This paper is a study to analyze when ISV(independent software company) has more active participation in the platform ecosystem. According to previous studies, companies are active in technological innovation when they can appropriate the outcome of innovation and when they have complementary assets (marketing, manufacturing capabilities, etc.) that can convert the innovation into value. The effect of these two conditions to join platform ecosystem is investigated. The duplication between the ISV's product portfolio and platform service is also included as an independent variable. The two sample groups are composed of independent SW companies that signed a partner agreement with platform companies and non-participating companies in the platform. As a result of empirical study, it is found that the patent rights do not affect participation in the platform. The ISVs might have believed that the benefits from cooperation with platform companies are greater than the risks of exposure to innovative technologies and unique Biz models. On the other hand, downstream's capability and the duplication of product portfolio affect participation in the platform. If ISVs have the downstream capability to transform cooperation into value creation, ISVs are actively participating in the platform. In addition, cooperation is active when the product portfolio is complementary to platform service rather than competition. This study is the empirical study of open innovation between Korean independent software companies and digital platform companies. There are similar prior studies abroad, but there are no similar studies in Korea. It is meaningful in that the determinants of platform ecosystem participation were investigated through empirical analysis by composing a sample group of companies participating in the platform ecosystem and companies not participating in the platform ecosystem.

Condition assessment of analog records is enforced to establish a preservation strategy and identify the damaged records by the Public Records Management Act and the public standard in Korea. However, the number of record management organizations where the condition assessment according to the act and the standard are actually conducted is limited in Korea. To find out what to change in the system and the practice of the condition assessment, the system and situation on the condition assessment of the paper-based records in Korea and other countries were investigated through literature research and a survey. Whereas Korean archives try to assess entire individual records, archives and libraries overseas apply condition assessment selectively depending on not only historical and cultural values of the records but also the vulnerability of compositional materials and severity of the damage of the records. It seems that archives and libraries overseas have a specific reason to conduct the assessment. Most of them take advantage of a sampling method not assessing every single item. Moreover, the periodical assessment is carried out in only about 50% of the responses. Therefore, we have to consider changing our condition assessment system to a more efficient and flexible way, adopting a sampling method and applying the assessment for selective collections with more specific purposes.

This paper establishes and propagates the value of the play through the study of the transition process of the yesan play from 1920 to the present, presents an alternative through the unique theatricality of the region and aims to activate it. The theater divided the theater into Yecheon, Chungnam Theater Festival, and Youth Theater Festival, which are currently active, and focused on Yedang International Performing Arts Festival, which is the only one in Yesan. The details of the performance due to the loss of data were not specified as much as possible, but the contents of the yesan play before 1990 were reviewed using the eupji and Myeonji. It also starts with a lack of diversity in plays in the developing direction of Yesan. Children's plays should be dismissed for simple commercial purposes, or the value of traditional Korean plays should be compared to Western ones, to promote the development of local plays through the natural characteristics and the basis of traditional culture, and to sustain the continuity of extreme economic performance and performances through the development of repertoires. Infrastructure deployment can be cited. The in flow of specialized actors and the use of art administrators creates a stable theater environment and activates the reeducation of local actors to promote theatrical imagination. It is also an urgent task to develop a new theatrical form by introducing experimental theatrical methods of young artists in the overseas performance business of theater troupe Yechon. Finally, Yedang International Performing Arts Festival should be characterized and differentiated from other festivals.

This paper introduces Youngju Ryu's Writers of the Winter Republic: Literature and Resistance in Park Chung Hee's Korea, and examines its significance and limitations. The book examines the relationship between literature and politics during the Park Chung-hee Yushin era, focusing on Yang Sŏng-u, Kim Chi-ha, Yi Mun-gu, Cho Se-hŭi, and Hwang Sok-yong. The books starts by describing the relationship between the U.S. hegemony and the Park Chung-hee regime during the Cold War. The book shows how poets like Yang and Kim fought against the Park Chung-hee regime based on poems, trial records and memoirs, while it describes novelists such as Yi's resistance by how novels envisioned a community against the Park administration based on the keyword "neighborhood." This is significant in that it describes how literature from the Park Chung-hee era was able to stand on the front lines against the regime. However, it is regrettable that because the book adopts a heroic tale to describe their lives and literature, these are illuminated in a somewhat flat way. Also it is noteworthy that the lives and works of novelists after the 2000s were illuminated, but Yang and Kim's life and literature were not described. Furthermore, it is regrettable that women writers were not mentioned and its concept of "politics" is rather shallow. Overall, this book is very significant in that it introduces the relationship between Korean literature and politics in the Korea of the 1970s with rich data and a beautiful style, as well as allowing Korean studies researchers to reflect on the future of Korean studies.

