A low-cost culture- and DNA extraction-free method for the molecular detection of pneumococcal carriage in saliva.

Molecular methods have improved the sensitivity of the detection of pneumococcal carriage in saliva. However, they typically require sample culture enrichment and nucleic acid extraction prior to performing the detection assay and may limit scalability for extensive surveillance of pneumococcus, particularly in low-resource settings. We evaluated the performance of a DNA-extraction-free method for the detection of pneumococcus in saliva. We developed a streamlined qPCR-based protocol for the detection of pneumococcus, omitting culture enrichment and DNA extraction. Using saliva samples collected from children attending childcare centers (New Haven, CT, USA), we evaluated the detection of pneumococcus using saliva lysates as compared to purified DNA extracted from culture-enriched aliquots of the paired samples using qPCR targeting the pneumococcal piaB gene. Of the 759 saliva samples tested from 92 children [median age 3.65 years; IQR (2.46-4.78)], pneumococcus was detected in 358 (47.2%) saliva lysates prepared using the extraction-free protocol and in 369 (48.6%) DNA extracted from culture-enriched samples. We observed near-perfect agreement between the two protocols (Cohen's kappa: 0.92; 95% CI: 0.90-0.95). Despite a high correlation between CT values generated by the two methods (r = 0.93, P < 0.0001), the CT values generated from saliva lysates were higher (lower concentration) than those from culture-enriched samples (ΔCT = 6.69, P < 0.00001). The cost of detecting pneumococcus using saliva lysates was at least fivefold lower (US$2.53) compared to the cost of the culture-enriched method (range: US$13.60-US$19.46). For pneumococcal carriage surveillance in children, our findings suggest that a DNA extraction-free approach may offer a cost-effective alternative to the resource-intensive culture-enrichment method.IMPORTANCESurveillance for carriage of pneumococcus is a key component of evaluating the performance of pneumococcal vaccines and informing new vaccination strategies. To improve the scalability of pneumococcal carriage surveillance, we show that molecular detection of pneumococcus in saliva from children can be performed without culture enrichment and DNA extraction. Our findings show that using the extraction-free method can improve surveillance efforts for pneumococcal carriage in children, overcoming the resource-intensive hurdle that comes with the use of molecular methods, particularly in low-resource settings.

Infection Rates and Symptomatic Proportion of SARS-CoV-2 and Influenza in Pediatric Population, China, 2023.

We conducted a longitudinal cohort study of SARS-CoV-2 and influenza rates in childcare centers and schools in Wuxi, China, collecting 1,760 environmental samples and 9,214 throat swabs from 593 students (regardless of symptoms) in weekly collections during February-June 2023. We estimated a cumulative infection rate of 124.8 (74 episodes)/1,000 persons for SARS-CoV-2 and 128.2 (76 episodes)/1,000 persons for influenza. The highest SARS-CoV-2 infection rate was in persons 18 years of age, and for influenza, in children 4 years of age. The asymptomatic proportion of SARS-CoV-2 was 59.6% and 66.7% for influenza; SARS-CoV-2 symptomatic proportion was lower in 16-18-year-olds than in 4-6-year-olds. Only samples from frequently touched surface tested positive for SARS-CoV-2 (4/1,052) and influenza (1/1,052). We found asynchronous circulation patterns of SARS-CoV-2 and influenza, similar to trends in national sentinel surveillance. The results support vaccination among pediatric populations and other interventions, such as environmental disinfection in educational settings.

COVID-19 School Closures Were Associated With A Decline In Employment For Female Nurses With Young Children.

COVID-19-related school closures may have had unintended consequences affecting the ability of health professionals with school-age children to work-particularly female professionals, who often have disproportionate child care responsibilities. We combined labor-force participation data from the Current Population Survey with measures of school closures based on cell phone mobility data to examine the association between local school closures and labor supply among female nurses during the COVID-19 pandemic. During the six months after large-scale closure of schools at the end of the 2019-20 school year (March-August2020), among counties with above-median school closure rates, the employment rate of female nurses with young children declined by 12.5percentage points versus the rate during the prior four months (November2019-February2020); the change in the employment rate in below-median counties was not statistically significant. No statistically significant changes were observed among female nurses who had only older children or among male nurses. During public health emergencies, policies should consider how disruptions to schooling may affect the labor supply of health care professionals. Strategies might include direct provision of child care by health care facilities, subsidies and other aid to child care centers, or subsidies to health care workers for affordable child care.

