* Stop in the Ethiopian region among the longest in the world

* Authorities say closures help reduce violence

By Zecharias Zelalem Sep 29 (Thomson Reuters Foundation) – She had just been crowned world champion, but Ethiopian marathon runner Gotytom Gebreslase broke down in tears when asked if her family were celebrating her victory in war-torn Tigray .

“I haven’t spoken to my parents in months,” she said, wiping her eyes during a press conference at the World Championships in Athletics in Eugene, Wash. Oregon, in the northwestern United States, in July. “I wish my father and mother could celebrate my achievement like other Ethiopians.”

Few have been spared the effects of a nearly two-year-long internet and phone blackout in Ethiopia’s northern Tigray region, which has been cut off since fighting erupted between Tigrayan rebels and government forces in November 2020. Conflict resumed last month after a month-long humanitarian truce, dashing hopes of restoring communications.

Even the head of the World Health Organization (WHO), Tedros Adhanom Ghebreyesus, from Tigray, said he had been unable to reach his relatives or send them money. “I don’t even know who’s dead or who’s alive,” Tedros told a recent press conference in London.

As fighting continues in Tigray and elsewhere in Ethiopia, Prime Minister Abiy Ahmed’s government says shutdowns are needed to curb the violence, but critics accuse authorities of using the internet as a weapon of war. “Access to communications and other basic services, and especially humanitarian aid, is explicitly used as a bargaining chip by the Ethiopian government,” said Goitom Gebreluel, a political analyst specializing in Horn of the East affairs. ‘Africa.

“It is used as leverage against Tigray and the international community.” SATELLITE PHONES AND PRINTS

Around the world, internet shutdowns have become more sophisticated, last longer, harm people and the economy, and target vulnerable groups around the world, according to digital rights group Access Now. It recorded some 182 internet shutdowns in 34 countries last year, compared to 159 shutdowns in 29 countries the previous year.

In Ethiopia, sporadic internet and phone blackouts have been used as “a weapon to control and censor information”, the group said, making it difficult for journalists and activists to document alleged crimes against women. human rights and to deliver aid. In Tigray’s regional capital, Mekelle, emergency workarounds such as satellite phones have become a vital tool for aid agency operations.

The International Committee of the Red Cross (ICRC) also maintains a satellite phone service for local residents, giving them a way to get a message to loved ones. Since the beginning of the year, the ICRC has facilitated some 116,000 phone calls and voice messages “between family members separated by conflict and violence”, spokeswoman Alyona Synenko said.

With nearly half of the region’s six million people in dire need of food, the closure along with roadblocks have hampered the delivery of humanitarian aid, according to the United Nations World Food Programme. The lack of mobile phone networks has also “crippled both emergency and routine health surveillance systems”, a WHO spokesperson said in emailed remarks.

The only way to communicate is “via paper reports which must be hand-delivered. All meetings must be in person.” Government officials accuse the rebels of deliberately damaging telecommunications networks, while representatives of the Tigray People’s Liberation Front (TPLF) say Abiy’s administration is unwilling to restore the services it cut.

A spokesperson for Abiy said there was “not a single on/off button or switch” to restore the internet. “Security and administrative arrangements in the Tigray region need to be clarified…to facilitate technical repair work,” the spokesman told reporters last month.

TPLF adviser Fesseha Tessema disputed this. “The question is political, because Addis Ababa does not want to lift the siege and restore services,” he told the Thomson Reuters Foundation.

‘THEY LEAVE IT TO GOD’ When popular singer and Oromo activist Hachalu Hundessa was killed in June 2020 in a suburb of the capital, Addis Ababa, the government disconnected the internet across the country as riots and killings escalated. have spread to Oromia and Addis Ababa.

A police crackdown left hundreds dead and a 23-day internet blackout cost the economy more than $100 million, according to NetBlocks, an internet monitoring company. Frehiwot Tamiru, chief executive of the sole telecommunications provider – government-owned Ethio Telecom, said the nationwide shutdown was necessary to prevent the internet from being used by criminals to “kill and displace, create chaos and destroy the country”.

