Authors: Mulualem Getachew Mehabie , Liou Yuei-An
Published: March 2020

The occurrence frequency of drought has intensified with the unprecedented effect of global warming. Knowledge about the spatiotemporal distributions of droughts and their trends is crucial for risk management and developing mitigation strategies. In this study, we developed seven artificial neural network (ANN) predictive models incorporating hydro-meteorological, climate, sea surface temperatures, and topographic attributes to forecast the standardized precipitation evapotranspiration index (SPEI) for seven stations in the Upper Blue Nile basin (UBN) of Ethiopia from 1986 to 2015. The main aim was to analyze the sensitivity of drought-trigger input parameters and to measure their predictive ability by comparing the predicted values with the observed values. Statistical comparisons of the different models showed that accurate results in predicting SPEI values could be achieved by including large-scale climate indices. Furthermore, it was found that the coefficient of determination and the root-mean-square error of the best architecture ranged from 0.820 to 0.949 and 0.263 to 0.428, respectively. In terms of statistical achievement, we concluded that ANNs offer an alternative framework for forecasting the SPEI drought index.
A Normal Cloud Model-Based Method for Risk Assessment of Water Inrush and Its Application in a Super-Long Tunnel Constructed by a Tunnel Boring Machine in the Arid Area of Northwest China
Authors: Wang Xin , Shi Kebin , Shi Quan , Dong Hanwei , Chen Ming
Published: March 2020

Tunnel water inrush is complex, fuzzy, and random, and it is affected by many factors, such as hydrology, geology, and construction. However, few papers have considered the impact of dynamic monitoring on water inrush in previous research. In this study, considering geological, hydrological, and construction factors, as well as dynamic monitoring, a new multi-index evaluation method is proposed to analyze the risk of tunnel water inrush based on the normal cloud model. A new weight algorithm combining analytic hierarchy process and entropy method is used to calculate the index weight. The certainty degree of each evaluation index belonging to the corresponding cloud can be obtained by the cloud model theory. The final level of tunnel water inrush is determined via the synthetic certainty degree. The proposed method is applied to analyze the risk of water inrush in the SS (Shuang-san) tunnel constructed by a tunnel boring machine in the arid area of Northwest China. The evaluation results are not only basically identical to the results calculated by the ideal point and gray relation projection methods, but also agree well with the actual excavation results. This demonstrates that this new risk assessment method of water inrush has high accuracy and feasibility. Simultaneously, it also provides a new research idea to analyze the probability of tunnel water inrush and can provide a reference for related projects.
Evaluating Bank-Filtration Occurrence in the Province of Quebec (Canada) with a GIS Approach
Authors: Patenaude Marc , Baudron Paul , Labelle Laurence , Masse-Dufresne Janie
Published: March 2020

Due to the abundance of surface water in the province of Quebec, Canada, it is suspected that many groundwater wells are pumping a mixture of groundwater and surface water via induced bank filtration (IBF). The regulatory framework in Quebec provides comprehensive guidelines for the development and monitoring of surface water and groundwater drinking water production systems. However, the regulations do not specifically address hybrid groundwater-surface water production systems such as IBF sites. More knowledge on the use of IBF in the province is needed to adjust the regulations with respect to the particularities of these systems. In order to provide a first evaluation of municipal wells potentially using IBF and the corresponding population served by these wells, a Geographic Information Science framework (GISc) was used to implement an IBF spatial database and calculate the distance from each well to the nearest surface water body. GISc is based on open source GIS programs and openly available data, to facilitate the reproducibility of the work. From this provincial scale approach, we show that nearly one million people are supplied by groundwater from municipal wells located <500 m from a surface water body, and half a million have a significant probability to be supplied by IBF wells. A more focused look at the watershed scale distribution of wells allows us to improve our interpretations by considering the aquifer type and other regional factors. This approach reveals strong spatial variability in the distribution of wells in proximity to surface water. Of the three selected regions, one has a high potential for IBF (Laurentides), one requires additional information do draw precise conclusions (Nicolet), and the third region (Vaudreuil-Soulanges) is unlikely to have widespread use of IBF. With this study, we demonstrate that extensive use of IBF is likely and that there is a need for improved understanding and management of these sites in order to properly protect the drinking water supply.
Nexus between Ecological Conservation and Socio-Economic Development and its Dynamics: Insights from a Case in China
Authors: Wu Jian , Guo Yanan , Zhou Jingbo
Published: March 2020

