Health expenditure assumed enormous importance with the outset of coronavirus pandemic. The disparity between public and private health expenditure will often reflect in the health outcome of any nation. Through the research paper titled ‘The dynamics of public and private health expenditure on health outcome in Southeast Asia’ published in the journal Health and Social Care in the Community, Dr Shailender Singh, Associate Professor, Department of Commerce, attempts to argue that public expenditure on health has a substantial impact over private spending across the countries of ASEA.
Abstract of the Research
This study examines the dynamics of public and private health expenditure on health outcomes in Southeast Asia, vis-a-vis two of the Sustainable Development Goals (SDGs). The techniques of fixed effect, random effect, and feasible generalized least square methods are employed to obtain robust estimates. Further, the analysis dives deep into the country-specific impact of public and private health expenditure on health outcomes using the technique of seemingly unrelated regression. Estimates show that, across Southeast Asia, public health expenditure alone contributes to improving life expectancy at birth, lower levels of under-five, and non-communicable disease mortality rates. Unlike public health expenditure, private health expenditure contributes to better health outcomes only in Brunei and Singapore but not across the countries of Southeast Asia.
The paper asserts that, despite the statistical significance of private health spending with respect to the health outcomes, it does not contribute to lower mortality rate (MR) and higher life expectancy at birth. The results strongly support several prior pieces of evidence in the literature regarding health expenditure and health outcomes. The country-specific estimates show that public health spending contributes greatly to lower mortality rate, particularly in Brunei and Singapore. By contrast, private health spending does not contribute to lower levels of U5MR and NCD mortality rate across the countries of ASEA except in Cambodia, Indonesia, and Philippines.
The differences in economic development and the settings of health systems in these countries could be a plausible reason for the inability of private health expenditure to contribute to lower levels of NCD mortality rate in most of these countries. The result implies that more funding to the public health system has the potential to lower U5MR and NCD MR close to the SDGs target across the countries of ASEA. Also, strengthening the health system through providing greater access to preventive services for diabetes, hypertension, respiratory diseases, and cancers at primary care units may help in better diagnosis and management of these chronic conditions in Indonesia, Laos, and Myanmar where NCD MR is relatively high. However, an increase in funding alone may not be sufficient at improving health outcomes. For emerging conditions, diet modification, active physical exercise, little tobacco and alcohol consumption are also imperative.
The research is reported to be the first of its kind that examines the dynamics of public and private health expenditure on health outcomes in line with the SDGs targets. Apart from the traditional indicators commonly used as health outcomes in the literature (life expectancy and U5MR), the study further extends the literature by introducing NCD MR as an additional health outcome which could play a pivotal role in providing empirical evidence to the health policymakers and researchers.
Health plays an important role in promoting human capital and the economic growth of a country. The available stock of human capital in a country determines the rate of growth in its per capita income. A healthy individual contributes more to their economy by allocating more hours to work, earning more disposable income, in turn investing more in human development.
As the individual stock of health tends to diminish over time, there is a need to augment it by making more investment in time, income, and regular medical care. Thus, this research work has a societal benefit for the population of Southeast Asia to identify the threats in the field of health and focus more on their well-being for improving the state of health. Dr Singh conducted this research in collaboration with Dr Nishant Kumar, Amity University, Noida.
In future, he also intends to analyse the impact of socioeconomic and behavioural health determinants on the health system efficiency of the Middle East region, and to predict the key drivers for health care expenditure growth in the Middle East region through Grossman-PLS Modeling Approach.

Mr Mudigonda Himansh, a 3rd-year BTech-CSE student, has presented a research paper in the IEEE International Conference on Innovations in Information Technology-2022 organised by IIIT Kottayam, Kerala India, in Feb-2022. The paper will be published in IEEE Xplore (Scopus indexed). Dr V M Manikandan, Assistant Professor in Computer Science and Engineering at SRM University-AP, is the co-author of the presented paper titled “A Statistical Study and Analysis to Identify the Importance of Open-source Software”.
Open-source software has picked up pace in the past decade with support from multinational conglomerates and huge open-source communities. We hear a lot about the success of many open-source projects, but we fail to understand how many do not make it. In this paper, Mr Himansh and Dr Manikandan understand the dynamics behind open-source software. They start with the need for open-source alternatives. Then look at a few concerns open-source software developers and maintainers face. Next, we would understand the various requirements of open-source software. Later, we would touch upon the different attributes that affect the selection of open-source software and the decisions to make while building general-purpose, open-source software. Then we would analyse the 5-determinants of open-source software success. Finally, we would look at the data collected from 482 data points from 24 countries and then analyse the data by forming graphs and charts.
This research provides the required knowledge to the open-source and non-open source software developers before-during-after development and production of the software or project. “Our future work is focused on the applications and predicting the scalability of large-scale OSS with machine learning,” says Dr Manikandan.

