We monitored antibiotic resistance of Escherichia coli isolates from healthy volunteers of community and hospital patients from February to July in 2006. From disc diffusion test on 4915 E. coli isolates from healthy volunteers of the community, the resistance rates were as follows; tetracycline resistant, 46.6%; ampicillin resistant, 41.1%; ticarcillin resistant,37.9%. From disc diffusion test on 120 E. coli isolates from hospital patients, the resistance rates were as follows: ampicillin resistant, 66.9%; ticarcillin resistant, 63.8%; tetracycline resistant, 47.2%. Extended spectrum $\beta$-lactamase producing E. coli were isolated 0.6% and 4.1% from healthy volunteers and hospital patients.
Objectives: The objective of the present study was to assess the factors that influence the health of workers, especially nurses, and to propose methods for health management. Methods: A total of 246 nurses were surveyed to ascertain the health status score, Sasang constitution diagnosis, health-related life and job factors, psychosocial stress, and job stress. Depending on their health status score, the subjects were categorized into unhealthy, intermediate, or healthy groups, and each factor was compared with the stress score of the groups. Further, each Sasang constitution factor was also compared with the stress scores. Results: Analysis based on the health status scores indicated that the patients in the intermediate group were older and had longer tenure than those in the unhealthy or healthy groups. The healthy group had higher number of married individuals, and they were subjectively assessed as healthy. Patients in this group were more satisfied with their work than those in the unhealthy group. Analysis of the Sasang constitution showed that a lower percentage of individuals with a Soeumin constitution were married, and most considered themselves to be unhealthy during the subjective health assessment. Conclusions: The findings of this survey revealed that in order to maintain health, efforts should be made to improve the work environment, achieve health confidence, and practice health behavior while considering one's own body, mental state, and constitution.
Objectives : The characteristic of meridian system has been similar to this of electric potentials in human body. Therefore to measure the electric potentials in healthy volunteers and patients, and to find out the characteristic of meridian system and also to do that of differences between them. Methods : Twenty-nine healthy volunteers, thirty patients diagnosed as a cerebral infarction and wind-syndrome caused by hyperactivity of the liver-yang(肝陽化風) were examined into electric potential of well(井穴) and sea(合穴) points in branches of the twelve meridians by physiograph. Results : Measurements were analyzed by factor analysis, then we obtained that both the right and the left electric potential of well and sea points in branches of the twelves meridians in healthy volunteers were divided into two factors, hand meridian and foot meridian. Where as the left electric potential of those in patients with cerebral infarction were divided into three factors, one is foot meridian, another is hand meridian with the exception of large intestine meridian, and the other is large intestine meridian and also the right electric potential were divided into three factors, foot meridian, hand meridian with the exception of large intestine and lung meridian, and large intestine and lung meridian. Conclusions : In the results, healthy volunteers differ from patients in characteristic of electrical potentials, which means that we are able to catch the characteristic of meridian system by electrical potentials of well and sea points.

Objectives : This study was designed to evaluate the changes of autonomic nervous system by heart rate variability(HRV) test on the musculoskeletal pain patients treated with acupuncture on the Back-su points and the unfixed points, and untreated healthy adults. Methods : This clinical study have been carried out with 64 cases of musculoskeletal pain patients and 26 healthy adults. 35 patients were treated with acupunctureon on the Back-su points(Group I) and 26 patients were treated on the Unfixed points(GroupII), and two groups were tested by HRV at pre and post acupuncture treatment. 26 healthy adults(GroupIII) were tested twice by HRV without any stimulation. Results : In Group I, VAS was decresased $5.83{\pm}1.62$ to $5.17{\pm}1.89$ significantly(p<0.05) after acupuncture treatment, and LF/HF ratio was decreased significantly(p<0.05) as compared with healthy control Group. In GroupII, SDNN & RMSSD were increased singnificantly(p<0.05) as compared with other Groups. in Group I & II, MHRT was decreased significantly(p<0.05) as compared with healthy control Group. Conclusions : These results suggest that acupuncture treatment on the Back-su points was able to reduce the pain, suppress the sympathetic activities and enhance the parasympathetic activities in musculoskeletal patients.
