  • The purpose of this study was to analyze the factors that demographic factors, radiation knowledge level, and radiation awareness could be affecting the benefits of radiation. From July 2022 to July 2023, after receiving consent to participate by using the link of Naver through Social Network Service (SNS) for the general public, 312 people were surveyed by self-registration method without collecting personal information. The questionnaire consisted of a total of 25 questions following demographic factors (5 questions including age group by life cycle, sex, monthly household income, residence), radiation knowledge level (8 questions including basic physical, biological effects, radiation protection technology), radiation awareness (12 questions including risk, management, benefit). Independent sample T-test and ANOVA tests were performed for significant differences in the average radiation awareness between variables, and hierarchical regression was performed to identify influencing factors on radiation benefits. As a result, the benefit of radiation was significantly high among the radiation awareness, but the awareness of the danger of radiation was insufficient to the level of recognizing it as safe. Men had significantly higher awareness of radiation management and benefits than women, and the awareness of radiation management was significantly higher in the middle class with a monthly household income of 4.31 million won or more. The higher the knowledge level of radiation, the higher the awareness of the benefits of radiation. The factors that had a positive effect on radiation benefits were the high level of radiation knowledge and awareness of radiation management.

  • Objective: The purpose of the study was to explore early childhood teachers' content knowledge and knowledge level on unification education through an analysis of a concept map (Novak & Gowin, 1984). Methods: The subjects, including 65 early childhood teachers in a metropolitan area, were asked to draw concept maps illustrating their understanding of unification education for young children. The collected concept maps were analyzed using the methods utilized by Novak and Gowin (1984) as well as You and Kim (2018). Results: In terms of early childhood teachers' content knowledge, 282 superordinate concepts and 1,766 subordinate concepts were shown. The 282 superordinate concepts were categorized into 7 representative superordinate concepts: understanding of North Korean, understanding of separation/unification, identification as Korean citizen, unification policy, relationship between South Korea & North Korea, educational activities, connection with home and society. In terms of early childhood teachers' knowledge level, the numbers of subordinate concepts and hierarchical level were shown to be varied according to the 7 representative superordinate concepts. Conclusion/Implications: Discussions were included to support and enhance early childhood teachers' content knowledge on unification education for young children through the development of comprehensive programs and teacher education.

  • 입문기 아동의 수학 교육에서의 첫 걸음은 수 개념 형성으로부터 시작되는데 취학 전에 발달 단계나 학습 순차를 무시한 형식적인 수지도가 수 개념을 형성하는데 별다른 도움을 주지 못하는 것으로 나타나 있다. 수학 교과가 가지고 있는 논리적 위계성을 감안할 때 이전 학년에서 발생된 학습 결손이나 개념 이해부족은 다음 학년의 학습을 지속해 나가기가 어렵다. 이와 같은 학습의 과정이 반복되면 학습 부진을 증대시켜 학습에 흥미를 잃게 한다. 이에 본 연구는 수학과 기초 학습력을 신장시키며 취학 전에 발달단계를 무시한 잘못된 수 경험을 개선하고자 멀티미디어 웹 코스웨어인 '50까지의 수'를 설계 및 구현하였다.

  • 임상적으로 흔한 간질환인 지방간은 대부분의 경우에 초음파검사에 의해 진단이 된다. 초음파검사에 의한 지방간과 대장암의 전구병변이 될 수 있는 대장용종과의 관련성을 검진환자대상으로 일반요인과 대사증후군 요인 등 특정요인과 비교분석 하였다. 대장용종은 나이 50세 이상, 남자일수록, 공복시 glucose와 Triglyceride 수치가 높을 때, 지방간이 있을 때 발생빈도가 높았다. 상관관계분석에서는 지방간이 용종과의 관계도가 가장 높았고 위계적 회귀분석에서도 용종발생에 가장 영향력 있는 요인은 지방간이었다. 지방간인 경우 대장내시경검사를 고려해야 할 것이다.

