As doenças cardiovasculares no Brasil e no mundo configuram a principal causa de mortes. O uso de Anticoagulantes Orais (ACOS) é a modalidade terapêutica principal para a prevenção de complicações, como eventos tromboembólicos e hemorrágicos. A adesão ao tratamento anticoagulante é fundamental para a manutenção terapêutica adequada. Objetivos: elucidar através da revisão integrativa da literatura, os conhecimentos necessários para o autocuidado de pacientes anticoagulados. Metodologia: Trata-se de uma revisão integrativa da literatura realizada nas bases de dados BVS BIREME, WEB OF SCIENCE, PUBMED. Utilizou-se o recorte temporal dos últimos cinco anos, fontes primárias e avaliação dos níveis de evidência. Para a pergunta norteadora, a estratégia PICO foi adotada, P refere-se à população de estudo (pacientes em uso de ACOS); I de intervenção ou área de interesse (conhecimento); C de comparação com outra intervenção (não se aplica ao estudo proposto); e O desfecho de interesse (autocuidado). Elencou-se enquanto pergunta norteadora: Quais os conhecimentos necessários para o autocuidado de pacientes em uso de anticoagulantes orais? O período de coleta de dados foi realizado entre janeiro e fevereiro de 2024. A análise dos dados considerou a avaliação por pares, através da leitura do título, do resumo e do texto completo e classificação das publicações analisadas a partir do nível de evidência. Resultados: A pesquisa resultou em 6 artigos científicos. Constatou-se que os conhecimentos necessários acerca dos anticoagulantes orais, tais como mudança de estilo de vida, dieta, indicações e complicações da terapêutica, prática de atividade física e a inclusão dos familiares no cuidado interferem na adesão ao tratamento medicamentoso e no autocuidado de pacientes anticoagulados. Conclusões: Evidenciou-se a busca de informação e conhecimento como estratégia de autocuidado, além do déficit de práticas específicas de autocuidado no uso de anticoagulantes orais. Reforça-se o papel fundamental do enfermeiro frente ao educar em saúde como potencial elo de confiança e comunicação entre pacientes, cuidadores e familiares para o fortalecimento do autocuidado.

Na atual era de avanços científicos extraordinariamente progressivos, há uma necessidade de ampliação da informação aproximando e consolidando saberes, rompendo avanços e gerando novos conhecimentos. No que diz respeito à enfermagem como profissão, a produção do conhecimento científico precisa se adequar às necessidades do saber e fazer dos alunos, com a finalidade de desenvolver habilidades e consolidar conhecimento teórico-prático sobre o exame citopatológico. Objetivo: Desenvolver não só conhecimento teórico sobre a saúde da mulher mais o prático, como dinâmica de fixação de conteúdo e habilidade da coleta do exame citopatológico. Metodologia: Descrição do tipo relato de experiência vivenciada por estudantes do 6 período de enfermagem de uma universidade privada na cidade de Recife, PE. Resultados e Discussão:  A experiência se desenvolveu por meio de uma aula onde foi realizado uma dinâmica prática onde os alunos puderam além do conhecimento teóricos ter contato com a praticar da coleta do exame citopatológico tendo contato direto com os materiais (espéculo, espátula de Ayres e escova endocervical). Durante a aula foi proposto pela discente o uso de uma fruta, ameixa, como representação do colo do útero, o que facilitou o entendimento, da representação do colo do uterino. A introdução do espéculo na vagina até  o colo do útero ( ameixa), o uso da espátula de Ayres na região exocévice e seu giro de 360 graus, a coleta realizada com a escove endocervical na região endocévice e o  uso da lâmina para a identificação, realizado pós coleta do material foi algo realizado e discutido em aula onde cada aluno tiveram a oportunidade ter sua experiência prática, outro fator de extrema importância foi a análise clínica durante o procedimento para identificar odor, cor e textura do material coletado, outros assuntos como o não uso da escova em gestantes, pelos risco de aborto foram abordado. Durante a aula prática, mesmo com uma visão universitária pode ser observar que  mesmo entre as alunas do sexo feminino, havia pouco conhecimento sobre os benefícios do exame , e suas contraindicações. Considerações finais: A ação educativa promoveu conhecimento teórico e prática para alunos em sua formação profissional nas áreas de saúde, isso indica que dentro da sociedade contemporânea a enfermagem é hoje um dos grandes agentes contra o câncer do colo do útero, tantos nos programas de saúde da família ( PDF) quanto no programa de saúde nas escolas (PSE) ao assuntos de grande relevância a serem abordados , e os profissional da saúde são os principais agentes responsável pela promoção da saúde da mulher.

