Le paradoxe de la politique
Authors: Bruyeron Roger
Published: September 2022

Vladimir Jankélévitch prétend qu’il n’a pas écrit une philosophie politique à la mesure de son engagement politique. Il semble bien qu’il en soit ainsi et rares sont les commentateurs de son œuvre qui ont traité de cet aspect de sa pensée. Le but de cette réflexion est de tenter de mettre fin à ce jugement en reprenant des analyses éparses qui forment en réalité une pensée politique précise et forte. Le philosophe a pris des positions, a affirmé des principes qui, selon nous, déterminent une pensée paradoxale de la politique, une pensée politique qui secrète en elle sa propre contradiction, ce que l’auteur a nommé le déchirement. En reprenant une expression de G. Simmel, nous soutiendrons que la pensée politique de V. Jankélévitch exprime la tragédie de la politique.
Pour sortir de l’impasse
Authors: Jappe Anselm
Published: September 2022

Matériau de construction favori du capitalisme, le béton apparaît comme le symbole d’une logique destructrice, qui enlaidit et uniformise le monde tout en épuisant ses ressources. Anselm Jappe rebondit sur son dernier essai, Béton. Arme de construction massive du capitalisme (L’Échappée, 2020), pour dessiner les contours d’une nouvelle architecture heureuse. Celle-ci s’appuie autant sur l’urbanisme poétique et ludique de l’utopie situationniste de Guy Debord, dont il est spécialiste, que sur la puissance créative émanant de l’intelligence collective qui a façonné des architectures éblouissantes, comme sur le littoral méditerranéen.

Alors que l’élevage et l’abattage industriels scandalisent de plus en plus de citoyens, Jocelyne Porcher revient sur les origines de l’exploitation de masse des animaux de ferme. La directrice de recherche à l’Institut national de la recherche agronomique (Inrae) démontre que, loin d’être une dérive, l’atrocité de leur traitement est constitutive de l’apparition de la zootechnie, qui réduit ces bêtes au rang d’objets soumis à des impératifs industriels. S’élevant contre cette exploitation et son nouvel avatar progressiste qu’est l’agriculture cellulaire, elle appelle à sortir de cette relation pathologique aux animaux de ferme grâce à un retour à l’élevage paysan.

Published: September 2022

The World Health Organization declared the Coronavirus Diseases 2019 (COVID-19) outbreak a global pandemic on March 11, 2020. COVID-19 had an impact on over 500 million people worldwide. According to the American Thoracic Society criteria, the respiratory spectrum of this disease ranges from mild illness to severe pneumonia, with the latter occurring in a not insignificant 15% of patients. A rapid increase in the incidence of COVID-19 pneumonia cases has been observed all over the world, resulting in a saturation of the Intensive Care Unit's capacity (ICUs). Because of this impressive outbreak, the ICU beds and invasive mechanical ventilators reached their capacity. Non-invasive supportive care has become an important option for keeping respiratory conditions under control. As a result, proper healthcare resource management was required to ensure adequate patient care. Respiratory Intensive Care Units (RICUs) have become a useful resource for managing complex patients due to a shortage of ICU capacity. This highlighted the importance of RICUs, where patients with moderate to severe respiratory failure can be treated with non-invasive respiratory support rather than being admitted to the ICU. The clinical outcomes and baseline characteristics of patients admitted to the RICU of Cotugno Hospital, a tertiary referral center in Naples (Italy), from January 2021 to October 2021 are described in this report.
What's new in neuromyelitis optica spectrum disorder treatment?
Authors: Chu Yi-Ching , Huang Tzu-Lun
Published: September 2022

Optic neuritis, an optic nerve inflammatory disease presenting with acute unilateral or bilateral visual loss, is one of the core symptoms of neuromyelitis optica spectrum disorder (NMOSD). The diagnosis of NMOSD-related optic neuritis is challenging, and it is mainly based on clinical presentation, optical coherence tomography, magnetic resonance imaging scans, and the status of serum aquaporin-4 antibodies. In the pathogenesis, aquaporin-4 antibodies target astrocytes in the optic nerves, spinal cord and some specific regions of the brain eliciting a devastating autoimmune response. Current pharmacological interventions are directed against various steps within the immunological response, notably the terminal complement system, B-cells, and the pro-inflammatory cytokine Interleukin 6 (IL6). Conventional maintenance therapies were off-label uses of the unspecific immunosuppressants azathioprine and mycophenolate mofetil as well as the CD20 specific antibody rituximab and the IL6 receptor specific antibody tocilizumab. Recently, four phase III clinical trials demonstrated the safety and efficacy of the three novel biologics eculizumab, inebilizumab, and satralizumab. These monoclonal antibodies are directed against the complement system, CD19 B-cells and the IL6 receptor, respectively. All three have been approved for NMOSD in the US and several other countries worldwide and thus provide convincing treatment options.

