Hashimoto’s thyroiditis (HT) is a prevalent autoimmune disease. We investigated the relationship of peripheral blood long noncoding RNA-plasmacytoma variant translocation 1 (lncRNA-PVT1) and microRNA (miR)-146a levels with Th17/Treg-related cytokines in HT patients and their clinical significance. Correlations of PVT1 and miR-146a with Th17/Treg-related cytokines were analyzed, and its clinical value in diagnosing HT was assessed. Results showed reduced lncRNA-PVT1 and interleukin (IL)-10 levels and increased miR-146a and IL-17 levels in HT patients. lncRNA-PVT1 negatively interrelated with miR-146a, IL-17, IL-23 and IL-6, and positively interrelated with IL-10; miR-146a positively correlated with IL-17, IL-23 and IL-6, but negatively correlated with IL-10 in HT patients. The area under the curve (AUC) of lncRNA-PVT1 and miR-146a levels for diagnosing HT were 0.822 and 0.844, respectively (sensitivity 88.73% and 86.62%, specificity 67.02% and 69.15%, cut-off values 0.76 and 2.73), with their combined detections yielding a higher AUC. Patients with poorly expressed lncRNA-PVT1 and highly expressed miR-146a had elevated HT incidence. lncRNA-PVT1 and miR-146a levels were also found to be an independent influencing factor for HT occurrence. Our findings suggest that HT patients have low peripheral blood lncRNA-PVT1 expression and high miR-146a expression. lncRNA-PVT1 and miR-146a level changes were correlated with Th17/Treg cytokine imbalance and could be a potential diagnostic tool and independent influencing factor for HT.

Published: May 2024

Çok taşıyıcılı (MC) telsiz iletişim sistemlerinin en büyük dezavantajlarından birisi yüksek tepe-ortalama güç oranı (PAPR)’dır. Pek çok standartta kabul edilen dikgen frekans bölmeli çoğullama (OFDM) sistemi de bu dezavantajdan etkilenmektedir. Araştırma literatüründe MC telsiz iletişim sistemlerinin yüksek PAPR seviyelerini azaltmak için genlik kırpma (AC) ve filtreleme, kodlama, serpiştirme, ton rezervasyonu (TR), ton ekleme (TI), kısmi iletim dizisi (PTS) ve seçilmiş haritalama (SLM) teknikleri gibi pek çok yöntem sunulmuştur. Bunlara ek olarak, bu PAPR azaltma yöntemlerini kullanan MC telsiz iletişim sistemlerinin diğer performanslarının iyileştirilmesi amacıyla sistemlere uygulanan hızlı Walsh Hadamard dönüşümü (FWHT) ve ayrık dalgacık dönüşümü (DWT) gibi dönüşümlerde sunulmuştur. Bu çalışmada, MC telsiz iletişim sistemlerinin hem bit hata oranı (BER) performansını hem de PAPR başarımını iyileştirmek için PTS ve AC tekniği ile Lazy dalgacığını kullanan Lifting dalgacık dönüşümünün (LLWT) birleştirilmesi önerilmektedir. Bu makalede, ilk defa bu çalışmada önerilen PTS ve AC tekniği ile LLWT dönüşümünün birleşimi olan LLWT-PTS-AC yöntemi, MC telsiz iletişim sistemlerinin dezavantajlarını ortadan kaldırmak için klasik OFDM dalga formuna uygulanmıştır ve kayda değer sonuçlar elde edilmiştir. Sonuçlar incelendiği zaman, klasik OFDM sisteminin PAPR ve BER başarımlarının tatmin edici ölçüde arttığı görülmektedir.

Pharmacologic Treatment of Type 2-High Severe Asthma
Authors: Bosi Annamaria , Simeone Maria , Ghinassi Federica , Baroncini Serena , Ruggieri Valentina , Beghe Bianca
Published: May 2024

