Sustainability in a supply chain is a demand on the one hand and a challenge on the other. It is necessary to balance between these dimensions in order to fulfill the purpose of the supply chain. Therefore, in the first phase—i.e., in procurement—it is necessary to take into account its sustainability. In this paper, a sustainable supplier was selected respecting all three aspects of sustainability. The evaluation was carried out on the basis of a total of 21 criteria arranged into two levels and three groups. A new Interval Rough SAW (simple additive weighting) method, which represents a contribution to the treatment of problems belonging to the multi-criteria decision-making (MCDM), was developed. The integration of interval rough numbers with the SAW method was completed. In addition, the full consistency method (FUCOM) was applied to determine the weights of the criteria. The integrated FUCOM-Interval Rough SAW model enables treatment of multi-criteria problems while reducing subjectivity to the lowest possible level and eliminating uncertainties and ambiguities. The results obtained were determined throughout a sensitivity analysis consisting of a change in the weight of the criteria and the influence of dynamic matrices on the change in ranks. In addition, Spearman’s rank correlation coefficient (SCC) was calculated to confirm the stability of the previously obtained results.

Radar sensors have been used for active safety in cars for many years. An ongoing research project explores how radar sensors and technology common in automotive vehicles can be transferred for use on bicycles. Workshops have been used to generate ideas. A bicycle simulator is planned to be used for test and evaluation. Tests on a test track has been used to simulate high-risk scenarios. This paper describes the design process of this project, with focus on the user interface. High-risk scenarios and requirements are identified, followed by identified design challenges and design activities, including evaluation. Ideas for a dual HMI approach, directed towards the bicyclist and towards surrounding traffic are presented.

Interactions between autonomous vehicles (AV) and pedestrians remain an ongoing area of research within the AutoUI community and beyond. Given the challenge of conducting studies to understand and prototype these interactions, we propose a combined full-day workshop and tutorial on how to conduct field experiments and controlled experiments using Wizard-of-Oz (WoZ) protocols. We will discuss strengths and weaknesses of these approaches based on practical experiences and describe challenges we have faced. After diving into the intricacies of different experiment designs, we will encourage participants to engage in hands-on exercises that will explore new ways to answer future research questions.

OBJECTIVES Cone beam computed tomography (CBCT) in dentistry and maxillofacial surgery is a widely used imaging method for the assessment of various maxillofacial and dental pathological conditions. The objective of this study was to summarize the results of a multinational retrospective-prospective study that focused on patient exposure in this modality. METHODS The study included 27 CBCT units and 325 adult and paediatric patients, in total. Data on patients, clinical indications, technical parameters of exposure, patient dose indicator, or, alternatively, dose to phantom were collected. The dose indicator used was air kerma-area product, PKA. RESULTS In most scanners operators are offered with a variety of options regarding technical parameters, especially the field-of-view (FOV) size. The median and the third quartile value of PKA for adult patients in 14 different facilities were 820 mGy cm² and 1000 mGy cm² (interquartile range, IQR = 1058 mGy cm²), and 653 mGy cm² and 740 mGy cm² (IQR = 1,179 mGy cm²) for children, as reported by four different institutions. Phantom dose data were reported from 15 institutions, and median PKA ranged from 125 mGy cm² to 1951 mGy cm². Median PKA values varied by more than a tenfold between institutions, mainly due to differences in imaging protocol used, in particular FOV and tube current-exposure time product. CONCLUSIONS The results emphasize the need for a cautious approach to using dental CBCT. Imaging only when the clinical indications are clear, accompanied with the appropriate radiographic techniques and the optimum imaging protocol, will help reduce radiation dose to patients.

Objective − To present a rare case of osteoid osteoma of the metacarpal bone and to emphasize the importance of correlation of radiological analysis with anamnestic data and clinical findings. Case Report − We reported the case of osteoid osteoma of the metacarpal bone in a 14-year old girl. The patient, a volleyball player, presented with pain in the left hand. At first, nonsteroidal anti-inflammatory drugs relieved the pain but over the time it became more intense and was accompanied with swelling. On the basis of magnetic resonance imaging (MRI), the case was misdiagnosed as a status post-fracture of three metacarpal bones. After inappropriate treatment with physical therapy, the patient’s condition worsened, thus multiple laboratory tests and radiology imaging techniques were performed to achieve the right diagnosis. Diagnosis of osteoid osteoma was finally made by CTscan and appropriate treatment by surgical ablation was performed. Conclusion − Osteoid osteoma rarely occurs in metacarpal bones. Physicians should be aware of the atypical clinical presentation of this benign lesion in the metacarpal bones.

