Authors: Cao Zongyu , Lv Wanyou , Huang Yanhong , Shi Jianqi , Li Qin
Published: February 2020

With rapid technological advances in airborne control systems, it has become imperative to ensure the reliability, robustness, and adaptability of airborne software since failure of these software could result in catastrophic loss of property and life. DO-333 is a supplement to the DO-178C standard, which is dedicated to guiding the application of formal methods in the review and analysis of airborne software development processes. However, DO-333 lacks theoretical guidance on how to choose appropriate formal methods and tools to achieve verification objectives at each stage of the verification process, thereby limiting their practical application. This paper is intended to illustrate the formal methods and tools available in the verification process to lay down a general guide for the formal development and verification of airborne software. We utilized the Air Data Computer (ADC) software as the research object and applied different formal methods to verify software lifecycle artifacts. This example explains how to apply formal methods in practical applications and proves the effectiveness of formal methods in the verification of airborne software.
Comparing Individual Tree Height Information Derived from Field Surveys, LiDAR and UAV-DAP for High-Value Timber Species in Northern Japan
Authors: Moe Kyaw , Owari Toshiaki , Furuya Naoyuki , Hiroshima Takuya
Published: February 2020

High-value timber species such as monarch birch (Betula maximowicziana Regel), castor aralia (Kalopanax septemlobus (Thunb.) Koidz), and Japanese oak (Quercus crispula Blume) play important ecological and economic roles in forest management in the cool temperate mixed forests in northern Japan. The accurate measurement of their tree height is necessary for both practical management and scientific reasons such as estimation of biomass and site index. In this study, we investigated the similarity of individual tree heights derived from conventional field survey, digital aerial photographs derived from unmanned aerial vehicle (UAV-DAP) data and light detection and ranging (LiDAR) data. We aimed to assess the applicability of UAV-DAP in obtaining individual tree height information for large-sized high-value broadleaf species. The spatial position, tree height, and diameter at breast height (DBH) were measured in the field for 178 trees of high-value broadleaf species. In addition, we manually derived individual tree height information from UAV-DAP and LiDAR data with the aid of spatial position data and high resolution orthophotographs. Tree heights from three different sources were cross-compared statistically through paired sample t-test, correlation coefficient, and height-diameter model. We found that UAV-DAP derived tree heights were highly correlated with LiDAR tree height and field measured tree height. The performance of individual tree height measurement using traditional field survey is likely to be influenced by individual species. Overall mean height difference between LiDAR and UAV-DAP derived tree height indicates that UAV-DAP could underestimate individual tree height for target high-value timber species. The height-diameter models revealed that tree height derived from LiDAR and UAV-DAP could be better explained by DBH with lower prediction errors than field measured tree height. We confirmed the applicability of UAV-DAP data for obtaining the individual tree height of large-size high-value broadleaf species with comparable accuracy to LiDAR and field survey. The result of this study will be useful for the species-specific forest management of economically high-value timber species.
Latent Structure Matching for Knowledge Transfer in Reinforcement Learning
Authors: Zhou Yi , Yang Fenglei
Published: February 2020

Reinforcement learning algorithms usually require a large number of empirical samples and give rise to a slow convergence in practical applications. One solution is to introduce transfer learning: Knowledge from well-learned source tasks can be reused to reduce sample request and accelerate the learning of target tasks. However, if an unmatched source task is selected, it will slow down or even disrupt the learning procedure. Therefore, it is very important for knowledge transfer to select appropriate source tasks that have a high degree of matching with target tasks. In this paper, a novel task matching algorithm is proposed to derive the latent structures of value functions of tasks, and align the structures for similarity estimation. Through the latent structure matching, the highly-matched source tasks are selected effectively, from which knowledge is then transferred to give action advice, and improve exploration strategies of the target tasks. Experiments are conducted on the simulated navigation environment and the mountain car environment. The results illustrate the significant performance gain of the improved exploration strategy, compared with traditional ϵ -greedy exploration strategy. A theoretical proof is also given to verify the improvement of the exploration strategy based on latent structure matching.

