This paper presents a design of two dimensional receiving coils to provide hundreds of milli-watt power via inductive link to in vivo robotic capsules, whose orientation are practically undetermined. The wireless power transmission system consists of a transmitter powered by class E power amplifier, and receiver with 2-dimensional antenna, rectifier, and(More)
Improving energy efficiency has been widely regarded as one of the most cost-effective ways to improve sustainability and mitigate climate change. This paper presents a sequential slack-based efficiency measure (SSBM) application to model total-factor energy efficiency with undesirable outputs. This approach simultaneously takes into account the sequential(More)
Polymerase Chain Reaction (PCR) is an amplification method of genetic materials and is used in almost every process that includes genetic material treatment. Conventional PCR machines control the process with a computer that is connected with a wire, limiting the mobility and requiring an expensive, high technological installation skill. This paper utilizes(More)
This paper presents a PC-based thermal cycler with a local-host architecture, where a PC is employed as the host. The local system only executes the thermal cycling process and the PC is responsible for the management of PCR protocols with a convenient GUI. The presented local-host system greatly reduces the development time and the maintenance cost,(More)
Polymerase chain reaction (PCR) is a method of amplifying DNA which is normally carried out with a thermal cycler. To obtain more accurate and reliable PCR results, the temperature change within the chamber of the thermal cycler needs to be verified and calibrated regularly. Commercially available temperature loggers commonly used for temperature(More)
Localized radiotherapy (RT) can cause immune dysfunction. Bojungikki-tang is known to restore immune function. We investigated the absolute counts and percentages of peripheral blood (PB) lymphocyte subtypes in end stage cancer patients before and after RT and after oral administration of Bojungikki-tang water extract (BJITE) and to evaluate the changes(More)
This paper investigates the calibration effect of urine biomarkers by creatinine. The biomarkers were obtained from each urine sample of 256 patients (cancer: 137, benign: 119). The logistic regression of the combinations of 2 biomarkers calibrated by creatinine concentration was compared with that of the 3 biomarkers including creatinine. The average AUC(More)
