This study aims to identify the student assessment competency of the three elementary science teachers and investigate strategic measures to improve them. The study progressed as a qualitative case study method. A self-awareness checklist and in-depth interviews were conducted to collect data. The data analysis was reviewed and agreed upon by two process-focused assessment-leading teachers and two elementary science education experts. Consequently, the level of self-awareness of student assessment competency of the three participants was relatively high. However, the scale average of the feedback area was the lowest on average. The student assessment competency of the participants showed different levels and characteristics. Additionally, some inconsistencies between perception and practice were found. Strategic support and education are needed to enhance elementary science teachers' student assessment competency, and the development of self-diagnosis tools should proceed.

Post-evaluation system reflects the results of performing a public construction project in the future similar public construction projects to be utilized in the planning. However, the current system simply compares the expected values, such as demand, B/C ratio, cost of construction, construction period, with the actual values after the completion of construction. In addition, most public owner does not actively conduct the post-construction evaluation tasks, so that the evaluation results has not been returned to early stage of a construction project. In this study, status of the post-construction evaluation system is investigated by a survey of the public owner and the construction project evaluation system of the United States and Japan was analyzed. This paper presents the improvement scheme of utilization of the results of the post-construction evaluation system. Through improving the post-construction evaluation system, it is expected that public agencies would easily utilize the post-construction evaluation.

본 연구는 성과관리가 조직의 지속적인 성장과 발전의 혁신도구로써 조직성과에 영향을 미친다는 측면에서 공공부문의 균형성과표(BSC) 운용의 성공요인과 고려사항을 바탕으로 연구모형을 설정한 후 이를 실증적으로 분석하였다. 이를 위하여 성과관리를 위한 BSC의 추진 관리 단계인 계획, 실행, 평가, 환류 등 순환주기에 관련된 변수들을 독립변수로 하고, 조직성과에 관련된 변수들을 종속변수로 선정하여 독립변수가 종속변수에 미치는 영향을 분석하였다. BSC를 구축 운영하고 있는 공공기관의 BSC 성과관리시스템 담당자에게 설문조사를 실시하여 분석한 결과, BSC 운영 단계별 하위변수들은 상호간에 영향을 미치며, 조직성과에도 유의미한 영향을 미치는 것으로 나타났다. 이러한 분석결과에 따른 정책적인 시사점은 성과관리를 조직 내에 촉진 유지하기 위한 조직적, 정책적, 전략적 환경을 조성하여야 한다는 점이다. 또한 공공부문에서 성과관리제도가 실패하는 가장 큰 이유는 객관적인 평가지표가 명확히 설정되지 않았거나 보상체계가 불충하기 때문이다. 공공부문의 경쟁력 확보를 위해서는 구성원이 전략적 사고의식을 가져야 한다.

In order to achieve competitive business goals, every enterprise needs to evaluate the current level of IS(information systems) performance and their utilization. The evaluation is to measure technical capacity and operational capability of enterprise information systems and to diagnose their effectiveness of business goals and efficiency of resources. Furthermore, organizations need to apply information technology(IT) proactively instead of reactively. However. it is usually very difficult for an enterprise to accumulate knowledge acquired during construction of the information systems and apply it to maintain and evaluate them. Also. most researches regarding evaluation are limited in some parts of evaluation fields, the most prominent being lack of the entire views and integrated relationships of enterprise activities. This dissertation develops an integrated evaluation system, which is based on the continuous improvement model of information systems performance. that effectively measures the level of enterprise information systems performance. enabling enterprises to achieve their goals of information systems and related business strategies. The contents of this work are composed of the continuous improvement model of information systems performance, an integrated evaluation system for IS performance and case study.

