This study analyzed the satisfaction and utilization of the institutional applications used by child-education institutions from a parent's perspective. The research target is a parent who enlisted their children in private kindergarten institution located in Gyeong-gi province and final research outcomes are 443 in total. The difference in satisfaction and utilization have been identified with demographic descriptive statistics, students t-test, and F-test statistics analysis method. First, the result of T-test on the difference in satisfaction and utilization based on parents' employment status shows that statistically significant difference was found in convenience from overall satisfaction, communication from overall utilization and child-parent relationship. Second, the F-test of differences in satisfaction and utilization showed a statistically significant difference in education utilization variables, with all variables in educational background and motivation. In terms of utilization, parents' educational background and overall utilization, and children's age were confirmed to have significant differences in communication, children's relationship, and motivation in basic life. Third, the result of multiple regression analysis shows that all predictors, including ease of use, communication, and satisfaction with educational activities, have a statistically significant impact on utilization standard variables, relative contributions showed the highest level of communication satisfaction. Therefore this paper implicates that institutional applications can maximize educational effectiveness by checking the applicability of active communication and educational activities with parents and actively communicating with parents in early childhood through various educational content applications.

During the development process of mega-project, individual buildings including skyscrapers are built following the master plan. It is not a difficult thing to see the gap of standpoint between the urban planners and architects on the project. This study aims to analyze the difference between architect and urban planner's point of view in evaluating international design competition works which the internationally distinguished honorable design companies(SOM, Jerde Partnership, Studio Daniel Libeskind, Foster+Partners and Asymptote Architecture) submitted as the ideas of Yongsan International Business District Design. Furthermore, we made an attempt to quantify the weight of each factors of urban design by each group. Architect and urban planner's viewpoint were revealed with seven architects and seven urban planners evaluating the international design competition works through AHP(Analytical Hierarchy Process). AHP structure was made of two step hierarchy in terms of Master Plan and Landmark Tower. Eight evaluation criteria were set up such as the concept, land use, transportation, feasibility of Master Plan and the concept, location, functional efficiency and aesthetic beauty of Landmark Tower. Results show that Architect have different point of view from that of urban planner. While the architect's weight of evaluation criteria is on the Landmark Tower(0.505), urban planner's weight is on Master Plan(0.642). Feasibility, the location of Landmark Tower and land-use are very important evaluation criteria to architect and urban planner in common. Functional efficiency of Landmark Tower is in architect's favour and transportation is in urban planner.

The KPI of the four perspectives in BSC need to modify because of the change of management environment. In particular, the KPI of the financial perspective needs to modify necessarily. The KPI of financial perspective has been consisted of short-term measures: net profit current year, operating profit, ROE, ROIC, and EVA. But this financial indicators cannot afford to represent essential corporate sustainability management in the change of management environment. So this study suggests CSV(Creating Shared Value) as an additional KPI of financial perspective. And this study investigates whether CSV represents business performance as the additional KPI in BSC adoption firms. To verify a hypothesis, the sample includes listed firms announcing CSR index publicly between 2005 and 2010. The results of this study are summarized as follows. The high CSV firms is higher on the value relevance of firm in comparison with low CSV firms. Moreover, The firm value of BSC adoption firms is lower than otherwise, but it is insignificant. Limitation of Our study is that we have no choice but to use dummy variable. Because it is a material question as CSV measurement. Nevertheless, contribution of our study is to suggest new KPI of BSC perspective to meet management environment.

Psychological properties of learners have influence on learning behaviors in various ways. The purpose of this study was to examine how the goal orientation of learners affected the learning time distribution method. Regulatory focus and theories of intelligence were measured and manipulated in order to differentiate participants' goal-oriented state. Two variables are known to be key variables influencing learner's goal orientation, inducing the approach-avoidance strategy and mastery-performance oriented attitude. In the experiment, the control focus was divided into two groups based on the inclination test score (regulatory Focus Questionnaire, RFQ), and TOI(theory of intelligence) was temporally induced through manipulation to confirm the interaction between the two variables. Participants were able to determine the order of learning freely by learning a set of Spanish-Korean word pairs and then selecting the items they would like to re-learn. Word pairs consisted of difficult or easy items, and learners could learn the same word many times if they wanted to. In the results, promotion-incremental group showed allocating difficult word-pairs in early time.

