Week 5 -- Flowcharts and museums

1. (What I learned about Korea)

On Monday I went back to the Immigration Office and picked up my updated Visa and my alien card. So now I know how to do that, and I know what the alien card looks like. It's nice having an ID that's small enough to fit in my wallet again.

This past Saturday I went to the Ungno Lee Museum and the Daejeon Municipal Museum of Art. Both were art museums. The Ungno Lee Museum had more traditional paintings and drawings, while the DMMA had mostly modern art. I enjoyed both of them and learned some things about Korean artwork.

I also saw the Hanbat Arboretum, basically a small garden area. It was relaxing to walk around and explore. I wasn't aware that there were natural areas like that right in the middle of the city (it's right behind the two art museums I went to, themselves only twenty or so minutes from Nuri Hall on foot), so now I know and I can seek out more of them in the future.

Finally, on the same journey, I stumbled upon the Natural Heritage Museum. It's a very small museum that chronicles the animals of Korea. A guide showed me around and I learned about the various rare or endangered species native to Korea. 

I went to see the KAIST orchestra on Friday night. It sounded great. For the first half they did classical music, and for the second they played more popular movie music (like a collection of excerpts from Disney pieces, and a collection of John Williams excerpts, including several Star Wars pieces and the Jaws theme). They had a guy wearing a shark costume come out and run around the front of the audience during the Jaws bit, which was fun to see. The music sounded great as well. And then there was the fun bit at the end, where the conductor let the audience keep time (by clapping) during the last piece, the 1812 Overture. So overall, I learned that the KAIST orchestra is very entertaining.

During the week, the school fair happened, and several of the international student groups put together a food fair, where they set up booths and served traditional foods from their various countries. I had some very good curry from the Indian booth, and something very much like a cheesesteak from the Chile booth. It was great, and I learned that KAIST does events like this, and that it's a good idea to go to them.

2. (Project status)

I completed most of the HUBO project documentation this week, including making the flowcharts and describing all the shared memory variables. All that remains is to tidy up the flowcharts and finish describing the variables whose scope is just the HUBO project. After this, I'll be doing the same thing for the khr3win project. The two work together in order to run the robot.

Also, the ICAHRR paper was accepted! So I'll be working on revising that in the coming weeks, as well as working on a new paper for another conference that will take place in Daejeon this August.

4. (What I learned about myself)

I learned that I enjoy the art in the Ungno Lee Museum and the DMMA, and that I like garden areas such as the Hanbat Arboretum.

5. (New people I met)

I didn't meet anyone new this week.

Week 4 -- Gyejoksan and code


Week four ended today. It went pretty well.


1. (What I learned about Korea)

On Sunday I went to the Currency Museum, which is right by KAIST. It had exhibits with the various types of currency Korea had used since before recorded history up to the present. It was very interesting.  There was also a section on medals and other special awards, so I got to see some military medals up close.

I also visited the Biosphere, which is near Expo Park. So I learned a little bit about the local trees, which was interesting.

On Wednesday a student group at KAIST performed some traditional Korean music. It was very good. I found out what sorts of instruments are used for Korean classical music, and I got to listen to some of it in a relaxing setting. The music was very good.

Rather than exploring Lake Daecheonghosu as I'd planned last week, I went to Gyejoksan mountain instead. I hiked high enough to see some beautiful vistas. I managed to get to where they had one of the old fortress walls, where a bunch of people were having fun and talking. It was a rewarding walk. I stumbled on an exercise/play area that I think was Jangdong forest as well. Unfortunately, I wasn't able to get to several of the more notable sights (such as Dongchundang), so a return trip just may be in order. 

2. (Project status)

My next goal is to document the HUBO code. This week I went through the HUBO project function-by-function to analyze them all and determine what they did, and now I'm mapping out the relations between functions.

4. (What I learned about myself)

I learned that I enjoy traditional Korean music. Also, when I had some cab trouble getting back from the mountain, I learned that I can recover from unexpected difficulties like that.

5. (New people I met)

While at a restaurant before going to Gyejoksan, I found myself sitting next to a Mr. Kim. We talked a little, and I mentioned that I was a student from America who was studying at KAIST for the moment. He seemed interested and we talked about that for a little bit. He helped me fill in a couple gaps in the guidebooks KAIST gave us (the exact dates of a couple festivals that were just mentioned as being 'sometime in April.') A very nice guy.