Human rights groups have also criticized the Ethiopian government for shutting down social media and messaging services, including Facebook and WhatsApp, over the past year. Ethiopian authorities have not commented on the closures, but said last year they were developing a local social media platform to “replace” Facebook, Twitter and WhatsApp.

Many ordinary Ethiopians lament the frequent disruptions to their daily lives. Like any 15-year-old, Tolessa loved checking football scores online and messaging friends on his phone, until frequent internet blackouts in his hometown of Oromia made that nearly impossible.

As the war between Ethiopian forces and Oromo Liberation Army rebels escalated in 2019 and 2020, residents used their phones when they could to alert themselves to the approaching fighting – until broadband and mobile internet shut down. “Now it’s all just a bet – they’re relying on God,” said Tolessa, who asked to use a pseudonym to protect his identity.

Fearing for his safety, Tolessa’s family sent him to live with relatives in Addis Ababa about 300 km (185 miles) away, where he now goes to school and hopes to become an engineer. It’s a struggle to stay in touch. “I can only reach some relatives by phone, most of them haven’t been online for months,” he said.

In Tigray, Eyassu Gebreanenia, 24, from Mekelle, said he was able to go online once or twice a month, using Wi-Fi at the office of an international non-profit organization where his friend works. The city was once the region’s bustling business hub, but Gebreanenia said hospitals, hotels and restaurants are closed and people who once owned thriving businesses are now struggling to feed their families.

“It’s like they’ve gone back 30 years,” he said. “People are hurting – but you might not know it because we’re cut off from the world. It’s quite depressing.” Originally posted at: https://www.context.news/digital-rights/six-million-people-in-the-dark-tigrays-two-year-internet-outage

MIT takes a step forward in technology to monitor Parkinson’s disease https://isi-epaper.com/mit-takes-a-step-forward-in-technology-to-monitor-parkinsons-disease/ Wed, 21 Sep 2022 18:02:30 +0000 https://isi-epaper.com/mit-takes-a-step-forward-in-technology-to-monitor-parkinsons-disease/ Engineers at the Massachusetts Institute of Technology recently unveiled a radar-like device that could test people for signs of Parkinson’s disease while they sleep.

Engineers at the Massachusetts Institute of Technology recently unveiled a radar-like device that could test people for signs of Parkinson’s disease while they sleep. Now they say the same system can monitor Parkinson’s patients in a different way, by tracking their walk.

“We know very little about the brain and its diseases,” said Dina Katabi, an MIT electrical engineering professor who led the project. “My goal is to develop non-invasive tools that provide new insights into brain function and disease.”

The system developed by Katabi and his colleagues, Yingcheng Liu and Guo Zhang, uses a radio transceiver that can be installed in a person’s home. The device broadcasts a much weaker signal than a typical home Wi-Fi router. The signal can pass through walls but is reflected by water in the human body. The receiver picks up the reflected signal like a radar system and continuously monitors human movements.

Last month, Katabi said the technology could be used to detect changes in a sleeping person’s breathing patterns, an early sign of Parkinson’s disease. His team uses the same hardware, with different software, to track the current status of Parkinson’s disease patients as they walk around the house. Patients with Parkinson’s disease tend to walk more slowly than healthy people of the same age.

According to a paper published Wednesday in Science Translational Medicine, Katabi and his colleagues tested the system for a year on 50 people, including 34 with Parkinson’s disease. The receiver collected 200,000 observations. By analyzing the data, they were able to distinguish between test subjects who had the disease and those who did not.

More importantly, they were able to measure the effectiveness of Levodopa, a drug intended to control the symptoms of the disease. For example, patients’ walking speed reportedly tends to improve for a while after taking the drug and then deteriorate as the effects wear off.

The system would reduce the need for doctor visits, as the doctor could monitor patients at home, in real time. The additional data could also help doctors prescribe the optimal dosage of drugs for Parkinson’s disease. And because it collects so much data so quickly, the system could dramatically speed up the testing of new drugs for Parkinson’s disease.

