Purpose: This study aimed to develop a nursing handoff protocol for intensive care units and test its relevance. Methods: This is a methodological research to develop a protocol. A preliminary protocol was developed by composing items and testing content validity through literature review and experts' review. We revised and complemented the preliminary protocol following practical relevance assessment of 38 intensive care unit nurses at a university hospital to test content validity and to assess practical relevance of the final protocol. Results: On the basis of the content validity test for the final protocol, 40 items were adopted. The scores for the practical relevance of the final protocol increased significantly for items such as accuracy of handoff, reduction of handoff-related errors, convenience in using the protocol, reduction in handoff time, and simplification of handoff. Conclusions: The nursing handoff protocol for intensive care units in this study is expected to improve nursing performance with a standardized handoff in intensive care units, promote patient safety, and improve communication among the medical staff.

A new emotion-based image retrieval method is proposed in this paper. Query emotion descriptors called query color code and query gray code are designed based on the human evaluation on 13 emotions('like', 'beautiful', 'natural', 'dynamic', 'warm', 'gay', 'cheerful', 'unstable', 'light' 'strong', 'gaudy' 'hard', 'heavy') when 30 random patterns with different color, intensity, and dot sizes are presented. For emotion image retrieval, once a query emotion is selected, associated query color code and query gray code are selected. Next, DB color code and DB gray code that capture color and, intensify and dot size are extracted in each database image and a matching process between two color codes and between two gray codes are peformed to retrieve relevant emotion images. Also, a new relevance feedback method is proposed. The method incorporates human intention in the retrieval process by dynamically updating weights of the query and DB color codes and weights of an intra query color code. For the experiments over 450 images, the number of positive images was higher than that of negative images at the initial query and increased according to the relevance feedback.

In order to minimize a biased view of evaluators in usability test, a multiple evaluation method so called Multi-Centered Usability Evaluation Method(MCUEM) was suggested and structured in this study. To use MCUEM, the existing evaluation methods were re-categorized into 'developer and evaluator-centered', 'evaluator-centered', 'user-centered', 'evaluator and user-centered', and the 'developer, evaluator, and user-centered methods. Furthermore, in order to verify the relevance of MCUEM, the usability of mobile phone was tested in this study. In results, it was found that different evaluation methods generated greatly different results, that showed the risk of using a particular usability method due to different perspectives of evaluators. At the same time, it was found that MCUEM could greatly minimize such biases. Therefore, it was concluded that using MCUEM could help the usability engineer design a test protocol with a minimal risk of bias due to different perspective of evaluators.

Modern education, with special reference to higher education (HE), is far taken out of the traditional meaning of education. A number of business features have infiltrated these institutions of HE where students assume the place of a customer. In the present business scenario customer relationship management (CRM) technology assumes an important role in managing customers. Therefore a relevant question would be to know whether educational institutions need to implement this technology to manage their constituent relationships. This paper makes an attempt to evaluate studies on commercial features of a modern educational system and then present the findings of a study conducted to know the relevance of CRM Technology in HE. An evaluation is also made to know the awareness of the concept of CRM among the educators. The findings show that the educators' awareness of CRM strategies is good, of CRM concepts is poor and of practice is average. Further, an overwhelming majority of the respondents felt that CRM is relevant for educational institutions in the present scenario.

At present, 3 names about undersea features in the East Sea - Korean Plateau, Tsushima Basin, Syun-yo Bank - are listed on Gazetteer Any explanations are not given for registration of these names. Just it seems that the names written on International marine chart(INT 511) were recorded to Gazetteer. Furthermore Tsushima Basin and Syun-yo Bank have no oceanographic, geologic reason and geographical relevance, and the names should be replaced by Ulleung Basin and Isabu Tablemount, respectively, that is deeply related to geographical relevance and genetic origin.

Urdu is a widely spoken language in the Indian subcontinent with over 300 million speakers worldwide. However, linguistic advancements in Urdu are rare compared to those in other European and Asian languages. Therefore, by following Text Retrieval Conference standards, we attempted to construct an extensive text collection of 85 304 documents from diverse categories covering over 52 topics with relevance judgment sets at 100 pool depth. We also present several applications to demonstrate the effectiveness of our collection. Although this collection is primarily intended for text retrieval, it can also be used for named entity recognition, text summarization, and other linguistic applications with suitable modifications. Ours is the most extensive existing collection for the Urdu language, and it will be freely available for future research and academic education.

The Meta Search system proposed in this paper is operated based on relevance distribution Infer mation(RDI). It first evaluates the sources applicable to the search, and then selects the most appropriate source. According to the evaluation of the sources, it discreetly collects the documents from the concerned sources and classifies them into a useful order based on the RDI, which is an evaluation score of the sources. The documents are classified into order and presented to the user as a single search result. For this Purpose, this study presents evaluation factor models to present the RDI between the query, and source, and proposes a method for drawing out the RDI based on the evaluation factors. The system for selecting the most appropriate sources according to the query has been developed based on an algorithm that selects the best source. Finally, after searching the documents suitable for query from extracted sources, we present a Meta Search system, HoleInOne, that ranks and merges them.
