Authors: Sun Shilong , Huang Haodong , Ding Jian , Lu Wenjie , Wang Dong
Published: December 2024

In this paper, we address the challenge of predicting the remaining useful life (RUL) of aero-engines, which are critical components of aircraft that operate under increasingly extreme conditions as engine performance enhances. Ensuring the safety and reliability of these engines is
paramount. To this end, we introduce a novel RUL prediction methodology that leverages grey similarity multiscale matching. This approach employs the robust capabilities of Long Short-Term Memory (LSTM) networks for processing time-series data. Specifically, an LSTM Stacked AutoEncoder (L-SAE)
is designed to extract pivotal operational features of the engine, thereby delineating its degradation trajectory. Furthermore, the grey correlation analysis is utilized to assess the similarity between these degradation trajectories, which is complemented by a multi-time scale sliding window
technique for enhanced similarity matching. Subsequently, kernel density estimation is applied to gauge the uncertainty associated with the prediction outcomes. The efficacy and superiority of our proposed method are demonstrated through the validation of the experiment study. Comparative
analysis reveals that our method outperforms existing techniques in key evaluation metrics, underscoring its potential applicability to large-scale datasets. This validation not only confirms the method's effectiveness but also its advantage in predicting the RUL of aero-engines with greater
accuracy and reliability.
Monitoring Mooring Lines of Floating Offshore Wind Turbines: Autoregressive Coefficients and Stacked Auto-Associative-Deep Neural Networks
Authors: Sharma Smriti , Nava Vincenzo
Published: December 2024

This study introduces a pioneering monitoring system designed to mitigate operational costs and enhance the sustainability of Floating Offshore Wind Turbines (FOWT). The proposed framework combines Autoregressive models with a Stacked Auto-Associativebased Deep Neural Network (AANN-DNN)
to detect and classify damages in mooring systems of FOWTs. By extracting damage-sensitive features (DSFs) using the AR models from time-series data and employing unsupervised learning in the auto-associative neural network, followed by supervised training with DNN, the approach demonstrates
exceptional accuracy in damage identification and classification. Numerical simulations conducted using NREL's OpenFAST software under diverse metocean conditions validate the method's efficacy, offering a promising solution for efficient FOWT mooring line monitoring.
A concise review of transfer learning and generative learning for autonomous and robotic systems fault detection and diagnosis
Authors: Li Chenyi , Zhang Long
Published: December 2024

In autonomous and robotic systems, the importance of Fault Detection and Diagnosis (FDD) technologies has increasingly grown as these systems find widespread application across various sectors. There are a wide range of data-driven machine-learning approaches for FDD. These methods
often require large amounts of normal and fault data for model training. In scenarios with limited data availability, transfer learning boosts learning efficiency by transferring prior knowledge. In contrast, generative learning, such as Generative Adversarial Networks (GANs), enhances the
accuracy and generalization capabilities of fault diagnosis models by generating simulated fault data. While several reviews focus on component-specific fault analysis via transfer learning and generative learning, such as bearings and gearboxes, research on system-level fault diagnosis is
comparatively scarce. In this context, the aim of this paper is to review the application of transfer learning and generative learning in FDD technologies for autonomous and robotic systems. The article expands the research scope of FDD from individual components to entire systems. It explores
the potential value and challenges of two learning strategies in advancing FDD technology. Finally, it presents new perspectives and directions for future research in this field.
Condition monitoring and failure analysis of a liquefied natural gas plant cryogenic heavies removal column reflux pump
Authors: Pereira Eloi S
Published: December 2024

