Determining the meaning of a keyword in a speech dialogue system is an important technology for the future implementation of an intelligent speech dialogue interface. After extracting keywords to grasp intention from user's utterance, the intention of utterance is determined by using the semantic mark of keyword. One keyword can have several semantic marks, and we regard the task of attaching the correct semantic mark to the user's intentions on these keyword as a problem of word sense disambiguation. In this study, about 23% of all keywords in the corpus is manually tagged to build a semantic mark dictionary, a synonym dictionary, and a context vector dictionary, and then the remaining 77% of all keywords is automatically tagged. The semantic mark of a keyword is determined by calculating the context vector similarity from the context vector dictionary. For an unregistered keyword, the semantic mark of the most similar keyword is attached using a synonym dictionary. We compare the performance of the system with manually constructed training set and semi-automatically expanded training set by selecting 3 high-frequency keywords and 3 low-frequency keywords in the corpus. In experiments, we obtained accuracy of 54.4% with manually constructed training set and 50.0% with semi-automatically expanded training set.

Generally, the Internet Address Resources Act is intended to protect the public from acts of Internet "cybersquatting", a term used to describe the bad faith, abusive registration of Internet domain names. In determining whether a person has a bad faith intent, a court may consider factors such as, (1) the trademark or other intellectual property rights of the person, if any, in the domain name, (2) the extent to which the domain name consists of the legal name of the person or a name that is otherwise commonly used to identify that person, (3) the person's prior use, if any, of the domain name in connection with the bona fide offering of any goods or services, (4) the person's bona fide noncommercial or fair use of the mark in a site accessible under the domain name, (5) the person's intent to divert consumers from the mark owner's online location to a site accessible under the domain name that could harm the goodwill represented by the mark, either for commercial gain or with the intent to tarnish or disparage the mark, by creating a likelihood of confusion as to the source, sponsorship, affiliation, or endorsement of the site, (6) the person's offer to transfer, sell, or otherwise assign the domain name to the mark owner or any third party for financial gain without having used, or having an intent to use, the domain name in the bona fide offering of any goods or services, or the person's prior conduct indicating a pattern of such conduct.

In this paper, a large-scale study on users' understanding of search-based advertising is presented. It is based on (1) a survey, (2) a task-based user study, and (3) an online experiment. Data were collected from 1,000 users representative of the German online population. Findings show that users generally lack an understanding of Google's business model and the workings of search-based advertising. 42% of users self-report that they either do not know that it is possible to pay Google for preferred listings for one's company on the SERPs or do not know how to distinguish between organic results and ads. In the task-based user study, we found that only 1.3 percent of participants were able to mark all areas correctly. 9.6 percent had all their identifications correct but did not mark all results they were required to mark. For none of the screenshots given were more than 35% of users able to mark all areas correctly. In the experiment, we found that users who are not able to distinguish between the two results types choose ads around twice as often as users who can recognize the ads. The implications are that models of search engine advertising and of information seeking need to be amended, and that there is a severe need for regulating search-based advertising.

A PC-based system for measuring and analysing random neutron process in the thermal reactor is developed and applied to TRIGA Mark-II reactor at KAERI. It is confirmed that this system has several advantages compared to conventional methods. So far, two techniques, autocorrelation and variance to mean ratio (VTMR), have been applied for analysing the count data collected from the single detector by using this system. The results of the two techniques agree within acceptable difference, but VTMR's results show much superior statistical reliability than those of autocorrelation especially when it is near critical. The $\beta$/Λ of TRIGA Mark-II reactor is measured to be about 125/sec when the reactivity is within -3＄ and about 150/sec when it is below -4＄.

The purpose of this study was to perform the fetal education effectively for the delivered woman and her husband. This study was conducted by the questionnaire survey on 199 delivered women and their 171 husbands at several hospitals located in Seoul and Kyonggi Province from February 28 to March 26, 2002. The contents of questionnaire included the purposes, the cognition and the practice of fetal education. The SAS program was used for the statistical analysis of the data. The character of subject was analyzed by the percentage. The difference between the cognition and practice of fetal education was analyzed by t-test, ANOVA, Wilcoxon rank sum test. The factor analysis affected on the practice of fetal education was adopted by Multiple regression. The results were as follows; 1. In the purpose of fetal education, the well- balanced emotion showed the highest mark. The cognition of fetal education(woman:$4.39{\pm}0.52$, husband:$3.88{\pm}0.70$) and the practice (woman:$3.88{\pm}0.60$, husband:$3.83{\pm}0.70$) showed the relatively high mark, but the score of cognition showed higher than that of practice. 2. In the comparison of the cognition between the delivered woman and the husband for the fetal education the item of the mental or health state would affect unborn baby, which occupied the highest mark in both woman and the husband(woman:$4.81{\pm}0.44$, husband:$4.81{\pm}0.50$). But they were prohibited to eat the deformed food, which showed the lowest mark(woman:$3.19{\pm}1.12$, husband:$3.21{\pm}1.29$). 3. In the comparison of the practice for the fetal education between the delivered woman and the husband, the practice for the healthy baby showed the highest mark in woman ($4.51{\pm}0.71$), which had a statistically significant difference(P=0.025), compared with that of the husband($4.13{\pm}0.99$). 4. In the comparison of cognition and practice for the fetal education, the general character was associated with the duration of marriage, the satisfaction with marriage and the support of husband on pregnancy. The mark was associated with the age of woman, the level of education and the first birth. 5. The significant factors influencing on the practice for the fetal education were connected with the cognition of fetal education, age, satisfaction with marriage, the support of husband on pregnancy, the type of family, the experience of delivery and the state of health during the period of pregnancy. etc. In conclusion, it is indicated to make effort for transforming and developing the traditional fetal education in accordance with the modern fetal education. And it is suggested that the fetal education might be recognized by all members of family, and the importance of husband's role for the fetal education should be informed as well as that of woman's.

Mark-Recapture method for open population commonly use Jolly-Seber method. This method assumes that all animals are equally likely to be caught in each sample (the equal catchability). This objects are making introduction of Mark-Recapture method for open population and using the robust design that combine a open population method with close population method to solve upper problems. Then population growth rate estimators that are derived Pollock's Jolly-Seber parameters and Kendall's Jolly-Seber parameters are estimated.

A lane departure warning system based on single lane mark detection is presented in this paper. The proposed system is focused on the robust detection of lane departure, even when one of the left or the right lane mark cannot be detected because of poor illumination or abrasion. Experimental results show that the proposed system warns lane departure, even if only a single lane is detected.

An aircraft made an emergency landing through the loss of capability controlling steering. A torsion link which is a part of steering apparatus has been adrift from the steering system and the bolt connected to the steering link has fractured. At the same time, the FLIR(Forward Looking Infrared Radar) mounted in front of the steering link has been also damaged. In the early of this investigation, we considered the failure of the FLIR had occurred first, that FLIR hit the steering link and finally the bolt fractured. The fractured section of the bolt has shown a beach mark and a dimple mark as well. The outside of the bolt has shown a large deformation by a heavy load. As a result, we have found out what the cause of the heavy load and the fractures for bolt, link and FLIR have occurred in what order.
