Development and Usability Testing of a Web-Based and Therapist-Assisted Coping Skills Program for Managing Psychosocial Problems in Individuals With Hand and Upper Limb Injuries: Mixed Methods Study

Background Ineffective coping has been linked to prolonged pain, distress, anxiety, and depression after a hand and upper limb injury. Evidence shows that interventions based on cognitive behavioral therapy (CBT) may be effective in improving treatment outcomes, but traditional psychological interventions are resource intensive and unrealistic in busy hand therapy practices. Developing web-based, evidence-based psychological interventions specifically for hand therapy may be feasible in clinical practice and at home with reduced training and travel costs. Hand Therapy Online Coping Skills (HOCOS) is a program developed to supplement traditional hand therapy with therapist-assisted coping skills training based on principles from CBT and the Technology Acceptance Model. Objective This study aimed to describe the development and assess the usability of HOCOS to support hand therapists in the management of psychosocial problems. Methods The ADDIE model (Analysis, Design, Development, Implementation, and Evaluation) of system design was applied to create HOCOS. The usability testing of HOCOS involved a 2-stage process. In the first step, heuristic testing with information and communications technology (ICT) experts was completed using two sets of heuristics: Monkman heuristics and the Health Literacy Online (HLO) checklist. The second step involved user testing with hand therapists performing a series of online and face-to-face activities, completing 12 tasks on the website using the think-aloud protocol, completing the system usability scale (SUS) questionnaire, and a semistructured feedback interview in 2 iterative cycles. Descriptive statistics and content analyses were used to organize the data. Results In total, 4 ICT experts and 12 therapists completed usability testing. The heuristic evaluation revealed 15 of 35 violations on the HLO checklist and 5 of 11 violations on the Monkman heuristics. Initially, hand therapists found 5 tasks to be difficult but were able to complete all 12 tasks after the second cycle of testing. The cognitive interview findings were organized into 6 themes: task performance, navigation, design esthetics, content, functionality and features, and desire for future use. Usability issues identified were addressed in two iterative cycles. There was good agreement on all items of the SUS. Overall, therapists found that HOCOS was a detailed and helpful learning resource for therapists and patients. Conclusions We describe the development and usability testing of HOCOS; a new web-based psychosocial intervention for individuals with a hand and upper limb injuries. HOCOS targets psychosocial problems linked to prolonged pain and disability by increasing access to therapist-guided coping skills training. We actively involved target users in the development and usability evaluation of the website. The final website was modified to meet the needs and preferences of the participants.
An approach for generating and detecting the signals with the given orbital angular momentum for wireless communication systems

The paper is devoted to the development of methods for increasing the efficiency of wireless communication channels via the usage of multiplexing by the orbital angular momentum (OAM). This wave property allows us to form an additional basis of orthogonal functions for the simultaneous independent transmission of several signals. In particular, we propose the uniform circular antenna array (UCA) operating in the 77 – 78.5 GHz frequency range designed to generate radio beams with various orders of the OAM without changing its configuration. The important points in the UCA’s design process were ensuring the minimum divergence of the beam during the propagation and obtaining the maximum gain. Regarding the OAM radio beams receiver, we propose a solution for detecting an OAM signal in case of misalignment between transmitting and receiving antennas. An antenna array consisting of two perpendicular dipoles is employed as a receiving device, providing the OAM signal reception from any direction. An important point of signal detection is the preservation of the information about the phase of the received signal. Finally, we demonstrate the simulation results of OAM signal transmission and reception.
Applications of high-speed camera systems

Meteor detection and analysis is an essential topic in the field of astronomy. In this paper, a high-sensitivity and high-time-resolution imaging device for the detection of faint meteoric events is presented. The instrument is based on a fast CCD camera and an image intensifier. Two such instruments form a double-station observation network. The MAIA (Meteor Automatic Imager and Analyzer) system has been in continuous operation since 2013 and has successfully captured hundreds of meteors belonging to different meteor showers, as well as sporadic meteors. A data processing pipeline for the efficient processing and evaluation of the massive amount of video sequences is also introduced in this paper.
Food functionalities and bioactivities of protein isolates recovered from skipjack tuna roe by isoelectric solubilization and precipitation

