With the increasing role of environmental design in promoting urban safety, new design attempts have been made to improve pedestrian safety in crosswalks. This study proposes an evidence-based design solution for improving crosswalk function by conducting simulations and field experiments. Drivers with more than one-year driving experience participated in this study. Four different crosswalk design patterns were prepared: (1) a zebra pattern, (2) zebra pattern with colored triangles, (3) 3D pattern, and (4) art pattern with unique colors and design. The results supported that the zebra pattern with colored triangles could be the most effective solution for crosswalk design by increasing visibility, attention, deceleration, and landscape aesthetics. This study provided objective data to support the performance of various crosswalk patterns and suggested the need to reevaluate the present crosswalk design guidelines.

Purpose In this study, radiation workers who work in nuclear medicine department were analyzed to find the cause of differences of radiation exposure from General Characteristic, Knowledge, Recognition and Conduct, especially females working on nuclear medicine radiation, in order to pave the way for positive defense against radiation exposure. Materials and Methods The subjects were 106 radiation workers who were divided into two groups of sixty-four males and forty-two females answered questions about their General Characteristic, Knowledge, Recognition, Conduct, and radiation exposure dose which was measured by TLD (Thermo Luminescence Dosimeter). Results The results of the analysis revealed that as the higher score of knowledge and conduct was shown, the radiation exposure decreased in female groups, and as the higher score of conduct was shown, the radiation exposure decreased in male groups. In the correlation analysis of female groups, the non-experienced in pregnancy showed decreasing amount of radiation exposure as the score of knowledge and conduct was higher and the experienced in pregnancy showed decreasing amount of radiation exposure as the score of recognition and conduct was higher. In the regression analysis on related factors of radiation exposure dose of nuclear medicine radiation workers, the gender caused the meaningful result and the amount of radiation exposure of female groups compared to male groups. In the regression analysis on related factors of radiation exposure dose of female groups, the factor of conduct showed a meaningful result and the amount of radiation exposure of the experienced in pregnancy was lower compared to the non-experienced. Conclusion The conclusion of this study revealed that radiation exposure of female groups was lower than that of male groups. Therefore, male groups need to more actively defend themselves against radiation exposure. Among the female groups, the experienced in pregnancy who have an active defense tendency showed a lower radiation exposure. Thus, those who have never been pregnant need to have a more active defensive conduct for the future possibility of pregnancy.

Astonish TF 재구성 기법의 적용을 통한 체적 크기의 변화에 따른 표준섭취계수(SUV)에 관한 고찰

이주영,남궁식,김지현,박훈희,Lee, Juyoung,Nam-Kung, Sik,Kim, Ji-Hyeon,Park, Hoon-Hee 대한핵의학기술학회 2014 핵의학 기술 Vol.18 No.1

PET 영상의 질 향상과 더불어 많은 연구를 통해 다양한 프로그램의 개발이 이루어지고 있다. 그 중 Philips 사의 Astonish TF 재구성 기법은 기존보다 빠른 재구성 속도와 함께 2 mm의 영상 재구성이 가능하여 병변의 향상된 대조도를 확인할 수 있다. 본 연구에서는 전신 $^{18}F-FDG$ PET 영상에서 기존의 4 mm와 2 mm 재구성 기법에 따른 표준섭취계수(SUV)를 비교 평가하였다. GEMINI TF 64 PET/CT (Philips, Cleveland, USA)를 사용하여 팬텀실험은 NEMA IEC Body Phantom (sphere: 10, 13, 17, 22, 28, 37 mm)으로 영상을 획득하였고, 임상영상은 유방암 진단을 받은 여자 30명(연령: $55.1{\pm}11.3$세, BMI: $24.1{\pm}2.9$)을 대상으로 $^{18}F-FDG$ PET/CT 검사를 시행한 후, 각각 4 mm와 2 mm로 영상을 재구성하였다. 획득된 영상은 EBW (Extended Brilliance Workstation) NM ver.1.0을 통해 팬텀과 임상영상에 관심영역을 설정하고, 표준섭취계수를 측정하였으며, SPSS ver.17.로 통계 분석하였다. 팬텀실험에서 90 sec로 획득한 영상의 4 mm와 2 mm 재구성 영상의 $SUV_{Max}$를 비교한 결과, 열소의 크기가 작을수록 $SUV_{Max}$의 편차가 크게 나타났고, 150 sec로 획득한 영상의 4 mm와 2 mm 재구성 영상의 $SUV_{Max}$를 비교한 결과에서도 같은 성향을 나타냈다. 90 sec와 150 sec로 획득한 영상의 $SUV_{Max}$의 편차 정도는 90 sec로 영상을 획득하였을 경우 보다 150 sec로 획득한 영상에서 열소의 크기가 작을수록 큰 차이를 나타냈고, 열소의 크기가 클수록 작은 차이를 나타냈다. 임상영상에서는 4 mm와 2 mm 재구성 기법을 분석한 결과, 표준섭취계수는 4 mm보다 2 mm 재구성 기법에서 높게 나타났고, 또한 체적이 작을수록 변화율이 증가하였다. Astonish TF 재구성 기법을 적용한 팬텀실험과 임상영상의 분석 결과, 체적의 크기가 작을수록 표준섭취계수의 변화율이 증가하였다. 그러므로 임상에서 대조도 및 병변 감별력이 우수한 2 mm 재구성 기법의 정확하고 적극적인 활용을 위하여 표준섭취계수 보정에 대한 추가적인 연구가 필요할 것으로 사료된다. Purpose: In addition to improving the quality of the PET image, through much research, the development of various programs are performed. Astonish TF reconstruction techniques by Philips can confirm the improved contrast of the lesion. Also, It's image reconstruction of 2 mm is possible with rapid reconstruction rate than conventional. In this study, we compared and evaluated Standardized Uptake Value (SUV) in accordance with the 2 mm reconstruction techniques and traditional 4 mm from the $^{18}F-FDG$ PET whole body image. Materials and Methods: In the phantom experiment, NEMA IEC body phantom (sphere: 10, 13, 17, 22, 28, 37 mm) was used to obtain images by using GEMINI TF 64 PET/CT (Philips, Cleveland, USA). Also, In the clinical images, we performed $^{18}F-FDG$ PET/CT examination to 30 women (age: $55.1{\pm}11.3$, BMI: $24.1{\pm}2.9$) with a diagnosis of breast cancer. After that, we reconstructed images in 2 mm and 4 mm respectively. The region of interest was drawn to acquired images. Since then, we measured SUV and statistically analyzed with SPSS ver.18 by using EBW (Extended Brilliance Workstation) NM ver.1.0. Results: After analyzing the result of the phantom study, there was a tendency that the bigger hot sphere size, the higher SUV. If you compared the 2 mm reconstruction techniques to 4 mm, it increased 95.78% in 10 mm, 50.60% in 13 mm, 25.00% in 17 mm, 30.04% in 22 mm, 31.81% in 28 mm, and 27.84% in 37 mm. Through the result of the analysis of the 2 mm reconstruction techniques and 4 mm in clinical images, it appeared that SUV of 2 mm was higher than that of 4 mm. Also the smaller the volume was, the more the change rate increased. Conclusion: After analyzing the result of the clinical picture and phantom experiments applied by Astonish TF reconstruction techniques, as the size of the volume was small, the change rate of the SUV increased. Therefore, it was necessary to further research about the SUV correction for accurate and active utilization of 2 mm reconstruction techniques which had excellent lesion discrimination ability and contrast in clinic.

