English is a foreign language studied in schools and is one of the compulsory subjects. However, a problem occurs in its implementation: the tendency to learn English using a focused memorization method. This can hinder English learning, focusing on the concept that language is part of culture, not just a series of memorized words. One learning method that can be used is by implementing humor. Humor serves as a bridge between teachers and students to create a more relaxed and comfortable classroom environment. This research aims to investigate the source of English Learning materials in the form of jokes from Stand-Up Comedians and ensure their use in English learning routines. The approach used in this research is descriptive qualitative, using the observation method. The research sample consists of 25 videos containing jokes obtained from English Stand-Up Comedians' TikTok user accounts. The data was then analyzed to identify the types of jokes used in each video and their use in English learning. The results show that the type of joke widely used in the content is Ridicule; however, the suitable joke techniques for use in English learning in the classroom are Politeness Strategy and Paralanguage. AbstrakBahasa Inggris merupakan bahasa asing yang dipelajari di sekolah dan menjadi salah satu mata pelajaran wajib.

Published: March 2024

Earthquakes cause damage and often cause casualties, where 30% of the victims are children and adolescents. Earthquake mitigation education should be conducted to improve earthquake literacy in children. The National Search and Rescue Agency organizes an education program to provide knowledge on natural disaster mitigation facilitated by instructors who give PowerPoint-assisted lectures. This delivery strategy is ineffective because earthquake mitigation content must visualize earthquake events and emergency responses. Experts determined the most effective video-based media for earthquake mitigation, so animated videos needed to be developed for this program. This study aims to develop an animated video of earthquake mitigation when it occurs in elementary schools. Products are developed with the ADDIE model. The instrument consists of a questionnaire containing criteria on the Likert scale. The analysis technique uses percentages. Animated videos developed are considered feasible as instructional media by experts.

Published: March 2024

Collision avoidance mechanisms are important topics for studies in the field of autonomous vehicles. We could obtain prior information about the collision from the movement angles of vehicles. Therefore, it is important issue to learn the movement angles of vehicles in motion. In the study, an architectural model is developed that learns the horizontal movement angles of vehicles to form a base for collision warning systems. YOLOv3 is modified and used on motion profiles. Thanks to the learned angle values, also the bounding boxes match the traces in the motion profiles smoothly. The results obtained have a mAP value of 79% and an operating speed of 36 FPS. These results are better than when trained on motion profiles of the YOLOv3 architecture. In addition, the use of the new architecture on motion profiles and factors such as noise and bad weather in the image do not adversely affect the results. With these features, a fundamental step has been taken for anti-collision systems.

Authors: Mitrokhin Sergey D. , Mironov Andrey Yu. , Aleshkin Andrey V. , Galitskiy Anton A. , Suranova Tatyana G. , Mironova Anna V.
Published: March 2024

BACKGROUND: During the coronavirus disease 2019 pandemic, the sale of antimicrobials (AMPs) in the pharmacy network and their purchases by healthcare facilities of the Russian Federation have significantly increased. Microbiological monitoring conducted at the City Clinical Hospital No. 67 named after L.A. Vorokhobov of the Moscow Health Department in 2020–2021 revealed an urgent problem: gram-negative bacteria, which are dominated by multidrug-resistant (MDR) strains, are now mainly isolated from patients with healthcare-associated infections (HAIs). Pharmacoeconomic studies have shown that the cost of one course of targeted antibiotic therapy for HAIs can increase by 6–12 times compared with a similar course of therapy in the absence of nosocomial MDR and extensively drug-resistant (XDR) pathogens.
AIM: To increase the effectiveness of preventive measures aimed at preventing the spread of hospital-acquired pathogen strains in the intensive care unit (ICU) using effective bacteriophages against MDR strains of Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus, and Acinetobacter baumannii, which were selected in accordance with an individualized algorithm.
MATERIALS AND METHODS: The study included two groups, totaling 20 patients, who were on prolonged mechanical ventilation in the ICU of City Clinical Hospital No. 67 named after L.A. Vorokhobov of the Moscow Health Department in 2022. The second group received 20 mL of bacteriophages via an intragastric tube for five consecutive days. The concept of a personalized approach to phage therapy for various forms of HAIs caused by nosocomial MDR pathogens in patients of a multidisciplinary hospital has been proposed and tested.
RESULTS: With this medical technology, the effectiveness of phage therapy for various nosological forms of HAIs caused by nosocomial MDR and XDR strains increased by 30%, and the effectiveness of the initial antibiotic therapy regimen was ≥70%. The economic effect of the combination of antibiotic therapy and phage therapy (booster therapy) amounted to more than 3 million rubles compared with the use of AMP alone for treating patients with HAIs caused by nosocomial MDR/XDR strains.
CONCLUSIONS: Booster therapy as a variant of IIB therapy reduces the cost of treatment of AMPs of various forms of HAIs by ≥2.5 times compared with AMPs alone.

