Fine motor outcomes in preschool children who receive occupational therapy services.

OBJECTIVE
This study examined preschool children's acquisition of fine motor skills and functional performance when occupational therapy services are included as part of the educational program. It also investigated the relationships among fine motor skills and functional performance in self-care, mobility, and social function.


METHOD
Twenty-six preschool children who received weekly occupational therapy were studied. Measurements of their in-hand manipulation, tool use, eye-hand coordination, grasping strength, and functional performance in self-care, mobility, and social function were taken at the beginning and end of the school year.


RESULTS
Raw and scaled scores showed significant improvements in all skill areas; standard scores showed slight improvement in eye-hand coordination and mobility function. Correlations of the motor skill tests with the functional performance scales using year-end data revealed significant correlations for in-hand manipulation, eye-hand coordination, and grasping strength with self-care function and mobility.


CONCLUSIONS
The results demonstrate the level of change that occurs in fine motor skill and self-care, mobility, and social function during the course of the school year for preschoolers with moderate fine motor delays. The relationships found in the year-end testing imply that performance in underlying fine motor skills as the focus of occupational therapy intervention is associated with self-care and mobility function.
The Warwick-Edinburgh Mental Well-being Scale (WEMWBS): development and UK validation

BACKGROUND
There is increasing international interest in the concept of mental well-being and its contribution to all aspects of human life. Demand for instruments to monitor mental well-being at a population level and evaluate mental health promotion initiatives is growing. This article describes the development and validation of a new scale, comprised only of positively worded items relating to different aspects of positive mental health: the Warwick-Edinburgh Mental Well-Being Scale (WEMWBS).


METHODS
WEMWBS was developed by an expert panel drawing on current academic literature, qualitative research with focus groups, and psychometric testing of an existing scale. It was validated on a student and representative population sample. Content validity was assessed by reviewing the frequency of complete responses and the distribution of responses to each item. Confirmatory factor analysis was used to test the hypothesis that the scale measured a single construct. Internal consistency was assessed using Cronbach's alpha. Criterion validity was explored in terms of correlations between WEMWBS and other scales and by testing whether the scale discriminated between population groups in line with pre-specified hypotheses. Test-retest reliability was assessed at one week using intra-class correlation coefficients. Susceptibility to bias was measured using the Balanced Inventory of Desired Responding.


RESULTS
WEMWBS showed good content validity. Confirmatory factor analysis supported the single factor hypothesis. A Cronbach's alpha score of 0.89 (student sample) and 0.91 (population sample) suggests some item redundancy in the scale. WEMWBS showed high correlations with other mental health and well-being scales and lower correlations with scales measuring overall health. Its distribution was near normal and the scale did not show ceiling effects in a population sample. It discriminated between population groups in a way that is largely consistent with the results of other population surveys. Test-retest reliability at one week was high (0.83). Social desirability bias was lower or similar to that of other comparable scales.


CONCLUSION
WEMWBS is a measure of mental well-being focusing entirely on positive aspects of mental health. As a short and psychometrically robust scale, with no ceiling effects in a population sample, it offers promise as a tool for monitoring mental well-being at a population level. Whilst WEMWBS should appeal to those evaluating mental health promotion initiatives, it is important that the scale's sensitivity to change is established before it is recommended in this context.
Economic cost analysis of hybrid renewable energy system using HOMER

This paper deals with the optimal cost analysis of hybrid renewable energy system (HRES). The optimal cost analysis of HRES is done using Hybrid Optimization Model for Electric Renewable (HOMER). The HOMER energy modeling software is a powerful tool for designing and analyzing hybrid power systems, which contain a combination of conventional generators, cogeneration, wind turbines, solar photovoltaic's, hydropower, batteries, fuel cells, hydropower, biomass and other inputs. It is currently used all over the world by tens of thousands of people. HRES provides the electrical power for a remote located area. In this paper work, real time optimal cost analysis of HRES is done based on the load profile, solar radiation and wind speed which was collected from Mandapam in Ramanathapuram District, Tamil Nadu in India. HOMER is used here to optimize the system based upon the Total Net Present Cost (TNPC). Moreover, the optimization of system is obtained by varying the sensitivity variables like solar radiation, wind speed etc. Cash flow summary of the HRES system is obtained which will be useful for the optimal cost allocation of each individual component present in the system.
Increasing Returns and the Design of Interest Rate Rules