Critical rotating equipment machines like pumps, gas compressors, heavy duty gas turbine and diesel engines are subject to wear and aging. The materials and components they are made from degrade over time, and if no action is taken they will eventually fail. Fortunately most types of
failure can be prevented by maintenance. To plan maintenance effectively, the plant operator must have accurate information, which components need repairing or replacing, and when. Maintenance planning management plays a big role in preserving equipment reliability and availability of a liquefied
natural gas (LNG) plant. This paper investigates failures on cryogenic heavies removal column reflux pump on LNG plant. Root cause analysis (RCA), was conducted to determine, the pump failure pattern. Failure of the thrust equalizing mechanism (TEM) caused excessive downward thrust in the
rotor, as demonstrated by the gap seen between the alignment of the wear ring and casing on the seized impeller. Debris (aluminium, stainless steel, and iron) from the pump, obstructed the flow to the ball bearing and caused lack of lubrication and cooling for the bearing which consequently
increased the bearing temperature, created localized heat vaporization and the bearings catastrophically failed. The pump casing was found with damage from the impeller thrusting against it during its failure with deposits from the wear ring embedded in the contacted area. This placed the
bearing into axial strain and caused the failure. Condition monitoring graphs of the pump performance prior to failure were critically analysed and presented in this paper.
Instrumentation condition monitoring vibration and failure analysis of screw air compressor package in liquefied natural gas plant
Authors: Pereira Eloi S
Published: December 2024

Instrumentation, for conditioning monitoring on rotating equipment is vital for determining whether the equipment is running correctly or not. Measuring the bearing temperature or shaft vibration can identify any potential problems when running the equipment. Identification of a potential
problem before it arises allows operating engineers to shut down the machine or make appropriate changes to the machine operation before the problem occurs. This is more economical as shutting down a machine and making the relevant alterations is cheaper than allowing it to fail and performing
the repairs. This paper investigates several sources of vibration on a screw air compressor package in a liquefied natural gas (LNG) plant. Root cause failure analysis (RCFA) approach is used to analyse historical failure and vibration analysis data. The main vibration causes and consequent
failures on compressor are: resonance of the interstage condensate separator, important levels of dynamic pressure and vibration at low pressure (LP) and high pressure (HP) compression stage frequencies and harmonics, excessive axial force exerted on the main rotor shaft causing the bearing
to run on the back edge and subsequently failing due to the excessive axial forces, inferior axial bearings, failing due to poor design or inferior material composition. In order to avoid other failures, the interstage condensate separator was redesigned to shift its natural frequency and
cancel the resonance, two broadband mufflers were designed, one muffler for each stage, centred on 1244 Hz for the LP muffler (3 times LP stage compression fundamental), and on 1816 Hz for the HP muffler (2 times HP stage compression, harmonic 2). Condition monitoring graphs, of vibrations,
and excitation sources are presented to give an overview of the acceleration, pressure and velocity RMS (mm/s), spectrums on the compressor before and after the installation of the mufflers.
Impulsive Mode Decomposition and its Four Application Cases to Impulsive Signal Extraction
Authors: Hou Bingchang , Wang Dong
Published: December 2024

Impulsive signal components widely exist in nature, and the extraction of impulsive signal components has attracted great attention from various fields such as machine fault diagnosis, non-destructive testing, ECG denoising, etc. Although signal decomposition methods, including empirical
mode decomposition, variational mode decomposition, wavelet packet transform, and singular value decomposition, have been applied to extract impulsive signal components, they still suffer from problems such as failure extraction of weak impulsive signal components and mode mixing, and they
are also hard to adaptively determine the number of impulsive signal components. The authors recently proposed an impulsive mode decomposition (IMD), which is a new and promising method tailored for impulsive signal analysis. Therefore, this work reported four application cases of the IMD,
including gearbox fault diagnosis, bearing fault diagnosis, nondestructive signal denoising, and ECG signal denoising. These cases show the wide application perspective of the IMD.
Natural Language based Information in Intelligent Condition Monitoring and Control
Authors: Juuso Esko K.
Published: December 2024

