The purpose of this study was to identify the effect of skin care salons' decision factors on customer satisfaction and revisit intention during the COVID-19 pandemic. The subjects of this study were 220 women in their 20s to 50s who reside in Seoul and the Gyeonggi-do area and are users of skin care salons. The data was statistically analyzed using SPSS V.25.0 and detailed research results are as follows. For the analysis of this study, frequency analysis, factor analysis, reliability verification, independent sample T-Test, one-way analysis of variance, post hoc test, Duncan test, and regression analysis were conducted. First, as a result of examining whether skin care salon decision factors during the pandemic have a positive (+) effect on customer satisfaction, hygienic environment satisfaction and service environment satisfaction, which are sub-factors of customer satisfaction, had a significant effect on professionalism, kind service, and distance, which are sub-factors of decision factors, and are independent variables. Second, as a result of examining whether skin care salon decision factors during the pandemic have a positive (+) effect on revisit intention, decision factors, which are independent variables, including professionalism, kind service, price, and distance showed significant effects on human revisit intention, As for physical revisiting intention, only kind service, distance, and professionalism showed significant effects, while price did not have a significant effect. Third, as a result of examining whether customer satisfaction during the pandemic has a positive (+) effect on revisiting intention, the service environment satisfaction and hygienic environment satisfaction, which were sub-factors of independent variables, showed significant results for human and physical revisit intentions. In this study, service environment and hygienic environment satisfaction were important variables for skin care salon decision factors. Professionalism and kind service were important for human revisit intention. Therefore, overall service environment, hygiene, and safety should be prioritized to increase revisit intention and efforts must be made to retain and improve customer satisfaction

This study examined the effects of entrepreneurship and perception of entrepreneurial environment on business performance. In particular, this study analyzed the difference in the effect of each independent variable on the dependent variable by using the government's participation in the start-up support project as a moderate variable. In order to achieve the purpose of this study, the researcher drew the variables corresponding to entrepreneurship and the variables related to entrepreneurship awareness. Innovativeness and risk sensitivity were selected as variables for entrepreneurship, and market environment and product environment were selected as variables for perception of entrepreneurial environment. Based on the above variables the research model was completed including the degree of participation in the government's start-up support project as a moderating variable. The data for the empirical analysis were collected from start-up companies in Daegu in 2018. A total of 601 questionnaires were collected and 399 copies of the data were used in this study after removing the unfaithful answers. The results of the analysis showed that innovation had a negative effect on management performance, and risk sensitivity, market environment, and product environment had a positive effect on management performance. In terms of the moderating effect, in the case of innovation, the higher the participation in government support projects, the lesser the negative effect. Risk sensitivity and product environment showed a strong impact on companies with a lot of government support projects, and the market environment had a strong impact on those who participated less. This study confirmed the importance and necessity of entrepreneurship and perception of entrepreneurial environment that influence the management performance of entrepreneurs. It is also meaningful in that it deals with the practical effects of the government's start-up support project on the start-up performance.

The purpose of this study is to investigate the influence of family-friendly life environment factors including local community's living environment satisfaction (safety, convenience, comfort, accessibility, exchange of neighbor satisfaction), family support facility satisfaction, family support program satisfaction and nurture and education environment satisfaction, and local community's living information accessibility on the effect of multiple roles of married men and women with children. Data were collected from 380 married men and women with children located Seoul, GyeongGi-Do, ChungCheongBuk-Do, and KyungSangNam-Do. The results show that, first of all, related to general trend of role satisfaction and role strain, the subjects have higher experience of role satisfaction than role strain. Secondly, the variables of social demography, such as monthly income, non-regular full-time working system, white collar occupation, number of children and level of education, and living environment variables, such as satisfaction of living environment stability and satisfaction of neighbor exchange in living environment were significantly related to role strain. Thirdly, social demography variables, such as average monthly earnings, gender (male), non-regular part-time working system, satisfaction of stability in living environment, and satisfaction of convenience in living environment were significantly related to role strain.

