abbrevation

Imagine Chanyeol mistakenly thinking “istg” means “instagram.” He loves his Instagram and ends up writing the abbreviation at the end of each post as a sort of signature sign-off because it makes him feel cool. He doesn’t forget to add his favourite phrase, as well: “wtf” because he believes firmly in the message of “working that face.”

He receives an email just a few days later from Choi Siwon telling him not to forsake God’s sacred name and to please pray. Complete with Siwon’s personally-picked religious links and everything. Chanyeol appreciates Siwon’s concern but he’s still confused why he got the email in the first place. He replies with a “stfu” because he’s too lazy to write full-out “super thanks, friendly unicorn” (the highest of praises in his and Yixing’s dictionary).

He’s even more confused when he receives a box full of rosaries the next morning and a message that Siwon would be arriving within the hour with a prayerbook.

Sleep Stages? What is that?

Today we want to enlighten you with some information on sleep stages.

Yes, Sleep consists of stages. Generelly we can divide sleep into REM sleep and non-REM sleep. You may think something like: Who sais there are stages and why should there be some, because when I go to bed, I just sleep, I do not remember stages. Yes, they are not consciously perceived, but something that happens in your brain, and as we all know our brain dictates what our body does.

So what does REM mean and why do we divide sleep into REM and non-REM. REM is an abbrevation for rapid eye movement. It is literally a stage where your eyes make rapid movements. This REM sleep is occurring in cycles of 90-120 minutes and increases during the second half of the night. It is often associated with dreaming, which makes sense, as the brain sends similar signals as when it is awake. During this REM sleep the heart rate, body temperature and breathing rate increase though the muscles are paralyzed. So it seems that this stage does not help you at all with getting the rest you usually expect from sleep.  And you would be right, as there are not many negative consequences if you miss REM sleep. One of the major consequences of too little REM sleep though is that one’s ability to learn a complex task is reduced. 

What about non-REM sleep then? Why do we need that. Isn’t sleep = sleep? No. There are 3 stages of non- REM sleep. The first stage is what you feel when you fall asleep, so the drowsy sleep which occurs early in each sleep cycle and only makes up around 5% of your total sleep. This stage is marked by slowly rolling eyes, which can also open and close randomly. Also the brain waves slow down from the normal wakefulness to slower activityduring sleep. During this “falling asleep” one may still hear sounds and conversations, though not feel the urge to response, and if woken during this one may also be sure that one did not sleep at all. The following stage, stage 2, accounts for approximately 45-50% of your sleep. This is marked by our muscles relaxing even more. The brain shows somewhat of the same slow activity as in stage one, though there are bursts of activity, which are said to keep the body in sleep and protect from noises etc., and help with memory consolidation of what we experienced during the day. The last stage, stage three, is the stage of slow wave sleep. The sleep is now its deepest and we are the most unresponsive during this stage. It makes up 15-20% of the total sleep and is more prominent during the first half of the night. Additionally to the brian waves being the slowest during this stage also the body temperature, breathing rate and blood pressure are the lowest. Of the non-REM sleep this is the stage which contains most of dreaming. It is also the stage where sleep walking, night terrors and sleep talking are the most probable.

Now you know about the different stages of sleep. Good, but how does this help you to learn anything useful? Now. You progress during the night, if everything is optimal, through several sleep cycles. The sleep cycles start at stage 1, obviously, then stage 2 and 3, back to stage 2 and 1. Instead of waking up, whcih would break your cycle, you go to a REM stage and then back to stage 1, and so forth.The first sleep cycle usually is around 90 minutes and the following ones around 100 minutes. In the normal case you would go through 4 or 5 of those cycles. So, after a quick calculation you can say that your body requires you to sleep around 8,3 hours to be satisfied. What if your body does not get what it wants? Then youre tired.

Just as a tip for you to take wiht you from this whole story: You now know about the different non-REM stages and that you are not easily woken during stage 2 and 3. Try to set your alarm to a time where you probably will be in a light sleep phase, such as REM sleep, to wake up refreshed.

[150425] Park Sohyun's Love Game Part 11
  • DJ: I'm wondering, since you're the mathyung, have you ever felt behind the times? Especially with members like Sehun or Kai.
  • Xiumin: Uh... Well there is one thing that makes me feel that way. That... when you talk, it's called abbreviations, isn't it? Yes, that. Sometimes when they use words like that there are times I don't understand what they're talking about.
  • DJ: HAHAHA what, no way!
  • Guest: Xiumin is still young too! Maybe you're just not hearing them right?
  • Xiumin: There's that too, but I feel like I do live in a way that makes me behind the times.
  • DJ: Really???
  • Guest: But you know what things like Um-Ka* means, right?
  • Xiumin: Huh? ...I know what M-Ka means? (t/n: He's talking about the abbrev for M Countdown)
  • (DJ & Guest going crazy because they can't believe he doesn't know what that is)
  • DJ: OH MY GOSH Xiumiiiiin, fans please send him all the abbreviations you know!
  • Xiumin: Um, what does Um-Ka mean?
  • DJ & Guest: Oh my gosh are you serious right now oh my god
  • Guest: Actually no, the fact that you don't use abbreviations makes you more cool.
  • DJ: That's true, it's actually not a good thing to use those words.
  • Xiumin: Can I try to guess what it means?
  • DJ & Guest: Yes yes please do
  • Xiumin: Um-ka... (small voice) Umma Kawaii? (t/n: "Mom's cute") Is it something like that?
  • DJ & Guest: Kyaaaaa Umma Kawaiiiii~~~
  • (everyone laughs)
  • Xiumin: What is it actually?
  • DJ: When you don't have money and someone asks you 'how did you buy this' you say 'Um-ka', as in 'Mom's credit card'.
  • Xiumin: Oooh! Mom's credit card! I see...
  • *t/n: To clarify, Um-ka = Umma Card = Mom's credit card. Xiumin thought the 'ka' was for 'kawaii' which is cute in Japanese.

Guys, guys, guys I can’t breathe omg so

We have a website through which we submit our timesheets at work, and I’ve seen them use the abbrev. “ERP” before (Enterprise Resource Planning) but as a decades-long MMO player…. that’s not what it means when I see it. (Come on, everybody’s been subjected to a General Chat at least once in their lives, right?)

This is the front page today:

I can’t even any more.