Published: September 2022

Introduction:

In this study, we prospectively investigated changes in serum interleukin-6 (IL-6), high-sensitivity C-reactive protein (hsCRP) and full white blood cell (WBC) counts during the diagnosis and treatment of paediatric patients with appendicitis. We also investigated the effects of the COVID-19 pandemic on the diagnosis and treatment processes of paediatric appendicitis patients.

Materials and Methods:

A non-perforated appendicitis group (n = 110), a perforated appendicitis group (n = 35) and an appendicitis + COVID-19 group (n = 8) were formed. Blood samples were taken upon admission and every day until the three studied parameters returned to normal values. To investigate the effects of the COVID-19 pandemic on paediatric appendicitis patients, the perforated appendicitis rates and the times from the onset of the first symptoms to the operation before and during the pandemic were compared.

Results:

WBC, IL-6, and hsCRP dropped below the upper limits on the second postoperative day in the non-perforated appendicitis group, four to six days postoperatively in the perforated appendicitis group, and three to six days postoperatively in the appendicitis + COVID-19 group. These parameters were not within normal range in patients who developed complications during follow-up. The time from the onset of abdominal pain to the surgery was significantly longer during than before the pandemic in both the non-perforated appendicitis group and the perforated appendicitis group.

Conclusions:

Our results show that WBC, IL-6, and hsCRP are useful laboratory parameters that can complete clinical examinations in the diagnosis of appendicitis in paediatric patients and the identification of complications that may develop postoperatively.
What's best, online or on-site? The write a scientific paper course
Authors: Grech Victor , Myatt Jeremy Borg , Cuschieri Sarah
Published: September 2022

Background:

The ability to publish is a career-critical skill but requires the acquisition of a wide and disparate skill set. The Write a Scientific Paper (WASP) course was created in Malta in 2010, an intensive, three-day event. WASP is an accredited event held in Malta, London, and Bahrain. The COVID pandemic forced WASP to go online. This study compared satisfaction with WASP online as opposed to in-person by analyzing course feedback pre- and post-pandemic.

Methods:

Google forms are used to collect anonymous feedback on a Likert scale for various aspects of each WASP. The period 2017 to 2022 was used to compare four courses on-site and five courses online. Feedback on: Rate lectures, handouts, WASP overall and how likely are you to recommend WASP was compared.

Results:

Response rates were >60% and almost all Cronbach's Alpha values were >0.7. High satisfaction scores were achieved in all four questions (>4/5). There were no significant differences except in lectures, which scored well but fared slightly worse overall online.

Conclusions:

Migrating online does not necessarily lead to change/s in presentation contents but transforms delivery. Our results indicate that WASP is accepted online but the slightly lower lectures score implies that WASP might be better delivered in-person than online. However, students remained happy to recommend WASP and this accords with other studies that overall, student satisfaction with online education is common. It is hoped that as the pandemic recedes, webinars complement and not continue to totally replace traditional in-person meetings.
Feasibility of intraoperative quantitative neuromuscular blockade monitoring in children using electromyography
Authors: Owusu-Bediako Kwaku , Munch Ryan , Mathias Jay , Tobias Joseph D.
Published: September 2022

Background:

Quantitative train-of-four (TOF) monitoring remains essential in optimizing anesthetic outcomes by assessing the depth and recovery from neuromuscular blockade. Despite this, residual neuromuscular blockade, defined as a TOF ratio <0.90, remains a concern in both adult and pediatric patients. Quantitative TOF monitoring has seen limited use in infants and children primarily due to a lack of effective equipment. This study evaluates a new electromyography (EMG)-based TOF monitor in pediatric patients undergoing inpatient surgical procedures including laparoscopic (restricted arm access) surgery.

