Due to the trend toward computerization of business services in public sector and the push for e-government, the volume of records that are produced in electronic system and the types of records vary as well. Of those types, dataset is attracting everyone's attention because it is rapidly being supplied. Even though the administrative information system stipulated as an electronic record production system is increasing in number, as it is in blind spot for records management, the system can be superannuated or the records can be lost in case new system is developed. In addition, the system was designed not considering records management, it is managed in an unsatisfactory state because of not meeting the features and quality requirements as records management system. In the advanced countries, they recognized the importance of dataset and then managed the archives for dataset and carried out the project on management systems and a preservation formats for keeping data. Korea also is carrying out the researches on an dataset and individual administrative information systems, but the official scheme has not been established yet. In this study the items for managing archives which should be reflected when the administrative information system is designed was offered in two respects - an identification method and a quality requirement. The major directions for this system are as follows. First, as the dataset is a kind of an electronic record, it is necessary to reflect this factor from the design step prior to production. Second, the system should be established integrating the strategy for records management to the information strategy for the whole organization. In this study, based on such two directions the strategies to establish the identification for dataset in a frame to push e-government were suggested. The problem on the archiving steps including preservation format and the management procedures in dataset archive does not included in the research contents. In line with this, more researches on those contents as well as a variety of researches on dataset are expected to be more actively conducted.

3D Geo-spatial information models have been widely used in the field of Civil Engineering, Medical, Computer Graphics, Urban Management and many other. Especially, in surveying and geo-spatial field, the demand for high quality 3D geospatial information and indoor spatial information is so highly increasing. However, it is so difficult to provide a low-cost and high efficiency service to the field which demand the highest quality of 3D model, because pre-constructed spatial data are composed of different formats and storage structures according to the application purpose of each institutes. In fact, the techniques to construct a high applicable 3D geo-spatial model is very expensive to collect and analyze geo-spatial data, but most demanders of 3D geo-spatial model never want to pay the high-cost to that. This study, therefore, suggest the effective way to construct 3D geo-spatial model with low-cost of construction. In general, the effective way to reduce the cost of constructing 3D geo-spatial model as presented in previous studies is to combine the raw data obtained from point cloud observatory and UAV imagery, however this method has some limitation of usage from difficulties to approve the use of raw data because of those have been managed separately by various institutes. To solve this problem, we developed the linking & management system for unifying a high-Resolution raw geo-spatial data based on the point cloud DB and apply this system to extract the basic database from 3D geo-spatial mode for the road database registration. As a result of this study, it can be provided six contents of main entries for road registration by applying the developed system based on the point cloud DB.

The purpose of this study is to examine the archetype of the Gyeongju Castle walls and the facilities around it to bring together previous studies and identify the specific scale and structure of the archetype. The findings can be summarized as follows. First, we verified the exact location and dimensions of the castle through an over-lay of land registration maps from the Japanese colonial period, land registration maps from the present day, cadastral maps, and excavation records. Second, the dimension of the rampart and fort of the castle were discovered by combining and analyzing historical evidence, modern research data, historical site studies from the Japanese colonial era, and maintenance records. Third, the historical records related to the yeojang (rampart sub-wall) formats in the Joseon Dynasty were used to examine the archetype of the yeojang. This study led to the discovery of the archetype of the Gyeongju castle yeojang in the early stage of King Munjong's reign (1451), and the archetype created after the Japanese Invasion (16th century). And finally, although most of the rampart is not present, the structure of the castle can be estimated based on historical research, and research materials modern and contemporary(excavation conservation field survey). In addition, this study presented a archetype restoration plan for each site, to be used as foundational data for future restoration projects.

Standards-curriculum based archival contents for education is the best effective teaching and learning units for historical thinking abilities. This paper purposes a developing procedures of an archival contents for education that is theoretical instructions of developing an archival contents for education by the National Archives of Korea. This paper can be used of the theoretical bases for the National Archives of Korea by proposing the methodology of development of an archival contents for education. The developing procedures of an archival contents for education is the same with the procedures of developing an e-learning contents that has planning, analyzing, designing, developing and assessing steps but it is characterized by an archival contents for education that is curriculum standards analysis, collection analysis, and detailed design for structured formats in effective-accomplishments for teaching-learning objectives. I propose the procedures for determining teaching-learning subjects that enable the development of an archival contents for education by curriculum standards analysis. I also propose the procedures for deriving the key words from the teaching-learning subjects. Collection analysis methods analyze key records that correspond to the learning subjects according to the selection criteria of primary sources. In the steps of designing, titles of contents and contents structures have to be determined and storyboards based on flowchart of learning have to be made of according to the results of analyses. In the steps of developing contents, making a copy of primary sources like a original is the key points. And also in the steps of assessment, products of teaching-learning contents to effectively achieve the teaching-learning objectives have to be estimated by the appraisal board. Finally I propose that user's survey research after the services have to be reflected on contents updates and new developments of contents.

Archival contents service for education is now a major service program in a foreign National Archives. Therefore We need to study their archival contents services in more depth-analysis methods for the development of our contents. My study is based on the summary of the Homepage Sites for Education of the TNA of UK and the NARA of USA. And also a depth-case study on structures of the samples, 'Coldwar' contents of the TNA and the 'McCarthy' contents of the NARA. As a results, first, the formats of archival contents for teaching-learning materials should be in consistent contents structures like a standard textbooks. Second, archival contents service for teaching-learning materials certainly have to support original images of primary resources and educational kits in order to read easily primary sources. Third, given the costs of development, it's desirable for archive to develop archival contents for teaching-learning materials in the way of cross-use by age and curriculum. Forth, when selecting primary sources for teaching-learning materials, priorities have to be given to the text-sources in the light of learning purposes for history education. Fifth, National archives must develop archival contents for teaching-learning materials in connection with standard curriculums in order to promote a nation-wide use.

