  • All architecture in the history were based on a certain concept of architectural unit that functioned as a base model of architectural design. As we know, such model was not the same in the East and the West, and therefore, their architectures are not the same. This paper aims to identify how and why such base model of the two cultural area are different. As one way of discussing this issue, the concept of particle and field, as two representative idea of the West and East respectively, the employed. This kind of discussion can not follow the way of scientific verification as method of argument. However, the understanding of such concept of unit model is crucial for the understanding of the architecture of the culture in general. In basic sense, the tradition of Western architecture is rooted in the model of particle, where, architecture is conceived to be as a independent unit standing on earth as if it is a box like object. While, the tradition of Eastern architecture is rooted in the model field, where, architecture is conceived to be a part of field organization. In present days, we are used to the model of particle as if it is the only possible model of architecture. But, in fact, what man need to achieve in their architecture and city, is the balance between the two models.

  • This study aims to identify the characteristics of the program that integrates maker education with science subjects and to explore the maker's competency expressed in students. To this study, a maker activity program based on scientific concepts was developed and applied to 20 first-year students at H University in a general chemistry experiment course, and activity data were analyzed. The analysis results of maker activities based on scientific concepts are as follows. First, students performed activities through the process of 'presentation of ideas,' 'selection and planning of ideas,' and 'prototyping'. In particular, it was confirmed that prototyping was divided into stages of "partial prototyping" and "full prototyping". Second, as characteristics of the activity, 'use of scientific concepts as logic for coding in the process of maker activities', 'in-depth understanding of scientific concepts', and 'inducing high achievement and interest through transfer of initiative in learning' were confirmed. Third, collaboration competency and making performance competency were frequently expressed in the process of activities, but human-centered competency were rarely expressed.

  • The paper presents some new results illustrating some developments related to the concept of the Silk Road and subsequent methodological reflections. New laboratory results of scientific analyses of plants, minerals, and human remains in combination with more conventional methods of research contribute to a better understanding of the multidirectionality of exchanges in Pre- and Protohistory. Unsuspected long-distance transfers of items, especially of metals (tin) and biological materials (plants, pathogens, etc.) are discovered. Adding ancient DNA and petroglyphs to the vexed question of the Indo-European migrations across Eurasia complexifies the familiar linguistic, historical, and archaeological research landscape. Recent excavations show the impact of the adoption of artistic elements adapted from the Achaemenid arts, far in the steppe world, and up to China. Multidirectional (including North-South lanes) and multidisciplinary approaches leave space and hope for more rigorous scientific modelizations for the archaeology of Eurasia and the Silk Road.

  • This study explores the concept of postmodernism in literature. There are many ideas which have conflicted with each other, but now postmodernism is real concept. We cannot deny. By researching papers of Jean-François Lyotard, Jean Baudrillard, Jacques Derrida, Michel Foucault, Julia Kristeva, Roland Barthes, Ihab Hassan etc. we find out many characteristics of postmodernism. From that, we propose a conceptual understanding of postmodern literature as follows: Starting from the late 1910s with the poetry of Dadaism (1916), Franz Kafka's prose (Metamorphosis 1915) and drama by Samuel Beckett (Waiting for Godot 1953), postmodern literature coexists with modern literature and is a thriving form from 1960 on. Postmodernism is opposed to modernism in nature in that it accepts nothingness, chaos, games and intertextuality. It tries to solve some difficult problems of modernism making use of science to free people from a life of darkness and dogma. Postmodernism is associated with the information technology revolution, an economic, scientific and technological boom and rapid urbanization.

  • This study intends to explore the content and organization characteristics of elementary school science textbooks in the astronomical domain from the perspective of understanding the astronomical spatial concept. This study analyzed the relevant unit of the achievement criteria in the 2015 revised science curriculum for the 'space' domain in elementary school science textbooks in comparison with that in secondary school textbooks according to the spatial concept analysis criteria by texts, illustrations, and inquiry activities. As a result, elementary school science textbooks were found to be organized around phenomena rather than concepts, targeting observable celestial bodies linked to real life in order to optimize the amount of learning content. However, the learning contents of astronomical observation related to observation and phenomena-centered real life should stimulate the curiosity and imagination of elementary school students and encourage their intellectual participation. Students need to be supported for understanding of the spatial concept to find an answer to the question of 'why'. The content organization for core concepts should be organized around the transferable spatial concept rather than simply focusing on presenting results by accurately describing the phenomena observed by students through scientific practice in order for students to answer various questions that arise in the course of scientific practice.

