Abstract
Purpose
Product configuration is considered as one of the most successful applications of knowledge‐based approaches in the past decade. Knowledge‐based configurations can be classified into three different approaches, namely, rule‐based, model‐based and case‐based approaches. Past research has mainly focused on the development of reasoning techniques for mapping requirements to configurations. Despite the success of certain conventional approaches, the acquisition of configuration knowledge is usually done manually. This paper aims to explore fundamental issues in product configuration system, and propose a novel approach based on data mining techniques to automatically discover configuration knowledge in constraint‐based configurations.
Design/methodology/approach
Given a set of product data comprising product requirements specification and configuration information, the paper adopted an association rule mining algorithm to discover useful patterns between requirement specification and product components, as well as the correlation among product components. A configuration was developed which takes XML‐based requirement specification as input and bases on a constraint knowledge base to produce product configuration as output consisting of a list of selected components and the structure and topology of the product. Three modules are developed, namely product data modelling, configuration knowledge generation and product configuration generation module. The proposed approach is implemented in the configuration knowledge generation module. The configuration generation module realizes a resolution of constraint satisfaction problem to generate the output configuration.
Findings
The significance and effectiveness of the proposed approach is demonstrated by its incorporation in our configuration system prototype. A case study was conducted and experimental results show that the approach is promising in finding constraints with given sufficient data.
Originality/value
Novel knowledge generation approach is proposed to assist constraint generation for Constraint‐based product configuration system.

Abstract
Purpose
The research reported in this ongoing study aims to investigate the notion of knowledge assets developed within digital communities in the course of their economic or leisure activities. Ideally, the resulting knowledge is universal, affordable and relevant; this inclusiveness is a hallmark of any information or knowledge society.
Design/methodology/approach
The authors first synthesize the related research literature covering the areas of knowledge‐based economies, knowledge societies and knowledge policies. A model using 13 dimensions is then developed, which the authors claim is critical for creating a knowledge community in the digital economy. The model is validated against critique from a Delphi panel of researchers in the area.
Findings
While creating a knowledge society encompasses dimensions pertaining to infrastructure, governance, talent and culture, intangible assets are key to sustaining such societies. Governance and culture are instances of such intangibles. Talent may seem to be tangible but the human capacity for learning and development, which leads to an innovative culture, is less so. In any case, time is the essential ingredient for a knowledge culture to come about.
Research limitations/implications
Knowledge societies are not measurable constructs that can be described quantitatively and benchmarked with weighted summations of scores along prescribed dimensions. It would be a fallacy to treat the notion of a knowledge index as a socio‐economic measure of success.
Practical implications
. conclude with a practical view of how the dimensions may be best exploited in the course of a policy discussion on sustainable knowledge societies.
Originality/value
It is hoped that the research will provide a framework for policy makers and analysts to conduct qualitative discussions on creating and sustaining knowledge societies.

Abstract
Purpose
The purpose of this paper is to investigate the role of the National Library of Singapore in the life of Singaporeans.
Design/methodology/approach
The paper uses historical research. McMillan and Chavis’ theory of sense of community is adopted as the analytical framework to delineate the role of the National Library of Singapore.
Findings
The paper finds that the National Library of Singapore plays an important role in fostering a sense of community among Singaporeans. The transformation of the library to a truly public institution in 1950s effectively enlarged its boundaries. Upon joining the community of the library, local Singaporeans underwent a bidirectional process of influencing and being influenced. The library made strenuous efforts to meet the needs of Singaporeans in myriad ways, resulting in reinforcement of the sense of community among Singaporeans. A shared emotional connection in the community was engendered as a result of the frequent contact and high-quality interaction.
Originality/value
While being influenced by various social and cultural frameworks under which it operates, the library actively takes part in and influences the society. The study of the library in the life of the users via the lens of sense of community provides a perspective to further understand the potential and power of libraries and how libraries can positively contribute to the society at large.

Abstract
However, after Singapore's independence and separation from Malaysia on 9 August 1965, the PAP leaders were forced to change their vision of Singapore as part of Malaysia to Singapore as an independent nation, which they had earlier rejected. In other words, the PAP leaders had to “reinvent” Singapore to ensure its survival.

Abstract
Purpose
Soft robotics is currently a rapidly growing new field of robotics whereby the robots are fundamentally soft and elastically deformable. Fabrication of soft robots is currently challenging and highly time- and labor-intensive. Recent advancements in three-dimensional (3D) printing of soft materials and multi-materials have become the key to enable direct manufacturing of soft robots with sophisticated designs and functions. Hence, this paper aims to review the current 3D printing processes and materials for soft robotics applications, as well as the potentials of 3D printing technologies on 3D printed soft robotics.
Design/methodology/approach
The paper reviews the polymer 3D printing techniques and materials that have been used for the development of soft robotics. Current challenges to adopting 3D printing for soft robotics are also discussed. Next, the potentials of 3D printing technologies and the future outlooks of 3D printed soft robotics are presented.
Findings
This paper reviews five different 3D printing techniques and commonly used materials. The advantages and disadvantages of each technique for the soft robotic application are evaluated. The typical designs and geometries used by each technique are also summarized. There is an increasing trend of printing shape memory polymers, as well as multiple materials simultaneously using direct ink writing and material jetting techniques to produce robotics with varying stiffness values that range from intrinsically soft and highly compliant to rigid polymers. Although the recent work is done is still limited to experimentation and prototyping of 3D printed soft robotics, additive manufacturing could ultimately be used for the end-use and production of soft robotics.
Originality/value
The paper provides the current trend of how 3D printing techniques and materials are used particularly in the soft robotics application. The potentials of 3D printing technology on the soft robotic applications and the future outlooks of 3D printed soft robotics are also presented.

Abstract
Purpose
The purpose of this paper is to evaluate the impact of delivering healthy eating messages through an interactive health corner (HC) on improving healthy dietary habits in participants.
Design/methodology/approach
Self-administered questionnaires were administered to participants after the education session. In total, 5,292 valid questionnaires were obtained, yielding a response rate of 93.3 per cent. In the last three months of the pilot study, a random sample of 305 from 1,493 participants was chosen and followed up six months later. Bivariate analysis was used to study the association of knowledge gained and attitude. Behavioural change was measured in terms of whether participants had reported an increase in their consumption of healthier food.
Findings
Majority (>98 per cent) of participants reported that the HC corner was useful, and had helped increase their awareness and knowledge of creating healthier meals and making healthier food choices. 95.7 per cent were willing to make changes after visiting the HC. At six months follow-up, 84 per cent of the participants reported positive changes in their dietary habits. Those who made positive changes were younger (mean age: 58.0 years) compared with those who did not (mean age 61.0 years, p=0.035).
Research limitations/implications
Incorporating cooking demonstrations as part of nutrition education is effective in inculcating healthy eating practices and changing self-reported eating habits in the short term. Further research is needed to verify actual change in eating habits and to determine if this change is sustainable in the long run.
Originality/value
Currently, no similar initiative has been implemented and studied to evaluate the effectiveness of this mode of health promotion in a primary care setting. This study will help the authors to evaluate if the intervention was effective in changing attitudes and behaviours after an education session at the HC.
