The formation or reconstruction of an auricle is one of the most difficult operations in plastic and reconstructive facial surgery. The difficulties of its reconstruction include delicate structures of the ear, extremely thin skin, difficulty in color match, and springing effect of the thin supporting skeleton consists of cartilage with its peculiar recesses and bumps. Even though, several techniques have been using for auricular reconstruction, it would be difficult to obtain an ideal auricle. Furthermore surgeon's talent and sufficient practice might be needed for a satisfactory result. We attempted auricular reconstruction using negative auricular plastic mold in 10 white rabbits in order to pursue a simple and satisfactory method. Diced cartilage chips were filled into a subcutaneous pocket placed in the negative auricular mold. Mild negative pressure was maintained in the space between the cartilage-subcutaneous tissue-skin complex and mold for two months. The results were as follows: 1.An ideal shaped suitable supporting skeleton was newly formed and the fabricated new auricle had a near normal appearance. 2.Under the microscopic examination, the diced cartilage chips have conglomerated together to form a solid skin - connective tissue - cartilage framework and evenmore matured chondrocytes were noted.

윤석준,양창국,한홍무 大韓神經精神醫學會 1999 신경정신의학 Vol.38 No.5

연구목적 : 혈액투석요법을 받는 말기 신부전증 환자들은 불안이나 우울 등의 심인증상 외에도 여러 가지 수면장애를 호소할 수 있다. 말기 신부전증 환자에서 심인증상과 수면장애가 많을수록 삶의 질에 장애를 초래하며 혈액투석요법 도중 탈락이 높다. 저자는 본 연구에서 혈액투석요법 중인 환자의 우울, 불안 및 수면장애 등을 조사하여 향후 환자가료에 활용하고자 하였다. 방 법 : 부산시내 4곳의 혈액투석요법기관에서 혈액투석요법을 받는 말기 신부전증 환자 153명(남 87, 여 66)과 정신적, 신체적으로 건강한 동아대학교병원 행정직원 및 의과대학 학부모 113명(남 58, 여 55)을 대상으로 구조화된 면담과 자기평가척도를 실시하였다. 연구도구는 저자 등이 본 연구에 알맞게 개발한 인구통계학적 자료를 포함한 수면관련 설문지, 우울증 자가평가 척도인 Beck Depression Inventory(BDI), 불안 자가평가 척도인 State-Trait Anxiety Inventory(STAI)를 이용하였다. 결 과 : 환자군이 대조군에 비하여 신체증상 및 심인증상을 더 많이 호소하였고(p<0.05), 수면관련 불편을 더 많이 나타내었다(p<0.001). 환자군의 BDI 평균은 22.9로 대조군의 11.2보다 유의하게 높았다(p<0.001). BDI 점수를 기준으로 볼 때 남자환자 64명(74.7%), 여자환자 47명(71.2%)은 우울증군에 속하였다. STAI 평균 점수는 두 군간에 유의한 차이가 없었다. 환자군은 대조군에 비하여 입면잠복기와 수면 중 깨어 있는 시간이 더 길었고, 낮 동안의 졸리움 등 수면관련 불편을 더 많이 호소하고 있었다. 또한 환자군은 불면증(65.4%), 하지불편증후군(46.4%), 악몽(27.3%), 주기성사지운동장애(23.5%), 수면 식사장애(18.3%), 야경증(14.4%) 등을 유의하게 더 많이 호소하고 있었다(p<0.05). 결 론 : 혈액투석요법을 받고 있는 말기 신부전증 환자들은 대조군에 비해서 신체적, 심인적 증상을 유의하게 더 호소하고 불면증을 포함한 다양한 수면장애를 동반하고 있다. 또한 이들 사이에 높은 상호관계가 있는 바, 이는 혈액투석요법 증인 환자들에서 신체적 증상 및 심인적 증상뿐만 아니라 수면장애에 대한 치료적 접근이 필요함을 시사한다. Objectives : Psychological distresses and complaints in sleep, in addition to physical distresses such as pruritus and bone pain, are common in patients with hemodialysis. The purposes of this study were to investigate 1) the severity of physical distresses, 2) the severity of depression and anxiety, 3) the sleep disturbances, and 4) the correlation of the above variables in patients with hemodialysis. Methods : The patients with hemodialysis(male 87, female 66) and controls(male 58, female 55) completed a self-administered questionnaire package, which included Beck Depression Inventory, Spielberger's State-Trait Anxiety Inventory, and questions characterizing the reported sleep problems and quantitating the severity of the self-perceived physical and psychological conditions with linear visual analogue scales. Results : The results indicated that patients with hemodialysis complained of more physical distresses, more depressed mood, and more sleep disturbances suggesting insomnia, restless legs syndrome, periodic limb movement disorder, nightmare and obstructive sleep apnea syndrome, etc. There were significant positive correlations of physical distresses, depressed mood and sleep disturbances. However, there were no significant differences in state and trait anxiety between both groups. Conclusions : The authors suggest that the quality of life in patients with hemodialysis

