김영진,김영진,김종희 한국콘크리트학회 1998 콘크리트학회지 Vol.10 No.6

본 연구는 수직전단하중에 대한 프리캐스트 바닥판간 이음부거동을 규명하고 수직전단력 전달에 유리한 이음부 구조도출을 위해 female-female 형식의 이음부를 제안하고, 실험 및 유한요소해석을 수행한 것이다. 경사각, 이음부깊이/높이 및 구속응력을 변수로 총 18개의 실험체에 대한 실험 및 유한요소해석결과 ,이음부의균열저항성 개선을 위해서는 경사각이 60。, D/H가 1/4일 경우가 유리하며 측방향구속으로 이음부를 압축상태로 유지하는 것이 이음부 균열방지에 효과적임을 알았다. Increase of traffic volume in recent years results in deterioration of the bridge slab, which is directly subjected ot vehicle loads. Where extensive repair is necessary, replacement or enhancement of load carrying capacity using full depth precast concrete deck is often the most practical solution. Precast deck system has transverse joints between adjacent precast decks. Vertical shear forces occur when a vehicle wheel load is carried by precast decks and the joints are used to transfer the load to an adjacent deck. Effective load transfer between precast decks is critical for integral behavior. Finite element analysis and tests were run on the proposed femal-to-female type joint. 18 joint specimens were tested to investigate the effects of angle. D/H, and confining stress under static load. Results indicate joint with angle of 60$^{\circ}$ and D/H of 1/4 shows the improved load carrying capacity on crack. It is effective in protecting the cracking of joints to keep the joint in compression using confining stress.

목적: 전방십자인대 재건술을 시행하고 발생된 전방십자인대 이완에 대해서 고주파 에너지를 이용한 열 수축을 시행하고 기능적인 이점이 있는지 알아보고자 하였다. 대상 및 방법: 1999년 10월부터 2006년 3월까지 관절경하에 전방십자인대 재건술을 시행하고 이차 관절경 수술을 시행한 133례중에서 재건된 전방십자인대가 이완되고 긴장성이 없어 보이는 16례를 대상으로 하였고, 평균 추시 기간은 20.4개월이었으며, 평균 나이는 33.5세이었고, 12례가 남자, 4례가 여자였다. 이완된 전방십자인대에 대해서 2 단계 강도의 양극성 고주파 에너지를 이용한 열 수축을 시행하였다. 객관적 및 주관적 평가 지표로는 관절 운동 각도, Lysholm 슬관절 점수, Tegner 활동 점수, Lachman 검사, pivot shift 검사, IKDC 점수 등을 이용하였다. 통계학적인 검증은 Wilcoxon signed-rank test를 이용하여 유의 수준 0.05에서 판정하였다 결과: 평균 Lysholm 슬관절 점수는 술전 평균 $82.2{\pm}5.2(77{\sim}85)$점에서 $85.2{\pm}4.8(82{\sim}90)$점으로 통계학적 의미가 있는 좋은결과를 보였다(P=0.04). 전방 스트레스 방사선 사진 상에서 술전 평균 $5.4{\pm}4.6(3{\sim}10) mm$에서 술후 평균 $2.1{\pm}1.9(0{\sim}4)mm$의 전방 전위 소견이 관찰되어 의미 있는 통계학적으로 의미 있는 감소 소견이 관찰되었다(P=0.02). Lachman 검사, IKDC 점수 등은 술전에 비해 의미 있는 차이가 있었지만(P=0.04), 슬관절 관절 운동의 정도, Tegner 활동 점수는 의미 있는 차이가 없었다. 결론: 전방십자인대 재건술 이후에 발생되는 전방십자인대 이완에서 고주파 에너지를 이용한 열 수축 방법은 안전하면서도 증상 호전이 기대되므로 시도해 볼 수 있는 좋은 술식으로 사료된다. Purpose: To evaluate the clinical results of the patients who underwent radiofrequency thermal shrinkage (RFTS) for treatment of anterior cruciate ligament (ACL) laxity after ACL reconstruction. Material and Methods: From October 1999 to March 2006, we performed 133 cases of ACL reconstruction. Among them we experienced 16 patients who had the laxity of reconstructed ACL in second look arthroscopy. Mean follow-up was 20.4 months. Mean age was 33.5 years. 12 cases were male and 4 cases were female. The elongated ACL were treated by bipolar radiofrequency energy with an output of grade II. Subjective and objective parameters were utilized in analyses, such as: the mean range of motion, Lysholm knee score, Tegner activity score, Lachman test, IKDC score. Wilcoxon signed-rank test was used to perform the data analysis. P<0.05 was considered to be statistically significant. Results: Postoperative mean Lysholm knee score (preop: $82.2{\pm}5.2(77{\sim}85))$ (P=0.04), postop: $85.2{\pm}4.8$(82-90)) and anterior displacement by the Telos stress test (preop: $5.4{\pm}4.6(3{\sim}10)mm$, postop: $2.1{\pm}1.9(0{\sim}4)mm)$ (P=0.02), Lachman's test, and IKDC scores (P=0.04) demonstrated significant differences statistically compared to the preoperative. There were no statistical differences in mean range of motion, Tegner activity scale. Conclusions: Arthroscopic shrinkage for the ACL laxity after ACL reconstruction with radiofrequency device showed good clinical results and was applicable operative technique.

