  • Background: This study used text mining techniques to determine public perceptions of dental fear, extracted keywords related to dental fear, identified the connection between the keywords, and categorized and visualized perceptions related to dental fear. Methods: Keywords in texts posted on Internet portal sites (NAVER and Google) between 1 January, 2000, and 31 December, 2022, were collected. The four stages of analysis were used to explore the keywords: frequency analysis, term frequency-inverse document frequency (TF-IDF), centrality analysis and co-occurrence analysis, and convergent correlations. Results: In the top ten keywords based on frequency analysis, the most frequently used keyword was 'treatment,' followed by 'fear,' 'dental implant,' 'conscious sedation,' 'pain,' 'dental fear,' 'comfort,' 'taking medication,' 'experience,' and 'tooth.' In the TF-IDF analysis, the top three keywords were dental implant, conscious sedation, and dental fear. The co-occurrence analysis was used to explore keywords that appear together and showed that 'fear and treatment' and 'treatment and pain' appeared the most frequently. Conclusion: Texts collected via unstructured big data were analyzed to identify general perceptions related to dental fear, and this study is valuable as a source data for understanding public perceptions of dental fear by grouping associated keywords. The results of this study will be helpful to understand dental fear and used as factors affecting oral health in the future.

  • This study is to investigate how do elementary students' eye movements appear in cognitive process that they perceive science learning materials depending on motivation system of science learning. For this study we had a random sampling of 301, 6th grade students. And we had selected 32 students through the three tests for the final; motivation system test of science learning, a learning styles test, an Edinburgh inventory for handedness test. We were analysis the cognitive process during learning tasks for the selected student using eye-tracking equipment. The results of the research are as follows: First, when students see a science learning material, we found out that SL-BAS group that has tendency searched various areas than SL-BIS group in learning task. Second, results confirmed through the data of integrational count that students looked alternately texts, images and graphs in the learning material, SL-BIS group were more than SL-BAS group on integrated count, but they had a simple and insignificant eye movement. Especially SL-BAS students showed that integrated eye movement between texts, images and graphs in the learning material, and they explored important areas of the graph compared with SL-BIS group that there was no eye movement in graph. These results may be utilized as a useful resource for designing students' learning.

  • 교과서를 통한 학습의 효율성을 최대화하기 위해서는 교과서에 수록된 텍스트 특성이 예상된 학습자의 특성(i.e., 언어적 및 인지적 능력, 배경지식 수준)에 따라 체계적으로 조절되어야 한다. 이에 따라 현재 연구에서는 과학교과서 개발에 이러한 체계적인 원칙이 반영되어 있는지를 알아보기 위하여 중학교 1, 2, 3학년 과학교과서의 학년 간 언어적 특성을 비교 분석하였다. 구체적으로 한국어 분석 프로그램인 Auto-Kohesion 시스템을 활용하여 기존 텍스트 분석 연구에 많이 활용되었던 텍스트 표층 구조 측정치, 어휘 관련 측정치, 통사적 복잡성 측정치와 같은 피상적 측정치에 더하여 여러 정합성 관련 측정치(e.g., 명사 반복, 접속사, 대명사)를 분석하였다. 주요 분석 결과, 대체로 어절 및 문장 길이, 어휘 빈도와 같은 피상적으로 두드러지는 특성에 대해서는 학년이 증가함에 따라 텍스트 복잡도가 상승하는 방향으로 단계적으로 조절이 이루어졌지만, 그 외의 많은 언어적 특질에 대해서는 체계적으로 조절되지 않은 것으로 나타났다. 특히 여러 정합성 측정치들이 교과서 개발 과정에서 충분히 고려되지 않은 것으로 시사되었다. 이러한 결과는 저학년 학습자들이 교과서를 사용할 때 발달 단계에 맞지 않는 어려운 텍스트를 접할 가능성이 있어서 학습 의욕 및 효율성 저하 현상이 발생할 수 있다는 것을 제시한다. 아울러 고학년 교과서가 고등 교육을 대비하여 더욱 복잡한 텍스트를 처리할 수 있는 능력을 개발시키기 위한 용도로 적절하지 않을 수 있음을 시사한다. 본 연구는, 추후 교과서 개발 과정에서, 예상된 독자 특성의 변화에 따라 정합성 측정치를 포함한 여러 언어적 특성이 단계적으로 조절되어야 함을 제안한다.

  • Objectives : The objective of this paper is to review the healing processes employed in the traditional age and discover the unique features found in the Korean Medicine through categorizing and analyzing the distribution of patients, and the aspects and results of treatments as recorded in Gyeongbosinpyeon, a historical text thought to have been authored by a regional doctor active in Joseon during the mid- to late-19th century. Methods : A table is created to view all of the total of 141 medical records introduced in the Gyeongbosinpyeon, and 7 categories were created to each contain 2 to 3 medical records that have special images. The paper provides their translation texts along with the original texts, and analyzed their medical and social significances by comparing each medical record. Results : The clinical competence displayed by the doctor who had worked in Joseon during the 19th century was surprisingly high, and it seems its values are worthy of dissemination when compared with Yeogsimanpil that has been introduced to the world. There is a great significance in how the principle of holistic treatments, the fundamental aspect of Joseon's medical study, was adhered. Additionally, the parts that show the historical text's author's medical activities and their unique characteristics are also worthy of attention. Conclusions : Korean medicine possesses a remarkable text called Donguibogam, but clinical behaviors' successes are not guaranteed solely with textual knowledge. It can be witnessed that such texts of authority and such medical records that have recorded actual activities complement each other in order to improve the quality of Joseon's study of medicine.

