Electro-Pneumatic Wiring Software for Distance-Learning Students in Automation Control Laboratories
When teaching electro-pneumatic circuits in the automation control class for a distance-learning program, one of the main issues is how to provide hands-on experience for students. In most cases, they can only use simulation design software and watch videos solving laboratory problems without access to the actual equipment. In this paper, the authors developed an electrical wiring software and assembly platform which can help students enhance their hands-on experience when taking the course online. Results show that the performance between on-campus students and distance-learning (DL) students are very similar.Cockrell School of Engineerin
Signing Exact English; A Simultaneously Spoken and Signed Communication Option in Deaf Education
Current reviews of the literature continue to evidence that even with current assistive listening technology, many children who are deaf or hard-of-hearing (D/HH) persist in demonstrating English language and literacy gaps compared to hearing peers (e.g., C. Mayer 2016; C. Mayer, & Trezek, 2018). For example, Geers, Tobey, Moog, and Brenner (2008) reported that “only about half” (p. 262) of children using cochlear implants (CIs) (and no sign to support their speech production) achieved age-appropriate abilities by third grade. Given the continually-reported variability of results (e.g., Harris, 2016; C. Mayer, & Trezek, 2018), an alternative is warranted. Signing Exact English (S.E.E.), a system designed and demonstrated to encode grammatically-accurate English, is discussed as an option to support the development of speech, listening, English language and literacy when Listening and Spoken Language (LSL) or American Sign Language (ASL) are not deemed appropriate by teams discussing Individual Family Service Plans (IFSP) or Individualized Educational Program (IEP). In this article, S.E.E. as it is used in the United States, is contrasted with the many terms that have been used to describe the practice of simultaneously speaking and signing (e.g., total communication, simultaneous communication, sign supported speech, etc.). Research-based responses to common remarks about S.E.E. are also provided
21st Century Lunar Exploration: Advanced Radiation Exposure Assessment
On January 14, 2004 President George W Bush outlined a new vision for NASA that has humans venturing back to the moon by 2020. With this ambitious goal, new tools and models have been developed to help define and predict the amount of space radiation astronauts will be exposed to during transit and habitation on the moon. A representative scenario is used that includes a trajectory from LEO to a Lunar Base, and simplified CAD models for the transit and habitat structures. For this study galactic cosmic rays, solar proton events, and trapped electron and proton environments are simulated using new dynamic environment models to generate energetic electron, and light and heavy ion fluences. Detailed calculations are presented to assess the human exposure for transit segments and surface stays
Analysis of Successful Initiations of Three Children With Hearing Loss Mainstreamed in Kindergarten Classrooms
This is the published version, also available here: http://dx.doi.org/10.1044/0161-1461.2601.45.The communicative interactions of three
mainstreamed children who are deaf or hard of hearing
(deaf/HOH) were investigated. These children were
matched with a classmate who had normal hearing (NH)
according to chronological age, sex, race, and socioeconomic
status (SES). All subjects were white females
approximately 5 years of age. The subjects were videotaped
while involved in normal classroom activities. The
videotaped interactions were coded for: (a) activity, (b) play
level, (c) partner, (d) interactive status, and (e) mode of
communication
Addressing New Skills Needed for the Automotive Industry through a Motorsports Educational Pathway
The automotive industry has higher-skilled positions available that need engineers and engineering technologists qualified and capable to work in a high-paced, advanced manufacturing sector. Various educational programs across the country offer programs related to the motorsports area at the Associate of Science level. There are also various articu-lation agreements that enable students to continue their education to the baccalaureate level. These programs try to fill in the gap related to the skills shortage in systems and new design methods and processes. The main strength of such educational pathways is that students, who are trained to work as technicians with an associate\u27s degree in automotive and motorsports areas and then continue onto complete their four-year undergraduate degree, have specific skills highly sought by the automotive industry. In this paper, the authors present an example of such an educational pathway, with an emphasis on motorsports
Integration of Mechatronics Design Approach into Teaching of Modeling Practices
Engineering design has transformed significantly due to advances in embedded system design and computer technologies. Almost every mechanical design today has some electrical and electronic components. Many products manufactured today contain both electrical and mechanical components and systems. Mechatronics is a design process that is multi-disciplinary in nature and integrates principles of many engineering disciplines including, but not limited to, mechanical engineering and mechanical engineering technology, electrical engineering and electrical engineering technology, and controls engineering. Mechatronic systems can be found in many different places today. These range from computer hard drives and robotic assembly systems, to washing machines, coffee makers, printers, and medical devices, as well as to various advanced manufacturing machines and devices that are numerically controlled, such as additive manufacturing machines, rapid prototyping machines and multi-axis CNC machines. The main purpose for integrating a mechatronics themed activity into a computer-modeling course is to engage students in project-based learning through hands-on activities related to modeling a mechatronic device. Students learn the basics of electromechanical systems, the integration of machine elements (gear reducer) and the basics of actuators (electrical motor), all of which are fundamental to understanding mechatronic systems through activities related to the mechatronic design principles. Hence, engineering design for mechanical engineers and mechanical engineering technologists have to involve embedded multi-disciplinary knowledge with the understanding of both mechanical and electrical systems. This paper will focus on presenting the use of modeling as a vehicle to teaching more complex engineering concepts, such as gears, linkage analysis, animation and the solid modelling course content
