Authors: Ivetić Vojislav , Martinjak Špela , Maksuti Alem 
Published: December 2021

Abstract

Introduction
Primary care physicians use various tools and methods to identify medically unexplained symptoms (MUS). The main purpose of our study is to determine the views of Slovenian family medicine trainees (FMT) about using the “Careful Assessment” tool for managing patients with MUS.

Methods
A qualitative study using open survey questions focused on the experience of family medicine trainees in managing patients with MUS. The sample consisted of surveys from 184 family medicine trainees. These trainees analysed a total of 702 patients with MUS. Manual coding was used for quantitative content analysis.

Results
In the coding process, 49 codes were developed that included broader research fields about using the “Careful Assessment” tool for managing patients with MUS. The codes were grouped into four theoretically grounded, logical categories in accordance with the elaborated theoretical concept: multi-purpose utility; improved patient management; in-depth knowledge and new skills; and patient response.

Conclusion
The study demonstrated that, in the view of Slovenian FMT, the “Careful Assessment” tool has multi-purpose utility. The study showed that FMT felt that this tool helps them in systematic patient management. Their opinion is that it helps them establish a trusting relationship with patients, which is a precondition for providing further treatment.

Abstract

Aim
Vitamin D (VitD) is involved in calcium and phosphate homeostasis, bone health, and normal functioning of the immune system. VitD status is monitored using serum 25-hydroxy-vitamin D (25(OH)D) as a biomarker. Serum 25(OH)D concentrations below 30 nmol/L indicate VitD deficiency and below 50 nmol/L indicate insufficiency. VitD can be synthesised endogenously in human skin when exposed to ultraviolet B (UVB) radiation. In the absence of sufficient UVB-light exposure, VitD intake becomes the main source of VitD, with a recommended daily intake of 20 μg. The aim of this study was to conduct a review and meta-analysis on the abovementioned topics, focusing on scientific studies in various Slovenian populations.

Methods
We conducted a systematic review and meta-analysis of published scientific papers, academic theses, or conference contributions reporting serum 25(OH)D status and VitD intake across various Slovenian populations. A search was carried out using Web of Science, Scopus, Medline, and the Slovenian library database.

Results
We identified 43 pertinent studies that addressed 25(OH)D status and 16 that addressed VitD intake. Serum 25(OH)D status was generally low across all populations, and notable seasonal variability was observed. VitD intakes were below 5 μg in all studies.

Conclusions
A general observation is that various population groups across Slovenia are at high risk of vitamin D insufficiency and deficiency, particularly during wintertime. Regarding vitamin D intake, all included studies reported daily intakes below the recommended level. We also identified key research gaps that need to be addressed to support further public health decision-making.
A Comparative Structural Analysis of Four Radiosonde Models
Authors: Hegyi Norbert , Jósvai János 
Published: December 2021

Abstract
In this study, we first performed a comprehensive structural analysis of four models of radiosondes (devices intended for use as the meteorological probe of a sounding balloon) manufactured by three different companies – Graw, Vaisala and Meteomodem. The radiosondes were disassembled for visual inspection and manual measurement, three-dimensional computed tomography images were taken of their inner structure, and the outer shapes of the radiosondes were scanned with a structured-light three-dimensional scanner. The structural properties of the radiosondes thus identified were then compared to one other, based on which the Meteomodem M10 was ranked as the least harmful in a potential collision. Next, the Meteomodem M10 radiosonde was used in collision tests with a heavy target and with a pumpkin model, in order to evaluate the possible damage caused by and to the radiosonde in different types of collisions.
Proposal for a New Concept of Night Transport in Urban Transport Žilina
Authors: Mihalik Tomáš , Šperka Adrián , Hrudkay Karol 
Published: December 2021

