Since 2010, issues for data sharing and data exchanging in hospital information systems have been emerged. In order to solve the issues, standards should be applied to develop the systems and there should be no ambiguities between terminologies in the systems. In this paper, the terminology mapping system for narrative clinical records was implemented. The term mapping precision was 83.4%. This system could help to upgrade the text based clinical system and it would be expected to support for high quality clinical services.

The job design was frequently tried in many enterprises in order to give workers the job satisfaction, but there remains obscure about what kinds of human factors in job yield the satisfaction. This study is concerned with an experimental method for job design to account for such findings that work with conveyor gave workers unsatisfaction, and that enlarged job of work resulted in high job satisfaction.

It is expected to confront numerous technological advancements in ter railroad technology with an opening of state-of-art Kyung-Bu High Speed Railroad that permits traveling speed in excess of 300 Km/hr. Expansions of railroad facility such as revival of silk railroad in Eurasia due to the connection of South-North Korea and modernization of rolling stock and ancillary equipment have certainly contributed to the technological development of Korean Railroad. Such technological advancements will provide of opportunities to participate in foreign projects that have been offered in past years. Thus, a comprehensive plan and R＆D policy is necessary to continuously raise and upgrade national competitiveness in the railroad industry.

Due to the rapid development of telecommunication industry, most telecom operators are investing to upgrade their access networks by using optical cables instead of copper cables. Building new telecom ducts for optical cable installation requires so huge capital expenses that most telecom operators need to remove unused copper cables in order to secure enough space to in-stall optical cables. In this paper, we will present a alternative method to extract copper from removed copper cables.

We, previously, proved that the noise in the vertical readback from some of beam position monitors (BPMs) in the vacuum chamber of Pohang Light Source (PLS) are caused by the transverse electric (TE) longitudinal harmonic resonances. Based on this analysis, we now design the shunt structure to remove the TE mode resonces near the BPMs operation frequency of 500 MHz in the storage ring vacuum chamber of PLS upgrade project (PLS-II). The simulation result and experimental test result will be presented.