SRM University-AP is indeed proud of its young and intelligent minds who continue to bring honour and glory to the institution from across the globe. Pulkit Jasti and Tankala Yuvaraj, two of our students from the Department of Computer Science Engineering currently pursuing Semester Abroad Programme at the University of California, Berkeley have won first prize in the prestigious SF Hacks conducted by San Francisco State University, USA, and bagged a total of $950 ($600 for 1st Prize, $250 for Best UI/UX Design, and $100 for Best AIML Hack).
The world has always been ruled and sustained by ideas. Innovating and executing the unthinkable are what helped us tide over the unprecedented hardships the pandemic entailed. SF Hacks 2022, San Francisco’s largest collegiate hackathon was conceived to hatch some striking ideas under the tracks: inclusivity, mental health, sustainability, and machine learning to put the latest technologies to use in the fittest way possible to render solutions to the unending maladies of corona and climate change.
Pulkit Jasti and Tankala Yuvaraj have tread out of the way to introduce an AI-based classroom system that monitors the mental-well being of the students. It is an unfortunate fact that our classrooms have often overlooked the emotional and mental well-being of the students. The transition to virtual mode has made the scenario even worse. Researches state that the depression rates in students between ages 10-18 have increased by 72% since the pandemic.
According to Pulkit and Yuvaraj, this incredible innovation monitors various parameters like facial expressions, voice, attentiveness of a student during the class and generates a meta score that gives an overall idea about the mental well-being of the student. Based on this score, the school counsellors will be notified and then the student can have a one on one therapy session with the counsellor. This system can help identify signs of depression at early stages which makes classroom a safe learning environment for students.
They were determined to come up with an effective solution to redefine the conventional classroom setup and make learning a wholesome experience. “After selecting a problem and drafting the base of the project, we were assured that it could create a positive impact for students during these unprecedented times of the Covid-19 outbreak”, they said.
“During the hackathon, we ran into a lot of technical issues and roadblocks but were able to overcome them and submit our final prototype. To be a part of such a huge event where there were around 1000+ participants from over 26 countries was indeed a remarkable learning experience”, they expressed their feeling of contentment. “We can never thank enough our faculty at SRM for their enormous support throughout our journey at the University of California Berkeley” they added.
- Highly efficient catalysts of Ruthenium clusters on Fe3O4/MWCNTs for hydrogen evolution reaction March 22, 2022
“Highly Efficient Catalysts of Ruthenium Clusters on Fe3O4/MWCNTs for Hydrogen Evolution Reaction” is the latest paper published by Prof Ranjit Thapa, Professor of Physics at SRM university-AP and his PhD scholar, Mr Samadhan Kapse, in ‘New Journal of Chemistry’ having an Impact Factor of 3.591.
In this work, the chemical co-precipitation technique is adopted to produce Fe3O4 nanoparticles under an inert atmosphere and was utilized for HER studies. The Ru nanoparticles were profitably deposited over Fe3O4/MWCNTs GC electrode using electrochemical deposition technique. The superior HER activity was achieved on Ru/Fe3O4/MWCNTs in 0.1 M H2SO4 aqueous media. We have demonstrated that the synthesized electrocatalyst offers a low overpotential of 101 mV to achieve a current density of 10 mA cm-2 towards the hydrogen evolution reaction. It displays long-term durability, exceptional cyclic stability even after 1000 cycles. DFT calculations imply that the availability of both octahedral and tetrahedral sites in Ru/Fe3O4/MWCNTs with low overpotential is more efficient towards HER. It is emphasized that a low percentage of ruthenium in the prepared catalyst can be substituted as a promising HER catalyst for sustainable energy technologies.
Abstract of the paper
Producing molecular hydrogen (H2) using water provides a sustainable approach for developing clean energy technologies. Herein, we report highly active ruthenium clusters (Ru) supported on iron oxide (Ru/Fe3O4) and Fe3O4/multi-walled carbon nanotubes (Ru/Fe3O4/MWCNTs) by simple electrochemical deposition in a neutral aqueous medium. The supported catalyst exhibits good hydrogen evolution reaction activity (HER) in an acidic environment. Cyclic voltammograms (CV) in potassium ferrocyanide (K4[Fe(CN)6]) confirm MWCNTs enhance the electron transfer process by decreasing the redox formal potential. The overpotential of Ru/Fe3O4/MWCNTs and Ru/Fe3O4 electrocatalysts versus reversible hydrogen electrode (RHE) was found to be 101 mV and 306 mV to reach a current density of 10 mA cm-2 . As prepared, the catalyst displays good stability and retain its HER activity even after 1000 cycles. Further, the stability of Ru/Fe3O4/MWCNTs was studied using chronopotentiometric (CP) technique for 12 hrs and found negligible loss in the catalytic activity towards HER. To explore the role of Ru and underneath MWCNTs to improve the catalytic performance of Fe3O4, density functional theory (DFT) calculations were carried out. DFT calculations indicate the octahedral site of Ru/Fe3O4 favours HER with low overpotential. However, Ru/Fe3O4/MWCNTs is more efficient towards HER could be due to the availability of both octahedral and tetrahedral catalytic sites.
