Logs from various security system can reveal the attack trials for accessing private data without authorization. The logs can be a kind of confidence deriving factors that a certain IP address is involved in the trial. This paper presents a rule-based expert system for derivation of privacy violation confidence using various security systems. Generally, security manager analyzes and synthesizes the log information from various security systems about a certain IP address to find the relevance with privacy violation cases. The security managers' knowledge handling various log information can be transformed into rules for automation of the log analysis and synthesis. Especially, the coverage of log analysis for personal information leakage is not too broad when we compare with the analysis of various intrusion trials. Thus, the number of rules that we should author is relatively small. In this paper, we have derived correlation among logs from IDS, Firewall and Webserver in the view point of privacy protection and implemented a rule-based expert system based on the derived correlation. Consequently, we defined a method for calculating the score which represents the relevance between IP address and privacy violation. The UI(User Interface) expert system has a capability of managing the rule set such as insertion, deletion and update.

An expert system is developed which can design the power transmission involute cylindrical gears on the basis of strength and durability. Bending strength, surface durability, scoring, and wear probability are considered as the basis. The basic components of the expert system are knowledge base, inference engine, and working memory. The knowledges in knowledge base are classified hierarchically into the knowledges used in selection of gear type, selection of materials, and determination of K factor and are represented by rules. In the inference engine two inference methods are implemented with the depth first search method. For-ward chaining method is introduced in the selection of gear type and materials and in the determination of K factor. Backward chaining method is introduced in the detailed design of module and face width in accordance with the validation of strength. And inference efficiency is achieved by constructing the part needing a lot of numerical calculations in strength estimation separately from inference mechanism. The working memory is established to save the results during inference temporarily. In addition, design database of past design results is built for consultation during design and knowledge acquisition facility, explanation facility, and user interface are included for the usefulness of user. This expert system is written with the PROLOG programming language and the FORTRAN language in numerical calculation part which interfaced with PROLOG and can also be executed on IBM-PC compatible computer operated by MS-DOS alone.

Inference engine that performs the brain of software agent in next generation's web with various standards based on standard language of the web, XML has to understand SWRL (Semantic Web Rule Language) that is a language to express the rule in the Semantic Web. In this research, we want to develop a forward inference engine, SMART-F (SeMantic web Agent Reasoning Tools-Forward chaining inference engine) that uses SWRL as a rule express method, and OWL as a fact express method. In the traditional inference field, the Rete algorithm that improves effectiveness of forward rule inference by converting if-then rules to network structure is often used for forward inference. To apply this to the Semantic Web, we analyze the required functions for the SWRL-based forward inference, and design the forward inference algorithm that reflects required functions of next generation's Semantic Web deducted by Rete algorithm. And then, to secure each platform's independence and portability in the ubiquitous environment and overcome the gap of performance, we developed management tool of fact and rule base and forward inference engine. This is compatible with fact and rule base of SMART-B that was developed. So, this maximizes a practical use of knowledge in the next generation's Web environment.

In this article the structure of modern Russian humor is analyzed on the basis of some theories: bi-sociation theory (Koestler 1964), semantic script theory of verbal humor, using the concept of semantic presupposition, pragmatic felicity condition (Searle 1969; Levinson 1983) and grammatical rules (Chomsky 1965). Up to now the listed former theories were not examined and less analyzed by the semantic structure in the study of the structure of Russian humor(HcaeBa 1969; 3 $a_{OPHOB}$ 1991; 1992). Kreps (1981), who analyzed the works of Zoschenko, presented 21 types of humor, using the term 'humoreme'(Kpenc 1981, 36-37). These types are the list of the available means of humor that work not in the base of semantic criteria, but in the base of means of literary rhetoric. Kreps presented types of humor means, such as contradiction, antonymic substitution, macaronic speech and correlation of humoremes in the various types of humor. Apart from Kreps, Manakov (MaHaKOB 1986, 61-79) also studied these problems. He also set the system of the basic types of humor. Manakov introduced the linguistic means of humor of some Russian writers: Gogol, Tchechov. The means that Manakov showed with detailed examples, are trope, epithet, comic comparison, comic metaphor, comic periphrasis, euphemism, pun, zeugma, comic toponym, comic onomatopoeia, mania of foreign vocabulary, folk etymology, dialect etc. But these studies don't explain why these means make the works humorous. An, B.p tried to answer this question (안병팔 1997 a; b). An B.p. explains contexts of humor through the Release theory, the Superiority theory and the Incongruity theory. An, B.p. explained the process of deviation from the grammatical norms through morpho-syntactic and lexical means. But in these studies the humor was not analyzed by the semantic criteria. In order to linguistically evaluate various means of humor formation, it is necessary to elicit its deep structure, which makes it possible to research the formation and interpretation of humor. For this purpose this article, being based on the Incongruity theory, defined the structure of humor as negation of presupposition. Of course the former traditional studies also well shared the concept of 'contradiction' and 'contrast' of humor structure, but they didn't explain the structure by semantic differential features. This study, analyzing the works of' Zadornov, M., tried to note that through the negation of semantic presupposition the structure of contradiction is formed with semantic differential features on the semantic, syntactic or lexical dimensions.

Intense competition for resources has forced many countries pay attention to their eyes to the ocean. Therefore, the disputes and the conflict over the delimitation of the EEZ and continental shelf will be sharpened. Since 1982 Law of the Sea Convention, Korea has opened the talks with Japan and China to discuss the boundary issues as the adjacent water zone is less than 400 miles between Korea and Japan and Korea and China. This study is to review the important rules and techniques for the delimitation of the maritime boundary which have defined in the Law of the Sea Convention and IHO-51 technical guide and to figure out how to build the maritime delimitation GIS DB to negotiate effectively with the neighboring countries. Definition of the base point and baseline will be the utmost important concept to delimit the ocean boundary. The policy makers and the specialists who prepare for the international negotiation meeting between the countries have to be ready to draw the maritime boundary for our best interest under the Law of the Sea Convention. The negotiation strategies and the principles can be made with the concrete and reliable database relevant to maritime boundary issues. So effective and fast strategic decision for negotiation can only be made based on maritime boundary delimitation GIS DB.

