Published: December 2020

Objectives:

COVID-19 is highly contagious, and health care workers are at high risk of being infected. We carried out a rapid survey to estimate the proportion of HCWs who are serologically positive for SARS-CoV-2 in the Lokmanya Tilak Municipal General Hospital, Mumbai, India.

Material and Methods:

After the consent of the hospital authorities, volunteers were asked to report at a special booth set up in the hospital between May 1, 2020, and May 16, 2020. After consent, each worker was administered a questionnaire using a handheld computer which had questions on symptoms in the past 30 days, place of posting (COVID designated area or other), work category (doctor/nurse/others), use of personal protective equipment, smoking, comorbidity, and exposure followed by a test for COVID-19 using the STANDARD Q COVID-19 IgM/ IgG Duo Test of SD Biosensor. We estimated weighted seroprevalence with 95% confidence limits after adjusting for the work category. We calculated the adjusted odds ratio (aOR) using logistic regression with seropositivity as an outcome variable and others as independent variables.

Results:

The final sample included 501 and 1051 subjects working in the COVID area and non-COVID area, respectively, covering 35% of the total staff of the hospital. Overall, 6.9% (95% CI of 5.7–8.2) of the hospital staff was serologically positive for SARS-Cov-2, similar in the COVID area –5.7 (3.8–8.1) and non-COVID area –7.2 (5.7–9.0). Age more than 50 years (aOR 2.65; 1.45–4.85) and being in others work category 2.84 (1.34–6.02) were identified as significant predictors of being seropositive. Only 10% of the subjects reported COVID-like illness in the past 1 month.

Conclusion:

The overall modest prevalence of infection among the health care workers, especially non-doctors and nurses, and similarity of prevalence in COVID and non-COVID area staff indicate the possibility of non-hospital source of infection.

Published: December 2020

A detailed analysis of a complete set of the local potentials that appear in the Euler equation for electron density is carried out for noncovalent interactions in the uracil derivative using experimental X-ray charge density. The interplay between the quantum theory of atoms in molecules and crystals and the local potentials and corresponding inner-crystal electronic forces of electrostatic and kinetic origin is explored. Novel physically grounded bonding descriptors derived within the orbital-free quantum crystallography provided the detailed examination of pi-stacking and intricate C=O...pi interactions and nonclassical hydrogen bonds. The donor-acceptor character of these interactions is revealed by analysis of Pauli and von Weizsäcker potentials together with more well-known functions. Partitioning of crystal space into atomic-like potential basins led us to the definite description of the charge transfer. In this way, our analysis throws light on aspects of these closed-shell interactions hitherto hidden from the description.
Kinetic Insights into Cyanosilylation of Aldehydes Catalyzed by a Covalently Bridged Dinuclear (Salen)titanium Complex
Authors: Zhang Zhipeng , Wang Zheng , Ding Kuiling
Published: December 2020

Enantioselective addition of trimethylsilyl cyanide (TMSCN) to aldehydes is one of the most extensively studied organic reactions in asymmetric catalysis. Herein, we report our intensive kinetic investigation on the asymmetric addition of TMSCN to benzaldehyde, catalyzed by a covalently bridged dinuclear (salen)titanium complex 2, which has been one of the most efficient artificial chiral catalysts reported so far for this reaction. It was found that the method of initial rates for kinetic investigation is not appropriate in this case because of the presence of a significant incubation period in the catalysis, while the method of progress rates proved to be more reliable and efficient for judging the kinetic orders of this catalytic system. The kinetic results revealed that the reaction follows first order with respect to the catalyst and is nearly independent of concentrations of both benzaldehyde and TMSCN. A detailed catalytic mechanism for cyanosilylation of benzaldehyde in the presence of 2 was proposed, wherein the key active dinuclear species works in a cooperative manner for dual activation of both reactants.

