국가 보건의료체계(health care system)가 올바르게 기능하기 위해서는 의료체계를 구성하는 각 요소들간의 유기적인 상호 작용이 대단히 중요하다. 정보체계는 이러한 유기적인 상호 작용을 위해 보건의료체계의 각 영역에서 꼭 필요한 시스템이다. 보건의료 서비스를 효율적으로 생산하기 위해서 투입하는 자원의 개발과 배치 체계는 물론 생산된 보건의료 서비스를 소비자가 효과적으로 이용할 수 있도록 하는 서비스 전달체계(delivery system)의 전과정에서 보건의료정보체계는 중요한 인프라가 되고 있다. 정보체계는 궁극적으로 보건의료체계가 지향하는 목적을 달성할 수 있도록 짜여져야 한다. 다시 말해, 의료체계의 각 하부영역에서 의료이용의 접근성(accessibility), 형평성(equity), 서비스의 의과학적 질(scientific technical quality), 포괄성(comprehensiveness) 등 보건의료체계가 추구하는 가치를 정보체계에서도 그대로 담아 낼 수 있어야 한다. 또한 정보체계를 구축하기 위한 요건으로 각 사업 영역별 표준화, 사업 영역간의 상호관계, 공공과 민간의 역할 분담, 정보 관련 시선과 인력, 정보기술 등의 인프라, 각 사업 영역별 정보화에서 담아야 할 정보 내용(contents, DB) 등에 대한 사전 기획이 수립되어야 한다. 그 동안 보건의료분야의 정보화사업은 1996년부터 보건소기관의 행정, 진료, 보건 업무지원을 위한 보건소정보화사업과, 1995년부터 초고속공공응용서비스 사업의 일환으로 추진해 온 전염병, 혈액유통, 장기이식, 외래진료예약, 원격진료, 응급의료, 원격치매진료 시스템 구축사업 등이 있으며, 응급의료, 혈액관리, 장기이식, 전염병정보, 외래진료예약시스템을 통합한 보건의료정보통합서비스시스템(1998년) 구축사업 등이 있었다. 이러한 사업들에 대해 현재 평가되고 있는 문제점들로는 정보화 사업에 대한 전략과 비젼이 부재한 상태에서 지나치게 정보기술 중심으로 추진되다 보니 보건의료 정보의 공유나 활용이 전혀 이루어지지 않거나 매우 제한적이었고, 시범사업의 경우는 초기 사업을 추진하기 위한 주체가 명확하지 않았고, 관련 인력의 훈련과 양성이 안 되었으며, 사업 확대를 위한 법적 기반의 취약, 정보화 사업이 부실한 데 대한 평가 기준과 대안 제시 등이 매우 취약한 것이 문제점으로 나타났다. 특히, 정보 내용과 DB 구축을 위한 표준화 등에 대한 사전 설계 부재는 개발된 정보시스템의 운영을 결정적으로 어렵게 만든 요인이 되고 있다. 전반적으로 기존의 정보화사업은 사업 추진을 위해서 꼭 필요한 비젼 수립, 비젼에 따른 목표 설정, 전략 개발, 관리체계 구축, 운영방안 수립 등 단계적인 정보화 계획이 부재한 것으로 평가되고 있어 보건의료정보체계 구축을 위한 종합 비젼 기획(ISP)이 시급한 실정이다.

Data grid shares distributed large data via wide-band network. Such grid environment consumes much time for large data transmission. Because it is implemented on internet as physical network. Many replication strategies were proposed for solving this problem, but they are not optimal in real Data grid environments. Because they were proposed that based on logical topology without consideration of real internet architecture. Grid data access time is largely influenced by internet architecture as physical network of Data grid. In this paper, we propose a new data replication strategy RSIA(Replication Strategy based on Internet Architecture) based on internet architecture. The RSIA places replicas considering structural hierarchy in each element of internet, and avoid the performance bottlenecks to reduce system performance degradation when a data transfer. Through simulation, we show that the proposed RSIA data replication strategy improves the performance of Data Grid environment compared with previous strategies.

