Abstract
Business process re‐engineering is a hot topic around management and information systems areas. However, the verdict of the new idea is not clear and reports of successful cases are not numerous. Analyses the definitions and characteristics of business process re‐engineering (BPR). Reports on a literature survey on the critical failure reasons and success factors. Recognizes that the lack of clear concepts and understanding of BPR definitions creates many problems and, therefore, compares the BPR effort with other improvement programmes such as automation, downsizing, total quality management (TQM) for a better understanding of BPR. Suggests a methodology which can be used as general guidelines for management and re‐engineers in performing BPR to enhance success for BPR efforts.

Abstract
Purpose
The purpose of this paper is to investigate surroundings for transfer film formation and removal, the effect of the transfer film formation on friction coefficients, the effect of four different abrasive components, ZrO2, ZrSiO4, Al2O3 and Fe3O4, on transfer film formation and the effect of lubricating component MoS2 on transfer film formation and friction coefficients.
Design/methodology/approach
Two different MoS2 contents of 5.5 and 8.5 per cent were added to friction materials with no MoS2 content, which have four different abrasive components, ZrO2, ZrSiO4, Al2O3, Fe3O4. Friction tests composed of three different stages were conducted for those materials, and the friction surfaces of the counterpart disks were examined by scanning electron microscopy (SEM) to access the formation of transfer film at each stage.
Findings
For the transfer film formation, high temperature was a prerequisite, but the magnitude of deceleration rate was not important. The effect of the transfer film formation was to reduce the friction coefficients for most friction materials. Friction coefficients of materials which contain lubricating component MoS2 were higher than those which contain no MoS2 for most friction materials. The effect of the lubricating component MoS2 was to suppress the formation of transfer film, thus resulting in increase in friction coefficients.
Research limitations/implications
The transfer film was rather thin, with thickness of 1-2 µm for most friction materials. That hindered the examination of mechanical properties of the transfer film, such as hardness.
Practical implications
This research explained the surroundings for transfer film formation, and its effect on friction coefficients. The research suggests to suppress the formation of transfer film to make friction materials with high friction coefficient, and the lubricating component MoS2 can be used for the purpose.
Social implications
Development of high-friction-brake materials conventionally depends on the use of strong abrasive components, which may induce attacking of counterpart disks. The enhancement of friction coefficients with addition of MoS2 content is expected to open a new prospect in development of high-performance friction materials, which can be applicable to brake pads for racing cars.
Originality/value
The study is in pursuit of the transfer film formation in successive friction stages, which revealed the conditions for transfer film generation and removal. Specimen preparation for SEM observation of cross section of friction surface was painstaking to not damage the developed friction surface. The study revealed the effect of different abrasive components on transfer film formation and the effect of lubrication contents of MoS2 on transfer film formation and friction coefficients.

Abstract
Purpose
This paper aims to investigate the temperature dependence of transfer film formation and friction coefficients in NAO friction materials with four different abrasive components, ZrO2, ZrSiO4, Al2O3 and Fe3O4.
Design/methodology/approach
8.5% SnS2 was added as a lubricating component to friction materials. Friction tests comprised 100 times of consecutive braking application for each friction material under constant temperature of 300°C, 400°C, 500°C and 600°C. After the friction tests, the friction surfaces of the counterpart disks were examined by scanning electron microscope to access the formation of transfer film.
Findings
Coefficients of friction depended on not only friction temperature but also friction history which is related to development of transfer film. The effect of the transfer film formation was to reduce the friction coefficients for most friction materials. Quantities of the transfer film formation varied with friction materials; at low temperature below 400° the transfer film formation was most active in the Fe3O4 materials, while at 600° it was the most active in the Al2O3 material. The effect of the lubricating component SnS2 was to suppress the formation of transfer film, thus enhancing friction coefficients.
Social implications
The enhancement of friction coefficients with addition of small amount of lubricating components such as SnS2 is expected to open a new approach in developing high performance-brake pads.
Originality/value
Temperature was the controlling parameter in the present test. Under these test modes, transfer film could be fully developed to access the role of the transfer film.

Abstract
Purpose
This study aims to determine the repurchase intention of food truck products based on perceived risks and perceived benefits by consumers within the context of Malaysia. Recently, the food truck industry has been expanding as customers begin to explore alternatives for food convenience. However, there are not many studies carried out on this topic, especially in Asian countries. This study will fill the gaps on the factors that affect repurchase intention, especially perceived risks and perceived benefits of food trucks products.
Design/methodology/approach
A cross-sectional online survey was conducted through Facebook Messenger and WhatsApp on consumers with prior experience in buying food truck products. The partial least square (PLS) modelling using the SmartPLS software was employed to analyse the data.
Findings
The results from 294 food truck consumers showed that perceived benefit, food safety, attitude and subjective norm significantly influence food truck products' repurchase intention. On the other hand, perceived risk towards the environment and perceived behavioural control do not substantially affect food truck products' repurchase intention.
Research limitations/implications
The data collected were related only to the food trucker's customer that operates in Malaysia. Thus, the results might be only applicable to similar other Asian or developing countries.
Practical implications
The results provided some managerial indicators to improve the level of business efficiency among food truck operators. Besides, marketers and policymakers can develop effective strategies and policies based on this study to develop this industry further.
Originality/value
The study gives a fresh overview of how the food truck business can improve its services in developing countries. The results offer a competitive advantage and how to strengthen customer retention that can improve business performance.

