Teaching technical writing to engineering researchers particularly post graduate students is a demanding and complex task. Often the challenge faced by the language instructor is in having inadequate understanding on students' expected writing output which is engineering research publication. While the language instructors may find the language use aspect manageable, it is the understanding on expected writing output for engineering discipline that is a challenge; therefore, supporting language module developers to understand those expected outputs is essential and needed for the advancement in language teaching. In view on the need for the description of the targeted output which is engineering publication, this study focuses on supporting the understanding of engineering research publication specifically on drones. This study is aimed to describe the perimeter of research publication on drones written by prolific engineering writers. This paper uses bibliometric analysis method which is based on identifying the core research and authors, as well as the works that cited them. This study examines 275 research publications indexed in SCOPUS database and also investigates 1947 research publications that cited the 275 publications as reference source. The findings show that the publications are mostly articles, conference papers and reviews deriving mostly from the US, China and the UK whereas the citing documents are mostly from China, the UK and the US. This paper presents the description on the perimeter for both groups. Such description provides a ready narrative to language instructors as well as ready narratives and guidance on writing/content dimension for young scholars embarking on writing scholarly articles on drone research.

Health and medicine has gained a lot of importance in today's digital world, where evolving technology is being used to fight against almost all the known diseases thoroughly. But, according to reports, more than two lakh people in China and one lakh in United States of America are dead every year due to the mistakes made while prescribing errors. This paper aims to propose a system which takes as input the symptoms from the patient to predict the disease, which is followed by recommending the correct medicine. This system consists of database system module where disease dataset contains attributes like "DiseaseID", "Disease", "Symptoms" and "count of occurrences" and drug dataset has additional attributes such as "drug" and "drug_rating". In the data preparation module, a new data frame is created where each disease with its associated symptom is given "1" and "0" if it is not the symptom related. After all these steps of preprocessing are performed on the raw dataset, the dataset is now ready to be acted upon by a machine learning algorithm. Models like Decision Tree, Random Forest and Naive Bayes were applied on the training-dataset. Entire knowledge database was fitted in models and it was seen if not much dataset is used Random Forest And Naïve Bayes classifiers showed 84% accuracy whereas Decision Tree gives 92%. But Random Forest also gives accuracy similar to Decision Tree for large dataset. Hence for disease prediction we use Decision Tree. The recommendation is done on the basis of the rating of the drug. After this, only the drug with the highest rating is included in a newly formed dataset and the rest of the drugs are ignored. The system is implemented for user access by making use of Tkinter a python GUI Library for constructing the desktop end user interface. This paper deals with the design and implementation of a system which performs the function of prediction of diseases and the recommendation of medicines, which adds to the capabilities of the present systems in health infrastructure.

The United States and China are strong trading partners of Malaysia, with about 23% of total exports in 2017. Therefore, the trade war pressures since 2018 between the United States and China have affected the Malaysian economy. Thus, this paper aims to analyse the effects of the war on the Malaysian stock market using a threshold network approach. Then, the networks examine the changes of important stocks before, during and after the trade war in which the periods are taken from 16th March 2017 until 31st May 2021. The important stocks are determined by four standard centrality approaches, namely degree centrality, closeness centrality, betweenness centrality, and eigenvector centrality. This paper uses 240 companies of the FTSE Bursa Malaysia Emas Index to create the Malaysian stock market networks. The results show that Dagang Nexchange Berhad and Jaya Tiasa Holdings Berhad have higher connectivity with other stocks during the turmoil period and after the turmoil period respectively. Besides, Dagang Nexchange Berhad acts as the most important stock according to all centrality measures. The findings of this study give an insight to the government regulators and investors with information regarding the current topological structure of Malaysia's stock market. [ABSTRACT FROM AUTHOR]

Globally, pesticide use continues to rise, estimated to be over four million tonnes yearly. In 2020, it was almost 2.7 million metric tons, up 57% from 1990. Nanotechnology is an innovative and exciting technology that offers new nanoscale molecule designs, formulations, and delivery systems to diminish the hazardous pesticide effects. Many studies on nano-pesticide production have been published, whereas nano-biopesticides are still limited. The purpose of this research is to answer the question of whether nano-biopesticide formulations will emerge along the development of nano-pesticides. The research was conducted by using bibliometric analysis. All nano-pesticide and nano-biopesticide-related publications are extracted from the Scopus with no limitations year. Using VOSviewer, data on research scope, authorship contributions, number of citations, and global research trends are evaluated and mapped. The results show that the publishing of nanoparticles has an exponential trend, with 125 nano-pesticide documents. However, only 14 nano-biopesticide documents are available. India is the most productive country, publishing both nano-pesticides and biopesticides articles, 52 and 9 publications. India connects the Australian and European continents regarding nano-pesticide publications. China is next, with 36 articles about nano-pesticides currently published. Al-Whaibi (average of 86 citations) and Iavicoli have extremely high citation counts (average of 125.5 citations). In synthesizing nano-biopesticide formulations, we found that essential oils are the most common ingredient in nano-biopesticides. In future, the topic related to the impact of nano-biopesticides on crop production and resistance; the combination of nano-biopesticides and nano-fertilizers; the study of nano-biopesticides' effects on the environment; and microbial as nano-biopesticides are some trend in the nano-biopesticide formulation. We predict that research on nano-biopesticides will increase rapidly in the context of eco-friendly issues. Finally, this paper can serve as a basis for the upcoming research on nano-biopesticide formulations, particularly those involving microorganisms as bioactive substances. [ABSTRACT FROM AUTHOR]

