The purposes of this study are to identify effectiveness of the hospital-based home care project, to manage patients' problems in comprehensive way, to decrease the patients' economical burden to the arthritis patients. The design is nonequivalent control group pretest-posttest design with matched samples in terms of age, sex and disease severity. Fifty two patients were assigned in each of the experimental and control groups in Seoul, Kyunggi, Kangwon and Kwangju. Before the experiment and after 3-month period of experiment of home care, level of pain, duration of morning stiffness, Richie Index, ADL, self-efficacy and depression were measured. Nine patients were excluded from the control group because of denial of participation. Contents of home care provided to the experimental group include distribution of prescribed drugs, assessment of patient's condition and side-reactions of drug, pain control, depression control, nutrition guide, exercise teaching, and family counselling. Patients assigned to the control group visited the outpatient clinic once a month as usual. Null hypotheses were selected because physicians concerned about the ineffective change of patients' conditions due to indirect communication with patients through nurses. Level of pain, Richie Index, ADL, self-efficacy, depression and duration of morning stiffness did not significantly different between two groups as expected. In the experimental group, level of pain, ADL, Richie Index and duration of morning stiffness changed to the positive direction from the pretest to the posttest. However, level of depression and self-efficacy did not show any changes. Ninety percent of patients in the experimental group satisfied with the home care provided to them. Since this is the intermediate report, more detailed and long-term report will be prepared.

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.

Purpose: The purpose of this study was to identify the effects of Guided Imagery on the stress and anxiety of nursing students in clinical practice. Method: The research design was a nonequivalent control group pretest-posttest design. The data were collected from the 20th of June to the 11th of July 2003. The objects of this study were 32 nursing students of college(16 for the experimental group, 16 for the control group). The instruments used in this study were State Trait Anxiety Inventory, the stress scale developed by Choi(1991). The guided imagery was provided through audiotapes to the subjects for 8 minutes, a time for 5 days. The pretest was given before the therapy to measure variables for both groups and the posttest was performed after intervention. The data were analyzed by the SAS program using t-test. Result: The results of this study are as follows. The stress scores of students were decreased in the experimental group, but were not significantly different between the experimental group and the control group after the guided imagery. The anxiety scores of students were significantly different between the experimental group and the control group after the guided imagery. Conclusion: The guided imagery can be suggested as an effective nursing intervention to reduce the anxiety. Further studies to identify the effects of stress reduction according to the frequency of the guided imagery can be needed.

Purpose: Obesity among children from low-income families is becoming a social problem. The aim of this study was to evaluate the effectiveness of an obesity prevention program that included physical activity, nutrition education, behavioral modification, and primary caregiver participation components among children from low-income families. Methods: The study analyzed a nonequivalent control group using a pretest-posttest design. A total of 77 children were recruited from six community childcare centers using purposive sampling. For the intervention group (n=40), the pretest was administered before the combined intervention program involving the participants' primary caregivers was conducted for 8 weeks. The posttest was conducted immediately after the program and again four weeks after the program. Results: Flexibility (F=4.64, p=.020), muscular endurance (F=11.22, p<.001), nutritional knowledge scores (F=4.79, p=.010), body image satisfaction scores (F=4.74, p=.012), and self-esteem scores (F=3.81, p=.029) showed significant differences and interactions between group and time for the intervention and control groups. Conclusion: Strategies to actively engage the primary caregivers of low-income families in children's obesity programs are needed. Obesity prevention programs for children based on the program in this study should be routinely developed, and continuing attention should be given to children from low-income families.

Objectives: This purpose of this study was to examine the trends in interventional research and analyze the contents and results of intervention through a systematic literature review of the domestic research literature, suggesting the effect of an oral care program on elementary school students. Methods: A total of 262 articles were retrieved initially, and the duplicate articles were then removed, excluded after screening titles, abstracts, and full-text articles. Finally, a total of 16 papers were used in the review. Results: The study included 9 articles with the nonequivalent control group pretest-posttest design and 7 with the one-group pretest-posttest design. All articles were of non-randomized studies. The most common index of the interventional effect was dental plaque. Further, oral health behaviors and knowledge, perception, self-efficacy, and DMFT index were common indices. In the quality assessment, in the "blinding of outcome assessment" among six items of ROBANS, 12 studies showed a high risk of bias. Conclusions: In order to develop an interventional oral health care program for elementary school students and evaluate the effectiveness, a strict research design and qualitative improvement of research reports are required, and continuous research should be conducted to develop a systematic protocol.
