Abstract The vibration produced by road traffic can contribute to the long-term adverse effects on heritage structures. The objectives of this study were to analyze the dynamic response of the heritage building under time-dependent loads caused by traffic vibration by carried out the transient analysis in ANSYS and to determine the level of Vibration Criterion of the heritage building due to traffic vibration by using VSATs in MATLAB software. This research was to predict the traffic vibration effect on the old building of Telecom Muar at Johor, Malaysia. A field testing was carried out using a mobile application, iDynamics, to obtain the vibration signal induced by road traffic. The data obtained were analyzed using ANSYS and MATLAB software. Two types of analysis were carried out using ANSYS, which are modal analysis and transient analysis. MATLAB was used to obtain the vibration criteria plot (VC) for the building. The natural frequency of the fundamental mode shape was 2.57Hz. The natural frequency of the building is acceptable as it is below the human sensitivity frequency range. On the other hand, the level of vibration criteria of the building falls on VC-E, which is the lowest level in the Generic Vibration Criteria Plot implemented by Gordon (1991). In conclusion, both natural frequency and the vibration criteria of the selected building is acceptable according to the results obtained from the analysis conducted.

Abstract Aim: With increasing demands on the healthcare system, a central (and currently essential) push for remote consultations, and an increasing number of co morbidities in the surgical population, the aim was to create an application that placed the focus on pre-hospital optimisation, education and autonomy – addressing these sector trends to enhance outcomes for patients and ease the burden on healthcare settings. Method After obtaining baseline data, I worked alongside students from the Queensland University of Technology to produce an application suitable for both iOS and android platforms. Results The application has four facets which mirror a patient’s journey from their initial outpatient appointment through to recovery. The application is easy to use, free to download and readily accessible. On opening the application, the user can select their planned operation and navigate along a personalised decision tree. Conclusions The application has been designed to educate and empower a patient to become an active participant in their care, leading to long-term changes in healthcare. Assessment is ongoing but early indications suggest that this will be a valuable tool in optimising outcomes for patients undergoing vascular surgery – leading to fewer post-operative complications and earlier restoration of functional status.

Over 50% of road traffic injury (RTI) patients experience post-traumatic acute lung injury (ALI) and it is, therefore, extremely important to identify the risk factors related to the poor outcomes associated with ALI in RTI populations. This study evaluated 19 potential risk factors associated with the outcomes of ALI in 366 RTI patients. They were divided into two groups: a ‘favourable outcomes group’ and an ‘unfavourable outcomes group’. The results indicated that the Acute Physiology and Chronic Health Evaluation II (APACHE II) score and the presence of gastrointestinal haemorrhage may help predict the outcomes of ALI in the early post-trauma phase of treatment. The duration of trauma and sepsis were shown to impact strongly on both the short- and long-term outcomes of ALI. Age (≥ 65 years) and disseminated intravascular coagulation in the early RTI phase were also independent risk factors for a poorer short- and long-term outcome in ALI.

The results of lengthy thorough investigations into traffic safety situation show that the percentage of pedestrians getting involved in road traffic accidents on Lithuanian roads is significantly higher (more than 33 % of the total number of injury and fatal accidents) than that compared to the other European Union member-states. The article studies traffic safety problems and their factors causing the largest influence on the occurrence of these accidents. Considering valuable experience gained by foreign countries, investigation was carried out to establish general and main factors causing insufficient road safety conditions and significance of these factors to road safety. The article also shows the main activity improving road safety in Lithuania and discusses the effectiveness of strategic and local (temporary and long term) measures to improve conditions for pedestrian road safety.

Complex transportation systems often produce combined exposure to aircraft and road noise. Depending on the noise source, the annoyance response is different, and a masking effect occurs between the noise sources within the combined noise. Considering these characteristics, partial loudness was adopted to evaluate noise annoyance. First, a partial loudness model incorporating binaural inhibition was proposed and validated. Second, short- and long-term annoyance models were developed using partial loudness. Finally, the annoyance of combined noise was visualized as a map. These models can evaluate the annoyance by considering both the intensity and frequency characteristics of the noise. In addition, it is possible to quantify the masking effect that occurs between noise sources. Combined noise annoyance maps depict the degree of annoyance of residents and show the background noise effect, which is not seen on general noise maps.
