  • The purpose of this study is to compare by learner groups(K-12, geology-related majoring students, science teachers) how geologic fieldwork education cases in domestic and foreign papers for recent 20 years reflect the elements of inquiry in field geology. The total number of analyzed cases is 53(58 for double counting), and the analysis was conducted on the elements of inquiry in field geology and their sub-element. As a result, there was a clear difference between the cases of geologic fieldwork education for K-12 and college students majoring in geology-related disciplines, in the way of reflecting elements of inquiry in field geology. Because most of K-12 target fieldworks were designed based on the curriculum, it mainly included 2-3 elements of observations, representations, and/or abductive reasoning. On the other hand, because fieldworks for geology-related major students aim to train geologic experts, it diversely contained four or five of the elements of inquiry in field geology, including spatial thinking and diachronic thinking in a high proportion, and also frequently used activities that require specialized skills such as geological mapping. Fieldworks for science teachers were found to have mixed features of K-12 and geology-related major students. Considering the diversity of included inquiry elements, similarities with the activities performed by geologists, and the autonomy of learners, it was analyzed that geologic fieldwork for geology-related major students was more close to authentic geologic inquiry than fieldwork for others. Based on the results of this study, we suggested implications for improving geological fieldwork as authentic science inquiry.

  • Mathematics education starts from learning the concept of number. How the children at the beginning of school age learn the concept of natural number is therefore important for their future mathematics education. Since ancient Greek period, the concept of natural number has reflected various mathematical-philosophical points of view at each period and has been discussed ceaselessly. The concept of natural number is hard to define. Since 19th century, it has also been widely discussed in psychology and education on how to teach the concept of natural number to the children at the beginning of school age. Most of the works, however, were focused on limited aspects of natural number concept. This study aims to show the best way to teach the children at the beginning of school age the various aspects of natural number concept based on activistic perspective, which played a crucial role in modern mathematics education. With this purpose, I investigated the theory of the activistic construction of knowledge and the construction of natural number concept through activity, and activistic approaches about instruction in natural number concept made by Kant, Dewey, Piaget, Davydov and Freudenthal. In addition, I also discussed various aspects of natural number concept in historical and mathematical-philosophical points of view. Based on this investigation, I tried to find out existing problems in instructing natural number to primary school children in the 7th National Curriculum and aimed to provide a new solution to improve present problems based on activistic approaches. And based on activistic perspective, I conducted an experiment using Cuisenaire colour rods and showed that even the children at the beginning of school age can acquire the various aspects of natural number concept efficiently. To sum up, in this thesis, I analyzed epistemological background on activistic construction of natural number concept and presented activistic approach method to teach various aspects of natural number concept to the children at the beginning of school age based on activism.

  • The purpose of this paper is to identify woodblocks which were engraved in the providences in the mid Chosun dynasty, especially ones engraved under the auspices of Yu Heui-chun(柳希春), but not listed in $\boxDr$Kosachwalyo 攷事撮要$\boxUl$. This could be done by the analyzing $\boxDr$The Diary of Miam 眉巖日記$\boxUl$ written by Yu Heui-chun. It is a book which recorded daily life of eminent scholar and official covering political, social and cultural aspects, books and family matters. There were two categories of books published under the auspices of Yu Heui-chun. One is the books written by his grandfather in law, Choi Bu(崔溥), which were $\boxDr$Keumnamjip 錦南集$\boxUl$ collective works of Choi Bu, and $\boxDr$Pyohaerog 漂海錄$\boxUl$, essays on travelling across China. The other is the books for children, $\boxDr$Sinjeung Yuhap 新增類合$\boxUl$ for teaching characters and $\boxDr$Sog Mong-gu 續蒙求$\boxUl$ for moral education. These woodblocks have to enlisted in the woodblock catalogs. The analysis shows that most of these woodblocks by Yu Heui-chun were not recorded in either of two $\boxDr$Kosachwalyo 攷事撮要$\boxUl$ editions published in 1575 and 1585. In this respect, $\boxDr$The Diary of Miam$\boxUl$ proved itself to be of great significance in terms of bibliography studies.

