Consumer demand for PropTech industries that combine IT technology and real estate industries is increasing. PropTech is growing in various industries related to real estate, such as real estate valuation, data provision, and real estate transactions. In particular, as real estate information acquisition through the platform is expected to become active and transactions are expected, the prop-tech industry is expected to be incorporated in the real estate brokerage industry. At this point, this study aims to find out how the growth of the prop-tech industry changes in the real estate market and how it affects the practical use of the real estate brokerage industry. In this study, we investigated whether the real estate big data platform actually helps brokers improve their expertise in the field, increase customer reliability, and increase profitability by improving competitiveness, and analyzed various measurement items and structural equations. The structural model between latent variables created based on the confirmation factor analysis model was analyzed. As a result of the analysis, it was found that the real estate big data platform had a positive effect on the real estate market for the expertise, reliability, and profitability of the real estate brokerage among the changes in the perception of the real estate broker. On the other hand, it was found that it would negatively affect the competitiveness of the authorized brokerage business. Although PropTech was generally recognized to have a positive effect on the development of the licensed real estate agent, it suggests that the role of licensed real estate agents is needed to strengthen competitiveness.

Targeted radionuclides treatment (TRT) requires the establishment of treatment plans that consider various factors, such as the type of radionuclides, target organs, and administration methods. For this reason, in this study, the absorption dose of a single cell was analyzed according to the type of radioisotope used to treat target radionuclides. In this study, a simulation was performed on beta rays used in the treatment of target radionuclides at the cell level using MCNPX (ver. 2.5.0). First, according to the calculation formula, the beam path according to the type of radioisotope for treatment was calculated. Second, the amount of self-radiation by beta rays emitted from cell diameters of 5 μm and 10 μm cell nuclei was evaluated. As a result, it showed a high range proportional to the maximum energy of the beta-ray, and the highest self-dose distribution from 177 Lu radiation sources among therapeutic radioisotopes. This was analyzed as a result that is inversely proportional to the maximum energy of the beta-ray, and it suggests that the selection of a nuclide considering the range of the beta-ray is necessary in the treatment of target radionuclides in the future.

A fourteen-month-old intact female Poodle was referred to the Veterinary Teaching Hospital, College of Veterinary Medicine, Chungnam National University. The patient was presented with history of vomiting, inappetence, ataxia, insomnia, tachypnea and convulsion for 5 days. Biochemical examination revealed BUN (254.2 mg/dl), creatinine (9.22 mg/dl) and phosphate (14 mg/dl). Epithelial cells of urinary tract, neutrophils, macrophages, a large number of gram negative and smaller number of gram positive bacteria were presented on urine test. Ultrasonographic findings show hyperechogenic kidney and indistinguishableness of renal cortex and medulla. Based on the results of examination described above, this case was diagnosed as acute renal failure with interstitial nephritis by urinary tract infection (UTI). Treatments with fluids therapy, diuretics, and peritoneal dialysis during hospitalization showed good results with no clinical signs.

A 9 months intact male American bull dog with chief complaints of dry cough, dyspnea and fever was referred to the Veterinary Teaching Hospital, Chungnam National University. Based on the findings of physical examination, radiological examination, and blood and blood chemical examinations, the present patient was diagnosed into pulmonary edema secondary to primary bacterial and aspiration pneumonia. The patient was hospitalized and treated with buscopan, cephazolin and furosemide for 1 week. His activity and appetite was returned to normal and thoracic radiographs revealed that Jung was recovered to the normal condition after treatment for 7 days. The present patient was a case with pulmonary edema showed favorable therapeutic responses to proper medication.

A 4-years old pointer dog was referred to the Veterinary Teaching Hospital of Chungnam National University with chief compliment of anorexia, exercise intolerance, hemoptysis, coughing and ascites. It was diagnosed as heartworm disease (class 3) by physical and laboratory examination, radiography, ultrasonography and electrocardiography. This dog was undertaken by adulticidal therapy. Normal conditions and good appetite after therapy were observed.
