This study was designed to investigate the effect of a year aerobic exercise training on body composition, isokinetic knee and trunk muscular strength of elders. The subjects for this study were eighty healthy elderly people who were members of seniors tower at Song-Do Hospital and didn`t have any history of cardiorepiratory disease. Subjects have been trained three times a week for a year. The exercise program was made up of a 15-minute warm-up, cool-down. Stretching was performed every eight minutes for the prevention of injuries which could occur during the main exercise and quick recovery of the used muscle. Aerobic training was performed for each 15-20minutes using the treadmill and cycle ergometer at the intensity of 50-70% HRmax. For the data, all the measurements were represented by mean and standard deviation using SAS package(version 6.12). Statistical techniques for data analysis were paired t-test to determine the difference between pre and post exercise program. The 5% level of significance was used as the critical level for acceptance of hypotheses for the study. The following results were obtained from this study. 1. There is a statistically significant difference in the VO_2max, fat mass, lean mass and %body fat both old men and women after a year training. 2. There is not a statistically significant difference in the weight, WHR and thigh circumference both old men and women after a year training. 3. There is a statistically significant difference in the right knee flexor/extensor peak torque, peak torque % body weight, total work and total work % body weight both old men and women after a year training. 4. There is a statistically significant difference in the left knee flexor/extensor peak torque, peak torque % body weight, total work and total work % body weight both old men and women after a year training.

We analyzed the chirp sound and behavior of Teleogryllus emma with observation system, which was consisted of computer, ccd-camera and microphone. Computational methods of wavelet transformation and Self-Organizing Maps (SOM) were utilized to characterized the chirp sound of insect species for automatic counting in this study. Wavelets were initially applied to feature extraction of the chirp sound. Wavelet coefficients were accordingly calculated based on the basis function (e.g., Morlet). The obtained coefficients were subsequently provided to count number of chirps in each song. Sound structure of insect specimens consisted with long chirp and short chirp and the patterns of song were grouped by frequency of long chirp and short chirp. The song patterns of insect specimens were divided by Self-Organizing Map (SOM) that was used number of chirp as input data. Application of computational methods to automatic detection of chirp sound was further discussed for obtaining objective assessment in behavior science.

Previous studies have demonstrated a decreased density of dopamine transporters (DAT) in basal ganglia in patients with idiopathic Parkinson disease (IPD) using I-n-fluoropropyl-2b-carbomethoxy-3b-(4-iodophenyl) nortropane (FP-CIT), and the reductions in striatal DAT levels were inversely correlated with the severity of motor dysfunction in IPD. However, there has been no study on the correlation of DAT levels between IPD patients with and without cognitive dysfunction. Thus, we evaluated the differences in regional DAT density in the brain of patients with IPD without dementia and those with dementia using FP-CIT positron emission tomography. We recruited 24 consecutive patients with IPD, including 7 with IPD without dementia and 17 with IPD with dementia, and 18 healthy controls. FP-CIT positron emission tomography scans were acquired 90 and 210 minutes after the FP-CIT injection. The DAT density did not differ in the caudate nucleus or the putamen between patients with IPD without dementia and those with dementia. However, the DAT density between the 2 groups with IPD demonstrated a significantly decreased density compared with that of healthy controls in the putamen. We cautiously suggest that there is no relationship between DAT density and cognitive severity because there were no significant differences in the DAT density between IPD with dementia and those without dementia.

Pseudomonas stutzeri is a Gram-negative, rod-shaped, motile, single polar-?agellated, soil bacterium that was ?rst isolated from human spinal ?uid and is widely distributed in the environment. It was isolated as an uncommon opportunistic pathogen from humans, and a few cases of P. stutzeri-induced peritonitis have been reported in patients undergoing continuous ambulatory peritoneal dialysis (CAPD). Catheter removal with antibiotic treatment is generally recommended because peritonitis by Pseudomonas species is commonly associated with catheter-related infection. Here, we describe the ?rst case of P. stutzeri-induced peritonitis in an 82-year-old woman in Korea. She had received two antipseudomonal antibiotics, an aminoglycoside (isepamicin, Yuhan corporation, Seoul, Korea) and a ?uoroquinolone (cipro?oxacin), and was successfully treated without removal of the CAPD catheter.

Extraventricular neurocytomas are rare brain tumors that have a diverse range of clinical characteristics. We describe two cases involving fluorescence-guided resection of extraventricular neurocytoma using 5-aminolevulinic acid (5-ALA) and evaluate the efficacy of the technique. We found that the tumor reactions to 5-ALA differed depending on the histologic grade. This finding shows that the 5-ALA fluorescence reaction may potentially be used as a biomarker of the clinical behavior of these tumors. To our knowledge, this is the first report in which fluorescence-guided resection was utilized for the resection of extraventricular neurocytomas.

<P>Interferon-γ release assays (IGRAs) have been incorporated into several national guidelines for latent TB infection (LTBI) diagnosis. However, their optimal application is still controversial and evolving. The aim of this study is to evaluate the performance of confirmatory IGRAs in addition to tuberculin skin tests (TSTs) in high school students with TST-positive (TST+) results who have had contact with another student who had TB (referred to in this article as 'contacts') in TB outbreaks in a high BCG-vaccinated population.</P>

Total polyphenolic, protein, lipid, and anthocyanin contents in grains of 12 Korean colored rice varieties were evaluated for their 2,2-di(4-tert-octylphenyl)-1-picrylhydrazyl) (DPPH) and 2,2-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium (ABTS) radical- scavenging activities. Three anthocyanins, cyanidin-3-O-glucoside (Cy-3-G), petunidin-3-O-glucoside (Pt-3-G),and peonidin-3-O-glucoside (Pn-3-G), were also characterized by ultra performance liquid chromatography. Among the rice varieties, ‘Heugjinju’, ‘Heugseol’, and ‘Sintoheugmi’ contained high total phenolic contents compared to other varieties. Anthocyanin content was highest in ‘Heugjinju’; no anthocyanins were detected in ‘Hongjinju’ and ‘Jeogjinju’. Highest antioxidant activity was observed in ‘Heugjinju’ and ‘Jeogjinju’ exhibited the lowest activity. To determine the correlation of total polyphenolic and anthocyanin contents to antioxidant activity, linear regression analysis was carried out. The results showed total polyphenolic content was strongly correlated with antioxidant activity, suggesting total phenolic content as key factor in antioxidant activity of colored rice. ‘Heugjinju’, ‘Heugseol’, and ‘Sintoheugmi’ could have important nutritional value.
