For studying on the actual condition of the oral health control of the old there were invastigations on the Questions with the college of the old in Chonbuk as the central figure from June 1 to June 30, 1998 and the analyses about the frequency and the mutual relation through χ²-test. The results are as follow: 1. According to the result of the investigation into the actual condition about the oral health of the old, two times a day in the frequency of tooth brush per day was the highest at the rate of 50.35％, the use of dentifrice was 45.4％, and the exchanging time of tooth-brush after six months was the highest at the rate of 19.7％. And 96.1％ didn't use dental floss and 73.6％ didn't do scaling. It is thought that since 50％ used tooth sticks and match sticks we have to inform the old of the necessity of dental plague and period oral examination. 2. In oral health situation, it showed that the number of people who were very week was the highest at the rate of 37％ and there was the mutual relation between the use of tooth sticks and match sticks and present situation of oral health. And 54.93％ visited the dental clinic wethin a year, and 22.3％ among them made full denture. There was the mutual relation between the visit of dental clinic within a year and the consultation content and the number of people who teld that the consultation expense was very expensive was the higest at the rate of 27.8％ and 87％ didn't experience the oral education. So it is thought that we have to make an systematic education about the oral to the old and inform them of the necessity of oral health control. 3. We think it needs the establishment and plane of the systematic basis material and the oral education which is necessary in oral public industry for the dental preventive suitable to the characteristic of the old.

The purpose of this paper was to explore the narrative strategy of storytelling advertisement videos for a beer brand Heineken. Heineken was one of the most active advertisers who had made very impressive ad videos. The author selected five story driven advertisement videos which had been most frequently watched by Internet viewers. Those were "The Insider", "Odyssey 2011", "Heineken lip gross", "Italy Activation Milan AC vs. Real Madrid", "the Match". The five selected videos have 90 second running time. The target videos were repeatedly watched and the expected key image cuts and key verbal copies were captured as well. To categorize the narrative structure and key copies of each video, Fog, Budtz & Yakaboylu's four element model of storytelling and Gustav Freytag's three act structure or five stage model of a plot were exploited as underlying theories. Most of the ad videos had clear boundary between or among the stages of the plot and used emotional appeals including humor and sexual appeals. This paper found that the target videos used visual rhetorics to enhance the viewers' persuasion and comprehension. It also revealed that the target videos took advantage of football match as an emotional engagement to get ad viewers closely banded with Heineken.

Continued observation of ARGO floats for years(about 4 years) makes the conductivity sensor more vulnerable to fouling by marine life and associated drift in salinity measurements. In this paper, we address this issue by making use of floats deployed in different years. Floats deployed in the East Sea and the Indian Ocean are examined to find out float-to-float match-ups in such a way that an older float pops up simultaneously with a newer deployment (with tolerable space-time difference). A time difference of less than five days and space difference of less than 100km are considered for the match-up data sets. For analysis of the salinity drift under the stable water mass, observations of the floats from deepest water masses have been used. From the cross-check of ARGO floats in the East Sea and the Indian Ocean, it is found that there is a systematic drift in the older float compared to later deployments. All drift results, consistently show negative bias indicating the typical nature of drift from fouled sensors. However, the drift is much less than 0.01, the specified accuracy of ARGO program.

In this paper, we present a non-static color histogram method to retrieve clothing images that are similar to a query clothing. Given clothing area, our method automatically extracts major colors by using the octree-based quantization approach[16]. Then, a color palette that is composed of the major colors is generated. The feature of each clothing, which can be either a query or a database clothing image, is represented as a color histogram based on its color palette. We define the match color bins between two possibly different color palettes, and unify the color palettes by merging or deleting some color bins if necessary. The similarity between two histograms is measured by using the weighted Euclidean distance between the match color bins, where the weight is derived from the frequency of each bin. We compare our method with previous histogram matching methods through experiments. Compared to HSV cumulative histogram-based approach, our method improves the retrieval precision by 13.7 % with less number of color bins.

