The first question that comes to the mind of students who have completed their undergraduate studies is a very confusing thought. Do I need to do my Postgraduate or take a Job and gain some experience? Do I need a post-graduate degree to improve my full-stack development or other Programmeming careers? Well, an answer to this question would be a NO. As far as database and full stack development are concerned it is only a skill. With basic education and good practice, you can always enhance your skills and pursue the relevant job, but there are many pros to having a master’s degree in computer science and software engineering which I would like to highlight in this article. If you have enjoyed and learnt basic skills at Under Graduate level it will continue to improve your learning at a higher level. An Undergraduate course will focus only on the fundamentals of the course. Whereas a master’s degree will guide you into more specialized paths. As far as computer science and software engineering are concerned I would like to highlight the top ten courses in Master’s [1]. MSc Web Design and Development Master in Big Data Solutions Master’s Degree in Research in Cybersecurity Master in Computer Science Software Engineering for Embedded Systems Master’s Degree in Business Intelligence and Big Data in Cyber Secure Environments Digital Humanities Computer Science Online MSc Master in Computer Science & IT Security Master of Science in Data Science and Artificial Intelligence Having a Master’s Degree will immediately elevate your technical status at your current or prospective company. In case of debates of promotion internally in a workplace, your master’s degree will be the key to justifications. It is also important to note that sometimes the place where you work, will be ready to pay your tuition reimbursement to pursue your Master’s. In that case, all you need is some time to avail your resource. This scenario highlights how companies value your Master’s degree as advanced when it is ready to pay for it. In the case of having ideas to pursue doctorate degrees the master’s degrees will take you one step closer to the goal. In case you have an idea to teach at a University, a master’s degree will help you to attain your goal. Most universities hire faculty with the minimum master’s degree for this position. A master’s degree with relevant experience will take you high in these postings. Conclusively, a full stack or Programmeming job doesn’t require a master’s degree, but in case you pursue it, it will be considered. A master’s degree will always open doors to an enhanced future than the UG degree. You will find versatile opportunities and be self-motivated when you have higher qualification Reference [1] https://www.educations.com/top-10-lists/top-10-popular-online-masters-computer-science-information-technology-18431 [2] https://cacm.acm.org/blogs/blog-cacm/224837-benefits-of-a-masters-degree-in-computer-science/   Dr.Vijay Arputharaj is a lecturer at Skyline University Nigeria and has completed his PhD in Computer Science from Bharathiar University, Coimbatore, India.

Global warming is an issue that affects the entire world. It is one of the most pressing environmental problems facing humanity today, and its effects are felt in all parts of the globe. Global Warming can simply be understood as an increase in the average temperature of the earth. The term is used to describe climate change that is attributed to human activities. It was first used by Wallace Broecker, who published an influential paper titled “Climatic Change: Are We on the Brink of a Pronounced Global Warming?” in 1975. The current scientific consensus on climate change is that it is caused by human activities, such as burning fossil fuels and deforestation, which release greenhouse gases such as carbon dioxide into Earth’s atmosphere. The Intergovernmental Panel on Climate Change (IPCC) summarizes current scientific thinking with their best estimate of future climate change and its impacts. In 2007 they concluded that most of the observed warming since 1950 is likely due to anthropogenic causes. Many governments have signed agreements committing themselves to reductions in emissions, primarily through limitations on carbon dioxide emissions or increases in efficiency; there are also many non-government actions being taken as well. These agreements are generally considered insufficient to prevent significant global warming. Human activities that cause global warming include burning fossil fuels, such as coal and oil; clearing land for agriculture, forestry, and development; and driving vehicles. Burning fossil fuels releases greenhouse gases into the atmosphere, which trap heat from the sun’s rays inside the Earth’s atmosphere causing Earth’s average temperature to rise. Clearing land also releases greenhouse gases into the atmosphere and reduces the number of trees available to remove carbon dioxide from the air. Driving vehicles emit pollutants that contribute to global warming. Reducing your reliance on fossil fuels, driving less, and supporting reforestation are all ways you can help reduce global warming caused by human activity. Carbon dioxide is emitted when fossil fuels are burned for electricity, transportation, heating and industrial processes. Carbon dioxide is also emitted when we burn trees and other plants as part of deforestation. And carbon dioxide is released into the atmosphere every time someone drives their car or flies on