Sensory investigations of the functional textiles could be an alternative for the quality inspection and control of the products. The purpose of this research is to use subjective evaluation technique for assessing the tactile comfort of some functional textile fabrics based on AATCC Evaluation procedure 5-2011. Blind subjective evaluations and visual subjective evaluations were performed for sensory investigation. Ten fabric-skin-contact and comfort-related sensory properties were used to evaluate the handle of the functional textile fabrics. The reliability of the sensorial data obtained by subjective tests was evaluated using statistical data analysis techniques. A minimum and maximum consensus distances recorded were 0.58 and 1.61, respectively, using a descriptive sensory panel analysis and proves the consistency and similar sensorial perception between panelists. The Pearson correlation coefficient between panelists was up to 96% and hence a strong agreement between the panelist’s judgment. The results allowed to consider the subjective evaluation using a panel of experts could be validated in the case of functional fabrics. For functional textiles, additional visual subjective evaluation should be considered to have a similar human perception in addition to blind subjective evaluation.

Abstract DECAFF is a method for design and control of haptic interfaces that utilizes a DE-Coupled Actuator and Feed-Forward control. In this paper results of an experimental investigation are presented that quantify improved human haptic perception while using the DECAFF system, compared to the traditional haptic interface design and control systems. Perception improvements include the increased stability for rigid surfaces and increased ability of subjects to accurately identify initial contact with virtual surface boundaries. Traditional haptic interfaces employ an actuator directly coupled to the human operator that provides a force proportional to wall penetration distance and velocity. The DECAFF paradigm for design and control of haptic displays utilizes a de-coupled actuator and pre-contact distance sensing as a feed forward control term to improve stability and response performance. A human perception experiment has been performed that compares the touch sensation of the subjects for both the DECAFF system and traditional approaches to haptic display. In the human factors study the quality of rigid body display is evaluated in addition to the sensitivity of touch experienced by the subjects while making initial contact with virtual surfaces.

The present study investigated the effect of using scrambled cloze procedure on reading and writing among intermediate EFL learners. To fulfill the purpose of the study, 60 participants were tested on a PET test, from whom 48 homogeneous participants were selected and assigned randomly to two groups of 25 and 23, as experimental and control group. Then, both groups were given a pre-test of writing and reading comprehension. During 14 sessions, the experimental group were provided with scrambled cloze samples and tasks while practicing paragraph writing and reading, whereas the control group did not, while they were practicing paragraph writing and reading. At the end, the two groups were tested in reading comprehension and writing, based on a posttest. Two raters scored the writing samples collected from two groups in the pre and posttest. Pearson correlation was used to compute the inter-rater reliability. The results showed the experimental group outperformed the control group in paragraph writing and reading comprehension. However, it was found that gender did not make a significant difference in reading comprehension and writing performance.

The topic of metamemory had attracted the attention of many researchers and scholars in the field of educational and cognitive psychology, especially how individuals become aware of and control their memory functions. Therefore, the aim of the present study was to build a psychometric scale/questionnaire for measuring metamemory. The study was conducted among a sample of 200 students joining Sharia/Islamic Law, Arabic Language, Education, English Language, Science, Economics and Management at Al Qassim University. For the purpose of the content validity of the scale, it was verified by the raters’ agreement and the internal consistency of the items of the scale. Pearson correlation coefficient was also used to calculate correlation coefficients between the scores of each item and its dimension to ensure consistency and homogeneity of the items and dimensions of the scale. The correlation coefficients of the items of the scale and the total score of the dimension to which the items belong were all positive correlation coefficients and statistically significant at the level of 0.01, which confirms the consistency and homogeneity of the items of each dimension. The homogeneity of the dimensions of the scale was also verified by calculating Pearson correlation coefficients between the score of each dimension and the overall score of the scale. The reliability of the scale and its sub- dimensions was verified using the α- Cronbach Alpha coefficient. The results showed that the scale and its sub- dimensions had high and statistically acceptable validity and reliability coefficients. Such result indicates that the scale is statistically valid and reliable.

