인터넷의 폭발적인 이용으로 인터넷을 통한 정보제공 및 각종 서비스가 활발해져 감에 따라 인터넷 이용의 현황과 인터넷 이용자의 특성 및 그 활용 방법 등을 파악하는 것이 기업이나 조직, 정보 제공자들에게 꼭 필요하다고 판단된다. 본 고에서는 국내와 미국, 영국 등에서 체계적 지속적 또는 단발적으로 이루어진 각종 인터넷 이용자 및 인터넷 서비스 활용 현황들에 대한 조사 결과들을 정리하고 비교 분석해 봄으로써 앞으로 인터넷 서비스의 제공과 이용에 있어서의 방향 설정에 도움을 주고자 한다.

Despite their potential value, the mobile Internet services in the domestic market have not been widely accepted as industry experts have expected. To understand why, this study uses the TAM, Technology Acceptance Model, and explores the factors affecting the usage behavior of the end-users. Based on statistical analysis of survey data, we show that social influence and perceived ease of use affect perceived usefulness, and that self-efficacy and focus significantly influence perceived ease of use. Furthermore, perceived usefulness is shown to play a significant role in explaining actual usage of the mobile Internet services. However, contrary to the hypothesized relationships, service quality, focus, and innovativeness of users turn out to have little impact on the traditional endogenous TAM variables such as perceived usefulness, perceived ease of use, and actual usage behavior. Based on these results, we attempt to provide managerial implications for the domestic mobile Internet service providers and to suggest future research directions in this domain of research.

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.

기술은 다양한 차원에서 잠재적 용도를 가지고 있고, 그것을 둘러싼 사회적 맥락에 의해 끊임없이 변화한다. 따라서 기술이라는 인공물의 내적 논리체계에는 정치적 함의가 투영되어 있다고 할 수 있다. 이것은 인터넷 규제기술에도 동일하게 맥락화 될 수 있는데. 어떠한 기술이 채택되느냐에 따라서 정보통제권 관계는 매우 가변적이다. 본 논문은 인터넷 내용등급제를 사례로 이용자 정보통제권에 정합하는 인터넷 규제기술 구조와 원리 및 그 사회적 함의를 고찰한다

Serial communications such as RS-232C or RS-485 have been used to control and monitor the industrial plants for a long in cooperating with a computer or microprocessor. In recent years a great deal of effort has been made to achieve these control and monitoring through Internet network. This paper proposes a microprocessor system to implement remote control and monitoring system through Internet network. The proposed system uses NE2000 compatible NIC for data link and physical layer to access Internet network The microprocessor employed in the system plays a role of interfacing NE2000 compatible NIC interpreting protocols above link layer, controlling and monitoring industrial plants simultaneously. This paper also shows MMI and experimental results which control and monitor two power plants on the computer monitor with a mouse remotely to verify the proposed.

The purpose of this study was to analyze contents of clothing product evaluation statements in the internet shopping mall and to discover consumers' recognition and evaluation of it. The data were collected from 151 consumers' statements in the four internet apparel shopping malls and a questionnaire was developed to measure consumers' recognition of clothing product evaluation statements. The questionnaire was administrated 272 consumers over 18 years old. The results of this study were as follows; First, The contents of clothing product evaluation statements in the internet shopping blog, were divided into three categories which were product, service and consumer buying decision process. Product category include evaluation of clothing product, description of difference between real product and product on the screen, and advice of uses. Service category include quickness and kindness in delivery, store preference for good service. For consumer buying decision process, motivation of purchasing, perceived risk, expression of satisfaction from good buying and canvassing for purchasing were included. Second, consumer recognized that clothing product evaluation statements has function of furnishing information, confirmation of purchasing decision, risk reduction of internet shopping, and interesting entertainment. Consumers also were dependent on product evaluation statements for making purchasing decision. And it was trusted by consumers. This recognition & evaluation were correlated with consumer's clothing product knowledge, involvement, risk perception of internet shopping, experiences of internet shopping. Managerial implications are provided for internet shopping mall.

The purpose of this study were (1) to analyze the current fashion web-sites on the internet, which were increasing rapidly in number, (2) to find out the users purchase experiences of fashion products at internet shopping malls and satisfaction level on the information provided by the fashion sites. The questionnaire was administered to 332 women & men and data were analyzed by frequency, mean, standard deviation, factor analysis, reliability analysis, ANOVA and t-test. The results of this study were as follows. The factors on the satisfaction of information fashion web-sites categorized as 5 areas: Economy$.$Convenience, Aesthetics $.$Recreation, Variety $.$Interests, Up-to dateness $.$Specialization, and Reliability$.$ Precision. On the factor of Economy$.$Convenience, the users who had more frequent access and who were in their 20’s expressed the higher level satisfaction. On the factor of Aesthetics$.$Recreation, the users who had longer periods of time of use, who had lower level of internet shopping mall involvement, and students appeared to be more satisfied. On the factor of Variety$.$Interests, the users marking higher level of satisfaction were those who had higher frequency of uses, who had shorter period of time of use, who had lower level of internet shopping mall involvement and were students. On the factor of Up-to-dateness$.$Specialization, higher level of satisfaction was shown among the users who had shorter period of time of use, who had higher frequency of uses, who were in their 20’s and who were students. There was no significant differences according to Reliability & Precision factor.

인터넷 상에 산재해 있는 사진이나 비디오 등 시각 미디어 데이터를 효과적으로 검색하는 것은 전자 미술 박물관, 전자상거래, 전자 쇼핑몰 등 여러 응용 분야에서 중요한 일이다. 이러한 분야에서는 단순한 키워드 검색이 아닌 내용 기반 또는 의미 기반의 멀티미디어 검색을 필요로 한다. 인터넷 상의 시각 미디어를 효과적으로 검색하기 위해 제안된 선행 연구에서는 시각 미디어의 메타데이터와 온톨로지를 이용하고 또한 웹서비스를 이용하여 의미 기반의 검색을 수행한다. 본 연구에서는 인터넷 상에서 여러 시각 미디어 제공자와 이 제공자들의 정보를 가지고 있는 하나의 중계자가 존재하는 상황에서 시각 미디어를 효율적으로 검색하기 위한 전 단계로 적합한 서비스 제공자를 찾는 방법을 제안한다. 제안된 방법은 사용자의 질의에 적합한 제공자들과 그 순위를 효율적으로 얻기 위하여 온톨로지의 트리 구조를 이용한다. 온톨로지 트리에서 하위 노드의 크기와 자식 노드의 크기에 기반한 이 방법은 기존의 방법에 비해 효과적으로 제공자들간의 순위를 측정한다. 실험 결과 이 방법이 속도는 비슷하게 유지하면서 정확한 결과를 도출함을 보인다.

End-to-end congestion control mechanism have been critical to the robustness and stability of the Internet. Most of today's Internet traffic is TCP, and we expect this to remain so in the future. TCP/IP is the intermediate transport layer candidate for today's applications. TCP uses an adaptive window-based flow control. The congestion avoidance and control algorithms deployed by TCP aims at using the available network bandwidth. This paper compares different congestion control policies, and proposes the new design mechanism for future public networks

Transmission control protocol(TCP) is protocol used in internet. TCP is seldom transmission error and is protocol based on wire environment. TCP uses 3 way handshake ways, data transmission control through windows size, data transmission control through reception confirmation, sliding window for packet delivery. In this study, designed TCP packet ion module for analyze the TCP segments & correct information about TCP. TCP capture in internet using designed TCP module and analysed TCP segments composition. Through this, could analyze the correct information of protocol in network.
