Equivalence of the filament and overlap graphs of subtrees of limited trees

The overlap graphs of subtrees of a tree are equivalent to subtree filament graphs, the overlap graphs of subtrees of a star are cocomparability graphs, and the overlap graphs of subtrees of a caterpillar are interval filament graphs. In this paper, we show the equivalence of many more classes of subtree overlap and subtree filament graphs, and equate them to classes of complements of cochordal-mixed graphs. Our results generalize the previously known results mentioned above

The Effects of Treadmill Walking on Gait Parameters in Individuals with Dementia with Lewy Bodies

Background: Individuals with dementia with Lewy Bodies (DLB) exhibit motor impairments similar to those seen in Parkinson’s disease (PD), including gait disturbances, thus increasing their risk for falls. While research suggests that treadmill training is a successful treatment modality in PD, our current study is the first to investigate its effects in the DLB population. The purpose of this study was to investigate the safety, feasibility, and effects on gait of a single 20 minute session of treadmill walking (TW) in individuals with DLB. We hypothesized that TW would improve gait velocity, and spatial and temporal gait parameters. Methods: This study utilized a one group pre-test/post-test design with ANOVA analysis. Eight individuals with a diagnosis of DLB underwent the 20 minute TW intervention. Spatiotemporal gait parameters in forward, forward fast, and backward walking were assessed with GAITRite before and after the intervention. Results: No abnormal HR or BP responses were observed during the intervention or testing. No adverse events occurred. Seven of eight (87.5%) participants were able to complete the TW and testing; 4 participants achieved their comfortable overground walking speed on the treadmill. There were significant improvements in temporal gait measures of comfortable walking post-TW. For example, we found an increase in stride velocity (71.22 ± 19.45 cm/s to 79.68 ± 23.43 cm/s; P = 0.028), a decrease in stance time (0.83 ± 0.04 s to 0.78 ±0.04 s; P = 0.006), and a decrease in double support time (0.47 ±0.05 to 0.43 ± 0.06; P = 0.012) post-intervention. There were no significant changes in spatiotemporal measures of backwards and fast walking gait parameters. Conclusions: This study demonstrates that TW is safe and feasible in individuals with DLB. All subjects improved on velocity and the majority of temporal parameters of gait exclusively in comfortable walking, suggesting that the benefits of TW may be task specific. Pace training on a treadmill with multiple sessions may be a beneficial intervention for individuals with DLB.The Mangurian Family FundA three-year embargo was granted for this item.Academic Major: Health Sciences Progra

Objects of Attraction

The work in Objects of Attraction is a culmination of the skills and experiences that I have acquired while at Georgia Southern University. The pieces are abstractions of natural flowers and seedpods that stem from my experiences in South Georgia woods. These brightly colored ceramic works are a reflection of the joy and wonder that I receive from the natural world. Colors, textures and forms found in nature are the driving force behind my work; I feel that so many of these natural attributes are often ignored. By creating work based on nature I strive to inspire viewers to take a second glance at the phenomenal beauty that the natural world has to offer. If I can have viewers enjoy my work perhaps they can identify with a particular memory or experience that helps them appreciate some of the smallest yet most important aspects of our world. With the fragile state of our environment, it is my intention that Objects of Attraction might play a small part in bringing awareness to the beauty that we so often destroy

The Effect of Mirrors on Body Image in Dance Majors

Mirrors cause long lasting damage to dancers, so the research being proposed is to discern the effect of mirrors on body image in freshman dance majors. This research proposal was derived from many other studies done on this topic, however those studies were focused on beginning ballet or modern dancers instead of more experienced dancers and various styles. The research will be conducted over two consecutive semesters, equaling one school year. Each semester, the dancers will either have use of the mirror or no use of the mirror and will be questioned three times throughout the semester in each dance class on how their body image has changed. The results are expected to be similar to the results of other studies, where body satisfaction will decrease when mirrors are present, but the results may very due to having experienced dancers and the possibility of males participating