The purpose of this study is to research the relationships among LOHAS trends, healthy menu and healthful dietary behavior of university students as one of the performance variables. For this research, sample group was composed of the university students in Daegu & Gyeongbuk areas. The study required the analysis derived from a hypothesis, literature reviews and data collected. It used SPSS 14.0 from 626 university students. First, LOHAS trends was found to have positive effects on healthy menu and reusing had only positive effects on nutrition elements and nutritional value. On the other hand, durability was found not to affect nutrition elements and nutritional value significantly. Second, reusing and durability were found to have significant effects on healthful dietary behavior. Third, nutrition elements and nutritional value were found to have positive effects on healthful dietary behavior. Based on the results of this study, it is suggested that food industry managers should pay particular attention on the eating behavior of university students in developing healthy menu.
This study was conducted to examine the differences in perceived body weight and image and various lifestyles based on the self-rated health of university students when gender was adjusted. Five hundred fifty-five participants were asked their perceived health condition, and 58, 289, 160 and 48 students answered themselves as "very healthy", "healthy", "normal", and "unhealthy", respectively. As compared to the other 3 groups, "unhealthy" group showed higher proportions in dissatisfaction of body weight and negative perception of body image (P < 0.01). As health related lifestyles, "very healthy" group reported longer sleeping time than "unhealthy" group (P < 0.05), and had a higher proportion of people with regular exercise. Among the dietary behaviors, the frequencies of followings significantly different among the groups: "Regularity of meal time" (P < 0.01), "Eat protein foods more than twice a day" (P < 0.001), "Eat vegetables" (P < 0.01), "Eat fruit and fruit juice" (P < 0.01), "Eat vegetable oil added foods" (P < 0.01), "Eat seaweed" (P < 0.01), "Eat breakfast" (P < 0.01), "Modulation in animal fat and high in cholesterol intake" (P < 0.01). Particularly, higher proportion of subjects answered "very healthy" had higher frequencies (6-7 times/week) of these dietary behaviors. Overall results suggest that healthy lifestyle including adequate sleeping time, regular exercise, and good dietary behaviors might be potential factors affecting positive perception of health. In addition, positive perception of body weight and image were related with positive perception of health.
The objective of this study was to develop nutrition education materials for older adults, 'nutritional management for healthy aging'. A booklet and four leaflets were developed based on lesson plans. Topics of the lesson plans included eating habit assessment. Korean food guide pyramid, meal planning, eating sensibly and weight management. The titles of the leaflets were 'Eating right for healthy aging', 'Eat calcium-rich foods', 'Enjoy fruits & vegetables' and 'Weight management'. Illustrations and icons appropriate to the texts were designed using illustrator 9.0 and Photoshop 6.0. Booklet (letter size, 5 chapters, 44 pages) and leaflets (B4 size, 6 sections) focused on modifying undesirable eating habits, providing practical tips for desirable behaviors, and behavioral modification such as recording in a food diary, goal setting and increasing self-efficacy. The drafts were pilot-tested by interviews with older adults(n=10), and minor changes were made. The characteristics of revised materials are as follows; i) materials focused on providing desirable eating behaviors for healthy aging, ii) messages were simple and specific, iii) large fonts(13 pt) were used and materials included interesting pictures and illustrations, iv) materials provided tips for balanced diets and recipes fur older adults, v) materials included sections for participation of learners including assessment of nutritional risk factors and obesity, meal planning and games. The revised materials are self-explanatory and can be used by older adults and in nutrition education for older adults.
