Improving Global Healthcare by Focusing in Quality
No full text© ASEE 2015Global health care can be improved through the use of sound quality management strategies. Health care quality is defined as the ability of the facilities to provide safe medical care to patients and achieve the anticipated health outcomes. The main quality aspects in healthcare include: patient safety, effectiveness, patient centered services, the ability to provide health care services to the patient on time, efficiency and equity. Previous research and cohort studies document the use of quality as a vital tool in global health. These researches raise a number of issues that can be used to improve quality. In this paper, a systematic literature review was conducted. Data was collected from already published materials on health care quality. The data was analyzed through content analysis to determine the major perspectives. The results indicate that the main quality aspects that improve global health are the use of information technology and e health solutions, use of strategic human resource management, training health care workers, reducing disparities when providing healthcare services, developing good policies that improve healthcare quality, use of evidence based practice, improving the medical service efficiency and patient safety

If you are the author of this work and desire to provide it open access or wish access removed, please contact the Wahlstrom Library to discuss permission.Objective – The purpose of this study was to evaluate the benefits of dietary energy restriction in the aging process. This study looks at the research showing the physiology and theories of aging, hormesis, intermittent fasting, calorie restriction, and specific measures in cellular health and physiological aging. The information was compiled to gain an understanding of the impact of dietary energy restriction on the aging process and to evaluate if dietary energy restriction promotes healthy aging and delays frailty. Basic Procedures – The databases used for searching included PubMed, Science Direct, and Eureka /One Search through University of Bridgeport. Research focused on papers showing the aging process, hormesis, intermittent fasting, calorie restriction, and specific mechanisms of monitoring blood sugar, cell turnover, and weight management in the aging process. The majority of papers chosen were published within the last 15 years, with one study on intermittent fasting from 1945. Main Findings – Calorie Restriction and Intermittent Fasting regimens correlate with increased longevity and with decreased risk factors for cardiovascular disease, diabetes mellitus, and cancer. Fasting has also been linked to postponing Alzheimer's, Dementia, and loss of cognitive function. Some research suggests fasting promotes new neuronal growth. There are several areas of thought with different ways to practice calorie restriction and intermittent fasting. Biomarkers such as IGF-1, total cholesterol, LDL, HDL, TG, fasting blood sugar, along with BMI, weight, height, and waist measurements were used to assess disease risk factors, assess overall health, and compare studies. Other biomarkers or pathways were also assessed in the process of evaluating the effectiveness of fasting and calorie restriction. Principal Conclusions - Calorie Restriction and Intermittent Fasting regimens show reduction in blood biomarkers along with changes in body composition that support healthier aging. The different forms of calorie restriction and intermittent fasting together have strong evidence to support a lifestyle change that incorporates food restriction one way or another. Both groups showed decreased risk factors for cardiovascular disease, diabetes, and cancer. Groups that should not attempt CR or IF include pregnancy, eating disorders, and people with very low body weight and fat content
Detection of Metallic and Non Metallic Objects on a Conveyor Belt Using PLC Logics, HMI Screen, VFD
No full text© ASEE 2015This project was created to control and monitor movable parts on the conveyor belt by a Human Machine Interface (HMI). In our application, we separate metallic and non-metallic objects. This application could be used in pharmaceutical, electronic industries or any industry which deals with metals/plastic. An eye sensor and a proximity sensor have been used to detect the non- metallic and metallic objects respectively. According to that the counter counts non-metallic and metallic objects and display the value on the HMI, whenever a metallic object is detected Air cylinder pushes it out of the conveyor belt and allows non-metallic objects to reach till the end of conveyor. PLC with series FX3U-16MR/ES manufactured by Mitsubishi is used in this project. This logic can handle a series of metallic and non-metallic objects. To control the speed of the conveyor VFD (Variable Frequency Drive) is programmed and used.E-Designer-7 software is used to design the screen. GX Developer software has been used to create PLC logic
Robust Text Steganography Algorithms for Secure Data Communications
