Published: December 2024

This study aims to develop lightweight and comfortable wearable devices using surface-relief grating, which can be designed to meet different diffraction conditions. However, extensive calculations must be performed to obtain the impact of the variation in the structural dimensions. The finite element method is used to solve the diffractive efficiency and then replaced by trained artificial neural networks with a single hidden layer containing 25 neurons. By using raw data with geometric parameters as the features, the performance of the network is investigated with different numbers of raw data; in addition, the regression analysis shows a high R-value of approximately 0.999. The predicted results are compared with those calculated from the simulation. The diffraction efficiency tendencies vary with the different geometric parameters, which show a high level of agreement between the predicted and calculated data; this confirms that the proposed method supports and reduces the burden of extensive calculations.

Published: December 2024

The gradual depletion of fossil fuels underscores the pressing need for technological advancements in renewable energy. These technologies are essential to address the inefficiencies in power generation from heliostat fields. This paper proposes an innovative heliostat field layout model aimed at significantly enhancing the efficiency of photovoltaic power generation. By carefully optimizing the positioning, height, and size of the heliostats, the model results in a substantial increase in annual heat output. Additionally, an improved Dung Beetle optimization algorithm (RCDBO) is introduced, which integrates random walk and cross strategy to enhance solving efficiency and accuracy while effectively avoiding premature convergence. Simulations demonstrate that the proposed algorithm achieves a 3% increase in efficiency compared to the traditional DBO algorithm, confirming the superiority of the RCDBO algorithm.

Published: December 2024

To address the problems of low accuracy and poor robustness in vehicle small object detection for autonomous driving tasks, this study aims to propose an improved vehicle small object detection algorithm model based on YOLOv5. Firstly, some convolutions in the backbone network are replaced with receptive field attention convolutions, and the weights of the convolution kernels are dynamically assigned based on the importance of image features to ensure the extraction of important features. Secondly, adding a channel attention mechanism to the backbone network enhances the attention to small target features. Finally, the Focal-EIoU loss function is introduced to increase the attention on high-quality samples in the regression stage of object detection boxes. When the model is applied to the small object test set of the KITTI dataset, the precision rate, recall rate and mean average precision are 88.5%, 82.8%, and 84.9%, respectively, and the frame processing rate reaches 87.83FPS.

MANAGERIAL COMPETENCE IN CHURCH STEWARDSHIP
Authors: Hutauruk Johnson Alvonco , Saputra Yudha Nata
Published: December 2024

The problem of mismanagement in church stewardship is caused by church leaders not being standardized in their managerial competencies which causes them to be unable to carry out their management functions, namely: planning, organizing, actuating, and controlling. This study addresses a notable gap in existing literature by providing a framework that links these competencies to the successful achievement of a church's vision, mission, and goals. The author proposes generic managerial competencies that must be standardized or possessed by the church leaders, such as General Ability, Willingness to do more, Creative Leadership, Goal & Objective Setting, Managerial, Emotional Quotient, Personality, human relations, work style, Loyalty, Work Potential. Finally, the research offers practical insights for church leaders enabling them to enhance their managerial skills and improve overall church governance and operational effectiveness.

Authors: Tuğal İhsan
Published: December 2024

This study assesses the effectiveness of five distinct Long Short-Term Memory (LSTM) architectures for forecasting wind speed in Muş, Turkey. The models include Vanilla LSTM, Stacked LSTM, Bidirectional LSTM, Attention LSTM, and Residual LSTM. The data, obtained from the Muş Meteorological Office, underwent preprocessing to handle missing values by averaging the same day and month values between 1969 and 2023. The dataset, containing 20,088 daily wind speed measurements, was split into training and test sets, with 80% allocated for training and 20% for testing. Each model was trained over 100 epochs with a batch size of 32, and performance was assessed using Mean Squared Error (MSE), Mean Absolute Error (MAE), and Mean Absolute Percentage Error (MAPE). The Vanilla LSTM model showed the lowest MSE and MAE values, indicating superior overall performance, while the Attention LSTM model achieved the lowest MAPE, demonstrating better percentage accuracy. These findings indicate that the Vanilla and Attention LSTM models are the most effective for wind speed forecasting, with the choice between them depending on the prioritization of total error versus percentage error.

