  • The purpose of this study is to review the use of a new standard impactor, the impact ball, in evaluating heavy-weight impact noises in reinforced concrete structures. A survey revealed that children running and jumping are the major heavy-weight impact sources in multi-story residential buildings. The noise from the impact ball was measured and psychoacoustically assessed. The relationship between the noise levels and the subjective responses was also investigated. Results showed that the noise from the impact ball is similar to the noise of children running and jumping. It was also found that the noise level of the impact ball is slightly higher than the noise level of a bang machine, although the impact ball has a lower impact force.

  • Floor impact noises in apartment buildings have been investigated as they are most annoying in living environment. Several experiments were undertaken to compare perceived noisiness of floor impact noises generated by bang and tapping machine along with children's jumping and running. Results show that bang noise is more annoying than tapping noise and floor impact noise generated by children is less annoying than the noise generated by machine. The floor impact noise generated by children's jumping and running corresponds well with the bang-machine noise in terms of loudness, unbiased annoyance, ${\Phi}$$\_$0/ and IACC. The noise generated by children is somewhat different from machine noise; in spatial impression the real noise is similar to tapping-machine noise but is less annoying that the machine noises.

  • Purpose : The purpose of this study was to examine the correlation between Pediatric Balance Scale(PBS) and Gross Motor Function Measurement(GMFM) with cerebral palsy(CP) children. Methods : 31 ambulatory children with CP were recruited for this study. PBS is a modified version of the Berg’s Balance Scale to access the children with motor impairments. To access the motor functions that directly influence to the functional independence of the ambulatory CP children, total scores of standing category and walking/running/jumping category of GMFM were selectively compared with PBS score by Spearman correlation coefficient analysis. Results : The results revealed high correlation between PBS and GMFM scores both in standing and walking/running/jumping categories(r=.9). Conclusions : Therefore, this study indicates that PBS can be applied not only as a tool to access balance, but also as a measurement to predict and access the level of standing and ambulatory related functions of children with CP.

  • Purpose: This study aimed to evaluate the relationships among quality of life, caregiver depression levels, and disease severity, especially motor function, in children with cerebral palsy. Methods: Data were collected through questionnaires using survey and interview from 80 caregivers of children with cerebral palsy. The caregivers' quality of life was measured using medical outcomes study 36-item short form health survey, and level of depression was scored using the beck depression inventory. In addition, children's motor function was evaluated using gross motor function measure-88 and functional independence measure scores. Results: Among 8 domains of medical outcomes study 36-item short form health survey, "physical functioning," "physical role functioning," "mental health," and "bodily pain" domains were significantly correlated to "total" percentage scores of gross motor function measure-88. In addition, "mental health" and "bodily pain" domains were correlated to each sub-dimension, including "lying and rolling," "sitting," "crawling and kneeling," "standing," and "walking, running, and jumping." Similarly, the "running" and "jumping" dimensions including motor function measures correlated with "transfer," "locomotion," and "motor subtotal" of functional independence measure scores. The beck depression inventory scores were negatively correlated to "lying and rolling," "sitting," "crawling and kneeling," and the "total" percentage scores of gross motor function measure-88. The beck depression inventory scores were negatively correlated to "sphincter control," "communication," "social cognition," "cognitive subtotal," and "total" functional independence measure scores. Conclusion: It is necessary to consider the quality of life and emotional problems of caregivers of CP children and support them both physically and psychologically with comprehensive rehabilitation.

  • Family and parents which serve as a primary group for the children's development also play important role in their cerebral palsy children's treatment. This study wants to know how the parents' participation in their children's physical therapy and satisfaction degree have an impact on their children's improvement of the motor function. For that purpose, a home made self filling survey was conducted of 156 cerebral palsy children's parents whose children were treated in 4 university general hospitals and 3 welfare centers from the 1st of April 2004 to the 31th of march 2005. The gross motor function was employed to evaluate the cerebral palsy children's motor function improvement. In this study, those questioned were divided into two groups according to the time of treatment. 'Group A' is consist of the patients whose parents attended to the treatment more than one hour at home. The patients who belonged to 'Group B' were treated less than one hour at home. The general features of the cerebral palsy children and their parents and the characteristics of their physical disability, the parents' participation and their satisfaction degree were examined by survey. Evaluating the difference between two groups' motor function according to their parents participation degree in the physical therapy leads to the following results. First, 'Group A' was better than 'Group B' in their satisfaction degree with the physical therapy and participation degree. Statistically 'Group A' was superior to 'Group B' in the requirements of the information and education for the children with cerebral palsy. Second, after two months of treatment, 'Group A' showed more statistically significant improvement than 'Group B' in every items as like lying in item 1, sitting in item2, crawling and kneeling in item 3, standing in item 4, walking,running, jumping in item 5. Third, parents' participation in physical therapy and satisfaction degree have some relevance to their children' motor function improvement. The satisfaction degree is related to motor function like crawling and kneeling in item 3, walking,running, jumping in item 5. It is showed that the parents' participation degree and information about handicapped children.

  • In order to investigate characteristics of floor impact sound generated in the apartment buildings, questionnaire survey was conducted for respondents living in apartments in 200t. Questions in the surrey were on the characteristics of real impact sounds, subjective annoyance and satisfaction on the heavy and light impact sources. From the survey results, it was found that most annoying time of a day and the space were 8 p.m. to midnight at living room. It was also revealed that the main source of the floor impact sound from the upper floor is a child's jumping and running at from six to nine. More than half of people were not satisfied on the floor impact isolation performance of their own apartments. The percentage of residents who were annoyed by the heavy-weight impact sound such as children's jumping and adult's walking was $5{\sim}10%$ lower than by light-weight impact sound.

  • The purpose of this study was to apply treadmill training through motor learning to cerebral palsy children and examine its effects on their Gross Motor Functions. The subjects of this study were 13 spastic diplegia children who had difficulty in independent gait, and GMFCS level III, IV. We performed treadmill gait training using the principle of weight bearing, based on 4times a week for 30 minutes before and after each session physical therapy we gave weight bearing treadmill training 5 to 10 minutes, during 7 weeks(April 9, 2012~May 26, 2012) fittingly for the children's gait characteristics. In order to test how the weight bearing treadmill training affects spastic diplegia children's gross motor functions, we measured body mobility with Gross Motor Function Measure (GMFM). These data were collected before and after the experiment and analyzed through comparison. Data collected from the 13 spastic diplegia children the results were as follows. For evaluating with regard to change in body mobility, significant difference was observed between before and after the experiment in measured gross motor functions, which were crawling, kneeling, standing, walking, jumping and running(p<0.05). According to the results of this study, when gait training through motor learning was applied to spastic cerebral palsy children, it made significant changes in their body mobility. Accordingly, for the effective application of gait training through motor learning to cerebral palsy children, it is considered necessary to make research from different angle on how such training affects children's mobility, activity of muscles in the lower limbs, and gait characteristics.
