Human–Object Interaction: Development of a Usability Index for Product Design Using a Hierarchical Fuzzy Axiomatic Design

Consumer product usability has been addressed using tools that evaluate objects to improve user interaction. However, such diversity in approach makes it challenging to select a method for the type of product being assessed. This article compiles the concepts used since the origin of usability in product design. It groups them by attributes to formulate a usability index proposal. Due to the nature of the data, fuzzy, hierarchical, and axiomatic tools were applied to a trial group of experts and users. Three questionnaires were designed and administered throughout a five-stage process to collect and select attributes, rank them in importance, assign fuzzy values, obtain their numerical representation of use, and assign a qualitative category. By analyzing a case study, this research demonstrates the value of the index by comparing the use of computer mice. Unlike other approaches to evaluating usability, the proposed index incorporates the hierarchical importance of attributes. It allows for participants to express their opinions, transforming subjective responses into linguistic values represented in triangular areas, resulting in a more accurate representation of reality. Additionally, the complexity of the human–object interaction is treated by an information axiom to compute the usability index on a scale from 0 to 1, which reflects the probability of the product meeting the desired usability attributes.

Effectiveness of dairy products to protect against cognitive decline in later life: a narrative review.

As the world's population ages the prevalence of age-related health concerns is increasing, including neurodegeneration disorders such as mild cognitive impairment, vascular dementia and Alzheimer's disease. Diet is a key modifiable risk factor for the development of neurodegeneration, likely due to gut-brain axis interactions related to neuroinflammation. Analyses of dietary patterns identified dairy as being part of a cognitively healthy diet; however, its contribution to cognitive outcomes is difficult to discern. This narrative review evaluates the literature to determine whether there is sufficient evidence that the consumption of dairy products helps to maintain cognitive function in later life. A search using the terms (dairy OR milk OR cheese OR yogurt OR yogurt) AND ("mild cognitive impairment" OR dementia OR "Alzheimer's disease") identified 796 articles. After screening and sorting, 23 observational studies and 6 intervention studies were identified. The results of the observational studies implied that the relationship between total dairy consumption and cognitive outcomes is inverse U-shaped, with moderate consumption (1-2 servings per day) being the most beneficial. The analysis of the intake of different types of dairy products indicated that fermented products, particularly cheese, were most likely responsible for the observed benefits. The experimental studies all used dairy-derived peptides produced during fermentation as the dietary intervention, and the results indicated that these could be an effective treatment for early-stage cognitive impairment. Further experimental studies with whole dairy products, particularly fermented dairy, are needed to determine whether the regular consumption of these foods should be recommended to maximize the likelihood of healthy cognitive aging.

TINJAUAN HUKUM ISLAM TERHADAP JUAL BELI BARANG MYSTERI BOX DI MARKET PLACE SHOPEE

The mystery box business involves buying and selling online. The items sold in mystery box products vary. In general, this purchase implies a surprising thought, so that the buyer in particular is not aware of the contents of the mystery box, but can only determine the type of product. Shopee is a platform that sells mystery box products and is currently popular among the public. Different from ordinary buying and selling, this buying and selling arouses the interest of buyers because this business is considered truly unique and profitable, but many buyers still regret it and feel they have been disadvantaged. This is because the seller does not declare the goods inside and therefore the goods received cannot be returned. In this research, the problem formulation is how the concept and practice of mystery box buying and selling transactions sold on Shopee and how mystery box buying and selling transactions on Shopee are reviewed from Islamic law. The author uses descriptive analysis research methods with actions based on quality. Data was collected through literature study. The research results show that the law of buying and selling mystery boxes is haram, because the buying and selling of mystery boxes on Shopee is effectively canceled based on the terms of the Ba'i Salam Agreement because one of the Ba'i Salam conditions, namely the privileges and types of goods, are not met. And such transactions are also included in buying and selling gharar.

