Published: March 2019

Aim of the studyThe aims of the study were to assess whether the Oral Health Related Quality of Life (OHRQoL) is decreased in patients with temporomandibular disorders –myalgic type, to evaluate to what extent myofascial pain intensity affects OHRQoL and to investigate the relationships between cognitive function and OHRQoL.Subject or material and methodsThe study included 45 patients diagnosed with the muscle-related temporomandibular disorders. The study group consisted of twenty three people with painful form of disorder. The control consisted of twenty two people without pain experience. The study was a part of a larger research project. The data to be analyzed for this article was obtained in the course of a single questionnaire survey conducted prior to the start of the treatment process.ResultsThe results show that the study group suffering from myofascial pain experiences related to temporomandibular disorders of myalgic type consistently reported higher quality of life levels than the patient group who reported lack of pain experiences. In principle the better OHRQoL, the poorer cognitive functioning in most neurocognitive domains investigated in the study.DiscussionThe results, however surprising, may indicate specific relationships between factors analyzed in the study. These need to be confirmed with larger sample, taking into account general quality of patients life and psychoemotional factors.ConclusionsOHRQoL of patients with temporomandibular disorders shows a co-variation with certain aspects of cognitive functioning. The results should be considered with a caution that is resulting from the limitations of the research sample.

Aim of the studyThe overall purpose of this study was to examine the relationship between perceived social support and locus and control sub-scales and illness perception in MI patients.Subject or material and methods241 consecutive MI patients participated in this study in 2016-17. Comprehensive questionnaires along with interview were used to collect demographic and clinical information of participants during the first week of hospitalization. Four months later, the information on perceived social support, perceived locus of control subscales, and illness perception of participants was collected at their house. The data was analyzed by structural equation modeling to verify the interrelationships between variables.ResultsThe mean of participants’ age was 54.53 (SD= 9.76) years. The sample consisted of 83% males. Those with better illness perception regarding MI were more prone to be diagnosed as diabetic (p=0.005) and/or may have had better perceived social support (p<0.001) and/or may have had less chance locus of control (P = 0.054).DiscussionDiscussion: The findings of this study showed that among MI patients there is a significant relationship between demographic and clinical characteristics,perceived social support, perceived locus of control sub-scales and illness perception.ConclusionsThe findings of the current study provided an overview of the relationship existed between perceived social support and locus of control and illness perception in myocardial infarction patients. This could help care teams to provide better post MI care in the course of the disease by considering these important psychological factors.

Early Detection of Pancreatic Cancer in High-Risk Individuals: Where Do We Go From Here?
Authors: Hart Phil A. 
Published: March 2019

Abstract
Pancreatic cancer is a lethal disease that is commonly diagnosed at a late stage. Screening asymptomatic patients is necessary for early detection, but this is not currently recommended in the general population. As demonstrated in the current study, an important number of patients at increased risk can be diagnosed using either MRI/magnetic resonance cholangiopancreatography or endoscopic ultrasound. Further collaborative efforts are needed to define the ideal population for testing and refine the current approach to pancreatic cancer surveillance.

Purpose: the aim of our research is the development of the theory and methodology of wages from the position of institutional and complementary approaches which encourage formation and implementation of the compensation model of payment at the corporate level, in the background of which the market price of labor lies, which is determined in the process of interaction of employment relations actors.
Design/methodology/approach: this paper is based on the description and analysis of payment in Russia
Findings: based on the empirical analysis of Russian and foreign literature, the author showed a trend of ‘catching up’ development wages model in Russian’s organizations. The author introduced scientifically based historical allocation of payment model development in Russia and suggested their classification. The conceptual framework of payment institution has been expanded. The conceptual approaches to forming the compensation model of payment at the corporate level have been reasoned. The mechanism of development and implementation of the compensation model of payment at the corporate level has been proposed. It has been proved that the contents of the ‘grading’ process using Western methods of job evaluation is identical to the content of the ‘tariff regulation’ and represents the reducing of labor at the corporate level. Author's definition of a social package has been justified.
Originality/value: the paper discusses and develops conceptual frameworks, theoretical and methodological approaches to payment in Russia in the context of lessons derived from developed countries, as well as the guidelines to improve the mechanism of remuneration at the corporate level with regard to the economic conditions of modernization; the author considers that scientific findings will be of value for companies and their corporate governance.

