Published: October 2024

The use of an IoT-based monitoring system for CO and CO2 gases in elderly homes is a necessary innovation for remotely monitoring air quality. This work was successful in establishing a remote monitoring system that can measure CO and CO2 gases utilizing IoT technology combined with Blynk software. The MQ-7 sensors detect CO gas, while the MQ-135 sensors detect CO2. Data from these sensors is delivered to a central server, which then sends it to the I2C 16X2 LCD panel and Blynk software, allowing data visualization via an internet connection. The study's findings indicate that this system can detect and monitor CO and CO2 gas levels with a high degree of precision. This device can also monitor air quality in real time using the Blynk software. As a result, users may accurately monitor air quality (CO and CO2 gases) in elderly homes.

Published: October 2024

The Indonesia National Single Window (LNSW) Agency developed a single submission system, namely the Indonesia National Single Window (SINSW) System, as a one-stop submission facility. Before the development of SINSW, the process of applying for business permits in Indonesia was complicated and time-consuming. This is because stakeholders have to process permits directly with various relevant ministries or institutions, causing data repetition and cost and time inefficiencies in the export, import and logistics processes. This research aims to analyze the transformation of LNSW into a one-stop business licensing and management agency through the implementation of SINSW and its impact on the efficiency of public services in exports, imports and logistics in Indonesia. This research also compares the implementation of the National Single Window (NSW) in Korea, Singapore, and Japan. The results of the research are recommendations for improving the efficiency of LNSW services in the future through the adoption of artificial intelligence (AI) via chatbots to handle complaints of slow responses for service users.

Published: October 2024

Multiple myeloma (MM) is a hematological malignancy commonly associated with bone pain, hypercalcemia, and renal failure. However, its presentation can occasionally mimic other medical conditions, which may delay diagnosis. This case report describes a patient who was initially diagnosed and treated for heart failure but was later found to have MM, highlighting the importance of considering MM in the differential diagnosis of heart failure.
A 56-year-old lady presented with recurrent episodes of shortness of breath, orthopnea, paroxysmal nocturnal dypsnea and bilateral lower limb swelling which she had been treated for decompensated heart failure with optimal therapy. She denied any family history of cardiovascular disease personal history of underlying medical condition and was a nonsmoker. This patient was diagnosed with multiple myeloma and probability of concomitant cardiac amyloidosis and commenced on bortezomib, thalidomide and dexamethasone (VTD) regime and standard optimal therapy of heart failure but her condition deteriorated. After a few days of starting chemotherapy, patient demised despite all the resuscitative effort. Multiple myeloma is common hematological malignancy with its distinct clinical features of “CRAB”, however, more attention and alertness should also be exercised by clinicians as to be able to diagnose it early.

Authors: Sayeed Ibrahim Hana Syafiqah , Huda-Faujan Nur
Published: October 2024

The application of plant-based waste materials as functional food ingredients in meat products has gained popularity owing to their nutritional richness and contributions to the circular economy and environmental protection.  As such, mushroom stems are one of the potential ingredients to be used in muscle products as a meat alternative, as they mimic the texture of meat. Therefore, this study aims to determine the physicochemical properties and nutritional composition of chicken patties with grey oyster mushroom stems.  In this study, five formulations of chicken patties were prepared with different ratios of chicken meat to the grey oyster mushroom stem: control (65%:0%), A (55%:10%), B (45%:20%), C (35%:30%), and D (25%:40%).  The chicken patties were analysed for cooking characteristics, physicochemical properties, and nutritional composition.  Results found that the grey oyster mushroom stem-based patties recorded higher (P<0.05) cooking yield and moisture retention as compared to the control.  The addition of grey oyster mushroom stems increased (P<0.05) the lightness (L*) due to the white colour of the grey oyster mushroom stems.  No significant difference (P>0.05) was observed in all formulations of patties' hardness, chewiness, springiness, and cohesiveness attributes, but the increment of grey oyster mushroom stems in chicken patties decreased the value of all these attributes.  Nutritional composition of chicken patty of formulation D (40% grey oyster mushroom stems) recorded significantly the highest (P<0.05) moisture and crude fibre compared to other formulations.  In addition, the energy content of chicken patties significantly decreased (P<0.05) proportionally with increasing levels of grey oyster mushroom stems.  This study indicated that grey oyster mushroom waste is a promising meat alternative ingredient that has great potential to be used in attaining meat products with enhanced nutritional and sustainability profiles in the current sector.
A Review on the Extraction of Silica Nanoparticles from Poaceae Family via Sol-Gel
Authors: Shya Athiera Ilma Mohamad Sopi  , Mohd Hafiz Abu Hassan
Published: October 2024

