アメリカアフターピル飲んだ時の話する

なんか流行ってるし、腐女子お気持ち表明よりは有用だと思うので書いておく。

ダラス駐在になった旦那に帯同した2年前の話。

値段や細かい事は当時の日記メモから書き起こしてみた。

子供は二人いて、二人目妊娠中に子宮トラブルがあって産後に今後の妊娠危険と言われていた。

避妊方法は当時コンドームのみ。

長子妊娠前に使ってた低用量ピルか、もしくはミレーナなど別の方法も併用したかったけど

慣れない英語婦人科に行く勇気が出ずに二の足を踏んでいたところ。

現在帰国したので低用量ピルコンドーム併用。

コトが終わって抜いた時に何か液体が出てきた感覚、明るくして見てみたらゴムの先端が破けていた。

シャワーを浴びて、モーニングアフターピル 英語 で検索emergency contraceptiveと呼ぶ事を知る。

今度はwhere can i get emergency contraceptiveと近所の地名検索してみたら、Targetで買えるらしい。

TargetWalmart匹敵するチェーン店で、近所の店舗は中にCVSという大手薬局が併設されている。

そこでPlan Bというのを買えばいいらしい。

翌日11時、開店と同時にCVSに行ってみたらカウンターにはでかいおっさん

すみません女性相談したいんだけど…と言うと奥から更にでかいテキサスサイズのお姉さんが出てくる。

お姉さんにググった時に出てきたPlanBの画像を見せると、どこからか白地に青の同じ箱を持ってきてくれた。

大丈夫よ、これを飲めばパーフェクトだからちょっと小声で慰めのような言葉をかけてくれる。

吐き気はしやすい方?と聞かれ、そうでもないと答えると、

もし必要ならもう一度来てね、今日明日いるから私を呼んでと胸の名札を指差す。

会計は50ドルくらいで、インフルエンザ予防接種クーポンがついてきた。

から何だか変に緊張して何も食べていなかったので、一旦COSTCOに行ってホットドッグを食べる。

ピルの箱を開けて錠剤を飲み、旦那に緊急避妊薬を飲んだ事と吐き気がする可能性が高い事を連絡し、帰宅

子供学校が終わり帰ってくる時間までは問題なかったが、夕食前になって怠さと吐き気

夕食作りは途中であきらめ、子供にはちょっと頭が痛いと言って横になる。

子供はこういう時UberEatsでタコスを頼めるので、階下で隠れて喜んでいる声が聞こえた。

船酔いのような吐き気がするが、吐く程ではない。

タコスを食べた子供達のスプラの音と歓声が聞こえるが、その声でやや頭痛がする。

旦那帰宅自分と私の分の夕食を買ってきてくれたので数口手を付けるがレタス外食べる気がしない。

低用量ピルは長く飲んでいたが、用量が多いからか最初に超えないといけないあの副作用よりきつい。

頭を冷やして就寝。

翌日、やや吐き気習い事の送迎だけこなして家事放棄

翌々日朝、茶色みがかった出血。昼に赤い出血生理よりはずっと少ない。

消退出血があった事で緊急避妊薬がちゃんと働いてくれたとひと安心

吐き気はないが、風邪の前のような怠さが残っていた。

これをまとめるに当たって調べてみたが、レボノルゲストレル1.5mgでノルレボと同じらしい。

手に入れるまでスムーズだったので、72時間というタイムリミットがあっても躓くところはなかった。

フェミニズムおかしな方向にいってリプロダクティブ・ヘルスライツについてあまり議論されないのが最近つらい。

楽園こちら側」の「事実に誠意を」をほぼdeepLで翻訳してみた その2

その1https://anond.hatelabo.jp/20200327214055

12 Dr. Hiroshi Nishiura is one of the few professionals of mathematical models of infectious diseases in Japan, and it is well known that his ability is outstanding. However, many people don't understand mathematical models themselves (I must confess that I can't say that I understand all of the findings because I'm not a professional of mathematical models either), so his findings and comments are easily deified. Because the contents of the mathematical model are a complete black box to many people, it makes it seem like the oracle is coming out like a shrine's oracle. Much of Japan's infection control policy relies on the Nishiura theory. So there is nothing wrong with that, but one of the problems in Japan is that there is no plan B in case plan A goes bust. Dr. Nishiura is an excellent scholar. It is not God. Hence the need to have that Plan B with the possibility of making a mistake. I am greatly concerned that bureaucrats and politicians who are prone to infallibilism will mistake science for an oracle. It is only when falsifiability is assured that science can continue to be scientific.

