The objective of this study is to identify the current state of usage and needs for Smart Technology (ST) in the elderly care facilities based on the point of view of staff members. Using survey via mails, data were analyzed with responses from top- or middle-level staff members working in 171 elderly care facilities located in Seoul, Gyeonggi-do, and Chungcheongnam-do. Results indicated that the most needed smart technology was home automation, followed by nurse call system and health monitoring. The technology with the highest feasibility was health monitoring, followed by nurse call system and video phone. Staff members in higher positions working in the elderly care facilities had the highest expectation in improving the image of their facilities by using ST, while they had low expectation for the fact that ST may increase the locus of control of the elderly. This study implies that ST implementations may vary depending on the level of responsibility of staff members and ST how people responsible for the elderly care facilities subjectively perceive the ST.

The Reliability started for MILitary purposes during World War II in 1942, getting more important for maintenance, safety, etc in modern society. As technologies develop, also international standards for measuring the reliability is advancing. RAMS activities for maintenance, safety verification is material to national railroad. And for this, it needs quick response for the changes of standards. Even now standards are upgrading for developing electronic technologies. Therefore analysis of failure rate's trend about such standards is judged necessary. So We submit a this paper for comparative analysis of changing process standards according to development of electronic technologies and reliability. At first, we compared actual usage ratio of standards for understanding the current state of usage. Based of these state of usage, discuss the major standard. And then, introduced reliability standards's trend, calculation method of failure rate and difference of failure rate calculation standard according to march of time. In this paper, used standards are MIL-HDBK-217F, Telcodia, etc.

In this paper, a new field weakening algorithm which maximizes the output torque not only in steady state b but also in transient state is proposed. Considering both voltage and current limit of system, analytic solutions f for optimal torque utilization in field weakening region I and region II are obtained. This algorithm finds optimal currents considering dynamic vol떠ge limit based on flux and speed. So the maximum usage of stator v voltage even in transient state results in the maximum torque and fast response time. Simulation and e experimental results show the effectiveness of the proposed field weakening scheme.
