Published: November 2024

Numerous bacterial species can both suppress plant pathogens and promote plant growth. By combining these bacteria with stabilizing substances, we can develop biological products with an extended shelf life, contributing to sustainable agriculture. Bacillus subtilis is one such bacterial species, possessing traits that enhance plant growth and offer effective protection, making it suitable for various applications. In this study, we successfully incorporated B. subtilis into hybrid materials composed of poly(3-hydroxybutyrate) (PHB) fibers coated with chitosan film. The polymer carrier not only supports the normal growth of the bioagent but also preserves its viability during long-term storage. For that reason, the impact of chitosan molecular weight on the dynamic viscosity of the solutions used for film formation, as well as the resulting film’s morphology, mechanical properties, and quantity of incorporated B. subtilis, along with their growth dynamics was investigated. SEM was used to examine the morphology of B. subtilis, electrospun PHB, and PHB mats coated with chitosan/B. subtilis. The results from mechanical tests demonstrate that chitosan film formation enhanced the tensile strength of the tested materials. Microbiological tests confirmed that the bacteria incorporated into the hybrid materials grow normally. The conducted viability tests demonstrate that the bacteria incorporated within the electrospun materials remained viable both after incorporation and following 90 days of storage. Moreover, the prepared biohybrid materials effectively inhibited the growth of the plant pathogenic strain Alternaria. Thus, the study provides more efficient and sustainable agricultural solutions by reducing reliance on synthetic materials and enhancing environmental compatibility through the development of advanced biomaterials capable of delivering active biocontrol agents.

Authors: Wang Qi , Mutailipu Meiheriayi , Xiong Qiang , Jing Xuehui , Yang Yande
Published: November 2024

The precision of photovoltaic (PV) output forecasting results is crucial to the reliability of the intelligent distribution network and multi-energy supplementary system. This work aims to address problems of insufficient research related to the short-term prediction of small-sample PV power generation and the low prediction accuracy in the previous research. A hybrid prediction model based on grey relation analysis (GRA) combined with the sparrow search algorithm (SSA) and the grey neural network model (GNNM) is proposed. In this paper, GRA is utilized to reduce the dimension of meteorological features of the samples. Then, the GNNM is used to perform regression analysis on the input features after reducing the dimension of meteorological features of the samples, and the parameters of the GNNM are optimized via SSA. A limited dataset was used to compare several models in different seasons and weather conditions. The prediction results agree well with the data from the PV power plant in Xinjiang, indicating that the GRA-SSA-GNNM model developed in this work effectively achieves a high precision estimation in short-term PV power generation output prediction and has a promising application in this field.
Assessing the Parenting Stress Index-Short Form (PSI-SF) for Latinx Parents of Children with Intellectual and Developmental Disabilities Within Exploratory Structural Equation Modeling and Structural Equation Modeling-Based Generalizability Theory Frameworks
Authors: Hong Hyeri , Rios Kristina
Published: November 2024

Although the Parenting Stress Index-Short Form (PSI-SF) is widely applicable, there has been a dearth of research on the psychometric properties and item wording effects associated with the cultural sensitivity of the instrument. This study investigated the psychometric properties, the factor structure, and the negative and positive item wording effects of PSI-SF for 96 Latinx parents of children with intellectual and developmental disabilities in the United States within exploratory structural equation modeling, and structural equation modeling-based generalizability theory frameworks. This study produces the following noteworthy findings. First, the ESEM bifactor model with negatively and positively phrased items best captured the theoretical frameworks underlying the structure of the PSI-SF. Second, adding method factors enhanced the model fits of all the factor models. Third, this study discovered several items with great proportions of method factors. This study recommended that the items with high proportions of method factors, which may likely be culturally insensitive to Latinx parents, be examined further and refined. With the use of accurately assessed PSI-SF scores, practitioners will be better able to support and empower Latinx parents of children with IDD and better meet their needs through the FIRME program, a parent advocacy initiative.
Systemic Coagulation Derangement as an Early Sign of Oxygenator Failure in Veno-Venous Extracorporeal Membrane Oxygenation (VV ECMO) Without Anticoagulation
Authors: Szułdrzyński Konstanty , Jankowski Miłosz , Fleming Magdalena
Published: November 2024

