宋泳柱,權寧立,吳南起,高福來,黃昌周,朴建鎬 韓國作物學會 1992 Korean journal of crop science Vol.37 No.1

벼 콤바인 수확답에서 탈립된 종자의 월동중 활성검정 및 품종별 탈립량에 따른 이형주 발생정도와 양상을 검토, 벼 종자 순도유지에 관한 기초자료로 활용코저 하였던바 아래와 같은 결과를 얻었다. 1. 탈립종자의 시기별 발아율은 일반형, 통일형 모두 경과시기가 길어질수록 낮아지는 경향이었으며, 발아세의 경시적 변화도 같은 경향을 보였다. 2. 조사시기에 따른 종자 단백질의 전기영동적 차이에 있어서 팔공벼, 삼강벼 공히 단백질 Band에 농·담의 차이가 있었다. 3. 생태형별 이형주 발생율은 일반형 품종이 통일형 품종에 비하여 이형주는 대비품종에 비해 초장, 주당경수, 엽장, 절간장, 수장 및 수당립수 등의 형질이 저하되는 경향이었다. 또한 1차 지경보다는 2차지경에서 저하율이 컸으며 수당 영화수에 대한 상관정도는 2차지경이 높았다. 4. 이형주 종자의 발아능력은 대비품종에 비해 대차가 없었고 종자수량에 있어서 일반형 품종이 평균 5.1kg /10a, 통일형 품종이 평균 0.9kg /10a 였으며, 생태형별 대비품종에 대한 혼입비율은 일반형 품종이 0.7%, 통일형 품종이 0.1% 정도였다. Germinability, electrophoretic variation of protein of shattered seeds during overwintering and characteristic of main agronomic traits of off-type rice plant occurring in paddy field harvested by combine were investigated. Germinability of shattered seed decreased as time goes in paddy field in both Japonica and Tongil type varieties. Electrophoretic protein bands become more and more light as time goes. Occurrence of off-type rice plant was higher in Japonica varieties than in Tongil type varieties. Off-type rice plant was shorter in plant height, leaf length, tiller number per hill, internode length, panicle length and spike let number per panicle. Germinability of seeds of off-type rice plant as not significantly different compared to the control variety. Yield of off-type plants of Japonica varieties was on average 5.1kg / 10a and that of Tongil type varieties was on average 0.9kg /10a. Mixing ratio to the control variety was about 0.7% in Japonica varieties and that of Tongil type varieties was about 0.1%.

Development Strategy of Orbit Determination System for Korea’s Lunar Mission: Lessons from ESA, JAXA, ISRO and CNSA’s Experiences

송영주,안상일,심은섭 한국우주과학회 2014 Journal of Astronomy and Space Sciences Vol.31 No.3

In this paper, a brief but essential development strategy for the lunar orbit determination system is discussed to preparefor the future Korea’s lunar missions. Prior to the discussion of this preliminary development strategy, technical modelsof foreign agencies for the lunar orbit determination system, tracking networks to measure the orbit, and collaborativeefforts to verify system performance are reviewed in detail with a short summary of their lunar mission history. Coveredforeign agencies are European Space Agency, Japan Aerospace Exploration Agency, Indian Space Research Organizationand China National Space Administration. Based on the lessons from their experiences, the preliminary developmentstrategy for Korea’s future lunar orbit determination system is discussed with regard to the core technical issues of dynamicmodeling, numerical integration, measurement modeling, estimation method, measurement system as well as appropriatedata formatting for the interoperability among foreign agencies. Although only the preliminary development strategy hasbeen discussed through this work, the proposed strategy will aid the Korean astronautical society while on the developmentphase of the future Korea’s own lunar orbit determination system. Also, it is expected that further detailed systemrequirements or technical development strategies could be designed or established based on the current discussions.

