The purpose of this study is to examine differences between nursery teachers and kindergarten teachers in their perception on key elements of effective interactions and enhanced teaching competence. The subject of the study were 143 early childhood teachers in the Y region of Gyeonggi-do. The collected data was processed through frequency and percentage. For difference test, ${\chi}^2$ tests were conducted. The results of this study can be summarized as follows. First, both nursery teachers and kindergarten teachers perceived that listening and playing were the most important factors in effective interactions between young children and teachers. However, nursery teachers perceived the interaction through skin-ship and complimenting to be more important whereas kindergarten teachers perceived questioning and complimenting as necessary. For the teaching criteria, nursery teachers put more weights on playing while kindergarten teachers focus more on explaining and coorperating. In addition, about evaluation methods, nursery teachers perceived self-evaluation as important, whereas kindergarten teachers perceived observation notes as important. Second, about the elements to strengthen teaching competence, nursery teachers perceived that observation records should be utilized for understanding interest or desire. They also believe that development analysis and teaching methods should be improved through systematical teaching plan and evaluation and that enhancement of teaching material and education are necessary. In contrast, kindergarten teachers perceived that observation records should be utilized for teaching plan and development analysis and teaching methods should be improved through participating in the meetings related to career and education. They believe that providing a prize money through supervising evaluation is necessary.

The purpose of this study was to examine the types of image that early childhood teachers have about nursery teachers in detail in an effort to provide some information on how to build an ideal image of a nursery teacher. Another goal was to determine the right directions for teacher education based on the subjective opinions of early childhood teachers, which has not been covered in earlier studies. The Q-methodology was utilized to determine the awareness of early childhood teachers about the types of the images of nursery teachers and each type's characteristics. A Q-population was constituted by 310 types of images based on the results of earlier studies about the images of nursery teachers, and 48 Q-samples were selected according to frequency. And then 20 nursery teachers and 20 kindergarten teachers were asked to classify the images of nursery teachers in nine stages by using the Q-sort, and the data were analyzed by the statistical package PASW 18.0. As a result, four different types of images appeared that the early childhood teachers had about nursery teachers, and the images were respectively named 'a practical-teaching-oriented type of teacher', 'a negative-system critical type of teacher', 'a positive-humanistic type of teacher' and 'a neutral-emotionally type of teacher'.

This study was carried out to investigate the effect of nursery period and block size on seedling quality and fruit yield of paprika (Capsicum annuum L. 'Cupra'). Seeds of paprika (Capsicum annuum L., Cupra) were sown in rockwool plugs. Seedlings were transferred and grown to the rockwool block different sizes: $5{\times}5$, $7.5{\times}7.5$ and $10{\times}10cm$ at sowing after 15 days. The plants were transplanted by 25, 30, 35, 40, 45 and 50 days we planted the seeds to the rockwool slabs. Seedling growth was not influenced by block size in the 25 day old plant, since then growed poorly with increasing nursery period in the $5{\times}5cm$ block size, plant height, stem diameter, fresh weight, dry weight have no difference from $10{\times}10cm$ and $7.5{\times}7.5cm$, but leaves and leaf area were higher $10{\times}10cm$ than the $7.5{\times}7.5cm$ block size. Growth of the paprika in field 80 days after sawing did not differ from nursery period and block size below 35 days old, but decreased with increasing nursery period and decreasing block size beyond 40 days old. Flowering did not differ from nursery period and block size below 35 days, but delayed with increasing nursery period and decreasing block size beyond 40 days old. The highest yield was obtained from 30 and 35 days old, and decreased with increasing nursery period and decreasing block size beyond 40 days old.

This study was conducted to determine the optimum intervals of shelves and seed-tray layout in container for raising rice seedlings at automatic facility. The seedling characteristics were evaluated with 10-day to 20-day old seedling grown under the different intervals of nursery shelves and seed-tray arrangement in the containers. The plant height was increased as the shelf intervals in nursery containers from 17 cm to 23 cm. The difference in plant height was larger in seedlings seeded at May 10 than those at June 10 and in 20-day old seedlings as compared with 10-day old seedlings. The growth characteristics of seedlings was significantly varied with the layout intervals of nursery tray on the containers. The seedling height was shorter as the extension of layout intervals of the tray on the shelf of nursery containers, but the seedling quality was increased in the seedling which grown on the trays arranged at 3 to 5 cm intervals. The light intensity was remarkably different from the position of nursery tray in the container. The illumination intensity was the highest on the uppermost tray. However the seedling height was shorter as the raising of tray position from the lowest shelf to the highest it in nursery container. The best results based on the seedling characteristics was obtained from the seedlings which grown in the tray arranged at 3 cm interval on the ten-shelf container with 20 cm intervals.

The present study was performed to investigate the effect of ozonation of the swine nursery building on indoor air quality and growth efficiency of the weanling piglets. Forty 21-day-old, cross-bred weanling piglets were housed in two ozonated or unozonated pens(10 males and 10 females per pen) for 3 wk alternately in a swine nursery building and this procedure was repeated three times. Ozone was generated using a commercial apparatus outside the nursery building and infused into the nursery building through a duct at a level of 0.03 ppm. Indoor concentrations of harmful gases were measured at 2-h intervals for a 24-h period per each 3-wk feeding trial. Indoor ammonia and carbon dioxide gas concentrations were reduced by the ozonation(P〈0.01) by 21% and 7%, respectively, compared with those of the control(unozonation), although hydrogen sulfide concentration was not affected by the treatment. However, the weight gain, feed intake and feed/gain of the piglets did not change due to the ozonation. Results suggest that ozonation of the swine nursery building is effective for improving the indoor air quality without affecting the production efficiency of weanling piglets.

