최근의 의료방사선과학기술은 관련 환경의 발달로 의료산업과 융합하여 하루가 다르게 발전하고 있다. 이에 따라 학부와 대학원에서 방사선학교육과정이 개설됨에 따라 다른 학문 영역의 빠른 변화에 부응하여 다양한 프로그램으로 운영되고 있다. 그러나 국내 방사선학전공 분야의 대학원은 개설이 일천하여 교육 체계는 이에 부응하지 못하고 있는 실정이다. 현재 방사선과학의 교육과정은 기술과 학문으로서 인격 및 지식교육 그리고 보건의료전문인력으로서 기술 직업교육의 양대 큰 줄기를 병행하여 발전해야 한다는 명제로 볼 때 현 교육 환경과 임상이나 관련 산업에 적응하기에는 다소 무리가 있다. 특히 의료 환경의 변화와 이에 따른 교육과 연구가 다양화, 전문화, 세분화되고 있는 상황에서 방사선학 전공분야의 대학원 교육과정 개선과 바람직한 방향제시가 절실히 필요하다. 이러한 과정을 통하여 시대적, 사회적 요구에 부합하고 자질과 위상을 높일 수 있는 계기가 될 것으로 기대된다. 따라서 본 논문에서는 미국에서 현재 운영되고 있는 석사 및 박사과정의 대학원 교육과정을 분석하며, 현재 국내에서 개설 운용하고 있는 방사선학과 대학원 교육과정의 현황을 고찰하였고, 이를 기초자료로 하여 새로운 교육과정을 도입하기 위한 개선 방향을 제안하였다.

In this study, an electron-scattering device was fabricated to practically use the ultra-high dose rate electron beams for the FLASH preclinical research in Dongnam Institute of Radiological and Medical Sciences. The Dongnam Institute of Radiological and Medical Sciences has been involved in the investigation of linear accelerators for preclinical research and has recently implemented FLASH electron beams. To determine the geometry of the scattering device for the FLASH preclinical research with a 6-MeV linear accelerator, the Monte Carlo N-particle transport code was exploited. By employing the fabricated scattering device, the off-axis and depth dose distributions were measured with radiochromic films. The generated mean energy of electron beams via the scattering device was 4.3 MeV, and the symmetry and flatness of the off-axis dose distribution were 0.11% and 2.33%, respectively. Finally, the doses per pulse were obtained as a function of the source to surface distance (SSD); the measured dose per pulse varied from 4.0 to 0.2 Gy/pulse at an SSD range of 20-90 cm. At an SSD of 30 cm with a 100-Hz repetition rate, the dose rate was 180 Gy/s, which is sufficient for the preclinical FLASH studies.

In order to provide high-quality medical services to the public and contribute to the improvement of public health, it is necessary to enact an independent law according to the work of radiological technologists. Therefore, this study intends to review the regulations related to radiographers in the Medical Service Technologists, etc. Act. and to present opinions and directions for enactment of individual laws for radiological technologists. An online survey was conducted to 15,000 radiological technologists working in medical institutions and education sites in Korea; 1,027 people (6.85%) responded. The questionnaire consisted of 3 questions on demographic characteristics, 5 questions on the scope of work, and 12 questions on the revision of the Medical Service Technologists, etc. Act. and the establishment of the Radiological Technologist Independent Act. Reliability and factor analysis were performed on 9 questions measured on a Likert 5-point scale in "Revision of the Medical Service Technologists, etc. Act. and the establishment of the Radiological echnologist Independent Act" among the questionnaire items. Reliability for the total 9 questions was Chronbach α=0.728. There was a high perception that the regulations related to radiological technologists were insufficient in the current Medical Service Technologists, etc. Act., and the perception that examinations performed by radiological technologists at medical institutions were included in medical practice was high. If the Radiological Technologist Independent Act is enforced, a high percentage of respondents said that they could receive legal protection through the institutionalization of the scope of work, that the status of radiological technologists would be improved, and the scope of work would be expanded. The response that the scope of work of radiological technologists should be included was the highest at 96.6%. In the analysis according to demographic characteristics, it was found that 96.7% of the respondents were agreed regardless of the factors. Radiological technologists will have to work hard to secure the public health by coping with new radiology devices, procedures and treatment methods. Therefore, as the results of this study, it is expected that the enactment and implementation of the Radiological Technologist Independent Act will contribute to the improvement of the quality of treatment for patients and to the public health.

This study discussed the validity and necessity of compulsory recording of radiographic examination performed by radiological technologist on patients in medical institutions related to radiation exposure. Also, this study provided reasonable evidence of radiographic examination related medical records can contribute to the improvement of public health. Based on overseas cases of implementing a radiographic examination record system, the essential items to be included in medical record are the exposure date, exposure time, exposure method, exposure conditions that is tube voltage, tube current. Name and license number of the radiological technologist who performed the examination should be include in medical record. It is expected that the medical record of the total amount of radiation exposure per year would be in giving the maximum benefit with the minimum exposure to the medical radiation examination of the patient. In addition, interventional radiography medical record should also include exposure time, type and dose of the contrast medium.

This study was conducted to analyze factors Influencing Protective Behavior against Radiation Exposure using questionnaires for 231 radiological technologists working in Computed Tomography(CT) examination room with high radiation dose in diagnostic radiology field. Statistical analysis of the collected data revealed that the reasons for partially shielding the examination part in the CT scan were the lack of protective equipment, securing of radiation justification, being annoying and maybe not being harm to adults in order. It was also revealed that the variables influencing the protective behavior were protective behavior against radiation harm, self-efficacy, protective environment, organization culture, protective knowledge and protective instrument in order. The higher the radiological protective environment(${\beta}=0.245$) and the lower the radiological protective knowledge(${\beta}=-0.034$), the more influential the protective behavior against radiation harm was. In this study, it was shown that non examination parts were not shielded in the CT scan. Therefore, it is necessary to improve the level of protective environment, to cultivate knowledge to improve the protective behavior against radiation harm and to have an intervention strategy for concrete action.

The purpose of this study is to check the extent to which "instruction of physician or dentist" defined in the Medical Service Technologists, etc. Act is applied in relation to radiography examination procedures for radiological technologists. In addition, it is intended to present basic data on the requirement to revise the Medical Service Technologists, etc. Act in the radiological technologist's duty area and scope of work, The subjects of this study were radiological technologists with license, and the response data were collected after sending the questionnaire link written on the online questionnaire form. The final number of respondents were 1,018, and the response rate was 6.8%. Most of the negative responses were "I have never received 'instruction' for radiologic examination by a physician or dentist, including a radiologist in a medical environment." There were a high perception that "the professionalism in radiation examination on radiological technologists are higher than that of a physician or dentist." They answered that the current continuing education has a great impact on maintaining and continuing professionalism and learning new knowledge in the radiology field. In addition, the radiological technologists provide a very high level of education in areas related to radiography procedure ethics such as patient care, patient safety, and patient privacy protection, as well as specialized fields such as radiation-related examination methods, radiography examination dose, and patient exposure dose. Radiological technologists replied that they were receiving it consistently. In conclusion, in the current medical environment, the 'instruction' of a physician or dentist cannot be seen as being realistically performed. The phrase 'instruction' of a physician or dentist as defined in the Medical Service Technologists, etc. Act is considered inappropriate in respect of the fact that the state recognizes the qualifications of the medical service technologist through a license. It is thought that revision to a new term suitable for the current medical environment is necessary.
