Purpose: This study was to investigate the perception of the myopia in early school-aged children's mother and develope myopia preventive education program. Method: Data was collected from June 1th to 24th, 2003. The sample group(two elementary schools in A city)consisted of 105students mother with normal vision(naked vision 1.0 or more), 105 students mother with subnormal vision(0.7 or less). The data was analyzed using S.A.S. For the test of homogeneity and significance of variable, Fisher's Exact test and Student's t-test were used. Results: 1. There was significant difference in perception of being changed the children's eyesight between normal and myopia group(t=7.86, p=.0492). 2. High scores of cause of myopia were distance from TV or computer to viewer and time of watching TV or using computer in both groups. 3. There was significant difference in perception score of cause of myopia in the myopia group was 13.26, and 18.04 in the normal group(t=3.01, p=0.003). Especially in the unbalanced and regulated diet, regulated exercise, distance of eyes reading books and illumination, normal group had more perception score than myopia group. Conclusion: A myopia education program for children and parents should be planed and the effect be verified.

Purpose: The purpose of this study was to compare self-care behavior, diabetes-related stress and stress coping style among 3 blood glucose control groups (good, inadequate, and poor blood glucose control groups). Methods: Participants were 102 type 2 diabetic patients (good group: 41, inadequate group: 31, poor group: 30). Data were collected from Feb 19 to Mar 24, 2010 and were analyzed using Chi-square, Fisher's exact test and ANCOVA with SPSS/WIN 12.0. Results: Using ANCOVA with frequency of admission, and illness duration as covariates, significant differences were found among the 3 groups in self-care behavior (total score) and the exercise subscale. Using ANCOVA significant differences were found among 3 groups in diabetes-related stress (total score), emotional burden subscale and regimen distress subscale. Using ANCOVA no difference in stress coping was found among the 3 groups, but there was a significant difference in the problem-oriented coping subscale. Conclusions: Self-care behavior, diabetes-related stress, and stress coping style are factors influencing blood glucose control. The results of this study suggest that for improving blood glucose control, self care education program focused on diet and exercise in addition to stress management program for promoting problem oriented coping capability are recommended.

Purpose: The purpose of this study was to investigate the effect of aromatherapy on pain, depression, and feelings of satisfaction in life of arthritis patients. Method: This study used a quasi-experimental design with a non-equivalent control group, pre-and post-test. The sample consisted of 40 patients, enrolled in the Rheumatics Center, Kangnam St. Mary's Hospital, South Korea. The essential oils used were lavender, marjoram, eucalyptus, rosemary, and peppermint blended in proportions of 2:1:2:1:1. They were mixed with a carrier oil composed of almond (45%), apricot(45%), and jojoba oil(10%) and they were diluted to 1.5% after blending. The data were analyzed using an 2-test, Fisher's exact test, t-test and paired t-test. Result: Aromatherapy significantly decreased both the pain score and the depression score of the experimental group compared with the control group. However, aromatherapy didn't increase the feeling of satisfaction in life of the experimental group compared with the control group. Conclusion: The result of this study clearly shows that aromatherapy has major effects on decreasing pain and depression levels. Based on our experiment's findings, we suggest that aromatherapy can be a useful nursing intervention for arthritis patients.

Purpose: This study determined the effect of head and neck massage on anxiety, pain, and discomfort for hysterectomy patients. Methods: Subjects consisted of 48 hysterectomy patients at K hospital. Experimental group (n=23) received head and neck massage at 8 minutes per massage for five times: (at admission, before sleeping on preoperative day, at 4 hours after operation, before sleeping on operation day, before sleeping on the first postoperative day). Control group (n=25) received conventional treatment. As an effectiveness of this intervention, state of anxiety and BP was measured before sleeping on preoperative day. Pain and discomfort were measured before sleeping on the day of surgery and then on the first postoperative day. Data was analyzed descriptive statistics using $x^2$ test, Fisher's exact test, paired t-test, unpaired t-test, repeated measures ANOVA and Bonferroni multiple comparison. Results: 1. State of anxiety score and BP at post-treatment decreased significantly in the experimental group. 2. Pain score in experimental group was lower than that in control group, with no significant difference; whereas, 3. Discomfort level decreased significantly in the experimental group. Conclusion: Results indicate that head and neck massage could be an effective intervention for reducing preoperative anxiety and postoperative discomfort in hysterectomy patients.

