John Woo's A Better Tomorrow arrived at the turning point of Korean society between 1987 and 1988. The Hong Kong movie boom that started here reached its peak around the 1990s. What does this phenomenon mean? Hong Kong action films have functioned as an important resource for Korean young male subculture since the late 1960s. The audience of A Better Tomorrow matches the audience of previous Hong Kong films in a generational and gendered way. The fascination of Hong Kong action films by young Korean men from 1987 to 1991 has nothing to do with Hong Kong's political context. However, a certain affect is shared between Korean and Hong Kong audiences. It could be said to be the brotherhood within the struggling group. The affective economies of this fraternity embodies the broad solidarity of 1987, the solidarity of comrades seeking to resist the violence of the world. It also works on symbolic and practical gender bias. In other words, this loyalty is nothing but loyalty between the (male) brothers who are confronting the injustice of the world. This is the "translational possibility" of A Better Tomorrow.

This study explores differential value implications of R&D expenditure across firms, especially in terms of growth potential of small businesses. Analyzing Korean listed firms for the period from 1982 to 2014, we document the followings. First, large firms, defined as the top quintile group based on market capitalization, have spent higher R&D expenditure compared to small (bottom quintile group) and medium (middle quintile groups) firms and the difference between groups has enlarged over time. Relatedly, the persistence of R&D spending, measured by the association between current R&D expenditure and cumulative future R&D expenditure over the next five years, is lowest in small firms. Second, R&D of large (small) firms are more (less) likely to generate operating profits over the next five years. Additional analyses suggest that the relation between R&D and gross margin is strongest in large firms, suggesting that R&D underlies their competitiveness in the product market. Third, small firms have borne the highest uncertainty related to R&D investment proxied by the association between current R&D and volatility of future earnings. As a result, the likelihood of R&D leading to future patents is also lowest in small firms. Fourth, the probability of moving up to the next size group within the next five years is significantly lower in small firms than others. Finally, we find that the divergence in R&D expenditure between large and small firms is positively associated with product market concentration. Overall, our findings confirm the small business growth trap in relation to R&D investment.

As the importance of documented fact has weakened in historical dramas, the combination with other genres has become prominent. By reviewing the way romance is dealt with in historical dramas, this research examines how the properties of historical events adopted by historical dramas are related to the motif of love, and how the narrative of love and romance contributes to the historical effects, with a focus on the television drama Mr. Sunshine. Mr. Sunshine is the first historical drama written by Kim Eun-sook, combining deliberately rearranged history with the writer's unique grammar of romance. The failed resistance movement of the righteous army in the drama is matched with the love that cannot be achieved based on self-negation. The drama, which deals with the tyranny of Japanese imperialism and the independence of Joseon, fictionalizes key characters and events, transforming the desire of love into the passion of patriotism. Romance in Mr. Sunshine serves as a catalyst for emphasizing the tragedy of historical events and reconstitutes cultural memories. In historical dramas, the fictional plot of romance leads viewers to reflect on human life in history that flows from the past to the future. How does an individual's inner feelings contribute to the historical representation? This research is significant as it is the first attempt to examine the relationship between historical drama and romance in various ways.

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.

This study explored the possibility of introducing modern physics into the elementary school science curriculum. The study discussed the need of introducing modern physics to elementary school students and examined the results of certain projects and studies on teaching modern physics to elementary school students. Furthermore, this study proposes several teaching and learning techniques to introduce modern physics into the elementary school science curriculum. Modern physics can be linked to various everyday situations experienced by students and can increase their interest and curiosity in science. Additionally, introducing modern physics to elementary school students who are yet to establish a background on the classical view of nature can help them build a new perspective. Recently, several global projects to introduce modern physics at the elementary level have also reported positive results regarding the increase in student understanding and interest in modern physics. The study briefly proposed specific topics and teaching and learning techniques that could be suitable for the elementary school level. These proposals are expected to advance discussions on the possibility of introducing modern physics. However, appropriate follow-up studies are warranted to confirm the possibility and effectiveness of this initiative.

In the early 20th century, Korean Protestant Christians began two forms of prayer, Tongsung Kido and Dawn Prayer. The two prayers have been loved and performed by Korean Protestants for over 100 years. Speaking in tongues was introduced in the 1950s and became one of the most popular prayers along with Tongsung Kido and dawn prayer. Korean Protestant churches started Bible meditation in the 1970s through journals like the Daily Bible of the Scripture Union Korea. Now contemplative prayer appears as an unfamiliar and strange style of prayer, given the history of prayer so far in Korean churches. Protestant scholars and pastors have made this into a controversy; contemplative prayer is the first non-protestant prayer that has become controversial. The controversy is mainly about biblical origin, theological relevance, and historical and traditional conformity. This study asks and answers why this controversy is important for Korean Protestant churches. This study introduces the controversy and explores why one group accepts the prayer and others do not. Then, this study recounts the history of Korean Protestant prayers and shows the meanings of the encounter of Korean Protestant prayers and contemplative prayer. This study argues that Korean Protestant Christians, through the controversy, can learn that Korean Protestant churches have the potential to create a new prayer culture and tradition and need spiritual discipline through silence.

