SAN DIEGO (KGTV) — Nearly three-quarters of the students in San Diego County are currently learning from home, and those numbers don’t make a lot of sense to MIT professor Martin Bazant.Bazant is one of the creators of the COVID-19 Indoor Safety Guideline. The free online tool simulates the fluid dynamics of respiratory droplets in various kinds of rooms to show users the risk of different indoor environments.“If you run the numbers for a typical classroom, especially if the students and the teachers are wearing masks, then the amount of time in the room can be very significant,” Bazant said. “Essentially those people could spend a week in the classroom and not have a problem.”Bazant says the six-foot rule that has largely determined which businesses can stay open is overly simplistic. In some cases, he says the rule creates a false sense of security. In other situations, he says it causes the closure of businesses or schools that could safely operate.“If you place nursing home beds six feet apart in a shared room, they are absolutely not safe,” he said. But he said well-ventilated classrooms, with teachers and students in masks, are another story.“It's only the United States where we follow the six-foot rule. That's given by the CDC. The World Health Organization all along has been saying one meter, which is about three feet. If you simply followed the one-meter rule, all our schools would be open, as they are in most of the world right now,” he said.Bazant and his colleague John Bush said they set out to design a tool that would reveal the risk of transmission based on science, not guesswork.Users start by selecting a room type, like a classroom or an airplane. From there, they can control a wide array of variables to dial in the risk, like the room size, the ceiling height, and the ventilation and filtration systems.From there, users can further tune the model by human behavior. How many people are in the room? Are they whispering, shouting or singing? How many are wearing masks?Mask usage is a critical component, Bazant says. The model quickly reveals the challenges of maskless activities in rooms with poor ventilation. Put five people without masks in a 400 square foot room with closed windows, and it becomes unsafe after 33 minutes.Bazant says studies on super spreader events show in indoor environments, the distance from an infected person doesn’t matter. Infected droplets spread and mix throughout the room like second-hand smoke from a cigarette.But with masks trapping droplets and diverting them upwards like a chimney, an environment like an airplane could be safe for several hours, according to the model. With more than 95% of the passengers and crew wearing surgical masks, a Boeing 737 could support 200 people -- around full capacity depending on the configuration -- for 18 hours. 2850

SAN DIEGO (KGTV) - One of La Jolla's most scenic spots is also the scene of a 20 year battle that has left the community divided.The Coastal Commission voted unanimously Thursday night to approve a measure to renew a 10-year permit to close the Children's Pool to human access during Harbor Seal Pupping season.The Children's Pool was built in 1931 to give kids a safe place to enjoy the beach.In the late 1990's, harbor seals moved in on the area creating conflict.Surveillance cameras captured visitors getting dangerously close to the seals causing the city to take action.In 2014, they decided to close the Children's Pool from December 15th through May 15th. This is typically the time period when mother seals use the beach to birth their calves.The California Coastal Commission agreed to try out this plan for five years.Dr. Jane Reldan, President of the Seal Conservancy, said the beach closure was an "elegant compromise." Reldan added that the closure happens during a time of year when it's cold and people don't want to go swimming anyways.Opponents say there's plenty of coastline for the seals to use and that it's time the Children's pool was given back to the kids. 1190

SAN DIEGO (KGTV) — Palomar College officials say almost all of its classes will be held remotely this fall and new online programs will be offered.The college said all fall classes will be held online except for Emergency Medical Education (EME) and Fire and Police Academies, which resumed in-person courses in May, and the Nursing program, which will start in-person classes in the fall.Some Microbiology labs will also meet in person.RELATED: University of San Diego sidelines plans for fall in-person coursesPalomar cited an uptick in coronavirus cases in San Diego County as the reason they've chosen to continue virtual learning."Protecting our students, faculty and staff is our top priority as we navigate the dynamic conditions of this health crisis," said Interim Superintendent/President Dr. Jack Kahn. "Palomar will continue to deliver stellar instruction in a remote learning format as we support students in pursuing their goals."RELATED: San Diego Unified School District announces detailed online learning planThe school will launch new online programs in the fall, including: cybersecurity, data analytics, public relations, alcohol and other drug studies, social work and human services, child development—child and family services, child development—school age assistant, child development—associate teacher, and medical professions preparation (non-credit).Those who do return to campus in the fall will be screened for body temperature and COVID-19 symptoms, the college says. Facial coverings and social distancing will also be enforced.Palomar could change its operating policies and procedures though as health guidelines and directives change, the school adds. 1693