Published: December 2020

The objective of this study was to evaluate the effects of CEPT for leachate and sewage co-treatment in a POTW. The results showed that ferric and aluminum coagulants remove about 54 - 74% organic matter where ferric performed better than aluminum coagulant. However, ferric coagulant was found to exacerbate the UV absorbance after coagulation at high dose due to the interaction with dissolved organic matter by forming soluble transition metal complexes. These organo-metal complexes have been found to increase the UV absorbance and this study provides the scientific background for such phenomenon.

Aim: The aim of this study was to examine adolescent’s attention levels, in which mood they tend to eat, eating habits and the relationship among them.

Methods: This study was conducted in February 2020 on 142 students in total, 69 (48.6%) of them girls and 73 (51.6%) of them boys who are studying at Süleymaniye Educational Institutions Bağlıca Secondary School in Turkey. Data were collected by a questionnaire with 38 questions and a 24-h dietary recall to determine the personal characteristics and the eating habits of adolescents; the D2 Attention Test was used to determine attention levels and the Emotional Appetite Questionnaire was used to identify appetite.

Results: 38.7% of the participants in the study were overweight and 23.2% were obesity. The D2 Attention test found that mean TN (total number of items processed) and CP (concentration performance) scores were positively correlated with age and negatively with Body Mass Index for age. A significant and negative correlation was found between glucose intake and the TN (total number of items processed) scores.

Conclusions: A high risk of obesity was founded in these secondary school students. At the same time, it is thought that there may be a relationship between individuals' macro and micronutrient consumption and their emotional eating tendency and attention levels. For this reason, it is important to detect and improve dietary habits of adolescence, which is a critical process for future generations.

Authors: Hettiarachchi Charith Amidha
Published: December 2020

The Food Act of 1980 is the main legislation governing food safety in Sri Lanka. Along with its regulations, the act provides a strong basis to ensure safety of food consumed. However, to achieve its objectives, the act needs to be properly implemented. For that, the food industry needs to adhere to food laws while law enforcing officers need to initiate legal proceedings for law violations. A good knowledge on food laws is needed among food industries, law enforcing officers and consumers contributes towards successive implementation of food laws.

The present review examines the available research literature on knowledge on food regulations and practice of food industries, law enforcing officers (Public Health Inspectors) and consumers in Sri Lanka which helps to identify weaknesses in current law enforcement.

Most of research on the Sri Lankan Food Act of 1980 has focused on food labels. Very few labels have been found to conform with existing laws and some include outrageous health claims. Knowledge and practice of food regulations by food industry, law enforcing officers and consumers in Sri Lanka are not satisfactory which has led to a failure in achieving the intended objectives of the legislature.

Published: December 2020

This paper adopts IMU motion recognition technology based on mechanical learning. IMU, inertial measurement unit, is a device that uses accelerometer and gyroscope to measure the three-axis attitude Angle (or angular velocity) and acceleration of an object. In a narrow sense, an IMU is equipped with gyroscope and accelerometer on three orthogonal axes, with a total of 6 degrees of freedom, to measure the angular velocity and acceleration of an object in three-dimensional space, which is known as "6-axis IMU". Broadly speaking, the IMU can add magnetometer to accelerometer and gyroscope to form the "9-axis IMU" which is now known to the public.
Campus Intelligence Mental Health Searching System Based on Face Recognition Technology
Authors: Wang Zixiang
Published: December 2020

