  • Computer simulations and test trials were carried out to obtain the optimal stamping conditions of the die design of the laser welded automotive body. The stamping process including gravity deflection bead calibration binder wrap, forming and spring back was simulated and compared with the results obtained from test trials. The production variables were determined from a preliminary operation and they were investigated in the simulation and the test trials. The formability was tested under the various conditions, such as the initial position of blank, blank holding force, corner radius and the shape of drawbead. Sound products without fracture, wrinkling and excessive weldline movement were produced by applying results obtained this investigation.

  • The bogie of Rolling Stock is the basic rolling component. It operates the train body, guides the body considering various tracks and offers comfort to passengers. We can verify the safety level of bogie about all factors through the first -grade scenario of Preliminary Hazard Analysis, but especially the horizontal acceleration sensor, equipped in each power bogie and trailer bogie, is the device, which makes it possible to test bogie instability and uncomfortable body movements by the method, similar to actual train driving, and in this context the necessity of this device becomes important. This paper would classify the main functions of driving sub system and examine the reliability, availability, maintainability and safety, which are main factors of RAMS. Especially, we would realize the bogie instability sensor with a simulator and offer the content in analyzing the data by the statistical method, which are obtained through the connected test with OBCS.

  • Cranio sacral therapy is a refinend and subtle type of osteopathic treatment that encourages the realease of stresses and tentions throughout the body, including the head. Cranio sacral therapy is trained to feel a very subtle, rhythmical shape change that is present in all tissue. This is called Involuntary Motion or Cranial Rhythm. The movement is of very small amplitude therefore it takes practitioners with a very finely developed sense of touch to feel it. This Rhythm was first described in the early 1900's by Dr. William G. Sutherland and its existence was confirmed in laboratory tests in the 1960's and 1970's. Tension in the body disrupts the cranial rhythm. This shows them what stresses and strains your body is under a present and what tentions it may be carrying as a result of its past history.

  • The purpose of this study is to provide definition of proprioception, foundations and roles of neuroanatomy, and systemical review of proprioceptive activities in sensory integration intervention. Proprioception exists in muscle, ligaments, joints and skin and it plays important role in controling body movements and interacting with environment during child development. Proprioception interacting with tactile and vestibular systems contributes to the change of muscle tone, postural control, refinements of planning and praxis. Children who are deficit in proprioceptive processing would seek hypo-responsive proprioceptive input or avoid hyperactive one. Outcome of poor proprioceptive input would cause the problems of praxis and postural control. Because proprioception provides information about the position and movement of body and limb it is important for development of body scheme and motor planning. It also influences the arousal and emotional tone. Sensory integration intervention which provides rich proprioceptive activities will improve the level of arousal and enhance motor planning.

  • Small overlap crash caused fatal injury in real-world crash. IIHS(Insurance Institute for Highway Safety) proposed the small overlap test. The objective of this study is to analyze dummy injury criteria and dummy excursion on the sled reinforced body angle. Result of the comparisons of dummy injury criteria of a head, neck, and chest was best correlation between sled and vehicle test on base $angle+3^{\circ}$. However, lower extremity was not correlation because sled test could not copy of intrusion. There were a correlation between dummy movement and sled reinforced body angle. Sled reinforced body angle affects the lateral direction of excursion more than longitudinal excursion.

  • Purpose : The purpose of this study was to examine the effects of PNF of irradiation using an indirect treatment of the stroke patient's static weight support and walking speed. Methods : Was carried out a total of nine different the PNF method of treatment for patients with left hemiplegia stroke. PNF of treatment is not in the non-paralyzed side of the trunk and upper and lower extremities by applying resistance and increased strength of the affected side. Assessment of treatment weight support both feet measured and modified using the timed up and go test were compared before and after treatment. Results : Treatment of the paralyzed side of the quadriceps and hamstring, gluteus medius muscle strength increased, and both sides of the foot body weight support improved walking speed was increased. Conclusion : Irradiation using PNF indirect treatment improves the function of the gait of stroke patients.

  • This paper presents channel measurements for wireless body area network(WBAN) and provides performance evaluation from the measurement. We measured the radio propagation in 2.45 GHz ISM band in an anechoic chamber according to various human movements and the position of transmit antennas. Two transmit antennas are mounted on different positions of human body for the purpose of comparing the diversity gain and correlation between the channels in $2{\times}1$ multiple-input single-output(MISO) systems. The experimental results show that the outage capacity is closely related with the correlation coefficient between channels in transmit diversity system.

  • Purpose:In this study is to verify the effects postural control training based on Bobath approach for body schema and visual perception on Middle Cerebral Artery(MCA) Infarcts. Methods:The subject was a 46 years old man with MCA infaction, lives in B city. An AB design for a single-subject research was used for this study. The procedures consisted of 1 time of baseline phase(A), 20 times of treatment phase(B). We applied the Bobath approach at the subject. Treatments included to facilitate trunk alignment and stability, and to train weight bearing and shifting, to facilitate pelvis movement, and to train walk especially stance phase and assist up-down stairs locomotion in environment similar to actual daily life. Results:With this treatment, the majority of body schema and visual perception and postural control was improved in treatment phase compared with in baseline phase. Therefore, this study supported the effectiveness of postural control training based on Bobath approach for body sechma and visual perception of hemiplegia. Conculusion:This study is integrated postural control training with Bobath approach that are widespread for hemiplegia and measured outcomes based on individualized therapy goals. Consequently the study is suggested the meaning of quality effectiveness of Bobath approach.
