Opis:
Several studies on the assessment of soil organic carbon (SOC) stocks have been carried out at the global level. However, reliable information on SOC stocks is not readily available at the regional level. In addition, very few studies have assessed the factors responsible for the variation of SOC stocks, in particular the effect of plant communities. For this purpose, the main objective was to analyze the effects of three plant communities and ecological parameters on the SOC stock in the Mamora forest. Specifically, the authors looked to examine the relationships between SOC stock and plant communities and to define the main parameters that directly influence SOC stock. Ten soil profiles with three replications were sampled at each plant community, from which SOC stock was determined. To assess the effect of plant communities on SOC stocks, phytosociological surveys were carried out according to the phytosociological stigma method developed by Braun-Blanquet. The results show that the SOC stocks in cork oak soils are characterized by high variability, with values ranging from 55 t•ha-1 to 95 t•ha-1. Indeed, the findings of this study showed that the SOC stocks fluctuated significantly with plant communities. In addition, SOC stocks were also affected by the interactions between plant communities, the amount of litter and the density of the cork oak stand. These outcomes of this study highlight the critical need to incorporate community-specific carbon values into future carbon sequestration modeling.

Tematem artykułu jest studium użycia układu FPGA do emulacji działania mikroprocesora w zastosowaniach dydaktycznych. Zaprezentowano proces powstawania rozwiązania od etapu analizy wymagań, przez architekturę do opisu implementacji, ze wskazaniem istotnych uwarunkowań użytkowych i technologicznych oraz kluczowych decyzji. Wynikiem przedstawionych prac jest moduł użyty po raz pierwszy w zajęciach laboratoryjnych w bieżącym semestrze.
The paper presents a case study of using the FPGA chip for emulating a microprocessor system for didactic purposes. Inside the FPGA chip there are implemented an open source Z80 processor core together with code and data memory blocks connected to the proces-sor bus as well as UART peripheral. The emulated processor bus behaviour is compliant with the original Z80 bus. Therefore, a student is able to connect external devices to the bus (by means of the appropriate connectors, three-state buffers and address decoding circuits). The UART peripheral, which is connected to the external USB/UART converter, is used by the NoICE commercial monitoring application. By means of this application, a student is able, among others, to load own program to the Z80 system, execute the code stepwise or in the free run mode, observe and modify content of the memory connected to the Z80 processor bus. Z80 processor core is shared between the NoICE monitor program and the user's code. The presented hardware platform allows for implementation of other 8-bit microprocessors as well. This way students may learn the modern System On Chip concept (SOC). Moreover, the module can be also used to teach the issues of logic circuit implementation inside the FPGA. The result of presented work is a versatile laboratory module, used since 2010 in the microprocessor systems laboratory at the Warsaw University of Technology.

W artykule przedstawiono projekt i wyniki badań eksperymentalnych mikrosystemu w układzie SoC Zynq (Xilinx) przeznaczonego do dystrybucji strumienia danych z chaotycznych generatorów pseudolosowych (PRBG) w sieci LAN. Opisano implementację kilku wariantów architektur chaotycznych generatorów binarnych sekwencji pseudolosowych. Kompletny system zajmuje 2% przerzutników i 7% bloków LUT dostępnych w układzie XC7Z020. Szybkość transmisji danych w sieci LAN, w zależności od konfiguracji systemu, wynosi od 8,8 Mb/s do 53,4 Mb/s. Opracowano aplikację do badań i wspomagania prac projektowych z wykorzystaniem proponowanego mikrosystemu.
This paper presents a concept, design and experimental results of a SoC-based microsystem with Zynq device from Xilinx, for distribution of chaotic pseudo-random bit-stream from PRBG via LAN. Several variants of PRBGs architectures have been described and tested. The complete system requires about 2% of flip-flops and 7% of LUTs available in the XC7Z020 device. The maximum speed of data transmission on LAN, depends on the system configuration, and varies from 8.8 Mbps to 53.4 Mbps. A dedicated computer application has been developed to support the research and design with use of the proposed microsystem. Pseudo-random bit-stream generators are used e.g. in cryptography and for testing digital systems. Often there is a need for high-speed transmission of data streams to multiple recipients at the same time. The described system supports the distribution of data obtained from embedded PRBGs over the LAN. In order to manage the distribution process, a dedicated client-server has been proposed. The hardware platform and objectives of the system for generation and distribution of pseudo-random sequences are discussed. There are presented the main features of the tools used for development of the project, the software and the library of utility modules that can be used in dedicated user applications.

