PACS 유지보수 서비스의 중요성을 살펴보고 PACS 분분별 제안요청 요소를 분석하여 향후 시스템 유지보수 계약의 지표를 제공하는데 목적이 있으며 경희의료원의 PACS 유지보수 제안서요청의 사례를 중심으로 유지보수 RFP 작성의 필요성, 중요사항 및 분야별 요구사항 등에 대하여 기술한다. 제안 부문은 9 개로 구분하였으며 총 139 항목의 제안 요청 사항을 정리하였다. 제안 요소 연구의 결과는 다음과 같다. 1. PACS 유지보수 분야는 PACS Software 부문, 데이터베이스 부문, 서버 및 스토리지 부문, 네트워크 부문, CR 및 DR System 등과 같은 영상획득장치에 관한 부문, 판독용 및 임상용 모니터 부문 등으로 구분하며, 각 부문별 제안 요구사항을 기술한 제안요청서를 작성하여 각 부문별 제안서를 요청하여야 한다. 2. 병원에서는 PACS 부문의 외주관리를 체계적으로 구분 관리하여 시스템 유지보수의 수준을 높이고 이를 질 높은 의료서비스로 연계되도록 하여야 한다. 3. PACS 관련 회사는 병원에서 요청된 제안 요청사항을 수용하며 질 높은 관련부문 서비스를 제공하기위한 기술적 배경을 체계화하여야하며 향후 주요 매출원으로 자리 잡게 될 유지보수 서비스를 상품으로 인식하고 이에 대한 적극적인 상품화전략과 홍보 노력이 필요하다.

요구사항에 대한 우선순위는 요구공학에서 핵심적 활동으로 매우 중요하다. 추출된 요구사항을 소프트웨어 제품 개발의 목표와 조직에 적절하도록 우선순위 방법과 관점 등을 선택할 수 있는 연구가 미흡하고, 요구 분석 단계에서 우선순위 프로세스가 내재화되지 못하고 있다. 요구사항 우선순위는 프로세스 모델, 제품 종류, 우선순위 프로세스에 대한 경험을 바탕으로 주어진 요구사항에 대해 이해관계자들이 우선순위화하기 위한 방법과 관점 등을 선택하는 활동으로 시작된다. 따라서 본 논문에서는 개발 제품의 목표와 조직에 적합하도록 우선순위 방법과 관점 등을 선택할 수 있는 적응적 우선수위 기법을 제안하고, 핸드폰 소프트웨어 개발에 적용하여 그 효과성을 보이도록 한다. 본 논문에서 제안하는 우선순위 기법의 유연성과 다양성을 통하여 요구 분석단계에서 우선순위 프로세스의 정착에 기여할 수 있다.

Personal Health Records(PHR) service offers patients a convenient and easy-to-use solution for managing their personal health records, crucial medical files, and emergency contacts. In spite of the indispensable advantages, PHR service brings critical challenges that cannot be avoided from consumer side if the security of the data is concerned. The problem of user's privacy infringement and leaking user's sensitive medical information is increasing with the fusion of PHR technology and healthcare. In this paper, therefore, we analyze the various security aspects that are vulnerable to the PHR service and needed to be resolved. Moreover, we analyze the security requirements from the point of view of the PHR users and application service providers and provides the PHR security mechanism for addressing PHR security threats and satisfying PHR security requirements.

A well-designed mathematics lesson is the foundation for effective mathematics instruction. Given this significance, this paper focused on analyzing what would be important elements for in-service teachers in planning an elementary mathematics lesson. For this purpose, a total of 27 in-service teachers were asked to write down whatever they would consider important in designing a mathematics lesson. A mathematics lesson plan prepared by a pre-service teacher was provided for the in-service teachers. They were then asked to analyze the strengths of the lesson plan and to provide detailed feedback on how to improve it. The results of this study showed that the in-service teachers tended to analyze the given mathematics lesson plan in terms of what they considered important regarding lesson design. Such elements were specified when the in-service teachers described the strengths and feedback for improvement of the lesson plan. In particular, the aspects of instructional strategies and materials were explained in detail. Based on these results, this paper is expected to provoke discussions on lesson design of in-service teachers and subsequent research.

Evalution of counter drone systems is conducted in order to designate plausible countermeasues against possible drone threats, assess the level of safety of national major facilities and derive complementary measures for detected weakness. Recently drone threats by North Korea have heavily impacted ROK(Republic of Korea) people and it has been stronly stressed to build efficient counter drone system for make the society protected and secured against drone threats. The researchers has conducted field investigations for some of national major facilites. There is, however, no standardized evaluation checklist, so we have proposed an evaluation checklist for counter drone systems though thinking process of RMA(Revolution in Military Affairs). This paper is to introduce the evaluation checklist for properly diagnosing each counter drone system.

