Authors: Etarh Franklin , Österman Karin
Published: January 2025

The aim of the study was to investigate symptoms of PTSD among women from the Anglophone regions of Cameroon related to the secessionist armed conflict that has been ravaging the regions since 2016.Three hundred and two women from four cities in the restive Anglophone regions of Cameroon and Douala, one of the Francophone regions, completed a questionnaire measuring PTSD. Of the respondents, 55.3 % had been kidnapped, and 36.1 % had been raped during the conflict. A significantly higher percentage of internally displaced women had been victimised compared to others. They also suffered significantly more often from symptoms of PTSD due to the conflict. Both kidnapped and raped women reported significantly higher scores on PTSD than non-victimised women; both groups reported anger and aggression and trouble remembering the conflict. Kidnapped women also reported specifically strong negative feelings like fear, horror, and shame, while raped women reported higher scores on having trouble experiencing positive or loving feelings, and experienced strong physical reactions when reminded of the conflict. The study revealed that PTSD among women from the Anglophone regions of Cameroon was related to victimisation from kidnapping, rape, and internal displacement during the secessionist armed conflict.
Application of Z-Numbers for Evaluation and Aggregation of the Travel Threats in the Post-Pandemic Era
Authors: Nuriyev Aziz
Published: January 2025

The purpose of this paper is a study of the applicability and efficiency of the Z-numbers (Zadeh, 2011) for estimation of the various travel risk factors, aggregation, and evaluation of the overall risks of the different destinations.  At present, travel risk analysis is mainly carried out by using the available statistical data about target country. Therefore, the possibilities of analysing the risks of travelling to a country/region, with insufficient or unreliable information remain questionable. Moreover, the sharp decline of the number of tourists travels due to the COVID-19 pandemic could lead to a decrease of the amount of necessary statistic data. To improve quality of the risk assessment, especial in post-pandemic era, the procedures of the Z-numbers based risks identification, assessment and risks aggregation are suggested. Expert’s predictions of the risks are formalized as Z-number-based evaluations. This approach allows considering reliability of the information. For aggregation of the tourist threats of different nature, the method for calculation of Z-weighted arithmetic means was proposed, the overall risk was determined by aggregating factors and a riskier direction was identified. Suggested approach provided an opportunity to go beyond the country-specific statistic-based risk assessment. Tourism risks assessment by using of Z-numbers as well as the proposed method of risks aggregation allows to conduct a comparative analysis of the risks, travelling to different destinations, even in conditions of large uncertainty.

Authors: Archana B , Charani Yallapragada Sahithi Sri , Sofia Umama , Fatima Salwa , Unnisa Tihama khair , A Rubeena
Published: January 2025

The present study examined the phytochemical and antimicrobial properties of a methanolic bark extract from a cork tree (Genus Phellodendron). Alkaloids, carbohydrates, steroids, reducing sugars, oils and fats, gums, volatile oil, flavonoids, proteins, amino acids, cysteine, anthraquinone glycoside, tannins, and phenolic chemicals were all found during the phytochemical screening. Due to the presence of oils, non-reducing polysaccharides and saponin glycoside were not present, and the solubility test verified insolubility in 90% ethanol and water. Studies on phytochemicals and antimicrobials were conducted using 95% methanolic extracts. The four test organisms employed in antibiotic investigations were staphylococcus aureus, Escherichia coli, Enterococcus species, and Pseudomonas auriginosa. Two techniques were used to experiment: the disc-diffusion method and the cup-plate approach.Given that the methanolic extract's Minimal Inhibitory Concentrations (MIC) were roughly 256 µg/ml, it is clear that cork trees have antimicrobial properties. Their mode of action may involve blocking the synthesis of proteins at the transcriptional or translational level or peptidoglycan synthesis at the membrane level. The presence of marmine (immature bark) and fagarine (mature bark), which also have antiulcer and abortifacient properties, may be the cause of the bark extract's antibacterial qualities. The findings offer encouraging baseline data for the possible application of this plant and some of its components in managing microbial illnesses.