The project was focused on optimization of the PRNG architecture to achieve the highest possible output throughput of the generated pseudo-random sequences. As a result we got a model of the pipelined PRNG that was implemented in Cyclone V SoC from Altera and verified experimentally. All versions of the PRNG were tested by standard statistical tests NIST SP800-22. In addition, we also provide a brief comparison with the PRNG implementation in SoC from Xilinx.

Zmienną osobowościową obniżającą nasilenie przesądności w ciąży zgodnie z założeniami okazało się wysokie poczucie koherencji.
The article presents the problem of superstitious behaviors undertaken by women in the situation of waiting for the birth of a child. The results of own research conducted on a group of 166future mothers are presented. A slight intensification of the phenomenon was shown, with a tendency to strengthen it in those women whose level of superstition was declared to be generallyhigh. A personality variable that decreases the intensity of superstition in pregnancy is, accordingto assumptions, a high SOC.

Opis:
Background: Police officers meet many stressors as part of their occupation. The psychological resource "sense of coherence" (SOC) protects against ill-health, but its impact on coping resources for stress situations has not been studied in the population of police officers. Different approaches to investigate the significance of SOC for different outcomes have been identified in literature, leading to some difficulties in the interpretation and generalization of results. The aim was therefore to explore SOC and the coping resources, and to examine the significance of SOC for various coping resources for stress using different models in a sample of Swedish police officers providing on-the-beat service. Materials and Methods: One hundred and one police officers (age: mean = 33 years, SD = 8; 29 females) were included, and the Orientation to Life Questionnaire (SOC-29) and the Coping Resources Inventory (CRI) were used. The dependent variable in each regression analysis was one of the coping resources: cognitive, social, emotional, spiritual/philosophical, physical, and a global resource. Global SOC-29 and/or its components (comprehensibility, manageability, and meaningfulness) were investigated as independent variables. Results: All CRI and SOC-29 scores except for that of spiritual/philosophical resources were higher than those of reference groups. Manageability was the most important component of SOC for various coping resources in stress situations used by police officers. Conclusion: A deeper study of manageability will give useful information, because this component of SOC is particularly significant in the variation in resources used by police officers to cope with stress. Salutogenesis, the origin of well-being, should be more in focus of future research on workplaces with a high level of occupational stress.

In this paper an algorithm for co-synthesis of distributed embedded systems is presented. The algorithm is based on iterative improvement heuristics, taking into consideration sophisticated modifications and possibilities of further improvements. Starting from the solution with the highest performance, architecture of the system is modified until it achieves the lowest cost. It has been observed that the algorithm presented has the capacity of getting out of the local minima. Experimental results showed high efficiency of the algorithm. Almost all results obtained with the help of the algorithm were significantly better than the results obtained with the help of Yen-Wolf algorithm presented in the literature.

Objective: There are two theories (by Horowitz and by Foa) which attempt at explaining the process of posttraumatic stress disorder (PTSD) development by information dissonance. The purpose of the present study was to verify these theories via cross-sectional and longitudinal studies. Materials and Methods: The study based on a cross-sectional design was performed on a representative group of Polish firefighters. The study using a longitudinal protocol was conducted among police officers. The level of PTSD was assessed using the Questionnaire for PTSD Measurement (K-PTSD). The sense of coherence (SOC) was measured with the Polish adaptation of the Orientation to Life Questionnaire by A. Antonovsky. Results: In the cross-sectional study, the correlation coefficients between K-PTSD and SOC were –0.35 (p < 0.001) in the group of firefighters and –0.47 (p < 0.001) in that of police officers. In the longitudinal study, the relationship between SOC and PTSD symptoms appeared to be curvilinear and had the U-letter shape. Therefore, we used ANOVA for statistical analysis. Unfortunately, the F(2.31) = 1.900 and p > 0.05 indicated that the tendency we observed was not statistically significant. Conclusions: We would like to propose two possible explanations for the difference in the relationships between SOC and PTSD symptoms obtained in the studies employing the cross-sectional and the longitudinal protocols.