Materials in natural language can provide useful information about variable interactions. Generative AI tools are introduced for finding connections within this material. However, everything remains in natural language. A consistent representation is needed to use them with data based
on measurements in quantitative analysis. Generalised norms provide informative features from measurements and signals. Intelligent indicators in the range [-2, 2], are obtained by using generalised norms in the nonlinear scaling. These indicators are also suitable for the temporal analysis.
Information which does not contain numerical values, the corresponding scaled values can be obtained by using interactions with labels like {very low, low, normal, high, very high} or {fast decrease, decrease, constant, increase, fast increase}. The linguistic terms can be interpreted as fuzzy
numbers, which can be made sharper or wider with powering modifiers 'extremely', 'very', 'more or less' and 'roughly', and then processed with the conjunction, disjunction and negation. All these can be represented with mathematical expressions within the range [-2, 2]. The methodology is
used in the analysis of the event data: the information represented with these numbers produces a real-valued relation base to be used to analyse interactions. Known relationships can also be handled with the fuzzy calculus and the extension principle to keep the uncertainty in the calculation.
Hybrid models can utilize both crisp and uncertain information in condition monitoring and control.
Estimation of Remaining Useful Life (RUL) of rolling element bearings based on the Adaptive Kernel Kalman Filter
Authors: Li Zhen , Zhu Rui , Verwimp Toby , Wen Hao , Gryllias Konstantinos
Published: December 2024

Estimation of Remaining Useful Life (RUL) of rolling element bearings is challenging, making optimal scheduling of shutdowns and maintenance tasks difficult. The last years, a number of prognostic methodologies have been proposed and they could mainly be categorized into AI based and
statistical based. AI-based approaches need a large volume of data and more specifically labelled RUL data to train the model, setting hard obstacles in the implementation in industry. The statistical based ones, which include Kalman filter and its family members, often present accuracy problems
due to the nonlinearity of bearings' degradation trends. In this paper, targeting to RUL prediction of rotating machinery, a Health Indicator (HI) is first extracted based on signal processing applied on time, frequency and/or time-frequency domains. Then anomaly thresholds and stop criteria
are set in the prediction process. Finally, a methodology based on the recently proposed Adaptive Kernel Kalman Filter (AKKF) is introduced for the estimation of the RUL. The proposed methodology is applied on the publicly available XJTU Dataset and on a dataset captured on the KU Leuven Gearbox
Prognostics Test Rig. The performance of the methodology is evaluated using different models and compared against state of the art methods, such as the Extended Kalman Filter (EKF).
Exploring the Gravitational Impact of Spring Tides on Earthquake Occurrence in Central Asia
Authors: Nekrasova Anastasia , Danabayeva Aigul , Katubayeva Assel
Published: December 2024

In this study, we analyzed variations in seismic activity in relation to the syzygy of the Sun, Moon, and Earth, corresponding to the semilunar or spring tide (ST) cycle. We focused on two regions within the Central Asian Orogenic Belt: the North Tien Shan region (NTSR) and the Xinjiang Uygur tectonic province (XUTP), using data from two regional earthquake catalogs. For the NTSR, we used data from the Seismological Experimental and Methodical Expedition in Almaty, Kazakhstan, covering 1 January 1970 to 31 July 2022. For the XUTP, we utilized data from the Data Management Centre of China National Seismic Network at the Institute of Geophysics China Earthquake Administration, spanning 1 January 1987 to 30 June 2019. We applied the nonparametric Kuiper’s test to evaluate cyclic variations in seismic activity, focusing on different magnitude thresholds in the regional catalog. For both regions, the original catalog as well as the catalogs of mainshocks and aftershocks were analyzed. The nearest-neighbor declustering method was employed to decompose the seismic catalogs. Kuiper’s test statistics revealed varying trends in the occurrence times for mainshocks and aftershocks during ST cycles. The test showed “the good-to-fit” to a uniform distribution for the timing of mainshocks within the ST cycle. Kuiper’s test revealed notably consistent trends in aftershock occurrence times during ST cycles with a significance level α of 0.001 or less in both regions analyzed. These results suggest a potential correlation between aftershock activity and the gravitational effects of the ST cycle. The most substantial decrease in aftershocks occurs during the micromoon ST cycle, when the distance between the Moon and the Earth exceeds 400,000 km.
Direct Waveform Inversion for Irregularly Layered Media
Authors: Liu Zhonghan , Zheng Yingcai , Zhou Hua-Wei , Hu Hao
Published: December 2024