  • 이 연구의 목적은 한국 중등학교 과학 교과서에 기술된 화학적으로 불분명한 ‘중금속' 용어에 대해 정의, 종류 및 의미의 항목으로 알아보았다. 예비 결과에 의하면 교과서중에서 ‘화학 I' 교과서 8종 중 6종에 서 비중을 근거로 중금속을 정의하고 있으며 또 인체에 유해하고 지속적으로 축적되는 금속으로 묘사하고 있 다. 특히 8종의 모든 교과서에서 중금속의 예로 카드뮴, 납 그리고 수은을 제시하고 있으나 비소와 같은 비금 속이나 크롬, 망간, 철, 코발트, 니켈 그리고 구리 같은 인체 필수 미량 금속도 들어 있었다. 금속의 독작용을 이해함에 있어서 금속의 산화상태, 생체 내 존재량, 생체 성분과의 반응성을 고려해야 하지만 교과서에서 이에 대한 단편적인 예만 제시하고 있었다. 화학적으로 정의되지 못한 용어는 학생들로 하여금 중금속은 독소와 동 일할 수 있다는 대안 개념을 유발시킬 수 있으므로 이러한 모호한 정의와 설명은 교과서에서 지양되어야 한다.

  • Objectives : To identify differences in perspective between "Jinguiyuhanjing" and "Songbenshanghanlun" in regards to Baihutang and Baihujiarenshentang through comparative analysis of relevant verses of the two texts. Methods : Comparative analysis was undertaken based on the hypothesis that the two texts are relatively unrelated to each other in their transmission. Relevant verses were examined to identify their differences, followed by analysis of the overall context based on these variations to determine the difference in perspective between the two texts. Results & Conclusions : While in "Songbenshanghanlun" the relationship between the two patterns were ambiguous and conflicting at times, in "Jinguiyuhanjing" the relationship was clear-cut, and similar patterns that could be mistaken were systematically explained. From the perspective of "Songbenshanghanlun", the key traits of "Jinguiyuhanjing" could be summarized into two. First, in "Songbenshanghanlun", it says that if there are exterior symptoms, Baihutang cannot be applied, which naturally excludes Baihujiarenshentang. However in "Jinguiyuhanjing", exterior symptoms constitute the Baihujiarenshentang pattern. Second, in "Songbenshanghanlun" contraindication of Baihutang concerning miscellaneous symptoms are reduced in the form of footnotes which meaning is unclear, while in "Jinguiyuhanjing" the three points of contraindication of Baihutang are listed separately under verse no. 170, with relevant verses listed organically, explaining in great detail the Baihutang pattern, its relation to similar patterns and treatment.

  • Scene text recognition has important application value and attracted the interest of plenty of researchers. At present, many methods have achieved good results, but most of the existing approaches attempt to improve the performance of scene text recognition from the image level. They have a good effect on reading regular scene texts. However, there are still many obstacles to recognizing text on low-quality images such as curved, occlusion, and blur. This exacerbates the difficulty of feature extraction because the image quality is uneven. In addition, the results of model testing are highly dependent on training data, so there is still room for improvement in scene text recognition methods. In this work, we present a natural scene text recognizer to improve the recognition performance from the feature level, which contains feature representation and feature enhancement. In terms of feature representation, we propose an efficient feature extractor combined with Representative Batch Normalization and ResNet. It reduces the dependence of the model on training data and improves the feature representation ability of different instances. In terms of feature enhancement, we use a feature enhancement network to expand the receptive field of feature maps, so that feature maps contain rich feature information. Enhanced feature representation capability helps to improve the recognition performance of the model. We conducted experiments on 7 benchmarks, which shows that this method is highly competitive in recognizing both regular and irregular texts. The method achieved top1 recognition accuracy on four benchmarks of IC03, IC13, IC15, and SVTP.

  • The purpose of this study was to identify the preferable motivation types in science-learning and to find out the relationship between these types and scientific achievement of students in the secondary school. The subjects of the study were the second grade 581 students sampled by random cluster sampling method in three middle schools and three high schools. Three motivation types in science learning were analyzed, and they were named to task-orientation, ego-orientation and work-avoidance. From our results, secondary school students preferred task-orientation and work-avoidance to ego-orientation. In the case of task-orientation, high school students, especially in male group, had much preferable tendency than that of middle school students (p<0.001). It is interpreted that, as the level of scientific content of texts or the cognitive level of students were higher, a preference for the motivation type was focused to the task-orientation, especially in male group. In the case of ego-orientation, the female group showed much preferable tendency than that of male group in middle school (p<0.05). However, the female group in high school students was not different from the other groups in this motivation type. In the case of work-avoidance, there were not only a significant difference between males and females in the middle school (p<0.001), but also difference between middle and high school students in female group (p<0.05). It showed that female group had much preferable tendency than that of male group, and this tendency was decreased to the higher grade students in secondary school. From the analysis of correlation between motivation types and scientific achievement, task-orientation and work-avoidance were correlated to the scientific achievement. Its results were interpreted that the scientific achievement could be accomplished by the external motivation stimulus as well as the scientific content of texts. The task-orientation were comparatively correlated to the intelligence quality. It means that the students having high intelligence quality showed much preferable for the task-orientation.
