Purpose: This study was done to develop a new nursing intervention, Meridian Massage, and to investigate its effect on weight in infants and mother-infant interaction. Method: This study was conducted using a quasi experimental non equivalent control group pretest-posttest design. Thirty-one newborn infants from a postpartum Management Center were selected and assigned to two groups, experimental and control. Data were collected from February 1 to September 30, 2004. Infants in the experimental group (16) were given Meridian massage for 15 minutes daily for 6 days and weighed every day at 10 am. Using the Nursing Child Assessment Feeding Scale(1978), mother-infant interaction was determined before the treatment, after 1 week and 1 month after the massage. Results: Infants in the experimental group had a higher average weight than those in the control group and the difference was significant (Z=-2.29, p=.022). For mother-infant interaction, the experimental group had higher scores tHan the control group, and the difference was significant between both the two groups, and the 3 measurement times. Conclusion: The Meridian Massage in this study showed positive weight gain and positive mother-infant interaction. This study shows that meridian massage is an effective nursing intervention in improving infant development.

The purpose of this study was to investigate the effect of massage therapy on weight gain, length and head circumference in instituted infants. This study utilized nonequivalent control group with repeated measuring by quasi experimental design. Fifty eight instituted infants in Daejeon city were selected for the study. Fifty eight infants were randomly assigned two groups, one served as the control group and the other was experimental group to whom massage therapy was given. For the experimental group, massage protocol(developed by Field, 1986) was applied 2 times a day, mid-morning and early evening, for 4 weeks for each infants by researcher and trained research assistants. As a weight weighing instrument, electronic indicator scale (Cas Co., Korea) was used. The result of this study were summarized as follows; 1.A repeated measures ANOVA identified a significant group by time effect over the four weeks of intervention(F=14.69, p < .0001). Infants assigned to experimental group gained more weight than control group infants. 2. T-test identified that significant differences in length(t=2.60, P=.013) and head circumference(t=4.27, P=.000). Infants assigned to experimental group had more length and head circumference than control group infants. In conclusion, Massage therapy improved weight gain, length and head circumference of instituted infants. Therefore, it is recommended to utilize massage therapy as a nursing intervention for instituted infants.

The study investigated the effects of differences in some electronic course designs on university students' Computational Thinking Skills (CTS). Towards this end, the researcher adopted the experimental research design of a quasi-experimental of two experimental groups. The first group was taught an e-course designed in a sequential pattern, and the other group's course was designed according to the holistic model. A CTSs test was prepared to collect the relevant data, and the data were analyzed statistically using these tests- Pearson correlation Mann Whitney and Alpha Cronbach. Results revealed statistically-significant differences at the level α=0.05 between the mean scores of the first and second experimental groups in favor of the latter in the CTS test. The findings gave ground to put forward some salient recommendations, including the need to expand computational thinking in universities' educational process. It also recommends urging faculty members to enhance e-courses in the educational process and provide technical support to students and faculty members.

This study was developed to evaluate the effectiveness of a multicultural education program for college students. To this end, the program was designed to offer them a series of twenty lectures for three months, 60 hours in total, and a quasi-experimental design was employed to evaluate the difference between pre-test and post-test scores of participants of both experimental group(N=45, Mdiff=.378) and control group(N=47, Mdiff=.036) on their attitudes on cultural diversity. Also, pre-test and follow-up test scores were compared to confirm whether the effect was sustained. The results showed that while the pre-post difference was statistically significant for experimental group participants(t=4.264, p=.000), the difference was not significant for control group students. Furthermore, the effectiveness of the program was sustained among students in the experimental group at a 3-month follow-up test(t=2.466, p=.016). In conclusion, the multicultural education program, in fact, proved to be effective in changing the attitudes of college students in understanding and accepting different cultures in Korean society.

Purposes: The purpose of this study was to identify recent trends of experimental research by analyzing doctoral dissertations in all colleges of nursing in Korea. Methods: The areas of research, the content, methodological and intervention characteristics used in this study were explored in experimental research on doctoral dissertations (n=132) published from 2006 to 2010. Results: In the issues of research, practice/clinical issues were most frequently used. As to outcome measurement, physiological variables increased more than psychological/emotional variables. Most theory applied in the research was taken from other disciplines, and nursing theory was only Roy's adaptation theory. A large majority of the research was quasi-experimental designs and the number of true-experimental designs was very low. In more than half of the dissertations, internal validity was not described, and the described external validity rate was very low. There were more single intervention programs than bundle ones and education/exercise programs were most frequently used as the source of intervention. Conclusion: Doctoral dissertations need to increase and encourage more high quality experimental research to expand nursing knowledge and to develop evidence based nursing practice.

This paper is studied on a new DCM-ZVS step up-down AC-DC converter of high performance, that is, high system efficiency and power factor correction (PFC). The switching devices in the proposed converter are operated by soft switching technique using a new quasi-resonant circuit, and are driven with discontinuous conduction mode (DCM) according to pulse width modulation (PWM). The quasi-resonant circuit uses a step up-down inductor and a loss-less snubber capacitor. The proposed converter with DCM also simplifies the requirement of control circuits and reduces the number of control components. The input AC current waveform in the proposed converter becomes a quasi-sinusoidal waveform proportional to the magnitude of input AC voltage under constant switching frequency. As a result, the proposed converter obtains low switching power loss and high efficiency, and its input power factor is nearly in unity. The validity of the analytical findings is confirmed by some computer simulation results and experimental results.

Background: The aim of this study was to determine the impact of applied progressive muscle relaxation training on the levels of depression, anxiety and stress among prostate cancer patients. Materials and Methods: A quasi-experimental study was conducted at the University Malaya Medical Centre (UMMC) and Universiti Kebangsaan Malaysia Medical Centre (UKMMC) over six months. Prostate cancer patients from UMMC received the intervention and patients from UKMMC were taken as controls. The level of depression, anxiety and stress were measured using Depression, Anxiety Stress Scales - 21 (DASS-21). Results: A total of 77 patients from the UMMC and 78 patients from the UKMMC participated. At the end of the study, 90.9% and 87.2% of patients from the UMMC and UKMMC groups completed the study respectively. There were significant improvements in anxiety (p<0.001, partial ${\eta}^2$=0.198) and stress (p<0.001, partial ${\eta}^2$=0.103) at the end of the study in those receiving muscle training. However, there was no improvement in depression (p=0.956). Conclusions: The improvement in anxiety and stress showed the potential of APMRT in the management of prostate cancer patients. Future studies should be carried out over a longer duration to provide stronger evidence for the introduction of relaxation therapy among prostate cancer patients as a coping strategy to improve their anxiety and stress.
