RESUMO

Energy harvesting from the ambient wireless electromagnetic energy has grown recently in the field of self-sustained and autonomous sensor networks. This technique needs to design a dedicated antenna to receive ambient power within the corresponding frequency band, which increases the designing difficulty and complexity of the system in most degrees. Besides, the available power in the low-frequency bands near 100 MHz is a good power source for energy harvesting. But there is less energy harvesting investigation focused on this frequency band due to the requirement of large size antenna. In this paper, we analyze the feasibility of using the human body as a monopole antenna for energy harvesting in the frequency range of 20-120 MHz. A simulation platform based on HFSS software is built to optimize the performance of the human body antenna. Based on the optimum design of human body antenna, actual measurements in a general electromagnetic environment are carried out to measure the received power. The results showed that there are about -51dBm power and -48.67dBm power can be received at a frequency of 57.72 MHz and frequency band of 20 MHz-120 MHz respectively.

RESUMO

In this study, we present a human body shape statistical model including elderly people, which is constructed using principal component analysis (PCA) on 3D body scan data of approximately 130 people. As a pre-process step, a template human body mesh model is fitted to 3D scan data using a coarse-to-fine surface registration technique based on a conformal deformation method, in order to establish correspondences between the scans of different subjects possibly in different poses. To change body style by a small set of parameters, such as "age", "weight" and "height" or the easily measurable anthropometric parameters like "shoulder width", the linear transformations between these attributes and the first 10 principal component scores are obtained. We design a simple user interface to use this deformation model to generate different body styles easily. As a result, we were able to produce and show body styles capturing the characteristics of elderly people whose shoulders fell and back bent. Finally, as an application, we used our deformation method to generate different body types, performed forward dynamics simulations in an assistive device setting and visualized the differences in contact pressure distributions due to body shape changes.

RESUMO

Abstract: Objective To discuss the effects of polybrominated diphenyl ethers (PBDEs) exposure in e-waste dismantling region on the human body and provide data support for the identification of environmental health damage to residents in the e-waste dismantling region. Methods Adults in an e-waste dismantling region (exposed group, 54 participants) and a control region (control group, 58 participants) were selected, questionnaires were carried out and blood and urine samples were collected. Blood PBDEs, blood lipids, blood routine, blood lead, urine cadmium, urine chromium and urine nickel were detected. T-test was utilized to compare the differences of PBDEs between the two groups. Multivariate analysis were utilized to compare the differences between the two groups in blood routine indexes. Linear regression was used to analyze the relationship between PBDEs and blood routine. Results Exposure levels of PBDEs were significantly higher in the exposed group (240.00 ng/g, adjusted mass fraction of blood lipids, thereafter) than in the control group (93.00 ng/g, P<0.05). There was no statistical significance in the differences in most blood routine indexes of the two groups ( P>0.05), and their reference values were all within normal ranges. Mean platelet volume, plateletcrit, basophils percentage, absolute value of basophils, and mean corpuscular hemoglobin concentration were higher in the exposed group than in the control group (P<0.05). Platelet distribution widths were lower in the exposed group than in the control group and below the normal reference range (P<0.05). Conclusion PBDEs exposure in e-waste dismantling region tend to change platelet morphology, the number of basophils, and mean corpuscular hemoglobin concentration, and may pose potential health hazards to local residents.

RESUMO

The body at the intersection of the natural, social and private. Confronted with a sick body, a body which no longer enjoys the "silence of the organs" within it, an ageing, tired body, caregivers, aside from the care they provide, are faced with a symbolic dimension. At the crossroads between the private and the social spheres, in a confrontation which connects them to an ancestral practice, that of the body as a tool of perception, both "touching and touched", a site of "incorporated" consciousness, caregivers also question their relationship with their own body.

RESUMO

Nursing clinical approach, listening to the body. In their practice working closely with patients and their families, nurses base their clinical approach on the gathering and analysis of the multiple signals sent by the body of the patient they are caring for. In collaboration with the doctor, the monitoring of vital signs and biological data helps to guide the care and the choice and implementation of therapies. A concrete case illustrates the contribution of nursing sciences to the clinical approach led by the nurse.

