Authors: Aminah Siti
Published: September 2022

AbstrakPada umumnya  masalah yang sering terjadi dalam pembelajaran Kimia adalah rendahnya minat Peserta didik dalam pembelajaran kimia. Minat peserta didik yang rendah dapat disebabkan karena sebagian besar siswa menganggap kimia sebagai pelajaran yang sulit dan membosankan. Hal ini mengakibatkan rendahnya hasil belajar kognitif Peserta didik dalam pembelajaran Kimia. Selain itu, faktor lain yang menyebabkan rendahnya minat peserta didik yaitu proses pembelajaran yang masih didominasi oleh cara konvensional.  Oleh karena itu untuk mengatasi masalah tersebut diperlukan model pembelajaran yang dapat membangkitkan minat dan semangat siswa. Problem Based Learning merupakan konsep belajar yang menggunakan masalah sebagai konteks bagi siswa untuk belajar tentang cara berfikir kritis, keterampilan pemecahan masalah, dan untuk memperoleh konsep yang esensial dari materi pelajaran. Model pembelajaran Problem Based Learning ini berorientasi pada masalah termasuk belajar. Tugas guru disini sebagai motivator, fasilitator dan pembimbing siswa yang mengalami kesulitan agar siswa menjadi lebih aktif dan kreatif sehingga dapat meningkatkan hasil belajar. Untuk mengetahui apakah model pembelajaran Problem Based Learning dapat meningkatkan hasil belajar Peserta didik, maka dilakukanlah penelitian Tindakan kelas  (PTK).

Published: September 2022

Исследованы рост и расположение деформационных полос в очаге деформации (полосе Чернова-Людерса) при растяжении образцов стали 09Г2С, испытавших нормализацию, с использованием метода корреляции цифровых изображений. Проведена оценка скоростей продольного (вдоль оси нагружения) и поперечного роста деформационных полос и очага деформации. С помощью просвечивающей электронной микроскопии исследована дислокационная структура внутри первой деформационной полосы до ее пересечения второй полосой. Показано, что поочередно возникающие полосы деформации попарно пересекаются в середине образца и в зародышевых центрах, находящихся вблизи ребер плоского образца, в результате чего формируется их фермообразное расположение.

Published: September 2022

Разработана компьютерная модель процессов кристаллизации многокомпонентных сплавов на основе алюминия при лазерной обработке. Проведено моделирование кристаллизации сплава при разных параметрах: размерах области построения, количестве актов зарождения и роста зерен, максимальном общем количестве актов в системе. Компьютерная модель имеет хорошую воспроизводимость результатов и позволяет определять такие параметры структуры, как средний размер зерна, коэффициент формы, долю закристаллизовавшегося объема в процессе кристаллизации. С помощью разработанной модели можно проводить расчет кристаллизации в условиях наличия эпитаксиального слоя (подложки), что дает возможность оценить влияние параметров кристаллизации на формирование в структуре зоны столбчатых кристаллов и провести их оптимизацию.

Chile: revuelta social en el neoliberalismo avanzado
Authors: Ruiz Encina Carlos
Published: September 2022

Se analiza la revuelta social chilena bajo la profundidad y duración de la transformación neoliberal, y la especificidad del sujeto popular que emerge de las contradicciones y conflictos propios de dichas condiciones. Se discute el carácter de la crisis y su origen en tales condiciones sociales y culturales, antes que, en una crisis económica o política coyuntural, a diferencia de otras experiencias regionales. Se revisan los cambios de la estructura social chilena, de clases y grupos sociales en las últimas décadas, y los nuevos conflictos y polaridades ligadas a ello. Se aborda la incapacidad de la esfera política para procesar tal conflictividad y su desborde, propia de una crisis de legitimidad en curso. Finalmente, se propone que allí subyacen las condiciones sociales, políticas y culturales para el surgimiento de un nuevo pueblo, capaz de abrir un nuevo ciclo histórico, cuya especificidad lo distingue de aquel que en el siglo XX enfrentó al viejo orden oligárquico-agrario.
Resumen de tesis: Procesos extractivos, territorios urbanos y conflictos territoriales
Authors: Heredia Chaz Emilce
Published: September 2022

Es un resumen de una Tesis doctoral
El propósito de la tesis fue analizar la relación entre la ciudad de Bahía Blanca y un polo petroquímico recientemente privatizado, extranjerizado y ampliado, entre los años 1995 y 2002, indagando las dinámicas a través de las cuales los procesos extractivos intervinieron en la (trans)formación del territorio urbano. Nuestra hipótesis de trabajo planteaba que, bajo la territorialización de los procesos extractivos, en las ciudades se genera la apropiación capitalista de bienes comunes naturales y urbanos como, así también, de excedentes por medio de la configuración de enclaves económicos, produciéndose un desarrollo que se revela como destructivo y en torno al cual se producen diversos procesos de conflictividad. Para trabajar sobre dicha hipótesis, partimos desde la historia urbana, recuperando su carácter interdisciplinario y multidimensional, y establecimos diálogos con la nueva historia local y regional y la historia del presente con el propósito de enriquecer las escalas espaciales y temporales de estudio.

