Having developed a parent education program for guidance of internet-using children, we evaluated the effectiveness of this program. The program consisted of five two-hour sessions. It was test-run with nineteen participants, which included mothers of elementary school children. In the evaluation of the program, we employed so-called 'pretest-posttest control group design' which compares the difference in the parenting sense of competence, parents' sense of role satisfaction, parents' sense of insecurity, and parents' rearing attitudes between the experimental group and the control group. Program evaluation revealed that the parenting sense of competence and role satisfaction increased in the group that participated in the program compared to the non-participating group. Furthermore, the parents' sense of insecurity decreased and democratic rearing attitudes were fostered in the participating group.

Objective: This study employed a pretest-posttest quasi-experimental design to evaluate the effectiveness of the Respected Parents & Respected Children(RPRC) parent education program developed for working mothers of dual-income families with young children. Methods: A total of 32 working mothers were randomly assigned to two groups, an intervention group (n = 16) and a control group (n = 16). Mothers in the intervention group participated in the parent education program. After the termination of the program, differences between the pretest and posttest in terms of mothers'parenting behaviors, parenting efficacy and parental role satisfaction were compared in both groups. Results: Mothers in the intervention group were significantly improved in their parenting behaviors and parenting efficacy, whereas mothers in the control group did not show any significant differences between pretest and posttest scores. However, there was no significant difference in parental role satisfaction between the intervention group and the control group. Conclusion/Implications: These findings suggest that RPRC parent education program is effective in bringing about positive changes in working mothers'parenting confidence, which can be crucial for the future developmental outcomes of their children.

The purpose of this study was to test the effects of a epilepsy education program as a nursing intervention for patients with epilepsy. A quasi treatment research (non equivalent control group pretest-posttest design) was used in this study. The subjects were 40 epilepsy patients visiting an outpatient department of a general hospital in Daegu city.(treatment group : 20 patients, control group : 20 patients). The study was carried out from June, 1998 to September, 1998. Data was collected before the education program (pretest), immedately after(posttest 1) and 4 weeks later(posttest 2) and were analyzed with repeated measures ANOVA, t-test, Chi-sqare test and Pearson correlation coefficient. The results are as follows : There was a significant difference in epilepsy self efficacy between two groups(F＝26.27, p＝.000). There was a significant difference according to pretest, posttest 1 and posttest 2(F＝111.20, p＝.000), and interaction effect between treatment and time(F＝109.42, p＝.000). There was a significant difference in epilepsy self management between two groups(F＝78.02, p＝.000). There was a significant difference according to pretest, posttest 1 and posttest 2 test(F＝94.02, p＝.000), and interaction effect between treatment and time(F＝88.14, p＝.000). There was a significant correlation(r＝.76, p＝.000) between epilepsy self efficacy and epilepsy self management. These results suggest that a epilepsy education program is effective ill promoting self efficacy and self management of the patient with epilepsy. Thus this program can be recommended as an effective nursing intervention for the epilepsy patients.

Purpose: The objectives of this research are to verify the development and effectiveness of a nursing student emotional competency promotion program that is important in professional nursing strategies for strengthening the psychological well-being of patients. Methods: This research was done by developing an emotional competency promotion program for nursing students according to the analysis, design, development, implementation, evaluation (ADDIE) model. Apply the program to students and evaluate their effects on their self-awareness, self-management, social awareness, relationship management and self-efficacy using a nonequivalent control group pretest-posttest design. The subjects of this research were 48 nursing students enrolled in the department of nursing of D College; 24 students were placed in the experimental group and 24 students were in the control group. The experimental group participated in the developed program from December 18, 2017 to January 12, 2018, for a total of 8 sessions. Each session was 120 minutes long. For data collection, a pretest, posttest 1 and 2 were performed using an independent t-test and repeated measure ANOVA using SPSS/WIN 22.0. Results: The experimental group who participated in the emotional competency promotion program showed higher self awareness (F=5.65, p=.005), self management (F=11.12, p<.001), social awareness (F=5.02, p=.009), relationship management (F=11.22, p<.001) and self-efficacy (F=14.24, p<.001) than the control group. These results were supported by a statistically meaningful difference in the time period and the interaction between the time period and the two groups. Conclusion: The study's findings indicate that the emotional competency promotion program developed through this study is effective at increasing the self-awareness, self-management, social awareness, relationship management and self-efficacy of nursing students.

