Introduction: This study was conducted to investigate patients' satisfaction with hospital services at a university hospital in G city. Methods: The subjects of this study were 92 inpatients and data were collected during the period from March to April 2003. The research tool used was a 24-item scale(Cronbach' a= .768) on patients' satisfaction with two subcategories of services: 18 items on hospital human resources(a= .722) and 6 items on hospital environment(a= .700). Data were analyzed through $x^2$-test, t-test and ANOVA using SPSS/PC. Results: The level of patients' satisfaction was $38.4{\pm}3.77$ on hospital services $27.6{\pm}6.14$ on hospital human resources, and $10.8{\pm}2.39$ on hospital environment on the average. Satisfaction related to hospital human resources was higher in male subjects (t = 4.15, p = .003) and in those who stayed longer than 15 days (t= 4.404, p= .039) than the others, and also higher in those who replied that all items related to hospital facilities are satisfactory except the parking lot. Satisfaction related to hospital environment was significantly higher in more educated subjects(F = 2.945, p= .037) and in those who replied that all items related to hospital facilities are satisfactory or appropriate except the parking lot and admission procedure. Conclusions: Length of stay and the level of accessibility and appropriateness of hospital facilities were found to be factors that have significant effects on patients' satisfaction.

Near-infrared spectroscopy (NIRS) can be used to monitor brain activation by measuring changes in the concentration of oxy- and deoxy-hemoglobin (Hb) by their different spectra in the near-infrared range. Because NIRS is a noninvasive, highly flexible and portable device, it is very suitable to study brain activation when a human repeatedly performs a manipulative task, and possibly provides useful information to construct human adaptive mechatronics (HAM). There is some evidence that the dorsolateral prefrontal cortex (DLPFC) plays a major role in working memory and it is proposed that the use of working memory decreases as a human develops manipulative skills. In the present study, we investigated the activation of the dorsolateral prefrontal cortex (DLPFC) of the brain in Brodmann's areas 9 and 46 in drawing tasks to examine whether NIRS can measure the changes of DLPFC activation as a human develops manipulative skills. Subjects performed a mirror image drawing task and a square drawing task by ones' left hands. In the mirror image task the subject drew following a star shape based on a mirror image of it, but square drawing did not involve mirror image and was estimated to be simpler. The changes of the concentration of oxy-Hb was higher in the mirror image drawing than the square drawing in most subjects. The changes of oxy-Hb decreased as the subject repeated the drawing task in most subjects. In conclusion, The activation of DLPFC measured by NIRS can reflect the brain activity in the development of manipulative skills.

Background: Acute lymphoblastic leukemia (ALL) is the most common cancer diagnosed in children and represents approximately 25% of cancer diagnoses among those younger than 15 years of age. Materials and Methods: This study investigated alterations in the displacement loop (d-loop) region of mitochondrial DNA (mtDNA) as a risk factor and diagnostic biomarker for early detection and diagnosis of acute lymphoblastic leukemia. Using mtDNA from 23 subjects diagnosed with acute lymphoblastic leukemia, the first 450 bp of the d-loop region were amplified and successfully sequenced. Results: This revealed 132 mutations at 25 positions in this region, with a mean of 6 alterations per subject. The d-loop alterations in mtDNA in subjects were all identified as single nucleotide polymorphisms in a homoplasmic distribution pattern. Mutant alleles were observed in all subjects with individual frequency rates of up to 95%. Thirteen mutant alleles in the d-loop region of mtDNA occurred with a high frequency. Novel alleles and locations were also identified in the d-loop of mtDNA as follows: 89 G insertions (40%), 95 G insertions (13%), 182 C/T substitutions (5%), 308 C insertions (19%), and 311 C insertions (80%). The findings of this study need to be replicated to be confirmed. Conclusions: Further investigation of the relationship between mutations in mitochondrial d-loop genes and incidence of acute lymphoblastic leukemia is recommended.