Authors: Tiara Adinda Ratih , Rusady Yulia Paramita
Published: September 2022

The process of childbirth often results in tearing of the birth canal which causes bleeding in varying amounts. One source of bleeding that comes from perineal wounds that require optimal care. Based on data obtained from the Polindes Marengan Laok, it showed that 7 postpartum mothers (70%) had their perineal wounds in 1 week still wet, moist, some even had pus. The purpose of this study was to determine the effect of vulvar hygiene on the healing of perineal wounds on the 7th day of postpartum women.

This type of research is correlation analytic. Based on the time this research uses cross sectional. The independent variable is vulva hygiene and the dependent variable is perineal wound healing. The population is 30 postpartum mothers in Marengan Laok Village with a total sampling technique. Data collection techniques using questionnaires and checklists.

Based on the cross tabulation, almost all respondents who performed vulvar hygiene well (88.2%) had their perineal wounds healed as many as 15 respondents, and respondents who lacked vulva hygiene mostly (62.5%) did not heal perineal wounds as many as 5 respondents. From the statistical test of the contingency coefficient using SPSS 18, it was found that 2 count > 2 table (7,297 > 5,991). Based on the coefficient value (0.442) there is a moderate relationship between vulva hygiene and healing of perineal of postpartum women in the Marengan Laok Village.

Based on these conclusions, the solution that can be done is that health workers should further improve postnatal services, especially in conducting home visits to prevent, detect, and treat problems in the perineal wound healing process.

Can gender approaches to promote clean energy entrepreneurship improve energy access and women empowerment in Sub-Saharan Africa?
Authors: Fajardo Mazorra Adriana Patricia
Published: September 2022

Alleviating energy poverty in Sub-Saharan Africa requires innovative and decentralized solutions to provide energy access. To reach the most isolated markets, off-grid energy enterprises have adopted business models which integrate local entrepreneurs, many of which highlight women’s engagement. Literature and opinions on gender approaches to promote clean energy entrepreneurship are divided between those who advocate for women’s capacity to advance energy security and others who support energy entrepreneurship as an enabler for women’s empowerment. However, we should look first at both outcomes and ask: can gender approaches to promote clean energy entrepreneurship improve energy access and women empowerment? This dissertation aims to answer this question through the evidence from two off-grid energy businesses, Solar Sister and Nuru Energy. It becomes apparent that gender approaches to promote energy entrepreneurship can and do make vital contributions towards improving energy access while promoting women’s economic productivity and social wellbeing. However, evidence points out that gender approaches rely on context, objectives, and capacity to bring the structural transformations that energy security and true empowerment require.
Differential expression of FAM60A in amyotrophic lateral sclerosis.
Authors: Mamoor Shahan
Published: September 2022

Neurodegenerative diseases that affect the motor neurons, including amyotrophic lateral sclerosis (ALS), have little treatment options and are generally rapidly fatal (1, 2). We harnessed the power of unbiased, whole transcriptome differential gene expression analysis, utilizing primary patient cells and tissues to discover genes whose expression defines ALS using published data (3, 4). We found significant differential expression of FAM60A, encoding family with sequence similarity 60 member A, in the primary motor neurons of patients with ALS. FAM60A was also differentially expressed in the skeletal muscle of patients with ALS. FAM60A transcript was present at significantly higher levels in ALS patient motor neurons as compared to control motor neurons. These analyses will begin to define the transcriptional landscape of ALS.

Invasive species have their invasion limits
Authors: Nguyen Minh-Hoang
Published: September 2022

Biodiversity loss is happening at an unprecedented rate, and invasive species are one of the main contributors to the global biodiversity decline. Invasive species are alien (non-native) organisms that become overpopulated and cause environmental harm to the native environment. For example, a recent global meta-analysis shows that 30 invasive predator species have been linked to the extinction or endangerment of 738 vertebrate species, accounting for 58% of all bird, mammal, and reptile extinctions.For effective biology conservation, some questions are worth answering:Do invasive species have any invasion limits? Or are they capable of invading habitats significantly different from their native environment due to their strong adaptability?

