Cutaneous Myiasis Associated with Tick Infestations in a Dog
최정구,김한종,나지웅,김성현,박철 한국임상수의학회 2015 한국임상수의학회지 Vol.32 No.5
A 12-year-old intact male, Alaskan Malamute dog, which lives in the countryside, was presented with inflammation and pain around perineal areas. Thorough examination revealed maggots and punched-out round holes lesion around the perineal region. Complete blood counts (CBC) and serum biochemical examinations showed no remarkable findings except mild anemia and mild thrombocytosis. The diagnosis was easily done, based on clinical signs and maggots identification. Cleaning with chlorhexidine, povidone-iodine lavage and hair clipping away from the lesions were performed soon after presentation. SNAP 4Dx Test (IDEXX Laboratories, Westbrook, ME, USA) was performed to rule out other vector-borne diseases since the ticks were found on the clipped area and vector-borne pathogens. The test result was negative. The dog in this case was treated with ivermectin (300 mcg/kg SC) one time. Also, treatments with amoxicillin clavulanate (20 mg/kg PO, BID) was established to prevent secondary bacterial infections. Then, myiasis resolved with 2 weeks and the affected area was healed.

The right paratracheal stripe (RPS) is a band-like water density between air-column of the trachea and the surrounding right lung. The authers have experienced some unexpected diseases and earlier diagnosis made by the right paratracheal stripe, therefore, this study was done to determine the normal range of RPS in Korean by measuring of RPS in 132 normal subjects, 30 pregnant women and 120 pathologic cases. The results obtained are summerized as follows; 1. The normal limit of RPS in Korean was 1-4mm, and it is reguared as abnormal finding when the RPS value exceeds the normal limits. 2. It was less than 2.5mm in 80% of normal adult, and 60% was in between 1.6 to 2.5mm. 3. The RPS of pregnant women was within normal limits, and it was the same tendency in pneumonic subjects. 4. The RPS was increased with the order of pleurisy, primary and metastatic lung cancer, pulmonary tuberculosis subjects.

Since mid 20th century, dental treatments with laser have been introduced and improved a lot. Because early $CO_2$, Nd:YAG, diode, argon, and holmium lasers are used for dealing soft tissue, so it applied just limited field. But, in 1997 the lasers of erbium family that able to dealing soft and hard tissue also were introduced, laser application fields are enlarged. In today, the application fields reach on implantation treatment, so clinicians can use the laser to make holes for implantation, and flap elevation, even though treating peri-implantitis. So our class want to discover the optimal setting of Er:YAG laser when treating peri-implantitis. We observed the surface that initially treated by RBM and TPS passion and laser with varied options of exposure time and power with SEM image. For this we conclude the optimal setting range that does not alter the implant surface structure and report it.

시골에 사는 12년령의 중성화 안한 수컷 말라뮤트가 회음부위의 염증과 통증을 주호소로 내원하였다. 회음부 신체검사에서 구더기와 구멍이 있는 피부 병변이 존재하였다. 혈액검사에서는 미약한 빈혈과 혈소판 증가증 이외에 특이소견은 보이지 않았으며 진단은 임상증상 및 구더기의 존재에 의해 쉽게 되었다. 즉시 삭모 및 소독을 실시하였으며 삭모 중 진드기가 발견되어 SNAP 4DX (IDEXX Laboratories, Westbrook, ME, USA)를 이용해 진드기 및 관련 병원체의 감염유무를 평가하였고 검사결과는 모두 음성이었다. 치료는 이버멕틴(300 mcg/kg)을 피하 주사로 한번 주사하였으며 2차 감염을 예방하기 위해 항생제를 처방하였다. 이 후 구더기증과 상처부위는 2주 이내에 치료되었다.

면외변위의 정량적 계측을 위한 ESPI와 Shearography의 비교
최정구,김경석,장호섭,정성욱 朝鮮大學校 機械技術硏究所 2005 機械技術硏究 Vol.8 No.2
Electronic Speckle Pattern Interfrometry is a common method for measuring out-of-plane displacement and in-plane displacement and applied for vibration analysis and strain/stress analysis. However, ESPI is sensitive to environmental disturbance, which provide the limitation of industrial application. On the other hand, Shearography based on shearing interferometer can directly measure the first derivative of out-of-plane displacement, which is insensitive to vibration disturbance. This paper proposes the out-of-plane displacement extraction technique from results of Shearography by numerical processing and measurement results of ESPI and Shearoraphy are compared quantitatively.
ESPI와 Pulse ESPI를 이용한 모형교량의 거동해석

At present strain gage technique and accelerometer are used widely for the diagnosis safety of constructions. However, the limits of these methods are revealed. But ESPI(Electronic Speckle Pattern Interferometry) and Pulse ESPI is noncontact, whole-field, real-time measuring method. Especially Pulse ESPI method is insensitive to disturbance and can achieve test result in a very short time. It has various strong points in spot application, swift establishment, and dynamic conduct analysis for the entire field of Laser illumination. In this paper a new approach for safety diagnosis on bridges based on speckle interferometry techniques is presented.
