Focused low-energy extracorporeal shock waves with distally symmetric polyneuropathy (DSPNP): A pilot study
Authors: Lohse-Busch H. , Marlinghaus E. , Reime U. , Möwis U.
Published: December 2019

Background:

Incidental observations led to the question whether ESWT could alleviate the still difficult-to-improve symptoms of DSPNP.

Methods:

In a pilot study, out of an original 24 patients with DSPNP, 10 patients with diabetes mellitus were excluded because of their inhomogeneous performances. Of the 14 patients remaining, 6 received one sham treatment at the beginning. All 14 patients were then treated with ESWT to the soles of the feet using the Duolith® shock wave generator (Storz Medical) 3 times weekly for 2 weeks. The assessments were carried out before and after the sham treatment, the first ESWT (question: before and after the first ESWT or only after?) and after 2, 4 and 8 weeks.

Results:

The placebo treatment did not influence pain or paraesthesia. After the 2 weeks of ESWT, intensity decreased from 100% to 23.6%, rising again after 8 weeks to 45.7% of the original state (p < 0.01). The placebo treatment did however have a great effect on walking abilities. The results of ESWT did not become significant until the 8th week. Step length improved by 14.6% (p < 0.001), walking speed by 24.8% (p < 0.001) and time of dual support during the stance phase of the gait declined by 12.2% (p < 0.009).

Conclusions:

Despite the small number of cases, it appears that ESWT can alleviate some of the symptoms of DSPNP.

The purpose of this study was to: (1) define perceptual speech characteristics of idiopathic Parkinson disease (IPD) across 35 speech dimensions adapted from Darley et al. [19] and grouped under six speech-sign clusters (respiration, phonation, resonance, articulation, prosody and rate); (2) examine the effects of levodopa on the 35 perceptual speech dimensions and speech-sign clusters; and (3) to compare the relative effectiveness of levodopa on global motor functioning vs. speech production.

Sixteen patients with IPD read the ‘Grandfather Passage’ both ‘on’ and ‘off’ levodopa. Three blinded speech-language pathologists performed perceptual speech analyses using a seven-point scale. The diagnosis of IPD was made by a movement disorders fellowship trained neurologist who applied UK Brain bank criteria and administered the Unified Parkinson Disease Rating Scale.

Concordant with previous studies, the results of this experiment indicated that IPD disrupted multiple speech production subsystems, with prosody being the most severely affected domain. The perceptual dimensions that were most severely affected included: (1) sound imprecision; (2) mono-loudness; (3) mono-pitch; (4) reduced stress and (5) harsh voice. No significant differences were obtained between medicated states (‘on’/‘off’) for any of the 35 individual speech dimensions and speech-sign clusters. Global motor function significantly improved following dopaminergic medications.
Self-generated expressions of residual complaints following brain injury
Authors: Brown D. , Rose D. , Lyons E.
Published: December 2019

Following brain injury there is often a prolonged period of deteriorating psychological condition, despite neurological stability or improvement. This is presumably consequent to the remission of anosognosia and the realisation of permanently worsened status. This change is hypothesised to be directed partially by the socially mediated processes which play a role in generating self-awareness and which here direct the reconstruction of the self as a permanently injured person. However, before we can understand this process of redevelopment, we need an unbiassed technique to monitor self-awareness.

Semi-structured interviews were conducted with 30 individuals with long-standing brain injuries to capture their spontaneous complaints and their level of insight into the implications of their difficulties. The focus was on what the participants said in their own words, and the extent to which self-knowledge of difficulties was spontaneously salient to the participants. Their responses were subjected to content analysis. Most participants were able to say that they had brain injuries and physical difficulties, many mentioned memory and attentional problems and a few made references to a variety of emotional disturbances.

