Cellular phones have been popularized and some of them even have access to the Internet. But the utilization of mobile phones has not been for education but only focused on particular services due to the text-based low capacity. This thesis proposes a multimedia education system using cell phones with SMIL. We can decrease the size of the parser and refute the resources of CPU by designing SMIL tag only, which is needed for multimedia education. In addition, the macro method for producing information for lectures will make possible decreased transmission quantity of multimedia contents and increased transmission efficiency. This will lead to overcoming the matter of insufficient CPU and memory, which is common to most mobile phone terminals.

Christian education for the world after COVID-19 needs to use rapid changes in the surrounding situation as an opportunity to overcome a new crisis so that the church can achieve its educational mission. If the biggest dilemma in the post-Corona era is that there is no authoritative educational prescription anywhere, the most reasonable option for church education in this situation is to emphasize and cultivate learners' ability to flexibly cope with rules that are completely different than before COVID-19. As a natural result of the crisis, Christian education needs to be more interested in the trend of social change in the pandemic era(glocalization, digital transformation, economic inequality, educational environment change, church crisis) and actively reflect its contents in education. In addition, while operating a mobile(or online) church school that combines offline and online, there is an urgent need for an innovative transition to a core church school where certain church schools and churches cooperate with each other, a church school that guarantees a safe learning space, and an ecological church school that is interested in education dealing with climate change and ecology.

본 논문은 모바일 기기인 스마트폰이 교육환경을 바꾸고 있는 현실에 착안하여 대학 수업에 필요한 몇 가지 방안을 제시하였다. 모바일 기기인 스마트폰은 휴대성과 신속성이 강하기 때문에 컴퓨터와 노트북이 갖는 불편한 점을 보완할 수 있다. 그렇기에 스마트폰은 교육적 활용도가 높다. 먼저 교수는 수업 전에 학생들이 카카오톡을 가입해서 활동할 수 있게 한다. 예컨대 단체 카톡방, 조별 카톡방을 운영해서 공지사항을 올리고 학생들과 소통해야 한다. 때로는 개별 카톡방을 운용하면서 학생들에게 필요한 정보와 상담을 제공할 수 있어야 한다. 또한 학생들은 주어진 과제를 수행하기 위해서 조별 카톡방을 적극 활용해야 한다. 이는 학생들이 조별 카톡방을 통해 과제를 수행하는 과정에서 발생하는 시간과 공간의 제약을 극복하게 해주기 때문이다.

In this paper, we tried to enable a mobile device as a resource to access to mobile grid networks. By advanced Internet techniques, the use of mobile devices has been rapidly increased. Some researches in mobile grid computing tried to combine grid computing with mobile devices. However, according to intrinsic properties of mobile environments, mobile devices have many considerations, such as mobility management, disconnected operation, device heterogeneity, service discovery, resource sharing, security, and so on. To solve these problems, there are two trends for mobile grid computing: a proxy-based mobile grid architecture and an agent-based mobile grid architecture. We focus on a proxy-based mobile grid architecture with IP-paging, which can easily manage idle mobile devices and grid resource status information. Also, we use SIP(Session Initiation Protocol)to support mobility management, mobile grid services. We manage variation of mobile device state and power by paging cache. Finally, using the candidate set and the reservation set of resources, we perform task migration. The performance evaluation by simulation, shows improvement of efficiency and stability during execution.

The biggest challenge immigrants face is language. We realized that Korean education contents suited for it are lacking more than we thought. To help with the above problems, we decided to make a mobile game for Korean conversation education. The proposed game is based on the online course of Sejonghakdang and is composed of life conversation which can be used immediately in real. We selected female marriage immigrants from China who have a large number of foreign residents and need a lot of Korean education but have a relatively low chance of being contacted. In the case of female marriage immigrants, communication was possible, but it was characterized that the composition of sentences was not smooth. Considering these features, we chose the game method that can match the problem in the unit of the word.

According to KISA, many people play smartphone games. stress relieving, time is the reason to beat. Attempts to combine mobile games and education in the Korean game market are continuing. Studies have shown that using commercial games for education can be effective. Also, researches for activation educational games are increasing. Creating educational games requires a lot of time and money. Due to the nature of mobile games, the service is often terminated without updating. If you are able to acquire a naturally educational part while playing mobile games, you will see the effect of one pair of fun and education, both at once. We analyzed the education factors of the game with 'Real Farm' which is a simulation farm game. We focused on analyzing information acquisition and utilization part through indirect experience which is characteristic of simulation and examined educational factors based on design elements of educational game. This can signal the positive aspects of the game and the educational content of existing games. If you use smartphones as a pedagogy, you can expect a positive perception of games and an increase in the average life expectancy of mobile games.

The purpose of this paper is to implement the educational application related to the Plant's Life Cycle Unit in 4th Grade Science Textbook, based on the National Curriculum. This should lead to teachers incorporating them into classes and for students to get practical help when they are studying about plants. Through this application, teachers will be able to experience the so-called Blended Learning while using both off-line and mobile teaching methods. It will also be possible for students to review what they learn during the classes and do their projects regardless of time and place. This type of learning is expected to motivate learners and enhance the learning experience by stimulating the students' interest.

In recent years, wireless networks have been widely deployed and the use of mobile devices has been popularized. As a result, mobile devices are increasingly considered as a resource of the Grid However, there are some problems such as unstable wireless communication and disconnection of mobile devices caused by movement in Mobile Grid Therefore, a scheduling method allocating jobs to the mobile devices should progressively deal with this problem The existing scheduling methods in Mobile Grid have mainly focused on the connection time of mobile devices. The connection time of mobile devices shows typically a regular pattern according to a user's living environments such as vacation/class in school, weekday/weekend in work, and so on. In this paper, we analyze statistics information for the utilization patterns of mobile devices and propose global and local scheduling methods for Mobile Grid, based on the analyzed utilization patterns.

With the development of SNS, many different areas including education are utilizing SNS in various ways. And there are more and more learners and teachers who intend to use it for learning. Lately, however, the students using SNS environment hardly consider the issues regarding copyright, so this is raising even legal issues, too. Therefore, this study has examined the degree of recognition of undergraduates on copyright and extracted the general cases of copyright which undergraduates may face in the actual class or everyday life. The cases extracted are expressed in the rules of "If ~ Then", stored in the knowledge base of rules in the rule-based system, and realized as the mobile web. And regarding the copyright-related problems inputted by the students, similar rules are drawn from the knowledge base of rules so that they can solve copyright-related problems anytime, anywhere with the mobile web in a self-directed way.
