Geisha's gorgeous kimonos and grotesque make-up was the object of envy to Japanese women. There is a line in the movie like "Kimonos to the Geisha is the same as colors to the painter." Likewise, splendid patterns and colorful kimonos were an indispensible method or symbol for showing their artistic accomplishments. The purpose of this study is to investigate concept and origin of Geisha and their dress and decoration, analyze the dress of the people which appear in the movie, , arrange the expression of Geisha's dress as a movie costume, compare the difference of the dress by the career of Geisha and look back the disappearing aesthetic sense of Geisha. First, since Geisha appeared for the first time in Kyoto in 1751, it has become the world-wide representative of Japanese woman's images so that its existence oneself has become the tradition. Second, Geisha created fashion of various clothes, adornments, and hair styles as a creator of the popularity. Third, the strict regulation without exception is applied in Geisha's clothing, make-up, and motion tuned Samisen, Japanese traditional strings, and there is some difference in their hair style and dress by age of Maiko. Fourth, it is famous for unique make-up that Geisha makes up their faces, necks, and shoulders white, newly paints eyes, nose, lip line like drawing a picture in a pure white paper. Geishas put a little make-up as they have a higher position. Fifth, a heroin, Chiyo, shows clothing as a maid, an apprentice Geisha-Maiko- and a formal Geisha according to time flow. The length of kimono, textures, and hair decorations are longer, more splendid, and are more various as time goes. On the other hand, her make-up is lighter.

The prosthesis of the implant installed in inappropriate positions presents aesthetic and functional problems. If the implants are placed in the wrong position, re-implantation is often limited. There are surgical and non-surgical methods for resolving complications without re-implantation. The surgical costs, healing time, discomfort and unpredictability make this choice unpopular. On the other hand, a gingival mask has the advantage of solving complications quickly and simply. The patient was a 80-year-old male with palatally installed implant in maxillary anterior region and dissatisfied with his unesthetic philtrum and food impaction between the upper lip and the prosthesis. It was difficult to predict the prognosis of surgical operation, and the patient wanted treatment economically and physically burdenless because of his age and financial situation. Thus, the gingival mask was planned and the results were satisfactory.

Background : Maxillary hypoplasia refers to a deficiency in the growth of the maxilla commonly seen in patients with a repaired cleft palate. Those who develop maxillary hypoplasia can be offered a repositioning of the maxilla to a functional and esthetic position. Velopharyngeal dysfunction is one of the important problems affecting speech after maxillary advancement surgery. The aim of this study was to investigate the impact of maxillary advancement on repaired cleft palate patients without preoperative deterioration in speech compared with non-cleft palate patients. Methods : Eighteen patients underwent Le Fort I osteotomy between 2005 and 2011. One patient was excluded due to preoperative deterioration in speech. Eight repaired cleft palate patients belonged to group A, and 9 non-cleft palate patients belonged to group B. Speech assessments were performed preoperatively and postoperatively by using a speech screening protocol that consisted of a list of single words designed by Ok-Ran Jung. Wilcoxon signed rank test was used to determine if there were significant differences between the preoperative and postoperative outcomes in each group A and B. And Mann-Whitney U test was used to determine if there were significant differences in the change of score between groups A and B. Results : No patients had any noticeable change in speech production on perceptual assessment after maxillary advancement in our study. Furthermore, there were no significant differences between groups A and B. Conclusions : Repaired cleft palate patients without preoperative velopharyngeal dysfunction would not have greater risk of deterioration of velopharyngeal function after maxillary advancement compared to non-cleft palate patients.

The deformities of micrognathia and glossoptosis in the newborn are frequently associated with a cleft palate, which is known as Pierre Robin sequence. Upper airway obstruction is the most serious problem in these patients. Treatment of Pierre Robin sequence includes either positional or surgical intervention. Mild cases are often managed in the prone position. However, when the patient fails to thrive due to chronic upper airway obstruction, or severe respiratory distress ensures despite positional treatment, surgical intervention is mandatory to relieve the obstruction. We experienced three infants with Pierre Robin sequence who showed a symptom triad of micrognathia, glossoptosis, and cleft palate. Intermittent cyanosis, depression of the chest, respiratory difficulty and feeding problems were also observed. To relieve severe upper airway obstruction caused by micrognathia and glossoptosis, we simultaneously performed modified tongue lip adhesion (TLA) and a subperiosteal release of the floor of the mouth (SRFM). Respiratory and feeding difficulties were relieved, the tongue positioned anteriorly, body weight increased, and mandibular growth improved. Simultaneous TLA and SRFM may constitute a simple and reliable method for surgical treatment of airway obstruction in patients with Pierre Robin sequence.

Eruption disturbance is an abnormal state of eruption that occurs over a broad chronologic age range. There are many factors that influence eruption such as premature loss of primary teeth, supernumerary tooth, local disease, tongue, lip, mastication muscle and trauma. The purpose of this study was to determine the prevalence, patterns and tooth position that have eruption disturbance in children in Seoul, Korea. The subjects were 8,010 new patients who visited the department of Pediatric dentistry of Seoul National University Dental Hospital in 2004-2005. Clinical and radiographic records of the patients were reviewed by the primary investigator who is a pediatric dentist. Notable eruption disturbances included delayed eruption, early eruption and ectopic eruption and the prevalence of eruption disturbance was 8.79%.

