Opis:
Groundwater is a vital resource for domestic, agricultural, and industrial activities, as well as for ecosystem services. Despite this, the resource is under significant threat, due to increasing contamination from anthropogenic activities. Therefore, to ensure its reliability for present and future use, effective management of groundwater is important not only in terms of quantity (i.e. abstraction) but also quality. This can be achieved by identifying areas that are more vulnerable to contamination and by implementing protective measures. To identify the risk and delineate areas that are more exposed to pollution, various groundwater vulnerability assessment techniques have been developed across the globe. This paper presents an overview of some of the commonly used groundwater vulnerability assessment models in terms of their unique features and their application. Special emphasis is placed on statistical methods and overlay-index techniques. The assessment of the literature shows that statistical methods are limited in application to the assessment of groundwater vulnerability to pollution because they rely heavily on the availability of sufficient and quality data. However, in areas where extensive monitoring data are available, these methods estimate groundwater vulnerability more realistically in quantitative terms. Many works of research indicate that index-overlay methods are used extensively and frequently in groundwater vulnerability assessments. Due to the qualitative nature of these models, however, they are still subject to modification. This study offers an overview of a selection of relevant groundwater vulnerability assessment techniques under a specific set of hydro-climatic and hydrogeological conditions.

Opis:
This paper draws on ethnographic fieldwork to present an account of the current situation of one of the indigenous villages of Taiwan in the face of a natural disaster related interference of the state and non-government organisations, and the struggle of its inhabitants to maintain cultural integrity and socio-political independence. After Morakot typhoon hit the island of Taiwan in August 2009 causing numerous landslides, several indigenous villages including those situated in the mountains' interior, were permanently relocated to the vicinity of the plains and mainstream Han Chinese society. In the process of relocation the government as well as non-government organizations were involved. To the villagers who took an active part in the negotiations process, the new relocation site became an opportunity to unite most of the previously scattered members of the community However the conflicts instigated during the negotiations led several families to refuse relocation. In order to survive in the abandoned village they have returned to traditional mode of subsistence. In their eyes they have become the protectors of their group's traditional territory and sole guardians of the village. Hence by the means of traditional and state provided socio-political structures the villagers have successfully blocked government as well as non-government projects regarding the village, which led to shift of internal authority Through this experience the villagers came to realize increasing sociocultural differences between the mainstream Han Chinese society and their own heritage as well as growing distance between the inhabitants of the original village and the residents of the relocated settlement. Their experience led them to a firm conviction about traditional knowledge to be the guarantor of prosperity and solution to any problems.

Opis:
Groundwater is a very important natural resource to support the activities of the residents of Pakis District, Malang Regency. On the other hand, increased activity puts pressure on groundwater quality. Agricultural intensification, urbanisation, and industrialisation can be sources of pollutants. Hydrological factors, topography, lithology, and surrounding rainfall are triggers for contamination of groundwater. The main objective of this research is to determine the characteristics, quality of groundwater, and its susceptibility to pollution. To complete this research, geoelectric measurements were carried out at 43 points spread throughout the study area and sampling of 18 shallow wells in agricultural, residential, and industrial areas for chemical analysis. All data obtained were analysed to create a map of the spatial distribution of groundwater vulnerability. The results show that the groundwater in the study location is in the transition zone and flows through the volcanic rock layers. The level of groundwater pollution is in the uncontaminated status to heavily polluted with pollutants in the form of heavy metal manganese and Escherichia coli bacteria. The spatial distribution of groundwater intrinsic vulnerability shows low, moderate, and high levels of vulnerability, respectively 32.99%, 60.87%, and 6.14% of the research area. Groundwater specific vulnerability associated with land use factors shows that 26.25% are negligible, 42.46% are low, and 31.29% are moderate. From this it can be concluded that the study area has been polluted both geogenically and anthropogenically, therefore, special actions must be taken to restore the quality of groundwater.

