Published: February 2022

Þrátt fyrir fjölda svefnrannsókna á undanförnum árum er enn margt á huldu um útbreiðslu svefnvenja meðal ungmenna. Nægur nætursvefn er mikilvægur fyrir þroska, heilsu og námsgetu ungs fólks. Markmið rannsóknarinnar var að skoða hvort svefnlengd íslenskra skólanema samræmdist svefnráðleggingum, hver meðalsvefnlengd nemendanna væri og hver munur væri á tíðni ráðlagðs svefns og svefnlengd milli einstakra hópa nemenda.Landskönnunin „Heilsa og lífskjör skólanema“ (HBSC) fór fram árið 2018 meðal nemenda í 6., 8. og 10. bekk. Alls svöruðu 7.159 nemendur á landinu öllu stöðluðum spurningalista. Nemendurnir voru meðal annars spurðir um háttatíma sinn og fótaferðartíma. Viðmið um nægilegan svefn voru borin saman við alþjóðlegar ráðleggingar ungmenna í 6. bekk (9–11 klst./nóttu), og fyrir nemendur í 8. og 10. bekk (8–10 klst./ nóttu).Niðurstöður sýndu að um 30% nemenda í 6., 8. og 10. bekk ná ekki viðmiðum um ráðlagða svefnlengd á virkum dögum. Piltar náðu síður ráðlagðri svefnlengd en stúlkur, og 10. bekkingar mun síður en nemendur í yngri bekkjardeildum. Nemendur sem áttu foreldra af erlendum uppruna sváfu skemur og náðu síður ráðlögðum svefni en aðrir nemendur. Nemendur sem bjuggu með báðum lífforeldrum sínum sváfu lengur og fengu oftar ráðlagðan svefn en nemendur í öðrum fjölskyldugerðum. Þá kom í ljós að nemendur á höfuðborgarsvæðinu sváfu lengur og náðu frekar ráðlögðum svefni en nemendur af landsbyggðinni. Ekki var marktækur munur á lengd nætursvefns eftir efnahag fjölskyldunnar.Umtalsverður hluti íslenskra ungmenna nær ekki nægum nætursvefni. Mikilvægt er að gefa nánari gaum að nætursvefni íslenskra ungmenna, einkum meðal þeirra ungmenna sem fá hvað stystan nætursvefn.

Published: February 2022

Á unglingsárum takast einstaklingar á við ýmsar breytingar og áskoranir. Góð andleg líðan er forsenda velferðar fólks og því vekur það áhyggjur að henni fer hrakandi hjá ungmennum á Vesturlöndum. Áhyggjur beinast einnig að vímuefnaneyslu ungmenna en sífellt koma fram nýjar áskoranir í því efni. Markmið rannsóknarinnar var að kortleggja andlega líðan og vímuefnaneyslu ungmenna og skoða samband þessara þátta við gæði tengsla við foreldra og kyn. Einnig átti að kanna hjá ungmennum samband andlegrar líðanar, gæða tengsla við foreldra, kyns og efnahagslegs bakgrunns við áfengis- og kannabisneyslu. Notuð voru gögn úr rannsókninni Heilsa og lífskjör skólabarna þar sem nemendur í 10. bekk svöruðu spurningalistakönnun. Niðurstöður gáfu til kynna að fjórðungur ungmenna upplifði slök tengsl við foreldra og að þau væru líklegri en hin sem upplifa góð eða mjög góð tengsl, til að líða illa og nota vímuefni. Stúlkur notuðu ekki minna áfengi en drengir þó kannabisneysla þeirra væri minni, þær voru líklegri en drengir til að meta tengsl við foreldra slök og ólíklegri til að meta tengslin mjög góð. Tengsl voru einnig milli andlegrar vanlíðanar ungmenna, slakra tengsla við foreldra og verri fjárhagsstöðu fjölskyldu og þess að vera líklegri en þau sem líður betur, hafa betri tengsl og búa við betri fjárhagsstöðu, til að nota bæði áfengi og kannabis. Jafnframt voru tengsl milli vanlíðunar og vímuefnaneyslu óháð tengslum ungmenna við foreldra. Nýta þarf snemmbær inngrip þegar einkenni um andlega vanlíðan gera vart við sig. Hvetja þarf foreldra til að hlúa að góðum tengslum við börn sín og auka þarf þekkingu og hæfni uppeldisaðila til þess að bregðist við vanlíðan ungmenna. Loks þarf að tryggja betra aðgengi að geðheilbrigðisþjónustu í samfélaginu og draga þannig úr líkum á að andleg vanlíðan á unglingsárum þróist á verri veg og ungmenni leiti til bjargráða eins og vímuefna til þess að deyfa hana.
Modalidades de retroalimentación correctiva escrita: estudio exploratorio de prácticas docentes en el aula de traducción
Authors: Andújar Moreno Gemma , Cañada Pujols Maria Dolors
Published: February 2022

