Published: September 2019

The present study was undertaken to evaluate of Nigella sativa oil (NSO) and zinc-silver cream in a rat model of wound healing by means of clinical appearance, histopathology, oxidative stress parameters, and biomechanical tests. The rats were divided into three groups, each having twenty animals. Group 1 served as a control having wound. Other two groups received either NS oil or zinc-silver cream in addition to the wound. The study was initiated after the animals rested for 2 weeks for acclimation. Blood samples were collected from 10 randomly selected animals from each group at days 0, 3, 7 and 14 for oxidative stress measurements. Differences among groups for blood lipid peroxidation and antioxidant values were determined with respect to biochemical oxidative stress results (P&lt;0.01). Wound sites of 10 animals from each group were allocated for histopathological examinations, and those of the remaining 10 animals from each group were used in biomechanical testing. Histopathological examination revealed that epithelization occurred in all groups. Inflammatory response with an intensive vascularization was present in the samples of the silver group (P&lt;0.01). Consequently, zinc-silver group has differed positively in terms of biochemical and biomechanical and histological aspects compared to other groups for wound healing and oxidative stress.

ResumenLas concepciones para la orientación psicopedagógica deben asumirse como uno de los retos para el perfeccionamiento de la práctica universitaria; con énfasis en el nivel institucional y los colectivos de carrera. La identificación de esta problemática permitió analizar las reflexiones teóricas que configuran la posición metodológica de las acciones que se proponen en el artículo. El resultado de este proceso se viene enriqueciendo de manera gradual a partir de la estrategia institucional de manera que las tareas o actividades descansen en una concepción integral del proceso formativo en íntima relación con las demás áreas de servicio y de dirección. La experiencia desarrollada en los últimos dos semestres en la UMET, permitió establecer el procedimiento que debe regir las acciones educativas para que estas impacten en la práctica universitaria hasta alcanzar el nivel de integración, coherencia y sistematicidad que se precisa en este tipo de orientación. Las concepciones que se presentan ponderan la responsabilidad en el trabajo metodológico y de vinculación; así como la importancia de especificar la intencionalidad de este proceso en el diseño y desarrollo del currículo.Palabras claves: orientación psicopedagógica, carrera, formación, estrategias, currículoAbstractConceptions for psycho-pedagogical orientation should be assumed as one of the challenges for the improvement of university practice; with emphasis on the institutional level and career groups. The identification of this problem allowed to analyze the theoretical reflections that configure the methodological position of the actions proposed in the article. The result of this process has been gradually enriched from the institutional strategy so that the tasks or activities rest in a comprehensive conception of the training process in intimate relationship with the other areas of service and management.

Published: September 2019

The presented study examines the speciﬁc aspects of operation of energy enterprises in the Arctic zone of the Russian Federation.Aim. The study aims to identify the current problems in the operation of energy enterprises in the Arctic territories by analyzing their state and development and thus to substantiate the selection of perspective directions for improving the efﬁciency of their management.Tasks. The authors show the role and importance of energy supply for the functioning of the socioeconomic system of the Arctic territories, analyze the major performance indicators of energy enterprises, and substantiate recommendations on improving the organization of their activities.Methods. This study uses the methodology of economic analysis, trend analysis, structural analysis, and speciﬁc methods of regional economic analysis.Results. One of the crucial current problems in the development of the energy complex in the Russian Arctic zone is the high level of debt in the accounts, which leads to an imbalance in the current activities of energy enterprises. Furthermore, formation of electricity tariffs depends on the money paid for the generation and transportation of electricity and the services of distribution companies. This is due to the lack of continuous monitoring of the state of accounts and the lack of a legal framework for settling differences between network and energy supply companies, which are not given sufﬁcient attention in economic studies.Conclusions. According to the results of the study, the authors propose the major directions for improving regulation of the development and operation of energy enterprises in the Arctic zone of the Russian Federation.

Published: September 2019

The presented study examines methodological approaches to poverty assessment as a social indicator of economic security of Russian regions and countries of the Eurasian Economic Union (EAEU).Aim. The study aims to analyze the level of poverty in Russian regions, including in relation to the dynamics of inequality indicators.Tasks. The authors address the problems of developing a comprehensive approach to poverty assessment in Russia with a view to further develop public policy measures that would allow for a radical reduction in poverty and analyze the dynamics of the poverty level indicator in the EAEU countries, determining the distinctive features of this phenomenon in the countries that are most economically integrated with Russia.Methods. This study uses the methods of systems analysis, econometric analysis, evolutionary-institutional theory, and historical approach.Results. Analysis of the absolute poverty indicator in regions shows a signiﬁcant disparity between regions in terms of the proportion of citizens with incomes below the absolute poverty line. In all EAEU countries, the level of poverty decreased over the past 12 years, but the dynamics of this indicator is diverging.Conclusions. It is not uncommon for the regions of the Russian Federation with lower absolute poverty to have a higher Gini coefﬁcient. EAEU countries use different methods for calculating the poverty level. Looking ahead, it seems appropriate to standardize the methodology for calculating poverty levels in EAEU countries, introduce a uniform standard for calculating this indicator, and develop joint comprehensive measures aimed at reducing poverty in EAEU member states.