Full waveform inversion is based on iterative perturbation approaches and often encounters convergence problems when the global initial model is far from the true model. As an alternative solution, our direct waveform inversion (DWI) can accurately invert for the acoustic properties of layered media without requiring a global initial model and furthermore DWI convergence is unconditional. However, previous studies of DWI focused only on inverting 1D horizontally layered media using incident plane waves. Its performance in higher dimensions is yet to be evaluated. Now, we have developed a new DWI scheme designed to invert for 2D irregularly multilayered acoustic media using point-source data. Leveraging the advantages of boundary integral equations in handling irregular layer boundaries, we derived a new wavefield representation and implemented it in our 2D DWI. We incorporated a localized imaging and inversion process for determining the geometries of the irregular interfaces. Similar to our previous 1D DWI, our new 2D DWI explicitly enforces the time–space causality property of the wavefields, retaining the key advantage of not requiring a global initial model and avoiding local minimum and cycle-skipping pitfalls. We tested our 2D DWI on two irregular layered models using explosive point sources. The results confirm that our 2D DWI can effectively and accurately invert for P-wave velocities as well as irregular subsurface geometries.

Published: December 2024

Coronary Heart Disease is one of the leading causes of death worldwide. The morbidity, mortality, and costs involved with CHD are a significant burden on healthcare systems. The complexity of the disease necessitates a multi-faceted approach to treating those suffering from it. As an emerging healthcare field, personalized health coaching is poised to be a highly effective care method for those suffering from the disease. In this thesis, a review of the literature is conducted, covering three meta-analyses that aim to answer the question of whether health coaching is an effective method of managing CHD. Each article in the review focuses on a different aspect of health coaching and its effectiveness in treating coronary heart disease and its parent, cardiovascular disease. A comprehensive review of these meta-analyses determined that personalized health coaching is an effective method for treating coronary heart disease. However, there are certain various directions that should be explored in future research.

Published: December 2024

Nanoparticle applications have been studied in many fields in recent years. Among these studies, the synthesis of nature-friendly and health-friendly nanoparticles through green synthesis attracts much attention. These investigations also highlight the significance of several plant species, many of whose worth and traits remain unknown. The goal of this work is to create zinc oxide and selenium nanoparticles from Verbascum kotschyi Boiss. & Hohen., a plant species that hasn't received much attention, and to ascertain the antioxidant and antibacterial qualities of these nanoparticles. To accomplish this, three distinct techniques (DPPH, CUPRAC, and FRAP) were used to assess the produced nanoparticles' in vitro antioxidant capabilities after SEM, EDX, and FTIR analyses. Furthermore, the disk diffusion technique was utilized to ascertain the antibacterial efficacy of these nanoparticles against both gram-positive and gram-negative bacteria and fungus In conclusion, V. kotschyi-derived zinc oxide nanoparticles outperformed selenium nanoparticles in terms of antibacterial activity. But when it came to antioxidant activity, selenium nanoparticles outperformed zinc oxide nanoparticles. Thus, it was determined that the products created by nanoparticle synthesis from Verbascum kotschyi have properties that can be used in different fields.
Analysis of the Variations Within Quercus ilex L. and the Evaluation of Morphological Types Based on Chloroplast and Nuclear DNA Sequences
Authors: Yılmaz Aykut
Published: December 2024