Methods:

Pediatric patients undergoing inpatient surgery requiring the administration of neuromuscular blocking agents (NMBAs) were enrolled. The EMG electrodes were placed along the ulnar nerve on the volar aspect of the arm to provide neurostimulation. The muscle action potentials from the abductor digiti minimi muscle were recorded. Neuromuscular responses were recorded by the device throughout surgery at 20-s intervals until after tracheal extubation. Data recorded on the monitor's built-in memory card were later retrieved and analyzed.

Results:

The study cohort included 100 pediatric patients (62% male). The average age was 11 years (IQR: 8, 13) and the average weight was 39.6 kg (30, 48.7). Automatic detection of supramaximal stimulus was obtained in 95% of patients. The muscle action potential mean baseline amplitude (in mV) was 7.5 mV (6, 9.2). The baseline TOF ratio was 100% (100, 104). After administration of a neuromuscular blocking agent, monitoring of the TOF ratio was successful in 93% of the patients. After antagonism of neuromuscular blockade, monitoring was possible in 94% of patients when using an upgraded algorithm. The baseline amplitude recovered to 6.5 mV (5, 7.8), and the TOF ratio recovered to a mean of 90.1% (90,97) before tracheal extubation.

Conclusion:

Our results indicate that neuromuscular monitoring can be performed intraoperatively in pediatric patients weighing between 20 and 60 kg using the new commercially available EMG-based monitor. Automatic detection of neuromuscular stimulating parameters (supramaximal current intensity level and baseline amplitude of the muscle action potential) by an adult neuromuscular monitor is feasible in pediatric patients receiving nondepolarizing neuromuscular blocking agents.
Effect of two different levels of positive end-expiratory pressure (PEEP) on oxygenation and ventilation during pneumoperitoneum for laparoscopic surgery in children
Authors: Bhardwaj Neerja , Sarkar Soumya , Yaddanapudi Sandhya , Jain Divya
Published: September 2022

Background:

Positive end-expiratory pressure (PEEP) is used to attenuate the changes in respiratory parameters because of pneumoperitoneum during laparoscopic (LAP) surgery. As the ideal level of PEEP during LAP in children is not known, this study compared the effect of 5- and 10–cm H2O of PEEP on oxygenation, ventilator, and hemodynamic parameters during pediatric LAP.

Method:

After obtaining approval from the Institute Ethics Committee and written informed parental consent, 30 American Society of Anesthesiologists (ASA) I and II children aged 2–10 years, undergoing LAP were randomized to receive PEEP of 5- or 10–cm H2O during pneumoperitoneum. Baseline hemodynamic and ventilatory parameters, PaO2, and PaCO2 were measured 2 min after tracheal intubation, 2 min and 1 h after pneumoperitoneum, and after deflation of pneumoperitoneum. Oxygenation index, dynamic compliance, and alveolar-arterial oxygen gradient (D (A-a) O2) were calculated at the above-mentioned time points. Data were analyzed using Student's t-test and repeated measures ANOVA with Bonferroni correction.

Results:

The oxygenation index and D(A-a)O2 decreased in PEEP 5 Group and increased in PEEP 10 Group after pneumoperitoneum, the difference between the two groups being statistically significant (P = 0.001). The dynamic compliance decreased in PEEP 5 Group and increased or remained the same in PEEP 10 Group after pneumoperitoneum, the difference between the two groups being significant (P = 0.001). There were no significant changes in the hemodynamic parameters in the two groups.

Conclusion:

Use of 10-cm H2O PEEP during pneumoperitoneum in children improves ventilation and oxygenation, without significant hemodynamic changes.
Major depressive disorder (MDD), antidepressants, and uncontrolled hypertension
Authors: Paraskeva Anteia , Theodosopoulou Polyxeni
Published: September 2022

Objective:

Major depressive disorder (MDD) represents the leading cause of mental disability worldwide. While relations between MDD and alterations to the cardiovascular system have been studied before, the autonomic dysfunction caused by the disease and the medical therapies involved during treatment has not been widely reported. Our case aims to prove such linkage exists and is a potent hazard during major operative procedures.

Methods:

Studies have associated the disorder with a concomitant dysfunction of the autonomic nervous system, predisposing patients to hypertension. We present the case of a patient presenting with an intraoperative hypertensive spike that could be attributed to such a dysregulation of the autonomic system, in the absence of any other possible explanation.

Results:

The observed intraoperative hypertensive spike was managed pharmacologically, and the patient did not experience any further hemodynamic instability or postoperative complications.

