Objectives To investigate clinical effects of needle embedding acupuncture treatments for chronic low back pain patients. Methods 30 patients with chronic low back pain were recruited and randomized into two groups-the embedding acupuncture group or the placebo. At baseline, the age, height, weight, visual analogue scale (VAS), Oswestry disability index (ODI) scores were measured. And surface electromyography (SEMG) data of both erector spinae at L2, L4 level were also measured on both groups and asymmetry index (AI) were calculated. The embedding or placebo acupuncture treatment was performed on the erector spinae according to SEMG values; immediately after the first evaluation and 48 hours after the first visit. After 96 hours of intervention, the VAS, ODI score and SEMG of both erector spinae were measured again. Statistical significance was determined using the Wilcoxon signed ranks test or the Wilcoxon rank sum test. Results The mean VAS, ODI score after treatment was decreased significantly compared with baseline on both groups. And the VAS, ODI score and AI of the embedding acupuncture group was more decreased significantly than the placebo (p<0.05). Conclusions The results suggest that embedding acupuncture for chronic low back pain patients was effective on the VAS pain score, ODI score and AI of the erector spinae.

Objectives The purpose of this study is to compare the effects of ultra sound (U/S) and chuna on lumbago by meridian muscle electrography (MMEG). we performed U/S and chuna on erector spinae muscle. Methods This study was carried out on 20 lumbago patients. 20 patients were divided into U/S group and chuna group. U/S group take treatment 5 minutes. Chuna group take treatment 10 minutes. After performing U/S and chuna treatment 6 times, we compared both in terms of VAS, ODI, ROM, root mean square (RMS) and special edge frequency (SEF) on erector spinae muscle. The effect of each treatments are compared by Wilcoxon's signed rank test. The difference of effect between both groups are compared by Wilcoxon's rank-sum test. Results 1. Both U/S group and chuna group showed significant improvement in VAS and ODI after treatment. 2. U/S group showed insignificant improvement in both RMS and SEF. 3. Chuna group showed significant improvement in SEF at left lower point and RMS at left upper point. 4. Both U/S group and chuna group showed insignificant improvement in ROM. 5. There are no significant differences between both groups except SEF at left upper point. Conclusions According to above results, we found out that performing U/S or chuna on erector spinae muscle has effect in terms of VAS and ODI. But, in terms of SEF, we found out different result for both side. And we can't found out effect in terms of RMS and ROM of L-spine.

One of the difficulties of female-headed families face is economic hardship. Low-income single mothers work long hours, become isolated and feel burdened for dual roles. And many of them don't have relatives to share parenting roles. As a result, children of low-income female-headed families are easy to be neglected and left to form a delinquency-prone group in neighborhood. Traditionally, it has been viewed that children in female-headed families have problems due to the loss of father role. However, study indicates that these children can adjust well if the relationship between mothers and children is consistent and adequate. An Intervention program for low-income female-headed elementary children was developed and delivered in two community social welfare centers. The purpose of the program is to raise self-esteem. Two goals were 1) management of daily living habits and 2) improvement of family relations. Social workers maintained contact with mothers to talk about children's behaviors and to prompt hugging and touching. In addition, workers helped children to form good relationships with peers and school teachers. Children were satisfied with the program. Their family relations were improved statistically significantly after the program(wilcoxon signed rant test z=-2.934 p<.05). However, their self esteem were not improved significantly (wilcoxon signed test z=-1.173 p>.05). Qualitative analysis of each children were also discussed. The implications of the study are the followings: Intervention programs need to be delivered separately for low-grade and high grade elementary children because they have different developmental needs. The program also need to include education on sex and marriage as well as aggression reduction. Society needs to provide more support to single mothers for their personal and parenting needs.

This study is to investigate the effect of lower extremity strength exercise using biofeedback system on community-based elderly. Ten community-based elderly were exercised using the biofeedback system (with functional electrical stimulation) three times a week for six weeks. Data analysis was performed using Wilcoxon signed rank test. Physical function improved significantly, but there was no significant difference in muscle strength and muscle mass. Although elderly people were able to confirm that community-based ICT home biofeedback training could be possible and could lead to improvements in the lower extremity function, further research is needed to demonstrate a clearer effect by expanding the target population, distinguishing the sexes, and providing a personalized training method.

PURPOSE. One of the most important factors in evaluating the quality of fixed dental prostheses (FDPs) is their gap. The purpose of this study was to compare the marginal and internal gap of two different metal-ceramic crowns, casting and selective laser sintering (SLS), before and after porcelain firing. Furthermore, this study evaluated whether metal-ceramic crowns made using the SLS have the same clinical acceptability as crowns made by the traditional casting. MATERIALS AND METHODS. The 10 study models were produced using stone. The 20 specimens were produced using the casting and the SLS methods; 10 samples were made in each group. After the core gap measurements, 10 metal-ceramic crowns in each group were finished using the conventional technique of firing porcelain. The gap of the metal-ceramic crowns was measured. The marginal and internal gaps were measured by two-dimensional and three-dimensional replica techniques, respectively. The Wilcoxon signed-rank test, the Wilcoxon rank-sum test and nonparametric ANCOVA were used for statistical analysis (${\alpha}$=.05). RESULTS. In both groups, the gap increased after completion of the metal-ceramic crown compared to the core. In all measured areas, the gap of the metal cores and metal-ceramic crowns produced by the SLS was greater than that of the metal cores and metal-ceramic crowns produced using the casting. Statistically significant differences were found between cast and SLS (metal cores and metal-ceramic crown). CONCLUSION. Although the gap of the FDPs produced by the SLS was greater than that of the FDPs produced by the conventional casting in all measured areas, none exceeded the clinically acceptable range.

The purpose of this study was to examine the effects of student-generated questions (SGQs) partially applied in a pathology course on learning motivation, communication abilities, and problem-solving skills in nursing students. A one-group pretest-posttest design was employed to conduct this study with 106 nursing students taking the pathology course in a university-setting. Data were analyzed using a Wilcoxon signed-rank test in SPSS version 20. The results showed that communication and problem-solving skills were significantly improved at the end of the semester compared to the beginning. The findings imply that SGQs could be an effective means to improve nursing students' skills of communication and problem solving. To equip nursing students with such core competencies, teaching-learning methods combined various strategies should be developed and applied to nursing education.

Background: Physician behaviors that undermine a culture of safety have gained increasing attention as health-care organizations strive to create a culture of safety and reduce medical errors. We developed, implemented, and assessed a course to teach physicians skills regarding effective coping and interpersonal communication skills and present our results regarding outcomes. Methods: We examined a professional development program specifically designed to address unprofessional or distressed behaviors of physicians, and we evaluated the impact on burnout, quality of life, and emotional flooding scores of the physicians. Assessments of burnout, quality of life, and emotional flooding were assessed preintervention and postintervention. Results: Results demonstrated statistically significant reductions over time in physicians' emotional flooding and emotional exhaustion (EE). Specifically, using a Wilcoxon Signed-Rank test, results revealed that flooding scores at follow-up were statistically significantly lower than at baseline, V = 590, p < 0.05, and EE and personal accomplishment distributions were found to significantly deviate from normal as indicated by Shapiroe-Wilks tests (p < 0.05). A Wilcoxon signed-rank test indicated that EE scores were significantly higher at baseline compared to follow-up 1, V = 285, p < 0.05. Conclusion: We conclude that the physician participants who enrolled in the educational skills training program improved scores on emotional flooding and EE and that this may be indicative of improved skills related to their experiences and learning in the program. These improved skills in physicians may have a positive impact on the overall culture of safety in the health system setting.
