Authors: Sugiono Edi , Widodo Suwarno Tri
Published: February 2025

Human resources are a crucial asset for any organization, with employee performance playing a key role in achieving organizational objectives. Leadership, particularly transformational leadership, is one of the significant factors influencing employee performance as it enhances work motivation. Additionally, organizational commitment and employee engagement are essential elements that contribute to improving employee performance. Employee engagement serves as an intervening variable that mediates the relationship between transformational leadership and employee performance. The study employs a quantitative method with an associative approach to determine the relationship between these variables. Data collection was conducted using questionnaires, and the analysis was performed with SmartPLS software. The variables in this study include transformational leadership as the independent variable, employee engagement as the intervening variable, and employee performance as the dependent variable. The validity test results indicate that all items meet the required validity standards, while the reliability test results show that all variables have Cronbach's Alpha values above 0.6, indicating reliable measurements. Furthermore, transformational leadership also significantly enhances employee engagement, which, in turn, positively affects employee performance. Employee engagement is confirmed to be a mediating variable that strengthens the link between transformational leadership and employee performance. These findings align with the theory that transformational leaders can boost employee engagement by fostering an inspiring work environment, building trust, and promoting innovation.

Published: February 2025

Currently, there are many definitions of the investment attractiveness of a commercial organization; there is no single interpretation. This term consists of many factors – internal and external, financial and non-financial, indirect and direct. In addition to certain indicators, investment attractiveness is affected by which economic agent is interested in its assessment. This gives rise to subjectivity. In solving subjectivity, economists have developed several approaches – market, accounting and mixed. The mixed option, which involves creating an integral indicator based on the data obtained, is becoming increasingly popular. Despite the fact that this method seems universal, there are several problems that do not eliminate subjectivity in the analysis, do not increase the reliability of the assessment and require additional qualitative analysis, which can become overwhelming if it is not aimed at a specific area in which it is necessary to collect qualitative data to explain the obtained quantitative results. According to the author, the integral approach is decisive, but requires improvements. Instead of getting rid of subjectivity in the analysis, it is necessary to learn to control it. This can be achieved by inventing an integral formula with weights that can be selected in accordance with the needs of economic agents, taking into account the further explanation of the selection algorithm. Based on these weights, with three types of parameters – management efficiency parameters; parameters of the operating, investment and financial activities of the organization and parameters of the tax burden and systemic risks – it will be possible to consider the organization’s activities from several sides based on one universal formula and simplifies the selection of high-quality information necessary for interpreting the results obtained according to the model.

Currently, a very urgent problem is the exclusion or minimization of risks to ensure the survivability of unmanned aerial vehicles in the process of completing the task and achieving the intended result. The simple detection of failure without analyzing cause-and-effect relationships does not provide practical explanations and useful results for production and the user, and about 25% of the causes of incidents could not be established at all. Therefore, it is necessary to conduct risk studies and a deeper study of the failures of elements of unmanned aerial vehicles by analyzing the physico-chemical nature of the manifestation of failures, and this is not easy, since it requires the involvement of specialists of various profiles. In this regard, the work is developing a risk research methodology focusing on the physical nature of failures of elements of unmanned aerial vehicles.

One of the most pressing issues of anti-crisis management is the task of conflict management. The paper presents mathematical methods for structuring conflicting groups, and developed algorithms for rationalizing conflicting parties. A hierarchical model for managing the potential of conflicting parties has been constructed, and conflicts have been ranked taking into account their significance for the interacting parties. An effective modeling toolkit facilitating the resolution of controversial situations has been proposed. In this case, the use of mathematical methods can provide effective assistance in resolving controversial situations. This paper uses a composite hybrid of mathematical models to build solutions to controversial conflict situations using a specific example of a managerial nature. For example, a multi-criteria method has been used, followed by a paired comparison method, linear programming methods, and game theory models to create an objective platform for choosing an alternative for resolving a conflict. Methods for reducing tension in conflicting groups, and ways of making even unfavorable decisions in order to eliminate aggression in resolving conflicts have been proposed.

