Dimethylphthalate와 Monoethanolamine의 에스테르 交換反應에 關한 硏究
孫秉淸,鄭舜旭 弘益大學校 1983 弘大論叢 Vol.15 No.2
The transesterification reaction between dimethyphthalate and monoethanolamine was kinetically investigated in the presence of various metal acetate catalyst at 110℃. The reaction was followed by the measurement of distilled methanol from the micro measuring cylinder The transeterification reaction was first-order kinetics with respect to the concentration of dimethylphthalate, monoethanolamine and catalyst. From the examination of relationship between rate constant and reciprocal absolute temperature, the activation energy has been caculated as 9.843 Kcal with cadmium acetate catalyst, 12.30 Kcal without catalyst. The highest reactives were found for electronegativity values between 1.4~1.7.

발굽 천행우에서 회귀성 국부 정맥무취위 활용에 관한 연구
정순욱 한국임상수의학회 1998 한국임상수의학회지 Vol.15 No.1
A retrograde intravenous regional anesthesia was applied to the extremities of 30 cows, which was showed that mean value of induction time was 13.5 seconds, duration time 74.4 minutes, frequency of injection until to keep needle into the vein 1.27, and didn't observed local and systemic complications. Under the retrograde intravenous regional anesthesia, it was possible for surgical treatment of 20 cows with various foot disorders, to resect soft tissues of extremities and claw horns, to sexarticulate 2nd phalanx without pain reactions.

Two 7 months old Korean native beef calves, which were suspected as ergotisms were referred to the Veterinary Teaching Hospitals Chonnam National University in February 1997. Those showed severe lameness as a result of a dry gangrene of the lower part of both hindlimbs which unilaterally were detached, tail necrosis and retarded growth. On the skin of the extremities of both hindlimbs were clearly appeared indented line, hypertropic granuloma and hemorrhage, from which were isolated gicrosp$\theta$rum gysiNㅁt. On the X-ray views of hindlimbs and the longitudinal sectioned metatarsal bones were not observed any changes of osteomyelitis except slightly increased osteophytes and soft tissue swelling. Clnical and anatomical observations were suggested that these calves were affected by the ergotism.

The electro-reduction of naphthalene was investigated in H₂O-N, N-dimethylformamide solution using supporting electrolyte with tetraethylammoniumbromide The main reduction product was 1,4-dihydronaphthalene, though small amounts of tetralin were also detected, but 1,2-dihydronaphthalene was not detected. Decomposition potential, H₂O, concentration of the supporting electrolyte was varied in order to obtain to maximum 1,4 - dihydronaphthalene product, 1,4-dihydronaphthalene product reached a maximum (6.53x10?mol) in 14.3v% H₂O-N, N-dimethylformamide with 0.0238M tetraethylammoniumbromide, 1,4-dihydronaphthalene product reached a minimum(3.33x10?mol) in 10v% H₂O-N, N-dimethylformamide with 0.0952M tetraethylammoniumbromide. As the H₂O and tetraethylammoniumbromide concentration increased, tetralin was not a product. As the decomposition potential between -2.2V and -2.72V decreased, 1,4-dihydronaphthalene product increased.

질병은 여러 가지 인자가 복합되어서 발생하는 것으로 특히 사료에 기인한 질병은 단순한 약품 처방만으로는 치료효과를 기대하기가 어렵다. 그러므로 발생한 질병이 영양의 불균형으로 인하여 발생하는 것인가를 알아보기 위하여 이와 관련된 현장에서 사용할 수 있는 간단하고 판독 용이한 간이진단법을 우선 소개하고 영양성 불균형에 기인된 몇 가지 질병들의 원인, 임상증상 및 치료에 관하여 살펴보고자 한다. 또한 급여사료내의 적합한 에너지함량과 조단백함량을 측정하여 영양불균형에 기인한 질병을 예방하는 방안에 대하여 설명 드리고자 한다.

Arthroscopy is a valuable diagnostic and operative tool in equine and human orthopedics. The arthroscope is a difficult instrument to use and requires patience, practice, and persistence in order to obtain good results. This technique was found to be less traumatic than arthrotomy, invasiveness, rapid recovery and the feasibility of surgically correcting many arthropathies. The use of the arthroscope in the dog provides a new dimension in the study and diagnosis of joint derangements. The purpose of this report is to introduce the use of the arthroscope in the dog-more specifically, in the stifle of the dog. A diameter 2.7 mm fore-oblique viewing arthroscope, cold light source, video and video printer are used. With the fore-oblique viewing type it is possible to view directly as well as slightly to the side and the range of viewing can be increased by rotating the arthroscope around the object The scope is connected with a cold light source by means of a fiber-optic light guide. The stifle joint was flexed to 20~30$^{\circ}$. The joint were lavaged with lactated Ringer's solution during arthroscopic examination. Arthroscopy of the stifle was performed prior to arthrotomy in 1 dead dog and 4 healthy dogs, and other 3 dogs was performed only arthroscopic examination. In this study only the conventional approaches were used and in most cases it was possible to view all the intra-articular structures via the lateral infrapatellar approach. In the stifle joint, endoscopic observation was performed to find lateral femoral condyle, patella, medial femoral condyle, trochlear groove, tibia, fat, cranial cruciate ligament, caudal cruciate ligament lateral meniscus, tendon of long digital extensor muscle, medial meniscus, and medial collateral ligament Post-arthroscopic examination, the lameness had disappeared within 12~24 hours. Pain and swelling in the stifle joint had disappeared within 24~36 hours. Post-arthroscopic secondary infection was never encountered in the dogs. In conclusion, arthroscopic insertion technique in canine stifle joint using a diameter 2.7 mm 30$^{\circ}$ arthroscope was established and arthroscopical views of all anatomical structures in the normal stilfe joint were obtained through lateral infrapatellar portal.

전도성 유기물질은 저차원성에 유래한 전자적 거동, 전도기구 및 공학적 응용의 관점으로부터 흥미를 갖게 되어 이 분야의 연구가 현저하게 발전하고 있다. 따라서 본 연구에서는 Langmuir-Blodgett법을 위한 전도성 유기물질 합성의 일환으로 성막물질 합성의 중간체로 이용되는 LiTCNQ를 diethyl succinate를 출발물질로 사용하여 합성한 결과 총수율이 47.5%였다.