산업보건 역학의 연구결과를 우리가 어느정도로 신뢰할 수 있는지, 또는 어느정도의 정보를 제공할 수 있을지를 결정하는 요인들 중에서 중요한 것으로 간주할 수 있는 것은, 측정된 폭로자료(Exposure data)가 어느정도인지(amount), 얼마만큼 구체적이며(specificity) 그리고 얼마만큼 정확한지(precision)에 관한 것이다. 이상적으로는 우리는 각 개인개인의 폭로량을 구하고 이에 관련된 질병발생의 정도를 측정하고자 한다. 이러한 연구야말로 다른 폭로에 대하여도 일반화할 수 있는 양-반응관계를 추정하게 할 것이다. 그러나 실제로는 측정된 폭로자료를 구하기가 어렵거나 또는 아예 이러한 자료가 존재하지 않는 경우가 흔한데 왜냐하면 기술적으로 제약(특정한 물질에 대한 분석이 아직 불가능하거나)이 있거나 부족한 인적 및 물적 자원때문이다. 그러므로, 대부분의 경우에 폭로수준은 이러한 직접적인 폭로 측정자료 대신에 다른 자료로 부터 간접적으로 알아내야 한다. 이 글은 작업장 환경의 특성을 파악하는 것에 대한 개념 및 몇가지 방법 및 토의할 만한 사항을 요약한 것이다. 이들 중에서 가장 중요하게 다루게 될 사항은 아무래도 작업장에서 근로자 폭로이 강도(intensity)와 기간(duration)을 추정하는 것이 될 것이다. 이에 더하여 (예를 들어 병원환자에 대하여 환자-대조군 연구를 행하는 경우와 같이) 지역사회 연구(community studies) 또는 등록자료를 기초로 한 연구(registry-based studies)에 대한 직업적 폭로의 평가에 대하여도 간략하게 언급하도록 하겠다. - 저자 주 -

Processors for a base station controller such as call control processor have to serve usersdemand. Some of processors have been still used for the processing of call and 0&M (operation and maintenance) management by adopting embedded board type. This type can not provide users with a wide variety of environments for testing and debugging. User environments are regarded as a primary system factor in most systems and this is particularly so in designing and implementing the processor for base station controller in mobile communication systems. We describe the design and implementation of new user environment tool named QUEST for the next generation mobile communication system, IMT-2000. The simulation results of performance evaluations demonstrate that our system performs well for a base station controller without performance degradation.

This study looks for the requirements for adaptive courseware and provides background for developing effective adaptive courseware. Most adaptive courseware does not adequately reflect the requirements of learners. If it properly reflected learners' requirements well, it could be used more effectively. therefore, this study analyzes and suggests the requirements of an adaptive courseware for pre-service teachers who are majoring in computer education. The study methods were factor analysis and frequency analysis through survey. The results show that the important elements of an adaptive courseware are a learning style designed according to individual differences as well as an instruction model appropriate to the subject domain. The study examined adaption by learner level, by learning objective, by learning style, by method of learning content, and by learning history in that order. Therefore while the most of adaptive courseware support learning style; we propose that the adaptive courseware will support learning objects and instruction model as well.

As the application area of software grows bigger and the importance of software quality increases, software quality evaluation method is also getting a lot of attention. To evaluate the software quality properly, we need an objective and concrete evaluation mechanism. In general, practitioners customize the international standards to their own needs for this purpose. Package software documents plat an important role in software quality evaluation because it provides the information that helps customers use the software effectively and conveniently. h great deal of efforts has been made in terms of international standards for documentation and documentation process. However, those international standards are too abstract to be applied directly to domestic software packages. In this paper, we developed a guidelines and checklists for writing and evaluating package software documents. Our research basically followed ISO 12119, ISO 9127 and some related research results. Also we proved the effectiveness of this research through actual tests with package softwares.

It is difficult to provide proper cloud services for cloud users, because the number of cloud services are increasing and the type of cloud services are diversifying. To overcome this problem, the concept of cloud service broker is presented to mediate cloud services between cloud providers and tenant. The most important role of cloud service broker is to finding cloud services that fulfill requirements of tenant. However, current existing cloud service broker conduct passive requirements analysis process with cloud service expert's assistance. In addition, the systematic functional and non-functional requirement analysis is insufficient. Therefore, we need the new methods for requirement analysis to find nearest service that matches with requirement of tenant. In this paper, we apply pairwise comparison from AHP method to analyze requirement automatically and systematically. It calculates score of service by comparing requirement with service specification, calculating importance rate, and so on.
