Dedication to science secures young lecturer professor title

HÀ NỘI — Phạm Vũ Hồng Sơn, 37, a lecturer at Hồ Chí Minh City University of Technology, has become the youngest Associate Professor at the university.

Sơn has been given the title after more than 50 scientific works published in prestigious domestic and foreign journals and two copyrights on software using artificial intelligence to manage construction safety and online bidding.

Sơn talked to Tiền Phong (Vanguard) newspaper about his most memorable study, “A Hybrid Bayesian Fuzzy-Game Model for Improving the Negotiation Effectiveness of Construction Material Procurement”, published in a magazine of American Society of Civil Engineers (ASCE).

“It was one of my first studies on Artificial Intelligence (AI) and Game Theory (GT),” he said.

Predicting the intentions of others is one of the biggest challenges, he said.

And the study has built a decision-making support system from a lot of information collected in the past and present to predict the strategy and bidding method of many competitors at the same time, thereby offering the most suitable price with a high winning rate, he added.

Currently, online bidding has been widely applied, he said.

There are some products, which prices change very quickly because they are highly dependent on user demand and input supply sources such as electricity, oil or metal prices. Therefore, a decision to choose the right purchase price greatly affects the profit of a business, he said.

The system can synthesise and analyse a lot of information at the same time to get an optimal pricing strategy, then negotiate or bid with many suppliers around the world to find the best purchase price, he said.

“My research team and I are still trying to perfect the system and hope to be able to commercialise it in the near future,” he said.

Sơn and his teammates have successfully developed Manaworker software that can be used on the web, Android and IOS operating systems, and connect to GPS to monitor and warn workers on construction sites of hazards.

After a trial application at a few construction sites, the workers’ safety violations have been significantly reduced. The result encouraged him to continue researching and integrating more new features for the software in the future, he said.

Time is priceless

“For me, scientific research does not have a fixed time. Research time will be unlimited. I could research at any time of the day,” Sơn said.

Even when he is driving, feeding his baby, teaching or going to bed, he is still thinking about the problem he is researching, he said.

“One day when I am giving a lecture, I suddenly have a good idea so I immediately write it down on paper,” he said.

He often stays up all night to do his research when he has a good idea, he said.

“Therefore, time is priceless for me,” he said.

Sơn also said the value of time in scientific research is also presented in the perseverance of each researcher because there are studies being applied immediately and have high contributions to society, but some studies have to take 20 to 50 years to be applied.

Talking about pressure when doing scientific research, Sơn said he often tells his students that the high expectations of society will also put some pressure on researchers, but if you want to become a genuine scientist, you must be responsible for your own choices, set your own goals and create the pressure to accomplish them.

“Above all, I feel very honoured when my dedication is recognised. It is also a spiritual encouragement for me to be more motivated in the process of research and teaching in the future,” he said. —

Typhoon Noru weakened on Wednesday morning after making landfall and wreaking havoc in central Vietnam, while heavy downpours are still in the forecast over the next few days.

The typhoon made landfall between Da Nang City and Quang Nam Province at around 3:30 am on Wednesday, unleashing winds of 103-133km per hour, according to the National Center for Hydro-meteorological Forecasting.

At 7:00 am the same day, the wind speed decreased to between 62 and 74km an hour.

The storm is expected to travel west in the next 12 hours and be downgraded to a tropical depression and later a low-pressure area.

Due to the influence of the storm, provinces in central Vietnam and the northern part of the Central Highlands recorded massive rainfall of about 200-300 millimeters on Tuesday night.

More downpours are forecast for these localities on Wednesday and Thursday, posing a high risk of flash floods and landslides in mountainous areas as well as serious flooding in low-lying locations.

On Wednesday morning, scores of uprooted trees were recorded in Da Nang, according to the observations of Tien Phong (Youth) newspaper reporters.

Many roofs of houses were also seen lying on the streets.

Some residents began cleaning up areas around their homes even though the city was still affected by strong winds.

In Quang Nam, residents also reported uprooted trees and blown-away roofs following the landfall of Noru.

Multiple houses were submerged as serious floods hit the province’s Phu Ninh and Tay Giang Districts.

In north-central Quang Tri Province, nearly 1,400 people in Vinh O Commune were isolated after a bridge was swept away by floodwaters.

Authorities in north-central Thua Thien-Hue Province reported that more than 70 houses had their roofs blown away and eight others collapsed during the storm.

Noru and its circulation affected the power supply to about 1.2 million households in the central and Central Highlands regions, according to Vietnam Electricity (EVN).

Concurrence of rain, high tide causes misery on Ho Chi Minh City streets

Published

on

A rainstorm triggered by the circulation of Typhoon Noru coincided with high tide peaking on the Saigon River on Tuesday afternoon, submerging roads and stalling vehicles in Ho Chi Minh City.

The water level in canals across Ho Chi Minh City began to rise and flow into the streets at around 5:00 pm.

As a result, several streets in low-lying District 7 such as Tran Xuan Soan and Huynh Tan Phat were dozens of centimeters below water, impeding traffic.

Many commuters tried to wade through the inundated routes, while several others ended up with broken-down vehicles.

Local vendors also struggled as floodwaters submerged their stalls.

“This road has been flooded every tidal season for more than ten years,” said Le Thi Ly, a 56-year-old resident of Huynh Tan Phat Street.

“Every time floodwaters flow into our houses, we have no choice but to move furniture to higher positions to avoid damage.

“I hope the local tidal sluice project will soon be operating so that we will be less miserable every high tide season.”

Ly, like many other local residents, had to use boards to keep water out of her house.

Vietnamese deputy foreign minister expelled from Party

Published

on

Vietnamese Deputy Minister of Foreign Affairs To Anh Dung was expelled from the Party following his arrest over the allegations of receiving bribes during the organization of repatriation flights during the COVID-19 pandemic.

Party General Secretary Nguyen Phu Trong chaired a meeting of the Party Central Committee’s Secretariat on Tuesday to consider the disciplinary actions against Deputy Minister Dung and Nguyen Quang Linh, assistant to the permanent deputy prime minister.

The Secretariat stated that Dung lacked responsibility and violated the Party’s regulations and state’s laws in directing and organizing repatriation flights for Vietnamese citizens abroad during the COVID-19 pandemic.

The deputy minister was also investigated and arrested on suspicion of bribery.

Meanwhile, Linh took advantage of his position, compromised working principles, and violated the Party’s regulations and the state’s laws during the selection of enterprises to organize repatriation flights during the COVID-19 pandemic.

Linh was apprehended later the same day on suspicion of receiving bribes during the organization of repatriation flights.

The violations of Dung and Linh resulted in serious consequences and adversely affected the reputation of the Party organization.

The Secretariat thus decided to expel both Dung and Linh from the Party.

The arrests of Dung and Linh were part of a wider investigation where officials were accused of taking bribes from Vietnamese citizens abroad who wanted to return to the country when commercial flights were not available during the coronavirus pandemic.

Since the Ministry of Public Security launched an investigation into the case in late January, a score have been prosecuted and detained, including many officials from the Ministry of Foreign Affairs, Ministry of Health, and Ministry of Transport, and former leaders and officials of the Immigration Department.

During a press meeting in June, investigators stated that the bribes were worth tens of billions of dong. (VND10 billion = US$421,100). 

Vietnam organized nearly 2,000 repatriation flights during the COVID-19 pandemic, according to the spokesperson of the Ministry of Public Security.
