Real Time ECG monitoring system based on Internet of Things ( IoT )

Heart rate, body temperature and blood pressure are very critical parameters of human body. Doctors use various kinds of medical apparatus for measurement of these parameters like thermometer for checking body temperature, BP monitor for blood pressure measurement and heart rate monitor for heart rate measurement. In this paper, we have proposed ECG MONITORING SYSTEM based on IoT (Internet Of Things). This system calculates heart rate of patient and sends the value of heart rate in beats per minute (bpm) to a database on cloud. Using this system doctors at hospital can analyse the critical parameters sent by this system. Doctors can also analyse the real time health related parameters of a patients which are not admitted in hospital. This system can be integrated in ambulance wherein all the critical health related parameters of patients can be acquired and sent to the cloud. All these critical parameters can be analysed by a doctor in advance while the patient is still in ambulance. The main objective of this system is to acquire the physiological parameter using sensors and uploading these parameters to cloud. We have integrated ECG sensor in this system.
Effect of selenium supplementation for protection of salivary glands from iodine-131 radiation damage in patients with differentiated thyroid cancer.

OBJECTIVE
In the current study, we examined whether selenium supplementation during iodine-131 (131I) treatment had a radio-protective effect on salivary glands.


SUBJECTS AND METHODS
Sixteen patients with differentiated thyroid cancer were prospectively enrolled in the study. Patients after total thyroidectomy, before 131I treatment, were divided into two groups; 8 patients in the selenium group and 8 patients in the control group. Patients in the selenium group received 300νg of selenium orally for 10 days, from 3 days before to 6 days after 131I treatment. The control group received a placebo over the same period. To assess salivary gland function, salivary gland scintigraphy was performed before and 6 months after 131I treatment. Serum amylase and whole blood selenium levels were measured before and 2 days and 6 months after 131I treatment. Using salivary gland scintigraphy, maximum uptake ratio (MUR), maximum secretion percentage (MSP), and ejection fraction (EF) of each salivary gland were calculated.


RESULTS
Baseline clinical characteristics, baseline amylase and selenium levels, and parameters of baseline salivary gland scintigraphy were not significantly different between selenium and control groups (P>0.05). On a blood test performed 2 days after 131I treatment, the selenium group showed a significantly higher whole blood selenium level (P=0.008) and significantly lower serum amylase level (P=0.009) than the control group. On follow-up salivary gland scintigraphy, the control group showed significantly decreased, MUR of the bilateral parotid and left submandibular glands, MSP of the bilateral parotid and submandibular glands, and EF of the left submandibular glands (P<0.05), while the selenium group only had a significant decrease in MSP of the right submandibular gland and EF of the left submandibular gland (P<0.05).


CONCLUSION
Selenium supplementation during 131I treatment was effective to reduce salivary glands damage by 131I radiation in patients with differentiated thyroid cancer.

Reactive power control of autonomous wind-diesel hybrid power systems using ANN

This paper presents an artificial neural network (ANN) based approach to tune the parameters of the SVC reactive power controller over a wide range of typical load model parameters. The gains of PI (proportional integral) based reactive power controller are optimised for typical values of the load voltage characteristics by conventional techniques. Using the generated data, the method of multilayer feed-forward ANN with the error back-propagation training is employed. An ANN tuned static var compensator (SVC) controller has been applied to control the reactive power of variable slip/speed model of isolated wind-diesel hybrid power system. Transient responses of sample hybrid power system have also been presented.
Metformin for Obesity in Children and Adolescents: A Systematic Review

OBJECTIVE
To summarize the efficacy of metformin in reducing BMI and cardiometabolic risk in obese children and adolescents without diabetes.


RESEARCH DESIGN AND METHODS
We performed a systematic review and meta-analysis of randomized controlled trials (RCTs). Double-blind RCTs of > or =6 months duration in obese subjects age < or =19 years without diabetes were included. Our primary outcomes of interest include changes in BMI and measures of insulin sensitivity.


RESULTS
Five trials met inclusion criteria (n = 320 individuals). Compared with placebo, metformin reduced BMI by 1.42 kg/m(2) (95% CI 0.83-2.02) and homeostasis model assessment insulin of resistance (HOMA-IR) score by 2.01 (95% CI 0.75-3.26).


CONCLUSIONS
Metformin appears to be moderately efficacious in reducing BMI and insulin resistance in hyperinsulinemic obese children and adolescents in the short term. Larger, longer-term studies in different populations are needed to establish its role in the treatment of overweight children.
Project onward: an innovative e-health intervention for cancer survivors.