The fabrication of bioartificial tissue substitutes is a complex process that relies on the application of innovative biomaterials and manufacturing techniques enabling the generation of cell-laden scaffolds mimicking natural tissue interfaces. Among the many biomaterials, gelatin methacryloyl (GelMA) hydrogels have shown great potential for 3D bioprinting-based tissue engineering due to their high biocompatibility, biodegradability and tuneable mechanical properties. In this study, the potential use of hybrid hydrogels based on GelMA and a highly purified graphene-derivative (BioGraph) as biomaterials bioinks for extrusion-based 3D bioprinting was investigated. Formulations containing BioGraph concentrations of up to 0.1% (w/v) were well-suited for this technique, showing good extrudability with reduced clogging at the printing temperatures, effective photocrosslinking at the irradiances tested, high shape-fidelity and high resolution of the printed scaffold. In situ photocrosslinking tests revealed that BioGraph concentration decreased the speed of the photocrosslinking and the stiffness of the cured matrix. In vitro studies indicated that BioGraph content ≤ 0.1% (w/v) did not have an adverse impact on the viability and proliferation of rat adipose-derived mesenchymal stem cells (r-AMSCs). Similarly, acellular scaffolds implanted subcutaneously in rats showed a local macrophage-mediated inflammatory reaction and a collagen encapsulation process without any affection of surrounded host tissues. The addition of lower concentrations of BioGraph (0.025%, w/v) to the matrix resulted in enhanced macrophagic interactions and scaffold degradation in vivo, and r-AMSCs growth and proliferation in vitro. In conclusion, the GelMA-BioGraph hybrid hydrogels developed here demonstrate enhanced rheological and biological properties, tailored for extrusion-based 3D bioprinting with applications in the engineering of soft (neural, liver, etc.) or hard (bone) tissues.

Published: February 2025

To develop a hybrid scaffold that enhances bone regeneration and preventing infections by integrating polycaprolactone (PCL) scaffolds for mechanical support with bacterial cellulose (BC) membranes for psoralen (Pso) delivery,aiming to improve open bone defect treatment. PCL scaffolds were fabricated via 3D printing, and BC was extracted from fungi to prepare three types of scaffolds: PCL, BC-PCL, and BC-Pso-PCL. The scaffolds were characterized through scanning electron microscopy (SEM), contact angle measurement, and infrared spectroscopy. Biocompatibility was assessed by cytotoxicity (CCK-8) assay, cell migration assay, live/dead cell staining, and cell proliferation experiments. Antibacterial effects were tested under a simulated bacterial environment. Osteogenic performance was evaluated by alkaline phosphatase (ALP) activity, Alizarin red staining(ARS), and immunofluorescence after osteogenic induction. Quantitative PCR (qPCR) and Western blotting (WB) were performed to analyze bone regeneration and angiogenesis markers. Bone regeneration efficacy was assessed in vivo using a 5 mm critical-sized cranial bone defect model in rats(Figure 1A-C). Biocompatibility studies demonstrated that all three scaffolds showed good biocompatibility. Under Staphylococcus aureus exposure, BC-Pso-PCL effectively inhibited bacterial growth. The ALP and ARS results following osteogenic induction indicated that the BC-Pso-PCL group exhibited superior ALP activity and mineralized nodule formation compared to other groups. Subsequent immunofluorescence, qPCR and Western blot further confirmed the outstanding osteogenic performance of BC-Pso-PCL. In vivo experiments demonstrated that the BC-Pso-PCL scaffold achieved the highest level of new bone formation in rat cranial defects. The BC-Pso-PCL scaffold not only demonstrated superior biocompatibility in cytotoxicity, cell migration, live/dead staining, and proliferation assays, but also promoted bone regeneration and angiogenesis. The in vivo study further confirmed the superior bone formation achieved by BC-Pso-PCL. These findings highlight the potential of BC-Pso-PCL as an implantable scaffold for the treatment of open bone defects, providing a promising solution for future clinical applications.
Development of an Environmental Impact Methodology for Arctic Shipping: Exploring FMEA and STPA applications considering a Dynamic (varying) Baseline.
Authors: Gudmestad Ove Tobias , Stirpe Giacomo
Published: February 2025

Arctic shipping poses environmental risks due to the region's fragile ecosystems and rapid climate changes. Effective risk assessment tools are needed to ensure sustainable expansion and to carry out environmental impact assessments. This paper explores applications of Failure Modes and Effects Analysis (FMEA) and Systems-Theoretic Process Analysis (STPA) coupled with the consequences of a “Dynamic baseline approach” for Arctic shipping environmental impact assessment.
Shipping entails complex interactions between environmental, technical, human, and organizational factors. FMEA identifies failure modes and their effects through component-level analysis. STPA examines how unsafe control actions can emerge from interactions between system components. Combining these techniques with a dynamic (variable) baseline, accounting for inherent ongoing changing Arctic conditions, offers a robust methodology.
A qualitative case study shows that prioritizing hazards by risk, yields highest concerns, as increased greenhouse gas emissions, black carbon deposition on ice and snow, and response delays to accidents represent some of the most important identified threats to the environment. The use of FMEA and STPA are complementary, and differences are highlighted.
The methodology applied, should be representative for the qualitative risk analysis methodology, and while the findings are impacted by the perspectives of the authors, the process followed is intended to identify and rank risks in a consistent manner.
Mitigations measures must be in place to target these issues. Constant monitoring of the changing ecological and socioeconomic Arctic baselines supports the responses.
This methodology offers a starting point for systematically addressing environmental impact risks in the data-limited Arctic. Integrating failure modes and effect analysis, system theories and dynamic baselines, account for identification of the complex interactions, influencing environmental risks in this rapidly evolving region.
A Proposed Advanced Controller Applied to a Single-phase Power Factor Correction Converter in Electric Vehicle Chargers

