FinTech has been discussed as an important business area towards technology-driven financial innovation. The term fintech is a combination of finance and technology, which means ICT technology currently associated with all finance areas. The popularity of the fintech industry has significantly increased over time, with full investment and support for numerous startups. Therefore, both academia and practice tried to analyze the trend of the fintech area. Despite the fact, however, previous research has limitations in terms of collecting relevant databases for fintech and identifying proper application areas. In response, this study proposed a new method for analyzing the trend of Fintech fields by expanding Fintech's terminology and using network analysis and topic modeling. A new Fintech terminology list was created and a total of 18,341 patents were collected from USPTO for 10 years. The co-classification analysis and network analysis was conducted to identify the technological trends of patent classification. In addition, topic modeling was conducted to identify the trends of fintech in order to analyze the contents of fintech. This study is expected to help both managers and investors who want to be involved in technology-driven financial services seize new FinTech technology opportunities.

Social class has become a major focus of research in the field of Western psychology due to its critical impact on human life. The Korean scholarship in psychology, however, has paid very little attention to the issue of social class despite the deepening of social stratification in the country; and the concepts and measurement they used were typically borrowed from sociology. In this study, I discussed what social class means and how it should be measured in order to emphasize the importance of the concept and its related issues. To this end, I examined a variety of theoretical backgrounds on the measurement of social class and the concept of socioeconomic status (SES)-a term commonly used as a synonym for social class. This study divided the method of measuring social class into objective social class and subjective social class, and outlined the characteristics of each approach and their main indicators. Finally, I assessed the recent trend in the Korean psychology on social class measurement. Among the 23 studies I have found, 65.2% used the objective social class index; and education was the objective indicator they most frequently employed, followed by income and occupation. Social stratification identity was used in all seven studies that applied subjective social class. And seven different words to describe social class was found. Based on these results, I concluded that there should be a call for more direct research on social class variables. In addition, I suggest that 'social class', instead of socioeconomic status, should be used as a preferred term in the future studies and propose a few notes on how to use the objective indicators and subjective social class measurement.

Recently, English education of educational institutions is gradually invigorated as the importance of English education for preschooler is increasing. Role-play, in particular, is known as an effective way to learn English for children because it promotes children's interest in language and naturally encounters English-speaking culture. Therefore, in this paper, we tried to find out how to effectively use UCC in role-playing for English education for preschoolers. First of all, questionnaires for pre and post-test were conducted for preschoolers. The results are analyzed by SPSS to find out children's understanding of UCC, interest in English, interest in role-playing, and interest in acting. As a result of the analysis, most children knew UCC well and showed strong interest in watching and producing UCC. Also, the more interested in English and role-playing, the more they wanted to show more advanced English and acting through the feedback of the contents they produced. Therefore, even in preschool children's English education, the development of language and acting can be shown by producing UCC through role-playing under the teacher's control and receiving feedback on it. The results of this study are expected to be effectively used when planning English education through role-playing in daycare centers or kindergartens.

In order to revitalize start-ups in the beauty field, this study attempted to derive characteristic patterns of changes in demand and differences in emotions and meaning for 'beauty start-ups' by dividing the period by year from 2019 to 2021 based on exploratory data analysis (EDA). Most of the search terms related to the keyword "beauty start-up" showed more interest in institutions or certificates that can learn beauty skills than professional start-up education, which still does not recognize the importance of start-up education, and as an alternative, it is necessary to develop customized start-up education programs for each major. We establish hypotheses through exploratory data analysis and verify hypotheses by combining traditional corroborative data analysis (CDA). There has never been an exploratory data analysis method for beauty startups, and rather than mentioning the need for formal start-up education, analyzing changes in interest in beauty startups and the requirements of prospective start-ups with exploratory data will help develop customized start-up programs.

The cloud computing paradigm introduced pay-per-use models in which IT services can be created and scaled on-demand. However, service providers are still concerned about the constraints imposed by their physical infrastructures. In order to keep the required QoS and achieve the goal of upholding the SLA, virtualized resources must be efficiently consolidated to maximize system throughput while keeping energy consumption at a minimum. Using ANN, we propose a predictive SLA-aware approach for consolidating virtualized resources in a cloud environment. To maintain the QoS and to establish an optimal trade-off between performance and energy efficiency, the server's utilization threshold dynamically adapts to the physical machine's resource consumption. Furthermore, resource-intensive VMs are prevented from getting underprovisioned by assigning them to hosts that are both capable and reputable. To verify the performance of our proposed approach, we compare it with non-optimized conventional approaches as well as with other previously proposed techniques in a heterogeneous cloud environment setup.

Now, a management plan is being prepared to conserve the landscape and eco-system of Hallasan National Park. A major concern of park managers and residents is the visual impact that activities have of the Mt. Hala landscape. One of the most important aspects of making management decisions is assessing the visual impact of proposed actions accurately enough to judge whether or not those actions are acceptable. Park managers and residents need methods they can use to assess the visual impact of various management actions. The impact of proposed management activities was portrayed by CCG Photomontage techniques and viewers rated sets of color photomontages on a 7 point SD scale. The findings were as follows : the CCG Photomontage is quite practical, vegetation restoration is necessary, and the proposed management actions are feasible. The visual simulation technique and assessment method in this research helps residents visualize and respond to management activities, making residents' participation in the planning process more effective.

As digital Information equipment is new arrival, new paradigm such as 'function exist but form don't' is needed in the field of design. Therefore, the activity of design is focused on the relationship of human and machine against visual form. For that reason, it is involved emotional factor in the relationship and studied on new field, the emotional interlace. The goal of this paper is to suggest the way of emotional interface on searching multimedia data. The main target of paper is effect sound and human's step and the main way of research is visualization after measuring and analyzing numerically similarity level among emotion-words. This paper suggests the theoretical bad(ground such as personal opinion, the character of auditory information and human's step and case studies on the emotion research. The experimental content about sound is fueled from my previous research and the main experimental content about human's step is made with regression-expression to substitute Quantification method 1 for value about stimulation. The realistic prototype to apply the research result will is suggested on the next research after studying the search environment.
