This study conducted a survey on 163 parents in Korea to investigate their interest in plants, experience in growing plants, and perception on horticultural activity programs (HAP) for their children. Most children (80.4%) of the respondents had experience participating in HAPs, and most of their experience occurred during school hours in preschool educational institutions more than once a month (60.3%). The more interest in plants and experience in growing plants the parents had, the more experience the preschoolers had in participating in HAPs, which implies that the experience of the parents with plants affected their children's participation in HAPs. Parents' most preferred location of HAPs was preschool educational institutions, and most preferred time was school hours with a frequency of more than once a week (57.1%), which is more frequent than the current status of HAPs in preschool educational institutions. Parents also responded that the most preferred instructors of HAP has are those with a professional background in horticulture. Among the activities in HAP for preschoolers, parents most preferred cooking (M = 4.05) activity, and they did not dislike any of the activities. They responded that the facilities for HAP needed to be improved to make HAP more active in preschool educational institutions. Overall, based on the current results, developing suitable HAPs and facilities for preschoolers, fostering professional HAP instructors, and educating parents about horticulture would enhance HAPs in preschool educational institutions, thus providing preschoolers with many benefits of HAPs.

As the population of preschooler increases with the increment of employed women today, the physical environment of day-care center is becoming an important factor for the preschooler as well as home environment. In order to create a suitable and desirable day-care environment for preschoolers, the using behavior of the preschoolers, who are the main users, needs to be applied to the spacial design. In this research, play preference area of Korea and United States which have different physical environments are analyzed. Child behavior observation analysis technique, interview with the teacher in charge, floor plan and furniture arrangement plan of the day-care centers and photography were performed for this research. The subjects were 63 preschoolers of 50 months old who are using Korean and American day-care centers and play of five minutes per preschooler was filmed for 3 days. Total 01 189 motion pictures were analyzed for this research. As a result, the physical environment, programs, preference area and finally the similarity and difference according to the gender were clarified for each countries' day-care center. The Korean preschoolers preferred the block area most, the second most favorite area being art for the younger class and language for older class. According to the gender, girls preferred language area while boys chose block area. On the other hand in American preschoolers' case, due to the large variety of play area, the play preference was distributed among various area except several high preference area. Based on this research, when designing indoor play area of day care centers, the area of block, language, and art which are popular play preferences should be considered firsthand, and gender preference is also needed to be thought of. These results may be used as an important data for planning the day care center play area in the future.

Objectives: The present study aimed to evaluate the usability, quality, and usefulness of the mobile application, CAMBRA-kids, for caries management in preschoolers. Methods: Ninety-one caregivers and preschoolers participated in the user evaluation of CAMBRA-kids. The evaluators assessed the usability, quality, and usefulness of CAMBRA-kids. The collected data were analyzed using R studio 1.2.1335 for Windows (RStudio Inc. 2018, Boston, MA, USA). The evaluations for usability, quality, and usefulness were analyzed with descriptive statistics, Kruskal-Wallis rank sum test, and Wilcoxon rank sum test. Results: On user evaluation, the quality and usefulness of the application scored >3 points, and majority of the users rated the quality and usefulness of the application as high. The quality of the application's system was the highest at 3.68 points, and the actual usage of the application was the lowest at 3.10 points. The application had the highest technological aspect score of 3.20, whereas the content related to oral health information had the lowest score of 3.10/5. Although the application showed no statistically significant differences in the quality and usefulness according to general characteristics, there was a statistically significant difference (p<0.05) between the two when compared between the caries risk group. For all items, the protector of the high-risk group evaluated the quality and usefulness of the application highly. The moderate risk group gave the lowest evaluation score for the application's quality and usefulness. The usability score of the application, according to the user version of the mobile application rating scale (uMARS), was 3.25, and the average engagement score was 2.82 (56.31%). The highest subscale score was 3.63. Conclusions: In this study, we found suitable quality, usability, and usefulness of the mobile application, CAMBRA-kids.

Word recognition test (WRT) for the children can be useful for diagnosing the degree of communication disability, prescribing hearing instruments, planning aural rehabilitation and speech therapy, and determination of site of lesions. The Korean standard monosyllabic word lists for preschoolers (KS-MWL-P) were developed considering the criteria given by the literatures. However, the authors of KS-MWL-P suggested more children should be included to verify homogeneity of the lists using psychometric function curve since only 8 children participated in the developing process. The purpose of this study was to explore the homogeneity of KS-MWL-P for supplementing the limitations of the lists employing psychometric analysis. To 23 preschoolers who have normal-hearing, 100 monosyllabic KS-MWL-P words were examined with the pictures. Psychometric function curve with linear slopes of 20% and 80%'s correct rates through accounting recognition scores of each monosyllabic word at variable intensities from -10 to 40 dBHL was obtained and analyzed. As a result, s-shaped psychometric function curve was presented with increasing correct rate depending on intensity and showed no statistical significant differences among each word and list. The congruous graph shapes among lists also indicated good homogeneity and the list 1,2,3,4's average slopes were 4.48, 3.86, 4.65, 4.50. It was verified that the homogeneity was suitable because the analysis of variance showed no statistical significance among lists (p>0.05). However, KS-MWL-P's order of slope according to the order of the number of items, $1{\sim}10$, $1{\sim}20$, $1{\sim}25$ showed no difference with the p-value of 0.93, 0.59, 0.91, 0.70 for the lists 1,2,3, and 4, respectively. Although KS-MWL-P was assumed that the lower-numbered items were easy for testing younger ages, this study's results could not agree with the author's conclusion. Considering this matter, rearranging of the number of items should be performed according to the analysis of slope suggested by this study for testing younger children with easier items. Other than this, in conclusion, KS-MWL-P was proved to be useful for clinical and rehabilitative evaluating and training tools for preschoolers.

Purpose: Screening of preschool-age children for nutrition programs to improve dietary intake and behaviors requires cost-effective and easily administered validated assessment tools. The purpose of this study was to develop a parent/caregiver-administered instrument for measuring diet quality and behaviors of preschoolers as a nutrition quotient for preschoolers (NQ-P). Methods: Development of NQ-P was carried out in three steps: item generation, item reduction, and validation. The 24-h dietary record was selected as the gold standard reference tool. The 38 items of the NQ-P checklist were derived from a systematic literature review, expert in-depth interviews, statistical analysis of the fifth Korean National Health and Nutrition Examination Survey data, and national nutrition policies and recommendations. Self-administered questionnaires were delivered to parents who recorded 24-h dietary intakes of 100 responders aged 3~5 yr. Pearson's correlation was used to measure the level of agreement between questionnaires. Item reduction was performed, and 20 items were selected based on survey results, expert reviews, and priorities of national nutrition policy and recommendations. The 412 nationwide subjects sampled through daycare centers completed the 20-item checklist questionnaire. The construct validity of the NQ-P was assessed using confirmatory factor analysis, LISREL. Results: After analyses of exploratory factors, NQ-P items identified three dimensions of diet (balance, moderation, and environment). The three-factor structure accounted for 49.28% of the total variance. Standardized path coefficients were used as weights of the items. The NQ-P and three-factor scores of the subjects were calculated by the obtained weights of the questionnaire items. Conclusion: A food behavior checklist for preschoolers' NQ would be a useful and suitable instrument for evaluating nutrition adequacy and dietary quality of Korean preschoolers.
