본 논문에서는 유아교육기관에서 유치원 교사들이 멀티미디어를 활용하는데 있어서 학습 능력 향상 및 소프트웨어 활용 기술을 향상시키기 위해 플립러닝을 진행하도록 한다. 이를 통해 최신 멀티미디어의 특성을 잘 활용한 교수자의 강의 보다는 플립러닝을 위한 참여자 위주의 수업을 진행한다. 새롭게 등장하는 멀티미디어 기술을 접해야 하는 과목의 특성과 창의적이고 융합적인 인재를 양성해야하는 유치원 교사의 역할을 접목하여 미래 사회를 이끄는 유아들에게 효율적인 학습이 이루어지도록 하는 데에 큰 의의를 둔다. 유치원 교사들은 멀티미디어를 활용한 교수매체 활용 능력을 향상시키는 것은 물론이고, 최신 미디어 기술을 수업에 적극 활용하여 4차 산업혁명 시대의 흐름에 맞는 교과과정을 운영하도록 한다, 따라서 본 연구는 유치원 교사들을 양성하는데 있어서 미디어 교육의 중요성을 알리고 이를 교과과정에서 운영할 수 있도록 플립러닝을 활용한 교육과정을 제시하고자 한다.

With the coronavirus outbreak in China at the end of 2019, a global pandemic, most universities held non-face-to-face classes in the spring of 2020. One of the difficulties experienced by universities that abruptly conducted non-face-to-face education was management of the quality of education. Therefore, this study compared and analyzed how the existing indicators used to measure the quality of education in a non-face-to-face education environment changed. The results of the survey on the degree of adaptation and satisfaction of the lecture held at Handong University in the spring of 2020 were compared and analyzed with the previous data of the same lecturer. Overall, both class adaptation and satisfaction scores were found to be similar or slightly higher than before. Compared to lectures conducted by uploading recorded lectures, lectures conducted in real time had higher scores on all satisfaction survey questions. There was no significant change in satisfaction depending on the number of participants and the teacher's previous online lecture experience.

The purpose of this study is to identify factors in selecting the elective ICT utilization lecture and to find positive and negative elements of the lecture through conducting topic modeling analysis of text mining of the narrative lecture evaluation. In order to do so, from pre-processing of data, keyword frequency analysis to wordcloud visualization and topic modeling analysis have been conducted from 'reasons of selecting the lecture,' 'improvements to be made on the lecture,' and 'what I liked about the lecture' categories regarding the ICT utilization lecture which was opened in the second semester of 2019 at M University. The analysis results show that students mostly registered for the ICT utilization lecture at M University to obtain a certificate and the fact being certified and taking the lecture can be done simultaneously is a positive element of taking the lecture. On the other hand, negative element included inconvenience of the classroom setting environment.

In the downstream of the Nakdong River, water facilities - Hapcheon Changyoeng weir, Changyeong Haman weir, Nakdong River left and right sides Barrages - have been built and operated. Each facility is located at a distance. Integrated and linked operation of these water facilities is important for the management of national water resources and efficiency, effectiveness of facilities operations. For the reason, we have planned and made the system that can operate the individual facilities organically, using ICT technologies. At K-water Nakdong River Integrated Operation Water Center near Nakdong River Estuary Barrages in Busan, We implemented the water resource integrated operation system through the ICT systems convergence. For the system we expect significant effects - efficient water management, operating cost saving, etc.

This study was conducted to survey the learners' satisfaction with the online head and neck anatomy class and obtain basic data for the purpose of possibly making continuing online class educationally more effective. A Google Forms survey was conducted with dental hygiene students, and 120 copies of the questionnaire were used as data for the final analysis. The study surveyed when they take on online classes and the types of online classes and had the respondents subjectively evaluate their own understanding of the classes and their academic achievements through them. The biggest influence on learning immersion was academic achievement and the biggest influence on the satisfaction with online class was the students' understanding of the class. It is hoped that the research results will shed light on the directions for designing new curriculums in anatomy in this era of a pandemic.

유입되는 담수의 영향을 크게 받는 한 하구 (미국 버지니아주의 요크강)의 크기별 식물성플랑크통의 역학에 대한 수리역학적 조절에 대한 조사를 위해 플랑크톤 생태계모델이 계발되었다. 모델은 요크강 하류의 상부층에서의 탄소 및 영양염의 분포를 나타내는 12개의 구성체 변수로 이루어져 있다. 빛, 온도, 바람, 해류 그리고 조수와 같이 이송과 혼합을 일으키는 물리적 변수들로 포함하고 있다. 모델은 포트란으로 계발되었고 Runge- Kutta technique을 이용해 미분방정식을 풀었다. 모델분석 결과, 크기가 큰 마이크로 식물성플랑크톤의 수화는 수체내의 생산보다는 이송이나 확산 때문에 나타나는 것임을 알 수 있었다.

This paper suggests efficient learning improvement method of computer use instruction based on flipped learning. Traditional computer use classes were difficult to practice and collaborative with sufficient lectures. However, we used KOCW (Korea Open Courseware) as a footsteps in the class using the flipped learning method and learned in advance before entering the classroom. In the classroom, we conducted collaborative hands on class based on mutual discussion. After the instruction, we measured learning motivation and satisfaction by gender, grade, and major using the motivation test tool. The results showed that degree of attention awareness, perception of class relevance and perception of learning satisfaction were analyzed as 'very satisfied' and 'satisfied' more than 90%.

Previously, there were no studies that were not aware of the importance of video, were interested in the educational value of Flipped Learning, and there were many wrong experiments because they did not understand Flipped Learning. Therefore, an accurate understanding of Flipped Learning is needed. This study proposed the caution of video learning of Flipped Learning and presented the papers and grounds to support to examine the educational value of Flipped Learning. A video of the lecture should be produced with a core content of 10 to 15 minutes, and found that the educational value of Flipped Learning lies in self-directed learning, cooperative learning, habruta, overcoming the oblivion curve and metacognition. It is hoped that this study will provide good guidance and direction of education for teachers who have difficulty Flipped Learning.

The purpose of this study is to propose a strategy to educate the core contents of various major fields in practical and convergent ways in universities in order to prepare for the 4th industrial revolution era. First, convergence field is established in the university curriculum in addition to the existing major and the liberal arts field. Second, convergence courses are created in connection with job ability, which are major curriculum but only for students in other departments. Third, convergence courses are organized in the form of module curriculum, which is a small-sized and independent curriculum consisting of 4 courses. D University, one of the local private universities in Korea, has provided such convergence module education since 2016, and satisfactory results have been obtained in the course enrollment rate and the course evaluation, etc. By combining these convergence modules in various ways, it is possible to easily create customized majors required and designed by local companies at low cost.
