Abstract
Purpose
Fingerprints and blood samples are important for the identification of individuals and criminals. The present study aims to identify the predominant fingerprint patterns and the association between the fingerprint patterns and ABO–Rh blood groups in Omani population.
Design/methodology/approach
A cross-sectional study was conducted on 200 Omani individuals aged 18 years (104 males and 96 females). The imprints of all right and left-hand fingers were taken, and the types of the fingerprints were determined using a standard protocol. The blood group of all the subjects was recorded. Chi-square test was performed to identify the association between the fingerprint patterns and the ABO and Rh blood groups.
Findings
The loop fingerprint pattern was the most common in Omani subjects (49.4%), followed by whorl (44.9%) and arch (5.7%) pattern. A significant association (p < 0.001) was found between gender and fingerprint pattern. The loop was the highest occurring pattern in the females (54.6%), while the whorl was more in males (50.0%). The whorl pattern was the most common in the AB+ and O− groups. The loop was a predominant pattern in the A+, A−, B+, B− and O+ groups. The Chi-square test also revealed a significant correlation between different fingerprint patterns and blood groups of the subjects (p < 0.001).
Originality/value
The present study is an outcome of undergraduate student's research project thesis for the Doctor of Medicine (MD) program. The results of the present study may help in creating a data bank for biometrics, which can be useful for diagnosing associated diseases and also help in identification of individuals.

Abstract
In order to be able to use the aroma hand massage as a skill that can be done by a nurse who does not have a special aromatherapy technique, we examine anti-stress effects of simplified aroma hand massage for healthy subjects. We evaluated the anti-stress action of aroma hand massage and the different components of the procedure in 20 healthy women in their twenties. We used autonomic nervous function measured via electrocardiogram as an index of stress. After conducting a baseline electrocardiogram, we induced stress in the participants by asking them to spend 30 minutes completing Kraepelin's arithmetic test. We then administered various treatments and examined the anti-stress effects. Kraepelin's test significantly increased sympathetic nervous function and significantly reduced parasympathetic nervous function. Compared with massage without essential oil or aroma inhalation, aroma hand massage significantly increased parasympathetic nervous function and significantly decreased sympathetic nervous function. The effect of the aroma hand massage persisted when the procedure was simplified. The anti-stress action of the aroma hand massage indicates that it might have beneficial application as a nursing technique. There are several limitations in this study; ambiguities of low component/high component ratio of heart rate variability and bias by small subjects groups of the same women.

Abstract
Purpose
It is generally accepted that massage can provide a lot of benefits to human health, especially for the brain functions. Little is known about the effect of unilateral massage on the brain activities. Nowadays, Swedish massage is a modern massage technique that is popular in both treatment and research fields. The purpose of this paper is to investigate the effect of unilateral Swedish massage on brain activities with electroencephalography (EEG) recording.
Design/methodology/approach
In total, 18 healthy adult participants (5 men, 13 women) aged between 22 and 36 years were massaged over one side of arm, forearm, hand, neck and face. Then the same procedures were repeated to another side of the body. EEG was recorded before (baseline) and during each massage condition. The absolute power of four common brain waves consisting of δ (0.5-4 Hz), θ (4-8 Hz), α (8-13 Hz), and β activities (13-30 Hz) from the quantitative EEG analysis between baseline and each massage condition were used to compare with the paired t-test.
Findings
The study found the reduction of δ and θ powers over bilateral frontal, fronto-central, and central areas. The increments of α power over the similar brain areas were also observed. These findings indicated the generalized effect of unilateral Swedish massage for inducing relaxation. Moreover, the significant reduction of β power was also found over right central area when left-arm massage was applied. This finding revealed the initial inhibitory effect of Swedish massage over right somatosensory cortex that received sensory stimulation through massage from left side of the body.
Originality/value
Unilateral Swedish massage induced the inhibitory effect at the contralateral somatosensory cortex and then produced the generalized effect which is compatible with relaxation.