The impact of an early childhood educator e-Learning course on young children’s fundamental movement skills: A cluster randomized controlled trial

ABSTRACT Early childhood educators (ECEs) are ideally positioned to support the development of children’s fundamental movement skills (FMS). However, ECEs have little specialised training to support the development of FMS in young children. This study aimed to assess the impact of an e-Learning course on the FMS of preschool-aged children. 145 Preschool-aged children and 42 ECEs from 12 childcare centres participated in the study. ECEs in the experimental group were asked to complete the e-Learning course. A subsample of children (n = 48) was objectively assessed using the Test of Gross Motor Development 3rd Edition (TGMD-3). Additionally, parents of all participating children reported perceptions of their child’s FMS to understand if they knew how well their child was progressing. Findings showed a significant increase in TGMD-3 assessed locomotor skills from baseline to follow-up in the intervention group compared to the control group and total FMS but not objective control skills. Parent-reported FMS increased in the intervention group for all locomotor, object control skills, and total FMS. However, the intervention effect for all three measurements was not significant. The results from this study highlight the potential utility of online professional development for ECEs as an approach to improving young children’s FMS.

Female Employment and Economic Integration in Central America

ABSTRACT: Extensive literature has shown that women’s employment contributes to increasing rates of household savings and economic growth. Likewise, evidence has been reported that in an economic integration scheme, such as that of Central America, the strong economic interdependence existing between countries, because of their relatively high trade flows of imports and exports, gives rise to the spread of economic developments occurring in a country. This paper investigates the extent to which the increase in female employment in the countries of the Northern Triangle of Central America (Guatemala, El Salvador, and Honduras) leads to the increase in growth rates in the other countries (Nicaragua, Costa Rica, and Panama). For this purpose, principal components, which is a data compression methodology, is used. The variables that are included in the vector of principal components are the female-to-male employment ratios in the industrial sectors of the Northern Triangle countries. All data used in the analyses were taken from the World Bank’s World Development Indicators. The first principal component of these variables explains 77 percent of the variance, and its decrease represents the deindustrialization of the respective countries. The second principal component accounts for 17 percent of the variance, and its increase represents the expansion of the service sector in the countries. The estimation of error correction equations showed that the first principal component of the female-to-male employment ratios of the industrial sector in Guatemala, El Salvador, and Costa Rica, exerted positive impacts on the economic growth rates of Nicaragua, Costa Rica, and Panama, while the second principal component exerted negative impacts. The results also showed that the ratios of female to male industrial employment, as well as the first principal component, fell as tariffs on imports were reduced, reflecting a process of deindustrialization which has led to losses in economic growth, and a decrease in trade flows, and rising youth unemployment and increases of the underground economy with adverse impacts on productivity. Likewise, trends towards economic stagnation and rising unemployment have led to increases in irregular emigration and remittances. Another important result is that the process of deindustrialization, fueled by the extreme openness of economies, has generated a substantial increase in the homicide rate. In summary, the results show that female employment generates increases in the economic growth rate of the respective country and in the other member countries. However, this process of regional employment induction is undermined by the extreme openness of economies, which means that the main beneficiaries of the economic dynamism imparted by the increase in female employment may be the countries from which it is imported. In other words, “globalization” or “openness” frustrates national efforts at economic and social development. It should be noted that in the 1960s and 1970s, when the model of import substitution prevailed, the Central American economies grew at rates twice as high as those prevailing after the “reforms.” The economic policy recommendations are based on the promotion of women’s employment by increasing the levels of female schooling, the establishment of national networks of childcare centers, combating discrimination against women in the workplace, etc. Efforts to increase women’s employment will be better developed if they are structured within the framework of a national/regional employment strategy, in which objectives and targets would be established for each country, and the actions to be carried out in the areas of obtaining resources, identifying, approving and supervising projects would be outlined, and the results goals would be established with the respective indicators to be achieved in the medium and long term. But it should be pointed out that these actions cannot yield the results sought in the current structure of extreme openness of economies, which makes it necessary to design and implement policies to achieve the reindustrialization and re-agriculturalization of the economies, seeking, in addition to increasing economic dynamism, the increase of quality employment, and the reduction of violence and irregular emigration, the achievement of self-sufficiency and sustained increases in the production of goods of special importance. The results of this work have shown that in efforts to reignite economic growth, women’s employment and Central American economic integration can play important roles.

