Acute appendicitis is the most frequent cause of acute abdomen. However,bacteremia in patient with acute appendicitis is rare. A 34-year-old male patient presenting with fever and abdominal discomfort for two days showed leukocytosis,elevated C-reactive protein and erythrocyte sedimentation rate. Gram-negative rods were cultured in blood and empirical ceftriaxone was injected intravenously. On abdominal CT, wall enhanced and distended retrocecal appendix was recognized. Appendectomy was performed, which revealed suppurative inflammation without perforation. We report a case of acute appendicitis without perforation associated with Escherichia coli sepsis and atypical clinical manifestations in a healthy male.

In this paper, we propose a low-cost, low-power embedded environment-based deep learning lightweight model for input images to recognize laundry management codes. Laundry franchise companies mainly use barcode recognition-based systems to record laundry consignee information and laundry information for laundry collection management. Conventional laundry collection management systems using barcodes require barcode printing costs, and due to barcode damage and contamination, it is necessary to improve the cost of reprinting the barcode book in its entirety of 1 billion won annually. It is also difficult to do. Recognition performance is improved by applying the VGG model with 7 layers, which is a reduced-transformation of the VGGNet model for number recognition. As a result of the numerical recognition experiment of service parts drawings, the proposed method obtained a significantly improved result over the conventional method with an F1-Score of 0.95.

Purpose The purpose of this study is to measure and analyze the power of the motor-driven transplanter to provide useful information for the optimal design of an electric drive system. Methods An electric transplanter was developed by replacing its engine-driven system with an electric motor-driven system. The data acquisition system was constructed to measure torque and rotational speed data during field operations. The field experiment was performed under three operational conditions at planting distance levels (26, 42, and 63 cm) as follows: (1) driving without transplanting operation, (2) transplanting operation without driving, and (3) transplanting operation with driving. Results In the case of the driving without transplanting operation, the average power requirement of the driving part increased from 0.14 to 0.124 kW. In the case of the transplanting operation without driving, the maximum power requirement of the transplanting part dramatically decreased from 1.084 to 0.346 kW. As the planting distance increased, the average power requirement decreased by 45.7-53.2%. In the case of the transplanting operation with driving and compared to the rated power (3 kW) according to the planting distance, the average total power requirement of the electric transplanter is 1.345 kWat 26 cm (44.8% to rated power), which was approximately 1.57-2.2 times larger than the power requirement at 42 and 63 cm. It can be seen that the continuous operation time is 8.9, 12.8, and 14.3 h at each planting distance. Conclusions The results of this study can provide useful information for designing an optimal electric drive system of a motordriven transplanter considering the load characteristic according to planting distance.

Background: Healthcare workers (HCWs) involved in the care of patients with coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARSCoV- 2) are at risk of being infected. This study aimed to investigate the seropositivity of SARS-CoV-2 among the HCWs. Methods: From June to July 2020, 151 serum samples of HCWs involved in the care of COVID- 19 patients from two hospitals in South Gyeongsang Province, South Korea, were collected to test for the presence of SARS-CoV-2 immunoglobulin G (IgG) antibodies. Epidemiologic data were collected using a questionnaire. Results: Among the 151 HCWs, 3 (2.0%) had detectable SARS-CoV-2 IgG. Two of them were nurses working in the COVID-19 ward of the first hospital and had no direct contact with confirmed COVID-19 patients without personal protective equipment (PPE). The other HCW worked at the infection prevention office and was 6 weeks pregnant at the time of the study. In this study, 19 participants self-reported 33 episodes of contamination during PPE removal, but none of them tested positive. Conclusion: This study reported a seropositivity rate of 2.0% for SARS-CoV-2 IgG among HCWs. Following the exclusion of an HCW with a suspected false-positive result, the adjusted rate was 1.3%, which was higher than that reported at approximately the same time in the community (0.07%). However, there was no evidence of viral transmission among the colleagues of that HCW in this study. Standard precautions, proper monitoring, and PPE use could help prevent the spread of COVID-19 in hospital settings.
