This research began by acknowledging that conventional analysis on the foreign exchange exposure could not adequately reflect firms’ risk management strategies, which firms take actions against uncertainties raised by foreign exchange. In order to conceptualize uncertainty aroused by foreign exchange, the purpose of this paper is to develop an index that could measure corporate profits’ sensitivity to foreign exchange uncertainty and examine its possibility of utilization.

As an alternative to foreign exchange exposure, the present research derived the foreign exchange volatility exposure and analyzed the determinants of foreign currency-denominated debt in terms of foreign exchange volatility exposure. The foreign exchange volatility exposure draws from partially differentiating a firm’s operating profits to the exchange rate volatility.

The major findings are as follows. First, before the Asian financial crisis, South Korean enterprises had similar responses to the exchange volatility exposure as compared with the exchange exposure on procuring foreign-denominated debt. Second, since the global financial crisis (GFC), not only have Korean firms’ response mechanisms to both exposures changed, but also the significance of exchange volatility exposure has been further emphasized. Furthermore, Korean companies have dealt with exchange uncertainties by decreasing foreign-denominated debt as their foreign exchange volatility exposure increased after GFC. In contrast, the influence of conventional exchange exposure on foreign-denominated debt has diminished.

Future research should focus on several points. First, additional research could extend to foreign investors who have divergent perception and consideration in regard to foreign exchange risk management. Second, research on decision making and motivation in foreign currency choice should be conducted in order to deepen academic understanding. Third, research that refines the variables added in the current research should be conducted. Finally, as a way to manage foreign exchange volatility exposure, further investigation based on this study is possible.

The results of this study have several important theoretical and empirical implications for companies’ foreign exchange risk management strategy. First, through foreign exchange volatility exposure, which can usefully take over the role of the existing foreign exchange exposure, the authors can confirm market uncertainty as being relevant to the foreign exchange risk management strategy. Second, through the financial influence that the foreign exchange volatility exposure has on the foreign currency-denominated debt, the authors can observe the Korean firms’ paradigm shifts in their foreign exchange risk management strategies.

This research confirms the importance of foreign exchange volatility exposure in the research works dealing with firms’ exchange risk management, also the possible influence of foreign exchange volatility exposure in the future might be increased as uncertainty is raised from foreign exchange escalating.

Despite children’s academic excellence in East Asian countries, school education in this region faces a range of challenges to build inclusive and quality education for all. This chapter aims at examining how these challenges occur and what actions have been taken to deal with them. By focusing on China, Japan, and the Republic of Korea, the chapter first reviews reforms of school education since the 1990s in these countries. The subsequent sections then present educational disparity and a new mode of teaching and learning in these countries. It concludes by addressing that East Asian countries must explore more common ground for building a more collective sense and identity to share responsibility for building a resilient, inclusive and sustainable world through global citizenship education and education for sustainable development.

With the prevailing use of online communication platforms, this study revisits the definitions of trust in an online context. By exploring organizational online communications from a practitioners' perspective, a conceptual framework that illustrates the nature of trust and its relationship with dialogic communication between organizations and organizations' stakeholders in the digital era is proposed.

A total of 27 in-depth interviews were conducted with public relations and marketing practitioners involved in coordinating organizational online communications in Hong Kong.

From the practitioners' perspective, stakeholders' online trust toward an organization, which is a hybridity of initial and rapidly evolving trust, begins with stakeholders swift and initial judgment of the organization according to category-based cues (including knowledge-based attributes of the organization, institutional cues, and particular attributes of online dialogic communication) available on online platforms and further develops over time. Practitioners regard the integration of online and offline communication platforms to be the most effective way to build trust in organization–stakeholder relationships in the digital era, while dialectical tensions can hinder trust formed in online communication.

Along with the proposed conceptual framework, this study advances the discussion of online trust in public relations practices from the practitioners' perspective. A qualitative approach provides rich descriptions that may help to enrich theories in public relations and communication management regarding the interplay of trust and dialogic communication in organizational practices in the digital era.

Wire + arc additive manufacturing (WAAM) uses existing welding technology to make a part from metal deposited in an almost net shape. WAAM is flexible in that it can use multiple materials successively or simultaneously during the manufacturing of a single component.

In this work, a gas metal arc welding (GMAW) based wire + arc additive manufacturing (WAAM) system has been developed to use two material successively and fabricate bimetallic additively manufactured structure (BAMS) of low carbon steel and AISI 316L stainless steel (SS).