Background and Clinical Significance: Veno-venous extracorporeal membrane oxygenation (VV ECMO) has become a widely accepted supportive treatment for severe acute respiratory distress syndrome (ARDS) in intensive care units (ICUs). Although it has gained popularity, some of its aspects, including optimal anticoagulation management and the best means of monitoring hemostasis, remain unresolved. Thrombosis and bleeding are still important complications of ECMO. Case Presentation: A 44-year-old male patient, with no underlying conditions, was diagnosed with severe acute respiratory distress syndrome (ARDS) due to AH1N1 influenza. He presented severe hypoxemia despite the use of mechanical ventilation, neuromuscular blocking agent infusion and prone position. VV ECMO was used, and coagulation was stopped on ECLS day 6 due to severe pulmonary hemorrhage. The systemic hemostatic disorders found in this patient were difficult to differentiate from disseminated intravascular coagulation (DIC) or sepsis-induced coagulopathy (SIC), improved transiently after circuit exchange, and resolved only after discontinuation of ECMO. The patient was discharged fully conscious and cooperative, with no apparent neurological deficit. Conclusions: Systemic hemostatic abnormalities may precede oxygenator failure and mimic DIC or SIC. Timely oxygenator exchange may therefore be considered. However, it is a high-risk procedure, especially in fully ECLS-dependent patients.
3D Point Cloud Fusion Method Based on EMD Auto-Evolution and Local Parametric Network
Authors: Chen Wen , Chen Hao , Yang Shuting
Published: November 2024

Although the development of high-resolution remote sensing satellite technology has made it possible to reconstruct the 3D structure of object-level features using satellite imagery, the results from a single reconstruction are often insufficient to comprehensively describe the 3D structure of the target. Therefore, developing an effective 3D point cloud fusion method can fully utilize information from multiple observations to improve the accuracy of 3D reconstruction. To this end, this paper addresses the problems of shape distortion and sparse point cloud density in existing 3D point cloud fusion methods by proposing a 3D point cloud fusion method based on Earth mover’s distance (EMD) auto-evolution and local parameterization network. Our method is divided into two stages. In the first stage, EMD is introduced as a key metric for evaluating the fusion results, and a point cloud fusion method based on EMD auto-evolution is constructed. The method uses an alternating iterative technique to sequentially update the variables and produce an initial fusion result. The second stage focuses on point cloud optimization by constructing a local parameterization network for the point cloud, mapping the upsampled point cloud in the 2D parameter domain back to the 3D space to complete the optimization. Through these two steps, the method achieves the fusion of two sets of non-uniform point cloud data obtained from satellite stereo images into a single, denser 3D point cloud that more closely resembles the true target shape. Experimental results demonstrate that our fusion method outperforms other classical comparison algorithms for targets such as buildings, planes, and ships, and achieves a fused RMSE of approximately 2 m and an EMD accuracy better than 0.5.
Defect Trends in Fire Alarm Systems: A Basis for Risk-Based Inspection (RBI) Approaches
Authors: Veit Stefan , Steiner Frantisek
Published: November 2024

