Purpose : This study aimed to understand the influence of the virtual reality program combined with cognitive activity on elderly people's balance ability. Method : We randomly divided 14 elderly people receiving daytime protection service from D daytime protection center for senior citizens located in Busan-si into a group(seven) with cognitive activity combined with virtual reality program, and the other group(seven) with only virtual reality program. In order to compare the balance ability before/after the therapeutic intervention, the Berg Balance Scale was carried out. The Mini-Mental State Examination-Korea(MMSE-K) was also conducted to compare their cognitive functions. Result : Both groups showed statistically significant differences in balance ability before/after the therapeutic intervention(p<.05) while there were no statistically significant differences in balance ability after the therapeutic intervention(p>.05). The cognitive functions before/after the therapeutic intervention were not statistically significantly different in both groups(p>.05). Conclusion : The findings showed that the application of virtual reality program combined with cognitive activity could improve elderly people's balance ability. It is considered that the application of virtual reality program can have positive influence on the improvement of elderly people's balance ability, as an intervention method for improving balance ability in the future.

Writers enroll their outcome to Program Deliberation & Mediation Committee and get the copyright preserved for the protection of IPR. The program registration is conducted through off-line and on-line methods, and especially on-line registration provides program registrants convenience along with the safety of property from external copyright invaders. However, it is a shortcoming that the integrity and confidentiality of the enrolled program cannot be guaranteed in case of internal factors such as system errors, administrator's illegal access and revision. This paper proposes the reliable system, ensuring programs and offering convenience of Digital signature management from the system errors and intruding factors by internal administrator, using the security of confidentiality, integrity and Multi-Signature Scheme for program.

The rockfall protection fences are installed to reduce rockfall damage in roads side slopes. The energy absorbing capacity of widely used rockfall protection fences is about 50kJ, But in many cases, rockfall protection fences are easily damaged even by a low level of rockfall energy. The objective of this paper is to verify the energy absorbing capacity of rockfall protection fences and investigate the behavior of them by rockfall. The LS-DYNA3D, a finite elements analysis program for dynamic movement of three dimensional objects, is used to perform the numerical simulations. In the result it is shown that rockfall protection fences absorb half of standard absorbing energy or less than it. It is inadquate for the rockfall protection fences to perform the principal function. To improve the performance of the fences, new rockfall proctection fence is proposed and numerical simulation is performed.
