The purpose of this study is to investigate the effect of job stress and social support on the organizational effectiveness of hospital employees and to examine the role of social support in the experience of job stress among the employees. Previous studies have yielded mixed results regarding the role of social support. Some studies provide supporting evidence for the buffering effect of social support, while others do not. Still others report findings about reverse buffering effects. These inconsistent findings are, in part, accounted for by methodological problems such as poor measurement, small sample size, and the existence of high multicollinearity. To examine more rigorously the role of social support in relation to the negative effects of job stress, this study was carefully designed to overcome methodolgical shortcomings found in the past research. In addition, unlike the previous studies, which were concerned mostly with health-related variables as consequences of job stress, in this study, three work-related variables (job satisfaction, organizational commitment, and intent to stay) which had close relationships with organizational effectiveness were examined as output variables. The sample used in this study consisted of 353 employees from a university hospital in the suburbs of seoul. Data were collected with self-administered questionnaires and analyzed using canonical analysis and hierarchical regression analysis. The results of this study indicate that; (l) job stress has negative main effects on job satisfaction, organizational commitment, and intent to stay; (2) social support has positive main effects on the same three output variables, (3) social support does not moderate the harmful effects of job stress on the three outcome variables, and (4) the three-way interaction effects of (social support * job stress * gender) and of (social support * job stress * education) are not supported The implications of these findings for the management of human resources are discussed.

PURPOSE: To evaluate the treatment results of geriatric intertrochanteric fractures by using Asian-Pacific Gamma nails. MATERIALS AND METHODS: From June 1994 to June 1997, 58 cases of the intertrochanteric fractures were treated with Asian-Pacific Gamma nail, particularly compression hip screw fixation complications such as communited fracture involving lesser trochanter, transverse or reverse oblique intertrochanteric fracture. We evaluated the bone union time, neck-shaft angle, lag screw sliding by follow up radiographs, and studied complications and intraoperative cautions. RESULTS: The average age was 74.4 years old, the mean duration of follow-up was 17 months, the mean duration of bone union was 14.2 weeks, the average neck-shaft angle was postop. 133+/-2.78 degree and last follow-up was 129.5+/-3.37 degree, and the average lag screw sliding was 4.7+/-3.16 mm. Intraoperative complications were difficulty in distal drilling (posterior drilling) in 4 cases, fracture displacement by nail insertion in 3 cases, and postoperative complications were coxa vara in 13 cases, superior cutting out of lag screw with nonunion in 1 case and superficial infection in 1 case. The entry portal must be formed by awling. The fracture displacement when inserting nail could be prevented by proper reaming after inserting the C-shaped guide pin, and posterior drilling could be avoided by confirming the locking between target device and nail. CONCLUSIONS: We conclude that the Asian-Pacific Gamma nail could appropriately treat the osteoporotic, communited intertrochanteric fracture in elderly patients and we obtained satisfactory results.

Clinical observation was performed on 23 children with Guillain-Barre syndrome which were hospitalized at the Pediatric ward of Han Yang University Hospital, from July 1975 through May 1991.@ES The results were as follows: 1) The ratio of male patient to female was 2.8:1 and 47.8% of total GBS patients were between the ages 1 to 5 years. 2) The highest seasonal incidence of GBS was seen in summer and there was no significant variation of GBS annually.3) Preceding illness of GBS was found in 60% of the total patients, and upper respiratory infection was the most common (65%). 4) Muscular paralysis or weakness in extremities was the most common chief complaints on admission, and repiratory difficulty, vomiting, diarrhea, swallowing difficulty and myalgia were followed. 5) The sites of paralysis on admission were upper and lower extremities in 14 GBS patients (60.8%), lower extremities in 7 GBS patints (34.8%) and respiratory muscle in 4 GBS patints (17.3%), respectively. 6) The protein content of cerebrospinal fluid was elevated in 18 GBS patients of total (78.3%) on admission and remnant 5 GBS patients showed increased protein later. 7) There was a tendency that recovery time in 5 GBS patients with muscular fibrillation on E.M.G. was longer than in 4 GBS patients without muscular fibrillation. We thought further studies on critical evaluation and better treatment for GBS were needed.

