Why Handshakes Persist: Understanding the Influence of Beliefs on the Socializing Decisions of Young People During COVID-19 in Nigeria
Authors: Nche George C. 
Published: February 2025

Despite the global shift toward contactless greetings prompted by the COVID-19 pandemic, a substantial number of young people in Nigeria continue to engage in the practice of shaking hands. Previous empirical studies on COVID-19 and handshakes have primarily focused on adherence rates in different countries, with limited attention to understanding the underlying beliefs influencing adherence or non-adherence to preventive measures. This study explored the underlying beliefs that inform these socializing choices, shedding light on the socio-cultural and psychological factors affecting adherence to this age-old practice. Data were collected from twelve participants through in-depth interviews and analyzed thematically using a descriptive-analytical approach. The findings indicate that participants often feel immune to COVID-19, attributing this immunity to self-administered hydroxychloroquine and asserting divine, geographic (hot temperature), and demographic (being young) protection. Many also perceive the virus as similar to malaria and not considered severe. The implications of these findings for research and policy are discussed.

Geometry skills are an important component not only for students majoring in mathematics, but also for non-mathematics students, including students at the National Land College. This is because the science of geometry plays an important role in everyday life, such as measurement. This research is quantitative descriptive. The instrument used in this research was the VHGT test with 25 questions. The subjects in this research were 53 first semester D1 students majoring in cadastral measurement and mapping. The research results show that the highest level of geometric thinking that can be achieved is level 3 at 7.5%. The dominant geometric thinking level of students is at level 1 at 34%, followed by level 2 at 22.6%. The percentage of students who are at level 0 and not fit is 35.9%. Apart from that, the distribution of learning styles possessed by students is kinesthetic at 45% and is able to reach the highest level of geometric thinking, informal deduction level. Furthermore, visual was 37.7% and was able to reach the highest level of informal deduction and auditory was 5.6% which reached the highest level of thinking at the analytical level. In other words, the existence of students who are still at level 0 and not fit shows that their geometry skills still need to be improved.

The carboxylic acid group of quinolones was modified; so, we designed new quinolones derivatives with different antioxidants using Ligand Designer from Glide (Schrodinger LLC). The cap group and the linker were optimized through trying various aliphatic and aromatic residues. A new synthesized derivatives (IIa-Vb) were synthesized by esterification of (ciprofloxacin, gatifloxacin, nalidixic acid and norfloxacin) with antioxidants (a: vanillin, b: sesamol) through a glycol linker. Based on spectral data (NMR, ATR-FTIR) their structure were confirmed. The synthesized compounds were screened for their Pharmacological activities. In vivo, the anti-inflammatory effect of (IIa-Vb) compounds was estimated using a rat paw edema model and showed good activity for the end compounds IIa and IId, and their anti-inflammatory and antimicrobial effects were subsequently evaluated virtually-molecularly analyzed ; all prepared compounds show-interesting activity compared to the DMSO control group (solvent and control).in vitro, their antibacterial and antifungal activities were evaluated at concentrations: (12.5, 25 ,50 &100) mg. using well diffusion method ,for antibacterial activity compared to the reference drug (ciprofloxacin) the results showed significant activity from (IIa, IIb &IIIb) at 12.5 mg, (IIa, IIb ,IIIa ,IIIb,Iva & Vb) at 25 mg , IIIb at 50 mg in case of gram-negative bacteria (Escherichia coli); and (Staphylococcus aureus) (IIa, IIb &IIIb) at 12.5 mg, (IIa, IIb) at 25 mg , IIIb at 50 mg about gram-positive bacteria ,also they shown significant antifungal activity against (Candida albicans) compared with Fluconazole drug:(IIa, IIb and IVb) at (50 and 100) mg, (IIb) at 25 mg.

Abstract
The condition known as gestational diabetes mellitus (GDM) describes as an intolerance to glucoseThat first occur or progresses during pregnancy is the most common metabolic illness, and impacts up to25% of pregnant women. It has been demonstrated that omentin-1, which originates from both human placental and adipose tissue can serve as an insulin resistance mediator. It was initially identified as a secretory factor specific to visceral fat and showed that recombinant omentin-1 administration increased insulin-stimulated glucose transport in vitro which may increase insulin sensitivity, both glucose and insulin can down regulate omentin-1 which reduces levels in overweight women with polycystic ovarian syndrome. Moreover, those with diabetes and obesity had lower omentin-1 levels. Adipokines influence a variety of metabolic processes, including insulin sensitivity and secretion, inflammation, appetite control and adipogenesis regulation. This study was carried out with the aim of determining the serum omentin-1 level in pregnant women with and without gestational diabetes and determining any potential correlation between the adipokine omentin-1 and gestational diabetes. Multicenter case – control study, the cases collecting (pregnant women in the third trimester of pregnancy) will be divided into: Group A: 45 apparent healthy pregnant women without GDM as control. Group B: 45 pregnant women with GDM (patient). venous blood sample (5ml) in gel tube, of all subjects were drown after an overnight fast, and serum samples were stored at -20C° until omentin-1 assay by enzyme linked immune sorbent assay ELISA. Forty-five patients with gestational diabetes and 45 without were studied. Serum levels of omentin-1 were significantly lower in patients with gestational diabetes mellitus compared with those of the control group, p = 0.0001, hence this biomarker can serve as prognostic indicator for gestational diabetes.
