Computer simulation endow a military man with field training such as combat experience without operating combat strength or capabilities. To samely construct simulation environment against actual combat environment is to well construct DB to operate war game model, associate among federates on network. we construct virtual combat environment enabling to efficiently manage network traffic among federates(or active nodes) on active network that construct virtual military training space such as urgent combat field needed to rapidly transfer combat information including image and video.

The purpose of current study is about how to construct wall-type APT in slip form and Deck plate applied different connection of materials that wall and slab. A proposal construct's solution is using the continuous a binding string that the main of contents are slab or stairs which horizon structure part construction is joined the vertical structure part, new we Proposed of 2 solution that new technology development. We'll suggest that the development is in the construct of higher stories APT more better other construction method. We expect that the new method is good but we have many things to solute themes. Thus, we decided that this development contents are needed that correct structural investigation and constructor's security of speciality and through a fact construct, correct verification.

This study verified the reliability and validity of the Korean version of the Student Career Construct Inventory(K-SCCI) that was translated into Korean language from the Student Career Construct Inventory (SCCI) developed by Savickas et al.(2018). To achieve this, this study conducted item content analysis, exploratory factor analysis, confirmatory factor analysis, and criterion-related validity in 530 university students. As a result of item content analysis and exploratory factor analysis, it was found that 4 factor models and 18 items were the most appropriate in K-SCCI. The 4 factors were named as crystallizing a vocational self-concept, exploring to gather information about occupations, deciding to commit to an occupational choic, and preparing to implement that choice. As a result of confirmatory factor analysis to verify the goodness-of-fit of the 4 factor models, it appeared to be appropriate. As a result of analyzing the correlation with related measures to verify the criterion-related validity of measures, it was found that student career construct was negatively correlated with employment anxiety but positively correlated with career adaptability.

The Basic Semantic Register(BSR) is and official ISO register designed for interoperability among eBusiness and EDI systems. The entities registered in the current BSR are not defined in a machine-understandable way, which renders automatic extraction of structural and relationship information from the register impossible. The purpose of this study is to offer a framework for designing an ontology that can provide semantic interoperability among BSR-based systems by defining data structures and relationships with RDF and OWL, similar meaning by the 'equivalentClass' construct in OWL, the hierachical relationships among classes by the 'subClassOf' construct in RDF schema, definition of any entities in BSR by the 'label' construct in RDF schema, specification of usage guidelines by the 'comment' construct in RDF schema, assignment of classes to BSU's by the 'domain' construct in RDF schema, specification of data types of BSU's by the 'range' construct in RDF schema. Hierarchical relationships among properties in BSR can be expressed using the 'subPropertyOf' in RDF schema. Progress in semantic interoperability can be expected among BSR-based systems through applications of semantic web technology suggested in this study.

Given that the culture of the mathematics classroom has been perceived as an important topic in mathematics education research, this paper deals with the construct of sociomathematical norms which can be used as an analytical tool in understanding classroom mathematical culture. This paper first reviews the theoretical foundations of the construct such as symbolic interactionism and ethnomethodology, and describes the actual classroom contexts in which social and sociomathematical norms were originally identified. This paper then provides a critical analysis of the previous studies with regard to sociomathematical norms. Whereas such studies analyze how sociomathematical norms become constituted and stabilized in the specific classroom contexts, they tend to briefly document sociomathematical norms mainly as a precursor to the detailed analysis of classroom mathematical practice. This paper reveals that the trend stems from the following two facts. First, the construct of sociomathematical norms evolved out of a classroom teaching experiment in which Cobb and his colleagues attempted to account for students' conceptual loaming as it occurred in the social context of an inquiry mathematics classroom. Second, the researchers' main role was to design instructional devices and sequences of specific mathematical content and to support the classroom teacher to foster students' mathematical learning using those sequences Given the limitations in terms of the utility of sociomathematical norms, this paper suggests the possibility of positioning the sociomathematical norms construct as more centrally reflecting the quality of students' mathematical engagement in collective classroom processes and predicting their conceptual teaming opportunities. This notion reflects the fact that the construct of sociomathematical norms is intended to capture the essence of the mathematical microculture established in a classroom community rather than its general social structure. The notion also allows us to see a teacher as promoting sociomathematical norms to the extent that she or he attends to concordance between the social processes of the classroom, and the characteristically mathematical ways of engaging. In this way, the construct of sociomathematical norms include, but in no ways needs to be limited to, teacher's mediation of mathematics discussions.

The purpose of this study was to propose curriculum and teaching sequence for seasonal change by exploring a learning progression. For the purpose, 4 steps of construct modeling approach (specifying construct, item design, outcome space, and measurement model) proposed by Wilson (2005) was applied. In the stage of specifying construct, 'length of shadow according to seasons', 'position of constellation according to seasons', 'seasons of the southern hemisphere and northern hemisphere', 'cause and phenomenon of seasonal change' were selected as the subconstructs of seasonal changes, and constructed a construct map showing the level of development from level 1 to level 4 for each subconstruct based on the results of the previous research. In the item design stage, we developed five assessment items consisting of 3 items in the form of C-E (choose and explain) and two items in the form of CR (constructed response), applied it to 383 elementary, middle and high school students. In the outcome space stage, the students' responses to the assessment items were categorized based on the construct map. The categories were classified into 4 levels according to student ability and scores of 1-4 were given. In the measurement model stage, we applied the partial credit model of the Rasch model and compared whether the learning pathway created from the results of students' response coincides with the construct map. Based on the results of the research, we modified the construct map and finally created hypothetical learning progression on seasonal change. Finally, we proposed an orientation of curriculum amendment and effective teaching sequence for seasonal change.

To establish transportation system in railway focusing truly, we should plan route and invest continuously to consider the means of railway's functional sides. And it should be inter-modal system. Therefore this study concentrates on high-speed railway and considers the construct of transportation system in railway focus on the supplier aspect.

Although the large-scale new socialist countryside construction has brought a opportunity for the rural landscape construction, it also impacted seriously the style of rural landscape. On the base of analyzing the advantages and disadvantages of new countryside construction, the paper proposed how to construct rural landscape in the construction tide.
