  • In earlier investigations, seeds of Perilla frutescens(L.) Britt. cv. Chookyoupjaso were irradiated with 200 Gy gamma ray to generate mutagenesis. The aim of this study is to investigate the effects of a hexane extract from Perilla frutescens (L.) Britt. cv. Chookyoupjaso mutant 45 on the actions of anti-inflammatory activity on inducible nitric oxide synthase, and an identification of the major active compound. The hexane extract from P. frutescens exhibited activity of inhibition of a NO production ($IC_{50}$, $295.1{\mu}g\;ml^{-1}$). The hexane extract was further divided into subfractions by silica-gel chromatogarphy. Inhibition of the NO production by various fractions was assayed in LPS-stimulated RAW 264.7 cells. Among the seven fractions, the 5th fraction was the most effective ($IC_{50}$, $19.5{\mu}g\;ml^{-1}$). The 5th fraction suppressed the expression of protein of iNOS in LPS-induced RAW 264.7 cells, and GC/MS analyses showed that isoegomaketone is a major bio-active compound in the 5th fraction. The result indicated that isoegomaketone has a good potential to be developed as an anti-inflammation agent.

  • For the implementation of innovative products or services companies use different innovation strategies, in particular, outsourcing is quite widespread, given the high level of specialization and professionalism of companies that provide such services. The aim of this article was to evaluate the link between outsourcing of innovative activities and indicators of companies' efficiency. The methodology of the research includes the methods of correlation analysis and regression analysis to reveal the correlation between the use of outsourcing of innovative products and services and the turnover of the EU enterprises. The results show a high level of innovative activity of EU enterprises (50.3% innovatively active). Innovative business processes are the most widespread form of innovation activity (41% of enterprises implement business processes, and the indicator is higher than 41% in the most developed EU countries). The turnover of enterprises with new or substantially improved products was found to grow by 10.92% for the period 2016-2018. The correlation analysis shows weak direct links between the indicator of turnover growth and the number of enterprises that have independently implemented innovations, or have implemented innovations jointly with third-party companies, or using outsourcing services. The highest level of direct connection was found between the growth of turnover of enterprises that launched a new product for the market and the growth of the number of enterprises that implemented innovations with the involvement of organizations (correlation 0.273). Based on the regression analysis it was found that with a 1% change in the growth rate of the number of innovation-active enterprises, the growth rate of turnover from new or improved products increased by 5.67%. At the same time, with a 1% change in the growth rate of the number of enterprises that implement innovation through outsourcing, the growth rate of turnover from new or improved products will increase by 7.15%.

  • This study empirically examined how a firm size affects the determinants of innovative activities using the data of the Korean Innovation Survey (KIS) 2016. With data from 2,003 firms in the manufacturing sector, we performed logistic regression analysis and zero-inflated negative binomial regression analysis. R&D expenditure and patent applications were used as proxies for innovative activity. The independent variables included the firm's characteristics variables such as the firm's age, tech-level industry, RDemp (R&D employee ratio), venture, export, and industrial characteristics variables such as networking, appropriability, and spillovers. The empirical findings are that there are some differences in firms' innovative activity determinants among the firms' size groups. Next, strategic appropriability has negative impacts on small firms' R&D expenditure and medium-firms' patents. Networking is an important determinant of innovative activity for all firms, except for large firms. Furthermore, in deciding R&D activities, small and medium-sized firms were significantly influenced by industrial characteristics as compared to that of large firms. Our findings suggest some R&D promotion policies. Policies fostering firms' technological interaction would allow firms to take advantage of technological spillovers and thus raise the probability of investing in R&D.

  • In the manufacturing industry, fostering talented workers has become a core activity as well as an important resource leading to manufacturing enterprises' innovative activities, which has come to the fore as one of the biggest success factors for innovative activities indeed. In other countries, there are many researches actively conducted on talent-fostering programs related to manufacture innovation. In Korea, however, manufacturers or several different education agencies don't actively carry out manufacture innovation instructions and have failed to faster special competent workers since their instructions focus on theories most of the time. Therefore, this study was conducted to understand the present conditions of manufacture-innovative instructions in Korea by classifying them in a method of educational technology and to investigate various teaching methods through oversea cases and cases from non-manufacture fields so that it might make a proposal for a better manufacture-innovative instruction method.

  • Although patents have mainly been considered as the results of the invention process, of late their value as strategic assets have increasingly been emphasized. Consequently, the competition for patents among firms has intensified, and the number of patent disputes have been steadily increasing. Patent disputes, which cause enormous expense and resource utilization, increase uncertainty and have been considered as a threat or problem for the firms involved. Patent disputes are expected to have a significant impact on the decision making about subsequent innovation activities. This study attempts to analyze the effect of patent disputes on the subsequent innovative activities of the firms that are sued. After experiencing litigation as defendants, we examine their subsequent patenting strategies. According to the results of the study, firms who are experiencing patent litigation are more likely to achieve high-quality patents and cite recent technology when they apply for patents. Meanwhile, patent litigation experience has been shown to negatively affect the amount of subsequent patents applied. This study increases understanding by examining whether patent disputes, which have been mainly recognized negatively as obstacles, can be an opportunity that comes during a crisis.
