The feasibility and reliability of combined use of transcranial and direct cortical motor evoked potential (MEP) monitoring during unruptured aneurysm surgery were evaluated. Forty-eight patients with unruptured cerebral aneurysms underwent craniotomy and neck clipping accompanied by muscle MEP monitoring. MEPs were elicited successfully by transcranial(More)
Software birthmarks are unique and native characteristics of a binary executable program that can be used for detecting software piracy. API (Application Programming Interface) calls in an MS Windows binary executable can be used as software birthmarks when there are no source codes available to detect software similarity. However, it is inefficient to(More)
BACKGROUND Capillary hemangiomas are neoplasms involving skin and soft tissue in infants. These lesions rarely involved an intracranial space and reported age distribution ranges from infancy to middle age. We report an extremely rare case of rapidly rising intracranial capillary hemangioma in an elderly woman. CASE DESCRIPTION The 82-year-old woman(More)
Software birthmark is a technique for preventing and identifying plagiarism through illegal software modification using feature information from said software. Presently, research on birthmarks differentiates between static birthmarks and dynamic birthmarks according to the way of extracting feature information. Dynamic birthmarks are advantageous because(More)
Isolated oculomotor nerve palsy is well known as a symptom of microvascular infarction and intracranial aneurysm, but unilateral oculomotor nerve palsy as an initial manifestation of chronic subdural hematoma (CSDH) is a rare clinical condition. We report a rare case of an 84-year-old woman with bilateral CSDH who presented with unilateral oculomotor nerve(More)
Software piracy causes serious problems in many software-related industries. Dynamic binary similarity comparison methods can be used to detect software piracy. However, such methods generate large logs that require long periods of time to perform similarity comparisons. In this paper, we propose an extraction method that facilitates effective binary(More)
BACKGROUND Migrant health is becoming public health issues, as the migrant populations are increasing and their length of stay is prolonged. This study aims to analyze the differences in prevalence of chronic diseases among migrants according to length of stay and residential status. METHODS An initial population pool were 3,024 who were assessed with(More)
