Eight cases of struma lymphomatosa confirmed by operation and microscopic study are reported because of the paucity of the reports on this condition occurring among Koreans and to emphasize the awareness of this disease among clinicians, especially surgeons for the proper management of the patients with goiters. These cases are found among 167 thyroid operations at the Severance Hospital, thus the incidence being 4.8%. All eight cases are found among female. The average age is 46 years, the youngest being 28 years and the oldest 59 years. The constant complaint is bilateral enlargement of the thyroid of firm and rubbery consistency. Dysphagia is predominent symptom and the others observed are tachycardia, palpitation and husky voice. The basal metabolic rates are within normal limit. In one case. in which carcinoma is suspected and subtotal thyroidectomy performed, the postoperative course is complicated with myxedema. The low incidence of r ostoperativemyxedema in this series is apparently due to inadequate follow-up. The pathologic features, grossly and microscopically are described._ Diminution of size of follicles, depletion of colloid in most follicles, oxyphilic change of thyroid epithelium, marked lymphocytic infiltration, lymphoid follicles with germinal center, mild to moderate fibrosis are observed microscopically in all cases.

The clinical data of one hundred and eight cases of carcinoma of the stomach, which had been diagnosed at the Department of Pathology, Yonsei University College of Medicine and- Severance Hospital during the last six years preceeding S-eptember 1960, and the pathological findings of 55 cases of them were studied. The average age of the patients was 48.6 years, the youngest being 26years and the oldest 70 years. It occured most frequently in the fourth and fifth decades and, 57.4 per cent of the total cases belonged to these age groups in contrast to the peak age incidence in the fifth or sixth decades among Caucasians. The male incidence was predominent over the female and the ratio was 3.5 to one. Some of the more frequent symptoms and their incidences were as follows; indigestion 70.3%, epigastric pain 69.4%, loss of weight 50.9%, tenderness 41.6%, palpable mass 40.7%, anorexia 37%, gastric discomfort 32.4%. The duration varied from 1(1)/(2) months 7 years to and was less than six months in 52.8 per cent of the total cases. The laboratory findings disclosed that 46,9 per cent of the cases were anemic, achlorhydria was found in 58.6%, hypochlorhydria in 21,8%, occult blood in the gastric juice in 80, and that in the stool in 60%. The radiological diagnosis was proved to be correct in 72,9 per cent of the cases. In the study of the causal factors, 10.9 per cent of the cases of carcinoma of the stomach were associated with chronic peptic ulcer and 12.7 per cent of the case of chronic peptic ulcereof the stomach were associated with carcinoma. One or more than one blood relatives of 5.6 per cent of the cases was found to havt carcinoma of the stomach one time or another. On the pathological examination, the classification based on the gross characteristics of growth and their incidences were as follows; carcinoma of no special type 47.2%, penetrating carcinoma 23.9%, fungating carcinoma 18.2%, linitis p1astica 7.3%, and superficial spreading carcinoma 3.7%. Eighty nine per cent of the cases were loca ted in the pylorus, 11% in the body, 38.4% along the lesser curvature, 11.5% along the greater curvature, 19.9% on the anterior wall, 27.2% on the posterior wall, and no cases were found in the cardia and along the greater curvature of the body. The most frequent single site was the lesser curvature of the pylorus, at which 32.8 per cent of the cases were situated. The size of the tumor varied from 0.6cm, in greatest diameter to 14cm, with the average being 6.3cm. The most frequent size was 5-10cm, and 45.2 per cent of the cases belonged to this category. In 42 per cent of the cases the tumors were less than 5cm, in greatest diameter and in 12.8 per cent they were greater than 10cm. On the histological classification, 67.3 per cent of the cases were adenocarcinoma, 10.9 per cent simple carcinoma, and 21.8 per cent mutinous carcinoma. At operation, 82 per cent of the cases disclosed metastasis to the regional lymph nodes.

본 연구에서는 균열 보수용 재료의 제품별 성능을 평가하기 위해 철도교량 보도부 균열 0.3mm이상의 균열 주입개소에 대해 현장 코어 샘플링 10개소를 시행하여 표면균열, 균열 깊이에 대한 에폭시 충진상태, 균열부의 부착력 등을 분석하는데 있다. 철도차량의 반복하중에 의한 진동 영향 및 계절적 특성을 고려하기 위해 균열보수 후 약 8개월이 경과한 다음 코어링을 실시하였으며 향후 철도교량의 균열 보수재료 선정 및 유지관리를 위한 기초자료로 활용하고자 한다. In this study, the surface cracks, epoxy filled state to the depth of cracks and the adhesion of cracks are analyzed in order to assess the performance of the materials for crack repair. For this, the 10 sites of field core sampling for cracking 0.3mm or more were conducted in the rail bridges crack injection sites. After eight months to repair cracks, the coring was performed to consider the impact of the vibration caused by cyclic loading of vehicle and also seasonality. The results can be used as the basic data for the selection of the crack repair materials and maintenance of the railway bridge in the future.
