In software industry, coexist the software crisis occurring continuously with methodologies and tools for overcoming it. Since 1980's, software reuse and object-orientation have been hot issues in software engineering. Object-oriented methodology can meet user's need concentrating on convenience of development process. By dealing with software product at the component level and by focusing on arbitrarily abstract description of component, software reuse allows user to deal with minute detail. Also, by dealing with software design at the architecture level, it supplies the automation principle of what must be taken in construction process. By hand, in distributed object environment, we can produce the economical software by accessing the data from different and various repository and sharing the data with different user because it support to development the client/server program and integrate existing systems in heterogeneous environment. We implemented the MT-views to utilize the reuse effects as reuse prototyping system or supporting including retrieval, understanding and rebuilding tools based on source code, documentation and etc., using CORBA on distributed object environment.

Hepatitis A is a mild, self-limiting disease of the liver, critical complications of which, such as acute kidney injury, are rare. Two cases of patients with acute hepatitis A who had an acute renal failure complication are reported herein. The first case is that of a 30-year-old man who showed up at the author’s hospital complaining of fever and myalgia. His laboratory tests upon his admission showed 9,520 lU/L of aspartate transaminase, 5,600 lU/L of alanine transaminase, 31.9 mg/dL of blood urea nitrogen, and 5.5 mg/dL of creatinine, and he was positive for the Anti-HAV IgM antibody. Upon his admission, supportive treatment was started, which included fluid therapy. The laboratory tests on the next day showed 53 mg/dL of blood urea nitrogen, 9.9 mg/dL of creatinine, and lower urine output per day. Renal replacement therapy was performed only once. A renal biopsy was performed and the result was Acute Tubular Necrosis (ATN). The patient recovered from acute renal failure without sequela. In the second case, a 35-year-old man complained of fever and abdominal pain. His laboratory tests upon his admission showed 8,570 lU/L of aspartate transaminase, 4,510 lU/L of alanine transaminase, 16 mg/dL of blood urea nitrogen, and 1.19 mg/dL of creatinine, and he was positive for the Anti-HAV IgM antibody. He experienced acute renal failure and recovered after two-time renal replacement therapy. The result of the renal biopsy was Acute Tubular Necrosis and C1q nephropathy.

The average tail length of field mice was 78.2mm in Apodemus agrarius coreae, 95.23mm in Apodemus speciosus peninsulae, 35.0mm in Clethrionomys rufocanus regulue. 10. The average ear length of field mice was 14.3mm in Apodemus agrarius coreae, 15.77mm in Apodemus speciosus peninsulae, 14.0mm in Clethrionomys rufocanus regulue. 11. The breeding period of field mice was between March and July in pusan area. 12. average fetal number of field mice was 3.0 in Apodemus agrarius coreae, 4.8 in Apodemus speciosus peninsulae, and 4.5 in Crocidura suaveolens shantungensis.

견인골 신장술은 막내골화를 유도하는 조직 공학으로, 두개안면기형영역에서 치료는 지난 10년간 지속되었다. 본 연구는 하악지를 절단한 후 구강내 견인장치를 사용하여 안모 비대칭을 치료한 증례이다. 안모 비대칭 환자를 치료하는데 섬세하게 견인골 신장술을 이용하면 성장기와 성장이 끝난 환자에게서 효율적인 치료방법으로 생각된다. Distraction osteogenesis is a well estabilished procedure of membraneous hone formation and has been used to correct craniofacial deformities in dentofacial orthopedic surgery area for decades.

Amyloidosis is a disease resulting in deposition of amyloid in the body. The disease can be either primary or secondary. The amyloidosis of urinary bladder is more usually affected by primary amyloidosis and also very rare. The patient with primary amyloidosis of the bladder usually presents with gross hematuria. The amyloidosis resembles bladder cancer in cystoscopy. It can be confirmed by biopsy. The treatment consists of medication (e.g., steroid, antitumor agent, cholchicine, DMSO) and/or transurethral resection. The standard treatment is mephalan and prednisolone. A 49-year-old man complained of recently developed gross hematuria without abdominal pain. We examined urinary bladder cystoscope for gross hematuria. It revealed small bulging mass on trigone are a of bladder. Therefore we did bladder biopsy. Finally, it revealed bladder amyloidosis. The patient was improved by medication (mephalan 2mg and prednisolone 1 mg/kg po daily). We report an unusual case of amyloidosis involving bladder.

본 연구에서는 변성 폴리페닐렌 옥사이드(Modified Polyphenylene Oxide; MPPO) 폴리머 소재에 대하여 단축 인장 시험을 통해 기계적 물성을 측정하였다. 이를 바탕으로 MPPO의 기계적 거동을 기술하는 수정된 2층 점소성모델을 적용하여 유한요소해석을 통해 재료 상수에 대한 파라미터 분석을 수행하였다. 이를 통해 재료 모델에 유의한 재료 상수를 결정하고, 중심합성계획법을 이용해 전산실험계획을 수립하여 시험과 해석 간의 하중과 변위에 대한 평균제곱근오차를 산출하였다. 이어 오류 역전파 인공 신경망으로 재료 상수(입력)와 평균 제곱근 오차(출력) 관계에 대한 대리 모델을 생성하였다. 재료 상수 최적화 문제를 정식화하고 비 지배 분류 유전알고리즘-II를 이용하여 재료 상수에 대한 최적 해를 산출하였다. 이를 검증하기 위해 유한요소해석을 수행하여 기존 모델과 수정된 2층 점소성 모델에 대한 결과를 시험 데이터와 정량적으로 비교분석하여 MPPO 소재의 기계적 거동을 기술하는 모델을 확인하였다. In this study, mechanical properties of the modified polyphenylene oxide (MPPO) were measured using a uniaxial tensile test. Based on this, the modified two-layer viscoplastic model describing the mechanical behavior of MPPO was applied to conduct a parameter study concerning material constants through finite element analysis. Through this, meaningful material constants were determined for the material model, using which, a computational design of experiments using the interior central composite design (ICCD) was established. Then, the root mean square error (RMSE) for load and displacement between test and analysis was calculated. Subsequently, surrogate models for the relationship between material constants (input) and RMSE (output) were generated using a back-propagation neural network (BPN). The optimization problem of material constants was formulated and using the non-dominant sorting genetic algorithm-II (NSGA-II), an optimal solution of material constants was calculated. Based on these results, finite element analysis was performed to validate the model describing the mechanical behavior of the MPPO material by quantitatively comparing the results obtained using the conventional and modified two-layer viscoplastic model with experiment data.
