China instituted arbitration law on September 1, 1995, after having legislated the law under the UNCITRAL Model Law. However, Chinese arbitration law has some problems related to the effectiveness of its arbitration agreement, unlike the UNCITRAL Model Law. Thus, parties in dispute who want to settle a dispute based on Chinese arbitration law as governing law have more to take into consideration because there could be serious problems related to the effectiveness of the arbitration agreement. Therefore, this paper attempted to analyze the classification of jurisdiction related to the authorization of effectiveness in arbitration agreement of arbitral organization and Chinese, verify the problems, and suggest the solutions. Moreover, the author tried to verify the problems in applying the law related to the authorization of effectiveness in Chinese arbitration agreements and suggest some improvements. This paper also suggests improvements and problems related to the selection of arbitral organizations among several conditions for effective arbitration agreement in Chinese arbitration law. Finally, the author suggests some cautions and countermeasures related to arbitrations agreement for domestic investors and traders dealing with the Chinese.

The objectives of the study were to analyze the current conditions of the“NONGCHON ILGAM GATCI”project (an income generating project for rural areas) and to suggest possible improvements. Among the 567 business which have been supported by the project, implemented in 1990 by the Department of Rural-Home-Improvement of the Rural Development Administration, 361 (63.7%) can be categorized as being in the self-supporting stage. Another 126 (22.2%) can be said to be in the incubation stage. Data for the case study was collected from 20 project sites. The“NONGCHON ILGAM GATCI”project has been progressing successfully when compared with other rural development projects. However, there are still some problems. Among the problems are the lack of a business mindset and management abilities in individuals, and the fact that the businesses and their products are not well hewn on the market. To remedy these problems, education toward improving business and management skills, a unified public relations system, and institutional support from the government are greatly needed.

In general fractal imge compression, each range block is approximated by a contractive transform of the matching domain block under the mean squared error criterion. In this paper, a distortion measure reflecting the properties of human visual system is defined and applied to a fractal image compression. the perceptual distortion measure is obtained by multiplying the mean square error and the noise sensitivity modeled by using the background brightness and spatial masking. In order to compare the performance of the mean squared error and perceptual distortion measure, a simulation is carried out by using the 512*512 Lena and papper gray image. Compared to the results, 6%-10% compression ratio improvements under improvements under the same image quality are achieved in the perceptual distortion measure.

In railway system, the first step of safety managements is the identification of current safety level. Among many safety indexes, risk concept is the prevailing and most effective one in many developed countries for the safety management. But many requirements such as, accident classification rule, risk levels or broadly acceptable regions, safety cost benefit analysis, VPF, equivalent fatality and failure database are needed for the application of risk concept in railway. Basic requirements for the application of risk concept on railway safety improvements are derived in this study.

In this study, experimental and theoretical methods were applied to understand brake squeal noise VVVF rolling stock on tracks. Trailer cars needed to payed a particular attention, because they were the major source of brake noise. VVVF rolling stocks for lines no 1 of the subway system in Seoul were used for experimental analyses. In order to study brake squeal noise, a dynamometer test at the S&T Brake, Co., which was a manufacturer of brake pads had performed. For measuring vibration and noise, vibration tests of brake parts (brake lining, brake lining head, back plates, etc.) at the SNUT were executed. Also, vibration tests of disc assembly and lining block at the heavy maintenance shop of the Gunja depot were performed. The modal analyses by using an ANSYS which was one of the CAE commercial program were simulated to know the relationship to the mechanism of brake noise. On the based of the tests and the simulations it was found that specific frequencies of the brake parts affected squeal noise, and improvements for reducing squeal noise were proposed.

The purpose of this paper is to analyze the 24 mail center's efficiency and productivity changes from first quarter to fourth quarter of 2008 using window analysis and Malmquist productivity index. Row views of window analysis results make it possible to determine trends and/or observed behavior with the same data set, and column views to examine the stability of results across different data sets. Malmquist productivity indexes greater than unity translate into improvements in productivity, and less than unity mean deterioration in performance over time. The results of this study suggest that DEA models under dynamic situations such as window analysis and Malmquist productivity index enable us to comprehend the efficiency and productivity changes over time and to show the direction of improvements.

In this study, improvements for error correction, speed, position, and rotation calculation algorithms have been proposed to be used in resolver to digital conversion (RDC) systems. The proposed open-loop system drives the resolver and uses the output signals of the resolver signal to estimate the real time position, the instant speed, and the rotation count with high resolution and accuracy even at high speeds and noise. The proposed solution implements strong features of both closed and open loop based systems while eliminating their weak points. The improvements proposed is resistant to noise owing to digital FIR filter and data averaging techniques. The implementation used for proof of concept is implemented on a hardware using an FPGA and configurable to be used by any resolver.

This study investigated the status and problems of the post-project environmental management for development projects and suggested improvements of the system to achieve effectiveness for the system of the sea area utilization consultation. The post-project environmental management has had several problems such as the neglect of implementations and checks for the consultation items, the lack of actions and notifications of results, the absence of awareness and expertise of the post-project environmental management. In addition, although it is very important to verify results of actual change and modelling of marine environment before and after the projects, the marine environmental monitoring and assessment have been perfunctorily carried out. Thus, for the improvements of the post-project environmental management to the system of the sea area utilization consultation, it is extremely necessary for related stakeholders to raise awareness of the post management and implement it faithfully, and establish the post management system for conflict resolution and enforce sanctions and accountability against executory items. Furthermore, it should establish systematic monitoring system of marine environmental impact survey.
