Game interventions have been demonstrated to have significant effects in terms of increasing treatment adherence and accessibility in the health profession. The use of game has a great therapeutic influence on the experience when doing recovery workouts. Due to its strengths, a game-based intervention model for elderly with memory disorder is proposed. The proposed model consists of both exogenous and instantaneous factors as its main components. Nine exogenous factors are attitude, emotion, skill, belief; support, attractive, fun, reminiscence, complexity. Six instantaneous factors are perceived focus, enjoyment, motivation, comfortability, perceived control, and boredom. To ensure its correctness, verification procedure has been carried out by using an expert review approach involving five experts from three different domains. Qualitative and quantitative feedbacks from the experts are used in refining the proposed model. Our works can be extended by incorporating other related theories to strengthen the model such as reminiscence and flow theories. The improved model is significant in providing a guideline of game-based intervention to other related domains. Our works are believed as effective in improving cognition among elderly, the interesting and positive findings can be attributed to the integration of digital game and psychotherapy for elderly, particularly those with memory disorder symptoms.

Bone loss is risen due to fractures, surgeries and traumatic injuries. Scientists and engineers work over the years to find solutions to heal and accelerate bone regeneration. Bone grafting technique has been utilised which projects significant improvement in bone regeneration area. An extensive study is essential on the relation between the mechanical properties of bone scaffolds and the design of bone scaffolds in forecasting permeability access to promote bone growth and nutrient distribution. In reducing cost and time, mechanical simulation analyses are beneficial to simulate the relation. There are abundant of review works on the mechanical simulation analyses towards orthopaedic metallic implants. While the review on simulation analyses towards bone scaffolds are scarce. Therefore, this review study is intended to expose the utilisation of computer simulation analysis, specifically Solidworks® software in modelling three-dimensional (3D) scaffold models, performing mechanical simulation and analysing bone scaffold structure. The data were collected from three main sources of Google search, Scopus search and Science Direct search. From this review procedure, there are various computational software have been combined and used to perform several types of simulation analyses on bone scaffolds including Solidwork, Ansys, Abaqus, COMSOL Multiphysics, MATLAB etc. Among the simulation analyses, two main tests that can be simulated are mechanical test and fluid modelling. Solidwork® as one of the computer-aided design softwares has been extensively used to design two and 3D models. The advancement of this software on the performance of mechanical simulation analyses has also extended its application towards variety of applications including on bone scaffold evaluation. There are several parameters which are necessary to be set prior to the conduction of mechanical simulation analysis such as applied forces, material properties, mesh properties and boundary condition. As a conclusion, Solidwork® software is applicable to be used as a 3D modelling software to design bone scaffolds and to perform mechanical simulation analyses.

Human skeletal system provides the protection of all organs and supports the loads from various daily activities. Therefore, the main objective of bone scaffold is to have mechanical strength to support the load and have the permeability that will have mass fluid transfer to enhance the healing of defects. In this study, we simulated the permeability of hexagonal unit cells at different pore sizes (1.0 mm, 1.5 mm and 2.0 mm) and at different inlet velocities (0.001 mm/s, 0.5 mm/s and 1 mm/s) by using Computational Fluid Dynamic (CFD) in Ansys software. Our finding shows that pressure drop from inlet to the outlet of the unit cell’s pore increased corresponding to the decreasing of pores diameter. In contrast, increasing the velocities has increased the pressure drop from inlet to the outlet. The pressure drop at 0.001 mm/s, 0.5 mm/s and 1mm/s inlet velocities were 1.40×10-4 Pa, 7.02×10-2 Pa and 1.41×10-1 Pa, respectively for 1.0 mm pore size. The gradual decreased of the pressure will give the cell and nutrient to be diffused to the inner part of the scaffold. We calculated the permeability for each unit cell, and it can be acceptable based on the upper limit of human bone permeability. The variation in velocities did not gave significant differences for the scaffold permeability. However, the different of pore sizes gave significant effect in the scaffold permeability. The permeability value at 0.001 mm/s for 1.0 mm, 1.5 mm and 2.0 mm pore size were 2.900×10-8 m2, 4.863×10-8 m2 and 8.529×10-8 m2, respectively. By taking into accounts the pressure drop and permeability value, unit cell with 1 mm pore size is predicted to show a better performance in promoting cell growth due to the better flow characteristics in the scaffold. Permeability prediction will help in producing a functional bone scaffold that crucial in bone regeneration of the human skeletal system.