The presented study aims to examine the current state and development prospects of self-regulation in the Russian construction industry.Aim. The study aims to conduct a comprehensive analysis of the current state and development prospects of self-regulation as an institution of public administration, identify the problems of self-regulation in the construction industry, and formulate proposals on solving the identiﬁed problems.Tasks. The authors complete the following tasks to achieve the set aim: examine the regulatory framework of the activities of self-regulatory organizations in the construction industry — construction, design, and engineering surveying; analyze the current state and positive trends of self-regulation in the ﬁeld of construction; identify problems in the activities of self-regulatory organizations in the construction industry — construction, design, and engineering surveying — and development prospects of the examined alternative to government regulation.Methods. The methodological basis of the study comprises the fundamental provisions of the modern economic theory, theories of public and municipal administration and legal sciences. The information base includes regulatory and legal acts of the Russian Federation on self-regulation in the construction industry, data from the State Register of Self-Regulatory Organizations, and statistics in the ﬁeld of construction.Results. At the current stage of development of self-regulation in the construction industry, the most efﬁcient mechanism for this institution involves guaranteed compensation for damage caused due to shortcomings in the works and services during construction, renovation, capital repairs of construction objects, engineering surveying, design. The victims should be compensated not out of insurance payments under civil insurance contracts, but rather out of the compensation funds of self-regulatory organizations.Conclusion. This study makes it possible to assess the institution of self-regulation in the construction industry — construction, design, and engineering surveying — as an efﬁcient institution for proper protection of the interests of consumers of construction works and services and those of the government.
The Methodology for Developing an Innovation Based on Co-Creation and Co-Production

Published: September 2019

Aim. The presented study aims to improve the quality function deployment methodology in innovation development with allowance for the principles of the value co-creation methodology.Tasks. The authors analyze the essence of the value co-creation concept in innovation development, examine the quality function deployment (QFD) methodology as a basic tool for the development of competitive incremental innovations, and propose their own revised methodology that combines the elements of co-creation and co-production on the part of the consumer.Methods. The methodological basis of the study comprises the scientific concepts of economic theory and innovation theory. This study also uses such general scientific methods as systems and complex approach, economic and statistical analysis to substantiate theoretical assumptions and rationalize the conclusions.Results. The authors recommend using a digital double of the developed innovation (product or technology) during quality function deployment. The usefulness of the digital double is confirmed by an example from one of the authors’ practice. During the development of the so-called technical benchmarking rooms for an innovation, the authors propose calculating competitiveness based on a customer satisfaction index (CSI). The classical quality function deployment methodology makes it possible to assess the superiority/lag of the developed innovation compared with the existing prototypes along a number of parameters. Calculation of the CSI indicator makes it possible to assess the developed innovation in terms of its conformity with the customer’s ideal, and give an indication of its overall superiority/lag in comparison with the existing prototypes. The authors propose a modification of the organizational structure, which is supposed to be engaged in the development of a competitive innovation based on the value co-creation methodology. In addition to the roles of developer, financial analyst, and marketer, a representative of the customer (buyer of innovation) is introduced into the group. Representatives of suppliers with long-term contracts are planned to be involved in the group’s work. As a whole, this type of organizational structure results in a significant synergistic effect of cooperation within the “supplier — manufacturer/developer — end consumer” system.Conclusions. This study proposes a modification of the quality function deployment methodology with allowance for additional customer preferences as well as production and service functions that the customer is ready to take on.
Effects of Play Therapy on the Pain Management of Post-Operative Pediatric Patients
Authors: Dorado Mary Ann 
Published: September 2019

Studies on play therapy in other disciplines have been done but post-operative pain management in pediatric patients has not been considered. This study determined the effects of play therapy using storytelling, bubble blowing, singing and film viewing on the pain management of post-operative pediatric patients. The single-group pretest-posttest design was employed. Post-operative pediatric patients of the orthopedic ward ages 2-7 years old assessed to have acute pain were chosen; seven out of 12 patients qualified and were given a pretest to assess the level of pain. Experimental treatment was administered; a posttest was administered thereafter. The level of pain was assessed before and after the intervention with the use of Wong-Baker FACES Pain Rating Scale, FLACC technique scale to assess the behavior and assessment of the vital signs. Play was used as the intervention and significant differences in the level of alleviated pain using self-assessment was computed by getting the decrement level of pain from pre to post assessment and subjecting it to the Kruskal-Wallis test. Storytelling was found to be the most effective resulting to lowered respiratory rate, heart rate and a normal blood pressure reading; however, it did not prove statistical significance as indicated by p-values greater than the 0.05 alpha level. Computed W coefficients associated with p-values revealed that pre-assessment data results were statistically different from the post-assessment data results in terms of self, behavioral and physiological assessments across the four types of play. The pain decrement from the pretest to posttest was statistically significant. A pain management program was proposed.

