Abstract

Purpose

The purpose of this paper is to propose a whole set of methods for underwater target detection, because most underwater objects have small samples, low quality underwater images problems such as detail loss, low contrast and color distortion, and verify the feasibility of the proposed methods through experiments.

Design/methodology/approach

The improved RGHS algorithm to enhance the original underwater target image is proposed, and then the YOLOv4 deep learning network for underwater small sample targets detection is improved based on the combination of traditional data expansion method and Mosaic algorithm, expanding the feature extraction capability with SPP (Spatial Pyramid Pooling) module after each feature extraction layer to extract richer feature information.

Findings

The experimental results, using the official dataset, reveal a 3.5% increase in average detection accuracy for three types of underwater biological targets compared to the traditional YOLOv4 algorithm. In underwater robot application testing, the proposed method achieves an impressive 94.73% average detection accuracy for the three types of underwater biological targets.

Originality/value

Underwater target detection is an important task for underwater robot application. However, most underwater targets have the characteristics of small samples, and the detection of small sample targets is a comprehensive problem because it is affected by the quality of underwater images. This paper provides a whole set of methods to solve the problems, which is of great significance to the application of underwater robot.

Abstract

Purpose

Many students are found facing difficulties in learning English due to plenty of reasons: known and unknown ones. In order to overcome such an issue, the instructors have to explore for effective techniques of teaching English to motivate learners by any means. Technology in general and informatics in particular can be thought of as innovative tool of pedagogy in the current teaching-learning environment. The present proposal of research aims at creating innovative approaches, which attract learners' interest and catch their attention for better outputs.

Design/methodology/approach

Following subsections have been discussed keeping the significance in view. Setting of the study: The present study was conducted at King Abdulaziz University, Jeddah-Saudi Arabia, which is one of the Saudi Arabian universities; however, it has opened up new avenues for the pedagogues, teachers of English and researchers to conduct studies in various allied fields. In order to have a representative sample of students' population, the participants were chosen from the “preparatory year”. Material and tools: This study used a questionnaire (Appendix) and a test to evaluate performances of the two groups: controlled and experimental. In order to further strengthen the findings, semi structured interview was conducted for a few select students from the student-sample. Since the questionnaire was adapted, the statistical validity and reliability was not considered to be essential; however, content/face validity was ensured by consulting 10 experts in the field of education/methods of teaching.

Findings

Based on the analysis of data gathered from the test performances of the two groups of students, it was found that there existed a significant difference in the test scores. The questionnaire responses also proved that infographics can be proved to be an interesting tool of education in general and English language teaching in particular. However, it has been noticed from the gathered data that not many teachers are comfortable using multimedia or infographics for different reasons. The results of the present study are in line with the study by Rezaei and Sayadian (2015) that support the idea of infographics that would help English teachers to develop understanding and insights to design among the learners. They further contend that the infographic instruction offers choices for the utilization of collaborative activities. In addition, the infographics enhance students' performance as a whole as also supported by Alrwele (2017).

Research limitations/implications

The study was conducted on a small sample which might affect the generalization of the outcomes. It was carried out with special reference to teaching of vocabulary and reading.

Practical implications

There can be many recommendations for different stakeholders. For teachers, it is recommended that they should know about the significance of infographs for catching the attention of students. They should know how to design interesting and colorful infographs. The administration/management should facilitate the teachers with the required software or platform to create infographics and integrate in an English language class. In addition, teachers should attend workshops and training courses organized for topics related to the infographs.

Originality/value

The author checked the study for plagiarism (excluding references) and found it to be 93% plagiarism free.

Abstract

Purpose

Spatial olfactory design in the library appears to be a practical approach to enhance the coordination between architectural spaces and user behaviors, shape immersive activity experiences and shape immersive activity experiences. Therefore, this study aims to explore the association between the olfactory elements of library space and users’ olfactory perception, providing a foundation for the practical design of olfactory space in libraries.

Design/methodology/approach

Using the olfactory perception semantic differential experiment method, this study collected feedback on the emotional experience of olfactory stimuli from 56 participants in an academic library. From the perspective of environmental psychology, the dimensions of pleasure, control and arousal of users’ olfactory perception in the academic library environment were semantically and emotionally described. In addition, the impact of fatigue state on users’ olfactory perception was analyzed through statistical methods to explore the impact path of individual physical differences on olfactory perception.

