An imaginative innovation to shorten hospital stays as a means to reduce patient charges, is out-patient surgery. This procedure also minimized the inconvenience and disruption of the family unit, reduced the opportunities for cross-infection, and freed hospifal beds for the more serriously ill patienta Since the concept of out-patient surgical service was organized, managed, and performed in the Hanyang Medieal Center, we had experience of 132 ambulatory anesthetics during the last two years (from Jan. 1974. to Dec. 1975 ). The results are summarized as follower 1. Preanesthetic examination should be routinely cheeked with Hb., Hct., urinalysis and chest x-ray. 2. Premedication should be administered preanesthetically, atropine sulfate intravenously. 3. ASA class 1 patients should be rhnsen fnr short (less than 1 hour) procedures. 4. Anesthesia is induced with Epontol+S.C.C. and maintained with Halothane+N2O+O2. 5. We suggest that ambulatory anesthesia should be more carefully planned, organized, and managed.

육성돈 단백질 사료로서 원산지가 다른 대두박과 이들 원료에 어분을 3%씩 대체하여 배합한 한국산 대두박(KSBM), 중국산 대두박(CSBM), 인도산 대두타(ISBM), 한국산 대두박 + 어분(KSF), 중국산 대두박 + 어분(CSF) 및 인도산 대두박 + 어분(ISF)의 6처리구를 공시하여 급여한 육성돈의 중체량, 사료섭처량 및 사료효율을 구명하고자 60일간의 사양시험을 실시하였으며, 그 결과를 요약하면 다음과 같다. 1. 원산지별 대두박의 총 아미노산 함량은 한국산 대두박이 34.7%로서 다른 대두박에 비하여 높았으나 중국산 대두박은 25.3%로서 가장 낮았다. 어분의 총 아미노산 함량은 54.7%로서 대두박보다 현저히 우수하였다. 대두박과 어분의 필수아미노산 중에서는 Arginine, Leucine 및 Lysine 함량이 높았고 비필수아미노산 중에서는 Aspartic acid와 Glutamic acid 함량이 높았다. 2 총 중체량과 1일중체량은 원산지별 대두박간에는 ISBM구(36.6 및 0.61 ㎏)가 타처리구에 비하여 높은 경향이였으나 이들 대두박의 일부분을 어분으로 대체한 ISF구 타처리구와 비슷하였다. 3. 총 사료섭취량은 원산지별 대두박간에는 ISBM구(82.9㎏)가 타 처리구에 비하여 낮았으나 이들 대두박의 일부분을 어분으로 대체하였을 때 타처리구 에 비하여 ISF구(89.1㎏)가 높은 경향을 나타내었고, 일당 사료섭취량과 사료효율은 각각 1.38∼1.48 및 2.23∼2.48 범위로서 처리구간에 차이가 없었다. This studies were performed to compare the effects of various prorein sources such as Korean soybean meal (KSBM), Chinese soybean meal (CSBM) and Indian soybean meal (ISBM), and Korean soybean meal + Fish meal (KSF), Chinese soybean meal + Fish meal (CSF) and Indian soybean meal + Fish meal (ISF) replaced 5 percent of their soybean meals by 3 percent of fish meal on the body wight gain, feed intake and feed efficiency of growing pigs. A total of 108 pigs with average body weight of 20 ㎏ were assigned in Completely Randomized Design (6 × 3 × 6) for feeding trial. The results obtained are as followed. 1. Total amino acid contents of soybean meals according to origin were the highest in KSBM (34.7%), the lowest in CSBM (25.3%), and those of fish meal were higher than those of soybean meals. Of the indispensable amino acids of soybean meals and fish meal, arginine, lysine and leucine contents were higher, and of the dispensable amino acids, aspartic acid and glutamic acid were higher than other amino acid contents. 2. Total and daily body weight gain of pigs fed diets without addition of fish meal were slightly better in pigs fed ISBM diet (36.6 and 0.61 ㎏) than in pigs fed other diets without significant differences, but those of pigs fed ISF diet were similar to those of pigs fed other diets with addition of fish meal. 3. Total feed intake of pigs fed diets without addition of fish meal were lower in pigs fed 1SBM diet (82.9 ㎏) than in pigs fed other diets, but that of pigs fed ISF diet (89.1 ㎏) were higher than in pigs fed other diets with addition of fish meal. Daily feed intake and feed efficiency of pigs fed six different diets with or without fish meal were in the range of 1.38∼1.48 ㎏ and 2.23∼2.48 without significant differences.