Published: January 2025

The demand in the agricultural sector is on the rise, which is indirectly linked to the
accumulation of agricultural wastes via post-harvest operation, transportation, wholesale,
retail, storage, processing and packaging, which occurs in the food supply chain has been
one of the major challenges faced globally. Agricultural wastes contain diverse types of
bioactive compounds, which can be further utilised for the enhancement of food values. In
the present review, several water-based extractions were discussed including maceration,
digestion, infusion, decoction, percolation, Soxhlet, hydrodistillation, steam-distillation,
ultrasound-assisted and microwave-assisted extraction. The comparisons were based on
the polyphenol content and antioxidant activities focussing on pomegranate peel
(POMEP). This review discussed various polyphenol compounds found in POMEP
(ellagic acid and punicalagin) that contributed to antioxidant activities. It was found that
the acceptable limit of radical scavenging activities of POMEP was 65% in water-based
extractions, respectively. POMEP revealed that water-based maceration, digestion,
infusion, decoction, ultrasound-assisted and microwave-assisted extraction showed
acceptable antioxidant activities. Therefore, water-based extractions portrayed great
potential to be assimilated into the market based on their antioxidant potential and their
non-toxic and environment-friendly characteristics. This review is important to food
industries and stakeholders to further explore the possibilities of utilising fruit peels as
functional food products.

Authors: Zhang Yunlong , Wang Zengqiang
Published: January 2025

In order to deal with the complexity of logistics system evaluation under mass customization environment, multiple heterogeneous evaluators often directly give the language information of logistics system evaluation, and a logistics system evaluation method based on group language information is proposed. In this method, firstly, the evaluator uses language information to represent the evaluation value of the key indicators of the logistics system in the mass customization environment, and then uses fuzzy language scale to transform the evaluation value. Secondly, the Generalized Induced Ordered Weighted Averaging (GIOWA) operator is used twice to aggregate the language information given by the evaluator with the weight of the indicator and the weight of the evaluator to obtain the comprehensive evaluation value of the member and the comprehensive evaluation value of the scheme. Finally, the comprehensive evaluation values of the scheme are sorted and the optimal scheme is obtained. This paper takes a computer enterprise to realize the mass customization model as an example to verify the effectiveness and practicability of the proposed method.

Authors: Almajed Hasan , Jalili Yusuf
Published: January 2025

Background: Surgical Site Infections (SSI) impose a critical complication following lower segment cesarean sections (LSCS), contributing significantly to maternal morbidity and mortality. Understanding the risk factors associated with SSI is essential for improving clinical outcomes and enhancing patient care. This study aimed to identify the rate and risk factors associated with SSI among women who underwent LSCS at Salmaniya Medical Complex (SMC) in Bahrain.

Methods: A retrospective observational study was conducted at SMC in the period between 2020 and 2023. All patients with SSI post-LSCS and a comparable sample of patients who underwent LSCS but had no SSI were included. Data including patient demographics, clinical characteristics, and specific risk factors related to SSI were collected from electronic medical records. Descriptive and inferential analyses were done.

Results: The rate of SSI was 2.1% among women who underwent LSCS in SMC. Predictors of higher rates of SSI post-LSCS included having an emergency LSCS (odds ratio [OR]=4.14), a longer hospital stay (OR 1.37), and pre-operative stage 1 hypertension (OR=2.66), while diabetes mellitus (OR=0.29) and post-operative elevated laying blood pressure were linked to a reduced risk (OR=0.42) of postLSCS SSI.

Conclusion: This study revealed a low rate of post-LSCS SSI. This study highlighted the implications of emergency procedures, hospital stay duration, and blood pressure management. The paradoxical protective effect of diabetes mellitus warrants further investigation. These insights are pivotal for developing targeted interventions aimed at minimizing SSI, thereby enhancing maternal health outcomes in clinical practice.