Conclusion:

Our case tries to highlight a disregarded aspect of perioperative management for patients suffering from MDD.
Low-dose spinal block combined with epidural volume extension in a high-risk cardiac patient
Authors: Almeida Carlos R. , Vieira Ligia S. , Cunha Pedro , Gomes Ana
Published: September 2022

Background:

Anesthetic management of patients with severe cardiac disease can be challenging during prolonged surgical procedures. Thus, alternative neuraxial anesthetic techniques have been described to avoid general anesthesia in these patients.

Methods:

A case-based systematic literature review on low-dose spinal block combined with different methods of epidural block extension in high-risk cardiac patients was performed.

Results:

We describe the successful management of a patient with poor left ventricular function who underwent excision arthroplasty of an infected hip prosthesis under low-dose spinal block with levobupivacaine 5 mg and fentanyl 15 μg combined with saline epidural volume extension (EVE). Epidural ropivacaine 0.75% was administered as a bolus of 5 ml followed by an infusion at 5 ml/h later during the course of surgery.

Conclusions:

Although continuous spinal anesthesia (CSA) or epidural anesthesia may limit hemodynamic instability, the possibility of devastating central nervous system infection may prevent CSA use, and epidural block alone may be less reliable than CSA. Epidural block alone may require large volumes of concentrated local anesthetic to obtain sacral block, which may produce hemodynamic instability. The EVE, particularly using saline EVE, has rarely been described in high-risk cardiac patients as an alternative to CSA or epidural block alone, with the intention to avoid general anesthesia, but it has demonstrated efficacy and a low rate of complications. Hemodynamic stability was maintained in most cases.

Published: September 2022

Postoperative myoclonic movement (PMM) is an uncommon side effect after general anesthesia (GA), and the exact cause of this neurologic complication is still unknown. Many factors such as anesthesia, psychological stresses, and surgical stress could trigger PMM. We are here reporting a case of PMM in the post-anesthetic care unit (PACU) following general anesthesia in an apparently healthy patient.
Rodent models of senile normal-pressure hydrocephalus
Authors: Chen Li-Jin , Tsai Sheng-Tzung , Tseng Guo-Fang
Published: September 2022

Cerebrospinal fluid (CSF) and its drainage are crucial in clearing metabolic waste and maintaining the microenvironment of the central nervous system for proper functioning. Normal-pressure hydrocephalus (NPH) is a serious neurological disorder of the elderly with obstruction of CSF flow outside the cerebral ventricles, causing ventriculomegaly. The stasis of CSF in NPH compromises brain functioning. Although treatable, often with shunt implantation for drainage, the outcome depends highly on early diagnosis, which, however, is challenging. The initial symptoms of NPH are hard to be aware of and the complete symptoms overlap with those of other neurological diseases. Ventriculomegaly is not specific to NPH as well. The lack of knowledge on the initial stages in its development and throughout its progression further deters early diagnosis. Thus, we are in dire need for an appropriate animal model for researches into a more thorough understanding of its development and pathophysiology so that we can enhance the diagnosis and therapeutic strategies to improve the prognosis of NPH following treatment. With this, we review the few currently available experimental rodent NPH models for these animals are smaller in sizes, easier in maintenance, and having a rapid life cycle. Among these, a parietal convexity subarachnoid space kaolin injection adult rat model appears promising as it shows a slow onset of ventriculomegaly in association with cognitive and motor disabilities resembling the elderly NPH in humans.

Published: September 2022

Objectives:

Tuberculosis (TB) of lymph node (TB lymphadenitis) is one of the most common forms of extrapulmonary TB (EPTB) whose diagnosis is critically challenging. Although new diagnostic methods have been developed, especially in patients without a history of TB, the cervical tuberculous lymphadenitis diagnosis is still elusive. This study assessed the applicability of GeneXpert in early diagnosis of EPTB, especially cervical lymphadenopathy.

Materials and Methods:

The study was conducted in a tertiary care hospital from January 2018 to December 2020 at the department of microbiology. All the samples of cervical lymph node tissue and lymph node aspirate were followed as per the routine protocol for mycobacterial identification. The sample was divided into two parts: one was used for the new molecular-based GeneXpert MTB/RIF assay and the second one was tested by direct and concentrated acid-fast bacilli microscopy by Z-N staining and culture for the detection of MTB.

