This study analyzed authors' use of theory in 654 articles that appeared in two core library and information science journals during last three decades. In order to analyze degree of theory use of LIS, such as, publication productivity, growth and distribution of theory in subfields. name and origin of theory, usability of each theory, subfields and journals, and so on, content analysis of LIS theories was performed through conceptual and empirical study. For the purpose of this study, we suggested a couple of new analytical methods, so called, ‘Subfield Classification Scheme’ within LIS, and ‘5 Degrees of Theory Use’ model for the first time.

The purpose of this study is to analyze the identity and relationship of library and information science by exploring theoretical aspects of LIS research, including theory building and theory use. The sample of this study consists of 1,661 research articles published from 1984 to 2003 in two Korean and two American core LIS journals. Theory articles are analyzed with two scales, such as '4-degree of theory efficiency' and '5-degree of theory use' Each article is coded in terms of journal, country, publication year, subfield, and methodology of the article. and affiliation, department, and research experience of the first author. The theories used therein are coded according to their origin and age. Also, an author co-citation technique is applied to represent intellectual structure on a two-dimensional map, which has been constructed by theory use of LIS authors fur 20 years.

The purpose of this study is to examine research trends on theory use in Korean LIS, and ultimately to identify its academic growth and change. This study conducted content analysis, with a sample of 344 articles in Journal of the Korean Society for Library and Information Science during the past five years from 2010 to 2014. Then longitudinal analysis was additionally carried out by comparing with a data set from 1984 to 2003. Findings are as follows. 13.7% of research articles used theories on average 2.02 times. The most theories were deployed at the level of Spot Citing and the next most theories were at the level of Theory Application. Research on the subject of education and information use/seeking used theories most frequently. Theories from LIS were 31.9% and those from social science were 58.3% of all. Also, longitudinal analysis results support the conclusion that there was no quantitative increase but was clear qualitative growth in theoretical research of LIS. And the current theoretical framework of LIS research has closer relationships with pedagogy and psychology among social science disciplines than in the past.

Lenstra 등에 의하여 LLL 알고리즘이 처음 개발된 이래 최근까지 격자 이론은 공개키 암호의 분석 및 안전성 증명에 광범위하게 이용되어지고 있다. 초창기 Knapsack 계열 암호의 분석에 부분적으로 활용되었던 격자 이론은 1990년대에 인수분해, Diffie-Hellman, 격자 기반 공개키 암호로 그 분석 적용 분야가 확대되었고, RSA-OAEP를 비롯한 여러 암호 시스템들의 안전성 증명 등에도 중요한 도구로 활용되었다. 본 논문에서는 암호학의 도구로 활용되는 격자 이론의 개요를 살펴보고, 공개키 암호 분야의 분석에 있어 격자 이론이 활용된 사례들을 각 분야별로 결과 위주로 소개한다.

The purpose of this study is to examine the development of theory of mind on the story sharing with picture books. The subject of this study is 38 five years olds children who are attending C kindergarten in J city, Jeollabuk-do province. It was executed that an twelve sections of storytelling with picture books during six weeks. The storytelling activities were performed with predicting and listening of picture book contents, problem situation knowing and story sharing, feeling of the character mind condition, and activities evaluating. The results were as follows. First, the story sharing with picture books were significantly different between the groups on the development of mind. Second, the story sharing with picture books including theory of mind were effective on the perspective taking ability. The results showed that the story sharing with picture books was effective teaching and learning method.

Based upon the assumption that both theory building and theory use are intertwined to construct a cohesive body of knowledge in the filed, this study attempts to identify the state of theoretical framework by examining the number and the quality of theoretical articles by subfield. Theoretical article is characterized as an incident in which in which the author contributes to the development or the use of theory in his/her own paper. Theoretical incidents were identified by a content analysis of 1,661 articles in four LIS journals from 1984 to 2003. The findings suggest that the four subfields, such as information seeking/use, information retrieval, library management, and scholar communication had great contributions to both theory building and theory use. Also, two research areas such as bibliometrics and professionals are very likely to be theoretical. Further, the analysis of the name of theories used by subfields could give an insight into the understanding of how the theoretical frameworks of each subfield are related.

Adolescent delinquency is a substantial social problem that occurs in both offline and online domains. The current study utilized random forest algorithms to identify predictors of adolescents' online and offline delinquency. Further, we explored the applicability of classic delinquency theories (social learning, strain, social control, routine activities, and labeling theory). We used the first-grade and fourth-grade elementary school panels as well as the first-grade middle school panel (N=4,137) among the sixth wave of the nationally-representative Korean Children and Youth Panel Survey 2010 for analysis. Random forest algorithms were used instead of the conventional regression analysis to improve the predictive performance of the model and possibly consider many predictors in the model. Random forest algorithm results showed that classic delinquency theories designed to explain offline delinquency were also applicable to online delinquency. Specifically, salient predictors of online delinquency were closely related to individual factors(routine activities and labeling theory). Social factors(social control and social learning theory) were particularly important for understanding offline delinquency. General strain theory was the commonly important theoretical framework that predicted both offline and online delinquency. Findings may provide evidence for more tailored prevention and intervention strategies against offline and online adolescent delinquency.
