Abstract

Dependence Between the Residential Area Type and the Sense of Security. The Case of Poznań. The need for safety is one of the most important needs of every person. The sense of security level depends to a great extent on the place of residence. The study aims at showing the relationship between the residential area type and the sense of security in Poznań. The author uses the results of the survey on the crime risk conducted among Poznań inhabitants and assess the sense of security level of the following types of residential area: tenement houses area, blockhouses area, dettached houses area and the city center. In the opinion of inhabitants, the highest sense of security level was in the dettached house area. The following positions included: the city center and the blockhouses area. The lowest sense of security level was characteristic for the tenement houses area. The time of the day was at great importance in the context of respondents assessments, during the day the sense of security level was higher than at night, regardless to the residential area type.

Abstract

The focus of this paper is to propose a method for prioritizing knowledge and technology

factor in companies’ business strategy. The data has been gathered and analyzed from

Malaysian-owned company of medium size type industry, employing around 250 employees

and listed in the Malaysian Bourse Stock of Exchange, since 2000. Sense and respond model

is used to determine competitive priorities of the firms. Then knowledge and technology

part of sense and respond questionnaire is used to calculate the variability coefficient i.e. the

uncertainty caused by technology and knowledge factor. The results show that the company

is not leading in term of technology (spear head technology share is around 33%). Therefore,

the enhancement of technology and knowledge to SCA values is not significantly seen in

this study. The usage of the core technologies is around 41% and it might seem relatively

enough. In terms of basic technology, while its share is the lowest (around 25%), it has the

highest source of uncertainties among technology types. In this case, the proposed model

helped to have a clear and precise improvement plan towards prioritizing technology and

knowledge focus.

Abstract

A method for frequency-multiplexed multi-sample gas sensing is presented. It enables measuring multiple samples placed simultaneously in the setup, without any optical or mechanical switching. Samples are measured using heterodyne detection and signal from each sensing path is encoded at different carrier frequency. Subsequently, a signal from particular sample is retrieved through heterodyne beatnote demodulation at unique frequency. This technique is particularly suitable for real-time calibration of the sensor through a sequential (or simultaneous) detection of three signals: from unknown sample, reference sample and baseline. Basic setup is demonstrated and proof-of-concept experiments are presented. Very good agreement with spectra measured using standard tunable diode absorption spectroscopy is obtained.

Abstract

Apart from medical care, medical biological equipment or physical environment biggest impact on our health has our behaviours. According to the Functional Health Model (FMZ) H. Wrony-Polańskiej (2003), pro-health behavior is conditioned by the availability of cognitive and behavioral resources, among which the sense of coherence plays an important role. Aim of the study was assessment of dependence between the sense of coherence and health behaviors of studying students. The study involved 245 second and third year students studying in humanities and science. The study was used the M. Ziarko Health Behavior Questionnaire and the A. Antonovsky SOC-29 Life Guidance Questionnaire. Research analysis has confirmed that there is a statistically significant relationship between health behaviors and the sense of coherence and its components: comprehensibility, manageability and meaningfulness. On the basis of the research conducted and based on the Functional Health Model it can be concluded that an important practical direction is to develop from a young age in healthy children and adolescents a special emphasis on the development of this resource.

Abstract

The main focus of this paper is to propose a method for prioritizing knowledge and technology factor of firms towards sustainable competitive advantage. The data has been gathered and analyzed from two high tech start-ups in which technology and knowledge play major role in company’s success. The analytical hierarchy model (AHP) is used to determine competitive priorities of the firms. Then knowledge and technology part of sense and respond questionnaire is used to calculate the variability coefficient i.e. the uncertainty caused by technology and knowledge factor. The proposed model is tested in terms of two start-ups. Based on the initial calculation of uncertainties, some improvement plan is proposed and the method is applied again to see if the uncertainty of knowledge and technology decreases. In both cases, the proposed model helped to have a clear and precise improvement plan and led in reduction of uncertainty.

