Abstract

Purpose

This study aims to investigate the effects of two visual design principles, repetition and compositional lines, in a food image on purchase intention in the context of a mobile food delivery app and test the effect of crossmodal correspondences between vision and taste as a processing mechanism.

Design/methodology/approach

In this study, two experiments were conducted using burgers and iced tea as stimuli.

Findings

The results demonstrate that repetition of an identical food product increases visual appeal for both burgers and iced tea. However, the optimal level of repetition was different between the two products. The findings show that different compositional lines generate different levels of visual appeal and the effects of compositional lines vary between burgers and iced tea. The results also validate the serial mediation effects of vision and taste between design principles and purchase intention.

Originality/value

The findings of this study add substantially to the understanding of visual information processing in food retailing by demonstrating how design principles such as repetition and compositional lines facilitate crossmodal responses between vision and taste and influence purchase decisions in a mobile platform. Also this study provides guidance as to how food retailers use design principles (e.g. repetition and compositional lines) for different products effectively when the food retailers develop visual digital content for a mobile app.

Abstract

Purpose

The purpose of this paper is to investigate whether guests’ tipping motivations (i.e. server quality, social norm and food quality) and demographic characteristics (i.e. gender, age and income) influence loyalty to the server in a restaurant.

Design/methodology/approach

Based on a national online survey consumer panel comprised of 468 participants, the authors utilized decision tree using R statistical software. Predictor variables were tipping motivations and demographic characteristics (age, gender and income). Target variable was loyalty to the server.

Findings

The findings suggest that social norm, food quality and income influence customers’ loyalty toward the same server on future visits. Social norm turned out to be the strongest predictor. If consumers did not have high social norm on tipping, their loyalty toward a particular server was affected by the combination of determinants such as server quality, social norm, income and food quality.

Research limitations/implications

Future research can identify or develop scales of tipping motivations with stronger reliabilities in the context of restaurants. Future research can also explore other demographic differences (e.g. ethnicity and sexual orientation) in tipping motivations and server loyalty.

Practical implications

Servers are indeed the primary contact point and they are in the most influential position with consumers. Overall, results of this study provide an interesting insight in that restaurant guests’ experience can be ruined by bad quality of food or can be mitigated by server quality. Thus, this research highlights a step-by-step process as to the actions that a server may perform and manage in order to enhance server loyalty.

Originality/value

Loyalty has been examined in the context of products, brands or service providers. This study focuses on loyalty toward a specific server, because the consideration of server–guest relationship provides both a compelling and timely area of study in that restaurants continue to look for unique ways to drive server–guest rapport and customer loyalty.

Abstract

This study aims to analyze information on vessel traffic between the two Koreas with a probability distribution for each route/vessel type. The study will then conduct an estimate for maritime transport patterns of inter-Korean trade in the future. To analyze the flow of inter-Korean coastal shipping, this study conducted visualization analysis of shipping status between North and South Korea by year, ship type, and port using navigation data of three years from Port Logistics Information System (Port-MIS) sources during 2006 to 2008, which saw the most active exchanges between the two governments. Also, this study analyzes shipping status between the two governments as a probability distribution for each port and provides the prospects for future maritime transport for inter-Korean trade by means of Bayesian Networks and simulation. The results of the analysis are as follows: i) when North-South routes are reopened, the import volume for sand from North Korea will be increased; ii) investment in the modernization of ports in North Korea is required so that shipping companies can generate profit through economies of scale; iii) the number of the operating vessels including container ships between the two governments is expected to increase like when the tensions and conflict on the Korean Peninsula was release, especially between Busan port in South Korea and Nampo port in North Korea; and iv) among container ships, transshipment containers imported and exported through Busan Port will be shipped to North Korea by feeder transportation.

Abstract

Busan (Pusan), Korea’s second largest city (population 3.6 million) and fifth busiest port in the world, is experiencing rapidly increasing trade, global connections, events, and resulting infrastructural projects. What should Busan do to better handle the social, political, and economic complexities brought by these changes?

