  • The study of germination and seedling growth characteristics of Neem under different soil and environment conditions was undertaken. The seed germination started 8 days after sowing in commercial bed soil, whereas, delayed germination was observed in sandy-loam (15 days) and sandy (19 days) soil. The highest germination (73.33%) was observed in commercial bed soil in green house, whereas, the lowest germination was observed in sandy soil (16.67%) and sandy-loam soil (8.33%). The seeds in the open field (sandy soil) also showed poor (10%) germination. The mean number of germination seed/day (GD) and seed germination vigor rate (GV) both were highest in the commercial bed soil with 0.733% and 16.67% respectively in the green house, whereas sandy and sandy-loam soil in green house and open field (sandy soil) all showed much lower GD and GV values. The seedling characteristics of nursery revealed that the seedling grown in the growth chamber in commercial bed soil was significantly higher in all the parameters comparing to others grown in green house and open field. The growth was nearly 7 fold in the chamber compared to that of the green house nursery observed in three months old seedlings. Likewise, HPLC analysis revealed that the green house grown seedling contain higher quantity of pigments compare to the chamber grown seedlings. Among the soils used the commercial soil alone or in combination with sandy and sandy-loam soil in the ratio of 2:1:1 respectively with the temperature of $27{\pm}2^{\circ}C$ showed better for Neem nursery preparation.

  • The aim of this study was to estimate the benefit from repeated examinations in the diagnosis of enterobiasis in nursery school groups, and to test the effectiveness of individual-based risk predictions using different methods. A total of 604 children were examined using double, and 96 using triple, anal swab examinations. The questionnaires for parents, structured observations, and interviews with supervisors were used to identify factors of possible infection risk. In order to model the risk of enterobiasis at individual level, a similarity-based machine learning and prediction software Constud was compared with data mining methods in the Statistica 8 Data Miner software package. Prevalence according to a single examination was 22.5%; the increase as a result of double examinations was 8.2%. Single swabs resulted in an estimated prevalence of 20.1% among children examined 3 times; double swabs increased this by 10.1%, and triple swabs by 7.3%. Random forest classification, boosting classification trees, and Constud correctly predicted about 2/3 of the results of the second examination. Constud estimated a mean prevalence of 31.5% in groups. Constud was able to yield the highest overall fit of individual-based predictions while boosting classification tree and random forest models were more effective in recognizing Enterobius positive persons. As a rule, the actual prevalence of enterobiasis is higher than indicated by a single examination. We suggest using either the values of the mean increase in prevalence after double examinations compared to single examinations or group estimations deduced from individual-level modelled risk predictions.

  • This study compared the effects of open and directed teaching styles on creativity and mathematical achievement. The subjects were 32 three- and four-year-old children enrolled in the Home Economics Laboratory Nursery School at the University of Arkansas during the fall semester of 1987. In this study, the open teaching style was a child-oriented method of teaching with the help or guidance rather than the actual instruction of teacher, while the directed teaching style was a teacher-oriented method of teaching with actual instruction of the teacher. Forty-eight activities and materials relevant to mathematical concepts appropriately designed for the subjects were used. The nursery school children were divided into morning and afternoon groups. Utilizing a Latin square design, the children in the morning group were taught by the directed teaching style for four weeks followed by a three week period of no planned mathematical activities, then taught by the open teaching style for four weeks. The children in the afternoon group followed the same schedule except the open teaching style was first. At the end of the two four-week sessions of mathematics experiences Thinking Creatively in Action and Movement and selected items of Tests of Basic Experiences 2: Mathematics were administered. The scores of each of the two tests were analyzed using a t-test of dependent measures for the two teaching styles, the sex, and the age of the children. Children taught using the directed teaching style showed a significantly higher originality and mathematical achievement scores than those taught using the open teaching style. Differences for sex and age revealed that the directed teaching style was a significantly better method of instruction to foster the originality for boys and the mathematical achievement for four-year-old children.

  • This study was conducted to evaluate the microbiological hazard on nursery school children's hands and to investigate the reduction effect of hand washing education. A total of 59 nursery school children's hands were tested. The average number of total aerobic bacteria was $3.72{\pm}0.38log\;CFU/hand$. Five children's hands(2 male and 3 female) were positive(14.3%) for the coliform bacteria. These results showed that hand washing education are required repetitively. Among the pathogenic bacteria tested in this study, $Staphylococcus$ aureus and $Bacillus$ $cereus$ were detected in 9(25.7%) and 16(45.7%) out of 35 their hands, respectively. Twelve out of sixteen $B.$ $cereus$ isolates(70.0%) produced enterotoxin. The results indicate that the hand hygiene of nursery school children needs to be improved. Comparing before and after hand washing in educated and non-educated group, the reduction effect of total aerobic bacteria on their hands was 0.42 and 0.60 log CFU/hand, respectively. The educated group showed 0.18 log CFU/hand higher reduction effect than non-educated group but microorganism did not eliminate perfectly. From the results, using a hand sanitizer after washing with soap and the continuous hand washing education are required to control the contaminated bacteria on nursery school children's hands.

