Objective: The aim of this study was assessment of the relationship between airway space and facial morphology in Class III children with nasal obstruction. Methods: For this study, 100 Class III children (50 boys and 50 girls) were chosen. All subjects were refered to ENT, due to nasal obstruction. Airway space measurements and facial morphology measurements were measured on lateral cephalometric radiograph. Pearson correlation analysis was used to assess the relationship between airway space and facial morphology Results: Ramal height, SNA, SNB, PFH, FHR and facial plane angle were positively related to upper PAS, and sum of saddle angle, articular angle, and genial angle, SN-GoGn, Y-axis to SN and FMA negatively related to upper PAS. Genial angle, FMA were positively related to lower PAS, and articular angle, facial depth, PFH and FHR negatively related to lower PAS. PCBL, ramal height, Mn. body length, Mn. body length to ACBL, facial depth, facial length, PFH and AFH were positively related to tonsil size. Sum of saddle angle, articular angle, genial angle, facial length, AFH, FMA and LFH were positively related to tongue gap, and IMPA and overbite was negatively related to tongue gap. Upper PAS, related to size of adenoid tissue, was mainly related to posterior facial dimension following a vertical growth pattern of face and mandibular rotation. Lower PAS and tonsil size, related to anterior-posterior tongue base position, were significantly related to each other. Lower PAS was related to growth pattern of mandible, and tonsil size was related to size of mandible and horizontal growth pattern of face. Tongue gap was related to anterior facial dimension following a vertical growth pattern of face. Conclusion: Significant relationship exists between airway space and facial morphology.

The purpose of this study was to provide useful data for clinical occupational therapy by examining the correlation between the use of affected and unaffected sides measured using an accelerometer and upper limb function in chronic stroke patients. In this study, accelerometer, Fugle-Meyer Assessment(FMA), Motor Activity Log(MAL), and Yonsei-Bilateral Activity Test(Y-BAT) was measured on 40 stroke patients who were hospitalized in Won-ju city Y hospital between May 2, 2019 and July 18, 2020. As a result of the study, there was a significant negative correlation between amount of use on the unaffected side and FMA and MAL's Amount of Use(AOU), Quality of Movement(QOM), the quality and satisfaction of performing both hands through Y-BAT. The amount of use on the affected side showed a significant positive correlation with FMA and MAL's AOU, QOM, satisfaction of performing both hands. This study is meaningful in that it suggested the possibility that the actual amount of use on the affected and unaffected side measured using an accelerometer could be used as an evaluation item for upper limb function in stroke patients.

1. 서론 : 최근 낮은 에너지 소비, 적은 투자설비비로 인하여 분리기술 분야에 분리막을 적용시키는 연구가 활발히 진행되고 있으며 상업화 추진도 진행중에 있다. 특히 기체 분리 시장에서 분리막의 이용이 연구되고 있으나, 일반적인 분리막들이 가지고 있는 공통적인 특징인 투과도가 높아지면 선택도가 낮아지고, 반대로 선택도가 높아지면 투과도가 낮아지는, trade-off현상으로 인하여 분리막의 사용에는 많은 제약이 따르게 되었다. 따라서 이를 방지하기 위한 연구가 진행중이며 그로부터 얻은 결과중 하나가 6FDA를 이용한 polyimide 분리막의 적용이다.(생략)

The concept of denture frame, both the vertical and horizontal relationship of the dentitions are ultimately related to a skeletal configuration, leads to postulate that the vertical overbite will be determined by the jaw rotations and anteroposterior jaw relationship. Also, ODI is analyzed to be composed of the determinant factors of overbite such as FMA PPA and FABA. From the geometric analyses of an interrelationship between the ODT and the overbite determinants, the following formula can be induced. ODI norm=$85^{\circ} - 0.5 PMA-(1.08 - 0.01 FMA)(FABA - 81^{\circ})$. This formula indicates that the norm of ODI is not constant value but variable one according to the individual skeletal frames. Through the application of the formula to the various clinical cases, it is proved that the new concept, relativity of the ODI norm, is very diagnostically useful.

Purpose: In real life there are both straight-paths and curved-paths. To evaluate walking ability of both kinds, a figure-8 walking test (F8WT) was developed. The aim of this study was to validate the measure in hemiplegic patients with walking difficulties and to identify correlations of curved walking ability with straight walking ability, motor function, and walking performance ability. Methods: Twenty subjects participated in this study. Curved walking was measured by a F8WT. Straight walking ability was measured by a 10-meter walking test (10MWT). Dynamic balancea bility was measured by timed up and go (TUG) tests. Walking performance ability was measured using a modified motor assessment scale (MMAS). Motor function was measured by the Fugl-Meyer assessment (FMA) scale. Data were analyzed using Pearson correlation analysis. Linear regression analyses were performed to explore other functional tests in mobility ability by F8WT time, 10MWT (dependent variable). Results: There was a significant positive correlation of F8WT time with 10MWT and TUG. There was a significant negative correlation of F8WT time with MMAS and FMA-coordination. There was a significant positive correlation of 10MWT with TUG. There was a significant negative correlation of 10MWT with MMAS and FMA-coordination. The F8WT time for curved walking ability was attributed to 10MWT for straight walking ability as 94% level of contribution. Conclusion: The results suggest that the F8WT is a good instrument for measuring walking ability because there is a robust correlation of F8WT time with 10MWT, TUG, MMAS, and FMA-coordination in hemiplegic patients who, after stroke, have a mobility deficiency.