Week 3 -- CAN completion and Mt. Sikjangsan


Another good -- and productive -- week.

1. (What I learned about Korea)

I went up to Mt. Sikjangsan this week, and I saw some very nice trails and did some hiking. I ended up going about 3 km into the woods. It was a lot of fun. I found out later that this was known as one of the 8 most famous attractions in the city. I also found the temple section of the mountains, and I explored Gosansa and Sikjangsan temples. It was a good place to get photographs.

I also went and applied for my alien card (as well as to upgrade my visa to multiple entry, in case I later want to visit another country in East Asia during my stay here). So I learned how to do that and how to get to the Immigration Center.

Finally, as it was my birthday on Wednesday, Sean helped us get a cake, and I learned where to go to get cakes in Daejeon.

2. (Project status)

I extracted the CAN from the rest of the HUBO code early this week, and used the documentation to write a program that would test the CAN bus. Clayton wrote drivers for the CAN code, and when this was done, we sat down and debugged the system. It now works -- we can send and receive from the CAN bus.

4. (What I learned about myself)

I learned that I can hike through the woods pretty well. I also learned that I really like these '8 Daejeon attractions,' and so I'll try to go visit more of them in the coming weeks (next up, I think, is Lake Daecheonghosu. Expo Park, literally next door to Nuri Hall, is on the list as well, but that one's so close that I want to see some of the further ones first).

5. (New people I met)

I didn't meet any new people this week.

6. (Current events)

North Korea claims to have launched a missile a few days ago. America is denying this claim. It's a little bit strange to think that we're relatively close to a hostile country, but at the same time it doesn't feel like we're in imminent danger or anything. Even setting aside whether the missile got into orbit or not, it just seems hard to imagine an actual attack on the city. Some of it may be due to language disconnect, though -- it's hard for me to tell if average people in the street are nervous about it, since I have trouble understanding them.

Week 2 -- Settled in


Week 2 in Daejeon ends tonight. It was a pretty good week. Things went very well.

1. (What I learned about Korea)

The KAIST auditorium has biweekly concerts, it seems. I went to one this Friday. There was a cellist and a pianist, and they went through some classical pieces. It was really good music and quite enjoyable; they even played an encore at the end, a Chopin prelude, that I know well, and that was a fun surprise.

I also went out for my first Korean barbecue meal since arriving, and was reacquainted with all of the delicious side dishes that come with it. Some of the sides were actually new to me; I hadn't had them when I had barbecue in Korea in November.  One was a hard-boiled egg in soy sauce, another was squid, and a third was a sort of sweet-potato kind of food. It was very fun.

Apparently I was holding my chopsticks incorrectly. I was holding them so that they crossed; the guys in the KAIST lab showed me how to hold them so that they don't cross. This is the more acceptable way to do it. So I guess I'll practice using the new way.

Finally, the KAIST guys and I went to lunch on Friday at a Chinese place. Like the first night we came, we got a big sweet & sour pork platter before the main course of noodles or rice. I suppose it's traditional that Korean Chinese restaurant do this. As I generally enjoy these pork dishes, I think I like this custom.

2. (Project status)

I went through the CAN bus code and made extensive notes on what all the functions do, what variables they manipulate, where information is actually written to the bus, etc. Clayton also asked me to make some flow charts showing the operation of the more important functions.

I also read up some more on RTX.

It looks like in the coming week I'll begin studying how to surgically extract the CAN bus from the rest of the HUBO system. I may also (if things work out) begin working on programming my own version of a CAN bus.

At KAIST, a part of the path I take to go from the lab to the piano that I practice on:




4. (What I'm learning about myself)

I spent a lot of time this week traveling without Clayton, and so learned that I'm able to get around Korea fine on my own. Among other things, I ate at several restaurants, hiked some more, and went through Daejeon's downtown area. 

5. (New people I met)

In the dorm I met two students named Baat and Lan. The former was from Pakistan, the latter from Vietnam. I talked to Baat for a while, we discussed the city environment (he was from an urban city near the India/Pakistan border, while I was originally from the Chicago suburbs but moved to Philly) and what we thought of the city. It was a fun time.
