Authors: Szewczuk Katarzyna
Published: December 2024

Edukacja XXI wieku stawia przed nauczycielem wiele wyzwań. Umiejętność poradzenia sobie w dynamicznie zmieniającym się środowisku, nowe technologie, rozwijanie kompetencji przyszłości (w tym kompetencji miękkich), wrażliwość na problemy współczesnego świata to tylko niektóre z nich. Jednym ze sposobów poradzenia sobie z tymi wyzwaniami jest propozycja edukacji dla zrównoważonego rozwoju. Jej odpowiednia realizacja, co wymaga adekwatnego przygotowania nauczyciela do zawodu, może przyczynić się do budowania zrównoważonego społeczeństwa.Celem artykułu jest przedstawienie dwóch inicjatyw realizowanych w ramach projektu Kids Lab for Sustainability – wspólnoty uczącej się oraz kursu online, kierowanych m.in. do studentów kierunków nauczycielskich Uniwersytetu Ignatianum w Krakowie. Ich prezentacja koncentruje się na ukazaniu zaangażowania studenta w propozycję nabywania wiedzy oraz umiejętności praktycznych w temacie edukacji dla zrównoważonego rozwoju. Uczestnicząc w poszczególnych etapach projektu oraz realizując kurs online, studenci mieli możliwość poznania założeń edukacji opartej na tym nurcie, a także byli zachęcani do praktycznego testowania propozycji (scenariuszy/zasobów) zajęć, proponowania ich modyfikacji, własnych pomysłów czy autorskich rozwiązań. Propozycja tak zorganizowanej pracy spowodowała pozytywny odbiór i wysokie zaangażowanie studentów w przedstawiane przez członków projektu aktywności. Studenci doceniali zarówno atrakcyjność materiałów (scenariuszy/zasobów) opracowanych przez zespół realizujący projekt Kids Lab for Sustainability i zamieszczonych na jego stronie, jak i sposób przekazu wiedzy.

ABSTRACT
This research was aimed to determine the content of phenolic compounds, flavonoids, and condensed tannins in ethanol extracts obtained through soxhletation and reflux of mangosteen leaves, and to determine their effectiveness in inhibiting the α-amylase enzyme. The research was conducted through the stages of preparation, extraction, determination of total phenolic, flavonoid, and condensed tannin content, as well as determination of α-amylase enzyme inhibition activity. The highest yield was obtained from the ethanol extract produced by reflux for 4 hours (R4) (19.88%) and the lowest was obtained from the ethanol extract produced by Soxhletation for 2 hours (S2) (7.97%). The highest total phenolic and flavonoid content was found in the ethanol extract produced by Soxhletation for 8 hours (S8) (226.73 µg/mL and 266.76 µg/mL). The highest condensed tannin content was obtained in the ethanol extract produced by Soxhletation for 4 hours (S4) (24.36 µg/mL). The highest α-amylase enzyme inhibition activity was shown by the ethanol extract produced by Soxhletation for 4 hours (S4) 750 µg/mL (92.95%). It can be concluded that the ethanol extract of mangosteen leaves obtained through the Soxhletation process is more effective in inhibiting the α-amylase enzyme compared to that obtained through the reflux process.
Predicting medical drug usage intentions via SGD-based text classification model
Authors: Bağcı Daş Duygu
Published: December 2024

The effects of medical drugs and their usage purposes vary among individuals due to the chemical composition of drugs, side effects, genetics, etc. Even if those effects are to be discovered pharmacologically, they cannot be fully understood. Hence, it becomes essential to analyze the individuals’ reviews and experiences to unearth such effects and find out which other purposes drugs are used for, in addition to the target disease they are developed to cure. Text classification methods present various solutions to analyze those reviews effectively. Generally, these effects are investigated in terms of emotional analysis of medical drug usage experience as positive or negative. However, some drugs can be used for more than one specific treatment. For example, an antipsychotic drug can be used for both depression and anxiety or ADHD. Therefore, the effects of medical drug users and drug names to be associated with the review of the studies should be covered comprehensively. Based on this motivation, this study proposed a lightweight model for the prediction of medical drug usage intentions using text-based patient reviews. For this purpose, TF-IDF and bigram methods are used for text classification in the feature extraction step, then the Stochastic Gradient Descent (SGD) classifier is used for prediction and compared to other popular machine learning algorithms. Classification results indicate that the SGD and TF-IDF-Bigram approach effectively predicts drug usage intentions for medical purposes with an accuracy of 98.42%. Based on the outcomes, it is concluded that the findings of this study may be beneficial in pharmaceutics or medicine considering drug design, reducing side effects, health management, treatment adherence and process design, and personalized medicine.
Simulation of fuzzy logic and PI control methods on a bridgeless isolated SEPIC converter for electric vehicle chargers
Authors: Uğurluoğlu Alperen , Karaarslan Ahmet
Published: December 2024

