This paper presents a design and a control of a New Reciprocating Gait Orthosis and dynamic walking simulation for this system. The New Reciprocating Gait Orthosis is distinguished from other one by which has a very light-weight and a new RGO type with servo motors. The gait of a New Reciprocating Gait Orthosis depends on the constrains of mechanical kinematics and initial posture. The stability of dynamic walking is investigated by ZMP(Zero Moment Point) of the New Reciprocating Gait Orthosis. It is designed according to a human wear type and is able to accomodate itself to human environments. The joints of each leg are adopted with a good kinematic characteristics. To test of the analysis of joint kinematic properties, we did the strain stress analysis of dynamic PLS and the study of FEM with a dynamic PLS. It will be expect that the spinal card injury patients are able to train effectively with a Reciprocating Gait Orthosis. The New Reciprocating Gait Orthosis was able to keep smooth walling by the orthotic servo motors and hybrid system, make a sequence of flexion and extension of the joint during the walking. Also, the New Reciprocating Gait Orthosis turned out to be a satisfactory orthosis for walling training, for the spinal cord injury patient.

This purpose of this study was to design the effect of recovering of a hand amputees by Myoelectronic hand. It was designed with 2 degree of freedom in the laboratory. Myoelectronic hand had only one degree of freedom and one movement until now. Also this myoelectronic hand had multi-joint and it could move widely. Wire was used in transmission. Myoelectronic hand data was obtained by analyzing hand anatomically and measuring and that data was applied when it was designed. PID controller of Myoelectronic hand was used to it. Displacement control was applied the first link. Experiment was accomplished in Tip grasp, Power grasp and Hook grasp modes. Displacement control was good in low frequency. Velocity control was applied to each mode. The objective of the study was to develop more better multifunction myoelectronic control strategies. A myoelectronic hand with a hand amputees could do some jobs such as grasping materials, lifting weighting, holding cup and etc. As a result of this study, all subjects with hand amputees significantly improved in ADL. Further studies were needed to evaluate the effect of a myoelectronic hand with more precise laboratory equipment.

The community dance, which is based on the community, started from the concept of the cultural democracy and the dance of the community having a common identity. The members of the community are general citizens. They prepare the space of the mutual understanding actively and share the dance value. The various programs through the art platform such as the program as the cultural art education, the local culture reinvention program, the residence space conjugation program, the citizen culture vitalization program and etc. are performed in our country and now ask for the program of the humanities access. The activation plans of community dance are as follows: 1. A curriculum for the professional training for community dance needs to be developed in the university and civic level. 2. It is continued with the cultural art policy, and its support system has to be followed. 3. The community dance expert has to be institutionally guaranteed as the culture welfare worker.

Recently Car-maker has improved efficiency of engine because customers prefer car with increased fuel efficiency For this reason, PTC heater has been applied with diesel engine since past 10 year for heating performance. Furthermore heat source continually reduced in Gasoline engine because of improvement of gasoline engine efficiency. So PTC heater is also applied to Gasoline engine. Recently trend is to increase using of PTC heater. Like this PTC heater of auxiliary heater has been transformed into the main heater. But PTC heater has increasing HVAC package. Also, PTC heater has increasing temperature distribution and decreasing heating performance because cold air is bypassed. This paper is about studying hybrid PTC heater that is improved about disadvantages of PTC heater. Hybrid PTC heater is composed of an efficiently combination of thin PTC heater with coolant heater core. This paper presents experimental results of heating performance test at vehicle level. As a result, Hybrid PTC heater could improve interior temperature of vehicle about 0.9℃~3℃

HVAC System is currently used for controlling of vehicle cabin temperature and mode. We are usually using semicenter type HVAC System. But semi-center type HVAC System has more package problem than center mount’g type HVAC System. This being so, when developing a new car, one of the repeated problems is the lack of storage space. In particular, the small size of the glove box is one of the biggest requirements from the consumer. In this study, optimizing center mount’g type HVAC System, could be decreased size, cost and weight. Additionally we could improve N.V.H(Noise, Vibration, Harshness) performance. We used DFSS method and made 18 variations of aspirators by L.I.S rectangular coordinate system. Also CFD analysis tool used FLUENT.

In this study, Experiments on compartment air flow are carried out on condition of forced ventilation and natural ventilation by using the laser visualization method. Targeted models are HKMC’s vehicles and their competitive ones. Experiments on 4door vehicle have performed changing and improving influence factor of ventilation performance and evaluated resulting values; Fogging generation performance, Defrosting performance and compartment static pressure. As a result of laser visualization, ‘air extractor grille’ and ‘rear package tray & rear glass gap’ have proven to be major factor deciding compartment air flow. Also, in case that air extractor grille was chosen among improvement factors and adopted two ones, we could achieve best results in tests on fogging generation performance, Defrosting performance, Compartment static pressure
