In recent years, a large number of research of telecommunications traffic have been conducted. It was found that traffic has a number of specific properties that distinguish it from ordinary traffic. Namely: it has the properties of self-similarity, multifractality, long-term dependence and distribution of the amount of load coming from one source. At present, many other models of traffic with self-similarity properties and so on have been built in other researched works on this topic. Such models are investigated in this paper, which considers traffic in telecommunications networks, the probability of overflow traffic buffer. Statistical models are built to analyze traffic in telecommunications networks, in particular to research the probability of buffer overflow for communication networks. The article presents the results of the analysis of processes in telecommunication networks, in particular traffic; research of possibilities of representation of real processes in the form of random processes on the basis of use of statistical simulation model; the necessary mathematical and statistical models are selected and analyzed; software-implemented models using the Matlab environment; visual graphs for comparison of the received data are given; the analysis of the received models is carried out.

The effect of local wind on seismic noise near 1 Hz at the MELT site and in iceland
Authors: Wilcock William S. D. , Webb Spahr C. , Bjarnason Ingi Th.
Published: November 2022

The mantle electromagnetic and tomography (MELT) experiment on the east Pacific rise near 17°S was the first large teleseismic experiment on a midocean ridge. During the six-month deployment, no compressional arrivals were well recorded above 0.5 Hz. In comparison, the ICEMELT experiment in Iceland recorded compressional arrivals at 1-2 Hz from about 2 earthquakes per month. We compare noise spectra from the two experiments and show that this difference in detection is at least in part a result of noise. Near 1 Hz, seismic noise in the oceans is produced locally by wind-generated waves. At both experiment sites, 1-Hz noise levels are well correlated with local sea-surface-wind speeds derived from satellite observations. For a given wind speed, 1-Hz noise levels are about 10-20 dB lower in Iceland. At the MELT site, cross-correlations of wind speed with the logarithm of noise in a narrow-frequency band yield correlation coefficients exceeding 0.7 at frequencies between 0.4 Hz and 2 Hz. Noise levels at 1 Hz increase with wind by 1.3-1.4 dB per m/sec for wind speeds less than 10 m/sec. For the ICEMELT experiment, high correlation coefficients extend to markedly higher frequencies for coastal stations, and there is a 10-dB drop in 1-Hz noise levels 100-km inland. Noise levels increase by about 0.8 dB per m/sec. The strong correlation between wind speed and 1-Hz seismic noise provides justification for using satellite wind speed data to search for locations on the global spreading system where there is a better probability of recording high-frequency arrivals. The calmest sites are found on the northern east Pacific rise, near the equator in all oceans, and near 34° N and 22° S on the mid-Atlantic ridge.

Damage to specimen collections occurs in practically every herbarium across the world. Hence, some precautions must be taken, such as investigating the factors that cause specimen damage in their collections and evaluating their herbarium collection handling and usage policy. However, manual investigation of the causes of herbarium collection damage requires a lot of effort and time. Only a few studies have attempted to investigate the causes of herbarium collection damage. So far, the non-gaussian approach to detecting the causes of damage to herbarium specimens has not been studied before. This study attempted to explore the effect of species type, time, location, storage, and remounting status on the level of damage to herbarium specimens, especially those in the genus Excoecaria. Gaussian modeling is not good enough to model the counted data phenomenon (the amount of damage to herbarium specimens). Negative binomial regression (NBR) provides a better model when compared to generalized Poisson regression and ordinary Gaussian regression approaches. NBR detects non-uniformity in the storage process, causing damage to herbarium specimens. Natural damage to herbarium specimens is caused by differences in species and the origin of specimens.

