In the present paper, it removed the low frequency noise under 1Hz which get up base wandering from the various noise which is included in ECG signals. It used wavelet filter, FIR filter and Adaptive FIR filter and compared the efficiency of the filter. The set condition of 3 kind filters which are the comparative object is the next contents. Used wavelet case, used generating functions db7 and after decomposition, the low frequency of 8 phases (cA8) replaced at 0. FIR filter case, filter coefficient set 1400, cutoff frequency (${\omega}$) set 0.002. Adaptive FIR filter case, collecting coefficients (${\mu}$) with 0.005. The comparative result from the output wave shape and FT spectrum, wavelet is excellent in base wandering removals compared FIR filter and Adaptive FIR filter. And SNR comparisons, wavelet filter(44.16) is high compare with other two filters(25.19 and 15.94).

We study the dynamics of transcendental entire functions with Siegel disks whose singular values are just two points. One of the two singular values is not only a superattracting fixed point with multiplicity more than two but also an asymptotic value. Another one is a critical value with free dynamics under iterations. We prove that if the multiplicity of the superattracting fixed point is large enough, then the restriction of the transcendental entire function near the Siegel point is a quadratic-like map. Therefore the Siegel disk and its boundary correspond to those of some quadratic polynomial at the level of quasiconformality. As its applications, the logarithmic lift of the above transcendental entire function has a wandering domain whose shape looks like a Siegel disk of a quadratic polynomial.

The purpose of this study is to understand the importance of exterior environments and to identify the design guidelines for the therapeutic garden for cognitively impaired seniors with Alzheimer's disease and related dementias. The data was collected from 4 Adult Day Care Centers, 2 Nursing Homes, & 1 Assisted living in the U.S.A. from 2001 to 2002 by interview and the floor plan about the outdoor space. Although some may believe that patients with Alzheimer's disease and related disorders are unresponsive to environment, evidence shows that environments especially designed for cognitively impaired seniors can maintain or increase their level of functioning. The use of specially designed exterior environments nay have in reducing incidents of aggressive behavior, and contributing significantly to a wanderer management program. The checklist includes 6 dimensions： safety environment, various sensual stimulations, social interactions, wandering, privacy, and support orientation and reality. The results indicated that the exterior environment have to support wandering behavior, orientation and reality.

This paper propose a two pole phase compensated titer to remove baseline wandering and preserve ST-segment accuracy in real time environment. Bilinear transformed null phase filter(ideal filter), Standard FIR filter and Cubic spline filter are evalauated in the same condition. The proposed phase compensated filter shows better performance than standard filter in real ECG test and triangular pulse test.

The purpose of this study is to build fundamental data related to corridor space for nursing home design. Elderly with dementia were observed in corridor space at two nursing homes in In-cheon City. Two types of behavior were found out through in-depth observation; Group and Personal behaviors. Group behaviors were varying according to the type of programs such as rest, care, diet, and therapeutic services. Personal behaviors could be classified into wandering and private seclusion. These two behaviors were influenced by management programs of facilities, services of care-givers and individual characteristics of residents. The result of this study was discussed on the following matters: 1) Optimum size of residential unit; 2) Working spaces of care-givers; 3) Relationship between bedroom and common space for gathering; 4) Planning for wandering path; 5) Familiarity of interior finishing materials

Focusing on the hermeneutic instability of a key word of Paradise Lost, "wander," this study attempts to situate John Milton's early modern epic in the longue $dur{\acute{e}}e$ historical transition from seignorial to capitalist mode of production, especially the displacement and reorganization of producer population, a corollary of early phase of modernization. The historic experience of vagrancy and its normalization, and the concomitant shift of the primary human sociability from given to voluntary bonds, I suggest, shape and inform Milton's early modern rewriting of the Biblical story of the fall and his revising of the heroic epic romance into a plebeian romance of a wandering, companionate couple. While building on the critical consensus on this poem's deliberate distancing from the tradition of classical epic and chivalric romance, this essay argues that Milton re-appropriates and re-channels the aspirational aspect of chivalric wandering, or mobility, for his plebeian heroes, a companionate conjugal couple. The hermeneutic instability of the word wander, this essay suggests, captures the duality of the historic experience of vagrancy, both the tragic experience of displacement and the liberational and uplifting dimension of that experience.

In this paper, we study the condition that a given homeomorphism has a square root and give an example of a wandering homeomorphism without square roots.

This study aims to evaluate the effects of aromatherapy and a foot reflex massage program on the cognition, anxiety, aggressive behavior, and wandering behavior of elderly with dementia. The research design was a non-equivalent control group, quasi-experimental study where 43 subjects were divided into two groups. Aromatherapy and foot reflex massage was administered to the experimental group (N=21), and no treatment was administered to the control group (N=22). The data was analyzed using the ${\chi}^2$-test, t-test, while the repeated measures of ANOVA were utilized with the SPSS/Win 18.0 program. The experimental group did not show significant differences in cognitive function; however, it showed significant differences in anxiety, aggressive behavior, and wandering behavior in relation to the control group. Thus this research suggests aromatherapy and a foot reflex massage program as nursing intervention to improve the quality of life of elderly with dementia.

The purpose of this study was to investigate preschoolers' entry behaviors into a play group and the responses of the play group in relation to the structural characteristics of the group in a natural situation. The entry behaviors of 43 preschoolers and the responses of the play group were time-sampled. In addition the structural characteristics, including size and sex composition of the play group, and existence of a friend in the group, were checked. The following results were obtained. (1) The subjects used frequently participating behavior and wandering behavior among their entry behaviors. The wandering behavior increased and the participating behavior decreased as the size of the play group increased. Also, the subjects used wandering behaviors in the mixed group more than in the same-sex group or opposite-sex group. There was no difference in the entry behaviors according to the existence of a friend in the group. (2) The play group ignored 56% of the entry behaviors, and accepted 38% of them. The positive response of the group increased with decreasing size of the play group, whereas the entry bids were increasingly ignored as the size of the group increased. The mixed group ignored the entry bids more than the same-sex or opposite-sex group did. Also, in the presence of a friend in the group, the play group responded more positively than the group with no friend did.
