ActiveX와 같은 비표준 기술에 기반을 둔 인터넷 환경을 개선하기 위해 국제 웹 표준 활용 기술인 HTML5의 전환이 진행되고 있다. 웹 페이지를 만들기 위한 기본 프로그래밍 언어인 HTML5 (Hyper Text Markup Language 5)는 HTML4보다 보안을 고려하여 설계되었다. 그러나 새롭게 추가된 신기술들로 인해 웹 기반 취약점에 대한 공격 범위가 넓어졌으며, HTML4 환경에서 발생하던 다양한 보안 위협들이 그대로 상속되고 있다. 본 논문에서는 스크립트 기반 사이버 공격 및 HTML5 기능 악용 스크립트 중 개인정보 침해가 발생할 수 있는 부분에 초점을 두었으며, 어떤 공격에 악용되어 개인정보가 침해되는지 실제 재현하였다. 또한, 개인정보 침해를 유발하는 공격에 대해 클라이언트 기반으로 진단 가능한 플러그인 타입의 탐지 모듈을 구현하였다. 진단 스캐너를 이용한 공격 탐지는 HTML5 기반 웹 어플리케이션이나 웹 페이지에 대한 신뢰도를 자가 진단한 후 웹 서비스를 이용하므로 HTML5의 취약점 공격에 대해 사전대응이 가능하며, 새로운 취약점 발생 시 탐지 기능 추가가 자유로워 확장성이 용이하다.

본 논문에서는 AJAX(Asynchronous JavaScript And XML)를 이용하여 태양광 인버터의 모니터링 시스템을 구현하고자 한다. AJAX는 DHTML(Dynamic Hyper Text Makeup Language)과 다른 자바스크립트 기술 등과 함께 RIA(Rich Internet Application)를 만들 수 있는 기술 중 하나이다. 이를 사용하여 일반 응용프로그램에 필적하는 강력한 응용프로그램을 만들 수 있다. 기존의 데이터 처리 기법으로는 동일 페이지에서 데이터의 Request와 Response를 동적으로 처리할 수 없다. 하지만 비동기 통신 방법인 AJAX 기반 기술을 이용하면 직관적이며 데이터 변동 상태를 실시간으로 제공하기 때문에, 한 페이지 내에서 모든 기능을 실행할 수 있고 페이지 전환 없이 데이터 전송량이 현저히 작은 AJAX를 사용하여 효율적인 관리 및 모니터링 할 수 있기 때문에 태양광 인버터모니터링 시스템에 AJAX를 적용하여 효율적인 모니터링 시스템을 구현하였다.

본 논문에서는 e-비즈니스 DTD(Document Type Definition) 문서를 기반으로 한 XML 폼 생성기(Form Generator)를 설계 및 구현하였다. 인터넷 보급과 정보환경 변화는 e-비즈니스에 있어서 많은 변화를 제공하였고, 거래에 사용될 비즈니스 문서 양식에 있어서도 웹 형식이거나 전자화된 전용 양식 형태로 변환될 필요가 있게 되었다. 이러한 상황에서 각각의 업체별로 다양한 문서 포맷을 사용하여, 상호주체 간에 포맷 호환성 제공을 위한 필요성이 제기되며, 따라서 재사용성과 포맷 호환성 지원에 따른 비용의 문제를 안고 있다. 이에 따라, 논문에서 제안하는 XML 폼 생성기는 XSLT를 이용하여, 생성 결과인 XML 폼 문서에 HTML(HyperText Markup Language) 형태의 웹 문서로 생성 후에, 사용자 입력을 통해 e-비즈니스 DTD 문서 구조에 유효한 XML 비즈니스 메시지를 작성할 수 있다.

In this paper, It is studied to control and to monitor the remote system state using HTTP(Hyper Text Transfer Protocol) object communication. The remote control system is controlled by using a web browser or a application program. This system is organized by three different part depending on functionality-server part, client part, controller part. The java technology is used to composite the server part and the client part and C language is used for a controller. The server part is waiting for the request of client part and then the request is reached, the server part saves client data to the database and send a command set to the client part. The administrator can control the remote system just using a web browser. Remote part is worked by timer that is activated per 1 second. It gets the measurement data of the controller part, and then send the request to the server part and get a command set in the command repository of server part using the client ID. After interpreting the command set, the client part transfers the command set to the controller part. Controller part can be activated by the client part. If send command is transmitted by the client part, it sends sensor monitoring data to the client part and command set is transmitted then setting up the value of the controlled system.

