Opis:
The aim of this study was to show the proportion of workplace accidents related to materials transfer and to decide whether they were more serious than other kinds of workplace accidents. The research material for this study were statistics and data, available in Finland, regarding workplace accidents and fatal accidents. Twenty-five percent of studied fatal accidents were related to materials transfer; 26.9–27.7% of all workplace accidents in Finland in 2003–2007 were workplace accidents related to materials transfer. Over half (54.7%) of workplace accidents related to materials transfer caused disabilities lasting over 3 days. Most accidents related to materials transfer occurred to men aged 20–49 years. The most common types of injuries were dislocations sprains and strains.

Opis:
Workplace safety performance is computed using frequency rate (FR) and severity rate (SR). Only work time lost due to occupational incidents that need to be reported is counted. FR and SR are the 2 most important safety performance indicators that are applied universally; however, calculations differ from country to country. All injuries and time lost should be considered while calculating safety performance. The extent of severity does not matter as every incident is counted. So, a new factor has to be defined; it should be based on the hours or days lost due to each occupational incident, irrespective of its severity. The new safety performance factor is defined as the average human-hour unit lost due to occupational accidents/incidents, including fatalities, first-aid incidents, bruises and cuts. The formula is simple and easy to apply.

The objective of the work was to describe the thermal and snow conditions in the winter period in the Siedlce area. The average daily air temperatures were used in addition to numbers of days with a snow cover of at least 1 cm for the years 2000–2016 obtained from the Meteorological Station in Siedlce. Dates of the beginning and end of the winter season were determined. The average temperature of the winter season was determined in addition to the degree of winter severity, according to Oskin. The average, minimum and maximum values of parameters were calculated. The probability of an occurrence of individual types of winter severity was determined. Next, principal component analysis and cluster analysis were applied, the latter to the group years in terms of the days with a given type of weather in winter. It was found that – on average – the thermal winter began on 5 December and ended on 6th March. The winter was found to have lasted for 66 days. From year to year, there was observed an increase in the average number of days with mild weather. The greatest decline was found for the days with the weather typical of slightly severe and moderately severe winter. The last study years had the highest average number of days with weather typical of mild, slightly severe and moderately severe winter, and the lowest number of the days with weather typical of severe, very severe, unusually severe and extremely severe winter.

Opis:
The heterogeneous population of patients affected by trauma is extremely difficult to systematize. This is due to the diversity of mechanisms of injury, the nature and severity of the injury and the population, which relate to injuries, diverse in terms of gender, age, presence of comorbidities that make up the final severity of the injury and a certain degree of danger to life. The aim of the study was to develop a universal method to assess the severity of injury and loss of life resulting from their consequences, using the parameters available in the Polish administrative databases, a similar diagnostic efficacy as other used scales to assess the severity of damage. Material and methods. The study analyzed a group of 92 463 patients hospitalized due to injuries sustained as a result of injuries in all hospitals of the Lublin region in 2003-2005. Developed catalogs risk factors, reference to the population of the Lublin province. Results. Developed five models predictive of injury severity scale counterparts, which include different combinations of risk factors associated with the type of injury, age of the patient and the mechanism of injury that have been evaluated for their diagnostic efficacy in differentiating the expected outcomes. Prediction model have the best diagnostic efficacy AUROC 0.9615, SE 0.0025 and 95% CI 0,9565-0,9665, hereinafter referred to as Life Hazard Ratio (LHR), which has a similarly high diagnostic efficacy as the other, examined in the work of the rock assess the severity of damage AUROC 0.9585, SE 0.0368, 95% CI0 0.8849-1. Conclusions. 1. The proposed method of use of the International Classification ICD-10 allows the use of regional administrative databases to conduct detailed analyzes of population and monitor trends in the epidemiology of injuries. 2. Developed Life Hazard Ratio (LHR)is a universal method for the objective evaluation of the severity of injuries and the associated risk of life-threatening, can also conduct population studies. 3. LHR has a comparable rate of diagnostic efficacy as other commonly used scales assessing the severity of the injury.

