A guideline published in 2018 by the Ministry of Health, Labour and Welfare stipulated confirmation of the vaccine history of nursery staff members.
This study was conducted to elucidate nursery ...teachers' vaccine and infection histories for measles, mumps, rubella, and varicella through survey responses.
After sending questionnaires through the mail to 5000 nursery teachers in November 2022, we received responses through December 2022. We measured the proportion of susceptibility in three ways. Additionally, we compared the proportions of susceptibility by disease by age class.
After receiving 1620 responses in all, the data of 1229 respondents under 50 years old were analyzed. Under the broad definition by which “no answer” was also regarded as unvaccinated or uinfected as well as “unknown,” the proportions of susceptibility for measles, rubella, and varicella were higher: 22–23%. For mumps, the proportion was 42%. For varicella, they were 31% for respondents in their 30 s, and 14% for respondents in their 40 s. For mumps, the respective values were 58% and 26%.
Respondents assessed for this study were less susceptible and unknown in comparison with earlier studies investigating health care workers, school teachers, university students, and pregnant women.
The survey revealed that measles and rubella susceptibility was higher among respondents in their 30 s. However, it was higher for varicella and mumps among respondents in their 20 s.
In nursery schools, influenza outbreaks have occurred every year. However, influenza characteristics of its diffusion among nursery schools, within each nursery school, and among classes of different ...ages in nursery schools remains unclear. This paper presents an examination of these matters using the Nursery School Absenteeism Surveillance System (NSASSy). All nursery schools in ward A in Tokyo introduced to the NSASSy in 2015. The study period was November 2015 through March 2016. The data of influenza patients were extracted from NSASSy. We examined four definitions of ‘starting date of community outbreak’ (SDCO) of influenza: 1) the first recorded day of influenza patients (SDCO1), 2) the last day of influenza patients recorded for two consecutive days (SDCO2), 3) three consecutive days (SDCO3), and 4) four consecutive days (SDCO4). We evaluated those four definitions by duration of the initial case at each nursery school from SDCO and evaluated the proportion of nursery schools at which the initial case occurred before SDCO. The average durations of initial cases at respective nursery schools from SDCO1–4 were 40.3, 26.3, 23.1 and 13.3 days. The respective proportions of nursery schools at which the initial case occurred before SDCO1–4 were 3.1%, 6.4%, 9.4% and 40.6%. Results demonstrate that SDCO3 is an appropriate definition of SDCO. Robustness checks for other areas, seasons, and population size constitute the next challenge for research in this area.
Representational momentum (RM) is a well-known phenomenon that occurs when a moving object vanishes suddenly and the memory of its final or vanishing position is displaced forward in the direction of ...its motion. Many studies have shown evidence of various perceptual and cognitive characteristics of RM in various daily aspects, sports, development, and aging. Here we examined the longitudinal developmental changes in the displacement magnitudes of RM among younger (5-year-old) and older (6-year-old) nursery school children for pointing and judging tasks. In our experiments, the children were asked to point at by their finger (pointing task) and judge the spatial location (judging task) of the vanishing point of a moving stimulus. Our results showed that the mean magnitudes of RM significantly decreased from 5- to 6-year-old children for the pointing and judging tasks, although the mean magnitude of RM was significantly greater in the 5-year-old children for the pointing task but not for the judging task. We further examined the developmental changes in RM for a wide range of ages based on data from the present study (5-year-old children) and our previous study (7- and 11-year-old children and 22-year-old adults). This
ad hoc
examination showed that the magnitude of RM was significantly greater in 5-year-old children than in adults for the pointing and judging tasks. Our findings suggest that the magnitude of RM was significantly greater in young children than in adults and significantly decreased in young children through adults for the pointing and judging tasks.
