Authors: Rahman Rio Aulia , Chudari Ima Ni’mah 
Published: January 2022

Due to the rampant Covid-19 virus, education is also getting its impact. Teaching and learning activities that are usually carried out in schools have turned into learning from home (BDR) programs. There are new problems faced by students when faced with the BDR program. Guidance and counseling services are assistance programs aimed at students or individuals so that they can overcome the problems they face. Based on research conducted on 6th grade teachers and students, 5th grade teachers and students, 3rd grade teachers and students at SDN 1 Sumurbandung, it was shown that obstacles were found while the teacher provided guidance and counseling services during the BDR program. The research conducted is a qualitative research with a case study method (case study). Data collection techniques used are interviews and documentation studies. Interviews were conducted online using Google Meet or Zoom Meeting media. Based on the data obtained, the teacher provides guidance and counseling services virtually (online) and in person (visiting students' homes). Some of the obstacles faced by teachers were signal problems, many children were found who did not have gadgets, did not have quotas, and excessive parental assistance. Ways that teachers do to overcome these obstacles include providing motivation, communicating with students' parents, doing remedial actions, providing relief from task collection time and providing policies for students who do not have online learning facilities.

Published: January 2022

A continuación, se presentan los resultados del estudio de estimación de los costos de energía eléctrica, obtenidos mediante resultados de laboratorio y corroborados por la simulación de la energía generada a base de hidrógeno, para revisar la factibilidad en el ámbito económico dentro del consumo doméstico de energía eléctrica. Para ello, se realizó el análisis energético del hidrógeno en el mercado, mediante el factor de recuperación (EPBT) el cual nos da como resultado que debe pasar 1.62 años para que una celda de hidrogeno compense la energía que utilizo. De los resultados obtenidos en laboratorio y del modelo matemático en el cual se utilizó una celda de combustible tipo PEM con 46% de eficiencia para que genere 24V, se puede observar la cantidad de energía que se necesita para producir electricidad y el costo de la energía que se produce, la cual es analizada desde el punto de vista energético, técnico y económico, obteniendo así las fortalezas de ser una energía limpia libre de contaminación ya que su único residuo es vapor de agua, pero con la gran desventaja que en el ámbito eléctrico se producen mayores pérdidas de energía debido a la baja eficiencia de las celdas de combustible.

Annotation
Purpose. Improving the mathematical description of the motion of the dynamics of grain motion in the horizontal non-uniform air flow of aerodynamic separators.
Methods. Theoretical determination of the regularities of the plane motion of the grain in an uneven air flow determines the analytical method of research based on the compilation and analysis of the equations of motion of the grains in the form of a sphere in the air flow of the horizontal pneumatic channel of the separator. The mathematical model is formulated by obtaining differential equations of motion of the components of the grain material, which are represented by a material point and a complex indicator of aerodynamic properties – the coefficient of vitality (sail).
Results. The flat motion of the grain in the uneven air flow of the horizontal pneumatic channel of the aerodynamic separator through the sieve surface with cracks in the axial direction of air is absorbed.
The obtained equation of grain motion during horizontal air flow allows to determine the dependence of grain velocity in air-grain medium on a number of factors: geometric parameters of the separator, feed angle, initial kinematic mode of the material, and grain vitality coefficient.
Conclusions
1.	An improved mathematical model of the dynamics of the motion of a solid particle in a horizontal air flow is formulated, which differs from those known in that it reproduces the action of unaccounted factors (non-uniformity of the velocity field, action of lateral forces, material concentration). It is established that the change of the sign of the air flow gradient in the cross section leads to a change in the direction of the trajectories of the light fraction KZM, which increases the completeness of the removal of the feed fraction to 90% and increases the separation of the seed fraction by 15-20%. up to 2-3%. Changing the diagram of the air velocity in the horizontal channel increases the velocity in the wall area, which increases the clarity of the division by 18-24%.
2.	The solution of the system of nonlinear differential equations with initial conditions is performed in the MathCad software environment in the form of grain motion trajectories in horizontal air flow, which allows calculating grain motion trajectories differing in vitality coefficients and determining rational values of pneumatic gravity separators.
Keywords: variable air velocity, trajectory, lateral force, fractions, horizontal air flow, fractionation process, grain.

An analysis on the adjuvant efficacy of intravenous or perineural administered dexamethasone in erector spina plane block applied to patients who had thoracotomy: a prospective randomized double-blind study
Authors: ERTÜRK Tuna , GÜVEN Bülent Barış , ERSOY Aysin 
Published: January 2022

