이 글은 민요 기능과 전승 현장이 현대화에 밀려 변질되거나 사라지는 상황에서 민요 보존과 계승, 연구를 위한 새로운 방법을 모색하고자 하는 데서 출발한다. 그리고 민요에 대한 새로운 조명과 함께 새로운 민요 연구 방법론 개발을 위해 '융합'을 주목하였다. 융합은 둘 이상의 결합과정에서 구조적인 변화가 일어나는 것을 말하며 해체와 분화를 지향하는 가운데 중심과 주변의 인식이 없어지는 등, 경계허물기 작업과 관련한다. 그리고 융합적 연구방법을 실행하기 위해서는 통섭(通涉)적 연구시각을 가질 필요가 있다. 학제적 연구는 학문간 차이를 인정하는 데서부터 시작되며, 그 차이가 유의미한 가치를 가지는 한 해체와 분화를 반복한다. 즉, 융합은 해체를 통해 새롭게 태어난다. 이런 논리에 따르자면 융합적 민요연구를 위해서는 민요의 구조와 구성인자를 새롭게 살피고 전체를 구성하는 부분과 원리를 이해할 필요가 있다. 그리고 그 부분을 다른 그 무엇과 결합시키거나 통섭적으로 견주어 새롭게 해석하는 노력이 필요하다. 이 글에서는 그러한 융합합의 민요 연구 사례로 문화학, 생명사회학, 공감이론으로서의 민요연구방법을 살펴보았다. 다양한 시각으로 민요를 돌아볼 때 민요는 새롭게 해석될 수 있을 것이다.

Super resolution technique aims to convert a low-resolution image with coarse details to a corresponding high-resolution image with refined details. In the past decades, the performance is greatly improved due to progress of deep learning models. However, universal solution for various objects is a still challenging issue. We observe that learning super resolution with a general dataset has poor performance on faces. In this paper, we propose a super resolution fusion scheme that works well for both general- and face datasets to achieve more universal solution. In addition, object-specific feature extractor is employed for better reconstruction performance. In our experiments, we compare our fusion image and super-resolved images from one- of the state-of-the-art deep learning models trained with DIV2K and FFHQ datasets. Quantitative and qualitative evaluates show that our fusion scheme successfully works well for both datasets. We expect our fusion scheme to be effective on other objects with poor performance and this will lead to universal solutions.

The role of electromagnetic (EM) waves in magnetic fusion plasma-ranging from radio frequency (RF) to microwaves-has been extremely important, and understanding of EM wave propagation and related technology in this field has significantly advanced magnetic fusion plasma research. Auxiliary heating and current drive systems, aided by various forms of high-power RF and microwave sources, have contributed to achieving the required steady-state operation of plasmas with high temperatures (i.e., up to approximately 10 keV; 1 eV=10000 K) that are suitable for future fusion reactors. Here, various resonance values and cut-off characteristics of wave propagation in plasmas with a nonuniform magnetic field are used to optimize the efficiency of heating and current drive systems. In diagnostic applications, passive emissions and active sources in this frequency range are used to measure plasma parameters and dynamics; in particular, measurements of electron cyclotron emissions (ECEs) provide profile information regarding electron temperature. Recent developments in state-of-the-art 2D microwave imaging systems that measure fluctuations in electron temperature and density are largely based on ECE. The scattering process, phase delays, reflection/diffraction, and the polarization of actively launched EM waves provide us with the physics of magnetohydrodynamic instabilities and transport physics.

The purpose of multimodal medical image fusion (MMIF) is to integrate images of different modes with different details into a result image with rich information, which is convenient for doctors to accurately diagnose and treat the diseased tissues of patients. Encouraged by this purpose, this paper proposes a novel method based on a two-scale decomposer and detail preservation model. The first step is to use the two-scale decomposer to decompose the source image into the energy layers and structure layers, which have the characteristic of detail preservation. And then, structure tensor operator and max-abs are combined to fuse the structure layers. The detail preservation model is proposed for the fusion of the energy layers, which greatly improves the image performance. The fused image is achieved by summing up the two fused sub-images obtained by the above fusion rules. Experiments demonstrate that the proposed method has superior performance compared with the state-of-the-art fusion methods.

