Experimental Validation of Maximum Constant Boost Control and Switching Frequency Optimal for three-phase Quasi-Z-Source Converters
2020
This paper presents a modified modulation scheme for quasi-Z-Source converters, based on the Maximum Constant Boost Control (MCBC) concept and Switching Frequency Optimal (SFO) as reference signal. The effectiveness of the proposed technique is validated by comparing the obtained results (in terms of AC harmonic content and voltage stress) with those carried out from traditional modulation schemes. For this reason, a test bench has been assembled and the benefits of the SFO MCBC modulation scheme have been valuated.
Relations between Kindergarten Teachers’ Occupational Well-being and the Quality of Teacher-child Interactions
2020
Research Findings The aim of this study was to examine associations between two aspects of teachers’ occupational well-being, i.e., teaching-related stress and work engagement, and the quality of teacher–child interactions in Finnish kindergarten classrooms. Participants were 47 kindergarten teachers with their classrooms of 6-year-old children. Teacher–child interactions (i.e., emotional support, classroom organization, and instructional support) were observed twice during the kindergarten year (fall and spring), using the Classroom Assessment Scoring System (CLASS). In addition, teachers completed questionnaires on stress and work engagement. The results indicated that teaching-related st…
Teknostressi häiritsee keskittymistä, unta ja ihmissuhteita, mutta sen torjumiseen on keinonsa
2022
Teknologian liiallisen käytön aiheuttama stressi eli teknostressi kuormittaa monia työssä ja vapaa-ajalla. Vaikka esimerkiksi sosiaalisen median käyttäminen tuntuu ihmisistä usein mukavalta, pitkän päälle se myös tuottaa stressiä, heikentää keskittymiskykyä ja vie energiaa muulta elämältä. Teknostressiä voi kuitenkin lievittää muutamalla yksinkertaisella keinolla. nonPeerReviewed
Opettajien työhyvinvointi ja sen yhteys pedagogisen työn laatuun
2020
The aim of the study was to examine the factors related to teachers’ stress and well-being at work, and how teachers’ occupational well-being is associated with the pedagogical quality of their work in the classroom. Moreover, we investigated the factors related to teachers’ work engagement and recovery from work. Questionnaire data was collected from 54 first grade teachers from Central Finland in fall 2017 and spring 2018. The questionnaire included background information about the teacher and the class, the teachers’ experiences of their occupational well-being, work-related stress, and burnout, as well as their recovery from work, work engagement, and interactional style in the classroo…
The Quality of Teacher-child Interactions and Teachers’ Occupational well-being in Finnish Kindergartens: A Person-centered Approach
2022
Research Findings: The aim of the present study was to identify profiles of kindergarten teachers based on the observed quality of interactions with the children in their classrooms and to explore possible differences between the profiles in terms of teachers’ occupational well-being and teacher and classroom characteristics. Participants were 54 Finnish kindergarten teachers whose interactions with children were observed with the Classroom Assessment Scoring System (CLASS Pre-K). The teachers also completed a questionnaire about their occupational well-being. Four interaction profiles were identified: Highest Quality, Moderate Quality, Lower Quality with Limited Negativity, and Lower Quali…
Stressi ja terveys väestöllisissä ryhmissä : tutkimus ihmisten stressi- ja sairastuvuusalttiudesta
2003
Tämän tutkielman aiheena on stressin ja terveyserojen mittaaminen väestöllisissä ryhmissä. Tutkimuksen lähtöasetelma on varsin psykologinen. Aluksi pyritään erittelemään ihmistyyppejä persoonallisuuden piirteiden perusteella Antonovskia (1987) ja Kobasaa (1979) mukaillen. Tämän jälkeen tutkitaan löydettyjen ryhmien asenteita ja tuntemuksia sellaisten mentaliteetin ominaisuuksien kanssa, joilla on todettu olevan yhtäläisyyksiä stressiin ja sairastuvuuteen. Mentaliteetin osa - alueet kuvastavat Williamsin ja Huberin (1986) luokittelemia sisäisiä stressinaiheuttajia. Lopuksi testataan, onko stressinsietokyvyllä ja koetulla stressillä eroja demografisten ryhmien kesken. Nämä ryhmät ovat tavanom…

EFFECTS OF THE ENRICHED-ORGANIC DIETS COMPOSITION ON EUROPEAN SEA BASS (Dicentrarchus labrax) NEW TOOLS FOR FISH WELFARE EVALUATION IN AQUACULTURE
2021
In recent years, concern for the welfare of animals, including fish, has a strong impact on public opinion, putting pressure not only on producers and the scientific community, but also on institution to guarantee adequate "standards” for animal welfare. The market today challenges the production capacity of aquaculture by asking for products with consistently high quality. Unlike other farming methods, there is a lack of scientific information on the welfare of fish reared under intensive aquaculture conditions. Among the various aspects that characterize aquaculture, the increase in fish welfare has an impact on public opinion also for economic reasons whereby is very important to keep an…

Emergence of technostress among employees working with physical robots
2023
Despite the growing body of literature on technostress, there is limited knowledge about the emergence of technostress among people working with physical robots. In this paper, we aim to address this research gap by exploring how technostress emerges among employees working with physical robots. The study was based on qualitative online questionnaire responses from 197 present or previous users of robots at work. Based on our data, we identified several robot-related environmental conditions that contributed to perceived work-related stress. Our findings reveal that the emergence of technostress among employees working with physical robots has distinct characteristics and that the technostr…
