이춘우,백성범 한국국제농업개발학회 2002 韓國國際農業開發學會誌 Vol.14 No.2

일본의 맥류 생산, 연구, 보급, 가공 및 유통에 대한 정책의 전개 방향을 설정한 신 맥류정책이 발표되었으며 이를 해설한 日本의 麥政策 이라는 책이 출간되었다. 이 책에는 향후 일본의 맥류 생산, 연구, 보급, 가공 및 유통에 대한 정책 설명과 정부의 대책이 해설하고 있다. 이 책이 우리나라의 맥류정책 수립에 참고자료로 활용될 수 있도록 요약하여 소개한다. 1. 생산자, 수요자 및 정부가 각자가 신 맥류정책에 부합한 생산비 절감을 위한 종합적인 노력하고, 문제점은 장기적인 시간을 가지고 해결을 모색한다. 2. 국내산 맥류는 민간유통에 맡기고, 생산자와 실수요자가 품질평가를 반영하여 직접 인수체계를 만들고 양질의 맥류생산 계획을 세운다. 3. 연구개발의 충실 및 강화로는 생산자, 실수요자의 의견을 품종개발에 반영하기 위하여 개발단계부터 생산자와 실수요자의 평가를 반영할 수 있는 새로운 체제를 설정한다. 4. 외국산 맥류는 국가무역에 의한 정부가 계획적으로 수입 및 효율적인 운영을 도모한다. 5. 사료용 맥류는 증산제도는 대체사료의 개발, 보급, 각종기업대책 등의 추진하여 2002년까지 폐지하고 특정맥류를 SBS(매매동시입찰)방식으로 단계적으로 도입한다. Japans agricultural situation is similar to Korea where many food crops are imported and the sector is heavily protected. The Ministry of Agriculture, Forestry and Fisheries in Japan announced a new policy to develop the wheat and barley sub-sectors. This policy aims to increase attention given to the cultivation, research, extension, and dissemination of technologies for these crops. The basic strategy is to transfer the management and control of wheat and barley from the government to the private sector. The production of wheat in Japan does not meet its demand because local wheat does not have good quality and price. This is one of the reasons why milling companies do not buy Japanese wheat. This study was conducted to look into this new policy and compare it with the developments in the Korean wheat and barley sub-sectors.

벼 이앙기를 이용한 보리 어린모 이식에 관한 연구

이춘우,백성범,손영구 한국국제농업개발학회 2004 韓國國際農業開發學會誌 Vol.16 No.1

보리 파종 시기에 잦은 강우로 인하여 토양이 과습하여 보리 파종기계의 정상적인 작동이 어려워 파종을 하지 못하는 경우가 많이 있다. 토양이 과습한 경우에도 보리 파종을 하기 위하여 벼 이식기를 이용하여 보리 어린모 이식 가능성을 검토하기 위하여 2002년에는 작물시험장 수원시험포에서 시험한 결과는 아래와 같다. 가. 육묘일수는 3~6일이 좋았고 9일은 너무 자라 기계이식이 잘되지 않았다. 나. 이식율은 높이기 위하여 이식 전 경운하는 것이 좋았으나 월동율이 낮아지는 단점이 있었다. 다. 벼 이앙기를 사용하여 이식하므로 보리는 식물체가 연약하며 보리 어린모가 절단되고, 결주가 발생하는 문제점이 있었다. 라. 이식시 물이 없으므로 이앙기가 가라 앉지 않으므로 이식심도가 낮아져 어린 모의 활착율이 낮고 월동율이 낮았다. 마. 이식시 이식율이 낮고 월동율이 낮아 수수확보가 어려워 수량성이 낮았다. 바. 어린묘 육묘의 가능성을 검토하였으나 위에서와 같은 여러가지 문제점으로 인하여 보리 어린모 이식은 가능성은 낮은 것으로 사료되었다. Heavy rain during the seeding season of barley, poses a lot of problems such as wet soil stuck to the barley seeder making it difficult to use the machine, The cultivation area of barley is dependent on the weather conditions during the seeding time. Usually, during the rainy weather, the area of cultivation is decreased. Since the soil moisture is high during the rainy weather, the ordinary seeding method does not work efficiently, thus, there is a need for a new seeding method. This study was conducted to examine the possibility of using a rice transplanter in transplanting barley seedlings. Before the seedling was transplanted, plowing than non-plowing was increased to improve the rate of transplanting success. The barley seedling was first cut and set in shallow depth using the rice transplanter. To ensure success in transplanting, the wintering rate was decreased. These factors however reduced the number of panicle and yield. The study showed that using the rice-seedling box for barley is possible. However, transplanting the infant barley using the rice transplanter is impossible due to low transplanting rate and wintering.

보리 춘파재배 적응성 품종의 특성 및 선발

이춘우,구본철,백성범,손영구,김홍식 한국국제농업개발학회 2002 韓國國際農業開發學會誌 Vol.14 No.1

보리 품종 중 춘파에 적응하는 품종을 선발하기 위하여 올보리 등 16품종을 시험한 결과를 요약하면 다음과 같다. 가. 천립중과 설립량과는 상관관계가 있어 천립중이 무거울수록 10a당 설립이 적고 수량은 많아지는 경향이었다. 춘파 재배는 생육기간이 짧고 고온하에 등숙이 이루어지므로 천립중이 가벼워지는데 대립종이 소립중에 비하여 설립이 적었다. 나. 수량은 맥종간에는 쌀보리가 겉보리나 맥주보리에 비하여 적었고, 또한 년차나 품종간 변이도 컸다. 다. 쌀보리 품종들은 겉보리에 비하여 간장이 짧고, 설립이 많아 수량이 적었다. 라. 춘파재배용으로는 천립중, 설립량, 간장, 성숙기, 수량 등을 고려할 때 올보리와 사천6호가 가장 안정성이 있는 품종으로 판단되었다. This study was conducted to select varieties for spring sowing in barley. The accumulated and the average temperatures affected the 1,000-grain weight and unmatured grain yield. There was a negative correlation between 1,000-grain weight and the yield of unmatured grain. The 1,000-grain weight became lighter because of short growth period and maturing in high temperature under spring sowing condition. Compare with the covered and two-row barley, the grain was lower than naked barley. Among 16 barley varieties. "Olbori", "Sacheon6" were well adapted to spring sowing condition.

