Authors: Yun Jiawen , Jin Shanyue
Published: April 2024

Green finance, an essential tool for high-quality economic development, is valued by policymakers and researchers in line with the growing global concern for environmental protection, climate change, and sustainable development. The banking sector, as a major part of China’s green financial system, undertakes significant responsibility for green finance while also confronting the opportunities and requirements of digital transformation. Big data technology is a major driver of digital transformation in the banking sector and can improve the green operational capability of the banking sector. The purpose of this study is to explore the ways in which the extent of big data technology transformation in the banking sector in China affects its ability to operate in a green manner and to analyze the moderating role of green credits, funds, and bonds. For this reason, this study selected A-share listed banks in China from 2015 to 2022 as research subjects and adopted a panel data regression method to study the impact of the degree of big data technology transformation on green operations. The results demonstrate that the degree of big data technology transformation in the banking sector positively influenced green operations. Green credit, funds, and bonds played a moderating role, meaning that financial products strengthened the role of the degree of big data technology transformation in green operations. This study examined the effect of big data technology transformation in the banking sector and enriches research on green finance. This study also provides practical insights for investors and regulators concerned with green development in the banking sector.

Authors: Tsappi Elena , Deliyannis Ioannis , Papageorgiou George Nathaniel
Published: April 2024

In response to the transformative impact of digital technology on education, this study introduces a novel performance management framework for virtual learning environments suitable for the metaverse era. Based on the Structural Equation Modeling (SEM) approach, this paper proposes a comprehensive evaluative model, anchored on the integration of the Theory of Planned Behavior (TPB), the Unified Theory of Acceptance and Use of Technology (UTAUT), and the Community of Inquiry Framework (CoI). The model synthesizes five Key Performance Indicators (KPIs)—content delivery, student engagement, metaverse tool utilization, student performance, and adaptability—to intricately assess academic avatar performances in virtual educational settings. This theoretical approach marks a significant stride in understanding and enhancing avatar efficacy in the metaverse environment. It enriches the discourse on performance management in digital education and sets a foundation for future empirical studies. As virtual online environments gain prominence in education and training, this research study establishes the basic principles and highlights the key points for further empirical research in the new era of the metaverse educational environment.

Published: April 2024

SDN has the ability to transform network design by providing increased versatility and effective regulation. Its programmable centralized controller gives network administration employees more authority, allowing for more seamless supervision. However, centralization makes it vulnerable to a variety of attack vectors, with distributed denial of service (DDoS) attacks posing a serious concern. Feature selection-based Machine Learning (ML) techniques are more effective than traditional signature-based Intrusion Detection Systems (IDS) at identifying new threats in the context of defending against distributed denial of service (DDoS) attacks. In this study, NGBoost is compared with four additional machine learning (ML) algorithms: convolutional neural network (CNN), Stochastic Gradient Descent (SGD), Decision Tree, and Random Forest, in order to assess the effectiveness of DDoS detection on the CICDDoS2019 dataset. It focuses on important measures such as F1 score, recall, accuracy, and precision. We have examined NeTBIOS, a layer-7 attack, and SYN, a layer-4 attack, in our paper. Our investigation shows that Natural Gradient Boosting and Convolutional Neural Networks, in particular, show promise with tabular data categorization. In conclusion, we go through specific study results on protecting against attacks using DDoS. These experimental findings offer a framework for making decisions.

Published: April 2024

Bisphenol A (BPA), an acknowledged endocrine disrupter, is easily exposed to humans via food packaging and container. However, a consensus has not been reached on the extent to which BPA exposure affects the reproductive system. We therefore conducted this systematic review and meta-analysis to elucidate the relationship between BPA exposure and male reproduction-related indicators. Up to October 2023, a comprehensive search was carried out in the PubMed, Embase, Cochrane and Web of Science, and 18 studies were ultimately included. β coefficients from multivariate linear regression analyses were pooled using a random effects model. The results showed that the urinary BPA concentration was negatively correlated with the sperm concentration (β coefficient = −0.03; 95% CI: −0.06 to −0.01; I2 = 0.0%, p = 0.003) and total sperm count (β coefficient = −0.05; 95% CI: −0.08 to −0.02; I2 = 0.0%, p < 0.001). In addition, BPA concentrations were associated with increased sex hormone-binding globulin (SHBG) levels, increased estradiol (E2) levels, and reduced biologically active androgen levels. However, the relationship between an increased risk of below-reference sperm quality and BPA exposure was not robust. This systematic review revealed that BPA exposure disrupts reproductive hormones, reduces sperm counts and may ultimately adversely affect male reproduction.
Critical Environmental Injustice: A Case Study Approach to Understanding Disproportionate Exposure to Toxic Emissions
Authors: Cannon Clare E. B.
Published: April 2024

