This paper examined the effect of innovation networks comprising research and development (R&D) collaboration on innovation performance of Korean pharmaceutical firms. As co-assigned patents and co-affiliated publications are common technical outcomes of successful R&D collaboration in the pharmaceutical industry, social network analysis technique was applied for analyzing innovation networks through patent and publication data. Results of Social network analysis indicated that a small set of highly innovative firms in the Korean pharmaceutical industry were actively involved in patenting and publishing. And the analysis of structural equation model found the followings: (1) R&D intensity significantly affected patenting, publication and new drug development, (2) the activity of patenting and publishing was positively related with the innovation performance measured by new drug development, and (3) R&D collaboration in terms of degree centrality of co-patent network played significant moderating roles on the relationships among R&D intensity, patenting, and new drug development. These findings are expected to be helpful to researchers as well as policy-makers to devise innovation-promoting policies in the Korean pharmaceutical industry. Discussions and limitations of the study are provided in the last part.

The problem of strategic R & D investment is formulate as a differential game model and solved explicity for a special case. It is shown that, at equilibrium, an increase in the intensity of market competition or a decrease in the role of technology transfer results in an increase in the initial rate of investment by competing tfirms. The increased initial investment rate may enhance the rate of technology development. This dynamic model can be used to propose non cooperative R & D investment policies in technologically competitive situation.

This study was conducted to determine the optimum amount of dried Alaska Pollock Therage chalcogramma roe (D-AP-R) for preparing garlic gochujang with D-AP-R. We investigated the optimal preparation of garlic gochujang with D-AP-R by proximate composition, taste, color, and odor measurements and sensory evaluation. The moisture, ash contents and water activity of garlic gochujang with D-AP-R decreased as the amount of D-AP-R increased, whereas other components, such as crude protein and lipid contents, taste value, yellowness of Hunter color, and odor intensity, increased as D-AP-R increased. According to the sensory evaluation results, garlic gochujangs with 10 and 15% D-AP-R were superior to garlic gochujang without D-AP-R (control) in terms of taste and overall acceptance but inferior in terms of fish odor. However, there was no difference in the sensual color of garlic gochujang with versus without D-AP-R. These results suggest that high quality garlic gochujang can be prepared by adding 10% D-AP-R. The total amino acid content of garlic gochujang with 10% D-AP-R was 11.81 mg/100 g, which was higher than that of the control (9.05 mg/100 g). The cholesterol content of garlic gochujang with 10% D-AP-R was 16.1 mg/100 g, which is below the acceptable daily cholesterol intake (300 mg/day).

This paper analyzes the price movements and the possibility of delisting by research and development intensity of firm which made technological innovation disclosure in the Korean stock market. The sample consists of firms listed on the KRX which made technological information disclosure between January 2002 and December 2014. The results are summarized as follows. The higher R&D intensity is observed for the delisted firms group. The logit regression result shows that the research and development intensity is a significant predictor of the possibility of delisting. This shows that exposure to the risk of delisting may increase as the proportion and uncertainty of intangible assets in the assets of individual firms increases. This empirical result is expected to serve as a good guide line for the stakeholders.

Purpose - This study investigates the effects of foreign investor ownership on firm innovation and the different stages of the firm innovation process for business group affiliation (affiliated firms) and nonaffiliated firms. Design/methodology - Research and development (R&D) intensity is used as a proxy for firm innovation. We use a sample of 7,655 firm-year observations of Korean listed firms from 2001 to 2015. To identify the distinct features of business group affiliation and how foreign investor ownership affects firm innovation, we divide the sample into affiliated and non-affiliated firms. Moreover, we classify total R&D expenditures as research and development expenditures. Findings - This study finds a positive relationship between foreign investor ownership and innovation in non-affiliated firms. However, the foreign investor ownership's role in facilitating firm innovation does not influence business group affiliation. Moreover, the results show that foreign investor ownership encourages firms to increase research expenditures, which is the amount spent in the early stages of a firm's R&D process. Originality/value - Existing studies have overlooked the distinct features of business group affiliation and the different characteristics of research and development expenditures. Thus, this study considers the distinct features of business group affiliation and investigates how foreign investor ownership affects different stages of R&D activities.

Among the atmospheric effect of laser propagation, the variations of the radiation transmittance by water aerosol evaporation have quantitatively been investigated. When the aerosol was exposed by a 1.07 ${\mu}m$ cw fiber laser, the increased amount of the transmittance variation was a maximum of 19.1% and the volume concentration variation of aerosol was observed as an increasing of laser intensity. Also, significant irregularity of refractive index was not found in the heated area during the continuous laser heating.

This research studies effect of FDA regulations in pharmaceutical industry on new drug development. System dynamics is implemented to demonstrate dynamic relationship between FDA regulations and R&D costs, firm's profits, sales. This research is focused on clinical trials of new medical entity process 50~60% portion of total development cost. Simulation results say that firm's profit is more sensitive to increasing the regulation than alleviating the regulation and effect of regulation policy make different result depending on the intensity of regulation and policy direction. Our simulation model provides the instrumental means for the policy makers and strategic decision in pharmaceutical industry.

The study addresses the analysis on the financial determinants of corporate research and development (R&D) expenditure in finance. Overall level of R&D spending was estimated as one of the top-tier on a global basis and a majority of the expenditure was invested by large domestic firms in private sector. Consequently, financial factors that influence R&D intensity were empirically tested in the first hypothesis by using conditional quantile regression model for firms listed in KOSPI stock market in the post-era of the global financial turmoil. Firms in the groups of high- and low-R&D intensity were statistically compared to detect financial differences in the second hypothesis which was accompanied by the test of multi-logit model that included firms without R&D outlay. Concerning the results of the hypothesis tests, R&D spending of the prior fiscal year, firm size, business risk and advertising expense overall showed statistically significant impacts to determine the level. As an extended study of [1] that had examined financial factors of R&D intensity at the macro-level, the results of the present study are anticipated to contribute to maximizing shareholders' wealth in advance or emerging capital markets, when applied to find an optimal level of R&D expenditure.

This research analyses the financial characteristics of corporate R&D intensity in the Korean capital market. It is important to pay greater attention to this subject, given the current situation of the shortage of core components domestically in Korea. Three hypotheses are postulated to investigate the financial factors of R&D investments for KOSDAQ-listed firms during the post-era of the global financial turmoil. By applying a conditional quantile regression (CQR) model, three variables included R&D intensity in the previous year (Lag_RD), the squared term of Lag_RD, and interaction between the high-tech sector and Lag_Rd, reveal significant effects on the current R&D ratio. Whereas more than half of the total variables show variable impacts between firms with higher and lower R&D intensity, only Lag_RD and squared term of Lag_RD were found to be significant. It is expected that these results may contribute to being financial catalysts for an optimal level of R&D expenditures, thereby maximizing firm value for shareholders in KOSDAQ-listed firms.
