The left-associative grammar model (LAG) has been applied successfully to the morphologic and syntactic analysis of various european and asian languages. The algebraic definition of the LAG is very well suited for the application to natural language processing as it inherently obeys de Saussure's second law (de Saussure, 1913, p. 103) on the linear nature of language, which phrase-structure grammar (PSG) and categorial grammar (CG) do not. This paper describes the so-called Loom-LAGs (LLAG) -a specialization of LAGs for the analysis of natural language. Whereas the only means of language-independent abstraction in ordinary LAG is the principle of possible continuations, LLAGs introduce a set of more detailed language-independent generalizations that form the so-called loom of a Loom-LAG. Every LLAG uses the very smut loom and adds the language-specific information in the form of a declarative description of the language -much like an ancient mechanised Jacquard-loom would take a program-card providing the specific pattern for the cloth to be woven. The linguistic information is formulated declaratively in so-called syntax plans that describe the sequential structure of clauses and phrases. This approach introduces the explicit notion of phrases and sentence structure to LAG without violating de Saussure's second law iud without leaving the ground of the original algebraic definition of LAG, LLAGS can in fact be shown to be just a notational variant of LAG -but one that is much better suited for the manual development of syntax grammars for the robust analysis of free texts.

This study was performed to verify the craniofacial skeletal characteristics in anterior openbite group, in contrast to normal occlusion group, and also to find out, vertical factors which shows, correlate to the amount of anterior openbite. 21 individuals, including 10 males and 11 females, without orthodontic treatment history and anterior - posterior skeletal malrelationships, were selected and analyzed basic morphology and vertical factors, using standard lateral cephalogram. The obtained results as follows: 1. Comparison of anterior open-bite group with normal occlusion group using Moyers analysis. a) In basis morphologic analysis, Ba-SE-Me was lesser and Ba-SE-Mn. P. and Mn.P/A-B were greater in both sexes of anterior openbite group than in normal occlusion group. b) In angle measurements of vertical analysis, PMV/Pal. P. was lesser in male anterior openbite group and PMV/Occ. P. and PMV/Mn. P. were greater in both sexes of anterior openbite group than in normal occlusion group. c) In height ratio of vertical analysis, ATFH/PTFH and ALFH/ATFH were greater in both sexes of anterior openbite group than in normal occlusion group. 2. The amount of anterior openbite was correlated with PMV/Occ. P. and PMV/Mn. P.

Morphological characteristics of the asymmetric mandible in 135 adult male patients were investigated. Panoramic X-ray images were recorded. Age, ramus height, antegonial notch height, condylar height, coronoid process height, ramus body height and condylar neck angle were calculated and measured. Statistical analysis of unpaired two-tailed t-test and correlation coefficients was performed to find the morphologic differences between short ramus height side and the other. Condylar height and ramus body height in short ramus height side were smaller than those of the other side. Antegonial notch height, coronoid process height, condylar neck angle showed no differences. Condylar neck height was correlated with condylar neck angle.

Allergic contact dermatitis is a common skin disease resulting from specific immunologic sensitization to topically applied various allergen. The Purpose of this study was to investigate skin morphologic cahnges by light microscopic and scanning electron Microscope, changes of protein band by SDS-PAGE(SDS-polyacrylamide gel electrophoresis) in the skin effectiveness for beruty improvement of Geranium essential oil on skin troubles by surfactant. The results of the study are as follows, 1. From the observed result of FE-Scanning Electron Microscope, groups treated by Geranium essential oil in group treated Geranium essential oil during 1 week in surfactant treated group during 1 week, the group was repaired in irregularity surface of tissue by alleviate-keratinization of Geranium essential oil. 2. As a result of protein analysis the group treated on surfactant was rised protein upper range of 97,0004a11on by hyper-keratinization and group treated during 1 week by surfactant was decreased protein below range of 43,000dalton.

C-shaped canal configuration is very difficult to treat because that clues about preoperative canal anatomy cannot be ascertained from clinical crown morphology and limited information can be derived from the radiographic examination. This study was done to get more informations about the root and canal configuration of C-shaped root by 3-dimentionally reconstructing for the purpose of enhancing success rate of endodontic treatment. 30 mandibular molars with C-shaped root were selected. Teeth had been extracted from periodontal problems with sound crown and root portion, including teeth with caries lesion limited crown portion only.(omitted)

Vocal folds injury from vocal abuse is important topics of phonosurgery. Recent advances in diagnostic equipment, phonosurgery and speech analysis equipment have provided a lot of Information about fine movement of the vocal folds. However, predicting the reaction of the vocal folds to phonatory trauma remains difficult. The vocal folds need to withstand great vibratory and shearing stress and anchoring fibers of basement membrane Bone play a role in maintaining structural integrity of histologically different epidermis and superficial layer of lamina propria(cover of vocal folds). The purpose of this study is to demonstrate the changes of anchoring fibers in vocal polyp using transmission electron microscope. Various defects were observed : a irregular thickening of basement membrane, a near absence of normal anchoring fiber, a lot of electron dense material in superficial layer of lamina propria, a destruction of hemidesmosome and many vesicles carrying electron dense material In basal keratinocyte. These observations were suggestive of a hyperactivity of basal keratinocyte of vocal folds epithelium in response to vibratory stress.

Vehicle-logo recognition technology is very important in vehicle automatic recognition technique. The intended application is automatic recognition of vehicle type for secure access and traffic monitoring applications, a problem not hitherto considered at such a level of accuracy. Vehicle-logo recognition can improve Vehicle type recognition accuracy. So in this paper, introduces how to vehicle-logo recognition. First introduces the region of the license plate by algorithm and roughly located the region of car emblem based on the relationship of license plate and car emblem. Then located the car emblem with precision by the distance of Hausdorff. On the base, processing the region by morphologic, edge detection, analysis of connectivity and pick up the PCA character by lowing the dimension of the image and unifying the PCA character. At last the logo can be recognized using the algorithm of support vector machine. Experimental results show the effectiveness of the proposed method.

This study was investigated to evaluate the morphologic characteristics of deepbite tendency as multiple factors. The subjects consisted of 60 control subjects(male 25, female 35) and 137 deephite patients(68 male, 69 female). The deepbite group was composed of 4 subgroups(Class I 44, Class II div. 1 40, Class II div. 2 13, Class III 40). The mean age was 21.57 year for the control group 21 year for deepbite group lateral cephalograph in centric occlusion were taken, traced, and digitized for each subject. The statistically computerized analysis was carried out with SAS program. The results were as follows ; 1. In deepbite group, saddle angle is lesser than that of normal group. 2. The vertical dysplasia is prominent on anterior lower face and is closely related with mandibular form and inclination. 3. Without consideration of sagittal relationship, the dental factors such as curve of Spee, interincisal angle, U1 to upper lip length were prominent in the deepbite group. 4. Although there were individual variances in the perioral soft tissue profile, the lip presented more protruded pattern. 5. There was no significant difference in hyoid bone position and inclination between normal and deepbite group. 6. The multivariate discriminant analysis between normal and Class I deepbite group showed that curve of Spee, AB-MP angle, interincisal angle, articular agnle were critical in the determination of deepbite as multiple factors.
