LAU Ka Wing,Erik Baark,William L.W. Lo,Naubahar Sharif 기술경영경제학회 2013 ASIAN JOURNAL OF TECHNOLOGY INNOVATION Vol.21 No.2

It is widely recognized in the theoretical literature that firms need to use both internal andexternal sources of innovation to gain a competitive advantage. However, although it isassumed that internal and external sources of innovation have distinct relationships withfirm capabilities, it is not clear how various innovation sources affect such capabilities, orhow or to what extent such relationships affect product competitiveness. This paperexamines the effect of diverse sources of innovation on a firm’s technological innovationcapabilities and the extent to which such capabilities mediate the improvement of productcompetitiveness. Based on a survey of 200 manufacturing firms in Hong Kong and the PearlRiver Delta region, we identify internal departments as a major source of innovation forimproving a range of firm capabilities. Acquiring disembodied technology improveslearning, resource allocation and organizing capabilities, whereas acquiring embodiedtechnology enhances learning and manufacturing capabilities. We use a hierarchicalregression analysis to demonstrate that some sources of innovation, such as internaldepartments, can lead directly to superior product competitiveness, whereas innovationsacquired through conferences and competitors contribute to competitiveness through themediation effects of resource allocation, marketing and organizing capabilities.

Topologies of Active-Switched Quasi-Z-source Inverters with High-Boost Capability

Ho, Anh-Vu,Chun, Tae-Won The Korean Institute of Power Electronics 2016 JOURNAL OF POWER ELECTRONICS Vol.16 No.5

This paper proposes both an active-switched quasi-Z-source inverter (AS-qZSI) and an extended active-switched qZSI (EAS-qZSI), which are based on the classic qZSI. The proposed AS-qZSI adds only one active switch and one diode to the classic qZSI for increasing the voltage boost capability. Compared with other topologies based on the switched-inductor/capacitor qZSI, the proposed AS-qZSI requires fewer passive components in the impedance network under the same boost capability. Additionally, the proposed EAS-qZSI is designed by adding one inductor and three diodes to the AS-qZSI, which offers enhanced boost capability and lower voltage stress across the switches. The performances of the two proposed topologies are verified by simulation and experimental results obtained from a prototype with a 32-bit DSP built in a laboratory.

This paper proposes a quasi Z-source AC-AC converter with the low DC voltage distribution capability operating as a power electronic transformer. The proposed system has configuration that the input terminals of two quasi Z-source AC-AC converters are connected in parallel, also their output terminal are connected in series. Simple control method of duty ratio was proposed for the in phase buck-boost AC voltage mode and the DC output voltage control. DSP based experiment and PSIM simulation were performed. As a result, the PSIM simulation results were same with the measured results. By controlling the duty ratio under the condition of 100 [Ω] load, quasi Z-source AC-AC converter could buck and boost the AC output voltage in phase with the AC input voltage, and the same time, the constant DC voltage could be output without affecting the AC output characteristics. And, the DC output voltage 48[V] was constantly controlled in dynamic state in case while the load is suddenly changed (50 [Ω]→100 [Ω]). From the above result, we could know that the quasi Z-source AC-AC converter can act as a power electronic transformer with a low DC voltage distribution capability.

An Exploratory Study on Determinants Affecting R Programming Acceptance

Jennifer Rubianogroot,Su Hyeon Namn 대한경영정보학회 2018 경영과 정보연구 Vol.37 No.1

R 프로그래밍 시스템은 인터넷을 통해 개방적이고 무료로 제공이 된다. R 환경은 헌신적이고 독자적인 사용자 그룹이 제공하는 다양한 함수가 포함되는 라이브러리에 의해 그 기능이 지속적으로 풍부해지고 다양해지고 있다. R의 사용은 조직에서의 빅데이터 분석이 점차 도입되면서 다양한 데이터 형태의 데이터 조작과 데이터 분석처리가 요구되면서 점차 채택되기 시작하였다. 그러나 R 수용에 대한 연구는 아직까지 존재하지 않고 있다. 본 연구는 교육환경의 사용자가 R을 수용하는데 미치는 인지변수를 식별하고, 그들간의 관계를 규명하고자 한다. 기존의 기술수용모형에 주관적 규범과 소프트웨어 역량을 추가한 확장된 R 수용모델을 제안하고, 경로분석을 통하여 가설을 검정하였다. 사용의도에 정의 영향을 미치는 변수는 주관적 규범, 지각된 편리성, 지각된 유용성으로 밝혀졌고, 지각된 유용성은 주관적 규범, 소프트웨어 역량, 그리고 지각된 편리성으로부터 영향을 받는 것으로 나타났다. 본 연구가 이전 연구와의 주요 차이점은 대상 시스템이 독립적인 시스템이 아니고, 또한 시스템은 정적이고 개발이 확정된 상태가 아닌 진화하고 오픈소스 시스템을 대상으로 했다는 것이다. 또한 R 환경은 플랫폼으로서, 다양한 통계분석, 빅데이터분석, 그리고 시각화가 가능한 시스템이다. 우리는 TAM (Technology Acceptance Model)을 적용하여 R플랫폼에 대한 사용자의 수용에 영향을 주는 변수를 식별하고 인과관계를 처음으로 시도하였다. 또 다른 기여도는 기존의 TAM모형에 주관적 규범과 소프트웨어 역량 개념을 추가한 확장된 모형을 식별한 것이다. 본 연구결과는 통계나 빅데이터 분석 패키지 도입 계획이 있는 대학이나 기업체에 시사점을 제공할 수 있을 것이다. 그러나 분석에 사용된 표본의 수가 적고, 표본이 모집단을 대표할 수 있다는 근거가 약해 제안된 모델의 신뢰성 및 타당성이 상대적으로 미흡하다고 할 수 있을 것이다. 따라서, 향후 연구에서는 확정적 연구를 위해서는 이와 같은 문제점에 대한 보완이 필요하다고 판단된다. R programming is free and open source system associated with a rich and ever-growing set of libraries of functions developed and submitted by independent end-users. It is recognized as a popular tool for handling big data sets and analyzing them. Reflecting these characteristics, R has been gaining popularity from data analysts. However, the antecedents of R technology acceptance has not been studied yet. In this study we identify and investigates cognitive factors contributing to build user acceptance toward R in education environment. We extend the existing technology acceptance model by incorporating social norms and software capability. It was found that the factors of subjective norm, perceived usefulness, ease of use affect positively on the intention of acceptance R programming. In addition, perceived usefulness is related to subjective norms, perceived ease of use, and software capability. The main difference of this research from the previous ones is that the target system is not a stand-alone. In addition, the system is not static in the sense that the system is not a final version. Instead, R system is evolving and open source system. We applied the Technology Acceptance Model (TAM) to the target system which is a platform where diverse applications such as statistical, big data analyses, and visual rendering can be performed. The model presented in this work can be useful for both colleges that plan to invest in new statistical software and for companies that need to pursue future installations of new technologies. In addition, we identified a modified version of the TAM model which is extended by the constructs such as subjective norm and software capability to the original TAM model. However one of the weak aspects that might inhibit the reliability and validity of the model is that small number of sample size.

