  • The Tsushima leopard cat, Prionailurus bengalensis euptilurus, a small felid, inhabits only the Tsushima Islands in Japan. Previous studies of the Tsushima leopard cat revealed that natural factors; including sex, reproductive activity, season, and prey distribution and abundance affect leopard cat home range variation and habitat use. In this study, we focused on clarifying how anthropogenic factors influenced home range variation and habitat use of a male Tsushima leopard cat living near a suburban area in January, March, May and September 2005 using radio-tracking. The home range size (100% MCP) of this cat was $0.78\;{\pm}\;0.26\;km^2$ (mean ${\pm}$ SD, n = 4 tracking sessions) across the whole study period. However, the cat did not use all parts of its home range uniformly; rather it used some habitat types selectively. The cat avoided agriculture areas and residential areas in all of the tracking-sessions. On the other hand, the cat showed a weak preference for artificial structures and a strong preference for baiting sites in January and March, while it avoided them in May, and no baiting site was included in its home range in September. These results suggest that anthropogenic factors influenced the ranging patterns and habitat use of the leopard cat living near a suburban area. Artificial structures might provided good resting spaces for the cat in bad weather. When the density of its main prey was low in the winter, the cat tended to rely on artificial prey and had a small home range size.

  • The nucleotide sequence of Xbal-Mbol fragment of pKH7, a chloramphenicol-resistant($Cm^{r}$) plasmid isolated from multidrug-resistant S. aureus SA2, has been determined. Xbal-Mbol fragment of pKH7 was found to contain two ORFs. One ORF encoded Rap and the other encoded CAT protein. The deduced amino acid sequences of Rep and CAT of pKH7 were compared to those of pUB112 and pC221. Comparisons revealed that there was one amino acid difference in CAT between pKH7 and pUB112. CAT of pKH7 exhibited 98.6% amino acid identity to that of pC221. In case of Rep proteins, a slightly lower homology of 96.4% and 86.7% in amino acid sequences was observed between pKH7 and pUB112 and between pKH7 and pC221, respectively.

  • EtherCAT is an Ethernet-based fieldbus system standardized in IEC 61158 and SEMI, and widely used in the fields of factory automation, semiconductor equipment and robotics. In this paper, we summarize the current status of Xenomai real-time framework and RTnet, which are essential for Linux operating systems to operate in real-time, and implement a real-time EtherCAT master system with these open sources. The real-time performance of the implemented EtherCAT master is evaluated according to Intel network controllers 82574L, I219, I210, and I225, respectively. The results show that the implemented EtherCAT master provides precise control performance for control frequencies from 1KHz to 8KHz and similar performance for I219, I210, and I225, and relatively slightly larger jitter for 82574L.

  • The transgene, pFV4CAT, containing CAT reporter gene regulated by carp $\beta$-actin promoter, was expressed in independent transgenic mud loach germ lines, determined by reverse transcriptase-PCR (RT-PCR) and enzyme-linked immunosorbant assay (ELISA). Expression of the transmitted transgene was found to be tissue-specific in F1 and F2 generations. Tissue specificity of the expression was dependent on each transgenic line with reproducible patterns. Liver and spleen did express the transgene more frequently than other tissues tested, and muscle and heart revealed the higher amount of CAT than other tissues, while testes showed the lowest expression level. The highest level of CAT expression in muscle from a transgenic F1 line was corresponding to 68-fold compared to the basal levels of controls.

  • Semen cryopreservation induces the formation of reactive oxygen species (ROS), and the ROS cause sperm damage. We aimed to investigate the effects of the antioxidative enzyme catalase (CAT) on sperm quality and ROS during cryopreservation. Sperm rich fractions collected from five Duroc boars were cryopreserved in freezing extender with (200 or 400 U/mL) or without CAT (control). After thawing, sperm motility, viability, normal morphology, plasma membrane integrity, mitochondrial function and intracellular ROS were evaluated. CAT significantly improved total sperm motility at a concentration of 400 U/mL (P < 0.05), but didn't improve progressive sperm motility, viability, morphological defects, plasma membrane integrity and mitochondrial function in frozen-thawed boar sperm. In evaluation of ROS, CAT had no effect on reduction in ${\cdot}O_2$, but scavenged $H_2O_2$ in viable frozen-thawed boar sperm at concentrations of 200 and 400 U/mL (P < 0.05). In conclusion, CAT was not enough to improve quality of frozen-thawed sperm, but can reduce $H_2O_2$ generation in viable boar sperm during cryopreservation.

