Low-Cost Portable Light Therapy for Alzheimer's Patients

This paper provides an overview of the information and research conducted that ushered the creation and innovation of a low-cost portable light therapy device to help treat Alzheimer’s patients. Alzheimer’s has afflicted over five million people in the U.S., currently has fewer effective treatment options than other diseases, such as cancer. Of all known research, light flickering at 40 Hz at the eyes of patients has proven to be the most effective treatment for the disease. This information was used in creating the Light Therapy boxes.Cockrell School of Engineerin

Abelian Projective Planes of Square Order

We prove that, under certain conditions, multipliers of an abelian projective plane of square order have odd order modulo v*, where v* is the exponent of the underlying Singer group. As a consequence, we are able to establish the non-existence of an infinite number of abelian projective planes of square order

Key Influences of Patient Satisfaction Measurement as a Quality Indicator in Inpatient Facilities

Patient Satisfaction remains a focal point in overall healthcare experience. Satisfaction of patients has become a priority for hospital administrators because of the ties to improve organization performance, increase reimbursement schedules, prevent claims, and gain return to provider reputation. This study examines the key influences of patient satisfaction and how it is measured in an inpatient facility. A literature search was done through PubMed and Google Scholar to determine specific areas needing improvement. Out of 30 articles that met all search criteria (published in the year 2000 or later, survey administered in United States, published in English, administered in an inpatient facility, abstract of study pertained to one or more research questions, satisfaction scores analyzed through external agency, scores gathered from patients age 19 and older), the most frequently mentioned areas of dissatisfaction include: food, wait time, follow up/discharge, facility, medical personnel interaction, and activities/program. Further breakdown of specific points of dissatisfaction for each factor was determined by frequently mentioned specifics. The systematic review confirmed the concept that access, time, and medical personnel interaction are greatly valued by patients. Limitations of the study include the fact that response bias may exist for individuals answering surveys, interview bias may exist through wording of questionnaires, and the results are propriety in nature due to score analysis through third parties. Recommendations for assessment involve longer follow up period with the same patients and capturing a good sampling plan including both positive and negative experiences

On Wilbrink's Theorem

AbstractAn easy extension of Wilbrink's Theorem on planar difference sets for higher values of λ is given. It follows that the Bruck-Ryser-Hall conjecture on the super-fluousness of the “p > λ” condition (or its variations thereof) in the multiplier theorems implies Hall's conjecture on the existence of only a finite number of (ν, κ, λ) abelian difference sets, for the case λ odd and κ − λ ≡ 2 (mod 4). More strongly, under these conditions we can show that the corresponding designs are Hadamard, i.e., k = 2λ + 1 and ν = 2k + 1

Evaluation of Volumetric Change of Periapical Lesions After Apicoectomy as a Measure of Postsurgical Healing Utilizing Cone Beam Computed Tomography

The aim of this study was to evaluate whether volumetric changes in persistent periapical lesions can be detected in follow-ups six months to five years after apicoectomy using cone-beam computed tomography. Patients with a previous treatment history of apicoectomy and for whom a pre-surgical CBCT scan was taken between November 2010 and December 2015 were invited to participate in the study. A post-surgical CBCT image of the treated tooth was obtained at the recall visit. Volumetric and linear measurements of periapical lesions on initial and postoperative CBCT images were performed using DiThreshGUI software and two calibrated examiners—a board-certified endodontist and a board-certified oral radiologist. Repeated-measures ANOVA were used to estimate the magnitude of reduction and to test for differences (at alpha=0.05). A total of 20 patients with 27 surgically treated teeth were recalled at an average interval of 37 months. Reduction in the size of lesions was observed in 24 teeth (88%); overall, the volumes significantly decreased as detected by software-assisted measurement of volume (P = .0002) and by calculation from linear measurements (P \u3c .0001). Volumetric analysis detected a reduction of 86% in lesions while the linear-derived volume measurements yielded an average reduction of 96%. These two methods of lesion assessment were strongly correlated with one another in pre-surgical scans (r\u3e0.88) when apical lesions are measurable

Psychology in Sangam Songs

The hymns included in the Sangam literature date back two thousand years. Sangam literature, a new psychology which has emerged recently, is an early literature available in Tamil. The sum including the sum of that number is called the number. Patu means tens and Suma means eights These eight books were called Sangailyakyam. “If you ask for another name for associational literature, feel free to mention it as 'psychological literature'. There are one hundred internal songs and one hundred and seventy-five external songs. Palandamizhar literature was divided into two sections namely Akam and Puram. Songs that describe the life of a similar male and female son and daughter are called Agam Areas that tell about war, gift, victory etc. are called Puram. Inward life belongs to domestic pleasure and outward life to national pride. The psychological knowledge possessed by the Sangam saints who sang of the inner love life and the outer heroic life was remarkable

Creativity in the works of Kannadasan and Pattukkottaiyar

'Personality' can be defined as the success of the psychological impulse that expresses its full potential in the subjective and objective aspects of one or more, such as subconsciousness, mood, social expression, and the manner in which they deal with individual movement in their modes of action. The symbol of creativity depends on the nature of the work, the nature of the creator, and the consumer's reception of the work. Generally, this work applies not only to literary works but also to all kinds of works. The scope of this creativity expands around the central theme of creativity

Self-stabilizing wormhole routing in hypercubes

Wormhole routing is an efficient technique used to communicate message packets between processors when they are not completely connected. To the best of our knowledge, this is the first attempt at designing a self-stabilizing wormhole routing algorithm for hypercubes. Our first algorithm handles all types of faults except for node/link failures. This algorithm achieves optimality in terms of routing path length by following only the preferred dimensions. In an n-dimensional hypercube, those dimensions in which source and destination address bits differ are called preferred dimensions. Our second algorithm handles topological changes. We propose an efficient scheme of rerouting flits in case of node/link failures. Similar to the first algorithm, this algorithm also tries to follow preferred dimensions if they are nonfaulty at the time of transmitting the flits. However, due to topological faults it is necessary to take non-preferred dimensions resulting in suboptimality of path selection. Formal proof of correctness for both solutions is given.