Authors: Kara Emre , Sürmen Mustafa , Metin Türkan , Güngör Bekir Sami
Published: December 2024

Plant growth regulators (PGRs) are broadly used in turfgrass management. Gibberellic acid is also applied in many plants due to its positive effects on plant growth and development. However, some studies have indicated that these applications may have a negative effect on color. The study aimed to find out the effect of different doses of gibberellic acid applications on visual quality in different turfgrass species. Gibberellic acid was applied as control, 0.05 and 0.1 kg ha-1. Among the turfgrass species, twenty different cultivars of 4 different species were used as material in the experiment. Visual quality was assessed using a visual rating system. Color quality was examined using a spectrophotometer. In general, the use of gibberellic acid had negative effects on visual quality. Although there are studies showing that it increases resistance to stress conditions, visual quality is very important for turfgrasses. It was observed that grass species have different responses to gibberellic acid.

THREE DIFFERENT SPATIAL POSITIONS OF FAST MAGNETOSONIC WAVE COMPONENT TURNING POINTS
Authors: Girka I.O. , Trush O.V. , Tierens W.
Published: December 2024

Two different approaches to defining the cut-off in a magnetoactive plasmas are well-known. In one approach, a physicist searches the cut-off frequency for uniform plasma, that is for fixed values of plasma parameters, such as the plasma composition, plasma particle densities and external static magnetic field. This cut-off frequency separates
those frequencies, at which the electromagnetic wave is propagative, from those, at which it is evanescent one. In the other approach, a physicist searches the cut-off plasma particle density for the fixed frequency. The density is observed at the cut-off coordinate called in some text-books as “turning point” or “transition point”. This coordinate
separates the space, within which the wave is propagative, from the space, within which the wave is evanescent one. The conditions for determining the turning points depend not only on the values of plasma parameters themselves but on the plasma parameter gradients as well. These conditions are determined for the case of the electromagnetic
waves in ion cyclotron frequency range. Their deviation from the condition applied for the first approach is discussed.

Published: December 2024

The paper is devoted to determination of the effect of initial polarity of the high-voltage electrode connection of the plasma diode on the dynamic and energy characteristics of the discharge. It has been shown that it is possible to change the direction of charged particles beams, accelerated in the double layer, at the same levels of power and energy released in the discharge by changing the polarity of the high-voltage electrode connection. This is important for determining the sample location when it is irradiated with powerful pulse flows of charged particles that are formed and accelerated in the double layer of space charge, immediately in front of the sample surface.

HIGH-VOLTAGE PULSE GENERATOR ON THE BASE OF PLASMA TUBE WITH COLD CATHODE IN CROSSED FIELDS
Authors: Kuzmichev A.I.
Published: December 2024

A new scheme of the high-voltage pulse generator with a partial discharge of a capacitive energy storage on the base of the magnetically-controlled opening plasma switch tube is presented and investigated. The high-current magnetron discharge with the secondary-emission cold cathode in crossed-fields is used in the tube. The particularity of the generator scheme is the application of the anode voltage to the tube through a voltage divider to decrease the magnetic control power. The other special feature is the usage of an additional closing switch device (e.g., an ignitron) which is connected in series with the tube. The latter device is being triggered with some delay relatively the activation of the plasma switch tube. This technical approach creates conditions for a generation of the load current pulses with a minimal jitter due to ignition of a primary (pre-ionization) discharge in the tube before triggering
the closing device. Therefore, the start of the load current pulses is determined by triggering the closing device however the finish of the same thing is depended on the magnetron discharge switching-off through magnetic field turning-off in the tube. The new generator provided a stable generation of pulses at the amplitude of up to 200 A, duration in the range of 15…70 μs, the anode voltage of up to 20 kV and the average power of up to 100 kW. The pulse generator is designed for use in radio electronic and electro physical systems as well as in a plasma technology.

