The purpose of this paper is to build a fundamental framework of discovering and analyzing a workflow-based social network formed through workflow-based organizational business operations. A little more precisely speaking, the framework formalizes a series of theoretical steps from discovering a workflow-based social network to analyzing the discovered(More)
Blood blister-like aneurysms (BBAs) are difficult to treat both surgically and endovascularly, and the optimal treatment remains controversial. The aim of this study was to evaluate the clinical and angiographic feasibility of multiple overlapping stents (≥3) with coiling for treating BBA. A retrospective review from four institutions identified ten(More)
The aim of this study was to review our experience with surgical clipping and endovascular treatment (EVT) of unruptured intracranial aneurysms (UIAs), with a special focus on complications. We retrospectively analyzed clinical and radiological data from patients who underwent surgery or EVT. Surgery was performed by one neurosurgeon, and EVT was performed(More)
The heritability of some individual depressive symptoms has been well established. However, the causal genes related to individual depressive symptoms and genetic effects on the courses of individual depressive symptoms are still unclear. We examined these issues in 241 Korean patients who met the DSM-IV-TR criteria for major depression. Patients entered a(More)
Clinical course of depression is variable. The serotonin transporter gene is one of the most studied genes for depression. We examined the association of serotonin transporter gene polymorphisms with chronicity and recurrent tendency of depression in Korean subjects. This cross-sectional study involved 252 patients with major depression. Patients were(More)
OBJECTIVE The Enterprise stent is used for endovascular treatment of complex intracranial aneurysms. The purpose of this study was to evaluate delayed thromboembolic events (DTEs) that developed more than 30 days after Enterprise stent-assisted embolization (SAC) and its associated risk factors. METHODS There were 125 consecutive patients (90 women and 35(More)
We investigated the effects of galantamine on cognitive subdomains in Alzheimer's disease (AD). Sixty-six patients with mild-to-moderate AD received open-label galantamine for 52 weeks. Cognitive function was measured using the Korean version of the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog-K). Response to galantamine was defined as(More)
Objective Equine-assisted activities and therapy (EAA/T) have been used as adjunct treatment options for physical and psychosocial rehabilitation. However, the therapeutic effects on resting-state brain function have not yet been studied. The aim of this study is to investigate the effects of EAA/T on participants with attention-deficit/hyperactivity(More)
Intracranial aneurysms suffer various interactions between hemodynamics and pathobiology, and rupture when this balance disrupted. Aneurysm wall morphology is a result of these interactions and reflects the quality of the maturation. However, it is a poorly documented in previous studies. The purpose of this study is to observe aneurysm wall thickness and(More)
BACKGROUND The aim of this study was to evaluate the clinical outcomes between endovascular treatment (EVT) and surgery of the ruptured posterior inferior cerebellar artery (PICA) aneurysms and suggest proper management strategies according to the PICA segment. METHODS We retrospectively analyzed clinical and radiological data of patients with ruptured(More)
