The link between the domestic market concentration and export performance was studied before, but there is no unilateral approach to how they affect each other. In the case of South Korea there is the evidence that high domestic concentration increases its international competitiveness. In this work we are checking this notion with the usage of the five-digit industry panel data for the period 1990-2018. Ordinary least squared with fixed effects are used as the main model and later the obtained results are being checked with the implementation of the two-stage-least-squares, accounting for the possibility of the simultaneity bias between competition on the domestic market and global performance. The final results show that over the years Korean market has matured and now high concentration and absence of competition are hurtful to the industrys exports. Moreover, additional variables of labor productivity and research and development intensity are positively related to the international performance and should be supported by the governmental policies and individual company efforts.Introduction 5 1.

Gestures and Lexical Access Problems in German as Second Language

Màster de Lingüística Aplicada i Adquisició de Llengües en Contextos Multilingües, Departament de Filologia Anglesa i Alemanya, Universitat de Barcelona, Curs: 2015, Tutora: Marta Fernandez-VillanuevaGestures receive growing attention in the field of Second Language Acquisition but still there is a scarcity of research that looks at them as a part of multimodal communication through the use of interactional approach. The present study aims to explore the interplay of gestures in oral production in German as second language and the lexical access problems. It looks at the principal gesture functions in communication (referential, discursive, interactional, autostimulative) and adapts the NEUROGES typology by Lausberg and Sloetjes (2009) who distinguish gestures that depict image, conventional, emotional, pointing, emphatic, autostimulative gestures The purpose of the study is to see what kind of gestures occurs with the lexical access problems in German SL oral communication and if any gestural types depend on L2 proficiency and fluency. To answer these research questions the speech of 6 Spanish/Catalan (L1) students of German (L2) was analyzed. The participants varied in their proficiency (intermediate, upper-intermediate, advanced levels) and fluency. The data were taken from the VARCOM Corpus of the University of Barcelona. There were the videotaped dialogues between the students of German and German native speakers who participated in communication and were instructed to prompt the information from their interviewees during the argumentation task. During the analysis the cases with lexical access problems in speech, the involved lexical items (abstract or concrete) and the hand gestures were identified and coded in the ELAN annotator device. The study reflects on the tendencies in the gestural trajectory and dynamics, the start-time of gestures regarding to the target word (before, together, after it) and the principal communicative functions of gestures at the moments of word-searches in speech..

Post - sedimentation influence on filtration capacity reservoir rock properties (Pur-Tazov oil\gas-bearing area)

The processes of the second mineral formation (kaolinite, carbonates and micas) were identified during the post-sedimentation transformation studies in oil\gas deposits. Besides, quartz regeneration, solid product destructive formation processes and hydrocarbon oxidation processes were -determined. Correlation analysis of the mineralogy and petrophysics data revealed the post-sedimentation influence factors on the reservoir properties of deposits. It should be noted that the second kaolinite composition increase results in water saturation and density decrease, porosity and, especially, permeability increase. Quartz regeneration and second mica formation deteriorate the reservoir properties or poorly influence them. The hydrocarbon decay and oxidation products, as well as secondary carbonate seal the void space, replace the soluble rock debris and sharply deteriorate the reservoir properties of oil andgas deposits

Acquired heart defects: Clinical picture, diagnosis

In acquired heart defects, they are defined as the occurrence of an irreversible violation in its structure, that leads to a complete loss of its function, changes in intracardiac hemodynamics, as well as change in intracardiac hemodynamics, as a result of which there is an overload of the corresponding parts of the heart, hypertrophy and dilatation of the chambers and circulatory disorders throughout the body. The main causes of valvular heart disease formation: the hereditary connective tissue disorder (mitral valve prolapse, leading to severe mitral insuficience) and other connection tissue disorders (mitral valve prolapse leads to severa mitral insufficiency) • infectious or rheumatic endocarditis

Predictores del bienestar psicológico de los estudiantes universitarios de arte y cultura

The study investigated the predictors of psychological well-being of the art and culture of university students. Predictors of psychological well-being are psychological culture and its psychological variables: the ability to reflect, the ability to be a subject (subjectness) and creativity. This was an empirical study that collected data through a questionnaire. The results of the research showed the influence of psychological culture on the level of well-being of the University students. Personal variables “subjectness”, “reflexivity” and “creativity” were used in the regression analysis to predict the values of the variable “psychological well-being”. It is established that these variables are predictive: their severity is a prognostically significant feature in the analysis of the psychological well-being of the art and culture of university students. Reflexivity means the strongest prediction in relation to the level of psychological well-being.El estudio investigó los predictores del bienestar psicológico del arte y la cultura de los estudiantes universitarios. Los predictores del bienestar psicológico son la cultura psicológica y sus variables psicológicas: la capacidad de reflexionar, la capacidad de ser sujeto (subjetividad) y la creatividad. Este fue un estudio empírico que recolectó datos a través de un cuestionario. Los resultados de la investigación mostraron la influencia de la cultura psicológica en el nivel de bienestar de los estudiantes universitarios. Las variables personales “subjetividad”, “reflexividad” y “creatividad” se utilizaron en el análisis de regresión para predecir los valores de la variable “bienestar psicológico”. Se establece que estas variables son predictivas: su gravedad es una característica pronósticamente significativa en el análisis del bienestar psicológico del arte y la cultura de los estudiantes universitarios. La reflexividad significa la predicción más fuerte en relación con el nivel de bienestar psicológico

