This study was conducted to find information on the university's image from words related to 'Korea National College of Agriculture and Fisheries (KNCAF)' in Naver News. For this purpose, word frequency analysis, TF-IDF evaluation and semantic network analysis were performed using web crawling technology. In word frequency analysis, 'agriculture', 'education', 'support', 'farmer', 'youth', 'university', 'business', 'rural', 'CEO' were important words. In the TF-IDF evaluation, the key words were 'farmer', 'dron', 'agricultural and livestock food department', 'Jeonbuk', 'young farmer', 'agriculture', 'Chonju', 'university', 'device', 'spreading'. In the semantic network analysis, the Bigrams showed high correlations in the order of 'youth' - 'farmer', 'digital' - 'agriculture', 'farming' - 'settlement', 'agriculture' - 'rural', 'digital' - 'turnover'. As a result of evaluating the importance of keywords as five central index, 'agriculture' ranked first. And the keywords in the second place of the centrality index were 'farmers' (Cc, Cb), 'education' (Cd, Cp) and 'future' (Ce). The sperman's rank correlation coefficient by centrality index showed the most similar rank between Degree centrality and Pagerank centrality. The KNCAF articles of Naver News were used as important words such as 'agriculture', 'education', 'support', 'farmer', 'youth' in terms of word frequency. However, in the evaluation including document frequency, the words such as 'farmer', 'dron', 'Ministry of Agriculture, Food and Rural Affairs', 'Jeonbuk', and 'young farmers' were found to be key words. The centrality analysis considering the network connectivity between words was suitable for evaluation by Cd and Cp. And the words with strong centrality were 'agriculture', 'education', 'future', 'farmer', 'digital', 'support', 'utilization'.

The purpose of this paper is to provide basic data for development of Korean teaching programs for immigrant women from multicultural families through the acoustic analysis of their prosodic phrasing and intonation pattern. The results showed that immigrant women showed some differences in most of the prosodic characteristics from a Korean women's group: Immigrant women realized the first word of a sentence in an intonational phrase while Korean women did in an accentual phrase. They also haven't yet correctly learned the tone type of the first of an accentual phrase which differs depending on the type of its first segment yet. As a result, they showed many diverse intonation patterns compared to Korean women. Furthermore, the immigrant women's groups showed some differences between them in a few prosodic characteristics. Philippine women, whose residence duration in Korea is relatively longer than that of Vietnamese women, were more similar to Korean women: Vietnamese women read a sentence with a larger number of intonational phrases than Philippine women did. And they realized sentence-final boundary tone of a yes-no question not only in 'H%' but also in 'HL%' while, like Korean women, Philippine women did only in 'H%'.

Objective & Method : We investigated the identity of chilsonparik which is written in Hwangjenaekyung and claimed by traditional scholars, and drew the following conclusions. Result & Conclusion : The word "Chilsonparik"(七損八益) is written in Hwangjenaekyung(黃帝內經). However the exact meaning of "Chilsonparik" doesn't appear in the Hwangjenaekyung so several scholars were studying to find out its true meaning. In 1973, a book "Cheonhajidodam"(天下至道談) was unearthed in the mawangtoe Han Tomb in Hunan province. This book "Cheonhajidodam" had a detailed description of "Chilsonparik", and its contents were similar to those of the "Hwangjenaekyung". In this sense, the sentences of "Hwangjenaekyung" is likely to have copied the contents of "Cheonhajidodam" or have quoted the same book, which makes it possible to interpret "Chilsonparik" in the "Hwangjenaekyung" relying on the description of "Chilsonparik" from the "Cheonhajidodam". Based on "Cheonhajidodam" the "Chilson" refers to "Seven ways of sexual intercourse that bring harm to the human body" and "Parik" refers to "Eight ways of sexual intercourse that bring benefit to the human body". The description of "Chilsonparik" in "Cheonhajidodam" is way more specific than the interpretation of the posterity scholars of the later generations. It is a also seen that the contents of the "Cheonhajidodam is appropriate as the "Hwangjenaekyung" depicts the "Chilsonparik" in concrete acts and ways. It is thought that the explanation of "Cheonhajidodam" gave correct answers to the "Chilsonparik" that was left as a question for us.

