An Improved Deep Mutual-Attention Learning Model for Person Re-Identification
Authors: Jamal Miftah Bedru , Zhengang Jiang , Ming Fang
Published: March 2020

Person re-identification is the task of matching pedestrian images across a network of non-overlapping camera views. It poses aggregated challenges resulted from random human pose, clutter from the background, illumination variations, and other factors. There has been a vast number of studies in recent years with promising success. However, key challenges have not been adequately addressed and continue to result in sub-optimal performance. Attention-based person re-identification gains more popularity in identifying discriminatory features from person images. Its potential in terms of extracting features common to a pair of person images across the feature extraction pipeline has not been be fully exploited. In this paper, we propose a novel attention-based Siamese network driven by a mutual-attention module decomposed into spatial and channel components. The proposed mutual-attention module not only leads feature extraction to the discriminative part of individual images, but also fuses mutual features symmetrically across pairs of person images to get informative regions common to both input images. Our model simultaneously learns feature embedding for discriminative cues and the similarity measure. The proposed model is optimized with multi-task loss, namely classification and verification loss. It is further optimized by a learnable mutual-attention module to facilitate an efficient and adaptive learning. The proposed model is thoroughly evaluated on extensively used large-scale datasets, Market-1501 and Duke-MTMC-ReID. Our experimental results show competitive results with the state-of-the-art works and the effectiveness of the mutual-attention module.

Published: March 2020

In order to save people’s shopping time and reduce labor cost of supermarket operations, this paper proposes to design a supermarket service robot based on deep convolutional neural networks (DCNNs). Firstly, according to the shopping environment and needs of supermarket, the hardware and software structure of supermarket service robot is designed. The robot uses a robot operating system (ROS) middleware on Raspberry PI as a control kernel to implement wireless communication with customers and staff. So as to move flexibly, the omnidirectional wheels symmetrically installed under the robot chassis are adopted for tracking. The robot uses an infrared detection module to detect whether there are commodities in the warehouse or shelves or not, thereby grasping and placing commodities accurately. Secondly, the recently-developed single shot multibox detector (SSD), as a typical DCNN model, is employed to detect and identify objects. Finally, in order to verify robot performance, a supermarket environment is designed to simulate real-world scenario for experiments. Experimental results show that the designed supermarket service robot can automatically complete the procurement and replenishment of commodities well and present promising performance on commodity detection and recognition tasks.

Published: March 2020

T-spherical fuzzy set is a recently developed model that copes with imprecise and uncertain events of real-life with the help of four functions having no restrictions. This article’s aim is to define some improved algebraic operations for T-SFSs known as Einstein sum, Einstein product and Einstein scalar multiplication based on Einstein t-norms and t-conorms. Then some geometric and averaging aggregation operators have been established based on defined Einstein operations. The validity of the defined aggregation operators has been investigated thoroughly. The multi-attribute decision-making method is described in the environment of T-SFSs and is supported by a comprehensive numerical example using the proposed Einstein aggregation tools. As consequences of the defined aggregation operators, the same concept of Einstein aggregation operators has been proposed for q-rung orthopair fuzzy sets, spherical fuzzy sets, Pythagorean fuzzy sets, picture fuzzy sets, and intuitionistic fuzzy sets. To signify the importance of proposed operators, a comparative analysis of proposed and existing studies is developed, and the results are analyzed numerically. The advantages of the proposed study are demonstrated numerically over the existing literature with the help of examples.

Authors: Arce-López Beatriz , Lizarraga Elena , Vettorazzi Ariane , González-Peñas Elena
Published: March 2020