Asthma is a common and heterogeneous disease whose treatment has considerably changed over the last decades. While inhaled therapies based on inhaled corticosteroids and long acting β2 agonists are effective in controlling asthma in the majority of patients, about 5% of asthmatics poorly respond to inhaled steroids or inhaled steroids/long acting β2 agonists combinations. These patients are affected by “severe asthma”, which is associated with need of oral corticosteroids, progression of the disease, increased use of healthcare services, deterioration of quality of life, and a significant economic burden on society. Asthma is no longer considered a single disease, but a respiratory syndrome with complex biological network of distinct and interrelating inflammatory and remodeling pathways (endotypes) that are associated with different clinical manifestations (phenotypes) both in the lungs (asthma) and other organs (e.g. nose and skin). Severe asthma endotypes may be broadly regarded as Type 2-high and Type 2-low, a model that has become central to asthma management with the development of novel treatments for the Type 2-high endotypes. The hallmark feature of Type 2-high asthma is eosinophilic inflammation, often associated with increased serum IgE, increased exhaled nitric oxide (FeNO) and blood eosinophilia. The discovery of the main key drivers of Type 2-high inflammation (IgE, cytokines such as interleukin IL-5, -4 and -13) enabled the development of new biological agents directed towards specific molecular targets. These advances have shifted the existing paradigm “one drug fits all” to “patient-tailored” novel therapies. The monoclonal antibodies direct to IgE (omalizumab), IL-5 and IL-5 receptor (mepolizumab, benralizumab, reslizumab), and to the α chain of the IL-4 and IL-13 combined receptor (dupilumab), and more recently, to the thymic stromal lymphopoietin (tezepelumab) have been shown in both clinical trials and real-life studies to control symptoms, reduce asthma exacerbations and improve lung function in severe asthmatics not controlled by full inhalation therapies. More recently, the Single Inhaler Triple Therapy (SITT) containing inhaled steroids, long acting β2 agonists and muscarinic antagonists has been developed, slightly improving the effectiveness/safety of the inhalation therapy. This report aims to review available therapeutic opportunities for patients with severe asthma focusing on patients with Type 2-high severe asthma and how to position these new therapeutic alternatives in clinical practice.

Money and Uncertainty of Outcome in Modern Sports Based on the Example of Football
Authors: Metelski Adam
Published: May 2024

One of the fundamental aspects of professional football is competition, which not only captivates fans but also drives its economic success. Money undeniably plays a significant role in determining sports outcomes, as clubs with larger budgets often possess better players. This article aims to examine the relationship between the market value of football clubs’ squads and their performance in the top 15 European leagues, as per the UEFA ranking. Among these leagues, Manchester City boasts the highest players market value in Europe, estimated at 1,110 million EUR, accounting for a mere 11.21% of the total market value of all English Premier League players. In summary, over the course of the last five seasons, out of 75 possible champions across the analysed leagues, the team with the most expensive squad has emerged victorious on 54 occasions. Consequently, it prompts consideration as to whether any measures should be taken to foster greater balance and to reduce the domination of wealthy teams in national football leagues.

Authors: Kona Prabhavathi , Rao P. Jagan Mohana , Rao R.G.S. , Latha V. Swarna , Bharathi Y.
Published: May 2024

Background: Groundnut is one of the most important oilseed crops and also a good source of proteins, carbohydrates and fibre. Conventionally, groundnut cultivation also need good amount of commercial nitrogen fertilizers which are found to be not efficiently and effectively utilized by the plants, also lost due to leaching and so, causing severe ecological damage. However, our study of priming groundnut seeds with nanofertilizers have reduced the dosage of fertilizers as well as increased the yields. Methods: A two-year field experiment (2020-2021) was carried out to evaluate the effect of nano fertilizers (NF) (phosphorus, zinc, and iron) seed priming and NF foliar spray on the growth, yield, and seed quality characteristics of groundnut var TG-37 A. Groundnut was chosen as the testcrop and seeds were primed with nanofertilizers as well as standing crop is foliar sprayed with nanofertilizer at pre-flowering stage. The effect of nanofertilizers on test crop was evaluated on seed germination, seedling vigor, plant growth, flowering, chlorophyll content, pod yield, oil content and protein content. Result: The results indicated that in both the years, NF seed primingandfoliar sprays treatments showed higher seed germination and seedling vigor aided in early establishment in soil, which manifested by higher plant height, early flowering, higher leaf chlorophyll content, 100-seed weight and shelling percentage. Pod yield per plant was 30.1% and 33.0% higher in 2020 and 2021, respectively, as compared to the control. In both years, the application of nano fertilizers considerably boosted the oil and protein content compared to the control (31.5% and 28.9% for oil, 33.1% and 30.0% for protein). Thus, it is concluded that nano-fertilizers considerably improved growth, yield and quality of groundnut.

