  • This study focused on research that illustrates the important interplay between learners' epistemological beliefs about science knowledge, physics textbook knowledge and knowing physics in the classroom. Also this study investigated learners' conceptual changes on the value of mechanical energy. To explore these topics, six sophomores were chosen as participants. Three categories were introduced to classify how participants' understanding of the nature of science knowledge, physics textbook knowledge has been linked with epistemological beliefs of knowing physics. The three categories were (1)receiving physics knowledge as authority, (2)receiving physics knowledge as the perception of teacher's role and (3)understanding physics knowledge as the perception that science knowledge is a product of a variety of human ideas. These categories were also concerned with construction of individual conceptions of mechanical energy. The participants who understood physics knowledge as the perception that science knowledge is a product of a variety of human ideas naturally used metacognitive strategy in classroom compared to other participants. And they had scientific conceptions about the value of mechanical energy. Others who were passive in classroom had unscientific conceptions about the value of mechanical energy due to definition of energy and epistemological beliefs about the nature of science knowledge. In the process of their conceptual changes on the value of mechanical energy, it was important to understand an instrumental aspect of scientific knowledge and to think about the relation between formulae and physical phenomena.

  • Despite that Korea has tried 50 years of service development policies, the result has been unsatisfactory. Borrowing the policy stream model of policy change and narrative policy framework one tried to explain the weaknesses of the policy process for the service development policies. Before 2000 lacking knowledge resulted in poor policy narratives while after 2000 despite sufficient knowledge base and well articulated narratives policy window would not open. Adversarial politics under conservative party caused the window to be closed. One suggests that paradigm shift in value and world view treats is necessary to overcome the policy failures in service development policy. According these analyses one expects a new initiative of policy narrative construction.

  • The purpose of this study was to examine whether or not they have been revised corresponding to the purpose of revision by making a comparative analysis of the content and illustration in the 6th and 7th primary science textbooks. The analysis of content was composed of knowledge, inquiry process and attitude. The analysis of illustrations was composed of the kinds of illustrations and the role of illustrations. The findings of this research were as follows: First, as a result of content analysis of the primary science textbooks in the 6th and the 7th national curriculum, the ratio of inquiry process showed the highest frequency, next knowledge and lastly scientific attitude. And the 7th textbooks are greatly emphasized knowledge and science attitude. Second, as a results of the illustration analysis are as follows: There are conspicuous differences in that the illustration number of the 7th science textbooks Is about twice the illustration number of the 6th science textbooks and next, they place more weights on pictures and comics hard to discovery in the 6th science textbooks. Therefore, they have tried to induce the interests of students and heighten their understanding by supplementing the role of illustration presented as picture-centered and increasing its number presented as picture. In the results, although they have improved the problems of the 6th national curriculum a lot through the innovation including the interest induction of pupils through comics, the development of its content presentation method, the gradual change of subject number and the cultivation of curriculum according to the level of enrichment and supplementing types, the 7th science textbooks have fallen short of 6.3%, not around 30% in terms of the reduction in the 7th national curriculum. Accordingly, the 7th science textbooks also can be pointed out to have the problems of too much amount of studying compared to the time per week like the 6th science textbooks.

  • The evolution of information technology and proliferation of hospital management and managerial applications of computing has led to change in the characteristics, uses and evaluations of software for the hospital management. With the growing proliferation of microcomputer use and the value-added for management strategies, more and more software has been massively developed, produced and distributed for the hospital industry. The user is faced with an increasingly difficult choice in the evaluation and selection of software. For many reasons, users frequently must rely on expert evaluations of the technical functions and quality of software. The objectives of this study are to provide selection criteria for an Electronic Medical Record (EMR) and to develop an evaluation framework for the Hospital Information Systems. The major findings of our study are as follows (1) the identification of EMR evaluation characteristics (2) the design and development of EMR selection model and (3) the evaluation of the importance for EMR characteristics using Analytic Hierarchy Process (AHP). We identify 6 characteristics and 22 sub-characteristics of the EMR, calculate their weights, and decide the best configuration. Especially, the AHP methodology can be applied to gather knowledge from multiple experts. Because AHP can 1) facilitate the participation of multiple experts 2) increase group productivity and therefore result in both quantitatively and qualitatively superior outcomes than that of a single individual's work 3) provide a mechanism for reconciling conflict from multiple expert 4) validate the acquired knowledge, providing consistency of facts, and 5) enhance the accuracy reliability of the acquired knowledge increase through of the reliability provided by consensus across multiple experts. Although some further research is required, the proposed model can be regarded as a basis for the selection of EMR.