Content analysis of data from unbiassed interviews can reveal the extent to which people with brain injuries know about their difficulties. Social constructionist accounts of self-awareness and recovery are supported.
Sentence planning following traumatic brain injury
Authors: Ellis Charles , Peach Richard K.
Published: December 2019

Background:

Current descriptions of the language problems following traumatic brain injury (TBI) generally emphasize evaluating discourse production and explaining the observed outcomes in terms of disruptions to executive processes. The notion of sentence production impairments at the sentence level has generally been ignored. To respond to this issue, we examined patterns of intrasentential pausing and sentence planning during sentences produced by normal and TBI speakers.

Methods:

Seven individuals with TBI functioning at Rancho Level V-VI and seven age-matched controls participated in this pilot experiment. Group performances were compared for pause time and verbal initiation time during the production of sentences varying in syntactic complexity under two conditions (reading and repetition).

Results:

Significant group differences were observed in pausing during both conditions. Pausing patterns of the participants with TBI were strongly correlated with the syntactic complexity of sentences. No significant group differences were observed on verbal initiation time of repeated sentences, although increased initiation times were present among the TBI participants.

Conclusions:

These findings of this pilot project suggest that the deficits in language production following TBI may include specific impairments to sentence planning. This evidence suggests that the language profile of TBI may be one of both microlinguistic and macrolinguistic impairments.

Short-term effects of vibration therapy on motor impairments in Parkinson's disease
Authors: King Lauren K. , Almeida Quincy J. , Ahonen Heidi
Published: December 2019

Recent studies have suggested that vibration therapy may have a positive influence on motor symptoms in individuals with Parkinson's disease (PD). However, quantitative evidence of these benefits is scarce, and the concept of “whole-body” vibration in these studies is vague. The objectives of the current study were to evaluate the influence of vibration on motor symptoms and functional measures in PD by delivering sound waves to the entire body. We delivered whole body sound wave vibration to 40 individuals with PD using a Physioacoustic Chair, a piece of equipment with speakers spaced throughout the chair permitting a series of programmed low frequency sound waves through the body. Using a parallel cross-over design we utilized the Unified Parkinson's Disease Rating Scale (UPDRS), quantitative gait assessments, and a grooved pegboard for upper limb control. Improvements were seen in all symptom, motor control and functional outcome measures at the time of assessment. Specifically, a significant decrease in rigidity, and tremor were shown, as well as a significant increase in step length and improved speed on the grooved pegboard task. Results of this initial investigation provide support for vibration therapy as a non-pharmacological treatment alternative. Long-term benefits of vibration therapy will require further research.
Corpus callosum injury in patients with diffuse axonal injury: A diffusion tensor imaging study
Authors: Chang Min Cheol , Jang Sung Ho
Published: December 2019

Little is known about diffusion tensor image (DTI) findings of corpus callosum (CC) injury in patients with diffuse axonal injury (DAI). In the present study, we investigated the presence and extent of CC injury in patients with DAI. Twenty patients with DAI and 20 age-and sex-matched normal healthy controls subjects were recruited. Patients were divided into two groups according to the presence of a CC lesion on conventional brain MRI, namely, the CC (+) group (8 patients) and the CC (-) group (12 patients). DTIs were acquired using a sensitivity-encoding head coil at 1.5 T. The CC was divided into six mid-sagittal segments: the genu, rostral midbody, anterior midbody, posterior midbody, isthmus, and splenium. Fractional anisotropies (FA) and apparent diffusion coefficients (ADCs) were measured. FA values of all CC segments in DAI patients were significantly lower than those of controls ( p < 0.001); whereas ADC values were either similar or marginally higher. FA values of the six sagittal segments in the CC (-) and (+) groups were significantly lower than those of controls, and ADC values were slightly higher, or showed no change. CC lesions may be present in DAI patients, irrespective of detection on conventional brain MRI. The authors suggest the probability that in cases of corpus callosum injury, DTI can offer a powerful means of detecting DAI.
The relation between fornix injury and memory impairment in patients with diffuse axonal injury: A diffusion tensor imaging study
Authors: Chang Min Cheol , Kim Seong Ho , Kim Oh Lyong , Bai Dai Seg , Jang Sung Ho
Published: December 2019