Psychological Assessments in Forensic Settings
Authors: Neal Tess M.S. , Mathers Elizabeth , Frizzell Jason
Published: September 2022

Psychologists are often asked to help judges, jurors, and other parties make decisions in legal cases when there are questions about a person’s psychological capacities, current or past psychological functioning, or/or future behavioral likelihood. This chapter focuses on these types of cases, introducing a subfield of psychology called forensic psychology, which involves the application of psychological science or professional practice to the law to inform pending legal decisions (APA, 2013; Neal, 2018). We introduce the basics of psychological assessments; address scenarios when the legal system may be interested in psychological assessment, including the most common forensic referral questions; and discuss ethics, including the unique features and dilemmas of working in legal contexts, such as the need to understand and address the problem of multiple roles and striving to reduce bias and error in our work. We cover typical processes involved in forensic assessment, from referral, to assessment processes, to report writing, to testifying. We conclude with limitations of psychological assessments in legal settings and future directions for research and practice.
Numerical Approximation of the First-Passage Time Distribution of Time-Varying Diffusion Decision Models: A Mesh-Free Approach
Authors: Hadian Rasanan Amir Hosein , Evans Nathan J. , Rieskamp Jörg , Rad Jamal Amani
Published: September 2022

Sequential sampling theory is the dominant theoretical framework for explaining human decision making behavior. In this theory, the decision process is determined by a stochastic process in a bounded domain, with the likelihood function of the model being the first passage-time distribution of this process. However, many sequential sampling models have no analytic formulation for the first passage-time distribution, making these models difficult and computationally taxing to fit. Thus, developing an efficient and general approximation procedure for the first-passage time distribution of sequential sampling models is crucial for the field of mathematical psychology. Here, we have developed a numerical algorithm based on the mesh-free techniques for numerically solving the Fokker-Planck differential equation, which allows us to approximate the first passage-time distribution of some important classes of sequential sampling models, including the urgency signal model, Ornstein-Uhlenbeck model, and collapsing threshold model. Since the considered equation is a singular partial differential equation in a moving boundary domain, the proposed numerical method first transforms the equation to a regular domain, and then the solution is approximated based on the collocation method. However, since satisfying the boundary conditions in the collocation algorithms can be very tricky, we have imposed the boundary conditions in the basis functions. The performance of the proposed method is illustrated by solving several examples.
Conscious cognitive effort in cognitive control
Authors: Shepherd Joshua
Published: September 2022

Cognitive effort is thought to be familiar in everyday life, ubiquitous across multiple variations of task and circumstance, and integral to cost/benefit computations that are themselves central to the proper functioning of cognitive control. In particular, cognitive effort is thought to be closely related to the assessment of cognitive control’s costs. I argue here that the construct of cognitive effort, as it is deployed in cognitive psychology and neuroscience, is problematically unclear. The result is that talk of cognitive effort may paper over significant disagreement regarding the nature of cognitive effort, and its key functions for cognitive control. I highlight key points of disagreement, and several open questions regarding what causes cognitive effort, what cognitive effort represents, cognitive effort’s relationship to action, and cognitive effort’s relationship to consciousness. I also suggest that pluralism about cognitive effort – that cognitive effort may manifest as a range of intentional or non-intentional actions the function of which is to promote greater success at paradigmatic cognitive control tasks – may be a fruitful and irenic way to conceive of cognitive effort. Finally, I suggest that recent trends in work on cognitive control suggests that we might fruitfully conceive of cognitive effort as one key node in a complex network of mental value, and that studying this complex network may illuminate the nature of cognitive control, and the role of consciousness in cognitive control’s proper functioning.
Cortical haemodynamic responses predict individual ability to recognise vocal emotions with uninformative pitch cues but do not distinguish different emotions
Authors: Moffat Ryssa , Başkent Deniz , Luke Robert , McAlpine David , Van Yper Lindsey
Published: September 2022

