Currently, in Korea, the number of handicapped children receiving inclusive education in general schools is expanding. In the inclusive education field, the most important tasks are personal needs support, such as toilet assistance, meal assitance, and support for wearing and taking off various assistive devices. A significant portion of the support work in the actual education field is related to clothing. Therefore, it is necessary to research and develop universal fashion designs for handicapped children at school where inclusive education is implemented. To achieve this aim, this study analyzed the concepts, principles and, characteristics of universal fashion design through theoretical research and established research principles. In this study, two fact-finding surveys were conducted. Next, a total of 10 universal fashion designs were proposed considering both the preceding survey results and the principles of universal fashion design Among them, the four designs that were considered most suitable were selected for universal fashion design through F.G.I (Focus Group Interview) analysis conducted by experts. The four selected designs were made by referring to the size framework based on the '6th Human Body Size Survey Report of Korea'. The completed experimental clothes were proposed as the final universal fashion design for handicapped children by conducting external evaluation through a virtual clothing system and real clothes.

The purpose of this study is to examine the legal attribute of subsidiarity principle on the National Basic Livelihood Security Act. The principle of subsidiarity is applied to the regulation for 'fundamental principle of benefits' on the National Basic Livelihood Security Act, therefore it functions as legal theory. However, due to its both positive and negative characteristics it becomes to be interpreted and applied in a different meaning depending on the normative characteristics of related laws. In brief, as the passive meaning of subsidiarity principle guarantees the freedom of civilian by limiting national power, it is reasonable in social control norm like criminal law. However, as nation's active role of intervention and support is required in order to protect basic standard of human life according to the principle of Social(welfare)State, the active meaning of subsidiarity principle is reasonable in Social Security law, especially in public assistance. Hence, the principle of subsidiarity on the National Basic Livelihood Security Act becomes to realize, justice, goal fitness and legal stability when it is operated by system with interpreting in an active meaning.

In this paper, we designed and tested an ankle joint mechanism for a gait rehabilitation robot. Gait rehabilitation programs are designed to improve the natural leg motion of patients who have lost their walking capabilities by accident or disease. Strengthening the muscles of the lower-limbs and stimulation of the nervous system corresponding to walking helps patients to walk again using gait assistive devices. It is an obvious requirement that the rehabilitation system's motion should be similar to and as natural as the normal gait. However, the system being used for gait rehabilitation does not pay much attention to ankle joints, which play an important role in correct walking as the motion of the ankle should reflect the movement of the center of gravity (COG) of the body. Consequently, we have designed an ankle mechanism that ensures the safety of the patient as well as efficient gait training. Also, even patients with low leg muscle strength are able to operate the ankle joint due to the direct-drive mechanism without a reducer. This safety feature prevents any possible adverse load on the human ankle. The additional degree of freedom for the roll motion achieves a gait pattern which is similar to the normal gait and with a greater degree of comfort.

In FMS (Flexible Manufacturing System) and CIM (Computer Integrated Manufacturing), machine-tools have been the target of integration in the last three decades. The conventional concept of integration is being changed into the autonomous manufacturing device based on the knowledge evolution by applying advanced information technology in which an open architecture controller, high-speed network and internet technology are included. In the advanced environment, the machine-tools is not the target of integration anymore, but has been the key subject of cooperation. In the near future, machine-tools will be more improved in the form of a knowledge-evolutionary intelligent device. The final goal of this study is to develop an intelligent machine having knowledge-evolution capability and a management system based on internet operability. The knowledge-evolutionary intelligent machine-tools is expected to gather knowledge autonomically, by producing knowledge, understanding knowledge, reasoning knowledge, making a new decision, dialoguing with other machines, etc. The concept of the knowledge-evolutionary intelligent machine is originated from the machine control being operated by human experts' sense, dialogue and decision. The structure of knowledge evolution in M2M (Machine to Machine) and the scheme for a dialogue agent among agent-based modules such as a sensory agent, a dialogue agent and an expert system (decision support agent) are presented in this paper, with intent to develop the knowledge-evolutionary machine-tools. The dialogue agent functions as an interface for inter-machine cooperation. To design the dialogue agent module in an M2M environment, FIPA (Foundation of Intelligent Physical Agent) standard platform and the ping agent based on FIPA are analyzed in this study. In addition, the dialogue agent is designed and applied to recommend cutting conditions and thermal error compensation in a tapping machine. The knowledge-evolutionary machine-tools are expected easily implemented on the basis of this study and shows a good assistance to sensory and decision support agents.

The research of occupational injury for safety and health is a comparatively recent occurrence. As labor activities took place regarding to employee concerns in industrial uprising, human resources health was tried to enhanced as a labor safety subject. Noticing that traditional statistics approach has limitations in learning future forecasting and major factors causing occupational injuries in each industry, Korean Government initiated a quantitative systematic simulation model project to analyze how the annual injury rate has been dropped and stays in a level for recent years. From this motivation and the project, system dynamics models have been developed to explain the mechanisms for reducing annual injury rate, and the mechanisms quantitatively. The main cause effects for the reduction of annual injury rate were due to the government driven investment on safety facilities. In overall viewpoint the gain achievable from these efforts has been reached a saturated level. However, it could reduce the annual injury rate if you chose the industry and size carefully. The model for forecasting, major injury factors, safety budget and allocation are introduced and analyzed, and Analyzing occupational injury related factors can also reduce employee injury and disease related costs, including medical care, quit, and disability assistance costs.
