이 연구는 정보 간의 관계에서 도출되는 특징을 적합하게 보여줄 수 있는 시각화를 위한 선행연구이다. 정보의 관계에 주목하는 이유는 관계 구조를 통해 정보의 성격과 특징을 파악할 수 있기 때문이다. 정보의 관계는 사회연결망 분석을 통해서 파악할 수 있다. 정보를 구성하는 개체와 개체 사이의 관계는 다양한 요소를 지니고 있으며, 연결망의 관계 분석 지표를 통해 관계의 성격과 특징을 도출해 낼 수 있다. 이 연구에서는 사회연결망에서 관계의 성격을 도출하는데 중요한 지표로 다뤄지는 영향력을 연구범위로 설정하고, 연결망 내의 관계의 요인과 영향력의 지표를 분류하고 연결한다. 이를 통해 사회연결망에서 영향력을 나타내는 관계의 요소를 중심으로 관계의 시각화 과정에 있어 적합한 시각화 프로세스를 온톨로지 개념을 사용하는 시멘틱 그래프에 적용해 보았다. 영향력의 각 관계 요소는 공통적인 개념과 성격, 측정 요소를 통하여 노드와 링크의 네트워크 형태의 그래프로 형성되었다. 영향력 시멘틱 그래프는 사회연결망의 영향력 요소를 이해하고, 분석하는데 유용하게 사용될 수 있음을 확인할 수 있다. 또한 시멘틱 그래프의 적용 범위를 연결망 시각화 전반을 확장하여, 합리적이고 효율적인 시각화 프로세스의 설정이 가능함을 알 수 있다.

This study is a nationwide survey of Korean public libraries to identify and analyze the usefulness of 69 evaluation indicators of a public library proposed by the authors in the previous paper. A random sample of respondents including library managers, librarians, and users rated the usefulness of each indicator in assessing the performance of a public library. The results of this study could be used as the basic data in the evaluation of public libraries by selecting appropriate indicators and giving weight on each indicator according to the specific evaluation purpose.

본 연구는 삶의 질에 관한 관점을 우리 나라 도시저소득층의 주거실태를 중심으로 살펴보고자 한다. 이를 바탕으로 주거빈곤층의 삶의 질 향상을 위한 발전대안을 모색하도록 한다. 국내외 거의 모든 ‘삶의 질’선행연구에 있어 중요한 지표로서‘주택’,‘주거환경’,‘주거장소’등 주거에 관한 상이 포함되어 있다. 즉 삶의 질 연구에 있어 주택 및 주거환경은 가장 기본적이고 필수적 요소임을 확인할 수 있다. 주거빈곤을 기능적 측면, 경제적 측면, 최저주거기준 측면, 그리고 주거권 측면에서 분석하고, 한국의 주거빈곤실태를 파악하였다. 특히 서울을 비롯한 대도시의 주거빈곤층은 달동네.산동네라 불리는 불량주거지, 비닐하우스, 쪽방 등에 거주하며, 이들은 주로 주택점유 형태상 전세, 보증부월세, 월세 등의 임차가구의 대부분을 차지한다. 삶의 질과 주거환경개선을 위한 발전대안 모색을 위해 주거분야 ‘삶의 질 지표’를 제안하였다. 지표의 내용으로 주택 그 자체뿐 아니라 주거기능이 원활하도록 하는 공공서비스, 안전 등의 광의적 접근이 필요함을 강조하였다. 아울러 삶의 질에 관련된 정책과제를 해결하기 위해서는 적어도 네 가지 부문(정부, 민간부문, NGO/CBO, 주민)별 각자의 역할을 강조하였다.

본 논문에서는 대규모 평시 또는 감염병 발생이전 지자체별 취약성 평가를 통해 감염병 발생 및 확산에 영향을 미치는 취약지표를 평가해보는 것이다. 이를 위해 국내 코로나19 대처사항(각종 회의자료 및 보고자료 등), 선행연구 등을 기반으로 확산취약시설, 감염취약계층, 사회적 취약여건, 대응능력(보건·의료/재정적, 사회적 대응역량) 총 4개의 증감유형으로 분류한 후 세부 평가지표로 약 24개로 세부지표를 선정하였다. 이러한 취약성 평가 결과는 지자체별 특성에 맞는 감염병 대응정책 수립에 필요한 근거자료를 마련하는 기초자료로 활용 가능할 것이다.