This review was performed to determine the objective of therapeutic intervention on the learning of autistic children. This literature review aimed at addressing two critical issues: (1) the benefits of aromatherapy oils, including the understanding of its effect on ASD children in literature, and (2) the significance of its effect on their learning. An extensive search was carried out on various online databases, including ERIC, ProQuest Education Journals, and Scopus using the following phrases: (“aromatherapy oils” or “aromatherapy oils in learning”) and (“ASD children”). The studies selected for this review examined therapeutic interventions to improve the learning of autistic children and were analyzed using the content analysis method. Despite appeals for further studies in the 1980 and 1990s, no scientific evidence is available to substantiate the use of aromatherapy oils for learning. Although there are increased studies on aromatherapy oils, the impact on learning, especially for ASD children, has not been investigated. Furthermore, the methodological details on the use of aromatherapy oils in education remain poor. This study demonstrated that traditional methods for treating people with autism are not the only approach and that there is an alternative method using essential oils that is both healthy and toxic-free. The efficiency of basic oil was refuted, and clear evidence of essential oil benefits for people with autism understand was presented. This study would be of great interest to parties including parents of autistic children and organizations that assist people with autism.

For socially intelligent agents to become a fully digital therapist to support individual with mental health problem in the future, they need to know how to socially interact with humans. One of the key ingredients to allow this skill to take place is an ability to exhibit empathic behaviours. Despite a number of socially intelligent agents were build with empathic behaviour, they only cover single empathy behaviour, contrary to more complex triadic empathic behaviours. In this article, the conceptual design and model to implement triadic empathy in socially intelligent agents is presented.

Lung cancer is the prevalent cause of death among people around the world. The detection of the existence of lung cancer can be performed in a variety of ways, such as magnetic resonance imaging (MRI), radiography, and computed tomography (CT). Such techniques take up a lot of time and financial resources. Nevertheless, for the detection of lung cancer, CT provides a lower cost, fast imaging time, and increased availability. Early diagnosis of lung cancer may help physicians treat patients to minimize the number of deaths. This paper revolves around the categorization of lung cancer stages from CT scan images using image processing and k-Nearest Neighbor. The central objective of this study is therefore to establish an image processing technique for extracting features of lung cancer from CT scan images. Extracting the features from the segmented image can help to detect cancer inside the lung. The purposed method comprises the following steps by using image processing techniques: data collection, data pre-processing, features selection, and lung cancer classification. The pre-processing was done using a median filter to remove noise contained in the images. Three features need to be extracted which are area, perimeter, and centroid. Finally, the set of data with these features were used as inputs for lung cancer classification. By analysis results, the kNN method has a high accuracy of 98.15%.

Aloe vera is a well-known succulent plant and it is often used to moisturise and sooth the skin. In this study, Aloe vera is incorporated into natural soap to investigate the antibacterial properties and cytotoxicity of the samples. The antibacterial properties of the Aloe vera sample was determined by performing zone inhibition and bacterial colony test on Escherichia coli (E. coli). The cell viability test was conducted with human skin fibroblast cells through MTT assay. The Aloe vera samples showed antibacterial properties through the presence of inhibition zones and in the bacterial colony analysis, the Aloe vera samples have inhibitory effect against E. coli with a bacterial retardation percentage of 31.97±0.90%. The cell viability percentage of 95.30±11.16% was found on the Aloe vera sample with normal cell morphology. These results testified that the Aloe vera sample was biocompatible and possessed antibacterial properties which is suitable to be incorporated in skin products.

Coronary heart disease (CHD) is classified as the heart abnormality aside from myocardial damage which results in the blockage of coronary arteries which supply blood to the heart. In this study, a degradable vascular graft was developed to overcome the complications that associated with CHD. The degradable graft was fabricated in a structure of electrospun membranes using polyurethane (PU) matrix blended with chitosan (CS). The degradation analyses were performed through an immersion procedure by conducting the weight loss measurement and the element release test. The blending of PU with CS resulted in the increment of membrane degradability. The CS elements were released from the PU/CS membranes following the Higuchi model release mechanism. As a conclusion, the PU/CS membranes possess the degradable properties which might serve as a plausible candidate for the development of vascular graft for repairing cardiac damage.

Mobile phone applications are so entwined in modern culture and are continuously accessible to users as they could be beneficial as mobile coaching systems. The goal of this research is to employ mobile application software to guide horse riders in conditioning their horses to optimal performance and to emphasize the need of using appropriate and accurate equipment. The theory of app development of the app will be using ADDIE model. The process of creating this mobile app will be undergoing five different phases of Analysis, Design, Development, Implementation and Evaluation. A sample of 40 respondents had been given free access to use and try the mobile application before a System Usability Scale (SUS) test was given. Results from the five positive-preferred SUS components had obtained a range of mean from 4.30 to 4.60, which are very close to the ideal of 5.00. The range of standard deviation also shows better whereby the range are between 0.54948 to 0.91147 which are under common ideal practice which is 1.10. The results obtained show that the users were satisfied and the usability of the mobile application was good, up to 82.5% of the respondents were interested to install the mobile application, and positive feedbacks were also recorded. These results show that people are ready and willing to use the mobile application as an alternative way to an accessible horse exercise options and horse training programs in easier way.
