The rapid development of information and communication technology has brought about a great change in the global industry. The birth of a smart phone has created many new businesses with a new paradigm that transcends the time and space that can be accessed anytime and anywhere through ubiquity, portability and wireless connection beyond the concept of time and space. A positive network is created with the rapid growth of social network sites, like Kakao, Facebook etc.. In addition to this, Platform Thinking, a social platform based on the service network, is becoming a big axis of the industry. In order to find out the fun factors among the characteristics of the social platforms and to reveal the fun factors according to the functions of the social platform as fun theories, We will clarify the characteristics and the factors affecting them. This is a study on social platform, which is based on SNS, and we want to study emotional fun factor of social platform. In the preliminary study, it was found that consumers enjoy the fun through video and social games on social platforms. In this study, the four fun elements(Hard fun, Easy fun, Serious fun, People fun) of Nicole Lazzaro are applied to the fun emotion that users enjoy through social platforms. As a result of research, it is possible to utilize various functions of social platform and achievement feeling of uploading videos and photos using various functions(hard fun), curiosity to find new information and new friends(easy fun), satisfaction to receive responses such as 'likes' and 'feelings'(serious fun), communication with reply and answer comments(people fun).

Changes in trends and national sentiment are gradually changing funeral culture from burial to cremation. A number of cremation facilities are newly introduced to the funeral facilities and the number of cremation is increasing every year. As the number of visitors to cremation facilities increases, the need for proper guidance systems is also increasing. However, cremation facilities at Funeral Cultural Center are not equipped with automation due to the nature of facilities. Even if it is equipped, the automation is insufficiently applied. In this paper, We suggest a solution of the problem that the ending signal is not generated by the different business process as per each cremation object in the cremation facility adopting the automation system. We would like to design the system which mounts IoT-based automation support module which guides cremation progress on the car using for funeral. The construction of the cremation progress guide automation system will provide precise progress to the mourners, simplify complicated procedures such as wired wireless communication between the managers in the field and the management room, and reduce the burden on the field support personnel. The support system is designed to be lightweight and wireless so that it does not interface with the cremation work.

The optical focus variable lenses have been widely used in consumer electronic devices to capture objects which are located in arbitrary position. These focus variable lenses are achieved by changing the distance between the two or more lenses or are made with electrowetting mechanism, liquid crystal material, or liquid with a pump. These lenses suffer from aberrations due to non-uniformities in the electric field and trouble with liquid evaporation. Another drawback of these focus variable lenses is to need an external mechanism (including actuators outside the optical path). In this paper, we present another type of lens using an electroactive polymer. The purpose of this paper is to describe self-deformable thin lens without any external mechanism. We fabricated an IPMC lens with blur-sharp effect. The IPMC lens is composed of both a thermally imprinted, transparent, and concave-structured Nafion membrane and partially electroless-plated the platinum electrode. By applying a low AC voltage to the IPMC lens, the IPMC deforms upward and downward for itself. As a result, the blur-sharp effect was obtained in the concave-structured Nafion membrane. The proposed method for fabricating blur-sharp effect lens has a large potential to realized very small electro-optics, especially in the field of consumer electronic devices.
