Purpose: This study examined the effect of vibration exercise on the thickness of the oblique extrinsic, oblique abdominal, and biceps muscles, which are trunk muscles, targeting children with spastic cerebral palsy. Methods: The participants in this study were 20 children (8 male and 12 female) with cerebral palsy aged 5-10 years. They were classified into two groups using a randomized allocation method, and the trunk muscle thickness was measured using an ultrasound-imaging device before and six weeks after the experiment. A paired t-test was used for the within-group changes, and an independent t-test was used for the inter-group changes. The significance level was set to α=0.05. Results: There was a significant increase in the inter-group change in the experimental group and control group in the intra-group change in the external oblique muscle and internal oblique muscle. After six weeks, there was a significant increase in the experimental group compared to the control group. Conclusion: Vibration exercise had a positive effect on the trunk muscle thickness of children with cerebral palsy. Vibration exercise produced a significant difference in the changes in the trunk muscle thickness in children with cerebral palsy compared to no vibration exercise. These results may provide basic data for future research and as a training method for strengthening the trunk muscles in clinical trials.

Purpose: To provide an in-depth analysis of the physical changes in and marital experiences of immigrant women in Korea, considering the differences in their cultural backgrounds. Methods: A qualitative research methodology with a phenomenology perspective was used. Data were collected through interviews from four focus groups and through in-depth interviews from five individuals. Data analysis was carried out using Colaizzi's phenomenological analysis method. Results: Twenty-four participants from nine different nations were interviewed. Three phenomenological theme clusters were identified and six sub-themes were derived. These comprise: "emergence of physical changes", "experienced symptom with negative result", and "coping with my body". The derived themes comprise: "struggling for my body to survive", "changed body after pregnancy and delivery", "diagnosed as normal but", "neglected my health", "using familiar care", and "unfamiliar health service system". Conclusion: Immigrant women by marriage in Korea are new subjects of nursing care. Their physical changes and experiences in coping with marriage at an early stage of immigration as described by themselves provide valuable information for nursing professionals. Cultural differences, problems specific to women, and our social conditions regarding minorities and our patriarchal tradition that discriminates against women affect their health problems. We strongly recommend that nurses should actively determine and engage in the health problems of immigrant women.

PURPOSE: The aim of this study is to compare changes in the thickness of the gluteus medius muscle fiber between chronic low back pain(clbp) with gluteus medius weakness and healthy subject. METHODS: Ultrasound imaging was used to measure in the thickness of each fiber of the gluteus medius muscle based on maximal muscle contraction during abduction motion of the hip joint in a healthy group (11 subjects) and a chronic CLBP group (21 subjects). An independent t-test was performed to analyze the difference of thickness in each fiber of the gluteus medius muscle and the rate of changes in the fibers in the two groups. RESULTS: The fiber thickness changes in the gluteus medius muscle were significantly lower for the posterior fiber in the CLBP group compared to the healthy group (p<0.01). The changes in rate of difference of thickness the posterior part of the gluteus medius muscle was significantly lower in the CLBP group than in the healthy group (p<0.05). CONCLUSION: The findings of this study CLBP patients with weakness of the gluteus medius muscle that lower for the posterior fiber's difference of thickness and rate of change in the CLBP group compared to the healthy group. Indicate that rehabilitation of CLBP patients with weakness of the gluteus medius muscle should consider the functions of posterior fiber of the gluteus medius muscle.

Background: Studies suggest that induced emotional changes can affect the sensory-motor system involved in the practice of muscle activity and movement in physical aspects. Previous studies have shown focused on effects just feedback on muscle activity associated with emotions but rarely have focused induced emotional change on gross motor function such as muscle activity. Objects: The purpose of this study was to compare biceps activity and emotion that before and after viewing a video was induced positive or negative emotion. Methods: The study enrolled 34 healthy male and female who scored at normal points on the Center for Epidermiological Studies-Depression Scale. The study measured over two weeks, showing subjects pleasant and sad videos one by one in a week. We performed to measure the biceps brachii activity which is maximal voluntary isometric contraction (MVIC) and the visual analog mood scale (VAMS) scores before and after one week. The significance level was set to α = 0.05. Results: There was no significant difference in muscle activity of the biceps brachii before and after each video was viewed (p > 0.05). However, the visual analogue mood scale showed an increase in VAMS after viewing each video (p < 0.05). Conclusion: We figured out induced emotional changes are cause actual emotional changes but there are no differences in muscle activity. In this research, watching the video with a short time looks like insufficient to change muscle activity. Nevertheless, there might be different when we check various muscles with sufficient time for viewing the video. Further study is needed to measure a variety of muscles with more time for viewing the video.

The effects of Proprioceptive Neuromuscular Facilitation (PNF) and elastic band exercise on the physical functions and blood lipids of obese elderly women were investigated. The experimental group ($n_1=16$) patients underwent PNF for 12 weeks, and the control group ($n_2=15$) patients performed elastic band exercises. SPSS 21.0 was used to compute the means and standard deviations. After the 12-week PNF, both the experimental and control groups showed statistically significant differences in the physical functions (cardiovascular endurance, strength of the lower extremity, muscular endurance, flexibility, balance, and agility) (p<.05), but the difference in the experimental group was more significant than that in the control group (p<.05). In terms of the changes in the blood lipid levels (total cholesterol, triglycerides, high-density lipoprotein, and low-density lipoprotein), the experimental group showed significant changes (p<.05). In conclusion, PNF was confirmed as more effective than elastic band exercise in improving the physical functions and blood lipid levels of obese elderly women.

The purpose of this study was to investigate the effect of 8 weeks of forestry exercise on the quality of life and physical self-concept of breast cancer survivors. The subjects of this study were eight breast cancer survivors 6 months after mastectomy. The forest combined exercise program consisted of aerobic exercise through forest walking and resistance exercise using elastic bands. The forest combined exercise was conducted twice for 8 weeks. Forest trekking consisted of a 2km walking speed and resistance exercise consisted of three levels of sets and intensity. The format was divided into gradual increases. The exercise time was 40 to 60 minutes for forest trekking, 20 to 30 minutes for descent, and 40 to 60 minutes for resistance exercise, for a total of 120 to 130 minutes per day. Breast cancer survivors' quality of life was measured using a questionnaire, and changes in quality of life were measured using a t-test (α=.05). Physical self-concept was assessed through in-depth interviews. There was no statistically significant difference in quality of life before and after 8 weeks of combined forestry exercise, but there was a slight tendency to increase in the area of physical well-being. Physical self-concept showed positive changes in motivation, physical strength improvement, health promotion, physical competence, and self-confidence through the forest composite exercise. Therefore, the forest composite exercise is believed to have a positive effect on the physical self-concept of breast cancer survivors.

Purpose : The purpose of this study was to analyze skin reactions induced by ultraviolet irradiation using digital imagery. Methods : We recruited 15 women and ultraviolet irradiation was applied to their lumbar area. (The degree of inflammatory reaction was set on the basis of the third erythema dose. Image analysis was divided by Photoshop CS (8 bit RGB scale and gray scale). Then, images were processes using Image Pro Plus 4.5 program analyzing R, G, B, chromatic red value, luminance value and gray value. Results : As a result of analyzing changes in RGB scale, there were statistically significant differences in R, G, and chromatic red values. As a result of analyzing changes in gray scale, there were statistically significant differences in gray value. Analysis of changes in B and luminance values showed that there was no statistically significant difference. Conclusion : This study found that ultraviolet irradiation had influence on RGB and gray scale. These results suggest that changes to digital images on skin reaction by ultraviolet irradiation are related to erythema. In particular, these changes are related to R and gray values.
