRI in 6 cases(19%) and MR arthrogram in 12 cases(38%). Loose body was detected only on MR arthrogram in 5 cases (16%). Bony Bankart lesion and Hill-Sachs lesion was detected equally on MRI and MR arthrogram in 2 cases (6%) and 21 cases(66%) respectively. We obtained identical findings on both MR arthrogram and operation field in 6 patients. CONCLUSION: MRI with its excellent soft tissue contrast resolution and multiplanar imaging capafility helps detection of labral injury in recurrent anterior dislocation of the shoulder. MR arthrogram is slightly invasive, but shows good artatomic details of labral-ligamentous-capsular relationship and thus provides accurate detec- tion of pattern of labral injury, capsular stripping, and loose body.

To evaluate the health risk of the workplace environment of a general hospital toward the hospital workers, a questionnaire survey on the perception of risk at the workplace environment and environmental measurements at 27 locations with 240 workers in the hospital were made from October 25th, 1993 to October 30th, 1994. The results were as follows; 1. By the environmental measurements, 86 workers(36%) were found to be exposed to poor or harmful degree of general illumination, 193 workers(80%) were exposed to poor or harmful local illumination, 34 workers(14%) were exposed to poor or harmful degree of thermal condition and l80 workers(75%) were exposed to poor or harmful noise level, but nobody was exposed to poor or harmful dust and toluene concentration. Also nobody was exposed to poor or harmful level of radiation or anticancer/antibiotic agents. 2. The subjective perceptions on the environmental conditions felt by the workers were different from the objective findings by the environmental measurements. The workers underscored the poor illumination state and overscored the dust concentrations. Also workers oversensitized about the thermal condition, the noise level, the radiation level, the toluene concentration and anticancer/antibiotic agents. 3. The sources of noise were the dialogue(179 workers) and the office instruments(131workers). The sources of dust came from the clothes(108 workers) and the building materials(79 workers). 4. The questionnaire survey showed that the 28 workers were exposed to poor or harmful level of the antibiotics, 10 workers to alkali or acid and 6 workers to drug dust in the pharmacy but the above findings could not be proved by the environmental measurements.

PURPOSE: The purpose of this study was to analyze and clarify the meaning of the concept, assertiveness. METHOD: This study used Walker and Avant's process of concept analysis. RESULTS: 1. Attributes of assertiveness were defined as 1) Self-esteem 2) Comprehension to others 3) Clarification of the subject 4) Verbal communication 5) Non-verbal communication 2. The antecedents of assertiveness consist of these facts 1) The occurrence of a conflict situation 2) The occurrence of will to stick to one's opinions 3. There are consequences occuring as a result of assertiveness 1) Positive self-confidence 2) Increased comprehension or consideration to others 3) Expand of mutual respect 4) Maintenance of continuously cooperative relationship with each other 5) Output of acceptable results to each other. CONCLUSION: Assertiveness is a core human behavior and is key to interpersonal relationships. Using the components of the concept of assertiveness, many conflicts in a nursing situation can be effectively prevented.

The study consists of an analysis of 39 cases of all kinds of granulomatous lesions in the colon observed at our X-ray department during 3year period between Jan. 1960. and the end of. 1962. Of these 39, 13 cases were Crohn's disease of the colon and 15 cases were tuberculous colitis. The remaining 11 cases were due to ulcerative colitis 3, amoebic colitis 4, and non-specific pericolitis 4. 17 males and 22 females were seen and, the peak incidence was from 40 to 49 years of age. The diagnosis of each granulomatous lesion was confirmed by tissue examination obtained by exploratory celiotomy or by biopsy. Crohn's disease and tuberculos colitis were more frequently encountered in the large bowel rather than in the ileo-cecal region. Granulomatous lesions in the colon must be differentiated from a number of causes of large bowel pathology e. g. carcinoma or lymphoma. The diseases with which it is more commonly confused are ulcerative colitis, tuberculous colitis, Crohn's disease and amoebic colitis. X-ray features of each of these granulomatous lesions are presented in detail and the points of differential diagnosis are discussed.

The effects of Clonorchis sinensis, Hymenolepis nana and Toxocara canis infection on fat absorption in the intestine were studied. For this purpose, I131-Triolein was given to the animals which were infected by those parasites, and amounts of the excretion in the feces were counted and following results were obtained. In the Clonorchis sinensis infected group, the excretion of Triolein was increased to 4. 10~4.49% compared with that of the control group. In the Hymenolepis nana infected group, the excretion of Triolein was increased to 4~5% compared with that of control group. In the Toxocara canis infected group, the excretion was about twice as much as that of the control group. It is concluded that parasite infection in digestive system diminishes fat absorption in gastrointestinal tract of the host.

To find the factors associated with the teaching evaluation by the students, data were collected through a questionnaire from 106 students in a premedical course at a medical college at November, 1994 after a series of lecture for a semester. The results are as follows : 1. Chronbach's alpha coefficients by part of evaluation were 0.8544 for teacher part, 0.7405 for the learner part and 0.7468 for the environment of the teaching. 2. Students gave low score of the evaluation for the items of questionnaire like contribution to creative thinking by lecture, good communication with the teacher, speed and amount of lecture, the appropriateness of textbook. Students gave high score of evaluation for the items of questionnaire like the scrutiny of the lecture hours, the appropriateness of test and homework assignments, composition and progress of the teaching schedule and preference and expression of the lecture. 3. The evaluation scores were significantly high among the student who were satisfied with the lecture, expected high score for the test, low number of absence, the high perception of the necessity about the subject to medical students. The sex of students, the difficulty of the subjects and the burden of learning were not associated with the point of evaluation. 4. Among the learner's attitude, positive and sincere learning attitude, scrutiny of pressure to the lecture, diligent homework assignment, and good preparation for the lecture were associated significantly with the point of evaluation. 5. The correlation coefficients between evaluation result and associated factors were 0.476 for the learner's attitude, 0.312 for the environmental factor of lecture, 0.296 for the expected score and 0.628 for the degree of satisfaction. Negative correlation were shown between the evaluation point and the number of absence(r=-0.248) and the backside preferred seat at lecture room(r=-0.274). In conclusion teaching evaluation by the students kept relatively high reliability in measurements and the evaluation results were associated with the several factors, so for the effective methods of implementation of teaching evaluation and utilization of the results, systematic of the results, systematic and deeper study must be made.
