Survey was done pre-, post- and followup- tests for 61 participants in the camp. The evaluation consisted of 53 questionnaires multiple-choice written test on the changes of knowledge and attitude. Factor analysis and reliability analysis were used to SPSS WIN18.0 verify questionnaire's reliability and validity, and paired t-test were carried out in order to analyze knowledge and shift in attitude. In addition, regression analysis was carried out in order to the relation between the satisfaction, knowledge and attitude. By this study, we showed as follows. First, knowledge were increased post- than pre-test, follow up- than pre-test(p<0.01). Second, shift in attitude changed positively post- than pre-test(p<0.01), follow up- than pre-test(p<0.05). Third, satisfaction was closely related to shift in attitude(p<0.01). Therefore, it suggested that the implement of human body exploration camp for elementary students could be an alternative strategy in health education.

  • Focus level has been important mental state in user study. Cardiac response has been related to focus and less clarified. The study was to determine cardiac parameters for recognizing focus level. The sixty participants were asked to play shooting game designed to control two focus levels. Electrocardiogram was measured during task. The parameters of time domain and frequency domain were determined from ECG. As a result of independent t-test, RRI, SDNN, rMSSD and pNN50 of time domain indicator were statistically significant in recognizing focus level. LF, HF, lnLF and lnHF of frequency domain were observed to be significant indicator. The rule base for recognition has been developed by the combination of RRI, rMSSD and lnHF. The rule base has been verified from another sixty data samples. The recognition accuracy were 95%. This study proposed significant cardiac indicators for recognizing focus level. The results provides objective measurement of focus in user interaction design in the fields of contents industry and service design.

  • The purpose of this study is to explore effective factors of elderly people's overall death anxiety and sub-dimensions of death anxiety. The subjects were 156 elderly people in S City, Gyeonggi-Do gathered by convenience sampling. This study collected data by interviewing the elderly who agreed to participate in the study and then analyzed it using SPSS 12.0 through descriptive statistics, the t-test, F-test, Sheffe-test, correlation analysis, and multiple regression. The respondents' overall death anxiety score was 2.61(±.47), and 'anxiety in the dying process'(2.94) had the highest points among sub-dimensions. Effective factors of overall level of death anxiety among the elderly were 'age' (β=-.18, p=.015), 'education' (β=-.16, p=.045), and 'economic status' (β=-.26, p=.003). In sub-dimensions, the elderly who were female, relatively young, and had low economic status showed high 'anxiety in the dying process'. As for 'anxiety over what will happen after one's death', the elderly who were relatively young, and had low economic status had high scores. Finally, on 'the loss of existence', the elderly who had poor relationships with their families had high scores.

  • This study was a descriptive research study conducted to determine how nursing students' good death awareness and nursing attitudes toward dying patients affect their empathy. The subjects of the study were 155 nursing students, and data were collected using an online survey method. Data analysis was performed using descriptive statistics, independent t-test, one-way ANOVA, and multiple regression using the IBM SPSS Statistics 26. Higher attitude toward care of dying (B=.312) had a statistically significant positive effect on empathy capacity (p<.010). The variables that affected nursing students' empathy capacity were end-of-life experiences of relatives (𝛽=.226) and attitude toward care of dying (𝛽=.220). The regression model was statistically significant (F=6.968, p<.001), explained 10.4% of empathy. This study is expected to be used as basic data for the development of programs to strengthen the empathy capacity of nursing students in the future.

Only data from 221 respondents however were used after screening data for reliability, and SPSS for Windows(21.0 version) statistical program was used to conduct descriptive analysis, factor analysis, reliability analysis, paired samples t-test analysis, independent samples t-test analysis and IPA matrix analysis. The following results were obtained. First, significant differences between the level of satisfaction and the level of importance were found for part of the selection attributes for each group. Second, Iquadrant was included with meals and information provided factors. IIquadrant was included with instructors and class program, information provided, accommodation factors. IIIquadrant was included in accommodation and meals, time-distance factors. IVquadrant was included in the information provided factor.

  • The purpose of this study was to investigate the effects of aqua exercise program on body composition, blood components, and physical fitness in the elderly women. This study included 23 elderly women. The aqua exercise program was performed for fifty minutes a day, 2 times a week for 12 weeks with moderate-intensity level. Data was analyzed with SPSS using descriptive statistics and the paired t-test. The findings of this study presented that the aqua exercise program showed significant improvements in the body mass index (t=2.42, p=.024), the abdominal circumference (t=4.36, p<.001), and the level of blood glucose (t=3.19, p=.004) and LDL cholesterol (t=3.33, p=.003). These results suggest that aqua exercise is an effective strategy which has positive effects on body composition and blood components among elderly women. It might be possible to promote health condition in elderly women by implementing aqua exercise program which could be considered aging and excercise intensity.

  • The exchange rate volatility during the global financial crisis in 2007-2009 led Korean shipbuilding companies to face currency risk. The use of foreign currency derivatives to take a risk in financial exposure affects them significantly. This research analyzes how the use of foreign currency derivatives affects the Korean shipbuilding industry in relation to its foreign sales by company type and over time, especially before and after the crisis period. It is based on statistical data presented by KOSHIPA and KOSIC in 2001-2014. The results of the analysis show that there is a significant relationship between foreign currency derivatives and foreign currency exposure for all firm sizes and years, but no relationship between them overtime.

  • This study was conducted to identify the effects of repeated cardiopulmonary resuscitation (CPR) training using smart learning on nursing students' knowledge, self-efficacy, and clinical competency. A quasi-experimental nonequivalent control group, pretest-posttest design was used. The subjects of the study were 102 nursing college students who had received CPR training for 6 months. The CPR training was divided into smart learning, lecture education, and practical education. Data were collected from November to December, 2016 and analyzed by descriptive statistics, ${\chi}^2$-test, t-test and one way ANOVA using the SPSS/WIN 21.0 program. The scores of cardiopulmonary resuscitation knowledge were higher in the lecture education group than the practical education group and the smart learning group. Scheffe's post hoc test revealed a statistically significant difference among groups (F=8.23, p=<.001). The self-efficacy of the practical education group was higher than that of the lecture education group and smart learning group, but this difference was not significant (F=2.46, p=.091). The clinical competency of the practical education group and smart learning group were higher than that of the lecture education group. Scheffe's post hoc test revealed that the value of clinical competency differed significantly among groups (F=59.90, p=<.001). Overall, the results showed that effective education differs based on nursing students' knowledge, self-efficacy, ad clinical competency. Combination training would be required for more effective repeated cardiopulmonary resuscitation training.