If complete coronary artery occlusion occurs due to severer coronary spasm, malignant arrhythmias can lead to death. Therefore, early screening for coronary artery spasm angina is essential. Among the test methods, the drug injection test through coronary angiography is generally performed. Therefore, the purpose of this study was to evaluate the advantages of ergonovine drug test for vasospasitc angina examination during coronary angiography, such as the relationship between the procedure time, contrast medium usage, and radiation exposure effects of coronary angiography. Follow-up data of 142 patients who underwent coronary angiography and variant angina examination from september 2021 to february 2023 were used. As a result of analyzing contrast usage dose and dose area product and air kerma dose and number of imaging series and procedure time, variant angina examination was statistically significantly higher than coronary angiography. (p<0.001) In conclusion, variant angina examination other than coronary artery angiography are radiologically negative. Therefore, we think it is better to avoid excessive inspection. Nevertheless, in the case of the provocation test, the longer the examination time, the higher the fluoroscopy time and the amount of contrast medium used, so it is better to conduct the test as quickly as possible or shorten it.

Gender might be interpreted in different roles and meanings depending on social and cultural backgrounds. Based on the premise that understanding of gender may change the direction of mathematics education, this paper confirmed how gender is interpreted in the preceding study of mathematics education in Korea by applying the literature research method. In particular, predictive model based on empirical perspective and gender schema model based on constructivist perspective. Based on the analysis of gender and research methods in cultural and historical composition models based on historical perspectives and postmodernism models based on postmodernism perspectives, this study analyzed trends in domestic mathematics education. As a result of the analysis, it is confirmed that gender is recognized as a biological difference in domestic mathematics education, and that analysis of gender and related elements of mathematics education is mainly used using statistical analysis techniques. This suggests that various approaches to interpreting gender's role in future mathematics education are needed. The existing mathematics education research on gender is composed in terms of gender differences. Since biology at the time did not explain this difference, however, it should now be based on the concept of gender, which is socially defined gender. Accurate understanding of gender and gender can be the basis for clearer understanding and interpretation of gender-related mathematics research.

CGI not only performed a crucial role to make cinema and animation evolved into digital cinema and digital animation but also CGI, an important visual format, settled realism-centric spectacle image culture in public commercial cinema and animation. The fact that CGI visual format could be structuralized in three different view points is discovered through Iconicity, photorealism, verisimilitude, uncanny valley, hyperrealism, and spectacular realism discourse research which explain image culture. First, a formative viewpoint that comes up in an iconic difference between drawing and photograph. Secondly, a cognitive viewpoint that sees visually perceived naturalness and abnormality as a realistic probability issue. Lastly, a customary viewpoint which is rooted in aesthetic tradition of cinema and animation. After that, the features of CGI which is used in the movie 'jungle book'(2016) were analyzed using the structured visual format. Consequently, this movie has hyper-realistic photographic iconicity on the base of realistic probability. Also, by following image-aesthetic convention which uses overstated and amplified narrative as a visual format, at the same time, the movie also has sufficient image-aesthetic convention in animation by personified animal character.

As the viewpoint of data evolves from business resources to value resources, the focus on the data processing is rapidly shifting from the cartesian (alphanumeric) to the contextual. In response to this trend, the government is actively promoting the utilization of public data by the private sectors. With a focus on the fact that the mainstream of public data users is the crowds, this study, therefore, seeks to identify differences between the members and the crowds from information processing view, followed by presenting directions and main points for the design of data platform. This study is perhaps to be a starting point for finding practical alternatives for creating 'collective intelligence ecosystem' and to be a basis for building a big data base in response to the opening of public data.

The adoption of artificial intelligence technology is continuously increasing in online stores. However, there have been no empirical studies that examine whether each of the artificial intelligence functions affects consumers' continuance intent to shop online. This study aims to understand the effect of the main function of artificial intelligence on the continuance intention of online store via empirical analysis. In particular, we focus on how artificial intelligence as a resource affects the heterogeneity of online stores in terms of resource-based views. We also analyzed the mediating effect of online store's image (product and service) between artificial intelligence (AI) functions and continuance intention. The results suggest that the presence of AI function on online stores positively influence the continuance intention from the resource-based perspective. Furthermore, it was found that AI technology positively affects the image of a product and service. We also found that there was a difference in the way of influencing the intention to use online stores by AI functions.

This research aims to compare and identify the prospective elementary teachers' perspectives on mathematics class. In this aim, we analyzed the comments on the mathematics class by the prospective elementary teachers (senior students and junior students) who are differ in the time of study in the University of Education. As the results of this research, the senior students commented the mathematics class by applying the theories in mathematics education, but the junior students did not. Furthermore, the senior students had the more rigid perspectives on mathematics class and commented in more depth on mathematics class in comparison with the junior students. While, the senior students showed a weak point that they overextended and over-applied the some mathematics education theories in the comments on mathematics class.
