Authors: Trusov P.V. , Zaitseva N.V. , Chigvintsev V.M. , Lanin D.V.
Published: November 2018

To know the processes occurring in the neuroendocrine and immune system, the complex and branching regulation mechanisms should be taken into account. Most of the studies in this area are dedicated to the biological and mathematical description of individual parts of the regulatory mechanisms, and it greatly facilitates the understanding of the phenomena being studied. But there is a lack of comprehensive description of the processes and internal communications. In the present article, a mathematical model for describing the antiviral immune response is considered taking into account the interacting regulatory influences of the immune and neuroendocrine systems. To describe the innate immunity, the proposed model uses parameters reflecting quantitative measures of the interferon concentration (the inductor of resistance to the infection of target organ cells) and NK-cells (responsible for removing of the infected cells). The simulation of acquired immunity is performed using parameters characterizing the concentration of virus-specific cytotoxic T cells and antibody-forming B lymphocytes. The regulatory mechanisms considered in the model cover the influence of the hypothalamic-pituitary-adrenal axis and the populations of the T-helper cells. The model is developed within the framework of the concept of a multi-level model of the human body, taking into account the interactions between systems and the functional state of the organs included in the review. The model also takes into account the spatial organization of immune and infectious processes in various organs and tissues, for which the delay time of interaction of the components is introduced. The model includes a system of 18 ordinary differential equations with a delayed argument, the parameters of which characterize the rates of various processes that affect the dynamics of infection. The parameters are identified according to published experimental data describing the process of infection of the body with a virus. The dynamics of the immune and neuroendocrine systems under viral infection was calculated, taking into account the disturbance of the synthetic function of the bone marrow. The study provides a qualitative picture of the biological factors that can explain the kinetics of the development of a viral infection.
Felosztás vagy felemelkedés? Ukrajna, Európa „nagy tortája”
Authors: Karácsonyi Dávid
Published: November 2018

A sokáig saját permanens társadalmi-gazdasági válságával foglalkozó Ukrajna 2014 után szinte egyik percről a másikra került a világpolitika centrumába, aminek oka a konfliktus mögötti sokkal szélesebb geopolitikai dimenzió, illetve az orosz–nyugati viszony kiéleződése volt.

Ukrajna hatalmas területe, természeti erőforrásai (termőföld és ásványkincsek) és népessége ellenére sem tudott szert tenni középhatalmi státuszra, ami nem csak belső okokkal magyarázható. Ukrajna valójában Európa utolsó nagy tartalékterülete, amelyről nem dőlt el még, hogy hosszabb távon az EU vagy az Oroszország dominálta tér részét képezi-e.

E regionális földrajzi szempontú írás arra kísérel meg választ adni, hogy szomszédsága miként tekint Ukrajnára: mint emberi és természeti erőforrás-tartalékterületre vagy mint pufferzónára Oroszország és a Nyugat között. Van-e esélye Ukrajnának hosszabb távon az adott feltételek mellett politikailag, gazdaságilag stabil országgá válni?

Az ország fejlődése mindig is a szomszédságától függött. Az ukránság csak akkor tudott önálló szereplő lenni, amikor a nagyhatalmi erőviszonyok kiegyenlítettek voltak. Ilyen időszak a posztszovjet éra is 1991 és 2014 között, amely éppen Ukrajnában zárult le.

Ukrajna a függetlenné válás óta szomszédjaihoz képest is mélyebb demográfiai válságba került. Ukrajna népessége rendkívül gyorsan elöregszik, amit csak súlyosbít, hogy szomszédjai elszívják a munkaerőt. Főként a visegrádi országok próbálják innen pótolni hiányzó munkaerejüket.

Miközben a földpiaci moratórium miatt egyelőre csak korlátozott versengés folyik nemzetközi téren is a termőföldekért, amelyek a világon a legértékesebbek agrárpotenciáljukat tekintve, a kelet-ukrajnai nehézipart súlyosan érinti a politikai válság.

