Analysis of the Effectiveness of Different Types of Distance Learning

<p style="text-align: justify;">The purpose of this paper is to determine the relevance of turning the camera on or off during distance learning as an argument for active or passive student participation. Seventy-five (75) students participated in the study and were divided into five groups (1-5) according to teaching method (i.e., synchronous instruction online with camera (1) and without camera (2), synchronous transmission of the recording online with camera (3) and without camera (4) and received the online instruction (5)) only. In the beginning and at the end, all students were tested with the same adapted test to determine general physical and motor status. All groups had the same training program twice a week for 45 minutes for 7 weeks. The first training of the week was dedicated to strength development, the second to endurance. In the end, all participants completed a questionnaire to determine their additional physical activity and how they felt about using a camera. The camera being turned on was identified as a factor that made participants uncomfortable but contributed significantly to the effectiveness of the course. However, 94.6 % of all participants cited non-camera methods as their favourite.</p>

Hydroxychloroquine/Chloroquine in COVID-19 With Focus on Hospitalized Patients - A Systematic Review

Background In the beginning of the COVID-19 pandemic, many hospitalized patients received empiric hydroxychloroquine/chloroquine (HC/CQ). Although some retrospective-observational trials suggested potential benefit, all subsequent randomized clinical trials (RCTs) failed to show benefit and use generally ceased. Herein, we summarize key studies that clinicians advising patients on HC/CQ efficacy:safety calculus in hospitalized COVID-19 patients would want to know about in a practical one-stop-shopping source. Methods Pubmed and Google were searched on November 4, 2021. Search words included: COVID-19, hydroxychloroquine, chloroquine, in vitro, animal studies, clinical trials, and meta-analyses. Studies were assessed for import and included if considered impactful for benefit:risk assessment. Results These searches led to inclusion of 12 in vitro and animal reports; 12 retrospective-observational trials, 19 interventional clinical trials (17 RCTs, 1 single-arm, 1 controlled but unblinded), and 51 meta-analyses in hospitalized patients. Inconsistent efficacy was seen in vitro and in animal studies for coronaviruses and nil in SARS-CoV-2 animal models specifically. Most retrospective-observational studies in hospitalized COVID-19 patients found no efficacy; QT prolongation and increased adverse events and mortality were reported in some. All RCTs and almost all meta-analyses provided robust data showing no benefit in overall populations and subgroups, yet concerning safety issues in many. Conclusions HC/CQ have inconsistent anti-coronavirus efficacy in vitro and in animal models, and no convincing efficacy yet substantial safety issues in the overwhelming majority of retrospective-observational trials, RCTs, and meta-analyses in hospitalized COVID-19 patients. HC/CQ should not be prescribed for hospitalized COVID-19 patients outside of clinical trials.

Influence of Optic Cable Construction Parts on Recovery Process after Gamma Irradiation

Fibre optic cables are widely used as communication cables in Instrumentation and Control (I&C) systems. In the case of nuclear power plants (NPPs), using optic cables in mild environments outside of containment areas are very common. However, at present, there is a need for fibre optic cables to be used in containment areas, i.e., with radiation. An optical fibre consists of a highly transparent core that possesses a higher refractive index than the surrounding transparent cladding, which possesses a lower refractive index. Most optical fibres are manufactured from glass (silica with required dopants) which is created at high temperatures from the reaction between gasses. The glass used in optical fibres is sensitive; it becomes dark during exposure to radiation, which compromises the optic functions. That is why there has been a slow infiltration of optic cable in NPP containment areas. Radiation resistant optic fibres have been developed. Although these fibres are called “radiation resistant,” they go through a darkening process (absorbance increase) as well, but not as quickly. Immediately after the irradiation has stopped, a recovery process starts in the glass structure. During this period, optical losses of the glass improve, but not to the original level as before the irradiation. During the testing of optic cables for the installation in nuclear power plant containment areas, we observed an unusual recovery process. In the beginning, a healing effect was observed. However, after a few days of recovery, the healing process stopped, and the trend changed again as a worsening of the optical properties was observed. This paper describes experiments which explain the reasons for such an unexpected behaviour.

