The purpose of this study is to examine the unique characteristics of the Korean academic system with regard to brain circulation, with a specific emphasis on the influence of overseas-trained academics on research activities within the Korean academic system. We have analyzed the statistical data on individual characteristics and performances of 48,499 Korean academics in science and engineering. We have examined the results at both the system and individual levels within the broader context of the macro characteristics of the Korean academic system. Our analysis reveals that the total number of domestically-trained academics exceeds the number of overseas-trained academics. However, in terms of research funding, overseas-trained academics tend to receive more funding than domestically-trained academics. Furthermore, after controlling other factors such as funding, personal attributes, and environmental factors, our analysis demonstrates that overseas training has a significant and favorable impact on the publication of internationally renowned journals. As such, the presence of overseas returnees has been essential for the effective functioning of the Korean academic system in the global research network and for conducting high-quality academic research. Therefore, the advantages of dependence on scientific core countries such as the US for overseas training have persisted. Nevertheless, upon scrutinizing the group of recently appointed 5,806 academics exclusively, we have discovered that junior academics who received their education domestically exhibit sufficient academic proficiency compared to their colleagues educated overseas. This observation highlights the potential for the Korean academic system to evolve into a self-sustaining system.

신제품 개발 과정에서 성공적인 혁신을 창출하기 위해서는 외부 파트너와의 원활한 협력관계 뿐만 아니라 부서 간 장벽을 허무는 노력도 요구된다. 이 연구는 대중소 기업간 신제품 개발 협력과정에서 혁신창출의 성공요인들이 어떻게 작용하는지 분석하였다. 대형 소매업체와 두 개의 중소협력사들의 협력관계 구축을 통한 신제품 개발 과정에 대한 사례 분석을 실시한 결과 적어도 단기적으로는 중소협력사들이 매우 큰 성장율을 달성하였음을 발견하였다. 기업 간 협력을 통한 혁신의 성공요소들 가운데, 대기업의 관계 특정적 투자가 중소협력업체의 참여 동기에 결정적 영향을 미쳤음을 발견하였다. 또한 두 개의 중소협력사들이 직접 상호작용하는 이른바 '폐쇄적' 네트워크를 구축하여 신제품 개발에 필요한 지식을 창출함으로써 짧은 시간에 고품질의 상품개발에 성공할 수 있었다. 식품산업에서 소매업체와 공급업체간 협력에 의한 신제품 개발에 관한 기존 연구들이 커뮤니케이션 문제를 야기하는 상호 입장 차이를 성패결정의 핵심요소 중 하나로 보았으나 본 연구에서는 대기업과 중소기업간 협력의 경우 대형 소매업체의 주도적 역할이 오히려 핵심적 기능을 한 것으로 나타났다.

1960년대 설립 이후 우리나라 과학기술계 정부출연연구기관은 다양한 연구개발성과 창출을 통해 국가 경제 및 산업 발전에 공헌해왔다. 그러나 2000년대 이후 산업계와 학계의 연구역량 향상에 따라 투자 대비 성과 창출이 부족하다는 비판과 압력에 지속적으로 직면해왔다. 이에 따라 본 연구에서는 정부출연연구기관의 연구개발 성과의 경제적 편익 추정을 위한 분석 틀로 기술이전, 중소기업 지원과 같은 연구개발 성과 요인별 경제적 편익을 개별적으로 산출하여 더하는 '상향식 접근'과 (2) 출연(연)의 성과가 이전 확산되는 산업의 경제적 성장에 대한 기관의 기여도를 산출하는 '하향식 접근'을 제시하였다. 또한 이러한 분석 틀을 활용하여 K연구원이 1996년~2014년 달성한 연구개발 성과의 경제적 편익을 각각 12.3조원과 29.5조원으로 산출하고, 상호보완적인 관점에서 두 접근방법의 활용 가능성을 탐색적으로 제시하였다. 본 연구는 과학기술계 정부출연연구기관의 연구개발 성과에 따른 경제적 편익을 체계적이면서 중장기적 관점에서 추정할 수 있는 분석적 기반을 마련하는데 그 의의를 두고 있다. 아울러 본 연구는 실무적 관점에서 과학기술에 대한 국민들의 이해를 증진시키고, 연구개발 성과의 수혜자가 바로 국민임을 인지하게 함으로써 궁극적으로 동 기관의 정당성에 대한 국민들의 지지와 성원을 제고하는데 기여할 것으로 기대된다.