Because the education system that based on objective data is needed for the beginning technologists in the department of medicine laboratory, development of the CAI system based on Gram-Stain images is needed in clinical microbiology field. So, in this study, we implemented CAI system based on Gram-Stain images for medical technologists under Web using multimedia toolbook. Because this system is implemented under Web, more and more beginning technologists can have a remote-education beyond time and space, can save human power and time that needed due to hold in common of educational information, and cannot learn mistaken microbiology images because of learning execution based on objective data. Also, implemented system brings a higher interest and a learning effect to medical technologies because of hyper-media method that offered from toolbook. In the future, it will be needed a continuous acceptance of changing knowledge and it will be useful system for technologist in case of applying various examinations based Gram-Stain method of this study.

This paper describes a message model based on XML (eXtensible Markup Language) to present real-time data from sensors and instruments at manufacturing processes for web service. HTML (Hyper Text Markup Language) is inadequate for describing real-time data from process control plants while it is suitable for displaying non-real-time multimedia data on web. For XML-based web service of process data, XML format for the data presentation was proposed after investigating data of various instruments at steel-making plants. Considering transmission delay inevitably caused from increased message length and processing delay from transformation of raw data into defined format, which was critical for operation of a real-time system, its performance was evaluated by simulation. In the simulation, we assumed two implementation models for conducting the transformation function. In one model, transformation was done at an SCC (Supervisory Control Computer) after receiving real-time data from instruments. In the other model, transformation had been carried out at instruments before the data were transmitted to the SCC. Various tests had been conducted under different conditions of offered loads and data lengths and their results were described.

The burgeoning distribution of smartphone web applications based on various mobile environments is increasingly focusing on the performance of mobile applications implemented by JavaScript and HTML5 (Hyper Text Markup Language 5). If application software has a simple functional processing structure, then the problem is benign. However, browser loads are becoming more burdensome as the amount of JavaScript processing continues to increase. Processing time and capacity of the JavaScript in current mobile browsers are limited. As a solution, the Web Worker is designed to implement multi-threading. However, it cannot guarantee the computing ability as a native application on mobile devices, and is not sufficient to improve processing speed. The method proposed in this research overcomes the limitation of resources as a mobile client and guarantees performance by native application software by providing high computing service. It shifts the JavaScript process of a mobile device on to a cloud-based computer server. A performance evaluation experiment revealed the proposed algorithm to be up to 6 times faster in computing speed compared to the existing mobile browser's JavaScript process, and 3 to 6 times faster than Web Worker. In addition, memory usage was also less than the existing technology.

This paper discusses the development of the educational simulator for the electricity spot market in korea. The interaction between lectures and users can be much enhanced via the web-based programs which result in the student's teaming effectiveness on an electricity spot market. However the difficulties for developing web-based application programs are that there can be the numerous unspecified users to access the application programs. To overcome the aforementioned multi-users problem and to develope the educational simulator, we have revised the system architecture, the modeling of application programs, and database which efficiently and effectively manages the complex data sets related to an electricity spot market. The developed application program is composed of the physical three tiers where the middle tier is logically divided into two kinds of application programs. The divided application programs are interconnected by using the Web-service based on XML (Extended Markup Technology) and HTTP (Hyper Text Transfer Protocol) which make it possible the distributed computing technology.

The fourth industrial revolution, internet of things, and the expansion of online web services have increased an exponential growth and deployment in the number of cloud data centers (CDC). The cloud is emerging as new paradigm for delivering the Internet-based computing services. Due to the dynamic and non-linear workload and availability of the resources is a critical problem for efficient workload and resource management. In this paper, we propose the particle swarm optimization (PSO) based gated recurrent unit (GRU) neural network for efficient prediction the future value of the CPU and memory usage in the cloud data centers. We investigate the hyper-parameters of the GRU for better model to effectively predict the cloud resources. We use the Google Cluster traces to evaluate the aforementioned PSO-GRU prediction. The experimental shows the effectiveness of the proposed algorithm.
