Wearable RF Near-Field Cough Monitoring by Frequency-Time Deep Learning.

Coughing is a common symptom for many respiratory disorders, and can spread droplets of various sizes containing bacterial and viral pathogens. Mild coughs are usually overlooked in the early stage, not only because they are barely noticeable by the person and the people around, but also because the present recording method is not comfortable, private, or reliable for long-term monitoring. In this paper, a wearable radio-frequency (RF) sensor is presented to recognize the mild cough signal directly from the local trachea vibration characteristics, and can isolate interferences from nearby people. The sensor operates at the ultra-high-frequency band, and can couple the RF energy to the upper respiratory track by the near field of the sensing antenna. The retrieved tissue vibration caused by the cough airflow burst can then be analyzed by a convolutional neural network trained on the frequency-time spectra. The sensing antenna design is analyzed for performance improvement. During the human study of 5 participants over 100 minutes of prescribed routines, the overall recognition ratio is above 90% and the false positive ratio during other routines is below 2.09%.

RETRACTED ARTICLE: Security management in smart home environment

A smart home environment comprises various luxurious things which makes us very comfortable to live our lives happily and securely. The only problem that smart homes are facing is “SECURITY.” Security for smart homes is the biggest task to achieve. For this purpose, this work is to build a product that provides the security for the smart homes automatically when the crime is going to happen. In general case, if any crime had taken place in any smart home, the general procedure of investigation will take place i.e., the people will complain to the police and the police will visit the place and after that he will observe the surroundings clearly. In order to pull up the clues if any, he will watch the closed circuit television (CCTV) footage, consult the nearby people in-order to draw some facts and then first information report will be filed. In order to get rid of this time-consuming process, automatic crime detection is proposed. Here malware practices are identified, when a person attempts crime activity. This type of automatic process of detection of crime will ensure a complete security for the smart homes. We will track the CCTV camera pictures when the thief is trying to commit a crime and the information along with the pictures will be sent to the fog server and the fog server will analyze whether the person is doing crime or not. In case if a fog server had identified the person as a crime person or a thief then it automatically sends the information to the nearby police station and as well as owners of the house and then provides security for the smart homes.

Report of Nesting of the Bananaquit (Passeriformes, Thraupidae, Coereba flaveola) in Man-made Objects in the Dominican Republic

Two nests of Bananaquit (Coereba flaveola) were observed in man-made objects in a suburban area of Jarabacoa, Dominican Republic. The nests were located at the base of rustic pendant lights made of metal, placed on a second-floor terrace of an inhabited dwelling. One nest contained three chicks, while the other was empty. An adult made several approaches to the breeding nest to feed the chicks, despite the presence of people nearby. The selection of these nesting sites is probably due to protection against adverse environmental conditions and predators, since both were located under a roof.

Characterization of Pyrolytic Oil Produced from Waste Plastic in Quezon City, Philippines Using Non-catalytic Pyrolysis Method

Due to massive amount of waste plastics in different dumpsites, our community suffers and also the environment. Thus, affects nearby people with problems with plastic wastes. One of the processes to lessen these wastes is through pyrolysis of which fuel oil can be produced. The study involved the production of fuel oil from waste plastics taken from the Payatas dump site in Quezon City, Philippines. After thorough cleaning, the waste plastics were shredded thru mechanical means and underwent pyrolysis. Given the available thermal chamber facility in ITDI-DOST in Taguig City, Philippines, pyrolysis of waste plastics produced fuel oil in varying per cent yield from the different types of plastic. Characterization of the oil sample was conducted such as ash content, carbon residue, copper corrosion strip, flash point, pour point, sulfur, kinematic viscosity, specific gravity water and sediments that were based from the PNS/DOE QS 006-2005. The oil sample was analyzed using different laboratory tests following the methods of the American Society for Testing and Materials (ASTM). Using this standards, the analysis of the oil sample gave the positive results in comparison to the specifications set by the Philippine National Standard and was classified as fuel oil. Pyrolytic oil from waste plastic can be an alternative fuel source.