How soon could such a system be deployed? Katabi said it would not require US Food and Drug Administration approval because the system only collects data.

“The device doesn’t make medical decisions, only measurements,” she said. “In principle, this should be possible very soon.”

David Lundquist, MD, Chief Medical Officer, Augmedix

Burnout is a growing situation that is slowly undermining the productivity of physicians and their staff. And in recent years, the situation has worsened as patient demands, documentation and regulatory requirements increase.

Added to the situation are the challenges of adding technology, the need to be virtual and meet patients where they are, and the need to keep up with the ever-changing information and landscape in terms of what our patients expect of us.

Kirk Davis, executive director of operations at Dignity Health, calls it time poverty, as demands on doctors increase, calling for more time in the office and less time at home with family, tipping the scales from work-life balance to burnout.

Those who become doctors go into medicine because it gives them meaning and purpose. Yet many feel their altruistic reasons have been squeezed out of the field of medicine, which has become very robotic and documentation-centric as relationships with patients are less emphasized. Add to this the challenges of VURs, which determine reimbursements for services provided, and it’s easy to see how much of the work doctors do seems unrelated to patient care.

Distracted doctors

I compare the application of technology in medicine to distracted drivers and their cell phones. Cell phones are great, but when behind the wheel drivers need to focus on the road and not texting and doing stupid things that will keep them from being safe.

And I think in many ways our doctors and our staff are distracted clinicians. They have technology that barks at them and tells them to pay attention and watch tasks, alerts, and information. And during the pandemic, we’ve added video visits, forcing doctors to fumble with another layer of technology to interact with patients, but alienating them even further in some ways.

On top of that, add requirements for EHRs (electronic health records) and documentation; no wonder our docs are distracted. More and more clinicians are retiring early, changing professions, reporting burnout and depression, and even committing suicide.

Can technology ease the burden?

The promise of technology in medicine certainly makes sense. We see it in other industries, making it more efficient to book travel, find a restaurant, and figure out where we’re going to eat or buy movie tickets or whatever in our lives which has been made a bit more accessible and easier to do.

And yet, in healthcare, it feels like the promise of technology has yet to deliver. We are a bit behind other industries. Companies were already hosting video teleconferences, but before COVID, virtual tours were only tried on a small scale. The pandemic has forced clinicians to quickly adopt virtual visits. And while virtual visits may not be the solution for all patients, it is a solution for many, as providers and patients use available technology to facilitate the patient-provider contact journey.

Do algorithms replace experience?

On the one hand, technology makes patients safer. Data-driven programs provide predictive modeling, and some doctors use drop-down menus to make decisions. But when do years of training and experience trump algorithms? When data replaces experience, does it make sense at work as physicians lose a sense of the relevance of their training and experience? When does a doctor rely on his training and experience and not the data? We are still trying to figure that out.

But at the end of the day, we’re still dealing with unpredictable humans who may face stressors contributing to their condition that the computer can’t account for.

As humans, we have this unique ability to take a lot of complex data and put it together and find the nuance in it all. And I think computers and technology and automation can do some of the heavy lifting. And when we couple that with our unique humanity, we can arrive at a patient-centered diagnosis for the person sitting across from us versus a generalized response.

The electronic health record

Nowhere has the technology been expanded to meet documentation and regulatory requirements more than the EHR. From dictaphone and transcriptionists to voice to text, from voice to transcription in the EHR, to the use of scribes, we are seeing an increased use of technology to work in the EHR.

Technology has helped clinicians stay on top of charts instead of working late and having piles of incomplete paper charts on their desks.

Patients are also embracing this technology because it improves access, speeds up care and, probably most importantly, makes things more convenient for them. Because all records are just a click away, there is never the risk of a misplaced chart. And a doctor on duty has access to home records.

Technology can support work-life balance.

Technology can make it easier for patients to see their clinicians and feel more comfortable. Technology can help fill staff shortages. And technology can help doctors work at the top of their license and work with patients the way we want. If we integrate the right technology into our daily lives, it becomes a blessing.

In my opinion, technology is our North Star and we must embrace it.

