Nowadays, Spoken Dialogue System is rapidly growing by investing a lot from researches as well as organizations. One of concrete evidences is that the appearance of commercial systems such as Siri, SVoice, DARPA, CLASSiC, GSearch etc. Moreover, Spoken Dialogue System is widely believed to be the future direction of software development. In Spoken Dialogue System, users interact to software by using their own voice instead of use their hands, keyboard, and mouse. This paper continuously presents our development of the Spoken Dialogue System on News. Particularly, we propose detailed design such as semantic concepts, semantic frames, slots, and so on for applying Hidden Vector State Model into our Spoken Dialogue System for Spoken Language Understanding.

In off-line process optimization, process parameters are controlled such that the process is robust against changes in equipment conditions and incoming materials. The off-line methods, however, are not effective when the changes are so large that process parameters need to be adjusted. On-line control can respond to such large changes, but process uniformity has not been controlled on-line due to the difficulties in modeling. This paper is aimed at developing a new on-line control methodology where the uniformity is controlled effectively. The process variability is categorized based on the physical considerations, and the process parameters are classi- fied considering their effects on the categorized process variabilities. On-line control is performed with the properly selected process parameters so that robustness may not be degraded. The developed methodology is applied to the single wafer plasma etching processes, which resulted in both higher within-a-wafer uniformity and compens- ation of the incoming material non-uniformity.

In constructing a credit scorecard, each characteristic variable is divided into a few attributes; subsequently, weights are assigned to those attributes in a process called coarse classification. While partitioning a characteristic variable into attributes, one should determine appropriate cutpoints for the partition. In this paper, we propose a cutpoint selection method via penalization. In addition, we compare the performances of the proposed method with classification spline machine (Koo et al., 2009) on both simulated and real credit data.

cDNA microarray-based comparative genomic hybridization(CGH) data includes low-intensity spots and thus a statistical strategy is needed to detect subtle differences between different cancer classes. In this study, genes displaying a high frequency of alteration in one of the different classes were selected among the pre-selected genes that show relatively large variations between genes compared to total variations. Utilizing copy-number changes of the selected genes, this study suggests a statistical approach to predict patients' classes with increased performance by pre-classifying patients with similar genetic alteration scores. Two-stage logistic regression model(TLRM) was suggested to pre-classify homogeneous patients and predict patients' classes for cancer prediction; a decision tree(DT) was combined with logistic regression on the set of informative genes. TLRM was constructed in cDNA microarray-based CGH data from the Cancer Metastasis Research Center(CMRC) at Yonsei University; it predicted the patients' clinical diagnoses with perfect matches (except for one patient among the high-risk and low-risk classified patients where the performance of predictions is critical due to the high sensitivity and specificity requirements for clinical treatments. Accuracy validated by leave-one-out cross-validation(LOOCV) was 83.3% while other classification methods of CART and DT performed as comparisons showed worse performances than TLRM.

This study was performed to obtain the basic data analyzing salt movement and desalinization effects, and two different desalinization experiments through leaching and rinsing were carried out, using samples of silt loam soil and silty clay loam soil collected in reclaimed tidelands. The relationships between the electrical conductivity of saturation extract and the electrical conductivity at various dilutions, and the correlations between electrical conductivity, total salt concentration, exchangeable sodium percentage and pH during the desalinization of reclaimed tidelands, were analyzed by the statistical method. The results obtained from this study were summarized as follows: 1.The sample soils used in this study were saline-sodic soils in accordance with the USDA classi- fication system of salt affected soils. 2.The electrical conductivity of saturation extract could be estimated conveniently, using the electrical conductivity of extract from various different soil-water suspensions. 3.The total salt concentration could be expressed in the electrical conductivity, but there was a little difference by soil textures. 4.The regression analysis showed that the relationship between the electrical conductivity of saturation extract and the exchangeable sodium percentage during the desalinization of reclaimed lands could be described by a linear regression equation. 5.The value of pH showed a tendency to increase according as the exchangeable sodium percentage decreased during the desalinization of reclaimed tidelands.

