The purpose of this study is to analyze the needs for developing a curriculum for strengthening the long-term care service expertise and job competency. Specifically, the researchers analyzed previous studies on national long-term care services and national policy data, and conducted focus group interviews with 14 experts from related agencies. Activity theory was applied as a framework for analysis and a questionnaire about the importance and difficulty of subjects from 25 long-term service employees was administered for validating the results of the qualitative data analysis. The upper part of the subject-goal-tool of the activity system was considered the main area of action, and the following rule-community-division was divided into contextual parts for action, and the implications for demand analysis and future operation of the online curriculum are summarized. In total, six courses were required for development. These courses could be applied to as a learner-centered flip learning for long-term care service workers and various educational methods of collective education and supplementary education have been proposed. Based on the study results, implications in the educational field for effective management of courses were suggested at the end of the study.

교원의 핵심 역량 중 지식 역량이나 수행 역량 등은 교직과정 이수 결과의 확인이나 지필 시험 또는 실기 시연 등을 통해 확인 또는 평가할 수 있다. 그러나 태도 역량이나 전문성 개발역량의 일부 요소들은 별도의 도구나 평가로 심사해야 된다. 전문성 개발 역량 가운데 자기반성 노력, 지속적 학습 노력, 교육 공동체 간 의사소통 및 협력 등의 요소들은 기존의 평가 방식으로 파악하기 어렵다. 따라서 교원의 핵심 역량을 평가하기 위해서는 교직 적성 및 인성 검사와 같은 별도의 도구가 필요하다. 본 논문은 교원자격을 강화하기 위한 교직 적성 및 인성 검사를 효율적으로 실시하기 위한 온라인 웹 검정 시스템을 설계하고자 한다.

Collaborative filtering technique is a major method of recommender systems and has been successfully implemented and serviced in real commercial online systems. However, this technique has several inherent drawbacks, such as data sparsity, cold-start, and scalability problem. Clustering-based collaborative filtering has been studied in order to handle scalability problem. This study suggests a collaborative filtering system which utilizes genetic algorithms to improve shortcomings of K-means algorithm, one of the widely used clustering techniques. Moreover, different from the previous studies that have targeted for optimized clustering results, the proposed method targets the optimization of performance of the collaborative filtering system using the clustering results, which practically can enhance the system performance.

The purpose of this study was to investigate the perceptions of faculty as a foundation for establishing a convergence education model at N-University. In September 2019, a survey was conducted using an online survey system, and a total of 80 responses were obtained. SPSS 23 was used for analysis, and a t-test, ANOVA, and multiple regression analysis were performed. First, the female faculty were significantly more positive about linked-major expansion than were the male faculty. Second, assistant faculty were significantly more positive about convergence curriculum establishment than were associate faculty. Third, as a result of the multiple regression analysis, the preference for multimajor expansion was the most significant and positively influencing factor on the convergence curriculum establishment. Universities must provide various incentives to form a consensus among university faculty. The Ministry of Education must support individual universities through the establishment of clearer guidelines and a kind of convergence education support center.

학교의 학습 과정에 있어서 학습자 간의 학습 능력의 차이는 존재하며 이를 해결하기 위해 교육과정에서는 개별 학습과 수준별 학습을 권장한다. 유무선 인터넷을 통한 수준별 학습은 최근에 많은 연구가 되고 있는 u-러닝(Ubiquitous Learning) 환경에도 부합하며 학습자 개개인이 자신의 속도와 수준에 맞게 자기주도적으로 학습을 하기에 알맞은 방법이라 할 수 있다. 이에 본 연구에서는 학습자가 시간과 공간에 구애받지 않고 자율적으로 수준에 맞게 학습할 수 있는 수준별 학습 시스템을 설계하였다. 특히 시스템에 체계성을 더하기 위해 개별화 학습 체제 중에서 과거 많은 연구를 통해 그 효과성이 입증된 Keller의 PSI(Personal System of Instruction) 이론을 활용하여 시스템의 각 과정을 설계하였다. 본 시스템의 장점은 다음과 같다. 첫째, 학습자가 원하는 시간과 공간에서 자신의 속도에 맞게 학습할 수 있으므로 자기주도적인 학습 능력을 기를 수 있다. 둘째, 시스템 구성상 평가를 통해 일정한 기준에 미달하면 목표에 도달할 때까지 계속 학습하고 도전해야 하므로 궁극적으로 완전학습에 도달할 수 있다. 셋째, 제한된 교실 상황에서 벗어나 온라인에서의 학습 지원이 가능하므로 학습자의 개인차에 따른 수준별 학습을 관리하고 책임져야 하는 교사의 부담을 덜어준다.

