The walls of guard cells have many different specialized features. Guard cells are present in leaves of bryophytes, ferns and almost all of the vascular plants. Guard cells show considerable morphological diversities. It is understood that the stomata show two types in terms of morphological characterizations of guard cells. The first type is only found in a few monocots including Poaceae and Cyperaceae. In rice and corn, guard cells have the morphological characteristics of dumbbell shape. The morphological characteristics of dumbbell shape always have subsidiary cells. The other type is found in every dicots and many monocots and they are kidney-shaped guard cells. The plants of kidney-shaped guard cells rarely have subsidiary cells except Commelina communis L. Therefore, it could be concluded that two types of the morphological characteristics of guard cells cannot divide according to monocots or dicots. Every plants in which stomatal characteristic features were all different, most of them belong to kidney-shaped guard cells. However in case of Sedum sarmentosum, guard cells were shown to be long and narrow lips type. In Tradescantia virginiana, the shape of guard cells could be called perfectly to half-moon type. Therefore, it could be concluded that kidney-shaped types are all different in some way, but dumbbell-shaped types are almost constant.

A problem that affects children's dentitions is the harmful habit which is difficult to treat. Harmful habits for children are such as abnormal swallowing patterns, low/forward tongue rest posture problem, habitual open-lips resting posture, habitual mouth-breathing, excessive digital sucking habit and tongue thrusting. Tongue thrusting habits cause a bit of cranio-facial skeletal changes and a great deal of dental malocclusion such as anterior open bite. Anterior open bite causes masticatory, speech, and esthetic problems in the growing children and difficulties in diagnosis, treatment, and the prediction of its prognosis. The treatments of such abnormal behaviors involve orofacial myofunctional therapy and using of habit breaking appliance. The prognosis is not determined by the presence of severity of oral habit but the skeletal tendency of the patient. Usage of tongue crib resulted in not only the discontinuance of the habit but also improvement in overbite and overbite. This study showed that relatively successful results could be generated by using removable tongue crib and myofunctional therapy in the case of openbite related to tongue thrusting habit.

The incisors function as instruments for biting and cutting food during mastication. They also support the lips and face and maintain vertical dimension. In addition, they contribute to overall normal arch appearance. They play important role during the articulation of speech and assist in guiding jaw closure. Extraction and space maintenance are the most common treatment for a tooth with poor prognosis. However, in the mixed dentition, extraction of the upper permanent incisors results in many complications, such as resorption of alveolar bone, poor esthetics, pronunciation, and mastication. Considering these various roles of incisors in oral cavity, approach for traumatized incisors, even the ones with poor prognosis, should be considered first prior to simple extraction. The dentist must take into account the age of the patient, growth potential, occlusion, oral hygiene status, economic status and motivation towards dental health in addition to patient compliance. In this case, although the prognosis was predicted to be unfavorable due to short root and mobility, we could save the central incisor using conservative treatment, reposition by orthodontic appliance instead of extraction.

The pathogenicity and infection route of the Scuticociliate, Philasterdies dicentrarchi, were investigated with the 3 and 5 cm-group of juvenile flounders, Paralichthys olivaceus. The infection rates of 3 cm-group were 40% four days post infection (D.P.I.) and increased to be 90.1% 24 D.P.I., whereas those of 5 cm-group were 20% 8 D.P.I., 42% 16 D.P.I., and 81% 24 D.P.I. The results showed there were several infection routes to internal organs Olive flounder. The first route was started with the infection at the soft part of caudal fin and later reached at fin ray and muscle tissue; the second one was started from lips and mouth tissue of upper jaw and later the pathogen could be observed at either muscle tissue or eyeball and brain; the third one was begun at caudal fin and later the pathogen reached at brain tissu'e through spiral cord; the fourth one was started with the infections at abdominal cavity and anus. P. dicentrarchi infected to brain tissue was first observed 14 D.P.I in 3 cm-group and 20 D.P.I. in 5 cm-group of the juvenile flounder. This indicated that the brain infection of P. dicentrarchi might occur faster in small-sized flounder than large-sized one.

