People have struggled with many infectious diseases throughout history. Today, the Covid-19 is being fought. One of the most important things for people who have or are at risk of getting Covid-19 is social isolation. Many countries resort to different ways to ensure social isolation. For this, remote patient monitoring systems have been developed. In this study, the problem of the selection of Covid-19 remote patient monitoring systems is discussed. Seven Wearable Health Technology (WHT) products were evaluated with a total of 10 criteria, including the important symptoms used in the patient tracking systems. The weights of 10 criteria determined by the Analytical Hierarchy Process (AHP) method were calculated, and these weights were used in the solution of The Preference Ranking Organization Method for Enrichment Evaluation (PROMETHEE), and Technique for Order Preference by Similarity to Ideal Solutions (TOPSIS) methods. WHT products were compared. As a result, the most appropriate patient follow-up system was determined. This study generates differences in terms of evaluating seven different products and ten criteria in total with MCDM methods. A more comprehensive evaluation has been made in the literature than the studies in this field.

This study investigated the application research of aerogel materials in clothing and analyzed the current research focus on aerogel clothing, the details of the development of aerogel materials, and the evaluation of the application effects of aerogel in clothing. Current research mainly focuses on the application of aerogel in firefighting clothing, space suits, wetsuits, and footwear products. The aerogel materials used in surveyed studies can be classified into aerogel fiber composite, aerogel foam composite, and aerogel coating fabric. Aerogel fiber composite is the most widely used aerogel material in the clothing industry. The thermal performance, mechanical properties, and comfort performance of aerogel clothing have been qualitatively discussed. This survey revealed that aerogel positively affects thermal performance of clothing. In addition, the mechanical properties such as the durability and strength of aerogel materials can meet the application requirements of clothing. However, the dust contamination hazard of aerogel particles limits the further application of aerogels in clothing. In addition, the experimental evaluation of the comfort performance of aerogel clothing through human- and manikin-wearing experiments is insufficient. The findings of this study reveal that it is essential to conduct further studies on the comfort performance of aerogel clothing to determine whether aerogel can have widespread application in clothing. Lastly, we provide suggestions on directions for future studies on the application of aerogels in clothing.

To prepare measures for washing synthetic fibers, which cause proliferation of microplastics in the marine ecosystem, a fundamental analysis is required. Therefore, this study established an efficient method for quantitatively analyzing microfibers using artificial neural networks, comparing the amounts of microfibers generated in the manufacturing, wearing, and washing processes of clothing. The proportion of microfiber emitted during the manufacturing process was the largest (49%), followed by that emitted during the washing (28%) and wearing (23%) processes. This suggests that minimizing the amount of microfiber emitted during the manufacturing process is key to solving microfiber issues in the fashion industry. Additionally, during the wearing process, the amount of waterborne microfiber detected in washing was slightly larger than the amount of airborne microfiber. In the washing process, the washing temperature did not significantly affect microfiber emissions. However, when reducing the amount of water used or increasing the number of washings, microfiber emissions increased noticeably due to the greater friction applied to clothes. A common result of all experiments was that the largest proportion of microfibers was released during the first five washing cycles. Therefore, before wearing new items, consumers can minimize microfiber release by pre-washing using a laundry bag that filters microfibers. Furthermore, the most effective way to minimize microfibers is to eliminate them from the manufacturing process before they are distributed to consumers.

This study aimed to ascertain the appropriate test methods for the investigation of the effect of personal protective equipment on mobility of firefighters. Nine male volunteers performed a physical performance test (crawl, obstacle course, side-to-side jumps, heavy-object drag, and step-ups), functional balance test (functional reach, timed up and go, and wooden plank time), range of motion test, and subjective evaluation under four clothing conditions with different weights and combinations of personal protective equipment. The results showed that physical performance, functional balance ability, and joint angles significantly declined with increased weight of personal protective equipment. On subjective evaluation, wearing heavy personal protective equipment increased perceived exertion and discomfort on movement. Our results proved that some of our test methods, including the obstacle course, side-to-side jumps, functional reach, timed up and go, range of motion test, and subjective evaluation, can be used to examine the mobility of personal protective equipment wearers. The findings of this study provide an effective guide for researchers and firefighters regarding the evaluation of mobility with personal protective equipment, as well as for manufacturers in the development of enhanced, comfortable personal protective equipment.

This study proposes an advanced algorithm for predicting the optimal orientation in human manikin 3D printing. We can print the manikin mesh data on any scale depending on the user’s needs. Once the 3D printing scale was determined, the manikin data were dissected based on the 3D printer’s maximal printing volume using our previous work. Then, we applied the newly proposed algorithm, designated as “per-pixel signed-shadow casting,” to each dissected manikin part to calculate the volumes of the object and the support structure. Our method classified the original mesh triangles into three groups—alpha, beta, and top-covering—to eliminate the need for special hardware such as graphic cards. The result is shown as a two-dimensional bitmap file, designated as “tomograph”. This tomograph represents the local support structure distribution information on a visual and quantitative basis. Repeating this tomography method for the three rotational axes resulted in a four-dimensional (4D) box-shaped graph. The optimal orientation of any arbitrary object is easily determined from the lowest-valued pixel in the 4D box graph. We applied this proposed method to several basic primitive shapes with different degrees of symmetry and complex shapes, such as the famous “Stanford Bunny”. Finally, the algorithm was applied to human manikins using several printing scales. The theoretical values were compared with those obtained from analytical or g-code-based experimental volumes.

