2nd dimensional GC-MS analysis of sweat volatile organic compounds prepared by solid phase micro-extraction.

The characteristics of an individual's odor from sweat, breath and skin provide important information for criminal tracking in field of forensic science. Solid phase micro-extraction gas chromatography/mass spectrometry (SPME-GC/MS) was used to determine human sweat volatile organic compounds (VOCs) profiles. The mass spectrometric analysis (with electron impact mode) followed by 2nd dimensional separation with two different GC columns (one polar and one relatively nonpolar) connected in parallel were used to identify the 574 compounds from sweat samples.

The purpose of this study was to examine effects of art and music therapy on depression and cognitive function of the elderly. This was one group pre-test, post-test design. Data were collected from January to March, 2013, from 94 elderly.

[Influencing factors on fatigue in patients with chronic obstructive pulmonary disease].

Purpose: The purpose of this study was to identify the factors influencing fatigue in patients with chronic obstructive pulmonary disease.

Methods: A descriptive correlational study design was used. A convenience sample of 125 subjects was recruited from the outpatient respiratory clinic at a large university hospital.

[Effects of walking exercise intensities on fatigue, serum lipids and immune function among middle-aged women].

Purpose: The purpose of this study was to confirm the effects of a moderate and fast walking exercise program on middle-aged women's fatigue, serum lipids and immunoglobulins.

Method: A non-equivalent control group pretest-posttest design was used for this study. The experiment was conducted for 10 weeks from May 17th to July 25th, 2004 with 44 middle-aged women, consisting of 16 for the moderate walking group, 15 for the fast walking group and 13 for the control group.
