The rapid advancements in Information and Communications Technologies (ICTs) and the increasing number of smart things (portable devices and sensors) enable the transfer of health resources and healthcare by electronic means. This is known as ehealth, and today is closely related to the Internet, which provides a new medium for dissemination of healthcare-related information and for interaction and collaboration among institutions, health professionals, health providers and the public. Increased efficiency in healthcare, improved quality of care, availability, responsibility and satisfaction of patients and consumers are the main benefits ehealth offers. Unfortunately, there are many challenges associated with e-health adoption, especially in developing countries like Bosnia and Herzegovina. To understand and address the challenges of implementing and adopting e-health in Bosnia and Herzegovina, this paper presents a review which identifies the main political, economic and technological challenges for widespread e-health adoption. © Springer Nature Singapore Pte Ltd. 2017.

Nowadays the technical solutions related to energy resource management are being rapidly developed and integrated into the daily lives of people. The energy resource management systems use sensor networks for receiving and processing information during the realia time. Despite the large number of research related to increasing the life expectancy of a network, node positioning, network clustering as well as the optimization of the data-processing model, issues related to the data flow management and classification of the information become more and more topical; they allow to reduce the amount of transmitted information within the network. The network load of the unstructured information flow is the most important aspect that impacts the service quality of the network as well as the life expectancy of a node; as a result, the methods of network performance optimization and increase in life expectancy in the networks with a high information transmission rate become ineffective. Nowadays the amount of transmitted information in the Internet of Things networks is increased and becomes chaotic which results in the reduction of the overall network efficiency and life expectancy. The article discusses the management method of the network data flow that can respond to a data flow programming task whilst taking into account the balancing of the node energy in the network. © 2017 The Authors.

Mono-electrode self "zeroing" air-ion counter and mobility (size) scanning spectrometer (CDI-011) based on the Gerdien aspirated condenser principle has been developed. Instrument is intended for short- and long-term indoor and outdoor air-ion concentration measurements and scanning of air-ions by mobility. Measuring small currents (typically 10 -14 A) generated by the air-ions in outdoor conditions is demanding and causes many problems related to change of temperature, relative humidity, wind and electromagnetic noise. Also, measuring of both ion polarities with mono electrode detector require alternate changes of the polarizing voltage sign which produces capacitive current spikes. Various techniques, including "zeroing" method, have been applied to successfully overcome most of these measuring interferences. © 2011 Elsevier B.V. All rights reserved.

Robust and Axiomatic design, a property-based approach in design, is applied and integrated into a new methodology for developing Functional Requirements (FR) or Design Parameters (DP). The reliability of the design structure and the elementary reliability of the design components are used as a functional requirement of the automotive gearbox, in relation to the service life and operation conditions, and also as a design constraint in analytical relationships. For this purpose, elementary reliability and allowable stress are defined in a specific way. The automotive gearbox, operating under varying and random operation conditions, is used as a case study. The same design structure has to operate under different operation conditions. In these circumstances, the carrying capacity as a functional requirement is related to the operation conditions and operation regime. The model presented in this paper, as well as a computer program, enable identification of this carrying capacity. This paper discusses an interdisciplinary and multi-methodological integrated approach to the presented task. Experimental data regarding the failure probability of gearbox components and the probability of operation conditions processing, the decomposition of gearbox structure, and the elementary reliability treatment as a component of design property are only some of the methods applied. © 2013 Journal of Mechanical Engineering.

MAST4HEALTH is set on the concept of a multidisciplinary approach to assess a non-pharmacological intervention for managing NAFLD/NASH, one of the most common complications of obesity and diabetes mellitus in Western populations affecting approximately 50% of diabetics and 76% of obese patients. Because of limitations in current NAFLD treatment therapies, many new efforts focus on exploring non-pharmacologic means for managing the disease and in particular through dietary substances or bioactive phytochemicals in fruits, vegetables, and plants or their products. MAST4HEALTH aims at exploring the effect of Mastiha, a natural product of Greece which was recently shown to possess antioxidant/anti-inflammatory and lipid lowering properties. We designed a multicenter randomized double blind placebo controlled (parallel arm) clinical trial to test the effectiveness of Mastiha supplement as new non-pharmacologic strategy for NAFLD/NASH treatment. MAST4HEALTH will explore gene-diet interactions, more specifically the potential personalized activity of the Mastiha, and correlate genetic and epigenetic markers with metabolomic and intestinal microbiota profiles pre- and post-intervention. The effectiveness of the proposed intervention will be evaluated via clinical and laboratory markers of the disease. To this end, MAST4HEALTH will train a number of researchers and PhD students in multidisciplinary approaches of this survey. MAST4HEALTH is expected to build and enhance cooperation among partners meanwhile strengthening the interaction between our academic and non-academic sectors

