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.

본 연구의 사면도 스케치에 의한 조형적 아이디어 정리 과정은 디지털 모델링상에서 디자이너의 추상적 입체 이미지를 보다 효율적이고 객관적으로 정의할 수 있는 방법을 모색하는 것이다. 특히, 복합곡면을 이루는 자동차 디자인은 모든 아이디어의 결과가 삼차원 조형으로 표현되기 때문에 아이디어를 구체화하는 과정의 이해와 조형을 분석하는 능력이 요구된다. 그러나 상상 속의 조형적 이미지를 디지털 삼차원으로 명확하게 정의하는 일은 결코 쉬운 일이 아니다. 이에 따라 사진의 의도와는 전혀 다른 조형을 만들거나, 세부적인 면 해석이 불분명한 조형이 되기 쉽다. 이는 분석적인 조형능력이 디지털 모델의 제작과정 숙지와 장비 활용만으로는 그 실체적 본질에 접근하기 어렵기 때문이다. 따라서 본 연구에서는 이태리 카로제리아의 디지털 프로세스 사례를 중심으로 절차상 특성과 사면도에 의한 아이디어 정리방법을 분석하여 자동차디자인을 배우는 학생들이 보다 체례적인 조형 분석을 할 수 있는 지침을 마련하는데 있다. The ideation process by 4view drawing sketches in this study is to define abstract solid images and make digital three-dimensional modeling in more efficient and objective way. And it is necessary to understand this ideation process and analyze shaping composition, especially in car design, since it is made of complex curved surfaces and completed as a 3D object. But it is never easy to define an imaginary form clearly into a 3D digital model. So it tends to be an inaccurate object difficult to construct each component surface, or even to be a different shape from what it was planned at first. It is caused by the fact that the analytic modeling ability is not obtained just by learning computer techniques or by applying prototyping machines. Consequently, this study is focused on providing guidelines for the students who are learning car design, to analyze shapes in more systematic way, through the ideation process by isometric sketches based on the digital process of italian 'Carrozzeia'.
