The purpose of this study was to develop and verify the feedback-enhanced performance assessment model through a variety of assessment strategies focused on the development of students. In order to achieve the purpose of this study, we analyzed the achievements of the sixth grade curriculum standards and set the central achievement standards in core competencies. We then established an evaluation plan to take advantage of a variety of methods and develop an assessment tool for process-based evaluation during lessons. We applied this assessment model to 6th grade students while teaching and learning mathematics in the classroom. The result of applying the performance evaluation model showed the improvement of students' reflective thinking ability. Also, some students who was not achieved at the level of 'N' could develop to the level of 'N + 1'. A long term research using various assessment strategies should be continued for effective help of students' mathematical development.

Objectives : The new health technology assessment (nHTA) involves evaluating the safety and efficacy of the new health technology under the Medical Services Act by the New Health Technology Assessment Project Division from 2007. The purpose of this study is to understand the status of applications and recent trends of the results, and suggest strategies for the development of new health technologies in Korean Medicine. Methods : We investigated and analyzed the results of evaluation of new health technology of whole conventional medical and the list of new health technologies in Korean Medicine provided by the New Health Technology Assessment Project Division from 2007 to 2016. Results : The number of applications for new health technology of Korean medicine was low as 41 items in the whole number of 2,013 items. The evaluation method of new health technologies in both, the whole medical and Korean medicine fields was the same, but the tendency in results was very different. Most of the new health technology items in Korean medicine were classified as existing technology (20 items), early stage technology (7 items), and Only 2 items were evaluated as research stage technology. Conclusions : In order to develop new health technology in the Korean medical field, we have made suggestions about the health technology assessment systems, R&D infrastructures, and corporation with conventional medicines.

We believe new assessment strategies and practices need to be developed that will enable teachers and others to assess students' performance in a manner that reflect the 7th Korean curriculum reform vision for school mathematics. This research was conducted to develop the assessment tasks based on the current literatures such as National Council of Teachers of Mathematics (1999) and Korea Institute of Curriculum & Evaluation(KICE, 2002, 2003) in quadratic functions of the secondary school and to find the effect of these tasks by classifying students' responses. The research instrument were composed of three criteria, the previous knowledge, the application of quadratic functions, and the general properties in functions. The research data were collected from 32 high school students in a suburb of Seoul and sorted by their similarities and differences in mathematical understanding. Through the research, we could know more than ever before about how the students learned mathematics and about how to improve teachers' mathematical instruction.

The security risk management used by some service providers is not appropriate for effective security enhancement. The reason is that the security risk management methods did not take into account the opinions of security experts, types of service, and security vulnerability-based risk assessment. Moreover, the security risk assessment method, which has a great influence on the risk treatment method in an information security risk assessment model, should be security risk assessment for fine-grained risk assessment, considering security vulnerability rather than security threat. Therefore, we proposed an improved information security risk management model and methods that consider vulnerability-based risk assessment and mitigation to enhance security controls considering limited security budget. Moreover, we can evaluate the security cost allocation strategies based on security vulnerability measurement that consider the security weight.

Appropriate strategies are needed to ensure long-term preservation of various types of electronic records. For proper preservation of electronic records, it is necessary of decision-making processes for risk assessment, notification and implementation of conservation measures. To do this, the task of assessing various risk factors that impede the long-term preservation and utilization of electronic records should be done first. In this study, since electronic records are mostly stored in file form, risk assessment for electronic records of file type is performed. The risk factors required for the risk assessment of the file format are derived, and the algorithms are developed to devise a calculation method of the weighting factor and the risk factor index for evaluating the risk based on the proposed risk factors. In addition, the proposed methods are applied to the file formats used in Korea and risk assessment is performed and the results are analyzed.

The purpose of this study is to develop a Framework for Performance Assessment in Science Education(FPASE). Science educators in the past have paid more attention to science curriculum and teaching strategies than assessment. In recent years, attention has turned toward performance assessment which addresses the concerns of science curriculum and instruction, and which is consistent with goals of science education at various levels of interests. Science educators are trying to do performance assessment, yet they don't have a framework that is highly qualified in terms of science educational objectives for the future, and advantages of performance assessment. We, therefore, have developed a framework for performance assessment in science education, which may be useful for science teachers to understand and assess their students' abilities. We have extracted seven domains covering students' various abilities as the important objectives of science performance assessment and grouped them into three categories: General, Science specific, and Intermediate abilities. And we developed a F-PASE with a three dimensional solid figured structure, and illustrated it as the configuration of a com. F-PASE is useful for science teachers to develop and select a science performance assessment as well as have a more advanced understanding of their students' abilities. It is a creative and novel assessment framework in terms of structure, configuration, functions and meanings. It also suggests a new vision of an assessment framework in science education.

At present, the health risks associated with the natural radionuclides of ground water have become a concern as potential social problems. However, there are no regulatory actions or control strategies for such risks. Therefore, we have investigated and discussed the risks and associated management strategies for radionuclides in other countries. US EPA has proposed MCL (300 pCi/L) and AMCL (4,000 pCi/L) for radon, and 30 ppb for uranium, 15 pCi/L for gross-alpha and 5 pCi/L for radium as final MCLs. Also, Canada, WHO and European countries have their inherent management levels. Finally, we suggested several criteria for setting guidelines in our countries including exposure related criteria such as geological distribution, occurrence, exposure probability distribution, exposure population and multimedia exposure assessment, acceptable risk, and cost -benefit analysis. The national-scale exposure and risk assessment, and economic analysis should be conducted for producing and aggregating the representative information on these criteria.