Quercus ilex, evaluated within evergreen oaks, has a wide geographic distribution in the Mediterranean basin. Hybridization and gene flow are effective and frequently observed mechanisms in Q. ilex. Additionally, weak reproductive barriers between closely related taxa in zones of geographical contact further increase genetic diversity and subsequent taxonomic problems. Two morphological types, known as rotundifolia and ilex, are defined based on the variations between Q. ilex populations appearing as a result of all these factors. However, it is still controversial whether morphological types: ilex and rotundifolia are subspecies of Q. ilex or two separate species. In this study, short DNA sequences that consist of matK gene-partial trnK gene intron of chloroplast DNA and ITS1-5.8S rRNA gene-ITS2 of nuclear DNA were used to overcome such difficulties and to reveal the variations between Q. ilex populations. All Q. ilex populations based on both barcoding regions were determined and examined using the Molecular Evolutionary Genetics Analysis (MEGA 11). The analysis such as base substitutions, variable and parsim-info sites, transitional and transversional base substitution ranges (%), and nucleotide frequencies (%) was performed and transitional substitutions according to the transversional substitutions for both barcoding regions were observed in the high-value. Furthermore, the sequences belonging to nuclear DNA in comparison to other barcoding regions exhibited higher variable and parsim-info sites. Finally, Maximum Parsimony (MP) dendrograms for both barcoding regions were drawn to evaluate the populations belonging to Q. ilex in terms of their variations, phylogenetic-evolutionary relationships, and taxonomic status. Although both barcoding regions support the separation of Q. ilex populations based on different morphological types, matK gene-partial trnK gene intron sequences exhibited clearer and more informative results than ITS1-5.8S rRNA gene-ITS2 sequences.
Confirmation of the Natural Distribution of Euphorbia condylocarpa M.Bieb. (Euphorbiaceae: Sect. Helioscopia, Subsect.Galarhoei ) in Türkiye
Authors: Behçet Lütfi
Published: December 2024

This study; it is about the verification of the distribution of Euphorbia condylocarpa Boiss. & Heldr. (Euphorbiaceae), for which there is no reliable information about its existence in Türkiye. Because, the most important website regarding the distribution of plants distributed in Türkiye(Bizimbitkiler website) and the most up-to-date and comprehensive study called "Bizim Bitkiler Listesi (Damarlı Bitkiler)” do not accept the existence of this species in Türkiye. It is stated that the existence of this species in Türkiye needs to be confirmed. The closest species to the E. condylocarpa, which we focused on in order to eliminate doubts about its distribution in Turkey, is in tuberous form Euphorbia apios L.. It is distinguished from E. apios by the fact that the cauline leaves of E. condylocarpa are cordate–auriculate at the base and the number of axillary rays is more than 6 (to 30). In addition, the description of E. condylocarpa, the ecological information in the area where it develops, and some features of the species that differ from the known description are also emphasized.

Authors: Vieira Edson Trajano , Silva Ernesto Donizetti Aparecido da
Published: December 2024

Após a Constituição de 1988, o Brasil experimentou mudanças no federalismo fiscal, descentralizando receitas para estados e municípios. Apesar da expectativa de descentralização de responsabilidades municipais, o cenário fiscal federal restritivo limitou isso. A Lei 9.478/97 aumentou as receitas de royalties para municípios costeiros de São Paulo, impulsionando investimentos em infraestrutura e serviços públicos. No entanto, falta um plano de sustentabilidade e diversificação econômica local para enfrentar o esgotamento dos recursos petrolíferos que deveriam ser direcionados para investimentos que considerem as potencialidades de cada município. Para conduzir este estudo, empregamos uma pesquisa exploratória de natureza qualitativa, com um delineamento bibliográfico e documental. Este estudo investiga o impacto desses recursos nas receitas tributárias e no desenvolvimento econômico dos municípios de São Sebastião e Ilhabela, concluindo que, embora tenham impulsionado investimentos e serviços públicos, a falta de direcionamento estratégico pode comprometer o futuro econômico dessas regiões.

