A Study about Perceptions of Kimono among College Students and Kimono Enthusiasts: Is It Difficult to Move in a Kimono?

Kimono is being reevaluated for its sustainability aspects, such as having fewer offcuts in the production process due to its structural differences from Western-style clothes and its high reusability due to the adaptability to individuals' body shapes. On the other hand, once a common attire for daily wear in Japan, kimono has transitioned to being worn only on special events and the kimono-related industry has also shrunk. To stimulate demand for kimono, it is essential to familiarize younger generations with its potential as daily wear. A questionnaire survey on perceptions of kimono was conducted among two groups in Japan: 211 college students and 50 kimono enthusiasts. The questionnaire included demographic questions and psychometric scales, primarily focusing on their kimono experiences, challenges associated with wearing kimono, their perceptions of kimono and Western-style clothes, and their attitudes towards kimono. The results revealed that a majority of students had worn kimono before, though they found it difficult to move while wearing it. In contrast, kimono enthusiasts evaluated it as easier to move, hard to become disheveled, and casual. They also rated the ease of wearing Western-style clothes lower compared to students, and this tendency intensified with the length of enthusiast experience. Furthermore, the findings indicated that enthusiasts regarded the kimono more as daily wear compared to students, while still deriving enjoyment from it as formal attire in special events. These results suggest that the cognition that Western-style clothes are easy to move and kimono is not may change with experiences. Therefore, providing opportunities for people in Japan to acquire how to wear kimono in comfortable ways possibly impacts their perceptions of kimono.

Assessing Patterns of Continuous Glucose Monitoring Use and Metrics of Glycemic Control in Type 1 Diabetes and Type 2 Diabetes Patients in the Veterans Health Care System: Integrating Continuous Glucose Monitoring Device Data with Electronic Health Records Data.

Objective: To integrate long-term daily continuous glucose monitoring (CGM) device data with electronic health records (EHR) for patients with type 1 and type 2 diabetes (T1D and T2D) in the national Veterans Affairs Healthcare System to assess real-world patterns of CGM use and the reliability of EHR-based CGM information. Research Design and Methods: This observational study used Dexcom CGM device data linked with EHR (from 2015 to 2020) for a large national cohort of patients with diabetes. We tracked the initiation and consistency of CGM use, assessed concordance of CGM use and measures of glucose control between CGM device data and EHR records, and examined results by age, ethnicity, and diabetes type. Results: The time from pharmacy release of CGM to patients to initiation of uploading CGM data to Dexcom servers averaged 3 weeks but demonstrated wide variation among individuals; importantly, this delay decreased markedly over the later years. The average daily wear time of CGM exceeded 22 h over nearly 3 years of follow-up. Patterns of CGM use were generally consistent across age, race/ethnicity groups, and diabetes type. There was strong concordance between EHR-based estimates of CGM use and Dexcom CGM wear time and between estimates of glucose control from both sources. Conclusions: The study demonstrates our ability to reliably integrate CGM devices and EHR data to provide valuable insights into CGM use patterns. The results indicate in the real-world environment that CGM is worn consistently over many years for both patients with T1D and T2D within the Veterans Affairs Healthcare System and is similar across major race/ethnic groups and age-groups.

International trends in daily disposable contact lens prescribing (2000–2023): An update

PurposeDaily disposable contact lenses offer numerous benefits in terms of ocular health and wearer convenience. The purpose of this work is to update earlier surveys by describing global trends in daily disposable lens fitting between 2000 and 2023. MethodAn annual contact lens prescribing survey was sent to eye care practitioners in up to 71 countries between 2000 and 2023, inclusive. Data relating to 265,106 daily wear soft lens fits undertaken in 20 countries returning reliable longitudinal data were analysed in respect of daily disposable lens fitting. ResultsOverall, daily disposable lens prescribing increased over time, from 17.1 % of daily wear soft lens fits in 2000 to 46.7 % in 2023 (p < 0.0001). There were significant differences between countries in daily disposable lens prescribing (p < 0.0001), and between the percentage of males fitted with daily disposable lenses, as a proportion of all daily wear soft lenses (37.2 %), compared to females (35.2 %) (p < 0.0001). Daily disposable lens wearers are slightly younger at fitting than reusable soft lens wearers (31.0 vs 31.2 years, respectively) (p < 0.0001), although this difference is not clinically meaningful. Analysis of 50,240 daily wear soft lenses fitted recently (2019–2023) were found to be prescribed for the following replacement frequencies: daily – 47 %; monthly – 42 %; 1–2 weekly – 9 %; and ≥3 monthly – 2 %. ConclusionThere has been a substantial increase in daily disposable lens fitting throughout the first 24 years of this century. The gradual nature of this increase is commensurate with the staged introduction of daily disposable lens designs and expanded parameter ranges over the survey period.