Studies in literature and the increasing trend of electrification show that electric vehicles (EVs) will become more widespread in the future. However, the growing demand for EV chargers causes an overload on the grid. Furthermore, EV chargers generate power factor distortion and harmonics, which contaminate the grid and lower the quality of power. Therefore, power factor correction (PFC) is applied by EV chargers to mitigate the harmonics. As defined in the IEC 61000-3-2 standard, the total harmonic distortion (THD) shall be less than 5%. In this study, a better PFC operation is achieved with the proposed bridgeless isolated single ended primary inductor converter (BL SEPIC) topology as an EV charger instead of conventional converter topologies that have diode bridge rectifiers (DBR). Also, the study has better THD outputs as compared with the similar bridgeless (BL) topologies in literature thanks to the simulated control methods of the proportion-integration (PI) and fuzzy control. Moreover, these control methods are compared with each other in terms of THD suppression performance, stability, robustness, and computational effort. The results showed that the fuzzy controller has advantages of stability and robustness against the transient conditions, input voltages and load changes for THD suppression while the PI controller has better THD results only for steady state operation with nominal input voltage and full load conditions. The implemented PI and fuzzy controllers are simulated in a MATLAB Simulink environment.
Thermomechanical vibration response of nickel foam nanoplates
Authors: Eroğlu Mustafa
Published: December 2024

This article studies the buckling properties of nickel foam nanoplate. This research used nonlocal strain gradient elasticity and the new theory of sinusoidal higher-order deformation. After deriving the nanoplate's equations of motion from Hamilton's principle, the Navier technique was used to solve them. Two different kinds of foam models, uniform and symmetric, can be used to depict the nanoplate. Examining the nanoplate's dimensionless fundamental natural frequencies was the study's primary goal. The effects of temperature difference, nonlocal parameters, foam void ratio, and two different kinds of foam were considered in this investigation. In this context, the nanoplate's natural frequency decreases by 23.78% in the symmetric foam model and 51.5% in the uniform foam model as the foam void ratio increases. The research provides valuable insights for the development of nanoelectromechanical systems (NEMS), nanosensors, and transducers intended for high-temperature environments. By analyzing the impact of temperature and foam void ratio on nanoplate stability, the study informs material selection and structural design for applications where performance under thermal stress is critical, such as in aerospace and energy sectors.

Hydrogen as a renewable energy source is increasingly important in efforts to reduce carbon emissions and transition to clean energy. Many power plants are equipped with hydrogen plants that produce hydrogen gas continuously, but excess hydrogen is often disposed of when storage reaches maximum capacity. This study proposes the use of excess hydrogen to power fuel cells as a backup energy source in various important facilities, such as commercial centres, fitness, and health services. Hydrogen fuel cells offer the main advantage of zero-emission operation, making them an ideal solution for improving energy sustainability. By using previously discarded hydrogen, not only energy waste can be minimized, but it also opens new business opportunities in the sale and rental of fuel cell systems to consumers who care about their carbon footprint and clean energy. The hydrogen gas productivity at a power plant reaches 88.8 kg/day, and the potential excess hydrogen gas at a power plant reaches 48.84 kg/day. One kilogram of hydrogen gas can generate 15 to 20 kWh of electrical energy. The study also examines potential business models that focus on the utilization of hydrogen from renewable energy sources such as solar, hydro, and geothermal. In addition, the analysis shows that the application of fuel cells for backup energy systems in strategic locations can reduce dependence on conventional energy that generates emissions. The use of this technology has great potential to support green energy infrastructure in Indonesia and is in line with global initiatives towards reducing carbon emissions. With the cost of hydrogen production getting lower and the growing awareness of the importance of clean energy, this approach is expected to play a significant role in achieving sustainable energy targets.

Authors: Chiusaroli Diletta
Published: December 2024

For a healthy cognitive and emotional development of their children, it is essential that parents exercise a parental responsiveness, oriented to respond adequately to their educational needs. Unfortunately, parental function can be compromised by social and existential fragility, as in the case of vulnerable mothers such as migrant mothers, prisoners, and victims of violence. The autobiographical method is an effective tool for formation that allows us to reimagine life events and reconstruct existential fragility, trigger resilience processes, and involve mothers and children in reactive parental responsiveness dynamics.

