방사선 방호는 역동적이다. 위로는 방호의 개념과 틀에서부터 아래로는 사용하는 물리량과 수치 기준에 이르기까지 무엇 하나 불변인 것이 없어 보인다. 이와 같은 변화는 방사선의 작용과 생물보건학적 영향에 대한 우리 과학적 지식의 견고도도 관계되지만 방사선 방호가 본질적으로 과학의 문제만이 아니라 사회의 역동성과 연계되어 있기 때문이다. 방사선 위해도와 방호 체계에 상당한 변화가 있어 논

This paper investigates the influence of hydrogen loading process on the radiation sensitivity of fiber Bragg gratings (FBG). We made the FBG inscribed in the same commercial Ge-doped fiber with different hydrogen loading periods. We measured the Bragg wavelength shift (BWS) of the FBG exposed to gamma-radiation up to a dose of 18 kGy, and evaluated the change of full width at half maximum (FWHM) and the FBG temperature sensitivity coefficient after irradiation. Varying hydrogen loading parameter led to BWS differences up to nearly a factor of two.

This research, which was conducted for dental hygienists, intended to check out what factors have an influence on their practices by knowledge and attitude on radiation safety management (RSM). This study performed a survey on such an issue from July 2 to August 30, 2012 for 220 dental hygienists who worked in Busan, Gyeongnam areas. The data was analysed using the IBM SPSS Statistics 21.0 program. The results were as follows: As a result of the knowledge according to the general characteristics and RSM, a statistically meaningful difference was found according to the education on radiation and wearing apron. As for the attitude according to the general characteristics and RSM, a statistically meaningful difference was found according to the education on radiation and wearing apron. As to the practice according to the general characteristics and RSM, a statistically meaningful difference was found according to the education on radiation, wearing thermo luminescent dosimeter and wearing apron. When the analysis of safety management practice for radiation was conducted with the independent variables such as knowledge, altitude and health concerns about radiography, it turned out that the factors having an effect on the practice were altitude and health concerns by that order.

Effects of irradiation on physical and chemical properties of chicken were investigated. Chicken was irradiated at dose levels of 0, 0.5, 1, 3 and 5 kGy using Co60 source. Irradiation increased drip loss and TBA value. Irradiation decreased L value, and increased a value and b value, indicating that irradiation made chicken darker, more reddish and more yellowish. Irradiation induced the degradation in salt-soluble protein, not water-soluble protein. Any differences in color, odor and tenderness between irradiated and non-irradiated chicken were not perceived by sensory panels.

This study was conducted to understand the motivation for major selection and degree of satisfaction with major for university students in the department of Radiology, and to analyze the effect university life adjustment in COVID-19. From Jung 20 to July 20, 2021, 308 students in grades 1~4 were enrolled at universities in Busan and Gyeongnam. Factors influencing university life adjustment were found to have a good adjustment when majoring was selected with personal motive rather than social motive. Among the sub-factors of major satisfaction, general satisfaction and satisfaction with surrounding relationships had a positive effect on university life adjustment. Therefore, in order to adapt to healthy university life, it is necessary to secure closeness between school, professor, and students, and it is desirable to provide students with opportunities to experience various education by recognizing the rapidly changing policy changes in education to increase major satisfaction. Based on the results of this study, it is expected that the results of this study will be used as basic data for successful university life of students in the department of radiology.

This study intends to improve the radiation safety management and the recognition for handling radiation using structured questionnaires to dental hygienists working at Jeollabuk-do from September 1 to October 31 in 2014. As a result, 63% of respondents have not received education for radiation safety management. Moreover, the practical degree for radiation safety management was $2.58{\pm}1.11$, while the degree of knowledge was $3.74{\pm}0.83$ of total 5.0. The results of insecurity for radiation danger were high as $3.88{\pm}0.92$, and insecurity for fetus during pregnancy shows the highest value as $4.43{\pm}0.71$. From the results of statistical significance level, the knowledge degree of radiation safety management is affected by total numbers of radiograpy for a day (p<0.05), and the practical degree of radiation safety management is affected by age group, academic background, monthly income, continuous service year, practice area, present position, and status of radiography in present (p<0.05). In addition, the knowledge degree of radiation safety management have a negative correlation (r=-0.232) with the practical degree, but have a positive correlation (r=0.262) with the insecurity for radiation danger. The high knowledge degree of radiation safety management (${\beta}=0.252$, p<0.001) and the short radiography work period (${\beta}=-0.341$, p<0.05) were the influential factors to the insecurity for radiation danger. Consequently, countermeasures are necessary to encourage dental hygienists to put their radiation safety management knowledge into the practice and to reduce the insecurity degree for radiation danger. Furthermore, it is important to prevent psychological and physical risks by radiation exposure through the improvement of radiation safety management level and recognition for handling radiation to improve medical environment.
