Standardization of EFL Undergraduate Skill Exam Papers: A Case Study at Majmaah University
Authors: Othman Abahussain Majed , Iqbal Muhammad , Khan Imran
Published: December 2020

Designing standardized exams for EFL undergraduates is a matter of great concern in pedagogical practices that assess learners’ academic achievements. This case study was conducted at Majmaah University, Saudi Arabia, to explore the significance of educational exam standardization and its impact on the process of implementation, leading to a balanced and equitable assessment of English language skills. During the study, 250 final English skill exam questions of two semesters were analyzed. A mixed-method approach using a questionnaire and Focused Group Discussion was adopted to collect relevant data. The quantitative data were analyzed using SPSS 16, and the qualitative data was processed by thematic analysis. The quantitative data results showed that questions were balanced, valid, and reliable in language skill exam papers designed for undergraduate English students. The qualitative data revealed four major themes – standardization of questions, the efficacy of Bloom’s taxonomy, assessment/evaluation, and alignment of the question with learning outcomes. These emerging themes highlighted the effectivness of standardizing exam papers, identified problems, and suggested ways of improvement. The study indicates that exams must be scrutinized for the sake of standardization in terms of maximum course coverage; the variety in the question item; clear, concise, and precise instructions; validity and reliability of exam papers; and the alignment of questions with the course and program learning outcomes to ensure the implementation of the revised Bloom’s taxonomy. The study suggests, to generalize the results, that further investigation should be done in another Saudi university for the sake of comparison.
VIDEOCONFERENCING FOR SPEAKING ASSESSMENT MEDIUM: ALTERNATIVE OR DRAWBACK?
Authors: Nova Muhamad
Published: December 2020

The urgency of technology integration has arisen due to the current pandemic break. With a sudden shift from conventional learning to virtual learning, less proper preparation on utilizing the technology integration may occur. The present study aimed at unraveling the perception and obstacles faced during the implementation of videoconferencing as a speaking assessment medium. By applying qualitative research with a snapshot case study design in a vocational education institution, this study gained the data through questionnaires, focus group discussion, and an interview. As a result, the majority of the students perceived negatively toward the implementation of videoconferencing as a speaking assessment medium. These negative reactions occurred due to the nervousness and anxiety along the online speaking assessment process. Moreover, the obstacles faced, such as bad internet connection, technical problems, and surrounding disturbance, also contributed an impact on studentsâ€™ language production and the sound heard by the students during the online speaking assessment. From the results of the present study, the application of videoconferencing as a medium in assessing studentsâ€™ speaking ability needs to be reappraised to preview its function whether it can be used as an alternative way or it contributes a drawback effect during the assessment process.
Temporary contracts and Okun?s law in Poland
Authors: Bartosik Krzysztof
Published: December 2020

Research background: The share of temporary workers in Poland is one of the largest of any EU country, which may affect the output unemployment relationship. The Polish case seems to be a natural experiment. Contrary to many advanced European countries, the spread of temporary contracts in Poland was not caused by labor market reform but instead resulted mainly from spontaneous processes.
Purpose of the article: This paper investigates the effect of the widespread use of temporary contracts on the relationship between output and unemployment in Poland.
Methods: The analysis is based on the ?dynamic? version of Okun?s law and uses OLS regression, OLS split-sample regression and OLS rolling regression. The sample period is 1996?2018.
Findings & Value added: The study found that unemployment?s sensitivity to output increased over time and was related to the greater use of temporary contracts, particularly among young people and women. Initially, at the turn of the 21st century, the expansion of temporary jobs changed the employment composition and had an insignificant effect on unemployment since firms mainly replaced permanent contracts with temporary contracts. Then, starting around 2006, temporary contracts began affecting unemployment levels and unemployment?s responsiveness to output. During this period, firms used temporary contracts as the main workforce adjustment device during the business cycle.

Published: December 2020

Abstract— In an organizational environment, there are various business process models with the same procedures. If an organization builds a system with the same procedure repeatedly, it will undoubtedly incur a lot of effort and money. Therefore, it is necessary to extract common fragments to save effort. This research uses four scenarios of business process models: sequence, branching, nested branching, and looping. This study uses Business Process Modeling Notation (BPMN) notation so that the process model consists of activities, connectors, and gateways. Structural similarity is measured using the Jaccard similarity formula by comparing the process model. The similarity of behavior is measured using the Transition Adjacency Relations (TARs) method to obtain common fragments. The results show that the sequence process model will produce a common fragment that tends to be sequential too. The branching will produce a common fragment that tends to branch, and nested branching will produce a common fragment that tends to be branched and nested, as well as looping will produce a common fragment contains looping too. The experimental results show that the proposed method can extract common fragments based on the available business process models.

