In order to investigate the possible application of ZnO films as a transparent conducting oxide (TCO) electrode for film-typed dye sensitized solar cell(F-DSC), ZnO:Al films were prepared by RF magnetron sputtering method. The effects of gas pressure on the structural and electrical properties of ZnO films were mainly studied experimentally. F-DSC using either a ZnO:Al or indium tin oxide (ITO) electrode were also fabricated separately under the same manufacturing conditions. The electro-optical conversion efficiency and fill factor of the F-DSCs using both ZnO:Al and ITO transparent conducting electrodes were measured and compared with each other. ZnO:Al films showed the minimum resistivity of 2.6 x10^(-3)Ω-cm and a transmittance of 91.7% under the experimental conditions of doping concentration of 2 wt% of Al₂0₃ and gas pressure of 5mTorr. ITO films fabricated at 5mTorr of gas pressure also showed the minimum resistivity of 1.5x10^(-3)Ω-cm and transmittance of 92.1%. Although the electrical resistivity of ZnO:Al is higher than that of ITO, the conversion efficiency of F-DSC using ZnO:Al was comparable with that of F-DSC using ITO. The conversion efficiency of F-DSCs using ZnO:Al and ITO electrodes are about 2.8% and 2.9%, respectively.

In this paper, we studied the method of electrets electrode which formed to accumulate negative electric charges by corona discharges. The breakdown voltage samples and damaged samples by various corona discharges have made material stabilization and improved characteristics of electric charge storage throughout the annealing processes. After the experiment made material stabilization nearly melting point by many kinds of annealing conditions, we did the corona discharge again by the charged high voltages, a discharge electrode gap, and a discharged time. As we compared it with the best condition, we confirmed that characteristics of electric charge storages were improved.

Nine cattle among 18 in a native Korean herd died or were euthanized within 3 days. The affected cattle showed cowshed. The pigs and dogs had been fed leftover food originating from nearby restaurants, and the cattle could presumably reach the contaminated food in the pig troughs. Necropsy revealed a few chicken bones and red pepper pieces as well as large amounts of grain and rice straw hay mixed in the rumen. Botulism type D was isolated in the ruminal contents of one of the cattle. We speculated that the outbreak was associated with the cattle incidentally eating presumably contaminated leftover food from the pig trough.

A case of multicentric high grade T cell lymphoma is reported in a 5-year-old male Maltese dog with generalized lymphadenopathy. The dog showed depression, anorexia, blindness, jaundice, arrhythmia, and hematuria for 8 months. Complete blood count and chemistry profile revealed anemia and increased alanine transferase, alkaline phosphatase, total bilirubin, and total cholesterol. Grossly, most of lymph nodes, spleen, and liver were enlarged and neoplastic masses were occupied in these tissues. Histologically, massive accumulation of small noncleaved neoplastic lymphocytes with high mitotic figures was observed in all lymph nodes and spleen. Infiltration of neoplastic lymphocytes was also noted in the lung, liver, kidney, eye, skin, muscle, and bone marrow of femur. Immunohistochemistry revealed that tumor cells were CD3-positive and but CD79a-negative, consistent with T-cell lineage. In our best knowledge, this is the first report of multicentric lymphoma clarified the origin of tumor cells in Korea.
Cat diseases diagnosed in Korea, 2015~2017

There has recently been a growing demand for pathodiagnosis to determine the cause of death in cats. We retrospectively analyzed the diseases diagnosed in cats that were submitted to Animal and Plant Quarantine Agency (APQA) in 2015~2017. Overall diagnostic rate in feline samples was 85.2% (n=104/122). Among diagnosed cases, infectious diseases (n=63) were responsible for most of the feline diseases and feline panleukopenia (n=29) were most prevalent. Highly pathogenic avian influenza (HPAI) H5N6 was first diagnosed in cats at the end of December 2016 in the HPAI outbreaks. One case in 2015, 4 cases in 2016, and 14 cases in 2017 were associated with animal abuse, such as trauma and poisoning. These results suggest that suitable vaccination of feline infectious diseases, monitoring of the susceptible domestic animals during HPAI outbreaks, and interest on veterinary forensics to prevent and determine animal abuse are needed.
