Surface Integration

According to the sequential surface integration process hypothesis, the fine near-ground-surface representation and the homogeneous ground surface play a vital role in the representation of the ground surface. When an occluding box or opaque wall is placed between observers and targets, observers underestimate egocentric distance. However, in our daily life, many obstacles are perforated and cover the ground surface and targets simultaneously (e.g., fences). Humans see and observe through fences. The images of these fences and targets, projected onto observers’ retinas, overlap each other. This study aims to explore the effects of perforated obstacles (i.e., fences) on space perception. The results showed that observers underestimated the egocentric distances when there was a fence on the ground surface relative to the no-fence condition, and the effect of widely spaced thick wood fences was larger than that of narrowly spaced thin iron fences. We further demonstrated that this effect was quite robust when the target size had a visual angle of 1°, 2°, or 4° in three virtual reality experiments. This study may add support for the notion that the sequential surface integration process hypothesis is applicable even if the obstacle is perforated and covers the target.

Fatwa is an explanation on Islamic ruling, which is needed by local society in facing new issues, as a solution in accordance with Shariah. It also plays a vital role to clarify the confusions and misunderstandings that happen in Muslim community. The solutions offered by Fatwa would satisfy the curiosity and internal feeling of Muslim in their daily life. This article will discuss the concept of fatwa and the challenges of its enforcement according to ‘The Administration of Islamic Law (Federal Territory) Act’. Besides, the writer would also identify the relevant authority body which has been given power by the aforementioned Act to enforce the issued fatwa. The article would try to reveal some problems and challenges in enforcing fatwa. Based on writer’s observation, the standard of fatwa enforcement in Federal Territory of Kuala Lumpur is still below the normal level as it should to be. The number of officer in the Enforcement Division of Islamic Department is inadequate to make the fatwa as effective law. Hopefully, this article would give a clear picture to Muslim community on the reality of Fatwa enforcement in Federal Territory of Kuala Lumpur.

Abstract Background: In western countries and China, back and neck pain has become a common problem that bothers daily life and severely influences the quality of our daily life. Among all factors that lead to chronic neck and back pain, IDD is the one that couldn’t be easily neglected. Methods: This study aims to figure out the critical genes and pathways involved in the development of IDD and provide a new aspect of following investigations on the etiology of IDD. We firstly systemically searched the GEO database and identified the differentially expressed genes (DEGs) from the expression profile dataset we selected. We secondly constructed the protein-protein interaction (PPI) network for DEGs, identified the top ten hub genes from the whole PPI network and found two statically and medically significant modules from the network, we then performed the GO and KEGG analysis on the DEGs, top ten hub genes, the PPI network and the two statically and medically modules. In the end, we provided the primers of the mRNAs of all DEGs, which will be useful for the validation experiment of this study. Results: FN1, MMP2, POSTN, COL3A1, TIMP3, FBN1, GJA1, TGFBI, EFEMP1 and ID1 were top ten hub genes identified from this study, and they may play a vital role in the development of IDD. Angiogenesis and integrin binging are crucial biological process and molecular function defined in this study, which are worthy of being intensely investigated.Conclusion: More studies on the top ten hub genes, the role of angiogenesis and integrin binding in IDD are urgently needed, which will benefit the prevention, screening, diagnosis and prognosis of IDD.

Mixed Approach

What if customer experience was the primary driver of digital transformation? Indeed, new hybrid experiences have emerged thanks to daily-life technologies that fused both digital and physical worlds. This kind of experience uses applications and connected objects (IoT) to adapt and respond to consumer needs. Augmented reality and virtual reality are one of the most functionally and emotionally memorable phygital experiences that create value for customers. In this chapter, the authors chose heritage tourism as the study field for different reasons. While the adoption of augmented and virtual reality is gaining grownd, cultural heritage sites have started to consider the possibilities offered by these new and innovative technologies. This industry is starting to integrate AR and VR in several ways to attract more people. However, it is necessary to study how modern technology can be developed and implemented in a meaningful way to improve the tourist's experience. An AR- and VR-based mobile application has been developed and tested at Antonine's Baths in Carthage, Tunisia.

This chapter is about a redesign of mental healthcare, as it evolves in a changing world. It focuses on digital transformations and their impact on social relationships, networks, and communities. It intends to demonstrate better responses to the needs of service users in society. It first defines terminologies to access the changing world and focus on how to understand health, recovery, and well-being in people with lived experience of psychosis. These central elements can be accessed or maintained using eHealth, including mHealth, virtual reality, and eCommunities. It also discuss strengths, challenges, and pitfalls in developing and applying innovative interventions in the context of daily life. It reviews these trends and how these relate to the therapeutic relationship in general, and the mental health practitioner’s role in particular.