Issues of sustainability of economic development of individual countries and the world economy in general are becoming more and more relevant, financial and economic relations reveal the global dependence of the economies of all countries.
The article lists the measures taken to stabilize the economy after the world economic crisis of 2007-2008, which began in the US, which subsequently initiated a protracted second wave of the euro zone crisis since 2010.
The key financial and economic indicators of the EU and RF countries are indicated: GDP, Current account balance, External debt stocks, Total reserves (includes gold), Total reserves in months of imports, Net financial account, Net primary income, Net trade in goods and services, Net trade in goods, Exports of goods and services, Import of goods and services.
Relative indicators were used to analyze and compare the different in the territory and number of the 29 EU countries and Russia, the boundaries and the range of their changes (min, max, max-min) were determined. A gradation is proposed for the changes in the financial and economic performance of countries, depending on the level of risk of a crisis in the financial and economic sphere. Particular attention is paid to the dynamics of changes in indicators during the crisis and in 2015-2016. Based on the analysis of financial and economic indicators that characterize the degree of independence of the country from external financial impacts, a rating of the EU and RF countries on the level of risk was composed.

Published: March 2019

The article proposes the author's conceptual logical model of managing the development of local food markets in the context of intermunicipal socioeconomic differentiation, which reflects the course of strategic decision-making in order to achieve a spatial balance of supply and demand for food products, based on the interests of the agents of the regional reproduction cycle of food products. It allows substantiating a set of strategic measures to ensure sustainable development of the region. The algorithm of strategic management of the local food markets’ development in the region has been formed, which includes three consecutive stages. The principles aimed at ensuring a balance of supply and demand of food products in modern conditions have been defined. The necessity to regulate the local food market development in the region has been justified, based on the proposed managerial tools for the development strategizing.
Global Value Chains and Export-Import Determinants in the European Union Member Countries

Published: March 2019

Intra-Eurozone current account imbalances represent one of the most discussed topics related to the competitiveness issues of the common currency area since its establishment. Many authors examined this phenomenon considering possible linkages to effects of common monetary policy, real exchange rates movements, variety of demand drivers (fiscal imbalances included) and capital flows. However, as a result of increasing specialization on the individual country level during past few decades that stimulated distribution of individual stages of production across countries, dynamics of exports and imports of final goods, intermediate goods as well as primary inputs was associated with generally ambiguous effect on the external balance.
The paper investigates the main determinants of disaggregated export and import demand functions on the sample of 21 the European Union member countries. Our results from estimated ARDL model based on the panel data indicates relatively significant importance of intermediate goods in the formation of external trade balances within as well as outside European Union from both territorial and commodity aspects.

Numerous governmental documents refer clusters to instruments for improving the country’s competitiveness. However, the efficiency of creating them is largely defined by theoretical and methodological approaches to estimating and forming their competitiveness. Due to this, the urgency of considering theoretical and methodological issues of creating competitive clusters through the example of the livestock cluster of Kazakhstan and their impact on the competitiveness of the economy of the Akmola Region is growing.
In order to improve the regional policy of the Akmola Region in the livestock sector, it is reasonable to consider the mechanism of uniting all participating entities into a regional meat cluster, the implementation of which can give a powerful impetus to the development of not only the livestock sector in these regions but also to many related industries: trade, processing, transport, etc.

Published: March 2019

The problematic area of this article relates to the current direction of research searching for optimal management tools in the context of global changes in the geopolitical and economic space, as well as large-scale migration. The existing conditions have an extremely high conflict-generating potential, which requires the development of effective tools to stabilize and monitor the situation, to seek ways of civilized resolution of conflicts and contradictions.
The purpose of the article is the identification of mechanisms for optimizing the management process in the context of the transformation of the conflict political space. The authors of the article suggest an innovative approach to the analysis of the phenomenon of transformation of political space at the superstructure level, using a conflict paradigm, as well as systemic and structural-functional approaches. For a productive way of studying management technologies in the context of the transformation of political space, a frame analysis is proposed that allows observing the dynamics of events, including the results of management practices, in the form of a temporary event matrix and a generalized scheme of interpretations by the observer.
The article presents in detail the well-known and new scientific directions dealing with the problems of effective political management, the optimization of the mechanisms for political decision-making, diagnosis, resolution and prevention of conflicts in the socio-economic, ethno-political and other areas, through a comprehensive analysis of the conflictogenesis of a modern socio-political subject. The authors of the article come to the conclusion that the political-administrative elite, the mass media determine the thematization of political-administrative discourse, the dominance in the political media space and the replication of new meanings and symbols. Mechanisms for optimizing the management process, therefore, should be based on developing technologies for managing political risks and emerging spontaneous changes, taking into consideration the presence of unregulated, natural, yet reportable interactions in the sphere of politics, economics and social communications.
Diagenesis and its influence on reservoir quality and oil-water relative permeability: A case study in the Yanchang Formation Chang 8 tight sandstone oil reservoir, Ordos Basin, China