Introduction: Trauma is the leading cause of mortality in people below the age of 45 years. Abdominal trauma constitutes one-fourth of the trauma burden. Scoring systems in trauma are necessary for grading the severity of the injury and prior mobilization of resources in anticipation. Aim: The aim of this study was to evaluate RTS, ISS, CASS and TRISS scoring systems in blunt trauma abdomen. Materials and methods: A prospective single-center study was conducted on 43 patients of blunt trauma abdomen. Revised trauma score (RTS), Injury Severity Score (ISS), Clinical Abdominal Scoring System (CASS) and Trauma and Injury Severity Score (TRISS) were calculated and compared with the outcomes such as need for surgical intervention, post-operative complications and mortality. Results: The majority of the study subjects were males (83.7%). The most common etiology for blunt trauma abdomen as per this study was road traffic accident (72.1%). Spleen was the most commonly injured organ as per the study. CASS and TRISS were significant in predicting the need for operative intervention. Only ISS significantly predicted post-operative complications. All scores except CASS significantly predicted mortality. Conclusions: Among the scoring systems studied CASS and TRISS predicted the need for operative intervention with good accuracy. For the prediction of post-operative complications, only the ISS score showed statistical significance. ISS, RTS and TRISS predicted mortality with good accuracy but the superiority of one score over the other could not be proved.

Opis:
Wstęp: Urazy pozostają główną przyczyną zgonów u osób poniżej 45. r.ż. Jedną czwartą wszystkich urazów stanowią urazy jamy brzusznej. Skale kliniczne stosowane w urazach są niezbędne dla oceny ich ciężkości i wcześniejszego zorganizowania środków w oczekiwaniu na przyjazd chorego. Cel: Celem badania była ocena zastosowania skal RTS, ISS, CASS i TRISS w urazach tępych jamy brzusznej.Materiały i metody: Przeprowadzono prospektywne jednoośrodkowe badanie kliniczne na 43 pacjentach z urazem tępym jamy brzusznej. Obliczono wyniki w: skali oceny ciężkości urazów (RTS), skali oceny ciężkości mnogich obrażeń ciała (ISS), klinicznej skali oceny jamy brzusznej (CASS) oraz w skali ciężkości urazu i obrażeń (TRISS), a także porównano je z punktami końcowymi, takimi jak: potrzeba leczenia zabiegowego, powikłania pooperacyjne i zgon.Wyniki: W niniejszym badaniu większość stanowili mężczyźni (83,7%). Uraz jamy brzusznej był głównie wynikiem wypadku komunikacyjnego (72,1%). Najczęściej dochodziło do urazu śledziony. Wyniki CASS i TRISS były istotne w przewidywaniu potrzeby interwencji zabiegowej. Jedynie dla ISS wykazano istotność w przewidywaniu powikłań pooperacyjnych. Wszystkie skale, z wyjątkiem CASS, istotnie przewidywały ryzyko zgonu. Wnioski: Spośród przeanalizowanych skal, CASS i TRISS przewidywały konieczność interwencji zabiegowej z dobrą dokładnością. W przypadku ryzyka powikłań pooperacyjnych jedynie wynik w skali ISS wykazywał istotność statystyczną. Skale ISS, RTS i TRISS przewidywały zgon z dużą dokładnością, bez przewagi jednej ze skal nad pozostałymi.

Opis:
Anthracnose of holm oak (Quercus ilex L.) was studied in several sites located in Belezma National Park (Eastern Algeria). Disease severity varied according to the site, but symptoms were particularly frequent on leaves supported by south-facing twigs. Leaves inserted on the distal part of twigs were more affected by anthracnose regardless of twigs’ position on trees. The fungal isolates obtained from damaged tissues were sorted to five morphotypes and identified as Apiognomonia errabunda based on morphological characteristics and ITS sequencing. This is the first record of the occurrence of the fungus Apiognomonia errabunda on Quercus ilex in Algeria. Particular climatic conditions marked by late spring rains followed by high temperatures may play a key role in the increased leaf vulnerability of Q. ilex to infection.

