  • The study was to find whether the educational program contributed to increase of knowledge and self-efficacy of the postpartal primiparas. This study aimed at improvement of the educational effect for postpartal primiparas. The Subjects were 34 primiparas who were admitted to the obstetric ward in a University hospital from November 15th to December 9th, 1999. The Subjects were those who had no labor pain at the admission time, had no complications during labor and delivery and, gave birth to a healthy baby. They were tested on knowledge and self-efficacy two times, one at the admission time and prior to discharge. After the first test nurses in a maternity ward taught them on postpartal care. Two tools were developed by authors based on literature review. The test tool fr knowledge of postpartal car consisted of 23 items. The test tool for self-efficacy of postpartal care consisted of 16 items. Analysis of demographic data were analyzed with calculation of percentage. Score differences between the first test and the second test were analyzed with paired t-test. The Spss (Win 8.0) program was used for data analysis. The results are as follows. 1. There were not significant influencing general characteristics of primiparous to pre-educational knowledge. There were significant influencing general characteristics of primiparous to post-educational knowledge : occupation(t=13.04, p=0.00), postpartal education(t=5.51, p=0.02). 2. There were not significant influencing general characteristics of primiparous to pre-educational self-efficacy. There were significant influencing general characteristics of primiparous to post-educational self-efficacy : antenatal education(t=5.53, p=0.02) 3. Primiparas' knowledge of postpartal care increased significantly after education(t=13.04, p=0.00). 4. Primiparas' self-efficacy of postpartal care increased significantly after education(t=5.51, p=0.02). 5. Correlation between knowledge and self-efficacy was r=.360(p=0.03). We suggest follow-up studies to find whether primiparas' self-efficacy will last after discharge or not.

  • Purpose: To evaluate the results of meniscal repair and partial meniscectomy of lateral meniscus injury associated with tibial plateau fracture. Materials and Methods: Between February 1993 and August 2004, 24 cases (23 patients) of lateral meniscus tear with tibial plateau fracture were evaluated retrospectively. The most frequent type of tear was the longitudinal tear of the meniscocapsular junction (14 cases, 66.7%). All fractures were reduced under the control of arthroscopic and image intensifier. Arthroscopic repair of the longitudinal tear of the lateral meniscus or arthroscopic partial meniscectomy was performed. The final results were evaluated with the Ikeuchi criteria and Lysholm score. Results: At the final follow-up, the outcome was excellent in 12 cases (85.7%), good in 1 case (7.1%) and fair in 1 case (7.1%) among 14 cases of meniscal repair, and the excellent in 4 cases (66.7%) and good in 2 cases (33.3%) among 6 cases of partial meniscectomy according to the Ikeuchi criteria, There was a significant improvement of Lysholm score after surgery, 92.3 postoperatively compared with 56.6 preoperatively (p<0.0001, paired t-test). Conclusion: The fracture of the lateral tibial plateau did not seem to affect on the healing of the meniscus repair and partial meniscectomy.

  • The purpose of this study was to identify the effects of online practicum based on action learning on self-directed learning ability, academic self-efficacy, and cooperation ability of nursing students. Similar experimental study of single group pre-post test design was used to investigate the effects of this online class. A total of 47 nursing students who were junior grade from one college participated in this study and self-administered questionnaire was used for data collection. Data were analyzed by frequencies, paired t test using the SPSS/Window 21.0 program. The result of this study showed that the improvement after online practicum based on action learning was significant in self-directed learning ability(t=3.832, p<.001), academic self-efficacy(t=4.258, p<.001), and cooperation ability(t=3.853, p<.001).

  • This study intends to identify the effect of the simulation-based adult nursing education on resilience, clinical competence, and role transition of nursing students. Similar experimental study of a single group pretest-posttest design was used to investigate the effects of the program. The study was conducted from March to June, 2017 on senior nursing students at the university in M city who take an 'Integrated nursing practice I' class for the semester. Data were collected through self-report questionnaires and data of 52 participants were analyzed. The data were analyzed by frequencies, paired t-test and pearson's correlation coefficient using SPSS 21.0 program. As a result, the effectiveness of the simulation-based adult nursing education on resilience, clinical competence, and role transition were found. The result of this study showed that the improvement after simulation education was significant in resilience(t=-2.51, p=.016), clinical competence(t=-4.18, p<.001), and role transition(t=-2.89, p=.006). Resilience was found to be positively correlated with clinical competence(r=.464, p<.001) and role transition(r=.473, p<.001). These findings imply the value of simulation education to enhance the resilience, clinical competence, and role transition of nursing students. In the future, more studies should be conducted in the same group with control group to validate the effectiveness of variables.

  • The effects of positive psychology promoting programs for undergraduate nursing students were evaluated. The study was designed using a nonequivalent control group pretest-posttest design; data were collected between June 22 and September 4, 2019. The participants were 37 nursing students, who were assigned to an experimental group (n=18) and a control group (n=19) at two colleges in D and P city. The positive psychology-promoting program was provided for six weeks (12 sessions, 100~120 min.). The data were analyzed using descriptive analysis, t-test, 𝑥2 test, repeated measure ANOVA, and paired t-test with the SPSS/WIN 21.0 program. After receiving the positive psychology-promoting program, a difference in optimism (F=16.74, p<.001), psychological well-being (F=14.69, p<.001), and stress-coping strategy (problem solving; F=4.35, p=.015, social support; F=3.87, p=.028) was observed between the experimental and control groups. The results indicate that the positive psychology-promoting program was effective in increasing optimism, psychological well-being, and stress coping strategy in undergraduate nursing students. These findings will contribute to the development of a program to improve the mental health of undergraduate nursing students.

  • The purpose of this study is to provide basic data for the development of pre-parent education program by grasping parent role recognition, educational needs and readiness of unmarried men and women. The subjects were 196 unmarried male and female students from K-do. Data were collected from November 1st to 20th, 2018, and analyzed using IBM SPSS WIN/21.0 to get frequency, percentage, average, standard deviation, t-test, ANOVA, sheffe-test, paired t-test, and IPA matrix. The average score of recognition of social pre-parent role was $3.41{\pm}0.27$ (out of 5 points), educational needs was $3.48{\pm}0.41$ points (out of 4 points), and educational readiness was $2.65{\pm}0.57$ points (out of 4 points). educational needs being higher than educational readiness. Through IPA matrix analysis, the area to be strengthened was 'family relation or parent role', and 'self understanding' was the area to encourage putting effort into other evaluation attributes. The area where no further effort is needed and needs improvement in the future was 'spouse selection and marriage', and 'pregnancy and childbirth' and 'child rearing' were the areas to intensively improve. Therefore, there is a need for establishing a standardized strategy in the area A, which has high degree of readiness and needs. Also, it is necessary to take strategies and countermeasures to raise the readiness of area C with low degree of readiness and needs, rather than accepting it as an unnecessary area of further effort input.