MO827ASSESSMENT OF SARS-COV-2 ANTIBODIES IN PATIENTS ON HEMODIALYSIS

Background and AimsStrategies to minimize the risk of transmission of coronavirus disease 2019 (COVID-19) infection in hemodialysis (HD) patients have been rapidly implemented worldwide (Nature 16: 311, 2020). Serological testing of 356 HD patients revealed that 129 (36.2%) patients were positive for SARS-CoV-2 antibodies. Out of these 129 patients, 52 (40.3%) patients were asymptomatic (JASN 31:1969, 2020). In this study, we investigated the seroprevalence of SARS-CoV-2 antibodies in HD patients who were managed per Japanese Society for Dialysis-Therapy guidelines in the context of COVID-19.MethodStudy (1): A total of, 55 patients that underwent HD (41 males, 14 females; mean age: 66.3±12.8 years, HD duration: 72.2±68.4 months) between August 1 and December 14, 2020, were included. We measured SARS-CoV-2 antibodies with a fully automated cobas e801 analyzer using an Elecsys® Anti-SARS-CoV-2 electrochemiluminescence immunoassay (Roche Diagnostics) to qualitatively detect SARS-CoV-2 antibodies in human plasma. The Elecsys® assay uses a modified double-antigen sandwich immunoassay with recombinant nucleocapsid protein (N), which is geared towards the detection of late, mature, high-affinity antibodies independent of the subclass. Study (2): We tested the plasma of 8,982 adult with normal renal function for SARS-CoV-2 antibodies between July 1 and November 18, 2020.ResultsStudy (1): Using serological testing, only 2 out of 55 (3.64%) HD patients tested positive for SARS-CoV-2 antibodies. In total 54 patients were asymptomatic during the study period and did not have a polymerase chain reaction (PCR) test. Only 1 out of the 54 (1.85%) patients that were asymptomatic had SARS-CoV-2 antibodies. Case 1 was an 89-year-old, male who had undergone HD for 53 months because of end stage kidney disease (ESKD) secondary to diabetic nephropathy. His blood type was O Rh (+). This patient tested positive for SARS-CoV-2 antibodies on August 11, 2020. Serological testing showed that this patient had an asymptomatic disease. Case 2 was a 74-year-old, male that had undergone HD for 62 months due to ESKD secondary to diabetic nephropathy. He was hospitalized because of bradycardia-tachycardia syndrome on November 14, 2020. On that day, his PCR test was negative. He underwent surgery to insert a cardiac pacemaker on November 18, and had a fever (37.7°C) on November 24. A chest CT scan revealed that he had bilateral lung pneumonia. On that day, his PCR test was positive. Blood tests showed that his white blood cell count was 4300/μL (lymphocyte 30.4%), and C-reactive protein (CRP) levels was 2.8 mg/dL. He was not treated with antiviral medication, the PCR test was repeated and was positive on December 4,7, and 9. However, his PCR test was negative on December 13. This patient tested positive for SARS-CoV-2 antibodies on December 14. He recovered from a COVID-19 infection 21 days after the onset of the disease. Study (2): Using serological testing, 47 out of 8,982 (0.52%) adults tested positive for SARS-CoV-2 antibodies. In Japan, the population of Kanagawa prefecture is 9,216,009. The number of PCR-confirmed patients with COVID-19 infection was 13,340 (0.14%) on December 6, 2020. The estimated number of asymptomatic SARS-CoV-2 infection was 47,923 (0.52%). The total estimated number of patients with COVID-19 infection was 61,263. In study 1, more than 90% of HD patients wear face masks, wash their hands, and maintain social distance of 2 m in dialysis facilities. Almost all patients avoided the three Cs (closed spaces with poor ventilation, crowded places with nearby people, close-contact settings, such as close-range conversations).ConclusionWe found that Japanese patients on HD had a lower prevalence of SARS-CoV-2 antibodies compared to those in the United Kingdom. Serological testing identified HD patients with asymptomatic disease. Avoiding the ‘three Cs’ is very important in minimizing the risk of COVID-19 among HD patients.

Gender and the privacy paradox in Chinese college students’ locative dating communication

This article explores the role gender plays in addressing the privacy paradox in the context of young Chinese people’s locative dating communication. Based on a case study of 19 Chinese college students, I explore differing privacy management strategies adopted by female and male participants in their use of WeChat People Nearby. This gendered phenomenon reveals how People Nearby works within patriarchal Chinese society to pose more privacy-related risks to women than to men in locative dating communication. The research findings shed new light on the socio-technological processes through which existing gender power relations are reproduced in young Chinese people’s use of locative social media applications.

The Impact of Partner Phubbing on Marital Quality among Married Couples in Malaysia: Moderating Effect of Gender and Age

Abstract. Smartphones and the internet have indeed revolutionized our lives in innumerable ways, among them the emergence of a social phenomenon called ‘phubbing.’ Phubbing is a portmanteau combining the words “phone” and “snubbing”. A person engaging in “phubbing” interacts obsessively with his/her phone rather than communicating with nearby people. Partner phubbing (Pphubbing) is defined as phubbing behaviour when in the presence of one’s spouse or significant other. The aim of this study is to explore the relationship between Pphubbing and marital quality, and to investigate the moderating role of gender and age in this relationship. The participants in the survey were 390 married adults living in Kuala Lumpur. The respondents were selected randomly and volunteered to answer a series of questionnaires made up of the Partner Phubbing Scale, the Dyadic Adjustment Scale and a section on demographic data. Results showed that Pphubbing behaviour has a significant negative relationship with marital quality. Moreover, gender and age were found to have significant moderating effects on the relationship between Pphubbing and marital quality. The reported impact of Pphubbing on marital quality was stronger among females than males, and the effects were also stronger among younger adults. These findings may have implications for family and couple counselling and for the coaching profession. Future research should be done to address this phenomenon more thoroughly. Keywords: interpersonal communication; marital quality; partner phubbing; phubbing; relationship

