ABSTRACT Objectives: There is a lot of speculation, debate, and hypothesis about the new coronavirus disease 2019 (COVID-19) severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Also the world famous media British Broadcasting Corporation (BBC), National Center for Biotechnology Information (NCBI), and World Health Organization (WHO) are informing their emergency concern for the public attention. But we are far behind yet to say the origin of COVID-19 and its outbreak. The main purpose of this study is to put an end to all speculations, fantasies, theories and debates.

Abstract: COVID-19 pandemic has rapidly affected our day-to-day life the world trade and movements. Wearing a face mask is very essentials for protecting against virus. People also wear mask to cover themselves in order to reduce the spread of covid virus. The corona virus covid-19 pandemic is causing a global health crisis so the effective protection method is wearing a face mask in public area according to the world health organization (WHO). The covid-19 pandemic forced government across the world to impose lockdowns to prevent virus transmission report indicates that wearing face mask while at work clearly reduce the risk of transmission .we will use the dataset to build a covid-19 face mask detector with computer vision using python,opencv,tensorflow,keras library and deep learning. Our goal is to identify whether the person on image or live video stream is wearing mask or not wearing face mask this can help to society and whole organization to avoid the transfer of virus one person to antother.we used computer vision and deep learning modules to detect a with mask image and without mask image. Keywords: face detection, face recognition, CNN, SVM, opencv, python, tensorflow, keras.

Purpose With encouragement from the World Health Organisation, national suicide prevention policies have come to be regarded as an essential component of the global effort to reduce suicide. However, despite their global significance, the construction, conceptualisation and proposed provisions offered in suicide prevention policies have, to date, been under researched; this study aims to address this gap. Design/methodology/approach we critically analysed eight contemporary UK suicide prevention policy documents in use in all four nations of the UK between 2009 and 2019, using Bacchi and Goodwin’s post-structural critical policy analysis. Findings The authors argue that across this sample of suicide prevention policies, suicide is constructed as self-inflicted, deliberate and death-intentioned. Consequently, these supposedly neutral definitions of suicide have some significant and problematic effects, often individualising, pathologising and depoliticising suicide in ways that dislocate suicides from the emotional worlds in which they occur. Accordingly, although suicide prevention policies have the potential to think beyond the boundaries of clinical practice, and consider suicide prevention more holistically, the policies in this sample take a relatively narrow focus, often reducing suicide to a single momentary act and centring death prevention at the expense of considering ways to make individual lives more liveable. Originality/value UK suicide prevention policies have not been subject to critical analysis; to the best of the authors’ knowledge, this study represents the first attempt to examine the way in which suicide is constructed in UK suicide prevention policy documents.

COVID-19 was declared a global pandemic by the World Health Organization in 2020 with countries putting up several measures to mitigate and flatten the curve of hospitalizations and death from travel bans to home confinements and local lockdowns. This pandemic created health and economic crises, leading to increased incidence of poverty and food crisis especially on both agriculture and the fisheries in many developing nations including the Philippines. The specific objectives of this study were to assess the impact of COVID-19 restrictions on the catch per unit effort (CPUE) of small-scale fishers and to determine what factors could influence the volume of their catch during this time of pandemic. Moreover, this also investigated the impact of COVID-19 restrictions to fishers and their families. To do that we surveyed N = 200 small-scale fishers around the Davao gulf using semi-structured questionnaire and inquired on the impact of the COVID-19 to their fishing operation, catch, fishing costs, and their families. The collected socioeconomic variables, including emotional responses to the pandemic were then related to the CPUE and the volume of catch. The results show that fishers were highly affected by the pandemic due to the lockdown policy imposed in the fishing villages during the earlier phases of restrictions by the government. Fishers were affected in terms of the volume of their catch, also fishing costs, and emotionally as they were also frustrated due to the impacts of the hard lockdown. The restricted fishing access was found to have important and major set-back on the fishing operations of fishers and the same was experienced also by the middlemen given the low fish price and reduced mobility of the fish traders. COVID-19 also impacted the fishers, and their families through lack of mobility, food inadequacy, travel restrictions and their children’s education.

