Abstract
Purpose
The purpose of this paper is to present the development of an optimal design framework for high altitude long endurance solar unmanned aerial vehicle. The proposed solar aircraft design framework provides a simple method to design solar aircraft for users of all levels of experience.
Design/methodology/approach
This design framework consists of algorithms and user interfaces for the design of experiments, optimization and mission analysis that includes aerodynamics, performance, solar energy, weight and flight distances.
Findings
The proposed sizing method produces the optimal solar aircraft that yields the minimum weight and satisfies the constraints such as the power balance, the night time energy balance and the lift coefficient limit.
Research limitations/implications
The design conditions for the sizing process are given in terms of mission altitudes, flight dates, flight latitudes/longitudes and design factors for the aircraft configuration.
Practical implications
The framework environment is light and easily accessible as it is implemented using open programs without the use of any expensive commercial tools or in-house programs. In addition, this study presents a sizing method for solar aircraft as traditional sizing methods fail to reflect their unique features.
Social implications
Solar aircraft can be used in place of a satellite and introduce many advantages. The solar aircraft is much cheaper than the conventional satellite, which costs approximately $200-300m. It operates at a closer altitude to the ground and allows for a better visual inspection. It also provides greater flexibility of missions and covers a wider range of applications.
Originality/value
This study presents the implementation of a function that yields optimized flight performance under the given mission conditions, such as climb, cruise and descent for a solar aircraft.

Abstract
Purpose
The purpose of this paper is to analyze the policy trends for the internationalization of higher education in Korea, and suggest a future direction toward the pursuit of Sustainable Development Goals (SDGs).
Design/methodology/approach
This paper presents a case study of Korea focusing on its internationalization in higher education. In order to analyze the government policy trends and institutional strategies for internationalization, the relevant literature and documents were analyzed.
Findings
The government policy for the internationalization of higher education in Korea has consisted of three stages: first, controlled outbound mobility; second, a major shift and focus on inbound mobility, recently along with intraregional cooperation for both directions of mobility in Asia and third, the beginning of efforts toward the pursuit of the SDGs, which needs to be expanded and systematized further.
Originality/value
This paper shows presents the comprehensive review of internationalization policies in Korean higher education, including the recent programs and changes at both the governmental and institutional levels. There has been a notable lack of discussion on the SDGs in relation to the internationalization of Korean higher education, which is addressed in this paper.

Abstract
The real costs of trade, the transport and other costs of doing business internationally, are very important determinants of a country's ability to participate fully in the world economy. Remoteness and poor transport and communications infrastructure isolate countries, inhibiting their participation in global production networks. This paper investigates the dependence of transport costs on geography and infrastructure It shows that infrastructure is quantitatively important in determining transport costs, and improvements in infrastructure can dramatically increase trade flows. It also finds that the low level of Northeast Asian countries' trade flows is largely due to poor infrastructure. Competition among countries in East Asia to maintain or become a logistic hub in the region is severe. This is reflected in the competition to build or expand airports and seaports in the region. Competing countries need to find ways of cooperating to achieve an efficient resource allocation in the region as a whole.

Abstract
This chapter provides a theory model of trade finance to explain the “great trade collapse.” The model shows that, first, the riskiness of international transactions rises relative to domestic transactions during economic downturns; and second, the exclusive use of a letter of credit in international transactions exacerbates a collapse in trade during a financial crisis. The basic model considers banks’ optimal screening decisions in the presence of counterparty default risks. In equilibrium, banks will maintain a higher precision screening test for domestic firms and a lower precision screening test for foreign firms, which constitutes the main mechanism of the model.

Abstract
Purpose
This paper aims to improve customer knowledge management practices in industrial firms by examining the role of knowledge integration mechanisms (KIMs) and customer-oriented reward systems in non-marketing managers’ use of customer information.
Design/methodology/approach
Cross-sectional survey data were collected from 221 R & D and manufacturing managers from large, Finnish industrial companies. Ordinary least squares regression with bootstrap procedures was used to test the hypotheses.
Findings
The use of KIMs mediates the positive effect of customer-oriented reward systems on non-marketing managers’ use of customer information. However, non-marketing managers’ previous work experience in sales and marketing negatively moderates the effect of customer-oriented reward systems on the use of customer information. The use of knowledge integration systems mediates this moderation effect.
Research limitations/implications
This paper provides empirical evidence concerning the antecedents of successful customer knowledge transfer from sales and marketing to R & D and manufacturing. The findings imply that non-marketing managers with T-shaped skills (previous work experience also in sales and marketing) are unlikely to increase their use of KIMs if they are exposed to customer-oriented reward systems. Hence, broadening employees’ knowledge base substitutes for using customer-oriented reward systems as a tool for improving customer information use.
Originality/value
Building on the research on customer knowledge management, marketing’s cross-functional relationships and the motivation for knowledge transfer, this paper increases our understanding of how to develop organizational support for customer knowledge transfer. The authors consider both the impact of reward systems and their interaction with employees’ knowledge and skills.

