As a result, a difference in the temporal metabolic behavior of patients and disease-free subjects was observed
DIEP flap perforator mapping by infrared thermography: state of the art and researchprogression
Authors: Steenackers Gunther , Verstockt Jan , Verspeek Simon , Tjalma Wiebren , Thiessen Filip
Published: March 2023

Dynamic infrared thermography (DIRT) has been used to locate perforating vessels and to assist in reconstructive breast surgery. Qualitative information on the perforating vessels is obtained by analyzing the rate and pattern of rewarming of hot spots which are easily registered with an infrared camera. Thermal measurements are made before and during surgery and are compared with the CT images available before the operation. The thermal images can provide the individual influence of each perforator on the flap, as well as the dimensions of the perfused area. It will be investigated if the thermal image sequence locating the different dominant perforators will prove to be a useful tool for reconstructive DIEP-flap surgery
Performance analysis of a microbolometer camera with and without Peltier tempera-ture stabilizer
Authors: Felczak M , Sosnowski T , Kastek M , Strąkowski R , Stępień J , Więcek B
Published: March 2023

The article presents thermal modelling of a microbolometer detector inside the FPA (Focal Plane Array) camera.This modelling assumes heat transfer from/to the bolometer matrix through the multilayer structure. The Peltier cooler is one of the layer which enables the equalization and stabilization of the temperature below the FPA. The presented model allows to simulate the heat transfer by radiation between the matrix and an object and the impact of Peltier device on the FPAtemperature. The parasitic radiation heat transfer between the detector and surrounding objects resulting in the non-uniformity of the generated signal is neglected. The model can estimate the performance deterioration of a microbolometer camera due to the non-ideal stabilization of the temperature by the Peltier cel
Thermographic crack detection by liquid gas in materials with low emissivity
Authors: Lugin S , Netzelmann U
Published: March 2023

A new approach for detection of cracks in metals with low emissivity was investigated. Liquid gas is sprayed in a linear movement across the test object. The gas propagates into cracks open to the surface by capillary effects and by the pressure of spraying.This causes cooling and subsequent warming up. It was found that the time profiles of the temperature close to the crack have characteristic properties which are different from the time profiles of a pure surface distribution of the emissivity. Cracks of different depth were investigated in aluminium and steel. An advantage of the technique compared to liquid penetrant testing is the residual-free evaporation of the gas that allows testing in a single step

Authors: Urbaś Sebastian , Więcek Piotr , Więcek Bogusław
Published: March 2023

The article describes an innovative concept of a single-pixel thermal camera based on compressing sensing and deep learning image reconstruction. The proposed approach uses a deep learning network to reconstruct an image from sparse data. The network architecture and preliminary results for various compression ratios are presented. Compressed data was obtained using random and deterministic spatial modulation of thermal images. In this research the modulation was realized from original thermal images by software means. The results presented in this paper were obtained for low-resolution 80x80infrared images
Methods of improving the detection of defects in aramid fiber-reinforced composites in non-destructive testing by pulsed thermography
Authors: Swiderski W , Strag M
Published: March 2023

This paper presents a comparison of the effectiveness of the non-destructive pulsed thermography method supported by image analysis methods in detecting a very thin defect inside the structure of aramid fiber-reinforced composite. The technology of making the composite was the same as in the production of composite helmets. For comparison, the result obtained using the X-ray method is also presented. The obtained results show the possibility of a significant improvement in the efficiency of the detection of defects that are not clearly identifiable in the source sequence of thermograms
Impact of Temperature on Resonant Tank Components in LLC Resonant SMPS
Authors: Kasikowski R , Więcek B
Published: March 2023