To answer this question, this paper explores the relationship of globalization and culture, as treated by cultural anthropology. It also considers how the tools of applied social science and anthropology can be mobilized to help Busan and the southeast region of Korea deal with these challenges.

After introducing anthropological treatments of culture, globalization and global problems, I discuss how applied social science/anthropology is used in international business/trade, tourism, and transport/logistics, especially the third area. To show how applied social science can help transportation and logistics projects in Busan and Korea, I present lessons from case studies and examples in Denver, Colorado Springs, Chuuk (Truk, South Pacific), and Korea.

Applied social science and applied anthropology present a wealth of helpful methods and insights to help Busan and Korea improve planning, public participation, political, social and environmental issues in transport and logistics projects, and to help prevent ethical and budgetary lapses. Finally, I offer suggestions for initial training programs and future studies to help expedite these goals.

Abstract

This research is to investigate the effect of the improvement of investment environments with investment incentive on Korean national economy by looking into the foreign investment support system in Korea. To this end, first research model was set up based on our literary study and case study was conducted on 150 foreign companies that were located in industrial complex for foreign companies, received the tax benefit and government subsidization. And it was found that even though the foreign companies were contributing to the national economy in general such as in the area of production, export, employment, development of technology, there was no significant contributory difference between the investment incentive beneficiary and non‐beneficiary foreign companies. Therefore it deemed reasonable to reconsider the way Korean government supports foreign companies in Korea and to reinforce foreign companies’ relevance to national policy agenda with additional incentives to foreign companies located in comparatively less developed areas. As a way to promote foreign investment, promotion of investment infra such as improvement of follow‐up services, openness to foreign investment, industrial deregulations in capital area, revitalization of free economic zone, efficient system to promote foreign investment and the reinforcement of public relations were considered necessary, especially the upgrading of economic structure and the integrated management of domestic and foreign investors deemed necessary for the optimal distribution of the industries.

Abstract

Purpose

Business, management and accounting (BMA) papers published from The Middle East and North Africa (MENA) region, account for less than 1 per cent of the total papers published. As nations in MENA try and compete on the national competitive index, there is a tendency to adopt performance appraisal criteria from more established research nations. MENA accounts for 6 per cent of world population, and has one of the world's highest growth rates at 3 per cent. Since over one‐third of the population is under 15, if factors that hider and encourage research are identified, the research output can be increased. As it is clear that research on this region and from researchers in MENA is low, the purpose of this paper is to focus on how to increase research on this region.

Design/methodology/approach

Since there is very little information from this region, the research was exploratory in nature. Interviews with academics, officers in charge or research grants, publishers and senior managers from industry using and conducting research were used as a basis to identify research barriers and methods to overcome barriers. This was triangulated with secondary data from existing academic research, industry and NGO reports and research seminars and discussions.

Findings

The barriers and strategies to overcome research can be classified into three categories based on key stakeholders: the government (or policy makers); the industry or market conditions; and the institutions. Strategies at the individual academic level are also identified, which may overcome more macro environmental limitations.

Originality/value

This paper is the first of its kind in this region that consolidates many aspects and helps new researchers manage and improve research productivity. The paper is of value to any researcher but especially to policy makers, academics, promotion boards and universities that have doctoral programs.

Abstract

The purpose of this chapter is to trace the long-term trend of professionalization of the military and the civil–military relations of modern Korea. It reviews the patriarchal relation between the king and the military officer in ancient Korea and how the patron–client relations of a parochial society have continued between the political ruler and the military of modern Korea. The history of modern Korea is examined according to the level of development and the nature of civil–military relations. The Korean military has gradually changed from a parochial army to a professional one, and the civil–military relations of modern Korea have been normalized.

