  • This study aims to show why and how the shift in the point of articulation for Korean consonants occurs with an increase of their tensity. From an EPG study on the point of articulation for Korean alveolar stops, fricatives and velar stops, it was concluded that the shift in the point of articulation occurs because the increase in the tensity of Korean consonants requires more contact area with the roof of mouth by the tongue, and that the direction of the shift depends on the surface shape of tongue for the plain consonant.

  • This study attempted to reveal the physiologic etiology or related factors associated with speech processing by comparing the compensation ability in speech motor control in children with and without articulation disorders. Subjects were 35 children with articulation disorder and 35 children without articulation disorder whose age ranged from 5 to 6 years. They were asked to rapidly repeat /$p^ha$/, /$t^ha$/, /$k^ha$/, /$p^hat^hak^ha$/ diadochokinetic movement while mandible was free and mandible was stabilized with bite block. The results showed that children with articulation disorder revealed significantly greater difference in elapsed time for diadochokinetic movement between mandible free and stabilized state compared to the without articulation disorder group. But the correlation between the percentage of consonants correct and the compensation ability in speech motor control in the articulation disorder group was irrelevant. These results point out to the fact that children with articulation disorder have poor compensation ability in speech motor control compared to the children without articulation disorder. On the other hand, the poor ability does not have any relation with the severity of articulation disorder. These results suggest either general or individual characteristics of children with articulation disorder.

  • Based on the geometric representation an efficient al-gorithm is designed to find all articulation points of a permutation graph. The proposed algorithm takes only O(n log n) time and O(n) space where n represents the number of vertices. The proposed se-quential algorithm can easily be implemented in parallel which takes O(log n) time and O(n) processors on an EREW PRAM. These are the first known algorithms for the problem on this class of graph.

  • Background and Objectives : The operation Double Opposing Z-Plasty, has been used for improving VPI function in the submucous cleft palate. However, few reports on the effects of the speech change were presented. The purpose of this study is to compare the difference of nasality and nasalance, parents satisfaction between before and after this operation and to consider how much improvement in speech. Materials and Methods : Ten submucous cleft palate children who underwent double opposing Z-plasty were analyzed. We retrospectively studied nasalance, auditory perception (nasality) with hypernasality, patients satisfaction, speech evaluation by using charts review, video tape, telephone interview. Results : In 8 patients of 10 submucous cleft palate, hypernasality reduced and speech intelligibility was higher and mean 0.35 point was increased in the velum length after operation. After operation, nasality was improved (2.0 point) and level of nasal emission decreased. Regarding satisfaction of this operation, scale was mean 2.8 (5 point-scale) : 8 parents were satisfied in the resonance, 3 parents were satisfied articulation. The reason of dissatisfaction was mostly compensatory articulation. Conclusion : To improve of speech in the submucous cleft palate, speech therapy afterthis operation as well as successful surgery should be considered.

  • We define a SG(String Graph) and an ASG(Alive String Graph) to the purpose to do static analysis. For a life and death judgment, we apply the rule to the situation which the stone is included and not included. We define the rules that are SR(String Reduction), ER(Empty Reduction), ET(Edge Transform), and CG(Circular Graph), when the stone is not included. We define the rules that are DESR(Dead Enemy Strings Reduction) and SCSR(Same Color String Reduction), when the stone is included. We evaluate a SG that it is an ASG or not by using rules. And we use APC(Articulation Point Check) nile according to number of articulation points lot a life and death judgment. The performance of our method has been tested on the problem set IGS_31_counted form the Computer Go Test Collection. The test set contains 11,191 Points and 1,123 Strings. We obtain 92.5% accuracy of Points and 95.7% accuracy of Strings.

  • Sensitivity has become more important in relation to design in the changing social environment and atmosphere. In the West, the concept of aesthetics has long been established but in the East, only in the seventeenth and eighteenth century China did the discussion begin. In Korea, where the first scholarly discussion on aesthetics began around 1929, more and more rigorous and theoretical discussions are emerging now. Korean beauty consists of the beauty of no-artfulness and the beauty of natural artfulness. Japanese beauty consists of the beauty of half-articulation and the beauty of articulation. While both Korea and Japan base their sense of beauty on nature, Korea emphasizes nature as it is while Japan values artful decorative elements. Especially in modern Korean fashion, the characteristic Korean aesthetics of un-artfulness appears in various expressive techniques such as the movement with natural gathering, the use of natural materials like cotton, the harmonization of black and white, and a simplified silhouette. In Japanese fashion, one can see techniques such as: the beauty of half-articulation expressed through the ambiguity of shapes, colors, and genders or simplicity and paucity using straight lines, the beauty of articulation expressed with bright flower prints and ornaments, accessories of Obi and feathers and the transformed silhouette.

  • Articulation type container cranes are the boom forms an inverted L shape when raise. The inner boom section is nearly vertical when raise and the outer boom section is nearly horizontal. Articulation type container cranes were developed as a lower height crane to meet aircraft clearance requirements. Because the height of an Articulation type container crane is about 70m, the crane is subjected to the effect of Wind load. Therefore, the problem on the effect of Wind load is receiving carefully study. The researches for the effect of wind load on the structural stability of a conventional container crane are conducted. In this study, we carried out the investigation for an articulation type container crane. When a wind load is applied to a container crane, we analyzed the reaction force distribution at each supporting point of a crane with respect to a wind load direction and the effect of the change of the machinery house location on the structural stability rf a crane by carrying out Finite Element Analysis.