The objective of this study was to analyze the profile of Paralympic canoeing athletes with resilience and perception of performance, as well as to compare the variables depending on gender and medal-winning and non-medal-winning athletes. This is a descriptive and quantitative study with a cross-sectional design, in which 40 athletes of both sexes with physical-motor disabilities and active in the 2023 Brazilian Paralympic canoeing championship participated. The instruments used were: anamnesis; Resilience Scale in Sport and the Sport Performance Perception Questionnaire. Descriptive analyzes were carried out to characterize the sample, as well as Shapiro-Wilk and Mann-Whitney linear inferential tests and non-linear Bayesian network analysis for comparisons. The majority of the sample was made up of: male athletes; athletes with paraplegia; and competitors from both disciplines (KL and VL). Of the 40 athletes, 22 were medalists in the 2023 Brazilian championship. The results indicated that women are more sensitive to the variables of resilience and perception of performance, but men showed higher levels of perception. When athletes win a medal, they tend to perceive themselves better and be more resilient. It is concluded that the way they perceive their performance and resilience directly influences their performance, and it is important that targeted psychological interventions are carried out. Therefore, profiling the athletes is advantageous in terms of gathering more information and understanding the entire environment and factors that can influence the final result of the competition, where any detail can make the difference between victory and defeat.

Phycoremediation Potentials of Chlorella vulgaris in Degradation of Crude Oil Spill
Authors: Chinwe Aneke Jacinta
Published: December 2024

The contamination of aquatic ecosystems by crude oil spills is a pervasive issue in Nigeria's oil-producing regions, where waterways are frequently polluted with hydrocarbons, a primary constituent of crude oil. This study examined the phycoremediation capabilities of Chlorella vulgaris using established protocols. The algae isolated from freshwater samples were confirmed to be C. vulgaris. The results of the screening test revealed the organism's capacity to degrade heavy crude oil, as evidenced by varying levels of turbidity in the mineral salts-oil medium. Over a 47-day period, the pH of the mineral salts-oil medium decreased progressively, transitioning from neutral to acidic levels, ultimately reaching a pH of 4.1. Conversely, the absorbance of the medium increased over the same period, indicating C. vulgaris growth. Notably, the residual oil content in the mineral salts-crude oil medium decreased substantially, with a degradation rate of 80%. This study demonstrates the potential of C. vulgaris in phycoremediation of crude oil spills in Nigeria.

Published: December 2024

Calliandra portoricensis (CP) is used in ethnomedicine to manage breast inflammation. We investigated the anti-mammary tumour effects of fraction from CP in rat model of mammary tumorigenesis induced with N methyl N nitrosourea (NMU) and benzo (a)pyrene (BaP) and MCF-7 cells. In vivo, thirty-two female Wistar rats were assigned into four equal groups: Group 1 (control), group 2 received [NMU (50 mg/kg) +BaP (50 mg/kg)], group 3 received [NMU (50 mg/kg) +BaP (50 mg/kg) + CP (100 mg/kg)] and group 4 received [NMU (50 mg/kg) +BaP (50 mg/kg) + vincristine (VIN) (500 μg/kg)]. The NMU and BaP was injected intraperitoneally to rats at age 7, 10 and 13 weeks for twelve weeks. Thereafter, CP (orally) and vincristine (i.p) was administered for two weeks. In vitro, CP and VIN concentration-dependently inhibited the growth of MCF-7 cells by over 80% at 100 µg/mL. The CP and VIN elevated Bax by 4.2 and 1.5 folds, and decreased myeloperoxidase by 75% and 82%, respectively, while CP alone decreased interleukin-1β by 34% in vitro. In vivo, [NMU+BaP] increased weight and organo somatic weight of mammary gland by 3 and 2.9 folds; total bilirubin, nitric oxide and malondialdehyde by 23%, 51% and 52%, respectively. In [NMU+BaP] rats, weak expression of caspase-3, Bax, and strong expression of iNOS and NF-kB activities were observed, with histological alteration. The GC-MS fingerprint of CP fraction revealed the presence of hexadecanoic acid methyl ester as the most abundant constituent. Treatment with CP ameliorates mammary tumour through mechanisms that involve anti-inflammatory and pro-apoptotic reactions.

