본 논문에서는 실시간 분산 시스템의 객체지향 소프트웨어 시험을 위한 확장된 정형 시험 모델을 제안한다. 제안된 모델은 객체 관계 다이어그램, 객체 상태 다이어그램 및 객체내의 블럭흐름 다이어그램을 기반으로 하고 있으며, 동기화, 통신 형태, 시간의 제약성 등 실시간 분산 시스템의 주요 개념들을 반영하여 확장되고 있다. 제안된 정형 모델로부터 객체지향 소프트웨어 시험을 위한 방법과 도구들을 제시하고 일부 도구의 프로토타입을 구현하여 봄으로써 모델의 적용 가능성을 확인한 결과를 기술한다. In this paper, we propose an extended formal model for testing object -oriented real-time distributed systems. This model is based on Object Relation Diagram, Object State Diagram, and Block Branch Diagram, and extended to add the concept of real-time distributed system, such as, synchronization, communication type, and timing constraints. We suggest methods and utility tools for object-oriented software testing from the proposed formal model, and describe the validation result to show the applicability of the model by prototyping some of them.

정보서비스 관점에서 대규모 정보 서비스 시스템을 개발하기 가장 좋은 방법중의 하나가 웹의 서비스 능력과 데이터베이스 관리시스템의 유용한 기능을 상호 보완적 측면에서 통합하는 것이다. 웹과 데이터베이스 관리시스템 통합의 핵심 요소가 웹-DBMS 통로이다. 웹-DBMS 통로는 데이터베이스 관리시스템에 대한 요청을 웹의 기술을 이용하여 데이터베이스 관리시스템에 접근하고, 데이터베이스 관리시스템의 처리 결과를 웹서버에게 전한다. 바다/웹은 웹의 서비스 능력과 객체지향 데이터베이스 관리시스템인 바다-III를 서로 보완적 측면에서 통합한 웹-DBMS 통로이다. 이 논문에서는 웹과 바다-III를 통합하기 위한 설계와 구현상의 경험을 설명하고, 데이터베이스에 대한 질의들을 통해 바다/웹의 효과를 분석했다. We believe in terins of information service systems that one of the best ways to develop a large scale database service system is to integrate the service capability of the Web and the dta management facility of database management systems in a complementary fashion. In such integation a database gateway in the core component, the web-database gateway accesses database management systems to serve the requests represented by using the Web technology. We designd BADA/Web be independent from the Web and DBMS and much as possible, which minrrizes the performance overhead caused by connecting database management systems and makes BADA/Web portable. BADA/Web incorporates TCL into a ibrary of it and handles concurrent requests efficiently. In this paper we describe our desingn and implementation experience in integrating the Web and BADA-III We evaluate the performance of BADA/Web by measuring and companing the latency and average response time for a simple query and also explore the effects of BADA/Web with some synthetie queries .

N/A Hypothyroidism and hyperthyroidism are both associated with a variety of muscle abnormalities, from myalgia to myopathy. There are several reports of autoimmune thyroiditis associated with various rheumatic disorders, such as systemic sclerosis. Polymyositis, however, has been reported in very few cases, if any, especially after the treatment for active hyperthyroidism. A 22-year-old woman developed idiopathic polymyositis during the treatment of Graves' disease with propylthiouracil. She developed severe proximal muscle weakness during the treatment for hyperthyroidism. Her serum creatine kinase level was elevated. Electromyography, muscle biopsy and the clinical course of the patient's illness were consistent with idiopathic polymyositis. Whether this coexistence of Graves' disease and polymyositis represents a cause-effect association or a chance occurrence is unknown.

소프트웨어 재사용은 기존의 소프트웨어 부품들을 재사용함으로써 소프트웨어 개발의 품질과 생산성을 향상시킨다. 이 논문에서는 먼저 소프트웨어 재사용에 관련된 몇 가지 문제들을 설명하고, 잘 알려진 두 가지 소프트웨어 분류 체계를 비교하여 기술하였다. 마지막으로 소프트웨어 개발자들이 기존의 소프트웨어 부품들을 등록, 검색, 수정, 삭제하는 작업을 도와주는 다수 사용자용 라이브러리 관리 시스템의 설계 및 구현을 기술하였다. 이 시스템은 사용자에게 편리한 메뉴 방식 인터페이스, 라이브러리에 저장되어 있는 부품들에 대한 보안 기능, 소프트웨어 재사용에 관한 다양한 통계 정보 등을 제공한다. 이 시스템은 UNIX 위에서 Troll/USE DBMS를 사용하여 C 언어로 구현되었다. By using existing software components, software reusability improves the quality and productivity of software development. In this paper, we first discuss the several issues related to the software reuse. Then, we compare and address two well-known software classification schemes. Finally, we describe the design and implementation of a multi-user LIbrary Management System(LIMS) for software reuse. The LIMS supports insertion, retrieval, update, deletion of reusable software components. It provides a convenient menu-driven interface and protection mechanism. Also, the LIMS provides various statistical information about the paradigm of software reuse. The system has been implemented in C under UNIX and with Troll/USE as the underlying database management system.

N/A Background : The zonal differentiation of hepatic necrosis is important in the aspect of treatment, follow-up and prognosis of patients. The purpose of this study was evaluating the clinical usefulness of serum isocitrate dehydrogenase (ICDH) as a marker of centrilobular hepatic necrosis in patients with hyperthyroidism. Methods : We determined the serum ICDH and alanine aminotransferase (ALT) activities in 56 patients with hyperthyroidism, 16 patients with chronic viral hepatitis, and 17 normal controls. Results : The activities of serum ICDH were significantly higher in patients with hyperthyroidism than those of patients with chronic viral hepatitis or normal control (p<0.01), even though those of serum ALT were higher in patients with chronic viral hepatitis (p<0.01). The ratio of serum ICDH and ALT activities were markedly different between the patients with hyperthyroidism and chronic viral hepatitis (p<0.001). There was a significant correlation between the serum ICDH and ALT activities in patients with hyperthyroidism as well as in those with chronic viral hepatitis (p<0.05). In patients with hyperthyroidism, the serum ICDH levels were more significantly correlated with serum triiodothyronine (T3) than thyroxine (T4) levels. In a patients with hyperthyroidism and elevated ALT levels, the serum ICDH activity decreased progressively and was normalized ultimately, as serum ALT level and thyroid function were normalized with antithyroid medication. Conclusion : The serum ICDH or ratio of serum ICDH and ALT activities might be useful clinically in differentiating the centrilobular from periportal hepatic necrosis, and following up the degree of hepatic necrosis in patients with hyperthyroidism.(Korean J Med 58:189-196, 2000)