Companies do not be resolved by the FTA services of external aid should be operational by assigning dedicated personnel inside the company. FTA is a choice, not an essential trade agreement requirements. If the exporter contracts to provide a certificate of origin in trade agreements, it shall issue a certificate of origin of goods originating management is performed. When considering the future trend of spreading wide FTA, it should be extended to one year to take advantage of the FTA Certificate of Origin environments utilizing a comprehensive environment for regional countries that require proof of origin between certain countries, such as current. FTA utilization of the future is to utilize the GVC(Global Value Chain) efficiently. In other words, the expansion of the consumer market and take advantage of an efficient production base across borders. These environmental changes are needed development of the FTA utilization promotion and FTA experts. The experts studying how to procure raw materials or intermediate goods exports in a variety of regional foreign countries, to meet the rules of origin is required for a successful FTA utilization. One of the objectives of Origin managers are qualified experts in the country of origin can take advantage of the FTA plan. Therefore, managers of origin shall collect their ability to expand the understanding and information about the industry as an international business perspective beyond the Certificate of Origin. In addition, it should be in their best learning expertise for the introduction and development of country of origin control system in an effort to effectively perform its international FTA utilization. Once the FTA is more widespread in the future and build a common origin information it must not be disconnected until the export enterprises from terminal manufacturers systematically. Therefore origin management is preferred by expanding the knowledge base of teaching and learning in the common sense to the universal subject of specialization from professional schools to promote the relevant departments so that they can be opened in a college or university. An FTA hub linking East and West, also need the confidence that in order to become a center of Glabal Supply Chain Using an FTA Certificate of Origin and stable environment for importers to import products from the country offers. Certificate of Origin and all of them thoroughly exporters and companies related to the administration of origin and should create an atmosphere that can effectively respond to the origin verification. Korea shall endeavor to elicit a geopolitical value (FTA Hub), as well as securing a competitive advantage in the global industry leverage, trading at a reasonable price competitive products thereby enhancing production and economic growth through the FTA.

Mechanization is the characteristic of the industrial era and computerization is the characteristic of the Information Era. Now we are facing on the transition from Industrial Era to information Era. Established the National Geo-spatial Data Infrastructures is the fundamental base for information society and is one part of the national basic economic development plan. From 1980's China started his successful transition from traditional methods to high-tech based mapping. China has laid out a high accuracy national GPS (global Positioning System) network, and completed the geographic information databases for scale of 1:1million and 1:250,000. Now it is working on the databases for scales of 1:50,000 and 1:10,000, the world highest level. The massive national programmed has been dubbed "Digital China," since it involves massive quantities of digitized geographical information. Simultaneity, GIS technology and the geo-spatial data have been used widely in electronic government affair, environmental protection, disaster control, ITS and etc. The users have realized the benefits more and more widely. Internet is an efficient way to distribute the geo-information, the State Bureau of Surveying and Mapping has give great effort to settle down the rules and standards to establish the clearing house. Some National Geo-standards have issued, and some of them are on the way. The GIS software is another important factor in the GIS industry. Chinese government working-out some good policy to supports the GIS software developer to have their own copyright. This paper is based on the above to introduce the status and development of Geomatics in China. in China.

At the design stage, it is very important to know the ship maneuvering characteristics from the view point of ship performance and for the safety of navigation. IMO only gives some criteria for ships in full load even keel condition. However, the ship generally is operated not only in full load condition but also in half load condition or ballast condition. Therefore we must estimate the ship maneuvering in different loading condition to ensure that the ship will satisfy with IMO rules and navigate safely in every condition. In this paper, we have investigated the maneuvering characteristics of a ship by simulation and experiments with real ship. By comparing with the results of simulation, the real ship tests conform with simulation test and previous researches. Therefore, the method base on real data is well done to estimate the ship maneuvering in different loading conditions. The change of ship's manoeuverability accoriding to ship's operation conditions was estimated.

There are various researches which proposed an automatic instance generation from freetext on the web. Existing researches that focused on English, adopts pattern representation which is generated by simple rules and regular expression. These simple patterns achieves high performance, but it is not suitable in Korean due to differences of characteristics between Korean and English. Thus, this paper proposes a novel method for generating patterns and instances which focuses on Korean. A proposed method generates high quality patterns by taking advantages of dependency relations in a target sentences. In addition, a proposed method overcome restrictions from high degree of freedom of word order in Korean by utilizing postposition and it identifies a subject and an object more reliably. In experiment results, a proposed method shows higher precision than baseline and it is implies that proposed approache is suitable for self-knowledge learning system.

Guillaume Apolinaire and Filippo Marinetti who are pioneers of the early 20 century in point of breaking traditional typographic rules and making particular typographic communication styles,have considered as the same categorytypoillustration or pictorial typography-in other studies evenif they have' particular differences. Their chromcal and theoretical background, works, exPressive materials and methods and the values were analyzed through thesis, books, periodicals and internet materials, and researched the characteristics. There are clear differences in the view of arranging type; expressive materials, sentence struction, layout. The most important differences are concrete expression by Apolinaire and abstract expression by Marinetti . These differences and characteristics made the base of Dada typography and the concrete typogaphers as Bradbury Thompson and Herb Lubalin were influenced by Apolinaire, abstract typographers as Piet Zwart and Neville Brody were influenced by Marinetti.