Purposes: Prompt evaluation of routes and contact tracing are very important for epidemiological investigations of coronavirus disease 2019 (COVID-19). To ensure better adoption of contact tracing apps, it is necessary to understand users' expectations, preferences, and concerns. This study aimed to identify main reasons why people use the apps, appropriate services, and basis for voluntary app services that can improve app participation rates and data sharing. Methodology/Approach: This study conducted an online survey from November 11 to December 6, 2020, and received a total of 1,048 survey responses. This study analyzed the questionnaire survey findings of 883 respondents in areas with many confirmed cases of COVID-19. This study used a multiple regression analysis. Findings: Respondents who had experience of using related apps showed a high intention to use contact-tracing apps. Participants wished for the contact tracking apps to be provided by the government or public health centers (74%) and preferred free apps (93.88%). The factors affecting the participants' intention to use these apps were their preventive value, performance expectancy, perceived risk, facilitative ability, and effort expectancy. The results highlighted the need to ensure voluntary participation to address participants' concerns regarding privacy protection and personal information exposure. Practical Implications: The results can be used to accurately identify user needs and appropriate services and thereby improve the development of contact tracking apps. The findings provide the basis for voluntary app that can enhance app participation rates and data sharing. The results will also serve as the basis for developing trusted apps that can facilitate epidemiological investigations.

One of the interesting social phenomena in short-form video platforms is the hashtag challenge wherein ordinary users are encouraged to create by imitating short viral videos on a particular theme. Despite the increasing popularity of hashtag challenges, theoretical discussion on related user behavior is still very insufficient. In this study, we attempted to examine the impact of micro-influencers in order to understand users' willingness to participate in hashtag challenges. For this purpose, the para-social interaction theory and imitation behavior literature were adopted as key theoretical basis. In an empirical investigation using 243 survey data from TikTok users, our study found that a user's illusion of intimacy with a micro-influencer (i.e., para-social interaction) had significant positive impact on the intention to participate in a hashtag challenge. This study also showed that the degree of para-social interaction in a short-form video platform was determined by both media content-related factors and media character-related factors (i.e., content attractiveness, physical attractiveness, and attitude homophily). Our work in this study provided significant theoretical and practical implications on how to leverage micro-influencers for the success of hashtag challenges in a short-form video platform.

Korean ginseng, a special product of Korea, has been one of the most important exports since the era of the Three Kingdoms. However, not many records were kept about ginseng in Korea until the Goryeo Dynasty. This paper summarizes the records relating to international diplomatic relations and trade of ginseng in the Goryeo Dynasty and the medicinal books known to have been published at the time. During the Goryeo Dynasty, ginseng was actively transported to the neighboring countries of Bohai, Song, Wa, Later Jin, and Yuan as a diplomatic gift or as a trade item. Ginseng was mainly exported from Goryeo to these countries, but it was also received as a diplomatic gift from Bohai and Khitan. Arabian merchants came to Byeokran Port, a representative international trading port of Goryeo, and traded ginseng. After the Mongol invasion, the demand for ginseng in the Yuan Dynasty was excessive, which became a big social problem. During the Goryeo Dynasty, several medicinal books were published, including Jejungiphyobang, Eouuichwalyobang, Hyangyakgobang, Samhwajahyangyakbang, Hyangyak Hyemin Gyeongheombang, Hyangyak Gugeupbang, and Biyebaekyobang. Hyangyak Gugeupbang, which was reprinted during the Joseon Dynasty, has been handed down to the present time, although this has not been the case for the originals of the remaining books. Recently, some of the latter books have been restored through the study of the references in various medicinal books of later generations. While the medicinal books used in the royal court showed that a high proportion of the prescriptions containing ginseng, not a single prescription for ginseng has been found in theHyangyak Gugeupbang, which was mainly used for commoners. This is thought to be because ginseng was very rare and expensive at the time, so it was difficult for commoners to access it.

Photovoltaic power generation is the most familiar power generation facility among new and renewable energies, and its supply began to expand about 10 years ago, and at this point, interest in solutions and technologies for system maintenance management is increasing. In particular, it is necessary to take measures to maximize the overall efficiency of the solar power generation system, whether or not there is an abnormality in the solar power generation system, and when to replace parts. The PV inverter, one element of the photovoltaic power generation system, is a power conversion system that relies on power switching devices, and DC-Link capacitors are used according to the configuration of DC/DC converters and DC-AC inverters. These DC capacitors also affect system safety (Safety) through renewable energy facilities due to the decrease in power generation of PV inverters, power loss, and increase in harmonics (THD, total distortion of AC output current) due to aging and deterioration due to long-term use. factors can be analyzed. Therefore, in this paper, the PV inverter operating characteristics according to the DC capacitor capacity state currently operating in the photovoltaic power generation system were considered, and research contents were proposed to secure the safety and reliability of renewable energy facilities.
