Laser scanning does not provide unlimited geometrical accuracy and integrity when scanning complex objects. Scanning systems have a minimum and maximum range in which they operate, depending on the technical characteristics. Scanning below or above these limits results in gross errors and registering of incorrect data. Laser scanners can have difficulties with certain materials such as marble and reflective surfaces. This paper presents the results of laser scanning of a complex monument of cultural and historical heritage using two different types of terrestrial laser scanners. Afterwards, the comparison and analysis of the results are shown. The scanners used were terrestrial laser scanners Faro Focus 3D (phase mode distance measurements) and STONEX X300 (pulse mode distance measurements).

Introduction: Dry needling is a therapeutic procedure using the insertion of thin needles through the skin into myofascial trigger points (MTrPs), muscular or connective tissue with the aim to reduce pain intensity. The objective of this systematic review is to analyze the literature for the efficacy of the dry needle technique in pain reduction in conditions of musculoskeletal pain caused by MTrPs. Reference Sources: Web of Science, Scopus and EBSCOhost database were searched for studies and e-books published from January 2010 to December 2018. Studies Selection: We included randomized controlled studies, prospective and longitudinal studies, and case studies which analyzed the efficacy of dry needling for musculoskeletal pain reduction. Data Extraction Method: The studies, which satisfied criteria for inclusion were further analyzed. The primary instrument of the evaluation was pain intensity analyses. Results: Dry needling treatment is efficient in pain intensity reduction in patients who suffer musculoskeletal pain and is more efficient compared to sham dry needling treatment. In addition, different techniques of dry needling are efficient in the treatment of myofascial pain syndrome. Conclusion: Based on systematic review of the literature, dry needling, independently or as an addition to other intervention, is recommended for treatment of musculoskeletal pain conditions caused by myofascial trigger points. Various techniques of dry needling treatment are almost equally efficient in myofascial pain intensity reduction.

3D geological models can be very useful in many geological, mining and other engineering activities. Constructed model should serve as a 3D geodatabase for variety of input data. Study area represents one of the bauxite bearing sites, Crvene Stijene, near Jajce (Bosnia & Herzegovina). Presented methodology includes the integration, digitalization, organisation and visualisation of different types of input data (600 boreholes, geological maps and sections, DEM, structural measurements from the surface and in the tunnels and adits) in the 3D geological database. In the modeling workflow, different types of geological objects were modeled with different interpolation algorithms. Used interpolation algorithm depends on complexity of geological object, character and spatial distribution of input data. The model is interactive which is important because there are constantly ongoing research and exploitation activities: boreholes, underground mining objects, etc. that can be easily imported into the model. 3D geological model represents a basis for planning new scientific research and mining activity.

Flail chest, often defined as the fracture of three or more ribs in two or more places, represents the most severe form of rib fractures. Conservative treatment, consisting of respiratory assistance with endotracheal intubation and mechanical ventilation (internal pneumatic stabilization) and pain control, are the current treatments of choice in the majority of patients with multiple rib fractures. However, the use of mechanical ventilation may create complications. In selected patients, operative fixation of fractured ribs within 72 h post injury may lead to better outcomes. We conducted a retrospective analysis of a series of nine cases of patients who developed flail chest after blunt trauma, and were treated with surgical osteofixation of the chest wall and postoperative epidural analgesia at the University Clinical Center of the Republic of Srpska during the period from January 2015. to December 2016. Two patients had trauma to the chest only, and the other patients had associated injuries to the head, abdomen, spine, and fractures of the pelvis and long bones. In the majority of patients (77.7%), surgical stabilization of the chest was performed on the second day following the injury, (mean, 2.33 days) and no later than 5 days after the injury. All patients received epidural analgesia with 0, 25% bupivacaine and 0, 01% morphine and intravenous multimodal analgesia, beginning 6 h after thoracotomy. The average length of ICU stay was 14.7 days (range 2–36), while the average number of days of mechanical ventilation was 8.1. The average duration of hospitalization was 25.4 days. Tracheotomy was performed in 33.3% of study patients. Mortality in the observed group was 44.4%. This study shows that surgical stabilization and epidural analgesia reduced ventilator support, shortened trauma intensive care unit stay, and reduced medical costs vs internal pneumatic stabilization.

: In the last ten years, digital technology has significantly contributed to the change of people's lives worldwide, because its application has caused a rapid transformation of all aspects of human life, and especially fast transformation in the design, production, operation and maintenance of the production system, which caused an unexpected jump in productivity. It can be said that fourth industrial revolutions on-going process, which can be labelled a variety of ways, such as "intelligent factory", "smart industry" or "advance manufacturing". Development of the digital technologies in the last twenty years has introduced us from third in the fourth industrial revolution. The first time the term “Industry 4.0” appears in the Germany in year 2011 whose government promotes automation of production processes by introducing digital technologies. Germany is one of the most technologically developed countries in the world and it is logic that this revolution begins there. This example follows the other countries in the world. Fourth technological revolution depends on a number of new and innovative technological achievements. It is necessary to integrate production processes in all production phases and further applications by using ICT technologies for digitalization. The automation of production processes must include advanced sensors and intelligent robots that can be self-configured to be able to make specific product. It is necessary to collect large amounts of data to be analysed and used in the production processes.

Two interesting and rarely occurring species of fungi from the order Pezizales found in Bosnia and Herzegovinaare presented here. Ecology, morphology, microscopic characters and conservation status of Pezizamontirivicola and Trichophaea flavobrunnea are briefly discussed in the paper. Notes on the similar speciesof operculate discomycetes are given.
