  • This study examined the content diversity of seven authorized science textbooks by comparing the characteristics of the science concept description and the contents of inquiry activities in the "weight of objects" unit. For each textbook, the flow of concept description content and the uniqueness of the concept description process were analyzed, and the number of nodes and links and words with high connections were determined using language network analysis. In addition, for the inquiry activities described in each textbook, the inquiry subject, inquiry type, science process skill, and uniqueness were investigated. Results showed that the authorized textbooks displayed no more diversity than expected in their scientific concept description method or their inquiry activity composition. The learning elements, inclusion of subconcepts, and central words were similar for each textbook. The comparison of inquiry activities showed similarities in their contents, inquiry types, and scientific process skills. Specifically, these textbooks did not introduce any research topics or experimental methods that were absent in previous textbooks. However, despite the fact that the authorized textbook system was developed based on the same curriculum, some efforts were made to make use of its strengths. Since the sequence of subconcepts to explain the core contents differed across textbooks, this explanation process was divided into several types, and although the contents of inquiry activities were the same, the materials for inquiry activities were shown differently for each textbook to improve and overcome the difficulties in the existing experiments. These findings necessitate the continuation of efforts to utilize the strengths of certified textbooks.

  • Purpose: The purpose of this study was to identify trends of nursing concept development in Korean journal papers to improve accurate understanding of nursing concepts. Methods: A systematic review of 216 concept development articles published from 1970 to 2018 that met the inclusion criteria was conducted using Research Information Sharing Service (RISS) databases. Results: The most common method of concept development was Walker and Avant's concept analysis method, identified in 139 (64.3%) of the 216 studies, followed by 48 examples of hybrid models (22.2%) and 15 examples of evolutionary methods (6.9%). Chinn and Kramer's method, Norris's clarification, Wilson's method, and others were also used. The concepts of "spirituality" and "fatigue" were most frequently analyzed. Among the 139 studies that used Walker and Avant's concept analysis method, 127 studies (91.4%) applied all the recommended steps; the others applied the recommended steps partially, omitting description of model cases/additional cases, antecedents/consequences, and empirical indicators. Among the studies using the hybrid model, among two (5.7%) did not describe attributes, three (8.5%) did not provide definitions, and 16 (45.7%) did not present empirical indicators in the final stage. Conclusion: Among concept development studies published in Korean journals, Walker and Avant's concept analysis method is most commonly used. In case of most studies using Walker and Avant's method a suitable concept analysis process is applied, but in case of other studies using the other concept development method, a suitable concept analysis process is not applied. Therefore, a suitable concept analysis process must be applied for concept development in nursing research.

  • Purpose: This research is a descriptive study to explore "patient respect" in nursing. Respect was analyzed as a concept in the domain of the patient. The Hybrid Model suggested by Schwartz-Barcott and Kim was used in this study. Method: For the theoretical phase, nursing and other literature were reviewed to analyze attributes and develop a working definition of the concept, respect. For the fieldwork phase, four subjects in two general hospitals in Seoul participated. With the participants' permission, the data was collected between January and April, 2002, through in-depth interview and participant observation. The data analysis progressed at the same time as the fieldwork. Data analysis proceeded according to the analysis method of Strauss and Corbin. Result: The final attributes of patient respect are suggested by consideration, recognition, cordial treatment, concern, honesty, acceptance. The final definition of patient respect as a concept in the domain the of patient is suggested by "Patient respect is that the patient is recognized as an individual with worth and is accepted, and considered to be that kind of an individual person. In addition, the patient is recognized to be an independent person and is treated with concern and honesty." Conclusion: The results of the analyses is helpful in integrating into a comprehensive description of the concept, Patient Respect.

  • A Semantic Web based service description is to enable intelligent matchmaking of services by improving representational flexibility and expressiveness in service description for Web Services. Flexibility concerns the way of how a computer handles the discrepancies in the granularity and the structure of service description between different participants of web services. Expressiveness means richness in the semantic description of services (or ontological representation of each service as a concept). The main shortcoming of currently available industry standard framework for e-commerce such as UDDI and ebXML is that they do not allow much flexibility and expressiveness in the service description. In our research we analyze the requirements of extending service description based on the Semantic Web, especially in the context of DAML-S. We also propose a method to be applied to implement intelligent web services by implementing a virtual auction site, testAuction.com. Finally, we consider some theoretical issues regarding the framework for web services using ontology.

  • The discrete crack-concept is applied to study the 3D propagation of tensile-dominated failure in plain concrete. To this end the Partition of Unity Finite Element Method (PUFEM) is utilized and the strong discontinuity approach is followed. A consistent linearized implementation of the PUFEM is combined with a predictor-corrector algorithm to track the crack path, which leads to a robust numerical description of concrete cracking. The proposed concept is applied to study concrete failure during the PCT3D test and the predicted numerical results are compared to experimental data. The proposed numerical concept provides a clear interface for constitutive models and allows an investigation of their impact on concrete cracking under 3D conditions, which is of significant scientific interests to interpret results from 3D experiments.