Published: December 2024

The influence of CrN and TiN coatings, deposited by cathodic arc evaporation, on deuterium permeation behavior in Ti-6Al-4V alloy was studied. Depth distribution profiles of deuterium were determined for both coated and uncoated Ti-6Al-4V samples following exposure to low-energy deuterium plasma to a fluence of 1·1023 D/m2 at room temperature. In the uncoated alloy, deuterium was found to redistribute throughout the bulk material, with permeation extending to the back side of the sample with respect to the irradiated surface. In contrast, deuterium permeation was limited to a negligible depth within the CrN and TiN coatings, emonstrating their excellent barrier performance.

DETERMINATION OF THE EFFECT OF DIFFERENT STERILIZATION PROTOCOLS FOR IN VITRO SHOOT TIP CULTURE IN SOME WILD PEAR (P. ELAEAGRIFOLIA) GENOTYPES
Authors: Pinar Hasan , Uzun Aydin
Published: December 2024

Wild pear(Pyrus elaeagrifolia) is one of the rootstocks used in pear cultivation. It is one of our most important genetic resources, especially because it is resistant to drought conditions and iron chlorosis. Besides its positive features, its use as a rootstock also has some disadvantages. In vitro propagation methods have gained importance in clonal propagation, especially due to the difficulties encountered in germination from seeds and problems in rooting with cuttings. With this method, mass production can be achieved in a short time. However, as in other species, contamination is the biggest obstacle in in vitro culture in pear. There is no valid protocol yet for surface sterilization processes for micropropagation of wild pear. New studies are needed for this purpose. The aim of this study was to determine the sterilization conditions suitable for the shoot tip technique to be used in in vitro propagation of some pear species. In the study, 4 different sterilization methods were applied to shoot tip explants of the wild pear genotype obtained from 6 different regions, and bacterial and fungal infection and plant development were examined in the explants. According to the results of present study, the contamination rate varied according to genotype and sterilization methods. The obtained results show that determining different protocols according to genotypes in in vitro micropropagation in important species such as wild pear (Ahlat) may affect the success of micropropagation.

This study examined the relationship between ChatGPT's usage frequency and perceived value among 386 international university students from selected universities in the Caraga and Northern Mindanao regions of the Philippines, specifically to the moderating role of disposable income. Utilizing a quantitative, cross-sectional survey design, the results showed a significant positive correlation between usage frequency and perceived value, supporting the hypothesis that more frequent use leads to greater perceived value. However, this relationship was found to be moderated by disposable income, with the correlation between usage frequency and perceived value being stronger among students with lower disposable incomes. These findings imply that while increased usage generally enhances perceived value, the effect weakens for higher-income students, possibly due to their access to alternative resources. The study underscores the need to consider disposable income when integrating AI tools into education to promote equitable access and maximize benefits for diverse student populations. Future research should investigate these dynamics longitudinally and across various academic disciplines.

Leadership plays a crucial role in creating a vision, pursuing a mission, and establishing organizational strategies. People express their leadership styles in various ways. A leader's effectiveness is defined by their performance in directing and influencing activities to achieve objectives (Dabke, 2016). This quantitative study investigated the relationship between leadership styles and skills awareness among student leaders at a state university. Utilizing a structured questionnaire, the study examined four definite leadership styles: Authoritative, Democratic, Facilitative, and Situational, alongside an extensive Skills Awareness Scale. A purposive sample of 43 student leaders, primarily under the age of 23, were included in the study. Of these, 61.9 % were female and 38.1 % were male. To examine the relationships between skill awareness and leadership methods, data were gathered and analyzed using ANOVA, multiple regression, chi-square tests, and descriptive statistics. The results of the study showed a moderate level of general skills awareness (mean = 3.341), suggesting a considerable amount of room for skill development. Although student leaders showed flexibility to many leadership styles, the authoritative approach stood out as uniquely significant. Students with more authoritative tendencies are likely to have better skills awareness, according to a statistically significant link between skills awareness and authoritative leadership (r = 0.318, p .040). No statistically significant differences in leadership styles were found by the one-way ANOVA test (p =.193), suggesting that student leaders take a flexible, nuanced approach rather than rigidly following one leadership styles. With the exception of the authoritative style, the Kruskal-Wallis test further demonstrated that leadership styles do not substantially alter levels of skill awareness. These results highlight the value of focused leadership development initiatives that support student leaders in developing their skills, especially in establishing authoritative leadership traits. The study advances knowledge of the intricate relationships between developing student leaders' leadership styles and skill awareness.

