This paper presents a sensitivity analysis to obtain best fit of hydraulic parameters of leaky fractal aquifer. The sensitivity analysis uses the least squares method. The hydraulic parameters (generalized transmissivity and generalized storage coefficient) can be easily determined by the sensitivity analysis for various flow dimensions and different values of the leakage factor. Furthermore, the sensitivity analysis was applied to variable-rate pump tast at several abstraction wells, A computer program was developed to evaluate the hydraulic parameters by the sensitivity analysis.

This study examined the effect of infant teacher's sensitivity, efficacy and interaction on the social and emotional development of infants. The participants of this study were 169 infants and their teachers in daycare centers located in Seoul and Gyeonggi-do. The instruments were collected through teachers' responses. Data were analyzed through the variance analysis using PASW 18.0 to verify the infant teachers' susceptibility, efficacy, and infant-teacher interaction based on infant teachers' background variables; to find out the relationship between the variables, Pearson correlation analysis was performed, and to find out the relative influence of variables on the infants' social and emotional development, stepwise multiple regression analysis was performed. Results were as follows. Firstly, Among the background variables of the teachers, their career as infant teachers displayed differences in the infants' social and emotional development, and the susceptibility, efficacy, and infant-teacher interactions displayed partial differences based on the teaching career, career as infant teachers, age, daycare center type, and the academic background of the teachers. Secondly, there were positive relationships between infant teacher's sensitivity, efficacy and interaction and infants' social and emotional development. Thirdly, infant teachers' sensitivity, efficacy and infant-teacher interaction had an influence on infants' social and emotional development at the same time. Especially, sensitivity and interaction were powerful and influential variables and their explained variance was 53%. These results suggested that teachers' efforts must be made to interact positively with infants and to increase their sensitivity level to respond to infants in order to increase infants' social and emotional development.

This study was to examine the effect of Displaced aggression and Justice sensitivity(victim sensitivity and penetrator sensitivity) on Cyberbullying tendency in 20s adult, and the moderating role of Justice sensitivity to identify psychological factors affecting a serious social problem, cyberbullying. The online survey was handed to 261 adults in their 20s for a month. First, Simple regression analysis shows that displaced aggression(F=62.55, p<.001) and victim sensitivity(F=29.61, p<.001) predict cyberbullying tendency. Second, hierarchical regression analysis by controlling the effects of sex, the perpetrator sensitivity has been shown to morderate the relationship between displaced aggression and cyberbullying tendencies(F=29.61, p<.001), and the effect of victim sensitivity has not been significant. In conclusion, that future studies need to consider the limitations of this study to ensure that the same results are shown in different age groups and also some approaches such as empathetic understanding could help to reduce cyberbullying.

Structural instability and damage are caused by frost heave during the winter when atmospheric temperature maintains below $0^{\circ}C$. Frost heave is the most representative engineering characteristics of frozen ground and there are various frost susceptibility criteria. Frost susceptibility criteria can be roughly divided into three categories. First, frost susceptibility is determined from particle size distribution, which is practically useful and many countries are adopting. In this paper, several particle size distributions (PSDs) are applied to the frost susceptibility criteria but PSD seems to be not enough to determine whether soils are frost susceptible. Second, it is judged from laboratory frost heave testing results. Laboratory frost heave tests were performed with newly developed thermal controlled triaxial cell and the reliability of frost susceptibility criteria is evaluated. New testing apparatus and method are suitable to meet the existing frost susceptibility criteria. Third, it is compositive frost susceptibility criteria envelope including the particle size distribution, soil classification, and frost heave test. The compositive frost susceptibility criteria envelope should be supplemented based on additional data on various soil types.