Achieving sustainable socio-economic development in areas designated for ecological conservation is a challenge for many developing countries. The nexus between ecological conservation and socio-economic development is particularly complex in these areas for the reason that most of them are located in poor regions and their resource utilization is constrained by ecological conservation practices. A conceptual framework was proposed for examining the nexus between ecological conservation and economic development in a social-ecological system to explain the pathways and mechanisms of influence between the ecosystem and the social system. We chose the Lashihai watershed in Yunnan Province, China, as the case study area to explore whether a positive feedback loop between ecological conservation and socio-economic development has been formed, as well as how to promote the positive evolution of socio-economic and ecological status. The ecosystem and socio-economic system in the Lashihai watershed closely interact and form a dynamic system with a positive evolutionary trend. If negative factors, such as an uneven distribution of income and new population pressures, are not appropriately managed, they are likely to break the positive feedback loop and trap the system in a negative feedback loop. We discuss the main factors that contribute to the interactions between ecological conservation and livelihoods, and develop policy recommendations for governments in other countries and regions to promote conservation and better livelihoods in conjunction.

Authors: Ferreira C.S.S. , Walsh R.P.D. , Kalantari Z. , Ferreira A.J.D.
Published: March 2020

Understanding sediment dynamics in peri-urban catchments constitutes a research challenge because of the spatiotemporal complexity and variability of land-uses involved. This study investigates differences in the concentration of total sediments (TSC) and suspended sediments (SSC) in the small peri-urban Mediterranean Ribeira dos Covões catchment (40% urban area) in central Portugal. Suspended sediment responses at the catchment outlet (E) and in three upstream sub-catchments, during periods of urbanization (2011–2013) and stabilizing land-use (2017–2018) are compared for storm-event datasets encompassing similar ranges of rainstorm sizes and antecedent rainfall condition. The Quinta sub-catchment, with the lowest urban area (22%) but subject to major construction activities affecting 17% of its area, led to highest TSC and SSC during urbanization (attaining 4320 mg/L and 4184 mg/L, respectively), and a median reduction of 38% and 69%, respectively, during stabilization. Espírito Santo sub-catchment, with highest urban area (49%) and minor construction activities, displayed similar median TSC in both periods (258–240 mg/L) but highest SSC reduction (76%), highlighting the impact of the anthropogenic disturbance mainly on fine-particle sediments and a good connectivity with the stream. Porto Bordalo sub-catchment, with 39% urban area and subject to the construction of a four-line road covering 1.5% of its area, showed the lowest TSC and SSC concentrations and the lowest median reductions in both periods (31% and 64%, correspondingly), mainly because of the impact of an unplanned retention basin established with soil from the construction site. Overall, median TSC and SSC reduced 14% and 59% at E, from urbanization to stabilization. Information about sediment dynamics should guide stakeholders in establishing strategies to reduce sediment loads and mitigate the impacts on urban aquatic ecosystems.

Published: March 2020

This study evaluates the effect of climate change on reference evapotranspiration (ET0), which is one of the most important variables in water resources management and irrigation scheduling. For this purpose, daily weather data of 30 Iranian weather stations from 1981 and 2010 were used. The HadCM3 statistical model was applied to report the output subscale of LARS-WG and to predict the weather information by A1B, A2, and B1 scenarios in three periods: 2011–2045, 2046–2079, and 2080–2113. The ET0 values were estimated by the Ref-ET software. The results indicated that the ET0 will rise from 2011 to 2113 approximately in all stations under three scenarios. The ET0 changes percentages in the A1B scenario during three periods from 2011 to 2113 were found to be 0.98%, 5.18%, and 12.17% compared to base period, respectively, while for the B1 scenario, they were calculated as 0.67%, 4.07%, and 6.61% and for the A2 scenario, they were observed as 0.59%, 5.35%, and 9.38%, respectively. Thus, the highest increase of the ET0 will happen from 2080 to 2113 under the A1B scenario; however, the lowest will occur between 2046 and 2079 under the B1 scenario. Furthermore, the assessment of uncertainty in the ET0 calculated by the different scenarios showed that the ET0 predicted under the A2 scenario was more reliable than the others. The spatial distribution of the ET0 showed that the highest ET0 amount in all scenarios belonged to the southeast and the west of the studied area. The most noticeable point of the results was that the ET0 differs from one scenario to another and from a period to another.
Legionellosis and Recent Advances in Technologies for Legionella Control in Premise Plumbing Systems: A Review
Authors: Carlson Kelsie M. , Boczek Laura A. , Chae Soryong , Ryu Hodon
Published: March 2020