  • This study aims to analyze the early 19th century Jeolla-Gamsa's(全羅監司; the provincial governor of Jeolla-Do) utilization of governing institutions in Jeonju-Bu(全州府) focused on his duties and ritual ceremonies. Wanyeong-Ilrok("完營日錄") which is Jeolla-Gamsa's official diary written by Yu-Gu Seo(1764-1845) is closely investigated for that purpose. As a result, it is proved that some governing institutions are used differ from ritual regulations.

  • 본 연구에서는 사례기반추론(case-based reasoning)을 기본으로 하여 실무자의 분류 기법 또는 분류 구조 결정을 돕는 의사 결정 지원 시스템의 모델을 제시한다. 주요한 네 가지 고려 항목은 자료종류(dataset), 위치(location), 기후(climate), 그리고 분류항목(class)이며 사용자는 이들 네 항목에 대해 적합한 값을 선택하게 된다. 본 시스템은 색인화(indexing) 규칙에 따라 관계형 데이터베이스에 저장된 사례들을 추출하여 제시하며 사용자는 그 중 가장 높은 일치도를 보인 사례들을 참고할 수 있다. 본 연구에서는 위계구조를 통해 다양한 분류 조건을 스크린 상에서 선택할 수 있게 함으로써 사용자가 이에 내재된 논리를 분류 구조의 설계에 반영할 수 있게 한다. 또한 Statistics 기능을 통해 여러 사례의 항목당 분포를 사용자가 검토할 수 있게 함으로써 가장 적합한 사례를 의사결정 지원 시스템과의 피드백을 통해 찾아낼 수 있게 해준다. 이밖에 분류 조건을 변화 시켜가면서 상황의 변화를 참고할 수 있도록 Navigation 기능을 고안하였다.

  • This study is to develop a learning program supporting how to teach multi-level of students in number and operating field in the elementary school. Mathematics requires different teaching ways for various standards of student in the school. However, in most of elementary school teachers are having hard time giving the proper lesson for each student due to the lack of supplementary classes and the excessive numbers of students in a class. Thus this research provides "Game-type learning Program" and supports individual learning lessons to give each student an opportunity to form a correct concept of number and operation. This system sets up suitable steps for each student by checking their leaning progress and accomplishment. When a student has a trouble, can give a help or show specific things which could be related with the matter. As a result, students have got more interests in studying math, furthermore, actually, the help and giving a clue helped students a lot in settling the problems.

  • The concept map is the diagram of two dimensions which hierachically arrays main concepts from those of the textbook and shows their relations. The research analyzed five of the ten high school earthscience textbooks approved by the Minister of Education according to the 6th reformed curriculum in 1995, one of which this research chose to make out the concept maps. The chapter [III. the Universe] contains the outer space of the earth presents new concepts about the stars and the universe and introduces the latest research in astronomy. This study changed textbook contents into Novak's concept map, searched for concepts requiring complement for learners in oder to obtain concepts from those of the textbook and pointed out problems on the basis of that result still better concept map is set up. We have the following conclusions. First, it is necessary to rule out unnecessary small units so as to make more effective understanding and to rearrange the units to have relation to contents. Second, the higher concept and lower concept need to be rearranged systematically in making an array of textbook contents. Third, the concept should have something to do with learners' experences and consciousness by showing learners the real examples relevant to the concept for the link between them.

  • This study aimed to verify the mediating effects of personality and job-seeking efficacy in the process of college students' career maturity affecting their career decision certainty level. To this end, an online survey was conducted with 254 college students attending domestic and foreign universities, which confirmed the mediating effect of job-seeking efficacy in the relationship between career maturity and career decision certainty level. In addition, the effect of career maturity on the level of career decision certainty, mediated by job-seeking efficacy, was shown to be controlled by personality, namely extraversion, confirming the moderate mediating effect of this variable. Based on these findings, the implications and limitations of this study are discussed.