No sistema socioeducativo, os adolescentes entre 12 à 18 anos, e até os 21 anos em casos excepcionais, têm a oportunidade de terem acesso às atividades escolares, cursos de qualificação, acompanhamento médico e informação em saúde. Segundo Silva, Guisande e Cardoso (2018), as experiências sexuais ocorrem cada vez mais precocemente, neste sentido, a falta de informação pode levar a ter comportamentos que gerem riscos de infecções sexualmente transmissíveis (ISTs) e gravidez precoce. Nessa perspectiva foi utilizada a metodologia do “passa ou repassa” como forma dinâmica para auxiliar na educação em saúde. Objetivos: Relatar experiência vivenciada na Residência Multiprofissional de Atenção Básica e Saúde da Família da ASCES-UNITA, descrevendo a ação realizada no mês de dezembro de 2023 para os adolescentes em cumprimento de medidas socioeducativas da Fundação de Atendimento Socioeducativo (FUNASE) em Caruaru, Pernambuco. Relato da experiência: Foi realizado no mês de dezembro de 2023, no Centro de Internação Provisória (CENIP), primeiro setor de entrada e de caráter provisório no sistema socioeducativo, com o quantitativo de 6 adolescentes. A abordagem foi baseada no uso da passa ou repassa, com 15 perguntas referentes às ISTs como, por exemplo: “a camisinha é a única forma de prevenir as ISTs” “AIDS é o mesmo de HIV” “a transmissão ocorre por compartilhamento de objetos”, “as ISTs sempre apresentam sintomas”. Durante este momento, eram formadas duplas de adolescentes, e eles respondiam se a afirmativa era “verdadeira” ou “falsa”, e explicavam o seu entendimento sobre a pergunta realizada. Em seguida, foi feita a contextualização teórica da pergunta pelos profissionais residentes. Reflexão sobre a experiência: Foi observado a participação ativa dos adolescentes durante a aplicação das perguntas. Embora que eles não possuam o conhecimento teórico-científico, percebe-se que eles já possuem uma bagagem empírica sobre a temática, que contribuiu para o debate e para a troca de conhecimentos entre todos os envolvidos. Ainda, que a aplicação da dinâmica em pauta, por ter seu caráter lúdico e dinâmico, contribuiu para uma melhor aceitação dos adolescentes durante o encontro. Conclusões ou recomendações: A educação em saúde teve como intuito, levar conhecimento em educação sexual, principalmente, sobre as ISTs, enquanto estratégia de diminuição da continuidade da cadeia de transmissão e levando autonomia aos adolescentes para o autocuidado. Percebe-se que o uso de metodologias lúdicas e dinâmicas com adolescentes em medida socioeducativa, possibilitou uma efetiva participação, bem como, uma importante interação entre profissionais e estes usuários.