RESUMO

Supporting the professionalisation of student nurses through the approach of the body. When student nurses begin their training, their approach to others' bodies is shaped by social norms. This relationship changes through their studies and their practice placements, until they become qualified professionals. Becoming a caregiver requires them to change their relationship with the body. How does the training support students in the transformations of their representations, enabling them to be competent in the nurse-patient relationship within the other person's private sphere?

RESUMO

Body and culture, nursing approach in home care. Working extremely closely with patients' bodies when they provide care in the home, nurses interact with households' private spheres. The intercultural dimension of their competencies enables them to approach the references and beliefs of their patients and to create with them the conditions favourable to the provision of care and relief for their unhealthy bodies.

RESUMO

Body care and development of the premature infant. The observation of newborns' reactions to different stimulations enables their behaviour to be interpreted and the support provided to be adjusted. Developmental care such as swaddling, tucked posture and skin-to-skin contact favours the harmonious development of premature infants and encourages the parents to become involved in their care as early as possible.

RESUMO

The body at the boundaries of care and ethics. The body is the site of a variety of explorations, from the most basic to the most sophisticated imaging examinations, to provide a diagnosis, monitor the evolution of a pathology or decide on a therapy. For the patient, the examination is an ordeal, as is the wait for the results. In their role in providing images for clinicians, medical imaging professionals must ensure that they adopt an ethical approach showing compassion towards the person whose body is undergoing investigation.

RESUMO

Consciousness and the body. Life is expressed in the body through physical, chemical and biological processes as well as through the emergence of immaterial dimensions such as consciousness and subjectivity. These material and immaterial dimensions, connected and interdependent, form the basis of our humanity and should be considered together in the case of a global and personalised approach to the care practice.

RESUMO

Human body movements can convey a variety of emotions and even create advantages in some special life situations. However, how emotion is encoded in body movements has remained unclear. One reason is that there is a lack of public human body kinematic dataset regarding the expressing of various emotions. Therefore, we aimed to produce a comprehensive dataset to assist in recognizing cues from all parts of the body that indicate six basic emotions (happiness, sadness, anger, fear, disgust, surprise) and neutral expression. The present dataset was created using a portable wireless motion capture system. Twenty-two semi-professional actors (half male) completed performances according to the standardized guidance and preferred daily events. A total of 1402 recordings at 125 Hz were collected, consisting of the position and rotation data of 72 anatomical nodes. To our knowledge, this is now the largest emotional kinematic dataset of the human body. We hope this dataset will contribute to multiple fields of research and practice, including social neuroscience, psychiatry, computer vision, and biometric and information forensics.

RESUMO

The purpose of the work is to study the possibilities and options for assessing the degree of bilateral symmetry of dermatoglyphic signs of the right and left palms in solving the practical task of forensic medicine in establishing the belonging of body parts to one or different persons. The material of study was fingerprints of 600 palms of 300 people. It was found that the dermatoglyphic signs of the palms are characterized by a high degree of bilateral symmetry. The most consistent with each other on the right and left palms are the rudiments of papillary ridges, ridge counting and the distance between the finger triradiuses. In practical terms, the most informative are the coincidence of values of the characters having an average frequency of occurrence; coincidence of frequent signs have reliable, but low diagnostic significance. It is shown that, using the recommended set of dermatoglyphic signs of the palms, a forensic expert can, with a high degree of certainty, solve the question of whether the parts of body with the palms belong to one or different dead persons. The prospects of further research aimed at improving the technique are considered.

RESUMO

Proprioception acquires a crucial role in estimating the configuration of our body segments in space when visual information is not available. Proprioceptive accuracy is assessed by asking participants to match the perceived position of an unseen body landmark through reaching movements. This task was also adopted to study the perceived hand structure by computing the relative distances between averaged proprioceptive judgments (hand Localization Task). However, the pattern of proprioceptive errors leading to the misperceived hand structure is unexplored. Here, we aimed to characterize this pattern across different hand landmarks, having different anatomo-physiological properties and cortical representations. Furthermore, we sought to describe the error consistency and its stability over time. To this purpose, we analyzed the proprioceptive errors of 43 healthy participants during the hand Localization Task. We found larger but more consistent errors for the fingertips compared to the knuckles, possibly due to poorer proprioceptive signal, compensated by other sources of spatial information. Furthermore, we found a shift (overlap effect) and a temporal drift of the hand perceived position towards the shoulder of origin, which was consistent within and between subjects. The overlap effect had a greater influence on lateral compared to medial landmarks, leading to the hand width overestimation. Our results are compatible with domain-general and body-specific spatial biases affecting the proprioceptive localization of the hand landmarks, thus the apparent hand structure misperception.

