대량생산을 야기 시킨 산업혁명은 공장주의 재산을 급속도로 부강하게 하는 한편 노동자의 생활 질을 급소도로 저하시켰다. 즉, 노동자들은 기계의 ‘손’역활을 하는 정도로 인격적으로 타락되었으며, 분업작업은 이들로부터 사고력마저 빼앗아 가게되는 실정에 이르렀다. 이익에 눈이 어두어 지게 된 공장주들은 노동임금을 최하로 저하시키고, 노동시설을 비롯해 자본투자를 최소한으로 줄이려는 데서 디자인 질의 격하현상을 초래했다. 즉, 창조적인 디자인 개발 대신에 다른 나라(특히 불란서)의 것을 모방하거나, 기존에 왔던 디자인들을 모방하는데 그치지 않았을 뿐 아니라, 롤러 프린트 사이즈에 맞게 기존된 디자인을 수정하는 작업이 디자이너가 아닌 직공에 의해 이루어지다 보니 그 난잡함은 이루 말 할 수 없을 정도였다. 푸긴과 러스틴은 각자의 작품에 대해 긍지를 지녔던 중세기의 장인제도로 돌아가자고 외쳤고, 러스킨의 아이디어를 철저히 계승받은 윌리암 모리스는 순수예술 못지않는 가치를 장식예술에 부여했으며, 건축이 모든 장식예술의 정점이라고 주장했다. 러스킨과 모리스의 정신을 이어받아 차세대의 건축가/디자이너들은 디자인의 질을 향상시키고, 디자이너의 위치를 화가나 조각가의 위치로 부각시키기 위한 끊임없는 노력을 통해,‘예술/공예 전시협회’를 창설해 오리지널한 장식예술품을 창조하도록 분위기를 조성했을 뿐만 아니라, 강여회와 저서들을 통해 디자이너 자신들과 산업체와 국민들을 교육시켰다. 맥머도, 보이지, 데이, 크레인, 하이테, 버터필드 등은 특히 벽지나 텍 스타일 디자인 등 패턴 디자인 분야에 관심을 보였다. 독창적이고 참신한 이들의 디자인들은 국내의 디자인 질을 향상시켰을 뿐만 아니고, 디자인사의 새 장을 열게끔 한 계기가 되었다.

Many countries are increasing their investments in smart grid technology to enhance energy efficiency, address climate change, and trigger a green energy revolution. In addition to these goals, Korea also seeks to promote national competitiveness, prepare for the growth of the renewable energy industry, and export industrialization through its strategic promotion of the smart grid. Given its inherent representativeness for Korean implementation of the smart grid and its growth potential, Jeju Island was selected by the Korean government as the site for smart grid testing in June 2009. This paper presents a new design for the electricity market and an operational scheme for testing Smart Electricity Services in the Jeju smart grid demonstration project. The Jeju smart grid test-bed electricity market is constructed on the basis of day-ahead and real-time markets to provide two-way electricity transaction environments. The experience of the test-bed market operation shows that the competitive electricity market can facilitate the smart grid deployment in Korea by allowing various demand side resources to be active market players.

Before the industrial revolution architecture has been shaped by the natural and cultural inputs. Local constraints become more effective determinants of architecture in the rural contexts because by being disengaged from the webs of transportation and communication, rural settlements have achieved sustainability in difficult conditions. The examples of rural settlement and architecture have provided sustainability through integration with natural inputs within the geographical context because they have reached the goals of ecological design within the local constraints. Although this feature of the rural cultural landscapes has been emphasized frequently, tangible standards could not be developed in order to interpret their ecological design principles from the perspectives of the contemporary building sector and planning. However, the historical experience indicates that the sustenance of ecological performance can be possible as a result of integrated planning at the overall scale of the settlement. Therefore, the existing standards are not qualified for interpreting the rural contexts. This study develops a method for analysing, interpreting and evaluating traditional rural settlements and certifying new implementations in the rural environments in the light of the given literature review, discussion and methodological proposal.

The DC motor of a vehicle may cause noise and vibration due to high-speed revolution, which can make a driver feel uncomfortable. There have been various studies attempting to solve these problems, mostly focusing on the causes of noise and vibration and a means of preventing them. The CAE methodology is more efficient than a real test for the purpose of looking for various design parameters to reduce the noise and vibration of the DC motor. In this study, a design process for reducing brush noise is presented with the use of a computer model, which is made by using a multi-body dynamics program (DADS). The design parameters to reduce the brush noise and vibration were proposed using a computer model. They were used to reduce the noise and vibration of the DC motor and verified by the test results of the fan DC motor in the vehicle. This method may be applicable to various DC motors.