Segundo Belela-Anacleto, Peterlini, Pedreira (2017), atividades como higienização das mãos, entre outros cuidados à saúde são essenciais no processo de manutenção da saúde e prevenção de complicações. Entre as temáticas do programa saúde na escola (PSE), política intersetorial em um espaço privilegiado que abrange educação e saúde, a higienização das mãos é uma atividade prática e pode ser feita de forma lúdica na prevenção de parasitoses, doenças comumente encontradas no público infantil. Objetivos: Relatar experiência vivenciada na Residência Multiprofissional de Atenção Básica e Saúde da Família da ASCES-UNITA, descrevendo o PSE realizado no mês de abril de 2024 em uma creche municipal no município de Caruaru, Pernambuco. Relato da experiência: Foi realizado em uma das creches municipais de Caruaru, com 8 turmas de 20 crianças na faixa etária de 4 a 5 anos. Primeiro, foram feitas perguntas para as crianças, como exemplo: “porque lavamos as mãos” “o que tem nas mãos sujas” “qual o momento de lavar as mãos”, logo após houve a simulação gráfica em uma folha de ofício com o desenho de uma torneira e vários microorganismos para simular de forma lúdica para onde os microorganismos vão na lavagem das mãos, enquanto isso foi feito uma educação em saúde sobre hábitos da higienização antes e após ir ao banheiro, comer, tocar em dinheiro ou se sujar. Ao final, as crianças sujaram as mãos de tinta, como demonstrativo das mãos sujas e com bactérias e foram conduzidas para os lavatórios, onde foi demonstrado o passo a passo do procedimento correto da higienização utilizando água e sabonete líquido, onde foi observando novamente as mãos limpas, e reforçado a importância de mantê-las assim. Reflexão sobre a experiência: A temática foi trabalhada na importância da higienização das mãos, especialmente por ser um local de alta vulnerabilidade social e ausência de saneamento básico. A atividade realizada de forma lúdica chamou a atenção das crianças, fazendo com que as mesmas participassem ativamente do momento proposto. Essa forma favoreceu o entendimento das crianças sobre o assunto. Conclusões ou recomendações: A dinâmica utilizada foi efetiva para a atividade proposta, proporcionando um momento lúdico de educação em saúde na prevenção de parasitoses que ocorrem comumente pela ausência de cuidados à saúde.

Published: November 2024

The analysis of water infiltration channels requires significant time and cost when conducted through laboratory experiments. Alternatively, mathematical modeling followed by numerical method can be employed. The mathematical model of water infiltration in furrow irrigation channels takes the form of a boundary value problem, with the Helmholtz equation serving as the governing equation. The Dual Reciprocity Boundary Element Method (DRBEM) is a numerical method derived from the Boundary Element Method (BEM), utilized for solving partial differential equations encountered in mathematical physics and engineering. This research employs DRBEM to analyze infiltration in trapezoidal irrigation channels with root-water uptake across various homogeneous soil types prevalent in agricultural lands in each District/City of the Yogyakarta Special Region Province. The results demonstrate that DRBEM provides numerical solutions for suction potential, water content, and root water absorption for each soil type. It was found that sandy soil exhibits high water content but has a low rate of root water absorption. On the other hand, clayey soil has low water content but a higher rate of root water uptake. These findings indicate that sandy soil, such as those found in Sleman District and Yogyakarta city, are less efficient in water usage when employing the furrow irrigation system, whereas clayey soil, as found in Gunung Kidul regency, is more effective.

This study proposes a cluster analysis of provinces based on national food security data. The research objective is to determine provincial clusters based on food indicators which include rice harvest area, distribution of rice stocks, percentage of trade margin and transportation of rice distribution, percentage of average per capita expenditure, and total per capita consumption of rice. The source of observation data for the Rice Harvested Area by Province variable is the Ministry of Agriculture, Central Bureau of Statistics and Agriculture Services throughout Indonesia. This study uses data mining techniques in data processing with the K-Medoids algorithm. The K-Medoids method is a clustering method that functions to break down data sets into several groups. The advantage of this method is that it can overcome the weakness of the K-Means method which is sensitive to outliers. Another advantage of this algorithm is that the results of the clustering process do not depend on the order in which the dataset is entered. The k-medoids clustering method can be applied to food security data by province. From grouping the data obtained three clusters, with silhouette coefficient values for cluster 1, cluster 2, and cluster 3 respectively 0.33; 0.32; and 0.44. With the largest silhouette coefficient value obtained in cluster 3 and the cluster has entered into a strong cluster structure. The research results can provide information to the government about food security grouping data in Indonesia which has an impact on the distribution and availability of food in Indonesia.

