Since July 2007, the government has banned the use of the existing non-legal measurement units, and has forced us to use the unified legal measurement. Therefore, the existing clothing size unit also has been changed into centimeter dimensions from inches. However, consumers have been familiar to used to the traditional inches unit. So they have the confusion to directly survey the size table sign for clothing or to contact the employee when purchasing clothing. By the current size table sign the customers can compare the inches unit and centimeters unit, but they are difficult to see it. Therefore, there is necessary to improve the size table sign by the way that can be easy to be found and seen by consumers is given to the clothing corners. In this research, three improved size table signs were developed. And they were evaluated by the consumers in terms of preferences and awareness of them. Eventually, the best size table sign was selected. From this result, if the large-discount mart use the best improved size table sign on behalf of the current one, the problems of existing size table sign will overcome and improve customer satisfaction.

In the Republic of Korea, Ministry of Construction & Transportation and Korea Water Resources Corporation manage the national groundwater monitoring network at the 169 stations and will organize the supplementary groundwater monitoring network at the 10,000 stations by 2011 year. The method that organizes the monitoring network was developed using the Analytic Hierarchy Process with pairwise comparison. Several estimation factors for the estimating every district were selected to reflect each district conditions. Their weighting value was decided by pairwise comparison and questions to the experts about groundwater The optimal number of groundwater monitoring well was calculated through the developed method. To verify this method, groundwater was monitored in Jeonju city by way showing the example. The study area In Jeonju city needs 7 stations for the supplementary groundwater monitoring network. The results monitored in 7 stations inferred the groundwater level around the study area by Kriging. The mean of residual between inferred groundwater level value from Kriging and actual groundwater level is rather low. Furthermore, the mean and standard deviation of residual between inferred groundwater level change and actual groundwater change is much lower. The Fact that 7 monitoring stations are sufficient for observing the groundwater condition in the study area makes it possible for suggested monitoring number to be proper.

The general situation of system composition and safety management of high-speed railway terminal is investigated and a comprehensive evaluation index system of operational security is established on the basis of railway laws and regulations and previous research results to evaluate the operational security management of the high-speed railway terminal objectively and scientifically. Index weight is determined by introducing interval eigenvalue method (IEM), which aims to reduce the dependence of judgment matrix on consistency test and improve judgment accuracy. Operational security status of a high-speed railway terminal in northwest China is analyzed using the traditional model of fuzzy comprehensive evaluation, and a general technique idea and references for the operational security evaluation of the high-speed railway terminal are provided. IEM is introduced to determine the weight of each index, overcomes shortcomings of traditional analytic hierarchy process (AHP) method, and improves the accuracy and scientificity of the comprehensive evaluation. Risk factors, such as terrorist attacks, bad weather, and building fires, are intentionally avoided in the selection of evaluation indicators due to the complexity of risk factors in the operation of high-speed railway passenger stations and limitation of the length of the paper. However, such risk factors should be considered in the follow-up studies.

The purpose of this study is to propose and introduce Accidents Prevention Remedies(APRs) and their priorities especially for Accident Causing factors(ACFs) drawn by surveying and analyzing how much foreign workers in Korea have been exposed to dangers at a construction site. At frist as a result of the analysis of the questionnaire which 59 foreign industrial trainees working at the construction sites in Seoul-Kyunggi area had responsed, 12 ACFs and 11 APRs were put out by using the SPSS programme. Then, through the Analytic Hierarchy Process(AHP) about the questionnaire from 96 safety and civil engineers who have experienced in managing foreign labor at the construction sites all over the country, the APRs given their priorities of relative importances are as follows; First, it is absolutely necessary that every working order to foreign workers should be made more definitely in accordance with a concrete process schedule. Second, the owners should increase investments in improving foreign workers' welfare in order to minimize their potential human error. Third, Korean language education programme for simple technical terms should be made and executed at least.
