This study examined the effects of emotional clarity and empathic ability on interpersonal competence among nursing college students. The subjects included college students in some provinces. The research period was November and December 2019. Two hundred and eighty five students were analyzed. The data collected were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation, and stepwise multiple regression analysis. The findings show that empathy (β=.551, p<.001), emotional clarity (β=.288, p<.001), and satisfaction with college life (β=.092, p<.001) had significant effects on interpersonal competence with an explanatory power of 47.4%. Interpersonal competence had significant positive correlations with empathy (r=.641, p<.001) and emotional clarity (r=.443, p<.001). Therefore, it is important to reinforce the development and application of customized individual counseling programs designed to enhance empathy. This encourages nursing college students to understand emotional clarity, which helps them recognize others' emotions as well as their own and make proper reactions. Accordingly, satisfaction with college life, which adds more vitality to their college life, will increase the interpersonal competence of nursing college students. In the future, repeating and in-depth research should be conducted to include emotional and psychological factors of interpersonal competence. A standardized research tool will be needed to measure interpersonal competence.

This study was designed to examine the influence of academic stress, anxiety, interpersonal dependency, and hopelessness on female high school students and their level of depression. The study subjects were 684 students attending an all-female high school in C city. Data were collected by self-administered questionnaires between November 1st, 2016 and December 31st, 2016. The data were analyzed using the SPSSWIN(ver. 21.0) program. The mean values of the level of depression were analyzed by the t-test and ANOVA. The correlation coefficientswereobtained by Pearson correlation analysis and acovariance structure analysis was performed on the factors affecting the level of depression. It was found that the level of depression among all of the subjects was significantly higher within the group with a higher level of academic stress, anxiety, interpersonal dependency, and hopelessness. Thus, the level of depression was positively correlated with the levels of academic stress, anxiety, interpersonal dependency, and hopelessness. The factor that had the most influence on depression was the anxiety factor, followed by interpersonal dependency and academic stress. This result suggests that the level of depression in female high school students has a causal relationship with academic stress, anxiety, interpersonal behavioral characteristics, and hopelessness. Therefore, the most effective strategy to reduce the level of depression among female high school students would appear to be efforts to decrease their academic stress, anxiety, and interpersonal dependency.

The purpose of this study is to analyze the effect of average unit learning on the knowledge of the representative value of 5th grade elementary school students. In the information-oriented society, the ability to organize and summarize the data has become an essential resource. In the process of correctly analyzing statistical data and making reasonable decisions, the summary of the data plays an important role, and it is necessary to learn the concept of representative values in order to describe the center of the data in a series of numbers. For research, an informal knowledge type possessed by a fifth grade elementary school student with respect to a representative value before learning an average unit is examined and compared with the representative value after learning the average unit. A suggestion point for representative value guidance in school mathematics is provided while examining the change in knowledge with respect to the representative value. Seeing the informal types of elementary school students' representative values will help them learn how to formalize the concept of representative values in middle and high schools. It will give suggestions about the concept of representative values and the method of instruction that should be dealt with in elementary schools. The informal knowledge about the representative value can help with formal representative value that will be learned later. Therefore, This study's discussions on statistical learning of elementary school students are expected to present meaningful implications for statistical education.

The purpose of this study was to evaluate effects of a nutrition education focused on Food Exchange System for the higher grades elementary children. Nutrition education lessons (40 min/lesson, 4 times), '5 major nutrients and functions', '6 food groups', 'daily needed energy and food exchange units', 'good choice of snacks and balanced exercise' were provided to elementary students (5th grade students). This research was based on the data from two groups of elementary school children in the 'education' group (n = 31) and 'non-education' group (n = 31). We assessed the changes in dietary attitude, food habit and nutrition knowledge using questionnaire and nutrient intake using 24hr recall method by nutrition education using the developed pamphlet. After education, there was a significant difference in the dietary attitude score only in attitude of 'balanced meal' (p < 0.001) in the education group compared to the non-education group. In food habit, there were significant positive changes in the type of breakfast and in the priority of choosing snack in the educated group. In nutrition knowledge, there were significant increases in scores of 'function of carbohydrate' (p < 0.05), 'function of fat' (p < 0.01), 'function of vitamin' (p < 0.01), 'foods of carbohydrate' (p < 0.01), and 'foods of vitamin' (p < 0.01) in the educated group. After education, carbohydrate: protein: fat (CPF) ratio was significantly different between the two groups (education group, 59 : 16 : 26 vs. non-education group, 63 : 15 : 23). In evaluation of nutrient intake by Dietary Reference Intakes for Koreans (KDRIs), there were significant positive effects in energy (p < 0.05), thiamin (p < 0.05), riboflavin (p < 0.05), vitamin C (p < 0.05), phosphorus (p < 0.01), Fe (p < 0.01) and zinc (p < 0.01) in the education group compared to the non-education group. In conclusion, the developed 4 times' nutritional education pamphlet focused on individual daily energy requirements and food exchange units using food exchange system for higher grades' elementary student may positively change nutrition knowledge and dietary intakes.

