The purpose of this qualitative case study is to understand how the idea of data view and information graphics is used in the social studios middle school textbooks. Data were collected through national curriculum documents and social studies middle textbooks for 7-9 grades. We set up three questions for this studies; what kinds of information graphics are used in the textbooks, how the graphics are organized in the social studies middle school, and how the 7th social studies curriculum is related with the 7th national mathematics curriculum. Through the data analysis, we found that 1) Photographs, illustrations, information maps, etc., are used and frequencies of their usages are in descending order, 2) double lines graphs, circle graphs, and stripe graphs nip often adopted for the comparison of populations, 3) the relation of the two subjects curricula is not so good, especially in the curriculum steps of information mads scatter diagrams, and comparison of populations. Finally we suggest that new web site of data view or information graphics be provided for two curricula, workshop of information graphics are needed for social studies teachers.

The purpose of this study is to investigate the research trend of information user studies. The following findings are made. The literature on information user studies during 1980-1990 reveals 120 titles. The faculty members of university tend to publish their results in scientific journals and university publication while non-faculty members are more likely to represent their research papers in unpublished master thesis and bulletin. Subject distribution of research were classified into ten: user studies, material use studies, information needs and uses, user education, library use pattern, citation analysis, journal use, catalog use, information system, non-use study. Survey research, literature research, survey reserch and literature research use jointly, experimental research and citation analysis were employed for information user studies.

The purpose of this qualitative case study is to understand how the idea of data view and information graphics is used in the social studies high school textbooks. Data were collected through national curriculum documents and social studies middle school textbooks for the 10th grade students. We set up three questions for this study; what kinds of information graphics are used in the textbooks, how the graphics are organized in the social studies middle school, and how the 7th social studies curriculum is related with the 7th national mathematics curriculum. Through the data analysis, we found that 1) photographs, information tables, illustrations, etc., are used and frequencies of their usages are in descending order, 2) double lines graphs, and stripe graphs are often adopted for the comparison of populations, 3) the relation of the two subjects curricula is not well developed, especially in the curriculum steps of information maps, scatter diagrams, and comparison of populations. Finally we suggest that new web site of data view or information graphics be provided for two curricula, workshop of information graphics be needed for social studies teachers, and modification of the 7th probability and statistics curriculum.

There are two broad classes of user studies, in terms of their purposes or a n.0, pplications. One class might be termed basic studies, in which the purpose is to create or obtain knowledge regarding information needs and uses with no particular a n.0, pplication. The second type of study might be termed a n.0, pplied. The aim of second type is preparing standards to evaluate and improve existing information systems or to design new systems. The trends of user study tend toward basic research from a n.0, pplied ones. Furthermore, not only the broad-based studies change with special setting up and subdivided studies, but also the scopes of user study vary social scientist, human scientist, and even common users from limited natural scientists and technologists earlier. The aims of this paper is to summarize continuously pointed problems of user studies and to survey the state of the arts by reviewing the trends of user studies. The major problems of user studies are terminology, conceptualization, and methodology. These terms are essential to this study, and very important to decide the research fields and to select a method of survey, respectively. And in order to predict the user needs, studies of 'information needs' are inevitable instead those of 'information demands' which principally studied till nowadays. On the other hand, to reduce the problems of user studies, it is needed more qualitative studies ever than before and cooperation with other areas, for example, behavioral 'science, psychology, communication science and so forth.

상황인지(Context-awareness)란 사용자의 상황을 인지하여 이를 통해 사용자에게 적합한 최적의 정보를 제공하는 것으로 현재 많은 연구가 진행되고 있다. 이미 상황인지를 위한 프레임워크들이 존재하지만, 작은 메모리가 요구되는 제한적인 하드웨어 상황에서 적용하기에 적합하게 설계된 프레임워크는 흔하지 않다. 이에 대한 문제점을 인식하여 하드웨어 리소스가 부족한 상황에서 빠르게 동작할 수 있는 프레임워크를 구상하여, 기존과는 다른 제한적인 환경 안에서 상황인지를 통해 사용자에게 맞는 최적의 서비스를 판단, 제공하는 모바일 오브젝트를 설계하였다.

비유창성(disfluency)은 문어와 같이 정연한 구조로 말하지 못하는 현상 전반을 지칭한다. 이는 구어에서 보편적으로 발생하는 현상으로 구어 의존 구문 분석의 난이도를 상향시키는 요인이다. 본 연구에서는 비유창성 요소 유형을 담화 표지, 수정 표현, 반복 표현, 삽입 표현으로 분류하였다. 또한 유형별 비유창성 요소를 실제 말뭉치에서 어떻게 구문 주석할 것인지를 제안한다. 이와 같은 구어 데이터 처리 방식은 대화시스템 등 구어를 처리해야 하는 도메인에서의 자연언어이해 성능 향상에 기여할 것이다.
