Traditional slicing techniques make slices through dependence graphs. They also improve the accuracy of slices. However, traditional slicing techniques require many vertices and edges in order to express a data communication link because they are based on static slicing techniques. Therefore the graph becomes very complicated, and size of the slices is larger. We propose the representation of a dynamic object-oriented program dependence graph so as to process the slicing of object-oriented programs that is composed of related programs in order to process certain jobs. We also propose an efficient slicing algorithm using the relations of relative tables in order to compute dynamic slices of object-oriented programs. Consequently, the efficiency of the proposed efficient dynamic object-oriented program dependence graph technique is also compared with the dependence graph techniques discussed previously As a result, this is certifying that an efficient dynamic object-oriented program dependence graph is more efficient in comparison with the traditional object-oriented dependence graphs and dynamic object-oriented program dependence graph.

We propose the representation of a improved dynamic object-oriented program dependence graph so as to process the slicing of object-oriented programs that is composed of related programs in order to process certain jobs. We also propose an efficient slicing algorithm using the relations of relative tables in order to compute dynamic slices of object-oriented programs. We programmed the algorithm by using fortran and Visual C++. The procedure that computes the dynamic object-oriented program slices using the improved dynamic object-oriented program dependence graph(IDOPDC) is divided into four steps. Consequently, the efficiency of the proposed improved dynamic object-oriented program dependence graph(IDOPDG) technique is also compared with the dependence graph techniques discussed previously. As a result, this certifies that an improved dynamic object-oriented program dependence graph is more efficient in comparison with the traditional dynamic object-oriented program dependence graph(DOPDG).

Software engineers generally analyze the program behavior under the test case that revealed the error, not under any teneric est case. In this paper we discuss the dynamic slice consisting of all statements that actually affect the value of a variable occurrence for a given program input. We propose an efficient algorithm to make dynamic program slices. The eficiency of this algorithm is evaluated on some developed program. results are shown by a marking table of execution history. Dynamic Dependence Graph, and Reduced Dynamic Dependence Graph, Consequently, the efficiency of the proosed algorithm is also presented by the compariso with algorithm that was announced previously.

Objectives : The purpose of this study is to analyze and to compare the difference and the change between dynamic balance exercise group and dynamic balance exercise with core program exercise group. Also, based on this data, to prescribe effective exercises for hemiplegic patients and the pubis in order to achieve more effective dynamic balance exercise rehabilitation and better dynamic balance exercise in the field of therapeutical exercise. Methods : Twenty subjects(Core program exercise plus Dynamic balance exercise group, CP: 10, Dynamic balance exercise group, NCP: 10) were chosen among hemiplegic patients. Measurements of dynamic balance were evaluated at initial presentation(pretest) and after 4, 8, 12 weeks'. Paired t-test and Repeated measured ANOVA was utilized to detect the mean difference between the groups. Results : Firstly, after 4 weeks' and 8 weeks' and 12 weeks' CP exercise and NCP exercise, there were all significant difference to increase dynamic balance (p<0.05). secondly, after 4 weeks' and 8 weeks' and 12 weeks' CP and NCP exercise, there was significant difference to increase dynamic balance more CP group than NCP group. Lastly, among 4 weeks' and 8 weeks' and 12 weeks' CP exercise, there was progressively significant difference to increase dynamic balance(p<0.05). Conclusions : This study showed that dynamic balance exercise with core program exercise is an effective treatment strategy for hemiplegic patients than dynamic balance exercise rehabilitation.

A dynamic simulation program for pantograph-catenary system is developed based on a mode superposition method to predict current collection performance. Formulations for the dynamic simulation are presented in this paper. The number of modes which should be considered for a KTX catenary system is reviewed through frequency response analyses. The responses for GPU pantograph - KTX catenary system are simulated with various train speeds. The our simulation results are in reasonably good agreements with RTRI simulation program, SNCF simulation program, and BR simulation program.

Purpose: The purpose of this study is to provide an efficient and scientific basis for muscle activity (%MVIC) of RA, EO, VL, HS muscles and balance in soccer players through dynamic lumbar stability exercise and static lumbar stability exercise. Methods: This study included 23 soccer players belonging to D University of J province who attended the program for 30 minutes at a time and three times a week for 4 weeks. Of these 13 attended the dynamic lumbar stability exercise (DLSE) program and 10 the static lumbar stability exercise (SLSE) program. The differences between the effects of the dynamic lumbar stability exercise program and static lumbar stability exercise program were analyzed. Results: To increase muscle activity (%MVIC) and balance (WPL), the dynamic lumbar stability exercise program was more effective than was the static lumbar stability exercise program. 1) The %MVIC of trunk muscle (RA &EO) and lower extremitys muscle (VL & HS) increased from before training to after training in the case of the participants who performed the dynamic lumbar stability exercise. 2) The whole path length (WPL) decreased from before the training to after the training. The 2 groups significantly differed in this regard. Conclusion: Dynamic lumbar stability exercise program helps to improve the balancing ability and muscle activity in a soccer players who requires both muscle activity and balance than does any other players.

For the operation of the practical software systems, the development of new software, extension and modification phases of current software are successively needed through the new requirements added and their errors debugging detected. We need to understand current program exactly during a working serial jobs. When we'd like to extract the statements which influence the variable of specific statement of program, we generally analyze the program behavior through execution trace of program for the input values. It is important to compute dynamic program slice related to all statements that actually affect the value of a variable occurrence for a given program input and to develop techniques of its implementation. But traditional dynamic slicing techniques are inconvenient to make program execution history at the beginning implementation. In this paper, we propose a new improved algorithm which can produce program slice by use of dynamic control information and program slicing techniques except execution history file. Also we can find that the proposed program slicing approach is more efficient than the traditional program slicing algorithm on the practical testing environment.