OBJECTIVE
This study examined the feasibility and acceptability of an Individual Internet Intervention (III) embedded and integrated into an Internet Support Group (ISG) with the ultimate goal of enhancing adherence and learning, compared with an individual internet invention alone.


METHOD
Thirty-one posttreatment cancer survivors were randomized in groups of seven to nine to either the 8-week III + ISG intervention or the 8-week III condition. Seventeen participants met the Hospital Anxiety and Depression Scale (HADS) criteria for depressive symptoms (HADS ≥ 8).


RESULTS
Among all participants, the mean number of logins over 8 weeks was 20.8 ± 17.7 logins for the III + ISG compared with 12.5 ± 12.5 in III-only (p = 0.15). Two participants in the III + ISG dropped out, compared with five in III (p = 0.39). Among the 17 participants with depressive symptoms at baseline, both the Onward and the III-only condition showed large reductions in the depression scale of HADS (d = 1.27 and 0.89, respectively). Improvement over time and time x treatment effects only reached trend significance levels (ps = 0.07 & 0.12) as this pilot was not powered to detect these differences.


CONCLUSION
Both the III + ISG and III-only demonstrated pre-post reductions in depressive symptoms and high rates of utilization compared with other web-based treatments for depression. Although it is premature to make any determination as to the efficacy of the interventions tested in this feasibility study, these results indicate that pursuing the III + ISG model, as well as standard IIIs, may be fruitful areas of future research.
A Frequency-Domain Analysis of Latch Comparator Offset due to Load Capacitor Mismatch

This brief presents a frequency-domain analysis of the latch comparator offset due to load capacitor mismatch. Although the analysis is applied to the static latch comparator, the developed method can be extended to the dynamic latch comparator.
Clinical and echocardiographic correlates of mortality in medically treated patients with severe isolated aortic stenosis and normal left ventricular ejection fraction.

BACKGROUND
Many symptomatic patients with severe aortic stenosis (AS) and preserved left ventricular ejection fraction (LVEF) are denied surgery and have a grim prognosis with medical management.


METHODS AND RESULTS
Between 2003 and 2012, among 550 patients with severe isolated AS and preserved LVEF on transthoracic echocardiography, 241 did not undergo aortic valve replacement (mean age, 83.2±7.6 years; 54% female; aortic valve area index, 0.40±0.13cm(2)/m(2); mean LVEF, 64.8±7.6%) and 67% presented with cardiac symptoms. At a mean follow-up of 25.5±25.1 months, 134 patients (56%) had died. Survival at 1, 5 and 9.5 years was 71%, 28% at 12%, respectively. Median survival was 36.3 months (95% confidence interval [CI]: 27.2-42.4 months). In unadjusted analyses, age, heart failure, hypertension, renal insufficiency, left atrial size, pulmonary artery systolic pressure (PASP), relative wall thickness and LV mass/LV end diastolic volume ratio were associated with mortality. On multivariate analysis adjusted for all significant univariate predictors, age ≥78 years, history of hypertension, left atrial diameter ≥40mm and PASP ≥42mmHg gave a joint area under the curve of 0.80 (95% CI: 0.73-0.86) for mortality.


CONCLUSIONS
In medically treated patients with severe isolated AS and preserved LVEF, older age, history of hypertension, and echo-Doppler variables reflecting LV diastolic dysfunction are independent predictors of death.
An Autobiographical Aperqu of Legal Philosophy

. In his autobiographical sketch, the author surveys sixty years of legal philosophy. He traces the major changes that have come about in the philosophy of law in the wake of the Second World War, and the gap which has been bridged between Continental and Anglo-Saxon theories. The values of liberal democracy and the acknowledgement of human rights have helped to circumvent the gulf between natural law theories and legal positivist theories.
Managing business processes through outsourcing: a strategic partnering perspective

Purpose – The purpose of this paper is to discuss business processes as building-blocks of organisational capabilities and outsourcing of business processes as a viable management approach to building strategic organisational capabilities. Design/methodology/approach – The paper develops a conceptual framework based on “strategic partnering” to successfully implement “global sourcing” of organisational capabilities and validates this framework using multiple case studies research. Findings – The paper identifies business process management, relationship management and the outsourcing value propositions as the key dimensions for business process outsourcing (BPO) success. Research limitations/implications – The paper is based on case studies of seven European clients and ten Indian service providers of BPO services. A larger survey of BPO clients and service providers may further strengthen the proposed framework and make the findings more conclusive. Practical implications – The proposed framework helps both the BPO client and the service provider organisations in understanding the critical role of relationship management in realising the intended BPO service outcomes. It also helps the BPO clients and the service providers to understand the risk and business value implications of BPO value proposition. Originality/value – The paper addresses a dearth of literature on BPO service provision and establishes the need for dyadic study of BPO services from both the client and the service provider perspective simultaneously for understanding the dynamics of this emerging service sector.
Surface plasmon enhanced silicon solar cells

