Purpose In the meantime, there have been not many samples that require dilution, and it has been difficult for the examiner to set an appropriate dilution multiple for RIA test item and report the results. Accordingly, it was judged that it was necessary to set the maximum dilution multiple for each test and to verify the upper limit of the clinical reportable range. Therefore, in this study, the maximum dilution multiple for each RIA test was set and the upper limit of the clinical reportable range was verified accordingly Materials and Methods Among all RIA tests conducted at Asan Medical Center, the study treated on 30 types of tests which also conduct the dilution test. Data from March to July 2021 were collected and analyzed. The study was conducted on samples subjected to serial dilutions such as X2, X4 or X10, X10<sup>2</sup>, X10<sup>3</sup>, X10<sup>4</sup>, X10<sup>5</sup>. Results Among a total of 30 test types, 18 test types have more than 5 N values in the tolerance range of 80~120%. As a result of the verification of maximum dilution multiples, the test set to 10<sup>4</sup> is 𝛼-fetoprotein and thyroglobulin, and the test set to 10<sup>3</sup> is CA-125, CEA, and 𝛽-hCG, and the test set to 10<sup>2</sup> is Free PSA, PSA, CA15-3, SCC, Ferritin, PTH, Cortisol, and Calcitonin. Tests set to 10 include three categories: 𝛽2-Microglobulin, C-peptide, and Testosterone. Conclusion It is expected that it will contribute to improving the quality of nuclear medicine blood tests as the results of dilution experiments can be reported quickly and accurately through the verification of the clinical reportable range.

The purpose of this study was to review the recent 3D graphic rendering techniques that can be used as the lighting visualization simulation tool with a 3D Studio MAX's plug-in renderer. This paper presents photorealistic rendering algorithm the embodies accurate image. In the test rendering simulation, a single prism panel was used to see the prism panel's caustic phenomenon for a directional lights. Based on our comparison, this paper verifies a possibility of the graphic renderers as a lighting simulation tool.

기침이나 콧물은 겨울철의 자연 현상쯤으로 생각하고 더구나 감기 정도는 겁내지 말고 그보다는 아기가 여러가지를 경험하고 새로운 것에 접할 수 있도록 유도하는 것이 현명하다.
