Arts have changed continuously reflecting the times with the political atmosphere and social systems. As political, economic, and social big changes have occurred since World War II, antihistorical tendencies rejecting modernism in the early 20th century have come to appear in culture and arts as well. With these social changes, radical, avant-garde and artistic tendencies with strong experimental spirits, which rejected modernism took place especially in American dancing world. Trends of improvised elements and experimental trials were dominated discovering expressions of new movements in intentions and expressions of works. The purpose of this study is to investigate the effects on choreographic forms of modern dance until today by exploring choreographic characteristics of this postmodernism. To examine post-modernist inclinations in works, Trisha Brown who led American post-modern dance stressed dance for expressions of movements in themselves and pure movements by actively accepting into dance works American social flows which played a major role in postmodernism starting from 1960s. American modern dancers considered body in itself as important one and any emotional expressions and individual sensitivity is excluded as their physical expressions are factual, realistic, and due to their movements. They imprinted dance as valuable art by recreating ordinary behaviors into dance, using space excellently and forming experimental dance shapes. Therefore, it can be said that through analyzing brown's works, we proposed a new direction getting out of limits of arts and provided a direction of essential dance alt to movements of modern dance and choreographic shapes.

Remarshalling operation is one of the operations considered important in an automated container terminal to perform quickly loading operations and delivery operations. It arranges the containers scattered at a verticla yard block in order to reduce the transfer time and the rehandling time of ATC(Automated Transfer Crane)s. This paper deals with the remarshalling planning problem minimizing the weighted operation time. This problem can be decomposed into 2 subproblems, storage space assignment problem and operation sequencing problem Storage space assignment problem decides to where containers are transported in terms of transportation time cost.. With results of a previous subproblem, operation sequence problem determines the ATC operation sequence, which minimizes the dead-heading of ATC This study formulates each subproblem with mixed integer program and dynamic program. To illustrate the proposed model, we propose an instance to explain the process of remarshalling planning.

In this paper, we describe an algorithm which can automatically recognize human gesture for Human-Robot interaction. In early works, many systems for recognizing human gestures work under many restricted conditions. To eliminate these restrictions, we have proposed the method that can represent 3D and 2D gesture information simultaneously, APM. This method is less sensitive to noise or appearance characteristic. First, the feature vectors are extracted using APM. The next step is constructing a gesture space by analyzing the statistical information of training images with PCA. And then, input images are compared to the model and individually symbolized to one portion of the model space. In the last step, the symbolized images are recognized with HMM as one of model gestures. The experimental results indicate that the proposed algorithm is efficient on gesture recognition, and it is very convenient to apply to humanoid robot or intelligent interface systems.

The sound we hear is transmitted through the atmosphere. However, both the sound we want to hear and the surrounding sound are mixed, and noise is generated, and the sound is not clearly transmitted due to factors such as distance. In particular, in closed spaces like buildings, it is often difficult to hear sounds from outside because of the sound of reflection. People with hearing impairments, such as the elderly and the deaf, have a hard time hearing the sounds they want to hear. Thus, we are developing a hearing aid that can detect radio waves. To this end, we propose the development of a hearing aid that uses FM radio and Bluetooth. These devices are expected to be useful not only for the elderly and the deaf but also in situations where information is transmitted to a large number of people, such as students and tourists, in a large space. The main purpose of this device is to enable users to hear sound correctly without blind spots.

This research deals with the influence of nonlinearities associated with impact and sliding upon the rocking behavior of a rigid block, which is subjected to two-dimensional horizontal and vertical excitation. Nonlinearities in the vibration were found to depend strongly on the effect of the impact between the block and the base, which involves an abrupt reduction in the system's kinetic energy. In particular, when sliding occurs, the rocking behavior is substantially changed. Response analysis using a non-dimensional rocking equation was carried out for a variety of excitation levels and excitation frequencies. The chaos responses were observed over a wide response region, particularly, in the cases of high vertical displacement and violent sliding motion, and the chaos characteristics appear in the time histories, Poincare maps, power spectra and Lyapunov exponents of the rocking responses. The complex behavior of chaotic response, in phase space, is illustrated by the Poincare map. The distribution of the rocking response is described by bifurcation diagrams and the effects of sliding motion are examined through the several rocking response examples.

This study aims at defining the concept of a cyber-geospace and proposing how to establish a cyber-geospace fir the entire country in detail. The study defined the cyber-geospace as 'the dynamic second territory of Korea not only to manage the land systematicality and deal with administrative services for the people in aspect of public sector, but also to contain economic activities of corporations and the citizen's everyday lives in aspect of private sector, in a 3D virtual reality made by digitizing various facilities and buildings as well as the entire toterritory including ground, underground and even sea'. In order to establish such a cyber-geospace, the project should be pursued on the national level fir around ten-year period.

The almost pole transformers are constructed with tank, cover, clamp etc., that contains the insulation oil, core, coil, terminals, bus and the other accessories. If some fault current will be flown by some trouble or accident, interior pressure of the transformer shall be very quickly rise, and mechanical components or insulation oil from the transformer enclosure shall be propelled or dropped from the tank. For the prevention of the above accident, recently the pole transformers should be done 'the Design Tests for Fault Current Capability' according to ANSI C57.12.20(1997) There are two tests method in this standard, Test Number I with a high current arcing fault, without internal fusible elements, shall be conducted on rack enclosure with its minimum designed air space. Test Number II with an internal fusible element, shall be conducted on each enclosure diameter utilizing the internal fusible elements. KEPCO recently request to be done the 'Design Tests for Fault Current Capability' for pole transformers according to KEPCO's standard ES141-$533{\sim}545$, PS141-$482{\sim}518$ and RS141-$611{\sim}628$ that is same with Test Number I of ANSI C57.12.20.

This paper analyzes director Yang Yong-hi's documentary films "Dear Pyongyang"(2006), "Goodbye, Pyongyang"(2009) and her fiction film "Our Homeland"(2012). These films were produced on the base of the director's autobiographical experience, and raise issue of Jainichi-Korean diaspora who be caught in nation-state; North Korea, South Korea and Japan. With the family narratives crossing Jeju, Osaka, and Pyongyang, these films doubt boundaries be set by nation-state, and seek new breakout space. This paper traces restructuring identity in the tensional heterogeneity of nation-state exaction; Integration, unity, uniform education. In conclusion, these films foresee Korean diaspora's future identity from hybrid identities. It shows Korean diaspora's potential of receptivity, openness and solidarity which are required for Northeast Asian peace and the solution of two Korea's hostility.
