The purpose of the study is to develop an online measurement scale for diagnosing self-directed learning ability for students in Korea. In order to achieve the goal, literature review, case analyses, and experts interview were carried out and finalized the blended-learning based SMMIS model. A total of 1,626 elementary, middle and high school students participated in the scale survey to validate the credibility and validity. Based on these results, an online measurement tool for self-directed learning was developed. The tool can be used in blended-learning environment to maximize its effectiveness. In conclusion, we discussed about implications and strategies for the blended-learning based on self-directed learning program model for young students, and suggested future vision and further research.

The present study aimed to develop an instrument to assess young children's understanding of science inquiry skills. For the purposes of the study, based on analysis of literature and evaluation tools related to young children's science inquiry skills, five categories of understanding science inquiry skills including observing, classifying, predicting, measuring, and discussing were selected. Then 30 test items were developed and verified three times through opinions from science education and early childhood education professionals and teachers. Finally, a total of 19 test items within five categories were developed. The 19 items' item difficulty, item discrimination, and item internal consistency were verified statistically. In addition, concurrent validity and test-retest reliability of the items were verified by the significant correlation coefficients. The instrument developed in this study was administered to 300 children who were 3, 4, and 5 years old. The results showed that 5 year old children had better competence to understand science inquiry skills than 4 and 3 year old children, while there were no differences in the competence between boys and girls.

With the advent of an intelligent information society, research toward artificial intelligence education was conducted. In previous studies, the subject of research is biased, and studies that analyze attitudes toward artificial intelligence are insufficient. So, in this study developed a test tool to measure the artificial intelligence of high school students and analyze their attitudes toward artificial intelligence. To develop the test tool, 229 high school students completed a preliminary test, of which the results were analyzed via exploratory factor analysis. To analyze the students' attitudes toward artificial intelligence, the resulting test tool was applied to 481 high school students, and their test results were analyzed according to factors. From the study's results, there was no difference according to gender in the students' attitudes toward artificial intelligence, but there was a significant difference per grade. In addition, there was a significant difference in attitudes according to artificial intelligence-related experiences: the high school students who had direct and indirect experience with artificial intelligence, programming, and more frequently used it had more positive attitudes toward artificial intelligence than students without this experience. However, artificial intelligence education experience negatively influenced the students' attitudes toward artificial intelligence. Overall, the higher their interest in artificial intelligence, the more positive the high school students' attitudes toward artificial intelligence.

동일한 작업환경과 작업조건을 가정하였을 때, 사고가 발생할 확률은 작업장에서 일하는 모든 사람들에게 거의 균등하다. 그러나 현실은 다른 사람들과 달리 특정하게 사고를 많이 발생시키는 사고 빈발자가 존재한다. 본 연구는 항해사 인 적성 평가도구를 개발하기 위한 기초단계로 항해사의 운항적성 중 지각 운동 영역에서의 운항적성을 평가하고자 하였다. 항해사의 지각 운동 영역에서의 운항적성 평가를 위해 CBT(Computer-Based Test)의 형태로 항해사의 지각 운동 영역을 측정하고자 하였으며, 지각 운동적 기능이 복합적으로 작용되는 항해의 특성 상 복합적인 측정이 가능한 형태로 검사를 구성하고자 하였다.

This study searched the perception of observational evaluation system in visual art which elementary and middle school teachers have in mind. As results, observational evaluation system in visual art is widely accepted as important and efficient to diagnose the artistic giftedness. At the same time, subjectiveness of the system might be advantageous for student for whom teacher get favor and in-service program related to observational evaluation system is insufficient comparing to the demand from field. In spite of this, the scale for behavioral characteristics of the gifted in visual art and the test for artistic task performance are recognized as the most important and needed tools for evaluating artistic giftedness. Following the results, in order to raise up the validity and reliability of evaluation in visual art, the scales for behavioral characteristics of the gifted in visual art and the test for artistic task performance should be developed first and foremost.

국내 산업화가 들어선 후 산업화 당시 지었던 낙후된 건물의 증가에 따라 구조물의 손상 조사 및 검사 방법의 수요가 늘어나고 있다. 일반적으로 구조물의 손상은 전문 검사원이 현장에서 직접 측량도구와 시각적인 방식으로 검사한다. 그러나 전문 검사원들이 직접 조사하는 수고에 비해 균열을 검사하는 방식 자체가 단순하고, 일반 사람이 검사하기에는 객관성이 떨어지는 한계가 있어 균열을 자동적으로 검출함으로써 객관성과 편의성을 보장할 기술이 필요하다. 본 연구에서는 이미지 기반으로 다양한 환경에서의 외벽 균열을 검출할 수 있는 딥러닝 모델 개발을 소개한다. 균열 검출을 위해 다양한 외벽 균열 관련 데이터셋을 확보 및 구축하고 각 데이터셋의 검출 정보를 보완할 반자동(semi-auto) 라벨링 작업을 수행하였다. 두 번째로 기존 높은 검출 성능을 보였던 모델들을 선정 및 비교하여 YOLO v5 모델을 최종적으로 선정하였고, 도메인이 각각 다른 데이터셋에 대한 교차 학습을 통해 각 데이터셋의 mAP의 편차가 31%에서 11%로 좁히는 작업을 수행하였다. 이를 통해 실제 상황에서의 균열 영상에서 균열을 검출할 수 있는 측량 시스템을 개발함으로써 실질적인 검사의 도구로 활용될 수 있길 기대한다.

