Random k-labelsets method for human activity recognition with multi-sensor data in smart home

In today's world, we are surrounded by ambient sensors everywhere that record our data of activities of daily living. Moreover, the solutions to various applications such as health care, surveillance, home monitoring, and so on are possible by inferring this data. Thus, human activity recognition, especially in the smart home environment, has been a very actively researched problem. Multiple residents in a single home environment pose several challenges making multi-resident activity recognition a daunting task. Therefore, in this paper, we model the Random k-Labelsets method of the Multi-Label Classification to tackle this activity recognition problem. The proposed method not only takes label dependencies into account which is essential for multi-resident activity recognition but also overcomes the drawbacks of other problem transformation methods. Experiments are carried on a real smart home dataset and accuracy, precision and hamming loss are selected as metrics for evaluating the results of the proposed method

Determine the functional and radiological outcome of T3 proximal femur nail in the treatment of intertrochanteric fracture of femur

Background: T3 is the new generation nail used for fixation of intertrochanteric fractures. The lag screw is designed to transfer the load of the femoral head into the nail shaft by bridging the fracture line to allow fast and secure fracture healing. The load carrying thread design of the T3 lag screw provides large surface contact to the cancellous bone, this provides high resistance against cut out.Methods: 30 subjects attending the study were operated with T3 proximal femur nail in the treatment of intertrochanteric fracture of femur. Prospective, randomised case-controlled study done over period of 1 year.Results: Significant results were obtained while comparing the mean RUSH score and mean Harris hip score at different postoperative follow-up time intervals with good to excellent outcome and less operative time and low complications rate.Conclusions: T3 is the new generation nail used for fixation of intertrochanteric fractures and is a dependable implant for the fixation. It has good to excellent outcomes and takes less operative time with low complication rates. The anatomical shape of the nail is universal for all indications involving the treatment of intertrochanteric fractures. The load carrying thread design of the T3 lag screw provides large surface contact to the cancellous bone, thus providing high resistance against cut out. The set screw prevents rotation of the lag screw. The T3 has a single screw passing into the neck of the femur and its Set Screw that is passed into the proximal part of the femoral nail sits into the groove of the Lag screw, thus providing rotational stability

Multi-resident activity recognition using multi-label classification in ambient sensing smart homes

Activity recognition in smart home environment using wireless ambient sensing is a well-known problem that is being researched very actively. Rapid development in the sensing technologies has made human activity recognition very important for various fields such as health care, home monitoring, surveillance, etc. In this paper, we describe the use of Classifier Chain method of the Multi-Label Classification approach to tackle the task of multi-resident activity recognition. We evaluate the developed model of Classifier Chain with K-Nearest Neighbor as base classifier on real world ARAS dataset which consists of two smart homes with evaluation metrics such as accuracy, precision and hamming loss. Through results, it can be inferred that Classifier Chain method successfully caters the problem of multi-resident activity recognition taking into consideration underlying label dependencies

Binary relevance model for activity recognition in home environment using ambient sensors

One of the most important applications of the smart home environment is health monitoring and assistance by analysing activities of daily living and here Human Activity Recognition (HAR) plays a major role. The HAR problem, basically a temporal classification problem has been modelled in the past with various methods such as Bayesian Networks, Hidden Markov Model, Conditional Random Field, etc. Here, we propose the Binary Relevance Method of the multi- label classification to tackle the multi-resident activity recognition problem on real world dataset. Through the results obtained by the evaluation metrics namely accuracy, precision and hamming loss, it can be inferred that the model not only computes competitive results to previous works but also signifies the importance of the baseline Binary Relevance method to solve multi-label problems

Functional outcome of intertrochanteric fractures treated with trochanteric stabilizing plates