The Effects of the Integrated Communication Mix on the Customer Trust for On-line Business; focused on e-Mail Communication

정상익,황민우 국제e-비즈니스학회 2007 e-비즈니스 연구 Vol.8 No.4

On-line shopping mall is to continuously send email to customers who make permission to receive e-mail. Unless the customers get out of membership or refuse to receive e-Mail, they will receive continuously messages. Such a method of sending message can make aversion of customers and weaken the effectiveness of communication. Considering this, the methodology of communication should be set up with checking the response on customers who receive e-mails. This research is on how we can increase the effectiveness of communication with the ways of construction of communication mix. This research verified that, according to the consistency level of components in communication mix, which comprise High Integration and Low Integration, affect the trust level of customers. Besides, This research confirm the adjustment effect in proportion to the loyalty of message receiver, and also the relation between the control effect on customer trust and increase of number of message in viewpoint of ‘numbers of message source.’ As a result, the trust level of customer is enhanced as the level of communication integration is higher. Regarding the control effect, the loyalty of customer is direct proportion to the trust level of customers, while the number of source of messages is inverse proportion to the trust level of customers. Besides such verification analysis results, diverse interpretations, theoretical and practical implications were discussed and future research directions were suggested.

박연진(제1저자) ( Yeon Jin Park ),송재용(교신저자) ( Jae Yong Song ),( Kazuhiro Asakawa ) 한국국제경영학회 2016 國際經營硏究 Vol.27 No.1

This paper examines the factors that influence innovative performance of overseas R&D subsidiaries by analyzing data from overseas R&D laboratories of Japanese multinational corporations. After classifying the capabilities of the overseas R&D labs as sourcing capabilities and combinative capabilities, this paper analyzed the effects of such capabilities on innovative performance. This paper focused on the impacts of the two types of combinative capabilities associated with the abilities to combine and utilize knowledge from different knowledge sources on subsidiary innovative performance. This paper also explored the moderating role of combinative capabilities and autonomy. Statistical findings from negative binomial regressions with integrated data from surveys and patent data of overseas R&D laboratories of Japanese MNCs revealed that combinative capability related to combined knowledge from home country, host country, and other countries had a positive impact on the quality of subsidiary innovation. Additionally, the results also indicated that both sourcing capability and autonomy have a positive impact on innovative performance on an overseas R&D subsidiary. Furthermore, the degree of combinative capability related to utilizing knowledge from home country, host country, and other countries served to strengthen the positive relationship between sourcing capability and the innovative performance of an overseas R&D subsidiary.

Analysis of the Open Source Software Sector in China

( Qiong Wu ),( Krzysztof Klincewicz ),( Kumiko Miyazaki ) 기술경영경제학회 2006 Journal of Technology Innovation Vol.14 No.2

The paper describes the status and context of the Chinese Open Source Software (OSS) industry and ecosystem based on the analysis of the components of the China OSS Promotion Union. The analysis involves comparisons of several main Chinese developers of Linux operating system and makers of open source counterpart of the popular Microsoft Office package as well as several main Chinese OSS communities. Comparisons concern the technological and business aspect. The findings reveal peculiarities of the divergence of innovative activities of Chinese companies, as well as indicate that the strong government support may at the same time limit the technology selection under rigid competition, especially as foreign open source companies are found to be more focused on hobbyist developers and are able to maintain larger independent communities. Implications of the paper include the need to coordinate global development efforts and adjust science & technology policies in order to stimulate both the development and the diffusion of open source among Chinese companies and individual hobbyists.