  • We modeled fish school movements as a capture process in relation to the purse seine method using the three steps of the stimulus-response process (i.e., input stimuli, central decision-making and output reaction). Input stimuli of the model were categorized as either physical stimuli such as visual stimulus, sound stimulus, water flow, and weather or as biological stimuli such as species and size, swimming performance, sensual sensitivity, and presence of prey or predators. The output process determining the spatial orientation of the fish school for 3-D movements was based on swimming speed and angular change in the fish response, and these movements were animated as the relative geometry between the fish school and the purse seine. Simulations were carried out for skipjack tuna (Katsuwonus pelamis) schools reacting to a pelagic purse seine in the southwest Pacific Ocean. Simulation results showed that escape ratios varied from 20 to 70% by the relevant ranges in the stimulus-response thresholds, swimming speeds, and angular changes of fish schools were similar to those observed in the field. Therefore, with knowledge of relevant parameters, this model can be used to predict capture and escape probabilities of purse seine operations for different fish species or conditions.

  • The goal of educating consumers regarding food safety is to increase consumer competency in food safety. In order to recognize consumer problems and to develop consumer competency in rapidly changing consumer environment, it is necessary to cultivate consumer knowledge, attitude, and ability on food safety required in performing the consumer role effectively. Within this context, it is necessary to develop consumer-oriented education programs which aim to change consumer values and behaviors with regard to food safety. Based on information obtained from focus group interviews, the need for educational programs for food safety, which are related to the whole process of food consumption, have been raised. The process of food consumption is divided into buying, cooking/eating, and after eating, based on the process of consumer decision making and consumer behavior. Scenarios for consumer education on food safety were developed depending on the process of food consumption. This study developed a pilot consumer education program which included the whole process of food consumption. The program of this study was designed to induce consumers to change their behavior through establishing values on food safety and may contribute to lay the foundation for the realization of food safety culture. The results will be utilized to provide future directions for consumer education programs and efficient educational materials on food safety. Finally, it is hoped that empirical evaluation and analysis on the effects of consumer education programs will be investigated in future studies.

  • Risk assessment is useful tool making good decisions on the risks of certain hazardous com-pound and suggests safe margin through scientific process using toxicological data, statistical tool, exposure value and relevant variants. The goal of risk management is to protect the public health from hazardous compound based on result of risk assessment having reality. For the suggestion of exact man-aging information, risk assessment must be designed to represent a "plausible estimate" of the exposure to the individuals and to minimize uncertainty. Risk assessment methodology and knowledge are expected to change more rapidly than before and up-to-date methodology should be applied in regulatory aspects through the Agency. For the useful application of risk assessment, the communication between the risk assessor and the risk manager is needed before the initiation of the risk assessment and upon its completion. Generally, the risk assessment itself as a practical tool in the regulatory decision making process would be regarded with social economic impact.ic impact.

  • The purpose of this study is to suggest some strategies for integrated science. It also suggests educational strategies through worldview. The directions of most educational policy are based on the deficit model. It is assumed that learners are always lacking in knowledge, and as a result they do not understand properly. However, it is difficult for the public and students to change their attitudes because they do not feel much lacking. For example, the world view of climate change coexists with an optimistic mechanical worldview and an organic and entropy worldview. This study is characterized by the process of expanding awareness of living and fulfillment of knowledge rather than the existing deprivation model. Unconnected knowledge has problems in diversity. It is neither sustainable nor flexible. It is not about eliminating interdisciplinarity but about lowering it. We go into another area with your deep expertise, but we must have a purpose. As a result, not only problem solving but also dynamic feedback of mutual feedback between other domains increases the quality and quantity of knowledge.