Environmental justice research has focused on the distribution of environmental inequalities, such as proximity to landfills, across the U.S. and globally. Background: Public health research and environmental health research, specifically, have focused on toxic exposure—encompassing individuals or communities that are disproportionately exposed to contaminants that are harmful or potentially harmful to them. Yet, little research has applied critical environmental justice theory—characterized by the idea that marginalized communities need to be treated as indispensable rather than disposable—to the study of toxic exposure. To fill this gap, the current paper offers a case study approach applying critical environmental justice theory to the study of disproportionate and unequal exposure to toxic contaminants. Methods: This case study is of Kettleman City, a rural, unincorporated community in the heart of California’s Central Valley (USA). This community experiences the co-location of environmental hazards, including residing at the intersection of two major highways and hosting a class I hazardous-waste landfill, which is one of the few licensed to accept PCBs. PCBs are a contaminant that has been linked with several adverse health outcomes, including cancers and low birthweight. Residents may also experience poor air quality from proximity to the highways. Results: This case highlights the uneven distribution of pollution and environmental degradation that may be shouldered by the community, along with their experiences of adverse health and social impacts. This analysis reveals the importance of incorporating a critical environmental justice perspective to unpack experiences of not only disproportionate exposure but also disproportionate procedural and recognitional inequality. Conclusions: This research highlights the untapped potential of environmental justice to catalyze exposure science in challenging the unequal distribution of contaminants.

Authors: Nikolov Nikolay , Petkova Tsvetelina , Binev Rumen , Milanova Aneliya
Published: April 2024

Mycotoxin binders, in combination with enzymes degrading some mycotoxins, contribute to feed detoxification. Their use reduces economic losses and the negative impacts of mycotoxins on animal health and productivity in farm animals. The aim of this study was to evaluate the efficacy of a mycotoxin detoxifier on the expression of the ATP-binding cassette efflux transporters ABCB1 mRNA and ABCC2 mRNA, which transport xenobiotics and thus have a barrier function, in the tissues of pigs exposed to low doses of deoxynivalenol (DON, 1 mg/kg feed) and zearalenone (ZEN, 0.4 mg/kg feed) for 37 days. The levels of expression were determined by an RT-PCR, and the effect of the mycotoxin detoxifier (Mycofix Plus3.E) was evaluated by a comparison of results between healthy pigs (n = 6), animals treated with DON and ZEN (n = 6), and a group that received both mycotoxins and the detoxifier (n = 6). A significant downregulation of ABCB1 mRNA and ABCC2 mRNA was observed in the jejunum (p < 0.05). A tendencies toward the downregulation of ABCB1 mRNA and ABCC2 mRNA were found in the ileum and duodenum, respectively. The mycotoxin detoxifier restored the expression of ABCB1 mRNA to the level found in healthy animals but did not restore that of ABCC2 mRNA to the level of healthy animals in the jejunum.

