The Actinomyces species are normal flora of oral cavity and upper intestine characterized as gram-positive, non-spore-forming anaerobic or mjcroaerophilic rods. Actinomycosis is a chronic suppurative and granulomatous disease characterized by abscess, sinus, abundant granulation and mass. The appendix is the commonly involved site among abdominal actinomycosis. Abdominal actinomycosis is often difficult to diagnose before operation because of no reliable clinical features and infrequency of the disease. We report two cases of abdominal actinomycosis which were manifested as acute appendicitis. Those were detected Incidentally tv the pathologist after routine appendectomy. Both patients were successfully treated with appendectomy followed by proper antibiotics use.

유호영,진종태,김진무 울산대학교 1991 공학연구논문집 Vol.22 No.1

SPCC강에 대한 점소성 거동의 특성을 Perzyna 점소성 모형을 기준으로 실험적으로 조사하였다. 점소성 구성방정식을 미소변형 및 유한변형이론에 맞추어 표현하고, 각 경우에 대한 물질상수 및 정적항복함수를 구하였다. 여러가지 변형율속도하에서 인장시험 결과로 부터 물질상수 및 정적항복함수를 결정하기 위한 자료처리 방안이 제시되었다. The characteristics of Visco-Plastic behaviors of SPCC steel are investigated empirically based on the Visco-Plastic model proposed by Perzyna. Visco-Plastic constitutive equations are expressed according to both infinitesimal and finite deformation theories, and material constants and static yield function are obtained in each case. A method of data regression is proposed for determining the material constants and static yield function from the results of tensile test under various strain-rate.

Nephrolithiasis is one of the most common disease seen in the Emergency Department. Among the patients who visited in the Emergency Department with acute abdominal pain, many people were suspected urolithiasis. Because of limitation of diagnostic method on Emergency Department we planned this study in order to confirm the our accuracy of diagnosis and the possibility of misdiagnosis. During 5 months from April 1996 to August 1996, the 189 patients was suspected the urolithiasis. Among this patient, 51 cases was excluded due to incomplete study. After performing P/Ex, U/A, KUB in the Emergency Department, they were followed out patients department of Urology and perfomed Intravenous Pyelogram. The sensitivity and specificity for KUB were 84.5% and 94.0%, respectively. The positive predictive value was 93.8%, the nagative predictive value was 93.8%. Diagnostic accuracy of urolithiasis in our Emergency Department is 89.1%. There was no relationship between urinary occult blood and KUB or IVP. There was no relationship between degree of occult blood and diagnosis of urolithiasis. For differential diagnosis of urolithisis, emergency ultrasound and IVP will be available. So combination of this diagnostic methods will improve accuracy and safty of diagnosis and treatment of urolithiasis.

탄성 다물체 동력학 해석 프로그램을 위한 중간 처리기 CNU_IP 개발

유진영,김성수 忠南大學校 産業技術硏究所 1996 산업기술연구논문집 Vol.11 No.1

An intermediate processor, called CNU_IP, has been developed to generate and transfer the necessary data from the commercial finite element program ANSYS to the flexible multibody dynamics program AUTODYN7, which is under development. Binary result file reading routines have been developed to extract deformation mode shapes and consistent mass matrices from the ANSYS binary result file. Using extracted deformation modes, the CNU_IP carries out inertia relief computation for the static correction mode based on the component mode synthesis theory. The program also produces lumped mass entries and lumped rotary inertia entries for the flexible body equations of motion by diagonalizing the consistent mass matrices from the finite element model of a flexible body. Various methods to generate lumped rotary inertia entries have been investigated to select the appropriate method. To show the use of CNU_IP, a flexible chassis model of a military jeep has been demonstrated to produce necessary flexible body data for AUTODYN7.

