BACKGROUND: The results of urine tests are often affected by improper midstream urine collection time, urine spilling, and urine pollution, all of which can lead to an increase in the test error.OBJECTIVE: To solve this problem, aiming at improving the toilet environment at the hospitals and public physical examination centers, this paper designs an automatic urine collection system. It can automatically adjust the position of the urine cup with an infrared remote controller, or manually, adjust the position of the urine cup in special situations according to the needs of the user. It also has an alarm function.METHODS: The overall size and shape are designed based on the squatting pan, suitable for disposable plastic urine cups of different shapes and sizes. It can realize the automatic collection of midstream urine, manual collection in exceptional cases, emergency stops, and rescue calls.RESULTS: Through the trial survey, there was a significant difference between the statistical results of using the device and not using the device ( 13.937, 0.000). 96% of the subjects thought that the design of the system was reasonable, 22% thought that it was inconvenient to use, and 91.7% of the medical staff thought that the system met the sampling requirements.CONCLUSIONS: Therefore, the trial evaluation is satisfactory, and the proposed collection system is suitable for use in hospitals at all levels and public health examination centers with a large amount of inspection.

Roadways worldwide are moving towards digitisation to enhance their operations; one of these operations is Toll tax collection, which can be digitised to reduce the time consumption in the traditional Toll tax collection System. One of the challenges for the digitisation of Toll tax collection is data integration and security. The blockchain technology used in this project ensures data integration and security. This paper proposed the design and implementation of the Automatic Vehicle Toll Collection System. The system enables the Toll tax collection authority to collect toll tax by tracking the travel journey of vehicles and eliminating the traditional method of managing tax in physical Toll booths, which is time-consuming and expensive to maintain. The system utilises Ethereum smart contracts during registration to ensure the smooth processing of the tax generation process. Every Vehicle integrates with an in-vehicle unit that uses a GPS device to acquire the Vehicle’s current position and final destination. Moreover, the proposed model incorporates micro-transactions through an off-chain payment system. The entire model is free from the scalability issues of on-chain blockchain transactions, Such as Flood and loot attacks. It provides the blockchain transaction finality time $\Delta$. The proposed theorems ensure security; the results demonstrate the correct functioning and reduced response time of smart contracts.

BACKGROUND:Chemotherapy is a complex, multi-disciplinary, and error-prone process. Information technology is being increasingly used in different health care settings with complex work procedures such as cancer care to enhance the quality and safety of care. In this study, we aimed to develop a computerized physician order entry (CPOE) for chemotherapy prescribing in patients with gastric cancer and to evaluate the impact of CPOE on medication errors and order problems.MATERIALS AND METHODS:A multi-disciplinary team consisting of a chemotherapy council group and system design and implementation team was formed for chemotherapy process evaluation, requirement analysis, developing computer-based protocols, and implementation of CPOE. A before and after study was conducted to evaluate the impact of CPOE on the chemotherapy process and medication errors and problem orders. To evaluate the level of end-user satisfaction, an ISO Norm 9241/110 usability questionnaire was chosen for the evaluation.RESULTS:Before the implementation of the CPOE system, 37 medication errors (46.25%) and 53 problem orders (66.25%) were recorded for 80 paper-based chemotherapy prescriptions. After implementation of the CPOE system, 7 (8.7%) medication errors and 6 (7.5%) problem orders were recorded for 80 CPOE prescriptions. The implementation of CPOE reduced the medication error by 37.55% and the problematic order by 58.75%. The results for usability evaluation indicate that the CPOE was within the first class of the ISONORM level rating; this shows that a CPOE is with very high satisfaction and a very high functionality rate.CONCLUSION:Developing a CPOE system significantly improved safety and quality of the chemotherapy process in cancer care settings by reducing the medication error, deleting unnecessary steps, improving communication and coordination between providers, and use of updated evidence-based medicine in direct chemotherapy orders. However, the CPOE system does not prevent all medication errors and may cause new errors. These errors can be human-related factors or associated with the design and implementation of the systems.

Follow-up evaluations or studies of teacher education programs are based on the premise that teacher training produces competencies, defined as program objectives, that can be observed in the behaviors of teacher education graduates. Effective follow-up begins with the design and implementation of systems that provide accurate information regarding the graduates’ behaviors. Effective systems provide timely, adequate, and appropriate feedback to program faculty and administrators. It is crucial to note that effective follow-up studies involve more than just the design of data collection systems. Follow-up evaluation is NOT research—at least according to the traditional meaning of the term research (Sommer, 1977). True, the conduct of a follow-up study incorporates research techniques, but it also includes a set of additional processes and procedures that are not required when engaging in research. An effective follow-up study requires an understanding of: The social context in which the follow-up is being conducted, The purposes associated with the follow-up evaluation, and The manner in which the follow-up evaluation data will be used.

<strong class="journal-contentHeaderColor">Abstract.</strong> An optimization framework for simultaneous design of wind turbines (WTs) and cable layout for a collection system of offshore wind farms (OWFs) is presented in this paper. The typical approach used in both research and practical design is sequential, with an initial annual energy production (AEP) maximization, followed then by the collection system design. The sequential approach is robust and effective. However it fails to exploit the synergies between optimization blocks. Intuitively, one of the strongest trade-offs is between the WTs and cable layout, as they generally compete; i.e. spreading out WTs mitigates wake losses for larger AEP but also results in longer submarine cables in the collection system and higher costs. The proposed optimization framework implements a gradient-free optimization algorithm to smartly move the WTs within the project area subject to minimum distance constraint, while a fast heuristic algorithm is called in every function evaluation in order to calculate a cost estimation of the cable layout. In a final stage, a refined cable layout design is obtained by iteratively solving a mixed integer linear programme (MILP), modelling all typical engineering constraints of this particular problem. A comprehensive performance analysis of the cost estimation from the fast heuristic algorithm with respect to the exact model is carried out. The applicability of the method is illustrated through a large-scale real-world case study. Results shows that (i) the quality of the cable layout estimation is strongly dependent on the separation between WTs, where dense WT layouts present better performance parameters in terms of error, correlation, and computing time, and (ii) the proposed simultaneous design approach provides up to 6 % of improvement on the quality of fully feasible wind farm designs, and broadly, a statistically significant enhancement is ensured in spite of the stochasticity of the optimization algorithm.

India is one of the leading producers of neem in the world. But still, there is no mechanical system available for either harvesting the neem fruits from the tree or collecting the neem fruits from the ground. Also, the manual ground collection of neem fruit is a very laborious and time-consuming operation. The cost of ground collection of neem fruit is higher than its selling price which makes neem plantation uneconomical. The introduction of a collection system for collecting the neem fruit from the ground may represent the technological change that is the key factor for improved competitiveness. The main purpose of this work was to develop ground collection system based on the principle of suction. The design of the machinery was based on a determination of fruit geometry and its physical and engineering properties. The proposed innovation enabled a fully mechanical solution for collecting the fallen neem fruit from the ground, achieving a collection capacity of approximately 10 kg.h-1 with a collection efficiency of over 90%.