Abstract
Night urban transport in Slovakia is realized by public transport only in selected regional cities. In the long run, due to the increasingly available taxi services and the lack of connection between rail transport and night public transport, it has a declining share in passenger transport. A new operation proposal is necessary for the regional city of Žilina, which considers not only the factor of continuity, but also other factors, such as economical operation and travel expenses. The main task of the article is therefore to propose a more usable concept that will attract as many satisfied passengers as possible to this segment of public transport.
Driving Duration Difference in Road Freight Transport Between Vehicles Up to and Over 3.5 Tonnes
Authors: Beňuš Ján 
Published: December 2021

Abstract
Working conditions for drivers in the European Union and Slovakia are governed by European and National regulations. Regulations lay down rules on driving times, breaks and rest periods for drivers of lorries and buses to improve working conditions and road safety. There is no doubt that with increasing freight performance, the number of carriers and vehicles in the field of road freight transport is also increasing. Therefore, in connection with the current EU legislation, which aims to increase road safety, attention is paid to adopting regulations for all road haulage operators and carriers. The purpose of this paper is to show difference between road freight transport performed by vehicles up to 3,5 tonnes and vehicles transporting goods where the maximum permissible mass of the vehicle, including any trailer, or semi-trailer, exceeds 3,5 tonnes.

Cissampelos owariensis is a medicinal plant with a wide range of therapeutic uses. In this study, the objective was to further assess its antiproliferative potential using cell proliferation and tumor suppressor markers. Solvent extraction of C. owariensis leaves was done using methanol. Twenty (20) male albino Wistar rats were randomly divided into four groups 1–4 (n=5) and respectively administered with methanolic extracts of C. owariensis at 0, 100, 300 and 500 mg/kg for 30 days. After treatment, the hepatic tissues were processed and examined histologically and immunohistochemically for cell proliferation (Ki-67) and tumor suppressor (p53) proteins. Immunoexpression of the proteins was quantified using image-J software, the data analyzed with SPSS version 20 and values compared using t-test and one-way analysis of variance. The histological results showed no significant variation in hepatic histomorphology of treated Groups 2–4 relative to non-treated Group 1. However, the immunohistochemical results showed significant (p< 0.05) down-regulation in Ki-67 protein expression and a concomitant significant (p< 0.05) up-regulation in p53 protein expression in hepatic tissues of treated Groups 2–4 relative to non-treated Group 1.These inverse expression patterns of cell proliferation and tumor suppressor proteins following exposure to methanolic extracts of C. owariensis may suggest the antiproliferative potential of the plant extracts.

Published: December 2021

В рамках настоящего исследования был проведен анализ существующих работ, посвященных интерпретации показаний тактильных сенсорных устройств, по результатам которого была предложена модель машинного обучения, позволяющая осуществлять оценку величины приложенного давления к поверхности тактильного сенсора давления емкостного типа. В качестве опорных моделей обработки и интерпретации сигналов данного устройства в работе рассматривались несколько методов машинного обучения: линейная регрессия, полиномиальная регрессия, регрессия дерева решений, частичная регрессия наименьших квадратов и полносвязная нейронная сеть прямого распространения. Обучение опорных моделей и апробация конечного решения проводилась на авторском наборе данных, включающем в себя более 3000 экземпляров данных. Согласно полученным результатам, наилучшее качество определения величины приложенного давления продемонстрирован решением на основе полносвязной нейронной сети прямого распространения. Коэффициент детерминации и средний модуль отклонения для данного решения на тестовой выборке составили 0,93 и 13,14 кПа соответственно.
Currently, in the field of developing sensing systems for robotic means, one of the urgent tasks is the problem of interpreting the data of tactile pressure and proximity sensors. As a rule, the solution to this problem is complicated both by the dependence of the indicators of tactile sensors on the type of object’s material and by the design features of each individual device. In this study, an analysis of existing works devoted to the interpretation of the readings of tactile sensor devices was carried out. According to the analysis results a machine learning model was proposed that allows estimating the amount of pressure applied to the surface of a tactile pressure sensor of a capacitive type. The architecture of the proposed model includes two key blocks of data analysis, the first one is aimed at recognizing the type of interaction object’s material and the second is devoted to the direct assessment of the magnitude of the pressure applied to the sensor. Several machine learning methods were considered as supporting models for processing and interpreting the signals of this device: linear regression, polynomial regression, decision tree regression, partial least squares regression and a fully connected feedforward neural network.