This review discusses Legionella, among the most prolific and publicly well-known waterborne pathogens, and advances in potential treatment technologies. The number of cases associated with Legionella continues to rise, as does its public awareness. Currently, cases associated with premise plumbing account for the largest number of legionellosis cases in the United States. So, while it is important to understand Legionella as such, it is also important to investigate how to treat drinking water in premise plumbing for Legionella and other waterborne pathogens. While there are currently several methods recognized as potential means of inactivating waterborne pathogens, several shortcomings continue to plague its implementation. These methods are generally of two types. Firstly, there are chemical treatments such as chlorine, chlorine dioxide, monochloramine, ozone, and copper-silver ionization. Secondly, there are physical treatments such as thermal inactivation and media filtration. Their shortcomings range from being labor-intensive and costly to having negative health effects if not properly operated. Recently developed technologies including ultraviolet (UV) irradiation using light emitting diodes (LEDs) and innovative carbon nanotube (CNT) filters can better control waterborne pathogens by allowing for the simultaneous use of different treatment measures in plumbing systems.

A criterion for analyzing the accuracy characteristics of applied satellite constellations (ASC) possible structures for observing targets in the Earth surface and/or near-surface layer is proposed. The criterion is not related to features of onboard hardware and depends on structure, parameters and dynamics of ASC. The criterion is based on consideration of determination accuracy of the objects geographical coordinates. An algorithm for numerical simulation of ASC is presented. Comparative accuracy estimates for various types of ASC are presented. Accuracy characteristics of Walker constellations and Near-Polar Satellite Constellations with various pattern types are considered. The main design-ballistic parameters that determine the accuracy of ASC and affect the cost of their creation are determined, and the nature of these parameters influence also shown.
Results can be used for initial decision of ASC pattern during preliminary design stage.

Multidimensional spline–interpolation–extrapolation methods for approximating hydraulics of steering actuating units for rocket stages
Authors: BELONOGOV Oleg B.
Published: March 2020

The paper discusses development principles of multidimensional approximation methods for hydraulic properties of throttling windows in slide hydraulic valves of electrohydraulic amplifiers of steering actuator, that are based on cubic spline-interpolation-extrapolation (SIE) of functions. A distinctive feature of the methods that were developed consists in that math simulations do not require complex analytical dependences of the properties, but rather only tabular representation of experimental data is used for their approximation in the course of calculation. The high efficiency of cubic SIE-based multidimensional approximation methods presented in the paper has been proven and demonstrated in math models for static analysis of autonomous one-stage electrohydraulic steering actuators with two- and four-throttle electrohydraulic amplifiers. Thanks to these methods the calculations of static properties of steering actuators within wide ranges of working fluid temperatures and power supply voltages are at present accurate to within ±2%.

Flow characteristics of systems for carbon dioxide scrubbing from the atmosphere in the pressurized volume of a space station
Authors: GUZENBERG Arkadiy S. , TELEGIN Alexandr A. , YURGIN Aleksey V.
Published: March 2020

Carbon dioxide (СО2) scrubbing from pressurized volumes of long-term space stations is one of the most critical aspects of crew life support, since each person, on average, releases 480 liters of СО2 (~ 1kg) per day. Meanwhile, СО2 is one of the gases required for human breathing, but at the same time its content in the atmosphere of the pressurized cabin must be kept below established standards, exceedance of which makes СО2 a contaminant harmful to humans. It should also be taken into account that at present the established standards for СО2 content in the space station atmosphere are not based on scientific research.
The key parameter of the scrubbing system, which determines the СО2 content in the atmosphere of the space station pressurized cabin, is the effective flow rate of the scrubbed air through the system. It was established that in order to scrub the atmosphere, two requirements must be met: 1) supply the required air flow rate to the scrubbing system (this requirement applies to all types of the system), 2) provide the required efficiency of the scrubbing system for the contaminant removal.
A formula has been derived for calculating the effective flow rate through the air scrubbing system, allowing not only to calculate the necessary charge through system of clearing, but also which makes it possible to compare performances of various types of systems. It was established that the most efficient system for scrubbing СО2 from the air is the sorption system, since it has the largest absorption surface, all other conditions being equal, and, therefore, it has the highest efficiency factor
Key words Space station, carbon dioxide, air scrubbing, standards for СО2 content, effective airflow rate, calculation formula, efficiency factor, absorption system for scrubbing СО2 from air.