This article presents a comprehensive statistical evaluation of defect frequency in fire alarm systems under real operating conditions, focusing on risk-based factors. The aim is not to introduce a complete RBI approach but rather to assess defect trends that can inform future RBI-based inspection strategies. The study categorizes and evaluates defects by frequency, particularly examining components such as cable and wire systems, acoustic signal devices, and the impact of detector contamination. These findings establish a foundation for developing tailored risk-based inspection and predictive maintenance strategies. A three-stage explanatory research design was employed, analyzing 4629 inspection reports with findings verified through expert surveys and cross-sample analysis. Results indicate that certain components, including acoustic devices and detectors, exhibit a significant increase in defects after 10 years, especially under challenging environmental conditions. Additionally, while ring bus technology supports less frequent functional testing, cable and wire systems require heightened attention in the early operational years. The study also identifies statistically significant trends and their potential for application to a broader system population, supporting enhanced RBI-based maintenance practices. These insights contribute to refining current maintenance approaches and offer practical recommendations for optimizing inspection routines based on risk factors. The article does not propose a system overhaul but lays essential groundwork for further research and improvement in fire alarm system reliability through targeted, risk-informed practices.
Early Strength and Microscopic Mechanisms of Alkali-Metal Hydroxide-Activated Tungsten Tailings
Authors: Li Shanmei , Wang Lei , Liu Zhikui , Shou Kai
Published: November 2024

The excellent mechanical properties of alkaline-activated tailings are essential for their increased use in building materials. While numerous studies have been conducted on activated tailings, the strength of alkaline-activated tungsten slag has not been extensively explored due to the low reactivity of silicon and aluminum in these tailings. This research delves into the early unconfined compressive strength of tungsten tailings activated by two alkali solutions (NaOH and KOH) at three different alkali concentrations (mass ratio of alkali to tungsten tailings), cured at 80 °C over periods of one day, three days, and seven days. The study finds significant improvements in the stability of tungsten tailings when forming (C, N)-A-S-H or (C, K)-A-S-H gels with both alkalis. Scanning Electron Microscope (SEM) results show that the morphology of the (C, N)-A-S-H gels transitions from membranous to flocculated and then to a three-dimensional network as the NaOH content and curing time increase. Conversely, the (C, K)-A-S-H gels primarily exhibit thin-film morphology with some three-dimensional network structures. The presence of flocculation and three-dimensional mesh in the gels fosters the formation of a robust skeletal structure, enhancing the strength of the samples. Furthermore, specimens treated with NaOH solution exhibit a higher gel content compared to those treated with KOH solution. These factors contribute to the superior efficacy of sodium hydroxide in enhancing the strength of tungsten tailings compared to potassium hydroxide. X-ray Diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FTIR) results identify the formation of new phases such as pirssonite, buetschliite, potassium bicarbonate, and potassium carbonate. The first new phase results from the carbonization of excess NaOH solution, while the latter phases arise from the carbonization of excess KOH solution. These carbonization processes negatively impact the strength of the materials.
Modular Modeling of a Half-Vehicle System Using Generalized Receptance Coupling and Frequency-Based Substructuring (GRCFBS)
Authors: Hamedi Behzad , Taheri Saied
Published: November 2024

This paper presents an advanced modular modeling approach for vertical vibration analysis of dynamic systems using the Generalized Receptance Coupling and Frequency-Based Substructuring (GRCFBS) method. The focus is on a four-DoF half-vehicle model comprising three key subsystems: front suspension, rear suspension, and the vehicle’s trimmed body. The proposed technique is designed to predict dynamic responses in reconfigurable systems across various applications, including automotive, robotics, mechanical machinery, and aerospace structures. By coupling the receptance matrices (FRFs) of individual vehicle modules, the overall system receptance matrix is efficiently derived in a disassembled configuration. Two generalized coupling methods, originally developed by Jetmundsen and D.D. Klerk, are employed to determine the complete vehicle’s receptance matrix from its subsystems. Validation is achieved by comparing the results with established methods, such as direct solution and modal analysis, demonstrating high accuracy and reliability for complex dynamic systems. This modular approach allows for the creation of reduced-order models focused on key measurement points without the need for detailed system representation. The method offers significant advantages in early-stage vehicle development, providing critical insights into system vibration behavior.
RBCKF-Based Vehicle State Estimation by Adaptive Weighted Fusion Strategy Considering Composite-State Tire Model
Authors: Chen Xi , Cheng Xinlong
Published: November 2024