RESUMO

O estudo da Anatomia Humana (AH) é parte integrante e de relevância inquestionável na graduação dos cursos da saúde. Com a constante redução na carga horária destinada à AH e diante dos debates sobre os novos métodos de ensino, o uso do código de quick response (código QR) se mostrou promissor. Nesse sentido, foi desenvolvido no Departamento de Anatomia da Universidade Estadual de Londrina (UEL) o processo de catalogação das estruturas anatômicas com o uso do código QR, sendo nosso objetivo relatar esta experiência. Neste processo, as estruturas dissecadas no Laboratório de Anatomia da UEL foram catalogadas com base em uma planilha contendo a correlação entre estruturas e números e, as informações de cada estrutura transcritas em um código QR através de um gerador eletrônico, sendo então impresso, plastificado e anexado à peça anatômica. As marcações foram realizadas por meio da sutura de etiquetas enumeradas. Dentro da discussão dos métodos alternativos de ensino há como exemplos a plastinação, a projeção em três dimensões e a prospecção. Em destaque neste relato, o uso do código QR mostrou-se como uma alternativa válida na agregação de conhecimento nos currículos acadêmicos. Por meio das atividades empreendidas no processo de catalogação, foi possível, além da aquisição de mais tempo dedicado ao conhecimento teórico-prático em AH, ampliar a independência no estudo e no desenvolvimento de pesquisas. Dessa forma, tem-se a oportunidade de se expandir as análises voltadas ao ensino da AH e aos novos métodos de aprendizado.


The study of human anatomy is a relevant part of the curriculum of health course graduation students. Given the constant reduction of hours destinated to the study of Anatomy and the debates regarding new teaching methods, the use of the Quick Response Code (QR code) has shown to be promising. Therefore, the Anatomy Department at the State University of Londrina (UEL) has developed a cataloging process concerning anatomical structures with the application of QR code, and this paper has the purpose of reporting on such experience. In the process, the structures dissected in UEL's Anatomy Laboratory were cataloged based on a spreadsheet which contained the correlation between these structures and numbers; the information regarding each structure was then transcribed into a QR code using a digital generator, with posterior printing, lamination and attachment to the body part. The labels were made by sewing the numbered tags onto the structures. Within the discussion regarding alternative teaching methods, examples can be given regarding lamination, three-dimension projection and prospection. The use of the QR code has proven to be a valid alternative in aggregating knowledge to academic curriculum. Through the activities performed in the process of cataloging, it was possible not only to dedicate more time to the theorical and practical learning of human anatomy, but also to increase the independence in studying and developing research. Furthermore, there is an opportunity to expand the analysis directed toward human anatomy teaching and toward new learning methods.

RESUMO

BACKGROUND: Changes to human body composition reflect changes in health status to some extent. It has been recognized that these changes occur earlier than diseases. This means that a reasonable prediction of body composition helps to improve model users' health. To overcome the low accuracy and poor adaptability of existing human body composition prediction models and obtain higher efficiency, we proposed a novel method for predicting human body composition which uses a modified adaptive genetic algorithm (MAGA). METHODS: Firstly, since there are many parameters for a human body composition model, and these parameters are associated, we designed a new parameter selection approach by combining the improved RReliefF method with the mRMR method. Following this, selected parameters were used to establish a model that fits body composition. Secondly, in order to accurately calculate the weight of parameters in this model, we proposed a solution which used a modified adaptive genetic algorithm, taking advantage of both roulette and optimum reservation strategies. This solution also has an improved selection operator. Thirdly, taking the percentage of body fat (PBF) as an example of body composition, we conducted experiments to compare performance between our algorithm and other algorithms. RESULTS: Through our simulations, we demonstrated that the adaptability of the proposed model is 0.9921, the mean relative error is 0.05%, the mean square error is 1.3 and the correlation coefficient is 0.982. When compared with the indexes of other models, our model has the highest adaptability and the smallest error. Additionally, the suggested model, which has a training time of 28.58s and a running time of 2.84s, is faster than some models. CONCLUSION: The PBF prediction model established by MAGA has high accuracy, stronger generalization ability and higher efficiency, which could provide a new method for human composition prediction.