Opponents of electric vehicles (EVs) often point to the unholy trinity of infrastructure, range, and price. Even if you’re an affluent city dweller with access to endless outlets, charging times still require between 15 minutes and 12 hours. This factor turns many potential EV users off, but MIT researchers may have found a solution to this charging conundrum.

In an article published by MIT (Massachusetts Institute of Technology) Donald Sadoway (along with 15 other authors from Peking University, Yunnan University, Wuhan University of Technology, University of Louisville, from the University of Waterloo and Argonne National Laboratory), the materials chemistry professor claims to have found a cheap solution to expensive lithium-ion batteries.

“I wanted to invent something that was better, much better, than lithium-ion batteries for small-scale stationary storage, and ultimately automotive. [uses]Sadoway admitted.

To find a suitable substitute for volatile lithium, Sadoway turned to the second most commercially available and abundant metal on Earth: aluminum. Then the MIT professor identified the cheapest non-metal available, sulfur, as the battery’s other electrode. To relay the ions between the two points, Sadoway adopted a molten salt electrolyte. While the battery composition prioritizes cost effectiveness and easily accessible resources, Sadoway cites several additional benefits.

“The ingredients are cheap and the thing is for sure – it can’t burn,” Sadoway proclaimed.

However, the aluminum-sulfur battery still appreciates heat. Studies have shown that the device actually charges 25 times faster at 110 degrees Celsius (230 degrees Fahrenheit) than at 25 C (77 F). In addition, the battery generates heat during charging and discharging periods. This allows it to maintain optimum operating temperature while preventing the saline solution from freezing.

The molten salt electrolyte also dissolves accumulated metal dendrites, which can spread across both electrodes over time and cause shortages. This cheap and stable battery may not end up in vehicles immediately, but Sadoway thinks it can help speed up charging times in the near future. Installed in the charging stations, the battery system could store energy before quickly returning it to customers, thus minimizing waiting times.

Sadoway has already licensed the system patents to his newly co-founded company, Avanti.

“The first order of business for the business is to demonstrate that it works at scale,” Sadoway confessed.

If these tests show promise, we hope the new technology will accelerate both charging times and electric motorcycle adoption in the near future.

It may pave the way for computing that mimics the brain and helps establish artificial intelligence

Artificial intelligence and machine learning can cause a real revolution in the way the world works today, but their development is hampered by the fact that the current state of the art in electronics does not correspond to the needs.

In a bid to develop devices capable of mimicking the functioning of neurons in the brain, researchers at the Indian Institute of Science, Bengaluru (IISc) have designed neuromorphic devices using organic materials that have not been used until now. ‘now. Their work since 2014 goes in this direction.

Organic materials were considered the poorest of the different types of materials in the manufacture of computer components because they were brittle and unstable. “We chose this genre as our horse for the race because we believed that if there was a way to solve these performance issues, the features we could squeeze out of these materials could blast everything out there,” Sreetosh says. Goswami from the Center for Nanosciences and Engineering (CeNSE), IISc.

He and his collaborators have published important articles in this field since 2017 in Natural materials, Nature’s nanotechnology, Advanced materials and Nature, establishing that organic materials can compute reliably and in some respects are even better than inorganic materials. “The molecular system (transition metal complexes of aromatic azo ligands) is the brainchild of my father, Professor Sreebrata Goswami,” says Dr Sreetosh Goswami in an email to The Hindu.

The plastic brain

The human brain that inspired the researchers in their work, in the words of Sreebrata Goswami, who is now with CeNSE, IISc, “significantly surpasses all artificial electronic analogues in learning, cognition and decision-making ability. “. Its remarkable performance consumes only 20 watts of power over a space of 1260 cc. Some of the properties it exhibits which are desirable include interconnection and reconfigurability.

“Brain neurons operate on the edge of chaos with a highly nonlinear feedback mechanism. We are looking for materials that can capture such properties, an elusive goal…” explains Professor Sreebrata Goswami.

