Our research is aimed at predicting recent trend and leading technology for the future and providing optimal Nano technology trend information by analyzing Nano technology trend. Under recent global market situation, Users' needs and the technology to meet these needs are changing in real time. At this point, Nano technology also needs measures to reduce cost and enhance efficiency in order not to fall behind the times. Therefore, research like trend analysis which uses search data to satisfy both aspects is required. This research consists of four steps. We collect data and select keywords in step 1, detect trends based on frequency and create visualization in step 2, and perform analysis using data mining in step 3. This research can be used to look for changes of trend from three perspectives. This research conducted analysis on changes of trend in terms of major classification, Nano technology of 30's, and key words which consist of relevant Nano technology. Second, it is possible to provide real-time information. Trend analysis using search data can provide information depending on the continuously changing market situation due to the real-time information which search data includes. Third, through comparative analysis it is possible to establish a useful corporate policy and strategy by apprehending the trend of the United States which has relatively advanced Nano technology. Therefore, trend analysis using search data like this research can suggest proper direction of policy which respond to market change in a real time, can be used as reference material, and can help reduce cost.

In this paper we have evaluated the synthetic speech quality by the proposed TD-PCULI speech synthesis method. For the synthesis we have extracted parameters from the Korean monosyllables through the analysis of speech waveforms in the time domain. We have constructed the Korean data format dictionary for the synthesis-by-rule depending upon the frequencies of the Korean pronunciation large vocabulary dictionary, in which V type syllables are 19, CV type's are 80, VC type's are 30 and CVC type's are 100. And using them we have synthesized various Korean monosyllables, words and sentences. We have tested each 10 syllables selected according to the 4 Korean syllable types with the objective MOS(Mean Opinion Score) evluation method about the 4 items i.e., intelligibility, clearness, loudness, and naturality after selecting random group without the knowledge of them. And also we have tested the possibility to modify a duration and F0 into another forms with changing a duration (i.e., 150msec, 300msec, 500msec, 700msec and 1sec) and a central fundamental frequency(i.e., 80Hz, 118Hz, 140Hz, 170Hz, and 200Hz). As the results of experiments the noises occurred in the course of synthesizing the speech by the rules are removed to be a very clear level and we can find that the prosodic elements can be controled as a good condition.

This research is to figure out how people recognize and perceive on cosmetic attributions of imported brand and domestic brand. In other words, we are trying to analyze the brand images and figure out how they are different in demographic perspective. For this research, this research has been fulfilled from September 20th 2011 to November 5th. We have surveyed women with age between 20's to 50's. With 477 data, we have analyzed by using SPSS 18.0 Version of statistic package. We have used frequency analysis, t-test and one way ANOVA (chi-square test) for data processing method. By comparing and analyzing the 16 attribute types of imported and domestic cosmetics, there were no attention difference on 7 questionaries' but there were attention difference on 9 questionnaires'. 5 questionaries' which show higher recognition on domestic brand of cosmetic than imported brand were shown. 4questionaries' which show higher recognition on imported brand of cosmetic than domestic brand were shown. By examining the different recognitions between domestic brand and imported brand of cosmetics in demographic perspective, it did not show any attentive difference on domestic brand by district residence, age, academic ability, marriage, occupation and monthly income average. But it showed attentive difference on imported cosmetic brand. It showed that people who live in capital region, with younger age and who have not been married have high rate of preference on imported cosmetic brand. It also showed that people who have higher academic ability and with higher monthly income average have high rate of preference on imported cosmetic brand. Especially, specialized job showed highest preference.

The aim of this study is to investigate the usefulness of the multiple-choice name matching test (MC-NMT) in adults with aphasia by comparing the Korean version of the Boston Naming Test (K-BNT) and subsets of the Korean version of the Western Aphasia Battery (K-WAB). Thirty-nine patients who suffer from aphasia participated in the study. All patients were examined by the K-BNT, MC-NMT and K-WAB. The MC-NMT consisted of the 30 original BNT object stimuli which were presented with four response choices (written words) with similar frequency, including one correct and three incorrect responses. Cards containing the drawings were presented to the patient one at time. An item was passed if the patient chose the correct response within 10 seconds. We subdivided two groups into a total group and a low K-BNT group (at and below 15 points). We evaluated the correlation between the K-BNT, MC-NMT score and production, naming, repetition, comprehension, reading and writing scores in subsets of the K-WAB. There was a highly positive correlation between the K-BNT score and naming score of the K-WAB in total patients. However, the MC-NMT was highly correlated with reading scores in the K-WAB. In low score K-BNT patients, the K-BNT strongly correlated with production, naming and repetition scores of the K-WAB. These findings mean that K-BNT reflects motor language function. However, the MC-NMT was strong correlated comprehension, reading and writing of the K-WAB. This finding reflects sensory language function. We suggest that the combination of K-BNT and newly developed MC-NMT will be useful to evaluate speech functions in aphasic patients.

