최근 디지털 컨텐츠의 기하급수적인 증가와 함께 사용자가 접하고 관리해야 하는 파일의 양이 급격히 늘어나고 있으며 이에 따라 폴더의 계층구조가 넓고 깊어지는 현상이 나타나고 있다. 현재 파일시스템은 크게 두 가지 형태로 나누어 볼 수 있는데, 사용자 자신에게 의미 있는(semantic) 계층구조(hierarchical structure)형태의 폴더 내에 파일을 저장하는 방식과 Meta Tag를 사용한 방식이다. 이러한 두 가지 파일시스템을 사용자가 인식하고 Conceptual Model을 형성해 가는 과정에 있어서 사용자의 지리적, 역사적 전통 등의 문화적 요소들이 기저에서 작용하게 된다. 본 연구에서는 각기 다른 문화적 성향을 가지고 있는 사용자 간의 File System을 인식하고 구조화하는데 있어서 차이점이 있을 것이라는 가설을 수립 하였고, 가설을 검증하기 위하여 파일 시스템의 사용 행태를 분류하고, 이러한 행태들이 사용자의 문화적 요소에 따라 어떠한 차이를 보이는지에 대하여 페이퍼 프로토타이핑 등의 기법을 사용하여 실험을 설계 하였다. 또한 이러한 연구모델의 검증을 위하여 파일럿 테스트를 진행하여 실효성 있는 가설검증방법에 대한 모델을 제안하고자 한다.

This study discusses on the historico-genetic instruction on fraction. The textbooks of the current curriculum include the variety of contexts of fraction to be intended to connect with the conception of ratio in the grade 6. However mary elementary students have understanding limited to whole-part relation only. This study propose a method on the basis of the process of measurement by an absolute unit. The idea is related to The genesis of fraction in Egypt.

This thesis is a result of a study of the treatment course of post traumatic stress disorder because of the historical incident which is described in the novel, Uncle Suni by Hyun Ki-young. Uncle Suni survived the massacre which happened during the 4.3 Incident in Jeju Island. However, living a buried life, she suffers a historical trauma. To cure her disorder, she had to know the cause of her illness, such as auditory hallucination, mysophobia, etc. The author describes that kinds of patients should be ensured to get help not only in duty of the society but of the country and that historical justice should stand right. Uncle Suni reexperienced the incident when she happened to discover 'the white bones' and 'the lead bullets' while she was working in her 'Ohmpang field'. To cure her illness, she needed to confess her guilt that she had escaped from the massacre, and deep appreciation about the incident, which means she had to testify, and in the course of the testimony, she had to confess her inner feelings. To solve the historical trauma, there should be a recovery of connection between the patient and the society. The course of treatment should go from the patient herself to the realm of the society through which the patient, Uncle Suni can reach the recovery.

In Korea, the traces of Mongolian history and culture are often found in Korean life and customs. Under these perceptions, this study has attempted to develop the learning contents using the Mongolian historical and cultural heritages in Korea. For this, the perspective on Mongolia in Korean History and Social Studies textbooks and the exhibition of Mongolian cultural materials in a museum have been analyzed. In addition, this study has researched a plan to develop learning contents for exhibition and education using the Mongolian historical & cultural heritage and folklore materials in Korea and people's perspective on Mongolia in the ancient western maps as a way of understanding the historical and cultural heritage between Korea and Mongolia. In addition, a way of taking advantage of the Mongolian historical and cultural heritage in Korea from the view of world history has been proposed to share historical views and promote cultural exchanges between the two countries. Furthermore, the development of learning contents of the museum using the historical and cultural heritage between Korea and Mongolia could be grounds for humanistic studies from the view of understanding multiculture and characteristics of international culture.