The study was conducted to determine the factors affecting the intention of people to segregate garbage in Vinh Chau town, Soc Trang province, Vietnam by surveying 198 households. Cronbach’s alpha analysis method, EFA analysis, and linear regression analysis were used in the study. The analysis results of Cronbach’s Alpha index, KMO and Bartlett's test showed that the questionnaire data used in the study was highly reliable and were suitable for EFA analysis. The results of linear regression analysis identified three factors including "subjective norm", "control of cognitive behavior" and "perceived level of garbage classification information" that had positive impact on intention of domestic solid waste classification of local people in Vinh Chau town, Soc Trang province, in which "subjective norm" was considered to be the most influential factor on the intention to classify domestic solid waste in the study area. Besides, the intention of the people to segregate the domestic solid waste was highly appreciated, but it has not been widely implemented in the locality. Therefore, the study proposed some governance implications based on the factors affecting the intention of people to classify household solid wastes. In particular, local authorities should pay special attention to propagating and disseminating policies and guidelines on the information of domestic solid waste and implementing a model of waste segregation at source.

Opis:
The use of lithium-ion battery energy storage (BES) has grown rapidly during the past year for both mobile and stationary applications. For mobile applications, BES units are used in the range of 10–120 kWh. Power grid applications of BES are characterized by much higher capacities (range of MWh) and this area particularly has great potential regarding the expected energy system transition in the next years. The optimal operation of BES by an energy storage management system is usually predictive and based strongly on the knowledge about the state of charge (SOC) of the battery. The SOC depends on many factors (e.g. material, electrical and thermal state of the battery), so that an accurate assessment of the battery SOC is complex. The SOC intermediate prediction methods are based on the battery models. The modeling of BES is divided into three types: fundamental (based on material issues), electrical equivalent circuit (based on electrical modeling) and balancing (based on a reservoir model). Each of these models requires parameterization based on measurements of input/output parameters. These models are used for SOC modelbased calculation and in battery system simulation for optimal battery sizing and planning. Empirical SOC assessment methods currently remain the most popular because they allow practical application, but the accuracy of the assessment, which is the key factor for optimal operation, must also be strongly considered. This scientific contribution is divided into two papers. Paper part I will present a holistic overview of the main methods of SOC assessment. Physical measurement methods, battery modeling and the methodology of using the model as a digital twin of a battery are addressed and discussed. Furthermore, adaptive methods and methods of artificial intelligence, which are important for the SOC calculation, are presented. In paper part II, examples of the application areas are presented and their accuracy is discussed

Opis:
Climate change is driving the transformation of energy systems from fossil to renewable energies. In industry, power supply systems and electro-mobility, the need for electrical energy storage is rising sharply. Lithium-based batteries are one of the most widely used technologies. Operating parameters must be determined to control the storage system within the approved operating limits. Operating outside the limits, i.e., exceeding or falling below the permitted cell voltage, can lead to faster aging or destruction of the cell. Accurate cell information is required for optimal and efficient system operation. The key is high-precision measurements, sufficiently accurate battery cell and system models, and efficient control algorithms. Increasing demands on the efficiency and dynamics of better systems require a high degree of accuracy in determining the state of health and state of charge (SOC). These scientific contributions to the above topics are divided into two parts. In the first part of the paper, a holistic overview of the main SOC assessment methods is given. Physical measurement methods, battery modeling, and the methodology of using the model as a digital twin of a battery are addressed and discussed. In addition, adaptive methods and artificial intelligence methods that are important for SOC calculation are presented. Part two of the paper presents examples of the application areas and discusses their accuracy.

Na przykładzie rzeczywistego obszaru sterowania, obejmującego kilka skrzyżowań, zaprezentowano proces specyfikacji, syntezy i implementacji takich sterowników w technice SoC.Dla konkretnego układu FPGA przytoczono raporty z wykorzystania zasobów i uzyskanych parametrów czasowych sterownika obszarowego.
In contrast to industrial process control systems, the achievements of contemporary electronics of the last several years, such as work-ing out hardware description language HDL, and accessibility of programmable logic devices FPGA have not been used in designing control devices of local level of ITS [4] up to the present moment. The paper presents an original methodology for design of new class local controllers of road traffic in railway traffic control implemented in programmable logic devices. The research results obtained at the Faculty of Transport (Warsaw University of Technology) of specialized prototypes of single-system reconfiguration controllers SoC show that the operating speed of such controllers exceeds the speed of currently used microprocessor controllers by hundreds of thousands times, with the improvement of reliability parameters by hundreds of times. It has been shown that the proposed class of specialized controllers can be used not only on the local level, but they can also be used for area controlling, encompassing several crossroads. The process of specification, synthesis and implementation of such a controller in SoC technology has been presented for a sample area of three neighboring crossroads (Figs.1 and 2). The example presented shows that specialized reconfigured road traffic controllers implemented in FPGA (Fig. 3)devices can be used not only on the local level, but also on area controlling level, and so in ITS.

