  • Mobile spam message is a harmful factor which makes receivers to be annoyed and leads to unnecessary social cost. Unwanted junk messages flowing to a smart phone ruin main purpose of the smart work system to enhance the productivity, so we need to study on this area. In this paper, we proposed a novel spam filter on the smartphone in order to reduce computing process and improve the accuracy rate by feedback of error results to a training sample set. As the spam classifier operates on the smartphone independently with training on only user's received data, it could reflect user preference. The authorized personal computer takes on heavy works, such as preprocessing, feature selecting and training process, and the smartphone takes on light works to block junk messages. Experimental results showed reasonable accuracy rate of over 95%, and we found that the application occupied constant computing resources while running on the phone.

  • 인터넷을 이용하여 전광판의 메시지를 원거리에서 손쉽게 변경할 수 있는 전광판 원격제어시스템을 구현하였다. 본 논문에서 구현한 시스템은 ARM720T코아가 내장된 EP7312를 CPU로 사용하였고 커널이미지를 저장하는 NOR Flash, SDRAM과 시리얼 포트, Ethernet 보드 등으로 구성하였다. 이 하드웨어에 리눅스 커널 2.4.1을 포팅(Porting)하고 리눅스 응용프로그램이 리눅스 상에서 실행되도록 하였다. 이렇게 구현된 전광판 원격제어시스템이 작동하면 리눅스가 부팅(Booting)되면서 응용 프로그램이 실행되어 Ethernet보드로 문자 데이터를 받을 수 있도록 초기화하고 데이터가 들어오기를 기다린다. 원거리에 있는 클라이언트 컴퓨터가 전광판 원격제어서버시스템에 접속하여 문자데이터를 전송하면 이 시스템은 Ethernet보드로 그 데이터를 받아서 다시 시리얼 포트에 연결된 전광판으로 보내는 기능을 한다. 그리하여 인터넷으로 원거리에 있는 전광판의 메시지를 클라이언트 컴퓨터에서 전광판 원격제어시스템으로 접속하여 문자를 입력받아 전송할 수 있는 프로그램을 이용하여 손쉽게 변경하였다.

  • Purpose: The purpose of this study was to determine the effects of self-care program using Short message service (SMS), e-mail, or telephone call on self-care compliance and nutritional status in maintenance of hemodialysis patient. Methods: Nonequivalent pretest-posttest control experimental design was used. Ninety-six patients were allocated to control (n=24), SMS (n=24), e-mail (n=24), or telephone (n=24) group from four hospitals. Experimental groups received self-care program about hemodialysis diet, drug administration, exercise, and fistula care by SMS, e-mail, or telephone call respectively at 3 times a week for 4 weeks. Results: Subjective self-care compliance, and objective self-care compliance including interdialytic weight of SMS and telephone groups were significantly increased than those of control groups. However, nutritional status of SMS and e-mail groups were significantly improved than those of control groups in albumin and protein level. Conclusion: Self-care program using SMS and telephone call were effective on promoting self-care compliance, while SMS and e-mail were effective on improving nutritional status. The pop-up remaining effect and easy accessible effect of SMS message in busy daily life was considered as an alarm to control fluid and diet.

  • In this paper, a detection technique of smishing using a TaintDroid is suggested. Suggesting system detects malicious acts by transmitting a URL to the TaintDroid server and installing a relevant application to a virtual device of the TaintDroid server, when a smartphone user receives a text message including the URL suspected as a smishing. Through this we want to distinguish an application that can not install because of suspicion of a smishing in an actual smartphone whether said application is malicious application or not by testing with the virtual device of said system. The detection technique of a smishing using the TaintDroid suggested in this paper is possible to detect in a new form a smishing with a text message and to identifying which application it is through analysis of results from a user.

  • Purpose: This study is designed as a non-equivalent, control group pre/post-test for identifying effectiveness of a workplace walking program using a fitness tracker including individual counseling and tailored text messaging. Methods: Seventy-nine employees from two large companies were allocated into an intervention group (n=39) and a control group (n=40). Participants were asked to wear a fitness tracker (Fitbit Charger HR) during 24-hour, 5-days per week, for 10 weeks. The intervention group was provided with daily walking steps measured by Fitbit, weekly counseling with a specifically designed workbook, and seven weekly text messaging, and the control group with the fitness tracker only. Results: At the week 10 measurement, there were significant differences between the intervention and control groups in physical activity self-efficacy (p<.001), physical activity behavior (p<.001), daily walking steps (p<.001), systolic blood pressure (p=.033), and wellness (p<.001). Conclusion: These results suggest that the workplace walking program using a fitness tracker including individual counseling and tailored text messaging is more effective for persons with 10,000 steps/day. Therefore, it is recommended to actively apply this workplace walking program to inactive employees for encouraging regular physical activities and improving their wellness.

  • The Disaster text service is a text-based service for public alert. But, foreigners who are not familiar with korean can not understand exactly the disaster text messages provided. Using multimedia information such as images is expected to solve this problem. However, the current disaster message service method is not suitable for multimedia information delivery. This study proposes a firmware-based disaster character service method for displaying disaster image in a terminal. A device using this method should store images corresponding to the type of disaster and use special characters to inform the presentation of image in a terminal. This approach can be implemented in the new firmware installed device and it can be work with the existing device.