One of the valuable inorganic multifunctional chemical substances is silica, which can be found in crystalline, gel, and amorphous forms. On the crust of the earth, silica is the most complex and abundant family of materials, and it has been used extensively in ceramics, adhesives, detergents, dental materials, electronics, pharmaceutical items, and chromatography column packing. Several kinds of research have fascinated the recycling of agricultural wastes using extraction for useful products such as silica, lignin, adsorbents, cellulose, biofuels, silicon, carbon, and inhibitors. In this review article, we report most of the silica nanoparticles extracted from the Poaceae family since they accumulate significant amounts of silica, and most of them are easily found in Malaysia. This study investigates the significant amount of extracting silica nanoparticles from the Poaceae family via green technology sol-gel technique as pure silica can be produced with the potential to manage the size of the particle, size of distribution, and morphology via the reaction parameters in systematic monitoring. This technique can also produce pure silica using a low-energy method. Subsequently, the key chemical compounds that existed in silica nanoparticles are characterized and identified using FTIR analysis. According to this article, most of the Poaceae family species are considered to gain a high purity of above 90% of silica based on the quantification results. The Poaceae family is recognized for having high silicon concentrations. However, the concentration varies depending on the species.
Cosmology with shear ratios: a joint study of weak lensing and spectroscopic redshift datasets
Authors: Emas Ni Putu Audita Placida , Blake Chris , Ruggeri Rossana , Porredon Anna
Published: October 2024

The ratio of the average tangential shear signal of different weak lensing source populations around the same lens galaxies, also known as a shear ratio, provides an important test of lensing systematics and a potential source of cosmological information. In this paper we measure shear ratios of three current weak lensing surveys –KiDS, DES, and HSC– using overlapping data from the Baryon Oscillation Spectroscopic Survey. We apply a Bayesian method to reduce bias in shear ratio measurement, and assess the degree to which shear ratio information improves the determination of important astrophysical parameters describing the source redshift distributions and intrinsic galaxy alignments, as well as cosmological parameters, in comparison with cosmic shear and full 3x2-pt correlations (cosmic shear, galaxy-galaxy lensing, and galaxy clustering). We consider both Fisher matrix forecasts, as well as full likelihood analyses of the data. We find that the addition of shear ratio information to cosmic shear allows the mean redshifts of the source samples and intrinsic alignment parameters to be determined significantly more accurately. Although the additional constraining power enabled by the shear ratio is less than that obtained by introducing an accurate prior in the mean source redshift using photometric redshift calibration, the shear ratio allows for a useful cross-check. The inclusion of shear ratio data consistently benefits the determination of cosmological parameters such as S_8, for which we obtain improvements up to 34%. However these improvements are less significant when shear ratio is combined with the full 3x2-pt correlations. We conclude that shear ratio tests will remain a useful source of cosmological information and cross-checks for lensing systematics, whose application will be further enhanced by upcoming datasets such as the Dark Energy Spectroscopic Instrument.

Purpose. To carry out a kinematic analysis of a flat twelve-link hinged mechanism with three leading links, the basis of which is a structural group of links of the third class of the fourth order with rotational kinematic pairs, which is used in technological equipment. Methodology. The kinematic study of a flat complex mechanism of the third class with three leading links was performed using the mathematical modeling method in the Mathcad software environment. Findings. Using the method of mathematical modeling, the mechanism was presented in the form of free vectors built on its links, for which, taking into account the presence of three leading links, three vector contours were selected, which made it possible to draw up a system of vector equations of their closedness with further solving by a numerical method in the Mathcad software environment. The functions of the rotation angles of the mechanism links, their angular velocities and accelerations were obtained in analytical and graphical form depending on the rotation angle of the first driving crank of the mechanism, the calculation of the angular velocities and accelerations of all the driven links of the mechanism was performed. Originality. A sequence was developed and a kinematic study of a complex planar mechanism of the third class with three leading links was done, the basis of which is a structural group of links of the third class of the fourth order. Schematic modeling of the mechanism with three leading links was performed, a visualization schedule of its kinematic scheme was built, and a valid version of its assembly was obtained from many possible ones, for which the values of kinematic parameters of all its links were determined. Practical value. An analysis of the effect of the kinematic parameters of the three leading links of the third-class mechanism on the movement of the working body of the technological equipment was carried out. From the analysis of the obtained research results for the cycle of the mechanism the reason was found for the incomplete technological stoppage of the link, which should provide the working body of the machine for the required period of time. Recommendations of the elimination were made to identify the deficiency and proposals for the need to improve the drive of this equipment.