‘I see where I stand’ Detachment and Engagement in Harry Clifton’s Poetry
Authors: Keatinge Benjamin
Published: February 2020

This essay reads Harry Clifton’s poetry as a body of work that illustrates the poet’s engagement with and detachment from the poetry of his peers. It notes Clifton’s chosen routes of travel in Africa, Asia, and Europe, his interest in Ireland and its elsewheres and his endeavours to find an ideal distance to write from. It also elucidates his Irish subject matter, his involvement with journals, editors and publishers as well as his critical readings of 20th-century Irish poetry. The essay engages with important strands of current critical thinking that have sought to examine a post-nationalist Ireland with Clifton being seen as a bridge between an older and younger circle of writers. Neither hermetic nor sociable, Clifton emerges as a poet engaging with concentric circles of Irish poetry on his own terms.
The Open Constructed Public Sphere: Aeschylus’ The Suppliant Women in a Version by David Greig
Authors: Rodríguez Verónica
Published: February 2020

This article looks at the ‘public’ ‘place’ of drama in Britain at present by offering an analysis of a contemporary version of an ancient Greek play by Aeschylus, entitled The Suppliant Women, written by David Greig, directed by Ramin Gray, and first performed at the Royal Lyceum Theatre Edinburgh in 2016. Following an agonistic (Chantal Mouffe), rather than a consensual (Jürgen Habermas) model of the public sphere, it argues that under globalisation, three cumulative and interwoven senses of the public sphere, the discursive, the spatial, and the individual and his/her/their relation to a larger form of organisation, despite persisting hegemonic structures that perpetuate their containment, have become undone. This is the kind of unbounded model of public sphere Greig’s version of Aeschylus’ The Suppliant Women seems to suggest by precisely offering undoings of discourses, spaces, and individualisations. In order to frame the first kind of undoing, that is, the unmarking of theatre as contained, the article uses Christopher Balme’s notion of ‘open theatrical public sphere’, and in order to frame the second, that is, the undoing of elements ‘in’ Greig’s version, the article utilises Greig’s concept of ‘constructed space’. The article arrives then at the notion of the open constructed public sphere in relation to The Suppliant Women. By engaging with this porous model of the public sphere, The Suppliant Women enacts a protest against exclusionary, reductive models of exchange and organisation, political engagement, and belonging under globalisation.
Reliability of a New Test of Balance Function in Healthy and Concussion Populations
Authors: Kis Mihaly
Published: February 2020

Providing quantitative measures of balance and posture is a valuable aid in clinical assessment and in recent years several devices have been introduced that have demonstrated the accurate measure of balance via deviation of center of mass utilizing software algorithms and mobile devices. The purpose of this study was to assess the accuracy of EQ Balance against the SwayTM Balance System (Sway), another balance device that is currently established as an accurate measure of balance, and to evaluate the test–retest reliability of EQ Balance. Seventy individuals presenting to a sports medicine and concussion clinic volunteered to participate in the assessment of balance utilizing Sway and EQ Balance simultaneously. The group included 25 males and 45 females (mean age: 37.8 ± 14.8, range: 13–65) with and without concussion or other neurological conditions (39 concussed vs. 31 non-neurologically injured, or healthy). Twenty-six of the concussed participants were balance-impaired. Participants performed five postures while holding the mobile device against their chest. Participants held a device holder that secured two devices: one iPhone 6 with EQ Balance and a second iPhone 6 with Sway Balance. The average balance score on all five stances was recorded as the “average balance score”. Average balance scores were in statistical agreement between the two methods across the entire group, and for sub-groups according to the Deming regression (p < 0.01). The intra-class correlation (ICC) for the cohort was 0.87 (p < 0.001). Across the cohort, EQ Balance measured significantly worse balance scores in the balance-impaired group, comprised of participants with brain injury who failed a clinical balance screening test, compared to the group without clinically-determined balance impairment (this group includes healthy and some concussed patients). EQ Balance demonstrated safety, as it was considered safe to perform independently (i.e., without an observer) in those with impaired balance, and high test- retest reliability in the healthy and concussed patient population. Statistical agreement was established between the two measures of EQ Balance and Sway Balance for the average balance score across all five stances. The ICC analysis demonstrates strong consistency of the task output between test sessions. Given these results, EQ Balance demonstrates strength as a new balance assessment tool to accurately measure balance performance as part of a unique and novel gamified application in healthy and neurologically injured populations.