Purpose:
We report a lenticular cyst in an 8-year-old boy.Case summary: An 8-year-old boy visited our clinic with reduced visual acuity. On slit lamp examination, an immobile lenticular cyst was evident on the posterior lens capsule of the left eye. There was no other abnormality. He had no history of ocular trauma or surgery. His Snellen best-corrected visual acuities (BCVAs) were 1.0 (-0.50 Dsph 0.50 Dcyl ×180°) in the right eye and 0.3 (+3.25 Dsph 1.00 Dcyl ×180°) in the left. After diagnosis of a primary lenticular cyst and anisometropic amblyopia, the child was prescribed glasses and occlusion therapy (8 hours daily). After 3 months, the BCVA improved to 0.9 in the left eye and was maintained. No change in lenticular cyst size was observed during 8 months of follow-up.
Conclusions
Primary lenticular cysts are very rare in children. When the cyst is too small to occlude the visual axis, amblyopia treatment (glasses and occlusion therapy) is preferable to surgery, being both non-invasive and effective.

An analytic study on 431 cases of cardiac conduction disturbance has been made by review of the clinical records and electrocardiograms taken from the adult patients registered at Kyung Hee University Hospital for 3 years from May, 1973 to April, 1976. 1. The total incidence of conduction disturbance was 6.50%, the atrioventricular block 3.14% and the intraventricular block was 3.36% of total 6,616 cases of E.C.G. reviewed. Among of these, the first degree atrioventricular block was 3.02% which was the most common occurred one, the incomplete right bundle branch block was 2.25% and the complete right bundle branch block was 0.57%. 2. The ratio of male to female was 1.6:1 for the first degree atrioventricular block, and 1.6:1 for the incomplete right bundle branch block, 2.5:1 for the complete atrioventricular block, 2:1 for the left bundle branch block, and 1.7:1 for the complete right bundle branch block. The first degree atrioventricular block was seen most frequently in the fifth and sixth decade of age group, and the third degree block was over 40 years. The incomplete right bundle branch block in order was forth decade, third decade and fifth decade. The complete right bundle branch block and left posterior hemiblock were common in the sixth decade. The left bundle block and the posterior hemiblock were common in fifty years of age group. 3. The cardinal underlying diseases of the first degree atrioventricular block among cardiac diseases group in order of frequency were: hypertensive heart disease (25.0%) arteriosclerotic heart disease (8.0%) and rheumatic valvular heart disease (5.0%). The most common etiology of those non-cardiac disease group was neuropsychiatry disorder (11.5%) and the next was infection (11.0%). 4. All of the complete atrioventricular block were associated with the cardiac disease, that is, 57.0% with arteriosclerotic heart disease, 28.5% with pericarditis and 14.3% with hypertensive heart disease, respectively. 5. The cardinal underlying disease of the incomplete right bundle branch block in order of frequency were: hypertensive heart disease (10.7%), arteriosclerotic heart disease (8.1%) among the cardiac disease group, and infections (15.4%) among the non-cardiac disease group. The incidence of healthy persons was 14.1%. 6. Those of complete right bundle branch block in order of frequency were: arteriosclerotic heart disease (13.2%), and hypertensive heart disease (10.1%) among the cardiac disease group, and infection(13.2%) and neurosis (10.1%), respectively among the non-cardiac disease group. 7. The major etiologies of the left bundle branch block was hypertensive heart disease and arteriosclerotic heart disease (33.3% each), and that of left posterior hemiblock was showed arteriosolerotic heart disease and cor-pulmonale. The most common etiological disease of the left anterior hemiblock was hypertensive heart disease in cardiac disease group, and infection and gatrointestinal disease in non-cariac disease group. 8. The abnormal electrocardiographic findings with the first degree atrioventricular block were left ventricular hypertrophy (24.8%), sinus tachycardia (11.0) and sinus bradycardia (5.8%). Those with the complete atrioventricular block were right ventricular hypertrophy (15.8%) and left bundle branch block (15.8%). In complete right bundle branch block, the majority (52.5%) showed single sign without other abnormality on E.C.G. In the left bundle branch block, there were 18.9% of left ventricular hypertrophy and 15.7% of first degree atrioventricular block. In the left anterior hemiblock, there were 28.5% of right bundle branch block, and 19.0% of right ventricular hypertrophy. In the left posterior hemiblock, there were 40.0% of atrial fibrillation and 20.0% of left atrial hypertrophy.