Findings

It was found that users’ olfactory perception in the academic library environment is likely semantically described from the dimensions of pleasure, arousal and control. These dimensions mutually influence users’ satisfaction with olfactory elements. Moreover, there is a close correlation between pleasure and satisfaction. In addition, fatigue states may impact users’ olfactory perception. Furthermore, users in a high-fatigue state may be more sensitive to the arousal of olfactory perception.

Originality/value

This article is an empirical exploration of users’ perception of the environmental odors in libraries. The experimental results of this paper may have practical implications for the construction of olfactory space in academic libraries.

Abstract

Purpose

In this paper, the brain potential changes caused by touching fabrics for handle evaluation were recorded by event related potential (ERP) method, compared with subjective evaluation scores and physical index of KES, explore the cognitive mechanism of the transformation of tactile sensation into neural impulses triggered by subtle mechanical stimuli such as material, texture, density and morphology in fabrics. By combining subjective evaluation of fabric tactile sensation, objective physical properties of fabrics and objective neurobiological signals, explore the neurophysiological mechanism of tactile cognition and the signal characteristics and time process of tactile information processing.

Design/methodology/approach

The ERP technology was first proposed by a British psychologist named Grey Walter. It is an imaging technique of noninvasive brain cognition, whose potential changes are related to the human physical and mental activities. ERP is different from electroencephalography (EEG) and evoked potentials (EP) on the fact that it cannot only record stimulated physical information which is transmitted to brain, but also response to the psychological activities which related to attention, identification, comparison, memory, judgment and cognition as well as to human’s neural physiological changes which are caused by cognitive process of the feeling by stimulation.

Findings

According to potential changes in the cerebral cortex evoked by touching four types of silk fabrics, human brain received the physical stimulation in the early stage (50 ms) of fabrics handle evaluation, and the P50 component amplitude showed negative correlation with fabric smoothness sensations. Around 200 ms after tactile stimulus onset, the amplitude of P200 component show positive correlation with the softness sensation of silk fabrics. The relationship between the amplitude of P300 and the sense of smoothness and softness need further evidence to proof.

Originality/value

In this paper, the brain potential changes caused by touching fabrics for handle evaluation were recorded by event related potential (ERP) method, compared with subjective evaluation scores and physical index of KES, the results shown that the maximum amplitude of P50 component evoked by fabric touching is related to the fabrics’ smoothness and roughness emotion, which means in the early stage processing of tactile sensation, the rougher fabrics could arouse more attention. In addition, the amplitude of P200 component shows positive correlation with the softness sensation of silk fabrics.

Abstract

Purpose

The paper aims to discuss error detection and correction in Kashmiri carpet weaving (KCW), mediated by cryptographic code, Talim which is held to guarantee accurate information transference from designing to weaving, even after hundred years. Yet, carpets often show errors on completion.

Design/methodology/approach

Human factors analysis revealed error emergence, detection and correction in this practice whose task domains are distributed over large geographies (from in-premises to several kilometers) and timescales (from days to decades). Using prospective observation method, production process of two research carpets from their design, coding and weaving was observed while noting the errors made, identified and corrected by actors in each phase.

Findings

The errors were found to emerge, identified and corrected during different phases of designing, coding and weaving while giving rise to fresh errors in each phase, due to actors’ normal work routines.

Originality/value

In view of this, usual branding of “weaver-error” behind flawed carpet turns out to be misplaced value judgment passed in hindsight.

Abstract

Purpose

An increasing number of images are generated daily, and images are gradually becoming a search target. Content-based image retrieval (CBIR) is helpful for users to express their requirements using an image query. Nevertheless, determining whether the retrieval system can provide convenient operation and relevant retrieval results is challenging. A CBIR system based on deep learning features was proposed in this study to effectively search and navigate images in digital articles.

Design/methodology/approach

Convolutional neural networks (CNNs) were used as the feature extractors in the author's experiments. Using pretrained parameters, the training time and retrieval time were reduced. Different CNN features were extracted from the constructed image databases consisting of images taken from the National Palace Museum Journals Archive and were compared in the CBIR system.

Findings

DenseNet201 achieved the best performance, with a top-10 mAP of 89% and a query time of 0.14 s.

Practical implications

The CBIR homepage displayed image categories showing the content of the database and provided the default query images. After retrieval, the result showed the metadata of the retrieved images and links back to the original pages.