This paper studies the impact of a covid-19 pandemic on the global economy. The empirical analysis of the work is based on data before and after (2019-2021) covid-19 and uses OECD data figures. The paper uses comparative analysis to find out changes during the pandemic and at the height of the pandemic, the global economy has passed the lowest point of the crisis, and it began economic growth in the leading countries of the world. This growth, like the crisis, developed in different ways in the economies of the US, EU and China. Our results show that during the pandemic, as a result of the lockdown, almost simultaneously, there was an abrupt increase in unemployment and a decline in production in all countries. In OECD countries, unemployment jumped from 5.2% in February to 8.5% in April, in the US - from 3.5% in February to 14.4% in April, in China - from 5.3% in January up to 6.2% in February. In China, both the epidemic and the economic crisis began earlier than in all other countries, respectively, the economy began to grow earlier. Our findings come to conclusion in a such way, despite the fact that, according to the forecast, the damage in the medium term will be less than after the global financial crisis, it is still significant. So, in 2024, the expected level of world production will be about 3 percent lower than before the pandemic. Countries differ in the degree of expected scarring, depending on the structure of the economy and the scale of the policy response. Emerging market and developing economies are predicted to face more palpable scars than advanced economies. [ABSTRACT FROM AUTHOR]

Preventive conservation, which originated from the field of heritage conservation in Europe, is a concept developed from modern conservation theories and practices. In the field of architectural heritage conservation, it aims to ensure that the value and historical information of architectural heritage are authentically and completely preserved to the maximum extent through minimal intervention. After being introduced into Chinese academia in the early 21st century, preventive conservation as a professional theory has gradually become a research hotspot with extensive discussions. Although preventive conservation is a foreign concept, throughout Chinese architectural heritage conservation history, a fact can be discovered: some practices in China from ancient times to the present have reflected the concept of preventive conservation. In ancient China, cyclical maintenance and regular repairs were important traditions of architectural conservation. The Qing court established the annual repair system, and there were also craftsmen engaged in building maintenance in the folk. In modern times, in response to the needs of protection and management, some protected cultural heritage entities in China carried out various forms of work such as monitoring and periodic inspection to conduct practical explorations of preventive conservation. Moreover, drawing on the international experience of preventive conservation, professionals preliminarily discussed the related issues of architectural heritage conservation in China. Based on years of research and efforts, the concept of heritage conservation in China is changing from "rescue conservation mainly" to "emphasis on both rescue conservation and preventive conservation". This paper gives an overview of preventive conservation of architectural heritage in China, including historical context, theoretical research, policies, and regulations. Furthermore, this paper analyzes the current status of architectural heritage conservation in China in combination with practical projects and conducts in-depth discussions of the existing problems, in order to explore effective methods for preventive conservation of architectural heritage in China.

The concept of ritual originates from religion and has become a core concept of symbolic consumer behaviors. Symbolic value, as part of product value, may also play a role in promoting consumer loyalty. More importantly, this approach can be implemented by relying on a consumption ritualization process. Following the ritualistic path to discuss the realization of platform loyalty is even more urgent in the digital age. This may be attributed to the gamification trend and social features of digital platforms. In this paper, we focus on the symbolic value of digital product as an antecedent to the consumption ritualization process, which is expected to have a positive relationship with platform loyalty. This study has two purposes: (1) review the literature on symbolic value and consumption ritualization, and (2) propose a plausible conceptual model to illustrate the relationship between symbolic value, consumption ritualization, and platform loyalty in the context of digital platforms in China, as moderated by the platform's gamified feature and social feature. More detailed empirical research will be based on structural equation modeling approaches. The research findings will be particularly important for digital platform marketers to timely respond to external events and actively participate in the consumption ritualization practices.

In 2019, the world witnessed a rapid spread of the Coronavirus (COVID-19) disease in one of China's cities, Wuhan. The disease was announced in December 2019 to be a springboard for the whole world, where most countries were infected with it. It greatly affected the health of society and became a real danger to humans. Therefore, it is necessary to diagnose the infected people and quarantine them to combat this pandemic and limit its spread. This paper aims to give a review of COVID-19 diagnosis methods. According to the diagnostic methods, the previous works are classified into two categories for diagnosing Coronavirus; X-ray and Computed Tomography (CT)-Scan. Artificial intelligence (AI) is used to improve the diagnosis accuracy of the presented methods. On this basis, automated diagnostic tools have been developed that distinguish people infected with the Coronavirus from other diseases. Moreover, the performance parameters of the previous studies were compared in terms of diagnosis method, adopted algorithm, diagnosis accuracy, sensitivity, and specificity. Furthermore, the challenges and limitations of the existing methods for diagnosing Coronavirus were explored. AI has proven to be a reliable way to diagnose the spread of the epidemic through advanced algorithms based on blind and machine learning, especially the convolutional neural network (CNN), which plays a vital role in extracting sensitivity, specificity, and accuracy.