Myotonia may be a sign that prompts genetic testing for myotonic dystrophy type 1
Authors: Eser Metin , Hekimoğlu Gulam , Kutlubay Büşra
Published: December 2024

Objectives: Myotonic dystrophy type 1 (DM1) is an autosomal dominant disorder characterized by myotonia, atrophy, and muscle weakness. Even though myotonic discharges can be shown on electromyography in DM1 instances, it is still difficult to distinguish DM1 clinically from other myotonic disorders. We aimed to examine the relationship between DM1 and myotonia.
Methods: Data from 22 patients who had myotonia were analyzed retrospectively. Patients with DM1 (n=9) and non-DM1 myotonia (n=13) were categorized by genetic testing.
Results: There was a significant difference in the incidence rates of myotonia (P=0.0001) between 8 out of 9 DM1 patients (89%) and 1 out of 13 non-DM1 (8%). Myotonic discharges were seen in 7 of the 9 DM1 (78%) patients. On the other hand, only 2 out of 13 (15%) patients with non-DM1 had myotonic discharges. There was a statistically significant difference in the incidence rates across the groups (P=0.003). In this study, we also encountered three siblings with DM1. We observed myotonia and muscle weakness in the twins, indicating there is a possibility of anticipation being seen in their grandchildren in the future.
Conclusion: Genetic counseling is crucial for understanding disease variability, aiding in better DM1 management.

Метаплазме представљају фигуре које делују на звучни и графички аспект речи, те мењају утврђени облик речи као скупа фонема или слогова. Анализа српског превода који је начинио Данило Киш, а који до данас остаје једини превод овог дела на српски језик, полази од теорије еквиваленције Питера Њумарка, посебно са становишта његових појмова семантичког превода (semantic translation) и еквивалентног ефекта (equivalent effect). Резултати анализе посматрани су са аспекта теоријских начела Антоана Бермана и Валтера Бенјамина о дословном превођењу, како би се утврдило у којој мери је могућ, али и остварен принцип дословног превођења. Резултати традуктолошке анализе најпре потврђују да је преводилачки метод прилагођен експресивној функцији текста, те да се ради о семантичком преводу, који, истовремено, остварује еквивалентни ефекат. Принцип дословног превођења препознат је у примењивању истог стилског поступка на дословно преведен основни текст.

Radi veće preglednosti članke smo razvrstali po decenijama, tačnije u dva perioda: od 1961. do 1971. godine i od 1971. do 1981. godine.
IDEOLOGIJA STANDARDNOG JEZIKA: POJAM, NEGATIVNE POSLEDICE I DUŽNOST LINGVISTA
Authors: Deretić Nastasja M.
Published: December 2024

Ovaj rad prikazuje pojam ideologije standardnog jezika, opisuje njene karakteristike, kao i njen negativni uticaj na pojedince i društvo u celini. Prvi deo teži da sažeto objasni postupak standardizacije jezika, a zatim i proces mistifikacije tog postupka oličen u pojavama kao što su preskriptivizam i purizam u jeziku, koji pod okriljem ideologije standardnog jezika prerastaju u „zdravorazumski“ stav o tome kako jezik (treba da) funkcioniše. Nakon toga se ukazuje na različite posledice ove ideologije: jezičku anksioznost i šizoglosiju kod govornika, jezičko nasilje među govornicima i konačno – isključivanje govornika iz javnog diskursa. U poslednjem delu rada upućuje se poziv na odgovornost lingvista i njihov etički angažman u procesu ublažavanja i prevazilaženja štetnih posledica ideologije standardnog jezika.
TUMAČENJE BAJKE PRINC DRAGOLJUB ŽANE MARI LEPRENS DE BOMON PREMA AKTANCIJALNOM MODELU

