  • National R&D programs play an important role in the development of a country in this age of the knowledge economy. Since many numbers of R&D programs compete for limited resources such as national R&D budget, the R&D program evaluation problem is a challenging decision-making problem faced by decision makers that deal with R&D management. In this sense, DEA(Data Envelopment Analysis) has been regarded as one of the most widely accepted methods to measure the relative efficiency of productivity of R&D programs. DEA is a methodology to measure and to evaluate the relative efficiency of a homogeneous set of decision-making units(DMUs) in a process which uses multiple inputs to produce multiple outputs. However, the sample of the R&D programs could consist of two or more naturally occurring subsets, thus exhibiting clear signs of heterogeneity such as different objectives. In such situations, the fairness of DEA is limited, for the nature of the relative efficiency of a DMU is likely to be influenced by its membership in a particular subset of the sample. In this study, we propose a methodology AI-DEA(attainment index DEA) allowing for reflecting decision maker's subjective judgement on difference among different subsets of R&D programs which have heterogeneous objectives. This methodology combines AHP and Delphi in order to decide the attainmnet index of each DMU for each outputs, and apply them to DEA model. We illustrate the proposed approach with a pilot evaluation of 13 programs involving 6 different subsets of Korean National R&D programs and compares the results of the original DEA model and AI-DEA model.

  • The primary purpose of this study was to assess understanding of concrete and formal operational science content by concrete and formal operational students in secondary school physical science classes. To carry out this study subjects were selected from junior high schools of over 2500 students, and they were identified as concrete, transitional, or formal operational using GALT(Group Assessment of Logical Thinking) developed by Roadrangka, Yeany and Padilla(1983). Instructional objectives were extracted from the science content taught during the second term of the academic year in the 7th, 8th and 9th grade, and they were classified as concrete or formal operational. Written test involving those objectives were constructed and administered. The results of this study suggested that formal operational thought brought deeper understanding to concrete science content as well as formal science content. Differential effects by sex on understanding of both concrete and formal science content were contradictory through the grade levels. Results of multiple comparison tests suggested that students categorized as formal operational demonstrated no better understanding of concrete science content than those categorized as transitional. However, they demonstrated better understanding of formal science content.

  • The purpose of this study was to evaluate the propriety of various aspects of the 7th home economics science curriculum in high school. In this study, home economics education experts participated in a three-round Delphi survey. The findings of this study were as follows: First, the experts evaluated that the subject arrangement and title 'home economics science' were inadequate. Second, the experts evaluated that the characteristics of home economics science were similar to those in prior home economics curricula, and that the characteristics of the subject were also ambiguous. Third, the experts evaluated that the objectives of home economics science were too technically presented, and pointed out that the objectives are not distinct from those of prior home economics courses as they are too general and abstract. Fourth, the experts evaluated that the content of home economics science was deficient in its hierarchy and integration. Moreover, the contents do not sufficiently reflect the characters of the learners or their social demands. Fifth, the experts evaluated that the teaching/learning methods of home economics science were stated for the sake of formality only. Even though it provides many methods, it is not practical in the current educational situation. Sixth, the experts evaluated that although home economics science provides various methods of assessment, it has practical difficulties under current educational circumstances. Besides, the assessment methods failed to give concrete and objective standards.

  • Portfolio assessment provides many opportunities to foster children's creativity and to increase their responsibility for learning. few research study has been conducted in this area, and this assessment method has scarcely been administered in primary science class, Proper and effective use of portfolio assessment in our primary science class requires basic research on how to design and administer the method. Based on the earlier study on typical structures and components of portfolio assessment, the assessment instrument was developed on various primary science topics, The development team was consisted of one science education specialist and nine pre-service elementary school teachers. It takes ten months to develop instruments for 27 class hours. The development process was reciprocal in that development and revision cycle was repeated more than 7 times. The portfolio assessment instruments consist of instructional objectives, developers' evidence for the objectives, and assessment criteria. Adopting a new way of assessment into science class inevitably causes lots of confusions to teachers and children. The absence of basic research studies must be a critical barrier for successful administration of a new assessment method such as portfolio assessment. further research is required in the preparation and administration of portfolio assessment in our primary science classroom.