  • Since information scientists have begun trying to quantify significant research trends in scientific publications, '-metrics' research such as 'bibliometrics', 'scientometrics', 'informetrics', 'webometrics', and 'citation analysis' have been identified as crucial areas of information science. To illustrate the dynamic research activities in these areas, this study investigated the major contributors of '-metrics' research for the last decade at three levels: nations, institutions, and documents. '-metrics' literature of this study was obtained from the Science Citation Index for the years 2001-2011. In this analysis, we used Pathfinder network, PNNC algorithm, PageRank and several indicators based on h-index. In terms of international collaborations, USA and England were identified as major countries. At the institutional level, Katholieke University, Leuven and the University of Amsterdam in Europe and Indiana University and the Office of Naval Research in the USA have led co-research projects in informetrics areas. At the document level, Hirsch's h-index paper and Ingwersen's web impact factor paper were identified as the most influential work by two methods: PageRank and single paper h-index.

  • This study was carried out to examine whether children had the naive psychological knowledge that the mental states ate requited to understand the intentional actions, whether their psychological knowledge was organized as a theory, and in what aspects the knowledge changed as children get older. Three- to 11-year-olds were presented with two types of tasks. In action explanation tasks, children were presented with simple descriptions of two characters engaging in specific actions and then asked to explain the characters' action. In action prediction tasks, they were told stories depicting a character's desire and belief and then asked to predict the action of the character. Three-year-olds explained the action in terms of abstract construct such as emotion, intention, and desire, and they predicted the character's action on the basis of her/his desire and explicit belief but not on the basis of inferred false belief and traits. In addition when they were asked to explain one mental state, they explained in terms of other mental states, suggesting the coherence of their knowledge. The present results suggested that even 3-year-olds' psychological knowledge was organized as a theory, in that it was used as a causal device in explaining and predicting human actions, and it had abstractness and coherence. Older children's knowledge was different from 3-year-olds' in that older children explained the action in terms of more complicated mental states such as beliefs and traits. The nature of the developmental change in psychological knowledge was discussed.

  • The economy of the EU left behind the US economy in many aspects and the gap is widening. One major reason that promoted the EU's leading position, is the ability to continuously advancing industrial technology and it's high level of competitiveness. The role as a powerhouse of technological development is nurtured by a systematic attempt of the EU commission to stimulate international cooperation. Although the EU is focussing its efforts on international cooperation between EU-member states, nonmembers, namely Korea, can profit from this policy as well and generate win-win situations for both cooperating partners. Despite the enormous benefits for the Korean economy that would result from close ties with the EU in terms of technological cooperation, academic research in this area is very sparse. The main focus of the Korean academic community has been on the US and Japan so far; the cooperation between Korea and the EU was rather ignored. The purpose of this paper is to shed light on the potential of technological cooperation between Korea and the EU. After an introduction, chapter 2 explains the technology and innovation policy of the EU. Chapter 3 introduces the Framework Program for Research and Technological Development of the EU. Chapter 4 focuses on small and middle sized businesses and examines EUREKA, the EU’s effort to coordinate pan-european research cooperation.

  • Microarray is a new technique for gene expression experiment, which has gained biologist's attention for recent years. This technology enables us to obtain hundreds and thousands of expression of gene or genotype at once using microarray Since it requires manual work to analyze patterns of gene expression, we want to develop an effective and automated tools to analyze microarray image. However it is difficult to analyze DNA chip images automatically due to several problems such as the variation of spot position, the irregularity of spot shape and size, and sample contamination. Especially, one of the most difficult problems in microarray analysis is the block and spot addressing, which is performed by manual or semi automated work in all the commercial tools. In this paper we propose a new algorithm to address the position of spot and block using a new concept of regular structure grid searching. In our algorithm, first we construct maximal I-regular sequences from the set of input points. Secondly we calculate the rotational angle and unit distance. Finally, we construct I-regularity graph by allowing pseudo points and then we compute the spot/block address using this graph. Experiment results showed that our algorithm is highly robust and reliable. Supplement information is available on http://jade.cs.pusan.ac.kr/~autogrid.

