현재 인터넷 공격이 날로 증가하고 있는 추세이다. 더불어 그에 관련된 제품들도 많이 나오고 있는 상황이다. 그러나 정작 이런 제품들에 질적인 면에서 품질을 고려하는 노력이 미흡한 사실이다. 본 연구에서는 침입차단시스템(FW) 제품의 현황을 분석하고 효율성 품질평가 방법을 개발하고자 한다. 이를 위해 침입차단시스템 제품 유형을 대상으로 특성과 핵심 기술 요소를 분석하고 현황 조사 및 분석을 바탕으로 침입차단시스템 제품의 품질평가 기준과 평가방법론을 개발하였다.

서비스 경제의 확산과 경쟁심화라는 현 시점에서 서비스품질은 조직의 장기적인 핵심 가치로 판단되는 것이 타당하며, 조직은 서비스품질을 확보하여 재무성과를 향상시켜야 할 것이다. 조직의 성과는 유/무형의 재무적 요소로 표현되나 이러한 재무성과의 성공과 실패는 리더십, 전략, 고객만족, 정보와 지식, 인적자원, 프로세스 등의 유기적인 체계에 의해 좌우된다. 본 연구에서는 한국표준협회 한국서비스대상의 평가지표를 기본 구조로 하여 평가 지표가 실행과제의 내용을 구성할 수 있도록 지표를 세분화 하고 서비스품질의 개선을 통해 경영성과의 증진을 도모하는 일련의 방법론과 프로그램을 개발한다. 연구의 결과는 기업이 전사적 측면에서 서비스품질 활동을 위한 지표개발로부터 실행계획수립까지의 과정에서 필요한 가이드라인 혹은 실질적인 평가 자료로 활용되기를 기대한다.

인공지능의 발전으로 의료영상 분야에서 딥러닝 기반 질병 진단 연구가 활발하다. 그러나 모델 개발 시 학습 데이터의 개수와 품질은 매우 중요한데, 의료 분야 특성상 접근 가능한 데이터셋이 적으며 오픈 데이터셋은 서로 다른 기관에서 배포되거나 웹상에서 수집된 것으로 진단에 적합한 품질을 기대하기 어렵다. 또한, 기존 연구는 데이터셋이 학습에 적합한지에 대한 품질검증 없이 사용한다. 따라서 본 논문에서는 임상에서 사용하는 화질 평가 요소에 근거를 두고 영역별 화소값 분석을 통한 흉부 X선 영상 품질 평가 기법을 제안한다. 오픈 데이터셋 JSRT, Chest14와 국내 A 병원 데이터셋 AUH에 제안한 기법을 적용한 결과 민감도 91.5%, 특이도 96.1%의 우수한 성능을 확인하였다.

본 연구는 인터넷 쇼핑몰 기업들의 새로운 경쟁요인으로 부각하고 있는 물류서비스 부분의 품질 평가기준이나 평가척도 등에 관한 기존 연구를 현 시점에 맞게 재해석하고 또 새로운 평가 요소를 발굴하여 이를 인터넷 쇼핑몰에 적용함으로써 이용자들의 만족도, 재이용의도 및 타인추천의도의 향상을 꾀하였다. 특히 물류서비스 요인들의 고객만족에 대한 직접적인 영향을 분석함과 동시에 구매 후 행동인 재이용의도와 타인추천의도에 대한 간접적인 분석을 통해 그 영향 정도를 실증적으로 파악하여 쇼핑몰 운영자에게 있어 실질적인 도움을 주고자 하였다.

As Web services cover more and more IT area and the number of their implementation cases increase rapidly, most associates have begun to consider the quality of Web services. They require the framework that helps to evaluate and measure the quality of Web services. OASIS WSQM(Web Services Quality Model) technical committee already published Web Services Quality Model specification version 2.0 in 2006. However, it has been described in conceptually. That is, it contains the model view, classification of quality factors, some activities and associates. So, we need Web services quality description language (WSQDL) shaped in XML. To describe WSQDL schema, we need a new paradigm to represent the Web services quality factors consistently and interoperably. For this we provide the new concept of quality chain in this paper.

Design quality in constructed project is a primary consideration to achieve overall project objectives. It is not easy to evaluate the design quality because various factors are involved in the design process. This paper presents a new approach to improve the evaluation process of design quality In the construction project The evaluation model is developed to satisfy the requirement for implementing the ISO 9000 Quality Assurance Standards in the design process. It is assumed that design changes are resulted from the poor management of design quality. The model relates design changes to design quality management items. It assigns weight ratio to each design quality item to evaluate quantitatively Design Quality Index (DQI) is calculated to assess design quality based on the Objectives Matrix. A case study is performed to illustrate the practical implementation of the design quality evaluation.

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.

In this paper, researching for the video quality estimation of IPTV in the situation that increase the broadcasting network traffic on the IPTV multicasting service using the ETSI TR 101 290 that is the European digital video quality standard estimating method and present the experiment result. Proving that the intimate relation is between IPTV video quality and ETSI TR 101 290 estimation, also ETSI TR 101 290 can detect the video quality factors which can't be detected by the exist video estimation methods.

In this study the need for new service qualify assessment scale is investigated to cope with the paradigm change in library information service and the dimension and model for e-service quality assessment applicable to a digital library are developed. In order to verify newly proposed dimension and model for e-service qualify assessment, the dimension which is developed by employing data collected from NDSL(National Digital Science Library) and its factor are analyzed and casuality analysis between independent and dependent variables is executed based on the proposed e-service qualify model We also analyze the gap between customer's ideal expectation and perception and, finally investigate what is the most important dimension among e-service quality in the digital library from the customer's point of view.

The purpose of this study was to design an extensive evaluation model for the quality of web-based database and to make a comparative analysis of People's awareness of the importance of assessment indices. The evaluation standard developed in this study was constituted by 19 indices and 45 elements in three different areas, including data, service and effectiveness. And a survey was conducted on database experts and nonprofessional users to find out their awareness of the importance of web-based database evaluation elements, and the findings of the study might contribute to laying the foundation for expediting more in-depth research efforts in the future.
