Purpose: The purpose of the study was to identify functional structure and patterns of dialogue sequence in conversations between elderly patients with dementia and nurses in a long-term care facility. Methods: Conversation analysis was used to analyze the data which were collected using video-camera to capture non-verbal as well as verbal behaviors. Data collection was done during February 2005. Results: Introduction, assessment, intervention, and closing phases were identified as functional structure. Essential parts of the conversation were the assessment and intervention phases. In the assessment phase three sequential patterns of nurse-initiated dialogue and four sequential patterns of patient-initiated dialogue were identified. Also four sequential patterns were identified in nurse-initiated and three in patient-initiated dialogues in the intervention phase. In general, "ask question", "advise", and "directive" were the most frequently used utterance by nurses in nurse-initiated dialogue, indicating nurses' domination of the conversation. At the same time, "ask back", "refute", "escape", or "false promise" were used often by nurses to discourage patients from talking when patients were raising questions or demanding. Conclusion: It is important for nurses to encourage patient-initiated dialogue to counterbalance nurse-dominated conversation which results from imbalance between nurses and patients in terms of knowledge and task in healthcare institutions for elders.

The aim of this study was to analyze the relationship between physical impairments and daily activities on the basis of the outcome measurements in stroke patients. Seventy-six stroke patients participated in this study. Two physical therapists evaluated 3 clinical common measurements, i.e., the Fugl-Meyer Assessment (FMA), the Berg Balance Scale (BBS), and the Functional Independence Measure (FIM). Multiple regression analysis was used, as the dependent variables were the BBS and FIM; the independent variables were post-stroke duration, FMA of Upper Extremity (FMU), and FMA of Lower Extremity (FML). In the regression equation of the BBS, the coefficient of determination ($R^2$) was .383, and the FML was found to be the most important variable for determining the BBS score. In the regression equation of the FIM, $R^2$ was .531, and the FML was found to be the most important variable for determining the FIM. These results suggest that there is a need to determine the function of activities on the basis of the physical impairments of stroke patients. More variable measurement tools on the levels of body function and structure, as well as activity limitations are required.

Myocardial perfusion imaging has been increasingly used to provide prognostic data and guidance on the choice of appropriate management of patients with known or suspected coronary artery disease. The electrocardiogram gated myocardial SPECT program is corning into wide use with an advent of $^{99m}Tc-labeled$ tracers and an improvement of SPECT machines. The gated technique permits measurement of important cardiac prognostic indicators without any further discomforts or radiation burden in patients underwent standard myocardial perfusion SPECT. In addition, gated study significantly improves diagnostic yield by reducing the number of borderline interpretations and could find myocardial stunning and viable myocardium. Gated single photon emission computed tomography (SPECT) imaging allows the automated calculation of end-diastolic volume, end-systolic volume, ejection fraction, myocardial mass and the assessment of regional wall motion and thickening, and it have dramatically improved assessment of coronary artery disease in routine nuclear practice. This allows the simultaneous assessment of both perfusion and function within the same acquisition, and serves as a cost-effective technique for providing more diagnostic data with fewer diagnostic tests. Because the diagnostic and prognostic power derived from knowledge of left ventricular function can be added to that provided by assessing myocardial perfusion, gated SPECT imaging has rapidly gained widespread acceptance and is now used on a routine clinical basis in a growing number of laboratories, including South Korea. The gated SPECT technique for measurement of left ventricular parameters has been validated against a variety of well established techniques. In this work, overview of gated myocardial perfusion SPECT focus on functional parameters is presented.

Most grading scales of Korean language proficiency tests are based on existing grading scales that are not empirically verified. The purpose of this study is to develop an empirically verified scale descriptor. The 'Performance data-driven approach' that is suggested by Fulcher (1987) was used to develop the detailed description of characteristics for each level of performance. This study is focused on the functional phase of speech samples analysis (coding data) to create explanatory categories of discourse skills into which individual observations of speech phenomena can be scored. The speech samples that were collected through this study demonstrated stages of speech that can be a foundation of a grading scale. The data used in the study was collected from 23 native speakers of Korean. Speech samples were recorded from simulated speaking tests using the 'REFUSAL' task, and transcribed for analysis. The transcript was analyzed using discourse analysis. The result showed that the 'REFUSAL' task needs to go through four functional phases in actual communication. Furthermore, this study found specific and detailed explanatory categories of discourse competence based on the actual native speaker's speech data. Such findings are expected to contribute to the development of more valid and reliable speaking assessment.

Purpose : The examine the reliability and validity of the modified Emory Functional Ambulation Profile(mEFAP) for assessing gait function in chronic stroke patients. Methods : A total of 45 stroke patients, who had a stroke more than 6 months, participated in the study. Reliability was determined by Intra-class Correlation Coefficient($ICC_{3,1}$), including Bland and Altman method (Standard Error of Measurement: SEM, Small Real Differences: SRD). Validity was examined by correlating results to the gait ability(mEFAP, Modified Motor Assessment Scale-Gait(MMAS-G), Scandinavian Stroke Scale-Gait(SSS-G), Functional Ambulation Category(FAC), 10m Waking Test(10m WT)), and Fugl Meyer-Lower/Extremity(FM-L/E), Berg Balance Scale(BBS). Results : Inter-rater reliability for the total mEFAP was High($ICC_{2,1}$=.998), and absolute reliability were excellent (SEM: 1.75, SRD: 4.85). Subjects without assistance factor performed better on all tests than did subjects who had stroke. There were significant correlations between the mEFAP and MMAS-G, SSS-G, FAC(r=-.66~-.79), 10 m WT(r=-.86), and FM-L/E, BBS(r=-.72~-.78), indicating good validity. Increased times on the mEFAP correlated with poor performance on the gait ability, motor function of lower extremity, BBS and slow gait speeds on the 10 m WT in stroke patients. Conclusion : The mEFAP can be administered easily and comprehensively. It is a reliable gait assessment tool for patients with stroke and correlated with known of function, the mEFAP may be a clinically useful measure of ambulation.