Little is known about the relation between fornix injury and memory impairment in diffuse axonal injury (DAI). In the current study, we attempted to investigate fornix injury in patients with memory impairment following DAI, using diffusion tensor imaging (DTI). Nine patients with DAI and nine age-and sex-matched control subjects were recruited. The DTIs were acquired using a sensitivity-encoding head coil on a 1.5 T. Five regions of interest (ROI) were drawn manually on a color fractional anisotropy (FA) map: two ROIs for each column, one ROI for the body, and two ROIs for each crus. The FA and apparent diffusion coefficient (ADC) were measured in each of the ROIs. Cognitive function was evaluated using the Memory Assessment Scale, Wechsler Intelligence Scale, and Mini-Mental State Exam. In the DAI group, the FA value in the fornix body was significantly decreased compared with that of the control group. In contrast, we did not find significant differences in the column and crus of the fornix. Among all of the cognitive function scales, only the Memory Assessment Scale scores were significantly correlated with the FA values of the fornix body in the DAI group. We found that memory impairment in patients with DAI is closely related to neuronal injury of the fornix body among the three fornix regions that we assessed. DTI could be useful in the evaluation of patients with memory impairment following DAI.
Optic radiation injury following traumatic epidural hematoma: Diffusion tensor imaging study
Authors: Kwon Hyeok Gyu , Jang Sung Ho
Published: December 2019

Little is known about optic radiation (OR) injury in patients with traumatic brain injury (TBI). We report on a patient who showed an OR injury on diffusion tensor imaging (DTI) following traumatic epidural hematoma (EDH). A 38 year-old man with TBI and 7 age-matched normal subjects were enrolled in this study. The patient had fallen down stairs while in an alcohol intoxicated state. He underwent a craniotomy following diagnosis of traumatic EDH in the left temporo-parietal lobe on brain CT. He complained of right bilateral homonymous hemianopsia, which was confirmed on the Humphrey visual field test. No lesion on the left OR was observed during brain MRI. We were not able to reconstruct the fiber tractography for the left OR in this patient. We found that the left OR had been injured most severely around the midportion between the lateral geniculate body and occipital pole. We determined that DTI would be a useful technique for detection of an OR injury in patients with TBI. Therefore, we believe that DTI should be performed along with conventional brain MRI for patients with visual field defects following TBI.
Virtual realities as motivational tools for robotic assisted gait training in children: A surface electromyography study
Authors: Schuler Tabea , Brütsch Karin , Müller Roland , van Hedel Hubertus J.A. , Meyer-Heim Andreas
Published: December 2019

Patient's active cooperation is essential to achieve good outcome in pediatric rehabilitation. Therefore, virtual environments were developed to enhance robotic assisted gait training. The purpose of this study was to evaluate virtual realities as motivational tools during robotic assisted gait training with children in the pediatric Lokomat®. Nine children with different gait disorders and eight healthy children participated in the study. Muscular effort of the lower leg was assessed by surface electromyography during a randomly designed training protocol with virtual realities. Self reported motivation was investigated with two questionnaires. Comparisons were drawn through repeated measurement Analysis of Variance and paired-t-tests. The logarithmic transformed data showed that the electromyographic activity output in both groups was significantly higher during tasks with virtual realities than during normal walking conditions. These results support that virtual realities seem to be efficient motivational tools to increase children's muscular effort in the pediatric Lokomat®. The gaming aspect of virtual realities keeps children highly engaged during repetitive tasks.
Electrical stimulation improves gait in children with spastic diplegic cerebral palsy
Authors: AlAbdulwahab Sami Saleh
Published: December 2019

Background:

Electrical stimulation (ES) of proximal muscles during gait training has not previously been reported as a management option for improving muscle tone and gait in spastic diplegic children.

Objective:

To investigate the effects of simultaneous continuous ES of both hip abductors and adductors during walking on muscle tone, knee alignment and gait characteristics in children with spastic diplegic cerebral palsy (CP).

