최근, 다양한 정보의 수집 및 처리가 필요한 스마트 홈, 의료, 교통, 제조 등 여러 산업 분야에서 IoT(Internet of Things)가 많이 활용되고 있다. 특히 스마트 홈 환경에서 IoT 장치로 수집되는 정보는 민감한 개인 정보를 포함할 수 있기 때문에 특정 그룹이나 개인만이 해당 정보에 접근할 수 있도록 관리할 필요가 있다. 또한, IoT 환경에서 Blockchain 기반으로 데이터의 신뢰성을 확보하는 분산 저장소의 경우, 지연 시간의 증가 문제가 발생될 수 있기 때문에 실시간 데이터 수집에 대한 처리 속도를 향상할 방안이 필요하다. 본 논문에서는 사용자와 IoT 장치 간 생성한 그룹 ID 로 해당 그룹에 대한 접근 권한을 관리하고, Hyperledger Fabric 과 별도의 데이터베이스 운용으로 실시간성, 신뢰성을 향상할 수 있는 Hyperledger Fabric 기반 스마트 홈 Architecture 를 제안한다. 이 Architecture는 IoT 장치가 사용되는 다양한 환경에서 보안성, 실시간성, 신뢰성을 향상할 수 있을 것이다.

There are Two new models developed for objective evaluation of fabric color patterns by applying a multiple regression analysis and an adaptive foray-rule-based system. The physical features of fabric color patterns are extracted through digital image processing and the emotional features are collected based on the psychological experiments of Soen[3, 4]. The principle physical features are hue, saturation, intensity and the texture of color patterns. The emotional features arc represented thirteen pairs of adverse adjectives. The multiple regression analyses and the adaptive fuzzy system are used as a tool to analyze the relations between physical and emotional features. As a result, both of the proposed models show competent performance for the approximation and the similar linguistic interpretation to the Soen's psychological experiments.

The purpose of this study is to analyze how the men＇s fashion with the representation of Feminization which has appeared on our specialized fashion magazine from 1990 though 2003. Firstly, the factor which exposed the representation of Feminization in men＇s fashion were the change of conventional sex role, the change of ideal beauty, the variety of information, the pursuit of personality and the polycentrism of thought. Secondly, the formative characteristics of Feminization in men＇s fashion represented fitted silhouettes which distinctively show the body line, elastic fabric and see-through fabric of androgynous image, accessory and wave hair which expressed in gentle image. In colors, it represented vivid tone, pastel tone, red colors and yellow colors. Fitted silhouttes and elastic fabric has a effect of minimalism of the last 1990＇s fashion, and wave hair of gentle image has a effect of change of ideal beauty since 2000. Therefore, elements of representation of Feminization in men＇s fashion were silhoutte, fabric, color, accessory, hairstyle and the representation of feminity in men＇s fashion has referance to fashion.

As companies specialize, they use more modern applications, but they still rely on legacy systems and data access is limited by data silos. In this paper, we propose the Fabricator system, a design system for metadata based on Data Fabric that plays a key role in the data orchestration layer consisting of three layers: Sources Engine, Workload Builder, and Data Fabric Ingestion, thereby achieving meaningful integration of data and information. Provides useful insights to users through conversion. This allows businesses to efficiently access and utilize data, overcoming the limitations of legacy systems.

In this research, a new quantitative fabric drape evaluation system has been developed using image processing technology. The purpose of this research is to get the more detailed information of fabric drapability quantitatively from digital images captured with a digital camera generally commercialized. The shape parameters of a 3-dimensional geometric drape model were defined as the number of nodes, frequency and amplitude. Also, various statistical information of drape shapes can be obtained using image processing technology and frequency analysis as well as traditional drape coefficients. Hardware system to capture drape images is simply composed of three parts including a digital USB (Universal Serial Bus) camera, a frame cover and a stand for camera to attach to traditional drape tester. The evaluation software coded with the MS Visual C++ is operated under the MS windows 9x above.

A blooming area of processor design is represented by scalable computing fabric. As the structure of the processors developed using seal-able computing fabric evolved from simple programmable units to processors supporting change of flow instructions and function calls, an increasing interest is in developing the compiling technology that will allow us to harness not only the full power of their hardware but also to target multiple architectures. In this paper we present the front-end of a generic compiler, able to accept a various source languages and transform them in a common intermediate representation.

Precedent researches on lyocell are mostly on lyocell structure, characteristics, physical properties by finishing and dyeability, and the like; there are little cases of researches on interlining for lyocell clothes production. To serve as a base information helpful to select fusible interlining and improve the efficiency of sewing process considering the characteristics of lyocell, this study performed t-est, F-test toward to the difference in the appearance-related properties and the mechanical properties of lyocell-interlining bonded fabric in accordance with the characteristics of fusible interlining and lyocell face fabric. This study reached following conclusions. Drapability and Crease recovery of lyocell-interlining bonded fabric are influenced by the structure of fusible interlining; stiffness of lyocell-interlining bonded fabric, by the structure of fusible interlining and the yam number of lyocell face fabric. WT is influenced by the mixture rate and yam number of lyocell face fabric. RT is influenced by the yam number of lyocell face fabric; G, 2HG, 2HG5, by the structure(woven and non-woven) of fusible interlining; B, HB, by the weight, structure(woven and non-woven) of fusible interlining, and yam number of lyocell face fabric; WC, by the weight, structure of fusible interlining; RC, by the structure of fusible interlining; thickness, by the weight of fusible interlining and the yarn number of lyocell face fabric; weight, by mixture rate and yam number of lyocell face fabric.

The algorithm developed in this paper allows us to generate or synthesize a large amount of data sets using only a small amount of signal features obtained from the original data set. Because the simulated density profiles of yarns retain the original features without a significant loss of information on the location of imperfections, the resulting fabric images are likely to resemble the original images. The data expansion system developed could generate a large area of fabric images by combining the Monte Carlo simulation and the wavelet sub-band exchange algorithm developed. The system has proven effective for simulating realistic fabric images by retaining the location of imperfections such as neps, thin and thick places.

Re water resistance of shell fabrics intended for we in outdoor apparel was measured using three different standard test methods, ASTM D 751, hydrostatic resistance, procedure A(Mullen test -- with and without a fabric support) and Procedure B (Hydrostatic head test). A database of information on their water resistance performance was created. The data collected with different methods were correlated and the advantages and disadvantages of each method were compared. The Mullen test with a support appears to give higher and more favorable water resistance values on shell fabrics preventing fabric rupture during the test. The hydrostatic head test gave lower hydrostatic pressure values than those measured on the two Mullen tests. The Mullen test is recommended for testing the water resistance of fabrics that high a relatively high water resistance because the Mullen tester applies a wide range of pressure. The hydrostatic head test is recommended for testing the fabrics that have relatively low water resistance. The area of the fabric sample that is in contact with the water is smaller in the Mullen test, so higher pressure levels can be reached and more samples should probably be tested to get a representative value for each fabric types. Furthermore, the hydrostatic head test was deemed more repeatable than the Mullen tests in his study.