This study examines the comfort of outdoorwear by electrocardiogram (ECG) and electroencephalogram (EEG) analyses. An experiment that consisted of rest (30 min), exercise (30 min), and recovery (20 min) periods was administered in a climate chamber with 10 healthy male participants. Two kinds of outdoorwear made of 100% cotton fabrics ('Control') and specially engineered fabrics having the feature of quick sweat absorbency and high speed drying fabric ('Functional') are evaluated in the experiment. ECG and EEG signals were obtained during the rest and recovery periods for the two outdoorwear conditions. The ECG analysis identified a smaller decrement of high frequency (HF) power for the 'Functional' when compared with the 'Control' during the recovery period. Next, the EEG analysis showed that the relative band powers of slow $\alpha$ and mid $\alpha$ increased for the 'Functional' while they decreased for the 'Control' and that the ratio of $\alpha$ power to high $\beta$ power was higher for the 'Functional'. The evaluation results indicate that the participants could remain relaxed more with less stress while wearing the functional outdoorwear that demonstrated the positive effects on autonomic nervous system (ANS) activities. The present study is significant in regard that use of ECG and EEG for the assessment of wear comfort is the first in the field of clothing and textile.

Objective: This study was designed to identify and explore the pathological patterns of functional dyspepsia (FD) patients. We also evaluated the usefulness of the Pattern Identification Questionnaire by comparing it with other assessment tools for FD. Methods: We recruited 97 FD patients based on the Rome III criteria for FD diagnosis. The pathological patterns of the subjects were determined by the Pattern Identification Questionnaire. Their dyspepsia-related symptoms were assessed using the Gastrointestinal Symptom Questionnaire (GIS) and the Pyeongwi-san (Pingwei-san) Patternization Questionnaire. Depressive symptoms were evaluated with the Beck Depression Inventory (BDI) and quality of life with the Functional Dyspepsia-Related Quality of Life (FD-QoL) Questionnaire. Tongue coating was measured by the Digital Tongue Diagnosis System (DTDS). Results: The male to female ratio was 1:1.1, and the forties and fifties age groups were largest in number. The spleen deficiency and phlegm-dampness pattern was the most common pattern found among the FD patients. No significant differences in the GIS, BDI, FD-QoL, and DTDS scores were found among the five pattern types. All pattern types showed significant correlation with GIS, Pyeongwi-san Patternization Questionnaire, and FD-QoL scores. Conclusions: Pattern Identification Questionnaire can not only identify the pathological pattern types of FD patients but also evaluate the severity of their symptoms. Compared to conventional assessment tools for FD, it could enable a more dynamic evaluation of FD patients reflecting the severity of dyspeptic symptoms and the quality of life. Further studies on the Pattern Identification of FD patients are anticipated in order to improve the diagnosis and therapy for Korean FD patients.

The purpose of this study was to determine the basic materials needed for nutrition and health programs for aged people. In order to set up these programs, the nutritional habit, nutritional knowledge and functional health status (mobility, functional assessment, and falls efficacy) of the aged were measured, and their relationships were determined. Data was collected on 57 aged individuals that participated in the 'Exercise Program for the Aged' conducted by the National Health Insurance Corporation. These 57 subjects were interviewed and tested by direct measurement prior to conducting the program. The data was analyzed using the SPSS 13.0 Package. According to the results, the nutritional habit ranged from 24-50 out of 50, and the average was 37.2, which was above the middle level. The average nutritional knowledge was of 4.02 out of 5, which was considered reasonably high. Especially, more than half of these subjects were uneducated, but they had a high interest in nutrition. The average mobility was determined to be 9.2 seconds and the falls efficacy was 64.2 out of 100. In addition, subjects answered that they had a fear of falling due to low confidence, which indicates that safety education for the prevention of falls should be provided to aged individuals in the future. The results showed that notable counter-relations between nutritional habit and functional health status existed.

The study produced a functional sponge cake added with 0~20% proportion of excellently functional flaxseed powder aimed at obtaining basic data for the possibility to develop new products through a physiochemical properties assessment and a sensual assessment of the product. The water content was the lowest in the control, at 27.63%, and the 5~20% water content following the increase in added flaxseed powder failed to display a significant difference (p<0.05). The pH of the dough was 6.77~6.44, and displayed a significant difference according to the added amount of flaxseed powder (p<0.05). The specific weight of the dough appeared to be 0.40~0.51, and displayed a significant increase according to the added amount of flaxseed powder. The DPPH radical scavenging activity of the sponge cake added with flaxseed powder was 12.8%, and the plot added with flaxseed powder displayed a significantly higher percentage of 22.34~55.57% than the control plot. Crumb color change had increased values for value a and value b, and a significantly decreased L value. Texture significantly increased according to the increase in hardness, gumminess, chewiness, and cohesiveness, while springiness significantly decreased. Sensual assessment displayed a high preference for the 10% flaxseed powder additive plot in all items including appearance, taste, color, flaror, softness, and overall acceptability. The assessment of physiochemical properties and sensuality of the sponge cake added with flaxseed powder revealed that 10% flaxseed powder is suitable as the optimum proportion.