The purpose of this study was to evaluate the shear bond strength of three light-cured glass ionomer cements to blood contaminated bovine dentin. The materials used in this study were Fuji II LC, Dyract and Variglass VLC. The dentin conditioners were 10% polyacrylic acid, 10% maleic acid and 10% phosphoric acid. 180 lower anterior bovine teeth were selected in this study. The teeth were embedded in acrylic resin and were grounded with 320 to 600 grit silicon carbide paper to create a flat dentin surface. The teeth were divided into SIX groups. The experimental procedures in six groups were as follows; Group l(GF) : Samples bonded to dentin surface with Fuji II LC after 10% polyacrylic acid treatment. Group 2(BGF) : Samples bonded to dentin surface with Fuji II LC after 10% polyacrylic acid treatment and blood contamination. Group 3(MD) : Samples bonded to dentin surface with Dyract after 10% maleic acid treatment. Group 4(BMD) : Samples bonded to dentin surface with Dyract after 10% maleic acid treatment and blood contamination. Group 5(PV) : Samples bonded to dentin surface with Variglass VLC after 10% phosphoric acid treatment. Group 6(BPV) : Samples bonded-to dentin surface with Variglass VLC after 10% phosphoric acid treatment and blood contamination. Group 1,3 and 5 were classified into the control groups, while group 2,4 and 6 were classified into the experimental groups. Each group contained 30 samples. After 24 hours water storage at $37^{\circ}C$, all smples were subjected to a shear load to fracture at a cross head speed of 1.0 mm/min with Instron universal testing machine(No. 4467). Debonded surfaces were observed under Scanning Electron Microscope(Hitachi S-2300) at 20kvp. The data were evaluated statistically at the 95% confidence level with Student's t-test. The following results obtained; 1. Shear bond strengths were higher in the control groups(1,3,5 group) than in the experimental groups(2,4,6 group). 2. The shear bond strength of group 5(PV) was the highest in the control groups, and the group 5 was significantly higher than the group l(GF) on the shear bond strength. 3. The group 4(BMD) was the highest on the shear bond strength, and the group 2(BGF) was the lowest in the experimental groups. The group 4(BMD) and 6(BPV) showed a significant difference with the group 2 on the shear bond strength. 4. All the groups showed an adhesive-cohesive failure. except the group 2(BGF) showing adhesive failure.

This study is a qualitative study on the case of teaching mathematics between parents and children. 12 lesson units were applied to the 5th grade elementary school child for the first semester, 2019. The purpose of this study was to identify conceptual understanding in the area, the types of problems that child felt difficult during the learning and parents' advantages and difficulties in this setting. For this study, video recording and voice recording were collected for each lesson class. The concept of the area was recognized correctly, the awareness of reconstruction became clear, and the concept of partitioning, unit iteration and structuring an array was more clearly rebuilt. He showed difficulty in conversion between units of the area, in displaying height of the shape whose height is displayed outside and drawing type of figure with same area after the value of the area was offered. In the learning situation of parents and children, parents who are researchers have the advantage of being able to customize up to their children and being free from time and cost constraints. There were difficulties in controlling negative emotion toward the child, determining the level of the children, distribution the class time and deciding the degree of intervention. Furthermore, research on parenting and child-to-parent teaching in mathematics is recommended.

