This paper proposes an agent-based adaptive tutoring system that monitors learning process of learners' and provides learning materials dynamically according to the analyzed learning character. Furthermore, it uses fuzzy concept to evaluate learners' ability and to provide learning materials appropriate to the level of learners'. For this, we design a courseware knowledge structure systematically and then construct a fuzzy level set on the basis of it considering importance of learning targets, difficulty of learning materials and relation degree between learning targets and learning materials. Using agent, monitoring continually the learning process of learners 'inferencing to offer proper hints in case of incorrect answer in learning assesment, composing dynamically learning materials according to the learning feature and the evaluation of assesment, our system implements effectively adaptive instruction system. Moreover, appling the fuzzy concept to the system could naturally consider and ideal with various and uncertain items of learning environment thus could offer more flexible and effective instruction-learning methods.

This study is to suggest a method of constructing Informatics textbook considering the cognitive development level of middle school learners. We developed 3 types of learning content models according to the educational objectives and activities of learners and then suggested the methods of constructing textbook. For this, we reviewed the related research results on the development characteristics and cognitive development theories of middle school students. Second, we drew instructional schemes from the pedagogic theories. Then, we suggested 3 models: 'Learning Centered on Concept'. 'Learning Centered on Investigation', and ' learning Centered on Actual Training'. We suggested construction schemes to each model and verified the adequacy using questionnaire to 30 teachers and received the positive responses from most teachers.

The purpose of this study was to investigate to relation of necessity and practice of contents of clothing and textiles education(classify them into four units, choice and dressing of clothes, textile and management of clothes, design and sewing of clothes, knitting and embroidery). Method of posing a questionnaire is adopted to obtain stochastic data required for pertinent analysis. This is the investigation of which 400 (high school students 204, university students 196) girl students located in Choongnam and Junrabookdo province. In this statistical analysis, SPSS 10.0 for Windows Program was utilized to calculate percentage, mean and standard deviation. Also, these materials were verified by t-test, One-way Anova, Pearson's correlation coefficient. The results of this research were as follows. First, girl students' necessity mean point were higher than practice mean point about the contents of clothing and textiles education. And necessity had a positive relationship with practices of contents of clothing and textiles education. Second, there was a significant difference in necessity and practice of contents of clothing and textiles education according to demographic variables. These results should be provide fundamental information for improving students' critical practice in their real life. Since this study has touched only limited research on the topic of clothing and textiles education, it is essential that further research covering a wider array of themes be done in the future. this study has touched only limited research on the topic of clothing and textiles education, it is essential that further research covering a wider array of themes be done in the future.

"Euibangyoochui" is a great medical encyclopedia composed of 91 symptoms and signs of diseases which classified 150 kinds of reference books. It consisted mainly of fifty thousands of herbal prescriptions and therapeutics but it deals with other treatments like diet therapy, precautions, acupuncture and moxibustion, physical and breathing exercises as well. Unlike other medical references, this book made up these treatments as independent chapters. We tried to catch the meanings and characteristics of each chapters.

본 논문에서는 음성 신호에서 발성 화자가 바뀌는 시점을 자동적으로 찾아내는 화자변화 구간 검출에 대하여 연구하였다. 화자변화 검출을 위해서는 음성 신호에 나타나는 화자 개별성에 의한 차이만 비교해야 하는데 실제 환경에서는 화자들이 동일한 내용의 발성을 하지 않으므로 다른 발성내용에 의한 정보가 포함되어 검출 성능을 저하시킨다. 그러므로 각 화자의 개별특성만 강조되도록 발성내용에 포함된 음성학적 정보의 영향을 제거하는 방법을 통해 검출 성능을 향상시켰다.

본 논문에서는 JPEG 압축 이외의 블러링(blumng) 및 샤프닝(sharpening) 등의 허용 가능한 이미지 조작에도 정보가 유지될 수 있는 내용 적응(content adaptive) 서명(signature) 기법을 제안하였다. 제안한 방법은 블록의 이미지 내용의 특성을 사용하여, 기존의 이미지 블록 사이의 DCT 계수 차이가 유지되는 DCT를 기반으로 한 Chang의 서명 방법의 단점을 개선하였다. 즉, 허용 가능한 이미지 조작에 대하여 에러 발생 확률이 높은 블록을 피하여 서명을 생성하였다 Lenna를 포함한 여러 표준 영상을 사용하여 실험한 결과, 제안한 랑법은 Chang의 방법에서 발생하는 서명의 비트 스트림 에러보다 에러 발생 빈도가 블러링 이미지에서는 평균 약 55％, 사프닝 이미지에서는 평균 약 51％ 더 낮았다.

This study takes note on the need for the consideration of the relationship between the service contents and service space which libraries provide, since at the moment the demands of library users, purpose of using it, etc. gradually become varied. In this study, type classification of public libraries was done focused on the relationship between service contents and service space, targeting Japanese public libraries. Through linking approach between service contents and service space, the analysis of Japanese public libraries' characteristics and type characteristics could be captured. This study has ultimately aimed to prepare for the basic data which will help Korean public libraries to make connection between service contents and service space in the future. The collected service contents and service space had been analyzed by multi-dimensional data analysis methods such as the "Quantification Theory Analysis Type III" and "Cluster Analysis". After characters of libraries were analyzed, the findings of this study show the views such as "the field of information provided, the method of information provision, and the object of service provision." And types of 44 libraries are classified into those which have 6 kinds of characteristics as follows : (1) group-oriented libraries which provide the jobs and employment information, (2) libraries which provide the jobs and employment information through the counselling space, (3) individual-oriented libraries which provide the information of education-related fields, (4) group-oriented libraries which provide the information of education-related fields, (5) libraries which provide information focusing on the counselling space, (6) individual-oriented libraries which focused on the service provision.