The change of society causes the change of art necessarily. The experiments of plastic art which as been done by avant-garde movements at early 20th century have pursued ″Object drama″ consistently as trials of more or less abstract drama. As these plastic arts have used genre or media like circuses, sports, variate, films, screen play, newspapers and a quick method which had not been considered suitable for conventional aesthetic plastic arts, these arts looked provocative and, these provocative plastic arts have ignored universality shown in conventional arts and have caused extreme ″sensation″ accordingly. As a result, abstract art based on style which is against aestheticism and naturalism has been generalized. This style does not deny customary laws of art wholly but it requires new concept. Having ignored traditional styles, a new compositive and responsive way of composition which does not deviate from tradition has been pursued. A new and general understanding of arts which do not deny all conventionally-effective standards extremely has been developed. In this regard, this study analyzes characteristics of Bauhaus Theater which has tried to apply new technology engineering to plastic art as an integrated concept of art and technology amongst the directions of development of provocation, innovation and revolution in case of the plastic art of stage painting, and analyzes how this influences on modern painting in terms of avant-garde arts reviewing the meaning of this theory.

기동하는 잠수함이나 함정 등의 방사 소음 특성은 토날 신호와 광대역 배경잡음으로 구분된다. 토날 신호는 함정의 모터나 엔진의 회전등으로 인한 것이고, 배경잡음은 기동 시 일어나는 함정 주변의 기포들의 발생과 소멸로 인한 것이다. 본 연구에서는 ATW 알고리즘을 이용하여 수중 기동함정의 방사소음을 분석한다. 또한 분석한 소음을 바탕으로 힐버트 변환을 이용하여 광대역 유사 잡음을 발생시킬 수 있는 시스템을 설계하고 분석한 토날 신호를 합성함으로써 유사 방사 잡음 발생 시스템을 설계한다. 이 시스템은 현장 기동함정과 유사한 소음을 발생시키게 함으로써 적으로부터 아군의 함정이 노출되었을 때 기만기로 사용함으로써 적의 어뢰 등의 공격을 피할 수 있는 시스템으로 활용할 수 있을 것이다.

Through staggering advancements of technology and network as we know them as digital revolution, we have established a foundation of space in which we can express reality by eliminating the boundaries between expression, space, and movement. There are many ongoing approaches that aim to overcome the physically-fixed property of space where the mathematical-geometric notion of Voronoi Diagram is one of them. Although the repetitive increment based on self-organization during the process in which space is generated by the Voronoi Diagram forms a pattern and focuses on the formation, its pattern is not restricted to a single method of expression but evolves over self-control. The result of having analyzed spaces generated by the Voronoi Diagram in this study can be summarized as follows. First, the Voronoi computation method with self-organization property creates multiple levels, increments, and evolves through feedbacks among changes with the slightest order and in the absence of control. Secondly, after forming a pattern through such feedbacks comes the differentiation phase due to the presence of different properties. Thirdly, a space that has gone through the generation process retransforms through active interaction between changes and it obtains ambiguous boundaries and a repetitive pattern. This leads to an evolution of space through repetitive increments based on self-organization. Such flexible space creation is supported by various digital technologies where we believe a converging application of these studies, sciences, engineering concepts, and space design is and effective and new method in terms of space creation.

Reverse engineering involves duplicating a physical part by measuring and analyzing its physical dimensions, features, and material properties. By combining reverse engineering with three-dimensional (3D) printing, engineers can simply fabricate and evaluate functional prototypes. This design methodology has been attracting increasing interest with the advent of the Fourth Industrial Revolution. In the present study, we apply reverse engineering and 3D printing technologies to evaluate a fabricated automotive inner ring prototype. Through 3D printing, inner rings of various densities were prepared. Their physical dimensions were measured with a 3D scanning system. Of our interest was the effect of inner ring density on the physical dimensions of the fabricated prototype. We compared the design dimensions and physical dimensions of the fabricated prototypes. The results revealed that even the 20% density of inner ring was effective for 3D printing in terms of satisfying the design requirements.