김재황,유성오,송영민,박성진,고영두 한국영양사료학회 1999 韓國營養飼料學會誌 Vol.23 No.6

육성돈 단백질 사료로서 원산지가 다른 대두박 및 이들 원료에 어분을 3%씩 대체하여 배합한 한국산 대두박(KSBM), 중국산 대두박(CSBM), 인도산 대두박(ISBM), 한국산 대두박 + 어분(KSF), 중국산 대두박 + 어분(CSF) 및 인도간 대두박 + 어분(ISF)의 6처리구를 공시하여 생체내 아미노산 이용율을 루명하고자 (T-cannula가 장착된 6두의 돼지를 6 × 6 Latin 방각법으로 배치한 후) 대사 시험을 실시하였으며, 결과를 요약하면 다음과 같다. 1. 외관상 Fecal 아미노산 소화율은 모든 처리구 중에서 ISBM구가 다소 높았고 CSBM구가 낮았으나 거의 비슷한 경향이였으며, 대두박의 일정량을 어분으로 대체하므로서 다른 어분 대체구보다 중국산 대두박에 어분을 대체한 CSF구의 소화율이 상당히 증진되었다. 각 처리구의 필수아미노산중에서는 arginine, histidine 및 methionine의 소화율이 높았고 비필수아미노산 중에서는 glutamic acid의 소화율이 높았다. 2. 외관상 ileum 아미노산 소화율은 모든 처리구 중에서 KSBM구가 86.6%로서 가장 높았고 CSBM구가 80.1%로 낮았으나 대두박의 일정량을 어분으로 대체하므로서 다른 어분 대체구보다 중국산 대두박에 어분을 첨가한 CSF구의 소화율이 증진되었다. 각 처리구의 필수아미노산 중에서는 arginine, histidine 및 methionine의 소화율이 높았고 비필수아미노산 중에서는 glutamic acid의 소화율이 높았다. 3. Fecal 아미노산 소화율에서 ileum 아미노산 소화율을 뺀 차이로서 가장 큰 차이는 CSBM 및 KSF구에서 나타났으며, 각 처리구의 필수아미노산 중에서 가장 큰 차이는 KSBM, ISBM, KSF 및 CSF구에서는 threonine이였고, CSBM구에서는 valine이며, ISF구에서는 phenylalanine이였다. 비필수아미노산 중에서 가장 큰 차이는 KSBM, CSF 및 ISF구에서는 glycine이였고, CSBM, ISBM 및 KSF구에서는 proline이였다. This studies were performed to compare the effects of various prorein sources such as Korean soybean meal (KSBM), Chinese soybean meal (CSBM) and Indian soybean meal (ISBM), and Korean soybean meal + Fish meal (KSF), Chinese soybean meal + Fish meal (CSF) and Indian soybean meal + Fish meal (ISF) replaced 5 percent of their soybean meals by 3 percent of fish meal on the amino acid digestibility of growing pigs. Six pigs fitted with a simple T-cannula were assigned in 6 × 6 Latin Square Disign for digestion trial. The results obtained were as followed. 1. Apparent fecal amino acid digestibility of the ISBM was a little higher than any other treatments, and digestibility of the CSBM was the lowest of all the treatments, and the digestibility of the CSF treatments which replaced a fixed quantity of the CSBM by fish meal was grown much more than the others. The digestibility of Arginine, Histidine, and Methionine were higher on the essential amino acids of each treatments, and the digestibility of glutamic acid was higher on the non-essential amino acids. 2. Apparent Ileum amino acid digestibility of KSBM(86.6%) was the highest of all the treatments, but that of CSBM(80.1%) was the lowest, As replacing CSBM by a fish meal, the digestibility of CSF was improved. The digestibilities of Arginine, Histidine, and Methionine were higher on the essential amino acids, and the digestibility of Glutamic acid was higher on the non-essential amino acids. 3. When fecal amino acid digestibility was subtracted by Ileum amino acid digestibility, the highest difference appeared at CSBM and KSF. The highest difference on the essential amino acid of each treatment was that Threonine is KSBM, ISBM, KSF and CSF, Valine is CSBM, phenylalanine is ISF. The highest difference on the non-essential amino acid was that Glycine is KSBM, CSF and ISF, proline is CSBM, ISBM and KSF.

