The term thoracic outlet syndrome (TOS) is used to describe patients with compressed subclavian arteries, veins, and brachial plexuses in the region of the thoracic outlet. The objective of this study was to evaluate a scalenus stretching exercise that aims to restore normal function to patients with TOS. This study consisted of 60 patients with symptoms of TOS, and divided the patients into 3 groups: one that received manual therapy, one that practiced self stretching, and a control group. Each group consisted of 20 patients. This study assessed the efficacy of scalenus stretching exercise by examining the resting pain, tenderness, spherical grip power, and pinch grip power of patients. The data were analyzed using one-way ANOVA, Scheffe post hoc test, and independent t-test. The results showed that resting pain was statistically significant within the manual therapy and self stretching groups (p<.05), and that the resting pain of the manual therapy group was more statistically significant than that of the self stretching group (p<.05). Tenderness, spherical grip power, and pinch grip were statistically significant within the manual therapy and self stretching groups (p<.05), but there was no statistically significant difference between the two groups (p>.05). Finally I could see that there were no statistical differences between manual therapy and self stretching to improve the symptoms of the patients with TOS. These results imply that self stretching by patients is as important as manual therapy by a physical therapist.

Purpose: The purpose of this study is to examine the effect of various bridge exercises on walking ability. Method: The subjects were 30 stroke patients. They were divided into a bridge exercise group on a stable support surface (Group I), a bridge exercise group on an unstable support surface (Group II), and a bridge exercise group combined with whole body vibrations (Group III). 10 subjects were randomly assigned into each group. The subjects of this study had 30 minutes of nervous system physical therapy including gait training and strength training. In addition, each group underwent a 30 minutes session five times a week for eight weeks. Before intervention, LUKOtronic was used to measure step width and step length, time was measured with a 10 m walking test, and time and number of steps were measured with the figure 8 walking test. After the intervention, remeasured and analysis was performed for each group. Results: As a result of comparing and analyzing the change of walking ability between groups, there was a statistically significant difference. As a result of the post hoc analysis according to the change of walking ability among groups, the change of walking ability was larger in Group III than in Group I and Group II. Conclusion: Based on these results, it is confirmed that the bridge exercise combined with whole body vibration was more effective for walking ability. Based on these findings, this study proposes an effective program for elite athletes as well as stroke patients.

Objectives: The purpose of the study was to investigate the relationship between oral health perception and oral health-related quality of life-14(OHIP-14) in a geriatric hospital. Methods: A self-reported questionnaire was completed by 230 elderly people in a long-term care institution. The questionnaire was consisted of items on general characteristics, oral health perception and OHIP-14. Except incomplete answers, 226 data were analyzed statistically with one-way ANOVA, t-test, Pearson's correlation coefficient and post hoc Tukey test and ANOVA when significance was set at 0.05. Results: The OHIP-14 showed a negative linear relationship(p<0.01) of r=-0.272 with the oral health perception. Among the subgroups of the OHIP-14, quantitative linear relationship(p<0.01) was shown in functional limitation(r=0.822), physical pain(r=0.825), psychological discomfort(r=0.568), physical disability(r=0.895), psychological disability(r=0.652), social disability(r=0.804) and handicap(r=0.818). Conclusions: In order to improve the oral health perception and OHIP-14 in a geriatric hospital, it is necessary to develop continuously a variety of oral health education and systematic oral health promotion program.

This paper aims to analyze the accident based on changing patterns of traffic culture index. For this purpose, this paper particularly focuses on classifying the traffic culture patterns and developing the traffic accidents using panel count data model. The main results are as follows. First, the traffic culture patterns are divided into 'increasing', 'decreasing' and 'other' patterns. The null hypotheses that the number of accident are the same over patterns are rejected. Second, 4 fixed effect negative binomial models which are all statistically significant are developed. Third, the regions with 'increasing' pattern are analyzed to be mostly the counties, and to demand the traffic law enforcement. Fourth, the regions with 'decreasing' pattern are evaluated to be mainly the districts and to require such the traffic culture as turn signal usage. Finally, the regions with 'other' pattern are analyzed to be mostly the cities and to ask for enhancing the level of traffic culture.

Purpose: The purpose of this study was to investigate the influence of different implant computer software on the accuracy of image registration between radiographic and optical scan data. Materials and Methods: Cone-beam computed tomography and optical scan data of a partially edentulous jaw were collected and transferred to three different computer softwares: Blue Sky Plan (Blue Sky Bio), Implant Studio (3M Shape), and Geomagic DesignX (3D systems). In each software, the two image sets were aligned using a point-based automatic image registration algorithm. Image matching error was evaluated by measuring the linear discrepancies between the two images at the anterior and posterior area in the direction of the x-, y-, and z-axes. Kruskal-Wallis test and a post hoc Mann-Whitney U-test with Bonferroni correction were used for statistical analyses. The significance level was set at 0.05. Result: Overall discrepancy values ranged from 0.08 to 0.30 ㎛. The image registration accuracy among the software was significantly different in the x- and z-axes (P=0.009 and <0.001, respectively), but not different in the y-axis (P=0.064). Conclusion: The image registration accuracy performed by a point-based automatic image matching could be different depending on the computer software used.

PURPOSE. This study aimed to evaluate the marginal discrepancy of full-arch frameworks in implant-supported prostheses fabricated using pre-sintered soft alloy (PSA). MATERIALS AND METHODS. Full-arch metal frameworks were fabricated on the edentulous implant model using casting alloy (CA), fully-sintered hard alloy (FHA), and PSA (n = 4 in each group). To evaluate the misfit of the framework to the abutments, the absolute marginal discrepancy (AMD) values of the frameworks were measured in cross-sectional images that had been drawn as part of the triple-scan protocol. The AMD values were compared among the tested alloy groups using the Kruskal-Wallis test, with a post hoc Mann-Whitney U test (${\alpha}=.05$). RESULTS. The FHA and PSA groups showed lower marginal discrepancies than the CA group (P<.001). However, the FHA group did not differ significantly from the PSA group. CONCLUSION. Soft alloy milling is comparable to hard alloy milling, and it is more precise than casting in terms of the marginal fit of implant-supported, full-arch prostheses.

Purpose: The purpose of this study was to examine the levels of self-esteem and resilience and to investigate factors affecting on the resilience among nursing students. Methods: The subjects for this study were 175 nursing students and the data were collected from November 15 to December 20, 2016. The data were analyzed using t-test, ANOVA, Pearson's correlation coefficients and multiple regression. Results: Subjects' mean scores of self-esteem and resilience were 3.60 and 3.78, respectively, on a 5-point scale. There were significant differences in the level of resilience among grade (F=3.30, p<.001). The post-hoc test showed that the resilience level of the fourth-grade subjects was significantly higher than that of the third-grade. There were no significant differences in the level of resilience according to gender, religion, residence type, and economic level. Self-esteem was positively correlated with resilience (r=.80, p<.001) and economic level (r=.20, p=.007). The results of the multiple regression analysis showed that self-esteem was a significant predictor for resilience (β=.81, p<.001) which explained 64.7% of the total variance. Conclusion: Self-esteem was an significant factor for nursing students' resilience. Therefore, intervention strategies should be developed for nursing students to improve their self-esteem.
