수도재배(水滔栽培)에 기계이앙(機械移秧)을 실시(實施)하기 위(爲)하여 조생통일외(早生統一外) 3개(固) 품종(品種)을 4월(月) 16일(日)부터 10일(日) 간격(間隔)으로 3회(回) 상자육묘(箱子育苗)하고 40일묘(日苗)를 이앙기(移秧機)로 이양(移秧)하였던 바 묘(苗)의 생육(生育)과 기계이앙후본답(機械移秧後本畓)에서의 수도(水滔)의 생육(生育)과 수량(收量)을 조사(調査)한 결과(結果)를 요약(要約)하면 다음과 같다. 1. 40일묘(日苗)의 초장(草長)과 엽수(葉數)는 관행육묘(慣行育苗)에 비(比)해 상자육묘구(箱子育苗區)에서 현저(顯著)히 짧은 경향(傾向)이었으며 상자육묘(箱子育苗)의 경우 물못자리 상자육묘구(箱子育苗區)의 초장(草長) 및 엽수(葉數)가 밭못자리구(區)보다 현저(顯著)히 길었다. 2. 40일묘(日苗)를 단근(斷根)하여 발근력(發根力)을 시험(試驗)한 결과(結果) 상자육묘구(箱子育苗區)의 발근력(發根力)은 관행육묘구(관行育苗區)의 발근력(發根力)에 비(比)해 현저(顯著)히 낮았다. 한편 같은 상자육묘구(箱子育苗區)에서는 물못자리 상자육묘구(箱子育苗區)의 묘(苗)의 발근력(發根力)이 밭못자리에 비(比)해 높은 경향(傾向)이었다. 3. 본시험(本試驗)에 공시(供試)된 유일계(流一系) 품종(品種)은 상자육묘(箱子育苗)의 경우 못자리에서 25~30일(日) 경(頃) 부터 잎의 상부가 황변(黃變) 내지 황적색(黃赤色)으로 변(變)하고 생육(生育)이 거의 정지(停止)되는 현상(現像)을 나타내었다. 4. 상자육묘(箱子育苗)의 기계이앙구(機械移秧區)는 관행육묘이앙구(慣行育苗移秧區)에 비(比)해 활착(活着)이 5~7일(日) 이상(以上) 지연되었으며 출수기(出穗期)도 품종(品種)에 따라 차이(差異)가 있으나 대체로 5~7일(日) 지연되었다. 5. 정조수량(正粗收量)은 유신(維新)의 관행재배구(慣行栽培區)에 비(比)해 모두 약간의 감수(減收)를 보였는데 기계이앙구내(機械移秧區內)에서는 5월(月) 26일(日) 이앙(移秧)의 경우 통일(統一)의 수량(收量)이 가장 높았고 6월(月) 15일(日)의 수량(收量)은 밀양(密陽) 15호(號)가 가장 많았으며 기계이앙재배(機械移秧栽培)를 위(爲)한 품종(品種)의 선택(選擇)은 중요(重要)한 것으로 인정(認定)된다. 6. 수도이앙기(水滔移秧機)로는 $3.3m^2$당(當) 이앙주수(移秧株數)를 73주(株)부터 108주(株)까지 조정(調整)이 가능(可能)하며 파종밀도(播種密度)가 균일(均一)하면 결주율(缺株率) 1% 미만(未滿)의 작업정도(作業精度)로 인력이앙작업(人力移秧作業)에 비(比)하여 2조(條)의 경우 5~6배(倍)의 이앙작업능률(移秧作業能率)을 올릴 수 있으므로 단작지대(單作地帶)에서는 실용화(實用化)가 용역(容易)하리라 믿는다. 7. 이모작지대(二毛作地帶)에서는 이앙시기(移秧時期)가 한정(限定)되어 있으므로 적절(適切)한 품종(品種)의 선택(選擇)과 상자묘(箱子苗)의 육묘기술(育苗技術)이 개발(開發)된다면 수량(收量)은 감소(減少)없이 이앙작업(移秧作業)의 기계화(機械化)가 무난(無難) 할 것으로 전망(展望)된다. In order to investigate the effects of mechanical transplanting on the rice, four rice varieties including Jo-saing Tongil were planted in case nursering bed for three times with 10 days interval beginning from April 16. Fourty days old seedlings were transplanted with rice-transplanter, and growth habits of seedlings in bed and rice plants in main field and yield were examined and summerized as follows: 1. The plant height and number of leaves of the 40 days old seedling in case nursery bed were appeared to be less than those of seedlings grown in ordinary nursery bed. In case nursery, the plant height and number of leaves of seedlings grown in case nursery were apparently higher than those of seedlings grown in upland case nursery. 2. The root of 40 days old seedlings were cut to investigate the rooting ability of seedlings, and the rooting ability of the seedlings grown in the case nursery bed were apparently lower in the rooting ability compared with the seedlings grown in ordinary nursery bed. The rooting ability of the seedlings grown in the lowland case nursery was higher than that of the seedlings grown in the upland case nursery. 3. The tip of leaves of the varieties derived from Indica type were becoming yellow and yellow-red in color 25 to 30 days after planted in the case nursery bed. Those varieties was almost stopped growth. 4. The seedlings transplanted by transplanter had shown more than five to seven days of delay in rooting, compared with the seedlings transplanted by ordinary method. The heading dates was delayed five to seven days when transplanter was used, even though the delay of heading dates was a little different depending on the varieties. 5. The yields of unhulled rice were a little lower than that of Yusin variety which was hand planted. When mechanically transplanted, the yield of Tongil variety was highest in the plot where seedlings were transplanted on May 26. When transplanted on June 15, Milyang#15 was highest in yield, indicating the importance of varietal selection in mechanical transplantation. 6. The rice transplanter could transplant from 73 to 108 seedlings per $3.3m^2$. If the seeds of rice were evenly planted in the bed, the two-row rice transplanter could be used five to six times more effectively with less than one percent of missing plant compared with the hand transplanting. This suggests that rice transplanter could be utilized in the mono cropping area. 7. Since the time of transplantings in the double-cropping area is rather limitted, mechanical transplantation might be possible without reducings yield providing better adapted varieties and improved case-nursery techniques.