Oslanjajući se na Propova (Пропп) istraživanja strukture narodnih bajki, tokom šezdesetih godina XX veka Gremas (Greimas) razvija svoj aktancijalni model, koji ima za cilj dubinsku analizu određenog teksta, a zasnovan je na prepoznavanju šest nepromenljivih činilaca radnje – aktanata. Proširujući saznanja o odnosima među aktantima, An Ibersfeld (Anne Ubersfeld) primenjuje Gremasov aktancijalni model na dramske tekstove (ostavljajući mogućnost primene i na nedramske tekstove). Predmet ovog rada jeste analiza bajke Princ Dragoljub (Le Prince Charmant) francuske spisateljice i pedagoškinje iz doba prosvetiteljstva, Žane Mari Leprens de Bomon (Jeanne-Marie Leprince de Beaumont). Princ Dragoljub je moralizatorska bajka izdvojena iz autorkinog najpoznatijeg dela – Zabavnika za decu (Le Magasin des enfants), objavljenog 1756. godine. Kroz tumačenje ove bajke prema aktancijalnom modelu An Ibersfeld, u ovom radu prepoznaju se i razvrstavaju aktanti u šest utvrđenih polja (subjekat, objekat, pošiljalac (adresant), primalac (adresat), pomoćnik i protivnik), nakon čega se analizira nekoliko mogućih aktancijalnih modela.
УМЕТНОСТ ИСПОД ВЕШАЛА: ВИЈОН, РЕМБО И ДАВИЧО КАО АЛТЕРНАТИВНИ ГЛАСОВИ ЕПОХЕ

Када је реч о стваралаштву Франсоа Вијона, Артура Рембоа и Оскара Давича, аспект који им је заједнички не само у песничком већ и културолошком смислу јесте њи- хов однос према друштвеној пракси која је колико поетичка толико и политичка. Сродни са тим су проблеми литерарног језика/израза, семантике форме, а тиме и, више филозоф- ско питање, однос мисли (свести) и језика. Учествујући директно у социјалним преви- рањима својих епоха, и спајајући изразито иноваторски књижевни израз са својом субвер- зивном оријентацијом у оквиру тих дешавања, тројица песника представљају својеврсну песничку вертикалу. У раду ћемо се, компаративном анализом, пре свега бавити делом Оскара Давича у светлу двојице старијих песника као његових историјских аналогона или претходника. То би се учинило кроз три основна аспекта: поменуто питање језика, свести и књижевне форме; потом, питање концепције тела и телесног; и најзад, као спој претходна два аспекта, питање актуелне друштвене стварности и положаја песничког „ја“ у њиховом стваралаштву.

Lack of coordination of a person's movements is caused by the lack of optimal kinesthetic intelligence provided from an early age. This research is aimed at stimulating and developing children's kinesthetic intelligence. The type of research used is quantitative research with a Quasi Experimental research method and a Posttest Only Control Design design with the samples used, namely children in classes B1 and B2 consisting of experimental classes and control classes using purposive sampling techniques. The data collection techniques used are observation and documentation. The analysis technique for this research uses the SPPS version 26 for Windows program. Prerequisite test analysis was carried out to calculate normality using the Kolmogorov-Smirnov test, calculating homogeneity using the statistical Lavene test on both samples (Classes B1 and B2) and hypothesis testing analysis using the t test with the Independent sample T-test formula. Based on the results of calculations with the help of the SPPS program using a significance level of 5%, the hypothesis calculation results were obtained with a confidence level of 95%, tcount was 20.259, greater than ttable, namely 2.036 (20.259 > 2.036) with Sig. (2-tailed) of 0.000 where smaller than 0.05 (0.000 < 0.05) means that H0 is rejected and Ha is accepted. The conclusion is that there is an influence of playing gymnastics on children's kinesthetic intelligence at Harniatun Arrazzaq Kindergarten in Bandar Lampung.