LLC resonant topology contains a resonant tank consisting essentially of three components, namely the primary inductance of a transformer, a resonant inductance and a resonant capacitor. The operating frequency of the LLC converter is finely tuned to match the resonant frequency of the resonant inductance and capacitor, at which point electric current through the tank is, effectively, sinusoidal. The parameters of the resonant tank are temperature dependent and therefore changes in the capacitance and inductance of the resonant components, and, by extension, in the resonant frequency, occur. This results in the distortion of the current, and the efficiency of power conversion is affected. Herein, IR thermography is utilized to determine the steady-state operating temperature of LLC resonant tank components and hence the impact of temperature on the resonant frequency and operation of LLC SMPSs (switch-mode power supplies) can be ascertained
Contactless temperature field measurements in infrared semi-transparent materials using thermotransmittance imaging
Authors: Bourges C , Chevalier S , Sommier A , Maire J , Pradere C , Dilhaire S
Published: March 2023

Temperature field measurements need to be performed in many research areas to ensure an accurate control of numerous systems, such as in material sciences or biology. However, for infrared semi-transparent objects, like living cells or semiconductors, infrared thermography is not well-suited.To address this purpose, we used the thermal dependence of material transparency to image temperature fields. This thermotransmittance approach enables contactless and absolute temperature field measurements. This work introduces the calibration procedure of the thermotransmittance coefficient, and its use to image transient absolute temperature field
Monitoring Drosophila melanogasterthermogenesis by Infrared Thermography
Authors: Szramel J. M , Costa R , Ferrarini G , Bison P
Published: March 2023

Larvae of the poikilotherm insect Drosophila melanogaster reared at 23°C and switched to lower temperatures (i.e. 10°C)for over an hour are warmer than the surrounding medium. This is likely to be related to uncoupled respiration, resulting in thermogenesis. Indeed, silencing of the uncoupling protein UCP4C by suitable genetic manipulations significantly reduces larval thermogenesis.Measurement of temperature in wild-type, knock-down and knock-out larvae(positioned on a Thermal Controller maintaining surrounding average temperature constant)is performed by Infrared Thermography
Discrete Trigonometric Transform Thermography for Defect Detection in Composites
Authors: Lasso-Martinez I , Loaiza-Correa H , Restrepo-Giron A
Published: March 2023

Images obtained with Pulsed Thermography (PT) are often affected by noise and non-uniform heating. Therefore, numerous advanced signal processing methods have been proposed to solve these problems and thus improve the defects detection that are below the surface of materials. Some of these techniques are Principal Component Thermography (PCT), High-Order Statistics (HOS), Thermographic Signal Reconstruction (TSR) –and its first and second derivatives–. However, none of these methods is based on the law of conservation of energy of a signal (i.e., each image or thermogram) between space and frequency domains. With this approach, we developed an algorithm to detect defects in Carbon Fiber Reinforced Plastic (CFRP) composites. To do this we evaluated four types of Discrete Cosine Transforms(DCTs):DCT-1, DCT-2, DCT-3,DCT-4; and four types of Discrete Sine Transforms(DSTs): DST-1, DST-2, DST-3,DST-4.Comparison between results of the Contrast-to-Noise Ratio (CNR) metric shows that if the proposed algorithm uses DCT-1, then it outperforms the second derivative of the TSR. Furthermore, this method is robust against changes in shape or non-uniform heating centers.To our knowledge, the potential of these transforms for use in pulsed thermography has never before been evaluated
Temperature determination by thermography: emissivity measurement versus estimation algorithms
Authors: Camiruaga I , Fuente R , Gabirondo J , Sainz-Menchon M , Echániz T , López G A
Published: March 2023

Non-contact temperature measurement is very important for the control and inspection in different sectors of industry involving harsh environments, and an accurate measurement depends crucially on the emissivity determination. This work compares two possible methodologies to obtain accurate temperatures. Firstly, the emissivity is rigorously characterised in the laboratory and later used to correct the thermographic images. Secondly, by means of the so-called TES algorithms, approximations of both temperature and emissivity are obtained. Finally, both results are compared and the accuracy obtained together with the operational cost of the two processes and its readiness for industrial implementation are discussed
Radiometric Data Estimation using Thermogram and Comparison to the Data Provided by the Camera
Authors: Vdovjak K , Maric P , Balen J , Glavas H
Published: March 2023