Originality/value

With the interface and retrieval demonstration, a novel image-based reading mode can be established via the CBIR and links to the original images and contextual descriptions.

Abstract

Purpose

This research aims to examine the relationship between the physical environment and neuropsychological perception in children with Asperger’s disorder.

Design/methodology/approach

This study through mixed qualitative–quantitative approaches conducted strategies including a survey and case study. Accordingly, multiple methods were applied to collect data including semi-structured expert interviews (20 persons) and questionnaires (N = 400). The sampling strategy of questionnaire participants was random clustering and the target population was children with Asperger from Iran Asperger Support Associations. Besides, the sampling strategy for the participants of semi-structured expert interviews was non-random and purposeful. The collected data from the participant’s questionnaires and interviews were analyzed by Porsline and Excel software and content analysis, respectively.

Findings

Based on the relationship between the physical environment and neuropsychological perception, the results of the research indicate that despite all existing differences between the two spectra of hyper-sensitive and hypo-sensitive behaviors, it is possible to design architectural spaces responding to their common needs and satisfy both spectra.

Originality/value

This research on to healing aspect is quite new and contributes significant information about health issues in building design. This study tries to derive and examine the supportive characteristics of architectural spaces that integrate special physical and effective designs to improve the healing process of children with Asperger’s disorder.

Abstract

Purpose

Despite significant advances in previous work, there are still gaps in the research on customers' acceptance of virtual fitting rooms (VFRs). This research aims to highlight the effects of the characteristics of VFRs on the intention to use.

Design/methodology/approach

Fashionable clothing shoppers in Harmony Shopping Plaza and Ginza Shopping Plaza in Jinan, China, were chosen as the main sample. A total of 304 valid questionnaires were collected using a questionnaire QR code, which was scanned to access the questionnaire. Structural equation modeling was used to test the relevant hypotheses.

Findings

The results showed that customers' usage intention (UI) was positively associated with perceived efficiency, design and perceived security. Furthermore, the mediating effects of perceived ease of use and perceived usefulness were significant between design, vividness and UI.

Originality/value

In contrast to existing research, which focuses primarily on the posterior effects of psychological perception and behavior, this paper focuses on the antecedents of customer psychological perceptions. This study also examines the moderating effect of fashion consciousness, which also provides reference value for future research. The findings of this paper provide practical guidance for the promotion of VFRs.

Abstract

Purpose

This study sought to understand which food allergen labeling systems (non-directive, semi-directive, and directive) were attended to and preferred by 34 participants with food hypersensitivity and their perceived corporate social responsibility (CSR) and behavioral intention towards a restaurant that identifies food allergens on menus.

Design/methodology/approach

This study used an online survey with open-ended and ranking questions, combined with eye-tracking technology, to explore participants' visual attention and design preferences regarding four menus. This study utilized one-way repeated measures analysis of variance (RM-ANOVA) and heat maps to analyze participants' menu-reading behaviors. A content analysis of survey responses and a ranking analysis of menus were conducted to understand the reasons behind consumers' preferred menu designs.

Findings

The advisory statement was not much attended to. Participants identified food allergen information significantly quicker with the directive labeling system (icons) than the other two systems, implying they were eye-catching. Semi-directive labeling system (red text) has lower visit count and was more preferred than two other systems; each labeling system has its strengths and limitations. Participants viewed restaurants that disclosed food allergen information on menus as socially responsible, and they would revisit those restaurants in the future.

Originality/value

This study was one of the first to explore, through use of eye-tracking technology, which food allergen labeling systems were attended to by consumers with food hypersensitivity. The use of triangulation methods strengthened the credibility of the results. The study provided empirical data to restauranteurs in the US on the values of food allergen identification on restaurant menus, although it is voluntary.

Abstract

Purpose

This study aims to consider the role of emotions, especially those related to empathy, in promoting a more humane education that enables students to reach out across kinship chasms to promote the development of communities predicated on a shared value on mutual respect. This attention to empathy includes a review of the rational basis for much schooling, introduces skepticism about the façade of rational thinking, reviews the emotionally flat character of classrooms, attends to the emotional dimensions of literacy education, argues on behalf of taking emotions into account in developmental theories and links empathic connections with social justice efforts. The study’s main thrust is that empathy is a key emotional quality that does not come naturally or easily to many, yet is important to cultivate if social justice is a goal of education.