感想おみくじ神託が同じoracleだったので変な文章になったが直していない。

13 数理モデル演繹法活用産物である演繹法帰納法アブダクションで補完するのが、学問の基本であり、臨床医学常識である演繹法的にどんなに正しく見えても実はそれは違っていた、ということはこの業界ではよくあることなのだ。ヘーゲルマルクスのような巨大な知性でも演繹法オンリーでは間違うのである

Mathematical models are the product of deductive methods. The deductive method is complemented by the inductive or abduction method, which is the basis of scholarship and the common sense of clinical medicine. It's a common occurrence in this industry that no matter how deducibly correct it may seem, it's actually not true. Even a huge intellect like Hegel or Marx can make a mistake by deduction alone.

感想:「蓋を開けてみれば」を「実はそれは」に変更した。

14 モデルを使うな、といっているのでは決してない。ぼく自身モデルを用いて論文を書く。しかし、モデル無謬ではなく、そこには前提である仮定があり、仮定はしばしば間違っている。グラム染色活用するとは、グラム染色にできないこと、分からないことを知悉していることであり、グラム染色万能論者にグラム染色は使えない。同じことだ。英国でも数理モデル活用されているが、だからこそ英国人はその結語には非常に懐疑的で、常に反論異論が起きている。健全科学的な態度である

 I'm not saying don't use the model at all. I myself write a paper using a model. However, the model is not infallible, there are assumptions that are assumptions, and the assumptions are often wrong. Making use of Gram's stain means having full knowledge of what Gram's stain cannot do and does not understand, and Gram's stain cannot be used by Gram's stain universalists. It's the same thing. Mathematical models are also utilized in the UK, which is why Brits are very sceptical of their conclusions, and there are always counter-arguments and objections. It is a sound and scientific attitude.

感想:「前提たる仮定」がうまく訳せていなかったので「前提である仮定」にしたが、assumptions that are assumptionsになってしまった。

英国人は」がないと主語がIになってしまったので追加した。しかBritsじゃ意味違うよ。もっと正しく訳してくれない?

15 Japan's "now" is a well-controlled state of infection, which is much better than Wuhan at its worst, or Italy, Spain, France, England, or New York at the present time. The problem is that it doesn't guarantee that it will "always work".

感想特にない。便利だなあ。

16 懸念されるのは東京だ。感染報告が増えたことだけが問題なのではない。クラスター形成できない、トレースできない感染者が増えているのが問題である。そして、その陽性患者数に比べて検査数がずっと少ない。47人の感染者を捕捉するために100人未満(陽性者の検査日が不明だが、おそらくこのへんだろう)しか検査していないのは少なすぎる。

It is Tokyo that is of concern. The increase in reports of infection is not the only problem. The problem is that more and more infected people are unable to form clusters and cannot be traced. And the number of tests is much lower than that number of positive cases; it's too little that they only tested less than 100 people (the date of testing for the positives is unknown, but it's probably around here) to capture 47 infected people.

Again, it's not necessary to figure out all the infected people. However, it is troubling that the flow of infection, movement and clusters are out of sight. Therefore, the threshold for testing must be lowered in Tokyo. The threshold for testing varies with the circumstances. That's what I explained with the Korean example. Sticking to the Ministry of Health, Labour and Welfare's "standards" will lead to a misunderstanding of the phenomenon itself. Already in the Kansai region, infected people have been found with taste and smell abnormalities, and clusters have been detected from there. I would like to make more use of the athletic sensibilities of these clinicians. I'm not sure "where" in Tokyo is the barrier to lowering the number of inspections, but that barrier needs to be removed immediately.

感想:「捕捉するのに」を「捕捉するために」に変更した。多分これでいいと思う。思いたい。

アスチュートathleticになっているのはどう反応したらいいかからない。

17 This conceptual diagram that everyone is looking at - lowering the peak of the infection and shifting it to the side. This is all a product of deduction, and I don't know if it's really true. As mentioned above, the UK estimates already suggest that this is not enough. It is possible that the damage that was shifted to the side could simply be "extra-long damage".

