趙弘來 건국대학교 1988 論文集 Vol.26 No.1

This experiments were conducted to study the effect of sources and levers of protein on the rumen microbial growth and energy utilization by washed cell suspension of rumen microbes. Protein sources were 100% casein.N,100% urea-N and casein-N .urea-N (25 : 75) and protein levels were 5, 7, 9, 11, 13, 15 and 17% of energy sources in a dry matter basis. Source of energy was starch+cellulose(50 : 50). The results obtained were as follows ; 1. NH3-N concentration(mg/100ml), under the casein, was the highest of 1.95 at 11% protein level, and ammonia concentration was increased by increasing crude protein level in urea and casein + urea, proportionally (urea, 6.50-18.25, casein+urea, 5.80-13.50)(P <0.01). 2. Starch utilization(mg/100ml) in the casein + urea was higher 24.73% than casein and 42.51% than urea (P <0.01). Cellulose utilization(mg/100ml) in the casein+urea was higher 63.84% than urea and 66.01% than casein(P <0.01). 3. Microbial protein synthesis(mg/100ml) was the highest in the casein+ urea and increased as increasing protein level in the incubation medium as 26.25, 33.90, 33.45, 41.10, 51.70, 89.99 and 99.25mg at 5, 7, 9, 11, 13, 15 and 17% protein levels, respectively.

육성-비육돈에 있어서 항균제의 첨가효과

金大鎭,李尙勳,趙弘來 東亞大學校 大學院 1986 大學院論文集 Vol.11 No.-

This experiment was conducted to examine the effect of copper sulfate, nitrovin and virginiamycin in grower-finisher ration on the pig performance of body weight gain and feed conversion. These antimicrobial agent of copper sulfate, nitrovin and virginiamycin in grower and finisher diets were added 175ppm, 20ppm and 20ppm, respectively. Pigs fed rations containing nitrovin(837gram) of average daily body weight gain were more efficient than those of copper sulfate(815gram) and virginiamycin(804gram), but rations added nitrovin(2.90) was not improved than those of copper sulfate (2.77) and virginiamycin(2.79) in feed conversion(P<0.05).

Hop2 and Sae3 Are Required for Dmc1-Mediated Double-Strand Break Repair via Homolog Bias during Meiosis

Cho, Hong-Rae,Kong, Yoon-Ju,Hong, Soo-Gil,Kim, Keun Pil Korean Society for Molecular and Cellular Biology 2016 Molecules and cells Vol.39 No.7

During meiosis, exchange of DNA segments occurs between paired homologous chromosomes in order to produce recombinant chromosomes, helping to increase genetic diversity within a species. This genetic exchange process is tightly controlled by the eukaryotic RecA homologs Rad51 and Dmc1, which are involved in strand exchange of meiotic recombination, with Rad51 participating specifically in mitotic recombination. Meiotic recombination requires an interaction between homologous chromosomes to repair programmed double-strand breaks (DSBs). In this study, we investigated the budding yeast meiosis-specific proteins Hop2 and Sae3, which function in the Dmc1-dependent pathway. This pathway mediates the homology searching and strand invasion processes. Mek1 kinase participates in switching meiotic recombination from sister bias to homolog bias after DSB formation. In the absence of Hop2 and Sae3, DSBs were produced normally, but showed defects in the DSB-to-single-end invasion transition mediated by Dmc1 and auxiliary factors, and mutant strains failed to complete proper chromosome segregation. However, in the absence of Mek1 kinase activity, Rad51-dependent recombination progressed via sister bias in the $hop2{\Delta}$ or $sae3{\Delta}$ mutants, even in the presence of Dmc1. Thus, Hop2 and Sae3 actively modulate Dmc1-dependent recombination, effectively progressing homolog bias, a process requiring Mek1 kinase activation.

Cho, Hong-Rae,Lee, Jin-Kee Korean Mathematical Society 2009 대한수학회논문집 Vol.24 No.2

We investigate the boundary values of the holomorphic mean Lipschitz function. In fact, we prove that the admissible limit exists at every boundary point of the unit ball for the holomorphic mean Lipschitz functions under some assumptions on the Lipschitz order. Moreover, we get embedding theorems of holomorphic mean Lipschitz spaces into Hardy spaces or into the Bloch space on the unit ball in $\mathbb{C}_n$.

Soil compaction is affected by soil texture, organic matter (OM), strength (ST) and soil moisture, which is difficult to understand the degree and effects of related factors. The purpose of the study is to assess the impact of them on the compaction with bulk density (BD). The analysis was conducted with data collected from national-wide monitoring sites including 105 upland soils, 246 orchard soils, and 408 paddy soils between 2009 and 2012. The distributions of soil physical properties were measured. The correlation and multi linear regression analysis were performed between soil physical properties using SAS. The regression equation of BD(y) includes ST, gravitational water contents (GWC), and OM as variables commonly, having additional factors, clay content and sand content in paddy soil and upland soil for only subsoil (p<0.001). Our results show that the BD could be explained about 40~50% by various physical properties. The regression was mainly determined by ST in orchard and upland soil and by the GWC in paddy soil. To mitigate soil compaction, it is important to maintain the proper level of OM in upland soil and to consider the moisture condition with soil texture in paddy soil when making work plan. Furthermore, it would be recommended the management criteria classified by soil texture for the paddy soils.

Cho, Hong Rae Korean Mathematical Society 2016 대한수학회보 Vol.53 No.3

We study Toeplitz operators $T_{\nu}$ on generalized Fock spaces $F^2_{\phi}$ with a locally finite positive Borel measures ${\nu}$ as symbols. We characterize operator-theoretic properties (boundedness and compactness) of $T_{\nu}$ in terms of the Fock-Carleson measure and the Berezin transform ${\tilde{\nu}}$.