Blood Pressure, Heart Beat and Body Temperature Measurement by Using GSM and Low-Cost Microcontroller with Health Care Announcement

The movement of aged people or physically handicapped people and the people suffering from some serious diseases are usually confined to their homes and the other live with that chronic disease out of home, due to their health conditions. They are placed into a helpless or unable condition when they need to go out play with their friends and also not allowed for small tasks to do and totally placed in unworthy condition. This paper deals with The Design and Development of an Arduino based Microcontroller and GSM network Enabled Embedded System for Blood Pressure, Heart Beat and Body Temperature Monitoring, and Body balance and flexing system with ECG Signal Monitoring and The proposed system uses GPRS mobile communication system to check the patient’s abnormality within that of simulated biomedical parameters result. The normal or abnormal change in the values of reading in any of these parameters from their current reading values will be sensed immediately and health care help is given by the nearby people of family member or doctor. If there is no health care or help, the system sends a GPRS message directly to a family member, doctor, or caretaker’s mobile phone. It is a bi-directional communication system in which the caretaker/doctor, at any time, can send SMS to know the present status of a patient.

Condition of Seawall and Problems Faced by People in Vypin Island

Vypin is one of the groups of islands that form part of the city of Kochi, in Kerala state of Ernakulam district with around 27 kilometres. This island was formed in 1341 followed by heavy floods and now it is one of the famous tourist places in the state. Edavanakkad, Elamkunnappuzha, Kuzhuppilly, Nayarambalam, Njarakkal and Pallippuram are the panchayaths in Vypin and all the panchayaths are having a part in them which connected to see. The condition of the seawalls in all the regions within Vypin is different. Problems with seawall are directly affecting the lives of people at the seaside. They are not able to live other than the seaside due to their job that is fishing. So, they are forced to live nearby the sea and their life being risky due to lack of maintenance and in some places, there is no seawall at all. This paper could bring some attention to authority and may use for any further detailed study and action plans. By direct observation, we can find the condition of the seawall in each area and also it is important that the area which is famous or considered as a tourist spot the walls are well maintained but still the people nearby that area is facing problems with pollution. The other parts in which the walls are in very pathetic condition and some there are no walls which is a serious issue. By interacting with the people who suffering can give a clear picture of what they facing. This study may help to know the problems faced by seaside people and also may help to make policies to improve their conditions.

FIRST REPORT ON HUNTING BEHAVIOR OF MIGRATORY ORIENTAL HONEY-BUZZARD (PERNIS PTILORHYNCHUS ORIENTALIS) TOWARDS MIGRATORY GIANT HONEYBEE (APIS DORSATA DORSATA) (HYMENOPTERA: APIDAE) ON JAVA ISLAND, INDONESIA

Both Migratory Oriental Honey-buzzard (Pernis ptilorhynchus orientalis) and migratory giant honeybee (Apis dorsata dorsata) can be found in South-east Asia. The Oriental Honey-buzzard is the main predator of the giant honeybee, prey upon its honeycomb, larvae, and honey. Its existence always follows the migration of the giant honeybee. They stay on Java island during the migratory season. The giant honeybee lives in a large colony and has a powerful sting that is useful for defence against its predators. The bee is among the most dangerous animals since its threatening defensive behavior causes severe impact on the eagle and is even frequently fatal for human beings. Data collections on hunting behavior of the Oriental Honey-buzzard were based on irregular observations and interviews between the year 2003 to 2019. We categorized five hunting behaviors during data collections: flying orientation around the bee’s nest, attack on living nest, failure to collect the living nest, preying upon the newly empty nest, and transferring attack of the angry bee to people nearby. The safest hunting for the Oriental Honey-buzzard is to prey upon newly empty nest left by the honeybee. When the nest was still occupied by the bee colonies, the eagle should develop a strategy to avoid and reduce the risk of being attacked. It sometimes transfers the attack to people nearby.