A debt agreement is a form of agreement commonly found in financial transactions, but often discusses issues related to its implementation and legal consequences. One form of problem that often arises is when a debt agreement is formulated in the form of a sale and purchase agreement, which does not reflect the substantial reality of the transaction that occurs. This can cause legal pollution, especially when the nominal value recorded in the agreement is much larger than the amount of debt actually received by the debtor. This case often shows a discrepancy between the purpose of the agreement and its actual implementation, which can ultimately harm one of the parties. This paper aims to analyze the legal consequences arising from a debt agreement formulated into a sale and purchase agreement, focusing on the aspects of justice and the legal validity of the agreement. In this study, it will be discussed how a sale and purchase agreement that does not reflect a real transaction can potentially reveal the principle of justice and harm the parties involved, as well as enforce the law caused by the discrepancy between the contents of the agreement and the reality that occurs. This research is expected to provide an understanding of the importance of transparency, fairness, and compliance with applicable legal principles in the principles of drafting and implementing debt agreements formulated into sales and purchase agreements.

Published: December 2024

O uso da inteligência artificial, aliado a técnicas de agricultura e zootecnia de precisão, está transformando o monitoramento e a gestão da agropecuária. O sensoriamento remoto, em particular, oferece uma solução inovadora para monitorar a variabilidade espaço-temporal em pastagens, fornecendo informações cruciais sobre diversos parâmetros biofísicos. Nesse contexto, o objetivo com este trabalho foi desenvolver modelos preditivos para a massa de forragem verde e seca, altura do dossel, densidade e concentração de matéria seca (%MS) e proteína bruta (%PB) de pastos de Urochloa decumbens (Stapf) R.D. Webster, utilizando aprendizado de máquinas e imagens multiespectrais obtidas por aeronave remotamente pilotada. O experimento foi conduzido na Universidade Federal de Viçosa, entre 2019 e 2020, com diferentes doses de nitrogênio aplicadas após cada corte, com o objetivo de promover variações nas características do capim. Foram avaliados o desempenho dos seguintes modelos: regressão linear simples (RLS), regressão linear múltipla (RLM), e randon forest regression (RFR). Para isso, dados multiespectrais foram extraídos de imagens aéreas e combinados à dados meteorológicos para alimentar os modelos preditivos. Os modelos foram avaliados por meio de validação cruzada “Leave-one-out”, utilizando métricas como coeficiente de determinação (R²), erro quadrático médio (RMSE) e erro absoluto médio (MAE). As melhores predições foram observadas para massa de forragem verde (R² = 0,77, RMSE = 3.281,29 kg ha-1, MAE = 2.361,80 kg ha-1) e seca (R² = 0,71, RMSE = 657,46 kg ha-1, MAE = 507,53 kg ha-1) com RLM, e altura do dossel com RLS (R² = 0,59, RMSE = 8,72 cm, MAE = 7,26 cm). As predições para % MS e % PB não apresentaram desempenho satisfatório para nenhum dos modelos avaliados. Conclui-se que a combinação de imagens aéreas multiespectrais com aprendizado de máquinas oferece uma ferramenta eficaz para prever variáveis como massa verde, massa seca e altura em pastos de capim-brachiaria, podendo contribuir significativamente para a gestão e o manejo das pastagens. Contudo, são necessárias mais pesquisas para otimizar os modelos desenvolvidos. Palavras-chave: sensoriamento remoto; multiespectrais; índices de vegetação aprendizado de máquina; imagens

