Abstract:

This study examines the challenges of integrating theoretical preparation with practical training in Colleges of

Education, focusing on the Faculty of Education in Tiji, University of Zintan. Using a descriptive-analytical

method, data were collected from 20 faculty members and 33 student teachers through structured questionnaires.

Results showed that both groups face difficulties in linking theory and practice, with faculty members reporting

higher role conflict (M = 3.70) than students (M = 3.39), a statistically significant difference (p = 0.013). The

dominance of theoretical content, limited administrative support, and short practicum periods contribute to this

gap. The study recommends curriculum redesign, better supervision, and investment in modern educational

laboratories to strengthen the connection between academic and professional preparation.

Tabular data is a common format for storing information in rows and columns, representing data entries and their associated features. Existing deep learning models designed for tabular data often rely on uni-dimensional feature selection mechanisms, which fail to adequately capture contextual dependencies of feature importance. This can result in missed crucial interactions, bias towards high-impact features, and limited generalization in attention generalization. To overcome these challenges, this study introduces a novel Iterative Feature Exclusion module that enhances the estimation of feature importance. The proposed module iteratively excludes a single feature from the input data and computes attention scores that represent the impact of each feature on the prediction. By aggregating the attention scores across iterations, the module generates a refined representation of feature importance that captures both the global and local feature interactions. The effectiveness of the proposed module was evaluated on four public datasets, and the results consistently demonstrated its superior performance over state-of-the-art methods and baseline models in both feature ranking and classification tasks.

Background: Gastrointestinal stromal tumors (GISTs) are the major mesenchymal tumors of the gastrointestinal 

tract (GIT), which progress due to the mutation in TKI and PDGFR-α receptors. It shows asymptomatic conditions 

however, become malignant due its large size and produce abdominal pain. Several surgical managements have 

been applied to diagnose patients with GIST, but these increase the risk of tumor recurrent rate. Therefore, 

adjuvant therapies contribute to preventing this challenge with several side effects and post-operative 

complications. A 42-year-old male patient from Libya with acute abdomen and GIST in small bowel (Jejunum) 

was diagnosed with complete excision besides lymph node dissection..Aim: To investigate numerous case reports 

through literature analysis regarding GIST along with a case presentation of the patient. Method: This research 

employed a literature-based study design. Previous case reports were screened from various online research 

platforms, including the National Center for Biotechnology Information (NCBI) and PubMed. A total of 37 cases 

were included through the search phrase "Case report on Gastrointestinal stromal tumor” .. Results: The findings 

revealed patient mean age (56.35) with most of the small intestine GIST (6.42 cm) site of origin, antibodies 

expression, and maximum mitotic cell counts.. Conclusion: The cases reported a risk of recurrence among GIST 

patients due to high mitotic counts and tumor size. Future researchers should address immune markers to reduce 

tumor recurrence among GIST patients. Stakeholders should implement proper treatment procedures with 

effective diagnostic methods.

poultry industry in Libya has recently experienced significant growth, which is critical for 

improving food security. However, Toxoplasma gondii poses a threat to this industry because it infects warm-blooded 

animals, including poultry. Chickens, particularly free-range chickens, may serve as an important reservoir for T. 

gondii, yet there are no reports regarding the prevalence of this disease in free-range chickens in Libya. Understanding 

the seroprevalence of Toxoplasma in poultry is crucial for mitigating these risks and ensuring the health of the poultry 

industry.

Aim: This study examines the occurrence of T. gondii infection in poultry and evaluates its impact on public health in 

Libya.

Methods: A total of 315 free-range chickens were procured, with blood serum samples collected from the Al-Marj 

(n = 123), El-Bayda (n = 104), and Derna (n = 88) districts. The sera were analyzed using the indirect enzyme-linked 

immunosorbent assay. The chi-square test was used to evaluate a significant correlation between the seroprevalence of 

T. gondii and area, sex, and age.

Results: The overall seroprevalence of T. gondii antibodies was 23.8%. Among the districts, the highest prevalence 

was recorded in Al-Marj (26.8%), followed by El-Bayda (25%) and Derna (18.2%). Male chickens had a higher 

prevalence rate (26%; 25/96) than females (22.8%; 50/219), although no statistical difference was found between the 

genders. Interestingly, older chickens had a significantly higher seroprevalence (39.2%; 31/79) than younger chickens 

(28.6%; 24/84).

