  • This study was to investigate the relationships between stress coping strategies, emotion regulation ability and behavior problems with children from low-income families and middle-income families. Subjects were 171 children from low-income families and 228 children from middle-income families, 4th - 6th grade in elementary school. The major findings are followings: (1) The level of emotion regulation ability in children from low-income families was lower and active stress coping strategies were less than children from middle-income families. In the behavior problem, children from low-income families were higher than children from middle-income families. (2) The stress coping strategies(active/ social support) in children from low-income families were related with internal behavior problem(anxiety /withdrawal). And the emotion regulation ability was related to the children's behavior problem. (3) Regression analysis model showed that emotion-regulation ability was the most influential factor to the children's behavior problem, and children from low-income families with aggressive coping strategy showed hyperactive behavior problem. So, the education/therapy programs for children from low-income families have to be developed and practiced in schools, local children centers and so on.

  • According to the current research of educational assessment, formative assessment which focuses on improving students' learning has been emphasized. Consequently, integration between instruction and assessment is crucial and various assessment strategies are required. In order to use different assessment strategies in classrooms, teachers should experience strategies and reflect their strengths and weaknesses. In this study, pre-service elementary teachers experienced six assessment strategies (feedback, providing assessment standard, providing exemplary cases, self assessment, peer assessment, and written assessment), and their perceptions toward each strategy were investigated. During one semester, pre-service teachers experienced each of them and they answered questionnaire at the end of the semester. From the results, it is found that pre-service teachers presented different strategies that were most helpful in their cognitive and affective domain according to their perception of assessment. The results imply that different assessment strategies should be applied in instruction and teachers should extend their perception of assessment purposes.

  • Although providing universal coverage for health care through the National Health Insurance(NHI) is a remarkable achievement, the issue of limited benefit coverage of the NHI has been at the core of national debate over how to improve its coverage. This study aims to evaluate benefit extension strategies and implemented policies with regard to the NHI since 1989 using 'policy window theory' proposed by John W. Kingdon. Understanding problem stream, policy stream, political stream, and coupling streams regarding the NHI, in particular benefit extension, would contribute to broaden policy debates and to develop more effective strategies for the future. Historically, political stream had opened policy window in the past two decades and policy streams can be characterized by three waves. Three streams have been coupled since 2003 and the government had a strong will to fulfill better performance of NHI coverage. Study findings indicate that identification of problem structure regarding NHI benefit was not connected with policy stream tightly. In addition, there has been limited discussion on policy goal and principles for extension coverage of the NHI. Policy strategies to improve coverage of the NHI should be linked to characteristics of problem and sought solutions under the principle which is expected to be sustainable through consensus in the society.

  • The purpose of this study was to examine the effects of metastrategic exercise on a scientific reasoning strategy to control variables, and investigate the developmental patterns in the strategy usage within a given period. Two groups composed of 90 fifth grade students engaged in a scientific reasoning task over six daily sessions. Additionally, one group engaged in metastrategic exercise on fictional students' strategies of controlling variables on the task, while the other spent equivalent time on an unrelated task. Based upon results of the study, the following conclusions can be drawn. First, the metacognitive exercise on the strategy to control variables has positive and long-standing effects on the strategy performance at the reasoning task. The exercise also takes effect of near-transfer. Taking into consideration only about sixty minutes of metastrategic practice, the results provide the validity of the activity in order to develop children's reasoning strategies. Second, in a scientific reasoning task, each child seems to go through one out of two developmental patterns in their usage of reasoning strategies: gradual change or fundamental change. Considering the ratio of pattern of fundamental change between the two groups, it is clear that the metacognitive exercise influences the developmental pattern of strategy usage.

  • An impeller is a type of high-speed rotor that is used to compress or transfer fluid under high-speed and pressure at high temperatures. The impeller is composed of an axial hub and several blades attached along the hub. The weight and shape of an impeller must be balanced, because their imbalances can cause noise and vibration, which can lead to the breakage of the impeller blades during operation. Thus, the hub and blades of an impeller are commonly machined in a 5-axis NC machine to obtain qualified surfaces. The impeller machining strategy or process plan can not be easily obtained due to the complex, overlapped and twisted shapes of impeller blades. Skillful machining process planners may generate appropriate machining strategies based on their experiences and floor data. However, in practice most shop floor data for the impeller machining is not well-structured such that it does not effectively provide a process planner with information for machining strategies and/or process plans. This paper reports the development of a case-based machining strategy support system (CBMS) that employs case-based reasoning to obtain the machining strategy of an impeller by using the existing machining strategies of the shop floor. The CBMS generates impeller machining strategies through a stepwise reasoning process considering the similarity features between the blade shapes and machining regions. A case study is provided to demonstrate that CBMS can generate useful machining strategies facilitating process planners. The developed system can simulate the tool paths of impeller machining and runs on the web.

