This study was conducted to identify landscaping elements such as location, situation and feng shui included in the spatiality of Jangseong Pilmaseowon and to interpret aesthetic features of visual-perceptual spatial composition according to its arrangement. As it is shown in 'Pilamseowon', 'Pilbongseowon', and 'Gimhaseoseowon' appearing in antique maps, the awareness considering 'Pilam' as 'Pilbong' and 'Gimhaseo' was revealed. Mountain Pilamsan[Mountain Munpilsan] which is the location of seowon and Pilam(Brush-shaped rock) is the core of establishment of location identity of Pilamseowon and the symbol of Haseo Kim In-hu, which shows that they are deeply related to Ingeoljiryeong(人傑地靈: 'a place derives reflected glory from an illustrious human') based on connection. Pilamseowon shows locational characteristics of living in stream(溪居) facing panoramic 'jeungsan field' without Ansan(案山). Based on the teachings of Neo-Confucianism, Village Maekdong which is the birth place of Haseo, Pilam, seowon geomancy considering the Danbonghamseo-type(丹鳳含書形) geographical shape, formative reflection, Pilmaseowon and structures revealed in building naming more clearly show symbolic landscaping features resulting from 'theory of 'Heaven-Man Unity'(天人合一)' representing the union of nature and haman, than other seowons. The maximization of centrality through connected yards constructed with the 'jeondang hujae(前堂後齋)' arrangement in the order of Whakyeon-lu, Chenogjeol-dang, Jindeak-jae or Sungui-jae, and Woodong-sa is a unique feature of spatial frame of Pilmaseowon. In addition, it reveals the centrality reinforced with 'the move of inner center through arrangement of Kyeongjang-kag and Kyesengbi inside 'YuSik(遊息)' space and religious space' and the landscaping arrangement of Pilmaseowon from installation and device for reinforcement of territoriality. Moreover, it was found that orders and aesthetic features based on Neo-Confucianism were logically realized in the formation of Pilmaseowon with visual and compositional landscaping arrangement such as 'reinforcement of view centrality through composition of windows and doors', 'securement of visual transparency through framing and duplication', and 'realization of hierarchy through height of jaesil toenmaru'. The meaning system and spatial or visual aesthetic features of Pilmaseowon newly arranged and interpreted through landscaping recomposition is not a coincidental but inevitable result. It is another resource basis and an element that can improve the internal exuberance of Pilamseowon. This landscaping reading study is expected to improve the understanding of landscapes of Pilmaseowon and elevate the sensibility of unrevealed cultural landscapes.

Purpose: This study was conducted to identify potential dangers involved in procedure and evaluate complications of percutaneous endoscopic gastrostomy (PEG) comparing to surgical gastrostomy (SG). Methods: A retrospective study of 66 children with feeding gastrostomy between 1994 and 2002 was done. Results: Of 66 children, 23 (mean age 29 months) had PEG and 43 (mean age 49 months) had SG. 31 cases of SG group had fundoplication for gastroesophageal reflux disease. PEG groups were followed up with an average 13 months and SG groups with 21 months. Major complications occurred in 33% of PEG group (8/23) and 55% of SG group (24/43). Major complications were significantly lower in PEG group than SG group and minor complications, too (p<0.05). Of major complications, aspiration pneumonia was the most common but paralytic ileus was significantly higher in SG group than PEG group. 8 patients died of underlying disease but not related to gastrostomy. Removals of stomata were done in 5 of PEG group and 3 of SG group. GER recurred in 25% of SG group with fundoplication and newly developed in 17% of SG group. GER persisted in 17% and newly developed in 5% of PEG group. Conclusion: The gastrostomy was a significant procedure with the potential to produce complications. PEG is recommended as an initial procedure in children requiring a feeding gastrostomy but should be considered a major undertaking.

