Congenital facial cleft is a rare entity and appears along by the line of different processes of the facial development. An isolated cleft of the nose has been reported not often in the literature. We treated a patient with an isolated nasal cleft associated with undefined cranial anomaly. On 3D CT scan was seen a bony cleft traversing the pyriform aperture lateral to the anterior nasal spine. The nasal septum and frontal process of the maxilla were intact. There also was found bilateral bony defects in the frontal bone and bilateral frontal boss. The nasal cleft and frontal defect and boss were corrected by two stages: anterior two-third of the cranial vault with bilateral frontal boss was remodeled at the age of two years and the nasal cleft was repaired with a local rotation flap at age 3.

Objective: To evaluate the effects of facemask therapy, which was anchored from the zygomatic buttresses of the maxilla by using two miniplates, in skeletal Class III patients with maxillary deficiency. Methods: Eighteen skeletal Class III patients (10 girls and 8 boys; mean age, $11.4{\pm}1.28$ years) with maxillary deficiency were treated using miniplate-anchored facemasks, and their outcomes were compared with those of a Class III control group (9 girls and 9 boys; mean age, $10.6{\pm}1.12$ years). Two I-shaped miniplates were placed on the right and left zygomatic buttresses of the maxilla, and a facemask was applied with a 400 g force per side. Intragroup comparisons were made using the Wilcoxon test, and intergroup comparisons were made using the Mann-Whitney U-test (p < 0.05). Results: In the treatment group, the maxilla moved 3.3 mm forward, the mandible showed posterior rotation by $1.5^{\circ}$, and the lower incisors were retroclined after treatment. These results were significantly different from those in the control group (p < 0.05). No significant anterior rotation of the palatal plane was observed after treatment. Moreover, changes in the sagittal positions of the maxillary incisors and molars were similar between the treatment and control groups. Conclusions: Skeletally anchored facemask therapy is an effective method for correcting Class III malocclusions, which also minimizes the undesired dental side effects of conventional methods in the maxilla.

Purpose : The purpose of this study was to evaluate the effect of 6 weeks of sling exercises on female patients 20 years of age with low back pain according to flexibility, balance, muscle strength and pelvic tilt. Method : The 20 female patients who complained of back pain were divided into two groups. The experimental group exercised for 40 minutes, 3 times a week for 6 weeks. The control group did not. Both groups were measure for flexibility, balance, muscular strength, and pelvic tilt angle. Result : Curvature of the experimental flexibility, stretch, balance, muscle strength of the trunk forward, backward, left rotation, right rotation for the sling exercise group had significant differences. However, pelvic tilt did not show a significant difference. Control of the stretch of the flexibility, balance, and muscle strength of the trunk posterior showed significant differences for the sling exercise group. Conclusion : Although significant differences were found in flexibility, balance, muscular strength, there was no difference in pelvic tilt. When selecting subjects, we believe patients with regular patterns of pain will be more effective for statistical analysis of the changes in pelvic tilt.

The purpose of this study was to provide fundamental information for the enhancement of performance through kinematic analysis of cornering according to the radius of curve course in short track speed skating. To perform this study, six skaters: three narrow radius players(N, body mass: $56.0{\pm}7.2$ kg, height: $163.7{\pm}5.1$ cm, age: $21.3{\pm}1.5$ yrs) and three wide radius players(W, body mass: $61.0{\pm}9.5$ kg, height: $169.0{\pm}4.4$ cm, age: $20.0{\pm}1.7$ yrs). Three-dimensional motion analysis was performed on the section from the forth block starting to show the change of radius to the sixth block using eight infrared cameras(sampling frequency of 100 Hz for N and W players). The time of push-off was greater for N than for W(p<.05) while the radius of center of mass was greater for W than for N(p<.05). The flexion and extension of knee and hip joint were greater for N than for W(p<.05). The external rotation of left knee joint was greater for N than for W(p<.05). Based on the findings, a small radius by increasing the range of the flexion and extension of knee and hip joint with greater external rotation of left knee joint would be related to more efficient run at curve. It is expected that these results will be useful in developing a training program for enhancing performance of short track speed skating athletes.

Objective: To evaluate the null hypothesis that there is no difference in a set of clinical predictors of potentially impacted canines between low-risk patients with and without displaced canines. Methods: The normal canine position group consisted of 30 patients with 60 normally erupting canines ranked in sector I (age, 9.30 ± 0.94 years). The displaced canine group comprised 30 patients with 41 potentially impacted canines ranked in sectors II to IV (age, 9.46 ± 0.78 years). Maxillary lateral incisor crown angulation, inclination, rotation, width, height, and shape, as well as palatal depth, arch length, width, and perimeter composed a set of clinical predictors, which were evaluated on digital dental casts. Statistical analyses consisted of group comparisons and variable correlations (p < 0.05). Results: There was a significant association between sex and mesially displaced canines. Unilateral canine displacement was more prevalent than bilateral displacement. The crown of the maxillary lateral incisors was significantly angulated more mesially and rotated mesiolabially in low-risk patients with displaced canines, who also had a shallower palate and shorter anterior dental arch length. Lateral incisor crown angulation and rotation, as well as palatal depth and arch length, were significantly correlated with the canine displacement severity. Conclusions: The null hypothesis was rejected. Maxillary lateral incisor angulation inconsistent with the "ugly duckling" stage as well as a shallow palate and short arch length are clinical predictors that can significantly contribute to the early screening of ectopic canines in low-risk patients.

Purpose: The present study was designed to investigate the effect of a Rollator on plantar pressure and foot balance during gait in older adults. Methods: Twenty consecutive subjects (8 men, 12 women; age: $69.9{\pm}8.9$) had the following measurements done: plantar pressure in 10 areas of the foot, foot balance including heel rotation, foot balance, forefoot balance, medial forefoot balance, and meta loading during gait with or without a Rollator. Results: Significant differences in plantar pressure were observed in the areas of toes 2-5 or etatarsal areas 1, 4, 5 during gait with and without a Rollator. There were no significant differences in other areas of the foot. Regarding foot balance during gait with or without a Rollator, there were statistically significant differences in heel rotation, forefoot balance, medial forefoot balance, and meta loading. Conclusion: For older adults, the use of a Rollator can decrease plantar pressure and increase foot balance in various foot areas.

The purpose of this study was to assess the effectiveness of taping therapy for adhesive capsulitis patients. The subjects were consisted of 40, male 18, female 22, average age was 59 years old. To find out the effectiveness of taping therapy, we sampled 20 patients treated with H/P, electrical therapy and scapular pattern & hold-relax technique of PNF(control group), and 20 patients treated same as control group with taping therapy(experimental group). The results were as follow : 1. There was a statistical significance of shoulder flexion, abduction, external rotation and VAS in both group(P<0.05). 2. There was not statistical significance of shoulder flexion and external rotation(P>0.05), but abduction had a statistical significance between taping group and non-taping group(P<0.05). 3. VAS was observed a statistical significance between 3rd and 4th post treatment(P<0.05). These results are imply that taping therapy has a effectiveness of shoulder motion and VAS for adhesive capsulitis.
