  • In order to solve the contradiction between requirements of high sampling rate for acquiring accurate energy information of pulses and large amount of data to be processed timely, the method with an algorithm to correct errors caused by reducing the sampling rate is normally used in front-end read-out system, which is conductive to extract accurate energy information from digitized waveform of pulse. The functions and effects of algorithms, which mainly include polynomial fitting with different fitting times, double exponential function fitting under different sampling modes, and integral area algorithm, are analyzed and evaluated, and some meaningful results is presented in this paper. The algorithm described in the paper has been used preliminarily in a prototype system of Positron Emission Tomography (PET) for heavy-ion cancer therapy facility.

  • The dense granular flow spallation target is a new target concept proposed for an Accelerator-Driven Sub-critical (ADS) system. In this paper, the beam-target configurations of a tungsten granular flow target for the ADS with a thermal power of 1 GW is explored. The beam profile options using different scanning methods are discussed. The critical geometry parameters are adjusted to investigate the performance of the granular target from the aspects of neutron efficiency, stability and temperature distribution in target medium. To figure out how the target under accident conditions would behave, different clogging conditions are induced in the simulation. The dynamic processes are analyzed and some important parameters such as abnormal temperature rise and beam cutoff time window are obtained. The response of the sub-critical reactor to a clogging accident is also investigated. It is indicated that the monitoring of the granular flow by the neutron detectors in the sub-critical core will be effective.

  • This study was to analyse the meanings of the appropriation inherited in the modern costumes from the latter of the 20th century to the present. According to the dictionary, the meanings of a word. "appropriation" is to steal something, used in order to avoid saying this directly. The sorts of the appropriation represented in the works of Art was as follow : First. the reconstruction by the imitation of the works of a great master or partly induction of the works of a great master Second, the introduction by the history, modern art, the image of popular culture Third, the imitation by the works of photograph, etc The appropriation in the modern costumes could be distinguished as two facts : First, the appropriation of the image of popular culture, 1) the way by the induction of popular factors of the extremely routine, commonplace character 2) the way by the citation of critical sentence of society, complaint message of the situation of times. Second, the reinterpretation of the past works : 1) the way by the reinterpretation of a great artist′s works, or popular works. In accordance with its change of a standard of value of the beauty, the products of modern culture, called the artificial second image, that is, popular factor, ready made factor, a signboard, a trademark etc, was appropriated in modern costumes and was reinterpreted by the works of fashion designer′s empathy. We can say that the modern costumes is not only the products of creative, original action of fashion designers but also the mirror of times, having relationship with society.

  • 본 논문은 디자인 사고에 대한 이해를 바탕으로 모던 디자인 현상에 자리하는 디자인 사고를 고찰하고 있다. 디자인이라는 언어를 통해 일상 삶을 변화시키고자 했던 모던 디자인의 기획은 기하학적 조형과 기능에의 집착, 기계의 적극적 수용 등과 같은 구체적 현상으로 발현되었다. 그 이면에는 '효율과 편리에 대한 집착', '환원된 필요를 기능과 대응시키는 전략', '전문가 시스템을 바탕으로 한 부분의 합이 전체라는 믿음', '사적 공간과 공적 공간을 구분하는 것과 같은 이분법적 사고'들이 자리하고 있다. 수공예적인 생산양식에서 기계적 생산양식으로의 이행과 자아에 대한 인식 등이 가능했던 사회 분위기가 이러한 디자인 사고를 가능하게 하였다.

  • This article aims at rethinking on people of Modern styles in early modern period with reference to A Large River[Dae-Ha] written by Kim Nam-cheon at 1939. Park Sung-guoen could be called to Homo Economicus, first, have maximized of self-interest in rapid changes of Korea society with loan sharking, rising to upper class in new early modern era instead of traditional nobleman. Park Hyung-geol could be said romantic guy, second, have chased romatic love consist of three elements(love-sex-marriage). But he troubled his love affairs to his family members frustrated his will because of a bastard son. It is the model of situations, Kim Nan-cheon intended to describe, that Homo Economicus became an object of envy among people in early modern society as well as the choice has been hard in conflicting between family and lover, concretizing anachronism through history of family.

  • Feminist artists are special in Chinese modern art. Sticking to their own artistic ideas, they constantly emphasize women's psychological characteristics and aesthetic values in their works under the background of modern society. Since feminism was introduced into China from western arts in the 1970s, it has greatly inspired Chinese female artists. This study used comparative analysis and correlation analysis to establish the connection between the works of local Chinese female artists and modern women's wear design, this connection is the common language form of Chinese female artists and modern fashion designers when expressing female psychology and aesthetics. This is a way for Chinese female artists to seek dialogue with Western and global female art, and the development characteristics of the localization of feminism in Chinese art and design. The significance of the research is to improve the international artistic atmosphere of Chinese feminist art and instill a new understanding of Chinese feminist art in the world.

  • The vocabulary of modern grand hotels' interior designs reflects western design patterns, showing its nostalgia for modern architecture. And it also contains the trace of past designs implanted by others then, expressing the hardships of Korean history. Like this, the past architectural style distorted under the Japanese imperialistic rule has continued to exist until now without any significant changes, because there has been little effort to figure out the history of modern interior designs. And also there has been the lack of data and aesthetic descriptions about the modern interior designs that contain the historical nature of society. Therefore, this study will review the interior design of modern buildings, which trace back to the fawning of the Korean Interior Design. And it aims to understand the hotel interior's expressive characteristics and historical meanings by paying a particular attention to its lost parts. And it also alms to have a significant meaning in taking the first step toward a clue of the history of Korean modern interiors by systematically putting in order the ever-disappearing materials of modern hotel interiors.

  • The purpose of this study is to analyze the aesthetic characteristics of 'movement' expression in modern fashion(1910-2004) based on a study of modern fine arts which adopted 'movement' element in their work. In this study the meaning of movement was defined as motion, changing position and transformation. Literature survey through books and research papers and demonstrative study with fashion collection photos were undertaken. The results wert as follows ; 1) Kinetic art, optical an, light kinetic art and technology art such as video and computer art have adopted 'movement' element in their work. 2) The plasticities of 'movement' fine arts were identified as mutual penetration, increase of visibility, use of non-traditional materials and dynamism. The internal meanings were identified as expansion of aesthetic experience and the concept of fine art, optimistic attitude on technology, spectator participation and integration of art and life. 3) The 'movement' expression in modern fashion was distinctively found in 1910s-20s(avant-garde fashion), 1960s (kinetic and optical art fashion) and mid 1990s to 2004 (techno-cyber fashion). 4) The plasticities of the 'movement' expression in modern fashion were identified as non-definition, use of non-traditional materials, dynamism. The internal meanings were identified as expansion of aesthetic experience and the concept of dress, optimistic attitude on technology, playfulness through participation. In conclusion, the expression of 'movement' in modern fashion has optimistic viewpoint on the development of modern society and is one of the interesting design points which will be pursued in the fellowing years.