Studies were carried out to elucidate the effect of temperature, glasshouse forcing date and $GA_3$ on the growth and flowering of pot Hydrangea macrophylla Ser. The plant height was elongated in the $5^{\circ}C$ treatments as 38 cm compared with $20^{\circ}C$ treatment as 6.7 cm, and stem length showed the similar results. The leaf length and width was broadened in the lower temperature, and stem diameter showed the same tendency. The first flowering date in the $15^{\circ}C$ and $20^{\circ}C$ treatment shortened markedly than $5^{\circ}C$ treatment. Days to flowering date of $5^{\circ}C$ was 161 day, while it shortened as 88 day in the $15^{\circ}C$ treatment. The flowering rate was 75.8~90.7% in the temperature. The plant height was elongated in the late glasshouse forcing date, and the leaf length and width showed the similar tendency. The plant height increased in the higher concentration of $GA_3$ compared to the control, and leaf length and width showed the similar results. The first flowering day was advanced by 7 days in the $GA_3$ $50mg{\cdot}L^{-1}$ treatment which had been transferred to greenhouse on Dec. 30 compared with the control of which first flowering day was March 17, and the days to first flowering was conspicuously shortened in the late glasshouse forcing treatment. The width of flower cluster was increased in the $GA_3$ at Dec. 30 glasshouse forcing treatment. The flowering rate was markedly decreased as 62.3% in the control of Nov. 15 treatment, but was increased as 97.9% of $GA_3$ $50mg{\cdot}L^{-1}$ of Jan. 15 treatment.

This study was conducted to obtain basal information for the development of perilla cultivars with improved quality. The F₇ population of recombinant inbred lines (RILs) from a cross between the parents of Daesil for seeds and Ipdeulkkae1 for vegetables was used as the material. We evaluated several agricultural characteristics and seed quality. Variations were observed in most of the measurements; for example, stem length (ranging from 66.0 to 150.0 cm), number of branches (from 5 to 23), flower cluster length (ranging from 5.1 to 10.5 cm), number of flower clusters (from 17 to 131), a-linolenic acid content (from 54.2 to 64.1%), and functional compound content (rosmarinic acid 869.5~3,508.1 ㎍/g; luteolin 47.4~864.3 ㎍/g; apigenin 57.1~296.7 ㎍/g) all showed variation. Significant correlations between stem length and the number of branches (0.561) and number of branches versus number of flower clusters (0.638) were detected in the RIL F₇ population. Most agricultural characteristics and seed qualities showed a normal distribution with large variation, and transgressive segregation was observed in many descendants with characteristics to those of their parents. Daesil/Ipdeulkkae1 RIL F₇ populations could be useful for future QTL analysis as well as for intermediate breeding lines for high-quality perilla cultivars.

Purpose: Preterm infants are very susceptible to malnutrition because of a lack of storage of nutrients, immature digestion and metabolism, and accompanying diseases associated with prematurity. The purpose of this study was to evaluate the effects of nutritional support by the pediatric nutritional support team (pNST) on the clinical course of preterm infants in the neonatal intensive care unit (NICU). Methods: Between July 2003 and July 2006, 48 preterm infants who were admitted to the NICU at Seoul National University Bundang Hospital were included. The subjects were divided into the following two subgroups according to the presence of NST activity; pre-NST group (n=23) and NST group (n=25). Hospital records were reviewed retrospectively. Results: Forty-eight preterm babies were included (M：F=27：21; gestational age, 25~33 weeks). A dietician, pharmacists, or the pNST participated in the prescription of total parenteral nutrition (TPN) more rapidly in the NST group (p=0.000). The fasting periods and TPN administration periods were significantly decreased in the NST group compared to the pre-NST group (p=0.017 & p=0.001, respectively). The doses of calories, protein, and lipids administered via TPN were significantly increased in the NST group compared to the pre-NST group (p=0.016, p=0.000, and p=0.000, respectively). The total period on antibiotic therapy was significantly decreased in the NST group compared to the pre-NST group (p=0.007). Conclusion: Because nutritional support by the pNST is of benefit to the clinical course of preterm infants in the NICU, the pNST should recommend to improve the nutritional status and clinical outcome of preterm infants.

