Published: June 2023

Molds are toxic and harmful to the human body. In this study, we intended to produce anti-mold wallpaper using easily obtained substances. First, four strains were separated and identified from actual moldy wallpaper. Next, Vanillin and o-Vanillin were both selected as anti-mold substances due to the fact that they were confirmed to have growth-inhibitory effects on the four identified strains. For all the strains, the growth inhibitory effect of o-Vanillin was higher than Vanillin. It was verified that the higher the treatment concentration of Vanillin and o-Vanillin, the higher the ROS production in all fungi, which means the anti-mold activity of Vanillin and o-Vanillin is related to the increase in ROS production. Vanillin and o-Vanillin were smeared on the wallpaper to confirm this anti-mold effect. Mold growth was suppressed in the wallpaper treated with Vanillin of 0.05M or more and o-Vanillin of 0.01M or more, but at concentrations below that, the growth of the mold did not differ significantly from the control group. The cytotoxicity of Vanillin and o-Vanillin was directly proportional to the concentration of the treated candidate substances, and the cytotoxicity of o-Vanillin was higher than that of Vanillin. Therefore, it would be appropriate to apply Vanillin of 0.05M or less for the use of anti-mold wallpaper. Based on its stronger anti-mold activity when compared to anti-mold drugs on the market, Vanillin can be used in a wide variety of places, including anti-mold sprays and paints.

Published: June 2023

This research introduces a new method to calculate the area of inellipse of triangle. This formula is derived using the coordinates in the complex plane, the geometrical property of the ellipse, and the Siebeck-Marden theorem rather than the projective transformation and Affine transformation used in the conventional formula derivation. Through this paper, the following results can be obtained. Firstly, we calculated the area of inellipse of triangle related to the ratio of a divided triangle edge determined by the tangency point. Secondly, we derived the area and the ratio of a divided triangle edge of various well-known inellipses of triangle. Thirdly, we reconfirmed that the Steiner inellipse has the maximum area among all inellipses of triangle. This research established the relationship between the area of inellipse of triangle and the Siebeck-Marden theorem, which gives the two foci of inellipse. The new approach could contribute to further research of inellipses.

Published: June 2023

The purpose of this study is to predict the desk illumination of the classroom using the results obtained through sensors that can measure the natural lighting environment, and to save energy by dimming the artificial lighting of the classroom. In addition, a theoretical equation for predicting desk illumination through sensor values was produced. However, the desk illumination measured through the theoretical formula had a disadvantage of 70% accuracy and could not consider the blinds in the classroom. Machine learning was conducted to solve these shortcomings. Since constructing a machine learning dataset through actual measurement has time and space limitations, a simulation was produced to construct a dataset. As a result of comparing the produced simulation and the measured value, there was an error within 5%, which was used as machine learning data. There are a total of 192 sets and 1,728 data of natural light sensor values and classroom desk illumination values measured by changing direction, blind use, season, and time through simulation. As a result of learning this through the XGBoost regression model, the simulation value showed an accuracy of 95.4%, and the actual measurement value showed an accuracy of 95.2%. In addition, as a result of predicting desk illumination by natural lighting in each season and calculating the lighting energy saving effect, it was found to have an energy saving effect of 13.0% in winter, 29.6% in spring and fall, and 40.7% in summer.
Biomechanical Analysis of Labial Movement in the Hunting of Dragonfly Nymphs
Authors:   Korean Science Education Society for the Gifted, Kim Minseo , Kim Sujin , Kim Myoung Hee
Published: June 2023