Published: March 2019

Abstract
Different from conventional reservoirs, unconventional tight sand oil reservoirs are characterized by low or ultra-low porosity and permeability, small pore-throat size, complex pore structure and strong heterogeneity. For the continuous exploration and enhancement of oil recovery from tight oil, further analysis of the origins of the different reservoir qualities is required. The Upper Triassic Chang 8 sandstone of the Yanchang Formation from the Maling Oilfield is one of the major tight oil bearing reservoirs in the Ordos Basin. Practical exploration demonstrates that this formation is a typical tight sandstone reservoir. Samples taken from the oil layer were divided into 6 diagenetic facies based on porosity, permeability and the diagenesis characteristics identified through thin section and scanning electron microscopy. To compare pore structure and their seepage property, a high pressure mercury intrusion experiments (HPMI), nuclear magnetic resonance (NMR), andwater-oil relative permeability test were performed on the three main facies developed in reservoir. The reservoir quality and seepage property are largely controlled by diagenesis. Intense compaction leads to a dominant loss of porosity in all sandstones, while different degrees of intensity of carbonate cementation and dissolution promote the differentiation of reservoir quality. The complex pore structure formed after diagenesis determines the seepage characteristics, while cementation of chlorite and illite reduce the effective pore radius, limit fluid mobility, and lead to a serious reduction of reservoir permeability.

Published: March 2019

Abstract
Personal Dead Reckoning based on foot-mounted Inertial Measurement Units is a research hotspot in the field of positioning and navigation in recent years. This paper conducts a targeted research on the application of current mainstream attitude and heading reference system (AHRS) algorithm in the foot inertial navigation positioning. Through open datasets, the positioning accuracy and directional accuracy of 9-state complementary Kalman filter (CKF) are compared and analyzed among the conventional algorithm, Mahony algorithm, and Madgwick algorithm, in which the Madgwick algorithm can achieve the best positioning results. And on this basis, for the Madgwick algorithm, it is verified that it can help improve the positioning accuracy of 15-state CKF under the assistive technologies of zero angular rate update (ZARU) and heuristic heading reduction (HDR). The adaptive zerospeed detection algorithm is designed, and the threshold value of zero-speed detection is set dynamically through tracking the variable of speed in CKF, which can detect the time period of zero-speed state more accurately, thus further improving the correction of directional errors. Finally, the effectiveness of the proposed algorithm is further proved by actual data.

Abstract

Background
Infertile women may have underlying genetic abnormalities. There is, at present, a significant number of studies on the relation between the follicle stimulating hormone receptor (FSHR) or anti-Müllerian hormone type II receptor (AMHRII) polymorphisms and response to in-vitro fertilisation (IVF) treatment. However, it is not yet clear which genotype or combination of genotypes is favourable towards a better ovarian stimulation and pregnancy outcome.

Materials and methods
In this study we assessed the distribution of the genotypes of FSHR Ser680Asn and of AMHRII −482A>G gene polymorphisms in a group of 126 infertile women and a control group of 100 fertile women by using real-time polymerase chain reaction (RT-PCR).

Results
Statistical analysis showed that the frequency of the genotypes is similar in both control and IVF/ intracytoplasmic sperm injection (ICSI) groups. Further investigation of the frequency of the nine possible combinations of these polymorphisms in the groups revealed no correlation between infertility and combination of the polymorphisms. Women with one polymorphism have on average 5.5 units higher levels of AMH compared to women carrying no polymorphism. In women with no polymorphisms, for each unit of FSH increase, the average concentration of blood AMH is expected to be 72% lower.

Conclusion
The distribution of the FSHR Ser680Asn and of the AMHRII −482A>G gene polymorphisms, in the Greek population is similar in fertile and infertile women. The study showed that FSH and AMH correlated levels in certain cases could be used to estimate a patient’s ovarian reserve.
