Objective: The aim for this article was to evaluate and to clarify the current opinions of the registered pharmacists concerning their recognition and adoption rates about introducing the preceptorship into the clinical pharmacy internship and clerkship. Methods: A 25-question-questionnaire was developed and pilot tested. For 40 days of survey by both on-line and on site, 90 over 240 (37.5%) registered pharmacists responded and the data were analyzed with comparison to the groups working in community and hospital pharmacies. Results: The overall answers were affirmative and the respondents were very interested in the application of the clinical preceptorship to the pharmacy educational and to their clinical settings. Moreover, the qualification level and the implementation methods were proposed in detail. Conclusion: Although ninety pharmacists showed their views differently, most of the respondents regarded the preceptorship as an adequate training system for the pharmacy students as well as junior pharmacists at the time of initiation of the new 6-year pharmacy education system in Korea.

Because a quantity wireless internet contents is much less than wired internet contents, it exist high necessities that wired internet contents should be converted into wireless internet contents. The conversion server implemented in this paper, automatically recognizes the type of user agents when they request, retrieves source documents on the web site specified by an URL, generates metaXML documents as an intermediate form, and converts them wireless markup documents appropriate for user agents. The conversion server interoperates with the image converter for image conversion and the clipper which is an authoring tool for clipping existing wired internet documents. We performed experiments about capability of the conversion server transcoding static/dynamic web pages specified by an URL. According to performance results on dynamic web pages, the conversion server showed better throughput when a thread pool in the terror maintains 5 threads compared with 1 and 10 threads.

Delay in the process of Information Extraction, IE, is largely due to inability to correctly recognize the user's information requirement of particular search factors. Especially if the wrapper rules are used in a search engine, the search generally fails to classify internet documents properly and efficiently since the application of the same wrapper rules lacks extensibility throughout various types of existing internet document. In case of buying or selling a ship, if the price range, type. place of delivery, inspection site and other information relevant to the sales would be available through the internet for proper retrieval the sales could more readily succeed by using Ontology relating to sales or purchase information and by selectively searching for the desired information through the content based retrieval system. This system proposes to improve various wrapper systems existing throughout different internet sites and to eliminate unnecessary information tagged on the existing internet documents in order to create a more advanced information retrieval system.

This paper proposes a design and realization for the semantic search system. The proposed model includes three Architecture Layers of a Semantic Search System ; (they are conceptually named as) the Knowledge Acquisition, the Knowledge Representation and the Knowledge Utilization. Each of these three Layers are designed to interactively work together, so as to maximize the users' information needs. The Knowledge Acquisition Layer includes index and storage of Semantic Metadata from various source of web contents(eg : text, image, multimedia and so on). The Knowledge Representation Layer includes the ontology schema and instance, through the process of semantic search by ontology based query expansion. Finally, the Knowledge Utilization Layer includes the users to search query intuitively, and get its results without the users'knowledge of semantic web language or ontology. So far as the design and the realization of the semantic search site is concerned, the proposedsemantic search system will offer useful implications to the researchers and practitioners so as to improve the research level to the commercial use.

Sharing cross-site resources has been adopted by many recent websites in the forms of service-mashup and social network services. In this change, exploitation of the new vulnerabilities increases, which includes inserting malicious codes into the interaction points between clients and services instead of attacking the websites directly. In this paper, we present a system model to identify malicious script codes in the web contents by means of a remote verification while the web contents downloaded from multiple trusted origins are executed in a client's browser space. Our system classifies verification items according to the origin of request based on the information on the service code implementation and stores the verification results into three databases composed of white, gray, and black lists. Through the experimental evaluations, we have confirmed that our system provides clients with increased security by effectively detecting malicious scripts in the mashup web environment.

The safety and health ledger system, which gives the responsibility of safety and health management for construction site workers to the construction project owner, was introduced as part of the overall revision of the Occupational Safety and Health Act. There is a need to explain the system's effectiveness in terms of economic feasibility to solve the execution problem of the system caused by low awareness and implementation rate. In this study, the economic effect of implementing the safety and health ledger system was analyzed using cost-benefit analysis based on the data discussed at the time of the introduction of the system. Results show that creating and managing the design safety and health ledger caused additional costs in implementing the system. As a result of comparing the cost of preparation and the direct and indirect benefits caused by the reduction of industrial accidents, the benefits were evaluated higher than the costs. Thus, it is thought that the safety and health ledger system reduces construction work accidents and generates economic effects.

In this paper, we propose a mobile remicon quality management system to enable inspection and correspondence with a smart phone in the field check of remicon. We also proposed a real-time slump data processing part to digitize field inspection and XML formats for data exchange with the server. We used the smart phone to transmit real-time image about field inspection of remicon and judged the error at the same time. By doing this, we shared the situation of the remicon products in the field and the head office. Based on the actual results, the development technology is used to determine whether the product is abnormal or not, and to provide appropriate information to the company and the site. Based on the analysis of raw material quality data, it is possible to present real time optimal blending ratio according to raw material import with raw material management data, which is the biggest problem of the ready mixed concrete industry.