Keywords—BPMN; common fragment; behavioral similarity; TARs

 

Abstrak— Dalam lingkungan organisasi, terdapat berbagai model proses bisnis dengan prosedur yang sama. Jika suatu organisasi membangun sistem dengan prosedur yang sama secara berulang-ulang, niscaya akan mengeluarkan banyak tenaga dan biaya. Oleh karena itu, perlu mengekstrak fragmen umum untuk menghemat tenaga. Penelitian ini menggunakan empat skenario model proses bisnis yaitu sequence, branching, nested branching, dan looping. Penelitian ini menggunakan notasi Business Process Modeling Notation (BPMN) sehingga model proses terdiri dari aktivitas, konektor, dan gateway. Kemiripan struktural diukur menggunakan rumus kemiripan Jaccard dengan membandingkan model proses. Kesamaan perilaku diukur menggunakan metode Transition Adjacency Relations (TARs) untuk mendapatkan fragmen yang sama. Hasil penelitian menunjukkan bahwa model sequence process akan menghasilkan common fragment yang cenderung berurutan juga. Percabangan akan menghasilkan fragmen umum yang cenderung bercabang, dan percabangan bersarang akan menghasilkan fragmen umum yang cenderung bercabang dan bersarang, serta perulangan akan menghasilkan fragmen umum yang berisi perulangan juga. Hasil eksperimen menunjukkan bahwa metode yang diusulkan dapat mengekstrak fragmen umum berdasarkan model proses bisnis yang tersedia.

Authors: Khoi Tran Tien , Chuong Nguyen Dang Hoang , Phuc Hoang Gia , Thuy Nguyen Thi , Huy Nguyen Nhat
Published: December 2020

In this study, we aimed to use ferrate as an all-in-one alternative for the removal of chlorine-consumed compositions such as organic, color, turbidity, iron, and manganese in river water for water supply purposes. Ferrate (FeO42-) was simultaneously employed as coagulant and oxidant for purification of Saigon River water in order to reduce the formation of disinfection by-products in the produced tap water. The Jartest was conducted using both ferrate for raw river water and poly-aluminum chloride (PAC) for chlorinated water to determine the optimum concentration of chemicals and pH values as well as comparing the effectiveness of ferrate and traditional coagulation with pre-chlorination technology for surface water purification. Results showed that ferrate could be used to remove organic compounds with high efficiency of 86.2% at pH 5 - 6 and ferrate concentration of 16 mgFe/L. Moreover, the removal efficiency for turbidity, color, and iron were at least 90%, indicating that ferrate would be a very promising alternative for chlorine and PAC for water purification.

Authors: Thuy Le Phuong , Tu Bui Ngoc , Tuan Pham Le , Binh Tran Quoc
Published: December 2020

Urban transportation infrastructure development projects usually act as a lever for real estate values. This research aims to assess the effects of some projects on urban land prices in three wards of Cau Giay District, namely Quan Hoa, Dich Vong, and Dich Vong Hau wards. With 161 samples surveyed, we established a multivariate linear regression model initially having 11 variables. As the result, six variables are identified as having significant effect on land prices in the study area. Among those, three variables are related to the local transportation infrastructure, namely: location of land parcels; distance to urban railway lines; and distance to public transport stations. Location of land parcels and distance to public transport stations are factors that have a significant influence in reality. Besides, the distance to the urban railway lines is the factor that has a positive impact on land prices, but it is only still a potential and should be extensively investigated in the future because the urban railway project is still in the implementation phase.

