PURPOSE: The purpose of the present study was to examine the effect of gluteal taping on posture and balance during standing in children with hemiplegic cerebral palsy (CP). METHODS: The subjects of this study were 13 children (six females, seven males; mean aged 8.5) with hemiplegic CP who were gross motor function classification system (GMFCS) level I. The change of posture and balance during standing before and after gluteal taping were measured using inclinometer, gross motor function measure, and functional reaching test. The collected data were analyzed using the paired t-test. RESULTS: The results of this study were as follows : 1) There were statistically significant decrease in the ant. tilt angle of pelvis after gluteal taping in children with hemiplegic CP (p<.05). 2) There were statistically significant increase in functional reaching test after gluteal taping (p<.05). 3) There was no statistically significant difference in gross motor function measure, but significant increase in one leg standing was observed (p<.05). CONCLUSION: As the above results, we suggest that gluteal taping could be effective on improving body alignment and dynamic balance ability during standing in children with hemiplegic CP. Further studies will be required for the short and long term effects of gluteal taping on improving postural symmetry and balance.

The dynamic responses of human standing postural control were investigated when subjects were exposed to long-term horizontal vibration. It was hypothesized that the motion of standing posture complexity mainly occurs in the mid-sagittal plane. The motor-driven support platform was designed as a source of vibration. The AC Servo-controlled motors produced anterior/posterior (AP) motion. The platform acceleration and the trunk angular velocity were used as the input and the output of the system, respectively. A method was proposed to identify the complexity of the standing posture dynamics. That is, during AP platform motion, the subject's knee, hip and neck were tightly constrained by fixing assembly, so the lower extremity, trunk and head of the subject's body were individually immovable. Through this method, it was assumed that the ankle joint rotation mainly contributed to maintaining their body balance. Four subjects took part in this study. During the experiment, the random vibration was generated at a magnitude of $0.44m/s^2$, and the duration of each trial was 40 seconds. Measured data were estimated by the coherence function and the frequency response function for analyzing the dynamic behavior of standing control over a frequency range from 0.2 to 3 Hz. Significant coherence values were found above 0.5 Hz. The estimation of frequency response function revealed the dominant resonance frequencies between 0.60 Hz and 0.68 Hz. On the basis of our results illustrated here, the linear model of standing postural control was further concluded.

Purpose: This study was examined to improve the standing posture of a scoliosis client using the ICF Tool. Methods: For examination, the study subject was a 16-year-old female student diagnosed with 3curve-pelvic (3CP) type scoliosis. Information about her were collected through a client interview and based on international Classification of Functioning, Disability and Health (ICF). The ICF core set was for post-acute musculoskeletal conditions, and the ICF level 2 items suggested by National Rehabilitation Information Center (NARIC) were added to the recommendations for scoliosis. For evaluation, the ICF assessment sheet was used to identify the interaction among the problems. For the diagnosis, the client's functional problems were described in ICF terms. For the prognosis, the global goals for reaching the client's functional activity and participation level were presented as the long-and short-term goals. For the intervention, a coordinative locomotor training program composed of warm-up, main exercise, and cool-down was applied 3 times a week, 50 minutes a day, for 5 weeks. For the outcome, the differences between before and after the intervention were compared with the ICF qualifier and are shown with the ICF evaluation display. Results: Clinical advantages were observed in body function and structure (7° decrease of thoracic angle, 7 score increase of trunk muscle power, 6.47s improve of one leg standing, 4 score decrease of neck pain). The activity for maintaining the standing posture, in which the client had a primary limitation, was improved. Conclusion: Applying the coordinative locomotor training program is expected to improve scoliosis client's standing posture.

The purpose of this paper is on identifying spatial structure of Palwang and Taechon village and dealing with restoration direction of village spatial structure and village groves. The results are as follows. It was identified that the standing stone for penis form is not standing stone for praying son but complementing that for enforcing enclosed function of enclosing village groves. It was considered that village entrance and entrance road, village grove of Taechon village must be restored for being identified as standing stone of penis form of spatial structure of village. It was considered that the above is essential to connect with ecotourism of Sunchang-gun region. It was identified that Palwang village grove is very good in conservation state, but Taechon village grove has been destructed mostly by various development. It was identified that Palwang village grove is high in species diversity and in scare value as mixed forest, landscape value. The dominent tree of Palwang village was Pinus densiflora and that of Taechon was Salix glandulosa. Salix glandulosa was used pavilion tree, main tree in both village. It was identified that Carpinus tschonoskii is showing the most rapid growth in tree height and Salix glandulosa is showing the most rapid growth in tree breadth diameter of all kind of tree. It was considered that Pinus densiflora was planted first of all and deciduous trees were complemented later. It was considered that simple forest of Pinus densiflora has been changed into mixed forest by artificial affect in the long term. It was considered that Salix glandulosa in Palwang village grove must be indicated as legal protection tree according to present criteria of protection tree selection in Korea. And it is considered desirable that standing stone of penis form and village grove in Palwang village must be indicated unitedly as cultural conservation element.

The increasing number of crimes in rapidly changing modern society is enhancing people's desire for safety. As of 2008, 2,900 private security businesses with 133,000 employees operated in the private security industry which emerged in response to growing demands from society and people. Of the employees, bodyguards (hereinafter referred to as "private security guard") accounted for about 10% or 13,000. Most private security guards were suffering from various occupational diseases. Especially as they needed to guard their clients many hours a day and worked in a standing position for a long time, private security guards often complained of low back pain. Under the pain, they were hardly expected to perform their tasks efficiently. There are several causes of low back pain. The most prevalent cause is muscle weakness and imbalance around low back. Especially because private security work often requires security guards to maintain a standing position for a long time, many of them are suffering from low back pain. This study pursued the following purposes. First, it tried to identify the pathogenesis of low back pain caused by muscle weakness and imbalance around low back. Second, it tried to provide private security guards, who can hardly have personal time at work, with an easy method to prevent and manage low back pain any time by researching an effective therapy for low back pain caused by muscle weakness and imbalance around low back.

To our knowledge, the imaging features of costochondral grafts (CCGs) on cone-beam computed tomography (CBCT) have not been documented in the literature. We present the case of a CCG in the facial soft tissue to the anterior mandible, with changes mimicking a cartilaginous neoplasm. This is the first report to describe the CBCT imaging features of a long-standing graft in the anterior mandible. Implants or grafts may be incidental findings on radiographic images made for unrelated purposes. Although most are well-defined and radiographically homogeneous, being of relatively inert non-biological material, immune reactions to some grafts may stimulate alterations in the appearance of surrounding tissues. Biological implants may undergo growth and differentiation, causing their appearance to mimic neoplastic lesions. We present the case of a cosmetic autogenous CCG that posed a diagnostic challenge both radiographically and histopathologically.

Mandibular condylar hyperplasia is an uncommon condition of excessive unilateral growth of the condyle causing facial asymmetry and occlusal alterations. The etiology of condylar hyperplasia is unclear, but several factors are suspected, including previous trauma, hormonal disturbances, and abnormal functional loadings. Acute or chronic recurrent dislocation of temporomandibular joint (TMJ) is common, but long-standing dislocation is rare. We present two cases of the exophytic condylar hyperplasia that lasted for over 20 years with TMJ dislocation. In both cases, we performed a condyloplasty to restore normal occlusion and facial symmetry, with satisfactory results.
