In a situation where the importance of eco-friendly fashion is growing, this study adds to the needed research by analyzing consumption value satisfaction factors, brand image, and repurchase intentions of eco-friendly fashion products. During the investigation, the impact of gender was also accounted for to establish an effective marketing strategy. In June 2024, 250 surveys were evaluated from domestic consumers with experience purchasing eco-friendly fashion products. Descriptive statistical analysis, factor analysis, reliability analysis, and regression analysis were performed. Five factors were measured to determine satisfaction with the consumption value of eco-friendly fashion products: emotional value, functional value, social and situational value, passive value, and rare and eco-friendly value. Empirically subdividing satisfaction with eco-friendly fashion as recognized by consumers reveals meaningful findings about consumption value. Among the factors of consumption value satisfaction with eco-friendly fashion products, functional value, social and situational value, and rare and eco-friendly value all positively affected repurchase intention. The consumer’s gender also made a difference in satisfaction. Considering these results, the marketing effect of eco-friendly fashion can be increased.

To control western flower thrips (Frankliniella occidentalis), a significant pest of peppers, the control effects of eco-friendly agricultural materials were tested when treated alone and in combination. The control effects of yellow sticky roll traps installed on the stem, predatory natural enemy (Hypoaspis miles) inoculated on the stem, and plant extracts (50% custard apple seed oil + 10% cinnamon extract) sprayed on the foliage were 45.3%, 36.6%, and 50.2%, respectively, when treated individually. Meanwhile, when three eco-friendly agricultural materials were comprehensively applied, the control effect was maintained between 62.4% and 80.9% compared to untreated conditions during the pepper harvesting season. These methods can be utilized for the eco-friendly control of western flower thrips in pepper greenhouses.

In this study, we introduce a novel TiN/Ag embedded TiO2/FTO resistive random-access memory (RRAM) device. This distinctive device was fabricated using an environmentally sustainable, solution-based thin film manufacturing process. Utilizing the peroxo titanium complex (PTC) method, we successfully incorporated Ag precursors into the device architecture, markedly enhancing its performance. This innovative approach effectively mitigates the random filament formation typically observed in RRAM devices, and leverages the seed effect to guide filament growth. As a result, the device demonstrates switching behavior at substantially reduced voltage and current levels, heralding a new era of low-power RRAM operation. The changes occurring within the insulator depending on Ag contents were confirmed by X-ray photoelectron spectroscopy (XPS) analysis. Additionally, we confirmed the correlation between Ag and oxygen vacancies (Vo). The current-voltage (I-V ) curves obtained suggest that as the Ag content increases there is a change in the operating mechanism, from the space charge limited conduction (SCLC) model to ionic conduction mechanism. We propose a new filament model based on changes in filament configuration and the change in conduction mechanisms. Further, we propose a novel filament model that encapsulates this shift in conduction behavior. This model illustrates how introducing Ag alters the filament configuration within the device, leading to a more efficient and controlled resistive switching process.

Although interest in eco-friendly fashion products is increasing among scholars and industry leaders, the concept of eco-friendly products remains unclear, preventing consistent assessment of which fashion products are eco-friendly. This study conducted a content analysis of eco-friendly product information from 87 domestic and 102 foreign brands to reveal key standards for categorizing eco-friendly fashion products. Product characteristic information was coded according to the four material-based standards (i.e., organic material, regenerative material, alternative material, and sustainably produced/upcycled material). Consistency between coders was confirmed by Cohen’s kappa. In results, eco-friendly fashion products are categorized by four material-based standards and two certification standards (i.e., certified, not certified). Among the four material-based categories, the greatest number of domestic and foreign companies produced eco-friendly products that were classified as the regenerative material group. In addition, companies acquired eco-friendly certifications related to the use of organic, regenerative, and alternative materials. The greatest number of eco-friendly material brands used for eco-friendly fashion products belonged to the regenerative material group. Based on the study results, a typology of eco-friendly products was suggested. This typology can benefit practitioners and academics by highlighting a need for classification system for the eco-friendly fashion products, as well as by providing insight into the categorization of eco-friendly fashion products.

