영유아교사의 놀이성과 공감능력이 놀이지원역량에 미치는 영향

The purpose of this study is to examine the correlation between playability, empathy ability, and play support competency of early childhood teachers, and the effect of playability and empathy ability of early childhood teachers on play support competency. For this study, a questionnaire was conducted for infants and toddlers in daycare centers and kindergartens nationwide, and data of 348 people were collected. For the results of the study, correlation
 analysis and multiple regression analysis were conducted using the SPSS 28.0 statistical program. The results of this study are as follows. First, for the level of playability, empathy, and play support competency of early childhood teachers, the level of playability was high, and the level of empathy and play support competency of early childhood teachers was also high. Second, there was a significant positive correlation between the play performance and play support competency of early childhood teachers, and a significant positive correlation between the empathy and play support competency of early childhood teachers. Third, the effect of play and empathy of early childhood teachers on play support competency was found to have a significant positive effect. These findings demonstrate that early childhood teachers' ability to support play is an important factor in childcare sites that are implementing play-based curriculum, and various studies that can be used in childcare sites should be activated to improve the playability and empathy of early childhood teachers.

Diagnosis of indoor air contaminants in a daycare center using a long-term monitoring

Recently, indoor air quality control is becoming important in Korea due to social concerns about health effects. Contaminants in the air can deteriorate indoor air quality and negatively affect the health of infants and toddlers in daycare centers. Also, with the COVID-19 spread, the outbreak of infectious diseases in daycare centers is another airborne threat to young children. In closed spaces, air contaminants such as PM10 can be used as potential containers to transmit indoor infectious matters. Since young children have immature immunity, indoor air contaminant controls are significant to support a healthy indoor air environment. Accordingly, the government of Korea has enhanced indoor air quality control regulations and recommendations, but on-site evaluation of daycare centers is still not sufficient to provide systematic knowledge of the indoor air contaminants. Therefore, this study monitored a daycare center in the metropolitan area and then diagnosed the occurrence and correlations of indoor air contaminants. The results of this study verified that many hours still exceeded the maximum air quality criteria in the daycare center, which were mostly found during the daytime. Also, correlations between indoor air contaminants were varying depending on outdoor air conditions. The findings of this study are expected to be used to improve a healthy indoor environment and ensure air safety in daycare centers.

Day care room transitions for toddlers: Recommendations for a supportive physical environment

The physical setting can be used to facilitate room transitions for toddlers in day care centers. A case study approach is taken to provide specific examples of supportive physical features for toddler transitions. Recommendations that support the transition process are provided.

Outbreaks of astrovirus gastroenteritis in day care centers

This study evaluated astrovirus as a cause of diarrhea outbreaks among infants and toddlers in day care centers. Stool specimens were collected weekly during four periods (from January 1986 through December 1991) from children 6 to 30 months of age who were enrolled in prospective studies of diarrhea in day care centers. All diarrheal stool specimens were tested for bacterial enteropathogens, rotavirus, enteric adenovirus, and Giardia lamblia. A total of 1365 stool specimens from 70 outbreaks in which no etiologic agent was identified and from another 11 outbreaks with a known cause were tested for astrovirus, by means of a monoclonal antibody-based enzyme immunoassay. Confirmatory testing was performed by reverse transcriptase-polymerase chain reaction with primers designed to produce an 89 base-pair product. Astrovirus was detected in 6 (7%) of the 81 outbreaks. Of 217 children tested, 73 (34%) were infected with astrovirus; infections in 35 (48%) were symptomatic and in 38 (52%) asymptomatic. The six outbreaks lasted 11 to 44 days (median 22 days). Astrovirus excretion was detected for a duration of 2 to 30 days, with excretion occurring from 1 to 8 days (median 2 days) before diarrhea began to 1 to 20 days (median 2 days) after diarrhea ceased. Younger children (< or = 12 months) were at greater risk than older children (p = 0.011) of becoming infected with astrovirus during an outbreak and were more likely (p = 0.015) to have symptoms when infected. Of 24 specimens with astrovirus by enzyme immunoassay, 20 (83%) were confirmed to have the virus by reverse transcriptase-polymerase chain reaction. Astrovirus was an important cause of outbreaks of diarrhea among children attending day care centers, more frequently infected younger children, and often produced asymptomatic infections.

Detection of rotaviruses in the day care environment by reverse transcriptase polymerase chain reaction.

