As Stress

This paper describes a study on evaluation of mental stress using adaptive wavelet packets filtering techniques. For mental stress to become chronic or if it remains for longer periods of time, then it can cause or trigger diseases such as hypertension, diabetes, insomnia, depression etc. There is a need for objective assessment of stress and develop counter conditions to relieve the body from stress. We have designed a wireless wearable sensor platform that can be used to capture a vast range of biomedical signals including heart rate, skin conductance and respiration rates. As stress is a reactionary phenomenon and its response vary from person to person, so an adaptive wavelet filtering packet is proposed to minimize intra subjective variations. The filtering technique has two folded effects; it reduces the classification error and it provides tuning to adapt it to users requirements. The wearable sensor platform is based on ease of use and a subject can be monitored for days and changes in his/her physiological conditions are recorded. The main advantage in monitoring stress is that if required in needs than necessary actions can be taken to remove stressful conditions.

The article is devoted to the creation of a carbohydrate product with rosehip extract in the form of sweets (glucose Fudge) with a therapeutic and preventive effect aimed at restoring the body of people exposed to intense physical and mental stress and the effects of damaging environmental factors. As carbohydrates in the recipe, simple carbohydrates (glucose) and complex carbohydrates in the form of starch molasses containing (maltose, tri - Tetra - sugars, dextrins) are used. Glucose in the formulation is the main energy ingredient, sweetener and structure-forming component that gives the product a solid consistency due to crystallization. The medicinal effect of the product is provided by rosehip extract. Numerous published studies have established its vitamin, immunostimulating and antioxidant activity, inhibition of uric acid formation and obesity, which are associated with flavonoids, other phenolic compounds, and vitamins. The list of medicinal properties of rosehip extract shows the feasibility of using it in additional nutrition of people in order to prevent diseases. For the formulation of our sweets, the extraction of crushed rosehip fruits was carried out three times with hot water at a temperature of 65-700C, followed by concentration of the extract under vacuum to 25-30% SV. The resulting extract-concentrate was introduced into the formulation in a dosage of 5.5% SV per 100 g of SV glucose Fudge, which provided the necessary dosage for the product when used from 3 (for children) to 10 sweets a day (for adults) for the prevention of colds.

Albumin Content

The blood test allows you to give an objective assessment of the state of health of animals and timely identify changes occurring in the body. To assess the content of albumins in the blood serum, the method of measuring the dynamic surface tension on the VRA-1P device, which works according to the method of maximum pressure in the bubble, was used. Based on the results of the measurements, a mathematical model was proposed, and using the regression analysis method, formulas for determining the concentration of albumins were developed, which showed good convergence with other measurement methods.

The Law

Non-contact monitoring of vital signs of a person is a reliable and safe way of promptly obtaining objective diagnostic information about the current physiological state of a patient during surgical operations, physiotherapeutic procedures or during sleep. The absence of direct contact of the sensors with the patient's body makes it possible to exclude the influence of a number of interfering factors, such as a violation or weakening of contact, which can lead to a deterioration in the quality of signals from the output of the sensors, a long-term location of the sensors on the body can have a psychological effect on the patient, changing his condition and thereby distorting the treatment method, etc. In order for the results of monitoring and diagnostics to be reliable and guaranteed accurate, it is necessary to carry out periodic metrological certification of location sensors, especially since many of them are of foreign production and their characteristics are either not standardized or do not meet the requirements of their operating conditions. Therefore, the tasks of developing methods and means for carrying out metrological tests of non-contact sensors for medical purposes are becoming urgent. Purpose – to show the possibility of implementing automated metrological tests of location sensors for medical use based on a personal computer and publicly available standard hardware and software. A method has been developed and implemented for conducting metrological tests of location sensors based on a personal computer, a digital dynamic measure of linear displacement, virtual measuring instruments, laser and ultrasonic sensors, as well as determining conversion errors in the LabVIEW environment. As an exemplary measuring instrument, it is proposed to use a webcam with a virtual device for recording the law of displacement in the LabVIEW Vison Development application. Full-scale experiments have been carried out, in which, using a digital measure of linear displacement, it is possible to reproduce with high accuracy almost any law of displacement and to regulate its informative parameters. Real movement signals were received with the help of virtual devices, recorded by two location sensors and a web camera. The errors of the means of registration are determined in comparison with the given digital method and analytically the law of movement. Introduction of the developed method and hardware and software for metrological certification of sensors of diagnostic channels of the systems of complex magnetotherapy «Multimag» and «Relaxmag». Carrying out automated metrological tests of sensors will ensure prompt, reliable and objective control of their actual characteristics, which means it will increase the effectiveness of treatment due to the prompt and continuous monitoring of the patient's functional state and an objective assessment of a number of important indicators.

The treatment of locally advanced tumors of the head and neck presents serious difficulties due to the difficulty of localizing growths, namely the proximity to vital organs and systems of the body (brain, large blood vessels) and the small size of the areas of intervention limits the choice of treatment methods. So, the development of helper methods and hardware of intraoperative visualization of blood vessels is relevant. So, the development of auxiliary methods and hardware means of intraoperative blood vessel imaging for objective assessment of adequacy of blood supply and differentiated recognition of anatomical structures is especially relevant in biomedical optics. The aim of the work is to create an experimental setup for the development, testing and modification of the algorithms for improving the quality of the image of blood vessels against the background of surrounding tissues by optical method. The article is devoted to technological and program features of developing and creating an experimental setup for intraoperative imaging. Clinical problem of the necessity of vessel imaging has been established. Current state of intraoperative vessel imaging has been analyzed. Structure of the setup has been determined. The requirements for parts of the setup have been formulated. Usage of the chlorophyll as a new liquid for blood substitution has been experimentally justified. A MATLAB-based model for quality evaluation of functions of the setup has been developed. The experimental results obtained in the article are of great practical importance for the development of a biotechnological system for intraoperative vessel imaging.

Safety ofhealth facilities (hospitals) is only partially related to the performance ofprimary structural members. Modern seismic codes provide strict requirements toboth structural and non-structural components, since the latterare alsocritical to ensure that the system remains fully operational in the case offrequent earthquakes. Thus, performance and safety checks apply also to electro-mechanicaland medical equipment,elevators, tanks, power supply systems, distributionsystems, heating, ventilation and air-conditioning systems.In the present paperattention is focusedon the analysis of the factors which make health facilities vulnerable and onthe issues related to a rational and objective assessment of performance andhealth state of structural and non-structural components. This is not a trivialtask, since functions and resilience of the system as a whole depend also onthe ability of inspectors and managers to integrate theoretical evaluationswith field measurements and their physical meaning.In this context, strategies and recommendations for a sustainableimplementation of Smart Health Facilities, which fulfilAtoE characteristics (Accuracy, Budget compliance, Computational burden,Durability, Ease of use)on a long term basis, are discussed, taking into account the specific requirementsand characteristics of the different subsystems in a hospital.