We introduce increasing returns to scale into an otherwise standard New Keynesian model with capital, and study the determinacy and E-stability of Taylor-type interest rate rules. With very mild increasing returns supported by empirical research, the conventional wisdom regarding the design of interest rate rules can be overturned. In particular, the "Taylor principle" no longer guarantees either determinacy or E-stability of the rational expectations equilibrium.
Integrating MQTT and ISO/IEEE 11073 for health information sharing in the Internet of Things

The Internet of Things (IoT) paradigm allows small and resource constrained devices to send data through complex networks like the Internet. Bringing the IoT paradigm to the healthcare area, we can expand the connected health vision, enabling new Personal Health Devices (PHD) to share health information directly through the Internet. In this paper we explore the use of the MQTT (Message Queue Telemetry Transport) lightweight protocol together with the ISO/IEEE 11073 standard. We present new ways of connecting PHDs in home networks and the Internet by the use of MQTT Brokers, which will reduce the amount of data traffic.

Multimodal Memory Modelling for Video Captioning

Video captioning which automatically translates video clips into natural language sentences is a very important task in computer vision. By virtue of recent deep learning technologies, video captioning has made great progress. However, learning an effective mapping from the visual sequence space to the language space is still a challenging problem due to the long-term multimodal dependency modelling and semantic misalignment. Inspired by the facts that memory modelling poses potential advantages to longterm sequential problems [35] and working memory is the key factor of visual attention [33], we propose a Multimodal Memory Model (M) to describe videos, which builds a visual and textual shared memory to model the longterm visual-textual dependency and further guide visual attention on described visual targets to solve visual-textual alignments. Specifically, similar to [10], the proposed M attaches an external memory to store and retrieve both visual and textual contents by interacting with video and sentence with multiple read and write operations. To evaluate the proposed model, we perform experiments on two public datasets: MSVD and MSR-VTT. The experimental results demonstrate that our method outperforms most of the stateof-the-art methods in terms of BLEU and METEOR.
The Effects of Acute Tryptophan Depletion on Reactive Aggression in Adults with Attention-Deficit/Hyperactivity Disorder (ADHD) and Healthy Controls

BACKGROUND
The neurotransmitter serotonin (5-HT) has been linked to the underlying neurobiology of aggressive behavior, particularly with evidence from studies in animals and humans. However, the underlying neurobiology of aggression remains unclear in the context of attention-deficit/hyperactivity disorder (ADHD), a disorder known to be associated with aggression and impulsivity. We investigated the effects of acute tryptophan depletion (ATD), and the resulting diminished central nervous serotonergic neurotransmission, on reactive aggression in healthy controls and adults with ADHD.


METHODOLOGY/PRINCIPAL FINDINGS
Twenty male patients with ADHD and twenty healthy male controls were subjected to ATD with an amino acid (AA) beverage that lacked tryptophan (TRP, the physiological precursor of 5-HT) and a TRP-balanced AA beverage (BAL) in a double-blind, within-subject crossover-study over two study days. We assessed reactive aggression 3.25 hours after ATD/BAL intake using a point-subtraction aggression game (PSAG) in which participants played for points against a fictitious opponent. Point subtraction was taken as a measure for reactive aggression. Lowered rates of reactive aggression were found in the ADHD group under ATD after low provocation (LP), with controls showing the opposite effect. In patients with ADHD, trait-impulsivity was negatively correlated with the ATD effect on reactive aggression after LP. Statistical power was limited due to large standard deviations observed in the data on point subtraction, which may limit the use of this particular paradigm in adults with ADHD.


CONCLUSIONS/SIGNIFICANCE
Together with previous findings, the data provide preliminary evidence of an inverse association between trait-impulsivity and the ATD effect on reactive aggression after LP (as assessed by the PSAG) in patients with ADHD and that this relationship can be found in both adolescents and adults. Because of limited statistical power larger sample sizes are needed to find main effects of ATD/BAL administration on reactive aggression in adults with ADHD.
Vertebrae Detection and Labelling in Lumbar MR Images

We describe a method to automatically detect and label the vertebrae in human lumbar spine MRI scans. Our contribution is to show that marrying two strong algorithms (the Deformable Part Model (DPM) object detector of Felzenszwalb et al. [9], and inference using dynamic programming on chains) together with appropriate modelling, results in a simple, computationally cheap procedure, that achieves state-of-the-art performance. The training of the algorithm is principled, and heuristics are not required. The detections are performed in all slices of a sagittal scan. The method is evaluated quantitatively on a dataset of 371 MRI scans, and it is shown that the method copes with pathologies such as scoliosis, joined vertebrae, deformed vertebrae and disks, and imaging artifacts. We also demonstrate that the same method is applicable (without retraining) to CT scans.
Preanalytical quality improvement: from dream to reality.