Published: February 2020

To promote the development of nuclear power project in inland China, a specialized multi-criteria decision support framework is constructed for the site selection of inland nuclear power plants in this work. The best worst method (BWM), decision-making trial and evaluation laboratory (DEMATEL), and technique for order performance by similarity to ideal solution (TOPSIS) are integrated with Z-numbers, namely Z-BWM, Z-DEMATEL, and Z-TOPSIS. Z-BWM and Z-DEMATEL are combined to produce the weights of criteria, and an extended Z-TOPSIS is utilized to determine the ranking of all alternatives. Finally, a case study is performed in Hunan province to demonstrate the practicability of the proposed decision support framework. The robustness and feasibility of the proposed method are shown by an in-depth analysis of the decision results.

The aim is to put new light on the single ladder problem (SLP). Some new methods for finding complete integer solutions to the corresponding quartic equation z 4 − 2 L z 3 + ( L 2 − a 2 − b 2 ) z 2 + 2 L a 2 z − L 2 a 2 = 0 are developed. For the case L ≥ L min , these methods imply a complete parametric representation for integer solutions of SLP in the first quadrant. Some corresponding (less complete) results for the case L > L min are also pointed out.

Published: February 2020

Background and objectives: Laryngeal squamous cell carcinoma (LSCC) is one of the most common head and neck tumors. The molecular mechanism of LSCC remains unclear. The aim of this study was to evaluate the prevalence of Human papillomavirus (HPV) and single nucleotide polymorphisms (SNPs) of TP53, MDM2, MDM4, MTHFR, CASP8, and CCR5 genes in LSCC, and to assess their correlations with patient survival. Materials and Methods: 49 LSCC patients were enrolled in this study. PCR and qRT-PCR were used to detect, identify, and quantify HPV. SNPs were genotyped using PCR and PCR-RFLP. Results: By analyzing the interactions of the SNPs of the genes with clinical parameters, the majority of patients with lymph node status (N1,2) were identified as carriers of MDM2 T/G, CASP8 ins/del, CCR5 wt/wt SNP. Cluster analysis showed that patients with MDM2 T/T SNP survive longer than patients identified as CASP8 ins/ins, MTHFR C/C, and MDM4 A/A variant carriers; meanwhile, LSCC patients with MDM2 T/T polymorphic variant had the best survival. Multivariate analysis showed that HPV-positive patients without metastasis in regional lymph nodes (N0) and harboring CASP8 ins/del variant had the best survival. Meanwhile, HPV-negative patients with identified metastasis in lymph nodes (N1 and N2) and CASP8 ins/del variant had poor survival. Conclusions: This finding suggests patients survival prognosis and tumor behavior are different according HPV status, SNP variants, and clinical characteristics of the LSCC.
Research on Parameter Optimization of Micro-Milling Al7075 Based on Edge-Size-Effect
Authors: Chen Yinghua , Wang Tao , Zhang Guoqing
Published: February 2020

