Authors: Samsul Ma’arif
Published: August 2024

In this study it is expected to be able to reveal the relationship between creativity and student learning styles on mathematics learning outcomes. This is intended to obtain information about creativity and learning styles in relation to mathematics learning achievement. This study uses a quantitative research approach. The choice of this approach is because quantitative research is a type of research activity whose specifications are systematic, planned, and clearly structured from the start to the creation of the research design, both regarding research objectives, research subjects, research objects, data samples, data sources, and methodology. Validity is a measure that shows the levels of validity or validity of an instrument. An instrument that is valid or valid has high validity. Conversely, an instrument that is less valid means it has low validity. The instrument used in this research is a questionnaire. The questionnaire used is a closed questionnaire, that is, a questionnaire in which the questions/statements and alternative answers have been determined so that the respondent only has to choose the desired answer. The hypotheses that have been formulated will be tested with parametric statistics, namely by correlation and regression. The use of parametric statistics requires that the data for each variable to be analyzed must be normally distributed. Therefore, before testing the hypothesis, it will first be tested for normality of the data. The data normality test was performed using the chi square formula. Description of research results obtained from data collection with research instruments in the form of scores. This presentation includes the variables of creativity, learning styles, and mathematics learning outcomes which include the mean, median, mode, standard deviation, range of scores, minimum scores, and maximum scores. If Y denotes the dependent variable or learning outcomes variable in mathematics, X denotes the independent variable, Xi denotes the creativity variable, and X2 denotes the learning style variable then. Based on the output of the hypothesis testing using SPSS 16.0, the R square result was 0.068 which indicated that the price had a weak positive value, because the correlation value of 0.261 was not too large when compared to the individual correlation values between X1 and Y and X2 and Y. So that the value correlation only applies to the sample studied. Meanwhile, the value of Fcount <Ftable (2.342 <3.14) concluded that the result was not significant, which meant that this could not be applied to the entire population. From these results, there is no positive and significant relationship between creativity and learning styles to the matematic examintion result of student at MTs VIII level in Mataram Year 2015/2016.

Published: August 2024

The problem of vertical movement of water infiltrates the productive layer. This is often referred to as Water Coning. This water coning problem can occur because the actual production rate exceeds the critical production rate (the production rate that is allowed by a well to be produced free of coning), so that excessive suction results in a flow pressure gradient exceeding the gravitational force resulting in a breakthrough of the productive layer by water. Symptoms of water coning can be seen from surface symptoms, namely a significant increase in water content. The study wells are suspected of having water coning, this can be seen from the graph of the increase in water content and time, so these wells are analyzed further. As a further stage of this research by analyzing how much coning has been formed and also analyzing the development of the coning. Then determine the handling system for the coning problem. The purpose of this study is to evaluate wells that are suspected of having water coning using research methods that have been reviewed in their critical rate analysis, to analyze the evaluation of wells experiencing water coning in order to determine the factors causing it and determine a system to overcome the water problem of the coning.

Budidaya tumbuhan selada kali ini tergolong merupakan tumbuhan yang butuh akan sinar radiasi matahari. Terlihat ketika selada diletakkan pada suatu daerah yang kurang akan sinar radiasi matahari memiliki kondisi visualisasi yang lebih rendah dari segi diameter batang, luas daun serta kekokohan dari tanaman itu sendiri. Akan tetapi, tumbuhan yang tumbuh di daerah minim akan radiasi matahari juga memiliki keunggulan tersendiri. Hal ini dapat dibuktikan dengan rasa dan juga panjang batang dari tanaman tersebut. Keadaan ini dapat terjadi karena adanya beberapa faktor yakni adanya hormon auksin pada suatu tanaman serta adanya kandungan senyawa flavonoid. Terlepas dari setiap keunggulan dan kelemahan pada setiap kondisi tanaman, sinar radiasi matahari terbilang cukup berpengaruh dalam proses pertumbuhan serta pengembangan kualitas suatu tanaman, hal ini dikarena radiasi matahari nantinya akan juga berpengaruh pada tingkat suhu serta kelembapan udara yang nantinya akan sangat berpengaruh pada pertumbuhan tanaman itu sendri. Hasil ini juga didukung oleh banyaknya teori-teori yang mengungkapkan bahwasannya pengaruh radiasi matahari terhadap pertumbuhan serta kualitas suatu tanaman sangatlah besar. Dari penelitian-penelitan tersebut maka dapat juga diambil suatu kesimpulan bahwasannya pertumbuhan serta kualitas yang ada pada suatu tanaman dipengaruhi oleh banyak hal mulai dari suhu, kelembapan udara, lamanya penyinaran serta tingkat radiasi dari sinar matahari. Apabila salah satu dari itu semua tidak terpenuhi maka akan mengurangi tingkat kesegaran serta rasa dari tanaman itu sendiri.
Battery Management System Development for Electric Vehicles and Fast Charging Infrastructure Improvement
Authors: Yang Yu , Yeh Hen-Geul , Ortiz Cesar
Published: August 2024

