  • There is increasing interest in text analysis based on unstructured data such as articles and comments, questions and answers. This is because they can be used to identify, evaluate, predict, and recommend features from unstructured text data, which is the opinion of people. The same holds true for TEL, where the MOOC service has evolved to automate debating, questioning and answering services based on the teaching-learning support system in order to generate question topics and to automatically classify the topics relevant to new questions based on question and answer data accumulated in the system. Therefore, in this study, we propose topic modeling using LDA to automatically classify new query topics. The proposed method enables the generation of a dictionary of question topics and the automatic classification of topics relevant to new questions. Experimentation showed high automatic classification of over 0.7 in some queries. The more new queries were included in the various topics, the better the automatic classification results.

  • The purpose of this study is to investigate qualitatively two cases of general citizens' scientific participation and activities responding to fine dust problem. The processes of their scientific actions were investigated and categorized inductively based on three stages: problem recognition stage, information collection and analysis stage, and sharing and spreading stage. As a result, in the 'problem recognition' stage, two participants recognized the seriousness of the fine dust problem as they felt a threat to their health and began to act practically by questioning the accuracy of public data. In the 'information collection and analysis' stage, a participant collected as much information as possible and compared them in order to obtain more accurate information for her situation. On the other hand, another participant conducted various experiments in person to get the information which is appropriate to his situation. Finally, in the 'Sharing and Spreading' stage, both participants created and shared various materials based on online environment, and continued their activities with a sense of contribution through others assistance. Educational implications are discussed in terms of civic science education and scientific literacy.

  • The purpose of this study is to find out the direction of development of the expert diagnosis system by questioning student satisfaction after practicing Oriental Diagnosis System (ODS). A questionnaire survey was conducted for 73 students who attended Pusan National University Graduate School of Korean Medicine and conducted clinical practice from the second semester of 17 years to the first semester of 18 years. The questionnaire survey consisted of 6 questions about the satisfaction of current expert system and 5 questions about supplementation and addition. As a result of the questionnaire analysis, the question about the necessity of the expert diagnosis system and the benefit of clinical practice using the expert diagnosis system indicated high positive response rate. On the other hand, there is a difference in the results of the dialysis before and after using the expert diagnosis system. So, It seems that the reliability of the results of the expert diagnosis system is still low. The results of the questionnaire indicate that the need for expert diagnosis system is beneficial, but it is necessary to supplement the current system in order to improve clinical utility in the future.

  • Bernard $Dadi{\acute{e}}$ expresses virtue, justice, and goodness by mixing reality and fiction through the life of the spider Kacou $Ananz{\grave{e}}$ in The Black Cloth (le Pagne noir). In Black Africa folktale, especially $Co{\hat{o}}te$ d'Ivoire, virtue, justice, and goodness are important factors. The spider's life is full of imagination and tricks that reveal a variety of lessons: i) material abundance and frustration in the 'Spider and the Tortoise', ii) an autistic life that refuses to separate from the mother in the 'Spider's Hump', iii) leaving a trace of violating the taboo on the sheep in the 'Spider's Ox', iv) the failure of a ploy by hurting others to satisfy individual desire in 'The Dowry'. These diverse stories enable us to understand human characteristics and imperfections by questioning customs of society and value of customs, reinterpreting folktale, and clarifying instructional intentions.

  • Mobile GUI design is changing from an existing design that emphasizes intuitive cognitive effects to an affordance design that naturally triggers users' behaviors. However, in the GUI design, the current affordance only uses some partial design elements and cannot achieve effective design, and the concept of affordance design still has confusion and uncertainty. For this reason, this paper redefines affordance by examining the concepts and types of it in the pre-research. In addition, through questioning the type of affordance, a questionnaire was designed for the GUI elements of social software. According to the results of the survey, the evaluation of the affordance of the GUI design elements was derived, and the GUI design of the social software was compared and analyzed. Then according to the deep interviews, a GUI design proposal that can effectively use affordance was proposed.

  • The purpose of this study is to find out the effects of reconstructing unit 'Seasonal Change' using step-by-step questioning for concepts changes to adjusting misconceptions of elementary school students. Most students have pre-conceptions at describing seasonal changes based on their experiences. Therefore, in newly developed unit, we reconstructed unit to include core teaching and learning contents by finding out common pre-conceptions of students and specifying purpose of teaching at misconceptions found in pre-conceptions as 'constituent of class for conceptual change'. After the scientific concept test, the result of 24 students in experimental group is statistically significant. Also, according to the result of qualitative analysis, the number of activated conceptional resources and degree of specificity in explaining seasonal changes are higher than that of control group.

  • In this study, a block-base coding that could develop computing thinking was applied to Earth science teaching and learning to identify how the perception of computational thinking and scientific attitude was changed as part of creativity education. Based on the results of the study, the conclusions are as follows: First, an Earth science education program was developed using a block-based coding for elementary school students. The 12-hour program was designed for inquiry activities to encourage students to engage in various thinking by providing them with activity-oriented problems. Second, the Earth science education program using a block-based coding showed significant results in confidence in the use of a computer program, integrated learning with a computer, computational thinking, and problem-solving factors with computational thinking. Third, the Earth science education program using block-based coding showed significant differences in the categories of curiosity, criticism, cooperation, persistence, and creativity. It could be judged that it was effective for students in the process of questioning and trying to solve the problem themselves.

  • The purpose of this study is to scrutinize the characteristics of a teacher's discursive competence on the basis of mathematical competencies. For this purpose, we observed all semester-long classes of a middle school teacher, who changed her own teaching methods for the last 20 years, collected video clips on them, and analyzed classroom discourse. Data analysis shows that in problem solving competency, she helped students focus on mathematically important components for problem understanding, and in reasoning competency, there was a discursive competence which articulated thinking processes for understanding the needs of mathematical justification. And in creativity and confluence competency, there was a discursive competence which developed class discussions by sharing peers' problem solving methods and encouraging students to apply alternative problem solving methods, whereas in communication competency, there was a discursive competency which explored mathematical relationships through the need for multiple mathematical representations and discussions about their differences. These results can provide concrete directions to developing curricula for future teacher education by suggesting ideas about how to combine practices with PCK needed for mathematics teaching.

  • Plato's philosophical importance in western thinking history cannot be understated. Especially his dichotomy system became common to the European traditions of philosophical and scientific discourses by assigning principal value to the presence that is opposed to the absence. Since the ancient Greeks, the concept of presence has been expressed itself in number of ways such as God, Truth, Logos, and center. Derrida called this European thinking "the metaphysics of presence." In order to analyze logocentrism also called the metaphysics of presence in No Telephone to Heaven, I used the term, paralogy that Aristotle did not accept as rules of argumentation but that Lyotard revived it positively as the principle of reason. Lyotard's incredulity towards rationalist theory of modernism is that knowledge can never be certain. Without any ultimate validity, certainty is impossible. Nevertheless, as Fanon said, the colonial world is dominated with a traditional Manichaean world. As a result what remains to the colonized to establish their identities is that of an armed struggle towards the colonizer even though they know it results in the vicious circle of hatred endlessly. Cliff attempted to show this message in her text through the tragic heroine, Clare Savage. Cliff's another critique of modernism's rationalism is shown through the ambiguous sexuality of Harry/Harriot. In this novel, gender plays also a central role by questioning the traditional binary system of sexuality. In this paper, I deconstructed this traditional gender system in terms of Bulter's concept of performitivity. This study will give the text another layer of deconstructive interpretation echoing with the proverb, one tree cannot make a forest.
