The purpose of this study was to analyze the relationship of the floor classification and the main-living behavior, and the tendency of using furniture and space by surveying the situations of using An-bang space by apartment dwellers. An-bang is a factor that influences on the unit-plan organization, the whole spatial arrangements, and the spatial relation and size, and has the most severe friction between the tradition and western culture. Given seeing the results shown in the main-living behavior by floor type, that the rest and TV watching were shown to be high in terms of a free-standing type can be said that An-bang is more for the individual rest than far the purpose of family harmony. On the other hand, that the family courtesy was shown to be a little higher a sitting-down type, could be understood that the sitting-down style, which is a traditional living mode, is appearing in An-bang.

In today's man's domestic environments, the development of furnishings in their various shapes and functions is as complex as human lives. Architecture, Interior, and Furniture, each one of these have the relationship closer and closer to the direct human environments. In this study, by choosing the theme of sitting , the transformation of man's behavioral models would be examined in sociological terms. By viewing the chair as an emblematic objects made for more than just sitting, the chair has revealed the relations of man with his environment since the history of furnishings began. Qualified architects and designers know that chairs are no longer the objects, but the primary subject of furnishings. Through this examination of the emblematic typologies of periodic chairs in the history of the Western culture, in terms of their relationships with politics , religions, monarchies, societies, and etc., the meaning of the designs could be find and which could be the resolutions for the future innovative design. These refound or recreated meanings in the history of design could create another typology for the future reality.

Recently the exoskeletal power assistive equipment which is a kind of wearable robot has been widely developed to help the human body motion. For the elderly people and patients, however, some limits exist due to the weight and volume of the equipments. As a feasible solution, a tendon-driven exoskeletal power assistive device fur the lower body, and caster walker are proposed in this research. Since the caster walker carries the heavy items, the weight and volume of the wearable exoskeleton are minimized. The key control is used to generate the joint torque required to assist motions such as sitting, standing and walking. Experiments were performed for several motions and the EMG sensors were used to measure the magnitude of assistance. When the motion of sitting down and standing up was compared with and without wearing the proposed device, the $25\%$ assistance was acquired.

We developed a human-sized BWR(biped walking robot) driven by a new actuator based on the ball screw which has high strength and high gear ratio. The robot overcomes the limit of the driving torque of conventional BWRs. Each leg of the robot is composed of three pitch joints and one roll joint. In all, a 10 degree-of-freedom robot with two balancing joints was developed. The BWR was developed to walk autonomously such that it is actuated by small torque motors and is boarded with DC battery and controllers. In the performance test, the BWR performed nice motions of sitting-up and sitting-down. Through the test, we could find capability of high performance in biped-walking.

This paper describes the possibility of evaluating and classifying arthritic pathology using the acoustical analysis of knee joint sound. Six normal subjects and 11 patients with knee problems were enrolled. Patients were divided into the 1st patient group which required an orthopeadic surgery and the 2nd patient group of osteoarthritis. During sitting and standing periods, subjects' active knee flexion and extension were monitored. Fundamental frequency, mean amplitude of pitch, jitter and shimmer were analyzed according to the position. The results demonstrate that the values of fundamental frequency, jitter and shimmer of the 2nd patient group were larger than others and changed unstably. The values of the standing position were larger than the sitting position.

A field study was conducted to assess the preferred height and the range of discomfort recognition of school desks and chairs for students from elementary school to high school. For this study 43 male subjects and 44 female subjects in Taejon metropolitan area were surveyed. The result showed that the preferred height of chairs were found to be about 1.7cm higher than the popliteal sitting height, while the preferred height of desks showed no significant difference with the elbow sitting height which is known to be the ergonomically proper desk height. The threshold value between comfort and discomfort recognition of chair heigth was 1.88cm below the most preferred height and 1.79cm above it. The threshold value between comfort and discomfort recognition of desk height was 1.76cm below the most preferred height and 2.62cm above it.

Healthy adults in the ranges of from 22 to 25 years old, 208 males and 140 females respectively, who have no specific organic diseases in the heart and lung, were experimentally studied on the effect of blood pressure, pulse and breath rates, and blood circulation by the postural changes of the supine, semi-supine, upright, sitting and trendelenburg position. The results obtained were as follows : 1) The blood pressure showed makred differences in the postural changes of the upright>sitting>semisupine>trendelenburg>supine position, orderly. 2) The breath rate did not show specific findings in the postural changes. 3) If the dental chair were suddenly tilted forwardly and backwardly, patients would be subjected to fall in the dangerous state, fainting.

Objectives : The purpose of this study is to report a pediatric patient with five retardations and five flaccidities caused by hydrocephalus treated with oriental medicine. Methods : We performed an ambulatory treatment for him with herb medicine, acupuncture. And we measured grade of sitting, standing, walking, speaking. Results : The child's sitting, standing time increased from zero second to one-two minutes, and speaking improved. Conclusions : We report the good results of oriental medical treatment on this case. And this study requires further studies about five retardations and five flaccidities caused by hydrocephalus.

Physical therapy for patients with Multiple sclerosis, Parkinson's disease, Spinal cord injury. Osteoporosis, CVA and Cerebral Palsy often includes the evaluating and teaching of rolling movements. Motor abilities such as rolling from a supine to a prone position, moving to sitting. getting up on all fours and ultimately standing up from a supine position. represents progression toward physical independence. Rolling is important functional abilities for need to dressing, decubit prevent. bed mobility, neck control, crawling, creeping, sitting, standing and walking. The purposes of this study were to describe motor development concept and rolling task patterns and to approach the therapeutic exercises.