Purpose: The purpose of this study was to identify the effects of sex education on middle school boys' perception about obscene materials and self identity. Methods: This study was employed, using pretest-posttest of nonequivalent control group design. Data were collected from April 1st to May 14th, 2005. The subjects were recruited from two middle boys' school in Incheon which have similar class accomplishments and financial statues. Sampling method was used 70 students were assigned to experimental group and 74 students to control group. The 45 minutes sex education was given 4 times within 3 weeks to the experimental group. Four weeks later after education has finished, post test was done. The data were analyzed using Chi test, Fisher's exact test and t -test by SPSS. Results: The 1st hypothesis 'The experimental group which received sex education will have a higher score of perception about obscene materials than control group' was supported(t = 3.370, p = .001). The 2nd hypothesis 'The experimental group which received sex education will have a higher score about self identity than the control group' was supported(t = 1.997, p = .048). Conclusion: This study showed that sex education effectively helps middle school boys to have right perception about obscene materials and to promote self identity.

Purpose: This study aimed to identify pain, disability, anxiety, depression and educational needs between acute and chronic low back pain groups. Methods: A total of 153 patients aged 18 to 64, recruited from S-neurosurgical clinic for low back pain in Gyeonggi-do. Out of 153 subjects, 70 were Acute Low Back Pain (ALBP) group and 83 were Chronic Low Back Pain (CLBP) group. The collected data was analyzed using the SAS System V 9.4 program by chi-square test/Fisher's exact test and t-test. Results: The pain and disability scores were higher in ALBP group while the depression score was higher in CLBP group. The educational needs score in the area for the time for lumbar operation was higher in CLBP group. In the Low Back Pain (LBP) treatment management, ALBP group visited clinic (60.0%) most frequently and CLBP group visited both clinic & traditional medicine (66.3%) regularly. Conclusion: In order to minimize the progression from acute to chronic LBP, it is necessary for patients who visited the clinic to be accompanied with an education program that reflects educational needs of patients and with proven alternative therapy.

Objective : By conducing a review of clinical outcomes for patients with aneurysm treated using current microneurosurgical techniques and intensive care unit management, we speculated that grading systems based only on clinical condition or CT finding after admission failed to provide a significant stratification of outcome between individual grades of patients, because these systems did not include the factor for postoperative vasospasm. We hypothesized that postoperative blood flow velocity could have a significant impact on outcome prediction for patients surgically treated for intracranial aneurysms. Methods : We conducted a analysis on patient- and lesion-specific factors that might have been associated with outcome in a series of 55 aneurysm operations performed with measurements of blood-flow velocity with transcranial Doppler ultrasonography(TCD). In the new scale(NS) score system, 1 point is assigned additionally for the case with Hunt and Hess(H-H)/World Federation of Neurological Surgeons(WFNS) Grade IV or V, Fisher Scale(FS) score 3 or 4, aneurysm size greater than 10mm, patient age older than 60 years, blood-flow velocity higher than 120cm/sec, and posterior circulation lesion. By adding the total points, a 6-point scale score(score 0-6) is obtained. Results : Age of patient, size of aneurysm, clinical condition(H-H grade and WFNS), FS score, and blood flow velocity(TCD 1day after operation) were independently and strongly associated with long-term outcome. When NS scores were applied to 55 patients with at least 6 months follow-up, the correlation of individual scores with outcome was strongly validated the retrospective findings. Conclusion : It was speculated that TCD could be used to assess postoperative vasospasm and to monitor noninvasively the patients with aneurysmal SAH. This NS score system is easy to apply, divide patients into groups with different outcome, and is comprehensive, allowing for more accurate prediction of surgical outcome.