This manuscript reviews the state-of-the-art regarding human biological monitoring (HBM) of mycotoxins in plasma, serum and blood samples. After a comprehensive and systematic literature review, with a focus on the last five years, several aspects were analyzed and summarized: (a) the biomarkers analyzed and their encountered levels, (b) the analytical methodologies developed and (c) the relationship between biomarker levels and some illnesses. In the literature reviewed, aflatoxin B1-lysine (AFB1-lys) and ochratoxin A (OTA) in plasma and serum were the most widely studied mycotoxin biomarkers for HBM. Regarding analytical methodologies, a clear increase in the development of methods for the simultaneous determination of multiple mycotoxins has been observed. For this purpose, the use of liquid chromatography (LC) methodologies, especially when coupled with tandem mass spectrometry (MS/MS) or high resolution mass spectrometry (HRMS) has grown. A high percentage of the samples analyzed for OTA or aflatoxin B1 (mostly as AFB1-lys) in the reviewed papers were positive, demonstrating human exposure to mycotoxins. This review confirms the importance of mycotoxin human biomonitoring and highlights the important challenges that should be faced, such as the inclusion of other mycotoxins in HBM programs, the need to increase knowledge of mycotoxin metabolism and toxicokinetics, and the need for reference materials and new methodologies for treating samples. In addition, guidelines are required for analytical method validation, as well as equations to establish the relationship between human fluid levels and mycotoxin intake.

Published: March 2020

The study of fungal species evolved radically with the development of molecular techniques and produced new evidence to understand specific fungal mechanisms such as the production of toxic secondary metabolites. Taking advantage of these technologies to improve food safety, the molecular study of toxinogenic species can help elucidate the mechanisms underlying toxin production and enable the development of new effective strategies to control fungal toxicity. Numerous studies have been made on genes involved in aflatoxin B1 (AFB1) production, one of the most hazardous carcinogenic toxins for humans and animals. The current review presents the roles of these different genes and their possible impact on AFB1 production. We focus on the toxinogenic strains Aspergillus flavus and A. parasiticus, primary contaminants and major producers of AFB1 in crops. However, genetic reports on A. nidulans are also included because of the capacity of this fungus to produce sterigmatocystin, the penultimate stable metabolite during AFB1 production. The aim of this review is to provide a general overview of the AFB1 enzymatic biosynthesis pathway and its link with the genes belonging to the AFB1 cluster. It also aims to illustrate the role of global environmental factors on aflatoxin production and the recent data that demonstrate an interconnection between genes regulated by these environmental signals and aflatoxin biosynthetic pathway.

Canine oral mucosal melanomas (OMM) are the most common oral malignancy in dogs and few treatments are available. Thus, new treatment modalities are needed for this disease. Bacillus anthracis (anthrax) toxin has been reengineered to target tumor cells that express urokinase plasminogen activator (uPA) and metalloproteinases (MMP-2), and has shown antineoplastic effects both, in vitro and in vivo. This study aimed to evaluate the effects of a reengineered anthrax toxin on canine OMM. Five dogs bearing OMM without lung metastasis were included in the clinical study. Tumor tissue was analyzed by immunohistochemistry for expression of uPA, uPA receptor, MMP-2, MT1-MMP and TIMP-2. Animals received either three or six intratumoral injections of the reengineered anthrax toxin prior to surgical tumor excision. OMM samples from the five dogs were positive for all antibodies. After intratumoral treatment, all dogs showed stable disease according to the canine Response Evaluation Criteria in Solid Tumors (cRECIST), and tumors had decreased bleeding. Histopathology has shown necrosis of tumor cells and blood vessel walls after treatment. No significant systemic side effects were noted. In conclusion, the reengineered anthrax toxin exerted inhibitory effects when administered intratumorally, and systemic administration of this toxin is a promising therapy for canine OMM.
Potential for Managed Aquifer Recharge to Enhance Fish Habitat in a Regulated River

Published: March 2020

Managed aquifer recharge (MAR) is typically used to enhance the agricultural water supply but may also be promising to maintain summer streamflows and temperatures for cold-water fish. An existing aquifer model, water temperature data, and analysis of water administration were used to assess potential benefits of MAR to cold-water fisheries in Idaho’s Snake River. This highly-regulated river supports irrigated agriculture worth US $10 billion and recreational trout fisheries worth $100 million. The assessment focused on the Henry’s Fork Snake River, which receives groundwater from recharge incidental to irrigation and from MAR operations 8 km from the river, addressing (1) the quantity and timing of MAR-produced streamflow response, (2) the mechanism through which MAR increases streamflow, (3) whether groundwater inputs decrease the local stream temperature, and (4) the legal and administrative hurdles to using MAR for cold-water fisheries conservation in Idaho. The model estimated a long-term 4%–7% increase in summertime streamflow from annual MAR similar to that conducted in 2019. Water temperature observations confirmed that recharge increased streamflow via aquifer discharge rather than reduction in river losses to the aquifer. In addition, groundwater seeps created summer thermal refugia. Measured summer stream temperature at seeps was within the optimal temperature range for brown trout, averaging 14.4 °C, whereas ambient stream temperature exceeded 19 °C, the stress threshold for brown trout. Implementing MAR for fisheries conservation is challenged by administrative water rules and regulations. Well-developed and trusted water rights and water-transaction systems in Idaho and other western states enable MAR. However, in Idaho, conservation groups are unable to engage directly in water transactions, hampering MAR for fisheries protection.

