Abstract
Purpose
The purpose of this paper is to examine the diversification effect of the Korean Ship Investment Fund (KSF) under Markowitz portfolio theory by analyzing short-term and long-term relationships with stocks and bonds.
Design/methodology/approach
For this purpose, unit root, correlation and cointegration tests are performed. Monthly data from 2004 to 2015 for stocks, bonds and KSFs are obtained for this study.
Findings
The correlation coefficients indicate that KSFs are uncorrelated with stocks and negatively correlated with bonds, and no long-term equilibrium relationships exist with all three variables by the Johansen and Engle-Granger cointegration tests.
Research limitations/implications
This paper makes contribution to the literature as follows: first, whereas the previous literature investigated diversification effect of ship investment using freight indices or freight rates which are not able to represent returns from ship investment, this study is the first study to use actual stock prices of the KSFs to the authors’ best knowledge; and second, diversification effect of ship investment represented by KSFs is empirically verified in the both short term and long term.
Practical implications
Policy-makers and managers of shipping companies can have sound ground that the KSFs are alternative and attractive assets to investors. It is also shown that the KSFs have potential to improve risk and return structure of investors on their own regardless of existence of incentives. Therefore, decisions of policy-makers can be made free from expectations for stronger incentives provided by the government. In addition, those countries that do not have such a ship investment platform may consider introducing a similar ship investment fund in order to revitalize the capital markets of the country.
Originality/value
This study holds its significance in investigating diversification properties of the KSFs for the first time in Korea since the KSFs were introduced.

Abstract
Purpose
The purpose of this study is to identify the attributes that statistically affect reason intention. The triple bottom line, a theoretical framework of corporate social responsibility (CSR) consisting of economic, social and environmental subdimensions, is used as the theoretical foundation.
Design/methodology/approach
In this study, price fairness, quarantine and hygiene, and eco-friendliness represent economic, social and environmental CSR, respectively. Amazon Mechanical Turk is used for data collection. The valid number of observations is 474. Structural equation modeling is implemented to test the research hypotheses.
Findings
The results indicate that price fairness, quarantine and hygiene positively affect the reuse intention of coffee shops. However, eco-friendliness appears to be an attribute that does not significantly affect reuse intention.
Originality/value
This study theoretically contributes to the literature by demonstrating the explanatory power of triple bottom line theory for café customer intention.

Abstract
Purpose
The purpose of this study is to identify and explore what leadership characteristics constitute humanistic leadership in the South Korean context. Moreover, this study examines how these leadership characteristics are connected to Korean culture.
Design/methodology/approach
Based on the information gathered from semi-structured interviews and other sources, including books, case study articles and news articles, this study captures a more comprehensive perspective of Mr. Kook-Hyun Moon, the former CEO of Yuhan–Kimberly.
Findings
The key characteristics of Mr. Moon's humanistic leadership that are identified in this study are: respect for all mankind, benevolence (seeking the greater good), sincerity (building trusting relationships with stakeholders) and continuous learning and innovation (developing self and others). These key characteristics set Mr. Moon apart from other leaders and are connected to the fundamental values and philosophies of Korean culture.
Originality/value
This study contributes to the current leadership literature by identifying and exploring Mr. Moon's humanistic leadership characteristics that enable him to gain respect and contribute to communities and society in the South Korean context. This study also finds that the humanistic leadership characteristics of Mr. Moon reflect three major attributes of Korean culture: the ideology of the Dangun mythology, the principle of Neo-Confucianism in Korea and jeong – an indigenous cultural concept in Korea (these attributes will be discussed in detail in the South Korean values and philosophies section). Such reflection suggests that investigating how humanistic leadership characteristics are connected to local cultural roots is important to enhance the understanding of humanistic leadership.

Abstract
Higher education institutions must keep up to date with the changing needs and situations of students, addressing societal issues affecting young people’s lives and learning. Among the crises that higher education institutions in South Korea are facing, population decline and a lack of sustainable development present a significant threat to these institutions’ existence as well as student satisfaction and learning experience. By relying on a review of relevant literature, this chapter will discuss each of these challenges and potential solutions. We hope that our discussion of the challenges in South Korea will also highlight that many of the ‘crises’ for higher education and ways to tackle them can be both localised and globally applicable. What is significant here is that higher education has a key role to play in preparing the young generation of Koreans to embrace sustainability and to foster resilience in them – for preparedness for future crises. We propose that a focus on community identity strength and education for sustainable development (ESD) can work as a solution for improving students’ learning and global citizenship in these areas. Furthermore, we argue that this is especially important for preserving local and regional strengths and, ultimately, mutual development between the region and universities. Sustainable development depends on building a stronger and positive personal and collective identity, and students’ active participation in sustainable development transcends the localised challenges. Such outcomes are also important for the sustainable future of higher education in South Korea and continuous development in the higher education scholarship.

Abstract
Purpose
This study explores food delivery app users and technology acceptance model as a theoretical underpinning. This study thus investigated the determinants of usefulness, ease of use and intention to use for food delivery app service.
Design/methodology/approach
The variables of delivery time, diverse menu, quarantine, review quality and ease of use are employed as determinants of usefulness. The antecedents of ease of use are easy registration and easy payment. This study also examined the association between ease of use, usefulness and intention to use. This study collected data using Amazon Mechanical Turk, and the number of valid observations for statistical analysis was 484. A structural equation model was used to test the hypotheses.
Findings
Regarding the results, usefulness was positively affected by delivery time, quarantine, review quality and ease of use. Additionally, ease of use was positively impacted by easy registration and easy payment. Finally, this study showed that ease of use positively affects both usefulness and intention to use, and usefulness is positively associated with intention to use.
Originality/value
This study contributes to the literature by ensuring the explanatory power of technology acceptance model for food delivery app.

Abstract
Purpose
This study aims to explore the structural relationship among food quality, usefulness, ease of use, convenience, brand trust and willingness to pay. The technology acceptance model was used as the theoretical foundation of this work.
Design/methodology/approach
Amazon Mechanical Turk was used to recruit survey participants, and 436 valid observations were ultimately used for the analysis. In the data analysis, the structural relationships between variables were explored through structural equation modeling.
Findings
The results of hypothesis testing show that ease of use positively affects the usefulness of the Starbucks mobile application. Usefulness also exerts positive impacts on both brand trust and convenience. Moreover, brand trust is positively associated with food quality. Finally, willingness to pay is positively influenced by both convenience and brand trust.
Originality/value
This study contributes to the literature by not only validating the technology acceptance model using the Starbucks mobile application but also proposing food quality-related attributes in the domain of the café business.