Normative Values for Daily Functional Recovery Patterns Following Total Knee Arthroplasty

BackgroundWearable devices provide the ability for clinical teams to continuously monitor patients’ rehabilitation progress with objective data. Understanding expected recovery patterns following total knee arthroplasty (TKA) enables prompt identification of patients failing to meet these milestones. The aim of this study was to establish normative values for daily functional recovery in the first 6 weeks after TKA using a wearable device. MethodsThis prospective study included patients who underwent TKA between 2020 and 2023, treated by 11 surgeons from 8 institutions. Eligible participants were aged 18 or older, had a primary unilateral TKA, and owned a smartphone. Knee range of motion, total daily steps, cadence, and device usage were measured continuously over 6 weeks. Statistical analysis included analysis of variance using post hoc Tukey honest significant difference tests. ResultsThe cohort of 566 participants had a mean age of 65 and 69 for men and women, respectively (range, 50 to 80). Women comprised 61% (n = 345) of study participants. There were 82% of women and 90% of men who had a body mass index > 30. The average daily wear time of the device was 12 hours (±4) for a total of 45 days (±27). Recovery was nonlinear, with the greatest gains in the first 3 weeks postsurgery for all metrics. Men demonstrated greater total daily step counts and cadence when compared to women. Obese patients demonstrated poorer performance when compared to lower body mass index patients. ConclusionsTo our knowledge, this study presents the first normative data for tracking daily functional recovery in TKA patients using wearable sensors. Standardizing the TKA recovery timeline allows surgeons to isolate factors affecting patients’ healing processes, accurately counsel them preoperatively, and intervene more promptly postoperatively when rehabilitation is not within standard recovery parameters.

Real-world single center experience with the wearable cardioverter defibrillator: sex differences in risk stratification for sudden cardiac death

Abstract Background Wearable cardioverter defibrillator (WCD) demonstrated an important role for prevention of sudden cardiac death in patients with advanced heart failure and reduced left ventricular ejection fraction. Although in randomized trial there are no gender difference in WCD use and defibrillator (ICD) implantation rate, real world data in female patients is lacking. Purposes: We aimed to describe the sex differences in WCD use, the rate of cardiac events detected with WCD and the rate of ICD implantation after WCD use in women in a real-world single center experience. nd reduced left ventricular ejection fraction or prior ventricular tachyarrhythmia. Methods and results According with the current guidelines indications, between August 2017 and June 2023 ninety-six consecutive patients (mean age 66.0±11.1 years) received a WCD at Piacenza Hospitals and were retrospectively included in this analysis. There were no differences in clinical characteristics between female (18 patients, 18,8%) and male: in particular baseline left ventricular ejection fraction (LV EF) were similar between the two groups (29.5±5.2 vs 27.9±7.9, p=0.23) and no differences were found in the rate of ischaemic cardiopathy (66,6% vs 69,2% p=0.51). After 3-months follow up with WCD use, a similar rate of ventricular arrhythmias were found in the two groups (5.5% vs 3.8%, p=0.48) and no ventricular fibrillation was detected. The WCD usage period and median daily wear time were not different between female and male (55.2±50.6 vs 56.2±34.8 days p=0.53, 21.0±6.4 vs 23.1±1.5 hours p=0.48, respectively). However women presented a better LV EF improvement (12.2±9.7 vs 7.2±6.8, p=0.01), with a significant lower ICD implantation rate at the end of WCD use (55.5% vs 43.8%; p&amp;lt; 0.01) Conclusions In this real word analysis women presented a nice compliance using WCD. In spite of a similar burden of ventricular arrhythmic events, women presented a better LV EF improvement with a significant lower ICD implantation rate.

