Purpose: The purpose of this study was to understand the degree of depression, sleep quality, job stress and their association among office workers. Method: A self-administered questionnaire was distributed to 147 workers employed in 5 big enterprises, and 5 small and medium enterprises from October 21 to November 21, 2012. The questionnaires included socio-demographic and health-related characteristics, job-related characteristics, sleep quality, job stress (KOSS) and depression (CES-D). Result: Among all subjects, 23.1% was in the depression group (21 points and over in the CES-D score). Depressive level was positively correlated with job stress and quality of sleep. The adjusted odd ratio for the effects of sleep quality and job stress on depression significantly increased in the depression group compared to that of the normal group. Multiple regression analysis revealed that the following factors of influence had combined explanatory powers on depression: BMI, life satisfaction, quality of sleep, and job stress. Conclusion: The study revealed that complicated influences were exerted on the level of depression by variable factors, as well as socio-demographic characteristics, health-related characteristics, quality of sleep, and job stress. Specifically, the level of depression was influenced by the quality of sleep and job stress.

Muscle fatigue is a symptom that decreases your muscles’ ability to perform over time. It can be associated with a state of exhaustion, often following excessive sports activity or exercise. While exercise is a common cause of muscle fatigue, this symptom can be the result of other health conditions. Muscle fatigue caused by excessive activity limits activities of daily living and difficult to maintain a stable posture. Therefore, the purpose of this study was to investigate the effect of stretching, icing, and sports massage on muscle fatigue recovery.

In this study, a non-chromatographic method using tandem cavitation fractional precipitation was developed for the purifi cation of high-purity paclitaxel. Paclitaxel was purifi ed with a purity of 98.8% and an overall yield of 91.1% through a three-step fractional precipitation using acetone/pentane (1:9, v/v), methanol/water (61.5:38.5, v/v), and acetone/water (1:2, v/v) systems. In addition, the precipitation characteristics and step-by-step impurity removal behaviors were observed using RP-HPLC, and the structure of the paclitaxel purifi ed by tandem cavitation fractional precipitation was identifi ed using FT-IR spectroscopy.