Results:

Among the 145 samples tested, the GeneXpert detected the DNA of MTB in 89 samples (61.37%), whereas the culture test was positive in 42 (28.93%) specimens. GeneXpert also detected 7 rifampicin resistance cases. GeneXpert sensitivity and specificity results were assessed according to culture results. The sensitivity and specificity of the GeneXpert assay were 85.71% and 48.54%, respectively.

Conclusion:

GeneXpert MTB/RIF should be used in conjunction with clinical presentation and other molecular investigation in nonrespiratory specimens.
Frequency and parameters of linkage disequilibrium of the two-locus HLA-B~MICA haplotypes in russians from chelyabinsk region
Authors: Vavilov Mikhail N. , Suslova Tatiana A. , Burmistrova Aleksandra L.
Published: September 2022

MICA gene is located in the MHC region on chromosome 6p21.33, mapped ca. 46.4 kb centromeric to the HLA-B gene, being in strict linkage disequilibrium with MHC class I region. The sufficient polymorphism of human MICA gene and its location at the HLA region makes it a likely candidate locus for additional histocompatibility testing. The data on distribution of two-locus HLA-B~MICA haplotypes enable us to obtain information about the level of mismatches in the MICA locus when selecting suitable donor-recipient pair by convential HLA loci for unrelated hematopoietic stem cell transplantation. We have performed immunogenetic typing of 100 donors of Russian Nationality from the Register of Stem Cell Donors at Chelyabinsk Regional Blood Bank. MICA genotyping was carried out by PCR tests with sequence-specific primers at basic resolution. Typing of the classical HLA-B locus was carried out by the NGS method using MiSeq instrument using a MiSeq v2 reagent kit (Illumina). Linkage disequilibrium indices D, D`, p, and the frequency of two-locus HLA-B~MICA haplotypes were calculated using Arlequin 3.5 software. As a result of this study, the main parameters of linkage disequilibrium and the frequency of two-locus HLA-B~MICA haplotypes were established for Russians from the Chelyabinsk region. HLA-B allelic groups have been identified that form stable pairs with specific MICA allelic variants (HLA-B*B*07, B*08, B*13, B*14, B* 27, B*37, B*38, B*47, B *48, B*49, B*50, B*52, B*55, B*56, B*57). Moreover, we have revealed HLA-B allelic groups forming highly variable HLA-B~MICA haplotypes (HLA-B*15, B*18, B*35, B*39, B*40, B*41, B*44 and B*51) with increased risk of mismatch for MICA genes. These results could be used in clinical practice in order to assess probability of the donor/recipient mismatch for non-classic MICA locus when selecting potential stem cell donors for hematological patients by HLA testing of classical loci. Moreover, these data could be demanded in population genetics.

The museum exhibition in the context of dispositive analysis
Authors: Kolaříková Veronika
Published: September 2022

The aim of this study is to propose and present a suitable methodological framework based on the principle of discourse analysis, which would be suitable for the implementation of research on the museum environment, in particular museum exhibitions and their narratives. The potential of the dispositive analysis of the museum phenomenon is enormous, but the elaboration of this methodology in the context of museum research in our environment is lacking. This study aims to add to this underdeveloped area and provide readers and researchers with key information concerning the possibilities and uses of this methodology. As a suitable methodological tool, the study chooses dispositive analysis, which has the advantage of allowing the analysis of materializations in addition to the discourse plane, which is an advantage for the analysis of exhibitions and the exhibits housed therein. Dispositive analysis, which in the study is primarily based on S. Jäger’s approach, enables the examination of materializations without overlooking the role of visitors and the broader context of the exhibition, which, by its very nature of membership of a cultural institution, is always discursively conditioned. The relationship between the museum and discursive reality is thus a thematic part of the study, as is the exploration of the topics of discourse (Foucault) and the dispositive.

Published: September 2022

Antiques usually require careful handling, so these objects cannot be made available to the general public and are handled only by restoration specialists. This article focuses on the preservation of antiquities in terms of cultural heritage and the availability of these objects for access by visitors, it describes and evaluates the development of a method to support the digitisation of objects considered solids of revolution. The artifacts were provided by the Museu Joaquim José Felizardo in the city of Porto Alegre, Brazil, and were used to set the table in the former Confeitaria Rocco (bakery). The 3D process consisted of the following steps: laser scanning, data processing of the coordinates obtained from the surface of the object into point clouds, creation of the virtual model, creation of a physical model using additive manufacturing, and evaluation of the physical model in comparison with the original artifact. The obtained results show that highly accurate models can be created using the proposed method. Therefore, virtual data can be obtained for the conservation, restoration and creation of replicas for studies and accessibility.
Counterexample-Guided Prophecy for Model Checking Modulo the Theory of Arrays
Authors: Mann Makai , Irfan Ahmed , Griggio Alberto , Padon Oded , Barrett Clark
Published: September 2022

