Acetabular defects, Hip arthroplasty, Rapid prototyping, Revision, Surgical procedure design, Orthopedic surgery, and RD701-811
Objective To compare rapid prototyping technology (RP tech) in revision total hip arthroplasty (RTHA) with traditional examination methods and to see how they are different in evaluating acetabular anatomy and designing surgical procedure. Methods From February 2014 to March 2018, 43 RTHA patients with complex acetabulum defects were enrolled in this prospective study regardless of age or gender. Incomplete and unclear data were excluded. Three types of radiographic examination were performed on each patient before the revision surgery. Four groups of evaluations were designed: (i) X‐ray; (ii) computed tomography (CT‐scan); (iii) RP tech; and (iv) CT‐aided RP tech. Discrepancies between preoperative radiographic analysis and intra‐operative findings were separately compared by a team of surgeons. Premade surgical plans based on each evaluation method were compared with the final surgical procedure. The compliance of anatomic evaluation and surgical plan‐design based on 3D RP tech and traditional radiographs were ranked manually by a of team surgeons into: (i) complete accordance; (ii) general accordance; and (iii) undetermined structure/procedure. The difference in ranks between RP tech and traditional radiographic methods were analyzed with a nonparametric Kruskal‐Wallis test. P

At present, speed is a key factor in the design and development of industrial products, And In the light of modern technology, computer-based prototyping techniques have emerged in so-called advanced rapid prototyping as a solution to the modeling activity associated with design processes. But these technologies have disadvantages, such as the high cost of the models and the long time it takes for these models to be completed, The subject of the research came to the virtual prototyping as a modern technology through which the models associated with the design activity of industrial products, These models provide the speed required in light of the continuous evolution and changing requirements of the market, and also provide a low-cost solution suitable for adoption by major companies or small and medium-sized enterprises alike. The importance of these virtual models is evident when it comes to communicating as much information about design as possible with the simplest way and the lowest costs, Through these models can include everything related to the product of work theories and engineering drawings and three-dimensional models with physical properties that mimic the final product, Within the same application and this information induced by one of the images prepared on the computer programs, and thus we can share these models over the Internet and work on them remotely, which in turn contributes to shorten the time of the design process. The importance of research is to shed light on the role of virtual prototyping as one of the basic elements in the process of design and development of industrial products, as the research aims to activate the role of virtual modeling in the process of product design and development and to include them in the design process as one of the basic stages' because of its usefulness, The hypothesis is that if virtual prototyping techniques and new technologies can be utilized in the process of designing industrial products in a creative manner, this ensures that the cost of model design and testing processes is reduced, as well as the opportunity to develop products periodically without incurring many expenses related to the production of physical models. The deductive approach was used to achieve this.

fast-prototyping, ibm watson, iot, mqtt, node-red, raspberry pi, smart home, telegram, Computer software, and QA76.75-76.765
The Internet of Things has contributed to make smarter houses and buildings in the last decades. Different existing works already integrate IoT technologies in homes, but end-user needs continuously change and researchers must face this challenge in identifying platforms to fast prototype solutions satisfying these new needs. This paper presents a solution that demonstrates how well-known fast-prototyping technologies like Node-RED, IBM Watson, Telegram, Raspberry Pi 4, and secured MQTT can contribute to develop complex systems facing the challenge. The selected tools are used within a smart home context to support features inspired by people needs and allow users to: a) consult real time conditions (i.e., temperature, humidity, gas), b) remotely manage lights, c) save energy through a light management system based on user movements, d) remotely monitor the house through dedicated webcams, e) generate warning notifications in case of danger. Users can interact with the systems through a web Node-RED dashboard and a Telegram bot. Differently from existing works, the feasibility of the implemented system and the efficacy of the exploited platforms are demonstrated through a running scenario extracted from a consolidated study on user needs in smart homes. The performed experiment can facilitate the fast prototyping of new solutions.

The increasing number of road accidents and deaths among children in Malaysia is a concern. One of the main causes stems from lack of knowledge and skills in dealing with the complexity and condition of the road system. Recognizing the significance of road safety among students, road safety education has been introduced to primary schoolsby the Ministry of Education in 2008. Initially it was blended into the Malay language subject with the goal to equip the children withthe knowledge and skills about road safety.However, road safety teaching and learning still uses the conventional methods without the use of specialized tools. This paper introduces ROSE courseware, a specialized learning tool developed to meet the needs of the Malaysian primary school curriculum for road safety education. Its learning environment is a blend of virtual reality, augmented reality and interactive multimedia, which enables children to understand and acquire skills related to road safety through interactive, real-time and immersive learning tool. In order to receive the children’s feedbacks pertaining to their experience in interacting with the ROSE courseware, a usability evaluation was conducted. The results show that the children strongly agreed on the usefulness, information quality and interface quality of the ROSE courseware.