In the study, the moral sensitivity, moral distress, and biomedical ethics awareness levels of hospital nurses are examined, and the mediating effect of biomedical ethics awareness in the relationship between moral sensitivity and moral distress is verified. As the study subjects, 153 hospital nurses were selected from both university hospitals and general hospitals in S city and J city. Using the SPSS WIN 21.0 system, data analysis was conducted via t-tests, the Sheffe test, correlation analysis, multiple regression analyses, Sobel test. The average level of moral sensitivity experienced by the hospital nurses was 4.70(out of 7), moral distress was 62.80(out of 336), and biomedical ethics awareness was 2.21(out of 4). Moral distress had a static correlation with moral sensitivity and biochemical ethics awareness, and moral sensitivity had a static correlation with biomedical ethics awareness. Finally, biomedical ethics awareness showed a partial mediating effect in the relationship between moral sensitivity and moral distress. It is important to develop a biomedical ethics education program that can help hospital nurses to resolve moral issues, thereby improving moral sensitivity and diminishing their moral distress.

The purpose of this study aims to be used as base data of a policy which forms university students' appropriate behavior for the prevention of infection by analyzing some university students' prevention awareness of new type of infection. A self-administered questionnaire survey about students' seriousness, sensitivity, self-efficacy, and prevention behavior intent of new infection, was conducted in an university located in Gyeonbuk from April. 30th to May. 11th, 2018. Analyzing factors which affect the prevention behavior intent of infection with controlled general factor and health behavior, the prevention behavior intent was increased by ${\beta}=.125$ as seriousness increases and ${\beta}=.709$ as self-efficacy increases in Model 2, final model. However, sensitivity has no significant effect on the prevention behavior intent. Originally sensitivity has to be a significant factor regarding to the prevention behavior intent of new infection. But the result that sensitivity has no influence at all, shows that the students are insensitive to new diseases as they don't fear or sense danger of new infection. Therefore, a disease control policy which helps to increase sensitivity has to be established.

Objective: The purpose of this research is to explore the influence of infant teachers' teaching efficacy and sensitivity level on organizational commitment. Methods: The subjects of the study were 206 infant teachers working in pre-schools in "Region S." In the research, a survey was given out using a teaching efficacy tool used by Hee-Kyung Kwak (2011), a teacher-sensitivity measurement scale created by Kwang-Mi Min (2014), and an organizational commitment measuring tool modified and improved by Jong-Kak Lee (2013). The collected data went through the SPSS 21.0 Win Program to gather the information regarding reliability analysis, technical statistics, correlation analysis, and multiple regression analysis. Results: First, the infant teachers' teaching efficacy was average, their sensitivity level was above average, and their organizational commitment was a little above average. Second, the infant teachers' teaching efficacy and the organizational commitment showed a static relation. The sensitivity level showed a static relation with affective commitment and normative commitment in organizational commitment. Third, the infant teachers' organizational commitment was largely influenced by general efficacy which is a subfactor in teaching efficacy, and by consistency which is a subfactor of sensitivity. Conclusion/Implications: The results of this research suggest that teachers' teaching efficacy and sensitivity level are crucial in improving their organizational commitment.

Here we report a simple screening system using hematoxylin staining (HS) of the root apex. It allowed rapid classification into different aluminum (Al) tolerance from 65 cultivars within one week. Using this system, we selected the most Al-tolerant (Jayae-2) and-sensitive (Pum-2) barley (Hordeum vulgare L.) The results show that the different responses in Al-induced growth inhibition, Al accumulation and expression of plasma membrane (PM) $H^+$-ATPase in root apices of selected two cultivars. It showed strongly Al-induced growth inhibition in a dosedependant manner only in Pum-2 but not in Jayae-2. Aluminum accumulation in root apices (10 mm) was significantly higher in Pum-2 only. The $H^+$-ATPase expression of PM vesicles by western blotting was decreased in Pum-2 but not in Jayae-2 treated with $20{\mu}M$ Al for 24 h. These finding indicate to screen from our system is rapid and reliable and to sustain the expression of PM $H^+$-ATPase at translational level is an important role in root growth as affected by Al.