Abstract

We define the need for sense-making as the desire to find reliable connections between the objects, situations, and relationships that people encounter. We have proposed and tested that there are possible individual differences in the need for sense-making and that these individual differences are insightful in characterizing individuals and their behaviors. A correlational study (N = 229) showed that need for sense-making was positively related to self-esteem, extroversion, conscientiousness, openness, and sense of control. Additionally, a higher need for sense-making was associated with greater perception of it as an important part of people’s identity. Thus, need for sense-making is relevant to understanding individual differences and can furthermore comprise a significant element of people’s identity. These results break new ground in the study of individual differences in the need for sense-making and can be of great importance in work and organizational psychology.

Abstract

Animals kept outside their natural environment often suffer from boredom. They don’t hunt or have a chance to conduct their mating rituals, and their natural tendency for physical activity is limited by space. These deficiencies affect their psychological well-being. But when it comes to dogs, we can help them by exploiting their excellent sense of smell.

Abstract

Satellite remote sensing provides a synoptic view of the land and a spatial context for measuring drought impacts, which have proved to be a valuable source of spatially continuous data with improved information for monitoring vegetation dynamics. Many studies have focused on detecting drought effects over large areas, given the wide availability of low-resolution images. In this study, however, the objective was to focus on a smaller area (1085 km2) using Landsat ETM+ images (multispectral resolution of 30 m and 15 m panchromatic), and to process very accurate Land Use Land Cover (LULC) classification to determine with great precision the effects of drought in specific classes. The study area was the Tortugas-Tepezata sub watershed (Moctezuma River), located in the state of Hidalgo in central Mexico. The LULC classification was processed using a new method based on available ancillary information plus analysis of three single date satellite images. The newly developed LULC methodology developed produced overall accuracies ranging from 87.88% to 92.42%. Spectral indices for vegetation and soil/vegetation moisture were used to detect anomalies in vegetation development caused by drought; furthermore, the area of water bodies was measured and compared to detect changes in water availability for irrigated crops. The proposed methodology has the potential to be used as a tool to identify, in detail, the effects of drought in rainfed agricultural lands in developing regions, and it can also be used as a mechanism to prevent and provide relief in the event of droughts.

Abstract

The author explicates the concepts of nihilism and the meaning of life as they have been presented by Ivan Turgenev in his masterpiece Fathers and Sons. She examines in detail the question whether Bazarov’s attitude, the novel’s main protagonist’s, challenges traditional ways of living and points to a deeper and more objective meaning of life, or whether his challenge is intended as an attempt to eliminate all prospect of objective meaning attributable to life, and leaves only one viable option, namely that life must be interpreted in purely subjective terms. Relying on her own analysis of Bazarov’s existential outlook, the author contrasts his qualms with the outlook of the main protagonist of the short story Rudin, which shows a man of a completely different character from Bazarov’s. These two incompatible conceptions of life adopted by entirely different characters evoke a somber image of Russian nihilism and help to illuminate ethical assumptions and practical implications of that attitude.

Abstract

We describe construction and investigation results of optical trace gas sensor working in the 3.334–3.337 μm spectral range. Laser spectroscopy was performed with a multipass cell. A setup was elaborated for detection of ethane at the 3.3368035 μm absorption line. Analysis of the gas spectra and the experiment have shown that, beside C2H6, the sensor is suitable for simultaneous detection of methane, formaldehyde and water vapor. Due to nonlinearity of the laser power characteristic we decided to detect the fourth harmonic of signal. Additional laser wavelength modulation was applied for optical interference suppression. In result, the precision of ethane detection of approximately 80 ppt has been achieved for the averaging time of 20 seconds. Long-term stability as well as the measurement linearity have also been positively tested. The system is suitable for detecting potential biomarkers directly in human breath.