Authors: Pervez A.K.M. Kanak , Bhuiya Rejvi Ahmed , Amin Md. Ruhul , Prodhan Foyez Ahmed , Salahin Mesbaus
Published: May 2024

Background: The study was conducted to ascertain the farmers’ willingness to stop tobacco cultivation, identify the determinants of farmers’ desire to stop tobacco cultivation and discover alternate food crops farmers are interested in cultivating in Bangladesh. Methods: A total of 377 tobacco growers in most tobacco-growing areas in Bangladesh were surveyed using a sample randomization technique using binary logistic regression and the factors influencing farmers’ choice to produce tobacco were examined. Face-to-face structured surveys from January 2022 to March 2023 were conducted in Mirpur Upazila (Sub-district) from Kushtia and Gangachara Upazila from Rangpur districts of Bangladesh. Result: Only 46.4% of the farmers are willing to stop tobacco cultivation. The key determinants for their willingness to stop growing tobacco are education level, tobacco cultivation experience, incentives and organizational participation of the tobacco farmers. In the farmer’s view, maize, mustard, potatoes and lentils are the most suitable food crops to replace tobacco. To shift tobacco farmers to growing food crops, the Government should increase the farmers’ educational level and offer inputs, loans and other incentives to promote alternate crops like maize, mustard, potato and lentil.

Authors: Haryuni H. , Wahid M.N. , Priyadi S. , Aziez A.F. , Maryanti I.E.
Published: May 2024

Background: The successful growth and development of the vanilla plant are supported by the availability of soil nutrients that are absorbed by the plant roots. Natural fertilizers derived from plant waste easily decompose in the soil so that they are more quickly absorbed by roots and stored in plant cells. The purpose of this study was to determine the effect of eco-enzymes and husk charcoal on the growth of vanilla seedlings. Methods: This study was designed using a complete randomized block design. The first factor was eco-enzyme (without eco-enzyme and with eco-enzyme 15 ml/plant), namely E0 and E1, the second factor was the husk charcoal dose (0, 5, 10, 15) g/plant, P0, P1, P2, P3. Data were analyzed using ANOVA analysis of variance with Duncan’s multiple range test (DMRT) with a significant difference of 5%. The results showed that the best vanilla growth was obtained by treating it with 15 ml/polybag eco-enzyme and 15 g/polybag coconut shell charcoal (E1P3). Result: The plant height reaches 79.67 cm, the number of leaves reaches 12.67 strands and the width reaches 405.42 mm. The fresh weight of the plants reached 71.33 g, the dry weight of the plants reached 28 g, the fresh weight of the roots reached 8.6 g, and the dry weight of the roots reached 1.27 g. Microscopi observation showed that eco enzymes and coconut shell charcoal infected the roots and filled the tissues, then played a role in increasing the growth of the vanilla seedlings.
Efficient Faba Bean Leaf Disease Identification through Smart Detection using Deep Convolutional Neural Networks
Authors: Jeong Hie Yong , Na In Seop
Published: May 2024

Background: Legumes, such as lentils, field peas, Faba beans and chickpeas, are high in vitamins, fiber, important minerals and protein and can help avoid obesity and cardiovascular illnesses. They also contribute to ecosystem services, such as nitrogen fixation and resilience to environmental stresses. Despite a 60% increase in global pulse production from 2000 to 2021, a demand-supply gap, especially in South Asia, raises concerns about nutritional access. Since illnesses are currently an issue to the food security of faba beans, machine learning is required for efficient disease identification. Methods: This research employs Convolutional Neural Networks (CNNs) for robust Faba bean leaf disease identification. The CNN model is trained with diverse images representing specific diseases. The study focuses on diseases like Chocolate Spot, Faba Bean Gall, Rust and Healthy leaves. Image processing involves resizing, grayscale conversion and labeling. The CNN architecture includes eight convolutional layers, four max-pooling layers and three dropout layers. The model is trained using 80% of the dataset, validated using 20% and tested for accuracy. Result: The CNN model achieves an accuracy of 99.37% during training and 89.69% during validation after 75 epochs. Confusion matrix and classification report illustrate the model’s performance. It shows high precision, recall and F1 scores for each class, indicating balanced performance. Chocolate Spot and Rust exhibit the highest precision and F1 scores. The overall accuracy is 91%, comparable to other studies on Faba bean disease detection. The study presents a CNN-based disease identification system for Faba beans, demonstrating high accuracy and balanced performance across different diseases. The model’s effectiveness is comparable to other advanced techniques. The research highlights the potential of machine learning in optimizing disease management for Faba beans. Future work could explore a broader range of diseases and incorporate hybrid machine learning algorithms for further improvement.

