최근 들어 고성능 비행 드론이 주목받고 있다. 특히, 다중 로터를 장착한 헬기 형태의 비행 드론은 항공촬영, 방송영상제작, 항공구조, 물류배송, 감시, 측량, 방역 방제, 군사용 등으로 그 활용범위를 확장해가고 있다. 그러나 이를 조종하는 제어기의 형태는 매우 단순하다. 따라서 본 연구에서는 모바일 기기에 탑재된 G-센서를 이용하여 사용자의 직관적인 동작으로 비행 드론을 조종할 수 있는 향상된 제어기를 구현한다. 구현된 제어기는 신경망 알고리즘을 사용하여 동작 인식 성능을 향상시켰다.

In recent years, high-performance flying drones attract attention for many peoples. In particular, the drone equipped with multi-rotor is expanding its range of utilization in video imaging, aerial rescue, logistics, monitoring, measurement, military field, etc. However, the control function of its controller is very simple. In this study, using a G-sensor mounted on a mobile device, implements an enhanced controller to control flying drones through the intuitive gesture of user. The implemented controller improves the gesture recognition performance using a neural network algorithm.

본 연구에서는 외모수용과 섭식통제상실의 관계에서 직관적 섭식이 가지는 매개효과와 내수용자각의 조절효과를 통합적으로 검증하고자 하였다. 국내 대학생 316명을 대상으로 외모수용, 섭식통제상실, 직관적 섭식, 내수용자각을 측정하는 자기보고식 설문을 실시하였다. 분석 결과, 외모수용과 섭식통제상실의 관계를 직관적 섭식이 완전매개한다는 것이 확인되었다. 즉, 외모수용의 수준이 높은 사람은 직관적 섭식을 행하여, 섭식통제상실을 덜 경험하게 된다고 볼 수 있다. 다음으로 외모수용과 직관적 섭식의 관계에서 내수용자각이 조절효과를 보인다는 것이 확인되었다. 마지막으로 외모수용과 섭식통제상실의 관계를 직관적 섭식이 매개하고, 이러한 매개효과가 내수용자각의 수준에 따라서 변화한다는 결과를 확인했다. 즉, 연구의 최종모형인 조절된 매개모형이 유의한 것으로 확인됐다. 이는 외모수용의 수준이 높을수록 직관적 섭식이 증가하여 섭식통제상실을 덜 경험하게 되는데, 내수용자각의 수준이 높을수록 이러한 관계는 더욱 강화된다는 것을 의미한다. 이러한 연구 결과는 외모수용과 직관적 섭식이 섭식통제상실을 완화 및 예방하는 효과를 보이고, 이 과정에서 내수용자각은 이러한 효과를 강화시켜주는 것임을 시사한다.

The purpose of this study was to examine the role of intuitive eating and interoceptive awareness on the relationship between appearance appreciation and loss of control over eating. Specifically, we explored the moderated mediating effect of interoceptive awareness on the relationship between appearance appreciation and loss of control over eating through intuitive eating. A total of 316 undergraduate and graduate students completed self-report questionnaires including appearance appreciation, loss of control over eating, intuitive eating, and interoceptive awareness. The results showed that the mediation effect of intuitive eating between appearance appreciation and loss of control over eating was significant, as well as the moderation effect of interoceptive awareness between appearance appreciation and intuitive eating. The effect of appearance appreciation on intuitive eating was different according to the level of interoceptive awareness. Finally, the moderated mediation effect of intuitive eating and interoceptive awareness was significant. These findings suggest that intuitive eating mediates the relationship between appearance appreciation and loss of control over eating, and self-compassion moderates it.

Civil engineering construction work has always been accompanied by a high proportion of tasks that are either dangerous or unpleasant or both. Enhancing the general working environment and boosting safety levels are critical issues for the industry. In addition to that, the industry has been slow to utilize automation & robot technology, and there is substantial scope for the use of technology th boost efficiency, cut costs and improve quality levels in construction. In a bid to address this issue, Ministry of Construction & Transportation launched a five-year project in 2003 entitled Development of Intelligent Excavating System. The aim of the project is to use telecommunications and robotics technology to minimize inefficiencies and eliminate the dangerous and unpleasant aspects of tile construction process through the development of specific applications such as IT-equipped construction machinery and advanced construction management systems. In this paper, the project introduces on the research and development content related to multi-disciplinary, a intuitive operator control unit(Robot Technology) included.
