Published: May 2024

The article reviews modern information sources, in particular, reference databases and open access journals, the publications of which raise the issue of changes in the financial behavior of households in modern conditions, in particular, under the influence of digitalization. An analysis of the publication activity of foreign and domestic scientists regarding the disclosure of the problems of the transformation of the financial behavior of households for the period from 1975 to 2024 was carried out using the tools of scientometric analysis, implemented on the basis of the Web of Science, ScienceDirect and Google Scholar search engine platforms, by means of a special query using the term "household financial behavior" in titles, abstracts and keywords of publications. The dominant directions of disclosure of this topic by leading foreign scientists are highlighted. With the help of modern visualization programs, a bibliometric map of publications on the topic "transformation of the financial behavior of households in conditions of digitalization" was generated and four main clusters of concentration of scientific publications were formed, which characterize the main directions and trends in the research of this issue. Changes that appear in scientific publications of different countries and time periods are characterized, in particular, regarding the interpretation of the essence of the concept of household financial behavior and the main content that was invested in it. Trends in the financial behavior of modern households under the influence of digitalization technologies are considered. The impact of digital and financial literacy on the financial behavior of a digitalized household has been revealed. A high synchronous level of popularity among users worldwide for the search queries "digitalization" and "household" has been proven in the "Finance" category among Ukrainian users in the period 2019–2024 using the Google Trends service. In addition, the study of scientific trends among the mass of publications of foreign and domestic scientists, available thanks to modern electronic informational full-text, abstract databases and search systems, made it possible to predict the main directions for further research on this topic.

Authors: Nik Hassan Nik Mawar Hanifah , Talib Othman , Muhamad Mohd Mokhtar , Kamarudin Nurzatulshima
Published: May 2024

Teaching Organic Chemistry has always been viewed as difficult to teach, where learners are frequently repelled by the topic's high level of complexity, which appears to discriminate against the subject. Over the years, changes have been made from textbook-driven curriculum to activity-based learning for continuing meaningful learning provided in the Organic Chemistry classroom. This study aims to map the literature on teaching and learning strategies of Organic Reaction Mechanism (ORM) to be incorporated into a proposed module (ORM Module) between the year 2012 up to 2021. A computer-assisted literature search using Scopus, Google Scholar, EBSCOhost, and ProQuest was performed. Additionally, Arksey and O'Malley's (2005) five-stage framework guided the scoping review approach. The data extracted were respected to study characteristics, inclusion, and exclusion criteria of “organic reaction mechanisms” OR “mechanisms of reactions” keywords. Out of 784 records found in four databases, only 55 were suitable for full-text review, and 17 studies were finally included. Five key strategies for teaching ORM were identified: electron-pushing formalism (EPF), patterns of reactivity, technology integration, problem-solving, and self-regulated learning (SRL), along with six related teaching and learning activities. The findings of this study can be utilised for future development of the ORM Module. Further studies are recommended to investigate the interconnectedness of Organic Chemistry and other research areas.

Published: May 2024

The purpose of this study was to examine the effects of two lipid sources dosages on the digestive enzymes activity and growth of Kelabau (Osteochilus melanopleurus). In this study, there were five treatments and three replicates in a completely randomised design (CRD). In this investigation, the following dosage ratios of fish oil and corn oil were used as treatments: A (100%:0%), B (75%: 25%), C (50%:50%), D (25%:75%), and E (0%:100%). The experimental fish had initial average length of 5–6 cm and weight of 2.8–3.6 g. Fish were reared for 45 days in plastic tanks measuring 34.3 cm x 38 cm x 31.5 cm using a recirculation system. Each tank was filled with 25 liters of water and the fish stocking density was 20 fish/tank. Fish are fed twice daily on an at-satiation basis, in the morning and the evening. Data analysis was carried out using the analysis of variance (Anova) with a confidence level of 95% and continued with the Duncan Multiple Range Test (DMRT). The findings demonstrated that the activity of digestive enzymes (amylase, lipase, and protease) was significantly (P<0.05) impacted by the differences in the content of the two lipid sources, with an increase in the percentage of corn oil causing an increase in the activity of all digestive enzymes. Conversely, neither growth nor specific growth rate were significantly affected (P>0.05) by the variation in the percentage of the two lipid sources. But in contrast to the other treatments, treatment A resulted in more growth. The reason for this could be because the ingredients were adequate to meet the fatty acid requirements for Kelabau fish growth, therefore the fatty acid addition was no longer necessary.

