A year has passed since the nuclear power plant accident in Fukushima on March 11, 2011, and a survey for public perception on radiation by Korean people has been made. The methodological design was based on a quantitative survey and a frequency analysis was done. The analysis objects were survey papers (n=2,754pcs) answered by random ordinary citizens chosen from all over the country. The questionnaires, and study tool, were directly distributed and collected. A total of 40 questionnaires using a coefficient of Cronbach's ${\alpha}$ per each area was 'self perception of radiation' (0.620), 'radiation risk' (0.830), 'benefit from radiation' (0.781), 'radiation controlled' (0.685), 'informative source of radiation' (0.831), 'influence degree from Fukushima accident' (0.763), showing rather high score from all areas. As the result of the questionnaires, the knowledge of radiation concept was 69.50 out of 100 points, which shows a rather significant difference from the result of 'know well about radiation' (53.7%) and 'just know about radiation' (37.40%). According to the survey, one of the main reasons why radiation seems risky was that once exposed to radiation, it may not have negative impacts presently but, the next generation could see negative impacts (66.1%). About 41% of our respondents showed a negative position against the government's report on radiation while 39.5% of respondents said that we should stop running nuclear power in light of Fukushima nuclear power plant accident. This study was done for the first time by Korean people's public perception on radiation after the Fukushima nuclear power plant accident. We expect this might have significant contributions to the establishment of the government's policy on radiation.

The goal of quality assurance (QA) is to minimize systematic errors in order to maintain the quality of a certain process. Statistical process control (SPC) has been utilized for QA in radiation therapy field since 2005 and is changing QA paradigm. Its purpose is to maintain a process within the given control limits while monitoring of error trends such as variation or dispersion. SPC can be applied to all QA aspects of radiotherapy; however, a medical physicist should have enough knowledge about the application of SPC to QC/QA procedures. In this paper, the author introduce a concept of SPC and review some previously reported studies those used SPC for QA in radiation therapy.

The purpose of this study is to analyze the social behavior, especially, the evacuation-related social behavior, of the transients in the radiological emergency planning zone(EPZ) of nuclear power plants. So, the meaning and kinds of the evacuation and the significance of the trip generation time(TGT) have been reviewed. The characteristics of the social behavior of the transient around Ulchin, Wolsong and Kori sites was analyzed through field surveys by using the questionnaire. The major findings of this research implications are as follows. First, for securing the safe evacuation, the alternatives to effectively provide the information on the evacuation warning may be prepared. Second, it is necessary to establish the education and training of transient's evacuation. Third, it is needed that the cause and background of the evacuation refusal are identified and the new response plan to secure transient's safety is prepared.

Based on the fact that studies on the use of radiations have not been largely conducted reflected on the importance of the use of radiations, the survey was performed to investigate the attitude on the use of radiations for some university students who have a high level of knowledges among average persons in order to extract certain directions for the education program to provide right information. The survey was performed for 517 university students from Oct. 10 to Oct. 15, 2005. The results of this survey can be summarized as follows. 1. Students who have experienced in the radiation related education presented statical differences in the results according to the majoring and monthly incomes. 2. Regarding the survey on the attitude of the use of radiations, the item of 'I agree to build a general hospital or university hospital where I lives in' was presented as the highest points of $3.73{\pm}1.004$, and the lowest point was recorded in the item of 'I agree to build an atomic wastes treatment facility where I live in' as the point of $2.63{\pm}1.091$. 3. The level of attitudes on 'I agree to build an atomic power plant or atomic wastes treatment facility where I live in' presented lower levels than that of the attitude on 'I agree to build an atomic power plant or atomic wastes treatment facility in my country'. 4. The lowest level recorded in the level of attitudes on 'I agree to build an atomic wastes treatment facility where I live in 'presented a significant difference according to the sex and grade.

Clinical experiment is a set of experience to help student acquire technic, attitude and knowledge by participating in the clinical work. The radiotechnologists who are employed in departments of radiology serve as clinical instructors. Their responsibilities include teaching students them to become competent radiotechnologist. Clinical instructors often have no formal preparation in teaching student. The purpose of this study is to review some principals that will help clinical instructors support and foster the professional development of student radiotechnologists. The clinical instructor should be able to identify the qualities of instructor, the characteristics of feedback and use facillitation skills when is evaluated student performance. And the survey was performed to evaluate the satisfaction of student participated in clinical experiment, the purpose of this research is to fine the problems and improvements in clinical experiment of student radiotechnologist in Korea.

