This study aims to examine the results of start-up policies of the previous government (2013-2017) and the current government (2017-2022). We would like to compare the perceptions of founders on the domestic start-up environment in 2016 and 2021. Based on the data (GETR) that surveyed the perception of the startup environment in 2016, a trend survey was conducted to compare the perception of the start-up environment of founders in 2021. As a result of the study, the founder's perception of the domestic start-up environment changed positively overall, but there was no significant change in the perception of 'tax adequacy', 'easy to recover investment', and 'easy to transfer technology'. In addition, the perception of the start-up environment of livelihood founders was negative compared to opportunity-type start-ups. As such, different results were found for each type of start-up. This study analyzed the difference in perception of the past and present start-up environment from the perspective of founders. In particular, I would like to propose a plan to improve the quality of the domestic start-up environment by seeking support measures for livelihood-type start-ups that have collapsed due to COVID-19.

Due to COVID-19, domestic Duty-free shops have been severely impacted, and with the expansion of the untact market, the proportion of mobile shopping has increased. So far, mobile duty-free shop AR shopping is not active, and related research is scarce. Therefore, we aims to enhance Duty-free Shopping APPs with AR technology by researching the needs of foreign users. First, in the mobile duty-free shop app, the AR shopping interface must be in a prominent position to be open and easy to use. Second, there should be an explanation or help for location and function so that all users can easily recognize the AR shopping interface. Third, when wearing duty-free items in the AR shopping interface or adding them to the storage and shopping cart of interest, the interface must be simple and flexible, making it convenient to use and operate. Fourth, technical improvements must be made to prevent errors. We expect that the research will help develop AR shopping technology and domestic duty-free shop AR shopping technology and revitalize online and offline duty-free shops.

In contrast to the global public's interest in the Korean Wave, which has persisted since the early 2000s, our efforts and knowledge on business studies that combine art and technology are limited. This study utilizes a case study methodology to select and analyze notable examples of the integration of various technologies into the performing arts for the growth of Korean performing arts and the continued growth of the Korean Wave. In particular, cases of performing arts utilizing Metaverse have been presented recently, but there is a lack of consideration from the stakeholders' perspective. This study aims to suggest implications for the revitalization of performing arts through the integration of various technologies through case study analysis from these perspectives.

The tourism industry has a great influence on national economy activation. The development of IT technology has enabled the collection and analysis of personal profile information, location information and activity information based on the characteristics, behavior, purchase propensity and interest of tourists. In order to realize this, the implementation of convergence smart tourism information service platform is completed by developing business model, IoT & Big Data integration management system, big data algorithm development and analysis platform in three stages. The underlying technology of the platform and algorithm needs a process of adopting open source, expanding the service element on the basis of it, and then complementing the problem through the test-bed demonstration test that connects the area. Using this platform, it is possible to develop a smart tourism environment that can provide customized services for each tourist by analyzing various information in an integrated manner. Also, it will be possible to improve the life of tourist destination residents and contribute to regional revitalization and job creation through the creation of smart tourism ecosystem focused on the region.

The purposes of this study were to analyze how effects of parental monitoring, parental affection, inconsistency in parenting attitudes on adolescents' school adjustment and intervention to help adolescents school adjustment. Korea Youth Policy Institute to achieve the research objectives, 'Korea Child Youth Panel Survey'(KCYPS 2010) using data from the First year 1 data were analyzed by Descriptive Statistic, t-Testing, ANOVA and Multiple Regression Analysis. The results of the study are as follows. parenting attitudes were an independent variable having a partially significant effect on middle school students' school adjustment. As a results, The level of parental monitoring and affection are high, the level of middle school students' school adjustment gets higher. On the contrary, the level of parents' inconsistency are high, the level of middle school students' school adjustment gets lower. Therefore, it is necessary to research various options to develop promoting positive parenting attitude in order to increase the level of the middle school student's school adjustment

Recently, as cyber attacks have been activated, many such attacks have come into contact with various media. Research on security engineering and reverse engineering is active, but there is a lack of research that integrates them and applies attack systems through cost effective attack engineering. In this paper, security - enhanced information systems are developed by security engineering and reverse engineering is used to identify vulnerabilities. Using this vulnerability, we compare and analyze lifecycle models that construct or remodel attack system through attack engineering, and specify structure and behavior of each system, and propose more effective modeling. In addition, we extend the existing models and tools to propose graphical attack specification models that specify attack methods and scenarios in terms of models such as functional, static, and dynamic.

The purpose of this study was to explore the possibility of creating barrier-free exhibition-appreciation environment based on the visually impaired person's perspectives. Participants were selected by the purposeful sampling method. Researchers conducted a couple of in-depth interviews with four visually impaired persons. Yin's case study method was employed to analyze qualitative information. The analysis revealed nine sub-themes in two sections: three from 'accessibility within the exhibition room'; and six from 'demand for immersive exhibition environment.' Based on the results, following suggestions were presented: First, we need to provide quality information appropriate for artworks-appreciation; secondly, to ensure the visually impaired people to appreciate the culture and arts without any barrier, we need to extend certification of barrier-free living environment to exhibition-appreciation area. Finally, to facilitate these two tasks we need to encourage the convergence research among science and technology, humanities and society, and culture and arts.

In this paper, we propose a non-intrusive load monitoring(NILM) system which can find the power of each home appliance from the aggregated total power as the activation in the trading market of the distributed resource and the increasing importance of energy management. We transform the amount of appliances' power into a power on-off state by preprocessing. We use LSTM as a model for predicting states based on these data. Accuracy is measured by comparing predicted states with real ones after postprocessing. In this paper, the accuracy is measured with the different number of electronic products, data postprocessing method, and Time step size. When the number of electronic products is 6, the data postprocessing method using the Round function is used, and Time step size is set to 6, the maximum accuracy can be obtained.