Group A rotavirus is an important cause of morbidity among infants and toddlers in day care centers. Transmission by the fecal-oral route is well established, but fomites and environmental surfaces may also play an important role in transmission. A highly sensitive polymerase chain reaction (PCR) assay was used to detect rotavirus RNA in day care environments. Areas sampled included floors, diaper change areas, toy balls, and other surfaces. In two centers undergoing outbreaks of rotavirus, 7 (39%) of 18 toy balls had detectable rotavirus as did 8 (21%) of 39 swabs from environmental surfaces. By comparison, only 1 (5%) of 21 toy balls and 1 (2%) of 44 environmental surface swabs had detectable rotavirus in centers without rotavirus outbreaks (P = .0001). Thus, rotaviruses are highly prevalent in day care centers during outbreaks of diarrhea. The monitoring of environments by sensitive nucleic acid amplification techniques may lead to strategies for the diminution of disease transmission within the day care environment.

Outbreaks of human enteric adenovirus types 40 and 41 in Houston day care centers

Human enteric adenovirus (EAd) types 40 and 41 cause diarrhea in young children, but little is known about their association with outbreaks of diarrhea in the child care setting. This study evaluated EAd as a cause of outbreaks of diarrhea among infants and toddlers in day care centers. Stool specimens were collected weekly regardless of symptoms during four periods from January 1986 to April 1991, from children 6 to 24 months of age enrolled in prospective studies of diarrhea in day care centers. All diarrhea stool specimens were tested for bacterial enteropathogens, rotavirus, and Giardia lamblia. A total of 131 outbreaks occurred during the study. No etiologic agent was identified in 77 outbreaks. Stool specimens from 75 of these 77 outbreaks and from another 21 outbreaks of diarrhea with a known cause were evaluated for EAd with a monoclonal antibody-based enzyme immunoassay. A total of 4402 stool specimens from 613 children from these 96 outbreaks was tested for EAd. The virus was detected in specimens collected during 10 outbreaks, 3 of which occurred in 1986, 3 in 1988, 1 in 1989, 1 in 1990, and 2 in 1991. Of 249 children, 94 (38%) in these 10 EAd outbreaks were infected with EAd. In 51 children (54%) the infection was symptomatic and in 43 (46%) it was asymptomatic. Outbreaks lasted 7 to 44 days (mean 24.5 days). Duration of EAd excretion ranged from 1 to 14 days (mean 3.9 days), with excretion occurring from 7 days (mean 2.6) before diarrhea began to 11 days (mean 5.3 days) after diarrhea stopped. Enteric adenovirus types 40 and 41 are an important cause of outbreaks of diarrhea among children attending day care centers, often involve children in more than one room, and frequently produce asymptomatic infection.

Endemic Cryptosporidium and Giardia lamblia Infections in a Thai Orphanage

We conducted a point prevalence survey for enteric protozoa in 205 institutionalized orphans 1-61 months of age in Bangkok, Thailand. Cryptosporidium was identified in 17 children (8%), Giardia lamblia in 42 (20%), and 3 children (1%) had both parasites. At the time of diagnosis, diarrheal symptoms were present in a minority of subjects: 36% of children with Cryptosporidium alone, 10% with G. lamblia alone, and in 20% of those with neither parasite. Although chronic nutritional status (height/age) was similar in all groups, acute nutritional status (weight/height) was lower only in children with Cryptosporidium (Z score = -1.39 +/- 0.13) compared with children with G. lamblia (mean Z score +/- SEM = -0.56 +/- 0.26) or neither parasite (Z score = -0.78 +/- 0.13; P = 0.05). Detectable levels of Cryptosporidium-specific IgG antibodies by ELISA were identified in 15 of 16 Thai children with Cryptosporidium and in 17 of 19 Thai children without Cryptosporidium (mean OD +/- SEM = 1.27 +/- 0.18 vs. 1.06 +/- 0.13, respectively), but in only 1 of 18 sera from toddlers in day-care centers in Denver, CO (OD = 0.128 +/- 0.03). Although neither infection with Cryptosporidium nor G. lamblia was consistently associated with acute diarrheal symptoms, Cryptosporidium was more often associated with depressed acute nutritional status than G. lamblia. The high prevalence of specific antibodies to Cryptosporidium in Thai orphans suggests an association between high rates of exposure with asymptomatic excretion of the parasites.

