본 연구목적은 청소년의 인터넷 사용 수준이 구강증상에 미치는 영향을 분석하고자 제14차(2018년) 청소년건강행태온라인조사자료를 이용하여 60,040명을 대상으로 분석하였다. 인터넷 사용 수준이 구강증상에 미치는 영향요인을 로지스틱 회귀분석한 결과 먹을 때 치아 아픔 증상경험, 치아가 쑤시고 욱신거림 증상, 잇몸통증 증상에서는 스트레스가 높은 경우, 일일잇솔질횟수가 없을 경우, 통증의 인지가 높았다. 또한 인터넷 사용시간은 적을수록, 주관적 건강인지, 수면만족도는 높을수록, 흡연, 음주경험이 없을수록 통계적으로 유의하게 낮았다. 결론적으로 청소년의 과도한 인터넷 사용을 완화시키는 보건교육은 적절한 건강행위를 가능하게 할 수 있을 것으로 사료되고 이러한 구강증상을 예방할 수 있는 보건교육프로그램 개발에 도움을 주고자 한다.

Objectives: In this paper, the survey on internet usage patterns of health consumers was conducted and analyzed in order to determine internet health information assessment criteria for providing correct consumer health information on web-sites. Methods: By using a survey questionnaire with 16 questions on general information and 20 questions on internet health information, data were collected from September 16 to 25, 2005 from 476 participants through an internet web site, http://www.hp.go.kr. Frequency analysis, t-test, and multiple regression were used in order to analyze the difference in assessment criteria, factors influencing assessment criteria, factors influencing user satisfaction, etc. Results: General characteristics of the study population were: the persons over age 40 were the smallest age group; women were accounted for 74.2%; and the persons with average income were the largest income group; and the persons with average health status were the largest health group. Most widely used health information were: exercise, disease, and diet, in order. There was significant difference(p=.001) in importance of assessment criteria between the persons in medical institutions and the persons not in medical institutions. There was no significant difference in other assessment criteria. We also found that contents of websites and easy to use were more important factors than elucidation of information providers and information sources including speciality of information in quality assessment criteria of internet health information. Discussion and Conclusion: Results of this paper were compared with the previous studies from the literatures. Contrary to the previous studies in the literature, there was significant difference in importance of assessment criteria between the persons in medical institutions and the persons not in medical institutions. In order to apply the study results to develop health contents for consumer, there is a need for further upgrade the proposed assessment criteria based on expert opinion.

본 연구는 모바일 VOD 서비스 이용자들의 콘텐츠에 있어 유선 인터넷 VOD 콘텐츠와 모바일 VOD 서비스 이용자들간 이용하는 모바일 VOD 콘텐츠 장르선택과 유선 인터넷 VOD 콘텐츠 선택간에 어떠한 차이가 있는지를 비교하였다. 전체적으로 남성이 여성보다 높은 수준의 VOD활용이 나타났으며 활용 유형은 다양한 콘텐츠와 기분전환, 재미, 프로그램 등에 있어서 남성이 여성보다 상대적으로 높은 수준의 VOD 활용하는 것으로 나타났다. 또한 사용횟수가 높을수록 VOD 활용도 높게 나타났으며, 이에 따라 만족도도 높은 수준으로 나타났다. 또한 인터넷 VOD서비스가 모바일 VOD보다 높은 수준인 것으로 나타나 모바일 VOD 개발을 위한 다양한 프로그램 개발은 물론, 공개적이고 쉬운 요금제도 등을 개발해야 할 것으로 나타났다. 그리고 조사 대상자들은 주로 재미 위주의 프로그램을 이용하기 위하여 VOD를 사용하는 것으로 나타나 VOD에 대한 만족을 높이기 위하여 다양한 프로그램 개발이 필요할 것이다.