The acquisition of vehicle driving status information is a key function of vehicle dynamics systems, and research on high-precision and high-reliability estimation of key vehicle states has significant value. To improve the state observation effect, a vehicle sideslip angle estimation method adopting a robust bias compensation Kalman filter and adaptive weight fusion strategy is proposed. On the basis of the extended Kalman filter algorithm, and with the goals of estimation exactitude and robustness, considering the potential signal deviation, a vehicle state robust deviation compensation Kalman filter estimation algorithm considering bias compensation and residual covariance matrix weighting is proposed. Meanwhile, considering the adaptive and dynamic adjustment capabilities of the observation system in complex state-change scenarios, an estimation strategy based on adaptive weight fusion and a model-based estimator is proposed. The results confirm that the robust bias compensation Kalman filter can ensure estimation exactitude and robustness when the vehicle state fluctuates greatly, and the proposed fusion strategy can ensure that the vehicle maintains optimal estimation performance during operating condition switching.
e-Fuel: An EV-Friendly Urgent Electrical Charge-Sharing Model with Preference-Based Off-Grid Services

Published: November 2024

Electric-powered vehicles (EVs) allow for an environmentally friendly and economic alternative to fuel-running ones. However, such an alternative is expected to impose further usage hikes and periods of instability on cities’ power systems. From their perspective, cities need to scale their infrastructure grids to allow for adequate power resources to feed such new power-hungry consumers. Indeed, for such a green alternative to proceed, our power grids need to be ready to cope with any unexpected hikes in the power consumption rates without compromising the stability of the services provided to our homes and workplaces. Operators’ steps in this path are still modest, and the coverage of EV charging stations is still insufficient as they are trying to avoid any further costs for upgrading their infrastructures. The lack of price consideration for the charging services offered at charging stations may result in EV drivers paying higher costs compared to traditional fuel vehicles to charge their EVs’ batteries, hindering the economic incentive of owning such sorts of vehicles. Hence, it may take a while for sufficient coverage to exist. Although for drivers the adoption of EVs represents a city-friendly alternative with affordable expenses, it usually comes with range anxiety and battery charging concerns. In this work, we are presenting e-Fuel, a charge-sharing model that allows for preference-based mobile EV charging services. In e-Fuel, we are proposing a stable weight-based vehicle-to-vehicle matching algorithm, through which drivers of EVs will be capable of requesting instant mobile charge-sharing service for their EVs. In addition to being mobile, such charging services are customized, as they are chosen based on the drivers’ preferences of price-per-unit, charging speed, and time of delivery. The developed e-Fuel matching algorithm has been tested in various environments and settings. Compared to the benchmark price-based matching algorithm, the resulting matching decisions of e-Fuel come with balanced matching attributes that mostly allow for 6- to 7-fold shorter service delivery times for a minimal increase in service charges that vary between 9% and 65%.

A rosácea é uma doença dermatológica crônica com manifestações cutâneas e oculares que se caracteriza pela vermelhidão no centro da face. Quando sem tratamento adequado e/ou em formas evoluídas da doença podem apresentar pápulas e pústulas. Em casos mais graves, pode-se observar sinais de hipertrofia tecidual denominadas alterações fimatoses, que são comuns no nariz; onde recebe o nome de rinofima. Devido ao agravo dos sintomas, faz- se necessário o tratamento individualizado, bem como a rotina de cuidados pessoal do paciente. O uso de alguns princípios ativos, sejam eles em cosméticos ou nutracêuticos diminuem/retardam a evolução desses sintomas. Bem como a evolução e o agravo da doença. Cada princípio ativo atende uma necessidade ou subtipo da doença; para trabalhar a personalização do tratamento preza-se pela consulta com o médico dermatologista, que deverá diagnosticar o subtipo da rosácea do paciente e as queixas do mesmo quanto aos sintomas, visando a indicação dos princípios ativos, de acordo com o tratamento presonalizado do paciente. Essa personalização se baseia na escolha e concentração dos ativos e a forma farmacêutica que apresenta um resultado mais eficaz.