No full textIn the era of information technology, a large amount of digital information is distributed over the Internet in the form of videos, images, text, and audio. The main purpose of widespread distribution enables users to share knowledge between one another. As a result, data transmission and information sharing are effected due to malicious activities. Different techniques exist to protect user authentication, data privacy, and copyrights. Two main techniques that improve security and data protection are Cryptography and Steganography. Cryptographic algorithms convert the secret message from plain text into cipher text. Then the message is sent over the communication channel. Steganography hides a secret message inside the carrier media. This proposal will investigate different Steganography algorithms and present novel algorithms employing text file as a carrier file. The proposed model hides secret data in the text file by applying various properties into file font format by inserting special symbols in the text file. In addition, the suggested model can be applied in both Unicode and ASCII code languages, regardless of the text file format. The proposed system achieves a high degree of the main Steganography attributes like hidden ratio, robustness, and transparency. In addition, this proposal provides guidance for other researchers in text Steganography algorithms
Implications of Unchecked Exponential Growth
No full textTreatments of the exponential function in Calculus textbooks are often cursory in that they treat unchecked (Malthusian) growth processes without examination of their consequences. Through the use of problems posed to students, we illustrate the implications of such processes when applied to growth of populations and to growth in the rates of consumption of nonrenewable resources

No full textThis thesis is being archived as a Digitized Shelf Copy for campus access to current students and staff only. We currently cannot provide this open access without the author's permission. If you are the author of this work and desire to provide it open access or wish access removed, please contact the Wahlstrom Library to discuss permission.Recently, the clinical uses of Dipsaci radix in the treatments of arthritis like symptoms have been noticed a lot amongst natural and integrative medicine practitioners in US. Dipsacus spp has been mainly used as teasers for combing wools in western world 5, 6, 36, wherein the eastern world, the effects of the herb have been appreciated for hundreds of years as a potent muscle and joint healer and effective blood circulator 3, 18, 39. The purpose of this research is to investigate whether the radix of Dipsacus spp (commonly known as Teasel root) has beneficial medicinal properties, and to identify what properties have been studied and what have not. As many valuable botanicals have been known to be very effective clinically, but also been lacking in actual scientific studies to prove the efficacy, the clarification in the current status of the studies may be helpful in implementing the treatment protocols with more controlled approaches. Knowing what is anecdotal, clinically proven or scientifically proven, may always be a important step for any practitioners. There are many different species of Dipsacus; however, for the purpose of the research, only the common species used for Dipsaci radix will be discussed here to stay in focus for the proper clinical use
Multi-Class SVM Based on Sleep Stage Identification Using EEG Signal
No full textCurrently, sleep disorders are considered as one of the major human life issues. Human sleep is a regular state of rest for the body in which the eyes are not only usually closed, but also have several nervous centers being inactive; hence, rendering the person either partially or completely unconscious and making the brain a less complicated network. This paper introduces an efficient technique towards differentiating sleep stages to assist physicians in the diagnosis and treatment of related sleep disorders. The idea is based on easily implementable filters in any hardware device and feasible discriminating features of the Electroencephalogram (EEG) signal by employing the one-against-all method of the multiclass Support Vector machine (SVM) to recognize the sleep stages and identify if the acquired signal is corresponding to wake, stage1, stage2, stage3 or stage4.The experimental results on several subjects achieve 92% of classification accuracy of the proposed work. A comparison of our proposed technique with some recent available work in the literature also presents the high classification accuracy performance
MEMS Piezoelectric Vibration Energy Harvester with Three-DOF Responses
No full text© ASEE 2015Vibration energy harvester can convert mechanical vibration energy into electrical energy and store it in battery for later use. It can create clean renewable energy from vibration movements such as walking, jumping, running, etc. This can convert energy previously wasted into useful energy for charging portable electronic devices, wireless sensors. If such devices are widely used, it can generate a large amount of green energy and help protect the environment. Most MEMS energy harvesters are designed to harvest energy from one direction only. In this research, a MEMS piezoelectric vibration energy harvester with three-DOF (degree-of-freedom) responses is proposed. The device consists of two silicon masses suspended by two sets of T-shape beams from both sides. The four sets of folded beams in both sides allow the mass to vibrate along the X direction. The two sets of straight beams allow the mass to vibrate along both Y and Z directions. The Piezoelectric material is pre-deposited along the surfaces of the beams. It can convert the vibration energy of beams into electric voltage, which is passed through a rectifying circuit to charge a battery. The device can harvest vibration energy along all three axes, resulting more effective energy harvesting outcome. It is designed and simulated in COMSOL. The proposed MEMS energy harvester can be attached to shoes, tires or other vibrating surfaces to harvest energy from the movement of walking, running, driving for clean energy generation.Electrical Engineering Department, School of Engineering, University of Bridgeport
