The level of contamination in the washing machine is approximately five times higher than in the toilet. The laundry tank, is something we can pass by without knowing, that is invisible from the outside. However, after washing, the water in the gap remains with foreign substances, which in turn causes odors, various germs and molds in the washing machine to breed.
The two companies that lead washing machine technology in China solved the problem of laundry tank sterilization and deodorization by applying Violeds technology from Seoul Viosys. With high satisfaction, it will be expanded from high-end to low-end models.
Violeds technology, which is an optical semiconductor, is new concept of clean technology developed by Seoul Viosys since 2005 with SETi in the U.S. It is the Seoul Viosys’ 4,000 patented technology brands that prevent bacteria from occurring and proliferating with photons. More than 1,000 patents for application of Violeds have been secured and verified, and the company has succeeded in extending its life span to 50,000 hours. The company has started to supply air conditioner for air purification and water sterilization products such as water supply and water purifiers.
Meanwhile, Seoul Viosys obtained results from a research center at Korea University last month that Violeds technology sterilizes the coronavirus 99.9 percent. Seoul Viosys will launch a portable personal product within this month to prevent transmission through the air and the spread of viruses on various surfaces, including facial masks and will provide temporarily with its own brand until corona situation is resolved so that it can be used to quickly save people from the pandemics of world.
Executive vice president Chae Hon Kim, who leads the UV business at Seoul Viosys, said “There have been many difficulties in developing and mass-producing ultraviolet semiconductor UV LEDs for the first time in the world. We have been working with SETi, a U.S. venture company, since 2005, and we are happy that developed as a technology even to sterilize COVID-19 to help the world.”

New Daiichi Sankyo Data Underscore the Effect of Bempedoic Acid in the Real-World Management of Dyslipidemia and Cardiovascular risk28.8.2026 11:00:00 EEST | Press release
Daiichi Sankyo (TSE:4568) today announced new results from the MILOS study that demonstrate the real-world impact of bempedoic acid administered either alone or as a fixed-dose combination with ezetimibe, in the management of dyslipidaemia. Presented at the European Society of Cardiology Congress 2026 in Munich, the findings show that the clinically relevant reductions in low-density lipoprotein cholesterol (LDL-C) achieved within the first year of treatment are estimated to translate into clinically meaningful reductions in 10-year cardiovascular (CV) risk.1 The data further reinforce the clinical value of bempedoic acid, and its fixed-dose combination with ezetimibe, across a diverse range of patient subtypes, regardless of gender and glycaemic profile (diabetes, pre-diabetes, or normoglycemia).2,3 Key findings from the new analyses of the MILOS study include: 10-year CV risk estimate reduction: An analysis of 960 at-risk patients estimated that one year of bempedoic acid-add-on ther