Climate change causes fluctuations in water quality in the aquatic environment, which can cause changes in water circulation patterns and severe adverse effects on aquatic ecosystems in the future. Therefore, research is needed to predict and respond to water quality changes caused by climate change in advance. In this study, we tried to predict the dissolved oxygen (DO), chlorophyll-a, and turbidity of the Paldang reservoir for about two weeks using long short-term memory (LSTM) and gated recurrent units (GRU), which are deep learning algorithms based on recurrent neural networks. The model was built based on real-time water quality data and meteorological data. The observation period was set from July to September in the summer of 2021 (Period 1) and from March to May in the spring of 2022 (Period 2). We tried to select an algorithm with optimal predictive power for each water quality parameter. In addition, to improve the predictive power of the model, an important variable extraction technique using random forest was used to select only the important variables as input variables. In both Periods 1 and 2, the predictive power after extracting important variables was further improved. Except for DO in Period 2, GRU was selected as the best model in all water quality parameters. This methodology can be useful for preventive water quality management by identifying the variability of water quality in advance and predicting water quality in a short period.

This study aimed to analyze the relative influence of related variables on the university students' civic consciousness. The study sorted out the data for 1,200 university students from a larger data set collected by Son et al.(2009), and analyzed the data by a hierarchical regression analysis method. The study showed the major results in four aspects. First, personal characteristics and home environment variables had mostly no influence on the students' civic consciousness. Second, on the sub categories of the students' civic consciousness, almost no influence was found in case of the home environment variables on democratic constitution and participation-practice, and in case of the school environment variables on value and attitude. Third, among the home and school variables, parents' attitude(${\beta}$=.228) and professors(${\beta}$=.162) had positive influences on the students' civic consciousness. The results suggest that parents and professors should be the two principal axises in the cultivating process of the students' civic consciousness. Third, on the democratic participation and practice no positive influences were found in any of the social environment variables. Among the social environment variables, politicians(${\beta}$=-.238) and corporations(${\beta}$=-.097) had rather negative influences on the democratic participation and practice. These results raised the question on how school education and social political systems are operated in the democratic manners. Fourth, the study recommends that local government would establish the civic education centers, develop various civic education programs, and provide each school with the programs. The study also recommends that each university would democratize in all the school affairs, and actively implement the civic education for university students as a specialized project.

This article involves architecting prototype-fuzzy expert system for designing the nominal cover thickness by means of fuzzy inference for quantitatively representing the environment affecting factor to reinforced concrete in chloride-induced corrosion environment. In this work, nominal cover thickness to reinforcement in concrete was determined by the sum of minimum cover thickness and tolerance to that defined from skill level, constructability and the significance of member. Several variables defining the quality of concrete and environment affecting factor (EAF) including relative humidity, temperature, cyclic wet and dry, and the distance from coast were treated as fuzzy variables. To qualify EAF the environment conditions of cycle degree of wet-dry, relative humidity, distance from coast and temperature were used as input variables. To determine the nominal cover thickness a qualified EAF, concrete grade, and water-cement ratio were used. The membership functions of each fuzzy variable were generated from the engineering knowledge and intuition based on some references as well as some international codes of practice.

As a part of advanced technology society, South Korean youth have been accessing the Internet at a very high pace. The Internet overuse could yield addiction where may be a serious psychological disorder of this century. The literature remarks that gender could make a significant difference on internet addiction. Therefore, this study aims to examine the effect of gender variable on internet addiction for a sample of South Korean university students (n = 815; 312 females and 503 males). The instrument had two sections; the demographics and twenty Internet Addiction survey items based on a five level scale; "Rarely, Occasionally, Frequently, Often and Always". The results showed that general tendency among the participants appeared between "Occasionally" and "Frequently" for internet addiction. In order to test five derived study hypotheses, the researchers conducted comparative statistical tests. The t-tests revealed that gender made statistically significant differences on nineteen items where males were higher than females showing that males significantly spend more time on the Internet than females. Additionally, t-tests results showed that seventeen of the survey items showed statistically significant differences with respect to types of technology dominant environment. The researchers created two dummy variables to combine gender and technology dominant environment variables and gender and school year variables, to have a better understanding the gender effect with one-way ANOVA. The gender difference still exists following its merge to technology dominant environment showing that the gender surpasses IT related environment. When school year combines to gender, males show higher scores for certain items, especially for freshman year.
