    BACKGROUND: An isolated robot must take account of uncertainty in its world model and adapt its activities to take into account such as uncertainty. In the same way, a robot interaction with security and privacy issues (RISAPI) with people has to account for its confusion about the human internal state, as well as how this state will shift as humans respond to the robot.

    OBJECTIVES: This paper discusses RISAPI of our original work in the field, which shows how probabilistic planning and system theory algorithms in workplace robotic systems that work with people can allow for that reasoning using a security robot system. The problem is a general way as an incomplete knowledge 2-player game.

    RESULTS: In this general framework, the various hypotheses and these contribute to thrilling and complex robot behavior through real-time interaction, which transforms actual human subjects into a spectrum of production systems, robots, and care facilities.

    CONCLUSION: The models of the internal human situation, in which robots can be designed efficiently, are limited, and achieve optimal computational intractability in large, high-dimensional spaces. To achieve this, versatile, lightweight portrayals of the human inner state and modern algorithms offer great hope for reasoning.

    Adolescence is the developmental process of becoming an adult. This journey of physical and psychological maturation is filled with challenges and hormonal chaos, and teenagers experience unhappiness at times. From a psychological perspective, this study aimed to examine the association between motivation, self-esteem and happiness; and to explore the mediating role of motivation in the association between self-esteem and happiness among adolescents in Malaysia. 480 secondary school students were recruited using a multistage cluster sampling method and answered the Malay versions of the Subjective Happiness, Brief Motivation and Rosenberg Self-esteem scales. Both self-esteem and motivation were found positively correlated to happiness. The hypothetical mediating role of motivation on the association between self-esteem and happiness was also supported, indicating that individuals with higher self-esteem have higher motivation which may result in greater happiness. Since the direct association between self-esteem and happiness remained significant, a partial mediation of adolescents' motivation between self-esteem and happiness is indicated. The results showed that perceived self-esteem plays a role in predicting happiness and the presence of motivation enhances happiness, providing an insight to nurture happier adolescents for parents and educators in Malaysia.

    Keyword extraction is essential in determining influenced keywords from huge documents as the research repositories are becoming massive in volume day by day. The research community is drowning in data and starving for information. The keywords are the words that describe the theme of the whole document in a precise way by consisting of just a few words. Furthermore, many state-of-the-art approaches are available for keyword extraction from a huge collection of documents and are classified into three types, the statistical approaches, machine learning, and graph-based methods. The machine learning approaches require a large training dataset that needs to be developed manually by domain experts, which sometimes is difficult to produce while determining influenced keywords. However, this research focused on enhancing state-of-the-art graph-based methods to extract keywords when the training dataset is unavailable. This research first converted the handcrafted dataset, collected from impact factor journals into n-grams combinations, ranging from unigram to pentagram and also enhanced traditional graph-based approaches. The experiment was conducted on a handcrafted dataset, and all methods were applied on it. Domain experts performed the user study to evaluate the results. The results were observed from every method and were evaluated with the user study using precision, recall and f-measure as evaluation matrices. The results showed that the proposed method (FNG-IE) performed well and scored near the machine learning approaches score.

    Despite the benefits of standardization, the customization of Software as a Service (SaaS) application is also essential because of the many unique requirements of customers. This study, therefore, focuses on the development of a valid and reliable software customization model for SaaS quality that consists of (1) generic software customization types and a list of common practices for each customization type in the SaaS multi-tenant context, and (2) key quality attributes of SaaS applications associated with customization. The study was divided into three phases: the conceptualization of the model, analysis of its validity using SaaS academic-derived expertise, and evaluation of its reliability by submitting it to an internal consistency reliability test conducted by software-engineer researchers. The model was initially devised based on six customization approaches, 46 customization practices, and 13 quality attributes in the SaaS multi-tenant context. Subsequently, its content was validated over two rounds of testing after which one approach and 14 practices were removed and 20 practices were reformulated. The internal consistency reliability study was thereafter conducted by 34 software engineer researchers. All constructs of the content-validated model were found to be reliable in this study. The final version of the model consists of 6 constructs and 44 items. These six constructs and their associated items are as follows: (1) Configuration (eight items), (2) Composition (four items), (3) Extension (six items), 4) Integration (eight items), (5) Modification (five items), and (6) SaaS quality (13 items). The results of the study may contribute to enhancing the capability of empirically analyzing the impact of software customization on SaaS quality by benefiting from all resultant constructs and items.