Az „ukrán kérdés” megoldása valójában az orosz–nyugati viszony függvénye. A Nyugat és Oroszország közötti távolodás Ukrajna jövője szempontjából igen kedvezőtlen forgatókönyv.

Directivity of Self-Fulfillment and Personal Realization of Teenager
Authors: Golovanova N.F. , Dermanova I.B.
Published: November 2018

The authors ground the necessity to clarify the terminological and phenomenological specifics of the terms: “self-fulfillment”, “personal development”, “self-development”. The attention is drawn to the formal usage of these terms in the pedagogical science and the ambiguous interpretations by different scientific schools of psychology. The research of the manifestation of self-fulfillment and personal development is performed based on a selection of 126 teenagers, engaging the “Personal growth” scales from the methods of psychological well-being by C. Ryff, the “Personal growth” scales from the methods of “Life aspirations” by E.Deci, R.Ryan, as well as the author’s method of directivity to self-fulfillment and method to reveal the significance by V.Y, Kotlyakov. For the first time the authors’ questionnaire to measure the self-development in different life spheres is employed. The analysis of the empirical results allows to make a grounded statement that the contemporary teenagers have a prevailing egocentric directivity of self-fulfillment and reveals as well the importance of the interest to the moral aspects of being and the interiorized values of personal growth for the harmonious self-fulfillment of the teenager.
The Problem of Personal Self-Determination in L. I. Bozhovich’s Works and its Development from the Viewpoint of the Subject-Centered Approach
Authors: Ermolaeva M.V. , Lubovsky D. , Silaeva L.V.
Published: November 2018

The article analyzes the understanding of self-determination in L. I. Bozhovich’s works, authors present the theoretical context in which self-determination was considered in her researches (development of personality as the mastering of the behavior, self-determination as a free choice). It is shown that three approaches to the study of self-determination in Russian psychology were created on the basis of L.I. Bozhovich’s approach to the study of self-determination: self-determination as self-comprehension, as an orientation in the system of social values and as the development of subjectivity. It is shown that L. I. Bozhovich’s approach to the study of subjectivity is closest to the subject-centered approach in contemporary Russian psychology. The stages of personality development, outlined in L.I. Bozhovich’s works are considered as the stages of subjectivity formation. Authors are planning to create educational practices for adolescents based on their typical activities and aimed to the development of personal reflection as a basis of self-cognition and self-determination.
Nonvalvular atrial fibrillation: a study of epidemiology, demography and clinicoetiological profile in Central India
Authors: Jain Mayank , Kiyawat Priyanka
Published: November 2018

Background: Atrial fibrillation (AF) is the most common sustained disorder of cardiac rhythm. To study the epidemiology, demography and clinicoetiological profile of nonvalvular atrial fibrillation, such studies are sparse in India.Methods: One hundred sixty-five patients of nonvalvular atrial fibrillation were enrolled prospectively in the study during the period February 2017 to May 2018. Patients with an electrocardiographic documentation of atrial fibrillation, either chronic or paroxysmal were enrolled in the study. Patients underwent thorough physical examination, routine laboratory testing, and other relevant investigations to assess the underlying etiology. Baseline characteristics of all the patients’ viz. type of AF, primary etiological diagnosis, and baseline clinical parameters were noted. Statistical analysis was done using percentage analysis.Results: A total of 165 patients were enrolled in the study. The vast majority of patients were elderly; with the majority being in the 56-65years age group (45.45%). AF was more common in men (56.3%). Systemic hypertension was the most common etiological association (80%).Conclusions: Present study found that advanced age and male gender are significant risk factors for AF. Systemic hypertension is the most common etiological association with nonvalvular AF.
Alterations of liver enzymes in T2DM: a case control study
Authors: G. S. Chandrashekhar
Published: November 2018