Published: April 2024

Background: Infective endocarditis (IE) is a serious condition which is difficult to diagnose and to treat, both medically and surgically. Objectives: The objective of this study was to evaluate the impact of the SARS-CoV-2 pandemic on the management of patients with IE. Methods: We conducted a single-centre retrospective study including patients hospitalized for IE during the pandemic (Group 2) compared with the same period the year before (Group 1). We compared clinical, laboratory, imagery, therapeutic, and patient outcomes between the two groups. Results: A total of 283 patients were managed for possible or definite IE (164 in Group 1 and 119 in Group 2). There were more intravenous drug-related IE patients in Group 2 (p = 0.009). There was no significant difference in surgery including intra-cardiac device extraction (p = 0.412) or time to surgery (p = 0.894). The one-year mortality was similar in both groups (16% versus 17.7%, p = 0.704). The recurrence rate was not significantly different between the two groups (5.9% in Group 2 versus 9.1% in Group 1, p = 0.311). Conclusions: The SARS-CoV-2 pandemic did not appear to have had a negative impact on the management of patients with IE. Maintenance of the activities of the endocarditis team within the referral centre probably contributed to this result. Nevertheless, the high proportion of intravenous drug-addicted patients in the pandemic cohort suggests that the SARS-CoV-2 pandemic had a major psychosocial impact.
Global, Regional and National Burden of Human Cystic Echinococcosis from 1990 to 2019: A Systematic Analysis for the Global Burden of Disease Study 2019
Authors: Tian Tian , Miao Liyuan , Wang Wei , Zhou Xiaonong
Published: April 2024

Background: Cystic echinococcosis (CE) is a neglected tropical parasitic disease that poses huge disease, social and economic burdens worldwide; however, there has been little knowledge on the global morbidity, mortality and disability-adjusted life years (DALYs) of CE until now. This study aimed to collect the most up-to-date data about the global, regional and national disease burden due to CE from 1990 to 2019 and to project trends in the next 10 years. Methods: We measured the global, regional and national morbidity, mortality and DALYs of CE from 1990 to 2019 based on the Global Burden of Disease Study 2019 (GBD 2019) data, and we examined the correlation between socioeconomic development levels and the disease burden of CE. In addition, the disease burden due to CE was projected from 2020 to 2030. Results: The age-standardized incidence rate (ASIR) of CE reduced from 2.65/105 [95% UI: (1.87/105 to 3.7/105)] in 1990 to 2.6/105 [95% UI: (1.72/105 to 3.79/105)] in 2019 (EAPC = −0.18%). The number of deaths, DALYs, age-standardized mortality rate (ASMR) and age-standardized DALY rate due to CE all showed a tendency to decline from 1990 to 2019. A higher disease burden of CE was measured in women than in men in 2019. There was a significant difference in the ASMR of CE by region according to the socio-demographic index (SDI), and lower burdens of CE were estimated in high-SDI regions. The global ASIR of CE is projected to decline from 2020 to 2030; however, the ASMR and age-standardized DALY rate are projected to rise. Conclusions: The global burden of CE remains high, and it is recommended that more health resources are allocated to low-SDI regions, women and the elderly aged 55 to 65 years to reduce the disease burden of CE.

Published: April 2024

In the realm of antenatal care, vaccinations serve as a cornerstone, crucial for safeguarding the health of both the mother and the fetus, while also extending protection to the newborn against communicable diseases. Nevertheless, vaccine adherence among pregnant women remains very low. The aim of our study was to evaluate the uptake of vaccines (influence, pertussis, and COVID-19) among women during pregnancy and to understand pregnant women’s knowledge of vaccines and the diseases they protect against. The purpose was to investigate the reasons why pregnant women chose not to be vaccinated and to develop effective strategies for informing them about the importance of vaccination for both maternal and fetal safety. A prospective observational study was conducted in the Department of Obstetrics and Gynaecology, “Ospedale Santa Maria della Misericordia” in Udine, from 1 December 2021 to 30 June 2022. During this period, a self-completed paper questionnaire was administered to women at the end of pregnancy or during the puerperium. A total of 161 questionnaires were collected. Higher educational level was found to be significantly associated with influenza vaccination uptake (p = 0.037, OR = 2.18, 95% CI 1.05–4.51). Similarly, for pertussis vaccination, adherence was mainly associated with higher educational level (p = 0.014, OR = 2.83, 95% CI 1.24–6.47), but also with Italian nationality (p = 0.003, OR = 3.36, 95% CI 1.56–8.43) and pregnancy attended by a midwife or private gynecologist (p = 0.028, OR = 0.39, 95% CI 0.17–0.90). Regarding the COVID-19 vaccine, the only factor positively influencing uptake was Italian nationality (p = 0.044, OR = 2.66, 95% CI 1.03–6.91). Women’s fear that vaccines would endanger the fetus appeared to be the most important reason for refusing vaccinations. Simultaneously, patients also exhibited a desire to receive more information about maternal vaccination, particularly from their general physician or gynecologist. For this reason, it is imperative to enhance maternal vaccination counselling, making it a routine step in prenatal care from the first antenatal visit until the postpartum period.
Influence of Fluvial Discharges and Tides on the Salt Wedge Position of a Microtidal Estuary: Magdalena River
Authors: Cordero-Acosta Jhonathan R. , Otero Díaz Luis J. , Higgins Álvarez Aldemar E.
Published: April 2024