Anaphylaxis is the most common allergic reaction triggered by allergens such as insect poisons, food, and drugs through skin contact, injection, or inhalation. In vitro previous research showed that strawberries fruit have activity as antioxidant, anticancer, anti-inflammation, and anti-allergic. The research aimed to determine the antianaphylaxis strawberry fruit extract in mice (Balb/C strain) with ovalbumin-induced.  Twenty-four Balb/C strain mice were divided into six groups (n=4). Group I and II as a normal and control group. Group III till VI as a treatment group was given cetirizine dose 0.042 mg/20 g BW and strawberry extract doses 0,68; 1,36; and 2,72 mg/20 g BW, respectively. This research showed that 70 % of ethanol extract of strawberries fruit have antiallergic activity in response to active cutaneous anaphylaxis. 70% ethanol extract of strawberries doses 2.72 mg/20 g BW had similar antiallergic activity compare with cetirizine. The conclusion of this study showed that strawberries fruit extract could be developed as an alternative medicine to anti-anaphylaxis or anti-allergic.

While the psychophysics of weight perception may help assess the effort needed in manual material handling tasks, the perception of weight is subjective and not necessarily accurate. The purpose of this study was to examine weight perception during standing and walking. Participants (n=10) performed a series of weight comparison trials against a reference load while holding loads (standing) or carrying loads (walking). Polynomial logistic regression models were built to examine the effects of walking, box weight ratio, and reference weight level on the probability of detecting a weight difference. The results showed that weight ratio and reference weight level had statistically significant effects on the detection probability while walking did not have a significant effect. Findings from this study can help inform the design of subjective evaluation of job demands involving motion, and it can be further extended to the gradual increase in load of strengthening tasks in therapeutic exercises.

The outbreak of COVID-19 pandemic has generated unprecedented information on preventive strategies aimed at containment and control of the disease. This study examined the relationship between perceived credibility of information sources and adoption of COVID-19 preventive strategies among residents in South West Nigeria. The study adopted Elaboration Likelihood Model (ELM), while online survey and in-depth interview (IDI) were employed as the research designs. Convenience and purposive sampling procedures were used in the selection of 259 respondents and ten participants who were 18 years and above. Data were generated using questionnaire and interview guide. Descriptive statistics, Pearson correlation and multiple bootstrapping comparison test were used to analyse quantitative data, while qualitative data were transcribed and direct quotations that represented the participants’ opinions were used for the analysis. Key findings showed that expertise and trustworthiness determined the credibility of information sources while television was perceived as the most credible source of information. A significant relationship exists between perceived credibility of information sources and adoption of preventive measures. These findings highlight the need for preventive strategies to be disseminated through credible information sources.

The Relationship

The human–environment relationship is bidirectional, meaning that human attitudes and behavior to nature are at the root of environmental change, while changes in the environment affect human attitudes and behavior. It is necessary to analyze the human–environment relationship from two aspects: (a) Whether there is a good objective basis for maintaining an environment, and (b) whether people report that they are satisfied with that environment. This study attempted to construct a framework to evaluate the human–environment relationship considering these two aspects. The framework consists of three parts: Traditional evaluation, indicator construction, and evaluation considering the relationship between subjective and objective assessment. Traditional evaluations consist of subjective evaluations and objective assessments. Indicator construction focuses on putting forward indicators that quantitively evaluate the human–environment relationship, considering the results of objective assessments and subjective evaluations. The indicators introduced in this study include MD (match degree) and OSC (objective assessment and subjective evaluation comparison) to explain the difference and the relationship between objective assessments and subjective evaluations of the environment. Then, based on the indicator value, a matrix containing four situations (Match-H, Match-L, H-L, and L-H) was constructed to explore why a human–environment relationship may not be harmonious. Since the upper Minjiang River basin is a typical area, because of its intensive human activity, as well as its fragile ecological environment, this study chose it as a case study and used it to verify the framework. Through the framework construction and application, this study found that: (1) The framework of this study provided a more comprehensive method to evaluate the human–environment relationship; (2) as the subjective evaluation was based on individual comprehensive tradeoffs, the evaluation combining the subjective and objective assessment was more accurate; (3) environmental conditions were the basis, and human activities were the key factors, for the coordination of human–environment relationships; so the matrix put forward in this study was necessary for finding the cause of human–environment incongruity.

