본 논문에서는 사용자의 손바닥 위에 증강되는 가상 객체와의 자연스러운 상호 작용을 제공하는 혁신적인 손 기반 인터페이스를 제안한다. 본 인터페이스에서는 한 손바닥 위에 다른 쪽 손의 손가락으로 미리 정의된 패턴을 그린 후 그 패턴을 인식함으로써 가상 객체들이 용이하게 선택되도록 한다. 이렇게 선택된 가상 객체들은 계산된 손바닥 포즈를 이용해서 손바닥 위에 증강된다. 손가락으로 그려진 패턴을 효과적으로 검출하기 위해 손가락을 감쌀 수 있는 마커를 사용하여 손가락의 궤적을 추적한다. 넓은 범위의 손바닥 포즈를 계산하고 손가락의 움직임을 인식함으로써 사용자는 다양한 시각에서 손바닥 위의 증강된 가상 객체와 자연스럽게 상호 작용할 수 있다.

The MBR (Memory Based Reasoning) is a supervised learning method that utilizes the distances among the input and trained patterns in its classification, and is also called a distance based learning algorithm. The MBR is based on the k-NN classifier, in which teaming is performed by simply storing training patterns in the memory without any further processing. This paper proposes a new learning algorithm which is more efficient than the traditional k-NN classifier and has incremental learning capability, Furthermore, our proposed algorithm is insensitive to noisy patterns, and guarantees more efficient memory usage.

The artificial intelligence (AI) is a technology that will lead the future connective and intelligent era by combining with almost all industries in manufacturing and service industry. Although Korea is one of the world's leading artificial intelligence group with the United States, Japan, and Germany, but its competitiveness in terms of artificial intelligence patent is relatively low compared to others. Therefore, it is necessary to carry out quantitative analysis of artificial intelligence patents in various aspects in order to examine national competitiveness, major industries and future development directions in artificial intelligence technology. In this study, we use the IPC technology classification code to estimate the overall life cycle and the speed of development of the artificial intelligence technology. We collected patents related to artificial intelligence from 2008 to 2018, and analyze patent trends through one-dimensional statistical analysis, two-dimensional statistical analysis and network analysis. We expect that the technological trends of the artificial intelligence industry discovered from this study will be exploited to the strategies of the artificial intelligence technology and the policy making of the government.

Nowadays research collaboration between the business, academic and governmental community is high on the policy agenda in all over the world, especially with regard to science-based technological innovation. The aim of this paper is to explore some of the changing spatial patterns of research collaboration by carrying out bibliometric analysis of co-authorship publications in major international and scientific journals that are jointly realized by Korean scientists and researchers in the seven science-based technologies for the period 2002~2012. Using the co-authored papers as an indicator of research collaboration with the institutional address of each co-authoring researcher and the geographic location of their affiliation, this paper describes some trends and patterns of domestic and international research collaborations. Identifying a rapid increase in the volume of co-authored papers and the trend towards multiple authorships over the last decade, the paper finds collaborative scientific research to be geographically dispersed at the different spatial scales. Despite the rising geographic dispersion of research collaboration within the nation, this paper finds that there were empirical evidences for the presence of localized knowledge production processes at regional level, and biased knowledge flows towards core areas with advanced research resources.

This paper examines the performance according to the combination pattern of HRM and business strategy. The business strategy was divided into Miles & Snow's prospector, defender, and analyzer. Data were collected from the Korea Labor Institute's workplace panel survey from 2005 to 2015, and the analysis used 465 companies that are common respondents of the six wave surveys. To test the research model, structural equation modeling was employed. The results of the analysis showed that the combination of high commitment HRM and prospector had a positively significant effect on the performance. Contrariwise, the combination of high commitment HRM and defender, the combination of high commitment HRM and analyzer were not significant effect on performance.

We introduce various methods to investigate the relations between innovation of technology and social changes by analyzing more than 4 millions of patents registered at United States Patent and Trademark Office(USPTO) from year 1985 to 2015. First, we review the history of patent law and its relation with the quantitative changes of registered patents. Second, we investigate the differences of technical innovations of several countries by use of cluster analysis based on the numbers of registered patents at several technical sectors. Third, we introduce the PageRank algorithm to define important nodes in network type data and apply the PageRank algorithm to find important technical sectors based on citation information between registered patents. Finally, we explain how to use the canonical correlation analysis to study relationship between technical innovation and social changes.

산업성장 잠재력과 기술개발과의 관계는 기술개발을 통해 산업이 어떻게 성장될 수 있는가를 보여주는 관계를 말한다. 첫째는, 산업의 출현(Emergence)이다. 이는 기술개발에 의해 새로운 산업이 발달되는 경우를 말한다. Microcomputer의 출현이 그 대표적 예이다. 둘째, 산업의 재생(Revitalization) 이다. 하향곡선을 그리는 산업이 기술혁신을 통해 새로운 마켓을 개척하여 다시 활기를 띄게 되는 경우이다. 전자 장난감이 장난감 시장의 활성화를 가져온 경우가 이에 속한다. 셋째, 산업의 대체(Substitution)현상은 기술개발에 의해 기존의 산업이 새로운 산업으로 대체되는 경우를 말한다. 진공관 이 트랜지스터를 대체된 경우나 LP가 Compact Disc등으로 대체된 경우도 이에 속한다. 마지막으로, 산업의 퇴보(Decline)는 기술의 개발이 오히려 산업자체의 퇴보나 침체를 가져오는 경우를 말한다. 마모에 저항력이 강한 고무가 타이어산업의 침체를 간져온 경우가 이에 속한다. 본 논문은 과거 10여 년간의 한국의 각종 기업의 기술개발 사례를 통해 이러한 4가지 패턴의 산업성장잠재력에 그러한 기술개발이 어떠한 역할을 하여 왔는가를 규명하고, 한국기업의 기술개발 현황파악을 통한 당면한 문제점을 분석한다. 아울러 한국의 기업들이 한국적 경제 및 경영 환경하에서 어떠한 기술개발과 혁신을 통해 산업성장 잠재력에 기여할 수 있는가를 토론한다.

Bioindustry is rapidly changing. Many biologists redefine biotechnlolgy as 'reprogramming the genetic codes of living things to suit cultural and economic needs and desires.'We regarded this change as the 'paradigm shift'in bioindustry. The genome research is reorganizing agricultural and environmental industries as well as a pharmaceutical industry. By analysing patent data granted in the United States from 1997 to 1999, we tried to explore the international patterns and trends of technological innovation in bioindustry, especially in the genome research. As the result, we could find that the United States'monopolistic position in the bioindustry was consolidated by the genome research. Competitive positions in the countries such as Japan and Germany, however, have been aggravated continuously. Korean inventors weren't also active in many biotechnological areas as comparing to developed countries such as US and UK. Especially, the gaps between Korea and developed countries in genome research were greater than any other areas.