The photorefractive effect presents a periodical change of the refractive index of an optical environment under the influence of a coherent light. An interesting phenomenon which occurs at this effect is optical phase conjugation (PC). Photorefractive oscillators, that is photorefractive mirrors present important decides in photorefractive optics and their function is based on photorefractive effect. In these oscillators, a phase-conjugated light beam occurs. The basic characteristics of photorefractive oscillators, such as reflectivity, the existance of the oscillation threshold and the threshold of the coupling strength are explained by the so-called grating-action method. This is analysed on a ring oscillator, semilinear mirror and linear mirror.

In this paper, emphasis is placed on the complexity of rural-urban relations and their reflection on the important socio-geographical processes, from de-agrarian and migration to the creation of new settlements and strengthening nodality individual centres. A clear polarization in urban and rural areas is more difficult due to the lack of adequate statistical indicators or deployment of institutions with different degree of importance, population density and distance from major city, providing sufficiently clear evidence of the degree of urbanity of local communities. This can be best seen in the Bosnia and Herzegovina (BiH) which is sparsely populated country with an average of 74 inhabitants/km2. Since there is a clear correlation between this indicator and sustainable development, increasing urbanization rates, which can stimulate economic growth and reduce poverty, is set as the primary social objective. Many developing countries looking for a way better governance of rural-urban relations, as one of the elements of inclusive growth, as a crucial element in the development of any society through innovation (industry) and harmonious territorial relations (urban-rural). Since BiH has a negative historical heritage but also unfavourable indicators of the degree of urbanization (40%), macroeconomic stability (29% of the GDP of the EU average) and the degree of innovation (44% compared to Switzerland) it is clear that should be analyzed and rural-urban relations as one of the signposts along the way of creating a better and healthier society. © 2016 Goran Mutabdzija, published by De Gruyter Open.

To determine the validity and psychobiological significance of salivary cortisol as a biomarker of stress in the experiments. Stress is defined as a state in which homeostasis is jeopardized by the action of various external and internal stressors. The effect of cortisol is made through specific receptors located in the cytoplasm of the target cells. Determining blood cortisol levels, which has been the most widely used method, is characterized by certain shortcomings. The process of taking blood samples from the vein is accompanied by additional stress, which results in falsely positive results. Another flaw is found in the fact that cortisol taken and measured from serum or plasma represents total cortisol, not the free, biologically active one. Cortisol response lags behind ACTH by 5-20 minutes, with peak blood levels achieved in 10-30 min. The transfer of cortisol from blood to saliva takes place rather quickly, within no more than 2-3 min. Although, the studies on correlation between saliva cortisol concentrations and free levels of this hormone in blood samples are lacking, salivary cortisol offer a novel approach in research of stress biomarkers with its ease of collection and potentially wide scope for application.

In this paper, thermal buckling of double-layered graphene sheets (GSs) with various boundary conditions is analyzed. The new first-order shear deformation theory (NFSDT) is reformulated using nonlocal differential constitutive relations of Eringen. Unlike the conventional first-order shear deformation (FSDT), NFSDT contains only two unknowns. It is assumed that two GSs are bonded by an internal elastic medium and surrounded by external elastic foundations. The equations of equilibrium of the nonlocal model have been derived by using the virtual displacement method. Analytical solutions for the thermal buckling of double-layered GSs under various boundary conditions are presented. The analytical expression is given for the three types of temperature distribution as uniform, linear, and nonlinear temperatures rise through the thickness of the plate. Two comparison studies are carried out to demonstrate the high accuracy of the presented nonlocal NFSDT. The influences of nonlocal parameter, plate aspect ratio, elastic foundation parameters, boundary conditions on critical buckling temperature, and critical temperature ratio are investigated. © 2016 Elsevier Ltd.