Fire causes many casualties, as well as material damage and thus prevention and early fire detection, are important. There are many existing solutions that can detect anomalies after other visible symptoms which is already too late. By using infrared thermal(IRT) cameras anomalies can be detected in the early stage and thus potential catastrophes can be prevented. For the successful development and implementation of the anomaly detection algorithm, detailed spatial radiometric data is necessary. Most IRT camera manufacturers provide full radiometric data through their software which is very limited. In this paper, we estimate radiometric data using only the pixel intensity of the thermogram and temperature boundaries. Estimated data is further compared to the data provided by the camera manufacturer to validate our findings

Authors: Groz M M , Sommier A , Abisset-Chavanne E , Pradère C
Published: March 2023

A super-resolution method based on laser Flying Spot technique and InfraRed (IR) thermography is proposed. The thermal resolution given by an IR camera is limited by the pixel dimensions of the camera. The objective of this work is to achieve a better resolution through the displacement of a laser spot that is smaller than the pixel. The study of the thermal response and the knowledge of the laser displacement inside the camera pixels enable a first step toward the thermal super-resolution. The methodology of this technique and a first numerical example are presented in this paper

A combined treatment system of O3/UV oxidation and activated carbon adsorption: emerging contaminants in hospital wastewater
Authors: Nabavi Erfan , Pourrostami Niavol Kasra , Dezvareh Ghorban Ali , Khodadadi Darban Ahmad
Published: March 2023

Researchers have recently focused their attention on emerging contaminants (ECs) in wastewater because they pose serious health and environmental risks. Because ECs are persistent in the environment and have the ability to disrupt the physiology of target receptors, they have been labeled as contaminants of recent environmental concern. For removing various ECs, a variety of treatment technologies have been developed, including biological, chemical, and physical methods. However, no single technology can currently effectively remove ECs, whereas hybrid systems have consistently proven to be more effective. Furthermore, the majority of existing technologies are energy and resource intensive, as well as expensive to maintain and operate. Furthermore, the majority of advanced treatment technologies that have been proposed have yet to be evaluated for large-scale feasibility. Some ECs, particularly pharmaceuticals and pesticides, were found to be significantly removed using a hybrid technique that included ozone/UV and granular activated carbon (GAC). Besides, the removal of effluent parameters (TDS, COD, TOC) was enhanced through the GAC surface oxidization as a catalyst with NaOH before the process and by ozone within the procedure as well.
Evaluation of a novel porous antimicrobial media for industrial and HVAC water biocontrol
Authors: Blanford William James , O'Mullan Gregory D.
Published: March 2023

A novel treatment method, consisting of pea-gravel with a marine coating supplemented with alkyldimethylbenzylammonium chloride (ADBAC or benzalkonium chloride), has been examined for its antimicrobial performance and coating stability in aqueous environments. Initial column studies examining the porous media's ability to reduce bacterial loads in heating, ventilation, and air conditioning (HVAC) water found average reductions of 94% from pre-flush levels (106 colony forming unit (CFU)/mL) when assessed with R2A spread plates and 83% reductions with SimPlates. There was no observed statistical difference between the average of pre- and post-flush waters from four tests of the media without ADBAC. Taxonomic identification, by 16S rRNA gene sequencing, of colonies drawn from pre- and post-ABDAC R2A plates showed similarities with taxa observed in high frequency from prior cultivation-independent surveys of other cooling tower systems. With this proof of concept, two versions of the media were evaluated for potential coating components released during aqueous exposure. Neither released measurable volatile organic compounds (VOC) components, but one did release bisphenol A and ABDAC compounds. Subsequent column tests of the more durable coating were conducted using cultures of interest in industrial water and demonstrated significant reductions in neutralized post-column Enterococcus faecalis samples and near complete loss of Legionella pneumophila in non-neutralized fluids, but lower reductions in Pseudomonas aeruginosa.