A novel method for ab initio prediction of protein tertiary structures, PROFESY (PROFile Enumerating SYstem), is introduced. This method utilizes secondary structure prediction information and fragment assembly. The secondary structure prediction of proteins is performed with the PREDICT method which uses PSI-BLAST to generate profiles and a distance measure in the pattern space. In order to predict the tertiary structure of a protein sequence, we assemble fragments in the fragment library constructed as a byproduct of PREDICT. The tertiary structure is obtained by minimizing the potential energy using the conformational space annealing method which enables one to sample diverse low lying minima of the energy function. We apply PROFESY for prediction of some proteins with known structures, which shows good performances. We also participated in CASP5 and applied PROFESY to new fold targets for blind predictions. The results were quite promising, despite the fact that PROFESY was in its early stage of development. In particular, the PROFESY result is the best for the hardest target T0161.

The market of programmable implantable pumps has bound to a monopolistic situation, inducing high device costs, thus making them inaccessible to most patients. Micro-mechanical and medical innovations allow improved performances by reducing the dimensions. This affects the consumption and weight, and, by reducing the number of parts, the cost is also affected. This paper presents the procedure followed to design an innovative implantable drug delivery system. This drug delivery system consists of a low flow pump which shall be implanted in the human body to relieve pain. In comparison to classical known solutions, this pump presents many advantages of high interest in both medical and mechanical terms. The first section of the article describes the specifications which would characterize a perfect delivery system from every points of view. This concerns shape, medication, flow, autonomy, biocompatibility, security and sterilization ability. Afterwards, an overview of existing systems is proposed in a decisional tree. Positive displacement motorized pumps are classified into three main groups: the continuous movement group, the fractioned translation group and the alternative movement group. These systems are described and the different problems which are specific to these mechanisms are presented. Since none of them fully satisfy the specifications, an innovation is justified.. The decisional tree is therefore extended by adding new principles: fractioned refilling and fractioned injection within the fractioned translation movement group, spider guiding system within the alternative translation movement group, rotational bearing guided device and notch hinge guided device in the alternative rotation movement group.

This paper considers a scheduling problem in a flexible job shop with a reconfigurable manufacturing cell. The flexible job shop has both operation and routing flexibilities, which can be represented in the form of a multiple process plan, i.e. each part can be processed through alternative operations, each of which can be processed on alternative machines. The scheduling problem has three decision variables: (a) selecting operation/machine pairs for each part; (b) sequencing of parts to be fed into the reconfigurable manufacturing cell; and (c) sequencing of the parts assigned to each machine. Due to the reconfigurable manufacturing cell's ability of adjusting the capacity, functionality and flexibility to the desired levels, the priority scheduling approach is proposed in which the three decisions are made at the same time by combining operation/machine selection rules, input sequencing rules and part sequencing rules. To show the performances of various rule combinations, simulation experiments were done on various instances generated randomly using the experiences of the manufacturing experts, and the results are reported for the objectives of minimizing makespan, mean flow time and mean tardiness, respectively.

Dual-energy X-ray imaging (DEI) techniques can provide X-ray images that a certain material is suppressed or emphasized by combining two X-ray images obtained from two different x-ray spectrum. In this paper, a single-shot DEI, which uses stacked two detectors (i.e., multilayer detector), is proposed to reduce the patient dose and increase throughput in angiography. The polymethyl methacrylate (PMMA) and aluminum (Al) were selected as two basis materials for material decomposition, and material-specific images are reconstructed as a vector combination of these two materials. We investigate the contrast and noise performance of material-decomposed images using iodine phantoms with various concentrations and diameters. The single-shot DEI shows comparable performances to the conventional dual-shot DEI. In particular, the single-shot DEI shows edge enhancement in material-decomposed images due to the different spatial-resolution characteristics of upper and lower detectors. This study could be useful for designing the multilayer detector including scintillators and energy-separation filter for angiography purposes.