We develop a framework for model checking infinite-state systems by
automatically augmenting them with auxiliary variables, enabling
quantifier-free induction proofs for systems that would otherwise require
quantified invariants. We combine this mechanism with a counterexample-guided
abstraction refinement scheme for the theory of arrays. Our framework can thus,
in many cases, reduce inductive reasoning with quantifiers and arrays to
quantifier-free and array-free reasoning. We evaluate the approach on a wide
set of benchmarks from the literature. The results show that our implementation
often outperforms state-of-the-art tools, demonstrating its practical
potential.

Both Unmanned Aerial Vehicles (UAVs) and Terrestrial Laser Scanners (TLS) are important techniques for surveying and mapping. UAV equipment is commonly used to collect 2D or 3D data acquisition. Meanwhile, TLS equipment is used for obtaining only 3D data acquisition. However, if both are integrated, they were able to produce more accurate data. Multi-sensor data fusion helps overcome the limitations of a single sensor and enables a complete 3D model for the structure and better object classification. This study focuses on studying the combination of UAV and TLS technologies to collect, process data, and create the complete point cloud between two point clouds of the high building in Ha Long city, Quang Ninh province to establish a 3D model at LoD 3 detail level, with high accuracy. FARO FOCUS3D X130 and DJI Phantom 4 RTK equipments were used to acquire the data in the field. The aerial and ground data were processed using FARO SCENE 2019 and Agisoft PhotoScan software, respectively. The data integration process is done by converting both point clouds into the same coordinate system and then by aligning the same points of both points clouds in Cloud Compare. The result of this study is a 3D model at LoD 3 detail level of the high building based on the point cloud accuracy in centimeter level. The combined use of UAV and TLS technologies has proven to be possible to create a highly accurate 3D model, at the 1:500 scale of urban areas according to current standards.

The Chu Lai granitogneiss is widespread throught the Northern Kontum massif. The Chu Lai body is located in the W-SW of the Nui Thanh Townlet (Nui Thanh Dists., Quang Nam Prov.). On an areas of ~ 300 km2. The Chu Lai intrusion mainly consists two mica gneiss, it is light grey and have porphyritic textures. Its major minerals include plagioclase (25÷40%), K-feldpar (20÷40%), quartz (25÷35%), biotite (5÷13%) and mustcovite (0÷6%). Accessory minerals are apatite, zircon, orthit. Garnet and tourmaline are occiasionally found. Zircons separated from a granitogneiss sample colleted in Chu Lai body are generally euhedral to subhedral, dark gray and prissmatic in shape with 100÷300 µm, with length/witdth ratios from 1:1÷1:3. There are many Neoproterozoic - Cambrian ages among the zircon cores in the Chu Lai samples, and these are regarded as inherited zircons. The LA-ICP-MS zircon age is 431 Ma, corresponding to the Silurian. The Chu Lai granitogneiss strongly negative zircon εHf (-4.2÷-11.4) and complex inherited zircon components, characteristics of typical S-type granite. Hf model ages TDM2 1.5÷1.9 Ga, suggests that the Chu Lai granitogneiss was derived from partial melting of old crustal basement rocks, probaly Paleoproterozoic in age.

Marine industry is one of the strong sectors bringing great economic benefits in the world and especially in Vietnam. However, the control of marine aquatic environment is always a complicated problem in both solutions and implementation. Currently, monitoring systems are capable of measuring most of the indicators but still face many difficulties with special indicators such as NH3, H2S, which need to integrate many specialized equipment applications, complex measurement procedures, or waiting for results from a laboratory. Therefore, the implementation is hindered and increases the investment cost. In this article, the authors apply an indirect measurement method to determine the rate of ammonia (NH3) for an automatic monitoring system of the aquatic environment. The monitoring system will monitor the basic water indicators in the National technical regulation on aquaculture water including temperature, salinity, pH, and based on that to calculate and determine the distribution rate of NH3 – factor major cause of losses in the marine products industry. The application of this indirect measurement method aims to directly assess the fluctuation of the Ammonia NH3 index and contribute to the reduction of aquatic environmental monitoring models.

