Recently one of the main keywords representing of Korea is O2O The O2O market is an intersection of online commerce and offline commerce. The spread and popularization of smartphones transform payment market environment from online-based(PC) to mobile-based(Smartphone) which enable payment service expanses to on/off-line both markets. Due to this movement, data security is mo vulnerable than online-based payment service but the preference of serviceability, security threat becomes bigger.O2O service expansion is now at the stage of beginning with the limited influence, but could affect to the establishment of on/off line payment system of VAN and PG in the future. However, in the moment, the motivation to destruct the system is still weak. In this research, the possibility of Non-PG mobile payment service was suggested as a new way of mobile payment service by using PG. With suggestion, it could eliminate the issues of payment method beforehand and provide low fee to merchants.

Today, further education of adults in the UK is one of the developing areas of continuing education. The Open University with distance learning, in the process of which innovative forms and methods based on computer and telecommunication technologies are used, is particularly successful in the organization of additional education of the adult population. The advantages of distance learning, multimedia - the latest information technologies, which provide the combination of graphic images, video, sound with the help of modern computer tools, are noted. The basic principles and forms underlying the technologies and forms of work with the elderly are defined. The international experience of implementing "Universities of the Third Age" is summarized. The most widespread approach in adult education in Great Britain is informational. The use of computer technologies motivates a new paradigm in educational methods and strategies, which requires new approaches, forms of learning, and innovative ways of delivering educational materials to adult learners. Information technologies have gained great popularity in such activities as distance learning, online learning, assistance in the education management system, development of programs and virtual textbooks in various subjects, online search for information for the educational process, computer testing of students' knowledge, creation of electronic libraries, formation of a single scientific electronic environment, publication of virtual magazines and newspapers on pedagogical topics, teleconferences, expansion of international cooperation in the field of Internet education. The information technology of synchronous distance learning "online" has gained considerable popularity in the educational process today. A promising direction is the use of multimedia technologies in educational activities to create a design of a virtual computer environment by decoding audiovisual information.

In this paper, the results of previous studies and surveys conducted in this study were compared and analyzed to find out how the actual condition of distance learning being conducted due to COVID-19 is changing. As a result, it was found that the'content-oriented class' is being used the most in the current online class, and teachers are spending a lot of time preparing for class. In addition, it was found that' providing appropriate contents as learning materials' is the first item to be supported for online classes. Therefore, in order to improve online classes in the future, it is needed that learning materials that can be used to create class content should be provided to teachers sufficiently. Also, IT equipment and network expansion and the training of teachers for distance learning should be provided.

The COVID-19 pandemic has significantly changed the landscape of knowledge and information services that public libraries around the world have been providing since modern times. In particular, as social distancing has become routine, the contraction of cultural activities and the shift to online platforms have negatively impacted library visitation and use services, greatly reducing borrowing and reading, use of spaces and facilities, interlibrary loan services, program operations, and outreach services. Therefore, this study investigated and analyzed the current status of services provided by public libraries in Korea and abroad in response to COVID-19, and proposed practical ways to improve and expand services in response to COVID-19 based on the results of a survey of librarians' perceptions. Specifically, these include improving the online reservation system for reading and borrowing services and developing and providing various outreach services, acquiring and expanding electronic resources, expanding online program services (reading, culture, lifelong learning, etc.), strengthening library services for vulnerable populations, providing information portal services related to new infectious diseases, strengthening facilities and space provision services, preparing infectious disease response guidelines, and providing education and training to strengthen librarians' capabilities.

In case of flooding, the underwater flight vehicle (UFV) executes the blowing by blowing ballast tanks off using high pressure air (HPA), while it also uses control planes and a propulsion unit to reduce the overshoot depth caused by a flooding and blowing sequence. However, the conventional whole HPA blow-off method lets the body on the surface after blowing despite slight flooding. This results in the unnecessary mission failure or body exposure. Therefore, it is necessary to keep the body at the near surface by the blowing control while reducing the overshoot depth. To solve this problem, an adaptive blowing control algorithm, which is based on the decomposition method expanding the expert knowledge in depth control and the adaptive method using fuzzy basis function expansion (FBFE), is proposed. To verify the performance of the proposed algorithm, the blowing control of UFV is performed. Simulation results show that the proposed algorithm effectively solves the problems in the UFV blowing control system online.
