Abstract

ELS (Equity Linked Security) is the structured product which is one of the fast grown and the most successful in Korean financial markets. In particular, ELS with the index of stocks as underlying asset (‘index ELS') has shown a remarkable growth since 2010. This paper has analyzed the hedging effects of index ELS to the KOSPI200 index and futures market. It verifies that the hedging of index ELS has not shown any significant effect to the return of KOSPI200 index and futures, but it seems that it effects on the volatility. In other words, as ELS issue amount increases, VKOSPI tends to decrease because ELS issuer which has long vega position is trying to hedge it.

Abstract

Korea is a highly centralized country where most administrative functions are carried out by the central government in Seoul. Increasingly, however, local governments have been given greater autonomy in their operations. This chapter examines how the ideal values of political decentralization have interacted with the country’s local bureaucracy, which inherently has dark side in itself. The focus is on how local government employees have contributed, or responded, to the democratic change of their communities, particularly since the 1980s. At the outset, the experiences of Korea’s decentralization and local autonomy are briefly reviewed. It is then examined how the bureaucrats have played in the process of democratization in terms of three features: bureaucratic power, scope, and culture. Institutionalizing competitive local bureaucracy contributed to reduce the disparity between capital regions (Seoul and its surrounded area) and noncapital regions (locals). Empowering local bureaucracy to allow own localized decision-making process was the first move of Korean governance.

Abstract

Purpose

The purpose of this paper is to systematically review the functionalities, safety regulations and product applications of herb Stevia rebaudiana extract. This plant material is embedded with multiple functionalities such as antioxidant, antidiabetics, anti-inflammation and antimicrobial. The regulations released from global authorities are covered to ensure the safety premise of stevia. Besides, the product applications of the extract of aerial parts of the herb S. rebaudiana helps us to recognize its value from commercial side.

Design/methodology/approach

Relevant literatures are selected and obtained from main scientific databases such as Google Scholar, Web of Science, PubMed and trade magazines published between 2000 and 2023. The keywords and their possible combinations such as sweetening, antioxidant, antidiabetics, anti-inflammation, safety and product development were used to ensure the preciseness and completeness of literature searching. Major data such as sweetness, total phenolic content and dose together with latter critical conclusions from searched publications were appropriately used and discussed. In this review, approximately 150 scientific literatures were meticulously ordered and analyzed. In applications, it is the first time that sentiment analysis was used to obtain a market assessment of the stevia-containing products.

Findings

This review paper helps rearrange the scientific affairs of those stevia extract’s functions like sweetening, antioxidant, antidiabetics and inflammation. Sweetness indexes of steviol glycosides were summarized together for comparison while various in vitro and in vivo approaches were reviewed to quantify those functions’ capacities and to depict the related mechanism. The regulation of steviol glycoside compounds such as rebaudioside A was established by global authorities such as US Food and Drug Administration and Joint FAO/World Health Organization Expert Committee to ensure the safety endorsement before commercialization. Then, this study discussed about the market performance of stevia ingredients or products with the self-developed data analytics. This study also investigated the product development progress of stevia-containing food products in the categories of beverage, bakery, dairy and confectionery. Those stevia-containing food consumer goods can be acceptable by certain consumers.

Originality/value

This review paper precisely presents the evidential information about the stevia’s multiple functionalities with mechanisms and global regulation milestones. To the best of the authors’ knowledge, it is then the first time to probe the stevia-containing products’ market performance through data analytics.

Abstract

Purpose

The purpose of this paper is to provide a network analysis of Twitter discussions about Myung-Bak Lee, a former president of South Korea, to gain a better understanding of the dynamics of the public opinion exchange on Twitter.

Design/methodology/approach

Opinion leaders in the discussion network were identified by considering the longitudinal distribution of tweets containing the former president’s name, and three types of messages (“followings,” “mentions,” and “retweets”) were analyzed using data collected from November 1, 2011, to April 20, 2012. The sample included 26,150 Twitter users and 892,034 relationships reflecting three types of messages.

Findings

The results indicate that the discussion about President Myung-Bak Lee was dominated by liberal Twitter users who already had considerable influence both online and offline. In addition, Twitter users were unlikely to interact with other users with opposing political views.

Research limitations/implications

Almost all of the opinion leaders identified in the study held liberal political views, and liberal Twitter users dominated the discussion network. In addition, the Korean Twitter network showed the presence of the homophily phenomenon, implying that opinion leaders’ influence within the Twitter network was limited to other users sharing the same political views. Further, political views of opinion leaders were skewed toward a particular political stance without necessarily representing the opinion of the general public, possibly hindering the democratic process.

Originality/value

This study tests the homophily thesis in the context of Twitter users in Korea and contributes to the literature on Twitter-based political discourse by identifying opinion leaders in Korean Twitter networks and examining the phenomenon of homophily within those networks.

Abstract

Purpose

This study explores the enablers of students “entrepreneurial intentions by identifying the factors that raise students” interest in embracing an entrepreneurial career.

Design/methodology/approach

Entrepreneurship education is increasingly attracting attention as a means of fostering entrepreneurial activity and creating a culture of innovation. Developing students' entrepreneurial intentions is critical to promote entrepreneurship. This research is built on a mixed method approach of partial least squares structural equation modelling and fuzzy-set qualitative comparative analysis.

Findings

The factors that influence students ‘entrepreneurial intentions are identified: business incubation programmes, non-reimbursable grants for entrepreneurial students, networking events to promote entrepreneurship, mentoring services, innovation labs for business idea validation and entrepreneurship courses. This knowledge can help develop effective entrepreneurship education programmes. The study also provides actionable insights for educational institutions and policymakers. It underscores the need for innovative educational platforms such as entrepreneurial bootcamps. It also highlights the value of advanced learning environments such as decision theatres to foster a culture of entrepreneurship and innovation.

Originality/value

The study contributes to the body of knowledge on entrepreneurship education. It highlights the need for a multidisciplinary approach to understand the factors that shape students’ entrepreneurial intentions.
