테크노팝이라는 용어가 40년전 처음으로 사용된 이후 테크노 음악은 기술의 진보와 함께 많은 발전을 거듭했다. 그러나 테크노 음악을 음악사적 관점에서 고찰한 연구는 적은 편이며, 특히 그 태생적 특성과 관련하여 산업 기술적 측면의 발달에 대해서 이해해 볼 필요가 있다. 이에 본 논문에서는 테크노가 본격 태동하던 시기의 디트로이트 테크노와 관련한 역사적 맥락을 살펴보고 특히 큰 성공을 거둔 유럽의 테크노 문화, 그리고 테크노 음악의 산업적 의의에 대해 살펴보고자 한다. 또한 테크노 음악의 발전과 관련한 제언을 제공하고자 한다.

많은 대중들은 가수 신해철에 대해 음악프로듀서, 싱어송라이터, 작곡가 등 다양한 음악적 활동을 했던 뮤지션으로 알고 있다. 그러나 그는 그 외에도 각종 대중매체에 다 방면으로 활발한 활동을 했던 전 방위적인 엔터테이너이기도 하다. 그의 음악적인 성향은 매우 진보적이며, 다양한 시도와 실험적인 퓨전 스타일의 음악을 지향한다. 그의 앨범 중 '모노크롬'은 독특한 테크노 음악과 전통음악을 접목한 결과물로 새로운 사운드를 향한 음악적인 가치와 의미에서 한국대중음악의 수준을 한 차원 끌어 올렸다는 평가를 받고 있다. 본 앨범에서 국악의 비중은 매우 높다. 꽹과리, 장구, 징 등 사물놀이 전통악기뿐만 아니라, 대금, 태평소, 품바, 타령 등을 사용, 기존 국악과의 협업을 통해 보다 진보된 확장성 있는 크로스오버 음악을 보여주고 있다. 현재 'K-Pop'이 세계적인 음악으로 계속 사랑받기 위해서는 음악적인 확장성을 기반을 둔 새로운 시도가 무엇보다 필요하다고 본다. 그렇기 때문에 모노크롬 앨범에서처럼 국악을 음악적 기재(器財)로 사용한다면, 차별성을 둔 우리만의 음악을 만들 수 있으며, 그로 인해 세계적으로 높은 'K-Pop'의 관심도 지속될 수 있을 것이라고 생각한다.

In the present study, we aim to use nanotechnology sensors/actuators to capture pressure and frequency of voice singers and to send signals for improving breathing pressure. In this regard, a circular composite structure having 3 different layers are used. The core layer is nano-composite material reinforced with graphene nanoplatelets. The face sheets are piezo electric materials connected to electrical circuit capable of measuring and applying voltage to the piezoelectric layers. This sensors have extremely smaller size than conventional sensors attached to the neck of singer and, hence, minimizes the influences on the output voice of the singer. A brief theoretical framework are presented for nonlocal strain gradient theory and geometry of the sensor is described in detail. The controlling procedure along with experimental results on 20 amateur and professional singer participants are also presented. The results of the study indicate that the participants could gain benefit from the device for improving their ability in phonation and keeping their frequency at a constant level although they have difficulty in the beginning of the experiment getting used to the device.

Since the beginning of the 90's, Fashion shows appear to be a type of performance form of art combining with other areas to visually entertain the viewers. This can be explained by the modern tendency to escape from society which requires formality and complicated lifestyles. Fashion shows take place in a scene Influenced by the idea of post-modernism which redefines the definition of space. A church, old factory, unoccupied ground, subway stations, or even place like a waste disposal are used as a setting. The stage set is no longer the T shape run way and the procinium arch has disappeared. The gap between audience and stage has diminished and theatrical element is added to the fashion performance by using viewers living and working environments as setting of the show. The human relation with machine based on the cutting edge technology such as the stage automation, robots and mist making sprinkler system introduces new elements with spontaneity and detailed planning in the stage performance. Music also plays an Important role in attracting viewers. The sound track covers house music to techno music. Instead of music being abstract, folks orchestral music, choirs, piano. even live concert performed by pop artist provide the liveliness of the fashion show. And the catwalk itself is a performance. Model needs to be well trained as the capable talent who can handle sensitive gestures, facial expressions, dancing and choreography. The improvisatorial interaction between audience and model lead to audience participation. Models now range from pop star, ordinary people, handicapped people, to elderly and so on. John Galliano introduced the theatrical factors for the fashion show and Alexander Mcqueen approached the fashion show as the visual art of communication. Hussein Chalayan utilized high technology skewing futurism as if in a magic show. Today the Fashion show tends to be a total performance which includes audience participation, impromptu, and that break the limitation that fashion shows previously had. This will lead the fashion industry in opening new horizon of its own.

Due to the degradation of beamforming properties at angles close to $0^{\circ}$ to $180^{\circ}$, linear array does not have a complete $180^{\circ}$ inspection range but a smaller one. This paper develops a improved sensor array with two additional sensors above and below the linear sensor array, and presents time difference and two dimensional multiple signal classification (2D-MUSIC) based impact localization for omni-directional localization on composite structures. Firstly, the arrival times of impact signal observed by two additional sensors are determined using the wavelet transform and compared, and the direction range of impact source can be decided in general, $0^{\circ}$ to $180^{\circ}$ or $180^{\circ}$ to $360^{\circ}$. And then, 2D-MUSIC based spatial spectrum formula using uniform linear array is applied for locate accurate position of impact source. When the arrival time of impact signal observed by two additional sensors is equal, the direction of impact source can be located at $0^{\circ}$ or $180^{\circ}$ by comparing the first and last sensor of linear array. And then the distance is estimated by time difference algorithm. To verify the proposed approach, it is applied to a quasi-isotropic epoxy laminate plate and a stiffened composite panel. The results are in good agreement with the actual impact occurring position.

Real-time near and far-field monitoring of concrete structural components gives enough information on the time and condition at which damage occurs, thereby facilitating damage detection while in the same time evaluate the cause of the damage. This paper experimentally investigates an integrated monitoring technique for near and far-field damage detection in concrete structures based on simultaneous use of electromechanical admittance technique in combination with guided wave propagation. The proposed sensing system does not measure the electromechanical admittance itself but detect time variations in output voltages of the response signal obtained across the electrodes of piezoelectric transducers bonded on surfaces of concrete structures. The damage identification is based on the spectral estimation MUSIC algorithm. Experimental results show the efficiency and performance of the proposed measuring technique.

In this article, a harmony search algorithm is presented for optimum design of steel frame structures. Harmony search is a meta-heuristic search method which has been developed recently. It is based on the analogy between the performance process of natural music and searching for solutions of optimization problems. The design algorithms obtain minimum weight frames by selecting suitable sections from a standard set of steel sections such as American Institute of Steel Construction (AISC) wide-flange (W) shapes. Stress constraints of AISC Load and Resistance Factor Design (LRFD) and AISC Allowable Stress Design (ASD) specifications, maximum (lateral displacement) and interstorey drift constraints, and also size constraint for columns were imposed on frames. The results of harmony search algorithm were compared to those of the other optimization algorithms such as genetic algorithm, optimality criterion and simulated annealing for two planar and two space frame structures taken from the literature. The comparisons showed that the harmony search algorithm yielded lighter designs for the design examples presented.