The interface shows two distinctive zones of LCS and SS deposits without any weld defects. The hardness profile shows a sudden increase of hardness at the interface, which is attributed to the migration of chromium from the SS. The tensile test results show that the bimetallic specimens failed at the LCS side, as LCS has lower strength of the materials used.

The microstructural features and mechanical properties are studied in-depth with special emphasis on the bimetallic interface.

The purpose of this paper is to examine descriptive sensory characteristics and consumer acceptability of eight commercial ready-to-eat cooked rice samples by 8 trained panelists and 50 consumers.

A total of 24 descriptive attributes for appearance, odor/aroma, taste/flavor, and texture were developed. Also Consumer Acceptability (CA) was performed for overall liking, appearance, flavor, and texture liking. All statistical analyses were using analysis of variance, principal component analysis (PCA), hierarchical cluster analysis (HCA), and partial least square regression (PLSR).

The overall liking score for the cooked white rice from C brand was the highest (6.43) among the eight samples. Three groups of eight commercial ready-to-eat cooked rice samples were obtained from PCA and HCA. The samples of cooked white rice from C, N, and O brand characterized by intactness, starch odor, translucency, whiteness, and glossiness were located on to the positive PLS 1, whereas the samples of cooked white rice from D and E brand characterized by scorched odor, cohesiveness, stickiness, and moistness were located on the negative side of PLS 2 in the PLSR analysis.

Further studies on the improvement of sensory quality for brown rice are necessary to increase CA in terms of health functionality of brown rice.

In this age of extremely well-developed social media, it is necessary to detect any change in the corporate image of an enterprise immediately so as to take quick action to avoid the wide spread of a negative image. However, existing survey-based corporate image evaluation methods are costly, slow and static, and the results may quickly become outdated. User comments, news reports and we-media articles on the internet offer varied channels for enterprises to obtain public evaluations and feedback. The purpose of this study is to effectively use online information to timely and accurately measure enterprises’ corporate images.

A new corporate image evaluation method was built by first using a literature review to establish a corporate image evaluation index system. Next, an automatic text analysis of online public information was performed through a topic classification and sentiment analysis algorithm based on the dictionary. The accuracy of the topic classification and sentiment analysis algorithm is then calculated. Finally, three internet enterprises were chosen as cases, and their corporate image was evaluated.

The results show that the author’s corporate image evaluation method is effective.

First, in this study, a new corporate image evaluation index system is constructed. Second, a new corporate image evaluation method based on text mining is proposed that can support data-driven decision-making for managers with real-time corporate image evaluation results. Finally, this study improves the understanding of corporate image by generating business intelligence through online information. The findings provide researchers with specific and detailed suggestions that focus on the corporate image management of emerging internet enterprises.

This study aims to explore how educational leaders in South Korea adopted equity mindsets and how they organized changes to support students' deeper learning during COVID-19.

The authors developed a comprehensive framework of Equity Leadership for Deeper Learning, by revising the existing model of Darling-Hammond and Darling-Hammond (2022) and synthesizing equity leadership literature. Drawing upon this framework, this study analyzed data collected from individual interviews and a focus group with school and district administrators in the K-12 Korean education system.

The participants prioritized an equity stance of their leadership by critically understanding socio-political conditions, challenging unjust policies, and envisioning the big picture of equity-centered education. This led them to operationalize equity leadership in practice and create a more inclusive and supportive environment for student-centered deeper learning. District leaders established well-resourced systems by creating/developing instructional resources and making policies more useful. School leaders promoted quality teaching by strengthening access, developing student-centered curricula, and establishing individualized programs for more equitable deeper learning.

This study builds on scholarship of deeper learning and equity leadership by adding evidence from Korean educational leaders during COVID-19. First, the findings highlight the significance of leaders' equity mindsets in creating a safe and inclusive environment for deeper learning. This study further suggests that sharing an equity stance as a collective norm at the system level, spanning across districts and schools is important, which is instrumental to scale up innovation and reform initiatives. Second, this research also extends comparative, culturally informed perspectives to understand educational leadership. Most contemporary leadership theories originated from and are informed by Western and English-speaking contexts despite being widely applied to other contexts across the culture. This study's analysis underscores the importance of contextualizing leadership practices within the socio-historical contexts that influence how education systems are established and operate.

