This study analyzed the trends and current status in public libraries in Korea for 14 years, focusing on the overview and facilities of public libraries using public library statistics from 2007 to 2020. The research data were collected from the National Library Statistics System and compared with the population and GDP per capita of Korea. As a result, the number of public libraries in Korea is 1,172 as of 2020, which has nearly doubled compared to 2007, and it was found that this increase has a very strong correlation with GDP per capita and population. There were 229 contracting out public libraries operating by the local government in 2020, and the contracting out rate increased from 18.8% in 2007 to 25.1%. Although the site area of public libraries varies greatly from library to library, it tends to get larger over time. The total floor area of public libraries operating by the Office of Education is larger than that of public libraries operating by the local government, and it gradually increases over time, but the total floor area of public libraries operating by the local government have decreased slightly. The total number of seats in the library is decreasing in all libraries, and the reading seats for children and the reading seats for the elderly and the disabled tend to slightly increase.

신경망을 이용한 추천 기술은 항목이나 사용자간의 가중치를 학습할 수 있고, 자료 유형에 상관없이 데이터 처리가 용이하다. 또한 최근 연구를 통해서 그 우수성이 입증되고 있다. 그러나 사용자간의 상관관계로 추천하는 사용자 신경망 모델과 항목간의 상관관계로 추천하는 항목 신경망 모델이 서로 다른 관점으로 다른 선호도를 제시한 경우에 선택한 모델의 선호도에 따라 시스템의 성능이 좌우된다. 그러므로 효율적이고 성능이 우수한 추천 시스템을 위해 사용자와 항목 신경망 모델의 통합 방법을 제안한다. 두 모델 사이에 우선 순위를 결정하여 통합하는 순차적 통합 방법과 두 모델을 동시에 고려하는 병렬적 통합방법을 제안한다. 그러나 두 통합 방법은 선호도 예측 기준에 있어서 정적이고, 문제에 대한 적응성이 없다. 그러므로 신경망(퍼셉트론, 다층 퍼셉트론)을 이용한 통합 방법을 제안한다. 또한 퍼지의 소속함수를 이용하여 퍼지 추론를 적용한 통합 방법을 제안하고, 패턴 인식 분야에서 사용하는 BKS 방법을 적응하여 두 신경망 모델을 통합하여 실험한다. 본 논문에서는 사용자와 항목 신경망 모델을 통합함으로써 기존의 추천 기술인 연관 규칙과 단일 신경망 모델을 이용한 추천보다 우수함을 보이고 있다.

XML/HTML 문서와 같이 트리 구조로 표현되는 데이터의 변화 탐지는 NP-hard의 문제로 이에 대한 효율적인 구현은 매우 중요하다. 본 논문에서는 효율적인 변화 탐지를 위해 트리 구조의 데이터를 X-tree로 표현하고 이에 기초한 휴리스틱 알고리즘을 제안한다. X-tree에서는 모든 서브트리의 루트 노드에 서브트리의 구조와 소속 노드들의 데이터들을 128비트의 해시값으로 표현하여 저장함으로 신ㆍ구 버전의 X-tree들에 속한 서브트리들의 비교가 매우 효율적이다. 제시한 변화 탐지 알고리즘에서는 구 버전의 X-tree의 모든 서브트리들에 대해 신 버전의 X-tree에서 동등한 서브트리들을 찾고, 이들에 기초하여 이동 연산이 발생한 서브트리들과 갱신 연산이 발생한 서브트리들을 순차적으로 찾는다. 이때 이동 연산과 갱신 연산으로 대응되는 서브트리는 동등 서브트리로부터 루트 노드로 대응 관계를 확장하는 가운데 발견된다. 이후 깊이 우선으로 검색하면서 나머지 노드들을 대응시킨다. X-tree의 구조적 특징에 기인하여 노드들 간의 비교를 통해 대응 여부를 검사하는 대부분의 기존 연구와는 달리 서브트리의 비교를 통해 대부분의 대응 관계를 결정하므로 효율적인 변화 탐지가 가능하다. 본 알고리즘은 최악의 경우에서도 N을 신ㆍ구 버전 문서의 전체 노드 수라 할 때 O(N)의 시간 복잡도를 갖는다.

In order to understand the trends of collaborative research in the field of Library and Information Science (LIS) in Korea, this study analyzed bibliometric data and keywords of 5,383 Journal papers by 195 Korean LIS professors from 2000 to 2017 as well as the author credit allocation formulas of 26 Korean university research evaluation criteria. Examination of university research evaluation criteria revealed co-authors' credit level to be generally much lower than that of single authors, which in turn reduces the relative value of collaborative research. As a result, recent journals publish more co-authored papers than single author papers both domestically and internationally. The study also found collaborative research to be less prevalent in private universities than national universities and least prevalent in associate professors among professors. Furthermore, keyword analysis of study data revealed the emerging topics of both domestic and international collaborative research to be those that reflect social phenomena as well as those that relate to information science employing new technologies.

The utilization of department information in bibliometric analysis using scientific and technological literature is highly advantageous. In this paper, the department information dataset was built through the screening, data refinement, and classification processing of authors' department type belonging to university institutions appearing in academic journals in the field of science and technology published in Korea, and the automatic classification model based on deep learning was developed using the department information dataset as learning data and verification data. In addition, we analyzed the co-authorship structure and network in the field of computer science using the department information dataset and affiliation information of authors from domestic academic journals. The research resulted in a 98.6% accuracy rate for the automatic classification model using Korean department information. Moreover, the co-authorship patterns of Korean researchers in the computer science and engineering field, along with the characteristics and centralities of the co-author network based on institution type, region, institution, and department type, were identified in detail and visually presented on a map.

The study used 'SPSS 11.0 FOR WINDOW - Statistical Package' to analyze the collected samples and dealt with data of 174 individuals. Statistical analysis of the research for hypothesis verification was about frequency, trust level, mutual relationship, variables, and T-verification. The meaningful level for any result was ranged within 95%(p< .05), 99%(p<.01). The finding are as follows. Effects on pleasure, one of elements of team spirits taken by instructor's training style are analyzed as follows. It was proved to be meaningful in relation with a series of activities like training, democratic, social, compensatory aspects and showed also considerable relation with power based behaviors. That says, players are found to enjoy high pleasure when social and bureaucratic behaviors of instructors are very energetic. In addition to that, training, democratic, and compensatory activities didn't show any meaningful effect. Team spirit was found to play a main role between instructor's behaviors and training, democratic, social rewarding activities. Democratic and social acts influence on team spirit. Looking into the detailed aspects, team spirit was resulted very high in the individuals with low democratic mind and was shown high group spirit by groups with high sociable activities. Teamworks was found to be affected by relation between instructor's acts and training, democratic, social and compensatory aspects and it showed meaningful relations with training, social, bureaucratic behaviors. Low degree of training and bureaucratic activities are found to prefer for power team spirit, and high social activities led a strong teamworks. Group binding spirit was influenced by training, democratic, social compensatory, bureaucratic behaviors and it showed to give effects on democratic, social, and bureaucratic activities of instructors. Low degree of democratic and bureaucratic behaviors are found to produce strong team spirit. In contrast with that, strong social activities was found to be motive of powerful team spirit. Value of team spirit was found to play a main role between instructor's behaviors and training, democratic, social, rewarding activities. It didn't show any meaningful effect on behavior of instructors.
