작년 한 해 동안 국내 정보보호분야에서는 악성코드의 증가, 정보통신망법 개정, i-PIN 도입 등 커다란 사안이 많았다. 특히 통합보안솔루션의 부상과 시장 확대가 국내외의 화두가 되기도 하였다. 본고에서는 작년 국내외의 보안 기술 동향에 대하여 회고하여 보고, 금년 한 해 동안의 전망에 대하여 시만텍 등의 분석 보고서를 중심으로 기술하고자 한다. 이를 통하여 효과적인 보안 기술의 연구개발과 정책 수립에 지침이 되었으면 한다.

The purpose of this study was to look into trends in research concerned with children's counting in Korea. A total of 59 studies on counting including journal articles, master's & doctoral theses were analyzed in terms of the period of time, content, and research methods. The results showed that 1) ${\frac{1}{3}}$ of the total studies on counting were published in 2001~2005, 2) the most frequent content was the developmental trend of young children's counting ability and then the relation between counting ability and various mathematical competence, 3) most of the studies targeted normal early childhood children from 3~5 years old and used the quantitative method. These results showed that the domestic research on counting have limits in the research topics, subjects, and methodology. The researcher presents three suggestions for further research. Frist, topics that are not enough revealed in the previous studies, for examples, counting backwards, counting by collections such as tens, fives, twos, and counting errors in young children need to be further studied. Second, counting behavior and ability of young children under 3 years olds need to be investigated. Third, there is a need to increase the studies using qualitative methods.

This study has analyzed the trend of the quantitative research by analyzing domestic dissertations on information literacy that were published since 2000. The procedures, regulations, and descriptive elements of the quantitative study were compared and analyzed for this study. In addition, the study used 5 variables and criterions to measure these items. Based on the calculations, the study has examined the general characteristics of the thesis, research method, sampling method and sampling population of the dissertations. The study has also analyzed the trend of the measurement variables by categorizing the characteristics by published year and majors. Furthermore, the study has also presented the trend of the usage of statistic analysis method on research purpose by classifying the method into each purpose.

The purpose of this study was to analyze the trends of domestic research on mathematics teacher education in terms of timings, topics, methods, and subjects. For this purpose, a total of 111 articles dealing with mathematics teacher education, published since 1992 by the Korea Society of Educational Studies in Mathematics, were analyzed. The results of this study showed that the number of such articles has been rapidly increased since the late 2000's. Research on the professional development for teachers has been the most frequent topic but the studies dealing with teacher knowledge or orientation tend to be popular. Qualitative research methodology, specifically case study, has been most frequently employed in studying mathematics teacher education. The subjects for research included a similar portion of in-service and pre-service teachers, and elementary and secondary school teachers. Given these results, this paper closes with several implications for future research direction on mathematics teacher education.

This study reviewed and ascertained policy researches relating to the Internet in the field of communication. With using a meta-analysis, this study attempts to classify 44 academic papers from 2000 to 2009 by research theme, methodology, theoretic rationale, related sub-theme, and targeted service and area. It is found that the themes of preceding researches examined herein were limited to the 4th domain in Developmental Model of Media Research. Such researches mainly relied on exploratory studies and only a few of them addressed theoretic rationales. Also, most of Internet regulation discussions focused on content regulation and general internet service. Lastly, researchers discussed laws having bearing on the Internet and social-cultural issues of the Internet.

This study aims to provide basic data for revitalizing creativity research related to early childhood teachers by analyzing creativity research related to early childhood teachers. For this study, 103 master's and doctoral dissertations in Korea, which were searched through the National Assembly Library and the Research Information Sharing Service (RISS), were selected under the themes of 'early childhood teacher', 'creativity', and 'creativity research trends'. The frequency and percentage were calculated by analyzing creativity research related to early childhood teachers with five criteria: research period, research content, research method, research subject, and creativity factor. As a result of the study, first, as for the trends of creativity research related to early childhood teachers, 91 master's theses (88.3%) and 12 doctoral theses (11.7%) were conducted from 1991 to 2022, focusing on master's theses. Second, trends by research content were found in 20 basic studies (19.4%) and 83 practical studies (80.6%). Creativity research related to early childhood teachers is being actively conducted centering on practical research. Third, trends by research method showed 96 quantitative studies (93.2%), 7 qualitative studies (6.8%), and 0 literature studies (0%). Creativity studies related to early childhood teachers were being conducted with a focus on quantitative research. Fourth, the trend by research subject consisted of 100 studies (97.1%) related to early childhood teachers and 3 studies (2.9%) related to pre-service early childhood teachers. Fifth, trends by creativity factor were found in 56 studies (54.4%) related to teacher's variables and 47 studies (45.6%) related to creativity education methods. Studies related to teacher's variables were relatively higher than creativity education methods. As a result of this study, there is a lack of Christian education research in creativity research related to early childhood teachers, so it is expected that it will be done in the future.
