In this study, the purpose of this study was to analyze the degree of exposure of radiation workers assigned to the Department of Radiology and frequent visitors during on-campus practice, and to conduct a basic study on the feasibility and optimization of the radiation protection of the Nuclear Safety Act for the Department of Radiology. . The average exposure dose of occupational workers by year was 0.01 mSv, the lowest in 2014 and 2016. The highest figure was 0.12 mSv in 2018. The average exposure dose of frequent visitors by year was the lowest at 0.013 mSv in 2018, and the highest at 0.022 mSv in 2016. According to this study, the annual exposure dose received by professors, practical assistants, and students in the department of radiology (department) who use only radiation generators in the course of in-school practice is less than 1 mSv, which is the dose limit for the general public. Therefore, at the time when the radiation dose of students in the Department of Radiology is lower than the dose limit of the general public, the current safety regulation of the Nuclear Safety law is judged to be excessive regulation. Therefore, it is considered necessary to revise the regulations for radiation generators in the current Nuclear Safety law or to revise the radiation safety management system for university students.

This study attempts to provide basic information on overseas employment to the radiological technologists and students majoring in radiology in Korea who consider the overseas employment by investigating the job consciousness for radiological technologists in Canada and Australia which have a high level of interest for overseas employment and want to compare their status with that of Korean radiological technologists. This study was performed by visiting hospitals such as Prince George Regional Hospital, 1475 Edmonton Street, Prince George, BC, Canada on August 13, 2007, Alfred Hospital, Commercial Road Melbourne 3004, Australia on August 4, 2008, and other Korea hospitals that show the similar scale as Canada and Australia on September 10, 2007. The results were summarized as follows : 1. Differences were observed in this sexual composition, such as 18 males (90%) in Korea, 14 females (73.7%) in Canada, and 25 females in Australia (86.2%). 2. The item of 'aptitude' which is one of the most important criteria, showed the highest level in Korea, Canada, and Australia, and the second most considered item was 'salary'. 3. In the values in jobs, the items of 'economic self-sufficiency', 'recognized by others', and 'establishing a social position' represented high levels in Korea, and the items of 'like the job itself', 'establishing self-actualization', 'feel the meaning of life', and 'make new friends' showed high levels in Canada and Australia. 4. Regarding the item of 'a job is important as much as a marriage', 'Yes' showed high level in Korea, and 'No' showed high levels in Canada and Australia. 5. Radiological technologists in Korea demonstrated a low level in the job consciousness compared to those of Canada and Australia. Although this study shows some limitations for showing whole idea of radiological technologists due to the lack of the scope in samples for each country as a practical manner, this study can be regarded significant to compare some countries that have interests in overseas employment.

The bone mineral density built in adolescence and college term is formed to the highest level between 25 years old and 35 years old and the formed bone mineral density is decreasing in the middle years and senescence. Decrease of the bone mineral density causes Osteopenia and an increase of dangerousness of a bone fracture which become social health problems. This research is to give guidance for the right living style by surveying the relation between the bone mineral density and college students' life. The result is like below. First of all, most objects of the research were insufficient of quantity of motion and the diet they have was consisted of instant food. It was far from the right living habit and exercise and the bone mineral density was also low. Second of all, male students showed more osteopenia than female students in this research and the smokers' bone mineral density was lower than nonsmokers, which proved that smoking in adolescence was related to the bone mineral density. Finally, the opportunistic eating and living style and the excessive diet and unequal caloric intake caused by the notion of preference for a slim person are considered to be the main reasons for the decrease of the bone mineral density.

The clinical practices provide the students with a good opportunity to study the practical experiences in their field through the clinical training education in hospital. Now, in this study, comparing the perceptions of the clinic teachers with those of students at the clinical site. The study was conducted to the students attending universities located in Seoul and who finished the clinical practices in 2013. The questionnaires were distributed to the student and collected from them. The study were conducted to 275 questionnaires with frequency analysis, crosstabs, chi-square test and McNemar test. The major motivation was of the select radiography course was high employment rate(44.0%) and the satisfaction of radiography course was general(53.1%). 51.3% of the study answered 8 weeks current duration of clinical practices is proper. The 3-year course students answered that the period of clinical practices would be proper if it is performed in the winter vacation in their second year in college(47.3%). The 4-year course students answered that the first semester in their third years is proper for clinical practices( 27.7%). The students answered that they felt the lack in their knowledge on the professional field(32.4%) during the clinical practices and some of the practical training is different from the education performed at school(68.4%). Most of answered that they were satisfied with the clinical practices and among them they recognized the importance of the clinical practices ($3.94{\pm}0.89$). After the clinical practices, their desire for getting job as a radiography has changed from 84.1% to 82.9%. The reason why they want the job related to the radiation is because the job is stable (changed from 49.0% to 46.0% after the clinical practice) while the reason why they don't want be a radigrapher because that job is not proper for them (changed from 37.0% to 40.7% after the clinical practice) The effort should be made to enhance the position of radiation professionals through the improved education system to the students, rather giving them education for just employment.

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.
