This study attempted to identify the multi-cultural acceptance level of freshmen in nursing colleges and to analyze the factors influencing it. For the research method, data were collected from 410 first-year nursing students at K University in W City through a questionnaire from March 1 to 28, 2021, and frequency, reliability analysis, t-test, ANOVA, correlation, and multiple regression were conducted using the open-source statistical package R. As a result of the study, the multi-cultural acceptance level of freshman in nursing colleges averaged 77.36 points, indicating that they have a slightly higher multi-cultural acceptance capacity, and as a result of analyzing the influence of multi-cultural acceptance related factors, Korean recognition requirements(𝛽=0.34, p<.001), perceived threat recognition for migrants (𝛽=0.29, p<.001), Experience in multi-cultural education(𝛽=0.14, p<.001), Recognition of the appropriate age for multi-cultural education (𝛽=0.20, p<.001) was statistically significant. According to results, it is necessary to develop and actively utilize regular curriculum and programs related to multi-culturalism for nursing students.

The purpose of this study was to investigate the effects of home care hair treatment characteristics and frequency on hair during permanent wave treatment. The hair treatments distributed on the market were classified into cationic surfactants and silicone oil. Hair treatment was performed 5 times, 10 times, 20 times differently according to the frequency of use, and hair permanent wave was performed. The hair thickness, tensile strength, epidermal observation using SEM, and hair component analysis using EDS were performed as experimental methods. The results of the experiment showed that the natural-derived ingredient was the main ingredient, and the cationic surface activity and silicon oil-free product group had high hair protection effect. Therefore, the product group using natural ingredients should be further researched and developed, and the study on the method and frequency of use of products with irritant chemical ingredients should be conducted.

This study aims to verify the potential of functional cosmetic materials by examining the antioxidant effects of Aplidium pliciferum and Herdmania momus, used to determine the antioxidant efficacy of Aplidium pliciferum and Herdmania momus ethanol extracts, Mean and standard deviation were calculated using Minitab® 18 (IBM, USA). After various radicals were removed from the extracts of Aplidium pliciferum and Herdmania momus, DPPH was detected in 30.87±1.98% in Aplidium pliciferum, 88.27±0.84% in Herdmania momus, and ABTS in 56.23±2.50% in Aplidium pliciferum and 94.80±0.91% in Herdmania momus in the concentration of 20 mg/ml. Also, NO was detected in 88.57±0.81% in Aplidium pliciferum and 97.53±0.34% in Herdmania momus, respectively, thus all showing statistically significant differences. So we can confirm the efficiency of the solvent acts as an important factor through the total poly phenol content

The purpose of this descriptive research is to get basic data for educational program after investigating convergent effect of psychological capital on learning satisfaction of nursing freshmen. Using SPSS 21, T-test, ANOVA, Pearson's correlation coefficient and hierarchical multiple regression of the 164 collected data were carried out. The mean scores of psychological capital and learning satisfaction were above the middle, and the 'hope' was the highest among subdomains of psychological capital. There was a positive correlation between psychological capital and learning satisfaction(r=.665, p<.001). School performance(${\beta}=.311$), school life satisfaction(${\beta}=.191$) and psychological capital(${\beta}=.522$) were the significant factors of learning satisfaction in hierarchical multiple regression(F=37.651, p=.004). The explanatory rate of variables on learning satisfaction was 57.4%. It is needed applying these results in developing learning satisfaction programs, but it isn't appropriate to generalize these results conducted on nursing freshmen in one university.

This thesis is about the study of inverter terminal boxes in a explosion proof type exhaust fan that can control wind volume and operating time. In Korea, there is no ventilator to adjust the amount of wind and operating time when working in poor conditions. The purpose of the project is to create a explosion terminal box that can control the operating time and wind speed of a suitable explosion ventilator in hazardous environments. The two explosion-proof switches allow the operation time to be driven 1 hour, 3 hours and continuous time, and the speed of the induction motor rotation was set in 3 stages at 2000 rpm, 2600 rpm and 3000 rpm to control the volume. The tested motor used a half-horsepower barrier three-phase induction motor and a full-bridge inverter to set the desired flow rate and operating time.

The purpose of this study was to examine the difference between communicative competence and problem solving ability by applying project - based instruction in the community dental hygienic subject. For this purpose, we measured 30 students' communication ability and problem solving ability using the same questionnaire before and after experiencing project learning. The data were Collected from 30 undergraduate students and analyzed by paired t-test with SPSS. The result demonstrated that project-based learning method has an significant effect on improvement of communication skill and problem solving ability of undergraduate students. Based on the results of this study, in order to improve the practical ability, it is necessary to activate the self-directed active learning method such as Project-based learning for community dental hygiene major study.

The purpose of this study is to examine the effect of parents' positive and negative parenting attitudes on multicultural expropriation and the mediating effect of community spirit in the process. For this purpose, 1,336 first - year students who entered the university were sampled based on the 7th year data of Korea Youth Policy Institute for a regression analysis. The main results are as follows. First, the positive parenting attitude of the parents recognized by university students has a positive influence on multicultural expropriation, and the negative parenting attitude has a negative influence on multicultural expropriation. Second, Community spirit is found to have a positive influence on multicultural expropriation by university students and shown to have a partial mediated effect between positive or negative parenting and multicultural expropriation. Based on the above research results, various programs were developed and applied to enhance parents' positive parenting attitude and multicultural expropriation, and to promote positive parenting attitude and community spirit.

This study aimed to investigate the effects of motive of use, stress and interpersonal satisfaction on smartphone overdependence in dental hygiene undergraduates. A questionnaire survey was conducted on 216 dental hygiene students in colleges in Dajeon and Chungnam regions. The results showed that motive of use(3-4hours/>4hours)(${\beta}=-0.178$), weekday usage (<3hours/3-4hours)(${\beta}=0.163$), and weekday usage (${\beta}=0.196$) had a high impact on smartphone overdependence in dental hygiene students. Weekday usage dummy 1 was the factor with the greatest impact, with an explanatory power of 25.6%. Additional studies on various factors that affect smartphone overdependence as well as education programs for preventing smartphone overdependence in dental hygiene students are needed.

There has been a large literature on bank liquidity risk since the 2008 global financial crisis because liquidity risk was at the heart of the crisis. However, there is no study that investigates whether the level of investor protection influences liquidity risk-taking behavior of banks. Therefore, this study aims to explore the relationship between investor protection and liquidity risk as well as to provide policy implications. Using a panel dataset of commercial banks in 21 OECD countries, we found that strong investor protection encourages banks to take lower liquidity risk. Furthermore, this positive role of shareholder protection is more prominent during a crisis, implying that legal protection of investors plays an essential role in bank stability while market discipline is largely ineffective due to extensive government guarantees in turbulent times.