感想特に言うことはない。便利だなあ。

18  そして、ここが肝心なのだが、ピークを下げるという理念が、「ピークを下げなければいけない」という観念になり、「ピークは下がっているはずだ」という確信になり、「ピークは起きていないんだ」という自己暗示に転じてはいけないということだ。プランAに固執する日本あるあるの失敗のパターンで、ダイヤモンドプリンセスでは「二次感染が起きてはいけない」が「起きているはずがない」に転じてノーガード下船を許してしまった。「ピークが起きてはいけない」が「ピークなんて見たくない」にならないように現実を見据える必要がある。たとえ、それが我々の見たくない不都合な真実であったとしても。

And this is the key point: the idea of lowering the peak should not become the notion that the peak must be lowered, or the belief that the peak must be lowered, or the self-implication that the peak is not happening. In a pattern of Japanese failure to stick to Plan A, Diamond Princess allowed no-guard disembarkation by changing "secondary infection should not occur" to "it can't have happened". We need to keep our eyes on reality so that "peak shouldn't happen" doesn't become "I don't want to see a peak. Even if it is an inconvenient truth that we don't want to see.

感想:mustが違う文脈で二回出てきている。よくわかるように変更したいものだ。

カギカッコがないとうまく訳せなかったので追加しているが、なぜかカッコ閉じるがいくつか抜けている。この箇所以外にも抜けがある。

19 Repeatedly. It's common knowledge in this industry that deductive methods are complemented by inductive methods. Nevertheless, PCR is often false-negative and has little power to determine the status of infection. That's why "testing everything" is so wrong. However, a serum test measuring immunoglobulin IgM and IgG would provide a more accurate picture of the "status of infection in the population. This, however, is not infallible. It is difficult to use for individual cases because it misses early infection, which is why it misses early HIV infection.Whether antibody testing is useful in individual cases remains to be tested, but it is well suited for epidemiological studies on a population basis. Roughly speaking, we can confirm whether the "infection is rampant" in Tokyo right now, or whether it's just an unfounded fear.

前例としては、ロンドンの血清検査で09年パンデミックインフルエンザが従来予測10倍起きていたことが血清検査でわかっている。抗体検査アウトブレイクのあとで事後的に行うことが多いが、慢性的パンデミックになりつつあるCOVID-19については、「今」こそが検証ポイントといって良い。

As a precedent, serology tests in London showed that the 2009 pandemic flu was 10 times more likely than previously predicted. Antibody testing is often performed after an outbreak, but now is a good time to examine COVID-19, which is becoming a chronic pandemic.

感想:「前例はあって」を「前例としては」に変えた。「前例はある。なおかつロンドンで〜10倍起きていた」になってしまたからだ。

20 英国さらアグレッシブだ。家庭で抗体検査を行い、「感染である」とわかればそれを自宅での自己隔離根拠に使おうというのだ。ロックダウンが起きている中で、検査陰性は「自己隔離不要」を意味しないため、その戦略に欠陥はある。が、考え方としては「感染全体を抑え込みたい」というもので、検討価値はあると思う。

The UK is even more aggressive. The idea is to test for antibodies at home, and if they are found to be infected, they will use it as a basis for self-isolation at home. That strategy is flawed because with the lockdown in place, a negative test does not mean "no self-sequestration". However, the idea is that we want to control the infection as a whole, and I think it is worth considering.

感想:「戦略に穴はある」を「戦略に欠陥はある」に変えた。

21 東京でどのくらいの感染が起きているか帰納法確認必要であり、有用だ。その結果がどうなるかは預言者ではないぼくには分からない。が、どんな結果が出てきても、それを受け入れ、場合によっては自説を変えて、プランBに移行することにも躊躇しない態度が科学者には必要だ。科学者は、首尾一貫していないことにかけて、首尾一貫していなければならないのだ。形式においては首尾一貫していなくても、プリンシプルプロフェッショナリズムにおいて一貫しなければならないのだ。事実に誠意を。 

Inductive legal confirmation of how many infections are occurring in Tokyo is necessary and useful. I'm not a prophet, so I don't know what the outcome will be.However, no matter what the outcome, scientists need to accept it and not hesitate to change their thesis and move on to Plan B in some cases. Scientists have to be coherent in their inconsistencies.They may not be coherent in form, but they must be coherent in principles and professionalism. Good faith in the facts. 

感想:首尾一貫という言葉を使いすぎて文章をアホっぽくしてしまったが他にいい方法が思いつかない。朝三暮四理解してくれなかった。「自説を曲げ」は「自説を変えて」に変更した。

文章はもう少し整形できると思うがとりあえずこれで。

岩田健太郎先生とDeepLに敬意を。

差別表現慣用句でもNG」と言ってる人が「片手落ち連呼現実


しかし……

 ↓


最初ツイートを見たとき、私はこの人に同感して思わずいいねRTをしてしまったのですが、私は片腕を失った人間なので、後者ツイートを見たときにはとてもショックを受けてしまいました。

なんで差別表現がいけない事だと気付いている人が、自分差別表現にはかくも鈍感でいられるのだろう、、、もしかして自分みたいな人間差別されて当然なのだろうか、そう思われているのだろうか、、、いろいろな感情交錯して涙が止まらない。

たとえ慣用句であっても、悪意があってもなくても、いかなる差別表現も当然許されないのだという当たり前の感覚が、本当に当たり前のこととして皆さんに共有されてほしいと願うばかりです。この増田右手だけでブラインドタッチしています

福島原子力発電所CNNコメント欄 MIT科学者見解2【東日本巨大地震

When the diesel generators were gone, the reactor operators switched to emergency battery power. The batteries were designed as one of the backups to the backups, to provide power for cooling the core for 8 hours. And they did.