WEARABLE CARDIOVERTER–DEFIBRILLATORS IN CLINICAL PRACTICE IMPLEMENTATION OF THE ANMCO POSITION PAPER FOR APPROPRIATE USE OF THE WEARABLE CARDIOVERTER DEFIBRILLATOR

Abstract Introduction Wearable cardioverter–defibrillators (WCD) have emerged as a valuable tool in the management of patients at risk for life–threatening arrhythmias. These devices offer a non–invasive and temporary solution, providing continuous monitoring and the potential for prompt defibrillation when needed. In this study, we explore the indications for WCD and evaluate arrhythmic events through comprehensive monitoring. Methods From November 2022 to December 2023, we conducted an outpatient follow–up of 18 patients receiving WCD. Regular check–ups and comprehensive echocardiography were performed to optimize therapy based on specific indications for each patient. Results The average age of the patients was 59.3±17.4 years, with 79% being male. Among the cohort, 58% had hypertension, and a similar percentage comprised smokers and individuals with dyslipidemia, while 32% were diabetic. The indications for receiving WCD were: de novo diagnosis of dilated cardiomyopathy with reduced ejection fraction in 9 (50%) patients, recent acute coronary syndrome and ejection fraction &amp;lt; 35% in 5 (28%), cardiac electronic device infections in 3 (17%) patients and myocarditis with electrical instability in 1 (5%) patient. Patients were in optimal medical therapy (OMT) tailored to their specific comorbidities, with 84% on renin–angiotensin–aldosterone system inhibitors, 95% on beta–blockers, 53% on mineralocorticoid receptor antagonists, 53% on sodium–glucose cotransporter–2 inhibitors, and 37% on antiarrhythmics. The average follow–up was 64±45 days according to specific etiology, with a daily wearing time of 22.9±1.1 hours. No device interventions were recorded. At the end of the follow–up period, 6 (33%) patients still required implantable cardioverter–defibrillator (ICD). Among these, 4 patients (22%) underwent to ICD implantation, 3 for secondary prevention, and 1 for primary prevention, while notably, 2 (11%) patients, declined the procedure. Conclusions The use of wearable cardioverter–defibrillators in the outpatient setting for patients at risk of life–threatening arrhythmias allowed to optimize therapy and restrict the indications for ICD, in our cohort up to 67%, with a good safety profile due to the low incidence of device interventions.

REAL–WORLD SINGLE CENTER EXPERIENCE WITH THE WEARABLE CARDIOVERTER DEFIBRILLATOR: SEX DIFFERENCES IN RISK STRATIFICATION FOR SUDDEN CARDIAC DEATH

Abstract Background Wearable cardioverter defibrillator (WCD) demonstrated an important role for prevention of sudden cardiac death in patients with advanced heart failure and reduced left ventricular ejection fraction. Although in randomized trial there are no gender difference in WCD use and defibrillator (ICD) implantation rate, real world data in female patients is lacking.

Conclusions In this real word analysis women presented a nice compliance using WCD. In spite of a similar burden of ventricular arrhythmic events, women presented a better LV EF improvement with a significant lower ICD implantation rate.

