This study was conducted to evaluate the association of job characteristics and stress indicators, from May 1st to 10th, 1996. The study population was 210 workers (clerical workers, 67; engineers, 82; assembly line workers, 61) engaged in a television manufacturing company. A questionnaire method was used to collect the data regarding to job demand, job control, behavioral type, life style and psychiatric symptoms. Clinical examination was conducted to measure blood pressure, serum cholesterol, fasting blood sugar and HbA1c. Percentage of high subjective job strain group was significantly higher in clerical workers(9.0 %) than in engineers(4.9 %) and in assembly line workers(3.3 %) (p < 0.01). Mean values of fasting blood sugar and HbA1c were significantly different between types of occupation and were the highest in clerical workers (p < 0.05). Significant association was found between perceived job characteristics and psychiatric symptom score (p < 0.01). The more job demand and the less job control was, the higher psychiatric symptom score was reported. Diastolic blood pressure was significantly related to job control (p < 0.05). The more job control was, the higher blood pressure was reported. In multiple regression analysis, job demand, job control and age were significant variables explaining the psychiatric symptoms and R2 was 0.23. Perceived job characteristics and type of occupation were not significant in explaining diastolic blood pressure and cholesterol. Type of occupation, job demand, age and BMI were significant variables explaining lasting blood sugar and R2 was 0.25. Type of occupation was the only significant variable explaining HbA1c and R2 was 0.07. According to this result, occupational type and subjective job characteristics must be considered in study of job stress. As a result of multiple analysis, subjective job characterics are significantly related to psychiatric symptoms and type of occupation is significantly related to fasting blood sugar and HbA1c.

Adenosis tumor is a ra re tumor of the breast and primarily consists of adenosis. Authors report a case of surgically proved adenosis tumor in a 31-year-old woman. Mammogram showed a Iobulated, well-circumscribed mass with several surrounding radiolucent halos. In the center of the mass several linear radiolucent densities were seen with the appearance of a conglomerated well-circumscribed mass such as fibroadenoma. These linear radiolucent densities were consistent with the fat between the fibrous sclerosis in pathologic specimen. Ultrasonogram showed a well-circumscribed mass with homogeneous low echogenicity, partial posterior enhancement, and bilateral acoustic shadowings.

By means of hospital-based data over 8 years we sought to evaluate the clinical indications and incidence of emergency peripartum hysterectomy by demographic characteristic and reproduction history. From the obstetric record of all deliveries at Chung Goo Hospital between Jan. 1, 1990, and Nov. 31, 1997, we identified all women undergoing emergency cesarean hysterectomy, calculated incidence rates, conducted statistical tests of linear trends and heterogenety, and observed the clinical indicatons preceding the onset of this procedure. There were 16731 deliveries during this period, Cesarean hysterectomy was performed in 24 of 5993 cesarean sections(0.40%) and in 10 of 10738 vaginal deleveries(0.09%), so more frequently after cesarean section than vaginal delivery. The age of patients varied from 22 to 40 years old. The higher the age and the parity of patients, the higher incidence of cesarean hysterectomy was noted. The most common indication of cesarean hysterectomy was uterine atony(52.94%) followed by placental disorders(41.18%), uterine myoma with pregnancy(2.9%) and uterine rupture (2.9%). All patients who had hysterectomy received transfusion from 1 pint to 57 pints. The postoperative complications were bladder injury, febrile morbidity, disseminated intravascular coaguolopathy and wound disruption. There were three maternal deaths, the cause was disseminated intravascular coaguolopathy and amniotic embolism. The data identifiy uterine atony as the primary cause for gravid hysterctomy. The data also illustrated how the incidence of emergency peripartum hysterectomy increases significantly with increasing parity, especially when influenced by a current placenta previa or a prior cesarean section. Maternal morbidity remained high.

MR imaging of the brain in 34 patients were reviewed to characterize the MR findings of brain damage due to perinatal hypoxic insult All the patients had a history of perinatal hypoxia and showed abnormal brain MR findings. Out of 34, eight infants were born premature and twenty-six were born at term or post-term. MR findings were analysed for the extent and location of abnormalities of the white matter, cortical abnormality. Corpus callosum atrophy, and abnormal progression of myelination. The major abnormalities were abnormal signal lesions or atrophy of the cerebral white matter and gyral atrophy of the cerebral cortex. The distribution of white matter lesions well correlated with maturity of the brain at the time of hypoxic insult. Periventricular and deep white matter lesions predominated in the premature-born patients. Corpus callosum atrophy was frequently seen. Reflecting the location of white matter injury. Delay in myelination was present in 55%. MR is a very useful diagnostic imaging modality and guide for the prediction of prognosis by accurate depiction of the location and extent of brain damage due to perinatal hypoxic insult.

Clear cell sarcoma is a rare malignant rumor of the kidney which occurs in children and is differentiated from Wilms' tumor by its different clinicopathologic features and natural history. Previous studies indicate that this tumor may be of mesenchymal cell origin; however, this has not been proven conclusively. Further accumulation and study need to be conducted in order to clarify the histogenesis of this tumor. We report two cases of clear cell sarcoma of the kidney which occurred in a 2 and a half-year old and a 2-year old boy. This report places special emphasis on the clinicopathologic characteristics of these two cases including electron microscopic and immunohistochemical findings. Attempts were also made to differentiate the clinicopathologic aspects of clear cell sarcoma from Wilms' tumor and speculate on the histogenesis of this rumor.

OBJECTIVES : The primary purpose of this study was to investigate the effects of computerized cognitive rehabilitation training on inpatients with schizophrenia in the rehabilitation unit. METHODS : Thirty-eight patients with schizophrenia from the Yongin Mental Hospital Rehabilitation Ward were randomly assigned either to a computerized cognitive rehabilitation group or to a control group. The rehabilitation group received 12 sessions of computerized cognitive rehabilitation training (Cog-Trainer) over 3 months. This training program consisted of ten units, each of which consisted of 3 levels, practice, application, and advanced. Neurocognitive functions were assessed at the beginning and end of the training period. Cognitive measures included Span of Apprehension (SPAN), Continuous Performance Test (CPT), Digit Span, Trail Making Test, and the Stroop Test. RESULTS : Compared to controls, subjects receiving computerized cognitive rehabilitation training experienced a significant improvement in attention, concentration, and working memory. CONCLUSION : These results indicate that computerized cognitive rehabilitation training can contribute to improvement in cognitive function of patients with schizophrenia. Further study to generalize these results is required.

The authors reviewed the charts of 128 patients(160 eyes) who underwent vitrectomy for the proliferative diabetic retinopathy from January 1993 to December 1995 and the results were analyzed in terms of visual efficiency. At the conclusion of the study, visual acuity improved in 96 eyes(60%), unchanged in 33 eyes(21%) and in 31 eyes(19%) became worse. Visual efficiency was increased from 11.9% preoperatively to 37.2% postoperatively in all patients. Patients under the age of 40 showed better results than the patients above the age of 40. The factors which affected the change in visual efficiency were age and preoperative intraocular conditions. The patients who had non-clearing vitreous hemorrhage without proliferative membrane revealed better prognostic results than the other patients. In 50 eyes (31.3%) of cases, maximal postoperative visual acuity was achieved in 4 weeks to 3 months after operation.