We investigated the cortical representation of emotional prosody in normal-hearing listeners using functional near-infrared spectroscopy and behavourial assessments. Consistent with previous reports, listeners relied most heavily on F0 cues when recognizing emotion cues; performance was relatively poor—and highly variable between listeners—when only intensity and speech-rate cues were available. Using functional near-infrared spectroscopy (fNIRS) to image cortical activity to speech utterances containing natural and reduced prosodic cues, we found right superior temporal gyrus (STG) to be most sensitive to emotional prosody, but no emotion-specific cortical activations, suggesting that whilst fNIRS might be suited to investigating cortical mechanisms supporting speech processing it is less suited to investigating cortical haemodynamic responses to individual vocal emotions. Manipulating emotional speech to render F0 cues less informative, we found the amplitude of the haemodynamic response in right STG to be significantly correlated with listeners’ abilities to recognise vocal emotions with uninformative F0 cues. Specifically, listeners more able to assign emotions to speech with degraded F0 cues showed lower haemodynamic responses to these degraded signals. This suggests a potential objective measure of behavioural sensitivity to vocal emotions that might benefit neurodiverse populations less sensitive to emotional prosody or hearing-impaired listeners, many of whom rely on listening technologies such as hearing aids and cochlear implants—neither of which restore, and often further degrade, the F0 cues essential to parsing emotional prosody conveyed in speech.
Effect of Additives on the Solubility and Dissolution of Piroxicam From Prepared Hard Gelatin Capsule
Authors: B. H. Al-Khedairy Eman
Published: September 2022

Piroxicam is a non-steroidal anti-inflammatory drug (NSAID) used in the treatment of musculo-skeletal and joint disorders. The problem with this drug is its poor solubility in water and hence poor bioavailability after oral administration. In order to improve its solubility and dissolution behavior, hydrophilic additives such as starch, lactose, superdisintegrants including crospovidone (C.P), cross carmellose sodium (CCS), and sodium starch glycolate (SSG) were physically dry mixed with the drug by simple trituration. The improvement in the solubility in 0.1 N HCl was obtained as the amount of starch or lactose increased in the physical mixture, while for superdisintegrants, they further improve the solubility when they are present in small amount and the best improvement was gained with SSG. To study the effect of these additives on the dissolution of the drug, piroxicam capsules were prepared by simple trituration of the drug with starch or lactose or combination of lactose: starch (2:1)by weight with or with out the presence of SSG. The dissolution profiles of these preparations were analyzed using similarity factor f2. Best results were obtained when the drug was triturated with starch and SSG or with acombinaton of  lactose: starch (2:1) by weight with SSG . The dissolution profiles of these preparations were similar to that of the marketed Feldene Â® Pfizer 20 mg capsules with f2 74.6 and 80.37 respectively.

Published: September 2022

Human resistin is an adipokine, with a possible link to coronary heart disease.A few studies were done about resistin in acute phase of ST-segment elevation myocardial infarction (STEMI) especially in Iraqi patients. Accordingly we design a study to investigate the association between resistin concentration and acute phase of STEMI in Iraqi patients.

The present study was carried out at Al-Yarmouk Teaching Hospital from December 2011 until June 2012. Serum resistin levels were measured in 50 patients with acute STEMI (mean age: 58.16 Â± 11.73 years) at the first 12 hours of admission and 34 normal controls (mean age: 53.98 Â± 15.46 years) matched for age, sex and other risk factors.

 Resistin level in patients with acute STEMI (13.08 ng/mL) was significantly higher than that of the control group (5.31 ng/mL) (p < 0.0001). The study revealed a significant negative correlation between serum resistin level and serum adiponectin level among patients.

Authors: J. Ibraheem Al-Tamimi Jaafar
Published: September 2022

The bioequivalence of a single dose tablet containing 5 mg amlodipine as a test product in comparison to NorvascÂ® 5 mg tablet (Pfizer USA) as the reference product was studied. Both products were administered to twenty eight healthy male adult subjects applying  a fasting, single-dose, two-treatment, two-period, two-sequence, randomized crossover design with two weeks washout period between dosing. Twenty blood samples were withdrawn from each subject over 144 hours period. Amlodipine concentrations were determined in plasma by a validated HPLC-MS/MS method. From the plasma concentration-time data of each individual, the pharmacokinetic parameters; Cmax, Tmax, AUC0-t, AUC0-Â¥, Cmax/AUC0-Â¥, lZ, T0.5, MRT, Cl/F and Vd/F; were calculated applying non-compartmental analysis. The average values of the above parameters  for the test formula were 1.99 ng/ml, 8.3 hours, 82.87 ng.hr/ml, 95.23 ng.hr/ml, 0.0219 hr-1, 0.018 hr-1, 38.5 hr, 56.2 hr, 60.9 l/hr and 3483 liters, respectively. The average values of these parameter for the reference formula were 1.92 ng/ml, 7.9 hours, 76.3 ng.hr/ml, 89.31 ng.hr/ml, 0.0225hr-1, 0.019  hr-1, 36.7 hr, 59.9 hr, 69.5 l/hr, and 3983.4 liters, respectively. The pharmacokinetic parameters mentioned above were statistically analyzed by ANOVA test. Ln-transformed values of the pharmacokinetic parameters used for bioequivalence testing; Cmax, AUC0-t and AUC0-Â¥ ; were also statistically analyzed by ANOVA, 90% Confidence Interval (CI) and Schuirmannâ€™s two one-sided t-tests. For the Tmax, parametric and nonparametric tests were applied. Based on FDA criteria on bioequivalence, the results of the above statistical tests demonstrated bioequivalence of the two products.

