Published: January 2024

Penelitian ini bertujuan untuk menggambarkan persepsi siswa tentang penerapan Pembelajaran Berbasis Proyek (PjBL) di kelas Teaching English to Young Learners (TEYL). TEYL adalah mata kuliah wajib untuk mahasiswa tahun ketiga sebagai penciri jurusan Pendidikan Bahasa Inggris sebuah universitas swasta di Indonesia. Untuk menjawab pertanyaan penelitian tersebut, data diperoleh melalui angket dan observasi. Hasil temuan penelitian ini diharapkan dapat memberikan kontribusi terhadap body of knowledge penelitian tentang TEYL dan secara khusus memberikan wawasan lebih bagi para peneliti di TEYL. Penelitian ini menggunakan desain penelitian kualiitatif dan dilaksanakan di kelas TEYL dengan 32 mahasiswa sebagai responden. Angket digunakan untuk mengumpulkan data tentang persepsi mahasiswa terhadap implementasi PjBL dan lembar observasi digunakan untuk mengetahui keterlibatan mahasiswa di kelas. Kuesioner dibuat berdasarkan teori Robbins and Judge (2013). Data kemudian dianalisis secara tematik. Hasil penelitian menunjukkan bahwa mahasiswa mempersepsikan proyek secara netral untuk tiga aspek perciever, target dan situation. Para siswa tidak terlalu termotivasi dan terlibat dalam proyek karena tantangan Covid 19 terjadi dalam waktu bersamaan pada pelaksanaan penelitian. Mereka dipaksa untuk melaksanakan pembelajaran online dan melaksanakan proyek secara individu dengan pembimbingan secara luring yang kurang intensif.This research is aimed to portray the students’ perception of the implementation of PjBL in a Teaching English to Young Learners (TEYL) class. To answer the questions, the data are obtained through a questionnaire and observation. The findings of the research are expected to contribute to the body of knowledge of research on TEYL and specifically to give more insights to researchers in TEYL. Using qualitative research design, the study was implemented in a TEYL class with 32 students as the participants of English Education Department of Universitas Muria Kudus in the academic year 2019/2020. A questionnaire was used to collect the data and was analyzed thematically using percentage. The research reveals that the students perceived the project neutrally for three aspects of perceiver, target and situation. The observation shows that the students have limited access to their group members out of classroom discussion. In addition, the lecturer only gave minimum assistance before and after the completion of the project. During the project completion, either the lecturer and students or the students and the students seemed not connected. Further factors that might contribute to the success of PjBL should be taken into account, such as the teacher’s role as facilitator, the use of various technological learning media and effective communication between students and teacher and among students themselves.

Abstract
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) selectively induces apoptosis of sensitive cancer cells, including colorectal cancer (CRC). Due to its short biological half-life after intravenous administration and related clinical ineffectiveness, novel formulations of TRAIL need to be developed. Here we propose Lactococcus lactis bacteria as a vehicle for local delivery of human soluble TRAIL (hsTRAIL) in CRC. The use of common probiotics targeting guts as carriers for TRAIL could ensure its sustained release at the tumor site and extend the duration of its activity. We have already engineered hsTRAIL-secreting L.lactis bacteria and showed their effectiveness in elimination of human CRC cells in vitro and in vivo in a mouse subcutaneous model. Here, L.lactis(hsTRAIL+) were administered by gastric gavage to SCID mice with orthotopically developed HCT116 tumor in cecum, in monotherapy or in combination with metformin (MetF), already shown to enhance the hsTRAIL anti-tumor activity in subcutaneous CRC model. Oral administration of L.lactis(hsTRAIL+) resulted in significant progression of HCT116 tumors and shortening of the colon crypts. Secretion of hsTRAIL in the colon was accompanied by infiltration of the primary tumor with M2-macrophages, while MetF promoted transient colonization of the gut by L.lactis. Our study indicates that L.lactis bacteria after oral administration enable delivery of biologically active hsTRAIL to colon, however its potential therapeutic effect in CRC treatment is abolished by its pro-tumorigenic signalling, leading to the recruitment of M2-macrophages and tumor growth promotion.

Abstract
Primordial radionuclides are, among others, sources of radiation exposure to man. In this study, dust from some 24 nursery and primary schools in Ife Central and Ife East Local Government Areas (LGA) of Osun State were collected and analysed for 238U, 232Th, and 40K using CsI scintillation detector connected to a Universal Radiation Spectrum Analyser (URSA II) for spectrum analysis. From the specific activity concentrations of 238U, 232Th, and 40K, absorbed dose rates and radiological parameters were calculated. The mean activity concentrations of 238U, 232Th, and 40K in Bq/kg were found to be (45±2, 46±2), (56±5,60±5) and (669±76, 744±86) respectively for Ife Central and Ife East LGAs, however, the difference between the data sets from the two communities were not statistically significant. The total mean ± S.D (standard deviation) calculated over the whole study area were as follows; 238U= 45±11; 232Th=58±15 and 40K=702±196. The values of these radionuclides’ activities were higher than the world averages of 33, 45, and 420 for 238U, 232Th, and 40K respectively set by UNSCEAR. The mean absorbed dose rate in the air (in nGy/h) for Ife Central was 85±7 while for Ife East was 92±8. Both values were higher than the world average of 55 nGy/h. Also, the excess lifetime cancer risk was 1.66 × 10-3 for Ife Central and 1.8 × 10-3 for Ife East LGAs. Generally, Ife East LGA has higher activity concentrations than Ife Central LGA although the difference is not statistically significant.