The purpose of this study is to develop a measurement tool for self-image of the teacher librarian by semantic differential meaning scale and to analyse the correlation between their self-image and individual characteristics. This study suggests that the teacher librarians have regarded themselves as friendly, planned, sensitive and cooperative persons as well as persons with discernment. On the other hand, there are some negative self-images such as partial, poor and uninfluential persons plus disregarder and a reserved persons. The educational career of teacher librarians' background has influence on evaluation area of the self-image. This result shows that senior teacher librarians' role performance as a adviser or a leader is very important. So mediator role of KLA and KSLA has to be reinforced to beat the exchange and collaboration between the senior and the junior teacher librarians. It is necessary to appoint the teacher librarians obligatorily in oder to feel their professional security and sense of achievement, also to appreciate expertise of them through role clarification among the human resources of the school library.

A 3D-ray tracing tool is a software considering reflection, penetration, and diffraction of the signals to provide accuracy. To provide communication resources effectively, communication standards adopt Heterogeneous Networks (HetNets) that includes small cells. A 3D performance evaluation methodology becomes more and more important since the coverage of the small cell networks is narrower than that of the macro cell networks. It is difficult to directly apply conventional 2D mathematical models due to the complexity of small cell network; since they have many considerations such as topography, placement of buildings and 3D beamforming techniques. In this paper, we introduce an effective performance evaluation methodology for small cell networks using 3D-ray tracing tool. From simulation results, we conclude that new performance evaluation methodologies by using 3D-ray tracing tool is more suitable than conventional methodology for small cell networks.

This paper proposes to segment skin color areas using a clustering algorithm. Most of previously proposed clustering algorithms have some difficulties, since they generally detect hyperspherical clusters, run in a batch mode, and predefine a number of clusters. In this paper, we use a well-known elliptical clustering algorithm, an EM algorithm, and modify it to learn on-line and find automatically the number of clusters, called to an EAM algorithm. The effectiveness of the EAM algorithm is demonstrated on a task of skin color region segmentation. Experimental results present the EAM algorithm automatically finds a right number of clusters in a given image without any information on the number. Comparing with the EM algorithm, we achieved better segmentation results with the EAM algorithm. Successful results were achieved to detect and segment skin color regions using a conditional probability on a region. Also, we applied to classify images with persons and got good classification results.

There has been significant movements in the provision of equal access to library and information services for persons with disability. This study aimed to analyze the use and needs of library services of disabled people with a survey. The survey data revealed that the majority of disabled persons did not visit library and not experience library sol-vices. The main reason was reported that they had poor information about the library services. Also, they did not satisfy the variety, sufficiency, accessibility, up-to-dateness of the materials in general. And there were difference of favorite programs and needs among different kinds of the disabled. Therefore, active guidance and public relations about library services. improvement of accessibility for the disabled by building digital collection, resource sharing and extension of services by building library cooperation network, and the arrangement of librarians for the disabled and education for them should be back up for improving library services for the disabled.

The number of collaboration professors has significantly increased since the last decade, along with rapid technological developments and the necessity of entrepreneurial universities. Despite the expansion of collaboration professor recruitment, few empirical studies have examined the contribution of collaboration professors to university-industry collaboration. In particular, we do not have sufficient knowledge about the role of collaboration professors in the start-ups of undergraduate students, which is one of major duties of these professors. Following previous studies, this study constructs panel data of 203 universities explaining the proportions of collaboration professors, activities of undergraduate students, support of universities for students preparing new firms, and attributes of universities from 2017 to 2019. The results indicate that the percentage of collaboration professors is not statistically related with the start-ups of undergraduate students, whereas that of full-time professors working at organizations specializing in start-ups is positively and significantly associated with the number of new firms of undergraduate students. In addition, the percentage of students who had attended the start-up camps and the availability of financial support from universities for students who attempt to create new firms positively influence the start-ups of undergraduate students.