Background: Liver plays an important role in regulation of blood glucose in fed state as well as in fasting. Diabetes mellitus can result as a consequence of liver disorder and vice versa. Objective of the present study is to compare the liver enzymes in type 2 diabetic patients as compared to non-diabetic patients.Methods: A case- control study was conducted in Clinical Biochemistry Laboratory, Adarsha Super speciality Hospital, Udupi from April 2018 to August 2018. The data of 174 diabetic patients and 118 healthy people as controls was collected. Fasting blood glucose, aspartate aminotransferase (AST), alanine amino transferase (ALT) and alkaline phosphatase (ALP) were estimated in the study subjects.Results: It was found that AST levels (47.55±4.69U/L) in diabetics extremely significantly high as compared to controls (33.51±2.33U/L). ALT levels were insignificantly high in diabetics compared to controls. ALP was significantly elevated (p=0.0002) in diabetics. Correlation study showed a weak positive correlation between AST, ALT and blood glucose. Odds ratio showed a higher risk of liver enzyme elevation in diabetics. Risk of elevation of AST was found to be 1.65 times high and ALT was 1.25 times high in diabetics compared to non-diabetics.Conclusions: Diabetics had high liver enzymes as compared to non-diabetics. An association was found between type 2 diabetes mellitus and liver enzymes. For better characterization of cause and effect, further studies need to be done on alterations in liver function tests along with the histopathological analysis of liver biopsy samples.
Community Engagement, Child Welfare, and Domestic Violence Service Agencies
Authors: MacPherson Colleen
Published: November 2018

Although coordinated community responses to domestic violence are widely encouraged in the literature as a best practice approach, collaboration between multiple domestic violence response service agencies and government systems is often not achieved. Because of the fragmentation of domestic violence services, this literature review examines community engagement in general and the need for coordination between child welfare agencies and women serving anti-violence services in particular. The skills and strategies necessary for community engagement are explored along with the historical relationship between the two service streams. Also included is a review of the barriers to collaboration between child welfare and women serving agencies along with recommendations to overcome these hurdles. By way of summation, a discussion is provided on how information learned through this review process may be applied to practice for Child and Youth Care Practitioners and others who take up the difficult task of responding to the complex needs of families experiencing domestic violence.
Cost and Time Management Efficiency Assessment for Large Road Projects Using Data Envelopment Analysis
Authors: AHBAB Changiz , DANESHVAR Sahand , CELIK Tahir
Published: November 2018

Upon the completion of national road projects, their
cost and time deviations are often reported. These deviations from the
projected values are a result of complications in the time and cost management
of such projects. Controlling the cost and time overrun of projects is
important for successful implementation and efficient project management.
However, few studies have attempted to measure the project cost and time
management efficiency in civil engineering. Thus, this issue requires further
investigation. In this study, large road projects that had poor cost and time
management were selected. The chosen projects were configured as Decision
Making Units (DMUs) in a Data Envelopment Analysis (DEA). DEA is a
non-parametric modern mathematical tool for measuring relative managerial
performance and determining efficient DMUs. A list containing the causes of
cost and time deviations and the percentage deviation for each DMU was
prepared. The cost and time management efficiency of the DMUs was calculated
using DEA, and the resulting values were ordered according to importance. It is
believed that this process will contribute to better cost and time management.
STAT3 is involved in IL-6-Mediated Downregulation of Hepatic Transporters in Mice
Authors: Abualsunun Walaa Ali , Piquette-Miller Micheline
Published: November 2018