Complex Processing of Adsorbent Used in the Purification of Hydrogen-Containing Gas

The problems of processing spent adsorbents with a high concentration of chemisorbed chlorine-containing compounds for their reuse are studied in this article. The genesis of the phase composition and morphology at all technological stages of thermochemical regeneration of the spent adsorbent - Axstrap-860 by means of alkaline modification with a combined solution of sodium and potassium hydroxides has been tested by diffractometry and elemental analysis. The results show that the formation of a layer with an increased concentration of alkali metals in the form of the corresponding carbonates and NaOH on the surface of the granules and in the volume of sodium and potassium aluminates provides adsorption of HCl, which are slightly inferior to the fresh adsorbent. The conditions for the removal of halogen-containing substances from technogenic raw materials with the subsequent isolation of useful products have been optimized: (1) crystalline NaCl intended for the preparation of electrolyte for electrode boilers and steam generators; (2) a mixture of chlorides and hydroxochlorides of aluminum tested in the process of coagulation purification of turbid natural and waste waters; (3) pseudoboehmite for the production of an adsorbent-desiccant and the synthesis of magnesium-aluminum spinel using the technology of destruction-epitaxial transformation, and a promising carrier for catalysts for steam reforming of hydrocarbons.

Effect of the Bone Marrow Mesenchymal Stromal Cells Cytokine-Producing Activity on the Hematopoietic Ste

Hematopoietic stem cell transplantation is used to treat hemoblastoses and some other diseases. Depending on the diagnosis, autologous cells of the patient or allogeneic cells obtained from a healthy related or unrelated donor are used. A sufficient count of harvested hematopoietic progenitor cells is necessary for successful transplantation. Currently, stimulation of their egress from the bone marrow into the peripheral blood by a granulocyte colony-stimulating factor, followed by collection by leukapheresis, is widely used for their preparation. Hematopoietic stem cells leave the bone marrow niche formed by the stromal microenvironment when their holding bonds are interrupted. Mesenchymal stromal cells regulate the release of hematopoietic precursors by producing various cytokines and other biologically active substances. Therefore, the study of the functional properties of bone marrow mesenchymal cells can help in solving the problem of “poor” mobilizations that occur in patients with multiple myeloma.The aim of the study was to estimate the effectiveness of mobilization of hematopoietic stem cells depending on the cytokine-producing ability of mesenchymal stromal cells in the bone marrow of donors and patients with multiple myeloma.The yields of hematopoietic progenitors were studied in 10 donors (median age 27 years) and 18 patients with multiple myeloma (median age 57 years). In donors, the release of hematopoietic stem cells into the peripheral blood was stimulated by subcutaneous administration of G-CSF at a dose of 10 μg/kg/day. Patients with multiple myeloma received vinorelbine at a dose of 35 mg/m2 of body surface, followed by administration of G-CSF (10 μg/kg/day subcutaneously). A culture of mesenchymal stromal cells was obtained from bone marrow taken prior to mobilization and the content of interleukins IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10, TNF-α and IFN-γ in supernatants was studied by enzyme-linked immunosorbent assay using kits of reagents produced by Vector-Best (Novosibirsk).Patients with multiple myeloma were characterized by high secretion of the pro-inflammatory cytokine IL-2 (4.70 pg/ml vs 3.55 pg/ml in healthy individuals, p=0.003) and low IFN-γ (0.41 pg/ml vs 2.14 pg/ml in healthy, p<0.001), but no relationship was found between these cytokines and the hematopoietic stem cells yield. The present study showed that in patients with ineffective harvesting of hematopoietic precursors, secretion of IL-8 by stromal cells was low (308.08 pg/ml vs 561.29 pg/ml in healthy individuals, p=0.04).The obtained results are consistent with the literature data on the important role of IL-8 in the mobilization of hematopoietic stem cells, which allows to consider IL-8 as an informative marker for predicting the insufficient yields of hematopoietic precursors

Perception of Time Perspective in Substance-Dependent Individuals

Background. The perception of time perspective in substance-dependent individuals is considered as a dynamic characteristic of the personality, which can be both a predictor of the effectiveness of self-determination in life and a risk factor for further abuse of alcohol and drugs. Assisted forming of a balanced time perspective and a positive attitude toward all time dimensions has the potential to improve rehabilitation programs and the effectiveness of psychological interventions for substance-dependent individuals. Objective. The article aims to summarize the most significant published current national and international research on the topic of time perspective perception in substance-dependent individuals. An analysis of current directions and prospects for further study of the problem are suggested. Methods. The selection and analysis of studies of the last 10 years on the topic of time perspective in substance-dependent individuals were carried out. Results. A scientific review of studies was carried out in the following areas: 1) time perspective in substance-dependent individuals; 2) possibilities of psychological intervention for time perspective modification. Conclusion. The analysis of scientific publications has shown that a time perspective in substance dependence is a relevant area of international research. Based on the findings, methods and approaches of psychotherapeutic assistance to substance users in the process of their rehabilitation are being developed and improved. Russian research on the time perspective of substance users is represented by a small number of studies, which mainly consider imbalanced temporal orientations as a risk factor for relapse into addictive behaviour. A multi-faceted study of temporal perspective and its balance at different stages of rehabilitation has the potential to improve the effectiveness of psychotherapeutic work
