Clothing pressure is considered the essential factor affecting the comfort of clothing, so it is crucial that it is measured precisely. The purpose of this study is to construct a prototype using the Adafruit Flora as the Arduino system, which can be used as a wearable framework for easy, low-cost, and precise clothing pressure measurement. The study also aims to determine how best to conduct the procedure of sensor calibration. To optimize the accuracy of the sensors, the calibration procedure was implemented using mathematical methods that combined polynomial and exponential regression in a hybrid approach. The prototype can easily measure clothing pressure even during active movements, as seen in the detection of stable signals. In addition, since the system was specifically proposed as a wearable patch that can be easily attached and removed as necessary, it can also be used to standardize the value of clothing pressure in each movement.

The goal of this dissertation is to analyze the change of dress style based upon the 'Difference' theory developed by Gilles Deleuze and Michel Foucault. The methodology for this study consists of literary research, encompassing philosophy, aesthetics, dress and materials derived from internet and case study based upon the analysis of Deleuze and Foucault in the paintings by Bacon, $\acute{a}$, and Magritte. In order to develop the theoretical analysis tool for this study, the period and continuous theories of style change are examined in terms of 'identity' and 'resemblance.' A new framework for analyzing the changes of dress style based upon the 'Difference' theory derived from Deleuze's and Foucault's theories and from their interpretations of paintings was developed. This newly developed theory not only defines that dress style changes under the influence of various conditions such as designer's will, ideology, social structure and technology, but also interprets it as a newly-created style that has nothing to do with the original one. The characteristics that represent 'difference' in change of dress style are deformation, hybrid, absence and resemblance. They are derived from the Deleuze's and Foucault's interpretations of 'difference' represented in the paintings by Bacon, Vel$\acute{a}$zquez and Magritte.

This study analyzed expression types of dot patterns and derived out inherent characteristics to provide fundamental resources for advancement of high value added creative designs. As a result of the study, Firstly, the circular motive was used to form silhouettes or as a symbol of a decoration. Secondly, a simple form and color dot pattern was used to create one side, or a circular shaped accessory was used to be recognized as a construction line or a decoration line. Thirdly, textile printing is mainly used but handicraft and decorative images were used to add vitality through piece technique, embroidery, collage, cut-out, patch work, etc. Fourthly, different circular motives were integrated, partitioned and duplicated for abstract geometrical images. Fifthly, variations were added by mixing different dot patterns that are arranged regularly and irregularly in different sizes and gaps creating compounded designs with handicraft touches, different angles or on top of each other. Sixthly, hybrid images were created with rearrangement of dot patterns and by adding floral shapes, stripes or other abstract and geometrical shapes. Such various and creative attempts construct new formative beauty in fashion design and I believe that it can establish the development of unique images that satisfies the taste of today's consumers.

Sales forecasting is crucial for many retail operations. For apparel retailers, accurate sales forecast for the next season is critical to properly manage inventory and plan their supply chains. The challenge in this increases because apparel products are always new for the next season, have numerous variations, short life cycles, long lead times, and seasonal trends. In this study, a sales forecasting model is proposed for apparel products using machine learning techniques. The sales data pertaining to outerwear items for four years were collected from a Korean sports brand and filtered with outliers. Subsequently, the data were standardized by removing the effects of exogenous variables. The sales patterns of outerwear items were clustered by applying K-means clustering, and outerwear attributes associated with the specific sales-pattern type were determined by using a decision tree classifier. Six types of sales pattern clusters were derived and classified using a hybrid model of clustering and decision tree algorithm, and finally, the relationship between outerwear attributes and sales patterns was revealed. Each sales pattern can be used to predict stock-keeping-unit-level sales based on item attributes.