É afirmado por parte da historiografia do tema que desde o início da década de 1920, o movimento anarquista teria começado sua decadência. De fato, concordamos que o anarquismo começa a perder sua base social de maneira irreversível nesse período, mas, neste artigo, afirmamos, concordando com outraspesquisas e também olhando para além do eixo Rio-São Paulo, que o anarquismo e suas estratégias ainda representavam uma opção de luta de boa parte da classe trabalhadora. A circulação de ideias através de seus grupos móveis e suas ligações em entidades sindicais translocais, a partir da Confederação Operária Brasileira (COB) fizeram o anarquismo, que estava sendo atacado em seus núcleos mais usuais, conserva-se, além de se legitimar em lugares diferentes e longínquos entre si, fato muito importante para a não extinção total do anarquismo, e para a conservação do sindicalismo revolucionário, estratégia não só de anarquistas, mas de muitos trabalhadores.

Authors: Klyuchnikova N. , Piskareva A. , Urvanov K. , Gordeev S. , Genov I.
Published: March 2020

Polymers are increasingly replacing conventional materials such as wood, metals, natural fibers. This is due to a number of advantages of polymer materials over classic ones: increased chemical resistance to aggressive environments, high strength indicators and durability in the operation of products. In addition, polymeric materials are actively used in the food industry.

The use of polymer packaging is reaching global proportions. Improving production technologies and formulations allows to create new polymer composites with improved properties, which gives the rapid growth of the polymer industry.

In order to impart the necessary properties, fillers are introduced into the polymeric material. By introducing such additives into the polymer, it is possible to control the properties of the material obtained, for example, viscosity, density, transparency, bactericidal and other important properties.

The article considers the influence of shungite on the operational properties of the finished composite based on low-pressure polyethylene.

The research results showed that the composite obtained provides the highest characteristics with respect to light reflection and absorption for all wavelength regions that are important during operation, has bactericidal properties, and it has been proved that in the shungite-filled polymer, a shift in the temperature of the onset of thermal degradation towards higher temperatures is observed. The composite acquires higher operational and physico-mechanical properties.

Under-nutrition is still a major contributor to disease and poor growth in vulnerable populations. Prolonged undernutrition affects physical health, mental and social development of children and exacts a heavy cost to their families and society at large. Insufficient food availability is an important cause of undernutrition, the ability or willingness to consume available foods is another major factor. Picky eating is one of the behaviors that children with difficulty or not to accept foods. Picky eating is relatively common among infants and children, often causing anxiety for parents and caregivers. Picking eating is often linked to nutritional problems, and is also the cause that parents take their child to doctor for examination and consultation. Objectives: To describe prevalence of picky eaters and nutritional status of children aged 1 to 5 and to find out the relationship between picky eating and nutritional status of children. Methods: This was a cross-sectional study. A sample size of 1100 children aged 1 to 5 had been selected and studied by using questionnaire for interviewing parents or caregivers to estimate prevalence of picky eaters; measuring weight, length/height to access nutritional status of children. Results: Prevalence of picky eaters based on parents or caregivers’ opinion and according to researchers were 43.3% and 22.2%, respectively. The most common signs of picky eating reported by parents or caregivers were eat slowly, mealtime lasted for over 30 minutes (39.7%), eat less (31.7%), keep food in mouth (23.5%). 35.9% of picky eaters had signs at the period of complementary feeding. Prevalence of underweight, overweight and stunting were 7.5%, 3.6% and 10.9%, respectively. There was no relationship between picky eating and stunting (p>0.05) but strong relationship between picky eating and underweight (p<0.001), wasting (p<0.001). Picky eaters were 4.02 times at risk of underweight compared to non-picky eaters (95% CI: 2.54-6.36). Conclusions: Picky eating is common and a risk factor of underweight, wasting. It should be a big concern to public health workers. Key words: Picky eating, nutritional status, children aged 1 to 5, Vietnam
Cuerpo y bolero. La Lupe: una aproximación en clave de artefacto cultural
Authors: Ascanio Barrios Celiner de Jesús , Chasi Escobar Christian Paul
Published: March 2020