Published: October 2024

Purpose. Reducing the dispersion of radar reflections from local objects, with multi-frequency sensing, to solve the problem of orientation by radar reflections from objects. Methodology. Reflections from local objects in the entire frequency range of the radar station (RS) at the same radio engineering position were measured by three independent radars of the same type on different days and at different antenna elevations. The deviation of the radar stations in the position did not exceed 500 meters. Coordinates (azimuth, range) of reflections of several separate local objects were allocated for each radar. The average values of reflections from local objects and their dispersion in the frequency range were calculated. Using various algorithms, individual frequencies were sampled and the reflected signals were averaged at these frequencies. The decrease in the dispersion of the reflected signal from the number of frequencies at which reflections were measured and from the algorithm for selecting these frequencies was investigated. Findings. Averaging the values of reflections from local objects for several frequencies leads to a decrease in dispersion and, as a result, to a more accurate correspondence of the reflected signal level to the geometric size of the local object. The variance decreases most rapidly for a small number of frequencies selected for averaging when selecting frequencies located in an interval of at least 1% relative to each other. Originality. To solve the problem of orientation based on radar reflections from local objects, it is necessary to identify the landmarks selected on a digital terrain model. Due to the fact that local objects (hills) are a collection of many reflectors falling into the allowed volume of the radar, with different levels of reflections and random phases, there may not be radar reflection from a local object at a certain frequency, or it may be very small. In order to unambiguously identify all landmarks, measurements must be carried out at several frequencies. The work has established how many frequencies measurements should be performed at and on what principle these frequencies should be selected. Practical value. The advent of digital terrain models made it possible to solve the problem of terrain orientation by comparing radar reflections from local objects with reflection models based on digital terrain maps. Radar reflection models use mathematical expectations of reflection values, unlike real reflections, which have random deviations in signal levels depending on the operating frequency. Reducing the variance of these deviations increases the accuracy of identifying characteristic local objects (landmarks) used to orient the radar in the absence of data from satellite navigation systems.

Published: October 2024

One of the critical factors influencing the accuracy of a local geoid model is the quality of the digital elevation model (DEM). A properly selected high-resolution DEM can significantly mitigate errors in geoid modeling, gravity anomaly processing, and topography and downward continuation correction. Purpose. Evaluating the accuracy of five global DEMs obtained from open sources to identify the most suitable model for creating a local geoid. Methodology. The vertical accuracy of the DEMs was assessed by comparing the heights between the DEM and control points across different types of terrain. The reference values are based on 344 ground benchmarks, where GNSS observations were performed with subsequent adjustment of coordinates and heights. The accuracy analysis involved calculating statistical indicators of the height differences between the GNSS data and the DEM data. Findings. The standard deviation assessment showed favorable values for the COPERNICUS and ALOS DEMs, followed by SRTM, ASTER, and ETOPO. In the mean absolute error calculations for mountainous areas, the ALOS model performed best, followed by COPERNICUS, SRTM, ASTER, and ETOPO. For other types of terrain, COPERNICUS demonstrated the best results in mean absolute error. Originality. This study distinguishes itself through the incorporation of advanced high-resolution DEMs, such as GLO30, providing a modern and thorough evaluation of DEM accuracy specifically for Kazakhstan. What is new is a detailed analysis of the impact of terrain features (plain, hilly, mountainous) on modeling accuracy. This approach advances beyond previous assessments, delivering new and significant insights into the performance of contemporary DEMs. Practice value. The practical value of the results obtained consists in issuing recommendations regarding the possibility of using the studied DEM for the regions of Kazakhstan which differ among themselves in terms of landscape characteristics. The findings indicate that COPERNICUS and ALOS DEMs are highly suitable for precise geoid modeling in southern Kazakhstan. These models can significantly improve the accuracy of local geoid models, benefiting applications in geospatial science and engineering.

