  • 본 연구는 공공연구기관 연구자 관점에서 창업성공가능성 결정요인의 순효과와 결합효과를 분석하는데 목적이 있다. 이를 위해 기존 문헌을 기초로 연구자의 창업성공가능성 결정요인을 검토하고, 창업성공가능성 결정요인간의 개념적인 관계를 설정하였다. 자료수집은 대덕연구 개발특구내 공공연구기관 연구자를 대상으로 설문조사를 통해 이루어졌으며, 총 114개의 자료가 수집되었다. PLS 분석방법은 창업성공가능성 결정요인의 순효과를 분석하기 위해 사용되었고, fsQCA는 창업성공가능성 결정요인의 결합적 효과를 분석하기 위해 사용되었다. PLS 분석결과에서 기술사업화가능성과 창의적 자기효능감은 창업성공가능성에 독립적으로 유의적인 정의 영향을 미치는 것을 발견하였다. 반면, 기술사업화역량, 정보접근성 및 네트워크는 창업성공가능성에 유의적인 영향을 미치지 못한다. 한편, fsQCA결과에서 기술사업화가능성, 기술사업화역량 및 창의적 자기효능감이 높으면 창업성공가능성이 높아지는 결합적 효과를 확인하였다. 특히, 공공연구기관 연구자의 창의적 자기효능감은 창업성공가능성에 영향을 미치는 핵심조건인 것으로 나타났다. 이러한 연구결과는 공공연구기관 연구자의 창업성공가능성 결정요인을 이해하는데 학술적 시사점을 제공한다.

  • Forecasting probability or likelihood of technology development success has been a crucial factor for critical decisions in technology management such as R&D project selection and go or no-go decision of new product development (NPD) projects. This paper proposes an analytic network process (ANP) approach to forecasting of technology development success. Reviewing literature on factors affecting technology development success has constructed the ANP model composed of four criteria clusters : R&D characteristics, R&D competency, technological characteristics, and technological environment. An alternative cluster comprised of two elements, success and failure is also included in the model. The working of the proposed approach is provided with the help of a case study example of MRAM (magnetic random access memory) technology.

  • The likelihood ratio, logistic regression and artificial neural networks methods are applied and verified for analysis of landslide susceptibility in Yongin, Korea using GIS. From a spatial database containing such data as landslide location, topography, soil, forest, geology and land use, the 14 landsliderelated factors were calculated or extracted. Using these factors, landslide susceptibility indexes were calculated by likelihood ratio, logistic regression and artificial neural network methods. Before the calculation, the study area was divided into two sides (west and east) of equal area, for verification of the methods. Thus, the west side was used to assess the landslide susceptibility, and the east side was used to verify the derived susceptibility. The results of the landslide susceptibility analysis were verified using success and prediction rates. The v erification results showed satisfactory agreement between the susceptibility map and the exis ting data on landslide locations.

  • With various success stories of crowdfunding, government's establishment of crowdfunding act, and expected rapid growth of crowdfunding market, the potential ripple effect of crowdfunding on our society is anticipated to be enormous. This study investigates the influential factors and their impacts on the likelihood of project success in donation-based crowdfunding through the DonorsChoose case. The authors analyze the characteristics of project creator, characteristics of project, and behaviors of project participants in relation to the success or failure of the corresponding project. Consequently, the authors found that participants of donation-based crowdfunding exhibit altruistic behaviors and obtained the following specific results: First, donation participation and social capital of the project creator, and marginal help utility of receivers positively affect the success of project. Second, experience of past project creation of the project creator negatively affects the success of project. Third, past donations of the project creator to others' projects, when not appropriately signaled like on the DonorsChoose platform, may not exert a positive influence on the success of project and the reciprocity principle may not work.

  • When we construct an interval estimate of two independent proportions with rare events, the standard approach based on the normal approximation behaves badly in many cases. The problem becomes more severe when no success observations are observed on both groups. In this paper, we compare two alternative methods of constructing a confidence interval of the difference of two independent proportions by use of simulation. One is based on the profile likelihood and the other is the Bayesian probability interval. It is shown in this paper that the Bayesian interval estimator is easy to be implemented and performs almost identical to the best frequentist's method -the profile likelihood approach.

  • This study explores how the technology commercialization process leads to either success or failure after transfer from PROs to SMEs by conducting a binomial logistic regression analysis. We found that the more additional development a firm implements on the transferred technology, the more likely the commercialization is to fail. The higher number of alternative technology and bigger market risk are associated with a greater likelihood of failure. On the other hand, the existence of complementary technology, the degree of cooperation with the technology provider, the size of the target market, the willingness of the CEO, and the funding availability are known to have positive effects on the success of technology commercialization. In addition, the case studies we conducted from the sample companies demonstrated that "market uncertainty," "technological issues depending on the technology-specific characteristics," and "a lack of funding capability" are some of the causes for failure of technology commercialization.

  • The IT implementation literature suggests that various implementation factors play critical roles in the success of an information system; however, there is little empirical research about the implementation of data warehousing has unique characteristics that may impact the importance of factors that apply to it. in this study, a cross-sectional survey investigated a model of data warehousing success. Data warehousing managers and data suppliers from 51 organizations completed paired mail questionnaires on implementation factors and the success of the warehouse. The results from a regression analysis of the data identified relationships between the system quality and data quality factors and perceived net benefits. It was found that management support and resources help to address organizational issues that arise during warehouse implementations, resources, user participation, and highly-skilled project team members increase the likelihood that warehousing projects will finish on-time, on-budget, with the right functionality; and diverse, unstandardized source systems and poor development technology will increase the technical issues that project teams must overcome. The implementation's success with organizational and project issues, in turn, influence the system quality of the data warehouse; however, data quality is best explained by factors not included in the research model.

  • Purpose: This study examined a comprehensive model for assessing the success probability of electric vehicle (EV) commercialization in the Korean market. The study identified three risks associated with successful commercialization which were technology, social, policy, environmental, and consumer risk. Research design, methodology: The assessment of the riskiness was represented by a Bayes belief network, where the probability of success at each stage is conditioned on the outcome of the preceding stage. Probability of success in each stage is either dependent on input (i.e., investment) or external factors (i.e., air quality). Initial input stages were defined as the levels of investment in product R&D, battery technology, production facilities and battery charging facilities. Results: Reasonable levels of investment were obtained by expert opinion from industry experts. Also, a survey was carried out with 78 experts consisting of automaker engineers, managers working at EV parts manufacturers, and automobile industry researchers in government think tanks to obtain the conditional probability distributions. Conclusion: The output of the model was the likelihood of success - expressed as the probability of market acceptance - that depended on the various input values. A model is a useful tool for understanding the EV industry as a whole and explaining the likely ramifications of different investment levels.