El cuerpo es el lugar en donde se inscribe la subjetividad. No existe subjetividad sin cuerpo. Más allá de las teorías políticas, los estudios sobre esta categoría se abren también a perspectivas que lo conectan con la vida y el deseo. El cuerpo erótico constituye así una deriva que dialoga con las Políticas del Afecto y los Estudios Culturales. Nuestro trabajo parte de un fenómeno, pensado como “artefacto cultural”, que se origina en la música y estalla hacia otros campos generando una productividad. El objetivo del presente artículo es analizar categorías como cuerpo y erotismo y su relación con el bolero, a partir de una figura que constituye una “personalidad de excepción” en quien vida y obra se mezclan para dar lugar a un artefacto cultural: La Lupe. Nuestro corpus está conformado por formatos que permitirán leer esta productividad que representa La Lupe en Latinoamérica durante el siglo XX. Partiremos de las propuestas teóricas de Roger Dadoun sobre erotismo, cuerpo y deseo, y de las discusiones sobre “originalidad” de Gilles Deleuze, en diálogo con diferentes lecturas sobre el bolero que permitirán comprender las categorías anteriores, tomando en cuenta la especificidad que tienen dentro del imaginario latinoamericano.

PHYSICAL ACTIVITY AND EXERCISE AS A KEY FACTOR IN SUCCESSFUL AGING
Authors: Passaro Angelina , Capatti Eleonora , Dalla Nora Edoardo
Published: March 2020

Aging is associated with several changes in body composition and metabolism, including sarcopenia, sarcopenic obesity and decrease in bone mass; aerobic capacity, muscle mass and strength tend to decline progressively. These changes have considerable impact on the ability to perform daily activities, especially when associated with chronic diseases, such as type 2 diabetes, cardio-vascular disease and dyslipidemia, as well as geriatric syndromes, like mobility impairment, falls and frailty. Scientific research has shown that physical activity and exercise can slow the physiological aging clock. Particularly, active elderly people seem to age “successfully” compared to sedentary ones. The aim of our work is to review evidence-based recommendations for physical activity, exercise and diet that would help to preserve muscle mass and strength, and to reduce the gain of fat mass in older adults. Increasing levels of physical activity, in particular resistance training mixed with aerobic exercise, and adequate protein nutrition intake should be an integral component in the prevention and treatment of sarcopenia, sarcopenic obesity and metabolic syndrome in elderly subjects.
Intelligence, Artificial and Otherwise
Authors: Dumouchel Paul
Published: March 2020

The idea of artificial intelligence implies the existence of a form of intelligence that is “natural,” or at least not artificial. The problem is that intelligence, whether “natural” or “artificial,” is not well defined: it is hard to say what, exactly, is or constitutes intelligence. This difficulty makes it impossible to measure human intelligence against artificial intelligence on a unique scale. It does not, however, prevent us from comparing them; rather, it changes the sense and meaning of such comparisons. Comparing artificial intelligence with human intelligence could allow us to understand both forms better. This paper thus aims to compare and distinguish these two forms of intelligence, focusing on three issues: forms of embodiment, autonomy and judgment. Doing so, I argue, should enable us to have a better view of the promises and limitations of present-day artificial intelligence, along with its benefits and dangers and the place we should make for it in our culture and society.

Authors: Grinchel’ B. M. , Nazarova E. A.
Published: March 2020

The presented study examines methods for analyzing and managing sustainable economic development of Russian regions and possible criteria for assessing and improving sustainability.

