In order to improve user accessibility and interactivity, system scalability, service speed, and a non-standard internet web environment, we developed a Web-based geovisualization system of oceanographic information using HTML5 and dynamic particles. In particular, oceanographic and meteorological data generated from a satellite remote sensing and radar measurement and a 3-dimensioanl numerical model, has the characteristics of a heterogeneous large-capacity multi-dimensional continuous spatial and temporal variability, based on geographic information. Considering those attributes, we applied dynamic particles represent the spatial and temporal variations of vector type oceanographic data. HTML5, WebGL, Canvas, D3, and Leaflet map libraries were also applied to handle various multimedia data, graphics, map services, and location-based service as well as to implement multidimensional spatial and statistical analyses such as a UV chart.

The video conference system which enables multiple users even at places away from each other proceed with the work at the same time is required to establish a convenient and efficient smart work environment. The conventional S/W-based video conference system is developed by the different implementation methods using provider's own technology and as a separate program for each OS type of user. On the other hand, the video conference system using HTML5 and WebRTC provides features of video conference system through a web browser that support HTML5 and WebRTC functions without installing any programs In this paper, in order to activate a HTML5-based video conference system in the domestic market, we propose the standard for the interworking functions that need to be supported in each system to ensure the interoperability among different HTML5-based video conference systems.

In the distance education system existing, change of content by the content provider has not been performed in real time. But current car model is changed quickly. So it must modifying by contents provider in real-time. In this paper, we implement contents authoring system for modifying E-training contents easily. Especially, it use HTML5 technology. Through it, contents providers can modifying contents in various platforms easily.

In this paper, the standardization of the Web technology of HTML5/CSS3 and JQuery Mobile, using a variety of mobile platforms, run independently within an environment as possible to implement the Mobile Office System. In addition, user friendly Web interface and dynamic web design through a mobile device in a Mobile Office system provides convenience to the user when a hybrid Web application based mobile office system implement.

웹의 점진적 발전에 맞춰 웹 프로그래밍 언어도 계속적으로 발전해 나아가고 있으며, 기존 HTML에서 더욱 진화된 HTML5는 다양한 멀티미디어 기능과 그래픽 효과를 표현할 수 있다. 최근 각 분야에서 인터넷 활용이 점점 증가하고 있는데, 투표방식에서도 전통적인 방식에서 인터넷을 활용한 인터넷 투표 방식을 도입하려는 사례가 늘어가고 있다. 인터넷 투표는 부정투표와 같은 보안적 문제점이 있는데, 본 논문에서는 HTML5를 기반으로 JSP를 이용하여 인터넷 투표의 보안성을 강화하고 HTML5에 기반 한 기술을 활용하여 시스템을 구축하였다.

Web Information Systems have many static HTML documents and dynamic CGI application programs. A hyperlinked information environment on Web systems include lots of mutually referenced documents. This cause problems of data consistency in a intra-document and among inter-documents. To solve the problems, we propose a management method of Web system which have hierarchical information structure, and an unified problem-solving approach. We construct a large scale practical Web system based upon the proposed architecture. The proposed results can provide many advantage to WebMasteters.

Real-time video communication technology of hybrid Web-based using JavaScript and HTML5 today is on the rise. Therefore, in this paper, we have studied the real-time videoo communication technology using a Web browser that supports HTML5. It has been designed and implemented a system based on HTML5 and JavaScript, allowing for video communication of real-time, such as you would using the HTTP/WebSockets and RTC API through the Web servers in the Web browser between different each other, utilizing a Web browser was. It is available in a usable terminal equipment of a Web browser PC or notebook, smart pad, such as a smart phone, which is available without installation, such as a plug-in register or another. In all environments the network is connected, it is available in all terminals use the Web browser is enabled, which will be utilized in the field of video communication in a restricted environment.

HTML5는 웹 표준규격으로서 월드 와이드 웹에서 구현되는 기존의 HTML의 문법적 오류를 바로잡고, 점차 작업환경이 웹 기반의 환경으로 넘어오는 시대에 맞추어 더 화려한 그래픽 표현을 별도의 플러그인 없이 간편하게 웹 브라우저에서 구현 가능할 수 있도록 하는 언어이다. 본 논문에서는 이를 이용한 플랫폼으로 웹 상에서 전문적인 헬스 트레이너와 양방향 커뮤니케이션이 가능한 사용자 맞춤형 헬스서비스 관리시스템을 제안하고 구현하여 시간, 장소에 관계없이 개인에 맞는 헬스 관리를 가능하게 한다.

ActiveX는 DLL(C/C++ 컴포넌트) 연동과 로컬 리소스를 사용하여 웹의 한계를 극복할 수 있는 웹 애플리케이션을 기술이다. 최근 까지 국내에서 널리 활용되어 왔지만 호완성과 보안문제로 인해 폐지될 예정이다. 현재 HTML5가 대안으로 고려되고 있지만 지원되는 API 안에서만 자유롭고 DLL(C/C++ 컴포넌트) 호출이 불가능하기 때문에 ActiveX를 완벽하게 대체하기는 사실상 불가능하다. 따라서 본 논문에서는 기존의 ActiveX의 DLL(C/C++ 컴포넌트) 코드를 재활용하기 위해 GNU 빌드 시스템과 통합 빌드 시스템을 통해 코드 의존성을 분석하고 LLVM을 통해 비트코드로 컴파일한 후 최종적으로 Emscripten을 통해 자바스크립트 코드로 재활용하는 시스템을 설계 하였다.
