Frailty는 노인에서 장애와 사망의 주된 원인이 되는데 근육 감소증, 근력 약화, 에너지/화동력/보행속도의 감소, 염증성 싸이토카인의 증가를 특징으로 한다. 비타민 D의 결핍 또는 저항증은 근육기능과 단백질 합성에 대한 효과, 염증성 싸이토카인의 표현 조절, 혈관계에 대한 영향, 중추신경계에 대한 영향을 통해 Fraity syndrome에 대한 원인인자가 될 수 있다. 따라서 만약 비타민 D 결핍이 이 증후군의 중요한 요인이라면 비타민 D 투여는 안전하고도 비용-효과적인 Frailty syndrome에 대한 예방 및 치료 방법이 될 수 있는 것이다.

This study aims to plan connecting living facilities considering on the Barrier Free Walking of the disabled and the elderly in the residential area. We had found several physical problems on the pedestrian's way that becomes the major factor of disturbing the barrier free movement for using living facilities in the local area by investigations and enquetes. We had suggested the arrangement method for these physical problems on the pedestrian's way and building the ideal area for living facilities by the disposition stages with the result of investigations and enquetes. After these process, we had planned connecting living facilities considering on the Barrier Free Walking of the disabled and the elderly in the residential area.

This paper advances the software, hardware and mechanical design that the visually impaired can recognize the position and distance of the obstacle while walking. The first software implementation is proposed a method to implement the algorithm graph for the ratio of the distance measuring ultrasonic sensors for voltage. And it was extracted by the precise distance measuring parameter values from simulation to measure the precise distance. Second hardware implementation was designed to be able to detect obstacles in a relatively simple sensor-based walking aid for the visually impaired. In addition, using the switching regulator IC of high performance it was designed to be used to boost the Li-ion battery 3.7V to 5V. The third mechanism was developed by analyzing the sensor angle and the cane angle.

In this study, crutch and crutch gait for the handicapped in the lower extremity were discussed, and the study was conducted as a part of long-term research that suggests a practical solution for a crutch design. Three axillary crutches were evaluated in the study by a set of design guidelines for crutches delivered from the advanced research. In this comparative study with axillary crutch design variations, 31 healthy subjects were participated and three crutches were evaluated by ten guidelines. The result showed that Mobilegs-ultra and In-motion Pro were significantly greater than KM Crutch. However, no statistically significant difference was found between Mobilegs-ultra and In-motion Pro. While analyzing with guidelines, Mobilegs-ultra and In-motion Pro were significantly greater than KM Crutch for 6-guideline, but no significant difference was found among three crutches for the guidelines related with Lightweight and Economical feasibility and marketability. The result of the study is expected to be used for a solid foundation to evaluate for the reasonableness of the guidelines with comprehensive analysis for crutch gait evaluation in the further study.

The purpose of this study is to assess the ability of balance control in virtual moving surround stimulation using head mount display (HMD) device and force platform in patients with brain injury. Fifteen patients with stroke (mean age 54.47 yrs) and fifteen healthy normal persons participated. COP parameters were obtained total path distance, frequency of anterior-posterior and medial-lateral component by FFT analysis, weight-spectrum analysis in the two different conditions; (1) during comfortable standing with opened or closed eyes, (2) during virtual moving surround stimulation delivered using HMD with four different moving pattern. Moving patterns consisted of close-far, superior-inferior lilting (pitch) , right-left tilting (roll) and horizontal rotation (yaw) movement. In all parameters, the test-retest reliability was high. Also, the construct validity of virtual moving surround stimulation was excellent (p＜0.05). A posturographic balance assessment system equiped with virtual moving surround stimulation using HMD is considered clinically useful in evaluation of balance control in patients with brain injury.

The purpose of this study was investigate the effect of rehabilitation exercise using a home video game(PS2, Sony) on gait ability in the chronic stroke patients. The subjects of this study were 32 patients who underwent stroke for more than 6 months and were assigned to a game-based exercise group (n=16) or a control group (n=16). The Game-based exercise group executed a rehabilitation exercise three times a week during 6 weeks, at the rehabilitation unit. The exercise was performed by PS2 for one hour. Control group maintained their usual life without application of exercise. Outcome measures included gait ability. After the completion of the game-based exercise, 10m walking velocity was improved significantly (p<0.05). Six minute walking distance was increased significantly (p<0.05). These results showed that the rehabilitation exercise using a home video game is effective in the improvement of gait ability in chronic stroke patients. This study suggest that interesting, motivating game-based rehabilitation exercise and effective in recovery of function exercise for chronic stroke patients should be necessary to develop and apply.

The purpose of this study is to investigate the actual conditions of the mobility convenience facilities for pedestrians and their perception of the facilities, and thereby provide fundamental material necessary to establish a strategy of improving mobility convenience facilities. This study tried to analyze the characteristics of the mobility convenience facilities for pedestrians. Based on previous studies and "Report of Mobility Facilities of the Mobility Handicapped", this study first chose the evaluation items related to mobility convenience facilities, and then conducted a questionnaire survey and Importance-Performance Analysis (IPA). According to the study results, first, the item that needs intensive improvement was sidewalks, and the detailed indicators for sidewalks were walking safety, convenient facilities for the disabled, and pavement in order. Secondly, the items that need to be maintained were bus and crossroad. Thirdly, the low-ranking items were under-passageway and pedestrian overpass. And lastly, the items that need to be controlled were facilities for passenger terminals and bus terminals. Based on the comprehensive IPA result, this researcher judged the actual use conditions of the mobility convenience facilities in Buyeo-gun, Chungcheongnamdo. Therefore, it was found that it would be urgent to improve the direct walking environment on sidewalks. In this aspect, for future policy decision and facility maintenance, it is desirable to put the item in priority in terms of investment and come up with an improvement strategy.

Urban Designers and Planners are interested in creating barrier-free (BF) environments as the demand for social equity increases. BF design consists of design strategies for modifying buildings or facilities to be used by the physically disadvantaged or disabled. To construct buildings or facilities to be "Barrier-free", design standards specifically modified for the physically disadvantaged or disabled should be applied. The purpose of this study is to analyze the BF design standard used in the national laws and provide suggestions for their future improvements. In the study national laws in four countries were reviewed and important BF standards to be used in the laws were identified using a frequency analysis. The results of the frequency analysis were applied to the BF assessment criteria for sidewalk design. Then a field assessment for two sidewalks located in Seoul metropolitan region was conducted using the refined BF criteria. The findings from the field assessments indicated that current regulations were not appropriately designed to provide sufficient convenience for the disabled. It is needed to enhance the BF standards in the domestic regulations to offer sufficient mobility to the physically disadvantaged or disabled.
