조성진 한국농화학회 1968 Applied Biological Chemistry (Appl Biol Chem) Vol.9 No.1

This experiment was carried out as a part of the studies on reasonable application of nitrogen in rice plant to determine: (Ⅰ) Nitrogen absorption. and rooting of rice seedlings as affected by urea foliar application at late seedling stage (Ⅱ) Effect of leaf prunning and foliar application of urea at late heading stage on the maturation and yield of rice (Ⅲ) Effect of foliar application of urea and its time during the stage of ear formation on yield of rice plant. Results obtained are summarized as follows. Exp.I: Nitrogen absorption and rooting of rice seedlings as affected be urea foliar application at late seedling stage. 1 : The foliar application of urea plots(T₁,T₂) snowed mare N-content than non-urea foliar application plot(T0) at lane seedling stage, being significant among treatments and foliar application of urea seemed more effective in increasing the N-content of seedlings. and promoted root settlement and early growth alter the transplanting. 2 : The carbon contents of the plants of T₁, and T₂ at late seedling stage increased than T_0, and the carbon contents. of T₁ and T₂ plots became higher in amount in proportion to the nitrogen absorption as compared with those of T0. 3 : C/N ratio appeared significant among soil application plots(N₁, N₂) and foliar application of urea plots (T₁, T₂ and T_0). C/N ratio was lower in case of increased amount of nitrogen. The higher contents of nitrogen and carbon and lower C/N ratio resulted in the increment of root numbers and root lengths. Exp.II: Effect of leaf prunning and foliar application of urea at late heading stage on the maturation and yield of rice. 1 : There was a highly significant decrease in the maturing rate by severe leaf prunning. In the mean time, significant increase in maturing rate was observed with urea foliar application and it was found the more frequent application the more effective for higher maturing rate with a moderate significance. A correlationship between the level of prunning and maturing rate was enumerated to 0.961 of correlation coefficient, which indicated an increased maturing rate by the increased number of remaining leaves. 2 : The 1.000 grain weight, grain weight and hulled rice yield increased by leaf prunning in order (plot a$lt;b$lt;c$lt;d$lt;e) at the plots where upper single(a), two(b), three(c), four(d) and five leaves(e) remained, respectively, as compared with control plot(f), thus the high significance were observed among the leaf prunning. Correlation coefficient(r) of 0.925, 0.971 and 0.989, respectively, showed highly significant corrlationship between the level of leaf prunning. In the mean time, the 1000 grain weight, gram weight and hulled rice yield increased in oder at one time urea foliar application plot(B) and two times foliar application plot (A) as compared with the .yield of control plot (C), and the high significance were observed among those treatments. Hulling ratio also showed the same tendency among those treatments(C,B and A plots in order). 3 : The nitrogen and carbon contents of both panicles and leaves in the foliar application of urea were increased. C/N ratio showed a higher level only in the leaves at the urea spray plot. In the mean time, it was found a higher degree of correlationship between the hulled rice yield(0.937),the contents of nitrogen(0.952) and carbon(0.946), and C/N ratio, indicating that the higher the contents of nitrogen and carbon, and C/N ratio the higher the yield of hulled rice. Exp. III: Effect of foliar application of urea and its time during the stage of ear formation on yield of rice plant. 1 : The difference in average number of grains per ear was significant between the time of ear fertilization, showing a tendency of increase of grain number in accordance with earlier treatments although no significance was seen between methods of ear fertilization. Number of grain of 2.0% urea solution foliar application plot, 10% urea solution soil application plot, 2.0% urea solution soil application plot and the control are 65.9, 65.6, 64.4 and 63.9 grains, respectively, indicating the largest grain number in the 2.0% urea foliar application plot among the others. 2 : Maturing rates showed a significance between time of ear fertilization, showing a tendency of increase in the rate with the time lagging until 7 days before Baring. Those of A₁, A₃, A₂ and A_0 were 89.8%. 89,4% 87.8% and 87.5% respectively, showing the highest of rate in A₁ and A₃ in methods of ear fertilization and being highly significant between its treatment. 3 : 1000 grain weights were highly significant between time of application, showing a tendency of increase of weights with the time lagging until days before earings as that of maturing rates. High significance was recognized between methods of ear fertilization, showing the highest in A₂ 23.18 gr. 4 : Yields per 3.3㎡ were not significant between time of ear fertilization, whereas were highly significant between methods of ear fertilization. Those of A₁, A₃, A₂ and A_0 were 1.486 ㎏, 1.491 ㎏, 1.381 ㎏ and 1.328 ㎏, respectively, showing the highest in A₁ and A₃. 5 : Hulling ratios showed significant different between time of ear fertilization, showing the highest in T₂, whereas those of methods of ear fertilization were highly significant between its treatment, Those of A₁, A₃, A₂ and A_0 were 84.72%, 84.06%, 83.29%, and 82.56% respectively, showing the highest m A₂ and A₃ among others. 6 : Yields of hulled rice per 3.3 ㎡ showed significant different between time of ear fertilization, showing the highest in T₁, 1.192 ㎏. Whereas, those were highly significant between methods of ear fertilization. Those of A₁, A₃, A₂ and A_0 were 1.259 ㎏, 1.254 ㎏, 1.149 ㎏ and 1.095 ㎏, respectively, showing the highest in A₁ and A₂. 7 : Contents of nitrogen on rice plant increased in case of nitrogen application as ear fertilizer and showed that the case of urea foliar application was more effective than that of soil application, showing the increased nitrogen content of rice plant was accompanied by carbon content.