  • It is essential that the evaluation of official development assistance (ODA) projects is conducted based on empirical research for the performance and improvement of the project. This study intended to quantitatively figure out the actual status and performance of ODA projects. The performance of the Rumpin Seed Source and Nursery Center project implemented by the KOICA was evaluated in items of relevance, efficiency, effectiveness, impact, sustainability, which are OECD Development Assistance Committee(DAC) evaluation criteria. From August 26, 2019 to August 29, 2019, a survey was conducted on 50 visitors and 54 stakeholders of the Rumpin Seed Source and Nursery Center. Through on-site survey, problems in the donation project and operation in Indonesia were identified and measures for improvement was grasped. As a result of the study, the value scored by OECD DAC evaluation criteria of the Rumpin Seed Source and Nursery Center project based on the Economic Development Cooperation Fund(EDCF) evaluation grade was evaluated as a very successful class in all items. The average score of the recognition question was 4.08 points for visitors and 4.08 points for stakeholders, and the average score for the satisfaction question was 4.37 points for visitors and 4.11 points for stakeholders, which were high overall in both groups. The main factor that affects the project awareness of the visitors was the fact that the Rumpin Seed Source and Nursery Center was created based on Korean technology, and it was confirmed that Indonesia's own items related to similar projects had a great influence on the project satisfaction. In the case of stakeholders, project support in Korea affected their recognition, and it was found that relevance, efficiency, effectiveness items had the greatest impact on the level of project satisfaction of stakeholders derived from the DAC individual evaluation results. Efforts are required to increase the main factors by reflecting the results of each item and to preserve and maintain the project. This study is significant in determining the performance of the ODA project based on empirical data, and it is believed that it can be used as basic data for supplementing and strengthening the project in the future.

  • To investigate the possibility of developing the seeding measure for river bank slope revegetation, germination experiment and early growth observation were conducted using 3 native species growing naturally around river banks such as Pennisetum alopecuroides, Phragmites communis, and Miscanthus sinensis. The applied seeding methods were 3 such as scattering seeds, tillage after scattering seeds, and covering up seed with soil after scattering seeds. According to seeding methods, germination experiment and early growth observation were carried out on nursery bed soil in greenhouse. As results of this study, all the 3 native plant species' germination ratio and growth in length on nursery bed soil were highest on the seeding method of covering up seed with soil. Also it was verified by Duncan's multiple range test that the germination ratio and growth in length on the seeding method of covering up seed with soil is distinguished from those on other two seeding methods. According to this results, the best possible seeding measure to be developed should be mechanical seed spraying with soil.

  • The purpose of this study was to investigate the moderational effects of self-efficacy on the relationship between job satisfaction and turnover intention of nursery teachers. Data were collected from 355 nursery teachers on JSS, TIS, and SES, which then were analyzed using correlation and multiple regression. The major findings of this study were as follows: First, job satisfaction was positively related to self-efficacy, Second, job satisfaction was negatively related to turnover intention. Third, self-efficacy was negatively related to turnover intention. Fourth, self-efficacy had moderational effects on the relationships between job satisfaction and turnover intention. The above findings imply that various programs should be taken to enhance the self-efficacy of teachers in order to reduce turnover rates.

  • This study reviews recent changes in parenting support policy in Japan, and examines the roles and functions of day-nursery as the base for parenting support in the local community. The purpose of this study is to provide implications for the direction of the parenting support policy and child-care facilities for the local communities in South Korea. The analysis concentrates on the official national reports such as the Declining Birthrate White Paper and Japan's National Guidelines for Care and Education at Day Nursery by the Japanese Cabinet Office. The study finds that the Japanese government has introduced comprehensive medium and long-term policies for all the members of the community with recognizing the changes in the domestic and foreign child-rearing environments and social needs. These policies have also helped to improve the social awareness of parenting. The role of the day-care center has been raised as a significant part of the support for child-rearing in the local community due to the revision of the Child Welfare Act for nursery school teachers in 2001 and the official announcement of Japan's National Guidelines for Care and Education at Day Nursery in 2008. The study also concludes that the social responsibility of the nursery center has been strengthened by being utilized as a public resource for the community. From the findings, we can elicit the conclusions and implications that the roles and functions of child care centers as a significant base for parenting support in the local communities need to be considered. We also listen to the voices of stakeholders such as parents and staff of child care centers. Last but not least, we would understand the social role and importance of bringing up children by cooperation of the community members, and promote the role of child care centers as a central place providing and communicating information on child-rearing in the local communities.