Abstract

The article presents the method of identifying surface damage by measuring changes in resistance in graphitebased sensing skin. The research focused on analysis of conductivity anomalies caused by surface damage. Sensitivity maps obtained with Finite Element Method (FEM) in conjunction with the analytical damage model were used to build the coating evaluation algorithm. The experiment confirmed the ability of this method to identify a single elliptical-shape damage. Eight electrodes were enough to locate the damage that covered about 0.1‰ of the examined area. The proposed algorithm can prove useful in simple applications for surface condition monitoring. It can be implemented wherever it is possible to apply a thin layer of conductor to a non-conductive surface.

Abstract

The water’s edge is the most iconic and identifiable image related to the city of Durban and in seeking an ‘authenticity’ that typifies the built fabric of the city, the image that this place creates is arguably the answer. Since its formal establishment as a settlement in 1824, this edge has been a primary element in the urban fabric. Development of the space has been fairly incremental over the last two centuries, starting with colonial infl uenced built interventions, but much of what is there currently stems from the 1930’s onwards, leading to a Modernist and later Contemporary sense of place that is moderated by regionalist infl uences, lending itself to creating a somewhat contextually relevant image. This ‘international yet local’ sense of place is however under threat from the increasingly prominent ‘global’ image of a-contextual glass high-rise towers placed along a non-descript public realm typical of global capital interests that is a hallmark of the turnkey project trends by developers from the East currently sweeping the African continent.

Abstract

Traditional methods of mineral exploration are mainly based on very expensive drilling and seismic methods. The proposed approach assumes the preliminary recognition of prospecting areas using satellite remote sensing methods. Maps of mineral groups created using Landsat 8 images can narrow the search area, thereby reducing the costs of geological exploration during mineral prospecting. This study focuses on the identification of mineralized zones located in the southeastern part of Europe (Kosovo, area of Selac) where hydrothermal mineralization and alterations can be found. The article describes all the stages of research, from collecting in-situ rock samples, obtaining spectral characteristics with laboratory measurements, preprocessing and analysis of satellite images, to the validation of results through field reconnaissance in detail. The authors introduce a curve-index fitting technique to determine the degree of similarity of a rock sample to a given pixel of satellite imagery. A comparison of the reflectance of rock samples against surface reflectance obtained from satellite images allows the places where the related type of rock can be found to be determined. Finally, the results were compared with geological and mineral maps to confirm the effectiveness of the method. It was shown that the free multispectral data obtained by the Landsat 8 satellite, even with a resolution of 30 meters, can be considered as a valuable source of information that helps narrow down the exploration areas.

Abstract

The aim of the paper was to analyse relations between power in professional work and in close sexual relationships. Power in professional work was analysed with respect to the managerial position, the number of subordinates and salary. Power in close sexual relationships was determined on the basis of a sense of reinforcement of power as a sexual motivation, a propensity for sexual domination, the sense of power in relations with a partner in a close relationship, sexual assertiveness, realization of one’s own sexual phantasies and inclination to initiate sexual activity. The research was carried out on a group of 205 participants in which 100 of respondents occupied managerial positions at work and 105 were subordinates. The following tools were used: the Sense of Power Scale (Anderson, John, & Keltner, 2012), the Multidimensional Sexuality Questionnaire (Snell, Fisher, & Walters, 1993), the AMORE scale (Hill & Preston, 1996), the Need for Power and Influence Questionnaire (Bennett, 1988) and a data sheet. The results showed that power in the workplace was correlated a more frequent initiation of sexual activity, greater assertiveness in sexual matters, more frequent realisation of one’s own phantasies and an increased propensity for sexual domination.