Aim. The study aims to provide a theoretical and empirical justification for the use of regional competitive attractiveness assessment to manage economic development and improve its sustainability.

Tasks. Based on the measurement and analysis of economic competitive attractiveness indicators and their mathematical treatment, the authors assess the sustainability of development of Russian regions in 2013–2017 and the causes of deviations from progressive growth.

Methods. This study proposes a mathematical tool for measuring the sustainability of Russian regions by assessing their competitive attractiveness and develops a typology of sustainability in the mathematical space of two variables.

Results. Methods for analyzing and managing the sustainability of economic development of Russian regions under the influence of political and economic challenges and risks are proposed. The level and dynamics of regional competitive attractiveness are taken as a criterion of sustainability of economic development. The authors provide methods and indicators for assessing economic competitive attractiveness and criteria for measuring the sustainability of development, which allow them to draw conclusions about the reaction of different regions to the challenges and risks of development in 2013–2017. The study proposes a management scheme for sustainable regional development with a focus on the comprehensive improvement of regional economic competitive attractiveness and potential ways to improve it, including training of municipal and regional managers in crisis management associated with economic and political challenges and risks.

Conclusions. Based on the proposed criterion of economic development sustainability and assessment of the competitive attractiveness of regions and their rankings, it is shown that in 2013–2017 45 out of 83 regions were developing sustainably; by 2017, 19 regions out of the 32 that suffered losses in the competitive attractiveness level and rankings in 2015–2016 have managed to restore the sustainability of economic development and their rankings. This study proves that regions with a high level of economic competitive attractiveness show increased sustainability of development.

Tyrimo tikslas – ištirti dozuoto fizinio krūvio poveikį paauglių skeleto raumenų sistemai.
Tyrimas buvo vykdomas 2018 m. kovo – 2019 m. sausio mėnesiais Vilniaus Senvagės gimnazijoje ir Vaikų ligoninėje, viešosios įstaigos Vilniaus universiteto ligoninės Santaros klinikų filiale. Tyrime dalyvavo 14–17 metų paaugliai, kurie savanoriškai sutiko dalyvauti tyrime. Tiriamųjų imtį sudarė 46 mokiniai, iš kurių – 27 merginos ir 19 vaikinų. Mokinių kojų raumenų jėgos bei dinaminės ištvermės vertinimui naudotas izokinetinis dinamometras „Biodex multi-joint system 4-pro“, o ūgiui ir bendrajai kūno masei nustatyti – medicininės svarstyklės. Dozuoto fizinio krūvio intervencijos poveikiui tirti naudotas veloergometras. Statistinei duomenų analizei atlikti buvo naudojamos MS Excel 2016 ir SPSS Windows 17.0 programos.
Rezultatai. Dviejų mėnesių trukmės dozuoto fizinio krūvio taikymas padidino maksimalią jėgą, jėgos ir kūno masės santykį bei nuveiktą darbą (p≤0,05). Praėjus dviejų mėnesių trukmės intervencijos taikymui, papildomai du mėnesius laikantis fizinio aktyvumo rekomendacijų, pasiekti skeleto raumenų jėgos ir dinaminės ištvermės rezultatai neregresavo (p≤0,05). Atitinkamai, keturis mėnesius taikant vienodą dozuotą fizinį krūvį, taip pat padidėjo skeleto raumenų jėga ir dinaminė ištvermė (p≤0,05), tačiau nuo antro intervencijos mėnesio raumenų jėgos ir dinaminės ištvermės didėjimo tendencija nebuvo statistiškai reikšminga (p>0,05). Taikant dviejų ir keturių mėnesių trukmės intervenciją, agonistų ir antagonistų santykis tyrimo eigoje nepakito (p>0,05). Lyginant fizinio krūvio poveikį abiem tiriamųjų grupėms, pastebėta, kad po dviejų mėnesių intervencijos, jėgos ir kūno masės santykis buvo didesnis, nei tos grupės, kuriai buvo taikyta keturių mėnesių trukmės intervencija (p≤0,05). Tiriamųjų grupei, kuriai buvo taikyta keturių mėnesių trukmės intervencija, agonistų ir antagonistų santykis pirmojo ir antrojo tyrimo metu buvo didesnis, nei tos grupės, kuriai buvo taikyta dviejų mėnesių trukmės intervencija (p≤0,05), tačiau skirtumų tarp kitų jėgos ir dinaminės ištvermės rodiklių nenustatyta (p>0,05).
Išvados. Dviejų mėnesių trukmės dozuoto fizinio krūvio taikymas vienodai padidino skeleto raumenų jėgą ir dinaminę ištvermę agonistams ir antagonistams. Du mėnesius namuose laikantis fizinio aktyvumo rekomendacijų, skeleto raumenų jėgos ir dinaminės ištvermės rezultatai neregresavo. Keturių mėnesių trukmės dozuoto fizinio krūvio taikymas vienodai padidino skeleto raumenų jėgą ir dinaminę ištvermę agonistams ir antagonistams, tačiau nuo antro intervencijos mėnesio raumenų jėgos ir dinaminės ištvermės didėjimo tendencija nebuvo statistiškai reikšminga. Ir keturių mėnesių trukmės dozuoto fizinio krūvio taikymas, ir dviejų mėnesių intervencija, po kurios du mėnesius namuose laikytasi fizinio aktyvumo rekomendacijų, vienodai padidino raumenų jėgos ir dinaminės ištvermės rodiklius.