Published: March 2023

Based on data from the Tabanan Regency Central Bureau of Statistics in 2020 administratively the Tabanan Regency area is 839.33 km2, consisting of 133 villages and 816 official banjars, with a population of 448,000 people. Tabanan Regency is one of the regencies in Bali, where the topographical conditions of the existing villages are mostly in remote areas, so they often experience difficulties with clean water distribution problems. For the current condition, the provision of clean water in Tabanan Regency is provided by PDAM (Local Water Company) through the use of springs, ground water and river water, in addition to several areas the water supply is carried out through Pamsimas (Community-Based Drinking Water and Sanitation Provision). Currently Pamsimas Tabanan Regency is divided into 9 service coverage areas for people in rural areas. In general, the condition of drinking water services presents the main problem, namely that not all areas are accessed by adequate water services. This problem is mainly caused by various obstacles such as limited water resources, limited infrastructure and topographical conditions.

Authors: Dewantari Regiana Yoshika , Suparta Nyoman , Putri Budi Rahayu Tanama
Published: March 2023

This study aims to analyze factors such as broiler chicken population, DOC prices, feed prices and drug prices on boiler chicken meat supply, and population, per capita income, boiler chicken meat prices, tourist visits and religious holidays to demand boiler chicken meat in Bali Province. The research method used is multiple linear regression analysis with the help of the SPSS program and trend analysis. Used 2 dependent variables and 9 independent variables. The data used in this study are primary data obtained from interviews with 100 respondents, while secondary data is obtained from annual data from 2009 to 2019. The results of the study concluded that the broiler chicken population, DOC prices, feed prices and drug prices had no effect on the supply of boiler chicken meat at the 95% confidence level and R2 of 0.641. This is because most breeders have partnerships with companies. Meanwhile, partially the demand for boiler chicken meat is determined by the population with a coefficient of 0.045 at 95% confidence. This shows that the increase in population is directly proportional to the consumption of broiler chicken meat. While other variables do not affect the demand for broiler chicken in Bali Province.
THE PERCEPTION OF SMALLHOLDER FARMERS TOWARD MICRO-INSURANCE AS A RISK COPING STRATEGY IN ZIMBABWE
Authors: Maireva Chrispen
Published: March 2023

Microinsurance is an important risk mitigation strategy in smallholder farmers’ agricultural enterprises that are faced with intensifying climate change and unpredictability. This study analysed the perceptions of smallholder tobacco farmers in Zimbabwe’s tobacco-growing regions of the Mashonaland Provinces towards microinsurance as a risk coping strategy given the risks of hailstorms, droughts, and long-dry spells in the rainy season. A qualitative phenomenological study was conducted with 13 purposively selected small-scale tobacco farmers. The study employed unstructured interviews to collect data from the participants. The findings of the study suggest that smallholder farmers have a positive perception of microinsurance, against the general view that they have a negative attitude. The study found that other risks with which smallholder farmers are faced and their immediate risk response, tolerance and disposition may have a distorting effect on the smallholder farmers’ perceptions and attitude towards microinsurance. It was further found that the perception of the smallholder farmers was also influenced by whether the farmers had other sources of income, whether they previously had experienced crop losses due to weather-induced risks and the general level of education of the smallholder farmer. It was also found that most of the micro-insurance services offered were mainly supply-side driven rather than demand-side driven and as a result, most of the products were not farmer-centric. New product development, farmer-centric insurance service offerings and general farmer sensitisation on the need for microinsurance were recommended.

