Purpose: This study was to verify the effects of infant massage on weight recovery from physiologic weight loss, physical development of infants, and identity of their mothers. Method: A study with quasi-experimental design with time delay method was conducted from October 20, 2004 through February 20, 2005 with mothers and infants recruited from postpartum care center. 20 infants in the experimental group (once a day massage group) and 22 control group remained for the final analysis. Data were analyzed using SPSS win 11.0 program by frequency, percentage, mean, standard deviation, t-test and $X^2-test$. Results: There was no significant group difference in weight recovery from physiologic weight loss. However, experiment group showed significant increase in weight and chest circumference in 4 weeks after birth compare to the control group. For changes in behavior, experimental group showed more positive behavioral changes. The mothers who conducted massage for their infants showed higher score of identity as mothers. Conclusion: Since massage applied once a day can be still effective on physical growth of the infants, massage training program for mothers should be developed to apply easily for their infants at home. Further study is suggested to identify influencing factors on performed by mothers and identity as mothers.

Purpose: The purpose of this study were to develop a new restraint for the intensive care units (ICU) and to investigate the application effect in comparison with a control group using existing restraints. Method: A non-equivalent control group non-synchronized quasi-experimental research design was used. The participants were 40 (control 20, experimental 20) patients who were recruited by convenience sampling the ICU of a university hospital. To avoid contamination of the experiment, data for the control group were collected prior to the experimental group. Measurement variables were edema and skin damage (redness and abrasion) at the application site, and nurses' perceived convenience in applying restraints. Results: Three days after applying the restraint, amount of edema at the application site was small and incidence of skin damage decreased in the experimental group in comparison with the control group. Also, score for application convenience measured by the nurses was higher in for the newly developed restraint than for existing restraints. Conclusion: Results indicate that the newly developed restraint has lower effects such as edema and skin damage and is more convenient compared with existing restraints, and is therefore recommended for patients in the ICU.

Non-ductile detailing of Reinforced Concrete (RC) frames may lead to structural failure when the structure is subjected to earthquake response. These designs are generally encountered in older RC frames constructed prior to the introduction of the ductility aspect. The failure observed in the beam-column joints (BCJs) and accompanied by excessive column damage. This work examines the seismic performance and failure mode of non-ductile designed RC columns and exterior BCJs. The design was based on the actual building in Tainan City, Taiwan, that collapsed due to the 2016 Meinong earthquake. Hence, an experimental investigation using cyclic testing was performed on two columns and two BCJ specimens scaled down to 50%. The experiment resulted in a poor response in both specimens. Excessive cracks and their propagation due to the incursion of the lateral loads could be observed close to the top and bottom of the specimens. Joint shear failure appeared in the joints. The ductility of the member was below the desired value of 4. This is the minimum number required to survive an earthquake with a similar magnitude to that of El Centro. The evidence provides an understanding of the seismic failure of poorly detailed RC frame structures.

Purpose: This study was conducted to investigate the effects of a community-based death education program for older adults. Methods: The study was conducted as a quasi-experimental study with a non-equivalent control group and pretest-posttest design. The subjects were community elders aged over 65 registered at a community health center and were convenience sampled. The experimental group consisted of 33 participants and the control group consisted of 32 participants. Experiments are conducted from June 18 to July 24, 2020. We tested our hypothesis using an independent t-test, and paired t-test. Results: The experimental group had significantly higher scores for psychological well-being than the control group after treatment (t=2.24, p=.028). In general attitude toward the use of life-sustaining technology, however, only the experimental group had a significant difference before and after the experiment with lower scores compared to the control group (t=-5.41, p<.001). Conclusion: We found that the community-based death education program developed in this study was partially effective in improving older adults' psychological well-being and general attitude toward the use of life-sustaining technology.

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.

Purpose: The purpose of this study was to explore the effects of the lower limb muscle strength exercise program during hemodialysis on the leg strength and falls efficacy (fall-related self-efficacy) of hemodialysis patients. Methods: The study was designed to be a quasi-experimental, nonequivalent control group pre and post test design. A total of 42 patients participated in the study. We applied lower limb muscle strength exercise program to the experimental group in every hemodialysis three times a week for 8 weeks. Data were analyzed using ${\chi}^2$ test, fisher's exact test, t-test and repeated measures ANOVA. Results: The mean age was 58 years old (t=-1.54, p=.132), the mean hemodialysis period was 67 months (t=1.949, p=.058) and there was no significant difference of dependent variable (t=1.17, p=.251)(t=-.89, p=.381) between the two groups before the experiment. After the experiment, leg strength was significantly improved in the experimental group compared to that of the control group (F=6.63, p=.004). However, falls efficacy was not significantly different between the experimental group and the control group (F=2.33, p=.104). Conclusion: The study results indicated that the lower limb muscle strength exercise program during hemodialysis may improve leg strength and potentially to prevent falls for hemodialysis patients. Further studies are warranted in which larger number of participants and longer duration of intervention are recommended.

