  • The purpose of this study was to identify and compare the types of scientific questions which were generated by elementary students and preservice teachers on the tasks of scientific observation. To identify the types of scientific questions, 4 observing tasks, dry grapes contained in soda pop, candlelight, celery, and a rock were administered to 40 sixth elementary students and 20 elementary preservice teachers. And then, the types and frequency of scientific questions generated by them were compared. The results showed that the types of scientific questions were classified into conjectural questions, causal questions, predictive questions, methodical questions and applicative questions. Further more, subordinate questions to the above questions were classified into object exploration questions and object verification questions, explicans exploration questions and explicans verification questions, result exploration questions and result verification questions, example exploration questions and example verification questions. Subordinate questions did not come out from the methodical questions. The types of scientific questions generated by elementary students and preservice teachers were identical, however, there were differences in frequency. This study supports that elementary students also have cognitive capability to generate various scientific questions. The results of this study may be used as a teaching strategy for the guidance of the direction and the method of scientific inquiry.

  • The purpose of this research was to examine the concept of elementary school teachers of combustion. The participants were selected from the elementary school teachers who had various career experiences, 6th grade science teaching experiences, and academic backgrounds on science. For the purpose of this study, 12 elementary school teachers took the concept-test formed five questions on combustion and were interviewed. The concept-test was composed with 'The definition of combustion', 'The reason that the candle was blown out when glass was closed.', 'The existence of oxygen and carbon dioxide of before and after combustion in glass', 'Combustion of iron', 'Combustion products'. And the collected data by semi-structured interviews based on responses to the concept-test. During the analysis of the data, additional interviews by phone, e-mail and Internet messenger were conducted if necessary. The answers to each question were classified into three levels: (Scientific-concept(S), Partial-concept(P), Misconcept(M)). The research results showed that all teachers had misconceptions or partial-concept of more than 50 percent of each question. Teachers who had the 6th grade science teaching experience acquired scientific concepts of the combustion more than teachers who did not have the 6th grade science teaching experience. We should develop visualization materials about the change of gases during combustion and use these materials for implementation of the scientific concept.

  • The purposes of this study were to develop the experiment for gas concentration measure during combustion of a candle and to investigate the application effect of the experiment. For this study, 15 elementary school teachers were selected by considering their gender, career, 6th grade science teaching experience, and 6th grade science teaching experience according to 2007 revised s cience curriculum. The experiment using MBL is designed to confirm gas concentrations visually during the combustion of a candle which burns in an acrylic container. The experiment method is as follows. 1) Make two sets of holes in the container and then insert oxygen sensors and carbon dioxide sensors in the holes. 2) Burn a candle in the container and observe the changes in the burning of the candle. The experiment has checked oxygen concentration and carbon dioxide concentration in real-time and displays gas concentration changes by graphs. The results of the application effect of the experiment are as follows. Most elementary school teachers who had not had scientific concepts on combustion got acquainted with scientific concepts about ‘the reason why a candle is blown out when it is covered with a bottle’, and ‘the concentrations of oxygen and carbon dioxide before and after combustion’. In addition, about half of elementary school teachers got acquainted with scientific concepts about ‘the definition of combustion’, and ‘distribution of carbon dioxide during combustion’. Thus, the experiment to measure gas concentrations during combustion is helpful to improve elementary school teachers’ concepts on combustion.

  • The purpose of the study was to investigate the effect of observation knowledge generation based on a scientific observation strategy in 6th grade students. In this study, we selected the topics related to the observation in elementary science curricula and developed worksheets and guidelines such that subjects accomplished the systematic observation based on the method and strategy of the observation knowledge generation. Seventy-five 6thgraders, 38 for the experimental group and 37 for the control group, were chosen for this study. The experimental group was taught the science lessons with 14 sessions based on the generation of various scientific observation types, whereas the control group was provided with traditional lessons. Before and after the treatment, a candle-burning task was set for subjects to test the effect of the lessons of scientific observation knowledge generation. According to the results, subjects in the experimental group were more effective in the generation of various observations than subjects in the traditional one. The observation abilities of the experimental group was shown statistically to have a significantly higher performance in richness and the diversity. In addition, they showed higher scores in the scientific observation ability task than the control one. Therefore, the systematic lesson strategy in scientific observation is presumably effective to improve students' ability of scientific observation knowledge generation.