Thin-film solar cells have the potential to significantly decrease the cost of photovoltaics. Light trapping is particularly critical in such thin-film crystalline silicon solar cells in order to increase light absorption and hence cell efficiency. In this article we investigate the suitability of localized surface plasmons on silver nanoparticles for enhancing the absorbance of silicon solar cells. We find that surface plasmons can increase the spectral response of thin-film cells over almost the entire solar spectrum. At wavelengths close to the band gap of Si we observe a significant enhancement of the absorption for both thin-film and wafer-based structures. We report a sevenfold enhancement for wafer-based cells at =1200 nm and up to 16-fold enhancement at =1050 nm for 1.25 m thin silicon-on-insulator SOI cells, and compare the results with a theoretical dipole-waveguide model. We also report a close to 12-fold enhancement in the electroluminescence from ultrathin SOI light-emitting diodes and investigate the effect of varying the particle size on that enhancement. © 2007 American Institute of Physics.

Breast cancer knowledge and screening practices among women in selected rural communities of Nigeria

Globally, the devastation that befalls women diagnosed of breast cancer remains inestimable. Early detection remains a major effective approach that should be employed to combat the disease. The issue of concern, however, is whether women in the rural underserved areas are aware of these early detection methods. This study was designed to assess rural women’s awareness and knowledge of breast cancer and their screening practices. The study was a descriptive cross-sectional study utilizing self developed structured questionnaire. Reliability of the instrument was determined and alpha correlation values range between 0.81 and 0.95 for the different components of the questionnaire. Data was processed using descriptive analysis and associations tested with Chi-square at 5% level of significance. The results of the findings showed that 52.7% of the women had adequate knowledge about breast cancer risk factors and symptoms. Regarding the women’s awareness about breast cancer screening methods, 52.8 and 51.7% of women have heard about Breast Self-Examination (BSE) and Clinical Breast Examination (CBE) respectively. However, few numbers of respondents (3.9%) were aware about mammography and these are people who did it for the purpose of diagnosing breast problem. Majority of the women (72.8%) did not practice BSE which is the most readily available screening method. Considering the lack of sophisticated diagnostic technology such as mammography for breast screening in the rural areas, BSE provided a unique opportunity for the women to be breast aware and to identify breast problems which may constitute danger to their health in the future. Health care professionals, most especially those at the primary health care level, should enhance the women’s skills to use this simple procedure effectively to promote their health.
Querying massive graph data: A compress and search approach

Querying graph data is a fundamental problem that witnesses an increasing interest especially for massive graph databases which come as a promising alternative to relational databases for big data modeling. In this paper, we study the problem of subgraph isomorphism search which consists to enumerate the embedding of a query graph in a data graph. The most known solutions of this NPcomplete problem are backtracking-based and result in a high computational cost when we deal with massive graph databases. We address this problem and its challenges via graph compression with modular decomposition. In our approach, subgraph isomorphism search is performed on compressed graphs without decompressing them yielding substantial reduction of the search space and consequently a significant saving in processing time as well as in storage space for the graphs. We evaluated our algorithms on nine real-word datasets. The experimental results show that our approach is efficient and scalable. © 2017 Elsevier B.V. All rights reserved.
Understanding WeChat users' liking behavior: An empirical study in China

Liking behavior in social media is growing in popularity. Yet there has been a lack of research and understanding of the factors that motivate users to click “like” in social media. In this study, based on the uses and gratifications theory, a research model is developed to examine what factors affecting users' liking behavior in WeChat. And gender is considered as the moderating factor in the model. Using 215 valid data from the WeChat users in China, the model is empirically assessed by PLS-SEM. Results show that three types of gratifications positively affect WeChat users' liking behavior: hedonic gratification (enjoyment), social gratification (social support) and utilitarian gratification (information seeking). In particular, enjoyment plays the most important role in determining the liking behavior, followed by social support and information seeking. In addition, gender acts as the moderator on the relationship between each gratification and liking behavior. © 2016 Elsevier Ltd. All rights reserved.
Investigation of Electronic Ceramic Fibers for Non-Destructive Evaluation of Advanced Composites.

