The Given

Analysis and risk assessment are procedures which help to improve knowledge and are very important in practice. Risk assessment is possible to conduct only on the basis of exact accurate and tested information about the given system, which truly defines the given system within the spatial–temporal context. High standards of maintenance and treatment are closely linked with the requirements for quality and reliability forestry machinery and technological equipment. These standards are closely related to the maintenance of the equipment. This manuscript is focused on the reliability of standard forest machines used in the Slovak forestry. They are relatively modern and useful in the process of transporting and handling trees. This research showed the possibility of decreasing the production costs related to the maintenance of the devices and how to increase the final profit. The results of the research showed that the analysis of reliability is significant regarding to the quality of performed maintenance and the costs paid for it.

Depth Interview

This paper aims to measure the quality of the services delivered by a court by assessing the satisfaction of court users and service providers, i.e., magistrates and court officials. For that purpose, a case study was carried out and data were collected by means of a questionnaire based on the SERVPERF instrument, in which perceived service quality is measured, considering court users, magistrates, and court officials’ perceptions of post-service performance. One hundred and fifty-eight questionnaires were successfully returned. An in-depth interview was later conducted to the court administrator to gain a richer understanding of the results achieved and ask follow-up questions. Overall, findings revealed that court users, magistrates, and court officials clearly have a positive view of the services provided, although improvement is needed, particularly in the court’s facilities and technological equipment. The current research sheds some light on the potentialities and difficulties of assessing service quality in the judiciary and contributes to the validation of the SERVPERF instrument in this context.

Analysis Process

Requirements elicited from requirements elicitation session with stakeholders are usually comes in bulk and it is impossible to execute them simultaneously. In addition, the requirements elicited are unfiltered and usually low quality including ambiguous, incomplete and unclear. The low quality of requirements are then refined in the next activity which is requirements analysis in requirements engineering. This paper aims to integrate requirements prioritization techniques focused on the factor of risk in requirements analysis since the early stage of requirements engineering. It is seems to have a little evidence on that requirements prioritization focus on the factor of risk in requirements based on our conducted literature review. This paper begins with elaboration on requirements prioritization, further to the aspects of requirements prioritization, criteria for best suited technique, a literature review on requirements prioritization techniques. We then proposed a framework for requirements analysis with the integration of requirements prioritization. A case study is elaborated for a better vision on the process of the proposed approach. Finally, this study is believed to produce a better quality of requirements from the requirements analysis process.

Abstract NASA’s shift towards streamlined business practices depends on innovative management processes and tools. One such innovation, Risk Management (RM), has been levied as an Agency-wide requirement with corresponding policies which define the RM process. However, these policies are top level and do not necessarily ensure the institutionalization and transfer of the process’s best practices. Thus to implement the Agency’s philosophy while ensuring consistency and quality of risk assessments, the NASA Ames System Safety and Mission Assurance Office developed the Integrated Risk Assessment (IRA) process. IRA is the systematic use of both inductive and deductive assessment methods applied such that a risk is assessed for its potential harm to any resource and is tailored to the activity’s overall technical and programmatic constraints. Independently these methods are not unique; but their ensemble, which IRA represents, provides a powerful yet practical RM tool. This paper presents an overview and case study of the IRA process.

Alzheimer is one of the most frequent types of dementia. With the increasing extension of life expectancy, and an increasing incidence above sixty-five years. Near to thirteen million cases are foreseen in 2050 with an estimate cost above two hundred billion dollars in associated care expenses. It becomes important to take measures to ensure quality of life to patients, carers and promote the sustainability of public and personal finances. The major concerns with those patients are memory faults with the tendency for wandering and get lost. The present work proposes a solution for permanent monitoring, risk assessment and reaction, when needed, while extending battery autonomy for the worn device. Data is periodically uploaded to be processed and analysed in a remote infrastructure such as FIWARE. The aim is to establish profiles that better adapt to each citizen of the evergrowing community of dementia patients, including those with Alzheimer disease.

Clear Description

Genetically Engineered (GE) plants are the demand of time for increased need of food. The regulation system, followed from the development of a GE plant to its release into the environment is categorized into separate stages for maintaining the proper biosafety including Environmental Risk Assessment (ERA). ERA identifies potential risks and its impacts through science based evaluation process where it follows a case by case study. All the countries dealing with GE plants follow specific guidelines to conduct a successful ERA. In this study, ERA guidelines of 4 developing and 4 developed countries including Bangladesh were compared in terms of required data and information against ten criteria. Surprisingly, an adequate amount of data and information requirements (e.g. if the intended modification has been achieved or not, growth habit of GE plants, potential adverse effects on the human health etc.) matched between all the countries. However, a few differences of data requirement such as agronomic conventions of non-transformed plants, clear description of experimental procedures followed etc. were also observed in the study. Moreover, the result indicates that only a few countries provide instructions on the quality of the data used for ERA. Thus, if the similarities are recognized in a more framed manner then the approval pathway of GE plants can be shared.

Habitat fragmentation alters fire regimes by changing the spatial and temporal context in which fire operates, potentially altering ecosystem state and threatening taxa. In the fragmented wheatbelt of Western Australia, spatial patterns of contemporary fire and their effects on biodiversity conservation are poorly understood. We addressed this by: (1) determining if fire regimes differed between vegetation remnants of differing sizes and uncleared vegetation, using analysis of satellite imagery; (2) determining vegetation structural responses to time since fire in three habitats: mallee-shrub, Acacia shrublands and mallee-heath; and (3) exploring the consequences of these differences, using the fire-sensitive malleefowl (Leipoa ocellata) as a case study. Fire was infrequent in small remnants, more frequent in large remnants, and most frequent in uncleared areas. Key vegetation structural attributes for malleefowl, such as canopy and litter cover, increased beyond 45 years post-fire in mallee-shrub, reached a plateau in mallee-heath after 30–40 years, and declined in Acacia shrublands after 25–40 years. Senescence in long-unburnt vegetation, combined with rare contemporary fires, suggest progressive decline in habitat quality of Acacia shrublands for malleefowl in the wheatbelt. In the adjacent, continuously vegetated landscapes, more frequent (and extensive) fires in structurally developing mallee-shrub communities are of concern for malleefowl conservation.