We carried out a survey, using a questionnaire, on the approaches being taken by nursery schools to infants' finger-feeding and on nursery school teachers' perspective on the importance of ...finger-feeding and related factors, in order to obtain basic materials which would assist in the promotion of infants' finger-feeding at nursery schools. The survey targeted nursery school teachers working at 1,627 nursery schools in Tokyo and the response rate was 37.1％. Approximately 95％ of the responding nursery schools are actively promoting finger-feeding. Nursery schools taking proactive approaches are encouraging cooperation among nursery school staff and are also actively providing assistance to infants' families. Many of the nursery school teachers report that infants active in finger-feeding later become highly-motivated towards eating. The survey suggests that factors relating to finger-feeding include infants' interest in eating, how they are fed at home, forms of meals and infants' individual likes and dislikes. From the above, we are of the opinion that in order to promote infants' finger-feeding at nursery schools it is critical that cooperation among nursery school staff be encouraged, that infants' interest in eating be fostered, and that cooking staff-including nationally-certified and other nutritionists-provide meals in forms which facilitate finger-feeding. Furthermore, we believe it is necessary for nursery schools to communicate the importance of finger-feeding to infants' families so that an environment at home can be developed where infants' finger-feeding is accelerated.
ABSTRACT This paper describes the metaphorical approach and how it relates to the development of mathematical thinking, to make improvements in the training of nursery educators. We present an ...experience with the Shao Yong square, which allows the integration of the metaphorical approach with the development of mathematical thinking, where we study the construction of the concept number with nursery school educators. The proposal highlights methodological strategies and provides as a framework for reading, discussing and pedagogical reflection. Information is provided for innovative classroom teachers of classroom fostering the understanding and teaching of mathematics. Keywords:
Individuals who visit hospitals with neurodevelopmental disorders have recently increased. To locate the cause for this increase, various factors, such as environmental and genetic ones, are being ...investigated. The objective of this study is to analyze the developmental delay in children and their background.
The participants were children who underwent the checkup for 18-month-old children in Togane city, Japan, from 2011 to 2021; 4,145 children—2,147 boys and 1,998 girls with a mean age of 18.8 months—were included. To examine the tendency over time and the background, we used the questionnaire about development and lifestyle reported by parents.
The number of children who did not produce pointing gestures or respond to their names and low-volume sounds tended to increase over the survey period (p = 0.0125, p = 0.0435, p = 0.0275). Next, we examined the relationship between pointing gestures and lifestyle and found that there was a relationship between attending a nursery school and bedtime and pointing gestures.
A slow developmental trend over the last decade has been observed among children. The background was related to attending a nursery school and bedtime, suggesting that interaction with others and sleep are important for the development of children.
In daycare centers, infants come in close contact with each other, and contact, droplet, and mouth-to-mouth infections may occur owing to sharing of toys. Additional effective disinfection methods ...should be considered aside from wiping with disinfectants—including alcohol or sodium hypochlorite solution—for environmental disinfection of daycare centers. We aimed to examine the usefulness of hypochlorous acid water atomization in the effective disinfection of the classroom environment and toys at a nursery school.
Environmental cultures of the nursery and toys were prepared to evaluate the species and bacterial load and to assess the contaminated areas. Staphylococcus aureus petri dishes were placed at high-frequency contact sites, and hypochlorous acid water was atomized to achieve a 0.03-ppm atmospheric chlorine concentration. After the atomization, the amount of S. aureus bacteria on the Petri dish and the changes in bacterial count isolated from the environment and toys were evaluated.
Hypochlorous acid water atomization was performed for 5 h to avoid condensation. After a 3-h atomization, ≥99.99% of S. aureus was eliminated on petri dishes; furthermore, a significant disinfection effect was observed on environmental bacteria at least 1 h after atomization. For rubber and textile toys, the significant disinfection effect was observed 1 h after atomization, and for plastic toys, the effect was observed 3 h after atomization.
Hypochlorous acid water atomization is a useful strategy to disinfect nursery school classrooms.
In this paper, we constructed the storage furniture with tatami with an area of about 7.2m2 for the reinforced concrete building and examined floor impact sound insulation performance. As a result, ...when the storage furniture with tatami was installed, the sound reduction was achieved from Lr-60 to Lr-50 when the car-tire was vibrated and from Lr-55 to Lr-45 when the rubber ball was vibrated, respectively. As described above, this report clarified the feasibility of installing storage furniture with tatami in a real building to prevent heavy-weight floor impact sound.
