In this paper, we propose the analytical approach for adaptive decode-and-forward (ADF) relaying vehicle-to-infrastructure (V2I) schemes consisting of N<sub>D</sub>-symbol burst data transmission based on pilot symbol assisted-channel estimation (PSA-CE) methods over quasi-static Rayleigh fading channels. At first, we focus on the error-event at relaying on(More)
In this paper, we propose bicycle collision avoidance (BCA) algorithms and analyze their performance. As typical type accidents related with bicycles, we consider both intersection collision and rear crash. Then, the rear crash avoidance (RCA) algorithm and the intersection collision avoidance (ICA) algorithm are respectively developed by utilizing(More)
As a tocolytic agent, ritodrine has been used in European and Asian countries but has lost popularity due to safety concerns. This study aimed to investigate the relationship between adverse drug events caused by ritodrine and the CACNA1C polymorphisms in preterm labor patients. Data were collected from medical records including maternal age, gestational(More)
BACKGROUND AND OBJECTIVES Empirical evidence is lacking on the cumulative disease burden of obesity and hypertension and its impact on cardiac function and exercise capacity. The purpose of this study was to determine whether the presence of obesity and hypertension together was associated with cardiac dysfunction and exercise capacity. SUBJECTS AND(More)
PURPOSE The aim of this study is to evaluate the relationship between abdominal subcutaneous fat thickness measured by ultrasonography (US) and serum lipid profile and liver transaminases in obese children. METHODS One hundred and sixty-six children diagnosed with obesity from May 2001 to December 2013 were included in this study. Data on serum lipid(More)
In order to support the mobility of vehicles and reliable services in the Institute of Electrical and Electronics Engineers (IEEE) 802.11p/wireless access in vehicular environments (WAVE) network, cell planning and coverage optimization are critical issues. In light of this, we employed the IEEE 802.11p/WAVE test-bed located at the Chungju campus of the(More)
In this paper, we propose the intersection collision avoidance (ICA) algorithm with V2X communications. The ICA algorithm is developed based on both basic safety message (BSM) and signal phase and timing (SPaT) message of the SAE J2735 dedicated short range communications (DSRC) message set dictionary standard. Furthermore, the developed ICA algorithm is(More)
The Convergence-Information Technology Research Center for Next-Generation Intelligent Transport System (C-ITRC for NGITS) deployed the IEEE 802.11p/Wireless Access in Vehicular Environments (WAVE) test-bed located in the Chungju campus of Korea National University of Transportation (KNUT). We developed the WAVE Geometric Measurement Studio (WGMS), which(More)
