コロナ感染予防にリップクリームが効果(2020年10月10日) - Lip balm is effective in preventing corona infection (October 10, 2020)
This is a news talking how lip balms could be effective in the prevention of the spread of COVID-19 virus. 新型コロナウイルスの感染経路の一つであるつばの飛散防止について、リップクリームが効果的だとフランスの研究者らが発表しました。 研究はフランス・モンペリエ大学のアブカリアン教授らが行いました。会話中では特にPやBの発音の際、唇の間に唾液の糸ができ、それがつばとなって空気中に放出されます。しかし、リップクリームを塗ったところ唾液の糸はできにくくなり、人によっては飛散するつばの量が4分の1になったということです。 アブカリアン教授:「もし唇の表面の質を変えたらどうなるんだろうと思いました。研究では、保湿などに使うクリームを塗ると飛沫(ひまつ)の量が減ったんです」 音によって効果が異なるほか、効果自体も1分ほどしか持たないことから、リップクリームはマスクの代わりにはなりませんが、研究を続けていくとしています。 French researchers have announced that lip balm is effective in preventing the spread of the spit, which is one of the infection routes of the new coronavirus. The research was conducted by Professor Abcarian of the University of Montpellier, France. During conversations, especially when pronouncing P or B, a thread of saliva is formed between the lips, which becomes a spit and is released into the air. However, when lip balm was applied, it became difficult for the saliva threads to form, and for some people, the amount of scattered spit was reduced to one-fourth. Professor Abcarian: "I wondered what would happen if I changed the quality of the surface of my lips. In my research, applying a cream used for moisturizing reduced the amount of droplets (himatsu)." The effect differs depending on the sound, and the effect itself lasts only about 1 minute, so lip balm is not a substitute for a mask, but they will continue their research. -

「富岳」飛沫拡散を計算 “座り位置”で飛沫5倍に(2020年10月13日) - "Tomitake" calculated that the depending on the position of the seat, the droplet could be 5 times more (October 13, 2020)
This is the news explaining how droplets travel and the risk of exposure. スーパーコンピューター「富岳」を使った新型コロナ感染リスクの検証で、飲食店で隣同士に座って会話した場合は正面で会話するよりも5倍の飛沫(ひまつ)を浴びることが分かりました。 富岳が4人が飲食店で1分程度話をした場合を計算した飛沫の広がり方です。理化学研究所のチームリーダーを務める神戸大学の坪倉誠教授によりますと、感染者が横に座っていて話をした場合は、正面に座った場合の5倍の飛沫を受けることが分かりました。さらに、飛沫そのものも湿度が低ければ低いほど、下に落ちずに空中に漂う量が急激に増えることが分かりました。湿度30%の場合は、60%の場合の2倍以上の飛沫が1.8メートル先まで到達したということです。また、コンサートホールなどで、合唱をする場合は飛沫は直進するため前方の人ほどリスクが高まるほか、合唱で生まれた気流によって飛沫がより遠くまで届くということです。 In the verification of the risk of new corona infection using the supercomputer "Tomitake", it was found that when sitting next to each other at a restaurant and talking, they are exposed to five times as many droplets (himatsu) compared to when sitting and talking in front of each other. “Tomitake” calculated how the droplets spread when four people talked at a restaurant for about one minute. According to Professor Makoto Tsubokura of Kobe University, who is the team leader of RIKEN, it was found that when an infected person sits next to an individual and talks, he/she is exposed to five times as many droplets as when he/she sits in front of him/her. Furthermore, it was found that the lower the humidity of the droplets themselves, the more the droplets will be floating in the air without falling down. At a humidity of 30%, more than twice as many droplets, compared to the humidity at 60%, reached 1.8 meters away. Also, when a choir is singing in a concert hall, the droplets go straight forwards and thus the risk increases for the person in front, and the airflow created by the chorus causes the droplets to reach farther. -

Still Confused About Masks?
The main point of this news article is getting across the point that it is very important to wear face masks while in the public. It has many pieces of evidence to support the wearing of masks. It also covers a few great points which is does it matter what mask each individual wears, and also does wearing the mask protect you from covid-19, or the people around you from it? This is the reason why I chose this article. I have been questioning both of these points since covid-19 and mask wearing started. This article reveals just how important it is to wear a mask when you are in the public and around other individuals that are not considered within your “personal bubble”. Many people are struggling with life in the pandemic right now, but also they are not doing their part in slowing the spread by properly masking up in public. The news article is very important because most of the population doesn’t know everything about covid-19 since it is new to all of us. The article provides crucial information on how to stop the spread, and hopefully eliminate the covid-19 virus. In this article, there is no bias standing out to me. This article is a fact based article that provides scientifically proven information about the virus. All of the claims of this article has stated have been run by tests. For example, a test was run about how many respiratory droplets left one’s mouth when saying a simple phrase. Without a mask, there was a range from 20-500 micrometers generated. With a face mask, nearly all of the droplets were trapped by the face mask. The responsibility of the media during the covid-19 pandemic is to keep the population up to date and educated about the virus. The more educated the population is, the slower the virus will spread, because a fraction of the population that is informed will follow protocols and safety tips from the media. From this article, I learned that wearing a face mask is much more powerful than I thought it was. After learning this from the article, I will make sure to wear a face mask when I am around my friends or in the public 100% of the time. -

No Mask No Teach
Right now there is so much uncertainty with opening schools this Fall. One of the concerns is if teachers and students should be wearing masks or not. My sons school says they will not require masks for students. I am a teacher and the district I work for is saying all students and teachers must wear a mask. Teachers may wear a face-shield so that students can see our face and expressions. I started looking around for places that sell masks. A lot of them are overpriced so my plan is to sew myself a few for next year. I work with low-income students so I highly doubt they will be able to afford some. The California Teachers Association has sent out info-graphics including this one. It describes the distance a droplet can travel. Most classrooms are very small and it would be impossible for a teacher to avoid being within 6 feet of a student. With so much uncertainty right now it is difficult to know where we are all going to be in the Fall and what our education system will look like.