WHO (World Health Organization) telah menetapkan wabah COVID-19 sebagai pandemi tingkat global karena tingkat penyebaran COVID-19 yang sangat cepat hampir ke seluruh dunia. Protokol kesehatan seperti menjaga jarak, mencuci tangan, dan rutin menggunakan masker menjadi langkah untuk meminimalkan penyebaran virus COVID-19. Penggunaan masker menjadi kebiasaan baru yang erat dengan keseharian setiap orang saat ini. Masker yang dipakai dalam jangka waktu yang lama ternyata dapat menimbulkan beberapa permasalahan pada kulit seperti jerawat, dermatitis, kemerahan dan pigmentasi pada wajah.  Keluhan kulit yang paling banyak terjadi pada tenaga kesehatan yang menggunakan masker adalah akne. Oleh sebab itu, kami memilih topik tersebut dengan tujuan untuk mengedukasi masyarakat mengenai cara menjaga kesehatan kulit di masa pandemi dan bagaimana pencegahan serta penatalaksanaan mask-acne. Dalam masa pandemi, upaya untuk melakukan edukasi kepada masyarakat dilakukan dengan memanfaatkan fitur Instagram Live yang dapat mempermudah masyarakat untuk menjangkau informasi dan menjadi media platform yang banyak digunakan oleh masyarakat. Metode edukasi ini dilakukan secara daring dengan menggunakan platform sosial media Instagram yang dilakukan sebanyak 3 (tiga) kali intervensi. Intervensi pertama kami melakukan kuis fakta dan mitos seputar kesehatan kulit dan mask-acne dengan total 868 responden, serta melakukan pre-test yang diisi oleh 50 responden. Intervensi kedua adalah melakukan Instagram Live berupa talkshow atau QnA bersama dermatovenereologist FK UNAIR/RSUD Dr. Soetomo Surabaya, dengan penonton sejumlah 267 pengguna dan telah ditonton ulang sebanyak 263 pengguna. Pada intervensi akhir, terdapat sesi post-test yang diisi oleh 50 responden yang didapatkan peningkatan hasil nilai terhadap pemahaman topik. Evaluasi kegiatan ini didapatkan dari kuesioner yang dibagikan kepada para peserta dan menunjukkan mayoritas responden memberikan umpan balik yang sangat baik terhadap materi yang dibawakan (58-68%), kesesuaian materi terhadap kondisi pandemi (60-70%), serta kebermanfaatan acara (68-74%).

Background: According to World Health Organization, proportion of women experiencing either physical or sexual violence ranges between 15% and 17%. In India, one-third of women population in 15 to 49 age group experiences sexual assault at least once in their life, predisposing them to develop psychiatric disorders. Aims and Objectives: To assess prevalence of psychiatry disorders among victims of assault attending tertiary care center. Methodology: It is a retrospective, record-based study which was conducted among 216 victims of assault attending one-stop center. Study was started after obtaining Institutional Ethical Committee clearance and permissions from concerned authorities and confidentiality was maintained throughout the study. Data was analyzed by frequency, proportion, and chi-square tests using SPSS version 16. Results: Out of 216 victims, 50% were physically assaulted and 50% were sexually assaulted. Among 108 sexual assault cases, 81.5% victims were raped, 2.7% were sexually harassed, 1.9% was sexually abused, and 13.9% children were sexually abused. A total of 30.1% had adjustment disorder, 11.6% had dysthymia, 8.3% had mild depression, 5.6% had moderate depression, 0.5% had obsessive-compulsive disorder, 0.5% had psychosis, and 43.5% did not have any psychiatry disorder. Conclusion: Majority of the sexually assaulted victims belonged to age group 16 to 20 years and had adjustment disorder, whereas physically assaulted victims belonged to age group above 36 years and had dysthymia and depression. Special services like medical care, counseling, legal aid, and so on should be provided to victims free of charge. Awareness and sensitization programs should be done through active community participation for the welfare of children and women.

Electrochemical detection of metal cations at paper-based sensors has been suggested as an attractive alternative to current spectroscopic and chromatographic detection techniques due to the ease of fabrication, disposable nature, and low cost. Herein, a novel carbon black (CB), dimethylglyoxime (DMG) ink is designed as an electrode modifier in conjunction with 3-electrode inkjet-printed paper substrates for use in the adsorptive stripping voltammetric electroanalysis of nickel cations in water samples. The developed method provides a novel, low-cost, rapid, and portable adsorptive stripping detection approach towards metal analysis in the absence of the commonly used toxic metallic films. The study demonstrated a novel approach to nickel detection at paper-based sensors and builds on previous work in the field of paper-based metal analysis by limiting the use of toxic metal films. The device sensitivity is improved by increasing the active surface area, electron transfer kinetics, and catalytic effects associated with non-conductive dimethylglyoxime films through CB nanoparticles for the first time and confirmed by electroanalysis. The first use of the CB-DMG ink allows for the selective preconcentration of analyte at the electrode surface without the use of toxic Mercury or Bismuth metallic films. Compared to similarly reported paper-based sensors, improved limits of detection (48 µg L-1), selectivity, and intermetallic interferences were achieved. The method was applied to the detection of nickel in water samples well below World Health Organization (WHO) standards.

We analyzed the synchronized movements of lumber futures and southern pine sawtimber stumpage prices in the United States since 2011 and their response to COVID-19 events using wavelet analysis and event study. We found that the sawtimber and lumber prices have followed complex comovement patterns in the time-frequency domain and both reacted to COVID-19 events with a higher response intensity of the lumber price. Although they reacted differently to the early COVID-19 episodes and vaccine news, the sawtimber and lumber prices responded similarly to the COVID-19 pandemic declarations by the World Health Organization and US president, the US Food and Drug Administration panel’s recommendation of the first COVID-19 vaccine, and economic stimulus legislation. The patterns of synchronized movements between the sawtimber and lumber prices varied with time and frequency, but their comovement at low frequencies (>64 weeks) has strengthened since 2014 and been led by the lumber futures price; COVID-19 episodes have not changed this trend. The different magnitude of response of the two prices to the COVID-19 related events, as well as the long-term dominance of the lumber price in the comovement, reveals asymmetric price negotiation power and benefit distributions among the agents of the lumber value chain.