  • The purpose of this study was to apply the microgenetic analysis method for development of information on an individual's change in a certain area during a consistent time period to seek change in scientific questions that elementary school students create. The study subjects were six 6th graders in I elementary school located in Kyunggido with the students conducting 6 sessions of two observational tasks about dry grapes contained in soda pop and candlelight. Information were collected through students' scientific question development paper, record of field observation and interviews. The results of this study are as follows: first, the number of scientific questions that the elementary school students developed showed a tendency for reduction; second, the changes in type of scientific questions bring different results, which depend on a particular characteristic of the tasks; third, By observing pattern changes in scientific questions of each individual, it was found that different results show for each time for the same task, which in other words means that there exists variability within an individual. Also, variability between individuals were shown by confirming that the change pattern for each person were diverse. Thus, the result of this study shows the following implications on education of scientific question development. For students, scientific question development mean more opportunities to increase the process of developing and acquiring knowledge. Therefore, it is important to create situations where one can come up with scientific questions. In addition, analysis in tasks' nature when selecting tasks would be necessary to develop diverse scientific questions.

  • This article adapts the democratic approach to the National Archives System. We must now search for a new archival landscape. Authors are agreeing that democracy is a basic principle for the new national archives model. This research looks into the direction of reform of the national record organizations in terms of individuality, integrity, and professionalism. It is, the fact that there are discussions rising on the need to reform the national records organization in the recent perspective of democracy. Democracy is a system that takes responsibility of even the results. This article describes all the discussions on what the best model for national archives system could be. In this social regulation, the archives carry out a noble mission of accountability. The discussion that suggests a clear perspective of democracy must be taken in to notice. Authors try to represent the voices of records managers. They also argue that records managers are the common wealth for our society. The national archives system is now the signature for the moral identity of national ruling powers. We argue that the new archives model should be derived from the point of the Candle Revolution.

  • This paper analyzes the structures and issues of 2018 Korean local elections based on the author's observations on the electoral processes. Even if this paper does not follow a traditional statistical method, it provides the interpretative meanings of 2018 local elections by utilizing an expert's observations of campaign processes. This result of 2018 election can be summarized into two analytical frames. In terms of electoral competition structure, three key factors, such as presidential approval rating, party competition structure, ideological spectrum, tend to affect the winning of governing party. In the light of election issue, the inter-Korean summit, the Washington-Pyeongyang summit, Incheon deprecating remark were positive to the vote gains of governing party, but the negative campaign, the drucking scandal and the swing voters were found not to be significant. The local election in Korea tends to show dual meanings, a proxy war of national-level politics and a composition process of local government. This paper found that the 2018 election has dual meanings at the same time, in a sense that it is the punishment of the ex-governing party's wrongdoing and the power change of local government.

  • The popularity of melodrama indicates that melodrama is composed in a historical context. This is the reason why it is necessary to analyze the imagination of melodrama within a sociocultural context rather than asking the essentialistic question of "What is melodrama?". (2016) and (2018) caused sensations while holding unchallenged top positions in terms of viewing rate and popularity. These dramas indicate the popular imagination and desire of Korean society in the 2010s during a period of upheaval. This paper analyzed imagination in melodrama with a focus on nation and emotions of individuals in and . In preexisting dramas, conflicts are often limited to individuals and families; on the contrary, in and , a nation appears as a motif that forms conflicts between individuals. In these intense situations of conflict, people make rational judgments at first; however, they soon dispose of such judgments and reveal value-oriented attitudes through emotions, which drive actions. Both dramas form poésie mainly through poetic rhyming and the mise-en-scène of objects. The dramas also amplify emotions. The main emotions of these dramas are sympathy and sadness. Such emotions are not consumed in itself; instead, they show moral aims through performativity. Consequently, sympathy becomes solidarity, and sadness becomes mourning. Unlike preexisting melodramas whose endings were simply pursuits of love and happiness within the realm of individuals, and demonstrate a moral imagination that simultaneously reminds us of the individual and community through solidarity and mourning.

  • This study explores the creation and enjoyment of Kuwoonmong (九雲夢) using a reference system called the cultural imagination, which is related to the Yin-Yang (陰陽) and Wu Xing (五行). When Kim Manjung wrote Guwoonmong, he may have composed figures and events based on this imagination. In particular, when he designed the eight seonnyeo (팔선녀), he set the order such as Gap (甲), Eul (乙), Byeong (병), Jeong (丁), etc. and characterized them according to the celestial stem (天干). Thus it was easy to avoid overlapping of characters and to construct various stories and relationships between them. The table below shows the characters of Kuwoonmong corresponding to the celestial stem. In not only the individual person but also the narrative world, Kuwoonmon demonstrates Yin-Yang and Wu Xing's imagination. In this respect, Kuwoonmon can be considered a large symbol encompassing the abstract theory of Yin-Yang and Wu Xing. Of course, the writer, Kim, Manjung would not have tried to symbolize the principle intentionally. However, he was also present in the environment of the cultural imagination that has been formed over the years. The same is true for the contemporary recipients of Guwunmong. They would have had a pleasant experience applying the cultural imagination and strengthening their familiar world view and human view.