In order to clarify the relation between the physical properties and the strength parameters of compaction materials and to develop a method for evaluating the strength parameters required for design from the physical indices including void ratio and dry density, compaction test, one-dimensional compression test, and exhausted-drained triaxial compression test were carried out with decomposed granite soils. The test results showed that the specimens became over-consolidated by compaction and the increase of the strength parameters of the specimens by the increase of the compaction energy could be verified quantitatively. A method for the evaluation of strength parameters from the void ratio of soil after compaction using preconsolidation theory which evaluates over-consolidation of materials was developed and its engineering applicability was tested for verification.

This paper presents our study on speech recognition performance prediction. Our initial study shows that a combination of speech quality measures effectively improves correlation with Word Error Rate (WER) compared to each speech measure alone. In this paper we demonstrate a new combination of various types of speech quality measures shows more significantly improves correlation with WER compared to the speech measure combination of our initial study. In our study, SNR, PESQ, acoustic model score, and MFCC distance are used as the speech quality measures. This paper also presents our speech database verification system for speech recognition employing the speech measures. We develop a WER prediction system using Gaussian mixture model and the speech quality measures as a feature vector. The experimental results show the proposed system is highly effective at predicting WER in a low SNR condition of speech babble and car noise environments.

This study develops a set of measures for public library services to children. It is designed to use both measures for library service quality including personnel, library materials and resources. spaces for the service, and other services. and those for library customer satisfaction on equal basis. It specifies 23 scales for 4 each dimensions of measures for service quality, based on the suggestions both from the consulting members of specialists and from the personnel of the National Library for Children and Young Adults. and from the results obtained from the analysis on the questionnaires from the public librarians to children and researchers in this fields. This measures were testified by applying to 18 sample libraries.

The purpose of this study was to identify the service factors of university libraries which aim to improve the educational welfare of the disabled, and to develop an evaluation indicator to evaluate these vital service factors. To proceed with this study, guidelines of public library services for people with disabilities, and previous research and job description of academy library analysed and developed indicators suited for evaluating academic library services for people with disabilities. A pilot survey and main survey about the evaluation factors and indicators conducted with librarians who work for university libraries, and the questions were refined by exploratory factor analysis of the data collected from the survey. As a result, through the process of identifying reliability and validity, it turned out that the evaluation factor and subordinate index of university library services for the disabled consisted of 8 factors and 33 indicators.

This study describes a set of user experience indicators developed for the evaluation of knowledge and information resource systems. The user experience perspectives had emerged as a new analysis standard in the field of information media and information service research. The study included a survey conducted to verify the derived experience factors and developed them as indicators. The survey data was gathered from 158 participants in the preliminary and 480 participants in the main study. The applied analysis techniques were descriptive statistics, the exploratory factor analysis, the confirmatory factor analysis, the correlation analysis, and the path analysis. The results introduced seven user experience factors, 37 detailed user experience factors, and 105 system perception factors as the final user experience indicators. The developed and verified indicators should measure the degree of user experience perceived by users of the knowledge and information resource system and conduct effective evaluations that reflect correlation rather than a simple comparison of each experience factor.

The purpose of this study is to analyze the types of present situation data related to school facilities through existing literature and related systems and to develop indicators related to improvement of educational environment that can have an important influence on students' education and life in general. In this study, we conducted a second Delphy Survey to establish the educational environment improvement index. As a result, a total of 88 education environment improvement indicators were set, including 43 indicators on the quantitative aspects of the area, adequacy of general classrooms, and appropriateness of multi-purpose steel sugar, 34 indicators on the qualitative aspects such as the level of seismic performance, age of fire facilities, aging of toilets, and aging of finishing materials, and 11 indicators on operational aspects such as energy usage and user satisfaction.
