This paper develops a consistent nonparametric test for Granger causality in the context of strong-mixing process, which covers a large class of stationary processes including ARMA and ARCH models. The previously proposed tests require absolute regularity ($\beta$-mixing) more stringent than the strong-mixing condition. We prove the consistency of the test under a high level assumption on the approximation error of U statistic by its projection. Due to the sample splitting, the test statistic we propose is asymptotically normally distributed under the null.

We proposed dual mode pixel circuit in AMOLED (active matrix organic light emitting device). After light emitting period of OLED, we used it as a photo sensor. We measured photo current of OLED and simulated the proposed pixel circuit to verify it's function of dual mode, that is lighting and sensing.

Objectives: This report presents the case of a 21-year-old woman with lower extremity paresthesia in both feet due to polyneuropathy. Methods: The patient was treated using a Korean traditional complex treatment approach that included herbal medication, acupuncture, electroacupuncture, and moxibustion. We evaluated the improvements in the pain symptoms in both feet using the numeric rating scale (NRS); we also assessed for gait disturbance and used Digital Infrared Thermographic Imaging (D.I.T.I.) to evaluate minute changes in body temperature in diseased areas. Results: After administering the Korean traditional complex treatment, we observed a decrease in pain levels in both feet based on the NRS scores. We also observed improvements in gait disturbance and D.I.T.I. Conclusions: This case showed that the use of a Korean traditional complex treatment approach, consisting of herbal medication, acupuncture, electroacupuncture, moxibustion, had a positive effect on decreasing polyneuropathy symptoms.

Tracheopathia osteoplastica is a rare disease characterized by submucosal cartilaginous or bony projections into tracheobroncheal lumen with sparing of the posterior membranous portion of tracheobroncheal tree. The cause of this disorder is unknown. In the past, a majority of the cases were discovered incidentally at autopsy. But recently, antemortem diagnosis is increasingly reported after the introduction of computed tomography and bronchoscopy. We report a case of extensive tracheopathia osteoplastica diagnosed antemortem by computed tomography, bronchoscopic examination and biopsy.