Social implications of the research
Renewable energy generation is of greater importance in the present circumstances. This is caused by the depletion of non-renewable energy sources like fossil fuels and other hydrocarbon deposits and the release of greenhouse gases into the atmosphere. Hydrogen has gained considerable interest as an energy storage and energy carrier because of its high energy density (146kJ/g). Furthermore, its lightweight, profusion nature and the release of water during its combustion eliminate environmental pollution and thus contribute to defeating the global energy crisis. Also, hydrogen is an important and ideal energy source to develop fuel cells. A number of methods have been explored to generate molecular hydrogen. Among them, water electrolysis is a promising technology for generating high-purity hydrogen from water. An excellent electrocatalyst is obligatory to liberate hydrogen gas effectively from water. A higher HER activity is known to be obtained from platinum (Pt) and Pt-based catalysts. Given its high cost and low surplus, it limits expansion to the industrial scale. Over the few past decades, lots of efforts have been made by many research teams to find out alternative catalysts to substitute Pt electrodes.
The paper is published in collaboration with Shwetha Kolathur Ramachandra, Doddahalli Hanumantharayudu Nagaraju, and Shivanna Marappa; School of Applied Sciences, REVA University, Bangalore-560064, Karnataka, India. According to the research group, the density functional theory can boost the searching process of highly promising electrocatalysts for hydrogen evolution reactions in renewable energy generation.

The Department of Chemistry is glad to announce that Dr J P Raja Pandiyan has published a paper titled ” Microfluidics and surface-enhanced Raman spectroscopy, a win-win combination?” in the journal ‘Lab on a Chip’ having an impact factor of 6.79 in collaboration with researchers from different universities across India, Germany, and Japan.
Abstract of the Research
With the continuous development in nanoscience and nanotechnology, analytical techniques like surface-enhanced Raman spectroscopy (SERS) render structural and chemical information of a variety of analyte molecules in ultra-low concentration. Although this technique is making significant progress in various fields, the reproducibility of SERS measurements and sensitivity towards small molecules are still daunting challenges. In this regard, microfluidic surface-enhanced Raman spectroscopy (MF-SERS) is well on its way to join the toolbox of analytical chemists. This review article explains how MF-SERS is becoming a powerful tool in analytical chemistry. We critically present the developments in SERS substrates for microfluidic devices and how these substrates in microfluidic channels can improve the SERS sensitivity, reproducibility, and detection limit. We then introduce the building materials for microfluidic platforms and their types such as droplet, centrifugal, and digital microfluidics. Finally, we enumerate some challenges and future directions in microfluidic SERS. Overall, this article showcases the potential and versatility of microfluidic SERS in overcoming the inherent issues in the SERS technique and also discusses the advantage of adding SERS to the arsenal of microfluidics.
About the Raman Research Group at SRM AP
Raman spectroscopy, invented by Sir CV Raman in 1928 and got Nobel Prize in 1930, is a vibrational spectroscopic technique that works based on the principle of inelastic scattering of light. Surface-Enhanced Raman spectroscopy (SERS) is one of the modern analytical techniques which can detect chemical and biomolecules in an ultra-low concentration. The research group is working on the development of the SERS technique to address the issues in food, environmental, energy and biological science.
The newly developed SERS substrates are mainly used for the detection of biological samples for disease diagnosis, food samples to ensure food safety, water samples to study the contamination and pollution rate. These studies can make meaningful social changes and improvements.

The Department of Economics is delighted to announce that Dr Ghanshyam Kumar Pandey and his research group; Sheeba Moghal, Rakshit Barodia, and William Carey have published an article titled “COVID-19 and its effects on the mental health of people living in urban slums in India” in the ‘Journal of Information and Knowledge Management’, having an Impact Factor of 1.3.
The study confirms that more than three-fourth of the population suffer from mental stress due to the spread of COVID-19 and the lockdown imposed by the government. Eighty per cent of those surveyed stated that the stress had affected their decision-making. The study also confirms that the number of dependents, monthly income, number of living rooms, maintenance of physical distancing norms, avoidance of social gatherings, government support, health insurance, and living in a rented house are significantly related to the mental stress of people living in slums in Andhra Pradesh in India.
Abstract of the Research
The COVID-19 pandemic has had a devastating effect on the mental health of people from different backgrounds; these effects have been particularly acute among lower-income households and in slums. There has been a steep rise in mental illness and behaviours associated with it since 2020, especially in slums characterized by poverty, poor housing, high density, and unhealthy environments. This paper aims to examine the effect of COVID-19 on the mental health of people living in the slums of Vijayawada and Visakhapatnam in the state of Andhra Pradesh in India.
