The purpose of this study was to identify risk factors related to sexual function of women with coronary artery disease, and to determine the predictors of sexual function. The study design, a descriptive correlational study, was done through structural questionnaire and interview. A total of 50 subjects from C University Hospital at Kwang-ju city who have undergone coronary angiography at department of cardiology were observed and interviewed from Feb. 22, 1999 to March. 23, 1999. The number of affected vessels, the level of total serum cholesterol, and the ejection fraction of 2-D echo cardiography were analyzed to evaluate the severity of coronary artery disease. And also type A behavior pattern, health behavior, Brief Index of Sexual Functioning for Women (BISF-W) were measured. The data obtained were analyzed using percentage, mean and standard deviation, t-test, ANOVA, Pearson's correlation coefficient, and stepwise multiple regression analysis via SPSS PC+. The results of this study were as follows: 1. The mean age of the subjects were 58.1 and 72.0% of those have been married over 30 years. Seventy two percentage were unemployed and monthly family income of 56.6% was less than 1,000,000 won (approximately $ 840). Eighty percent were in their postmenopausal state, and the frequency of sexual intercourse of 84.0% were two to three times per month. 2. The scores of type A behavior pattern were from 16 to 38(mean 24.94) and health behavior ranged from 21 to 43(mean 31.2). Abstinence from smoking, alcohol, and caffeine were best compliant factors and weight control and exercise were least abided ones. The result of 2D-ECHO EF showed that the half of the subjects were abnormal, and 24% had more than 240mg/dl of total serum cholesterol. The coronary angiography showed that 64% of the subjects had more than one affected vessels. 3. The predictors to explain the factor score of 'orgasm' were number of health examination, the pre- or post-menopausal state, protestant, number of coronary vessel affected, level of serum total cholesterol, and comorbid group of hypertension and diabetes, and it's total variance accounted for 52.4%. The predictors to explain the factor score of 'sexual activity' were comorbid group of hypertension and diabetes and type A behavior pattern, which accounted for 22.4% of total variance. The predictors to explain the factor score of 'sexual satisfaction' were type A behavior pattern, no religion, exercise, level of serum total cholesterol, and pre or post menopausal state, which accounted for 52.1%. The predictors to explain the factor score of 'sexual desire' were the period of marriage, type A behavior, employment or unemployment, and weight control, which accounted for 43.2%. The predictors to explain the factor score of 'external force of sexual functioning' were physical overload and exercise, which accounted for 41.1%. The predictors to explain the factor score of 'sexual activity' were family monthly income, catholics, and exercise, and which accounted for 35.4%. Above results lead us to some consensus that sexual function of women with coronary artery disease is related to various factors including vasogenic factors such as total serum cholesterol level, number of coronary vessel affected, an endocrinal factor such as menopausal state, and type A behavior pattern as a sociopshychological factor. And also health behaviors such as fitness care, overwork, weight control, and emotional tension are contributed to sexual function.

This study investigated the impact of student-centered instructions on students' academic achievement in science and on their attitudes toward science. Participants included 208 middle school students. The pre- and post-test control group design was employed. The control group was designed to have traditional instructions while experimental group 1 was applied both student-centered instructions and traditional instructions, and experimental group 2 was applied student-centered instructions only. The chaper of "Stimulus and Response" was selected for this study, and students were treated for 15 hours. Data were analysed using ANOVA. Results indicated that student-centered instruction had a significant effect on students' academic achievement(p<.01). The improvement of achievement through student-centered lesson is neither depending on genders nor previous academic achievement levels. Student-centered instruction also had a significant effect on students' attitudes toward science(p< .01). Only half of the class if a student-centered lessons and improve attitudes toward science could be. The improvement of the attitudes toward science through student-centered instruction is not depending on genders. But, student-centered instruction was more effective on the average student and the lower level students than the upper level students.

Purpose: The purpose of this study was to identify whether hearing a recording of mother's voice affected physiological reactions, behavioral state related to sleep and weight of very low birth weight (VLBW) infants. Methods: This was a nonequivalent control group pre-post test quasiexperimental design. The participants were 11 VLBW infants in the experimental group and 11 in the control group. In the experimental group, a recording of mother's voice was played to her infant by voice recorder four times each day for five minutes over 10 consecutive days in the incubator. Results: For physiological response (heart rate, respiration rate, oxygen saturation), there were statistically significant differences between the experimental and control groups. Behavioral state during sleep was more very quiet and quiet in the experimental group. In the daily weight change, there was no significant difference between the experimental and control groups. Conclusion: The findings suggest that, for VLBW infants, the intervention of hearing a recording of mother's voice had some significance as a nursing intervention having a positive impact. Such interventions can help pediatric nurses to stabilize the physiological response and maintenance more very quiet sleep state and improve VLBW infants' growth.

