정보사회의 중심이 되는 정보네트워크로서 인터넷은 사회의 커뮤니케이션 도구의 역할을 하고 있으며 인터넷을 통한 언어사용은 더 이상 피할 수 없는 현실인 것이다. 이에 본 연구에서는 인터넷상의 언어사용에 대한 이론적 근거를 마련하고, 현재 나타나고 있는 인터넷상의 부적절한 언어사용 실태를 '음운ㆍ표기', '문법', '어휘ㆍ의미'로 나누어 조사$\cdot$분석하였으며, 그 결과를 바탕으로 '디지털적 사고', '이용자 추이', '네티켓과 정보교육' 등이 토론되었다.

The development of data communication and network technology has brought a change to various communications through the internet. Regarding the stable internet service, corporations and Individuals came to require an internet data center in which there is computer equipment and network devices available 24 hours everyday. The internet data center is now on a large scale in its structure and facility, suitable for the internet environment that is under development in various dimensions, and effective for task support, stable facility, capable of space expansion and flexibility, and easiness in ease of maintenance and management, etc. The monitoring center of the data center which is one of the core facilities in the center, special space elements and functions as well as a function of task space are to be put into consideration additionally. This study was to present a proposal for the space elements and environmental design of a monitoring center, which could create an efficient and comfortable room.

In recent days, Internet advertising effects are expanded by the steep increase of the Internet users and the extension of the advertising market will be accelerated through Internet. This paper indicates the importance of Internet advertising and suggests the solution of a network advertising service. The system is divided into an Advertise Server, an Advertiser and a Web Publisher. This study proposes both the collection and the analysis of traffic data in real time. Also, the banner advertising frames not for sale purpose are levelled for the impression using the solution for the banner exchange engine. In addition, with developing the advertising service system by using Active Server Pages, the newest language of server side script will be able to lead the additional supplement of more various profitable functions when it is considered the rapid increment of Active Server Pages.

This paper introduces a new method to solve Similarity Recognition for Cloth Products, which is based on Fuzzy logic and Particle swarm optimization algorithm. For convenience, it is called the SRCPFP method hereafter. In this paper, the SRCPFP method combines Fuzzy Logic (FL) and Particle Swarm Optimization (PSO) algorithm to solve similarity recognition for cloth products. First, it establishes three features, length, thickness, and temperature resistance, respectively, for each cloth product. Subsequently, these three features are engaged to construct a Fuzzy Inference System (FIS) which can find out the similarity between a query cloth and each sampling cloth in the cloth database D. At the same time, the FIS integrated with the PSO algorithm can effectively search for near optimal parameters of membership functions in eight fuzzy rules of the FIS for the above similarities. Finally, experimental results represent that the SRCPFP method can realize a satisfying recognition performance and outperform other well-known methods for similarity recognition under considerations here.

Recently the number of Internet users have been drastically increased with the introduction of WWW browsers, which requires accommodation study of TCP/IP on ATM networks. There are a number of problems in operating IP-over-ATM efficiently because of limited functions and overhead of IP. According to recent research, the alternatives to TCP/IP efficiently because of limited functions and overhead of IP. According to recent research, the alternatives to TCP/IP over ABR or UBR have been suggested, and the required capacity of switch buffer and problems in TCP/IP over ABR have been researched. In this paper, we address problems caused by the features of HTTP traffic and suggest a solution for TCP over ABR. The performance of the methods suggested in this paper is verified through simulation under limited conditions.

A flooding attack, such as DoS or Worm, can be easily created or even downloaded from the Internet, thus, it is one of the main threats to servers on the Internet. This paper presents an online real-time network response system, which can determine whether a LAN is suffering from a flooding attack within a very short time unit. The detection engine of the system is based on the incremental mining of fuzzy association rules from network packets, in which membership functions of fuzzy variables are optimized by a genetic algorithm. The incremental mining approach makes the system suitable for detecting, and thus, responding to an attack in real-time. This system is evaluated by 47 flooding attacks, only one of which is missed, with no false positives occurring. The proposed online system belongs to anomaly detection, not misuse detection. Moreover, a mechanism for dynamic firewall updating is embedded in the proposed system for the function of eliminating suspicious connections when necessary.

In this paper, an improved ($\frac{G^{\prime}}{G}$)-expansion method is proposed for obtaining travelling wave solutions of nonlinear evolution equations. The proposed technique called ($\frac{F}{G}$)-expansion method is more powerful than the method ($\frac{G^{\prime}}{G}$)-expansion method. The efficiency of the method is demonstrated on a variety of nonlinear partial differential equations such as KdV equation, mKd equation and Boussinesq equations. As a result, more travelling wave solutions are obtained including not only all the known solutions but also the computation burden is greatly decreased compared with the existing method. The travelling wave solutions are expressed by the hyperbolic functions and the trigonometric functions. The result reveals that the proposed method is simple and effective, and can be used for many other nonlinear evolutions equations arising in mathematical physics.

LINE, an instant message App with a powerful capability of transmitting various forms of data, has been overwhelmed in Asia since launched in 2011. Due to its popularity, LINE was first used in the 2016 Taiwanese presidential election. This research utilized a functional approach of campaign communication discourse and political visual images to analyze how candidates managed and presented themselves by textual and visual information on LINE. Regarding the textual information, results revealed their strategy inclined to reverse gender stereotype because the female candidate emphasized policy over character, while the male emphasized character over policy. Both candidates did not fully employ ten image functions because they utilized mostly the emotional and image building functions. The female candidate message achieved the largest total amount of 'like' and 'share'. This study probes into the App campaigning and improve the feasibility and practicability to share knowledge of political communication by new media.

A variety of reconstruction methods has been developed to convert a set of scattered points generated from real models into explicit forms, such as polygonal meshes, parametric or implicit surfaces. In this paper, we present a method to construct multi-scale implicit surfaces from scattered points using multiscale kernels based on kernel and multi-resolution analysis theories. Our approach differs from other methods in that multi-scale reconstruction can be done without additional manipulation on input data, calculated functions support level of detail representation, and it can be naturally expanded for n-dimensional data. The method also works well with point-sets that are noisy or not uniformly distributed. We show features and performances of the proposed method via experimental results for various data sets.
