1. Internet of Things : The World Will Become Like a Giant Nervous System
Professor Choi Seong-hyeon of the Department of Electrical and Information Engineering, who researches wireless networks , Wi-Fi, LTE, and IoT connectivity, gave a lecture on the present and future of the Internet of Things (IoT) .
IoT is a foundational technology that connects objects to understand and control real systems and physical phenomena, and is applied critically to autonomous vehicles , smart buildings , smart cities , the space industry, and more .
All home appliances are connected through Internet of Things technology. Users can control all of these with a single smart device.
Following smartphones, the number of internet-connected devices is increasing . In particular, home IoT devices and services have started to emerge recently . Various home appliances such as digital door locks , window open sensors , gas safety devices , electric plugs , lighting fixtures , refrigerators , air conditioners, and washing machines are connected to the Internet , and these devices can be controlled remotely using smartphones .
Communication technology is what enables the use of IoT devices . Currently, because IoT devices are used indoors, they utilize short-range wireless networks such as Wi-Fi, Bluetooth , ZigBee, Z-Wave, visible light communication , and acoustic communication .
These technologies cannot be used outdoors because the transmission distance is only tens of meters . Representative examples of long-distance communication for outdoor use are 4G and LTE technologies used in smartphones . These technologies can be used for low-cost , low-power IoT devices, but they are not suitable for the Internet of Small Things (IoST) . Recently, long-distance communication networks supporting transmission distances of 1 to tens of kilometers have been developed . It was explained that there are LTE-M and NB-IoT technologies , which are evolutions of existing methods, as well as completely new technologies such as LoRa and SigFox , which are connecting the Internet of Small Things at low speeds but with low power .
Professor Choi Seong-hyeon added, “Communication technology has been developed in various ways in terms of transmission distance and transmission speed . Depending on the IoT device, there is a suitable technology based on power consumption , price , and frequency . The key is when , where , and how to apply and use it . ”
Finally, “ 5G is being developed with a target of 2020 . “We are focusing on speeds faster than 4G , shorter support times, and enabling many devices to connect simultaneously in a single area,” he said. “If 5G technology is commercialized, the true era of IoT will arrive . A hyper-connected society where people are connected to people , people to things , and things to things in real time will be realized . ”
2. Individualized treatment , personalized gene therapy, and selective anticancer treatment are possible.
Secondly, a lecture on personalized healthcare was given by Professor Seo Jong-mo of the Department of Electrical and Information Engineering, who researches artificial vision devices , neuroprosthetics , and bio- MEMS .
As the relationship between genes, genetic material , and proteins was revealed , and as metabolism and signal transduction processes within the body were understood, the idea of "improving the discomfort of all patients" became the beginning of modern medicine .
In the past, drugs were researched by finding components with therapeutic effects in natural substances . However, now that we understand the body's metabolism and signaling processes, drugs are designed based on the molecular structures targeted for treatment . This method is highly effective in inhibiting the growth of cancer cells, thereby minimizing the side effects of anticancer treatment .
Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) convert information about different parts of the body into numerical values and display them as images . In the past, these were used to examine structural changes and the location of diseases, but currently, functional MRI analyzes these values to observe functional changes . The development of these technologies has made it possible to analyze the characteristics of individual patients and provide personalized medical care .
With the integration of engineering into medicine and the advancement of machinery, surgical methods and examination procedures have evolved efficiently . Development of equipment has advanced endoscopic surgical techniques, and the use of robots has made it possible to optimize the surgeon's intent by utilizing both hands and feet simultaneously . Advancements in diagnostic devices have enabled the rapid processing of large volumes, making rapid diagnosis and treatment possible . Furthermore , specific genetic testing allows us to understand the causes of cancer and how genetic mutations occur, enabling personalized treatment based on genes .