Taxila intersection is facing severe traffic issues includingcongestion, delays, increased travel times and inadequate infrastructure. The aim of the study is to highlight the real problems at Taxila intersection related to road users, vehicles and road infrastructure. Traffic data was collected during peak hours through traffic observing video cameras at the unsignalized intersection. Subsequently, traffic violation measurements and their comparisons between morning and evening peak hours, as well as between weekend and week days were developed. The study also identifies the involvement in traffic violations by different drivers, age groups and vehicle types. Comparing morning and evening peak hours reveals variations in traffic patterns and congestion levels throughout the day, helping to create customized plans. Similarly, investigating disparities between weekends and weekdays uncovers unique factors influencing traffic conditions on different days. Results showed that highest percentage of violations at the intersection resulted from 'illegal crossing of road by pedestrian' followed by 'illegal parking' at the intersection. While the lowest percentage of violation observed was 'wrong way driving' at the intersection. In conclusion, this research provides a comprehensive understanding of the traffic issues at the Taxila intersection and offers evidence-based strategies to improve traffic flow, mitigate congestion, and enhance road safety in the area.

Published: May 2024

Wind tunnel tests are costly and time-consuming, and the accuracy of the tests is limited by the size of the tunnel, to solve this problem, researchers use computational fluid dynamics (CFD) to conduct wind tunnel experiments using a computer because it is less timely and less costly. Computerized testing of drone's models using wind tunnel experiment simulation in computational fluid dynamic (CFD) software requires knowledge of the most suitable turbulence model for this drone. In this paper ANSYS fluent program has been used to test four most common turbulence models for use (Spalart-Allmaras, K-Epsilon, K-Omega and Reynolds stress) and laminar flow on the ScanEagle drone model (an aerial reconnaissance drone used in military and intelligence operations) and calculated their effect on aerodynamic parameters In terms of accuracy and time to solution, concluded that the best turbulence model in terms of balancing accuracy and the time taken for the calculation is K-Omega model.

Introduction: Early menarche is increasing throughout the world, including in Indonesia. The average age of early menarche in Indonesia is less than 10 years based on the results of Riset Kesehatan Dasar or Basic Health Research 2013. Early menarche can cause stress, cardiovascular disease, and the risk of breast cancer. Early menarche can be influenced by various factors, one of which is nutritional status which can be assessed by body mass index.Objective: To determine the relationship between Body Mass Index and Menarche Age in elementary school “X” in Krian.Method: This study used a cross-sectional research design, conducted on a population of elementary school children in grades IV-VI aged 9-12 years at primary school “X” in Krian with the inclusion criteria being School Health Unit (Unit Kesehatan Sekolah or UKS) data and the exclusion criteria being having chronic diseases. Data analysis was carried out using the Spearman Correlation test.Results: 49 samples were obtained consisting of 7 people in class IV, 14 people in class V, and 28 people in class VI. From the sample, 8 children had a low BMI (16.3%), 30 children had a normal BMI (61.3%), and 11 children had a high BMI (22.5%). Meanwhile, for early menarche 6 people (12.2%), normal menarche 43 people (87.8%), and no late menarche (0%) obtained a p-value = 0.616 (p>0.05). The percentage of early menarche in obese BMIs is higher than in other BMIs with a percentage of 6.1%.Conclusion: There is no significant correlation between body mass index and age at menarche due to the small number of samples.

The great hammerhead shark Sphyrna mokarran and the scalloped hammerhead shark S. lewini are marine top predators with global distributions. However, limited information is available on the trophic ecology of hammerhead sharks in the Indian Ocean. In this study, we measured stable nitrogen and carbon isotopes in the muscle tissues of neonates and juveniles of S. mokarran and S. lewini from the waters of the western Arabian Gulf. In general, values of δ15N were lower in S. mokarran (10.8-18.7‰) than in S. lewini (12.2-18.7‰), indicating a reliance on food sources with low nitrogen values. Isotopic niche similarities were observed between female and male S. mokarran. We further observed considerable ontogenetic changes in the δ15N values of both S. mokarran and S. lewini neonates (a reduction from 19 to 12‰), reflecting the maternal effect. The effects of total length and sex on the nitrogen and stable isotope values were nonsignificant in S. mokarran juveniles. The western Arabian Gulf likely serves as a key feeding ground for both the neonates and the juveniles of S. mokarran. By contrast, S. lewini appears to have a low level of reliance on this region.
Seasonality influences the effect of warming on kelp photosynthesis
Authors: Franke K , Bartsch I , Karsten U , Graiff A
Published: May 2024