The linkage between the salt wedge, tidal patterns, and the Magdalena River discharge is established by assessing the ensuing parameters: stratification (ϵ), buoyancy frequency (β), potential energy anomaly (φ), Richardson number by layers (RL), and bottom turbulent energy production (P). The salinity, temperature, density, and water velocity data utilized were derived from MOHID 3D, a previously tailored and validated model for the Magdalena River estuary. To grasp the dynamics of the river, a flow regime analysis was conducted during both the wet and dry climatic seasons of the Colombian Caribbean. The utilization of this model aimed to delineate the estuary’s spatial reach, considering flow rates spanning from 2000 to 6500 m3/s across two tidal cycles. This approach facilitates the prediction of the position, stability, and stratification degree of the salt front. Among the conclusions drawn, it is highlighted that: 1. The river flow serves as the principal conditioning agent for the system, inducing a strong estuary response to weather stations; 2. The extent of wedge intrusion and the river discharge exhibit a non-linear, inversely correlation; 3. Tidal waves cause differences of up to 1000 m in the horizontal extent of the wedge; 4. Widespread channel erosion occurs during the rainy season when the salt intrusion does not exceed 2 km; 5. Flocculation processes intensify during the transition between the dry and wet seasons; 6. The stability of the salt layering and the consolidation of the FSI–TMZ are contingent upon the geometric attributes of the channel.

Published: April 2024

In engineering and transportation, beams are frequently utilized as structural elements for both static and dynamic loads. This paper focuses on a smart structure method that incorporates ANSYS software for modeling and simulation. Piezoelectric transducers are employed for actuation and sensing throughout the structure. The governing equation of a finite element that converts the mechanical energy of the structure into the electric energy of the piezoelectric material is derived using Hamilton's principle. Debonding of piezoelectric sensors/actuators is caused by structural alterations in sandwich beams, and this leads to a notable fluctuation in both static and dynamic responses. It has been shown that Finite Element Modeling with ANSYS software yields accurate numerical solutions over a broad range of related parameters. The results are displayed and vibration modes are animated by utilizing the graphical post processing capabilities. It has been observed that the material and structural alterations are what cause the increase in natural frequencies. With an input of 1 V, the load is adjusted between 0 and 5000 Hz for every material configuration.

Published: April 2024

During the COVID-19 pandemic, mRNA vaccines emerged as a rapid and effective solution for global immunization. The success of COVID-19 mRNA vaccines has increased interest in the use of lipid nanoparticles (LNPs) for the in vivo delivery of mRNA therapeutics. Although mRNA exhibits robust expression profiles, transient protein expression is often observed, raising uncertainty regarding the frequency of its administration. Additionally, various RNA therapeutics may necessitate repeated dosing to achieve optimal therapeutic outcomes. Nevertheless, the impact of repeated administrations of mRNA/LNP on immune responses and protein expression efficacy remains unclear. In this study, we investigated the influence of the formulation parameters, specifically ionizable lipids and polyethylene glycol (PEG) lipids, on the repeat administration of mRNA/LNP. Our findings revealed that ionizable lipids had no discernible impact on the dose-responsive efficacy of repeat administrations, whereas the lipid structure and molar ratio of PEG lipids were primary factors that affected mRNA/LNP performance. The optimization of the LNP formulation with PEG lipid confirmed the sustained dose-responsive efficacy of mRNA after repeated administrations. This study highlights the critical importance of optimizing LNP formulations for mRNA therapeutics requiring repeated administrations.

