Learning Motivations for Chinese Unconventional FDI to Learn Innovativeness

배윤재,서민교,노태우 한국인터넷전자상거래학회 2018 인터넷전자상거래연구 Vol.18 No.5

This study focuses on the new motivation of Chinese outward foreign direct investment (FDI) toward developed countries by differentiating from previous studies on learning capabilities focused on external resources such as new knowledge and technology. In order to achieve success in competitive markets, Chinese firms are now more motivated to create their own values internally and to escape from being as copycat by learning a new innovative organizational culture. Throughout the Tencent case, investing on gaming industry by buying other game firms provides how this Chinese company is learning new corporate culture. Tencent could create their own values through two approaches. First way would be acquiring other gaming firms from culturally close to highly proximate culture, and second approach is from low level to higher level acquisition.

3-D Reconstruction of Human Face Using the Derivative Moiré Topography

배윤재,하병완,박지안,조춘식 한국광학회 2014 Current Optics and Photonics Vol.18 No.5

A new 3-D reconstruction algorithm for the human face is proposed using the derivative Moiré topography which ensures fast and robust reconstruction even for rough surfaces. The Moiré interference fringe pattern is initially obtained through the projection Moiré topography based on phase shifting, and then differentiated to provide a full unwrapped phase map for a human face. 2π ambiguity, which has been a chronically unsolved problem with Moiré topography, is successfully surmounted by differentiating the Moiré fringe patterns both in x- and y-directions when the object is located in the x-y plane. A real human face is used for verifying the proposed derivative Moiré topography. A human face of 4 different phase-shifted images taken in the fixed plane is almost fully reconstructed in 3-D format in 0.1 mm lateral resolution.

해외인수합병에서 인수기업의 흡수역량이 M&A 이후 기업성과에 미치는 영향: M&A경험과 전략적 자산의 조절효과를 중심으로

배윤재,서민교,노태우 한국국제경영학회 2019 國際經營硏究 Vol.30 No.2

This study argues that the absorptive capacity of companies is important in order to increase the corporate performance that companies ultimately take into consideration that there are limitations in behaviors to learn external knowledge of companies claiming from resource-based view(RBV). In this study, international M&A(mergers and acquisition) was selected as the act of accepting external information of companies. The study mainly focused on the fact that multinational corporations located in the US took overseas companies. The hypothesis of our study is that the higher the absorptive capacity of the firm, the higher the performance of the firm after absorbing the external knowledge. In addition, the hypothesis that acquiring firms can further improve their corporate performance after M & A suggests that controlling mergers and acquisitions of acquiring firms and strategic assets of target firms. This study suggests moderators (acquiring firm 's past M&A experience and acquired firm's strategic assets) as a hypothesis to further enhance corporate performance after M&A. In order to verify the hypothesis proposed in this study, 39,734 companies' M & A data were obtained from SDC Platinum. Among them, measurable enterprise information data were extracted from WRDS Compustat and finally selected 324 samples. The hypothesis was analyzed by linear regression under the control of the year in which the M&A was completed. According to results, both the past M&A experience and strategic assets as moderators including the relationship between the absorptive capacity and Tobin's Q were significant. Past M&A experiences of the acquirer, which has been examined in terms of the moderation effect, regulates the positive relationship between the absorptive capacity of the acquirer and the financial performance. The strategic asset of the target also has a positive relationship with the absorption capacity of the acquirer and the financial performance Respectively. The result of this study is that the multinational corporations as acquirers located in developed countries are attracted to accumulate the absorption capacity helpful in seeking overseas companies to be acquired in the future while it has an positive effect on the financial performance after M&A. 본 연구는 자원준거관점에서 주장하는 기업들의 외부 지식을 배우려는 행동에서는 한계점이 존재한다는 것을 고려하며 기업들이 최종적으로 지양하는 기업성과를 늘리기 위해서는 기업의 흡수역량이 중요하다는 점을 주장하고 있다. 기업들의 외부 정보를 받아들이는 행동으로 본 연구는 인수합병(M&A)을 선택하였으며, 미국 기업에서의 국내 및 해외로의 인수를 알아보았다. 본 연구에서는 기업의 흡수역량이 높을수록 외부 지식을 흡수한 후 기업의 성과가 더 높아질 것으로 보았으며, 이후 기업성과를 더 높일 수 있는 두 조절변수를 이용하였다. 본 연구가 제시하는 가설을 검증하기 위해 기업의 인수합병 데이터는 SDC Platinum에서 39,734개를 확보했으며 이 중, 측정 가능한 기업 정보 데이터는 WRDS Compustat에서 추출해 최종적으로 324개를 표본으로 선정하였다. 가설의 분석방법은 연도를 통제한 선형회귀를 시행하였으며 가설로 제시된 흡수역량과 Tobin’s Q의 관계를 포함한 과거 M&A 경험 및 전략적 자산의 조절효과 모두 유의한 것으로 나타났다. 조절효과로 살펴본 인수기업의 과거 M&A경험은 인수기업의 흡수역량과 재무성과의 긍정적인 관계를 조절하는 것으로 나타났으며, 피인수 기업의 전략적 자산도 인수기업의 흡수역량과 재무성과의 긍정적 관계를 조절하는 것으로 나타났다. 따라서 본 연구의 결과는 선진국에 있는 다국적 기업(인수자)이 흡수역량을 기르는 것은 향후 해외에 위치하는 피인수 기업을 물색하면서 도움이 되지만 실질적으로 재무성과에도 영향을 미치며, 과거 인수합병 경험과 피인수 기업이 가지는 전략적 자산의 크기에 따라 그 효과가 조절된다는 것을 발견하였다.

Behavior Intention of Consumers toward Self-driving Car Using TAM

배윤재,서민교,노태우 한국인터넷전자상거래학회 2017 인터넷전자상거래연구 Vol.17 No.5

This study uses the technology acceptance model(TAM) as its base to examine the future behavior intention of consumers toward self-driving cars. A Self-driving car is operated by multiple advanced systems which may be a combination of three-dimensional mapping, sensor technology, path planning and other complex technologies. In extending the TAM, issues of acceptability and perceived trust were included as external variables. The study utilized a survey of 149 South Koreans in their 20s and 30s, age ranges selected to catch up with fast-changing trends in technology. The results suggest that when people have acceptability of self-driving car is established, it leads to attention and behavior intention but the mediating effects of perceived ease of use toward perceived usefulness disappeared. In addition, when people perceive trust regarding a self-driving car, whether the car is perceived as useful or perceived as easy to use, their trust leads directly to behavior intention. However, the low coefficient level indicated for the concept that “learning to operate the self-driving car would be easy' leads to the conclusion that education materials should be provided to support easier learning.

SiC 인버터 기반 모터 구동 시스템의 절연 파괴 방지를 위한 dv/dt 필터 설계

최혜원,배윤재,강용진,박철현,이교범 대한전기학회 2024 전기학회논문지 Vol.73 No.1

This paper proposes design of dv/dt filter for insulation protection in SiC inverter-fed motor drive systems. The SiC inverter is subjected to voltage and current surges. It may cause additional losses in the motor, insulation failure, high bearing current, and electromagnetic interference. To mitigate these problems, a high value of gate resistance is placed at the gate driver; however, it introduces additional switching losses on the devices. In this paper, the filter is injected between the inverter and the motor system. The characteristics of each filter such as rising time, peak voltage, and dv/dt are analyzed to ensure the national electric manufacturers association (NEMA) standard. The proposed design scheme of the dv/dt filter is demonstrated by various experimental results.
