Estimation on SW Sizing applied to fintech is very difficult, a task requiring long time, it is difficult for client companies and developer companies to accurately calculate the size of software development. The size is generally estimated based on the experience of project managers and the general functional scoring method. In this paper, propose a model that can be applied to fintech development projects by quantitatively calculating the required functions from the user's point of view, measuring the scale, and calculating the scale in real time. Through the proposed model, the amount of work can be estimated prior to development and the size can be measured, and the M/M and the estimated quotation amount can be calculated based on the program list by each layer. In future studies, by securing size computation data on existing the Fintech Project in mass, research on accurate size computation would be required.

The author tried to verify the mediating effect of the variable, perceived behavioral control, in the relationship between the independent variables(cosmetics-related variables, consumer's preference, advice & inducement), and the dependent variable(purchasing behavior), through AMOS structural equation modeling. As a result of analyzing the mediating effect in the impact relationship between latent variables, it was found that PBC(perceived behavior control) plays a mediating role in the impact relationship between CQ(cosmetics quality) and PB(purchasing behavior). Author found that the higher the quality of cosmetics and the greater the perceived behavior control in domestic cosmetics purchasing behavior, the more likely it will lead to purchasing behavior. In this context, while efforts are being made to improve cosmetic quality, measures to increase perceived behavior control, which can be said to be autonomy in purchasing behavior, should be sought.

The purpose of this study was to determine the effect of sedentary time on quality of life and oral health-related behaviors using the Korean National Health and Nutrition Examination Survey. A total of 19,983 data were analyzed using the IBM SPSS 25.0 program, and complex sample logistic regression analysis was performed to confirm the effect of sedentary time on health-related quality of life and oral health-related behaviors. As a result, the longer the sitting time, the worse the quality of life (p<.05). There was an increase in the number of cases of not brushing (p<.05). Also, as for dental treatment, the longer the sitting time, the more prophylactic treatment and periodontal treatment increased (p<.05). Therefore, it is judged that it can be used as basic data to improve the quality of life and increase oral health-related behaviors in consideration of the socio-demographic characteristics of prolonged sedentary time.

In this study, the antioxidant activity and anti-inflammatory activity of Lindera obtusiloba flower fermentation extracts were identified. To evulate antioxidant activity and antioxidant concentration, polyphenol concentration measurements, flavonoid concentrations measurements, DPPH experiments, and ABTS experiments were conducted. In Flavonoids, DPPH and ABTS assay, antioxidant activity were increased after fermentation. At this time, the flavonoid concentration was 5.0%, the DPPH experiment showed 33.27% and the ABTS experiment showed 29.82% antioxidant increase. In the anti-inflammatory experiment, we conducted a cytotoxicity experiment and an anti-inflammatory experiment for LPS-induced inflammation. Cytotoxicity showed low cytotoxicity in both control and fermentation groups, but lower cytotoxicity in fermentation groups. In the case of NO production inhibition, fermented Lindera obtusiloba flowers showed an increase in anti-inflammatory activity by more than 50% compared to the control group, showing that they can be used as a cosmetic ingredient with anti-inflammatory function.

This is descriptive research aimed at determining the relations with appearance satisfaction and self-efficacy in controlling job-seeking stress and at providing basic data necessary to decide on an education direction for better career maturity and explore psychological resources. For data collection, convenience sampling was performed among dental hygiene students consenting to participate in the research in Chungcheong and Jeolla Provinces to complete a self-administered questionnaire from November 25 to December 13, 2019. Appearance satisfaction was positively correlated with self-efficacy and was negatively correlated with job-seeking stress; self-efficacy was negatively correlated with job-seeking stress. The factors affecting job-seeking stress were self-efficacy, appearance satisfaction, and major satisfaction. It would be necessary to develop a practical counseling program targeting the combination of positive appearance acceptance and improvement in self-efficacy on the basis of correct aesthetic values with the objective of reinforcing job-seeking competence intensively among dental hygiene majors.

The purpose of this study is to examine the sequential mediating effects of social withdrawal and depression in the relationship between achievement motivation and career decision of multicultural adolescents. To this end, we analyzed adolescents data from the 8th year survey(2018) of the 'Multicultural Adolescent Panel Study(MAPS)' provided by the National Youth Policy Institute(NYPI). As a result of the study, first, achievement motivation was found to have a significant and positive effect on career decision. Second, it was found that social withdrawal did not mediate the relationship between achievement motivation and career decision. Third, it was found that depression mediates the relationship between achievement motivation and career decision. Fourth, it was found that social withdrawal and depression sequentially mediate the relationship between achievement motivation and career decision. Based on the results of this study, we searched for social support measures to improve the career decision of multicultural adolescents and support their career paths, and suggested implications and limitations of the results of this study and suggestions for follow-up studies.

This study aimed to identify the impact of human rights violations on elderly discrimination, focusing on the mediating effect of elderly-related experiences. After conducting a two-month survey of 143 dental students in some parts of Busan from September 4, 2020, hierarchical regression analysis was conducted to find out the mediating effects of elderly-related experiences using the SPSS 26.0 program. Dental hygiene students' perception of infringement on elderly human rights was shown to be significant in elderly discrimination(r=-.310) and elderly-related experiences(.185), indicating that elderly-related experiences were partially mediated in elderly human rights infringement and elderly discrimination. Therefore, this study intends to provide basic data on the development of dental hygiene curriculum in a super-aging society by reconsidering the need for senior-related experiences in dental hygiene and education.