Darbo tikslas – nustatyti 1995-2016 metų laikotarpio naujagimių, kurių motinos nėštumo metu vartojo narkotikus, skaičių; ištirti moterų sociodemografinius, akušerinės anamnezės ir sveikatos būklės rodiklius; naujagimių fizinės ir sveikatos būklės ypatumus.
Darbo metodika. Tyrimo duomenys rinkti naudojantis Higienos instituto sveikatos informacijos centro gimimų medicininių duomenų informacine sistema. Atrinkti naujagimiai, kurių motinos nuo 1997 metų nėštumo metu vartojo narkotikus ir (ar) kuriems buvo diagnozuota patologija dėl motinos narkomanijos. Nagrinėti motinų sociodemografiniai rodikliai (amžius, tautybė, išsilavinimas, šeiminė padėtis), buvę nėštumai ir gimdymai, ligos nėštumo metu, naujagimių fizinės (ūgis, svoris, galvos apimtis) ir sveikatos būklės rodikliai (baigtis, diagnozės dėl narkotikų poveikio ir kitos ligos). Duomenys analizuoti naudojant MS office Excel 2016 ir SPSS statistics 25 programas.
Rezultatai. Iš viso atrinkti 414 (0,06 proc. nuo visų gyvų gimusių) naujagimių, kurių motinos nėštumo metu vartojo narkotikus. Nagrinėjamuoju laikotarpiu bendrasis tokių naujagimių skaičius didėjo (1995 m. – 0,02 proc., 2016 – 0,1 proc.). Ketvirtadalis (24 proc.) gimė neišnešioti (reikšmingai daugiau, palyginus su neišnešiotų naujagimių dalimi tarp visų gyvų gimusių p<0,001). Vidutiniai naujagimių fizinės būklės rodikliai buvo: svoris 2796,7 (±596,7) g, ūgis 48,9 (±3,5) cm, galvos apimtis 33,2 (±2,4) centimetrai. Vidutinis motinų amžius – 26,9 metai. Palyginus su bendrosios populiacijos tautine sudėtimi, patikimai didesnę dalį sudarė rusės (19,3 proc.), lenkės (9,7 proc.) ir kitų tautybių (6,5 proc.) moterys. Daugiau kaip pusė moterų (65,0 proc.) gyveno vienos; beveik pusė (44,2 proc.) – neturinčios vidurinio išsilavinimo. Didelė dalis naujagimių (56,3 proc.) gimė turėdami naujagimių abstinencijos sindromą, tačiau ne visos (tik 47,3 proc.) tokių naujagimių motinos pripažino nėštumo metu vartojusios narkotikus. Daugiau nei pusė naujagimių (60,0 proc.) buvo perkelti tolesniam gydymui, dažniausiai dėl naujagimių abstinencijos sindromo (39,1 proc.), ar įgimtos infekcijos (20,3 proc.).
Išvados. Tyrimo laikotarpiu naujagimių, kurių motinos nėštumo metu vartojo narkotikus, skaičius padidėjo nuo 0,02 proc. (1995 m.) iki 0,1 proc. (2016 m.). Narkotikus nėštumo metu reikšmingai dažniau vartojo žemo išsilavinimo, vienos gyvenančios moterys. Naujagimių vidutiniai fizinės būklės rodikliai buvo statistiškai reikšmingai mažesni, negu bendrosios populiacijos; naujagimiai 4 kartus dažniau buvo neišnešioti. Daugiau nei pusei naujagimių reikėjo tolesnio gydymo, dažniausiai dėl naujagimių abstinencijos sindromo ir (ar) įgimtos infekcijos.

