  • It has been suggested by Krag and Kountz (1950), Horvath et al. (1955) and Spurr et al. (1955) that the mechanism for prevention of heat loss is less efficient in the aged than in the young. In addition, they observed that peripheral vasoconstriction occurred more rapidly and more intensively in the aged people in response to the cold stimulus. Although it is not clear on the basis of these reports whether the Physical insulation of the aged people in cold would be different from the younger, it is evident that the vascular reactivity in response to cold seems to be altered in the aged people. Hence this investigation was undertaken to investigate the physical insulation of the aged people in a systemic manner by water immersion method which has been successfully applied to the Eskimos and Korean diving women by Rennie et al.

  • Purpose: This study was done to compare the physical injury, emotional response and unplanned self-removal of medical devices in patients with physical restraints and patients not restrained. Methods: Eighty patients admitted to the intensive care unit (ICU) of a university hospital in Seoul participated in this study. Forty patients made up each group and the group not restrained was matched with the restraint group for age and history of smoking and alcohol consumption. Data on occurrence of physical injury, intensity of anxiety, stage of agitation and unplanned self-removal of medical devices were collected by observation and medical chart review using a structured instrument. Statistical processing of collected data was done with the SPSS WIN 17.0 program. Results: The physically restrained group experienced more physical injuries and recorded significantly higher levels of anxiety and agitation than the unrestrained group. However, there were no significant differences between the groups in occurrence of unplanned self-removal of medical devices. Conclusion: Results indicate a need for critical care nurses to carefully monitor physical injuries and emotional responses of physically restrained patients and to develop nursing interventions to prevent adverse effects associated with restraint use. There is also a need to develop patient safety guidelines when using physical restraints.

  • Purpose : This study is intended to examine the repetitive transcranial magnetic stimulation on cognitive function in the focal ischemic stroke rat model. Methods : This study selected 30 Sprague-Dawley rats of 8 weeks. The groups were divided into two groups and assigned 15 rats to each group. Control group: Non-treatment after injured by focal ischemic stroke; Experimental group: application of repetitive transcranial magnetic stimulation(0.1 Tesla, 25 Hz, 20 min/time, 2 times/day, 5 days/2 week) after injured by focal ischemic stroke. To assess the effect of rTMS, the passive avoidance test, spatial learning and memory ability test were analyzed at the pre, 1 day, $7^{th}$ day, $14^{th}$ day and immunohistochemistric response of BDNF were analyzed in the hippocampal dentate gyrus at $7^{th}$ day, $14^{th}$ day. Results : In passive avoidance test, the outcome of experimental group was different significantly than the control group at the $7^{th}$ day, $14^{th}$ day. In spatial learning and memory ability test, the outcome of experimental group was different significantly than the control group at the $7^{th}$ day, $14^{th}$ day. In immunohistochemistric response of BDNF in the hippocampal dentate gyrus, experimental groups was more increased than control group. Conclusion : These result suggest that improved cognitive function by repetitive transcranial magnetic stimulation after focal ischemic stroke is associated with dynamically altered expression of BDNF in hippocampal dentate gyrus and that is related with synaptic plasticity.

  • In a demand response (DR) market run by independent system operators (ISOs), load aggregators are important market participants who aggregate small retail customers through various DR programs. A load aggregator can minimize the allocation cost by efficiently allocating its demand response resources (DRRs) considering retail customers' characteristics. However, the uncertain response behaviors of retail customers can influence the allocation strategy of its DRRs, increasing the economic risk of DRR allocation. This paper presents a risk-based DRR allocation method for the load aggregator that takes into account not only the physical characteristics of retail customers but also the risk due to the associated response uncertainties. In the paper, a conditional value-at-risk (CVaR) is applied to deal with the risk due to response uncertainties. Numerical results are presented to illustrate the effectiveness of the proposed method.

  • Background: Aconitum sinomontanum Nakai (ASN) has been reported to have analgesic effects. In this study an animal model of pharmacopuncture using ASN (100-500 mg/kg) was examined. Methods: Sprague-Dawley (SD) rats (n = 40) were randomly assigned to ASN-Low (1 mg/mL, 1.8 mL, ASN-L), ASN-Intermediate (5 mg/mL, 1.8 mL, ASN-M), ASN-High (10 mg/mL, 1.8 mL, ASN-H), negative control (0.2 mL normal saline), and positive control (0.2 mL 0.5% lidocaine) groups. All experiments were administered to the rats' left hind leg. The analgesic response was assessed by monitoring the physical (hot plate, and von Frey test) and chemical (formalin) responses to pain. Results: All ASN pharmacopuncture groups demonstrated significant differences in pain response to the hot plate test, von Frey test, and formalin test, compared to the control group (p < 0.05). The response of the ASN-M group and ASN-H groups to the hot plate, the formalin, and the von Frey tests were significantly different, compared to the lidocaine group (p < 0.05). Conclusion: ASN pharmacopuncture had a significant analgesic effect on SD rats in response to physical and chemical models of pain.

  • 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.