Comparative studies using large-scale data such as TIMSS, PIRLS, and PISA inform us of the effectiveness of each educational system. Even though samples in the large-scale studies were representative, admitting potential discrepancy when applying the findings of the large-scale studies to local educational system is still needed. This study examines the structural relationship among students' attitude towards science, learning support from teachers, school life, and science academic achievement with both large-scale data and local comparative study data utilizing same variables. Responses on the TIMSS 2019 of 5,554 Korean seventh-grade students and National Assessment of Educational Achievement (NAEA) 2019 of 6,365 third-grade middle school students were used. The results indicate that: a) school life did not affect the science achievements in both data. However, in NAEA 2019, students' attitude mediated the relationship between school life and science achievement; b) learning support from teachers had a significant impact on TIMSS science achievements, and also had positive effect on achievement through students' attitude in TIMSS. On the other hand, learning support had a positive effect on achievement only when student's attitude mediated the relationship in NAEA; c) students 'attitude toward science had positive effect on science achievement on both data; d) the impact of gender was different on school life, academic achievement, students 'attitude towards science, and learning support from teachers on both data; and e) the impact of the number of books differed as well. There were differences in results between the international and domestic research, which inform us that we need to pay attention when interpreting the domestic environment through the results of international research.

This study was conducted to investigate the relationship between political interest, economic interest, sociocultural interest and intention of maintaining the nursing job against 291 nursing students from a university in C city from August to September 2022. The collected data were analyzed by t-test, ANOVA, and Pearson's correlations. The study showed political interest 3.35(maximum 5 points), economic interest 3.76(maximum 5 points), sociocultural interest 4.15(maximum 5 points), and intention of maintaining the nursing job were 3.40(maximum 5 points). In the correlation between variables, the correlation coefficient between political interest and sociocultural skill(r=.385, p<.01) was high, and economic interest and overall sociocultural interest were the most correlated(r=.534, p<.01). For the correlation with intention of maintaining the nursing job, sociocultural behavioral intention(r=.158, p<.01) and attitude(r=.131, p<.01) were statistically significant. Based on the results, repeated studies including political, economic, and sociocultural interest as variables influencing intention of maintaining the nursing job and future research on systematic and diverse educational programs including sociocultural attitudes and behavioral intention are suggested so the nursing job can be maintained for longer time as a profession.

Objective: This study evaluated the pregnancy and implantation rates in fresh IVF-ET cycles or frozen-thawed ET (F-ET) cycles based on serum estradiol concentrations of controlled ovarian hyperstimulation (COH). Methods: Clinical outcomes of 1,565 cycles of fresh IVF-ET with COH and 670 cycles of F-ET were retrospectively analyzed. Serum estradiol levels on the day of human chorionic gonadotropin (hCG) administration were categorized into Group-A (1,000$\sim$2,000 pg/ml), Group-B (2,000$\sim$3,000 pg/ml), Group-C (3,000$\sim$4,000 pg/ml) and Group-D (> 4,000 pg/ml). Clinical pregnancy (CPR), implantation (IR) and delivery rates (DR) were compared among four groups subdivided into younger (< 35 years) and older ($\geq$ 35 years) women. Statistical analysis was performed by Student's t-test and chi-square test. Results: Overall clinical outcomes with fresh IVF-ET and F-ET cycles were similar: 41.2% vs 44.8% of CPR, 18.8% vs 19.6% of JR, and 33.2% vs 34.5% of DR, respectively. There were no significant differences in the clinical outcomes of all four groups between fresh IVF-ET and F-ET cycles of younger women according to the estradiol levels. However, the clinical outcomes of F-ET cycles of older women in Group-D were significantly higher than those of fresh IVF-ET cycles (51.3% vs 25.0% of CPR*, 18.6% vs 9.9% of IR and 33.3% vs 19.4% of DR;* p<0.05). Conclusion: Our results demonstrated that supraphysiological levels of estradiol during COH in fresh IVF-ET cycles of older women ($\geq$ 35 years) may be detrimental to implantation environments of endometrium and clinical outcomes, which could be improved by F-ET cycles.