Published: February 2025

This work proposes a novel approach for managing the output DC link voltage of a single-phase power factor correction (PFC) converter for electric vehicle (EV) charging without using a DC voltage sensor. The inputs and outputs of conventional boost PFC converters normally use several expensive sensors such as input voltage, input current, and output voltage. These sensors are employed to maintain system stability and control the quality of the power. A DC voltage sensorless control utilizing an estimator is used to lower the cost and hardware complexity of the power converter. The output DC link voltage is predicted using the available input voltage and current signals. For a high power factor, the controller follows the reference sine wave signal. Additionally, the converter exhibits extremely steady performance under transient fluctuations in load for a typical 1kW PFC converter. A novel Simplified Optimum Intelligent PID (SOI-PID) controller is designed for a 2.4kW, 400V output voltage, and 6A rated load, based on the second order transfer function of the system, both designs are analyzed, simulated, and compared for the same circuit parameters and loading conditions. The novel SOI-PID controller has shown advantageous performance in both transient and steady-state periods including lower rise and settling times, lower maximum overshoot, fast response to load variation, and lower stress on switching element which leads to better efficiency and lower fixed cost of the overall system.

The main objective of this research is to introduce a new type of control chart, the New Modified EWMA control chart, to detect changes in the process of the average value by studying both one-sided and two-sided control charts. The model studied in this research is the moving average process, or MA(q), with an exponential distribution of residuals. The explicit formula for the average run length of the modified EWMA control chart using the integral equation method to prove the average run lenis are presented. The results of the research found that the average run length obtained has high accuracy and is fast in finding the value when compared to the numerical integral equation method. In this research, several models, such as MA(1), MA(2), and MA(3) processes, were simulated at different parameter levels. In addition, it has been applied to real environmental data, including PM2.5 and PM10 data in Thailand. If the control limits for PM2.5 and PM10 are exceeded, it can be used to identify a potential environmental issue, enabling authorities to investigate the situation and take action before the air quality gets worse.

Survey measures of metacognitive monitoring are often false
Authors: Double Kit S.
Published: February 2025

Metacognitive monitoring is an extremely important ability that predicts a wide range of outcomes. However, do people have insight into their own metacognitive monitoring capacity? This study measured participants' perceived metacognitive monitoring abilities using a novel psychometrically validated questionnaire (Study 1) and then examined how well survey responses aligned with online measures of metacognitive monitoring (resolution, discrimination, sensitivity, efficiency) taken from confidence ratings participants made while performing a perceptual decision-making task and Raven’s Progressive Matrices (Study 2). We found a negative correlation between the questionnaire responses and many of the online measures of metacognitive monitoring – those who reported being better at metacognitive monitoring, in fact tended to be worse according to the online metacognitive ratings. This occurred because, in general, high self-perceptions of monitoring ability were, in fact, related to higher confidence and lower cognitive performance. These findings suggest that we may have inaccurate insights into our own metacognitive monitoring capacity and questionnaire-based measures of metacognitive abilities may be problematic as they may represent unrealistic self-perceptions.

O estudo investiga os impactos do assédio moral e sexual na saúde mental dos trabalhadores, analisando suas consequências psicológicas, sociais e organizacionais. A pesquisa, baseada em uma revisão sistemática da literatura entre 2015 e 2024, revela que o assédio no trabalho está diretamente ligado a transtornos como depressão, ansiedade, estresse crônico e burnout. Vítimas frequentemente enfrentam baixa autoestima, insônia, dificuldades de concentração e absenteísmo elevado, comprometendo sua produtividade e bem-estar. No âmbito organizacional, empresas com casos recorrentes de assédio sofrem com alta rotatividade, clima corporativo deteriorado e perda de eficiência. A ausência de políticas preventivas e canais eficazes de denúncia favorece a perpetuação dessas práticas, tornando o ambiente inseguro. Setores altamente competitivos e hierárquicos apresentam maior incidência do problema, reforçando a necessidade de medidas estruturadas para enfrentá-lo. Diante desse cenário, a adoção de estratégias como treinamentos, suporte psicológico, políticas rigorosas e responsabilização dos agressores é essencial para mitigar os impactos negativos. A erradicação do assédio deve ser encarada como um compromisso ético e social, além de uma obrigação legal, garantindo um ambiente de trabalho mais seguro e saudável.