an aeroplane. Many scientists have said that these activities can cause changes to our planet’s climate over time that could disrupt weather patterns and alter ecosystems. We’re already seeing some of those effects today with things like more extreme storms and rising sea levels due to melting ice caps. The federal government has said as of 25th October 2022, at least 603 people have been killed in floods across Nigeria with 1.3 million persons displaced from their communities. Some of the states where deaths from floods have been reported include Kogi, Anambra, Kebbi, Delta, Bayelsa, and Jigawa with about 31 states said to have experienced flooding in 2022. Minister of Humanitarian Affairs, Disaster Management and Social Development, Sadiya Umar Farouq, revealed that about 82,053 houses had been totally decimated, 2,504,095 million persons were affected, and 332,327 hectares of land were completely damaged. Other statistics indicated that the number of injuries is 2,407, while houses that were partially destroyed totals 121,318, and farmland partially decimated is 108,392. Though human activities in Africa are not wholly responsible for global warming, Africans and others in developing nations bear most of the brunt. In effect, deliberate efforts must be made in developing nations to limit the activities that could lead to further environmental degradation. There are a number of steps that individuals in Africa can take to reduce the effects of global warming. Firstly, it is important to increase awareness of the issue and its potential impacts. This can be done through education and outreach Programmemes which target both adults and children. Secondly, energy efficiency measures should be adopted in order to reduce emissions from power generation and use. This includes using energy-efficient appliances, insulating homes and office buildings, and promoting the use of renewable energy sources such as solar power. Thirdly, individuals must desist from activities related to deforestation like cutting down trees without replacement. Again, water conservation efforts must be undertaken in order to reduce the amount of water used for irrigation and other purposes. This includes installing low-flow showerheads and toilets, using greywater systems, and planting drought-resistant vegetation. By taking these simple steps, Africans can make a significant contribution towards mitigating the effects of climate change. Reference Broecker, W. S. (1975).

With the advent of Nigeria’s Fourth republic in 1999, stakeholders reflected deeper on what should be the main focus of the country’s foreign policy. Thus, with the emergence of Alhaji Umaru Musa Yar’Adua as Nigeria’s president in 2007, further reflection was made on what should constitute the Nigerian foreign policy focus. In light of this, the then Minister of Foreign Affairs, Ojo Maduekwe, was prepared to make a difference with the initiation of the principle of Citizen Diplomacy. This principle, in accordance with the constitutional directive principles, placed priority on the protection of the interest of Nigerian citizens both at home and abroad. This implies that, the protection of the rights, dignity and privileges of Nigerian citizens will be accorded priority wherever they are and whatever they may be. This shall remain the primary responsibility of Nigeria’s diplomacy. Citizen diplomacy as the new thrust of Nigerian foreign policy is meant to focus on the basic needs, human rights and socio-economic welfare of Nigerian citizens in conducting bilateral and multilateral engagements with other countries. Citizen diplomacy entails the creation of an environment in which every citizen both at home and abroad sees himself as the symbol of his country’s foreign policy; he is expected to work towards strengthening it rather than weakening it. Citizen Diplomacy is being practised by different countries of the world with different magnitudes. Citizen diplomacy in the United States is different from that of China or of Nigeria, while that of Nigeria is different from that of Germany or Moldova. Citizen diplomacy wherever it exists is intended to support the official efforts of the government, as well as promote citizens’ well-being in general. The whole essence of a country’s foreign policy is expected to be tailored towards the benefit of that country and its citizens. Importance The importance of citizen diplomacy in international relations cannot be underestimated. This is because the adequate recognition and care displayed by different countries over their citizens will no doubt boost the morale of the citizens and ginger their interests in assisting their various countries in accomplishing their foreign policy agenda, including making peace. It has equally reawakened the cautiousness of Nigerian citizens. More Nigerians now perceived themselves as responsible citizens and standard bearers of the country that will promote the country’s value wherever they found themselves rather than jeopardize it. The media has equally played a prominent role in this by supplementing citizens’ efforts and communicating their values to policy actors. Prospects Prospectively, citizen diplomacy as a policy thrust of the Nigerian government is a logical continuation of what the country’s foreign policy ought to be and is targeted at obtaining gains from the protection of the citizen’s interest. This has no doubt encapsulated great challenges as has been previously stated. With renewed