  • A 170 kg, 9-year-old, female Asian black bear was presented for sterilization. Physical examination revealed no evidence of any abnormal clinical sign. Laparoscopic salpingectomy was performed for sterilization. A $25^{\circ}$ laparoscope was inserted in the first port, 1-cm caudal to the umbilical scar, to view the abdominal cavity. Two more ports were made 15 cm caudo-lateral to the first port bilaterally. An atraumatic grasper and a vessel-sealing device were inserted in the bilateral ports. The vessel-sealing device was used to seal and cut the fallopian tube and mesosalpinx. There was no sign of hemorrhage on the severed ends of the fallopian tube and mesosalpinx. At 4 weeks, no physical, behavioral, or other assessable impairment was found. This is the first case report in an Asian black bear to describe laparoscopic salpingectomy for sterilization.

  • Bear bile has been used as a therapeutic for cerebral and coronary thrombosis, convulsion, hepatitis, jaundice, and abscess in traditional oriental medicine. In recent decades, the effects of bile acids on cancer, cholestasis, and liver injury have been investigated in many studies. In this study, we investigated the anti-inflammatory effects of whole bear bile (WBB) and its two major components, chenodeoxycholic acid (CDCA) and ursodeoxycholic acid (UDCA), on rectal inflammation in rats. Bile acids in WBB were quantitatively analyzed by HPLC. Rectal inflammation was induced in male Sprague-Dawley rats by insertion of croton oil-saturated cotton tips. WBB, UDCA or CDCA solution was orally administered to rats one hour after induction of rectal inflammation. Rats were sacrificed 4 or 24 hours after induction of rectal inflammation. The evaluation included measurement of weight and thickness of rectum and histopathologic examination of rectal tissue. Furthermore, we examined the inhibitory effect of WBB, UDCA or CDCA against NO production in LPS-stimulated RAW 264.7 cells. The contents of UDCA and CDCA in WBB were $39.26{\mu}g/mg$ and $47.11{\mu}g/mg$, respectively. WBB treatment significantly reduced the weight and thickness of rectum compared with UDCA or CDCA treatment. The inhibition of NO production by WBB, UDCA and CDCA in LPS-stimulated RAW 264.7 cells was much higher than that by the control. And, WBB treatment suppressed the induction of NO synthase in rectum homogenates. These results suggest that the anti-inflammatory effect of WBB is related to the suppression of NO synthase induction and the inhibition of NO production by UDCA, CDCA and other bile acids of WBB.

  • KASI and Seoul National University developed the Fast Imaging Solar Spectrograph (FISS) as one of major scientific instruments for the 1.6 m New Solar Telescope (NST) and installed it in the Coude room of the NST at Big Bear Solar Observatory (BBSO) in May, 2010. The major objective of the FISS is to study the fine-scale structures and dynamics of plasma in the photosphere and chromosphere. To achieve it, the FISS is required to take data with a spectral resolution higher than $10^5$ at the spectrograph mode and a temporal resolution less than 10 seconds at the imaging mode. The FISS is a spectrograph using Echelle grating and has characteristics that can observe dual bands (H${\alpha}$ and CaII 8542) simultaneously and perform fast imaging using fast raster scan and two fast CCD cameras. In this paper, we introduce briefly the whole process of FISS development from the requirement analysis to the first observations.

  • In almost all previous hydrological studies, the standard approach adopted for nonlinear time series analysis is to perform system characterization first followed by forecasting. However, a practical inverse approach for forecasting nonlinear hydrological time series was proposed recently To investigate the applicability standard approach method and inverse approach, this study used a theoretical time series (Mackey-Glass time series) and daily streamflows of the Bear River in Idaho. To predict a theoretical time series and daily streamflow, this study used local approximation method. From chaos analysis, chaotic characteristics are found in daily streamflow of the Bear River in Idaho. Resulting from 1, 3 and 5-day prediction, inverse approach method is shown to be better than the standard approach for a theoretical chaotic time series and daily streamflow.

  • The purpose of this paper is to analyze the composition of the arbitration costs in ICC Rule of Arbitration and to examine how each item of the costs is determined. Furthermore this author tired to find the principles or criteria deciding which of the party should bear them or in what proportion they shall be home by the parties in Article 31. Thus this author could find three common approaches. First, all of the costs are home by the losing party, or Second, all of the costs are allocated in proportion to the result of award in each case. Third, all of the costs determined by the Court as shared equally by the parties and both parties bear their own costs. But, both parties may include their intention in accordance with the principle of party autonomy. For example if the parties with to ensure that the arbitration costs be shared equally and that the arbitrator make no allocation of costs and fees, the following sentence could be added to the arbitration clause. "All costs and expenses of the arbitrators (and the arbitral institution) shall be home by the parties equally; each party shall bear the costs and expenses, including attorneys' fees, of its own counsel, experts, witnesses and preparation and presentation of its case."

  • Shocks are thought to be important in the dynamics and heating of the solar chromosphere. The observational determination of shock parameters, however, has been hardly done because of the difficulty of observation at a high spatial, temporal and spectral resolution, and the lack of an effective method of inferring physical parameters from spectral data. Our inversion of the spectral data of the $H{\alpha}$ and Ca II 854.2 nm lines simultaneously taken from an intranetwork area, produced temporal profiles of temperature as well as line-of-sight velocities, from which we infer that three-minute chromospheric oscillations prevailing in the upper chromosphere are in fact trains of strong shocks with a strength of about two and a propagation speed of 20 km s-1 that carry a mechanical energy flux of 500 W m-2 upward. Our result supports the notion that shocks dominate the heating of the upper chromosphere, and probably the corona as well, at least in intranetwork regions of the quiet sun.

  • An example of lymphoblastic lymphosarcoma was diagnosed in a 7-year-old male brown bear (Ursus arctos) that died after having a 7-month history of depression, anorexia and watery diarrhea. Grossly the mesenteric lymph nodes were enlarged to approximately 4 to 6 times their normal size and histologically diagnosed as lymphoblastic lymphosarcoma. The small intestinal mucosa was corrugated and had severe mural thickening due to infiltrated neoplastic cells. Hepatic metastasis was also noted. the mother of this bear which died at the age of 20 also had similar gross changes on necropsy, but histological examination was not performed at that time and therefore the exact type of neoplasm remained to be determined. Since the daughter also died of neoplasm, genetic factor could be suspected in this family. This is the first reported case of lymphosarcoma in Ursidae in Korea. As an incidental finding, endogenous lipid pneumonia was noted in the lung.

  • Objective : This study developed species-specific PCR and PCR-RFLP to detect the adulteration of Fel ursi products with cattle and pig bile juices. Methods : All the primers for PCR and PCR-RFLP in this study were designed based on nucleotide sequences of cytochrome b genes in the mitochondria. Results : The species-specific PCR amplified a DNA fragment of 214, 214, 295, and 167 bp from Fel ursi product, bear fur, cattle bile juice, and pig bile juice, respectively. The survey using the speciesspecific PCR indicated that some of commercial Fel ursi products were adulterated with cattle and pig bile juices. PCR-RFLP using the restriction endonucleases, HaeIII and HinfI enabled differentiation among Fel ursi product, cattle bile juice, and pig bile juice. Bear furs from two animals showed variations in PCR-RFLP patterns with HaeIII. Discussion : The detection methods of the species-specific PCR and PCR-RFLP could be useful in eliminating adulterated Fel ursi products from the market.