The purpose of infrared and visible image fusion is to integrate images of different modes with different details into a result image with rich information, which is convenient for high-level computer vision task. Considering many deep networks only work in a single scale, this paper proposes a novel image fusion based on three-scale dense network to preserve the content and key target features from the input images in the fused image. It comprises an encoder, a three-scale block, a fused strategy and a decoder, which can capture incredibly rich background details and prominent target details. The encoder is used to extract three-scale dense features from the source images for the initial image fusion. Then, a fusion strategy called l₁-norm to fuse features of different scales. Finally, the fused image is reconstructed by decoding network. Compared with the existing methods, the proposed method can achieve state-of-the-art fusion performance in subjective observation.

지금까지의 정보검색 연구에서 데이터 융합 기법을 이용한 문서 검색은 하나의 알고리즘에 의한 검색에 비하여 많은 경우에 효율성이 높은 결과를 얻을 수 있었다. 하지만 이미지 검색에서 상이한 알고리즘을 이용한 다수의 검색 결과를 합쳐 하나의 검색결과를 얻는 데이터 융합 기법의 사용은 많지 않았다. 이 연구에서는 소벨 연산자를 이용한 윤곽선 검출과 자기조직화 지도 알고리즘에 의한 두 검색 결과를 융합하여 각각의 알고리즘에 의한 검색결과 보다 높은 효율성을 보여주는 방법을 제시하였다. 이 연구에서는 상용 클립아트 이미지를 이용하여 사람의 주관적인 적합성 판단을 배제한 검색 실험 데이터를 만들어 사용하였다.

Contemporary fashion is experiencing a rise in design that combines heterogeneous things, or goes beyond the roles, boundaries, and meanings of existing things. This can be described as a 'heterogeneous fusion' that is different in character from the mixed use of heterogeneous materials, borrowed designs, and exaggeration of the silhouette that have been practices in fashion design, or the non-structure, deconstruction, and recombination that have existed since the age when post-structuralism was a central philosophy. This 'fusion' causes a 'confusion' of the generally accepted mental principle of 'one sense reacting to one stimulus', and breaks the boundary between the various senses, causing confusion in the senses of the individual, and leading him or her to experience unfamiliar feelings. In this process, all information received from external sources is not perceived as it is seen, but rather is perceived through a fusion of the individual's motivations, the environment in which it is perceived, the resulting change in emotion, and the individual's past memories. The combination of these heterogeneous elements visually accepted, or such a non-territorial combination acts as a 'fusion of senses' in the individual's perception, which causes confusion in the homeostasis of perception, and a change in emotion, and serves as a factor that causes the information to be stored in the memory for a long time. In parallel with deconstruction or non-structure, the 'heterogeneous fusion' found in modern fashion is taking root as a representative creative trend, and is represented in various forms such as the mixed use of subjects and materials, non-territorial borrowing, fusion with animal forms, fusion with non-physical geometry, and fusion with heterogeneous hair decoration.

Fusing the scores of multibiometrics is a very promising approach to improve the overall system's accuracy and the verification performance. In recent years, there are several approaches towards studying score level fusion of several biometric systems. However, most of them does not consider the genuine and imposter score distributions and result in a higher equal error rate usually. In this paper, a novel score level fusion approach of different biometric systems (dual iris, thermal and visible face traits) based on $Acz{\acute{e}}l$-Alsina triangular norm is proposed. It achieves higher identification performance as well as acquires a closer genuine distance and larger imposter distance. The experimental tests are conducted on a virtual multibiometrics database, which merges the challenging CASIA-Iris-Thousand database with noisy samples and the NVIE face database with visible and thermal face images. The rigorous results suggest that significant performance improvement can be achieved after the implementation of multibiometrics. The comparative experiments also ascertain that the proposed fusion approach outperforms the state-of-art verification performance.