Rotavirus in infant-toddler day care centers: Epidemiology relevant to disease control strategies

A 15-month prospective longitudinal study of diarrhea and rotavirus (RV) infection was conducted concurrently in infants and toddlers in day care centers (DCCs) and in a large pediatric clinic in Houston. The mean number of children in the DCCs was 223; the diarrhea rate during the first 12 months was 2.62 episodes per child-year. Rotavirus accounted for approximately 10% of the total episodes of diarrhea in the pediatric clinic and DCC populations, but 50% during the winter months. The occurrence of RV in the DCCs paralleled that seen in the pediatric clinic. The annual rate of RV infection in DCCs was 0.55 episodes per child-year, with diarrhea occurring in only 40% of the episodes (0.22 episodes per child-year). There were 45 diarrhea outbreaks in DCCs, for a mean of 3.8 per center per year; nine of these outbreaks were associated with RV. Polyacrylamide gel electrophoresis of RNA genome patterns of RV strains from eight of these outbreaks showed that in seven outbreaks a single strain was identified in children in that DCC, whereas multiple strains were identified simultaneously in the community. The age distributions of symptomatic and asymptomatic RV infections in DCC study children were not significantly different. In symptomatic RV-infected children in DCCs, 42% had RV identified in stool specimens within 2 days before diarrhea occurred. Thirty-eight DCC children had more than one episode of RV infection, but only five had two symptomatic RV infections. Diarrhea caused by RV is common in children in DCCs, often occurs in outbreaks due to the same strain, and parallels disease in the community; asymptomatic RV infection is also common in children in DCCs.

Same- and cross-sex friends: Implications for interaction and social skills

Sex cleavages in toddler peer groups were investigated in two studies. In the first study, playmate preferences and initiations and responses to friends were examined. Three types of initiations and their responses were examined during the free play of 46 toddlers in day care centers. A preference for same-sex playmates was strongest in the oldest girls. Boys tended to ignore or refuse girls' initiations when the initiations took the form of specific requests to play a game compared with a more general approach. Friendships tended to be made with members of the same sex. However, children having same- and opposite-sex friends were less likely to initiate and respond to friends on the basis of sex. Children with fewer same-sex preferences initiated more games. In the second study, cross-sex friendships in 329 early toddlers, late toddlers, and preschool children were examined. Some children in all age groups had cross-sex friends, but the number decreased with age. Children with cross-sex friends appeared more socially skilled than children without cross-sex friends.

Diarrheal illness among infants and toddlers in day care centers. I. Epidemiology and pathogens

We conducted a 2-year prospective study of diarrheal illness in children ages 0 to 36 months in 22 day care centers in Maricopa County, Arizona. In 7464 child-months of observation, 465 sporadic cases and 170 outbreak-associated cases of diarrhea were identified. Enteric pathogens were identified in 20% of diarrhea episodes. Giardia lamblia, rotavirus, and Campylobacter jejuni were the most common pathogens. Giardia was significantly more common in toddlers than in infants and was found in 19% of asymptomatic child contacts of symptomatic infected children. Rotavirus was significantly more common in infants than in toddlers. In outbreaks, shorter duration of child enrollment was associated with illness. Comparison of day care center characteristics revealed that only a lower score in standardized observations of hygiene and child-handling practices was associated with greater risk of diarrhea. Infectious diarrhea appears to be common in diaper-age children in day care centers, but the patterns of disease differ for different pathogens and for the infant and toddler age groups.

Diarrheal illness among infants and toddlers in day care centers. II. Comparison with day care homes and households

During the second year of a prospective study of diarrheal illness among 0- to 36-month-old children in day care centers in Maricopa County, Arizona, we concurrently studied children of the same age in 30 day care homes and 102 households not using day care. The seasonal pattern of diarrhea, frequency of pathogen isolation, and relative frequency of individual pathogens were similar in the three settings. Giardia lamblia and rotavirus were the most common enteropathogens. Asymptomatic infection was identified in 14% to 21% of infant-toddler contacts of pathogen-positive cases of diarrhea. We compared rates of diarrhea in the three settings using five serial biweekly family-based surveys during the period of highest diarrhea rates. The incidence in infants and toddlers in DCCs (42 cases per 100 child months) was significantly higher than in DCHs (23 cases per 100 child-months) and in households not using day care (27 cases per 100 child-months); the DCH rate did not differ significantly from that in households not using day care. Among household sample children who began using day care during the survey period, the incidence of diarrhea was significantly higher than in household sample children not using day care.
