[Objective]To evaluate the joint spaces and condylar morphology among different vertical skeletal patterns to compare condylar position and morphology.[Materials and Methods]Diagnostic cone-beam computed tomography images of 80 adult patients (160 temporomandibular joints) who visited the Department of Orthodontics, Affiliated Stomatology Hospital of Medical School, Nanjing University were evaluated using Mimics 16.0 software. The subjects were divided into four equal groups based on angles classification and Frankfurt Horizontal plane-Mandibular plane Angle. Group Ⅰ included skeletal Class Ⅰ normodivergent patients whereas Group Ⅱ, Ⅲ, and Ⅳ were skeletal Class Ⅰ, Ⅱ and Ⅲ hyperdivergent patients respectively. Temporomandibular joint spaces, depth of mandibular fossa and condylar morphology and asymmetry were compared among the groups.[Results]*** difference values were seen in the anteroposterior diameter of condylar process on right (p=0.005) and left (p=0.011) side, mesiolateral diameter of condylar process on left (p=0.008) side, lateromedial plane angle of condylar process right (p=0.004) and left (p=0.00) side, axial condylar angle right (p=0.011) and left (p=0.001) side and the anteroposterior difference of the condylar processes (p=0.002) among all the four groups i.e. class Ⅰ normodivergent group and class Ⅰ, Ⅱ and Ⅲ hyperdivergent groups.2. Anterior joint space on both right (p=0.037) and left (p=0.04) side, superior joint space on left (p=0.30) and posterior joint space on both the right (p=0.013) and left (p=0.01) sides were found to be significantly different. This data suggest that the condyles in class Ⅱ hyperdivergent patients are nonconcentric than the class Ⅰ hyperdivergent patients.3. The mean anteroposterior diameter of the class Ⅱ hyperdivergent patients was R=4.33±1.56, L=4.24±1.64 and class Ⅰ hyperdivergent was R=5.37±0.84, L=5.25±1.24. The mean mesiolateral diameter of the class Ⅱ hyperdivergent group was R=10.90±3.23, L=10.00±2.84 a

Space‑Time Clustering with the Space‑Time Permutation Model in SaTScan™ Applied to Building Permit Data Following the 2011 Joplin, Missouri Tornado

Community recovery from a major natural hazard-related disaster can be a long process, and rebuilding likely does not occur uniformly across space and time. Spatial and temporal clustering may be evident in certain data types that can be used to frame the progress of recovery following a disaster. Publically available building permit data from the city of Joplin, Missouri, were gathered for four permit types, including residential, commercial, roof repair, and demolition. The data were used to(1) compare the observed versus expected frequency(chi-square) of permit issuance before and after the EF5 2011 tornado;(2), determine if significant space-time clusters of permits existed using the SaTScan^(TM) cluster analysis program(version 9.7);and(3) fit any emergent cluster data to the widely-cited Kates 10-year recovery model. All permit types showed significant increases in issuance for at least 5 years following the event,and one(residential) showed significance for nine of the 10years. The cluster analysis revealed a total of 16 significant clusters across the 2011 damage area. The results of fitting the significant cluster data to the Kates model revealed that those data closely followed the model, with some variation in the residential permit data path.