La investigación sobre evaluación en la formación de traductores se ha centrado en el análisis del error y en la elaboración de baremos de corrección. Sin embargo, existen pocos trabajos empíricos sobre evaluación formativa y retroalimentación (feedback) en el aula de traducción. El objetivo de esta investigación es explorar las características de la retroalimentación correctiva escrita que reciben los estudiantes en tareas de evaluación en un contexto académico concreto. El análisis de un corpus con más de mil actividades corregidas por profesores de una universidad catalana ha permitido identificar cinco modalidades distintas. En general, la retroalimentación de los docentes es unidireccional, sobredimensiona el papel del error y se centra en la tarea, por lo que cabe preguntarse hasta qué punto su función es formativa.

Published: February 2022

After the accident at the Fukushima-1 NPP, the requirements for the safety of reactor facilities became more stringent, which led to the improvement of safety systems due to the transition from active principles of operation to safety systems with passive principles. An example of such a system is a passive heat removal system (hereinafter PHRS), which should transfer heat from the core of a nuclear steam generating unit to the final absorbers (sea water and/or atmospheric air) during normal and emergency cooling down, as well as when operating at low power static modes. without the participation of a steam turbine unit. Moreover, the process of heat removal should be carried out without using additional energy sources. This means that the PHRS must convert part of the removed heat energy into work on moving the coolant in it. Without the cost of electricity, this process can be carried out using natural circulation (EC) and/or steam-water jet devices (PVSA).

A shipboard nuclear power plant is a complex ergatic system that includes jointly interacting non-ergatic (technical) and ergatic (biological) elements. It is obvious that the reliability of the operation of the power plant will depend on the reliability indicators of all elements. Therefore, this article proposes a method for modeling the reliability of the functioning of a ship's nuclear power plant. It is based on the synthesis of technologies for the development of logical and probabilistic models of reliability of complex organizational and technical systems and methods for formalizing the processes of functioning of complex ergatic systems using probabilistic and algorithmic models of human operator activity.

Anti-yeast activity of endophytic fungi isolated from medicinal herb Ocimum sanctum with emphasis on Candida albicans
Authors: Mat Jalil Mohd Taufiq , Ibrahim Darah
Published: February 2022