Many features

Molecular materials are characterized by interactions between molecules and ions, which then exhibit a multidimensional landscape of parameter space that can be modified to develop appropriate functionalities. The question they posed in a recent article published in Advanced materials was whether they could manipulate these many-body interactions to achieve plasticity and reconfigurability in devices. To do this, they measured current-voltage curves as a function of temperature over a wide range. They could capture features spanning bipolar, unipolar, non-volatile, and volatile memristors.

In the words of Dr. Sreetosh Goswami, this is an “insane amount of variability”, to describe which, the group had to design a mathematical space that could allow for almost any possible characteristic variation desirable in neuromorphic devices. “The same device could work in both analog and digital regimes just by adjusting the activation energy,” says Dr Sreetosh Goswami.

make it work

The challenge was that during low-temperature measurements, in molecular memristors, the switching responses quenched or flattened out as the temperature was lowered. “We could make it work because our molecular devices are robust and the switching mechanisms have a thermodynamic component that still occurs even when the device is cooled,” says Santi Prasad Rath, who is a postdoc at CeNSE, IISc, and the first author of the article published in Advanced materials.

Dr Sreetosh Goswami says: “We are quite confident that we will be able to develop a functional neuromorphic platform based on our metal complexes which could be the world’s first molecular neuromorphic technology.

By KATE BRUMBACK – Associated Press

ATLANTA (AP) — A group of computer and election security experts are urging Georgia election officials to replace the state’s touchscreen voting machines with hand-marked paper ballots ahead of the midterm elections. -November warrant, citing what they call “serious threats” posed by an apparent violation of voting materials in one county.

The 13 experts sent a letter Thursday to members of the State Election Board and to Secretary of State Brad Raffensperger, who is a nonvoting member of the board. He urges them to immediately stop using the state’s Dominion Voting Systems touchscreen voting machines. It also suggests that they impose a particular type of post-election audit on the outcome of all races on the ballot.

The experts who sent the letter include academics and former state election officials and are not associated with efforts by former President Donald Trump and his allies to overturn the results of the 2020 presidential election.

People also read…

The midterm elections are only two months away. A switch to hand-marked paper ballots could easily be made by then, as state law already provides for their use as an emergency backup solution, the letter says.

State Election Board Chairman William Duffey responded in an email to The Associated Press that “the security of our election equipment is of paramount interest to the State Election Board, as is the integrity of the election process. in Georgia”. He noted that the alleged offense in Coffee County was being investigated by the Georgia Bureau of Investigation and investigators from the Secretary of State’s office and said the FBI had been asked to assist. .

“The investigation is active and ongoing,” Duffey wrote. “The information developed will be considered in assessing the impact of Coffee County’s conduct.”

Raffensperger’s office has repeatedly stated that Georgia’s elections remain secure due to the various security mechanisms in place. Spokesman Mike Hassinger said in an email that the office would respond “in a timely manner with due diligence” and that the response would be “directed to the authors, rather than leaked to the media for some sort of rhetorical advantage. “.

The apparent unauthorized copying of election materials in Coffee County occurred in January 2021. It is documented in emails, security camera footage and other recordings produced in response to subpoenas in a longstanding lawsuit that argues Georgia’s voting machines are vulnerable and should be replaced with hand-marked paper ballots.

These records show that a computer forensics team traveled to the rural county about 200 miles southeast of Atlanta on January 7, 2021 to forensically copy voting material. Emails show that Sidney Powell and other attorneys allied with Trump were involved in arranging the visit.

The security video also shows that Doug Logan and Jeff Lenberg, who were involved in broader efforts to cast doubt on the 2020 election results, visited the office later that month.

Experts who sent the letter on Thursday have long criticized Georgia’s voting machines, which print a paper ballot that includes a human-readable summary of the voter’s selections and a barcode read by a scanner to tally the votes. votes. They argue that the machines have already made elections more vulnerable to tampering because voters cannot read the barcode to verify that it accurately reflects their selections.

But copying and sharing Coffee County election data and software “increases both the risk of undetected cyberattacks against Georgia and the risk of accusations of voter fraud and voter manipulation,” the letter said.

