This study aims to identify existing legal limitations on tattooing for beauty purposes and to suggest legalization of tattooing for beautician and necessity of institutionalization for the professional qualification system. The results of depth interviews from 10 experts in the field of beauty and law and survey from 101 respondents who experienced with tattooing are as follows. First, 10 experts pointed out that the law does not reflect reality considering the fact that a number of procedures are made illegal, and suggested opinions of the introduction of the professional qualification system. Second, only 15.7 percent of procedures had been conducted by a doctor, and non-medical practitioners showed higher quality of procedure, satisfaction, and recommendation. Side effects do not differ between groups, and 73.7% of the respondents answered that the qualification system is necessary. This study empirically supports the need for improvement in government policies that reflect social awareness of tattooing for beauty purposes.

In the age of oil exhaustion, low cost, semi-transparent solar cell, the dye-sensitized solar cell (DSC) has attracted significant attention since 1991 of $Gr{\ddot{a}}tzel$ report. To enhance the light-harvest capability of the photoelectric electrode, and efficiency of photoelectric transformation of the DSC, scattering layer of various structure have been proposed to photoelectric electrode materials. The scattering center of scattering layer needs the large titanium dioxide nanoparticles of 250 - 300 nm in diameter. In this study, the large sized $TiO_2$ nanocyrstals of around 300 nm were synthesized using the modified sol-gel process. According to the analysis of XRD and TEM, the synthesized $TiO_2$ nanoparticles exhibit single crystals of anatase phase. The optical transmittance of the synthesized titanium dioxide film prepared by spin coating is around 50% at 550 nm. It is suitable for scattering layer as a scattering center, and expected to enhance the efficiency of photoelectric transformation of the DSC.

The purpose of this study was to find out a correlation about the knowledge of blood donation, attitude and altruism to nursing students, to use as basic data that can contribute the ways to promote active blood donation practice of nursing college students. Data were collected from 133 nursing students from June 4 to 15, 2020. Data analysis included t-test, ANOVA, and Pearson's correlation coefficients using the SPSS. As a result of the study, the knowledge of nursing students average level was 10.83, the average degree of attitude was 3.15, and the average degree of altruism was 3.57. As a result of analyzing the correlation between variable factors, the blood donation attitude and altruism(r=.447 p<.001) showed significantly positive correlation. The results of this study show that in order to increase the participation of blood donation to nursing students, voluntary participation through voluntary activities is main factor to increases voluntary participation, and it is necessary to change the blood donation attitude and perception of college students according to the current situation in which blood supply and demand is insufficient due to COVID 19.

Most of the early studies on plates vibration are focused on two-dimensional theories, these theories reduce the dimensions of problems from three to two by introducing some assumptions in mathematical modeling leading to simpler expressions and derivation of solutions. However, these simplifications inherently bring errors and therefore may lead to unreliable results for relatively thick plates. The main objective of this research paper is to present 3-D elasticity solution for free vibration analysis of continuously graded carbon nanotube-reinforced (CGCNTR) rectangular plates resting on two-parameter elastic foundations. The volume fractions of oriented, straight single-walled carbon nanotubes (SWCNTs) are assumed to be graded in the thickness direction. In this study, an equivalent continuum model based on the Eshelby-Mori-Tanaka approach is employed to estimate the effective constitutive law of the elastic isotropic medium (matrix) with oriented, straight carbon nanotubes (CNTs). The proposed rectangular plates have two opposite edges simply supported, while all possible combinations of free, simply supported and clamped boundary conditions are applied to the other two edges. The formulations are based on the three-dimensional elasticity theory. A semi-analytical approach composed of differential quadrature method (DQM) and series solution is adopted to solve the equations of motion. The fast rate of convergence of the method is demonstrated and comparison studies are carried out to establish its very high accuracy and versatility. The 2-D differential quadrature method as an efficient and accurate numerical tool is used to discretize the governing equations and to implement the boundary conditions. The convergence of the method is demonstrated and to validate the results, comparisons are made between the present results and results reported by well-known references for special cases treated before, have confirmed accuracy and efficiency of the present approach. The novelty of the present work is to exploit Eshelby-Mori-Tanaka approach in order to reveal the impacts of the volume fractions of oriented CNTs, different CNTs distributions, various coefficients of foundation and different combinations of free, simply supported and clamped boundary conditions on the vibrational characteristics of CGCNTR rectangular plates. The new results can be used as benchmark solutions for future researches.

The purpose of this study was to identify the degree of grit, resilience, academic self-efficacy, and learning flow of nursing college students in the COVID-19 situation to identify the factors that influence burnout. Data were collected by using questionnaires from 155 students who were in 3rd year of the nursing college in G city, from May 11 to May 25, 2021. Data were analyzed by t-test, ANOVA, Scheffe, Kruskal-Wallis test, Pearson's correlation, and multiple regression. Statistically, burnout showed a significantly negative correlation with grit, resilience and academic self-efficacy. Influencing factors on burnout were resilience, satisfaction of major, academic self-efficacy and satisfaction of clinic practice accounting for 60% of the total change. Based on this study, strategies to enhance resilience, satisfaction of major, academic self-efficacy and satisfaction of clinic practice are required to reduce the burnout of nursing college students in the COVID-19 situation.

Building on the framework of language socialization [10] in language learning and use, the present study examines the environmental factors involved in four college students' English learning in the situated place of the home during the COVID-19 pandemic. Using narrative inquiry, this study implements a time-series analysis to investigate undergraduates' online English learning in a rural area of northwest China. The data were collected via oral and written narration, semi-structured interviews, and class documents. Leveraging the field-habitus theories, the findings reveal that each of the students had a different habitus in the family field that influenced their English learning at home between March to July of 2020. Ultimately, all four students felt that their habitus made their online English learning ineffective and expressed that they did not wish to continue learning at home. The findings imply that it is important for rural parents to pay more attention to building college students' learning environments and helping students cultivate a strong learning habitus in the family field in northwest China.

This study sought to determine whether there were mediating effects on both mental health and sleep problems as induced by COVID-19 fears and its effects on preventive practices. The participants were 310 adults living in the Seoul/Gyeonggi Province. For data collection, an online survey was conducted using a semi-structured questionnaire. The collected data were analyzed using PROCESS Macro (Model 6) to validate the dual mediating effects. This study analyzed the direct effects of COVID-19 fears on the mental health problems, sleep problems and preventive practices. Both mental health and sleep problems had dual mediating effects in the influence of COVID-19 fears on preventive practices. Preventive practice has shown that the mediated effects of mental health problems play a strong role in instances when COVID-19 fears increase.