With technological advances in wearable health care monitoring system, there increasing demands for the patterning technology for reliable sensors. Dry-film photoresists (DFRs) have several advantages for the patterning of silver nanowires (AgNWs), including cost-effectiveness, low toxicity of the process, and ease of mass production through a roll-to-roll process. In this study, using DFRs, we achieved the facile fabrication of AgNW-based chips for optical detection of myoglobin (Mb) via surface-enhanced Raman spectroscopy (SERS). Mb is found in accessible biological fluids such as urine and serum, which is a representative protein biomarker for human health monitoring. AgNWs were successfully patterned on polyethylene terephthalate films using DFR to form multiple spots, with a diameter of ~500 µm, that are available for detection. SERS spectra showed that the AgNW chips can efficiently detect myoglobin proteins down to levels of clinical significance. Our results will provide insights for the cost-effective production method of futuristic health care monitoring system.

As a part of material culture, clothing embodies the cultural specificity based on the influence of that culture on individuals. The cultural value model of Hofstede broadly describes the dimensional characteristics of each country. At the same time, the proximity of clothing to a self-scale represents the level of psychological closeness of clothing to identity. Even though it is theoretically correct that these two concepts—culture and clothing that expresses one’s self—are related, few studies have highlighted this connection. In this study, we investigated the effect of cultural values on how the individuals involve their clothing with their social identity by focussing on the differences between two culturally different countries: South Korea and Mongolia. Quantitative surveys from 179 in South Korea and 262 in Mongolia and t-tests showed cultural differences in both countries’ individualism and indulgence vs their restrained disposition. The multiple regression analysis results revealed that uncertainty avoidance and indulgence correlate with three dimensions in the proximity of clothing to self: clothing to self as structure, clothing as a response to others’ judgements, and clothing-related to self-esteem. The moderating effect of each country was not found. This result implies that knowing the cultural values of a particular group can infer their clothing consciousness. Thus, when fashion companies target millennial women in South Korea and Mongolia and establish a more significant presence abroad, examining a country’s or a group’s culture helps identify the target market's clothing perceptions.

This study investigated how film franchise fans with varying levels of fanship perceive subtle versus explicit signals featured on fan-themed apparel products. A between-subjects experimental design was conducted with two fan-themed t-shirt designs (explicit vs. subtle) × fanship (low vs. high). In this study, the joint effect between subtle vs. explicit designs and fanship was examined to address perceived differentiation, social connection, and purchase intention. For perceived differentiation and social connection, fans with high fanship perceived the subtle design to be more effective than explicit designs. While fans with low fanship perceived the subtle design to be more effective for differentiation, they perceived that the explicit design facilitated social connection more than the subtle design. When fans perceived that signals featured on fan-themed apparel products differentiated themselves from others and facilitated social connection, their purchase intentions increased. The study yielded several theoretical and practical implications. First, the study contributed to the literature on signaling theory, extending the definition of subtle signals to include a more diverse range of design details, such as the content of graphics rather than the visibility and size of brand logos. The study also extended the use of signaling theory and optimal distinctiveness theory to new research areas of fan-themed products. Second, practical implications for producers, marketers, and retailers of fan-themed apparel included the consideration of developing fan-themed apparel with subtle signals, co-creating products with fans, and targeting female fans through more inclusive merchandising practices.

Effect of hair conditioner formulated with Argan oil or Camellia oil was investigated on the protection of hair damaged by bleaching. Six different rinse-off type hair conditioners were made with the basic ingredients of hair conditioner and one of the following conditioning agent; Argan oil (AO), Camellia oil (CO), Palmitic acid (PA), Stearic acid (SA), Oleic acid (OA), and Linoleic acid (LA). L*, a*, b* color values and tensile strength, elongation were measured, and the amount of protein leak was examined using the Bradford Protein Assay. Statistical significance was tested using the SPSS statistical software. Although both AO and CO were effective in protecting the tensile properties of bleached hair, significant effects were observed with AO in enhancing the tensile strength and retaining the color of bleached hair. This might be due possibly to the difference in the composition of four major fatty acids in Argan oil and Camellia oil.

Commercially available children’s cloth masks range widely in material type and fabric structures, methods of construction, layering, and shape, and there is a lack of sizing systems, anthropometric data or guidelines specifically targeting the fit assessment and design of cloth face masks for children 4-6 years old. To better identify and understand the cloth face mask fit and functional needs of children ages 4-6 years old, the researchers embarked on interdisciplinary in-depth study to investigate commercial market offerings of children’s face masks, identify consumer perspectives, and explore mask design improvements through design research. By triangulating results from survey feedback, commercial market content analysis, and wear trial observations, the researchers were able to identify important design criteria that can be used in the improvement of children’s cloth face mask design: size, comfort, dexterity, movement, and thermal comfort. These criteria were used to iteratively develop new mask prototypes involving a 3D printed head form, traditional sewing and hand patternmaking skills, and the creation of multiple mask versions to explore the design criteria listed above. The designs were interpreted through Bye’s (2010) Problem-Based Design Research (PBDR) framework, which identifies common design research practices in the field on a spectrum and situates PBDR as a process centered on a problem as impetus for design through which artifacts are developed.
