Chemistry

* * *

Friday morning.

Sitting in the kitchen, Jungwoo put food in the mouth of a spoon, tried to eat kimchi stew, and when he saw the pot that his brother's spoon kept coming back and forth, he stopped.

‘I'm going to have to eat it separately. ’

When I took a bowl and put it on a ladle, the dinner snorted.

“What are you so clean about? ”

“You need to pay attention to your hygiene. That's right. Don't pick up anything that rolls around my room. ”

“Am I the loser? ”

As the kitchen became noisy, Hong Ji-sook turned his head as he was watching TV in the living room.

“If you're not going to eat and fight, just get out. ”

The brawl between brothers evolved in an instant in the meadow of Hong Ji-suk.

In 30 minutes.

When Jungwoo finished preparing for work, he came down to the first floor and heard the news on TV.

- Large diurnal temperature variation, fine dust. Contrary to yesterday's clear skies, the concentration of ultradust today greatly exceeds the World Health Organization standard. Spring droughts are getting worse, so the meteorological authorities raise the alarm from dryness information to alarms.

I grabbed my tongue while keeping my gaze fixed on the news.

“Spring after spring is crazy. Dinner, take your mask. They gave me one at the reunion. ”

Jungwoo suddenly approached next to Hong Ji-suk.

“I gave you one. Why is it cold? What about me?"

“Oh, my God. You can buy it. ”

“I did. But, Mom, don't you have to take care of your oldest son running on the frontier? ”

I grabbed the dust mask on the living room table that I made for the sieve that Hong Ji-sook heard.

“Mom, I'm going to work! ”

“Hey, don't put that down! ”

Jungwoo, who put it on the porch, quickly said, wearing shoes.

“I've got a paycheck coming in. You can buy spring clothes. Buy me a hundred masks with it. Coming!”

Jungwoo ran out into the yard.

On the subway, quite a lot of people were wearing masks. Jungwoo looks out the window at the cloudy atmosphere and shakes his head.

High concentrations of ultrafine dust were found everywhere.

By the way, yesterday's news came out that the air is good like yesterday's. Since when has this become a news story? I was wrestling between the contaminated air and the filter for several days, and the clearer sky became stiff.

‘We'll have to install our system at home later. If Chan keeps snooping around like that, I'll be the only one left. ’

Whether I made money or got into an accident, my mother was very consistent. Your brother comes first, you come later. But what was unfair was that he had spent a lot of money on the store as collateral until he graduated from college.

"On the day I pay you back, I will ask you to treat me like a son!" ’

Jungwoo picked up his cell phone with his back against the rod near the train entrance. And I double-checked Yoon Yi Seol's text that came in late last night.

[I'm checking in on Saturday. What do you think, Jungwoo? Well, if you're coming, you can arrange a meeting with someone who can advise you on acting.]

Tea is a really big date request, so a smile came out.

A relaxing holiday. Asleep symptoms gradually subsided and are now more obsessed with improving habits than with intensive treatment in the clinic. I heard from the headmaster that she was in a similar position.

‘Falling. Well, maybe we can find an excuse to examine him in the hospital. ’

[It's me. Mr. Lee, where is the checklist available?]

I texted because I thought I was awake because it was past 8: 00. The answer came as soon as I expected.

[It doesn't matter where you're going tomorrow. It's Jungwoo's choice.]

It was a text that troubled me. Since Jung had to make a good reason, Jung decided to think more clearly and answer.

Arrived at the company at 8: 30.

Jung was sitting in the study room 1 because he still had time to prepare for today's improvements. Then, as the door opened, I saw a researcher from the filter team rush in.

Turning your head to look for you, you stand up in the corner of Jung.

“Why?”

“Jungwoo! Final inspection before the first bid. Team Leader Yu wants a grade 5 cleanliness rating. ”

“Grade 5, not 6? ”

The lower the level of grades classified by the Korea Filter Institute, the more cleanliness will increase. For three days from Tuesday to yesterday, Jungwoo applied a bacterial reduction catalyst throughout the 10-step filter to build a purification system that constitutes the hospital's neonatal or recovery room-level clean room.

That's grade six. A step up here is impossible in a short period of time without dramatic research.

In a hurry to get to the research lab at the Center for Materials Science, the filter team, of course, was dispensing Mei's demands.

“Can you believe it? What kind of immune isolating BCRs are we? ”

“That's what you said when you asked me to do the seventh grade. Other companies have the same goal. Who's your favorite when you take it to the next level? ”

Day after day, I encountered them and swallowed their groaning. I thought it might explode if I joined Kim Tae-san who hasn't come to work yet.