Abstract

Purpose

Despite the many advantages this type of equipment offers, there are still some major drawbacks. Linear cutting machine (LCM) cannot accurately simulate the true rock-cutting process as 1. it does not account for the circular path along which tunnel boring machine (TBM) disk cutters cut the tunnel face, 2. it does not accurately model the position of a disk cutter on the cutterhead, 3. it cannot perfectly replicate the rotational speed of a TBM. To enhance the knowledge of these issues and in order to mimic the real rock-cutting process, a new lab testing equipment was developed by Hyundai Engineering and Construction.

Design/methodology/approach

A new testing machine called rotary cutting machine (RCM) is designed to simulate the excavation process of hard-rock TBMs and includes features such as TBM cutterhead, RPM simulation, constant normal force mode and constant penetration rate mode. Two sets of tests were conducted on Hwandeung granite using different disk cutter sizes to analyze the cutting forces in various excavation modes. The results are analyzed using statistical analysis and dimensional analysis. A new model is generated using dimensional analysis, and its results are compared against the results of actual cases.

Findings

The effectiveness of the new RCM test was demonstrated in its ability to apply various modes of excavation. Initial analysis of chip size revealed that the thickness of the chips is largely dependent on the cutter spacing. Tests with varying RPM showed that an increase in RPM results in an increase in the normal force and rolling force. The cutting coefficient (CC) demonstrated a linear correlation with penetration. The optimal specific energy is achieved at an S/p ratio of around 15. However, a slightly lower S/p ratio can also be used in the design if the cutter specifications permit. A dimensional analysis was utilized to develop a new RCM model based on the results from approximately 1200 tests. The model's applicability was demonstrated through a comparison of TBM penetration data from 26 tunnel projects globally. Results indicated that the predicted penetration rates by the RCM test model were in good agreement with actual rates for the majority of cases. However, further investigation is necessary for softer rock types, which will be conducted in the future using concrete blocks.

Originality/value

The originality of the research lies in the development of Hyundai Engineering and Construction’s advanced full-scale laboratory rotary cutting machine (RCM), which accurately replicates the excavation process of hard-rock tunnel boring machines (TBMs). The study provides valuable insights into cutting forces, chip size, specific energy, RPM and excavation modes, enhancing understanding and decision-making in hard-rock excavation processes. The research also presents a new RCM model validated against TBM penetration data, demonstrating its practical applicability and predictive accuracy.

Abstract

Purpose

Limited by the types of sensors, the state information available for musculoskeletal robots with highly redundant, nonlinear muscles is often incomplete, which makes the control face a bottleneck problem. The aim of this paper is to design a method to improve the motion performance of musculoskeletal robots in partially observable scenarios, and to leverage the ontology knowledge to enhance the algorithm’s adaptability to musculoskeletal robots that have undergone changes.

Design/methodology/approach

A memory and attention-based reinforcement learning method is proposed for musculoskeletal robots with prior knowledge of muscle synergies. First, to deal with partially observed states available to musculoskeletal robots, a memory and attention-based network architecture is proposed for inferring more sufficient and intrinsic states. Second, inspired by muscle synergy hypothesis in neuroscience, prior knowledge of a musculoskeletal robot’s muscle synergies is embedded in network structure and reward shaping.

Findings

Based on systematic validation, it is found that the proposed method demonstrates superiority over the traditional twin delayed deep deterministic policy gradients (TD3) algorithm. A musculoskeletal robot with highly redundant, nonlinear muscles is adopted to implement goal-directed tasks. In the case of 21-dimensional states, the learning efficiency and accuracy are significantly improved compared with the traditional TD3 algorithm; in the case of 13-dimensional states without velocities and information from the end effector, the traditional TD3 is unable to complete the reaching tasks, while the proposed method breaks through this bottleneck problem.

Originality/value

In this paper, a novel memory and attention-based reinforcement learning method with prior knowledge of muscle synergies is proposed for musculoskeletal robots to deal with partially observable scenarios. Compared with the existing methods, the proposed method effectively improves the performance. Furthermore, this paper promotes the fusion of neuroscience and robotics.