In-Vitro analysis of medicinal plant for anti-inflammatory properties

This examination demonstrations the in vitro mitigating impact of leaf concentrates of Polyalthia longifolia. These were investigated in various measures to decide their mitigating impacts. Protein denaturation and RBC film adjustment were measured. The outcomes were accounted for as % hindrance in triplicate assurance and were exposed to factual additionally, diclofenac Aspirin and sodium were utilized as norms. The consequence of the % restraint of protein denaturation demonstrated that at 1mg/ml diclofenac, ethanolic extricate, new leaf fluid concentrate and dry leaf watery concentrate. Because of dissecting the MS and UV information and in contrast with the legitimate norms, an aggregate of 10 polyphenols were recognized and measured, counting gallic corrosive, catechin, quercetin, kaempferol, and their subordinates. This is the primary investigation looking at the leaves, as opposed to the organic product or seeds reasonably collected yet underutilized by nearby indigenous people groups. The concoction outline of the leaf was thoroughly broke down and prompted the ID of 10 polyphenol mixes, counting phenolic corrosive and flavonoids. The individual polyphenols were effectively quantitated, utilizing UV recognition. Additional bioactivity examinations demonstrated that the concentrates of leaf display cancer prevention agent, antiproliferation, and calming exercises. The primary atomic component may mostly be donated by the hindrance of NF-κB enactment, a typical sign alleyway among multiplication and aggravation. Additional examinations are expected to investigate whether these polyphenol mixes could work synergistically to accomplish significantly better exercises than each solitary segment. The concoction bioactivities and profile decided to help its conventional usage and might assistance for its additional pharmacological investigations and nutraceutical requests.

A Privacy-Preserving Mobile and Fog Computing Framework to Trace and Prevent COVID-19 Community Transmission.

To slow down the spread of COVID-19, governments worldwide are trying to identify infected people, and contain the virus by enforcing isolation, and quarantine. However, it is difficult to trace people who came into contact with an infected person, which causes widespread community transmission, and mass infection. To address this problem, we develop an e-government Privacy-Preserving Mobile, and Fog computing framework entitled PPMF that can trace infected, and suspected cases nationwide. We use personal mobile devices with contact tracing app, and two types of stationary fog nodes, named Automatic Risk Checkers (ARC), and Suspected User Data Uploader Node (SUDUN), to trace community transmission alongside maintaining user data privacy. Each user's mobile device receives a Unique Encrypted Reference Code (UERC) when registering on the central application. The mobile device, and the central application both generate Rotational Unique Encrypted Reference Code (RUERC), which broadcasted using the Bluetooth Low Energy (BLE) technology. The ARCs are placed at the entry points of buildings, which can immediately detect if there are positive or suspected cases nearby. If any confirmed case is found, the ARCs broadcast pre-cautionary messages to nearby people without revealing the identity of the infected person. The SUDUNs are placed at the health centers that report test results to the central cloud application. The reported data is later used to map between infected, and suspected cases. Therefore, using our proposed PPMF framework, governments can let organizations continue their economic activities without complete lockdown.

Interface culture and gendered privacy risks in the context of Chinese locative social media use

ABSTRACT Across the world, young people are increasingly using locative social media applications to socialize with strangers for dating opportunities. This phenomenon is also found in Chinese society, where such applications are very popular with young Chinese urbanites. This article presents a case study of how young Chinese urbanites navigate social interactions with strangers on WeChat People Nearby, based on the findings of interviews with 19 Chinese university students aged between 18 and 23. By drawing on the notion of interface, we uncover how gender dynamics are established in young Chinese urbanites’ People Nearby use and how the gender dynamics are engineered by the privacy paradox of interfaced social interactions between strangers in the locality. The outcomes of the present research help us to understand the gender-related opportunity-risk axis established in young Chinese urbanites’ everyday use of locative social media applications.

Calling from the outside: The role of networks in residential mobility

Using anonymised cellphone data, we study how social networks shape residential mobility decisions. Individuals with few local contacts are more likely to change residence. Movers strongly prefer neighbourhoods where they already know more people nearby. Contacts matter because proximity to them is valuable and makes attractive locations more enjoyable. They also provide hard-to-find local information and reduce frictions, especially in home-search. Effects are not driven by similar people being more likely to be friends and move between certain locations. Recently-moved and more central contacts are particularly influential. With age, proximity to family gains importance over friends.

COVID-19: Concern and Education for Global Health for a Have-to Traveler

COVID-19, a severe respiratory disease mediated by SARS-CoV-2 virus, is an extremely infectious. This virus was a recant outbreak from Wuhan City of China in late December 2019, but no remedy has been found yet. The coronavirus can spread mainly from person to person when they come in close contact with each other. Respiratory droplets from an infected person’s infect any nearby people. Furthermore, asymptomatic person can also infect others. Data and information were searched from Web Science, Google Scholar, and PubMed databases, and the articles published before June 2020, using relevant keywords. WHO, CDC and other Govt. Agencies have published a protective measure for better prevention of the COVID-19 disease until vaccines or any other antivirals become available. “Stay at home”, “Uses of Mask”, and “Wash hands frequently for 20 sec” are some of the general strategy for precaution. However, it is not possible for the ‘must travellers’ and/or “front-line workers” to “stay at home”. The concerns of the must-travellers and front-line workers to avoid any unwanted consequences that may arise from their travelling issues were discussed in this review.