The expert letter also cites the work of University of Michigan computer science professor J. Alex Halderman, who serves as an expert witness in the long-running voting machine lawsuit. He has identified what he says are security flaws in Georgia’s voting machines. The Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency issued an advisory in June based on Halderman’s findings.

In addition to urging a move to hand-marked paper ballots, experts say a statewide post-election audit, limiting risk, should be done on all races on the ballot. A risk mitigation audit essentially uses a statistical approach to ensure that the results reported correspond to the actual votes cast. Current rules require that only one statewide contest be audited.

At least some of the experts who signed the letter sent to the Georgia State Election Board last year sent a similar letter to the California secretary of state ahead of a recall election for state governor, calling for a rigorous audit of this competition. The Secretary of State did not act on the recommendations.

Technique without label discovered thanks to Texas A&M University to research

METAIRIE, La., September 7, 2022 /PRNewswire/ — A technique used to test THC levels in hemp plants has now been confirmed to also identify the sex of the plant accurately without disrupting the growth cycle. Search results at Texas A&M University create a critical expansion point and valuable new use for Mariposa Technology’s state-of-the-art software and database.

Called PAMAP (for Predictive Analytical Modeling Application for Plants), this innovative digital agricultural tool has undergone an extensive research and development process to test live hemp plants for THC levels, among other cannabinoids, on-farm. , to ensure plants stay below the federal THC legal limit (0.3%) for industrial hemp.

Mariposa Technology uses the technique, known as Raman Spectroscopy (RS), for rapid field testing of industrial and pharmacological hemp for THC levels. On-site testing at farms growing hemp crops provides farmers with affordable, accurate, and immediate test results and provides the opportunity to supplement the work of testing labs.

Critical Risk Management for Plant Sex and THC

Identifying the sex of the plant is critical for hemp growers because one male or hermaphrodite hemp plant can pollinate an entire farm of female plants and negatively impact cannabinoid production. Only female cannabis plants can produce buds (flowers). Although male plants can be visually identified at around 6-8 weeks of growth, this is labor intensive and threatens the investment to date in cultivation.

“This discovery will be a game-changer for hemp growers around the world,” said Michael Adler, co-founder and CEO of Mariposa Technology. “In the past, growers had to be carefully trained to identify the sex of a plant. This can cause problems if a plant is misidentified and takes time. This new technique takes all the guesswork out, letting farmers know what they have. planted, saving them time and money.” He noted that PAMAP also allows hemp growers to quickly test the THC levels of live plants on the farm, positioning them to harvest before the levels of THC are considered “hot” and above the federal limits.

In the past, growers had to cut samples, send them to a lab, and wait days or weeks for results. This exclusive database allows anyone to test plants anywhere in minutes, without damaging the plant, for both sex and THC.

Mariposa Technology spent over a year traveling across the country collecting data on different varieties of hemp and marijuana plants using an Agilent Raman handheld spectrometer. This large-scale database is now used in conjunction with proprietary software, allowing an Agilent Resolve device (available through a subscription to PAMAP and Mariposa Technology) to test the sex of plants and the THC levels of their crop.

Academic research partnership

The sex determination technique was discovered by researchers from Texas A&M University and Mariposa Technology and recently announced in an article published in the academic journal Molecules. The authors found that by using a handheld Raman spectrometer, they can probe the biochemistry of plants, allowing them to identify hermaphrodites with 98.7% accuracy and male and female plants with 100% accuracy. .

“We recently discovered that we can use Raman spectroscopy to differentiate young male and female plants,” said Dr. Dmitry Kurouski, assistant professor of biochemistry, biophysics and biomedical engineering at Texas A&M University. “This innovative approach to optical detection is based on the phenomenon of inelastic light scattering that occurs between incident photons and molecules present in the sample. And the best part is that you can test each sample while allowing it to continue to grow.”