Comparison of mechanical strengths and microstructure of Portland cement-calcium sulfoaluminate cement binders with cellulose ethers of different viscosities

Portland cement-calcium sulfoaluminate cement (PC-CSA) binders possess special characteristics that are obviously different from that of a single component. This will affect the modification effect of cellulose ethers with different viscosities on cement. This study focuses on the mechanical properties, hydration process, type and content of hydration products, pore structure and interface structure of the binders with cellulose ethers, i.e. hydroxyethyl methyl cellulose (HEMC). The following results have been obtained that adding high content of CSA can improve the early mechanical strengths of the binders, while high content of PC is beneficial to the maintenance of the strengths at the middle and late stages. Compared with low viscosity HEMC, high viscosity HEMC reduces the mechanical strengths. Based on the hydration heat evolution results, high content of CSA significantly promotes the early hydration heat release of the binders. When the PC content is 85 %, adding high viscosity HEMC delays the hydration of the binders, but the hydration is promoted when the PC content is 50 %. Combined with the XRD and TG-DTG tests, the content of typical AFt and Al(OH)3 hydration product is relatively high in the binders with high content CSA. AFm has generated in the binders at mid-late age and adding HEMC improves its formation. Adding HEMC delays the formation of CH, while the HEMC viscosity has a limited effect. According to MIP results, the pore content in the binders tends to increase with the CSA content. The incorporation of HEMC significantly increases the pore content of all sizes, especially macro pores. And the greater the HEMC viscosity, the more obvious the above effect. The nanoindentation test results show that incorporating HEMC decreases the elastic modulus of the binders and weakens the interface structure between cement pastes and sands.

My feed is what I eat? A qualitative study on adolescents' awareness and appreciation of food marketing on social media

AbstractBackgroundAdolescents spend much of their time online and hence are exposed to a lot of non‐core (energy‐dense, nutrient‐poor) social media food marketing (SMFM). This may influence their dietary choices and health. This present study aimed to investigate adolescents’ perceptions towards SMFM; that is, their recognition and appreciation of SMFM.MethodsSemi‐structured one‐on‐one interviews were conducted with Dutch adolescents aged 13–16 years (n = 16), on Skype. Examples of food promotions on Instagram, Snapchat, TikTok and YouTube were discussed with adolescents.ResultsAdolescents’ reasons for recognising and appreciating or liking SMFM were often related to the level of product integration. Factors that determined participants’ recognition of SMFM included product focus (e.g., brand or product prominence), sponsorship disclosure, type of content (paid, influencer and peer‐generated content) and promotional strategy (e.g., discounts, promotional texts, layout). Participants’ appreciation of SMFM was determined by the format of a post (image, video, text, pop‐up), trustworthiness of the source (brand, celebrity, friend/peer), type of product promoted (core, non‐core) and appearance or layout of a post (e.g., professionalism, appeal).ConclusionsThe present study contributes to the ongoing debate on how to increase adolescents’ resilience to commercial messages that promote non‐core foods. Adolescents mostly enjoy watching non‐core video content from peers or influencers and do not perceive this as food marketing. It is recommended that future studies investigate the effects of earned social media marketing formats (i.e., unpaid peer and influencer endorsements) promoting non‐core foods on adolescents’ dietary intake, and how they can be made more critical towards such types of SMFM.

Ozone treatment of meat and meat products: a review

Ozone treatment is a non-thermal method for disinfection; ozone is a powerful oxidizing agent that has been shown to be effective in reducing microbial load, extending the shelf life of meat products. This mini-review covers the analysis of the antimicrobial ozone activity in different meats (beef, poultry, pork, seafood, etc.), emphasizing the ozone application methods (liquid or gaseous phase), the applied concentrations and contact times and the effects of ozone treatment on meat quality, safety, and sensory properties. It has been demonstrated that ozone is effective against a broad range of microorganisms, including both Gram-positive and Gram-negative bacteria, spores, and vegetative cells. The efficacy of ozone depends on various factors, such as concentration, type of treatment, temperature, and presence of organic material. Ozone treatment, known for its rapid decomposition and lack of residue, provides an environmentally friendly alternative to traditional chemical sanitizers. Ozone treatments exhibit promising results in enhancing the safety and extending the shelf life of meat products. According to the findings, the application of ozone is an effective technology for prolonging the shelf life of different types of meats and meat products, requiring careful establishment of conditions on a case-by-case basis.

Platelet transfusions in adult ICU patients with thrombocytopenia: A sub-study of the PLOT-ICU inception cohort study.

