인터넷과 정보통신 기술이 발전함에 따라 영화 유통의 창구도 다양화 되고 있으며, 인터넷 VOD 극장은 저렴한 가격과 인터넷이라는 시간과 공간의 제약성이 없는 특징을 통해 새로운 영화 창구로서 자리 매김 하고 있다. 본 연구에서는 인터넷 VOD 극장을 이용하는 데 있어서 기존 연구에서 나타난 기술수용이론의 지각된 유용성과 몰입이론의 변수 그리고 인터넷 VOD 극장에서 제공하는 영화에 대해 소비자가 느끼는 흘드백 기간에 대한 민감도와 인터넷 VOD 극장에서 제공되는 영화 장르 선택의 다양성이 소비자의 이용 의도에 미치는 영향에 대해 살펴보았다. 본 연구의 의의는 기존 오프라인 영화관 및 다른 영화매체와의 경쟁 속에서 새로운 유통 창구로 자리매김하고 있는 인터넷 VOD 극장의 매체적인 특성을 찾고, 인터넷 VOD 극장 이용자의 이용 의도에 영향을 미치는 요인을 분석함으로써 향후 인터넷 VOD 극장 수익 발전 방향을 모색했다는 점에서 실용적인 의미가 있을 것이다.

The objective of this study is to find the factors influencing the use of mobile service. We extracted critical study variables according to literature reviews about adoption of information systems, those under the internet environment and mobile internet adoption for theoretical foundation. TAM suggested by Davis(1985) has explained the acceptance mechanism with the following constructs: perceived usefulness, perceived ease of use, attitude toward use, behavioral intention and actual usage. After studying prior literature reviews, this study investigated the group of people using mobile services. The result of study claims that it has same results with previous TAM, especially between personal innovativeness and attitude toward use have strong statistical relations. On the other hand, there haven't been any statistical relations between perceived ease of use and perceived usefulness and between perceived usefulness and behavioral intention, either. In conclusion, use of mobile service can be promoted by developing various kinds of mobile service, designing device and interface to use mobile service more convenience and familiar, stimulating user's innovative characters and recognizing mobile service more useful in real life.

The Internet has developed the computer and communications world. The Internet has tons of millions of sites. To find the specific information, we use a search engine. All search engines are operated by keyword against a database, but many different factors affect the result of search by engines. In this paper, we investigate the development of the Internet and try to find the differences among the most popular search engines.

Objectives : Internet addiction or pathologic internet use is one of the major mental health problems in children and adolescents in Korea. Internet addiction is defined as uncontrollable, markedly time-consuming internet use, which lasts for a period of at least six months. Internet addiction results in poor academic performance and negative parent-child relationships. By using $^{18}F$-fluorodeoxyglucose-positron emission tomography (FDG-PET), we investigated the effects of internet addiction on functional changes occurring in the adolescent brain. Methods : Adolescent patients with an internet addiction (4 boys and 2 girls; $15.6{\pm}1.2$ years) participated in this study. Eight healthy young adults (5 males and 3 females; 18-30 years old) with no previous history of psychiatric illness also participated as normal controls. Brain FDG-PET data was obtained with the participants in the resting condition and with no addictive stimuli. Results : Statistic parametric mapping analysis of the brain FDG-PET data revealed hypometabolic changes in the visual information processing circuits and hypermetabolic changes in the prefrontal areas in the adolescents with internet addiction, as compared with normal controls (p<.001). Conclusion : These results suggest a neuronal adaptation to excessive visual stimulation and synaptic plasticity due to internet addiction.

This study was carried out to investigate the utilization status of internet and dietary information by gender (boys : 442, girls : 461) in school children (total 903). The results were summarized as follows. The most of children used internet regularly (98.1%) and major purpose of using were mentioned as 'game (39.0%)' and 'social intercourse (49.5%)'. The duration of internet use was '< 2hours (80.9%)' They used internet mainly at 'home (88.8%)', and favorite search engines were 'Yahoo (54.2%)' and 'Daum (31.1%)'. The searching experience on dietary information was from only 35.6% of subjects mainly 'for homework (39.6%)' and 'for health (36.9%)'. The satisfaction degree of searched information was 'high (79.5%)'. Dissatisfactory reasons of internet site for dietary information were pointed out to be 'bring little interest (28.9)', 'difficult contents (19.2%)', and 'poor Information (18.2%)'. Only fifteen % of subjects had experience of nutrition counseling using internet, and purpose of counseling was mainly 'for homework (51.4%)' and 'for health problem (24.3%)'. The problems for nutritional counseling site were pointed out to be 'difficult answer content (31.7%)', 'insincere answer (28.6%)'and 'poor answer content (25.4%)'. They acquire information of nutrition and health management mainly through 'internet (43.7%)'. 'Growth and nutrition (28.3%)', 'improvement in studying ability (13.8%)', 'right weight control (13.3%)' and 'cooking (12.8%)'were most frequently asked information, They had a preference for 'game (40.5%)', 'animation (29.9%)' and 'quiz (18.1%)'as loaming method tools. The favorite site color was 'green (51.3%)'The results of this study showed that although the internet use was very high, they used internet to search dietary information very seldom. Therefore, the information donor should find out what is the optimal tool, what kind of dietary information was needed for school children.

We build and analyze some types of queueing model to discuss capacity dimensioning of access links of a LAN interworking unit connected to the Internet backbone network. We assume that the IWU has a FIFO buffer to transmit IP packets to the Internet through the backbone. In order to analyze the system, we use a Poisson process and an MMPP process as input traffic models of IP packets and we use a general service time distribution as a service time model. But we use both an exponential service time and a deterministic service time in numerical examples for simple and efficient performance comparisons. As performance measures, we obtain the packet loss probability and the mean packet delay. We present some numerical results to show the effect of arrival rate, buffer size and link capacity on packet loss and mean delay.

Data mining has broad applications that reach beyond scholarly and scientific research and provide internet search engine services that are commonly used forms of Text and Data Mining('TDM') of websites. The exceptions and limitations for data mining provide a competitive advantage in the global race for policy innovation because it permits researchers to conduct computational analysis - TDM on any materials to which they have access. For this purpose, Japan and the EU added limitations on copyright to legalize some TDM research through amendments to copyright law, and the U.S. copyright law has allowed data mining by the fair use provision. On the other hand, there are no explicit exceptions and limitations for data mining under the Korean Copyright Act, and there are no cases considering data mining fair use. We review comparatively exceptions and limitations on copyright which will help to encourage AI-related business by using more data smoothly through the mining process and extracting more valuable information.