Published: December 2020

Studying coastal landscapes is an important and meaningful content in determining the natural and human properties of the territory and territorial sea, which is a valuable scientific basis for spatial planning in the economic development associated with the use of resources and environmental protection. The Quang Ngai’s coastal area is determined according to the continental boundary of 6 maritime districts/ cities and the boundary on the sea of the provincial coastal fishing zone. Coastal landscapes include terrestrial landscapes, marine landscapes, and island landscapes formed by the result of the interaction of natural components and human factors. The landscape structure of the coastal areas in Quang Ngai includes 1 system, 2 sub-systems, 3 classes, 6 sub-classes, 10 types, and 108 kinds of landscapes, In which, there are 75 kinds of terrestrial landscape, 27 kinds of marine landscape, and 6 kinds of the island landscape. The landscapes of the study area have differentiation from west to east (from the low mountain landscapes, hill - plain landscapes to marine landscapes and island landscapes) and from north to south, which is clearly represented in the differentiation of plain landscape kinds. The landscapes are highly variable, sensitive to external impacts, including development activities.

Authors: Kwang En Tan
Published: December 2020

The most fascinating thing in stock market world is forecasting stock prices. Almost all players in stock market race to find the best method for forecast stock prices. After years of researching and practicing, we can divide all methods into two main methods, fundamental and technical analysis. Fundamental analysis based its forecasting method on macroeconomic factor, industry analysis, and company internal factors, while technical analysis based on studying financial accounting numbers and stock price trends in the past and present. This study will be focusing in the uses of technical analysing in forecasting stock prices.There are many ways in technical analysis to forecast stock prices. Investors and analysts usually use stock price trends or financial ratios to do that. The latest is the most simple and powerful tools that almost everyone can use it, regardless to its limitations. When it comes to use financial ratios, there are a lot of contradicting results that make its users need to make a comparation between ratios and make a decision. This paper try to use another solution to overcome those problem with using a composite indicators. The composite indicator will be compared with another market ratio to find out which method is the best on forecasting stock prices.The result is composite indicator is the best method on forecasting stock prices compared with price to sales ratio, price to book value ratio, price to earnings per share ratio, and price to operating cash flow ratio.
THE INFLUENCE OF ENVIRONMENTAL PERFORMANCE, ORGANIZATIONAL REPUTATION, ENVIRONMENTAL DISCLOSURE AND ENVIRONMENTAL STRATEGY ON BUSSINESS PERFORMANCE
Authors: Saputra Indra
Published: December 2020

This research aims to examine and analyze the influence of environmental performance, organizational reputation, environmental disclosure and environmental strategy on bussiness performance. In this research, the target population of this study was the manufacturing companies registered and participating in the Company Performance Rating Program (PROPER) issued by the Ministry of Environment in 2011-2016 with the sampling method using purposive sampling criteria, totaling 22 companies with 132 observations. Data analysis consists of descriptive and multiple regression linear regression. The results showed that the company’s reputation had a significant influence and environmental disclosure had a significant positive influence on business performance, while environmental performance and environmental strategy had no significant influence on business performance. Based on the evaluation, the environmental strategy will lead to company policies towards the application of an environmental management system. The current condition occurs that environmental strategy cannot make investors make decisions to buy shares because many other fundamental factors are the main consideration for investors in buying shares, meanwhile multitude of other factors and the main focus of the company as a business strategy is the fundamental reason that environmental strategy does not affect stock prices. This research is also expected to contribute conceptually to the company in determining further policies regarding the performance of a company to be more influenceive in its implementation.

Authors: Pérez-Moreno Diana P Pérez-Moreno , Plancarte-Sánchez Ricardo , Hernández-Porras Carolina , Guillén-Núñez María del Rocío
Published: December 2020

Introduction: Severe oncological pain occurs in up to 60% of pelvic abdominal cáncer patients, being refractory to medical management in up to 30% of cases. In 1990, the superior hypogastric plexus neurolytic block (SHPB) was described for the control of pain in these patients. This study aimed to evaluate the effectiveness of this technique for the control of oncological pain. Methodology: Studies that evaluated the effectiveness of the SHPB using the classic or transdiscal approach in adult patients with oncological abdominal-pelvic pain were systematically reviewed. A search was conducted in PubMed, EMBASE and Scopus from January 1, 1990, to August 31, 2019, without a language restriction. The visual analog scale (VAS), morphine milligram equivalents (MME) per day, quality of life and presence of complications were recorded. The quality of the studies was evaluated using the Jadad and Ottawa-Newcastle scales. Results: Eight studies met the inclusión criteria: 6 were descriptivo longitudinal studies, and 2 were controlled clinical trials, comprising 316 patients (75% female and 25% male; average age 53.2 years); the most frequent diagnoses were gynecological (65%) cancer. An average VAS reduction of 55%-60.8% was obtained as well as a MME reduction of 40%-60%. Three studies evaluated the quality of life using the (QLQ-C30), (PSS) and Zubrod scale all with positive results. Complications were reported in 18% of cases, pain related to the puncture was the most frequent. Conclusions: The SHPB may be an effective for the control of severe oncological abdominal-pelvic pain, decreasing the VAS and MME and improving the quality of life of patients.
Anestesia cardiovascular en cirugía no cardiaca
Authors: Borchert Evelyn , González Katia , Lema Guillermo
Published: December 2020

