Technology-oriented national R&D programs produce intellectual property as their final result. Patents, as typical industrial intellectual property, are therefore considered an important factor when evaluating the outcome of R&D programs. Among the main components of patent evaluation, in particular, the patent right quality is a key component constituting patent value, together with marketability and usability. Current approaches for patent right quality evaluation rely mostly on intrinsic knowledge of patent attorneys, and the recent rapid increase of national R&D patents is making expert-based evaluation costly and time-consuming. Therefore, this study defines a hierarchy of patent right quality and then proposes how to quantify the evaluation process of patent right quality by combining text mining and regression analysis. This study will contribute to understanding of the systemic view of the patent right quality evaluation, as well as be an efficient aid for evaluating patents in R&D program assessment processes.

In recent years, the intellectual property rights (IPR) are increasingly becoming trade goods and the subject of international trade negotiations. During the past decades, intellectual properties earned critical importance for economic development in both developed and developing countries. Developed countries, headed by the United States, that recognize the economic value of the IPR in the world market are aggressively seeking for universal protection of IPR throughout the world. Intellectual properties have unique qualities that distinguish them from other tangible goods. Most importantly, they are public goods created on the basis of knowledge and information accumulated throughout human history and shared by different cultures. However, there is a growing tendency that the quality of public goods are being etched away as the property concept in IPR expands. In this paper, I discuss how copyright and patent laws incorporated the concept of property right as natural right to one's intellectual creations in early formation of the laws in Europe. I argue that copyright law and patent law are the historical products resulting from political, economic, and ideological factors interacting in a certain society. A history of copyright and patent points to that the intellectual property rights as natural lights of authors and inventors as argued by developed countries in international disputes, are not universal, but unique historical products. Copyright and patent laws have been shaped and developed as regulatory measures by governments to promote and control industries by providing authors and inventors with monopoly incentives. Since property right was used as a regulatory device it was restricted. This is to enhance the distribution of knowledge and information rather than to ensure the property right as an absolute right.

This paper explores the determinants of the economic value of patents using a survival time analysis. The analysis is based on renewal information of about 250,000 patents filed from 1984 to 2005 in the Korea Intellectual Property Office. A patent right is valid only when its owner pays yearly maintenance fees. Failure to pay causes patent rights to be lapsed. We use the fact that more valued patents live longer and the lengths of their renewals can be closely related to their value. The value can be affected not only by its own technological aspects such as quality and breadth, but also by characteristics of its owners such as innovativeness and age. This paper presents patent-specific and firm-specific characteristics which influence patent value. The result of analysis implies that patent value depends on both the technological contents of the patent and general capabilities of a firm.

Twenty eight patients with conpnital heart disuse underwent lung biopsy to assets pulmonary obstructive vascular disease at cardiac surpry. Thirteen patients had patent ductus arteriosus, 10, ventricular septal defects and S, atrial septal defects. The aaes were between 2 and 30 years. In patients with patent ductus arteriosus lung biopsy was performed from the IIngular Hlment. The anterior seament of the right upper lobe was blopsled in cases with ventricular septal defect and atrial septal defect. Grading of pulmonary obstructive vascular disease could not be assessed In 9 cases. In 2 cases poor quality of the slides made us impossible to evaluate and In 7 cases there were no suitable small muscular arteries to evaluate in the slides of lung tissue especially taken from the IIngular seament. Nineteen cases were evaluated pulmonary obstructive vascular disease. Among them 17 cases had Heath-Edwards changes of grade 1 and 2 patients had that of grade 3. The thickness of media was measured. It was expressed as percentage of medial thickness to outer diameter of artery. The medial thickness was correlated proportionally with elevation of pulmonary arterial pressure and pulmonary vascular resistance to systemic vascular resistance ratio. There were no complications related to the procedure of lung biopsy.

Objective : The heart diseases are known as a major cause of sudden death, as well as a cause of poor life-quality of school-age children. But there have been few mass screening of heart diseases in these children in Korea. This study was done to estimate the prevalence of heart diseases of these population. Methods : We screened all elementary students(grade 1) in 12 cities and 16 counties(Gun) in Kyonggi province from 1992 to 1955. The first screening was done by auscultation of doctors and simultaneously by checking using 'auto-interpreter of EKG-cardiac sound' (Fukuda Densi ECP 50A). We conducted luther examinations to whom classified as being abnormal condition in first screening, by using EKG, chest x-ray, doppler echocardiograpy(if needed). Results : The total number of examined students was 161,308(92% of the population), the male were 83,238 and female were 78,070. The congenital heart diseases(CHD) patients were 290(18 per 10,000) - male 155(18.6 per 10,000) and female 135(17.3 per 10,000). The most frequent disease was ventricula septal defect(VSD, 45.5%), Atrial septal defect(ASD, 14.8%), Tetralogy of Follot(TOF, 11.7%), and Patent Dutus Arteriosis(PDA, 7.6%) in order. In female, the order was VSD(48.1%), ASD(13.3%), TOF(11.1%), and PDA(10.4%). The total number of EKG abnormality were 433(62.7 per 10,000) among 69,056 screened children in 1995. The complete right bundle branch block(CRBBB) and paroxymal ventricular contraction(PVC) were frequent(26.6%, 26.3% in each), and incomplete right bunddle branch block(IRBBB, 14.6%), paroxymal atrial contraction(PAC, 6.7%), abnormal Q(5.8%), Wolf-Pakinson-White syndrom (5.5%) in order. In female, the most frequent abnormality was PVC(29.8%), and CRBBB(19.9%) in order. Conclusion : We could present the stable prevalence of the rare heart disease. The prevalence of congenital heart diseases was 18.0 per 10,000 and of EKG abnormality was 62.7 per 10,000 among school children.

