Abstract
Two‐noded curved beam elements, CMLC and IMLC, are developed on the basis of Timoshenko’s beam theory and curvilinear co‐ordinates. These elements are developed by the separation of the radial displacement into the bending and the shear deflection and the projection of the shear deflection into bending deflection. In the CMLC element, field‐consistent membrane strain interpolation is adapted for removing the membrane locking. The CMLC element shows the rapid and stable convergence on the wide range of radius, thickness and length of the curved beam. The field‐consistent membrane strain and the separation of radial displacement produce the most efficient linear element possible.

Abstract
As the global economy continues to boom, there remains a significant need for more efficient transportation and effective management in corporate logistics. In this regard, railways have been considered one of the most efficient modes for long distance transportation. In Asia, there are several extensive and direct railroads such as the TSR (Trans-Siberian-Railroad), the TCR (Trans-Chinese-Railroad) and the TMR (Trans-Mongolian-Railroad) which could connect Asia to Europe. If these railroad networks such as the TKR (Trans-Korean-Railroad) were fully operational, it is expected that they would replace a major portion of the current global trade transportation with is sent through other shipping methods. Therefore, the development of railroad networks is one of the most important steps toward an integrated international transportation system. However, in reality, it is difficult to achieve this vision because of the political and economic problems surrounding multiple countries that this network must cut across. Moreover, it is difficult to ensure the railways’ economic competitiveness when it is compared with other logistics options. In this study, we aim to discover the status quo about railway networks by focusing on the TCR and TSR. Through in-depth interviews and surveys with actual users of these networks, current issues and problems are analysed in order to make suggestions for improvements. This research also provides meaningful insights which the TKR-TSR and TKR-TCR railway networks should consider if they want to continue to be successful in the future.

Abstract
Purpose
The purpose of this paper is to examine the roots of police corruption, evaluate the effectiveness of anti-corruption measures, and suggest recommendations to prevent and control police corruption in South Korea.
Design/methodology/approach
This paper adopts a qualitative approach to identify the key causes and to assess the reform agenda of police corruption in South Korea. In doing so, it introduces a brief history and profile of the police force, explores changes in police corruption, identifies the roots of police corruption, assesses the effectiveness of anti-corruption measures and offers policy recommendations to curb corruption in the South Korean police.
Findings
This paper claims that conventional and current anti-corruption measures have not been effective in minimizing police corruption in South Korea. It identifies the scope of police work and duties without proper accountability, a code of silence in police organizations, the low ethical standards of police officers and weak punitive measures against corrupt police officers as the main causes of corruption. Strenuous reform efforts that directly target these causes are needed to reduce corruption in the South Korean police.
Originality/value
This paper will be a useful reference for readers who are interested in why corruption has not been effectively prevented and controlled in the South Korean police.

Abstract
Purpose
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.
Design/methodology/approach
The analyzed data included survey responses from 246 foreigners who visited PyeongChang as a visitor for the 2018 Winter Olympics.
Findings
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.
Originality/value
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.

Abstract
Purpose
The solitary consumption market has grown in the hospitality industry. However, research on the behavior of solitary consumers and differences between solitary consumers of different nationalities is rare. The relationships between solo dining motivations and customer satisfaction were investigated for consumers in Taiwan and the United States.
Design/methodology/approach
A survey was conducted among Taiwanese and American consumers; 628 valid questionnaires were retrieved. Structural equation modeling was performed to test the hypotheses.
Findings
Significant differences were observed between Taiwanese and American consumer motivations. Higher solo dining motivation was positively associated with customer satisfaction; in particular, “escape and relaxation” and “enjoyment” were both positively associated with customer satisfaction. American consumers had a stronger relationship between motivation for social interaction and customer satisfaction.
Research limitations/implications
Only solo diners in Taiwan and the United States were investigated. The results might not be generalizable to solo diners in other regions.
Originality/value
The study's findings on the associations between solo dining motivations and consumption experience contribute to food consumption research. Furthermore, the results enable an understanding of differences in the motivations and behaviors of solitary consumers in different countries.

