The railway signaling system consists of computerized vital devices. Therefor it is important to validate the required functions of developed signaling system. To verify the condition and functions of signaling functions, the plentiful laboratory test is required. To achieve this, the emulation S/W for signaling test-bench is needed. The object-oriented concept for trackside signaling equipments emulation is described in this paper.

최근 홈페이지 기반의 다양한 기능이 개발, 적용되고 있어 웹사이트 재구축시 기능 개선 등의 이유보다는 디자인 재구성을 통한 인터페이스 개선을 꼽는 경우가 대다수로 나타나고 있다. 본 논문은 디자인 변경을 위해 기능 전체를 재개발하는 것이 아니라 개발된 템플릿을 활용하여 인터페이스를 변경하는 방법을 제안하고자 한다. 이 방법은 웹사이트 재구축시 개발 기간의 단축, 비용의 절감, 필요 인력의 최소화 등의 이점을 얻을 수 있다.

Aqueous cleaning agents which are considered to be environmental-friendly and promising alternative ones among various industrial cleaning agents were evaluated in this words. In order to formulate aqueous cleaning agents, primary alcohol ethoxylates with 3, 5 and 7 moles of ethylene oxides among nonionic surfactants were selected as main surfactants. And anionic surfactants and alcohols were chosen as their cosurfactants. Builders such as NaOH, KOH, $Na_2CO_3$ and $NaHCO_3$ were also evaluated as additives for improvement of cleaning efficiency of aqueous cleaning agents. The experimental results of cleaning ability tests show that introduction of anionic surfactant TLS as cosurfactant in alcohol ethoxylate-based aqueous solution gives the best cleaning efficiency for removing mixed soil of cutting oil and grease. NaOH and $Na_2CO_3$ are also shown to play an important role for improvement of cleaning efficiency in a aqueous cleaning agent.

This study has developed a mobile AR contents Builder (MARB) featuring the augmentation of virtual objects, e. g. 2D images, 3D models and videos on user-preferred markers in mobile environment and with connected interaction events. The developed MARB is capable of augmenting multiple virtual objects on markers preferred by users, and selectively supporting many marker-specific interaction events. The MARB is also developed as a mobile App for convenience of use in the mobile environment. This makes users to implement AR contents by a GUI-based authoring procedure on the mobile device. The developed MARB allows App developers and general users to author mobile contents easily and can be applied to various field by those who wish to use diverse mobile AR contents. Moreover, the MARB will provide solutions for the expansion of mobile AR market, by overcoming the difficulties of mobile AR content development.

A contract for the shipbuilding is usually a complicated and involves statement of rights, obligations and responsibilities which each party agrees vis-a vis the other. The ultimate purpose of the contract is the sale and transfer of the finished ship by the builder to the buyer. Contracts for the construction and sale of ships are categorized as contracts for the sale of goods under English, United States, Germany and some countries law. On the other hand, The shipbuilding contract may be classified, not as a contract of sale but as a contract for work and materials under Korea, Japan and some countries law. Especially, most of countries are now well settled with regard to liability of a manufacturer in tort for physical injury and on the other for pure economic loss to remote owners of chattels. Where there is either a breach of contractual warranty or an implied warranty, there may be admiralty jurisdiction, depending once again on the situs of the event and its relationship to traditional maritime activity. Contract principles will be applied to the first type of warranty and tort principles will be applied to the second. First of all, this thesis is dealt with the contents of contract under English Law. Secondly, this thesis is analysed into the liability of shipbuilder in Products Liability under English, American and Korean Law comparisons. In conclusion, the author tries to give some suggestions as countermeasures of Products Liability to the shipbuilder in Korea.

The Web is evolving toward the Semantic Web. Ontologies are considered as a crucial component of the Semantic Web since it is the backbone of knowledge representation for this Web. However, most of these ontologies are still built manually. Manual building of an ontology is time-consuming activity which requires many resources. Consequently, the need for automatic ontology extraction tools has been increased for the last decade, and many tools have been developed for this purpose. Yet, there is no comprehensive framework for evaluating such tools. In this paper, we proposed a set of criteria for evaluating ontology extraction tools and carried out an experiment on four popular ontology extraction tools (i.e., OntoLT, Text-To-Onto, TERMINAE, and OntoBuilder) using our proposed evaluation framework. The proposed framework can be applied as a useful benchmark when developers want to develop ontology extraction tools.

Up until now, when a user search product information, the keyword-based search that mainly uses frequency of words or vocabulary information has been utilized in large. In the keyword-based research, the user should have to bear additional burden in order to search the displayed results manually once again because it shows those files that have no connection at all with the inquiries made by the user. To resolve such a problem, ontology has been emerged. In this paper, product search system using ontology was constructed directly and also tested how accurate search it does perform through the searching according to classification. To test this, about 40,000 product data of A discount store, which was operating on/off line discount stores, were constructed as database, and developmental environment for User Interface was tested by having developed the search system using JSP and PowerBuilder 9.0. Results from the test proved that the search method using Domain Ontology for product presented and designed in this paper was superior to the existing keyword-based search method.
