There are several factors affecting the effectiveness of polymerization of the esthetic restorative materials. Among those factors, the initiator. camphoroquinone has the unique characteristic. of which the light sensitivity is very dependent on the wavelength of blue light. Camphoroquinone shows the most light absorption ability in the wavelength range of 470nm. So most of clinically used light curing systems adopt this phenomenon as their polymerization mechanism. The most popular way of light curing system is standard 40 second curing. But the problem of standard curing technique shows the rapid increase of resin viscosity followed by the acceleration of polymerization and the limited resin flow, resulted in reduction of the physicalproperty of restoration by retained stress. The object of this study was to verify the effects of narrow-banded wavelength on the microhardness of the esthetic restorative materials. a composite resin and a compomer, using filters which have peak wave length of 430nm, 450nm, 470nm, respectively. The results were as follows: 1. All the experimental groups showed lower hardness value than the control group. 2. In DyractAP, the hardness value by wavelength showed the same changing pattern on both upper and lower surfaces. 3. In DenFil, the hardness value by wavelength showed different changing pattern on upper and lower surfaces. 4. The hardness ratio showed similar pattern to the hardness variation of lower surface. but there was no significant difference between measurement in 10 minutes and 3 days later, besides the increase of hardness value.

The purpose of this study was to develop a basic bodice pattern and establish standards regrading to the size and grading of Korean misses' measurements in order to provide modern data for the ready-to-wear garment industry. 222 girls, aged from 18 to 27, were measured on 19 items of their structure. Mean, standard deviation, coefficient of variance, maximum, minimum, range and correlation coefficient between each items were analized. The analysis revealed the following significant results. The fundamental difference data of the bodice pattern and grading measurements between the year of 1975 and 1981 were as follow. (1) The measurements of bust and center back were used as a foundation to establish a standard size and grading. (2) Ranges of the bust circumference measurements were increased. Thus the sizes ere classfied into 5 groups. (3) The ease of bust circumference was increased due to the increasement of shoulder width. (4) The increase of the upper arm resulted to lower the bust line. (5) The shoulder slopes were higher than 1975. Therefore, the basic measurements of the shoulder slopes were reduced. (6) In spite of the front neck measurements were not changed, the back measurements were requied to increase. (7) the center front length became much shorter in the contrast with the increase of the center back length.

Shape description is an important and fundamental issue in content-based image retrieval (CBIR), and a number of shape description methods have been reported in the literature. For shape description, both global information and local contour variations play important roles. In this paper a new included-angular ternary pattern (IATP) based shape descriptor is proposed for shape image retrieval. For each point on the shape contour, IATP is derived from its neighbor points, and IATP has good properties for shape description. IATP is intrinsically invariant to rotation, translation and scaling. To enhance the description capability, multiscale IATP histogram is presented to describe both local and global information of shape. Then multiscale IATP histogram is combined with included-angular histogram for efficient shape retrieval. In the matching stage, cosine distance is used to measure shape features' similarity. Image retrieval experiments are conducted on the standard MPEG-7 shape database and Swedish leaf database. And the shape image retrieval performance of the proposed method is compared with other shape descriptors using the standard evaluation method. The experimental results of shape retrieval indicate that the proposed method reaches higher precision at the same recall value compared with other description method.

Black froak coat, white shirts, top hat and cane has been the symbol of gentlemen in 19th and early of 20th century. The pattern invented by Savile Row in London prevailed whole England. Such a pattern has been the standard form for two hundred years all over the word, although it was replaced with a functionalism which developed in Italy and America at the end of 20th century. The clothes of gentlemen was developed by several factors ; English people respect a tradition. The clothes was practical, since the weather in England was bad. The success of Industrial Revolution made England wealthy. Various special clothes in sports, for example, riding, criket, golf and tennis also contribute the modern gentlemen clothes with advance tailoring technique. The change of gentlemenship with social environment, from Regency dandy, Romantic gentlemen to Muscular Christianity, was studied. Idial gentlemenship and development its clothes which is now the standard of modern men's wear also studied.

With the increasing danger of personal information being exposed, a technique to protect personal information by identifying a non-user in case it is exposed. A study to construct a neural network recognizer for developing a economical and effective user protecting system. For this, time variables regarding user typing patterns from a pattern extraction device. With the variations in the standard deviation for the collected time variables, non-user patterns were generated. The recognition performance increased with the increase in the standard deviation and a higher recognition was achieved at 2.5. Also, five types of training data were generated and the recognition performance was examined as a function of the number of non-user patterns. With the increase in non-suer patterns, the recognition error quantified in the root mean square error (RMSE) was reduced. The smallest RMSE was obtained at the type 5 and 90 non-user patterns. In overall, the type 3 model yielded the highest recognition accuracy Particularly, a perfect recognition of 100% was achieved at 45 non-user patterns.

Most vehicles having automatic transmission system use fixed standard shift map to provide automatic transmission for driver. In this case, driver who operates vehicle may be complaint with the fixed transmission pattern being different from the driver's intention. In this paper, therefore, to infer the driver's intention module for learning the driver's intention with related input variables using soft computing method is proposed. After inference, the standard shift map will be shifted according to a certain parameter decided from the proposed module for providing proper shift pattern. The efficiency of the proposed module is evaluated by the data acquired from real time driving.

In this paper, an extension of the standard common spatial pattern (CSP) algorithm using the strong uncorrelated transform (SUT) is used in order to extract the features for an accurate classification of the left- and right-hand motor imagery tasks. The algorithm is designed to analyze the complex data, which can preserve the additional information of the relationship between the two electroencephalogram (EEG) data from distant channels. This is based on the fact that distant regions of the brain are spatially distributed spatially and related, as in a network. The real-world left- and right-hand motor imagery EEG data was acquired through the Physionet database and the support vector machine (SVM) was used as a classifier to test the proposed method. The results showed that extracting the features of the pair-wise channel data using the strong uncorrelated transform complex common spatial pattern (SUTCCSP) provides a higher classification rate compared to the standard CSP algorithm.
