The Korean government implemented a policy in 2012 to bring structural changes to the pharmaceutical industry whose dependence on generic drugs was high and innovation capacity to develop new drugs was low. The policy was comprised of two parts, price reduction of generic drugs and supports of selected innovative pharmaceutical firms with tax credits, higher drug prices, and various managerial benefits. The objective of this study was to assess the impacts of the policy by examining firm level responses in internal research and development (R&D) investment and effort to acquire external R&D resources through strategic alliances and merger and acquisitions (M&As). The study also examined innovation outputs (numbers of patent registration and clinical trials) which are results of R&D inputs and the final financial outcome (revenue). The study collected data for 46 publicly listed firms on the KOSPI and KOSDAQ markets during 2009-2016, 20 selected innovative firms and 26 non-selection firms, and compared the study variables of the two groups to estimate the impacts with differences-in-differences (DD) and panel regression DD with control variables. Results indicated that selected innovative firms were superior to their couterpart firms in R&D inputs, innovation outputs, and financial outcome in the first place, and the government supports strengthened their superiority in internal R&D investments, alliances and M&As, and patent registration. However, the policy did not have any influence on the number of clinical trials and revenue, and the reduction of drug prices did not have statistically significant impacts on the study variables either. The study contributed in providing policy makers and firm managers with directions for the advancement of the Korean pharmaceutical industry despite the limitation of short data period and the generalizability problem.
실시간 화상처리 기법을 이용한 다물체 위치 추정에 관한 연구

본 연구는 실시간 고속 다물체 화상처리 기법을 개발하고자 한다. 최근 들어 비젼 시스템의 응용은 검사 및 로봇위치 제어등 여러 분야에서 급속히 증가되고 있다. 비젼 시스템을 이러한 응용분야에 적용하기 위해서 3차원 공간상 물체 위치 값을 CCD카메라로부터 얻어진 이미지 정보를 변환하는 것이 필요하다. 검사 및 로봇위치 제어 등에 비젼 시스템을 적용하기 위해서는 이미지 평면에서 물체의 중심위치를 아는 것이 필요하다 특히 3차원 강체들의 경우에는 형상을 나타내기 위해서는 여러 개의 큐들이 필요하므로, 여러 개의 큐들의 위치 값들이 하나의 이미지 평면에서 동시에 결정되어야 한다. 이러한 문제를 해결하기위해 여러 개 큐들을 동시에 처리하는 다물체 화상 처리 기법을 본 논문에서 제시하고 개발된 알고리즘의 타당성을 실험을 통하여 보여준다. This study is to develop the high speed multi-object image processing algorithm in real time. Recently, the application of vision system is rapidly increasing in inspection and robot's position control. It is necessary to transform the physical coordinate of object into the image information acquired by CCD camera, which is called image processing, in order to apply the vision system. Thus, it is necessary to know the position of object in the image plane to apply the vision system in the inspection and robot's position control. Particularly, in case of rigid body using multi-cue to identify its shape, each position of multi-cue must be calculated in an image plane at the same time. To solve these problems, the image processing algorithm on the position of multi-cue is developed. Finally, the experiments are performed to show the practicality of this algorithm.