Leaders' adopting equity mindsets, utilizing bureaucratic resources in creative ways and implementing a school-wide quality curriculum are crucial to supporting students' deeper learning. District leaders can leverage existing vertical and horizontal networks to effectively communicate with teachers and local communities to establish well-recourced systems. As deeper learning is timeless and requires high levels of student engagement, school leaders' efforts to establish school-wide curricula is critical to facilitate deeper learning for students.

The study provides a nuanced understanding of how equity focused leaders responded to difficulties caused by the pandemic and strategized to support students' deeper learning. Existing studies tend to prioritize teacher effects on student learning, positing leadership effects as secondary or indirect. Alternatively, the authors argue that, without leadership supporting an inclusive environment, resourceful systems and student-centered school culture, deeper learning cannot be fully achieved in equitable ways.

After the Korean War, South Korean politics was dominated by national security concerns. Reversing Carl von Clausewitz's well-known dictum, in South Korea, “politics is the continuation of war by other means.” Until the late 1980s, politics in South Korea was far from democratic. South Korea had five direct presidential elections (1987, 1992, 1997, 2002, and 2007) and six national assembly elections (1988, 1992, 1996, 2000, 2004, and 2008) after the democratic transition of 1987. In 1992, a civilian candidate, Young Sam Kim, was elected president. Young Sam Kim (1993–1998) prosecuted and punished former generals turned presidents Doo Hwan Chun (1980–1988) and Tae Woo Roh (1988–1993) for corruption, mutiny and treason in 1995. Dae Jung Kim (1998–2003) was elected president in 1997. For the first time in South Korean political history, regime change occurred between a ruling party and an opposition party.

In this chapter, the change and continuity of civil–military relations through the fluctuating dynamics of the democratic transition and consolidation in South Korea is examined. A positive consolidation of democratic reform is one that, while securing indisputable civilian supremacy, grants the military enough institutional autonomy for the efficient pursuit of its mission. Civilian supremacy should be institutionalized not only by preventing military intervention in civilian politics but also by ensuring civilian control over the formation and implementation of national defense policy.

In sum, despite three terms of civilian presidency, civilian supremacy has not yet fully institutionalized. Although significant changes in civil-military relations did occur after the democratic transition, they were not initiated by elected leaders with the intention of establishing a firm institutional footing for civilian supremacy. South Korea's political leaders have not crafted durable regulations and institutions that will sustain civilian control over the military.

More than six decades, Korea is still divided. The most highly militarized zone in the world lies along the demilitarized zone. How to draw the line prudently between seeking national security and promoting democracy shall be the most delicate task facing all the civilian regimes to come in South Korea. That mission will remain challenging not only for civilian politicians but also for military leaders.

Utilizing affective event theory (AET), this paper aims to understand the affective reasoning behind choosing to speak up for or against abusive supervision. For this purpose, the authors examine the underlying mechanism of employee state paranoia in the relationship between abusive supervision and promotive and prohibitive voice of employees.

Data from 307 microfinance bank employees were collected using supervisor–subordinate nested design and time-lag approach. The analysis was performed through partial least square (PLS) structural equation modeling using Smart PLS software.

The results support the direct relationship of abusive supervision with promotive and prohibitive voice. They also support the mediating relation of paranoia arousal between abusive supervision and promotive voice. However, the results do not support the mediating relationship of paranoia arousal between abusive supervision and prohibitive voice.

In light of the literature drawn from AET and empirical data, this study forwards robust recommendations for theory and practice and may assist future researchers interested in the role of employee paranoia arousal.

Considering the importance of employees' voice behavior (VB) and psychological capital (PC) amidst the coronavirus disease 2019 (COVID-19), this study highlights the role of authentic leadership (AL) in building a psychologically strong workforce that can provide meaningful suggestions for the improvement of organization.

The study employed a questionnaire survey to collect the data and recruited 261 participants from the telecom sector Sindh, Pakistan. The data analysis was done using partial least squares structural equation modeling (PLS-SEM).

The findings of the study supported the hypotheses suggesting that AL can directly influence employees' VB and indirectly via PC.

The study was conducted during the COVID-19 in the telecom sector of Sindh, Pakistan. This study contributes by providing useful insights into that AL is an important form of leadership that encourages employees' voluntary behavior and psychological strength during the COVID-19 pandemic.
