Due to technological advances and the establishment of evidence-based medicine, radiological examinations are playing a crucial role in modern medicine, as a result of which they have been steadily increasing, and the rate of increase has intensified in the 2000s. Although this is a global phenomenon, the increase of radiological examinations in Korea is also high due to the introduction of the National Health Insurance Coverage Expansion Policy, so-called Moon Jae-in Care, for ultrasonography and magnetic resonance imaging. For accurate and rapid diagnosis of diseases, it is necessary for doctors to order appropriate radiological studies. However, the increase in radiological examination has created many problems, such as increased medical costs, decreased diagnostic accuracy due to radiologist burnout, and increased patient exposure to radiation. To reduce unnecessary imaging studies, a number of measures could be deployed including the development of clinical guidelines to select appropriate radiological examinations for each clinical situation.

The specification written in CSP-based specification language is analyzed and the state transition table that represents the behavior of a specified protocol is prepared. Then refe-rencing this state transition table, user can verify the behavior of a protocol through a user interface, and important features such as deadlock, unreachable state and unspecified input- output are verified. Using the system, detection and correction of a mis-specified protocol are possible at the initial phase of a development cycle.

The technique of Software Reusability have been introduced in order to enhance the development productivity and the quality of the software itself. The currently developed and used Software Reusability with the poor interconnection of the existing Software Development Methodology during the life cycle of the Software Development. In this paper, We will analyze and design a project deliverables database system which can share and reuse project deliverables.

To overcome today's software crisis, we should reconsider software reusability in software development. Recently software reusability become a key issue in software engineering. Reusing software com-ponents enhance the productivity and quality of software. In this paper, the identification and classification system devel-oped for the reuse system. While a great deal of research over the past several years has been devoted to the component libraries and reusable software component, the composition issue of how to extract reusable components from existing systems, to classify reusable component has remained relatively unexplored. The identi-fication and classification system for the reusable components will support practical application for the reuse system.

Purpose: We evaluated the effectiveness of second-line maximum androgen blockade (MAB) with an alternative antiandrogen in patients who relapsed after initial MAB. Materials and Methods: We retrospectively analyzed 47 patients with prostate cancer who relapsed after initial MAB, including surgical or medical castration combined with antiandrogens, from January 1998 to December 2009. When the serum prostate-specific antigen (PSA) level was increased on three consecutive occasions, we discontinued the antiandrogen and then administered an alternative antiandrogen. Seven patients were assessed for antiandrogen withdrawal syndrome (AWS). The effect of the second-line MAB was evaluated by the serum PSA level, and response was subdivided into ≥50% and <50% PSA reductions from the baseline PSA at the start of second-line MAB. Results: PSA reduction was observed in 32 patients (68.1%). Among them, 23 (48.9%) achieved ≥50% PSA reductions with a mean response duration of 13.4±5.4 months. Nine (19.2%) patients reached <50% PSA reductions with a mean response duration of 12.2±6.2 months. The time to nadir PSA level after first-line MAB in the ≥50% PSA reduction group, <50% PSA reduction group, and PSA elevation group was 15.6±12.9 months, 11.8±6.0 months, and 8±6.5 months, respectively. That is to say, it was significantly longer in the responder groups (p=0.038). Conclusions: Second-line MAB using an alternative antiandrogen is an effective treatment option before cytotoxic chemotherapy in patients who relapse after initial MAB.

Medical imaging is the one of the most important diagnostic tools of modern medical science and quality control of the medical imaging is already systemized in the advanced countries. However, in Korea, quality control of medical imaging has not been properly performed until now and low quality examinations have been done without any regulation. The Korean Radiological Society, as society of supervision of medical imaging, has emphasized the importance of quality control and in 2003, the law for the quality control of medical imaging was made. In conformity of the law, the regulation of the quality control of medical imaging will commence, but this is just the beginning and there are still many tasks left for settling down and expanding the range of the quality control of the medical imaging. We reviewed the history of the quality control of medical imaging in Korea and explained the particulars of mammography, fluoroscopy, computed tomography and magnetic resonance imaging. We also looked into future prospect and tasks of the quality control of medical imaging. 현대 의학에서 가장 중요한 진단 도구인 영상의학검사는 정도관리가 체계화된 선진국과는 달리, 우리나라에서는 최근까지 적절한 화질 관리 체계 없이 운용되어, 일부 부적절한 품질의 영상의학검사가 남용되는 부작용이 있었다. 대한영상의학회는 영상의학검사의 주관 학회로서 꾸준히 영상의학검사에 대한 체계적 정도관리의 필요성을 주장하였고, 재정건전화특별법에 근 거한 특수의료장비의설치및운영에관한규칙이 2003년 발효되면서 영상의학검사의 정도관리는 법적 제도 내로 들어오게 되었다. 현재 영상의학검사의 정도관리가 제도적으로 실행되고 있지 만 아직 시작 단계에 불과하고, 발전적으로 정착되기 위해서는 여러 과제들을 해결해야 할 시 점이다. 본 종설에서는 우리나라에서의 정도관리 사업의 진행 과정과 유방촬영용장치, 투시촬 영용장치, 전산화단층촬영장치, 자기공명영상촬영장치 검사의 정도관리 실제 그리고 추후 정도 관리 사업의 전망 및 과제를 알아보고자 한다.
