Purpose: This study investigated various factors relatied to wandering behavior of Korean elders with dementia (KED). Methods: A sample of 160 ambulatory residents with dementia from 14 long term care facilities was used to examine demographic, individual, cognitive, physical health, and environmental characteristics by comparing wanderers (N=108) to nonwanders (N=52). Subjects were evaluated by Korean versions of the Mini-mental State Exam (K-MMSE), the Physical and Instrumental Activities of Daily Living (K-PIADL), and the Revised Algase Wandering Scale Nursing Home version (KRAWS-NH) along its six dimensions. Demographic and environmental data were also obtained. Independent sample t-tests, Chi-square test, Fisher's Exact tests, and ANCOVAs were used to examine differences between wanderers and nonwanders. Results: Wanderers were significantly (p<.05) older and had more limitations in K-PADL and K-IADL. The degree of overall wandering and certain features of wandering were significantly different (p<.05) by total number of residents in the facility, type of bedroom (i.e., "Ondol"), and color of bedroom and living-room walls (i.e., sky blue). Conclusions: Findings of this study may be useful in understanding wandering behavior of KEDs and thus developing more culturally specific management strategies.

Subsequent to major changes in workplace such as communication method, uncertain organizational environment, and globalizaiton, several studies in workplace have explored the effects of those changes on work outcomes. Especially, employees need to have the balance in working alone and working with others. The purpose of this study is to examine the effects of control over the physical environment by individuals and the effects of flexibility on individual and group work outcomes in the workplace, to examine the effects of distraction on work outcomes, and to suggest a interrelationships among variables. In this study, four hundred and nine questionnaires were collected from employees of three manufacturing corporations in Michigan, U. S. In order to explore the causal interferences among multiple relationships suggested in this study, path analysis was employed using Lisrel 8.54. The results indicated that control over the physical environmental features of the workplace positively influenced job satisfaction. The findings also supported the hypothesis that flexibility is positively related to task group cohesiveness. It was found that distraction was negatively associated with control and flexibility. However, it was not supported that control was positively associated with perceived performance. This study found control and flexibility in the workplace to be important. Some practical implications were suggested emphasizing that control and flexibility allow limited resources to be used in ways that permit individuals to work effectively within a changing work environment.

The purpose of this study was to analyze the environmental privacy on the perspective of integration and segregation of spatial areas in facilities for the elderly, through investigating required environmental privacy at each hierarchical space, the contextual situation and counterplan for the privacy. For the study, a content analysis for 35 foreign academic journal articles published from 1990 to August of 2013 was conducted. The results of the study were as follows: First, four hierarchical spaces had somewhat integrated characteristics as being required various types of privacy beyond the original features of each space. Especially semi-public and public spaces were needed the privacy similar to in private or semi-private areas. Second, the contextual situation for the privacy was mainly from undesirable access and psychological pressure of other residents, staff and etc. to the residents' personal space, stuff, and behaviors. The other was from no space (no sitting) or no equipments for privacy. Third, the counterplan for privacy was categorized as improvements of physical environments and making defensible space or keeping physical distance of the elderly. It is suggested that welfare of the aged act in Korea about the room capacity for the elderly facilities needs to be reconsidered for the privacy in their individual rooms and the privacy in semi-public and public area must be considered to make the behavior scope of the elderly extended.

In this talk we outline the current understanding of solar flares, mainly focusing on magnetohydrodynamic (MHD) processes. A flare causes plasma heating, mass ejection, and particle acceleration which generates high-energy particles. The key physical processes producing a flare are: the emergence of magnetic field from the solar interior to the solar atmosphere (flux emergence), formation of current-concentrated areas (current sheets) in the corona, and magnetic reconnection proceeding in a current sheet to cause shock heating, mass ejection, and particle acceleration. A flare starts with the dissipation of electric currents in the corona, followed by various dynamic processes that affect lower atmosphere such as the chromosphere and photosphere. In order to understand the physical mechanism for producing a flare, theoretical modeling has been develops, where numerical simulation is a strong tool in that it can reproduce the time-dependent, nonlinear evolution of a flare. In this talk we review various models of a flare proposed so far, explaining key features of individual models. We introduce the general properties of flares by referring observational results, then discuss the processes of energy build-up, release, and transport, all of which are responsible for a flare. We will come to a concluding viewpoint that flares are the manifestation of the recovering and ejecting processes of a global magnetic flux tube in the solar atmosphere, which has been disrupted via interaction with convective plasma while rising through the convection zone.

