레이저 가공기술은 재료가공 분야에서 넓은 응용분야를 가지고 있으며, 특히 절단, 용접, 열처리 등의 가공분야에서 고정밀도와 자동화의 용이성으로 인해 생산성이 높은, 고부가가치의 첨단응용 기술로 부각되고 있다. 특히 레이저절단은 타 절단법에 비교되는 절단정도, 열영향, 생산성, 작업 환경등의 각종 우위성으로 박판 및 후판절단분야에서 급속한 보급을 보이기 시작하였다. 현재 대 부분의 레이저 가공기는 CNC화 되어가고 있는 추세이며, 레이저 절단의 경우 생산성증대 및 고 정밀화를 위하여 CAD/CAM인터페이스에 의한 자동화가 필연적인 상황이다. 뿐만아니라 고출력 레이저 발전기를 가공 기본체에 탑재한 탑재형 레이저가공기의 출현으로 대형부재의 절단이 가능 하게 되었으며, 더불어 절단공정의 무인화를 지향하는 각종 시스템이 개발되고 있다. 이와 같은 무인화, 생산성증대, 작업시간단축과 러닝 코스트 및 재료의 절감을 위한 노력의 일환으로 컴 퓨터에 의한 자동 및 반자동 네스팅 시스템의 개발을 들 수 있다. 레이저에 의한 2차원 절단응 용분야에서의 네스팅작업은 설계가 끝난 각 부품의 절단작업의 전단계로서 수행되며, 일반적으로 네스팅공정이 완료되면 절단경로를 결정하고 가공조건과 함께 수치제어공작기계의 제어에 필요한 NC코드를 생성하게 된다. 최근에는 이와 같은 네스팅 시스템이 일부 생산현장에 적용되고 있 으나 이러한 시스템들의 대부분이 외국에서 개발된 것을 수입하여 사용하는 실정이다. 2차원 패턴의 최적자동배치문제는 비단 레이저 절단과 같은 열가공 분야에서 뿐만 아니라 블랭킹 금형, 의류, 유리, 목재등 여러분야에서 응용이 가능하며 패키지의 국산화가 시급한 실정이다. 네스 팅작업은 적용되는 분야에 따라 요구사항과 구속조건이 달라지며 이로 인해 알고리즘과 자료구 조도 달라지게 되나 공통적인 목표는 주어진 영역안에서 겹침없이 배치하면서 버림율을 최소화 하는 것이다. 지난 10여년간 여러 산업의 응용분야에서는 네스팅시스템의 도입이 활발하게 이 루어지고 있는데 수동에 반자동 및 자동에 이르기까지 다양하나 자동네스팅시스템의 경우 배치 효율의 신뢰성이 비교적 부족하기 때문에 아직까지는 생산현장에서 기피하는 실정이다. 배치알 고리즘의 관점에서 볼 때 이러한 문제들은 NP-complete문제로 분류하며 제한된 시간안에 최적의 해를 구하기가 가능한 조합 최적화 문제로 알려져 있다. 따라서 이 글에서는 레이저 절단분야 에서의 네스팅시스템에 관한 개요와 최근의 연구동향 그리고 몇 가지 전형적인 네스팅 알고리 즘들을 소개하고 비교분석을 통해 개선점을 간략하게 논의하고자 한다.

The purpose of this study is to analyze the Muslim fashion that has recently appeared in the global fashion collection to see how the global fashion brand expresses Muslim's traditional costumes so as to provide references in design development to prepare for the larger Muslim fashion market in the future. In order to analyze Muslim fashion, keywords related to Muslims such as "Muslim," "Islamic fashion" and "hijab" were searched on Google, Samsung Design Net and Vogue websites, and a total of 370 fashion photos were selected for the final data, which was judged to reflect Muslim fashion styles after a review by four clothing experts. Muslim fashion styles have the following characteristics: Above all, the use of veils was most noticeable, with many T-shaped loose long tunic dresses. The hijab, which had the highest proportion of veils, was used to produce various images with wide range of materials and colors. Achromatic colors were the most common, but more than three colors were used to create an exotic image. There have also been cases of using direct religious images such as arabesque patterns and mosques and Muslim priests. As a final, Muslim fashion styles were studied follow: first, a unique style using a veil. Second, conservative style with minimal exposure, third, restrained long-and-lose fit style, fourth, exotic style by elaborate pattern. The domestic fashion industry is also expected to generate economic demand if it is designed with reference to such collection trends along with market research on Muslim consumers.