Transtibial osseointegration following unilateral traumatic amputation: An observational study of patients with at least two years follow-up

ImportanceMost patients use a traditional socket prosthesis (TSP) to ambulate independently following transtibial amputation. However, these patients generally require prosthesis repairs more than twice annually and an entirely new prosthesis every two years. Furthermore, transtibial amputation patients have four times the skin ulceration rate of transfemoral patients, prompting more frequent prosthesis refitting and diminished use. Trans-Tibial osseointegration (TTOI) is a promising technique to address the limitations of TSP, but remains understudied with only four cohorts totaling 41 total procedures reported previously. Continued concerns regarding the risk of infection and questions as to functional capacity postoperatively have slowed adoption of TTOI worldwide. ObjectiveThis study reports the changes in mobility, quality of life (QOL), and the safety profile of the largest described cohort of patients with unilateral TTOI following traumatic amputation. DesignRetrospective observational cohort study. The cohort consisted of patients with data outcomes collected before and after osseointegration intervention. SettingA large, tertiary referral, major metropolitan center. ParticipantsTwenty-one skeletally mature adults who had failed socket prosthesis rehabilitation, with at least two years of post-osseointegration follow-up. Main outcomes and measuresMobility was evaluated by K-level, Timed Up and Go (TUG), and Six Minute Walk Test (6MWT). QOL was assessed by survey: daily prosthesis wear hours, prosthesis problem experience, general contentment with prosthesis, and Short Form 36 (SF36). Adverse events included any relevant unplanned surgery such as for infection, fracture, implant loosening, or implant failure. ResultsAll patients demonstrated statistically significant improvement post osseointegration surgery with respect to K-level, TUG, 6MWT, prosthesis wear hours, prosthesis problem experience, general prosthesis contentment score, and SF36 Physical Component Score (p < 0.01 for all). Three patients had four unplanned surgeries: two soft tissue refashionings, and one soft tissue debridement followed eventually by implant removal. No deaths, postoperative systemic complications, more proximal amputations, or periprosthetic fractures occurred. Conclusions and relevanceTTOI is likely to confer mobility and QOL improvements to patients dissatisfied with TSP rehabilitation following unilateral traumatic transtibial amputation. Adverse events are relatively infrequent and not further disabling. Judicious use of TTOI seems reasonable for properly selected patients. Level of evidence2 (Therapeutic investigation, Observational study with dramatic effect).

Evaluation of mucin changes between daily and extended wear silicone hydrogel contact lenses

Background: Initially, contact lenses were recommended only for daily wear because of infection and discomfort concerns. With rising demand, particularly for overnight use, extended wear lenses have gained significance. Despite concerns, intensive development of materials like Lotrafilcon B aims to meet this demand, focusing on comfort and safety.Aim: This study aimed to evaluate the mucin quantity and quality changes between daily and extended wear (Lotrafilcon B), impacting eye health and comfort.Setting: The study was conducted at Kirana Eye Center, Cipto Mangunkusumo Hospital, Jakarta, Indonesia.Methods: This study was a single-blinded randomised clinical trial with two parallel groups. Forty (40) eligible subjects willingly participated. Mucin 5AC (MUC5AC) and Ferning-type tests were conducted. The 40 subjects with moderate myopia were then divided into a daily wear and an extended wear group. The MUC5AC test was performed at pre-fitting and at 4 weeks, whereas the Ferning-type tests were taken at pre-fitting and 1st and 4th weeks.Results: For both groups, there was a significant increase in MUC5AC levels from pre-fitting to week four, but with no significant difference between them in final MUC5AC levels. Additionally, the comparison of eyes with normal and abnormal Ferning-types between the two groups showed no significant differences at pre-fitting, 1st and 4th weeks.Conclusion: There is no significant difference in MUC5AC levels with the use of daily or extended wear (with Lotrafilcon B).Contribution: This study compares the impact of daily and extended wear Lotrafilcon B contact lenses on eye health and comfort in moderate myopia patients.

Large‐Scale Flexible Fabric Biosensor for Long‐Term Monitoring of Sweat Lactate

AbstractIntegrating sweat biosensors into daily wear has the potential to effectively monitor personal lactate levels, offering the advantages of convenience, precision, and multi‐point detection. However, existing wearable fabric sweat biosensors have limitations in terms of long‐term repeatable detection and washability due to the difficulty of building a stable layer of recognition materials on the highly curved fiber surface. Here, a long‐term repeatable and washable electrochemical fabric biosensor is reported based on a fiber electrode with multi‐scaled aligned channels for efficient and reliable lactate detection. Through the functionalization of a molecularly imprinted polymer with redox‐sensitive nano reporters, the fabric biosensor exhibits impressive in situ long‐term repeatable detection for more than 400 times, washability, and stability under deformations. The multi‐scaled channels contribute to a desired electric field distribution and thus a reliable interface between the polymer and the fiber. Employing industrial sewing technology, a 20 m (L) × 0.5 m (W) sensing fabric is further produced. Ultimately, combined with a wireless communication element, the fabric biosensing system can immediately track lactate levels.