The consequences of a year-round warming scenario on the photosynthetic performance of kelp species are unknown. In times of global warming, fundamental photosynthesis data are important due to the high temperature dependence. Seasonal photosynthetic performance was quantified in the kelp Laminaria hyperborea sampled along a depth gradient (2, 4 and 6 m below mean low water spring tide) at the island of Helgoland (North Sea, Germany). Blade discs were cultivated at in situ irradiances and temperatures (spring: 7°C; summer: 16°C; autumn: 14°C; winter: 6°C) and in parallel under warming scenarios (+4°C) for 3 d. The results highlighted that seasonality and collection depth had a stronger effect on oxygen formation (photosynthesis versus irradiance curve) and pigmentation than short-term warming, as there is a stronger correlation with changing irradiance levels than with temperature. Photosynthesis was highest in spring and summer, with small impacts of warming, indicating a high resilience to short-term temperature increases. In summer, algae exhibited reduced maximum quantum yields (Fv/Fm) at sub-lethal temperatures (20°C), pointing to a moderate stress response. Photosynthetic acclimation along the depth gradient was intensified by short-term warming, reflected in a stronger decrease in Pmax and chlorophyll content. Overall, the influence of short-term warming on the depth acclimation varied seasonally, underlining the importance of considering the season. In conclusion, L. hyperborea revealed distinct seasonal photosynthetic response patterns and a high photoacclimation potential at different depths. Therefore, seasonal and depth effects need to be considered when predicting the effects of warming on kelp primary production.

For calcifying organisms such as bivalves, short-term exposure to increased ocean acidification (OA; elevated pCO2) may reduce growth rate, increase mortality, and disrupt shell formation. A growing body of research suggests that clearance rates and what particles bivalves select may change under high pCO2 exposure; however, these experiments are acute, ranging from days to weeks. The effects of food supply on bivalves under long-term OA exposure remain incompletely understood. In this study, juvenile northern bay scallops Argopecten irradians (Lamarck) that had been reared since 4 h post-fertilization under one of 2 OA conditions (∼500-600 or ∼750-850 µatm pCO2; ∼1.37-1.5 or ∼1.0-1.2 Ωaragonite), were subjected to 2 food levels for 42 d (low food: ∼400, high food: ∼1400 chlorophyll cells ml-1). Standard metabolic rate (SMR) and clearance rate (CR) were measured on Day 0, and SMR, CR, growth, and survivorship were measured at 14 and 42 days of exposure to 2 food levels for each of the OA treatments. Juveniles under food scarcity had reduced survivorship and growth independent of OA treatment. We found no effect of OA treatment or an OA × food interaction for these metrics. There was only a food-level effect for SMR and no OA treatment effect; however, there was an interaction between food and OA for CR. Under elevated pCO2 concentrations, scallops cleared Chaetoceros neogracile (strain Chaet-B) over Tetraselmis chui (strain PLY429) and natural seston. Altogether, these data suggest that tolerance to OA mediated by food may depend on food quality or other characteristics that influence particle selection under short-term experimental challenges.

Destructive fishing activities are a threat to the sustainability of fishery resources and harm fish stocks as well as environmental ecosystems. Comprehensive regulations are needed to cope with destructive fishing and ensure the regulations will be implemented well and appropriately. Using a qualitative approach, this study aims to scrutinize the implementation of policies issued by the central government in the regions, including laws and other national regulations related to coping with destructive fishing. North Maluku Province is the focus of the study to identify the implementation of national regulations in the region. In addition, this study also identifies the roles of maritime law enforcement agencies involved in efforts to supervise and implement national policies related to overcoming and preventing destructive fishing. The results reveal that existing laws are insufficient to cope with the destructive fishing criminal act. So far, eight actors have roles in the prevention and coping of destructive fishing activities, consisting of elements of maritime law enforcement agencies such as the Police, Indonesian Navy, Indonesian Coast Guard, and Directorate General of PSDKP, as well as civil or community elements such as the PWP3K Special Police, Forestry Police, Department of Marine Affairs and Fisheries, and Monitoring Community Supervisory Groups (Pokmaswas).