BACKGROUND: The Gam-COVID-Vac vaccine was proven effective in preventing the severe course and adverse outcomes of COVID-19 during different periods of the pandemic. However, the effect of vaccination on laboratory marker levels in hospitalized patients during the spread of the omicron variant of SARS-CoV-2 has not been sufficiently studied.
AIM: To assess the effect of vaccination on the severity and outcomes of COVID-19 in hospitalized patients during the dominance of the SARS-CoV-2 omicron variant in Russia.
MATERIALS AND METHODS: This case–control study included adult patients diagnosed with COVID-19 (U07.1) and hospitalized in infectious hospitals in Moscow between February 1, 2022, and July 31, 2022 (n=119). The main group included individuals vaccinated with two doses of Sputnik V vaccine (n=59). The control group included individuals who were not vaccinated (n=60). The median patient age was 66 [interquartile range, 41–66] years, and 58.8% were female. The chi-square test for categorical variables and the Mann–Whitney test for continuous variables were used for the analysis. P-values 0.05 were considered statistically significant.
RESULTS: Viral pneumonia was less likely to develop in the vaccinated group than in the unvaccinated group (46.7% and 18.6%, respectively, p = 0.007). The proportion of patients without lung damage (0 CT-severity scores) in the vaccinated group (72.0%) was significantly higher than that in the unvaccinated group (42.9%) (p=0.003). In the vaccinated group, the levels of C-reactive protein on admission were lower (29.1 [7.4–68.6] mg/L and 75.1 [32.4–104.0] mg/L, p 0.001), and the highest level was recorded during hospitalization (38.2 [12.0–84.0] mg/L and 92.2 [45.3–137.4] mg/L, p 0.001). The D-dimer levels before discharge were lower in the group of patients vaccinated 6 months ago than in the unvaccinated group (157.0 [107.0–297.0] ng/mL and 316.0 [125.0–556.0] ng/mL, respectively, p = 0.014). The frequency of deaths in the control group (11.7%) was 6.9 times higher than that in the main group (1.7%) (p = 0.030).
CONCLUSIONS: Completion of the primary vaccination course of Sputnik V vaccine resulted in lower levels of prognostic markers of severe COVID-19 (C-reactive protein and D-dimer) and a decrease in the frequency of pulmonary and fatal outcomes than in the unvaccinated group during the dominance of the omicron variant of SARS-CoV-2.

Published: March 2024

Coinfections are becoming increasingly relevant and urgently require research. The development of international tourism has caused the rapid spread of infectious diseases from countries with unfavorable sanitary and hygienic conditions. This article analyzes the clinical case of a patient who recently returned from India and developed a combined course of typhoid fever and leptospirosis due to astrovirus infection and blastocystosis. The disease was characterized by symptoms of enteritis, low-grade fever, and mild intoxication. The patient repeatedly sought medical help. Diagnoses of “acute respiratory viral infection” and “intestinal infection of unknown etiology” were established. Symptomatic therapy was performed without a positive effect; fever and severe asthenic syndrome persisted. The patient was hospitalized on the 18th day of illness with moderate severity. Taking into account clinical, anamnestic, and epidemiological data and laboratory examination results, typhoid fever was diagnosed. A polymerase chain reaction (PCR) test identified astrovirus RNA in the stool, and Blastocystis hominis was detected during stool examination. Despite the ongoing pathogenetic and antibacterial therapy, considering the determination of the pathogen’s sensitivity to antibiotics, the patient’s condition worsened. On day 23 of the illness, jaundice, hemorrhagic syndrome, and signs of acute renal failure were noted. Through in-depth analysis of changes in the clinical and laboratory findings, considering epidemiological history data (stay in a region endemic for leptospirosis), leptospirosis was diagnosed and treated with antibacterial therapy. Complex intensive therapy using extracorporeal treatment methods helped prevent the development of unfavorable outcomes of combined pathology. This clinical case emphasizes that doctors must be wary of imported infections and conduct additional comprehensive investigations of suspected cases.