Platelet transfusions are frequently used in the intensive care unit (ICU), but current practices including used product types, volumes, doses and effects are unknown. Sub-study of the inception cohort study 'Thrombocytopenia and Platelet Transfusions in the ICU (PLOT-ICU)', including acutely admitted, adult ICU patients with thrombocytopenia (platelet count <150 × 109/L). The primary outcome was the number of patients receiving platelet transfusion in ICU by product type. Secondary outcomes included platelet transfusion details, platelet increments, bleeding, other transfusions and mortality. Amongst 504 patients with thrombocytopenia from 43 hospitals in 10 countries in Europe and the United States, 20.8% received 565 platelet transfusions; 61.0% received pooled products, 21.9% received apheresis products and 17.1% received both with a median of 2 (interquartile range 1-4) days from admission to first transfusion. The median volume per transfusion was 253 mL (180-308 mL) and pooled products accounted for 59.1% of transfusions, however, this varied across countries. Most centres (73.8%) used fixed dosing (medians ranging from 2.0 to 3.5 × 1011 platelets/transfusion) whilst some (mainly in France) used weight-based dosing (ranging from 0.5 to 0.7 × 1011 platelets per 10 kg body weight). The median platelet count increment for a single prophylactic platelet transfusion was 2 (-1 to 8) × 109/L. Outcomes of patients with thrombocytopenia who did and did not receive platelet transfusions varied. Among acutely admitted, adult ICU patients with thrombocytopenia, 20.8% received platelet transfusions in ICU of whom most received pooled products, but considerable variation was observed in product type, volumes and doses across countries. Prophylactic platelet transfusions were associated with limited increases in platelet counts.

Harm perceptions across vaping product features: An on-line cross-sectional survey of adults who smoke and/or vape in the United Kingdom.

Vaping products are diverse with a wide variety of features, and popular products change rapidly. This study examined the features and types of vaping products that people who smoke and/or vape perceive contribute to the health harms of vaping. This was a cross-sectional survey co-designed with adults who smoked/vaped and pre-registered. An on-line survey (November 2022) was used of a convenience sample of adults in the United Kingdom who smoked and/or vaped (n = 494). As primary outcomes, respondents were asked to select any of 15 vaping product features they perceived might have any effect on the health harms of vaping (for each: selected, not selected). Independent variables were smoking/vaping status (smoke and vape; vape, formerly smoked; vape, never regularly smoked; smoke, do not currently vape); relative vaping harm perceptions [less harmful than smoking (accurate), equally/more harmful than smoking or do not know/refused (other)]. Binary logistic regressions were used to compare outcomes by current vaping/smoking status and relative harm perceptions, adjusting for age and sex. Most people (54.7%) selected between one and three features. The most frequently selected were nicotine concentration (62.2%) and amount of e-liquid consumed (59.1%), followed by nicotine type (e.g. salt or freebase; 33.0%), source/purchase location (25.3%), flavours (24.7%), temperature to heat e-liquid (21.1%), heat produced by device (20.9%), e-liquid brand (20.9%), amount of emissions (18.6%), device type (e.g. disposable, pod, tank; 17.2%), material of tank (17.0%), power/wattage (13.0%), device brand (8.1%), device size (4.1%) and device weight (2.4%). Higher nicotine concentrations, more e-liquid and salt (versus freebase) nicotine were perceived to confer greater harms. Disposables were perceived as slightly more harmful than reusable devices. There were few differences by current vaping/smoking status and between those with accurate (versus other) harm perceptions of vaping relative to smoking (P > 0.05 for most contrasts, adjusting for age and sex). Certain features and types of vaping products [higher nicotine concentrations, more e-liquid consumed and salt (versus freebase) nicotine]were perceived to confer greater health harms among a sample of UK adults who smoked and/or vaped. Findings are consistent with pervasive misperceptions that nicotine is a major cause of harm, although e-liquid volume is likely to contribute to harms.

Advice to People with Parkinson's in My Clinic: Cannabis.

Cannabis (in all the varied methods of delivery) continues to garner significant attention as a potential therapeutic intervention for neurodegenerative disorders, including Parkinson's disease (PD). The recent legalization of personal use of cannabis products in some parts of the world has increased this interest and with it, potential availability to many more people. However, such access has led to more questions than answers for both patients and health care professionals. These include what symptom(s) of PD will cannabis products treat; what dose; what type of cannabis product to use and what are the side effects?

Traditional knowledge of baniwa peppers

It examines the scientific and technological context that surrounds the production of the Pimenta Baniwa product and the protection of its originality, with the aim of discussing the issue of traditional knowledge that involves indigenous entrepreneurship in the Amazon. The focus of the study is the trajectory of the composition of the Pimenta Baniwa product type Jiquitaia and indigenous female protagonism. It establishes as a methodological element the metric studies of information, especially the bibliometric and patentometric field to measure the scientific and technological state of the topic, analyzing the mapping of scientific production on the topic using bibliometrics and technological indicators in patentometrics. The results demonstrate that there is a lot of scientific and technological material that contains pepper from the genus Capsicum ssp. as the main theme, however, when it comes to Baniwa Pepper, little is found within scientific research and regarding the technological domain, no type of protection directed to the product was found. It is concluded that the production of knowledge on the topic discussed is predominantly focused on the agrarian field, with an emphasis on expanding production and safeguarding pepper, with notable little production that addresses in depth the indigenous entrepreneurship of the Baniwa people.

