Library of Congress introduced BIBFRAME as a new bibliographic framework to enhance web accessibility of bibliographic records and their integration to Web of data. This study introduces BIBFRAME model and its current status, reviews BIBFRAME classes and properties, and presents a mapping between MARC21 and BIBFRAME. The study aims to help the understanding the deployment of BIBFRAME in bibliographic description. BIBFRAME categorizes bibliographic entities into Work-Instance, and employs RDF/XML and URIs to identify resources and specify semantics of the resources on the Web. It also suggests an Annotation entity to provide additional information produced by users and external organizations. BIBFRAME is significant in that it presents a new paradigm of bibliographic description and expands users' information discovery in the context of Linked Data. Continuous researches are required to support its content model agnostic application to diverse resource type, which may entail a modification of BIBFRAME model and vocabulary. It also calls for guidelines for using the complicated vocabulary in a coherent way.

The goal of this study was to investigate how hypotheses were elaborated after their initial appearances in the context of scientific problem solving. Data were collected from a class in which preservice elementary school teachers in groups carried out abductive inquiry of earth science. The analysis revealed two major processes of hypothesis elaboration: theory-driven and evidence-driven. The theory-driven process was in turn distinguished into two kinds of subprocesses: one is in pursuit of internal coherence and the other external coherence. The evidencedriven elaboration also had two subprocesses, which were triggered by direct evidence and indirect or analogical evidence, respectively. In addition, hypotheses were more often than not modified by a wrong theory or evidence whether it was driven by a theory or evidence. Implications for science education and related research were discussed.

This study aimed to reveal that a local city was recreated by tourism, and to discover a general process in which the regional identity as a tourist destination was reconstructed. Specifically, firstly, this study suggested that the social construction of cultural tourist destinations was composed of a series of dynamic stages such as 'reinterpretation', 'institutionalization', and 'recognition' conceptually. Secondly, the dynamic stages were analyzed on the ethnographic study of Otaru where the movement of preservation of the historical canal was raised and strategies to attract tourism had been implemented. Thirdly, a main mechanism acting on each stage was examined. In conclusion, it was shown that the region was reinterpreted through the politics of identity and the meaning was institutionalized through political and economic negotiation. Moreover, while being established as a constructed authenticity by politics of memory, the regional identity was embedded in the socio-spatial consciousness constantly.

It was found that Korean Standard of Estimate which has been used as the only basis of cost estimate of public construction projects had some side effects such as jerry-build construction and over-estimation because it failed to reflect the current price and the state-of-the-art construction methods in a changing construction environment. Therefore, the government decided to gradually introduce historical construction cost into cost estimate of public construction projects from 2004. This paper presents analytic criteria and a process model for deducing more current and reasonable historical construction cost for contract items from not only previous contract prices but also all of the other bid prices that were not contracted. The procedure of estimating actual unit cost proposed in this paper focuses on the removal of abnormal values including strategically too low or high prices and the time correction. In addition, basic research is conducted for the correction of actual unit cost through the analysis of fluctuation of bid price depending on bidding types and rates of successful bid. It is anticipated that the effective use of the proposed process model for estimating actual unit cost would make the cost estimation more current and reasonable.

Robots have been recognized as effective tools to promote high level thinking such as creativeness and problem solving that are crucial in Intelligence & Information era. However, robot education in Korea is more concerned with assembling, traveling and programing, while robot education in foreign countries are incorporated with educational courses, being utilized in various ways. Essentially, robot is a multifunctioning device of planning, assembling, operation and problem solving. As it is able to provide practical educational experience, it will positively influence in motivation and accomplishment if being incorporated with educational courses. Therefore, this study compared domestic and foreign robot education cases, while establishing the framework of course incorporated robot education based on analysis of robot mechanism, the 7th curriculum and its activities. We developed robot utilizing educational program by each grade and subject. In addition, this program is reviewed by experts to verify its adequateness, reality and usefulness based on which it was revised and supplemented.

Computer education currently executed at middle schools showed problems of system of education curriculum, repetition, and lack of consistent system as a result of analyzing index for information and communication technology curriculum, and related literatures, and most of the education contents have difficulty to nurture logic thinking and problem-solving ability since they are composed mainly of software function learning. Concerning this issue, this study suggests an innovated computer education curriculum with reinforced information ethics field with computer principle, algorithm, and programming, in other words, a corrected and supplemented version of former content system based on computer science guidance cases of ACM computer science curriculum model of USA, computer science curriculum of Florida state, and Unplugged Project(http://www.unplugged.canterbury.ac.nz) judging that introduction of computer science factors are desperate to improve computer education curriculum in middle schools.

In case of unit testing, White-box test can be used to closely check source code and to analyze logic and statement errors. On the other hand, in case of function testing of system level, Black-box test can be mainly used to compare actual and expected results by inputting test data because the scale of function is large. This Black-Box test in system testing level has problem in tracing errors in source code when we find errors. Moreover applying White-box test is not easy for system testing level because the levels of test target are different. Therefore this paper suggests the vertical test method of a practical and integrated system level which can checks up to source code level using White-box test style although it aims to test the highly abstract level like a system function. In addition, the experiment explains how to apply the vertical test by displaying an example which traces from UML specification model to the source code and also shows efficiency of error trace.