Economic, social, and crop management and environmental factors are important for the development and establishment of successful productive units. The objective of this study was to evaluate the interactions between the characteristics of productive units and the perceptions of producers. Different areas of performance were considered in the establishment of lemon and avocado crops in the municipality of Calvillo, Aguascalientes, Mexico.49 agricultural producers who carried out productive reconversion of their parcels for the establishment of lemon and avocado crops were interviewed. Semi-structured surveys were applied to evaluate the characteristics of the management and operation of the agricultural farms. Likewise, the perceptions of producers were measured in the economic (ECO), social (SOC), and environmental (CULT/AMB) areas. Through a PERMANOVA and binary logistic models, the groups of variables analyzed were simultaneously analyzed. The areas analyzed (ECO, SOC, and CULT/AMB) were found to be significantly affected (p<0.001) by the source of water, the expectations of continuity of the farms, and the crop prior to productive reconversion. The novelty of these findings demonstrates the importance of decision-making for the establishment of alternative crops in the search for higher incomes by agricultural producers and to ensure the continuity of productive farms for the development of rural areas. Doi: 10.28991/HEF-2024-05-04-01 Full Text: PDF

Published: January 2025

Candlenut (Aleurites moluccanus) is a plant that has active components and is believed to have medical benefits in every part of this plant. This study aims Identified the active compounds in the ethanol extract of candlenut leaves from the Seulawah Mountains, Aceh, Indonesia, and evaluated their effectiveness in reducing inflammation through the inhibition of TNF-α. The extraction of candlenut leaves was conducted using ethanol as a solvent. The active compounds in the candlenut leaves extract were identified using phytochemical screening, the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, gas chromatography-mass spectrometry (GC-MS), and their biological activity was assessed using molecular docking. This study further examined the effects of candlenut leaves extract on wound healing in male white rats in vivo and the inhibition of TNF-α levels using the ELISA method through candlenut leaves extract mouthwash formulations at concentrations of 12.5%, 25%, and 50%. Phytochemical screening results revealed that the ethanol extract of candlenut leaves contains abundant secondary metabolites, including alkaloids, flavonoids, steroids/terpenoids, tannins, phenols, and saponins. Antioxidant analysis demonstrated that the ethanol extract exhibited strong antioxidant activity with an IC50value of 89.221 ppm. GC-MS analysis identified 54 individual compounds in the extract, with five major compounds: n-hexadecanoic acid, isophytol, 9,12-octadecanoate-1-ol, octadecanoic acid, and squalene. These major compounds have significant bioactivities, including antioxidant, antibacterial, and antimicrobial properties. Molecular docking tests identified stigmasta-5,22-dien-3-ol and cycloheptadecanol as showing strong docking activity against TNF-α. Rats treated with the extract showed significant wound size reduction over 14 days, along with an increase in body weight. The extract also demonstrated an inhibitory effect on TNF-α concentration based on the dosage used. The anti-inflammatory effect of certain active compounds can reduce the regulation of specific cytokines, thereby inhibiting inflammation. These findings suggest that the active compounds in the ethanol extract of candlenut leaves have the potential to inhibit TNF-α, a key of pro-inflammatory cytokine, through significant antioxidant and anti-inflammatory activities. Doi: 10.28991/HEF-2024-05-04-010 Full Text: PDF

The rapid integration of modern technology, coupled with the pandemic, has triggered a seismic shift in the landscape of SME hotel business, profoundly influencing the mindset and actions of hotel entrepreneurs and their customers. This study aims to identify the factors affecting customer value creation of SME hotels and links customer needs with hotel operators and local communities. 415 completed survey respondents from an initial screening of 655 active social network accounts who have been SME hotel customers in the past 12 months account for a 63.4% response rate. The findings reveal how the four factors designated by customers and SME hotels influence customer value co-creation: information sharing, participation, knowledge management from local expertise, and expanding local community networks knowledge. The novelty of this study is to develop and validate precise factors for creating value, which will affect the value that customers receive. This study demonstrates methodological advances through Structured Equation Modeling (SEM) and highlights customer preferences that can be implemented to improve SME hotel strategy and promote long-term sustainability. Further research will enable the idea of an innovative model of customer value co-creation to continue for service and other retail businesses. Doi: 10.28991/HEF-2024-05-04-014 Full Text: PDF