Changes in the importance and performance of low-sodium management among childcare center cooks in Yongin, South Korea, after salinometer support programs: a descriptive study

Objectives: This study aimed to evaluate the importance and performance of sodium reduction practices among childcare center cooks in the Yongin area before and after a 3-month salinometer support program. Methods: In total, 313 cooks employed in childcare centers in Yongin were surveyed before and after participating in a salinometer support program. The survey included questions on general information, sodium-related dietary habits, and perceived importance and performance levels of sodium reduction approaches in the purchasing, cooking, and serving areas. The centers were divided into childcare centers registered as group-feeding facilities (FS group, n = 68) and those not registered as such (non-FS group, n = 245). The differences between the two groups were analyzed. Results: The overall importance levels increased significantly after the program in both the FS-group (P &lt; 0.001) and non-FS group (P = 0.005). The overall performance levels also increased significantly in both groups (P &lt; 0.001 for all). Consequently, the significant difference between the importance and performance levels disappeared in both groups after the program. However, unlike the FS group, which showed no significant differences between the importance and performance levels after the program in all three areas, the non-FS group still demonstrated lower performance levels than importance levels in the purchasing (P = 0.011) and serving (P = 0.034) areas after the program. Conclusions: The use of salinometers significantly enhanced the performance and importance of low-sodium management practices among cooks in childcare centers, especially in the FS group. The continuous monitoring of salinity measurements and tailored education specialized for the FS and non-FS groups are recommended.

Genetic screening of newborns for deafness over 11 years in Beijing, China: More infants could benefit from an expanded program.

Genetic screening of newborns for deafness plays an important role in elucidating the etiology of deafness, diagnosing it early, and intervening in it. Genetic screening of newborns has been conducted for 11 years in Beijing. It started with a chip to screen for 9 variants of 4 genes in 2012; the chip screened for 15 variants of those genes in 2018, and it now screens for 23 variants of those genes. In the current study, a comparative analysis of three screening protocols and follow-up for infants with pathogenic variants was performed. The rates of detection and hearing test results of infants with pathogenic variants were analyzed. Subjects were 493,821 infants born at 122 maternal and child care centers in Beijing from April 2012 to August 2023. Positivity increased from 4.599% for the chip to screen for 9 variants to 4.971% for the chip to screen for 15 variants, and further to 11.489% for the chip to screen for 23 variants. The carrier frequency of the GJB2 gene increased from 2.489% for the chip to screen for 9 variants and 2.422% for the chip to screen for 15 variants to 9.055% for the chip to screen for 23 variants. The carrier frequency of the SLC26A4 gene increased from 1.621% for the chip to screen for 9 variants to 2.015% for the chip to screen for 15 variants and then to 2.151% for the chip to screen for 23 variants. According to the chip to screen for 9 variants and the chip to screen for 15 variants, the most frequent mutant allele was c.235delC. According to the chip to screen for 23 variants, the most frequent mutant allele was c.109G>A. The chip to screen for 15 variants was used to screen 66.67% (14/21) of newborns with biallelic variants in the SLC26A4 gene for newly added mutations. The chip to screen for 23 variants was used to screen 92.98% (53/57) of newborns with biallelic variants in the GJB2 gene (52 cases were biallelic c.109G>A) and 25% (1/4) of newborns with biallelic variants in the SLC26A4 gene for newly added mutations. Among the infants with pathogenic variants (biallelic variants in GJB2 or SLC26A4), 20.66% (25/121) currently have normal hearing. In addition, 34.62% (9/26) of newborns who passed the hearing screening were diagnosed with hearing loss. Findings indicate that a growing number of newborns have benefited, and especially in the early identification of potential late-onset hearing loss, as the number of screening sites has increased. Conducting long-term audiological monitoring for biallelic variants in individuals with normal hearing is of paramount significance.

