Due to the development of advanced technology, a lot of digital radiographic equipment has been developed, which is very helpful for accurate diagnosis and treatment, and it is very important to train personnel who have acquired professional knowledge in order to use it safely and effectively. Students are exposed to the risk of radiation exposure in radiography training using diagnostic X-ray equipment, and some educational institutions do not use X-ray equipment due to management difficulties in accordance with the Nuclear Safety Act. As a solution to this, this study developed a medical radiation simulator for education that does not generate radiation by using a vision sensor and self-developed software. Through this, educational institutions can reduce the burden of administrative implementation according to the law, and students can obtain a high level of educational effects in a healthy practice environment without radiation exposure.

This study was carried out to investigate the combined effect of cold storage with irradiation on rooting of chrysanthemum cuttings. Each cutting was six cm in length with three real leaves. A set of Groups of the cuttings was irradiated with 0 to 70Gy of gamma-ray after four weeks of cold storage, while another groups were irradiated with the same doses and then stored at $4^\circ{C}$ for four weeks. Root and shoot growth were observed at 15 and 20 days after planting of the cuttings in a Plug tray. Accelerated root formation was observed in 30 Gy irradiated group, and root growth was also enhanced in 20 and 30 Gy irradiated groups 20 days after planting. In case of irradiation combined with pre-treatment of cold storage, survival rate of cuttings was the highest (80%) in 30 Gy irradiated group. The groups treated with irradiation first before cold storage were apparently better in root formation, among which 50 Gy irradiated group showed the highest rate of root growth.

현대인들은 다양한 전자기기 휴대폰, 컴퓨터, 전자레인지로부터 발생하는 전자파에 뇌를 노출시키고 있다. 전자기기의 전자파는 뇌에 중대한 손상을 가져올 수 있으며, 조기 노화를 초래할 수 있다고 경고하고 있다. 전자파의 실질적인 위험은 뇌가 열을 받는 것이 아니라 비열방사선이라고 널리는 강도가 낮은 방사선이라고 한다. 휴대폰, 컴퓨터의 모니터에서 발생되는 전자파에 장시간 노출로 인한 각종 전자파 유해가 생기고 여러 가지 신경 계통에 대한 장해가 증가하고 있다. 전자파가 인체에 미치는 영향에 대한 많은 연구가 이루어지고 있으나 서로 상반되는 연구결과가 많이 나타나고 있다.

In informational confusion of complicated society, self-esteem is considered as important psychological and temperamental factors for self-recognition and self-realization of youths. In this study, we found factors that affect self-esteem by investigating general characteristics and emotional intelligence of college student majoring in Radiological Science. The results showed that, in terms of general characteristics, age affects overall self-esteem, sex and school record affect a social self-esteem, and health affects self-esteem within the family as well as overall and social self-esteem.
