Meanwhile, the meaning has been emphasized in mathematics. But the meaning of meaning had not been clearly defined and the meaning classification had not been reported. In this respect, the meaning was classified as expressive and cognitive. Furthermore, it was reclassified as mathematical situation and real situation. Based on this classification, we investigated how student recognizes the meaning when solving mathematical modeling problem. As a result, we found that the understanding of cognitive meaning in real situation is more difficult than that of the other meaning. And we knew that understanding the meaning in solving of equation, has more difficulty than in expression of equation. Thus, to help students understanding the meaning in the whole process of mathematical modeling, we have to connect real situation with mathematical situation. And this teaching method through unit and measurement, will be an alternative method for connecting real situation and mathematical situation.

At public spaces, signs have purposes of communicating their information clearly. Especially directional signs point out the proper route showing our surroundings. The present directional signs which are indicating 3-dimensional direction in a 2-dimensional mode seem to be difficult to understand as we are moving. This study has the purpose of investigating the role of present signs and suggesting visually effective directional signs, in particular arrows. Firstly, this study surveyed the user's attitude on directional signs in case of subway station. The research shows that the present directional signs hardly perform their roles to communicate the directional information, which means the need of newly expressed arrows. In this study we consider a new effective expression on the viewpoint of human cognition mechanism. So it is thought that those trials are helpful to efficient sign system.

I think that South Korea's subway system is technologically advanced like industrialized nations compared to its short history of twenty-six years old, but it is still a little behind in terms of artistic point of view. But, as the subway system is becoming to one of the major transportation, the subway passengers can use not only transportation but also new cultural space. In term of this view, many people are getting interested in the subway murals these days, but the murals in the subway system have been produced inconsistently, so the function is not efficient. Therefore, I compared and analyzed the illustration on the Korean subway murals and successful cases of foreign countries, so I tried to indicate the problems and directions on the Korean subway murals. And I also made a try to stimulate the interest on the new cultural space and provide a pleasant atmosphere and an aesthetic sense. And I expect that near future subway murals will be produced well-planned and professional way even on line aide of administrative and real production for the consents of expression, method of expression and colors.

Vibration analysis is one of the most powerful tools available for the detection and isolation of incipient faults in mechanical systems. The methods of vibration analysis in use today and under continuous study are broad band vibration monitoring, time domain analysis, and frequency domain analysis. In recent years, great interest has been generated concerning the use of time- frequency repesentation and its application for a machinery diagnostics and condition monitoring system. The objective of the study described in this paper was to develop a new diagnostic tool for the rotating machinery. This paper introduces a new time frequency representation. Directional Winger-Ville Distribution, which analyese the time-frequency structure of the rotating machinery vibration.

This study was to investigate the choice & satisfaction factors of a musical as culture contents, and I will recognize it about relation between these two factors. To achieve this, I did a survey with spectators of . Factors analysis and simple/multi regression analysis are utilized as data analytical methods. The choice factors of musical showed that it was five factors extracted a price and facilities, production and directing, marketing, musical quality, OSMU. The satisfaction factors of musical was four factors extracted a production company and trust of advertisement, artistic presentation, harmony of All members of the cast, level of leading actor or actress. The choice of musical influenced satisfaction factors showed that it as performance prices and facilities level is reasonable, and spectators expect high satisfaction regarding a performance. Analysts say that, Pricing to be exposed to quality of a work in order to raise musical satisfaction shall be performed. Also, An exaggerated performance marketing is negative to satisfaction of an audience compare with quality of a work it was confirmed to affect. This study suggests that important point is planning, directing and marketing of a musical.

The underground buried pipelines of Natural gas are relatively safer than any other pipelines of chemical plants, because Natural gas is non-corrosive fluid. But Natural gas is supplied normally the downtown area. So, it may be a disaster because of corrosion which is caused interference facilities, environment and third party accident which is caused facilities construction. Especially, it is very difficult to find out and inspect damages of pipeline because of buried pipelines. Therefore this paper approached to select and manage risk region pipelines according to introduction of underground buried pipeline's risk concept. Risk was indicated three parts - corrosion factor, design and construction factor, maintence and management factor - in this paper, Therefore qualitive risk of pipelines showed score as quantitative number. Also it was thought to be helpful in confidence and safety management that the concept of key index and failure supplementation measures to cost introduces this program. We developed this risk assessment program using visual basic tool and interfaced GIS.

The purpose of this study was to analyze the cliche for English-Korean interpretation and translation with special reference to the cliche based on the Holy Bible texts. Cliches are figurative or literal expressions and are overused expressions in various different cultures. In addition, cliches are languages, a tool of communication in an appealing way. Therefore, cliches are must be clearly distinguished from the term of idioms that are figurative phrases with an implied meaning; the phrase is not to be taken literally. Also, cliches are the single most important factor that characterizes socioculturally. Through this empirical analysis on cliches we see that this study has conceptualized the meaning of cliche. Based on this result, I expect that anyone who researches English-Korean interpretation and translation field should be concerned about cliches. I hope this study will be a guide to the right uses of cliches in English language fields.

The objective of this study was to estimate genetic trend on racing time of Thoroughbred racehorses in Korea, using a total of 209,725 racing records of 9,934 racehorses collection from January, 1990 to December, 2006. Phenotypic trends for all distances were negative at a rate of －0.148, －0.137, －0.137 and －0.139 second per race year for distances of 1,000m, 1,400m less than, 1,700m more than and overall dataset, respectively. Environmental trends were similar to phenotypic ones in all distances and trends in permanent environmental and jockey effects by race year were not found. Average genetic improvements for racing time were －0.037 and －0.030 second per race year at the 1,000m and overall dataset, respectively, which is low. But Genetic trends were decreased consistently. There is need to establish the genetic improvement program for quality of racehorses.

The words a speaker uses can be regarded as the core, the main issue and a symbolic icon of what he says. Applying this to presidents' addresses of each English literary society in Korea shows that frequency in use and the linkage of words they use in their addresses are value and ideas executive officers pursue. The purpose of this study is to analyze the contents of presidents' addresses introduced in home page of each English literary society in Korea and investigate features and constitution of them each, focusing on analysis of a language network. The results of this study show the features of resemblances and differences of commonly-used words. In addition, these results appear to suggest that they can be also applied to a comparative study between the English literary societies in Korea.