Objective: To evaluate the safety of incidental appendectomy during gynecologic laparoscopic surgery. Methods: Thirty incidental appendectomies were performed in patients undergoing gynecologic laparoscopic surgery at National Medical Center from October 1997 to October 1998. Operations were performed consequently by same operator. Appendix and mesoappendix was separated by bipolar electrocoagulator, and 2 endoloops were applicated at base of appendix with cauterization and milking of content, 1 endoloop was applicated at 1-1.5cm above base, and then cauterized site was cut with hook scissors. We analyzed operation times, appendical pathology, intraoperative and postoperative complications. Results: Operating times were 6 min to 12 min. Appendical histologic finding included normal in 16 cases[53%], fecal material of appendical lumen in 8 cases[27%], periappendical adhesion in 4 cases[13%], endometriosis in 1 case[3%], and mucocele in 1 case[3%]. Except for transient fever[$gt;37.5°] in 4 cases[13%] and epigastric & shoulder pain in 3 cases[10%], there were no intraoperative and postoperative complications. Conclusion: We conclude that in the hands of experienced endoscopists risk are minimal, and incidental appendectomy during gynecologic laparoscopic surgery can be performed safely.

Differential expression of conserved germ line markers, and delayed segregationof male and female primordial germ cells in a hermaphrodite, the leech Helobdella

조성진 한국발생생물학회 2013 한국발생생물학회 학술발표대회 Vol.2013 No.8

In sexually reproducing animals, primordial germ cells (PGCs) are often set aside early in embryogenesis, a strategy which minimizes the risk of genomic damage associated with replication and mitosis during the cell cycle. Here, we have used germ line markers (piwi, vasa and nanos) and micro-injected cell lineage tracers to show that PGC specification in the leech genus Helobdella follows a different scenario: in this hermaphrodite, the male and female PGCs segregate from somatic lineages only after more than 20 rounds of zygotic mitosis; the male and female PGCs share the same (mesodermal) cell lineage for 19 rounds of zygotic mitosis. Moreover, while all three markers are expressed in both male and female reproductive tissues of the adult, they are expressed differentially between the male and female PGCs of the developing embryo: piwi and vasa are expressed preferentially in female PGCs at a time when nanos is expressed preferentially in male PGCs. A priori, the delayed segregation of male and female PGCs from somatic tissues and from one another increases the probability of mutations affecting both male and female PGCs of a given individual. We speculate that this suite of features, combined with a capacity for selffertilization, may contribute to the dramatically rearranged genome of Helobdella robusta relative to various other animals.