Dragonfly nymphs are known for their ability to rapidly snatch prey by extending their folded labium, despite the resistance of water. The labia of dragonfly nymphs can be categorized into two types based on their shapes: Scooped and Flat. Orthetrum albistylum and Anax parthenope were selected respectively as the most representative species of the scooped and flat labial types. This study aimed to examine the hunting behavior of dragonfly nymphs through analyzing the biomechanical characteristics of the scooped and flat labia and three separate analyses were performed. First, we conducted a quantitative analysis of the labium structures by measuring the length, mass, and joint angle of each part through anatomical dissection. The result showed that the scooped labium has limitations in opening its joints compared to the flat one due to structural difference. Second, we analyzed hunting videos of dragonfly nymph using the Tracker program to measure physical quantities such as velocity and acceleration. The average Striking velocity of the labium is 0.40m/s in O. albistylum and 1.53m/s for A. parthenope. Third, we conducted two additional biomechanical analyses: (1) we calculated the magnitude of the force involved in the strike and (2) we compared the water resistance that the labia encountered during hunting using a second-order differential equation that calculates terminal velocity of damped oscillation. Our findings may suggest that the differences in the biomechanical characteristics of the labia can explain the ecological differences between O. albistylum and A. parthenope. We found out that O. albistylum is better adapted to catching small prey, whereas A. parthenope is more adept at catching larger and faster prey. This study is not only expected to contribute to better understanding of insects, but is also expected to be highly valuable for future research on biomimetic devices.

SARS-CoV-2 is a new pandemic infection that affects at the beginning the upper respiratory system, and, successively, all the organisms, due to cytokine storm, with serious consequences that can reach death. The aim of this work was the observation of the nasal mucosa of enrolled 60 patients, resulting negative for two weeks to the molecular swab for SARS-CoV-2, versus the control group. Rhino-fibroscopy and nasal cytology of nasal mucosa were performed for both the investigated groups. The observation of the samples showed the occurrence of plasmablastic lymphocytes and Downey II lymphocytes type. The former type of lymphocytes was prevalent against the second one, probably because of an immunological “scar”. The rhino-fibroscopy showed a “pseudo ischemia of nasal submucosa” at pre and pericranial levels, not occurred in the control group. The occurrence of atypical lymphocytes in the nasal smear was analog to that observed in the blood peripheral smear, probably caused by mechanisms of local immune reaction and dysregulation like those observed in other virus infections. Our findings suggest that the nasal mucosa study through the nasal cytology, can represent an important predictive tool of the SARS-CoV-2 infection.

Authors: Tanzeem, Mudassar  , Al-Thubaiti, Musaed M.
Published: June 2023

Ammonia is one of the basic ingredients for the fertilizer and mining explosive industries. Conventional ammonia production technologies have a high environmental impact owing to its high carbon dioxide (CO2) emissions. This study evaluates the prospects of blue ammonia through integration of different available technologies within conventional ammonia plants: the Kellogg Braun & Root (KBR) Purifier process, Topsoe and the Linde Ammonia process. Carbon Capture and Sequestration (CCS) and Gas Switching Reforming (GSR) technology are attractive pathways toward blue ammonia due to cost effectiveness and ease of implementation. Blue ammonia technology development has its own challenges to overcome while it has massive advantages and opportunities like blue ammonia utilization as an alternative fuel, availability of pre-existing infrastructure available for storage, enhanced oil production through CO2 pressurization. Given the increasing demand and international ammonia trade, advanced blue ammonia production from different available technologies like CCS & GSR offers an alluring way for natural gas exporting regions to contribute to global decarbonization.
A comparative analysis of recurrent neural network and support vector machine for binary classification of spam short message service
Authors: David Odera  , Gloria Odiaga
Published: June 2023