Purpose: This study aimed to investigate the effects of restorative family circles (RFCs) on empowerment and family support for people with mental illness, and the belief system and caring experience of their families. Methods: This study used a quasi-experiment with a non-equivalent control group pretest-posttest non-synchronized design. Ninety-two dyads of patient-family caregivers were recruited using convenience sampling and assigned to the experimental and control groups. The subjects of the experimental group participated in RFCs consisting of eight 90-minute sessions. Data were collected at three different times (pretest, posttest, follow-up test) and analyzed for the effects of RFC using the 𝑥² test, Fisher's exact test, Mann-Whitney U test for homogeneity between groups, and generalized estimating equation models. Results: The findings of this study showed that there were significant differences in the family support for people with mental illness between the pretest and follow-up test, and also in the belief system and caring experience of the family between the pretest and posttest. Conclusion: This study revealed that family interventions based on restorative justice emphasizing community-driven conflict management could be used in psychiatric mental health nursing care for fostering a cohesive family relationship.

Purse: The purpose of this study was to examine the effect of a laughter therapy on mental health promoting like depression, laughing index of elderly. Methods: The study was conducted based on the non-equivalent control group pretest-posttest design. The participations included 12 older adults in the control group and 11 in the experiment group. Data was collected from October 1 to November 22, 2013. Experimental group participated in laughter therapy six times, once a week for 60 minutes of each session. Questionnaires were used to measure pretest and posttest levels of depression and laughing index. Results: At the end of six-week intervention, depression score (z=-2.95 p=.003) and laughter index score (z=-2.81 p=.005) was significantly decreased in the experimental group compared to the control group. Futhermore, there was a significant difference in the depression scores of the experiment group at the posttest, but no signigicant difference was found between the two groups. Conclusion: The study results suggest that the laughter therapy is an effective intervention to reduce the depression but helpful to enhance the laughing index. Therefore, it is expected that laughter therapy will serve as an emotional nursing intervention for elderly patients with depression.

The purpose of this study was to analyze the effects of using the geometric manipulative for the development of spatial sense and thus to find out a better mathematics teaching and learning method that could help develop students' spatial senses. The two fifth grade classes were randomly chosen as an experimental group (31 students) and a control group (32 students), respectively. This study implemented nonequivalent control group pretest-posttest design of quasi-experimental design. The test instrument used in this study was a spatial sense test. The pretest and posttest were implemented with the same instrument. In addition, their classes were observed and videotaped, and the data and their study activities were analyzed. In conclusion, first, the geometric manipulative-aided activities contributes to developing students' spatial senses and their two sub-factors involves perceptual consistency and perception of spatial relationship. Second, the activities of grasping the components of solid figures, sketches and development figures by using the geometric manipulative contribute to boost students' perceptual consistencies and their perceptions of spatial relationship.

Purpose : This was aimed to investigate the effects of empirical smoking prevention program on the knowledge of the harmfulness of smoking, attitude to smoking, smoking temptation among female high school students. Methods : This study used nonequivalent control group pre and post test design. The subjects were recruited from the first and second grade at the two girls' high schools located in Ulsan city, and randomly assigned to two groups(113 in the experimental group and 117 in the control). The intervention was both the events such as nonsmoking promulgation and experiential learning programs and student-oriented educational sessions(once a week for six weeks). Data was analyzed with X2 test, t-test and ANCOVA. Results : The mean knowledge was 12.5 for pretest and 13.7 for posttest in the experimental group, and 12.7 and 13.4 in the control group, retrospectively. The mean attitude was 71.0 for pretest and 72.2 for posttest in the experimental group, and 72.3 and 72.6 in the control group, retrospectively. The mean temptation was 15.0 for pretest and 14.7 for posttest in the experimental group, and 13.9 and 14.0 in the control group, retrospectively. There's no difference in the change of the knowledge of the harmfulness of smoking, attitude to smoking, smoking temptation between experimental and control groups. Conclusion : As the possible reasons, the subjects already had sufficient knowledge on the harmfulness of smoking, the research questionnaires were too plain to get any difference, the effect of intervention was too small to show a difference in such as short-term, and finally, there were many external factors. Hence, we recommend further studies with appropriate questionnaire for longer time.

Purpose: The purpose of this study were to develop a respiratory communicable disease prevention program for preschoolers and measure it's effects. Method: The respiratory communicable disease prevention program for preschoolers consisted of texts, cartoons, photographs, discussions, demonstrations, puzzle games, die games, compensation/reinforcement, and token economy which were directed under the systematic design of instruction by Dick ％amp; Carey. This study was a quasi experimental study under the nonequivalent control group with pretest-posttest design. The subjects of this study were 45 preschool children who are attending 3 different district nursery schools and they were matched by the age, pretest knowledge, and pretest behavior. The instrument used in this study was criterion referenced test items that were developed by a researcher for evaluating the subject's knowledge, attitude, and behavior about respiratory communicable disease prevention. A pretest was administered a week before treatment. Experimental group Ⅰ was administered by the treatment of respiratory communicable disease prevention program. Experimental group Ⅱ was administered by above program with token economy program. The posttest was conducted on the eighth day. The third test for behavior was completed 15th day. To determine the effect of the program, the data were analyzed by the SAS 6.12 program with Kruskal Wallis test, ANCOVA, ANOVA, Duncan's test and paired t-test. Result: 1) There was a significant difference in knowledge between the experimental groups and control group(F=5.89, P=0.0197). 2) There was a significant difference in attitude between the experimental groups and control group(F=3.29, P=0.0469). 3) There was a non-significant difference in behavior between the experimental groups and control group(F=0.00, P=0.9512). 4) In the experimental groupⅡ, there was highly significant increase in behavior after token economy(t=4.5252, P=0.0005). Conclusion: It was found that the respiratory communicable disease prevention program for preschool children was effective in changing the preschoolers' knowledge and attitude on the respiratory communicable disease prevention, but not enough for changing the preschoolers' behavior. Token economy was improved as an effective and strong method for inducing desirable changes of preschoolers' behavior.