The purpose of this study is to explore university students' Hanbok rental behavior and to examine factors that influence their intention to rent Hanbok. Questionnaires were distributed in Universities in the Seoul metropolitan area, and the final 202 responses were used for data analysis. For data analysis, descriptive statistics, factor analysis, cluster analysis, t-tests, and multiple regressions analysis were used. Sixty-one percent of those who have experienced Hanbok rental said they rented Hanboks to experience tourism and 22 percent said they rented Hanboks to take pictures, and the main rental places are tourist attractions such as Jeonju Hanok Village. Respondents indicated that the design and color of Hanbok were important product attributes when they consider renting a Hanbok. They also indicated that the opinions of other users posted on the Internet/Social Network were their main source of information for Hanbok rental. The result of cluster analysis showed that there were two groups of Hanbok rental consumers based on clothing consumption values: novelty-seeking group and practicality-seeking group. The two groups were different in terms of few factors of the benefit sought of Hanbok rental, product attributes, and information sources. Regression analysis revealed that traditional culture perception, purpose-built Hanbok pursuit benefit, pragmatic pursuit benefit, attitude toward Hanbok, and the previous Hanbok rental experience significantly affected respondents' intention to rent Hanbok. Based on the results, this study summarizes the key features of each group and provides suggestion for developing strategic marketing activities.

This research is a study on up cycling design to protect nature in order to postpone global warming to the maximum extent possible as it has been a serious global issue to the fashion industry and even to individual consumers. This research focuses on the ways to use wedding dress, one of the clothes made of synthetic fiber, which is a major cause of global warming. Among clothing from the 19th century, two styles of clothes, Bustle style and Art Nouveau style were analyzed ranging from their underwear styles to outwear styles through collections in books and museums. Two styles of dress using drawers, chemise, and corset as basic underwears were manufactured. All the fabric and subsidiary materials except for parts of underwears were made with discarded wedding dresses. It was developed for rental clothing which women could try on Western costume, from underwears to outwears. First, for bustle dress, woman put on basic underwears, then bustle, and bustle-type petticoat. Dress is a two-piece type, and it was made to put on detachable train on the back of skirt. Second, based on the Art Nouveau style clothes, our-glass style dress consists of petticoat, one-piece over drawers, chemise, and corset. After putting on drawers, both chemise, and corset were the same as Bustle Style. This research is a practical way of realizing sustainable design. The aim of the current work is to provide educational effect on the development of rental clothes which upcycle wedding dress and let women experience other cultures.

Unlike nail care, nail art is a field with strong decorative elements that decorate the surface of the nail. In line with the trend of the times, which freely expresses one's personality, nail art is establishing itself as a definite and a key area in the beauty industry. Currently, design creation and technology developments are important, with the release of various nail materials and new trends that spread through mass media. Despite the great developments in the nail beauty industry, there is a lack for nail artists. Due to this fact, it is considered a necessary to combine nail art with the contemporary art styles, which have various motifs of design, and to study nail art design using them. In response, this study selected art from the Rococo era, where delicate and colorful decorative elements were at their peak, to consider the artistic styles of the time and present them in various nail designs. This study would like to expand the scope of new nail designs by suggesting colorful and feminine designs to women, who are the main customers of nail salon. In addition, the purpose of this study is to provide nail artists with basic materials that can be used in creative ideas and expressions, such as 2D and 3D nail designs, and composite nail design art, which are the art areas for nail art.

We present a supervised learning method that estimates the simulation parameters required to simulate the fabric from the static drape shape of a given fabric sample. The static drape shape was inspired by Cusick's drape, which is used in the apparel industry to classify fabrics according to their mechanical properties. The input vector of the training model consists of the feature vector extracted from the static drape and the density value of a fabric specimen. The output vector consists of six simulation parameters that have a significant influence on deriving the corresponding drape result. To generate a plausible and unbiased training data set, we first collect simulation parameters for 400 knit fabrics and generate a Gaussian Mixed Model (GMM) generation model from them. Next, a large number of simulation parameters are randomly sampled from the GMM model, and cloth simulation is performed for each sampled simulation parameter to create a virtual static drape. The generated training data is fitted with a log-linear regression model. To evaluate our method, we check the accuracy of the training results with a test data set and compare the visual similarity of the simulated drapes.

The e-commerce fashion market has experienced a remarkable growth, leading to an overwhelming availability of shared information and numerous choices for users. In light of this, chatbots have emerged as a promising technological solution to enhance personalized services in this context. This study aimed to develop user-product attributes for a chatbot-based personalized fashion recommendation service using big data text mining techniques. To accomplish this, over one million consumer reviews from Coupang, an e-commerce platform, were collected and analyzed using frequency analyses to identify the upper-level attributes of users and products. Attribute terms were then assigned to each user-product attribute, including user body shape (body proportion, BMI), user needs (functional, expressive, aesthetic), user TPO (time, place, occasion), product design elements (fit, color, material, detail), product size (label, measurement), and product care (laundry, maintenance). The classification of user-product attributes was found to be applicable to the knowledge graph of the Conversational Path Reasoning model. A testing environment was established to evaluate the usefulness of attributes based on real e-commerce users and purchased product information. This study is significant in proposing a new research methodology in the field of Fashion Informatics for constructing the knowledge base of a chatbot based on text mining analysis. The proposed research methodology is expected to enhance fashion technology and improve personalized fashion recommendation service and user experience with a chatbot in the e-commerce market.