Until now, research to integrate art activities and science education have been making steady progress in the field of primary education and early childhood education that are directly involved in the art education of students. However, some science educators were interested in visualizing the artifacts by using design principles and experimental results through STEAM education. So, when conducting lessons for integrating science education with art activities, research is needed on the changing of the students' ability. Therefore, the purpose of this study is to investigate the effect of science experiments in collaboration with art activities for students' self-directed learning skills and creative personality in elementary school. This study was applied to 30 students(16 male, 14 female) of 4th grade in Changwon C elementary school. The teaching materials of this study was extracted some of the experiments from the 2007 revised national curriculum in elementary science textbook and 'Teachers for Exciting Science'. Experimental treatment was performed over a total of 10 class 5 subjects and a pre-post test was conducted through G-TAGAS. As a result, science experiments in collaboration with art activities have improved significantly students' self-directed learning skills and creative personality.

The purpose of this study is to have a preliminary study in order to identify changes in occupational performance skills and visual perception of patients with mild dementia, who have been provided with a group occupational therapy program, within community day-care center. The subjects of this study were 9 people with mild dementia living in a community. The period of administration was for 60 minutes per session three times a week during four weeks. We assessed their visual perception function(MVPT) and occupational performance(AMPS). One group pre-post test design was implemented as an experimental study to compare the results between before and after applying the group occupational therapy program within sensory, physical, creative activity. While a statistically significant difference between before and after the program of motor skills(occupational performance skill) is not shown, the visual perception function and occupational performance of patients with mild dementia improved significantly after receiving occupational therapy program(p<0.01, p<0.05). Therefore, it is possible to conclude that the group occupational therapy program is helpful to manage the occupational performance skills and visual perception of patients with mild dementia in community day-care center.

This study aimed to examine the effects of integrated simulation practice education for nursing college students on their communication skills, self-efficacy in learning, clinical reasoning ability, and clinical performance through a pre-post quasi-experimental design with a single group. The participants were 41 fourth-year nursing college students from a university located in G City, and the intervention took place from September to November 2023 over a period of nine weeks. The collected data were analyzed using SPSS 23.0, and the research findings are as follows. First, after simulation practice education, significant effects were observed in self-efficacy in learning (t=-2.21, p=.033), clinical reasoning ability (t=-2.97, p=.005), and clinical performance (t=-2.84, p=.007), but no significant difference was found in communication skills (t=-.224, p=.824). Second, after simulation classes for nursing students, clinical performance showed significant positive correlations with communication skills (r=.650, p<.001), self-efficacy in learning (r=.440, p<.001), and clinical reasoning ability (r=.824, p<.001). Based on these results, integrated simulation practice education for nursing students appears to be an effective educational method for enhancing their self-efficacy in learning, clinical reasoning ability, and clinical performance. To improve nursing students' clinical performance, it is necessary to operate simulation practices with various scenarios.

Tensile constitutive stress-strain model of steel fiber reinforced concrete (SFRC) in fib MC2010 was investigated. In order to model tensile behavior of SFRC, three point loading flexural tests were conducted on notched small beams according to BE-EN-14651. Design parameters for the constitutive model were determined from the flexural tests. Flexural test and finite element analysis were conducted on large SFRC beam without steel reinforcements and compared with each other. In addition, parametric study on the effect of compressive and tensile model, and characteristic length on flexural behavior of the SFRC beam was conducted also. In results, pre-peak load-displacement curves from the FE analysis was close to experimental curves but significant difference was shown in post-peak behavior. The reason of the difference is originated from the fact that the fiber distribution and orientation were not being properly considered in the MC2010 model. This study shows that modification and detail explanations on the orientation factor K in MC2010 might require to better reproduce the behaviour of large scale SFRC beams.

This research aims is to confirm the effects of cultural competence of an action learning based teaching method in multicultural nursing education. Cultural competence was composed of cultural knowledge, cultural awareness and cultural acceptance. A total of 118 college students were enrolled in this study. Both before and after learning, the students were guided to fill out a questionnaire regarding culture competence. The students from each group studied multicultural nursing by different teaching types: the Traditional Lecture-based Teaching method (TLT) and Action Learning based Teaching method (ALT). Data analysis was carried out by SPSS 21.0. A pre-post comparison within the group was performed using a paired t-test and the comparison between groups was performed using ANCOVA. The results showed that there was a significant difference in the culture competence in both teaching methods. In addition, ALT showed higher cultural acceptance results than TLT; however, there was no difference in cultural knowledge and cultural awareness between the two groups Therefore, ALT should be considered as a teaching method to enhance cultural competence in multicultural nursing education for Nursing students. Further studies on instructional design according to the task types, nursing performance, and the validity of ALT will be needed.
