Abstract

Purpose

Increasingly 3D printing is used for parts of garments or for making whole garments due to their flexibility and comfort and for functionalizing or enhancing the aesthetics of the final garment and hence adding value. Many of these applications rely on complex programming of the 3D printer and are usually provided by the vendor company. This paper introduces a simpler, easier platform for designing 3D-printed textiles, garments and other artifacts, by predicting the optimal orientation of the target objects to minimize the use of plastic filaments.

Design/methodology/approach

The main idea is based on the shadow-casting analogy, which assumes that the volume of the support structure is similar to that of the shadow from virtual sunlight. The triangular elements of the target object are converted into 3D pixels with integer-based normal vectors and real-numbered coordinates via vertically sparse voxelization. The pixels are classified into several groups and their noise is suppressed using a specially designed noise-filtering algorithm called slot pairing. The final support structure volume information was rendered as a two-dimensional (2D) figure, similar to a medical X-ray image. Thus, the authors named their method modified support structure tomography.

Findings

The study algorithm showed an error range of no more than 1.6% with exact volumes and 6.8% with slicing software. Moreover, the calculation time is only several minutes for tens of thousands of mesh triangles. The algorithm was verified for several meshes, including the cone, sphere, Stanford bunny and human manikin.

Originality/value

Simple hardware, such as a CPU, embedded system, Arduino or Raspberry Pi, can be used. This requires much less computational resources compared with the conventional g-code generation. Also, the global and local support structure is represented both quantitatively and graphically via tomographs.

Abstract

In this paper, we examine the comparative advantage of Korea and China while focusing on their technology level. The three digit SITC (Standard International Trade Classification) data is classified by technology level and the revealed comparative advantage (RCA) is derived from 1992-2009 by using UN COMTRADE data. For careful interpretation of the comparative advantage and technology levels, we also examined intra-industry trade and unit values of bilateral Korea-China trade, and semi-conductor industry technology. We found that the revealed comparative advantage has moved from low technology products to high technology products in Korea. China still maintains a comparative advantage in low technology products such as textiles and clothing, but at the same time, China’s high and medium-high technology products have recently gained a comparative advantage. The perception that China only has a comparative advantage for labor intensive products with low technology should be changed based on our analysis. However, China’s advancement in technology should not be overestimated. When comparing the unit value of basic materials of Korea’s and China’s exports, we found that Korea’s export product prices are on average higher than that of China’s, although the gap is reducing. A wider technology gap between Korea and China still exists in the semi-conductor industry, which is one of the most advanced high technology industries throughout the world.

Abstract

The economic success of East Asia was due to an export-led growth strategy, which was heavily dependent on the global trading system underpinned by the General Agreement on Tariffs and Trade (GATT) and the World Trade Organization (WTO). In recent years, however; East Asian countries have shifted their trade policy focus to regional agreements and made Free Trade Agreements (FTAs) among themselves arid with other regions. Government organization has been restructured to increase FTA activities. Generally, the current literature predicts that FTA activities of East Asia would help to increase the welfare of the region. In this paper; we offer a critical assessment of East Asia FTAs. We note that East Asia FTAs provide incomplete coverage of sectors and are likely to lead to an inefficient resource allocation. FTA movements are not matched with actual trade flows. The benefits of East Asia FTAs are fairly limited and potential benefits, if any, would not likely be materialized in the near future. Our overall assessment is that the recent policy shift in East Asian countries from multilateral trade orientation or unilateral action to regionalism or a parallel multilateral and regional trade approach will not produce much gain. The governments should increase their efforts at economic reform and reduce barriers to trade and investment, rather than to allocate more resource and manpower to FTA activities.

Abstract

This paper examines global imbalance and rebalancing issues from the viewpoint of Korea. As IMF (2009) notes, the unwinding of global imbalance seems inevitable and, in fact, it is in progress. We illustrate that Korea, with a flexible exchange rate system and relatively balanced current accounts, has little direct linkage to global imbalance. However, we also find that Korea is not immune to the costly adjustment process of imbalance due to the triangular trade between Korea, China and the U.S. The fact that Korea is ‘indirectly’ linked to global imbalance limits Korea’s ability to cope with the situation. Boosting domestic demand, often mentioned recommendation for East Asia, is not an appropriate solution for Korea with low personal savings rate. A lot depends on China’s policy. If China reduces its dependence on U.S. market and increases domestic consumption despite unemployment risk in export manufacturing sector, it will provide Korea with an opportunity for more stable growth based on China’s final demand. Korea can also make efforts to increase economic integration and expand monetary cooperation in Asia that would help to increase consumption demands and final goods trade in the region.

Abstract

Purpose

This article aims to comment on how the empirical research on board effectiveness in crisis contexts has been evolving over time. Over the years, the empirical evidences have demonstrated that particular board features can improve the survival chances of firms suffering a crisis and, to date, experts agree that discussing these evidences is necessary for the further improvement of knowledge in this field.

Design/methodology/approach

This is a critical review article.

Findings

Valuable evidences emerge from the review. For example, it seems that board independence has a key role in enhancing the performance of firms suffering a crisis. At the same time, the review suggests that further refinement is needed for supporting (or eventually refuting) the idea that boards and/or Chief Executive Officers (1) must be replaced to achieve successful turnaround strategies.