본 연구는 부품공급 중소기업의 전략적 적합성과 대기업과의 협력관계가 부품공급 중소기업의 성과에 미치는 영향에 대해 조사하고자 한다. 이를 위해, 삼성전자의 1차 협력사 90개 기업을 대상으로 대기업과 전략적 적합성 및 대기업과의 협력관계가 중소기업의 기업성과에 미치는 영향을 분석하였다. 실증분석 결과, 전략적 적합성은 중소기업의 경영성과와 혁신성과 모두에 긍정적인 영향을 미치는 것으로 나타났다. 따라서 중소기업이 경쟁력을 제고시키기 위해서는 환경에 적합한 전략을 추구해야 한다는 기존 이론적 주장을 뒷받침한다. 둘째, 대기업과의 협력에 있어 기술 및 인력 협력과 협력의 질이 부품공급 중소기업의 경영성과와 혁신 성과 모두에 긍정적인 영향을 미치는 것으로 나타났다. 즉, 대기업과의 기술 및 인력 협력을 통해 부품공급 중소기업의 생산성 및 효율성을 제고시켜 경영성과를 높일 수 있을 뿐만 아니라, 혁신성과 역시 달성할 수 있음을 보여준다. 셋째, 대기업과의 기술 및 인력 협력과 협력의 질이 전략적 적합성과 혁신성과 간의 관계에서 상호작용 효과가 있는 것으로 나타났다. 이는 부품공급 중소기업이 환경의 불확실성이 높은 경우 차별화 전략을 추구하고 원청 대기업과 장기 지향적이고 상생적인 형태 협력을 수행함으로써, 더 많은 특허출원과 같은 혁신성과를 달성할 수 있음을 보여준다. 반면, 환경의 불확실성이 낮은 경우에는 원가우위 전략을 추구하고 원청 대기업과 기술 및 인력 협력을 수행함으로써, 더욱 큰 혁신성과를 달성할 수 있음을 시사한다. 본 연구는 이러한 연구결과를 토대로 부품공급 중소기업이 경쟁력을 창출하기 위해서는 환경에 적합한 경쟁전략의 선택과 실천뿐만 아니라, 원청 대기업과의 기술 및 인력 협력 강도와 협력의 질이 중요한 영향을 미침을 주장한다. 이러한 주장은 중소기업의 경쟁력 제고를 위해 경쟁과 협력이 모두 중요함을 시사한다.

관상동맥우회술 후 이식편의 조기 열림을 판정하기 위한 CT 조영술은 비침습적이고 간단하며 안전한 방법으로 알려져 있다. 저자들은 관상동백 우회술 환자들에서 수술 후 퇴원 전에 CT 조영술을 시행하여 이식편의 조기 열림의 판정에 대한 여부와 영상에 미치는 인자들을 조사하였다. 대상 및 방법: 관상동맥 우회술을 받은 50예에서 수술 후 퇴원 전에 4개의 검출기를 가진 CT기로 조영술을 시행하고 내흉동맥 이식편(50편), 요골동맥편(18편), 대퇴정맥편(56편)의 조영상해로 이식편의 열림을 조사하고 이식편의 조영상태와 문합혈관의 직경, 부행혈류 및 협착정도와의 관계를 분석하였다. 결과: 좌관상동맥계에 문합되는 정맥편(24편, 32문합부)은 모두 잘 조영되었으나, 우관상동백계에 문합된 정맥편(30편, 35문합부) 중 3편 (4.7%)은 CT 조영술에서 조영되지 않았고 대퇴동맥을 통한 침습적인 관상동맥 조영술에서도 폐쇄된 소견을 보였다. 내흉동맥편 중 39편(78%)은 CT 조영술에서 잘 조영되었고 8편(16%)은 일부 좁아지거나 끊기는 불완전한 조영을 보였으며 3편(6%)은 조영되지 않았으나 동맥을 통한 침습적인 관상동맥 조영술에서는 모두 정상적인 열림 소견을 보였다. 결론: 관상동맥조영술 후 CT 조영술에서 조영되지 않는 정맥편은 페쇄를 의미하나, CT조영술에서 조영되지 않는 동맥편은 폐쇄가 아닌 관상동맥과 이식편 사이의 상경혈류 때문에 일어날 수 있으므로 조영이 안 되는 동맥편의 열림을 확인하기 위해서는 침습적인 관상동맥조영술이 필요할 것으로 생각된다.
