We present a novel approach for decreasing state uncertainty in planning prior to solving the planning problem. This is done by making predictions about the state based on currently known information, using machine learning techniques. For domains where uncertainty is high, we define an active learning process for identifying which information, once sensed, will best improve the accuracy of predictions. We demonstrate that an agent is able to solve problems with uncertainties in the state with less planning effort compared to standard planning techniques. Moreover, agents can solve problems for which they could not find valid plans without using predictions. Experimental results also demonstrate that using our active learning process for identifying information to be sensed leads to gathering information that improves the prediction process.

Sand flies (Diptera: Psychodidae) are medically important vectors of human and veterinary disease-causing agents. Among these, the genus Leishmania (Kinetoplastida: Trypanosomatidae), and phleboviruses are of utmost importance. Despite such significance, updated information about sand fly fauna is missing for Balkan countries where both sand flies and autochtonous leishmaniases are historically present and recently re-emerging. Therefore, a review of historical data on sand fly species composition and distribution in the region was followed by a large-scale entomological survey in eight Balkan countries to provide a recent update on local sand fly fauna. The literature search involved the period 1910–2019. The entomological survey was conducted at 1189 sampling stations in eight countries (Bulgaria, Bosnia and Herzegovina, Croatia, Kosovo, Montenegro, North Macedonia, Serbia and Slovenia), covering 49 settlements and 358 sampling sites between June and October in the years 2014 and 2016, accumulating 130 sampling days. We performed a total of 1189 trapping nights at these stations using two types of traps (light and CO2 attraction traps) in each location. Sampling was performed with a minimal duration of 6 (Montenegro) and a maximal of 47 days (Serbia) between 0–1000 m.a.s.l. Collected sand flies were morphologically identified. In total, 8490 sand fly specimens were collected. Morphological identification showed presence of 14 species belonging to genera Phlebotomus and Sergentomyia. Historical data were critically reviewed and updated with our recent findings. Six species were identified in Bosnia and Herzegovina (2 new records), 5 in Montenegro (2 new records), 5 in Croatia (2 new records), 9 in Bulgaria (5 new records), 11 in North Macedonia (1 new record), 10 in Serbia (no new records), 9 in Kosovo (3 new records) and 4 in Slovenia (no new records). This study presents results of the first integrated sand fly fauna survey of such scale for the Balkan region, providing first data on sand fly populations for four countries in the study area and presenting new species records for six countries and updated species lists for all surveyed countries. Our findings demonstrate presence of proven and suspected vectors of several Leishmania species.

The aim of this paper is to demonstrate how the correct application of FEM analysis can be used to find effective solutions for the design of mechanical structures. The design of the inspection openings on the tanks is being considered. There are several existing tanks of the same dimensions (20 m high and diameter 10,2 m), but they have different wall thicknesses (9,6; 15; 20 and 25 mm). For inspection purposes, assembly of manhole hatch on all tanks is required. The manhole hatch is designed applying standard API 650. All tanks are filled with the water to the top 20 m high. Several different analyses have been carried out in order to ensure that there are not too high stresses in the materials of the existing tanks due to the insertion of the manhole hatch and finally qualify construction according to EN-13445 norm. The elastic analysis shows that stresses in the material are too high and the design hasn’t been approved. In order to avoid redesign procedures, which can be expensive and sometimes difficult to do in reality, plastic analysis has been done. After plastic analysis, the design could be approved with the restriction on the max. preload force in the bolts 40 kN/per bolt.

The aim of the study was to determine the psychological characteristics of mothers of children with cerebral palsy. The study included a sample of 30 respondents. The sample consisted of mothers of children with cerebral palsy, chronologically aged 25 to 60. The research was conducted at the Centre for Children with Multiple Disabilities “Koraci Nade”. For the purpose of checking the set research aim, Symptom ChecklistSCL-90-R, consisting of a list of 90 particles (problems), was applied, and the task was to assess the respondent's anxiety about each of the aforementioned problems over the past week (e.g., headaches, tension or anxiety, excessive worrying). The survey data were processed using the parametric statistics method. Central tendency measures, dispersion measures were calculated, and a tabular presentation of the results was done. Based on the results of the research, it can be concluded that the mothers of children with cerebral palsy have the most pronounced problems in areas of somatization, depression, obsessive-compulsive disorders, as well as anxiety.