단순 흉부 X-선 사진은 흉곽내에 공기를 함유하고 있는 폐실질, 심장과 대혈관을 포함한 연부조직, 그리고 흉곽을 이루는 골격 등의 다양한 조직으로 이루어진 3차원적인 해부학적 구조물을 X-선 film이라는 2차원적 평면에 흑백의 음영으로 표현하는 검사이다. 뿐만아니라 이들 구조물들이 전후, 좌우로 겹쳐져 있어 병변이 쉽게 가려질 수 있고, 폐실질 질환 뿐만 아니라 심장 질환 또한 폐실질의 변화를 유발시킬 수 있으므로, 단순히 각 질환의 X-선 소견에 대한 지식을 습득하는 것보다는 병인과 해부학적인 지식에 대한 이해를 기본으로 X-선 판독에 임하는 것이 중요하다. 또한 환자들의 임상 증상과 부합되지 않는 X-선 소견이 관찰되거나, 치료 도중 임상 경과와 판독소견이 일치되지 않는다면 방사선과 전문의와의 긴밀한 의견교환이 진단과 치료에 중요하리라 생각된다.

''소비자는 통상 매스컴에서 많이 다루고 있는 식품중 잔류농약, 항생물질이나 방사선 조사식품에서 대한 우려를 많이 하고 있다. 그러나 식품과학적 측면에서 이와같은 오염물질에 의한 위해발생 가능성은 별로 높지않다. 오히려 우리가 별 문제가 없다고 생가가하고 있는 식품중 미생물의 증식이나 영양적 불균형이 더 큰 위해발생 요인이다.'' ''발생가능한 모든 위해를 완전히 차단하는 것은 현실적으로 불가능할 분만 아니라 국민건강상 더 큰 위해를 초래할 수 있다. 그러나 대부분의 국민들은 단순히 적은 가능성일 뿐인 위해발생에 더 관심이 많고, 그 실익에 대해서는 모르거나 현실상황을 외면하는 경우가 많아 식품위생행정에 대한 불신이 증폭되고 있다. '' 최근 산국식품연구원의 송인상 박사는 한국농촌의학회지를 통해 발표한 $\ulcorner$식품의 안전성 확보를 위한 과제들$\lrcorner$이란 주제에서 이같이 지적하고 식품위생에 대한 보다 정확하고 과학적인 지식을 소비자에게 제공하는 교육과 홍보의 기능이 매우 중요하다고 주장했다. 주요내용을 발췌 소개한다.

The medical institutions use radiation generating devices and radioactive isotopes to diagnose and treat patients. The patient transporter performs work in an environment that is more likely to be exposed to radiation when compared with the general public, such as inevitably entering the radiation management area for patient transfer, or transferring the isotope-administered patient at a short distance. For this reason, we conducted a study to determine the degree of exposure of the patient transporter. The 12 patient transporters working at Incheon A General Hospital are eligible. From April 1, 2019 to April 30, 2019, the dosimeter was used in the chest for one month and the accumulated dose was measured. The dosimeter used was a Optically Stimulated Luminescence Dosimetry (OSLD) and the dose reading was OSLD Microstar Reading System. As a result of cumulative dose measurement for one month, the average of the deep dose was 0.13 mSv and the surface dose was 0.13 mSv, and the cumulative dose for one month was multiplied by 12 to estimate the cumulative dose expectation As a result, the average of the deep dose and the surface dose were 1.52 mSv and 1.51 mSv, respectively. It is necessary to classify the patient transporter as a frequent visitor in order to measure and manage the exposure dose, increase the knowledge of protection against radiation through education and training, and prevent radiation trouble through medical examination.

악안면 형성과정의 이상으로 인한 구조적 결함상태로 정의되어지는 악안면 기형(maxill-ofacial ogtal malformation)은 사고나 기능적(funct-ional) 장애로 인해 후천적으로 생길 수도 있으나 유전적 원인 등으로 인한 선천적 경우도 많다. 특히 후자의 경우에는 여러 증후군과 결합되어 나타나는 수가 많다. 치과의사는 치아이상이나 기능적 이상으로 인한 기형의 치료 및 예방을 담당할 책임이 있으며, 더욱이 새로운 진료실에서 직접 대면할 수 있는 최초의 의사가 될 수 있다는 점에서 특별한 기형외에도 전반적인 증후군에 대한 지식을 갖는 것이 중요하다. 악안면 기형환자에게는 전반적 검사가 필수적이며 방사선 분석, 치아모형 분석 등 다양한 분석이 필요하나, 여기에서는 주로 병력 청취나 시진을 통한 검사에 중점을 두어 서술하고자 한다.
