This study proposes a three-stage model of R&BD performance which captures commercialization outcomes as well as conventional R&D performance. The model is composed of three factors : inputs (R&D budgets and researchers), outputs (patents and papers), and outcomes (technical fees, products sales, and cost savings). Three stages are defined for each transformation process between the three factors : efficiency stage from input to output (stage 1), effectiveness stage from output to outcome (stage 2), and productivity stage from input to outcome (stage 3). The performance of each stage is measured by data envelopment analysis (DEA). DEA is a non-parametric efficiency measurement technique that has widely been used in R&D performance measurement. We measure the performance of 171 projects of 6 public R&BD programs managed by Seoul Business Agency using the proposed three-stage model. In order to provide a balanced and holistic view of R&BD performance, the R&BD performance map is also constructed based on performance of efficiency and productivity stages.

Research and Development(R&D) investment is an issue of central importance in any economy. In this paper we analyze the relationship between R&D spillovers and trade-related variables, using a two-stage model where duopolists simultaneously decide on R&D in the first stage and engage in Cournot competition in the second stage. We characterized and compared the free-trade and trade-restriction R&D equilibrium in a two-stage game of R&D investment followed by Cournot market competition. We also assessed the impact of varying the R&D spillover on the equilibrium outcomes and tariff. We showed for both free trade and protection cases that there exists a unique symmetric solution(subgame perfect Nash equilibrium). As the solution, while analytical, cannot be stated in closed form, we resorted to numerical experiments to investigate the equilibrium results. Our estimates indicate for both free trade and protection cases that the level of R&D investment and the rate of R&D expenditure decrease as the degree of R&D spillovers increases, and that there is an inverse relation between the degree of R&D spillovers and level of protection. The latter implies that the larger the degree of R&D spillovers, the lesser the level of protection.

This study explores the role of knowledge sharing activities among team members and performance in R&D setting. Knowledge sharing activities are classified into two : Knowledge sharing activity within/outside team. And the relationships between the knowledge activities and R&D performance are also examined according to three R&D stages : basic, applied, and developmental research. A empirical study was conducted at a research institute of large company that leads the advanced research and development of the domestic chemical industry. Data was collected 292 copies out of 500 copies (Response rate 58.4%). The result indicated that knowledge sharing within and outside the team has a positive effect on R&D Performance. In particular, knowledge sharing within the team has a greater effect on R&D outcomes in basic research stage. Knowledge sharing outside the team has a greater effect on R&D outcomes in the development research stage. In the R&D organization, it is important that members of the team are well-connected and understanding each other, but they should encourage positive relationships with external members of the team. Depending on the R&D field of the team, the basic research field should concentrate more on knowledge sharing within the team, while the development research field should focus more on knowledge sharing outside the team.

In acquiring and transferring a superior knowledge assesing the intermediate result value of a competitive R&D project is very important for a firm engaging in R&D. Most existing literatures on R&D evaluation are concerned with project selection and resource allocation. In this paper the stage of an R&D project is classified into research, exploratory development, and development. And a model is suggested which evaluates the intermediate result value before completion of development stage under duopoly and oligopolistic competition. Assessed value of the intermediate result transferred to the next tier company can be used as a minimum acceptable price to the inventor when more advanced knowledge acquired through R&D is transferred to the next tier one. The model suggested is composed of structural variables including research cost, success rates, potential profits, discount rate degree of competition. By using exponential distribution for invertion process time in each stage, we derive a formula that can assess the value of the intermediate result, and we demonstrate how the model can be applied to a competitive R&D situation through an example.