Published: March 2024

The increasing development of today's technology specifically in the field of telecommunications triggers new problems associated with the increasing number of network connectivity users so that this makes the increased load of traffic on the Base Station (BS). To address traffic problems, a D2D technology is needed as a solution to enhance connectivity on 5G networks. In the use of D2D is still not optimal for dealing with the rapidly increasing load of traffic due to the large number of users. This research suggests the addition of devices in D2D communication, namely Relay Node. (RN). The results of the study showed that by using the relay aided communication scheme can improve the sumrate performance parameter is 1,970 × 107 bps and the spectral efficiency is 19,704 bpz/Hz, but less effective in the power efficiency parameter is 7,672 × 103 bps/mW due to the addition of relay devices that increase power consumption. Using iterative algorithms on relay aided communication schemes has been shown to improve performance parameters values more optimally than using full duplex and half duplex communications schemes. Therefore, the relay aided scheme is the most accurate communication scheme in dealing with transmission systems on D2D because by using the aided relay scheme, sumrate and spectral efficiency are improved by 55%.

The reporting of course attendance is an essential component of academic administration. This research designs and deploys a smart attendance system by leveraging proximity-based IoT. The smart attendance system is built upon the Android operating system to detect the beacon of the proximity sensor and is integrated into a database installed on a cloud server. The application supports three different features designated for administrators, lecturers, and students, respectively. The developed application accelerates data input for the campus administrator, records the course log efficiently, and concurrently reports the more secure student attendance from manipulation since it applies a single user identity. This study conducts a field test to evaluate the operational efficacy of the system by sampling students who enrolled in the course. The test involves utilizing a range of mobile devices to access the application connected to two courses. In one course, the functionality testing result is 91.67%, while in another, it is 100% successful. The limitation arises as a result of the incapability of the mobile device to perceive the beacon.

In the last three decades, many researchers have published their findings on the storage of thermal energy using various phase transition materials (both organic and non-organic). One of their goals was to have a higher heat storage capacity with a shorter heat charging cycle for thermal energy storage. This study looked into a floating capsule thermal energy storage system (TESS). A number of spherical capsules filled with beeswax were placed in a paraffin-filled cylindrical shell. With heat transfer fluid flowing through three hexagonal tubes arranged at 120° inside the TESS core, the two phase change materials (beeswax with a thermal conductivity of 0.25 W/mK and paraffin with a thermal conductivity of 0.23 W/mK) were charged and discharged. For the proposed TESS, a mathematical model was created and utilised to forecast thermal energy storage capacity and charging/discharge times for various configurations. In TESS, a 70–30% mixture of the two PCMs results in a 21.5 percent increase in heat storage capacity when beeswax alone is used, and an 8.4 percent decrease in storage capacity when paraffin alone is used. For a heat storage capacity of 7300 kJ, the model estimates charging and discharging times of around 2.6 and 3.2 hours, respectively.

The current study attempts to predict the outlet temperature of a hybrid nanofluid heat pipe using three machine learning models, namely Extra Tree Regression (ETR), CatBoost Re-gression (CBR), and Light Gradient Boosting Machine Regression (LGBMR), in the Python environment. Based on 7000 experimental data (various heat input, inclination angle, flow rate, and fluid ratio), different training (95%–5%) and testing (5%–95%) split sizes, a closer prediction was attained at 85:15. The three attempted machine learning models are capable of predicting the outlet temperature, as evidenced by the less than 5% deviation from the experi-mental results. Of the three attempted machine learning models, the ETR model outperforms the other two with a higher accuracy (98%). Further, the sensitivity analysis indicates the ab-sence of data overfitting in the attempted models.

Published: March 2024

In this research, flat plate solar collectors (FPSC) were studied due to their simplicity, low maintenance, and cost-effectiveness. The study focused on comparing FPSC thermal performance using CuO/H2O nanofluids. Experiments were conducted over three months during the Iraqi weather conditions (January, February, and March) with carefully selected nanoparticle concentrations. Data was collected from 9 A.M. to 3 P.M., using various mass flow rates (ranging from 0.003 to 0.076 kg/s). Results showed a direct correlation between temperature and nanoparticle concentrations, with the highest outlet temperature (50°C) observed at 3 P.M. for 1% CuO-water nanofluid. Notably, at 1 P.M. in March, the 1% CuO-water nanofluid exhibited a 32% increase in collector thermal efficiency, surpassing pure water by 11.3%. This would improve the performance of FPSC by achieving higher efficiency increments. These improvements were attributed to the unique physical properties of nanoparticles, their increased surface area, and higher thermal conductivity. The study determined that the optimum nanofluid concentration for superior collector efficiency was 1%.