The phenomenon of teenage campus suicide has become the focus of attention of parents, schools and the society. The causes behind it are extremely complicated, and the root cause is psychological and spiritual problems. However, one's negative psychology is often hidden, and it is difficult to detect and effectively intervene before the tragedy. How to effectively identify students with suicidal tendencies in order to prevent tragedies has aroused extensive research and discussion among the government, academia and the public. Through investigation and research, it is found that the current popular computer cutting-edge technologies such as artificial intelligence and computer vision can be well used for human emotion recognition and behavior prediction, and put into use in schools as a mental health auxiliary diagnosis and treatment system, thus effectively reducing the suicide rate on campus. The scenario assumes that machine learning can be used to deduce the risk of psychological problems in human samples by analyzing the frequency of negative emotions in facial expressions. Based on this, this paper proposes an effective solution for campus suicide prediction, and designs a set of auxiliary diagnosis and treatment system based on campus monitoring network system for suicide behavior prediction and student mental health analysis. Through preliminary experimental analysis and verification, the suicide psychological auxiliary diagnosis and treatment system has achieved good results in face recognition success rate, emotion recognition success rate and behavior prediction success rate. With the input of more experimental data and the increase of self-training time, the prediction system will perform better.

Published: December 2020

Background: The purpose of this study was to determine whether the occurrence of neonatal idiopathic congenital talipes equinovarus (ICTEV) in Northwest China followed a seasonal pattern and to speculate the potential etiology of ICTEV. Methods: We collected data from 221 children with ICTEV who were born in Northwest China to investigate seasonal variations. We also analyzed seasonal variations in the month of birth and severity. Results: Among male infants with ICTEV, the constituent ratio of children born in May and October was statistically different from that of normal children (OR=1.674, 95%CI, 1.003-2.795, P=0.049; OR=0.041, 95%CI, 0.450-0.968, P=0.041). The months distribution of unilateral and bilateral limb was different (P=0.025). The constituent ratio of bilateral limb in March was higher than that in the other months(P=0.003). Conclusions: This study does not support an in-utero enterovirus infection as the etiology of ICTEV. However, the current research provides strong evidence in support of an unidentified environmental factor influencing the occurrence of ICTEV in the Northwest Chinese population.

Objectives: To study the expression and significance of cyclinD2 and Bcl-2 in diffuse large B-cell lymphoma. Methods: This project used immunohistochemical methods to detect the expression of cyclinD2 and Bcl-2 in 120 cases of diffuse large B-cell lymphoma and 80 cases of reactive hyperplasia of lymphoid tissue. The materials were collected from the hospital from January 2018 to 2020. In March 2015, 120 patients had lymphoma tissue removed during the month of surgery. The postoperative pathological diagnosis was DLBCL. Another 80 cases of lymphoid hyperplasia (RLH) tissues were selected as controls. Results: CyclinD2 and BCL-2 expression were not statistically different in patients with diffuse large B-cell lymphoma in different ages, genders, locations, tissue types, and degree of differentiation; but statistically significant in different Ann Arbor stages, immunotypes, IPI index and first treatment efficacy. Conclusion: This research not only has important theoretical value, but also important economic value and social significance.

Objective: To investigate the diagnostic effects of enhanced CT scan on hemorrhage corpus luteum cyst (HCLC).  Methods: The clinical data of 24 patients with hemorrhage corpus luteum cyst diagnosed by surgery and pathology in our hospital were collected. All patients received enhanced CT scan to evaluate the diagnostic value of CT.  Results: The average diameter of the cysts in this group of patients was 5.1cm by CT. Further detection of the ruptured cyst wall showed that there was a liquid low-density shadow. Some of the cysts were accompanied by signs of increased density, indicating the presence of blood clots; all patients received surgical treatment. Intraoperative ultrasound examination of the cysts had an average diameter of 5.2cm and a wall of 0.2~0.4mm. Among them, 19 cases of cysts contained "coffee-colored" liquid with varying degrees of blood clots, and 5 cases had no blood clots in the cysts but there were a lot of blood clots beside the cysts.  Conclusion: The application of enhanced CT scan in patients with hemorrhage corpus luteum cyst is of great value. It can provide accurate data reference for clinical treatment and is worthy of promoting its clinical application.