Abstract Four roe protein isolates (RPIs) from skipjack tuna were prepared using isoelectric solubilization (pH 11 and 12) and precipitation (pH 4.5 and 5.5) (ISP) at different pH points to evaluate their physicochemical and functional properties and in vitro bioactivities. Moisture (<6.3%) and protein (71%–77%) content were maintained. Sulfur, sodium, phosphorus, and potassium were the major elements, and glutamic acid and leucine were the prevalent amino acids (12.2–12.8 and 9.6–9.8 g/100 g protein, respectively) in RPIs. RPI‐1 showed the highest buffering capacity at pH 7–12. RPIs and casein showed similar water‐holding capacities. At pH 12, RPI‐1(pH 11/4.5) showed the highest solubility, followed by RPI‐3(pH 12/4.5), RPI‐2(pH 11/5.5), and RPI‐4(pH 12/5.5) (p < .05). Oil‐in‐water emulsifying activity indices of RPI‐1 and RPI‐3 significantly differed. At pH 2 and 7–12, pH‐shift treatment improved the food functionality of RPIs, which was superior to positive controls (casein and hemoglobin). RPI‐1 showed ABTS+ radical scavenging (102.7 μg/ml) and angiotensin‐converting enzyme inhibitory activities (44.0%).
Atmospheres in Urban Light

Inescapably spatial and located in experience, understanding atmospheres and their impact means close empirical attention to how they arise and are constituted, how they impress upon us, how they circulate and are shared, and what configures to make them feel differently for diverse people. In this article, we advance a dialogic autoethnographic methodology for attuning to, exploring and understanding atmospheres that accounts for them as they arise in the ongoing flow of experience of light. In this ethnographic approach, we research in atmospheres – that is, in the ongoing flow and change of shifting impressions and feelings constituted spatially by a multiplicity of elements. Taking a ‘light walk’ through inner city Melbourne as our example, we interrogate our experience of atmospheres in light, and also address how they might be purposefully constituted or designed.
Rescue strategies for Xylopia sericea A.St.-Hil. plants from natural regeneration

The objective of this study was to test different rescue strategies of Xylopia sericea plants from natural regeneration. Two experiments were conducted in a completely randomized design, in split-plots, with the first one consisting of four levels of shading (0 or full sun, 30, 50 and 70% of shading) and four substrates; and the second consisting of four levels of shading and three leaf reduction intensities (0, 50 and 100%). After 150 days from the rescue, the survival and increments in height and diameter were obtained. The general mean survival was 26.1% in the first experiment and 26.7% in the second one. In both experiments the plants in full sun resulted in 100% mortality, while the 70% shading showed to be more effective concerning the survival and in the growth resumption. It is recommended to use substrates whose mixture has at least 50% subsoil as one of its components. Overall, the results obtained by leaf reduction were not sufficient to justify and recommend this procedure, taking into account the increase of the process total costs.
The effect of ankle-foot orthoses constrained movements on power output during functional electrical stimulation cycling in paraplegics / Puteri Nur Farhana Hamdan

Previous research has investigated functional electrical stimulation (FES) cycle power output (PO) from the perspective of knee and hip joint biomechanics. However, ankle-foot biomechanics and, in particular, the effect of releasing the ankle joint on cycle pedal PO during FES cycling in individuals with spinal cord injury (SCI) has not been widely explored. Therefore, the purpose of this study is to determine whether releasing the ankle joint might influence the peak and average pedal PO during FES cycling in individuals with SCI. Seven individuals with motor complete SCI (C5-T11) participated in this study. All participants performed two sessions of FES cycling. For each session, the participants were required to cycle in fixed- and free-ankle setup, in randomized order. There were two stimulation modes of FES cycling for each session. In mode 1, the participants were required to perform FES cycling with the stimulation of the upper leg muscles [quadriceps (QUAD) and hamstrings (HAM)] (known as QH stimulation). In mode 2, the participants were required to perform FES cycling with the stimulation of both upper and lower leg muscles [QUAD, HAM, tibialis anterior (TA), and triceps surae (TS)] (known as QHT stimulation). The peak and average pedal PO of each condition were analyzed. Overall, there was no significant difference in the normalized peak and average pedal PO between fixed- and free-ankle FES cycling for both stimulation modes [F (3, 24) = 0.32, P = 0.81 and F (3, 24) = 1.19, P = 0.33, respectively]. However, the free-ankle FES cycling with QH stimulation contributed to the lowest normalized peak and average pedal POs compared to the other modes of FES cycling (0.66 ± 0.23 and 0.16 ± 0.07 W/W, respectively). The present study revealed that free-ankle FES cycling without the stimulation of shank muscles (TA and TS) caused loss of power during recovery phase of cycling. The power from the hip and knee was lost at the ankle joint, and thus produced low pedal PO. On the other hand, free-ankle FES cycling with QHT stimulation provided greater ankle ROM while preventing power loss from the hip and knee at the ankle joint. The TS muscles stimulation is very important in free-ankle FES cycling to maximize the pedal PO. This finding might serve as a reference for future rehabilitative cycling protocols where both ankle muscle stretching and strength training are the simultaneous aim.
Immission-Based Noise Reduction within Conceptual Aircraft Design

