This paper is to verify the effectiveness of 'Hybrid Disaster Management Strategy' that integrates 'RTM(Real-time Monitoring) based On-line' and 'UAV based Off-line' system. For landslide prone area where sensors were installed, the conventional way of risk management so far has entirely relied on RTM data collected from the field through the instrumentation devices. But it's not enough due to the limitation of'Pin-point sensor'which tend to provide with only the localized information where sensors have stayed fixed. It lacks, therefore, the whole picture to be grasped. In this paper, utilizing 'Digital Photogrammetry Software Pix4D', the possibility of inference for the deformation of ungauged area has been reviewed. For this purpose, actual measurement data from RTM were compared with the estimated value from 3D point cloud outcome by UAV, and the consequent results has shown very accurate in terms of RMSE.

We introduce the application that automatically makes several images stored in user's device into one video by using the different climax patterns appearing for each film genre. For the classification of the genre characteristics of movies, a climax pattern model style was created by analyzing the genre of domestic movie drama, action, horror and foreign movie drama, action, and horror. The climax pattern was characterized by the change in shot size, the length of the shot, and the frequency of insert use in a specific scene part of the movie, and the result was visualized. The model visualized by genre developed as a template using Firebase DB. Images stored in the user's device were selected and matched with the climax pattern model developed as a template for each genre. Although it is a short video, it is a feature of the proposed application that it can create an emotional story video that reflects the characteristics of the genre. Recently, platform operators such as YouTube and Naver are upgrading applications that automatically generate video using a picture or video taken by the user directly with a smartphone. However, applications that have genre characteristics like movies or include video-generation technology to show stories are still insufficient. It is predicted that the proposed automatic video editing has the potential to develop into a video editing application capable of transmitting emotions.

Located in Namwon-si, Jeonlla Bukdo, Gwanghallu Garden is created around Gwanghallu, which was a government office in the period of Joseon Dynasty and shows its looks as a government office building of the times. However, Gwanghallu Garden is recognized rather as a background site of Chunhyangjeon, representing a local culture, than the features and picture as a government office garden in the period of Joseon Dynasty because Gwanghallu appeared as the background of Chunhyangjeon in its Chinese character script and, after 1930s, Chunhyang Sadang was built up and Chunhyang Festival held, and it's recognized rather as a site for arousing national consciousness and cherishing Chunhyang for its integrity in the Japanese ruling era of Korea than as a government office building in the period of Joseon Dynasty. With it being more recognized as the background of Chunhyangjeon than an ancient government office building, Gwanghallu has been managed as a private house garden or event place of folk festival as the background of Chunhyangjeon than preserved and managed as ancient government office building, and now the looks and features as a garden of government office are hardly seen because of indiscriminate trees and making of structure and spaces. Therefore, to preserve and maintain Gwanghallu Garden as the garden of government office in the period of Joseon Dynasty, it's required to survey the trees, structure and spaces created in Gwanghallu Garden and compare the true condition with its original looks by studying its literature and it's suggested that the garden area created around Gwanghallu should be repaired and managed by separation from as the background of Chunhyangjeon. Such means of management may keep the looks of Gwanghallu as the ancient office garden while Chunhyangjeon can also settle down as a local culture in the background.

This research was carried out to investigate the history and development process of the Bansu(泮水) which appeared uniquely at the Chinese 'temple-school(廟學)', Confucian schools as the common and necessary facility through the literature reviews and field surveys. The earliest record about the Bansu was shown in "The Book of Odes(詩經)". Originally Bansu was the water system which flowed near the 'Banpalace(泮宮)', but, in the following time, Bansu has become the symbol of the school which was built by the feudal lords and a very important element in the temple-school landscape. Temple-schools were started at Song(宋) Dynasty and at that time there was no certain form of Bansu, just the natural water course near the structure. Until Ming Dynasty, the "Picture of the Feudal lords' Ban-su" in the book "Samjedohoe(三才圖會)" that compiled by Wang-Xi(王圻), the form of Bansu was appeared to be transformed as the half-round pond. And the half-round pond as called Banji(泮池) of today's form was all rebuilt after Ming Dynasty. The half-moon pond appeared at the private houses, shrines, temples and villages were influenced by the book. From this research we can get the conclusions that Banji seemed one of the sacred one and used in the space arrangement formally for the various functions. This research has found the cultures of half-moon ponds which were used uniquely in China.

The purpose of this study was to develop picture testing instrument for measuring children's causal reasoning ability on events that can occur in daily life. The measurement instrument contains three domain of human development; haman behavior domain, human psychology domain, and natural/physical domain. Through this study, researchers designed a concept model based on theoretical framework and prior studies and investigated the reliability and validity of the measurement instrument which was developed in accordance with the concept model. For the empirical validation research, a pretest was conducted to 336 elementary school students in grade 2 to 4 in Seoul. Considering reliability and validity of the developed measurement instrument and factor loadings, researchers sorted out 18 questions. And then 18 question test and KICE Critical Thinking Ability Test was conducted to 509 elementary school students in grade 1 to 4 in Seoul. According to the result of the tests, the researchers sorted out final 12 questions. The Cronbach's alpha, reliability of the children's causal reasoning ability test consisted of the final 12 question, was significant as .72. Also, the result of exploratory factor analysis showed that factors of this test were haman behavior domain, human psychology domain, and natural/physical domain. Moreover, the correlation between the KEDI Reasoning Ability Test(2003) scores and the scores of the test developed in the current study was significant as .55. Finally, the result of the analysis about children's grade differences, the development by discrepancy of age was significant in total points and that of each domain. The children's causal reasoning ability test developed by this study can be useful not only for the evaluation of children's thinking ability but also for screening of the handicapped children in thinking ability development.

