Building on the first cross-national study that had demystified various assumptions about the worldwide use of shadow education two decades ago, we analyze data from the 2012 Programme for International Student Assessment to examine the cross-national pattern of the use of shadow education by families in 64 nations and use improved statistical estimation methods. Focusing on fee-paying out-of-school classes, we find a continued, and likely an intensified pattern of the cross-national use of shadow education in the contemporary world. Approximately about one-third of all 15-year-old students from 64 countries/economies across the world use this form of shadow education. Students of higher socioeconomic status, females, and students in urban areas and general programs are more likely to use fee-paying services, while families and students turn to these services to address academic deficiencies in general. In addition, students from poorer countries more extensively rely on shadow education than students from wealthier countries after controlling for other variables. Students in South-Eastern and Eastern Asian countries are more likely to pursue shadow education than their counterparts in many other regions. Implications of these findings for theories of education and society as well as for educational policy in relation to shadow education are discussed.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

This study aims to conduct socio-technical analysis of the rapidly evolving Internet of Things (IoT) ecosystem and industry, including such factors as market growth and user experiences, policy and the impact of IoT on various areas.

By applying a multi-level socio-technical framework to IoT in South Korea, this study seeks an ecological understanding of how IoT will evolve and stabilize in a smart environment.

The study shows the values influencing potential users’ adoption of IoT by integrating cognitive motivations and user values as primary determining factors. Along with user modeling, the findings reveal the challenges of designing, deploying and sustaining the diverse components of IoT, and provides a snapshot of Korea’s current approach to meeting these challenges.

The study’s findings offer a contextualized socio-technical analysis of IoT, providing insight into its challenges and opportunities. This insight helps to conceptualize how IoT can be designed and situated within human-centered contexts.

The purpose of this study is to examine the branding strategies of SMEs from NIEs, juxtaposing the different strategies used to specifically target developed and developing countries with regard to brand-building approach, type and number of brands and degree of standardization.

A case-study approach is used. In-depth interviews are conducted with 10 Korean consumer-goods SMEs exporting their own in-house brands.

Clear differences emerge between the strategies of SMEs entering developed countries and those entering developing countries, particularly regarding brand identity development, use of foreign sales subsidiaries and number and types of brands used. The authors find an interaction effect between product characteristics and host market levels of economic development, both of which influenced the degree of product standardization.

This study is the first attempt to uncover the branding strategies of NIE consumer-goods SMEs. The findings contribute to the field by extending our understanding of branding strategies used by consumer-goods SMEs from NIEs, thereby providing useful insight for other NIE enterprises when establishing branding strategies aimed at foreign markets.

Contrary to the mainstream born global (BG) perspective, some previous studies report the incremental expansion of BGs. In addition, the reasons behind BGs initiating specific steps, if any, and BGs’ entry market choices are still unknown or rather contrasting. This study views that such contrasting findings may be attributed to the contexts in which BGs operate. Within the context of consumer goods BGs, the purpose of this paper is to examine the entry market choices and post-entry growth patterns, and investigate the underlying reasons.

This study adopted in-depth historiographic case research from seven Korean BGs in the consumer goods sector that demonstrated success in internationalization. Multiple sources were used to gather data from each case. A total of 14 interviews, approximately two one-on-one interviews per firm, were the major means of data collection.

The findings revealed that first entry market choices among BGs functioned largely as attempts at emergent opportunities. However, after the first wave of entry into countries with available selling opportunities, entry market choice became a simultaneous pursuit of strategic markets and emergent selling opportunities. BGs focusing on image-oriented consumer goods appeared more strategic when entering the world’s leading markets to gain brand reputation. The analyses of internationalization processes revealed three patterns, which collectively implied that each move to the next stage came from a strategic decision to solve the problems related to survival and strategic visions for growth.

One contribution of this paper is the provision of empirical evidence for entry market choices among consumer goods BGs. The findings suggest that BGs’ entry market choices may not be a simple matter of simultaneous expansion to the world’s lead market. Instead, they may comprise more strategic decision. While previous studies have suggested such evolutionary or path-dependent internationalization processes, this study is among the first to reveal specific growth patterns and the possible reasons behind them.

The purpose of the study was to confirm the mediating effect of perceived quality in the relationship between two extrinsic cues (brand name and country of origin)and perceived value previously tested by Teas and Agarwal (2000) using more rigorous statistical techniques - regression analysis and structural equation modelling (SEM) - in a sports consumption context. Data were collected from 194 members of the Korea University Ski Team Association. Based on the results, the partially mediated model was selected as the best fitting model. From a marketing perspective, ski marketers need to understand that the two extrinsic cues had direct and indirect influences through perceived quality on perceived value of the ski product.

Among a wide array of information and communication technologies (ICTs) used to directly or indirectly support the mega events are reality boosting technologies and smart tourism technologies. Building upon the halo effect, this study aims to explain the connection between satisfaction with ICTs used in mega event, national image and event participants’ future behavior.

The analyzed data included survey responses from 246 foreigners who visited PyeongChang as a visitor for the 2018 Winter Olympics.

The results showed that both reality boosting technologies and smart tourism technologies directly or indirectly influence overall experience satisfaction by way of transaction satisfaction. Furthermore, the two types of satisfaction were found to positively influence the national image of the host country, which consequently has a positive effect on visitors’ future behavior.

This study aimed to explore two different roles of ICTs in mega events by focusing more on the visitors who came to PyeongChang for the Olympics. The originality of this study lies in its attempt to examine the mechanisms in which visitors’ satisfaction from ICT-based experiences in mega events contributes to forming a positive image toward the host country.
