As International considerations about the Barrier-Free environment increase, Korean Barrier-Free Environment Certification System has operated since 2008 in Korea. The purpose of this study is to find way to improve evaluation items, so this study analyzed the result of examination certified facilities and investigated the importance of the evaluation item for conducted a questionair survey with the BF experts. As a result, a lower scored and high important item should assign a higher score or lower the difficulty level, so induces applicants to be certified. Second, a higher scored and lower important item should assign a lower score or increase the difficulty of evaluating. The results suggested are expected the use in the improvement direction of BF certification evaluation items.

Two ways of improvement of the strut for the HCF was made in this paper. The strut for the existing HCF is a passive link, which results the posture of the HCF and related bones. The accuracy of the HCF depends on the accuracy of the strut length. A "digital gage" was proposed to increase the accuracy of the strut by presenting the measuring result as figures in manual mode operation. And a "motorized strut system" was designed for the automated HCF operation. A strut was equipped with a motor, "motorized strut" can be operated manually and automatically. In automatic mode, the HCF operating data is generated by the HCF schedule package in PC and is downloaded to the "motorized strut system" controller. By these two improvements, changes in orthopedic equipments like HCF and other Ilizarov fixators are expected.

In centrifugal barrel finishing, it is easy to establish the optimum working conditions for different workpieces. As they are adjusted in trial and error practically, production efficiency and quality are some- times low In the present paper, firstly, installation of the barrel finishing machine, finishing purpose and working conditions have been analyzed in order to eliminate the defects of the finished surface. Secondly, on the basis of this result, quantity of the water and selection of the media and the compound, etc. have been investigated. As a result, production efficiency and quality have been improved under the specified optimum working conditions. In addition, durability of the media and the compound has been tested experimentally. As a result, it was found that the expected life of the media is about 85 hrs and that of the compound is about 5 hrs. Besides high quality control has been achieved by newly proposed inspection at regular intervals.

Properties of newly developed paper from Red Algae Pulp (RAP) were examined. The paper samples were prepared according tomixing RAP fiber with wood fibers, HwBKP and SwBKP, to form a paper with 60 g/$m^{2}$ in weight. It was prepared in three to four different levels of refining degree and pressure so that it can reveal different bulk level in order to clearly compare the opacity at equivalent bulk for each furnish compositions. printability of RAP fiber revealed superior effect on print through repression and initial ink absorption. Those properties are expected to improve further if printability improvement effect due to smoothness improvement is added.

In today's R&D environment, as the complexity of IT systems increases and the expected quality level for R&D outcomes enlarges, it has been critical issues for us to effectively define and improve the R&D standard processes tailored for our organization and projects. To meet this needs, we defined the R&D standard processes based on the international standards for systems and software engineering and our existing traditional work methods, and then applied them of our ongoing projects. Now, we are improving our defined R&D standard processes continuously by monitoring of the processes and products and through the feedback of the application results. In this paper, we introduce the R&D standard process model developed by our organization (E research Institute in Korea) and the requirements and approaches used for their development and improvement. We compare our defined R&D standard processes with ISO/IEC 15288 which is the international standards for systems engineering and summarize the lessons learned through their development and improvement.

This paper is presenting the performance evaluation on the installed concrete panels. As a result of the evaluation, the resistance to track displacement of temporary support structure was improved and it resulted in the improvement of work stability during installation. And, by the application of new technology and the saving of concrete consumption, both workability and cost were improved and, therefore, the shorter project period and cost saving can be expected. Furthermore, as a result of noise & vibration measurement at site, it has shown good effects of anti-noise and anti-vibration. In conclusion, this process was proved as very effective for track improvement.

For continuous improvement of the railway customer satisfaction service, more objective evaluation and development system for software and hardware shall be built. The entire activity of railway customer is the interface between the customer and software/hardware services. Customer's activity was investigated by participating observation and objective observation, and considering the connection of all the activities, it was divided into 9 categories and 43 items. Although the detailed activity of customer would vary per item, they show more than 430 different activities under general condition. Also, the customer's activity varies according to the numerous variants such as physical, mental, environmental and cultural features. Especially, as lots of changes, diversification and high-quality of railway industry are expected according to the middle and long term plan on railway industry development, it is necessary for experts in various fields to perform cooperative research aggressively to improve the customer satisfaction service continuously based on continuous customer activity research.

Accuracy improvement of a self-mixing semiconductor laser range finder is predicted by simulation, in which the laser modulation current is reshaped to give an ideal triangular waveform of the optical frequency change. The maximum range measurement error of less than 0.1% in a wide range of O.1m to 1m is expected by the reshaping of the modulation current. Experimental verification of the effect of current reshaping on the linearization of the derivative of the optical frequency change curve is given.