The prosthodontic treatment of severely resorbed edentulous patients has been one of the frustrating areas due to extensive loss of tissues. The integrated neuromuscular balance among tongue, lip, and cheek is compromised. The retention, stability, and support are the three major factors to influence the clinical outcome. Fish described a denture as having three surface, with each surface playing an independent and important role in the over all fit, stability, and comfort of the denture. He recommended that the polished surface should be a series of inclines so that pressure from muscular activity will retain dentures. Within the denture space there is an area that has been termed the neutral zone. The neutral zone is that area in the mouth where, during function, the forces of the tongue pressing outward are neutralized by the forces of the cheeks and lips pressing inward. According to Jacobson and Krol, neuromuscular control interacts to provide retention and the relationship of polished surface of denture base to the surrounding muscular structure of orofacial capsule facilitates the stability and retention. This neutral zone concept has been demonstrated with various modification by a number of authors. The theory used to develop the denture base contours is based on the belief that the muscle should functionally mold not only the border but the entire polished surface. Lott and Walsh reported the clinical success on complete mandibular dentures with application of neutral zone concept. A number of studies demonstrated that denture stability and retention are more dependent on correct position of the teeth and correct contour of external surfaces of the denture in a severely resorbed alveolar ridge. This article presents a prosthodontic approach to treatment of a edentulous patient using neutral zone technique to improve the retention and stability of the prosthesis.

Background: The chin shape and position is important in determining the general shape of the face, and augmentation genioplasty is performed alone or in combination with other aesthetic procedures. However, augmentation genioplasty using osteotomy is an invasive and complex procedure with the potential to damage mentalis muscle and mental nerve, to affect chin growth, and prolonged recovery. Our aim was to present our experience with a modified augmentation genioplasty procedure for hypoplastic chins using a Gore-Tex implant. Methods: Two vertical slit incisions were made at the canine level to create a supra-periosteal pocket between the incisions, preserving the periosteum and mentalis muscle. Minimal sub-periosteal dissection was performed lateral to the incisions along the mandibular border. The both wings of implant were inserted under the periosteum to achieve a stable dual plane implantation. Results: In total, 47 patients underwent dual plane chin augmentation using a Gore- Tex implant between January 2008 and May 2013. The mean age at operation was 25.77 years (range, 15-55 years). There were 3 cases of infection; one patient was treated with antibiotics, the others underwent implant removal. Additionally, two patients complained of postoperative parasthesia that spontaneously improved without any additional treatment. Most patients were satisfied with the postoperative outcomes, and no chin growth problems were observed among the younger patients. Conclusion: Dual plane Gore-Tex chin augmentation is a minimally-invasive operation that is simple and safe. All implants yielded satisfactory results with no significant complications such as mental nerve injury, lower lip incompetence, or chin growth limitation.

Orthodontic treatment in conjunction with second-molar extraction has been a controversial issue among orthodontists over many decades. The aim of this study was to investigate the treatment effects of upper second molar extraction cases. The sample included 19 upper second molar extraction orthodontic cases(ten Angle's Class I's and nine Class II's, average age=13Y 6M) cared at Kyung-Hee University Department of Orthodontics. Lateral cephalometric radiographs were taken before and immediately after treatment. Seventy-nine points were digitized on each cephalogram and 38 cephalometric parameters were computed comprising 22 angular measurements, 13 linear measurements, and 3 facial proportions. The data obtained from each malocclusion group were analyzed by paired t-test. The statistical results disclosed that there was no significant change in skeletal pattern after treatment except for that accountable by growth while there was statistically significant change in dentoalveolar and soft tissue patterns. There were no significant changes in Bjork sum, posterior facial height /anterior facial height and lower anterior facial height /anterior facial height. No significant changes in anteroposterior position of maxilla and palatal plane were manifested. Although facial axis and lower facial height was slightly increased and the mandible was rotated backward and downward, there was no remarkable change in the mandibular plane. There were statistically significant changes in distal movement of upper first molar, molar key correction and overjet reduction while there was no change in the occlusal plane. The upper lip was slightly retracted simultaneously with slight increase in nasolabial angle. These results signify that distalization of upper dentition with the second molar extraction does change occlusal relationship without gross modifications in the craniofacial skeletal configurationson. Henceforth the second molar extracted would be recommended to treat severe anterior crowding and protrusion with minor skeletal discrepancy.

In order to use an enzyme industrially, it is necessary to increase the activity of the enzyme and optimize the reaction characteristics through molecular evolution techniques. We used the error-prone PCR method to improve the reaction characteristics of LipCA lipase discovered in Antarctic Croceibacter atlanticus. Recombinant Escherichia coli colonies showing large halo zones were selected in tributyrin-containing medium. The lipase activity of one mutant strain (M3-1) was significantly increased, compared to the wild-type (WT) strain. M3-1 strain produced about three times more lipase enzyme than did WT strain. After confirming the nucleotide sequence of the M3-1 gene to be different from that of the WT gene by four bases (73, 381, 756, and 822), the secondary structures of WT and M3-1 mRNA were predicted and compared by RNAfold web program. Compared to the mean free energy (MFE) of WT mRNA, that of M3-1 mRNA was lowered by 4.4 kcal/mol, and the MFE value was significantly lowered by mutations of bases 73 and 756. Site-directed mutagenesis was performed to find out which of the four base mutations actually affected the enzyme expression level. Among them, one mutant enzyme production decreased as WT enzyme production when the base 73 was changed (T→ C). These results show that one base change at position 73 can significantly affect protein expression level, and demonstrate that changing the mRNA sequence can increase the stability of mRNA, and can increase the production of foreign protein in E. coli.
