  • Semantic Web programming is such an immature area that it is yet based on API calls, and does not provide high productivity in compiler time and sufficient efficiency in runtime. To get over this limitation, some efforts have been devoted on dedicated programming languages for Semantic Web. In this paper, we introduce a sophisticated cashing technique to enhance the runtime efficiency of RDF (Resource Description Framework) processing programs with SPARQL queries. We use static program analysis on those programs to determine what to be cashed, so as to decrease the cash miss ratio. Our method is implemented on programs in 'Jey' language, which is one of the programming languages devised for RDF data processing.

  • Since RDF (Resource Description Framework) triples are modeled as graph, we cannot directly adopt existing solutions in relational databases and XML technology. In order to store, index, and query Linked Data more efficiently, we propose a convergence indexing method combined R*-tree and K-dimensional trees. This method uses a hybrid storage system based on HDD (Hard Disk Drive) and SSD (Solid State Drive) devices, and a separated filter and refinement index structure to filter unnecessary data and further refine the immediate result. We perform performance comparisons based on three standard join retrieval algorithms. The experimental results demonstrate that our method has achieved remarkable performance compared to other existing methods such as Quad and Darq.

  • This study was conducted as a part of the project developing the standards of national board test for the dietitian's licence. The purpose of this study was to define the job description of dietitians, and to describe the task elements based on the detailed analysis of the dietitians' work. This study team established the research team which was composed of food and nutrition experts, 7 of registered dietitians and 3 of university professors. Draft job description form was made to fully explain the dietitians' task elements, process and sequence by the research team. Final job description form was confirmed after the validity of 576 task elements was reevaluated upon 4 point scale test based on the frequency, importance, and difficulty by 21 field registered dietitian by the study team. It was also confirmed by the university. This form was formated by following DACUM method which analyzed the job description containing duty, task and task elements. It was organized to include every dietitians' work and to describe the every detailed process of work. Duty was defined as the specific and independent work as a dietitian, and was composed of 17 parts, i.e 10 parts in food supply management area and 6 parts in nutritional care service area and self promotion area. Duties were also divided into 99 tasks containing the 576 detailed task elements to describe definite action, steps and decisions. Seventeen parts are following; menu planning, storage and inventory control, food production, meal service, waste management, sanitation, equipment and facility management, human resource management, financial management, nutrition assessment of life cycle, nutritional assessment of several disease, nutritional assessment in specific condition, medical nutrition therapy, nutritional education, public health nutrition and self promotion. If these protocols are properly performed and presented, they can provide the likelihood that dietetics professionals work as a primary contributors in promoting health care and preventing disease nationally.

  • Purpose: The aim of this study was to analyze the needs of HIV/AIDS care and to develop the job description of HIV/AIDS Counselling nurse in Korea. Methods: The needs assessment was done by focus group interview with HIV/AIDS care recipients who are 16 persons living with HIV/AIDS and four their family members, seven persons from HIV/AIDS high risk group, and five nurses working on HIV/AIDS clinics. Based on the result of needs assessment, job description was developed using the DACUM. Mail survey was done to identify the frequency, importance, and difficulty of duties, tasks, and task elements. Results: The job description was classified under 8 duties, 36 tasks, and 290 task elements. Duties were categorized as needs assessment, health promotion and quality of life, improvement of treatment compliance, symptom care, health education, resource network, administrative activity, and career development. The importance of all duties and tasks showed high score from the survey, but the frequency and the performance level were middle range. Conclusion: It is suggested that the special training program based on the job description needs to be developed. In the political aspects, the introduction of HIV/AIDS nurse specialist certification could be considered.

  • This study was to suggest the new rules for revision of KCR4 by comparing between ISBD consolidated edition and KCR4. The study methods was to compare the rules in each element after mapping the description elements in each area of ISBD and KCR4. Resultingly, first, content forms and media types must be included for describing resource types. Second, it is needed for rules about the common title and the dependent title. Third, it is needed for rules about "parallel" such as parallel title, parallel other title information, parallel statement of responsibility relating to title, parallel edition statement, parallel statement of responsibility relating to edition, parallel numbering system, parallel place of publication, production and distribution, et. al. Fourth, the rules about material or type of resource specific area must be regulated in terms of the contents of the resource. Fifth, the home country principle must be not applied in describing the place of publication, production and distribution for the consistency. Sixth, it is needed to regulate the extent, other physical details, dimensions, and accompanying material statement for all materials instead of the material description according to material types. Seventh, rule number of notes must be agreed to number of main rules. Eighth, it is needed for detailed rules about resource identifier. This study might be contributed to revise the KCR4.

  • Video adaptation in response to dynamic resource conditions and user preferences is required as a key technology to enable universal multimedia access (UMA) through heterogeneous networks by a multitude of devices in a seamless way. Although many adaptation techniques exist, selections of appropriate adaptations among multiple choices are often ad hoc. To provide a systematic solution, we present a general conceptual framework to model video entity, adaptation, resource, utility, and relations among them. It allows for formulation of various adaptation problems as resource-constrained utility maximization. We apply the framework to a practical case of dynamic bit rate adaptation. Furthermore, we present a description tool, which has been accepted as a part of the MPEG-21 Digital Item Adaptation (DIA), along with a brief overview of the .elated descriptors to support terminal and network quality of service (QoS).

  • The information space of semantic web comprised of various resources, properties, and relationships is more complex than that of WWW comprised of just documents and hyperlinks. Therefore, ranking methods in the semantic web should be modified to reflect the complexity of the information space. In this paper we propose a method of ranking query results from RDF(Resource Description Framework) knowledge bases. The ranking criterion is the importance of a resource computed based on the link structure of the RDF graph. Our method is expected to solve a few problems in the prior research including the Tightly-Knit Community Effect. We illustrate our methods using examples and discuss directions for future research.
