In this study, natural dyeing using Polygonum tinctoria was performed with linen, ramie, and hemp, which are biodegradable cellulose fibers, considering environmental aspects. In particular, the impacts of alkali NaOH and reducing agent Na2S2O4 were examined, and the possibilities of minimizing the use and reusing the dye were explored. The surface dye concentrations were found to be in the following order: hemp>linen>ramie. With the increase in all additives, the L* value decreased, and the ⊿E and K/S values increased gradually. When Na2S2O4 was 1g/L, the surface color of the dye appeared uniformly from the NaOH concentration of 0.4g/L (pH 10.84). When NaOH was 0.4g/L, the K/S values of linen and ramie increased rapidly after 0.4g/L of Na2S2O4, and hemp maintained a stable color from 0.6g/L of Na2S2O4. With the increase in the dye concentration from 1 to 6g/L, all the fibers were dyed uniformly. The K/S value increased or higher doubled upon repeated dyeing six times for 5 min than when dyed only once for 30 min. Therefore, the linen, ramie, and hemp fibers dyed repeatedly exhibited good washing, rubbing, and colorfastness to perspiration, which was rated between 4 and 4-5, and that to light was rated as 5. Moreover, no discoloration due to sunlight was observed. Finally, linen exhibited a bacterial reduction of 99.9%, thereby indicating its excellent antibacterial property.
This study investigated the distribution behaviors of PM2.5 and PM10 at two air quality monitoring sites, Go-eup (GO) and Backseokeup (BS), located in Yangju City, South Korea. The amounts of emissions sources of pollutants were analyzed based on the Clean Air Policy Support System (CAPSS), and the contribution rates of neighboring cities were enumerated in Yangju. Yangju has a geological basin structure, and it is a city with mixed urban and rural characteristics. The emission concentration of particulate matter was affected by geological and seasonal factors for all sites observed in this study. Therefore, these factors should be considered when establishing policies related to particulate matter. Because the official GO and BS station sites in Yangju are both situated in the southern part of the city, the representativeness of both stations was checked using correlation analysis for the measurement of PM2.5 and PM10 by considering two more sites-those of Bongyang-dong (BY) and the Gumjun (GJ) industrial complex. The data included discharge amounts for business types 4 and 5, which were not sufficiently considered in the CAPSS estimates. Because the 4 and 5 types of businesses represent over 92.6% of businesses in this city, they are workplaces in Yangju that have a significant effect on the total air pollutant emission. These types of businesses should be re-inspected as the main discharge sources in industry, and basic data accumulation should be carried out. Moreover, to manage the emission of particulate matter, attainable countermeasures for the main sources of these emissions should be prepared in a prioritized fashion; such countermeasures include prohibition of backyard burning, supervision of charcoal kilns, and management of livestock excretions and fugitive dust in construction sites and on roads. The contribution rates by neighboring cities was enumerated between 6.3% and 10.9% for PM2.5. Cooperation policies are thought to be required with neighboring cites to reduce particulate matter.

The development of environmentally friendly products and services has become a trend, and the development and utilization of eco-friendly textiles with economic value is gaining attention as a new business model. Analyzing and identifying trends and developments in eco-friendly textiles can provide important information and insights for various stakeholders such as companies, governments, and consumers to help them achieve sustainable growth. For this study, we collected and analyzed data from newspaper articles mainly covering the textile and fashion sector from 2000 to June 2023. A total of 12,331 articles containing the keyword 'eco-friendly textiles' were collected, and after performing morphological analysis on the extracted data, Latent Dirichlet Allocation and Dynamic Topic Modeling analysis were performed to identify topics by year. The results of the study are expected to provide strategic guidance and insights for the sustainable development of the textile industry, thereby helping to promote the research, development, and commercialization of eco-friendly textiles.
