The author studied and analyzed statistically 112 adults female ranging in age from 18 to 20 years with normal occlusion, 56 adults female ranging in age from 18 to 24 years with deep overbite and 53 adults female ranging in age from 18 to 28 years with open bite by vertical cephalometric analysis. The results were as follows; 1. In comparing normal occlusion with deep overbite and open bite, skeletal linear measurements were more significant than dentoalveolar linear measurements. SN-MP angle, SN-OP angle, PP-OP angle and Xi angle (ANS-Xi-Pog) were significant in anglular measurements. 2. Upper posterior facial height (SE-PNS), upper anterior alveolar height, lower posterior alveolar height, lower posterior alveolar height/lower anterior alveolar height and SN-PP angle were non significant between deep overbite and open bite. 3 The most significant items between deep overbite and open bite were lower anterior facial height (ANS-ME) and SN-MP angle. 4. Correlation coefficients of angular measurements were higher in deep overbite, while that of linear measurement total anterior facial height (N-ME) was higher in open bite. 5. In the multiple regression equation, significant variables were total anterior facial height (N-ME), lower anterior alveolar height, upper anterior alveolar height, upper posterior alveolar height, Xi angle (ANS-Xi-Pog) and ramus height (AR-Go) in deep overbite, and total anterior facial height (N-Me), lower anterior alveolar height, ramus height (AR-Go), lower posterior alveolar height, PP-MP angle and upper posterior facial height (SE-PNS) in open bite.

The treatment of TMJ ankylosis poses a significant challenge because of technical difficulties and high incidence of recurrence. TMJ ankylosis has been treated by excision and total joint reconstruction with alloplastic, allogeneic, autogenous materials as interpositional materials. The temporalis myofascial flap had been considered to be a successful interpositional material, due to its anatomical, topographical, and functional properties. This study evaluated the efficacy of the temporalis myofascial flap for nine TMJs (five patients) through the preauricular approach and coronoidectomy. Radiographic and physiologic long term result was investigated in this study. The result reveals that the temporalis myofascial flap is a good autogenous tissue satisfying the criteria of an ideal interpositional material, which offers a material that fulfills the physiological function of the disc. In spite of favorable functional outcome, mild postoperative openbite tendency remains another challenge.

The importance of web accessibility becomes important due to a legal obligation to comply with web accessibility. However, there are few educational programs developed on web accessibility for vocational high schools in Korea. In this study, to explore the future possibilities of web accessibility curriculum the survey with information teachers of 97 vocational high schools was conducted along with review of the curriculums of the domestic and foreign web accessibility educational programs. The survey results indicate that (1) the information teachers have only basic conceptual understandings on web accessibility and (2) they have little intention on teaching web accessibility at their vocational high schools due to current educational conditions and the lack of web accessibility knowledge. The results of this study could be employed as references for the web and web accessibility educational courses at the vocational high schools.

Purpose: This study evaluated the postoperative stability of counter clockwise rotation of the mandibular plane in anterior openbite patients, who have had one jaw surgery performed. Methods: This study includes patients with skeletal class III malocclusion accompanied by anterior openbite among the patients who have had BSSRO performed, resulting in counter clockwise rotation of the mandibule. We excluded the patients with genioplasty and segmental surgery, and included 23 patients who underwent BSSRO. Results: We found no statistical significance between the amount of counter clockwise rotation in the mandible in the Pearson correlation test. Also, there was no significant difference between Group 1 (< $3^{\circ}$) and Group 2 (> $3^{\circ}$). Conclusion: This study evaluated the amount of horizontal relapse, and the degree of relapse. Stable results were obtained. Although there was no statistical significance between the degree of openbite and the amount of horizontal relapse, the group with a greater amount of openbite had a greater amount of relapse.

