Presently, there is the blind of about 20~300,00 people including didn't register in Korea Usually, they used white stick when they walk outside. There is the blind receiving the help of the guide dog but a small number of blind uses due to many composite problems including the cost problem, and etc. Presently, the guidance service aid long for the blind which is commonly used adheres the RFID tag to the white stick. It remains at the level of the extent of making the cover block and RF communication by using this. The recognition distance is short. This is the actual condition in which it is difficult to determine the location of the clear obstacle and size and form, it doesn't become the help which is actually big in the walk of the blinds. Thus, in this paper, the investigation of 'Smart Portable Navigation System' development of the Cortex-A8 Platform base tries to be handled so that the blinds can walk easily.

5 year-old female Siberian husky which was 27 kg had presented with a recurrent rhinitis with chronic discharge and cough. A nasal foreign material had been suggested by a finding of a bone density ($0.3{\times}0.3$ cm) in the left nasal cavity on X-ray and CT-scanning. Soft tissue opacity in frontal sinus and nasal cavity was increased and foreign material was located beside turbinate bone in the left nasal. We found that there was the increase in the number of eosinophil and mast cell by the nasal cytology test. These results mentioned above indicated that the rhinitis by nasal foreign body was suspicious. We decided that the transfrontal rhinotomy could be the proper procedure to approach the material in this case. After rhinotomy, the foreign body and severe sticky discharge were removed. Drain was placed through the hole and into the frontal sinus and nasal cavity which were flushed two times a day for 7 days. The clinical signs such as cough and nasal discharge were shown to be improved in the every visiting for the re-check. On the $40^{th}$ day after surgery, we could confirm that the most of soft tissue density in the frontal sinus and nasal cavity was decreased by CT-scanning. However, foreign body was not identified by histological examination. For the treatment of chronic rhinitis caused by foreign body, the surgical method such as rhinotomy can be applied, when it is difficult to remove it in the guide of the nasal endoscope.

In this study, a meta-analysis of fecal bacteria in dogs was conducted using 16S rRNA gene sequences that have been recovered from cloning and Sanger sequencing. For this meta-analysis, we retrieved all 16S rRNA gene sequences recovered from fecal bacteria in dogs in the RDP database (Release 11, Update 3). A total of 420 sequences were identified from the RDP database, 42 of which were also recovered from cultured isolates. The 420 sequences were assigned to five phyla, of which Firmicutes was the most predominant phylum, accounting for 55.2% of all 420 sequences. Bacteroidetes was the second most predominant phylum, accounting for 32.1% of the 420 sequences, followed by Actinobacteria (6.4%), Fusobacteria (3.8%), and Proteobacteria (2.4%). The genus Bacteroides within Bacteroidetes was the largest, representing 30.0% of all 420 sequences, while the putative genus Clostridium XI within Firmicutes was the second largest, representing 27.4% of all 420 sequences. A total of 82 operational taxonomic units (OTUs) that are putative species were identified from the retrieved sequences. The results of this study will improve understanding of the diversity of fecal bacteria in dogs and guide future studies on the health and well-being of dogs.

The purpose of this study was to explore the components of the geriatric robot pet, which might be helpful in caring for elderly people in the future. Focus group interview-with two focus groups-was performed between August 2014 and December 2014. Study participants were 13 geriatric experts from nursing, medicine, social work, and physical/occupational therapy. All interview data were transcribed, followed by debriefing and a qualitative content analysis. Three main themes emerged: acknowledgment of the usefulness of geriatric robot pet, establishment of elderly-centered appearance, and the functions of the robot pet to meet the needs of elders and family members. The robot pet was considered to be useful to elders who live alone since they can benefit from companionship and care provided by the robot pet. Geriatric robot pet needs to be manageable in size and weight, like a small dog. Moreover, a function that allows for interaction with and monitoring the elderly would be beneficial. The baseline elements that could guide further development of contents for the Korean geriatric robot pet were proposed from the results of FGI. Studies that validate these elements are necessary.

Working dogs, such as rescue dogs, military watch dogs, guide dogs, and search dogs, are selected by in-training examination of desired traits, including concentration, possessiveness, and boldness. In recent years, genetic information has been considered to be an important factor for the outstanding abilities of working dogs. To characterize the molecular features of the canine genes related to phenotypes for working dogs, we investigated the 24 previously reported genes (AR, BDNF, DAT, DBH, DGCR2, DRD4, MAOA, MAOB, SLC6A4, TH, TPH2, IFT88, KCNA3, TBR2, TRKB, ACE, GNB1, MSTN, PLCL1, SLC25A22, WFIKKN2, APOE, GRIN2B, and PIK3CG) that were categorized to personality, olfactory sense, and athletic/learning ability. We analyzed the chromosomal location, gene-gene interactions, Gene Ontology, and expression patterns of these genes using bioinformatic tools. In addition, variable numbers of tandem repeat (VNTR) or microsatellite (MS) polymorphism in the AR, MAOA, MAOB, TH, DAT, DBH, and DRD4 genes were reviewed. Taken together, we suggest that the genetic background of the canine genes associated with various working dog behaviors and skill performance attributes could be used for proper selection of superior working dogs.

Background: Positive end, expiratory pressure (PEEP) has become one of the standard therapies for adult respiratory distress syndrome (ARDS). Total static compliance has been proposed as a guide to determine the size of PEEP ('best PEEP') which is of unproven clinical benefit and remains controversial. Besides increasing functional residual capacity and thus improving oxygenation, PEEP stimulate prostacyclin secretion and was proposed for the treatment of acute pulmonary embolism. But little is known about the effect of PEEP on hemodynamic and gas exchange disturbances in acute pulmonary embolism. Methods: To study the validity of total static compliance as a predictor of 'best PEEP' in ARDS and acute pulmonary embolism, experimental ARDS was induced in mongrel dog with oleic acid and acute pulmonary embolism with autologous blood clot. Then hemodynamic and gas exchange parameters were measured with serial increment of PEEP. Results:In ARDS group, total static compliance and oxygen transport were maximal at 5 cm$H_2O$, and decreased thereafter (p<0.05). With increment of PEEP, arterial oxygen tension ($PaO_2$) and arterial carbon dioxide tension ($PaCO_2$) increased and cardiac output and physiological shunt decreased. In pulmonary embolism group, total static compliance, oxygen transport, physiological shunt and cardiac output decreased and $PaO_2$ and $PaCO_2$ increased with increment of PEEP (p<0.05). Comparing the change induced by increment of PEEP by 1 cm$H_2O$ in ARDS group with that in pulmonary embolism group, there was no significant difference between two groups except cardiac output which decreased more in pulmonary embolism group (p<0.05). In ARDS group, oxygen transport and total static compliance increased after PEEP application, and total static compliance was maximal at the PEEP level where oxygen transport was maximal. However in pulmonary embolism group, oxygen transport and total static compliance decreased after application of PEEP. There was significant correlation between change of total static compliance and change of oxygen transport in both groups. Conclusion: In both ARDS and acute pulmonary embolism, it can be concluded that total static compliance is useful as a predictor of 'best PEEP'.
