In this paper, we propose a method which implements warning to drivers through real-time analysis of risky and unexpected driver and vehicle behavior using only a smartphone without using data from digital tachograph and vehicle internal sensors. We performed the evaluation of our system that demonstrates the effectiveness and usefulness of our method for risky and unexpected driver and vehicle behavior using three information such as vehicle speed, azimuth and GPS data which are acquired from a smartphone sensors. We confirmed the results and developed the smartphone application for validate and conducted simulation using actual driving data. This novel functionality of the smartphone application enhances drivers' situational awareness, increasing safety and effectiveness of driving.

As the smartphone market grows, the needs for its new business model are also increased. However, most previous researches on smartphone applications focused on Technology Acceptance Model(TAM) and Rogers' Diffusion of Innovation Theory so that there was lack of researches on characteristics for actual smartphone users. In this research, we divided the smartphone applications into five category functions (Call & Text/Music & Video/Information Search/Game/Social Network Service (SNS)). We analyzed characteristic differences of users who used the each application category and found that the differences were statistically significant in both demographic and smartphone usage characteristics (frequency of downloading applications, and download experience of paid applications). Additionally, the smartphone usage characteristic is closely related to the usage duration. The representative result is that the characteristics of people used Music & Video function actively were women in their 20s who downloaded applications more than three times per week, and had a download experience of paid applications. It is positive result for players in the application markets, because it means the users are willing to pay for downloading the paid applications. However, large companies already occupied most of the market share in music applications so that small and medium-sized players should develop an innovative and distinguishable business model in order to success. We believe this research result would provide significant implications for the players in planning the successful business model and developing an user-specific application product.

Due to the rapid growth of smartphone market, the security threats are also increased. One of the smartphone security threats is that w1Verified applications are distributed on the smartphone market. In the case of Andoroid market, Google have no Application Approval Process that can detect malicious android application so many malicious android applications are distributed in the Android market. To reduce this security threat, it is essential the skill to detect the malicious activities of application. In this paper, we propose the android application analysis method for malicious activity detection and we introduce the implementation of our method which can automatically analyze the android application.

In this paper, we propose a musical instrument conversion based music ensemble application for smartphone. If we try to create ensemble music using virtual instruments provided by the conventional smartphone application, we should know how to play each instrument. In addition, it is impossible to play the instrument in a natural way if the smartphone screen cannot show the entire part of the instrument. To solve this problem, in this paper, we propose a smartphone application that records music sound by playing an acoustic guitar, converts it to other instruments' sound, applies effect to the converted sound, and creates a final ensemble music after mixing all sounds. Using the proposed application, the user can create ensemble music only by playing the acoustic guitar.

A smartphone is a mobile phone that offers more advanced computing ability and connectivity than a contemporary basic feature phone. Unlike feature phone, a smartphone allows the user to install and run more advanced applications based on a specific platform. Smartphones run complete operating system software providing a platform for application developers. A smartphone will become the default computing method for many point activities in the not-too-distant future, such as e-mail, online shopping, gaming, and even video entertainment. For smartphone that contains sensitive information and access the Internet, security is a major issue. In the 1980s, security issues were hardly noticed; however, security is a major issue for users today, which includes smart phones. Because security is much more difficult to address once deployment and implementation are underway, it should be considered from the beginning. Recently our government recognized the importance of smartphone security and published several safety tips for using the smartphone. However, theses tips are user-oriented measures. Maintaining the security of a smartphone involves the active participation of the user. Although it is a important users understand and take full advantage of the facilities afforded by smarphone, it is more important developers distribute the secure smartphone application through the market. In this paper we describe some scenarios in which user is invaded his/her privacy by smartphone stolen, lost, misplaced or infected with virus. Then we suggest the security considerations for securing smartphone applications in respect with developers. We also suggest the methods applying domestic encryption algorithms such as SEED, HIGHT and ARIA in developing secure applications. This suggested security considerations may be used by developers as well as users (especially organizations) interested in enhancing security to related security incidents for current and future use of smartphones.

The purpose of this study is to develop a cancer rehabilitation program for cancer survivors in the form of a smartphone application and to confirm the effectiveness through Pilot study. The contents of the application consisted of health records, lab-test records, and health information, and the information recorded by the patient was graphically checked for changes over time on my page. 7 subjects who ended acute treatment and were undergoing follow-up were asked to use the application for 4 weeks, and then changes in variables (uncertainty, e-health literacy, self-efficacy, and cancer rehabilitation) were confirmed. It was confirmed that e-health literacy and self-efficiency increased significantly over time after using the application. In addition, the level of cancer rehabilitation was found to increase significantly over time. The application for cancer rehabilitation developed in this study needs to be expanded to improve the quality of life of cancer survivors.