In the 1st two years (Frcm April 1975 to March 1977), we have had experience with 15 surgical infant patients undergoing general inhalation anesthesia with the $quot;Loasco$quot; Infant Ventilator. The Locsco$quot; Infant Ventilator is designed for the ventilation of neonates and infants on the lines of an open sysern with a gas mixture of air-oxygqn or oxygen-anesthetics. However we used it with a gas mixture of halothane-N2O-oxygen, This study was undertaken to evaluate the value of ventilatory support with the Loosco$quot; lnfant Ventilator auring general inpa!ation anesthesia for 15 surgical patients ivhose age was less than 2 years of age. The blood gas analysis showed slight underventilation cnmbined with metabolic acidosis during the first 15 minutes, in which respiratory frequency was set at 30 times per minute, but the ventilation was gradually improved by inciease in respirataey frequency to 35 times per minute during tlie lost 20 ninute. In this study, ive corsiderec. the irnportant tactors ivhich inftuenced the value of the blood gas analysis. Not only caveful anesthetic niaoagement to keep the airway and to corvect cardiovascuiar clerangeineht, but also frequent and repeated blood gas analysis and its aeeurate interpretation were stressed for using the $quot;Loosco Infant Uentilator during pediatric general anesthesia.

Since 1929, the iodine compounds were used intravenous pyelogram by the Swick, it was accepted for the use of intravenous pyelogram in the worldwide. Nevertheless, it has several minor and major side reactions, also it has been used to IVP or cholecystography at X-ray room without prepared for side reaction or resuscitation. We have experienced a case of sever hypersensitivity reaction with the urografin during IVP at X-ray room. Here, we review with the several articles including its etiology, symptoms and treatments. Especially, we classified the mild and severe reactionsby David and Frederick from Table 1 Table 6. Furthermore we considered that t is necessary to prepared the resuscitating instruments during IVP with urografin under local or general anesthesia.

Al 함유 13%Cr 스테인리스강의 표면 질소침투 열처리에 미치는 첨가원소 탄소의 영향 : 13%Cr 스테인리스강의 고질소 표면침투 열처리

성장현,주동원,김기돈,유대경,박진욱 한국열처리공학회 2000 熱處理工學會誌 Vol.13 No.3

This study aims to investigate the effect of carbon content on the surface nitrogen permeation of 13%Cr-1.8%Al alloyed stainless steels. The surface nitrogen permeation was performed at 1050℃-1200℃ in the 1㎏/㎠ nitrogen gas atmosphere. The nitrogen permeated surface layer of the specimen containing 0.03%C consists of AlN, martensite and retained austenite phases, while the surface layer of the specimen containing 0.14%C appears the AlFe₃C_x phase including former three phases. The specimen containing 0.14%C shows lower total case depth than that containing 0.03%C at the nitrogen permeation temperatures of 1050℃ and 1100℃, while the total case depth of the specimen containing 0.14%C is remarkably increased at the temperature of 1150℃ and 1200℃ due to the increase in the retained austenite content. Martensitic phase, AlN and AlFe₃C_x precipitate of the nitrogen permeated surface layer cause to increase the surface hardness of 550∼600Hv.

