This paper describes the development of a novel walking assistance robot for the elderly and infirm. In the case of simple walking assistance devices, the walking safety and effectiveness are somewhat low; hence, caregivers are frequently required. The walking assistance robot developed in this research is capable of securely and conveniently assisting a walking user by using electric motors and various devices without a caregiver. The main features include the following. First, the walking safety is improved by using a pelvis supporter, and the robot is able to follow the user effectively by means of ergonomic motion sensors and electric powered wheels. Second, it is possible to adjust the load applied to the lower body by adjusting the height of the pelvis supporter. Finally, it is possible to inform the approximate distance and direction of any obstacle around the robot using the sounds and vibrations for the blind and the hearing impaired. The performance of the developed walking assistance robot was successfully verified using a walking assistance test in a narrow-corridor environment.

Today, the public assistance program in Korea is provided mainly for the livelihood protection beneficiary in urban area. The fact that the urban community-centered program is also applied to the livelihood protection beneficiary in rural area brings about some problems in fitness and effectiveness of resource distribution. The purpose of my study is to present my opinion that the public assistance program for the rural community should be put in practice after being fully distinguished from the urban program for the effective distribution of limited social welfare resources to insure the minimum standard of living and seek the self-support contribution which is the purpose of the public assistance program. The subject for this study were livelihood protection beneficiaries living in both rural and urban area. And the study was carried out in this parts: first, the way of life in them, second, the contents of 6 main public assistance programs being carried out. Total number of the livelihood protection beneficiaries are 279 case: 143 case from 15 Dong in 5 cities, and 136 case from 15 Myun in 5 counties. And the social worker who are performing the public assistance programare consisted of 50 case: 25 case from 5 Dong in 5 cities, and 25 case from 5 Myun in 5 counties. This research reach the result that the differentiate performance of the public assistance program in rural community would be an effective device for self-support to be freed from the vicious circle of poverty.

This paper analyzes the relationship between social assistance and poverty in Korea. Social assistance in Korea which had a Poor Law tradition for about forty years, was finally reformed and a new general assistance scheme designed to protect fundamental human rights, was established in 1999. Are the means-tested social assistance benefits effective in protecting the poor from hardship? How effectively do the means-tested benefits reduce poverty? To assess the effects of the means-tested social assistance benefits in Korea on poverty reduction, the study uses household data from the National Basic Livelihood Security Programme Review Board (NRB). Moreover, to obtain a comparative perspective, a British dataset the Family Resources Survey (FRS) is assessed. The incidence and the intensity of poverty for a range of household types are analyzed before and after social assistance benefits for both countries. The results of the analysis show the Korean social assistance benefits do not radically alleviate poverty, although recipients' income positions are improved after social assistance transfers. Compared to Korea, Britain achieved marked success of means-tested social assistance benefits with a high degree of effectiveness, especially among the extreme and the severe poverty brackets, while there are variations between different household types regarding the incidence and the intensity of poverty before and after transfer.

We developed a prediction model of assistance force for the opening/closing of an automobile door depending on the condition of the parking ground. The candidates of the learning models for the operating assistance force were compared to determine the proper force according to the slope and user's force, etc. The reduced experimental model was developed to obtain learning data for the estimation model. The learning algorithm was composed to predict the assistance force to incorporate real assistance force data. Among these algorithms, an Artificial Neural Network (ANN) and Support Vector Machine(SVM) were applied and the adaptability was compared between these models. The SVM provided more adaptability for the learning process of the door assistance force prediction. This paper proposes a system for determining the assistance force to control a door motor to compensate for the deviation of required door force in the slope condition, as needed in the plane condition.

Due to increasing life expectancy, Americans live nearly 20 years after retirement. During this period, elderly persons have to stretch finances to manage the level of living without earnings. However, decision making ability decreases with age. One coping strategy for this problem would be seeking help from others. We examine factors affecting elderly persons' assistance use with respect to financial management using the 2000 Health and Retirement Study (N=3,823). It was found that age, education, health status, and ethnicity significantly affect elderly persons' financial management assistance use. The older-olds, those with lower educational attainment and poorer health status were more likely to use financial management assistance. However, Hispanic elderly were less likely to use financial management assistance.

The aging society comes, the number of the old people expended. Technical aids allow elderly and handicapped people to live independently in their private homes as long as they wish. As a contribution to these required technological solutions, a demonstrator platform for a walking assistance robot. robot which has the capability to perform fetch and carry and various other supporting tasks. In this study, we addresses the development of a walking assistance robot system. We execute static analysis, vibration analysis and flexible dynamics to reserve stability at the design. Each motion of the robot uses a linear actuator and gears. Motion can be distinguished into 3 parts depending on the up & down, rotation, and cushion trans. In each motion, we compare the displacement of the case to be rigid with the case to be flexible. As a result, manufactured and feasibility of the walking assistance robot is validated through preliminary experiments.

Human driver monitoring system is one of the most important systems for the safety in driving vehicles, and therefore driver assistance system has gained much attention during the last decade. This paper proposed an intelligent driver assistance system which monitors human driver's states from bio-signals such as ECG and Blood Pressure. The proposed system used mamdani fuzzy inference to evaluate the driver's mental strain and generated warning signals to the driver. The approach using bio-signals in driver assistance system is the main issue of the related systems and the preliminary results showed the possibility of further research topics in developing more intelligent embedded systems with bio-signal feedback.

Self-efficacy is a major factor related to performance and needs to be improved in business and education field. This study explains the effectiveness of school career assistance to improve college students' self-efficacy. Furthermore, it demonstrates the moderating effects of grit and regulatory focus (promote and prevention). School career assistance is based on group support, and moderating variables in this paper are individual characteristics. In these group and individual dimensions, if the effectiveness of school career assistance varies depending on individual characteristics, schools will be able to establish self-efficacy improvement strategies more appropriate for individual students. School would understand individual characteristics such as grit and regulatory focus, then could make individual strategy for enhancing self-efficacy and performance. Hence, it is expected that the performance of school and student will improve through the self-efficacy improvement plan presented in this study.
