ESP Learners Pronounce in New Trend (You Tube) Application: Instructor's Perception and Practice

The aim of teaching English for Specific Purposes (ESP) is not to imitate the native speakers or to develop the British or American accents. English communication influences the first language or mother tongue for ESP learners. Meanwhile, According to Evan (1997), ESP has some characteristics, such as: firstly, ESP may be related or designed for specific disciplines, secondly, ESP may be used in specific teaching situations and has different methodology from that of General English (GE); thirdly, ESP is likely to be designed for adult learners, either at a tertiary level education or in a professional work situation; fourthly, most ESP courses take on some basic knowledge of the language systems. This research used descriptive qualitative research as a design to gather or collect the data because of the current phenomenon to explain the error of pronunciation and the causes of error in pronouncing words. This paper will be done by researchers at Management Class who learn the ESP program in Kaltara University. This research also used observation field notes and interview guide as the instruments. Hence, the researchers found that there were fifteen pronunciation errors who were presented by ESP learners’ mother tongue in learning speaking through YouTube Application. Besides, there were four materials in You Tube Application that pronounced by ESP Learners such as: Promotion, Bargaining, Complaining, and Response.

Pleural complications in patients with coronavirus disease 2019 (COVID-19): how to safely apply and follow-up with a chest tube during the pandemic?

OBJECTIVES Severe acute respiratory syndrome coronavirus 2, a novel coronavirus, affects mainly the pulmonary parenchyma and produces significant morbidity and mortality. During the pandemic, several complications have been shown to be associated with coronavirus disease 2019 (COVID-19). Our goal was to present a series of patients with COVID-19 who underwent chest tube placements due to the development of pleural complications and to make suggestions for the insertion and follow-up management of the chest tube. METHODS We retrospectively collected and analysed data on patients with laboratory-confirmed COVID-19 in our hospital between 11 March and 15 May 2020. Patients from this patient group who developed pleural complications requiring chest tube insertion were included in the study. RESULTS A total of 542 patients who were suspected of having COVID-19 were hospitalized. The presence of severe acute respiratory syndrome coronavirus 2 was confirmed with laboratory tests in 342 patients between 11 March and 15 May 2020 in our centre. A chest tube was used in 13 (3.8%) of these patients. A high-efficiency particulate air filter mounted double-bottle technique was used to prevent viral transmission. CONCLUSIONS In patients with COVID-19, the chest tube can be applied in cases with disease or treatment-related pleural complications. Our case series comprised a small group of patients, which is one of its limitations. Still, our main goal was to present our experience with patients with pleural complications and describe a new drainage technique to prevent viral transmission during chest tube application and follow-up.

Flow behavior analysis of confined fluid in a flexible tube: application of asymptotic approach

In this paper, we asymptotically investigate a confined fluid flow in a flexible tube with a variable section. The fluid is considered to be newtonian, incompressible and it elapses in elastic and isotropic shell. This study provides a review of recent analysing the effects of the elastic wall tube properties over the fluid behaviour. The unsteady fluid flow will be analysed following the singular perturbations theory according to a large Reynolds number and a small aspect radio. The wall is assumed to be a thin shell that generate a small axisymmetric vibration. This model is mathematically developed by using the thin shell linear theory that is governed by a geodesic curvature parameter.
