Correlation between Respiratory Rates and the Degree of Bradycardia in Strabismus Surgery in Children Jong-Man Kang, M.D., Hee-Soo Kim, M.D., Chong0Sung Kim, M.D. and Myung-Kul Yum, M.D.^* Department of Anesthesiology, College of Medicine, Seoul National University, Seoul, and ^*Department of Pediatrics, College of Medicine, Hanyang University, Seoul, Korea Background: Strabismus surgery is frequent in pediatric ophthalmic surgery. Traction on the extra-ocular muscles can trigger an oculocardiac rdflex. We investigated the correlation between respiratoy rates and the degree of bradycardia to find another management for preventing oculocardiac reflex. Methods: NO premedications were administered. They were induced with thiopental and vecuronium and maintained with O_@-enflurane-N_2O. The tidal volume was 10 ml/kg. Respiratory rate of group 1 (n = 18) was fixed at 24 bpm, group 2 (n = 18) at 20 bpm, and group 3 (n = 19) at 16 bpm. We measured the mean heart rate from intubation to the beginning of surgery and defined this as the basal heart rate. We defined the lowest heart rate after traction of the extraocular muscles as the minimal heart rate. We calculated the correlation coefficient between the respiratory rate and basal heart rate, minimal heart rate, the change of heart rates and E_tCO_2. Results: There was a positive correlation between the respiratory rate and the basal heart rate, and minimal heart rate. There was no correlation between the respiratory rate and the change of heart rate. There was no difference in E_tCo_2 among the 3 groups. Conclusions: Can be increased both basal heart rate in anesthetized patients and minimal heart rate induced by oculocardiac reflex by making the respiratory rate more rapid if there is no significant difference of E_tCO_2. The oculocardiac reflex may be reduced by making respiratory rate more rapid if there is no significant influence on minute ventilation. (Korean J Anesthesiol 2001; 41: 450~454)

An 51-year-old woman presented with microscopic hematuria without protenuria for long time. Laboratory studies demonstrated the presence of red blood cells in urine, a normal serum IgM level, the absence of antinuclear antibodies, and a normal complement level. Renal biopsy revealed that some glomeruli are enlarged with endocapillary cell proliferation and a few glomeruli exhibit prominent vascular pole of the tufts and segmental increase in mesangial cell and matrix. Immunofluorescence studies demonstrated segmental granular deposits for IgM. Electron microscopy showed well-preserved foot process associated with focal effacement. Biopsy findings were consistent with IgM nephropathy. We present this case to promote understanding of the pathogenesis of IgM nephropathy. (Korean J Nephrol 2002;21(2):317-321)

Carcinoid tumors have been reported in a wide range of organs but most commonly involve the lungs, bronchi and gastrointestinal tract. Within the gastrointestinal tract, appendix is the most common location for carcinoid, followed by the distal small intestine, the rectum, and the stomach. Among these, primary involvement of the ampulla of Vater is extremely rare. We report a case of carcinoid tumor of ampulla of Vater. A 62-year-old man presented with epigastric soreness. Gastroduodenal endoscopy showed hyperemic bulging mass on ampulla of Vater and diagnosed as carcinoid tumor by histologic finding, with immunohistochemical study. In ^(111)In-octreoscan, tumor had regional lymph node metastasis, but no evidence of distant metastasis. Pancreatoduodenectomy with lymph node dissection was performed.

The cool storage system(CSS) is a specific building that is required only cooling load without heating during the whole year. CSS uses a electric energy which is very expensive and is required much amount of energy due to temperature differences between interior and ambient temperatures. The purpose of this study is to assess the energy performance of the multi-unit cooler operating control system. For the prediction of its performance, two types of test (KIER). First cell is equiped with one .are installed a t Korea Institute of Energy Research large unit cooler. and second cell consists of two small unit coolers. According to the results of experiments using these cells. the multi-unit cooler operating control system is found to be effective in energy saving and beneficial for storage due to much less deviation of temperature.

Recently we emphasize the role of construction work's supervision, which is rasing its head, for the protection of an insolvent construction and the ensurance of quality control in the lesson of the big accident of Sampung Department Store and Chonjuuam center. Government has been carrying out the Responsible Construction System to get rid of an insolvent construction at a construction site since January 1 in 1994. But it is urgent to revise systematically for early fixing of supervision system and related system according to the construction market on August in 1995. In the case of Korea, depending on making a construction we didn't experience a supervision. We must grope the revision of its system and the access to the international level. We have to reflex and revise is operation system which pass current with overseas construction market. We must diminish confusion and an unnecessary friction with over seas companies which take part in domestic construction works. Ultimately, We have improve techniques of domestic supervisor and expert supervision companies. It will contribute to the turning for the advanced system. Accrodingly I will try for early fixing of special supervision system in Korea. For this I analyzed the construction supervision system to solve. We come to the conclusion by analyzing several countries construction system USA, ENGLAND, JAPAN ect.

Background and aims : In the coronary artery disease, a rate of restenosis was much decreased by placement of coronary stent than when percutaneous transluminal coronary angioplasty has been applied, but there are still important clinical problems of restenosis. There has been many progressive studies about various factors contributed to this restenosis. So, we studied a relation between restenosis after placement of coronary stent in the coronary artery disease and many clinical factors, characteristics of stenotic lesion and procedural factors, and also assessed the restenosis rate of various coronary stents. Methods : Total 58 lesions(46 cases of patients ; man 30, woman 16) were evaluated, which has been performed a follow-up coronary angiography after 6 months (mean 188 days) since coronary stent had been placed. Various stents were implanted and assessed a relation between restenosis and many factors. Results : Of 58 lesions were target stenotic studies, there were 22 of restenotic lesions(37.9%), and the restenosis rate wes statistically significant difference in the relation with diabetes mellitus(p<0.05), group of acute myocardial infarction(p<0.05) among clinical diagnosis of ischemic heart disease(stable angina, unstable angina and acute myocardial infarction) in clinical factors and with high dilation pressure of stent(p<0.05) in procedural factors. When the rate of restenosis was evaluated among implanted stents, it was lowest in the Multilink^(®) stent and highest in the Nir Royal^(®) stent(60%). Conclusion : In this study of restenosis and various factors after placement of stents in the coronary artety disease, factors such as diabetes mellitus, group of acute myocardial infarction and a dilation pressure of stent were significant related with restenosis and the restenosis rate of Multilink^(®) stent was lowest and the highest restenosis rate was of Nir Royal^(®) stent.

Individual identification is an important part in medicolegal field especially in mass disaster. At July, 27, 1989, KAL KE-803 was crashed on landing at Tripoli International Airport, Liba. The plane was caught in fire and sixty eight Koreans were sacrified. The majority of victims were severely charred and injured. The authors examed all dead bodies and successfully identified all the cases through visual, anthropological, odontological, radiological and pathological methods including fingerprint and blood typing.
