A 7-year-old male castrated Shih-tzu dog was referred to the Veterinary Medical Teaching Hospital of Chungnam National University for severe pruritus. On physical examination were confirmed systemic erythema and alopecia, crust on the neck and flank region. Tape strip test identified numerous degenerative neutrophils and severe Malassezia infection. Treatment for severe pruritus was applied with systemic antihistamine therapy and topical therapy with antimicrobial shampoos. For the finding of appropriate treatment of atopic dermatitis, it was chosen six immune-related treatments. And clinical sign scores were evaluated by investigator with CADESI-03 after each application of six treatments. Application of human immunoglobulin G and leflunomide showed the remarkable regression of lesions.

설악산국립공원 설악폭포에 위치한 아고산대 침엽수인 분비나무와 잣나무의 수고생장 기간을 조사하기 위해 본 연구를 수행하였다. 조사를 위해 분비나무 고사목 2본(SAPPAND01, 02)과 잣나무 고사목 1본(SAPPPKD03)을 선발하였다. 높이별 수고생장 기간을 조사하기 위해 뿌리와 줄기 경계를 기준으로 높이 0, 10, 20, 30, 40, 50, 60, 80, 100 cm에서 디스크를 채취하여 나이테(이하, 연륜) 분석을 실시하였다. 또한 고사연도 분석을 위해 생육중인 분비나무 15본에서 생장편을 채취하여, 연구지를 대표하는 연륜폭연대기를 작성하였다. 연륜 분석 결과, 분비나무인 SAPPAND01과 02의 생육 기간은 각각 102년(1915-2016)과 97년(1918-2014)이었으며, 잣나무인 SAPPPKD03은 62년(1926-1987)이었다. SAPPAND01과 02의 고사 시기는 각각 2016년 가을-2017년 봄과 2015년 여름-가을이었으며, SAPPPKD03의 고사 시기는 1987년 가을-1988년 봄이었다. 100 cm까지 수고생장을 하는데 소요되는 기간은 SAPPAND01이 41년으로 가장 길었으며, SAPPAND02와 SAPPPKD03은 각각 17년과 18년으로 조사되어 수종보다는 개체 간 차이가 큰 것으로 확인되었다. 하지만, 대상목 모두에서 수고 20 cm 전후까지 생장하는데 소요되는 기간은 공통적으로 긴 것으로 나타났다. 본 결과는 향후 우리나라 아고산대 침엽수 수령조사의 정확성을 향상 시키는데 중요한 기초자료가 될 것이다. This study aimed at investigating the height-growth duration of Abies nephrolepis and Pinus koraiensis which are the tree species growing in the subalpine area at Seorak Falls of the Seoraksan National Park. For the study, two dead Abies nephrolepis (SAPPAND01, 02) and one dead Pinus koraiensis were selected. To investigate the height-growth duration, 9 disks were collected at the height of 0, 10, 20, 30, 40, 50, 60, 80, 100 cm height from the collar to upward from the sample trees, and then their ring-width were measured. The site master chronology used to the reference to date the death years of the sampled trees was established using the increment cores from 15 living Abies nephrolepis. Through the tree-ring analysis, the ages of SAPPAND01 and 02, and SAPPPKD03 were verified 102 (1915-2016), 97 (1918-2014), and 62 years (1926-1987) years, respectively. The death seasons and years of SAPPAND01 and 02, and SAPPPKD03 were autumn in 2016 - spring in 2017, summer - autumn in 2015, and autumn in 1987 and spring in 1988, respectively. The height-growth durations up to 100 cm from the collars of SAPPAND01 and 02 and SAPPPKD03 were -41, 17, and 18 years, respectively, so that it was verified that the height-growth duration was not changing depending on tree species but individual trees. During the juvenile periods growing up to approximately 20 cm from the collar, however, all sample trees showed relatively taking long times. All results obtained from this study would be fundamental data to improve the accuracy of examining the age of conifers in the subalpine areas.

The current study was conducted to investigate (1) the duration of cambial activity and (2) the effect of degree days on the initiation of cambial activity of the Pinus koraiensis (PK) and Chamaecy- paris picifera (CP) planted in Mt. Worak. In addition, the differences of the seasonal cambial activities according to the diameter were also investigated using C. picifera with a diameter of 30 cm (CPL) and 15 cm (CPS), which were planted in the same year. The cambium samples were weekly collected using a mini-borer (Ø 2 mm), so called Traphor, between April and October in 2017. The results obtained are as follow. The initiation of the cambial activity of CP (April 21-28) were slightly earlier than PK (April 21). The species with the longest cambial activity was CPS (147.2±12.1 days), followed by PK (141.6±9.8 days) and CPL (139±12.1 days). The degree days inducing the initiation of the cambial activ- ity for PK and CP were 180.5 and 180.5-242.8, respectively.

