When measuring cerebrovascular with 3D rotational angiography, the accuracy was verified by comparing the actual size and measurement size, respectively. It is intended to help select therapeutic materials and instruments during cerebrovascular intervention by comparing the average error rates for measured values in the 3DRA and CTA methods by examining with protocols such as brain CTA, which are always performed in emergency situations. The mean error rate between the groups of measurers was ±3.655% for radiation technologist and ±3.331% for university students, and the mean error rate of the student group was within tolerance (±10%), and the independent sample T-test result t =0.879, p=0.394 (p>0.05) showed no statistically difference between the two. In addition, the average error rate measured by both groups by 3DRA was measured below ±5% within the tolerance error rate (±10%), and most of CTA was measured within the tolerance range (±10%), but showed an average error rate of up to 5.65%, and the independent sample T-test result was statistically more accurate than 3DRA. Both the 3DRA method and the brain CTA method for measuring cerebrovascular size could be accurately measured within tolerance, but it would be better to measure cerebrovascular blood vessels using a more accurate 3DRA method during cerebrovascular intervention.

National competency standards, which are the contents of the knowledge, skills and attitudes required to perform a job in industry, is organized by the country. the job performance was evaluated based on the National competency standards from the third-year grade of radiology students by using field-based training courses. according to the evaluation results, students showed over 93% satisfactory ratio of job performance in all radiography projection methods. Therefore, it can be predicted that field-based training courses for students made a positive effect on improving their job performance. Exposure methods with CR equipment were evaluated the best rating, yet it has various problems. The standard deviation between students was very high, and the CR operation skill of students was insufficient. Film methods was evaluated also showed problems, due to the exposure condition setting and developing operation. although DR method was rated good to the students, it was evaluated that the operation skill of DR and the ancillary equipment operation skill was shortage. By supplementing the evaluation factors below proficiency levels to a course management in each exposure method, it could help students course achievement. Also, it could help students to improve job performance of clinical areas after graduation.

This study is to investigate the satisfaction rate and relative factors from the students majored in Radiology, Clinical Pathology and Physical Therapy, which can provide basic knowledge of satisfaction and guide the university life and further careers. The survey was performed with respect to 107 students of Radiology, 97 of Clinical Pathology and 89 of Physical Therapy at three-year or four-year colleges(universities) located in Busan and Gyeongsangnam-do. The results show that the satisfaction rate through whole majors was $3.40{\pm}0.57$ point. The scores of each major are: $3.38{\pm}0.62$ for Radiology, $3.37{\pm}0.56$ for Clinical Pathology, and $3.45{\pm}0.50$ for Physical Therapy. The score of social status was highest and the environment of major was the lowest. The satisfaction of three-year colleges was higher than that of four-year universities. Academic system, social status and adaptation to major affected satisfaction on major. In addition job outlook affected on all majors. Thus, we propose that every major must be equipped with specialized environment different from general colleges (universities), and provide environment where students can cause self-motivation. In addition, we found the special way to improve social status and satisfaction by using career guidance, offering career information and performing university-industry collaborations. Especially, it is important to improve the satisfaction on major of students at four-year universities.

This study was based on the data of total mineral content of about 99% at the age of 16-26 years, we aimed at female university students who are important for bone formation in their early 20s. The purpose of this study was to investigate factors of eating habits affecting their bone density and to provide data to prevent osteoporosis which might occur in the future. It was conducted on 100 female university students in their 20s, the bone mineral density according to BMI was measured by DEAX, and the analysis of 10 eating habits items and the results of BMD measurement on their own results in Excel 2010. As a result, the height was $161.08{\pm}4.70cm$, the weight was $52.43{\pm}6.43kg$, and the BMI was $20.22{\pm}2.48$, which correlated with BMD (p<0.05). According to the BMI classification, 20 had low weight and 80 had normal weight, and BMD was $0.20{\pm}0.41$ at normal weight. In the same sex, the mean T-score of the young adult group was $-0.04{\pm}0.99$ compared with the BMD of the young adult group, and the mean Z-score of the same age group was $0.02{\pm}0.93$ (p<0.001). Eating habits affecting bone mineral density were significantly affected by 3 meals per day, 1-3 cups of coffee per day and p<0.05 for Low salt formula intake. 6-9 dairy product intake was also p<0.05 but not significant. Therefore, it is considered that when 20s female students become middle-aged woman, they should have proper eating habits so that osteogenesis can be improved at young age in order to prevent bone disease.

In this study, we are purposed to find the educational effect of practical training using a 3D printed structure-based blind box on multidimensional radiographic image interpretation. The subjects were 83 (male: 49, female: 34) 2nd year radiological science students who participated in the digital medical imaging practice that was conducted for 3 years from 2020 to 2022. The learning method used 3D printing technology to print out the inside structure of the blind box designed by itself. After taking X-rays 3 times (x, y, z axis), the structure images in the blind box were analyzed for each small group. We made the 3D structure that was self-made with clay based on our 2D radiographic images. After taking X-rays of the 3D structure, it was compared whether it matches the structural image of the blind box. The educational effect for the practical training surveyed class faithfulness, radiographic image interpretation ability (attenuation concept, contrast concept, windowing concept, 3-dimensional reading ability), class satisfaction (interest, external recommendation, immersion) on a 5-point Likert scale as an anonymous student self-writing method. As a result, all evaluation items had high positive effects without significant differences between males and females. Practical education using blind boxes is a meaningful example of radiology education technology using 3D printing technology, and it is expected to be used as content to improve students' problem-solving skills and increase satisfaction with major subjects.

This study explored several agenda related to license system, education, professional work of radiological technologists(RTs) and a transition process of law for them to investigate a developmental strategy of RTs as a professional career. The results are as followings : 1. The national license system for RTs was started from 1965, 1965-1972 x-ray technicians(medical assistance), 1973-present(2006) radiotechnologist(medical technologist) since then. 2. The average pass ratio of national license examination(1965-2006) for RTs was 46.6%. The method, subjects and level of the examination should be improved. 3. The education term for RTs has been changed since 1963 ; 1963-1990 two year college, 1991-1999 three year college, 2000-2006 four year and three year college depending on universities and colleges. As of 2006, there are twelve 4-year universities and eighteen 3-year colleges. The total number of new students were 1,956. 4. The new developmental paradigm should be made for technology education of RTs corresponding to the development of medicine and science. 5. The qualification system of clinical specialists in radio-technology field needs to be operated not by the non-governmental body(The Korean Radiological Technologists Association) but by the governmental body. 6. The vertical relationship among RTs, doctors and other medical workers should be rebuilt through the revision of law. Especially, doctors and dentists 'guidance authority' for RTs should be changed to 'request authority'. 7. The service extent of RTs should be extended in medical fields corresponding to professional work of RTs and a revision of the law needed for this situation.

The purpose of this study was to investigate the knowledge and awareness about radiation use among non - radiation undergraduates. This analysis were used based on the collected questionnaires with Frequency, mean and standard deviation, t-test, one-way ANOVA. As a result, there was no significant difference between the groups in terms of gender and age. There were statistical differences in some items in the major field. In addition, the perception of radiation was more negative in women and under 25 years of age (p<0.05). The correlations between the sub - factors showed that the higher the knowledge of radiation, the higher the perception of knowledge and use of radiation. It is believed that university students will have a positive effect of contributing to the development of the radiation industry if they have a correct understanding of radiation because they are more likely to contribute to public opinion by advancing into society.
