  • In the modern pig production, pigs are weaned at early age with immature intestine. Dietary and environmental factors challenge the intestine, specifically the jejunum, causing inflammation and oxidative stress followed by destruction of epithelial barrier and villus structures in the jejunum. Crypt cell proliferation increases to repair damages in the jejunum. Challenges to maintain the intestinal health have been shown to be related to changes in the profile of mucosa-associated microbiota in the jejunum of nursery pigs. All these processes can be quantified as biomarkers to determine status of intestinal health related to growth potential of nursery pigs. Nursery pigs with impaired intestinal health show reduced ability of nutrient digestion and thus reduced growth. A tremendous amount of research effort has been made to determine nutritional strategies to maintain or improve intestinal health and microbiota in nursery pigs. A large number of feed additives have been evaluated for their effectiveness on improving intestinal health and balancing intestinal microbiota in nursery pigs. Selected prebiotics, probiotics, postbiotics, and other bioactive compounds can be used in feeds to handle issues with intestinal health. Selection of these feed additives should aim modulating biomarkers indicating intestinal health. This review aims to define intestinal health and introduce examples of nutritional approaches to handle intestinal health in nursery pigs.

  • The importance of nursery facilities and the demand for the facilities have increased consistently due to the spread of 'universal social welfare' idea. However, the supply of the facilities is appraised insufficient. Therefore, this study aims at analyzing the spatial suitability of supply and demand of nursery facilities in Seoul. In this respect, this study surveyed all nursery facilities in Seoul, using 2011 Child-care Statistics published by the Ministry of Health and Welfare in 2012. In the analysis, this study performed GIS network analysis and regression analysis. What to follow is the findings of this study. First, the number of nursery facilities is positively correlated with the number of children and people per household, but is negatively correlated with the household income. Second, the present capacity of the facilities satisfies only 87.42% of the estimated demand. Third, this study performed GIS network analysis to find out the areas with excess or deficiency. As a result, the nursery service appears to cover 95.34% of the residential area in Seoul. However, the downtown area is served not enough. Finally, this study analyzed distribution characteristics of the nursery facilities in the aspect of equity, effectiveness, and efficiency. Most districts of Seoul meet the effectiveness criteria, but only a few districts satisfy the efficiency criteria. Thus, the efficiency of the facilities supply needs to be taken into account in managing policies.

  • This study was conducted to find out the optimum composition of nursery soil for raising seedling of ginseng (Panax ginseng C. A. Meyer). Total 9 kinds of raw materials were used such as peat-moss, perlite, leaf mould, rice bran, gull's guano, castor-oil plant bark, palm bark, cow manure and chicken manure for optimum composition of nursery soil in ginseng. Occurrence of damping-off in ginseng was lowered about 50% in nursery soil type 1, 2 and 4 than in other types nursery soil in June, and occurrence rate of rusty root also lowest in nursery soil type 1. As the salinity of nursery soil increased, so did the occurrence of physiological disorder in ginseng seedling. The cause of salinity increasing in nursery soil has closely relation to $NO_3-N$, $P_2O_5$ and $Na^+$ content. Plant height, root length, diameter and weight were longer and heavier in nursery soil type 1 (mixing ratio of peat-moss, perlite and leaf mould was 50 : 20 : 30 based in volume) than in other types of nursery soil. So nursery soil type 1 was selected for raising seedling of ginseng. pH and electric conductivity (EC) of selected nursery soil type 1 was 5.55 and 0.13 dS/m. Contents of $NO_3-N$ and $P_2O_5$ were 21.0 and 40.0 mg/L, and $K^+$ 0.36, $Ca^{2+}$ 3.38, $Mg^{2+}$ 2.01 and $Na^+$ $0.09cmol^+/L$, respectively.

  • High-quality protein ingredients have been used in nursery diets, in spite of expensive ingredients, to minimize nutritional deficiency and disease problems. Recent dramatic increases in prices of protein products for nursery diets have exacerbated the challenge. Spray-dried egg may be a part of the solutions. Therefore, this review describes the value of spray-dried egg in nursery diets as a high-quality protein source. Spray-dried egg is egg by-product and is produced by only eggs without shell that are below the USDA Grade B standards. Spray-dried egg is an excellent nutrient source: 1) highly digestible, 2) excellent balance of amino acids, 3) rich content of fat, and 4) high metabolizable energy. These can be attributed to growth of nursery pigs. Beyond the provision of bioavailable nutrients, spray-dried egg also may provide specific physiological benefits. Spray-dried egg contains 1) immunoglobulin antibodies (IgY: IgG in egg yolk) that may attach to intestinal pathogens and excrete them and 2) lysozymes antimicrobial protein that can damage bacteria cell wall. Thereby feeding spray-dried egg may reduce concentration of intestinal pathogen and thus improve potential gut health or enteric disease resistance in nursery pigs. This is important for physiologically immature weaned pigs. Based on these benefits, spray-dried egg is believed to have the same benefits as spray-dried plasma protein and milk products in diets for nursery pigs. Therefore, it is suggested that spray-dried egg has a great potential as a valuable protein source in nursery diets.

