The purpose of this study was to test whether Yoga exercise, one of muscle relaxation, helps to relieve chronic low back paln. Sample were selected from nurses who were worked at K medical center in the period from March 18 to April 23, 1996. The sample size was fifteen. The research design was one-group pretest-posttest design. To test the major research question, this study had the following procedure. The pretest included measuring individuals' degree of pain and discomfort depending on the scope and types of an range of motion, and their pain by their activity of daily living(ADL). The treatment was conducted twice every other week. The reason why this study had twice observations was to control history effect and maturation which treat internal validity in the research design of this study. In this research design, a treatment was to expose Yoga exercise to samples. The exercise was taken in 30 minutes per day for four days in a week (Two consecutive days and twice every other day). The posttest included re-measuring the individuals' the degree of pain and discomfort, and their pain by their ADL. Several hypotheses concerning effect of Yoga exercise was analyzed by the paired t-test, comparing the difference scores between pre and post tests. The results of this study was as follows. The first hypothesis that the post-treatment group taking the Yoga exercise had the pain score lower than the pre-treatment group was supported(t=3.31, p=.005). The second hypothesis that the discomfort score of the post-treatment group had lower than does that of the pre-treatment group was supported(t=2.75, p=.016). The third hypothesis that the post-treatment group had the pain score by ADL lower than does the pre-treatment group was supported(t=5.52, p=.000). In summary, this study examined the effect of a yoga exercise, one of muscle relaxation, on those who were suffered from chronic low back pain. The effect measured by the degree of pain and discomfort with a visual analog scale was statistically significant. The degree of pain according to postures in ADL also showed statistical significance. These findings showed that a yoga exercise was effective to alleviation of chronic low back pain. A pretest-posttest control group design, however, needs to get more accurate results since the design satisfies Internal validity. Consequently, yoga as an exercise cure improves an interaction between muscles and articulations, and performance of ADL for those suffered from chronic low back pain. Furthermore, this positive impact may be an effective method as nursing intervention for their physical, mental, emotional, social, and psychological recovery.

Background: Many trials have been conducted the methods and types of intervention of form rollers, but no research has been done yet that mixes the methods and types of intervention. Objectives: To analyze the effects of myofascial release on the improvement of range of motion (ROM), flexibility, pain pressure threshold, and balance. Design: Randomized controlled trial. Methods: All subjects measured ROM, flexibility, pressure pain threshold, and dynamic balance by pre-test. After pre-test, subjects were randomized that static-vibration foam rolling group (n=12), dynamic-vibration foam rolling group (n=12), general foam rolling group (n=12). For the intervention, 3 sets of 90 seconds were applied to each group, and rest time was set to 60 seconds between sets. In the post-test and follow-up test after 10 minutes, all three groups were measured the ROM, flexibility, pressure pain threshold, and dynamic balance. Results: The results of comparing ROM, flexibility, pressure pain thresholds, dynamic balance ability appeared higher significant difference in the pre-post-10 minutes follow up test in comparison between time in the intragroup (P<.001). As a result of comparing the change of pre-post-10 minutes follow up, static vibration foam rolling showed higher significant difference compared to control groups (P<.001). Conclusion: Through this study, when foam rolling is applied within the same intervention time, static foam rolling can be expected to have a better effect than the existing dynamic foam rolling as well as vibration foam roller can expect better effect than general foam rolling.

Purpose： This study was to develop and verify the effects of drug misuse and abuse preventive program for middle school students. Methods：This research was a quasi experimental study under the nonequivalent control group with pretest-post test design which tried to protect children from the detrimental effect of drugs and develop a drug abuse prevention program for middle school students. Data was collected from October 10th to 21th, 2005. Subject consisted of 145 middle school students in Kyeonggi, experimental group-72, control group-73. Dick & Carey's(1996) educational system was applied, based on documents and materials online related to drug abuse in order to develop drug abuse prevention program. It's composed of 4 parts, 45 minute each. The evaluation instrument testing for the knowledge about drugs was a criterion of referenced test items modeled by Dick & Carey. The instrument for attitudes about drugs was modeled by Kim, Soyaja. A pre-test was taken on the knowledge and attitudes to drugs. The experimental students were given four sessions of drug abuse prevention education. A post-test similar to the pre-test questionnaire was given in 1 week, 4 weeks following the last session. Collected data was analyzed by using SAS 9.1 program. Results：Followings are the summarized result of study 1. The experimental group, that attended the drug abuse prevention program will have more knowledgable about drugs than the control group (F=27.31, p<.0001). 2. The experimental group, that attended the drug abuse prevention program displayed greater negativism attitude than the control group (F=0.58, p=0.4477). Conclusion：The results conclude that drug abuse prevention programs increase the knowledge of middle school students but doesn't change their attitude toward drugs. Therefore we need to offer them more systematic education to increase their knowledge so it will also improve their attitudes as well.