La valoración clínica sigue siendo uno de los pilares fundamentales en la evaluación del riesgo anestésico-quirúrgico. Los scores de riesgo para la evaluación cardiovascular y cirugía no cardíaca se basan tradicionalmente en la exclusión de condiciones cardíacas activas, la determinación del riesgo de cirugía, la capacidad funcional del paciente y la presencia de factores de riesgo cardíaco. En las últimas décadas, nuevas guías incorporan una asociación entre los biomarcadores cardiacos y los eventos cardiacos adversos. Para el manejo de pacientes coronarios en tratamiento antiagregante doble, derivados a cirugía no cardiaca, hay que considerar el riesgo de trombosis del stent, las consecuencias de retrasar el procedimiento quirúrgico y el aumento del riesgo de hemorragia. Hasta la fecha no existe evidencia acerca de cuál es el mejor manejo anestésico que disminuya las complicaciones cardiovasculares perioperatorias en este grupo de pacientes. Este artículo, hace referencia a las diferencias de la valoración preoperatoria para cirugía no cardiaca incorporados en las guías del American College of Cardiology, la American Heart Association, la European Society of Cardiology y la Canadian Cardiovascular Society. Algunas consideraciones acerca del manejo de pacientes coronarios, terapia antiplaquetaria dual y eventuales complicaciones. Se incluyen algunas estrategias farmacológicas, así como consideraciones específicas para el perioperatorio, con el fin de reducir morbilidad de origen cardiovascular.

Authors: Arturo Lorenzo B. Arturo , Jiménez Oscarin
Published: December 2020

Los trastornos de la coagulación han sido uno de los problemas con que los clínicos han lidiado en el transcurso del conocimiento de esta nueva patología. Existe muy escasa evidencia y limitadas recomendaciones por parte de las Sociedades Científicas sobre el manejo de la tromboprofilaxis en el paciente quirúrgico COVID-19, aunado a que se desconoce los efectos de esta patología sobre la injuria quirúrgica. La evaluación del riesgo trombótico en cuanto al paciente quirúrgico COVID-19 no cuenta con precedentes al respecto. Algunos predictores y factores de riesgo de trombosis se han informado sistemáticamente como marcadores pronóstico, entre ellos la elevación del dímero-D, fibrinógeno, IL6, ferritina sérica, prolongación de tiempos de coagulación, detección anticuerpos antifosfolípidos y otros factores independientes que contribuyen a medir la gravedad de COVID-19 como lo es la lactato deshidrogenasa y la linfopenia marcada. Los anteriores predictores y factores de riesgo de trombosis para la enfermedad de COVID-19 se han adaptado ajustados a las categorías presentes en la escala de Caprini en orden creciente de complejidad y en relación a la morbimortalidad. En este sentido la elección de la o las medidas que requiere cada paciente dependerá de su riesgo particular de desarrollar enfermedad tromboembólica venosa contra el riesgo anticipado de complicaciones hemorrágicas quirúrgicas de la cirugía a la que será sometido, permitiendo identificar a los pacientes susceptibles de desarrollar complicaciones a través del sistema de puntuación modificado de Caprini y a la vez guiar y establecer estrategias óptimas de tromboprofilaxis.