인터넷 이용자의 증가와 함께 이메일 카드의 사용빈도가 급증하고 있다. e 카드는 실시간(real-time)으로 전송되는 장점에 더해 동영상과 효과음을 다중적(multiplex)으로 즐길 수 있는 카드이다. 또한 이용자는 자신의 정서에 따른 선택(alternative)이 가능하다. 이러한 이유로 절은 층에서는 종이카드에서 전자 카드로의 선호도 전이가 뚜렷이 나타나고 있으며 이메일 카드 전문 사이트의 경우 이를 캐릭터 프로모션을 위한 매체로 적극 활용하고 있다. 엽기토끼 '마시마로'가 플래시 애니메이션으로 성공한 이후, 플래시 카드는 캐릭터 비즈니스에 있어 중요한 매체로 인식되어 적극 활용되면서 인터넷 환경을 이루는 주요한 시각물로 자리 잡고 있다. 본 연구는 e 카드 가운데 이용자의 인기를 끌고 있는 플래시 카드를 위주로 하고 이것이 사용자에게 주는 미감의 동인에 대한 고찰로써, 표현 속에 내재되어 있는 의미를 분석하고 이를 엔트로피 개념으로 설명하였다. 즉 애니메이션의 내용은 단순 구성에 따른 단순성 추구에, 표현 형식은 일상성에서의 이탈로부터 얻어지는 이화효과에 기반을 둔 것으로 요약하고, 이 두가지에서 산출되는 것은 구조적 주제의 이완에 따른 긴장 감소의 즐거움으로 보고 미감의 동인을 여기에 설정하였다.

국내 대다수의 학술지는 논문 제출시 한글로 쓴 논문 제목과 함께 영어로 된 논문 제목을 제출할 것을 요구한다. 그러나 일반적으로 논문작성자나 논문 심사자들 조차도 영문 논문 제목에 큰 비중을 두지 않는다. 본 논문은 미국과 한국에서 출판된 학술지의 논문제목에서 국가간 문화적 특성과 차이를 알아보기 위한 연구이다. Scopus와 RISS 데이터베이스를 이용하여 사회과학분야와 관련된 논문제목들을 발췌하여 이 연구를 진행하였다. 연구 대상이 된 논문의 제목은 제목의 길이, 종류 및 n-gram 문구 등의 여러 유형을 사용하여 분석 및 비교하였고, 샘플 논문 제목을 분석한 결과, 한글로 작성된 학술지 논문의 제목에서는 특별히 선호되는 단어와 구문의 유형을 발견하였다. 이러한 유형들의 관습적 사용들로써 논문의 제목에서 국가간의 문화적 차이가 나타난다는 결과를 도출하였다. 이 연구는 영문 제목을 붙일 때에 국내 논문에서 보여주는 전형적인 양상을 지적하고 국가간의 문화적 차이에 대해 좀더 인식하고 염두 해야 한다는 점을 주장한다.

As the demand for slim laptops requires ion'-height optical disc drives, vibration problems of optical disc drives are of great concern. Additionally, with the decrease of a track width and a depth of focus in high density drives, studies on vibration resonance between mechanical parts become more important. From the vibration point of view, the performance of optical disc drives is closely related with the relative displacement between a disc and an objective lens which is controlled by servo mechanism. In other words, to read and write data properly, the relative displacement between an optical disc and an objective lens should be within a certain limit. The relative displacement is dependent on not only an anti-vibration mechanism design but also servo control capability. Good servo controls can make compensation for poor mechanisms, and vice versa. In a usual development process, robustness of the anti-vibration mechanism is always verified with the servo control of an objective lens. Engineers partially modify servo gain margin in case of a data reading error. This modification cannot correct the data reading error occasionally and the mechanism should be redesigned more robustly. Therefore it is necessary to verify a mechanism with respect to the possible servo gain plot. In this study we propose the experimental verification method far anti-vibration mechanism with respect to the existing servo gain plot. This method verifies axial vibration characteristics of optical disc drives on the basis of transmissibility. Using this method, we verified our mechanism and modified the mechanism for better anti-vibration characteristics.
