Purpose: This study was to investigate the relationship among the symptom recognition, health behavior compliance, and the hospital arrival time to identify factors influencing the hospital arrival time in patient with acute myocardial infarction (AMI). Methods: The subjects of this study were 200 patients with AMI in C hospital in D city. Data were analyzed using descriptive statistics, independent t-test, One way ANOVA, Pearson's correlation coefficients, and stepwise multiple liner regression tests. Results: Level of symptom recognition and health behavior compliance was low. The median value of hospital arrival time was 4.48 hours (ST-segment Elevation Ml was 2.43 hours and Non ST-segment Elevation MI was 7.83 hours). Among the studied factors, only symptom recognition had a statistically significant positive correlation with health behavior compliance (r=0.38, p<.001). Factors influencing the hospital arrival time were MI classification, diabetes mellitus (DM) and transport vehicle to the 1st hospital, and they accounted for 13% of the variance for hospital arrival time in AMI patients. Conclusion: To prevent the delay of hospital arrival time in MI patients, a more robust nursing strategic intervention according to MI classification and DM is necessary; further education on the importance of transportation utilization is also mandated.

Background: The purpose of this study was to analyze the applicability of dried jujube (Zizypui Fructus) distributed by size as a functional food material and herbal medicine by evaluating its physicochemical characteristics and betulinic acid content. Methods and Results: It was shown that the carbohydrate content of in jujube fruit significantly increased with fruit size; 81.42% for large, 79.83% for medium, and 76.39% for small. Similarly, the dilute ethanol extract content of each group was 72.48% (large), 69.56% (medium), and 64.16% (small). A free sugar analysis indicated that glucose, fructose and sucrose were found in quantitieds proportional to jujube fruit size, the total free sugar values were 68.85%, 63.93%, and 57.37% for large, medium, and small fruit sizes respectively. The betulinic acid content for large, medium, and small fruit was 0.50 mg/g, 0.54 mg/g, and 0.58 mg/g respectively, indicating that smaller jujube contained a higher amount of betulinic acid. Conclusions: It is considered that betulinic acid content could be used as a criteria for jujube fruit quality control.

Galgeuntang water extract exhibited a strong free radical scavenging activity and reducing power determination. However, a gradual increase in the free radical scavenging activity and reducing power determination was obtained with increasing concentrations. The highest radical scavenging activity was shown by the water extract from Galgeuntang (116.93 ${\mu}g$/mL) and the water extract from Cinnamonum cassia Presl. (95.01 ${\mu}g$/mL). These results of phenolic and flavonoid contents of the extracts indicated that the strong radical scavenging activity of the Cinnamonum cassia Presl. extract might be in part due to the phenolic compounds. The correlation coefficient between TPC and DPPH ($r^2$ = 0.9312), TFC and DPPH ($r^2$ = 0.9677), showed positive correlation among total phenolic/flavonoid contents and antioxidant activity. These results suggest that Galgeuntang has a potential antioxidant activity.

Twelve mecoprop-degrading bacteria were isolated from soil samples, and their genetic and phenotypic characteristics were investigated. Analysis of 16S rDNA sequences indicated that the isolates were related to members of the genus Sphingomonas. Ten different chromosomal DNA patterns were obtained by polymerase-chain-reaction (PCR) amplification of repetitive extragenic palindromic (REP) sequences from the 12 isolates. The isolates were found to be able to utilize the chiral herbicide meco-prop as a sole source of carbon and energy. While seven of the isolates were able to degrade both (R)-and (S)-mecoprop, four isolates exhibited enantioselective degradation of the (S)-type and one isolate could degrade only the (R)-enantiomer. All of the isolates were observed to possess plasmid DNAs. When certain plasmids were removed from isolates MPll, MP15, and MP23, those strains could no longer degrade mecoprop. This compelling result suggests that plasmid DNAs, in this case, conferred the ability to degrade the herbicide. The isolates MP13, MP15, and MP24 were identified as the same strain; however, they exhibited different plasmid profiles. This indicates that these isolates acquired dif-ferent mecoprop-degradative plasmids in different soils through natural gene transfer.

The purpose of this study is to examine the effect of massage therapy and exercise therapy on body composition and blood cholesterol in the obese women. Sixteen college women were randomly assigned to aged $20.1{\pm}2.7$ years who had not exercised regurlarly, volunteered to participate in the present study as subjects. They completed a 12 weeks massage therapy and exercise therapy performed 3 times/week, for 60min/session. Massage put in exercise treatment effect of 12 weeks in BMI has shown a significant decrease those are before test $25.1{\pm}2.2$ to after test $23.7{\pm}3.2$(p<0.05). The waist measure/height has a difference by before test r=0.5 to after a test r=0.47, and waist measure/hips measure by before test r=0.8 to after test r=0.75. A total cholesterol(TC) average value has $187.6{\pm}36.9$ before test to $168{\pm}32.4$(p<0.05) after test, a significant difference. Also average value of LDLC has $114{\pm}33.8$ before test to $99.2{\pm}30.4$(p<0.05) that shows a difference, but HDLC was $52{\pm}7.5$ before test to $52.3{\pm}7.7$(p<0.05) after test which means a none difference. HDLC does not have any difference but total cholesterol and LDLC were significantly different. It was a short program of 3 times a week, 60 min/session but, a dance meditation exercise program with high strength self massage had given a big effect in consideration. Using these scientific studies data, wish a program related by obese could make an activation in a beauty part.

Purpose: The cow's milk-related-symptom-score (CoMiSS) tool was developed as an awareness tool for the assessment of cow's milk-related symptoms in infants or children. Fecal calprotectin (FC) is a noninvasive biomarker of gut inflammation that can be measured in serum and stool. This study aimed to investigate the relationship between FC levels and CoMiSS scores in infants with cow's milk protein allergy. Methods: Infants (aged 6-12 months) who were allergic to cow's milk protein were enrolled prospectively. Following completion of the CoMiSS scoring, the infants were divided into group 1 (positive CoMiSS scores ≥12) and group 2 (negative CoMiSS scores <12). FC was measured using immunoassay. Results: Of the 120 infants enrolled in this study, 60 (50.0%) had positive CoMiSS scores (group 1), while 60 (50.0%) had negative scores (group 2). The mean FC level was higher in the infants in group 1 than those in group 2 (2,934.57 ㎍/g vs. 955.13 ㎍/g; p<0.001). In addition, there was a positive correlation between FC and CoMiSS scores (R=0.168, p<0.0001). A FC level of 1,700 ㎍/g provided a sensitivity of 98.3%, specificity of 93.3%, and accuracy of 95.8% for the diagnosis of cow's milk protein allergy (CMPA). Conclusion: FC measurement may have a role in the assessing infants with CMPA.

When researchers plan R&D projects, they usually use patent map or paper map for the objective decision-making, but in traditional korean medicine field, domestic patents and papers have been mainly proposed as results of many R&D projects, while most of patent or paper map tools support international patents and SCI papers, respectively. Therefore, as an alternative one KIOM constructed the project map which can provide the technology landscape for R&D project information in traditional korean medicine field. But the functions of the system is limited to the search and analysis with chart. So sophisticated analysis results are hard to get from the existing system. This research's goal is to upgrade the web based project map analysis system to provide researcher rich functionality and advanced analysis tools.