Published: November 2022

Este artículo analiza el papel del derecho en las movilizaciones por la reparación, la restauración y el reconocimiento del legado de violencia y subdesarrollo económico producto del colonialismo, la esclavitud y el racismo en los estados miembros de la Comunidad Caribeña (CARICOM). Al enfatizar en las demandas de reparación y restitución presentadas por CARICOM contra diversos estados europeos, este artículo atiende los siguientes tres objetivos: 1) mostrar cómo los efectos de la violencia colonial son interpretados en la actualidad; 2) identificar quiénes son los actores más importantes y cuáles son los reclamos adelantados; 3) analizar los usos del derecho implementados por esta movilización y las posiciones jurídicas asumidas por los estados europeos que han sido demandados. Este artículo propone un análisis socio-jurídico de las movilizaciones jurídicas en el contexto postcolonial caribeño. Este análisis de las movilizaciones de CARICOM por la justicia y la reparación nos permitirá establecer un diálogo sobre el papel de los estados postcoloniales en los procesos de memorialización de la violencia colonial y sobre la posibilidad de la justicia decolonial en el contexto de los estados caribeños.

Authors: Niazkhani Abolfazl , Mohammadi Ahmad , Mashhadi Hamid , Mahmoudnia Fahimeh
Published: November 2022

Background and purpose: Nowadays, microalgae are considered as the third-generation technology for the production of biodiesels in nature. Chlorella vulgaris is one of the most widely used microalgae for commercial purposes. It is one of the best options for producing biodiesel from algae because of its abundance and flexibility in cultivation. The systems applied for the production of algae are facing high expenses. One way to decrease the cost is to obtain the optimal values for the various parameters of the culture medium for maximum growth in algae.Materials and methods: Therefore, in this study, the effect of parameters such as salinity, temperature, light intensity, light exposure time and acidity on cell density, biomass, lipid and biodiesel production was investigated.Results: As a result, the highest cell density of Chlorella vulgaris was observed at 26 °C, light intensity of 3500 lux, light exposure of 17 hours, salinity of 5 ppm and pH of 7.5. The highest production of biomass was at light intensity of 3000 lux, light exposure time of 14 hours, salinity of 5 ppm and pH of 9. The highest lipid production was observed at 26 °C, lightintensity of 4200 lux, light exposure time of 18 hours, salinity of 11 ppm and pH of 8. The highest biodiesel production was observed at 26 °C, light intensity of 4200 lux, light exposure time of 18 hours, salinity of 11 ppm and pH of 8.Conclusions: These types of algae, which maintain themselves against environmental and non-biological stresses, show high specimen ability and resistance to recombinant shapes.

Published: November 2022

SARS-CoV-2 causing COVID 19 disease has emerged as one of the most infectious pathogen known to humans, causing severe acute respiratory illness (SARI) along with MERS and Influenza A/H1N1. The proportion of asymptomatic and mild illness is significantly higher and a minimal proportion of individuals develop a severe disease. Albeit, more cases of COVID-19 are from India, but the data regarding clinical epidemiology of COVID-19 in India is very low. In this backdrop, the present study was aimed to evaluate the clinical/epidemiological characteristics and outcomes of asymptomatic vs. symptomatic COVID-19 patients.

All relevant clinical and demographic and epidemiological information was recorded over a period of one year From March 2020 to march 2021. A total of 217,665 samples from clinically suspected cases of COVID-19 were collected and using upper respiratory tract swabs. RT PCR assay was conducted according to the manufacturer's instructions for the detection of RNA from SARS-CoV-2 present in the nasal pharyngeal swabs of from the patients suspected of COVID-19.

Out of the total 217,665 samples, 133474 (61.3%) were males and 84,191 (38.7%) were females. Among the 24,009 (11%) tested positive cases for SARS-CoV-2 infection, 15,254 (63.5%) were males and 8755 (36.5%) were females. The age group between 30 – 39 years showed high positivity and the fever was the most common symptom. Among the positive cases 60% were asymptomatic and 40% were symptomatic. Male patients, patients above 60 years of age and with comorbid conditions were more symptomatic. Children with <10 years age and positive patients with age group of 10 -19 were asymptomatic.