Background COVID-19 pandemic presented an unexpected challenge for the surgical community in general and Minimally Invasive Surgery (MIS) specialists in particular. This document aims to summarize recent evidence and experts’ opinion and formulate recommendations to guide the surgical community on how to best organize the recovery plan for surgical activity across different sub-specialities after the COVID-19 pandemic. Methods Recommendations were developed through a Delphi process for establishment of expert consensus. Domain topics were formulated and subsequently subdivided into questions pertinent to different surgical specialities following the COVID-19 crisis. Sixty-five experts from 24 countries, representing the entire EAES board, were invited. Fifty clinicians and six engineers accepted the invitation and drafted statements based on specific key questions. Anonymous voting on the statements was performed until consensus was achieved, defined by at least 70% agreement. Results A total of 92 consensus statements were formulated with regard to safe resumption of surgery across eight domains, addressing general surgery, upper GI, lower GI, bariatrics, endocrine, HPB, abdominal wall and technology/research. The statements addressed elective and emergency services across all subspecialties with specific attention to the role of MIS during the recovery plan. Eighty-four of the statements were approved during the first round of Delphi voting (91.3%) and another 8 during the following round after substantial modification, resulting in a 100% consensus. Conclusion The recommendations formulated by the EAES board establish a framework for resumption of surgery following COVID-19 pandemic with particular focus on the role of MIS across surgical specialities. The statements have the potential for wide application in the clinical setting, education activities and research work across different healthcare systems.

School in the modern society should provide an environment for students to feel safe and motivated for learning. There should be an optimal student workload with the schoolwork as well as with the homework. Unfortunately, student overload at all levels of education has been evident. Their overloaded schedule presents a significant challenge and may cause fatigue, exhaustion, distraction, mope, high levels of stress, apathy, superficially and campaign learning, and general lack of motivation. Due to the topicality of the issue, the authors of this paper have tried to offer a review of the sources of the student overload. Different sources, as well as negative consequences of student overload have been determined based on a significant number of empirical works so far. The article also suggests measures to relieve students. Psychologists, in cooperation with the students’ parents and experts from other branches of the education sector, can contribute in finding a way to prevent and reduce consequences of the overload. Empirical studies about sources of student overload are also necessary to determine evidence based guidelines for the education reform.

Inclusion should be an important value of every society. Education institutions are the place for developing universal values that should enable every individual to express their needs in a unique and different way, which will prompt an inclusive environment that values diversity. Forming an inclusive environment fosters opportunity for developing creativity. Although inclusive education and creativity are rarely perceived as related, this paper aims to present the values and creativity opportunities of inclusive education. A chorus of criticism directed at the education system shows that creativity is not recognized enough, especially when it comes to students with disabilities whose creativity is often not seen as one of their abilities, even when it is developed. That happens as a result of perceiving the students through the prism of their disability. The emphasis should be on developing the values during the preschool period, which is the most significant period of a child’s development as that is the time when the foundations of the personality development are set. The subject of this research is focused on identifying the values and creativity opportunities of inclusive education, while the intention is to recognize the possible ways of developing creativity in an inclusive environment. The aim of the research was to examine the educators’ opinions on values and creativity opportunities of inclusion. As of recently, preschool institutions have been now facing an increasing number of children with disabilities enrolling in. Therefore, new challenges are posed on the preschool education when it comes to providing the children with the conditions for a development that meets their needs and abilities. The purpose of the paper is to offer strategies that will ensure the development of core values while respecting the creative potential of each child in an inclusive environment.

Book Review: Bakšić, Sabina, Bulić, Halid, 2019. Pragmatika. Sarajevo: Bookline.

In the present paper, the authors analyse attitudes of students (N=91) studying at the Department of English Language and Literature toward distance learning launched at the Faculty of Philosophy, University of Sarajevo, during the COVID-19 pandemic in March 2020. The study is designed as action research containing elements of both qualitative and quantitative research. The key instrument for collecting data was a survey designed by the authors of the present paper. The Google Forms survey was delivered to 1st-5th year students at the Department of English Language and Literature by e-mail. The collected data were processed by means of SPSS software (descriptive statistics). Results of the analysis show that students do not consider “distance learning’’ to be of better quality when compared to “learning in the classroom’’ but also that students, in the period of returning to a “new normal’’, openly express their preference for blended learning. At the same time, results of the analysis reveal that it is necessary to modernise teaching practices by means of introducing a more representative version of the distance learning system that would not only significantly improve the quality of the teaching practices, but also assist in maintaining competitiveness of the Faculty of Philosophy as a higher education institution.

