Knowledge graph is a technology that improves search results by using semantic information based on various resources. Therefore, due to these advantages, the knowledge graph is being defined as one of the core research technologies to provide AI-based services recently. However, in the case of the knowledge graph, since the form of knowledge collected from various service domains is defined as plain text, it is very important to be able to analyze the text and understand its meaning. Recently, various lexical dictionaries have been proposed together with the knowledge graph, but since most lexical dictionaries are defined in a language other than Korean, there is a problem in that the corresponding language dictionary cannot be used when providing a Korean knowledge service. To solve this problem, this paper proposes an ontology based on the parts of speech of Korean. The proposed ontology uses 9 parts of speech in Korean to enable the interpretation of words and their semantic meaning through a semantic connection between word class and word class. We also studied various scenarios to apply the proposed ontology to vehicle services.

The design of injection molded prlymeric parts has been done empirically, since it requires profound knowledge about the moldability and causal effects on the properties of the parts. This study shows CAE approach for the design of the seat frame of fiber-reinforced composite material in order to realize the concept os rationsl design for the productivity and quality of mold making. The knowledge-based CAE system is constructed by adding the knowledge-basw module for the design evaluation and appropriate CAE programs for mold design analysis in order to provied designers, at the initial design stage, with comprehensive process knowledge for the performance analysis and the design evaluation. A knowledge-based CAE system is a new tool which enables the concurrent design with integrated and balanced design decisions at the initial design stage of injection molding.

In this paper, we propose a framework for ontological knowledge-based image understanding systems. Ontology composed of concepts can be used as a guide for describing objects from a specific domain of interest and describing relations between objects from different domains The proposed framework consists of four main subparts ⅰ) ontological knowledge bases, ⅱ) primitive feature detectors, ⅲ) concept inference engine, and ⅳ) semantic inference engine. Using ontological knowledge bases on various domains and features extracted from the detectors, concept inference engine infers concepts on regions of interest in an image and semantic inference engine reasons semantic situations between concepts from different domains. We present a outline for ontological knowledge-based image understanding systems and application examples within specific domains such as text recognition and human recognition in order to show the validity of the proposed system.

With the advent of knowledge-based economy and information society, information and telecommunications(IT) industry is reckoned as the crucial sector for the creation and diffusion of technological knowledge. In this study, we analyze the process of 'industrialization of IT'and 'informatization of industries' based on the technology linkage structure, or technological knowledge network. The former is defined as the process whereby IT industry absorbs technological knowledge from other industries to grow as an independent industrial sector. The latter is defined as the process whereby other industries adopt IT technology to enhance productivity and upgrade industrial structure, We employ the R&D stock as a proxy for technological knowledge of respective industries and measure the flow of technological knowledge between industries in terms of I/O relationship. By applying the network analysis, we examine the changing pattern of technology linkage structure of the Korean industry throughout the years from 1983 to 1997. Some policy implications are presented based on the findings from the analysis.

This paper presents a knowledge-based view of the multi-business firm. The multi-business firm has advantages in technological innovation and knowledge creation to the extent that it embodies various ideas and resources, and recombines them more effectively and efficiently than market contracts. The purpose of this paper is to identify how to organize the multidivisional form (M-form) structure to realize such advantages. We first differentiate within-division innovation and cross-division innovation, and explain why cross-division innovation, despite its higher performance potential, would be more difficult to achieve, compared to within-division innovation. Then, we offer the propositions about how to promote cross-division innovation with references to resource capability and coordination capability that is, in turn, composed of structural and control system, social capital, and human resource management system. We conclude by discussing theoretical and practical implications.

Comparing to the other subject, hierarchy among mathematical contents is strong from the perspective of knowledge order as grades go up. That is, the knowledge that students already have learned, are learning and will learn are closed related from grade to grade. We expect students to be proactive and creative in studying mathematics, which is the goal of 21th century, analyzing their. knowledge structure based on the hierarchy of knowledge through assessment. Especially, using computer system we provide students with substantial feedback for the assessment as well as objective validity is increased along with speedy and exact process in a bid to help students' mathematical understanding grow. This paper seeks to analyze the assessment data by applying knowledge spaces to computer system and develops efficient methods based on the analyzed results, to diagram each student's knowledge structure.

An architectural pre-design, which is conducted prior to the architecture design, supports fundamental configuration during the entire AEC project by predicting the cost, demand, etc., of the building, and is therefore gaining importance. In particular, the massing calculation of the pre-design phase should be prioritized, as it is fundamental to architectural outline. However, most architects depend on only their experience and intuition while conceptualizing an integrated framework of design conditions, including the building code and requirements for the massing calculation of the object. Therefore, many difficulties arise in terms of performing appropriate tasks. Thus, the purpose of this study is to implement a knowledge-based BIM for explicitly representing the design knowledge, which is the basis of decision making for an architect while performing the massing calculation. In particular, the 3D knowledge relevant to a project can be provided and accumulated in the massing calculation by the BIM system; this facilitates an integral understanding. Consequently, the approximate result of massing calculation in 3D BIM environment, through both the knowledge-based BIM template and plug-in, can be swiftly provided to the architect. In addition, the architect can invent various alternatives, estimate resulting costs, and reuse the accumulated knowledge in future BIM design processes.

The purpose of this study is to present an objective basis for the entry point of a knowledge-based economy, that is used by quantitative analysis to serve as 'The Result of Wage Structure Survey' and 'Sample Design for Survey Report on Labor Conditions by Employment Type' of the Ministry of Employment & Labor. Entry criteria for a knowledge-based society, through the definition of a Bell and Toffler, was defined by the number of information workers more than the number of physical workers, and the information workers were classified by knowledge workers. To redefine the definition of Porat's typology of information workers, Korea Standard Classification of Occupation is classified by the job of knowledge, service, industry and agriculture. The result of the analysis is appeared the entry point of a knowledge-based economy by workers structural changes and annual wage structure changes has identified empirically-year 1980 the United States more than 20 years later in 2000. In addition, the economic contribution of knowledge occupation was confirmed to be the biggest by measuring the economic contribution of occupation classification in the knowledge society.

The purpose of this study was to identify the effects of simulation-based education regarding care in a cardio-pulmonary emergency care as related to knowledge, critical thinking, and problem solving ability in nursing students. The study was conducted with a nonequivalent control group pre-posttest design. Seventy four participants were assigned to either the experimental group(34) or control group(40). The simulation-based cardio-pulmonary emergency care education included lecture, team-based practice, and debriefing, and it was implemented with the experimental group for a week from September 1 to December 11, 2015. Data were analyzed using chi-square, t-test and ANCOVA by using SPSS 21.0 program. The experimental group who had the simulation-based education showed significantly higher knowledge(F=24.930, p<.001), and critical thinking(F=5.951, p<.05) for cardio-pulmonary emergency care compared with the control group who had traditional education. However, there were no significant differences in problem solving ability(F=3.327, p>.072). The results indicate that a simulation-based education is an effective teaching method to improve knowledge and critical thinking in nursing students learning cardio-pulmonary emergency care. Further study is needed to identify the effect of a simulation-based team positive education program of nursing students.