political will on the part of Nigerian leaders, it is hopeful that foreign policy goals and national aspirations could be met. Placing the citizens at the centre of the national Programmemes reinforces the original purpose of the government and when those in power offer necessary leadership, they will without much effort secure the trust of the general populace and establish centres of national solidarity and more agents of national progress. With that, citizen diplomacy stands a higher chance of yielding the pictured dividends and consequently makes Nigerian Foreign Policy to be robust in terms of implementation and accomplishment. Another prospect of Citizen Diplomacy is that it is capable of re-charting Nigerian Foreign Policy pursuit towards beneficial economic and political engagements that will enhance national development and citizens’ welfare. A situation that is capable of enhancing national unity and integration in a multi-ethnic society like Nigeria. Recommendations Nigerian missions abroad must take these responsibilities as their personal goals. Operational directives must be issued to them, it will be very important that resources are made available for this purpose also. Additionally, there should be improved monitoring directed at the mission’s activities to ensure that identified objectives are accomplished. In conclusion, the introduction of citizen diplomacy in Nigeria is desirable, and timely and must be pursued to the summit, it is a policy that is dynamic, proactive, full of potential and could achieve numerous feats. Nigerian foreign policy should be urgently reviewed and re-packaged in line with new realities of the globalized world in order to make it more efficient, responsive, dynamic and full of punch as regards citizen diplomacy. More outlets that will complement the Nigerian Institute of International Affairs, NIIA, should be established to enable Nigerians to ventilate their opinions and offer inputs that could better the dissemination of foreign policy goals.  Finally, we are of the opinion that the future success of citizen diplomacy requires that, Nigerian foreign policy must be tailored towards result-oriented and directed at aggressively pursuing her interest in Africa and around the world. The era of “Big Brother” in Africa and “free food basket” for other African countries should be reconsidered in view of the new economic realities at home, particularly in a post-oil wealth era to make Nigerian citizens more efficient, responsive, inclusive and proactive based on citizen diplomacy.

An emerging technical field called artificial intelligence (AI) investigates, develops, and applies the theory, approach, method, and system for replicating, enhancing, and expanding human intellect. The “father of artificial intelligence,” physicist Alan Turing, initially proposed the idea in 1950; he created the “Turing test” and claimed that AI was more sophisticated than the human brain but similar to it (Mintz and Brodie, 2019; Kaul et al., 2020). Deep learning, a new generation of AI technology has evolved in recent years. This subset of computer algorithms can automatically gain knowledge from and then artificially and independently conclude the data. Various neural networks, including the deep belief network, convolutional neural network, long- and short-term memory network, etc., are included in deep learning (Kulikowski, 2019). According to AI research, the output-input ratio in medicine is more promising than it is in other industries (Mintz and Brodie, 2019). The marriage of artificial intelligence with medicine transforms the conventional medical model and creates a breakthrough advancement.  Medical diagnosis with AI The time needed to make a diagnosis and the diagnostic effectiveness can both be dramatically increased when a doctor uses AI to diagnose a patient with a specific sickness or condition. By examining clinical radiology data like X-rays, CT scans, MRIs, pathology, and exams using ultrasonography, endoscopy, and biochemistry for relevant bodily indications in humans, the technology can replace the inefficient conventional medical model, to provide conclusions that are prompt and reliable, especially for complex diagnoses. Because AI can resolve problems so quickly, doctors may create a more intentional and acceptable treatment plan depending on the patient’s situation. Use of AI in Medical Treatment In surgery: AI in surgical procedures has gained traction as AI technology advances. PUMA560, Probot, AESOP, Robodoc, and Acrobat were helpful surgical assistants in the modern period. With sharper vision, more practical and precise operation, even remote operation, and other benefits, these technologies represent a tremendous invention unmatched in human history and reduce the amount of surgical intervention. Through this innovative technology, formerly challenging minimally invasive techniques can now be used to undertake complex surgical operations (Stefano, 2017). Perioperative period: This is the time frame surrounding the full procedure, from the time the patient is receiving surgical care until recovery. It is divided into three sections: the preoperative phase, the surgical period, and the postoperative recovery period. Numerous successes with the use of AI technologies have been made across the entire perioperative period. These applications are observed in anesthesiology assistance, three-dimensional printing (3DP) and rehabilitation assistance (Peng-ran et al., 