This is a user experience study of factors that should be considered in designing home appliances experience service. Untact services are emerging, but the development of home appliances sector is in early stage. Based on the six factors of Stephen P. Anderson's Creating Pleasurable Interface Model, this study conducted surveys, 1:1 in-depth interviews, and participation observations to measure and analyze user experience. In this study, I compared 4060s and 2030s's user experience in that the untact services raise the digital alienation among middle-senior-aged. As a result, there were significant differences between the two, including the opposite satisfaction in terms of reliable, usable and pleasurable factors. I hope that this study will be of strategic help in designing future home appliance experience services.

The purpose of this study is to find out user preference on personification of the public service robot. Public service robot services in public places is increasing, which is expected to continue to increase. Proper anthropomorphism of robots has positive effect on user experience. On the other hand, when the level of likeness exceeds a certain point, it provokes strangeness and a sense of unease. Therefore, it is necessary to prepare standards for anthropomorphism required for public service robots. In order to find it, a survey and an in-depth interview were conducted. According to the analysis, people prefer verbal interaction with the robot, and the proper age for the voice is in their 20s and 30s. It is recommended that no biological signals appear on the robot and there is a need for personalized services. Through this research, it is expected that it will contribute to design of public service robots that enhance user experience.

The fire incident of KT's Ahyun branch occurred last year indicates that hyper-connected society led by 5G technology would be a dystopia instead of a utopia unless seamless connection of 5G service is well secured. Looking backward on 1999, we could peacefully and happily greet the new millennium by making a great effort to prevent the millennium bugs(Y2K) from causing the catastrophe such as a shut-down of banking system. Likewise, we should make a great effort to keep 5G networks and 5G service continuously working without the disruption of even just a second, which would enable us to avoid facing any catastrophes caused by the disruption of 5G service. As a way to do so, it can be considered that 5G service is designated as universal service because it has the key features of public goods like telephone and high-speed internet services.

This paper is to evaluate the usability of two representative video meeting services currently used by university for research to improve the quality of university remote lecture. questionnaires based on Kano Model were designed and in-depth interviews were conducted to provide qualitative approaches. Screen-sharing functions, the one-dimensional functions was the most important function. and attractive functions had relatively diverse directions. For essential functions, there was a wide gap in quality due to user-specific equipment. The function in which other platforms exist or business-related was not important. Webex reacted negatively to the aging UI, while Zoom responded negatively to the unilateral mute function. In addition, the development direction was presented in five ways as a result of analysis of these results. under Corona-19 situation, I hope this study will lead to continuous research to make stepping stone for remoted educational development.

The purpose of research is to examine mothers with elementary school children in Chungcheong and the convergence effect of recognition of food labeling standards on purchasing behavior. A two-step cluster analysis was performed for group classification according to the purchase behavior of processed foods and the collection was determined by Schwarz's BIC criteria. Three types were determined: "convenience pursuit," "large mart preference," and "high cost reverse purchase". The proportion of college graduates in 'large mart preference' was higher, the proportion of employment mothers in 'high cost reverse purchase' was higher, and the need for food labeling standards was higher in 'large mart preference'. 'Shelf life' was recognized as the most important item. 'Large market preference' scored higher in 'used materials' and 'food additives', 'nutrition labelling'. In order to improve the purchasing behavior of processed foods, above all else, it is necessary to develop customized educational media that can be easily applied to real life.

Over the past two decades suicide terrorism has become an ever-widening phenomenon. When suicide terrorism was first introduced in the Middle East it seemed that this new phenomenon was invincible and that it might change the innate imbalance between terror groups and their rivalry governments. This did not in fact occur. Looking at history of terrorism, it can be seen that suicide attacks are in actuality a very old modus operandi. However, contemporary suicide terrorism differs from such historical tactics, just as the whole phenomenon of terrorism differs from ancient modes of warfare. Modern suicide terrorism is aimed at causing devastating physical damage. through which it inflicts profound fear and anxiety. Its goal is to produce a negative psychological effect on an entire population rather than just the victims of the actual attack. The relatively high number of casualties guaranteed in such attacks, which are usually carried out in crowded areas, ensures full media coverage. Thus, suicide terrorism, ranks with other spectacular modus operandi such as blowing up airplanes in mid air or the use of Weapons of Mass Destruction as a sure means to win maximum effect. For the purposes of this paper a suicide terror attack is defined as a politically motivated violent attack perpetrated by a self-aware individual (or individuals) who actively and purposely causes his own death through blowing himself up along with his chosen target. The perpetrator's ensured death is a precondition for the success of his mission. The greatest potential risk suicide terrorism may pose in future is if terrorists carry out operations combined with other spectacular tactics such as blowing up airplanes or the use of Weapons of Mass Destruction. Such a combination will increase immensely the death toll of a single terror attack and will have a shocking psychological effect on public moral. At this level suicide terrorism would constitute a genuine strategic threat and would probably be confronted as such. This study portrays a general overview of the modern history of suicide terror activity worldwide, focusing on its main characteristics and the various aims and motivations of the terror groups involved. In addition, This study provides an overview what is to be done to prevent such terrorist attacks.

This study is designed for library classification of the tourism. Contents studies are summarized as follows. First, an analysis of the current status of classification and items by a key work 'tourism' in KDC, NDC, DDC, UDC, and LCC which are main library classification tables today indicates that they are too limited to travelling and tourism, tourism policy, and tourist attractions etc. Second, we divided areas studies newly based on the theoretical books in order to extract the classification items of the tourism field, and comparatively analyzed main library classification systems today. We divided basic categories of the classification items into four including tourism general, tourists, tourism attraction, tourism media. Third, a new classification was designed for library classification of the tourism field. Basically, the tourism field was assigned to the main four items and the classification items which were weighted or scattered were adjusted.

Recently in the field of IT, cloud computing technology has been deployed rapidly in the current society because of its flexibility, efficiency and cost savings features. However, cloud computing system has a big problem of vulnerability in security. In order to solve the vulnerability of cloud computing systems security in this study, impact types of virtual machine about the vulnerability were determined and the priorities were determined according to the risk evaluation of virtual machine's vulnerability. For analyzing the vulnerability, risk measurement standards about the vulnerability were defined based on CVSS2.0, which is an open frame work; and the risk measurement was systematized by scoring for relevant vulnerabilities. Vulnerability risk standards are considered to suggest fundamental characteristics of vulnerability and to provide the degree of risks and consequently to be applicable to technical guides to minimize the vulnerability. Additionally, suggested risk standard of vulnerability is meaningful as the study content itself and could be used in technology policy project which is to be conducted in the future.

In recent university classes, consistent effort to improve co-operative interaction and communication between student and professor utilizing SNS(Social Network Service) is being made. This research conducted survey study with 137 pre-teachers in Daejeon & Chungnam area in order to find the relationship between pre-teachers' ego resilience, level of social support and awareness of the instructional outcome in classes that incorporate SNS. According to the result, it has been found that male's class satisfaction is higher than female's class satisfaction, while significant correlations have been found between ego resilience-social support, social support-class satisfaction, social support-semester satisfaction, and class satisfaction-semester satisfaction. Also, ego resilience and social support have significant effect on awareness of the instructional outcome. From these results, a rather close attention towards students' characteristics and their adaptation in class is needed in order to successfully carry out classes that incorporate various new media.