In our study, theproportion of asymptomatic COVID-19 was higher with male preponderance. Thus the higher number of asymptomatic positive patients with increased chance of transmission is missed on symptom-based screening calls for adherence to preventive measures. Thus, effective measures must be taken among the asymptomatic cases to halt the transmission of disease, prevent death and alter the course of this epidemic.

Published: November 2022

The Rhesus (Rh) system is one of the most complex blood group systems in humans. In some individuals Rh D antigen show weaker expression on red cells. The aim of the study was to find out the prevalence of serologic weak D in north India and associated immunohematological problems.

Cell and serum grouping were performed on all sample with the help of Qwalys 2 & Qwalys 3 (Diagast, France). All Rh D negatives samples in routine blood grouping were subjected to serologic weak D testing with the help of Erythrocytes Magnetized (EM) Technology.

Total 65,407 whole blood donors were tested for blood grouping in the study period. Prevalence of serologic weak D phenotype in this study was 1.11% of Rh negative donors. The maximum number of serologic weak D phenotype were from B blood group, i.e. 13 (37.14%).

The prevalence of serologic weak D varies in different part of India as well as in the world. This study reported 1.11% prevalence of serologic weak D among Rh D negative blood donors. All serologic weak D positive individuals should give a blood group card showing their Rh D status as donor and recipient. Some European centers started routine RHD gene screening of first-time donors to eliminate the risk of Rh D sensitization. Molecular testing is very costly.For developing countries like India we required an affordable molecular testing technique to improve patient care or alternatively establish reference molecular laboratory for cost effectiveness.

Authors: Manouan Wedjers Max Robin , Karidioula Daouda , Kouassi Edouard Koffi , Aquoi Patrick Kouame , Boa David
Published: November 2022

This work was devoted to the formulation of thermodynamic properties of binary systems of molten salts by using an ionic model which requires three physical parameters for each salt : the crystal lattice energy, the latent heat of melting and the sum of the ionic radii. This formulation, whose adjustable parameters have been obtained by smoothing from the experimental mixing properties available in the literature, allowed us to calculate the molar enthalpies of mixing for twelve (12) binary systems of alkali nitrate and silver nitrate. The different results obtained show satisfactory general agreement between calculation and experiment with regression coefficients within the range 0.992 and 0.999 and relative uncertainties between experimental and calculated values of less than 6% throughout the compositional range for all systems studied. The present formulation more accurately determines the enthalpies of mixing of binary systems with a volume effect (without intermediate compounds) predominating over the chemical effect (formation of intermediate compounds) ; Furthermore, we were able to show that in binary systems of alkali nitrates based on lithium nitrate and sodium nitrate, the solutions are strictly regular and that the deviation from regularity increases as one goes down in the alkali metal family namely from lihium to caesium.

Published: November 2022

Background: Pineapple juice processing is an art of preservation, and the processing technologies play important role in pineapple juice quality. Therefore, this study aimed to explore the potential impacts of non-thermal processing methods on the physicochemical, bioactive, and microbiological properties of fresh pineapple juice.
Methods: Extracted juices were subjected to several non-thermal processes including microwave processing, vacuum evaporation, mild pasteurization, pulsed electric field, and ultra-sonication. Physicochemical properties including Total Soluble Solids (TSS), pH, titratable acidity, and color; Total Phenolic Content (TPC); Total Anthocyanin Content (TAC); antioxidant capacity; and microbiological properties were evaluated. Data were statistically analyzed by Minitab statistical software (version: 18.1).
Results: TSS, pH, acidity (%) of processed juices ranged from 11.03-12.03, 4.07-4.27, and 0.42-0.49, respectively. In terms of color properties both ultra-sonication and microwave processing showed the highest values of L (luminosity), a* (redness), and b* (yellow). The highest TPC was reported in ultra-sonication treatment 11.996±0.002 mg Gallic Acid Equivalents (GAE)/100 ml. The TAC varied from 0.179-0.235 mg Total Anthocyanin (TA)/100 ml, where ultra-sonication and mild pasteurization treatment yielded the highest and lowest contents, respectively.
Conclusion: Perfect phenolic content, antioxidant capacity, retention of anthocyanin content, and attractive color in pineapple juices when treated with non-thermal techniques.
Antibacterial Activity of Cell-Free Culture Supernatant of Bacterioci-nogenic Pediococcus pentosaceus IO1 against Staphylococcus aureus Inoculated in Fruit Juices
Authors: Adesina I.A. , Oluwafemi Y.D.
Published: November 2022

