YouTube videos of public institutions are digital public records that need to be managed and preserved. As such, the video and the metadata describing the video should also be preserved. This study aims to select the key metadata elements necessary for archiving videos published on YouTube by public institutions. To this end, five high-level areas, namely the description, structure, management, preservation, and user participation, and the metadata elements of 10 subareas, were designed by referring to NAK 8, PREMIS, ISAD(G), and YouTube metadata. Afterward, the metadata elements designed by 14 experts were verified. Lastly, the validity and reliability of the evaluation results were verified. Of the 63 elements, 33 satisfied the validity and reliability criteria. Thus, these elements were selected as the core metadata for archiving YouTube videos in public institutions.

In the present paper, a novel systematic method using the 2-D hybrid special finite elements containing an edge crack is employed to study the fracture behaviors of laser beam spot-welds in automotive structures. 2-D hybrid special finite elements each containing an edge crack can assure the high precision especially in the vicinity of crack tips and give a better description of its singularity with only one hybrid element surrounding one crack. Therefore, the numerical modeling of the laser beam spot-welds can be greatly simplified. Some numerical examples are provided to demonstrate the validity and versatility of the proposed method. All the lap-shear, lap-tension and angle clip specimens are analyzed and some useful fracture parameters (such as stress intensity factors, the initial direction of crack growth) are obtained simultaneously.

The present paper concerns the macroscopic overall description of rheologic properties for steel wire and synthetic fibre cables under variable loading actions according to non-linear creep and/or relaxation theory. The general constitutive equations of non-linear creep and/or relaxation of tension elements - cables under one-step and the variable stress or strain inputs using the product and two types of additive approximations of the kernel functions are presented in the paper. The derived non-linear constitutive equations describe a non-linear rheologic behaviour of the cables for a variable stress or strain history using the kernel functions determined only by one-step - constant creep or relaxation tests. The developed constitutive equations enable to simulate and to predict in a general way non-linear rheologic behaviour of the cables under an arbitrary loading or straining history. The derived constitutive equations can be used for the various tension structural elements with the non-linear rheologic properties under uniaxial variable stressing or straining.

In this work a numerical study to find the characteristics of the internal flow and mixing process has been conducted in a static mixer used in the system of catalytic combustor of the fuel cell power plant. After introducing the model description and final governing equations the present numerical approach is applied to the analysis of static mixer, which may have one or more helical elements inside the circular tube by changing such various parameters as incoming mass flow rates and the number of helical elements. The results show that although the static mixer is efficient in mixing fuel and air, more optimization processes are required to achieve the appropriate mixing characteristics in front of the honeycomb type catalytic combustor used in the MCFC power plant

Many picture books are published every year. Book reviews can play an important role in building knowledge about newly published book. This study analyzed data the coverage and content of reviews in journals with a view to helping librarians and parents become more aware of content and coverage of reviews for picture books. Variations of bibliographic and ordering information appeared among all journals. Most reviews typically included a plot summary and a general statement about the illustrations. Overall, journals provided more comments on literary elements than artistic elements. However, reviews provided insufficient information about the background of reviewers. Physical description of the books appeared in 8.81 % of the sample.

Caring is the essence and it is the central and unifying domain for the body of knowledge and practice in nursing. However a clear conceptualization of what caring in nursing does not yet exist. The purpose of this study is to research the phenomenon of caring by obtaining verbal description of the experience of caring in handicapped children, to provide basic information for developing theory of caring, and to teach the humanism centered education. The study design was a descriptive study using phenomenological method. The subjects for this study were 26 nursing students who cared for handicapped children in S rehabilitation center from August, 24 to October. 29 1994. Van kamm's phenomenological method was used for the analysis of the datas. The results are as follows : The experience of caring was classified with 15 common elements and 61 descriptive expressions from 120 raw data. The common elements were , , , , , , , , , , , , , .

Earthquake-induced pounding is one of the major reasons for structural failure in earthquake prone cities. An accurate description of the pounding phenomenon of two buildings requires the consideration of systems with a large number of degrees of freedom including adequate contact impact formulations. In this paper, firstly, a node to surface formulation for the realization of state-of-the-art pounding models for structural beam elements is presented. Secondly, a hierarchical substructure technique is introduced, which is adapted to the structural pounding problem. The numerical accuracy and efficiency of the method, especially for the contact forces, are verified on an academic example, applying four different impact elements. Error estimations are carried out and compared with the classical modal truncation method. It is demonstrated that the hierarchical substructure method is indeed able to significantly speed up the numeric integration procedure by preserving a required level of accuracy.

In order to overcome the problems of current approaches to metadata interoperability based on element mapping, this research proposed Master Element Framework that is an alternative approach to metadata interoperability. It is an approach to integrate metadata elements that have the same value, instead of direct mapping between similar elements. Master Element Framework is constructed to semantically integrate metadata elements in a hierarchical order and to interconnect between heterogeneous metadata standards. This approach is expected to be an alternative approach to metadata interoperability.