벼 무논 골 뿌림재배 파종방법 및 담수시기

宋泳柱,權錫周,黃昌周 韓國作物學會 1994 Korean journal of crop science Vol.39 No.3

최근 담수직파 재배양식중 승용형 골뿌림 파종기를 이용하여 파종골을 작성, 이와 동시에 종자를 파종하고, 생육기간동안 골이 자연적으로 매몰됨으로서 도체가 지지력을 가져 직파재배시 단점중의 하나인 도복을 경감시킬 수 있다는데 근거를 두고 시험연구가 급속히 진행되고 있는 무논 골 뿌림 재배법 확립의 일환으로, 먼저 초기 입묘와 밀접한 관계가 있는 파종전 토양굳힘정도, 파종 골 깊이, 그리고 파종후 담수시기 구명을 위하여 시험한 결과는 아래와 같다. 1. 파종전 토양의 굳힘정도는 파종시 종자의 매몰정도, 파종후 담수시 종자 부유상태 및 생육기간동안 골 매몰로 인한 줄기매몰심도등을 고려할때 경운정지후 낙수하여 3일정도 굳힌상태 즉, 115g의 원추관입심이 6~7cm정도인 상태가 적절하였다. 2. 파종골 깊이별 최고 분얼기에 조사한 토양매몰정도는 4~6cm심도의 경우 3~4cm정도의 토양매몰이 이루어졌으며, 입묘율은 골 깊이가 깊을수록 떨어지는 경향이었다. 표면조파(0cm)의 경우 부묘가 발생되었으며, 골 깊이별 뿌리 분포비율은 파종심도가 낮을수록 표층의 뿌리 분포 비율이 높고, 도복정도 역시 8 정도로 매우 높아서, 줄기 매몰심도 및 도복정도 그리고 수량성으로 볼때 파종골 깊이는 4cm정도가 적당하였다. 3. 파종후 담수시기가 늦어질수록 입묘율이 떨어졌으며, m2 당수수의 확보 역시 적어서 담수시기는 파종직후 담수가 바람직 하였다. This experiment was conducted to investigate of soil hardening degree before sowing, furrow depth at sowing and flooding time after sowing at furrowing in flooded rice paddy field that many people have an interest in as direct sowing method most recently. As hardening period was increased, the percentage of seedling stand and seed floating at flooding were increased slightly, while buried depth of stem at maximum tillering stage and cone penetration depth were decreased, respectively. Therefore, optimum degree of soil hardening was about 3 days after draining, at this time, cone penetration degree was about 6~7cm. According to furrow depth was more and more deep, buried depth of stem was increased gradually, but percentage of seedling stand was decreased considerbly. Also, root distribution ratio on surpace horizon and lodging degree were increased gradually according to furrow depth become more and more shallow. As flooding time after sowing was late, percentage of seedling stand and panicle number per m2 were decreased slightly. These results apparently indicated that sowing after 3 days hardening when cone penetration degree was 6~7cm, furrow depth 3~4cm degree and flooding time just after sowing the best method to good establish of seedling stand.

Impact of an Antimicrobial Stewardship Program on Unnecessary Double Anaerobic Coverage Prescription

송영주,김문석,허새미,이정화,이윤석,송경호,김의석,김홍빈 대한감염학회 2015 Infection and Chemotherapy Vol.47 No.2

Background: Co-administration of two or more antimicrobials with anti-anaerobic activity is not recommended except in certain circumstances. We therefore conducted an intervention to reduce unnecessary double anaerobic coverage (DAC) prescription. Materials and Methods: The intervention consisted of education using an institutional intranet and prospective audits and feedback provided through collaboration between a pharmacist and an infectious diseases physician in Seoul National University Bundang Hospital, a tertiary hospital in Seongnam, Republic of Korea, in 2013. The study period was 1 year which contained 6 months of pre-intervention period and 6 months of intervention period. To estimate the overall effect of the intervention, we compared the monthly number of patients receiving unnecessary DAC for more than 3 days and the proportion of patients receiving unnecessary DAC for more than 3 days among all patients receiving DAC. Results: The average monthly number of patients receiving unnecessary DAC for more than 3 days after screening decreased by 73.9% in the intervention period from 26.8 to 7.0. Wilcoxon rank sum test revealed there was a significant statistical difference in the monthly number of patients receiving unnecessary DAC for more than 3 days (P = 0.005). The proportion of patients receiving unnecessary DAC for more than 3 days after screening among all patients identified as receiving necessary or unnecessary DAC also decreased by 67.8% in the intervention period from 42.3% to 13.6% (P < 0.001). Conclusion: The multidisciplinary antimicrobial stewardship program with combined methods reduced unnecessary DAC prescription successfully.

Development of Precise Lunar Orbit Propagator and Lunar Polar Orbiter’s Lifetime Analysis

송영주,박상영,김해동,심은섭 한국우주과학회 2010 Journal of Astronomy and Space Sciences Vol.27 No.2

To prepare for a Korean lunar orbiter mission, a precise lunar orbit propagator; Yonsei precise lunar orbit propagator (YSPLOP) is developed. In the propagator, accelerations due to the Moon’s non-spherical gravity, the point masses of the Earth, Moon, Sun, Mars, Jupiter and also, solar radiation pressures can be included. The developed propagator’s performance is validated and propagation errors between YSPOLP and STK/Astrogator are found to have about maximum 4-m, in along-track direction during 30 days (Earth’s time) of propagation. Also, it is found that the lifetime of a lunar polar orbiter is strongly affected by the different degrees and orders of the lunar gravity model, by a third body’s gravitational attractions (especially the Earth), and by the different orbital inclinations. The reliable lifetime of circular lunar polar orbiter at about 100 km altitude is estimated to have about 160 days (Earth’s time). However, to estimate the reasonable lifetime of circular lunar polar orbiter at about 100 km altitude, it is strongly recommended to consider at least 50 × 50 degrees and orders of the lunar gravity field. The results povided in this paper are expected to make further progress in the design fields of Korea’s lunar orbiter missions.
