مؤخرًا برزت عدة تساؤلات حول طبيعة علاقة الذكاء الاصطناعي بالذكاء البشري، فالهدف من هذه الدراسة هو مناقشة فرضية أن العلاقة بين الذكاءين يجب أن تُبنى على التكامل لا على التنافس. واعتمدت الدراسة على المنهج الوصفي التحليلي من خلال مراجعة الأدبيات الحديثة التي تناولت الإمكانات التكاملية بينهما.. كما واوصت الدراسة بتبني اطار تعاوني تشاركي (الذكاء التشاركي) والذي يعزز التفاعل الايجابي بين الانسان والآلة..

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.

Abstract: Vitamin D deficiency is a public health concern affecting many individuals as it is highly prevalent in

all parts of the world. Recent studies have reported an association of vitamin D deficiency with cardiometabolic

alterations such as dyslipidemia. The study aimed to evaluate vitamin D and lipid profile levels among the Libyan

adult population and investigate the correlation of vitamin D deficiency with the alteration of lipid profile levels.

A cross-sectional study was conducted at Janzour Hospital among 193 subjects (107 males and 86 females) whose

ages ranged between 20 and 50 years over three months from Sept to Dec 2023. Vitamin D, cholesterol,

triglyceride, low-density lipoprotein, and high-density lipoprotein levels were estimated. The total mean vitamin

D levels were 8.31±4.74, 23.83±2.78, and 42.67±7.95 ng/dl for deficiency, insufficiency, and sufficiency,

respectively. The findings revealed significant alterations in cholesterol (increase), triglyceride (increase), LDLcholesterol

(increase), and HDL-cholesterol (decrease) among subjects who had vitamin D deficiency or

insufficiency as compared to subjects having vitamin D sufficiency. Vitamin D levels were negatively correlated

with cholesterol, triglyceride, and LDL cholesterol, and they were positively associated with HDL cholesterol.

The incidence of dyslipidemia is higher in the vitamin D deficiency group than in the insufficiency and sufficiency

groups. It is essential to frequently monitor lipid profiles among vitamin D-deficient individuals to avoid

subsequent disorders or damages associated with the alterations of lipid profile patterns.

Chamomile (Matricaria chamomilla L.) is a medical plant known for its antioxidant properties, which are attributed to bioactive compounds such as flavonoids and terpenoids. The study aimed to compare the antioxidant efficacy of natural chamomile with three commercial brands, A (Italian chamomile (Sonny)), B (Italian chamomile (Restora)), and C (German chamomile (UTZ)) available in Libyan markets. Methanol extracts of all samples were prepared by maceration, and antioxidant activity was evaluated using the DPPH radical scavenging assay. All data were expressed as mean ± standard deviation (SD). Statistical analysis was performed using one-way ANOVA, with A p-value < 0.05, which was considered statistically significant. Results revealed significant differences in IC50 values, with natural chamomile exhibiting the highest potency (IC50 = 3.35 mg/ml ± 0.055), followed by Brand A (IC50= 3.56 mg/ml ± 0.04) and Brand C (3.88 mg/ml ± 0.21). Brand B showed the weakest activity (IC50= 5.01 mg/ml ± 0.04). The statistical analysis confirmed the superiority of natural chamomile over commercial variants. Our findings suggest that processing methods, storage conditions, or potential additives in commercial products may degrade bioactive compounds, reducing antioxidant efficacy. This study highlights the advantage of minimally processed natural chamomile for optimal antioxidant benefits, and it underscores the implications for consumer choice and quality control in the manufacturing of herbal products.