The shark is an important cartilaginous fish species in the Northeastern Mediterranean and has occupied a wide range of areas. They are landed for different kinds of reasons but mostly as by catch. Sharks have a great proportion of livers that are generally not used. The livers may have potential usage for different materials e.g., fish meal, food ingredients, and fish oil materials. Therefore, they should be used, not wasted. Determining its macro element and microelement composition could be beneficial for any raw material. According to this current study’s data, Cd and Pb levels were detected only in Fall. The Cr levels in the livers were not detected all year long. The amounts of the Cu, Mn, and Zn in the livers of common sharks all year long did not exceed 1 mg/kg, 1 mg/kg, and 2.4 mg/kg respectively. The livers contained high levels of Fe which differed from season to season. The difference in Fe amounts was found to be statistically significant between seasons (P>0.05). Even though changes were observed in the levels of microelements in the livers of common sharks in this study, there were no statistically significant changes except for Zn and Fe. There should be more testing to support the result suggested. Results of this study showed that the predominant macro minerals were Na and P for sharks in fall and spring (3968 and 3710 mg/kg, respectively throughout the year).

EFFECTIVENESS OF EFFLEURAGE BACK MASSAGE AND SLOW DEEP BREATHING ON VITAL SIGNS IN HYPERTENSION PATIENTS
Authors: Sepdianto Tri Cahyo
Published: May 2024

There are quite a lot of hypertension sufferers in middle age in society and are easy to detect. Controlling hypertension requires lifelong medication and non-pharmacological measures. To reduce the side effects of treatment, non-pharmacological measures are needed, namely effleurage back massage and slow deep breathing. This study aimed to assess the effectiveness of effleurage back massage and slow deep breathing on vital signs, oxygen saturation, and anxiety in primary hypertension sufferers aged 45 - 54 years. The method in this research uses a quasi–experimental design with a non-randomized pretest–posttest control group design approach. The sample for this study was primary hypertension sufferers aged 45 - 54 years who received routine treatment at the Health UPTD in the Blitar City area, totaling 101 sufferers (51 in the treatment group, 50 in the control group). Inclusion criteria for patients were having systolic blood pressure of 140 – 180 mmHg and diastolic 90 – 100 mmHg, receiving a maximum of 2 standard antihypertensive treatments and not smoking. Analysis used descriptive and t-tests. The results of this study showed that after effleurage back massage and slow deep breathing, there was a decrease in systolic blood pressure of 16.37 mmHg, diastolic blood pressure of 10.39 mmHg, pulse of 3.53 times/minute and respiration of 0.73 times per minute. Effleurage back massage and slow deep breathing are effective if done regularly and require a massage break after the sixth appointment.

The bacterial wilt pathogen Ralstonia pseudosolanacearum (Rps) colonizes plant xylem vessels and blocks the flow of xylem sap by its biofilm (comprising of bacterial cells and extracellular material), resulting in devastating wilt disease across many economically important host plants including tomatoes. The technical challenges of imaging the xylem environment, along with the use of artificial cell culture plates and media in existing in vitro systems, limit the understanding of Rps biofilm formation and its infection dynamics. In this study, we designed and built a microfluidic system that mimicked the physical and chemical conditions of the tomato xylem vessels, and allowed us to dissect Rps responses to different xylem-like conditions. The system, incorporating functional surface coatings of carboxymethyl cellulose-dopamine, provided a bioactive environment that significantly enhanced Rps attachment and biofilm formation in the presence of tomato xylem sap. Using computational approaches, we confirmed that Rps experienced linear increasing drag forces in xylem-mimicking channels at higher flow rates. Consistently, attachment and biofilm assays conducted in our microfluidic system revealed that both seeding time and flow rates were critical for bacterial adhesion to surface and biofilm formation inside the channels. These findings provided insights into the Rps attachment and biofilm formation processes, contributing to a better understanding of plant-pathogen interactions during wilt disease development.

This study introduces newly discovered chrysin derivatives that show potential as candidate molecules for treating inflammatory bowel disease (IBD). Compound 4b, among the synthesized compounds, displayed significant inhibitory effects on monocyte adhesion to colon epithelium induced by TNF-α, with an IC50 value of 4.71 μM. Further mechanistic studies demonstrated that 4b inhibits the production of reactive oxygen species (ROS) and downregulates the expression of ICAM-1 and MCP-1, key molecules involved in monocyte-epithelial adhesion, as well as the transcriptional activity of NF-κB. In vivo experiments have shown that compound 4b exhibits a dose-dependent inhibition of 2, 4, 6-trinitrobenzenesulfonic acid (TNBS)-induced colitis in rats, thereby validating its effectiveness as a colitis inhibitor in animal models. These results indicate that 4b shows considerable promise as a therapeutic agent for managing IBD.