Abstract Background In recent years, the role of neuroinflammation and oxidative stress in migraine pathogenesis has achieved considerable interest; however, to date findings are equivocal. Thus, the objective of this study was to investigate biomarkers of oxidative stress in episodic and chronic migraineurs (EM and CM patients) and controls. Methods Forty-four patients with EM, 27 individuals with CM and 19 age-sex-matched controls were enrolled. After collecting data on demographic and headache characteristics, blood samples were collected and analyzed to detect serum levels of oxidative stress biomarkers (malondialdehyde (MDA) and nitric oxide (NO)); total antioxidant capacity using Trolox equivalent antioxidant capacity (TEAC) assay; and antioxidant enzymes (catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase-1 (GPx-1)). Results Serum levels of CAT and SOD were significantly lower in the CM group than the EM group and controls. However, serum GPx-1 levels of the CM patients were slightly higher than the EM patients and controls (P-value≤0.001). CM patients had lower mean TEAC values than EM patients and controls. In addition, serum levels of NO and MDA were significantly elevated among subjects with CM compared to EM and control individuals (P-value≤0.001). Pearson correlation analysis revealed negative correlations between the number of days of having headaches per month and serum concentrations of the two antioxidant enzymes CAT (r = − 0.60, P-value< 0.001) and SOD (r = − 0.50, P-value< 0.001) as well as TEAC values (r = − 0.61, P-value< 0.001); however, there were positive correlations between headache days and serum GPx-1 levels (r = 0.46, P-value< 0.001), NO (r = 0.62, P-value< 0.001), and MDA (r = 0.64, P-value< 0.001). Conclusion Present findings highlighted that chronic migraineurs had lower total non-enzymatic antioxidant capacity and higher oxidative stress than episodic migraineurs and control individuals. Although more studies are needed to confirm these data, applying novel prophylactic medications or dietary supplements with antioxidant properties could be promising in migraine therapy.

Summary Metabolic changes resulting from obesity, insulin insensitivity, and imbalances in hormones such as adiponectin, leptin, resistin, apelin and visfatin, which are derived from white adipose tissue-derived hormone, are directly linked to both colon cancer (CC) and inflammatory bowel diseases increasing tissue-derived risk. We conducted this study to evaluate the relationship between the circulating concentrations of adiponectin, leptin, resistin, apelin and visfatin and colon adenoma and CC. Our study included 90 participants aged >18 years who were divided into three groups: colon cancer, adenoma and control. The serum concentrations of the investigated adipohormones were measured with ELISA in 30 patients with colon adenoma, 30 with CC and 30 controls with no colon pathology. Demographic, anthropometric, metabolic and hormonal parameters were also recorded. The group means were compared by using one-way analysis of variance (ANOVA). Dual comparisons between groups were analyzed with the Tukey test. Pearson correlation coefficient was used to determine the relation between continuous variables. Adiponectin and leptin levels in patients with adenomas (p<0.000; p<0.000, respectively) and CC (p<0.000; p<0.000, respectively) were lower than in controls. Apelin level in patients with CC (p<0.000; p<0.000, respectively) was lower than in patients with adenomas and in controls. Resistin and visfatin levels in patients with CC (p<0.000; p<0.000, respectively) were higher than in patients with adenomas and in controls.
