We discovered the fact that the most important factor for judging adults' internet addiction in the K-scale method which was developed by Korea National Information Society Agency (NIA), has composed of 4 categories including 20 items, is tolerance and preoccupation factor from the experiments by using data mining techniques. In this research, we propose a new internet addiction diagnostic method based on the degree of tolerance considering users' non-duty internet activities. From some questionnaire participants, their feedbacks for the K-scale and the proposed diagnostic method were collected, and then we confirmed that the proposed user-centered diagnostic method is effective to find undiscovered addicts due to individuals's intention in the K-scale.

A brain-computer interface (BCI) is a communication system that translates brain activity into commands for computers or other devices. In other words, BCIs create a new communication channel between the brain and an output device by bypassing conventional motor output pathways consisting of nerves and muscles. This is particularly useful for facilitating communication for people suffering from paralysis. Due to the low bit rate, it takes much more time to translate brain activity into commands. Especially it takes much time to input characters by using BCI-based typewriters. In this paper, we propose a brain-operated typewriter which is accelerated by a language prediction model. The proposed system uses three kinds of strategies to improve the entry speed: word completion, next-syllable prediction, and next word prediction. We found that the entry speed of BCI-based typewriter improved about twice as much through our demonstration which utilized the language prediction model.

In the era of the fourth industrial revolution, many production plants are gradually evolving into smart factories that apply information and communication technology to manufacturing, distribution, production, and quality management. The conversion from conventional factories to smart factories has resulted in the automation of production sites using the internet and the internet of things (IoT) technology. Thus, labor-intensive production can easily collect necessary information. However, implementing a smart factory required a significant amount of time, effort, and money. In particular, labor-intensive production industries are not automated, and productivity is determined by human skill. A representative industry of such industries is sewing the industry. In the sewing industry, wherein productivity is determined by the operator's skills. This study suggests that production performance, inventory management and product delivery of the sewing industries can be managed efficiently with existing production method by using smart buttons incorporating IoT functions, without using automated machinery.

With the rapid increase of a population, various problems arise from poor education environment and devalued quality of education. Internet cyber School, a new learning system may be one of the best methods to remedy the situation. We conducted a related questionnaire on the high school in PUSAN city for the study of the cyber learning system. Many high school student agreed that Internet cyber education hour should be matched up with the school hour. They must make a use of the cyber school Service to help the students study by themselves. And we also decide that the implemented service will increase the psychological effect spreading to other teaming fields.

With recent surge of Internet use, many people become concerned with side effects of Internet. Especially Internet addiction has become a significant issue. As Internet users become much younger than before, Internet addiction is salient even among elementary school students. While much research has been conducted on adolescents' addiction, only a little research has been conducted on elementary students' Internet addiction. In addition, it is necessary to use a standardized and reliable evaluation tool that is designed to assess the level of children's and adolescents' Internet addiction. The purpose of this study is to grasp the realities of elementary students' Internet addiction using an evaluation tool developed for elementary and secondary students, and to analyze the factors affecting Internet addiction. A survey was conducted to 1,382 5th and 6th graders selected from nationwide schools. The results of this study shows that 5.5% of the sample students are in the stage of serious addiction, and 12.4% in the stage of early addiction. In addition, the degree of Internet addiction significantly differs by various variables such as demographic factors, the experience of Internet use, family-related traits, and social activities.

Today, the media environment has changed dramatically with the development of Internet transmission technology, computer performance, and various media production technologies. In particular, video content is widely used every day through mobile device or computer connected to the Internet. In addition, the ability to produce video content today is more important than ever, as the use of video content is also increasing in the area of information delivery and communication over the Internet. In this study, it was developed a liberal education curriculum in universities for the production of video content. The developed curriculum was composed of a combination of an online curriculum for theory and an offline curriculum for practicum. In the online curriculum, a 54 DOOR contents were developed to allow students to learn the theoretical knowledge and basic making techniques related to the production of video content. In an offline 15-week practicum curriculum, it covered the practical training contents of video content production that should be acquired every week. This developed liberal education curriculum aims to give non-major students in universities the opportunity to learn the technology of producing video content and to foster the ability to communicate in the media environment by using the video content produced.

With the rapid development in computer hardware and software in recent years, the contents and methods of teaching English have been altered greatly. The use of multimedia and the Internet as a means of language teaching is increasing as information technology accelerates. Using multimedia and the Internet in language teaching allows teachers to have more time to devote to interacting with their students. Above all, it arouses in students the motivation for learning and enables each student to study with the speed commensurate to his/her own ability. Both teachers and students can choose their own style that is most efficient for their classes. When students are efficiently stimulated through visual and auditory materials, they can be more easily motivated to utilize and develop creative techniques by using multimedia and the Internet. Thus, in the information age, it would be desirable to innovate the existing concepts of lineal education and allow more student-centered lessons to more readily expose students to contents and experiences according to their own demands.