Abstract
The present study aimed to determine bioaccessibility (BA) of polyphenols (PPs) and flavonoids (FLs) compounds of Ginger (Zingiber officinale) leaves extract after simulated gastrointestinal digestion (GID). One hundred grams of Z. officinale leaves (raw and dried) was extracted with 200 mL of distilled water. Determination of PPs and BA index were carried on the extract before digestion (BD) (undigested), post-intestinal digestion without enzymes (PI-DWOEs) and post-intestinal digestion with enzymes (PI-DWEs) using standard methods. The results showed significant decrease in proanthocyanidins (PCs) and anthocyanins (ACs) of dried and raw Z. officinale in PI-DWEs when compared to PCs and ACs level in BD. A total of nine major PPs compounds were detected in raw Z. officinale leaves in BD and PI-DWOEs, whereas eight PPs were detected in PI-DWEs. In PI-DWOEs, sinapinic acid (6.68 ng/mL) was the most prominent whereas p-coumaric (7.74 ng/mL) was the most protuberant in PI-DWEs. The concentration of total PPs were as follows; BD (41.39 ng/mL) > PI-DWEs (13.6 ng/mL) > PI-DWOEs (19.20 ng/mL). In conclusion, after the in vitro GID of the extract, a good BA index was observed, of which some PPs and FLs contents were near to 100%. However, the reason most PPs and FLs in the extract cannot be available or absorbed intact after digestion could be due to the fact that they undergo a series of reactions with intestinal enzymes. Additionally, not all polyphenols are absorbed equally well. Before it is feasible to predict how PPs will be assimilated by cells, they must first be bioaccessible.

Abstract
Despite the widespread use of omeprazole (OME), there are still concerns about its long-term safety and tolerability, especially with long-term or indiscriminate use. This study was designed to evaluate the effect of 90 days sub-chronic administration of OME on haematological, biochemical, antioxidant, reproductive and histopathological parameters in male and female rats. Forty-eight (48) Wistar rats of both sexes were divided into 4 groups of 6 male and 6 female animals each. Group I received 10 mL/kg normal saline, while Groups II – IV received 0.12 mg/kg, 0.57 mg/kg, 2.85 mg/kg of OME respectively for 90 days. At the end of 90 days, 5 mL blood sample was collected, and vital organs were harvested for relevant analyses. In this study, OME did not elicit any significant (P>0.05) change in the body weight or weight of vital organs, but elicited a significant (P<0.05) reduction in sperm count at the supratherapeutic dose (2.85 mg/kg). The supratherapeutic dose of OME produced significant increase in cholesterol (P<0.0001) and LDL (P<0.0001) in female rats. OME did not generally produce a significant change in haematological parameters. OME elicited a significant decrease in CAT (P<0.05) in female and combined animals. Additionally, histopathological presentations of vital organs were generally non-abnormal. From this study, it can be concluded that long term administration of OME is generally safe and tolerable, especially at lower doses. Findings from this study suggest that OME may potentially induce changes in sperm characteristics (in relation to male rats), hepatoxicity, hypercholesteremia, hyperlipidemia and thrombocytosis over a long duration, at higher doses and especially in female animals.

Published: January 2024

Abstract
The application of robotics continues to advance and lends itself to various disciplines. Previous work has shown how Markov decision processes can be integrated in an algorithm to handle pipeline inspection. This has been extended to building models and addressing the errors in the model from the data collected. This paper made use of data collected by simulated robots in a pipeline environment, to build an ensemble. Five models were explored and analysed viz: Linear model, Generalised linear model, K-nearest neighbour, Neural network, and Random Forests models. The models were used to explore the responses acquired from the pipeline corrosion data. The performance of each of the ensembles are evaluated based on the Root Mean Square Error (RMSE), Adjusted R2 and Mean Absolute Error. Model evaluation show that although the averaging ensemble has a better fit (34.56%) than the stacking ensembles (17.22% and 16.98% respectively) considered, it also has the higher RMSE,(81.90) than the stacking models ( 40.91 and 38.53 respectively) forcing the decision maker to make a trade-off between fit and precision.
Investigating the Impacts of Tropospheric Parameters on Received Signal Strength of the Mobile Communication System
Authors: Akinwole Bukola H. , Yussuff Abayomi I.O. 
Published: January 2024

