대강당 혹은 실외 특정 공간에서 음성을 원활하게 전달하기 위해서 음성지원 시스템을 사용할 수 있다. 특히, 강당과 같은 특정 실내 공간에서는 특성상 여러 명이 강의를 수강하므로 소음으로 인해 강의에 집중하는 다른 청강자들이 명확한 음성을 전달 받을 수 없다. 강의 지원 시스템이 구축 되어 있지 않은 장소에서는 비용 부담을 줄이면서 유용하게 활용할 수 있는 시스템이 필요하다. 따라서 본 논문에서는 공용 네트워크를 구축하여 각 휴대폰을 연결하고 메인 휴대폰을 통해 각 휴대폰으로 음성을 전달하는 음성 지원이 가능한 시스템을 설계 및 구현하였다. 본 시스템의 기능으로는 인상 깊은 강의나 공연을 저장할 수 있는 저장기능을 제공하며 개개인의 이어폰 통해 정확하고 명확하게 강의에 집중을 할 수 있다. 본 애플리케이션을 활용한다면 방송을 지원하는데 있어 무리가 있는 공간에서 효율적인 강의가 가능하게 하였다.

Purpose: The purpose of this study was to develop a lecture on oral presentation and to evaluate changes in anger expression, assertive behavior, and self-esteem after lecture on oral presentation. Methods: The design was a nonequivalent control group pretest-posttest design. The participants were university students in nursing, of which 17 were assigned to the experimental group and 15 to the control group. The education was carried out for 2 hours, once a week for 14 weeks. Data was analyzed with SPSS/WIN 14 program, and included chi-square test, independent t-test, and repeated measure ANOVA. Results: Lecture on oral presentation showed significant differences in the changes of anger expression (F=10.122, p=.003) and assertive behavior (F=8.498, p=.007). Conclusion: Findings suggest that this lecture on oral presentation was effective in changing students' anger expression and assertive behavior. Therefore this lecture on oral presentation is recommended for inclusion in education for university students in nursing.

본 논문에서는 Web Lecture script를 정의하고 이를 효과적으로 운영하기 위한 Java Web Server를 설계 구현하였다. Web Lecture Script란 강의록, 문제출제, 문제 평가, 숙제 제출, 자료실, 토론방 등의 가상 대학 환경을 편리하게 구축하기 위해서 데이터베이스 및 파일의 접근을 Web 환경의 script막을 사통하여 구현할 수 있도록 정의한 것이다. Lecture시스템은 사용자에게 정형화된 포맷이 많이 쓰이기 때문에 script로 정형화된 형태의 인터페이스가 적합하며, 실제적인 구현이 Jaya로 이루어지기 때문에 확장의 범위가 크다. Web Server는 이러한 Lecture Script를 사용자에게 제공하기 위한 Script Engine을 포함하고 있어야 하는데, 이러한 Script Engine이 Web Server라 어떻게 상호작용 하는가에 따라 성능이 좌우된다. 상호 작용하는 방법에는 Script Engine이 Web Server 자체에 포함될 경우, 독립적인 프로세서를 띄워서 처리하는 방법 스크립트만을 처리하는 별도의 서버를 두어 처리를 전환하는 방법이 있다. 따라서 Lecture Script 처리 Engine은 여러 방법으로 구현하고 성능을 비교하여 보다 효과적인 서버를 제안하고자 한다.

The demand for e-learning through video lectures is rapidly increasing due to its diverse advantages over the traditional learning methods. This led to massive volumes of web-based lecture videos. Indexing and retrieval of a lecture video or a lecture video topic has thus proved to be an exceptionally challenging problem. Many techniques listed by literature were either visual or audio based, but not both. Since the effects of both the visual and audio components are equally important for the content-based indexing and retrieval, the current work is focused on both these components. A framework for automatic topic-based indexing and search depending on the innate content of the lecture videos is presented. The text from the slides is extracted using the proposed Merged Bounding Box (MBB) text detector. The audio component text extraction is done using Google Speech Recognition (GSR) technology. This hybrid approach generates the indexing keywords from the merged transcripts of both the video and audio component extractors. The search within the indexed documents is optimized based on the Naïve Bayes (NB) Classification and K-Means Clustering models. This optimized search retrieves results by searching only the relevant document cluster in the predefined categories and not the whole lecture video corpus. The work is carried out on the dataset generated by assigning categories to the lecture video transcripts gathered from e-learning portals. The performance of search is assessed based on the accuracy and time taken. Further the improved accuracy of the proposed indexing technique is compared with the accepted chain indexing technique.

The purpose of this study is to examine perceptive change in attitude toward infancy and early childhood among university students' who were exposed to a human development lecture on infancy and early childhood. This study aims to investigate the significance of education in shaping attitudes related to child development and the importance of infancy and early childhood as developmental stages. This study also seeks to provide basic data for expanding and systematizing relevant educational programs. Fifteen university students who attended a lecture on human development were divided into four groups with three groups containing 4 members and one group containing 3 members. The following results were obtained: 1) Before attending the lecture on human development, students perceived infancy as a period dominated by feelings of helpless, indifference, and a general lack of knowledge or ability to interact with their environment; 2) Before attending the lecture on human development, students perceived early childhood as an initial period of transition that can potentially influence one's future; 3) After attending the lecture, students were better able to rationalize the developmental importance of infancy and early childhood. 4) After attending the lecture, students displayed broader understanding of the importance of early childhood on human development. This study also discusses the necessity for continuous and systematic provision of programs to help adults develop a positive perception of infancy and early childhood as a developmental process related to parenting skills.