Numerical Analysis of Airflow in Trachea Affected by Thyroid Cancer Using Finite Volume Method
Authors: Fatahillah Arif , Jannah Miftahul , Setiawani Susi , Setiawan Toto Bara , Kristiana Arika Indah
Published: May 2024

The study aims to analyze the airflow in the trachea due to thyroid cancer. Thyroid cancer is a cancer that attacks the thyroid gland. The thyroid gland is located in the neck below the Adam's apple. In general, thyroid cancer causes stenosis of the trachea due to cancer compression of the tracheal wall. This problem is solved using the finite volume method with SIMPLE (Semi Implicit Method for Pressure Linked Equation) discretization. This method is well suited for the discretization of irregularly shaped fluid flows. The software used is Matlab and Ansys Fluent. Matlab is used to compute numerical solutions and display graphs, while Fluent is used to visualize the air flow. The result of this study is that the greater the percentage of stenosis, the velocity of the airflow is faster and the pressure of the airflow is lower. The most critical condition for respiratory power loss is when the airflow velocity exceeds the normal limit, i.e. when the narrowing is more than 50%, the initial velocity is more than 0,1 m/s.

Authors: Susetyo Budi , Fitrianto Anwar
Published: May 2024

Missing data may occur in various types of research. Regression and multiple imputation by chained equations (MICE) are two methods that can be used to estimate missing data in panel data types. This study aims to compare the accuracy of the missing panel data estimation using the regression and the MICE methods. The data used in this study are 161 random samples of senior high schools and vocational schools in DKI province for the year 2016-2020. Based on the results of the Chow test, Hausman test, and Lagrange Multiplier test on panel data regression, it shows that the appropriate model for the student-teacher ratio (X5) is random, the percentage of teachers who have an educator certificate (X6) is a fixed model with the specific effect of individual school and time, while the percentage of teachers who hold a bachelor degree (X7) is a fixed model with the specific effect of individual. Based on this model, the estimation of missing data is then carried out. The accuracy of the missing data estimation was carried out by comparing the MAPE, MAE, and RMSE values. The results show that the MICE method is quite good for estimating missing data at X5, quite feasible for estimating X6, and very good for estimating missing data at X7. In general, MICE is more accurate than panel data regression

Un Análisis de la Efectividad de las Herramientas Macroprudenciales aplicadas en el Perú durante el periodo 2011-2021
Authors:   , Izaguirre Giraldo Vivian
Published: May 2024

El objetivo de la investigación es examinar la efectividad de la política macroprudencial en reducir el riesgo de insolvencia de los bancos en el Perú durante los años del 2011 hasta el 2021. Las herramientas macroprudenciales que se analizan son los requerimientos de capital, los requerimientos de encaje en moneda nacional, en moneda extranjera y las provisiones dinámicas. Los resultados sugieren que la política macroprudencial ha sido efectiva en disminuir el riesgo de insolvencia de las entidades bancarias peruanas, incluso en un periodo de estrés como el del Covid-19. Los requerimientos de capital y los requerimientos de encaje tanto en moneda nacional como en moneda extranjera tienen significancia estadística. Sin embargo, sucede lo contrario con las provisiones dinámicas, lo que se debería a que estas solo han sido requeridas durante un periodo breve, porque las condiciones de activación dependen del ciclo económico y no del ciclo financiero. Además, se encuentra que algunas características de los bancos originan que estos se encuentren menos expuestos al riesgo de insolvencia, tales como su nivel de actividad y el ratio de capitalización. A diferencia de lo que se encontró en el análisis previo a la ocurrencia de la pandemia del Covid-19, el tamaño del banco y la estructura de financiamiento no son variables que influyeron en la estabilidad financiera de los bancos.