The dependence of electrostatic force on applied voltage, temperature and humidity was investigated. In addition, response characteristics on applied voltage and relationship between electrical resistivity and electrostatic force characteristics such as Coulomb force and Johnsen-Rahbeck force were discussed

A 5-year-old Russian blue cat was referred to the Veterinary Medical Teaching Hospital of Chungnam National University with the history of anorexia, lethargy, weight loss(6.5 to 4.8 kg) 2 weeks ago. Abdominal ultrasonography showed the following : increase of echogenicity of liver, irregular shape of gall bladder, hyperechoic region around duodenum. Pancreatitis, cholangitis, hepatic lipidosis was diagnosed by the ultrasonography. Anti- inflammatory therapy, antibiotic therapy was administered. Abdominal ultrasonography is a efficient available diagnostic tool but serum fPL test reveals the highest sensitivity and specifity result for feline pancreatitis. SNAP fPL test is newly released that can check pancreatitis within 10 minutes by same princple of Spec fPL test used in Gastrointestinal Laboratory of Texas A & M Univerrsity.

A 4 years old, mixed male dog with a history of traffic accident was presented to the Veterinary Medical Teaching Hospital of Chungnam National University with tachypnea and respiratory distress. Physical examination showed that the dog was auscultated crackles sounds, dysynchronous abdominal breathing pattern, hemoptysis, hematuria, urodynia and right and left scleral congestion. Blood and blood chemical examination revealed that WBC, AST and ALT was highly elevated. Parenchymal pulmonary fluid and closed pneumothorax were observed by thoracic radiography. This case was diagnosed as pulmonary contusion. Intravenous fluid and oxygen was administered and also dexamethasone(1mg/kg, Ⅳ), furosemide(2mg/kg, Ⅳ), (ampicillin, 20mg/kg, Ⅳ) and meloxicam(0.2mg/kg, PO) were intravenously injected for 5 days. Abnormal clinical signs were disappeared after treatment.

자동차의 air-bag 장치에 실용될 수 있는 압저항형 단결정 실리콘 가속도센서 칩을 개발하기 위하여 결정 실리콘 미세구조의 제조방법을 확립하고, 단위공정의 검증을 통하여 일괄공정에 의한 PROTO-TYPE 칩을 만드는 기술을 연구하였다. 단결정 실리콘 미세구조는 선택확산법을 이용하여 정확히 선택된 영역에만 air-gap을 형성하여 미세구조의 측면식각을 방지하는 선택확산법에 의한 실리콘 마이크로머시닝 기술로 제조하였다. 일괄공정을 위한 단위공정확립을 위하여 PROTY-TYPE 8빔 브릿지형 가속도 센서를 제조하였다. 제조된 칩의 가속도에 따른 출력전압은 선형성을 나타내고 있으며, 감도는 약 50 ㎶/V·g로 나타났다. 이 감도는 50G용 가속도센서의 사양을 만족하지 못했다. 이는 공정에 의한 문제라기 보다는 가속도센서의 시뮬레이션에 의해 설계한 구조가 이미 원하는 감도에 못 미친다는 것으로 생각된다. 따라서 2차 공정으로 제조될 가속도센서의 파라미터를 SuperSAP 유한요소 패키지를 이용하여 실리콘 미세구조부의 파라미터에 따른 특성을 시뮬레이션하였다. 설계된 50G용 가속도센서의 mass Pad의 반경 및 빔 길이, 빔 폭, 빔 두께, 그리고 mass의 각 파라미터 값은 700 ㎛, 120 ㎛, 5 ㎛, 1.0 ㎎ 이었다. 반도체 공정기술, 관성질량 제조법 및 선택확산을 이용한 마이크로머시닝을 사용하여 일괄공정으로 8빔 브린지형 가속도센서를 제조하였다. We researched the establishment of the silicon microstructure fabrication technique to develop a piezoresistive type silicon acceleration sensor chip and the technique to make a proto-type chip by the verification of the unit-process. Silicon microstructure is fabricated silicon micro-machining by selective diffusion method. This method prevent a side-etching of microstructure because selective diffused region is only formed an air-gap. We fabricated a proto-type 8-beam bridge-type acceleration sensor to establish the unit-process for the batch-process. The output voltage of the chip represented linearity with acceleration, and the sensitivity was about 50 ㎶/V·g. But this sensitivity dosen't satisfy the requirements of a practical acceleration sensor. The cause of this result is assumed not process problem, but the structure designed by simulation isn't suitable already. Threfore, the characteristics of parameters of the acceleration sensor that will be fabricated by 2nd-process is simulated by SuperSAP finite-element package. The determined parameter values of beam length, beam width, beam thickness, mass, and mass radius are 120 ㎛, 5 ㎛, 1.0 ㎎, and 700 ㎛, respectively. We fabricated 8-beam bridge-type acceleration sensor by batch-process using a semiconductor process technique, proof-mass fabrication method, and micromachinig using selective diffusion.