A Hiperplasia Prostática Benigna (HPB) é uma condição extremamente prevalente em homens, que geralmente cursa com sintomas incomodativos do trato urinário inferior. Tratamentos cirúrgicos minimamente invasivos, como o Urolift® e o HoLEP, surgiram como intervenções eficazes e seguras, cada um com suas vantagens e limitações. A partir disso, objetivou-se comparar dados objetivos intra e pós-operatórios entre estas duas técnicas, a fim de analisar se há superioridade de alguma. Para tanto, o estudo adotou como metodologia uma coorte retrospectiva. Os pacientes foram divididos em dois grupos, cada um submetido a uma das técnicas em um hospital privado de Curitiba, Paraná. Os dados coletados foram: idade, volume prostático, tempo cirúrgico, internamento, sonda vesical, complicações intra e pós-operatórias e ejaculação retrógrada. O programa IBM SPSS Statistics v.28.0 foi utilizado para análise, que envolveu descrição das variáveis, Teste T de Student ou Mann-Whitney para variáveis quantitativas contínuas e teste qui-quadrado ou exato de Fisher para variáveis categóricas. Os resultados revelaram diferenças estatisticamente significativas entre os grupos no que diz respeito ao volume prostático (p = 0,004) e tempo cirúrgico (p < 0,001). Não foram observadas diferenças significativas em relação à idade (p = 0,130), complicações intraoperatórias (p = 1,000), tempo de internamento (p = 0,086), tempo de sonda vesical (p = 0,100), ocorrência de sangramento pós-operatório (p = 0,489) e ocorrência de ejaculação retrógrada (p = 0,642). Concluímos que a técnica Urolift® cursou com menor tempo cirúrgico e abordou próstatas menores. Contudo, ambos os procedimentos demonstraram-se igualmente seguros.

A fibrilação atrial é a arritmia mais comum na população geriátrica e está diretamente relacionada com eventos tromboembólicos. Por isso, a terapia de anticoagulação oral já está bem estabelecida, porém é necessário considerar a relação risco / benefício dos anticoagulantes no manejo de idosos com fibrilação atrial, entre elas destacam-se a fragilidade, a disfunção renal, a disfunção cognitiva e o risco de quedas. Aqueles indivíduos com contraindicação a anticoagulação oral, podem se beneficiar da oclusão do apêndice atrial esquerdo. Este procedimento é responsável pela obliteração desta estrutura como terapêutica alternativa para prevenção de acidente vascular encefálico, uma vez que 90% dos trombos se originam nessa localização anatômica.  Segundo estudos randomizados, a oclusão do apêndice atrial esquerdo apresentou menores taxas de mortalidade cardiovascular e similaridade quanto à ocorrência de acidente vascular encefálico, quando comparado com a varfarina. Portanto, é uma alternativa segura e eficaz na prevenção de eventos tromboembólicos em pacientes com critérios de elegibilidade para o procedimento.

Published: November 2024

O artigo discute os métodos mais seguros para diagnosticar hipersensibilidade à amoxicilina em crianças, uma condição que pode levar ao uso de antibióticos de segunda linha com efeitos adversos no tratamento. O objetivo é avaliar o método mais seguro e eficaz de diagnóstico: o teste de provocação oral (TPO) ou o teste cutâneo. A metodologia consistiu em uma revisão de literatura baseada em estudos obtidos na plataforma PubMed entre 2020 e 2023. Os resultados indicam que o TPO é o método mais seguro e eficaz para identificar hipersensibilidade à amoxicilina em crianças, sendo possível dispensar o teste cutâneo em casos leves. No entanto, em situações de reações graves, como anafilaxia, o teste cutâneo é recomendado. A revisão conclui que o teste de provocação oral, sem a necessidade prévia de testes cutâneos, é o método mais indicado para o diagnóstico de hipersensibilidade à amoxicilina, exceto em casos graves, onde o teste cutâneo é recomendado como abordagem diagnóstica preliminar.

