  • This study was intended to investigate the effects of regular swimming exercise and vitamin C supplementation on the antioxidant system following exercise stress. For the swimming exercise experiment, a swimming adaptation exercise of 1 week was given to a group of 6-week-old mice. Following this, a swimming exercise for 8 weeks was conducted. The experimental group was divided into 3: a control group (C), a swimming exercise trained group (T), and a group of swimming + vitamin C supplementation (TC: vitamin supplementation: 1.3 mg/l00 g diet). After the swimming exercise, these group were further divided into those that had received the exercise stress for 2 hours and those that had not experienced exercise stress group. Then, the activities of the superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and malondialdehyde (MDA) concentrations were measured. There was a lower weight increase in the T and TC groups than in the C group, and there was no significant difference between T and TC group. When exercise stress was not experienced, the activity of SOD was significantly increased in the TC group than in the T group, but there was no significant difference between C and T groups. The groups that had experienced a 2-hour exercise stress showed the SOD activity levels according to the following order, C < T < TC, with a significant difference between the three groups (p<0.05). There was no difference in MDA concentration amongst the experimental groups in non-exercise stress group. As well, there was no differences in MDA concentration between the C group and T group in the 2 hour exercise stress group. However, the TC group showed a MDA concentration level significantly lower than that of the T group. A significant increase in MDA concentration was observed in C group, when exercise stress was provided with no significant difference in the T and TC groups. As a result, regular exercise and vitamin C supplementation can be considered important in controlling the formation of lipid peroxides in exercise stress.

  • Effectiveness of the video-record learning method in teaching bowel elimination nursing skill was investigated using an experimental research methodology. Data was collected from 63 female students attending Fundamental Nursing class from a nursing college in Seoul. The subjects were randomly assigned to two groups, one is the experimental group of 29 and the other the control group of 34. The independent variable was video-record learning method and the dependent variable were the degree of knowledge achivement, nursing skill achivement, competence on practicing elimination skill, and satisfaction about the learning method. The hypotheses of the study were as following. 1) There will be significant difference between the experimental group and the control group in dependent variables. 2) There will be significant positive correlations between nursing skill achievement and other three dependent variables-interest in nursing, adaptation in nursing, and preference of nursing job. Data was analyzed using descriptive statistics, chi-square test, t-test, and Pearson's correlation coefficient with SPSS $PC^+$ program. Findings of the study are : 1) There was no significant difference between the experimental group and the control group in knowledge achievement using P<.05. 2) There was significant difference between the experimental group and the control group in nursing skill achievement using P<.05. 3) There was no significant difference between the experimental group and the control group in competence on practicing elimination skill using P<.05. 4) There was no significant difference between the experimental group and the control group in satisfaction about learning method using P<.05. 5) There was positive correlation between nursing skill achievement and the other variables but no significant difference was shown. 6) This study suggests that video-record learning method is an effective learning method for achiving basic nursing skills but is not effective in other areas such as knowledge achivement, competence in performing nursing practice, and satis-faction about the learning method. Further study with more developed research design and statistical analysis should be done to investigate the effectivenes of video-record learning method in learning basic nursing skill more accurately.

  • This study was designed to investigate the effect of vibratory stimulation on recovery of muscle function from delayed onset muscle soreness (DOMS). Volunteers performed 3 set of 70 % maximal voluntary eccentric muscle contraction and induced DOMS. volunteers were allocated to one of three treatment group after DOMS : group I (control), group II (ultrasound), group III (vibration). Maximal Voluntary Isometric Contraction (MVIC), Visual Analog Scale (VAS), Range Of Motion (ROM), Root Mean Square (RMS), Median frequency (MDF), Blood Serum Creatine Kinase (CK), Lactic dehydrogenase (LDH) were recorded at baseline, and 24, 48, 72 hours post-exercise. In MVIC measurement, there was a statistically significant difference in group III compared to group I (p < .05). In VAS measurements, there were a statistically significant difference in group II and III compared to group I (p < .05). In ROM measurement, there was a statistically difference in group II and III compared to group I (p < .05). In Muscle Volume with Ultrasonography measurement, there was no statistically significant difference in any groups (p > .05). In RMS and MDF measurement, there were a statistically significant difference in group II and III compared to group I (p < .05). In Blood samples of CK and LDH measurements, There were no statistically significant difference in any groups (p > .05). From the above result, Vibratory stimulation had a positive effect on recovery of muscle function from delayed onset muscle soreness. Further studies should be undertaken to ascertain the more effectiveness of vibratory stimulation and may be a promising treatment modality.

  • 66 patients with low back pain were evaluated to determine if any differences of weight bearing were existed between the same side leg that feel pain(pain side leg) and that without pain (non-pain side leg) of lower extremities while weight bearing. 66 patients were divided into 3 groups according to pain pattern such as low back pain only(26), radiating pain only(21) and low back pain with radiating pain (19). Control group were 28 normal persons. The weight bearing was rated by Limloader(Model LLD-2000, Ver 1.2) and analyzed by paired and independent t-test, one-way ANOVA, Dunan's analaysis and Pearson's correlation analysis. The results of this study were as follows : 1. In patient group, significant difference of weight bearing rating between pain side leg and non-pain side leg was found. There was borne significantly less weight bearing rating(14.68%) on the pain side leg(P<.001). 2. In normal group, there was no significant difference between left and right leg(P>.05). But there was significant difference(3.21%) in absolute difference of both leg(p<.001). 3. The difference of 1 and 2 was 11.47% : more difference of weight bearing rating between both legs in patient group than that of the control group(p<.001). 4. There were significant differences of weight bearing rating in those 3 groups : low back pain group(10.30%), radiating pain group (17.90%) and low back pain with radiating pain group (17.10%) (p<.001). 5. There was significant correlation between pain intensity and difference of weight bearing rating(p<.05). The severer pain intensity. the more difference of weight bearing rating was found. 6. There was no significant correlation between the age, height and duration of symptom, etc(p>.05).

  • Human body balances right and left leg centering around pelvis and spine. Therefore, imbalance of lower extremity means disequilibrium of the body. The difference of lower extremity length can cause a number of clinic symptoms including scoliosis, low back pain, sacroiliac pain, and sports injury. In this study, we tried to analyze low back pain and joint stiffness resulting from the difference of lower extremity length. The subjects were 80 male students who are 20-25 years old. The results of this study were as following: 1. Low back pain depending on the difference of lower extremity length One group which the difference of lower extremity length is above 12mm showed average different length as 18.0mm, the other group which one is below 12mm showed as 6.3mm. A group of above 12mm had more severe low back pain than a group of below 12mm. 2. Joint stiffness depending on the difference of lower extremity length A group of above 12mm had more severe joint stiffness than a group of below 12mm.
