Abstract INTRODUCTION: Dental caries is a major global issue that has been connected to a number of systemic issues, necessitating multidisciplinary investigation. Examining dental degradation in conjunction with Helicobacter pylori infection provides a unique perspective on gut and oral health in Tripoli, Libya. Previously linked to peptic ulcers and chronic gastritis, H. pylori has recently been linked to tooth health. This change in viewpoint is crucial because there was no discernible link between the infection and chronic illnesses like diabetes, hypertension, or even smoking, indicating the necessity for measures to raise awareness of good oral hygiene among afflicted individuals. The prevalence of H. pylori was clearly linked to declining dental health when examining Decayed, Missing, and Filled Teeth (DMFT) scores; this relationship was particularly evident in older participants and those with poor oral hygiene. METHODS AND MATERIALS: a cross-sectional design was used, 135 randomly selected participants to ensure that our sample was representative of the local community. Following a thorough review of each patient's medical history, which included chronic conditions, socioeconomic status, and dental hygiene practices, a dentist qualified to perform this type of evaluation examined each patient for evidence of decay using well-known metrics such as the Decayed, Missing, and Filled Teeth (DMFT) score. Based on previous research, serological tests (detection of H. pylori antibodies) were performed to determine the presence of H. pylori in order to minimize discomfort and avoid the bias that occasionally arises with more intrusive gut collection methods. THE AIM: of this study is to provide a significant contribution to the present literature with genuine potential to influence public health policies and dental care programs targeted at reducing health inequities in the region, provided that the study is carefully planned and some innovative data management is done. RESULTS: This result essentially shows that additional interdisciplinary research is required to adequately map out the cause-and-effect relationship between H. pylori and dental caries. Curiously, it also supports previous research that suggested this bacterium might contribute to oral disorders, supporting the notion that a comprehensive, multimodal strategy is required to address oral and general health concerns. By lowering the rate of dental decay, local, community-driven initiatives to enhance oral hygiene may hold the key to minimizing the effects of H. pylori. The study emphasizes that reducing the disparities in oral health observed in Tripoli may depend on making dental treatment more accessible, particularly for those from lower-income backgrounds. Conclusion: An infection with Helicobacter pylori is substantially linked to a higher prevalence of dental caries. Both dental decay and H. pylori infection are significantly influenced by age, with poorer oral health being seen in older people. Infrequent dental checkups and poor oral hygiene are two factors that raise the DMFT index. People with diabetes, high blood pressure, and acidity have far worse tooth health. Dental caries is significantly influenced by economic level, with slightly worse outcomes for those with greater incomes. The DMFT score and H. pylori prevalence do not seem to be significantly impacted by smoking or gender. This study confirms our presumptions between H. pylori and dental cavities while highlighting the critical necessity for integrated healthcare systems.

ABSTRACT

This study aimed to explore EFL teachers’ perceptions of the 21st-century PD program in six primary schools in Al Jabal Al Gharbi district. 31 teachers participated in the study. The mixed-research approach was used to conduct the research. A structured questionnaire and a semi-structured interview were used to gather the data. The results revealed that participants acquired several teaching skills, such as new techniques for teaching vocabulary, speaking, and listening language skills, from the 21st-century PD program. Furthermore, the participants reported positive changes in their students’ outcomes, including improved speaking, listening and vocabulary. The findings also revealed some complications in implementing the PD program, including a lack of resources and administrative support at some schools.