    The COVID-19 pandemic at the beginning of 2020 has changed the conventional learning mode for most students at schools all over the world, and the e-learning at home has become a new trend. Taking Chinese college students as the research subject and drawing on the stimulus-organism-response (S-O-R) model, this paper examines the relationship between the peer referent, perceived closeness, and perceived control and the learning engagement. Using data from 377 college students who have used e-learning, this study shows that perceived closeness, perceived control, and peer referents in e-learning have a positive effect on the self-efficacy and well-being of students, thus improving students' enthusiasm for learning. Our intent is to assist researchers, instructors, designers, and others in identifying effective methods to conceptualize and measure student engagement in e-learning.

    The lack of aesthetic properties of electrospun nanofibres in terms of colour appearance is the drive in this preliminary study. This research is conducted to study the dyeing behaviour and colorimetric properties of electrospun nanofibres blended with Remazol Yellow FG reactive dye using dope-dyeing method via electrospinning process. This paper reports the colorimetric properties of dyed poly vinyl alcohol (PVA) nanofibres within the range of 2.5 wt.% to 12.5 wt.% dye content. The electrospinning parameters were fixed at the electrospinning distance of 10 cm, constant feed rate of 0.5 mL/h and applied voltage of 15 kV. The resulting impregnated dye of 10 wt.% exhibits acceptable colour difference of dyed PVA nanofibres, with a mean fibre diameter of 177.1 ± 11.5 nm. The SEM micrographs show the effect of dye content on morphology and fibre diameter upon the increment of dye used. Further increase of dye content adversely affects the jet stability during the electrospinning, resulting in macroscopic dropping phenomenon. The presence of all prominent peaks of Remazol dye in the PVA nanofibers was supported with FTIR analysis. The addition of dye into the nanofibres has resulted in the enhancement of thermal stability of the PVA as demonstrated by TGA analysis.

    Higher education policy and talent training are failing to meet the ever-changing expectations of employers and society in Taiwan, resulting in a gap between university education and employment. This study used social cognitive career theory (SCCT) to explore the relationships among self-efficacy, transformational leadership (TL), student employability (SE), and problem-based learning (PBL) in higher education institutions (HEIs). The analysis of 637 undergraduates from 16 Taiwanese HEIs using structural equation modeling (SEM) shows significant positive correlations among self-efficacy, PBL, TL, and SE, with PBL and self-efficacy as key mediators. Based on these findings, the researchers propose feasible suggestions for related issues and future research.

    Introduction: The burden of untreated postoperative pain is high.

    Objective: This study assessed feasibility of using quality improvement (QI) tools to improve management of perioperative pain in hospitals in multiple developing countries.

    Methods: The International Pain Registry and Developing Countries working groups, from the International Association for the Study of Pain (IASP), sponsored the project and PAIN OUT, a QI and research network, coordinated it, and provided the research tools. The IASP published a call about the project on its website. Principal investigators (PIs) were responsible for implementing a preintervention and postintervention study in 1 to 2 surgical wards in their hospitals, and they were free to choose the QI intervention. Trained surveyors used standardized and validated web-based tools for collecting findings about perioperative pain management and patient reported outcomes (PROs). Four processes and PROs, independent of surgery type, assessed effectiveness of the interventions.

    Results: Forty-three providers responded to the call; 13 applications were selected; and PIs from 8 hospitals, in 14 wards, in 7 countries, completed the study. Interventions focused on teaching providers about pain management. Processes improved in 35% and PROs in 37.5% of wards.

    Conclusions: The project proved useful on multiple levels. It offered PIs a framework and tools to perform QI work and findings to present to colleagues and administration. Management practices and PROs improved on some wards. Interpretation of change proved complex, site-dependent, and related to multiple factors. PAIN OUT gained experience coordinating a multicentre, international QI project. The IASP promoted research, education, and QI work.

