인간과 상호작용하는 로봇의 경우, 자연스러운 움직임과 행동은 사람에게 친근감을 제공한다. 그러한 자연스러운 움직임과 행동의 기반이 되는 요소기술들 중 하나로 음원추적을 꼽을 수 있다. 본 논문에서는 3개의 마이크를 장착한 로봇에서의 시간지연기반 음원추적 시스템에 대해 소개한다. 개발된 음원추적 시스템을 지능형 서비스 로봇 WEVER-R2에 적용한 결과, 에러율 ${\pm}15$도 이내에서 93% 이상의 성공률을 보였다.

This study investigated relationships between engagement in joint attention and the early language development in infancy. Subjects were 12 infants and their mothers. At 20 and 25 months of age, each child's spontaneous natural speech during interaction with his/her caregiver was videotaped for about 30 minutes. The EJA(Episodes of joint attention) focus between mother and child were identified and coded by Tomasello and Todd's(1983) and Bakeman and Adamson's(1984) including person engagement, object engagement, looking engagement, passive joint attention, coordinated joint attention. Results showed that a significant difference in infant's language development between within and outside EJA at 20 and 25 months of age; that is, during periods of EJA children talked more inside than outside EJA.

This study was conducted to identify relationships between toddler-teacher joint attention and toddlers' vocabularies. Toddlers' vocabularies were assessed by the MacArthur Communicative Development Inventory-Korean (MCDI-K) modified by Kim (2006); joint attention episodes were observed by classification categories for engagement condition (Bakeman & Adamson, 1984). Data were analyzed by means, t-test and Pearson's correlations. Results were that : (1) receptive vocabulary of toddlers was about 1.1 times as high as their expressive vocabulary. (2) Coordinated joint attention was observed most frequently, followed by supported joint attention; coordinated joint attention was closely related to support joint attention. (3) The relationship between toddler-teacher joint attention and toddlers' vocabularies were significant in a positive direction.

오늘날과 같이 급변하는 사회 속에서 개인 혼자서 모든 일을 처리하기보다는 여러 사람과 함께 열린 사고로 일을 처리하는 것이 훨씬 효율적이다. 학습에서도 마찬가지로 협동학습은 지식뿐만 아니라 인성적인 면에도 영향을 끼치게 된다. 본 논문에서는 구성주의에 입각한 웹기반 협동학습 시스템을 설계 및 구현하여 실제 학습 수업에서 활용한다. 이 시스템에서는 학습내용을 구성하는 부분과 이를 이용하여 학습을 수행하는 부분들이 교수자간 및 학습자간에 협동을 한다. 이는 고차원적인 사고를 요구하는 문제해결학습을 통해 학습자 개개인의 능력을 최대한 개발할 수 있고, 학습 성취감을 증가시킬 수 있다. 또한 그동안 부족했던 웹상에서의 상호작용적인 측면을 강화하여 면대면 교육과 같은 즉각적인 효과도 얻을 수 있다.

3차원 포인트 클라우드의 의미적 분할은 환경을 구성하는 물체 단위로 포인트 클라우드를 분할하는 작업으로서, 환경의 3차원적 구성을 이해하고 환경과 상호작용에 필수적인 시각 지능을 요구한다. 본 논문에서는 포인트 클라우드에서 추출하는 3차원 기하학적 특징과 함께 멀티-뷰 영상에서 추출하는 2차원 시각적 특징들도 활용하는 새로운 3차원 포인트 클라우드 의미적 분할 모델 MFNet을 제안한다. 제안 모델은 서로 이질적인 2차원 시각적 특징과 3차원 기하학적 특징의 효과적인 융합을 위해, 새로운 중기 융합 전략과 멀티-모달 교차 주의집중을 이용한다. 본 논문에서는 ScanNetV2 벤치마크 데이터 집합을 이용한 다양한 실험들을 통해, 제안 모델 MFNet의 우수성을 입증한다.

This paper aims at dealing with the communication of Korean gong sound. It is based on 'music-spirit theory' of Han-Gi Choi and Mead's 'symbolic interactionism', and does this by interpreting the message of gong sound that is mentioned in Korean literature. The gong sound brings out the message of symbolizing evaporation of Korean people's joy and regrettable matters in the playing yard by regulating of breathing according to the steps. By the novel "Gong Sound" of Sun-Tae Moon Korean gong sound has a message of people's joy, anger, avarice, anxiety and sorrow. In Jeong-Rae Jo's novel "Arirang" the Korean Gong Sound includes a message of evaporation of people's regret and raises the national spirit during the Japanese Imperialism. By Jeong-Ja Yoo's collection of poems, "The sound of flower breathing carried by gong sound", the Korean gong sound carries a message of a roar of spirit and breathing of the spring flower. In conclusion, the Korean gong sound is a sublime sound of sky which carries the message of symbolizing evaporation of people's joy and regrettable matters through the sound communication in the open space, and awakes us to a method of breathing with sky.

The study was carried out to analyze election regionalism and to find out the spatial pattern of party support drawn in the 18th general election. Strongly biased pattern found to be caused by party strategies and voting behaviour preferring for the local party. Each party employed the strategies such as tactical and nepotic nomination, regional development pledges, and local instigation of regionalism. In consciousness survey done by the National Election Commission, primarily people tend to choose the representative by his(her) party and secondly, they consider their carrier and occupation. They vote for the same party in the local district and proportional representation. While election regionalism strongly found in voting behaviour of each party's main strongholds based on spatial pattern of major party support, voters of Seoul and Chungbuk tend to vote for their interests due to regional development pledges such as 'Newtown' Development and 'Multifunctional Administrative City' construction.

This study examines the effect of general corporate employees' perception of organizational politics, which is widespread and negatively perceived in Korean companies, on their reaction behavior. In particular, the mediating effect of cynicism and the moderating effect of commitment was analyzed. As a result of the analysis, it was confirmed that organizational political perception had a positive effect on cynicism, and cynicism had a significant effect on exit, loyalty, and neglect. In addition, the moderating effect of commitment between cynicism, exit, and neglect was confirmed. Through this study, it was demonstrated that the higher the organizational political perception, the higher the cynicism and the negative reaction behavior. It was intended to suggest the organizational system improvement and the importance of human resource management through it.

This study is to critically examine a variety of perspectives of seeing the interactions among space, people, and society. According to Tuan, place is a center of meaning constructed by people's experience, and its attributes consist of natural and built-up environments. Entrikin suggests a way of seeing place from a contrary perspective, that is, the subjective and existential sense of place and the objective and naturalistic conception of place. Lefebvre examines the historical transformation of social space through the dialectics among the perceived space, the conceived space, and the lived space. Social space is (re)produced and changed through the conflictual unit of the spatial triad. The project of Foucault's spatial metaphor is to tightly combine three critical concepts, power, knowledge, and space. Those concepts are not objectively existed regardless of specific times and spaces, but they are socially and culturally constructed through the networks of people under particular environments. In the following papers, it is needed to comparatively examine the various perspectives mentioned above to make a new conceptual framework of understanding the interactions among space, people, and society.
