Nowadays, it is important to promote environmental management in organisations so that natural resources are subject to a conservation process that allows them to be maintained over time. In addition, this is a good way to increase the environmental awareness of the different actors in society. Therefore, the objective of this study is to evaluate the perceptions of workers concerning the relationship between environmental management and the conservation of natural resources in tourism companies in Ayacucho, located in the Andean region of Peru. The research is of a basic type, with a quantitative approach and a non-experimental, correlational-exploratory design. The survey technique was used and the data-collection instrument was a questionnaire addressed to 600 workers on environmental management, with the dimensions of planning, implementation and operation and verification; and on conservation of natural resources, with the dimensions of biodiversity monitoring and consolidation of the protected area. The results show that 39% of workers disagree with the planning of their company, 47% neither agree nor disagree with the operations of their company and the implementation of its projects and 47% disagree with their company’s methods of assessing the success of its operations. These results show that an environmental management model should be proposed to improve the conservation of natural resources and to contribute to the revaluation of resources and the promotion of biodiversity protection in order to create environmental awareness in society.
Introduction and Importance: Virtual education has impacted the vision of people during the coronavirus pandemic, as by spending more time on the computer, it compromises the eye health of the person causing long-term visual problems. So the objective of this investigation is to assess computer-related ophthalmic syndrome in teachers of a University of the Province of Cañete. Methods: This is a quantitative, nonexperimental, descriptive, cross-sectional study on a total population of 63 teachers, who answered a digital survey using the sociodemographic data and the Computer Vision Syndrome Questionnaire. Clinical Discussion: From the results it can be observed that the results of computer ophthalmic syndrome in the university teachers of the province of Cañete, where 51 (81%) of the teachers do not present the computer vision syndrome and 12 (19%) presented with the computer vision syndrome. Conclusion: The population conducting virtual education as well as the students should be educated on the measures to be taken to prevent computer ophthalmic syndrome and its consequences.
The remanent domain structures of composite element magnetic barcodes have been imaged using photo-emission electron microscopy with contrast from x-ray magnetic circular dichroism (XMCD-PEEM) and analysed with reference to the results of micromagnetic simulations. The magnetisation configuration at the end of wide strips is found to be perpendicular to the majority magnetisation direction. This transitions to an incomplete rotation for nominal strip widths below 300 nm and is found to affect the mechanics of magnetisation reversal for nominal strip widths below 200 nm, owing to a difference in magnetisation orientation when an external magnetic field is applied that is just smaller than the magnetic coercivity of the structures and a corresponding change in reversal dynamics. This change in domain structure as strip width decreases is consistent with both the influence of shape anisotropy and with measurements of magnetic hysteresis. The magnetisation reversal characteristics of composite element structures are found to be dependent on the relative magnetisation configurations of neighbouring strips, which in turn are found to vary stochastically upon the application and removal of a magnetic field along the easy axis of the structure. It is found that the application of a canted field is necessary to ensure sharp, consistent magnetisation reversal of bits when writing a binary code. These results confirm that either improved lithography of narrower strips or non-rectangular elements would be necessary to further increase the number of individually programmable bits in a barcode.
Currently, working conditions have been evolving continuously, which makes it necessary to incorporate teleworking as a means of support to fulfill the tasks entrusted. However, this type of employment brings with it vulnerabilities within companies that are not prepared for such a situation. For this reason, a teleworking model is proposed to improve the management of information security in organizations in the commercial sector. This research is of a basic type with a non-experimental design and correlational level, with a quantitative approach, the survey technique, and a questionnaire was used as an instrument that was applied to 70 workers in the commerce sector. The results show that 54.29% consider the organizational change in companies as deficient, 62.86% indicate the use of technologies as deficient, and 84.29% consider that the level of confidentiality of the information is regular. These results reflect that information security management must be implemented to provide greater reliability, integrity, productivity, control, and protection to teleworking processes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