Opis:
We analyse the factors used for assessing groundwater intrinsic vulnerability to pollution in the mean residence time estimation method, providing a final vulnerability evaluation. The following factors were analysed: depth to shallow groundwater, effective precipitation infiltration coefficient, terrain inclination, volumetric water content of soils and rocks in the unsaturated zone and volumetric water content of the topsoil. GIS surveys were performed for two geomorphologically diverse regions: a highland piedmont and a lowland plain in Poland (Central Europe). In both cases, groundwater had spatially diverse vulnerability to contamination. The research method used relied on determining the percentage participation of the area with particular values of the parameters analysed in areas of different degrees of vulnerability. Knowledge of the extent and distribution of variability of the parameters analysed in areas of particular degrees of vulnerability helps explain the causes of spatial variation in groundwater intrinsic vulnerability to contamination in given areas.

Opis:
One of the many problems facied by users, producers or network owners as well as those who deal with cybersecurity on a daily basis is the issue of vulnerabilities in Internet of Things devices. Although the most popular vulnerabilities are often presented to the general public, the vast majority of them are still known only to cybersecurity specialists, and not to the users who own the vulnerable device. Consequently, it is the users who are most likely to be at risk. It is advisable to increase user awareness of the dangers of owning and using unsecured devices as well as provide access to information about vulnerabilities. Ideally, we would like to have a single source where information about vulnerabilities and exploits related to IoT devices would be collected, aggregated and correlated. Among other things, the article presents various sources of actionable information as well as an open repository that presents information about vulnerabilities and exploits in an accessible way.

Opis:
The 2019 PBC document views relationships between parents and children, masters and servants, “shepherds” and “the flock,” civil authority and citizens as asymmetric. The structure of the document suggests that these relationship systems are based on shared human experience and a common theological foundation: they appear to repeat the pattern of the parent-child relationship and originate in the obligation to obey God. Using the document as a starting point, I would like to outline what the concept of asymmetric relationships can mean today. In search of common perspectives, I will compare New Testament texts with the interpretation of asymmetry in today’s social ethics discourse. The inequality and asymmetry of different persons and groups seem to be an undeniable fact, causing tension that can be resolved fruitfully by parties who take responsibility for each other in the presence of a “third.”

Electricity significantly determines the possibility of development of technical civilisation, both on a global and local scale. The availability of energy determines the diversity of civilisational development of communities inhabiting particular areas of the earth. The Internet, in turn, as a tool conducive to the human species, induces many opportunities while simultaneously generating threats. The Supervisory Control and Data Acquisition (SCADA) systems used in the power industry are key elements in the operation of industrial facilities and critical infrastructure, while also being vulnerable to cyberattacks. Successful cyberattacks can cripple internal processes, cause financial losses and potentially lead to unwanted block-outs.

GNSS vulnerability
Opis:
Jamming of GNSS signals can be both a consequence of accidental activities and an intentional act. This issue is lately discussed as an essential threat for the use of satellite navigation systems. This is especially dangerous in the face of common usage of GPS — like systems in everyday life and the great belief of everyday users in the truth of devices indications. In spite of the legal prohibition of using them, jammers are commonly accessible, especially in the Internet. Until recently even specialists have shared the conviction that the broadband GPS signal is not a subject of disturbances in contrast to older wire-less communication techniques because its power level is below natural level of noises and in addition it is randomly coded. But nowadays jammers are very often successfully applied, which is confirmed in many reports. The average user has not the suitable knowledge about the specificity of the jamming and has no technical possibilities of the detection of jammer signals. Receivers, which can indicate the presence of perturbative signals, became accessible a few months ago only. Presently accessible jamming monitors can also determine the direction of interferer signal transmission. There are also specially designed receivers with anti-jamming mechanism, which are, however, not commonly accessible. The possible way of countermeasure the jamming in the GNSS receiver are discussed in this paper.
Zagłuszanie sygnałów GNSS, które może być skutkiem zarówno przypadkowych, jak i celowych działań, jest ostatnio oceniane jako jedno z największych zagrożeń dla użytkowania satelitarnych systemów nawigacyjnych. Jest to szczególnie istotne w obliczu stosowania systemów opartych na idei GPS w życiu codziennym i przy powszechnym zaufaniu przeciętnych użytkowników we wskazania tych systemów. Pomimo oficjalnego zakazu posługiwania się zagłuszaczami, są one powszechnie dostępne, zwłaszcza za pośrednictwem Internetu. Jeszcze do niedawna specjaliści podzielali pogląd, że bardzo szerokie pasmo sygnału GPS nie jest podatne na zagłuszanie, w przeciwieństwie do klasycznych technik radiowych, ponieważ i tak w warunkach naturalnych poziom sygnału w tym systemie jest niższy od poziomu szumów, a ponadto jest kodowany losowo. Jednakże obecnie z pożądanym skutkiem stosowane są tzw. jammery, co potwierdza wiele doniesień. Przeciętny użytkownik nie ma dostatecznej wiedzy na temat specyfiki zagłuszania, jak również nie dysponuje odpowiednim oprzyrządowaniem, aby wykryć sygnały zagłuszające. Zaledwie w ostatnich miesiącach pojawiły się pierwsze odbiorniki, które są zdolne uprzedzać obecność sygnałów zakłócających. Dostępne są również monitory zagłuszania zdolne wskazać nawet kierunek, z którego sygnał zakłócający dochodzi. Istnieją też odbiorniki mające specjalne rozwiązania umożliwiające pracę w warunkach zakłóceń, jednak nie są powszechnie dostępne. W artykule przedstawiono zasadnicze możliwości przeciwdziałania zagłuszaniu w systemach klasy GNSS.