Methods : This study was made from July to September in 2009 to nursery teacher by having the self-report questionnaire for teachers of infant nursery who are performing nursry school tearcher. Total 187 questionnaire were distributed and among these, 167 questionnaire excluding 20 questionnaire of incomplete responses were statistically analyzed with SPSS12.0. Results : The efficacy is highly in a married person(p=0.001) according to the teacher's age(P=0.006), perceived good oral status(p=0.001) according to the oral conditions and has the significant difference. The internal locus of control is highly in a married person(p=0.006) according to the teacher's age(P=0.037) and the marital status and has the significant difference statistically. The external locus of control is the highest(p=0.038) in the age of 40 among teacher's age and has the significant difference statistically. The oral disease management beliefs is the highest in the age of 20 ~ 29(p=0.001), highly in married(p=0.003) and has the significant difference according to the marital status and perceived good oral status(p=0.045) according to the oral conditions. There has no significant difference in the efficacy, the internal locus of control, the external Lotus of Control, oral disease management beliefs following by the infant oral care after taking medicines and oral care of infants after tooth brushing. Conclusions : Therefore, the oral health promotion activities should be induced by educating the nursery teacher and it needs to spread out the oral care education with the development to operate practically. It is considered in need of the infant oral care which is not burden on to the nursery teacher but helpful to the infant by connecting the subjects of dental hygiene and oral health education training.

Earthworm cast was investigated in this study in order to domestically develop inexpensive and safe plug nursery soil. 20,30,40 and 50% of earthworm cast were added to the nursery soil as vegetable plant growth media, in which peatmoss and vermiculite constituted the rest of the soil. The effects of earthworm cast on the growth of pepper (Capsicum annuum L.) seedling were obtained as follows. 1. According to the growth stages, significant differences(p=0.001) were recorded in number of leaves, leaf area and biological dry matter yield per plant(shoor or root dry matter yield per plant). In view of mixing ratios in the nursery soil, number of leaves, leaf area and stem weight per plant showed differences significantly at 1% level and leaf weight, root weight and biological dry weight per plant at 5% level, respectively. 2. The nursery soil with earthworm cast showed increased number of leaves and leaf area per plant compared to the commercial nursery soil particularly in the later stage of this study than in the earlier stage 3. Through the total period of seedling growth, leaf weight, stem weight and root weight per plant in the nursery soil with earthworm cast were genrally higher than those in the control and this trend was apparant in the treatment of more than 40% of mixing ratio with earthworm cast. 4. Although leaf weight per plant was higher than stem weight per plant till the 3rd week, from the 4th week stem weight per plant was getting higher. In the later stage of seedling growth, the stem weight was higher in the earthworm cast mixed treatment than that in the control. 5. There was no significant difference on biological dry matter yield in the earlier stage of this study, however in the later stage, it was higher in the earthworm cast mixed treatment than that in the control.

The objective was to evaluate in vitro prediction of ileal digestibility of protein and amino acids (AA) for current nursery pig diets (n = 10) by using pepsin and pancreatin incubations. To compare in vivo ileal digestibility, forty nursery pigs (4 pigs per diet) with an initial BW of $12.2{\pm}2.7$ kg were surgically equipped with T-cannula in the distal ileum. In all cases, the values of in vitro digestibility were higher than those of in vivo digestibility (p<0.05). With regard to the relationships of essential and non essential AA (CP), the $r^2$ value was 0.76. With regard to AA, high relationships were observed in Ile, Thr, and Gly (0.85, 0.83, and 0.89, respectively). Also, there was a lower relationship for Arg, Met, Ala, Asp, Glu, Pro, Ser, and Tyr with $R^2$ values of 0.56, 0.54, 0.40, 0.54, 0.45, 0.24, 0.49, and 0.35, respectively between in vitro and in vivo digestibility. The EAA relationship ($R^2$ = 0.71) was generally higher than that of NEAA ($R^2$ = 0.50) numerically. In conclusion, there were strong linear relationships between in vivo and in vitro ileal digestibility (CP, Ile, Thr, and Gly). In vitro prediction of ileal digestibility (CP, Ile, Thr, and Gly) seems to have significant potential for practical application.

A site survey in two apartment complexes and a nursery experiment were carried out in this study to provide basic data of the long-pending growth characteristics of major landscaping trees, such as Picea abies, Pinus parviflora, Metasequoia glyptostroboides, Magnolia denudata, Acer buergerianum and Acer palmatum. According to the main results, the survival rates were very low, reflected by the average survival rate of the four species was 95% at the nursery site. And, it was presumed that the site conditions of two apartment complexes for tree growth were very inferior to those of the nursery site, taking into consideration that the increment percents of growth factors of the tree species at the nursery site were relatively higher than those of the apartment complexes. The distribution patterns of the current growth factors of trees showed a normal distribution. The regression equation of breast diameter on diameter at root collar showed especially high predictability. And, it was thought that the most critical limiting environmental factors on tree growth at the apartment complexes were found to be alkaline pH caused by excessive Ca, high percent base saturation, insufficiency of available moisture content, bad drainage due to inferior soil texture, high soil hardness, lack of organic matter and shortage of cation exchange capacity in soil.