Subject:

Three groups of children participated in this project: the study group, consisting of 17 ambulant children with spastic diplegic CP; a control group of 15 ambulant children with spastic diplegic CP; and another control group, with 17 healthy children.

Methods:

The study group underwent two different ES management programs. The first was a one-time trial management program that involved ongoing ES of bilateral hip adductor and abductor muscles at the sensory and motor levels, respectively, during walking for a predetermined distance. The second ES program lasted for one week and involved 15 minutes of ongoing ES of bilateral hip adductor and abductor muscles at the sensory and motor levels, respectively, during walking for three sessions a day for the week.

Results:

Marked improvement in gait performance ( p < 0.001), muscle tone ( p < 0.01) and knee position of the study group was observed.

Conclusion:

ES to the hip adductor and abductor muscles simultaneously at the sensor and motor levels, respectively, improved gait in spastic diplegic CP children.
The effect of variable gait modes on walking parameters among children post severe traumatic brain injury and typically developed controls
Authors: Katz-Leurer Michal , Rotem Hemda , Keren Ofer , Meyer Shirley
Published: December 2019

The goal of the present study was to assess the effect of various walking modes on dynamic gait characteristics and to evaluate the possible differences in the adaptation reactions between children post severe traumatic brain injury (TBI) and typically developed (TD) controls.

Methods:

Thirteen children post severe TBI, mean of 3.5 years post trauma, independent walkers, with a walking velocity > 1.1 m/sec, and 15 TD controls participated in this study. Ages were 7–13 years. Gait speed, step time and length and step time and length variability were assessed by an electronic walkway. The children completed three cycles on the walkway for each of the following situations: comfortable walking, walking as fast as possible, as slow as possible and walking on a straight line.

Results:

Despite a similar walking performance while walking at a “regular” speed, children post severe TBI exhibit a significantly reduced range of walking speeds (73–154 cm/sec), about half, as compared to TD children (54–193 cm/sec) across the study assignments. In addition, while “walking on a straight line” children post TBI walk slower, with increased step variability as compared to their peers.

Conclusion:

Children post severe traumatic brain injury may achieve independent walking at a comparable rate to typically developed controls; however their impairments will be exacerbated as the demands increase. Since a variety of walking speeds is crucial for independent daily living at any age and for children in particular, and since adequate balance is an inherent element of walking, these issues need repeated assessments and the children should receive appropriate treatment.
Efficacy of therapeutic ultrasound in the treatment of spasticity: A randomized controlled study
Authors: Sahin Nilay , Ugurlu Hatice , Karahan Ali Yavuz
Published: December 2019

The purpose of this study was to investigate the effect of ultrasound (US) on the spasticity occurring in the ankle plantar flexor muscles after a cerebrovascular event. According to the modified Ashworth scale (MAS), the hemiplegic patients with stage 2–3 spasticity on the ankle plantar flexor muscles were enrolled in the study and divided into two groups. Passive stretching exercise was applied to both groups. Additionally, 10-minute US was applied to one of the groups, using the mode of continuous wave of 1.5w/cm2 to the calf muscles before stretching. In order to monitor the efficacy of the treatment in the patients, MAS, Hmax/Mmax ratio, the ankle range of motion (ROM), Functional Independence Measure and Brunnstrom Motor Recovery Stage were evaluated. While a significant recovery was monitored in the MAS and ankle ROM measurements after treatment in both groups, no change was obtained in the other parameters. No significant difference was detected in any of the measurements between the groups. In this study, US treatment applied in combination with the ankle plantar flexor muscles passive stretching exercise was determined to have no effect on the stretching treatment in minimizing the spasticity.
Dissimilar outcomes of apparently similar procedures as a challenge to clinical neurorehabilitation and basic research: When the same is not the same
Authors: Wilms Inge , Mogensen Jesper
Published: December 2019

