A Comparative Study between Evaluation Methods for Quality Control Procedures for Determining the Accuracy of PET/CT Registration

차민경,고현수,정우영,류재광,최보영 한국물리학회 2015 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.67 No.3

The Accuracy of registration between positron emission tomography (PET) and computed tomography (CT) images is one of the important factors for reliable diagnosis in PET/CT examinations. Although quality control (QC) for checking alignment of PET and CT images should be performed periodically, the procedures have not been fully established. The aim of this study is to determine optimal quality control (QC) procedures that can be performed at the user level to ensure the accuracy of PET/CT registration. Two phantoms were used to carry out this study: the American college of Radiology (ACR)-approved PET phantom and National Electrical Manufacturers Association (NEMA) International Electrotechnical Commission (IEC) body phantom, containing fillable spheres. All PET/CT images were acquired on a Biograph TruePoint 40 PET/CT scanner using routine protocols. To measure registration error, the spatial coordinates of the estimated centers of the target slice (spheres) was calculated independently for the PET and the CT images in two ways. We compared the images from the ACR-approved PET phantom to that from the NEMA IEC body phantom. Also, we measured the total time required from phantom preparation to image analysis. The first analysis method showed a total difference of 0.636 ± 0.11 mm for the largest hot sphere and 0.198 ± 0.09 mm for the largest cold sphere in the case of the ACR-approved PET phantom. In the NEMA IEC body phantom, the total difference was 3.720 ± 0.97 mm for the largest hot sphere and 4.800 ± 0.85 mm for the largest cold sphere. The second analysis method showed that the differences in the x location at the line profile of the lesion on PET and CT were (1.33 , 1.33) mm for a bone lesion, (−1.26, −1.33) mm for an air lesion and (−1.67, −1.60) mm for a hot sphere lesion for the ACR-approved PET phantom. For the NEMA IEC body phantom, the differences in the x location at the line profile of the lesion on PET and CT were (−1.33, 4.00) mm for the air lesion and (1.33, −1.29) mm for a hot sphere lesion. These registration errors from this study were reasonable compared to the errors reported in previous studies. Meanwhile, the total time required from phantom preparation was 67.72 ± 4.50 min for the ACR-approved PET phantom and 96.78 ± 8.50 min for the NEMA IEC body phantom. When the registration errors and the lead times are considered, the method using the ACR-approved PET phantom was more practical and useful than the method using the NEMA IEC body phantom.

The standard and modified Proctor compaction tests have been widely used for evaluation of design properties and compaction characteristics of subgrade soils. However, different types of compaction roller equipment, each producing a different level of soil compaction, are used in the field for compaction of subgrade soils. The purpose of this research is to evaluate the compaction characteristics of domestic subgrade soil using the gyratory compactor made by Servopac to simulate field compaction conditions. Field compaction data and couple of properties were collected from road construction site. Disturbed soils was used for laboratory compaction and gyratory compaction. For the comparison, block sampling was conducted on the subgrade after finishing the final compaction.

온라인 미디어 시대의 관객개발을 위한 문화자본, 정보자본, 사회자본의 활용 전략 연구 - 앙상블 디토 관객 분석을 중심으로 -

본 연구는 클래식 음악 공연 선택에 있어 문화자본의 중요성에 대해 고찰하고, 문화자본 증진을 위한 정보자본과 사회자본의 역할을 분석함으로써 이를 활용한 공연예술 관객개발전략을 위한 시사점을 제공하고자 한다. 이를 위해 ‘앙상블 디토’ 공연의 관객을 분석하여 이들의 공연관람에 영향을 미친 문화자본, 사회자본, 정보자본 간의 관계를 분석하였다. 연구결과, 앙상블 디토 관객은 80% 이상의 관객이 앙상블 디토를 브랜드 경험으로서 소비하였고 삶의 질을 높이는 하나의 수단으로서 클래식을 감상하였다. 이들은 클래식 음악에 대한 충분한 정보자본과 문화자본을 보유하지는 않지만, 온라인 미디어를 통한 사회자본을 통해 이들의 정보자본과 문화자본을 확대해 나가고 있었다. 앙상블 디토 공연만 관람하는 그룹들은 클래식음악에 대한 문화자본이 매우 낮으며 정보자본도 낮아 일회성 관객에 그치고 있었다. 앙상블 디토 관객의 연구 결과, 이들은 온라인 네트워크를 정보자본과 문화자본을 높이는 도구로서 활발히 이용하고 있었는데, 특히 온라인 네트워크의 확장된 사회자본은 이들의 정보자본 상승과 문화자본 축적에 매우 긍정적으로 기여하고 있었다.