Pediatric Hearing Aid Daily Wear Time Is Significantly Impacted by Clinician-Family Language Discordance.

The purpose of this study was to evaluate the potential contribution of limited English proficiency on daily hearing aid wear time for children with hearing loss. A retrospective chart review was completed to evaluate hearing aid wear time based on data logging information available at the time of a follow-up visit following an initial hearing aid fitting. Children were included in the study if they had permanent bilateral hearing loss and were less than 60 months of age at the time of their first follow-up visit. Wear time was compared between children who attended an interpreter-mediated appointment and those who did not have an interpreter present. The presence of an interpreter at the appointment was the study indicator that the family had limited English proficiency. Children from families with limited English proficiency exhibited significantly shorter daily wear time (M = 1.3 hr) than their peers whose families were English-proficient speakers, thus, having a shared language with their audiologists (M = 5.2 hr). Results of this study suggest that family-clinician language discordance might put children at greater risk of shorter hearing aid wear time than children whose caregivers share a common language with their child's audiologist. There can be many linguistic, cultural, and educational factors that contribute to hearing aid wear time in children whose families have limited English proficiency as well as different approaches to improving that wear time. Efforts should ensure that hearing and hearing aid-related information is accessible to all families, especially those with clinician-family language discordance. Such efforts can include, among others, training that improves clinicians' cultural and linguistic responsiveness to the diverse families they serve.

Analysis of Surgical Masks Adverse Effects on Facial Skin in Long Term Usage During COVID-19 Pandemic.

During the coronavirus disease-2019 pandemic, masks have become mandatory for protection against the virus transmitted by breathing. This study examined the impact of surgical masks used daily on civilian facial skin. Moisture, elasticity, pore, melanin, acne, wrinkle, and sensitivity parameters of 83 volunteers were measured numerically using an API-100 skin analyzer and camera recordings. Numerical values were compared following the device's algorithm calibrated according to age, gender, and race. Finally, the obtained data were statistically evaluated and compared with the averages. Pore, melanin, acne, and wrinkle parameters were higher without gender discrimination, whereas moisture and elasticity parameters were low. While a significant increase was observed in women for sensitivity, the increase was not statistically significant in men. The negative effects of long-term daily wearing of surgical masks on facial skin were statistically significant. Therefore, taking outdoor breaks during mask use, washing the face intermittently, using moisturizing and purifying cosmetic products, and anti-wrinkle effects have been proposed to reduce the possible defects.

Study on the fit testing for the workers wearing hearing protection device in machinery manufacturing enterprises

Objective: To investigate the occupational noise hazards in five machinery manufacturing enterprises, and to evaluate the individual noise reduction values and influencing factors of workers wearing hearing protection device (HPD) by individual fit testing. Methods: From November 2021 to January 2022, 5 machinery manufacturing enterprises in Bao'an District of Shenzhen were selected to conduct an occupational health survey to understand the noise exposure level of workers. The 3MTM E-A-RfitTM fitness test system was used to test the baseline individual sound attenuation value level (PAR) of the daily wear of the ear protecters for 485 workers in typical noise working positions. Workers whose PAR values could not meet the requirements of noise reduction at work were instructed to wear and repeated tests were conducted. PAR results of the workers before and after the intervention were collected and analyzed. Results: The noise workers who received the suitability test were mainly distributed in 24 types of work, the job noise exposure level was 80.2 dB (A) ~ 95.0 dB (A), and the job noise excess rate was 52.5% (138/263). The median baseline PAR [M (Q(1), Q(3)) ] for 485 workers was 6.0 (0.0, 14.0) dB. The baseline PAR of male workers, those with more than 15 years of working experience, those with more than 15 years of using ear guards, those who considered ear guards comfortable to wear, those with college degree or above, and those exposed to noise level 90 dB (A) were higher, and the difference was statistically significant (P<0.05). A total of 275 workers (56.7%) did not pass the baseline PAR test, and there was no statistically significant difference in the intervention rate of workers in different noise groups (P>0.05). PAR in subjects who did not pass baseline after intervention increased from 0.0 (0.0, 3.0) dB to 15.0 (12.0, 18.2) dB. Conclusion: The workplace noise hazard of machinery manufacturing enterprises is serious, and there is a great difference between the baseline PAR and the nominal value of the hearing guard worn by the noise exposed workers. The intervention measures can effectively improve the protective effect of wearing ear protectors.

