This paper has two goals: first, I will analyze the current research trend of studying the Nosa School, which is composed of Ki Jeongjin(1798~1879) and his students and then, provide with some tasks we have to solve. The Nosa Studies, which I suggest here, means the one that the scholarship and thought of Ki Jeongjin, one of the six masters and the representatives of neo- Confucianism in late Choson Korea, and all kinds of academic achievements, which had been succeeded and established by his students. Their diverse activities as well as scholarship play crucial roles in both modern Korean Confucianism and Dao Studies in late Choson Korea. Ki's core thought is a conclusion of various issues, which had been raised since Korean Confucianism of Toegye and Yukgok. Their diverse activities kicked into high gear after Ki's death can be understood as one of remarkable cases, which was how to be transformed by encounters with realities in modern Korea. Especially, some controversies and responses to practical issues that linked with their philosophical values of the Nosa Studies in Kiho school in early twentieth century will be a criterion to shed light on the identity of Korean Confucianism today. Thus, I will summarize the content of researches on the Nosa Studies, which begins to appear in the early-mid twentieth century, through an overview of the Nosa Studies, examine research results by dividing part by part, and provide with some prospects and tasks, which are based on what I mention above.

A Buddhist relic deposit was discovered from the three storied stone pagoda which was called as Seokgatap of Bulguksa temple in Gyeongju in 1966. In this relic deposit, several clumped papers written in ink which were found from the pagoda. These manuscripts are one of the most valuable materials for understanding Korean Buddhism and Buddhist Art History. In this paper, I examined several terms for pagoda subsidiaries found in these manuscripts, which have not been known to us up to recently. In addition, I compared these terms to the real pagodas or pagoda images in Korea. The manuscripts from Seokgatap pagdoa were composed of three different kinds of records; (1) "Record for the Repair of Mugujeonggwangtap Pagoda (無垢淨光塔重修記, 1024)"; (2)"Record for the Reconstruction of West Pagoda (西石塔重修形止記, 1038); (3)"Lists of Donors for the Reconstruction of the Pagoda in Bulguksa temple (佛國寺塔重修布施名公衆僧小名記, 1038). The terminology describing pagoda was appeared in the first and the second records. In the "Record for the Repair of Mugujeonggwangtap Pagoda", there are more than ten terms, which are presumed to be the words describing some upper decorative parts of a stone pagoda. However, in the "Record for the Reconstruction of West Pagoda", there are fifteen terms which would describe the body and base parts of the Seokgatap pagoda. These new terms for pagoda subsidiaries appeared in the manuscripts of Seokgatap Pagoda are very significant materials in understanding Korean Buddhist Art, because they show the practical terms which were used in the eleventh century Buddhism of Korea, but never known to the modern academic world. The manuscripts of Seokgatap Pagoda have not been deciphered perfectly yet, so they have to be examined with more precise as well as with wider view of Buddist and Art History.

This paper attempted to explore the basic concept of a website for start-up supports angled towards North Korean defector entrepreneurs. The position of this study was made clear by reviewing the existing literature, and the case study was carried out to make sure the results are essential to create the services vital for the North Korean defector's entrepreneurial ecosystem. Focusing on the fact that there is not yet a website for supporting North Korean defectors' start-up in Korea, an early version named "Prometheus" was designed. A revised version called "Pathfinder" followed with improvements. This study conducted academic and practical experiments by directly designing and implementing a medium that can boost the development of the start-up ecosystem of North Korean defectors based on the insights provided by North Korean (future)business owners and South Koreans interested in the start-up ecosystem of North Korean defectors. Taking this study as an opportunity both the research to further clarify the "start-up of North Korean defectors," a very special phenomenon that exist in Korea, and the research for practical contribution should be encouraged in various ways. These efforts will not only help North Korean defectors start-up businesses, and also play a role in boosting a sense of coexistence and cooperation within North Korean defectors community.

In this paper, we propose a novel recommendation model based on Doc2vec using search keywords and product details. Until now, a lot of prior studies on recommender systems have proposed collaborative filtering (CF) as the main algorithm for recommendation, which uses only structured input data such as customers' purchase history or ratings. However, the use of unstructured data like online customer review in CF may lead to better recommendation. Under this background, we propose to use search keyword data and product detail information, which are seldom used in previous studies, for product recommendation. The proposed model makes recommendation by using CF which simultaneously considers ratings, search keywords and detailed information of the products purchased by customers. To extract quantitative patterns from these unstructured data, Doc2vec is applied. As a result of the experiment, the proposed model was found to outperform the conventional recommendation model. In addition, it was confirmed that search keywords and product details had a significant effect on recommendation. This study has academic significance in that it tries to apply the customers' online behavior information to the recommendation system and that it mitigates the cold start problem, which is one of the critical limitations of CF.

In North Korea, where there was little external activity, the number of overseas academic paper publications has recently increased. This study aims to quantitatively analyze North Korean papers published abroad to identify changes in North Korea's research and development trends, and to explore the possibility of developing them through joint research with domestic researchers in the future. To this end, since 1986, frequency analysis and network analysis have been conducted on papers published overseas including North Korean researchers. The analysis was conducted on authors, research institutes, countries, and research fields, and changes were analyzed before and after Kim Jong-un took office. According to the results of the analysis, as the number of foreign papers published rapidly increased during the eight years after Kim Jong-un took office, the composition of the top researchers, research institutes, and researchers with high influence in joint research also changed a lot. After Kim Jong-un came to power, the proportion of North Korean researchers and research institutes increased relatively, and a network component was formed between researchers with high influence on joint research, so it was observed that they focused on specific research topics. It was found that the major foreign collaborators or research institutes of North Korean researchers were from China.

