This study examines the introduction of fractions in the third grade mathematics textbooks focusing on stages of units coordination and suggests alternative activities to help students develop their understanding of fractions. As results, the sessions of introduction units in textbooks was well organized to allow students to construct more extensive fraction schemes (i.e., Part-whole fraction scheme → Partitive unit fraction scheme → Partitive fraction scheme). However, most of the activities in textbooks were related to stages 1 and 2 of units coordination. In particular, the operations and partitioning schemes (i.e., equi-partitioning and splitting schemes), which are key to the development of students' fraction knowledge, were not explicitly revealed. Fraction schemes also did not extend to the Iterative fraction scheme, which is central to the construction of improper fractions. Based on these results, this study is expected to provide implications for the introduction of fractions in textbooks focusing on stages of units coordination to teachers and textbook developers.

앞으로 승용차용 타이어에도 전기냉장고나 세탁기 등에 부착되는 '에너지효율 등급표시'가 부착될 예정이다. 정부(지식경제부)는 지난 4월 5일 승용차 운행단계에서의 에너지소비효율(연비) 개선을 위하여 2011년 하반기부터 "타이어 효율등급제도"의 도입 계획을 발표하였다. 우리협회(대한타이어공업협회)는 동 제도의 원활한 도입과 효율적인 운영 및 정착을 위하여 적극 지원할 예정이다.

Process models are concerned with determining the key phases in the adoption process. therefore, process approaches strive to analyze the key steps or decisions in understanding how the innovation is successfully adopted. Objective in this study was to complement variance procedures with a process evaluation. Following are the major findings of this research. First, simply acquiring a new system does not automatically guarantee its successful adoption throughout the local government Second, problems with the adoption of a new technology is often based on human and organizational issues rather than on technical concerns.

해외 원전건설시장은 현재 전반적으로 침체국면에 있지만, 한중의 원전건설 기술수준은 계속 개발 발전단계에 있다. 한편으로 경쟁사간의 국제 정치적 역학관계가 민감하게 작용하고 있다. 따라서 초기단계에서는 기술도입선인 관련 있는 선진 외국 메이커와 하청 참여형태나 컨소시엄 형태로 기자재 공급에 참여하는 방안 등이 보다 현실적이다.

최근 10 여년 동안 교육 현장의 각 부분에 여러 가지 종류의 테크놀로지가 도입되면서, 교육의 내용과 방법에 있어서 점진적인 변화가 나타나고 있다. 예를들어, 수학 과목에 있어서는 그래픽 계산기, 도형 및 기하 학습 프로그램, 스프레드 시트, 함수 그래픽 프로그램 등의 도입으로 교과 과정 전반에 걸친 변화가 일고 있는데, 처음에는 이들 테크놀로지가 단순히 기존의 수업에서 수많은 반복을 요하거나, 지필식 방식으로는 정확하게 나타내기 어려운 도형이나 그래프를 빠르고 정확하게 그려내주는 보조수단으로 사용되었지만, 시간이 지나면서 이들 테크놀로지에 대한 활용도가 높아지게 되고, 이들 테크놀로지에 대한 교사들의 활용능력이 증대됨에 다라서, 이러한 테크놀로지가 단순한 보조수단에 머무르지 않고 주지에 기술이나 개념을 설명하는 방법 자체를 변화시키고 있다. 예를들어, 함수 교육에 있어서 그래픽 프로그램이 사용될 때에도, 초기 단계에서는 이들 함수의 개념을 설명할 때에는 거의 집합론이나 대수학적인 방법을 이용하였고, 최종 단계로 이들 함수를 좌표계 위에 표현하기 위한 보조수단으로 잠깐씩 사용되는 경우가 대부분이었으나, 최근들어서는 함수 학습의 초기과정부터 곧바로 이들 그래프 프로그램을 적극적으로 도입하여 학습자로 하여금 다양한 그래프 조작을 하게 함으로써, 어려운 집합론이나 대수학적인 개념을 도입하지 않고서도 함수에 대한 개념을 시각적으로 직관적으로 파악하도록 하는 학습 방안들이 제시되고 있는 것이다. 본 고에서는 현행 중고등학교 함수 교육 과정에서 그래프에 대한 다양한 조작 기능을 제공함으로써 학습자로 하여금, 제시되는 함수에 대한 시각적이고 직관적인 이미지를 가질 수 있도록 하기 위해서 개발된 ‘그래프 마법사’라는 프로그램을 소개하고자 한다.

