While Living with COVID-19 campaign has kicked off in earnest, Seoul Viosys Co., Ltd. (KOSDAQ: 092190), a company specializing in optical semiconductors, provided Violeds Air Purifying Sterilizers that can reduce the indoor COVID-19 infection rate by 1/30 to 300 Korean facilities free of charge, with a good intention to support Korean small business owners. In addition, it announced that it would provide the Air Purifying Sterilizer license to the partners who can supply them worldwide.

Seoul Viosys conducted an air sterilization experiment based on the study of the Korea Central Disease Control Headquarters and the Korea Institute of Science and Technology (KIST), which found out that opening windows frequently can lower the infection rate. When compared to opening windows and ventilating every 10 minutes, the amount of ventilated air with the Violeds air purifier is 6 times bigger, which means that the virus concentration is lowered by 1/6. Along with that, the simulation results confirmed that the chance of infection could be reduced by 1/30. Based on this result, Seoul Viosys designed an air purifying sterilizer to minimize the floating of droplets by optimizing air flow. And it obtained KC certification for the safety of consumers.
A general air purifier HEPA filter can filter fine dust and droplets with a size of 0.3 micrometers (μm) or more. However, since the size of the COVID-19 virus is smaller than 0.1 μm, and the moisture-evaporated virus can pass through the HEPA filter, the general HEPA filters are inadequate to reduce COVID-19 infection. In contrast, the Violeds air purifying sterilizer designed with a triple filter structure can prevent the inflow of the virus by sterilizing 90% of them within 5 minutes, which were carried in droplets and attached to the filter surface. As Violeds technology is the world's first patented technology developed and mass-produced by Seoul Viosys, the license agreement is essential for the business.
"Just as people have the right to drink clean water, we should be able to breathe clean air in indoor spaces," said Lee Young-joo, CEO of Seoul Viosys. "With our Violeds air purifier sterilizers, I hope the government, construction companies, and large multi-use facilities will take an active role in restoring the daily life of people and bringing them back a little bit of happiness, like eating out and drinking a cup of tea."

Klarna Card reaches 5 million active customers19.3.2026 16:31:00 EET | Press release
Klarna, the global digital bank and payments provider, today announced that the Klarna Card has reached 5 million active customers globally, underscoring rapid adoption as consumers shift towards new forms of payment which provide more control over day-to-day money management. The card draws from the customer's own funds for everyday spending, with the option to spread the cost of a specific purchase, like a large appliance or a flight, when it makes sense to do so. The result is a card that offers genuine spending control without the long-term debt obligations that come with traditional credit cards. The card’s growth is reinforced by Klarna’s membership program. The program offers premium perks such as airport lounge access, travel insurance, and lifestyle subscriptions — without requiring users to take on debt, meet spending thresholds, or revolve balances. By separating everyday spending from rewards, Klarna is challenging the strings-attached model legacy banks have long relied on

Armis Launches First-of-Its-Kind Benchmark Report Warning of Critical Security Gaps in AI-Native Development19.3.2026 14:00:00 EET | Press release
Armis, the cyber exposure management & security company, is warning that the rapid enterprise adoption of AI-native development is outpacing critical security safeguards, leaving organizations exposed to systemic vulnerabilities. New research from Armis Labs’ Trusted Vibing Benchmark Report, which evaluates 18 leading generative AI models across 31 test scenarios, reveals a 100% failure rate in generating secure code. These vulnerabilities are most prevalent in high-risk areas like memory buffer overflows, design file uploads and authentication systems. Therefore, organizations should immediately implement AI-native application security controls to reduce risk. “The era of vibe coding is here, but speed should not come at the cost of security,” said Nadir Izrael, CTO and Co-Founder of Armis. “Our research finds that the worst offenders are the same ones selling security solutions for the very vulnerabilities their models create. If the industry continues to integrate autonomous code wi
