The purpose of this study was to provide the basic information necessary to efficiently run a coffee shop. It comparatively analyzes the relative importance and satisfaction of side menu selection characteristics through analyses on customer importance-satisfaction when selecting a side menu as well as their usage behavior of the side menu at coffee shops. According to reason price the analysis result on the differences in the coffee shop side menu importance and satisfaction, there was a difference because the importance of selecting a side menu was higher for the attributes of taste, health, packing & appearance, economics and personnel service compared to satisfaction among which the price of a side menu was found to be the top priority for improvement. The significance of coffee shop side menu for the respondents prior to usage as well as their satisfaction after usage was evaluated in order to comparatively analyze the relative importance and achievement of each characteristic through the IPA. The result indicated that the variables positioned in the Concentrate Here area (II) were related to economic feasibility such as reasonable price, appropriate price of set menu, telecommunication company affiliated service and coupon usage and point accumulation. As for the Keep up the Good Work area (I), there were many variables regarding personnel service including taste of side menu, blending with coffee, clean packing, clean packaging, staff's side menu knowledge, staff's quick response, staff's politeness and staff's sincere response. As for the variables in the Low Priority area (III), health variables on health such as nutritional value, eco-friendly food materials and calories were observed.

Since the use of textile has become more extensive and applied for various products, today, the importance of utility, ornament and civilization of textile is emphasized. Textile design should be able to satisfy the designer's creativity and his/her world of art. Moreover, it should be appropriate for the industrial technology circumstances, and taste of consumers. In Korea, traditional culture has been extremely valued, allowing people to be more interested in textile designs derived from traditional cultural. Therefore, designs inspired by the spirit and sense of traditional patterns has been used to develop modern textile designs. Prior research on products, however, show that cultural motive was insufficient, therefore, in this research the purpose is to design textiles and to develop Korean neckties, an essential component of men's attire, by adapting Korean traditional patterns. In order to conduct the research, first, numerous parers on Korean traditional patterns have been studied to select fundamental data about the development of necktie textile designs. Second, Korean traditional patterns were applied while following the target and concept, and two pieces of necktie textile designs have been suggested. Patterns had been designed by hand drawing and CAD system, they have been suggested as a portfolio. As a result, this article suggests new necktie designs utilizing Korean traditional patterns and, attempts to develop particular pattern designs, which have power to accommodate globalization and to express the special qualities of Korea.

Generally, printers are common for users to use for public use over a wired or wireless local area network. The number of printers in the same network is increasing, and management of multiple printers is needed. To do this, a program that drives two or more printers and a computer connected by a wired or wireless network. When a computer's control department receives a print command for a designated file, it executes the steps of receiving status information from the printer, selecting the printer, and sending the print command execution. As a method of research, we presented a method for selecting differentiation from this study through prior art research and literature research. Therefore, the purpose of the study is to distribute smart print commands according to real-time status information of many printers to increase the efficiency of the printer's management, and to distribute print commands according to the cumulative and usable workload of many printers so that parts replacement of many printers can be instantaneously performed.

The purpose of this study was to realize and apply Taekwondo's technology and the fact that actors on stage and screen have much in common. In the meantime, there have been many prior studies on the development of the theoretical field. However, there is a slight lack of practical development and development plans, and it is time to improve. This seems to be a lack of practical experience leading to the creation of physical images. In that sense, I think that it should be supported by the complement of concrete and detailed research that seeks to make changes in open technology significantly. Considering this situation, it is necessary to further develop the practical field in parallel with the theoretical field. Therefore, I suggested the principle of physical behavior through Taekwondo technology and the development of acting skill. The performance training using these taekwondo techniques is meaningful research.

The purpose of this paper is to present a smart QR code recording system and a method of non­storage data delivery that transforms the original data into a form of URL information by encrypting it and encoding the URL information into a QR code so that the QR code can be written and decrypted in a medium without storing the original data. The method of the study was presented by the prior art study and the literature research. Analysis results show that the system is built on the online administration server. The data input signal matching secret code is stored in DB, the QR code generation command converts input data from the password DB to the password information combined into the subordinate locator of the admin server's domain name, URL code. Therefore, the smart QR method of data management (recording and providing) indicates that there are no limitations in the ease and space of use or obstacles to capacity use.

This study is to analyze works of Memphis design in the 1980s, which captured the appearance of a diversified society since the 20th century, and to present practical designs that can communicate with the public through the formulation of indoor lighting. As a research method, the background of the occurrence of Memphis groups, the theoretical background and the formative features of Memphis designs are considered around literature and prior research. The research applied Memphis's formative characteristics, colors and patterns to incorporate newly formulated designs into lighting. Lighting lamps in the forms that have made small changes to basic shapes show not only its functionality and decorability, but also its scalability as a formative language that conveys the emotions contained within humans. In addition, the choice of materials according to the changes in sculpture in the production of the work will suggest the possibility of creating a new formative art.

Cracks affect the robustness of infrastructures such as buildings, bridge, pavement, and pipelines. This paper presents an automated crack detection system which detect cracks in diverse surfaces. We first constructed the combined crack dataset, consists of multiple crack datasets in diverse domains presented in prior studies. Then, state-of-the-art deep learning models in computer vision tasks including VGG, ResNet, WideResNet, ResNeXt, DenseNet, and EfficientNet, were used to validate the performance of crack detection. We divided the combined dataset into train (80%) and test set (20%) to evaluate the employed models. DenseNet121 showed the highest accuracy at 96.20% with relatively low number of parameters compared to other models. Based on the validation procedures of the advanced deep learning models in crack detection task, we shed light on the cost-effective automated crack detection system which can be applied to different surfaces and structures with low computing resources.

Deep learning has made rapid progress in recent years and is affecting various fields and industries. The art field cannot be an exception, and in this paper, we would like to explore and experiment and analyze research fields that creatively generate 2D images in 3D from a visual arts and engineering perspective. To this end, the original image of the domestic artist is learned through GAN or Diffusion Models, and then converted into 3D using 3D conversion software and deep learning. And we compare the results with prior algorithms. After that, we will analyze the problems and improvements of 2D to 3D creative generation.