Abstract
Radio communication systems are crucial for information transmission, but they face challenges like interference and fading, which significantly impact network efficiency. Understanding propagation-related issues is crucial for optimizing networks. This study examined the influence of tropospheric parameters on the Received Signal Strength (RSS) of the Globacom communication system in Rivers State. Four tropospheric variables (air temperature, relative humidity, atmospheric pressure, and wind speed) are collected from the River State University of Science and Technology (RSUST) Environmental and Climatic Observatory Program. The results of the correlation analysis indicated a direct linear correlation between air temperature and RSS. In contrast, wind speed displayed an indirect relationship, while the remaining parameters demonstrated an inverse linear relationship. Multiple linear regression (MLR) and multiple linear perceptron (MLP) models were developed to accurately predict the impacts of tropospheric parameters on RSS. A supervised-learning three-layered MLP feed-forward neural network was employed, consisting of 10 distinct MLP NN models. The Levenberg-Marquardt (LM) learning algorithm was used in training and validating the MLP NN models. The MLP 4-40-1 model showed an exceptional understanding of the non-linear relationship between the tropospheric parameters and RSS. The MLR model exhibited a weaker correlation coefficient of 0.2164, while the MLP demonstrated a stronger correlation coefficient of 0.7942. Additionally, the MLP 4-40-1 model outperformed the MLR model in terms of Root Mean Square Error (RMSE) and Mean Absolute Percentage Error (MAPE), achieving an accuracy of 0.2480 RMSE and 12.9963% MAPE, while the MLR model had 1.6880 RMSE and 27.3787% MAPE. These findings highlight the efficiency of the MLP 4-40-1 model in estimating the exact relationship between the tropospheric parameters and the signal strength of the mobile network in Rivers State. The study provides valuable insights into optimizing network design and emphasizes the significance of including tropospheric parameters in enhancing mobile communication performance.

Abstract
Phytochemicals that are naturally occurring in plants are known to be potentially bioactive, having anti-oxidative, antimicrobial and enzyme inhibiting potentials. This study investigated the antimicrobial, antioxidant and antidiabetic activities of the methanol and dichloromethane extracts of the leaf and stem Sorindeia warneckei. The plant extract showed the presence of saponins, flavonoids, terpenoids, tannins, glycosides, coumarins, steroids, alkaloids, anthraquinones and reducing sugars. The antioxidant potential was evaluated using DPPH radical scavenging assay while the antidiabetic activity was evaluated using an in-vitro α-amylase inhibitory assay. The DPPH free radical scavenging activity was expressed in % inhibition with L Ascorbic acid as standard showing IC50 0.69μg/ml with methanol extract while dichloromethane leaf extract having the highest activity at 0.45μg/ml. The α-amylase assay showed that the extracts exhibited potent alpha amylase inhibitory activity in a dose dependent manner with the leaf methanol extract having an IC50 of 2.33µg/L. The antimicrobial screening using the agar diffusion and agar dilution methods against the bacteria isolates Staphylococcus aureus, Salmonella typhirimurium, Escherichia coli and Streptococcus mutans and the fungal isolates Candida albicans, Aspergillus niger, Aspergillus flavus and Rhizopus oligosporus showed a good positive result. Preliminary investigation reveals that Sorindeia warneckei, contain bioactive compounds that possess promising pharmaceutical potentials that could be exploited.

Authors: David I. J. , Ikwuoche P. O. , Kolo R. L. 
Published: January 2024

Summary
This research fitted a discrete distribution for modeling count data. Specifically, Zero-Inflated Poisson (ZIP) regression was used to model plant protein consumption by 400 randomly sampled individuals in Wukari. The data was collected by questionnaire. The ZIP regression model was used based on its ability to model data with excess zeros present in the collected data. Variables considered and used for the analysis are Age, Body Mass Index, Blood Pressure, Occupation, Gender, Weight, Height, Body Reaction, and Consumption Class. The parameters of the ZIP model were estimated using the maximum likelihood estimation technique. The model was tested for Goodness of Fit (GoF) using deviance, scaled deviance, Pearson–χ
2 and scaled Pearson–χ
2 statistics. The results obtained showed that Age, Gender, and Reaction were significant at 5%, and the GoF tests revealed that the Zero-Inflated Poisson regression produces a good fit and is a good model for overcoming the overdispersion effect.
Fujiwara’s inequality for synchronous functions and its consequences
Authors: Otachel Zdzisław 
Published: January 2024

Summary
The theory of inequalities is an essential tool in all fields of the theoretical and practical sciences, especially in statistics and biometrics. Fujiwara’s inequality provides relationships between expected values of products of random variables. Special cases of this inequality include important classical inequalities such as the Cauchy–Schwarz and Chebyshev inequalities.
The purpose of this article is to prove Fujiwara’s inequality in abstract probability spaces with more general assumptions for random variables than those associated with monotonicity as found in the literature. This newly introduced property of random variables will be called synchronicity. As a consequence, we obtain inequalities originated by Chebyshev, Hardy–Littlewood–Pólya and Jensen–Mercer under new conditions.
The results are illustrated by some examples constructed for specific probability measures and specific random variables. In biometrics, the obtained inequalities can be used wherever there is a need to compare the characteristics of experimental data based on means or moments, and the data can be modeled using functions that are synchronous or convex.
