This paper discusses the compressor torque measurement of an automotive air conditioner. A new torque meter has been developed to measure the compressor operating torque, The torque meter consists of three main parts: torque sensor, two telemetry and power supply. The torque sensor has made to measure the strain according to torque. To transmit torque and temperature data from two telemetry to one receiver, Bluetooth network-piconet has been formed. The torque meter was installed in vehicle and the compressor operating torque has been measured during the FTP 75 test. As the result of the torque measurement, the compressor operating power can be calculated by torque and RPM.

Grossly, a lot of soft white nodules, 0.5~1.5 cm in diameter, were randomly scattered in liver of a slaughtered Korean Native Cattle. The surface of liver was roughened by those nodules. Histopathologically the nodules were consisted of numerous mature blood vessels, which had variable size and wall thickness, and which were encircled by much connective tissue. Masson`s trichrome stain clearly revealed the proliferated blood vessels and perivascular stroma and, immunohistochemical staining revealed that endothelial cells of proliferated blood vessels were positive for Von Willebrand Factor. Based on gross and histopathological lesions, and immunohistochemical staining, the case was confirmed as hepatic vascular hamartoma and it is the first case report in Korea, as far as we know.

본 조사 연구는 종란을 생산하는 원종계, 종계, 백세미씨 알 생산 농장을 대상으로 수직 감염(난계대전파)되는 전염성 질병인 추백리/가금티푸스, 닭마이코플라즈마증(MG, MS), 전염성 빈혈증, 조류아데노바이러스 감염증에 대한 항원 및 항체 검사를 실시하였다. 조사 기간은 2009년 8월부터 12월까지 5개월간 원종계 45계군, 종계 1,018계군, 백세미씨알 생산 54계군에 대한 성적이다. 추백리/가금티푸스 항원 검사에서는 모든 계군이 음성으로 확인되었으나, 항체 검사결과 종계 3.2%, 백세미씨알 생산계군 3.0%의 항체 양성율이 관찰되었다. 계종별 가금티푸스의 발생률은 종계군의 항원 검사 결과와 상반되어 육계 44.3.7%, 백세미 26.2%, 산란계 15.7%, 토종닭 12.6%, 육용 종계 1.08%였다. MG 항체 검사 결과, 원종계 71.1%, 종계 및 백세미씨알 생산계군 각 88.7% 항체 양성율이 확인되었으며, MS 항체 검사 결과도 비슷한 수준으로 나타났다. 닭 전염성 빈혈 바이러스 검사 결과, 원종계 42.2%, 종계 18.0%가 바이러스를 갖고 있는 것으로 나타났으며, 항체 양성율도 86% 이상이었다. 이와 함께 조류 아데노바이러스항원검사결과에서는원종계4.4%, 종계2.7%, 백세미씨알 생산계군 9.35%가 바이러스를 보유하고 있는 것으로 조사되었다. 결론적으로 국내 종계군은 닭 마이코플라즈 마증과 닭 전염성 빈혈에 상당히 높은 수준으로 감염되어 있는 것으로 판명되어 질병별 적절한 예방책이 필요한 것으로 나타났다. A survey of transovarially transmitted diseases, including salmonellosis [(pullorum disease; PD)/(fowl typhoid; FT)], mycoplasmosis, avian infectious anemia (CIA), and fowl adenovirus infection was conducted in the breeder chickens from August to December in 2009. The numbers of flocks sampled out were: Grand Parents Stock (GPS), 45; Parents Stock (PS) 1,018, Baeksemi breeder (BSB) 54. The seroprevalence of salmonellosis (PD/FT) were 0% (GPS), 3.2% (PS), and 3% (BSB), respectively. A total of 983 chicken farms were affected with FT outbreaks between 2000 and 2008. The incidence of FT in commercial broilers, Baeksemi, commercial layers, native chickens, and broiler breeders was 44.3%, 26.2%, 15.7%, 12.6% and 1.08%, respectively. Of the affected broilers, over 90% birds were under 2 weeks of age, indicating it was possible that they were infected with S. gallinarum via vertical transmission. The sero-positive flocks against Mycoplasma gallisepticum (MG) were 71.1% (GPS), 88.7% (PS), 88.7% (BSB), while the rates of positive flocks against Mycoplasma synoviae (MS) were 86.0% (GPS), 77.0% (PS), and 98.0% (BSB). In GP and parent farms, the detection rates on specific genes of CIA virus were 19/45 (42.2%), and 169/1039 (18.0%), respectively, whereas the seroprevalence of CIA were 86.0% in GPS and 93.7% in PS flocks. In addition, positive flocks of fowl adenoviruses were 4.4% (GPS), 2.7% (PS) and 9.35% (BSB), respectively. As the results, avian mycoplasmosis and CIA have been more prevailing in chicken breeder than avian salmonellosis and fowl adenovirus infection in Korea.