Published: April 2024

In the Yellow River Basin, the lack of water supplies is now the largest obstacle to both environmental preservation and socioeconomic growth. The fact that inhabitants’ diets may be altered to save water, however, is gravely underappreciated. Based on the water footprint theory, we examined the water footprint structure and the dynamic evolution process of food consumption in the Yellow River Basin from 1999 to 2019 in this study. The key factors affecting the water footprint of food consumption were then identified by using the STIRPAT model modified by the partial least-squares method. The findings indicate the following: (a) There had been an increase in the Yellow River Basin’s overall water footprint of food consumption from 1999 to 2019, with the midstream region having the biggest water footprint of food consumption (410.8 billion m
3
) and the highest percentage increase (86%). (b) In the Yellow River Basin, the water footprint of meat eating was 36% while the water footprint of grain consumption was 30%. The lower Yellow River had the greatest water impact per person due to food consumption. (c) Urbanization rate played a promoting role in the upper Yellow River provinces, and GDP and irrigated area played a promoting role in the lower Yellow River provinces. The results of this study are expected to provide scientific support for the decision-making of healthy and water-saving diets in the Yellow River basin.

Published: April 2024

Background. Training efficient human resources is one of the main missions of universities. Considering the role of education in the development of professional human resources in the health system, it is essential to evaluate the status of the educational system in Iranian universities. The present study aimed to identify and prioritize the challenges in the educational system of Tabriz University of Medical Sciences as well as to provide solutions for dealing with them based on the viewpoints of investors (i.e., faculty members, students, managers, and teaching staff of the university). Methods. This mixed method study (i.e., qualitative-quantitative study) was conducted in Tabriz University of Medical Sciences in the summer of 2023. The total number of the participants was 538, including 138 faculty members, 345 students, and 55 managers and employees in the field of education. The data collection tool in the qualitative phase of the study was an open-question questionnaire, but that in the quantitative phase was a closed-question one. The prioritization matrix was used to prioritize the challenges, which included four indicators of importance, solvability, cost-effectiveness, and urgency. Results. A lack of the space and suitable facilities for students during their internships and internships, a professors' workload, a lack of the connection between Tabriz university and other universities/educational centers, a failure to select educational authorities based on their qualifications and capabilities, and a lack of professors were the most serious educational challenges. Conclusion. The lack of suitable space and facilities for students during their internships and the insufficient number of professors were two of the most serious educational challenges at Tabriz University of Medical Sciences. Therefore, it was recommended that the authorities and managers of this university should pay urgent attention to these challenges and do careful planning to address them.

Published: April 2024

Background. Designing a payment system for healthcare workers- doctors and nurses, in particular- in the hospitals is more intricate than that for other organizations. Beyond the legal compliance, the unique features of the medical professions and nursing work environment should be considered. Due to the lack of adequate researches on payment methods for doctors and nurses in Iran, especially regarding the recent changes in "fee for services" (FFS) payment, the present study aimed to investigate the payment challenges faced by the doctors and nurses in Iranian public hospitals. Methods. Challenges were identified by interviews, and prioritized by adopting the MARCOS method. The study population included the hospital managers, healthcare payment method experts, and doctors and nurses in the public hospitals. Targeted sampling and semi-structured interviews were conducted to collect the data. In the MARCOS method, criteria determination, weighting, and scoring of the challenges were performed by five experts in the field of healthcare payment. Criteria included decreased motivation (25%), reduced productivity (15%), correction cost (40%), and implementation difficulty of the correction (20%). Calculations were performed using Excel software and determining the relevant priorities. Results. A total of 16 interviews were conducted in this study, with 10 interviews about the academic faculty and hospital managers in Isfahan University of Medical Sciences, three about the nursing experts in Tehran, and three about the Ministry of Health experts. According to MARCOS method calculations, the top 4 challenges in compensating doctors were identified as: low FFS ceiling, lack of job difficulty incentives, the inadequate impact of full-time work, and the progressive taxing. Additionally, the 2 primary challenges in compensating nurses were: irregular payment of FFS, and collective payment of FFS instead of individual payment. Conclusion. At the time of this study, Iranian public hospitals provided the doctors with individual rights, benefits, and allowances, while it provided the nurses with collective rights, benefits, and overtime pay. Although these compensation methods often posed different challenges, most of the issues were associated with the allowance payments. By prioritizing key challenges, authorities may have developed the necessary solutions for addressing the challenges as well as enhancing the satisfaction of doctors and nurses in Iranian public hospitals.

