With the increasing importance of technology, the efficiency of R&D investment is becoming a critical factor to an organisation’s success. As a result, many studies have carried out to create useful information to support various decision-makings faced during R&D planning but few efforts were made to discuss technology transferability in creating the information. Technology transferability can be an important factor to increase the efficiency of R&D investment especially in a multi-technology industry, where a compound of several industries produces a variety of components and systems. Therefore, this study purposes to develop a systematic method to analyse the transferability of technology, aiming to facilitate R&D spill-over. For the purpose of analysis, patent data from USPTO (United States Patent and Trademark Office) was adopted and patent citation analysis applied, which shows the relationship between technologies and industries as quantitative measures. The research result then was applied to Korean aerospace industry and its utility verified. The suggested method is expected to be used in understanding technology characteristics and making the most use of R&D outputs by promoting technology transfer in multi-technology industries.  相似文献

The objective of this study was to determine the presence of corticosteroids in illegal herbal medicines using ultra‐high‐performance liquid chromatography–tandem mass spectrometry. We collected 212 herbal medicine samples that were advertised as being effective for treatment of joint pain and bone aches. Samples were from the Korean commercial market during a span of four years (2010–2013), and the method was validated. The limits of quantification ranged from 0.47 to 15.0 ng/mL, and recoveries ranged from 80.6% to 119.5%. The intra‐ and interday precision ranged from 0.18% to 8.82% and from 0.09% to 8.96%, respectively. Among the samples, three samples (1.4%) were identified as adulterants. Dexamethasone was the only compound detected in the adulterated products. As the corticosteroid–adulteration of herbal medicines may become a major problem and lead to side effects, the continued development of screening procedures for herbal medicines is critical.  相似文献

Specialized courts raise questions about the decisions that bring some defendants into such courts and keep others out. Because of risks perceived in diverting mentally ill defendants, decisions to select defendants for mental health courts are especially interesting. I estimate a model of the decision to divert defendants into court‐monitored mental health treatment. I find that gender and age combine to disadvantage young male defendants and older female defendants. The findings point to the importance of structuring selection processes in the design of specialized courts. They shed light on the consequences of including treatment personnel in justice system decisions.  相似文献

The article draws on a source of unusual completeness and accuracy—the genealogical archives of the Qing imperial lineage—to provide an initial quantitative study of son adoption among the Qing nobility during the last imperial dynasty (1644–1911). Adoption was used rather frequently not only for genealogical purposes to continue the ancestral line, but also for economic security. Adoption was also an integral component of the Chinese historical demographic system and therefore varied in frequency according to the level of fertility and mortality. After a discussion of the sources for lineage population history, the article calculates the levels of son adoption over time and highlight the demographic and economic circumstances leading to adoption. It then analyzes the social relationships between biological and adoptive parents as a function of noble status and generational distance, and comments on the role of adoption as a means of social mobility within the lineage population.  相似文献