Multifocal contact lens success predictability

PurposeThe current multi-study analysis combined data from three studies to quantify the relationship between the initial reaction to soft multifocal contact lens (MFCL) design types at dispensing and evaluate the predictability of overall vision satisfaction (OVS) and intention to purchase (ITP) after 1 week of wear. MethodThree prospective studies tested MFCLs over 1-week of wear following the same protocol, using a range of potentially predictive ratings at dispensing, and both OVS and ITP at 1-week as an indicator acceptance level. In each study, two of MyDay® multifocal, clariti® 1 day multifocal, Biofinity® multifocal (worn as a daily disposable lens) or 1 DAY ACUVUE® MOIST MULTIFOCAL were dispensed for 1-week of daily wear. OVS was recorded on a 100-point VAS and ITP on a 5-point LIKERT scale. Fourteen possible predictors were entered in the statistical model, and predictability was assessed using Chi-square Automatic Interaction Detector (CHAID) statistical test. ResultsA total of 210 participants (152 female & 58 male; 53.9 ± 6.5 years, range 41–71 years), representing 420 MFCL fits, equally distributed between emergent n = 65, established n = 70 and advanced n = 75 presbyopes, completed the studies. OVS on dispensing was the predictor of both OVS (p < 0.001) and ITP (p < 0.001) at 1-week. For OVS predictability, 70.8 % with OVS at dispensing > 91 points reported good OVS at 1-week and 73.4 % with OVS on dispensing ≤ 80 points reported poor OVS at 1-week. For ITP predictability, 74.6 % with OVS at dispensing > 94 points reported a positive ITP at 1-week and 65.9 % with OVS on dispensing ≤ 63 points reported negative ITP at 1-week. ConclusionOverall vision satisfaction at the time of dispensing MFCLs is a powerful indicator of both OVS and ITP after 1-week of wear. Initial patient subjective assessments provide a clinically useful indicator of the likeliness of success.

Diagnostic Dilemma in Differentiating Odontogenic Pain and Non Odontogenic Pain: A Case Series

Pain is one of the most common reasons why patients seek medical attention. When experiencing discomfort in the orofacial region, a dentist is usually the first medical professional consulted. While odontogenic factors are the most common causes of acute pain in the maxillofacial region, it can also be non odontogenic, making it challenging to differentiate between the two. However, with a thorough examination, taking a complete history, and ordering necessary diagnostic tests, a dentist can make an accurate diagnosis and evaluate the entire stomatognathic system and other relevant anatomical regions. Misdiagnosis can lead to unnecessary dental procedures and cause trauma to the patients. Case 1 (50-year-old female) and case 3 (63-year-old female) were finally diagnosed as Trigeminal Neuralgia (TN), which were initially misdiagnosed as odontogenic pain and were treated with unnecessary irreversible dental treatments like Randomised Controlled Clinical Trials (RCT). Case 2 ( 28-year-old female) was eventually diagnosed as a case of myofascial pain with loss of muscle tone, for which the patient required palliative physical therapy. Instead, the splint, which was worn day and night by the patient, and soft diet resulted in muscle atrophy. The present case series emphasises the importance of accurate diagnosis to prevent irreversible dental treatment and protect patients from harm.

