  • 대부분의 스마트폰 이용자들이 모바일 인스턴트 메신저를 매일 사용하는 것으로 조사될 만큼 모바일 네트워크는 필수적인 상호통신의 도구가 되었다. 본 논문에서는 회사 내 구성원들의 상호통신을 위해 데스크 탑 컴퓨터에서 보편적으로 사용되고 있는 사내 메신저를 다양한 플랫폼을 가진 각종 모바일 장치들과 데스크 탑 컴퓨터에서 공통적으로 사용할 수 있도록 유무선 통합 웹 메신저로 개발하였다. 독립된 여러 회사를 복수조직이라 정의하고, 복수 조직을 하나의 메신저로 묶어 복수 조직의 구성원들이 서로 통신해야 되는 특수한 형태의 회사 조직을 대상으로 개발하였다. 따라서 특정 부서의 보안을 위해 웹 메신저 내 서로 다른 조직의 특정 부서로의 접근을 제한하는 기능이 있다. 개발된 웹 메신저는 안드로이드, iOS 플랫폼 및 데스크 탑 기반의 다양한 웹브라우저들에서 매우 안정적으로 작동하였다.

  • 지금껏 비교적 많은 웹 디자인 가이드라인이 있지만 대부분의 가이드라인은 확인 실험을 거치지 않은 디자이너의 직감이나 상식 에 바탕을 둔 것이 대부분이다. 본 논문에서는 효율성 위주로 하는 사용성 중심의 디자인 방법에서 벗어나 웹사이트의 목적 에 부합하는 감성을 사용자로부터 이끌어 내는 디자인 방법론을 제시하기 위해 I.R.I 색채 연구소의 감성 모형을 통한 색채 계획을 웹 디자인에 적용하여 제작자와 사용자간의 색채를 통한 감성 커뮤니케이션을 향상시킬 수 있는 방안을 제시하였다.

  • This paper is about a system development which control and monitor a PLC of the remote-distance through the Internet using the web-browser. In general, the PLC uses its own communication protocol of PLC Manufacture. It is actually impossible to be used through the Internet, because the PLC communication protocol is basically developed to be suitable for short-distance. Therefore, what we need is a transformation system which can convert the PLC communication protocol into the form which can connect to the Internet. In that sense, this paper is that about remote-control method through the WWW ( World Wide Web ). This system have three characteristics. First, it is possible to connect the Internet directly irrespective of CPU, Operating system and browser. Second, it is easy for user to access and treat. Third, it needs only HTML to operate without java or plug-in expansion. In this paper, we will introduce the monitoring and control system of PLC on the Linux with the Apache web-server.

  • Application layer attacks have for years posed an ever-serious threat to network security, since they always come after a technically legitimate connection has been established. In recent years, cyber criminals have turned to fully exploiting the web as a medium of communication to launch a variety of forbidden or illicit activities by spreading malicious automated software (auto-ware) such as adware, spyware, or bots. When this malicious auto-ware infects a network, it will act like a robot, mimic normal behavior of web access, and bypass the network firewall or intrusion detection system. Besides that, in a private and large network, with huge Hypertext Transfer Protocol (HTTP) traffic generated each day, communication behavior identification and classification of auto-ware is a challenge. In this paper, based on a previous study, analysis of auto-ware communication behavior, and with the addition of new features, a method for classification of HTTP auto-ware communication is proposed. For that, a Not Only Structured Query Language (NoSQL) database is applied to handle large volumes of unstructured HTTP requests captured every day. The method is tested with real HTTP traffic data collected through a proxy server of a private network, providing good results in the classification and detection of suspicious auto-ware web access.

  • The Internet has been expanded constantly and greatly such that we are having vast number of web pages with dynamic changes. Especially, the fast development of wireless communication technology and the wide spread of various smart devices enable information being created at speed and changed anywhere, anytime. In this situation, web crawling, also known as web scraping, which is an organized, automated computer system for systematically navigating web pages residing on the web and for automatically searching and indexing information, has been inevitably used broadly in many fields today. This paper aims to implement a prototype web crawler with Python and to improve the execution speed using threads on multicore CPU. The results of the implementation confirmed the operation with crawling reference web sites and the performance improvement by evaluating the execution speed on the different thread configurations on multicore CPU.

  • In this paper, "The PLC Controlling on Web Browser" is designed and implemented to remote control and to monitor FA system. Protocol bidirectional communication with PLC is written and sotted. Then Administration system sets Web server and JAVA Sevelet Program. The client system located at the monitoring Web browser are a JAVA Sevelet base system, and sends some commands to the server system which guards and controls the PLC system. The commands are delivered to the server system and the driver software exists in the server controls the PLC system directly.

  • The web is one of the most plentiful sources of images. The web has an immediate need for image processing technology in Java. This paper provides a practical introduction to statistical image processing using Java on the web. The paper describes how images are represented in Java and deals with four image processing operations based on basic statistical methods: point processing, spatial filtering, edge detection and image segmentation.

  • Communication is a process involving a group of interrelated elements working together for the purpose of information transfer. This paper discusses information retrieval as a communication process in the 21st century library. The difficulties associated with access to recorded knowledge through bibliographic control devices have been exacerbated by the interposition of additional encoding processes in the library and further decoding by the users. In addition, the innovation of internet/web has revolutionized the means and mode of communication process in the library by flooding information seekers with information and creating an illusion of self-sufficiency in many users. With these changes in information seeking behaviour and pattern, a cybernetic approach to information retrieval has emerged emphasizing adaptive control mechanisms and feedback processes. This paper argues that libraries should strive to continuously remain relevant by keeping abreast with changes in the behavior of information users. To this end, this paper proposes apomediatic-cybernetic model of communication, which illustrates information retrieval processes for the 21st-century library.
