  • The purpose of this study was to find the relationship between elementary school teachers' beliefs of inquiry and science performance assessment. To collect data for analyzing elementary school teachers' beliefs of inquiry and their practice of science performance assessment, the researcher was surveyed with elementary school teachers by open-ended questionnaires and interview. The findings of this study were as follows; First, Most of elementary school teachers beliefs of inquiry was shown as constructivist tendency. This view of inquiry involves watching and doing experiments, and the skills of thinking processes, in which learners make their own interpretations rather than merely acquiring preexisting knowledge structures. Second, for content knowledge, participants' preception about the target of science performance assessment involved assessing application of science knowledge rather than basic level of substantive knowledge. For inquiry process, participants' preception about the target of science performance assessment involved assessing the lower level of inquiry rather than the higher level of inquiry. Most of participants was measured using a paper and pencil test for the actual evaluation methods due to the ease and objectivity of the assessment, the lack of understanding how to perform the performance evaluation process and method. Especially, participants who recognize that the higher level of inquiry was used performance and informal mode of assessing.

  • The benefits of pesticides in improving the food quantity and quality requirements for an increasing world population are significant, and they can be described in agronomic, economic and social terms. The risks are assessed from the hazards which are likely to occur in practice ; the hazards are defined by the toxicity of the pesticide to non-target organisms at various exposure levels. There are ways of reducing the risks (mainly by reducing exposure in practice) and improving the benefits of pesticides ; these are known as risk management and benefit management respectively. The overall risk-benefit assessment is facilitated if each component can be expressed in financial terms, but it must be made nationally or locally on a sound technical basis against the prevailing agronomic, socio-economic and political circumstances. Paraquat is used to illustrate the risk-benefit assessment process in general terms, and the conclusion is that the benefits greatly outweigh the risks. It is important to keep the risks of pesticides in perspective with those associated with other naturally occurring chemicals in our diet and with other everyday aspects of life. In an overall context, the pesticide risk is small.

  • Purpose: The study was done to investigate physical assessment skills used by, and educational needs of, advanced practice nurses (APNs) and nurse specialists in Korea. Methods: A total of 123 APNs and nurse specialists working in five major hospitals in Seoul were surveyed from July 15 to August 20, 2007. Results: Fourteen skills out of 126 items were reported as being performed on a regular basis by participants. The majority of these skills involved general observation. Forty-six skills were rarely used. Some participants showed a lack of confidence in certain assessment skills, such as in doing a rectal or pelvic exam, and the use of some assessment equipment. Over 90% of participants required in-depth education on health assessment provided by specialists or nursing professional organizations. Conclusion: More educational opportunities in physical assessment should be provided including education programs based on the nurses' skill levels and needs. This effort will help to increase confidence of APNs and nurse specialists in physical assessment skills, ultimately resulting in better nursing outcomes.

  • In this study, we developed an elementary science performance assessment material on STS theme, especially the respiration. The material is constituted with 3 components, which are performance task, students' response format and scoring system, and it also has various objective domains such as applying science knowledge, improving science attitude, using ICT, communicating and reflective thinking. It offers teachers a tool by which they can assess students' abilities on a whole. The task is made with the motivation-evoking content of 'No Smoking'. It is constructed on the activity of writing a letter to his/her father not to smoke. The students' response format is made by problem solving process, and the scoring system is matched with the steps of students' response. The material involves several theoretical backgrounds and the strengths of performance assessment. In addition, due to the detailed students' format and scoring system, it can be used practically in elementary science classroom.