In the study of the brain and how it adapts to changes or injury, researchers sometimes come across situations where apparently similar types of tests or training do not achieve similar outcome results. This is true, in particular, within the field of computer-based rehabilitation where paper-and-pencil tests and training is converted to computer. This paper raises the attention to the fact that supposedly similar settings may not, in fact, elicit similar results and caution therapists and researchers who work with rehabilitation of brain injury. The paper suggests that the underlying mechanisms behind this may be illuminated by using the REF (Reorganization of Elementary Functions) model and suggests that further research into the use of advanced technologies such as computer-generated virtual reality is required.
The correlation of independency in activities of daily living performance with cognitive status and the intensity of neurological impairment in right-handed stroke patients
Authors: Akbari Shadi , Ashayeri Hassan , Fahimi Malahat Akbar , Kamali Mohamad , Lyden Patrick D.
Published: December 2019

Purpose:

We aimed to investigate whether test performance in neurological and cognitive areas is able to predict daily task performance in stroke patients and if the two selected measures of stroke severity and cognitive function could be used as valid tools to predict functional outcomes after stroke.

Method:

We assessed 27 stroke patients (hemorrhagic and infarct) through Barthel Index (BI), Lowenstein Occupational Therapy Cognitive Assessment (LOTCA) and National Institute of Health Stroke Scale (NIHSS) in the first 6 months after stroke.

Results:

The correlation of intensity of neurological impairment (NIHSS score) and ADL performance (BI score) was significant ( P < 0/05), but we found no relation between general cognitive function (the total score of LOTCA) and individual independence (total score of BI). Although ADL performance areas associated with some cognitive components.

Conclusion:

The dependency after stroke is more affected by physical symptoms of stroke than by cognitive disorders. Moreover, the intensity of neurological impairment could be a better explanation for a patient’s inability to perform basic ADL independently. Low direct relations in total scores of NIHS scale and BI was found, but LOTCA is not appropriate for prediction of independency in basic ADL performance after stroke. Nevertheless, further studies and confirmation are needed.

RFID-enabled Real-Time Location System (RTLS) to improve hospital's operations management: An up-to-date typology
Authors: Bendavid Ygal
Published: December 2019

Recent deployments of Real-Time Location Systems (RTLS) around the world illustrate a key trend in Radio Frequency Identification (RFID) technologies supporting innovative applications within numerous industrial sectors. Managers in charge of implementing RTLS face several challenges when (a) selecting the right active/passive RFID system for their needs; (b) implementing and integrating the system; and (c) leveraging on it, to move from automated object identification to information management and decision-making. Although some information is available to support researchers and practitioners, the existing documentation often focuses on specific aspects of the technology, and much of the information found in the professional literature is not vendor-neutral, resulting in some confusion for decision-makers. This paper clarifies the different technological options presently available on the market and proposes up-to-date typologies for RTLS hardware and software solutions used in hospitals. Findings can help potential adopters select an RTLS that meets their specific needs while highlighting the critical steps and pitfalls at the front end phases of a RTLS implementation project.
Preliminary analysis of warehouse localization systems based on RFID technology
Authors: Scalia Giada La , Aiello Giuseppe , Enea Mario , Micale Rosa
Published: December 2019

In the industrial warehouse design domain, today’s computerized information systems have gained a relevant interest due to the issues related to asset tracking and traceability. In such context, the employment of new information technologies on warehouse management systems has opened new business opportunities due to the sensible price reduction in the last years. This paper focuses on the technical issues related to the realization of wireless localization systems for warehouses, which are necessary for the implementation of random allocation policies, and in particular investigates the opportunities offered by RFID technology in such context. The enforcement of random allocation policies allows to increase the utilization coefficient of warehouses which is a critical issue, for example in refrigerated warehouses for perishable products. In particular, the development of localization systems based on trilateration is here considered, and an experimental model which links the received signal strength to the reading distance has been determined in order to take into account the specific features of the technology employed. A~methodology is hence proposed to overcome the simplifying assumptions theoretical attenuation models rely on, by fitting a mathematical model on experimental observations. The problem of the accuracy level required to locate Stock Keeping Units (SKUs) of fixed dimensions is also considered, resulting in the evaluation of the maximum allowed reading distance. On the basis of the obtained results, the optimal configuration of the fixed infrastructure in terms of the number of antennas and their position is finally defined.
Integrated billing mechanisms in the Internet of Things to support information sharing and enable new business opportunities
Authors: Uckelmann Dieter , Harrison Mark
Published: December 2019

