This study investigates the effect of high-skilled inventor emigration rate on growth rate of the country of origin (COO). Inventor emigrants represent the human capital that can generate highly innovative work. The social network they form spurs knowledge diffusion and technology transfer back to their COOs, which in turn affects innovation and growth in their home countries. We run dynamic panel estimation for 154 countries during 1990-2011, and empirically show that a positive and statistically significant effect exists for the interaction of inventor emigration and trade. The result indicates that the direct negative impact of the brain drain can be mitigated by the positive feedback effect generated by the high-skilled inventor emigrants abroad. When coupled with an active trade policy that reinforces growth, countries can partially recoup the direct effect of the human capital loss. We stress the importance of international trade for successful technology transfer to occur, and offer insights for policies that can utilize the benefits of the rich social network of their high-skilled emigrants.

본 논문은 내국인 특허출원 자료에서 복수 발명자들의 주소지들을 파악하고 가산자료의 특성을 통제할 수 있는 영과잉 음이항 회귀모형을 사용하여 230개 시군구 간 발명자 네트워크의 공간구조와 그것의 결정요인을 분석한다. 발명자 네트워크의 공간적 연계에 영향을 미치는 몇 가지 요인들이 확인된다. 이출지역이 민간 R&D, 고등교육수준, 인구규모, 특허 생산성 등과 같은 R&D 관련 지역 특수적 자산들을 많이 보유하면 동태적인 수요효과를 통해 공간적 연계는 다른 지역으로 확대된다. 그리고 물리적 거리뿐만 아니라 기술적 거리에서도 거리조락현상이 나타난다. 이입지역이 R&D 관련 지역 특수적 자산을 많이 보유하면 유사한 논리로 공간적 연계에서 정(+)의 효과가 발생한다.

Technological convergence is yielding new values and affecting various fields not by single technology but by convergence between technologies. This study aims to analyze the IT -BT-NT convergence and differences between technologies in respect of collaboration within (inventor) and between (assignee) organizations. Among the main technologies leading the technological convergence, IT is the most active of converging with other fields. BT is knowledge-intensive and strong cooperative networks are important in this area. NT is applied in various industrial fields upon the basic technology. Using the data on applied and granted patents by Korean applicants in the U.S., this study conducted quantitative analysis and ANOVA to gain the following results. First, the degree of convergence in between IT-BT-NT is continuously increasing since 2002. Second, BT is where the collaboration within and between organizations is the most active among IT-BT-NT. Third, there were certain differences in the degree of convergence according to the years and the fields of technologies in all the IT-BT-NT. Organizations cooperate with other institutions to sustain their competitiveness with limited internal resources. Companies in these fields are recommended to perform diverse strategies to pursue further collaboration with the outside.

Purpose: This study addressed the relationship among nutritional risk, stress, and health related quality of life for older women with a foreign daughter-in-law. Methods: A descriptive research design was used for this study. The subjects of this study were 112 older women with a foreign daughter-in-law all of whom were over 65 years and living in D city. Personal interview was used for data collection. Nutritional risk, stress, and health related quality of life were measured using Nutrition Screening Initiative (NSI), Family Inventor of Life Events and Changes (FILE), and Medical Outcome Study (MOS) Short-form 36-Item Health Survey (SF-36), respectively. Results: Older women with a foreign daughter-in-law showed negative correlation between quality of life related health and nutritional risk, stress and age, and positive correlation between Activities of Daily Living (ADL); 46% of variance in health related quality of life of older women with a foreign daughter-in-law was explained by nutritional risk, ADL, stress and occupation. Conclusion: Based on the results of this study, we suggested that specialized programs should be established to help in development of social relationship networks for older women who have a foreign daughter-in-law.
