Due to development of digital technology, a concept of stage design management is being changed. In addition, stage management technique is changing a viewpoint of the audience watching a stage through the convergence of analogue and digital technology. Three-dimensional media such as LED and hologram and works combining with previous stage performances are rising, and the audience's requirements about spectacles on the stage are increasingly higher. Interaction between a stage, audiences and actors is a communication tool by a work story and its direction. In other words, stage design should newly focus on not only concluded work story but also comprehensive delivery of direction and the expression and extreme delivery. Therefore, this study aims to examine how to combine analogue and digital direction elements in the stage design. To this end, this study looks into everything the audience feels through performances and analogue and digital elements directed for performances and then analyzes and arranges them to present a possibility of various types of work performances. Stage structure, set, and lighting that are analogue direction elements are the basis of stage performance. Analogue direction elements mean a media vehicle that can differentiate except for basic direction of each work. This study aims to analyze new performance culture when analog and digital direction elements are combined through stage performance and a possibility of new stage performance. In addition, through this it desired to seek for a development possibility of Korean leisure culture and art culture. As the work cases, this study shows 10 works through actual stage performances held in Korea and introduces elements directed in those works.

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.

One of the highly reliable object tracking methods is to trace objects by associating objects detected by deep learning. The detected object is represented by a rectangular box. The box has information such as location and size. Since the tracker has motion information of the object in addition to the location and size, knowing additional information about the motion of the detected box can increase the reliability of object tracking. In this paper, we present a new method of reliably estimating the moving direction of the detected object in underground parking lot. First, the frame difference image is binarized for detecting motion energy, change due to the object motion. Then, a cumulative binary image is generated that shows how the motion energy changes over time. Next, the moving direction of the detected box is estimated from the accumulated image. We use a new cost function to accurately estimate the direction of movement of the detected box. The proposed method proves its performance through comparative experiments of the existing methods.

A new computationally efficient algorithm-based propagator method for two-dimensional (2-D) direction-of-arrival (DOA) estimation is proposed, which uses two parallel uniform linear arrays. The algorithm takes advantage of the special structure of the array which enables 2-D DOA estimation without pair matching. Simulation results show that the proposed algorithm achieves very accurate estimation at a computational cost 4 dB lower than that of standard methods.

Yield and fracture are separated in the tensile failure of paper. Failure in the machine direction of photocopy paper is contrasted with failure in the cross-machine direction . The ratios of distortion (shape change) to dilatation (volume change) for individual elements at yield and fracture are described. The ratios of distortion to dilatation are measured and compared to predicted values of the strain energy density theory. To evaluate the effect of the angle from the principal material direction on the strain energy density theory. To evaluate the effect of the angle from the principal material direction on the strain energy density factor, samples are prepared from machine direction to cross-machine direction in 15 degree intervals. the strain energy density of individual elements are obtained by the integration of stress from finite element analysis with elastic plus plastic strain energy density theory. Poison's ratio and the angle from the principal material direction have a great effect ion the ratio fo distortion to dilatation in paper. During the yield condition, distortion prevails over dilatation . At fracture, dilatation is at a maximum.

This paper presents a new geometric morphing algorithm for polygons based on a simple geometric structure called direction map, which is mainly composed of a circular list of direction vectors defined by two neighboring vertices of a polygon. To generate a sequence of intermediate morphing shapes, first we merge direction maps of given control shapes based on a certain ordering rule of direction vectors, and scale the length of each direction vectors using Bezier or blossom controls. We show that the proposed algorithm is an improvement of the previous methods based on Minkowski sum (or convolution) in th aspects of computational efficiency and geometric properties.

In this paper, a new method is proposed for tracking the direction-of-arrival (DOA) of the wideband moving source incident on uniform linear array sensors. DOA is estimated by focusing transformation matrices. To update focusing matrices along with new data snap shots, we use the FAST (Fast Approximate Subspace Tracking) method. Present focusing matrices are constructed by previous signal and its orthogonal basis vectors as well as present signal and its orthogonal basis vectors, which are the left and right singular vectors of the inner product of two approximated matrices. Simulation results are shown to illustrate the performance of the proposed method.

In this paper, we propose a new method to stable simulation the directional ice shape by coupling of freezing solver and viscous water flow. The proposed ice modeling framework considers viscous fluid flow in the direction of ice growth, which is important in freezing simulation. The water simulation solution uses the method of applying a new viscous technique to the IISPH(Implicit incompressible SPH) simulation, and the ice direction and the glaze effect use the proposed anisotropic freezing solution. The condition in which water particles change state to ice particles is calculated as a function of humidity and new energy with water flow. Humidity approximates a virtual water film on the surface of the object, and fluid flow is incorporated into our anisotropic freezing solution to guide the growth direction of ice. As a result, the results of the glaze and directional freezing simulations are shown stably according to the flow direction of viscous water.

In an opportunistic network, one of the most challenging issues is the equilibrium of the network traffic and transmission delay for forwarding messages. To resolve this problem, we propose a new forwarding scheme, called the direction entropy-based forwarding scheme (DEFS), using the main direction and direction entropy based on the information collected about the directions of the nodes in the network. Since each node sends a message to another node with a different location and less direction entropy, DEFS utilizes those nodes that are more likely to travel to various locations to forward the messages to the destination nodes. Experiments were performed on the network simulator NS-2. The results show that DEFS provides better balance than the typical forwarding schemes, such as Epidemic, PRoPHET, and WAIT.
