  • Now days, firm's technology capability is recognized as important factor to forecast and to evaluate firm's business performance. There are many efforts to develop useful indicators by applying patent information that includes concrete description about technology. Many previous studies analyzed relationship between patent indicators and firm's performance. But they didn't consider time gap between a point of firm's invention activity and a point of firm's performance improvement. They didn't considered a character of industrial fields either. To overcome these limitations, we selected IT industry for target analysis industry. Time-series patent data and financial data from 41 American IT firms between 2000 and 2011 were used to analyze. In this study, We empirically analyzed subsequent effect of patent indicators on firm's business performance by using correlation analysis and regression analysis.

  • The objective of this research is to search the solution for the difficulties of science and invention gifted middle school students with social and emotional problems that they are faced. The result of this research has shown that the gifted students were feeling difficulties of low self-esteem in their peer relationships, communication and cooperation skills. They were feeling less confident in their stress processing capacity and their multi-processing capacity. Some were also troubled with the intense expectations from their environment and theirselves which led them to feel confusion in their identities and their future. Therefore, instead of education focused on academic achievement and cognitive activity, present education for the gifted must focus on helping to solve the student's social and emotional problems and to strengthen social and emotional skills they need. To achieve this, the education for the gifted students should include a social-emotional learning program, and it should also run a continued and personalized consultation program for gifted students.

  • The purpose of this study is to suggest the desirable direction toward the creative hand-on activities suitable for the characters of the technical high school students by examining the teachers' recognition of sub-factors of creative activities in technical high school and analysing whether the factors are properly utilized. Respondents of this study were 393 teachers at the Technical high school in South Korea. The questionnaire survey on the recognition of creative hand-on activities consisted of questions, which are importance and reflection, from 32 sections in 5 fields. The summary of the results through this study is as following. First, In the results of importance analysis of teachers in technical high school, in club activity field, 'the invention' of 'academic activity', 'film-art' in 'culture-art activity', 'challenge activity' in 'sports activity', 'school specialized major' in 'work practice activity', 'scout federation', 'Red Cross youth activity' in 'youth group activity' were seemed to be higher. Second, In the results of reflection analysis, it was found that the 'academy, culture-art', 'sports activity' fields were similarly reflected in importance thought by teachers in technical high school. However, for 'the work practice activity' and 'youth group activity', except 'the school specialized major', all fields are not properly reflected, independent of importance. For 'the work practice activity', analyses of importance and reflection seemed to be alike but for 'the youth group activity', there was a significant difference between them.

  • 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.

  • The paper proposes a knowledge innovation performance model by the dynamic data envelopment analysis with slacks-based measure approach for evaluating the effectiveness of 30 regional knowledge innovation activities in China from 2010 to 2016. In recent years, China has paid more attention to knowledge innovation activities, as central and local governments have pushed on with their innovation projects by lots of investment whatever the difficulties may be. Decision-maker is usually interested in judge its knowledge innovation performance relative to target benchmark by exploring whether one provincial administration region performs better among others and/or if the growth of economy will be benefited greatly by the knowledge innovation activities. To acquire the managerial insight about this issue from a comprehensively designed performance evaluation model, knowledge innovation activity is conceptualized as an intertemporal production process. Invention patent and regional gross product are imposed on desirable outputs, highlighting the need for knowledge economy. The empirical result shows that knowledge innovation has a positive effect on economic development. At the same time, decision-maker should be interest in the economic effect of patents' type and quality. The government should then encourage new technical applications with greater commercial value from a market-oriented perspective, in order to benefit the most from the innovation process in the short-run.