A method is proposed to reduce excess resources from a virtual machine(VM) while avoiding subsequent migrations for a computer cluster that provides cloud service. The proposed scheme cuts down on the resources of a VM based on the probability that migration may occur after a reduction. First, it finds a VM that can be scaled down by analyzing the history of the resource usage. Then, the migration probability is calculated as a function of the VM resource usage trend and the trend error. Finally, the amount of resources needed to eliminate from an underutilized VM is determined such that the migration probability after the resource reduction is less than or equal to an acceptable migration probability. The acceptable migration probability, to be set by the cloud service provider, is a criterion to assign a weight to the resource reduction either to prevent VM migrations or to enhance VM utilization. The results of simulation show that the proposed scheme lowers migration frequency by 31.6~60.8% depending on the consistency of resource demand while losing VM utilization by 9.1~21.5% compared to other known approaches, such as the static and the prediction-based methods. It is also verified that the proposed scheme extends the elapsed time before the first occurrence of migration after resource reduction 1.1~2.3-fold. In addition, changes in migration frequency and VM utilization are analyzed with varying acceptable migration probabilities and the consistency of resource demand patterns. It is expected that the analysis results can help service providers choose a right value of the acceptable migration probability under various environments having different migration costs and operational costs.

The purpose of this study were to examine the relationship with respect to internet addiction and internet shopping addiction among internet fashion shoppers, and to find if internet addiction had mediating effects on internet shopping addictive buying. 550 females and males who had purchased fashion goods were used for the survey. For data analysis, descriptive statistics and Amos 5.0 were used. As the results, approximately $32.7\%\;and\;3.82\%$ of subjects were revealed as light internet addictive shoppers and heavy internet addictive shoppers. Also, $14.0\%$ of the internet shoppers in this study were found to have internet shopping addictive tendencies. Psychological factors such as self-esteem, impulsiveness, materialism, and compensatory buying were directly related to internet shopping addiction as well as to internet addiction. Internet-related factors such as flow, skill and usage time also were directly related to internet addiction, but not to internet shopping addictive buying. That is, internet addiction had a mediator effect between psychological factors and internet shopping addictive buying. Also, internet shopping variables such as buying frequency and shopping mall visit frequency were related to internet shopping addiction. Finally, internet addiction was directly related to internet shopping addiction.

As the IT industry has developed, the frequency of mobile communication usage has increased sharply. Mobile communication has many advantages such as improving work performance, communication beyond time and local constraints, and rapid and vast amounts of information exchange. However, mobile communication also allows supervisors to give their subordinates work at any time. Thus, mobile communication may also have a negative impact on workers' stress levels during non-work time. This study examined required time, urgent business, personal engagement, and trivial matters as sub-dimensions of mobile communication messages that workers could receive during non-work time. Further, the nature of the relationship between team leaders and members explains how these messages may increase the stress levels of workers. Supervisors should prohibit the use of such mobile communication, and efforts should be made at the enterprise level. Through this research, we aim to explain the dual nature of mobile communication, and understand how to optimize the usage of this innovative technology

새로운 광고매체로서 인터넷은 짧은 역사에도 불구하고 국내·외에서 활발하게 연구되어 로고 있다. 인터넷의 배너광고는 사용자가 단순히 배너광고에서 나타난 메시지를 받아들이는 존재가 아니라, 욕구와 다양한 사용 동기를 가지고 배너광고를 접하고 클릭하여 욕구를 충족하려는 능동적이고, 목적지향적인 미디어 사용자로의 특성을 가지고 있다. 인터넷 광고에도 다양한 형태가 있다. 그중에서도 특히 주류를 이주고 있는 배너광고가 있고 그 외 메일광고가 있다. 배너광고는 타겟지향적인 성격보다도 불특정 다수에게 노출시키는 관계로 인지율이나 관여도 정도에 따라서는 그 효과가 높다. 메일광고의 경우는 이용 빈도와 효과가 높아지고 있다는 연구가 있으며, 소비자들의 라이프 스타일이 변하면서 타겟으로 선정되는 점에서 능동적인 편이다. 배너광고 노출이 인터넷 광고 효과의 수치가 높다고 단정지을 수 없다면 클릭율이 높은 메일광고도 효과적인 인터넷 광고효과 유형으로 수용 가능하리라는 이론적 배경을 찾아보고자한다. 연구를 통해서 인터넷 광고의 효과 과정의 중요한 가이드라인으로 제시 될 수 있으리라 가정한다.
