Purpose: The purpose of this study was to explore the relationship between cyber leisure activity and autonomic function in high school students. Methods: The subjects of this study were 242 second graders at high school located in D city. The research design was descriptive correlation study. Data were collected from August 26 to September 17, 2010, using a cyber leisure questionnaire and heart rate variability (SA-6000, Medicore, Korea) for autonomic function. Results: Total time for the cyber leisure activity was $391.3{\pm}262.0$ (min/week). Time for internet usage and computer game was $234.5{\pm}140.1$ (min/week) and $156.8{\pm}164.3$ (min/week), respectively. There were significant positive correlation between total cyber leisure time and sympathetic activity (r=.247, $p$ <.001). Conclusion: Excessive cyber leisure activity could increase sympathetic activities in high school students. Thus, nursing intervention to reduce the total cyber leisure time will be helpful to improve their neurophysiological status.

본 연구의 목적은 청소년 측두하악장애 환자의 개인 특성, 신체 활동 및 사이버여가활동과 턱관절증상과의 관계를 알아보기 위한 것이다. 부산대학병원 구강내과에 턱관절증상으로 내원한 11～19세 청소년 219명과 대조군 90명의 개인 특성, 사이버여가활동 및 신체활동과 측두하악장애 증상과의 관계를 조사하여 다음과 같은 결론을 얻었다. 환자군이 대조군에 비해 수면의 질이 더 낮았고, 사이버여가활동시간이 길고, 빈도가 더 잦았다. 환자군에서는 수면시간이 짧을수록 초진 시 느끼는 통증이 심했으며, 스트레스가 높을수록 신체활동이 더 적었고, 측두하악장애 증상이 심해질수록 사이버여가시간이 더 짧았다.

이 연구는 인터넷 중독, 사이버윤리의식, 사이버비행, 자기통제력, 및 운동참여수준의 관계를 분석하는 것에 목적이 있다. 연구의 대상은 비확률 표본추출법 중 편의표본추출법을 이용하여 D시에 소재한 중학교 2곳과 고등학교 2곳에 재학중인 여학생 총 450명을 표집 하였다. 질문 문항의 일괄적인 처리 혹은 무응답, 오기입 등 신뢰성이 떨어진다고 판단되어지는 62부의 설문지를 제외하고 총 388부를 분석에 사용하였다. AMOS 20.0 통계 프로그램을 이용하여 구조방정식모형을 분석한 결과는 다음과 같다. 첫째, 운동참여수준은 자기통제력을 매개로 하여 인터넷 중독에 간접적 영향을 미치는 것으로 나타났다. 둘째, 자기통제력은 인터넷 중독과 사이버윤리의식에 직접적 영향을 가지며, 사이버 비행에는 인터넷 중독을 매개로한 간접적 영향력을 가지는 것으로 나타났다. 셋째, 인터넷 중독은 사이버비행과 사이버윤리의식 모두에 직접적 영향을 미치는 것으로 나타났다.

This study is to explain the importance and the necessity of virtual cyber-tour in a virtual reality environment, and to present a way of its realization as a mean to surmount the fundamental constraints in current tourism, arising mainly from the individual health, cost, leisure time, and the low perception on tourism culture. This virtual cyber-tour using virtual reality technology will not only provide various indirect tour experiences to the existing tour resources, but also develop a new type of tour system, leading to new worlds which have not been accessible to the Public because of various restrictions coming from the current technology, transportation means, and physical limit's of human body.

The Internet and all of its possibilities and applications have changed individuals' lifestyles in relation to socializing, working, and how they spend their leisure time. Social networking sites (SNSs), such as Facebook or Instagram, are ideal settings for interacting with others but, unfortunately, they are also ideal settings for motivated offenders to commit cybercrimes. Thus SNS users may be more vulnerable to cybercrime. The purpose of this study is to investigate the occurrence of cybercrime victimization, specifically cyber-harassment, cyber-impersonation, and hacking. Self-report surveys collected from a sample of 147 respondents were examined using the moderated multiple regression analysis and a logistic regression analysis to determine possible relationships between SNS lifestyle exposure activities and cybercrime victimization. The results indicate moderate support for the application of lifestyle-routine activity theory (LRAT) to cybercrime victimization. Possible educational and managerial implications, as well as suggestions for future research, are discussed.

drone의 활용은 산업, 레저, 인명구조, 전쟁 등 다양한 분야서 활용되고 있다. 군에서도 drone을 활용한 다양한 연구가 병행되고 있으며, 특히 육군 Army TIGER체계에 전력화 되는 다양한 무인체를 활용한 『유·무인복합전투수행방안』에서의 drone 활용은 전투병력의 피해를 최소화하면서 적에게는 최대피해를 발생 가능하게 하는 육군의 미래 전투수행 모습을 실현 가능하게 하는 최대 수단이 될 것으로 판단된다. 하지만 다양한 체계의 전력화가 진행되면서 각각의 체계를 활용한 전투수행방안은 발전 중이나 무인체의 조종자 입장에서의 제한사항을 식별, 해소하기 위한 연구가 부족하여 이를 발전시키기 위해 우크라이나군의 FPV drone 전투 사례를 기반으로 FPV 도입을 통한 원근감 제한사항 극복, 군 drone 전용 주파수 확보에 대해 drone 조종자 입장에서 제언을 하고자 한다.

The purpose of this study is to explore 'Flow Experience' of those studying English speaking and listening in the e-Learning environment. The exploration of flow experience in this study is based on the literature research of Csikszentmihalyi's flow models and other studies. There have been many studies on flow experience focusing on arts, leisure and sports in accordance with Csikszentmihalyi's original theory, however, his flow theory has recently been adapted to the educational field. Nonetheless, it is in the e-learning environment, rather than the face-to-face traditional teaming environment, that there is not enough flow state measurement scale. Therefore, it is important to develop as a stepping stone a flow state scale for those who study English speaking and listening by the cyber-native-speaker on e-Learning environment to improve their satisfaction and achievement.

Amphibious possible, and good fuel economy, so as leisure and transport has increased the use of hovercraft. Fire started in Korea, the prevalence is increasing in demand as the trend has been increasing steadily. In this paper, the hovercraft's forward and backward direction can be controlled in order to free the reverse bucket control system was developed. Control due to development by promoting the flow of air and turn right, turn left and easy to reverse the life-saving and stable at high speed, etc. has made possible the operation of hovercraft. To prove the validity of the proposed controller in Matlab simulation and the actual delivery at the firehouse, built into a model for the demonstration test was performed.