In the process of micro-milling, the appearance of the edge-size-effect of micro-milling tools cannot be ignored when the cutting parameters are smaller than the cutting edge arc radius (r0) of the micro-milling tool or close to it, and it could easily lead to low cutting efficiency and poor surface quality of the micro-slot. Through micro-milling experiments on Al7075-T6 materials, the change of milling force in the plough zone and shear zone during micro-milling was studied, and the minimum cutting thickness (hmin) range was determined to be 0.2r0–0.4r0 based on r0 of the micro-milling tool. Subsequently, the effect of fz/r0 (fz denotes feed rate per tooth) on the top burr formation of the micro-slot, the surface roughness (Ra) of the micro-slot bottom, and the milling force was studied, and a size-effect band of micro milling was established to determine the strong size-effect zone, transition size-effect zone, and the weak size-effect zone. Finally, two different fz/r0 in the strong size-effect zone and the weak size-effect zone are compared, which proves that the main purpose of the cutting parameters optimization of micro-milling is to avoid cutting parameters locating in the strong edge-size-effect zone. The above conclusions provide a theoretical basis for the selection of micro-milling cutting parameters, and an important reference in improving the surface quality of micro-milling.

The current drug development pipeline takes approximately fifteen years and $2.6 billion to get a new drug to market. Typically, drugs are tested on two-dimensional (2D) cell cultures and animal models to estimate their efficacy before reaching human trials. However, these models are often not representative of the human body. The 2D culture changes the morphology and physiology of cells, and animal models often have a vastly different anatomy and physiology than humans. The use of bioengineered human cell-based organoids may increase the probability of success during human trials by providing human-specific preclinical data. They could also be deployed for personalized medicine diagnostics to optimize therapies in diseases such as cancer. However, one limitation in employing organoids in drug screening has been the difficulty in creating large numbers of homogeneous organoids in form factors compatible with high-throughput screening (e.g., 96- and 384-well plates). Bioprinting can be used to scale up deposition of such organoids and tissue constructs. Unfortunately, it has been challenging to 3D print hydrogel bioinks into small-sized wells due to well–bioink interactions that can result in bioinks spreading out and wetting the well surface instead of maintaining a spherical form. Here, we demonstrate an immersion printing technique to bioprint tissue organoids in 96-well plates to increase the throughput of 3D drug screening. A hydrogel bioink comprised of hyaluronic acid and collagen is bioprinted into a viscous gelatin bath, which blocks the bioink from interacting with the well walls and provides support to maintain a spherical form. This method was validated using several cancerous cell lines, and then applied to patient-derived glioblastoma (GBM) and sarcoma biospecimens for drug screening.

Authors: Souza Barbosa Thiago , Vilela Brum Igor , José Martins Alves Márcio , Bustamante Teixeira Maria Teresa
Published: February 2020

Introdução: As doenças do aparelho circulatório (DAC) são responsáveis por 30% das mortes no Brasil, além de gerar incapacidades ealtos custos.  Apesar disso, pouco se sabe sobre a relação entre a mortalidade por DAC e as condições de vida e assistência à saúde nos municípios brasileiros, especialmente em contextos regionais. Objetivo: investigar a associação de variáveis de saúde e sociodemográficas com a mortalidade por DAC em Minas Gerais (MG). Método: estudo ecológico a partir de dados secundários,tendo como unidade de análise 418 municípios de MG. A variável dependente foi a taxa de mortalidade por DAC e as variáveis de desfecho foram 32 indicadores de serviços de saúde e 22 indicadores demográficos e socioeconômicos. Realizou-se a análise bivariada dos dados através do coeficiente de correlação de Pearson, seguida da análise fatorial e, por fim, da regressão linear múltipla. Resultados: As DAC ocasionaram 30,9% da mortalidade total nos municípios analisados, observando-se associação positiva com número deconsultórios de clínica básica, população urbana e internações por DAC no SUS; e negativa comvalor médio por internaçãoe despesa total com profissionais da saúde. Conclusão: frente ao elevado número de municípios com pequena estrutura assistencial em MG, as ações de promoção à saúde e prevençãoparecem ser as mais adequadas visando a redução dastaxas de mortalidade por DAC. Também com esse objetivo, os casos mais graves e as complicações devem ser manejados em centros de referência, contando com recursos materiais e profissionais adequados.