SAN DIEGO (KGTV) — Parents who are concerned about their traditional school district’s ability to handle distance learning this fall are running into a roadblock when seeking other options: wait lists.School choice advocates say a growing number of California parents are seeking out charter schools that specialize in “nonclassroom-based” instruction because of their long track records in distance learning, but a new state law is essentially capping enrollment at pre-pandemic levels.“Tens of thousands families are in limbo right now,” said Jeff Rice, founder of the APLUS+ Network Association, an association of 85 nonclassroom-based California charters that specialize in personalized instruction.There are at least 13,000 students currently waitlisted throughout about two dozen of the association’s schools, Rice said.Advocates have launched petitions, urging lawmakers to scrap a provision in SB 98 that capped funding for all public schools -- including charter schools -- at February attendance levels.Schools are typically funded on a per pupil basis, but the cap means funding will not scale up as attendance grows.“Some [charter] schools have wait lists of 2,000,” said Jennifer Cauzza, executive director of the JCS Family of Charter Schools.Cauzza said she’s in contact with about 30 charter school executive directors and “all of them are capped.”About 300 of California’s 1300 publicly funded charter schools are classified as “nonclassroom-based,” Rice said. The term includes home school, online and hybrid models, and is somewhat of a misnomer because students often get some in-person instruction from a credentialed teacher.These tuition-free charter schools will operate wait lists on a lottery system, not a first-come basis, so parents still have time to apply.Otherwise, parents who want to homeschool their children have two other options, and both require the parent to act as the teacher, said Elisa Hilliard, who operates the Facebook page San Diego Homeschool Mom.Parents can file a PSA, a Private School Affidavit, and essentially open their own private school within their home. Parents select and teach their own curriculum, and must fund it themselves.Parents can also join a PSP, a Private School Satellite Program. These are umbrella organizations or co-ops of parents that assist with paperwork and help swap curriculums.Parents have until October to file a PSA, so families who are unable to get into a nonclassroom-based charter school may want to see how their traditional district school handles distance learning before going off on their own, Cauzza said. 2608

SAN DIEGO (KGTV) -- Pro-choice demonstrations gathered outside the federal courthouse in downtown San Diego Tuesday afternoon. The rally was one of hundreds that took place across the country as part of a "Stop the Bans" national day of action. The protests are in response to a law in Alabama that only makes abortion legal when the woman's life is at risk. Several other conservative southern and midwestern states are considering similar measures to restrict access to abortions. "It's a very personal thing, and it's something everybody should have the right to do, to choose yes, I'm going to keep this child or no, I'm not," said Cynthia Knoop. Activists, elected officials, and faith-based leaders chanted, sang songs, and vowed to "not take a step back.""I can't believe we're still fighting this fight and having this discussion. I'm scared for the future generation, the younger women," said Helen Zeldes.Two middle school students also attended. "A child is a ton of responsibility and not every woman wants to, not every woman is financially stable enough to, it should not be in the hands of male senators," said Kate Alberts.The girls said what's happening has been the topic of conversation at their school."Those people who want to have abortions, they can't physically, mentally, take care of a child at ages 16,17, if they've been raped, incest, whatever it is, and it just makes me so sad cause these men are deciding these laws and they don't truly care about the baby once it's born, but when it's a cell," said Marina Nicolaidias.Abortion opponents see what's happening in Alabama and other states as progress. "What we have to remember is that nobody should have the right to take another person's life, and ultimately that's what this is, life begins at conception and when you do have an abortion, you're ending that life," said Marie Frederick, who works with Students for Life and other pro-life groups. Frederick said it's good that a national conversation is happening. "I think when you make a ban on abortion all across the nation; eventually, hopefully, you also need to implement resources for women, support for women I think workplaces need to be more open to women having pregnancies," said Frederick. Wednesday, pro-life groups are planning to protest outside a San Diego medical waste company that partners with Planned Parenthood. 2380