“I'll go talk to him. Director Yoo always has high expectations, but he doesn't make the impossible happen. ”

“No matter what you say · ·”

“Actually, I was hoping I could do five next week. ”

While House of Representatives needed the assumption that the half-membrane filter being redeveloped using the KG Electronics research team as a result of success, Jungwoo turned off the emergency fire first.

A month into the office of the sensor team, Jun Tsai, a key developer of the Purification AI, greeted him.

Welcome, Deputy Chief.

"Good morning. Is he in there?

The quasi-chain nods.

Knock, knock.

Only Rain

You knock on the team room door and check the mood of the sensor team. I noticed that this side is also busy going back. Looks like they've been instructed to do something. Jungwoo asked Jun Tsai.

What are you working on?

By placing an order to reduce the range of wireless sensor detection errors. If you have a moment, would you mind doing an inspection with me?

Sure, whatever.

It was a well with more accurate eyes than a sensor, so I've been helping them error test for days.

Come in.

Inside, Mei's voice is heard and she opens the door to weep. I saw her paying attention to the monitor.

You suddenly instructed both teams this morning.

I did.

I just want to check it out today, see if it's a good idea to keep improving after the first bid.

As Jungwoo cautiously gives his opinion, Mei coughs briefly with her hands on her mouth and replies.

Would you like to take a look at the information on the business side where you will be competing on Monday?

Mei turns the monitor to the right.

Competition in tender by a total of 4 companies, including KG chemistry. Dussf in China had heard of it before, and announced that Burke in Germany and Sumitochemistry in Japan were also involved.

Jungwoo was surprised to see a list of specialties from each company.

Berk creates a powerful filter to create an ISO CLASS 5, Class 5 cleanroom. Sumitochemistry was appealing to an automated system that could deliver customized air with an error zero precision sensor.

Dussf, one of the biggest competitors here, has offered much lower supply prices for performance to KG chemistry.

Unless these people have overadvertised, there is no chance of winning at the moment.

Yes. Never · ·

Mei coughs again. Cover your mouth and frown your eyes. I think my neck hurts. Jung said he knows.

I'll make grade 5 possible by the end of the week.

The bidding is on Monday, three days later. I tried to casually raise it by 0.5 points, but suddenly I needed 5 points. Jungwoo went out thinking about it.

3: 30 pm.

All team members were gathered in the Integration Lab to prepare for final inspection. Mei was informed that she was coming a little late, so she approached Joon-Tsai, who was adjusting her sensors.

Can you run the sensor once?

Jun Tsai nods at his colleague. Teeth were sprayed into a sealed glass tube, gas was sprayed and the results were displayed on the monitor.

Jungwoo examined the gas detection process at the tip of the sensor with molecular vision.

The carbon nanotube sensor here. It removes the remaining gas molecules from the sensor with ultraviolet light after detection. There's been an error with the debris that hasn't been removed yet.

In this opinion, the minor discrepancy was measured by manipulating secondary sensors for sensor monitoring.

Finely detectable. But isn't this an unresolved problem?

It's early to insist.

There are many ways Jungwoo can shoot dust particles into the molecular world and simply blow them away, but if he explains the concept to Jun Tsai, he will be treated as a mad chemist.

Jungwoo told me how he had thought about it over lunch.

How about adding a mop to wipe the sensor once, not just with heat?

Mop?

That's the metaphor. You use a sensor once, and then you put in a superabsorbent polymer right after that.

Method of converging at error rate zero. After Jungwoo's troubled answer, Jun Tsai accepted the answer, but he couldn't understand it.

I know the concept, but it will take twice as long to build the customized polymer for this sensor.

"Oh, that. I have a guy who's doing customized research.

Who · · · · · · · · ·.

There she is. Miss Song! Over here.

“Hello!"

The researchers paused for a moment because of a woman who walked into the lab, greeting brightly.

Those who had developed some immunity to the beauty of women while working with Mei, a long and cool beauty, were just surprised to Song Young-young who was armed with noticeable cute.

Song Bo-young pouted her lips as she came to Jungwoo's side.

“What is Miss Song? It's not the '90s. ”

“Usually Miss and Mr. are attached here. Do you speak English? ”

“I can't believe it. ”

“Greetings. This is Joonchai. ”

“Hi!"

Jun Tsai hesitates as a schoolgirl greets her kindly.

Even if you look away, he's my senior.

The sound made the eyes of the sub-difference wider. Jungwoo pointed at the sensor in the glass tube to Song Bo-young.

“Here's what you'll see. ”

“Wow, it looks really complicated. Do you know the mechanical side? ”

“It's not like that. Her period · · · · hmm. because the polymer that you're carrying seems appropriate for this sensor. Talk to Jun Chi and pay more. ”

Song Bo-young nodded broadly and smiled.