This study was carried out to find fundamental conditions for effective solvent extraction of Ti and Fe components from leaching solution of reaction product of (NH₄)₂SO₄ and titaniferous magnetite ore. In experiment of solvent extraction of Ti and Fe components, new aqueous phase which contains only Ti(IV), Fe(III) was used instead of leaching solution of sulfation product. The extraction of Ti(IV) and Fe(III) components from aqueous phase with D₂EHPA (Di-2-ethyl hexyl phosphoric acid)-kerosine system was carried out as function of concentration of extractant in the organic phase, pH of agueous phase and shaking time. The maximum value of separation factor(β) was 102.6 at 0.05 M D₂EHPA, aqueous phase pH 1.0, and 30 min was sufficient for the condition of shaking time. In stripping of Ti and Fe components from organic phase; the higher temperature and more concentration of H₂SO₄ increased the stripping percent of Ti and Fe components and the stripping percent of Fe was always higher than that of Ti. In separation process of Ti and Fe components, when 2 step stripping process was used, 93.7%, 99.5% Ti and Fe components was obtained respectively. While, 3 stage continuous countercurrent process was used, 96.3%, 84.7% of Ti and Fe components was obtained respectively.

유영홍,이철태,박용성,김재용 고려대학교 공학기술연구소 1985 고려대학교 생산기술연구소 생기연논문집 Vol.21 No.1

The reactions between raw ilmenite and NH₄Cl, and between alkali(NaOH) fritted ilmenite and NH₄Cl, were experimentally investigated in order to find the possibility of NH₄Cl, being an alternative chlorine source. By comparing the experimental results, NH₄Cl, was a good alternative chlorine source for the chlorination of alkali frilled ilmenite. The optimum conditions for alkali fritting were caustic ratio: 1.0, fritting temp.: 800℃, holding time : Ih and for the chlorination of alkali frilled ilmenite were reaction temp. : 325℃, weignt ratio of NH₄Cl, to ilmenite: 5.0, reaction time : Ih, N₂ gas flow rate : 30 ㎤/min. Under above mentioned conditions, the conversion of iron in ilmenite to iron chloride was 88.9% and the content of TiO₂ increased from 55.5% to 88.3%.

김완식,박동호,황호성,유희구 대한마취과학회 1976 Korean Journal of Anesthesiology Vol.9 No.1

We have experienced a case of incompatible blood transfusion during general anesthesia in which 300ml of improperly typed blood were tranfused. Upon discovery of the error, the tranfusion was discontinued and the patient was immediately, carefuliy and aggressively treated with proper fresh blood, plasma expander(Rheomacrdex-D), fluids(Hartmanns solutipn and 10% dextrose in water) and drugs (Solu-Cortef 300 mg, furosemide 400 mg, 20% manitol 500 ml, digoxine 0. 5 mg, morphine 15 mg). The free hemoglobin in the plasma and urine and blood gas of the femoral or radial artery were rnonitorecl throughout the resuscitative procedure. It is felt that accidental incompatible blood transfusion of more than 300 ml should be preventable and that the patients life may be saved without serious complications with imme-diate and proper management.

Although the acupuncture is not accepted medical therapeutic method in Korea, the author has been undertaken to treat various conditions of pain in an pain clinic at HANYANG University Hospital during 11 months from 1975 to 1976 to 62 patients who had not responding to conventional treatments such as medication, nerve block, physiotherapy and psychotherepy .etc. At the result of the electrical Acupumcture stimulation, 17 patients (27.4%) showed marked improvement, 21 patients (33. 9%) showed improvement and 21 patients (33. 9%3 transient improvement. The total confidence showed O8 patients (61. 3%), furthermore the longterm results of these follow up study will be carried continuously with the questioners within 6 months. And also the mechanisms of the stimulation produced analgesia reviewed with the recent reported several literatures. In conclusion, acupuncture can be used to relief of various pain for which coventional trea tments are less effective. Acupuncture is relatively easy to learn and to practice by the acquisi- tion of minimal knowledge of the technique.
