Purpose: This study was to test the effects of a full body massage on labor pain and delivery stress reaction for primipara during labor. Method: This study employed a quasi- experimental method(nonequivalent control group, pre-post test design). The subjects of this study were 57 primipara hospitalized at the U OB & GYN hospital in Inchon from November 1. 2001 to July 31, 2002. 28 women were assigned to the experimental group and 29 to the control group. The experimental group was given 20 minutes full body massage for each of three delivery phases. The control group was given conventional delivery care. The levels of labor pain were measured by the Visual Analogue Scale and the expression scores of the labor pain and the levels of delivery stress reaction were measured by pulse rate, respiration rate, and blood pressure, and State-Anxiety Scale. Data were analyzed using the repeated measures analysis of covariance(ANCOVA), t-test, $X^2$- test, simple ANCOVA with SPSS program. Result: There was no interaction effect between time and group(F=.370, p=.693), but significant time effects were found for subjective labor pain(F=3.840, p=.028). There was no interaction effect between time and group(F=.112, p=.894), but significant group effects were found for objective labor pain(F=12.299, p=.001). There was no interaction effect between time and group for PR(F=.172, p=.843), RR(F=.626, p=.539), SBP(F=.089, p=.915), DBP(F=.748, p=.479), but significant group effects were found for SBP(F=7.547, p=.008). The level of status anxiety of the experimental group was significantly lower than the control group(F=11.787, p=.001). Conclusion: This study showed that the full body massage has partially positive effect on labor pain and delivery stress reaction. Therefore this study suggested that the full body massage might be used clinically to help primipara during labor.

This study was a descriptive study to identify the effect of health promoting behavior on fatigue and depression and to investigate these levels among nurses. Data were collected from September 19th 2012 to September 25th 2012 by questionnaires from 243 hospital nurses of 3 hospitals in Kyungsang-Bukdo. The data was analyzed using descriptive statistics, t-test, Pearson's correlation coefficients, ANCOVA, and Stepwise multiple regression. The result showed that in health promoting behavior, shift nurses had higher scores than it of non-shift nurses. The health promotion behavior predictors of fatigue were spiritual growth and stress management and the predictors of depression were physical activity and interpersonal relationship. This results suggest that development of professional health promoting program which is strengthened these parts of spiritual growth, stress management, physical activity and interpersonal relationship, is needed.

This study was conducted to identify a effect of the comprehensive self-regulation program for hypertensives as a nursing intervention on self-care performance and the physiologic parameters in rural areas. For this purpose, a nonequivalent control group and a pre and post-test quasi- experimental design was used. Fifty-four were evaluated subjects from two Community Health Practitioner Posts in the suburbs of Taejon City. The subjects of the control and experimental groups were matched for age and sex. The self-regulation program developed by author given to the experimental group. The program consisted of group education on hypertension and self-care, self-regulation including the blood pressure self-monitoring, recording of self-care activities, and encouraging and reinforcing self-efficacy. The whole program was carried out from September to November of 1999. The data were analyzed by repeated measure ANCOVA, t-test, and ANCOVA. The results were as follows ; There was significant improvement in the scores on knowledge (F=.68, P=.004), perceived self-efficacy (F=26.39, P=.000), self-care performance (F=26.11, P=.000) of the experimental group compared with those of the control group. There was no significant change on the score of locus of control, perceived benefits and perceived barrier, blood cholesterol level, body weight between two groups (P>.05). From these results, it can be concluded that the self-regulation program is an effective nursing strategy to promote self-care performance of hypertensives in rural area.

This study explored the effect of ASR-based pronunciation instruction, using a mobile platform, on EFL learners' pronunciation development. Particularly, this quasi-experimental study focused on whether using mobile ASR, which provides voice-to-text feedback, can enhance the perception and production of target English consonants minimal pairs (V-B, R-L, and G-Z) of Korean EFL learners. Three intact classes of 117 Korean university students were assigned to three groups: a) ASR Group: ASR-based pronunciation instruction providing textual feedback by the mobile ASR; b) Conventional Group: conventional face-to-face pronunciation instruction providing individual oral feedback by the instructor; and the c) Hybrid Group: ASR-based pronunciation instruction plus conventional pronunciation instruction. The ANCOVA results showed that the adjusted mean score for pronunciation production post-test on the Hybrid instruction group (M=82.71, SD =3.3) was significantly higher than the Conventional group (M=62.6, SD =4.05) (p<.05).