In the midst of the aging of underground facilities in urban areas and anxiety about road excavation safety accidents, the Ministry of Land, Infrastructure and Transport began to build Underground Geospatial Infomation Map from 2015 as part of the 「ground subsidence prevention measures」 and efficient use of underground spaces. So, the scope is spreading every year. The current Underground Geospatial Infomation Map information is web-based and is operated in a desktop environment, so it is true that there are some limitations in its use in a field environment such as an excavation construction site. The Underground Geospatial Infomation Map, built and operated in a web-based environment, is a large-scale 3D data. Therefore, in order to service by transmitting data to the field without delay, it is necessary to lighten the Underground Geospatial Infomation Map data. In addition, the current Underground Geospatial Infomation Map is not unified in data formats such as 3DS and COLLADA, and the coordinate system method is also different in relative coordinates and absolute coordinates. In this study, by analyzing domestic and overseas prior research and technical use cases, a mobile Underground Geospatial Infomation Map data format and a lightweight method were presented, and a technology development was conducted to create a mobile underground space integration map in the presented format. In addition, the weight reduction rate was tested by applying 3D data compression technology so that data can be transmitted quickly in the field, and technology was developed that can be used by decompressing 3D data compressed in the field. finally, it aims to supplement the technology experimentally developed in this study and conduct additional research to produce it as software that can be used in the excavation site and use it.

Houshan's Comments on Poets and Poetry by Chen Shidao, one of the most famous comments on poets and poetry in the Northern Song Dynasty, is regarded as the early masterpiece of the literary critic genre called comments on poets an poetry. In particular, the theory on poetry of Houshan's Comments on Poets and Poetry reflected the overall literature fashion of the Song Dynasty, and captured the typical arguments of poetics in the Song Dynasty. The poet's character-building and accumulation of knowledge, the study of Du Fu and other poets and a quest for "No Trace" reveal the practice and aesthetics of the poets in the Northern Song Dynasty. So far, Chen Shidao has been known as a formalist poet, and he has actually focused on learning the rules of verse and learning classical poetry. But the final goal of his theory on poetry was a free creation, not the strict rules. He just thought that he could get the freedom of creation by constantly learning rules and building a poem. Therefore, his comments in Houshan's Comments on Poets and Poetry can not be regarded as simply formalist views. Because he wanted to achieve his ideal freedom of creation with elaborate formats and content.

This study analyzed the usage characteristics and requirements of students who are users of the middle school education space, and the following results were obtained: First, we could see that various types of classes were needed, such as lecture-style classes, team projects, and four-person consultation and discussion classes, in a way that helped to improve the desirable teaching patterns and learning ability. Second, the place where space was used during the break and the relationship between peers, revealed that most of them were in the classroom and the hallway, and the peer group was composed of three to eight people or more, that were active with various compositions. Third, a gym, library, toilet, stairway, cafeteria, nurse's office, and teachers' room appeared in the center of the building, indicating the need for a balanced layout. Fourth, physical education (dance) rooms, audiovisual rooms (performance rooms), workshops (personal creation), snack bar, rest area, spacious indoor square, and study rooms were needed as facilities that can help learning activities other than current facilities. These outcomes show that the existing classroom layout and space composition formats require some spatial restructuring.

Visual information is widely used to deliver health information more effectively on social media, but there is lack of research on how effectively visual information delivers health information on social media. This study reports Facebook users' reading patterns and cognitive tests (recall and recognition tests) results using health-related Facebook posts. For this study, 21 college students participated in online questionnaire, eye tracking experiment, and recall and recognition tests. First, users paid their attention to the area that contains information (i.e., users focused on the main text rather than photos that do not contain information). Second, in the case of Facebook posts containing infographics, users paid their attention on the infographics, but the recall and recognition test results of the posts with infographics were lower than the posts containing photos. Particularly, when the infographics are in a complex collage format, recall and recognition tests result lower scores. Third, regarding the length of the text, the Facebook posts with short text resulted in higher recall and recognition test scores than the posts with medium or long texts. This study suggested to Facebook health information providers and distributors how to design Facebook posts for delivering health information more effectively.

With the increased development of 3D VR applications augmented by recent VR/AR/MR technologies and by the advance of 3D devices, interchangeability and portability of 3D data have become essential. 3D files should be processed in a standard data format for common usage between applications. Providing standardized libraries and data structures along with the standard file format means that a more efficient system organization is possible and unnecessary processing due to the usage of different file formats and data structures depending on the applications can be omitted. In order to provide the function of using a common data file and data structure, this research is intended to provide a programming binding tool for generating and storing standardized data so that various services can be developed by accessing the common 3D files. To achieve this, this paper defines a common data structure including classes and functions to access X3D files with a standardized scheme using the Python programming language. It describes the implementation of a Python language binding viewer, which is an X3D VR viewer for rendering standard X3D data files based on the language binding interface. The VR viewer includes Python based 3D scene libraries and a data structure for creation, modification, exchange, and transfer of X3D objects. In addition, the viewer displays X3D objects and processes events using the libraries and data structure.
