The runtime creation of pedagogically coherent learning content for an individual learner's learning preferences is a considerable challenge. By selecting and combining appropriate learning assets into a new learning object a learner's needs and preferences may be accounted for. There are a number key aspects that need to be addressed in order to perform… (More)
This article describes a learner modeling strategy that is employed by an adaptive learning system in order to provide each learner with a personalized e-Learning experience. Parameters related to the learners' prior knowledge, goal and learning style constitute the basis of the personalization and the adaptivity of the mentioned learning system. The… (More)
The authors present 344 (230 females, 114 males) surgical cases of intracranial meningioma. A total of 370 interventions (344 primary procedures, 10 reexplorations for neurologic deterioration, 16 operations for recurrence) were made. Mean follow-up was 38 months. The overall evaluation revealed that 306 (88.95%) patients were completely normal or in a… (More)
The authors present a patient who underwent transsphenoidal surgery for a pituitary adenoma and afterward developed late, severe rhinorrhea and tension pneumocephalus. The patient was treated conservatively.
The benefits of Open Learner Model for learners have been widely demonstrated: supporting learning and metacognition, facilitating self-monitoring and planning, improving self-assessment skills… In this paper, we investigate the benefits of using an OLM for teachers. We present Hızlıgo, a speed reading application and the LEA's Box OLM, a competency-based… (More)
We present 6 patients with a definite diagnosis of von Recklinghausen's neurofibromatosis. All of them had aqueductal stenosis and hydrocephalus requiring surgical intervention because of clinical signs of increased intracranial pressure confirmed by pressure measurements.
Medulloblastoma metastasising extraxially is a rare entity. The mechanisms that cause such spread are not fully understood. We present a patient who developed a low thoracic metastasis three years after surgical removal of a posterior fossa medulloblastoma. A spinal metastasis penetrated the dura, thus becoming extradural and from this tumour a completely… (More)
The authors describe a patient with Behçet's disease who suffered from intracerebral hemorrhage 2 1/2 years after the initial diagnosis. There is strong evidence that this situation is not merely a coincidence; rather, these two abnormalities have a cause and effect relationship.
Third ventriculostomy is an operating technique which is mostly used in benign adult aqueductal stenosis. The most important stage of this operation is the manipulation of the basal membrane of the third ventricle. A technique which facilitates the opening of the posterior wall of the third ventricle is presented.