Despite the high knowledge of the diagnosis and treatment of Mallory-Weiss syndrome, this pathology is still a rather severe and dangerous complication, and according to the world literature, in recent years, the incidence of Mallory-Weiss syndrome has remained at a fairly high level, and mortality is 13-17 % among patients with gastrointestinal bleeding. Research purpose : to study the features of treatment of patients with Mallory-Weiss syndrome admitted to the surgical department of the Tambov City Clinical Hospital. Materials and methods . We analyzed 27 case histories of patients with Mallory-Weiss syndrome treated from 2021 to 2022. We divided all patients into 3 groups in accordance with the classification of the severity of blood loss according to A.I. Gorbashko: patients with mild blood loss amounted to 17 people (63 %) of the total number of subjects, with moderate and severe severity - 5 people each (18.5 %). Conclusions . As a result of the study, we established that the leading cause of bleeding is alcohol withdrawal syndrome (70 % of cases studied). In second place was the exacerbation of existing diseases of the gastrointestinal tract (peptic or duodenal ulcer, erosive processes of the esophagus, etc.). In most cases (82.5 %), in patients with mild to moderate severity, conservative therapy with positive outcome dynamics is successfully used to establish the status of stopped bleeding and the absence of its recurrence. In severe concomitant diseases of the gastrointestinal tract and cardiovascular system, patients must be hospitalized in the intensive care unit, and with repeated ongoing bleeding, emergency laporotomy with closure of the defect and hemostasis is indicated. During the analysis of the most frequent locations of bleeding in Mallory-Weiss syndrome, it became difficult to classify the affected areas. This is due to the wide range of terms used by physicians regarding the same localization. Based on this, we recommend introducing uniform terminology for describing the localizations of each part of the esophagus and stomach.

Currently, the problem of treating asthenic syndrome and cognitive disorders is quite relevant. In clinical practice, a patient with cognitive impairment poses a difficult task for doctors of various specialties in terms of diagnosis and selection of effective therapy. Timely detection and prescription of pathogenetically justified therapy is fundamentally important, since it contributes to the functional restoration of cerebral structures and prevents irreversible consequences. In recent years, the importance of differentiated and timely use of neuroprotective and metabolic drugs, which could contribute to the most effective result and cause the least side effects, has been increasingly discussed. Purpose : to study the effect of cytoflavin as an additional nootropic therapy at patients of a psychiatric clinic. Materials and methods : we studied the mechanism of action of the drug “Cytoflavin” and its effect on patients of the Tambov Psychiatric Clinical Hospital who are on outpatient and inpatient treatment with diseases such as organic mental disorders, chronic delusional disorders, affective mood disorders, mental retardation. Results . The research presents changes in cognitive function and asthenic status in psychiatric hospital patients. According to the results of our study, it turned out that cytoflavin therapy was more effective at patients with organic mental disorders. Conclusions . The obtained data and reliability analysis make it possible to conclude that it is advisable to use cytoflavin in treatment and rehabilitation programs for patients with asthenic and cognitive disorders.

Dialogando con el trabajo de otros investigadores, el artículo estudia la intervención de la petrolera estadounidense Esso en la esfera cultural y artística de Colombia durante la Guerra Fría. En particular, se explora la posibilidad de que algunas manifestaciones artísticas patrocinadas por la Esso hayan funcionado como un instrumento de diplomacia blanda (soft diplomacy) en las fases que precedieron y acompañaron el lanzamiento, en 1961, por parte del presidente estadounidense Kennedy, del ambicioso programa de ayudas económicas, políticas y sociales para Latinoamérica denominado Alianza para el Progreso. Cargado de supuestos anticomunistas y modernizadores, este programa tuvo en Colombia uno de sus principales receptores de ayuda.

História oral, memórias coletivas e identidade de classe em lutas pela terra na Baixada Fluminense
Authors: Bastos Gabriel Souza
Published: December 2024

Este artigo analisa a persistência de uma identidade camponesa de classe em uma área rural da Baixada Fluminense, manifestada pela história oral e reproduzida pela população local ao longo de décadas, por meio de concepções de filosofias espontâneas e economia moral, no que diz respeito aos usos da terra. Através de análises documentais, jornalísticas e de memória oral, por meio de entrevistas e interações com moradores da região em trabalho de campo, o artigo destaca continuidades e descontinuidades nas representações sociais da memória no que diz respeito a identidades sociais. Evidencia-se como essas memórias coletivas se fragmentaram, refletindo não só aspectos da mobilização política de entidades de trabalhadores rurais, mas também resquícios da repressão ocorrida durante o período ditatorial.
