Background:There are many global assessment scales for Alzheimer's disease. The clinical Dementia Rating Scale (CDR), the Global Deterioration scale (GDS) and the Blessed Dementia Rating scale have been widely used for evaluating the severity of dementia and might be useful for measuring the change of a patient's status. the CDR has been regarded as the golden standard for the severity of dementia. However, this interview-based scale takes up to 30 min for the clinician to complete, which is impractical in many clinical settings. Furthermore it is not so much sensitive for detecting the change of disease progression in each cognitive domain. We developed a brief and reliable questionnaire for evaluating the severity of dementia, called Cognitive-Clinical Dementia Rating Scale (CCDR). Methods:The CCDR consists of 15 questions that allow to assess the orientation to time, the orientation to place, the orientation to person, memory, attention, language, visuospatial function, frontal executive function, physical self maintenance, home and hobbies, community affair, the duration of dementia, mental alertness, walking ability, onset of abnormal behavior and character change. Ninety-eight probable and possible AD patients received the Clinical Dementia Rating Scale (CDR), Korean version of Mini-Mental State Examination (K-MMSE) and Cognitive-Clinical Dementia Rating Scale (CCDR). We tested validity and reliability. Results:The CCDR was significantly correlated with CDR (r=0.86, p<0.01) and K-MMSE (r=-0.88, p<0.01) and internal consistency was 0.96. Conclusion:The CCDR may be an easy and brief rating scale for the global assessment of Alzheimer's disease with excellent validity and reliability.

Background: Confrontational naming test is useful in evaluating the language function. It reveals memory and cognitive processing dysfunctions in many neurologic diseases including dementia. Although the Korean version of the Boston Naming Test (K-BNT) has been a popular and useful test, it takes much time and effort in dementia patients of moderate to severe stage of disease or in elderly individual with low educational level. So we developed the Korean Naming Test (KNT). Methods: KNT consists of relatively easy 40 items. Each item was familar materials around us and simplified figures with black thick line. Ninety two of probable Alzheimer's patients received the Korean version of Mini-Mental State Examination (K-MMSE), the Korean version of expanded Clinical Dementia Rating Scale (CDR), K-BNT and KNT. We tested reliability and validity of KNT and also evaluated scores of the KNT along with CDR. Results: The KNT correlated with K-BNT [0.75(p;0.01)], CDR [-0.49(p;0.01)], K-MMSE [0.55(p;0.01)]. The internal consistency was 0.91 (Cronbach's alpha). The KNT score decreased as the disease progressed. Conclusions: The KNT is a brief and good test for evaluating language function of moderate to severe dementia patients with low educational level. Also it is sensitive to mild stage of disease and has a excellent reliability and validity.

Background: Attention is a domain of cognitive function and a central part of cognitive impairment of Alzheimer's disease. Digit span is a brief test for attention. We evaluated attentional change in Alzheimer's disease patients by digit span and calculated sensitivity and specificity for detecting dementia and cut-off score Also we looked into the relationship between digit span and dementia screening tests. Activity of daily living (ADL) behavioral and psychological symptoms of dementia (BPSD) Methods: One hundred six patients with Alzheimer's disease and fifteen normal controls were enrolled The patients were tested by digit span and dementia screening tests. Results: Digit span forward and backward were significantly correlated with Korean version of mini-mental state examination (K-MMSE) (r=0 75. r=0.61 p<0 01) Digit span forward and backward were significantly correlated (r>0 47. p<0.01) When we defined the cut-off score of digit forward at 4 or backward at 2 or the difference at 4 It showed the sensitivity of 72% and specificity of 80% for detecting dementia Digit span deteriorated as disease progressed Conclusions: Digit span is an objective indicator of attentional deficits and provides a useful clue to the diagnosis of dementia It can be used as a quick test for dementia screening but influenced by other factors.

The purpose of this study was to examine EMG changes of the body according to method the holding during carrying object. The experiments were conducted with utilizing EMG analyses for five male and five female adults as subjects. The results were as followed. 1. The higher muscle action potential of vertical holding was shown than that of right holding when carrying objects in MMH work in proportion to the weight of the object. The came from the subjects using their brachial muscles much to maintain the angles of their wrist joints and elbow joints for keeping their stable postures while walking. 2. The higher muscle action potential of right holding was shown in right and left elector-muscles of their spines(L1-L2, L4-L5) while carrying in all stages of weights except 25kg objects than that of vertical holding. These results were caused from more use of brachial muscles than elector-muscles of spines in carrying weight objects. So vertical holding is more effective in carrying weight objects at a short distance than right holding.

Generally, tunnel lining is constructed when tunnel's strain has come to zero after excavation. Therefore, the cause of the later crack of tunnel lining is not additional loads. This study analyzes the cause of tunnel lining cracks with respect to the properties of concrete and the lining's mechanical behaviour. When lining's structural design is examined, the side pressure of concrete under construction is considered. A proper boundary condition is studied. The structural analysis method about the generation of cracks is presented, and the effect of drying shrinkage is analyzed.
