This study was aimed at development of a nutrition education program, which was designed for children, their parents and personnel in preschool nursery facilities and carried out by dieticians. The program was conducted at 6 preschool nursery facilities for 3 months from July to September 1998. Four-hundred thirty-three children aged 2 to 7 years were engaged in the program. Children in each class were given nutrition education practice once a week by dieticians using education materials and a guide book based on a 12-week program. The themes of nutrition education for children consisted of 'knowledge of food sources and foods', 'relations between food and health', 'other roles of food', 'right eating habit', and 'cooking practice'. Each of five leaflets on nutrition education for parents was delivered eery three weeks in a series and leaflets were posted on a bulletin board. Nursery school teachers were educated by their participation in the class with dieticians using education materials. Evaluation of nutrition education by children, parents and personnel was carried out by interviewing and using questionnaires before and after the program. Children responded more positively more positively on their eating behavior and sanitary behaviors after nutrition education. Parents'opinions on the nutrition education program were positive : 72.3 described the nutrition education program as 'very good'and 'good'. In addition, 71.3% answered that the education materials for parents were helpful. A majority(93.8%) of personnel in facilities evaluated the nutrition education program effective. Nursery personnel evaluated the importance of general nutrition knowledge, childhood nutrition, and obesity control for nutrition management and nutrition education more highly after nutrition education. This study indicates that nutrition management and nutrition education programs for preschool nursery facilities are necessary and they would be effective when implemented by dieticians.

Purpose: This study aimed to identify correlations between the status of the umbilical cord and neonatal health status. Methods: In total, 172 newborns were enrolled who were admitted to the newborn nursery with a gestational age of 35 weeks or older and a body weight of 2 kg or above. Data were collected on the basic personal information of the newborns, the diameter and soft tissue status of the umbilical cord, and neonatal health status after birth. Analyses were performed using t-test, analysis of variance, χ² test, and Fisher exact test. Results: Umbilical cord diameter exhibited a statistically significant difference by sex (t=2.71, p=.007). A thin umbilical cord diameter was associated with a 1-minute Apgar score less than 8 points (t=2.47, p=.015) and with being transferred to the intensive care unit (t=2.45, p=.015). Poor soft tissue status of the umbilical cord was associated with a 1-minute Apgar score of less than 8 points (χ²=16.68, p<.001) and with oxygen being supplied (χ²=4.81, p=.028). Conclusion: Assessing the umbilical cord diameter and status in newborns is an important tool for evaluating neonatal health status after birth, and this point also underscores the importance of professionals' careful observations in the newborn nursery.

In comparison of physicochemical properties between expanded rice hulls (ERH) and a commercial nursery soil (Bunong), the pH and content of organic matters were higher in ERH than those of Bunong soil. However, the content of available phosphate, $\textrm{NH}_4\textrm{-N}$ and $\textrm{NO}_3\textrm{-N}$ were lower in ERH as compared with Bunong soil. The growth characteristics of seedlings were evaluated for 15-day old seedlings grown in five different nursery soils including ERH. The plant height was the tallest (22.8cm) in Bunong soil and shortest (12.8cm) in ERH. There was no difference in number of leaves among five types of nursery soils. The best results based on the seedling quality and root intensity was obtained from the seedlings grown in the nursery soil which ERH was used for bedding and Bunong soil for covering in the seed tray. The weight of a seed tray with Bunong soils was 27% heavier than that of 'ERH + Bunong soil'.

The purpose of this study is to make establishing criteria for Korea traditional nursery rhyme suitable for children and apply them effectively in early child education. The researchers of this study are firstly concerned with establishing criteria for Korean traditional nursery rhymes suitable for children. Secondly, they are concerned with establishing Korean traditional nursery rhymes suitable for children which are selected by following the established criteria. A Delphi survey was performed with early childhood educators and 30 related professionals to establish criteria for Korean traditional nursery rhymes suitable for children. The SPSS 12.0 program was used to calculate the standard deviation and average. Through this process the final seven criteria selected are: 'traditional play spaces and fun of play language is showed', 'lifestyles and emotions of children in the past is expressed', 'easy to understand story', 'the content is interesting', 'assisting in the development of children', 'easy to sing melody', and 'simple and repetitive in rhythm'. And 112 songs appropriate to the children were selected based on these criteria. The lyrics of the songs mainly expressed 'the joy of play.' it means songs need to combine with play to succeed to the next generation.