Effectiveness of Machine Learning Models with Bayesian Optimization-Based Method to Identify Important Variables that Affect GPA
Authors: R Arifuddin , Syafitri Utami Dyah , Erfiani Erfiani
Published: November 2024

To produce superior human resources, the SPs-IPB Master Program must consider the factors influencing the GPA in the student selection process. The method that can be used to identify these factors is a machine learning algorithm. This paper applies the random forest and XGBoost algorithms to identify significant variables that affect GPA. In the evaluation process, the default model will be compared with the model resulting from Bayesian and random search optimization. Bayesian optimization is a method for optimizing hyperparameters that combines information from previous iterations to improve estimates. It is highly efficient in terms of computing time. Based on a balanced accuracy and sensitivity metrics average, Bayesian optimization produces a model superior to the default model and more time-efficient than random search optimization. XGBoost sensitivity metric is 25% better than random forest. However, random forest is 19% better in accuracy and 30% in specificity. Important variables are obtained from the information gain value when splitting the tree nodes formed. According to the best random forest and XGBoost model, variables that have the most influence on students' GPA are Undergraduate University Status (X8) and Undergraduate University (X6). Meanwhile, the variables with the smallest influence are Gender (X4) and Enrollment (X9).

Published: November 2024

This research aims to predict roof tile production trends at one of the roof tile companies in Kebumen to assist company management in determining and providing management recommendations for the tile production that occurs. A comparison of Single Moving Average (SMA) and Double Moving Average (DMA) Forecasting methods was used to better accommodate trends in roof tile production data optimally. Where the forecast is presented for several steps ahead, and is equipped with a value measuring the accuracy of the forecast using Mean Absolute Percentage Error (MAPE), on roof tile production transaction data over 60 months, namely January-December 2019 to January-December 2023 to produce a monthly forecast for predicting roof tile production with n-th ordo 2 and 4. The total sample of training data processed was 1,415,987 records which were roof tile production transaction data, as well as data in January 2024 as test data (to test the accuracy of the forecast). The results of testing the forecast results produced a MAPE calculation of 6.6% for SMA with n-th ordo 2, while for n-th ordo 4 it was 7.2%. The MAPE value for DMA is 6.3% for n-th ordo 2, while for n-th ordo 4 it is 8.2%, which means the accuracy level is very good, namely above 90%. Based on the MAPE results obtained, the DMA method with n-th ordo 2 is a suitable method for carrying out periodic forecasting for roof tile companies in carrying out the production process to maintain stability and avoid unexpected events.
Robust Continuum Regression Study of LASSO Selection and WLAD LASSO on High-Dimensional Data Containing Outliers
Authors: Daulay Nurmai Syaroh , Erfiani Erfiani , Soleh Agus M
Published: November 2024

In research, we often encounter problems of multicollinearity and outliers, which can cause coefficients to become unstable and reduce model performance. Robust Continuum Regression (RCR) overcomes the problem of multicollinearity by reducing the number of independent variables, namely compressing the data into new variables (latent variables) that are independent of each other and whose dimensions are much smaller and applying robust regression techniques so that the complexity of the regression model can be reduced without losing essential information from data and provide more stable parameter estimates. However, it is hampered in the computational aspect if the data has very high dimensions (p>>n). In the initial stage, it is necessary to reduce dimensions by selecting variables. The Least Absolute Shrinkage and Selection Operator (LASSO) can overcome this but is sensitive to the presence of outliers, which can result in errors in selecting significant variables. Therefore, we need a method that is robust to outliers in selecting explanatory variables such as Weighted Least Absolute Deviations with LASSO penalty (WLAD LASSO) in selecting variables by considering the absolute deviation of the residuals. This method aims to overcome the problem of multicollinearity and model instability in high-dimensional data by paying attention to resistance to outliers. Leverages the outlier resistant RCR and variable selection capabilities of LASSO and WLAD LASSO to provide a more reliable and efficient solution for complex data analysis. Measure the performance of RKR-LASSO and RKR-WLAD LASSO; simulations were carried out using low-dimensional data and high-dimensional data with two scenarios, namely without outliers (δ= 0%) and with outliers (δ= 10%, 20%, 30%) with a level of correlation (ρ = 0.1,0.5,0.9). The analysis stage uses RStudio version 4.1.3 software using the "MASS" package to generate data that has a multivariate normal distribution, the "glmnet" package for LASSO variable selection, the "MTE" package for WLAD LASSO variable selection. The simulation results show the performance of RKR-LASSO tends to be superior in terms of model goodness of fit compared to RKR-WLAD LASSO. However, the performance of RKR-LASSO tends to decrease as outliers and correlations increase. RKR-LASSO tends to be looser in selecting relevant variables, resulting in a simpler model, but the variables chosen by LASSO are only marginally significant. RKR-WLAD LASSO is stricter in variable selection and only selects significant variables but ignores several variables that have a small but significant impact on the model.
Dependency Model of the Exchange Rate with the Volume Export of Mining Products in Indonesia Using Copula
Authors: Rizki Kurniadi , Budiarti Retno , Purnaba I Gusti Putu
Published: November 2024

