Analysis Of Gait Characteristics In Mentally Handicapped Individuals, Prakriti Parijat, Jian Liu, Thurmon E. Lockhart, Courtney Haynes
Jian Liu
Physical and motor dysfunctions in mentally handicapped individuals predispose them to a higher risk of slip and fall accidents. It is estimated that over 60 million people are currently suffering with some level of developmentally related cognitive impairment (American Disability Act ADA, 2000). Mental retardation occurs in 2.5-3% of the general population. About 6-7.5 million mentally retarded individuals live in the United States alone (ADA, 2000). Slip induced fall accidents are a primary source of injury in people with mental retardation (MR). Often, the incidence of falls among this population is compounded by other disabilities such as autism, seizure, and …

Ransomware In Healthcare Facilities: The Future Is Now, Nikki Spence, David P. Paul Iii, Alberto Coustasse
Alberto Coustasse, DrPH, MD, MBA, MPH
Cybercriminals have begun to target the healthcare industry with a type of malware called ransomware, malware that encrypts an infected device and any attached devices or network drives. After encryption, cybercriminals demand a sum of money, also known as a “ransom,” to release the devices from encryption. Without adequate disaster recovery and backup plans, many businesses are forced to pay the ransom. The purpose of this study was to determine the extent of recent ransomware infections in healthcare settings, the risk liabilities and cost associated with such infections, and to determine possible risk mitigation tactics. Financial costs associated with business …

Emg And Kinematic Responses To Unexpected Slips After Slip Training In Virtual Reality, Prakriti Parijat, Thurmon E. Lockhart, Jian Liu
Jian Liu
The objective of the study was to design a virtual reality (VR) training to induce perturbation in older adults similar to a slip and examine the effect of the training on kinematic and muscular responses in older adults. Twenty-four older adults were involved in a laboratory study and randomly assigned to two groups (VR training and control). Both groups went through three sessions including baseline slip, training, and transfer of training on slippery surface. The training group experienced 12 simulated slips using a visual perturbation induced by tilting a VR scene while walking on the treadmill and the control group …

Corinne M. Daprano
The Girl Scout Wall (GS Wall) project was implemented in two classes at the University of Dayton (UD): a Mechanical and Aerospace Engineering (MAE) course, and a Health and Sports Science (HSS) course, and Sport Facility Management. The MAE course, Introduction to Materials, is a three-credit, third-year required course where students learn about the basic structure and properties of materials as well as the principles of material selection. The Sport Facility Management course is a three-semester hour, required HSS course where students are introduced to the processes of planning, constructing, equipping, maintaining, and managing sport facilities.
Hispanic Maternal And Children's Perceptions Of Neighborhood Safety Related To Walking And Cycling, Norma Olvera, Dennis W. Smith, Chanam Lee, Jian Liu, Jay Lee, Stephanie Kellam, Jun-Hyun Kim
Hispanic Maternal And Children's Perceptions Of Neighborhood Safety Related To Walking And Cycling, Norma Olvera, Dennis W. Smith, Chanam Lee, Jian Liu, Jay Lee, Stephanie Kellam, Jun-Hyun Kim
Jian Liu
This study examined neighborhood safety as perceived by children (mean age=10 years) and their mothers, and its association with children's physical activity. For all eight safety items examined, children perceived their environment as less dangerous than mothers (p<0.05). None of the multiple regression models predicting children's physical activity by safety perceptions were significant (p>0.10). The maternal perception model explained the highest percentage of variance (R2=0.26), compared to the children's perception model (R2=0.22). Findings suggest that future studies should explore relations between self-reported and objectively measured safety barriers to Hispanic youth walking and cycling.

Local Dynamic Stability Associated With Load Carrying, Jian Liu, Thurmon E. Lockhart
Local Dynamic Stability Associated With Load Carrying, Jian Liu, Thurmon E. Lockhart
Jian Liu
Objectives: Load carrying tasks are recognized as one of the primary occupational factors leading to slip and fall injuries. Nevertheless, the mechanisms associated with load carrying and walking stability remain illusive. The objective of the current study was to apply local dynamic stability measure in walking while carrying a load, and to investigate the possible adaptive gait stability changes. Methods: Current study involved 25 young adults in a biomechanics research laboratory. One tri-axial accelerometer was used to measure three-dimensional low back acceleration during continuous treadmill walking. Local dynamic stability was quantified by the maximum Lyapunov exponent (maxLE) from a nonlinear …