This research proposes the on-stage costumes for the play Hamlet of Shakespeare performed by Yunheedan Guhri Pae - the Street Theater Troupe. Stage costumes have an important role in displaying the characteristics of each characters to the audience and has big visual effects. However, in order to design the costumes in the object viewpoints of the audience, the survey on the images of the characters who had actually watched the performance was taken place and proposed the costume design according to the results of the survey. Hamlet a: This result was applied to propose a sweater in black color, black leather pants and vest. Hamlet b: This result was applied to propose hooded coat in purple in middle level of brightness and color spectrum and yellow coat. For free image, loose pants in blue and vest in the same color tone were proposed. Gertrude a: This result was applied to use purple (violet) with reddish tone to propose the formation of a dress applying tailored suit. Gertrude b: This result was applied to propose purple gown and the one-piece dress with black laces. Ophelia a: This result was applied to propose feminine white dress and cape in purple color tone. Ophelia b: This result was applied to propose dyed and weaved clothes. Through the surveys as above, the images of each character was driven in adjectives, and using the results driven from the brightness, coloration, and color, color images were proposed. Only one costume cannot make up for the stage costumes and because it exists as an element of stage production, it is true that costumes are limited in some areas. However, that limit can become the motive of the costume. There is a limit, which the designer cannot produce the costumes as he or she had designed but I believe it is the center of the on-stage customers to display the characteristics of the characters according to the given concept. The limit of this research is the fact that because the costumes were designed so they fit the conditions already given, thus it was difficult to regard the process of designing and producing the costume as a project done according to the interaction. And in the future, if it is possible, I wish for the joint research with the people responsible for stage art to take place as a practical stage art. It was possible to produce practical costume since they were produced for actual performance and the production of costumes considering the dance steps, line of flow, and acting, was able to reduce the trial and error on stage. Through this research, I felt that the understanding and smooth interaction on diverse other areas not limited to the costume design should be taken place and believe that this was a research that proposes new research method since there had been only a few previous research regarding the on-stage costumes for actual performances. Therefore, this research had depended on the surveys given to the audiences to endow objectivity, however, I wish this research can contribute to defining effective process and methods for the on-stage costumes with more active researches with diverse methods and in diverse areas. I am sorry that the costume production for all the characters and all the scenes in Hamlet couldn't be done due to many limitations. As the following research assignment, I am planning on designing the costumes for all the scenes.

The purpose of this study was to examine the thermal comfort characteristics of the garments for school, textile and bank worker's uniform. The garments selected for this study were frequently used in Taegu area in terms of design and material used for making garments by the survey for the study The human subject tests were performed to determine the thermal comfort characteristics of garments including thermal, humidity, and wearing sensation and the data were analysed statistically. The results of the study were as follows: 1. According to the result of the survey jacket was mostly used as a school uniform for both male and female high school students. The survey showed that 93% of male students wore 'neck T-shirts' and dimensional fitness for the school uniform got suitable at 2~3 grade high school students. In terms of human subject tests, most students rated 'uncomfortable' in wearing sensation of their school uniform. One of this reason was due to the humidity sensation and air velocity sensation. Level of significance of the thermal sensation for gender difference was higher in hands and feet of the subjects than in chest and thigh of them. 2. According to the result of the survey jacket with zipper was mostly used as a textile worker's uniform. The result of the survey indicated that some textile workers are wearing their inner wear (38.7% for upper and 46.6% for lower). In the human subject tests, about 50% of subjects rated 'comfortable to slightly comfortable' for wearing sensation of the textile worker's uniform. It showed that the female subjects of the humidity sensation was rated higher than the male subjects of the humidity sensation, while the male subjects of the thermal sensation was rated higher than the female subjects of the thermal sensation. There was a closer correlation with the subjective thermal sensation for textile worker's uniform in center parts of the subjects such as back and waist than exposed parts. 3. The result of the survey showed that 70% and 23% of the female banker uniform were blouse and jacket, respectively and 75% and 25% of the male banker uniform were jacket and T-shirt, respectively. All interviewee rated trousers and skirts that were used for their lower. 4. The result indicated that 50% male and 67.7% female subjects for the banker uniform rated 'slightly comfortable for the comfort' sensation. 50% male subjects rated 'neutral' and about 50% female subjects rated 'slightly warm to neutral' for the thermal sensation. In addition, The result showed that 75% male subjects for both upper and lower rated 'neutral' for the humidity sensation and also 75% female subjects rated 'neutral to slightly dry'. Thus, there was no significant different between gender. 5. In the thermal sensation of the subjects for the banker's uniform by parts, 50% subjects rated 'neutral' for their body parts, including head, neck, back, waist, hip, lower arm, and thigh. The extremely cold parts were hands and feet for both male and female subjects.