The purpose of this study was to examine the effect of the upper limb nerve mobilization (ULNM) on functional recovery of upper extremity in hemiplegic patients following stroke. Twenty patients who had functional impairment on upper extremity were participated. Subjects were randomly divided into two groups: Control group (n=10) received traditional physical therapy only for 4 weeks; Experimental group (n=10) received ULNM treatment along with traditional physical therapy for the same period. Upper extremity functions were assessed by manual muscle test (MMT), modified Ashworth scale (MAS), and Fugl-Meyer assessment (FMA) before and after the treatment. In both experimental and control group, upper extremity functions were significantly improved in MMT (p<.01) and FMA (p<.01), however only experimental group showed significant improvement in FMA after the treatment (p<.05). Moreover, experimental group showed significantly greater improvement than control group in MMT (p<.05), MAS (p<.05), and FMA (p<.05). We conclude that the upper extremity functions is a useful additional therapeutic technique for the effective treatment of upper extremity deficits in hemiplegic patients.

Purpose: The purpose of this study was to investigate the effects of a modified constraint induced movement therapy (mCIMT) using proprioceptive neuromuscular facilitation (PNF) on the upper extremity function and activities of daily living (ADLs) in patients with subacute stroke. Methods: Fourteen participants with subacute stroke were randomly assigned to a group using both mCIMT and PNF or a group using mCIMT alone. Each group underwent twenty sessions (1 h/d, 5 d/wk) for 4 weeks. Patients were assessed with the action research arm test (ARAT), the Fugl-Meyer assessment for the upper extremities (FMA-UE), the Modified Barthel Index (MBI), and motor activity logs (MALs; amount of use [AOU] and quality of movement [QOM]). Results: Both the experimental group and the control group showed significant intragroup improvement in the ARAT, FMA-UE, MBI, and MAL-AOU (p<0.05). The group using both mCIMT and PNF exhibited greater improvement in the ARAT, FMA-UE, MBI, and MAL-AOU than did the group using mCIMT alone. Statistical analyses showed significant differences in the ARAT (p=0.01), FMA-UE (p=0.01), MBI (p=0.00), and MAL-AOU (p=0.01) between the groups. Conclusion: This study applied mCIMT combined with PNF for subacute stroke patients, and the results showed significant improvements in the patients' upper extremity function and ADLs. Therefore, mCIMT using PNF may be more effective than mCIMT alone in improving upper limb function and ADLs in patients with subacute stroke.

The aim of this study was to evaluate effects of short-tenn repetitive-bilateral excercise on the activation of motor network using functional magnetic resonance imaging (fMRI). The training program was performed at 1 hr/day, 5 days/week during 6 weeks. Fugl-Meyer Assessments (FMA) were performed every two weeks during the training. We compared cerebral and cerebellar cortical activations in two different tasks before and after the training program: (1) the only unaffected hand movement (Task 1); and (2) passive movements of affected hand by the active movement of unaffected hand (Task 2). fMRI was performed at 3T with wrist flexion-extension movement at 1 Hz during the motor tasks. All patients showed significant improvements of FMA scores in their paretic limbs after training. fMRI studies in Task 1 showed that cortical activations decreased in ipsilateral sensorimotor cortex but increased in contralateral sensorimotor cortex and ipsilateral cerebellum. Task 2 showed cortical reorganizations in bilateral sensorimotor cortex, premotor area, supplemetary motor area and cerebellum. Therefore, this study demonstrated that plastic changes of motor network occurred as a neural basis of the improvement subsequent to repetitive-bilateral excercise using the symmetrical upper-limb ann motion trainer.

The aim of the present study was to examine whether mental practice (MP) in conjunction with repetitive transcranial magnetic stimulation (rTMS) can improve the upper limb function of sub-acute stroke patients. This study was conducted with 32 subjects who were diagnosed with hemiparesis by stroke. The experimental group consisted of 16 members upon each of whom was performed MP in conjunction with rTMS, whreas the control group consisted of 16 members upon each of whom was performed MP and sham rTMS. Both groups received traditional physical therapy for 30 minutes a day, 5 days a week, for 6 weeks; additionally, they received mental practice for 15 minutes a day. The experimental group was instructed to perform rTMS, and the control group was instructed to apply sham rTMS for 15 minutes. A motor cortex excitability analysis was performed by motor evoked potentials (MEPs), and upper limb function was evaluated by Fugl-Meyer Assessment (FMA) and the Box and Block test (BBT). Results showed that the amplitude, latency, FMA, and BBT of the experimental group and the latency, FMA, and BBT of the control group were significantly improved after the experiment (p<0.05). Significant differences were found between the groups in amplitude and latency after the experiment (p<0.05). The results showed that MP in conjunction with rTMS is more effective in improving upper limb function than MP alone.