Introduction. Depressive disorders are one of the most common psychiatric disorders. Recognition of signs of mental health disorders is not always easy, hence the availability of simple and accurate tools for assessing them is very important in the practice of primary care. Objective. The aim of the study is to assess the theoretical accuracy and reliability of the Patient Health Questionnaire-9 (PHQ-9) in Polish conditions, when applied to general population studies for adults aged between 35–64. Materials and method. The study comprised a population of 4,040 people. Women constituted 59% of the research population and people living in the countryside 65%. The average age of participants was 53.45 ± 7.05 years. According to PHQ-9, 727 people (18.0%) had moderate, moderate to severe or severe depression. PHQ-9 showed a significant positive internal cohesion (Cronbach’s alpha = 0.77), and factor charges oscillated between 0.43–0.63, and the R2 coefficients of determination were in the range of 0.21–0.40. Conclusions. The Polish version of PHQ-9 is a valid tool for diagnosing depression in the general population aged 35–64. Good psychometric properties and compactness make the PHQ-9 a useful clinical and research tool.

The major objective of this study is to identify the flood severity level of the study area using GIS applications. By employing this map, safer habitation zones were established. Direct personal observation and face-to-face interview was done to gather the primary data and Disaster Management center reports, Census reports of Sri Lanka, images and published research reports were used as secondary data. The severity level of flooding in this area was analyzed using SRTM imagery in ArcGIS and overlaid on a Google Earth pro map. The findings of the study established that the highly affected area consisted of around 8.953003 sq·km, the moderately affected area was around 9.190781 sq·km and the lowly affected area was approximately 9.31039 sq·km within the study area. The major causes for flood disaster in this area are the lack of drainage systems in some potential flood regions, the low landscape, poorly maintained drainage systems and the geographical arrangement of the road network. By creating this map, the inhabitants will be aware of danger areas and can relocate accordingly [3, 5-9].

Opis:
The investigation of extreme meteorological drought events is crucial for disaster preparedness and regional water management. In this study, trends in extreme drought events, namely annual maximum drought severity (AMDS) and annual maximum drought duration (AMDD), were examined for the Ceyhan Basin. The analyses of extreme events were conducted using the standard precipitation index (SPI) index for multiple-time scales of 1, 3, 6, 9, and 12 months for 23 meteorological stations located in the Ceyhan Basin, Turkey. The Wallis-Moore and Wald-Wolfowitz methods were employed to determine the homogeneity of the data sets, whereas trend analyses were conducted using Mann-Kendall and Spearman Rho tests. The magnitude of trends was defined by Sen’s slope and linear regression, and change points were detected using the standard normal homogeneity test, Buishand’s range test, and Pettitt’s test. Although increasing trends were detected in most of the stations, only in nine of them, statistically significant results were noted at a significance level of 95%. The results of this paper provide valuable information to water resource management decision-makers in the Ceyhan River Basin for evaluating the effect of droughts and preparing for drought mitigation measures to avoid future drought risks.

Opis:
Smoke can reduce the airport’s visibility and is related to the aviation safety and efficiency. Low visibility has potential safety hazard, such GA-152 crashed in 1997, and thus there is a need to find out the visibility characteristics in airports over Sumatra and Borneo Island caused by 2015 forest fire. This research aims to analyse the spatiotemporal visibility characteristics over airports in Sumatera and Borneo Island using flight rule visibility below minima criteria and hazard probability. The analysis of smoke was characterized using visibility severity index (VSI) that is a function of visibility severity class and its probability level. Spatiotemporal analysis of severity index combined with hotspot and wind numerical weather model indicates that the worst impact visibility occurred in September and October 2015. The lowest visibility was occured over night until afternoon time period. The spread of VSI impact has a tendency to northward and northwestward. The very high VSI levels occurred at airports such: WIJJ (Jambi), WIBB (Pekanbaru), WAGG (Palangkaraya) which were impacted up to 70% of flight operations time with IFR visibility below minima; while the WIOS (Susilo-Sintang), which operates only on VFR, experienced about 92% of VFR visibility below minima at smoke climax period.

