종래의 웹 기반 업무 협업 및 프로젝트 관리 방법으로 제공되는 기술은 ActiveX 나 JVM(Java Virtual Machine)을 이용한 특정 프로그램 설치를 통한 방법으로써 특정 플랫폼이나 브라우저에서만 동작하는 방법을 제공하고 있다. 본 논문에서는 통상적인 웹 기반에서 임의의 프로그램 설치 없이 Ajax(Asynchronous Javascript And XML)를 이용하여 웹 기반 업무 협업시스템을 개발하였다.

한때 word process를 하기 위해 PC를 구매하던 때가 있었다. 그리고 지금도 word process 기능은 PC를 쓰는데 없어서는 안 될 기능중 하나이다. 그리고 최근 들어 web2.0의 추세와 함께 일반 application에서 수행하였던 Application들이 Web에서 수행이 가능한 web application으로 변화하고 진화하는 추세이다. 따라서 본 논문에서는 Ajax(Asynchronous Javascript And XML)기반의 공유 word process인 'Ajax기반 공유 word'를 만들었다. 이는 웹에서 WYSIWYG(what you see is what you get)으로 문서를 편집하면서 문서들을 사용자간 공유하고 문서의 변경내용을 다른 사용자가 실시간으로 확인할 수 있는 web application이다.

현재 인터넷상에서 전자상거래의 급속한 성장은 HTML 문서나 Javascript와 같은 웹 문서의 빈번한 전송을 요구하며 이는 현재뿐만 아니라 향후 인터넷 전송 트래픽을 야기하는 주요 요인이 될 것이다. 웹 페이지는 비슷한 문장열이 인수에 해당하는 부분만이 변화되면서 반복하는 특징을 갖고 있다. 본 연구에서는 웹 페이지의 이러한 특징을 이용하여 매크로 기법을 사용한 웹 문서 압축 알고리즘이 웹 페이지의 저장공간 압축에 좋은 성능을 가짐을 보여줌으로써 전송시간의 축소의 부가적인 효과를 거둘 수 있었다.

For improving interoperability of medical information, health level 7 has initiated the development of a next-generation framework for the exchange of medical information called the Fast health interoperability resources (FHIR). However, there was no attempt to exchange the medical three-dimensional (3D) image with clinical data via FHIR. Thus, we designed a new method. The 3D image to be made from computed tomography was converted to the javascript object notation (JSON) file format, and clinical data was added. We made a test FHIR server, and the client used the postman. The JSON file was attached to the body, and was then transmitted. The transmitted 3D image could be seen through a web browser, and attached clinical data was identified in the source code. This is the first attempt to exchange the medical 3D image. Additional researches will be needed to develop applications or FHIR resources that apply this method.

In this paper, we propose IoT based smart CCTV security service to prevent crime in blind spot and prevent unexpected fire or danger. In the proposed method, a RC (Radio Control) car is made using Raspberry pie, and a camera and various modules are installed in an RC car. It was then implemented using Raspbian O / S, Apache Web Server, Shell script, Python, PHP, HTML, CSS, Javascript. The RC car provides a security service that informs the manager of the situation by judging the risk of the scene with modules such as video, voice and temperature. Experimental results show that the transmission time of video and audio information is less than 0.1 second. In addition, real-time status transmission was possible in AVG, emergency, and manual mode. It is expected that the proposed method will be applied to the development of smart city by applying it to unmanned vehicles, drones and the like.

In this paper, design and implementation of RIA(: Rich Internet Application) technology, a CMS based on either of the Adobe Flex framework. Flex existing HTML + CSS + Javascript, etc. it can be easily added to a variety of visual components on a markup language consisting allow you to implement a more dynamic website. The HTTP request is processed using the Spring Framework of MVC based. Spring Framework provides a number of services for the development of a dynamic website to open source framework for the Java platform. It is being used as a standard-based technology for e-government framework used to develop recommendations and Republic of Korea during the Web service public institutions. Extensive production becomes increasingly thin web can be more efficiently managed, and will provide convenience to the user.

As internet becomes widespread, a lot of information is opened to public and users of Internet can access effectively information using web searching service. To construct web searching service, the web searching method for collecting of information is needed to obtain web page view. As a number of web page view increases, it is necessary to collect information of high quality information to be searched, therefore, a variety of web engine for searching mechanism is developed. Method of link extraction with javascript in dynamic web page and design of web searching robot are presented m this paper. To evaluate performance analyzes, we fixed one searching model with the proposed method. The searching time takes 2 minute 67 sec for 299 web pages and 12.33 sec for 10 searching model.

A hierarchical Web Security System, which is a solution to various web-based attacks, seemingly is not able to keep up with the improvement of detoured or compound attacks. In this paper, we suggest an efficient detecting scheme for web-based attacks like Malware, XSS, Creating Webshell, URL Spoofing, and Exposing Private Information through monitoring HTTP outbound traffics in real time. Our proposed scheme detects web-based attacks by comparing the outbound traffics with the signatures of HTML tag or Javascript created by the attacks. Through the verification analysis under the real-attacked environment, we show that our scheme installed in a hierarchical web security system has superior detection capability for detoured web-based attacks.
