We retrospectively evaluated the nature, distribution, and pattern of the traffic accidents in 1046 cases of traffic accidents transported to chungnam National University Hospital from Jan. 1987 Dec. 1988. We also evaluated the ability of the CRAMS Scale to predict injury severity and mortality, and the results were as follows: 1. The age distribution was most prevalent between 25-44 years(44.6%), the ratio of male to female was 2.9:1, and the ratio of male of female of the children and old age group was 1.6:1. 2. There was no significant difference in seasonal distribution. 3. Of 1046 cases, 39.8% was associated with Orthopedic Surgery, Neurosurgery, Plastic Surgery, and Genera Surgery were 38.8%, 20.3%, and 10.0% respectively. 4. In injury mechanism, motor vehicle accident was highest in incidence(50.7%), pedestrian accident, motorcycle accident, and bicycle accident were 23.4%, 18.6%, and 7.3% respectively. 5. The most frequently injured body region was head and neck(65.6%), and then extremity and pelvis was 37.3%, and abdomen was 10.9%. 6. Traffic accident developed in urban area was 1.4 times more frequent than rural area. 7. In elapsed time from arrival to death, 77.6% was died within first 24 hours and 33.6% was died at scene or less than 1 hour. 8. The overall mortality rate was 11.9% and in mortality rate according to department, Neurosurgery was 52.8%, Chest Surgery was 20.8%, and General Surgery was 13.6%. 9.

장일성,김지연,이희만 충남대학교 의과대학 지역사회의학연구소 1993 충남의대잡지 Vol.20 No.2

Fibroadenoma is the most common benign tumor of breast in human female between the age of 20 and 35 years. The great majority of patients should be treated by excisional biopsy to remove the tumor and establish the diagnosis. Authors have reviewed 110 case of fibroadenoma who underwent surgical operation during the period from Jaunary 1990 to Jaunary 1993 at the department of General Surgery in Chungnam National University Hospital. The circumareolar skin incision was selected if the tumor was compatible with benign fibroadenoma on the finding of preoperative mammogram and sonogram. But, the diagnosis was uncertain and the distance from the mass to nipple was over 3 cm, the skin incision was made on the just above the palpable mass. In order to minimize the seroma, hemostasis was taken completely, the use of electrocautery was restricted as possible, a close suction drain was kept to surgical dead space via the main wound by vaccum tube in case of leaving large dead space, and compressive dressing was applied on the defected wound site after the operation. The major complication after the excision of suspicious fibroadenoma was seroma, and its complication rate was about 8% (9/110 cases). But, another complication was not found. The rate of discharge at the first postoperative day was calculated to 73.2 % among the total patients and the remaining of all patients could be discharged at the second postoperative day. In conclusion, the young female who was under suspicion of fibroadenoma must be treated with excision and the excised specimen should undergo histologic examination to rule out carcinoma or to confirm the diagnosis. The associated major complications were revealed to minimal.

Ranitidine HC1(U-rantac^ⓡ) is a highly effective, rapidly acting histamine H2-receptor antagonist. It inhibit basal and stimulated secretion of gastric acid, reducing both the volume, and the acid pepsin content of the secretion. Now, It has been widely used for treatment of the peptic ulcer. We has investigated the effect of Ranitidine HC1 in the peptic ulcer and stomach cancer in 62 patients who had been admitted to the Department of General Surgery, Chungnam National Universtity Hospital from Jan. 1987 to Apr. 1987. The following results were obtained: 1. The prevalent age in duodenal ulcer was fourth decade, gastric ulcer, fifth decade, and stomach cancer, sixth decade, respectively. 2. The male to female ratio in duodenal ulcer was 2. 8 : 1, gastric ulcer, 2 : 1, and stomach cancer, 1:1. 3. After intramuscular injection of Ranitidine HCl in duodenal ulcer, volume of gastric secretion was decreased in 31ml/hr (36%) in male and 20m1/hr (33%) in female, and gastric acidity was decreased in 3. 5mEq/hr (54. 4%) and 2. OmEq/hr (48.8%), respectively. In gastric ulcer, the volume of gastric secretion was decreased in 14ml/hr (21. 9%) in male and 4m1/hr (7. 7%) in female, and the gastric acidity was decreased in 0. 9mEq/hr (39.0%) and 0. 6mq/hr(23. 1%), respectivly. In stomach cancer, the volume of the gastric secretion was decreased in 17ml/hr (28. 8%) in male and 15ml/hr (25.9%) in female, and the gastric acidity was decreased in 0.5mEq/hr (15.6%) and 0.6mEq,/hr (19.4%), respectively.

본 논문에서는 고준위 폐액 중의 장수명 핵종을 분리하기 위한 군분리 공정에서 추출 공정의 산도조절 목적으로 사용되는 기존의 회분식 개미산 탈질 고정 개선이 시도되었다. 연속식 개미산 탈질과 잔여 산의 전해 분해 공정 조합 시의 질산 및 개미산의 분해 특성과 그때 분해 생성물의 변화 특성에 대한 연구가 수행되었다. 연속식 개미산 탈질에서는 약 30분 내에 정상상태에 도달하며 용액의 탈질 반응기 내의 체류시간은 최종 산도에 영향을 주고, 회분식처럼 개미산/질산의 몰 비가 1.5일 때 탈질에 의한 최저산도 값을 보여주었다. Ti-IrO_(2) 전해 반응기를 사용시 전류밀도에 따른 질산과 개미산의 분해 속도는 각각 9.33×10^(-3), 1.37×10^(-2)M(hrㆍ㎃/㎠)이었다. 질산은 Ti 음극의 환원에 의한 개미산은 IrO_(2) 양극의 산화에 의해서만 분해되었다. 본 연구에서 새롭게 제시된 연속식 개미산 탈질-잔여 산 전해 분해 공정의 조합은 2.0M 질산 용액을 최종적으로 약 0.1M 이하까지 연속 처리할 수 있었다. This work has improved the conventional batch denitration by formic acid which has been used for controlling the acidity of solution for the solvent extractions to partition the long lived-radionuclides from the high level radioactive liquid waste. The characteristics of destructions of nitric acid and formic acid and their destructive products in a continuous denitration process combining a continuous denitration system by formic acid and an electrolytic residual acid-trimming system suggested in this work was evaluated. The continuous denitration by formic acid reached a steady state in 30 minutes and showed the dependence of the final acidity on the residence time of feeding solution into the reactor. Also the system had the lowest final acidity at a mole ratio of formic acid and nitric acid of 1.5 like the batch denitration. In a Ti-IrO₂ electrolytic cell, the destructive rates of formic acid and nitric acid were 9.33×10^(-3) and 10^(-2)/M(hr·mA/㎠), respectively. The nitric acid and the formic acid were destructed through the reduction at the T₁ cathode and the oxidation at the IrO₂ anode, respectively. The newly suggested continuous denitration process combining the denitation by formic acid and residual acid-electrolytic treatment could control continuously a feeding nitric acid of 2.0M to below about 0.1M.
