This paper studies the method of estimating power loss and classifying the factors for improving the power generation efficiency through O&M. It is installed under various climatic conditions worldwide, operational and maintenance technologies suitable for the characteristics of the installation location are required. Existing studies related to solar power generation efficiency have been actively quantifying the impact on short-term losses by environmental factors such as high temperature, dust accumulation, precipitation, humidity, and wind speed, but analysis of the overall impact from a long-term operation perspective is limited. In this study, the potential for efficiency improvement was analyzed by re-establishing a loss classification system according to the power flow of solar power to derive a comprehensive efficiency model for long-term operation and estimating power loss through a case study for each region where climate conditions are classified. As a result of the analysis, the average annual potential for improving soiling loss was 26.9%, Death Valley 7.2%, and Seoul 3.8%. Aging losses was 6.6% in the 20th year as a cumulative. The average annual potential due to temperature loss was 2.9 % for Doha, 1.9% for Death Valley, and 0.2% for Seoul.

A new approach to the use of rice straw as a difficult-to-recycle agricultural waste was proposed. Potassium aluminosilicate was obtained by spark plasma sintering as an effective material for subsequent immobilization of ¹³⁷Cs into a solid-state matrix. The sorption properties of potassium aluminosilicate to ¹³⁷Cs from aqueous solutions were studied. The effect of the synthesis temperature on the phase composition, microstructure, and rate of cesium leaching from samples obtained at 800-1000 ℃ and a pressure of 25 MPa was investigated. It was shown that the positive dynamics of compaction was characteristic of glass ceramics throughout the sintering. Glass ceramics RS-(K,Cs)AlSi₃O₈ obtained by the SPS method at 1000 ℃ for 5 min was characterized by a high density of ~2.62 g/cm³, Vickers hardness ~ 2.1 GPa, compressive strength ~231.3 MPa and the rate of cesium ions leaching of ~1.37 × 10^-7 g cm^-2·day^-1. The proposed approach makes it possible to safe dispose of rice straw and reduce emissions into the atmosphere of microdisperse amorphous silica, which is formed during its combustion and causes respiratory diseases, including cancer. In addition, the obtained is perspective to solve the problem of recycling long-lived ¹³⁷Cs radionuclides formed during the operation of nuclear power plants into solid-state matrices.

This paper is written to introduce and review Shinji Matsunaga's The Aesthetics of Video Games which published in Japan in 2018. Shinji Matsunaga has studied video games from a philosophical and aesthetic perspective. In The Aesthetics of Video Games, he took video games as a hybrid form of traditional games. Shinji Matsunaga particularly notes that video games can design human behaviors and experiences. From this point of view, he tries to construct a theoretical framework that will be able to describe the ways of signification in games and fiction respectively. In previous studies, video games have been mainly discussed in the context of cultural studies and entertainment culture in Japan. The Aesthetics of Video Games is distinguished from the previous studies in the following points. First, The Aesthetics of Video Games pioneered the method of studying video games in art theory. Second, it established various types of relationships with video games and traditional aesthetic concepts. Third, this book connects new concepts that emerged in the age of artificial intelligence to video games as an aesthetic action. Through this work, not only video games were discussed academically, but also the fields of aesthetics and art were expanded. The Aesthetics of Video Game is like a collection of philosophical concepts for video games. Through this book, it can be said that the path for artificial intelligence to approach human secrets is closer than before.

This study explores the importance of semantic web-based network construction in art data archiving, as well as its meaning and value in the context of arts management along with its potential for future application. The study focuses on oral history obtained from the Arko Arts Archives that contained records of the lives and artistic views of early artists. In this study, the possibility of applying semantic web-based technology to materials concerning culture and the arts was discussed in five aspects based on the results of the case analysis. First, checking the relationship and discovering hidden artists are possible by revealing relationships between characters. Second, understanding and studying society and culture at a given time is possible by interpreting the contextual meaning of information. Third, art exploration can be done broadly and deeply, encompassing various genres from the perspective of the consumer. Fourth, through art construction, history can be reconstructed using a new and rich method. Fifth, expanding the scope beyond the boundaries of art is possible through convergence and collaboration of programs that handle big data. The network data can be used in various methods, such as art history research, art planning, and creation, throughout the art ecosystem. The results of the study suggest that digitizing a large quantity of data concerning culture and the arts is meaningful in arts management as well as identifying and analyzing the relationship network among data clusters using semantic web-based technology.

