This study presents a research model that demonstrates the dominant design technology strategy for developing and securing dominant design technology based on open innovation. For this purpose, this study developed a strategic model for the development and acquisition of design technology, production technology, and production system of propeller which satisfies the requirements of ship propulsion system required by ship owners and shipbuilders. By studying large propellers for ships, it is possible to embody a strategic model that can be used as a technology development strategy of dominant design that is effective in technology field of other industries. In this study, HSP (High Skewed Propeller) strategy of Hyundai Heavy Industries, which occupies the largest global market share (47.5%, 2007) for more than 30 years until now, is analyzed as a successful case to verify this strategic model. The development and acquisition strategy model of dominant design technology presented in this study consists of four stages : dominant design project strategy, dominant design engineering technology strategy, dominant design production technology strategy, and dominant design production system strategy. The strategic model summarizes the key activities at each stage. In addition, the steps and core activities of this strategic model were confirmed through the case study. As a technology development strategy of HSP products, Hyundai Heavy Industries utilized open innovation technology to cooperate with outside, that is, collaborative research and development with KAIST (Korea Advanced Institute of Science and Technology) research team, and succeeded in achieving technology development of dominant design of HSP products by linking it with HSP technology development and acquisition strategy.

This paper proposes an integrative framework for determining a dominant design in the mobile operation systems. A dominant design has emerged as a de facto standard from traditional industries to ICT. ICT-related industries have been reorganized around the mobile industry in which the mobile operation system can be seen as a strategical keystone. In this paper, we develop a holistic approach for the emergence of a dominant design in the mobile operation systems. Firstly, we combined an integrative framework based on previous research findings with new determinants derived from cases of the mobile operation systems. Secondly, we categorized all determinants according to technological, firm-level and environmental factors within our proposed framework. Finally, we compared this framework to patterns coded from cases which include Android and iOS. This results show that a dominant design is likely to emerge as a result of the interaction of the determinants, not the influence of a single determinant. Furthermore, our proposed framework may extend the existing literature on dominant designs in both researchers and practitioners and provide implications to actors for establishing a competition strategy in the mobile telecommunication ecosystems.

본 연구는 디자인요소의 변화과정을 통해 제품디자인요소(product design factors)의 지배력 정도(dominant degree)를 실증적으로 분석하고 있다. 선행연구에서는 지배적 디자인에 대한 측정방법은 구체적으로 제시되었지만 장기간에 걸쳐 데이터를 확보하지 못한 한계점으로 시간의 흐름에 따른 지배적 디자인(dominant design)의 실증연구가 제시되지 않았다. 따라서 본 연구에서는 연도별 디자인 변화 데이터를 확보한 후 휴대폰의 디자인 지배력(dominance)과 지배구조(structure change)가 어떻게 변했는지를 측정해 보았다. 측정결과, 휴대폰 디자인요소 중 바디형태(body form)와 모서리(edge)는 지배력(dominance)이 점점 증가하여 각각 직사각형으로 라운드 모서리로 집중화(convergence)되는 경향인 지배적 디자인요소를 가지고 있었고, 버튼방식(button type), 개폐방식(open type), DMB여부, 영상통화여부, 컬러조합, 바디컬러는 지배력이 높았다가 감소되면서 디자인수준(design levels)이 분산화(divergence) 되는 경향을 가지고 있었다. 이렇게 제품디자인요소의 지배력 정도를 측정함으로써 마케팅 관리자나 디자이너들에게 급변하는 시장 상황에서 제품전략을 수립하는데 도움이 될 것이다. 본 연구는 지배적 디자인에 대한 실증연구를 통해 신제품 개발시 지배적 디자인 등장에 대비한 성공적인 제품 개발의 가이드라인을 제공하는데 도움이 될 수 있다.

This paper explains modeling and analysis of RC-dominant wires for high-speed wireline transceiver design. A closed form formula derived from telegrapher's equation accurately describes a frequency response of an RC-dominant wire, yet it is simple and intuitive for designers to easily understand design trade-offs without a complex numerical equation solver. This paper explains how the model is derived and how it can help designers in example transceiver designs.

This paper addresses B-spline curve approximation of a set of ordered points to a specified toterance. The important issue in this problem is to reduce the number of control points while keeping the desired accuracy in the resulting B-spline curve. In this paper we propose a new method for error-bounded B-spline curve approximation based on adaptive selection of dominant points. The method first selects from the given points initial dominant points that govern the overall shape of the point set. It then computes a knot vector using the dominant points and performs B-spline curve fitting to all the given points. If the fitted B-spline curve cannot approximate the points within the tolerance, the method selects more points as dominant points and repeats the curve fitting process. The knots are determined in each step by averaging the parameters of the dominant points. The resulting curve is a piecewise B-spline curve of order (degree+1) p with $C^{(p-2)}$ continuity at each knot. The shape index of a point set is introduced to facilitate the dominant point selection during the iterative curve fitting process. Compared with previous methods for error-bounded B-spline curve approximation, the proposed method requires much less control points to approximate the given point set with the desired shape fidelity. Some experimental results demonstrate its usefulness and quality.

This study uses the concept of dominant design to identify the determinants for the emergence of a next-generation dominant electronic display. It employs multiple research methods with the participation of display experts, which combine case studies, an unstructured interview, and the Delphi method. The results show that based on technological innovation and market dominance, a next-generation dominant display is more likely to emerge as a result of technological competition between liquid crystal displays (LCDs) and organic light-emitting diodes (OLEDs). The findings emphasize that the importance of rapid technological innovation, including component and process innovations, and a competitive edge in manufacturing costs are important. The study sheds light on our understanding of dominance in an industry and market, and also provides strategic guidance for practitioners to establish a competitive strategy.

The purpose of this study is to analyze the effects of dominant brand, the quality variation among brands in the extension product category and the self-construals on consumer's attitude about extension products. The experimental design consist of three-way complex factors and 226 subjects participated for the study. The results showed that when there was fashion brand extension, whether or not there was an existing dominant brand in the extension product category, the quality variation among brands in the extension product category and the types of self-construals had a significant interaction effect on their favorableness and intention to purchase the extension products. Regardless of an existing dominant brand however, the group who had an interdependent self-construal showed higher favorableness and intention to purchase the extension products when the quality variation among brands in the extension product category was lower than when it was high, whereas the group who had an independent self-construal showed no significant difference of the favorableness and intention to purchase the extension products.

In this study, STS316L rolled at five rolling degrees were treated with two types of subzero temperatures for 10, 30, and 60 minutes, respectively, and the dominant frequencies of elastic waves was investigated. The dominant frequency was higher as the subzero temperature was lower and the subzero treatment time was longer at each rolling degree. On the other hand, the dominant frequency was higher as the elongation decreased. In the time-frequency analysis for subzero temperature and time of the specimen with a rolling degree of 33%, the dominant frequency was higher at a subzero temperature of -196℃ than -50℃ regardless of subzero treatment time.