Opis:
Pine sawflies (Hymenoptera, Symphyta, Diprionidae) are the most spread foliage browsing insects of pine forests in Europe, especially monovoltinous European pine sawfly Neodiprion sertifer (Geoffroy, 1785) and common pine sawfly Diprion pini (Linnaeus, 1758), which develops in one or two generations per year depending on weather. The outbreaks of both pine sawflies are the most frequent and intensive in the Steppe zone of Ukraine, especially in the Low Dnieper region, where pine forest (Pinus sylvestris Linnaeus and Pinus pallasiana D. Don) was planted on moving sands in the sixties of the 20th century. This research is aimed at the evaluation of the parameters for D. pini outbreak dynamics in the Low Dnieper region. Outbreak severity, specific foci area and mean score of stand threat by D. pini were evaluated from the regional statistical reports. In the regional scale for 1979–2017, notable outbreaks of D. pini were registered in 1982, 1993, 2002, 2006 and 2017. An interval between maximums was from 4 to 11 years, in average 9 years. The growth of foci area in 1979–1998 as compared to 1999–2017 as well as correlation between pine stand area and annual area of this pest’s foci in different forests was not statistically significant. Graphical analysis of dynamics of D. pini focal area for 2010–2017 was done based on individual threat levels. Our study confirms the fact of three outbreaks for this period in three forest and hunting enterprises (FHE), two outbreaks in one FHE and one outbreak in one FHE. An interval between the outbreaks makes three or six years. The causes of such shortening of interval are discussed.

The primary purpose of this study is evaluation of the effects of biochemical parameters, Balthazar score and CTSI on mortality in acute pancreatitis. At the same time, correlations with biochemical parameters, CTSI and Balthazar score were evaluated in patients with AP. Material and methods. In this study, the amylase, lipase, CRP, and procalcitonin values of patients diagnosed with acute pancreatitis were retrospectively recorded. Contrast-enhanced computed tomography (CECT) images obtained at the time of presentation to the emergency department or within seven days of admission were re-evaluated by two radiologists. The CTSI scores and Balthazar scores of the patients were calculated. Results. The study included 240 patients. The amylase level of the patients was positively correlated with the Balthazar score at a statistically significant level (R=0.189, p=0.003). In addition, the relationship between pancreatic scoring systems and mortality, the AUC value for CTSI was 0.9 (95% CI: 0.826-0.973) and was higher than other scoring systems. Conclusion. CTSI had better performance in the prediction of mortality in patients with acute pancreatitis.

Opis:
In a deregulated electricity market, it is important to dispatch the generation in an economical manner and to ensure security under different operating conditions. In this study evolutionary computation based solution for optimal power flow is attempted. Social welfare optimization is taken as the objective function, which includes generation cost, transmission cost and consumer benefit function. Transmission cost is calculated using Bialek’s power flow tracing method. Severity index is applied as a constraint to measure the security. The objective function is calculated for pre and post contingency periods. Real power generations, real power loads and transformer tap settings are selected as control variables. Different bilateral and multilateral conditions are considered for analysis. A Human Group Optimization algorithm is used to find the solution of the problem. The IEEE 30 bus system is taken as a test system.

Opis:
This paper focuses on the issue of big data analytics for traffic accident prediction based on SparkMllib cores; however, Spark’s Machine Learning Pipelines provide a helpful and suitable API that helps to create and tune classification and prediction models to decision-making concerning traffic accidents. Data scientists have recently focused on classification and prediction techniques for traffic accidents; data analytics techniques for feature extraction have also continued to evolve. Analysis of a huge volume of received data requires considerable processing time. Practically, the implementation of such processes in real-time systems requires a high computation speed. Processing speed plays an important role in traffic accident recognition in real-time systems. It requires the use of modern technologies and fast algorithms that increase the acceleration in extracting the feature parameters from traffic accidents. Problems with overclocking during the digital processing of traffic accidents have yet to be completely resolved. Our proposed model is based on advanced processing by the Spark MlLib core. We call on the real-time data streaming API on spark to continuously gather real-time data from multiple external data sources in the form of data streams. Secondly, the data streams are treated as unbound tables. After this, we call the random forest algorithm continuously to extract the feature parameters from a traffic accident. The use of this proposed method makes it possible to increase the speed factor on processors. Experiment results showed that the proposed method successfully extracts the accident features and achieves a seamless classification performance compared to other conventional traffic accident recognition algorithms. Finally, we share all detected accidents with details onto online applications with other users.