  • A 5-year-old neutered male domestic short-haired cat presented with acute dyspnea characterized by open-mouth breathing and stridor for 2 days. Direct visualization via laryngoscopy revealed diffuse laryngeal swelling and severe thickening of the vocal folds bilaterally; thus, the upper respiratory tract was obstructed owing to severe edema. Neutrophil infiltration was found on fine needle aspiration of the larynx cytology, and no discrete mass with polyp or neoplasia was identified on diagnostic imaging. The cat was diagnosed with acute obstructive laryngitis, and a tracheostomy tube was immediately installed. After 17 days of treatment with steroids, doxycycline and azithromycin, the swollen larynx gradually improved, and there was no recurrence of laryngitis or respiratory obstruction. A feline upper respiratory polymerase chain reaction panel revealed Mycoplasma felis infection; however, it could not be determined whether it was pathogenic or opportunistic. Herein, we report a case of obstructive laryngitis in a cat. When respiratory obstruction due to acute laryngitis is identified, a good prognosis is expected with rapid and appropriate treatment.

  • Industrial network, often referred to as fieldbus, becomes an indispensable component for intelligent manufacturing systems. Thus, in order to satisfy the real-time requirements of field devices such as sensors, actuators, and controllers, numerous fieldbus protocols have been developed. But, the application of fieldbus has been limited due to the high cost of hardware and the difficulty in interfacing with multi-vendor products. As an alternative to fieldbus, the Ethernet (IEEE 802.3) technology is being adapted to the industrial environment. However, the crucial technical obstacle of Ethernet is its non-deterministic behavior that cannot satisfy the real-time requirements. Recently, the EtherCAT protocol becomes a very promising alternative for real-time industrial application due to the elimination of uncertainties in Ethernet. This paper focuses on the implementation of the IEC 61800 based real-time EtherCAT network for multi-axis smart driver. To demonstrate the feasibility of the implemented EtherCAT slave module, its synchronization performance is evaluated on the experimental EtherCAT testbed with a single axis smart driver.

  • Purpose: The nasal bone fracture is the most common type of facial bone fracture. In making a diagnosis, physical findings are much more important than the simple radiologic findings. Facial bone CAT scan can provide the accurate diagnosis and the correct location of nasal bone fractures, so it can be lessoned with proper intervention. The aim of this study was to evaluate the usefulness of facial bone CAT scan in the diagnosis of nasal bone fractures. Methods: The medical records and facial bone CAT scan of 45 patients clinically suspected nasal bone fracture but was not diagnosed on simple radiologic findings were analyzed. Results: All of the 45 patients were confirmed as nasal bone fractures in the facial bone CAT scan. The most common cause of fracture was assault. The mean age was 23.2 years. Physical findings were tenderness (100%), swelling(93.3%), epistaxis(66.6%), deviation (42.2 %), external wound(17.7%) and crepitus(4.4%) in order. Conclusions: It was concluded that the simple radiologic findings can not be conclusive, where the physical findings indicate a suspected nasal bone fracture. The facial bone CAT scan was more reliable for the correct diagnosis and follow-on treatment.

  • This study aimed to analyze water cycle at Taehwa river, Dongcheon, Hoiya river and Cheongryang cheon in Ulsan city using CAT model developed by Korea Institute of construction technology. To apply CAT model, we separated Teahwa river into 25, Dongcheon into 11, Hoiya river into 17 and Cheongryangcheon into 5 subbasins and discriminated between contribution runoff basins and source basins. The results of water cycle analysis performed using rainfall datas measured from 1975 and 2008 and hydrologic datas of change of land use etc. were that surface runoff increase and interflow decrease, caused by the increase of impervious area. The increases of surface runoff at the basin of Taehwa river and Dongcheon which is a tributary of Taehwa river were small and similar to each other respectively as 1.7% and 2.4%, and increased high rate of 3.2% and 7.7% in Hoiya river and Cheongryangcheon including subbasins which are having high rate of urbanization.