Opis:
Timbulsloko is a village on the coast of Sayung District, Demak Regency that is severely affected by coastal erosion. The coastal erosion in the Timbulsloko Village is mainly caused by the removal of mangrove areas, which has eliminated the function of the natural breakwater for the coast of the Timbulsloko Village. This study aimed to mitigate the coastal erosion in the form of structural and non-structural protection. Structurally (physically), mitigation is conducted by protecting the coastal area with the application of environmentally friendly coastal protection technology in the form of a Permeable breakwater with a Hybrid Engineering structure. Furthermore, the effectiveness of two different structure segments in damping waves from September 2020 – March 2021 will be measured. In contrast, non-structurally, mitigation is conducted in a non-physical way by analyzing the Coastal Vulnerability Index of Timbulsloko Village based on the parameters of Coastal Typology, Average Tidal Range, Significant Wave Height, Coastal Slope, Coastal Geomorphology, Sea Level Rises, and Shoreline Displacement using the CVI method. The effectiveness of the permeable structure’s wave damping is determined by the initial wave height and transmission wave height measured by the ultrasonic sensor. On the basis of segment differences, the Permeable Breakwater Segment 2 with a distance between bamboo of 0.25 m has better effectiveness than a Permeable Breakwater Segment 1 with a distance between bamboo of 0.5 m. The results of the Coastal Vulnerability Analysis show that the Timbulsloko Village is vulnerable to coastal disasters, especially coastal erosion.

Opis:
This study makes use of Remote Sensing and Geographic Information System techniques to assess the vulnerability of structures along river channels in Oyo metropolis. The vulnerable rates were classified into High, Medium and Low using 30m, 45m and 60m buffer distances from the middle of the river channels while network analysis was also carried out to attend to any emergency operation. To achieve this feat, a geospatial database was designed and created with various analyses carried out on the entities extracted from the satellite image of the study area. Such analyses include, buffering to categorize the vulnerable zones into the various classes, network analyst menu of ArcGIS 10.2.2 was employed to find the best route from the Fire Service Station to the point of accident and also an alternative route in case of a barrier or barriers on the best route. This showed that a total of 881 buildings will be affected in any instance of flooding that is within 60m from the middle of the river channels in the study area. 399 buildings fall in high vulnerable zone accounting for 45.29% of the buildings examined for vulnerability in the study area, 245 buildings fall within the moderately vulnerable zone accounting for 27.81% and 237 buildings fall within low vulnerable zone at 26.90%. The best route from the Fire Service Station to the point of accident is gotten to be 2.3 Km while the alternative route is 2.7 Km when a barrier is placed on the best route during rescue mission indicating 0.4 Km difference between the two routes. Maps, tables and a chart were produced for various results.

The risk management concept is based on assessment of several risk components: susceptibility in the form of calculation of a priori probability of forest destroying by fire, vulnerability based on calculation of posteriori probability of forest destroying by fire and based on modelling the fire behaviour in FARSITE environment. We also briefly introduce an approach to set the measures to prevent the forest fire occurrence and to manage it to minimize its impacts on human, environment and property (resilience).