  • Today the market of EDMS is esteemed more than 100 billions won. It signifies a comming of age of electronic records. The traditional archival theories which are based on the paper records are confronted with a new challenge. In some leading countries of archival studies reorientation of archives management has been tried by a number of distinguished specialists such as Bearman and Hedstrom since 10 years. As a consequence new paradigm of archival theories has been developed. Also in Korea this new paradigm has been introduced by some expert such as Lee, Sang-Min, Sul, Moon-won, Lee, Seung-Eok. However their arguments are too general to offer a concrete clue for new paradigm. Faced by new age of electronic records, it's important to start a discussion for the reasonable methods of electronic records management at once. The most drastically changed part of record management by the electronic technique is the life-cycle of records. The commonly practiced three-stage life-cycle is to be reduced to the two-stage life-cycle, and the concept of the spatial movement of records is to be changed. It can be also pointed that the public emerges as user from the early creating stage of records beyond time and space. Thus is can be said that the method of the management features dynamic and cohesive. The method of appraisal must be also changed and reproduced, so that it can reflect the various levels considering dynamics of the electronic records. Supposedly it will be a core factor that causes the change of methodology in records management with the change of life-cycle theory. It must be noted that various subjects would be involved in the work of classification and description over time and space and that feedback between them is of important. Description also tends to be made at the crating stage of records and structured dynamically. It results from the change of life-cycle and the introduction of the concept of continuum. Such trend allows us to start discussions on the assumption that description of both creator and archival professionals act together an important role. Of course, it is linked with the methodology in which most descriptions are made automatically at the early drafting stage of the structure. The meat date is formed on the assumption that there should be feedback between areas of automatic description, description of creators and archival professionals. The most important thing in description is to develop a suitable way how it is structured. An alternative must be offered for managing data set. As iweb that is being operated by Myongji university shows, records created in daily business are managed not as electronic records but as date base. This is because they exist outside the repository in the EDMS system. Since data set often has various sources, an alternative for classification needs to be developed. It is now likely that database is filed according to the created year to be transferred automatically to the repository. Over a long-term the total management of database, electronic records and electronic information will be a topic. A right direction of new paradigm will be found for both iweb and E-government, when practice and studies of theories are combined and interacted.

  • Currently be proceeded a lot of researchers for 'user information demand description' for interface of an information retrieval system or Web search engines, but user information demand description for a natural language form is a difficult situation. These reasons are as they cannot provide the semantic similarity that an information retrieval model can be completely satisfied with variety regarding an information demand expression and semantic relevance for user information description. Therefore, this study using the description logic that is a knowledge representation base of OWL and a vector model-based weight between concept, and to be able to satisfy variety regarding an information demand expression and semantic relevance proposes a decision way for perfect assistances of user information demand description. The experiment results by proposed method, semantic similarity of a polyseme and a synonym showed with excellent performance in decision.

  • The purpose of this study is to identify the problems of describing bibliographic elements such as edition, impression, and year of publication in the current Cataloging Rules, and to present improvements to the KCR and the KORMARC Format. According to changes in the information technology environment in the library, the level and scope of the cataloging that can be provided to users should be adjusted. As data is diversified and descriptive method of metadata develops, the development of bibliographic elements and the change of the descriptive method are changing the framework of the existing standardization. As a research method, we will examine the concept of edition and impression, examine the transition process of description of edition and impression targeting KCR. And we would like to present the methods of bibliographic description to be added or modified through cataloging examples, and examine the format reflected in KORMARC. This study is intended to be limited to the descriptive form of books. The bibliographic elements of the entry in the library must be fully consistent with the bibliographic elements of the material to be catalogued. This study suggests an improvement to the cataloging rules. First, the edition of the cataloging rules shall describe the edition statement and the impression statement. In addition, the description of the year of publication describes the latest year, not the first year of publication of the edition of the material to be catalogued. The descriptive scope of the year of publication is extended to the month of publication. Second, in the KORMARC format, the description of impression in edition statement is given to the identifier in the 250 field, and is numerically described as the second impression. When presenting the month and year of publication, one identifier in the field 260 describes the year of publication and the other identifier describes the month of publication. The description for the month and year of publication is stated the latest month and year on the title page and the colophon of the publication.

  • In order to construct the extrusion die surface of arbitrarily shaped sections, an automatic surface construction method based on NURBS surface and area mapping method is proposed in the present work. In the present study, a center point for area mapping is determined by introducing the marring concept based on constant area proportionality between original billet and final product. The characteristic points of inlet profile is determined using the traditional area mapping method and the root finding numerical method. The inlet and outlet profiles are precisely described with NURBS curves using the characteristic points of entry and exit sections. For the construction of NURBS surface, an interpolation method for the pre-determined two section curves has been developed to be used in the generation of interior control points and weights. To show the validity of the proposed method, automatic die surface generation is carried out for the several kinds of shaped sections.