Associations Between Administrative Burden and Children’s ECE Stability During the Covid-19 Pandemic

The Covid-19 pandemic caused widespread closures of early care and education (ECE) facilities that negatively impacted children’s socioemotional, behavioral, and academic development. Policies permitting child care centers to remain open by obtaining waivers from closure directives involved varying levels of administrative burden. This study examined administrative burden within waiver policies and its association with ECE stability, as measured by children’s enrollment in waiver-obtaining child care centers. I found Black children were significantly less likely than White children to be enrolled in a waiver-obtaining center, and also far less likely to have a center that obtained a waiver very early on in the pandemic. Analyses showed rates of enrollment in waiver-obtaining centers were far lower among children whose centers experienced more administrative burden, and suggested racial disparities in ECE stability were driven by Black children’s concentrated residence in communities where the waiver application process was more burdensome.

Psicanálise e saúde mental infanto-juvenil: uma reflexão sobre o lugar da subjetividade nos CAPSi

The aim of this article is to discuss the work of the mental health teams in the Child and Adolescent Psychosocial Care Centers (CAPSi), in order to consider subjectivity as a factor of inclusion. The methodology used was based on applied psychoanalysis. Franco Basaglia's contributions were revisited in order to understand his influence on the Psychiatric Reform in Brazil and to elucidate the current practice of CAPSi. The current impasses in the field of subjectivity in the Psychiatric Reform are discussed and it is proposed to locate transversal surfaces that articulate the presence of a psychoanalytic approach to subjectivity in psychosocial care. The conclusion is that it is important to discuss a psychoanalytic approach to subjectivation in public mental health services, so that treatment in these services is not polarized between biological reductionism and psychosocial care.

Fostering Play in the COVID Crisis: Insights from Infant-Toddler Teachers

AbstractPlay is pivotal in supporting young children’s holistic development. The COVID-19 crisis further highlighted the importance of play in supporting children’s well-being and in providing a sense of normalcy. Guided by the phenomenographic method, this study aimed to examine Korean in-service infant-toddler teachers’ experiences in fostering play in early childhood educational classrooms during the COVID-19 crisis. The study involved 10 infant-toddler teachers working with children under the age of three years at a large university-based childcare center. They participated in drawing tasks and in-person focus group interviews. The findings revealed that the pandemic caused and exacerbated barriers to everyday play. However, despite challenges, the participants demonstrated their strong commitment to play in the classroom, exhibiting resilience, adaptability, creativity, and resourcefulness. They continued to create a playful environment, support play in various forms, and prioritize play-based learning, demonstrating their strong commitment to play. One notable change expressed by the participants was limited social interaction during mealtime. This study found that the much-needed, unavoidable public health interventions during the COVID-19 crisis may have resulted in unintended consequences for infants’ and toddlers’ social-emotional and language development. Such findings reinforce the idea that play should remain at the forefront of education during the pandemic and beyond.

Source Identification Using Principal Component Analysis and Health Risk Assessment of Heavy Metals Contamination in PM2.5 Near an Industrial Area in Thailand

AbstractIndustrialization has led to a surge in air pollution-related problems, as particulate matter (PM) containing heavy metals poses significant health risks. Understanding airborne particle chemistry, particularly the presence of heavy metals, is vital for effective air quality management and health interventions. This study analysed heavy metal levels in PM2.5 across various sites near an industrial zone in Thailand, including areas near main roads, the industrial zone, as well as indoor and outdoor areas of childcare centres. The concentrations of ambient PM2.5 were found to exceed national standards and acceptable limits during the cool dry season, particularly in the industrial zone (46.4 µg/m3), followed by areas near main roads (41.0 µg/m3) and childcare centres (31.6 µg/m3). The impact of the indoor–outdoor relationship on PM2.5 concentration within childcare centres varied. During the cool dry season, Aluminium had the highest concentration, while lead (Pb) across all sites raised environmental concerns. Remarkably, indoor childcare centres showed higher Pb levels than industrial zones and areas near the main road. Principal Component Analysis revealed the distinct factors linked to specific metals, implying contributions from industrial and transportation sources. Lead isotopic analysis indicated potential associations between lead sources and industries like smelting and refining. During the cool dry season, non-carcinogenic risks were concerning (HI &gt; 1), especially near roads and industrial areas. Vulnerabilities were also observed in students and teachers within indoor childcare centres. This study underscores the importance of monitoring and reducing heavy metal pollution in PM2.5, especially in childcare centres near industrial zones, to preserve public health and regional air quality.