“I'll make it worth your while. ”

“I didn't call you for good, I called you because I needed it for this project, and that's a very good misunderstanding. I don't get paid if I'm a cow. ”

“Whatever.”

After introducing Song Bo-young to Joon-Tsai, Jungwoo went straight to the filter team.

Kim was sad as soon as he saw Jungwoo.

“Does this make sense? What kind of team leader teases you to do this all the time? ”

“You heard about the other companies. ”

“They would have developed at least a year. It's only been two months. What, Korean people get used to it so quickly, you have to study it? It's the Chinese market. It's big.”

“Huh? Ha, there's my surrogate. ”

Jungwoo raised his hand to congressman, pretending not to hear Kim Tae-san's grumbling. The House of Representatives rushed in and took a breath while placing the plastic box on the filter team's table.

“Prototype, barely done for testing. ”

“This is that. ”

“Yes, this is the new 9-step filter. ”

Jungwoo opened the box and pulled out a filter the size of the phone.

“Tae-san. Here's the master key to level five. ”

“Jungwoo, you don't do that either. People have to bounce around and do things that don't make sense because they listen to what they're told. ”

“What was that movie? There was a film by a teacher who didn't give me a carrot and whipped me. In a short period of time, students are just · · · · · · ·. ”

“I want to study stability at this age, not pressure. ”

Mei walked in while the facility team installed a new filter in the model house in the central purification system.

We will begin integration measurements immediately at 4 o'clock.

Song Bo-young, who was having an exciting conversation with Joon-Tsai, ran to the side of Jungwoo.

“Whoa, look at her height. ”

“Sister? Have you actually spoken to her? ”

“Now we have to try. There were very few women in the lab, so my personal research came to a dead end. ”

Song Bo-young looks up at one head bigger than her.

“How did it go with Jun Chi? ”

“Yes, I heard you had a tender. We're supposed to deliver it by Monday morning. So I go to work on weekends! ”

It seemed exciting to do more work.

Contaminant Input.

Just before the measurement, Mei looked back at Jungwoo.

Jung Woo smiled boldly and said there was nothing wrong with his face. Somehow, today was still okay.

Prepare to start the fan. One, two, three.

In time to call out the three, the appliance team familiarized themselves with the switch. A harmful substance was placed inside the model house surrounded by semi-circular glass.

Mei coughs with a hand on her mouth, "Cough."

Jungwoo looks at Mei, wondering if she caught sight of something she couldn't say in three places, and finds something between the glass membrane of the semicircle and the table. It was a small piece of wire of 2 mm thickness that fell during the filter change operation.

Huh?

The gap between the pieces of wire that appear to expand into molecular field of view. The particulate matter was spilled out of there.

Mei, standing in front of you, inhales dust through her nose and begins to sigh.

Jungwoo rushes to the table and pulls the piece of wire out with his fingernails.

“There was a gap here. It's going to be a glitch, so please stop running! ”

This shout caused the appliance team to switch rapidly. Jungwoo looks at Mei and asks.

Sir, are you okay?

Inhalation of very small amounts of spilled fine dust. Though it may be less than the amount of fine dust outside that's causing such a commotion, Mei is breathing heavily as if she was hit.

June difference · · · A · · Room · · ·

Mei's agonizing expression stirs as she struggles to make a sound of friendship.

Master!

Jungwoo hugged Mei and shouted to Jun Tsai.

The Team Leader said 'Jun Chi Bag’!

Subdifferences were already after they jumped out of the laboratory. Kim Tae-san approached from behind Jungwoo and supported Mei together.

“Why are you breathing so hard? Wait, Team Leader Yoo, is that asthma? Jungwoo, sit down! ”

Kim Tae-san led Mei to a chair.

Joon-Tsai, who came back with the bag, pulls the inhaler out from inside and bites Mei's mouth. Mei takes in the town and inhales heavily, and begins to find rest.

Jung picked up his cell phone while everyone was standing in shock.

“I'll call an ambulance. ”

“No.”

When Mei shakes her head while speaking Korean, Kim Tae-san, who was supporting her, flinched.

“About 5 minutes · · · will be · · fine. ”

It was awkward in pronunciation, but in the appearance of Mei speaking the correct Korean grammar, Kim Tae-san felt a cool sweat dripping down his back. I understood all the conversations I had so far. Then I felt goosebumps in my forearms because I didn't say anything.

Mei sits with her weight on her arm, leaning against the back of a chair, and her nazi calls out to Jungwoo.

Deputy Chief.

Jungwoo approaches Mei and listens to her voice.

It · · · takes over. Tell us the results · · ·

Shouldn't you be in the hospital?

When rested · · · It's okay. Familiar · · · work. Associate difference · · · · · · · · · office · · · · · ·.