Abstract
Purpose
The purpose of this study is to confirm that the stiffness of fused filament fabrication (FFF) three-dimensionally (3D) printed fiber-reinforced thermoplastic (FRP) materials can be predicted using classical laminate theory (CLT), and to subsequently use the model to demonstrate its potential to improve the mechanical properties of FFF 3D printed parts intended for load-bearing applications.
Design/methodology/approach
The porosity and the fiber orientation in specimens printed with carbon fiber reinforced filament were calculated from micro-computed tomography (µCT) images. The infill portion of the sample was modeled using CLT, while the perimeter contour portion was modeled with a rule of mixtures (ROM) approach.
Findings
The µCT scan images showed that a low porosity of 0.7 ± 0.1% was achieved, and the fibers were highly oriented in the filament extrusion direction. CLT and ROM were effective analytical models to predict the elastic modulus and Poisson’s ratio of FFF 3D printed FRP laminates.
Research limitations/implications
In this study, the CLT model was only used to predict the properties of flat plates. Once the in-plane properties are known, however, they can be used in a finite element analysis to predict the behavior of plate and shell structures.
Practical implications
By controlling the raster orientation, the mechanical properties of a FFF part can be optimized for the intended application.
Originality/value
Before this study, CLT had not been validated for FFF 3D printed FRPs. CLT can be used to help designers tailor the raster pattern of each layer for specific stiffness requirements.

Abstract
Purpose
The purpose of this paper is to evaluate the effects of intermittent and continuous heating protocols using graphene-heated clothing and identify more effective body region for heating in a cold environment.
Design/methodology/approach
Eight males participated in five experimental conditions at an air temperature of 0.6°C with 40 percent relative humidity: no heating, continuous heating the chest, continuous heating the back, intermittent heating the chest, and intermittent heating the back.
Findings
The results showed that the electric power consumption of the intermittent heating protocol (2.49 W) was conserved by 71 percent compared to the continuous protocol (8.58 W). Rectal temperature, cardiovascular and respiratory responses showed no significant differences among the four heating conditions, while heating the back showed more beneficial effects on skin temperatures than heating the chest.
Originality/value
First of all, this study was the first report to evaluate cold protective clothing with graphene heaters. Second, the authors provided effective intermittent heating protocols in terms of reducing power consumption, which was able to be evaluated with the characteristics of fast-responsive graphene heaters. Third, an intermittent heating protocol on the back was recommended to keep a balance between saving electric power and minimizing thermal discomfort in cold environments.

Abstract
Purpose
Seekers who visit professional virtual communities (PVCs) are usually motivated by knowledge-seeking, which is a complex cognitive process. How do seekers search for knowledge, and how is their search linked to prior knowledge or PVC situation factors? From the cognitive process and interactional psychology perspectives, this study investigated the three-way interactions between seekers’ expertise, task complexity, and perceptions of PVC features (i.e. knowledge quality and system quality) on knowledge-seeking strategies and resultant outcomes.
Design/methodology/approach
A field experiment was conducted with 119 seekers in a PVC using a 2 × 2 factorial design of seekers’ expertise (i.e. expert versus novice) and task complexity (i.e. low versus high).
Findings
The study reveals three significant insights: (1) For a high-complexity task, experts adopt an ask-directed searching strategy compared to novices, whereas novices adopt a browsing strategy; (2) For a high-complexity task, experts who perceive a high system quality are more likely than novices to adopt an ask-directed searching strategy; and (3) Task completion time and task quality are associated with the adoption of ask-directed searching strategies, whereas knowledge seekers’ satisfaction is more associated with the adoption of browsing strategy.
Originality/value
We draw on the perspectives of cognitive process and interactional psychology to explore potential two- and three-way interactions of seekers’ expertise, task complexity, and PVC features on the adoption of knowledge-seeking strategies in a PVC context. Our findings provide deep insights into seekers’ behavior in a PVC, given the popularity of the search for knowledge in PVCs.