Limited studies exist on the commitment of members to cooperative societies. Therefore, the study sought to measure perceptions of membership and the drivers of membership commitment of cocoa farmers' cooperative societies in the Atwima Mponua District of Ashanti Region, Ghana. Data was collected from a sample of 400 cocoa farmers through a multi-stage sampling technique. Descriptive statistics (mean and standard deviation) and inferential statistics (binary logit regression) were used in analyzing the data. Results show that cocoa farmers agree that they benefit from the cooperative and they appreciate the management, marketing and business, internal dynamics and public interest of their cooperatives. The study also discovered that farm age, access to extension service, farming experience, farmer status, cooperative benefits and internal dynamics are critical to obtaining commitment in cooperative societies. The study shows the need for the Ghana Cocoa Board to improve farmers’ access to extension services so as to improve their commitment in cooperative societies. Cooperative organizations are encouraged to consider the perceptions of the cocoa farmers and their socio-economic characteristics in order to elicit the desired commitment.

Published: March 2023

The concept of ecology-based tourism or ecotourism is the main attraction for tourists. This study was conducted to determine the attributes of superior ecotourism at resorts based on consumer preferences using the UGC (User Generated Content) approach. This study was use a non-probability sampling approach and the data analysis technique was the Jaccard Score, Z-Score and PCA rankings. The results show that ecotourism attributes that are consumer preferences based on UGC include natural beauty, accessibility, atmosphere, food and beverages, and service. In addition, the ranking of superior ecotourism attributes based on consumer preferences with a jaccard score coefficient from each resort, has a different rating. This rating also applies to the results of the binomial z-score test analysis which shows the level of consumer satisfaction with these attributes. Based on the PCA analysis, it was found that the resort hotel that has the potential to compete is between Legian and Oberoi. Resorts that have competitive potential are able to improve performance based on two main components formed from the PCA analysis, namely basic and advanced offers. The greater value of this coefficient means that the attribute has a large effect on improving performance and has an effect on resort decision making.

Older Adults, the “Social Admission,” and Nonspecific Complaints in the Emergency Department: Protocol for a Scoping Review
Authors: Furlong Kayla Rose , O'Donnell Kathleen , Farrell Alison , Mercer Susan , Norman Paul , Parsons Michael , Patey Christopher
Published: March 2023

Background

Older adults have a higher visit rate and poorer health outcomes in the emergency department (ED) compared to their younger counterparts. Older adults are more likely to require additional resources and hospital admission. The nonspecific, atypical, and complex nature of disease presentation in older adults challenges current ED triage systems. Acute illness in older adults is often missed or commonly disguised in the ED as a social or functional issue. If diagnostic clarity is lacking or safe discharge from the ED is not feasible, then older adults may be labelled a “social admission” (or another synonymous term), often leading to negative health consequences.

Objective

This scoping review aims to describe and synthesize the available evidence on patient characteristics, adverse events, and health outcomes for older adults labelled as “social admission” (and other synonymously used terms), as well as those with nonacute or nonspecific complaints in the ED or hospital setting.

Methods

A literature search of MEDLINE, Embase, Scopus, PsycINFO, and CINAHL was completed. Relevant reference lists were screened. Data have been managed using EndNote software and the Covidence web application. Original data have been included if patients are aged ≥65 years and are considered a “social admission” (or other synonymously used term) or if they present to the ED with a nonacute or nonspecific complaint. Two review team members have reviewed titles and abstracts and will review full-text articles. Disagreements are resolved by consensus or in discussion with a third reviewer. This review does not require research ethics approval.

Results

As of January 2023, we have completed the title and abstract screening and have started the full-text screening. Some remaining full-text articles are being retrieved and/or translated. We are extracting data from included studies. Data will be presented in a narrative and descriptive manner, summarizing key concepts, patient characteristics, and health outcomes of patients labelled as a “social admission” (and other synonymously used terms) and of those with nonacute and nonspecific complaints. We expect the first results for publication in Spring 2023.

Conclusions

Acute illness in the older adult is not always easily identified. We hope to better understand patient characteristics, adverse events, and health outcomes of older adults labelled as a “social admission,” as well as those with nonacute or nonspecific complaints. We aim to identify priorities for future research and identify knowledge gaps that may inform health care providers caring for these vulnerable patients.