2021). AI in Drug Production Due to the lengthy process involved in producing drugs according to the conventional model—which includes clinical trials, testing, and promotion, drug ingredient design studies, functional target studies, and performance tests—new medications may not always perform as well as anticipated even after extensive research. But as AI has advanced recently, it has altered the healthcare sector’s traditional drug industry and made it easier to find and assemble new drugs (Bajorath et al., 2020; Brown et al., 2020). The novelty and quality of medicines from the AI generation have also reached new heights as they have continuously evolved. Clinical trial procedures have been accelerated, and the time and expense of research and development have dropped owing to predictive AI algorithms with vaccine formulation (Russo et al., 2020; Zhavoronkov, 2020). Conclusion Scientists are already using AI to develop pharmaceuticals, customize therapies, and even modify genes more effectively. But this is only the start. We can utilize AI to assist us to identify important patterns that we can use to make precise, economical decisions in complex analytical procedures the more we digitize and combine our medical data.

Introduction Every person’s preference for future consumption over present consumption, their expectations for future income, and to some extent the interest rate, all have an impact on how much they save. The amount of money it safeguards directly relates to the financial progress. Savings are responsible for boosting of economy in the country. People may invest their savings and build wealth through options such as fixed deposit, mutual funds, stocks, bonds, properties and gold and silver. Diversification of investment help the savings to grow and may lead to greater the amount of capital available for investment. Money does not have any increment unless if it is invested in some proposals. Investment decision differ from one investor to other depending upon their risk bearing based on long term or short term. Gold is the most valuable asset in the economy. Gold may be baptized a hedge against inflation or reservoir for future use or substitute for the currency notes which are used as a means of transfer or exchange. Gold to the investors in recent years has been important mainly because of rise in prices due to inflation. It has been used more for speculation rather than for a long-term investment and for quick profits. Gold is popularly known as ‘yellow metal’ can be invested into either in the form of Gold jewelry, Gold bars, Gold coins, Gold ETF (exchange-traded fund), GSB (Gold Sovereign bonds) and GDS (Gold Deposit Schemes). Applicable Factors to be considered on Gold Investment Options available in gold investment Gold bullion market activities Exchange value Demand and Supply of gold Higher risk protection other than investment options Future security E-Gold Reliability of schemes Actions of (ETF) electronic-traded funds International factors on Gold The worldwide spot price of gold is a factor in determining the metal value of gold because the majority of the gold in any nation is imported. The London bullion market is where the spot price is set. The price of gold will increase if the spot price does, for some reason. Additionally, other global circumstances, such as war and peace, which influence the movement of gold prices globally also have an impact on domestic gold prices. Demand and Supply decides the price of Gold Demand and supply principles direct the pricing of all goods in an economy and gold is no exception. The price of gold will increase, it affect the demand too. This behavior of investors can be seen during holidays, wedding season, or following a successful good monsoons that benefits the rural population. The amount of government reserves in the country has an impact on the gold supply. The price of gold will grow if demand remains constant and the Central Bank sometimes purchases additional gold since it is accepted as an equal to foreign commercial money for the issuing of new currency notes. Adjusting risk in Investment portfolio When other securities markets crash, diversifying an investing portfolio also helps when we include gold as investment option. In challenging market circumstances, gold is crucial for recovering losses. An investor can modify the risk-to-return ratio in their investment portfolio with the use of gold investments. As a result, investing in gold is a wise choice, but there are certain considerations to make before. The main benefit of investing in a liquid asset like gold is its price stability. Compared to other assets, it is simpler to convert into cash. Reselling is therefore a crucial component for which appropriate measures should be made to guarantee that the investment realizes the highest resale value when necessary. Conclusion Gold investments are known to protect against inflation and economic uncertainty. Gold is one of the alternative investment strategies that plays a significant role in an investor’s portfolio. In fact, gold investors now believe that investing in gold has a significant impact on economic growth. In the decision to invest in gold, sentiment is the influenced factor, while safety is the heavily influenced factor. Gold investors place safety first, followed by risk management, mortgage instruments, liquidity, trustworthiness, assured return, market dynamics, and sentiments, as their lowest priorities.

