임상실습의 목표는 학생들이 유능한 방사선사가 되기 위해 필요한 기술(technic)과 태도(attitude) 그리고 지식을 학생들에게 가르치는 것이다. 이를 위해서는 의료기관이 갖추어야 할 교육시스템과 이를 운영할 임상교육 지도자가 확보되어야 한다. 임상기관에서 학생들을 가르치고 평가하기 위해서 반드시 높은 수준의 교육 시스템을 가져야 하는 것은 아니지만 적어도 임상지도자들이 학생들을 전문가로 육성하고 지도하는데 필요한 교육목표와 실습 수행 원칙은 가지고 있어야 한다. 임상실습을 담당하는 지도자는 적어도 유능한 임상실습 지도자의 자질과 구조적이며 능동적인 실습교육의 피드백 특성을 이해하고 수행할 수 있어야 한다. 그리고 평가와 피드백에 필요한 적절한 시간을 관리할 수 있어야 하며 실습 학생의 능력을 평가한 후 피드백을 제공할 수 있는 적절한 기술을 사용할 수 있어야 한다. 본 연구는 이러한 임상실습지도자의 특성을 제시하고 실제 임상현장에서 이루어지고 있는 우리나라의 방사선과 임상실습 현황의 한 예를 실습생 설문을 통하여 파악하고 문제점과 개선안을 찾아보고자 하였다.

The Nuclear Safety Commission amended the Nuclear Safety Act by strengthening the safety management system for the frequent workers to the level of radiation workers. And students entering radiation management zones for testing and practical purposes are subject to frequent workers. It is inevitable that this will incur additional costs. In this paper, the validity of the amendment to the Nuclear Safety Act was to be assessed in terms of radiation protection. Study subjects are from 2014 to 2016, among university students in Seong-nam Korea and comparisons for analyses were made taking into account variables that are differences in annual, practical types, on-class and clinical practice students exposure dose. The analysis showed that exposures between on-class and clinical practice received were less than the annual dose limit of 1 mSv for the public. Then, some alternatives that excluding from frequent workers during on-class practice or mitigating the frequent workers' safety regulation for only on-class frequent workers can be considered. Optimization is how rational is the reduction in exposure dose to the costs required. Therefore, the results are hardly considered for optimization. If the data accumulated, it could be considered that the revision of the act could be evaluated and improved.

The purpose of this study is to investigate various opinions on changes and revisions in the Medical Technician Act, to compare the curriculum of radiological technologist and physicians or dentists, and to compare the definitions and scope of work of radiological technologist in Korea and abroad. From the information, The goal is to review whether the phrase 'guidance of a doctor or dentist' specified in the definition of the 'Act on Medical Technicians, etc.' is realistically appropriate. radiological technologist receive specialized college education on radioligical science & medical imaging. The training hours for radiolgical science student are greater than medical students. In addition, radiological technologists are continuously developing their competencies for new knowledge and skills through continuing education in clinical fields. In particular, radiological technologist are making steady research efforts to reduce patient exposure and improve medical image quality. As a result of this investigation, it is considered that the term "guided by a doctor or dentist" as currently defined in the 'Act on Medical Technicians, etc.' may need to be revised in consideration of the professionalism of the radiological technologist.

New exercise technology such as the virtual reality (VR)-based exercise system is required to meet soaring demand for target participants in exercises and to alleviate the difficulties in personnel mobilization through an alternative approach to the exercise system. In a previous study, event tree methodologies were introduced in setting up an exercise scenario of a VR-based radiological exercise system. In the scenario, the locations at which major events occur are rephrased as nodes, routes as paths, and public response actions as protective actions or contents of an exercise at individual locations. In the study, a model for estimating effective doses to the participants is proposed to evaluate the exercise system, using the effective dose rates at particular times and locations derived from a computer program. The effective dose received by a student when she/he follows a successful route is about a half of the dose received when she/he does not follow the exercise guide directions. In addition, elapsed time to finish an exercise when following a successful route is less than one-third of the time spent to finish an exercise when following the guide's directions.

In this study, the applicability of machine learning for the development of a simulator for general X-ray examination education is evaluated. To this end, k-nearest neighbor(kNN), support vector machine(SVM) and neural network(NN) classification models are analyzed to present the most suitable model by analyzing the results. Image data was obtained by taking 100 photos each corresponding to Posterior anterior(PA), Posterior anterior oblique(Obl), Lateral(Lat), Fan lateral(Fan lat). 70% of the acquired 400 image data were used as training sets for learning machine learning models and 30% were used as test sets for evaluation. and prediction model was constructed for right-handed PA, Obl, Lat, Fan lat image classification. Based on the data set, after constructing the classification model using the kNN, SVM, and NN models, each model was compared through an error matrix. As a result of the evaluation, the accuracy of kNN was 0.967 area under curve(AUC) was 0.993, and the accuracy of SVM was 0.992 AUC was 1.000. The accuracy of NN was 0.992 and AUC was 0.999, which was slightly lower in kNN, but all three models recorded high accuracy and AUC. In this study, right-handed PA, Obl, Lat, Fan lat images were classified and predicted using the machine learning classification models, kNN, SVM, and NN models. The prediction showed that SVM and NN were the same at 0.992, and AUC was similar at 1.000 and 0.999, indicating that both models showed high predictive power and were applicable to educational simulators.

직업구조가 빠르게 변화하는 상황에서 기업들은 기초직업능력의 중요성을 더욱더 강조하고 있다. 이에 본 연구는 S대학교 재학생의 기초직업능력 수준을 파악하여, 기초자료를 제시하고자 하였다. 수집된 자료는 T-test 및 일원 분산분석(Oneway ANOVA)을 실시하였다. 연구결과 기초직업능력 일곱 개 영역에 있어 전반적으로 보통이상의 수준을 가지고 있는 것으로 조사되었다. 이 중 의사소통능력 중 읽기와 쓰기 능력이 가장 낮게 나타났으며, 그 다음이 조직이해능력 중 글로벌 문화를 이해하며 외국어를 활용할 수 있는 능력, 수리능력 순으로 나타났다. 반면에 대인관계능력이 가장 높은 수준으로 나타났다. 이는 앞으로 병원 근무에 있어서 환자 및 구성원들과 대인관계를 잘 형성할 수 있을 것으로 생각된다. 또한 의사소통능력 중 읽기와 쓰기 능력, 수리능력, 조직이해능력 중 글로벌 문화를 이해하며 외국어를 활용할 수 있는 능력이 학년 간에 통계적으로 유의한 차이가 있는 것으로 나타났다(P<0.01). 본 연구는 S대학교 방사선과 재학생을 대상으로 기초직업능력 수준을 파악하였기 때문에 연구결과를 전체 대학교 재학생 및 모든 학과에 대해 일반화하는데 다소 한계가 있을 수 있다. 이상의 결과를 토대로, 학생들이 의사소통능력, 수리능력, 조직이해능력, 자기관리능력 등을 향상시킬 수 있도록 전공 교육과정과 연계하여 지도하여야 할 것이다. 따라서, 우수한 직업기초능력을 갖춘 인재를 양성하기 위해 학과의 특성과 학생들의 특성을 잘 고려하여 학년별 및 학생 수준별로 진행될 수 있는 다양한 프로그램 활용 및 산업체와 잘 연계된 맞춤형 교육이 필요할 것으로 생각된다.
