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.

조성진 한국교양교육학회 2013 교양교육연구 Vol.7 No.4

This field experimental study investigated the positive effect of coaching(independent variable) on self-efficacy, family relations, and performance. In a quasi-experimental design, 17 university students were assigned to an experimental group, and 17 university students were assigned to a control group. An experimental group in the coaching program for university students, which consists of 20 hours of coaching training workshop and 12 face-to-face coaching communication sessions for 12 weeks with the author of this paper and professional coaches. We did not provided coaching to control group. ANCOVA was used as covariate, which showed the effect of coaching on self-efficacy, family relations, and performance. After three months of coaching, questionnaires were administered again. For control group, there was no difference between before and after measurement for each dependent variable. However, there was statistically significant difference between before and after measurement for experimental group. This result shows that coaching causes increase in the level of self-efficacy, family relations, and performance. 본 연구는 독립변수인 코칭이 종속변수인 자기효능감, 가족관계 및 성과에 긍정적인 영향을 미친다는 것을 대학생을 대상으로 한 현장유사실험연구(quasi-experimental study)를 통해 검증한 것이다. 실험군(群)에는 한 대학교의 코칭 프로그램에 참가한 17명의 대학생을 배정하였고, 코칭을 받지 않은 17명의 대학생은 대조군(群)에 배정하였다. 실험연구를 위해 2010년 3월부터 5월까지 주1회씩 12주에 걸쳐 1:1로 대학생들에게 코칭을 실시했고, 대조군의 대학생들에겐 코칭을 전혀 실시하지 않았다. 두 집단을 대상으로 코칭 전후 시점에서 자기효능감, 가족관계 및 성과(학점)에 대한 사전 및 사후 측정을 실시했고, 공분산분석(ANCOVA)을 실시하여 사전·사후 측정치 변화를 확인하였다. 연구 결과, 대조군은 자기효능감, 가족관계 및 성과에 있어 두 시점 간에 통계적으로 유의한 변화가 없었으나, 실험군은 자기효능감과 가족관계에서 두 시점 간에 통계적으로 유의한 차이를 보였고, 성과에 있어서도 의미 있는 변화를 보였다. 이런 변화는 코칭으로 기인한 것으로 검증되었다. 본 연구는 대학생 코칭 프로그램의 효과를 처음으로 검증했다는 점, 코칭 효과를 검증하기 위해 특정 시점에서의 설문조사를 통한 상관관계 분석방법에 의존한 연구와 달리 직접 현장실험을 실시했다는 점에서 선행연구와 차별화된다.

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.

최근 무선 통신의 출현과 PDA, 스마트 카드와 같은 휴대용 장치의 발전으로 인해, 이에 대한 보안과 개인 정보보호에 대한 필요성이 대두되면서 암호학의 적용에 관심이 높아지고 있다. CA는 암 복호화를 공유할 수 있는 하드웨어 구현이 용이하다. 본 논문에서는 전이규칙 60, 102 또는 204를 갖는 선형 하이브리드 셀룰라 오토마타가 그룹 셀룰라 오토마타가 되는 조건을 제안하고 이 셀룰라 오토마타로부터 유도된 여원 하이브리드 그룹 CA의 상태전이 그래프에서 모든 사이클의 주기가 동일하고 가능한 최대 길이를 갖는 CA가 되기 위한 여 원벡터의 조건을 제시한다. 또한 여원 하이브리드 그룹 셀룰라 오토마타의 사이클들 간의 관계를 분석한다. 이는 Mukhopadhyay의 결과의 일반화이다. Recently with the ever increasing growth of data communication, the need for security and privacy has become a necessity. The advent of wireless communication and other handheld devices like Personal Digital Assistants and smart cards have made the implementation of cryptosystems a major issue. The Cellular Automata(CA) can be programmed to implement hardware sharing between the encryption and decryption. In this paper, we give conditions for a linear hybrid cellular automata with 60, 102 or 204 to be a linear hybrid group cellular automata C. And we present the conditions which the complemented hybrid group cellular automata C' with complement vectors derived from C has maximum equal lengths in the state transition diagram of C' Also we analyze the relationship among cycles of C' These results generalize Mukhopadhyay's results.