Examining the Stability and Durability of Child Care Arrangements during the COVID-19 Pandemic in Canada

La pandémie de COVID-19 a provoqué d'importantes perturbations dans tous les secteurs du travail et de la vie familiale, y compris les services de garde éducatifs à l'enfance (SGÉE). Les recherches démontrent que l'instabilité (soit les interruptions aux services de garde) et l'absence de durabilité des SGÉE (soit le maintien des mêmes services de garde au fil du temps) peuvent exacerber le stress des parents et nuire au développement de l'enfant. S'inspirant des données d'un sondage original réalisé en décembre 2020 auprès de 882 parents de jeunes enfants de quatre provinces canadiennes, les autrices ont examiné les choix des parents au sujet de la garde d'enfants avant la pandémie et les répercussions de la COVID-19 sur ces dispositions, dans l'immédiat et à long terme. Dans leur échantillon, elles ont trouvé que a) les services hors du domicile étaient plus instables et plutôt moins durables que ceux à domicile; b) la perte d'accès pendant la pandémie à cause de la fermeture des centres de la petite enfance était moins marquée en Colombie-Britannique, ce qui était toutefois contrebalancé par un taux relativement élevé de retraits volontaires; c) l'Ontario a présenté un taux relativement élevé de pertes d'accès en raison des fermetures et des retraits volontaires; d) dans l'ensemble, 64 % des dispositions en matière de garde se sont révélées durables, mais e) la durabilité était plus faible dans les familles à plus faible revenu et en Ontario. En revanche, la durabilité était beaucoup plus élevée au Québec, ce qui fait ressortir le rôle possible des investissements dans les politiques des SGÉE pour protéger les parents et les enfants en cas d’événements déstabilisants.

LEGAL REQUIREMENTS OF HOME-BASED CHILDCARE CENTRES IN MALAYSIA; ARE CHILDCARE PROVIDERS AWARE?

Home-based childcare (HBCC) services are among the childcare services available in Malaysia, as ensconsced in the Child Care Centre Act 1984. In Malaysia, HBCC providers are only allowed to care for a minimum of four and a maximum of 10 children. However, this definition does not include small home-based childcare services or childminders who care for less than four children. Employing the qualitative method of content analysis, this study discusses the laws and regulations governing HBCC in Malaysia, particularly the legal requirements that need to be fulfilled. This is further supported by interviews conducted with childcare providers who look after children at their home to examine their level of understanding of the legal requirements under Malaysian childcare laws and regulations. Findings indicate, among others, that the HBCC operators are unaware of the need to register with the Social Welfare Department. The adherence to the legal requirements for this HBCC should not be taken lightly, as it is crucial to ensure the safety and well-being of children. Consequently, greater efforts are required to ensure the children's health and safety because the current procedures rely solely on the experience and expertise of the childcare providers. This paper contributes to the extent of knowledge of HBCC in Malaysia especially towards policy makers, child care operators and parents by exploring the experiences of HBCC childcare providers. It is proposed that continuous improvements need to be made to the laws and regulations on HBCC in ensuring high quality services of HBCC.

Importance of Human Breast Milk in the Early Colonization of Streptococcus mutans.