In this paper, an ascheme is proposed for multiuser underwater acoustic communication by using the multi-chirp rate signals. It differs from the well known TDMA (Time Division Multiple Access), FDMA (Frequency Division Multiple Access) or CDMA (Code Division Multiple Access), by assigning each users with different chirp-rate carriers instead of the time, frequency or PN code. Multi-chirp rate signals can be separated from each other by FrFT (Fractional Fourier Transform), which can be regarded as the chirp-based decomposing, and superior to the match filter in the underwater acoustic channel. VTRM (Virtual Time Reverse Mirror) is applied into the system to alleviate the ISI caused by the multipatch and make the equalization more simple. Results of computer simulations and pool experiments prove that the proposed multiuser underwater acoustic communication based on the multi-chirp rate exhibit well performance. Outfield experments carrie out in Xiamen Port show that using about 10 kHz bandwidth, four users could communicate at the same time with 425 bps with low BER and can match the UAC application.

특징 기반 영상 인식 방법은 객체의 특징을 이용하므로 템플릿 정합에 비해 고속으로 수행될 수 있다. 불변 특징 기반의 파노라마 생성은 영상 인식의 한 응용으로서, 두 영상 간의 특징점 정합에 많은 처리 시간이 필요하다. 본 논문에서는 특징 강도 정보를 이용하여 특징점 정합 속도를 향상시키는 방법을 제안한다. SURF 알고리즘으로 특징점들을 추출한 후, 특징 강도 정보를 계산하여 강한 특징점들을 선택하여 특징 정합에 사용한다. 특징 강도가 강한 특징점들은 그렇지 않은 특징점들 보다 더 의미 있다고 볼 수 있다. 실험에서 $320{\times}240$ 크기의 칼라 영상에 대해 제안한 방법은 특징 강도 정보를 사용하지 않았을 때보다 40% 이상 처리 속도의 향상을 보였다.

Case-based reasoning is emerging as a leading methodology for the application of artificial intelligence. CBR is a reasoning methodology that exploits similar experienced solutions, in the form of past cases, to solve new problems. Hybrid model achieves some convergence of the wide proliferation of credit evaluation modeling. As a result, Hybrid model showed that proposed methodology classify more accurately than any of techniques individually do. It is confirmed that proposed methodology predicts significantly better than individual techniques and the other combining methodologies. The objective of the proposed approach is to determines a set of weighting values that can best formalize the match between the input case and the previously stored cases and integrates fuzzy sit concepts into the case indexing and retrieval process. The GA is used to search for the best set of weighting values that are able to promote the association consistency among the cases. The fitness value in this study is defined as the number of old cases whose solutions match the input cases solution. In order to obtain the fitness value, many procedures have to be executed beforehand. Also this study tries to transform financial values into category ones using fuzzy logic approach fur performance of credit evaluation. Fuzzy set theory allows numerical features to be converted into fuzzy terms to simplify the matching process, and allows greater flexibility in the retrieval of candidate cases. Our proposed model is to apply an intelligent system for bankruptcy prediction.

Using biometrics to verify a person's identity has several advantages over the present practice of personal identification numbers (PINs) and passwords. To gain maximum security in a verification system using biometrics, the computation of the verification as well as the storing of the biometric pattern has to take place in a smart card. However, there is an open issue of integrating biometrics into a smart card because of its limited resources (processing power and memory space). In this paper, we propose a speaker verification algorithm using a support vector machine (SVM) with a very few features, and implemented it on a 32-bit smart card. The proposed algorithm can reduce the required memory space by a factor of more than 100 and can be executed in real-time. Also, we propose a hardware design for the algorithm on a field-programmable gate array (FPGA)-based platform. Based on the experimental results, our SVM solution can provide superior performance over typical speaker verification solutions. Furthermore, our FPGA-based solution can achieve a speed-up of 50 times over a software-based solution.

Tubing adapter is a key connection device in Gas-Tight Deep-Sea Water Sampler (GTWS). The sealing performance of the tubing adapter directly affects the GTWS's overall gas tightness. Tubing adapters with good sealing performance can ensure the transmission of seawater samples without gas leakage and can be repeatedly used. However, the sealing performance of tubing adapters made of different materials was not studied sufficiently. With the research discussed in this paper, the materials match schemes of the tubing adapters were proposed. With non-linear finite element contact analysis and sea trials in the South China Sea, it is expected that the recommended materials match schemes not only meet the requirements of tubing adapters' sealing performance but also provide the feasible options for the following research on tubing adapters in GTWS.