"Seonweon Bogam" was made for the purpose of delivering information on the tomb of members of the royal family of the Joseon Dynasty. Accordingly, it covered all of Sando making a pictorial expression of the tomb. But its value has been doubted as it is roughly expressed and different from the picture of the actual scene. But "Seonweon Bogam" is the only book that covers Sando of all the kings of the Joseon Dynasty but contains the elements making it possible to estimate the possibility that the original Sando might be used in making Sando. Accordingly, it is a high time to make an in-deep study of this. This study attempted to investigate Sando included in "Seonweon Bogam" with a focus on the expressive style. For this purpose, it sought to analyze seven elements such as the exposure, the legend, locational information, direction, waterway and road, expression on water and Fengshui(風水) terminology. As a result, the following conclusion was drawn: Sando concerning the tombs of members of the Joseon Dynasty was continually made. It was made in two ways such as the way of drawing the scene on spot and the way of imitating the existing made material. And it could be estimated that there is a possibility that Sando of "Seonweon Bogam" might be copied by the figure with only a little expertise about Sando but on the basis of several materials about the existing Sando of the royal family.

Gwon Geuk-jung wrote Juyeokchamdonggyejuhae(hereinafter Juhae) and established his Internal Alchemy(Nae-dan) Theory systematically in the former half of the 17th century. In its annotations, there are many quotes about Taoist books and figures, which leads to an estimation that the Chinese Taoist ideology must have exercised its influences on the formation of his Internal Alchemy Theory. It is thus needed to compare it with the Chinese Taoist ideology to have a clear picture of its characteristics and significance. The first step of the comparative research involved the estimation of Taoist books that Gown must have consulted and the examination of circumstances around Taoist books circulated in Joseon through the quotes in his Juhae, which were categorized into the ones that began with a book title, those that began with a name, and those that began in "In an old poem." They were compared with those of Dojang, and the results show that Gwon must have consulted various annotation books of Chamdonggye including Chamdonggyebalhui and various Taoist books including Gyujungjinam and Geumdandaeyo. The investigator then looked into Taoist books circulated in Joseon at the time when Gwon wrote Juhae and found a circumstance of circulation of annotation books of Chamdonggye by three families including Yu Yeom and collections of Taoist books including Doseojeonjip and Sujinshipseo. They were then compared with the Taoist books in the quotes of the author, and the results show that most of his quotes contained the Taoist books of Doseojeonjip. That is, the specific circumstances of books circulated in the former half of Joseon were clearly revealed in the quotes of Juhae. Of the Taoist books found in his quotes, Jin Chi-heo was most quoted, being followed by Jang Baek-dan, Seol Do-gwang, Jin Nam, Baek Ok-seom, and So Jeong-ji. It thus seems that Gwon was under the huge influence of Internal Alchemy Theory of Jin Chi-heo and Nam Jong.

The cyber battlefield called the fifth battlefield, is not based on geological information unlike the existing traditional battlefiels in the land, sea, air and space, and has a characteristics that all information has tightly coupled correlation to be anlayized. Because the cyber battlefield has created by the network connection of computers located on the physical battlefield, it is not completely seperated from the geolocational information but it has dependency on network topology and software's vulnerabilities. Therefore, the analysis for cyber battlefield should be provided in a form that can recognize information from multiple domains at a glance, rather than a single geographical or logical aspect. In this paper, we describe a study on the development of the cyber operation COP(Common Operational Picture), which is essential for command and control in the cyber warfare. In particular, we propose an architecure for cyber operation COP to intuitively display information based on visualization techniques applying the multi-layering concept from multiple domains that need to be correlated such as cyber assets, threats, and missions. With this proposed cyber operation COP with multi-layered visualization that helps to describe correlated information among cyber factors, we expect the commanders actually perfcrm cyber command and control in the very complex and unclear cyber battlefield.

In this paper, we propose an unmanned vehicle scratch detection deep learning model for car sharing services. Conventional scratch detection models consist of two steps: 1) a deep learning module for scratch detection of images before and after rental, 2) a manual matching process for finding newly generated scratches. In order to build a fully automatic scratch detection model, we propose a one-step unmanned scratch detection deep learning model. The proposed model is implemented by applying transfer learning and fine-tuning to the deep learning model that detects changes in satellite images. In the proposed car sharing service, specular reflection greatly affects the scratch detection performance since the brightness of the gloss-treated automobile surface is anisotropic and a non-expert user takes a picture with a general camera. In order to reduce detection errors caused by specular reflected light, we propose a preprocessing process for removing specular reflection components. For data taken by mobile phone cameras, the proposed system can provide high matching performance subjectively and objectively. The scores for change detection metrics such as precision, recall, F1, and kappa are 67.90%, 74.56%, 71.08%, and 70.18%, respectively.
