In this paper, we propose a real-time virtual model synchronization algorithm using object feature detection. The proposed algorithm may be useful to synchronize between real objects and their corresponding virtual models through object feature search in two-dimensional images. It consists of an algorithm to classify objects with colors individually, and an algorithm to analyze the orientation of objects with angles. We can synchronize the motion of the real object with the virtual model by providing the environment of moving the virtual object through the hand without specific controllers. The future research will include the algorithm to synchronize real object with unspecified shapes, colors, and directions to the corresponding virtual object.

In general, golden time refers to the most important time in the initial response to accidents such as saving lives or extinguishing fires. The golden time varies from disaster to disaster, but is aimed at five minutes in terms of fire and first aid. However, for the actual site, the average dispatch time for ambulances is 9 minutes and the average transfer time is 17.6 minutes, which is quite large compared to the golden time. There are various causes for this delay, but the main cause is traffic jams. In order to solve the problem, the government has established emergency car concession obligations and secured golden time to prioritize ambulances in places with the highest accident rate, but it is not a solution in rush hour when traffic is increasing rapidly. Therefore, this paper proposed a deep learning-based emergency vehicle priority signal system using collected sound data by installing sound sensors on traffic lights and conducted an experiment to classify frequency signals that differ depending on the distance of the emergency vehicle.

We aimed to find new space types and characteristics for creating gardens in the city through the type of idle space in the city, present guidelines that can be used in creating gardens in the future, and establish basic data for expanding green infrastructure. As a result, we found that the idle space in the city was classified into four types, and it was determined that differentiation should be given to the creation of each type. The achievements of this study can be a potential source of urban ecosystem services that can provide community benefits and opportunities for urban regeneration through the redevelopment of the community and support the health and well-being of local residents. In addition, urban idle space can be a valuable resource as a green infrastructure that can be used to support the health of urban ecosystems and improve the quality of life of urban residents.

Content curation aims to limit the user's experience to the most necessary content; to do this, it is necessary to identify users' information needs. Given that KISTI's Content Curation Center was established in 2018, it had little information about its users. This study intends to investigate what content scientists want to see from KISTI and how they want it curated. It investigated researchers who worked for government-funded research institutes through online surveys and telephone interviews. This study's results helped me review the current practice of KISTI content curation and give some suggestions to improve future practice. They present information on content and content curation services required by researchers; therefore, they can be used as a reference for information agencies (e.g., libraries, data centers) to improve their content curation practices.

This paper presents a algorithm for automatic target recognition robust to the influence of the flame in order to track the target by EOTS(Electro-Optical Targeting System) equipped on UAV(Unmanned Aerial Vehicle) when there is aerial target or marine target with flame at the same time. The proposed method converts infrared images of targets and flames into a gradient vector field, and applies each gradient magnitude to a polynomial curve fitting technique to extract polynomial coefficients, and learns them in a shallow neural network model to automatically recognize targets and flames. The performance of the proposed technique was confirmed by utilizing the various infrared image database of the target and flame. Using this algorithm, it can be applied to areas where collision avoidance, forest fire detection, automatic detection and recognition of targets in the air and sea during automatic flight of unmanned aircraft.

Many kinds of ritual manual books for the four ceremonies (coming-of-age, wedding, funeral, and ancestral rites) were published and transcribed during the Japanese Colonial Period. The ritual manuals are classified by 5 different types: 'ritual standards', 'ritual books for the four ceremonies', 'ritual books for the written prayers', 'religious ceremonial books', and 'general manners books'. All of them contributed much to the formation of folk rituals and religions, even though the purpose and contents of each book were different. The ritual manuals were not intellectual results of elites, but rather compilations of pre-modern ritual books and contemporary manners. These were widely spread among the people with the help of modern printing techniques. The ritual manuals aimed at common readers who wanted to look for ritual references easily. They were not just made for the special upper class. We can understand the contexts and characteristics of folk ritual and religion of the $20^{th}$ century by comprehending the ritual manuals of the Japanese Colonial Rule.

The purpose of this study is to confirm the definition and the scopes of the implementation of Korean education for missionary purposes which is an area of ones for specific purposes and to suggest the teaching methods for each type by examining the subtypes of it. For this, a body of research and the related textbooks were analyzed: as a result, the definition of Korean education for missionary purposes was confirmed by examining the scope of implementation of it. Based on the definition, this study categorized the learners into four patterns such as non-Christian, the learners for listening gospel, the learners for nurturing, overseas Korean children and missionary kids according to the levels of Christianity literacy and briefly proposed the goals and teaching methods for each category. Finally, this study expected the development of the related textbooks and the activation of more segmented research in this area.

The purpose of this study is to analyze of the effect in Mathematics Teachers beliefs on their students beliefs by Latent Class Regression Model (LCRM). For this analysis, the study used the findings and surveys of Kang, Hong (2020) who developed a belief profile by analyzing the mathematical beliefs of 60 high school teachers and 1,850 second-year high school students learning from them through the Latent Class Analysis (LCA). As a result It was observed that 'Nature of Mathematics', 'Mathematic Teaching' and 'Mathematical Ability' of mathematics teachers beliefs influence the mathematical beliefs of students. The teacher's belief of 'Nature of Mathematics' statistically significant effects on students' beliefs in 'School Mathematics', 'Problem Solving', 'Mathematics Learning'. The teacher's belief of 'Teaching Mathematics', 'Mathematical Ability' statistically significant effects on students' beliefs in 'School Mathematics', 'Problem Solving', 'Self-Concept'. The results of this study can give a preview of the phenomenon in which teacher's mathematical beliefs are reproduced into student's mathematical beliefs. In addition, the results of observation of this study can be used to the contents that can achieve the purpose of reorientation for mathematics teachers.

In this study, the present state and characteristics of VR exhibits currently exhibited in Korea, Hong Kong, and Japan were studied to derive the improvements in the domestic VR exhibits. The previous literatures on VR exhibits at Science Museum were reviewed and online and offline data were collected, analyzed and compared. As the result of the study, VR exhibits at Science Museum in Korea turned out to focus on interest and fun rather than containing scientific content, and exhibits aimed at recreational play and physical activity. The Hong Kong Science Museum VR exhibits are more physically targeted exhibits than the cognitive target exhibits. In addition, at the Japanese Science Museum, there are many exhibits aimed at the physical target exhibits. As the result of classifying VR exhibits into the similar types, it was possible to derive them into four characteristics. The implications for future KOREA VR museum exhibitions were discussed.
