본 논문은 컴퓨터 시각을 이용하여 동적 제스쳐를 인식하기 위한 효율적인 지식 표 현 기법의 개발을 목표로 한다. 제스쳐란 시각적인 언어로서 소리를 대신하여 몸짓이나 손 짓을 통하여 자신의 생각이나 의도를 전달하는 보조적인 의사 전달 수단이다. 제안된 기법 은 여러 다양한 지식을 통합하여 총체적으로 표현하기에 적합한 프레임 구조를 기반으로 한 다. 프레임 지식을 물체의 특성을 표현하는 객체 지식, 물체의 움직임을 표현하는 행동 지 식, 그리고 객체 지식과 행동 지식의 순서화 된 집함으로써 동적인 제스쳐를 표현하는 스키 마로 분류한다.

To develop a virtual world-based immersive tutoring system, we would like to develop a simulation in the spatial aspect to maximize the diversity and realism of the situation. This implementation requires the modeling of virtual space as well as the knowledge and intelligent thinking functions of virtual humans. First, information structures are needed to simulate the hierarchical and multifaceted composition of space and the corresponding knowledge of virtual humans. Specifically, four structures for 2.5D spatial distribution expression, complex spatial relationship expression, object expression, and temporal and spatial representation of events are developed respectively. It then uses these expressed knowledge to develop the spatial thinking function of virtual humans needed to make spatial movement. In general, events have a chain effect on adjacent or connected objects through force, resulting in a variety of situations and reflected in the planning of the next action by the virtual humans involved. For this purpose, the development of events according to historical trends is recorded on the representation structure of time and space. It embodies typical events to demonstrate the feasibility of independent behavior in complex spaces among virtual people.

The information technologies industry is now experiencing a rebirth of strong stable growth. However, very few studies have examined performance implications of strategic alliance or merger and acquisition from a knowledge-based view. Furthermore, none of these studies have investigated resource complementarities and alliance or merger and acquisition motive as potential sources of firm performance. This paper extends upon current knowledge-based literature to discover and explore linkages between resource complementarities and firm performance of strategic alliances or merger acquisitions. This study finds that strategic alliance and merger and acquisition announcements have provided abnormal positive returns of production alliances and merger and acquisition. This study can be used as a stepping stone for selection of strategic alliance or merger and acquisition.

Posttraumatic growth literature has been rapidly expanding in multiple academic disciplines. Purpose of this study is to examine the knowledge structure of posttraumatic growth utilizing a network analysis. Papers published between 1996 and 2018 were searched on the Web of Science, focusing on terms related to posttraumatic growth. One thousand six-hundred and fifty-nine keywords were published 6,343 times in 1,780 papers; thus, a total of 322 keywords (5,195 appearances) were selected for the final analysis. The network analysis and network visualization tool used were NodeXL and PFnet, respectively. The keywords which appeared the most frequently were "Posttraumatic growth," followed by "Posttraumatic Stress Disease," "Cancer," and "Trauma." A total of 322 nodes have been reduced to 175 nodes and divided into a total of five groups. The five groups were "Posttraumatic Growth in Cancer, Chronic/Serious Illness, and Disability," "Posttraumatic Growth-related Psychological Variables and Psychotherapy," "Posttraumatic Growth in the Context of Death," "Cognitive Mechanisms of Posttraumatic Growth," and "Vicarious Posttraumatic Growth." This study provides a systematic overview on the knowledge structure of posttraumatic growth by quantitatively network analysis.

This study aims to detect the knowledge structure of Korean studies using document co-citation analysis and text mining techniques. This study divided Korean corpus into two perspectives: Self-perceived and others' perceived Korean studies. To this end, we collected 10,929 humanities and social literature containing the word Korea or Korean as a keyword in the SCOPUS database. As a result of analysis, a total of 20 subdomains were found in the knowledge structure of self-perception, and a total of 14 subdomains were found in the knowledge structure of otherts' perception. Differences in Korean Studies between two are: First, the sub-area of self-perceived Korean studies is subdivided into more diverse areas than the sub-area of other-perceived Korean studies. Second the major areas in self-perceived Korean studies are customers and services, industrialization, multiculturalism, mental health, tourism, Korean language, environment, and cities. Others' perceptions of Korean Studies are grouped into domestic and foreign situations of Korea, Korean pop culture, Koreans as US immigrants, and Korean language. Finally, the common areas of self-perception and others' perception were mental health, tourism, Korean language, North-Korean defectors, and juvenile delinquency.

Upon the growing popularity of knowledge information and paid digital content, the Internet knowledge exchange market had emerged. A Internet knowledge exchange market consists of general characteristics of a market where a wide variety of knowledge is exchanged at market-appropriate prices, the Internet knowledge exchange market is recently gaining momentum with specialized knowledge items such as design, program source, patent information, consulting service, multimedia, or resumes, as it seeks to secure competitive advantage over its peer markets. Considering the immense influence that these Internet markets will exert on the existing system of knowledge circulation including libraries and information centers, this study aims to contribute to a better understanding of Korea's knowledge circulation structure by analyzing the current standing of the Internet knowledge exchange market.

In today's knowledge-based industries, knowledge can be said to be a significant factor that has a decisive impact on corporate competitiveness. Recently, Korean construction companies have been going through a difficult period of time because of various negative domestic and foreign factors, such as economic decline and a continued sluggish domestic construction market, mainly due to the Korean government's real estate regulations and increasing competition from overseas companies with improved technologies. To help domestic construction companies navigate such an environment, this study empirically analyzes how the nature of corporate knowledge impacts the acquisition, transfer and deployment of knowledge within the organization of a company. Through such empirical analysis, we looked into how internal attributes of corporate knowledge affect the acquisition, transfer and application of such knowledge for domestic construction companies, with the application of the structural equation modeling (SEM). According to the results of this study, it is clear that the attributes of corporate knowledge have a significant impact on the acquisition, transfer and application of corporate knowledge, and therefore on the managerial performance of domestic companies.

인간의 지식 표상 규명에 대한 연구는 인간을 대상으로 연구하는 심리학에서뿐만 아니라 인간의 지능을 컴퓨터를 이용하여 구현하고자 하는 인공지능 학문에서도 오래 전부터 매우 중요한 화두가 되고 있다. 특히 인간의 지식 중 언어 지식에 대한 연구는 인간의 언어처리 과정 및 현상을 규명하고 이해하고자 하는 심리언어학에서뿐만 아니라 인간의 언어를 컴퓨터를 이용하여 처리하고자 하는 전산언어학 연구에 있어서도 매우 중요하다. 본 논문은 피험자를 대상으로 한 어절 재인 시 관찰되었던 언어 현상을 설명할 수 있는 시뮬레이션 모델과 이에 근거한 심성어휘집내에서의 한국어 어절의 표상 구조를 제안한다.
