The purpose of this study was to investigate the relationship between Chanel design and her Costume jewelry in 1920's-1930's through documentary studies. According to the study the result was as follows: 1. Chanel's esthetic in the field of Fashion Design bore the double stamp of "elegance" and 'simplicity' 2. Chanel changed the concept of costume jewelry. Chanel's great innovation was that she let 'fake' jewels always keep the intrinsic value of 'real' ones. 3. The simplicity of her perfectly tailored suit was Paradoxically overwhelmed by a fan-tastic array of jewels. The relationhship be-tween Chanel design and her costume jewelry was not able to be seperated. Chanel was a fashion leader fifty years ago and the name "Chanel" will be at the forefornt of fashon fifty years from now. The image of quality will always remain the same in the futures.

This paper aims to give a quick view on denoising without comprehensive details. Denoising can be understood as removing unwanted parts in signals and images. Noise incorporates intrinsic random fluctuations in the data. Since noise is ubiquitous, denoising methods and models are diverse. Starting from what noise means, we briefly discuss a denoising model as maximum a posteriori estimation and relate it with a variational form or energy model. After that we present a few major branches in image and signal processing; filtering, shrinkage or thresholding, regularization and data adapted methods, although it may not be a general way of classifying denoising methods.

The repeatability of fabric drape was studied. Two methods for draping were used and the relation between node distributions was investigated using statistical analysis. With this, the relationship between node distribution and fabric mechanical properties was studied. The repeated measurements showed that there was no evidence that fabric has intrinsic node number and the mechanical properties influence on the number of nodes.

We present a GUI-based interactive Python program, VIMAP, which generates radio spectral index maps of active galactic nuclei (AGN) from Very Long Baseline Interferometry (VLBI) maps obtained at different frequencies. VIMAP is a handy tool for the spectral analysis of synchrotron emission from AGN jets, specifically of spectral index distributions, turn-over frequencies, and core-shifts. In general, the required accurate image alignment is difficult to achieve because of a loss of absolute spatial coordinate information during VLBI data reduction (self-calibration) and/or intrinsic variations of source structure as function of frequency. These issues are overcome by VIMAP which in turn is based on the two-dimensional cross-correlation algorithm of Croke & Gabuzda (2008). In this paper, we briefly review the problem of aligning VLBI AGN maps, describe the workflow of VIMAP, and present an analysis of archival VLBI maps of the active nucleus 3C 120.

Among the diverse apartment brand TV Ads, KCC Switzen uses a unique advertising strategy. Unlike their competitors, KCC Switzen uses a strategy without fancy rhetoric such as luxury, premium or high-tech to enhance the value of their housing. In order to define the value of contemporary housing this paper analyses the socio-cultural messaging of KCC Switzen's television advertisements using Qualitative content analysis and Floch's Semiotic Square of Consumption Values method. As a result of this analysis, KCC Switzen's advertisements are shown to contain both intrinsic values of housing and cultural humanism by asking ablout the daily lives of real families and their relationships with neighbors. This directly contrasts with the standard advertisements that focus on the investment value of residential housing. The unique KCC Switzen advertising strategies are expected to change the paradigm of residential housing.

Digital media technology is gradually developing with the development of convergence quaternary industrial technology and mobile devices. The combination of deep learning and augmented reality can provide more convenient and lively services through the interaction of 3D virtual images with the real world. We combine deep learning-based pose prediction with augmented reality technology. We predict the eight vertices of the bounding box of the object in the image. Using the predicted eight vertices(x,y), eight vertices(x,y,z) of 3D mesh, and the intrinsic parameter of the smartphone camera, we compute the external parameters of the camera through the PnP algorithm. We calculate the distance to the object and the degree of rotation of the object using the external parameter and apply to AR content. Our method provides services in a web environment, making it highly accessible to users and easy to maintain the system. As we provide augmented reality services using consumers' smartphone cameras, we can apply them to various business fields.

The sensor system to measure the distance precisely from the center of the sensor system to the obstacle is needed to recognize the surrounding environments, and the sensor system is to be calibrated thoroughly to get the range information exactly. This study covers the calibration of the active range sensor which consists of camera and laser slit emitting device, and provides the equations to get the 3D range data. This can be possible by obtaining the extrinsic parameters of laser slit emitting device through image processing the slits measured during the constant distance intervals and the intrinsic parameters from the calibration of camera. The 3D range data equation derived from the simple geometric assumptions is proved to be applicable to the general cases using the calibration parameters. Also the exact 3D range data were obtained to the object from the real experiment.

Our study explores the connection between the Pythagorean theorem and the Fixed-point theorem in metric spaces. Both of which center around the concepts of distance transformations and point relationships. The Pythagorean theorem deals with right triangles in Euclidean space, emphasizing distances between points. In contrast, fixed-point theorems pertain to the points that remain unchanged under specific transformations thereby preserving distances. The article delves into the intrinsic correlation between these concepts and presents a novel study in Euclidean metric spaces, examining the relationship between contraction mapping and Pythagorean Right Triangles. Practical applications are also discussed particularly in the context of image compression. Here, the integration of the Pythagorean right triangle paradigm with contraction mappings results in efficient data representation and the preservation of visual data relation-ships. This illustrates the practical utility of seemingly abstract theories in addressing real-world challenges.

In fashion, there are various cultural aspects that exist in complexity, where according to the era, even fashion items newly develop and prevail into various designs in the organic function with reality of related cultural phenomenon and aesthetic aim. Among the fashion items, the shoe is historically considered as the shield from lust and also the provision of praise against the most emotional incitement. Mankind has started wearing shoes out of the functional purpose of protection since the ancient Egyptian times. Thereafter humankind has been creating shoes artistically in respect to shape, color, and quality of material, etc, as an expression of aesthetical awareness and introspective desire for beauty. As modern fashion increasingly regards the total fashion image much more important than each items consisting the whole outfit, the role of shoe became essential more than ever. Contrary to its relative importance, little academic attention was given to this area yet, while prestigious museums and galleries in Europe and the USA have held exhibitions of shoes in view of both historical and artistic aspects. This study aims to make a historical inquiry of western shoes. through which their aesthetic values can be drawn. Literature on this subject including aesthetics, history of costume and arts were referred. Fashion magazines and catalogues were investigated for additional information. The process and results of this study are meant to be a suggestion not only to further studies but also to artistic and creative shoe design. Originated for the functional purpose, shoes have evolved in various shapes with different meanings attached to it. When the technological development made the satisfaction for functional needs possible, the intrinsic attribute, the aesthetic value was pursued. The historical contemplations of shoes from Egyptian times to the 1990's led to the results that the intrinsic aesthetic value of shoes can be summarized as follows: 1) protection and extension of body, 2) need for decoration, 3) erotic expression, 4) symbol of dignity and class, 5) fashion.