  • The purpose of this study is to propose learning objectives in social dental hygiene by analyzing and reviewing learning objectives in oral health administration area of the existing public oral health. This study is a cross-sectional study. The subjects of the study selected with convenience extraction were 15 members of the social dental hygiene subcommittee of the Korean Society of Dental Hygiene Science. Data collection was conducted by self-filling questionnaire. The research tool is from 48 items of A division in the book of learning objectives in the dental hygienist national examination, and this study classified each of them into 'dental hygiene job relevance', 'dental hygiene competency relevance', 'timeliness', and 'value discrimination of educational goal setting' to comprise 192 items. Also, to collect expert opinions, this study conducted Delphi survey on 7 academic experts. Statistical analysis was performed using the IBM SPSS Statistics ver. 23.0 program (IBM Co., Armonk, NY, USA). Recoding was performed according to the degree of relevance of each learning objective and frequency analysis was performed. This study removed 18 items from the whole learning objectives in the dental hygienist national examination in the oral health administration area of public oral health. Fifteen revisions were made and 15 existing learning objectives were maintained. Forty-five learning objectives were proposed as new social dental hygiene learning objectives. The topics of learning objectives are divided into social security and medical assistance, oral health care system, oral health administration, and oral health policy. As a result of this study, it was necessary to construct the learning objectives of social dental hygiene in response to changing situation at the time. The contents of education should be revised in order of revision of learning objectives, development of competency, development of learning materials, and national examination.

  • We present guaranteed dynamic priority assignment schemes for multiple real-time tasks subject to (m, k)-firm deadlines. The proposed schemes have two scheduling objectives: providing a bounded probability of missing (m, k)-firm constraints and maximizing the probability of deadline satisfactions. The second scheduling objective is especially necessary in order to provide the best quality of service as well as to satisfy the minimum requirements expressed by (m, k)-firm deadlines. We analytically establish that the proposed schemes provide a guarantee on the bounded probability of missing (m, k)-firm constraints. Experimental studies validate our analytical results and confirm the effectiveness and superiority of the proposed schemes with regard to their scheduling objectives.

  • In this study, domains, contents, and effects of pre-existed intervention programs for individuals with arthritis were meta-analyzed to develop arthritis health promotion program based on Holistic Model. The developed program includes strategies of cognition, environment, and behavior. and also generates positive changes in the physical, psychological, and social demensions. Then needs assessment on conveniently selected 153 women who visited a university hospital in Seoul or in Inchon are conducted to identify the objective domains of arthritis health promotion program According to the study results. target health problems of the arthritis health promotion program were shown as pain, disability, depression, and role impediment in social domain. These objectives could be achieved by including the strategies of changing cognition, the strategies of changing behavior through learning the skill related to the health promoting behavior. and the strategies of changing environment in the health promotion program. That is, it is analyzed that the contents of program are not exclusive one another in physical. psychological. and social demensions, and also are not exclusive one another in aspect of cognition, behavior, and environment. The necessary methods to achieve the desired objectives for the developed arthritis health promotion program and evaluation subjects are as follows : (1) In the arthritis health promotion program, knowledge on management of arthritis, efficacy related to arthritis management, skill for pain management, skill for exercise, establishment of positive self-concept, enhancement of positive thinking, stress management. skill for problem solving, skill for setting goals. skill for requesting help, and skill for communication are all included. Through the improvement of all those strategies, intermediate objectives, such as “joint protection, and maintenance of pain management behavior”, “maintenance of regular exercise”, and “promotion of coping skill in psychosocial dimension” are achieved. (2) These intermediate objectives are also the methods for achieving objectives in next stage. It implies that through the intermediate objectives. the final objectives such as “minimization of physical symptoms and signs”, “maximization of psychological function”, and “maximazation of role performance in social domain” could be achieved. Each of these final objectives reflects the different dimension of quality of life, respectively. When these objectives are achieved, the quality of life that client perceives is improved. Therefore, through evaluation of these final objectives, the level of achieving final outcome of arthritis health promotion such as quality of life is determined.

  • This study analyzed the learning objectives in the 2007 revised 10th grade Home Economics textbooks of 6 different publishing companies and the achievement standards developed by Ministry of Education, Science and Technology(2009). Two experienced coders performed initial analysis based on the 'revision of Bloom's taxonomy of educational objectives' and had subsequent conferences to reach an agreement on different results between coders. For knowledge dimension, the results show that the major types of learning objectives in the "Future Family Life" unit are mainly consisted of factual knowledge and procedural knowledge, where as those of "Family Life Culture" unit are consisted of factual knowledge and conceptual knowledge. The achievement standards in both "Future Family Life" and "Family Life Culture" units are solely in a factual knowledge major type. The sub-type of knowledge dimension of both learning objectives and achievement standards fall into 'a specific facts and knowledge component'. For cognitive process dimension, the results show that the leaning objectives are focused on 'understand' and 'analyze'. Those of achievement standards are 'analyse' in the "Future Family Life" unit and 'understand' in the "Family Life Culture" units. From the result of this study, we can conclude that both learning objectives and achievement standards do not adapt any meta-cognitive knowledge, higher order thinking, and cognitive process.
