Objectives:To identify the factors that are most significantly associated with the decline of Activities of Daily Living (ADL) status in subjects with Mild Cognitive Impairment (MCI) and early dementia of primary degenerative cause. Methods: Medical records results of neuropsychological tests and Activities of Daily Living scale were retrospectively analyzed in 134 subjects meeting the diagnostic criteria of MCI or early dementia respectively. Demographic factors memory functions depressive symptoms and executive functions of the participants were also analyzed. Results:Correlations revealed that measures of executive functions were significantly associated with ADL status in participants with MCI while both memory and executive functions were significantly associated in early demented elderly. Stroop test which measures the ability of inhibition showed the closest relation to executive function. Depressive symptoms did not have a significant influence on ADL status. Conclusion:Among participants with MCI the early functional difficulties are associated mainly with executive function which enables inhibition in particular. In participants with early dementia on the contrary the ADL status was associated with both executive function and memory. Further studies on the symptom pattern and related neuropathology in process of dementia progression are needed for Quality of Life (QoL) in elderly population.

Ministry of Environment has been designated 69 accident prevent materials, of which explosiveness or acute toxity is strong so that would cause explosion or serious accidents, as substances requiring preparation for accidents in Chemical Management Act. Among them are toxic and spread out in short time 22 chemicals, which can cause serious damage to the human body and the environment. Prevent measure from chemical release is can be the best practice, however it is also important to estimate the effect distance and minimize the damage for emergency response. In this study, we selected hydrogen chloride and hydrogen fluoride for developing the simplified estimating method and equation to calculate effect distance. Also we calculated the effect distance for toxic endpoints of hydrogen chloride and hydrogen fluoride(release rate 0.001 ㎥/s ~ 10 ㎥/s) at different ground roughness(open country and urban) based on the worst/ alternative case scenario by using the ALOHA, KORA and PHAST programs. Finally, we find the dispersion trends and suggest a simplified quick estimate formula such as y=Ax<SUP>B</SUP> (R² 0.95). The new method of this research will be easy and useful for estimating effect distance without simulating risk assessment tools.