LIPID AND SURFACTANT-BASED PHYTOFORMULATION FOR AMELIORATION OF INFLAMMATION
Authors: RAUT ROOPAM , SHAJI JESSY
Published: March 2023

Objective: Observations from traditional medicine and findings of modern science recommend use of curcuminoids and piperine in inflammatory ailments such as rheumatoid arthritis. Therapeutic potential of these phytoconstituents cannot be exploited to the maximum extent because of poor solubility and low bioavailability. The objective of this study was to overcome these challenges and harness the potential of these phytoconstituents by developing lipid and surfactant-based formulations. Methods: A microemulsion was prepared by selecting lipids, surfactants and cosurfactants on the basis of the solubility and stability of phytoconstituents. It was further converted into a transparent gel for topical application. The phytoformulation was characterized by physicochemical tests. Its hemocompatibility and irritation potential was determined. Further phytoformulation was studied in RAW 264.7 cells for cell internalization and antiarthritic potential was investigated in Complete Freund’s Adjuvant (CFA) induced arthritic rats. The disease progression was recorded. At the end of the study hematological, biochemical and oxidative stress parameters were measured. Results: A stable phytoformulation containing 0.75% w/w curcuminoids and 0.25% w/w piperine was developed. At the end of 24 hours, the amount of curcuminoids and piperine permeated through the skin from phytoformulation was 4.38 and 1.38 times that of the oil. It had good hemocompatibility and poor irritation potential. Internalization of phytoformulation in RAW 264.7 cells was concentration dependent. There were significant changes in rats due to disease induction by CFA and results indicated regression of the disease progress due to phytoformulation. Conclusion: Lipid and surfactant-based formulation improved solubility and permeability of phytoconstituents. The developed phytoformulation could recover inflammatory changes in rats and it can be further studied in human beings.

Abstract: The usage of the Internet has been growing rapidly, and in the field of natural language processing (NLP), sentiment analysis has become one of the most popular techniques. Using sentiment analysis, the emotional tone behind a body of text can be mined effectively for different occasions. Instagram has become a popular platform for people to buy and sell online. Nonetheless, some studies have found that frauds occurred as a result of buying and selling on the platform, such as when product quantity and specifications differed from what was claimed, a defective product was received, and other frauds involved Instagram sellers. Hence, trust is vital when customers are engaged in S-Commerce activities on Instagram, and there is a need for a trust model to evaluate the trustworthiness of sellers. Nowadays, people provide their feedback after a long time of usage only on social media platforms like Instagram. Therefore, these comments play a major role in helping people decide if the product will be beneficial for them over a long period of time. Mining such content to evaluate people’s sentiments can play a critical role in making decisions to keep the situation under control. {objective} Six different classifiers have been used to classify the data. The experiment achieved the highest accuracy of 76.7% with logistic regression. This study can be useful to determine the trustworthiness of the company.
Predicting Stability of Slope by Amplitude and Coherence Using a Naïve Bayes Classifier
Authors: Malekian Maral , Momayez Moe , Bellett Pat , Carrea Fernanda
Published: March 2023

Abstract: Slope instability is a challenge in both mining and civil engineering industries. Current ap-proaches to slope stability analysis are mostly based on slope deformation data provided by mon-itoring equipment. This study proposes a new method to estimate slope stability using amplitude and coherence obtained from slope stability radar data. More than 160,000 data points from 10 slope failures were collected with GroundProbe’s slope stability radar systems. They were used as input dataset in a Naive Bayes model for classification into two groups of stable and unstable slopes. The classifications were conducted based on different range limit values for amplitude and coherence. The findings were validated against slope deformation behavior in each case. The results show that 91 percent of the data that are classified as unstable slope by the Naive Bayes Gaussian method belong to slope failure events and are categorized correctly. The coherence and amplitude range values proposed in this research can be utilized by mining operations to determine the stability of slopes in conjunction with slope deformation and inverse velocity data.