Within the 8 hours, another power source had to be found and connected to the power plant. The power grid was down due to the earthquake. The diesel generators were destroyed by the tsunami. So mobile diesel generators were trucked in.

This is where things started to go seriously wrong. The external power generators could not be connected to the power plant (the plugs did not fit). So after the batteries ran out, the residual heat could not be carried away any more.

At this point the plant operators begin to follow emergency procedures that are in place for a “loss of cooling event”. It is again a step along the “Depth of Defense” lines. The power to the cooling systems should never have failed completely, but it did, so they “retreat” to the next line of defense. All of this, however shocking it seems to us, is part of the day-to-day training you go through as an operator, right through to managing a core meltdown.

It was at this stage that people started to talk about core meltdown. Because at the end of the day, if cooling cannot be restored, the core will eventually melt (after hours or days), and the last line of defense, the core catcher and third containment, would come into play.

But the goal at this stage was to manage the core while it was heating up, and ensure that the first containment (the Zircaloy tubes that contains the nuclear fuel), as well as the second containment (our pressure cooker) remain intact and operational for as long as possible, to give the engineers time to fix the cooling systems.

Because cooling the core is such a big deal, the reactor has a number of cooling systems, each in multiple versions (the reactor water cleanup system, the decay heat removal, the reactor core isolating cooling, the standby liquid cooling system, and the emergency core cooling system). Which one failed when or did not fail is not clear at this point in time.

So imagine our pressure cooker on the stove, heat on low, but on. The operators use whatever cooling system capacity they have to get rid of as much heat as possible, but the pressure starts building up. The priority now is to maintain integrity of the first containment (keep temperature of the fuel rods below 2200°C), as well as the second containment, the pressure cooker. In order to maintain integrity of the pressure cooker (the second containment), the pressure has to be released from time to time. Because the ability to do that in an emergency is so important, the reactor has 11 pressure release valves. The operators now started venting steam from time to time to control the pressure. The temperature at this stage was about 550°C.

This is when the reports about “radiation leakage” starting coming in. I believe I explained above why venting the steam is theoretically the same as releasing radiation into the environment, but why it was and is not dangerous. The radioactive nitrogen as well as the noble gases do not pose a threat to human health.

At some stage during this venting, the explosion occurred. The explosion took place outside of the third containment (our “last line of defense”), and the reactor building. Remember that the reactor building has no function in keeping the radioactivity contained. It is not entirely clear yet what has happened, but this is the likely scenario: The operators decided to vent the steam from the pressure vessel not directly into the environment, but into the space between the third containment and the reactor building (to give the radioactivity in the steam more time to subside). The problem is that at the high temperatures that the core had reached at this stage, water molecules can “disassociate” into oxygen and hydrogen – an explosive mixture. And it did explode, outside the third containment, damaging the reactor building around. It was that sort of explosion, but inside the pressure vessel (because it was badly designed and not managed properly by the operators) that lead to the explosion of Chernobyl. This was never a risk at Fukushima. The problem of hydrogen-oxygen formation is one of the biggies when you design a power plant (if you are not Soviet, that is), so the reactor is build and operated in a way it cannot happen inside the containment. It happened outside, which was not intended but a possible scenario and OK, because it did not pose a risk for the containment.

So the pressure was under control, as steam was vented. Now, if you keep boiling your pot, the problem is that the water level will keep falling and falling. The core is covered by several meters of water in order to allow for some time to pass (hours, days) before it gets exposed. Once the rods start to be exposed at the top, the exposed parts will reach the critical temperature of 2200 °C after about 45 minutes. This is when the first containment, the Zircaloy tube, would fail.

And this started to happen. The cooling could not be restored before there was some (very limited, but still) damage to the casing of some of the fuel. The nuclear material itself was still intact, but the surrounding Zircaloy shell had started melting. What happened now is that some of the byproducts of the uranium decay – radioactive Cesium and Iodine – started to mix with the steam. The big problem, uranium, was still under control, because the uranium oxide rods were good until 3000 °C. It is confirmed that a very small amount of Cesium and Iodine was measured in the steam that was released into the atmosphere.

