본 논문에서는 모바일 애플리케이션의 사용자 잔존율 향상을 위한 방안으로써 내러티브 모션을 기반한 온보딩을 제안한다. 모바일 기술의 발전과 새로운 미디어에 대응하는 디지털콘텐츠 애플리케이션에 대한 관심이 증가하고 있는 가운데 사용자에게 외면받아 사라지는 애플리케이션의 증가가 가속화되고 있다. 이에 따라 사용자의 긍정적 경험 제공을 위한 사용성 향상 연구는 빠르게 진행되고 있으나 애플리케이션의 첫인상과 지속적인 사용을 결정하는 온보딩에 대한 연구는 아직 미비하다. 경쟁이 가속화 될수록 보다 효과적인 사용자경험을 제공하기 위한 온보딩 개발의 중요성은 증대되어 갈 것이며, 결국 온보딩 개발의 핵심 쟁점은 사용자의 긍정적인 인지적 반응과 태도를 이끌어낼 수 있는 요인인 모션이 될 것으로 예측된다. 따라서 본 논문에서는 모바일 온보드에서 제공되는 애플리케이션의 다양한 특성을 표현하기 위한 요인으로서 내러티브 모션을 제시하고 애플리케이션 지속사용 여부에 영향을 미치는 요인을 도출하여 둘의 상관관계를 실증적으로 분석함으로써 앞으로 등장할 새로운 서비스 및 플랫폼의 애플리케이션 개발 필요한 모션요소를 도출하고자 한다.

VoIP기술은 기존의 음성서비스를 인터넷을 통하여 제공하고자 하는 기술로 기본적인 인터넷 전화 서비스에서부터 화상회의, 원격교육, 인터넷 콜 센터 등 최근 다양한 응용분야로 그 기술이 확대되어 가고 있다. 본 논문에서는 이러한 VoIP 기술의 적용을 위해 현재MGCP를 사용하고 있는 Virata 평가보드를 SIP UA(User Agent)로 사용하여 간단한 인터넷 전화를 구현하는데 필요한 SIP 스택분석 및 효과적인 활용방안에 관해 논하였다. 이를 위해 VOVIDA사의 VOCAL(Vovida Open Communication Application Library) 오픈 프로젝트 중 SIP UA 부분을 분석하였으며, 이를 기반으로 분석된 소스를 평가보드에 효과적으로 탑재하고 활용하는 방안을 제안하였다

In recently years, the research and application for sensor has increased in each field. In this paper, the system which can perceive and detect using 3-axis accelerometer sensor and serial communication is proposed. Also, the user has GUI environment for monitor in real-time. In order to reduce unstable data and error defect of electronic rechargeable liquid tilt sensor used digital 3-axis accelerometer sensor which has AD convertor. Therefore, this system provide exact data and a problem of objects for user more easier.

Weighting strategy is one of the necessary control strategies in automated reasoning to solve problecs within allowable time and computer memory. But, the strategy still consumes too much time since it depends soly on the user's experience and needs much of the user's manual work at each stage. This research suggests a tool which automates the weighting system to generate the weighting thesaurus and merges it to the mechanical theorem prover.

현대에 많은 사람들이 스마트폰, mp3 player와 같은 휴대기기에 많은 음원 파일을 넣어 음악을 듣는다. 그 음악 중에는 잘 듣지 않는 것도 다수 존재하지만 사용자는 그런 파일을 즉시 지우지 않을뿐더러 자기 자신조차 어떤 음악을 즐겨듣는지 아닌지 모두 파악하지 못한다. 본 논문에서는 사용자들이 음악 재생기를 조작할 때 발생하는 행동 패턴을 기반으로 음악의 선호도를 산출하고, 이를 이용하여 음악 선호도 순위 정보를 사용자에게 제공하여 음악 관리를 편하게 할 수 있도록 해주는 시스템을 제안한다.

In this paper, we propose to study on the application of the alarm algorithm to the platform of portable radiation detection device based on Coretex-A9 to ensure the safety of user. The analog board transforms sensor's signal and the platform based on Cortex-A9 outputs the results. The radiation detection's alarm is realized to LED and Buzzer to ensure safety of user.

The amount of personal information has increased dramatically due to the prevalent use of smartphones and the rapid growth of social networking services. Under these circumstances, there has been a lot of efforts to obtain new information based on the overflowing personal data. The conventional character analysis method, which heavily relies on personal surveys, had some limitations in that it was difficult for psychologist to have a complete access to the surveyed results. When it comes to celebrities, however, it is relatively easy to access to their information through various media. Therefore there has been various researches that examined celebrities' personalities. On the contrary, not many studies have focused on analyzing the characteristics of the general public whose information is not so accessible. In this research, we suggest a method to analyze ordinary people's characteristics based on information available via their social networking services. This research focuses on developing a Facebook-native application, which examines the user's character type based on the posts shared in the user's Facebook page.

In recent years, the development of ubiquitous computing environment, according to the time, place, regardless of the environment changes dynamically based on providing a service. In particular, ubiquitous computing environment, education support services in the fields of education according to the principal of each member is required to provide personalized information. Therefore, this paper describes the education support system which provide adaptive information to member of education. The structure of the proposed system consists of mobile agents multi-agent system platform, JADE (Java Agent DEvelopment framework) is based. Also, we describes the design of agents for application services and the interaction model. In this paper, the performance of proposed system to verify availability, classroom teachers, students and parents and administrators as a service application based on the user's role to provide appropriate information system was implemented. Finally, we shows the result of user interface GUIs according to adaptive education services.

By developing the IoT(Internet of Things) technology, devices for smart home environment have rapidly increased. With respect to mobiles, these applications are used to control and manage the various smart devices effectively. However, the existing mechanisms only provide simple information, and hence a difficulty to search or control the smart devices persists, since there is no meaningful relationship between them. In this research, we suggest an interface which visualizes the device's data and controls them effectively, based on the user's device using pattern. As a solution for this problem, we classify the user pattern based on a timeline for the associated circumstance, and visualize the device's data to make a group or to control individually in an easier approach. Also, all meaningful information could be confirmed by summarizing all the data of smart devices.