Many people who had a past history of COVID-19 infection are now presenting with cognitive problems with attention, concentration, and memory loss [1]. The doctors are now referring to these problems as COVID-associated ‘Brain Fog.’ Though Brain fog is not a medical or scientific term; it is used by individuals to describe how they feel when their thinking becomes sluggish. The fogginess of the brain is a frequently reported symptom these days, and can be best described as: Cloudy thinking Inability to concentrate the way that one earlier could Lapses in memory Losing train of thought such as forgetting in mid-sentence what you were planning to say, or asking the other person “what was I saying?” frequently Getting distracted easily, with the feeling that the mind is refusing to focus Poor motivation, sluggishness, fuzziness Remember the sickly feeling that we all experience when we are recovering from flu or any illness, jet-lagged or on an anti-allergic medication that makes us fuzzy for a few hours. I am sure that we all have experienced this feeling at some point of time in our life. However, never do these symptoms become so aggravated to get noticed on a daily basis affecting the quality of life and work. Most of the time the sickly feeling disappears once we recover from illness or get adjusted to the new time zone or the side effects of the medication just wear off [2]. However, if this uneasy feeling persists for a long time and disturbs the daily routine then one may be possibly suffering from ‘Brain Fog.’ Reporting of Brain Fog has gone up significantly since the COVID pandemic. It is included as one of the features of long COVID or Post-COVID Syndrome. ‘Chemo brain’ or ‘Chemo Fog’ is a condition in which a cancer patient experiences sluggishness, fuzziness, and a low feeling after receiving chemotherapy. This is because of the inflammation of neurons due to chemotherapy. It is now known that the COVID virus may cause inflammation or swelling of several organs and tissues. The main brunt has been on the lungs but the involvement of other organs was also there that included the brain [3]. Many COVID patients complained of loss of smell as one of their symptoms. This indicates that there may be mild brain inflammation produced by the COVID infection, which may be the cause of ‘Brain Fog.’ According to medical experts, the best way to deal with the problem of ‘Brain Fog’ is to perform an aerobic exercise like walking. While there is no established ‘dose’ of exercise to improve brain health, it’s generally recommended that one can walk 30 minutes a day, five days a week. Maintain a healthy diet that includes fruits, vegetables, nuts and beans, and whole grains. And completely abstain from alcohol and drugs. A normal sleep routine of 7-8 hours every day. The body can heal itself when we sleep at night. Sleep deprivation is one of the main reasons for many mental illness.   Brain Fog may however also happen in people who have not had COVID infection. If the symptoms persist then one should consult a doctor and investigate the blood glucose level, blood pressure, hemoglobin, vitamin B12, and vitamin D levels. One should also look out for hormonal changes, especially irregular periods or thyroid dysfunction. Fogginess of the brain can also be an early symptom of dementia. It is believed that COVID-induced ‘Brain Fog’ will improve gradually and most will gain back their brain’s vitality. However, if the symptoms persist then one should consult a qualified medical expert.     References: Choudhuri G. Coping with Brain Fog. November 7, 2022. https://tinyurl.com/y7pwtwm2 Budson A E.