Published: April 2024

In this study, a double-shaft type sweet potato rice-planting and rice-returning machine was designed. The structure of the whole machine as well as the key components were analyzed, and the influence of each factor on the operation quality was studied. The results of the study showed that the order of the influence of each factor on the length of broken stems and leaves and the rate of checking was as follows: roller speed > toggle clearance > toggle spacing; the order of the influence on the stubble height was as follows: toggle clearance > roller speed > toggle spacing; and the order of the influence on the rate of injury to potatoes was as follows: roller speed = toggle clearance = toggle spacing. The optimal combination of working parameters in the field test was 1944 r/min for roll speed, 132 mm for toggle spacing, and 20 mm for toggle clearance, at which the qualification rate of stem and leaf breaking length was 94.32%, stubble height was 33.61 mm, and potato injury rate was 0.26%. The relative error with the theoretical optimization value is between 0.13% and 7.14%, which meets the operational requirements of sweet potato rice transplanter.
Developing the biological potential of organometallic cages
Authors:   , Pons Allé Santiago
Published: April 2024

Arene ruthenium metalla-assemblies are supramolecular structures which self-assemble through coordination forces. They are composed by different building blocks: clips and panels, the choice of which determines the final architecture of the assembly. This modular approach is what makes the functionalization of these systems most interesting, as different modifications can be introduced at the same time in a controlled manner. Three-dimensional structures such as prisms or cubes are possible, some of which possess a cavity capable of transporting hydrophobic molecules, making arene ruthenium assemblies relevant candidates for the design of novel drug delivery systems. The aim of this thesis is to investigate the synthetic pathways to functionalize metalla-assemblies and to study their combination to obtain multi-functional platforms for biological applications. In a first approach, trigonal panels with different functional groups have been synthesized and used to form prisms. Then, those panels have been combined with double-arm pyrenyl derivatives, acting as guests, proving that prisms with functionalized panels are able to encapsulate functionalized guests. The same strategy has been applied in the synthesis of a set of third generation photosensitizers, based on assemblies with a biotinylated panel for targeting, and three different pyrenyl-photosensitizer guests for photodynamic therapy (PDT) applications. Their phototoxic activity has been tested on HCT116 human colorectal cancer cells. Moreover, clips containing an oxamide spacer have been modified by introduction of functional groups such as alkylic chains with different amounts of hydroxyl groups or short PEG chains. These clips have been used in the synthesis of prisms and cubes to tune their water-solubility. Their hydrophilicity has been studied by calculating their octanol-water partition coefficient. Hydrophilic values have been obtained for both sets of samples.

The use of toothpaste in brushing teeth is an effort to control dental plaque, which is a sticky layer on the tooth surface that contains bacteria and serves as a predisposition for various oral diseases. Sungkai (Peronema canescens Jack) leaves are natural ingredients known for their antibacterial properties and are increasingly being used. This research aimed to test the antibacterial activity of gel toothpaste with Sungkai leaf extract against Streptococcus mutans bacteria. This study was a true-experimental design that compared the inhibitory effect of gel toothpaste with Sungkai leaf extract using the disk diffusion method at various concentration formulations (5%, 10%, 15%, 20%, and 25%) compared to the control. The results showed that the higher the concentration of Sungkai leaf extract, the inhibitory effect was also significantly increases (p < 0.005). At a concentration of 25%, it even had an inhibitory effect that was not significantly different from the control (p = 0.184). It can be concluded that gel toothpaste with Sungkai leaf extract is effective in inhibiting the growth of Streptococcus mutans bacteria.