Acinar cystic transformation (ACT) or acinar cell cystadenoma is a rare benign tumor of the pancreas. Their clinical presentation is nonspecific, thus hampering their detection and frequently leading to misdiagnosis. In this report, we present a case of ACT of the pancreas in a 54-year-old man that was vague abdominal symptoms. A magnetic resonance imaging was shown a well-defined cystic mass located in the head of the pancreas, measuring 57×47×23 mm. Our patient was treated by pancreaticoduodenectomy. In the macroscopic examination of the mass, a multicystic lesion was found in cream-colored pancreatic tissue. Histological and immunohistochemical studies examination revealed a cystic mass containing multiple cysts at varying sizes, lined by epithelial cells without atypia and positive staining of CK7, CK8/18, and CK19. A high index of clinical suspicion is required to diagnose this tumor. The surgical approach is to ensure accurate diagnosis and to avoid complications

Plitvice Lakes National Park is the largest national park in Croatia and also the oldest from 1949. It was added to the UNESCO World Natural Heritage List in 1979, due to the unique physicochemical and biological conditions that have led to the creation of 16 named and several smaller unnamed lakes, which are cascading one into the next. Previous scientific research proved that the increased amount of dissolved organic matter (pollution) stops the travertine processes on Plitvice Lakes. Therefore, this complex, dynamic but also fragile geological, biological and hydrological system required a comprehensive limnological survey. Thirteen of the sixteen lakes mentioned above were initially surveyed from the air by an unmanned aircraft equipped with a survey grade GNSS and a full frame high-resolution full-screen camera. From these recordings, a georeferenced, high-resolution orthophoto was generated, on which the following surveys by a multibeam sonar depended. It is important to mention that this was the first time that these lakes had ever been surveyed both with the multibeam sonar technique and with such a high-resolution camera. Due to the fact that these thirteen lakes are difficult to reach and often too shallow for a boat-mounted sonar, a special autonomous surface vehicle was developed. The lakes were surveyed by the autonomous surface vehicle mounted with a multibeam sonar to create detailed bathymetric models of the lakes. The missions were planned for the surface vehicle based on the orthophoto from the preliminary studies. A detailed description of the methodology used to survey the different lakes is given here. In addition, the resulting high-resolution bathymetric maps are presented and analysed together with an overview of average, maximum depths and number of data points. Numerous interesting depressions, which are phenomena consistent with previous studies of Plitvice Lakes, are noted at the lake beds and their causes are discussed. This study shows the huge potential of remote sensing technologies integrated into autonomous vehicles in terms of much faster surveys, several orders of magnitude more data points (compared to manual surveys of a few decades ago), as well as data accuracy, precision and georeferencing.

Selection of Sustainable Suppliers is a key term in sustainable supply chain management. This is the reason to choose the supplier who will support the company to implement sustainability in its business, especially in the supply chain. The aim of this paper is to establish a new innovative model for decision-making based on a fuzzy approach. This decision-making problem is solved by applying multi-criteria decision-making since there are several criteria according to which a decision should be made: economic, social, and environmental. In order to make the final decision on the supply chain better and safer, the social criteria were modified in this paper, adding ethical criteria. The example with modified social criteria in this paper was shown on the example of the company "Voćar" Brčko, which deals with the production of food products. In this paper, the fuzzy Measurement Alternatives and Ranking, according to the Compromise Solution Method, was used. The findings have shown that supplier A1 has the best results, which were confirmed with the first sensitivity analysis. However, the second sensitivity analysis has shown that supplier A5 was better than supplier A1 in 14 scenarios. Due to these findings, no unanimous decision can be made about which supplier among the two, in this case, would contribute more. This paper has shown that the selection of sustainable suppliers is crucial for any company focused on the principles of sustainability in business. Moreover, this paper has shown that it is sometimes very difficult to select just one supplier.

Public servants responsiveness and administrative responsibilities to their constituents in local communities are identified through the set of ethical standards predominantly resulting in good governance. Some researchers and practitioners in the field of integrity and ethics concur with the premise of administrative responsibility and responsiveness operating under holistic approaches to understanding climate resilience. This analysis contends with the traditional views of the theory of social choice and administrative burden to stipulate a suitable ethical framework and understanding of ethics in considering climate resilience. The research takes into consideration the principles and structure of moral expectations and measurable outcomes related to climate resilience through the Quadruple Bottom Line lens. The good governance in resilience is explored using an exploratory data analysis of local governments through resilience planning supported by the Rockefeller Foundation, which funded 100 Resilient Cities initiative. The sample size consisted of thirty cities with the obtainable resilience or climate actions plans and a review of their governance efforts through those documents and detailed plans. The research offers a preliminary report of the ongoing efforts in cities and regions to combat climate change, coupled with the ethical considerations and administrative responsibility to frame the administrators’ role in deliberation to climate resilience. The research findings assert a prototype ethical framework for review by administrators to augment administrative responsiveness to climate change threats and increase climate resilience.
