Functional requirements and design parameters were not clarified in the early design process. Design axiom shows some difficulty for larger system designs, such as the butterfly valve, which is basically carried out by an incremental and iterative process. A numerical analysis was carried out on fluid flows in a butterfly valve, by using ANSYS-FLOTRAN. Characteristics of the butterfly flows at different valve disk opening angles, with a uniform incoming velocity, were investigated. The entire analysis is decomposed to satisfy the independence axiom. This paper resolves the problems associated with the establishment of a systematic design process.

This study was conducted to examine the effects of the application of family-centered training over the 12-week period by the pediatric physiotherapist on functional balance and activities of daily living in children with cerebral palsy. Among the 26 children with cerebral palsy as the subjects were allocated to the experimental and control group. Both groups were subjected to neurodevelopmental treatment by the pediatric physiotherapist. The experimental group, participated in family-centered training program 3 times a week over a period of 12 weeks for the total of 36 sessions, functional balance and activities of daily living were verified through intergroup comparison. There was no significant difference between the outcomes prior to training and after 6 weeks of training, (p>.05) Pediatric Berg's Balance Scale(PBS) and Functional Independence Measure for children(Wee-FIM) increased significantly from those measures after 6 weeks to those after 12 weeks of training (p<.05). Therefore, these results suggest that on family-centered training on children with cerebral palsy has beneficial effects on functional movements and physical activities.

This paper addresses the methodologies for manufacturing systems design. While a number of design methods are used in product or part design, methods for manufacturing systems design are rarely known. Two approaches, simulation and axiomatic design theory, are discussed with respective case examples. The usual purpose of using simulation is to identify the bottleneck of a manufacturing system or to evaluate its performance with the aim of configuring the manufacturing system. The simulation typically proceeds in steps such as problem definition, model building, numerical experimentation, analysis and evaluation. The axiomatic design method transforms customer attributes into functional requirements and repeats mapping processes between functional domain and physical one until a satisfactory level of refinement of the functional requirements and the design parameters is reached. Possible design alternatives are evaluated by applying the independence axiom as well as the information axiom.

The Purpose of this study was to investigate correlations between the Mini-Mental State Examination (MMSE) and the Functional Independence Measure (FIM) in strokes. The data collected retrospectively from fifty-five stroke rehabilitation patients. The MMSE and FIM at the time of admission and discharge were obtained from patients' medical records. Firstly, Pearson correlation coefficients of the MMSE score at the time of admission revealed $0.286{\sim}0.747$ with FIM at the time of discharge (p<0.05). Also, the change of MMSE score significantly correlated with the change of total FIM scores in strokes (r=0.409, p<0.05). Because the MMSE scores at the time of admission and FIM at the time of discharge are correlated, the MMSE scores can be used to predict the FIM at the time of discharge and establish a rehabilitation program.

Background: The purpose of this study is to investigate changes in physical and cognitive function according to the level of independence in performing activities of daily living in stroke patients. Design: Retrospective study. Method: This study is a retrospective study analyzing medical records. This study utilized data collected from 123 stroke patients at admission in a local rehabilitation hospital between 2019 and 2022. Stroke patients were classified into 5 groups based on the scores of the Korean Modified Barthel index (K-MBI) evaluated at the time of hospitalization at a rehabilitation hospital, and investigated the change in physical (spasticity (modified Ashworth scale), muscle strength (manual muscle test), gait ability (functional ambulation category), upper extremity function (manual function test), and balance function (berg balance scale)) and cognitive function (Korean mini mental status examination) according to the level of independence in performing activities of daily living. Result:: As a results, significant differences were observed in the physical (muscle strength, gait ability, upper extremity and balance functions) and cognitive functions of stroke patients according to the level of independence in performing activities of daily living (p<0.05). However, there was no significant difference in upper and lower extremities spasticity. Conclusions: Through the results of this study, we found that the physical (muscle strength, gait ability, upper extremity and balance functions) and cognitive function were influenced by the level of independence in performing activities of daily living in stroke patients.

This study aims to compare the relationship between the Berg Balance Scale (BBS) scores, Timed Up & Go (TUG), Functional Independent Measure (FIM), and subject characteristics. All of the 18 subjects were women between the ages of 68 and 91 (mean=80.2, SD=5.43), and they all lived at the nursing home in Wonju. Balance was measured using BBS, and functional mobility was measured using TUG. FIM was used to evaluate functional independence. Data were analyzed using Spearman correlation. Statistically significant differences were noted between BBS and TUG (r=-.486, p<.05). There were no significant statistical differences between total FIM and BBS, TUG. The FIM items "locomotion" and "communication" showed significant statistical differences between BBS and TUG. The results suggest that FIM may be able to predict dangerous falls in elderly people.

A 'pusher syndrome' encompassing postural imbalance and hemi-neglect is believed to aggravate the prognosis of stroke patients. The patients with pusher syndrome show a particular posture that pushing away from the unaffected side of the body. The objective of this study was to investigate associated proprioception, associated neuro-psychological symptoms and characteristics of functional outcome with and without pusher syndrome. The subjects of this study were 58 acute stroke patients who been rehabilitated at two university hospitals in Seoul and Buchun. Data were collected using proprioception test and line bisection test. The ability of ADL was assessed by the Modified Barthel Index, transfer by the Functional Independence Measure, and balance by the Modified Motor Assessment Scale. The results were that significant difference was found in the presence of proprioception, in the incidence of hemineglect and anosognosia, and in the score of ADL, transfer and balance between patients with and without pusher syndrome. Patients without pusher syndrome gained more motor score than patients with pusher syndrome. From improvement of view, patients with pusher syndrome gained the lowest score in ability of transfer. The finding suggest that the patients with pusher syndrome is a poorer functional outcome, be related to proprioception, hemineglect and anosognosia.