Published: December 2020

Introducción: La amigdalectomía con o sin adenoidectomía, es una de las cirugías más frecuente en población pediátrica. Desde hace varios años se ha vuelto una intervención predominantemente ambulatoria, por lo que lograr identificar los factores que influyen en el sangrado intraoperatorio es de suma importancia para prevenir complicaciones postoperatorias y reshospitalización. Material y Método: Se realizó un estudio observacional de corte-transversal. Se incluyó a pacientes entre 1 y 14 años sometidos a amigdalectomía con o sin adenoidectomía entre noviembre de 2015 y mayo de 2017, obteniendo un total de 709 casos evaluados. Se determinó el sangrado intraoperatorio de forma volumétrica. Posteriormente, se realizó un análisis multivariado con un modelo de regresión lineal generalizado. Resultados: Se cuantificó el sangrado intraoperatorio promedio en 1,9 ml/kg (IC 95%; 1,7-2,05). El uso de propofol (aumento del 30% del sangrado) y tiempo quirúrgico (2% por cada incremento de un minuto) fueron factores de riesgo. Mientras que el uso de electro bisturí se asoció con una disminución del 50% en relación al no uso (p = 0,001). Conclusiones: Fueron factores de riesgo para sangrado intraoperatorio el uso de propofol y un tiempo quirúrgico prolongado. El uso de electrobisturí constituyó un factor protector.

Authors: Sultan Sherif S , Ahmed Fahmy Nouran Mohsen , Hassan Mohamed Ibrahim , Emam Dalia Fahmy
Published: December 2020

background: Postoperative sore throat (POST) is defined as pain or discomfort in the throat following general anesthesia. Throat packs are used by many surgical subspecialties for different benifits, however they may increase the incidence of POST. Many interventions can be used to decrease incidence of POST. Triamcinolone acetonide (TA) is a moderately potent topical corticosteroid preparation. In this study, we hypothesized that soaking the throat pack with TA may decrease POST. Methods and Material: This prospective interventional comparative study was performed on 54 patients planned for Functional Endoscopic Sinus Surgeries (FEES) surgery. After endotracheal intubation, a standard length of oro-pharyngeal pack was placed, then patients were randomly allocated into: Group I: Oro-pharyngeal packs were soaked with 15 mg Triamcinolone acetonide 0.1% and Group II: packs were soaked with the same volume of lubricating gel (K-Y gel®). The patients were postoperatively asked about: sore throat, dysphagia, hoarseness of voice and nausea and vomiting. Results: Thirty minutes and 24 hours after extubation, Group I patients showed lower but statistically insignificant sore throat scores. Two to six hours after extubation, Group I showed a statistically significant reduction in sore throat scores. Six patients suffered dysphagia in group I compared with 8 patients in group II. Hoarseness of voice occurred in 1 patient in group I and 3 patients in group II. No patient complained of nausea or vomiting. Conclusión: Soaking oropharyngeal pack with triamcinolone acetonide in orabase gel was able to decrease POST in FESS patients.

Authors: Ghiringhelli M. Juan Pablo , Fuentes Rodrigo , O’Reilly F. Paula
Published: December 2020

La anestesia libre de opioides (OFA) es una técnica anestésica donde no hay administración de opioides, tanto en el intraoperatorio como en el postoperatorio. Aunque una de las bases de la analgesia intraoperatoria podrían ser los opioides, los desafíos actuales están enfocados en reducir su uso perioperatorio, previniendo sus efectos adversos, racionalizando y limitando su empleo específicamente en poblaciones de riesgo como síndrome de apnea obstructiva del sueño (SAHOS), obesidad, enfermedad pulmonar obstructiva crónica (EPOC) y cirugía oncológica. Presentamos este caso de OFA en un paciente susceptible de complicaciones por uso de opioides sometido a una hemicolectomía derecha extendida. Se realizó analgesia multimodal con peridural torácica y dosis subanestésicas de agentes endovenosos como dexmedetomidina, ketamina y propofol, acompañado de anestésicos locales periglóticos de corta y larga duración. Se otorgó una adecuada analgesia intra y postoperatoria, el paciente no tuvo eventos adversos, presentando una buena recuperación, deambulación y extubación precoz.

