Ozone process is currently applied in 24 water treatment plants in Korea to control micropollutants and taste & odor compounds. However, one of the chlorine resistant protozoa, cryptosporidium, is not being considered as ozone disinfection performance whereas U.S. is already regulate Cryptosporidium by ozone disinfection. two ozone plants(PH, UH WTP) operation conditions are investigated for disinfection performance comparing Korea disinfection regulation and U.S. regulation. The ozone plants are unable to get Cryptosporidium inactivation credits by Korea disinfection regulation. However, the inactivation credit for Cryptosporidum was increased when the U.S. disinfection regulation was applied. The Korea disinfection credit regulation need revision to practical aspects.

인공지능윤리교육을 위한 AI모델의 활용 실태 연구

노희수,한선관 한국인공지능교육학회 2024 인공지능연구 논문지 Vol.5 No.1

The purpose of this study is to analyze recent previous research related to artificial intelligence ethics education, analyze AI models that are frequently used in the teaching and learning process, and suggest the direction of AI ethics education. First, we collected AI ethics-related research and education cases and analyzed commonly used AI models and services. And, using text mining, we analyzed what keywords teachers use when designing lessons. As a result of the analysis, teachable machines were used the most in class, followed by moral machines, sound models, and image models. In the case of AI models, teachers used image models the most. The results of analyzing important keywords through text mining were in the following order: ‘data’, ‘chatbot’, ‘program’, ‘car’, and ‘autonomous driving’. The most frequently mentioned keywords in ethical concepts related to artificial intelligence were problem, bias, principle, personal information, and responsibility. We hope that the results of this study will be of great help in AI ethics education for elementary school students.

김태민,노희수,김태열,전웅식 한국항해항만학회 2010 한국항해항만학회 학술대회논문집 Vol.2010 No.추계

해양환경에서 장기간 부이(buoy) 관측을 수행할 경우 고정용 앵커에 로프가 감기거나, 부이가 흐름에 의해서 회전을 하면서 부이와 로프가 엉켜서 자료의 수집이 불가능하거나 혹은 장비의 본실이라는 심한 문제가 초래하게 된다. 이러한 기존 부이설치 방법에 따른 문제점을 개선하여 해양자료를 수집할 때 로프의 엉킴을 방지할 수 있는 방안을 도출하였다.

김시원,김선주,노희수 한국농공학회 1986 한국농공학회논문집 Vol.28 No.4

This study was fulfilled by the weighing lysimeter method at the experimental farm of KonKuk University from April to June of 1986 to investgate the amount of evapotranspiration ( ET-lettuec )by the growing periods, evapotranspiration ratio, amount of watering per one time, days of intermission and soil moisture extraction pattern of the crisphead lettuce cultivated in the clay loam soil by different watering points of pFl.7, pF2.O, pF2.7. The results obtained are summar ized as follows : 1.The total evapotranspiration(ETlettuce) of the pFl.7 treatment plot was 358,9mm., 314.9mm in the pF2.O plot and 281.8mm in the pF2.7 plot, therefore the total ETlettuec increased with the difference of 33mm-44mm by the decrease of watering point. 2.The daily maximum ETlettuce by the watering points was 7.66mm, 6:54mm, 5.98mm, respectively in the last ten days of May, and the mean daily ETlettuce during the growing season by the watering points of pFl.7, pF2.O and pF2.7 was 5.44mm(384.5g), 4.77mm(337.2g) and 4.27mm(301.8g), respectively. 3.The evapotranspiration ratio showed maximum value in the middle of May which was the beginning of mid-season stage, and the mean evapotranspiration ratio during the total growing period was 1A7, 1.29, 1.15 by the watering points. 4.The days of watering intermission by the watering points of pFl.7, pF2.O and pF2.7 was 1.0day, 2.9days and 12.Sdays, respectively. 5.The yield of the crisphead lettuce by the watering treatments showed very high significance, and the pF2.O was confirmed as a optimum watering point. 6.The soil moisture extraction pattern(SMEP) of the pF2.0 treatment plot in the initial stage was 85.6% in the 1st and 2nd soil layer and 14.4% in the 3rd and 4th layer, and in the midseason stage, the moisture extraction proportion of the under layer accounted for 34.7%which showed that the root elongated to the lowest soil layer, and there was no difference of the SMEP between the mid-season and late-season stage. 7.The correlation coefficient between the ETlettuce and yield of lettuce by the three watering points was.739, which showed the significance of 5%.

메이크업 제품에 있어서 특히 아이섀도나 블러셔와 같은 포인트 메이크업 제품의 제조시 화사함이나 광택을 부여하기 위하여 사용되는 펄 안료에 대하여 분쇄시간에 따른 입도분포 변화와 결합제로 사용되는 바인더의 영향에 따른 입도분포의 변화에 대하여 검토하였다. 고속 회전형 믹서기를 사용하였으며 레이져 회절·산란법을 이용하여 입도분포를 측정하였다. 평균경 5 ㎛의 펄 안료인 경우 120 s간 분쇄하였을시 4.5 ㎛로 입자경의 변화 폭이 작지만, 45 ㎛인 경우 27 ㎛로 현저히 작아지며 그에 따라 본래의 광택감도 떨어지는 것을 확인할 수 있었다. 바인더의 경우, raw material의 입자사이즈에 따라 분쇄시간과의 상관성을 확인하였으며, 바인더 함량에 따라 입자간의 응집에 의하여 발생하는 분립체의 입도분포의 변화에 대해서도 고찰하였다. For pearl pigments used for splendor or gloss effect of make-up products, especially point make-up products like eye-shadow and blusher, we studied the variation of particle size distribution by the grinding time and by the binder used as a binding agent. In this study, high speed mixer was used and the particle sire distribution was measured by using the light scattering method. In case of pearl pigments, its median diameter of 5 ㎛, the particle size was reduced to 4.6 um when it was ground for 120 s. When it was applied for the pearl pigment of 45 ㎛, the particle size was reduced to 27 ㎛. We confirmed that the latter was reduced more largely and the original gloss was reduced too. For the binder, we studied the correlation between particle size of raw material and grinding time. We also investigated the effects of the binder contents on the variation of particle size distribution of products by aggregation of particles.
