Tracking Students’ Mental Engagement Using EEG Signals during an Interaction with a Virtual Learning Environment

引用

Journal of Intelligent Learning Systems and Applications 2019年第1期11卷 1-14页

作者： Asma Ben Khedher im.ne Jraidi Claude Frasson Department of Computer Science and Operations Research University of Montreal Montreal Canada

Monitoring students’ level of engagement during learning activities is an important challenge in the development of tutoring interventions. In this paper, we explore the feasibility of using electroencephalographic signals (EEG) as a tool to monitor the mental engagement index of novice medicine students during a reasoning process. More precisely, the objectives were first, to track students’ mental engagement evolution in order to investigate whether there were particular sections within the learning environment that aroused the highest engagement level among the students, and, if so, did these sections have an impact on learners’ performance. Experimental analyses showed the same trends in the different resolution phases as well as across the different regions of the environments. However, we noticed a higher engagement index during the treatment identification phase since it aroused more mental effort. Moreover statistically significant effects were found between mental engagement and students’ performance.

Food and Nutrition Sciences 2014年第15期5卷 1529-1537页

作者： Fatima Zohra El Kadi Amina im.ne Bénali Mohammed Bénali Slim.ne Belbraouet école de Nutrition Université de Moncton Moncton Canada Laboratoire de Biotoxicologie Département de Biologie Faculté des Sciences de la Nature et de la vie Université D Liabés Sidi Bel Abbés Algérie

The objective of this work was to determine the sodium metabisulphite (NaMBS) subchronic toxicity used as a food additive in Algeria. Three groups of female Wistar rats were treated with 0.25%, 1% and 4% of NaMBS in their drinking water for 90 days. An immunization protocol was conducted during the experiment. Mortality, comportmental and weight modifications, and food and water consumption were recorded. At the end of the experiment, the control and experiment rats were killed, and their blood and organs were removed. immunoglobulin levels were evaluated;biochemical and hematological parameters were investigated. Our results showed that the administration of NaMBS at 1% and 4% had significant effects on body weight, food and water consumed. There was an increase in biochemical parameters (calcium, urea, creatinine, uric acid, transaminases) and decrease immunoglobulin levels. The hematology revealed a decrease in red blood cells and hemoglobin, as well as leucocytosis. Physiological study showed enlarged spleen, kidney, liver and stomach. In light of our results, we can conclude that subchronic intake of NaMBS 1% and 4% seems to alter immune function, biochemical, hematological and physiological para-meters in Wistar rats.

Theoretical Study on Properties of new Isotope 265Bh

Communications in Theoretical Physics 2006年第4期45卷 681-686页

作者： ZHANG Hong-Fei ZUO Wei LI Jun-Qing Soojae im MA Zhong-Yu CHEN Bao-Qju Institute of Modern Physics the Chinese Academy of Sciences Lanzhou 730000 China Graduate School of＇the Chinese Academy of Sciences Beijin 100049 China Center of Theoretical Nuclear Physics National Laboratory of Heavy Ion Accelerator Lanzhou 730000 China Institut für Theoretische Physik Justus-Liebig-Universitaet Heinrich-Buff-Ring 16 D 35392 Giessen Germany China Institute of Atomic Energy Beijing 102413 China

The properties of nuclei belonging to the newly observed α-decay chain starting from ^265Bh have been studied. The axially deformed relativistic mean-field calculation with the force NL-Z2 has been performed in the blocked BCS approximation. Some ground state properties such as binding energies, deformations, spins, and parities, as well as Q-values of the a-decay for this decay chain have been calculated and compared with known experimentai data. Good agreement is found. The slngle-particle spectrum of the nucleus ^265Bh is studied and some new magic numbers are found, while the magnitudes of the shell gaps in superheavy nuclei are much smaller than those of nuclei before the actinium region, and the Fermi surfaces are close to the continuum. Thus the superheavy nuclei are usually not stable. The a-decay lifetimes in the ^265Bh decay chain are evaluated by different formulae, and compared with experimental data. The methods which give good agreement with the data are selected.

Occupational Allergic Contact Dermatitis in Tunisia: Epidemiology and Occupational Outcome

引用

Occupational Diseases and Environmental Medicine 2018年第3期6卷 107-117页

作者： Asma Aloui Maher Maoua Houda Kalboussi im.ne Kacem Sana El Guedri Aicha Brahem Olfa El Maalel Faten Debbabi Souhaiel Chatti Néjib Mrizak Department of Occupational Medicine Faculty of Medicine of Sousse University of Sousse Farhat Hached Teaching Hospital Sousse Tunisia

Background: Occupational allergic contact dermatitis (ACD) is one of the most frequent diseases on the workplace worldwide. Its national incidence and prevalence were not previously studied in Tunisia. Objective: To assess incidence of occupational allergic contact dermatitis and its occupational outcome in Tunisia. Methods: Descriptive epidemiological study of all cases of occupational allergic contact dermatitis reported from 2002 to 2012 in Tunisia and recognized by the medical commissions of the National Health Insurance Fund. Results: 315 cases of occupational ACD were collected representing an annual incidence of 31.65 cases/100.000 workers in the private sector in Tunisia. The mean age of our population was 42.70 ± 9.02 years with a male predominance (sex ratio 3.03). The most affected sectors were the clothing sector (14.3% of cases) and the cement industry (13.7% of cases). Patch tests were positive in 188 patients (59.67%). The most frequently positive allergen was potassium dichromate in 27.3% of the cases. Overall, 25.4% of patients had lost their jobs. After multiple binary logistic regression, job loss had a statistically significant relationship with localization of lesions on the face and on dominant hand. Conclusion: Occupational ACD is frequent in Tunisia and is responsible for an important rate of job loss. Preventive measures must be reinforced, especially the wearing of protective gloves.

Symptomatic Tarlov Cysts and Occupational Outcome: A Case Report

Occupational Diseases and Environmental Medicine 2023年第2期11卷 115-121页

作者： Belhadj Chabbah Narjes Aloui Asma Athimni Zeineb Nakhli Rania Bouhoula Maroua Chelly Farah Chouchane Asma Kacem im.ne Maoua Maher Brahem Aicha Kalboussi Houda Elmaalel Olfa Chatti Souhail Mrizek Najib Faculty of Medicine of Sousse University of Sousse Sousse Tunisia Department of Occupational Medicine University Hospital Farhat Hached Sousse Tunisia Department of Occupational Medicine University Hospital Sahloul Sousse Tunisia

Tarlov cysts are often asymptomatic and incidentally discovered. However, in few cases, these cysts can be symptomatic and may manifest as chronic low back pain. We report a case of a Tarlov cyst incidentally diagnosed by MRI in a wiring factory worker complaining of chronic low back pain exacerbated with the carrying of heavy loads and the hyper solicitation of the lumbar spine during his professional activity. The clinical manifestations of symptomatic Tarlov cysts can influence the life quality of patients and have enormous repercussions on their work ability, which in some cases can lead to job loss. Thus, the socio-professional aspects of symptomatic Tarlov cysts should not be underestimated and maintaining these patients in employment should be considered from the outset as an objective in its own right in the management.