A successful vaccination program depends on secure vaccine storage as well as safe and effective vaccine delivery. An Internet of Things (IoT) based vaccine distribution and monitoring model, which is used to transport and monitor vaccines to locations where they will be properly kept for eventual use, is developed and tested. Coronavirus (COVID-19) was first identified in December 2019 in Wuhan city of China, but it is still spreading throughout the world. The impact of this virus is minimized by educating people about its causes and how it spreads is the best way to avoid and slow down transmission. Different technologies have already been developed to minimize the impact of COVID-19, and the Internet of Things (IoT) is one of them. It is a very popular technology that is being used to fight this virus. The vaccination process is already running across the world; maintaining the temperature of the vaccine during the supply chain logistics is the most important task to maintain the effectiveness of the vaccine. In this paper, an IoT-based architecture has been proposed for the effective monitoring and distribution of the vaccine. The developed model can also be utilized for the effective distribution of various types of vaccines and to minimize the wastage of vaccines. [ABSTRACT FROM AUTHOR]

This paper adopts a very convenient 3D CAD method to quickly assess the seismic vulnerability of existing masonry towers. The study selected five typical collapse mechanisms, vertical splitting, base rocking, overturning with diagonal cracks (according to Heyman's approach on tilting towers), a combination of splitting and diagonal overturning and base sliding. The Zhongjiang South pagoda in China is selected as the research case. Basing on the principle of virtu-al works, assuming that masonry behaves as a small cohesion and frictional material, the collapse acceleration is calculat-ed with a direct manual procedure. The research results show that vertical splitting is the easiest collapse mechanism to appear, which is in full compliance with the results of the on-site survey carried out after the Zhongjiang earthquake, fur-ther demonstrating the reliability of this method. Such approach does not require complex mathematical foundations, can be easily mastered by non-professionals, and at the same time greatly reduces the amount of simulations/calculations, a feature which is helpful for the promotion of seismic research of masonry structures.

Today, the whole world is fighting the war against Coronavirus. The spread of the virus has been observed in almost all the parts of the world. Covid-19 also known as SARS-Cov-2 was initially observed in China which rapidly multiplied all over the world. The disease is said to spread by cough, normal cold, sneezing or when a person is in close contact with someone who is already infected. Therefore, the spread of the virus can occur when there is direct contact with an infected person or with the objects touched by the infected person. Hence, it is important to detect the contiguous spread of the virus and control it by taking appropriate measures. Several deep learning models have been used in detecting many diseases like Malaria disease, Lung infection, Parkinson's disease etc. Likewise, CNN model along with other transfer techniques is best proven to detect whether a person is infected with covid positive or not. The dataset consists of 1000 images of covid positive and normal x-rays. The proposed model has been trained and tested on the image dataset with the help of transfer learning models in order to improve the performance of the model. The models VGG-16, ResNet-50, Inception v3 and Xception have achieved an overall accuracy of 93%,82%,96% and 92% respectively. The performance of all the 4 architectures are analyzed, understood and hence presented in this paper. It is hence important to classify and detect covid positive infection and contribute towards making the world Covid-free. [ABSTRACT FROM AUTHOR]

The major problem, nowadays is the novel coronavirus or covid-19 pandemic which has and still infecting people and causing the death of many around the world. Although strict and severe actions have been taken by the government of all over the world to control and minimize the spread of this virus by lockdown, suspending, all travel and sport activity, economic and social activity, quarantines, travel restriction at stations and airport, etc, many of the people around the world have lost their lives and many are suffering. Recently, a conducted study has reported that in China the number of cases that were not documented is 79% as they show no symptom of the virus. In many other countries, the real representation of the patient infected by the virus was different from the real number which was higher in number. Hence, patients with asymptomatic conditions are the major reason for the fast and large covid-19 spread and are also the major reason that caused the people too afraid of the situation. To contribute this global pandemic, in this paper, we propose an investigation which is IoT based system designed to detect both symptomatic-asymptomatic infected people, undocumented, and the place of the pandemic. The aim is to make the authority and people aware of the situation by providing the total numbers of the cases registered, totally recovered, and death of the people caused by the pandemic. In the proposed system, we have used the IoT (internet of things) technology with the NODEMCU-ESP8266, LCD, and Wi- Fi connection to provide information of the important numbers of the patients of covid: cases, recovery, and death of the people in India. This system may keep people more informative, protected, and aware of the danger of the virus so they can take care of themselves and their families in every possible way. [ABSTRACT FROM AUTHOR]