  • Modern geography in France since the end of 19th century was begun with regional geography. France after losing the Franco-Prussian war in 1871 had tried to regain the deteriorated national proudness through the colonial expansion. The social and historical contexts in France had encouraged French geographers to engage in detailed small area studies. In particular, after Blache became a faculty at Sorbonne University his idea on integrative rather than selective description on area studies had gained paradigmatic popularity not only in geography but in other disciplines. The regional geography tradition was then firmly established as a science and as an art by Vidalian school until the beginning of Second World War. However, when industrialization and urbanization were the dominant science since the 1950s spatial analytic geography has become popular research tradition replacing the previledged regional geography. Nevertheless, geography in France is still acknowledged as an interesting and valuable discipline since regional geography tradition had accumulated rich knowledges on various regions. As regional geography provides valuable information and helps to understand various world regions, it should be regenerated as a research tradition which are able to fulfill societal needs accruing nowadays. By doing this, geography can rectify its disciplinary identity which has been disintegrated internally by giving too much emphasis on specialties, and melding into nearby disciplines. Our geography education for the chorography in particular focuses mainly on the listings of simple geographic facts, in this regard. Rather than attracting students' concern and motivation, geography is considered as a subject oriented toward simply memorizing geographic facts. To overcome these problems, regional geography should be discussed openly and popularized in research. Regional geographic methods available and results produced in other countries should be introduced, and critical assessments should be made for selective acknowledgment for nurturing our regional geography.

  • This researcher looked at the characteristics of "$N\bar{a}tya$ $\acute{s}\bar{a}stra$" acting techniques focused on body expressions and sought to utilize it as training method for modern actors. 'Body postponement as a symbol' is a key characteristic of "$N\bar{a}tya$ $\acute{s}\bar{a}stra$" acting techniques, and each facial expression, gesture, and movement performed by an actor has a specific meaning. Therefore, the study on "$N\bar{a}tya$ $\acute{s}\bar{a}stra$" has been treated as a major study mainly in the non-realistic expression style or the body-centered acting theory. Therefore, a study on "$N\bar{a}tya$ $\acute{s}\bar{a}stra$" acting techniques was mainly dealt with as a major research subject in the nonrealistic expression style or body-centered acting theory. This study, on the other hand, emphasized the importance of research on the utilization plan of actor training, which can be usually used in realistic plays as well as non-realistic plays. According to psychologists such as Damasio and Eckman, internal impulses can also be triggered through expressions and actions associated with emotions. In addition, not only acting through the actor's inner impulse, but also expression of the actor's faithful external emotion can trigger the emotion of the audience. Such a case can be a psychological basis that "$N\bar{a}tya$ $\acute{s}\bar{a}stra$" acting techniques, which defines rasa and expresses it physically, can be used as a methodology to enhance inner truth. Therefore, the study on the actor training utilizing ing "$N\bar{a}tya$ $\acute{s}\bar{a}stra$" can be applied as an effective approach in the study of contemporary acting theory which intends to integrate inner impulse and external expression.

  • The narratives of the digital age have attempted interactions, and the interactive storytelling represented by the Branch Narratives has a problem of the expensive production cost of many optional implementations and poor narrative compared to linear story. As an alternative to this, this study proposes a user-oriented storytelling using user's personality traits. Using the Enneagram, a model of human psyche, and the Actantial model of the semiotician Greimas, when stories and characters are the same, the story could be reconstructed by deriving different topics from the same story according to the user's Enneagram personality type. The theme is determined by defining the axis of the desire of the Actantial model by respectively setting the character with the user's Enneagram type as the subject and the core value in the type as the object. The axis of Power could be defined by the stress and security points in Enneagram. In this way, we can derive the themes of 9 Enneagram types and the corresponding Actantial model and make plots. The users will appreciate one of these reconstructed plots in different perspectives and themes, depending on their personality type. In this study, we applied the above methodology to the story of the pansori novel "Tokkijeon". User-centered storytelling is a new attempt to predict user's choice and reconstruct the story based on the user's personality and perspective.
