An Ablative Evaluation
نویسندگان
چکیده
The goal of this project is to use through an intelligent, multimedia computer tutor to increase students’ interest in mathematics and their confidence in their ability to learn mathematics. Based on its student model, WhaleWatch selects problems of appropriate difficulty and provides help and instruction as needed. We present the results of a series of two studies. The first study showed that after using the tutor, girls increased in self-confidence at solving mathematics problems. Our second study was ablative, with the tutor’s hinting mechanism disabled. We have found that some students respond better (higher motivation and performance) when given less help. Our current goal is to integrate this knowledge into our next design.

Evaluation of response to I-131 ablative therapy in patients with differentiated thyroid carcinoma: A five year retrospective study [Persian]
Differentiated thyroid carcinomas usually show good uptake and response to I-131 ablative treatment. In this study, 90 patients following near total thyroidectomy who were referred to our institute for I-131 therapy are retrospectively studied. The patients are divided in two groups. Group 1 revealed complete ablation after one dose of I-131. Group 2 needed more than one dose of I-131 for...
متن کاملFeasibility of Extracted-Overlay Fusion Imaging for Intraoperative Treatment Evaluation of Radiofrequency Ablation for Hepatocellular Carcinoma.
BACKGROUND AND AIMS Extracted-overlay fusion imaging is a novel computed tomography/magnetic resonance-ultrasonography (CT/MR-US) imaging technique in which a target tumor with a virtual ablative margin is extracted from CT/MR volume data and synchronously overlaid on US images. We investigated the applicability of the technique to intraoperative evaluation of radiofrequency ablation (RFA) for ...

متن کاملThe Efficacy and Safety of Ablative Fractional Resurfacing Using a 2,940-Nm Er:YAG Laser for Traumatic Scars in the Early Posttraumatic Period
BACKGROUND Skin injuries, such as lacerations due to trauma, are relatively common, and patients are very concerned about the resulting scars. Recently, the use of ablative and non-ablative lasers based on the fractional approach has been used to treat scars. In this study, the authors demonstrated the efficacy and safety of ablative fractional resurfacing (AFR) for traumatic scars using a 2,94...
متن کاملThyroid Doppler ultrasonography and resistive index in the evaluation of the need for ablative or antithyroid drug therapy in Graves' hyperthyroidism.
BACKGROUND AND PURPOSE Graves' disease (GD) is the most common hyperthyroid disorder, but the therapeutic strategy for choosing between medical or ablative therapy has not been standardized. Thyroid hypervascularity is an important diagnostic feature in GD. This study collected Doppler ultrasonography data from patients with GD, Hashimoto's thyroiditis, and simple goiter to develop a hemodynami...