The Internet of Things (IOT) concept and enabling technologies such as RFID offer the prospect of linking the real world of physical objects with the virtual world of information technology to improve visibility and traceability information within supply chains and across the entire lifecycles of products, as well as enabling more intuitive interactions and greater automation possibilities. There is a huge potential for savings through process optimization and profit generation within the IOT, but the sharing of financial benefits across companies remains an unsolved issue. Existing approaches towards sharing of costs and benefits have failed to scale so far. The integration of payment solutions into the IOT architecture could solve this problem. We have reviewed different possible levels of integration. Multiple payment solutions have been researched. Finally we have developed a model that meets the requirements of the IOT in relation to openness and scalability. It supports both hardware-centric and software-centric approaches to integration of payment solutions with the IOT. Different requirements concerning payment solutions within the IOT have been defined and considered in the proposed model. Possible solution providers include telcos, e-payment service providers and new players such as banks and standardization bodies. The proposed model of integrating the Internet of Things with payment solutions will lower the barrier to invoicing for the more granular visibility information generated using the IOT. Thus, it has the potential to enable recovery of the necessary investments in IOT infrastructure and accelerate adoption of the IOT, especially for projects that are only viable when multiple benefits throughout the supply chain need to be accumulated in order to achieve a Return on Investment (ROI). In a long-term perspective, it may enable IT-departments to become profit centres instead of cost centres.
RFID supply chain implementation challenges for short-life products
Authors: Vecchi Alessandra , Brennan Louis
Published: December 2019

The RFID value proposition allows grocery retailers to remain competitive by boosting the supply chain overall efficiency and by generating substantial cost savings. Although these cited benefits are significant, the exact description of how they are attainable in practice has remained vague. Drawing on the preparation and implementation for a RFID pilot in the supply chain for short-life products, this paper discusses the practical issues that one might encounter and that might undermine the successful implementation of RFID. From the findings it emerges that while there are opportunities, there are also some major practical challenges in implementing RFID. These challenges include the placement of the RFID readers, the automation of the tagging process, tagging identification levels (i.e. case/pallet) and issues that are specific to the application. We argue that a fuller understanding and appreciation of these practical challenges informs the academic discourse around RFID and offers a valuable insight to grocery retailers on how to align their technology decisions with their business practices in the attempt to fully reap the benefits of RFID.
RFID based efficient lighting control
Authors: Manzoor Farhan , Linton David , Loughlin Michael , Menzel Karsten
Published: December 2019

The Kyoto Protocol and the European Energy Performance of Buildings Directive put an onus on governments and organisations to lower carbon footprint in order to contribute towards reducing global warming. A key parameter to be considered in buildings towards energy and cost savings is its indoor lighting that has a major impact on overall energy usage and Carbon Dioxide emissions. Lighting control in buildings using Passive Infrared sensors is a reliable and well established approach; however, the use of only Passive Infrared does not offer much savings towards reducing carbon, energy, and cost. Accurate occupancy monitoring information can greatly affect a building's lighting control strategy towards a greener usage. This paper presents an approach for data fusion of Passive Infrared sensors and passive Radio Frequency Identification (RFID) based occupancy monitoring. The idea is to have efficient, need-based, and reliable control of lighting towards a green indoor environment, all while considering visual comfort of occupants. The proposed approach provides an estimated 13% electrical energy savings in one open-plan office of a University building in one working day. Practical implementation of RFID gateways provide real-world occupancy profiling data to be fused with Passive Infrared sensing towards analysis and improvement of building lighting usage and control.
Biased splitting methods of an index structure based on R*-tree for tracing RFID tag locations
Authors: Kim Gihong , Hong Bonghee
Published: December 2019