Individual studying that compose knowledge and improve efficiency of studying through collection of information by various class strategy which takes advantage of web, and Cooperative learning that can elevate sense of responsibility and solve the problem through communication with another person have been developed actively. But, individuation tutoring materials that is developed present doesn't fit of causing learner's interest, and stimulating curiosity about problem because mostly studying is gone in presentation form. Also, cooperative learning materials are lacking connection with actual course of education, application is difficult in real class spot. So, this research has applied self-directed learning, centered with interested operation activity, aimed at improvement in various thought. Also, we have developed social studies tuition-learning system, purpose to the management is possible with on-line project studying which could improve mind-decision ability and ICT application ability. This system is developed for flexible management could be possible in various class circumstance, and level learning could be done through accomplishment-test and the result could be applied by feedback process.

Over the past 70 years, movies and television have revolutionized the way people communicate. However, even with this development, TV has been used only as a means of communication targeting an unspecified number of people due to the restriction of media such as radio waves and movies. However, the development of the Internet and online video has come to a time when 100 million people watch YouTube videos uploaded from the other side of the world by eliminating these restrictions. The message that you want to deliver now can be delivered to anyone, but making the image with these messages remains the last obstacle to communication. To solve these problems, we implemented a web application and a video production program through AWS. This system basically provides the administrator with the video production through the easy interface, the information management and the program on the server on the internet through AWS, the assigned lecture including the computer and the smart phone, the learning materials, And implemented to increase the efficiency of educational video production service.

기존의 도서관 정보서비스는 도서관 업무담당자에 의한 1:n 방식의 온라인 지식서비스만을 강조하였다면 스마트 도서관시스템에서는 빅데이터를 통해 지식을 생성, 검증, 분류하여 지능형지식, 실감형지식, 맞춤형지식, 체험형지식 등을 제공할 수 있다. 또한 빅데이터를 활용한 다자간 콘텐츠 공유, 상호 의견 교환이 가능하며, 집단지성에 의해 구축되는 학습 콘텐츠 및 지식 베이스는 국가의 지식자원 경쟁력을 향상시킬 수 있으며, 차세대 이러닝 환경에서의 지능형 튜터링을 통해 창의적 인재육성, 공교육의 질적 향상, 사교육비 절감, 교육 기회 균등 배분, 지역 및 계층 간 위화감 해소 등 국가정책 목표 실현할 수 있다. 제안된 빅데이터 기반의 스마트도서관 정보서비스시스템에서는 멀티테넌트 환경에서 구현이 가능한 핵심요소들을 개발하였다. 그러므로 초기 투자비용이 거의 없고, 쉽고, 간편하며, 저비용 IT 서비스가 가능한 SaaS 기반의 소프트웨어 온-디멘드 방식의 서비스 모델로 시스템을 구현하였다. 또한 연결방식으로는 N고객:1인스턴스, 제공 프로그램은 동일한 코드 사용, 커스터마이징은 고객이 테넌트별 환경 설정을 통해서 직접 수정가능, 데이터는 테넌트별 자료를 공유해서 사용할 수 있으며 기존의 디지털도서관 시스템 서비스의 단점을 해결할 수 있도록 성능을 개선하였다.

This study analyzes the performance of flipped learning, an offline class method conducted in a degree-linked work-learning parallel system. Training in the work-study parallel system, which is conducted as part of job competency improvement, has thoroughly adhered to the offline method, but in line with COVID-19, unlike before, it is changing in the direction of using the online method more actively. However, educational methods such as flipped learning are not new because the degree-linked operation is applied to the academic system and education method of universities and is practically the same form as general university education. Therefore, it is necessary to analyze the educational performance and complementary points of flipped learning, which has recently been expanded in the degree-linked work-study parallel system, considering the characteristics of this system, in which classes are held only on weekends. As a result of statistical analysis based on the survey, some of the outcomes of flipped learning have been confirmed, and in order to increase the performances, it is necessary to continuously seek out specific measures to encourage learning and expand communication between instructors and students.