This experiment was conducted to investigate the effects of planting density on the growth characteristics and root yield of Achyranthes japonica N. from 1995 to 1996. Stem diameter, no. of branch and fresh weight of above-ground parts per plant were reduced by increasing the planting density, but stem length, length and diameter of main root increased at high density, $25{\times}5cm$. The heighest percent of large roots was 71 % at $25{\times}5cm$ planting density. The dry root yield per 10a at $25{\times}5cm$ planting density was 7% higher than 306kg of $20{\times}5cm$ planting density, but root yields were lower in other planting density compared to $25{\times}5cm$ planting density. The root dry weight showed negative correlation with stem diameter, no. of branch and fresh weight of above-ground parts per plant but showed positive correlation with stem length, length and diameter of main root.

This experiment was carried out to investigate the effect of plant spacing on the growth and root yield at different harvesting year in Astragalus membranceus. A local variety collected in Jung Sun. Kang Won was used on the 30 and 40cm row spacing, with different spacing between plant of 5, 10, 15, 20cm respectively. Nitrogen, phosphorus and potassium fertilizers were applied as 6, 8 and 9kg/10a respectively, with compost of 1,000kg/10a. Branches, root length, root diameter and root weight were increased in the sparse planting compared with the dense planting. But emergence date, flowering date, stem height and node number were not significantly changed with plant spacing. The highest root yield was 211.8kg/10a at the $30{\time}10cm(67\;plants/m^2)$ in 1 year old plants of Astragalus membranceus. In case of two years old plants, branches, node number, root length, root diameter and root weight were increased in the sparse planting compared to the dense planting. But harvesting ratio was decreased in the dense planting, The highest dried root yield was 292kg/10a at the $40{\time}10cm\;(25\;Plants/m^2)$. In case of 3 years old plants, aerial part and root growth pattern were similar to the 2 years old plants, The dried root yield was highest(623kg/10a) in the $40{\time}10cm(25plants/m^2)$.

The experiments were carried out to develop simulation model for estimating the yield of soybean in upland and paddy field condition. Field experiments were done at National Institute of Crop Science in 2005. The evaluated soybean cultivars were Taekwangkong, Daewonkong, and Hwangkeumkong. Soybean seeds were planted by hill seeding with 3-4 seeds and row and hill spacing were $60{\times}10cm$ in upland and $60{\times}15cm$ in paddy field. Seeds were sown on row (without making ridge) and on the top of ridge in upland and paddy field, respectively. Field parameters were measured yield components ($plants/m^{2}$, pod no./plant, and 100-seed weight, seed yield and growth characteristics (stem length, leaf area at each stage, and dry weight of shoot) and after measuring they were compared the relationships with seed yield and yield components and seed yield and growth characteristics. Seed yield of soybean was affected by cultivars and planting density. Seed yield was higher in upland than paddy field due to the higher planting density in upland field. The upland soybeans generally had lower 100-seed weight than that of paddy field. Seed yield of soybean in a paddy field was greatest in Taekwangkong and followed by Daewonkong and Hwangkeumkong. The harvest index of taekwangkong and Hwanggumkong was higher in upland than paddy field, however, it was higher in paddy field than upland in Daewonkong. Seed yield was greatest in Daewonkong in both experimental fields. The greatest stem length was observed in taekwangkong and Hwanggumkong (R6) in late growth stage in paddy field. Dry weight of shoot and pod, pod number, stem length, and stem diameter were higher grown in paddy field than grown in upland. Crop growth rate (CGR) of cultivars was higher in paddy field after 8 WAS(weeks after sowing) and it was greatest at 13 WAS in Daewonkong among the cultivars. In upland field, CGR was greatest in Taekwangkong and then followed by Daewonkong and Hwanggumkong during 12 and 15 WAS. There was no significant relationships between 100-seed weight and seed yield in both experimental fields. A significant positive relationship was observed between seed number and seed yield. The correlation coefficients between leaf area and shoot dry weight were about 0.8 during the whole growth stage except 5 WAS and 4-5 WAS in paddy field and upland, respectively. This experiment was done just one year and drained paddy field condition was not satisfied drained condition successfully at 7th leaf age of soybean by the heavy rain, so we suggest that the excessive soil water reduced seed yield in paddy field and the weather condition should be considered for utilizing of these results.