조성진,김용평 慶熙大學校 레이저 工學硏究所 2002 레이저공학 Vol.13 No.-

A theory is presented for thulium-doped ZBLAN fiber amplifiers and lasers that are upconversion pumped by a single source at 1140 nm and emit in the blue spectrum at 480 nm. This computer model describes the performance of such lasers with good accuracy despite the complicated three-step upconversion mechanisms and are able to specify the corresponding spectroscopic parameters. We discuss the relevance of these processes to the 480 nm laser performance. The laser model is compared with published experimental data.

Pituitary Macroincidentaloma - 증례보고 -

조성진,심재준,장재칠,김범태,신원한,최순관,변박장,Cho, Sung Jin,Shim, Jae Joon,Chang, Jae Chil,Kim, Bum Tae,Shin, Won Han,Choi, Soon Kwan,Byun, Bark Jang 대한신경외과학회 2001 Journal of Korean neurosurgical society Vol.30 No.8

With improvements in diagnostic imaging techniques for the brain, pituitary tumors without neurological signs or symptoms have occasionally been found. To evaluate therapeutic strategy for incidentally found pituitary tumors ("pituitary incidentaloma"), we analyzed the result of magnetic resonance imaging findings and of ophthalmological and endocrinological studies in 3 cases with follow up. Incidentally found functioning tumors were excluded. All of 3 cases is greater than 10mm in tumor size("pituitary macroincidentaloma"). The follow-up period was 49 months, 16 months and 6 months(mean, 25.3 months) in each case. There was no evidence of tumor enlargement, endocrinological problems and visual field defect during follow-up period. Patients with pituitary incidentalomas usually follow a benign course and neurosurgical intervention is not initially required in the management even those greater than 10mm in diameter. Observation over time may be good approach to the patient with a pituitary macroincidentaloma to avoid the unnecessary risk for surgery in a patients with a stable mass.

2LL-4 물에 용해가능한 희생층을 이용한 신축성 실리콘 박막 태양전지

조성진 한국공업화학회 2017 한국공업화학회 연구논문 초록집 Vol.2017 No.1

웨어러블 및 생체친화적 전자소자에 필수적인 휴대용 전원으로 신축성 태양전지의 사용이 주목 받고 있다. 그 중 상대적으로 높은 태양전지 특성을 가지지만, 딱딱하고 고온 공정으로 제작되는 무기물 태양전지를 신축성 태양전지로 사용하기 위해 buckling, serpentine, stiff island 등의 구조적인 접근에 관한 연구가 많이 진행 되었다. 이러한 구조적인 접근을 바탕으로 한 연구들은 제작된 반도체 소자를 딱딱한 기판으로부터 신축성 기판으로 옮기는 트랜스퍼 프린팅 기술과 적합한 희생층, 그리고 원하는 모양으로의 패터닝 공정이 필수적이다. 본 연구에서는 신축성 실리콘 박막 태양전지 제작을 위해 물에 녹는 산화게르마늄층을 희생층으로 사용한 트랜스퍼 프린팅 공정을 개발하였다. 또한 제조 공정이 간단하며, 원하는 형태로 쉽게 변형이 가능하다는 장점이 있지만, 단 방향 응력에만 신축성을 가진다는 단점이 있는 물결 구조를 교차 물결 구조로 변형하여 여러 방향의 응력에도 손상을 받지 않는 신축성 소자를 제작하였다. 본 연구를 통해 신축성 휴대용 전원으로써 무기물 박막 태양전지의 적용 분야가 확대될 것으로 기대된다.
