        최호근(Choi Ho-Keun) 한국제노사이드연구회 2007 제노사이드연구 Vol.2 No.-

        Since the World War II many parts of the German society struggle to come to terms with its own past, but very slowly. The exhibition Vernichtungskrieg. Verbrechen der Wehrmacht 1941 bis 1944 was the very example which shows well the way in which the German society reacted against its own shameful past. Upon the end of the war in 1945, several prominent Wehrmacht generals made a statement that defended the actions against partisans, executions of hostages, and the use of slave laborers as necessary to war effort. The generals contended that the Holocaust was committed by the SS and its partner organizations, and that the Wehrmacht command had been unaware of these actions in the death camps. This statement said that the armed forces had fought honorably and left the impression that the Wehrmacht had not committed war crimes. Although a number of high Wehrmacht officers stood trial for war crimes, the ‘legend’ of the Wehrmacht did not easily perished. The road to come to terms with the past of Wehrmacht was really long and dark. Both German states needed to establish armed forces, and could not do so without trained soldiers and officers that had served in the Wehrmacht. Cold War priorities and taboos about revisiting the most unpleasant aspects of World War II meant that the Wehrmacht’s role in war crimes was not seriously re-examined until the late 1980s. The view of the ‘unblemished’ Wehrmacht was shaken by an exhibition produced by the Hamburg Institute for Social Research titled Wehrmachtausstellung. The popular and controversial traveling exhibition asserted that the Wehrmacht was involved in planning and implementing a war of annihilation against Jews, prisoners of war, and the civilian population. The exhibition of course provoked many criticisms. These led its committee to conclude that the exhibition be reopened in revised form. The exhibition and the debates related to it show well the twisted long-process to overcome the shameful past in German society. Nowadays the past of the Wehrmacht stands in the center of the Vergangenheitsbew ltigung in Germany.

        2-Methylisoborneol(2-MIB)제거를 위한 산화 및 흡착공정의 특성

        최근주,김상구,류동춘,신판세,손인식,오광중 한국환경과학회 2002 한국환경과학회지 Vol.11 No.3

        One of the Musty and earthy smell compounds in raw water is generally attributed to 2-methylisoborneol (2-MIB). It is well known that activated carbon and oxidants such as O_3, ClO_2 are effective ways to control 2-MIB. In isotherm equilibrium experiments, 2-MIB in distilled water was much more adsorbed to the activated carbon(A/C) than raw water containing dissolved organic carbon (DOC). The Freundlich constants(k) of distilled water and raw water were 3.36 and 0.049, and 1/n values were 0.80 and 0.42, respectively. The 2-MIB residual rate were Y = e^(0.55_x)~ e^(-0.54_x) with Ozone(O_3) dose by 5 minutes contact time at the 241 and 353 ng/L initial concentrations. The 2-MIB residual rate were Y = e^(-0.32_X)~ e^(-0.35_X) with Chlorine dioxide(ClO_2) dose by 15 minutes contact time at the 89 and 249 ng/L initial concentrations. 2-MIB was decreased from 1911 ng/L to 569ng/L by post-ozonation(70%removal efficiency) and removal efficiencies of 2-MIB by the following 4 kinds Granular Activated Carbon(GAC) process such as coal base, coconut base, wood base and zeolite+carbon base were 95.8, 89.5, 88.4, and 93.7% respectively.

        한국구강보건사업이 초등학교 아동들의 유치 및 영구치 우식실태에 미치는 영향

        최순례,유영아,조민정,송근배 韓國學校保健學會 2004 韓國學校保健學會誌 Vol.17 No.2

        Purpose : The aim of this study was to evaluate the effects of oral health care programs in a school-based oral health care center among primary schoolchildren. Methods : School-based oral health care programs included fluoride mouth rinsing, pit and fissure sealing for permanent premolars and molars, fluoride gel application and chewing of xylitol candy. All of the programs were carried out by one dental hygienist among 'D' primary schoolchildren in Daegu city under the supervision of a dentist. Baseline dental examinations were completed and preventive care was implemented for 544 children during one year. All of the children visited a school-based oral health care center every three months for a regular check-up. The final oral examination was conducted from March 15 to April 1, 2004. The data analysis data was made on the basis of SAS 8.01. Mean differences between 2003 and 2004 data were compared by paired t-test. Corresponding p-values were considered significant at values less than 0.05. Results : The DMF rate and DFT index were reduced to 8.0% and 8.4% during one year respectively, but there were no statistically significant differences. The DMF rate was significantly reduced (16.3%) after a one year program of school-based oral health care practice. The DMFT(Decay Missing Filling Tooth) index was also reduced compared to 2003 throughout the entire grade. Conclusion : School-based oral health care programs can reduce the prevalence of dental caries prevalence among schoolchildren during one year. This program also improved the oral health capacity of schoolchildren. It is recommend that the school-based oral health care program should be extended to every primary school in Korea

        광센서 조광제어시스템에서의 광센서 최적 방향성과 위치에 관한 평가 연구

        최안섭,정근영 대한건축학회 2003 대한건축학회논문집 Vol.19 No.10

        The purpose of this simulation study was to improve the performance of daylight responsive dimming systems. This simulation study was to analyze the followings. ⅰ) correlation between workplane illuminance and photosensor signal ⅱ) comparison between closed loop proportional and open loop proportional control algorithms in the daylight responssive dimming system. This study used DayDim as a simulation software and four different spatial characteristics of photosensors. Each photosensor has different spatial distributions in the existing photosensor, 0 degree, 30 degree, and 60 degree from nadir. Parameters such as sky condition, seasonal changes, azimuth, photosensor location, and different spatial distribution were considered. The results showed proper photosensor position and spatial distrubution determined by the various parameters.

        崔洪植,邊根周,李相旻 연세대학교 산업기술연구소 1984 논문집 Vol.16 No.2

        A mathematical model is formulated for the minimum cost design of reinforced concrete earth structures. The design variables are selected to be the depth and steel ratio in the retaining wall, and the depth, steel ratio and footing sizes in the isolated column footings. An elastic analysis is performed and resulting designs are based on both the ultimate strength theory and the elastic theory of concrete design. Constraint requirements are imposed to insure structural strength and side constraints. The resulting mathematical model is a nonlinear constrained optimization problem. The modified Lagrange Multiplier method is suggested as a satisfactory algorithm for the optimum design of the R.C. earth structures.
