Recently, interest in AI tutors is rising as a way to bridge the educational gap in school settings. However, research confirming the effectiveness of AI tutors is lacking. The purpose of this study is to explore how effective learner characteristics and recommended item learning activities are in predicting learner's academic performance in an adaptive online learning environment. This study proposed the hypothesis that learner characteristics (prior knowledge, midterm evaluation) and recommended item learning activities (learning time, correct answer check, incorrect answer correction, satisfaction, correct answer rate) predict academic achievement. In order to verify the hypothesis, the data of 362 learners were analyzed by collecting data from the learning management system (LMS) from the perspective of learning analytics. For data analysis, regression analysis was performed using the regsubset function provided by the leaps package of the R program. The results of analyses showed that prior knowledge, midterm evaluation, correct answer confirmation, incorrect answer correction, and satisfaction had a positive effect on academic performance, but learning time had a negative effect on academic performance. On the other hand, the percentage of correct answers did not have a significant effect on academic performance. The results of this study suggest that recommended item learning activities, which mean behavioral indicators of interaction with AI tutors, are important in the learning process stage to increase academic performance in an adaptive online learning environment.

본 연구는 2014년도에 조사가 완료된 한국아동패널 자료를 활용하여 자아발달, 사회성발달, 학습준비도, 학업능력의 잠재변수에 대한 관계를 분석하고 학령전기 아동의 학업능력에 영향을 미치는 요인을 찾아내는 것이다. 본 연구 대상은 한국아동패널 7차(2014년도) 자료의 2150가구 중에서 해당 자료의 미응답자와 시스템 결측치 1037가구를 제외한 1113가구의 초등학교 취학전 만 6세의 아동들이다. 연구 모델의 경로 효과를 분석한 결과 자아발달과 학업능력 사이에서 자아발달이 학업능력에 직접적인 영향을 미치는 동시에 사회성 발달과 학습 준비도를 매개로 한 간접적인 영향에도 유의미하게 나타났다. 그리고 학업능력에 미치는 자아발달, 사회성발달, 학습준비도 중에서 학습준비도가 가장 큰 비중으로 영향을 미치는 것으로 나타났다. 결과적으로 학령전기 아동의 학업능력은 창의력과 문제해결능력을 겸비한 인재로 육성하기 위해서 학습준비도가 매우 중요하게 다루어져야 한다는 것이다.

본 논문에서는 사업의 성공적인 운영을 위한 IPP 운영시스템 구축 사례를 제시한다. 2018년 4기 IPP 운영대학에 선정된 이후 1차년 사업수행을 위해 학사제도와 포털시스템을 구축하였다. 학사제도는 사업운영 규정과 기존 참여대학을 벤치마킹(benchmarking)하여 정규학기와 계절학기가 연계된 4학기제를 기반으로 한 학생 참여의 용이성에, 포털시스템은 학생-기업 매칭과 교내 각종 DB와 연동한 사용 편의성을 위해 맞춤형에 초점을 두고 설계되었다. 구축된 운영 시스템을 적용한 1차 년도 운영은 사업관리기관에서 시행한 실태조사의 많은 항목에서 운영시스템에 만족도가 전국 참여대학의 평균값을 초과하는 결과를 나타냈다. 실태조사 결과를 분석한 후 개선방향을 설정하였다.

The purpose of this study is to examine the organization of the standard liberal arts curriculum in accordance with the academic credit bank system (ACBS). With the growth of the system, the standard curriculum of the ACBS turned out to have many problems which have to be solved for securing and maintaining the quality of the system. In an attempt to improve the standard liberal arts curriculum of the ACBS, the study analyzed the problems of standard liberal arts curriculum of the ACBS according to three criteria: the organization of subjects in the six liberal arts curriculum areas, the completion of liberal arts and the exchange subjects between majors and the liberal arts. Based on the results of the analysis, the study suggests ways to improve standard liberal arts curriculum. In the future, research needs to be conducted to explore ways to implement the proposed standard liberal arts curriculum of the ACBS in real contexts.

Today, citation index information is used as an outcome scale of spreading technology and encouraging research. Article citation information is an important factor to determine the authority of the relevant author. Google Scholar uses the article citation information to organize academic article search results with a rank algorithm. For an accurate analysis of such important citation index information, large amounts of bibliographic data are required. Therefore, this study aims to build a fast and efficient system for large amounts of bibliographic data, and to design and develop a system for quickly analyzing cited information for that data. This study also aims to use and analyze citation data to be a basic element for providing various advanced services to the academic article search system.

While numerous studies have suggested the significance of uncertainty during the process of information-seeking, less research has investigated user uncertainty in the actual search process using a real system. This study investigated user perceptions of uncertainty in the process of the selection of information retrieval system in the real information-seeking process. Considering the role of commercial Web search engines as supplementary tools for traditional bibliographic databases in academic research environments, this study analyzed the selection behavior of scholarly researchers, who use such search tools for their academic study. The researchers were limited to the discipline of science in order to understand user perceptions in this field. The findings revealed various dimensions, types, and incidents of uncertainty. Variations appeared in different incidents of uncertainty relating to the unique characteristics of the subjects' information-seeking context. The identification of three principal origins of uncertainty based on the different types of uncertainty generated implications to improve information systems and services.

Scattered satellite images were collected and converted from TDF to HDF as a standard format. We reviewed all the metadata on the images domestic and abroad and set up the metadata for the meteorological satellite images and naming rules in KMA. The satellite information search system that meteorological satellite images were in service with metadata for public and academic fields was implemented for quick search and download. This system will facilitate satellite images for various academic purposes beyond KMA and management functions of the system make routine workflow to manage satellite images in an ease and standardized way.

Shu-gyo-ryoku, a program to enhance students' academic and career skills, was begun in the academic year 2011. Under the new program, "Career Planning" and "Career Design" were introduced as part of the liberal arts education for incoming freshmen. Approximately 500 students majoring in engineering enrolled in "Career Planning" in which they study a "curriculum map" and how it relates to their future fields of employment. The curriculum map illustrates the connections between classes and increases students'understanding of the curriculum structure. In small groups, students discussed the curriculum in order to develop sketches of their career paths. In addition, students answered a career anchor test and though several communicative activities, improved their communication skills. A portfolio system was built into the university network to record the learning history of each student. Students are able to check their learning histories and reflect on the change in themselves during their academic careers.