This study aims to identify the most suitable Enterprise Architecture (EA) framework for driving digital transformation within Malaysia's agricultural sector. The objective is to evaluate and compare four leading EA frameworks—the Zachman Framework (ZFEA), the Department of Defense Architecture Framework (DoDAF), the Federal Enterprise Architecture Framework (FEAF), and The Open Group Architecture Framework (TOGAF)—using eight key criteria: adaptability, scalability, ease of implementation, support for modern technologies, cost-effectiveness, compliance, traceability, and risk management. A systematic comparative analysis assessed these frameworks' effectiveness in addressing the agricultural sector's specific needs. The findings indicate that TOGAF is the most appropriate framework due to its high adaptability, scalability, and robust support for modern technologies, making it ideal for the sector's requirements. In contrast, ZFEA, though versatile, faces significant challenges in practical implementation and scalability. DoDAF’s defense-centric focus limits its applicability in agriculture, and while FEAF is adaptable, it lacks strong support for modern technological integration. This study provides novel insights and practical recommendations for policymakers and practitioners to select the most effective EA framework, thereby supporting Malaysia's agricultural sector's digital transformation and modernization. Doi: 10.28991/HEF-2024-05-04-015 Full Text: PDF

Published: January 2025

This research intends to build an optimal curve model of reservoir water level fluctuation for real-time water supply operation and to build an information system of gate opening operation due to the real-time release of reservoir storage by considering water demand and flood capacity in the downstream. The proposed methodology combines the update of an optimized rule curve forecast based on 10-dayly inflows projected for the next three months and the optimization of early release volumes based on hourly reservoir routing inflows over the upcoming two days. The water balance simulation is conducted to optimize the irrigation water release-to-demand ratio (K Factor) by considering both deterministic and stochastic inflow scenarios. Real-time reservoir routing simulation is performed to optimize gate openings with the constraint of maintaining the end-of-period water level in line with the updated ten-daily rule curve forecast. This research is conducted in the Dodokan Watershed with the cascade reservoir of Batujai and Pengga. Simulations indicate that optimized gate openings—two gates at 0.4 m and two at 0.2 m for Batujai (with an inflow of 638.7 m³/s) and 0.3 m on Pengga's sixth gate (with an inflow of 616.3 m³/s)—effectively prevent downstream flooding, maintaining reservoir levels within safe limits under High Flood Water Levels (HFLW) and ensuring water supply continuity. With an average K factor effectiveness of 83% for stochastic inflow prediction and 79% for deterministic inflow prediction, the optimized model adjusts spillway operations in real time, ensuring enhanced flood control and operational safety by aligning with real-time rule curves. Doi: 10.28991/HEF-2024-05-04-03 Full Text: PDF

Published: January 2025

In recent years, significant transformations have occurred in urban systems and their management by enhancing and developing governance through a comprehensive and organized framework based on multiple studies and methods in city management, particularly in the environment and energy sectors. To achieve a balance in the utilization of natural resources and improve the quality of life, the research aims to transform energy into sustainable forms, known as renewable energies, through urban governance as a transitional approach in traditional energy systems and the establishment of long-term sustainable planning systems through self-organizing governance work. This method enables all city sectors to rely on clean energy sources by creating digital governance maps to determine the future directions of cities, bridge gaps, and solve pollution problems and environmental issues. The goal is to develop flexible cities with advanced communications technology and digital governance capable of managing their systems independently. These efforts provide an organized and integrated approach to sustainability assessment, which is an essential part of the city planning process, including the classification and evaluation of alternatives and plans. By analyzing data through SPSS and utilizing Cronbach's Alpha, the research evaluates energy-related factors affecting the sustainability of cities by assessing suitability and quality criteria. Doi: 10.28991/HEF-2024-05-04-04 Full Text: PDF