The noise on the ground not only depends on the aircraft design itself, but also on the observer location and the operating conditions of the aircraft along its flightpath. Therefore, it is inevitable to consider the individual flightpaths of each aircraft concept. This allows to fully assess the noise reduction potential for the community. In order to compute individual low-noise flightpaths for different aircraft concepts, the tool Flightpaths for Noise Analyses (FlipNA) is developed and integrated into an existing noise prediction process. The application of FlipNA focuses on three existing tube-and-wing aircraft. One aircraft is conventional, whereas two aircraft feature an engine position that offers significant fan noise shielding. To also consider different engine types during departure, two other aircraft of the Collaborative Research Center 880 are assessed. Results show that noise reduction is achieved for all three aircraft when individual low-noise flightpaths are used. Along the departure flightpaths, the noise on the ground of the two new aircraft is significantly lower compared to the conventional aircraft. The assessment of different engine types along departure flightpaths shows, that the operating conditions for minimum noise significantly depends on the engine performance and its specific noise characteristics. In summary, the necessity and benefit of considering individual flightpaths and the noise source ranking within the conceptual aircraft design phase is demonstrated. Only then can the full noise reduction potential of individual aircraft be exploited.
Analysis of the effects of removable dentures on the psychological status, quality of life, and masticatory function of the elderly

Older age is a major risk factor for diseases of the teeth and mouth and dementia. Diseases of the teeth and mouth can lead to tooth loss. The use of removable dentures can help the elderly to replace lost teeth; therefore, dentures are expected to improve the masticatory function, quality of life, and psychological status of the elderly. The aim of this study was to analyze the effects of removable denture usage on the improvement of the psychological status, quality of life, and masticatory function of elderly people. The data was obtained from 30 respondents. The patients answered questionnaires before they used the dentures, 2 weeks after they began using dentures, and 2 months after they started wearing dentures. Four different questionnaires were used: EuroQol Five Dimensions questionnaire (EQ-5D) and Geriatric Depression Scale (GDS), to measure psychological status; a mastication questionnaire to measure masticatory function; and a validated quality of life questionnaire. Based on the results of this study, it is clear that after 2 months of denture usage, removable dentures in the elderly can significantly improve their quality of life, masticatory function, and psychological status(p<0.05).
Energy-Efficient Torque Distribution Optimization for an Omnidirectional Mobile Robot with Powered Caster Wheels

A mobile robot with no less than two powered caster wheels (PCWs) has the ability to perform omnidirectional motions and belongs to a redundantly actuated system. Redundant actuation will bring the issue of non-uniqueness of actuating torque distribution, and inappropriate choices of torque distribution schemes will lead to unexpected large required actuating torques and extra energy consumption. This paper proposes a new torque distribution optimization approach based on a gradient projection method (GPM) for the omnidirectional mobile robot (OMR) with direct drive PCWs. It can significantly reduce the maximal required actuating torque and the energy consumption of the system. The modular kinematic and dynamic modeling method is presented first, which is suitable for an arbitrary number of employed PCWs, as well as their install positions in the chassis. The detailed energy consumption model of the OMR, including output energy consumption and electrical energy loss, is formulated through experimental testing. The effectiveness of the proposed algorithms is validated by simulation examples. Lastly, the computational efficiency of the method is verified
Digitalización y personas

espanolLas organizaciones empresariales en nuestros dias estan viviendo una transformacion profunda y, en cierto modo, sui generis provocada, principalmente, por la poderosa influencia de las nuevas tecnologias en sus variadas versiones.

EnglishBusiness organizations are experiencing a deep transformation and, in a way, “sui generis” caused, mainly, by the powerful influence of new technologies in their varied versions. This obliges them, among others, to modify organizational structures and people management policies with a double goal: firstly, to guarantee their competitiveness and, secondly, to ensure that the necessary environment which allows the provision and prosperity of the adequate talent is cultivated. With this basic purpose, throughout the following article the three main trends - identified by the authors - that influence the current configuration of organizations will be analyzed, that is: the proliferation of agile environments that allow to adapt quickly and dynamically to the continuous changes in the market, which bring new ways of directing, organizing and managing people not exempt from difficulties and peculiarities; the necessary adaptation of performance management systems according to the new business demands and the emergence of the younger generations in the labor market; and, finally, the emergence of advanced tools and techniques for massive data analysis that ask for additional reflections on their use and the risks that its potential abuse entails.
Modulation of Whistler Mode Waves by Ion‐Scale Waves Observed in the Distant Magnetotail