Over the years, communication through Short Message Service (SMS) has been a primary tool for mobile subscribers. SMS has varied applications in health, industry, finances, education and social networking among others. The growth of mobile devices and SMS usage has consequently increased the attack surface for cyber-criminals culminating to the proliferation of malicious activities introduced using SMS spam, phishing, spyware, malware etc. Ham messages are normal messages people trade with one another and are usually not unwanted by the recipient, while spam messages are unsolicited junk and redundant messages that may be sent to a large number of people at once and are usually unwanted. Various spam detection models have been developed using various traditional machine and deep learning techniques. However, most studies where comparison between deep and traditional machine learning algorithms is done, have unfortunately omitted K-Nearest Neighbors and Support Vector Machine (SVM) which are empirically deemed as the most popular traditional machine learning algorithms. In this study, therefore, we develop a deep learning model based on Recurrent Neural Network (RNN) for Spam and Ham SMS classification and compare its performance against SVM model for the same University of California (UCl) SMS dataset. The results show that RNN has a slightly higher training and validation accuracy of 0.98 compared to SVM at 0.94, however, the false positive rate of SVM is marginally lower. Exploring application of deep learning with better optimization algorithms such as RNN improves accuracy, reduces computational complexities i.e. memory consumption and speed, and thus minimizing false positive rates. For future work, we suggest the use of varied performance metrics to validate the model in a distributed dataset environment.

Published: June 2023

Planned road expansion in Manokwari, West Papua, along 6.5 km of the Maruni - - Dr. Esau Sesa in phase I of 2024 will prioritize low-carbon development and climate resilience. Road design enhancement and economic and financial analysis are conducted in this research. In the economic analysis, the National Road Administration Agency, the Head of Public Works and Spatial Planning, and the Regional Development Planning Agency from the regency and provincial collaborated on budget tagging. The proposed design incorporates bicycle lanes, green infrastructure in tree-based pedestrian areas as an energy source for biomass pellets, solar panel-based street lights, drainage along pedestrians to anticipate extreme weather and flooding, rehabilitation of mangroves whose ecosystem function has diminished, and retaining buildings erosion for damaged mangroves. The economic analysis begins with the calculation of the Vehicle Operating Cost (VOC) for large cities using the ratios 1:7 (Light Vehicle, LV) and 1:4 (Heavy Vehicle, HV). Time savings of up to 10 minutes and total VOC contribute to the total savings. Furthermore, an analysis of NPV > 0, IRR > 15%, BEP in the fifth and sixth year, and net B/C ratio > 0 indicates that road improvement is feasible based on economic analysis.

Metabolic syndrome is the most common issue faced by a large population, especially women and old aged people. This is not only a clinical issue for the women and adults but also a social concern particularly among children and adolescents in high-income areas. The prevention and Cure are the hottest area of discussion through the years and many recommendations came regarding preventions and treatments as depressing the asprosin hormone level which is a major cause of high appetite and increase sugar level in blood can help in controlling the obesity and few metabolisms, and nutraceuticals discoveries. There are few proposals about adding psychological interventions in treatments, as these people should also be motivated psychologically as these people sometimes these people face social isolation and give up on treatments. In the SARS-COV 2 pandemic the incidences of this syndrome due to restricted movement of people and other factors.

Ecotoxicological studies have been carried out on the precarious effects of heavy metal pollution and exposure attributed to anthropogenic practices such as mining, industrial and agricultural activities, which poses serious health challenges. This study investigated ten (10) heavy metals namely As, Cd, Co, Cr, Cu, Fe, Hg, Ni, Pb and Zn in one hundred and fifteen samples from water sources and staple food cultivars around Igade mining site in Mashegu Local Government Area of Niger State, North-Central Nigeria, using Atomic Absorption Spectrophotometer (AAS). The result revealed the concentrations of heavy metals in staple food cultivars consumed at Igade to be within the recommended maximum levels as stipulated by WHO/FAO, but As2+ and Cd2+ were higher in legumes (1.510 ± 0.169 mg/kg) and vegetables (1.666 ± 0.154 mg/kg); and cereals (0.328 ± 0.012 mg/kg) and tubers (0.421 ± 0.176 mg/kg) respectively. This implies that the artisanal mining contributed to the exogenous bioaccumulation of these metals in staple food cultivars following the pattern: Fe > Zn > Cu > As > Pb > Cr > Cd > Hg which could accumulate and destroy vital organs thereby affecting human health upon consumption. Also, the mean concentration of the heavy metals in various water sources at Igade mining site decreased in the order Zn > Fe > Cr > Cu > As > Hg > Pb > Cd > Ni. Levels of As, Hg, Pb, Fe, and partly Cr in water sources were observed to be higher than the WHO and NSDWQ recommended standards for drinking water. Thus, their continuous consumption poses potential health risk to inhabitants, and therefore, there is need for the provision of safe alternative water sources; proper sensitization and monitoring of the mining activities to curb health risks and the extent of heavy metal contamination.