Background and objective: Plants in temples are the results of cultural symbolization that embraces the experience and enlightenment of humans about life. As a way to improve the acceptance of the foreign religion, China gave cultural symbolization to plants in temple gardens through integration with traditional cultures and the understanding of the nature of plants themselves. This study aimed to identify cultural symbolism and signs of acculturation associated with Buddhist plants, targeting Bolisu, the most essential and symbolic plant in temple garden forests in China and Korea. Methods: The morphological and ecological characteristics of plants, functions, the texts that contained the history of Buddhism and literary works were examined through literature review, and the relation of Ficus religiosa with its planting conditions and nature, and Buddhist culture was explored. In addition, the cultural value of Buddhist plants themselves in establishing temples and the reason why Bolisu was planted in temples were reviewed through time series analysis. The obtained results were interpreted using an inductive method to identify substitutes for F. religiosa, cultural symbolism and signs of acculturation. Results: F. religiosa as one of the three holy trees and the five trees and six flowers in Buddhism is known as the original Bolisu. Since it grows well and is widely distributed in regions that accepted Indian Buddhism, it became the most representative holy tree in Buddhism. From the perspective of tree shape and nature, F. religiosa is in line with the Buddhist spirit of saving those in need with mercy and redeeming mankind, and figuratively shows that perfection can be attained like the fruit of Bolisu. Chines Buddhism had adopted highly symbolic plants for a long period of time as a means to spread the same belief and doctrines as Indian Buddhism. In China, however, there were only limited areas suitable for the growth of F. religiosa, and for this reason, borrowed Bolisu trees including Tilia. miqueliana, T. mandshurica and T. amurensis and other plants such as F. virens Ait. var. sublanceolata, G. biloba and M. alba were planted as a substitute in most regions, having been given with symbolism and belief as Bolisu. Conclusion: Chinese Buddhism planted the same plants as Indian Buddhism in order to enhance symbolism and also similar substitutes to express the same symbolism. This is a kind of acculturation and its influence and customs were not limited to China, but were introduced to Korea, The difference between China and Korea was that G. biloba was excluded from the substitute for Bolisu in Korea.

The purpose of this study is to broaden the understanding of the Security Services Industry Act, and also to examine the meanings of various phenomena by analyzing the media report big data rather than the researchers' perspective on the Security Services Industry Act. In the research method, this study searched for a keyword 「Security Services Industry Act」 that prescribes the security work as an important subject of crime prevention and maintenance of public order in Korea. The data was searched from 1990 to 2021 the BIG KINDS could provide. Also, for the concrete analysis during the period of data search, it was divided into settlement period(1976~2001), growth period-quantitative(2002~2012), and growth period-qualitative(2013~2021). In the results of this study, the media report perception of the Security Services Industry Act is continuously emphasizing the social roles and importance of private security according to the flow of time. The consequent marketability of private security will play great roles in the protection of people's lives and properties in the combination with various other industries in the future. However, the private security industry that provides public peace service together with the police, could be rising as an element that hinders the development of private security industry because of various social issues caused by legal regulations and illegal problems, so it would be necessary to more strengthen its responsibility and roles accordingly.

This study used a method of comparing and analyzing various editions of Jeokcheonsu, and aims to confirm why different views have arisen on commentaries that differ according to the perspective of one original text, which interpretation is more valid among them. The biggest part of the misunderstanding of Myeongri theory in Jeokcheonsu is Kyeokguk theory. Jeokcheonsu does not set a high value on Kyeokguk, and it is highly regarded as the Myeongri classics that emphasizes Eokbuyongsin. However, as a result of classifying the original text by theory, we can see there are about 5 sentences that directly mention Eokbu theory, but 9 sentences that explain Kyeokguk theory and 15 sentences if we include the sentences that explain Jonggyeok and Hwagyeok. Even looking that metaphoric speech is mainly used, it is also clear that it's not a book written to be read by a beginner of Myeongri. This is Myeongri texts written to convey more profound logic and enlightenment to a person who has sufficient knowledge by having learned the principle of Myeongri. A single sentence of 'Jaegwaninsubunpyeonjeong Gyeomronsiksanggyeokgukjeong' would have been sufficient to explain the Kyeokguk theory, because it's written on the assumption of the reader's level. Among the later commentaries about the theory of Myeongri contained in Jeokcheosu, 4 persons'commentaries on the original text of 'Palkyeok', 'Gwansal', Sangkwan', 'Wolryeong', 'Saengsi', 'Cheongtak' related to Kyeokguk theory was compared and analyzed.

The purpose of this study is to analyze the narrative structure and types of films that has attracted more than 10 million viewers ('10 million films') among films released in Korea, and deal with the implications of the current Korean film industry. To this end, this study investigated the relationship between films and their narrative as a product of the film industry. To approach this, We dealt with the features of structuralist analysis and archetype or mythological narrative analysis. For a detailed analysis, a total of 27 films of "10 million films" were categorized using Northrop Frye's original narrative analysis method. As a result of the study, 13 comedy structures, 7 romance structures, 4 tragic structures, and 3 irony and satire structures. It was confirmed that the "comedy" and "romance" structures had a high percentage of all 10 million films, and occupied the top ranks in the box office rankings. In conclusion, this study confirmed the narrative rules and customs of films hitting Korean box offices, and through this, it was possible to examine a rough topography of the film consumption of the public in the Korean film industry. This can be said to provide a clue as to how the narrative of the film should be constructed when producing a film from an industrial perspective.