In the modern world driven by technological advances, digital information networks, and globalization of many sectors of the economy, intercultural competence is needed to interact with people from different cultures, work in international teams, work abroad, live, study, and implement projects. In this study, we explored how to assess the intercultural competencies of foreign language teachers and researched the content and methodology that condition these competencies. We also describe how we assessed intercultural competencies among students before and after Russian language reading classes through the methods that we developed. Further, the article presents research findings related to the changes in intercultural competence and the content and methodology of the training handbooks.

АНУ-ын Портланд судалгааны байгууллага шилдэг зөөлөн хүчний бодлогыг хэрэгжүүлж буй орнуудыг эрэмбэлэн жил бүр “Soft power 30” судалгааг гаргадаг. Франц улс 2017 онд тэргүүн байранд, 2018 онд Их Британи улсын дараагаар хоёрт, 2019 онд мөн тэргүүн байранд тус тус шалгарсан байна. (Portland, 2022) Франц улс дэлхий дахинд гадаад бодлогоороо тэргүүлж, олон улсын харилцаанд онцгой үүрэг гүйцэтгэдэг гүрний нэгд тооцогддог. Нөгөөтэйгүүр франц хэл дэлхийн олон улсын байгуулагуудын албан ёсны хэл болж байна. Харин Франц улсын явуулж буй зөөлөн хүчний бодлого гэгдэх нөлөөллийн бодлого нь АНУ-ын Харвардын Их Сургуулийн эрдэмтэн Жозеф Най-н тодорхойлсон “Зөөлөн хүч” гэх ойлголтоос ялгаатай байгаа юм. Бид уг өгүүлэлдээ хэрхэн БНФУ-ын зөөлөн хүчний бодлогыг хэрэгжүүлж, хэл, соёлоо дэлхийд түгээж буйг жишээ баримт түшин авч үзэх болно.

We can say that there are two factors - external and internal - influencing the decision to send the Russian Armed Forces to Ukraine. The main factor in this case is, of course, external or foreign. The primary foreign factor in making decisions on special arrangements is NATO's advance to the East, to Russia's borders, which in the opinion of the Russian leadership, poses a real threat to the security of the Russian Federation. According to the UN Charter, a state has the right to self-protection, including by military means, if it sees threats to its independence and sovereignty. Secondly, Ukrainian nationalists de facto pursue a policy of "genocide" in the Donetsk People’s Republic and Lugansk’s People’s Republic (DPR and LPR). According to official data, from 2014 to 2022, more than 14,000 people were killed there due to the military actions by the Ukrainian army, encouraged by the US and the EU. Both DPR and LPR are populated by Russian-speaking people. The special operation, according to the Russian leadership, is aimed at protecting and restoring basic rights and freedom of the Russian-speaking people, violated by the Ukrainian authorities, which is fully consistent with international humanitarian law. In the western terminology, this is called "humanitarian intervention." Finally, the militarization and nazification in any state in any form of them are prohibited by international law. Therefore, de-militarization and de-nazification of states are fully legitimate which meet international norms and principles, including the UN Charter. As for as domestic legal factors of making a decision on a special operation, it should be emphasized that all the necessary internal legal basis were created, for instance, the request of the State Duma of the Russian Federation to Putin to recognize the DPR and LPR, the official recognition of the Russian Federation of these states, the law of the Russian Federation was approved by the Federation Council, which allowed the Russian armed forces to be sent abroad, the discussion in the Russian Security Council on this issue, etc. All this created an domestic legal basis for making a well-known decision on the special operation. Summarizing, we can conclude that the decision of the Russian Federation conducting special operation in Ukraine is in line with international standards and, as well as, with the domestic laws of Russia.