앵커는 그 형식에 따라 힘을 받는 기구가 달라진다. 본 연구에서는 인장형과 압축형으로 분류되는 마찰형 앵커의 저항특성 및 기구를 분석하였고, 또한 압축형 앵커의 내하체 압축시험결과를 이용하여 압축형 앵커 내부 그라우트의 포아송 효과를 분석하여 계산식을 제안하였다. 압축형 앵커의 특성을 요약하면 다음과 같다. (1) 압축형 앵커가 인장형 앵커보다 인발시 진행성의 영향이 적은 것으로 밝혀졌다. (2) 압축형 앵커는 인발시 그라우트의 포아송 효과로 인해 주면마찰저항이 증가한다. The resistance mechanism of anchor changes according to the types of anchor. Friction anchor is classified into tension and compression types. In this study, the characteristics and mechanism of pullout are analysed, through compression test results of anchor body grout. The characteristics of compression anchor are summarized mainly as follows : (1) The effect of progressive failure of compression anchor body are much smaller than those of tension anchor during pullout of anchor ; (2) The skin friction resistance is increased by poisson effect of grout (anchor body) during pullout of compression anchor.

This paper is based on an experiment analysing the stress corrosion cracking behaviour of welding specimens compared to that of non-welding specimens of STS 304 HP stainless steel in corrosion solution. As a corrosion condition, stainless steel has been known to be the most fragile in a solution of 42% MgCl₂heated to the boiling point, therefore the experiment was carried out in this condition. The experiment was carried out with argon gas TIG welding specimens and non-welding ones made of stainless steel plates, thickness 2mm, by tensile force. At this time, the tensile force was taken to be the value of the yield strength of the tensile test specimens divided by the safety factor of 3.0 to 3.5, 4.0, 4.5, and 5.0. In this paper, the relations between Time of Initial Crack, Time of Failure, Time of Final Fracture and Crack Propagation Length were investigated and then plotted. Furthermore, the relations between Stress Intensity Factor K proposed by Irwin and the Time of Initial Crack, the Time of Failure, the Time of Final Fracture were calculated and plotted. At the last, all the relations plotted were expressed to normal equations by computer, and the equations were used to analyse the data obtained in the experiment. The conclusions obtained in this study are as follows: 1. Welding materials, compared with non-welding ones, as the Time of Initial Crack, the Time of Failure, and the Time of Final Fracture were generally very fast, appeared to be a phenomenon of unstable brittleness fracture. 2. Non-welding materials, compared with welding ones, as the safety factor was larger or the working stress was smaller, appeared to be a phenomenon that the longer had had greater durability. Therefor, welding materials must be considered enough to be used in heate affected and stress corrosion atmosphere. 3. The normal equations of the Time of Initial Crack and the variation rate to the same Stress Intensity Factor K are as follows: (A) Non-welding T =259702.4-5451.2 K+28.386 K² T = -5451.2+28.386 K (B) Welding T= -332.693+28.043 K-0.211 K² T' =28.043-0.211 K here, T; Time of Initial Crack, T'; Variation Rate of Time of Initial Crack to Stress Intensity Factor K, K ; Stress Intensity Factor.

대동물 임상에서의 침술마취의 적용

Acupuncture is used to treat pathological conditions and to prevent pain from arising. The pathological conditions that can be treated can be painless or painful conditions. Acupuncture analgesia (AA) is a specific form of acupuncture; the stimulation of the acupuncture points must be strong and long (about 15 to 30 minutes) before a local or general analgesia or hypalgesia will develop. Development of modern AA began in the late fifties. Effectiveness of acupuncture in alleviation of pain was quickly noticed and brought to the medical researchers and surgeons. Through their diligent pursuit, AA has been established as a viable alternative for relief of pain and substitution of conventional anesthesia. In veterinary medicine. early successful applications of AA to surgery of domestic animals were reported in the late sixties. Local or regional anesthesia is often preferred to general anesthesia in cattle. Acupuncture was effective in inducing analgesia. Regional electroacupuncture analgesia is potentially useful for standing surgeries in cattle. Some standing surgeries may be easily accomplished using electroacupuncture anesthesia.