El papel de la publicidad a la hora de abordar el acoso sexual en línea: la campaña de Pilsen centrada en los hombres durante COVID-19
Authors:   , Gamarra Rojas Gabriela
Published: May 2024

Durante la pandemia, las marcas han repensado su comunicación publicitaria en torno a la crisis global, mientras las personas se sumergen aún más en el mundo virtual. Es importante estudiar estos cambios porque el aumento en el uso de Internet ha llevado a una profundización de comportamientos negativos por parte de los hombres, como el acoso sexual en línea hacia las mujeres, que es un problema globalmente dañino. Por ello, es fundamental prestar atención a este comportamiento y comprender la percepción que tienen los hombres sobre este problema que perjudica a su propio género. En este contexto, se analiza la estrategia de marketing social como una herramienta para cambiar el comportamiento o pensamientos de una audiencia hacia un problema social.

The modernization of democracy further clarified the central position and role of political parties in the political system and statehood. This kind of central position and role in one hand can have a positive impact on the functioning of the democratic system and at the same time may have a negative impact if the working of the democratic system within the internal political parties is not addressed. This paper attempts to analyse integratively with the purpose of constructing and assessing the level of internal democracy of political parties in Indonesia. This research is doctrinal legal research with qualitative and quantitative methods, the data is sourced from primary, secondary legal materials, and non-legal sources. An important finding in this study is the formulation of the internal-party index in Indonesia, which is then attributed to a independent variable obtained from 9 (nine) political party data. The results of these findings are then used to assess the level of internal democracy of political parties through classification into five (5) levels, including Most Democratic (SD), Democratic (D), Moderate Democratic (CD), Non-Democratic (TD), and Most Undemocratic (STD). According to the assessment, only 2 parties were categorised as D, including Partai Amanat Nasional (PAN) and Partai Demokrasi Indonesia Perjuangan (PDIP). Meanwhile the others were in the CD category.

The Role of Teachers in Instilling Sedulur Sikep (Samin Tribe) Values in Early Childhood
Authors: Rosbiyarti Ayu , Fadjryana Fitroh Siti
Published: May 2024

The role of a teacher is an indispensable aspect of the education world, particularly in fulfilling the national educational process standards. The teacher's role in promoting character education can be tailored to the cultural wisdom of a specific region. With the advancement of technology and changing times, the teacher's role in education may no longer appear as prominent. Consequently, teachers often carry out their duties without emphasizing their role as educators. This research employs a qualitative case study approach using Miles and Huberman's model. The findings of this study indicate that teachers function as guides and supervisors in the growth and development of children. They oversee the thoughts, words, and behaviors of both students and themselves, monitor the assessment results, and work on improving the behaviors, thoughts, and words of both students and teachers. The implementation of Sedulur Sikep character teachings by teachers involves three core character teachings: (a) "Angger-angger pratikel" (ethical behavior): Encouraging honesty in everyday life and teaching students not to harbor jealousy or greed towards their peers. (b) "Angger-angger pangucap" (language usage): Promoting the use of Javanese Krama Inggil when communicating with peers or teachers. (c) "Angger-angger lakonan" (patience and resilience): Advocating a patient, resilient, and composed approach to handling various challenges and issues. This research contributes to the understanding that cultural character plays a significant role in shaping the values and behaviors of individuals.

Slowdown of typhoon translation speed and its links to the storm poleward migration
Authors: Feng Xiangbo
Published: May 2024

Detecting and interpreting long-term changes in typhoon translation speed in observations remains challenging, contrasting with the increased confidence in the poleward migration of typhoons. Here, I show a significant relationship between the basin-wide translation speed and the latitudinal position of typhoons in the western North Pacific over 1980–2023. There are two key findings. First, because typhoons move faster at higher latitudes, the significant poleward migration (80 km/decade) increases the yearly basin-wide translation speed by 5% over the period. This effect reduces the detectability of a slowing trend in typhoon translation speed. Second, the basin-wide translation speed solely contributed by regional translation speed has significantly slowed by 18%. The translation speed slowdown and the poleward migration are likely caused by the same climate drivers through the interconnected large-scale atmospheric circulation between the tropics and subtropics. My findings suggest exacerbated typhoon-related risk in the subtropical regions in a changing climate.