Background: There is insufficient data on the benefits of empiric antibiotic combinations for hospital-acquired pneumonia (HAP). We aimed to investigate whether empiric antipseudomonal combination therapy with fluoroquinolones decreases mortality in patients with HAP. Methods: This multicenter, retrospective cohort study included adult patients admitted to 16 tertiary and general hospitals in Korea between January 1 and December 31, 2019. Patients with risk factors for combination therapy were divided into anti-pseudomonal non-carbapenem β-lactam monotherapy and fluoroquinolone combination therapy groups. Primary outcome was 30-day mortality. Propensity score matching (PSM) was used to reduce selection bias. Results: In total, 631 patients with HAP were enrolled. Monotherapy was prescribed in 54.7% (n = 345) of the patients, and combination therapy was prescribed in 45.3% (n = 286). There was no significant difference in 30-day mortality between the two groups (16.8% vs. 18.2%, P = 0.729) or even after the PSM (17.5% vs. 18.2%, P = 0.913). After the PSM, adjusted hazard ratio for 30-day mortality from the combination therapy was 1.646 (95% confidence interval, 0.782–3.461; P = 0.189) in the Cox proportional hazards model. Moreover, there was no significant difference in the appropriateness of initial empiric antibiotics between the two groups (55.0% vs. 56.8%, P = 0.898). The proportion of multidrug-resistant (MDR) pathogens was high in both groups. Conclusion: Empiric anti-pseudomonal fluoroquinolone combination therapy showed no survival benefit compared to β-lactam monotherapy in patients with HAP. Caution is needed regarding the routine combination of fluoroquinolones in the empiric treatment of HAP patients with a high risk of MDR.

동남아시아 주요 옥수수 생산국인 인도네시아의 옥수수 생산과 생산성 제한 요인에 대하여 조사·분석한 결과는 다음과같다. 1. 인도네시아는 북위 5°에서 남위 10°사이에 위치하여 연중 열대성 기후를 보이며 건기와 우기의 구별이 뚜렷하다. 2. 옥수수 재배면적은 약 4,000천ha 정도이며 생산량은 2009년 이후로 17,000천톤 이상을 유지하고 있다. 그 가운데 수확면적과 생산량의 약 50%를 Jawa섬이 차지하고 있다. 2014년 단위 면적당 생산성은 4.95ton/ha로 1980년대에 비하여 약 3배 증가하였으나 지역적으로는 2.5 ~ 7.32ton/ha의 변이를 보여 지역 간 차이가 심하다. 3. 생물적 생산성 제한요인은 downy mildew (Peronosclerospora),maydis leaf blights (Helminthosporium spp.), leaf spots (Curvularia spp.), rusts (Puccinia polysora), stalkand ear rots (Fusarium spp., Diplodia spp.), banded leafand sheath blight (BLSB, Rhizoctonia solani) 등의 병과 바구미(Sitophilus spp.), shoot flies (Atherigona spp.), Asiancorn borers (Ostrinia furnacalis), 멸강충(Mythimna spp.),corn ear worm (Helicoverpa spp.) 등의 충이나, 가장 큰 영향을 주는 요인은 downy mildew이다. 4. 비생물적 생산성 제한요인은 토양의 산성화에 따른 척박토양과 관개가 자유롭지 못한 전작 지대의 한발피해 등이며, 경제ㆍ사회적 제한요인으로는 비료, 농약 등 농자재 투입 비용과 hybrid종자 가격 등이다. 5. 인도네시아에 적응하는 품종 개발 시 생산성 제한 요인을 극복하기 위한 주요 타겟 형질은 환경 스트레스 내성으로서, 특히 downy mildew 저항성과 내산성, 내건성이 요구된다. Indonesia, which located at between five degree north latitude and ten degree south latitude, have distinct dry and rainy season as tropical climate. After 2009, area of maize cultivation isapproximately 4,000,000 ha, and production of maize is maintained over 17,000,000 ton. Jawa island has possessed about 50% of harvest area and production. In 2014, yield per unit area as 4.95 ton/ha, is 3 times increase compared to 1980’s. However, it shows severe regional difference because productivity variation is 2.5 ~ 7.32ton/ha territorially. Major constraints of maize production in Indonesia are; As biotic stress factors, diseases such as downy mildew (Peronosclerospora), maydis leaf blights (Helminthosporium spp.), leaf spots (Curvularia spp.), rusts (Puccinia polysora), stalk and ear rots (Fusarium spp., Diplodia spp.), and banded leaf and sheath blight (BLSB, Rhizoctonia solani), insects such as a genus of weevils (Sitophilus spp.), shoot flies (Atherigona spp.), asian corn borers (Ostrinia furnacalis), armyworm (Mythimna spp.), and corn ear worm (Helicoverpa spp.) are popular. Among them, the most major constraint is downy mildew. As abiotic stress factors, low soil fertility and drought stress is major effect on yield decrease. As business and social factors, major constraints are agro-materials (including fertilizer and pesticide) costs and hybrid seed price. To overcome these constraints during varieties are developed, main target trait is environment stress resistance. Especially, it seems that downy mildew resistance, acid resistance and drought resistance will be improved.
