The purpose of this study was to develop a music teacher training program for global citizenship education and explore its effects on the participants' capacity for global citizenship. The program focused on multicultural education, including diversity and tolerance, among various topics in global citizenship education and consisted of practice to develop lesson plans for middle school music classes as well as theory about music in diverse sociocultural environments. The results showed that this program positively affected the participants' attitudes about a music teacher's role in the multicultural classroom. This program enabled participants to identify and reflect on any prejudice they may have against diversity and multiculturalism and to consider the role of music teachers in multicultural learning environments. The program also helped the participants develop greater self-efficacy as music teachers in multicultural environments and see music as a symbolic expression and a social and cultural product. Finally, the participants showed their positive attitude toward transformative pedagogy and considered various topics in global citizenship education beyond diversity and multiculturalism through multilateral understanding and exploration about music based on theory and practice in global citizenship education.

The study aims to synthesize the discussion of the innovation district and suggest an alternative to the governance system of the innovation district. Cluster policies that focus on industrial specialization, networking, value chains, and industrial ecosystems have shown some problems and limits in advanced industrial economies. The innovation district, suitable for the era of urban innovation, convergence of industry, housing, leisure, and related variety, emphasizes cooperation through the convergence of various innovations, workshops and industries, and communities. It is important to build a quintuple helix based on cooperative governance through public-private partnerships, integrate the physical and cultural atmosphere, and service industries that strengthen the place prestige. Beyond the industrial aspect, innovation districts can facilitate changes in urban amenities and lifestyles and creative atmosphere, such as diversity, lifestyle, charms, and openness, and promote social vitality and economic interactions. The governance of innovative districts can promote inter-organizational exchanges, and combinations. When knowledge is created through exchanges between companies, it also affects changes in the governance system, evolving from a rigid and centralized system to an open, dynamic, and organic system. Through the innovation policy, the existing Central Business Districts (CBD) can be able to be transformed into a Central Lifestyle Districts (CLD).

This study was done to develop indicators for cities that can be used in the long term and in a sustainable manner. Activation indicators were developed to improve the resilience in the downtown area of Seo-gu, Incheon. Preliminary indicators were derived from prior studies on similar indicators of resilience for urban regeneration, and an expert opinion survey was conducted to analyze the suitability and importance of the indicators. Activation indicators were established for improving urban resilience in six areas: population stability, social inclusion, industrial diversity, local productivity, environmental sustainability, and social-based convenience. From 60 preliminary indicators, 42 indicators were selected through the expert opinion surveys for securing an economically active population, establishing a living infrastructure, improving the settlement environment, and upgrading industry to reflect the characteristics of the West, including industrial complexes. It was found that diversification is necessary. Further study is still necessary to improve the objectivity of the indicators and calculate a resilience index. The significance of this study is that it looks at quantitative indicators, complements other studies on regional decline diagnosis, and presents realistic alternatives suitable for domestic situations based on the concept of resilience.

The paper considers a hybrid model to analyze and forecast time series data based on an empirical mode decomposition (EMD) that accommodates complex characteristics of time series such as nonstationarity and nonlinearity. We aggregate IMFs using the concept of cumulative energy to improve the interpretability of intrinsic mode functions (IMFs) from EMD. We forecast aggregated IMFs and residue with a hybrid model that combines the ARIMA model and an exponential smoothing method (ETS). The proposed method is applied to forecast KOSPI time series and is compared to traditional forecast models. Aggregated IMFs and residue provide a convenience to interpret the short, medium and long term dynamics of the KOSPI. It is also observed that the hybrid model with ARIMA and ETS is superior to traditional and other types of hybrid models.

After making amendments to archive-related legislations in 2006, the Electronic Records Management Systems (ERMS) were introduced into public institutions. With this, most institutions constructed digital repositories in their records center. In this system, there are several weaknesses that wasted costs and manpower for its introduction and maintenance. The extensibility of a repository is debased, and securing the interoperability is difficult. The study proposed a cloud computing-based model to solve such problems that the previous system had. In particular, this study expected effects through the proposed model. The expected effects are low-cost, highly efficient, extensible, and interoperable in embracing various systems. Thus, the appropriateness of introducing cloud computing into ERMS was analyzed in this study.

As the untact culture spreads, the digital divide, which is a problem of access to digital information for the vulnerable, can appear as information inequality in various fields, including the social and cultural field. This study identified the digital divide level for the vulnerable population and analyzed the effects of information accessibility, demographic and social characteristics, and physical and mental health characteristics on the information level. As a result, the higher the accessibility of information, the smaller the digital divide and the greater the digital utilization, so it is necessary to increase the accessibility of information devices and increase the ability to utilize them. In addition, the higher the age, the more women than men, and the lower the income level, the greater the digital divide, so it is necessary to increase digital capabilities through detailed class-specific programs for the vulnerable. Finally, it was found that the digital divide and the level of digital literacy had a significant effect on the life satisfaction and daily life satisfaction of the vulnerable. The expansion of competency-building education programs to enhance information utilization capabilities by changing the paradigm to a digital inclusion policy should be continuously operated.

It is commonly emphasized that the metaphor of the monster is a rhetoric universally used to identify the "main enemy" of a society, for its effective function is seen as useful for the uniting of citizens to bend together to survive or succeed before the external threat. The problem of this metaphor is that it homogenizes and dehumanizes the heterogeneous individual members of the subsequently identified enemy group. This study emphasizes the importance of some traits of the posthuman subject, such as the flexibility and the multiplicity of consciousness, to overcome the otherizing binary perspective which is commonly held regarding the concepts of good and evil. To observe specific dimensions of the posthuman consciousness, we analyze three films based on Spanish history and reality: The Spirit of the Beehive, The Day of the Beast and Pan's Labyrinth. All of these films progress around the figure of the enemy-monster(s), showing how to transgress the dichotomous structure of consciousness that defines the self/good dividing it from the other/evil. The heroes in the films seek to overcome the fear about the monster, and approach him to discover new ethical horizons, that can emerge only when an individual's consciousness chooses to stay on the border between the established beliefs and the unfamiliar voice of the dangerous stranger(s).

Digital citizenship includes an evolving set of knowledge and skills related to effectively and ethically using technology, especially when interacting with other people, information, and media in the online context. As public libraries have long provided access to and training with a variety of technologies, this study explores how digital citizenship has been covered in public library programming to identify potential trends and best practices. A purposive sampling of public library recipients of the American Library Association (ALA) and Information Today Inc.'s Library of the Future Award over the past 11 years (2013-2023) identified 7 case libraries to review. The titles and descriptions of 337 relevant library programs for audiences of school-aged children (5 years old and up) to seniors were collected for a 2-month period from each library's website and analyzed using Ribble & Parks (2019) 9 elements of digital citizenship. The findings suggest that programming related to digital citizenship most often addresses themes connected to digital access and digital fluency through coverage of topics related to computer and technology use. Based on themes and examples from the findings, public libraries are encouraged to expand upon existing programs to integrate all elements of digital citizenship, strive for inclusive and accessible digital citizenship education for all ages, and leverage resources and expertise from relevant stakeholders and community partnerships.
