본 논문에서는 웹툰 플랫폼 서비스를 위한 모바일 엣지 컴퓨팅의 구조를 제안한다. 웹툰과 같이 모바일 디바이스에서 실행되는 데이터들을 클라우드 서버로 오프로드하거나 원격 서버로부터 필요한 응용프로그램들을 다운로드 받지 않고, 모바일과 가까운 곳에 캐싱 콘텐츠를 전개함으로써 전송 지연없는 서비스를 보장받으며, 데이터가 발생한 근접 지역에서 데이터 분석 및 처리가 가능하므로 딥러닝을 적용한 새로운 서비스 카테고리로 확장할 수 있음을 제시한다.

We have many difficult problems to efficient development and management of a Web-based education system because of the various requirements of various demanders. A Web-based education system consists of instructors and operation managers of system and learners. Those three factors are the most important e]ements of a Web-based education system and we must consider those elements for design and development. In constructivist approach. acquiring knowledge is made by experiences among each members or elements. So we can say that the constructivist elements of a Web-based education system is learners and instructors, operation managers. In this study, we design and implement a Web-based education system, based on the interactions of extended demanders of Web-based education system in constructivist approach and object oriented modeling. In this study we can improve portability and reduce cost because of platform independence from presented system. And in experiment, we compare and analyse two platform web-based education system a point of effectiveness, cost, convenience.

Recently, as the number of smart devices (such as smart TV or Web based IPTV) increases, the way of digital broadcast contents is changed. This change leads that conventional broadcast media accepts Web platform and its services to provide more quality contents. Based on this change, in education field, education broadcasting also follows the trend. The traditional education broadcasting platforms, which just delivered the lecture in one-way, are utilized the Web technology to make interaction between teacher and student. Current education platforms, however, are insufficient to satisfy users' demands for two-way interactions. This paper proposes a new remote collaborative learning platform which able to provide high interactivity among users. Based on new functional requirements from original use case, the platform provides collaborative contents sharing and collaborative video streaming techniques by utilizing WebRTC (Web Real-Time Communication) technology. The implementation demonstrates the operability of proposed system.

In recent offshore industries, various ambiguous terms have been used without clear definition or classification, causing difficulties in legal, technical, and educational understanding and usage. For an example, the commonly used term of 'Offshore Plant' in Korea is not an universal word technically. There has been no clear technical or legal definition about the 'Offshore Plant' and its classification is also very ambiguous; sometimes it is used to refer offshore oil and gas production platform or it is used to mean offshore renewable power generation plant in some cases. To build a conceptual framework, therefore, this paper suggests a classification of offshore units (1) using internationally agreed terms, (2) agreed with the technical classification used by the ship classification society and (3) being able to include not only the current but also future concepts of offshore units.

The cloud computing are provided various ways for accessing resources and services through collaboration. In this paper, we present a cloud computing model for collaboration in cloud environment. By introducing a model, it is possible to introduce and develop an application required for the database and business services. SaaS model can be applied overall or partially. In particular, business operations need various software. Since cost reduction and applying immediate service are available, it is possible to realize the business environment and high quality service.

This thesis is the study about application development for management obesity and personal health matters systematically based on Android smart phone system. Growing obesity problem for students organized by the lack of a device or program to manage at home has been favored as a serious problem. Currently developed smart phones has come into wide use by portable features and many applications. And to support populations of these features smart phones will be available for obesity management in your home without any equipment using. Accordingly, this paper is the study about application development for management obesity for growing students at home based on the latest smart phone platform Android.

E-learning systems have proliferated in recent years, particularly in the wake of the global COVID-19 pandemic. For kids, there isn't a specific online learning platform available, though. To do this, new conceptual models of training and learning software that are adapted to the abilities and preferences of end users must be created. Young pupils: those in kindergarten, preschool, and elementary school are unique subjects with little research history. From the standpoint of software technology, young students who have never had access to a computer system are regarded as specific users with high expectations for the functionality and interface of the software, social network connectivity, and instantaneous Internet communication. In this study, we suggested creating an electronic learning management system that is web-based and appropriate for primary school pupils. User-centered design is the fundamental technique that was applied in the development of the system that we are proposing. Test findings have demonstrated that students who are using the digital environment for the first time are studying more effectively thanks to the online learning management system.

Technology has been changing the travel experience of visitors. Particularly, augmented reality (AR) is one of the emerging technologies, which widely used in cultural heritage tourism sites. This study is based on a new technology acceptance model and future modified this model to examine the relationship between product beliefs, consumer satisfaction with AR, and destination loyalty in cultural heritage sites. Moreover, this paper examined the role of technology readiness (TR) forming travellers' loyalty of destination with a kind of travel technology--AR. The results show that perceived usefulness and perceived ease of use have significant effects on the satisfaction of AR towards the travellers' loyalty of destination. TR is found to have moderating effects on this model.

With the popularization of online learning, mobile learning and blended learning model, augmented reality technology is increasingly widely applied in the field of education today. This article stresses the necessity of applying augmented reality to education by summarizing the current situation and advantages of augmented reality technology in education. Next, the author proposes a new education system-"AR+E education cloud platform system". Last, the author proposes several inspirations for the design of AR-based education software according to the observation and interview of the behaviors and preferences of the respondents.