The purpose of this study was to evaluate the change of before and after treatment of anterior openbite malocclusions treated by Multiloop Edgewise Archwire technique. The openbite sample consisted of 4 male and 12 female adults, treated with nonextraction or third molar extraction. The normal sample consisted of 58 subjects, which have pleasing facial profile and normal occlusion and no experience of orthodontic or prosthodontic treatment. The 58 subjects of normal sample were subdivided by cephalemetric vertical relationship of face. The 40 subjects, cephalometric vertical relationship of face was in normal range, classified as Normal Sample group 1. The 18 subjects, increased cephalometric vertical relationship of face, classified as Normal Sample group 2. The computerized cephalometric analysis was accomplished with 50 reference points for 22 skeletal measurements, 46 dentoalveolar measurements, 8 soft tissue measurements. Statistical analysis of the data was carried out with paired t-test, Student's t-test, and DUNCAN test using SAS(PC version), The results were as follows : 1. There were no statistically significant differences in skeletal measurement between before and after treatment. The major changes were in dentoalveolar region. 2. After treatment, the long axis of maxillary and mandibular posterior teeth were distally tipped-back, and uprighted to bisected occlusal plane. The interincisal angle was increased. 3. There were no statistically significant increase in the upper posterior dental height and statistically significant decrease in the lower posterior dental height. The upper anterior dental height was increased, but there was no statistically significant increase in the absolute upper anterior dental hight. The lower anterior dental height was increased. 4. After treatment, the maxillary occlusal plane to palatal plane angle and the mandibular occlusal plane to mandibular plane angle were statistically significant increased. Then, there were no statistically significant difference between after treatment group and normal sample group 2. 5. After treatment, the percentage of upper lip length to upper anterior dental height was decreased. Then, There were no statistically significant difference between after treatment group and normal sample group 2.

The author compared patients showing two extremes of incisor vertical relationship to find out differences in craniofacial morphology which might influence face height and incisor overbite. The subjects consisted of 53 open-bite cases and the same number of deep-bite cases. The results were as follows: 1. On the average, the lower face height was significantly greater in open-bite cases than in deep-bite cases. 2. In open-bite cases, gonin-menton length was significantly greater than in deep-bite cases. In deep-bite cases, anterior cranial base length and posterior cranial base length were significantly greater in open-bite cases. 3. The jaw angle was significantly greater in open-bite cases. 4. The gonion-menton-nasion angle was significantly greater in deep-bite cases. 5. From geometric standpoint, the increase of jaw and joint angle would increase lower face height, but these two showed negative correlation. 6. The sizes of the jaw and joint angle might be factors of open-bite or deep-bite, but these were not the only variables that determined lower face height. 7. In open-bite cases, there was a closer correlationship between lower face height and the other linear measurments than in deep-bite cases. In deep-bite cases, there was a closer correlationship between lower face height and the other angular measurements than in open-bite cases. 8. Considering both linear and angular measurements of facial polygon, all contributed significantly to the lower face height. The nonsignificant variables were jaw and joint angle in open-bite cases, and anterior cranial base length, jaw angle, and joint angle in deep-bite cases.

Cerebral palsy is an umbrella term encompassing a group of non-progressive non-contagious motor conditions that cause physical disability in human development. Motor disorder of cerebral palsy is often accompanied by disturbances of sensation, perception, cognition, communication, behavior and seizure disorder. Disharmony of motor function leads to frequent falling down. Moreover patients have high prevalence of class II malocclusion. Compared to normal patients, the patients with cerebral palsy tends to have high prevalence of recurrent trauma and bruxism which make restoration of the anterior tooth more difficult. This case report is consisted of three cases of cerebral palsy patients who have challenging problems with restoration of anterior teeth.

This study was conducted to identify the factors affecting nursing students' adjustment to college life. 364 students from six different nursing colleges were recruited into the study. The data were collected using questionnaires about bullying, peer support, ego-resilience and adjustment to college life and were analyzed using IBM SPSS 19.0 program. Data were collected from March 3rd, 2014 to December 12th, 2015. The results indicated that bullying(r=-.24, p<.001) had a significant negative association with nursing college adaptation. And adjustment to college life was positively correlated with peer support(r=.38, p<.001) and ego-resilience(r=.69, p<.001). The significant predictors of adjustment to college life were ego-resilience (F=334.33, p<.001), peer support(F=60.86, p<.001) and bullying(F=22.03, p<.001), explaining 47% of the variance. Based on the study results, we suggest that it is necessary to develop and apply the educational strategy to improve the peer support and ego-resilience for the adjustment to college life.
