In 2026, in ten years from now, Korea is expected to enter into a super aged society. By facing this social phenomenon, analyzing the elderlies and preparing measures are needed among society. In the transportation field, the traffic accidents which are related to the elderly pedestrians have drastically increased so that R&D projects and policy supplementations are introduced. However very few base studies on which focused on the behavior, capability, impact factors analysis of for elderly pedestrians are conducted. To determine the walking capability, this study divided the walking capability into 3 three categories - general, health and exercise. It carries out the comprehensive survey targeting 52 elderlies with the average age of 72.6 years and this survey is made up of total 12 factors in the 3 three categories. This survey also is conducted with various measuring devices and methods such as interview, National Fitness Award, SPBB, Cybex and the like for. From the 12 detailed factors, the general factors such as age, physical shape and so forth have little impact on the walking speed. However the factors that have the greatest impact on the walking speed are extensor muscle on lower limbs in the health factors and balance, coordination, and SPPB in the exercise factors. With these results, this study develops the independent walking model which can measure the walking capability of the elderly people. The developed model is expected to be utilized as the base study for elderly's walking patterns in the transportation field by examining the walking capability of the older people.

We developed a human-sized BWR(biped walking robot) named KUBIR1 driven by a new actuator based on the ball screw which has high strength and high gear ratio. KUBIR1 was developed to walk autonomously such that it is actuated by small torque motors and is boarded with DC battery and controllers. To utilize the information on the human walking motion and to analyze the walking mode of robot, a motion capture system was developed. The system is composed of the mechanical and electronic devices to obtain the joint angle data. By using the obtained data, a 3-D graphic interface was developed based on the OpenGL tool. Through the graphic interface, the control input of KUBIR1 is performed.

In Korea, which is entering a super-aged society, the number of elderly patients who have difficulty walking independently is expected to increase rapidly, and it is necessary to develop wheelchair products with various functions to improve the quality of life of people with walking disabilities. Recently, wheelchair power assist devices that provide propulsion power by being attached to a manual wheelchair has been developed and is entering the domestic and global markets. In this study, we compared and analyzed the process of obtaining medical device certification for wheelchair power assist devices in Korea, the United States, and Europe. In Korea, a Class 2 medical device certification process was developed in 2021, and in the US FDA, it corresponds to Class 2 like the existing electric wheelchair and must pass the 510k certification process. In the case of Europe, it is uniquely regulated as Class I, and the CE mark can be attached through a relatively easy self-declaration of conformity. The Korean medical device industry, which is struggling with MDR certification, a new European medical device regulation, should pay attention to the relatively easy entry into the global market for wheelchair power assist products.

Healing Yoga is old women know the change of stress and physical ability. The purpose of the study, to live a healthy life articles. Research for A living in the city. And B goes to the welfare center. The elderly women over the age of 65 and have no problem with physical activity in daily life. 8 experimental group control group 8 to 12-week healing yoga. Body composition and physical ability in the experimental group had changed. The change of stress levels, there was no statistical change in the sub factors. The average value by deep social role in the exam group many growth and self-reliance. Depressed, sleep disorders, general health and vitality in the control group showed a reduction greater than the factors.

This study is to look into the effectiveness of fall-preventive occupational therapy of elderly by clarifying the influence of occupational therapy applied to female elderly in the community upon balance ability. A 6-week occupational therapy program including both training and exercise for prevention of fall down was applied by dividing into 13 persons of experimental group and 13 persons of control group for female elderly aged more than 65 years who were capable of independence gait and have not taken any drug to adversely affect balance. For balance ability assessment, the Berg balance scale and the Tetrax fall index were used. The Berg balance scale in experimental group was shown to be 48.38 to 50.69 through the 6-week program, indicating changes in significance level(p=.017). The Tetrax fall index in experimental group was shown to be 46.77 to 35.54 through the 6-week program(p=.000). Changes in significance level were not found for both the Berg balance scale and the Tetrax fall index in control group. As seen from the results of this study, it is found that 6-week application of the fall-preventive occupational therapy program including fall prevention training and exercise was effective for promotion of elderly's balance ability, and further studies just on the effect of fall prevention training are required to be made.

Objective : The aim of this study is to prove the effects of mental practice in balance ability of elderly population, and to investigate the possibility of application as an effective intervention method for fall prevention. Methods : This study provided mental practice to 3 subjects over 65 years old who have experienced fall, but do not have cognitive dysfunctions and independent in gait without any use of assistive devices from July to October, 2013. Within the individual case study, 4 sessions of initial baseline process (A), 5 sessions of mental practice (B), 4 sessions of re-initial baseline process (A') were proceeded using ABA design. Independent variable used mental practice for enhancing balance ability and fall efficacy in elderly population, and dependent variable were Berg Balance Scale (BBS) to find out the change in overall balance ability, Fall Efficacy Scale (FES) to see the change in fall efficacy, One-Leg Standing test(OLS), and Timed Up and Go Test (TUG) to determine the changes in both static and dynamic balance. Analysis of the results were provided via mean value and graph. Results : After the application of mental practice method, all of the subjects have shown increase in fall efficacy baseline values, and in addition, overall balance ability and both static and dynamic balances either increased or maintained. Conclusion : This study demonstrated that mental practice has positive effects on fall efficacy improvement and maintenance in elderly, thereby suggesting mental practice for fall prevention in elderly populations.

Purpose: The purpose of this study is to propose a direction planning integrated waterfront cultural city in terms of urban economic revitalization through regeneration of former industrial harborfront and the creation of cultural living spaces based on regional history in order to pursue urban activities. Method: Analyzing planning waterfront and historical cultural space based on MM21's development policy and strategy under the growth process and development of Yokohama. Results: MM21 is the core public project out of the six major projects promoted by Yokohama, which is on the brink of satellite cities for the expansion of Tokyo with a goal of qualitative transformation of former harbor. It is planned to be developed as a creative cultural waterfront city for an integrated urban development. Conclusion: Planning waterfront cultural city, which takes advantage of the former harbor city derived through MM21 analysis, provides the cityscape towards the sea and the port via the viewing point and opens the waterfront open to the port and the sea Space and Esplanade landscape development, preservation of historic buildings and cultural assets, recycling as cultural art space, waterfront space planning that cooperates with public culture art and pedestrian network.
