In this paper, characteristics of infrasound and low-frequency noise emission from large modern wind turbines are experimentally investigated. The sound measurement procedures of IEC 61400-11 and ISO 7196 are utilized to field test and evaluation of noise emission from each of 1.5 MW and 660 kW wind turbines using the stall regulation and the pitch control for the power regulation, respectively. It was found that the G-weighted SPLs of low-frequency noise including infrasound shows positive correlation with the wind speeds, irrespective of methods of power regulation. This highlights the potential complaint of local community against the infrasound and low-frequency noise of wind turbines. The comparison of measured data with the existing hearing thresholds and criteria curves shows that it is highly probable that the low-frequency noise from the 1.5 MW and 660 kW wind turbines in the frequency range over 30 Hz leads to the psychological complaint of ordinary adults, and that the infrasound in the frequency range from 5 Hz to 8 Hz causes the complaint by rattling the house fitting such as doors and windows.

PURPOSE: This study was conducted to identify the effects of sympathetic conversation on stress, anxiety and depression, and muscle tone in chronic stroke patients. METHODS: Patients were randomly assigned to either an experimental group (EG, n=7) or control group (CG, n=7). Both groups participated in a pretest before intervention. Subjects were asked to undergo: 1) electroencephalogram, 2) Stress Response Inventory, 3) Hospital Anxiety and Depression Scale, 4) muscle tone and stiffness testing. After the pretest, EG received sympathetic conversation and CG received a simple explanation about stroke recovery and rehabilitation. Following the intervention, both groups were immediately administered a post test. RESULTS: In EG, the electroencephalogram relative alpha power was significantly increased (p<.05), while the electroencephalogram relative gamma power was significantly decreased (p<.05). The Stress Response Inventory and Hospital Anxiety and Depression Scale scores decreased significantly in both groups (p<.05). In addition, muscle tone and stiffness decreased significantly in the EG (p<.05) CONCLUSION: The results of the present study indicate that sympathetic conversation had a positive effect on stress, anxiety and depression, and muscle tone in patients with chronic stroke. Therefore, sympathetic conversation could be used to improve not only psychological problems in chronic stroke patients including stress and anxiety, but also physical conditions including muscle tone.

The purpose of this study was to identify calls, roles and attitudes of the Christian medical staff in a modern medical system for holistic healing through belief in God's healing methods and God's view about medical treatment. The meaning of healing in the Bible is derived from Rapha in the Old Testament, it's meaning is 'heal wound', 'restore to original condition', 'repair', 'console' and 'be heal'. In the New Testament, the meaning of healing is 'to serve' and 'be in one's service' derived from Therapuein and preserve', 'rescue', 'save a life from death' derived from Sozo. The term of soteriology originated from Sozo. Therefore the meaning of the healing in the Bible is restoring original completeness to the same as Cod's characteristics. The meaning of disease is physical, psychological, social and spiritual imbalance or disharmonious. Disease is usually depravity from moral life to immoral life and abnormal life process with accompaning specific symptoms. Medical staff were called to God's work. recognized God's will for them, and absolutely leaned on God's power to intervene and work above spatial-temporal transcendently. They use spiritual power with medical treatment skills, help sick people to possibly have dynamic and individual relation with God and help to maintain their well-being and complete healing. Attitudes of medical staff were compassion and love, virtue of modesty, strong and daring, patience with belief, healing with God's word, using spiritual insight, play. using medical knowledge and techniques, continuing spiritual training, laying on of hands and repentance.
