PURPOSES : Transportation researchers have contributed to try to both understand and accumulate scientifically how individuals move across time and space. Currently, data generated from household travel diary surveys have been used as the basis of travel behavior (or human mobility patterns) analysis in transportation planning and have been buoyed in a sustainability for decades. Against this backdrop, this study introduces mobile phone signaling big data that can convey more detailed human mobility information across time and space and supplement travel behavior analysis. METHODS: We propose a usable and useful dataset driven from the mobile phone signaling data for better travel behavior analysis. Several data-driven approaches have been tried to estimated and calculate variables inserted into the dataset. RESULTS: In the result, this paper discussed the promise of mobile phone based dataset to applications for inferring human mobility patterns applied to directly transport policy. CONCLUSIONS: It is our hope that this study will stimulate future studies on transportation planning and mobility analysis using mobile phone signaling data in Korea.
Treatment of Spontaneous Cervical Spinal Subdural Hematoma with Methylprednisolone Pulse Therapy

We report herein a case of hyperacute onset of spontaneous cervical spinal subdural hematoma treated with methylprednisolone pulse therapy that showed good results. A 57-year-old man was admitted for posterior neck pain and paraparesis which occurred an hour ago. MRI revealed a ventral subdural hematoma distributed from the level of C1 down to T3, compressing the spinal cord. Conservative management with methylprednisolone pulse therapy was administered considering the patient’s poor general condition. Although emergent surgical decompression is necessary in most cases of spinal subdural hematoma, conservative management with steroid therapy could be effective.
Serum and Cerebrospinal Fluid Neuron-Specific Enolase for Diagnosis of Tuberculous Meningitis

Purpose: Late diagnosis and treatment lead to high mortality and poor prognosis in tuberculous meningitis (TbM). A rapid and accurate diagnosis is necessary for a good prognosis. Neuron-specific enolase (NSE) has been investigated as a biochemical marker of nervous tissue damage. In the present study, the usefulness of NSE was evaluated, and a cut-off value for the differential diagnosis of TbM was proposed. Materials and Methods: Patient charts were reviewed for levels of serum and cerebrospinal fluid (CSF) NSE, obtained from a diagnostic CSF study of samples in age- and gender-matched TbM (n=15), aseptic meningitis (n=28) and control (n=37) patients. Results: CSF/serum NSE ratio was higher in the TbM group than those of the control and aseptic groups (p=0.001). In binary logistic regression,CSF white blood cell count and CSF/serum NSE ratio were significant factors for diagnosis of TbM. When the cut-off value of the CSF/serum NSE ratio was 1.21, the sensitivity was 86.7% and the specificity was 75.4%. Conclusion: The CSF/serum NSE ratio could be a useful parameter for the early diagnosis of TbM. In addition, the authors of the present study suggest a cut-off value of 1.21 for CSF/serum NSE ratio.