Support has always been considered an important nursing concept. However, there is no agreement among nurse researchers as to a conceptual definition of supportive nursing or meaningful supportive behaviors. Clarification of the concept, support in nursing, is necessary to promote communication among nurses on nursing behaviors that are effective in providing support and on understanding the relevant properties and charcteristics of the concept, supportive nursing care. The objectives of the study were : 1. to analyse the concept, support in nursing, in order to provide a definition of supportive nursing care, and 2. to operationalize the definition of supportive nursing care and use it as an experimental nursing intervention for patients with low back pain. The first part of the study used the concept analysis approach developed by Walker and Avant(1983) to define the concept of supportive nursing care. The properties of supportive nursing care, defined by this analysis, included perception of supportive need, reciprocal interaction(Transaction), listening, providing empathy and information related to health, and confirmation of the patient's verbal and non - verbal response. The second part, the experimental part of the study, was done using King's(1970) Interpersonal Theory for Nursing. The concept, supportive nursing care, as defined in the concept analysis was operationalized and used as the experimental intervention. The experiment tested the effectiveness of the independent variable, supportive nursing care on the dependent variables, depression, mood and patient satisfaction, in the patients with low back pain in army hospitals. The instruments used to measure the dependent variables were Zung's(1965) Self- Rating Depression Scale, Ryman and Colleagues'(1974) Mood Questionnaire and LaMonica and Colleagues'(1986) Patient Satisfaction Scale. The experimental design used for this study was a Solomon 4 group experimental design. This design has the strength of allowing for observation of the main effects of supportive nursing care and pretesting, and for observation of the interaction effects of pretesting and supportive nursing care. The design includes one experimental group and three control groups. The Subjects of this study were 150 young male patients with low back pain on Neuro - Surgical Wards in three general army hospitals. There were 35 in the experimental group, 39 in the pre - posttest control group, 36 in the treatment - posttest control group and 40 in the posttest only control group. Supportive nursing care, as operationalized by the researcher according to the concept analysis, was given to the patients in the experimental group and the treatment -posttest control group, individually for 30 minute sessions, every other day for 5 days. Data collection was done using a questionnaire. The data were collected in a pretest one week before the supportive nursing care sessions, a posttest immediately after the sessions and follow- up test one week later. Hypotheses testing was done using 2×2 factorial analysis of variance and Meta analysis(Stouffer's Z method). The results of this study are summarized as follows : 1. Hypothesis Ⅰ, “There will be a difference on depression level between the patients with low back pain who receive supportive nursing care and those who do not receive supportive nursing care”, was supported (F＝8.49, p＜.05). 2. Hypothesis Ⅱ, “There will be a difference on mood level between the patients with low back pain who receive supportive nursing care and those who to not receive supportive nursing care”, was supported (Z meta＝2.17, p＜.05). 3. Hypothesis Ⅲ, “There will be a difference on satisfaction level between the patients with low back pain who receive supportive nursing care and those who do not receive supportive nursing care”, was supported (F＝13.67, p＜.05). 4. ANOVA, done to examine the interaction effect of history and maturation, showed no significant difference on the dependent variables between the observations of the pretest scores of the experimental group, the pretest scores of the pre- posttest control group and the posttest score of the posttest only control group. 5. To test for continuing effect of supportive nursing care, paired t-test was done to compare the scores for the dependent variables at the posttest and at the one week later follow-up test. No significant difference on the scores for the dependent variables was found between the posttest scores and the follow-up test scores for the two groups that received supportive nursing care, the experimental group and the treatment-posttest control group. In conclusion, it was found that in the case of young soldiers with low back pain in army hospitals, their depression level was decreased, their mood state was changed positively and their satisfaction level was increased by receiving supportive nursing care. Further, the effectiveness of the supportive nursing care lasted for at least one week in this study. The significance of this study to nursing is in the analysis of the concept of supportive nursing care and the demonstration of the effectiveness of supportive nursing care as an intervention within the limits of the study.