수행되지 않은 과학하기와 전문가주의에 대한 도전: 1형 당뇨병 환우회의 사례

차민경,박희제 한국과학기술학회 2023 과학기술학연구 Vol.23 No.1

By attempting to answer to the questions “Why was the scientific knowledge needed by type 1 diabetes patients not produced?” and “How did the Korean Type 1 Diabetes Association get undone science done?”, this study examines the values of scientific knowledge production, in which citizens take the initiative, through the concept of Undone Science. Viewing the expert-centered health care system as an obstacle to the growth of scientific knowledge and technology for type 1 diabetes management, the Korean Type 1 Diabetes Association actively introduced and improved medical devices developed by oversea patient groups, and produced patient-led diabetes-related data. These activities of the Type 1 Diabetes Association have developed beyond scientific knowledge production into a social movement aimed at an alternative society of patient-centered care. Meanwhile, patient-led data produced by Type 1 Diabetes Association through civic hacking has become a key tool for them to negotiate and be recognized for their expertise in type 1 diabetes. The value of medical data measured through digital medical devices, which are rapidly emerging in medical science as guiding the future of medical science, also provided them with an opportunity structure to challenge to the expert-centered medical research systems. 이 연구는 “왜 1형 당뇨 환자들이 필요로 하는 지식은 만들어지지 않았는가?”, “1형 당뇨병 환우회는 어떻게 수행되지 않은 과학하기를 실행했는가?”라는 두 질문에 답함으로써, 시민들이 주도적으로 참여하는 과학지식 생산의 가치를 ‘수행되지 않은 과학(Undone Science)’이라는 개념을 통해 살펴본다. 한국 1형 당뇨병 환우회는 전문가 중심의 보건의료제도를 1형 당뇨 관리를 위한 지식과 기술의 성장을 방해하는 장애물로 보았고, 이를 극복하기 위해 적극적으로 해외 환자단체에 의해 개발된 의료기기를 도입하고 개선했으며, 환자주도로 당뇨 관련 데이터를 생산해나갔다. 이러한 1형 당뇨병 환우회의 활동은 단지 지식생산을 넘어 환자중심 의료라는 대안사회를 지향하는 사회운동으로 발전했다. 한편 한국 1형 당뇨병 환우회가 시빅 해킹을 통해 생산한 환자주도의 데이터는 이들이 1형 당뇨병에 대한 전문성을 협상하고 인정받게 하는 핵심적인 도구가 되었다. 의료과학에서 급부상하고 있는 디지털 의료기기를 통해 측정된 의료데이터의 가치가 이들에게 전문가 중심의 의료연구체제에 도전할 수 있는 기회구조를 제공한 것이다.

This study is to examine Ye(禮) contained in Li-Hexagram(履卦) and Hwa(和)'s plan in Zhouyi, focusing on the spirit of practice. It aims to contribute to leading a happy life by suggesting a way of harmony and harmony in an era of loss of humanity and social conflict and division through this. The word ‘Hwa(和)’ is mentioned total of 13 times in Zhouyi. Among them, the 7th chapter of Gyesahajeon(繫辭下傳) states, “The Li harmonizes and is filial[履和而至], and The Li harmonizes actions[履以和行]”, and is explained in relation to Li-Hexagram and Hwa. Based on this, the discussion was conducted focusing on the Li-Hexagram suggested as a way to realize ‘Hwa’ in this paper. As a result, Li(履) means courtesy and practice, and could be confirmed that the spirit of courtesy and its practice were emphasized through the Kwe-sa(卦辭) and Hyo-sa (爻辭), Dan-jeon(彖傳)」 and Sang-jeon(象傳)」 of Li-Hexagram. It is believed that it is possible to resolve the loss of humanity and social polarization that our society is currently experiencing, and complete one's character, realization of the public interest, and a politics of harmony according to Jung-do(中道) through the spirit of courtesy and practice contained in Li-Hexagram. We can establish a foundation for Virtue and Will rise up to the top state of Harmony, when we achieve Jung-jeol(中節) by practicing the etiquette spirit of courtesy such as ‘Distinction(分)’ and ‘Righteousness(義)’, ‘Respect and Caution(敬愼)’. This is the realization of Hwa through the practice of Courtesy.