Fault passage indicators (FPIs) and fault locators (FLs) are employed in modern distribution networks in order to enhance the process of fault localization, thus resulting in reduction of interruption time and improving the reliability of power supply. In this paper, a novel probabilistic techno-economic optimization method is proposed for determining the number and positions of FPIs that lead to maximum reduction of interruptiontime and investment costs in medium voltage (MV) distribution networks with and without FLs. The proposed method is basedon a probabilistic non-sequential Monte Carlo simulation model of the real network, which is a proper compromise between complicated sequential simulation models and too simplified analytical models. The main goal of the method is to obtain maximum improvement of the network reliability indices while using the minimum number of FPIs. The method is tested on a combinedurban/rural MV distribution network in Bosnia and Herzegovina and results are thoroughly discussed.

The aim of this review is to discuss the local experience of Tuzla’s hospital staff and the knowledge needed to become a Baby-Friendly Hospital (BFH). We also discuss the risks of formula feeding. While breast milk is the natural modality of infant feeding, in Tuzla Canton, the rate of exclusive breastfeeding in the first 6 months of life is only 12%. During the war of 1992-1995, which was the worst European atrocity since World War II and the worst set of events in the recent history of Bosnia-Herzegovina, we had the opportunity to learn more about the impact of breastfeeding on child health from Chloe Fisher, a renowned clinical specialist on infant feeding. The United Nation Children’s Fund (UNICEF) and the World Health Organisation (WHO) held several seminars, about recommended practices and procedures needed to become a BFH. As a result, the Maternity Hospital was certified as a BFH in 2004 and has been operating with this status since then. While our Maternity Hospital and other related departments provided services and care of infants, many infant formula companies donated milk and organized conferences and other paediatric events to promote infant formula. This and other obstacles resulted in the fact that currently only 3 out of 7 mothers in our neonatology department breastfeed, and only 1 baby out of 7 is exclusively breastfed. Conclusion – Transforming a hospital in Baby-Friendly means, amongst other things, all professionals must provide breastfeeding management to ensure a long-term breastfeeding policy. The current low breastfeeding rate in our hospitals is the result of inconsistent policies in achieving long-term goals in breastfeeding practices.

Building envelope has significant role in the building sector. It represents immediate interaction between outside and inside environment. In dependence of its characteristics and opposed requirements, it affects on achievement of the thermal comfort of inside area and closer environment. Existing standards in the building sector dictate air tightness of an envelope, limiting air infiltration with the aim to save energy, but also influence on the inside environmental quality in situation when optimal air quality cannot be achieved due to the insufficient ventilation of the room. Besides that, building envelope in dependence of its characteristics, under the influence of Sun light, can less or better absorb heat flux and cause the temperature rise on the surface of the building. Specific characteristic of material to absorb and retain solar thermal heat, in urban environments, contributes more and more to the presence of the phenomenon known as urban heat island. For interaction of the building envelope with the environment factors, the building of Mechanical Engineering Faculty was chosen as a case study, on which the measurement of the envelope surface temperature was performed with the aim to empirically confirm presence of higher temperatures on building envelope. At the same time, the measurement of indoor air quality parameters, as carbon dioxide concentration, inside air temperature and relative humidity was performed, to estimate ventilation efficiency of inside area. Results of the measurement have shown the presence of relatively high surface temperature on the building envelope, which is the in accordance with the earlier research about the existence of higher surface temperatures in dependence of its characteristics and environment. Measurement of indoor air quality parameters showed higher carbon dioxide concentrations, especially in winter semester, which values exceeded by 60 % of recommended ones. Higher carbon dioxide concentrations are result of insufficient ventilation of the room, and it is indicator that optimal cooling system with frequent ventilation is necessary criteria that needs to be fulfilled to achieve quality inside environment from the aspect of the comfort, productivity and health of users. In the recent years, there has been noticed evident increase of the outside temperature, especially in urban area due to the construction and characteristics of applied materials in buildings, resulting also in the climate change. It is necessary to emphasize that planners and designers in the conceptual stage of construction or renovation of the buildings, incorporate solutions and decisions about the materialization of the envelope, which will affect on the reduction of urban heat island, considering as one of the energy efficiency measures.
