유산균 접종이 옥수수와 수수silage의 품질에 미치는 영향을 조사할 목적으로 L. plantarum을 대조구는 접종하지 않았고 처리구는 2×10 exp(8), 4×10 exp(8) 및 6×10 exp(8)cfu, kg^-1(fresh forage) 수준으로 접종하여 조제한 silage의 일반성분, pH 및 유기산 함량을 비교한 결과는 다음과 같다. 1. crude protein, crude ash, NDF, ADF 및 hemicellulose 함량은 접종수준이 증가할수록 높았고 moisture 및 NFE 함량은 낮았다. 2. 접종수준이 증가할수록 lactic acid와 total acid 함량은 증가한 반면 acetic acid함량과 pH는 낮았다. 3. 옥수수 silage에 비하여 수수silage에서 L. plantarum의 접종효과가 높았다. The objective of this thesis is to investigate the effects of lactic acid bacterium inoculation on the qualities of corn and sorghum silages. The control group was not inoculated : the treated group was inoculated with Lactobacillus plantarum of the levels of 2×10 exp (8), 4×10 exp(8) and 6×10 exp(8) cfu. Kg^-1(fresh forage). The chemical components, pH and organic acid contents of the developed silages were measured and compared. The results obtained are as follows : 1. As the level of inoculation was higher, the contents of crude protein, crude ash, NDF, ADF and hemicellulose became larger, but the contents of moisture and NFE became smaller. 2. As the level of inoculation was higher, the contents of lactic acid and total acid became larger, but the acetic acid content and the pH became smaller. 3. The inoculation effect of L. plantarum was greater in the sorghum silage than in the corn silage.

鄭場龍,文勝式,朴成振 진주산업대학교 1986 論文集 Vol.24 No.-

본 試驗은 初産日齡이 産卵能力과 卵重에 미치는 영향을 살펴보고자 1986년 2월 1일부터 11월 30일까지 晋州農林專門大學 부속 動物飼育場에서 실시하였다. 初産日齡이 166~168일의 닭들이 165일 이전 또는 169일 이후의 개체들보다 産卵能力이 우수하였고 平均卵重은 初産日齡間에 차이가 없이 비슷하였다. 90%이상 産卵지속은 초산일령이 166~168일의 닭들이 26주령시부터 48주령시까지 지속되어 가장 우수하였다. For the purpose of identifing the reationship between the first egg day and other economic traits; egg production and egg weight, this experiment was divided 160 birds(DEKLB-Warren Sex-Sal-Link) into four first egg day groups and observed egg number and gee weight every day during 10 months form 1st February, 1986 to 30st November, the same year at Animal farm, Chin Ju Agricultural and Forestry Junior Technical College. Bird showing 166-168 day in first egg day layed the most eggs among four groups and they produced similar to average egg weight between the four groups. In egg production above 90%, 166-168 day group showed the best record as a 26-48 week.

Ion Beam을 이용한 Ni-Co-Cu Alloy Thin Film의 Dry Etching에 관한 연구

안정식,장문식,이규용 경북대학교 센서기술연구소 1998 센서技術學術大會論文集 Vol.9 No.1

Much effort has been made worldwide in dry etching of new thin film by IBE, IRE, ECR etc. In this study, dry etching of Ni-Co-Cu alloy thin film grown by IBD on a glass substrate was performed using Ar^(+) or N_(2)^(+) ions of 2KeV as a function of ion dose by high current DuoPigatron type ion source. The experimental results showed that surface morphology of the Ar^(+) beam etched PR was rough at 2KeV energy, but the N_(2)^(+) beam etched was smoother. It could be surmised that an increase in the atomic radius was correlated to an increase in the energy of the bombarding ions, which leaded to damaged PR layer due to the thermal phenomena, such as thermal spike, cascade, etc. in PR surface. As the result, pattern were destroyed partially with the melted and flowed over area. Dry etching of the thin film, in turn, was more successful in N_(2)^(+) beam etching than in Ar^(+) beam and it seemed that N_(2) ion was more effective in removing the currently used PR. Observed results from SEM showed that the resolution was increased with increasing N_(2) ion dose up to 3.6X10^(19) ions/cm^(2) at 2KeV, beyond this proper ion dose the resolution was decreased and leaded the damaged pattern.

정장용,박희성,문승식,박성진 진주산업대학교 1993 論文集 Vol.32 No.-

This experiment was carried out to develop a new technique of identifying XX or XY-bearing bisected embryos prior to implantation by immunological method. H-Y antiserum prepared in inbred Wistar female rats by repeated immunization with spleen cells from males of the same strain. The reactivity of H-Y antibody was confirmed by culturing mouse embryos in the medium containing H-Y antiserum and complement obtained from the guinea pig. The optimal condition for the activity of H-Y antibody was also investigated by culturing embryos under the concentration or affected H-Y antibody and culture rate. The bisection rate of mouse embryo at 4-cell stage(64.6%) was significantly(P<0.05) low than 8-cell(76.0%), morula(81.2%) or blastocyst(81.3%). And not significantly(P<0.05) different from 4 to 8-cell and morula to blastocyst stage embryos. When the bisected embryos without any damage from microsurgery were cultured in vitro up to twin blastocyst or twin reformated blastocyst, the in vitro development of demi-embryos bisected at morula to blastocyst was 81.6 to 84.7%. However, the in vitro development of demi-embryos bisected at 4-cell(31.6%) to 8-cell(37.8%) stage was significantly(P<0.05) lower. The lysis-rate of bisected 4- to 8-cell and morula to blastocyst embryo was 42.7 and 58.6%. The morphology embryos of zona-free and intact embryos showed the embryos lysis rate of 48.5 and 42.7% respectively(P<0.05).