Abstract
Purpose
This paper contributes to leadership categorization theory by advocating a new method to surface people's implicit leadership theories. The purpose of this new approach is to simultaneously capture individual difference in how they conceptualize leadership but within a common framework to allow for comparison of within- and between-person effects.
Design/methodology/approach
The authors conduct a narrative review of the implicit leadership theory, leadership categorization theory, cognitive mapping and verbal protocol literature with the purpose of surfacing a research method that will overcome the problems of over-simplification and over-individualization in existing methods.
Findings
The authors argue that using a combination of cognitive mapping and verbal protocols can capture the idiosyncrasies of individual lay theories of leadership while retaining the ability to compare people's responses through a common framework. The authors provide an example of how this method can be used to elicit people's perceptions of one aspect of implicit leadership theories, intelligence.
Research limitations/implications
This new method will provide a methodology to test the subset propositions advocated by leadership categorization theory. These include the idea that subordinate level implicit leadership theories contain a subset of attributes found in the basic-level implicit leadership theories, that there is attribute integrity in superordinate implicit leadership theories through the levels, and the idea that people define leadership differently depending on the context they are observing.
Originality/value
Whereas previous approaches to surfacing people's implicit leadership theories either heavily constrain their responses with a predetermined generic suite of attributes or are totally open-ended and idiosyncratic, the authors advocate an approach that combines the best of both.

Abstract
Purpose
The purpose of this paper is to explain why Singapore has succeeded in curbing corruption and to recommend three measures for enhancing South Korea’s anti-corruption strategy.
Design/methodology/approach
The paper compares the contextual differences between Singapore and South Korea before analysing Singapore’s effective anti-corruption strategy and identifying the weaknesses of South Korea’s anti-corruption strategy.
Findings
Singapore’s success in minimising corruption is the result of its government’s strong political will and the adequate budget, personnel and operational autonomy given to the Corrupt Practices Investigation Bureau to enable it to enforce the anti-corruption laws impartially. To improve South Korea’s anti-corruption strategy, the Korea Anti-Corruption Agency should be established and adequately staffed and funded to investigate corruption cases. Those found guilty of corruption offences should be punished according to the law, without suspending their jail sentences or being pardoned by the president. Finally, the existing public outreach anti-corruption programmes should be evaluated to identify their weaknesses and improve their effectiveness.
Originality/value
This paper recommends three measures for South Korean policy-makers to improve their anti-corruption strategy by learning from Singapore’s success.

Abstract
Corruption was a serious problem in Singapore during the British colonial period and especially after the Japanese Occupation (February 1942–August 1945) mainly because of the lack of political will to curb it by the incumbent governments. In contrast, the People’s Action Party (PAP) government, which assumed office in June 1959 after winning the May 1959 general election, demonstrated its political will with the enactment of the Prevention of Corruption Act (POCA) in June 1960, which strengthened the capacity of the Corrupt Practices Investigation Bureau (CPIB) to combat corruption effectively. Indeed, Singapore’s success in curbing corruption is reflected in its consistently high scores on Transparency International’s Corruption Perceptions Index (CPI) from 1995 to 2012 as the least corrupt country in Asia. Singapore was ranked first with Denmark and New Zealand in the 2010 CPI with a score of 9.30. Similarly, Singapore has been ranked first in the Political and Economic Risk Consultancy (PERC) annual surveys on corruption from 1995 to 2013. Why has Singapore succeeded in minimizing the problem of corruption when many other Asian countries have failed to do so? What lessons can these countries learn from Singapore’s experience in combating corruption? This chapter addresses these two questions by first describing Singapore’s favorable policy context, followed by an identification of the major causes of corruption during the British colonial period and Japanese Occupation, and an evaluation of the PAP government’s anti-corruption strategy.

Abstract
Purpose
This paper aims to explore the opportunities of integrating internet of things (IoT) with building information modelling (BIM) to support the digital transformation of facilities management (FM). In this regard, a conceptual framework is proposed to implement IoT-BIM-based smart FM in buildings.
Design/methodology/approach
A semi-systematic literature review was conducted to examine the opportunities of integrating IoT-BIM-based smart FM.
Findings
BIM models are seldom used during the operations stage, and the comprehensive digital information developed during the design and construction stage is not efficiently used throughout the building’s life cycle. Therefore, this paper suggests that IoT-BIM can be effectively integrated into six FM functions, namely, energy management, operations and maintenance management, space management, FM project management, emergency management and quality management. IoT-BIM provides a beneficial platform for the digital transformation in FM, optimising the effectiveness and efficiency of buildings.
Originality/value
As a recent approach, the integration of BIM with IoT has created a new direction for moving from traditional FM to digitalise smart FM. However, the adaptation of IoT-BIM concept, particularly for FM, is yet to be explored. Hence, this paper contributes to the IoT-BIM research in the FM domain by highlighting six IoT-BIM-based smart FM for digital transformation in FM.

Abstract
Purpose
Health-related online fake news (HOFN) has become a major social problem. HOFN can lead to the spread of ineffective and even harmful remedies. The study aims to understand Internet users' responses to HOFN during the coronavirus (COVID-19) pandemic using the protective action decision model (PADM).
Design/methodology/approach
The authors collected pandemic severity data (regional number of confirmed cases) from government websites of the USA and China (Studies 1 and 2), search behavior from Google and Baidu search engines (Studies 1 and 2) and data regarding trust in two online fake news stories from two national surveys (Studies 2 and 3). All data were analyzed using a multi-level linear model.
Findings
The research detected negative time-lagged relationships between pandemic severity and regional HOFN search behavior by three actual fake news stories from the USA and China (Study 1). Importantly, trust in HOFN served as a mediator in the time-lagged relationship between pandemic severity and search behavior (Study 2). Additionally, the relationship between pandemic severity and trust in HOFN varied according to individuals' perceived control (Study 3).
Originality/value
The authors' results underscore the important role of PADM in understanding Internet users' trust in and search for HOFN. When people trust HOFN, they may seek more information to implement further protective actions. Importantly, it appears that trust in HOFN varies with environmental cues (regional pandemic severity) and with individuals' perceived control, providing insight into developing coping strategies during a pandemic.
