Objective : To evaluate the sensory processing ability in relation to parenting stress and find the sensory modulation areas affecting the parenting stress in disabled children Methods : Parents of 124 children with disabilities between 3 to 7 years receiving occupational therapy in Seoul and Gyeonggi-do made out the questionnaire and in items of questionnaire, Short Sensory Profile and Parenting Stress Index of short form was included. Results : Among general information, parenting stress of parents had significant correlation with the degree of disability and correlation with the lower level 2 of Parenting Stress Index. The more sensory processing disability was increased, the more parenting stress was increased. Parenting stress showed the significant correlation with movement sensitivity area and under-responsiveness/behaivor area seeking specific stimulation among sensory processing areas and had significant correlation with tactile sensitivity and auditory filtering. Sensory processing areas which affect the most the Parenting Stress were movement sensitivity and under-responsiveness/behaivor area seeking the specific behavior among sensory control disabilities. Conclusion : The parenting stress of parents with the disabled children had the correlation with sensory processing ability. The difficulty of sensory processing increased the parenting stress. Hence, in order to improve children's sensory processing ability, the appropriately coping program should be developed and the appropriate intervention for improvement of sensory processing ability of children will be necessary.

In this study, the control method of assistive robot was developed for the elderly. The control method of gait-assistant-robot was proposed considering the change of COP (Center of Pelves), BOS (Base of Support) and comparative analysis of the moving velocity for the elderly. We analyzed the movement of COP of the body and its velocity of the elderly equipped with manual walker and gait-assistant-robot. As a result, change in COP was greater from left to right than from anterior to posterior; also, the average velocity of the movement of COP and manual walker for manual walker gait was 0.7(m/s). Therefore, it is necessary to concern more on the left-right balance and synchronization of the velocity of COP.

A comprehensive investigation of the stochastic response of an isolated cable-stayed bridge subjected to spatially varying earthquake ground motion is performed. In this study, the Jindo Bridge built in South Korea is chosen as a numerical example. The bridge deck is assumed to be continuous from one end to the other end. The vertical movement of the stiffening girder is restrained and freedom of rotational movement on the transverse axis is provided for all piers and abutments. The longitudinal restraint is provided at the mainland pier. The A-frame towers are fixed at the base. To implement the base isolation procedure, the double concave friction pendulum bearings are placed at each of the four support points of the deck. Thus, the deck of the cable-stayed bridge is isolated from the towers using the double concave friction pendulum bearings which are sliding devices that utilize two spherical concave surfaces. The spatially varying earthquake ground motion is characterized by the incoherence and wave-passage effects. Mean of maximum response values obtained from the spatially varying earthquake ground motion case are compared for the isolated and non-isolated bridge models. It is pointed out that the base isolation of the considered cable-stayed bridge model subjected to the spatially varying earthquake ground motion significantly underestimates the deck and the tower responses.

The following thesis has been composed with the inspiration attained from Paul Ardenne's conception on Contextual Art. In Europe and in the United States, there is a group of artists who emphasize in the importance of artist's participation in social, political, economical, environmental and moral issues. Since the 1960's, these artists have pondered on Modernism's ideas where art is contextually separated from humanly issues whereas the manners of such artists put on emphasis in the intent to participate in the real human social and ethical issues. Forerunner in this field of art such as Wolfgang Leib display hybrid or meta style in their work. His work displays a quadrilateral form of pollen which represents the simultaneous blending of two mixed ideas such as the abstract from the real. Thus heterogeneous style and philosophy which includes a range of medias and today's trend is observed in Contextual Art. Such art form is also found in landscapes where it is not seen as an observable object but rather an interactive object. It is correlated to Arte Povera of the Italian Art Movement, Support-Surface of the French Art Movement and lastly to the Fluxus. Through these art movements, we find a mutual antipathy towards putting art for sales in the capitalism market and reflect the social role of art in postmodern era.

