아스퍼거장애 유아의 부적응 행동 중재를 위한 또래개입 사회상황 이야기 효과
김정일 국립특수교육원 2004 특수교육연구 Vol.11 No.2
자폐스팩트럼장애 유아들의 의사소통 사회적 기술증진 방법에 대한 많은 연구들이 사회상황 이야기의 효과에 초점을 두고 있다. 본 연구는 또래개입 사회상황 이야기가 자폐스팩트럼장애 유아들의 부적응 행동 중재에 미치는 영향을 연구하였다. 아스퍼거장애로 진단받은 유아들 중 일반교육기관에 다니고 있는 두 명의 유아들이 본 연구의 중재대상 유아로 참여하였으며, 두 명의 일반발달 유아들이 또래개입자로 참여하였다. 연구설계는 다중기초선 설계와 ABAB설계를 복합하여 사용하였으며, 협력과제내 부적절한 행동과 적절한 행동을 표적행동으로 설정하여 25분 동안 10초-부분동간기록법을 사용하여 자료수집 하였다. 중재프로그램은 일반발달 또래들과 협력과제를 수행하는 상황 안에서 적절한 행동에 대한 단서가 내포된 또래개입 사회상황 이야기 전략을 사용하였다. 연구결과, 또래개입 사회상황 이야기 중재는 아스퍼거장애 유아들의 협력과제 내 부적절한 행동발생율을 감소시키고, 과제에 참여하는 과제이행 행동발생율의 증가를 나타냈다. 또한, 중재이후 일반발달 또래들이 중재대상 유아와 놀이하고 싶은 정도를 평가한 또래수용도가 중재이전에 비해 눈에 띄게 증가하였다. Autism spectrum disorder is characterized by major deficits in social skills, which relates closely to maladaptive social behaviors in a peer group. The present study examined the effect of peer-mediated social story intervention to decrease in inappropriate class behaviors and increase in on-task behavior of preschoolers with autism spectrum disorders. Using a multiple baseline design across settings and ABA design, the study targeted increase in crying, out-of-seat, and screaming behaviors as inappropriate class behaviors and on-task behavior in a peer-group activity time through peer-mediated social story intervention. The results showed that the intervention produced increase in on-task behavior and decrease in inappropriate behaviors in a peer-group activity as well as increase in acceptance level by their typically developing peers.

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.