Background: Malaria continues to be a significant public health concern, particularly in sub-Saharan Africa and other regions with high endemicity. Despite ongoing efforts to control the disease, the malaria parasite remains a global health issue, presenting persistent challenges for individuals and healthcare systems in affected areas. Methods: This study investigated the distribution, prevalence, and molecular characteristics of Plasmodium falciparum among febrile patients in various healthcare facilities within the Federal Capital Territory (FCT), Nigeria. A combination of retrospective and cross-sectional designs was employed to analyse 428 blood samples collected from febrile patients across selected government hospitals. Malaria parasitaemia was detected through Giemsa-stained thick and thin blood smears, with parasite density calculated per 200 leukocytes. RDT-prevalence wax determined using a rapid lateral flow. Result: A total of 428 individuals participated in the study, comprising 49.0% males (n=210) and 50.9% females (n=218), with no statistically significant difference in gender distribution (p>0.05). The age distribution showed that participants aged ≥41 years represented the largest group at 34.3% (n=147), while those aged <10 years accounted for 14.0% (n=60), 11–20 years for 16.1% (n=69), 21–30 years for 19.2% (n=82), and 31–40 years for 16.4% (n=70). Microscopic examination revealed a malaria infection rate of 32% (n=137) among participants, with the highest prevalence in those aged <10 years (33.6%, n=46) and the lowest in the 31–40 age group (8.8%, n=12). Gender-based analysis indicated a higher prevalence in males (52.6%) compared to females (47.4%). Facility-based prevalence was significantly higher in Wuse (30.0%, n=41) compared to other locations, with Zuba showing the lowest prevalence (8.0%, n=11). Rapid Diagnostic Test (RDT) results indicated a prevalence of 20.1%, with Wuse again exhibiting the highest rate at 38.6% (n=27/70). Age-related RDT prevalence showed the highest seroprevalence in the <10 years age group (65.0%, n=39/60), followed by 11–20 years (24.6%, n=17/69), 21–30 years (12.3%, n=10/81), and ≥41 years (8.8%, n=13/147). Conclusion: The findings reveal a slight predominance of females over males, indicating that women may be more inclined to seek medical attention for malaria-related symptoms. The malaria prevalence rate of 32.0% underscores the urgent need for effective strategies to combat the disease.

Published: December 2024

Background: End-stage heart failure patients awaiting heart transplant often require Ventricular Assisted Devices (VAD) to support systemic and pulmonary circulation and to improve ventricular function, symptoms, and Health-Related Quality of Life (HRQoL). This study evaluates the health-related quality of life in patients with VAD and was conducted at the Cardio Ventricular Assisted Devices Clinic at King Faisal Specialist Hospital and Research Centre, Riyadh. Methods: This retrospective cohort study design included all eligible VAD patients who were still attending the cardio ventricular assisted devices clinic at KFSHRC, Riyadh. Each study participant was assigned a detailed questionnaire to assess and evaluate HRQoL outcomes measured in physical limitations, emotional stress, sexual activity, and social function from the date of device insertion to the time of data collection. Data were analyzed using the Statistical Package for Social Studies (SPSS 22; IBM Corp., New York, NY, USA). Results: Between February 2016 until June 2020, 26 patients were eligible for the study. The patients' support scores were moderate to high, indicating a positive effect on their HRQoL, with a mean score of 57.69 in emotional activity, a mean score of 34.07 in physical activity, and a mean score of 83.17 in social activity. The study's results show that the level of HRQoL varies among patients with VADs. Conclusion: Participating patients with VAD reported excellent health-related quality of life in all domains, with moderate to high support scores indicating a positive effect on their HRQoL. There is currently a lack of study on HRQoL in patients with VADs in Saudi Arabia. Therefore, this study may provide a baseline understanding of current challenges in the care of heart failure patients with VAD awaiting a heart transplant.