Endophytic fungi, Lasiodiplodia pseudotheobromae IBRL OS-64 and Muscodor sp. IBRL OS-94 were previously isolated from the leaf of medicinal plant, Ocimum sanctum was screened for their anti-yeast activity against pathogenic yeast. Both fungal isolates were cultivated in submerged fermentation using yeast extract sucrose broth as culture medium enriched with plant water extract and incubated for 20 d at 30°C with an agitation speed of 120 rpm. Preliminary study via agar plug diffusion assay revealed that both fungal isolates possess a fair anti-yeast activity against three out of four test yeast including Candida albicans, C. utilis and Rhodotorula rubra. On the disk diffusion assay, the ethyl acetate extract of L. pseudotheobromae IBRL OS-64 and Muscodor sp. IBRL OS-94 showed significant anti-yeast activity with the size of the inhibition zone ranging in between 9.6±0.5 - 21.3±0.5 mm and 14.4±0.5 - 20.2±0.7 mm respectively. As for ethyl acetate extract from L. pseudotheobromae OS-64, the MIC and MYC values were in the range of 500 – 1000 μg/mL and 2000 – 8000 μg/mL respectively. On the other hand, the MIC and MYC values of ethyl acetate extract of Muscodor sp. OS-94 ranged between 250 – 500 μg/mL and 1000 – 4000 μg/mL respectively. The time-kill assay demonstrated that the growth of C. albicans cell was dose-dependent in which the extract concentration was lower and higher than the MIC value showing yeastostatic and yeastocidal effects respectively. The scanning and transmission electron microscopes observation revealed that the candidal cells expose to extract experienced severity of morphological deterioration which led to cell death beyond repair and thus suggesting that the fungal extract could be a potential anti-candidal agent.

Purpose: To report our experience with the use of Levomepromazine (LMZ) for the treatment of delirium in patients treated for Acute Respiratory Distress Syndrome (ARDS) due to COVID-19. Methods: Retrospective series of patients admitted to the Intensive Care Unit (ICU) of a non-academic hospital and who requiring invasive mechanical ventilation for the treatment of ARDS due to SARS-CoV-2. Infection was confirmed by Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) testing, and patients presented delirium after withdrawal of neuromuscular blockade or sedation lightening treated with LMZ on top of other treatment. Results: Out of 34 ARDS patients admitted from 22 March 2020 to 23 January 2021, 11 (32.3%) died before neuromuscular blockade withdrawal, and of the remaining 23, 16 were treated with LMZ. The median time to initiation of LMZ was 6 days (interquartile, 5 to 8) from the start of sedation, and median duration of LMZ treatment was 5 (1 to 28) days. Median sedation score (as assessed by the Sedation Agitation Scale (SAS)) was 2 (1-4) at initiation and 3 (2-4) at discontinuation of LMZ, while median analgesia scores (Behavioral Pain Scale (BPS)) were respectively 3 (3-5) and 4 (3-5). Of the 16 patients treated with LMZ, 12 were weaned from mechanical ventilation immediately following discontinuation, without recurrence of delirium. No adverse effects related to LMZ use were observed. The 4 patients who could not be weaned from mechanical ventilation following LMZ required new neuromuscular blockade. Conclusions: Based on this retrospective series, LMZ seems to be useful for the management of delirium occurring after withdrawal of neuromuscular blockade or lightening of sedation in patients with ARDS due to SARS-CoV-2.

En países pobres y/o periféricos, con un frágil sistema de seguridad social, el trabajo en personas viejas ocurre como única forma de subsistencia económica que permite mantener las condiciones materiales de la vida. En este contexto, se fuerzan formas precarizadas de trabajo asalariado formal o informal que no alcanzan para un estándar de vida digna. Esta investigación analizó representaciones y narrativas sobre el trabajo en la vejez que se construyen en medios de comunicación y redes sociales en Chile.

The National Democratic Party's strategy in facing the 2019 Election with an open proportional representation system is to recruit celebrities as voters. Their placement as candidates for state administrators risks injuring the substance and objectives of democracy, because candidates for state administrators must have certain ideologies and competencies as well as the replacement of ideological cadres by celebrities. This qualitative research uses the literature study method for data collection. The purpose of this study is to find out the pragmatism of the national democratic party in an open proportional electoral system. From the results obtained, political parties tend to leave ideological cadres rather than representing members and the wider community. The Nasdem Party finally saw that celebrities are part of professional actors who have the ability as celebrity politicians although in practice they play more roles as celebrity endorsers. Placement of celebrities as candidates for state administrators is a necessity for sales-oriented parties. However, it is necessary to consider the risks to the aims and substance of democracy.

