Recently, online real-time web accessible mobile devices such as smartphones, tablet PCs and application services have been developing rapidly. Hospitals also need to adopt an efficient information system that can provide decent medical services under mobile computing environments to complete future medical services. This study proposes a system in which a doctor can examine a patient and make out a prescription in a ward on a real-time based on the current Order Communication Systems (OCSs) through mobile interfaces. The proposed system implements mobile web pages using HTML5, instead of a mobile app. Web processing speed can be enhanced using the web socket and web storage functions of HTML5.

This paper explains a web session management system for mobile web environment with BYOD(Bring Your Own Device). This system operates by enhanced secure session token. This system consists of an unique identifier, time stamp, and encryption algorithm. The Unique identifier in this system classifies each mobile device for web security based on mobile environment with BYOD. And the Time stamp in this system that determine session effectiveness for web security. Also the Cipher algorithm in this system that protects session token information for web security. This paper analysis a security of session management system running on mobile web environment using the simulation techniques. The proposed method is more suitable than the other methods under enviroment mobile web environment with BYOD.

Users want to browse and search various web contents with mobile devices which can be used anywhere and anytime without limitations, in the same manner as desktop. But mobile devices have limited resources compared to desktop in terms of computing performance, network bandwidth, screen size for full browsing, and etc, so there are many difficulties in providing support for mobile devices to fully use desktop-based web contents. Recently, mobile network bandwidth has been greatly improved, however, since mobile devices cannot provide the same environment as desktop, users still feel inconvenienced. To provide web contents optimized for each user device, there have been studies about analyzing code to extract blocks for adaptation to a mobile environment. But since web contents are divided into several items such as menu, login, news, shopping, etc, if the block dividing basis is limited only to code or segment size, it will be difficult for users to recognize and find the items they need. Also it is necessary to resolve interface issues, which are the biggest inconvenience for users browsing in a mobile environment. In this paper, we suggest a personalized adaptation system that extracts item blocks from desktop-based web contents based on user interests, layers them, and adapts them for users so they can see preferred contents first.

Web services are key applications in business­to-business, business-to-customer, and enterprise applications integration solutions. As the mobile internet becomes one of the main methods for information delivery, mobile Web Services are regarded as a critical aspect of e-business architecture. In this paper, we proposed a mobile Web Services middleware that converts conventional internet services into mobile Web services. We implemented a WSDL (Web Service Description Language) builder that converts HTML/XML into WSDL and a SAOP (Simple Object Access Protocol) message processor that performs SOAP message handling, chain and handling of server requests. The former minimizes the overhead cost of rebuilding mobile Web Services and enables seamless services between wired and wireless internet services. The latter enhances SOAP processing performance by eliminating the Servlet container (Tomcat), a required component of typical Web services implementation. Our main contributions are to overcome the latency problem of current Web Services and to provide an easy mobile Web service implementation. Our system can completely support standard Web Services protocol, minimizing communication overhead, message processing time, and server overload. Finally we compare our empirical results with those of typical Web Services.

Most Hospitals develop a Medical online appointment system for u-Hospital which system based on Web Application. Web 2.0 technology has good user interface and fast response time in a web service. This paper proposed a Mobile Medical Online Appointment System using Web 2.0 Technology. This system improve the page view, convenient UI and fast response time. We test this system with evermedi, other hospital system in iwebtools service and show that it can improve the efficiency and perfomance. The proposed technology can improve the efficient mobile service because it can be extended to ubiquitous mobile application.

Recently, there has been increasing interest to web access through mobile host due to the explosion of internet mobile terminal such as smart phone. However, small displays of mobile hosts make it difficult to browse the full content of a web page at a time. In order to overcome these limitation, we have designed and implemented Web-based text summarization system. The proposed system can summarize the text for the Web page in which abundant text exist in a page. This can reduce the amount of data transmission and minimize the unnecessary data output during browsing at mobile host. Through implementation, we have confirmed the functions of the proposed system.

This paper proposes show how to support the field-learning by using web and mobile system. This Web Mobile system is to help the users plan, carry out and evaluate a field learning. Usually the field-learning is going through three steps: preparation, actual field activity and post-evaluation activity. The proposing Web-Mobile system supports an integrated methodology to more effectively help, lead and manage this three step field-learning, This effective approach will help the learners develop their creativity, self-control and partnership to each other.

This paper proposes and implements a mobile service and web service integration for utilizing public bicycle sharing system NUBIJA. The NUBIJA system is operated by Changwon City, GyeongNam since 2008 and maintains 247 unattended bicycle sharing terminal on the city. Average users per day of the NUBIJA are more than 8,000 and many users want to get more services from their mobile phones. We implemented realtime mobile bicycle rental and return information service. The informations are acquired from each terminal kiosks and we integrated the information and location based services(LBS) on iOS and Android platform. In this paper, we described an integration services between web and mobile application and shows graphical user interface for highly customized on mobile platforms.