This study aimed to investigate the changes in the self-directedness of freshmen in the department of science education through a self-directed learning participation program. It also aimed to investigate the meaning they gained from this program. In this, study 24 freshmen participated in. The results are as follows: First, the results of the self-directedness test showed statistically significant changes at the p < .01 level. The sub-items of attachment to learning, openness to challenges, self-confidence as a learner, curiosity about learning, acceptance of responsibility for learning, and self-understanding all showed statistically significant changes at the p < .05 level. Second, when examining the preparatory process for freshmen, efforts were made to recognize the class objectives and convey them to students to clarify, but no efforts were made to induce motivation to learn when approaching learning problems. And there was a lack of consideration of what should be taken into account for effective learning in the teaching-learning process. In addition, there was a lack of understanding of the reasons and methods for organizing and evaluating classes. Third, freshmen had positive thoughts about the self-directed class participation program, and they thought that it should be actively utilized in teacher training courses, and that allowing secondary school students to prepare and apply classes on their own would have a positive effect on learning. In conclusion, it is necessary to develop and apply such self-directed class participation programs for future science teachers, and should be applied in secondary school as well.

Published: November 2024

The bronze artifacts of Mandolin-shaped Bronze Daggers Culture in Hoseo(湖西) region show a continuous distribution area from the Geumgang to the Mangyeonggang. One or two bronze artifacts are usually excavated from the dwelling site and tombs. This difference in excavated feature is reflected the style or space-time. For example, the stone coffin tomb with ditch or simple pit tombs are natives in the early period, and the wooden coffin tombs with stone-filled are known as foreigns in the late period.
There are many weapons such as bronze daggers and bronze spearheads in bronze artifacts. The bronze daggers have various style or type that connect Liaodong, Liaoshi, and Northwest region. The bronze spearheads is identified as a universal short type and a be naturalized long type. In addition, the bronze axes of the northeastern style and the bronze mirror of the northwest style are confirmed.
The Mandolin-shaped Bronze Daggers Culture in the Hoseo region underwent four phase of change. During the 1st phase, only narrow bronze daggers are identified alone, and an interaction (distribution) relationship that connects to ‘Liaodong-Northwest-Southwest’ is identified. In the 2nd and 3rd phase, it is replaced by a wide bronze daggers, and bronze spearheads and bronze axes are added. The interaction relationship between ‘Northwest-Northeast’ increases, and bronze weapons is also used as a ritual. During the 4th phase, transitional models such as the straight-edged bronze daggers and dagger pommel fitting, bronze mirror, and half-moon-shaped jade appear. This shows that the interaction relationship between ‘Liaodong-Northwest-(Central)-Southwest-’ was further strengthened during the settlement of the Jeongjiawazhi assemblage.
Excavated Context on the Handaxes of Paleolithic in Miho River Basin: Focusing on the Sites at Cheongju City
Authors:   The hoseo Archaeological Society, Lee Jungchul
Published: November 2024