Background and objectives: The development of the oral microbiome begins in the prenatal stage. Breast milk contains antimicrobial proteins, microorganisms, metabolites, enzymes, and immunoglobulins, among others; therefore, differences have been noted in the type of microorganisms that colonize the oral cavity of children who are breastfed compared to those who are formula-fed. Our objective was to establish the relationship between breastfeeding, formula feeding, or mixed feeding (breastfeeding and formula) with the presence of S. mutans in a population of children under 6 months of age. Materials and Methods: The patients were recruited from the Child Care Center of Ciudad Juárez, Chihuahua, and from the pediatric dentistry postgraduate clinics of the Autonomous University of Ciudad Juárez; children exclusively fed maternally, with formula, and/or mixed were included. Those who had been fed within the previous hour were excluded. The sample was taken with a smear of the jugal groove using a sterile micro-brush. For the identification of Streptococcus mutans, a culture of Mitis Salivarius Agar (Millipore) was used. Results: 53.3% corresponded to females and 46.7% to males, 36.7% corresponded to maternal feeding, 23.3% corresponded to formula feeding, and 40% corresponded to mixed feeding. In 90% of the infants, the parents indicated that they did not perform oral hygiene. The CFU count showed that infants who were exclusively breastfed had an average of 9 × 10 CF/mL, formula-fed infants had an average of 78 × 10 CFU/mL, and those who had mixed feeding 21 × 10 CFU/mL. Conclusions: According to the results obtained, it was possible to corroborate that exclusive breastfeeding limits the colonization of Streptococcus mutans compared to those infants who receive formula or mixed feeding; these results could have a clinical impact on the dental health of infants by having a lower presence of one of the main etiological factors involved in dental caries and the type of microbiome established in the oral cavity.

The childcare director’s role in preventing burnout: a positive-psychological examination of the caregivers’ lived experience

ABSTRACT This study applied a positive-psychological approach to examining childcare directors’ role in maintaining the stability of their staff from the caregivers’ and directors’ points of view. Most of the childcare centers in Israel are characterized by high burnout and turnover of staff members. Nevertheless, some teams stay stable, and turnover is minimal. This study explored the factors using 30 semi-structured interviews with childcare center directors and caregivers regarding their occupational stability. Findings suggested that the sense of belonging to the childcare center was one source of stability. The director acted as a safe haven, maintaining the caregivers’ wellbeing. Other success factors are related mainly to their relations with other staff members, with the director, and with the children, and also to proper management that provides professional training and treats them with respect. The study’s contribution is fourfold. First, it gives voice to a population of women who work under difficult conditions for low pay. Second, it highlights the role of the childcare director in maintaining staff stability. Third, implementing its findings is relevant to creating and improving models of training and supervising early childhood educators. Fourth, studying anti-burnout factors can strengthen teams and provide the children with positive relationships with significant others.

Developmental trajectories of children's playfulness in two- to six-year-olds

Even though playfulness has been found to be highly relevant to the development and wellbeing of young children, hardly any longitudinal findings are available on stability and changes in children's playfulness. This study examined developmental trajectories of children's playfulness in two- to six-year-olds over a two-year period and analyzed whether individual and family characteristics and transition to primary school explain these trajectories. The sample included 839 children (47.3% girls, MAge = 4.87 years, SDAge = 1.39) from 38 childcare centers and 47 kindergartens in Switzerland. Children's playfulness was assessed at three measurement time points at one-year intervals using the multidimensional Children's Playfulness Scale to gather parent and teacher reports. Second-order linear growth curve models showed significant interindividual differences in children's playfulness at initial baseline. These differences correlated with effects for age, migrant background, and maternal education. The growth-related processes varied depending on children's age, and the individual dimension of children's playfulness whether an increase, stability, or decline was observed. In particular, social components of playfulness were found to change. On average, children's playfulness increased in early years but decreased from school age onwards. However, closeness in parent–child relationships proved to be supportive of children's playfulness at all time points. The results indicate the significance of positive parenting to children's playfulness, but they also draw attention to how playful qualities can be maintained and more highly valued in the school environment. In general, the study can contribute to a better understanding of the construct of playfulness in childhood.