Background: Staphylococcus aureus is a major food-borne pathogen worldwide and a frequent contaminant of fruit juices. This study aimed to evaluate the antibacterial activity of bacteriocin-containing Cell-Free Culture Supernatants (CFCS) of Pediococcus pentosaceus IO1 against S. aureus inoculated in fruit juices, as well as their impact on the juice sensory attributes.
Methods: The orange and watermelon juice samples were treated with bacteriocin supernatant at different concentrations (1, 5, and 10% v/v) and the sensory attributes were evaluated using a 5-point hedonic scale and thereafter inoculated with a culture of S. aureus. Then, the inhibitory effect of bacteriocin-containing CFCS of P. pentosaceus IO1 against S. aureus in the fruit juices was evaluated by in situ and plate assays.
Results: The 10% (v/v) bacteriocin-containing CFCS exhibited the highest antibacterial activity, reducing S. aureuscounts in pasteurized orange and watermelon juices by 1.42 and 2.12 log Colony Forming Units (CFU)/ml, respectively, and by 1.03 and 0.88 log CFU/ml in unpasteurized orange and watermelon juices, respectively, compared to the control. The taste, colour, and overall acceptability of pasteurized orange and watermelon juices treated with 1% (v/v) bacteriocin supernatant and 0.1% (w/v) sodium benzoate were not significantly different (p=0.228) from those pasteurized orange and watermelon juices without preservative.
Conclusion: The bacteriocin produced by P. pentosaceus IO1 could be used as a natural preservative in fruit juices to control S. aureus.

Published: November 2022

A detecção de falhas em motores é um tópico de pesquisa muito ativo dentro da literatura, pois visa atender uma real demanda da indústria por proteção de seus equipamentos, possibilitando a redução dos tempos de parada e custos de reparo. Em especial, a falha de fuga à terra em rotores bobinados de motores síncronos apresenta taxa de falha relativamente elevada, uma vez que o enrolamento de rotor é exposto concomitantemente a ciclos de estresse elétricos, mecânicos e térmicos. Sua detecção é dependente do tipo de aterramento do sistema elétrico de potência, bem como, em sua forma iminente, ainda em estágio inicial, pode apresentar resistência significante. Dessa forma, o presente artigo apresenta uma solução simples que utiliza apenas um sensor extra para a detecção de fugas à terra em rotores síncronos alimentados por excitação estática tiristorizada. Tal solução foi implementada diretamente no controlador do conversor estático, sendo posta à prova com sucesso em motores síncronos (2.4MW/3.3kV) de uma linha de laminação a frio do grupo ArcelorMittal.

Objective. Analysis of literature data of modern neurosurgical techniques in the treatment of lumbar disc herniation; clarification of the features of surgical tactics and results during microsurgical, endoscopic methods and laser thermoplastic of the intervertebral disk. Methods. A retrospective analysis of the results of conventional microdiscectomy (228 cases), laser disc decompression (22 observations) and percutaneos endoscopic discectomy (4 observations) for lumbar disc herniation from 2016 to 2018. The results of surgical treatment was assessed according to the Oswestry Disability Index (ODI), Visual Analog Scale (VAS), modified MacNab criteria, and morphometric data of MRI and CT scans during the preoperative and postoperative periods, as well as 6 and 12 months after surgery. Results. The result of the study was a comparison of the literature data with those obtained in our clinic in the treatment of patients using all the indicated methods. On our material, we received confirmation of the feasibility and perspectivity of using minimally invasive methods in the treatment of lumbar disc herniation with low probability of recurrence and repeated treatment for pain. Also agree with the statement that the techniques have limited application, especially with instability in the VMS and multilevel lesion. Conclusion. Endoscopic discectomy, as well as laser disc decompression, are minimally invasive methods of treatment lumbar disc herniation, and have become an alternative to open lumbar microdiscectomy, as they allow minimizing surgical trauma, the effects of surgery, and quickly regress pain syndrome, contributing to early post-operative activation of the patient. A personalized approach in the treatment of lumbar disc herniation is based on the competent selection of patients and the clarification of a number of factors in determining.