Abstract : A discussion is presented on the feasibility of developing and using crystal-bearing filaments as sensors in the non-destructive evaluation of fiber-reinforced plastic structural materials. The fibers or filaments contain crystalline oxidic materials commonly referred to as electronic ceramics. Compositions investigated include ferroelectric potassium sodium niobate, lithium niobate, lead germanate, lead germanium silicate, lead zirconate titanate, and a magnetic ferrite. These electronic ceramic compositions were dissolved in compatible molten glass, shaped, annealed, and cooled to room temperature. The test shapes (filaments and disks) were then heat- treated to precipitate (exsolve) the material that had been put in solution. Progress is reported in the preparation and processing of these materials. Devitrified filaments were incorporated into test composites, with an epoxy-novalac matrix, and were subjected to preliminary electrical measurements. The effects of glass content and microstructure on electrical properties are reported. (Author, modified-PL)
The use of emotionally expressive avatars in Collaborative Virtual Environments

We argue that the use of collaborative virtual environments (CVE) which incorporate emotionally expressive avatars has the potential to engender empathy amongst users of such environments, and that the use of this technology is potentially valuable for people with autism. Empirical work in both areas is discussed. Results suggest that the introduction of emotional expressiveness enriches the subjective experience of CVE inhabitants, in particular their enjoyment and how engaging they find virtual encounters. Similarly, exploratory empirical work involving people with autism suggests they were able to understand the emotions expressed by their avatars and use them appropriately.
Effect of pre-operative neuromuscular training on functional outcome after total knee replacement: a randomized-controlled trial

BACKGROUND
Total Knee Replacement (TKR) is the standard treatment for patients with severe knee osteoarthritis (OA). Significant improvement in pain and function are seen after TKR and approximately 80% of patients are very satisfied with the outcome. Functional status prior to TKR is a major predictor of outcome after the intervention. Thus, improving functional status prior to surgery through exercise may improve after surgery outcome. However, results from several previous trials testing the concept have been inconclusive after surgery.


METHODS/DESIGN
In a randomized controlled trial (RCT) we will test the effect of a pre-operative neuromuscular training program versus an attention control program on lower extremity function - before and after surgery. We will enroll 80 participants, aged between 55-90 years, who are scheduled for TKR. In this single-blinded RCT, the intervention group will receive a minimum of 8 and a maximum of 24 training sessions plus 3 educational sessions of the knee school. The control group will receive the 3 educational sessions only. Assessments are performed immediately before and after the intervention (before surgery), at 6  weeks, 3  months and 12  months (after surgery). The primary outcome will include the Chair Stand Test as a measure of leg strength and reaction time. Secondary outcomes are knee function and pain assessed with the self-reported Knee Injury and Osteoarthritis Outcome Score (KOOS). All measurements will be carried out by a specially trained physical therapist, blinded to group allocation.


DISCUSSION
To our knowledge this is the first single-blinded RCT to test the effect of pre-operative neuromuscular training plus knee school against knee school alone--on knee function and pain, assessed immediately after the interventions prior to surgery and repeatedly after surgery.

Wide-diameter implant placement and internal sinus membrane elevation in the immediate postextraction phase: clinical and radiographic observations in 12 consecutive molar sites.

PURPOSE
To evaluate whether the combination of 5 surgical techniques in implant dentistry could be performed simultaneously in a predictable manner as effectively as each technique separately.


MATERIALS AND METHODS
Immediately postextraction, 12 wide-diameter (WD) implants were placed in maxillary first or second molar sites. The residual vertical bone height ranged between 6 and 9 mm (average 7.8 mm). An internal sinus elevation, via the osteotomy site, was carried out in 10 sites using an osteotome tool implants were then self-tapped into the osteotomy site followed by Insertion of a customized healing screw. Consequently, horizontal gaps between the bony walls and the implant neck were filled by either bovine bone mineral or tricalcium phosphate particles. Full soft tissue closure around the healing cap screw was achieved by coronal positioning of the buccal flap.


RESULTS
Soft tissue healing around the 12 implants was immaculate. In 10 sites, Internal osteotome sinus membrane elevation resulted in a height gain of between 2.5 and 6 mm (average 4.3 mm). Radiographically, bone-to-implant contact was evident. All implants were integrated and the prosthetic phase was completed after 6 months.


DISCUSSION AND CONCLUSIONS
The combination of 1-stage technique and immediate placement of WD implants, along with internal sinus floor elevation and no soft tissue reflection at the time of implantation, is an achievable task and can be performed predictably. Time, cost, and morbidity are reduced, and the prosthetic solution is also eased for the benefit of the patient.