The electric vehicle (EV) has become increasingly popular due to its being zero-emission. However, a significant challenge faced by EV drivers is the range anxiety associated with battery usage. Addressing this concern, this project develops a more efficient battery management system (BMS) for electric vehicles based on a real-time, state-of-charge (SOC) estimation. The proposed study delivers three modules: (1) a new equivalent circuit model (ECM) for lithium-ion batteries, (2) a new SOC estimator based on the moving horizon method, and (3) an on-board FPGA implementation of the classical Coulomb counting method for SOC estimation. The research team extends the traditional ECM by incorporating more functional features through the least absolute shrinkage and selection operator (LASSO). Then the first-order transfer function model identification and LASSO are iteratively executed to minimize the data fitting error. Given this model, the research team employs the moving horizon estimator (MHE) to determine the SOC by fitting the measured terminal voltage. Subsequently, the research team implements the SOC estimation scheme on an FPGA board. This hardware-in-the-loop simulation is demonstrated in this report step by step. The proposed research has broad societal impacts. It aligns with SB1 objectives in several ways. First, EVs with a more efficient BMS can improve their cruise range, reducing energy consumption and traffic congestion. Second, the resulting BMS can be applied in the solar-power and battery-assisted charging stations to make more reliable infrastructure in an age of sustainable transportation.

Vive-se em um mundo de velocidade e transformações onde o avanço da tecnologia cria novas possibilidades diariamente e representam desafios a quem queira acompanhar essa evolução tecnológica para criar regras e limites principalmente no que se refere aos direitos autorais. Os sistemas de inteligência artificial são capazes de criar obras de forma autônoma, com a mínima interferência humana, gerando dúvidas sobre a quem deve-se atribuir a autoria de tais obras e os respectivos direitos decorrentes dessa proteção. A metodologia adotada foi a jurídico-dogmática do tipo hipotético-dedutivo, com foco no direito positivo e análise do discurso normativo dentro dos limites do ordenamento jurídico. Foram examinados teorias e conceitos sobre autor, direito autoral e inteligência artificial. Também foi utilizado o tipo genérico jurídico-comparativo para identificar semelhanças e diferenças entre normas de sistemas jurídicos diferentes. Por meio de pesquisa qualitativa, foi realizado um estudo com grande quantidade de informações. Não há conclusões definitivas mas faz-se necessário garantir a proteção jurídica às criações da inteligência artificial até mesmo para incentivar a continuidade dos avanços tecnológicos na área.

