    The purpose of this study is to examine the following the relationships between: 1) formal education (adequate and limited) in the Arabic language and English language proficiency and academic achievement in mathematics of Arabic-speaking students and 2) their attitudes towards L1 (Arabic) and L2 (English) and English language proficiency and academic achievement in mathematics. Eighty-six Arabic speaking third graders through eighth graders in the Midwestern state were selected on non-random sampling to participate in this study. Four main measures were used to collected data: (1) Parent Demographic Survey, (2) students\u27 attitudes survey, (3) Math component of the Michigan Educational Assessment program (MEAP), and (4) scores on the English Language Proficiency Assessment (ELPA). Descriptive analyses were used to summarize, classify and simplify the data collected from the two surveys. Inferential analyses, on the other hand, were used to investigate four research hypotheses of this study. Two statistical tests were used: 1) 2x2 factorial univariate analysis of variance (UNI-ANOVA) and 2) Lambda, and Goodman & Kruskal\u27s Tau. No significant relationships were found in all four hypotheses. Discussion about possible explanations as to why all research hypotheses were not supported is provided. Additionally, potential future research is also examined

    Students’ Readiness for the Implementation of E-learning in the College of Basic Education (CBE) in Kuwait during the Covid-19 Pandemic

    The main goal of this research was to investigate the readiness level of student-teachers in CBE in implementing E-learning. This study adopted a survey research design. The readiness of E-learning of the participants was assessed by a 39-item adopted survey. The study sample was 559 female undergraduate fall-time students majoring in teaching English as Foreign language (EFL). The analysis of the results found that the students have high levels of readiness towards E-learning that is due to the training they received online by their college. Additionally, no significant relationship was found between age and the level of readiness of the participants. Keywords: Readiness, E-leaning, Remote-emergency learning, acceptance, and training.

    The First Korean Case of Cutaneous Lung Tissue Heterotopia

    Get PDF
    Cutaneous lung tissue heterotopia is a very rare disorder where mature lung tissues develop in the skin. This is only the second known report of cutaneous lung tissue heterotopia, with the first by Singer et al. in 1998. A newborn infant had a hemangioma-like, freely movable mass connected to the anterior aspect of the sternal manubrium. Pathologic findings showed mature lung tissues with bronchi, bronchioles, and alveoli through the dermis and subcutis, and it was diagnosed as cutaneous lung tissue heterotopia. Cutaneous lung tissue heterotopia is hypervascular, so grossly it looks like a hemangioma. It can be differentiated from pulmonary sequestration, teratoma, bronchogenic cyst, and branchial cleft cyst by histology and the location of the mass. We describe the clinical, radiologic, and pathologic findings of a cutaneous lung tissue heterotopia, the first reported in Korea

    Influence of cyclic torsional loading on the fatigue resistance of K3XF instruments.

    Objective: To evaluate the torsional and cyclic fatigue behavior of post-machining heat-treated K3XF and conventional K3 nickel titanium (NiTi) instruments. Methodology: New K3XF and K3 files size 25/0.04 (n = 15) were tested in torsion and fatigue tests until fracture to determine the mean number of cycles to failure (NCF) and torque to failure. The cyclic torsional loading experiment was conducted; K3XF and K3 files (n = 30 in each group) were programmed to repeatedly rotate from zero angular deflection to 180° and then return to zero torque. Each rotation was defined as one cycle. Each file was subjected to 10 cycles of torsional loading. Fifteen files from each group were subsequently tested in torsion until fracture. Also, fifteen files subjected to cyclic torsional loading were examined using a three-point bending apparatus to obtain the mean number of cycles to failure. The fracture surface was examined with a scanning electron microscope. The crack-initiation sites and the percentage of dimple area of the whole fracture cross-sectional area were recorded. Results: There was no statistically significant difference between the new K3 and K3XF instruments in the maximum torque or maximum angular deflection. For the previously cycled files, K3XF demonstrated higher torque at fracture values than K3 Instruments (P < .05). The fatigue resistance of K3XF was significantly higher than K3 in both the new and previously cycled groups (P < .05). The NCF value of K3XF with torsional loading was even higher than that of K3 files without torsional loading, although there was no significant difference. New K3XF files demonstrated a significantly higher NCF than previously cycled files (P < .05). Conclusions: Cyclic torsional loading decreased the cyclic fatigue resistance of K3XF and K3 instruments although it did not affect their torsional properties. K3XF demonstrated better cyclic fatigue resistance than K3 for both new and previously torqued files.Dentistry, Faculty ofGraduat

    A Rare Case of Single-Rooted Mandibular Second Molar with Single Canal

    No full text
    The root canal anatomy of mandibular second molar teeth is known to be highly variable. Whilst the most frequently seen configuration is two mesial canals and one distal canal, other variations such as four canals, two canals, and C-shaped canal system do also exist. This case report describes the diagnosis and management of unusual root canal configuration of a mandibular second molar, with one canal in a single conical root, using the contemporary advancements in endodontics. Following clinical and radiographic examinations of the case, a diagnosis of symptomatic irreversible pulpitis with symptomatic apical periodontitis of tooth #47 was established, and root canal treatment followed by composite buildup and crown were planned. Clinicians should be aware of the different anatomic variants each tooth may exhibit. Furthermore, clinicians need to possess the proper knowledge and skills that allow them to utilize the diagnostic and therapeutic tools available at their disposal in order to optimize the quality of care provided to their patients