Purpose - "Showrooming" refers to the phenomenon where a shopper visits a store to see and compare products but makes the purchase online at a lower price. Surveys on showrooming activities at home and abroad indicate that a significant number of consumers pursue showrooming activities. The advent of "showroomers," who engage in buying activities, hovering both on and offline, while selectively choosing sales channels to suit their needs, is powerful enough to erode the borders between channels and bring about seismic changes in the distribution industry. However, surprisingly, there has been no in-depth discussion on showrooming. This study seeks to theoretically investigate what impact personal characteristics have on showrooming preferences and attitudes in a multi-channel environment. Specifically, assumptions have been made that price perception, perceived performance risk, and trust in online shopping not only have a direct impact on showrooming attitudes but also indirectly affect it through the means of contact motivation. Research design, data, and methodology - To test the hypotheses, this study conducted a survey of male and female shoppers, ages 20 through 40s, who live in metropolitan areas, and have actively showroomed fashion items in the last six months. A clothing item usually purchased after a careful decision-making process was chosen as the target product of the study. The survey was conducted between October and November 2014, using a professional survey service provider. A total of 200 surveys were collected, of which 198 were used for analysis. Conceptual model Structural Equation Modeling (SEM) and Amos 18.0 were employed for data analysis and model verification. In addition, following the confirmatory factor analysis and measurement model analysis, the theoretical model that corresponds to the research model was analyzed. Results - Analysis results show that price perception, perceived performance risk, and trust in online shopping have a statistically significant and positive (+) impact on showrooming attitudes. In addition, in terms of the indirect influence of price perception and perceived performance risk on showrooming attitudes through means of contact motivation, price perception had a statistically significant and positive impact on means of contact motivation, whereas perceived performance risk did not have a statistically significant impact on it, with the relevant hypothesis rejected. Conclusions - These analysis results imply that the ultimate goal of consumers is to maximize their shopping benefits by selectively and strategically taking advantage of different channels in a complementary manner. This study presents many implications for distributors to encourage a deep understanding of showrooming consumers who have complicated consumption behaviors and to build channel integration strategies. This study has limitations in theoretical and practical implications. Therefore, subsequent studies need to focus on verifying that showrooming activities are based on reasonable and planned decisions by applying the theory of reasoned or planned behavior. In addition, the scope of the study should expand to include web showrooming, where consumers conduct product research online and purchase offline.

Recently, the retail industry has created efficient store operations, and has differentiated customer service through the future store. The intelligence of these stores is being applied by using technologies such as the Internet of Things (IoT), and the business process is being improved through this. The process also focuses on efficient store operations and service developments to provide customers with shopping convenience. The change in trends in the industry means that domestic distribution has already reached maturity. Even in countries where retail industries are mature, such as the U.S. and Europe, recent trends are moving toward maximizing operational efficiency and customer service. The reason is that many retailers have already reached saturation and survived the competition. This paper is a study of a drive-through service for automation and efficiency in receiving service after ordering by a customer of the distribution store. When ordering a product being purchased by a customer, the product picking process is done in a timely fashion through a picking scheduling agent. When the customer enters the store parking lot, a service supports the entry of information and finding a parking place so the customer can quickly pick up the goods. The proposed service can be applied to a retail store drive-through system, the distribution store's delivery system, the digital picking system, and indoor/outdoor large parking management systems, and it is possible to provide one-dimensional customer service through the application of IoT technology.
Character conveys rich storytelling and various design elements. Domestic characters are changing and developing in various forms through SNS and offline sources, which are being developed in the aspect of contents industry. The purpose of this study is to find out and discuss the factors that character users are using Korean characters as storytelling and color factor. In terms of storytelling, they prefer adventure, fantasy, absurd and humorous stories. In terms of color, it seems that they prefer a character with simple and simple color/ warm color and warm / cute color composition. On the other hand, characters with a simple story, which is the main subject of early childhood education, fashion, or toys in the aspect of storytelling, are not preferred. In terms of color, it was shown that 4 or more colors were combined without a main color. These main colorless characters gave complex feelings that are not preferred. In terms of storytelling, it is necessary to develop and develop the contents of OSMU(One-source Multi use) through story development with adventure and fantasy structure. In terms of color, it is necessary to configure the user with a simple and simple color which is preferred by the users. Also, the assembly robot toy character needs to increase the satisfaction of the character through simple color composition. As a result of this study, the factors that satisfy the users in terms of storytelling and color are derived. These results will contribute to the development of theoretical aspects, storytelling aspects, and character design industry aspects. Despite the significance of the above paper, it was inevitable to limit the research on the analysis of the storytelling of specific characters, the research through the color analysis framework, the accurate data analysis on the color analysis, and the simple comparative analysis of one.