Forecasting of box office performance after a film release is very important, from the viewpoint of increase profitability by reducing the production cost and the marketing cost. Analysis of psychological factors such as word-of-mouth and expert assessment is essential, but hard to perform due to the difficulties of data collection. Information technology such as web crawling and text mining can help to overcome this situation. For effective text mining, categorization of objects is required. In this perspective, the objective of this study is to provide a framework for classifying films according to their characteristics. Data including psychological factors are collected from Web sites using the web crawling. A clustering analysis is conducted to classify films and a series of one-way ANOVA analysis are conducted to statistically verify the differences of characteristics among groups. The result of the cluster analysis based on the review and revenues shows that the films can be categorized into four distinct groups and the differences of characteristics are statistically significant. The first group is high sales of the box office and the number of clicks on reviews is higher than other groups. The characteristic of the second group is similar with the 1st group, while the length of review is longer and the box office sales are not good. The third group's audiences prefer to documentaries and animations and the number of comments and interests are significantly lower than other groups. The last group prefer to criminal, thriller and suspense genre. Correspondence analysis is also conducted to match the groups and intrinsic characteristics of films such as genre, movie rating and nation.

In this rarer, we introduce a new Fuzzy Polynomial Neural Networks (FPNNs)-like structure whose neuron is based on the Fuzzy Set-based Fuzzy Inference System (FS-FIS) and is different from that of FPNNs based on the Fuzzy relation-based Fuzzy Inference System (FR-FIS) and discuss the ability of the new FPNNs-like structurenamed Fuzzy Set-based Polynomial Neural Networks (FSPNN). The premise parts of their fuzzy rules are not identical, while the consequent parts of the both Networks (such as FPNN and FSPNN) are identical. This difference results from the angle of a viewpoint of partition of input space of system. In other word, from a point of view of FS-FIS, the input variables are mutually independent under input space of system, while from a viewpoint of FR-FIS they are related each other. In considering the structures of FPNN-like networks such as FPNN and FSPNN, they are almost similar. Therefore they have the same shortcomings as well as the same virtues on structural side. The proposed design procedure for networks' architecture involves the selection of appropriate nodes with specific local characteristics such as the number of input variables, the order of the polynomial that is constant, linear, quadratic, or modified quadratic functions being viewed as the consequent part of fuzzy rules, and a collection of the specific subset of input variables. On the parameter optimization phase, we adopt Information Granulation (IG) based on HCM clustering algorithm and a standard least square method-based learning. Through the consecutive process of such structural and parametric optimization, an optimized and flexible fuzzy neural network is generated in a dynamic fashion. To evaluate the performance of the genetically optimized FSPNN (gFSPNN), the model is experimented with using gas furnace process dataset.

The performance of underwater acoustic communication systems is sensitive to inter-symbol interference caused by delay spread developed from multipath signal propagation. The multipath nature of underwater channels causes signal distortion and error floor. In order to improve the performance, it is necessary to employ an iterative coding scheme. Of the various iterative coding schemes, turbo code and convolutional code based on the BCJR algorithm have recently dominated this application. In this study, the performance of iterative codes based on turbo equalizers with equivalent coding rates and similar code word lengths were analyzed. Underwater acoustic communication system experiments using these two coding techniques were conducted on Kyeong-chun Lake in Munkyeong City. The distance between the transmitter and receiver was 400 m, and the data transfer rate was 1 Kbps. The experimental results revealed that the performance of turbo codes is better for channeling than that of convolutional codes that use a BCJR decoding algorithm.

The voice has distinguishable acoustic properties of speaker as well as transmitting information. The speaker recognition is the method to figures out who speaks the words through acoustic differences between speakers. The speaker recognition is roughly divided two kinds of categories: speaker verification and identification. The speaker verification is the method which verifies speaker himself based on only one's voice. Otherwise, the speaker identification is the method to find speaker by searching most similar model in the database previously consisted of multiple subordinate sentences. This paper composes feature vector from extracting MFCC coefficients and uses the dynamic time warping algorithm to compare the similarity between features. In order to describe common characteristic based on phonological features of spoken words, two subordinate sentences for each speaker are used as the training data. Thus, it is possible to identify the speaker who didn't say the same word which is previously stored in the database.