Published: February 2020

A religiosidade/espiritualidade (R/E) é um tema de grande interesse na atualidade, principalmente no que concerne à sua relação com a saúde mental. De fato, o efeito benéfico dessa associação tem sido descrito com níveis de bem-estar maiores, redução do uso de drogas, menores taxas de depressão e ansiedade, além de se apresentar como um fator protetor ao comportamento suicida (CS). Contudo, os mecanismos que possam explicar esses resultados ainda não foram adequadamente esclarecidos. Da mesma forma, existem muitas dificuldades em transpor esse conhecimento para a prática clínica, sendo este um dos maiores desafios deste campo de pesquisa. Assim, diante da relevância deste tópico, este artigo objetiva fazer uma atualização sobre as conexões entre R/E e CS, visando discutir não só os aspectos positivos, mas também os possíveis elementos negativos envolvidos nessa relação. Para tal, foi realizada uma revisão da literatura com ênfase em artigos publicados nas últimas duas décadas.
A Hybrid Approach for Providing Improved Link Connectivity in SDN
Authors: Vanamoorthy Muthumanikandan , Chinnaiah Valliyammai , Sekar Harish
Published: February 2020

Software-Defined Networking (SDN) is a unique approach to design and build networks. The networks services can be better handled by administrators with the abstraction that SDN provides. The problem of re-routing the packets with minimum overhead in case of link failure is handled in this work. Protection and restoration schemes have been used in the past to handle such issues by giving more priority to minimal response time or controller overhead based on the use case. A hybrid scheme has been proposed with per-link Bidirectional forwarding mechanism to handle the failover. The proposed method makes sure that the controller overhead does not impact the flow of packets, thereby decreasing the overall response time, even with guaranteed network resiliency. The computation of the next shortest backup path also guarantees that the subsequent routing of packets always chooses the shortest path available. The proposed method is compared with the traditional approaches and proven by results to perform better with minimal response time.
On 2-Colorability Problem for Hypergraphs with P_8-free Incidence Graphs
Authors: Quaddoura Ruzayn
Published: February 2020

A 2-coloring of a hypergraph is a mapping from its vertex set to a set of two colors such that no edge is monochromatic. The hypergraph 2- Coloring Problem is the question whether a given hypergraph is 2-colorable. It is known that deciding the 2-colorability of hypergraphs is NP-complete even for hypergraphs whose hyperedges have size at most 3. In this paper, we present a polynomial time algorithm for deciding if a hypergraph, whose incidence graph is P_8-free and has a dominating set isomorphic to C_8, is 2-colorable or not. This algorithm is semi generalization of the 2-colorability algorithm for hypergraph, whose incidence graph is P_7-free presented by Camby and Schaudt.
Enhanced Median Flow Tracker Based on Photometric Correction for Videos with Abrupt Changing Illumination
Authors: Narayana Asha , Venkata Narasimhadhan
Published: February 2020

Object tracking is a fundamental task in video surveillance, human-computer interaction and activity analysis. One of the common challenges in visual object tracking is illumination variation. A large number of methods for tracking have been proposed over the recent years, and median flow tracker is one of them which can handle various challenges. Median flow tracker is designed to track an object using Lucas-Kanade optical flow method which is sensitive to illumination variation, hence fails when sudden illumination changes occur between the frames. In this paper, we propose an enhanced median flow tracker to achieve an illumination invariance to abruptly varying lighting conditions. In this approach, illumination variation is compensated by modifying the Discrete Cosine Transform (DCT) coefficients of an image in the logarithmic domain. The illumination variations are mainly reflected in the low-frequency coefficients of an image. Therefore, a fixed number of DCT coefficients are ignored. Moreover, the Discrete Cosine (DC) coefficient is maintained almost constant all through the video based on entropy difference to minimize the sudden variations of lighting impacts. In addition, each video frame is enhanced by employing pixel transformation technique that improves the contrast of dull images based on probability distribution of pixels. The proposed scheme can effectively handle the gradual and abrupt changes in the illumination of the object. The experiments are conducted on fast-changing illumination videos, and results show that the proposed method improves median flow tracker with outperforming accuracy compared to the state-of-the-art trackers