In RFID systems, it is important to track and trace locations of tags attached to physical objectsin many applications such as automated manufacturing, inventory tracking and supply chain management. Queries for tracing tag locations are among the most challenging requirements in RFID based applications. For efficient query processing, trajectories of tags can be modeled and indexed as a line in a three-dimensional domain, with the axes being the tag identifier, the reader identifier, and the time. In a different way of a moving object index, the ranges of coordinates for each domain are quite different so that the distribution of query regions is biased. Since this biased distribution of query regions produces many overlaps with index nodes, many node accesses are occurred at answering queries. To reduce unnecessary overlaps, the splitting scheme of an index should be changed. Previous indexes for tag trajectories, however, do not consider the biased distribution of query regions. To solve this problem, we propose a new biased splitting method based on R*-tree. For efficient insertion of tag trajectories, our method derives the weighted margin for each node by using weights of each axis and margin of nodes. With the weighted margin, we can choose the subtree which has the minimum cost for inserting trajectories and splitting nodes. Proposed splitting method reduces the cost of region query by reducing overlapped area of query region and MBRs. We also evaluate the performance of our method and compare it with the previous methods. Our experiments show that the index based on the proposed splitting method considerably improves the performance of queries than the index based on the previous methods.
Coverage analysis of RFID indoor localization system for refrigerated warehouses based on 2D-ray tracing
Authors: La Scalia Giada , Aiello Giuseppe , Micale Rosa , Enea Mario
Published: December 2019

Localization systems are becoming an important feature for many RFID-based inventory and warehouse management support tools, due to the ever increasing diffusion of Radio Frequency IDentification (RFID) in logistic processes. RFID-based Location system will allow offering value-added services to logistics operators, where RFID tags can be used for more than just labeling items. This paper proposes a Received Signal Strength (RSS) based positioning system for perishable products equipped with active UHF RFID tags, inside a refrigerated warehouse (4C°). A fundamental problem in the design of RFID based localization system is the evaluation and mapping of the signal attenuation, which depends upon several parameters (fading from obstacles in the transmission path, reflections off surfaces and relative antenna orientation). Such information should be considered in the design phase, where instead simplified theoretical approaches are frequently employed. Theoretical path loss models are however inadequate for a reliable prediction of the signal strength, which significantly affects the accuracy of distance measurement and ultimately the precision of localization. An accurate prediction of the coverage level is hence required for obtaining a reliable design. In this paper, a case study on the design of an RFID localization system is presented, comparing a realistic signal distribution, obtained considering the influence of reflections and refractions, and the theoretical approach based on simple path loss models. Realistic coverage maps are obtained by means of a simulation tool based on 2D ray tracing algorithm.
The Efficacy of Monetary Transmission Mechanism: The Case of the United States
Authors: Alaabed Alaa
Published: December 2019

This paper empirically investigates the effectiveness of monetary policy transmission in the United States from 1975-2010 using the Long-Run Structural Modelling (LRSM) and the techniques of error correction and variance decompositions. The results indicate that the domestic credit and exchange rate channels are relatively effective in influencing the real GDP per capita, and so is inflation-targeting, while the interest rate channel does not appear to play an important role as a monetary transmission mechanism, bearing in mind the interlinkages between the channels. The empirical analysis suggests that policy measures and structural reforms must be targeted accordingly in order to promote the effectiveness of monetary transmission mechanisms in the US and similar countries.

Published: December 2019

The purpose of this paper is to discuss Wakalah contract which is one of the Islamic banking contracts. Therefore, our main study is the implementation of Wakalah in Indonesia. Wakalah in Indonesia has special reference which is Multifinance company (MFC). MFC is an entity of non-bank financial institution conducts business activities to finance goods or services.Therefore, this research is going to discuss how Wakalah is practiced in Indonesia, where Islamic banks appoint MFC as an agent to do service for end user “customer” on behalf of the bank. Consequently, the objective of this paper is to discuss the implementation of Wakalah with Mudharabah and Wakalah with Murabahah by MFC in Indonesia in terms of operation, the potential risks that might be occur and shariah issues in terms of ownership and fee. However, there are particular areas in terms of operation that MFC should improve, as well as, banks have to be aware of its operational way of conducting agreement so banks mitigate any kind of risks or negligence.