This program is designed for the students who study in Islamic Boarding School Daarul Muti’ah, Kampung Ciputat, Tajur, Ciledug in understanding the grammar materials; present forms (present tense, present continuous, present perfect) as a response to learning process during the pandemic COVID-19 because English is one of subjects in the school which needs extra understanding particularly grammar. This program is conducted approximately 1.5 month which started in the beginning of June 2021 until mid of July 2021. The program tries to reveal; 1) the process of learning present forms which is conducted as the response to pandemic COVID-19 for the students who study in Daarul Muti’ah Kampung Ciputat, Tajur, Ciledug and 2) the process of learning present forms can help the students who study in Daarul Muti’ah Kampung Ciputat, Tajur, Ciledug to increase their English language proficiency. The method of the program is offline by giving workshop and giving feedback to the students. Pre-test is conducted before the program by giving the students some questions related to Present forms. Also, the post-test is conducted to know their ability to measure and understand the Present forms concept after having this program.

Appositeness of artificial intelligence in modern medicine

Artificial intelligence (AI) can be demonstrated as intelligence demonstrated by machines.AI research has gone through different phases like simulating the brain, modeling human problem solving, formal logic, large databases of knowledge and imitating animal behavior. In the beginning of 21st century, highly mathematical statistical machine learning has dominated the field, was found useful and considered in helping to solve many challenging problems throughout industry and academia. The domain was discovered and work was done on the assumption that human intelligence can be simulated by machines. These initiate some discussions in raising queries about the mind and the ethics of creating artificial beings with human-like intelligence. Myth, fiction, and philosophy are involved in the creation of this field. The debates and discussion also point to concerns of misuse regarding this technology.

In the beginning was . . . the word. Cycles of Influence: A historical analysis of some seminal influences on the evolutionary development of mediation principles, values and practice models

A historical analysis of seminal influences on the evolutionary development of mediation principles, values and practice models. This article will focus on the ideas of pioneering individuals who had a significant role and influence on contemporary mediation principles and practice. It will describe their professional field of practice; the particular principles and values that underpinned their practice; the theoretical models and styles of practice they developed and how those became transported into contemporary mediation practice. The relevance for mediation is to raise awareness of the centrality, significance, and importance of these key principles. Ideally, this will in turn impact on the quality of contemporary practice. Hopefully it will inform or remind reflective practitioners, trainers, and practice consultants of what constitutes the foundations of best practice.

Influence of tillage methods on the yield of winter rye variety Sudarushka

The results of studying the elements of the technology of cultivation of a new variety of winter rye Sudarushka are presented. The research took place in 2019, 2020 in the sub-taiga zone of the Tomsk region. The impact of soil cultivation methods as well as the impact of humic fertiliser from peat Gumostim on the yield of winter rye Sudarushka is evaluated. The soils of the experimental plot are acidic (pH 4.3) soddy-podzolic loamy sandy loam. The arable horizon has a low humus content (1.5%), a low (0.2 mg/100g) content of nitrate nitrogen, a medium content of mobile phosphorus (19.2) and exchangeable potassium (7.1) and a high (11.0 mg/100g) content of mobile aluminium. The scheme of the experiment included four variants of cultivation: ploughing of fallow lands with PlN-4-35 + cultivation KPN-4,2, sowing without packing and with packing; disking with BDMK-2,8 + cultivation KPN-4,2, sowing without packing and with packing. Treatment with humic fertilizer from peat Gumostim at a concentration of 0.001% was carried out during the growing season in the beginning phase of the leaf-tube formation. The average yield of winter rye in the variety Sudarushka during the years of research was 4.66 t/ha in the variant with disking, subsequent cultivation before sowing and further sowing with packing, which is 0.34 t/ha higher than with the traditional method of soil cultivation. The application of humic fertilizer from peat Gumostim on cold sod-podzolic soils enabled the average yield of winter rye to be 4.31 t/ha y, which is 0.39 t/ha higher than without the fertilizer.

A Case Study of the Effectiveness of Online Graduate Teacher Education in TESOL

A cadre of school teachers took part in three semesters of online coursework to earn TESOL certification. They participated in a hybrid university math course and a face-to-face summer institute on effective teaching of math to English learners. Participants took pre and post-tests aligned to Common Core elementary mathematics content and the Praxis Test for Teachers of English to Speakers of Other Languages. They were observed teaching a math lesson in the beginning of the project to evaluate effectiveness in TESOL instructional strategies. A follow up observation was conducted the following semester. Both observations were scored using the sheltered instruction observation protocol (SIOP Model). Assessment and observation results indicated statistically significant growth in content and pedagogical knowledge and application. A qualitative analysis suggests flexibility in the form of online and hybrid courses, financial support, and practical application of new concepts to current practice are key factors in successful professional development for practicing teachers.
