현재 많은 국가들이 복지를 위해 많은 투자와 지원을 하고 있으며, 이러한 시대의 배경을 바탕으로 복지에 많은 관심이 몰리고 있으며, 연구들이 이루어지고 있다. 전 세계적으로 의료가 발달하면서 인간의 수명은 늘어나게 되고, 노인들의 증가로 인하여, 노인에 대한 복지가 문제가 되고 있다. 이러한 문제를 해결하기 위해서 본 논문에서는 이동에 불편함을 느끼거나, 주기적인 관리나 보호가 필요한 노인들이 집에 있으면서 여러 가지 서비스들을 이용 가능하도록 도와주는 기능을 제공한다. 이 시스템을 사용하는 노인들은 기본적인 혈압이나 몸무게 등 측정과 관련된 서비스를 이용할 수 있고, 기초적인 집안일도 서비스로 이용 받을 수 있다. 또한, 관리자가 집을 방문하고, 관리자는 노인이 설정해 놓은 측정 및 서비스들을 확인할 수 있다.

By using geolocation and maps, we need to trace the path of ourselves, others, or the objects. Until now, we used a native apps development mehod to develop path tracking systems in mobile devices such as smart phones and tablet computers. A disadvantage of this method is that we have to work again to provide the same service on different platforms. Web Apps and Hybrid Apps are developed to recover this disadvantage. Since Hybrid Apps look like Native Apps apparently, users prefer Hybrid Apps to Web Apps. In this paper, we develop a hybrid app which can trace the path on mobile devices. The recently suggested next generation markup language, HTML5, has geolocation features. By using them, we implemented a hybrid app for a path tracking system. First, we create a web app using HTML5, CSS, and JavaScript, Then, PhoneGap, a mobile development framework, is used to convert it to the hybrid app. By implementing hybrid app, various apps which need path tracking can be developed rapidly and effectively, regardless of the mobile devices.

Since domestic and foreign platform companies and mobile carriers adopt and use different kinds of smart platforms, developers should develop or convert contents according to each smart platform to provide a single smart content for customers. It takes long time and a lot of money to convert the conventional smart contents in order to serve other smart platforms. For the reason, more attention has been paid on Smart Cross Platform or Hybrid Platform, the core technologies of OSMU(One Source Multi Use) in which, once a program is coded, it can be executed in any platforms regardless of development languages. As a result, PhoneGap and HTML5 based Sencha Touch have been introduced. In this paper, we developed the smart virtual machine, which is built in smart cross platform based smart devices, unlike Android, iOS, Windows Phone devices being dependent of platforms, and helps to download and execute applications, being independent of platforms. the smart virtual machine supports C/C++, and Java language, being differentiated from JVM by sun microsystems that supports only Java language and .NET framework by microsoft that supports only C, C++ and C#. Therefore, it provides contents developers with the environment where they can get a wide range of options in choosing a language and develop smart contents.
