Video-on-demand is an interactive service that provides programs (movie, home shopping, etc.) to users connected to a network. This service will require high bandwidth network and video servers with a large amount of storage capacity. From the viewpoint of system analysis, there are optimization problems to be solved. In this paper, we present a dynamic programming method for allocating the storage for programs being served in a multi-level video-on-demand network. In the optimization of the network resource, we consider the three kinds of costs: installation cost for video servers, program storage cost, and transmission (or communication) cost. The factors related to the costs are investigated. An example is shown to illustrate the proposed method.

Disasters are now becoming commonplace and especially the vulnerable group such as the disabled, the elderly, children and foreigners are in a state of overlapping disasters. In this situation, ATSC 3.0-based UHDTV disaster information service for the visually and hearing impaired has been developing. This study focuses on the demand data collected through in-depth interview with the impaired. The demand analysis data is very important to development process of technology. The results of the interview show that it is essential to link the UHDTV disaster signals with home-network, IoT, wearable devices, and various assistive devices for the impaired (hearing aid, smart light bulbs, warning light, etc.). In outdoor space, UHDTV disaster information must be connected to public display media, digital signage, kiosk, screens in bus or taxi. If communication aids for the visually and hearing impaired are equipped with a function that can transmit and receive disaster information, it will help to minimize disaster damage.

The purpose of this study is to analyze the contents of global citizenship education in the 2015 revision of Home Economics textbook and examine the relevance of global citizenship education in the subject of Home Economics. To this end, the contents of global citizenship education included in the 2015 revision of middle school Home Economics textbook were extracted and analyzed from the viewpoint of the UNESCO Topics and Learning Objectives (TLO), according to the procedure of the concurrent triangulation design. When the frequencies of inclusion of the 9 topics of TLOs were counted, about 54.6% of global citizenship education(GCED) content covered in the 2015 revision of Home Economics textbooks in total was related to the socio-emotional aspects. In particular, TLO 4 (Different levels of identity) showed the highest ratio, followed by TLO 5(Different communities people belong to and how these are connected) and TLO 1 (Local, national and global systems and structures). As a result of categorizing global citizenship education learning topics extracted from Home Economics textbooks of middle school by Home Economics sub-topic area, the child and family(94) area showed the greatest relevance to all learning topics. Food and nutrition(13), clothing(13), housing(15), and consumption (14) showed similar distributions of learning subjects. Child and family area is related to global citizenship education in the topics of adolescent development and its characteristics, family relations, sexual and domestic violences prevention, change in family structures and healthy families, aging society and work-family balance, and life planning and career exploration. The food and nutrition area is related to global citizenship education in the topics of nutrition and eating behavior, and adolescents' food selection and safe cooking. The topic of clothing management and recycling of clothing area, housing culture, residential space utilization, and residential life and safety of housing area, consumer life in adolescence of consumption area were related to the learning subject of global citizenship education. As such, high relations between GCED learning topics and Home Economics learning content elements were found. It is expected that the data of this study will be used as basic data for program development, class improvement, and textbook development with global citizenship education as a content element in Home Economics education.

The purpose of this study is to restore religious education at home. Currently, Korean church education is facing a crisis. First, there is a decrease in the number of children in the church due to the problem of the low fertility rate. Second, the number of young people leaving the church is increasing. As a result, Maneun Church and church schools are being reduced or closed. In order to solve this problem, it is necessary to change from church school-centered education to family-centered faith education. This is because the restoration of faith education is also connected with the restoration of the Korean church in crisis. As an alternative to overcome the current crisis of church education, it is necessary to return to the original form of religious education. In other words, we must return to the way God commanded religious education through parents at home. The most important thing is to overcome and recover from the absence of religious education at home. A Christian home becomes a place of education that fulfills the primary responsibility of religious education for children. God has given his parents the primary authority and responsibility for the religious education of their children. However, amid changes in society and home, the educational function of the home was entrusted to other educational institutions or specialized teachers. Parents of Christian families tend to delegate their children's religious education to church schools by neglecting their educational authority and responsibility. Therefore, the purpose of this study is to reinforce that parents should have a Christian view of faith education and become the main agents of their children's faith education. Parents have the authority, responsibility, and duty as teachers for religious education given by God. The educational authority and responsibility of parents originate from God. God has commanded his parents to bring up their children in faith. Therefore, for parents to become the main agents of their children's religious education, restoration is needed in Christian home education. Therefore, the task of restoring the Christian family as a place of effective Christian education and fulfilling the educational mission of faith that God has given to parents is, first, that parents and the church must recognize the importance of Christian home education anew. Second, parents must have the correct awareness and mission in the Christian view of children. The mission of parents in a Christian home is to teach, train, and admonish their children in the Lord so that they can live with Christian values. Third, the church should actively support home education and form a deep bond between church education and home education.