Purpose: This study was undertaken to identify the effects of a camp-type group counseling program based on the self-determination theory, for controlling smartphone usage amongst university students. The program consisted of smartphone overdependence, basic psychological needs, and adaptation to college life. Method: This was a quasi-experimental research with a non-equivalent control group design (pre-test and post-test design). A total of 38 freshmen (17 experimental and 21 control) participated in the study. Experimental subjects attended a two nights and three days camp, where the group counseling program included meetings for basic psychological needs (eg., autonomy, competence, and relatedness). Results: This study showed significant differences in basic psychological needs (Z=-2.91, p=.003) and adaptation to college life (Z=-3.47, p<.001). Although no significant difference was obtained in the degree of smartphone overdependence (p=.194), mean score of the experimental group pre-test and post-test changed from the level of potential risk users to general users. Conclusion: The current findings indicate that by considering the basic psychological needs and adaptation to college life, our program could be an effective intervention for controlling smartphone usage amongst college students. Therefore, we propose that a camp-type counseling program could be considered for application as group therapy for programs associated with preventing smartphone overdependence.

More and more non-injured operations are being implemented these days, thanks to the development of medical technology. Still, however, most operations leave direct scars on patient' bodies, as well as accompanying pain. The massage as an independent nursing intervention can stimulate the circulation of the blood of tissue and muscle and increase the relationship between a patient and a nurse. The purpose of this study is to investigate the effect of foot massage on pain in post abdominal operative patients. The nonequivalent control group, pre-post test design is used for this study. From July 7, 2000 to February 20, 2001, the 40 patients who were operated under general anesthesia in a university hospital in Seoul were studied. They were divided into two groups ; 20 patients were part of the experimental group, and the others, in the control group. In order to evaluate the effect of foot massage, severity of pain was checked with the VAS (Visual Analog Scale) and also each patients' vital signs were measured with pulse rate, systolic blood pressure and diastolic blood pressure. The collected datas were processed by SAS version 6.12 program and analyzed by the Chi-square, Fisher's exact test, t-test and repeated measures ANOVA. The results of this study were as follows. 1. The severity of pain decreased significantly in the experimental group as compared to the control group following foot massage (t=-3.317, p= .002). 2. Measured vital signs in the experimental group had more reduction of that than in the control group following foot massage. - The pulse rate in the experimental group was lower than that in the control group following foot massage (F=7.73, p=.008). - The systolic blood pressure in the experimental group was lower than that in the control group following foot massage (F=25.75, p=.000). - The diastolic blood pressure in the experimental group was lower than that in the control group following foot massage (F=15.27, p=.000). In conclusion, foot massage is an effective dependent nursing intervention for pain control of post abdominal operative patients.

Purpose: The purpose of this study was to examine the effects of interactive pictorial education on community dwelling older Korean adults' self-efficacy and knowledge for safe medication. Methods: A quasi-experimental, three-group pre- and post-intervention design was used in this study. The interactive pictorial education was designed to suit the learning patterns and psychomotor skills of older adults. The education content, dealing with safe medication, was delivered over three sessions. A total of 136 older adults from local senior centers were assigned to one of the three groups: a) interactive pictorial education plus information booklet (experimental); b) education only with information booklet (conventional); or c) no intervention (control). Results: Participants receiving interactive pictorial education had significantly higher self-efficacy (F=24.32, p<.001) and knowledge (F=24.26, p<.001) scores than the information booklet or control group at post intervention. Post-hoc analyses indicated that both the interactive pictorial and the information booklet groups had significantly higher self-efficacy and knowledge scores than the control group at the post-test point (p<.05). Furthermore, the interactive pictorial group had higher self-efficacy and knowledge scores than the information booklet group at the post-test point (p<.05). Conclusion: These results suggest that the interactive pictorial education is an innovative approach that provides a means for older adults to learn appropriate medication use to improve their own health. It empowers older adults with different literacy levels to enhance their self-efficacy and knowledge for the safe use of medication.

The purpose of this study is to determine the effect of oral vitamin C supplements on blood sugar and serum lipid level(total cholesterol, triglyceride, high density lipoprotein, low density lipoprotein) in non-insulin independent diabetes mellitus. The study design was a non equivalent control group pre-test post-test design. Data for the study were collected from June 24 to August 31, 2001. The ninty-five research subject were assigned to experimental group(51) and control group(44). Vitamin C(3g/day) was given to 51 subjects for 4 weeks. Following a 12h overnight fasting, blood sample was obstaind at baseline and at the end of 4week - supplementation. Blood samples were taken for plasma vitamin C concentration, fasting blood sugar, HbA1c and serum lipid level. The pre-equivalent test was used by Chi-squre, t-test and two group's pre and post experimental differences were analyzed by t-tset to compare with each other. The results of this study were as follows ; 1. The difference between the two groups in plasma vitamin C concentration was significant(t=-12.950, p=.000). 2. The difference between the two groups in fasting blood sugar was significant(t=5.293, p=.000). 3. The difference between the two groups in HbA1c was not significant(t=1.758, p=.082). 4. The difference between the two groups in total cholesterol, HDL, LDL was significant(t=3.786, p=.000 ; t=-5.515, p=.000 ; t= 4.169, p = .000). These results suggest that megadose vitamin C supplementation be effective in lowering fasting blood sugar, serum lipids and increasing plasma vitamin C. Thus dietary measures to increase plasma vitamin C may be on important health strategy for reducing the compliance of diabetic patients.
