We have no doubt the fundamental way solving osmidrosis is surgical excision, and various operative technique have been introduced. Resection of the sweat glandular layer in the axillae is attactive because of certain advantages. Sensation and sweating begins to return between 6 weeks and 3 years postoperatively. For this reason, several previous reports on the resection procedure of sweat glands were inadequate because the period of follow up were too short. A follow up study using the questionnaire was done from 36 to 60 months postoperatively in the 24 cases of the patients and the following results were obtained: 1) There was no more foul odor from axillae. 2) Although there was a remarkable decrease in axillary sweating, moisture was preserved because sebaceous and eccrine glands were partially retained. 3) Axillary hairs were scanty, compared to the preoperative condition. 4) The operative scar was invisible 5) There was no motion limitation of the axillae. 6) All the patients were satisfied with the results of the operation. We can recommend the superiority of this resection procedure of sweat glands above other surgical technique with the above results.

As it is difficult to construct a micro-fluidic system composed of micro-mixers, micro-channels and/or micro-chambers in a single process, an assembly process is typically used. The assembling and bonding of micro-parts, however, introduces other problems. In this work, a virtual assembly process was developed that can be used to design various micro-fluidic systems before actual fabrication commences. In the process, the information required for the micro-stereolithography process is generated automatically. Consequently, complex micro-fluidic systems can be fabricated in a single process, thereby avoiding the need for additional assembly or bonding processes. Using the developed process, several examples were fabricated.

This study investigated the effect of the tempering before aging on the precipitation of Laves phase and mechanical properties of 10Cr-6W and 10Cr-6W-3Co ferritic heat-resistant steels. Laves phase was precipitated by aging, which increase tensile strength but decreased elongation and impact value. Toughness was rapidly decreased by the presence of the very fine disk-like Laves phase precipitated at early aging stage. Strength and impact value were decreased by tempering treatment and that is due to the increase of the particle number per unite area and to larger particle size of Laves phase. Laves phase increased by adding Co, and consequently strength was increased and elongation and toughness were decreased. (Received February 26, 2004)

Purpose : We have evaluated the outcomes of peritoneal dialysis in patients with metabolic crises caused by in born error of metabolism. Methods : There are 6 patients(8 episodes, 4 males and 2 females) who had inherited inborn errors of metabolism and were admitted to the department of pediatrics, Shoonchunhyang university hospital in Seoul from December 1991 to December 1994. The technique of dialysis is discribed, in short: A Tenckhoff catheter was inserted surgically in all patients through the lateral abdominal wall. Commerically available dialysate solutions(Peritosol, Korea Green Cross Co.) was applied to 5 patients(7 cases) with hyperammonemia. In a patient with propionic acidemia, we used a special custiom made dialysate that replaces lactate by bicarbonate. Results : 1) The mean age was 5.3 months old. There were 6 patients with 8 episodes. Six cases had Ornithin transcarbamylase deficiency. The remaining cases are Multiple carboxylase deficiency and Propionic acidemia (Table 1) 2) In 7 cases with hyperammonemia, mean levels of pre and post 24hrs peritoneal dialysis serum ammonia were 1000.2±310.9 ㎍/dl and 388.8 ±156.7 ㎍/dl at 24 hours respectively. Time on serum ammonia levels reached below 300 ㎍/dl was 88.7 ±39.6 ㎍/dl hours. 3) Four out of seven cases were a recorvert of mental status. Each episode of serum ammonia mean levels was 388.8 ±156.7 ㎍/dl after 19.7 ±5.8 hours of peritoneal dialysis (Table 3). 4) Peak serum ammonia levels of the survived group reached 1356.5 ㎍/dl, higher than the expired group of 847.5 ㎍/dl and time period of starting peritoneal dialysis after onset of the survived group was 15.5 hours earlier than the expired group of 23 hours(P>0.05)(Table 4). 5) 3 out of 7 cases of hyperammonemia died. The cause if death were 3 brain edema, 1 hyperkalemla and 1 intracranlal hemorrhage. 6) In onecase with Multiple carboxylase deficiency, serum ammonia level was normalized after 12 hours of peritoneal dialysis. The reduction of serum levels of the branched amino acid was also observed. 7) In a case of Propionic acidemia with severe metabolic acidosis, the prior serum bicarbonate level was 8 mmol/L and was increased up to 18 mmol/L by peritoneal dialysis lasting 19 hours. 8) Among 8 cases, complications of peritoneal dialysis were 5 hypoalbuminemia, 4 hyoercalcemia, 4 hyperglycemia and leakage of peritoneal dialysate. Conclusions : In cases of hyperammonemia, survival rate is 57.1%. They are showed excellant efficacy of treatment of peritoneal dialysis for metabolic crises. In a case of propinic acidemia is fastly corrected by peritoneal dialysis. But unfortunally clinical manifestations is not improved. Therefore, further studies is required with treatment of severe metabolic acidic conditions.

Objetives : In order to provide useful data tbr the further clinical studies with Korean alcohol-dependent patients, enrollment and non-relapse rates were investigated while alcohol-dependent patients wcre followed up for 24 weeks. Methods : The subjects of this study were alcohol-dependent male patients who, for the first time, visited a hospital among 3 groups of hospitals, University Hospital, General Hospital or Mental Hospital, or those who needed to be followed up after discharge from those hospitals. After assigning 12 subjects to each hospital, we investigated enrollment and non-relapse rates while cognitive-behavioral therapy and pharmacotherapy were provided. Results : 1) Forty-eight patients were enrolled and the rate of enrollment was 36.4%. The enrollment rate in the University Hospital group was 52.1%, in the General Hospital group 50.0%. and in the Mental Hospital group 10.4%. 2) In 48 patients, non-relapse rate was 27.1% at 12 week and 18.8% at 24 weeks after starting follow-up. It was 24.4% and 20.0% at 12 and 24 weeks, repectively, in the University Hospital group while the General Hospital group showed 33.3% and 16.7%, respectively, and the Mental Hospital Group showed 20.0% at both 12 and 24 weeks. Conclusion : These results provide important data for further clinical studies of Korean alcohol-dependent patients.

이동환,송창수,강경욱 울산대학교 1991 공학연구논문집 Vol.22 No.2

地面板위에 모양이 서로 다른 복수 장애물을 바람의 방향과 수직으로 배열(Side-Side)하여 액체4염화 티타늄을 관찰대상 표면에 직접 도색하여 유동장을 효과적으로 가시화 하였다. 장애물 사이의 간격이 좁아지면 틈을 통과하는 흐름은 어느 한쪽으로 傾斜진다는 특징이(Biased Flow) 확인되었고, 지면판위 박리선, Necklace Vortex, 후류등 3차원 유동장 특징이 확인되었다. Flow patterns around two-bluff bodies in side-by-side arrangements on the ground plane are easily visualized using liquid titanium tetrachloride. In two-dimensional flow field, the gap flow between two-bodies became biased to one side for closer spacing. Three-dimensional flow patterns, which have seperated regions, necklace vortices and other dynamic seperations, are dependant on the bluff-body shape and the gap-space ratio.