A micro-political exploration of the resignation of Hong Kong experienced kindergarten principals amidst preschool education coordinator turnover

The early childhood education system in Hong Kong operates within a corporate governance framework. However, there is a lack of research on the interaction between principalship and corporate governance in kindergartens and childcare centres. This study aims to address this gap by examining how a preschool education coordinator (PEC), working under corporate governance principles in a non-governmental organization (NGO), influenced the resignation decisions of principals. Using micro-political theory, this study examines power dynamics, conflicts, and decision-making processes that led to principals’ resignations. This phenomenological case study utilized a focus group discussion with three principals who had resigned from the NGO. Through thematic analysis, three key themes emerged from the study: changing governance and accountability, conflicting educational values and beliefs between the preschool education coordinator and the principals, and contrasting leadership behaviours and styles. The findings of this study have significant implications for the local community, as well as offering valuable insights that can inform and benefit international audiences interested in early childhood education leadership development and human resources management. As early childhood education systems worldwide grapple with similar challenges, understanding the relationship between corporate governance and principalship can help devise strategies for enhancing organizational effectiveness and ensuring principal retention.

BUILDING PERFORMANCE ANALYSIS OF CHILDCARE CENTERS IN KOREA FOR RETROFIT DESIGN: TYPOLOGY BASED STUDY ON ENERGY PERFORMANCE

ABSTRACT This study investigates different architectural types of Korean national childcare centers. The goal of this study is to provide a preliminary study of the energy retrofit of childcare centers. Given the growing concern over climate change, renovation and remodeling of current buildings for energy use improvement has become a major movement. Thus, today’s improvement in the building environment inevitably accompanies energy use improvement. An examination of 17 childcare centers in the Dongdaemon-gu district in Korea has been carried out. This includes the history of the buildings, construction information and energy use of the buildings. The cases are classified depending on their architecture type and have been analyzed with their energy use. Korea has embraced the influence of other countries with child care policies and types. The typology has been adapted to the Korean environment. This research is the preliminary study for green renovation of national childcare centers under a Korean context.

Observed relationships between nap practices, executive function, and developmental outcomes in Tunisian childcare centers

The objective of this design was to conduct an observational study comparing anthropometric characteristics, cognitive functions, as well as gross and fine motor skills. The study included 118 preschool-aged children (47 boys, 71 girls) enrolled in childcare centers. They were categorized into two groups based on their nap habits. The nap group comprised 59 children (23 boys, 36 girls), age (mean ​± ​standard deviation) ([3.96 ​± ​0.54] years) who took naps after lunch, while the no-nap group included 59 children (24 boys, 35 girls) age (mean ​± ​standard deviation) ([4.18 ​± ​0.61] years) who remained awake during this period. The results showed that the napping group had significantly higher scores for body mass index (BMI) (p ​< ​0.000 1), height-for-age z score (HAZ) (p ​= ​0.003), and higher BAZ (BMI-for-age z score) scores (p ​< ​0.000 1), compared to the No-nap group. In terms of cognitive function, the study revealed that the napping group had better working memory performance compared to the No-nap group (p ​= ​0.002), but no significant impact on inhibition was observed. The results also showed that taking a nap may improve functional mobility (p ​= ​0.003) and upper body strength (p ​= ​0.026) especially in boys. Future research could investigate the long-term effects of inadequate nap time on children's health and development and also develop and evaluate interventions to improve nap time habits in preschool children.

Indoor Air Quality and Sick Building Syndrome among Caretakers in Childcare Centers

Sick Building Syndrome (SBS) refers to the health-related symptoms of exposure to an unhealthy microenvironment, especially poor indoor air quality This study investigated the associations of indoor air quality including particulate matter (PM10 and PM2 5), Carbon Dioxide (CO2), Carbon Monoxide (CO), Total Volatile Organic Compounds (TVOCs), and childcare center environment with SBS symptoms among caretakers. SBS was assessed using a self-reported questionnaire The prevalence of SBS was 77 78% among caretakers PM10 negatively correlated with CO2 (r=0 -558; p&lt;0 01) PM10 levels were associated with any reported symptoms of SBS (OR=7 38; 95%CI 1 98 - 27 53), and upper respiratory symptoms (OR= 12 00; 95%CI 1 46 – 98 08) PM2 5 showed no association with SBS Using air refresher was associated with upper respiratory symptoms (OR=5 10; 95%CI 1 46 – 13 59), lower respiratory symptoms (OR=3 64; ; 95%CI 1.22 - 10.82).