Published: February 2025

Este estudio analiza las variaciones en el Producto Interno Bruto (PIB) y los indicadores del sistema financiero desde 2012 hasta 2022 para comprender la dinámica económica del Departamento de Pando, Bolivia, con especial atención en Cobija, su capital. Se observa una marcada influencia de factores externos como la fluctuación del real brasileño y los precios internacionales de la castaña. Además, se examinan las implicaciones de las políticas económicas nacionales que buscan controlar los ciclos económicos y mitigar la pobreza y la desigualdad. La investigación revela que la economía de Pando es altamente dependiente de la actividad fronteriza con Brasil, lo que la hace vulnerable a crisis externas, incluyendo la caída del real brasileño y la crisis sanitaria del COVID-19. Este último evento en particular exacerbó la recesión económica preexistente, afectando severamente el comercio y los servicios en la región. A nivel financiero, se observó una correlación positiva entre el crecimiento de los depósitos del público y la evolución del PIB, sugiriendo que el sector financiero desempeña un papel crucial en el desarrollo económico de la región. Sin embargo, también se notaron periodos de desaceleración en los créditos y los depósitos, coincidiendo con las crisis económicas y sanitarias mencionadas. Por lo tanto el es estudio concluye que la economía de Pando requiere de una diversificación más amplia para mejorar su resiliencia frente a shocks externos y promover un desarrollo económico más sostenible y estable.

Authors: Choque Ronald Williams Bautista , Romero Flora Magdaline Benitez
Published: February 2025

El presente artigo pretende analizar las propiedades fisicoquímica de la pulpa de asaí (Euterpe precatoria) y estudio de la aplicación de tratamientos térmicos en el fruto para su conservación poscosecha. Utilizando frutos originarios del municipio de Santa Rosa, se compararon técnicas de almacenamiento en condiciones de refrigeración y congelación, con y sin un tratamiento térmico previo de escaldado. Las evaluaciones fisicoquímicas realizadas revelaron que los tratamientos térmicos y las condiciones de almacenamiento adecuadas son esenciales para mantener la calidad de la pulpa de asaí. Los resultados demostraron que las variaciones en los tratamientos afectan significativamente la densidad, el pH y los sólidos solubles de la pulpa, con los prototipos desarrollados mostrando propiedades comparables o superiores a las de una muestra comercial. Además, los resultados confirmaron que los métodos estandarizados de conservación pueden efectivamente extender la vida útil del asaí y preservar sus propiedades nutricionales y organolépticas.

Published: February 2025

El presente artículo analiza el procesamiento de Euterpre precatoria (Asai) en la comunidad de Trinchera, enfatizando la variabilidad en el tamaño y peso de los frutos, que afecta directamente la eficiencia de su procesamiento. Se identificó que la variabilidad puede requerir ajustes en la maquinaria, resaltando la importancia de estandarizar procedimientos para maximizar la extracción de pulpa y minimizar el desperdicio. El estudio revela que aproximadamente el 25% de los frutos presentan variaciones significativas que impactan en las técnicas de procesamiento. Además, se descubrió que un 15% de la materia prima contiene impurezas, lo que subraya la necesidad de mejorar las prácticas de recolección y los procesos iniciales para asegurar que los frutos cumplan con estándares de calidad y seguridad alimentaria. La densidad a granel de los frutos, que influye significativamente en la logística de almacenamiento y transporte, se mide en 650 kg/m³, lo cual es crucial para planificar el espacio de almacenamiento y optimizar los costos de transporte. Asimismo, se observó que la relación pulpa/fruto es aproximadamente del 10%, indicando una necesidad urgente de mejorar las técnicas de extracción de pulpa para aumentar el rendimiento, lo cual podría incrementar la eficiencia de producción en un 30%. Por lo tanto, es necesario la capacitación continua y el apoyo técnico para fortalecer la eficiencia y competitividad de los emprendimientos locales. La implementación de mejoras propuestas podría ayudar a asegurar la viabilidad económica y la sostenibilidad ambiental de la comunidad, alineando las operaciones con los objetivos de desarrollo sostenible y mejorando la gestión de recursos naturales.