In this paper, an exploratory analysis study was conducted on establishing a strategy to utilize living labs to enhance the innovation of the energy sector. Through the previous research literature, it was possible to confirm the concept, essential components, innovation characteristics of living labs, and types of innovation issues in the energy sector as the theoretical background. Based on this, the case studies of energy living lab (8 overseas, 1 domestic) were analyzed focusing on the possibility of utilizing living lab as an approach to innovation issues in the energy sector, establishing a customized strategy for essential components of living lab and enhancing innovation. It was confirmed that the establishment of a customized strategy for the essential components of the living lab could be a driving force in enhancing innovation, and the Living Lab is effectively used as an approach method for innovation issues(demand management, supply technology, enhance R&D acceptance and promote commercialization, technology policies) in the energy sector. As a result of the case studies, the driving force of each living lab was derived from the viewpoint of contributing to innovation, and strategies for using the living labs for each energy innovation problem were established. This study is an exploratory and descriptive analytical study of the utilization strategy and value of the living lab model as an approach to innovation issues in the energy field, which can provide a living lab strategy framework that has not been tried in the past and enables living lab activation and network formation. It can also be considered to have academic, practical, and policy implications in that it can also contribute.

Recently, the keyword 'convergence' has emerged in the education field. The voice of demand for the humanities is also increasing. The range of convergence of the humanities is gradually spreading to various fields such as science, technology, engineering, and the arts field. And also, the trend is to nurture the future creative convergence talent with logical, comprehensive, and creative thinking through the fusion of humanities, scientific, and empirical theories. Myths and legends contain the content of humanity's culture creation and deal with matters such as religion, philosophy, art, and science. Therefore, through the consciousness of the ancients who lived in the so-called convergence era when academic differentiation did not occur, it will be possible to reflect on the appearance of sages. In this paper, we propose a method for educating Chinese culture through the analysis of by Wen Yi-Duo, a famous Chinese scholar. He sought to find the origin of Chinese culture through myths and legends and to find national identity by restoring the concept of national culture in the period of origin. The myths and legends of China are closely related to the cultural phenomena of modern China, which will further enhance our understanding of China.

Recently, the method of contacting and purchasing NFT art has been popularly evolving, and various prospects and predictions for NFT art have emerged. The discussion of NFT art is mainly a hot topic in terms of market size, profit, and sustainability. As the transition to digital accelerated after COVID-19, almost all genres of culture and arts faced a forced transition with the topic of combining digital and technology, but in terms of profitability, it was generally difficult to guarantee positive continuity. On the other hand, the combination of art and blockchain, and the new distribution method called NFT, attracted a lot of attention by causing fundamental changes that lead to technological transformation, continuity through profit creation, and even genre expansion of visual art. The discourse on NFT and the art market is a recent phenomenon and is being discussed focusing on statistics and numerical reports through data from newspapers and art-related research institutes rather than academic analysis or research. However, discussions related to NFT art should be considered in various aspects, such as the incorporation of technology and art, changes in distribution methods, and changes in creative methods according to media changes, not just short stories of phenomena such as high prices and winning bids. In this paper, we would like to examine the impact of changes in creators and distribution methods.

This study aims to apply Hannah Arendt's concept of 'collective responsibility' to the Christian education on environmental issues around the world, focusing on climate change. This study prepares the concept of 'collective responsibility' and the concept of 'collective guilt' and emphasizes the fact that the current climate change problem should be seen as a political task rather than a task of personal ethics. According to Arendt's theory, Christian education activities applying 'collective responsibility' for climate change can become action. This study has four suggestions for Christian learning to understand and recognize climate change. First, presenting and justifying the anxiety and anger toward climate change in the classroom. Second, transcending self-interest (egocentrism) through "Common Sense (enlarged mentality)" in Kantian terms. Third, building education communities through 'citizen participatory education,' running communication, and conversation. Fourth, encouraging experience and practice in every education community with "faith expressing itself through love (Gal 5:6)." Then, to be sure, this refers to not only love of neighbor in Christianity but also political friendship (philia politikē). The academic significance of this study is that it is the first interdisciplinary research paper in Korea which dealt with Arendt's political theory in relation to Christian education. Although it claims to be a theoretical work that applies Arendt's political theory from a systematic theological perspective to Christian education, the author is proud that it is accompanied by practical elements that can be actualized in the education field.

Agriculture is the backbone of the economy of most developing countries. In these countries, agriculture or farming is mostly done manually with little integration of machinery, intelligent systems and data monitoring. Irrigation is an essential process that directly influences crop production. The fluctuating amount of rainfall per year has led to the adoption of irrigation systems in most farms. The absence of smart sensors, monitoring methods and control, has led to low harvests and draining water sources. In this research paper, we introduce a 433 MHz Radio Frequency and 2G based Smart Irrigation Meter System and a water prepayment system for rural areas of Tanzania with no reliable internet coverage. Specifically, Ngurudoto area in Arusha region where it will be used as a case study for data collection. The proposed system is hybrid, comprising of both weather data (evapotranspiration) and soil moisture data. The architecture of the system has on-site weather measurement controllers, soil moisture sensors buried on the ground, water flow sensors, a solenoid valve, and a prepayment system. To achieve high precision in linear and nonlinear regression and to improve classification and prediction, this work cascades a Dynamic Regression Algorithm and Naïve Bayes algorithm.
