Mathematical Approach on Composition of Nomination Committee for University President Election
Sucheol Yi, Sunyeong Heo 조선대학교 기초과학연구원 2016 조선자연과학논문집 Vol.9 No.1
The university president direct election system in Korea had begun in 1987 as a movement of college democratization in the 1980s after 6.29 Declaration. Since then, many national/private universities had adopted the election system. However, it has posed many problems and it caused a sharp division of opinions between those who approve and disapprove the direct election system. Since 2005, the government has made official of the reformation and/or abolition of the university president direct election system, and has kept pushing for universities to give up the direct election system. Now, only 3 or 4 universities hold on to the system, and many universities have changed into the indirect election system. In the indirect election, a key is the composition of president nomination committee, which confirms the university members’s variety. Many universities adopting the indirect election system have used simple random sampling, like drawing lots, to compose the president nomination committee. However, drawing lots has a problem that it has large possibility of composing a biased committee. This research suggests systematic sampling as an alternative to drawing lots. A numerical analysis was conducted using a data of a university in which the indirect election was implemented recently. The drawing lots gave the biased nomination committee. On the other hand, the systematic sample improves the problem and confirms more the variety of all members.

Driver errors are the main cause of most car accidents. To decrease the accident rate, driver assistance system is necessary to minimize the risk and occurrence of accidents. In this paper, the criterional algorithm for estimating driving state for advanced driver assistance system was employed to avoid the rear end collision. And TTE(Time to enter), TTD(Time to disappear), TTC(Time to collision), TTB(Time to break) and TTT(Time to touch) were calculated by using the criterional algorithm for estimating driving state for ADAS. The effect of applying the criterional algorithm for estimating driving state for ADAS in shown from TTE, TTD, TTC, TTB and TTT to assist actuating timing on the simulation results.
