The objective of the study is to propose the catch-up strategy of Hyundai Kia to become the globally leading company in the automobile industry. For this, we try to compare Hyundai Kia with three leading automobile companies: Toyota, VW, and GM by using the Generalized Double Diamond Model. As a result, we present three ways that Hyundai Kia can become a "First Mover." The three strategies are : 1) controlling increase of wage, raising productivity, and increasing R&D investment 2) increasing overseas investment of the small and medium sized automobile factories 3) pursuing the two tracks strategy of a public car and a prestige car more aggressively. This study is significant in the fact that it presents the catch-up strategy of Hyundai Kia in the automobile industry, of which the leaders can not be changed easily, by the Generalized Double Diamond Model approach.

The effects of actively stimulating devices (ASD) on juvenile flatfish escape were studied to increase escape rates from the cod end by encouraging fish to approach the net wall. Two kinds of ASD were designed: a fluttering net panel, i.e., a free-end flag-like net panel, and a double conical rope array. Escape responses of juvenile bastard halibut were observed in a circulating water channel using two model cod ends, one made with diamond-shaped 43-mm-mesh-size polyethylene (PE) as a high-contrast cod end and the other with polyamid (PA) mono-ply as a low-contrast cod end. Retention rate was significantly lower with the double conical rope-array ASD in the PE cod end than with conventional PE cod ends only or the fluttering net-panel ASD inside the PE cod end. Mean retention rate with the low-contrast PA cod end was also significantly lower than that with the high-contrast PE conventional cod end. Therefore, active fluttering devices using a double conical rope array together with less visible low-contrast netting in the cod end could help to reduce the bycatch of juvenile flatfish by weakening their optomotor response and actively driving fish to the side net panel.

One of the main applications of seismic risk assessment is that an specific design could be selected for a bridge from different alternatives by considering damage losses alongside primary construction costs. Therefore, in this paper, the focus is on selecting the shape of pylon, which is a changeable component in the design of a cable-stayed bridge, as a double criterion decision-making problem. Different shapes of pylons include H, A, Y, and diamond shape, and the two criterion are construction costs and probable earthquake losses. In this research, decision-making is performed by using developed seismic risk assessment process as a powerful method. Considering the existing uncertainties in seismic risk assessment process, the combined incremental dynamic analysis (IDA) and uniform design (UD) based fragility assessment method is proposed, in which the UD method is utilized to provide the logical capacity models of the structure, and the IDA method is employed to give the probabilistic seismic demand model of structure. Using the aforementioned models and by defining damage states, the fragility curves of the bridge system are obtained for the different pylon shapes usage. Finally, by combining the fragility curves with damage losses and implementing the proposed cost-loss-benefit (CLB) method, the seismic risk assessment process is developed with financial-comparative approach. Thus, the optimal shape of the pylon can be determined using double criterion decision-making. The final results of decision-making study indicate that the optimal pylon shapes for the studied span of cable-stayed bridge are, respectively, H shape, diamond shape, Y shape, and A shape.

The purpose of this study is to design an effective innovation model for communication-centered public services, based on the case of Korea Midland Power Co., Ltd (KOMIPO). This study analyzed customer and employee participation activities at KOMIPO, focusing on communication activities to derive the best practices. The study comprised of the following stages: (1) Preparation stage to assess the current situation and promote change management; (2) Problem-solving stage for improving public services; (3) Problem-solving stage for improving work processes; (4) Problem-solving stage for strengthening collaboration, and (5) Design stage for an innovation model. Based on the results of this study, an innovation model was developed for public services by applying the double-diamond design process. The proposed model presents a process structure, which is derived through an iterative process of primary divergence (discovery) and convergence (definition), and secondary divergence (development) and convergence (delivery). This study also proposed the possibility of applying the Idea-Power-Plant activities of KOMIPO's best practices to the proposed model. While this study proposed an innovation model for communication-centered public services through the analysis of a specific public company, the results of the study provide broad insights for effective operations management through efficient communication based on the participation of customers and employees in public institutions.

This study uses the bidet 4D double diamond design process model to propose an improvement for "senior-oriented bidet product service design" that reflects the characteristics and needs of seniors. This study was based on the product service system concept. To this end, qualitative research on seniors was conducted to derive user value factors, and, based on this, product service ideas were discovered, and a prototype reflecting the usefulness review of a working-level expert group was proposed. First, a "smart application service for user-customized function setting guide" was proposed. A bidet incorporating Internet of Things technology and a smart phone are linked to provide an app service that automatically interprets user characteristic information and information on bidet products to guide customized functions. Second, a control panel and remote control user interface to "user-oriented product service interface" was proposed. In consideration of the usability and cognitive ability of seniors, a simple and intuitive physical user interface such as a configuration centered on main functions, button arrangement according to task sequence, and a touch screen remote control was presented. Third, we proposed a "bidet care service linked with products and health/hygiene care" that provides a wide range of services such as user health and hygiene, cleanliness, entertainment, etc., in addition to regular bidet product service. This study proposed a product-based service design methodology that can improve user experience and relationship quality by discovering and improving the pain points and needs of users (seniors) in the process of using bidet products (before, during, and after use).

In recent years, Project Management Consultant(PMC) project has been emerging as a high-value-added engineering project. However, domestic engineering firms have difficulties in entering the overseas PMC market because of poor project performance and lack of PMC capabilities. To overcome these limitations, this study analyzes the key competitiveness factors for successfully performing the global PMC projects. PMC competency factors based on Porter's double diamond theory were extracted, and a questionnaire survey was conducted on domestic and overseas engineering firms. In addition, the important PMC competency factors were derived through paired t-test and IPA matrix analysis. As a result, the PMC competitiveness of domestic engineering firms was analyzed as around 60% compared to that of global engineering firms. Furthermore, 'PMC track records' and 'project management/owner response skills' were identified as top priority competency factors which are the most necessary factors for present domestic engineering firms. This study is expected to support to establish the international PMC market entry strategies by providing priorities of key competitiveness factors.