80. Disparities in Perceived Vulnerability to COVID-19 Consequences Among U.S. Adolescents and Young Adults: Findings from a Nationally Representative Survey
Global research has documented the adverse impact of COVID-19 on the health and well-being of adolescents and young adults (AYA). Pandemic conditions can increase AYA vulnerability to COVID-19-related health (e.g. getting sick or missing medical appointments), social (e.g. not having enough to eat) and economic (e.g. job loss) consequences. Structural inequalities may further exacerbate exposure to these outcomes. We used nationally representative data to examine AYA perceived vulnerability to health/social outcomes early in the COVID-19 pandemic
A Dynamic/Anisotropic Low Earth Orbit (LEO) Ionizing Radiation Model
The International Space Station (ISS) provides the proving ground for future long duration human activities in space. Ionizing radiation measurements in ISS form the ideal tool for the experimental validation of ionizing radiation environmental models, nuclear transport code algorithms, and nuclear reaction cross sections. Indeed, prior measurements on the Space Transportation System (STS; Shuttle) have provided vital information impacting both the environmental models and the nuclear transport code development by requiring dynamic models of the Low Earth Orbit (LEO) environment. Previous studies using Computer Aided Design (CAD) models of the evolving ISS configurations with Thermo Luminescent Detector (TLD) area monitors, demonstrated that computational dosimetry requires environmental models with accurate non-isotropic as well as dynamic behavior, detailed information on rack loading, and an accurate 6 degree of freedom (DOF) description of ISS trajectory and orientation
Calculation of Radiation Protection Quantities and Analysis of Astronaut Orientation Dependence
Health risk to astronauts due to exposure to ionizing radiation is a primary concern for exploration missions and may become the limiting factor for long duration missions. Methodologies for evaluating this risk in terms of radiation protection quantities such as dose, dose equivalent, gray equivalent, and effective dose are described. Environment models (galactic cosmic ray and solar particle event), vehicle/habitat geometry models, human geometry models, and transport codes are discussed and sample calculations for possible lunar and Mars missions are used as demonstrations. The dependence of astronaut health risk, in terms of dosimetric quantities, on astronaut orientation within a habitat is also examined. Previous work using a space station type module exposed to a proton spectrum modeling the October 1989 solar particle event showed that reorienting the astronaut within the module could change the calculated dose equivalent by a factor of two or more. Here the dose equivalent to various body tissues and the whole body effective dose due to both galactic cosmic rays and a solar particle event are calculated for a male astronaut in two different orientations, vertical and horizontal, in a representative lunar habitat. These calculations also show that the dose equivalent at some body locations resulting from a solar particle event can vary by a factor of two or more, but that the dose equivalent due to galactic cosmic rays has a much smaller (<15%) dependence on astronaut orientation
The relationship between a microfinance-based healthcare delivery platform, health insurance coverage, health screenings, and disease management in rural Western Kenya
BACKGROUND: Structural barriers often prevent rural Kenyans from receiving healthcare and diagnostic testing. The Bridging Income Generation through grouP Integrated Care (BIGPIC) Family intervention facilitates microfinance groups, provides health screenings and treatment, and delivers education about health insurance coverage to address some of these barriers. This study evaluated the association between participation in BIGPIC microfinance groups and health screening/disease management outcomes.
METHODS: From November 2018 to March 2019, we interviewed a sample of 300 members of two rural communities in Western Kenya, 100 of whom were BIGPIC microfinance members. We queried participants about their experiences with health screening and disease management for HIV, diabetes, hypertension, tuberculosis, and cervical cancer. We used log-binomial regression models to estimate the association between microfinance membership and each health outcome, adjusting for key covariates.
RESULTS: Microfinance members were more likely to be screened for most of the health conditions we queried, including those provided by BIGPIC [e.g. diabetes: aPR (95% CI): 3.46 (2.60, 4.60)] and those not provided [e.g. cervical cancer: aPR (95% CI): 2.43 (1.21, 4.86)]. Microfinance membership was not significantly associated with health insurance uptake and disease management outcomes.
CONCLUSIONS: In rural Kenya, a microfinance program integrated with healthcare delivery may be effective at increasing health screening. Interventions designed to thoughtfully and sustainably address structural barriers to healthcare will be critical to improving the health of those living in low-resource settings