In response to a question asking whether diseases can be predicted through genetic testing, Professor Seo Jong-mo replied, “Currently, there are cases where certain cancers with a family history have been discovered . However, having a genetic abnormality does not necessarily mean that a disease will develop . In many cases, environmental factors must be added for a disease to develop,” adding, “If we can control genetic abnormalities, we can prevent diseases from developing when environmental factors are added . ”
3. Advancement of VR/AR and video rendering technologies, and efforts to create high-quality content are necessary.
For the third lecture, Professor Nam-Ik Cho of the Department of Electrical and Information Engineering, who researches digital signal processing , image processing , and image recognition, gave a presentation on virtual reality (VR) and augmented reality (AR) .
Virtual reality refers to an environment created using artificial technology that is similar to reality but not actually real , while augmented reality refers to overlaying virtual objects onto the real world . These technologies can be applied to various fields such as games , simulation training , entertainment , movies , and smart cities .
▲ A visitor to the exhibition hall is virtually experiencing an amusement ride through VR.
Research on virtual reality using VR glasses began in the 1950s . The goal of virtual reality technology is to provide a level of immersion indistinguishable from reality . To achieve this, graphics technology , 3D image acquisition technology , and high-resolution display technology are required .
Two- dimensional augmented reality has already been in use for a long time . To represent it in three dimensions, it is necessary to create images with different sizes and focal points depending on the viewing position, as well as sensor technology that identifies human intentions and actions , and interface technology between humans and machines .
Currently, devices of various levels are on the market and content is being developed . However, there are issues such as resolution where pixel grids are visible even in UHD video , device weight , battery life , chromatic aberration and image distortion caused by imperfect video and optical technologies , motion sickness due to parallax between movement and image representation , and high-resolution video transmission . Additionally , it is difficult for it to become mainstream due to a lack of content .
Professor Cho Nam-ik stated, “Although technology is not yet sufficient to support mass adoption , it can be used in education , new entertainment , military training , and psychological / rehabilitation therapy,” adding, “We must also strive to increase the amount of good content . ”
4. Autonomous Vehicles : Will Cars with Driving Intelligence Superior to Humans Emerge?
Professor Seung-Woo Seo of the Department of Electrical and Information Engineering gave a lecture on autonomous vehicles via video .
Recently, autonomous vehicle technology has moved beyond the initial research stage and entered the commercialization phase . It is projected that by around 2040 , 75% of vehicles worldwide will be autonomous . Limited autonomous driving technology, which requires driver intervention, is largely complete , and technology for driving on specific sections of highways is at a level just before mass production .
▲ Seoul National University autonomous vehicle
Research on autonomous vehicles is being conducted not only by traditional automakers such as Audi , Volvo , and Ford , but also by specialized internet /ICT companies like Google and Baidu , with the goal of commercialization by 2020. Audi successfully achieved autonomous driving on a highway section in early 2016 , and Google's self-driving car has achieved a driving record of over 5 million km on public roads .
This technology is expected to see improved environmental perception performance due to advancements in sensor technology and the utilization of various information provided by infrastructure via communication . Furthermore , it is anticipated that the development of artificial intelligence will enable driving intelligence that surpasses human capabilities .
However, autonomous driving is a socio - political issue intertwined with various fields such as society , economy , law , culture , and customs . If we want automobiles to drive in a rational manner, a social consensus on rational human behavior must be reached .

The Problem with AI is Not Performance, but Trust
CEO Kang Min-seung emphasized at Snowflake's World Tour Seoul that generative AI has entered a phase where "trust" rather than accuracy becomes the key competitive advantage. As AI is applied to various tasks including consultation, risk management, and operational automation, incorrect data, erroneous responses, and bias are creating actual business risks. He pointed out that enterprises must build a trust layer above AI. To achieve this, accurate data management, semantic structuring, governance, and prompt security are essential. He explained that AI is not merely an automation tool but a technology that reorganizes the entire organization's workflows and decision-making systems. Snowflake provides a platform that supports this trust-based AI operation, emphasizing that enterprises should build "trustworthy AI" rather than "intelligent AI."
