Recently the market of smart phone applications grows very fast. And users want more various and rich experiments using enhanced smart phone functions. But the development of smart phone applications is not an easy job. Specially to control smart phone sensors can be realized by using each native programming languages in experts level. Moreover the process needs separate development based on each smart phone OS. Development of the Web-based smart phone application using Web Common APIs, known as 'WebApp', is one of solutions to overcome these problems. The method includes interface constructions with HTML, and Web Common API calls and accesses to smart phone device APIs with Java scripts. In this paper, the experience in development of the smart phone e-book application is introduced, which is implemented with comport and OS independent WebApp development method.

This paper presented a mobile application program to help eye movement with mobile devices. It helps to strengthen ocular muscles and improve visual acuity. Users can easily access the program of eye movement type of app program in mobile devices. There were some papers which studied on the eye movement and showed efficient eye movement method for improvement of visual acuity. So here presents programming codes to help eye movement with some specific patterns from some papers and it was implemented by HTML, CSS and javascript. To convert web code to app code, appspresso tool was used.

The objective of this paper is to introduce on a mobile APP called MAMIS(Marine pollution Accident response Mobile Information System) and it's functions. MAMIS was developed by Korea Coast Guard for marine pollution responder in 2012. Users can get information on marine pollution response easily without being restricted by time and place. MAMIS can be operated by smart phones with Android OS and iOS, both of which are the most popular mobile operating systems in Korea. And it has been developed in the form of hybrid APP which combined the functions of mobile APP and mobile WEB. MAMIS is composed of 9 menus, 5 mobile-based ones and 4 web-based ones. The mobile-based menus are on substance information, clean-up skills, response measures, QR code scanning, and volunteer's safety, and the web-based ones on weather information, response equipment, clean-up materials, and SNS.

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.

The web service companies develop the App support technique of the HTML5 base in the smart media system and smart TV competitively while the Web platform of the HTML5 base is legislated with the next generation national standard. It is essential to the web kernel, which is the common library of the operating system including the file, window, resource and network management is provided in order to support the various app developments of the HTML5 base effectually. Additionally, the web application program can support UI/UX function of the desktop user using the web browser and JavaScript drive and administration, window management function, and etc. is needed.

Recently, there has been much interest in the e-Navigation that applies a variety of digital devices to shipboard thanks to the high interest to maritime safety and the rapid development of ICT technologies. The e-Navigation proposes a new ICT paradigm in maritime information service and maritime safety. This study proposes the shore-based maritime information service platform that enables the converged services of various kinds of maritime data and the standard ENC based on IHO S-100. The proposed maritime information service platform enables the harmonized integration, presentation and web services of ENC, sensed data such as AIS, ocean weather and currents, and geospatial data. Also, the platform enables the mobile maritime information service through WebApp or App software operating in mobile devices of smart phone or web pad. Finally, the proposed platform accommodates the standard ENC of the existing S-57 and the new S-101, and the standard web services of WMS and WMTS of ISO 19100 and OGC.

Recently, since fine dust has become a serious social problem, air purifiers are in the spotlight as a countermeasure against this. Therefore, in this paper, we conducted R&D on the Smart Autonomous Moving Air Purifier System. The developed Smart Autonomous Moving Air Purifier can improve the limitations of the standard used area of existing air purifiers and perform an air purification function efficiently. In addition, we developed App and Web-based programs together for convenient use of Smart Autonomous Moving Air Purifier. Easily operate three air purification modes (Selection mode, Autonomous highest zone mode, Autonomous instant purification mode) through the App and conveniently monitor statistical values (Recent data, Total data, Warning) anywhere through the Web. And, we showed through test that the proposed Smart Autonomous Moving Air Purifier is more efficient than existing air purifiers.

Collaboration tools are used widely as non-face-to-face work increases due to social distancing after COVID-19. The tools are being developed in a cross-platform manner with 'Electron', an open source framework based on Chromium, to ensure accessibility on multiple devices. Electron Apps, applications built with Electron framework, store data in a manner similar to Chromium-based web browsers, so the data can be acquired in the same way as the data is acquired from a web browser. In this paper we analyze the data structure of web storage and suggest a method to get the message from Electron Apps focused on collaboration tools such as Jandi, Slack, and Microsoft Teams. For Jandi, we get the message from Cache by using previously developed tools, and in the case of Slack and Microsoft Teams, we get the message from IndexedDB by using the message carving tool we developed.