Slip-induced fall accidents have been recognized as a serious threat to the health of the elderly.The objective of the current study was to investigate the aging effect on the biomechanical reactions of both perturbed foot and unperturbed foot to the unexpected slips. Nineteen younger (mean age: 25.0 years old) and twenty-one older (mean age: 71.2 years old) adults were involved in a laboratory study,in which slippery surface was induced during walking without their awareness.The reactive responses of both slipping foot and unperturbed foot were quantified by optical motion capture system and force platforms.The results indicate a characteristic toe-touch strategy by …

BACKGROUND: Duchenne muscular dystrophy (DMD) is a severe neuromuscular disease that affects 1 in 3500 boys. The disease is characterized by progressive muscle degeneration that results from mutations in or loss of the cytoskeletal protein, dystrophin, from the glycoprotein membrane complex, thus increasing the susceptibility of contractile muscle to injury. To date, disease progression is typically assessed using invasive techniques such as muscle biopsies, and while there are recent reports of the use of magnetic resonance, ultrasound and optical imaging technologies to address the issue of disease progression and monitoring therapeutic intervention in dystrophic mice, our study aims to validate …

Colonoscopy has contributed to a marked decline in the number of colorectal cancer related deaths. However, recent data suggest that there is a significant (4-12%) miss-rate for the detection of even large polyps and cancers. To address this, we have been investigating an ‘automated feedback system’ which informs the endoscopist of possible sub-optimal inspection during colonoscopy. A fundamental step of this system is to distinguish non-informative frames from informative ones. Existing methods for this cannot classify water/bubble frames as non-informative even though they do not carry any useful visual information of the colon mucosa. In this paper, we propose a …

We propose a new fast spatio-temporal technique that detects an operation scene---a video segment corresponding to a single purpose diagnosis action or a single purpose therapeutic action. The technique utilizes (1) color contrast of the cable region and the background, (2) the new area-based coordinate system to compute spatial features, and (3) the history of locations of detected cables of the instrument in a video to discard false regions. The proposed technique and software are useful for (1) automatic documentation of diagnostic or therapeutic operations at the end of the procedure, (2) a second review for causes of complications due …

Recombinant adeno-associated viral (rAAV) vectors have been widely used in pulmonary gene therapy research. In this study, we evaluated the transduction and expression efficiencies of several AAV serotypes and AAV2 capsid mutants with specific pulmonary targeting ligands in the mouse lung. The noninvasive intranasal delivery was compared with the traditional intratracheal lung delivery. The rAAV8 was the most efficient serotype at expressing alpha-1-antitrypsin (AAT) in the lung among all the tested serotypes and mutants. A dose of 1 x 1010 vg of rAAV8-CB-AAT transduced a high percentage of cells in the lung when delivered intratrachealy. The serum and the broncho-alveolar …

Quality management and continuous improvement are paramount for businesses to survive and thrive in today’s competitive landscape (Goetsch & Davis, 2003; Abdullah et al., 2009). One effective approach to operationalize quality processes and continuous improvement goals is a formalized quality management system (Khanna et al., 2010; Mosher et al., 2013). Quality management systems are embodiments of the organization’s policies, procedures, plans, resources, processes and delegation of responsibility and authority designed to achieve customer satisfaction within the boundaries of organizational objectives (Goetsch & Davis, 2003). While these systems are being used extensively across many industries, the ideas are relatively new to …

Quality management practices have been identified by previous literature as a factor that could potentially reduce the level of safety incidents and hazards in agricultural work environments. The present study used multivariate analysis to examine the effect of independent variables such as quality and safety awareness, work experience, safety and quality management experience, and the perceived importance of safety and quality on the role of quality management practices as a mitigating factor for safety hazards and incidents in agriculture. Variables were measured on a five-point scale using a survey questionnaire. Data were collected from approximately 900 undergraduates enrolled in the …

Agriculture is a high-hazard industry that employs a large number of young workers below the age of 25. Recent studies have documented a strong positive correlation between quality management in agriculture and occupational safety as perceived by agricultural workers. Younger workers have been found to be at higher risk for occupational injuries and fatalities in agriculture. Furthermore, college students in agriculture have minimal exposure to safety and quality management principles in their coursework and thus may not be aware that the two concepts are associated. Little research has studied how young workers perceive the relationship between safety and quality and …