Dental and oral health problems in Indonesia are still high, in this case dental caries and periodontal tissue disease. This disease occurs because of plaque that sticks to the surface of the teeth. The contents of plaque consist of microorganisms in the form of biofilm. This biofilm can affect the structure of the oral cavity. Controlling plaque accumulation can be done by gargling with boiled water. The mechanical effect of gargling can clean plaque on the surface of the teeth. Salan leaves (Syzgium polyanthum) and guava leaves (Psidium guajava Linn) have chemical effects, because they contain flavonoid compounds which can inhibit plaque growth. The aim of this research was to analyze the effectiveness of gargling boiled bay leaves (syzygium polyanthum) and guava leaves (psidium guajava linn) on reducing plaque index in students of the Department of Dental Health, Health Polytechnic, Ministry of Health, Manado. This type of research is quasi-experimental research with a pre-test and post-test design. This research was carried out by providing treatment to respondents and checking the plaque index before and after gargling with a decoction of bay leaves (syzygium polyanthum) and guava leaves (psidium guajava linn). The sample in this study amounted to 50 people. The data were analyzed using the t-test. Based on the results of the t-test, it was found that ? value=0.00 (0.00<0.05) meaning that there was a significant difference between before and after gargling with boiled bay leaves (syzygium polyanthum) and guava leaves (psidium guajava linn ). The results of this study also showed that there was a difference in the plaque index value after gargling with decoction of bay leaves (syzygium polyanthum) and guava leaves (psidium guajava linn), where the average value before gargling decoction of bay leaves was 2.7 and after 1 and had The difference in decrease was 1.7 points, while the average value before gargling with boiled guava leaves was 2.6 and after 1.1 and had a difference in decrease of 1.5 points. This shows that gargling with boiled guava leaves is more effective in reducing plaque accumulation compared to boiled bay leaves.

This study determinedthe gender differentials in the postharvest processing of kolanut. The study was carried out in Ondo State of Nigeria. Multistage random sampling technique was used to select respondents. Two kolanut producinglocal government areas (LGAs)Ife East and Ondo Eastwere purposively selected from the state. From Ife East, Ifekola was selected while Bolorunduro community was selected in Ondo East. A total of 150 kolanut processors were randomly selected from the two communities. Structured questionnaire was used to collect information from the respondents. The data retrieved from the information collected were analysed using descriptive statistics. Most (70.67%) of the respondents are 50 years and below while 29.33% of the respondents are above 50 years of age. About 64.67% of the marketers are females while 89.33% of the processors are married with 83.33% of the respondents having formal education. Ninety percent of adult femaleswere involved in the soaking of kolanuts in preparation for peeling and 10% of adult maleswere involved in the same activity. Also, for peeling of kolanuts activity,96.0% of adult femaleswere involved and 4% of adult male were involved. Ninety seven percent of adult female and 3% of adult male were involved in washing of the peeled kolanut. In the preservation of the peeled kolanut,86% of adult female and 14% of adult male were involved. Forty six percent of the processors agreed that it is always very difficult to get fresh kolanut to buy. In a similar manner, 52.67% of the respondents agreed that preservative chemicals are not always available to buy. As regards the labour availability for peeling, 45.33% of the respondents are of the opinion that labour for peeling isalways very difficult to attract. Some of the processors (32.67%),confirmed that leaves for storing kolanut is always very difficult to get. As regards the preservative chemicals, 54.67% of the processors believed that the chemicals are not always available to buy.In the study,more women are involved in all the activities involving kolanut processing than men. Women involved with kola production and marketing need to form groups to work togetherand purchase their materials in bulk from towns/cities near them

Insect pests pose a significant threat to maize (Zeamays) crops worldwide, leading to substantial yield losses and reduced agricultural productivity. Traditional control methods relying on synthetic pesticides have raised concerns regarding their environmental impact and potential health risks. Therefore, the search for eco-friendly and sustainable alternatives is essential. This study investigates the efficacy of natural extracts derived from Hyptissuaveolens(commonly known as wild mint), charcoal, and wood ash in the control of insect pests infesting maize crops. Research was conducted at an experimental unit at University of Ilorin in 2022 using a pot trial. The experiment employed a randomized complete block design, with treatments including ethanol extracts of Hyptissuaveolens, charcoal dust, and wood ash, as well as a control group with no treatment. A kilogram of wood ash, Hyptissuaveolensand charcoal each was soaked in 5liters of ethanol for 48hours. Each mixture was sieved, extracted and applied at 30g/L to maize plants at various growth stages to assess their insecticidal properties against common pests such as aphids, armyworms, and maize weevils while the control (Cypermethrin) was applied at 2.25ml per liter. The results of the study demonstrated that the application of Hyptissuaveolensextracts significantly reduced the population of insect pests compared to the control group. The extracts exhibited strong insecticidal properties, effectively repelling or eliminating a wide range of insect pests.
