레이더 강우와 관련한 대부분의 연구나 실무적용이 제한을 받는 이유는 레이더 반사도 등의 원시자료를 획득하기가 어려울 뿐만 아니라 이를 처리하여 수문해석에 적용하는 과정이 간단하지 않기 때문이다. 이를 해결하기 위하여 다음과 같은 내용을 연구하였다. (1) 레이더 영상자료를 실용적으로 활용하기 위한 '레이더 영상 디지털 변환법(RAIDOM)'을 연구 개발하였다. 또한 오프라인상에서도 기상청 레이더 합성 CAPPI 이미지 자료를 디지털 강우자료로 직접 변환할 수 있는 방법을 제시하였다. 이러한 기술은 앞으로 레이더 강우 연구와 레이더 강우의 활용성을 넓히는데 크게 기여할 것으로 기대된다. (2) RAIDOM 레이더 강우와 연계한 분포형 강우유출모형을 구축하였다. 본 연구에서는 DEM, 토지피복도, 토양도로부터 분포형 강우-유출모형의 매개변수를 산정하는 방법을 상세히 연구하여 제시하였다. 이러한 연구결과는 앞으로 분포형 강우유출모형에 대한 연구와 활용성을 넓히는데 기여할 것으로 기대된다. (3) 주요 관측 레이더 호우사상을 이용하여 RAIDOM 강우와 구축된 분포형 모형의 적용성을 검증하였다. 이를 위하여 먼저 강우유출자료가 체계적으로 관리되고 있는 평창강 국제수문개발계획(IHP) 시범유역의 자료를 이용하여 모형의 매개변수 보정을 수행하였다. 강우 전 하천의 기저유량과 유역의 초기함수조건을 제외한 나머지 매개변수는 유역특성을 나타내는 인자들이므로 모든 강우사상에 대하여 일정한 것으로 가정하여 매개변수 보정을 수행하였다. 6개 주요 호우사상에 대하여 보정한 결과 4개의 호우사상에 대하여 강우-유출과정을 거의 완벽하게 재현하였으며, 2개의 호우사상에 대해서는 수문곡선의 상승과 하강은 비교적 일치하나 첨두부에서 다소차이가 발생하였다. (4) 보정된 분포형 모형을 2006년 7월에 발생한 국지성 집중호우와 한강유역 중상류지역에 걸쳐 큰 홍수량을 발생시킨 2개의 호우사상에 대하여 레이더 강우자료를 적용하여 검토하였다. 검토결과 임진강유역 3개 수위관측소와 우이천수위관측소 및 중랑교수위관측소에서 모의된 홍수수문곡선은 실측치와 잘 일치하는 것으로 나타나 본 연구에서 제시한 RAIDOM과 이를 적용한 분포형 모형이 강우유출 모의를 위하여 활용될 수 있음을 보여주었다. 앞으로 태풍에 수반된 강우와 장마전선 등을 포함한 다양한 유형의 여러 가지 강우에 대한 적용을 통하여 모형의 검증과 보완을 수행하여 RAIDOM 레이더 강우와 분포형 강우유출모형을 연계한 홍수 예보 시스템으로 발전시켜 나갈 예정이다.

The purpose of this study was to develop an inclusive dental hygiene practice model in an effort to stir up the self-directed learning of learners to boost their problem-solving skills and ability of providing inclusive personal oral health care in a systematic and efficient manner. The subjects in this study were 41 dental hygiene students who were in their second year in C college located in South Jeolla Province as of 2009. An inclusive dental hygiene practice was implemented during a 15-week period of time from August 31 to December 7, 2009, and a self-administered survey was conducted before and after that by using the same questionnaires. Whether there were any differences between before and after the application of the inclusive dental hygiene practice model was checked, and there was improvement in all the learning motivation, self-directed learning capabilities and satisfaction level. Concerning the relationship of academic standing to changes in learning motivation, self-directed learning capabilities and satisfaction level, the inclusive dental hygiene practice model brought more favorable changes to the students in the lower tiers. The inclusive dental hygiene model should be applied to not only practical courses but theoretical ones so that learners could make progress both in theory and practice, and evaluation tools geared toward assessing their academic achievement and practical abilities should be developed.