  • The purpose of this study was to analyze reports from research middle schools based on the criteria for process-focused assessment to find out how the characteristics of process-focused assessment were being implemented in middle school science classes. The analysis criteria for the characteristics of process-focused assessment (integration of lessons and assessments, evaluation elements and methods, content and timing of feedback, and learner growth management) were extracted. Using the analysis framework, the result reports of seven research middle schools for process-focused assessment were analyzed. In terms of integration of lessons and assessments, when the process-focused assessment was operated, the class and evaluation plan were well implemented based on the curriculum achievement standards, but the process-focused assessment was recognized as a performance evaluation. In terms of evaluation elements and methods, the evaluation element for knowledge was the main component, and competency was presented in the planning stage, but competency was not dealt with in class execution. The evaluation method was biased toward teacher-centered observation evaluation and written test, and the setting of scoring criteria for each evaluation element was insufficient. In terms of the content and timing of feedback, feedback was mainly provided based on achievement confirmation, but no case was found in which scaffolding was provided at an appropriate time for insufficient parts in the learning process. In terms of the learner's growth management, the competencies cultivated through science classes were included in the detailed subject specialties of the school record. However, little was shown in the report on how to systematically manage the process of developing learners' competencies and reflect the evaluation results to teachers' class improvement.

  • The hazard assessment in which the potential hazard factors in the buildings are investigated and the scale of the hazard is analyzed should be performed first in order to prevent personal and material damages due to building fire. In this study, the building fire hazard are assessed using 822-item checklist, for the qualitative evaluation of which the main factors are classified into 10 items, yielding 100 scale points with some weighting. It is shown that present model is applicable for the assessment of all general buildings through the examination of the suitability of assessment model by actual assessment of existing building. Also, the checklist is prepared in itemized questionnaire form for easy assessment of building fire hazard. Therefore, the present model will be helpful for those working in fire prevention, who are suffering from the lack of manifest evaluation model for the fire prevention assessment so far in Korea.

  • In relation to the utilization and disposal of dredged sediment caused by coastal dredging project, we diagnosed the status of legal standard and system, and proposed the improvement plan. Dredging costal sediment distinguished the usage and the disposal by the Standard for the Beneficial Usage of Dredged Sediment. The site where disposal has been completed could be used as a site for developmental project. In case of the usage of dredged sediment for reclamation, we found that the adaptation of the Standard for Beneficial Usage of Dredged Sediment is appropriate for reclamation considering the characteristic of soil, the differences of variables, and the distinction of standard analysis methods. The current the Standard for Beneficial Usage of Dredged Sediment requires the improvement with the usage of dredging coastal sediment in the following. First, the Standard needs to include the standard of the discrimination for reclamation. Second, the current Standard is necessary to be divided by two levels, it needs to be mitigated considering human health risk. Third, it is necessary to consider both the marine environmental impact assessment and mitigation plan near coastal dredging area.

  • This study aims to assess the maturity of Korean open access (OA) journals using the OA infrastructure provided by the Korea Institute of Science and Technology Information, and develop necessary strategies for future improvement. The assessment model consists of three dimensions, 12 items, and 24 sub-items. The importance of the three dimensions (A: OA policy establishment and disclosure, B: OA sustainability, and C: Journal openness quality) was differentiated by the Analytic Hierarchy Process, and the maturity stages were divided into five levels (Entry, Growth1, Growth2, Maturity1, and Maturity2). The assessment was carried out twice for 100 academic journals. The results indicated that the proportion of journals at or above the Growth1 level increased by 11% to reach 83% during the second assessment phase, which could be owing to the learnings of the first assessment. Following expert consultations on the assessment results, three support measures were identified to activate OA. The first includes OA promotion and education activities, which involve creating standard regulations and guidelines, and advancing educational activities for societies that are either preparing for or currently implementing OA. The second involves providing support for technical aspects, such as identifiers, XMLization, and copyright management, through peer review and OA publishing platforms. The third includes collaborative activities to enhance journal evaluations and the recognition criteria for researchers' achievements in OA journals, and fostering cooperation with national and research and development institutions for financial support.

  • Professionalism, objectivity, and fairness are highly required in the assessment of tasks in national research and development projects. Experts in the technologies should thus focus on the task's plan in the review process. The same scores in the assessment, however, do not mean that the judges don't have the same opinions. Another problem is the possibility that different weights can be applied for evaluation indexes. This study proposed an AHP-based assessment criteria decision system for national research and development tasks to reduce errors in task assessment and selection and improve the professionalism and fairness by objectifying the evaluation criteria of each index. As a result, the assessment criteria were objectified for each index in the projects. In addition, the professionalism and fairness of experts were secured in the process of setting assessment criteria for each index based on the given marks of weights.