Abstract
Purpose
The purpose of this paper is to unveil the intricacies of bakat art of weaving; its origin; processes; uses; primary materials and principles used; the profile of the weavers; and its economic significations in the system of production and trade.
Design/methodology/approach
The study used a descriptive–qualitative design with 35 key informants using narrative analysis. The unstructured questions listed in the interview guide were used during the interview. Responses were recorded using an audio–video recorder. Coding sheets were used in the actual transcription of data.
Findings
The results showed dependency on the bakat art of weaving with the available resources found in the environment. Its economic significations showed a sustainable impact on the weavers’ life. The bakat art of weaving represented the values of resiliency to hardships, adaptability to changes, passion to craftsmanship, sense of community and family centeredness. Aspiring craftsmen and artists may enhance continuously their craftsmanship for sustainable development with government support through the creation of the School of Living Traditions.
Research limitations/implications
The study was limited to bakat art of weaving based on the responses of the key informants that were subjected to a point of saturation without sacrificing robustness, brevity, credibility and dependability.
Practical implications
Though the economic side of bakat art of weaving is sustainable within the village, it can create a powerful branding for cultural recognition that would transform the town of Barili into a creative weaving hub in Cebu. This creates the balance of the historical significance of bakat art of weaving and the tourism sector in promoting sustainable development.
Social implications
Bakat art rekindled the spirit of consciousness among the majority of the Cebuano public for preservation and promotion.
Originality/value
The study is original because this has not been published.

Abstract
Cornelia de Lange syndrome (CdLS) is a congenital disorder characterized by distinctive facial features, growth retardation, limb abnormalities, intellectual disability, and behavioral problems. Cornelia de Lange syndrome is associated with abnormalities on chromosomes 5, 10 and X. Heterozygous point mutations in three genes (NIPBL, SMC3 and SMC1A), are responsible for approximately 50-60% of CdLS cases. CdLS is characterized by autistic features, notably excessive repetitive behaviors and expressive language deficits. The prevalence of autism spectrum disorder (ASD) symptomatology is comparatively high in CdLS. However, the profile and developmental trajectories of these ASD characteristics are potentially different to those observed in individuals with idiopathic ASD. A significantly higher prevalence of self-injury are evident in CdLS. Self-injury was associated with repetitive and impulsive behavior. This study describes the behavioral phenotype of four children with Cornelia de Lange syndrome and ASDs and rehabilitative intervention that must be implemented.

Abstract
Purpose
This study aims to provide an exploratory analysis of the role of virtual reality (VR) in the cruise context as a contribution to the limited literature on this topic. In particular, the research investigates immersive VR as a critical touchpoint at the pre-purchase stage of the customer journey.
Design/methodology/approach
To achieve the research aims, the authors use a case study approach by analysing the “immersive configurator” (essentially a virtual catalogue) implemented by the Mediterranean Shipping Company (MSC).
Findings
Three innovative functions emerged from the study of the MSC’s virtual catalogue. First, it improves the customer experience and engagement through its interactivity. Second, it allows customization of the prospective cruise experience by selecting and changing types of ship, the level of service, the position of the cabin and much more. Third, it becomes a new digital marketing system endowed with large amounts of data.
Research limitations/implications
This study advances the current state of knowledge by presenting an empirical case study on the role of immersive VR at the pre-purchase stage of the customer journey. Second, it offers interesting implications for managers who want to take advantage of the opportunities offered by VR.
Originality/value
The present study analyses the pre-purchase stage in tourism marketing focused on the use of VR in the tourist experience at the time of service delivery. Second, it enriches the tourism literature by integrating supply-side and demand-side perspectives. Third, from a methodological point of view, this paper offers an in-depth qualitative study in a context where scholars have mostly applied quantitative methods.

Abstract
Purpose
In recent years, there has been significant interest in adopting XR (extended reality) technologies such as VR (virtual reality) and AR (augmented reality), particularly in retail. However, extending activities through reality-mediation is still mostly believed to offer an inferior experience due to their shortcomings in usability, wearability, graphical fidelity, etc. This study aims to address the research gap by experimentally examining the acceptance of metaverse shopping.
Design/methodology/approach
This study conducts a 2 (VR: with vs. without) × 2 (AR: with vs. without) between-subjects laboratory experiment involving 157 participants in simulated daily shopping environments. This study builds a physical brick-and-mortar store at the campus and stocked it with approximately 600 products with accompanying product information and pricing. The XR devices and a 3D laser scanner were used in constructing the three XR shopping conditions.
Findings
Results indicate that XR can offer an experience comparable to, or even surpassing, traditional shopping in terms of its instrumental and hedonic aspects, regardless of a slightly reduced perception of usability. AR negatively affected perceived ease of use, while VR significantly increased perceived enjoyment. It is surprising that the lower perceived ease of use appeared to be disconnected from the attitude toward metaverse shopping.
Originality/value
This study provides important experimental evidence on the acceptance of XR shopping, and the finding that low perceived ease of use may not always be detrimental adds to the theory of technology adoption as a whole. Additionally, it provides an important reference point for future randomized controlled studies exploring the effects of technology on adoption.
