메탄/공기 예혼합화염에서 CARS를 이용한 CO 농도 및 온도측정과 수치해석 결과의 비교
강경태,정석호,박승남 대한기계학회 1995 대한기계학회논문집 Vol.19 No.5
Recently developed technique of measuring minor species concentration by using the modulation dip in broadband CARS has been applied to the flame structure study of methane/air premixed flames in a counterflow. This method used the modulation dip from the cold band CO Q-branch resonant signal superimposed on the nonresonant background. The measured CO concentration profile in a symmetric and unsymmetric methane/air premixed flames together with the velocity and temperature by using LDV and CARS have been compared with the numerical results adopting detailed chemistry modeling. The results show that there is a satisfactory agreement between the experimental data and numerical results for velocities, temperatures and CO concentrations. And the modulation dip technique of measuring minor species, such as CO is a viable tool for a quantitative measurement in a flame.
16대 국회의원 선거: 시민연대의 낙천운동이 유권자 정당선택에 미친 효과

The Citizens' Alliance for 2000 General Elections (CAGE) issued its 86 blacklisted candidates before the election because these candidates were involved in some sort of corruption, irregularities, regional antagonism, election law violations and etc. CAGE staged "defeat movement" for these politicians in an effort to help achieve reform in politics. This is a new phenomenon because until now the nominating of party candidates and the helping of arty candidates to be elected was considered to be under the domain of the party's privileges and obligations. In the 2000 General Election about half of those blacklisted candidates were not elected. This may mean the defeat movement of many civic groups including CAGE was successful. Nonetheless among 22 candidates who were vigorously targeted as ones to reject, 20 candidates ranked second choice candidates after the ballot were counted and seven candidates were elected. Although successful, civic groups rejection campaign need more time and efforts, and organized strategy to make Korean politics cleaner.