The Job Creation Act (Omnibus-Law) contains several policies that have led to a protest movement in the form of demonstrations related to this regulation. The demonstration was widely covered by online news media in Indonesia. The research method used is qualitative by using news articles as the unit of analysis using the Entman model framing paradigm to see how online news media construct reality. This study focuses on the news of demonstrations against The Job Creation Act reported by Tirto.id and Liputan6.com for October 2020. The purpose of this research is to reveal how Tirto.id and Liputan6.com portrayed the demonstrations as the reflection of democracy in Indonesia. The results show that Tirto.id and Liputan6 have differentiation in interpreting this phenomenon. Tirto.id prioritizes a critical attitude to issues related to reflection of democracy in Indonesia in that context, that in the democratic process, there is still violence from the apparatus, annihilation of workers, and riots that cause damage to facilities and infrastructure. Meanwhile, Liputan6.com tends to develop a positive perspective regarding the democratic process during and after demonstrations. Despite violence against journalists, the authorities are still trying to resolve the case and emphasize the government's positive efforts in improving the country's economy through the Job Creation Law.

The present field experiment was aimed to evaluate the tolerance level to shoot, fruit borer infestation, and yield traits with 174 brinjal accessions at the University orchard, Department of Vegetable crops, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore. Among the evaluated accessions, the Acc- EC 490062, Acc - EC 144139-D and Acc - IC 344646 were identified as the best performers as they showed favorable effects for earliness to flowering and harvest, number of fruits per plant and yield. In addition, they recorded the lowest level of shoot and fruit borer infestation with a high marketable yield. The least incidence of shoot borer (13.97 %) was registered in the accession EC 144139-D, EC 490062 (14.35 %), followed by the accession IC 344646 (15.74 %). Whereas the minimum infestation of fruit borer was recorded by the accessions EC 490062 (13.18 %), EC 144139-D (13.52 %), and IC 344646 (13.67 %). The maximum marketable yield per plant (3.46 kg) was registered by the Acc - EC 490062 followed by Acc - EC 144139-D (3.80 kg) and Acc- IC 344646 (3.64 kg). The genotypes acknowledged in the current investigation can be explored as parents in future crop improvement programmes of brinjal.

Published: February 2022

Background

To evaluate the association between home-based neonatal care interventions and the incidence of maternal health conditions as well as to estimate the longitudinal trend of the incidence of maternal health conditions over 13 years in 39 villages of the field program area of the of home-based neonatal care from rural Gadchiroli, India.

Methods

This was a before-after comparative analysis of a program implemented in thirty-nine villages in Gadchiroli, India. The home-based newborn care interventions were incrementally introduced during the field trial (1995 – 1998) and continued as a service program until 2008. Over thirteen years (1995–2008), pregnant women were recruited and followed up from the seventh month of pregnancy to 28 days postpartum by trained female community health workers who made antenatal, natal and post-natal home visits, provided health education to mothers for behavior change, managed normal and sick neonates as well as encouraged seeking medical care when necessary. They recorded maternal symptoms and signs, which a physician supervisor verified. Based on these symptoms and signs, a computer algorithm diagnosed 20 different maternal health conditions. The incidence of these conditions in the first year (1995-96) was compared with the intervention’s last two years (2006 - 2008).

Result

The mean coverage of home-based newborn care, assessed on eight indicators, increased from 48.5% in 1995 – 96 to 87.1% in 2006 – 08. The proportion of women with any maternal health conditions during pregnancy reduced by 44.76% (P<0.001), during labor by 44.59% (P <0.001) and during the postpartum period by 77.82% (P<0.001). The mean number of maternal conditions per 100 women reduced by 69% (P<0.001). The need for emergency obstetric care was reduced by 78.83% (P<0.001). The proportion of women free of any maternal health condition increased from 32.9 % to 64.6 %.

Conclusions

Home-based neonatal care interventions were associated with a significant reduction in the incidence of maternal health conditions. Developing a dedicated package of home-based maternal care in combination with neonatal care may further improve maternal health.

Published: February 2022

Background

Population based studies to understand the current healthcare seeking behavior of the population for pain in back and extremities are lacking from rural India. We studied: (i) healthcare seeking behavior for pain in back and extremities, (ii) types of care providers sought by the community, and the (iii) factors associated with treatment seeking.