Urinary tract infections (UTIs) are considered the most widespread bacterial infections and among the most common nosocomial infections, second only to lower respiratory tract infections. The risk of developing a UTI increases with age, making UTIs among the most commonly diagnosed infections in elderly people, representing a significant public health problem. This study aimed to isolate and detect the microbial responsible for urinary tract infections in elderly individuals and determine their resistance patterns and sensitivity to antibiotics among Libyan patients in Tripoli city. The study was conducted simultaneously in Alsharik, Eltafoq, and Ibn Al Nafis laboratories in Tripoli, Libya, during July and August 2024. One hundred and one urine samples were collected from elderly participants suffering from UTI symptoms (38 males and 63 females), with ages ranging from 60 to 97 years. Isolation, biochemical identification, and antibiotic susceptibility analyses were performed. Thirteen antibiotics were testedin this study. Among the 101 isolated samples from elderly patients with suspected UTI, females had a higher prevalence of bacterial infections (62.4%) compared to males (37.6%). The highest number of infections was in the 60–69 years age group (45.4%). Gram-negative organisms accounted for 91.1% of isolates compared to Gram-positive organisms. Escherichia coli was the most common organism isolated (43.6%), followed by Klebsiella pneumoniae (29.7%). Most isolates were resistant to Ampicillin (31.7%) and Amoxicillin (23.8%), followed by Tetracycline (10.9%). The Gram-positive organisms Streptococcus pneumoniae, Enterobacter spp., and Staphylococcus aureus were most susceptible to Amoxicillin, Amikacin, and Meropenem, with sensitivity rates of 75%, 66.7%, and50%, respectively. E. coli was more susceptible to Imipenem (25%), Amikacin (22.7%), and Nitrofurantoin (13.6%), whereas Amoxicillin and Sulfamethoxazole/Trimethoprim showed lower efficacy. Gram-negative bacteria were the main cause of UTIs in the study population, mainly belonging to the E. coli and Klebsiella families. Age and gender were significant factors in determining UTI etiology, and considering these factors can improve the accuracy in identifying causative uropathogens and guide empirical treatment.Keywords:UTI, Antibiotic Resistance, Sensitivity Antibiotics, Uropathogenic E.Coli

Abstract The integration of Artificial Intelligence (AI) in education is progressively transforming teaching, learning, and administrative practices globally, with significant potential for application in Libya. the purpose of this research is to discuss and evaluate the benefits and risks of AI in the education system of Libya. To achieve this, a descriptive research approach was employed, using a questionnaire distributed to a selected group of educational professionals in Libya. The sample consisted of 1,000 participants, and the survey was conducted via the WhatsApp application. The results highlight that personalized learning received the highest mean score of 4.19, indicating strong agreement on its effectiveness. Automation of administrative tasks (mean 3.80) and data-driven decision-making (mean 3.98) also showed favorable perceptions, with low variances around 0.24 0.25, reflecting consistent responses. Improved student engagement had a mean of 3.91 and a standard deviation of 0.49, similar to others, suggesting overall positive and uniform attitudes. Additionally, most responses clustered around neutral to moderate agreement, with modes of 3 or 4, showing balanced or mildly supportive opinions. Variance values ranging from 1.39 to 1.48 suggest a moderate spread, indicating some disagreement among participants. Standard deviations around 1.18 to 1.21 confirm a consistent yet moderate level of variability, without extreme polarization The obtained results show strong agreement on the benefits of educational innovations, especially personalized learning, which had the highest mean, and all aspects scored highly with low variability, indicating consistent positive perceptions. At the same time, the conclusions reveal moderate concern among respondents about the cost and inequality issues related to AI in education, with variance and standard deviation values reflecting a consistent spread of opinions. This research contributes to the academic discourse on the impactful integration of AI in academic institutions and establishes positive perceptions for continual enhancement. Overall, funding infrastructure emerges as the most pressing challenge, with general agreement across participants. Keywords. Artificial Intelligence, Education, Personalized Learning, Libya. 

This research investigated the challenges medical university students encounter in learning

technical vocabulary. A quantitative research approach was adopted. 61 first-year medical

students at the University of Gharyan participated in the study. A structured questionnaire was

used to gather the data. The findings revealed that medical university students encounter

several challenges in medical vocabulary learning, including pronunciation, spelling, meaning and use. The results also indicated that medical university students struggle to recall some

medical terms, which could be attributed to cognitive overload. The researchers suggest

revaluating the current English medical programs at the Faculties of Medicine in Libya.

Teaching vocabulary in context, highlighting the grammatical categories of words, drawing

distinctions between synonyms through examples, and training students on using medical

words through interactive activities could enhance the current English medical programs.

This paper proposes a novel robust blind color image watermarking technique that combines entropy analysis, lifting wavelet transform (LWT), QR factorization, and discrete cosine transform (DCT) for copyright protection. The RGB components of the color image are first separated, and the R component is then subjected to the 2-level LWT. Following DCT is applied to the 2-level LWT's high-frequency sub-band, the DCT coefficients are separated into 4x4 non-overlapping blocks. Each chosen block is then subjected to QR factorization, and the watermark is embedded in the first row and first column element of the upper triangular matrix. Numerous simulated tests show that the presented scheme is highly imperceptible and robust to attacks. The presented watermarking scheme performs better than the others in terms of invisibility, according to comparisons with comparable schemes.