The Lake Onegо Ecosystem: Aquatic Communities Response to Anthropogenic Factors and Climate Change
Authors:   Kalinkina N.M., Tekanova Y.V., Syarki M.T.
Published: February 2020

Original and take from the references data on the Lake Onegо anthropogenic load dynamics, plankton and benthos conditions over the period of the previous 55 years have been analyzed in order to assess the ecosystem response to long-term and new impact factors such as climate change, chemical and biological contamination. It has been demonstrated that the lake pollution is of a local character while more than 90% of its water area maintains the initial oligotrophic status. Biogenic matter transported to the lake with the pulp-and-paper mills and domestic waste water caused euthrophication of two North-Western bays. The load caused by point pollution sources decreased over the past decades; this was proved by the reoligotrophication processes that occurred in the euthrophic bays bottom communities. However, diffuse pollution sources appeared. Trout-breeding farms in the North-Western bays are a potential threat of the lake euthrophication. A chronic oil pollution of the lake Petrozavodsk Guba has been revealed, for the time being the lake ecosystem manages to cope with it. Biological contamination associated with immigration of Gmelinoides fasciatus Stebbing Baikal amphipoda has led to the increase of the intertidal zone certain parts’ productivity increase and improving of the perch young nutritive base. Climate change causes reversible deviations in the plankton communities’ structure and season recurrence. In order to maintain economic value of the water body it is recommended to adopt some legislative measures for protection of the Lake Onegо as a strategic source of fresh water and to develop the scientifically-based ecological monitoring criteria with taking into account its heterogeneity.
Many-year dynamics of humic substances content in the drained high bog waters in Western Siberia
Authors:   Kharanzhevskaya Y.A., Ivanova Y.S., Voistinova Y.S.
Published: February 2020

Analysis of the many-year dynamics of the humic substances content in forest/melioration site bog waters has been presented. Spectral, correlation and factor analysis have been carried out. The investigations have shown a 2-4 years cyclic recurrence in high drained bog waters humic substances content, as well as statistically significant trend to the humic acids concentration decrease over the many-year period. As for the seasonal dynamics, an appropriate increase of humic acids content in bog waters has been detected in the middle of the vegetation period (July-August). Correlation analysis enabled to state a relationship between the humic acids quantity and the peat reserve redox potential. In some years connections between the humic substances amount in water with the bog water level, peat humidity, peat deposit temperature, air temperature, and atmospheric precipitation were recorded. At that, the temperature regime was a limiting factor determining the humic acids quantity in bog waters, while the peat deposit moisture load determined fulvoacids quantity. It has been shown that as a result of a high bog drainage the increase of vegetative remains and peat organic matter transformation intensity and increase of humic substances in bog waters (14% increase of humic acids and 18% increase of fulvoacids) in comparison with the region background high bogs has occurred. Therefore, economic use of peat bogs, air temperature and atmospheric precipitation increase associated with climate change will facilitate the increase of organic matter both in bog waters and, probably, in groundwaters and river waters of the region.

Issues of forecasting of construction works on floodplains impact on hydrological and bed processes at adjacent ranges of major rivers have been considered. Mathematical models of flows and bed processes at the river ranges with complicated morphometry of the bed and floodplain have proposed. Their application enables to solve a significant scientific/practical problem of assessment of the construction works impact on flooding floodplain territories and the Ob River bed erosion in the vicinity of the city of Barnaul. Calculations for the Ob River range under consideration have been done according a computer hydrodynamic model produced with the use of hydrological data, outcomes of bed surveying and geodesic investigations. The planning construction work impact on the water levels, flow velocities and the river bed erosion in case of different Ob River flows has been shown. The bed and hydrological processes impact on the site of the designed facility has been assessed.