후두기능의 전기생리학적 특징에 대한 관심은 1940년대부터 시작되어 1950년대와 1960년대에는 유럽 및 일본에서 Faborg-Anderson, Hirano 등이 후두근전도의 임상적 적용에 대해서 보고한바 있으며, 1970년대부터는 미국에서도 Bleir, Miller등이 후두근전도의 임상적 역할에 대해 보고하고 있다 이와 같이 후두근전도가 임상에 도입된 지 오래되었고 신경후두학 분야에서 후두근육의 전기생리상태를 알 수 있는 아주 중요한 진단도구이나 아직까지 후두근전도는 양적인 평가가 가능한 표준화된 검사는 아니고 내시경이나 방사선학적 검사처럼 경험이 있는 의사에 의해 판독되어지는 검사로 음성장애가 있는 모든 환자에서 집단검진(screening test)으로 이용될 수 있는 검사도구는 아니다. 후두근전도가 임상에서 유용하게 이용되고 있는 질환은 성대운동 장애와 연축성 음성장애이다. 최근 성대운동 장애에 대한 다양한 수술방법이 개발되면서 수술 방법 및 시기 결정, 예후측정에 후두근전도의 이용이 필수적이 되었으며 또한 연축성 음성장애 환자에서 어떤 후두 근육에 botulinum toxin을 주사할 지를 결정하는 데 이용하고 있다. 이번 강의에서는 위 두 가지 질환을 중심으로 후두근전도의 임상적 유용성을 살펴보기로 하겠다.

Purpose : To identify the correlation between CBS and pencil and paper test, and to test the sensitivity of above tests about unilateral neglect. Mostly used tool of pencil and paper test is line bisection and albert test. CBS is behavioral neglect test. Methods : The subjects of study were 44 stroke patients with left hemiplegia. Data were analyzed for Pearson correlation, paired t-test and ANOVA using SPSS program. The significance level was ${\alpha}<.01$. Results : The results of the study was as follow: 1. CBS had a significant correlation of line bisection and Albert test. 2. CBS was more sensitive than the pencil and paper in unilateral neglect. 3. CBS had high correlations with ADL than the pencil and paper test. Conclusion : The result showed that CBS was more useful than a pencil and paper test to distinguish unilateral neglect and available to diagnose anosognosia. Therefore, it should be considered applying CBS to inspect and cure unilateral neglect.

웹 접근성(Web Accessibility) 평가를 위하여 웹 접근성 표준 가이드라인에 기반 한 120여개의 자동화 평가 도구들이 존재한다. 국외 평가도구는 WCAG 1.0과 미국 재활법 508조를 기준으로 만들어진 A-Prompt, Bobby 등이 있으며, 국내에는 KWCAG 1.0에 기반하여 한국정보문화진흥원에서 제작한 KADO-WAH가 유일한 자동화 웹접근성 평가도구이다. KADO-WAH는 국외 평가도구와 비교하여 상세한 검사를 진행하지 않으며 자동화 평가 범위가 한정되어 있어 상당부분 전문가 평가를 필요로 한다. 이를 보완하기 위하여 개선된 웹 접근성 평가도구의 개발이 필요하다. 본 논문에서는 국내 자동화 평가도구인 KADO-WAH의 기능을 향상시키기 위하여 국외 자동화 평가도구와 비교 분석을 통해 KADO-WAH의 문제점을 제시하고, 이 문제점을 개선한 웹 접근성 평가도구를 구현한다.

This study aims to develop and validate Creative Problem Solving Profile Inventory (CPSPI) which is a scale to measure the creative thinking style, based on the CPS theory. For redeeming the limits of existing scales, this study developed an inventory which includes an evaluation for cognitive ability as well as cognitive preference and the stage to share an idea with others and persuade (Persuasion & communication stage). At the early stage, 7 factors (stages) and 82 items were developed and finally, 5 factors and 39 items were selected through item analysis and validation of construct validity. In conclusion, CPSPI will be used as an educational tool for self-development by knowing own's strengths and weaknesses in the creative problem-solving process, and help in displaying cooperative creativity by understanding other people and interaction, based on creative thinking profiles of group members.
