  • Relevance judgment is important in terms of improving the effectiveness of information retrieval systems, and it has been dominant for users to search and use images utilizing internet and digital technologies. However, in the field of image retrieval, there have been only a few studies in terms of identifying relevance criteria. The purpose of this study aims to identify and characterize the non-relevance criteria from the failed image searches. In order to achieve the purpose of this study, a total of 135 participants were recruited and a total of 1,452 criteria items were collected for this study. Analyses and identification on the data set found thirteen criteria such as 'topicality', 'visual content', 'accuracy', 'visual feature', 'completeness', 'appeal to user', 'focal point', 'bibliographic information', 'impression', 'posture', 'face feature', 'novelty', and 'time frame'. Among these criteria, 'visual content' and 'focal point' were introduced in this current study, while 'action' criterion identified in previous studies was not shown in this current study. When image needs and image uses are analyzed with these criteria, there are distinctive differences depending on different image needs and uses.

  • This study is based on the importance of observation or exploration in contemporary scientific inquiry and the need to expand the learning materials of science inquiry. It aims to analyze students' characteristics of exploration in abduction by developing and applying an educational program using art materials. For this study, a program named "Scientist going to the museum" utilizing artistic materials such as Oriental and Western paintings, mythology, orchestral suite, and traditional houses, was developed and five middle school students participated. Students who found and explored interesting phenomena in the work were divided into three main groups depending on the characteristics of the exploration activity. Some students observed and described elements that could be connected to scientific concepts, while others mainly explored everyday elements that were relatively unrelated to such concepts. Moreover, another type of students explored the works based on their subjective evaluations. This study shows that learning materials that cannot be visually explored are not suitable for abductive activities that students' prior knowledge has a significant impact on their exploration, and that educational materials for earth science inquiry could be expanded. This study also provides an example of learning materials and methods, and that abduction may be utilized for learning astronomy.
