A control of the body posture and movement is maintained by the vestibular system, vision, and proprioceptors. Afferent signals from those receptors are transmitted to the vestibular nuclear complex, and the efferent signals from the vestibular nuclear complex control the eye movement and skeletal muscle contract. The postural disturbance caused by loss of the vestibular function results in nausea, vomiting, vertigo and loss of craving for life. The purpose of this study is to develop a off-vertical rotatory system for evaluating the function of semicircular canals and otolith organs, selectively, and visual stimulation system for- stimulation with horizontal, vortical and 3D patterns. The Off-vortical axis rotator is composed of a comportable chair, a DC servo-motor with reducer and a tilting table controlled by PMSM. And a double feedback loop system containing a velocity feedback loop and a position feedback loop is applied to the servo controlled rotatory chair system. Horizontal, vertical, and 3D patterns of the visual stimulation for applying head mounted display are developed. And wireless portable systems for optokinetic stimulation and recording system of the eye movement is also constructed. The gain, phase, and symmetry is obtained from analysis of the eye movement induced by vestibular and visual stimulation. Detailed data were described.

A control of the body posture and movement is maintained by the vestibular system, vision, and proprioceptors. Especially, vestibular system has a very important function that controls the eye movement through vestibuloocular reflex and contraction of skeletal muscles through vestibulospinal reflex. However, postural disturbance caused by loss of vestibular function results in nausea, vomiting, vertigo and loss of craving for life. Lose of vestibular function leads to abnormal reflex of eye movements named nystagmus. Analysis of the nystagmus is needed to diagnose the vertigo, which is performed by means of electrooculography(EOG). The purpose of this study is to develop a computerized system for data processing and an algorithm for the automatic evaluation of the slow component velocity(SCV) of nystagmus induced by optokinetic(OKN) stimulation system. A new algorithm using recursive least square method(RLSM) to detect SCV of nystagmus is suggested in this paper. This method allows a fast and precise evaluation of the nystagmus, through artifact rejection techniques. The results are depicted in this paper.

Aesthetic Movement is an artistic movement which intended to bring up the quality by implanting beauty in everyday life. Aesthetic movement made the beauty itself come alive within each person and thus made it possible to improve the quality of life. Aesthetic Movement emphasized the total artistic concept and this brought new wave to the textile design movement. This paper is the study on the Aesthetisism and the effect that had on the textile design. This study draws the conclusion that there are four areas the textile designs of that era was influcenced by : Firstly , through the influence of the Japanese art, the textile designs came to have 2 dimensional quality. Secondly, through the influence of the pre Raphaelite, colors in the textile designs changed to have pale tones. Thirdly, with the influence of William Morris, the creativity in textile design came to be alive. Forthly, to better the quality of life and design, the cooperative spirits of Arthur Liberty, Morris, Godwin, Lewis Days and other designers, architects including artists contributed a great deal to make the English textile designs to be creative contemproary art works.

The aim of this study was to determine the prevalence of self-assessment halitosis and to offer the basic information that establishes a strategy of effective health promotion and to enhance the quality of life. This study performed a questionnaire survey. The questionnaire was filled out by the 362 adults, who lived in Incheon Metropolitan City from May to July, 2010. The data were analyzed using a Chi-square test in the SPSS version 12.0 program. The prevalence rate of self-assessment halitosis was 24.3%. Hypertension, diabetes, medication and inadequate oral hygiene practice were significantly associated with self-assessment halitosis. Other factors of self-assessment halitosis were older age and occupation. As a result, dental professionals have to investigate a systemic disease history thoroughly. And they have to educate regular checkup of oral health and to perform a continuous feedback. The self-assessment halitosis has a negative influence on mental health and social life, so dental professionals must take into consideration about the halitosis.

Community recently pays attention to participation, network, and partnership of local residents and community stakeholders for the purpose of solving community problems and issues. This is the typical characteristics of local governance as an institutional setting to solve the problems which communities face with. The aim of this study is to attempt an analysis of local governance from the perspective of community welfare. To do that, it especially focuses on 'Gwangju Greenway' as a case. Participation of and communications among local residents strengthen their community's capabilities to deal with problems and seek better solutions. Above all, networking and cooperation between local government and local residents are required to improve the quality of local residents' participation at the process of planning and policy-making in the area of community welfare. 'Gwangju Greenway' is a good example of community welfare in that local residents actively seek to solve their own problems and realize common good within their local community through the improvement of social interaction and solidarity among local residents, thus resulting in good quality of life.

Assuming that Smart Work will have a positive effect on job satisfaction, and which, in turn, will improve productivity, domestic and international organizations have adopted and implemented Smart Work. However, leading companies have recently reduced or shut down operations of Smart Work. If Smart Work had really brought about the improvement of productivity, there would be no reason for organizations to take such action. Therefore, this paper reviews the relationship among Smart Work, job satisfaction and productivity. Based on the National Digital Science Library (NDSL) database, we select eight references related to Smart Work, and analyze them systematically. The previous empirical studies show that Smart Work produces a positive outcome for job satisfaction, which, in turn, improves productivity. However, we find that the previous research has a problem demonstrating the relationship between job satisfaction and productivity, because they has unclearly measured the concept of job satisfaction. This research deeply discuss this issue, and provides future research direction.

This is the one concept of the Korea paintings which defines the korea Art sprite. The line of korea painting is very important. It is impressions, korea artist had mastered the difficult art line of representing movement. That offers the important motive, that is discovery of Identity. this korea painting's line is like to meditation. To meditate is to think and ponder about the same holy truth for many hours on end, to fix an idea in one's mind and to look at it from all sides without letting go of it. That is the purpose behind the greatest of the korean landscape paintings Futhermore that is the purpose Shui-Mo paintings. This is the most important. What the korean value most highly in art. There is something wonderful in this restraint of Korea art, in its deliberate limitation to a few simple motifs of nature. But today, anyone did not interested in this motif. So that Shui-Mo paintings did not concerned too. Therefore, we consider it childish to look for details in pictures and then to compare them with the real world. We masters to acquire such a facility in the handling of brush and ink that write down their vision while their inspiration was still fresh.

This study examines the effects of coping resources on life satisfaction of middle and older caregivers looking after family members with activities of daily living disabilities. Personal resources and socio-relational resources were included as predictors after controlling for demographic characteristics. We studied 154 middle and 132 older adults drawn from the Korean Longitudinal Study of Ageing (KLoSA). The multiple regression results of this study were as follows. First, subjective health and family satisfaction had significant effects on middle-aged caregivers' life satisfaction. Specifically higher levels of subjective health and better relationships with their family predicted higher levels of life satisfaction. Second, cognitive function, household income, and family satisfaction had significant effects on middle-aged caregivers' life satisfaction. Higher household incomes, higher levels of cognitive function, and better relationships with family predicted higher levels of life satisfaction. For both middle and older adults, the effect size of family satisfaction was the largest out of all coping resources. The results revealed discrepancies regarding the importance of coping resources between middle and older caregivers, implying that developing interventions for middle and older caregivers (in accordance with their need for coping resources) is necessary. The results also indicated that having good relationships with one's family was the most important factor for both middle aged and older caregivers' life satisfaction. The results suggest that policies or services focused on endorsing healthy family relationships should be developed to improve the life satisfaction of caregivers.
