"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.

Recently, the metaverse has been receiving a lot of attention. Metaverse means a virtual space, and various events can be held in this space. In particular, 360-degree video, a format optimized for the metaverse space, is attracting attention. A 360-degree video image is created by stitching images taken with multiple cameras or lenses in all 360-degree directions. When shooting a 360-degree video, a variety of shooting equipment, including a shooting staff to take a picture of a subject in front of the camera, is displayed on the video. Therefore, when shooting a 360-degree video, you have to hide everything except the subject around the camera. There are several problems with this shooting method. Among them, lighting is the biggest problem. This is because it is very difficult to install a fixture that focuses on the subject from behind the camera as in conventional image shooting. This study is an experimental study to find the optimal angle for 360-degree images by adjusting the angle of indoor lighting. We propose a method to record 360-degree video without installing additional lighting. Based on the results of this study, it is expected that experiments will be conducted through more various shooting angles in the future, and furthermore, it is expected that it will be helpful when using 360-degree images in the metaverse space.

With the recent development of hardware computing devices and software based frameworks, machine tasks using deep learning networks are expected to be utilized in various industrial fields and personal IoT devices. However, in order to overcome the limitations of high cost device for utilizing the deep learning network and that the user may not receive the results requested when only the machine task results are transmitted from the server, Collaborative Intelligence (CI) proposed the transmission of feature maps as a solution. In this paper, an efficient compression method for feature maps with vast data sizes to support the CI paradigm was analyzed and presented through experiments. This method increases redundancy by applying feature map reordering to improve compression efficiency in traditional video codecs, and proposes a feature map method that improves compression efficiency and maintains the performance of machine tasks by simultaneously utilizing image compression format and video compression format. As a result of the experiment, the proposed method shows 14.29% gain in BD-rate of BPP and mAP compared to the feature compression anchor of MPEG-VCM.

Objective : The purpose of this study is to present a case report with the adult patient who needed active treatment of pityriasis rosea with severe pruritus, and did not respond to steroid treatment in the preceding month. Methods : The subject is an adult patient with pityriasis rosea over the age of 40 without any other diseases. We administered Korean medicine treatment with Bangpungtongseong-san (防⾵通聖散) and acupuncture. The effects of the treatment were evaluated via scales including Pruritus score, Pityriasis Rosea Severity Score (PRSS), and picture. Results : After the treatment Pruritus score/PRSS index of the case changed from 8/20 to 0/0. No other severe adverse reactions were reported. No more recurrence or pruritus was confirmed in follow-up. Conclusions : Korean medicine treatment with Bangpungtongseong-san showed marked improvement in pruritus and skin symptoms of pityriasis rosea in need of active care. With the lack of existing clinical reports of pityriasis rosea, we found that Korean medicine treatment could be an effective way, and it is expected that Bangpungtongseong-san could be administered to pityriasis rosea patients. Randomized-controlled trial for further evaluation will be needed in the future.

The purpose of this study is to examine the practice of scientists from the perspective of Ian Hacking's 'creation of phenomena'. Scientific phenomena, according to Hacking, are regular and do not exist in nature without the intervention of scientists or experimental tools. This study tries to derive scientific educational meaning by analyzing the thoughts and episodes of the 'Sontanda (inter-individual variability)' phenomenon experienced by four life scientists. The Sontanda phenomenon is a common term used by scientists to describe phenomena in which findings do not appear consistently even when studies are carried out using the same experimental procedure and materials. The following four educational implications were discovered as a result of the research. First, we confirmed the importance of embodied knowledge, or non-verbal knowledge, which solves issues by making appropriate judgments and reactions at all times, rather than simply becoming accustomed to the experimental method. This argues that propositional knowledge and non-verbal knowledge should be handled equally in order to provide students with a practical scientific inquiry. Second, we tried to reconsider the picture of the experiment. The phenomenon revealed in the interviews of scientists is rare, and it takes a long time to stabilize the phenomenon. On the other hand, the image of school experiments is always positive and consistent, necessitating a shift in perspective. Third, the precise meaning of scientific practice could be confirmed. This study confirms that scientists use their knowledge effectively in line with the circumstances, and we examined strategies to apply scientific practice to school instruction based on this. Finally, by provoking uncertainty, the Sontanda phenomena may give students with an opportunity to engage in meaningful scientific involvement. By breaking away from the cookbook experiment, this study expects school experimental education to help in efforts to experience scientific practice.

The purpose of this study is an empirical case study that focuses on bring about changes in clients through narrative therapy using scaffolding. Through this, the purpose was to find the preferred values and hopes of the future among the stories that the client's has lived in. As the research method, we proceed through unstructured interview and loose structures in qualitative research. On this premise, the counselor did not diagnose or explain the 'decentralized but influential' attitudes and problem. And there was no order in the conversation, and I didn't decide in advance how to react to it before the client made any expressions. This study has the following significance on a practical and academic level: First of all, counseling through scaffolding further enrich the curiosity, temperament, and wishes of the client. Second, the scaffolding provides a concrete picture of the relationship between a counselor and a client in narrative therapy. Third, the scaffolding made in therapeutic dialogue presents a 'learning tasks'. Fourth, counseling through scaffolding has an active meaning that it can develop the higher mental function of clients in charge. Finally, we presented an application of narrative therapy in Vygotsky's theory through analysis of empirical cases. Based on this information, this study did not simply intend to position the client as a research object in narrative therapy. It is meaningful that they have identified the factors necessary to become the subject of narrative therapy and the role of the counselor in the process. In addition, this study has implications in that it contributed to the expansion and substantialization of the research scope of narrative therapy in that it utilized the concept of scaffolding, which has not received much attention in the domestic research.