Use of patent term extensions to restore regulatory time for medical devices in the United States

ABSTRACT Background Medical devices can seek patent term extensions (PTEs), which extend market exclusivity to compensate for delays related to clinical trials and regulatory review. Pharmaceutical companies commonly use PTEs, but their use by medical device companies has not been clear. Research Design and Methods We examined the use of PTEs by medical device companies between 1984 and 2024 using a database published in the Federal Register and a list published by the Patent and Trademark Office. Results Only 178 medical device submissions were linked to a PTE application. They were mostly concentrated in 116 product codes associated with 15 medical specialties; nearly half were associated with cardiovascular devices. Numbers increased significantly in the past decade. Successful applications restored 987 days on average. Conclusions The patent restoration opportunity appears underutilized. It is unclear whether some companies do not recognize the opportunity it promises, or whether it does not meet their needs. Different business features and marketing strategies in device versus pharmaceutical industries may decrease the usefulness of the PTE program for these types of medical products. However, the finding that a small subset of manufacturers operating in competitive markets adopted patent extension strategies more commonly suggests a significant competitive advantage when competition increases.

Impact of nano-silica on the mechanical properties of lightweight concrete

Abstract Recent research has shown that lightweight concrete (LWC) offers a series of advantages, leading to a noteworthy evolution in this field. Numerous high-performance features are offered by nanomaterials added to LWC. This study examines the impact of nano-silica (NS) at concentrations of 1 %, 3 %, 5 %, 10 %, 15 %, and 20 % on the properties of LWC both fresh and hardened. Slump tests were used to estimate the workability of all mixes. To assess for toughened qualities, tests for density, compressive strength, and microstructure were employed. In comparison to the reference mixture, the application of NS improved the microstructure and total compressive strength. The percentage of NS at 5 % with a 90-day increase the compressive strength by 77 %. The microstructure analyses demonstrate that the hydration process of the cement paste can be changed with the addition of nano-silica, and new types of hydration products have been observed in nano-modified cementitious matrix. The interface between the lightweight aggregates and the cement paste can be reinforced by nano-silica due to the new types of hydration products.

Empirical Analysis of Food Losses and Waste in Ukraine

Abstract At each stage of the food chain, the cost of food losses differs significantly. Also, they are significantly differentiated depending on the type of products and the region, which requires different approaches to solving this problem. The purpose of our research is to assess the degree of impact of food losses and waste at each of the stages of the food chain in their total volume for a specific type of product. The empirical research was conducted using primary sources and secondary data. Primary sources were used to calculate food losses and waste according to the FAO methodology. Secondary data were used for correlation and regression analysis. According to the results of the correlation and regression analysis, the assumption of relationship absence is not confirmed, all factors are significant. It was established that the greatest impact on the volume of food losses and waste per person occurs at the stages of production and consumption, except potatoes and vegetables – the greatest impact on the amount of food losses in these groups is caused by losses at the stage of delivery and sale, at the same time food losses at the stage of handling and storage have the least impact on the performance indicator – physical restriction of access to food. The results of this empirical study are a necessary condition for making appropriate management decisions regarding the implementation of measures to achieve SDG 2, 12 in Ukraine.

Assessing the nutrient content of plant-based milk alternative products available in the U.S.

Consumption of plant-based milk alternatives is increasing. Current dietary guidance primarily relies on dairy milk as a source of key nutrients of public health concern including calcium and vitamin D. To compare the nutritional content of plant-based milk alternatives between categories (e.g., soy, almond, and oat) and with dairy milk. This study presents an evaluation of the nutritional content of 219 plant-based milk alternatives from 21 brands available in the US marketplace using data from the University of Minnesota Nutrition Coordinating Center's (NCC) database. Nutrients of focus include those identified as nutrients of public health concern in the Dietary Guidelines for American's (DGA) or used by the United States Department of Agriculture (USDA) as criteria for determining whether a plant-based milk is a suitable substitute for dairy milk. Most data are presented as percent Daily Values (% DV). Nutrients and food components were compared using means, medians, interquartile ranges (IQR), and ranges. Statistical tests for significance were not used to evaluate between category differences because the plant-based milk alternatives included are a full census of the products from 21 brands available in the marketplace. Because data are a census, differences can be understood to be true differences. Fortified soy-based products most closely mimic the nutrient content of dairy milk. High variability was present in all the nutrients and food components. Plant-based milk alternatives were generally lower in protein and saturated fatty acids than dairy milk, with high variability in added sugars content. Approximately 70% were fortified with both calcium and vitamin D. These results indicate that most plant-based milk alternative products are not nutritionally equivalent to dairy milk, and there is high nutritional variability between and within product types. These findings highlight the importance of communicating the nutritional differences between plant-based milk alternatives and dairy milk to consumers.

