The reference guide for the cost of establishing the digital documents has been used as a basis for establishing the budget for the construction of the knowledge information resource. However, due to the abolition of the nominal unit price notification in terms of IT projects, it is necessary to conduct research to convert the standard of the current labor force grade standard to the national incompetency standard (NCS). In this study, we investigate and revise the system and contents of the current knowledge information cost estimation model. In specific, i) we conducted gap analysis of cost estimation model and existing NCS model. As the contents conforming for the construction of the knowledge information resource were not adoptable, we define the description of the construction of the knowledge information resource and to identify the core elements of NCS prior to the improvement of the cost model. ⅱ) then we proposed improve the cost model considering integration with newly proposed NCS model for knowledge information construction job. In order to ensure the validity of the application of NCS development and cost estimation model, the experts reviewed relevant contents and made plans for improvement by using experts from supply and demand groups of various fields of national knowledge informatization projects.

Managing and reusing knowledge in engineering and construction sectors can lead to greater competitive advantage, improved designs, and more effective management of constructed facilities. The use of Information Technology (IT) in design and construction can exploit strategic opportunities for new ways of integration, sharing and facilitating information and knowledge in any field of engineering. The integrating of separate areas of IT can be used to bring a group of experts and specialists in any field of engineering closer together by allowing them to communicate and exchange information and expertise that facilitate knowledge capture, sharing, and reuse. A lack of an advisory management system and a need to marshal all available data in a common format has indicated the need for an integrated engineering computing environment to investigate concrete repair problems. The research described in this paper is based upon an evaluation management system (EMS) which comprising a database management system (REPCON) alongside visualisation technologies and evaluation system (ECON) is developed to produce an innovative platform which will facilitate and encourage the development of knowledge in educational, evolution and evaluation modes of concrete repair. This allows us to create assessment procedures that will allow the current condition of the concrete structure and its components to be expressed numerically using a confidence level (CL) so as to take the best course of action in the repair and maintenance management. The explained rating system, which is related to structural integrity and serviceability of the structure, allows the confidence level to be determined by visual inspection and the descriptive information and pictures taken from an available REPair of CONcrete (REPCON) database.

Purpose: This study was designed to analyze recent trends in research about caregivers of hospitalized children in Korea and to suggest future research directions in this area. Methods: Eighty one studies selected from http://www.kan.or.kr, www.childnursing.or.kr, www.riss4u.net, and www.ndsl.kr published from 1995 to 2011 were used. The analysis framework of concepts was derived from client domain (Kim, 2000) and knowledge type (Kim et al., 2004). Results: In terms of research design, nonexperimental studies (82.7%) were the most frequent, followed by experimental studies (14.8%) and qualitative studies (2.5%). Mothers were the most frequent caregivers, and hospitalization was the most frequent health problem of the children. In terms of categories of the concepts, 35 (39.3%) studies included essentialistic concepts like coping and adaptation, 15 (16.9%) studies included problematic concepts like anxiety and uncertainty, and 39 (43.8%) studies included health-care experiential concepts like educational needs and nursing needs. In term of knowledge types, there were 35 (39.3%) studies of the explanatory knowledge type, 44 (49.5%) descriptive ones, and 10 (11.2%) prescriptive ones. Conclusion: The results indicate that further research is necessary on problematic concepts and prescriptive knowledge types for child health nursing practice which will lead to expanding nursing knowledge.

The purpose of this study is to analyze the multiplication units in the elementary school mathematics. In the 2015 revised curriculum, students learn multiplication in $2^{nd}$ grade. The multiplication units is divided into two: multiplication and multiplication facts. In these two units, we mainly analyze situations involving multiplication, models for teaching multiplication, and multiplication strategies for teaching multiplication facts in relation to Subject Matter Knowledge. We called these contents Multiplication Matter Knowledge. We examined the precedent study with regard to multiplication at the elementary mathematics. As results, we prepared an analysis framework for this study. This study was conducted according to qualitative research methods, expecially 'qualitative contents analysis'. The contents here refer to Multiplication Matter Knowledge that can be found in the elementary mathematics textbooks and working books etc. As results of analysis, We can confirm that various multiplication situations and multiplication models are presented in the textbooks. And it has been examined that various multiplication properties are presented in the textbook according to the multiplication strategy levels. We insist elementary school teachers should be aware of these Multiplication Matter Knowledge. This study aims to provide elementary school teachers with basic data in these contexts.

웹을 통한 데이터 공유에 대한 관심의 증가로 RDF 트리플 형태의 데이터가 폭발적으로 증가하고 있다. 대용량 RDF 데이터를 저장하고 빠른 SPARQL 질의 처리를 지원하는 트리플 저장소의 개발이 중요하다. 아파치 프로젝트 중 하나인 Jena-TDB는 가장 잘 알려진 오픈소스 트리플 저장소 중 하나로서 Jena 프레임워크 기반으로 구현됐다. 하지만 Jena-TDB 의 경우 단일 컴퓨터에서 작동하기 때문에 대용량 RDF 데이터를 다룰 수 없다는 문제점이 있다. 본 논문에서는 MongoDB를 활용한 Jena 프레임워크 기반의 트리플 저장소인 Jena-MongoDB를 제안한다. Jena 프레임워크를 사용했기 때문에 기존 Jena-TDB와 동일한 인터페이스로 사용할 수 있고 최신 표준 SPARQL 문법도 지원한다. 또한 MongoDB를 사용했기 때문에 분산환경에서도 작동할 수 있다. 대용량 LUBM 데이터셋에 대한 SPARQL 질의 처리 실험결과 Jena-MongoDB가 Jena-TDB 보다 빠른 질의 응답 속도를 보여줬다.

The study aims to investigate the antecedents affecting purchase intention in the category of green skincare products. Many studies have used the theory of planned behavior to investigate factors affecting intention to purchase products in general. This paper not only retests the influences of attitude, subjective norm, perceived behavioral control on the intention to buy eco-friendly skincare products but also suggests a new antecedent - environment knowledge of purchase intention. More importantly, this study is the first to propose the moderating effect of country of origin and product knowledge on the relationship between attitude and purchase intention. This study employs a sample of 350 female customers from 18 to 39 years old in Ho Chi Minh City. The research applies the Multiple Linear Regression to analyze the proposed hypotheses in the conceptual framework and results in significant outcomes. The result shows that attitude is the most influential factor then, subjective norm, perceived behavioral control and environmental knowledge. Most importantly, the findings of this study suggest that product knowledge is found to moderate the effect of attitude on purchase intention. The finding of moderating effect is a new contribution to the literature and future research can be carried out to validate this result.