As Information Technology developed, Information requirement has been went higher. In the field of GIS(Geographic Information System) more information is processed more quickly and accurately. Especially, quick analysis of forest fire information (topography, ignition point, weather condition, etc.) over a wide area is essential in order to minimize victim, environmental damage, and economical damage, decide course of evacuating, estimate a fire spread course, and attack resource arrangement. We determined a fire spread distance at each unit time through an experiment with various slope degrees and distinction of flat, upslope and downslope. For the tests on the upslope, as the slope increased, the rate of spread increased. On the downslope in contrast with the upslope, as the slope increased, the rate of spread decreased. We analyzed a spread rate of forest fire on each slope as the method classified upslope(+) and downslope(-) using the results obtained from the experiment. Consequently, the proposed method is able to be used to effectively support the attack of forest fire by providing accurate predictions of fire spread.

최근 우리나라 어선어업은 한중일 어업협정, 연안 어업자원 감소 및 연안오염 등 사회적, 환경적 변화가 급변하고 있어 이들을 고려한 어선 선형개발이 필요로 한다. 현재 우리나라의 어선 중 연안지역에서 조업하는 5톤 미만의 소형어선은 전체 어선 중 $65\%$ 이상으로 구성되어 있으나 선박의 크기가 작고 부가가치가 낮은 관계로 지금까지 전문적인 연구는 거의 없었던 것이 현실이다. 한편, 서$\cdot$남해 연안에서 작업 및 항해하는 연안어선들의 해양사고 발생율은 전체사고의 $69.6\%$로 매년 증가하고 있는 추세이다. 전체 어선 안전사고 중 부유폐어망, 로프 등이 추진기에 감긴 사고는 전체 사고의 $10.4\%$로 매년 증가하고 있다. 이에, 추진기 손상에 의한 어선 사고와 연관하여 추진기를 보호하기 위한 장치로서 물분사 추진기(Water-Jet), 펌프제트(Pump-Jet)장치들이 있으나 이들은 고가 수입품으로서 영세한 어민들의 소형어선에 장착하기에는 한계가 있어, 본 연구에서는 폐그물, 로프 등 해상 부유물에 의한 추진기 손상이 발생되지 않는 프로펠러 보호터널 부착 추진장치를 개발을 목적으로 한다. 프로펠러 부착 추진장치는 기존 선미를 수정하여 추진기를 선체 안쪽으로 배치하며 돌출되는 부분은 덕트로 보호하고 있으며 이러한 추진기는 워터제트 추진기와는 달리 가격이 싸고 그물이나 부유물에 걸리지 않고 고장 시 신속한 대응이 쉬워 소형 연안어선에 적합할 뿐만 아니라 그물, 부유물, 갯벌이 많은 국내의 서$\cdot$남해 연안에서 작업 및 항해 시 매우 유용할 것으로 판단된다. 본 연구는 `프로펠러 보호터널 부착 연안어선의 선형개발`을 최종목표로 수행하였으며, 연구개발 내용은 기존 소형 연안어선의 분류 및 특성 조사 연구, 프로펠러 보호터널형 선미 선형 개발, 기존 선형 및 보호터널형 선형의 모형시험, 개발선의 구조강도 특성, 프로펠러 설계 및 단독시험, 보호터널 부착 추진기의 효율 검증 및 개발 대상 어선의 조선공학적 제 계산, 설계도작성 등을 실시하였다. 주요 요소 기술로서는 프로펠러 보호터널 부착 선형의 모형시험을 통하여 선미선형을 개발하며 FRP판부재의 구조강도 특성을 분석하고 그 결과를 활용하여 4톤급 연안어선의 시제선을 건조하고 시운전을 통하여 주요성능을 확인하였다.
