Real-Time and Secure Wireless Health Monitoring

We present a framework for a wireless health monitoring system using wireless networks such as ZigBee. Vital signals are collected and processed using a 3-tiered architecture. The first stage is the mobile device carried on the body that runs a number of wired and wireless probes. This device is also designed to perform some basic processing such as the heart rate and fatal failure detection. At the second stage, further processing is performed by a local server using the raw data transmitted by the mobile device continuously. The raw data is also stored at this server. The processed data as well as the analysis results are then transmitted to the service provider center for diagnostic reviews as well as storage. The main advantages of the proposed framework are (1) the ability to detect signals wirelessly within a body sensor network (BSN), (2) low-power and reliable data transmission through ZigBee network nodes, (3) secure transmission of medical data over BSN, (4) efficient channel allocation for medical data transmission over wireless networks, and (5) optimized analysis of data using an adaptive architecture that maximizes the utility of processing and computational capacity at each platform

Determine the efficiency of program for adolescents predisposed to crime to developing positive interpersonal relationship [Suça yatk?n ergenlerde olumlu kişileraras? ilişkiler geliştirme program?n?n etkinliginin incelenmesi]

Objective: This is a semi-experimental study designed with control-experimental groups aiming to determine the efficiency of program dealing with help adolescents predisposed to crime for developing positive interpersonal relationship. The universe of the study includes 95 adolescents who were registered to the child bureau of Ödemiş County Police Center and the entire universe was decided to be included in the sample. Research was carried out with 60 adolescents who accepted the study. Methods: Adolescents were applied information form, Strength and Difficulties Questionnaire and Interpersonal Relationship Scale at first. Adolescents were divided into control and experiment groups (each groups has 30 adolescents) according to the scores they obtained from scales, age, gender, family type, school attendance status and the classes they attend. Interviews were made for adolescents in the experiment group according to their needed. Interviews that made with each of adolescent were completed in around three weeks, 180 hours. The adolescents whose interviews were finished were applied scales again. The adolescents in the control group were applied the same scales three weeks later. Findings: It was found that all of adolescents were subjected to disciplinary punishment due to fighting. 38.4% expressed that they share their problems with their mothers, 68.4% stated that their relations with their families were 'good' and %3.4 of them stated that they are misunderstood. When the determine the scores of the adolescents in Strength and Difficulties Questionnaire and Interpersonal Relationship Scale total difficulty score was found to be 13.26±4.56, nourishing interpersonal score 30.45±7.23, and poisoning interpersonal relationships score 13.06±6.34. If we consider that the cutoff point of scale, it may be said that adolescents received scores within 'normal' range. In the adolescents in the experiment group, after intervention, statistically significant decrease was found in total difficulty score and poisoning interpersonal relationships style compared to their previous scores (p0.05). No significant change was observed in the control group as no intervention was made (p>0.05).When the relation between the socio-demographic characteristics of the adolescents and their rate of benefiting from the program was investigated, it was found those girls and adolescents who share their problem with friends were benefited more from the program. Discussion: The positive means of changing in score that obtained by experiments groups adolescent shows that program was benefit. The result corrected the opinion that was enlisted to professional helping, support, and safe environment can be help them to solve their problem in spite of living problems in childhood, attaining negative behavior

The behaviour of pelvic floor muscles during uterine contractions in spontaneous and oxytocin-induced labour

PubMed ID: 29430972Term pregnant women were divided into oxytocin infusion and control groups. The electrical activities of pelvic floor muscles (PFM) were recorded at rest and during contractions electromyographically. The beginning and the end of each contraction were marked on the recorded electromyographic trace. A trace was regarded as ‘negative’ if no increase in electrical activity was observed and ‘positive’ if increased electrical activity was observed during the contractions. To evaluate the relative frequency of the areas of electrical activity during uterine contractions (UC) a ‘positive electrical activity percentage’ was used and calculated as: (total count of positive electrical activity areas)/(total count of UC) × 100. Positive and negative electrical activity percentages were compared. The percentages were significantly different between the groups (p <.01). Positive traces increased in 56.1 and 18.8% in study and control groups, respectively, (p <.01). Multiparous women showed more positive traces than nulliparous women, both in oxytocin-treated and spontaneous labour groups (p <.01). The rate of performed episiotomies was higher in the oxytocin-infused labours (p =.01). During physiological labour contractions the predominant behaviour of PFM seemed to be a relative silent status compared to a more contractile status caused by oxytocin administration. Contracted muscles may produce a counterpressure against expulsive UC leading to obstetrical injuries of these muscles and clinically higher rates in episiotomy decisions. This is the first report of behaviour of PFM during labour contractions and further prospective studies are needed to assess the role of oxytocin administration on PFM and associated clinical consequences.Impact statementWhat is already known on this subject? The physiological functions of pelvic floor muscles depend on the coordinated actions of these muscles and rely also on unique interactions between the somatic and autonomic nervous systems. Oxytocin is commonly used for the induction and augmentation of uterine contractions and such an induced labour may be more painful for the woman. What do the results of this study add? Pelvic floor muscles tend to contract more frequently during uterine contractions as labour progresses. This difference was more pronounced in labours which were treated with oxytocin infusion. What are the implications of these findings for clinical practice and/or further research? This is the first report of electrophysiological behaviour of pelvic floor muscles during labour contractions in spontaneous and oxytocin-induced labour. Oxytocin administration seems to interfere with the coordination of uterine and pelvic floor muscle contractions. This study may be of interest for researchers to investigate the effect of the worldwide liberal use of oxytocin for induction of labour on pelvic floor muscle damage during parturition. © 2018, © 2018 Informa UK Limited, trading as Taylor & Francis Group

A survey of natural radiation levels in soils and rocks from Aliaga-Foça region in Izmir, Turkey

PubMed ID: 23222553The gamma spectroscopic analysis of 226Ra, 232Th and 40K has been carried out in surface soil samples collected from Aliaga-Foça industrial region. The rock samples as parent materials of the soils are also collected and analysed for relevant radionuclides in order to evaluate the natural radiation levels. In the present study, the mean activity concentrations and ranges of the related radionuclides in the soil samples from 60 sites distributed all over the region are as follows: 226Ra is 38 (14-123) Bq kg-1; 232Th, 63 (27-132) Bq kg-1 and 40K, 633 (141-1666) Bq kg-1. Meanwhile, the ranges of natural radionuclide activities in the rock samples characterising the region are 41-95 Bq kg-1 for 226Ra, 10-122 Bq kg-1 for 232Th and 264-1470 Bq kg-1 for 40K, respectively. Based on the available data, the radiation hazard parameters associated with the surveyed soils/rocks are calculated and the results do not exceed the permissible recommended values except for soils originated from Foça rhyolites and tuffs. Furthermore, the collected data allowed for the mapping of the measured activities and corresponding gamma dose rates. © The Author 2012. Published by Oxford University Press. All rights reserved