Abstract
Purpose
The purpose of this paper is to examine how corruption has changed over time in South Korea and to explore how the corruption control and prevention efforts of the Korean government have been successful and failed.
Design/methodology/approach
This paper draws on institutional theory to formulate a qualitative analysis to assess the effectiveness of anti-corruption policies and measures, and to identify the strengths and weaknesses of anti-corruption reform efforts in South Korea.
Findings
This paper argues that while the Korean government has been quite successful in building anti-corruption institutions to control low-level petty corruption, it has failed to institutionalize anti-corruption institutions to curb high-level grand corruption.
Originality/value
While many studies have attempted to identify the successful factors of fighting corruption, this paper draws a theoretical distinction between institution-building vs institutionalization to examine the success and failure of corruption control and prevention efforts in South Korea.

Abstract
The purpose of this chapter is to critically review the Korean Official Development Assistance (ODA) policy in terms of its context, actors, structures, and values so as to find how these characteristics are reflected in the education ODA of Korea. Previous studies, documents of Korean Government, and ODA-related statistics are reviewed. Self-confident in being transformed from a poor recipient country to a DAC donor, Korean government emphasizes the so-called Korean ODA Model in sharing its economic development knowledge and experiences with the developing countries. Despite the coordination effort by Prime Minister’s Office, government ministries tend to pursue its own ODA policies, while the finance ministry and the ministry of foreign affairs play major roles. As a result Korean ODA is economy-oriented, fragmented, and uncoordinated in planning and implementation. This study has found that such characteristics of Korean ODA are also reflected in the education ODA. For instance, TVET and higher education are the priority, while basic education is neglected, and the education ministry has its own ODA policies and programs. Outside studies on Korean ODA policy is rather scarce, furthermore, critical reviews other than policy advocacy are hard to find, particularly in English. This study will be a good start for further ones to understand the Korean ODA policy including education.

Abstract
Athlete activism has developed along with movements for human rights protection and promotion in Western societies. There have been many voices, active behaviors, and social movements that oppose and resist sexism, racism, or homophobia in society and sports. Unlike such sociopolitical occasions in the United States and European countries, neither strong voices nor active behaviors and organized movement against discrimination have existed in Korean society. Recently, incidents of violence at training facilities or athletes' dorm resulted in government policies centered for anti-violence. Structural factors limiting the outbreak and development of athlete activism were analyzed and discussed, including the conservative and authoritarian physical culture, the athletes' lack of awareness of social issues in sports, and the absence of governmental policies to combat and end sexism, racism, and homophobia in sports. Finally, this chapter explores several challenging plans to overcome structural constraints and build up, promote, and develop athlete activism in Korea as follows: First, it is to increase opportunities for student athletes to develop social awareness by normalizing their education and school life; second, it is to abolish the regulations that restrict student athletes graduating from high school to PE/sports/kinesiology major departments of universities; third, it is to greatly expand athletes' social networking and increase their social power. Finally, the chapter argues that the development of athlete activism protecting and promoting athletes' human rights can be an important turning point for Korea to leap forward as a sport democratized and advanced country.

Abstract
Purpose
This paper aims to examine how the relationship between abnormal audit fees and audit quality changed after adoption of the International Financial Reporting Standards (IFRS) in Korea.
Design/methodology/approach
Using empirical data collected over the period from 2008 to 2013, this study analyzes the association between abnormally high/low audit fee and audit quality. This study uses linear regression to test the hypothetical relation using discretionary accrual as a proxy for audit quality.
Findings
This study finds that there exists no significant relationship between abnormally high audit fees and audit quality measured by the magnitude of discretionary accruals in the pre-IFRS adoption period. However, the relationship between abnormally high audit fees and the magnitude of discretionary accruals turns to be positive in the post-IFRS adoption period. These finding suggests that the IFRS enables some clients to engage more discretion in the choice of discretionary accruals and auditors charge higher audit fees in return for allowing the discretion for such clients.
Practical implications
This study provides insight to regulators of the need to review carefully the financial statements of firms with abnormally high audit fees, and to investors to be more cautious when using financial information about these firms.
Originality/value
To the best of authors’ knowledge, this is the first study to assess IFRS impact on audit fee-quality relation. Also, unique Korean audit market with intensifying competition and discounting audit fee provides interesting setting to review the impact of abnormal audit fee on audit quality.

Abstract
There is significant amount of literature tackling different issues related to the port industry. The present chapter focuses on a single business unit of seaports aiming at the documentation of works related to container terminals.
An effort to review, collect and present the majority of the works present in the last 30 years, between 1980 and 2010, has been made in order to picture the problems dealt and methods used by the authors in the specific research field. To facilitate the reader, studies have been grouped under five categories of addressed problems (productivity and competitiveness, yard and equipment utilization, equipment scheduling, berth planning, loading/unloading) and four modelling methodologies (mathematics and operations research, management and economics, simulation, stochastic modelling).
The analysis shows that most works focus on productivity and competitiveness issues followed by yard and equipment utilisation and equipment scheduling. In reference to the methodologies used managerial and economic approaches lead, followed by mathematics and operations research.
In reference to future research, two fields have been identified where there is scope of significant contribution by the academic community: container terminal security and container terminal supply chain integration.
The present chapter provides the framework for researchers in the field of port container terminals to picture the so far works in this research area and enables the identification of gaps at both research question and methodology level for further research.