The Competition for Cumania between Hungary and Bulgaria (1211–1247)
Authors: Madgearu Alexandru
Published: November 2022

Because the alliance between the Cumans and Bulgaria was a danger both for Hungary and the Latin Empire, it was preferable for Hungary to extend its domination over Cumania. The Teutonic knights were settled in south-eastern Transylvania in 1211 to defend it against the Cumans, who, after 1214, became enemies also for Bulgaria. Besides the few fortresses built in the Bârsa land, there is no certain proof for an expansion of the Teutonic Order outside the Carpathians, and by consecquence of the Hungarian kingdom, in the period before the Mongol invasion of 1241. After the departure of the Teutonic knights in 1225, Cumania became the target of the Dominican mission which was present since around 1221 in Terra Severin, a north-Danubian Bulgarian possession. The Cuman bishopric was established in 1227. The subjection of these Cumans made useless the preservation of the Hungarian-Bulgarian alliance closed in 1214, and the consequence was the annexation of Terra Severin by Hungary, sometimes between 1228 and 1232, as a Banat. The final act of the Hungarian expansion in Cumania was the introduction of the title of King of Cumania by Bela IV in 1236. The region where it was established the bishopric of Cumania continued to be under the influence of the Church of Tărnovo, even after the end of the domination of the Bulgarian state in this north-Danubian territory. In 1241, the Cuman bishopric was destroyed by the Mongol invasion. Because the Golden Horde domination did not extend west of Olt in the first years after 1242, Bela IV tried to regain positions by summoning the Hospitaller Knights in 1247. Terra Severin remained a part of the Hungarian kingdom, but the function of Ban was abandoned or suspended. One mission of the Hospitallers was to extend the Hungarian domination in Cumania, in the regions which were then conquered by the Mongols. The Mongol domination prevented the emergence of a Cuman kingdom in Moldavia, vassal of Hungary. Only the decline of the Golden Horde made possible a new penetration of the Hungarian kingdom in the former Cumania, in 1345. The former Cumania entered in the new states created during the 14th century by the Romanians liberated from the Hungarian domination, Wallachia and Moldavia.

Published: November 2022

Background: The soil fertility assessment is crucial for sustainable agriculture and plant yields. The knowledge of the trophic level of agricultural soil fertility is mandatory in order to define the development of food crops due to the lack of soil fertility assessment in this region and the decrease in crop yields. Methods: In this context, an investigation was carried out to study the fertility status of the Mansala-Kayikoro soils and some essential soil properties, such as pH, CEC, OM, EC etc. Ten soil samples were collected from farming areas and analyzed for macronutrients, micronutrients and essential soil physicochemical properties. Result: Soils of the Kayikoro area were highly acidic to slightly acidic in reaction with a low to high organic carbon (OC) content. According to the data, the cation exchange capacity (CEC) was deficient. The available macronutrients such as N, P and K content in the soils were found below the requirement of plant. The concentration of micronutrients such as iron, copper, manganese and zinc was slightly low in the analyzed samples.