Originality/value

On the basis of its findings, the review also prospects a number of conceptual and methodological implications for the future research and practice about board effectiveness in corporate crises. For example, these implications are associated with future investigations about the executives’ sociodemographic features and personality traits as well. More international comparisons seem also needed to improve the reliability of the extant knowledge.

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

This paper aims to understand the impact of smart working on employees’ quality of life. The service-dominant logic indicates that key actors, including employees, are resource integrators. This empirical study contributes to the current knowledge of transformative service by expounding on smart working practices and their relationship with self-efficacy and, ultimately, quality of life of employees.

Design/methodology/approach

This study contends that smart working enhances employees’ self-efficacy. The current research uses conservation of resources (COR) theory as a basis in hypothesizing that self-efficacy serves as a key resource, which can stimulate workplace creativity, job satisfaction and quality of life. An onsite survey is conducted among employees who have been involved in smart working in the travel agency context.

Findings

Smart working has a positive effect on self-efficacy, which positively influences workplace creativity, job satisfaction and quality of life. Workplace creativity enhances job satisfaction but does not influence quality of life. Job satisfaction boosts quality of life, which is important to tourism services and their employees amid various crises.

Research limitations/implications

Consistent with COR theory, the immediate recommendation to managers is to invest in smart working, which can lead to employees’ creativity, job satisfaction and quality of life.

Originality/value

To the best of the authors’ knowledge, this empirical study is the first to assess the viability of smart working in the travel agency context. Smart working offers positive outcomes, such as convenience for employees to work independently, improving workplace creativity, job satisfaction and quality of life. Travel agencies are mainly categorized as small and medium enterprises (SMEs). In the future, SMEs may also introduce smart working that can eventually become their competitive advantage to retain talented employees.

El trabajo inteligente en las agencias de viajes y la calidad de vida de los empleados

Resumen

Propósito

Este artículo tiene como objetivo entender el impacto del trabajo inteligente en la calidad de vida de los empleados. Basándose en la lógica de servicio dominante, los actores clave, incluidos los empleados, son integradores de recursos. Este estudio empírico contribuye al conocimiento actual de lo que constituye un servicio transformador al exponer prácticas laborales inteligentes y su relación con la autoeficacia y, en última instancia, la calidad de vida de los empleados.

Diseño/Metodología/Enfoque

Este estudio sostiene que el trabajo inteligente mejora la autoeficacia de los empleados. Plantea la hipótesis de que la autoeficacia sirve como un recurso clave que puede estimular la creatividad en el lugar de trabajo, la satisfacción laboral y la calidad de vida utilizando la teoría de la conservación de recursos. Se ha realizado una encuesta in situ entre los empleados que han llevado a cabo trabajo inteligente en el contexto de la agencia de viajes.

Resultados

El trabajo inteligente tiene un efecto positivo en la autoeficacia que influye positivamente en la creatividad en el lugar de trabajo, la satisfacción laboral y la calidad de vida. La creatividad en el lugar de trabajo mejora la satisfacción laboral, pero no influye en la calidad de vida. La satisfacción laboral mejora la calidad de vida, lo que es importante tanto para los servicios turísticos como para sus empleados durante las crisis.

Implicaciones

De acuerdo con la teoría de la conservación de recursos, la recomendación inmediata a los gerentes es invertir en un trabajo inteligente que pueda conducir a la creatividad, la satisfacción laboral y la calidad de vida de los empleados.

Originalidad/Valor

Este estudio empírico es el primero del que tengamos constancia en evaluar la viabilidad del trabajo inteligente en el contexto de la agencia de viajes. El trabajo inteligente ofrece beneficios, como la posibilidad de que los empleados trabajen de forma independiente, mejorando así la creatividad profesional, la satisfacción laboral y la calidad de vida. Las agencias de viajes se incluyen principalmente en la categoría de pequeñas y medianas empresas (pymes). En el futuro, las pymes también pueden introducir el trabajo inteligente, que puede llegar a convertirse en su ventaja competitiva para retener a los empleados con talento.

Abstract

Purpose

The purpose of this paper is to outline a framework for marketing cultural goods (e.g. music) to global markets by examining modes of entry and positioning strategies used by media producers of the South Korean music industry.

Design/methodology/approach

An historic analysis was implemented to investigate the modalities and structures through which cultural products are produced and disseminated. Data for this study came from 314 articles collected from www.allkpop.com, a leading English-language, South Korean popular culture news site.

Findings

The cultural technology framework consists of the institutionalization of cultural technology, exportation of cultural content, collaborations with local talent, and joint ventures with local markets.

Research limitations/implications

The findings emerge from an analysis of South Korean popular music industries, and further research is needed to generalize the results across cultural industries.

Practical implications

The cultural technology framework can be applied to cultural industries such as music, film, comics, and art, where culture and language could be barriers to adoption.

Originality/value

This study outlines a framework for the modes of entry and positioning strategies of cultural goods (e.g. music) in international markets. Extant literature has examined global marketing from the purview of durable consumer goods and brands, with limited insights into cultural products. More broadly, this paper addresses the call for more qualitative inquiry into international marketing topics.