A Catalog of Hyper-luminous X-Ray Sources and Intermediate-mass Black Hole Candidates out to High Redshifts
Authors: Barrows R. Scott , Mezcua Mar , Comerford Julia M. 
Published: September 2019

Abstract
Hyper-luminous X-ray sources (HLXs; L
X > 1041 erg s−1) are off-nuclear X-ray sources in galaxies and strong candidates for intermediate-mass black holes (IMBHs). We have constructed a sample of 169 HLX candidates by combining X-ray detections from the Chandra Source Catalog (Version 2) with galaxies from the Sloan Digital Sky Survey and registering individual images for improved relative astrometric accuracy. The spatial resolution of Chandra allows for the sample to extend out to z ∼ 0.9. Optical counterparts are detected among one-fourth of the sample, one-third of which are consistent with dwarf galaxy stellar masses. The average intrinsic X-ray spectral slope indicates efficient accretion, potentially driven by galaxy mergers, and the column densities suggest one-third of the sample has significant X-ray absorption. We find that 144 of the HLX candidates have X-ray emission that is significantly in excess of the expected contribution from star formation and hot gas, strongly suggesting that they are produced by accretion onto black holes more massive than stars. After correcting for an average background or foreground contamination rate of 8%, we estimate that at least ∼20 of the HLX candidates are consistent with IMBH masses, and this estimate is potentially several times higher assuming more efficient accretion. This catalog currently represents the largest sample of uniformly selected, off-nuclear IMBH candidates. These sources may represent scenarios in which a low-mass galaxy hosting an IMBH has merged with a more massive galaxy and provide an excellent sample for testing models of low-mass BH formation and merger-driven growth.
Distances to Galactic OB Stars: Photometry versus Parallax
Authors: Shull J. Michael , Danforth Charles W. 
Published: September 2019

Abstract
For application to surveys of interstellar matter and Galactic structure, we compute new spectrophotometric distances to 139 OB stars frequently used as background targets for UV spectroscopy. Many of these stars have updated spectral types and digital photometry with reddening corrections from the Galactic O-Star (GOS) spectroscopic survey. We compare our new photometric distances to values used in previous International Ultraviolet Explorer and Far Ultraviolet Spectroscopic Explorer surveys and to parallax distances derived from Gaia-DR2, after applying a standard (0.03 mas) offset from the quasar celestial reference frame. We find substantial differences between photometric and parallax distances at d > 1.5 kpc, with increasing dispersion when parallax errors exceed 8%. Differences from previous surveys arise from new GOS stellar classifications, especially luminosity classes, and from reddening corrections. We apply our methods to two OB associations. For Perseus OB1 (nine O stars) we find mean distances of 2.47 ± 0.57 kpc (Gaia parallax) and 2.99 ± 0.14 kpc (photometric) using a standard grid of absolute magnitudes. For 29 O stars in Car OB1 associated with Trumpler 16, Trumpler 14, Trumpler 15, and Collinder 228 star clusters, we find 2.87 ± 0.73 kpc (Gaia) and 2.60 ± 0.28 kpc (photometric). Using an alternative grid of O-star absolute magnitudes shifts these photometric distances ∼7% closer. Improving the distances to OB stars will require attention to spectral types, photometry, reddening, binarity, and the grid of absolute magnitudes. We anticipate that future measurements in Gaia-DR3 will improve the precision of distances to massive star-forming regions in the Milky Way.

Abstract
We collected a large data set of field RR Lyrae stars (RRLs) by using catalogs already available in the literature and Gaia DR2. We estimated the iron abundances for a subsample of 2382 fundamental RRLs (ΔS method: Ca ii K, Hβ, Hγ, and Hδ lines) for which there are publicly available medium-resolution SDSS-SEGUE spectra. We also included similar estimates available in the literature, ending up with the largest and most homogeneous spectroscopic data set ever collected for RRLs (2903). The metallicity scale was validated by using iron abundances based on high-resolution spectra for a fundamental field RRL (V Ind), for which we collected X-shooter spectra covering the entire pulsation cycle. The peak ([Fe/H] = −1.59 ± 0.01) and the standard deviation (σ = 0.43 dex) of the metallicity distribution agree quite well with similar estimates available in the literature. The current measurements disclose a well-defined metal-rich tail approaching solar iron abundance. The spectroscopic sample plotted in the Bailey diagram (period versus luminosity amplitude) shows a steady variation when moving from the metal-poor ([Fe/H] = −3.0/–2.5) to the metal-rich ([Fe/H] = −0.5/0.0) regime. The smooth transition in the peak of the period distribution as a function of the metallicity strongly indicates that the long-standing problem of the Oosterhoff dichotomy among Galactic globular clusters is the consequence of the lack of metal-intermediate clusters hosting RRLs. We also found that the luminosity amplitude, in contrast with period, does not show a solid correlation with metallicity. This suggests that period–amplitude–metallicity relations should be cautiously treated.