Published: August 2024

OBJECTIVE: In this study, we developed an exercise training protocol for assessing both blood pressure dynamics and mRNA expression levels of purine receptors in various vascular tissues during physical activity. The objective is to assess the impact of exercise training on blood pressure regulation in spontaneously hypertensive rats (SHR) and purine receptors in vascular tissues. METHODS: Wistar Kyoto (WKY) and SHR rats were randomly allocated into sedentary (Sed) and exercise training (ExT) groups. Rats in the Sed groups were allowed unrestricted movement, whereas those in the ExT groups underwent a 16-week regimen of low- to moderate-intensity treadmill exercise. Throughout the intervention period, blood pressure measurements and body weight recordings were conducted. Additionally, mRNA expressions of purine receptors P2X1, P2Y1, and P2Y2 in renal artery (RA), internal carotid artery (Int), thoracic aorta (Aor), and caudal artery (Cau) tissues were assessed. RESULTS: In the Sed group, body weight of SHR rats was observed to be lower compared to the three other groups. Over the course of the exercise regimen, blood pressure in the ExT group of SHR rats reduced gradually, converging towards levels similar to those observed in WKY rats by the conclusion of the exercise period. Regarding mRNA expression patterns of P2X1 receptors across the four blood vessels, WKY and SHR rats demonstrated similar sequences, consistently displaying the highest expression levels in the Cau. Conversely, mRNA expressions of P2Y1 and P2Y2 receptors exhibited distinct sequences across the four blood vessels in both WKY and SHR rats. Notably, compared to the Sed group of WKY rats, mRNA expression of P2X1 receptor in the Int of SHR rats revealed an increase, while expressions in the Aor of WKY rats and the Cau of SHR rats decreased following exercise. Expression of P2Y1 receptor mRNA decreased across all four types of blood vessels in SHR rats. Post-exercise, P2Y1 receptor mRNA expression increased in the Aor, decreased in the Cau of WKY rats, and increased in the Int and renal artery (RA) of SHR rats. Conversely, expressions of P2Y2 receptor mRNA decreased in the Int and Aor of SHR rats. Except for the Aor of WKY rats, expressions of P2Y2 receptor mRNA increased in the other arteries of both rat types following exercise. CONCLUSION: Differences in the distribution of purine receptor subtypes among distinct arterial segments in both WKY and SHR rats were observed. Exercise training was found to enhance mRNA expression levels of P2Y receptors in these rat models. This finding implies that exercise training might reduce hypertension in SHR rats by bolstering the purinergic relaxation response.
A smart recycle sort network for garbage sorting
Authors: Zhu Tingrou
Published: August 2024

Garbage sorting contributes to resource recycling, mitigates environmental pollution, and promotes sustainable development. However, traditional garbage sorting methods typically require significant human labor and time resources, underscoring the necessity for automated solutions. While the convolutional neural network (CNN) has achieved significant success in garbage sorting, existing models still suffer from low computational efficiency and accuracy. In light of these challenges, this study proposes the smart recycle sort network (SRS-Net), a lightweight model with attention mechanism aimed at enhancing the efficiency and accuracy of garbage sorting processes. Lightweight networks reduce computational complexity and parameters, improving garbage sorting efficiency. We improve the ShuffleNet unit and introduce the lightweight shuffle attention module (LSAM) as the primary module of SRS-Net. On one hand, given the diverse shapes and sizes of garbage items, we replace the depthwise convolution (DWConv) in the ShuffleNet unit with heterogeneous kernel-based convolutions (HetConv) to accommodate this diversity. On the other hand, to better focus on important features of garbage images, we introduce shuffle attention (SA), a channel-spatial attention mechanism that considers the importance of inter-channel relationships and spatial positions. To validate the performance of SRS-Net, we conduct comparative experiments on two datasets, TrashNet and garbage dataset. The experimental results demonstrate that SRS-Net achieves an accuracy of 90.02% on TrashNet and 91.52% on garbage dataset, with FLOPs of 1262.0 M and Params of 9.6902 M. Our approach effectively facilitates automated garbage sorting and resource recycling.
Integrating word embedding and topic modeling for sentiment analysis: A case study on the social mood on economy
Authors: Bruno Mauro , Catanese Elena , De Cubellis Massimo
Published: August 2024

In recent years, textual analysis and embedding spaces have become essential and complementary tools for sentiment analysis in National Statistics Institutes’ research, owing to their ability to summarize discussed topics effectively. Istat has developed an innovative tool, wordembox, which allows external users to explore the outputs of popular word embedding algorithms, such as Word2Vec and FastText. This tool enriches the analysis with a novel graph functionality, enabling users to discover clusters of words and facilitating implicit topic modeling.

This article focuses on Social Mood on Economy (SME) posts over a period in which the index recorded a strong downward trend: the first month of the Russia-Ukraine conflict at the beginning of 2022. We compare findings from wordembox with standard topic modeling techniques, including Bayesian Latent Dirichlet Allocation (LDA), Top2Vec, and BERTopic, recent methods that extract clusters from word embedding spaces. These techniques show coherent results, and their combined use in textual analysis may create a synergy that enhances the informative content of synthetic indexes such as ‘Social Mood on Economy Index (SMEI)’.
Analysis of the dynamics of the nomenclature of medicines for the treatment of mental and behavioral disorders in the government program «Affordable Medicines»
Authors: Костюк І. А. , Косяченко К. Л.
Published: August 2024