Wave activities in tailward flows have been explored in the distant magnetotail at ~54 RE, where the coupling between whistler mode waves and ion‐scale waves was observed. The whistler mode waves periodically appeared at each cycle of the ion‐scale waves, and the electron distribution functions associated with the whistler mode waves showed enhancement in the direction parallel to background magnetic field. Wave analyses show that the field‐aligned electron components act as the energy source of the whistler mode waves. The ion‐scale waves are generated by the interaction of the hot ion beam with background ions. A likely candidate of the ion‐scale wave is the kinetic Alfven wave, which can generate the enhanced field‐aligned electron populations by the parallel electric field.
Weeks‐Long and Years‐Long Slow Slip and Tectonic Tremor Episodes on the South Central Alaska Megathrust

We jointly investigate aseismic slip transients and tremor activity in south central Alaska. Near the eastern downdip edge of the Mw 9.2 1964 Prince Williams earthquake rupture, kinematic modeling of the Mw=7.6 2009–2013 slow slip event suggests cumulative transient slip of up to 55 cm. During this 5‐year transient event, tectonic tremors were co‐located with the inferred aseismic slip zone and occurred in weeks‐long bursts of events. A short‐term transient deformation event is observed in the GPS time series spanning a tremor burst in September 2010. The time‐dependent slip modeling of this Mw=6.9 subevent shows that it migrated along strike with tremor at speeds of ∼8 km/day and with slip rates of ∼3 mm/day. It released 9% of the 5‐year transient event total moment in 1.4% of its duration. The decomposition of GPS time series relative to tremor times during the whole 5‐year transient event shows that GPS site velocities were on average three to six times higher during tremor bursts than in between, suggesting that slip pulses are generally associated with tremor bursts. This inference is strengthened by the decomposition of the GPS time series after the 5‐years‐long deformation event, during which the plate interface is being loaded in between the short‐duration events and slips at times of tremor bursts. The 5‐years‐long transient deformation event could either represent a cluster of short‐term events or be the sum of short‐term ETS events and a smooth long‐term slip event located updip.
Attadance system in the teaching and learning process using RFID smart cards

The use of Electronic Cards for Student Attadance ’aims to design and build a system based on Arduino Uno microcontrollers and RFID modules. The system is expected to be able to facilitate lecturers in conducting attendance, reduce the attendance habits carried out by students, and increase the intensity of the use of student sign cards. The Attadance System based on the Arduino Uno microcontroller and RFID module is designed and built through several stages, namely: (1) analysis along with identification of the needs of components and other auxiliary equipment that support the success of system design; (2) designing components and mechanical design as component containers; (3) system implementation; (4) system testing and overall system evaluation. System testing shows the results in the form of a system performance that shows the student’s name, student’s master number, time of entry and when the student exits from the room. This system is equipped with a person counting device in the room, so it can be ascertained that there will not be an incident entrusted because the number of cards scanned can be matched with the number of students in the room.
Is universal ultrasound screening for developmental DDH in newborns better than physical examination screening or selective ultrasound screening?

Universal ultrasound screening leads to about five fewer infants out of 10,000 with delayed diagnosis of developmental dysplasia of the hip (DDH) and is associated with increased treatment rates compared with selective screening. However, long-term outcomes are similar (SOR: B, systematic review of randomized controlled trial and cohort study). Universal ultrasound screening and Ortolani testing find a similar number of hips with DDH, but ultrasound screening results in considerably more patients with abnormal findings who do not end up having DDH (SOR:B, longitudinal study). Universal ultrasound screening for DDH is not recommended, but selective ultrasound screening can be considered in infants six weeks to six months of age with risk factors (SOR: C, expert opinion).

The social convoys of affordable senior housing residents: Fellow residents and “Time Left”

ABSTRACT Living in an affordable senior housing site is a viable option for older adults who want to age in a community setting. Affordable senior housing is subsidized housing provided in the United States by the federal government’s Department of Housing and Urban Development (HUD). Such housing is available to people 62-years-of-age and older whose income level is low enough to merit federal assistance. The current study assessed the social convoys of 32 residents of one affordable senior housing site, with interest in the number of co-residents included in participants’ social convoys, as well as participants’ levels of social isolation and loneliness. In the present study, family relationships made up the largest proportion of residents’ social convoys (38.6%); however, co-residents made up 26% of participants’ social convoys. There was a positive correlation between the number of years that participants had lived at the affordable senior housing site and the percent of co-residents in their social convoys r = . 39, p = . 03. These findings suggest that under certain conditions older adults are willing to invest in creating new relationships with co-residents in congregate settings. The implications of these findings are explored.
