The study analyzes the relationship between demand, satisfaction, and perception for non-face-to-face continuing medical education(CME) conducted in 2020 for 225 radiological technologist license holders working in the Busan area, and the factors that influence the positive perception of CME. T-test and one way ANOVA were used, and stepwise multiple regression analysis was performed. As a result, there were high demands for mobile publicity, professional radiological technologist, educational expenses support from institution heads, and CME. Male radiological technologist, over 50 years of age, and the more experienced they had a job chance, the more they had a positive perception. In the correlation between variables, the perception of the education system and the need for education showed a positive correlation. The higher the satisfaction with the education system, the higher the perception of the need for education. About 53% of the content was satisfied. Therefore, in order to raise awareness of CME, it is considered that policy changes to the education system are necessary first of all. It is considered that the search for the development of education content and educational content is necessary above all.

In order to assess policies for training of radiological technologists and public health, this study was conducted from the mid July to the end of August 2003 to the subjects of 890 radiological technologists who work at 44 general hospitals in 16 cities and provinces of the country. For this purpose, an analysis of variance was performed by regions divided in Capital city, metropolitan areas and small- and medium-sized cities as well as by length of service. The outcomes look as follows : 1. From the analysis of replies to questions about the government health policy for radiological technologists, high scores were given to the items: "the Law of Medical Engineers should be revised from the pattern of supervision to assignment" and "the medical institutions should be legally obliged to secure certain number of radiological technologists". 2. From the analysis of variance by regions and groups, there was difference by regions in the items: "demand and supply of radiological technologists should be controlled" and "the license number of radiological technologists should be indicated in the medical insurance bill"(p<0.000). 3. From the analysis of variance as to training of radiological technologists, a significant difference was found by length of service in the items: "it is necessary to open a 4-year department of radiology and to revise curriculum" and "the legal system to indicate license number of radiological technologists in the medical insurance bill should be introduced". 4. The analysis of variance by length of service revealed that those who have served for more than 20 years favored "it is necessary to open a 4-year department of radiology and to revise curriculum" higher than those who have served for less than 5 years, showing a tendency the longer they work, the stronger they feel necessity".

It is necessary to obtain images of high diagnosis worth based on ability and skill of radiological technologist in case of acquisition of medical radiologaphy information. In addition, we need the various kinds of education considering individual radiological technologist variation and the organization of clinical education according to the large amount of learning and more expensive knowledge of radiology. In this paper, we implement CAI system for cervical vertebrae fracture radiograph with multimedia authoring tools on web environments. The CAI system can train a new radiological technologist and study a lot of radiological technologist on the cervical vertebrae fracture radiography acquisition based on more objective and systematical data in radiography room. The proposed CAI system is also expected as a useful program which can help to cure patients based on accurate diagnosis as well as obtain radiography more quickly using a technology of radiography acquisition for cervical vertebrae fracture.

146 people working in the ultrasound room in Busan were surveyed, and their perception of hospital infection was analyzed. According to the results of the survey, academic background showed the highest number in terms of awareness and performance of personal hygiene management and hand washing management, and the group with experience of infection education showed the highest number in terms of awareness of ultrasound equipment hygiene, and the group with less than college education showed the highest number in terms of performance of ultrasound equipment hygiene. The difference was statistically significant. Based on the results of this study, performance was lower than awareness in general. This result indicates that the degree of performance is inadequate. Therefore, it can be concluded that individuals need to change their perception of personal hygiene and take interest in it through infection education.
