Tei-index has been reported as one of reliable echocardiographic factors for evaluating cardiac function in human and small animals. In this study, Tei-index were measured and evaluated with other echocardiographic parameters in normal thirteen beagle dogs and thirty-one dogs with mitral valve degeneration. Normal range of Tei index with tissue Doppler obtained at septum and left ventricular free wall was $0.58{\pm}0.07$ and $0.60{\pm}0.07$, respectively. The values between septum and left ventricular free wall did not show significant difference. Tissue Doppler derived tei index showed better reproducibility and significantly lower values than the results obtained by pulsed wave Doppler. Tei index obtained in either method increased with the progression of clinical signs. Therefore, the increase of Tei index in dogs with mitral regurgitation is thought to be an useful factor reflecting left ventricular dysfunction.

Fragility as one of the most effective methods to evaluate seismic performance, which is greatly affected by damage index. Taking a multi span continuous rigid frame offshore bridge as an example. Based on fragility and reliability theory, considering coupling effect of time-varying durability damage of materials and time-varying attenuation effect of damage index to analyze seismic performance of offshore bridges. Results show that IDA curve considering time-varying damage index is obviously below that without considering; area enclosed by IDA of 1# pier and X-axis under No.1 earthquake considering this effect is 96% of that without considering. Area enclosed by damage index of 1# pier and X-axis under serious damage with considering time-varying damage index is 90% of that without considering in service period. Time-varying damage index has a greater impact on short pier when ground motion intensity is small, while it has a great impact on high pier when the intensity is large. The area enclosed by fragility of bridge system and X-axis under complete destruction considering time-varying damage index is 165% of that without considering when reach designed service life. Therefore, time-varying attenuation effect of damage index has a great impact on seismic performance of bridge in service period.

Objectives : This study was designed to evaluate patient satisfaction of Korean medicine therapy using treatment tool by psychological type. Methods : 48 subjects were participated in this study. Before a treatment, we analyzed a patient's phychological type first by using a questionnaire. And then we divided 3 groups which were called a rational sympathy module group, emotional sympathy module group, control group. Manner of medical consultation according to patient's phychological type was carried out in all groups. After all treatment, we conducted a survey about medical service perception index, patient happiness index, medical satisfaction index. To evaluate a satisfaction degree, we analyzed results of survey statistically. Results : The results of the analysis, both rational sympathy module group and emotional sympathy module group got a higher score than control group statistical significantly on medical service perception index. Emotional sympathy module group got a higher score than control group statistical significantly on patient happiness index and medical satisfaction index. But rational sympathy module group only had a higher tendency than control group on patient happiness index and medical satisfaction index. Emotional sympathy module group got a higher score than rational sympathy module group on medical service perception index, patient happiness index and medical satisfaction index. Conclusions : Korean medicine therapy using treatment tool by psychological type consisted of patient's phychological type questionnaire and manner of medical consultation could improve a patient's satisfaction. It was more effective in emotional sympathy module group than rational sympathy module group.

This study proposes phonation type index k as a descriptor of the overall spectral tilt, which is free from the effects of fundamental frequency and vowel quality. The newly proposed phonation type index k presents a simple and single measure of the overall spectral tilt. Phonation type index k can be applied to speech technology. It can also be used in diagnosing patients voice qualities in speech pathology. The distribution of phonation type index k, which is speaker-dependent, may be useful in forensic phonetics and voice recognition as an indicator of speaker identity.

The multiplicative version of Wiener index (${\pi}$-index), proposed by Gutman et al. in 2000, is equal to the product of the distances between all pairs of vertices of a (molecular) graph G. In this paper, we first present some sharp bounds in terms of the order and other graph parameters including the diameter, degree sequence, Zagreb indices, Zagreb coindices, eccentric connectivity index and Merrifield-Simmons index for ${\pi}$-index of general connected graphs and trees, as well as a Nordhaus-Gaddum-type bound for ${\pi}$-index of connected triangle-free graphs. Then we study the behavior of ${\pi}$-index upon the case when removing a vertex or an edge from the underlying graph. Finally, we investigate the extremal properties of ${\pi}$-index within the set of trees and unicyclic graphs.

This study is to identify the characteristics of the growth and deveolpment, and to assess Obesity Index, BMI and Kaup Index of infants paticipated in a healthy breast-feeding contest. The subjects of this study were 94 breast- feeding infants, ages from 6 to 8 months. Their weight and height were measured and compared with Korean Standards. Their developmental state was tested by DDST(Denver Develop- mental Screening Test) standardized in Korea. The data were analyzed by using the SPSS-WIN 10.0. The result is as follows : 1. The weight of infants was more than Korean Standards, but the height was less. 2. There were statistically significant differences in Obesity Index, BMI and Kaup Index. Obese infants estimated by Obesity Index were about 10％, but by BMI and Kaup Index were 35.1％ and 27.7％. 3. Spearman's rhos of Obesity Index and Kaup Index, Obesity Index and BMI, and Kaup Index and BMI were individually 0.526, 0.528 and 0.753. In conclusion, BMI should be added to the criteria for assessing healthy breast-feeding infants.

To evaluate Helhimo's Anamnestic Dysfunction Index(AI), Helkimo's Clinical Dysfunction Index(HDI), and Friction's Craniomandibular Index(CMI) in Korean Young population, clinical examinations were performed in 207 dental college students who were healthy and had no evidence of the craniomandibular disorders. The obtained results were as follows; 1. The mean values of the Helkimo's Anamnestic Index(AI), Clinical Dysfunction Index(HDI), Fricton's Palpation Index(PI), Dysfunction Index(DI), and Craniomandibular Index(CMI) were 0.35, 0.71, 0.03, 0.05, and 0.04 in male subjects. 2. The mean values of the Helkimo's Anamnestic Index(AI), Clinical Dysfunction Index(HDI), Fricton's Palpation Index(PT), Dysfunction Index(DI), and Fricton's Craniomandibular Index(CMI) were 0.42, 0.72, 0.02, 0.04, and 0.03 in female subjects. 3. There was no statistically significant difference between male and female subjects in each parameter. 4.

This paper proposes a sound quality index to evaluate the vehicle interior noise. The index was developed using a correlation analysis of an objective measurement and a subjective evaluation data. First, the objective set of measurements was obtained at two specified driving conditions. One is from a wide-open test condition and the other is from a constant-speed test condition. At the same time, subjective evaluation was carried out using a score of ten scale where 17 test engineers participated in the experiment. The correlation analysis between the psycho-acoustic parameters derived from the objective measurement and the subjective evaluation was performed. The most critical factors at both test conditions were determined, and the corresponding equations for the sound quality were obtained from the multiple factor regression method. Finally, a comparative work between previous index and present index was performed to validate the effectiveness of the proposed index.

This paper presents a two-dimensional grouping index(2DG-index) for efficient processing of XML filtering queries. Recently, many index techniques have been suggested for the efficient processing of structural relationships among the elements in the XML database such as an ancestor- descendant and a parent-child relationship. However, these index techniques focus on simple path queries, and don't consider the path queries that include a condition value for filtering. The 2DG-index is an index structure that deals with the problem of clustering index entries in the twodimensional domain space that consists of a XML path identifier domain and a filtering data value domain. For performance evaluation, we have compared our proposed 2DG-index with the conventional one dimensional index structure such as the data grouping index (DG-index) and the path grouping index (PG-index). As the result of the performance evaluations, we have verified that our proposed 2DG-index can efficiently support the query processing in XML databases according to the query types.