Movie is one of the most popular culture ac-tivities in modern society and the composite rt of science and art born in the 20th century. Movie became the great source of setting the fashion. Especially movie costume brought into relief and was accepted by the mass. As a movie stimulates imitation psychology and identification of the general public in fashion. The purpose of this study is to analyze the effects of the movie costume to a modern mass fashion. The times was defined the movies from the early Silent era to the modern Hollywood movie from the late of 1910 to 1990. The way of study were to analyze on the changes and roles of movie costume through documentary records and the influence of set-ting the fashion to the mass fashion and classi-fied it five times-silent era classics neo-classics new look and modern times. The summary of result is as follows, 1, Movie costume affected the dress and the fashion of women is Silent era. That fashion was accelerated by actors' costumes in the mode of 1920. 2. Holloywood movies in the Classics show the essence of the fashion movie costume played a role of a fashion leader and commanded the trend of mass fashion. 3. Practical style was shown because of the war in the Neo-classics. Movie industry was prosperous after the war. But the consequences of the movie costume to the mass fashion were more and more weaken 4. Couture designer's costume had an effect on the mass fashion in the early of New look. But it was behind the fashion for the rise of young fashion. 5. The tastes of the fashion were diversified in Modern times. So the movie fashion was not imitated or popular. The costume of "Pret-a-porter" was used in the movies in the 1980. Spectators became to wear the same style of the actors. The times fashion and movie interacted each other. Movie costume is playing a role of a fashion leader guiding the mass fashion.s fashion.

Because adolescents are much inflicted with the sense of obsession in endless competition with their feers the costume of the pop singers relieving this agony and anxiety is becoming the object of immitation more than that of any oother entertainer. In this perspective it was thought that it was very necessary to attempt to investigate what relationship sense of mental anxiety the costume singers recently have worn had with adolescents sense of anxiety. The anxiety questionnaire used by Chu Young-sook and Kim Jung-hui and the questionnaire drawn up as the result- of the pilot-test and the pre-test were used and the questionnaires drawn up by a total of 228 middle schoolgirls in seoul were used a sfinal data of annalysis. Of them the anxiety questionnaire was made up of 8 sub-scales such as classic·social·morbid·learning examination·school record·poverty·war and other to anxieties. in order to survey the overall content concerning the costume of the singers preferred by teenagers the other questionnaire presented three vaiables such as musicality fashionability and dance as the distinct characteristics of singers and hiphop style tidy style and sexy style of clothing as the style of clothing preferred of singers' clothing. The importance fashionability and imitability of clothing were investigated as variables in relation to singers' clothing behavior. The SPSS PC+ program was used as the analytic method of data which were tested by the frequency analysis Duncan's multiple anaylsis of variance t-test and so on. As a result of investigation middle schoolgirls having a high level of learning and examinatior anxieties preferred the singers excellent in musicality while middle schoolgirls having a lower level of classic anxiety preferred the singers excellent in fashionability and dance wearing the hiphop style of clothing. And it was shown that middle schoolgirls having a lower level of classic anxiety preferred the singers wearing the clothing of sexy style. In the light of these results it was shown that there was the correlation between anxiety and clothing preference. Accordingly it is thought that the purpose of this study was achieved to some exent.

This experiment was undertaken to study the relationship between dry weight of plant(DW) and yield components. varietal differences in seasonal production at each of three cutting. and to classiQ them into some patterns of seasonal production in tall fescue varieties. The varieties examined were Barvetia. Fuego, Demeter. Safe, Barcel. Forager, Johnstone. Enforcer and Stef. The results obtained were as follows : 1. The Fuego and Barcel with high number of tiller per plant(NT) which had more dry wieght of plant(DW) than those of varieties with low number of tillers per plant(NT) at each cutting. 2. The dry weight of plant(DW) in 1st cutting indicated positive significant correlation with the number of tillers per plant(NT) and dry weight of a tiller(WT). But there was only positive correlation between the number of tillers per plant(NT) and dry weight of plant(DW) in 2nd and 3rd cutting. 3. Mean relative yield of each cutting were 3 1 %. 29.7% and 39.3% in 1st. 2nd and 3rd cutting, respectively. 4. Tall fescue varieties could be classified into 3 different seasonal growth patterns according to their mode of relative yield at each cutting. Barvetia, Fuego, Johnstone. Enforcer and Stef belong to the group of ABA with high relative yield in 1st and 3rd cutting. Demeter, Safe and Forager belong to the group of CBA with relative yield increased linearly up to 3rd cutting. And, Barcel belong to the group of BAB with high relative yield in 2nd cutting.