Published: February 2020

The outcomes of hydro/chemical and soil 1800 km long surveying of the Volga River from Kazan to Astrakhan have been analyzed. Conjugated analysis of the organic (petroleum products, phenols, and pesticides) and non-organic (metals – Cd, Co, Pb, Ni, Zn, Cr, Mn, Fe, Al) pollutants and their proportion in the Middle and Lower Volga (Kuibyshev, Saratov and Volgograd reservoirs) and unregulated part of downstream water and bottom sediments has been carried out. To test a hypothesis on the system interaction of different types of pollutants content distribution in water and bottom sediments their spatially determined comparative assessment has been applied for the first time. Three main types of the pollutants distribution within the“water-bottom sediments” system have been singled out: depositing, transit, and active/passive self-purification types. The “transit” type of metals distribution is typical for Kuibyshev reservoir. It is characterized by the higher metals concentration in water and the absence of their content increase in bottom sediments. Zones of self-purification from metal compounds have been found in water areas of Saratov and Volgograd reservoirs, while depositing zones are typical for the Volga downstream where metals accumulation in sediments have been found. A considerable portion of pesticides and petroleum products supplied to the Volga reservoirs’ ecosystems is accumulated by bottom sediments. The most part of the Middle and Lower Volga water area is a zone of active selfpurification in terms of phenol compounds. It has been shown that when the Volga environmental conditions is assessed the indicators of copper, nickel, as well as iron, manganese, cadmium and petroleum products in bottom sediments are the most informative.

Aeration impact on aerosols discharge from aeration tanks in the process of domestic waste water treatment has been considered. Waste waters and their aerosols microbial pollution has been shown. New regularities of the temperature, time, and wind velocity on moisture discharge and microbial pollution in the form of aerosols from water surface of the biological treatment aerated facilities have been obtained. The equations that enable to calculate moisture emission from water surface in the process of aeration are presented. Water losses in the form of aerosols in the process of aeration depending on the outside air temperature and wind velocity were determined theoretically and experimentally. The microorganisms specific discharge from an aeration tank equal to 2.144 г/(m2∙s) in terms of coliform species was calculated. The microbial pollution maximal concentration values for various meteorological conditions were determined for performance of standard calculations of microbial discharges with aerosols from aeration tanks. The obtained equations can be used in designing of engineering measures aimed at reduction of the discharged aerosols negative microbial impact on water bodies adjacent to the territories of domestic waste waters biological treatment facilities.

Results of analysis of 222Rn in 18 springs and 23 wells (sources of drinking water) of Ekaterinburg and Sverdlovsk Oblast are presented. According to the outcomes of the samples analysis, in seven springs (39 %) and seven wells (30 %) excess of the radon interference level was found, at this radon maximal activity in water reached 1350 Bk/l. The radon disposal methods for groundwater with the excess of radon interference level have been proposed. It has been shown that out of physical radon disposal methods air barbotage through water is the most effective (more that 99% ), while settling is the least effective. Good results were produced by the radon absorption on active carbon: with the use of Carbotech (Germany) active carbon it is possible to dispose more that 90 % of radon. This method advantage is the absence of internal irradiation due to the radon transition to the air surface layer. As for the scientific aspect, the regularities of the radon extraction degree depending on such factors as water settling time, temperature, air barbotage time, active carbon type, water filtering through active carbon velocity have been obtained. These outcomes are of practical interest in terms of radiation security provision for population when using groundwater sources for drinking water supply.

