This study begins with the question of how culture-based communities can form a community culture and become a community of sustainable development. Based on the concept of community, community development factors and stage of development, cultural activities, and policy implementation theory, policy execution analysis models suitable for culture-based community projects were derived. A qualitative case study method was adopted as a research method, and success stories of culture-based village communities were selected as the 'Gamgol Community' in Sadong, Ansan, 'Sangdong Community' in Daebu-dong, Ansan, and 'Grimae Village' in Sinse-dong, Andong. Through in-depth interviews, literature analysis, and direct observation, the research analysis used pattern matching, explanation, chronicle analysis, and case integration analysis methods presented by Yin (2009). As a result of the study, first, the characteristics of the policy implementation strategy were taking place in the process of step-by-step development. The main factors in the community development phase were the improvement of community consciousness through the emotional change of participants and the change of capacity within the community. Second, it was understood that cultural activities played a major role in strengthening community consciousness and community capacity, and could be understood as various creative activities. Based on the ecological approach study on culture-based community, this study derived the policy execution analysis model, analyzed the case of culture-based village community, presented the direction of development of community and presented practical implications.

The purpose of this study is to propose a book recommendation system that can be used in school libraries. The book recommendation system applies an algorithm based on association rules using DLS lending data and is designed to provide personalized book recommendation services to school library users. For this purpose, association rules based on the Apriori algorithm and betweenness centrality analysis were applied and detailed functions such as descriptive statistics, generation of association rules, student-centered recommendation, and book-centered recommendation were materialized. Subsequently, opinions on the use of the book recommendation system were investigated through in-depth interviews with teacher librarians. As a result of the investigation, opinions on the necessity and difficulty of book recommendation, student responses, differences from existing recommendation methods, utilization methods, and improvements were confirmed and based on this, the following discussions were proposed. First, it is necessary to provide long-term lending data to understand the characteristics of each school. Second, it is necessary to discuss the data integration plan by region or school characteristics. Third, It is necessary to establish a book recommendation system provided by the Comprehensive Support System for Reading Education. Based on the contents proposed in this study, it is expected that various discussions will be made on the application of a personalization recommendation system that can be used in the school library in the future.

COVID-19 has caused the dramatic reduction of public transportation demand in Busan Metropolitan City, that is, daily public transportation trips in 2020 dropped by approximately 920,000 trips from 2019 based on the public transportation card data. This study investigated the underlying factors affecting the public transportation demand discrepancy between before and after COVID-19 at the primary administration unit(i.e., Eup, Myeon, Dong) level with Ordered Logistic Regression model. Finding of this study is as follows. The primary administration units characterized with high ratio of welfare recipients, industrial area, and day boarders were heavily dependent on public transit, indicating little change in public transportation demand. On the other hands, the primary administration units which have high ratio of urban rail transit uses experienced significant reduction of public transportation demand. In conclusion, transportation policies taken under emergent situation such as COVID-19 need to take into account the region-based characteristics rather than unilateral ones.

우리나라 농업용 저수지는 저수량만을 참조하여 운영한다. 이러한 현실을 개선하기 위해, 유입량을 고정시키고 저수지 물수지 분석에 의해 방류량을 생산하는 체계를 구축했다. 2018년부터 2021년까지 총저수량 142만m³의 옥서저수지, 106만m³의 홍동저수지에 적용하여 일별로 저수량을 모의하여 관측값과 비교하고, 저수지 물수지 분석에 의해 실시간 계측되는 수로유량의 신뢰도를 평가하였다. 장기간의 계측 자료를 보유하고 있는 인근 다목적댐인 보령댐의 운영자료(2018~2021)를 이용하여 유입량 모형의 매개변수(α=3.500)를 결정하고, 저수지 유입량을 모의한 결과 NSE 0.854, R² 0.858의 높은 신뢰도를 얻었다. 유입량을 고정시키고, 저수지 물수지 분석에 의해 방류량을 계산한 결과 옥서저수지는 일최대 방류량 5.7m³/s, 일평균 0.2m³/s, 홍동저수지는 각각 5.9m³/s, 0.2m³/s로 나타났다. 총방류량을 측정 수로유량과 여수로 방류량으로 분할하고, 저수지 물수지 분석에 의해 수로유량의 신뢰도를 평가한 결과 옥서저수지는 R²가 0.771, 일평균 저수위 오차 88.6cm, 일평균 저수량 오차 9.4%, 홍동저수지는 R²가 0.086, 일평균 저수위 오차 69.9cm, 일평균 저수량 오차 18.0%로 오차가 크게 나타났다. 저수지 수위가 만수위(FWL) 이하일 때는 여수로 방류량을 0으로 하여 총방류량을 여수로 방류량과 수로유량으로 분할한 후, 물수지 분석에 의해 신뢰도를 평가한 결과, 옥서저수지의 경우 R²는 0.941, 일평균 저수위 오차 2.6cm, 일평균 저수량 오차 0.35%를 나타내, 신뢰도가 크게 증가했다. 그러나 홍동저수지의 경우는 R²는 0.521, 일평균 저수위 오차 2.2cm, 일평균 저수량 오차1.02%를 나타냈지만, 낮은 신뢰도를 보였다. 측정 수로유량의 신뢰도는 두 저수지 모두 낮게 나타났다. 수로유량 조정을 통해 옥서저수지의 신뢰도는 향상 시킬 수 있었지만 홍동저수지의 경우는 향상 시킬 수 없었다. 이는 여수토 비상수문조작 실적과 저수지 사통 수문 조작 실적이 없어, 그 결과를 정확히 반영할 수 없었기 때문인 것으로 결론을 내렸다.

