In the light of the findings of the study, the researcher recommended that students should be aware of the importance of English syntactic structure in the process of EFL learning. Furthermore, teachers should teach English structure systematically and comprehensively and allow sufficient practice time, teachers should also focus on the overall structure of English relative clauses as a way of facilitating holistic development of English skills, in addition, understanding of the errors is helpful in the teaching and learning process since it enables both the teacher and students to identify the causes of the errors and find appropriate solutions towards improving the students’ learning process. Key words: Foreign language learning, English relative clauses, using relative clauses’ difficulties.
A facial recognition system is a technology capable of matching a human face from a digital image or a video frame against a database of faces. An essential aspect of facial recognition technologies is the dataset of faces used for training and testing. However, because most models are trained on mostly Caucasian faces, algorithmic accuracy on Caucasian faces tends to be higher than on African faces. This resulted in facial recognition bias and some unfavorable societal consequences such as false arrest and excessive government surveillance where people of color have been most affected by these consequences. Tribal marks are often neglected in facial recognition and can be used to improve the accuracy of the system. In this paper, we used a one-shot learning model to implement a facial recognition system for African tribal marks. We began by collecting datasets of people with tribal marks and then used Data Augmentation techniques to increase the size and balance of our dataset. An MTCNN model was used to detect and extract faces, and embedding points were generated using a pre-trained model. Using the F1 and MCC scores, we reported scores of 0.887 and 0.757 respectively. This research could be useful in tackling the racial disparity in facial recognition and ensuring that the database against which a face is matched accurately reflects local demographics.
Effective project leadership is considered a major ingredient for the performance of any organization operating in the ever dynamic and complex environment of the 21st century.

The plant Sterculia setigera (family: Sterculiaceae) is known by different indigenous cultural communities in Nigeria. It is a savannah tree, widespread in savannah areas of tropical Africa. The aim of this research is to carry out the phytochemical screening and antimicrobial activity of the leaf of sterculia setigera. The leaves of stercullia setigera was extracted with 70% methanol. The Phytochemical screening of the extract showed the presence of alkaloids, cardiac glycosides, saponins, phtobatannins, steroids, starch, resins. The Agar well diffusion method was used for the antimicrobial activity. The crude extract showed visible inhibitory effect when compared to the positive control. The crude extract of the leaves of stercullia setigera has zone of inhibitions of; 26 mm, 18 mm, 12 mm, 10 mm, for Staphylococcus aureus at 400 mg/ml, 200 mg/ml, 100 mg/ml, 50 mg/ml concentrations, 20 mm, 16 mm, 12 mm, 08mm, for Pseudomonas aeruginosa at 400 mg/ml, 200 mg/ml, 100 mg/ml, 50 mg/ml concentrations, 22 mm, 18.5 mm, 14.2 mm, 7.5 mm, for Escherichia coli at 400 mg/ml, 200 mg/ml, 100 mg/ml, 50 mg/ml concentrations and 23 mm, 20 mm, 16 mm, 10 mm, for Candida albican at 400 mg/ml, 200 mg/ml, 100 mg/ml, 50 mg/ml concentrations respectively. The mean zone of inhibition showed that stercullia setigera leaves exhibited activities against the test organisms. It was in this study that E. coli and S. aureus was more susceptible to the plant extracts compared to P. aeruginosa. The present study therefore offers a scientific basis for the traditional use of plant Sterculia setigera for the treatment of Mycobacterium tuberculosis, malaria, jaundice, measles, syphilis and leprosy. The evaluation of phytochemical and antibacterial screening of Sterculia setigera concluded that methanolic extract contain saponins, phtobatannins, resins, cardiac glycosides, alkaloids, steroids, starch. These constituents could be responsible for the inhibition of the test organism. The present study therefore offers a scientific justification for the traditional use of plant Sterculia setigera for the treatment of Mycobacterium tuberculosis, malaria, jaundice, measles, syphilis and leprosy. Further studies are necessary in order to clarify the properties of Sterculia setigera leaves to obtain information enough to provide validation for its medicinal use.