  • This study was done to come up with a solution to effectively increase nutrition knowledge and education among nursery school teachers in the Gwang-ju metropolitan city area. The scores of teacher's nutrition knowledge were around the average of 9.4 points on a 15-point scale, which is about 63.1 points on a 100-point scale. When the types of subjects were compared, we recognized that the nursery school teachers with a college degree or those who have any training/education in nutrition had the highest scores in nutrition knowledge. Also, the nursery schools who have more than 101 children or public nursery schools had the highest scores in nutrition knowledge (p < 0.05). We can conclude that the knowledge of nutrition of nursery teachers is very lacking and it is not as high as it should be. In addition, we can also see that the dietary guidance and nutrition education time spent towards the children was very short. The lack of professional knowledge and education seems to be due to shortage of educational materials and because the teachers themselves lack the knowledge to pass on to their predecessors. In fact, even the teachers themselves feel the need to set up more nutrition-related education programs, obtain more guides and materials to teach them, as well as implement more organized and systemized teaching methods.

  • This study aimed to provide the basic data to effectively teach nursery practices by investigating the dilemmas experienced by nursery school teachers-in-training majoring in children's welfare during nursery practicums and factors for solving such dilemmas. To this end, a qualitative analysis was conducted using journals, daily monitoring reports and interviews with 15 nursery school teachers-in-training in the Department of Social Welfare at S Women's University. The meaning related to the theme of the research was identified by repetitive reading in the process and then, the key words were determined through the categorization process. Next, the key words with similar concepts were re-classified and the sub-theme and the main theme were selected. In accordance with the analysis, it was identified that the dilemmas experienced during nursery practicums were related to tutors, children, classes, excessive work and the self. Furthermore, the subjects reported inner conflict because they had the alternative to select nursery or social welfare. The factors relieving such dilemmas included a change of children, encouragement from colleagues and the acquisition of practical knowledge. On the basis of the analysis results, this study proposed an approach to effectively implement nursery practicums for nursery school teachers-in-training majoring in children's welfare in the discussion chapter.

  • To recommend adequate covering materials and shapes of rice nursery bed for mechanical transplanting rice seedling, measuring of microclimate inside the rice nursery protected by polyethylene tunnel type, polyester tunnel type, and polyester flat type was compared to that outside the nursery. The vapor pressure deficit inside the polyester tunnel and polyethylene tunnel was higher than that outside the tunnel during daytime on a sunny day. During daytime on cloudy with rain day, the vapor pressure deficit inside polyester tunnel was higher than that in polyethylene tunnel or outside the nursery tunnel. The heat fluxes in the rice nursery tunnel during daytime flowed more to the soil than to the outside tunnel. Amounts of soil heat fluxes in polyethylene tunnel were higher than in polyester flat and polyester tunnel. The vertical profile of air temperature inside the nursery tunnel came to inversion during daytime and was lapse during nighttime regardless weather condition. The maximum temperature inside the nursery tunnel were 47.2$^{\circ}C$ in polyethylene tunnel and 37.$0^{\circ}C$ in polyester tunnel which was 21.1$^{\circ}C$ and 10.9$^{\circ}C$ higher than outside the tunnels respectively on sunny day. On cloudy with rain day, the temperature inside nursery tunnel was higher 8.4$^{\circ}C$ and 4.$0^{\circ}C$ polyethylene and polyester tunnel respectively then outside. Daily temperature changes became larger in the polyethylene tunnel, polyester tunnel, and outside the nursery tunnel in order. The rice seedling growth in polyester tunnel was better than the other nursery beds.

  • This experiment was conducted to determine the effect of nursery soils and seeding density on seedling growth characteristics in automatic facility for raising of rice seedlings. The seedling characteristics were evaluated for the 10-day and 15-day old seedlings grown in six different nursery soils including farm-made soils. Two levels of seeding amount, 250 g and 300 g/tray ($60{\times}30{\times}2.5$ cm), were applied to compare the seedling characteristics according to seeding density on different nursery soils. There were wide difference in soil components among the nursery soils tested. In acidity of nursery soils, 'Bunoog 2' was the highest, pH 5.1, and 'Samkyung' was the lowest, pH 8.6. The content of available phosphate was the highest value, 843 ppm, in 'Bunong 1' and the lowest (74 ppm) in farm-made soils. The total nitrogen content of 'Bunong 1, 2, 3' and 'Weonjo' soils was higher than there of 'Samkyung' and farm-made soils. There was no difference in plant height among three types of 'Bunong' soils (Bunong 1, 2, 3), but the seedling height grown in farm-made soils was shorter than there in other nursery soils. The plant heigh was slightly taller as the increase of seeding amount from 250 g to 300 g/tray, and the difference in plant height was larger in 15-day old seedlings as compared with 10-day old seedlings. Dry weight of seedlings grown for 15 days in three 'Bunong' soils was heavier than those in other nursery soils. Based on the growing characteristics of seedlings grown in different nursery soils, the heat result was obtained from a nursery soil, 'Bunoog 2', among six marketing nursery soils tested.
