불연속 변형해석은 에너지 최소화원리를 이용하여 전체 행렬을 구성하는 유한요소법과 개별블록의 대변 위를 모사할 수 있는 개별요소법의 장점을 모두 가지고 있는 해석법이다. 이 연구에서는 불연속 변형해석에서 해석결과에 문제점이 있는 접촉문제를 개선하는 시도로써 불연속 변형해석에서 정의하는 접촉 중 선-선 접촉을 해석하는 새로운 기법을 적용하였다. 이를 위해 접촉쌍의 개념을 이용하여 새로운 7 가지의 선-선 접촉의 상태를 정의하고 이에 따른 새로운 전단거동 결정 방법과 개폐수렴반복해석에서의 수렴조건, 접촉찾기 등의 세부알고리듬을 제시하였다. 또한 블록간의 접촉에 의해 작용하는 마찰력을 기존의 점하중 형태에서 선하중의 형태로 개선하는 식을 유도하여 새 알고리듬에 적용하였다. DDA (Discontinuous Deformation Anlaysis) is one of the latest numerical analysis which has merits of both FEM and DEM. In this research, a new edge-to-edge contact algorithm was applied on DDA. With adoption of new edge-to-edge contact state definition, sub-algorithm was improved about open-close iteration, contact state judge, contact detecting, and friction forces acting on joints. Newly applied DDA was verified based on two different cases. The DDA results show good agreement with numerically predicted one.

This thesis deals with improvements plans of living space in a domestic juvenile reformatory. Juvenile reformatory is not only just facilities for detention, but also curing, protecting and educating facilities. Through analyzing the problem of domestic juvenile reformatory and case study of advanced country, The purpose of this thesis intends to suggest the planning direction and improvement direction of architecture in domestic juvenile reformatory. It will also help to show valid architectural types and facilities standard when it build, build an extension and remodel

Luis Barragan의 후기건축에 나타난 지역주의 표현경향에 관한 연구
이용재,이정훈,김희규,문영삼 순천향대학교 교수학습개발센터 2005 순천향 산업기술연구소논문집 Vol.11 No.1
The purpose of this study is to define the architectural expression of regionalism in the late period of Luis Barragan, the representative architect of Modernism in Mexico. The view point of architectural expression, the essential quality of regionalism be related to the sensitivity, passionate, and purity. We select the works of L. Barragan in the late period : Barragan House(Tacubaya, 1947), Chapel for the Capuchinas(Tlalpan, 1952) and Gilardi House(Tacubaya, 1976). The result of this study shows that the architectural expression of regionalism on the his works in the late period are the passionate sensitivity, regional commonness and human being experience in Mexico.

Air can be used as a carrier for volatile agent, ether, with a clear airway, normal pulmonary function and normal oxygenation. In 1858 John Snow, the Father of British Anesthesia stated in his book on Chloroform and Other Anesthetics that he believed it to be almost impossible for death to occur from ether administered with ordinary intelligence and attention. Today ether is probably still the safest anesthetic drug we possess. Ether is cheap and easily obtained; with controlled respiration 3% is adequate. Recovery smooth and rapid. Vomiting may be no different from other agents. Most machines depend upon cylinders of oxygen and other gases, and there are difficulties of refilling cylinders and the cost of transporting them. In such circumstances the E.M.O. Inhaler, allowing ether to be vaporized in known concentrations in air, has many advantages as an alternative to the open method administration. From all types of patients chosen at random 22 patients were studied for ether-air anesthesia. Anesthesia was induced with intravenous thiopental and subsequent endotracheal intubation was performed within 30 seconds with the aid of intravenous succinylcholine. SatO₂, PaO₂, pH, and Base E. were measured 3 times during pre-anesthesia, immediately after the intubation, and post-operatively by Radiometer, using the oxy-hemoglobin dissociation curve and the Siggard-Anderson alignment nomogram. Vital signs were recorded every 5 minutes. It is the purpose of this paper to present this series of 22 anesthetics by the use of the E.M.O. Inhaler with air and to discuss the possibility of hypoxia, advantages and limitations that became apparent. The results obtained may be summarized as follows. 1. It is essential that endotracheal intubation by carried out rapidly and that everything necessary be ready and immediately at hand before starting the anesthetic. 2. In all patients ventilated room air during anesthetic induction, no significant decreases of PaO₂ and SatO₂ were observed immediately after the endotracheal intubatio. 3. The duration of any period of complete apnea inflicted on the patient must be carefully controlled. 4. 100% oxygen prevented the possibility of hypoxia on extubation after all the reflexes had returned. 5. Ether-air anesthesia is recommended without hesitation for use where economy and portability of anesthetic machine are needed.

A review was made four cases for intraoperative or immediate postoperative cardiac arrest which occurred during the period from Jan. 1. 1980 to May 31. 1981 and resulted in dealth. The probable causes of death were; Case Ⅰ: inadequate monitoring, hemorrhage, body fluid loss, lengthy operation and sepsis Case Ⅱ: untoward effect of succinylcholine or an underlying cardiac problem Case Ⅲ: cardiac failure due to cadiopulmonary dysfunction cased by kyphoscoliosis Case Ⅳ: peripheral circulatory failure due to massive hemorrhage

Recently the influence of respiratory depression, hypercarbia and hypoxia on the intracranial pressure during general inhalation anesthesia has been strongly stressed. The study was taken to determine quantatively the effect on the cerebrospinal fluid pressure in dogs. 1) CSF pressure was determined during anesthesia via cisternal puncture with direct water-manometer and polygraph recording. 2) The changes in blood pressure, pulse rate and temperature with 0.5% halothane were observed. 3) CSF pressure was apt to rise within 30 minutes with halothane but later It gradually returned to normal or decreased slightly. This was associated with little changes or with slight rise in central venous pressure. 4) This emphasised factors related to good anesthetic technic in neurosurgery. it is recommended that preoxygenation before the induction period should be done in the administration of halothane.