Authors: Lam Vo Tran , Lan Nguyen Thi , Giang Pham Huong , Tien Le Thi Thuy
Published: November 2022

Background: Seawater intrusion causes many unfavourable effects on crops, especially rice, which is very sensitive to salt. Salinity stress reduces the growth and development of rice, thereby reducing the yield. This is an important issue affecting the food security of many countries in the world. This study focused on using oligochitosans to increase salinity tolerance and improve rice growth at the seedling stage. Methods: Dry and rice-sprouted seeds were treated with oligochitosan solutions of different molecular weights and concentrations and incubated in NaCl solution at a concentration of 0.6%. The salinity tolerance of rice seedlings was assessed through in vitro indices in the plants’ shoot length, number of leaves, number of roots (apical and lateral roots) and root length, fresh and dry weight, photosynthetic pigments, proline, total sugar and total protein. Result: Oligochitosan 5994 Da at a concentration of 75 ppm improved the growth of rice seedlings under salinity conditions. Oligochitosan 11126 Da at the concentration of 100 ppm improved the growth of rice seedlings under salinity stress in the investigation of dry seed treatment. The salinity tolerance of rice seedlings was observed through the increase of photosynthetic pigments, proline, and total sugar concentration and morphology.

Published: November 2022

Background: Fenugreek (Trigonella foenum-graecum L.) is one of the oldest spices crop of the world. It is the third largest seed spice in India after coriander and cumin. It is a Rabi season crop, mostly grown in sandy loam soil. The present study was carried out to get better information regarding GCV, PCV, heritability and genetic advance, pre requisite for formulating an effective breeding programme. Methods: Fifty-two accessions of fenugreek (Trigonella foenum-graecum L.) including four checks viz., (AFg-1, AFg-2, AFg-3 and RMt-1) were evaluated in augmented complete block design (ACBD) in Rabi 2021-2022 for nine quantitative traits. Analysis of variance for agro-morphological characters showed in significant differences among the studied accessions indicating existence of wide variability. Adjusted mean values were used for estimation of genetic variability parameters. Result: The high to medium magnitude of genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV), high heritability coupled with high genetic advance were expressed by traits viz., number of branches per plant, number of pods per plant seed yield per plant and test weight. On the basis of per se performance of fifty-six accessions including checks it is concluded that selection of number of branches per plant and number of pods per plant could be effective in EC510598 and AFg-1. Likewise effective selection could be made in IC0624520 for early maturing. For pod length, accession EC510631 and for seed yield per plant EC510737, EC510536 and AFg-1 could be efficiently utilized for improvement of respective trait in fenugreek.

Melanoma is one of the most aggressive skin cancers, however, its early detection can significantly increase probabilities to cure it. Unfortunately, it is one of the most difficult skin cancers to detect, its detection relies mainly on the dermatologist’s expertise and experience with Melanoma. This research deals with targeting most of the common Melanoma stains or spots that could potentially evolve to Melanoma skin cancer. Region-based Convolutional Neural Networks were used as the model to detect and segment images of the skin area of interest. The neural network model is focused on providing instance segmentation rather than only a boxbounding object detection. The Mask R-CNN model was implemented to provide a solution for small trained datasets scenarios. Two pipelines were implemented, the first one was with only the Region-Based Convolutional Neural Network and the other one was a combined pipeline with a first stage using Mask R-CNN and then getting the result to use as feedback in a second stage implementing Grabcut, which is another segmentation method based on graphic cuts. Results demonstrated through Dice Similarity Coefficient and Jaccard Index that Mask R-CNN alone performed better in proper segmentation than Mask R-CNN + Grabcut model. In both models’ results, variation was very small when the training dataset size changed between 160, 100, and 50 images. In both of the pipelines, the models were capable of running the segmentation correctly, which illustrates that focalization of the zone is possible with very small datasets and the potential use of automatic segmentation to assist in Melanoma detection.

