About Workshop

천문연구원에서 약 34년 동안 재직하며 14m 전파망원경 및 한국우주전파관측망(KVN)의 건설, 초창기 운영과 관측연구 등에 많은 활동을 해오셨고 지금도 하고 계신 조세형 박사님께서 2018년 2월에 공식적으로 은퇴를 하시게 되었습니다. 이번 공식적인 은퇴를 맞아 천문연구원에선 이를 기념코자 "Star forming regions and evolved stars seen by TRAO & KVN"이라는 주제로 작은 워크샵을 준비하였습니다. 이번 11월 30일-12월 1일 이틀간에 걸쳐 대전의 천문연구원 본원에서 열릴예정인 이 워크샵에 바쁘시더라도 참석하시어 뜻깊은 이 자리를 빛내 주시기 바랍니다.

Dr. Se-Hyung Cho is going to officially retire from KASI on February 2018 after his 34 years devotion to KASI including vigorous research activities. In honor of his retirement, we are going to have a workshop titled "Star forming regions and evolved stars seen by TRAO & KVN" for two days of November 30th and December 1st at KASI, Daejeon.

It will be our pleasure if you attend this workshop and celebrate Dr. Cho for his honorable retirement together. Most of the talks of this workshop will be given by invitation, but we still have some limited slots for the contributed talks and also a poster session. The presentation of the talk could be for the subject which you are working on now, or a review which you think proper. You may or may not include something related to Dr. Cho in your presentation.
We expect your active contribution and participation for the success of this workshop.

Thank you very much and see you in the workshop at the end of this November.

With best regards,
Young Chol Minh and Youngjoo Yun
on behalf of the organizing committee of this workshop

Immigration

At the Incheon Airport in Korea (ICN), flights from several airlines often arrive at nearly the same time, making it easier to get to immigration quickly. If you take a Korean airline, you will likely arrive at the main terminal. Otherwise, on arrival at ICN, you will proceed along a series of corridors and down the stairs to board a train to the main terminal (trains run every 5 minutes). The quickest way is to board at the third set of train doors from the right; you will exit on the same side you entered. When the train arrives at the main terminal, you can run upstairs to immigration, as it can be slow if the lines are long. Try the rightmost line for foreign passports, because they often open another line further to the right, so you can dash to the new line; in addition, if there is no line at the Korean citizens’ lane, agents will sometimes bring you there from the rightmost foreign lane.

Luggage and Customs

After immigration, there are boards giving your luggage carousel number. Go downstairs, take a free cart (push down on the handle to move it), collect your luggage, and walk through customs and out (slightly left) into the terminal lobby. It is better not to change money at the booths; instead, use your bank card at an ATM if necessary. Along the far wall by terminal exit 9 there is a booth labeled "Airport Limousine bus." Say you are going to "Daejeon" (day-jun); the ticket will cost 23,100 won. Then walk to the left outside along the terminal until you get to bus stop 9D by exit 9. There is also a bus ticket office outside if the one inside is crowded. The bus leaves every 20–30 minutes or so. Unless you have a lot of luggage, you can bring it on the bus with you. If you hand in your luggage to be placed underneath the bus, you will get a claim ticket; show this to the driver when you exit so that he or she will retrieve your luggage for you.

Using The Bus to KASI

The bus takes 2.5–3 hours to get to Daejeon. There will usually be a 15-minute stop at a highway rest area on the way. After the bus exits the highway through the toll gate at Daejeon, it will be only 5 minutes until your stop. The bus will go along a tree-lined street with many research institutes; KASI will be on your left. You will pass it, and then the road will curve around and come to a Y intersection. Your stop is immediately after the bus turns right at the intersection. Walk back along the bus route for 15 minutes until you reach KASI (now on your right). If you have too much luggage to walk, take the bus one stop further to the Government Complex. There you can get a taxi to take you to KASI (roughly 10 minutes, 6000 won). If you are going to your hotel downtown, take a taxi from the Government Complex stop.

Alternate travel, express train (KTX)

If the buses sell out, or you just like trains and do not have much luggage, you can take trains from Incheon Airport to Daejeon. It takes about the same amount of time but requires more transfers. Follow the airport signs for ARex trains. You can buy a ticket all the way from the airport to Daejeon via Seoul Station (in which case they'll ticket you on a slightly later train to Daejeon to make sure you catch it), or buy a ticket to Seoul Station and then buy a ticket there to Daejeon on the very next train; it doesn't make much difference. I recommend that you use the local, not the express, ARex train to Seoul Station because it takes only 10 minutes longer but runs more frequently, so you'll probably arrive earlier (the express is more luxurious though). Seoul Station is the final stop; the local and express trains take 53 or 43 minutes and cost about 4000 or 8000 won, respectively. At Seoul Station, follow the signs upstairs to KTX, the express long-distance trains. If you already have your ticket, just go to the platform indicated; otherwise, buy your ticket after looking at the departure board to find the next train to Daejeon (any KTX heading to Busan will stop in Daejeon). The KTX takes 1 hour to reach Daejeon. At Daejeon Station, go upstairs and cross to the main area, and then go downstairs to the main exit. Follow the signs to the taxi rank. A taxi should take 20–30 minutes and cost ~11,000 won.

Taxi from Daejeon Government Complex or Daejeon Station to KASI

Taxi drivers will not recognize "KASI"; instead, say Chun-mun Yun-gu-wun. It is best to print out the KASI main web page or visitor guide so that you can show the driver the Korean characters.
