The purpose of this study is to grope the direction of the environmental movement for the improvement of welfare. The deterioration of environment which was resulted from the development of material civilization due to the industrialization made people newly recognize the importance of environment. The quality of the future life depends on the solution of the environmental problems. The family-centered environmental movement as a new cultural movement in the daily life should be revitalized for the purpose of improving welfare. This study investigated the several views on the environmental problems in the neighboring disciplines of home economics. And on the basis of the results of the study, the direction of environmental movement to be developed in home economics was represented. This study represented the directions of the environmental movement as a new cultural movement in the daily life as follows: alternative life-style, that is, pro-environmental life-style-oriented direction; community-oriented direction such as cooperative association movement in daily life; the politicalization of the environmental problems, that is, the endeavor to reflect the election promise on the environment in the vote, etc. The content of the environmental movement shoed be treated of in environmental education, consumer education, family-life education, school education, and life-long education.

이 논문은 실험적 단편 애니메이션에서 나타나는 조절된 움직임을 통해 영화의 운동 이미지가 특징적으로 드러남을 연구하였다. 애니메이션은 실사 영화의 쇼트 편집에서 나아가 프레임 사이의 관계를 재정의 하는 방식으로 운동 이미지에 대한 보다 적극적인 개입을 하게 된다. 애니메이션에서 운동은 단지 기법적인 것만이 아니라 애니메이션을 인지하고 감정을 불러일으키는 애니메이션의 본질적인 부분이며 개별 애니메이션의 의미를 드러내는 중심이라는 것을 운동 이미지라는 개념을 통해 이야기 하고 있다.

When a construction company builds a high structure, many piles should be driven into the ground by a hammer whose weight is 7,000 Kg in order to make the ground under the structure safe and strong. So, it is essential to determine whether a pile is penetrated into the ground enough to support the weight of the structure since ground characteristics at different locations are different each other. This paper proposes a visual measurement system for pile rebound and penetration movement including vibration using a high-speed line-scan camera and a specially designed mark to recognize two-dimensional motion parameters of the mark using only a line-scan camera. A mark stacking white and black right-angled triangles is used for the measurement, and movement information for vertical distance, horizontal distance and rotational angle is determined simultaneously

In this thesis, the recognition method of the movement of an 3D object is presented. The information about the movement of a 3D object is used to recognize the object. There are 2 kinds of movements which are translation and rotation. A difference picture is obtained from a sequence of images of a moving object or a scene which is taken by a monocular stationary observer. The 3D movement of an object is recognized by the Artificial Neural Network(ANN) using the difference picture.

When people recognize a landscape, they first need to see it for a definite period time. This study clarified the way green space in a landscape is recognized using eye movement analysis, and evaluated the Pffi9bility for quantifying stress-reducing effects of seeing a landscape. The results of the experiments on eye movement analysis suggest that the way of recognizing green space in a landscape may depend on a ratio of the amount of scenic greenery in a landscape, color and greenery layout. Especially, this study also suggests that the possibility of the greenery layout guiding eye movement could be verified by conducting a study on planting patterns. In addition, the results of the experiments for quantifying stress-reducing substances found that it is likely that a green space in an urban area has stress-reducing effects.

본 논문은 복잡한 배경에서 표식없는 손을 추적하여 한글 수화를 인식하는 시스템에 관한 것이다. 제안한 방법은 먼저 인접한 프레임간의 차 영상에 대하여 엔트로피를 측정한다. 큰 값을 갖는 영역에 대해 피부색에 가까운 분포를 갖는 색상 정보를 추출하여 배경 영상으로부터 손 영역만을 추출한다. 추출된 손 영역에 대해 윤곽선을 검출하고 개선된 무게중심 프로필(centroidal profile) 방법을 적용하여 수화를 인식한다. 6가지 모양의 수화를 사용한 실험결과 기존의 방법들과 달리 표식을 사용하지 않고도 복잡한 배경과 조명의 변화에서 안정적으로 수화를 인식할 수 있다. 또한 초당 15프레임 정도의 처리속도로 각 사람별로 95%이상, 각 수화별로 $90\sim100%$의 인식률을 얻을 수 있다.

In this paper, we propose the adaptation filtering for correcting the movement path of the recognized object by the depth information. When we recognize the object by the depth information, the path error should be occurred because of the noises in the depth information. The path error is corrected by appling the lowpass filtering, but the lowpass filtering is not efficient when the changes of the object's movement are rapid. In this paper, we apply the adaptation filtering that it gives weights adaptively as the difference between the predicted location and the measured location. To apply the adaptation filtering, we can see that the proposed method can correct accurately the path error of the radical change from simulation results.

This paper introduces a method to control an industrial robot arm to imitate the movement of the human arm and hand using electromyography (EMG) signals. The proposed method is implemented on the UR3 robot that is a popular industrial robot and a MYO armband that measure the EMG signals generated by human muscles. The communications for the UR3 robot and the MYO armband are integrated in the robot operating system (ROS) that is a middle-ware to develop robot systems easily. The movement of the human arm and hand is detected by the MYO armband, which is utilized to recognize and to estimate the speed of the movement of the operator's arm and the motion of the operator's hand. The proposed system can be easily used when human's detailed movement is required in the environment where human can't work. An experiments have been conducted to verify the performance of the proposed method using the teleoperation of the UR3 robot.

Traffic safety issues have recently been seriously magnified, due to child deaths in apartment complexes and parking lots. Accordingly, traffic safety technologies are being developed to recognize dangerous situations on living roads and to provide warning services. In this study, a collision detection algorithm was developed to prevent collision accidents between moving objects, by using object type and location information provided from CCTV monitoring devices. To determine the exact collision between moving objects, an object movement model was developed to predict the range of movement by considering the moving characteristics of the object, and a collision detection algorithm was developed to efficiently analyze the presence and location of the collision. The developed object movement model as well as the collision detection algorithm were simulated, in a virtual space of an actual living road to verify performance and derive supplementary matters.