Published: June 2023

Sarcopenia is a progressive generalized skeletal muscle disease characterized by loss of muscle mass and decreased muscle function with an increased risk of adverse events. For a long time, loss of muscle mass and function has been studied as a clinical symptom in severe diseases and conditions in oncology, endocrinology, rheumatology, and a number of other systemic diseases. However, with the increase in life expectancy and aging of the population, sarcopenia, as an independent age-associated disease, comes into general medical practice and makes a significant contribution to the rates of disability and mortality. To date, several definitions of sarcopenia, screening methods and diagnostic criteria for this disease have been proposed by various international research groups. This review presents evolution of definitions and diagnostic criteria for sarcopenia and severe sarcopenia. Changes in the algorithm for sarcopenia diagnostics according to the latest recommendations of the European Working Group on Sarcopenia for Older People (EWGSOP) second revision, published in 2018 (EWGSOP2), as well as the results of the consensus of the American Geriatric Society and the International Group on study of sarcopenia. This review summarizes practical issues regarding methods for assessing muscle mass, muscle strength and skeletal muscle function, diagnostics threshold for sarcopenia from leading international research groups, as well as the results of researchers’ work on adapting tests for assessing sarcopenia in Russia.
Optimization of surgical access in hip arthroplasty
Authors: Nasirli J. A.
Published: June 2023

Relevance. Total hip joint arthroplasty with a wide range of both classical and modifi ed approaches is a successful method of treating joint diseases in the fi nal stages. It should be noted that in recent years, there has been an increased interest among scientists — specialists in this fi eld — in developing and implementing new, more optimal approaches for primary and revision arthroplasty.

Research objective: to determine the advantages and disadvantages of surgical approaches in arthroplasty of the hip joint in patients with dysplastic coxarthrosis.

Material and methods. For this study, we observed 80 patients (18 men, 16 women) aged 45 to 60 years with dysplastic coxarthrosis of the hip joint who were undergoing treatment in the trauma and orthopedics department of the therapeutic surgical clinic of the Azerbaijan Medical University. The comparison group included 25 patients who underwent total hip joint arthroplasty from a posterior-lateral approach; 25 control group patients underwent surgery with a Harding approach, and 30 main group patients underwent surgery from the proposed modifi ed approach. All approaches were performed as indicated. Before and 6 and 12 months after arthroplasty, the WOMAC index, C-reactive protein level, and ESR in the blood were studied in patients.

Results. In the control group, some positive dynamics of clinical and biochemical indicators were noted at 6 and 12 months, but their values did not diff er signifi cantly from those of the comparison group (p > 0.05), but were signifi cantly higher than those of the main group (p < 0.001). Analysis of arthroplasty outcomes revealed a higher percentage of positive clinical outcomes with a signifi cant reduction in WOMAC index values and a decrease in C-reactive protein and ESR levels when using minimally invasive surgical techniques. Thus, the anterior approach with low intraoperative trauma is more optimal for patients with dysplastic coxarthrosis, as it promotes faster functional recovery and causes fewer infl ammatory complications. The posterior-lateral approach, like the anterior one, is optimal, since the above indicators did not diff er signifi cantly from those of the anterior approach. With the lateral approach, due to a higher risk of wound infection, the recovery time and reduction of the infl ammatory reaction are longer.