Background: Intertrochanteric fractures account for significant percentage of health care costs and result in high rates of morbidity and mortality. Since higher rate of mortality and complications most fractures can be successfully treated with trochanteric stabilizing plates. This study was conducted to assess functional outcome in intertrochanteric fracture femur treated with trochanteric stabilizing plates and define ideal mode of fixation for such fractures. Trochanter stabilizing plate (TSP) is modular extension of dynamic hip screw (DHS) that is mounted on lateral femoral wall to stabilize greater trochanter. It provides the flexibility to achieve plate to bone apposition as well as axial compression or angular stability because of three screw fixations at the proximal fragment. TSF can provide a stress shield for the lateral trochanteric wall and prevent lateral migration of proximal fragments. Thus, TSF does not fail at the screw bone interface and provide a strong anchor in osteoporotic bone. The multiple locking screw holes of the TSF provide various options to tackle complex fracture pattern. It functions as an internalized external fixator and minimizes the pressure on the periosteum and encourages biological healing. Methods: A total of 30 subjects of intertrochanteric fractures undergoing treatment with trochanteric stabilizing plates were taken up for the study after informed consent. Results:  Significant results were obtained using Harris hip score (HHS) at different postoperative follow up time intervals with good outcome and low complication rate. Conclusions: Trochanteric buttress plate creates biomechanically stable construct by incorporating the comminuted trochanter it restores the proximal femoral anatomy, ensuring anatomical reduction hence subsequently reduces limb length discrepancy. We thus conclude this is an effective technique and has excellent functional and radiological outcomes with minimal complication and early rehabilitation rates. As Intertrochanteric fractures of the hip is a very common condition affecting a large number of patients of variable demographics and racial background, a more widespread study is required for a more conclusive study

Advances in Electromagnetic Therapy for Wound Healing

Understanding the molecular basis of wound healing and tissue regeneration continues to remain as one of the major challenges in modern medicine. There is absolute necessity to unveil the rather elusive mechanism with a special emphasis on the approaches to accelerate wound healing. Low frequency low intensity Pulsed electromagnetic therapy is evidenced to have a significant impact on wound repair and regeneration. It provides a non-invasive reparative technique to treat an injury. In vitro studies reported a significant effect of electromagnetic field on neovascularisation and angiogenesis. There are also many pieces of evidence which support its efficiency in reducing the duration of wound healing and improving the tensile strength of scars. Here, we compared the traditional stigma associated with pulsed electromagnetic fields and weighed them with its potential therapeutic effect on wound healing. Furthermore, we emphasized the need for more focused research to determine the therapeutic strategies and optimised parameters of pulsed electromagnetic field that can assure efficient wound healing and regeneration.

Pilot application of PalmGHG, the RSPO greenhouse gas calculator for oil palm products

International audienceThe Roundtable on Sustainable Palm Oil (RSPO) is a non-profit association promoting sustainable palm oil through a voluntary certification scheme. Two successive science-based working groups on greenhouse gas (GHG) were active in RSPO from 2009 to 2011, with the aim of identifying ways of achieving meaningful and verifiable reductions of GHG emissions. One of the outputs of the second group is PalmGHG, a GHG calculator using the life cycle assessment ap-proach to quantify major sources of emissions and sequestration for individual palm oil mills and their supply base. A pilot study was carried out in 2011 with nine RSPO member companies that gave an average of 1.67 t CO2e/t crude palm oil (CPO), with a range of -0.02 to +8.32t CO2e/t CPO. Previous land use and the area of peat soil used were the main causes of the variation. Further modifications to PalmGHG continue to be made in order to make the tool more flexible and comprehensive, to refine default values, and to render it more user-friendly

Sustainable Development Goals During Covid 19: With Special Reference To Education (SDG4)

Covid-19 has come at a crucial and vulnerable stage when the multinational community is perforating into the final decade to 2030, a year specified to achieve these goals. The world has to strive hard to achieve the Sustainable Development Goals (SDGs) after the devastating effects of pandemics across the globe. Nevertheless, India has made tremendous headway in putting the “Education for All” concept into action. Several significant programmes and policies have been executed to provide free and compulsory education to all children between the age of six to fourteen years. Initiatives such as the Sarva Siksha Abhiyan (SSA) and the Right to Education (RTE) have provided much-needed support to India's education system. Education is becoming more accessible, equitable, and high-quality. However, current accomplishments and regardless of efforts, there are multiple gaps existing in the country's educational system. The paper's objective is on India's current efforts to contextualising Goal 4 of the Sustainable Development Goals (SDGs) on education in the pre and post pandemic Indian scenario by incorporating them into the creation of New Education Policy. The paper also includes the required course of action which can be adopted to achieve the target within the defined time limits. It also looks at changes in education attainment at all levels in India, as well as some of the significant difficulties in the education system, such as quality education and accessibility.