Abstract Laboratory diagnostics (i.e., the total testing process) develops conventionally through a virtual loop, originally referred to as "the brain to brain cycle" by George Lundberg. Throughout this complex cycle, there is an inherent possibility that a mistake might occur. According to reliable data, preanalytical errors still account for nearly 60%-70% of all problems occurring in laboratory diagnostics, most of them attributable to mishandling procedures during collection, handling, preparing or storing the specimens. Although most of these would be "intercepted" before inappropriate reactions are taken, in nearly one fifth of the cases they can produce inappropriate investigations and unjustifiable increase in costs, while generating inappropriate clinical decisions and causing some unfortunate circumstances. Several steps have already been undertaken to increase awareness and establish a governance of this frequently overlooked aspect of the total testing process. Standardization and monitoring preanalytical variables is of foremost importance and is associated with the most efficient and well-organized laboratories, resulting in reduced operational costs and increased revenues. As such, this article is aimed at providing readers with significant updates on the total quality management of the preanalytical phase to endeavour further improvement for patient safety throughout this phase of the total testing process.
A distributed trust model

The widespread use of the Internet signals the need for a better understanding of trust as a basis for secure on-line interaction. In the face of increasing uncertainty and risk, users must be allowed to reason flectively about the trustworthiness of on-line entities. In this paper, we outline the shortcomings of current security approaches for managing trust and propose a model for trust, based on distributed recommendations.
Evaluation of Optimal Machining Parameters for Turning by Using Genetic Algorithm

The experimental work for investigating and optimisation the surface roughness in Al6061 material by using cnc turning machine Aluminium 6061 has the major application in vehicle and automobile parts so we have taken aluminium 6061 for conduct the turning process. Surface roughness means the surface irregulars that were found in the workpiece. Design of experiments is used to select the different level of input parameter based on L9 orthogonal the levels of parameter are fixed for the output responses A circular cross section of aluminium 6061 have been machined for required dimensions by centre lathe. Then the experimental work was conducted on cnc turning machine. The surface roughness tester is used to calculate the surface roughness. The taguchi method is used to calculate the predicted result the regression equation from the taguchi method is used for calculate the predicted values in our work. The genetic algorithm is used for optimisation of experimental values. The feed rate is the most dominate factor affecting the surface roughness.
Increased plasma levels of total homocysteine but not asymmetric dimethylarginine in Hispanic subjects with ischemic stroke FREC-VI sub-study.

BACKGROUND AND PURPOSE
  Despite sharing some metabolic and pathological mechanisms, the reported association between total homocysteine (tHcy), asymmetric dimethylarginine (ADMA) and stroke remains controversial, particularly in Hispanic populations from developing countries in which genetic, socioeconomic, and nutritional factors are different to those described in developed countries. Our objectives were to determine the relationships of these factors to stroke and to each other independent of other cardiovascular risk factors, and to explore potential sex differences.


METHODS
This national (Colombia) multicenter case-control study included 238 cases and 238 controls to evaluate traditional and emerging risk factors for ischemic stroke including tHcy and ADMA plasma levels.


RESULTS
The median plasma levels of tHcy were 8.48 μM for controls and 10.01 μM for cases (P<0.0001). Plasma levels of tHcy between 12 and 50μM were considered moderate hyperhomocysteinemia (HtHcy). There were no differences in plasma ADMA concentration between groups (P=0.40). Plasma levels of ADMA and creatinine were not correlated (P=0.47). After adjusting for confounding factors, the presence of HtHcy was strongly associated with stroke (OR 8.97; P<0.0001). The adjusted association between HtHcy and stroke in men (OR 9.98) was comparable to that in women (OR 8.98) (P=0.41).


CONCLUSIONS
In this Hispanic population, with relatively normal renal function, plasma levels of tHcy but not ADMA were associated with stroke independent of other cardiovascular risk factors.
From Audio to Semantics: Approaches to End-to-End Spoken Language Understanding

Conventional spoken language understanding systems consist of two main components: an automatic speech recognition module that converts audio to a transcript, and a natural language understanding module that transforms the resulting text (or top N hypotheses) into a set of domains, intents, and arguments. These modules are typically optimized independently. In this paper, we formulate audio to semantic understanding as a sequence-to-sequence problem [1]. We propose and compare various encoder-decoder based approaches that optimize both modules jointly, in an end-to-end manner. Evaluations on a real-world task show that 1) having an intermediate text representation is crucial for the quality of the predicted semantics, especially the intent arguments and 2) jointly optimizing the full system improves overall accuracy of prediction. Compared to independently trained models, our best jointly trained model achieves similar domain and intent prediction F1 scores, but improves argument word error rate by 18% relative.
QoS-Aware Proportional Fair Packet Scheduling with Required Activity Detection