Modeling of Determinants’ Influence on Consumer Behavior Towards Counterfeit Products in Indonesia and Malaysia

This study investigates customer behavior in the context of purchasing counterfeit products. Specifically, it seeks to assess consumer awareness regarding value consciousness, ethical considerations, and legal sensitivity, which are believed to impact their attitudes and behavior. The study was carried out in both Indonesia and Malaysia. This study uses Smart PLS as a quantitative method and includes a sample of 360 respondents from Indonesia (180) and Malaysia (180) who have bought different types of counterfeit products. This study provides evidence that there is no significant disparity in the consumption intentions of counterfeit products between Indonesians and Malaysians since both nations display a similar trend. The results from both countries are in agreement, indicating that value awareness has a favorable and substantial impact on attitudes, personal gratification has an unfavorable and significant effect on attitudes, ethical sensitivity has a favorable and substantial impact on attitudes, and legal sensitivity has a favorable and substantial effect on attitudes. The impact of attitudes on behavioral intentions is positive and essential, as are subjective norms, perceived behavioral control, and habits. Policymakers must acknowledge this conclusion, as business entities that become victims of counterfeit products will inevitably encounter significant challenges if this issue remains unattended. The issue of counterfeit goods in Indonesia and Malaysia has substantial financial implications for both the government and enterprises. Consequently, law enforcement agencies assume a crucial role in addressing this problem.

Tensor Golub–Kahan method based on Einstein product

The Singular Value Decomposition (SVD) of matrices is a widely used tool in scientific computing. In many applications of machine learning, data analysis, signal and image processing, the large datasets are structured into tensors, for which generalizations of SVD have already been introduced, for various types of tensor–tensor products. In this paper, we present innovative methods for approximating this generalization of SVD to tensors in the framework of the Einstein tensor product. These singular elements are called singular values and singular tensors respectively. The proposed method uses the tensor Lanczos bidiagonalization applied to the Einstein product. In most applications, as in the matrix case, the extremal singular values are of special interest. To enhance the approximation of the largest or the smallest singular triplets (singular values and left and right singular tensors), a restarted method based on Ritz augmentation is proposed. Numerical results are proposed to illustrate the effectiveness of the presented method. In addition, applications to video compression and facial recognition are presented.

Prolonged multi‐country outbreak of Listeria monocytogenes ST173 linked to consumption of fish products

Abstract Between 2012 and 2024, a prolonged outbreak of 73 cases of L. monocytogenes ST173 infections (‘My2’ ‐cluster) has been ongoing in Belgium (5), Czechia (1), Germany (39), Finland (2), Italy (1), the Netherlands (20), and the United Kingdom (UK) (5). Fourteen deaths have been recorded as associated with this outbreak. Males aged over 60 years represent the most affected population group. Most patients with available information from case interviews report consuming various fish products before illness. Among 73 cases, an ongoing ‘My2’ sub‐cluster 1 was identified with 38 cases reported in six EU countries and the UK. The ‘My2’ sub‐cluster 1 includes 83 non‐human isolates, of which 48 are food isolates and six are environmental isolates with traceability data corresponding to 37 fish products (different typologies) and 12 fish manufacturers (located in six EU countries and one third country). The epidemiological and traceability information did not allow identification of a single common point or food business operator in the traceability of all products. Five countries reported the implementation of control measures. The whole genome analysis (WGS) analysis, the tracing evidence, and the detection in fish products between 2017 and 2024 suggest that the strain has been geographically spread in Europe for several years, most likely originated from a past single source high up in the production chain, and has been established in different fish processing plants. Overall, the evidence supports the hypothesis of fish products as the vehicle of infections. Given the detection of the outbreak strain in multiple types of fish products and its wide circulation in the EU/EEA fish production chain, new cases are likely to be reported. Corrective measures should be implemented in the plants where the contamination is detected, and further investigations should be carried out to identify the point of entry and prevent possible re‐contamination.