Since English and Mongolian are two different languages in their typology, it is important to specify the linguistic structure of the two languages by selecting a few prefixes with high frequency of use and to study the opportunities to translate them into Mongolian for indicating the specific features of use and method to express the meaning of abstractive communication and research materials and conclusions included in English teaching and translation have theoretical and practical importance. Because English is a fusional language, it has a prefix in its vocabulary and it included in auxiliary vocabulary. However, because off Mongolian is an agglutinative language, there is no prefix in its vocabulary. Therefore, English prefixes are often translated into Mongolian language, literally using grammatical tools. In this study, the grammatical meanings and functions of some English prefixes (at, in, on) indicating time compared with the Mongolian language tense and semantic units, and then, based on bilingual documents, it presents an overview of the features in meaning and function, and emphasis of translation opportunities.

Objetivo: Describir el perfil epidemiológico y clínico de los pacientes pediátricos que fueron atendidos por sospecha de infección de COVID-19, entre marzo y octubre del 2020, en el Hospital Universitario San Ignacio (HUSI), en Bogotá, Colombia. Materiales y métodos: Diseño de corte transversal. Descripción de los pacientes con edades comprendidas entre 1 mes de vida hasta 1 día antes de cumplir 18 años, valorados entre en marzo y octubre del 2020, que fueron abordados por cualquier servicio de atención pediátrica de un hospital universitario por sospecha de infección por COVID-19, según los protocolos nacionales e institucionales vigentes. Se registraron variables demográficas y el motivo de consulta de todos los individuos con sospecha de infección. Únicamente cuando se confirmó la infección por SARS-CoV-2 se registraron las variables relacionadas con aspectos clínicos de la enfermedad y su evolución. Resultados: Se evaluaron 920 registros médicos de pacientes pediátricos con sospecha de infección por SARS-CoV-2, de los cuales hubo 157 casos confirmados con infección por COVID-19. El principal motivo de consulta para sospechar infección fue fiebre en un 50% de los casos. En los pacientes con confirmación virológica el 32.48% de los casos atendidos requirieron manejo hospitalario. Se sospechó MIS-C en 5 pacientes que requirieron manejo en unidad de cuidados intensivos. En el lapso evaluado no hubo fallecimientos asociados a la infección por COVID-19. Conclusiones: La infección por SARS-CoV-2 se relaciona en la mayoría de los casos con un espectro de enfermedad leve en la población pediátrica. Este estudio sugiere que podrían ser mayores los pacientes pediátricos que debutan con síntomas gastrointestinales que respiratorios, y que la frecuencia de complicaciones renales debe ser tenida en cuenta en los pacientes en quienes se sospecha el síndrome inflamatorio sistémico asociado al COVID-19.

Background: Non-homogeneous results about the frequency of HPV in leukoplakia are presented in current literature, possibly linked to different factors. Among them, a diverse HPV geographical distribution was suggested. This study aimed to describe the frequency of HPV in patients diagnosed with leukoplakia. Patients & Methods: A cross-sectional study was carried out at the Facultad de Odontología, Universidad Nacional de Córdoba. HPV status was studied by polymerase-chain reaction (HPV-PCR) and p16 by immunohistochemistry. HPV status was analyzed concerning the clinical-demographic features using the Fisher test and the McNemar test. Results: There were included 33 patients diagnosed with different subtypes of oral leukoplakia. HPV genome was detected by PCR in 48.5% (n=16). The most common viral genotype was HPV16. p16 was positive in 27% (n=9) of the cases. The concordance between HPV detection techniques showed poor or weak agreement (Mc Nemar 0.1185). Except for chronic mechanical irritation with HPV-PCR + (p=0.0049), and tongue location with HPV-PCR + (p=0.0366), no significant statistical association between the other included variables was found. Conclusions: The low frequency of HPV in this study agrees with previous studies of our region. Chronic mechanical irritation could play a role in the development of HPV-associated leukoplakias, mainly located on the ventrolateral tongue.
