Abstract
This article describes a study that has been made on the automation of deburring in a foundry. Circular castings weighing up to 20kg are deburred before delivery in order to make them fit into machining cells. The maximum production rate of the cylindrical castings on the foundry line is one casting every ten seconds. However, the castings are produced in small batches, typically ranging from 100 to 1,000. After casting and integrated sand blasting and cooling chambers, the castings are transferred further on a conveyor belt. Deburring is today done manually by lifting and pressing against different grinding and deburring machines. Bins and forklifts are used in transport and storage of castings, from production line to deburring and shipment.

Abstract
Purpose
The purpose of this paper is to design an integrated localization system for mobile robots in underground environments for exploring and rescuing tasks after incidents and detection of hazard gas in tunnels before ingress.
Design/methodology/approach
An integrated localization system mainly based on a strap‐down inertial measurement unit and a digital compass is designed for exploring and rescuing task in coal mines and tunnels. After a system model was founded, a filtering algorithm combining a wavelet‐based pre‐filter with unscented Kalman filters was developed for reckoning tracks of robots and localizing it.
Findings
Based on this research, an integrated localization system for robots in underground environments can be developed to explore some regions and rescue people. Although errors of localization exist, performance of the integrated system should be improved if some sensors and landmarks or maps of tunnels are introduced.
Originality/value
What is proposed in this paper is an integrated localization system used in underground environments. In this research, property of environments has been taken into account as an important disturbance when filtering thresholds were set.

Abstract
Promoting mental health and meeting the needs of the large numbers of the general public with problems of anxiety and depression is a big challenge. Particular difficulties are the low capacity of the therapy services and the reluctance of the general public to seek help. The aim of this study was to compare the attendance, effectiveness and characteristics of participants self‐referring to six different psycho‐educational workshops, each using non‐diagnostic titles: self‐confidence; stress; sleep; relationships; happiness; and anger. The series of day‐long workshops ran for one year and were offered to members of the general public in south east London. Over a quarter had not previously sought help from their GP. The take‐up rates for the self‐confidence, sleep and anger workshops were highest and one month after attending these workshops, participants reported significantly lower depression and distress. It was concluded that a self‐referral route to some day‐long workshops can attract quite large numbers of the general public and provide access to effective psychological treatment. These workshops can be used as an effective way of promoting mental health and improving the provision of evidence‐based mental health treatment in the community, possibly within the Improving Access to Psychological Treatments (IAPT) programme in the UK.

Reviews the benefits and potential application of tactile sensors for use with robots.
Abstract
Purpose
Reviews the benefits and potential application of tactile sensors for use with robots.
Design/methodology/approach
Includes the most recent advances in both the design/manufacturing of various tactile sensors and their applications in different industries. Although these types of sensors have been adopted in a considerable number of areas, the applications such as, medical, agricultural/livestock and food, grippers/manipulators design, prosthetic, and environmental studies have gained more popularity and are presented in this paper.
Findings
Robots can perform very useful and repetitive tasks in controlled environments. However, when the robots are required to handle the unstructured and changing environments, there is a need for more elaborate means to improve their performance. In this scenario, tactile sensors can play a major role. In the unstructured environments, the robots must be able to grasp objects (or tissues, in the case of medical robots) and move objects from one location to another.
Originality/value
In this work, the emphasis was on the most interesting and fast developing areas of the tactile sensors applications, including, medical, agriculture and food, grippers and manipulators design, prosthetic, and environmental studies.

Abstract
This paper highlights the social context of common mental disorders in primary care and the paucity of evidence relating to effective social interventions. It introduces the ABC‐E Model of Emotion, which combines social interventions with psychological therapy, and discusses how the implementation of the new role of graduate primary care mental health worker (GPCMHW) provides an opportunity for holistic practice in helping individuals experiencing mild to moderate mental health difficulties in primary care. It provides a case example of the implementation of the ABC‐E model and makes recommendations for further research including the evaluation of the model and GPCMHW training programmes.

Abstract
Examines over the period from 1975 to 2000 the attitudes of Finnish consumers toward the products and associated marketing practices of Japan in comparison to those the United States. Concludes that, although there are significant differences between the attitudes of consumers toward the products and practices of the Japan and the U.S., the ratings of Japan and the U.S. typically improved over the period in distinctive ways. Raises some strategic implications for Japanese and U.S. firms who market their products in the European Union.

Abstract
Purpose
This paper aims to improve the understanding of student readiness for universal design for learning (UDL), thereby reducing a barrier to its adoption by management faculty. It explores how students’ personality (conscientiousness and openness to experience) affects their readiness to embrace UDL and investigate how that relationship is mediated by self-directed learning (SDL).
Design/methodology/approach
Analysis uses survey data from students in management courses. From these data are created multi-item constructs and control variables. A mediated regression model that uses bootstrapping to estimate parameters and standard errors generates the results.
Findings
The findings were that SDL is strongly related to student readiness for UDL and that SDL fully mediates the relationship between conscientiousness and UDL. Openness to experience, however, directly relates to UDL without any mediation.
Research limitations/implications
This research applies only to one institution and two management courses. The methodology used in this study is limited to one part of the UDL model, which is a measure of student readiness to engage in choice. Future research can extend this model to other courses and institutions and other parts of the UDL model.
Practical implications
These findings provide insight into the student characteristics that enable them to gain empowerment and motivation from the UDL approach. Implementation of UDL in management education may require learning management strategies that accommodate student readiness for UDL. This study makes progress in identifying student characteristics that explain this readiness.
Social implications
UDL can improve management education by making it more accessible to students with different personalities and learning styles.
Originality/value
This study developed a method for analyzing the applicability of UDL in management education. It also devised and implemented a new survey measure for student readiness for UDL.

Abstract
Purpose
The purpose of this paper is to compare the construction of health knowledge in the Finnish national curriculum and recent Finnish health education textbooks, at primary and secondary levels of education. The authors examine the visual and textual content of the textbooks in an attempt to identify their pedagogical style and approach to health education.
Design/methodology/approach
The study is part of an international, European Union funded, FP6 STREP Project, Biohead‐Citizen. Conceptual health knowledge construction is analysed evaluating the emphasis placed on a biomedical model or on a health promotion ( HP) approach. Pedagogical style of the text and illustration is classified as either neutral, persuasive, participative or injunctive, out of which especially persuasive and participative reflect the constructionist approach.
Findings
The textbooks cover a wide range of health topics and meet the core contents of the national curriculum. The approach used was primarily that of HP and used a persuasive and participative approach. The pedagogical style of text, tasks and illustrations reflected current pedagogical thinking.
Research limitations/implications
The study encourages future research to explore the effects of pedagogical construction on materials and learning in health education.
Originality/value
The paper usefully analyzes the pedagogical properties of recent Finnish health knowledge textbooks.

Abstract
Purpose
The purpose of this paper is to develop an effective approach to decide design details using benchmarking to capture the existing practice in sustainable design.
Design/methodology/approach
This paper reports a systematic method for sustainable product design. The method uses benchmarks as references searching for design details to achieve sustainable solutions. Quality function deployment is used to guide the search process for competitive products using benchmarking to meet quantitative targets of product and to increase knowledge for sustainable design.
Findings
The proposed method can meet both functional and sustainable requirements of product design. 18.55 percent reduction in carbon equivalent emissions is achieved compared to benchmarks in wheelchair design. The research reveals that when weight, material and number of components used in product decrease, environmental footprints and cost of the product improve.
Originality/value
The research improves the existing method of sustainable product design. Both sustainable requirements and functional demands of product are identified from qualitative criteria to quantitative metrics using benchmarking and the life cycle assessment.