Network human-robot interface is an important research topic. In home application, users access the robotic system directly via voice, gestures or through the network. Users explore a system by using the services provided by this system and to some extend users are enable to participate in a service as partners. A service may be provided by a robot, a group of robots or robots and other network connected systems (distributed sensors, information systems, etc). All these services are done in the network environment, where uncertainty such as the unstable network connection, the availability of the partners in a service, exists. Moreover, these services are controlled by several users, accessing at different time by different methods. Our research aimed at solving this problem to provide a high available level, flexible coordination system. In this paper, a multi-agent framework is proposed. This framework is validated by using our new concept of slave agents, a responsive multi-agent environment, a virtual directory facilitator (VDF), and a task allocation system using contract net protocol. Our system uses a mixed model between distributed and centralized model. It uses a centralized agent management system (AMS) to control the overall system. However, the partners and users may be distributed agents connected to the center through agent communication or centralized at the AMS container using the slave agents to represent the physical agents. The system is able to determine the task allocation for a group of robot working as a team to provide a service. A number of experiments have been conducted successfully in our lab environment using Issac robot, a PDA for user agent and a wireless network system, operated under our multi agent framework control. The experiments show that this framework works well and provides some advantages to existing systems.

Since emotion, creativity, and imagination has become the source of creating added value, the purpose of this study is to grasp the concept of high concept which has appeared as a major key word of modern culture and analyze the types of emotional expression found in modern fashion. Study methods were focused on literature review and case study. The literature review was conducted by news stories at home and abroad. The examples of case study were collected in fashion collection journals and related Internet web sites with their focus on from 2000 S/S to 2009 F/W to analyze emotional expression found in high concept-reflected fashion. The concept of 'high concept' suggested by Pink, Daniel H. lays on stress on ability to creative emotional value or cultural artistic value hidden behind the functional value, to make stories, and to combine ideas which do not seem to be connected with existing things. As a result of study, The forms of emotional expression found in high concept-reflected fashion included: art collaboration and art inspiration which were expressed through cross-category of culture and art; multi-culture design which expresses a mixture between western fashion and oriental costumes; funology design which expresses efficient value by high technology and fun value through humorous elements; and emotional digital design which can be transformed in function, shape and the use of materials representing light which is effectively used for fashion to represent fantasy or illusion connected with digital technology.

The government mandates gradually zero energy building and Photovoltaic power generation systems installed in buildings are emerging as the most realistic alternative to increase the independence rate of building energy. In this study, we propose a method to reduce the power consumption of households by increasing the PV capacity of balconies and applying the method used the charged electric power stored in batteries after sunset. In order to evaluate the electric power energy savings of the residential BESS, a balcony PV 1.2 kW and a battery pack 2 kWh were installed for 9 houses in 4 apartments in Seoul and Gyeonggi-do. The BESS is charged when the balcony PV is generated electric power, and when solar power generation is finished, it supplies power to the electric appliances connected to the load. As a result of installing the solar PV module 1.2 kW and 2 kWh class BESS for 3 households located in Seoul and Gyeonggi-do, the average electric power consumption saving rate was 40%. The reduction in electricity consumption in the case of zero generation surplus power by maximizing the utilization rate of BESS has been improved to about 53%. Therefore, in order to increase the self-sufficiency rate of electric energy in apartment houses, it is effective to increase the solar photovoltaic capacity of the balcony and apply the residential BESS. In the future, it is believed that the balcony PV and home BESS will play a key role in achieving mandatory zero-energy housing.