본 연구의 목적은 혁신활동이 기업의 경영성과에 미치는 영향을 밝히는 데 있다. 이러한 연구는 1960년대 이후 활발하게 진행되어 왔는데, 이론과 달리, 실증분석에서는 혼재된 결과가 나타났다. 실증분석 결과가 이론과 다론 이유는 많이 있지만, 사용되는 통계와 분석 방법의 차이에 기인하는 바가 크다. 본 연구는 이러한 문제의식의 연장선상에서 통계문제를 최소화하기 위해 노력하였다. 특히, 이용 가능한 통계를 최대한 활용하기 위해, 특허청에서 제공되는 특허 출원건수의 전수통계(1990~2008)를, 연구개발은 한국신용평가기관에서 제공되는 연구개발비용 통계(1990~2008)를 사용하였다. 본 연구의 가장 큰 의의는 바로 방대한 통계작업이라 할 수 있다. 적절한 지표 산정을 위해, 주성분 분석을 활용하여 혁신성 지수를 산출하였고, 기업 패널분석과 고성장 기업의 분석에 적절한 분위수 추정을 함께 사용하여 다양한 유형의 기업들에게 미치는 효과를 측정하였다. 분석결과를 보면, 패널 분석에서는 혁신활동이 기업의 경영성과에 미치는 영향이 유의적이지 않지만, 분위수 추정에서는 이와 다른 결론을 도출하였다. 특히, 하위 10%에 해당하는 저성장기업에게는 혁신이 유의하지 않지만, 상위 10%의 고성장 기업에게는 혁신활동이 매우 중요한 영향을 끼치는 것으로 나타난다. 혁신활동이 대기업보다 중소기업에 보다 큰 영향을 미치는 것으로 나타난 점 역시 커다란 시사점이라 할 수 있다.

The objective of this paper is to think about what structural reforms of the Korean government S&T development management system might be. Korean society is currently experiencing a drastic socio-economic transformation. The results of this transformation should be reflected on the determining process of the directions and breadths of structural reforms of government S&T development management system. Because the government system design will be based on the premises of socio-economic conditions under which administrative activities perform and also this socio-economic changes can influence on changes of the premises of government management system design. Moreover, S&T development management system is a subsystem of government system so that the directions of structural reform of those subsystems should be considered in the broad framework changes in the development management system of the government. For the last forty years, the Korean government S&T development management system has been based on the premises including transformation from an agrarian society to an industrial society, authoritarianism and centrally controlled institutions, and exteremely small portions of private investments for science and thechonology R & D of the total. Recently, however, the premises of Korean government S&T development management system have rapidly changed. the characteristics of these changes are including tranformation from an industrial society to a knowledge and information intensive society, globalization, localization, and relatively large portion of private investments for science and technology R & C of the total. The basis of government reforms in Korea was the realization of the performances and values through the enhancement of national competitive capacity, attainment of lean government, decentralization and autonomy. However, the Korean government has attached a symbolic value of strategic organizations representing strong policy intentions of government for the science and technology based development. Most problems associated with the Korean government S&T development management system have grown worse during 1990s. Many people perceive that considerable part of this problem was generated because the government could not properly adapt itself to new administrative environment and the paradigm shift in its role. First of all, the Korean government S&T development management system as a whole failed to develop an integrated vision under which processes in formulating science and thechology development goals and developing consistent government plans concerning science and technology development are guided. Second, most of the local governments have little organizational capacity and manpowers to handle localized activities to promote science and technology in their regions. Third, the measure to coordinate and set priorities to invest resources for the development of science and technology was not effective. Fourth, the Most has been losing its reputation as the symbol of ideological commitment of the top policy maker to promote science and technology. Various ideas to reform government S&T development management system have been suggested recently. Most frequently cited ideas are as follow : (ⅰ)strengthen the functions of MoST by supplementing the strong incentive and regulatory measures; (ⅱ)create a new Ministry of Education, Science & Technology and Research by merging the Ministry of Education and the MoST; (ⅲ)create a new Ministry of Science & Technology and Industry ; and(ⅳ)create a National Science and Technology Policy Council under the chairmanship of the President. Four alternatives suggested have been widely discussed among the interested parties and they each have merits as well as weaknesses. The first alternative could be seen as an alternative which cannot resolve current conflicts among various ministries concerning priority setting and resource allocation. However, this alternatives can be seen as a way of showing the top policymaker's strong intention to emphasize science and technology based development. Second alternative is giving a strategic to emphasize on the training and supplying qualified manpower to meet knowledge and information intensive future society. This alternative is considered to be consistent with the new administrative paradigm emphasizing lean government and decentralization. However, opponents are worrying about the linkages and cooperative research between university and industry could be weakening. The third alternative has been adopted mostly in nations which have strong basic science research but weak industrial innovation traditions. Main weakness of this alternative for Korea is that Korean science and technology development system has no strong basic science and technology research traditions. The fourth alternative is consistent with new administrative paradigms and government reform bases. However, opponents to this alternative are worried that the intensive development of science and technology because of Korea's low potential research capabilities in science and technology development. Considerning the present Korean socio-economic situation which demands highly qualified human resources and development strategies which emphasizes the accumulations of knowledge-based stocks, I would like to suggest the route of creating a new Ministry of Education, Science & Technology and Research by intergrating education administration functions and science & technology development function into one ministry.