Authors: A. Ahmed Zheen
Published: September 2022

Kidney damage in workers within environments of highly expected exposure to toxin, including heavy metals, could be a primary marker to expect hazards in population exposed to low levels of many environmental pollutants. The present study was designed to evaluate the possible effect of environmental exposure to cadmium and zinc on renal function among painters in Sulaimani city. Cross sectional study was performed on 37 male painting workers in Sulaimani city. Each worker was interviewed using structured questionnaire. Twenty five non-exposed healthy subjects were included as control group. Venous blood samples (10 ml) were obtained by vein puncture from both subjects and utilized for estimation of serum urea, creatinine levels, serum levels of cadmium (Cd) and zinc (Zn), and for the estimation of malondialdehyde. The results show that serum urea levels were significantly elevated in painters; meanwhile, no significant difference was reported in serum creatinine levels. The results indicated that both serum levels of (Cd) and (Zn) were not significantly elevated in painting workers; however, MDA levels were significantly elevated in painters compared to control group. In conclusion, the association of cadmium and zinc levels with the disturbance in renal function is not clear in painters working in Sulaimani city.Keywords: Painting workers, Cadmium, Zinc, renal function, oxidative stress

After two-years of talking to around 170 early career science/social science researchers from China, France, Malaysia, Poland, Russia, Spain, UK and US about their work life and scholarly communications during the pandemic, the Harbingers-2 project is in possession of a mountain of verbatim data. The purpose of this paper is to highlight the kinds of comments ECRs are raising, with a focus on those that provide a particular interesting and illuminating take on ECRs’ experiences under difficult times. Comments, for instance, that might challenge the established order of things or that presage big changes down the line. The selection of comments presented here were made by the national interviewers shortly after the completion of the last of three rounds of interviews (two interviews in the case of Russia). The understandings, appreciations and suggestions thus raised by the ECRs are insightful and constructive, which is what we might have expected from this cohort who are very much at the forefront of the research enterprise and veritable research workhorses. Sixteen broad scholarly topics are represented by quotes/comments, with the main focus of the comments on a subset of these: research performance and assessment, scholarly communication transformations, networking and collaboration, social media and access to information/libraries, which suggests, perhaps, where the action, concerns and interest mainly lie.

Published: September 2022

This paper describes in detail the solid-phase sintering mechanism of BeO ++ ceramics in the 1520–1550 °C temperature range. It is shown that the structural elements are formed due to the processes of pore disappearance and grain growth in the process of ceramic shrinkage during sintering. It is found that under the influence of TiO2 nanoparticles it is possible to increase the sintering temperature of such ceramics by 30 °C, which promotes the transformation of the crystal structure of TiO2 into a more conductive Ti3O5 with an orthorhombic structure. The mechanism of the slowing down of the grain boundary movement by the second phase impurity as the segregation of nano impurities on the grain boundary is described. The calculation of binding energy of spontaneous chemical reactions during sintering of ceramics is performed, chemical elements and compounds related to conductive phase in ceramics of BeO ++ composition atsintering temperature 1550 °С are determined. It is shown that the specific conductivity of the synthesized nanocomposite material increases in comparison with the ceramics consisting of micropowders in the frequency range of 100 Hz–100 MHz, at a sintering temperature of 1550 °С.

