This study was conducted to evaluate the overall performance of a reverse blot hybridization-based assay, REBA HPV-ID® (Molecules and Diagnostics, Wonju, Korea) for genotyping human papillomaviruses (HPV). HPV Genotyping on 356 specimens examined cytologically was performed using the REBA HPV-ID®, and its results were compared with those obtained using the MyHPV DNA Chip® (Mygene, Seoul, Korea), DNA chip-based HPV genotyping assay. The results from this study showed that the positivity rate of the REBA HPV-ID® for abnormal cytological samples was higher (80.9%) than that of the MyHPV DNA chip (69.8%). In addition, the REBA HPV-ID® positivity rate with normal cytological samples was higher (64.4%) than that obtained using DNA chips (34.4%). Subsequently, sequence analysis was performed with specimens that generated conflicting test results. Sequence analysis confirmed that the specimens which were positive by REBA HPV-ID® did indeed contain HPV sequences. The results of this study suggest that the REBA HPV-ID® is a sensitive test for genotyping HPV of clinical specimens. © 2012 Wiley Periodicals, Inc.. Source

The GNSS positioning is widely used in the performance of forest tasks because of its convenience. Recently, mobile device could be used in positioning according to the development of smartphone technology. But the result of GNSS positioning without precise GPS involves large positioning errors. In case of forest area, these positioning errors increase more because tree canopies or topographies interfere with receiving the GNSS satellite signals. In this study, GNSS positioning experiment in the forest area with hand-held GNSS and smart phone were performed. As a result, accuracy analysis of these devices and usability of smartphone GPS for GIS data acquisition were presented. © Research India Publications. Source

This study was to evaluate the influence of hemp addition and extrusion conditions on properties of dough and bread. The extruded and non-extruded hemp/ rice flours with different hemp/rice ratio were mixed with wheat flour at 15% ratio. In those flour assays, extrusion greatly decreased the paste viscosities, while the addition of hemp inhibited the decrease of peak viscosity on the extrusion condition. The onset gelatinization temperature was extended due to the hemp addition. The test on dough properties showed that extrusion increased water absorption, arrival time, weakness, extensibility, and the volume after 105 min fermentation, and decreased the stability time and elasticity of dough, while hemp addition mainly increased the weakness and extensibility. For bread properties, extrusion decreased the specific volume, crust and crumb L value, and uniformed air cells, when the hemp addition increased the bread specific volume and decreased the hardness during storage time. © 2013 The Korean Society of Food Science and Technology and Springer Science+Business Media Dordrecht.

The purpose of study was to evaluate satisfaction with and usability of mobile academic electronic medical records (AEMR) for undergraduate nursing students' clinical practicum. After an AEMR application on mobile devices was applied to the experimental group while a PC-based EMR system was used for the control group as usual in the fall semester, 2014. Two items of practicum satisfaction such as preparation of lab test and understanding of the results, and nursing intervention and documentation were significantly higher in the experiment group. The findings of usability survey showed that students in the experiment group consider the use of mobile AEMR in their job would increase their productivity. © 2016 IMIA and IOS Press. Source

As healthcare systems demand that nurses be competent in using electronicmedical records for patient care, the integration of electronic medical records into nursing curricula has become necessary. The purpose of this study was to explore how students, new nurses, clinical instructors, and faculty perceive the integration of academic electronic medical records into the undergraduate clinical practicum. From January to February 2014, four focus group interviews with 18 participants were conducted based on purposive sampling. Content analysis was used on the unabridged transcripts to extract themes and develop meaningful categories. Three major themes and eight subthemes were revealed from the focus group interviews. The major themes were "electronic medical record as a learning tool for clinical practicum," "essential functions of academic electronic medical records," and "expected outcomes of academic electronic medical record." Participants expected academic electronic medical records to enhance students' nursing informatics competencies. The findings of this study can inform the process of developing academic electronic medical records for clinical practicum, which will then augment students' informatics competencies. © 2016 Wolters Kluwer Health, Inc.