The scientific equipment «Plasmakrystall–4» («PK–4») is designed to study complex (dusty) plasma under microgravity conditions aboard the International Space Station (ISS) and is a joint project of the European Space Agency (ESA) and Roscosmos. Scientific equipment «PK–4» is integrated into «European physiological modules» (EPM) rack, in the European laboratory module Columbus. Experiment control — automated, software-interactive, or manual from an on-board laptop and/or from a terminal in the ground control center. A low-pressure direct current discharge in noble gases in a glass tube is used to create a plasma at scientific equipment «PK–4». Microparticles of a given size are injected into the discharge to obtain a complex plasma. Two digital video cameras allow to trace individual microparticles inside the tube in phase space, which makes a complex plasma to be a good model for studying classical phenomena in condensed matter at the kinetic level. To monitor the plasma conditions, an integrated spectrometer and another video camera are used allowing to observe the plasma's own emission at different wavelengths. To study the reaction of microparticles to external forces, they can be exposed to radiation from a powerful laser, a gas stream, and also to thermophoretic force, i.e., by producing a given temperature gradient.

Static firing tests of oxygen-hydrogen propulsion units with propellant tank load of up to 2700 kg of hydrogen are run with special safety precautions and using emergency test protection system covering up to 60% of contingencies. Test on propulsion units with higher hydrogen propellant loads (up to 7000 kg) require additional safety measures, based on improved effectiveness of the fire and explosion prevention systems, emergency protection, and the coverage ratio for emergency (off-nominal) situations. The key factors for improving off-nominal situations coverage ratio during tests are research into systems for earlier detection of hydrogen leaks and the use of inhibitors with nitrogen as the phlegmatizing agent to prevent explosion of the hydrogen/air (oxygen) mixtures.
The paper presents results of studies into systems for early detection of hydrogen leaks and design of monitoring equipment based on fiber optics and microcavity structures that have higher speed of response, selectivity, immunity to noise and reliability.

Published: March 2020

Normally, the component composition of building materials makes a significant contribution when formation of final performance properties of them. Moreover, new types of binding systems, in spite of their poor knowledge, this effect on the structural characteristics of final composites also takes place. In this work, perlite-based geopolymer binder as an example, was studied.

In framework of the study, it was found that the application of grinding mill with a metal lining leads to the formation of Fe- milling yield, which is included into crushed raw materials (perlite) com-position.

It was established that the particles of the resulting Fe- component are nanoscaled.

The X-ray phase and chemical analyzes were used to determine the mechanism of the effect of the Fe- component on the properties of perlite-based geopolymer.

Microstructure of the hardened geopolymer paste were studied using SEM microscopy. Phase and mineral composition of geopolymer paste obtained by XRD-analysis showed, when the hardening process, nanosized iron hydroxide or bernalite Fe(OH)3(H2O)0.25 is formed in the geopolymer system, that is 5 times more than metallic iron. This is initiates the structure destruction and confirmed by the low values compressive strength of the geopolymer stone.

ANALYSIS OF THE RESULTS OF TENSOMETRIC STUDIES OF NATURAL BORED CONICAL PILES
Authors: Rybnikova I. , Rybnikov A.
Published: March 2020

Four bored piles of two standard sizes with a length of 4,5 m, a diameter of heads of 0,4 and 0,6 m, a diameter of the lower end of 0,2 m with a taper angle of 1o20ʹ and 2o40ʹ, respectively, are studied. Two different types of piles are equipped with a height of four strain gauges, and two-ten bulldozers of five on each of the diagonal opposite sides. The soils on the experimental ground are composed of solid sandy loam. According to the measurements of strain gauges and load cell, plots of the distribution of forces and stresses in sections along the pile trunk, as well as plots of contact stresses along their lateral surface are constructed. The results of the research revealed that additional forces of soil repulsion along the inclined lateral surface during its sedimentation under load are significantly involved in the bearing capacity of bored conical piles. The proportion of soil resistance, depending on the angle of taper, is 34-49 % of the total bearing capacity, the resistance of the lower end – 17-23 %, friction on the side surface of the trunk-34-43 %. These data indicate the effectiveness of giving the trunks of bored piles up to 5 m even a slight taper in the range of 1,5 o ... 3,0 o.

