The purpose of this study is to investigate the types and functions of brand labels on clothing. We surveyed the materials and manufacturing methods for brand labels by visiting the label stores and label manufacturers. 200 pieces of children's wear were surveyed. The label attributes that were studied were: the number of labels, the location of the labels, the attachment system for the labels, the color of the labels, the materials used to make the labels, manufacturing methods, and the size of the labels. From this investigation a brand label was classified into a main label and a point label. The main results were: 1. Materials such as fabrics, nonwovens, leather, suede, rubber, PVC, silicone, and metals are used for brand labels. The manufacturing methods for brand labels are weaving, printing, high frequency, heating, and molding. 2. More than 54% of clothes have more than two brand labels attached. This percentage exceeds the attaching of only one brand label in rate. An inside brand label is located at a certain place. This inside label uses only fabric material reflecting inherent brand color and design. The outside brand label is located at several places with consideration of the clothes design. This label uses various materials, colors, and characters matching with the clothes. As for the size, an inside label is mainly medium in size, whereas an outside label is small. 3. A brand label is classified into a main label (first label) and a point label (second label), which are defined as follows. A main label indicates the brand name and is located inside at a certain place using an inherent brand design and a fabric material. A point label is an additional label to express brand image and is located outside at various places for decoration using various characters and design and materials.

The local environmental effects on the triggering of active galactic nucleus(AGN) activity has been studied with many authors, but there still be controversy. We perform statistical analysis for nearby(0.01 < z < 0.05) volume limited(Mr < -19) samples with visual inspection based on Sloan Digital Sky Survey Data Release7. We inspect ~60,000 galaxy images visually to find peculiar objects which show not only ongoing merging features and tidal features, but also post merging features like ring or shell structures. We found that these peculiar features were shown at least 2 times more frequently among AGN host galaxies than non AGN galaxies, and this trend was still visible when galaxy properties such as color or stellar mass are fixed. Furthermore, L[OIII] and L(Ha) of peculiar galaxies are found to be more increased than those of normal galaxies. In order to ensure this results, we also checked it for a smaller subsample with ~2mag deeper monochromatic images provided from SDSS Stripe82 database, and found consistent results. At last, we perform the same work for pair(r_p<80kpc/h, delta_v<200km/s) systems. Because of some pair systems which do not interact gravitationally in actuality but fulfill the criteria for identification of pair system, the trends are found to be slightly weaker. We also found that line luminosities are increased consistently as projected distance between central and companion galaxy decreased, and as companion color gets bluer. Overall, the results of this study tell us that the local environment of galaxies affect the frequency as well as the strength of AGN activity. Local environmental effects, however, may not be the dominant triggering mechanism for AGN activity since the majority of peculiar galaxies are non AGN galaxies.

The purpose of this study was to observe the makeup behavior and cosmetics preference based on the segmented age group and fashion appearance interested group. The target consumers were women aged in their 20's. We distributed 443 questionnaires and conducted statistical analysis using SPSS program for the 400 reliable questionnaires. Statistical analyses included frequency, Chi-square test, t-test, ANOVA and cluster analysis(K-means). The results of this study were as follows: 1. There was a significant association between specific cosmetic items currently used and segmented age group. The age 24-29 had more basic makeup than color makeup, compared to the age 20-23 group. There was a statistical difference between the highly interested group and the lowly interested group in fashion and beauty. The group of highly interested in fashion and beauty considered trendy colors, while the group of lowly interested in fashion and beauty used their favorite color as an important factor in purchasing makeup products. 2. There was a significant difference in the preference of lip colors and textures, eye shadows textures, types of eye liner and types of foundation according to segmented age groups. 3. Those who sought 'sexy' images preferred red/wine/purple lipstick colors, and green/blue/violet eye shadow colors. They significantly preferred jell/liquid type eye liner and liquid type foundation. Those who sought 'pure' images preferred orange colors and glossy textures of lipsticks. Those who sought 'elegant' and 'intellectual' images preferred pearl type eye shadow.

This paper introduces a new algorithm to improve compression performance of 256 color images called palette-based or indexed images. The proposed scheme counts each frequency of index values after present index value and determines each rank for every index value by sorting them in descending order. Then, the scheme makes ranked index image instead of original indexed image using the way to replace index values with ranks. In the ranked index image's distribution produced as a result of this algorithm, the higher ranked index value, the more present same values. Therefore, data redundancy will be raised and more efficient performance of compression can be expected. Simulation results verify that because of higher compression ratio by up to 22.5, this newly designed algorithm shows a much better performance of compression in comparison with the arithmetic coding, intensity-based JPEG-LS and palette-based GIF.

