In this study, we reviewed and analyzed the influencing factors of technology transfer performance in the previous studies (52 domestic journals and theses) and classified the various influencing factors into 6 top factors and 13 sub-factors based on the theoretical background. The study results of previous articles were analyzed by meta-analysis method so as to calculate the overall average effect size of influencing factors of technology transfer performance. As the result, the overall effect size (ESr) calculated through meta-analysis applying random effect model is .269, which corresponds to the medium effect size. By comparing effect sizes of influencing factors, the four(4) key influencing factors were also identified, which are 'number of researchers', 'dedicated organization', 'possess technology', and 'external cooperation'. The technology transfer performance are divided into three types: the number of technology transfers, technology transfer income, and other technology transfer performances. The major influencing factors of each type are derived through meta-analysis at the sub-category level. As moderator variables, the paper type and the data type were analyzed but no significant results were obtained. Since this research is limited to the technology transfer, it is necessary to carry out the study related to the influencing factors on the technology commercialization as following study.

In a global software development project, knowledge transfer between a corporate headquarter and offshore development sites is considered to be important for effective software development. This article presents empirical research that investigates factors influencing knowledge transfer in global software development. The factors evaluated in this study are: 1) quality of communication infrastructure, 2) quality of partnership and 3) types of governance mechanism. Questionnaires were collected from offshore development sites in Mauritius. While the quality of both the partnership and communication infrastructure were found to be determinants to knowledge transfer, hierarchical governance had a negative impact on knowledge transfer. Although the results are similar to the previous studies done within an organizational boundary, implications of the results are far different due to the geographical distance among offshore locations. Future research is called for to investigate the relationships between governance type and knowledge transfer.

The development of information technologies has contributed on-line training as one of important education methods. On-line training in firms, which is similar to e-learning or virtual education, provides trainees with more education opportunities in diverse ways. It has developed a range of innovative services with a one-stop solution of education within the electronic sector. Also under the on-line training environment, trainees can undertake customized training packages at anytime and any places. Moreover, information technology allows both the trainers and other trainees to be decoupled in any of the elements of tune, place, and space. Two research questions are investigated : what are the determinants affecting the on-line training effectiveness and how those variables affect the two aspects of training effectiveness: learning performance and transfer performance. Based on the previous literature conducted on the traditional training environment, the determinants of training effectiveness are derived. Eight hypotheses are developed based on literature reviews and tested by questionnaires survey data. The collected data have been analyzed by LISREL. It is found that the relationship between individual, organizational and on-line site design variables and training effectiveness (learning and transfer) are significant. The contribution and limitations of this research are also discussed with future studies.

The aim of this paper is to address the factors that influence R&D performance of the Korea Institute of Science and Technology (KIST), the representative government-supported research institute in Korea, through an empirical case study. Using the KIST R&D project data from 2004 to 2008, we investigate the determinants of R&D performance through a logistic regression analysis, and compare the results with the survey data we collected from researchers. Our results indicate that total budget, high rate of temporary researchers, and the outcome of the research director's past publications affect publishing performance, while the size of equipment, materials expenditure, and whether the research is outsourced or not affect patent registration performance and technology transfer performance. Contrary to expectations, major factors of publishing performance and that of patent performance are different respectively, and even the results of the survey data we collected from researchers show the difference. Accordingly, the findings of our study suggest the need for research institutes to consider facilitating communication with researchers and enhancing research policy analysis for improving R&D performance.

Hadron therapy, such as carbon and helium ions, is increasingly coming to the fore for the treatment of cancers. Such hadron therapy has several advantages over conventional radiotherapy using photons and electrons physically and clinically. These advantages are due to the different physical and biological characteristics of heavy ions including high linear energy transfer and Bragg peak, which lead to the reduced exit dose, lower normal tissue complication probability and the increased relative biological effectiveness (RBE). Despite the promising prospects on the carbon ion radiation therapy, it is in dispute with which bio-mathematical models to calculate the carbon ion RBE. The two most widely used models are local effect model and microdosimetric kinetic model, which are actively utilized in Europe and Japan respectively. Such selection on the RBE model is a crucial issue in that the dose prescription for planning differs according to the models. In this study, we aim to (i) introduce the concept of RBE, (ii) clarify the determinants of RBE, and (iii) compare the existing RBE models for carbon ion therapy.

New companies expecting market penetration by adopting technology commercialization process could face high uncertainty and constraints. In particular, ICT-based firms that enter competitive markets must deal with more complex situations. Although in-depth research has been done to solve the problem, there is still a lack of understanding of how startups' technology commercialization process is successful. To discuss the issue, this paper presents the technology commercialization model and determinants.(policy, finance, work team, organizational culture, overcoming the difficulties etc.) the suitability of the framework. From this analysis it emerged that the sustainability of organizational capabilities is as important as the adherence to the technology commercialization process for companies. As the organizational capacity has decreased, the driving force for technology commercialization has weakened. Therefore, the technology commercialization process does not guarantee the success of the market entry but is understood as a means of market access. If the organizational capacity is not strengthened, there is no successful technology commercialization process.