Published: March 2024

In this study, a comparative performance evaluation of an experimental ejector refrigeration system was conducted for various operating modes. The experimental setup was operated in different modes: conventional vapour compression refrigeration (CVCR), conventional dual-evaporator system (CDES), and dual-evaporator ejector system (DEES). The system was tested under different operating conditions, including varying condenser temperatures and mass flow rates. The results of the evaluation showed that the highest total cooling capacity and coefficient of performance (COP) were achieved in the DEES mode, while the lowest total cooling capacity was observed in the CDES mode. The lowest compressor power was calculated when the system was operated in DEES mode. When the condenser temperature was 33°C, the compressor power obtained in the DEES was 22.7%, 5.4%, and 17.7% lower than that of
the CVCRA, CVCRB, and CDES modes, respectively. In conclusion, the performance of the ejector-operated system was found to be superior to the other configurations, and the ejector contributed positively to the system performance.

Published: March 2024

Rotary kilns have been widely employed in various industrial uses, especially the cement production. This article deals with enhancing the thermal performance of a rotary kiln duct with V-shaped grooves mounted on the outer wall. Four V-shaped grooves with different depths h/D ranging from 0.1 to 0.4 were designed. The Reynolds Averaged Navier–Stokes equations (RANS) of two-dimensional steady-state flow are used to model the governing flow equations by using the finite volume approach (FVM) in FLUENT. k-ε standard, k-ε Realizable, k-ω SST and k-ε RNG turbulence models of the RANS approach and the k -ω SST model has been adopted to validate CFD results. In this study, the numerical results have revealed that the increase in groove depth decrease the temperature of the rotary kiln’s outer wall than the smooth walls and gives the largest Nu number, especially for the groove with h/D =0.3 and 0.4 depths.

Energy is a fundamental necessity for man›s life in the digital world today. The rapid depletion of fossil fuel resources forces rigorous alternative fuel analysis. Petroleum diesel can better replace vegetable oils, edible or motored today. The rapid depletion of fossil fuel resources forces rigorous alternative fuel analysis. Petroleum diesel can better replace vegetable oils, edible or not. Karanja may be a possible supplier of diesel fuel for non-edible oil substitution. Current combustion surfaces for pistons, valves, and cylinders have been filled with ceramic materials, which make the engine totally adiabatic (LHR). The performance of a biodiesel-powered compressing ignition (CI) engine may be further boosted by utilising the engine›s heat effectively and increasing thermal efficiency. Exhaust Gas Recirculation (EGR) is actually one of the most important methods of limiting NOx emissions in internal combustion engines. Explore the output with and without exhaust gas recirculation on a retarded timing engine with diesel and karanja oil methyl ester (KOME). The LHR with a retarded timing engine yielded improved thermal brake efficiency (TBE), decreased HC, smoke, and CO emissions, while increasing KOME›s NOx in comparison with an uncoated engine. As the EGR rate grew, NOx and BTE were reduced marginally with increased HC, CO, and smoke. 24.1 g/kw-hour CO, 10.1 g/kw-hour NOx, and 0.55 g/kW-hour HC were registered at 20 percent of EGR.

This study aims to discuss whether local government policies affected the coffee farmers’ welfare during the COVID-19 pandemic. Gayo coffee is a superior commodity that supports the economy of almost 90% of Central Aceh people, so coffee-related policies greatly determine their welfare. The COVID-19 pandemic, on the other hand, has influenced the coffee business globally, which has caused difficulties for farmers selling coffee at a reasonable price, and this condition has affected the Gayo coffee farmers, who have been export-oriented. This study used a qualitative method with a case study approach. The informants in this study consisted of 8 people. Data was collected through interviews and documentation, and then the data was analyzed using data reduction, data display, and conclusion drawing. The results showed that the government of Central Aceh fostered coffee cultivation for farmers, helped open export markets to prevent and protect Gayo coffee farmers from the impact of COVID-19, and assisted business capital. Hence, government policies of Central Aceh have not been able to achieve Gayo coffee farmers’ welfare as seen from the shallow targets and goals made.