This study looks into the Korean traditional costume formation and the thoughts of the Korean people that form the foundation of that Korean traditional costume formation. And the goal of this study is in linking the thoughts and formative characteristics reflected in the Korean traditional costume formation to the fractal geometry, in an attempt to reveal correlation between Korean traditional costume formation which have existed for thousands of years to contemporary science of the West. The fractal theory that appeared as the new paradigm of contemporary science displayed similarities with the traditional ideologies of Korea, and the fact that formation principles of fractal appear in the formation of Korean costume, formed based on the Korean ideologies, show magnanimous capacity of the traditional Korean culture. When we look at the concept of fractal, the word fractal refers to the structure in which the shape repeats, where small structure is similar to the whole structure in form in endlessly repeating structure. In other words, 'fractal' means a structure that geometrically untangles the concept of 'self-similarity' which possesses the same shape in parts and in whole, and its major characteristics include 'self-similarity', 'circularity' and 'repeatability'. Korean costumes were formed based on the Han-thoughts, with a structure that possesses parts within the whole and the whole within parts, in accordance with the self-similarity theory of 'fractal'. This study compared studied fractal phenomenon which appear in formation characteristics of Korean traditional costume, which were formed based on the Korean traditional ideology, in other words, Korean costume formation and formation principles of fractal geometry were compared studied.

Due to multidisciplinary characteristic of the Interior Design field, it has developed into complex interdisciplinary field. Therefore Interior Design field has grown and established its major trends dependent upon other related field of study. With this perspective in mind, esthetics on Interior Design has to be treated in similar manner. In modem architects or artists have defined the terminology 'object' theoretical principle where by unable to distinguish between 'object's type' and 'objects', Presently, the term 'object' became a trend word. In order to confront misconception of the idea of 'Objectification', some people definition as reflection of this complex society. In this paper, it will establish a solid groundwork for a discussion on Objectification. The initial approach will deal with Le Corbusier and esthetics, which is the center of argument. By reviewing theoretical background of the related modern art, the paper discusses about the relationship between Le Corbusier and esthetics. Subsequently, the discussion about the criterions necessary to define object is provided. This paper only suggests a methodology of analyzing a trend in Interior Design. The condition to define Objectification in Interior Design, which is a result of the reviewing process on esthetics, can be concluded as 'modeling form(transformation of morphological meaning with change wrought by causing a visual reaction)', 'mixtures and modification of materials(transformation and spontaneity through mixing materials)' and 'elements greatly influence space' of the Interior Design.

$\ll$Yongchu(靈樞)$\gg$ is completed as a result of gathering several treatises about oriental medicine in B.C. 3c ~ A.D. 1c, and esteemed as a bible of oriental medicine, especially very much quoted in acupuncture fields. But the name of $\ll$Yongchu(靈樞)$\gg$ wasn't in existence at that time. Until A.D. 3c, it had been named after $\ll$Guguen(九券)$\gg$, given it's number of volumes, and since then mainly named after $\ll$Chimgueng(針經)$\gg$, given a word of the first volume. After A.D. 6c, under the influence of Taoism(道家), it was titled $\ll$Yongchu(靈樞)$\gg$, $\ll$Guhe(九墟)$\gg$, $\ll$Gureong(九靈)$\gg$ etc. Yongchu(靈樞), guhe(九墟), gureong(九靈) are words which is connected with Taoism(道家). In 1155, Sung Sa(史崧) published $\ll$Yongchu(靈樞)$\gg$, whim became a textbook of oriental medicine, so other titles disappeared since then. $\ll$Yongchu(靈樞)$\gg$, $\ll$Guhe(九墟)$\gg$, $\ll$Gureong(九靈)$\gg$, $\ll$Guguen(九卷)$\gg$, $\ll$Chimgueng(針經)$\gg$ are not the same book, but the contents are almost similar, and some letters are different. Especially the textbook, pubished by Sasung(史崧), had been related to the $\ll$Chimgyeng(針經)$\gg$, delivered to North-Song(北宋) dynasty by Jong-Gag Haung(黃宗慤), an envoy of an ancient Korean state(918-1392). So I expect to progress the study of medical exchange about it in the future.