Recently, in South Korea, security management has been strengthened, but there have been an increasing number of cases where the main infrastructure of the country is hacked in the cyber space. South Korea is equipped with sophisticated information and communication technologies, such as Internet, but is threatened by cyber terrorism of North Korea and terrorist organizations. Nevertheless, there is a limit to how to develop a policy and strategic plan for the country, which is related to domestic terrorism and lacks legal and regulatory facilities, and therefore, in this study, proposed suggestions for building adaptive and efficient policy formulation. Based on the theoretical analysis framework of the Strategic Plan for achieving the objectives of the research, we compared the UK 's security strategy with the national security policy of the domestic government. As a result, several problems were derived: First, the domestic security strategy did not take into account the external environment. Secondly, lack of coordination with domestic cyber security goals setting and strategy is causing ambiguity and confusion. Third, the detailed plan of implementation of national security in each province is designed to ensure that there is a possibility that a mixed side effect between ministries and agencies will arise. Fourth, it was found that there was a limit to prepare the evaluation standards for the evaluation and return of domestic security policies in the country. Therefore, in order to establish a policy for the response of domestic cyber terrorism, we set up a vision from long-term perspectives and concrete targets based on the strategic approach of the security policy, It is necessary to present an assignment and formulate an efficient execution plan. It is necessary to maintain and improve the domestic safeguards in order to be able to complement the problems through evaluation and feedback.

In this paper, we introduce an integrated performance evaluation model defined by the three indices (evaluation index for each evaluation stage, performance viewpoint, and performance type) and analyze the utilization and satisfaction of the seven public u-IT services implemented from 2008 to 2009 using the proposed model. From the performance results of the public u-IT services, it was found out that most of the research goals initially set by the public u-IT service support projects were satisfied. Furthermore, we suggest improvement directions and promotion strategies of future projects.

Meta-evaluation for national R&D programs should be established within the framework of whole R&D system linked with science and technology needs and objectives. The R&D program evaluation system can be understood as a circulation of input, implementation, output, and utilization. In the result of the Delphi survey, which consisted of twenty-four experts (performed in three rounds), twenty-four indices were developed. The meta-evaluation model included sub-items which were important points of view of it as follow (eight items): propriety of planning, sufficiency of information, and propriety of evaluators in evaluation input; appropriateness of method and appropriateness of procedure in evaluation implementation; credibility of output in evaluation output; and usefulness of report and application of evaluation utilization. As the application of the meta-evaluation model, the total mean was lower than 3.0 of the median value of 2.73 (5 point Likert scale). Finally, it was suggested that the feedback of evaluation results should be more enforced to R&D program improvement particularly (evaluation utilization 2.50).

This study focuses on the development of dynamic assignment for evaluation and application for dynamic route guidance strategy. Travelers are classified according to information contents which they received pre/on trip. The first group have no traffic information, so they travel with fixed route. The second group have real-time shortest path and travel according to it. The last group have car navigation system or individual method(cellular phone, PDA-two way communication available) for traffic information on trip. And then they are assigned in accordance with the proposed multiclass dynamic assignment model. At this time the last group is gotten under control with DFS(decentralized feedback strategy). In use of this Process we expect that various traffic information strategy can be tested and also be the key factor for success of ITS, location of VMS(variable message sign), cycle of information, area of traffic information, etc).

A comprehensive evaluation of cardiac function includes information in relation to cardiac output and systemic venous return. The heart is composed of four chambers: two atria and two ventricles, each with its own unique mechanical function. These four cardiac chambers, their valves, and the pulmonary circulation system are inter-related as they preload or afterload on each other. Cardiac dysfunction is a failure of global cardiac function, resulting in typical clinical manifestations. To investigate the underlying cause of cardiac dysfunction, a step-by-step evaluation of cardiac blood flow tracks is necessary. In this context, imaging markers showing details of the cardiac structures have an important role in assessing cardiac function. An image-based evaluation allows for investigation of function in terms of individual cardiac components. Evaluation of cardiac function using cardiac CT has recently been validated. This review aimed to discuss cardiac CT-based imaging markers for comprehensive and detailed cardiac function assessment.