Authors: De Souza Cinoélia Leal , Duarte Ana Cristina Santos , Da Silva Elaine Santos , Magalhães Denise Lima
Published: December 2020

Objetivo: Analisar as ações de promoção da saúde na Estratégia Saúde da Família. Métodos: Pesquisa quantitativa descritiva, realizada com 331 usuários de 11 Unidades de Saúde da Família em um município da Bahia em 2018. Para a coleta de dados utilizou-se um questionário semiestruturado composto por questões relacionadas aos aspectos socioeconômicos, socioambientais e de saúde. Resultados: O usuário da Estratégia Saúde da Família pouco percebe a proximidade dos profissionais no seu dia a dia, além de pouca resolutividade do serviço, principalmente nas ações de promoção da saúde no território, visto a baixa evidência de atividades de educação em saúde que abordem temas importantes para a promoção da saúde ambiental e superação dos desafios socioambientais no território, como as próprias doenças infecciosas associadas ao ambiente. Foi constatado que o trabalho ainda é focado em métodos assistenciais curativos, caracterizado por ações num território essencialmente definido por limites geográficos. Conclusão: É essencial que o ambiente comunitário seja incorporado às práticas dos profissionais, para que o território seja uma ferramenta aliada à produção de saúde e não reprodutor da assistência voltada apenas para aspectos biológicos e patológicos.

Published: December 2020

Objetivo: Relatar a assistência multiprofissional aos pacientes em tratamento de COVID-19 com vistas à minimização do distanciamento familiar em um serviço de pronto atendimento em Manaus. Relato de Experiência: Quando foi declarada a transmissão comunitária no estado do Amazonas, em abril de 2020, todas as unidades da rede de alta complexidade estadual foram designadas para a pandemia passaram a receber pacientes com o diagnóstico, o que gerou lotação de leitos, atrasos de transferências e sobrecarregou todas as unidades de urgência e emergência. O Serviço de Pronto Atendimento estava tratando os pacientes suspeitos e confirmados para Covid-19 com os suprimentos e recursos humanos que possuía. A situação trazida pela Covid-19 fez repensar práticas profissionais, de forma que se realizasse um cuidado mais humanizado aos usuários e familiares. O acolhimento da família, vídeo-chamadas entre pacientes e famílias mediadas pela equipe multiprofissional e outras medidas foram estabelecidas para fortalecer o enfrentamento à doença.  Considerações Finais: As medidas realizadas foram de grande importância para atenuar os impactos do distanciamento familiar dos pacientes e enfrentamento à doença, assim como o conforto aos familiares que podiam visualizar, mesmo que virtualmente, o cuidado que estava sendo oferecido.

Percebeu-se uma evolução significativa após a primeira reunião, que por meio de educação em serviço, os registros de enfermagem se tornaram mais consistentes, tendo impacto direto na assistência prestada ao paciente e também ao serviço de auditoria em saúde. Considerações Finais: Através da vivência foi possível identificar uma forte influência dos registros de enfermagem no processo de auditoria em saúde, além da expressiva correlação com a melhoria da assistência prestada pelos profissionais de enfermagem. Por fim, o estudo apresenta limitações, uma vez que não houve possibilidade de presenciar as reuniões posteriores, a fim de que fosse possível realizar um comparativo mais abrangente envolvendo vários meses consecutivos.

Richard Hughes’s homoeopathic philosophy: A short review
Authors: Sonny Ranjit
Published: December 2020

Background:

After Dr. Christian Friedrich Samuel Hahnemann, several stalwarts appeared on the horizon of Homoeopathy, one of these was Dr. Richard Hughes who practiced in the 19th century and stood out because of his philosophical approach. He was a staunch supporter as well as a critic of Hahnemann. He incorporated the latest scientific developments of the time in his practice, making his philosophy unique and progressive. We believe his philosophy will inspire the present generation of homoeopaths to explore homoeopath in the light of cutting-edge scientific inventions.

Methods:

A search of literature, including writings, lectures, and articles written by Dr. Hughes, was done Web pages, Google Search, etc., were explored related to him between April 2020 and July 2020 based on the search results an idea about Hughes’s homoeopathic concept and philosophy was constructed which has been highlighted below.

Results:

Dr. Hughes strongly endorsed Hahnemann’s Similia principle, but rarely used other theories such as Theory of Miasm, Theory of Vital force, and Doctrine of drug dynamization. According to him, similarity should be established between the drug pathogenesy and disease pathogenesis. He advocated low potency prescription, pragmatic, antimystical Homoeopathy and followed the 4th edition of Organon of Medicine. More stress on pathology, opposition to clinical symptoms, and drug proving on animals were the main features of his philosophy. He aimed for the middle path between Homoeopathy and orthodox. He was respected in the homoeopathic and allopathic fraternities and was known as the 3Xer or Half Homoeopath.