PURPOSES : Sprinkler facilities play a crucial role in extinguishing fires in the early stages of a building blaze. Data indicate that more than 96% of fires are suppressed by sprinklers before growing out of control. However, corrosion and pitting of the sprinkler piping can reduce system performance as facilities age. The purpose of this study is to develop an eco-friendly water-soluble corrosion inhibitor to improve the reliability and longevity of sprinkler piping. METHODS : This study compared and analyzed silicate-based sprinkler piping shrinkage agents as corrosion inhibitor against existing commercial options. Tests were conducted to evaluate reactivity with fire extinguishing water, including electrolyzed reduced water and normal water. The anticorrosive performance of the silicate-based corrosion inhibitor was evaluated under various conditions to establish suitability before potential development or commercialization. RESULTS : The new corrosion inhibitor demonstrated eco-friendly performance. In testing, none of the primary four hazardous substances that pose the most risk of harm to the human body (specifically, arsenic (As), lead (Pb), cadmium (Cd), and mercury (Hg)) were detected. The inhibitor effectively reduced corrosion of carbon steel (SPP), with weight loss rates averaging 0.12% and not exceeding 0.27%. For copper (CDA 110) weight loss rates were up to 0.03%. Testing under constant temperature and humidity conditions show that the inhibitor kept weight loss was below 0.002 g, with no significant numerical value for the weight loss rate. Overall, the results indicate the potential for an environmentally-safe corrosion inhibitor. CONCLUSIONS : The optimal silicate-based sprinkler system can provide real-time sensor information such as oxygen saturation, pH concentration, and total dissolved solids (TDS). These metrics are closely related to the aging process. By linking this system with an aging monitoring solution, maintenance costs and safety could be improved over the lifespan of the sprinkler system. The sensors and monitoring capabilities are expected to enhance maintenance efficiency and equipment reliability.

Since their initial development in 2012, triboelectric nanogenerators (TENGs) have gained popularity worldwide as a desired option for harnessing energy. The urgent demand for TENGs is attributed to their novel structural design, low cost, and use of large-scale materials. The output performance of a TENG depends on the surface charge density of the friction layers. Several recycled and biowaste materials have been explored as friction layers to enhance the output performance of TENGs. Natural and oceanic biomaterials have also been investigated as alternatives for improving the performance of TENG devices. Moreover, structural innovations have been made in TENGs to develop highly efficient devices. This review summarizes the recent developments in recycling and biowaste materials for TENG devices. The potential of natural and oceanic biowaste materials is also discussed. Finally, future outlooks for the structural developments in TENG devices are presented.

This study was conducted to investigate whether there were differences in eco-friendly food, home meal replacement (HMR) purchases, and eating-out behavior according to the level of agri-food consumer competence. The data for the study were extracted from main food consumers (n=3,321) in the 2022 Food Consumption Behavior Survey. The competence index was divided into awareness-attitude-practice items, and three groups were classified by competence level. The results showed an agri-food consumer competency score of 70.62, with the highest score for awareness (73.96), followed by practice (69.28) and attitude (66.18). The frequency of purchasing eco-friendly food was higher in the excellent group compared to other groups, and quality and price satisfaction was higher with higher competency (p<0.001). Regarding HMR, the results showed that the shortage group had the lowest HMR consumption rate, and satisfaction decreased as competence decreased (p<0.001). The main reason for eating-out was to enjoy food in all groups (59.0%), followed by a lack of cooking time in the excellent group (15.7%) and hassle with food preparation in the moderate and shortage groups (17.3%, 16.6%) (p<0.001). In short, agri-food consumption competency showed differences by contents and components, and differences in food purchases and eating-out behavior by competency level were found.

As a means to activate eco pastoral system in alpine grassland, the government can consider public pastures, which are currently unused, to scale them up into public ranches. Depending on ownership and operation, four management models proposed as follows: 1) Government-Owned and Operated with Balanced Profit and Loss 2) Government-Owned and Operated with Revenue Generation 3) Government-Owned but Privately Operated by Outsourced to Professional Manager 4) Full Privatization (Ownership and Operation by Private Individuals). The study outlined above proposes four management models for the activation of eco pastoral system in alpine grassland. It also suggests methods for the selection and performance evaluation of manager to establish a profitable structure. Additionally, the research provides management methods for the conservation of grazing ecology in pastoral ecosystems. Particularly, the adaptation of tools commonly used in South Korean business sector for the selection and performance evaluation of manager within the system of the proposed management models. This aspect is deemed valuable as it aligns these tools with the specific characteristics of eco pastoral system in alpine grassland, contributing not only to the effective implementation of the models but also to the enhancement of the revenue structure.