DSA cria uma estrutura multinível piramidal constituída pelos
Coordenadores de Serviços Digitais, Comité Europeu dos Serviços Digitais
e Comissão, por ordem ascendente. É na base dessa estrutura que se
verificará uma maior proximidade com os Estados-Membros, competindo
aos mesmos designar o seu Coordenador dos Serviços Digitais e concretizar
as suas competências. Em Portugal a ANACOM foi designada como
Coordenador dos Serviços Digitais e a ERC e IGAC como autoridades
competentes, porém de modo manifestamente insuficiente. Neste estudo
iremos analisar a posição atual da ANACOM e os desafios que enfrentará na
sua atividade, considerando o contexto português, realizando um exercício
prospetivo sobre o futuro do Coordenador dos Serviços Digitais português.

Published: December 2024

Background: Globally, ovarian cancer accounted for 314,000 new cases and 207,000 deaths in 2020. In Uganda, 626 cases were documented over 25 years,
with an average incidence rate of 7.1 per 100,000 women. Epithelial ovarian carcinoma is the predominant subtype, and BCL-2, a 26-kDa anti-apoptotic
protein, has been associated with chemotherapy resistance. However, no study has assessed BCL-2 expression in epithelial ovarian cancer in Uganda.
Objective: This study aimed to determine the prevalence of BCL-2 protein expression in epithelial ovarian cancer and its association with age and
histopathological features in Uganda.
Methods: A retrospective cross-sectional study was conducted using randomly sampled archived tissue blocks from 113 patients diagnosed with epithelial
ovarian cancer. Samples underwent hematoxylin and eosin (H&E) and immunohistochemistry (IHC) staining to evaluate BCL-2 expression.
Results: The mean patient age was 55 years, with the largest proportion (36.3%) aged 50–59 years. BCL-2 expression was observed in 36.3% of cases. There
was no statistically significant association between BCL-2 expression and age (p = 0.396), histological subtype (p = 0.520), or tumor grade (p = 0.833).
High-grade serous carcinoma was the predominant histological subtype (46%), and well-differentiated carcinoma was the most common grade (53%).
Conclusion: BCL-2 expression was prevalent in epithelial ovarian cancer in Uganda but showed no significant association with age, histological grade,
or subtype. These findings underscored the need for further research to explore the prognostic and therapeutic implications of BCL-2 in ovarian cancer
management.

Optimizing Email Campaigns based on Pricing Variability
Authors:   Data Science, Glassdoor, California, USA, Pathe Anirudh Reddy
Published: December 2024

Email marketing is now a mainstay in most e-commerce customer engagement platforms especially considering dynamic pricing and personalized campaign
tactics. This paper explores how pricing-based cohort segmentation can best optimize email campaigns by identifying the appropriate consumer groups
sensitive to price changes so marketers can adjust the timing and content of their campaigns for maximum engagement and conversion. Three effective
strategies identified in this paper for cohorts and their related targeted email dispatch are leveraging user behavior data, real-time pricing adjustments,
and automation. Beyond that, the paper includes a review of challenges like synchronization issues, as well as data privacy issues, while incorporating
real-world case studies demonstrating the impact of cohort-based strategies on campaign performance. The future directions discussed look into the role
of AI and machine learning in generating higher accuracy levels for cohort segmentation and personalization, which shall serve as the road to refined datadriven email marketing strategies for e-commerce.

