SMS disaster alert system programming
2008
Floods are natural phenomena that profoundly affect the development of human society, as they are the most widespread disasters in the world and they cause the greatest property and human loss. The flood warning system presented in this paper provides a reliable and effective solution, which is complementary to existing traditional warning systems; it employs information and communication technology and specialized devices.

Being hospitalized with a newly diagnosed chronic illness - A phenomenological study of children’s lifeworld in the hospital
2012
The impact of a hospital environment on children has rarely been investigated. Recently, however, the perspective of hospitalized children has been taken into account. Being hospitalized and facing an illness represent a dramatic change in a child’s daily life, and the quality of the environment may influence the child’s experiences. The aim of this study was to investigate the experiences of children being hospitalized with newly diagnosed type 1 diabetes and to obtain an increased understanding of the environmental influences on the children’s lifeworld. The study used a hermeneutic phenomenological approach. The design is a combination of observation of the participant, interviews, and p…
Patient Alert to detect ICD lead failure: efficacy, limitations, and implications for future algorithms.
2006
Aims An algorithm that alerts implantable cardioverter-defibrillator (ICD) patients, in case of abnormal lead impedance (Patient Alert™, Medtronic), may help to recognize lead dysfunction. We aimed to determine the utility of Patient Alert for ICD lead-failure detection in a prospective study. Methods and results Three hundred and sixty ICD patients were followed for 22±14 months. Patient Alert was active for pacing impedance 2000–3000 Ω, and high-voltage conductor impedance 200 Ω. Ten alert events and a total of 29 severe system complications occurred. Patient Alert detected three of 10 ICD lead failures, with a positive predictive value (PPV) of 77.8% for any severe system complication. R…
Validity of the Pupillographic Sleepiness Test for the diagnosis of daytime sleepiness in children and adolescents and its relationship to sleepiness…
2021
Objectives: To report validation data for the Pupillographic Sleepiness Test (PST) in children and adolescents, evaluate its applicability for diagnosing excessive daytime sleepiness and its relationship to sleepiness-associated outcomes. Methods: A cross-sectional diagnostic test accuracy study was performed. Patients underwent three PST at 9 a.m. (T1), 11 a.m. (T2) and 1 p.m. (T3) plus the Multiple Sleep Latency Test (MSLT) on a single day. Additionally, two neurocognitive tests were performed and three questionnaires about quality of life, sleep-related self-efficacy and behavioural aspects completed. Gender-stratified z-values of the natural logarithm of the Pupillary Unrest Index (z-ln…
The effect of alertness and attention on the modulation of the beta rhythm to tactile stimulation
2021
Abstract Beta rhythm modulation has been used as a biomarker to reflect the functional state of the sensorimotor cortex in both healthy subjects and patients. Here, the effect of reduced alertness and active attention to the stimulus on beta rhythm modulation was investigated. Beta rhythm modulation to tactile stimulation of the index finger was recorded simultaneously with MEG and EEG in 23 healthy subjects (mean 23, range 19–35 years). The temporal spectral evolution method was used to obtain the peak amplitudes of beta suppression and rebound in three different conditions (neutral, snooze, and attention). Neither snooze nor attention to the stimulus affected significantly the strength of…
Sleep and alertness in shift work disorder: findings of a field study
2018
Purpose Although shift work disorder (SWD) affects a major part of the shift working population, little is known about its manifestation in real life. This observational field study aimed to provide a detailed picture of sleep and alertness among shift workers with a questionnaire-based SWD, by comparing them to shift workers without SWD during work shifts and free time. Methods SWD was determined by a questionnaire. Questionnaires and 3-week field monitoring, including sleep diaries, actigraphy, the Karolinska Sleepiness Scale (KSS), EEG-based sleep recordings, and Psychomotor Vigilance Tasks (PVT), were used to study 22 SWD cases and 9 non-SWD workers. Results The SWD group had a shorter …
Functioning of the Attentional Networks at Rest vs. During Acute Bouts of Aerobic Exercise
2011
The present study explored the effects of three different activity conditions on three attentional functions: alerting, orienting, and executive control. A group of highly experienced cyclists performed the Attention Network Test–Interactions (Callejas, Lupiáñez, & Tudela, 2004) at rest, during moderate aerobic exercise, and during intense aerobic exercise. Results indicated that aerobic exercise accelerated reaction time and reduced the alerting effect compared with the rest condition. However, aerobic exercise did not modulate the functioning of either the orienting or the executive control attentional networks. No differences in reaction time or attentional functioning were observed …
Innovation at the workplace: Do professional competencies matter?
2014
Abstract This paper analyzes individuals' propensity to innovate in professional environments, by focusing on the specific competency profile of individuals who play a role in the incorporation of product, technological, and knowledge innovations at work. The analysis draws on economic and managerial literature on innovation, innovative behavior, and competencies to gain a better understanding of the relationships between the process of competency development and innovative behavior in working environments. Using data from REFLEX, a European survey on the transition from higher education to labor markets, the empirical component of this study estimates discrete response models to explain th…
Antecedents of International Opportunity Recognition in Born Global Firms
2017
ABSTRACTInternational opportunity recognition has become an important field of research in recent years. This study deals with the effects of entrepreneurial alertness, systematic search, prior knowledge, and social networks on first-time international opportunity recognition of entrepreneurs inside born global firms. In order to answer this research question, a quantitative survey within born global firms was conducted. The empirical results demonstrate that entrepreneurs of born global firms tend to recognize the first international opportunity through a combination of entrepreneurial alertness and systematic search. Furthermore, network relationships are essential for entrepreneurs withi…