Ti - plasmind vector system 을 이용한 담배의 형질전환

김영진,방재욱,백상기,박성원,최상태 한국유전학회 1992 Genes & Genomics Vol.14 No.3

A study on the transformation of the tobacco plant(Nicotiana tabacum cv. Br21, N. tabacum cv. NC82) using Ti-plasmid vector pEND4K containing Zea mays transposable element(Ac) was carried out to obtain a mutant tobacco cell line and to use gene tagging system. Transformed E. coli and Agrobacterium tumefaciens were confirmed by the resistant ability to the appropriate antibiotics and the size of DNA restriction fragments. Transformed tobacco cells were selected in the selection media (MS) containing 0.5㎎/ℓ of 2, 4-D, 2㎎/ℓ of kinetin, 100㎎/ℓ of kanamycin and 150㎎/ℓ of carbenicillin. Calli were induced in both the callus and the shoot induction media at a frequency of below 20%, and the growth of calli in both media was very poor compared with that of normal calli. Transformed calli were not able to grow in the next selection media and turned to white yellow. Regenerated tobacco plants were obtained in the modified MS selection medium containing 1.0㎎/ℓ of BA, 0.1㎎/ℓ of NAA, 100㎎/ℓ of kanamycin and 150㎎/ℓ of carbenicillin. The regenerated tobacco plant leaf tissues were resistant to kanamycin upto 1000㎎/ℓ. The insertion of a Ac in transformed tobacco plant was confirmed by Southern blot hybridization. The regenerated tobacco seedlings were survived at the concentration of 100 mg/ml of kanamycin.

국소적 치아이형성증(regional odontodysplasia)에 대한 증례보고

남순현,손덕일,김현정,김영진 大韓小兒齒科學會 1997 大韓小兒齒科學會誌 Vol.24 No.1

Odontodysplasia is a rare developmental anomaly of tooth formation in which hard tissue are affected. Odontodyplasia affects the primary and permanent dentitions in the maxilla, mandible, or both jaws. The maxilla is involved twice as often as the mandible. The condition is more common in female than in male patients and in the anterior than in the posterior regions. The clinical manifestation of odontodysplasia are hypoplasia and hypocalcification of the enamel and dentin of affected teeth. Teeth tend to be small and discolored, with short roots and widely open pulp canal. Delayed eruption of affected teeth with abscess formation is common. Radiographically teeth assume a faint radiolucent image ("ghost teeth"). enamel and dentin appear thin and are similar in radiodensity. The pulp chambers are often larger than normal, calcifications(pulp stone and denticle) are found within them. The etiology of regional odontodysplasia is unknown. However, several causes have been discussed, including somatic mutation, local circulatory disorders, local trauma, failure of migration and differentiation of neural crest cells, local infection.

악성 섬유성 조직구종에 관한 연구

최의환,오필교,김영진 大韓口腔顎顔面 放射線學會 1994 Imaging Science in Dentistry Vol.24 No.2

Malignant fibrous histiocytoma(MFH) is relatively rare in the oro-maxillofacial region, particularly in the oral cavity. MFH usually arise in the extremities, the thigh being the most common site. The incidence of malignant fibrous histiocytoma in bones is rather low compared with that in soft tissues. MFH is predominant in the 40s and 50s. Histologically, the lesion are said to show high cellularity with fibrous stroma, cellular and unclear pleomorphism, and admixture of fibroblast-like spindle cells, which tend to be arranged in whorls or cartwheel or storiform patterns, rounded mononuclear cells and multinucleated giant cells. The cells frequently have abundant eosinophilic cytoplasm which has a foamy or vesicular appearance. Treatment consists of varying combinations of radiation therapy, chemotherapy, and surgery. We have observed a case of malignant fibrous histiocytoma occured in the right maxilla of 32-year-old woman.

도립진자 시스템의 안정화 제어에 관한 연구

金永珍 東義大學校 産業技術開發硏究所 1997 産業技術硏究誌 Vol.11 No.-

In this paper, in the system, a dynamic modelling is given and analyzed by considerising the non linear characteristic. Because the system is sensitive on the parameter-fluctuation, the linear controller for sustaining the desired state in the system with a inverted pendulum with choosing the algorithm for determining the suitable feedback coefficients is designed. The designed controller is a state-feedback controller which is feedbacked by state-variables, the coefficients of this controller are determined by pole-placement and the effectiveness of the proposed controller is confirmed through the results of simulation.