Authors: Voitovska V. I. , Zabolotna A. V. , Polishchuk T. V. , Korobko O. O.
Published: December 2024

Purpose. To obtain breeding genotypes of stevia tolerant to Alternaria alternata in vitro.
Methods. Shoots of different stevia varieties (‘Berehynia’, ‘Slavutych’, and ‘Halyna’) and lines (No. 3, No. 11, No. 14, and No. 16) were cultivated on modified Murashige and Skoog (MS) medium, supplemented with Alternaria alternata culture filtrate (CF) at concentrations ranging from 10 to 100%. ‘Berehynia’ variety served as the control. Cultivation was conducted at 24 ± 2 °C with a photoperiod of 16/8 hours. Shoot viability and biometric parameters were assessed on the 3rd and 7th days.
Results. A 100% CF concentration led to the death of shoots across all varieties and lines. At 10% concentration, the impact on viability was minimal, with most shoots remaining healthy and showing no changes in biometric parameters. Concentrations of 15 and 20% ensured high viability (72–95%) in all genotypes, with the best results observed for ‘Berehynia’ and ‘Slavutych’. At 25% concentration, viability decreased to 70–91%, and at 30%, to 68–90%. Concentrations from 35 to 45% reduced shoot viability to 20–63% and 20–47%, respectively, with ‘Halyna’ exhibiting the lowest values. Necrotic changes were observed at 25–45% concentrations, with the number of necrotic shoots increasing as concentration rose. Concentrations of 15–20% did not induce necrotic changes in ‘Berehynia’ and ‘Slavutych’, while in ‘Halyna’ and the lines, the number of necrotic shoots remained low.
Conclusions. The addition of CF to the medium at concentrations up to 20% did not critically affect shoot viability, shoot formation ability, or biometric parameters. Increasing concentrations above 20% led to reduced shoot viability and increased numbers of necrotic plants. The ‘Berehynia’ and ‘Slavutych’ varieties demonstrated the highest tolerance, whereas ‘Halyna’ proved the most sensitive, even compared to relatively tolerant stevia lines.

O desenvolvimento da indústria farmacêutica foi fortemente influenciado por mudanças nas técnicas e leis de estabilidade referente a medicamentos. Desde as primeiras regulamentações, que se concentravam principalmente na eficácia e segurança dos produtos, houve um progresso significativo na avaliação e controle da estabilidade. No início, as avaliações da estabilidade dos medicamentos eram mais simples e baseadas em testes físicos e químicos básicos. A incorporação de novas metodologias e diretrizes permitiram análises químicas mais detalhadas e precisas para IFA’s e produtos de degradação. O objetivo deste trabalho é analisar as mudanças nas práticas e legislações sobre a estabilidade de fármacos e medicamentos, avaliando seu impacto na segurança e qualidade dos produtos farmacêuticos. Trata-se de uma revisão narrativa onde foi realizada uma coleta de dados no ano de 2024, incluindo pesquisas que foram apresentadas nas bases de dados SciElo e PubMed. Os artigos e textos utilizados na revisão foram selecionados com base na sua data de publicação e relevância para o tema proposto. Este estudo é necessário para entender as mudanças nas práticas e legislações relacionadas à estabilidade de fármacos e medicamentos, pois essas mudanças têm um impacto direto na segurança, eficácia e qualidade dos produtos farmacêuticos. Assim, a análise das normas e práticas atuais é fundamental para garantir a conformidade e a inovação no desenvolvimento de medicamentos.
Reflexión Crítica sobre el Estudio de la Composición Genética de la Población Ecuatoriana
Authors: Romero Vanessa
Published: December 2024

La carta al editor sobre la composición genética de la población ecuatoriana ofrece importantes aportes al conocimiento de la diversidad genética del país1. El estudio utiliza 46 marcadores AIM-InDels, proporcionando una estimación valiosa del mestizaje en tres regiones clave: Amazonía, Costa y Sierra. Este enfoque permite visualizar cómo la ascendencia nativa americana, europea y africana varía según las diferentes zonas, lo que refleja parte de la compleja historia de Ecuador. Sin embargo, me gustaría señalar algunas limitaciones y áreas donde una mayor investigación podría enriquecer estos hallazgos.