In this paper, a QoS-aware packet scheduler based on the proportional fair principle is proposed and studied. The new scheduler includes robust estimation of required scheduling activity for a user to meet the QoS requirements and takes into account the cell load and individual user conditions. A framework for distributing capacity between best-effort and QoS users is embedded in the scheduling algorithm. For a given QoS target and a WCDMA/HSDPA system, the scheduler provides around 40% user capacity gain compared to the well-known QoS-aware proportional fair scheduler based on barrier function scaling. While being better at guaranteeing QoS compared to the reference scheduler, it simultaneously provides orders of magnitude larger gain in what throughput is delivered to best- effort users in a mixed-service scenario. A main advantage of the scheduler is its simplicity and inherent robustness which makes it easy to configure in a multi-user/service environment.
A novel and provably secure authentication and key agreement scheme with user anonymity for global mobility networks

Ubiquitous networks support the roaming service for mobile communication devices. The mobile user can use the services in the foreign network with the help of the home network. Mutual authentication plays an important role in the roaming services, and researchers put their interests on the authentication schemes. Recently, in 2016, Gope and Hwang found that mutual authentication scheme of He et al. for global mobility networks had security disadvantages such as vulnerability to forgery attacks, unfair key agreement, and destitution of user anonymity. Then, they presented an improved scheme. However, we find that the scheme cannot resist the off-line guessing attack and the de-synchronization attack. Also, it lacks strong forward security. Moreover, the session key is known to HA in that scheme. To get over the weaknesses, we propose a new two-factor authentication scheme for global mobility networks. We use formal proof with random oracle model, formal verification with the tool Proverif, and informal analysis to demonstrate the security of the proposed scheme. Compared with some very recent schemes, our scheme is more applicable. Copyright © 2016 John Wiley & Sons, Ltd.
Beam Transmission Of Ultra Short Waves: An Introduction To The Classic Paper By H. Yagi

I am delighted to give an introduction to the classic paper by Prof. H. Yagi describing the Yagi–Uda array antenna [1]. As is generally understood today, the Yagi–Uda antenna was developed by H. Yagi and S. Uda at Tohoku Imperial University in Sendai, Japan, and was first reported in a paper jointly authored by Yagi and Uda and published in English in theProceedings of the Imperial Academy in Japan in February 1926 [2]. As reported in articles by Prof. G. Sato on the history of the Yagi–Uda antenna [3]–[4], a series of papers further describing this antenna appeared in the Japanese literature from 1926 to 1929, and the antenna was patented by Yagi in Japan in March 1926. The work received little attention outside of Japan, however, until 1928, when Yagi visited the United States and gave papers at meetings of the Institute of Radio Engineers (IRE) in New York, Washington, D.C., and Hartford, CT. The subject of these talks was published by Yagi in the PROCEEDINGS OF THEIRE in 1928 [1], and this paper is credited with bringing the concept of the Yagi–Uda array to a worldwide audience. According to the public comments published with this paper, J. H. Dellinger, chief of the Radio Division of the Bureau of Standards in Washington, said, “I have never listened to a paper that I felt so sure was destined to be a classic.” He was certainly correct in his conclusion. In this introduction to the reprinting of Yagi’s classic paper, we will describe the Yagi–Uda array antenna and discuss its significance in terms of both its historical context and its impact on later antenna development. We will also review the highlights of the paper and discuss some of the developments related to Yagi–Uda arrays that have occurred since its publication. In fact, the Yagi–Uda antenna has generated interest that continues to this day, in terms of theoretical analysis and optimization, practical applications,
RFID-Based RTLS for Improvement of Operation System in Container Terminals

Shipping companies consider most of the ship turnaround time as a critical factor when selecting a calling port for reducing costs. Container terminal operator tries to improve the port quality of service requested by a shipping line to maximize the productivity of container terminals. Therefore, this thesis proposes RFID (radio frequency identification)-based RTLS (real time location system) for enhancing the performance of terminal operation system. The suggest container terminal's yard allocation for ubiquitous computing is based on current yard allocation algorism. What is difference from the existed algorism is that it shall not apply container-loading sequence to each of independent containers, but shall apply to each of group in use the RFID based RTLS. In addition, preplanning based on ubiquitous computing environment will support working of gantry cranes and yard tractors, and shorten ship turnaround time, more efficiently. It can accomplish the whole lead-time of port logistics