A 5-year-old Rottweiler neutered female dog was presented with signs of mandibular and popliteal lymphadenopathy, erosion in mucocutaneous junction of muzzle and lips, multiple papules and nodules in right rear limb and neck, and alopecia in right thorax. There was no further clinical sign except anorexia, sporadic fever and ocular hyperemia. She hadn't shown any response to carprofen prescribed by local veterinarian. Hematological abnormalities included mild anemia and severe lymphocytosis. On serum biochemical profile, only elevated AST level was noticed. On cytological examination, there was an evidence of mild bacterial infection which seemed to occur secondarily. Three sites were biopsied that included muzzle, upper lip and right thoracic region. Histopathologically, multifocal confluent pyogranulomatous dermatitis, scattered granulomatous inflammation in subcutis and severe septal panniculitis were observed. Special stainings(Gram, Acid-fast, PAS, Giemsa) were performed to reveal that a dog was negative for any organism. Finally, sterile pyogranuloma/granuloma syndrome (SPGS) was diagnosed. The treatment was initiated with predinsolone and enrofloxacin. The condition was successfully resolved after 4 weeks of treatment. This good response suggests that SPGS may be immune-mediated disease of its pathogenesis and this drug combination may be a viable therapeutic option for dogs suffering from SPGS. Also, this article reports a case of SPGS in Rottweiller for the first time.

Four volumes of the script of the Avatamska Sutra written with golden paste on dark blue papers manufactured in Koryo Dynasty which are collected or deposited in every museum of Japan show specific features on their cover paintings. In general 3 or 4 lotus flowers are wound by arabesque patterns in zigzag on the cover paintings of Koryo scripts, whereas 10 lotus flowers painted with golden paste on the 4 volumes of these scripts are same in their style. Though there is no prayer sentences in 4 volumes of the script, it is possible to know that they should belong to a set of 80 Avatamska Sutra by the results of above studies. In this study the contents of Byunsangwha of the script of 4 volumes of the Avatamska Sutra were discussed at first and their manufactured era should be postulated by the results of style analysis of cover paintings and Byunsangwha. First thing that saint hair of Buddha was painted with cobalt color is same as that of Byunsangwha of Munsuchoisangsungmusenggebueob prayed in Tejeong 3rd year, king Chungsuk 13th year(AD 1326). Second thing that the beads in topknot of saint hair and lips were painted completely with pink color, and ears, face outline as well as bosom outline disclosed through monk's cloth were also painted with pink color, furthermore the last thing is that Buddha's face was coated with golden paste. All of these things are same as shown in the characteristics of Byunsangwha of the scripts of Kanezawa Daishoji, Matsue Tenrinji and Haga Tera collection in Japan. However, since the cloud pattern style of Byunsangwha of the script is similar to that of the Byunsangwha manufactured in reinstatement era of king Chungsuk, it is possible to say that these 4 volumes of script should be manufactured in the reinstatement era of king Chungsuk.

1. Objective The object of this study was to understand the clinical characteristics of the Taeeumin Symptomatic Pattem. 2. Methods The patients visiting the department of Sasang Constitution of Traditional Korean Medicine clinic from June to November of 2008 were used in this study. Those who showed a favorable turn after over ten days of medication and who showed up for at least two follow-up sessions were chosen among first-time visitors. Of these, 75 patients identified and verified to be of the TE type were chosen for the study sample. The Taeeumin were verified into two groups according to clinical symptoms into Exterior Cold Disease and Interior Heat Disease groups, of which the Interior Heat Disease group was further subdivided into the Galgeun-medicament group and the Cheongshimyeonja-tang group, based on questionnaire results. The Exterior Cold Disease group was set as the control group in order to contrast and compare it with the study group, the Interior Heat Disease group. 3. Results and Conclusions The questionnaire items shown to differentiate the Exterior Cold Symptomatic Patterm and the Interior Heat Symptomaic Pattern (indicating Heat-affceted Liver Symptomatic Pattern) were related to "dryness of stool," "dark urine colorm," "dryness of nose," and "dryness of lips." The items shown to differentiate the Galgeun-medicament group and the Cheongshimyeonja-tang group (of the Dry - Heat Symptomatic Pattern) were related to "nausea," "stifling sensations and palptation," "disturbed sleep," and "dizziness." Therefore, the sleep pattern, palpitation, dizziness, and nausea can be said to be indicators of the Interior Heat Symptomatic Pattern, and Dry-Heat symptoms are better distinctions between the Chongshimyeonja-tang group and the Galgeun-medicament group than Heat-affected Liver symptoms.

