The various kinds of application is distributed for the Smart phone user recently. There is the advantage that the open source application on Android operating system based Smart phone supports a multi tasking service. Layar, Wikitude, and Sherpa and the other applications using the GPS location information like an a2b etc. were developed in the Smart phone environment. However, the existing Cell-ID based location information can be directly collected by the mobile ISP unit which the mobile carrier installs, the personal privacy problem occurs. Therefore, the personal location information is possible to be exposed publicly without any access control procedure. Therefore, in this research, the self-control mechanism on the GPS location information at the Smart phone is designed and presented. Through this, it is possible to develop diverse applications providing enhanced access control and GPS location management on the Android based Smart Phone.

Smart phones are very convenient for communication, but you need to not to forget to change to silent mode when you go to church or cinema. Many people used to forget changing their cell phones to silent mode. In this paper, we have developed an android smart phone app. for automatic changing silent mode, which exploited smart phones' GPS and computing capability. According to the GPS location data and time, this app. will automatically change a cell phone to silent mode. We believe that this app. would provide us a lot of convenience.

In the past, the domestic research on mobile forensics has been limited to cell phones. Increasing use of smart phones, studies on smart phone forensic will be conducted actively in the future. In particular, the study on Android forensic is very important because Android smart phone market share is increasing rapidly. In this paper, we describe an implementation of an Android smart phone forensic tool based on logical analysis. Compared with Oxygen Forensic Suite 2010, this tool saves time it takes to perform Android smart phone forensic because this tool provides search feature and resource links for extracted media information. So far, no smart phone forensic tool is introduced in Korea. Accordingly, this tool would contribute to the advancement of the technology on smart phone forensic.

A cell phone is a necessity for the modern society. The function of mobile phone enables us to exchange various information beyond the time and space. In addition it has lots of function such as shooting of moving picture. This study is to research the accuracy and rapidity of the information by means of SMS, and to propose a new system of transmission in order to create a profit for the life economy. Through the function, which is suggested in this paper, we can store the phone number to the sending category of the other party's phone by combining character or number. We can expect the most accuracy and swiftness of the cellphone information via of this proposed research.

Background: Breast cancer is the most common cancer and the second principal cause of cancer deaths among women worldwide, including Malaysia. This study focused on media choice and attempted to determine the communication channels mostly used and preferred by women in seeking information and knowledge about breast cancer. Materials and Methods: A cross sectional study was carried out to examine the breast cancer prevention information seeking behavior among 450 students at one private university in Malaysia. Results: The mean age of respondents was $25{\pm}4.3years$. Common interpersonal information sources were doctors, friends, and nurses and common channel information sources were television, brochure, and internet. Overall, 89.9% used cell phones, 46.1% had an interest in receiving cell phone breast cancer prevention messages, 73.9% used text messaging, and 36.7% had an interest in receiving text breast cancer prevention messages. Bivariate analysis revealed significant differences among age, eduation, nationality and use of cell phones. Conclusions: Assessment of health information seeking behavior is important for community health educators to target populations for program development.

This paper presents a behavioral data monitoring system based on WAP(wireless application protocol) service for the 24-hour continuous health state monitoring of the elderly and the disabled. The developed system transmits a character message to the predefined mobile cell phone through SMS service when an emergency state takes place. Simultaneously, the image captured by a CCD camera is transmitted to the server computer installed WAP service program. Then, the user of the cell phone who received he message can access the server and open the transmitted image. This system can be used for the effective health monitoring of the elderly and disabled.

In this paper, we design and develop a personalized advertisement and information services system based on mobile RFID using RFID virtual tag. It is a system to perform the use of the contents information or the commercial transaction on the contents products through internet server connection by using RFID tag information with a mobile according as transmitting immediately to a cell phone after a tag generator derived RFID tag information to be substituted for the contents information being output at present, after being transmitted from a cell phone the information request signal on the contents information being output from video media. This service system provides a mechanism for gathering advertisement information left behind by many clients visiting advertisement sites for analysis of customers property, service model for selecting personalized services, and mechanism for providing them to customers who visited in a advertisement mall joined to the shopping site.

At the stage of content convergence into cell phone, technologies for geo-spatial information sharing and searching are being developed. Currently, 2D portable navigation map for mobile navigation is provided by communication companies, but geobrowers for 3D geo-information in cell phone are under developing. In this study, 3D feature transformation among X3D-M3G-KML, on mobile and web environments, is dealt with as the first stage for the further mobile 3D web application. As well, it is possible to real-time interoperable 3D geo-information exchange issues within both environments.

This paper is concerned with a protection system for the mentally handicapped, which is utilizing a GPS receiver and mobile communications. The protection system consists of a location notification equipment, a location identification and management server, and a cell phone of guardian. The location notification equipment is made up of a GPS receiver, a CDMA communication module and a microprocessor. The equipment transfers the location of the mentally impaired to the location identification and management server when the handicapped gets out of a certain bound of the designated facility. The server marks the handicapped's location on the map in the server and also notifies the guardian's cell phone of the locations. With applying the proposed protection system to social welfare organizations related to the mentally handicapped, it is expected to efficiently contribute to the promotion of the handicapped's welfare.