  • The purpose of this study is to examine the effects of background knowledge on problem solving. To achieve this aim, I proposed the model which shows problem solving process centering around background knowledge, conducted the lessons concerning the concept 'weightlessness' on pre-service elementary teachers, and then classified the pre-service elementary teachers into several groups by the difference of the results presented in the process of solving the problems on weightlessness. And I examined qualitatively the effects of background knowledge on problem solving through the interview with 11 volunteers. On the cause of the failing the problem solving, the failure of acquiring or activating the background knowledge related to the learning concept was most frequently, secondly the use of the background knowledge unrelated to the learning concept, and thirdly the failure of understanding the teaming concept. To acquire or activate the background knowledge related to the teaming concept was more difficult than to understand the new teaming concept, and the cases that use the background knowledge unrelated to the learning concept failed to solve problem. The result of interview, all interviewee understood the learning concept correctly, but all of them who fail to acquire or activate the background knowledge related to the learning concept, or use the background knowledge unrelated to the learning concept, could not solve the problem.

  • This study analyzed the types of scientific humors made by scientifically-gifted elementary school students and their perceptions of making scientific humor. For this, 77 students from $4^{th}$ to $6^{th}$ graders of gifted science education center in Seoul National University of Education were selected. Scientific humors made by the students were analyzed according to the number and types. Their perceptions of making scientific humor were also analyzed through a questionnaire and group interviews. The analysis of the results revealed that most of scientifically-gifted students made more than 2 scientific humors, and the number of scientific humor for each students varied from 0 to 11. The most types they made were the descriptive type and the pun using pronunciation type, but they made various types without any special type to be biased. And They made more the dialogue type than the narrative type, especially the riddle type. They used scientific knowledge that preceded the knowledge of science curriculum in their grade level over two or more years. The scientific knowledge of chemistry was used more than physics, biology, earth science and combination field. The name utilization type was more than the characteristic utilization type and the principle utilization type. Scientific humors in the everyday situation were more than humors in artificial situation. The students had various positive perceptions in making scientific humor such as increase of scientific knowledge, increase of various thinking abilities, deep understanding of science concept and principle, increase of interest and motivation about science and science learning, and increase on sense of humor. They had also some negative perceptions related to difficulties in the process of making scientific humor, lack of fun, and lack of time in the class.

  • Elementary preservice teachers' understanding about the insect molt and metamorphosis was examined. Data were collected through the paper-pencil test of 448 junior students at a National University of Education. The instrument used was developed by Son(2003) and modified for the test. The results are as follows: First, Only 3.1$\%$ of students had a scientific concept on the molt periods in the insect life cycle. Students had an alternative conception that molt occurs either only in the larval period (29.9$\%$) or only in the period from pupa to adult (22.3$\%$). The percentage of the students thinking that molt occurs in the period from larva to pupa was low. Second, 98$\%$ of students stated that molt has to do with the larval growth, but 39.1$\%$ of students had an alternative conception that molt occurs after the larval growth at each instar. 25.1$\%$ had a conception that molt is related with the larval growth, but did not show any further understanding. Third, most students understood the correct meaning of metamorphosis. 34..2$\%$ of students had an alternative conception that metamorphosis occurs only in the period changing from pupa to adult, and only a few thought that it occurs in the period from larva to pupa. 24.8$\%$ of students had a scientific concept on the periods in which metamorphosis occurs. Fourth, some students understood the hatching process as molt in the sense that the egg shell is taken off (21.0$\%$), and as metamorphosis in terms of the appearance change from egg to larva (25.0$\%$). Fifth, 35.5$\%$ of students selected bees as an insect of incomplete metamorphosis, and 35.3$\%$ responded 'I have no idea', showing that they had poor understanding about the insect life cycle.

  • The purpose of this study is to investigate the effectiveness of academic achievements, science process skill and scientific attitude. The subjects of this study were 68 fourth-grade elementary school students who were 33 students for the 5E learning cycle instruction and 35 students for traditional instruction. The control group was taught with traditional teaching method, while the experimental group was taught 'the change to the volume of material due to heat' unit of 4th grade with the developed learning cycle model. The results were as fellows: First, the learning cycle instruction is more effective for understanding of a concept related to the change to the volume of material due to heat. Second, the learning cycle model seems more effective for the expansion of both scientific inquiry ability and scientific attitude.

  • Science, Mathematics, Engineering, and Technology (STEM) integrated education has been spotlighted as a new approach for promoting students' conceptual understanding and supporting their future career in STEM field. There is increasing evidence of the positive impact of using a whole design process that can be an example of STEM integrated activities to improve students' conceptual understanding and problem solving skills. However, there is a lack of information on how teachers should accomplish science and engineering integration activities in their classroom and what process they should pay attention. To answer this question, we research the relationship between an design process and students' conceptual understanding using an engineering design activity, called 'Save the Penguins', and study on how each step in an engineering design process in this activity enhance students' conceptual knowledge in science. We found that testing their prototypes and discussing with their peers were the most important process for students to understand and apply science concept for their design, even though the whole engineering design process (demonstration about radiation, discussion about examples in our lives, and testing and reviewing their prototypes, and making final design) helps the students understand the scientific concepts.