Purpose. To assess the state of budget financing of Ukrainian HEIs, determine their funding structure, and identify prerequisites for developing hybrid financing as a tool for stability and strategic development. Methodology. Dynamic and structural analysis, the Hirschman-Herfindahl index (HHI(DI) and such methods as quantitative, arithmetic mean, limit values, graphic, visualization, and system methods were used in the research process. The practical testing of research hypotheses was carried out on the basis of a comprehensive approach to the financing of HEIs of Ukraine and a panel sample of 35 universities, which takes into account rating indicators, industry and regional aspects. Findings. Transformation processes at various levels are linked to trends such as reduced budget funding, structural changes, staff and student migration, decreased demand for additional services, and military factors, creating prerequisites for hybrid university funding. The article identifies conditions for hybrid financing, highlights negative trends in HEIs budget financing –including systemic underperformance and inflation impacts – and analyzes income diversification in Ukrainian universities using the HHI(DI). Limiting and average values were determined using the quantitative method, which made it possible to classify universities into sustainable (HHI(DI)  0.55) and risky (HHI(DI) > 0.55) ones; tendencies towards a slight diversification of universities’ incomes are revealed; a conceptual model is proposed of hybrid financing of universities to expand their financial autonomy, based on cooperation between university management, stakeholders, and staff core, with the aim of creating value propositions which satisfy the needs of stakeholders and generate cash flows; a new approach to the division of hybrid financing tools into three groups is proposed: passive or image-based, active-intellectual, and passive-innovative ones. This approach is innovative in the development of financial strategies for universities. Originality. New tools for making management decisions aimed at ensuring financial stability and developing financial strategies for universities are proposed. In particular, they include an original approach to the classification of universities into sustainable and risky ones based on the value of the HHI; the conceptual model of hybrid financing of universities, which promotes the expansion of their financial autonomy; the innovative approach to the division of hybrid financing instruments into three categories: passive or image-based, active-intellectual, passive-innovative. Practical value. The study’s results can be used to make management decisions on expanding financial autonomy of universities. The introduction of the conceptual model of hybrid financing will contribute to the diversification of income, increase in financing, as well as ensuring financial stability and strategic development of universities.

Optimal Buy-Back Price For Supply Chain Coordination
Authors: Faludi Tamás
Published: October 2024

Supply chain coordination is a very popular topic in the 21st century. Supply chains involve a large number of members, and in order to work together effectively, it is necessary to coordinate the value creation processes of these members in some way to ensure that the 'customer is king' principle is upheld and a high level of customer satisfaction is guaranteed. Because of the large number of members, chains are now considered as networks in the literature. Many opportunities are available to achieve the right level of coordination between members. One possible coordination tool is the contracts. This paper is focused on the chance of coordination improvement with the help of one interesting contract, which is the buy-back contract. This type of contract has a very sensitive point: the buy-back price. If this value is too low or too high, it results in negative influences on one or both parties. That is the reason why it is very important to determine an optimal buy-back price. The paper includes a model, which can help to understand the influencing factors of buy-back price, and with the help of this, an analytical model can be presented for the calculation of the optimal buy-back price.

Published: October 2024

This research aimed to determine whether there is an association between financial performance and chief executive officer (CEO) remuneration when South African banks are sampled. A quantitative research approach was applied using a descriptive research design. The research included a data range spanning over 10 years. Financial data were collected through the Integrated Real-time Equity System (IRESS). Multiple regression testing was performed using the Statistical Package for Social Science (SPSS). Correlation coefficients were measured, and multiple regression models were constructed. This study found that cashflow per share, market price per share and liquidity ratios were often identified as predictors of CEO remuneration. This research contributed to the body of existing knowledge by demonstrating that the remuneration paid to South African bank CEOs can be predicted by means of selected financial ratios. Limitations included that the census was small and only consisted of eight banks in total. This limitation was accommodated by expanding the time frame for data collection.

