New way to predict the damage and aging of bridges by using DNA. technologies
Providing a diverse range of bridge maintenance information services via a platform that offers aging predictions based on AI
2023-02-21
(Press-News.org) The Korea Institute of Civil Engineering and Building Technology (KICT, President Kim Byung-Suk) announced that it has developed the D.N.A. (Data, Network, and AI) technologies to predict the levels of damage and aging of bridges for preventive maintenance.
As of 2021, the percentage of Korean bridges aged 30 years or more stands at a relatively low 12.5%. However, this ratio is expected to increase in the next decade to 39.3% by 2031 and rapidly spike up to 76.1% in 20 years. For the preemptive management of these aging bridges, the levels and characteristics of performance deterioration for each bridge need to be understood by accumulating comprehensive and strategic data as well as technology that can predict the degree of obsolescence of the bridges based on the collected data.
A KICT research team within the Department of Structural Engineering Research, led by Dr. Ki-Tae, Park, has garnered more than 5 million data elements either directly or indirectly related to aging of bridges from 2021 to 2022. An AI learning model was applied on the established data to develop a prediction curve algorithm that can forecast the spread of damage over time, including a carbonation model of the bridges. The credibility of the technology was further improved by securing additional data on the bridges using IoT technology onsite and from experimental data that considers the environmental conditions of Korea.
The developed bridge aging prediction technology incorporated artificial intelligence technologies to analyze aging data in order to forecast the future level of damage to the bridges. The prediction accuracy of the aging level assessment algorithm stands at 90.8% as of the end of 2022, which is expected to be further improved up to 95% by 2023. Within the international technical level, academic research is in progress and it was investigated with accuracy level of about 85% as of 2021.
KICT plans to provide the results derived from the developed bridge aging prediction technology via a platform where multiple customers can utilize the data. The BMAPS(Bridge Maintenance-Aided Platform Service) platform will offer prediction results and diverse bridge maintenance information services, such as the load-carrying capacity (the ability to support weight) predictions for aging small and medium-sized bridges. The platform will be open to the public in 2nd half of 2023. The platform will be offered in Korean for its use within Korea. In consideration of the development status, an English version of the platform will be prepared by 2024, through which international users can also benefit from the platform as a source of reference.
As the research findings can be used as an objective data source to calculate the maintenance costs of bridges, it will significantly contribute to the preventive maintenance of bridge facilities, thereby reducing massive potential maintenance costs that may occur in the future.
Dr. Ki-Tae, Park, the lead researcher, commented that “securing preventive maintenance information on bridges by using various data, AI, and network-based platform technologies will contribute to the longevity of bridges” and further added, “that the prediction services will expand in the future to include not only bridges but a wide range of infrastructure.”
The research was initiated by the support of the Ministry of Science and ICT and developed under a major KICT initiative, “Development of a Smart Maintenance Platform and Utilization Technologies for Old Bridge Structures based on D.N.A. (2021~2023).”

Despite the fact that we all start out as an egg cell in one of our mother’s ovaries, these human reproductive organs are surprisingly under-studied. Scientists have been working on creating in vitro models of human ovaries so that we can learn more about them and develop treatments for ovarian conditions, but most existing models use a combination of human and mouse cells, which do not faithfully replicate human ovary functions and take a long time to grow in the lab.

Engineering researchers at the University of Waterloo are successfully using a robot to help keep children with learning disabilities focused on their work.
This was one of the key results in a new study that also found both the youngsters and their instructors valued the positive classroom contributions made by the robot.
“There is definitely a great potential for using robots in the public education system,” said Dr. Kerstin Dautenhahn, a professor of electrical and computer engineering. “Overall, the findings imply ...

Most babies born to mothers with COVID-19 were separated after birth resulting in low breastfeeding and skin-to-skin contact rates during the height of the pandemic, according to a new global study.
The international research, led by Murdoch Children’s Research Institute in collaboration with the the European Society of Paediatric and Neonatal Intensive Care (ESPNIC), found that transmission of COVID-19 from mother to baby was rare and generally mild when it occurred. But despite this, almost half of all babies did not receive any breast milk, with ...

Social cohesion and connection decline in an ageing population, according to a new study of one of humanity’s closest relatives.
For decades, researchers have been observing the rhesus macaques on Cayo Santiago (known as “Monkey Island”) in Puerto Rico.
Recent research showed that female macaques “actively reduce” the size of their social networks and prioritise existing connections as they age – something also seen in humans.
The new study, by an international team led by the University of Exeter, examines how this affects the overall cohesion and connection of the groups older monkeys live in.

The Internet of Things (IoT) requires the installation free of time and space, therefore, needs independent power sources that are not restricted by batteries or power lines. Energy harvesting technology harvests wasted energy such as vibration, heat, light, and electromagnetic waves from everyday settings, such as automobiles, buildings, and home appliances, and converts it into electrical energy. Energy harvesters can generate sufficient electricity to run small electronic devices by harvesting ambient energy sources without an external power supply.

For many children, winter season comes with regular exposure to circulating viruses at school or daycare. And a warm forehead is often one of the first clear signs a child has caught a bug.
But some parents may not be properly measuring or responding to elevated temperatures in children, a new national poll suggests.
While most parents recognize that a low-grade fever helps a child’s body fight off infection, one in three would give fever-reducing medication for spiked temperatures below 100.4 – which isn’t recommended – according to the C.S. Mott Children’s Hospital National Poll on Children’s Health at University of Michigan Health.

Correspondence shows troubling interactions between U.S. officials and the alcohol industry
By Kimberly Flynn
PISCATAWAY, NJ — Growing evidence exists that the alcohol industry uses a variety of strategies to influence public policy in a way that is advantageous to its own corporate interests, rather than the interest of public health. Recent communication between employees of the National Institute on Alcohol Abuse and Alcoholism (NIAAA) and alcohol industry groups shows extensive interaction on policy-relevant scientific issues, according to a new study in the Journal of Studies on Alcohol and Drugs.