The aim of this study is to examine the effectiveness of non-face-to-face classes conducted due to the COVID-19 crisis. In order to achieve this goal, a non-face-to-face class with flipped learning was applied in one subject of clothing major held at 'S' University in Cheongju, Korea. In addition, this study tried to analyze the differences between pre- and post-non-face-to-face classes in problem analysis ability, resource/information/technology literacy, convergent thinking ability as core competencies, and overall learning satisfaction. As a result, after participating in the non-face-to-face class in which the flipped learning was applied, the students recognized that their abilities improved in the three problem-solving competency sub-areas, and their overall learning satisfaction also increased. The effectiveness of non-face-to-face classes in the field of clothing and fashion has been mainly measured in fashion design and clothing construction courses. However, based on the results of this study, it can be suggested that non-face-to-face classes in a theory-oriented lecture-type class can be effective methods for improving students' core competencies such as problem-solving skills if teaching-learning methods such as flipped learning are applied. Therefore, the results of this study will be useful data for designing differentiated non-face-to-face class strategies in a theory-oriented lecture-type class to improve the core competencies of college students.

The aim of this study is to identify the learning performance of online classes using problem-based learning(PBL) for clothing and textiles majors in college with the increased use of online learning tools after the COVID-19 pandemic. In order to achieve this goal, the PBL was developed and applied to the 'Fashion Marketing and Merchandising' class conducted in real-time online at University in North Chungcheong Province, Korea for four weeks. After a four-week PBL class, a survey was conducted on 35 students in the 'Fashion Marketing and Merchandising' class and the 35 completed questionnaires were used for analysis. The measurement tools of this study were self-directed learning, cooperative learning ability, problem-solving ability, and learning achievement regarded as an important learning effect in PBL class. In addition, students' self-reflective essays were also analyzed to examine the educational effect of PBL applying online classes. As a result of this study, bivariate correlations among the four variables, students' self-directed learning, cooperative learning ability, problem-solving ability, and learning achievement were significantly positive. Furthermore, the results of multiple regression analysis showed that the three independent variables had significant effects on students' perceived learning achievement, in the order of cooperative learning ability, self-directed learning, and problem-solving ability. The students' self-reflective essays indicated that problem-based learning worksheet was helpful for identifying problems, and clarifying what they already and what they need to study more. Based on this study, it could be recommended that online class applying PBL could contribute to the improvement of student's learning performance.

This study developed an 'Eco-friendly Clothing Life Cycle' class applying gamification. And the effect of and learners' satisfaction on the class were examined after implementation. The developed class was applied to 40 sophomore students from "A" high school in Gyeonggi-do from February 3, 2022, to February 10, 2022, in a total of 4 sessions. The class was conducted in the stages of production-distribution-consumption-disposal, and was conducted in a way that a mission is solved after learning in Gather Town. It is designed so that learners continuously repeat learning until they accomplish the mission. The learners completed pre-class and post-class questionnaires. And a focus group interview was conducted with a randomly selected group of three learners. According to the pre-/post-class test comparison, the gamification class on the theme of "Eco-friendly Clothing Life Cycle" was found not to have a significant effect on learners' immersion or self-directed learning attitudes. However, in the case of the learners with high levels of non-immersion tendency, the level of immersion in the class increased, and the satisfaction level was positively associated with the level of immersion and self-directed attitude. Learners expressed 'concern' and 'expectation' about the gamification class, and said that although the developed class was using a 'new teaching method', 'appropriate use' was necessary. And learners were evaluated this class as a 'student-centered class' and acknowledged that it allowed 'self-directed learning'. The teacher who implemented the class said that this class was more effective in attracting students' expectations and interests compared to the conventional classes, and that the class in the meta-verse environment was perceived as a new type of class in the non-face-to-face era. The teacher also mentioned that when applied to the actual educational field, a detailed design is needed that allows the learners to proceed smoothly, and the role of the teacher in the class was more important. And the teacher also mentioned that the class should be properly designed so that the expectations given by the 'game' do not obscure the essence of the class.

The current radiation safety management system is also applied to radiation practices at universities. The application of the law raised concerns about poor radiation practice education and hindering the development of radiology. Accordingly, the Korean Radiology Professors Association needed to grasp the reality of the management system for radiation practice education at each university and the current radiation safety management system in the department of Radiological science. So, a survey was conducted on heads of radiological science departments across the country. Through the survey, it was found that the current application of the Nuclear Safety Act to radiation safety management in the department of Radiological science is excessively restrictive and not very effective. In addition, radiology practice education for the purpose of training health and medical professionals should be controlled by the Ministry of Health and Welfare and the Korea Centers for Disease Control, but there is a problem of being supervised by the Nuclear Safety and Security Commission. Therefore, in this study, as a legal improvement plan to solve this problem, first, a plan according to a partial amendment to the Higher Education Act, second, a plan to be supervised by the Ministry of Health and Welfare through the amendment of article 37 of the Medical Service Act, third, article 20-2 of the Enforcement Decree of the Medical Service Technologists Act was newly inserted to propose three measures to be supervised by the Ministry of Health and Welfare.