May can't tell if she's breathing at once. Joon-Tsai carried her out of the lab.

Kim Tae-san shakes his head.

“I haven't had an asthma attack in years. She's scary.”

The researcher from the filter team approached Kim Tae-san and asked in a low voice.

“You've heard all the swearing you've been doing. ”

“I'm the only one who cursed! ”

“You've done it the most. ”

Tae-san Kim grumbled and shut up.

In an hour.

Jungwoo was wandering around the office of the sensor team. Kim Tae-san was sitting next to him with a very dark expression, his gaze turned towards Mei's private office.

“What am I supposed to say when I see you? ”

“Just apologize. Then I guess he'll just have to ignore it again. ”

“Oh, I'm embarrassed. ”

Kim Tae-san sighed. When he saw a man who had just come inside, his office door was opened and he stood up.

“Yes, sir. ”

A startling slave ship hurriedly approached them.

“You said Mae had a seizure. Why aren't you at the hospital? ”

“I don't want it. ”

The slave line filled its tongue with this answer. Jungwoo pointed inside and said.

“I'm calling the doctor and checking in. ”

“Dr. Moon? ”

“I was just in the biomedical center today. ”

A slave ship sat in a chair with a worried face. Then I turned my head to Kim Tae-san who was following me and stared at him.

“How did Taesan help you? From what I hear, you were uncooperative. ”

“You're mistaken. I did what I had to do and I grumbled. ”

“He's got a lot of acrobatics in his sights, even if Mae sees him. Why did you come to me after picking sensor patents from China and getting so many scout offers? I'm not here because I believe these center researchers are the best. ”

“Such · · · · · · · · · ·. ”

“If you harm the reputation of the center, you'll see. ”

Kim Tae-san lowered his head and became mute. Slave vessels toured offices that only Chinese researchers were using separately, he said.

“These frustrated people. There are no borders to research. ”

While waiting for Doctor Moon's appointment, the slave ship told me more about Mei.

When I was a chemistry professor at Seoul University, I studied with exchange students at Beijing University. Even an elite past who overcame her troubled childhood.

“Right next to their residential area was a fire power plant. So you don't have asthma? More than half the kids who go to school there lived with respiratory illness. ”

In KG chemistry, Kim Tae-san's expression became even more blurry as she single-handedly devoted a few years to air purification research.

“I was an asshole. ”

“You'd do well to know that, man. Don't piss off the filter team. ”

“It was better when Jungwoo came. ”

“The best in materials science is saying that you're proud of it! ”

Sweet.

The door opens and the door on the stethoscope walks out of your neck.

Jungwoo approached and asked.

“What do you think?”

“I have found rest. I don't think I need to go to the hospital. I just need to rest for a few days. He suffered a seizure by inhaling bad air into the exhaustion. ”

The slave ship lets out a sigh of relief for this sound. Dr. Moon flinches slightly as he sits to the center chair and lowers his head lightly at him.

“Yes, yes. Thank you, Dr. Moon. I hear your compliments every week from Herr Centers. I'm looking forward to it. ”

“That's a compliment.”

Dr. Moon, praised by a highly clever touring slave ship, told Jungwoo.

“I'd like to see you for a moment. ”

“Me?”

“Yes.”

A slave ship that seemed to be about to run into Mei immediately retreats to the sound of this.

As you walk through the door, you see Mei leaning against the couch.

“Okay · · ah. ”

May shakes her hand to ask in English.

Thank you for today. What was the outcome?

From day one, Jung smiled bitterly at Mei's attitude, and told her that she was working with the polymer project team to improve the sensors, and that she had succeeded in air purification to Grade 5.

Amazing, you surpassed the two years I studied in one week.

That became the base. And didn't I tell you that you're not doing research alone? You need to relax and bid.

That's why I have a request.

Mei pulls out an envelope from her bag.

I was supposed to attend, but the air in Seoul isn't good tomorrow either. I don't think I'm gonna be able to make it out of here.

Jung, who received the envelope and opened it, opened his eyes wide. It was an invitation to the Asian Environmental Forum event at a famous hotel downtown. It was an international public event, and it was sealed with the Foreign Minister's seal.

There is no one to go to instead of the deputy chief. You just sit there and come out. I don't care if it's dinner or not.

Invitation from environmental project participants representing KG chemistry. This was also an extension of the work. Jungwoo glances at Mei with a pale complexion and nods.

I will.

The answer reminded me of a weekend pledge.

Maybe · · · · · · · · ·. Is anyone okay with one of these?

Jungwoo came out and picked up his cell phone. I took a deep breath and wrote a letter.

[Mr. Lee... tomorrow... would you like to go to the Pan-Asian Environmental Measures Summit under the United Nations Convention on Climate Change?]

I press Send and close my eyes.
