Rapidly developing mobile internet technology and extensive service of smart phones have led to growing use of mobile applications. It is natural that software developers and IT-related students develop a variety of applications that can be used for everyday life. The present paper reports a case of developing such an application that was developed in a capstone design course of Department of Computer Science at Namseoul University. This so-called 'Application for Prevention of Loss of One's Belongings' was designed to let students learn a set of tools based on Android operation system. This app can prevent smart phone users from losing their belongings using an alarm. The educational effect from the process of developing this application is also discussed.

Education using smart mobile devices has become part of current children's art education activities. Today's release of pen-equipped mobile devices and smart tablet PC's allows users to painting and coloring with digital devices. Today, art content for children is downloaded and can be educated at any time as an application. However, coloring games that give children the effect of art education are extremely rare, and the content elements in the games are similar to all games and lack the ability to express themselves. The study recognizes the importance of developing coloring game content for children's art education that can help children's coloring activities and improve creativity and imagination, and focuses on the direction and elements of developing children's coloring game content using smart mobile devices that fit digital coloring functions.

Presidential archives have higher historical value than other public documentaries. It is a reliable documentary reflecting aspects of contemporary life and has high value and availability in the education field. This study suggests how to intensify the role as an intelligence service of presidential archives and how to develop the utilized-Presidential Archives mobile education contents in G-learning environments to lead the positive awareness on Presidential archives. After suggesting the 7 levels methods about the development of mobile education contents using presidential archives in G-learning environments, This study shows the case of the applied educational contents on the subject of $5^{th}$ grade at the elementary school. 7 levels methods include pre-planning, pre-design, selecting presidential records, presidential records story-telling, making the storyboard, implementing a game, sharing and assess.

As the 2015 revised curriculum is being implemented from 2018, efforts are being made to cultivate scientific literacy among students in the field of science. Scientific experiments help students to develop their interest in Science and their scientific attitudes. Learning through experimentation rather than learning scientific facts increases learners' understanding, and can be remembered longer. Therefore, experiments in Science subject are very important. However, in middle schools, scientific experiments are not performed due to the lack of time, budget and experimental material. In this research, we analyze middle school science textbooks, conduct questionnaires for students of science pre-service teachers, select the most important science experiments, and develop a mobile App to simulate and experience scientific experiments with the App. The proposed App is developed in a game format using quest-based learning methods to gain learning enhancement. It is also made using Unity. In this paper, after developing the app, we propose the direction of STEAM contents development through analyzing the difference from existing apps and the feedback from users.

컴퓨터 프로그래밍 교육은 컴퓨터과학 분야의 관련 전공과목을 공부하기 위하여 매우 중요할 뿐만 아니라, 학생들의 취업을 위한 기술 교육에서도 매우 중요하다. 이 논문에서는 학생들의 교육 및 취업에 적합한 교육용 및 상용 프로그래밍 언어, 도구에 대한 타당성을 분석하여 프로그래밍 교육에 적합한 프로그래밍 언어/도구를 선택하고, 이에 대한 교육 과정을 개발하여 프로그래밍 현장 교육에 적용하고 분석한다. 특히, 최근의 기술 추세와 산업계에 필요한 임베디드/모바일/웹/3D 프로그래밍 분야에 널리 사용되고 있는 프로그래밍 분야에서 텍스트 기반 언어(예: JAVA)와 시각 프로그래밍 언어/환경(예: LabVIEW)에 대한 유용성을 비교하여 분석한다.

The mobile application Open Market of the Apple company's App-store is serviced by the domestic communication company. The domestic developer concentrates on the development and trading ont the market of the application. But App-store's I-pod is different from the Korean mobile. The developer can't use the mobile test because there are a lot of mobile in korea. To solve this, we propose that developers can more easily use the mobile test with mobile simulators on the web. This system does the least amount of tests with many mobile terminals and is the verified trading application.

프로그래밍 모바일 앱은 장소에의 제약성 해소와 장비의 경량화가 가능하다. 프로그래밍 실습을 위한 환경으로 PC나 서버 연결 온라인 환경 등이 주로 사용되나 모바일 앱은 거의 사용되지 않는다. 이 연구에서는 모바일 앱을 활용하여 프로그래밍할 수 있는 환경을 설계하고 구현한다. 프로그래밍 언어로는 LISP의 파생어인 Scheme을 사용하였다. Scheme 언어는 다중 패러다임 언어로서 프로그래밍 교육에서 다양한 관점으로 문제 해결 방식을 제공할 수 있다. 이를 통해 Scheme 언어에 대한 인터프리터를 서버리스 프로그래밍 앱으로 설계하고 구현하는 과정을 기술한다. 구현 결과에 대한 인터프리터 처리 성능 실험으로 재귀 함수로 피보나치 수열을 계산하였을 때 PC 수행 시간에 대한 모바일 버전 수행 시간 백분율 기하 평균은 0.96으로 모바일 환경에서도 일반 컴퓨터 환경에 버금가는 처리 성능을 얻음을 확인하였다.

The aim of this study is to present the handover procedures and the performance comparisons of layered mobility management schemes for wireless mobile Internet. To investigate efficient mobility management schemes providing seamless information services in a mobile environment, this paper provided the detailed discussions of existing network layered mobility management scheme, including Mobile IPv4, Mobile IPv6, and new transport layer mobility management scheme, stream control transmission protocol (SCTP) based mobility architecture (SMA). Network simulator-2 (ns-2) was used to compare the performance between Mobile IPv6 and SMA in the wireless mobile Internet environment. Simulation results show that for typical network configuration and parameters, SMA has a lower handover latency, lower packet loss rate, and higher throughput than Mobile IPv6.
