In this study, the effects of psychosocial stress (box color and precision demand) on muscle activity were evaluated in laboratory setting. Eight subjects performed sagittally symmetric lifting tasks. Box color (yellow, black), precision demand (yes, no), and box weight (5%MVC, 10%MVC, 15 %MVC) were varied and surface EMG signals from seven muscles(medial deltoid right, biceps brachii right, lateral triceps right, latissimus dorsi right, erector spinae right, external oblique right, internal oblique right) were recorded. EMG signals were band-pass filtered($10{\sim}400\;Hz$), rectified, RMS smoothed and normalized (NEMG). Analysis of variance tests were conducted on the total NEMG (TNEMG: the sum of the seven muscles' NEMGs) and on the individual muscle's NEMGs. Box color had no effect on the TNEMG and on the seven muscles activities(p>0.05). When precision demand was required at the end point of lifts, the mean NEMG showed higher values than no precision demand conditions: TNEMG (14% increase) and medial deltoid(40% increase), biceps brachii(10% increase), lateral triceps(26% increase), latissimus dorsi(25% increase) muscles. Those increases showed more conspicuous as the box weight increased in the muscles of medial deltoid, lateral triceps, and latissimus dorsi.

The applicability of the ultrafiltration process for color removal from dye-containing water has been examined in this study. The optimization of major process variables, such as dye concentration, chitosan concentration and transmembrane pressure on permeate flux and color removal efficiency was investigated. To find the most appropriate results for the experiment, the Box-Wilson experimental design method was employed. The results were correlated by a response function and the coefficients were determined by regression analysis. Permeate flux variation and color removal efficiency determined from the response functions were in good agreement with the experimental results. The optimum conditions of chitosan concentration, dye concentration and pressure were 50 mg/l, 50 mg/l and 3 bars, respectively for the highest permeate flux. On the other hand, optimum conditions for color removal efficiency were determined as 50 mg/l of dye concentration, 50 mg/l of chitosan concentration and 1 bar of pressure.

This paper is a study on the expression of Clothing and Textiles recorded in $\boxDr$Eigamonokatary$\boxUl$ focus on Color and Dying. $\boxDr$Eigamonokatary$\boxUl$is a novel described the life style of Royal Court from 883 till 1107. The discoveries of this paper were as follows. 1. The materials of colors and dyeing which are described in this book reflect the features of the age well. We can assume that the point of its chic might rest on colors and dyeing than design or pattern. 2. Sine they enjoyed wearing lots of clothes which are in the same design but in different colors with the underwear. When color coordinate was fashioned we call them "Kasanenoirome". This type of dressing was in vogue in the age of Heian when there were several devices of showing chic in dressing. 3. The color of clothes at that time might represent one's official position the black the highest class following the purple the red and the blue or green. The black color was made from the purple or blue. The Japanese Emperor would wear reddish yellow or blue clothes according to the nature of his office work. 4. Some of Japanese fashion might be influenced by Korean styles in the respects of coordinating colors and adjusting Buddhist fashion etc. It is required that the turther studies of comparing Korean fashion styles with Japanese ones should be deepened. deepened.

This document outlines a new color image encryption technology development. After splitting the original image into 240-bit blocks and modifying the first block by an initialization vector, an improved Feistel circuit is applied, sponsored by a genetic crossover operator and then strong chaining between the encrypted block and the next clear block is attached to set up the confusion-diffusion and heighten the avalanche effect, which protects the system from any known attack. Simulations carried out on a large database of color images of different sizes and formats prove the robustness of such a system.

In this paper, we propose a traffic light detection and recognition (TLDR) algorithm in the daytime. The proposed algorithm utilizes the color and shape information for the TLDR. At first, a traffic light is detected and recognized based on its shape information. Then, the color range of the detected traffic light is investigated in HSV color space. The input data of the proposed TLDR algorithm is the color image captured using the black box camera during driving. Our simulations demonstrate that the proposed algorithm can achieve a high detection and recognition performance for the images including traffic lights.

In this paper, a novel text binarization is presented that can deal with some complex conditions, such as shadows, non-uniform illumination due to highlight or object projection, and messy backgrounds. To locate the target text region, a focus line is assumed to pass through a text region. Next, connected component analysis and stroke width estimation based on location information of the focus line is used to locate the bounding box of the text region, and each box of connected components. A series of classifications are applied to identify whether each CC(Connected component) is text or non-text. Also, a modified K-means clustering method based on an HCL color space is applied to reduce the color dimension. A text binarization procedure based on location of text component and seed color pixel is then used to generate the final result.

A blind box is a kind of sales method in that you can only get the product information by opening the package. In 2019, blind box products began to grow rapidly in the Chinese market, and gradually formed a special "blind box economy". The particularity of blind box products is that driven by consumers' curiosity, consumers' purchasing behavior can be directly induced by the visual and tactile perception of commodity packaging. Therefore, it is necessary to explore the psychological needs of consumers and master the blind box packaging design elements under the influence of consumer psychology. This paper takes figurine blind box packaging elements as the research scope and Chinese blind box consumers as the research object. Through market research and literature study, We are designed to conduct a questionnaire survey and SPSS empirical study to find out the differences in the preferences of different consumer temperament types for blind box packaging, taking the characteristics of blind box products and consumer psychology as the relevant theoretical background. The research results show that among the blind box consumers, choleric type consumers predominate, the color of the blind box packaging presents red, orange, and yellow preference, and the material presents metal, and plastic preference. The shape of the blind box shows a preference for special shape.

The secure access the lighting, Heating, ventilation, and air conditioning (HVAC), fire safety, and security control boxes of building facilities is the primary objective of future smart buildings. This paper proposes an authorized user access to the electrical, lighting, fire safety, and security control boxes in the smart building, by using color grid coded optical camera communication (OCC) with face recognition Technologies. The existing CCTV subsystem can be used as the face recognition security subsystem for the proposed approach. At the same time a smart device attached camera can used as an OCC receiver of color grid code for user access authentication data sent by the control boxes to proceed authorization. This proposed approach allows increasing an authorization control reliability and highly secured authentication on accessing building facility infrastructure. The result of color grid code sequence received by the unauthorized person and his face identification allows getting good results in security and gaining effectiveness of accessing building facility infrastructure. The proposed concept uses the encoded user access authentication information through control box monitor and the smart device application which detect and decode the color grid coded informations combinations and then send user through the smart building network to building management system for authentication verification in combination with the facial features that gives a high protection level. The proposed concept is implemented on testbed model and experiment results verified for the secured user authentication in real-time.
