Due to Covid-19, the un-contact culture has affected society as a whole, and the methods of education conducted offline has been greatly affected. In the private education of preparing for university entrance, the public official examinations and certification acquisition, the method of online education has been shown to have positive effects. While private class and school class which have offered in off-line to cope with rapid changes caused various problems such as decline in quality for education. Due to the characteristic of design class, practical training is important. As interactive feedback between students and educators is more important than one-way of delivering knowledge while class is conducted in online, educators have a challenge when they prepare for class. This study handles the methods of online education for the purpose of practical education methods in university nowadays, Especially, the non-face-to-face education methods for game animation production. Based on this study, I propose an effective educational method with non-face-to-face class that allows students to be satisfied and increases their knowledge, beyond face-to-face class.

Purpose This study analyzed the topic of game review contents and how the characteristics of game reviews affect the reviews helpfulness. In addition, this study explore the content of game reviews according to the game's sales strategy such as early access strategy and releasing without early access. Design/methodology/approach We collected a list of 3,572 action genre games released in 2020. 58,336 online reviews were collected by random sampling 50 reviews in each games, and topic modeling was performed on those reviews. We dynamized the results of topic modeling and analyzed the effect on review helpfulness with multiple regression analysis. Findings The results of analysis indicate that the longer the review is or the shorter the time it is written, the more helpful the review is. In addition the topic with positive and negative review has a significant effect on the review helpfulness. As a result of exploratory analysis, games from early access had relatively fewer reviews of story-related topics than games that were released without early access. These findings can present direct guidelines for collecting specific opinions from customers in the game industry when releasing games.

This study is an exploratory study to examine the relation between parents and children's smartphone usage time. The data from the 11th Korea Media Panel Survey conducted by the Korea Information Society Development Institute was used for empirical analysis. The findings revealed that parents' smartphone usage time and children's smartphone usage time are positively correlated, indicating that their smartphone use patterns share similarities as members of a family system. This study lays the foundation for future work to explain individual media use through family and media use environment.

주어진 경계선에 대해 비누막이 생성하는 표면 모델링 및 시간에 따른 변형 시뮬레이션은 컴퓨터 그래픽스 응용 프로그램의 한 분야이다. 이 문제에 대한 이전의 연구들은 주로 기하적인 방법들을 이용하였기 때문에 물리적으로 정확한 변형을 다루지 못하였다. 본 연구에서는 정확한 기하를 바탕으로 물리기반 변형을 다루기 위해 이산미분기하학으로부터 비누막의 동적인 모델을 제안한다. 우선, 비누 성분의 물리적인 특성들을 고려한 에너지 모델을 정의하고, 이를 이산 영역에서 나타내기 위해 이산미분기하 및 이산화 기법들을 이용한다. 제안하는 모델은 평형 상태에서의 비누막 형상뿐만 아니라 외력에 대한 표면의 변형까지 정확하게 나타내며, 실시간 시뮬레이션이 가능하여 게임, 애니메이션 목적으로 활용될 수 있다.

최근 각광 받고 있는 멀티 터치 인터랙션 시스템에서 기존의 디스플레이 방식인 벽면 디스플레이 방식의 네모난 형태의 디스플레이 방식이 아닌 볼록형(Convex) 불규칙 디스플레이 방식으로 산 모양의 디오라마 형태의 디스플레이에서 멀티 터치 인터랙션이 가능한 시스템을 제안한다. 먼저 볼록형 불규칙 표면의 산 디오라마를 제작을 하고 후면 투영 방식으로 프로젝터 영상을 산 디오라마 표면을 대상으로 디스플레이 하고 영상 분석 모듈을 통하여 터치 인터랙션 좌표 정보를 분석한다. 분석된 터치 인터랙션 좌표는 3D 좌표로 변환하고 디스플레이 모듈에 보내면 디스플레이 모듈에서는 인터랙션 메타포로 분석하고 결과를 콘텐츠에 실행시킴으로써 볼록형 불규칙 표면의 산 디오라마에서 멀티 터치 인터랙션에 따른 결과를 사용자가 체감 할 수 있도록 하였다. 본 시스템은 향후 다양한 디오라마 형태로 제작하여 목적에 맞는 전시 시스템으로의 디바이스나 체감형 아케이드 게임 디바이스로 활용이 가능할 것이다.

The development of broadband multimedia content, a deaf sign language sign language is being used in education. Most of the content used in sign language training for Hangul word representation of sign language is sign language videos for the show. For the first time to learn sign language, sign language users are unfamiliar with the sign language characteristics difficult to understand, difficult to express the sign is displayed. In this paper, online, learning sign language to express the sign with reference to the attributes, Semantic Logic applying the sign language of multimedia content model for video-based platform is designed to study.

In order to improve students' interest, class participation and class comprehension in engineering theory classes, a class applying review games as Jinjinga, Bingo, etc. were designed and developed. Through applying them to three engineering theory subjects, the specific effects of the strategy on students' understanding, interest, participation, and academic achievement were analyzed and the usefulness of each review game strategy was analyzed. Analyzing class data over the past 11 years, there was a clear correlation between performance of the students in the review game and their actual grades, which was found to be greater than the negative effect of absence rate on the test performance or grades. This study also researched students' perceptions compared to other general subjects not applying the review games. The results of a survey of the students who took the review game class showed the usual amount of usual studying hours increased, the burden of examination or the amount of studying hours for preparing the exam was reduced, and the class interest and achievement significantly increased compared to other subjects in the same major.

Piano is one of the most beloved instruments in the world and is used a lot for children to learn music because it is simple to play. As a result, various products for children, such as toy pianos, were released. However, there is a lack of piano skills for music education, such as how to play the piano or read the score. To solve this problem, in this paper, we propose a game-style educational piano using Arduino. It is expected to capture fun and education at a low price by scoring points by displaying the score on the LCD screen and pressing the keyboard according to the timing of playing the note.