Identify the sex of the plant

Hemp is a dioecious plant, that is, it produces male, female and hermaphroditic plants. Female plants develop appendages that contain cannabinoids, molecules that include delta-9-terahydrocannabinol (delta-9 THC), cannabidiol (CBD), and cannabigerol (CBG). Male plants do not develop these appendages, making them useless to hemp growers producing pharmaceutical hemp. Additionally, hermaphroditic plants develop characteristics of both sexes, which can drastically alter the cannabis population due to hermaphrodite-induced cross-fertilization. Therefore, cannabis growers want to identify and eliminate male and hermaphrodite plants, and industrial hemp growers want to identify and eliminate female and hermaphroditic plants.

“When we learned about the work Dr. Kurouski was doing with RS and hemp, we realized there was an opportunity to harness this science to help hemp growers around the world,” said John Roberts, III, co-founder and president of Mariposa Technology. “Our partnership with Texas A&M allows us to continue to provide farmers with the latest research and a revolutionary tool that puts the power back in their hands so they can improve plant performance year after year.”

Following the release of this important research, Roberts said the company plans to launch a new fundraiser in the coming weeks to fund further development and deployment of the technology.

Nigeria and other African countries under the platform of the Forum for China-Africa Cooperation (FOCAC) are deepening their cooperation with productive engagement that will benefit the country and the continent as China boosts science technology cooperation spatial. Reports by BINTA SHAMA.

China’s innovative development goes hand in hand with strengthening its space industry as well as building the capabilities of its allies.

While space activities are multifaceted and cover different sectors such as transport systems, infrastructure, communications, satellite navigation systems and planetary exploration, the construction of the Chinese space station, named Tiangong, or Heavenly Palace , frequently attracts international attention.

Taikonauts

China’s significant advances in this sector are making waves around the world. According to the records of the Chinese authorities, three crewed missions have already contributed to the construction of Tiangong. In June 2022, another crewed capsule went into orbit and docked there. It also completed the June 2021 and October 2021 arrivals. To represent mission members, China uses the lemma “taikonauts”, synonymous with astronauts, which is a combination of the Chinese term “taikong” (space) and from the Greek “nautes” (sailor).

A few days ago, the Chinese taikonauts would have started their work of establishing a habitable environment within the station by reconfiguring, among other things, the ventilation and the purification of the air. Meanwhile, a Long March carrier rocket, which will send the Wentian lab module to Tiangong, has been ferried to the launch pad in China’s southern island province of Hainan.

CASE

According to the Chinese Academy of Sciences (CAS), this module has experiment cabinets and an installation platform for extravehicular payloads. He also has a mechanical hand that can be used alone or connected to the larger one belonging to the management and control center, Tianhe.

According to George Tzogopoulos, China’s autonomy has defined its impressive space program for years. However, of course, cooperation remains the goal. The white paper “China’s Space Program: A 2021 Perspective”, published last January, uses the word “cooperation” 46 times. It refers to the central role of the UN in the management of space affairs. It emphasizes the importance of the Asia-Pacific Space Cooperation Organization (APSCO), an intergovernmental body headquartered in Beijing aimed at functioning as a cooperation mechanism for developing countries in the region, the G20 and the Shanghai Cooperation Organization (SCO).

Sharing remote sensing satellite data

Moreover, the white paper gives weight to the synergies within the BRICS. Already in August 2021, under the Indian presidency, the heads of the BRICS space agencies had signed an agreement to cooperate in the sharing of remote sensing satellite data. A few months later, in May 2022, the countries of the group, currently chaired by China, went further and officially launched a joint committee on space cooperation. In the same vein, BRICS leaders issued a statement in June in which they reaffirmed their support for ensuring the long-term sustainability of space activities and preventing an arms race in space.

The FOCAC Dakar 2022-2024 action plan calls on both parties to strengthen cooperation on space technologies. In addition, China will promote the application of space technology and infrastructure development in Africa and use the space industry to boost social development and improve people’s living standards. A relevant sub-forum under FOCAC should also be created.

It is on this premise that Nigeria stands to gain from Chinese space science technology. The National Space Research and Development Agency (NASRDA) is one of the research institutions established by the Nigerian government in May 1999 with an overall objective to pursue the development and application of space science and technology for the socio-economic advantages of Nigeria.