    Psychological literature on race has discussed in depth how racial identities are dialogically constructed and context dependent. However, racial identity construction is often not compared across different socio-political contexts. By researching racial identity construction in three different multicultural countries, Malaysia, Singapore, and the United Kingdom, we examined how three racial identities, Chinese, Malay, and Indian, are constructed among Malaysians and Singaporeans in this qualitative study comprised of 10 focus group discussions (N = 39). We applied Dialogical Analysis to the data. This paper shows that both racial ingroups and outgroups constructed all three racial identities, with ingroups constructing their identities more heterogeneously compared to outgroups. Participants also engaged with colonial constructions of the three racial identities. The geographical locations, and therefore their perceptual contexts, of the participants differed. Yet, colonial constructions of race endured in contemporary identity construction and were contested in the group settings. We conclude that the socio-political context as understood by the context of colonialism and post-coloniality influenced their racial identity constructions. Participants, regardless of differences in geographical location, used similar colonial constructions of Malay, Chinese, and Indian identities to position themselves as well as Others in their group interactions. These findings show that there is value in conceptualising the context beyond that which individuals are immediately presented with, and that psychologists should consider the inclusion of cultural legacies of colonialism in their conceptualisation of the present context.

    Introduction: Caring for those with dementia affects the quality of life for both the caregivers and the patients themselves, particularly in the informal care system here in Malaysia. To date, only a few studies have explored from the family caregivers’ perspectives in the communities of different cultural background. The purpose of this study is to describe the Malaysian family caregivers’ perspectives of their experiences in providing care to for their family members suffering from moderate to severe dementia in Kuala Lumpur, Malaysia. Methods: This qualitative study involved in-depth individual interviews with twelve caregivers to patients with moderate to severe dementia. Participants were recruited via purposive sampling from the outpatient psycho-geriatric clinic at UKM Medical Centre, Kuala Lumpur. All interviews were audio-recorded and transcribed verbatim. Transcribed data was later analysed using a thematic approach. Results: Four themes identified in this study were; i) the feeling that ‘it is like caring for a baby’, ii) the caregivers’ perception of inadequate knowledge and skills, iii) the need for caregivers’ support system and iv) the importance of spirituality in enhancing care giving experiences. Conclusions: The framework of care shared by the caregivers in this study demonstrated strong cultural and spirituality influences in addition to the common issues of the challenges in managing the behavioural and psychological symptoms in people with dementia. Hence, culture and spirituality aspects should be addressed in the development of appropriate intervention to manage the needs of informal caregivers in this community.

    In this work, we proposed a facile approach to fabricate a superhydrophobic surface for anti-icing performance in terms of adhesive strength and freezing time. A hierarchical structure was generated on as-received Al plates using a wet etching method and followed with a low energy chemical compound coating. Surfaces after treatment exhibited the great water repellent properties with a high contact angle and extremely low sliding angle. An anti-icing investigation was carried out by using a custom-built apparatus and demonstrated the expected low adhesion and freezing time for icephobic applications. In addition, we proposed a model for calculating the freezing time. The experimented results were compared with theoretical calculation and demonstrated the good agreement, illustrating the importance of theoretical contribution in design icephobic surfaces. Therefore, this study provides a guideline for the understanding of icing phenomena and designing of icephobic surfaces.

    PURPOSE: To explore the experiences and needs of parents while waiting for their children undergoing surgery.

    DESIGNS AND METHODS: A descriptive qualitative study was conducted. A purposive sample of 11 parents who went through their first waiting experiences during their children's surgeries in a Singapore public hospital was recruited. Children younger than or equal to 16 years of age were included. A semi-structured interview guide facilitated the individual face-to-face interviews. Thematic analysis was used.

    RESULTS: Four themes were identified: "Care and care provision affecting waiting experiences", "Parental concerns and surgery affecting waiting experiences", "Coping strategies used during waiting periods" and "Recommendations to improve waiting experiences". Pre-operative instructions, the professionalism of medical teams, and a lack of timely updates affected parental experiences. Parents expressed their worries. The complexities and types of surgery influenced how they felt. Their concerns included potential complications, surgical outcomes, anesthesia-related side effects, and post-operative care including pain. They spent their waiting times eating, resting, using their smart devices, and coping with a support system. Environmental improvements, more updates, and mobile applications were recommended by the participants.

    CONCLUSION: For a parent, the wait during his/her child's surgery can be unsettling. Our results give insights into parental waiting experiences and needs during their children's surgeries.

    PRACTICE IMPLICATIONS: These findings can guide the improvement of the current practise based on our evidence or the implementation of newer technology to provide better waiting experiences for parents during their children's surgeries and to enhance the quality of clients' experiences in the hospital.