This study is about the development and creation of the public installation to enhance the contact chances with plants for the city dwellers who are living in the environment of limited green space. The researcher tried to create a floral art work at an island type bus stop on the central bus only lane, where the passers-by can enjoy the contact with plants for a second on that crowded space. The researcher made the study of various related cased world-widely and existing island type bus stop on the central bus only lane. The researcher also made pre-creation study of applicable forms and elements, and developed the prototype of the installation on the base of that study. Therefore the researcher created 1 installable screen type floral art work offering abundant contact experience to the viewers which has multiple shelves in the vertical frame to fit and be substituted by the designated wall unit of the island type bus stop structure. Also the researcher developed the prototypes of 2 small interior pieces. The meaning of this study can be found in the contribution of increasing visual experiencing rate of green space and chances of experiencing plants to create positive psychological, emotional effects by developing floral art works to be installed at crowded urban public space.

The air travel industry, which had shrunk with COVID-19, is gaining wings again. Accordingly, this study investigated whether non-verbal communication factors experienced through interaction with airline flight attendants for passengers who have traveled abroad within the past year through domestic airlines affect customer engagement and brand intimacy. A total of 285 samples were collected, and SPSS 28 and AMOS 26 programs were used to verify the reliability and validity of the research tool, the suitability of the model, and hypotheses. As a result of the empirical study analysis, it was confirmed that Paralanguage and Proxemics in non-verbal communication of flight attendants had a significant effect on customer engagement. Although it is different from the results of previous studies following changes in perspective after COVID-19, it once again confirmed the importance of airline crew communication in providing face-to-face services at the interface with passengers. In order to induce customer engagement, which is a new customer satisfaction management index. In addition, it was confirmed that customer engagement has a significant effect on brand intimacy. These results support the view that it is necessary to establish new customer management indicators of emotion and relationship marketing in the existing marketing centered on price reduction or securing loyalty. It was confirmed that interactions with flight attendants can contribute to customer engagement, and these results have important implications for those working in the air transportation industry.

Since tunnels are built underground, it is impossible to check visually the location and degree of deterioration of steel ribs. Therefore, in tunnel maintenance, GPR images are generally used to detect steel ribs. While research on GPR image analysis employing artificial neural networks has primarily focused on detecting underground pipes and road damage, there have been limited applications for analyzing tunnel GPR data, specifically for steel rib detection, both internationally and domestically. In this study, a one-step object detection algorithm called YOLO, based on a convolutional neural network, was utilized to automate the localization of steel ribs using GPR data. The performance of the algorithm is then analyzed. Two datasets were employed for the analysis. A dataset comprising 512 original images and another dataset consisting of 2,048 augmented images. The omission rate, which represents the ratio of undetected steel ribs to the total number of steel ribs, was 0.38% for the model using the augmented data, whereas the omission rate for the model using only the original data was 7.18%. Thus, from an automation standpoint, it is more practical to employ an augmented dataset.

Children's films can be found by country and region within the scope of world films, but children's films have different definitions depending on the country and region. For example, American children's films represented by Disney are mainly aimed at satisfying the joys of children and families.Chinese children's films place more importance on the educational role of children. Although the purpose is different, children's films in the general sense are films that main audiences are children and are created for children. Children's films in Iran differ greatly from ordinary children's films. It indirectly expresses the creator's intention by reflecting reality while looking at the adult world through the eyes of children. This special function is a children's visual language that indirectly conveys the creator's thoughts. The use of children's perspective is a kind of special strategy, paving the way for Iranian films to survive in a special creative environment, and creating unique characteristics of Iranian films. Among the numerous Iranian directors who make children's films, Majid Majidi is one of the representative directors with personal characteristics. Of his nine Iranian films written and directed, five are children's films.At the same time, in his other Iranian films, we can more or less see the traces of children and children's perspective of the narrative and performance.Looking at the use of children's vision in Iranian films, the use of children's vision in Iranian films began with children's films and developed in Iranian children's films and other genres of Iranian films.

Recently, the city railway in the Seoul Metropolitan Area (SMA) has offered a low quality of service as a passage time, because it was operated slowly. So, the people who live in modern society are not satisfied about passage time, therefore, this study tried to make that the subway in the SMA becomes a more functional and effective wide-area-transportation-network through an express train introduction's method which examined cases from abroad and current system. and then presented how express train could be applied to current system. In a case study, We used the An-San Line and Su-In Line as a examples and developed a schedule which can minimize the delaying time of subway by using Branch & Bound Algorithm. The train operational plan was loaded to consider a railroad siding, Obtained site, and the dispatch interval(three to ten minutes) for the express and local lines and finally, We presented an alternative operational plan which made by those factors.
