A functional video-based anthropometric measuring system

A high-speed anthropometric three dimensional measurement system using the Selcom Selspot motion tracking instrument for visual data acquisition is discussed. A three-dimensional scanning system was created which collects video, audio, and performance data on a single standard video cassette recorder. Recording rates of 1 megabit per second for periods of up to two hours are possible with the system design. A high-speed off-the-shelf motion analysis system for collecting optical information as used. The video recording adapter (VRA) is interfaced to the Selspot data acquisition system

Equipment Development for Automatic Anthropometric Measurements

An automated procedure for measuring and recording the anthropometric active angles is presented. The small portable system consists of a microprocessor controlled video data acquisition system which measures single plane active angles using television video techniques and provides the measured data on sponsored-specified preformatted data sheets. This system, using only a single video camera, observes the end limits of the movement of a pair of separated lamps and calculates the vector angle between the extreme positions

Modification and Assessment of the Bedside Pediatric Early Warning Score in the Pediatric Allogeneic Hematopoietic Cell Transplant Population

OBJECTIVES: To determine the validity of the Bedside Pediatric Early Warning Score system in the hematopoietic cell transplant population, and to determine if the addition of weight gain further strengthens the association with need for PICU admission. DESIGN: Retrospective cohort study of pediatric allogeneic hematopoietic cell transplant patients from 2009 to 2016. Daily Pediatric Early Warning Score and weights were collected during hospitalization. Logistic regression was used to identify associations between maximum Pediatric Early Warning Score or Pediatric Early Warning Score plus weight gain and the need for PICU intervention. The primary outcome was need for PICU intervention; secondary outcomes included mortality and intubation. SETTING: A large quaternary free-standing children's hospital. PATIENTS: One-hundred two pediatric allogeneic hematopoietic cell transplant recipients. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of the 102 hematopoietic cell transplant patients included in the study, 29 were admitted to the PICU. The median peak Pediatric Early Warning Score was 11 (interquartile range, 8-13) in the PICU admission cohort, compared with 4 (interquartile range, 3-5) in the cohort without a PICU admission (p < 0.0001). Pediatric Early Warning Score greater than or equal to 8 had a sensitivity of 76% and a specificity of 90%. The area under the receiver operating characteristics curve was 0.83. There was a high negative predictive value at this Pediatric Early Warning Score of 90%. When Pediatric Early Warning Score greater than or equal to 8 and weight gain greater than or equal to 7% were compared together, the area under the receiver operating characteristic curve increased to 0.88. CONCLUSIONS: In this study, a Pediatric Early Warning Score greater than or equal to 8 was associated with PICU admission, having a moderately high sensitivity and high specificity. This study adds to literature supporting Pediatric Early Warning Score monitoring for hematopoietic cell transplant patients. Combining weight gain with Pediatric Early Warning Score improved the discriminative ability of the model to predict the need for critical care, suggesting that incorporation of weight gain into Pediatric Early Warning Score may be beneficial for monitoring of hematopoietic cell transplant patients

The Domain Interface of the Human Glutamate Transporter EAAT1 Mediates Chloride Permeation

AbstractThe concentration of glutamate within the glutamatergic synapse is tightly regulated by the excitatory amino-acid transporters (EAATs). In addition to their primary role of clearing extracellular glutamate, the EAATs also possess a thermodynamically uncoupled Cl− conductance. Several crystal structures of an archaeal EAAT homolog, GltPh, at different stages of the transport cycle have been solved. In a recent structure, an aqueous cavity located at the interface of the transport and trimerization domains has been identified. This cavity is lined by polar residues, several of which have been implicated in Cl− permeation. We hypothesize that this cavity opens during the transport cycle to form the Cl− channel. Residues lining this cavity in EAAT1, including Ser-366, Leu-369, Phe-373, Arg-388, Pro-392, and Thr-396, were mutated to small hydrophobic residues. Wild-type and mutant transporters were expressed in Xenopus laevis oocytes and two-electrode voltage-clamp electrophysiology, and radiolabeled substrate uptake was used to investigate function. Significant alterations in substrate-activated Cl− conductance were observed for several mutant transporters. These alterations support the hypothesis that this aqueous cavity at the interface of the transport and trimerization domains is a partially formed Cl− channel, which opens to form a pore through which Cl− ions pass. This study enhances our understanding as to how glutamate transporters function as both amino-acid transporters and Cl− channels

Designing an International Experience Program for 4-H Members in Louisiana

In recent years, the U.S. Cooperative Extension Program (CEP) has worked to develop international exchange programs (IEPs) for 4-H members in some states. However, no such program currently exists in Louisiana. As such, the purpose of this descriptive study was to identify the IEP participation preferences held by 4H members in Louisiana to inform future IEP development and implementation. 4-H members in this study preferred to participate in a short-term IEP during the summer of the 11th grade. Thus, it is recommended that IEP recruitment be geared toward students in the 9th and 10th grades. 4-H members preferred to participate in an IEP located in Europe or Australia/New Zealand. Future research should examine which characteristics of these locations appeal to 4-H members to broaden the appeal of IEPs in other locations. Career related courses and hands-on experience were perceived by 4-H members as important activities to include in the IEP design, whereas staying with a host family was not. Future research should assess whether this finding is specific to members in this study or representative of a national trend that warrants reexamination of the overall design of 4-H IEPs employed by the U.S. CEP

User quality of experience of mulsemedia applications

User Quality of Experience (QoE) is of fundamental importance in multimedia applications and has been extensively studied for decades. However, user QoE in the context of the emerging multiple-sensorial media (mulsemedia) services, which involve different media components than the traditional multimedia applications, have not been comprehensively studied. This article presents the results of subjective tests which have investigated user perception of mulsemedia content. In particular, the impact of intensity of certain mulsemedia components including haptic and airflow on user-perceived experience are studied. Results demonstrate that by making use of mulsemedia the overall user enjoyment levels increased by up to 77%