Structural design, generally engineering design, is a complex process combinding design knowledges and analysis techniques. While analysis techniques can be automated in an algorithmic fashion, relatively little work has been done in the area of the design automation. An effect approach method for the automation of the engineering design may be a hybrid system, in which design knowledges, specification requirements and interpretations are represented using an expert system methodology and numerically intensive operations of the design process are implemented using an algorithmic language such as FORTRAN. The purpose of this paper is concentrated on the knowledge of K-CLIPS(KAIST-C Language Integrated Production System) used to design and implement this hybrid system. In K-CLIPS, some representation methods : frame, production rule, fact and user defined function are used to construct the knowledge base. The hierarchical knowledges could be expressed more naturally with a little number of rules than other plain production systems.

This study aims to identify characteristics of neo-naturalism coming from periodical changes in the 21th society, culture based on naturalism and analyze the expressional and design characteristics of neo-naturalism on 2000s. For a research method, this study researched development of naturalism in fashion, and searched digital naturalism and ecology which are design paradigm effecting on neo-naturalism through literature research and preliminary study. Analyzing preliminary study on architecture, interior, fashion about digital naturalism and ecology design, concept of neo-naturalism identified and four expressional characteristics of neo-naturalism was classified, actual examples of neo-naturalism in 21th fashion were extracted and drew design characteristics. The results are as followings. Firstly, naturalism described nature as it is and developed according to the values and needs of the times. Naturalism in fashion showed natrual human body's curve, nature pattern and used natural materical focused on ideal beauty of nature. Secondly, neo-naturalism renews with the foundation of digital culture and ecology design paradigm, and focuses on the flexible possibility to express nature with digital, new media and formative art, and made the artificial nature uniting human-nature-environment as organic whole by ecology design paradigm. Thirdly, design of neo-naturalism divided four characteristics, nature's organic form, combination with the technology, ethical harmony with nature, global local design. The first characteristics of the nature's organic form are expressing silhouette of the nature's organic volume abstractly, the second ones of the combination with the technology are reinterpreting primitive nature contemporary with artificial sensibility of high technology, the third ones of the ethical harmony with nature are showing simple design and high-touch, and the forth ones of global local design are expressing cultural hybrid preserving vernacular design.

A hybrid ${\Delta}{\Sigma}$ modulator for audio applications is presented in this paper. The pulse generator for digital-to-analog converter alleviates the requirement of the external clock jitter and calibrates the coefficient variation due to a process shift and temperature changes. The input resistor network in the first integrator offers a gain control function in a dB-linear fashion. Also, careful chopper stabilization implementation using return-to-zero scheme in the first continuous-time integrator minimizes both the influence of flicker noise and inflow noise due to chopping. The chip is implemented in a 0.13 ${\mu}m$ CMOS technology (I/O devices) and occupies an active area of 0.37 $mm^2$. The ${\Delta}{\Sigma}$ modulator achieves a dynamic range (A-weighted) of 97.8 dB and a peak signal-to-noise-plus-distortion ratio of 90.0 dB over an audio bandwidth of 20 kHz with a 4.4 mW power consumption from 3.3 V. Also, the gain of the modulator is controlled from -9.5 dB to 8.5 dB, and the performance of the modulator is maintained up to 5 nsRMS external clock jitter.

Purpose: This study aims to introduce a hybrid MCDM model to support the selection of retail store location. Research design, data, and methodology: The hybrid approach of ANP and TOPSIS was used to address the location selection problem. The ANP technique was employed to compute the weights of the selection criteria, whilst the TOPSIS was used to rank alternatives. The proposed approach was then applied into a fashion company in Vietnam to select the best alternatives to be the retail store. Results: The results showed that Candidate 1 - Hai Ba Trung street is the most appropriate selection for locating retail stores. Conclusions: The proposed approach provides the decision makers with more useful methods than traditional ones. Therefore, the model can be applied to the location selection in all industries. In terms of academic contribution, the selection criteria proposed in the research can devote to the literature in the selection of location along with the concept of distribution channels. Additionally, the research also provides insight and guidelines for firms in making decision on retail store location based on limited resources to avoid the waste of funds. However, the results only answer to the context of Vietnam - a developing country. Thus, future research may be extended to developed countries where have better conditions.