This research aims to analyze the dependence of the IDR-USD exchange rate on the volume of mining exports in Indonesia using the copula approach. This dependence is important to understand considering that the exchange rate and mineral exports have a direct impact on the country's economy which depends on foreign exchange from this sector. Mineral exports are one of the country's main sources of foreign exchange, while the exchange rate influences the competitiveness of exports on the international market. The mining products taken are iron and steel, copper and nickel, which are Indonesia's leading commodities. The copula method was chosen because of its ability to capture and model non-linear dependencies between variables, without considering the distribution of each variable. Copula makes it possible to model the marginal distribution of exchange rates and export volumes separately from their dependency structures, which is in line with the complex and dynamic nature of the Indonesian mining sector economy. The results show that there is no significant dependence between the exchange rate and the volume of commodity exports taken. Therefore, this commodity export volume policy will not have a significant effect on fluctuations in the IDR-USD exchange rate and vice versa. This article can be a recommendation for exporters to understand that export volumes do not need to pay attention to exchange rate fluctuations.

Published: November 2024

Credit risk assessment is crucial for financial institutions to ensure loan repayment. To enhance the prediction accuracy of creditworthiness and timely repayment, this research employs semiparametric structural equation modeling (SEM) to analyze the factors influencing credit repayment timeliness. The research was conducted to apply semiparametric SEM modeling to the timeliness of paying credit. Semiparametric SEM is structural modeling in which two combined approaches of parametric and nonparametric approaches are used. The analysis method in this research is semiparametric SEM with a nonparametric approach using a truncated spline. Truncated splines are chosen for their flexibility, ability to model complex relationships, continuity, interpretability, and strong performance in nonparametric regression tasks. The data in the study were obtained through questionnaires distributed to Bank X mortgage debtors and are confidential. The quetionnairs in the Likert scale, with five options. The study used 3 variables consisting of one exogenous variable, one intervening endogenous variable, and one endogenous variable. The results showed that: (1) the effect of capacity and willingness to pay variables on timeliness of payment is significant; (2) modeling the capacity variable on willingness to pay also produces a significant estimate; (3) the effect of the capacity variable on the timeliness of payment variable is not influenced by the willingness to pay variable as an intervening variable; and (4) the R^2 value of 0.763 or 76.33% indicates that the model has good predictive relevance. To continue to develop punctuality of paying credit, banks need to pay attention to the financial stability of consumers. Besides the financial stability, banks should pay attention to the sense of responsibility that customers have.

The first 3D model of the city of Zagreb was developed in 2008. Since then, the model has been improved and updated. Today, it is used for various purposes in the city planning and management. It is also publicly available to citizens through the ZG3D Web application. In this paper, an assessment of the existing 3D model is provided by considering different factors (i.e. consistency between models, standardization, data quality, data interoperability, data maintenance/governance, and use cases) that need to be tackled in order for the 3D city model to be further improved and used towards the creation of the digital twin and ultimately to support the smart city concept. The assessment considered some general criteria and also the 3D City Index assessment tool developed by the Urban Analytics Lab, National University of Singapore (NUS). The assessment results show that the existing model is used for various purposes, but to evolve towards a true digital twin, it must be improved.

