The Web2.0(Next Generation Web Service) is receiving attention by computer industry. Therefore Ajax(Asynchonous Javascript And in), a key RIA(Rich Internet Application) technology of Web 2.0 applications, has also been a matter of interest. And multiple Web applications which are based on Ajax are being developed and delivered. This paper deals with 'Scheduler Applications/Services' of the web application that utilize Ajax. Plus, this paper is aimed at developing, Project Management Scheduler and Project Roadmap, using web applications that utilize Ajax.

This paper presents a cloud service called CDLint for checking and analyzing the Javascript code dynamically. The correctness of Javascript code is becoming more important since it can also run on the server side as well as the client side. There are several analysis systems for checking the bad code in JavaScript but they seem like have one or more weaknesses. CDLint is developed based on an existing work named DLint which is a powerful bad JavaScript checker. Compared with similar systems, CDLint shows the best performances with respect to the system extensibility, the freedom to use without installation, the automatic parsing of JavaScript code from website, and the environment configuration for JavaScript code checking.

악성코드 유포를 위해 가장 많이 사용되는 Drive-by-download 공격에는 주로 자바스크립트가 사용되며, 공격자는 탐지 시스템의 우회하고 행위 분석을 어렵게 하기 위해 공격에 사용되는 스크립트를 난독화 한다. 난독화 된 자바스크립트를 탐지하기 위한 여러 기존의 연구들이 있었지만 최소한의 코드가 난독화 되어 있거나 정상 코드와 혼재할 경우 난독화 여부를 판단하기 어려운 한계가 있다. 본 논문에서는 난독화 된 자바 스크립트를 효과적으로 탐지하기 위해 전체 스크립트를 실행 단위 코드로 나눠 분석에 필요한 특징을 효과적으로 추출하는 방법을 제안한다.

This paper is implemented new shopping mall by using Ajax(Asynchronous Javascript and XML) technique which makes loading speed down and user-friendly user interface that is different to other Web sites dependent on only flash technique. So this paper is designed and implemented by using ajax technique that makes confirm with eyes of client instantly and insert/delete goods very easily. Additionally, it makes pay attention to shopping and service convenience by adapting simple drag and drop method.

Internet banking is widely used in our life with the development of the internet. At the same time, phishing attacks to internet banking have been increased by using malicious object to make unfair profit. People using internet banking service in Korea is required to install security modules such as anti-virus and keyboard protection. However phishing attack technique has been progressed and the advanced technique such as memory hacking defeats the security module of internet banking service. In this paper, we describe internet banking security modules provided by Korean internet banks and analyze how keyboard encryption module works. And we propose an attack to manipulate account transfer information using javascript. Although keyboard protection module provides two functions that protect leakage and manipulation of account transfer information submitted by users against the malicious program of hackers. Our proposed technique can manipulate the account transfer information and result html pages.

PIPO is the latest domestic lightweight block cipher announced in ICISC'20, which is characterized by being lightweight to facilitate implementation on IoT with limited resources. In this paper, PIPO 64/128-bit and 64/256-bit were implemented using web-based languages such as Javascript and WebAsembly. Two methods of performance evaluation were conducted by implementing bitsice and TLU, and the performance was compared by implementing Looped written using for statements and Unrolled written for statements. It performs performance evaluations in various web browsers such as Google Chrome, Mozilla Firefox, Opera, and Microsoft Edge, as well as OS-specific environments such as Windows, Linux, Mac, iOS, and Android. In addition, a performance comparison was performed with PIPO implemented in C language. This can be used as an indicator for applying PIPO block cipher on the web.

In this paper, we psropose a virtual information desk using VRML and internet. We review about VRML which can construct a virtual world on the internet. Next, we explain a basic concept of a web-based virtual information desk using VRML and javascript. Implementation details and advantages of the developed system are described also.

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.

As Web based knowledge and technology is needed for librarians in the digital environments, it should be educated through the Department of Library and Information(DLI) courses. For importing the courses in DLI, we go through several preliminary stages. First, the role and duties of web masters in digital libraries are figured out. Second, it is known that the tendency of MLS courses in American universities is toward to adopt the web related subjects, but still not in Korea. Third, the survey finds out the recognition of web masters in Korean university libraries about the functions and abilities web masters. As the results, we suggest several subjects for the web master's training. They are HTML, XML, Window NT and Web Server Management, Javascript and Java, Networks, Mutimedia Programs, Programming, and LINUX.

웹은 초기에 단순한 정적인 문서정보를 공유하는 형태에서 동적 상호작용을 하는 형태로 발전되어 왔다. 특히 HTML5의 출현으로 기존의 HTML에서는 외부 플러그인을 통해서만 구현할 수 있었던 오디오/비디오 등의 멀티미디어 및 SVG와 캔버스를 이용한 2D/3D 그래픽 처리가 가능하게 되었다. 또한 HTML5와 Javascript를 통해 유저와의 상호작용 처리가 강화되었다. 본 논문에서는 이러한 HTML5의 특징을 기반으로 게임을 개발하기 위한 프레임워크를 설계하고 구현하였다.