Objective: Evaluate the different anesthetic practices in the management of incomplete abortions. Materials and Methods: Our study is descriptive in a retrospective approach on; in six hospitals in South Kivu in DR Congo and data were collected then entered then encoded in Microsoft Excel software (preliminary analysis of the data or statistical description of the variables) then they were analyzed in Epi Info software. Results: The age group between 26 to 35 years was the most represented with an average of 30±7.5 years, the weight for the majority of them varied in the group from 60 to 69 or 60.4%, the majority came from the health zone and represented 94.6%, they were a priori housewives and Catholics and represented 55.4%. We noted narcosis or hyponosis (propofol + Fentanyl followed by Ketamine + Diazepam + Atropine) with a very high frequency at 97.5%. Many patients did not have any complications during their interventions and this would be estimated at a rate of 92.5%; all remaining complications represented 7.5%, i.e. respectively: Desaturation, hypotension and Vomiting. The factors correlated with morbidity and mortality were ASA class and complications with a significant difference because their P value is < 0.001. Conclusion: The current recommendations in terms of ECP for incomplete abortions are respected in the hospital structures of South Kivu but as elsewhere, there is no predominant anesthetic technique hence the need to think about a more effective and more effective anesthetic technique. comfortable for patients and practitioners in terms of management of incomplete abortions than the techniques currently practiced.

Authors: Al Habsi Sundus , Osama Mazin , Muzaffer Rahil , Al Farii Humaid
Published: October 2024

Septic arthritis is an infection to one joint or more that mainly happens after a hematogenous spread of an infection causing inflammation to the joint. Large joints such as hip and knee are more commonly affected, however, septic arthritis can happen in any other joints such as shoulders and ankles. Staphylococcus aureus is the most frequently isolated pathogen in this condition; however, other bacteria, viruses, fungi, and mycobacterium can also cause septic arthritis. Haemophilus influenzae type b (Hib) is the most common subtype of Haemophilus influenza and is primarily affecting children and those with compromised immune systems. Haemophilus influenza usually causes lower respiratory tract infections, including pneumonia. In addition, they can induce numerous other severe infections, such as bacteremia, empyema, meningitis, cellulitis, and septic arthritis. The Hib conjugate vaccine has significantly reduced the incidence of Hib infections and is effective in protecting against capsular polysaccharide type b. the CDC recommends administering a conjugate Hib vaccine series beginning at age 2 months, or 6 weeks followed by boosters at age of12 to 15 months. In this article, we are reporting a unique case of hip septic joint in a fully vaccinated teenager, and it is the first case reported in the literature to our knowledge.

Background: Postural orthostatic tachycardia syndrome (POTS) is a clinical syndrome diagnosed when orthostatic intolerance and tachycardia appear in the standing position. POTS significantly impairs patients' quality of life. Aim: To report the symptoms, anamnestic and clinical elements, findings in the Tilt Test (HUT), evolution and treatment of POTS patients with a follow-up from 8 months to 28 years. Material and Methods: We reviewed from march 1996 to june 2024, 1269 HUT exams in our laboratory. Those reports in which orthostatic postural tachycardia and symptoms compatible with POTS appeared, were selected for analysis. Results: We identified 25 patients (2.6% of all positive Tilt test reports) with compatible signs and symptoms. Most patients complained of orthostatic intolerance, dizziness and frequent fainting. There was a delay of 8 -10 years between the onset of symptoms and the time of diagnosis. Orthostatic tachycardia and symptoms occurred on average after 3.5 and 5.2 minutes, respectively, when staying in the standing position. Our patients had a high frequency of syncope or presyncope in their families (60% frequency) and hypermobility joint syndrome (64% prevalence). 40% of the patients reported relief of their symptoms after being treated (most of them with fludrocortisone). Most patients that reported little or no relief, did not use medications or were treated for a short period. Conclusions: POTS is not common but significantly impairs the quality of life of those who suffer from it. We found a clear association with joint hypermobility syndrome, an excessive venous pooling during standing and a family history of syncope or lipothymia. Best treament is with fludrocortisone alone or in combination with midodrine.

