Purpose : This study examined the effects of an integrated management program on physical function, cognitive function, and depression in patients with subacute stroke. Methods : A nonequivalent control group design was adopted. The participants were assigned to either the experimental group (n=20) or control group (n=23). The experimental group received an 8-week integrated management program and standard rehabilitation service (i.e., physical therapy and occupational therapy), while the control group received the standard rehabilitation service only. Physical function was measured as gait speed and balance ability using the Berg Balance Scale (BBS). Cognitive function was measured with neuro-behavioral cognitive status examination (NCSE), and depression was measured using the Beck Depression Inventory-II (BDI-II). Repeated measure ANOVA was used to determine changes in physical function, cognitive function, and depression over 8-weeks. Results : The interaction between group and time was significant, indicating that the experimental group showed improvement in gait speed, balance ability, cognitive function (linguistic ability, linguistic memory, reasoning), and a decrease in depression compared to the control group. Conclusion : These results indicate that the integrated management program developed herein was beneficial in restoring physical function, cognitive function, and depression in subacute stroke patients.

The purpose of this study is to investigate the influence of the mentoring function and mentor trust on the intention to reparticipate in the mentoring program, focusing on university students in fashion related departments. To achieve the purpose, research was conducted through a survey questionnaire. The questionnaire data from 223 university students in fashion related departments who experienced mentoring programs were analyzed. SPSS 18.0 and AMOS 7.0 statistical packages were used to investigate a structural model and test research hypotheses. The results derived from the analysis of the questionnaire survey were summarized as follows. First, the result showed that the mentoring function was composed of three factors: a sensitivity developmental function, psychosocial function, and fashion career developmental function. Second, the sensitivity developmental function, psychosocial function, and fashion career developmental function positively affected mentor trust. Third, the sensitivity developmental function positively affected the intention to reparticipate in the mentoring program, while the psychosocial function and fashion career developmental function did not influence the intention to reparticipate in the mentoring program. Fourth, mentor trust positively influenced the intention to reparticipate in the mentoring program. The results of the current study would be useful for the professor and university administrator who would like to establish a mentoring program in a fashion related department, by exploring the relation of mentoring function, mentor trust and the intention to reparticipate in the mentoring program.

In this paper we consider detection of a discontinuity point in the variance function. When the mean function is discontinuous at a point, the variance function is usually discontinuous at the point. In this case, we had better estimate the location of the discontinuity point with the mean function rather than the variance function. On the other hand, the variance function only has a discontinuity point. The target function in order to estimate the location can be used the second moment function since the variance function and the second moment function have the same location and jump size of the discontinuity point. We propose a nonparametric detection method of the discontinuity point with the second moment function. We give the asymptotic results of these estimators. Computer simulation demonstrates the improved performance of the method over the existing ones.

To reduce tsunami hazards, it is necessary to develope the methods which can simulate tsunami wave signals of coastal areas. In the present paper, it is attempted t use Sign Method for analyzing and simulating recorded tsunami signals. A tsunami record Y(t) can be represented as the convolution integral of a source evolution function E(t') and a wave propagation function K(t-t') Y(t)=.int. E(t')K(t-t')dt' A source function contains the peculiarities of a tsunami generator. A wave function is a kind of transfer function which contains the characteristics of a wave propagation path. The source functions and the wave function and the wave functions of 9 Korean coast points and 6 Japan coast points are estimated, and the tsunami wave signals are simulated by the convolution integrals of the source functions and the wave functions. According to the results of analysis, the Sign Method is an effective method for simulating tsunami wave signals of Korean coast points which are located far from tsunami source areas. Furthermore, if the source function of a neighboring point ad the wave function of an another tsunami are given, unrecorded tsunami wave also can be estimated.

The method of function synthesis is essential when we control the systems not known their characteristic, by predicting the function to satisfy a relation between input and output from the given pairs of input-output data. In general the most systems operate non-linearly, it is easy to come about problem is composed with combinations of parameter, constant, condition, and so on. Genetic programming is proposed by one of function synthesis methods. This is a search method of function tree to satisfy a relation between input and output, with appling genetic operation to function tree to convert function into tree structure. In this paper, we indicate problems of a function synthesis method by an existing genetic programming propose four type of new improved method. In other words, there are control of function tree growth, selection of local search method for early convergence, effective elimination of redundancy in function tree, and utilization of problem characteristic of object, for preventing function from complicating when the function tree is searched. In case of this improved method, we confirmed to obtain superior structure to function synthesis method by an existing genetic programming in a short period of time by means of computer simulation for the two-spirals problem.

Goal of this study is to perform the correlation about Gross motor function, eating-drinking function, and oral motor function, to identify necessity for invervention of feeding disorders on severity of the function of children with cerebral palsy. Subjects were 61 children diagnosed with cerebral palsy. The subject were evaluated for oral motor function, feeding function by GMFCS, EDACS, OMAS. The results of this study showed a significant correlation between gross motor function, eating and drinking functions, and oral motor functions. That is, the more severe the deterioration of the motor function, the lower the functional level of eating and drinking and oral motor function deterioration. In evaluating and treating the eating activity of children with cerebral palsy through this study, it seems necessary to check the eating and drinking function and oral motor function according to the gross motor function.

For a scalar rational function, the spectral data consisting of zeros and poles with their respective multiplicities uniquely determines the function up to a nonzero multiplicative factor. But due to the richness of the spectral structure of a rational matrix function, reconstruction of a rational matrix function from a given spectral data is not that simple.