Published: November 2022

The cooling system is one of the most important parts of a robot, a correct design allows it to increase its capacity while reducing the chances of a malfunction. In general, cooling systems for humanoid robots require special characteristics to not interfere with the optimal operation; aspects such as weight, size, materials, and positioning of this system are crucial for maximum efficiency. The current problem in this design is that the cooling system needs to maintain its power to perform tasks when lifting heavy weights without consequences such as reduced mobility of the joint, and therefore decrease the robot’s efficiency. In this paper, we studied, analyzed, and discarded existing options of electric motor actuators. Once the viable options were obtained, so we proceed to make a proper design, then was made a computational fluid dynamics study (CFD) to get heat extraction measurements as well as fluid velocity, essential to make the final decision, solving the initial problem.
Accelerating machine learning at the edge with approximate computing on FPGAs

Published: November 2022

Performing inference of complex machine learning (ML) algorithms at the edge is becoming important to unlink the system functionality from the cloud. However, the ML models increase complexity faster than the available hardware resources. This research aims to accelerate machine learning by offloading the computation to low-end FPGAs and using approximate computing techniques to optimise resource usage, taking advantage of the inaccurate nature of machine learning models. In this paper, we propose a generic matrix multiply-add processing element design, parameterised in datatype, matrix size, and data width. We evaluate the resource consumption and error behaviour while varying the matrix size and the data width given a fixed-point data type. We determine that the error scales with the matrix size, but it can be compensated by increasing the data width, posing a trade-off between data width and matrix size with respect to the error.

Published: November 2022

BACKGROUND: Perceptual-cognitive skill is a crucial component of expert performance in sport as expert athletes rely on the integration and processing of sensory information to execute complex actions. One of the topics of interest to skill acquisition researchers is therefore how the perceptual-cognitive system can be trained, and how that affects sport skill performance. One of the methods suggested to be able to aid in the training of perceptual-cognitive skill is restricted visual feedback training.  Recently, stroboscopic vision glasses have been proposed as a tool that can restrict visual feedback during sport training and may therefore provide a useful tool for training sport-specific skills.However, despite its use in practice, evidence for the beneficial effect of stroboscopic vision on sport-specific performance across youth athletes with a range of performance levels is currently lacking.
AIM: Therefore, this study aimed to investigate the effect of a four-week soccer training program with (experimental group) or without (control group) stroboscopic vision on the dribbling performance of relatively fast and slow dribblers.
METHOD: To measure dribbling performance, this study used the Ugent Soccer dribbling task.
RESULTS: A Repeated Measures MANOVA revealed that four weeks of stroboscopic vision training did not improve soccer dribbling skill measured through the time taken to complete the dribbling task as well as the number of touches of the ball while dribbling.
CONCLUSION: While stroboscopic vision can likely lead to short term changes in perceptual-cognitive skill, it is likely not related to persistent changes in soccer dribbling performance in youth soccer players.
O potencial gastronômico e a redução da sociobiodiversidade
Authors: Ferreira Talitha Alessandra
Published: November 2022

Este artigo reúne notas a partir de uma pesquisa em andamento, de um trabalho de campo impedido, e do fracasso do Projeto Baunilha do Cerrado, desenvolvido entre 2015 e 2019 no território e comunidade Kalunga pelo Instituto Atá, do chef Alex Atala. O último caso ficou especialmente marcado pela denúncia das tentativas de registro de uma marca para as baunilhas à revelia da comunidade. Tais fatos nos levaram a repensar e a questionar as ações de valorização de ingredientes provenientes da sociobiodiversidade por parte da gastronomia brasileira, incluindo os discursos de seus representantes quanto a necessidade de descolonizá-la. Após retomarmos alguns dados da pesquisa, faremos a inferência que o modo como essa valorização tem se construído pode tornar a busca por ingredientes, como as baunilhas nativas, tanto predatória quanto redutora da sociobiodiversidade e sua importância.