The study aspired to achieve the following objectives: i)to compare factors affecting reading culture among selected secondary school students in Kamonyi district; ii) to identify the factors that affect reading among non-boarding and boarding students at G.S Rosa Mystica and ESB Kamonyi; iii) to investigate the causes of the reading among non-boarding and boarding students from G.S Rosa Mystica and ESBK schools by investigating the factors of reading , the study was carried out in Kamonyi District, Gacurabwenge Sector at G.S ROSA MYSTICA and E.S Ste Bernadette using a qualitative research method. The research targeted a total number of 340,501 respondents. A non-exploratory mixed-method design was used in this study. Data was gathered through interviews, and questionnaires to answer the research questions regarding the factors affecting the reading among selected secondary schools and compare the causes of the poor reading among students to discover what motivates students to read. The respondents were the students, teachers, parents. The reading was considered as dependent variable (DV) whereas the factors affecting the reading in secondary schools were independent variables (IV). This study used a descriptive methodology with a data collection, interpretation and analysis approach with respect to mathematical, computational, and statistical aspects. The techniques used to perform this research were descriptive and analytic pursuant toto data collected. Based on the quantity of numeric data we performed our research. The collected data was analyzed and interpreted using Microsoft Excel and professional software. The findings show that school leadership and management affect reading, and the lack of reading facilities (books) affects reading. The research confirmed that family poverty are causes that affect reading like the lack of appropriate reading program at school; lack of school library, lack of motivation to read lack of reading time at home. Majority of the questions scored a mean between 3.00 and 3.50. Unanimously, respondents disagreed that non reading teachers affects reading. The findings demonstrated that active students in reading can perform lessons, excel in all subjects and have effective communication skills particularly in English. To measure the statistical relationship between the used variables, the Pearson relationship between factors causing and affecting the reading culture exhibits positivity (0.950), for G.S Rose Mystica and (0.952) ESB Kamonyi, implying that, the reading is influenced the outlined factors.

The study focused on the effect of project monitoring and evaluation practices on project success with a reference of the HIV prevention project implemented by ASOFERWA in Kamonyi district between 2018 and 2020. The study was done through descriptive research design that involved descriptive and inferential approach as mean of correlation analysis and linear regression analysis that helped to establish relationship of M&E components and project success. Through census inquiry 125 individuals were sampled comprised of ASOFERWA employees and stakeholders linked with surveyed project. Questionnaire, interview and focus group discussion were used to collect data. Statistical Package for Social Sciences (SPSS) was applied in statistical analysis. Regression analysis established that almost 59.7.3% is the contribution of monitoring and evaluation on project success of HIV prevention project implemented by ASOFERWA in Kamonyi district between 2018 and 2020. ANOVA results brought a positive F-value of 13.229 with a p-value of 0.000 which is less than alpha (0.01) showing a positive and significant effect of monitoring and evaluation on success of HIV prevention project implemented by ASOFERWA in Kamonyi district between 2018 and 2020. Therefore, according to the decision rule the null hypothesis suggesting that there is no significant effect of monitoring and evaluation practices on project success was rejected in favour of alternative hypothesis. However, during HIV prevention implemented with ASOFERWA some challenges and weakness encountered include inadequate staff to deliver effective monitoring and evaluation and to manage M&E process and data analysis, inadequate funds due to insufficient project budget along with lack of advanced technical advice for monitoring and evaluation. Even though HIV prevention project implemented by ASOFERWA, contributed to increase of knowledge towards HIV/AIDS, still women get HIV positive pregnant in Kamonyi district. The study recommended ASOFERWA to stress on continuous fundraising without waiting to finish current funding, to use more advanced and relevant in M&E for future projects and more programs to help mothers not transmitting HIV to child.

The results of the study regarding the third concerning the relationship between social media marketing and organizational visibility showed that the overal mean is 1.216 which implies that social media marketing affects oranisational performance and it is also supported by correlation results which showed that there is a positive and significant relationship between social media marketing and Business responsiveness (r=.940 and sig=.000), between social media marketing and business performance (r=.934 and sig=.000), and between social media marketing and awareness level increment (r=.883 and sig=.000) due to the fact that the calculated significance level is below 0.01; which shows that threre is a positive and significant relationship between social media marketing and organizational visibility in PSF. Therefore, the researcher would like to recommend to marketing team to keep improving performance through using digital marketing that puts into consideration customer lifetime value, increasing number of the customer to buy existing and new products, putting in place the system to monitor and control the newly acquired Business responsiveness through communication, increasing social media marketing by increasing Business responsiveness of the Private Sector Federation that enhance organisational visibility.
This work aims to analyze the link between the recovery of economic activity and the performance of money-creating banks in the DRC, following a banking landscape that has undergone profound changes over the past two decades. The study shows that liquidity is a key determinant of Congolese banks for both economic profitability and financial profitability. Thus, this liquidity ratio shows that it has a positive and statistically significant effect on the profitability of Congolese banks. Thus, Congolese banks display a profitable processing activity. The study also shows that the size of the bank, its relationship is positive both for economic profitability (ROA) and for financial profitability (ROE), then that it has a statistically significant effect for financial profitability and not significant for economic profitability; the effect of the equity ratio, while being negatively related to economic profitability (ROA) and financial profitability (ROE), is not significant. It suggests that the public authorities intensify economic growth and limit inflationary pressures in order to allow banks to take full advantage of the country's economic performance and to put in placeincentive mechanisms to enable the population to resume confidence in the banking sector such as deposit insurance.