Interleukin (IL)-6 decreases hepatic expression of numerous transporters. Although IL-6 signaling occurs through STAT3, the extent of the involvement of the STAT3 signaling pathway has not been elucidated. PURPOSE: Our objective was to investigate whether IL-6-mediated effects occur through STAT3, and whether PXR plays a role in this regulation. METHOD: PXR null (-/-) or wild-type (+/+) male mice were pre-dosed with a selective STAT3 inhibitor S3I-201 (7.5 mg/kg ip) or vehicle (n=5-8/group) 30 minutes before receiving a single dose of IL-6 (1 µg ip) or saline. Animals were sacrificed after 6 hours and liver samples were analyzed using qRT-PCR and western blotting. RESULTS: As compared to saline controls, IL-6 decreased the expression of Cyp3a, Abcb1a, Abcc3, and Slco1a4 20-70% similarly in PXR (+/+) and (-/-) mice at 6 hr, while downregulation of Abcb11, Abcc2, Slc10a1and Slco2b1 was only seen in PXR (+/+). Pre-administration of S3I-201 attenuated IL-6-mediated changes of most transporters in PXR (+/+) and PXR (-/-) mice. At early times after IL-6 administration (10-120 minutes), transcript levels of Socs3, PXR, Abcb1a, Abcc3, Abcb11, Slco1a4 and Slco2b1were increased in PXR (+/+) mice. CONCLUSIONS: Our findings demonstrate that IL-6 imposes a significant downregulation of numerous ABC and SLC transporters in liver primarily through activation of the STAT3 signaling pathway. Based on time-dependent changes in transporter expression, downregulation likely occurs downstream of STAT3 activation.  As IL-6 is elevated in many diseases, understanding the underlying mechanism(s) involved in transporter dysregulation will allow us to predict potential drug-disease interactions.
El constitucionalismo radical ambiental y la diversidad cultural en América Latina. Los derechos de la naturaleza y el buen vivir en Ecuador y Bolivia
Authors: Bonilla Maldonado Daniel
Published: November 2018

Las constituciones multiculturales y ambientales de Ecuador y Bolivia se estructuran alrededor de los siguientes tres elementos: los principios de plurinacionalidad e interculturalidad; los derechos de la naturaleza; y el principio del buen vivir. Estos tres elementos se articulan de manera innovadora y se vinculan de forma creativa en estas dos cartas políticas. Ninguna otra constitución moderna ha incluido y conectado este conjunto de principios y derechos; ninguna ha dado tanta importancia a las epistemologías de los comunidades indígenas. Estos derechos y principios constituyen una contribución imaginativa al debate global sobre la diversidad cultural, los derechos humanos y el medio ambiente. Este conjunto de normas, además, cuestionan la economía política dominante del conocimiento legal que a priori considera al Sur Global como un contexto pobre para la creación de productos jurídicos de calidad. Las contribuciones de las constituciones ecuatoriana y boliviana, sin embargo, no son completamente originales, como algunos de sus creadores y promotores han declarado. Estas innovaciones son variaciones que se construyen dentro de la gramática del constitucionalismo moderno; son, por ejemplo, reinterpretaciones de los conceptos de nación, pueblo y cultura. Sin embargo, algunas otras de sus contribuciones, aunque parten de la gramática del constitucionalismo moderno, van más allá de ella, por ejemplo, el principio del buen vivir. Este artículo describe y analiza los tres componentes que hacen de las constituciones de Bolivia y Ecuador constituciones multiculturales y ambientales. En primer lugar, analiza la idea de que las comunidades indígenas deben ser reconocidas como naciones y la idea de que la comunidad política debe construirse mediante la interacción entre sus diversos grupos culturales. Luego, el artículo explora las formas tradicionales de pensar sobre la naturaleza y sus conexiones con el concepto moderno de derechos con las que están comprometidas las comunidades indígenas andinas; más precisamente, explora la idea de que la naturaleza es un sujeto de derechos. Finalmente, el artículo examina la forma en que el principio del buen vivir concibe la relación entre los seres humanos y la naturaleza.
Principio de destino: alcance de los mecanismos para el recaudo del iva en la prestación transfronteriza de servicios
Authors: Pava Ramírez Judith
Published: November 2018

La Reforma Tributaria Estructural, Ley 1819 de 2016, introdujo modificaciones importantes en el hecho generador del IVA, entre estas, la del literal b) del artículo 420 del Estatuto Tributario, que incorporó la aplicación del principio de destino en la prestación de servicios desde el exterior, entendiendo que estas se encuentran sujetas a imposición cuando el destinatario y/o usuario del servicio estén localizados en el territorio nacional, adecuando de esta forma la norma fiscal a nuevos fenómenos que se encontraban libres de impuestos, entre ellos la economía digital. Dentro de los desafíos que debe afrontar la Administración Tributaria está el de asegurar la efectividad del recaudo cuando el responsable del IVA es el prestador del servicio en el extranjero, tema que se aborda en el presente trabajo a través del análisis de los mecanismos de recaudo propuestos por la OCDE y sobre los que se plantean alternativas de solución.