This study was designed to verify the effect of aromatherapy on menstrual cramps and dysmenorrhea by a quasi experiment (nonequivalent control group pretest-posttest design), from March to October, 2000. The subjects of this experiment consisted of 45 college women with menstrual cramps and dysmenorrhea. They were randomized by 25 for the experimental group and 20 for the control group. Their mean age was 20.6 years, mean menstrual period 28.7 days, mean menstrual cramps(VAS) 7.25, mean dysmenorrhea (Dysmenorrhea Scale) was 27.34. As treatment, aromatherapy was to give effleurrage of the abdomen with lavender, clary sage and rose as aroma oil, almond oil as carrier oil. For the control group, abdominal massage was given with only almond oil. Data collection included menstrual cramps, dysmenorrhea, the change of symptoms(low abdominal pain, lumbago, headache, nausea, fatigue, edema). Menstrual cramps, dysmenorrhea and general, menstrual characteristics of subjects were measured the first day of the pre menstrual period before treatment (pre-test), menstrual cramps, dysmenorrhea, the change of symptoms were measured the first and second day of post menstrual period after treatment (posttest). Data were analyzed by t-test, $\chi^2$- test, repeated measures ANOVA, Cronbach's ${\alpha}$ with SAS Program. The results of this study was as follows; 1. Menstrual cramps was significantly lower in the experimental group(p = .001). 2. Dysmenorrhea was significantly lower in the experimental group(p = .027). 3. Less women in the experimental group complained about the six symptoms than women in the control group after treatment on the first day of the menstrual period(p < 0.05, p < 0.01) In conclusion, these findings indicate that aromatherapy with lavender, clary sage, and rose could be effective to decrease menstrual cramps, and dysmenorrhea. So, aromatherapy could be applied to women suffering with menstrual cramps, dysmenorrhea periodically as an nursing intervention.

This study was designed to verify the effect of Doula-type-delivery nursing care on plasma $\beta$-endorphin, serum cortisol, related to delivery stress during labor, and postpartum anxiety of primipara by a quasi experiment(nonequivalent control group pretest-posttest design), from December, 1999 to August, 2000. The subjects of this experiment consisted of sixty eight primipara, with single gestation, full term, uncomplicated pregnancies, thirty three for the experimental group and thirty five for the control group. Their mean age was 26.1 years for the experimental group and 25.5 years for the control group. Their mean gestation period was 39.7 weeks for the experimental group and 40.1 weeks for the control group. As treatment, Doula-type-delivery nursing care was given for the experimental group. Data assessed plasma $\beta$-endorphin, serum cortisol during labor, and anxiety during postpartum. Plasma $\beta$-endorphin, serum cortisol were measured in the latent phase before treatment(pre-test) and the transition phase after treatment(posttest). Also, anxiety was measured in the latent phase before treatment(pre-test) and 24 hours postpartum after treatment(posttest). Data was analyzed by t-test, $x^2$-test, Repeated measures ANOVA with SAS Program. The results of this study were as follows; 1. Plasma $\beta$-endorphin was significantly elevated in the experimental group who were cared for with Doula-type-delivery nursing care during labor(P=.0463). 2. No significant group effects were found, but significant time effects were found for serum cortisol. 3. The postpartum anxiety of the experimental group was significantly lower than the control group(P=.0110). In conclusion, these findings indicate that Doula-type-delivery nursing care during labor could be effective in increasing maternal plasma $\beta$-endorphin and decreasing postpartum anxiety. Doula-type-delivery nursing care during labor could be applied as an effective nursing treatment for primipara.

Purpose: The purpose of this study was to evaluate the effects of hand acupuncture moxibustion therapy on elders' shoulder pain, ADL/IADL and sleep disorder. Methods: This is quasi-experimental with none equivalent control group pretest posttest design. The subjects were randomly assigned to one of Experimental Group A (Ceramic Seoammoxa therapy) (n=20), Experimental Group B (Seoampellet therapy) (n=18), Experimental Group C (Ceramic Seoammoxa and Seoampellet therapy) (n=20), and a control group (n=20). The intervention was applied 3 times per week for 6 weeks. NRS, Song's ADL/IADL scale, Oh, Shin and Kim's sleep disorders scale were used. Results: Hypothesis "Both shoulder pain and the level of sleep disorders of the experimental group A, B and C would be lower than the control group" was supported (p<.001). Hypothesis "ADL/IADL of the experimental group A, B and C would be higher than the control group" was supported (p<.001). In 3 weeks after the experiment, the experimental group A, B and C showed significant difference in change of ADL/IADL (p=.013). In 6 weeks after the experiment, the experimental group A, B and C showed significant difference in change of ADL/IADL (p<.001) and sleep disorders (p<.001). Conclusion: Consequently, the hand acupuncture moxibustion was an effective therapy in relieving shoulder pain and sleep disorders and improving ADL/IADL among elders.

Purpose: In this study a pilates exercise program using self-efficacy sources was provided for women 65 years of age or older and the effects on physical fitness, body composition, depression, self-efficacy, and health-related quality of life were tested. Methods: A quasi-experimental study employing a nonequivalent control group, pre-post design was conducted. The subjects consisted of 30 older women in the experiment group and 30 in the comparison group. The intervention was conducted twice a week for a period of 12 weeks. During this period, the pilates exercise program using self-efficacy sources (health education, phone coaching, mentoring, checking homework, recreation) were provided in the experiment group and pilates exercise program were offered in the comparison group. Chi-square test, independent t-test, ANCOVA were used for data analysis. Results: Following completion of the program, upper muscle strength (F=4.131, p=.047), low muscle strength (F=5.558, p=.022), upper flexibility (F=5.252, p=.026), static balance (F=5.957, p=.018), dynamic body balance & agility(F=18.971, p<.001), endurance(F=10.058, p=.002), muscle mass (F=5.748, p=.020), depression (F=4.493, p=.038), Self-efficacy (F=33.853, p<.001), and Health-related quality of life(F=5.586, p=.022) were significantly better in the experimental group. Conclusion: Findings from this study indicate that the pilates exercise program using self-efficacy sources are effective in enhancing physical fitness, body composition, self-efficacy and health-related quality of life and in decreasing depression for female elders and could therefore be regarded as positive program for promotion of physical and mental health for older women.
