الهدف من البحث: يهدف هذا البحث إلى تقييم تغير القدرة السمعية التالي لعملية تصنيع (خزع) الركابة والى دراسة تأثير عمر و جنس المرضى على مقدار انغلاق الفجوة الهوائية العظمية عقب التداخل الجراحي. طريقة إجراء الدراسة: شملت عينة الدراسة 80 مريض تم تشخيص إصابتهم بتصلب الركابة وأُجرِي لهم عملية تصنيع (خزع) ركابة باستخدام بديل لعظم الركابة و أحيانا طعم من شحمة الأذن. تم مقارنة القيم الوسطية لعتبات مخطط السمع الكهربائي عند التواترات 250-500-1000-2000-4000 Hz بالطريقين العظمي والهوائي قبل وبعد العمل الجراحي،كما تم حساب مقدار انغلاق الفجوة الهوائية العظمية. تمت دراسة النتائج إحصائياً باستخدام الاختبار t-Student وتحليل التباين p=0.05)Anova). النتائج: لُوحٍظ وجود فارق دال إحصائياً في القيم الوسطية للعتبات قبل و بعد العمل الجراحي بالطريق الهوائي عند التواترات المدروسة ( 0.001 p>)بينما لم تتأثر عتبات مخطط السمع بالطريق العظمي بجراحة الركابة. كان وسطي انغلاق الفجوة الهوائية العظمية عقب العمل الجراحي dB 28.6 الخلاصة: إن تدبير التصلب العظمي لعظم الركابة بالمدخل الجراحي المتبع في الدراسة الحالية قدأدى إلى تحسن نتائج القدرة السمعية لدى المرضى. لم تتأثر نتائج تحسن القدرة السمعية بجنس المريض إلا أن عمر مرضى عينة الدراسة قد أظهر تأثير دال إحصائي على تحسن القدرة السمعية عقب عملية الركابة.
Aim: To evaluate the hearing changes following stapedotomy surgery, and to investigate the potential effects of the age and sex of the patients on air-bone gap closure. Material and Methods: 80 patients diagnosed with otosclerosis and undergone stapedotomy surgery, were involved in this study. The hearing changes were evaluated by comparing the means of air and bone conductive measurements at 250-500-1000-2000 and 4000 Hz before and after surgery. In addition, the air-bone gap closure was determined. Data was analysed statistically using t-student and Anova tests (p=0.05). Results: There was a statistically significant difference in air conductive measurements before and after surgery (p<0.001), whilst the bone conductive values showed no differences. The mean of air-bone closure in the current study was 28.6dB.

This study aims to identifythe effect of hearing impairment on the the development
of communication of poor-hearing children. Validity and reliability have been examined
for the instrument and were approved to be usedin the current study.The instru
ment was
developed by the researcher and consisted of (32) items. The Sample consisted of (50)
families of the hearing impaired children.
The most frequent problemswerethe child’s request for repeating the speech and
were related to finding difficulties in continuing the conversation. The least common
problem was that the child moved away from others. The finding showed that there were
no significant statistical differences in the effect of gender of poor-hearing children on the
development of communicationand in their parents’ educathional level.
Understanding and executing natural language instructions in a grounded domain is one of the hallmarks of artificial intelligence. In this paper, we focus on instruction understanding in the blocks world domain and investigate the language understand
ing abilities of two top-performing systems for the task. We aim to understand if the test performance of these models indicates an understanding of the spatial domain and of the natural language instructions relative to it, or whether they merely over-fit spurious signals in the dataset. We formulate a set of expectations one might have from an instruction following model and concretely characterize the different dimensions of robustness such a model should possess. Despite decent test performance, we find that state-of-the-art models fall short of these expectations and are extremely brittle. We then propose a learning strategy that involves data augmentation and show through extensive experiments that the proposed learning strategy yields models that are competitive on the original test set while satisfying our expectations much better.
Standard architectures used in instruction following often struggle on novel compositions of subgoals (e.g. navigating to landmarks or picking up objects) observed during training. We propose a modular architecture for following natural language inst
ructions that describe sequences of diverse subgoals. In our approach, subgoal modules each carry out natural language instructions for a specific subgoal type. A sequence of modules to execute is chosen by learning to segment the instructions and predicting a subgoal type for each segment. When compared to standard, non-modular sequence-to-sequence approaches on ALFRED, a challenging instruction following benchmark, we find that modularization improves generalization to novel subgoal compositions, as well as to environments unseen in training.
The purpose of this study was to evaluate the esthetic changes
following functional and camouflage treatment in Class II Division 1
malocclusion patients.
Methods: cephalograms of 35 patients had Class II Division 1were selected.
Those in group 1
(n=15) were treated with functional appliance, and those in
group 2 (n= 20) were treated with fixed orthodontic appliance after
premolar extractions. 35 cephalometric variables were selected to evaluate
the esthetic changes following the orthodontic treatment.
Dependent t tests were used to compare the cephalometric variables at the
posttreatment stage and the cephalometric variables at the pretreatment
stage in each group, and Independent t tests were used to compare the
changes in cephalometric variables caused by the orthodontic treatment
between the groups.
Chin area is considered as a suitable donor site for autogenous bone grafts for
alveolar ridge reconstruction before dental implantation, using large trephine bur(10mm) considers one of
several ways which appeared for bone graft harvesting. The aim
of this search is to study radiographic
density changes following chin bone harvesting for dental implantology by using large trephine bur
depending on digital panoramic radiographs.