Published: November 2018

This article is intended to analyse the values and is based on the problematic issues: What are the educational factors that influence the formation of values in modern organizations? What is education of value dependency on the educational, social and environmental factors? How users of the service perceived values? In order to respond to the problematic issues it is raised an assumption that in organization of service use, values contextualisation aspect is very important. Value system is characterized not only by common characteristics, but also by individuals. The canter of all values is human-being. Making sense of values durability, resistance to time, the necessity of continuity, it is recommended this ideal system, where universal, eternal values are on the top. Values of these days for future generations may seem strange and without meaning, but to live without values is impossible. The importance of personal and social values indicate individual each person norm, which consists of its principles, needs and ideals. Values education is an integral part of each learning organization that promotes human development.

Published: November 2018

Con la apertura de nuevos mercados basados en el conocimiento, cobra importancia el desarrollo de marcas que vayan a tono con el estilo de vida de cada consumidor, un reto para las pymes que siempre han subestimado su capacidad de construir su propia identidad corporativa. El objetivo de este documento es analizar cómo a través del reposicionamiento de la marca, se puede lograr la competitividad de las empresas sin importar el tamaño del negocio, solamente considerando la indagación constante del mercado. Se desarrolló un estudio descriptivo donde se definieron tres categorías de análisis: reposicionamiento como estrategia, la construcción de la marca y la competitividad en las pymes. Estas categorías se identificaron en 54 documentos, correspondientes a artículos científicos, libros y proyectos de grado recuperados de bases de datos académicas. Se concluye que reposicionar una marca amerita el diseño e implementación de sistemas de planeación, comunicación y monitoreo, en donde todas las áreas de la organización participan, con miras a enfocar sus actividades económicas y/o sociales en función de uno o varios mercados.
Food Chemicals Induces Toxic Effect on Health: Overview
Authors: Mukta Sharma  , Anupama Rajput  , Chhaya Rathod  , Shobharam Sahu
Published: November 2018

Production of food and its preservation for long time may involve addition of chemicals. Hence, chemical substances can play an important role in food production and preservation. For.e.g. the additives in the food prolong the shelf life of foods; colours, make food more attractive. Flavouring agents like aldehydes make food tastier. Unlike any other industry, agriculture is also a part of industry. The agriculture industry relies heavily on large number of chemicals which may be toxic in nature. Some of these chemicals may get absorbed by our body. Accordingly the use of chemicals involved in production, harvesting (collection), processing, packing, transport, marketing and consumption creates deleterious effect on both human and ecology. Majority of the additives in the food may lead to headache, nausea, weakness and difficulty in breathing. The research on nerve cells has shown these chemicals to cause toxic effect on nerve cells. Although the toxicants cannot be avoided, but the level can be reduced by adopting or making use of organic, sustainable and less toxic options.

In this proposed work, the feeding behavior of cow is analyzed to monitor its health condition, through the detection of three most common events of grazing activity such as chew, bite, and chew–bite. A healthy cow should have a good means of chew, bite, and chew–bite habits. Hence, an unhealthy cow can be easily identified by its grazing activities and treated immediately. Here, a wearable and compact device is developed, which is used to monitor the grazing events. The device consists of Arduino uno, Accelerometer sensor, Wi-Fi module, and a battery for power supply. This helps the cattle owners to monitor the cattle condition at remote distance via wireless communication. The device was placed on 30 cows and 65 real-time datasets were recorded in which 30 datasets indicated bite event, 26 datasets indicated chew event and 14 datasets indicated chew–bite event and it was verified.

