  • This paper proposed the face recognition method which can be effectively applied to the robot's vision system. The proposed algorithm is recognition using hue extraction and feature point. hue extraction was using difference of skin color, pupil color, lips color. Features information were extraction from eye, nose and mouth using feature parameters of the difference between the feature point, distance ratio, angle, area. Feature parameters fuzzified data with the data generated by membership function, then evaluate the degree of similarity was the face recognition. The result of experiment are conducted with frontal color images of face as input images the received recognition rate of 96%.

  • In the Edo period speaking of hair culture, common women wore decorative pigtail ribbons on the right, and twisted from side to side their tressed hair in such a manner as ungeunmeori and traemeori. Instead of gachae, common women used gogae made of their own hair, ungeunmeori on forehead, or jjokjinmeori at the back of head. During the Edo period, people women naturally exposed their necklines as a way of exposing their faces in the aesthetically ceremonial act of wearing make-up. As for lipsticks, they rouged extracts from red petals of safflowers mainly on their lips, and sometimes on their cheeks by blending this with white powder. Samurai families disliked women who wore thick lip makeup. In the latter period, women painted their necklines or foreheads black, applied a small amount of rouge on their cheeks thinly or thickly, and colored a reddish color into their fingernails by using petals and leaves of balsam flowers. Despite the chronological and spatial proximity of the King Jeongjo period and the Edo period, it was found that there were no similarities between two countries' cosmetic cultures. Moreover, it was discovered that current TV dramas were being produced, even not based on historical evidence in the Jeongjo period.

  • Reconstruction of the lower lip requires consideration of several factors. There should be retained sensation, maintenance of oral sphincter function, and a large enough opening for the mouth. In addition, it is important to achieve an aesthetically acceptable appearance. Webster's modification of Bernard operation is one of good methods which satisfy above mentioned goals. The purpose of this article is to present the results and review the perioperative problems after reconstruction of the lower lip by this operation. We reviewed seven patients after surgical reconstruction by the same method between January of 1996 and December of 2003. Five patients were male and two were female. The mean follow-up period was 15 months. We obtained functionally and cosmetically acceptable appearance after reconstruction. Most of the reconstructed lower lips were large enough for full mouth opening, but one patient required additional commissuroplasty, and one other patient was treated with wound revision for dehiscence resulting from protrusion of mandibular lateral incisor tooth. All other patients accepted their facial appearance. In conclusion, careful planning and consideration for dental problems and proper closure tension may ensure satisfactory outcome & lower lip competence, when using this modified operative method for lower lip reconstruction.

  • Hemangiomas are the most common benign tumors or tumor-like malformations of blood vessels or blood filled cavernous spaces. Hemangiomas of the oral cavity represents 14% of all hemangiomas. Most hemangiomas are detected by one year of age and most commonly occurred in the lips, tongue, buccal mucosa and palate. But hemangiomas are sometimes reported in adults. We report one case of extensive hemangioma of the tongue in adult. Our case is a 48-year-old male who presented with a hemangioma occupying entirely two-third of the tongue. Treating those lesions pose a challenge to the surgeon. This paper discusses one case of extensive tongue hemangiomas treated with alcoholic sclerotherapy with satisfactory results supporting this particular approach in the management of these lesion.

  • This work aims to study the effect of stiffener ties in the behavior of intermediate length open section Cold-Formed Steel (CFS) Columns under axial compression. A comparative study on the behaviour and strength of Cold Formed Steel Columns by changing the direction of projection of lips (i.e., inwards or outwards) are also done. In this work two types of sections were considered Type-I section with lip projecting outwards (hat) and Type-II section with lip projecting inwards (channel). The length of the columns is predicted by performing elastic buckling analysis using CUFSM software. The theoretical analysis is performed using DSM - S100;2007, AS/NZ: 4600-2005 and IS: 801-1975. The compression tests are carried out in a 400 kN loading frame with hinged-hinged end condition. The non-linear numerical analysis is performed using Finite Element software ANSYS 12.0 to simulate the experimental results. Extensive parametric study is carried out by varying the width and spacing of the stiffener ties. The results are compared; the effects of stiffener ties on behaviour and load carrying capacity on both types of columns are discussed.

  • This study describes a modified preemphasis formula, what we call energy-dependent preemphasis(EDP). This uses the normalized short-term energy of speech signal, with the assumption that the source characteristics of the glottal pulses and the radiation characteristics of the lips are approximately proportional to the energy of speech signal. Using this method, speech analyses, such as AR spectrum estimation, formant detection, are performed for nonstationary starting parts of 5 Korean single vowels. The results are compared with the conventional two preemphasis methods. We found that the proposed preemphasis gave enhanced spectral shapes and more accurate formant frequencies and avoided overlapping phenomenon of adjacent two formants.

  • In this paper, we set 6 interesting points around lips. Analyzed and characterized is the distance change of these 6 interesting points when people pronounces 5 vowels of Korean language. 450 data are gathered and analyzed. Based on this analysis, the system is constructed and the recognition experiments are performed. In this system, we used the camera connected to computer to measure the distance vector between 6 interesting points. In the experiment, 80 normal persons were sampled. The observational error between samples was corrected using normalization method. We analyzed with 30 persons and experimented with 50 persons. We constructed three recognition systems and of those the neural net system gave the best recognition result of 87.44 %.

  • Acrobeles ciliatus (von Linstow, 1877) and Plectus parietinus (Bastian, 1865) are newly collected from Korea. Acrobeles is similar to those nematode belongs to Rhabditidae and Panagrolaimidae by having terminal bulb without medium bulb but different by having complex, vines shaped labial attachment. A. ciliatus differed from other Acrobeles species by lateral fields with two incisures, primary axils U-shaped, and secondary axils V-shaped. Head region set off with the neck, three high labial probolae present, each having 5 tines at inner margins and 5-7 at outer margins, and two elongate apical tines. Also, it differs from the longer female body. Plectus parietinus is distinguished from all other species of Plectus by the prominent hypodermal glands, the relatively small amphid, the distinct and well set-off lips and by the subdorsal distal caudal seta on the left side of the tail. Stoma without stylet. Oesophagus about 1/4 of total body length with terminal bulb. Anus ca. $100{\mu}m$ from posterior extremity. Vulva is at middle of body. Have spinneret on tail tip.

  • In this study we propose to use a facial motion capture technique to track facial motions and expressions effectively by using the stereo vision module, which has two CMOS IMAGE SENSORS. In the proposed tracking algorithm, a center point tracking technique and correlation tracking technique, based on neural networks, were used. Experimental results show that the two tracking techniques using stereo vision motion capture are able to track general face expressions at a 95.6% and 99.6% success rate, for 15 frames and 30 frames, respectively. However, the tracking success rates(82.7%,99.1%) of the center point tracking technique was far higher than those(78.7%,92.7%) of the correlation tracking technique, when lips trembled.
