지능형 음성 대화 인터페이스 구현에 있어 핵심어의 의미표지는 사용자 의도 파악을 위한 중요한 요소이다. 대화시스템은 사용자 발화의 의도를 파악하기 위해 핵심어와 그 의미표지를 이용하여 발화의 의도를 결정한다. 하나의 핵심어는 여러 개의 의미표지를 가질 수 있는 중의성을 지닌다. 이러한 중의성을 지닌 핵심어를 사용자의 의도와 일치하는 의미표지로 결정하는 것은 단어 의미 분별 문제와 유사하다. 우리는 전사된 대화 말뭉치의 약 23%를 수동으로 의미를 부착하여 핵심어에 대한 의미표지 사전, 유의어 사전, 문맥벡터 사전을 먼저 구축한 후, 나머지 77% 대화 말뭉치에 존재하는 핵심어의 의미를 자동으로 부착한다. 중의성을 가진 핵심어는 문맥벡터 사전으로부터 문맥 벡터 유사도를 계산하여 의미를 결정한다. 핵심어가 미등록어인 경우에는 유의어 사전을 이용하여 가장 유사한 핵심어를 찾아 그 핵심어의 의미를 부착한다. 중의성을 가진 고빈도 핵심어 3개와 저빈도 핵심어 3개를 말뭉치에서 선정하여 제안 시스템의 성능을 평가하였다. 실험결과, 수동으로 구축한 말뭉치를 사용하였을 때 약 54.4%의 정확도를 얻었고, 반자동으로 확장한 말뭉치를 사용하였을 때 약 50.0%의 정확도를 얻었다.

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.

열중성자로의 무작위 중성자 특성을 PC로써 측정하는 체계를 개발하고 이를 한국에너지연구소의 TRIGA Mark-II 원자로에 응용하였다. 그 결과 이 체계는 재래의 여러 방법에 비하여 많은 장점을 가지고 있음을 확인하였다. 아직은 한개의 계측기를 사용하였고, 즉발중성자만 고려한 시간 영역에 대하여 autocorrelation과 VTMR 두가지 방법으로 분석하였다. 두 방법의 결과는 서로 잘 일치하였으나 통계적인 신뢰도 면에서는 VTMR이 훨씬 나았고, 특히 임계 근처에서 이것이 두드러졌다. TRIGA Mark-II의 $\beta$/Λ 는 임계에서 -3＄까지는 약 125/초, -4＄이하에서는 약 150/초로 측정되었다.

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.

본 논문에서는 단일 차선표시선 검출 기반 차선 이탈 경보 시스템을 제안한다. 제안하는 방법은 어두운 조명이나 마모로 인하여 좌 우 차선표시선의 동시 검출이 불가능한 경우에도 단일 차선표시선의 검출 및 추적을 통해 강건한 차선이탈 감지를 목표로 한다. 실험을 통해 제안 방법이 한쪽 차선표시선만 검출된 경우에도 차선이탈을 감지하는 것을 확인하였다.

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.

본 연구는 창의·인성 연구소 심벌마크 제작을 목적으로 3가지의 시안을 제시하고자 하였으며, 공통적으로 4C's를 표현하기 위하여 4가지 색상을 사용하였다. 시안1은 재미와 역동성을 자아내어 자유분방함을 표현하였고, 시안2는 사각형 도형의 형태로 정적이고 안정감이 있어 차분함을 유지하고 있다. 마지막으로 시안3은 창의인성 글씨의 자음만을 활용하여 제작하였다.

스마트폰이 출시하기 전 과거 핸드폰의 음악 재생력은 아주 한정적이었기 때문에 MP3 플레이어를 필요로 했으나 스마트폰이 등장하면서 멀티미디어 재생은 필수적인 기능이 되었으며, MP3의 모든 기능이 작동하게 되었다. 그리고 하나의 기기에서 음악 및 멀티미디어 재생의 모든 것이 이루어지기 때문에 편리하지만 스마트폰의 음질 부분에 있어서의 논란은 끊이지 않았다. 본 논문은 스마트폰이 가진 음악 재생기능 중 EQ(Equalizer)를 Right Mark Audio Analyzer 프로그램을 통하여 EQ(Equalizer) 밸런스 조절을 통한 하이 피델리티(High Fidelity)에 가까운 사운드의 재생에 관하여 알아본다.
