A 1050 알루미늄과 SS41 軟鋼과의 브레이징 接合에 關한 硏究
金正一 木浦海洋大學校 1995 論文集 Vol.3 No.1
The Purpose of this study is to investigate the effect of Ni plating layer thickness and lap ratio on the bonding strength of the brazed bonding of Al/SS41. The brazing was performed under different bonding conditions such as Ni plating thickness and lap ratio. The bonding strength was evaluated by tensile tester and micro-structural analysis at the interlayer was performed by SEM. In order to improve the bonding strength, the metallic plating of Ni on the SS41 surface was used. Using the metallic plating of Ni on the SS41 surface, the wettability between filler metal and base metal was improved, therefore bonding strength was increased. An optimum lap ratio obtained through the experimental results was 3.0 in case of 10㎛ Ni plating thickness.

토끼 각막의 알카리 화상에 의한 조직병리학적 변화와 Sodium Hyaluronate의 효과
김정일,유진형 인제대학교 1992 仁濟醫學 Vol.13 No.3
토끼의 각막에 알카리에 의한 화학상을 유발시켜 시간 경과에 따른 조직병리학적 변화와 이에 미치는 Sodium Hyaluronate의 효과를 광학현미 평을 이용하여 관찰하였다. The influence of topically applied 2% Sodium hyaluronate (NaHA) and Phosphate buffer solution (PBS) was studied on the healing of rabbit corneal alkali wound, respectively. NaHA have a positive influence on the epithelial re-surfacing, especially during the initial healing phase. In NaHA-group was observed mild stromal edema and smaller endothelial cell defect when compared with that in the PBS-group. No significant difference in the repair process was observed between the NaHA-group and the PBS-group. However, NaHA is not the final solution to the treatment of corneal alkali wounds. It might exert a positive influence on the healing process and may serve as an adjunct in the clinical treatment of corneal alkali wounds.

김정일 木浦海洋大學校 2003 論文集 Vol.11 No.-
The purpose of this study is to investigate the effect of lap ratio on the bonding strength of the brazed bonding of Cu/Cu, Al/Al and Cu/Al. The adopted thickness of base metal in this experiments were 4mm which were most commonly used in various fields. An optimum lap ratio obtained through the experimental results are as follows; 1) The ratio of lap length to plate thickness which the fracture occurs at base metal is more than 1.0 in case of Cu/Cu brazed joint. An optimum lap ratio is 1.0 in case of Cu/Cu joint. 2) An optimum lap ratio is 0.75 in case of Al/Al joint. 3) An optimum lap ratio is 3.0 in case of Cu/Al joint.

김정일,맹원재,장문백 ( J . I . Kim,W . J . Maeng,M . B . Chang ) 한국축산학회 1986 한국축산학회지 Vol.28 No.2
Rice straw was treated with 4% anhydrous ammonia in a wire mesh silo and stack and 4% sodium hydroxide of the weight of rice straw dry matter (3.3% in a air dry rice straw). Treatment period with ammonia was winter time from September 23 to February 14, and chopped rice straw with 4-5 cm was sprayed with sodium hydroxide dissolved in water of 50% of straw weight and stacked for 96 hours, and then dried in a shadow. In vitro digestibility studies and goat metabolism trials with 4 × 4 Latin square design were conducted. Crude protein content of ammonia-treated rice straw, compared with 4.2% of untreated rice straw, was 11.9% (wire mesh silo) and 9.6% (stack) and increased 2.8 fold and 2.3 fold, respectively. Crude protein content of sodium hydroxide treated rice straw was 3.9% and decreased 7.1% over untreated rice straw. Digestible crude protein contents of untreated and sodium hydroxide treated rice straw were 0.6% and 0.5%, respectively, however, that of ammonia treated rice straw was 7.6% (wire mesh silo) and 5.6% (stack), which were considerably higher than untreated and sodium hydroxide treated rice straw. NDF, ADF, and cellouse contents of rice straw were decreased by ammonia and sodium hydroxide treatment. In vitro dry matter, NDF, ADF and cellouse digestibilities were increased significantly by ammonia and sodium hydroxide treatment (P$lt;0.01). Increases of in vitro digestibilities were the highest in sodium hydroxide treated rice straw and followed by ammonia treated rice straw in wire mesh silo. However, in vivo digestibilities of rice straw were the highest with ammonia treated rice straw in a wire mesh silo and were not different between ammonia treated rice straw in stack and sodium hydroxide treated rice straw. Rice straw intake increased by 62% in ammonia treatment in a wire mesh silo, by 26% in ammonia treatment in stack and by 35% in sodium hydroxide treatment (P$lt;0.05). Water intake and urine excretion were significantly increased by ammonia and sodium hydroxide treatment of rice straw (P$lt;0.05) and highest with goat fed sodium hydroxide treated rice straw. Digestible dry matter and TDN contents of untreated and ammonia treated in a wire mesh and stack and sodium hydroxide treated rice straw were 48.6%, 57.4%, 54.3% and 52.9%, and 40.5, 53.9, 47.7 and 47.9, respectively. Concentration of total VFA in rumen fluid was the highest in ammonia treated rice straw in a wire mesh silo and composition of individual VFA was not significantly different among treatment.

컴퓨터 활용 비디오 모델링이 자폐성 아동의 단어 철자쓰기 증진에 미치는 효과
김정일,허유승 한국장애인재활협회 2008 재활복지 Vol.12 No.1
본 연구는 일반초등학교 1학년에 재학하고 있는 생활연령 6.8세의 자폐성 남자 아동에게 단어쓰기 철자를 가르치기 위해 컴퓨터 활용 비디오 모델을 사용하는 중재기법의 효과를 조사하였다. 연구설계는 교대중재설계를 복합하여 활용하였다. 중재는 중재대상 아동에게 비디오 모델링을 통해 2음절로 된 5개의 새로운 단어 철자쓰기를 가르치는 1단계, 1단계에서 학습한 5개의 단어 요소에‘내’라는 소유격을 붙여 3음절의 연관성 있는 단어를 가르치는 2단계, 2단계에서 학습한 5개의 단어 요소에‘아빠(의)’라는 수식어를 붙여 4음절의 연관성 있는 단어를 가르치는 3단계로 구성되었다. 중재효과로 인한 부차적 효과를 점검하기 위하여 연구기간 동안 아동의 쓰기교과과정에 포함된 4음절 단어들의 쓰기수행도 점검하였다. 연구 결과, 중재 대상 아동의 단어철자 쓰기는 종이 위 쓰기 모델링과 점선 쓰기 모델링에 비해 현저하게 빠른 속도로 95% 이상의 정확도를 성취하였고, 중재결과 학습된 철자쓰기는 유지상황 점검 테스트에서도 크게 변화하지 않는 수준으로 유지되었다. This study examined the effect of using a computer-based video modeling to teach spelling to an elementary school child with autism spectrum disorder. Using an alternating treatment design, the intervention consisted of three phases was applied to the subject. Data on spelling based on each phase of the intervention with the subject was collected. The performance of four-syllable spelling was also evaluated to check the effectiveness of the intervention. The result showed a computer-base video modeling to teach spelling for a child with autism improved the subject spelling performance distinctively, compared to other teaching strategies. The improved performance in spelling of the subject was maintained when the intervention was withdrawn.