Published: March 2020

Background

Autosomal dominant polycystic kidney disease is caused by genetic mutations in PKD1 or PKD2. Macrophages and their associated inflammatory cytokines promote cyst progression; however, transcription factors within macrophages that control cytokine production and cystic disease are unknown.

Methods

In these studies, we used conditional Pkd1 mice to test the hypothesis that macrophage-localized interferon regulatory factor-5 (IRF5), a transcription factor associated with production of cyst-promoting cytokines (TNFα, IL-6), is required for accelerated cyst progression in a unilateral nephrectomy (1K) model. Analyses of quantitative real-time PCR (qRT-PCR) and flow-cytometry data 3 weeks post nephrectomy, a time point before the onset of severe cystogenesis, indicate an accumulation of inflammatory infiltrating and resident macrophages in 1K Pkd1 mice compared with controls. qRT-PCR data from FACS cells at this time demonstrate that macrophages from 1K Pkd1 mice have increased expression of Irf5 compared with controls. To determine the importance of macrophage-localized Irf5 in cyst progression, we injected scrambled or IRF5 antisense oligonucleotide (ASO) in 1K Pkd1 mice and analyzed the effect on macrophage numbers, cytokine production, and renal cystogenesis 6 weeks post nephrectomy.

Results

Analyses of qRT-PCR and IRF5 ASO treatmentsignificantly reduced macrophage numbers, Irf5 expression in resident—but not infiltrating—macrophages, and the severity of cystic disease. In addition, IRF5 ASO treatment in 1K Pkd1 mice reduced Il6 expression in resident macrophages, which was correlated with reduced STAT3 phosphorylation and downstream p-STAT3 target gene expression.

Conclusions

These data suggest that Irf5 promotes inflammatory cytokine production in resident macrophages resulting in accelerated cystogenesis.

La música de tradición oral en los tiempos de la world music. ¿Es posible una protección legal más allá del derecho de autor?
Authors: Olave Soler Sebastian
Published: March 2020

La propiedad intelectual, tal como ha sido definida por el derecho occidental, ha tendido a ignorar las especificidades y multiplicidades de la creación musical. Los mecanismos diseñados a partir de esta concepción, basados en la invariabilidad de los textos y en el aprovechamiento económico, han favorecido un sistema que permite el uso indiscriminado de expresiones comunitarias, en particular de las músicas de tradición oral. A través de las nociones de autenticidad y de propiedad artística, este artículo reflexiona sobre la necesidad de ampliar y adaptar el derecho de propiedad intelectual, en la búsqueda de mecanismos de protección para dichas músicas, que tengan en cuenta sus particularidades artísticas y sociales.

Authors: Da Silva Candemil Luciano
Published: March 2020

El presente artículo presenta un estudio sobre el proceso de enseñanza-aprendizaje musical del candomblé, una modalidad de religión afro-brasileña. En este contexto, la música ejerce función comunicativa, participa de todos los rituales, así como está íntimamente relacionada con elementos extramusicales, como la danza y la mitología de los orixás, las divinidades africanas. Con el fin de extrapolar los contenidos cotidianos, el objetivo fue investigar las actividades musicales de una cultura específica para fomentar una reflexión sobre las prácticas educativas contemporáneas. Antes de avanzar en el universo religioso del candomblé, fue considerado oportuno, revisar los conceptos de cultura y educación para ayudar a la comprensión de ese complejo sistema musical y cultural. Por lo tanto, contando con la experiencia de un intenso trabajo de campo, se realizó una revisión bibliográfica teniendo como soporte teórico autores de las áreas de la educación (Brandão, 2007; Machado, 2007); de la educación musical (Arroyo, 2000; Kleber, 2006;); de la etnomusicología (Blacking, 2007; Almeida y Pucci, 2011); así como obras específicas sobre cultura (Tylor, 1871; Santos, 2006) y sobre la música del candomblé (Prandi, 2005; Cardoso, 2006; Fonseca, 2002); sólo para citar algunos. Por lo tanto, mediante una visión global del ambiente cultural del candomblé, anhelamos hacer contribuciones a una educación musical contextualizada.