Conclusion:

The understanding and teachings of Dr Hughes regarding Homoeopathy are pragmatic, transparent, and simple. He endorsed and practiced only symptom similarity between patient and medicine. He criticized the baseless explanations of homoeopathic theories and interpreted phenomena in the light of scientific development and inventions.
Using of brown algae Sargassum pallidum as raw materials for extraction of fucoxanthin

Fucoxanthin is a widespread carotenoid contained in tissues of brown algae, known by its antitumor activity and ability to suppress cancer cells growth. Its inclusion into diet prevents accumulation of the body fat and regulates level of glucose and insulin in the blood. Fucoxanthin can be considered as a promising nutritional supplement for suppressing obesity. Extraction of fucoxanthin from brown algae Sargassum pallidum is investigated under various conditions. The samples of algae were collected in different sites at Primorye coast in 2018–2019. Two types of the preparations were used ― frozen and dried. The frozen preparations were stored under temperature of –18 оC no more than 30 days. For the dried preparations, fresh algae were dried in a dark room by air fan under temperature of +18–+20 оC and then crushed to powder and stored in dark place under the same temperature no more than 6 months. Content of dry substance in the preparations was 16.4 ± 1.0 % for frozen algae and 93.6 ± 1.0 % for dried algae. Fucoxanthin was extracted from these preparations by method of alcohol extraction using the ethanol water solution in ratio of 1 : 10 during 24 hours in a dark place, then the solution was filtered or centrifuged. Concentration of fucoxanthin in the filtered solution was measured in spectrophotometer relative to a standard solution (ethanol 96 %) with wavelength of 350–800 nm. Yield of fucoxanthin was higher from the frozen preparations, but more ethanol was consumed for its extraction in comparison with extraction from the dried preparations. Besides, the dried preparations were processed during 1 day with the ethanol solution in concentration 96, 88, 84, 80, and 76 %, under various temperature. Yield of fucoxanthin decreased with temperature increasing: the optimal temperature was +7 оC, so the room temperature could not be recommended for extraction. The optimum concentration of ethanol for fucoxanthin extraction was 80 ± 2%.

The discovery of conductive and magnetic two-dimensional (2D) materials is critical for the development of next generation spintronics devices. Coordination chemistry in particular represents a highly versatile, though underutilized, route toward the synthesis of such materials with designer lattices. Here, we report the synthesis of a conductive, layered 2D metal–organic kagome lattice, Mn3(C6S6), using mild solution-phase chemistry. Strong geometric spin frustration in this system mediates spin freezing at low temperatures, which results in glassy magnetic behavior consistent with a geometrically frustrated (topological) spin glass. Notably, the material exhibits a large exchange bias of 1625 Oe, providing the first example of exchange bias in a coordination solid or a topological spin glass. More generally, these results demonstrate the potential utility of geometrically frustrated lattices in the design of new nanoscale spintronic materials.

Coronavirus disease 2019 had caused a pandemic leading to over 6M positive cases worldwide out of which 3.73 lac are demised (until when the article was written). Its first outbreak was seen in Wuhan, China. In the Indian scenario, we have a total of 2 lac cases out of which 5,679 have been deceased (until when the article was written). Due to the high transmissibility of this disease, the entire country is under lockdown to prevent the spread of the virus. The main etiology of this virus is the severe acute respiratory syndrome coronavirus-2(SARS-CoV-2). This affects the respiratory system leading to cough, shortness of breath, and fever. There have been cases with mild or no symptoms reported, but the cause of death is due to the virus. This helps us understand the diagnosis, epidemiology, symptoms, and pathophysiology about the virus, which can help in treatment modalities. An autopsy is one of the methods by which we can understand the systematic involvement other than the respiratory system. Various pathological, microbiological changes can occur in the other organs. Even though the person is deceased, the virus is highly infectious can cause the spread through body fluids. Proper care must be taken while handling the body and performing the procedure. This review article aims to focus on the autopsy findings found in various cases to study the disease pathophysiology of the SARS-CoV-2. This article also helps us understand the guidelines that have been put forward by WHO and CDC must be followed regarding the specification required in the autopsy room; PPE’s to be worn, human waste and fluid disposal, body transportation. Proper personal hygiene must be maintained while handling the COVID-19 patients; this can lead to less susceptibility of acquiring the disease.