    PROBLEM: Stigma affects not only children diagnosed with autism spectrum disorder (ASD) themselves, but also people connected with them (i.e., parents, siblings). The capacity of parents to provide care is affected by the stigma they perceive. This meta-synthesis encompasses the experiences of affiliate stigma among parents of children with ASD.

    ELIGIBILITY CRITERIA: Articles were limited to the English language, those reported on stigma experienced by parents of children with ASD aged 2-18 years, published between 1940 and 2019.

    SAMPLE: PubMed, CINAHL, PsycINFO, EMBASE, Scopus and The Cochrane Library databases were searched for eligible studies. Titles and abstracts were reviewed, and twelve articles fitted the selection criteria. The texts of the selected research papers were reviewed by two independent reviewers.

    RESULTS: Four common themes across parental experiences included felt stigma, enacted stigma, variations in stigma, and contributors to stigmatizing experiences.

    CONCLUSIONS: Highlighting the differences in parents' views on affiliate stigma is necessary to create awareness about ASD and the stigma linked with this disorder.

    IMPLICATIONS: The findings asserted that healthcare professionals, especially those in pediatric settings, and society need to have a greater awareness of the stigma and challenges that these parents encounter as this has implications on their mental and physical health. This awareness will lead to more compassionate health care delivery which will support them and create a better environment for families and children with ASD.

    Offretite zeolite synthesis in the presence of cetyltrimethylammonium bromide (CTABr) is reported. The offretite crystals were synthesized with a high crystallinity and hexagonal prismatic shape after only 72 h of hydrothermal treatment at 180 °C. The CTABr has dual-functions during the crystallization of offretite, viz. as structure-directing agent and as mesoporogen. The resulting offretite crystals, with a Si/Al ratio of 4.1, possess more acid sites than the conventional offretite due to their high crystallinity and hierarchical structure. The synthesized offretite is also more reactive than its conventional counterpart in the acylation of 2-methylfuran for biofuel production under non-microwave instant heating condition, giving 83.5% conversion with 100% selectivity to the desired product 2-acetyl-5-methylfuran. Hence, this amphiphile synthesis approach offers another cost-effective and alternative route for crystallizing zeolite materials that require expensive organic templates.

    Naturally active compounds are usually contained inside plants and materials thereof. Thus, the extraction of the active compounds from plants needs appropriate extraction methods. The commonly employed extraction methods are mostly based on solid-liquid extraction. Frequently used conventional extraction methods such as maceration, heat-assisted extraction, Soxhlet extraction, and hydrodistillation are often criticized for large solvent consumption and long extraction times. Therefore, many advanced extraction methods incorporating various technologies such as ultrasound, microwaves, high pressure, high voltage, enzyme hydrolysis, innovative solvent systems, adsorption, and mechanical forces have been studied. These advanced extraction methods are often better than conventional methods in terms of higher yields, higher selectivity, lower solvent consumption, shorter processing time, better energy efficiency, and potential to avoid organic solvents. They are usually designed to be greener, more sustainable, and environment friendly. In this review, we have critically described recently developed extraction methods pertaining to obtaining active compounds from plants and materials thereof. Main factors that affect the extraction performances are tuned, and extraction methods are chosen in line with the properties of targeted active compounds or the objectives of extraction. The review also highlights the advancements in extraction procedures by using combinations of extraction methods to obtain high overall yields or high purity extracts.

    When examining spontaneously recovered memories of childhood sexual abuse, victims report that there had been periods in which they had forgotten the abuse. However, there are sometimes people with whom the victim had spoken about the abuse during the period in which the victim had supposedly forgotten the abuse, suggesting the victim had not forgotten the abuse but the prior recall of the abuse. The underestimation of previous knowledge is termed the forgot-it-all-along effect. The goal of the present study was replicating the results of a laboratory study that had provided a theoretical understanding for the forgot-it-all-along effect by showing that people have difficulties remembering "remembering" when the memory had previously been recalled in a different context. The effect was replicated by using the same neutral context sentences, suggesting the finding was robust. We also extended the experimental design by using positive and negative context sentences, but it did not become smaller when the positive sentences provided the different context or larger when the negative sentences provided the different context. Although the sample sizes were sufficiently large to provide statistical power for the forgot-it-all-along effect, they may not have been sufficiently large to observe the moderation effects of emotional context.