The number of patients with mental and behavioral disorders is growing rapidly in many countries around the world. Ukraine is not exception. The consequences of a full-scale war will cause severe mental trauma, as every 10th resident of our country now experiences depression, anxiety, and psychosomatic disorders that can last up to 10 years. All of this demonstrate the incredible relevance of comprehensive research to counteract the rapid increase in the incidence of mental and behavioral disorders, to find tools for effective treatment of this group of nosologies, and to find ways to improve the quality of life of patients.
The aim of the study was to analyze the dynamics of the nomenclature of medicines for the treatment of mental and behavioral disorders in the Government Program «Affordable Medicines» for 2021–2024.
To achieve this goal, we applied content analysis of regulatory legal acts using market research, as well as methods of comparative, statistical and economic analysis, as well as systematization and generalization.
The results of the content analysis of all editions of the List of Medicinal Products Subject to Reimbursement under the State Guarantees for Medical Care of the Population revealed a stabilization of the number of international generic and brand names presented in the Government Program «Affordable Medicines» (9 and 65 respectively). However, given the martial law situation in Ukraine, the nomenclature of this group of drugs needs to be expanded. It was found that the range of medicinal products under study is dominated by domestically manufactured drugs, their segment is 54.5%, formed by 11 Ukrainian pharmaceutical companies. The foreign share is represented by 9 manufacturing countries, the most represented among which is India (16.9%). The number of medicinal products with full and partial reimbursement was analyzed and it was found that each of the international generic names under study has at least 1 product subject to full reimbursement. However, it is necessary to increase the number of medicines that are dispensed to patients free of charge for each international generic name, as a significant number of Ukrainians have mental and behavioral disorders and need greater economic accessibility to this particular group of drugs under martial law.

Method for testing the stability of an autoregressive model of the vocal tract and adjusting its parameters
Authors: Savchenko V. V. , Savchenko L. V.
Published: August 2024

Within the framework of the traditional direction of research in the field of acoustic measurements, an autoregressive model of the vocal tract as a key link in the human speech apparatus is considered. The acute problem of ensuring the stability of the autoregressive model in systems with adaptation of its parameters to the observed speech signal of short duration is pointed out. To overcome this problem, the task was set of testing the stability of the autoregressive model and adjusting its parameters based on the results of this testing. The study is based on the author’s method of formant analysis of vowel sounds of speech through the synthesis of a recursive shaping filter in the free oscillation mode. To solve sated task, a method is proposed for testing the stability and adjusting the parameters of the autoregressive model of the vocal tract based on a two-stage algorithm for its transformation. At the first stage of transformation, the stability of the autoregressive model is tested using the impulse response of the shaping filter. At the second stage, if the stability of the autoregressive model is violated, its impulse response is modified by element-by-element multiplication by a variable exponential value that asymptotically converges to zero. A regular algorithm has been developed for recalculating the modified impulse response into an adjusted vector of autoregressive parameters at the second stage of transformation. Based on the results of experimental testing of the proposed method, it was concluded that guaranteed stability of the autoregressive model of the vocal tract has been achieved with minimal distortion in the frequency domain. The results obtained are useful in the development and modernization of automatic speech recognition systems, digital speech communications, artificial intelligence and other information systems that use data compression and speech coding based on an autoregressive model of the vocal tract in automatic speech signal processing.

The much-needed packaging materials are still dominated by synthetic plastics which are difficult to decompose and produce dioxin gas, thus polluting the environment and dangerous for humans. The solution is to use bioplastics. The study aims to determine the characteristics of bioplastics in the ratio (%)  of corn starch to corn flour: 100:0; 80:20; 60:40; 40:60; 20:80; and 0:100. The study used RAL, and descriptive analysis. Starch suspension with a ratio of 1:20 as much as 100g/run was heated at a temperature of 70-80oC for 30 minutes while stirring added with 10% PVA solution and 1 mL of glycerol heated and stirred for 10 minutes, degassed for 10 minutes, molded and dried at 50-60oC for 24 hours. The resulted bioplastics were then characterized for their water resistance, film thickness, degradation, tensile strength, elongation at break, and morphology. The results showed that the addition of corn flour increased water resistance, film thickness, degradation time, tensile strength, and elongation at break. The best results in this study were obtained at a ratio of 0:100.
