Semiotics:Semantic model-driven development for IoT interoperability of emergency services

Modern early warning systems (EWSs) use Internet-of-Things (IoT) technologies to realize real-time data acquisition, risk detection and message brokering between data sources and warnings' destinations. Interoperability is crucial for effective EWSs, enabling the integration of components and the interworking with other EWSs. IoT technologies potentially improve the EWS efficiency and effectiveness, but this potential can only be exploited if interoperability challenges are properly addressed. The three main challenges for interoperability are: (1) achieving semantic integration of a variety of data sources and different representations; (2) supporting time- and safety-critical applications with performance and scalability; and (3) providing data analysis for effective responses with personalized information requirements. In this paper, we describe the “SEmantic Model-driven development for IoT Interoperability of emergenCy serviceS” (SEMIoTICS) framework, which supports the development of semantic interoperable IoT EWSs. The framework has been validated with a pilot performed with accident use cases at the port of Valencia. The validation results show that it fulfils the requirements that we derived from the challenges above.</p

Fracture of the posterior malleolus: an underdiagnosed condition

The ankle joint is the most commonly injured joint during sports activity. While ankle sprains occur more frequently, ankle fractures are less common. Due to its low incidence, the isolated fracture of the posterior malleolus still represents a diagnosis challenge. This article reports a case of a female with a posterior malleolus isolated fracture after falling while performing sports activity. Clinical examination and conventional radiography were consistent with diagnosis of a simple ankle sprain and the patient was discharged with a conservative approach for lateral ankle sprain. Due to persistent pain the patient return for additional examination, which the differential diagnosis revealed an isolated fracture of the posterior malleolus without displacement of the fragment. The patient was immobilized with a suropodalic splint for 4 weeks followed by additional conservative. At the fourth month of follow-up, the patient was asymptomatic and showed good clinical and functional outcomes. This case highlights the importance of a comprehensive medical history and detailed clinical examination which may reveal pathological features that require a differential diagnosis

Tibial tunnel positioning on lateral radiographs in anterior cruciate ligament reconstruction: a single surgeon experience

Background: Accurate tunnel positioning in anterior cruciate ligament reconstruction surgery is one of the cornerstones for its success. However, it is still controversial and target of disagreement within the orthopedic literature. Therefore, it was aimed to evaluate the tibial tunnel placement in anterior cruciate ligament reconstruction surgeries of a single orthopedic surgeon.Methods: The postoperative knee sagittal radiographs of anterior cruciate ligament reconstructed knees from a single surgeon were retrospectively collected. To assess the tunnel positions was used predefined criteria (in percentage and in millimeters) within the intervals found in the literature (41-43 percent and 21-23 millimeters).Results: There were no significant differences between the number of results (% and mm), within and without the intervals that were considered acceptable for this measure (P &gt;0.05). It was found significant differences in the absolute deviation (%) throughout non-consecutive years (P &lt;0.05). There was no correlation between the absolute deviations and the years of experience (r =-0.080, P =0.663).Conclusions: Significant differences were found in the absolute deviation (%) throughout non-consecutive years, suggesting variations in the tunnel position throughout the years.

Preface to the fourth international workshop on models and model-driven methods for service engineering - 3M4SE 2013

The Fourth International Workshop on Models and Model-driven Methods for Service Engineering -3M4SE 2013- aims at helping the convergence of research on model-driven development and practical application of the model-driven approach in the area of enterprise computing and service engineering. The workshop addresses questions with respect to the requirements on, concepts for, properties of and experience with models and model-driven methods for service engineering in the area of enterprise computing. A special focus has been on the combined application of model-driven and semantic approaches in the different phases of the service lifecycle