Traumatic occlusion is a morbid condition that is caused by repeated occlusal stresses exerted on the periodontium that exceed the physiologic limits of tissue tolerance and contribute to the breakdown of the supporting tissue of the teeth. In reviewing these cases, the authors obtained the following results. 1. Roentgenographic examination revealed the typical signs of traumatic occlusion: severe resorption of roots, destruction of alveolar bone. 2. The major factor of traumatic occlusion is abnormal occlusal force. 3. The rsorptions of roots and periodontal changes which are caused by traumatic occlusion depend on the individual variation of the physical potential. 4. The pathologic features of traumatism are basically different from those of inflammation.

This paper presents a decentralized coordination for a small-scale mobile robot teams performing a task through cooperation. Robot teams are required to generate and maintain various geometric patterns adapting to an environment and/or a task in many cooperative applications. In particular, all robots must continue to strive toward achieving the team's mission even if some members fail to perform their role. Toward this end, given the number of robots in a team, an effective coordination is investigated for decentralized formation control strategies. Specifically, all members are required first to reach agreement on their coordinate system and have an identifier (ID) for role assignment in a self-organizing way. Then, employing IDs on individual robots within a common coordinate system, a decentralized neighbor-referenced formation control is realized to generate, keep, and switch between different geometric shapes. This approach is verified using an in-house simulator and physical mobile robots. We detail and evaluate the formation control approach, whose common features include self-organization, robustness, and flexibility.

Focused on the performance of interactivity in the appreciation of media art, this study is associated with the continually changed art texts and a participator's physical reactions to savor the art. Digital works of art emphasizing interactivity usually decentralize and disperse the responsibility and the central role for creating and producing the art works. Proper procedure of the work is generated by actions such as clicking the mouse, controlling the joy stick or actual movement of anticipators' bodies. The art works are influenced by participators' interactivity, which makes the leading roles and the responsibility for creating art scattered and divided. These features are similar with those of the 'Rhizome' which Gilles Deleuze(1925~1995) and Felix Guattari(1930~1992) have discussed. In their argument, 'Rhizome' is an interval or being 'between', which keeps changing. 'Rhizome' is a state in which the individual and the work of art never reach the conclusion, only a phenomenon of eternally altering. Like 'Rhizome', this sort of art work has the decentralized system, opens for several directions, and activates the system which is changeable as linked items increased or decreased. These works stimulate the individual to perform and act while appreciating the art piece. In terms of processing and preceeding, interactivity is the important equipment and catalyzer. Through these procedures, the pieces can be the 'floating work of art' combined and condensed with the whole participators' reactions. The 'floating work of art' is neither the expression of an individual nor that of one particular group. Multidimensional influence of the web is the web which is constantly reorganizing and producing in its connective state. This connective state is activated by interactivity. The Rhizomatic system embodies the floating work of art process. Due to each individual perceiving art in individualistic terms, there is no dominating powers or central points. I regard this art works possessing above traits as the work of art with Rhizomatic system. The work of art with the Rhizomatic system is embodied through interactivity and because physical action activates the process of appreciation, a participator can actually experience and practice the philosophy. Ultimately the Rhizomatic speculation occurs during the interactivity of appreciating the Rhizomatic art pieces. The Rhizomatic system penetrates into the intuitive area beyond our recognition and thoughts, as we are engaged in the connective process. With the methods and manners of interactive art, we can possibly reconsider the system as a tool in which the participator is directly able to link experience and theory to the philosophies of Deleuze and Guattari.