BACKGROUND/OBJECTIVES: The anti-obesity effect of quercetin-rich onion peel extract (OPE) was suggested in rats, but information from human studies is limited. This study aimed to investigate the effects of OPE on the body composition of overweight and obese subjects. MATERIALS/METHODS: In this 12-week, randomized, double-blind, placebo-controlled study, parallel clinical trials were performed in overweight and obese Korean subjects. Randomly assigned subjects were instructed to take daily either the placebo (male, 6 and female, 30) or OPE capsules containing 100 mg of quercetin (male, 5 and female, 31). Body composition was measured by using bioimpedance and dual-energy X-ray absorptiometry (DXA). Resting energy expenditure (REE) and respiratory quotient (RQ) were evaluated by using indirect calorie measurement methods. Fasting blood levels of glucose, insulin, lipids, and leptin were determined. RESULTS: Quercetin-rich OPE supplementation significantly reduced the weight and percentage of body fat as measured by DXA (P = 0.02). These effects were not shown in the control group. Levels of blood glucose (P = 0.04) and leptin (P = 0.001 for placebo, P = 0.002 for OPE) decreased in both groups. Significant increases in REE and RQ were observed in both groups (P = 0.003 for placebo, P = 0.006 for OPE) and in the OPE group alone (P = 0.02), respectively. CONCLUSIONS: Quercetin-rich OPE supplementation changed the body composition of the overweight and obese subjects. This result suggests a beneficial role of the anti-obesity effect of OPE human subjects.

The present study was investigated on type 2 diabetics' actual status of anti-diabetic functional food intake by patients who came to oriental medicine clinics in Daejeon. The male was 37.3% and female was 62.7% of the subjects. The onset of the disease was most common in the age of 50's. Also 40% of the subjects have been suffering for more than 5 years. 35.7% of men, 53.2% for women had family history. Also 61.5% of the patients chose to carry out both diabetic therapy and exercise at the same time. 69.3% of the subjects have had experiences in anti-diabetic functional foods. Anti-diabetic functional foods used to surveyed people were bean, ginseng, and ginseng steamed red of which efficacies were already well known. Besides these foods, other foods such as loach, crucian carp were also used as anti-diabetic foods, but their benefits as anti-diabetic functional foods are not yet fully investigated. Subjects first knew about the therapy because friends or relatives recommended to them and most of them have used for 6 months to 1 year. However, 78.9% of subjects answered 'not so effective' in a question about satisfaction of anti-diabetic functional food. Although many of the patients have tried taking functional foods, they only use them for short period of time and they don't show prominent effect. Therefore these results suggest that in order to use scientifically studied functional foods, education about anti-diabetic functional foods should taken.

This study was conducted to investigate the dietary behavior of day-care center teachers and their meal attitudes during meal time in Jeonju area. Self administered questionnaires were collected from 266 day-care center teachers who worked in a national(public) or private day-care center. The Statistical data analysis was conducted using SPSS v. 12.0. All subjects were women, and 64.7% were married(p<0.001), over more than 60% were junior college graduates(p<0.05), and 73.7% had salaries greater than 1,000,000 won(p<0.001). The breakfast skipping ratio of the subjects was very high, and about 66.5% of the respondents had irregular meals. The snack intake ratios of the subjects in private day-care centers were higher than the subjects in national(public) day-care centers(p<0.001). Approximately 56% of the subjects responded that education about eating is very important for providing balanced nutrition to young children. About 84% of subjects had no experience with the continuing-education program for teachers(p<0.01), and they wanted to know more about balanced nutrition. The meal attitude education score during meal time was $4.53{\pm}0.36$. The relationship between meal attitude education and the dietary behavior of day-care teachers was significantly different based on the "frequency of overeating"(p<0.05) and "self-recognition of eating habit"(p<0.05). These findings suggest that a nutrition education program for day-care center teachers should be developed so that they can effectively manage meal attitude education for young children and provide good nutrition for themselves.

Human upright standing posture in the sagittal plane is studied, when it exposed in the antero-posterior vibration. A two link inverted pendulum model is considered and described its functional behavior in terms of ankle and hip joint according to the dominant joints that provides the largest contribution to the corresponding human reactionary motion. The data is analyzed, both in the time domain and the frequency domain. Subjects behave as a non-rigid pendulum with a mass and a spring throughout the whole period of the platform motion. When vision was allowed, each segment of body shows more stabilized.
