Purpose: This study is aimed to examine the association between initial enteral nutrition (EN) and the clinical prognosis among patients with severe and multiple traumatic injuries, and to investigate whether this association is modified by the patients' catabolic status. Methods: This was a retrospective study of 302 adult patients with severe and multiple traumatic injuries admitted between January 2017 and September 2020 at Ajou University hospital in Suwon, Korea. The initial nutritional support by EN and parenteral nutrition were monitored up to day 7 after admission. Patients were classified into "No", "Low", and "High" EN groups according to the level of initial EN. Multivariable-adjusted logistic regression and linear regression models were used to estimate the association of the initial EN levels at hospital admission with the risk of mortality, morbidities, and levels of nutrition-associated biochemical markers. Results: High EN support was associated with reduced mortality (odds ratio, 0.07; 95% confidence interval [CI], 0.02, 0.32) and lower levels of C-reactive protein (β, -0.22; 95% CI, -8.66, 1.48), but longer stay in the intensive care unit (β, 0.19; 95% CI, 1.82, 11.32). In analyses stratified by catabolic status, there were fewer incidences of hospital-acquired infections with increasing EN levels in the moderate or higher nitrogen balance group than in the mild nitrogen balance group. Conclusion: Our observation of the inverse association between levels of initial EN administration with mortality risk and inflammatory markers may indicate the possible benefits of active EN administration to the recovery process of severe and multiple trauma patients. Further studies are warranted on whether the catabolic status modifies the association between the initial EN and prognosis.

Identification of individual quantitative trait loci (QTL) is a prerequisite to application of marker-assisted selection for stern length. Two simple sequence repeat (SSR)-based linkage maps were constructed from recombination inbred line populations between cross of Keunolkong and Shinpaldalkong. Two parents used differed greatly in stem length, which were 30.57 cm and 49.75 cm in Keunolkong and Shinpaldalkong, respectively. Using the constructed maps, regression analysis and interval mapping were performed to identify QTLs conferring stem length. Four QTLs for stem length on linkage groups (LG) F, J, N and O were identified in the Keunolkong ${\times}$ Shinpaldalkong population and they totally explained 37.83% of variation for stem length. In the population, two major QTLs on LG J and O conditioning 14.25% and 10.68% of the phenotypic variation in stem length were determined and two QTLs with minor effect were detected on LG F and N. Identification of QTLs for stem length and mapping individual locus should facilitate to describe genetic mechanisms for stem length in different population. SSR markers tightly linked to QTLs for stem length allow to accelerate the elimination of deleterious genes and selection for desirable recombinants at early stage in crop breeding programs.

To obtain several foundamental information for the breeding of Korean Ginseng. 16 line selecteds in Korea were investigated and analyzed. The results obtained are as follows : 1. In all quantitative genetic characters of Korean Ginseng, the stem length showed the highest heritability(0.7050) and the leaf length the lowest(0.5674). 2. The genotypic correlation was showen the highest value (0.8649) at between the leaf length and the stem diameter and the lowest value(0.8649) at between the leaf length and the stem length, but the phnotypic correlation was shown the highest value (0.8788) at between the stem length and the stem dimeter and the lowest value (0.7950) at between the leaf length and stem length. 3. The co-heritability between the stem length and the stem diameter showed the highest value(0.6124) and that between the leaf length and the stem length showed the lowest value(0.5471). 4. The inter-class correlation among the planting location showed the highest value at the stem length and the lowest value at the stem diameter.

Purpose: The purpose of this study was to provide basic data for the guidelines for cleaning the feeding bags by comparing the level of contamination according to cleaning and disinfection methods when feeding tube of Neurosurgery Intensive Care Unit patients. Methods: This study was a true-experimental study, with 48 cases in total. The feeding bag of 48 patients were randomly assigned to detergent cleaning method or disinfectant decontamination method. The period of the experiment was January to July 2008, and enteral nutrition was given within 30 minutes for 2 hours, 4 times a day at 7AM, noon, 5PM, and 9PM for seven days. Feeding bags were cleaned after each feeding according to the assigned cleaning and disinfection method followed by microbial cultures on 4th and 8th day before the 7AM feeding. Results: After three and seven days of feeding and cleaning, the level of contamination was significantly lower when bags were cleaned with disinfectant than cleaning with detergent and tepid water. Conclusion: In cases where feeding bags are reused, for example, intensive care unit and home care settings, study findings indicate that cleaning bags with disinfectant is an effective way to prevent contamination of bags.

This experiment investigated the dwarfing effect of daminozide and chlormequat to produce high quality of spray chrysanthemum. Long neck of cut-chrysanthemum break easily. Peduncle length of the cultivar 'Biarittz' and 'Vyking' were retarded by the foliar spray treatment of $1500mg{\cdot}L^{-1}$ daminozide. Daminozide application did not affect plant growth of 'Biarittz' and 'Vyking'. However, the number of days to flowering was delayed by 3 days by daminozide application of 'Biarittz'. Length of cut flowers of 'Vyking' was decreased by the application of daminozide, while chlormequat did not affect dwarfing of peduncle length in spray chrysanthemum.

The effects of retardants B995 and CCC on the growth and yield of soybean cultivar, kwanggyo, were investigated. The 3 application times(4th, 5th and 6th trifoliate leaf stage) combined with 4 concentrations (500, 1000, 2000 and 3000 ppm) were treated, and the retardant solutions were sprayed on the foliage. Only stem length in retardants, rate of podding in application times, and, in concentrations, stem length, number of branch, number of pod per plant and grain yield, were significant. In the inhibition of stem elongation, B995 was more effective than CCC, and rate of podding was the highest in the 4th leaf-spraying. The highest concentration, 3000 ppm, was the most effective in the inhibition of stem elongation and in the increase of number of branch and pod, rate of podding, and in yield. The number of node of mainstem, dry stem weight, chlorophyll and 100 grain weight were not significant with any treat. Yield had positively correlated with number of branch and pod, and rate of podding but negatively with stem length. The retardants was thought to be considerably conducive to the increase of yield.