유영준,김수진 한국장애인재활협회 2011 재활복지 Vol.15 No.4

본 연구는 장애아동재활치료사업에 참여한 이용자와 치료사를 대상으로 서비스 전달과정에서 가족중심실천정도를 파악하였다. 이와 함께 가족중심실천이 장애아동 가족임파워먼트에 미치는 영향력을 분석하였다. 가족중심실천은 사회복지서비스를 제공하는 과정에서 서비스 제공기관이 어느 정도 장애인 가족의 참여와 의사결정권을 존중하고, 이를 실천 과정에 반영하는가를 의미한다. 분석결과 장애아동재활치료 사업의 가족중심실천정도에 대한 인식은 서비스 제공자가 사업에 참여한 이용자보다 유의한 정도로 높게 인식하고 있었다. 이와 함께 서비스 제공과정에서 가족중심실천정도가 높을수록 가족의 임파워먼트가 높아지는 것을 확인할 수 있었다. 따라서 장애아동 재활치료사업이 장애인 가족의 임파워먼트를 강화하기 위해서는 전문직 종사자들이 가족중심실천의 원칙과 가치를 숙지할 필요가 있으며, 이를 이용자들이 인식할 수 있도록 적극적으로 실천하는 것이 요구됨을 확인할 수 있었다. This article discusses the effect of family-centered practice on family empowerment in the disable child service bauocher. Family-Centered Practice strengthen the capacity of parents to care for and protect their children and promote the family's capacity to manage their own lives. And Family-Centered Practice is based on a set of values, beliefs and principles that recognize that families can contribute to all aspects of services through their active participation. The findings indicate that although practitioner or therapist recognized family-centered practice as important in the Disable Child Service bauocher, they only perform therapeutic services. Therefore practitioner or therapist in the Disable Child Service bauoche are required to improve the performance of Family-Centered Practice strategies and to consider the viewpoint of Family-Centered Practice's values, beliefs and principles. Fanally, Family-Centered Practice empower family by appreciation of family's values, beliefs, and by participating them as partners in decision making.

임영진,유희,강경태 울산대학교 2000 공학연구논문집 Vol.31 No.1

상용 유한요소 해석 프로그램인 MARC를 이용하여 트럭이나 소형버스의 현가 장치로 많이 쓰이는 겹판스프링을 모델링하고 판사이의마찰에 의해 생기는 하중-변위 히스테리시스 곡선을 재현하여 겹판스프링의 특성을 해석하였다. 또한 실제 겹판스프링에 스트레인시스 곡선을 재현하여 겹판스프링의 특성을 해석하였다. 또한 실제 겹판스프링에 스트레인 게이지를 부착하여 각부분에서의 변형률값을 구하고 유한 요소 해석 결과와 비교하였다. 유한요소 해석에서의 하중에 따른 변위값은 거의 유사한 결과를 나타냈지만 변형률에서는 많은 차이를 보였다. 그러나 유한요소 해석에서의 하중-변위 곡선과 시험에서의 하중-변위곡선은 마찰력 차이는 있었지만 정스프링 정수값은 거의 같음을 확인할 수 있었다. Characteristics of leaf spring was analyzed by using commercial finite element analysis program MARC and the load-displacement hysteresis curve was successfully simulated which is occurred by interleaf friction. Compression test was performed to practical leaf springs for trucks from which load-displacement and load-strain results were obtained. It is found that load-displacement hysteresis curve and static spring rate were in good agreement with FEM results. However, meaured strain values and friction force were different from those of FEM results.

이유선,정진옥,박용규,박형서,노상필,정승현,김정희,이재환,최시완,성인환 충남대학교 의학연구소 2003 충남의대잡지 Vol.30 No.2

급성 심근염환자에서 발행한 완전 방실차단을 영구 심장박동 조율기로 치료한 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Myocarditis, an inflammatory process involving the myocardal wall, may be caused by most infectious agents. Irrespective of its etiology, it presents commonly with evidence of heart failure, hypotension, and various electrocardiographic abnormalities. Patient with myocarditis may be asymptomatic or may have a rapidly progressive fatal disease. Medical management of patients with myocarditis includes specific therapy for underlying infection and control of the complication of myocarditis such as congestive heart failure and arrhythmia. Recently we had experienced myocarditis with complete atrioventricular block in 37-year-old man. Although he had shown complete recovery of heart failure, he had shown complete atrioventricular block, so we inserted permanent pacemaker. We report it with review of the literature.