Purpose - Major countries in the world continue to grow up without employment by the economy opening, more investment in foreign countries and technical innovation. Nevertheless, SMEs have job creation continuously. As this result, support for SMEs that is the source of job creation has increased attention. However, previous research between SMEs and job-creating is limited to the job creation effect of comparing with large companies, and R&D investment effect including government support. Also, many research provides the different result of correlation with technology innovation and job creation. Therefore, previous research has insufficient to explain job creation by which in the technology commercialization stage and the job-specific workforce. Research design, data, and Methodology - This study investigated the impact of customized R&D support upon job creation by using questionnaires of SMEs R&D service of K-Institution from 2009 to 2013. In detail, we analyzed the relationship between the technology commercialization stage and the usefulness of customized R&D support. Also, we added the analyzed the relationship between the usefulness of customized R&D support and the job-specific workforce. Results - Research result, Job creation had a significant relation to the usefulness of customized R&D support in product design stage and mass production stage. Also, R&D worker and production worker correlated with the usefulness of customized R&D support. These results indicate the importance of hiring R&D workers and production workers at the higher technology readiness. Conclusions -Therefore, this study suggests some implications for the government's SMEs support policy and the solve employment problems such as youth unemployment.

The purpose of this study is to develope a stage management model for R&D projects using expert system in order to evaluate the successful accomplishment and diagnose the success level of projects at each development stage. Constructing this model, we classified the development projects for electronic parts, and designed the basic system structure through causation analysis between the factors of success influence and R＆D process. We gathered the input data of expert system by enquete survey, and used ID3 algorithm in order to extract the reasoning rule.

This paper empirically evaluates the effects of regional and industrial R&D on the performances of individual firms in two separated stages: (1) the stage of technological outcome from R&D and (2) the stage of economic outcome from technological outcome. Technological spillovers are separated from negative congestion effects through the stage-specific estimation. The firm-level Korean Innovation Survey data merit in coping with the endogeneity problem inherent in the estimation of spillovers. The estimation results show that: (1) there exist significant R&D spillovers both in regional and industrial dimensions, (2) the hypothesized technological spillovers and economic congestion effects are both in effect, and (3) firms with smaller individual R&D investments show greater spillovers.

Korean native cattle (Hanwoo) have a good capacity to produce heavily marbled meat of high value. The intramuscular fat in Hanwoo is known to be deposit from 12 months of age by degree of slightly visible and significantly developed in 28 months of age. Lipogenesis gene expression profiling in longissimus dorsi at early and late fattening stage will be helpful to understand the mechanism of intramuscular fat deposition in skeletal muscle. Therefore, we analysed the gene expression patterns of six genes related lipid metabolism (FABP4, GLUT4, LPL, ACC, ACL and SCD) between early and late fattening stage. The mRNA expression of FABP4 at late fattening stage (27 months old) was higher about 3.0 fold than at early fattening stage (12 months old) in each three individuals of Hanwoo. However, GLUT4 mRNA expression was not different at late fattening stage compared with at early fattening stage. On the other hand, The expression patterns of LPL, ACC, ACL and SCD genes related lipid metabolism were significantly over-expressed about 3.5 fold, 2.7 fold, 3.7 fold and 7.5 fold at late fattening stage, respectively. Thus, these results suggested that lipogenesis in skeletal muscle at late fattening stage is due to increasing uptake of fatty acid by FABP4 and lipogenesis gene expression such as LPL, ACC, ACL and SCD.

Defense R&D is an essential investment for the national security. Recently our nation has also begun to initiate a number of defense R&D projects. As a lot of fund and resources are allocated to these projects, we need to identify which projects to initiate and then how to manage these projects well. Though there have been a number of studies on R&D projects in commercial sector, there are only a few studies in defense R&D sector. Moreover, these existing defense R&D studies mainly deal with the former issues, which are occurring at the stage of project planing. We are more concerned with project management issues, such as how to manage projects that had already been evaluated to undertake at the planning stage. Specifically our study aims to identify project management factors leading to the success of defense R&D projects. Results of the empirical analysis indicate that management support, user-driven requirements management, and project planning capability are key elements for project performance.

In this paper, a two-stage and top-down approach of mid-term and long-term R&D planning of public corporation is proposed to incorporate some characteristics of public corporation and to overcome the complexity of the real world planning. Unlikely to R&D planning of private company, the total investiment size of public corporation is institutionally determined. A top-down approach is developed to adopt this feature. The proposed approach has two stages to overcome the complexity. In the first stage, we develop a plan for R&D area by adopting the business area and the public role of corporation. In the second stage, we develop the detailed plan within each area. The proposed approach is applied to develop the mid-term and long-term R&D plan of Korea Gas Corporation.