This study has investigated the effect of a potent bioflavonoid, troxerutin, on diabetes-induced changes in pro-inflammatory mediators and expression of microRNA-146a and nuclear factor-kappa-B (NF-κB) signaling pathway in aortic tissue of type-I diabetic rats. Male Wistar rats were randomly divided into four groups (n = 6/each): healthy, healthy-troxerutin, diabetic, and diabetic-troxerutin. Diabetes was induced by streptozotocin injection (60 mg/kg; intraperitoneally) and lasted 10 weeks. Troxerutin (150 mg/kg/day) was administered orally for last month of experiment. Inflammatory cytokines IL-1β, IL-6, and TNF-α, as well as intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule (VCAM), cyclooxygenase-II (COX-II), and inducible-nitric oxide synthase (iNOS) were measured on aortic samples by enzyme-linked immunosorbent assay. Gene expressions for transcription factor NF-κB, interleukin-1 receptor-associated kinase-1 (IRAK-1), TNF receptor-associated factor-6 (TRAF-6), and microRNA-146a were determined using real-time polymerase chain reaction. Ten-week diabetes significantly increased mRNA levels of IRAK-1, TRAF-6, NF-κB, and protein levels of cytokines IL-1β, IL-6, TNF-α, adhesion molecules ICAM-1, VCAM, and iNOS, COX-II, and decreased expression of microRNA-146a as compared with healthy rats (p < 0.05 to p < 0.01). However, one month treatment of diabetic rats with troxerutin restored glucose and insulin levels, significantly decreased expression of inflammatory genes and pro-inflammatory mediators and increased microRNA level in comparison to diabetic group (p < 0.05 to p < 0.01). In healthy rats, troxerutin had significant reducing effect only on NF-κB, TNF-α and COX-II levels (p < 0.05). Beside slight improvement of hyperglycemia, troxerutin prevented the activation of NF-κB-dependent inflammatory signaling in the aorta of diabetic rats, and this response may be regulated by microRNA-146a.
Purpose: The purpose of this study was to examine the correlations among the resting physical factors related to a six-minute walk test (6MWT) and to determine the effects of the resting physical factors on the distance and intensity related to the 6MWT in healthy female subjects. Methods: A total of 43 healthy female subjects ($22.84{\pm}3.90yrs$) participated in this study. They performed the 6MWT, and the physical factors related to the 6MWT were assessed. SPSS 20.0 was used to analyze the data, and the mean and standard deviation were calculated, and the collected data were analyzed by the Pearson's correlation coefficient (among physical factors related to 6MWT) and independent t-test (between six-minute walk distance [6MWD] groups and six-minute walk intensity [6MWI] groups). Results: The 6MWD had a significant negative correlation with the resting HR (beat/min) in healthy female subjects (r=-0.49, p<0.05). The 6MWI had a significant negative correlation with the resting systolic blood pressure (SBP) (r=-0.45, p<0.01). A comparison of the 6MWD revealed the long distance group (LDG, 700-799 m) to be significantly higher than the middle distance group (MDG, 600-699 m) in the 6MWI (%), %predicted distance (%), predicted VO2max (mL/kg/min), resting HR (beat/min), and resting SBP (mmHg)(p<0.05). In the comparison of 6MWI, the moderate intensity group (MIG, 64-75%HRmax) was significantly lower than the low intensity group (LIG, 50-63%HRmax) in the resting SBP (mmHg) (p<0.05). Conclusion: These results suggest that the resting physical factors are related to the 6MWD and 6MWI of the 6MWT in healthy females. In particular, SBP is associated with not only the 6MWD but also the 6MWI in 6MWT.
Objectives: The purpose of this study is to gain the objective indicators for the classification of hypertension by oriental medical pulse diagnosis, through finding out the parameters which can distinguish the pulse of hypertensive patient from that of normal subject, and characterizes the wiry pulse of hypertension. Methods: 30-59 yr, male, 946 healthy volunteers and 35 hypertensive patients were enrolled in this study. All the hypertensive patients were taking medicine to control the blood pressure and the blood pressure of the hypertension group was not statistically different from that of the normal healthy group. Data were acquired using 3 dimensional pulse imaging analyser(DMP-3000, DAEYOMEDI, KOREA) and analysed according to the age bands and the applied pressure levels. Results: 1. RAI/t, w/t and t2/t decreased with the levels of applied pressure and increased with age in the normal healthy group, not in the hypertension group. 2. RAI/t, w/t, t2/t were significantly higher in the hypertension group than the normal healthy group in the 30-age band, and elasticity coefficient was higher in the hypertension group than the normal healthy group in the 40-age band. 3. Researches on the patients without hypotensive agents are needed to figure out whether these parameters are the components of hypertensive wiry pulse. Conclusions: Analysing the radial pulse at 5 applied pressure levels using 3 dimensional pulse imaging analyser may be useful to differentiate the pulses of the hypertensive patients from those of the normal subjects, and characterize the hypertension.
