본 논문은 국내 소프트웨어 산업에 있어서 기업의 시장 활동과 관련된 특성을 분석하고 정부의 정책 및 역할을 분석하였다. Porter의 국가 경쟁력 모형을 기본 프레임워크로 하여 국내의 소프트웨어 산업에 있어서의 수요조건의 특성과 이에 관련된 관련 정책 방향을 점검하였다. 실증적 자료가 부족한 국내의 소프트웨어 산업을 대상으로 탐색적 성격의 시장 활동 분석용 설문을 작성하여 약 200개의 소프트웨어 사업자를 대상으로 설문을 수행하여 이들 사업자들이 느끼는 시장 활동의 특성을 분석하였으며, 이를 바탕으로 정부의 역할에 대한 정책적 시사점을 도출하고자 하였다.

The purpose of this study is to investigate the values and meanings of university libraries and library catalog in the learning activities of Korean college students. Discussed in details are unique features in their library use behavior and catalog search behavior, and critical factors influencing their behavioral characteristics. A qualitative approach was employed for data collection and analysis. Intensive interviews were conducted with 30 students, also utilized was tight and close observation of their library search behavior. The result of this study is on identifying the underlying reasons why Korean students use their libraries and catalogs in a passive and limited manner.

WTO 체제의 등장과 기술경쟁의 가속화로 기술의 확보가 기업경쟁력의 핵심으로 등장하고 있는데, 우리나라 정보통신 산업의 경우 민간부문의 기술개발 활동은 그 투자면에서 뿐 아니라 기술관리 측면에서도 취약성을 면치 못하고 있다. 이에 우리나라 정보통신산업체를 대상으로 연구개발전략의 실태를 조사하여 그 문제점과 개선대안을 탐색한다. 실태조사 결과 정보통신산업체들의 연구개발전략은 아직 전사적 차원의 "Total R&D"개념이 다소 부족하고 장기적인 관점에서의 연구개발 활동이 미흡한 것으로 나타나, 중장기기술개발계획과 연계된 전략적 연구관리체제의 도입이 필수적이다.

The present study investigates the seventh and the eighth graders' perception of Free Learning Semester Programs offered by libraries by developing a survey questionnaire on students' needs for Free Learning Semester Programs of Libraries. The skills that middle school students want to improve in Free Learning Semesters are career exploration skills, and the type of Free Learning Semester that is most intensively implemented is career exploration activities. Programs are often offered in the form of experiential classes. Regarding the activities that the students want to participate during Free Learning Semester, the most preferred activities included field experience activity in the career exploration domain, cooking class in the student choice program, smartphone app development in club activities, design activity in the art domain, the badminton in the physical education domain, and using iPad in the information use skills. In addition, among the library programs in coordination with Free Learning Semester, the students liked the occupational experience program most. Future studies need to include the development and implementation of Free Learning Semester Programs based on students' opinions, and investigate their satisfaction with the Free Learning Semester Programs offered by libraries.

This study interpreted film-creators' information behavior by reconstructing information behavior in the process of film-planning using human information behavior. Film creators exchange, collect, and analyze information through channels in the information environment so called "the small world." After these processes, they strategically express this information by creating a film. This study concludes that the purpose of film-creating activity and that of everyday life information seeking are intertwined and that co-communication is the most important information channel and information source.

This study was carried out for the purpose of Exploring the types of AI platforms for creative activities and how to use them. In order to learn AI in the fields of art creation and music creation, which are representative areas of creative activity, types of AI platforms that can experience AI and perform simple programming were investigated. In addition, the utilization plan was presented so that each AI platform can be used to express students' ideas abundantly and to enhance their creativity. Through this, it is meaningful to suggest that the AI platform can be used as a teaching aid to enhance students' expressive power and creativity in creative activities.

본 논문에서는 라이프로그 데이터를 기반으로 한 행동인식 결과로부터 일상생활의 활동유형을 분석하는 기술에 대해 제안한다. 실제 일상생활 중에 수집한 가속도 센서 데이터만을 이용하여 분석한 행동인식 결과를 정적-동적 행동으로 분류된 특징 벡터로 나타내었고, 이를 클러스터링하여 6개의 대표 활동유형으로 분류하였다. 50명의 사용자 데이터를 분석하여 정적-동적 활동의 비율에 따른 활동유형을 분류함으로써 실제 라이프로그 데이터로부터 일상생활 활동유형을 확인하였다.

This study analyzed scientists information behaviors when they engage in solving specific research problems in various situations throughout the entire scientific R&D lifecycle process. In-depth interviews with a total of 24 scientists were conducted in their research laboratories, the scientists' everyday workplace and the contexts of scientific research. The theoretical and methodological frameworks employed for this study were Dervin's Sense-making, Savolainen's Everyday Life Information Seeking, and Engestrom's Activity Theory. The findings of this study informed context-specific research and information behaviors of the scientists in the 14 sub stages of the five-stage of R&D lifecycle. Specifically, the study revealed the research objectives and related information behaviors (e.g., information needs, information seeking, information sources and channels, information barriers, etc.) to achieve the objectives at each sub-stage. The study results provided essential information to re-design the information services and strategies that accommodate the scientific R&D lifecycle.

In this paper, a variable motion estimation scheme based on HBMA(Hierarchical Block Matching Algorithm) to improve the performance and to reduce heavy computational and transmission load, is presented. The proposed algorithm is composed of four steps. First, block activity for each block is defined using the edge information of differential image between two sequential images, and then average block activity of the present image is found by taking the mean of block activity. Secondly, camera pan compensation is carried out, according to the average activity of the image, in the hierarchical pyramid structure constructed by wavelet transform. Next, the LUT classifying each block into one among Moving, No Moving, Semi-Moving Block according to the block activity compensated camera pan is obtained. Finally, as varying the block size and adaptively selecting the initial search layer and the search range referring to LUT, the proposed variable HBMA can effectively carries out fast motion estimation in the hierarchical pyramid structure. The cost function needed above-mentioned each step is only the block activity defined by the edge information of the differential image in the sequential images.

The purpose of this study was to identify the effect of clothing involvement, store and brand loyalty orientation on the information search behavior. The study subjects comprised 298 females living in Seoul and Kyung-gi area. The data were analyzed with factor analysis, regression, cluster analysis, ANOVA and correlation analysis. Clothing involvement and information search behavior consisted of various factors. Clothing involvement, store and brand loyalty influenced information search behavior. Fashion and clothing involvement was the most important factor which influenced all loyalty and information search behavior(i.e. brand and store loyalty, personal and nonpersonal information search behavior). According to store and brand loyalty factors, female consumers classified into three groups : low loyalty, brand loyalty and store loyalty group. Three groups showed different clothing involvement, information search, clothing purchasing behavior and demographic variables. Therefore, loyalty orientation is the important factor which can describe the consumer behavior more effectively.