Late-Koryeo people networks were constructed from four different history books that were written by various historic aspects in the period from king Kongmin to the final king of the Koryeo, Kongyang. All networks constructed in this study show scale free network properties as if most social networks do. Tajo-sillok preface is one of subjectively written history book that described personal history of the Lee Seong-gye and his ancestors. It is confirmed that the book is one of the most biased-written history books through network study. Jeong Do-jeon known as a Chosun dynasty projector is not greatly contributed for founding of a Chosun dynasty in network study and various historical documents as well. In this network study, we provide objective historical information in the historical situations of the late-Koryeo and during establishment procedure of Chosun dynasty. Hub nodes in network is denoted highly linked nodes, called degree. Stress centrality is a unit to measure positional importancy in the network. If we employ two factors, degree and stress centrality to determine hub node, it represents high connectivity and importancy as well. As comparing values of the degree and stress centrality, we elucidate more objective historical facts from late-Koryeo situations in this study. If we further develop and employ a new algorithm that is considered both degree and stress centrality, it is a very useful tool for determining hub node.

This is a literature study about the concept of 'Division into Equal Parts' in middle school geometry. First, we notice that the concept of the division into equal parts in middle school geometry is given in four themes, which are those of line segments, angles, arches and areas. Second, we investigate and analyse the historical backgrounds of these four kinds of divisions into equal parts. Third, the possibility of extension in terms of method and concept was researched. Through the result of this study, we suggest that it is desirable to use effective utility of history in mathematical teaching and learning in middle school.

We develop the Spatio-Temporal Graph to imbue the historical context to the situations in a virtual world, and an ontology to enable a structural description of their elements such as the objects, relationships, and activities. In the time dimension the graph models all the temporal phases of the future besides the past and present in a comprehensive manner, and all the spatial aspects in an intuitive but efficient fashion. The overall architecture composing the Physical Layer, Logical Layer and Conceptual Layer which are integrated according to their interrelations allows events occurring in their corresponding worlds to be simulated in historical context. The S-T Graph could be used both to simulate the situations in the virtual world and to realize the knowledge systems of the virtual inhabitants to be used in judging and evaluating those situations. By adding temporal changes to the multi-layered architecture of our virtual world, this model lays a foundation for maximizing the diversity of situations in the simulation of a virtual world.

This study was designed to suggest a landscape agreement in order to effectively preserve historical and cultural landscapes at this point of time when many landscape agreements are being concluded for landscape management, to analyze landscape management methods according to the problems of comprehensive and widespread landscape agreements and landscape types and to generalize landscape agreement contents. To begin, sustainable and practical landscape management plans that local people can themselves participate and carry out were proposed, based on historical and cultural landscape preservation guidelines extracted from the consideration of domestic and foreign cases about landscape management by citizen autonomy and participation. The guidelines considered what regional residents would follow by themselves, as well as what should be considered with regard to the accessibility and symbolism of a building's appearance and external spaces designed with the motif of historical and cultural landscapes. The guidelines also pay attention to the maintenance management of outdoor advertisements and facilities in order to maintain a pedestrian-friendly street environment which pursues designs in harmony with the existing historical and cultural landscapes. In addition, the recommended guidelines that are considered less important,are restricting the sizes of buildings, encouraging maintenance management of the details and external spaces to hide building facilities and block them from being exposed and including information about the use of nature-friendly materials, and the management of neon signs in the landscapes and lighting time during the night. These results demonstrate that local residents need to improve the landscapes and change their consciousness by themselves to maintain the historical and cultural landscapes with a sense of tradition.

역사적으로 알콜은 인류에게 식품으로써 뿐만 아니라 근래에는 미래의 무공해 대체 에너지로써 많은 기대를 모으고 있다. 식품의 용도로써는 단연 주류를 꼽게 되는데 이 목적으로는 알콜의 발효수율을 올리는 것만이 아니라 소비자의 기호에 맞는 향과 맛등이 중요한 인자로 작용하게 되어 균주 조작에 한계가 있다고 보겠다. 반면 대체 에너지로써의 알콜은 가능한 수단 방법을 다 동원해서 값싸게, 수율높게만 개선하면 되기 때문에 최근 인구에 회자되고 있는 각종 생명공학기법이 광범위하게 사용될 수 있다고 본다. 목적에 따라서 원료는 물론 발효균주도 다양하게 사용되어 지는데 다음에서 용도별로 대표적인 예를 살펴보겠다.