A parada cardiorrespiratória (PCR) é uma emergência médica com alta taxa de mortalidade, e sua gestão eficaz é crucial para a sobrevivência e recuperação dos pacientes. Este estudo teve como objetivo revisar e descrever os cuidados de enfermagem na unidade de emergência durante e após a PCR, com base em uma revisão narrativa da literatura. Utilizando dados de artigos científicos publicados entre 2014 e 2023, o estudo enfatizou a importância do reconhecimento precoce dos sinais de PCR, a execução adequada das manobras de reanimação cardiopulmonar (RCP) e o manejo dos cuidados pós-PCR. Os resultados evidenciaram que o sucesso na reanimação está diretamente ligado à realização eficiente das compressões torácicas, à desfibrilação imediata e à administração precisa de medicamentos. A monitorização contínua e o suporte psicológico para familiares também são essenciais para um atendimento de qualidade. O estudo conclui que o treinamento contínuo e a atualização das diretrizes de RCP são indispensáveis para a melhoria dos desfechos clínicos e a redução das sequelas e da mortalidade associadas à PCR.

A osteonecrose é uma alteração patológica óssea em que ocorre a necrose do tecido ósseo, sem infecção prévia. A osteonecrose dos maxilares associada aos bisfosfonatos (BFS) foi descrita pela primeira vez em 2003 por Marx. No entanto, a nomenclatura atual foi modificada pela American Association of Oral and Maxillofacial Surgeons (AAOMS) para osteonecrose dos maxilares relacionada a medicamentos (MRONJ), mantendo a descrição como um efeito de várias outras classes de medicamentos. Este estudo teve como objetivo realizar uma revisão narrativa de literatura sobre a patogênese da Osteonecrose dos Maxilares Induzida por Medicamento (OMIM), alterações nos maxilares, diagnóstico e quais os tratamentos podem ser realizados, bem como as medidas de prevenção. Além disso, analisar e identificar quais os medicamentos que induzem a osteonecrose na cavidade oral e os procedimentos de risco para acometimento desta alteração. Como metodologia, foi realizada a busca dentro de diversos autores e referenciais sobre um tema específico com abordagem qualitativa. Foi realizado um levantamento de artigos pesquisados nas bases de dados Google Acadêmico, BVS com pesquisas correlacionadas ao tema osteonecrose dos maxilares causadas por medicamentos. Foram contemplados artigos dos anos de 2003 a 2023. Mais estudos sobre OMIM devem ser realizados, ainda assim, o acompanhamento periódico e a manutenção da saúde bucal realizada pelo um cirurgião-dentista e a inclusão deste profissional em uma equipe multiprofissional é primordial para diminuir as complicações que se acomete a cavidade oral.

Cuidado paliativo neonatal é um tema recente no Brasil e ainda há pouca literatura nacional disponível. Desta forma, o estudo objetivou descrever o perfil dos recém-nascidos que foram a óbito no período de janeiro de 2022 a dezembro de 2023, enumerar quantos receberam cuidados paliativos e comparar os que faleceram em UTIN e na sala de parto. Os dados foram obtidos por meio da revisão de atestados de óbito e de prontuários e a análise estatística realizada foi baseada em uma variedade de métodos, incluindo medidas descritivas e testes de hipóteses. Foram constatados 51 óbitos, com mediana de 775 g e IG mediana de 25 semanas. Prematuros extremos, nascidos vivos na faixa de abortamento corresponderam a 19,6% da amostra. O tempo de vida foi de até 24 horas em 61% dos casos. As principais causas finais de óbito (52,8%) estão relacionadas à síndrome do desconforto respiratório, prematuridade e asfixia. A instituição conta com protocolo de cuidados paliativos, sendo que a maioria dos pacientes (71%) não foram reanimados no momento do óbito, mas sim, oferecidos cuidados paliativos. Destes que receberam paliativos, 42% tinham um plano escrito de cuidados em final de vida. Ao compararmos os óbitos na sala de parto com os da UTIN, identificamos uma gestacional e peso inferiores, onde 44% estavam abaixo da zona de viabilidade, que é de 22 semanas. Os óbitos na UTIN tiveram mais planos de final de vida, devido ao maior tempo para atuação da equipe de paliativos.
