The Ministry of Education, Science and Technology has been developing the digital textbooks from 2007. But the evaluation criteria on the digital textbooks is not prepared, so it is difficult to develop excellent digital textbooks and to select superior ones. In this study, we researched into the concept, attributes and functions of the digital textbook in order to select the evaluation indicators, based on the literature reviews of digital textbooks, core evaluation measures and criteria were identified. And three methods were employed: a Delphi study, expert forums, and simulation tests. The results of these studies led the development of an evaluation criteria which consisted of four evaluation areas and 74 questions. The four evaluation areas consisted of content area, instrument design area, platform area and user area.

This paper deals with the questions: Are media user's activities labour? Or rent? These questions have provoked a debate in the critical media studies and Marx's theory. But it is not a matter of choosing either labour or rent. Even if user's activities could contribute to valorization, it needs some mediating process. Media Platforms-Google, Facebook, etc.-play a key role, and have to employ other forms of labour. Labour in media platform produces some capital commodities. In view of media platform, Smythe's audience commodity can be considered as capital commodity. Assertion in this paper expected to provoke new debate on media platforms and its labourer.

An elasto-plastic constitutive model was proposed, in which the behavior at small-to-large strain level can be modeled. The proposed model is based on the anisotropic hardening description with the generalization of isotropic hardening rule and the total stress concept. From a mathematical approach it was proved that the model includes the previous successful models. The model was verified by a series of resonant column tests, torsional shear tests and triaxial tests, and the proposed model predicted small-to-large strain behavior more consistently and accurately than the hyperbolic model and the Ramberg-Osgood model for a weathered granitic soil. In addition, the nonlinearity under small strain condition was predicted appropriately for the torsional shear test results.

The purposes of this study are to develop the formative assessment program in geometry area for a 1st-grade class of middle school and to test the effect of this program. This formative assessment program was based on mathematics curriculum for the 1st graders of middle school. In addition, we examined how the 1st graders of middle school understand the geometric concepts by analyzing their response in the pretest and the posttest. This formative assessment program and the results of its analysis would be the useful information for the effective teaching and learning in geometry area for the 1st grades of middle school.

이 연구의 목적은 우리나라 대기업 구성원의 사내기업가정신이 조직 몰입에 미치는 영향을 살펴보는데 있다. 이 목적을 달성하기 위하여 업종별 대표기업 3사의 구성원들을 대상으로 설문조사를 실시하며, 이를 토대로 상관관계 존재여부에 대한 분석 작업을 하고자 한다. 최근 IT 대기업 중심으로 스타트업의 혁신문화를 회사 내부로 유입시키려는 노력들이 급속히 증가하는 상황에서, 사내 기업가정신이 기업내부 구성원의 조직몰입에 미치는 영향을 실증적으로 분석하는 것은 시의 적절한 연구라고 판단한다. 조직몰입에 대한 연구는 최근 심리학뿐만 아니라, 경영학적 범위에서도 급속하게 확대되고 있다. 기업의 지속성장을 위한 전제조건은 조직구성원의 조직몰입을 통해 지속적인 경쟁우위를 확보할 수 있는 제품 및 서비스를 경쟁력을 제고시키는 것이다. 이를 위해 기업은 기존에 검증된 조직몰입의 선행변수에 대한 과감하고 지속적인 관리와 함께 새로운 선행변수에 대한 발굴을 시도하고 있다. 확인된 시장과 기업의 현실적 니즈에 근거하여, 본 연구는 사내기업가정신과 조직몰입간의 관계에 집중하였다. 이러한 연구목적을 달성하기 위하여 본 연구는 선행연구를 기초로 실증연구를 실시하였다. 문헌적인 연구는 선행연구를 개관하여 기업가정신의 각 구성요소와 조직 및 직무몰입에 관련된 국내외 발표된 논문과 저서들을 통하여 이론적인 배경을 검토하고 최근의 연구동향을 살펴보았다. 문헌연구로는 사내기업가정신과 조직몰입의 개념을 정리하고 구성요인을 고찰하였다. 실증연구는 삼성전자, SK텔레콤, 포스코의 현재 재직중인 구성원을 대상으로 설문을 진행할 예정이다. 설문결과에 대한 통계적 검증을 통해 각각의 구성요소의 유의성과 상관관계를 파악하고자 한다.