While most of the previous information technology adoption and diffusion researches focus the critical factors not on the organizational perspective but on the individual perspective based on the various reasons such as informational characteristics. This paper will try to analysis the adoption and diffusion factors of the Internet related technologies based on the organizational perspective. Nowadays, in especially, the evolving and fast diffusing Internet related technologies and the flourishing e-commerce applications pressure retail banks that prepare the new types of online payment systems to maintain their existing and new customer relationship and compete with their potential competitors in the coming market environments. In addition, while most previous researches only focus on the adoption of new information technologies, this paper not only analysis the adoption of innovational technology but also analysis the diffusion process in an organization, which encourage practitioners and researchers to reveal more detail and practical analysis of the innovational technology adoption and diffusion process in ann organizational setting. Based on the previous researches, there are several factor-category will be selected for this research: 1) organizational factor, 2) within banking industry factor, 3) non-banking industry factor, 4) customer acceptance factor, 5) government factor, and 6) the functionality of e-commerce systems factor. Finally, in this study, we assumed that the more sophisticated e-commerce adopting banks provide the more broad range of banking services in general. Thus, we develop the extended integrated technology diffusion model to provide empirical evidences to distinguish between adopters and non-adopters and explain the diffusion levels of e-commerce using the level of services provided via Internet to the customer in retail bank industry.

Public Shared Service Centers (PSSC) consolidate functions such as human resources, information technology, financial management or accounting into one office to serve an organization. A prominent example from the United States is the Federal Information Technology Shared Services Strategy. It supports mission, administrative, and infrastructure-related IT functions through providing organizations in the Executive Branch of the Federal Government (Federal Agencies) with policy guidance on the full range and lifecycle of intra- and inter-agency information technology (IT) shared services. This study looks at the Federal Information Technology Shared Services Strategy in order to draw lessons for fostering collaborative government through the use of PSSC. It finds the following factors are critical for success when implementing IT shared services: (1) agency leadership must be solidly behind their IT shared service plan, or the needed changes will not happen at the business unit, program, or system levels; (2) there must be a move away from internally-centered, program-specific thinking, and a move toward a paradigm of consuming and providing IT shared services with multiple groups whenever possible; and (3) successfully managing "loss of control" issues is central, and optimizing business processes is essential to move from stove-piped workflows to processes that work across the agency enterprise and beyond. Therefore, the study suggests that a Korean model of PSSC implementation be introduced, and that good IT Governance is a crucial component of PSSC strategies.

Since 1995 many enterprises have introduced ERP to strengthen competitive power. However, enterprises that have introduced ERP for the first time have experienced various types of problems integrating them; to this day, there are only a few enterprises that have implemented ERP successfully. The main reason for the failures of successful ERP implementing is that enterprises frequently ignore and/or don't know how to systematically evaluate the construction process of ERP and busy finishing a phase without resolving problems before going on to the next phase. This research focused on the implementation process of ERP project to evaluate the process of ERP at each phase. As a result, we propose an evaluation model of ERP project as a tool to find critical problems at each phase and improve on how to resolve the problems found at each phase. This evaluation model makes it possible to introduce ERP successfully by presenting the basis of assessment which will be used by enterprises to minimize the trial and error of construction process of ERP.

인터넷 기술의 발달에 따라 교육분야에서도 이를 도입하고 있다. 또한, 웹을 기반으로 하는 문제학습 시스템에서는 피험자의 학습효과를 높이려는 방법으로 학습결과를 반영하는 문항분석 이론이 연구되고 있다. 그러나, 기존의 웹 기반 학습시스템은 대부분 일방적인 학습내용의 제공이나 반복적인 학습에 그치고 있어 학습자의 학습효과를 기대하기 어렵다. 본 연구에서는 문항분석이론 중 문항난이도를 이용한 학습단계별 웹 코스웨어를 설계 및 구현하였다. 학습단계 설정은 문항난이도의 결과에 따라 상.중.하의 단계로 나뉘어 학습자가 학습을 하기 전에 선택 할 수 있도록 하였다.

In the planning phase of domestic urban environment maintenance and improvement projects, a particular problem is the increase in service expenses and project cost with the establishment of plans under circumstances that exclude the residents or have incomplete consent from them and the public organization. This delays the promotion of the project. This study aims to resolve such problems by proposing a measure to introduce a privatepublic consultative body for residents and the relevant departments of the public sector, to encourage them to participate and establish plans together from the beginning. This is expected to contribute to the smooth promotion of the project, as it would remove the conflicting factors that are expected to be generated in the project implementation phase before they could emerge.