Since the discovery of the muscle spindle by Hassall (1831), an intensive studies of its anatomical and physiological characteristics had been undertaken. Recent morphological studies of Boyd (1962) demonstrated that the muscle spindles have two different intrafusal muscle fibers, nuclear bag and nuclear chain fiber, and these intrafusal fibers are under independent motor innervation by ${\gamma}_1$ and ${\gamma}_2$ motor neurone. Neurophysiological studies of Hunt and Kuffler (1951) showed regulatory effect of ${\gamma}$ motor neurone upon the excitability of the spindle afferents. Harvey and Mathews (1961) observed the dynamic and static characteristics of the two different spindle afferents, the primary and secondary ending. Furthermore, Mathews (1962) postulated the functional existance of two kind of ${\gamma}$ motor neurones, namely, the dynamic and static fusimotor fiber. Recent report of Kim and Partridge(1969) pointed out that the descending vestibular signals had increased the slope of the length-tension relationship in stretch reflex; Kim (1967) demonstrated that the descending vestibular impulses act upon the stretch reflex loop through the ${\gamma}$ motor pathway. These experimental evidences from the morphological and neurophysiological studies on the muscle spindles support the concept that the stretch reflex action of the skeletal muscle operates as a negative feedback control system. The author had discussed the way by which the f system participates in the control of stretch relfex feed back system. that was taken for a prototype of posture and movement.

Several mobility supporting protocols have been proposed across OSI reference layers. Each protocol has similar or different characteristics based on its operating layer which affect a handover latency. In this paper, we analyze handover performance of most representative protocols in each layer. For analysis, we use SUBNET model based Markovian model and movement model. In result, difference of protocol handover latency is not occurred by DAD but also by security, movement detection, message processing time.

This paper presents improper use of latex-elastic ring in movement of teeth and its consequence. Simple orthodontic movement of teeth including closure of diastema may be achieved by the use of simple method with fixed or removable appliance associated with latex-elastic ring. But, if it is used alone, it acts as a local irritant and then produces localized periodontitis. In case of localized periodontitis resulting from latex-elastic ring, diagnosis is difficult because the patient is usually unaware of the presence of the rings on the roots of the involved teeth and because the ring is not probed and is radiolucent and therefore not discernible radiographically and clinically. Occasionally, surgery is requred for the detection. This case emphasizes the necessity that the use of latex-elastic ring in closing diastema should be accompanied with removable or fixed appliance as well as close professional supervision. Its use without adequate provision for stabilization or retention on the crowns of teeth results in destruction of periodontal support and the teeth may be lost.

Wandering behavior is a serious problem among the elderly in nursing homes, yet it has received relatively little study by those interested in gerontology. The research that has been done has generally regarded wandering behavior as an aimless, directionless movement. Only a few studies have addressed the problem after first assuming that wanderers have a goal to their movement, and fewer still have explored the role of the physical environment on the wanderer's behavior. None have combined the two approaches. In this paper, the physical environment will be looked at for support of the theory of wandering as a goal seeking behavior. In a pilot study using behavior maps, the movements of wanderers and non-wanderers are analyzed and compared for the amount of visual access and exposure their locations contain. While the behavioral implications of these two measurements are considered, the limitations of the results are also discussed, so that their relationship to the cause of wandering behavior may be better understood. By implying that wandering is not a totally aimless but purposeful behavior at least in the subconscious level, constructive design implications can be suggested that would make wandering a more pleasant experience for the wanderer and increase the ease of the nursing home staffs management of the problem.

This paper aims to explore the relationship between the quality of the audit and the level of stock return co-movement in the context of the Vietnamese emerging market. The empirical study is designed based on the quatitative method and deductive approach. The panel dataset includes 256 listed firms from different industries,with 1115 firm-year observations on Ho Chi Minh City Stock Exchange for the period from 2014 to 2018. In the research, we built the econometric regression model, using stock return synchronicity and audit quality as the dependent and independent variable, respectively. Some control variables are also added to the econometric regression models as they are well-documented in prior research to have an effect on stock price synchronicity. To improve the accuracy of the regression coefficients, beside the Ordinary Least Squares, we employ the Random Effects Model and the Fixed Effects Model for better statistical analysis of panel data set. The results show that the quality of the audit is positively correlated to stock price synchronicity. This finding suggests that stock returns of companies with higher quality of the audit are more synchronous with the market. Results for other control variables also support our reasoning for the main findings.

Conventionally, 2WS is used for vehicle steering, which can only steering front wheel. In case of trying to high speed lane change or cornering through this kind of vehicle equipped 2WS, it may occur much of Yaw moment. On the other hand, 4WS makes decreasing of Yawing Moment, outstandingly, so it is possible to support vehicle movement stable. And conventional ABS and TCS can only possible to control the longitudinal movement of braking equipment and drive which can only available to control of longitudinal direction. There after new braking system ESP was developed, which controls both of longitudinal and lateral, with adding of the function of controlling Active Yaw Moment. On this paper, we show about not only designing of improved braking and steering system through establishing of the integrated control system design of 4WS and ESP but also designing of the system contribute to precautious for advanced vehicle stability problem.