Artificial Intelligence versus Agape Love: Spirituality in a Posthuman Age
Authors: Peters Ted
Published: March 2020

As Artificial Intelligence researchers attempt to emulate human intelligence and transhumanists work toward superintelligence, philosophers and theologians confront a dilemma: we must either, on the one horn, (1) abandon the view that the defining feature of humanity is rationality and propose an account of spirituality that dissociates it from reason; or, on the other horn, (2) find a way to invalidate the growing faith in a posthuman future shaped by the enhancements of Intelligence Amplification (IA) or the progress of Artificial Intelligence (AI). I grasp both horns of the dilemma and offer three recommendations. First, it is love understood as agape, not rational intelligence, which tells us how to live a godly life. Love tells us how to be truly human. Second, the transhumanist vision of a posthuman superintelligence is not only unrealistic, it portends the kind of tragedy we expect from a false messiah. Third, if as a byproduct of AI and IA research combined with H+ zeal the wellbeing of the human species and our planet is enhanced, we should be grateful.
Transhumanism, Posthumanism, and the Catholic Church
Authors: Malapi‑Nelson Alcibiades
Published: March 2020

In this essay, I engage the foreseeable consequences for the future of humanity triggered by Emerging Technologies and their underpinning philosophy, transhumanism. The transhumanist stance is compared with the default view currently held in many academic institutions of higher education: posthumanism. It is maintained that the transhumanist view is less inimical to the fostering of human dignity than the posthuman one. After this is established, I suggest that the Catholic Church may find an ally in a transhumanist ethos in a two‑fold manner. On the one hand, by anchoring and promoting the defense of “the human” already present in transhumanism. On the other, rethinking the effectiveness of the delivery of sacraments in a humanity heavily altered by these technologies.
Berkeley, Expressivism, and Pragmatism
Authors: Szałek Piotr
Published: March 2020

There is a long‑standing dispute among scholars concerning Berkeley’s supposed commitment to an emotivist theory of meaning as the very first (and an early modern) instance of non‑cognitivism. According to this position, the domains of religious and moral language do not refer to facts about the world, but rather express the emotional attitudes of religious or moral language users. Some scholars involved in the dispute argue for taking Berkeley to be an emotivist (non‑cognitivist), while others hold that we should not do so. This paper puts forward an interpretation that lends support to the non‑cognitivist reading of his stance, but in expressivist rather than emotivist terms. It argues that the label “expressivism” does more justice to the textual evidence concerning his understanding of moral language, as what is distinctive where this philosopher is concerned is his interest in explaining the nature of our practice of employing moral language (i.e. how we come to formulate moral statements as expressions of our non‑referential attitudes, and the meta‑level considerations pertaining to morality associated with this), rather than whether morality is just a matter of our emotions or feelings (i.e. such first‑order considerations about morality as whether moral rightness and wrongness correspond merely to our emotional states).
Economic Models of Mongolia and Vietnam: Common and Distinctive Features
Authors: Nguyen Quoc Hunga , Lezhenina T. V.
Published: March 2020

New economic models began to develop in Mongolia and Vietnam after the collapse of the Union of Soviet Socialist Republics (USSR), when former Soviet republics formed the Commonwealth of Independent States (CIS). Further development after the USSR’s dissolution was especially difficult for Mongolia, which almost entirely relied on the economic aid from the USSR. The US and the International Monetary Fund (IMF) immediately took advantage of the crisis in Mongolia. They offered tranches to Mongolia under the condition of complete democratization of political power and establishment of market-based development institutions within the framework of a standby arrangement. Vietnam embarked on a course of destroying the socialist model in 1986, i.e. before the USSR’s collapse, and its transition to a market economy was peculiar, yet significantly different from Mongolia’s.

Aim. The presented study aims to examine the benefits and drawbacks of the economic models of Vietnam and Mongolia as well as their common and distinctive features.

Methods. The study uses general methods of analyzing the international experience of transforming economic models.

Results. The authors prove the efficiency of the current Mongolian and Vietnamese models in the context of global instability and crises. Emergence of new, highly efficient technological paradigms and absence of internal political protests in Mongolia and Vietnam ensure economic sustainability and high growth rate. Russia’s military aid to these countries also plays an important role.