Background/Aims: Urinary tissue inhibitor of metalloproteinase-2 (TIMP-2) and insulin-like growth factor-binding protein 7 (IGFBP7) have been recently discovered and validated as sensitive biomarkers that can predict stage 2 or 3 acute kidney injury (AKI) development in high-risk patients. We aimed to assess whether these biomarkers could predict adverse outcomes and renal recovery in established AKI patients. Methods: This was a single-center study prospectively enrolling 124 patients diagnosed with AKI. TIMP-2, IGFBP7, neutrophil gelatinase-associated lipocalin (NGAL), and kidney injury molecule 1 (KIM-1) levels were measured at the time of diagnosis and the predictive performance of short-term outcomes and renal recovery was assessed. Results: Patients were divided into 4 quartiles according to the initial urinary TIMP-2/IGFBP7 levels. Stage 3 AKI (odds ratio [OR], 17.86), classified by the Kidney Disease Improving Global Outcomes (KDIGO), as well as the third and fourth quartiles of TIMP-2/IGFBP7 (OR, 5.75 and 44.98, respectively), were found to be independent predictors of renal replacement therapy at the time of AKI diagnosis. In addition, KDIGO stage 3 AKI (OR, 2.468) or the third of fourth quartiles of urinary TIMP-2/IGFBP7 (OR, 1.896 and 3.622, respectively) were also found to be useful in predicting nonrecovery of renal function. In a separate analysis of patients with renal recovery at discharge, initial urinary TIMP-2/IGFBP7 or urinary IGFBP7 at discharge could also predict new-onset or progressive chronic kidney disease (CKD). Conclusions: In AKI patients, urine TIMP-2/IGFBP7 could serve as a biomarker for predicting adverse outcomes, renal recovery, or the development and progression of CKD.

Kim Suyoung, Kim Chunsoo and Kim Jongsam were the citizens who experienced the turbulent period of colony and the Korean war. 1950s was the time that they started literature activities. During that period, the society was filled with war`s wound, despair, dangerous and loss. At that time, most people used variety ways in order to overcome the reality in ruins. The three poets didn`t face the tragic reality aggressively, but evadingly looked for themselves. The escape was a defensive measure to claim to be withdrew. This split mind have become the meaning of escape in poem creation and also have the feature of the three poets` poem exploration and connectivity. This study on Kim Suyoung, Kim Chunsoo and Kim Jongsam`s Imagination of Escapeness is try to find the meaning of composition, and how to form it in the history in 1950s. We want to escape from the tragic incidents such as colony, war, and national division, but we can`t forget it easily. The three poets` poetic mind use the 1950s as the background, stirred and extended from the beginning. It can be found the period situation which created the poems that were different to understand. According to the poets, 1950s was the stage of hiding oneself and also it was the period that to explore the new poems. Their imagination of escapeness was always with the establishment of new poem system. Three poets` escape and the emotion towards pure poems from the beginning of historical/individual wound are connected with experiment process. Kim Suyoung, Kim Chunsoo and Kim Jongsam`s experiment reason was started from the self-awareness and new expression. Their unique language selectness and application of expression were created from the spirit research. Accompanying with ambiguity and uncertainty, their esoteric poems pursue the originality. The spirit of experiment also was called as poetic tension.