In this paper, we report a detailed description of developed Flex-SPI firmware structure together with experimental tests carried out by using ad-hoc instrumental setups based on TI MSP- EXP430F5438 experimenter boards. Developed framework, aimed to provide a solid base to test the possibility of performing a shared SPI communication with a fixed number of wires without renouncing to push-pull output stage advantages, has been implemented and successfully validated. Also, FlexSPI energy consumption has been evaluated and then compared with the I2C one, by proper experimental setups and related data processing: the two protocols, in fact, share several features, although they rely on a different hardware configuration. The energy/bit metric was chosen so that the two output stages can be compared regardless the effective quantity of exchanged packets; thus, this measure provides an indication of necessary energy amount to move a single bit to guarantee the correct firmware functionality. Despite larger quantity of exchanged data due to channel reservation needs (with a 35% traffic overhead, in the performed tests), the FlexSPI total energy consumption is comparable with the I2C one, at the same communication speed; thus a lower energy/bit requirement is required for FlexSPI protocol, decreasing with the negotiated speed, in this way proving FlexSPI protocol as a suited and valid choice for high-speed low-consumption communications inside embedded systems with a developed architecture capable of great flexibility.

Object based classification plays an important role in every field. Support vector machine is the popular algorithm for object based classification. Support vector machine classifies the data points using straight line. Some datasets are impossible to separate by straight line. To cope with this problem kernel function is used. The central idea of kernel function is to project points up in a higher dimensional space hoping that separability of data would improve. There are various kernels in the LIBSVM package. In this paper, Support Vector Machine (SVM) is evaluated as classifier with four different kernels namely linear kernel, polynomial kernel, radial basis function kernel and sigmoid kernel. Several datasets are being experimented to find out the performance of various kernels of SVM .By changing the value of ‘C’ and γ varying results are observed. Among these RBF kernel with a value of C = 1000 and gamma=0.75 got an excellent accuracy of 99.1509%.The SVM-RBF kernel gave an edge over the other kernels with an accuracy of 99.1509% while linear at 98.9623%, polynomial at 98.6792% and Sigmoid at 98.5849%.

Published: November 2018

The advanced monitoring and control applications consider Wireless Sensor Networks (WSN) as a promising technology for modern applications like the Internet of Things (IoT), Smart Grid and Wireless Body Area Networks (WBAN). The WSN has important features like less cost, low power usage, supportable data rates and complexity. There is a need for continuous research on improving characteristics and abilities of WSN. The reliable performance of WSN depends on the latency necessities depending on the type of application and Quality of Service (QoS) parameters. The technologies like Zigbee, WiFi, and Bluetooth operating in 2.4GHz are mostly considered for deploying the WSN. Because of coexistence environment, the performance of Zigbee gets affected in terms of channel switching and causes the significant amount of delay. Also, the data transmission should be performed without any collision. In this paper, initially, the pseudorandom – based interference evading scheme is introduced for efficient data communication. During this scheme, if node attains a channel it must wait for a network reconfiguration time for moving to next channel. Hence, during this time other nodes are allowed for moving to the new channel. Secondly, for moving to the new channel load aware channel estimation is proposed to assess the possibility of traffic weight assignment at each channel. Finally, the Particle swarm optimization (PSO) based collision avoiding multiple-channel based superframe scheduling is proposed for IEEE 802.15.4 based wireless networks working under the influence of IEEE 802.11b network. The channel with best energy function is selected for data transmission. The work proposed in this paper is evaluated based on the comparison to the existing works. From the results obtained it is inferred as proposed work shows better performance in terms of packet error rate, packet delivery ratio, and energy consumed when compared to the existing algorithms.

Home Energy Management System (HEMS) is standard as a system for reducing power consumption in ordinary homes. The system prevents the users from forgetting to turn off home appliances. However the system is too simple to more reduce power consumption. Therefore we aim to reduce power consumption by figuring out a user’s behavior to control home appliances. However to estimate user’s behavior is difficult for the system. So we develop Multifunction Outlet System into a function to control home appliances. The function uses Ward’s method which is an unsupervised learning for estimation of a user’s behavior. In this paper, we evaluated a result of estimate of a user’s behavior from sensor data by Ward’s method.