Nigerian space program

NASRDA Director General Dr. Halilu Shaba has been outspoken in Nigeria’s quest to liaise with willing partners to actualize all the benefits of the Nigerian space program for socio-economic development in Nigeria.

Dr. Shaba explained recently that the Agency is receptive to solution-oriented innovations with the economic strength and force required to ensure Nigeria’s pride among other nations in the space sector.

In 2003, Nigeria secured the launch of its first satellite, NigeriaSat-1, an Earth observation satellite that became part of the International Disaster Monitoring Constellation (DMC). Since then, Nigeria has launched a total of five satellites, three of which are still operational as of 2020. This includes the first satellite designed and built by engineers from African countries, NigeriaSat-X. There are, however, some technical shortcomings that Nigeria needs to address and this is where China can step in.

Emerging space programs

China is increasingly interested in investing in emerging space programs under its Belt and Road Initiative (BRI). Considering satellites as infrastructure, China often invests in the satellite capabilities of BRI countries. In 2018, Nigeria agreed to give a $550 million stake in state-owned satellite operator NigComSat to a Chinese satellite company, China Great Wall, to manufacture two communications satellites to be launched by China two years later. the signing of the final agreement.

This cooperation is sure to build Nigeria’s capacity and enhance its technical skills. Nigeria, however, needs more investment of funds as the current budget arrangements of the space agency may not take it far to achieve its goals.

China National Space Administration

Moreover, young people are not forgotten. The China National Space Administration (CNSA) is, among other things, building a space science exchange platform, allowing students to explore new modes of educational communication and enrich their knowledge. CNSA also organizes online training courses in China, Egypt and Ethiopia. Young Nigerians can also benefit from exchange programs with China.

The bigger China grows, the bigger its international footprint becomes. Technological achievements – expanding with the exploration of the cosmos – result from China’s systematic planning and emphasis on research, science and hard work. China is naturally creating promising new conditions for the country’s future progress and its relations with the world.

On March 4, Zhang Bainan, deputy to the National People’s Congress and deputy chief designer of China’s manned space program, expressed optimism that in 2022, China will accomplish major tasks in six areas of the Tiangong space station, would launch the Wentian and Mengtian laboratory modules. and completely completing the space station, to achieve the station’s first combined flight with six spacecraft and two crews of six taikonauts in orbit at the same time.

In-orbit service

According to Zhou Jianping, the space station will form a T-shaped configuration and operate in orbit for a long time. The in-orbit service life of the suit is not less than 10 years and can be extended through maintenance.

Zhou said scientists from all over the world will be welcome to participate in science experiment projects on the Chinese space station. China has already promoted the implementation of the first technical experimentation projects with the United Nations Office for Outer Space Affairs, and has also entered into relevant cooperation agreements with several national or regional research institutes in space science and technology.

Nigeria must take advantage of these opportunities especially now that it maintains very solid diplomatic relations with the Asian giant.

Aged care providers are having mixed results with new technologies and management systems and need better support to succeed, according to CompliSpace’s annual Aged Care Workforce Report .

The Impossible Task: Workers’ Views of Growing Eldercare Demands report by CompliSpace surveyed over 1,000 seniors to better understand workforce trends, challenges and needs within companies.

He revealed that 47% of workers have seen their organization adopt new technologies in the past year, including electronic health records, workforce management programs and e-learning platforms. .

However, a slight majority of 54% said the quality and efficiency of their work had improved with the new technology, while 15% actually saw a decrease in quality and efficiency in the provision of care to the elderly.

The report’s findings have raised concerns as vendors work towards new government regulations and compliance requirements.

Chief executive officer (CEO) of senior care technology provider InteliCare, Daniel Pilbrow, says organizations have been consistent in adopting new technologies, although external factors have impacted the deployment of new innovations in the care of the elderly.

“The care sector continues to grapple with current challenges including an aging population, growing elderly care needs and staffing shortages,” Mr Pilbrow said.

“Technology can be used to help relieve the pressures facing the healthcare industry. Technology adoption has been steady, with growth continuing despite the many challenges facing the industry and its workforce.