시맨틱웹의 구현 도구로써 온톨로지가 있다. 온톨로지는 지식개념의 의미적 연결을 하는데 사용된다. 영어 위키피디아를 토대로 한 영어 DBpedia 온톨로지는 스키마(owl파일 형태)와 인스턴스 모두 잘 구축이 되어있다. 그리고 영어 DBpedia의 각 Class에 한글은 레이블의 형태로 달려있다. 하지만 한글 레이블을 가지고 있지 않은 영어 DBpedia의 Class들이 절반이 넘기 때문에 한글 Class들만으로 된 스키마 구축은 의미가 있다. 한글 Class들로 만들어진 스키마가 있다면 두 한글 온톨로지 사이의 클래스 매칭 알고리즘을 위한 실험이나 한글 온톨로지 자동 증강 알고리즘의 연구 등에 유용하게 쓰일 수 있을 것이다. 본 논문에서 구축한 한글 DBpedia 온톨로지 스키마는 영문 DBpedia 온톨로지의 계층구조와 한글 클래스와 영문 클래스 사이의 매핑정보를 바탕으로 구축되었다. 그리고 기존에 제공되는 한글 DBpedia 온톨로지 클래스의 영어매핑 정보가 있는 한글 프로퍼티와 영어매핑 정보가 없는 한글 프로퍼티를 모두 한글 클래스의 프로퍼티로 입력해주었다.

This study examines the concept of the FRBR model of IFLA, which stratifies the bibliographic relationships between related works and bibliographic records and effectively links them, as well as the problems occurring in the applied cases. Moreover, it modifies the FRBR model by accepting the excluding perspectives of main entry heading and introducing ISTC as a linking device of the related work. This study examines the validity of the M-FRBR model by applying it to Korean literature, resettles the data elements of MODS based on the M-FRBR model. and realizes a bibliographic system based on the modified record format.

The purpose of this study was to understand social enterprise business operations experience converted from a self-sufficient enterprise. In-depth interviews with representatives of the 4 recycling social enterprises from self-sufficient enterprise which located in Chungbuk province were performed to collect data and analyzed by grounded theory method. As a result, configured 88 concepts and classified into 28 sub-categories 12 categories. According to a paradigm model, Core category, conditions, strategies and consequences were derived from the grounded theory. Especially, the core concept of enterprise management experience of the participants was 'An effort to overcome the harsh business conditions by pursuing sense of community and trying to secure its own competitiveness'. Based on the result, practical and policy proposal for management of the social enterprises were suggested.

This study is to suggest a method of constructing Informatics textbook considering the cognitive development level of middle school learners. We developed 3 types of learning content models according to the educational objectives and activities of learners and then suggested the methods of constructing textbook. For this, we reviewed the related research results on the development characteristics and cognitive development theories of middle school students. Second, we drew instructional schemes from the pedagogic theories. Then, we suggested 3 models: 'Learning Centered on Concept'. 'Learning Centered on Investigation', and ' learning Centered on Actual Training'. We suggested construction schemes to each model and verified the adequacy using questionnaire to 30 teachers and received the positive responses from most teachers.

The purpose of this paper is to disclose the characteristics of knowledge in the age of digital reproduction. To achieve this I extended Benjamin's concept of technological reproduction to three different stages as mechanical reproduction, electric reproduction and digital reproduction. Each stage has different degree of reproducibility and de-materialization. I also combined McLuhan's concept of the electricity at the point of de-materialization with reproducibility. The degree of materiality and reproducibility is the key concept which could scale the technical condition of knowledge production. The social condition of knowledge reproduction is controlled by economic and political factors. In this connection between technological and social condition the current knowledge production and intellectual property could be explained properly. This study could open the theoretical door to deepen such an understanding.
