The sap outflow characteristics of Juglans sinensis and J. mandshurica were investigated to evaluate the optimum pruning period of walnut tree that there is a sap spill on dormant. The total period of sap outflow were 34 days for both J. sinensis and J. mandshurica. Total amount of sap outflow per tree in J. sinensis and J. mandshurica were 2,922 mL/tree and 3,135 mL/tree, respectively and the period of sap outflow and non sap outflow between two species were similar. ANOVA analysis showed that the amount of sap outflow was significant differences with day of sap outflow but there were no significant differences between species. From the correlation analysis between air-temperature and sap outflow, daily minimum temperature showed a positive correlation at the 1% level of significance (r=0.56 and r=0.46) for both J. sinensis and J. mandshurica. When branch of walnut tree that diameter is 5 cm cut on the period of sap outflow, the sap flowed down the longest period (48 days) but the sap outflow was not observed after budburst. Therefore, our study supported that the pruning have to avoid the period of sap outflow to reduce sap outflow of walnut tree.

Angelica gigas Nakai (Korean danggui), a member of the Umbelliferae family, is a Korean traditional medicinal plant whose roots have been used for treating gynecological diseases. Transcriptomics is the study of the transcriptome, which is the complete set of RNA transcripts that are produced by the genome, using high-throughput methods, such as microarray analysis. In this study, transcriptome analysis of A.gigas Nakai was carried out. Transcriptome sequencing and assembly was carried out by using Illumina Hiseq 2500, Velvet and Oases. A total of 109,591,555 clean reads of A. gigas Nakai was obtained after trimming adaptors. The obtained reads were assembled with an average length of 1,154 bp, a maximum length of 13,166 bp, a minimum length of 200 pb, and N50 of 1,635 bp. Functional annotation and classification was performed using NCBI NR, InterprotScan, KOG, KEGG and GO. Candidate genes for phenylpropanoid biosynthesis were obtanied from A.gigas transcriptome and the genes and its proteins were confirmed through the NCBI homology BLAST searches, revealing high identity with other othologous genes and proteins from various plants pecies. In RNA sequencing analysis using an Illumina Next-Seq2500 sequencer, we identified a total 94,930 transcripts and annotated 71,281 transcripts, which provide basic information for further research in A.gigas Nakai. Our transcriptome data reveal that several differentially expressed genes related to flower color in A.gigas Nakai. The results of this research provide comprehensive information on the A.gigas Nakai genome and enhance our understanding of the flower color related gene pathways in this plant.

Background : The Sequential Organ Failure Assessment (SOFA) score can help to assess organ failure over time and is useful to evaluate morbidity. The aim of this study is to evaluate the performance of SOFA score as a descriptor of multiple organ failure in critically ill patients in a local unit hospital, and to compare with APACHE III scoring system. Methods : This study was carried out prospectively. A total of ninety one patients were included who admitted to the medical intensive care unit (ICU) in Chuncheon Sacred Heart Hospital from May 1 through June 30, 2000. We excluded patients with a length of stay in the ICU less than 2 days following scheduled procedure, admissions for ECG monitoring, other department and patients transferred to other hospital. The SOFA score and APACHE III score were calculated on admission and then consecutively every 24 hours until ICU discharge. Results : The ICU mortality rate was 20%. The non-survivors had a higher SOFA score within 24 hours after admission. The number of organ failure was associated with increased mortality. The evaluation of a subgroup of 74 patients who stayed in the ICU for at least 48 hours showed that survivors and non-survivors followed a different course. In this subgroup, the total SOFA score increased in 81% of the non-survivors but in only 21% of the survivors. Conversely, the total SOFA score decreased in 48% of the survivors compared with 6% of the non-survivors. The non-survivors also had a higher APACHE III score within 24 hours and there was a correlation between SOFA score and APACHE III score. Conclusion : The SOFA score is a simple, but effective method to assess organ failure and to predict mortality in critically ill patients. Regular and repeated scoring enables patient's condition and clinical course to be monitored and better understood. The SOFA score well correlates with APACHE III score.

In this study, we examined the changes of fruit number and fruit weight according to the length of bearing branch of Actinidia arguta and identified the correlation the length of bearing branch and fruit characteristics. The fruit weight and the fruit number of A. arguta bearing branch which length are below 15 cm and over 30 cm were 11.7 g, 4.3 and 12.3 g, 13.8, respectively. From the results, the bearing brach which length was below 15 cm must be removed in winter season pruning. The pruning experiment was conducted to examine the effects on fruit quality and yield of A. arguta. Total fruit yield of heavy-pruning was $14.3{\pm}1.5kg/tree$. The production of fruits over 15 g wight was $8.2{\pm}0.9kg/tree$, that of fruits between 10 g to 15 g was $4.0{\pm}0.7kg/tree$, and that of fruit below 10 g was $2.1{\pm}0.3kg/tree$, respectively. Average fruit yield of nonpruning was $26.7{\pm}2.1kg/tree$, fruit yield over 15 g, between 10 g and 15 g, and below 10 g were $2.5{\pm}0.5kg/tree$, $19.2{\pm}1.4kg/tree$, and $5.0{\pm}0.6kg/tree$, respectively. Distribution of high quality fruit (over 15 g) showed that non-pruning was almost 15~16 g but pruning was evenly distributed between 15 g and 20 g. According to the survey, The high quality fruit (over 15 g) would not be harvested if the winter pruning is not applied in the A. arguta cultivation.

Background : Recurrent pneumonia in adults is not uncommon. However, there is no domestic data about recurrent pneumonia in adults. Therefore, we investigated the associated diseases and clinical findings of recurrent pneumonia in adults. Methods : Among 5513 patients who were treated in five teaching hospitals of Hallym medical center?over a 5-year period, we retrospectively reviewed the medical records of the 58 who were compatible with diagnostic criteria of recurrent pneumonia. Results : The number of patients with recurrent pneumonia was 58 (1.05%, 58/5513) during the 5 years. Thirtyseven patients were male and 21 were female. Mean age was 66.4 (${\pm}14.9$) years. Median interval between each pneumonic episode was 18.5 months. Associated diseases were 25 cases of respiratory diseases, 13 of heart diseases, 13 of diabetes mellitus, 7 of lung malignancies, 11 of malignancies other than lung, 7 of neurologic disease, and 8 of miscellaneous diseases. Three cases had no underlying illness. Of the 8 cases with 2 or more times of recurrence, 4 were associated with respiratory diseases, 2 with aspiration pneumonia due to neurologic diseases, 1 with heart disease and 1 with no underlying illness. Recurrent pneumonic episodes affecting the same location were 30 of the total recurrent pneumonic episodes (30/67, 47.8%) and common associated diseases were respiratory diseases including lung malignancies. The etiology of recurrent pneumonia was Streptococcus pneumoniae, methicillinresistant Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumoniae, atypical organisms, etc. Conclusion : Recurrent pneumonia in adults had a low incidence rate compared with children, but most cases had associated illness. Respiratory diseases including lung cancer were the most common associated illness of recurrent pneumonia.