This study was initiated to understand design and detail characteristics of coats that targeted new senior women by analyzing shape, color, fabric and detail. For the new senior, youthful appearance has more appeal than products that represent elder's style. Among, the coat can be effectively utilized as a trendy fashion item that targets seniors since it is more useful to hide figures than pants, blouses or jackets. The objectives of this research were to: First, examine design characteristics of new senior women's coat. Second, understand design characteristics of new senior women's coat. Third, analyze the relationship between the design of collars and details according to type of new senior women's coat. Photographs collected were categorized according to type of coat. Three types of coat (balmacaan, redingote and trench) were chosen to analyze with the highest frequency. The results of analyzing shape, length, color and fabric of the products made in domestic and foreign brands were similar; however, the collar and way of fastening showed significant results that required specific analysis since the design elements were related to maincoat characteristics in protecting against the cold. The depth of the V-zone can change without change of collar width and design changes in V-zone that influence the coat image that lead to changes in sleeve type and length (or fastening and closing position) method.

Recently, floating green algae (FGA) in open oceans and coastal waters have been reported over wide area, yet accurate detection of these using traditional ground based measurement and chemical analysis in the laboratory has been difficult or even impossible due to the lack of spatial resolution, coverage, and revisit frequency. In contrast, spectral reflectance measurement makes it possible to quickly assess the chlorophyll content in green algae. Our objectives are to investigate the spectral reflectance of the FGA observed in the Yellow Sea and to develop a new index to detect FGA from satellite imagery, namely floating green algae index (FGAI), which uses relatively simple reflectance ratio technique. The Moderate Resolution Imaging Spectroradiometer (MODIS) and Geostationary Ocean Color Imager (GOCI) satellite images at 500m spatial resolution were utilized to produce FGAI which is defined as the ratio between reflectance at 860nm and 660nm bands. Both FGAI results yielded reasonable green algae detection at the regional scale distribution. Especially houly GOCI observations can present more detaield information of FGAI than low-orbit satellite.

The purpose of this study is to investigate the consumers′ cognition and buying behavior on sports brand character. Since the character industries are booming, this study focused on the source and the expression method of sports brand characters that are already known to consumers. Subjects of this study were university students who were interested in sports brand characters, living in Seoul and Kyenggi-do. The questionnaire were developed based on the previous studies. Data were analysed by Frequency analysis, ANOVA, Duncan Test, and Spearman′s Rho. The results were as follows: 1. The most preferred source of sports brands character was "illustrated human figure"(i.e. a famous athlete like Michael Jordan). And the most favorite expression method of character was the combination of letter and symbol as the character of ASICS and NIKE. 2. The important design factors of sports brand character were the symbolism and aesthetics. The consumer recognized NIKE as the most well-designed character design. 3. Consumers′ preference of sports brand was found to be NIKE, REEBOK, ADIDAS, and FILA, in order. The reasons for preference were the design, the brand image, and the quality. On the other hand, the most frequently purchased brand was NIKE, FILA, and ADIDAS in order. Most of the purchase took place in the brand outlet store, and the consumers usually came with their friends for purchase of sports brand. The display of store was the consumers′ major source of information. 4. The preference group of sports brand character recognized more importantly color, design, brand, and especially fashionability than the non-preference group. And the most important criteria for brand selection were design, price, and comfort orderly. 5. Female consumers recognized more importantly color, design, brand, and others′ recommendations than male consumers. The aged consumers recognized importantly durability, comfort, and quality.

The purpose of this study was to compare the visual sensibility of red shirts in university students of two countries, Korea and China in order to suggest the color planning for shirts. Seven tonal red shirts' visual sensibility and preferences were evaluated by the students of Korea and from China in the sense of sight. Evaluated data were analyzed by using frequency analysis, average, factor analysis and t-test. The visual sensibility of red shirts was classified into three factors: sporty, romantic and classic. Those factors of visual sensibility showed a significant difference according to nationality and gender. The Chinese students had a more sporty feel to the strong tone, and a more classic feel to the dark tone than the Korean students. The deep tone red shirts was reputed to be more romantic by the Korean students, but the light tone and the pale tone were considered more romantic by the Chinese students. Meanwhile, the effects of nationality and gender on seven tone of preferences for red shirts was significantly differed.

LED-to-LED VLC is a technology that uses LEDs as both a transmitter and a receiver unlike the typical VLCs. In this paper, we experimentally demonstrate a micro LED-to-LED VLC using Micro LED. We tested all the possible VLC cases using red, yellow, green, blue, and white color LED as both a transmitter and a receiver, and measured rise time and SNR. Then we calculated channel capacity depending on the LED color sets. Our experimental results show that the best channel capacity is 125 kbps when the transmitter micro LED was blue and the receiver LED was green. We also measured BERs of VLCs using OFDM signal, and we showed a successful micro LED-to-LED VLC upto 250 kbps.

This paper proposes multiple access method for smart doorlock system using VLC(Visible Light Communication) with color grid modulation method. The proposed method is to connect multiple visible light signals using color grid modulation method in order to recognize and authenticate multiple users accessing doorlock. In order to enable visible light multiple access with existing infrastructure, the symbol energy interval of signal should be maximized. Thus, performance of system in VLC channel is measured by modulating symbols based on the proposed method. We confirm the actual channel test results of the modulated signal to implement doorlock system that recognizes the number of multiple access users.
