An Initial Security Analysis of the Personal Transaction Protocol
2003
Our society is becoming increasingly dependent on the rapid access and processing of information. The number of handheld mobile devices with access to the Internet and network-based software and services is exploding. Research indicates [1] that by the end of 2002 there will be over 1 billion mobile phone owners globally with Internet access, and that this number is going to grow exponentially in the nearest future. By 2006 the number of interconnected mobile device users is expected exceed the worldwide Internet subscriber population. It is estimated that in a few years there will be three times as many of these devices worldwide as personal computers.
MOOCEP: Un método para construir cursos masivos para Adultos Mayores: Usando una creación MOOCEP
2018
Hoy en día, la población de adultos mayores se ha incrementado significativamente en relación al total de la población mundial, así también este segmento en los últimos años ha mostrado una mayor adherencia e interés a los avances tecnológicos, entre ellos el Internet y sus servicios con la finalidad de desarrollar diferentes actividades tales como entretenimiento, información de actualidad, aprendizaje de diferentes tópicos, entre otros. Sin embargo, las aplicaciones y sitios web no tienen en cuenta los requisitos específicos de las personas de la tercera edad. De ahí, es necesario contar con metodologías, procesos y herramientas, las mismas que tengan en cuenta formas apropiadas de intera…
Achievement perceived, parenting, internet use and adolescent behavior
2019
espanolResumen El uso intensivo de internet puede contribuir a desarrollar disfunciones psicosociales graves en la adolescencia. El objetivo de esta investigacion es analizar las relaciones de la percepcion de eficacia academica con el uso de internet para ocio, los estilos de crianza y los problemas exteriorizados e interiorizados en la adolescencia (agresividad proactiva, reactiva, fisica y verbal, afiliacion a pares rebeldes e inestabilidad emocional). Han participado 762 adolescentes de 12 a 17 anos (M = 13.69; DT = 1.40; varones 52.8%). Utilizan internet en tiempo de ocio entre cero y 98 horas semanales, de ahi que la poblacion se haya distribuido en cuartiles. Las variables se han obt…
Low-invasive multisensor real-time acquisition system for the assessment of cardiorespiratory and skin conductance parameters
2022
In recent years, the attention to the health and comfort of the individual, together with the electronic miniaturization progress, have led to an increased interest in the development of biomedical devices that are able to acquire a multitude of biomedical signals. Such devices should be wearable and comfortable during daily use, to be thus suitable for continuously monitoring psychophysical health states. In this context, we have designed and realized a portable biomedical device capable of real-time acquisition of electrocardiographic (ECG), photoplethysmographic (PPG), breathing and galvanic skin response (GSR) signals, for a noninvasive monitoring of multiple physiological parameters. T…
Elektroniskie informācijas resursi studiju darbā
2017
Bakalaura darbā “Elektroniskie informācijas resursi studiju darbā” tika veikts pētījums par Latvijas Universitātes dažādu fakultāšu studentu elektronisko resursu izmantošanu studiju nepieciešamībai. Pētījuma mērķis bija noskaidrot, cik lielu lomu elektroniskie informācijas resursi ieņem studiju darbā, un kuri no tiem ir visizplatītākie un iecienītākie dažādu Latvijas Universitātes fakultāšu studentiem, kā arī uzzināt, kuri no elektroniskajiem informācijas resursiem ir visiecienītākie studentu vidū. Pētījuma laikā tika secināts, ka visizplatītākais un biežāk lietotais elektroniskais informācijas resurss ir internetā pieejamās meklēšanas programmas visu fakultāšu studentiem, kas piedalījās pē…
Internet of Things and biometric data versus employee privacy in the Polish case
2020
The Internet of Things is a modern technology that affects every area of human life, includ- ing employment relationships. IoT enables the processing of specific personal data categories, including biometric data, and entails the risk of employers interfering with employee privacy. Due to the use of intelligent solutions, the issue of employee privacy, which is, in princi- ple, a personal right subject to protection, becomes significant. The relationship between an employee and an employer includes two subjects of legal protection, the meeting of which may lead to internal contradiction. There is the employee’s dignity and privacy, on the one hand, and protection of reasonable interests of …
Farmaceitiskā konsultācija interneta aptiekā
2015
Interneta aptiekas parādījās pasaulē salīdzinoši nesen, taču šis jaunais pakalpojuma veids mūsdienās ir izplatīts un turpina attīstīties gandrīz visās civilizētās valstīs, arī Latvijā. Lai nodrošinātu klientu apmierinātību un pienācīgu aprūpi, farmaceitam jābūt spējīgam veidot pozitīvu komunikāciju, izzināt un saprast klienta vajadzības, sāpes un problēmas. Farmaceits spēj to izdarīt, apgūstot empātiju kā vienu no savām profesionālajām iemaņām, un tad pielietot to, konsultējot klientus pa telefonu vai elektroniski. Praktiskā darba rezultātā tika atklātas statistiski ticamas atšķirības starp vecumu grupām un respondentu nepieciešamība saņemt empātiju farmaceita konsultācijas laikā interneta …
The use of mobile technology for online shopping and entertainment among older adults in Finland
2017
Older adults use mobile devices for online shopping as often as younger adults.Mobile-based entertainment use is most typical for younger male adults.Older female adults use mobile-based entertainment least frequently.Age, household structure and high education predict mobile-based online shopping.Mobile-based entertainment use is best predicted by age and gender. Older adults are becoming an important market segment for all internet-based services, but few studies to date have considered older adults as online shoppers and users of entertainment media. Utilising the concept of life course, this article investigates the use of mobile technologies for online shopping and entertainment among …
An Energy-Autonomous Wireless Sensor with Simultaneous Energy Harvesting and Ambient Light Sensing
2021
Wireless sensor nodes (WSNs) are generally powered by batteries, which results in a substantial limitation to the places where the nodes can be installed, to the maximum number of deployable devices, and to the node lifetime. To meet the demand for Internet-of-Things (IoT) applications that require a large number of maintenance-free, low cost, wireless sensor nodes, this paper proposes a wireless sensor platform with a single photovoltaic transducer that performs the dual role of harvesting energy and sensing ambient light. This dual use allows even smaller and cheaper nodes that do not require any form of supporting external power, with a reduced component count. The device implements off-…
A Battery-Free Wireless Smart Sensor platform with Bluetooth Low Energy Connectivity for Smart Agriculture
2022
Smart agriculture systems, which integrate sensors and data analysis into agricultural production processes, are increasingly proving an effective solution for reducing food production waste, yield production increase, and product quality improvement. In this context, this paper deals with a wireless sensors platform for humidity, temperature, and light detection that has the peculiarity to be self-powered and battery-free. The main advantage of the proposed solution is the elimination of maintenance interventions due to battery replacement. Therefore, the availability of install-and-forget sensors allows an easy diffusion for a capillary detection of plant health and growth parameters thro…
