New environment change of electric power system focused in consumer's energy supply and demand. But electric power reliability preservation and reliability improvement countermeasure also need for long-term. It is need that change equipments that is composing electric power system in well-timed time and by maintaining, prevent breakdown beforehand and prevent consumer's power interruption by equipment fail. However, as only quantitative estimation is available by reliability estimation method that is presented in existing, it is no to use in dictionary fault prevention. Therefore, applied optimum reliability preservation through existent equipment fault data analysis of electric power system in equipment replace side, and this when maintain equipment replace of electric power system for reliability preservation using responsiveness analysis to base ordering evaluate. In existing about main equipment plain that this paper is power system the valued failure rate use this by score and precedence of electric power system equipment for replace of system considered expense.

Our goal is to build the system which collects tweets from Twitter, analyzes the sentiment of each tweet, and helps users build a sentiment tagged corpus semi-automatically. After collecting tweets with the Twitter API, we analyzes the sentiments of them with a sentiment dictionary. With the proposed system, users can verify the results of the system and can insert new sentimental words or dependency relations where sentiment information exist. Sentiment information is tagged with the JSON structure which is useful for building or accessing the corpus. With a test set, the system shows about 76% on the accuracy in analysing the sentiments of sentences as positive, neutral, or negative.

In the mold parts industry, customers typically place orders for order-made parts with some changes to the design specifications of ready-made parts within the extent of the manufacturing capability of the supplier. Being customized for ready-made parts, existing e-Catalog systems cannot support the above trade pattern. To solve this problem, an ETO (engineering-to-order) method is proposed here, enabling the trade of order-made parts in an e-Catalog system by utilizing the design and manufacturing knowledge of the part suppliers. After addressing technological challenges and solutions, we briefly describe application of the ETO method to two types of mold parts - ejector pins and mold bases.

From the hazard which it prepares in the hazards increase which it follows in information demand augmentation of information technical development and the consumer from inside systematizing integrity and solubility of information technological resources. inside against a confidentiality. The control against information and a system and a data outside is demanded. From the dissertation which it sees demand function and the structure which do information technical risk management system development it will be able to manage the danger which it infiltrates with the root which is various overview in hazard necessity it investigated the inside and outside of the country instance in the center and it analyzed. And it plans the dangerous civil official integrated process model ultimately as against a hazards it will be able to prepare in the dictionary in order, it put the place objective which it induces.

In order to meet the requirements of background change, illumination variation, moving shadow interference and high accuracy in object detection of moving camera, and strive for real-time and high efficiency, this paper presents an object detection algorithm based on sparse approximation recursion and sparse coding migration in subspace. First, low-rank sparse decomposition is used to reduce the dimension of the data. Combining with dictionary sparse representation, the computational model is established by the recursive formula of sparse approximation with the video sequences taken as subspace sets. And the moving object is calculated by the background difference method, which effectively reduces the computational complexity and running time. According to the idea of sparse coding migration, the above operations are carried out in the down-sampling space to further reduce the requirements of computational complexity and memory storage, and this will be adapt to multi-scale target objects and overcome the impact of large anomaly areas. Finally, experiments are carried out on VDAO datasets containing 59 sets of videos. The experimental results show that the algorithm can detect moving object effectively in the moving camera with uniform speed, not only in terms of low computational complexity but also in terms of low storage requirements, so that our proposed algorithm is suitable for detection systems with high real-time requirements.

There are two types of mold parts, ready-made standard parts and ETO (Engineered-to-Order) parts, the latter are of increasing importance to manufacturers. However, the ETO parts require more engineering support and communication than the ready-made standard parts. Existing e-Catalog modules provide classification structures of products that allow customers to select products based on their needs, and the trade begins with the provided specification. However, machine parts or mold parts have different purchasing patterns. Customers do not purchase the ready-made standard parts offered by an e-Catalog. They usually (1) add own options to the provided specifications or (2) change specification items such as length. To support these trades, a new e-Catalog system is proposed. The proposed system is based on the product design process and the specification selection process in addition to the parts classification structure.

Although features, core element of marine GIS in many application, are same things users have difficulty in using them on account of varying according to method of classification. Accordingly feature cataloguing in accordance with the standard is the trend of the modem world. In this article we have became familiar with ISO 19110 - Methodology for Feature Cataloguing, we was able to discuss element and definition of features for the purpose of Marine GIS's activation. Through the result of study, we presented the methodology of Marine GIS feature cataloguing.

The purpose of this study is to research into the relationship between the clothing purchase practices of high school girls in Seoul and their social stratification. For the survey of social stratification, the information of the monthly income of the households were extracted from the Annual Report of the City-Household in the Economic Planning Board : as for the occupations of patriarches, the groups of occupations were extracted from the Census of the Population & House in the Economic Planning Board and the types of occupations from the Korea Professional Dictionary in the Labor Ministry. The survey of clothing purchase practices is based on Ryan's Clothing: A Study in Human Behavior. The questionnaires were distributed to the seven girls' high schools in Seoul. The data from 354 respondents was analyzed by Pearsons'r, ANOVA and $x^2$ test. The Results were: 1. There was a significant relationship between clothing purchase practices variables and their social stratification. 2. There were differences in clothing purchase practices variables according to the social stratification. 3. There were significant relationships among the three clothing purchase practices variables.

This paper a framework and method for resolving word sense disambiguation and present the results. In this work, WordNet is used for two different purposes: one as a dictionary and the other as an ontology, containing the hierarchical structure, representing hypernym-hyponym relations. The advantage of this approach is twofold. First, it provides a very simple method that is easily implemented. Second, we do not suffer from the lack of large corpus data which would have been necessary in a statistical method. In the future this can be extended to incorporate other relations, such as synonyms, meronyms, and antonyms.

The purpose of this study is to present a scheme to encode all possible lexical entities in dictionaries, glossaries, encyclopedias, and thesaurus, etc. First, it discussed the nature and structure of dictionaries. Second, two current major terminological data encoding schemes, MARTIF and TEI were analyzed in terms of their flexibility for extension to encompass all lexical entities. Third, an integrated microstructure of dictionaries was presented and compared with the MARTIF and TEI for print dictionaries. Then, the need and 17 suggestions for extended MARTIF and TEI formats were addressed with specific cases, which combined with the suggestions from two studies concerning MARTIF and TEI DTD modification for the markup of Korean dictionary entries.