Abstract

The aim of the work is to develop a method of landscape dynamics under anthropogenic impact. The developed methodology is tested on the territory of Kostanay region, which is one of the main regions of mining industry development, with a focus on iron ore mining and crop production. Space images and field survey results are used as input materials. In general, the work consists of the following six stages: the first stage includes the selection and processing of space images, the second stage includes the calculation of indices based on data from different channels of space images, the third stage includes field work aimed at collecting information for verification of the obtained results on the basis of RS data, the fourth stage includes the calculation of range values, the fifth stage comprises verification of the obtained indices, and the final sixth stage deals with calculation of the integral index of landscape degradation degree and analysis of landscape dynamics under anthropogenic impacts. The calculation of the integral indicator of the degree of degradation of the natural environment of the Kostanay region, based on the degradation of each indicator in the conditions of anthropogenic impact, allowed for identification of landscapes with different degrees of degradation (from weak to very strong). The research confirmed that landscapes with a high degree of degradation under anthropogenic impact are confined to semi-desert landscapes in the south of the study region. The degradation of these landscapes is associated not only with anthropogenic impacts but also with natural and climatic features that influence the development of landscape pollution processes. On the contrary, landscapes with a weak degree of degradation correspond to the forest-steppe and steppe zones, characterized by a high level of economic development and resistance to anthropogenic impacts. The verification of the obtained indicators by the values of the remaining 25% of field points determines the reliability of the obtained results, ranging from 87% to 92%, confirming the correct choice of methods and techniques for obtaining the results, especially the choice of field methods and vegetation and non-vegetation indices for assessing the selected indicators. Subsequently, based on the verified map of degradation of the natural environment, created through space monitoring for a certain period, it is possible to forecast the functioning of the natural environment in the conditions of anthropogenic impact.

Abstract

Water erosion is a critical issue for Morocco, especially in its semi-arid regions, where climatic and edaphic conditions only allow erratic soil formation and vegetation growth. Therefore, water erosion endangers human activity both directly (loss of arable land, landslides, mudflows) and indirectly (siltation of dams, river pollution). This study is part of the Kingdom’s effort to assess the risk of water erosion in its territory. It is dedicated to the Bin El-Ouidane dam water catchment, one of the biggest water storage facilities in the country, located in the High Atlas Mountains. The poorly developed soils are very sensitive to erosion in this mountainous area that combines steep slopes and sparse vegetation cover. The calculation of soil losses is carried out with the RUSLE model and corrected by estimating areas of deposition based on the unit stream power theory. This method produces a mean erosion rate of around 6.3 t·ha -1·y -1, or an overall annual loss of 4.1 mln t, consistently with the siltation rate of the dam. Primary risk areas (erosion rates > 40 t·ha -1·y -1) account for 54% of the total losses, while they cover only 7% of the catchment. This distribution of the soil losses also shows that the erosion risk is mainly correlated to slope, directing the means of control toward mechanical interventions.

Abstract

The scarcity of annual rainfall, which sometimes spreads over successive years, causes persistent droughts. In order to study the drought severity on the Algerian steppe, we analysed precipitation data (1985–2015) from the weather stations of Ain Sefra, El Bayadh, Tiaret and Djelfa, using drought meteorological indices: the mean deviation, the standardised precipitation index, the rainfall index and the frequency analysis of the rainfall series. Thus, we adopted the diachronic study by satellite remote sensing for the years 2002 (the driest year) and 2009 (the wettest year), which allowed us to better understand the evolution of the steppe rangelands surface and to better interpret their spatial-temporal changes. Drought, as determined by the mean deviation index, occurred during two periods (in sequence and corresponds to 55% the sequences of deficit years), one over 12 years (from 1994/1993 to 2006/2005) and the other over 5 years (1985–1990) and with isolated years. The results of the diachronic study of the vegetation change demonstrate the obvious divergence of the vegetation cover between 2002 and 2009. Drought has impacts on vegetation composition, growth, productivity, structure and functioning of ecosystems, which limits regeneration of vegetation cover.