Modeling of artificial targets in Synthetic Aperture radar (SAR) mainly simulates radar signals reflected from the faces and edges of the 3D Computer Aided Design (CAD) model with a ray-tracing method, and modeling of the clutter on the Earth's surface uses a method of distinguishing types with similar distribution characteristics through statistical analysis of the SAR image itself. In this paper, man-made targets on the surface and background clutter on the terrain are integrated and made into a three-dimensional (3D) point cloud scatterer model, and SAR image were created through computational signal processing. The results of the SAR Stripmap image generation of the actual automobile based SAR radar system and the results analyzed using EM modeling or statistical distribution models are compared with this 3D point cloud scatterer model. The modeling target is selected as an bridge because it has the characteristic of having both water surface and ground terrain around the bridge and is also a target of great interest in both military and civilian use.

The purpose of this research is to explore the relation between Brexit and division in various areas within the British society. This research can lead to understanding how division of the British society and the decision of Brexit was mutually influenced. The UK's withdrawal from the EU has been explained mainly through the relations between the EU and the UK; therefore, issues of immigration, EU regulation, and the UK's EU rebate are considered as major reasons. In addition, 'British identity' or 'British exceptionalism' existing in the British society and politics for a long time has been regarded as a reason for Brexit. Although it is generally accepted that Brexit results in the division in the British society, the reasons mentioned above have limitation to explain the result of referendum and the division of the British society in the post-Brexit era. In this sense, this research explores the division in various areas - generation, social grade including income and education level, value and region, etc. - revealed in the British society is not the result of Brexit; rather, this research argues division deeply rooted in the British society before referendum is the root cause of Brexit. The division in various areas immanent in the British society for a long time is complicatedly intertwined, and the decision on Brexit by referendum has led to solidifying the division of the British society. Having considered this division in the British society has been expanded to rancour, it is necessary for the UK to establish appropriate policies for national cohesion.

In this paper, I looked for the parts where laughter appeared in the Mundoong, Yangban, Yeongno, and Grandfather and Grandmother of Tongyeong Ogwangdae and Dongrae Yaryu, and investigated the meaning of those parts. Laughter in mask play has made him more tolerant of human injustice and foolishness. I softened the critical content and naturally revealed what I thought should be hidden. Through a short and noisy plot, the opposing forces, the inner conflict of the Mundoong, Yangban, Yeongno, and Grandfather and Grandmother were shown in a realistic and realistic way. The worldview that creates the structure of realism is typically skeptical and ironic, and the worldview that creates the comical structure related to laughter aims for the ultimate emergence of a new order based on unity and harmony. Masking is thought to be a work in the stage of moving from the latter to the former. Therefore, it is judged that laughter in mask play served as an important medium for Korean art thought to have a realist view of the world. This is because various expression methods that induce laughter are working to reveal negativity, reveal the illusion of contemporary values, and naturally expose restraint and taboo suppression. In laughter, there is a path that transforms perception by fusing several elements. There was realism at the end of the pathway to new perception.

Underground Geospatial Information Map Management System(UGIMMS) integrates various underground facilities in the underground space into 3D mesh data, and supports to check the 3D image and location of the underground facilities in the mobile app. However, there is a problem that it takes a long time to run in the app because various underground facilities can exist in some areas executed by the app and can be seen layer by layer. In this paper, we propose a deep learning-based K-means vertex clustering algorithm as a method to reduce the execution time in the app by reducing the size of the data by reducing the number of vertices in the 3D mesh data within the range that does not cause a problem in visibility. First, our proposed method obtains refined vertex feature information through a deep learning encoder-decoder based model. And second, the method was simplified by grouping similar vertices through K-means vertex clustering using feature information. As a result of the experiment, when the vertices of various underground facilities were reduced by 30% with the proposed method, the 3D image model was slightly deformed, but there was no missing part, so there was no problem in checking it in the app.