Conclusions. After the collapse of the Soviet Union, Mongolia received substantial assistance from the United States and was able to maintain state independence and develop its economy under the market conditions of economic activity. Relying on cooperation with Russia and China, in the 21st century Mongolia engaged in the processes of integration in the Asia-Pacific region (APR). The Vietnamese model was forming during the country’s participation in the ASEAN free trade zone and cooperation with the developed economies of Japan, the Republic of Korea, and the United States. Unlike Mongolia, Vietnam retained full political leadership of the Communist party, the unity of its people, and support for the development of market economy. In confronting difficult challenges, Vietnam receives assistance from the Donor Club.

Published: March 2020

Tikslas. Ištirti ir įvertinti Lietuvos bendrojo ugdymo mokyklas lankančių mokyklinio amžiaus vaikų mitybos įpročius.
Tyrimo medžiaga ir metodai. Tyrimas vyko 2018 m. rugsėjo – gruodžio mėnesiais. Anketiniu apklausos būdu ištirti ir įvertinti 4623 bendrojo ugdymo mokyklas lankančių 1–12 klasių vaikų mitybos įpročiai. Apklausa anoniminė, tiriamųjų vardai ir pavardės nebuvo rašomos, analizuojami tik apibendrinti apklausos duomenys. Statistinė duomenų analizė atlikta naudojant SPSS programos 18.0 versiją. Rezultatų skirtumas laikytas reikšmingu, kai gautoji p reikšmė buvo mažesnė arba lygi 0,05.
Tyrimo rezultatai parodė, kad mažiau kaip pusė (41 proc.) mokyklinio amžiaus vaikų valgo 4–5 kartus per parą; tik du trečdaliai pusryčiauja kasdien ir kas antras valgo mokykloje karštus pietus. Nustatyta, kad daržovių vartojimo dažnumas yra beveik toks pat, kaip ir vaisių bei uogų – juos kasdien vartoja tik du trečdaliai vaikų. Daugelis (71,3 proc.) kasdien vartoja mėsą ir mėsos produktus, daugiau kaip pusė (65,8 proc.) – pieną ir pieno produktus, tačiau beveik tiek pat vaikų (64,9 proc.) žuvį ir žuvies produktus vartoja tik kelis kartus per mėnesį arba jų nevartoja. Kas penktas apklausos dalyvis (19,9 proc.) atsakė, kad kasdien vartoja bulvių, kukurūzų ir kitus traškučius, kitus riebaluose virtus, skrudintus ar spragintus gaminius, kai kurie – saldumynus (39,3 proc.), geria įvairius gazuotus ir (ar) saldžiuosius gėrimus (23,5 proc.). Energinių gėrimų vaikai beveik nevartoja (90,5 proc.) arba juos vartoja tik kelis kartus per mėnesį.
Jaunesni vaikai, palyginti su vyresniais, berniukai, palyginti su mergaitėmis, dažniau valgo 4 ir daugiau kartų per parą, dažniau pusryčiauja bei valgo karštus pietus mokykloje, dažniau vartoja pieną ir pieno produktus bei mėsą ir jos produktus. Jaunesni vaikai, palyginti su vyresniais, taip pat dažniau valgo daržoves (išskyrus bulves), vaisius ir uogas, žuvį ir jos produktus. Daržoves šiek tiek dažniau valgo mergaitės, negu berniukai, mieste, negu kaime gyvenantys vaikai. Miestų vaikai dažniau pusryčiauja ir vartoja pieną bei jo produktus; kaimų – dažniau valgo karštus pietus mokykloje, vartoja mėsą ir jos produktus.
Išvados. Ne visų mokyklinio amžiaus vaikų mitybos įpročiai atitinka sveikos mitybos rekomendacijas. Visi vaikai, nepriklausomai nuo amžiaus, per mažai vartoja sveikatai palankių maisto produktų – daržovių, vaisių, uogų, žuvies ir jos gaminių. Nemažai vaikų, dažniausiai 11-14 metų (5-8 klasės), vis dar vartoja sveikatai nepalankius maisto produktus – bulvių, kukurūzų ir kitus traškučius, kitus riebaluose virtus, skrudintus ar spragintus gaminius, saldumynus, geria įvairius gazuotus ir (ar) saldžiuosius gėrimus.