  • Air pollution is a global challenge that not only threatens public health, but also takes away lives. Strategic communication, in other words, public relations, is an essential way of tackling air pollution and managing the risks involved. Engaging global citizens into the public sphere requires the building of a sense of collectivity and duty on achieving clean air. Strategies and policies on an international scale that are based on the theoretical framework (Behavior Procedure Model) and focus on leading citizens into the mature and unified Collectivity during the observance of the 'International Day of Clean Air for blue skies' are crucial. Notably, the Asian continent has inevitably found itself at the crossroad between economic growth and environmental protection, and has even been observed to be pursuing a passive response to air pollution. The key communication strategies are supported by the three goals, which include: expanding existing communities and building a new Collectivity, supporting international solidarity and individual member state activities, and implementing systems and structures. The key goals can be further specified into six strategies. This paper has analyzed global problems and discussed possible communication strategies to increase public engagement for the observation of the 'International Day of Clean Air for blue skies.' It will be the responsibility of all nations to implement the aforementioned strategies and policies as well as promoting global action.

  • In the light of the strategic utilization of the national R & D projects, this paper is to induce the spin-off strategies to improve the national R & D effectiveness through analyzing the spin-off characteristics of nuclear technologies, the spin-off status of the advanced countries and the case study of Korean nuclear spin-offs. Spin-off process is viewed as a three-stage operation, such as preparation stage, implementation stage and maintenance stage. In order to find the correlation between the influencing factors and spin-off effectiveness, the Spearman's correlation coefficient was employed as a specific statistical technique. By integrating this correlation, spin-off process and spin-off strategies, this paper presents an efficient framework to improve the spin-off effectiveness.

  • The limited durability of resin-dentin bonds severely compromises the longevity of composite resin restorations. Resin-dentin bond degradation might occur via degradation of water-rich and resin sparse collagen matrices by host-derived matrix metalloproteinases (MMPs). This review article provides overview of current knowledge of the role of MMPs in dentin matrix degradation and four experimental strategies for extending the longevity of resin-dentin bonds. They include: (1) the use of broadspectrum inhibitors of MMPs, (2) the use of cross-linking agents for silencing the activities of MMPs, (3) ethanol wet-bonding with hydrophobic resin, (4) biomimetic remineralization of water-filled collagen matrix. A combination of these strategies will be able to overcome the limitations in resin-dentin adhesion.

  • Objectives: The purpose of the study was to develop communication strategies for effective nutrition education targeting pregnant women and to create nutrition education contents. Methods: The format and the contents of online resources on nutrition information for pregnant women provided by reliable institutions were analyzed. Possible solutions to overcome barriers of nutrition education as well as communication strategies for effective nutrition education were identified by a brainstorming process. Based on the communication strategies, contents for nutrition education were created. Understandability, level of interest, applicability to daily life, harmony of text and illustration, and overall satisfaction of the contents were evaluated by dietitians and pregnant women. Results: The four communication strategies were developed; (1) to focus on a few important messages, (2) to provide evidence-based information, (3) to create illustrations or infographics with a minimum amount of text, and (4) to provide tips on how to improve the current diet options. Based on these strategies, the contents were focused on three important nutrients for pregnant women, folate, iron, and calcium. The percentages of the recommended nutrient intakes of the three nutrients on selected menu and its improved version by adding a dish or changing a dish into another dish were calculated and provided. Finally, the contents were delivered as illustrations with a minimum amount of text. Overall, dietitians and pregnant women were satisfied with the contents. Conclusions: The contents developed in this study can be used in a pamphlet or a pregnancy diary, or can be shared in social networking services. Further contents on other nutrients and various menu are expected to be developed using these communication strategies.

  • This study investigated the influences of metacognitive learning strategies upon 6th-graders' achievement, science process skill, use of cognitive strategies, use of metacognitive strategies, self-efficacy, intrinsic value, attitude toward science class, and scientific attitude. The metacognitive learning strategies were developed on the basis of previous results and modified in a pilot study. Before the instructions, a pretest of motivation was administered, and used as a blocking variable. The score of previous achievement test was used as covariates for achievement and science process skill. Tests of use of cognitive strategies, use of metacognitive strategies, self-efficacy, intrinsic value, attitude toward science class, and scientific attitude were also administered, and their scores were used as covariates. After the instructions, a researcher-made achievement test, the Middle Grades Integrated Science Process Skills Test, and post-tests of above variables were administrated. Two-way ANCOVA results revealed that the scores of the treatment group were significantly higher than those of the control group for all tests except for science process skill. No interactions between the treatment and the level of the previous motivation were found. Educational implications are discussed.