The purpose of this study was to investigate the physical characteristics and instrumental activities of daily living(IADL) of the elderly (85+). The subjects were three-hundred elderly people over the age of 85, living in Kyungpook Sung-Ju area who have no problems in daily living. The survey on anthropometric measures and IADL were carried out by individual measurement and interviews using measuring devices and questionnaires. The subject group of the study was composed of 27% males and 73% females, the average age being 87 years old. Notable physical features of the subjects include considerably short statues and small physiques compared to the average Korean elder. The mean Body Mass Index(BMI) was 20.9. The average percentage of body fat in male and female was 21.7% and 29.5% respectively, and the average waist/hip ratio(WHR) was 0.9 and 0.85 respectively. The percentage of the subjects who were able to perform all the IADL was 51% in males and 25% in females. The male subjects were more capable than the females in all the IADL except for preparing meals. BMI showed positive correlations withy weight(r=699), WHR(r=0.157), body fat percentage(r=0.57), lean body mass(r=0368) and total body water(r=0.368). WHR also had positive correlation with weight(r=0.184), BMI(r=0.157), lean body mass(r=0.149) and total body water (r=0.148). Body fat percentage had a positive correlation with weight(r=0.147) and BMI(r=0.265) and total body water(r=0.265). In summary, the elderly(85+) in the Sung-Ju area had considerably smaller physiques than the average Korean elderly and showed a normal range of BMI in average. The IADL of the elderly(85+) appeared to have a positive correlation with lean body mass and total body water and a negative correlation with body fat percentage.

This essay studied the acting theories of Diderot, Delsarte, Meyerhold, and Artaud to know the historical formation of 'sign acting' and its theoretical and aesthetic appropriateness. The sign acting so far discussed shows the repetitive patterns of idea as follows. The sign acting (1) emphasizes the physical expression such as gesture and movement, (2) assumes that the physical expression functions as a sign evoking special emotion and thought, (3) thus recommends the imitation of the outer sign, (4) uses a tableau for the effective reception of outer sign, (5) aims for the spectator oriented aesthetics as it stresses the result of outer sign rather than the creative process of a role, (6) assumes that the emotional reaction or the intellectual understanding springs from the physical experience, (7) thus emphasizes the physical language rather than speech, (8) can attain the appropriateness of physical language by the recent theories of cognitive science. Besides having such commonness, the sign acting also reveals the individual differences. For instance, the intended sign for Diderot and Delsarte was the sign of emotion, for Meyerhold the stylized sign of circus and acrobatics, and for Artaud the spiritual sign. If Diderot and Meyerhold demands the cool consciousness for the correct sign acting, Artaud's sign acting tends to pursue the state of trance. And if Diderot, Delsarte, and Meyerhold think the sign acting on the level of sensory appeal, Artaud insists that the sign acting should dismantle the spectator's sense. As such the discussion of sign acting shows both recurrent ideas and new visions, forming an unity out of diversity. Perhaps the sign acting is a matter of practice before we consider it as a theory. It is not only supposed to have been existed practically since ancient theatre, but also used by actors consciously and unconsciously in expressing certain emotion and thought. We need to study the sign acting more academically, considering its long history and aesthetic potentials. In fact the sign acting has been an essential element of acting, in spite of bad reputation judging it as a banal and worn-out style. It is true that the sign acting, in the worst case, could produce a stereotypical expression. It was this aspect of sign acting that caused a fierce negative reaction of the realists who sought the natural expression based upon psychological truth. Of course the sign acting has a serious problem when it stays banal and artificial. But we need to see this issue from a different perspective. What is the natural expression of emotion? How is it free from the learned way of expression? In some respect, we use, in reality, a learned expression of emotion that could be accepted socially. For instance, when we attend a funeral, we use the outer sign of mourning gestures learned socially. If a semiotic expression pervades various aspects of our life, the acting, being the representation of life, seems not to be free from codified expression. The sign acting could be used consciously and unconsciously in all kinds of acting.