Prior researchers interpreted the records of criminal cases involving the Progressive Party from a historical perspective. In marked contrast to existing trends, this study examines the Progressive Party case records through the lens of archival science. This study dissects the Progressive Party case records as a single and complete record group and at each stage of their life cycle from police investigation through criminal prosecution to trial. This approach enables a holistic analysis of archival characteristics of the records. This study begins with an appraisal of the nature and types of case records generated and maintained by the various agencies in light of the investigatory authorities delegated to each institution. This study then dissects the police, prosecution, and Counter Intelligence Corps records leading up to the indictment of Progressive Party members as well as the court records of the trial that followed. In particular, this study reveals the insufficiency and illegality of the evidence against the defendants in the Progressive Party case from an archival standpoint. Setting aside the admissibility or strength of the evidence under criminal law, the present study demonstrates that the records lack reliability, authenticity, and integrity-the fundamental attributes required for evidentiary efficacy of records from an archival standpoint.

이주영(Lee, Juyoung),정광순(Jeong, Kwangsoon) 학습자중심교과교육학회 2021 학습자중심교과교육연구 Vol.21 No.14

목적 본 연구는 교사가 교육과정을 개발한 과정에서 Schwab의 실제기예(practical art)를 발휘하는 모습을 기술하고 탐색하였다. 방법 이를 위해서 L교사가 교실에서 한 수업 관련 자료를 수집하여, 교육과정 개발 사례로 기술하였다. 그리고 이 과정에서 교사가 발휘한 실제기예를 분석하였다. 결과 첫째, 교사는 자신의 수업을 개선하는 과정이 곧 교육과정을 개발하는 과정임을 알 수 있었다. 둘째, 교사는 교육과정을 개발하는 과정에서 문제 인식 기예‣문제 구체화 기예‣문제 해결 기예를 발휘하는 것을 탐색할 수 있었다. 결론 본 연구 결과를 통하여 세 가지 결론을 내릴 수 있었다. 첫째, 교사가 개발한 교육과정 자체가 Schwab이 말하는 the practical이라는 점, 둘째, 교사는 실제기예를 발휘하면서 교육과정을 개발한다는 점, 셋째, 이런 실제기예를 발휘할수록 교사가 개발하는 교육과정(실제)는 통합수업으로, 즉 학생에게로 다가간다는 것을 알 수 있었다. Objectives The purposes of this study was to describe the curriculum developed by teachers who use the practical art as Schwab calls it, and to demonstrate the practical art, one of the skills teachers demonstrate in the process of developing the curriculum. Methods To this, first, we described as the teacher’s curriculum development. Second, based on this explanation, we analyzed the practical art that the teacher performed. In this respect, the study is one of the case studies. Results As a result of this study, first, teachers could see that the process of improving their classes was the process of developing a curriculum. Second, the practical art displayed by this teacher in each class were shown in the process of problem recognizing art ‣ problem refining art ‣ problem solving art. Conclusions Three conclusions were drawn through this study. First, the curriculum developed by the teacher itself is what Schwab calls the practical. Second, teacher develop curriculum using the practical art. Third, the more practical teachers use the practical art, the closer they become to students. In other words, it is closer to curriculum integration.