Оценка положения экваториальных границ аврорального овала при разных магнитосферных условиях, несёт в себе информацию о формирующихся плазменных структурах, глубине их проникновения во внутреннюю магнитосферу, движении внутренней границы плазменного слоя и т.д. Развитие алгоритмов определения положения видимой экваториальной границы аврорального овала является важной частью исследований, связанных с разработкой моделей химического состава ионосферы, моделей авроральных высыпаний частиц и оценки точности этих моделей. Немаловажную роль исследования полярных сияний (прогноз, интенсивность, положение) играют и для развития туристического сегмента в Арктике и информационных ресурсов служб мониторинга и прогноза космической погоды. В рамках исследования оценки точности положения видимых границ овала сияний в моделях авроральных высыпаний частиц была выбрана наземная наблюдательная сеть оптических камер всего неба проекта THEMIS, запущенная в 2008 г., и модифицированная модель OVATION Prime (PC), разработанная в отделе Геофизики ФГБУ «ААНИИ использующая в качестве входного параметра наземный индекс полярной шапки (PC-индекс).
The location of the equatorial boundaries of the auroral oval under different magnetospheric conditions contains information about the forming plasma structures, the depth of their penetration into the inner magnetosphere, the motion of the inner boundary of the plasma layer, etc. The development of methods and algorithms for determining the position of the visible equatorial boundary of the auroral oval is an important part of research related to the development of models of the chemical composition of the ionosphere, models of auroral particle precipitation, and assessment of the accuracy of these models. Research of aurora borealis (forecast, intensity, position) also plays an important role for the development of the tourist segment in the Arctic and information resources of space weather monitoring and forecasting services.

Работа посвящена исследованию гамма-фона в городской среде Петропавловска-Камчатского (Камчатский край), а именно в парках и зонах отдыха. Измерения мощности поглощенной дозы проводились на разработанном коллективном Томского политехнического университета (ТПУ) дозиметре с использованием органического сцинтиллятора ВС-408, который является схожим по техническим характеристикам с БДКГ-01. С целью вычисления поправочного коэффициента для перевода показаний дозиметра из имп/с в нЗв/ч был проведен ряд калибровочных измерений с точечными источниками гамма-излучения – 60Co и 137Cs. Разработанным дозиметром проводились измерения длительностью не менее 5 минут в различных районах города Петропавловска-Камчатского, особое внимание уделялось исследованию объектов техносферы
из материалов, являющимися природными источниками повышенного гамма-излучения. Исследования показали, что памятник В. И. Ленину и стела «Город воинской славы» в центре города Петропавловска-Камчатского содержат граниты у их основания, которые дают завышенный гамма-фон
The work is devoted to the study of the gamma background in the urban environment of Petropavlovsk-Kamchatsky (Kamchatka Territory), namely in parks and recreation areas. Measurements of the absorbed dose rate were carried out on a scintillation organic dosimeter developed by the team of the Tomsk Polytechnic University (TPU), which is a more budgetary analogue of the BDKG-01. In order to calculate the correction factor for converting the dosimeter readings from impulses/s to nSv/h, a number of calibration measurements were carried out with point sources of gamma radiation – 60Co and 137 Cs. The developed dosimeter carried out measurements with a duration of at least 5 minutes in various districts of the city of Petropavlovsk-Kamchatsky, special attention was paid to the study of technosphere objects made of materials that are natural sources of increased gamma radiation. Studies have shown that the monument to V. I. Lenin and the stele « City of Military Glory » in the center of the city of Petropavlovsk-Kamchatsky contain granites at their base, which give an overestimated gamma background.