Smart Home Sleep Respiratory Monitoring System Based on a Breath-Responsive Covalent Organic Framework.

A smart home sleep respiratory monitoring system based on a breath-responsive covalent organic framework (COF) was developed and utilized to monitor the sleep respiratory behavior of real sleep apnea patients in this work. The capacitance of the interdigital electrode chip coated with COFTPDA-TFPy exhibits thousands-level reversible responses to breath humidity gases, with subsecond response time and robustness against environmental humidity. A miniaturized printed circuit board, an open-face-mask-based respiratory sensor, and a smartphone app were constructed for the wearable wireless smart home sleep respiratory monitoring system. Leveraging the sensitive and rapid reversible response of COFs, the COF-based respiratory monitoring system can effectively record normal breath, rapid breath, and breath apnea, enabling over a thousand cycles of hour-level continuous monitoring during daily wear. Next, we took the groundbreaking step of advancing the humidity sensor to the clinical trial stage. In clinical experiments on real sleep apnea patients, the COF-based respiratory monitoring system successfully recorded hour-level sleep respiratory data and differentiated the breathing behavior characteristics and severity of sleep apnea patients and subjects with normal sleep function and primary snoring patients. This work successfully advanced humidity sensors into clinical research for real patients and demonstrated the enormous application potential of COF materials in clinical diagnosis.

A stretchable wearable sensor with dual working electrodes for reliable detection of uric acid in sweat

Wearable sweat sensors with stretch capabilities and robust performances are desired for continuous monitoring of human health, and it remains a challenge for sweat sensors to detect targets reliably in both static and dynamic states. Herein, a flexible sweat sensor was created using a cost-effective approach involving the utilization of three-dimensional graphene foam and polydimethylsiloxane (PDMS). The flexible electrochemical sensor was fabricated based on PDMS and Pt/Pd nanoparticles modified 3D graphene foam for the detection of uric acid in sweat. Pt/Pd nanoparticles were electrodeposited on the graphene foam to markedly enhance the electrocatalytic activity for uric acid detection. The graphene foam with excellent electrical property and high porosity, and PDMS with an ideal mechanical property endow the sensing device with high stretchability (tolerable strain up to 110 %), high sensitivity (0.87 μA μM−1 cm−2), and stability (remaining unchanged for more than 5000 cycles) for daily wear. To eliminate possible interferences, the wearable sensor was designed with dual working electrodes, and their response difference ensured reliable and accurate detection of targets. This strategy of constructing sweat sensors with dual working electrodes based on the flexible composite material represents a promising way for the development of robust wearable sensing devices.

Pocketable and Smart Electrohydrodynamic Pump for Clothes.

Seamlessly fusing fashion and functionality can redefine wearable technology and enhance the quality of life. We propose a pocketable and smart electrohydrodynamic pump (PSEP) with self-sensing capability for wearable thermal controls.

STUDY OF CONSUMER PREFERENCES TO SUPPORT THE MARKETING STRATEGY OF THE THRIFT CLOTHING BUSINESS

With the increasing number of thrift shops and traditional markets on Lombok Island, researchers view research in relation to consumer behavior and marketing strategies as very important. The purpose of this study is to analyze consumer preferences as a supporter of the marketing strategy of the thrift clothing business on Lombok Island. In-depth interviews were conducted with five key informants of this study who are business people and consumers of thrift clothing who have shopped at least five times at markets or thrift stores on Lombok Island. The results of this study show that thrift clothing consumers mostly make purchases offline of daily wear and clothing to work. In addition, consumers buy thrift clothes because of the availability of various brands from various countries such as Korea, Japan, and America. The reason for consumer preference in purchasing thrift clothing is because of the much cheaper price, much better quality of materials, the availability of various unique models to meet the needs of consumer fashion styles, and a little awareness of environmental sustainability. The result of this study provides an overview of consumer preference patterns that can be used in the preparation of marketing strategies, namely in terms of price, products, and distribution channels. Theoretically, the results of this study also enrich the wealth of knowledge in the field of consumer behavior, especially regarding consumer preferences in purchasing used clothes.