Com o presente trabalho, objetivou-se realizar uma revisão de literatura sobre os principais aspectos relacionados à doença de Haff. Enfermidades decorrentes do consumo de carne de peixe podem ser causadas por substâncias tóxicas, por toxinas produzidas pelo próprio peixe, ou microrganismos contidos em água contaminada em que os peixes se reproduzem, provenientes de áreas degradadas, e resíduos e locais de despejo de lixo. Dentre essas diversas patologias, destaca-se a doença de Haff ou doença da urina preta, que é causada por uma toxina que pode ser encontrada em determinados pescados de água doce e representando uma preocupação à saúde humana. A etiologia da doença de Haff, ainda não este bem definida. A doença de Haff apresenta como, principal característica, o desenvolvimento de uma condição grave chamada de rabdomiólise, a qual se trata de uma síndrome provocada por lesão muscular, consequente aumento dos níveis séricos de creatina fosfoquinase (CPK) e escurecimento da coloração da urina, o que caracteriza e comumente nomeia a doença. De modo geral, quando o paciente recebe o tratamento em tempo hábil, o prognóstico da doença de Haff na maioria dos casos é bom, com a maior parte dos sintomas desaparecendo em 72 horas. Considerando os vários riscos à saúde, relacionados ao consumo de peixe cru ou mal cozido, desde problemas gastrointestinais até reações alérgicas e morte, é fundamental que boas práticas de pesca, manejo, conservação e cozimento do pescado sejam adotadas. Além disso, maiores estudos para melhor entendimento desta síndrome de importância na Saúde Pública são necessários.

Role of SHGs in India in Confronting the Pandemic
Authors: Mukherjee Soumita
Published: September 2022

The entire economy is undergoing a stage of acute crisis known as COVID-19. This infectious virus has imposed a serious threat on the survival of human being across the world. This global pandemic has huge impact on the world economy. Like many countries, India is also affected by this. The economy has been badly affected by the pandemic. Several policy measures have been announced by Government, for various sectors to recover from the crisis and regain growth. This paper is an attempt to throw light on the role of SHGs as a warrior against the ongoing pandemic. SHG members in the states of Chhattisgarh, Odisha, Coimbatore, West Bengal and others are actively participating in making masks and sanitizer – the two indispensable things for self-protection to fight COVID-19. Besides this, SHG members are also running community kitchens and handling the spread of misinformation. More than 3 crore masks and 1.2 lakh litres of sanitizers have been produced by SHGs across different states of India, during this period. The government, as a part of stimulus packages, has announced a financial package of Rs. 1.7 lakh crore for poor and vulnerable migrant labours, farmers, and construction workers to help them regain their livelihoods. In this package, the amount of collateral-free loans has been doubled to Rs. 20 lakh from Rs. 10 lakh for SHG members. The role of SHGs in combating the crisis is praiseworthy. The measures taken to come out of the ongoing crisis are expected to benefit many SHGs and in turn million households.
India’s Performance in the Achievement of SDG – 8: An Inquest with Special Reference to Employment Generation and Labour Force Participation
Authors: Paul Biswajit
Published: September 2022

In the last five years, since the adoption of the SDGs, India has been trying to improve in all aspects according to the set targets. Significant progress has already been made in India in recent years. India has taken several SDG initiatives in recent times. Most of the initiatives of the Government of India (GoI) are aligned with the SDG framework to steer development activities. At present, we have 17 UN Sustainable Development Goals (SDGs), and the specific targets for each goal are there. SDG – 8 for economic growth and decent work is one of them. The research question is how far India has achieved the targets of SDG–8 because this goal is directly related to economic growth. In this context, the paper attempts to analyse the performance of India in the achievement of SDG–8, presenting the trends of employment generation and labour force participation rate. These two indicators are analysed in this study with the help of the International Labour Organisation (ILO) database. It is possible to conclude from this analysis that the improvement in India's employment rate and labour force participation rate over the last decade has been insufficient.
Healthcare System of India and the Covid-19 Pandemic: A Study on the Challenges and Road Map Ahead
Authors: Naskar Debasish , Biswas Bappaditya
Published: September 2022

The world is currently experiencing the Covid-19 pandemic in more than 200 countries and territories all over the globe. India is one of the worst-hit countries by this pandemic. The healthcare sector is one of the worst affected by this pandemic. The lack of protective equipment, including N95 face masks, sanitizers and poor sanitizing process, poor medical facilities, shortage of ICU beds and ventilators, and excessive healthcare costs have made the situation more dangerous and revealed the weakness in our healthcare system. Low investment in the public healthcare sector creates a challenge for India's COVID-19 containment strategy. A huge variation in the healthcare system can also be found across the different states in India. These variations create challenges for the country's disease containment strategy. Though a well-structured health care system and well-established infrastructure are needed to counter this pandemic, India is far behind compared to the other developed and developing countries. However, new opportunities have evolved for India to develop newer drugs and vaccines to stand against this pandemic.