O papel do exercí­cio fí­sico como uma estratégia para a melhoria da segurança de voo: foco no controlador de tráfego aéreo
Authors: Gabriel-Costa Daniele , Massaferri Renato de Oliveira
Published: December 2019

Introdução: Os controladores de tráfego aéreo (CTA) exercem atividade laboral de grande sobrecarga mental e física, e a prática regular de exercícios físicos pode ser uma alternativa eficaz e econômica nesse contexto. Objetivo: Discutir os efeitos promovidos pelo treinamento físico sobre os sintomas apresentados pelos CTA. Métodos: Revisão sistemática com seleção nas bases Pubmed, Scielo, Lilacs, Scopus. Resultados: Não foram encontrados trabalhos que envolvessem diretamente os CTA. No entanto, notou-se semelhança entre os sintomas apresentados por eles e outros profissionais com atividade de turno invertido/rotacional. Os trabalhos que apresentaram intervenções com treinamento físico nesses indivíduos demonstraram que os principais sintomas provocados pela atividade dos CTA podem ser mitigados, apresentando-se como uma estratégia interessante. Conclusão: O treinamento físico pode contribuir para mitigar os efeitos deletérios da atividade laboral dos CTA.
Análise da atividade eletromiográfica dos músculos extensores da perna de jogadoras de voleibol feminino
Authors: Borin Sergio Henrique
Published: December 2019

Na prática clí­nica, observa-se o crescimento de lesões esportivas, decorrentes de desequilí­brios musculares. O objetivo deste trabalho foi analisar a atividade eletromiográfi ca (EMG) dos músculos do quadrí­ceps femoral, numa contração isométrica voluntária máxima de extensão da perna em dois ângulos distintos. Foram analisadas 12 jogadoras de voleibol e 12 sedentárias. Para análise da EMG utilizou-se a envoltória (EN) do sinal, analisados através do teste de Wilcoxon (p < 0,05). Os resultados da EN intragrupos evidenciaram que o recrutamento de todos os músculos foi maior a 90º em relação í  30º, independente da dominância e grupo. Já intergrupos, os resultados demonstraram ocorrer diferenças no recrutamento das atletas quando comparados com as sedentárias, sendo os músculos VMO, VLO, RF e VLL tanto 30º como 90º, independente da dominância. Os resultados Intragrupos demonstram que o músculo VMO foi mais ativo, seguido do VLO, RF e VLL, para sedentárias e VMO, VLL e RF e VLO no grupo atletas.Palavras-chave: eletromiografia, treinamento, desequilí­briosÂ  musculares, fisioterapia.
Comparação de valores de testes de força externa máxima do quadrí­ceps femoral
Authors: Candotti Cláudia Tarragô
Published: December 2019

O objetivo deste estudo foi comparar os valores de força máxima obtidos com os testes de Contração Voluntária Máxima Isométrica (CVMI) e de Uma Repetição Máxima (1RM) com os valores de força máxima preditos pelo teste de Carga por Repetições Máximas (CRM) durante o movimento de extensão de joelho. Dez indiví­duos do sexo masculino realizaram os testes CVMI, 1RM e CRM uma única vez. Os valores de força foram submetidos a uma análise de variância Oneway para verificar as diferenças entre os testes. Os resultados demonstraram que não existe diferença significativa (p = 0,273) entre os valores de força, sugerindo que o teste de CRM é adequado para estimar a força máxima externa do quadrí­ceps femoral, podendo substituir os testes de 1RM e de CVMI, em situações em que estes não são apropriados, como por exemplo, nos protocolos de fadiga muscular localizada em indiví­duos com dor muscular.Â Palavras-chave: force, prediction, femoris quadriceps, maximal tests.Â Â