Conclusion: In Libya, free-range chickens are a potential source of Toxoplasma infection, with older chickens having 

a significantly higher seroprevalence than younger chickens. These free-range chickens could pose an infection risk 

to humans.

Background: Oral candidiasis is a common opportunistic infection, but its epidemiology varies significantly by

region. Recent data on the prevalence, causative species, and risk factors for oral fungal infections in Libya,

particularly in the Gharyan area, is scarce. Objective: This study aimed to determine the incidence, distribution

of Candida species, and associated demographic and health-related risk factors for oral candidiasis in Gharyan,

Libya. Methods: A cross-sectional study was conducted from February to April 2025 with 140 participants. Oral

swabs were collected following a clinical examination and structured interview. Samples were cultured on

Sabouraud Dextrose Agar, and Candida species were identified using chromogenic agar. Statistical analysis was

performed using SPSS version 27, employing Chi-square tests and ANOVA. Results: The incidence of oral

candidiasis was 47.9% (67/140). Candida albicans was the predominant species (85.1%), followed by C.

glabrata (6.0%), C. krusei (3.0%), C. parapsilosis (3.0%), and C. tropicalis (3.0%). Among the analyzed risk

factors (age, gender, diabetes, hypertension, smoking, dental prostheses, oral hygiene, and pregnancy), only

pregnancy showed a statistically significant association with infection (χ² = 4.486, *p* = 0.034). All pregnant

women in the sample were in the infected group. Conclusion: The study reveals a high incidence of oral

candidiasis in Gharyan, predominantly caused by C. albicans. Pregnancy was identified as a significant risk factor,

underscoring the need for targeted oral healthcare and screening for pregnant women. The lack of association with

other classic risk factors warrants further investigation with larger samples

In recent years, researchers have been investigating different alloying elements to improve the corrosion resistance of magnesium alloys. One such element is Yttrium (Y), which has shown promising results in enhancing the corrosion resistance of magnesium alloys, such as EZ33. The susceptibility of magnesium alloys to corrosion is a major challenge, as corrosion can lead to structural degradation and compromise the integrity of the material, especially in harsh environments. The influence of a single yttrium (Y) addition on the corrosion resistance of the EZ33 Mg alloy was examined in this work. The corrosion resistance was measured using the loss weight method, and the specimens' surfaces were examined using an optical microscope and a scanning electron microscope. The results showed that the corrosion rate decreased with the addition of Y, and microstructure examination illustrated that the corrosion product film formed at the alloy treated with Y was more stable than those formed at the microstructure of the base alloy. Moreover, the corrosion attacked the area where the intermetallic phases formed, which was shown via optical microscope images. Y can be an effective alloying element to enhance the durability of Mg alloys in structural or biomedical applications.

This research studies the use of code-switching in English classes at secondary schools in Derj. Code-switching means using Arabic with English during the lesson. Many English teachers face problems when students do not understand explanations given only in English. For this reason, some teachers use Arabic to help students understand the lesson better. The study focuses on teachers’ opinions about using code-switching in the classroom. A questionnaire was used to collect data from 32 English teachers. Simple statistical methods were used to check the reliability of the questionnaire and to analyze the results. The findings show that most teachers accept the use of code-switching, but they do not support using it all the time. Teachers mostly use Arabic when explaining difficult vocabulary, grammar rules, or classroom instructions. They also believe that limited use of Arabic makes students feel more comfortable and willing to participate. However, teachers strongly agree that using Arabic too much can reduce students’ chances to practice English. For this reason, they prefer to keep English as the main language in class and use Arabic only when it is really necessary