It seems this was the “go signal” for a major plan B. The small amounts of Cesium that were measured told the operators that the first containment on one of the rods somewhere was about to give. The Plan A had been to restore one of the regular cooling systems to the core. Why that failed is unclear. One plausible explanation is that the tsunami also took away / polluted all the clean water needed for the regular cooling systems.

The water used in the cooling system is very clean, demineralized (like distilled) water. The reason to use pure water is the above mentioned activation by the neutrons from the Uranium: Pure water does not get activated much, so stays practically radioactive-free. Dirt or salt in the water will absorb the neutrons quicker, becoming more radioactive. This has no effect whatsoever on the core – it does not care what it is cooled by. But it makes life more difficult for the operators and mechanics when they have to deal with activated (i.e. slightly radioactive) water.

But Plan A had failed – cooling systems down or additional clean water unavailable – so Plan B came into effect. This is what it looks like happened:

In order to prevent a core meltdown, the operators started to use sea water to cool the core. I am not quite sure if they flooded our pressure cooker with it (the second containment), or if they flooded the third containment, immersing the pressure cooker. But that is not relevant for us.

The point is that the nuclear fuel has now been cooled down. Because the chain reaction has been stopped a long time ago, there is only very little residual heat being produced now. The large amount of cooling water that has been used is sufficient to take up that heat. Because it is a lot of water, the core does not produce sufficient heat any more to produce any significant pressure. Also, boric acid has been added to the seawater. Boric acid is “liquid control rod”. Whatever decay is still going on, the Boron will capture the neutrons and further speed up the cooling down of the core.

The plant came close to a core meltdown. Here is the worst-case scenario that was avoided: If the seawater could not have been used for treatment, the operators would have continued to vent the water steam to avoid pressure buildup. The third containment would then have been completely sealed to allow the core meltdown to happen without releasing radioactive material. After the meltdown, there would have been a waiting period for the intermediate radioactive materials to decay inside the reactor, and all radioactive particles to settle on a surface inside the containment. The cooling system would have been restored eventually, and the molten core cooled to a manageable temperature. The containment would have been cleaned up on the inside. Then a messy job of removing the molten core from the containment would have begun, packing the (now solid again) fuel bit by bit into transportation containers to be shipped to processing plants. Depending on the damage, the block of the plant would then either be repaired or dismantled.

Now, where does that leave us?

・The plant is safe now and will stay safe.

Japan is looking at an INES Level 4 Accident: Nuclear accident with local consequences. That is bad for the company that owns the plant, but not for anyone else.

・Some radiation was released when the pressure vessel was vented. All radioactive isotopes from the activated steam have gone (decayed). A very small amount of Cesium was released, as well as Iodine. If you were sitting on top of the plants’ chimney when they were venting, you should probably give up smoking to return to your former life expectancy. The Cesium and Iodine isotopes were carried out to the sea and will never be seen again.

・There was some limited damage to the first containment. That means that some amounts of radioactive Cesium and Iodine will also be released into the cooling water, but no Uranium or other nasty stuff (the Uranium oxide does not “dissolve” in the water). There are facilities for treating the cooling water inside the third containment. The radioactive Cesium and Iodine will be removed there and eventually stored as radioactive waste in terminal storage.

・The seawater used as cooling water will be activated to some degree. Because the control rods are fully inserted, the Uranium chain reaction is not happening. That means the “main” nuclear reaction is not happening, thus not contributing to the activation. The intermediate radioactive materials (Cesium and Iodine) are also almost gone at this stage, because the Uranium decay was stopped a long time ago. This further reduces the activation. The bottom line is that there will be some low level of activation of the seawater, which will also be removed by the treatment facilities.

・The seawater will then be replaced over time with the “normal” cooling water

・The reactor core will then be dismantled and transported to a processing facility, just like during a regular fuel change.

Fuel rods and the entire plant will be checked for potential damage. This will take about 4-5 years.

・The safety systems on all Japanese plants will be upgraded to withstand a 9.0 earthquake and tsunami (or worse)

・I believe the most significant problem will be a prolonged power shortage. About half of Japan’s nuclear reactors will probably have to be inspected, reducing the nation’s power generating capacity by 15%. This will probably be covered by running gas power plants that are usually only used for peak loads to cover some of the base load as well. That will increase your electricity bill, as well as lead to potential power shortages during peak demand, in Japan.
