This paper presents a design of Android-based car application. We analyze the fuctinons on the main car applications(e.g., HUDY, Easy car Finder, DailyRads Voyager). In additon, we suggest the functions which these don't have. We use the devices(GPS, camera, and sensor), Google map, Location Based Service, and SQLite Database. GPS devices are used to implement the driving speed. Camera records the driving images. Google map and Lacation-Base Services can replace a navigation functions. Database SQLite can be recorded all kinds of the driving information. 본 연구는 안드로이드 기반의 자동차용 애플리케이션의 설계에 관한 논문이다. 먼저, 현재의 안드로이드 마켓에서 차량에 관한 주요 애플리케이션 HUDY, Easy Car Finder, DailyRoads Voyager의 기능을 분석하고 이들이 보유하지 않은 기능에 대해 추가적인 설계를 제안한다. 이를 위해 GPS, 카메라, 센서등과 같은 디바이스와 구글 맵, 위치 기반 서비스, SQLite 등을 활용한다. GPS를 사용하여 주행정보의 속도를 구현하고, 카메라를 이용하여 주행영상을 기록하며, 구글 맵과 위치기반 서비스를 활용하여 내비게이션의 기능을 대체토록 하였다. 또한 데이터베이스 SQLite를 이용하여 주행 정보를 기록하도록 하였다.

Purpose : The purpose of this study was to investigate the effects of abdominal functional electrical stimulation on peak cough flow and forced vital capacity in patients with cervical spinal cord injury. Methods : The study examined 20 patients with cervical spinal cord injury. The subjects were randomly divided into two groups. All subjects performed conservative physical therapy for 30 minutes. The experimental group also underwent abdominal functional electrical stimulation for at least 20 minutes per day. Abdominal functional electrical stimulation was applied to the rectus abdominis muscle twice each day, three times a week, for four weeks. In all subjects, the peak cough flow was measured using a peak flow meter and forced vital capacity was assessed using a spirometer. Results : The experimental group showed a significant increase in peak cough flow and forced vital capacity in pre-post measurements (p<.05), while the control group showed a significant increase only in peak cough flow. Conclusion : These findings suggest that conservative physical therapy in combination with the abdominal functional electrical stimulation can improve peak cough flow and forced vital capacity in patients with cervical spinal cord injury.