The excavated contexts on the handaxes of paleolithic from Cheongju City in the Miho River basin were identified through a geoarchaeological approach.
The handaxes are mostly concentrated on the slopes and slope ends of hilly mountains within 50m above sea level adjacent to floodplains. They are also found on some floodplain flats and in the mountains. These features are subject to slope and fluvial deposits. At the sites, fluvial deposits formed at MIS 3 and MIS 5. The slope deposits were deposited repeatedly, some rapidly. The slopes are related with MIS 2~MIS 4, and the ends of slope with MIS 2~MIS 5. Some Paleolithic artifacts are recovered from fluvial deposits, but most are found within the slope deposits.
The handaxes are excavated from five layers. First. The dark brown clay layer with a developed upper soil wedge: the end of MIS 3. Second, the layer under the dark brown clay layer with grain size roughening and a reddish tint: the second half of MIS 3. Third, the layer within the fluvial deposits under the dark brown clay layer: the second half of MIS 3. Fourth, the reddish-brown clay layer with a developed lower soil wedge and the layers under it: the first half of MIS 3~MIS 5, Lastly, the layers in the flowing water deposition under the reddish-brown clay layer: the first half of MIS 3 or earlier. Thus, the handaxes are related with the MIS 5 to MIS 3.
The artifact composition and spatial distribution varied between sites as the influence of slope deposits. In addition, Differences in micro-environments and temporal gaps, including differences in the energy of slope deposition between sites, had different effects on sites formation and post-depositional processes.

Recently, there has been growing interest in preschool-elementary transition education, as the 2019 revised Nuri Curriculum and the 2022 revised Elementary Education Curriculum emphasize connectivity between educational institutions, and the number of pilot kindergartens implementing transition semesters is gradually increasing nationwide. In this context, this study analyzed the limitations of current transition education and explored ways to improve it. As a result of the study, it was confirmed that the target of preschool and elementary education should be expanded from 5 years old to all ages, and that the focus should be on improving the current quality of life of young children rather than preparing for elementary school. In addition, it was suggested that young children should be recognized as agents of action and that coexistence should be pursued while respecting the differences between early childhood education and elementary education. To this end, it is necessary to strengthen cooperative relationships in the educational community, and find ways to connect education that can be implemented at the level of early childhood education institutions even under realistic constraints. This study is significant in that it provides a theoretical foundation for a comprehensive and continuous child-centered approach to transition education and presents practical measures for implementation.

La llamada “pandemia social” es una problemática que ha surgido en los últimos meses por lo que existen pocos estudios realizados sobre la temática. En el presente trabajo se buscó identificar cómo la depresión, ansiedad, agresividad, paranoia y otros factores afectan la conducta de los adolescentes. Esto se realizó mediante tests de rasgos transitorios para medir su estado emocional, ofreiendoe una visión de la magnitud del impacto en la psique humana frente al estado de violencia social, sumado a la pobreza del medio. El grupo en estudio fue de 152 estudiantes, que laboran en una Institución Educativa en una de las zonas donde inició el conflicto. Los resultados de los cuatro tests indicaron que más de la mitad de la población estudiantil presentó problemas emocionales. Estos resultados denotaron que se debe realizar intervenciones inmediatas con la implementación de programas de apoyo mental, técnicas que incluyan manejo de estrés, terapias y grupos de apoyo, lo que mejoraría el rendimiento académico y la sana convivencia. Las políticas públicas deberían enfocarse en diversificar la economía, mejorar las oportunidades laborales, educativas y proporcionar ayuda a las familias de zonas de conflicto de la región costa.

Authors: Ahmad FRSC Dr. Malik Imtiaz
Published: November 2024

This article explores the intricate legal challenges associated with cross-border in vitro fertilization (IVF), focusing on the roles of bioengineering and bioinformatics in this rapidly evolving field. As advancements in reproductive technology push the boundaries of what is possible, patients increasingly seek IVF treatment abroad, often due to varying regulations, cost differences, and access to specific procedures. However, this trend introduces a complex web of legal and ethical issues, as laws governing IVF differ significantly across countries. The article examines the impact of bioengineering, including genetic screening and manipulation, on the success rates and risks of IVF. It also underscores the importance of bioinformatics in personalizing treatment plans and improving decision-making processes, thereby highlighting the significance of individualized care. Ethical considerations, such as consent, autonomy, and cultural differences, are discussed alongside the challenges of regulatory compliance for clinics operating in multiple jurisdictions. The future of IVF technology is considered, with an emphasis on the need for international collaboration to standardize laws and protect patient rights. Through case studies and practical advice, the article provides a comprehensive overview of how patients and clinics can navigate the legal landscape of cross-border IVF.