The project phase is where the life-cycle of a building starts. The best decisions are made during the design or pre-project step. In terms of both economic resources and time, changes to specific design decisions made at this step are inexpensive compared to subsequent steps of architectural planning, not to mention the course of the construction's operation itself. The choices made during the design phase determine to a large extent whether the architectural design decisions of a building are achieved, whether the building and site can be used appropriately, and whether the project is economically viable. With BIM, building spatial planning is possible. As a result, architects can evaluate the proposed structure, its impact on the ecology, and the ecology's impact on the structure more comprehensively and at an earlier stage. This research proposes an energy modeling approach for the BIM-based spatial planning phase of a construction. The proposed method will result in an energy model for specific sites and building resolutions when utilized to create a spatial modelling for a construction. The energy model can then be used for new architectural creations. In this study, 36 different alternative scenarios were designed in terms of the rate of construction height to construction spacing, orientation factor, and form factor. With the help of BIM and GBS softwares, the energy consumption values of the alternative scenarios in cooling and heating load conditions were compared, and the alternative scenario with the minimum energy consumption was tried to be determined with spatial planning parameters.Ključne riječi
Engineering Training in the Structure of Higher Education and Professional Choice of Youth
Authors: Cherednichenko Galina A.
Published: November 2024

The structural elements of the university network of engineers’ training and its demand in different social groups of young people are analyzed using statistical data, monitoring and sociological research results. Recent shift in the choice by school graduates towards engineering specialties is associated, first of all, with the expansion of employment and career opportunities, as well as the growing attractiveness of advanced technical qualifications. The concentration of personnel training for the development of breakthrough technologies in top, selective universities is effected by combining investments from the state budget, large corporations, the development of innovative forms of education, in particular within the framework of the Advanced Engineering Schools project, as well as investments of families with high cultural and economic capital to ensure competitiveness of future students. Successful training in mass engineering education programs in regional universities, where numbers of budgetary admission places have been increased since 2022, is hampered by a keen shortage of well-prepared school students-applicants. The best results are shown under the practice of attracting target social groups of young people while maintaining value of technical labor, for example, in various forms of mobilization via the track “School-SPO-engineering training in higher education institutions”.
Abusive Supervision as a Social Phenomenon: Causes and Coping Strategies
Authors: Balabanova Evgeniya S. , Danilova Ksenia I.
Published: November 2024

The paper analyzes the phenomenon of abusive supervision (AS) in Russian organizations. The study is based on semi-structured in-depth interviews and a standardized survey of employees. The analysis demonstrates that half of the respondents had encountered various manifestations of AS at their current or previous jobs. The imbalance of power relations at workplace, employee’s socio-economic dependence on a supervisor are the core conditions of AS. Factor analysis results reveal 4 behavioral strategies of employees faced with AS – “neglect”, “exit”, “balance of power” and “loyalty”. A most effective strategy to reduce the manifestations of AS, according to respondents, was the “balance of power” strategy involving employees’ individual value enhancement and coalition formation.
Computer simulation of the total energy and the shielding function of a carbon molecule in the first order of perturbation theory
Authors: Koshcheev V. P. , Shtanov Yu. N.
Published: November 2024

Within the framework of a new approach to the problem of calculating the total energy of a diatomic molecule in the first order of perturbation theory, it is shown that the potential energy screening function is a solution to a diffusion-type equation in which the role of a time variable is played by the average square of the amplitude of collective oscillations of electrons per one degree of freedom. The total energy of two carbon atoms in the ground and excited states is calculated.
ПЕРСПЕКТИВИ ПРИЄДНАННЯ УКРАЇНСЬКИХ СПОТОВИХ РИНКІВ ЕЛЕКТРИЧНОЇ ЕНЕРГІЇ ДО MARKET COUPLING