The article presents an experimental system enabling the monitoring of the state of charge (SOC) of a conventional lead-acid battery. Described include selected methods to estimate the state of charge. Next, algorithms developed as part of the work were presented, which were then implemented in the processor system. A constructed simulation model was also presented, which allows additional verification of the correctness of functioning of the solution presented in this article. To this end, based on the review of the SOC methods used, algorithms have been developed in a simplified and modified version based on the so-called Coulomb Counting. In order to verify the correct operation of the constructed experimental system, the obtained test results were compared not only with the battery manufacturer's data, but also with the results obtained by computer simulation.

Opis:
Introduction: Anxiety and depressive disorders belong to the most prevalent mental diseases. Concomitance of anxiety and depression is very strongly correlated with increased sense of guilt, low self-esteem and hopelessness, which significantly contributes to worse social functioning. The sense of coherence (SOC) is a factor which influences the ability to cope with stress and is inseparably related with health. A high level of SOC makes people more self-confident and gives them strength to fight with the disease. Aim: Defining the correlation between the level of the sense of coherence and the level of depression in people treated for anxiety disorders, as a determinant having an influence on maintaining the optimal health. Material and methods: The research was carried out among 96 patients treated in the Anxiety and Affective Disorders Ward in Bydgoszcz. The sense of coherence was assessed using Antonovsky’s Orientation to Life Questionnaire (SOC-29) and the level of depression was assessed using the Beck Depression Inventory. Results: People suffering from anxiety disorders have a low level of the sense of coherence and a high level of depression. A strong negative correlation was found between the level of the sense of coherence and the level of depression: with a lower level of the sense of coherence the level of depression grows and vice versa. Conclusions: The obtained results may significantly affect the level of understanding and accepting the people with anxiety disorders. Determining the level of the sense of coherence and the level of depression may have a signif
Wstęp: Zaburzenia lękowe oraz depresyjne należą do najczęściej występujących zaburzeń psychicznych. Współwystępowanie lęku i depresji ma silny związek z nasileniem poczucia winy, niskiego poczucia własnej wartości i beznadziejności, a to znacząco wpływa na gorsze funkcjonowanie społeczne. Poczucie koherencji (SOC) jest czynnikiem wpływającym na umiejętność radzenia sobie ze stresem i jest nierozerwalnie związane ze zdrowiem. Wysoki poziom SOC sprawia, że ludzie czują się bardziej pewni siebie i mają siłę do walki z chorobą. Cel: Określenie związku pomiędzy poziomem poczucia koherencji a stopniem depresji u osób leczonych z powodu zaburzeń lękowych, jako czynnika wpływającego na utrzymanie optymalnego stanu zdrowia. Materiał i metody: Badaniem objęto 96 pacjentów Oddziału Zaburzeń Lękowych i Afektywnych Collegium Medicum w Bydgoszczy. Poczucie koherencji określono za pomocą Kwestionariusza Orientacji Życiowej (SOC-29) autorstwa Aarona Antonovsky’ego, a stopień depresji oceniono skalą Aarona Becka. Wyniki: Chorzy na zaburzenia lękowe mają niski poziom poczucia koherencji i wysoki stopień depresji. Stwierdzono silny ujemny związek pomiędzy poziomem poczucia koherencji a stopniem depresji – wraz ze spadkiem poziomu poczucia koherencji wzrasta poziom depresji, i odwrotnie. Wnioski: Otrzymane wyniki mogą mieć znaczący wpływ na poziom zrozumienia i akceptacji choroby u osób z zaburzeniami lękowymi. Określenie poziomu poczucia koherencji i stopnia występowania depresji może znacząco wpływać na terapię i posłużyć jako wykładnik w przewidywaniu i planowaniu opieki nad pacjentem.
