Due to the development of the digital technology, the territories of broadcasting and telecommunications are being converged and there have been the efforts to eliminate the spatial and/or temporal restrictions in utilizing the services (usually implemented as applications) via various devices (e.g. smart-phone, smart TV, pad-computer, etc). In the circumstances, Web is coming to the fore as a common running platform of the services and the digital broadcasting receivers are pressed to run Web applications as well as Java applications, which are the standard of data service of the digital broadcasting. The paper introduces a platform for running HTML5-based Web applications, which is equipped with a Web kernel (an engine for running HTML5 Web applications), a Web desktop (the facilities (with an UI similar to Window OS) for managing Web applications), and SDK (a set of API's for Web application developers).

Google Maps have changed the response time of Web-GIS using AJAX technologies. In addition, Google released the Open API named Google Maps API(Application Programming Interface) and it lead to the big paradigm on the Open API, where the SDK(Software Development Kit) and ASP(Application Service Provider) had ruled at the related map market. In short, the Open API has been paradigm-shifting for the web mapping. After this, government, many companies and open source foundations have guided Web-GIS market's growth through releasing the relevant Open APIs. So many comparative analysis on web-mapping API carried out by many researches. However there were no researches that can be applied to our current domestic environments. This paper investigates components of web-mapping API. Then we compare how many components supported and enumerate features for each of those APIs. Finally this paper presents direction of future development of Web Mapping API.

WebDAV is an IETF standard protocol which supports asynchronous collaborative authoring on the Web. The WebDAV Access Control Protocol provides various methods of controlling the resources on a WebDAV server and their properties, helping high-level group activities to be performed through the WebDAV server. In this paper, to provide high level collaboration, we introduce a technique for managing access control over WebDAV resources through the WebDAV Access Control Protocol and describe the development of an access control manager for the CoSlide Collaborative system based on the technique. To provide users with the access control features in an easily understandable manner, the developed technique presents the privileges for performing WebDAV methods instead of the standard privileges in the WebDAV Access Control Protocol. In addition, we present the facility for detecting conflicts between new access privileges on resources and old access privileges on them. We applied the method-based access control management technique to the CoSlide collaborative system. The developed access control manager enables us to create group workspaces with flexible access control strategies for group members and resources.

Absorbed dose dosimetry protocols of high energy photon and electron beams, which are widely used and based on an air kerma calibration factors, have somewhat complex formalism and limitations for improving dosimetric accuracy due to uncertainty of the physical parameters used. Recently the IAEA and the AAPM published the absorbed dose to water-based dosimetry protocol. In this work web-based dose calibration program for IAEA TRS-398 and AAPM TG-51 protocols were developed. This program developed using the Visual C$\#$ language can be used in the internet. User selectable dosimetry protocol on the web allows the absorbed dose to water data of the two protocols at a reference point to be easily compared, and enables to conveniently manage and understand the current status of the dosimetry calibration performed at participating institutions in korea. This program and the resultant database from the web-based calibration can be useful in developing new dosimetry protocols in Korea.

웹 기술이 발달함에 따라 공공기관 웹사이트는 단순한 행정기관의 홍보에서 벗어나 국민과 정부 간의 의사소통의 증거인 동시에 업무의 기록으로서 역할을 담당하고 있다. 따라서 공공기관의 웹사이트들은 공공기록물로 인식하고 보호해야 한다. 하지만 공공기관의 웹기록물 중 하나인 심층 웹기록물은 실시간으로 상이한 페이지를 동적으로 구성하기 때문에 기존의 보존방법과는 다른 수집 보존 활용 기술이 요구된다. 국가기록원은 이러한 특징을 가지고 있는 심층 웹기록물을 장기보존하기 위해서 심층 웹기록물 장기보존 포맷인 KoDeWeb을 연구하고 개발하였다. KoDeWeb은 전자기록물이기 때문에 전자기록물로서 진본성 및 무결성을 보장해야 한다. 본 연구에서는 KoDeWeb의 전자기록물로서의 진본성 및 무결성을 증명하기 위해 국제 전자기록물 표준인 OAIS 참조모델에 KoDeWeb을 맵핑시켰다. 나아가 OAIS표준을 따르고 있는 전자기록물 장기보존 시스템에 KoDeWeb을 사용함으로써, 정부 및 공공기관의 심층 웹기록물 생성 및 수집을 체계화하고, 또한 민간이 운영하는 웹의 심층 웹기록물 장기보존에 활용할 수 있다.

Web services came true a services integration, but the XML document decreases the efficiency or the whole application program with connects frequently in relatively slow communication media like network environment embedded system or use the resource limited small-sized instrument like mobile. Thereupon, ITU-T and ISO/IEC suggested encoding standard of binary XML. In this paper, implementation, of Fast XML encoding system through introduction Fast Infoset algorithm and Fast Schema algorithm for web services increase performance. And, offered of test bed that build of Fast Web Services system through Fast XML Encoder.

웹 접근성이란 장애인, 저사양의 컴퓨터 사용자, 저속 회선 사용자, 노인 등 웹을 사용하는 사용자가 신체적 환경적 요인에 관계없이 웹에 접근하여 이용할 수 있도록 보장하는 것이다. 웹 표준은 표준화기구에서 승인한 개방형 인터넷 표준으로서, 웹 표준의 준수는 기기와 독립적이어서 웹 접근성을 향상시키기 위한 최소한의 선결조건이 된다. 본 논문에서는 얼마나 많은 사이트들이 차세대 웹 표준으로 제안되고 있는 HTML5로 구축되어져 있는가에 대하여 방송통신위원회에서 지정한 국내 주요 100대 사이트와 랭키닷컴(www.rankey.com)의 접속자 수가 많은 국내 100대 사이트들에 대하여 알아보고, 이 웹사이트들에 대하여 웹 접근성 평가를 실시하여 봄으로써 HTML5로 구축되어진 국내 웹사이트들에 대한 웹 접근성 실태에 대하여 알아보았다.

ActiveX와 같은 플러그인으로 돌아갔었던 웹 페이지들은 보안 취약성과 인터넷 익스플로어(IE)의 서비스 종료로 인하여 많은 웹 브라우저들이 플러그인 제거 사업을 진행하였다. 하지만 웹 표준으로 전환하였을 때 생기는 웹 호환성과 보안 문제들이 발생하였다. 이를 해결하고자 호환성과 보안 문제를 훈련 시킨 클라우드 서버를 이용하여 미리 파악하고 진단할 수 있는 웹 페이지 보안 체크 모델을 제안한다. 본 논문에서 제안한 모델을 적용한다면, 웹의 표준 및 호환성과 보안 문제에 대해 더 빠르게 파악하는데 도움을 줄 수 있을 것이다.

After the end of the service of Internet Explorer, the use of ActiveX ended, and the Non-ActiveX policy spread. HTML5 is used as a standard protocol for web pages established based on the Non-ActiveX policy. HTML5, developed in the W3C(World Wide Web Consortium), provides a better web application experience through API, with various elements and properties added to the browser without plug-in. However, new security vulnerabilities have been discovered from newly added technologies, and these vulnerabilities have widened the scope of attacks. There is a lack of research to find possible security vulnerabilities in HTML5-applied websites. This paper proposes a model for detecting tags and attributes with web vulnerabilities by detecting and analyzing security vulnerabilities in web pages of public institutions where plug-ins have been removed within the last five years. If the proposed model is applied to the web page, it can analyze the compliance and vulnerabilities of the web page to date even after the plug-in is removed, providing reliable web services. And it is expected to help prevent financial and physical problems caused by hacking damage.

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.
