Introduction: The level of knowledge and attitude of health professionals about breast cancer are important determinants. General objective: To study the knowledge, attitude and practice of health professionals of the hospital of the district of the commune IV on breast cancer. Methodology: This was a cross-sectional, prospective, descriptive, qualitative and quantitative study. The study period was from 01 October 2022 to December 2022. Results: In one week of survey, 110 health workers (intern, obstetrician nurse, general practitioners and specialists) received the survey sheet, 80 health workers informed it, a participation rate of 73%. The male sex was most represented at 63.75% with a sex ratio of 1.76. The average age was 39.59 years with extremes of 22 and 61 years. The clinical signs evoked by the participants were: breast nodule (81.25%), followed by breast discharge (48.75%). In relation to risk factors: interns and obstetrician nurses had no good knowledge, 51.72% of general practitioners had good knowledge, 43.48% of specialist doctors had good knowledge, and 5.88% of the wise had good knowledge. Conclusion: Breast cancer is a common pathology around the world, health professionals are at the forefront of the fight against breast cancer, and this fight cannot be effective without trained personnel.

We present the Peltier coefficient and thermal transport in quantum point contact （QPC）, under the influence of external fields and different temperatures. Also we obtain the oscillations of the Peltier coefficient in external fields. Numerical calculations of the Peltier coefficient are performed at different applied voltages, amplitudes and temperatures. The obtained results are consistent with the experimental data in the literature.

Missing Data Analysis of the Malian National Malaria Control...

作者： souleymane TRAORE 华东师范大学

学位级别：硕士

The presence of missing data in a database is a phenomenon that every researcher is liable to meet during their work. Although the bias which can be generated by an inadequate treatment of non-response is known for a long time [27], the knowledge on the effectiveness of various methods used in the treatment of missing values is not yet fully explored. This study aims to apply the techniques used in the treatment of missing values in the calculation of the morbidity and mortality linked to Malaria in Koulikoro in Mali during the period from April to June 2005. The main problem that missing data poses is that it is impossible not to take missing values into consideration during the application of a statistical analysis method. The majority of these methods had been developed to deal with a matrix of incomplete data. In this document the statistical theories on incomplete data sets are presented and then applied on the data of Koulikoro from Malian National Malaria Control Program.

Purpose: To show epidemiological and imaging aspects of congenital optic disc abnormalities diagnosed late. Method: It was a retrospective study, including all patients with congenital optic disc abnormalities diagnosed at a late age between January 2020 and October 2022 at the eye center of Abass Ndao Hospital. Complete ophthalmological examination was performed with eye imaging according to the cases. Results: 09 patients (10 eyes) were diagnosed with congenital optic disc abnormalities. The mean age was 29 years, with a sex ratio of 0.8. Three patients had consulted for unilateral decreased visual acuity since childhood, two for sudden vision loss and in four cases the diagnosis was fortuitous. Visual acuity was ranged from 1/200 to 20/20. Fundus examination showed myelinated retinal nerve fibers in four eyes, optic disc pit in three eyes including two complicated by maculopathy, two cases of morning glory syndrome and a case of pseudoduplication of the optic disc. Optical coherence tomography, ocular ultrasound B and OCT-Angiography were performed according to the cases. Conclusion: Congenital optic disc abnormalities are often diagnosed late. They are potentially amblyogenic and complications are not rare, worsening the visual prognosis. Their screening should be systematic by ophthalmological examination in newborns.

The magnetocaloric effect (MCE) achieved for La_(0.7)Sr_(0.3)MnO_(3)/Ta_(2)O_(5) composites has been investigated. The maximum value of magnetic entropy change of La_(0.7)Sr_(0.3)MnO_(3) composites is found to decrease slightly with the further increasing of Ta_(2)O_(5) concentration. It is shown that La_(0.7)Sr_(0.3)MnO_(3)/Ta_(2)O_(5) composites exhibit much more uniform magnetic entropy change than that of gadolinium. Moreover, the results indicate that the temperature range between 100 K and 400 K can be covered using the La_(0.7)Sr_(0.3)MnO_(3)/Ta_(2)O_(5) composites. Therefore, MCE makes the composites promising for room-temperature magnetic cooling applications.