Abstract

In addition to unthinking anthropogenic meddling with the subtle ecological balance, the territories of Al-Aba Oasis are witnessing various Land Use and Land Cover (LULC) changes. Comprehending LULC is a central facet of upholding a sustainable, friendly, and fit environment. This paper presents a spatiotemporal study of land use and land cover trends in the wetlands of Al-Aba Oasis, an ecologically sensitive area in the west of Ras Tanura in the east of the Kingdom of Saudi Arabia. The study area faces several environmental problems, including the rise in groundwater levels, expansion of agricultural land, urban expansion, and anthropogenic interference with the ecological balance. In this paper, a verified representation of the changes in each LULC class has been made using satellite images. Remote sensing imagery is helpful for studying temporal changes in LULC and providing environmental monitoring data. We analysed Landsat-5 and Sentinel-2 imagery for 1985, 2000, and 2021. The overall precision besides the kappa coefficient for precision assessment indicates the relevance of the LULC classification. LULC map products were overlaid and interpreted based on post-classification change detection methods. The LULC aspects were classified into six classes: water body, waterlogged area, sabkha soil, sandy area, cultivated area, and built- up area. The results prove that from 2001 to 2021, the extension of the built-up area (2.6%) and agricultural land (6.85%) is directly proportional to the population growth (36.5% between 1992 and 2004) and the sabkhas are subject to constant metamorphosis under the joint influence of urban and agricultural land expansion. 100 samples were collected for the years 1986, 2001, and 2021 to assess the accuracy. We reviewed the outcomes of this study by evaluating the accuracy (77, 81, and 84% for 1986, 2001, and 2021 respectively) and comparing the field truth using a GPS (Global Positioning System) sensor. The results of this study are useful in the development of environmental policies during the development of sustainable territorial development programmes of the oasis.

Abstract

The cartography and quantification of irrigated fields in the context of decreasing rainfall constitute a key element for water resources management. Therefore, in this context, the use of remote sensing methods applied to Landsat-type images with a high spatial resolution for monitoring the changes in land use in general and irrigated crops, in particular, is highly relevant. This paper aims to present a method for mapping spatial and temporal changes in irrigated parcels in the Guigou Plain, located in the central Middle Atlas, based on Landsat images and fieldwork. For the years 1985, 1998, 2010 and 2018, the use of a supervised classification method based on the principle of machine learning, fed by precise field surveys, has made it possible to highlight a significant extension of irrigated areas to the expense of pastureland and rainfed crops. Over the entire period under consideration, the results obtained with good precision (98.5% overall accuracy) showed that the area under irrigated crops has increased from approximately 699 ha to 3988 ha, i.e. an increase of 570%. The corollary of this increase is strong pressure on the water resource, especially groundwater. This information on the total extension of irrigated plots can be taken as a reference in the perspective of reasoned management of water resources in the sector.

Abstract

With rapid population increases, people are facing the challenge to maintain healthy conditions. One of the challenges is air pollution. Due to industrial development and vehicle usage air pollution is becoming a high threat to human life. This air pollution forms through various toxic contaminants. This toxic contamination levels increase and cause severe damage to the living things in the environment. To identify the toxic level present in the polluted air various methods were proposed by the authors, But failed to detect the tolerance level of toxic gases. This article discusses the methods to detect toxic gasses and classify the tolerance level of gasses present in polluted air. Various sensors and different algorithms are used for classifying the tolerance level. For this purpose “Artificial Sensing Methodology” (ASM), commonly known as e-nose, is a technique for detecting harmful gases. SO2-D4, NO2-D4, MQ-135, MQ136, MQ-7, and other sensors are used in artificial sensing methods (e-nose). “Carbon monoxide, Sulfur dioxide, nitrogen dioxide, and carbon dioxide” are all detected by these sensors. The data collected by sensors is sent to the data register from there it is sent to the Machine learning Training module (ML) and the comparison is done with real-time data and trained data. If the values increase beyond the tolerance level the system will give the alarm and release the oxygen.