The study was about factors affecting formalization initiative of real estate in Tanzania. The specific objectives were to: examine the influence of a policy on formalization initiative of real estate agents, determine the effect of income flow on formalization initiative of real estate agents and analyze the effects of an agent’s association on formalization initiative of real estate agents in Tanzania. Descriptive research design was employed and utilized Mixed Method Approach (MMA). The population was 110 individuals where a sample of 86 respondents were chosen. Simple random sampling technique was used to select a sample of real estate agents to participate in the study while a census was used to select Ministry staff, local government authorities and subject matter experts. Questionnaire and interview were used to collect data. The study found that policy and agents association would highly influence formalization initiative of real estate agents. On the other hand, income flow would influence formalization initiative of real estate agents in a low manner. The correlation analysis found that policy development, income flow and agents association had coefficient of 0.782, 0.267 and 0.678 respectively. The regression analysis found that agent`s associations would impact real estate agents’ formalization by 48.2%, policy would impact real estate agents’ formalization by 70.1% while income flow would impact real estate agent’s formalization by 5%. The study recommends that the government should come up with policy to guide the real estate agents, the real estate agent should organize themselves and register an organization to be able to channel their issues through the organization and that the government should come up with means to regulate income from the business of real estate agents.

Small and medium-sized enterprises (SMEs) are critical to Lebanon's economic structure, contributing significantly to employment and economic growth. However, one of the key challenges SMEs face is maintaining robust financial performance in an increasingly competitive and volatile business environment (Mekdessi et al., 2023). While much attention has been placed on technical skills development, the role of soft skills training in enhancing financial performance has been relatively underexplored. This research examines how soft skills, such as communication, leadership, emotional intelligence, and problem-solving, directly influence the financial metrics of Lebanese SMEs. Through a quantitative analysis of SMEs that have integrated soft skills training into their development programs, this study demonstrates that such training significantly improves financial outcomes, including profitability, operational efficiency, and customer satisfaction. These findings highlight the critical importance of a balanced skillset—one that incorporates both technical competencies and soft skills—to ensure the long-term success and competitiveness of SMEs in Lebanon. Practical recommendations are provided for SME leaders to incorporate soft skills training as part of their strategic development to drive financial growth.
SCREENING HETEROSIS IN HYBRID YEAST CELLS FOR THEIR LEAVENING PROPERTIES UNDER OSMOTIC STRESS

Published: November 2024

Bread-making industry occupies an important place in the food sector. This industry is in full process of expansion and automation for obtaining good quality and cost-efficient products. Hybridization in yeast gives rise to offspring carrying an admixture of both parental genotypes which display unique traits that may drive adaptation to changing environments. This study aimed to evaluate the fermentation performance of hybrid yeast cells under sucrose stress, as well as, to elucidate the role of fermentation time in decreasing the weight of fermented bread dough. Two hybrids originated from two hybridizations between three diverged strains of Saccharomyces cerevisiae were used in this study. Hybrids were characterized concerning the parental strains in a wort fermentation of bread wheat containing four sucrose concentrations. Hybrid genotypes have apparent hybrid vigor for reducing the weight of fermented bread dough over time than their parents. This indicated faster fermentation and producing higher quantities of CO2 leading to a decrease in the weight of fermented bread dough under sucrose stress up to 6 g /325 g wheat flour. Results apparent a strong positive correlation in the association between the decrease in fermented bread dough weight and fermentation time. Both variables vary in the same direction because they are dependent on each other. Results suggest that hybrid yeast genotypes are suitable for bread bread-making industry because of their unique properties in fermentation ability and producing high carbon dioxide leading the weight of fermentation bread dough to decrease over time.