Opis:
In Indonesia, there are underground mines for mineral metal such copper (Cu) and gold (Au), built by tunneling towards the mineral location. The purpose of this study was to determine the mapping a concentration of diesel particulate matter (DPM) and assess the impact on health by severity measurement of airflow obstruction of the miners experiencing chronic obstructive pulmonary disease (COPD). The data of DPM were measured with NIOSH method no. 5040 and applied a geostatistical method in mapping concentration at the area of underground mining. A spirometric measurement was conducted to diagnose COPD that is done to the 314 miners. The results showed that the concentrations exceeding the permissible exposure limit (PEL) and spirometric measurement were found for 26 miners (8.3%) who experience COPD (post bronchodilator <0.70). The severity measurement of airflow obstruction of the miners experiencing COPD, severity of airflow limitation for moderate (GOLD 2) was obtained for 14 miners (54%); severe (GOLD 3) for 10 miners (38%) and very severe (GOLD 4) for 2 miners (8%). It can be concluded that the amount of DPM exposure against the severity of airflow limitation with COPD by 0.03, in which the other factors also affect the severity.

Opis:
Architektura, wbrew jakże częstemu traktowaniu jej jako homogenicznej dyscypliny, zajmującej się wyłącznie zrealizowanymi budynkami/budowlami, w dodatku wybranymi, bez kontekstu przestrzennego, jest w istocie fenomenem niesłychanie szerokiego kąta postrzegania, w przeciwieństwie do większości innych dyscyplin, artystycznych, technicznych czy humanistycznych. Wbrew pozorom zależność jej od stopnia wolności, w jakim powstaje, od jej nadmiaru do niedoboru czy wręcz braku, świadczy o jej kondycji. Z zależnością architektury od wolności jest podobnie, czyli ambiwalentnie, jak w przypadku prawa, władzy, religii czy stopnia własności: własne – wspólne.
Architecture is usually treated as the homogenous and independent phenomenon strictly tight with the material result of human activity in the space we live. The problem is quite different: architecture depends on rules and laws, also on the kind of property – private or public, and on other, various circumstances. In creating of architecture we can not be quite free.

Opis:
Snow removal and deicing using snowplow trucks assist transportation agencies to enhance roadway safety and mobility. However, due to slower travel speeds during these operations, motorists often end up in crashes for poor visibility and disturbance of the snow. Despite the risk associated with snowplows, no previous study was found that exclusively investigate the factors associated with injury severity in snowplow-involved crashes. Therefore, this paper presents an extensive exploratory analysis and fills this knowledge gap by identifying the significant contributing factors affecting the occupant injury severity from the aspects of crashes with snowplow involvement. The study utilized eleven years (2010-2020) of historical snowplow-related crash data from Wyoming. Both the binary logit model and mixed binary logit model were developed to investigate the impacts of the various occupant, vehicle, crash, roadway, and environmental characteristics on the corresponding occupant injury severity. As one of the important findings from this research concludes that other vehicle drivers are more responsible than snowplow drivers contributing to more severe injuries in crashes involving snowplows. Recommendations suggested based on the modeling results are expected to help transportation agencies and policymakers take necessary actions in reducing snowplow-involved crashes by targeting appropriate strategies and proper resource allocation.

Opis:
The paper focuses on the analysis of claim severity in motor third party liability insurance under the general linear model. The general linear model combines the analyses of variance and regression and makes it possible to measure the influence of categorical factors as well as the numerical explanatory variables on the target variable. In the paper, simple, main and interaction effects of relevant factors have been quantified using estimated regression coefficients and least squares means. Statistical inferences about least-squares means are essential in creating tariff classes and uncovering the impact of categorical factors, so the authors used the LSMEANS, CONTRAST and ESTIMATE statements in the GLM procedure of the Statistical Analysis Software (SAS). The study was based on a set of anonymised data of an insurance company operating in Slovakia; however, because each insurance company has its own portfolio subject to changes over time, the results of this research will not apply to all insurance companies. In this context, the authors feel that what is most valuable in their work, is the demonstration of practical applications that could be used by actuaries to estimate both the claim severity and the claim frequency, and, consequently, to determine net premiums for motor insurance (regardless of whether for motor third party liability insurance or casco insurance.