Software license agreements, to be useful in the mass market, could not be individually negotiated, and had to be standardized and concise. The software license agreement needs to be presented to the licensee-users in a fashion that would allow for mass distribution of software, also for it to enforceable, that would draw the users' attention to the terms and conditions under which the publisher allowed the use of the software. These needs have been accomplished, with or without fail, through so called the "shrink-wrap licenses" Shrink-wrap licenses purpose to transfer computer softwares to their users by defining the terms and conditions of use of the software without implicating the "first sale doctrine" of the Copyright Act. These shrink-wrap licenses have become essential to the software industry. However, in USA, the law applicable to these licenses has been unclear and unsettled. Courts have struggled to develop a coherent framework governing their enforceability. Meanwhile, the National Conference of Commissioners on Uniform State Laws ("NCCUSL") in USA promulgated the Uniform Computer Information Transaction Act ("UCITA") governing contracts for computer information transaction on July 29, 1999. One clear objective of UCITA was to settle the law governing the enforceability of shrink-wrap licenses. In these respects, this paper first introduces the various forms that shrink-wrap licenses take(at Part II. Section 1.), and explains the main advantages of them(at Part II. Section 2.) Here it shows how shrink-wrap licenses value themselves for both software publishers and users, including that shrink-wrap licenses are a valuable contracting tool because they provide vital information and rights to software users and because they permit the contracting flexibility that is essential for today's software products. Next, this paper describes the current legal framework applicable to shrink-wrap licenses in USA(at Part III). Here it shows that in USA the development of case law governing shrink-wrap licenses occurred in two distinct stages. At first stage, judicial hostility toward shrink-wrap licenses marked such that they were not enforced pursuant to Article 2 of the Uniform Commercial Code. At second stage, courts began to recognize the pervasiveness of shrink-wrap licenses, their indispensability to the rapidly expanding information technology industry, and the urgent need to enforce such licenses in order to maintain low prices for consumers of computer hardware or software, resulting in the recognition of shrink-wrap licenses. Finally, in view of the importance of UCITA, this paper examines how it will affect the enforceability of shrink-wrap licenses(at Part IV). The drafters of UCITA, as well as the scholars and practitioners who have criticized it, agree that it validates shrink-wrap licenses, provided certain procedural protections are afforded to purchasers. These procedural protections include the licensee end-user must (i) manifest his assent to the shrink-wrap license, (ii) have an opportunity to review the shrink-wrap license, (iii) have a right to return the product without costs.
In today and near future, most of the commercially manufactured IT products will be evolved into software convergence product. Recently, the embedded software products is called as 'Software Convergence Products.' This phenomenon does not simply show the trendy fashion, but has the seriously implication that the functionalities of IT product is accomplished and evolved via software technology, not via mechanical nor electrical means. It will become true that the quality of the convergence product is dominantly governed by the software it uses. Meanwhile, we are facing with the threatening fact that software defects in the mass products will requires tremendous amounts of cost proportional to the quantity of the product. We can remind ourselves of the disasters that have been already happened, such as Automotive recalls, Smart-phone recalls, and others. In software engineering, there have been large amount of work done in software quality improvement for the past couple of decades. Software process improvement, and testings are the representative ones. But we are facing with limitations of those traditional approaches in current convergence industry; exponentially increasing software sizes and rapid changes in software technology. In this paper, we analyze the characteristics of the software convergence industry, the limitations of the traditional Software quality improvement approaches. We suggest a new approaches in software quality improvement in different angles of thought and philosophy.

When writing historical dramas, there was an argument that restoring the language of the times was the responsibility of the playwright, but no full-scale research was done. There was no collaborative study between playwrights and Korean Language scholars. So far, many playwrights have considered it the responsibility of Korean Language scholars to discover and restore language. However, it is a medium that can easily meet the public like a play or movie, and it should have a great responsibility for creation. Language changes with time, so restoring the language of the time in plays and scenarios can lead to difficulties in communicating with modern audiences. However, the change of language according to the times means that it captures the social image and fashion of the time Therefore, language restoration in historical dream means that scenes and backgrounds can be described more realistically. Restore of language is not just necessary to improve the creative environment; it should be understood as the responsibility of the artist to meet the ability of the audience to understand the language of the times already learned. The playwright who writes the historical drama should not only learn the grammar of the background era, but also find out the lost pronunciation and the changed vocabulary so that he can use various dialogues.