Female genital mutilation (FGM) remains a deeply rooted cultural practice with far-reaching consequences for the health, dignity, and rights of women worldwide. The study assessed the perception and knowledge of female genital mutilation among indigenous childbearing women in the Awka-South Local Government Area in Anambra State, Nigeria. The objectives of the study were to assess the level of knowledge and the level of perception of indigenous childbearing women in Awka, South L.G.A. of Anambra State towards female genital mutilation. The hypotheses were that there is no significant association between the level of knowledge and the level of perception of indigenous childbearing women in Awka-South L.G.A. of Anambra State towards female genital mutilation and that parity of indigenous childbearing women in Awka-South L.G.A. is not significantly associated with their perception. A cross-sectional, descriptive survey design was adopted for the study. The sample size was 437 indigenous childbearing women, and a multistage sampling technique was used. The instrument for data collection was a questionnaire. The reliability test indicated 0.72. The data obtained were analyzed using the statistical package for social sciences (SPSS); descriptive statistics, frequency, percentage, and mean were used to analyze research questions, and inferential statistics, chi-square, were used to test hypotheses at the 0.05 level of significance. The data were presented in tables for clarity. The findings of the study revealed that the majority, 77.2%, had a negative perception of FGM, and the majority, 64.0%, of the respondents had poor knowledge of FGM. There was no significant association between the level of knowledge and the level of perception of FGM among indigenous childbearing women, with p-value = 0.094, and the parity of indigenous childbearing women is not significantly associated with their level of perception of FGM with p-value = 0.431. In conclusion, indigenous childbearing women showed negative perceptions towards FGM, and indigenous childbearing women had poor knowledge of FG. It is recommended that healthcare providers, community organizations, and government agencies implement comprehensive education programs targeting indigenous childbearing women to improve their knowledge and understanding of FGM.

Kepatuhan (adherence) adalah minum obat sesuai dosis, tidak pernah lupa, tepat waktu, dan tidak pernah putus. Kepatuhan dalam meminum Antiretroviral merupakan faktor terpenting dalam menekan jumlah virus HIV dalam tubuh manusia.Kepatuhan minum obat ARV <80% merupakan suatu prediktor bagi kegagalan pengobatan HIV. WHO merekomendasikan dolutegravir sebagai terapi yang lebih dianjurkan sebagai terapi lini pertama ataupun terapi lini kedua pada pasien HIV yang sebelumnya gagal dengan pengobatan regimen tanpa dolutegravir. Penelitian ini bertujuan untuk menganalisis dan evaluasi kepatuhan pasien pengguna terapi Kombinasi Dosis Tetap (KDT) TLD di salah satu  puskesmas di Kota Bandung  serta faktor-faktor yang mempengaruhi kepatuhan pengobatan. Hal ini untuk meningkatkan keberhasilan terapi KDT TLD bagi pasien HIV positif di puskesmas. Jenis Penelitian ini observasional analitik dengan pendekatan menggunakan desain cross sectional. Pengumpulan data dilakukan secara retrospektif menggunakan data sekunder berupa catatan rekam medis, data Sistem Informasi HIV AIDS (SIHA) Kemenkes serta laporan pill count penggunaan obat. Dari 161 orang populasi yang memenuhi kriteria inklusi, sebanyak 143 orang (88,82%) pasien yang menggunakan terapi KDT TLD patuh dan 18 orang (11,18%) tidak patuh terhadap pengobatan ARV KDT TLD yang sedang dijalaninya. Analisis Faktor-Faktor yang mempengaruhi kepatuhan pengobatan KLD TLD dengan uji chi square dan stepwise menunjukan bahwa jenis kelamin dengan p-value = 0,000 mempunyai pengaruh yang signifikan terhadap kepatuhan pengobatan pasien, begitupun dengan usia p-value= 0,000. Hal ini menunjukan bahwa variabel jenis kelamin dan usia pasien mempengaruhi secara signifikan terhadap kepatuhan pengobatan pasien penerima terapi KDT TLD.

Penelitian ini bertujuan untuk mengeksplorasi kerangka hukum terkait Artificial Intelligence (AI) dalam aspek penyalahgunaan Deepfake Technology di Indonesia dan menganalisis potensi kriminalisasi atas penyalahgunaan tersebut melalui pendekatan Economic Analysis of Law. Menggunakan metode penelitian yuridis-normatif, studi ini mengkaji norma-norma hukum baik di dalam maupun di luar sistem hukum Indonesia, dengan fokus pada bagaimana faktor ekonomi dapat mempengaruhi kebijakan hukum. Penelitian ini menemukan bahwa kerangka hukum saat ini belum memiliki regulasi khusus yang mengatur penyalahgunaan Deepfake Technology, sehingga menimbulkan ketidakpastian hukum dan melemahkan kepercayaan masyarakat terhadap penegakan hukum. Studi ini menyarankan perlunya regulasi yang lebih rinci untuk menjamin kepastian hukum, serta penggunaan analisis ekonomi sebagai panduan dalam merumuskan sanksi yang efektif dan efisien untuk kejahatan terkait Deepfake. Implikasi dari pendekatan ini menekankan pentingnya mencapai keadilan, kepastian hukum, dan kemanfaatan hukum dalam menangani kejahatan siber.
