Effects of COVID-19 lockdown on musculoskeletal pain, physical activity and work environment in Estonian office workers transitioning to working from home.
No full textBackground
Due to the COVID-19 pandemic, emergency situation for social distancing was implemented in many countries, including Estonia. For most office workers, the lockdown caused a sudden shift from working at the office to working from home. The lockdown offered an opportunity to investigate how working from home affects musculoskeletal pain (MSP), physical activity (PA), work environment factors and their inbetween relationships among office workers.
Objective
The aim of this study was to evaluate the COVID-19 lockdown caused changes in MSP, PA, workplace properties and their inbetween relationships among office workers.
Methods
The study was conducted as an online form, which consisted of Baecke Physical Activity Questionnaire, modified NORDIC Musculoskeletal Questionnaire and questions about work environment. The questionnaires were doubled: one for describing the situation during the lockdown, second for describing retrospectively about 3 months before the lockdown. Total of 161 office workers (64,6% female) participated with the mean age of 38,17±9,52 years.
Results
We did not find any significant differences in the prevalence of MSP or between the mean number of body regions suffering from MSP before and during the lockdown. There was a significant (p<0,001, Cohen’s d=0,26) reduction in total PA, a significant (p<0,001, Cohen’s d=0,5) increase in work-related PA and a significant (p<0,001, Cohen’s d=0,42) decrease in sport-related PA during the lockdown. We found a significant drop in both workplace comfort rating (p<0,05, Cohen’s d=0,27) and workplace ergonomics rating (p<0,001, Cohen’s d=1). We recorded a significant negative correlation (r=-0,2059, p<0,01) between the change in self-reported sport-related PA and the change in number of body regions with MSP. We recorded a significant negative correlation between the number of body regions with an onset of MSP during the lockdown with both workplace comfort score (r=-0.262, p<0,001) and workplace ergonomics score (r=-0,2305, p<0,01).
Conclusion
Maintaining habitual physical activity levels and preparing a more comfortable and ergonomic workspace can play an important role in healthier transition to working from home

Deliverable 2.6.1. Mapping the functioning of fish spawning areas with remote sensing
No full textMadala rannikuvee ja sisevee põhjasubstraadi ja -elustiku kaardistustööde läbiviimine kasutades ainult
tavapäraseid kohtvaatluseid on kulukas ja aeganõudev, sest mootorpaatidega proovipunktide
külastamine võib olla ohtlik või võimatu liiga madala vee, kivide ja rohke põhja- ja kaldaveetaimestiku
tõttu. Sageli on sellistes piirkondades võimalik kohtvaatlusi teostada ainult jalgsi vees liikudes. Kui
tugineda ainult kohtvaatlustele, mille arv raskeid liikumisolusid arvestades on madal, jääb
proovivõtuvõrgustik liiga hõredaks, et sellest saadud andmete abil oleks võimalik luua interpoleerimise
või matemaatilise modelleerimise abil rahuldava kvaliteediga kaardikihte. Sellises olukorras on
praeguste tehniliste võimaluste juures ainuke mõistlik lahendus kasutada optilist kaugseiret koos
kohtvaatlustega. See kombinatsioon võimaldab optiliste andmetega katta kogu uuringuala ning leida
matemaatiliste mudelite abil seoseid optiliste (valgusspektrid) ja kohtvaatlustega saadud muutujate
(substraat, elustik) vahel. Seejärel saab leitud mudelite abil ennustada substraadi ja elustiku muutujate
väärtused kogu uuringu ala
PROCESSING OF LANGUAGE SPECIFIC STIMULI AMONG ESTONIAN AND RUSSIAN NATIVE SPEAKERS: AN EEG STUDY
No full textWe studied how linguistic and non-linguistic auditory input is recognized and distinguished by the brain among native and language naïve speakers, and how that might influence the ability to process changes in duration and pitch. 12 Estonian and 12 Russian (with little experience in Estonian) native speakers took part in an MMN experiment using quantity contrast stimuli with changes in pitch and duration. Estonian is a quantity language with a complex and typologically rare three-way contrast while Russian does not exhibit the linguistic quantity category. Two different linguistic stimulus sets (‘SATA’, ‘SAKI’) and one pure tone stimulus set were used. Stimuli differed from each other by the duration of the first vowel [ɑ] (110, 170, 290 ms) and pitch change (level vs falling tone). The sine wave stimulus elicited a more persistent MMN wave with larger amplitude in both language groups, while linguistic stimuli elicited a more pronounced MMN response among the Estonian native speakers. Among the Russian native speakers, the only considerable MMN response for linguistic stimuli was elicited by a clear durational change; while the Estonian native speakers had an MMN response to pitch changes as well. This study is the first ERP study to support previous behavioral findings showing that native Estonian speakers used both durational and pitch cues to discriminate quantities while Russian native speakers used mainly durational cue, while also pointing out some possible limitations and directions for future research
