In recent years, a platform providing a Visual Programming development environment capable of 3D editing and interaction editing in an In-VR environment to quickly prototype VR/AR contents for education of VR and AR for general users and children. In the past, VR contents were mostly viewed by users. However, thanks to the rapid development of recent computing technologies, VR contents interacting with users have emerged as a device capable of tracking user behavior in a small size It was able to appear. In addition, because VR is extended to AR and MR, it can be used in all three virtual environments and requires efficient user interface(UI). In this paper, we propose UI based on eye tracking. Eye-tracking-based UI not only reduces the amount of time the user directly manipulates the controller, but also dramatically lowers the time spent on simple operations, while reducing the need for a dedicated controller by allowing multiple types of controllers to be used in combination. The proposed platform can easily create a prototype of their intended VR/AR App(or content) even for users(beginners) who do not have a certain level of knowledge and experience in 3D graphics and software coding, and share it with others. Therefore, this paper proposes a method to use VAL more effectively in a 5G environment.

In the era of ultra high speed information communication technology represented by Smart phone and Tablet PC, the disable and the aged people came to be in a position of so-called 'relatively weak people' in the field of information communication due to inconvenience of use and difference in information acquisition and processing ability. Thus, a survey was conducted on Smart phone accessibility items based on previous studies of the disabled with crippled disorder, brain lesions, myelopathy and muscular disabilities having more inconvenience relatively in their use of smart phone due to upper limb dysfunctions. Especially, people with upper limb dysfunctions with relatively weak grip had big inconvenience in the conditions of uses requiring actions such as grabbing and rotating the devices, and due to the characteristics of touch screen input method of Smart phone, they had big inconvenience due to a lack of a guidance for keyboard in input. As a result of questionnaires by the type of disability, it turned out that severe myelopathy causes the most inconvenience in using smart phone.

The web has become indispensable in all of our daily lives. We communicate, study and get information with others through the web. This behavior also continues in the smart phone environment. The biggest problem is that the small display screen of a smart phone degrades the accuracy in selecting or manipulating content for people with low vision. To compensate for this, voice guidance services that combine touch and voice, such as VoiceOver and Talkback, are currently provided to smart phone devices. However, restrictions arise in GUI, TTS control problems, and content expansion and selection. In addition, unnecessary content is also output by voice, which causes fatigue for low vision people to use. In this study, we propose a mobile web browser interface that selects and enlarges a desired area from web browsers and contents, or outputs it as a voice so that people with low vision can easily use the mobile web browser. In this paper, we propose a context selective focusing function that enables selection for each element of web content. In addition, we intend to develop a mobile voice web browser that can enlarge the selected content or output it by voice.

This study is to analyze whether the use of SNS in politics has any political effects. Most previous studies on political participation by SNS tended to just focus on the participation difference between SNS users and non-users. The test results first show that the development of ICT increases citizens' interest in political information and differentiate the methods of their political participation. Second, we identified SNS users tend to have higher reliability in political information and greater transversion effects by the use of media. Finally, the study verifies SNS is a more effective tool in collective actions such as non-customary rallies and demonstration rather than in customary political participation.

Aging is one of the major tasks that our country should resolve. To deal with aging problems, many countries have introduced various new concepts such as active aging, productive aging, and successful aging, well aging and anti-aging. This study suggests a new concept, digital aging, to tackle aging problems, and we use this concept to explore the new policy and policy areas for aged people. Since this concept is not well defined yet, this article focuses reviewing existing research literature. Instead of focusing the negative aspect of aging, this study investigates how to use the digital technology to build such images that the old man can be continuously learning, active and productive.

Objective: The aim of this study is to identify the domestic and foreign laboratory safety management system and to suggest domestic laboratory safety management policy priority. Background: Various types of accidents are occurred in research laboratories according to a variety of laboratory safety risks. However, there are only lists of incidents without any precise accident analysis. Method: We analyzed statistically the survey on current status of laboratory safety management of universities, research institutes, and industrial research institutions carried out by Ministry of Science, ICT and Future Planning in Korea. We also investigated laboratory safety management systems and safety organization carried out mainly in overseas countries such as USA, Japan, Switzerland and France. In addition, we analyze the UCLA College laboratory explosion occurred in the US in 2010. Results: More than 75 percent of 2015 domestic laboratory accidents were occurred in the field of operation management and chemistry research. Also, approximately 55% of accidents took place due to careless use mechanical instruments & dangerous chemicals. In addition, common difficulties of lab safety act applicable organizations are overlapping and comprehensive application of legal requirements. Conclusion: There is a need for laboratory safety professional organizations. Also, the high frequency of use of hazardous substances in the high-risk, such as the chemical field must be strengthened the laboratory safety management. In addition, it is needed to minimize the problems of the research organizations through close cooperation between related ministries and government support policy such as professional development program. Application: The result of this analysis might help to present a differentiated safety management policy and advanced safety management system in laboratory.

The trade war between the United States and China has been going on for many years, and sanctions against Chinese telecommunications companies in the United States are increasingly tightening. Despite these restrictions, ZTE (Zhongxing), China's leading communication equipment company, is rather expanding its market share in the global 5th generation mobile communication (5G) market. ZTE's growth and competitiveness are based on its unique corporate culture. ZTE places great importance on R&D, has a corporate culture of humility and moderation based on traditional Chinese culture. Besides, it has the placement and use of human resources in the right place. While ZTE strives to implement people-centered management, it makes good use of internal competition. Despite ZTE's global market share and corporate competitiveness, virtually nothing has been studied in Korea. The results of this study are intended to be helpful in enhancing the competitiveness of Korea's ICT industry and companies that want to expand to the world while fostering 5G.

ICT education guidelines revised in 2005 reinforce computer science elements such as algorithm, data structure, and programming covering all schools. It means that goal of computer education is improving problem-solving abilities not using of commercial software. So this paper suggests problem-solving method of maze escape through robots' cooperation in an effort of learning these elements. Problems robots should solve are first-search and role-exchange. First-search problem is that first robot searches maze and send informations about maze to the second robot in real time. Role-exchange problem is that first robot searches maze, but loses its function at any point. At this time second robot takes a role of first robot and performs first robot's missions to the end. To solve these two problems, it goes through four steps; problem analysis, algorithm description, flowchart and programming. Additional effects of our suggestion are chance of cooperation among students and use of queue in data structure. Further researches are use of more generalized mazes, application to real field and a talented curriculum.