This research performed the empirical test for the effects of learning transfer on perceived usefulness, perceived ease of use, self-efficacy and work environment using 390 employees who have experienced e-learning in domestic and foreign companies. Analyzed the mediating effects of self-efficacy and work environment in addition to direct effect of each factor on learning transfer. The results showed that perceived usefulness and perceived ease-of-use of e-learning learner had a positive(＋) effect on self-efficacy and a positive influence on supervisor and peer support and organizational climate. Self-efficacy showed a positive effect on learning transfer, and supervisor support, peer support and organizational climate had a positive influence on learning transfer as well. Perceived usefulness also had a positive effect on learning transfer. However, perceived ease-of-use had no significant effect on learning transfer. As a result of the mediating effect analysis, self-efficacy and work environment were analyzed to have mediating effects between perceived usefulness, perceived ease of use, and learning transfer. The implications of this study are as follows. First, this study designed a new research model that reflects factors influencing the effect of learning transfer on acceptance of e-learning that is common in corporate education. It has derived a research model of perceived usefulness and perceived ease-of-use, which were used as mediating variables for external characteristics factors, as independent variables, using self-efficacy and work environment as mediating variables, which were studied as external factors. Second, most of the studies on technology acceptance model and learning transfer are conducted in a single country. The reliability was enhanced by testing the study models using different samples from 26 countries. Third, perceived usefulness and ease-of-use in existing studies have been considered as key determinants of acceptance intention and learning transfer. This study explored the mediating effects of learner and environmental factors on the accepted information technology and strengthened and supplemented the path of learning transfer of perceived usefulness and ease-of-use. In addition, based on the sample analysis of various countries used in this study, it is expected that future international comparative studies will be possible.

Mechanisms underlying the impacts of interactions between carbon nanoparticles (CNPs) and ionic liquids (ILs) on the physicochemical behavior of CNPs need to be more full worked out. This manuscript describes a theoretical investigation at multiple levels on the interactions of fullerene $C_{60}$ with 21 imidazolium-based ILs of varying alkyl side chain lengths and anionic types and their impacts on $C_{60}$ dispersion behavior. Results show that ${\pi}$-cation interaction contributed to mechanism of the $C_{60}$-IL interaction more than ${\pi}$-anion interaction. The calculated interaction energy ($E_{INT}$) indicates that $C_{60}$ can form stable complex with each IL molecule. Moreover, the direction of charge transfer occurred from IL to $C_{60}$ during the $C_{60}$-IL interaction. Quantitative models were developed to evaluate the self-diffusion coefficient of $C_{60}$ ($D_{fullerene}$) in bulk ILs. Three interpretative molecular descriptors (heat of formation, $E_{INT}$, and charge) that describe the $C_{60}$-IL interactions and the alkyl side chain length were found to be determinants affecting $D_{fullerene}$.

A Fe-Ni Bainitic steel as a weathering steel application was developed by combining its excellent mechanical properties and corrosion resistance in maritime environments. Nickel concentration (0.4-3 wt%) and inverted austempering multi-step (IAM) process were primary determinants of the microstructure of the Fe-Ni Bainitic steel. The initial austempering steel was performed at 300 ℃ for 600 seconds to obtain a partly bainitic transformation. The steel was heated again for 1800 s at 450 ℃. The microstructure was comprised of ferrite, a blocky martensite/austenite island, and a homogeneous lath-shape bainite structure with widths ranging from 4.67 to 6.89 ㎛. The maximum strength, 1480 MPa, was obtained with 3 wt% nickel. In this study, corrosion behavior was investigated utilizing potentiodynamic and electrochemical impedance spectroscopy (EIS) tests. A higher nickel content in Fe-Ni Bainitic steel refined the grain size, improved the bainite fraction, lowered the corrosion rate to 0.0257 mmpy, and increased the charge transfer of film resistance to 1369 Ω.

In recent years, universities, with their intellectual properties and human resources, become main drivers for technology transfer. Universities in Korea have various organizations to support the technology transfer and commercialization. Among them, a technology holding company plays the critical role to successfully implement the task. Nonetheless, the performance of the technology holding company is well below the expectation of industry, government and universities themselves. The lack of expertises and experience together with the ill-suited government policies could be attributable to the observed under performance. More recently, however, the technology holding company acts as an accelerator or venture capital to search and fund promising start-ups. The university venture capital thus transforms a traditional university into an entrepreneurial university. Focusing on the role of the technology holding company as an accelerator or venture capital, the paper analyzes the characteristics of the university venture capital and the invested start-ups. The performance of the university venture capital is measured and the determinants of the performance are empirically tested. The results show that the co-investment of outside investors and the support of government program, known as Tech Incubator Program for Startup Korea, yields the highest performance. The result indicates that the coordination of the university venture capital, industry and government is the key to the success of early start-ups. The paper is the first to analyze the performance of the university venture capitals in Korea and thus contributes to the literature.