Methods

Two villages were randomly selected from a cluster of 39 villages in the Gadchiroli district of India. Using predetermined criteria, all resident adults ≥ 20 years, were surveyed in January 2010 by the trained community health workers (CHW) by making household visits. Using a structured, pretested questionnaire, they inquired and recorded the history of pain in back and extremities and health care seeking for the same during the previous 12 months.

Results

Out of 2535 eligible adults in two villages, 2259 (89%) were interviewed. A significant proportion of the participants with back pain and pain in the extremities sought treatment (86.99%). The maximum number of individuals sought care from private providers (64.64%) followed by home remedies (61.64%), government facilities (17.03%), community health workers (CHW) of Society for Education, Action and Research in Community Health (SEARCH) (12.87%), Bengali doctors (5.7%) and traditional healers (6.56%). Almost equal number of participants with any back pain (88.88%) and any extremity pain (88.95%) sought treatment. The care seeking was significantly more for female participants (odds ratio, OR=1.83, 95% confidence interval, CI=1.32–2.5), in case of severe pain (OR=2.0, 95% CI=1.29–3.12) and in the age group 51 to 60 years (OR=2.04, 95% CI=1.14–3.67).

Conclusions

A significant number of the individuals with back pain and pain in the extremities in rural Gadchiroli seek care, mainly from private practitioners and resort to application of home remedies whereas the care seeking from the public health facilities is considerably less. Hence there is need to provide care for pain in back and extremities in the public healthcare system.

Published: February 2022

Background

Evidence suggests that substance use remains one of the negative consequences of the coronavirus (COVID-19) pandemic among older adults. However, not much is known about the prevalence and associated factors of substance use during the COVID-19 pandemic in Ghana.

Methods

Using data from a survey on coronavirus-related health literacy conducted in the Ashanti Region of Ghana among 474 older adults aged 50 years or above, we performed multivariable logistic regression analysis to assess demographic, socio-economic and health-related correlates of alcohol and tobacco use.

Results

We recorded a prevalence of 11.4% alcohol use and 6.8% of tobacco smoking, in addition to 16% prevalence of tobacco smoking and/or alcohol intake during the pandemic. After adjusting for the demographic and socio-economic factors, male participants had higher odds of substance use than their female counterparts. Older adults with tertiary education and those who rated their wealth status as poor had a lower odds of substance use than their counterparts.

Conclusions

Our findings have implications for designing programs and policies to limit substance use among older adults during the COVID-19 pandemic and possible future disease outbreaks.

Published: February 2022

Background

The ongoing coronavirus disease 2019 (COVID-19) pandemic has disrupted essential health services globally. COVID-19 related disruptions threaten malaria control and elimination as untreated and inappropriately treated malaria cases can lead to excess mortality and impede the COVID-19 response. This study characterized malaria service provision during the pandemic in Manicaland Province, Zimbabwe.

Methods

A cross-sectional survey was conducted in randomly selected health facilities in Buhera, Makoni, and Mutare districts in August 2020. Data on the provision of malaria services, the availability of infection prevention control measures and the display of COVID-19 related information, education, and communication (IEC) materials were collected using a standardized questionnaire. Descriptive analyses by facility type, managing authority, and district were used.

Results

A total of 100 health facilities were surveyed and most were publicly managed health centers and clinics. 5% of health facilities reported testing for COVID-19, 3% reported COVID-19 related health worker absences and 1% reported disruptions to any essential health services. About two-thirds (67%) of facilities displayed COVID-19 related IEC materials and 75% had infection prevention control measures available. Despite inequities in malaria readiness by managing authority, district, and type of facility, 70% of facilities were considered “ready” to provide malaria services.

Conclusions

Malaria services were fairly available with very few COVID-19 related disruptions to essential health services. Maintaining essential malaria services remains crucial in preventing excess malaria morbidity and mortality.