This study investigated the applicability of horticultural media with recycled coir substrates the growth of Chinese cabbage (Brassica campestris L. ssp. Pekinensis) and lettuce (Lactuca sativa L.) crop. The six different types of coir based substrates were A, Coir 45: Perlite 35: Vermiculite 12: Zeolite 8 (%), B, Coir 55: Perlite 25: Vermiculite 12: Zeolite 8 (%), C, Coir 65: Perlite 15: Vermiculite 12: Zeolite 8 (%), D, Coir 75: Perlite 5: Vermiculite 12: Zeolite 8 (%), E, Coir 85: Perlite 5: Vermiculite 5: Zeolite 5 (%) and F, nursery media (control). The pH and Electric conductivity of the horticultural nursery media were 6.06-7.00 and $0.45-1.10dS/m^{-1}$, respectively. The nursery media containing coir substrates had higher level of Total N, Ca, K, Mg and P than those without coir. Additionally, it was observed that the growth of Chinese cabbage was the best on D (containing 75% coir) while that of lettuce was the best on E (containing 85% coir). In general, when substrates containg a higher percentage of coir were used, the growth of Chinese cabbage and lettuce was ideal. Additionally, the P, Ca, and Mg content in both plants was not significantly altered by the amount of coir present in the media. However, with an increase in the amount of coir substrate, the chlorophyll, N, and K content was increased. After harvesting, there was no significant difference in the chemical properties of the horticultural nursery media of both plants. Thus, it can be suggested that, coir substrate after a single use could be recycled as horticulture nursery media.

Objective: This study was to evaluate standardized ileal digestibility (SID) of amino acids (AA) in fermented soybean meal (FSBM) for nursery pigs using both direct procedure and difference procedure when FSBM was added at 20% in diets. Methods: Forty-eight pigs at 9.2±0.9 kg body weight (BW) were individually housed and allotted to 4 treatments. Treatments included NFD (a semi-purified N free diet), FSD (a diet with 20% FSBM), CBD (corn basal diet), and CFD (corn basal diet:FSBM at 80:20). The FSD was used to measure AA digestibility in FSBM using the direct procedure, whereas CBD and CFD were used in the difference procedure. Pigs were fed for 10 days (0.09×BW^0.75 kg per day) and euthanized to collect ileal digesta for TiO₂ and AA. Results: Total endogenous AA loss was 12.1 g/kg of dry matter intake. The apparent ileal digestibility (AID) Thr was greater (p<0.05) and AID His (p = 0.073) and Leu (p = 0.052) tended to be greater using the direct procedure compared with the difference procedure. The SID Thr were greater (p<0.05) in FSBM for nursery pigs calculated using a direct procedure compared with a difference procedure. In addition, SID Lys in FSBM was about 83% to 88% for nursery pigs higher than SID Lys described in National Research Council (2012). Conclusion: The SID of AA in FSBM when included at practical levels using the direct procedure were similar to those from the difference procedure. Considering the SID of AA obtained using both direct and difference procedures, FSBM is an effective protein supplement providing highly digestible AA to nursery pigs. The SID of AA from this study was considerably higher than those previous reported. This study also indicates the importance of including the test feedstuffs at practical levels when evaluating digestibility.

This study was carried out to determine the optimum storage temperatures of six fruit nurseries ('Fuji' apple, 'Niitaka' pear, 'Sheridan' grape, 'Yumyoung' peach, 'Fuyu' persimmon, and 'Hayward' kiwifruit) from 1995 to 1997. Nursery plants were planted in field after storage at -5, 0, and $5^{\circ}C$ for one year. Nurseries stored at $0^{\circ}C$ showed highest survival rate and growth after planting. The survival rate of 'Sheridan' grape and 'Hayward' kiwifruit nursery plants stored at $-5^{\circ}C$ was 0%. Cold resistance of the two fruit nursery plants appeared weaker than others. Also, 'Niitaka' pear nursery plants stored at $5^{\circ}C$ showed significantly high survival rate and growth after planting. The higher storage temperature, the lower mineral and carbohydrate contents of nursery plants. Therefore, $0{\sim}5^{\circ}C$ in 'Niitaka' pear and near $0^{\circ}C$ in other five fruit nursery stocks were found to be the optimum storage temperatures.

soil survey and chemical analysis on mulberry nursery garden were carried out to study the causes of the non-sprouting phenomenon occured seriously in Buy and Ogchun in 1983 and Sangju in 1984. In addition, 115 nursery garden soils taken from 21 sapling produsers in Chungbuk province were analyzed in 1984. The results were as follows, 1. Symptom of dead saplings was the highest in boron deficiency by 59% and the lowest in rot symptom. The rest of saplings by 34.9% were not detected any symptom. 2. The nursery gardens showen non-sprouting phonomenon were located along the stream. As the result, soil depth was shallow, around 20cm deep and subsoil composed with coarse sand and gravels. 3. Nursery soils were mostly strong acid, low in Ca and Mg content, especially B, whereas available phosphorus and potassium were abundant at some gardens, and deficient at others. 4. Application of red earth or borax to nursery garden, especially to paddy, increased sprouting rate. 5. Paddy nursery garden occupied by 52.8% of 60.8ha of total garden area in Chungbuk province. Ninty point five percent of the nursery garden was lower in pH than 6.5, 87.0% lower in K than 0.5me/100g, 40.8% lower in Ca than 6.5me/100g, 94.8% lower in Mg the 2.00me/100g 99.1% lower in B than 0.3ppm.