Senyvo amžiaus žmonių griuvimas yra susilpnėjusios fizinės funkcijos pasekmė. Šio tyrimo tikslas – pa­lyginti skirtingų pratimų programų poveikį senyvo amžiaus asmenų fizinei funkcijai ir griuvimo rizikai.
Tyrimo metodai. Tyrimas vyko 2018-2019 metais­viešosios įstaigos Karoliniškių poliklinikos ambu­latorinės reabilitacijos skyriuje. Įtraukiamų į tyrimą asmenų kognityvinė funkcija įvertinta naudojant Monrealio kognityvinį testą, fizinis aktyvumas – fi­zinio aktyvumo skalę senyvo amžiaus asmenims. Dviem asmenų per 65 m. amžiaus grupėms 8 savaites buvo taikytos skirtingos fizinių pratimų programos. Otago pratimų programa palyginta su liemens stabi­lizavimo, galūnių raumenų stiprinimo bei dinaminės pusiausvyros lavinimo pratimų programa. Fizinių funkcijų, griuvimo rizikos ir baimės tyrimas atliktas du kartus – prieš vykdant pratimų programą ir bai­gus ją. Fizinės funkcijos vertintos naudojant hidrau­linį rankos dinamometrą, trumpąjį fizinės funkcijos testų rinkinį ir Bergo pusiausvyros skalę; griuvimo rizika – „Atsistoti ir eiti“ trukmės testą; griuvimo ir judėjimo baimė – tarptautinę griuvimų efektyvumo skalę ir klausimyną apie judėjimo baimę.
Rezultatai. Tyrime dalyvavo 50 asmenų (41 moteris ir 9 vyrai), kurių vidutinis amžius – 70,1±3,6 m. Vi­dutinis visų tiriamųjų fizinio aktyvumo lygis buvo 188,8±77,2 balų pagal PASE klausimyną. Per pasta­ruosius 12 mėnesių bent vieną kartą pargriuvę buvo 70 proc., griuvimo baimę jautė 68 proc. tiriamųjų. Po 8 savaičių, ir pritaikius Otago pratimų programą, ir liemens stabilizavimo programą, statistiškai reikš­mingai padidėjo tiriamųjų fizinis pajėgumas, apatinių galūnių raumenų jėga, moterų plaštakos raumenų jėga, ėjimo greitis ir pagerėjo pusiausvyra. Lyginant šiuos rodiklius tarp grupių, reikšmingų skirtumų ne­nustatyta. Vidutinė „Atsistoti ir eiti“ testo atlikimo trukmė neviršijo 14 sek., ji sumažėjo abiejose tiria­mųjų grupėse, tačiau tarp grupių skirtumų nebuvo. Tyrimo pradžioje griuvimo baimė įvertinta kaip vi­dutinė (21,9±5,2 balo pagal FES-I), o po 8 savaičių abiejose grupėse ji sumažėjo ir buvo įvertinta kaip nedidelė (atitinkamai 18,9±2,5 ir17,9±2,5 balų); tarp grupių reikšmingų skirtumų nenustatyta.
Išvada. Ir pritaikius Otago pratimų programą, ir lie­mens stabilizavimo programą senyvo amžiaus as­menims, po aštuonių savaičių padidėjo jų apatinių galūnių raumenų jėga, moterų plaštakos raumenų jėga, ėjimo greitis ir pagerėjo pusiausvyra, sumažėjo griuvimo baimė ir rizika, tačiau skirtumų tarp šių programų poveikio nenustatyta.
