As interest in the Internet increases, related technologies are also quickly progressing. As smart devices become more widely used, interest is growing in words are missing here like "improving the" or "figuring out how to use the" future Internet to resolve the fundamental issues of transmission quality and security. The future Internet is being studied to improve the limits of existing Internet structures and to reflect new requirements. In particular, research on words are missing here like "finding new forms of" or "applying new forms of" or "studying various types of" or "finding ways to provide more" reliable communication to connect the Internet to various services is in demand. In this paper, we analyze the security threats caused by malicious activities in the future Internet and propose a human behavior analysis-based security service model for malware detection and intrusion prevention to provide more reliable communication. Our proposed service model provides high reliability services by responding to security threats by detecting various malware intrusions and protocol authentications based on human behavior.

The purpose of this study is to provide basic data for prevention of VDT syndrome by confirming VDT syndrome according to the type of computer use. The subjects recruited for the research were 518 students who were in the 4, 5, 6 grades from 5 schools in Seoul. The data were collected during the period from October 8 through October 18, 2004. The results were as follows; 1. The mean value of the VDT syndrome was 1.55 (SD=.52) for the 5th graders. 2. The degrees of VDT syndrome according to the characteristics of the subjects shows higher scores for the 5th and 6th graders, boys, students with more than 4 online friends, students with a low degree of school life satisfaction, and for students with parents who had a negative attitude for their children. 3. The degree of VDT syndrome according to the type of computer use showed higher scores when the students used computers for game more than for study, more than 11 hours in a week, more than 2 hours at one time, not having any rest, in dark places, with the monitor less than 40 an distance from the eyes, sitting with their legs crossed and when the keyboard was in a higher position than their elbows. The internet absorbed group showed higher scores than the unabsorbed group. 4. There was positive correlation between the hours of computer use and VDT syndrome. Also, internet addiction and VDT syndrome had positive correlation. Therefore, each home and society needs to pay consistent attention to correct computer use by their students. Especially, schools will have to educate about computer utilization and VDT syndrome.

본 연구에서는 정보시스템 성공모형과 전자상거래 성공모형을 바탕으로 인터넷뱅킹의 특성과 성공요인을 반영한 인터넷뱅킹 성공모형을 설계하고 구조방정식 모형분석을 이용하여 모형의 유용성을 검증하였다. 구조방정식 모형을 통한 실증분석 결과, 사용의 용이성은 유용성과 사용자 만족, 신뢰에 유의한 영향을 미치는 것으로 나타났으며, 안전성은 신뢰에만 유의한 영향을 미치는 것으로 나타났다. 경제적 효익과 유용성, 신뢰는 사용자 만족에 유의한 영향을 미치는 것으로 나타났으며, 유용성과 사용자 만족은 행위의도에 유의한 영향을 미치는 것으로 나타났다. 인터넷뱅킹 사용이 급격히 증대됨에 따라 인터넷뱅킹의 성공을 위해서는 다른 인터넷뱅킹 사이트보다 더 차별화된 서비스를 제공해야 할뿐만 아니라 안전하고 신뢰할 만한 인터넷뱅킹 사이트를 구축해야 한다. 따라서 인터넷뱅킹 성공을 가져다 줄 수 있는 인터넷뱅킹 성공모형을 통하여 다른 은행보다 훨씬 더 우수한 인터넷뱅킹 서비스를 제공할 수 있는 지속적인 평가와 개선이 이루어져야 할 것이다.

Objectives: The purpose of the study is to investigate the attitude toward medical health information in the dental hygiene students. Methods: The subjects were 370 dental hygiene college students in the metropolitan area. A self-reported questionnaire was completed by 350 students from March 2 to May, 3, 2014. Except 20 incomplete answers, data were analyzed by frequency analysis, t-test, and one-way ANOVA using SPSS 12.0 program. The questionnaire consisted of general characteristics of the subjects, satisfaction of internet use, and attitude toward medical health information. Results: Most of the students had personal computers and they did not receive computer education. The students used internet in the variety of the fields. Satisfaction level was 3.28 by 5 point Likert scale. The attitude toward medical health information was 3.20. They would not use computer if possible, and the score was 3.50 points that was the highest mark. There was no statistically significant difference in medical health information by the general characteristics of the subjects. Conclusions: The attitude toward medical health information was not fully satisfactory in many fields. The curriculum for the dental hygiene must include step-by-step computer course and the computer education must provide the diverse educational opportunities for the students.

The use of sensors and actuators as a form of controlling cyber-physical systems in resource networks has been integrated and referred to as the Internet of Things (IoT). However, the connectivity of many stand-alone IoT systems through the Internet introduces numerous security challenges as sensitive information is prone to be exposed to malicious users. In this paper, IoT based-security issues ontology is proposed to collect, examine, analyze, prepare, acquire and preserve evidence of IoT security issues challenges. Ontology development has consists three main steps, 1) domain, purpose and scope setting, 2) important terms acquisition, classes and class hierarchy conceptualization and 3) instances creation. Ontology congruent to this paper is method that will help to better understanding and defining terms of IoT based-security issue ontology. Our proposed IoT based-security issue ontology resulting from the protégé has a total of 44 classes and 43 subclasses.

Management of internal Internet servers is increasingly becoming an important task. According to meet this requirement, they use service log analysis tools and network monitoring tools. But these are not enough to produce advanced management information considering contents of Internet services. Therefor we propose a system and let it detect Internet server systems existing in internal network and individuate those systems with providing profile. Internet server profile includes system's basic information, network traffic information, and Internet service usage information.

그 동안의 인터넷을 이용한 실용영문독해 수업은 단순히 영어로 된 인터넷 홈 페이지를 찾아 독해하는 방식으로 이루어졌다. 이러한 교육 방법은 인터넷 자료의 방대함, 수업의 수준에 적합하지 않은 어휘사용, 인터넷 자료를 찾기까지의 컴퓨터 활용능력의 요구, 또한 독해 후 토론 및 발표의 방안 부족 등의 여러 가지 문제점을 갖고 있어 효과적인 수업을 진행하기 어려운 것인 현실이었다. 따라서 본 연구에서는 이러한 문제점을 체계적으로 파악하고 이를 해결할 수 있는 시스템을 설계 구현하였다.

인터넷의 광범위한 사용과 더불어 이동성은 컴퓨터 사용자들의 컴퓨팅 환경을 급격하게 변화시키고 있다. 이러한 인터넷 사용환경에서 이동성을 보장하기 위하여 IETF에서는 Mobile IP 프로토콜을 표준화하였다. Mobile IP 사용시 인터넷 사용자는 자신의 홈 네트워크에서 다른 외부 네트워크로 이동하더라도 IP 주소 설정의 변경 없이 자유롭게 인터넷을 사용할 수 있는 장점이 있다. 본 논문에서는 이러한 Mobile IP를 학내망에 도입하기 위하여 그 성능을 평가하기 위한 테스트베드를 구축한다. Mobile IP 프로토콜의 사용이 네트워크 성능에 미칠수 있는 영향을 실험적으로 평가함으로써 학내 망에 직접 설치하여 검증할 때 발생 가능한 부작용을 줄일 수 있을 것으로 예상된다.
