Purpose: The objective of this study is to investigate the relationship between middle and high school students' internet addiction, social support, self-efficacy and school life adjustment. Data were collected by self-administered questionnaires at middle and high school students located in Seoul and the metropolitan areas. Methods: The response rate is 94.8% (474 cases). The internet addition was measured by K Scale. The various methods of analysis were used, for example, frequency analysis, t-test, analysis of variance, and multiple regression analysis. Results: First, the mean score of internet addiction level is 2.07 in 5 Likert scale. the internet addiction level of the male students are higher than female students (p<.05). Second, as a result of classification of internet addiction groups by K Scale, 11 students (2.3%) are included in high risk group, 27 students (5.7%) are in potential risk group, 436 students (92.0%) are in general group. Third, the level of social support and self-efficacy of middle and high school students are very high. The difference of social support by internet addiction groups was not statistically significant. But, the difference of self-efficacy by internet addiction groups was statistically significant. The level of self-efficacy of the students in general groups are more higher than in high risk group and in potential risk group (p<.01). Fourth, the difference of school adjustment by internet addiction groups was very statistically significant. The level of school life adjustment of the students in general groups are more higher than in high risk group and in potential risk group (p<.01). Fifth, the internet addiction have a negative correlation with school life adjustment. And the social support and self-efficacy have a positive correlation with school life adjustment (p<.01). Finally, in stepwise multiple regression analysis, the internet addiction affects negatively on the school adjustment. And the support of teacher among three types of them affects positively on the school life adjustment.

Purpose The purpose of this study is to deduct the factors for explaining the economic behavior of an Internet user who provides personal information notwithstanding the concern about an invasion of privacy based on the Information Privacy Calculus Theory and Communication Privacy Management Theory. Design/methodology/approach This study made a design of the research model by integrating the factors deducted from the computation theory of information privacy with the factors deducted from the management theory of communication privacy on the basis of the Dual-Process Theory. In addition, this study, did empirical analysis of the path difference between groups by dividing Internet users into a group having experience in personal information spill and another group having no experience. Findings According to the empirical analysis result, this study confirmed that the Privacy Concern about forms through the Perceived Privacy Risk derived from the Disposition to value Privacy. In addition, this study confirmed that the behavior of an Internet user involved in personal information offering occurs due to the Perceived Benefits contradicting the Privacy Concern.

본 논문은 급증하는 인터넷 트래픽예측을 위해 빅데이터와 인공지능기술을 이용하였다. 기존에 트래픽 예측에 관해 다양한 연구가 있었지만 최근 스마트폰이나 스트리밍 등 거대한 인터넷 트래픽을 유발하는 증가 요소를 반영하지는 못했다. 더불어 대용량 인기 게임 출시나 OTT(Over the Top)사업자의 신규 컨텐츠 제공과 같은 이벤트성 요소는 사전 예측이 더욱 어렵다. 이러한 특성으로 기존 방법으로는 ISP(Internet Service Provider)가 실시간적 서비스 품질관리나 트래픽 예측치를 네트워크 사업환경에 반영하기가 불가능하였다. 따라서 본 연구에서는 이러한 문제점을 해결하고자 기존 NMS와는 별개로 트래픽 데이터를 실시간적으로 탐색, 판별하여 수집하는 인터넷 트래픽 수집시스템을 구축하였다. 이를 통해 수집대상의 데이터를 자동등록할 수 있는 유연성과 탄력성을 확보하였으며 실시간 네트워크 품질모니터링을 가능하게 하였다. 또한 시스템에서 수집된 대량의 트래픽 데이터를 머신러닝(AI)으로 분석하여 OTT 사업자의 미래 트래픽을 예측하였다. 이를 통해 보다 과학적이고 체계적인 예측이 가능해졌으며 더불어 ISP 사업자 간의 연동 최적화와 대형 OTT 서비스의 품질확보가 가능할 수 있게 되었다.

Information and Communication Technologies(ICTs) have substantially enlarged both the opportunities to realize one's human rights but have also resulted in the emergence of new challenges. ICTs are so deeply embedded and cental to almost all aspects of human activity. And ICTs are assuming an increasingly central role in all aspects of human and societal development across the world. But this is especially true of the right to privacy, which faces challenges such as profiling and data mining for public(including national security) and private purposes. ICTs access is a fundamental right for all humans in the information age. So we have need for regulation based on human rights in the digital age. And governments have a responsibility to protect individuals against violations of human rights and data protection by public authorities, but also by private entities. In addition, internet governance and multi-stakeholder principle have to be stressed on all of the internet issues because internet governance is included in the principle of democracy which have bottom-up communication and equality. So it is very importance that Internet Governance Forum is the space for a meaningful discussion on public policy issues relating to the internet.

인터넷에 관련된 알고리즘이나 정책에 관한 연구는 대형 네트워크 상에서 실험을 해야 하지만 현실적인 어려움 때문에 네트워크 위상 모델을 많이 사용하고 있다. 이런 면에서 정확하게 인터넷의 특성을 반영하는 네트워크 위상 모델에 대한 연구는 매우 중요하다. 이러한 위상 모델을 생성하는 방법에 관한 기존 연구는 인터넷의 특성을 파악하고 이를 잘 반영하기 위한 여러 가지 방법을 제안하고 있다. 그러나 인터넷이 시간에 따라 변화하는 특성에 대해서는 충분히 연구가 이루어지지 않고 있다. 따라서 본 논문에서는 시간이 경과함에 따라 노드가 생성되고 소멸되며 이에 따라 위상이 변화하는 현상을 모델링하기 위한 알고리즘들을 제안한다. 제안된 알고리즘에 의해 생성된 위상을 분석한 결과 기존 방식에 비해 power-law를 더 잘 만족함을 확인하였다. 이 알고리즘은 미래의 인터넷 위상을 예측하는데 도움이 될 것으로 생각된다.

In this study, there are two research objectives. First, we identified the impact of service quality on customer satisfaction and intention to repurchase in the Internet shopping mall. Second, we tried to analyze the mediating effects of the customer satisfaction on the relationship between service quality and intention to repurchase. Based on past research and theoretical discussions, we developed a research model in terms of service quality and intention to repurchase in the Internet shopping mall. In order to verify our research model, we analyzed 492 survey data of consumers who had experiences in the Internet shopping mall in China. We found that sub-factors of the service quality in the Internet shopping mall have positive effects on customer satisfaction and repurchase intention through the survey data analysis. Among the five factors of service quality in the Internet shopping mall, except assurance, the positive effects of tangibility, responsiveness, empathy and reliability on repurchase intention are statistically significant. In addition, we found mediating effects of customer satisfaction in the Internet shopping mall on the relationship between service quality and intention to repurchase.
