Pensacola Durable Custom Sunrooms | Hurricane-Resistant Glass Designs Updated

Researchers in Korea have developed an ultrathin optical lens system that keeps digital images bright and legible even in direct sunlight, overcoming one of the main engineering hurdles preventing augmented reality glasses from looking and feeling like ordinary eyewear. The joint team from Pohang University of Science and Technology (POSTECH) and Samsung Research built a prototype featuring a 1.5-millimeter-thick waveguide—the transparent channel that guides light from a tiny projector into the wearer’s eye—using engineered nanostructures called metasurfaces. The findings were published Thursday in the journal Nature, according to the Ministry of Science and ICT. For years, technology giants from Meta and Apple to Google and Samsung have raced to build lightweight smart glasses capable of overlaying turn-by-turn directions, translations and messages onto the real world. However, engineers have struggled with a stubborn trade-off: widening the viewing zone so a user can glance around without losing the image typically causes light to scatter and leak out of the lens, leaving displ

President Lee Jae Myung's disapproval rating rose to 47 percent this week, surpassing his approval rating, a survey showed Thursday. In a survey of 1,001 adults nationwide conducted Monday through Wednesday, positive assessments of Lee's job performance fell 2 percentage points to 44 percent from two weeks earlier, according to the National Barometer Survey (NBS). Negative assessments rose 3 percentage points to 47 percent. Lee's disapproval rating had remained higher than his approval rating for several weeks before the trend reversed in the previous poll. The survey also showed that 51 percent of respondents said Lee should scale back his use of social media to directly communicate with the public on his policy direction, citing concerns that remarks made "without sufficient deliberation" could cause confusion. Another 42 percent supported his use of social media for communication. Support for the ruling Democratic Party of Korea fell 1 percentage point to 35 percent, while that of the main opposition People Power Party remained unchanged at 25 percent. The poll has a margin of error of p

Korea has much to gain from supporting refugees, including making a safer and more stable international environment, according to the United Nations' refugee agency representative in Afghanistan. During an interview with The Korea Times during his visit to Seoul, Tuesday, Arafat Jamal, the UN High Commissioner for Refugees' (UNHCR) representative in Afghanistan, said supporting countries such as Afghanistan is not simply an act of charity, but an investment in a more stable world. "Korea is a responsible member of the international community. And helping a country like Afghanistan is for global public good. I think that we can only gain if countries are more open and more willing to build international solidarity and to look beyond themselves," he said. Jamal expressed deep gratitude to the Korean government and people for their continued support, urging them "to continue to build solidarity with the world." Afghanistan's strategic location, bordering seven countries including China, Pakistan and Iran, makes its stability a matter of wider international concern, the U.N. official said. A

A police complaint was filed Thursday accusing ruling party Rep. Choi Min-hee of defamation for referring to journalists as "a pack of hyenas." The complaint against Choi of the Democratic Party of Korea (DPK) was filed with the Seoul Metropolitan Police Agency a week after the lawmaker made the comment in a KakaoTalk group chat while referring to an image of photo and video journalists covering a general meeting of DPK lawmakers. She also described the journalists as "doing everything to take videos that sow discord." The complainant, Lee Jong-bae, a former Seoul city councilmember affiliated with the main opposition People Power Party, said Choi's comments revealed her perception of the press and exposed a double standard that chants democracy but scorns journalists that cause discomfort. Choi held a press conference at the National Assembly on Wednesday and apologized for her remarks.

A research institute affiliated with Hankuk University of Foreign Studies (HUFS) hosted policy dialogues in Singapore and Malaysia last week to strengthen cooperation between Korea and the Association of Southeast Asian Nations (ASEAN). The university said Wednesday that the HUFS Institute for International Strategy (HIIS) organized the dialogues in collaboration with leading overseas universities and policy research institutions ahead of its official launch. The events brought together diplomatic, security and economic experts from Korea and ASEAN member states as part of the International Eminent Persons’ Track 1.5 Dialogue on Foreign Policy Strategy, an initiative led by Korea’s Ministry of Foreign Affairs. Participants explored strategic responses to the rapidly changing international order and discussed ways to deepen Korea-ASEAN ties. The Singapore Policy Dialogue was held Nov. 2 at Hotel Waterloo Singapore under the theme “Rethinking Foreign Policy Strategies in a Changing International Order: Perspectives from South Korea and ASEAN.” The event drew faculty members of the S

A joint research team from Kookmin University, Sungkyunkwan University and Hanyang University has developed highly efficient perovskite light-emitting diodes (LEDs) without the need for a separate post-synthetic ligand-exchange process. The findings were published in Advanced Functional Materials, an international journal in the field of materials science, under the title “Direct Integration of Conductive, Emissive Perovskite Nanocrystals into Efficient Light-Emitting Diodes Without Post-Synthetic Ligand Exchange.” The team was led by Kim Young-hoon, a professor in the Department of Chemistry at Kookmin University; Lee Bo-ram, a professor in the Department of Advanced Materials Science and Engineering at Sungkyunkwan University; and Lee Tae-kyung, a professor in the Department of Organic and Nano Engineering at Hanyang University. The three professors served as co-corresponding authors of the collaborative study. Lee Yu-bin, who has completed her master’s coursework at Kookmin University, also participated as a co-first author alongside Kim Ji-geon, a researcher at the university,

The global semiconductor upcycle, coupled with easing pressure from higher oil prices, is expected to lead to stronger consumption next year, a state-run think tank projected Thursday. The outlook came amid assessments that this year's global chip upcycle, driven by the artificial intelligence (AI) boom, has had a limited impact on domestic consumption due to the gradual spillover of its benefits, while higher oil prices have weighed more immediately on the room for spending. "Next year, the negative impact of oil price hikes is expected to gradually weaken, while the positive impact of the chip upcycle spreads, leading to stronger consumption compared with this year," the Korea Development Institute (KDI) said in a report. The KDI said bonuses and dividends paid by major chipmakers could also provide additional momentum for domestic consumption, although geopolitical uncertainties in the Middle East may pose some downside risks. Amid the potential challenges, the KDI advised the government to refrain from measures aimed at stimulating short-term spending and instead focus on improving e