Published: September 2022

The influence between the diverse learning variables affecting the academic achievement of learners according to class types should be studied extensively for the effectiveness of the Korean online general English classroom. Therefore, within the overall online non face-to-face class situation due to the prolonged COVID-19 pandemic, for 15 weeks 80 Korean university students experienced general English classes according to the non face-to-face class format. The purpose of this study was to investigate learner interactions (student-to-student vs. student-to-instructor), their motivation and satisfaction levels, and their English speaking achievement with a particular focus on lecture types (real-time Zoom classes vs. video-recorded classes). In addition, learning variables which can affect English speaking achievement and satisfaction were measured using a survey. By studying these variables, which have been insufficient so far, the intention was to provide some implications for the effective online class operation for the university general English classroom.
Correlation analysis, t-test, and multiple linear regression were conducted, and the results were as follows: First, students’ interaction and academic achievements showed significant correlation and student-to-student and student-to-instructor interactions showed significant correlation. However, there was not any significant correlation between student-to-student interaction and their English speaking achievement. Second, significantly different lecture types had an impact on student interactions, their learning motivation, and academic achievements, but not on their level of satisfaction. Third, there were not any significant variables affecting course satisfaction, and student-to-instructor and student-to-student interactions had a significant effect on academic achievement. The 54.4% of English speaking achievement is explained through student-to-instructor and studentto-student interactions.
Therefore, lecturers should take into regard the students’ diverse learning related-variables, which can affect the online English speaking class, and try to enhance the students’ satisfaction, motivation, and interaction levels. By doing so, we hope to maximize the educational effect of the online English speaking classes.

Published: September 2022

This study aims to figure out the relationship between writing competence and grammatical knowledge. Recently, the importance of practical English competence has been emphasized more and more, and we can see a movement towards the improvement of English writing skills. Compared to other language skills, writing has not been given much attention by instructors because giving writing instructions is not easy, and the assessment of writing is also not a simple process. Therefore, learners have not had many opportunities for practicing their writing skills. When it comes to writing, learners need to generate ideas, organize their thoughts, choose the proper vocabulary, and complete the writing assignment with coherence. In addition, there are many aspects of writing such as spelling, mechanics, organization and content. Learners are required to master various characteristics of writing to complete their essay. Among those factors, learners have difficulty in applying grammatical rules, leading to a lack of motivation for writing. Therefore, the objective of this study is to highlight the relationship between writing competence and grammatical knowledge through correlation analysis. For the study, 108 students who took a writing course at university were asked to take a grammar test, and they completed ten writing activities over the course of one semester. An analysis of correlation was conducted using SPSS 21 Version and further discussion was introduced.

Authors: Jones Stuart , Richards Andrew
Published: September 2022

This study investigated how EFL teachers at a Korean university perceived the introduction of post COVID restrictions and protocols during their classes during the transition from online classes to in-person classes in the spring of 2022. Data were collected from 17 teachers employed at a private university in the greater Seoul area. A survey questionnaire consisting of multiple choice, Likert scale and open-ended questions was used as the initial data collection method. In addition, survey participants who consented were contacted by e-mail to discuss responses in greater detail. Data was analyzed using general qualitative analysis and discussed using descriptive statistics. The findings show that despite the restrictions, teachers were generally able to continue their teaching duties but there were high levels of frustration with the limited number of pedagogical options available to them. In addition, they view masks and socially distancing as a significant hindrance to communication, classroom engagement, and performance. Administrational and educational implications of these findings as well as limitations are also discussed.

