  • The Lambda Networking is emerging to provide the high bandwidth stably for advanced applications such as a large file transfer in High Energy Physics and an Uncompressed HDTV streaming. The User Controlled LightPath(UCLP) is a software to facilitate the Lambda Networking. The UCLP is scalable as using Web Services to define and manage network resources. In this paper, we describe how we deployed the UCLP into KREONet2 and GLORIAD-KR. We also present that the original UCLP creates only a link-level APN due to a SONET technology. As employing a Virtual LAN (VLAN) of the layer2 technology in the UCLP, we can efficiently create a network-level APN.

  • Objective: To determine whether there is any difference between the cleft and non-cleft sides of the mandible in unilateral cleft lip and palate (UCLP) patients, or the right and left sides in control patients; and to determine if there is any difference between the mandibular asymmetry of UCLP patients and that of control patients. Methods: We examined cone-beam computed tomography (CBCT) scans of 15 patients with UCLP and 15 age- and gender-matched control patients. We evaluated 8 linear, 3 surface, and 3 volumetric measurements and compared the cleft/non-cleft sides of UCLP patients and the right/left sides of controls. Results: There were no statistically significant gender differences in any linear, surface, or volumetric measurement. The single significant side-to-side difference in UCLP patients was a longer coronoid unit on the cleft side than on the non-cleft side ($p$ = 0.046). Body volume was significantly lower in the UCLP group than in the control group ($p$ = 0.008). Conclusions: In general, UCLP patients have symmetrical mandibles, although the coronoid unit length is significantly longer on the cleft side than on the non-cleft side. UCLP patients and controls differed only in body volume.

  • A roentgeno cephalometric comparative study was undertaken to reveal significant differences of craniofacial morphology and growth between unilateral cleft lip and palate and normal individuals. The material for this study consisted 32 subjects with repaired unilateral cleft lip and palate (27 male, 5 female) and 44 normal subjects (22 male, 22 female). The analysis was performed by Coben's method and the measurements were compared by Student's t-test. The following conclusions were obtained. 1. In the UCLP subjects there is definite decrease in midfacial growth, so they showed concave profile. 2. The ramus inclination angle and AR-GO of UCLP subjects are larger than normal subjects. 3. The craniofacial height of UCLP subjects is smaller than normal subjects, especially in midface. 4. The lower part of craniofacial height of UCLP subjects is larger than normal subjects.

  • Objective: The objectives of this study were to evaluate linear and volumetric alveolar changes induced by nasoalveolar molding (NAM) in infants with complete unilateral cleft lip and palate (UCLP) and compare the maxillary dimensions after NAM with the normal dimensions in infants without clefts. Methods: A total of 26 infants with UCLP treated by NAM (mean age before and after NAM: $14.20{\pm}8.09days$ and $118.16{\pm}10.06days$, respectively) comprised the treatment group, while 26 infants without clefts (mean age: $115.81{\pm}8.71days$) comprised the control group. Changes in the maxillary dimensions following NAM were measured on three-dimensional models using Mimics software, version 17.0. Results: During NAM, there was a decrease in the cleft widths, maxillary arch depths, and rotation of the greater segment. While the anterior alveolar arch width exhibited a significant decrease, the posterior arch width was mostly maintained. There were no changes in the anterior vertical deviations of the alveolar segments. The alveolar crest lengths, arch circumference, and bilateral posterior volumetric measures exhibited an increase. After NAM, the anterior arch width was comparable between the treatment and control groups, whereas the posterior arch width and anterior vertical deviations were greater in the treatment group than in the control group. The maxillary arch depths, alveolar crest lengths, and maxillary volumes were smaller in the NAM group than in the control group. Conclusions: During NAM in infants with UCLP, the cleft width and anteroposterior and transverse alveolar dimensions exhibited a decrease while the vertical dimensions were maintained. Compared with infants without clefts, those with UCLP treated by NAM exhibited sagittal and vertical alveolar growth deficiencies and tissue insufficiency.

  • Patients with unilateral cleft lip and palate (UCLP) usually present unilateral cross bite due to collapse of the maxillary minor segment. Unequal expansion of the palate is needed to resolve this problem in UCLP patient. Unilateral segmental palatal distraction (USPD) after Le Fort I osteotomy and the oblique placed orthodontic expansion screw (Hyrax) can be used to correct the unilateral cross bite. 1his case report describes the effects of USPD of the collapsed maxillary minor segment on patient with unilateral cleft lip and palate.

  • Objective: In this study, we aimed to examine the relationship between chin deviation and the positional and morphological features of the mandible and to determine the factors that contributed to chin deviation in individuals with a unilateral cleft lip and palate (UCLP). Methods: Cone-beam computed tomography (CBCT) images of 28 adults with UCLP were analyzed in this study. Segmented three-dimensional temporomandibular fossa and mandible images were reconstructed, and angular, linear, and volumetric parameters were measured. Results: For all 28 individuals, the chin was found to deviate to the cleft side by 1.59 mm. Moreover, among these 28 individuals, only 7 showed distinct (more than 4 mm) chin deviation, which was toward the cleft side. Compared to the non-cleft side, the mandibular body length, frontal ramal inclination, and vertical position of the condyle were lower and inclination of the temporomandibular fossa was steeper on the cleft side. Furthermore, the differences in inclination of the temporomandibular fossa, mandibular body length, ramus length, and condylar volume ratio (non-deviated/deviated) were positively correlated with chin deviation. Conclusions: UCLP individuals show mild chin deviation to the cleft side. Statistical differences were noted in the parameters that represented positional and morphological asymmetries of the mandible and temporomandibular fossa; however, these differences were too small to indicate clinical significance.
