모바일 기기의 사용자 만족도를 평가하기 위해 interface 부분만 아니라, 물리적 외형(design)에 대한 평가가 중요하게 되었다. 특히, 휴대폰의 물리적(physical) 부분을 평가하는 사용자의 감성적, 선호도를 중심으로 평가 되었다. Design 에 대한 Usability 측면을 고려하여, 감성적 선호도를 넘어서서 사용자의 사용 scene을 고려한 Physical User Experience 에 대한 영역정의가 필요로 한다. 또한 평가시 활용된 방법에 대해서도 정의가 필요하다. 따라서 이러한 특성에 의해, 모바일 기기의 4Physical User Experience를 평가하기 위한 사용자의 모바일 기기의 영역은 무엇이며, 평가 수행시 결과의 효용성을 높이기 위한 방법이 무엇인지 본 논문을 통해 정의하고자 한다.

A lot of existence e-learning are connected SCORM and LMS. And u-learning was researching as one of the new trend. But there are few research paper to connect the existing SCORM and LMS. In this paper, we proposed u-learning framework with connect the SCORM and LMS. And we used the mobile equipment transform module and learning object reconstruction module to apply each different characteristics of mobile equipment. Especially, information of the mobile equipment was stored and managed using the meta-data of the equipment.

As respecting one's privacy becomes an important issue in mobile device data analysis, on-device analysis is getting attention, in which the data analysis is conducted inside a mobile device without sending data from the device to outside. One possible application of the on-device analysis is gender prediction using text data in mobile devices, such as text messages, search keyword, website bookmarks, and contact, which are highly private, and the limited computing power of mobile devices can be addressed by utilizing the word comparison method, where words are selected beforehand and delivered to a mobile device of a user to determine the user's gender by matching mobile text data and the selected words. Moreover, it is known that performing prediction after filtering instances using definite evidences increases accuracy and reduces computational complexity. In this regard, we propose a two-phase approach to on-device gender prediction, where both discriminability and popularity of a word are sequentially considered. The proposed method performs predictions using a few highly discriminative words for all instances and popular words for unclassified instances from the previous prediction. From the experiments conducted on real-world dataset, the proposed method outperformed the compared methods.

2009년 아이폰 출시로 시작된 국내 스마트폰은 트워터, 페이스북과 같은 SNS와 더불어 급속하게 보급되어 1,000만 사용자 시대를 맞이하고 있으며, 스마트폰의 경험을 그대로 활용할 수 있는 태블릿의 출연으로 인해 개인적인 활용에서 업무의 효율성과 형태에 대한 변화도 가져오고 있다. 모바일 오피스, 스마트워크 등 정부와 기업의 업무 효율화에 대한 관심과 녹색 성장 정책에 따라 스마트 기기의 확산과 활용은 더 급물살을 탈 것으로 보인다. 스마트 기기는 PC와 많은 부분이 닮아 있지만 이동성과 개인화된 기기라는 점에서 개인정보 유출이나 금전적인 피해에 노출되기 쉬워 이에 대한 대책 수립이 필요하다. 본 고에서는 스마트 기기로 인한 패러다임의 변화와 보안 위협과 보안 위협의 대표적인 모바일 악성코드의 트렌드를 알아보고자 한다.

With the diversification of mobile devices, the development of web technologies, and the popularization of the cloud, an internet-centric web OS that is not dependent on devices has become necessary. Chromebooks are mobile devices in the form of convertible laptops featuring a web OS developed by Google. These Web OS mobile devices have advantages of multi-user characteristics of the same device and storage and sharing of data through internet and cloud, but it is easy to collect and analyze evidence from the forensic point of view because of excellent security and easy destruction of evidence not. In this paper, we propose an evidence collection procedure and an analysis method considering the cloud environment by dividing the Chromebook, which is a web OS mobile device popularized in the future, into user and administrator modes.

In this study, IT education contents have been developed based on the u-Learning approach for people with hearing impairment, focusing on allowing the user to learn from anywhere and anytime. Specifically, this study applies HTML5 to implementing IT education contents(JSP, Oracle) for the deaf because HTML5 enables the learner to access the contents through both web and mobile device on various platforms including android, Mac OS, and PC etc. The results of this study are as follows: First, the online computer courses are mostly supposed to be compatible with diverse types of mobile devices. However, some of the contents could not be run on applications residing in web and mobile devices because the contents tend to be developed using FLASH. HTML5 is the effective way to overcome the compatibility problem. Second, FLASH and HTML5 contents authoring tools have been compared in terms of their strong and weak points by applying the developed contents to those tools. The study also suggests that the future work would be needed in order to implement wide variety of event functions with HTML5. Lastly, design strategies enabling access through web and mobile devices have been analyzed in accordance with u-Learning design guidelines for the deaf and mobile application accessibility guidelines. However, in the latter case, the future work regarding design guidelines needs to be conducted to improve the educational accessibility depending on the level of impairment.
