  • Traditionally SCADA is connected only in a limited private network. With new technology and facilities, there are also demands of connecting SCADA though the internet. The internet SCADA facility has brought a lot of advantages in terms of control, data viewing and generation. Aside from connecting SCADA to the internet, there are also operators who want to connect their system wirelessly. This can save budget for communication lines. Along with the advantages it brings, are security issues regarding wireless internet SCADA. In this paper, we discuss internet SCADA, its connection through wireless communication and the security issues surrounding it. To answer the security issues, a symmetric-key encryption for internet SCADA is proposed.

  • 인터넷을 기반으로 한 커뮤니케이션은 폭발적으로 증가해 왔고, 현재는 우리 일상에 자리 잡고 있다. 인터넷 커뮤니케이션은 이전의 커뮤니케이션 방법과는 다른 방식의 소통 방식으로 인식되고 있으며, 이에 대한 많은 연구들이 진행되어 왔다. 인터넷 관련 연구의 가장 중요한 주제 중 하나는 인터넷 기반 커뮤니케이션이 인간관계에 미치는 영향이었다. 인터넷은 경제적, 정치적 이익이 있는 반면, 인간관계, 인간의 삶에는 다소 부정적인 영향이 있을 것이라고 주장되었다. 인터넷의 부정성은 기본적으로 인터넷의 익명성에 기초한다. 인터넷의 익명성으로 인한 인터넷 포르노그라피에 대한 무분별한 노출, 악성댓글, 인터넷 게임중독, 개인정보 유출과 같은 인터넷의 부작용들이 보고되었고, 이러한 현실적 문제들은 인터넷의 부정적인 영향을 주장하는 쪽에 힘을 실어주었다. 하지만 최근에 진행되고 있는 인터넷 관련 연구들은 인터넷의 부정적인 측면 뿐 아니라 인터넷의 긍정적 영향에도 관심을 갖기 시작했다. 인터넷이 사람들의 삶과 인간관계에 부정적인 영향을 준다는 입장에 선 학자들은 인터넷이 현실을 대체한다는 관점에서 인터넷의 부정성을 지적하고 있다. 인터넷이 면대면 대화를 줄이고, 현실을 일정부분 대체하게 하면서 여러 가지 부작용이 나타나고 있다고 주장하고 있다. 그러나 인터넷이 삶에 긍정적인 영향이 있다는 관점에서는 개인의 인터넷 사용동기, 목적을 강조하면서 인터넷 보다는 사용자에 초점을 맞추고 있다. 이 패러다임에 따른 연구들은 인터넷이 인간관계의 물리적 제약들을 해결해줌으로써 인간의 삶, 인간관계 등을 확장해준다고 주장한다. 또한 인터넷의 부정적 특징으로 여겨지는 익명성도 도리어 새로운 만남을 보탬이 될 수도 있다고 주장되고 있다. 인터넷에 대한 두 가지 입장은 각각 자신들의 입장을 지지하는 결과를 도출해 내고 있지만 두 입장의 간격을 쉽사리 줄여지지 않고 있다. 본고는 인터넷에 대한 두 가지 입장을 정리하고, 향후 인터넷이 우리 삶에 미칠 수 있는 영향에 대해 통합적으로 검토하고자 하였다.

  • Objectives : Internet became essential component in these days. This study primarily tried to find out the characteristics of high risk internet users through using the communication scale. Methods : We investigated levels of internet addiction using Internet Addiction Scale in 1,193 high school and middle school students. Participants were divided into 3 groups (high risk user group, potential risk user group, normal user group) according to the results from internet addiction scale. We additionally surveyed characteristics of internet use, and patterns of communication and Communication Scale based on Satir theory in 614 from 1,193 participants. Results : Boys showed higher tendencies for internet addiction than girls in internet addiction scale. There were significant differences in mean computer using time especially during weekends among 3 internet user groups. The distribution of communication types in each internet user group was similar and this finding coincided with previous study results. However high risk user group showed higher scores in each inadequate communication pattern such as placating, blaming, super-reasonable and irrelevant stance. Conclusion : These results suggest that adolescents who use internet in addictive patterns may have more problematic communication styles and these may be associated with poor interpersonal relationships.

  • The aim of this study was to draw some suggestions for Internet Policy by using empirical analyses of key factors in Internet addiction in youths. Internet addiction in youths is perceived as a current and significant issue throughout the world. For the purpose of this study, factors that have influence on the Internet addiction of the youth have been explored and analysed empirically of its hypothetical relationships by using the SEM(structural equation modelling). As a result, a few key factors that suggest a strong relationship to Internet addiction in youths have been drawn: subjects' personality, accessibility to the Internet, psychology and communication factor. Particularly accessibility to the Internet, and specifically the duration of time spent online causes the phenomenon of the Internet addiction. This study shows, however, the subjects' personality and communication factor have the most significant causal relationship to Internet addiction. In other word, the Internet addiction has been changing with the various factors including the factors drawn in this study, which are subjects' personality, accessibility to the Internet, psychology and communication factor. Therefore, Internet addiction should not be merely treated as the isolated problem of the Internet itself; rather it should be understood as various dimensions of society, economy, culture etc. Furthermore, some alternatives to deal with the Internet addiction should be found in various approaches.

  • Recently, new devices have been developed for the Internet of Things concept. The devices commonly use RF (Radio Frequency) based wireless communication. With the increase in the number of devices, the space allocated for the radio frequency band in wireless communication fills rapidly. Visible Light Communication (VLC) is an alternative, secure and economical communication technology that uses light instead of radio frequencies. While Web of Things (WoT) is the adaptation of the experience and knowledge acquired from the web into the internet of things ecosystems. By combining these two technologies, the development of the Visible Light Communication for Web of Things (VLC4WoT) system, which can use VLC and WoT technologies, has been our motivation. In our study, microcontroller control circuit was created for VLC4WoT system. Control of the circuits over the internet was performed. VLC based receiver and transmitter units have been developed for wireless communication. Web based interface was created for control. The test apparatus consisting of four objects with four outputs and a transfer unit was carried out. In this test, communication was achieved successfully. It was presented in the study that VLC can be used in the web of things architecture. In the future, it is envisaged to use this system as a safe and economical system in indoor environments.

  • The use and need of health and nutrition information on the PC communication and internet among university students at Chungbuk area were investigated. The data from 167 students from two different universities were collected and analyzed from March to May, 1998. The results are as follows. 1. Male students were 27.5% and female students were 72.5%. 2. Sixty percent and 74.7% of the students had ever used PC communication and internet, respectively. Higher proportions of male students had experiences in PC communication and internet use than fe male students. The main reasons to use PC communication and internet were 1)to obtain information and knowledge(67.4%) 2)to enjoy(10.5%), 3)to make friends or to talk(5.3%) 3. About 40% of the experienced students of the PC communication of internet obtained health or nutrition information. However, only 25% of the experienced students obtained the nutrition information from the internet. Only 10% of the students agreed that the information from the PC communication and internet was very useful. The reasons not to use the information from the PC communication and internet were 'lack of expertise of the information' and 'long response time'. Many students thought that the information provided through the computer should be improved in terms of variety and applicability to the real situation. 4. Among the 33 topics of the health and nutrition information given on the questionnaire, both male and female students had the greatest interest in stress management. The next topics in which female students had interests were diet for weight control, health problems related to menstration, dietary assessment, and cancer prevention. In male students, dietary assessment, infant nutrition management, hypertention diet were the main interests. On the basis of these results an information system on health and nutrition management during the lifecycle for Korean women will be constructed on the internet.
