  • This study investigated the effects of meaning of life and depression on the health-promoting behaviors of community-dwelling elderly people, as well as the effects of community programs on their depression, meaning of life, and health-promoting behaviors. Collected data were analyzed by ANOVA, paired t-test through SPSS/WIN 18.0 program. The demographic characteristics, depression, meaning of life, and health-promoting behaviors of the participants were analyzed using descriptive statistics that calculated real numbers and percentages. The participating in community programs resulted in a decrease in depression(t=2.379, p=.010) and significant increase in meaning of life(t=2.421, p=.009) and health-promoting behaviors(t=2.316, p=.012) and recognized the importance of community role for healthy old age. Based on this, we propose active participation of the community for the health of elderly people and development of programs suitable for the subjects.

  • This study was a clinical Quasi-experiment to examine the effects of the range of motion exercise on powerlessness and life satisfaction among the E-Institutionalized elderly in Pusan. The purpose was to test the effect of the range of motion exercises on powerlessness and life satis-faction, and to examine the correlation between powerlessness and life satisfaction. The subjects for this study were 54 elderly people, both were over 60 and residing at I-Institution in Pusan. The research samples of 54 elderly were divided into an experimental and control group by matching randomized assignment. The instruments for this study were the Assessment Tool of Powerlessness in the elderly developed by Miller, Life satisfaction developed by Yoon Jin, and the Active-Passive Range of Motion Exercise Program which was developed and utilized by Shin, Jae-Shin. The data were collected from December 15, 1990 to November 1991. The paired t-test, t-test and ANCOVA were used to test hypothesis I and II, related to the Effect of the Range of Motion Exercises to powerlessness and life satisfaction. To identify the relationship of the range of motion exercises to powerlessness and life satisfaction, path analysis was done through multiple regression. The interrelationship of the variables was analyzed using t-test paired t-test. The results of the three hypothesis can be summarized as follows : 1. Hypothesis I -the experimental group which participated in the Range of Motion Exercise gets lower powerlessness score than that of the control group-was accepted by t-test (t = -3.40, p = .001) but not accepted by ANCOVA (F = .1, p =.96). 2. Hypothesis II - the experimental group which participated in the Range of Motion Exercise gets a higher Life Satisfaction Score than that of the control group-was not supported by t-test(t = 1.01, p = .316) but was accepted by ANCOVA (F = 4.39, p = .006). 3. Hypothesis III - if the powerlessness Score becomes higher, the Life Satisfaction Score will be-come lower - was accepted by Pearson Correlation Coefficient (pre-exercise : r : -.34, p=.006), (post exercise : r = -.06, p=.32) . The relation-ship between the score of powerlessness and life satisfaction was negatively correlated. The results obtained clearly showed that the effects of the range of motion exercises on powerlessness and life satisfaction are beneficial to the elderly The relation between the scores of powerlessness and life satisfaction was negatively correlated and the range of motion exercise had a direct influence to powerlessness. Therefore, it is concluded that the relationship between powerlessness and life satis-faction was not a causal one. Also it is concluded that the range of motion exercises can be applied as a nursing intervention to reduce powerlessness and to improve life satisfaction in the elderly.

  • This study was aimed to identify a study on the effect of chest compressions combined with abdominal drawing-in technique on prevention of back pain and chest compression quality. We tested motion analysis, electromyography, and chest compression quality of 15 paramedics. Data were normalized to SPSS 21.0 (Kolmogorov-Smirnov and Shapiro-Wilk test). The paired t-test was used for the pre- and post-test chest compressions, the one-way ANOVA was used for the analysis of the measurement point-in-time differences, and LSD was used for the post-test. The results of the study showed significant difference in muscle activity and chest compression success rate when the chest pressure was applied with abdomen drawing-in. Therefore, it is necessary to study cardiopulmonary resuscitation education which can increase the chest compression success rate while preventing the back pain of the paramedics in the future.

The study was designed using a nonequivalent control group pretest-posttest design, and data were collected from June 1 to August 31, 2017. The participants consisted of 52 nursing students in D College of D City who were assigned to an experimental group (n=27) or control group (n=25). The pretest poll was performed on June 1, 2017 and posttest poll was performed 2 weeks later without any treatment in the control group. In the experimental group, the pretest poll was performed on July 25 before the emergency treatment education program and the posttest poll was performed on August 31 after the education program. The emergency treatment education program for the experimental group consisted of 2 hours of emergency treatment instruction, autonomously watching videos, and 4 hours of teaching elementary students about CPR for adults and first aid for airway obstruction, burns, bleeding, and fractures as a lecturer. The data were analyzed using descriptive analysis, independent t-test, $x^2$ test, and paired t-test with SPSS/WIN 20.0. After receiving the emergency treatment education program, a difference was observed in self-leadership (t=2.08, p<.05), career decision-making self-efficacy (t=4.22, p<.05) and nursing performance ability (t=5.02, p<.05) in the experimental group.

  • The purpose of this study was to analyze and determine the level of the satisfaction and awareness of facilities in child care centers among teachers and parents. Special attention was given to both the indoor and outdoor environments from the viewpoints of both parents and teachers. The subject of this research focused on parents who leave their children at child care centers, and teachers who work for the center. The data was compiled by performing both T-tests and paired T-test. The information was processed by a program called SPSS WIN 10.0. The results were as follows ; 1. (a) With regard to the satisfaction of the external and internal facilities : It was determined that both the play rooms and the wall-pattern arrangements were satisfactory to both the parents and the teachers. (b) Regarding the awareness of the importance of facilities, while the parents focused more on the play rooms and the external environments, the teachers placed more importance on the bathrooms and the play rooms. 2. In the paired T-test that determined whether their individual opinions were different in terms of the satisfaction and awareness of facilities, it was interesting to see that both the parents and the teachers showed significant differences in their opinions and priorities about the porches, the play rooms, the bathrooms and the wall-pattern arrangements. In general, their awareness was much higher than the satisfaction with these facilities. 3. In the T-test that determined whether there were any tendencies in the satisfaction and awareness respectively in the two groups, the satisfaction rate was higher among the parents than the teachers. In terms of the awareness of the importance of the facilities, the teachers rated the bathrooms and the wall-pattern arrangements as a priority.
