As the number of single-person households increases, the consumption of bottled water is increasing. In addition, as the public’s interest in radioactivity increases, interest in the field of living radioactivity is also increasing. Since drinking water is an essential element in our daily life, it must be safe from radioactivity. In this study, gamma radiation of drinking spring water was measured and internal exposure dose evaluation was performed to determine its harmfulness. K-40 and uranium-based radioactivity analysis was performed through a high-purity germanium detector, and as a result, drinking water was detected somewhat higher than that of mixing water. Since there is no regulation on the natural radioactivity concentration in Korea, it was compared with the U.S. Environmental Protection Agency Drinking Water Regulations and World Health Organization standard. As a result, there were some items that exceeded standards. Internal exposure was evaluated according to the effective dose formula of ICRP 119. As the result was derived that a maximum of 1.17 mSv per year could be received. This result means that the dose limit for the general public may be exceeded, and it was judged that it is necessary to set an appropriate standard value and present a recommendation value through continuous monitoring in the future.

본 연구에서는 COVID-19로 인한 비대면 수업이 전면적으로 실시된 상황에서 학생들이 인식한 ‘좋은 수업’ 특징을 분석하고 각 요소들 간의 관계를 분석하여 비대면 수업 요소의 구조모형을 도출하고자 하였다. 본 연구 수행을 위하여 2020학년도 서울과 수도권, 충청도 및 경상남도 소재 7개 대학의 ‘좋은강의 에세이’ 혹은 ‘우수강의 에세이’ 총 117개의 자료를 분석하였다. 본 연구에 사용한 분석 방법은 질적연구 중 근거이론이었다. 본 연구결과, 개방 코딩에서 13가지의 요소가 도출되었으며 비대면 수업 요소의 구조모형 인과적 조건, 맥락적 조건, 중재적 조건, 상호작용 요인으로 구분하여 기술하였다. 비대면 수업요소 구조모형의 인과적 조건으로는 수업환경과 학습자 정서 요소, 맥락적 조건으로는 교수자 특성, 중심현상으로는 강의콘텐츠 구성전략, 수업구성전략, 학습촉진 전략, 과제구성 및 제시 전략, 평가전략 요소가 도출되었다. 중재적 조건으로는 피드백 전략, 작용/상호작용 전략으로는 상호작용 요인이 도출되었으며, 마지막으로 결과는 인지적 효과, 정서적 효과, 만족도 요소가 도출되었다. 본 연구결과는 비대면 수업설계, 수업 운영, 성과 목표 등의 강의 전략 수립의 기초 자료로 활용될 수 있을 것으로 기대된다. The purposes of study were to examine the characteristics of “best lecture” that students perceived under the circumstances of conducting full-scale non-face-to-face classes, and to analyze the relationships between each factor to draw a structural model for the factors of non-face-to-face classes. A total of 117 essays about high quality teaching at seven universities in the areas of Seoul, Gyeonggi-do, Chungcheong-do and Gyeongsand-do were analyzed. The method for analysis was based on the grounded theory. As a result of analysis, a total of 13 factors were identified using open coding and the structural model for the factors of non-face-to-face classes are as follows. This research draws the factors of the “class environment” and “affective elements of the learners” as a casual conditions of the structural model for the factors of non-face-to-face. It also draws the factors of “characteristics of instructor” as a contextual condition, and “the configuration strategy of class contents”, “instructional design strategy”, “learning facilitation strategy“, ”the task designing and presenting strategy“ and ”the assessment strategy“ as a central phenomenon. It also draws the factor of “feedback strategy” as an intervening condition, “interaction” factor as an action/interactions strategy, and the factors of “cognitive effect”, “affective effect“ and ”the satisfaction level“ as the last consequence. The results are expected to be used as a baseline data in establishing instructional strategy including non-face-to-face instructional design, class operation and performance goal.