In this paper, we propose a speech animation synthesis specialized in Korean through a rule-based co-articulation model. Speech animation has been widely used in the cultural industry, such as movies, animations, and games that require natural and realistic motion. Because the technique for audio driven speech animation has been mainly developed for English, however, the animation results for domestic content are often visually very unnatural. For example, dubbing of a voice actor is played with no mouth motion at all or with an unsynchronized looping of simple mouth shapes at best. Although there are language-independent speech animation models, which are not specialized in Korean, they are yet to ensure the quality to be utilized in a domestic content production. Therefore, we propose a natural speech animation synthesis method that reflects the linguistic characteristics of Korean driven by an input audio and text. Reflecting the features that vowels mostly determine the mouth shape in Korean, a coarticulation model separating lips and the tongue has been defined to solve the previous problem of lip distortion and occasional missing of some phoneme characteristics. Our model also reflects the differences in prosodic features for improved dynamics in speech animation. Through user studies, we verify that the proposed model can synthesize natural speech animation.

The esthetic factor for the esthetic prosthesis were studied on 300 persons. The praaticipants were 150 students registered under the Deparment of Dental Laboratoy Technology, Jisan Junior College at the present day of June, 1995 and their mothers. The results were as follows; 1. The number of persons with 28 teeth in their oralcatity was highest(P<0.01). They complained that they have only 28 teeth bacaues of the loss(deficiency) fo teeth due to their impacted teeth and dental caries. 2. The presons with feelings of dissatisfaction were large in number(P<0.01). They were dissatisfied with an abnormal tooth form(33.5%), tooth position(31.7%), tooth color(31.1%), and tooth size(3.7%) in order(P<0.01). 3. In their facial form, the most numerous were men with square form and women with ovoid form(P<0.01). Among the whloe number fo facial forms it appeared to decresae in the order of ovoied(41.8%), square(32.7%), square+tapered(20.5%), and tapered form(5%)(P<0.01). In a profile form, the most numerous were men with A form and women with B. Among the whole participants the most numerous were persons with B form and persons with A and C form were next in oder of numbers(P<0.01). 4. In discoloration of teeth, the most numerous were persons who have no discoloration. 5. In the esthetic recovery of anterior prosthesis the color matching of proximal teeth was not correct, but the outline of proximal teeth was to be reproduced correctly. 6. In the diastema of teeth, the number of persons who have no diastema was higher than that of persons who have a disatema(P<0.01) Among the persons who have diastema the most numerous were persons who have a diastema, and next were 2, 4, 3 and 5 diastemas in order. 7. In a meeting point of the midline of the body and the tooth the number of person hanving a meeting point was higher than that of persons who did not fit each other(P<0.01). The bias direction of midline teeth appeared to be affected by chewing direction, prosthesis location, and posterior location. 8. The length and width of teeth in the tooth size were suitable(P<0.01). The number of persons who have central teeth longer than lateral teeth was high(P<0.0). 9. In the results of smile analysis, the line form connected with incisal edge of upper canine were parallel(P<0.01). When smile the location fo upper lips should be in accord with the central area of teeth(P<0.01) and lower lip should be atteched to the edge of anterior teeth in order to be esthetic. 10. Among the number of upper teeth we can see the most numerous were 8 teeth and next were 10, 6 and 12 in order.

This paper is presented to study simplification of face image using cubic spline interpolation for a business card with 2D barcode. People often forget business card's owner because business cards don't be included a face picture generally. To solve such problem, many applications have be developed through mobile devices, Internet and so on. But they couldn't caught up with value of existing business card mad by paper. Hence, some methods which can put information on business card using 1D or 2D barcode had suggested. but they couldn't include information like face image or company logo image which have too much data. Therefore, we study the simplification method of face image to encode from a face image to 2D barcode. The simplification method using spline curves defined by feature points which we dotted on face, ears, hair, eyebrows, nose, lips, neck, etc.. on a face area. for experiment, we see real face image and simplified face image made by proposed method after we automatically extract face watch through camera. In experimental results, data of simplified face image was reduced as small as it can be expressed by 2D barcode, and confirmed that it can effectively express features.