Organic junk contamination is one of the serious environmental concerns throughout today’s world. Heavy usage of throwaway plastics devastates nature by obstructing rainwater drainage. From constant exposure to sunlight and warmth, plastics release hazardous gasses into the atmosphere. To reflect the vastly increased amount of various waste plastics, a scaled hybrid plasma gasification reactor is being introduced, which uses an advanced pyrolysis process to break down the plastic waste. The design is simple, transportable, easy to handle, and required very little repair work on long-period usage. Thermochemical investigations are carried out at temperatures ranging from 400 to 600 degrees Celsius, with heating rates ranging from 15 to 22 degrees Celsius per minute, yielding 76-88 percent pyrolysis oil, 10-23 percent syngas, and 4-15 percent chars as besides. It occurs when the molecular architecture of polymers is separated, resulting in the creation of Synthesis gas, which is then condensed into synthesis petroleum fuel. The highest yielding of oil utilizes gas and solid char is determined at 550oC, 600oC, and 450oC respectively, according to the computed pyrolysis kinetic parameter on oil recovery from various waste plastics. The mono-graphic analysis is also used to classify different waste residual char. The model reduces the volume of waste plastic by 89.2%, lowering the detrimental impacts on all living things while simultaneously producing a synthesis of petroleum fuel as a by-product that may be utilized as a replacement or addition to traditional fuel.
Assessing the Capacities of Different Remote Sensors in Estimating Forest Stock Volume Based on High Precision Sample Plot Positioning and Random Forest Method

Forest stock volume (FSV) is an important forest resource indicator. Satellite images from various sensors have been used to estimate FSV. However, there is still a lack of comparative studies on the estimation of FSV with remote sensing data obtained by different sensors. In addition, there is a lack of high-precision ground sample positioning methods, which can improve the matching of ground data and remote sensing data to a certain extent, and improve the estimation accuracy. In this research, a new ground sample plot positioning method was proposed, which could achieve sub-meter positioning accuracy in forest areas, greatly improving the matching accuracy of ground sample plot data and remote sensing data. Based on this high-precision positioning method and the random forest algorithm, we compared and quantified the ability of different sensors to estimate the FSV. The results by random forest modeling showed that the images from a single sensor, Sentinel-2, performed best in the test dataset (R2 = 0.57, RMSE = 70.12 m3 ha-1). For the data from two sensors, the best performance was achieved by the combined Sentinel-2 and PALSAR2/PALSAR data, which had an R2 of 0.62 with RMSE of 65.51 m3 ha-1 in the validation data. The images from the three sensors, Sentinel-2, Landsat-8, and PALSAR2/PALSAR, achieved a modeling accuracy of R2 (0.62) and RMSE (65.40 m3 ha-1). The results clearly showed the capacity of the different sensor data to estimate FSV based on the high precision sample plot positioning method, and it will help forest researchers investigate and estimate the FSV in the future.

The Quaternary period is considered one of the most eventful periods of all geologic periods. The present study intends to understand the paleo-environmental conditions that prevailed in the southern part of the Kerala State, India, during the Late Quaternary period. The present study aims to understand the climatic variability of the Holocene epoch in the Chirakkara region, the easternmost part of Polachira wetland, Kollam district, South Kerala, by using granulometric data and geochemical proxies. A core of 2.5 m in length has been collected from the study area, and both textural and TOC/TN analyses were carried out. The variation in grain size is attributed to the variations in the energy level of the transporting medium and turn to the climatic conditions, especially rainfall. The sediments encountered in the core are dominated by sand-sized particles indicating dynamic high energy conditions and high precipitation events. The ternary plot of the sediment samples also suggests violent environmental conditions during the deposition of the sediments. The predominance of low values of TOC/TN ratio found at both ends of the core indicates an autochthonous source for organic carbon, possibly due to the aggravated aquatic phytoplankton activity, and increased lake bioproduction, and/or decline in the delivery of organic matter from the terrestrial environment. High values of the TOC/TN ratio noted at the middle portion of the core at depths from 120 cm to 210 cm indicate the allochthonous source for the organic carbon. Among allochthonous sources, the C3-type plant is dominant, indicating a cool and wet climate. At the same time, the extremely high TOC/TN values at 170 cm core depth indicate a short period of hot and sunny climatic conditions. The analysis of the granulometric data and organic matter proxies suggest that the study area has experienced wet climatic conditions with occasional dry spells during the Late Quaternary Period.

Renewable energy technologies are developing day by day. One of the novel renewable energy technologies is microbial fuel cells (MFC). MFCs are eco-friendly as it uses electroactive bacteria (exoelectrogens) to generate electricity by using organic and inorganic waste from the wastewater. Electricity generation and wastewater treatment are its primary applications. The construction of MFC consists of the electrodes which may be modified by using nanoparticles (gold and iron oxide) or pre-treatment methods (sonication and autoclave sterilization). This technology is further studied for the detection and reduction of toxic heavy metals in wastewater. The MFCs are also modified into microbial electrolysis cells to make biofuel such as hydrogen. The present review is based on the applications of the MFC, key challenges, and modification strategies.
