Suitable nozzle use and appropriate operation are the key factors that considerably influence the effectiveness of pest control. If the nozzle produces too high of a flow rate or droplet size that is too small is chosen, although the characteristics enable the nozzle to have the desired pest control effect, these characteristics can also lead to higher amounts of pesticide residue and relatively far spray drift distance. The longer the spray drift distance is the higher the possibility that toxic chemicals will harm the users’ health and pollute the neighboring rivers and air. In addition, if the spray drifts towards other neighboring farmlands, the crops within these farmlands will have higher pesticide residues and contain additional chemical compositions that should not be there. The purpose of this study is to analyze the important parameters of domestic agricultural nozzles in Taiwan, including flow rate, particle diameter (DV50) and drift distance, and finally to identify an appropriate way to classify the nozzles. The research was conducted using four different working pressures (5, 10, 15, and 20 kgf/cm2) to measure the actual flow rate and particle diameter (DV50) of each nozzle. The data of the flow rate was obtained by reading the lines printed on the side of the graduated cylinder, and the measurement of the particle diameter (DV50) was carried out using the Spraytec Malvern 2000 Particle Analyzer. After collecting the data as well as the distribution of the particle diameter, a simulation using DRIFTSIM software was run to find out the drift distance of different nozzles, and this simulation was carried out according to the actual ambient conditions in different cities in Taiwan so that the size of the buffer zone needed in different areas can be identified. The results showed that the particle diameters (DV50) of the nozzles were between 53.19 μm and 103.47 μm. When the ASABE S572.1’s method was utilized to classify the nozzles, all of the nozzles belonged to the range of extremely fine or very fine droplets. Since all of the nozzles generate DV50 of similar sizes, classification of domestic agricultural nozzles using this method is entirely improper. As a viable alternative, nozzles can be sorted according to the magnitude of the flow rate that contains DV50 of less than 100 μm.

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a useful, safe diagnostic modality for evaluating mediastinal and hilar lymphadenopathy. We report a 51-year-old male who presented with a left renal mass and multiple pleural masses without lung parenchymal lesions. The pleural masses were thought to be metastatic tumors or malignant mesothelioma. The patient underwent two percutaneous needle biopsies of the pleural mass, but the specimens were insufficient for a histopathological diagnosis. Because one pleural mass was adjacent to the right main bronchus, we decided to perform EBUS-TBNA for the pleural mass. As a result, sufficient core tissue was obtained with no complications, and the histopathological findings were consistent with metastatic papillary renal cell carcinoma. To our knowledge, this is the first case of using EBUS-TBNA for a pleural mass.

Background/Aims: Obstacles exist in facilitating hepatitis C virus (HCV) care cascade. To increase timely and accurate diagnosis, disease awareness and accessibility, in-hospital HCV reflex testing followed by automatic appointments and a late call-back strategy (R.N.A. model) was applied. We aimed to compare the HCV treatment rate of patients treated with this strategy compared to those without. Methods: One hundred and twenty-five anti-HCV seropositive patients who adopted the R.N.A. model in 2020 and another 1,396 controls treated in 2019 were enrolled to compare the gaps in accurate HCV RNA diagnosis to final treatment allocation. Results: The HCV RNA testing rate was significantly higher in patients who received reflex testing than in those without reflex testing (100% vs. 84.8%, P<0.001). When patients were stratified according to the referring outpatient department, a significant improvement in the HCV RNA testing rate was particularly noted in patients from non-hepatology departments (100% vs. 23.3%, P<0.001). The treatment rate in HCV RNA seropositive patients was 83% (83/100) after the adoption of the R.N.A. model, among whom 96.1% and 73.9% of patients were from the hepatology and non-hepatology departments, respectively. Compared to subjects without R.N.A. model application, a significant improvement in the treatment rate was observed for patients from non-hepatology departments (73.9% vs. 27.8%, P=0.001). The application of the R.N.A. model significantly increased the in-hospital HCV treatment uptake from 6.4% to 73.9% for patients from non-hepatology departments (P<0.001). Conclusions: The care cascade increased the treatment uptake and set up a model for enhancing in-hospital HCV elimination. (Clin Mol Hepatol 2021;27:136-143)

The Global Satellite Mapping of Precipitation (GSMaP) was used to estimate the accumulated rainfall in May from the Mei-Yu front in Taiwan. Rainfall estimation from GSMaP during 2002–2017 were evaluated using more than 400 local gauge observations, collected from the Taiwan CentralWeather Bureau (CWB). Studies have demonstrated that the GSMaP rainfall estimation estimates can be biased, depending on the target region, elevation, and season. In this experiment, we have evaluated GSMaP over three elevation ranges. The GSMaP systemic errors for each elevation range were identified and corrected using regression analysis. The results indicated that GSMaP estimation can be improved significantly through adjustment over three elevation ranges (elevation less than 50 m, elevation of 50–100 m, and elevation higher than 100 m). For these three elevation ranges, the correlation coefficient between the GSMaP estimations and CWB rainfall data was 0.76, 0.78, and 0.59, respectively. This indicated that the GSMaP estimation was more accurate for low-elevation regions than high-elevation regions. After the proposed approaches were employed to correct the errors, the bias errors were respectively improved by 5.64(13.7%), 7.33(38.4%) and 10.52(31.2%)mmfor low-, mid- and high-elevation regions. This study demonstrated that the local correction approaches can be used to improve GSMaP estimation of Mei-Yu rainfall in Taiwan.