The article is devoted to the study of the market coupling impact on the Ukrainian electricity market spot segments and the electricity market as a whole, taking into account its current state, where all stakeholders are constantly dealing with war risks, with no adequate possibility to hedge its own security of supply. It is emphasized that today the Ukrainian government and the electricity market stakeholders with the support of European partners and experts, are actively working on the implementation of the European Union energy regulatory acts, in particular, regarding the integration of the Ukrainian electricity market spot segments to market coupling – Commission Regulation (EU) 2015/1222 of 24 July 2015 establishing a guideline on capacity allocation and congestion management. It is noted that the implementation of other European Union energy regulatory acts was in 2018, which resulted in adoption of Law of Ukraine “On the Electricity Market” that established a playing field for competition of different stakeholders on electricity market and possibility of end consumers to be a part of the market as well, which all in its entirety introduced the liberalized model of electricity market Ukraine from July 01, 2019. The current state of the electricity market was analyzed, according to which it was concluded that the electricity market is in the stage of formation and development, and also needs measures to further liberalize the market, increase liquidity, introduce the financial instruments market and debt repayment. In stages, taking into account the selected basic rules and principles of market coupling, a study of the market coupling impact on the Ukrainian electricity market was conducted. As a result, positive conclusions were obtained regarding the improvement of liquidity and competition; ensuring optimal distribution of interstate power transmission line capacities as well as of obtaining an additional source for the development of interstate power transmission lines. It is emphasized that integration to market coupling can become an incentive for electricity market participants to use financial hedging tools to reduce credit and market risks.

Published: November 2024

This research develops a system for recognizing finger spelling gestures in Indonesian Sign Language (BISINDO) using Convolutional Neural Network (CNN). The objective of this research is to apply the Convolutional Neural Network (CNN) method to the BISINDO finger spelling gesture recognition system to improve its accuracy. The method employed is Convolutional Neural Network (CNN), an effective method for processing image data for pattern recognition. Based on the test results, the system demonstrates that the developed CNN model is capable of recognizing BISINDO finger spelling gestures with an accuracy of 97.5%. This indicates that the BISINDO finger spelling gesture recognition system performs well in pattern recognition. The implementation of the system for real-time prediction via a web interface using Flask also enhances its accessibility. However, there is still room for improvement, particularly in recognizing one of the 26 letters that has not been predicted accurately. For further development, it is recommended to consider collecting a larger dataset and incorporating more complex gesture variations to improve recognition accuracy.
Atrophy-related corticospinal changes in advanced Parkinson's disease are associated with the genetic etiology of the disease

Published: November 2024

Background

Compensatory mechanisms in Parkinson's disease (PD) are thought to explain the temporal delay between the beginning of the neurodegenerative process and the appearance of clinical signs. The enhanced structural integrity of the corticospinal tract was previously suggested as one of these mechanisms.

Objective

To understand the relations between corticospinal tract integrity and the anatomical, clinical, electrophysiological, and genetic PD characteristics.

Methods

We analyzed diffusion tensor imaging (DTI) fractional anisotropy (FA) data from 40 genotyped patients with PD (18 without known genetic cause, 11 with LRRK2-PD and 11 with GBA-PD) who were candidates for subthalamic deep brain stimulation (STN-DBS) and from 25 healthy, age-matched, controls.

Results

PD is associated with higher corticospinal FA values (p < 0.001) that are negatively correlated with the disease duration (p = 0.032), confirming previous results. Higher FA values are negatively correlated with cerebral grey matter volumes (p < 0.001) but not with the motor or cognitive PD characteristics, or with the subthalamic beta-oscillatory activity measured intra-operatively. Increased corticospinal FA values are strongly affected by the genetic etiology of PD, with higher values in the monogenic forms of the disease (p < 0.001). The compensatory index, calculated by dividing the corticostriatal FA value by the cerebral grey matter volume, is highest in GBA-PD (p < 0.001) at the time of evaluation for STN-DBS.

Conclusions

The genetic etiology of PD strongly shapes corticospinal tract changes along with disease-duration and cerebral grey matter atrophy. The changes may serve as compensatory mechanism.