Aim: Thoracic surgery is one of the surgical procedures that necessitates effective pain management both before and after the procedure. Because of the adverse effects of opioids in thoracic surgeries, regional anesthesia has been widely used for postoperative analgesia. One of the most recent techniques used with this indication is erector spina plane block (ESPB). Many studies in regional anesthesia have shown that adding dexamethasone to local anesthetics as an adjuvant agent prolongs the analgesic effect. The purpose of the present study was to assess the effect of dexamethasone, which is used as a perineural and intravenous adjuvant, on the duration and level of analgesia of ESPB used in thoracic surgeries.
Material and Method: This prospective, randomized controlled study included 60 patients who would have a thoracotomy under general anesthesia and ESP for peri-operative analgesia. Patients were divided into three groups: those who received perineural dexamethasone (Group PN), those who received IV dexamethasone (Group IV), and those who did not receive any dexamethasone at all (Group C-Control). Numerical rating scale (NRS) scores, rescue analgesic drug use and block times were recorded at the postoperative 2nd, 6th, 12th, 24th and 36th hours.
Results: There was no statistically significant (p>0.05) difference in blocking times or additional analgesic use between the three groups. There was no statistically significant (p>0.05) difference in the NRS scores when the patients’ pain levels were measured in all three groups. 36th hour NRS scores and additional analgesic use were higher in the group that did not receive IV or perineural dexamethasone.
Conclusion: NRS scores and rescue analgesic use were similar between ESPB groups with intravenous or perineural addition of 4 mg dexamethasone and ESPB group administered without dexamethasone. However, the NRS score average in the group C was greater than 3, particularly in the 36th hour NRS data, whereas the NRS scores in the group PN and group IV were less than 2.
Anesthesia management in geriatric patients which were interventional bronchoscopy due to central airway obstruction; retrospective analysis
Authors: ZENGİN Musa , BALDEMİR Ramazan 
Published: January 2022

Aim: In the endobronchial treatment of tumors that cause obstruction in the tracheobronchial system; Applications such as cryo-recanalization and argon plasma coagulation (APC) are widely used. Patients presenting with central airway obstruction (CAO) require urgent intervention, sharing the airway with the bronchoscopist, severe shortness of breath in patients, and the presence of comorbid diseases make it difficult for anesthetists. This situation becomes more complicated due to pharmacokinetic and pharmacodynamic changes in geriatric patients. In this article, it is aimed to present the anesthesia method in geriatric patients who underwent interventional bronchoscopy due to central airway obstruction.
Material and Method: The files of geriatric patients who underwent interventional procedures for central airway obstruction between January 2021 and September 2021 were reviewed retrospectively. The treatments applied to the patients and the applied anesthetic protocols were recorded.
Results: Forty-five geriatric patients who underwent interventional procedures for CAO were identified. 74% of the patients were male. 95.6% of the patients were in the American Society of Anesthesiologists (ASA) III or ASA IV risk group, which we can refer to as the high risk group. It was observed that rapid and short-acting propofol and remifentanil were used in induction and maintenance of anesthesia, rocuronium was used as muscle relaxant, and sugammadex was used to eliminate the residual effect of the muscle relaxant.
Conclusion: Airway management is very complex in severe life-threatening airway stenosis. This situation requires a more comprehensive preoperative evaluation, selection of appropriate short-acting anesthetics, and effective anesthetic monitoring, especially in geriatric patients. In addition, the anesthetist and bronchoscopist should be prepared and in constant communication against complications that may develop.

Published: January 2022

Aim: Thymic measurements should be interpreted relative to normal measurement values according to age groups and gender. Thymic gland measurement may vary between radiologists. In our study we wanted to determine the interobserver variability of thymic size measurements on CT by comparing volumetric calculations to commonly used bidimensional measurements.
Material and Method: The chest CT scans of 156 patients who had any oncological problems or disorders influencing the thymic size were retrospectively evaluated. The shape (quadrilateral or triangular), anteroposterior (AP) and transverse (TR) diameters, as well as the thickness of each lobe and thymus volume were measured independently by two radiologists. Interobserver variability was determined according to these parameters by Pearson correlation test.
Results: The shape of the thymic gland was triangular in 72% (n:113) and quadrilateral in 28% (n: 43) of all subjects. According to the results of the correlation test, a moderate relationship in terms of AP length, a weak relationship in terms of TR length, a negligible relationship in terms of right lobe thickness and a weak relationship in terms of left lobe thickness were obtained, but a very strong relationship was found between the two radiologists for volumetric measurements.
Conclusions: Volumetric measurements can be used as a basis for thymic imaging, reducing the differences among radiologists, and unnecessary and advanced examinations can be avoided.

Published: January 2022

Aim: Thoracotomy is among the most painful surgical incisions and causes severe acute pain in the postoperative period. Many analgesic methods have been suggested for thoracotomy pain treatment. Thoracic epidural analgesia (TEA) and thoracic paravertebral block (TPVB) are common regional methods for post-thoracotomy pain. In this study, we aimed to compare the efficacy and the side effects of TEA and TPVB methods applied for post-thoracotomy analgesia.
Material and Method: After ethical committee approval, we retrospectively analyzed postoperative analgesia records of patients, who underwent thoracotomy, received TEA or TPVB for postoperative analgesia between 01.01.2019 and 01.01.2021. Visual analog scale (VAS) scores of the patients who received analgesic treatment for 24 hours postoperatively after TEA or TPVB application were evaluated.
Results: Data of 474 patients were found eligible for analysis. Demographic data of patients, VAS scores, patient satisfaction, and additional analgesic requirements were not statistically significant between the groups (p>0.05). Nausea-vomiting, hypotension, headache, itching, and sweating was statistically significantly higher in the TEA group when compared to patients who underwent TPVB (p
