현재 스마트폰(Smart phone) 및 테블릿 PC의 시장이 급속하게 성장함에 따라 현실 생활에 많은 변화가 일어나고 있으며 다양한 제품을 생산하는 생산 현장에서도 새로운 유형의 스마트모니터링 시스템의 도입이 가속화 되고 있다. 뿐만 아니라 테블릿 PC 시장의 급성장으로 인하여 기존의 사무실에서 관리하던 원격 모니터링 시스템이 급속도로 모바일 기능이 탑제된 스마트모니터링 시스템으로 발전해 나가고 있다. 본 논문에서는 갤럭시탭을 기반으로 다양한 품목을 생산하는 제조현장의 생산검사항목을 대상으로 하여 스마트디바이스(갤럭시탭)를 통하여 스마트디바이스에서 획득한 이미지(image) 정보과 텍스트(text) 정보를 원적지로 전송할 수 있는 기능과 또 다른 원격지에 모니터링 할 수 있는 스마트모니터링 시스템을 개발하여 모바일 스마트기기의 활용도를 높이고 보다 유연성이 있는 스마트모니터링 시스템을 제시하고자 한다.

최근 삼성전자와 애플에서 갤럭시폰, 갤럭시탭 등의 갤럭시 제품군과 아이폰, 아이패드 등 애플 제품군을 두고 세계 곳곳에서 치열한 특허전쟁이 벌어지고 있다. 여태까지의 소송에서는 애플이 적극적으로 삼성을 공격하는 입장이었는데 최근에는 삼성에서 애플에 적극적인 공세를 취하는 모습을 보이고 있다. 이러한 과정에서 삼성이 네덜란드의 헤이그 법원에서 삼성의 표준특허를 이유로 애플의 아이폰 판매금지가처분 신청을 신청한 사안에서, 헤이그 법원은 애플이 주장한 F/RAND 논리를 받아들여 삼성의 판매금지가처분 신청을 기각하였다. 그렇다면, 최근 특허업계에서 이슈가 되고 있는 표준특허란 무엇이고, F/RAND란 무엇일까? 먼저 표준특허에 대해서 간략히 살펴보고 삼성과 애플사례를 토대로 F/RAND에 대해서 살펴보도록 하겠다.

본 작품은 학생들의 캡스톤디자인 작품이다. 본 작품은 지금까지 내려온 전래동화에 나와 엄마, 아빠가 등장할 수 있는 있도록 동화속의 캐릭터 대신 독서자의 얼굴을 교체한 작품이다. 즉, 아이와 부모가 전자기기(갤럭시탭 등)에 등록된 사진을 동화속 주인공 대신 삽입하면 동화를 읽으면서 가족간 서로의 역할을 수행하는 작품으로 아이가 동화속에 이입될 수 있고, 집중할 수 있도록 꾸민 작품이다. 본 작품의 개발은 플래시 기술을 활용하지만, 앱 형태로 제작되어 동화를 좋아하는 아이와 부모가 쉽게 접근하도록 개발되었다.

In recently years, repackaged malwares are becoming increased rapidly in Android smartphones. The repackaging is a technique to disassemble an app in a market, modify its source code, and then re-assemble the code, so that it is commonly used to make malwares by inserting malicious code in an app. However, it is impossible to collect all the apps in many android markets including too many apps. To solve the problem, we propose RePAD (RePackaged App Detector) scheme that is composed of a client and a remote server. In the smartphone-side, the client extracts the information of an app with low CPU overhead when a user installs the app. The remote server analyzes the information to decide whether the app is repackaged or not. Thus, the scheme reduces the time and cost to decide whether apps are repackaged. For the experiments, the client and server are implemented as an app on Galaxy TAB and PC respectively. We indicated that seven pairs of apps among ones collected in official and unofficial market are repackaged. Furthermore, RePAD only increases the average of CPU overhead of 1.9% and the maximum memory usage of 3.5 MB in Galaxy TAB.

Many people are now enjoying mobile games using various smartphone platforms. However, we have to develop games separately for each smart device platforms so far. Cocos2d-x, a game development framework is released to solve this problem. As a multiplatform version of the existing Cocos2d, Cocos2d-x can make one source code run on various platforms. It is an open software that is able to be used by everyone, and when using it, mobile games can be developed easily based on C++ and OpenGL. In this paper, we implemented a PC laboratory decorating game application, named ILove501, using Cocos2d-x. The 501 is a room number of our PC lab. ILove501 includes an educational feature of solving quizzes in order to highlight positive effects of game. For implementation of a multiplatform game, ILove501 was developed in Windows and iOS environment at the same time, and we verified the results of the execution by porting on a variety of devices such as Android, iPhone, iPad and Galaxy Tab.

Recently, the concept of PES(Personal Environment Service) is being widely discussed on various standardization organizations such as ITU-R, ETSI, 3GPP, TTA and etc. The purpose of PES is to introduce the services which can dynamically, automatically and intelligently reconfigures the electronic, electrical, and mechanical equipment surrounding the user according to the user preferences included in a user's profile by using a smartphone embedding WPAN radio technologies such as bluetooth and WiFi. This research introduces an Android Platform-based PES system which consists of a PES app, PES devices and a PES server. A smartphone platform is Android 2.2(Froyo) version and 4 simulated PES devices were implemented by using Galaxy Tab. It has shown that the PES would be a killer application of M2M(Machine-to-Machine) or D2D(Device-to-Device) in the future and it would need to study how to update a user's profile based on analyzing user's behaviour for enhancing the PES user's satisfaction.

Many e-book readers have become available as e-books are in popular use these days. We first developed the evaluation criteria and elements for testing the usability of e-book readers and then examined the usability of three e-book readers. The usability testing was conducted using three e-book readers that were most popular with 15 participants that consisted of middle school students, university students, and office workers. The study found that iPad showed the best usability. In case of Amazon Kindle, participants indicated that the lack of the touch function imposed a great deal of negative impact on the usability of the interface. Also, the hardware- and software-oriented usability provided by an e-book reader was considered to be a very important element for the users, and the portability in connection with the hardware-oriented aspect of an e-book reader was shown to be of great effect to the overall usability of an e-book reader.

Recently, the smart phone, a carrying along terminal connection technology such as Galaxytap/iPad etc. evolves, and supply is increasing rapidly, is included for smart phone because various sensor technologies are developed and service application that is acted in terminal with this is accompanied and grow. Continuously 4 generation to 3 Gs, Wibro Wireless network technology of communications a LTE technology from that is constructed, environment for Ubiquitous realization is being constructed fast. Therefore, in this paper it can inquire state of electronic, furniture devices through apartment complex web server and gear that control groove network at smart phone, and control, and confirms home state prevention of crimes state, and video inquiry of position that CCTV is placed in apartment complex was available. And it proposed integrated smart apartment with parking system and medical system using RFID system in ubiquitous environment.