The aim of this study was to investigate the implementation of a scientific approach to teaching English in Junior High School in the Indonesian rural areas context. Qualitative method used in this study on pilot project school of 2013 curriculum. The research subject was the English language teacher who has been teaching using the 2013 curriculum. The data then analyzed using Analysis Interactive's Miles, Huberman, and Saldana model. It can be found that the teacher already implements the scientific steps consist of (observing, questioning, collecting data, associating, and communicating). On the other hand, there was still a lot of problem face by the teacher while applying this method, such as a lot of time is spent on this activity, a large number of students, limited time allocation given and also lack of teaching source.Keywords: English Teaching, Implementation, Scientific, Rural Area
Cardiovascular Changes Among Healthy Elderly
Authors: Ikhsan Muhammad , Boy Elman
Published: December 2020

World Health Organization (WHO) defines health as a complete physical, mental, and social well-being and not merely the absence of disease or infirmity. Health is one of the important and valuable values among the elderly. Aging is a progress of life in each individual. Unlike pathological conditions, the aging process will occurs in each individual. Elderly tend to experience physical, mental, and spiritual deterioration. The health status of each individual can have an impact on changes in cardiovascular function in the elderly. After each individual reaches the age of 30, heart-lung fitness decreases by 1% for each age, which increases by one year. At the age of 60, heart-lung fitness will decrease until 35%. The aim of conducting this literature review is to provide an understanding of the cardiovascular changes among healthy elderly. The main effects aging on the cardiovascular system are a changes in vascular structure, a decrease in vascular function, myocytes and atrial pacemaker cells, an increase in cardiac fibrous tissue, a decrease in the function of the ventricular, myocardial contraction, and cardiac output which results in impaired cardiovascular fitness among elderly.

This study aims to determine the effect of the principal's digital leadership on vocational teachers' reflection practice, mediated by the variables of trust, self-efficacy, and work involvement. This study uses path analysis with modeling using SEM (AMOS). The sample of this research is 637 (N=340 females and N=297 males) vocational high school teachers in Malang Raya, East Java, Indonesia. The researchers have used a purposive random sampling technique to meet the objectives of this research. The investigators have used a 86 item questionnaire to collect data on the studied variables. Based on the fit model's estimation, there is a direct and indirect relationship between the five variables used. The variables of trust, self-efficacy, and job involvement contributed significantly to intervening variables. It can be concluded that the moderating variable strengthens the framework for the relationship between digital leadership and teacher reflective practices. The new relationship formed is a direct contribution of digital leadership to work engagement with a magnitude of 0.120 and a direct relationship made between digital leadership and the reflective practice of teachers of 0.168. This relationship has a positive impact on teacher actions. These results indicate that the teacher appreciates the Principal's leadership, who both supports facilitates the learning process in using technology in the learning process. Moreover, teachers feel motivated and excited to reflect on their learning because of the leaders who have digital characters. The teacher considered leaders with digital personalities more open and tended to free them to manage the class.

Как только завершено исследование и подготовлена рукопись, авторы по по- нятным причинам хотят, чтобы их работа была опубликована и доступна для про- чтения и восхищения как можно скорее. Это стремление к быстрой публикации является одним из стимулов, к которому прибегают хищнические журналы, чтобы уговорить неосторожных авторов представить свои работы и оплатить взнос за пу- бликацию статьи. Недавно я получил электронное письмо, где мне предлагали опу- бликовать свою работу в течение 48 часов после ее отправки!

Authors:   Edinburgh Napier University, Edinburgh, UK, Cowan John
Published: December 2020

The case is presented for the role of anticipatory reflection in the development of graduate attributes by employed graduates and in the enhancement of core study skills by students. An approach initiated by reflection-for-action and the stimulus of subsequent evidence-based monitoring leading into reflective review has been found feasible and effective. After relevant literature has been considered, recent accounts of the approach and its impact are summarised, leading into a detailed summary of the suggested scheme in a form which is independent of discipline and embodies the assessment of outcomes. Attention is given to the emergence of constructive active experimentation and metacognition by learners during the development process.