A Constituição Federal de 1988 não garantiu que as políticas de esporte e de lazer compusessem o rol de competências dos municípios. Nesse sentido, há de perspectivar a inação como um comportamento possível dos gestores municipais no que tange ao financiamento do esporte e do lazer. Nesse sentido, o presente estudo de natureza descritivo exploratório buscou analisar o comportamento das prefeituras do estado do Mato Grosso no que concerne ao financiamento do esporte e do lazer na Função Desporto e Lazer (FDL), e apresenta, como objetivos específicos analisar qual a participação dos municípios no estado do Mato Grosso no financiamento da FDL e analisar o financiamento da FDL por níveis da classe populacional e desenvolvimento humano. Os resultados indicam que as prefeituras do estado do Mato Grosso, no ciclo eleitoral 2005/08, preferem o investimento da FDL a inação.

Analisamos o processo de apropriação e consolidação do espaço de lazer e cultura “Zumbi dos Palmares”, localizado em Teresina, capital do estado do Piauí. Destacamos e analisamos conflitos, lutas e movimentos realizados com o intuito de se apropriar deste espaço, antes de natureza escolar, hoje destinado a atividades de lazer, particularmente de diversas manifestações da cultura negra (coral em yorubá, oficinas de capoeira, percussão, dança, festas temáticas, cinema, biblioteca, exposições, etc). Atualmente a apropriação e consolidação deste espaço exerce um importante papel na difusão e valorização desta cultura no Piauí. A pesquisa foi realizada sob uma perspectiva qualitativa descritiva, tendo sido utilizada a entrevista semiestruturada como principal técnica de coleta de dados.

Este trabalho visa apresentar a “animação sociocultural” como aprimoramento da formação do profissional de Educação Física. Assim, este estudo de natureza qualitativa tem por objetivo aprofundar teoricamente sua concepção, com a finalidade de ampliar o leque de possibilidades de ação e atuação no mercado de trabalho para profissionais de Educação Física no Brasil. A metodologia utilizada foi uma revisão de literatura a partir da base de dados Parthenon/UNESP. Os resultados apontam diferentes perspectivas sobre a “animação sociocultural”, como a polissemia de conceitos existentes no Brasil, as ações pontuais, a atuação voltada à transformação social, o perfil profissional, a formação e o mercado de trabalho. Como considerações finais esta formação profissional desenvolve sujeitos transformadores, capazes de significar e/ou ressignificar a realidade e, desse modo, permitir o desenvolvimento do ser humano.

O objetivo do estudo foi compreender quais as características do lazer da população soteropolitana, tendo como lócus de análise os bairros “Barra” e “Massaranduba”. Para escolha das regiões levamos em consideração a divisão socioespacial, o perfil socioeconômico e outros aspectos. Para a coleta de dados, aplicamos um questionário semiestruturado a 43 pessoas com idade entre 20 e 79 anos. O método de análise esteve associado à proposta de Bardin (2002) que divide o conteúdo por categoria, para posterior reagrupamento analítico. Identificamos, portanto, que os soteropolitanos apresentam como locais de preferência para a fruição do lazer, a praia e o shopping e/ou cinema, o bar e/ou restaurante e o lar. Consideram ainda a “insegurança” fator crucial para uma possível mudança na escolha do programa de lazer, exigem mudanças efetivas e questionam sobre a possibilidade dos resultados da pesquisa atingirem a realidade social.

Published: February 2020

A pesquisa objetivou investigar teorias e conceitos de lazer desenvolvidos em cursos de Educação Física de instituições de ensino superior do estado de Sergipe. A pesquisa é apresentada no artigo em três seções: a primeira traz uma síntese de questões significativas referentes ao currículo; a segunda, uma oposição relevante para a compreensão das orientações filosófico-pedagógicas no campo do lazer; a terceira destinou-se à análise textual qualitativa dos dados empíricos coletados na pesquisa. O corpus foi composto por programas de Educação Física de instituições de ensino superior no estado de Sergipe que desenvolvem o componente curricular “lazer”, além de entrevistas com professores e alunos envolvidos nessas disciplinas. A análise mostra que há evidência das abordagens fenomenológica (uma disciplina) e positivista (duas disciplinas), tanto na forma (predominante) em que as disciplinas são desenvolvidas (métodos), como na própria conceituação do lazer (conteúdo).