Published: November 2022

Latar Belakang: Tingkat literasi tentang gizi ialah kemampuan dari mendapatkan hingga memahami informasi gizi dalam penentuan asupan keseharian. Literasi gizi yang dimiliki dapat mempengaruhi pola prilaku remaja dalam pemilihan makanan keseharian. Masalah gizi pada remaja pada skala nasional di Indonesia masih tergolong tinggi. Pada SMKN 4 Tanah Grogot terdapat 30,9% pelajar berstatus gizi tidak normal.
Tujuan: Penelitian ini bertujuan untuk melihat apakah terdapat hubungan antara tingkat literasi gizi dengan status gizi pada pelajar siswi di SMKN 4 Tanah Grogot.
Metode: Penelitian ini merupakan penelitian observasional analitik dengan desain case-control. Populasi penelitian ialah siswi di SMKN 4 Tanah Grogot kelas X dan XI berjumlah 169 siswi dengan jumlah sampel 34 kelompok kasus, dan 34 kelompok kontrol. Instrument yang digunakan berupa kuesioner untuk mengukut tingkat literasi gizi yaitu Health Literacy Measure for Adolescents (HELMA). Status gizi diukur dengan metode indeks massa tubuh menurut usia (IMT/U). Digunakan chi-square untuk melihat hubungan kedua variabel.
Hasil: Berdasarkan hasil penelitian distribusi responden dominan pada tingkat literasi gizi dengan katagori rendah pada kelompok kasus 20 responden (58,8%), dan pada kelompok kontrol 15 responden (41,1%). Hasil uji statistik menghasil hubungan yang negatif pada tingkat literasi gizi dengan status gizi (p=0,384).
Kesimpulan: Penelitian ini menunjukan tidak terdapat hubungan yang signifikan antara tingkat literasi gizi dengan status gizi siswi di SMKN 4 Tanah Grogot. Jadi semakin tinggi tingkat literasi gizi individu, tidak memberikan pengaruh terhadap status gizi.

Latar Belakang: Peningkatan kasus kecelakaan lalu lintas meningkat setiap tahunnya sejalan dengan peningkatan jumlah kendaraan bermotor. Kemajuan teknologi yang semakin pesat berdampak pada kemajuan bidang trasnportasi, sehingga tercipta aplikasi Ojek berbasis Online. Pada tahun 2020 tecatat sebanyak 2 juta driver online yang terdaftar pada satu perusahan dibidang transportasi. Kecelakaan pada pengemudi ojek online dapat disebabkan oleh beberapa faktor salah satunya adalah lama waktu kerja dan kelelahan subjektif. Pekerjaan sebagai ojek online mengharuskan pekerja bekerja pada lingkungan kerja yang panas, hal tersebut memicu terjadinya kelelahan pada pekerja yang mengakibatkan kejadian kecelakaan. Hal tersebut dapat diperparah dengan lama waktu kerja lebih dari delapan jam sehari dan tidak disertai istirahat cukup.
Tujuan: Mengetahui kuat hubungan antara waktu kerja dan kelelahan subjektif dengan kejadian kecelakaan pada pengemudi ojek online.
Metode: Penelitian ini berjenis observasional analitik dengan rancang bangun cross-sectional. Subjek penelitian adalah pengemudi ojek online sepeda motor di wilayah Kabupaten Sidoarjo sebanyak 110 responden. Variabel bebas dalam penelitian ini adalah waktu kerja dan kelelahan subjektif sedangkan untuk variabel terikat yaitu kejadian kecelakaan.  
Hasil: Hubungan antar variabel diukur menggunakan uji Cramers V dan Coeficient Contingensi. Hasil analisis menunjukan terdapat hubungan yang positif dan kuat hubungan lemah durasi kerja (CI=0,209), sedangkan terdapat hubungan yang cukup kuat dengan arah positif untuk kelelahan subjektif (r=0,326) dengan kejadian kecelakaan pada pengemudi ojek online.
Kesimpulan: Hasil analisis menunjukan terdapat hubungan yang lemah antara waktu kerja dengan kejadian kecelakaan pada pengemudi ojek online, sedangkan terdapat hubungan yang cukup kuat antara kelelahan subjektif dengan kecelakaan. Dari hasil analisis data arah hubungan kedua variabel independen adalah positif artinya semakin lama waktu kerja akan menyebabkan peningkatan kelelahan dan kejadian kecelakaan kerja.
