The current study investigates major factors which influence the acceptance of mobile internet services based on the theoretical backgrounds of the technology acceptance model(TAM) and the flow theory. This research extended the Davis' TAM model(1989) by including the flow concept as another major factor towards the intention to use the mobile device in order to explain the acceptance of divers mobile services. According to the marketing studies(Ghani & Desphande, 1994; Novak, Hoffman & Yung, 2000), flow is regarded a psychological state in which one is absorbed in something he or she is doing, and is known to be widely adopted in explaining one's acceptance in the area of game, sports, and even hobby. This study developed a research model to explain the use of mobile services employing usefulness, ease of use and flow as major research variables, and collected 221 survey responses from the high school students who had experiences with such mobile services as game and audio file download. The results of the current research indicates that usefulness and flow influence the intension to use mobile services, but the effect of ease of use did not appear significant to the intention to use. It was also found that flow affects both usefulness and ease of use, and then ease of use next influences usefulness.

In this study, a database was established by analyzing the record data research produced in ice hockey sports. The deployed data verification with Ice hockey reference service was demonstrated with ice hockey officials and players. This research utilized the data stored in the KNSU Datanest data repository and developed PDF parsers for batch processing of records. Among the types of records, the game summary, team roster, team statistics, and player statistics files were collected, and tables were extracted from the records. PDF records were converted to text in CSV format which are converted to DataFrame and loaded into the database. Out of the total 22 types of records, 4 types were constructed with OO data parsed as element values. Data verification has found no problems with the quality of the data deployed, showing a high satisfaction with providing 66 factors against the 30 factors provided by the service previously used.

일본 문부과학성에는 21세기를 이끌어갈 어린이들에게 필요한 것을 '사는 힘'이라고 정의하였으며, 이를 위해 '신 학습지도 요령'을 개발하여 2011년부터 초등학교에 적용하고 있다. 변화하는 교육현장에 대응하기 위해 정보교육과 관련하여 2010년에는 '신 성장 전략 회의'를 실시하였으며, '교육 정보화에 관한 지침서'를 공표하였고, 2011년에는 '교육에서 ICT를 활용하기 위한 방향'이라는 연구를 통해 내용체계가 구성되었다. 특히 초등학교에서는 각 교과에서 정보교육을 통합하여 필수내용으로 실시되고 있으며, 이는 중등교육에서 본격적으로 시작되는 정보교육을 준비하기 위한 과정이라고 하였다. 이와 같은 초, 중, 고등학교가 연계된 정보교육의 일원화된 교수 학습방법과 정보과학적 사고를 토대로 이루어진 정보교육이 우리나라의 정보교육의 방향에 미치는 시사점이 크다고 할 수 있다.

Living in the Information Age, schools and teachers are expected to utilize new information technology in education to make teaching more effective. In Japan, the Ministry of Education, Culture, Sports, Science and Technology (MEXT) has been strongly implementing policies to promote information education (IE) in schools since 1988. According to a survey in 2005 (Japan MEXT, 2005), 100% of high schools in Japan at present have computers and the Internet connections. However, videoconferencing systems have only been introduced only in a small number of schools. This paper is the result of a pilot research to see the effects of using a videoconferencing system in a Japanese high school. The purpose of the research was to clarify the effects of introducing videoconferencing system in a Japanese high school and of utilizing it for conferences with other schools abroad on the studies of global issues. The target students were in the 12th Grade in the year 2006. The counterpart school was an Australian high school in Sydney and the conferences were held in English. International discussions on global warming were conducted between the Japanese and Australian students. Affective competence and cognitive competence were measured using questionnaires and worksheets given to students both before and after the videoconferences. The results showed that both cognitive and affective competences rose after each videoconference. Not only the students who actively participated in the conference but also those who were in the audience showed positive effects. In the field of international cooperation on global issues, especially, the effects were large. These results suggest that in order to teach global issues in which international effort and cooperation are needed, direct contacts with foreign students are effective in increasing student cognitive and affective competences. On the other hand, as English was the main communication tool in the conferences, Japanese students faced a certain difficulty in communication. Also, teachers, especially English teachers, were required to make great efforts to assist students in preparing for the conferences. The effectiveness of an international videoconference depends largely on students' English skills and teachers' efforts.

In this era of convergence, which is characterized by the integration and combination of technology and industries, broadcasting and communications, offline and online, and devices and services, the content industry is also experiencing rapid changes including inter-genre exchange, the creation of new industries, and customized demand. Specifically, IT-based digital content industries such as the online game, e-book, mobile contents and web portal industries are no longer restricted to the boundaries of video, music and games but are being expanded into the realms of education, medicine, fashion and sports thanks to CT innovation of 3D, CG, AR/VR, VFX, etc. As such, various countries have come to recognize the convergent content industry as a new growth engine that will pick up where the IT industry left off, and are forming policies for its development accordingly. This research aims to optimize the system of content taxonomy which is currently genre-focused and unable to support technological development and convergence, and to discover and select star contents to be rigorously developed with governmental support. In this paper, 20 star contents in 8 areas were selected, and these are expected to create tremendous cultural and economic value through ongoing technological and industrial development.
