In this study, explicit Teaching and Learning strategy for middle school students were developed to improve basic science process skills. After applying these strategy in an actual class, the effects of Teaching and Learning strategy and change of students were analyzed. Explicit Teaching and Learning strategy to improve basic science process skills are developed based on analyzing preceding research. The use of application criteria for class of basic science process skills combined with explicit Teaching and Learning strategy, it is sought for the explicit instructional procedures of said skills. After analyzing the class in which explicit Teaching and Learning strategy were demonstrated, students reported that they were able to comprehend basic science process skills more effectively through the stages of explicit explaining and independent practice. The showing demonstration stage was heavily emphasized by the teacher in this class. Analysis of students' understanding degree about basic science process skills, most of them show positive outcome. Another analysis of ripple effect on daily life and other subjects, it is found that students could have the attitude to make use of science process skills for themselves. Through the result of study, it is found that explicit Teaching and Learning strategy that are developed from this study are an effective way to comprehension students' basic science process skills. Thus, continued study is needed to develop and spread explicit Teaching and Learning strategy of science process skills to be applicable in actual classes in secondary schools.

The purpose of this study is to investigate the development of scientific conceptual understanding through a process-centered assessment that visualizes the process of scientific argumentation. In this study, 353 high school students and five teachers participated in the scientific argumentation. As a result of analyzing students' utterances on the elements of argumentation, scientific concepts in intragroup were embodied through query and clarification of meaning, and organized through agreement and rebuttal. In intergroup argumentation, scientific concepts were elaborated through query, clarification of meaning, and change of claim. Teachers were able to understand the process of argumentation through small-group activity sheets where the process was visualized, thereby providing feedback and improving the class. Based on the results, the scientific argumentation of visualizing the process was found not only to allow students to perform self-assessment and peer-assessment but also to help teachers understand the argumentation process. The findings of this study guide process-centered assessment in the science curriculum and are expected to contribute to the promotion of scientific argumentation in classrooms.

As a method of countermeasure to bed degradation and armoring phenomena of bed material in the downstream area of dam reservoirs, sediment augmentation (replenished sediment) has been carried out in many Japanese rivers. In general, bed of the replenished sediment site is composed of rocks, because the site is located in the downstream area of the dams and sediment supply is very small. Bed deformation process has been researched by many researchers. As a method of countermeasure to bed degradation and armoring phenomena of bed material in the downstream area of dam reservoirs, sediment augmentation (replenished sediment) has been carried out in many Japanese rivers. In general, bed of the replenished sediment site is composed of rocks, because the site is located in the downstream area of the dams and sediment supply is very small. Bed deformation process has been researched by many researchers. However, most of them can treat movable bed only and cannot be applied to the bed deformation process of sediment on rocks. If the friction angle between the sediment and the bed surface is assumed to be the same as the friction angle between the sediment and the sediment, sediment transport rate must be smaller without sediment deposition layer on the rocks. As a result, the reproduced bed geometry is affected very well. In this study, non-equilibrium transport process of non-cohesive sediment on rigid bed is introduced into the horizontal two dimensional bed deformation model and the model is applied to the erosion process of replenished sediment on rock in the Nakagawa, Japan. Here, the Japanese largest scale sediment augmentation has been performed in the Nakagawa. The results show that the amounts of the eroded sediment and the remained sediment reproduced by the developed numerical model are $56300m^3$ and $26800m^3$, respectively. On the other hand, the amounts of the eroded sediment and the remained sediment measured in the field after the floods are $56600m^3$ and $26500m^3$, respectively. The difference between the model and field data is very small. Furthermore, the bed geometry of the replenished sediment after the floods reproduced by the developed model has a good agreement with the measured bed geometry after the floods. These results indicate that the developed model is able to simulate the erosion process of replenished sediment on rocks very well. Furthermore, the erosion speed of the replenished sediment during the decreasing process of the water discharge is faster than that during the increasing process of the water discharge. The replenished sediment is eroded well, when the top of the replenished sediment is covered by the water. In general, water surface level is kept to be high during the decreasing process of the discharge during floods, because water surface level at the downstream end is high. Hence, it is considered that the high water surface level during the decreasing process of the water discharge affects on the fast erosion of the replenished sediment.

This study looked at the concretizing process of the Free Semester Policy(as is the FSP). The concretizing process of policy refers to the process in which the major components of policy idea are changing through the agenda setting and policy decision process. To this end, we collected major policy documents related to the FSP from the pledge of the presidential candidate to the implementation plan of the FSP and the oral data of key personnel of the FSP, and analyzed the concretizing process of the policy focusing on the policy objectives. As a result, it was found that the policy objectives of the FSP were presented in a more comprehensive and ambiguous form through the agenda setting and policy decision process. The emphasized direction of policy has also changed over and over. This phenomenon offers several implications for understanding education policy. First, it should be understood that the objectives of education policy presented at a specific point in time are provisional. Second, the change in policy objectives may have occurred in the process of securing the legitimacy of policy promotion. Third, it is necessary to pay more attention to the relationship between policy and politics. In order to properly promote an education policy based on the common sense and needs of the public, a mature education policy discussion culture is required.

This study identifies the current status of hanok design process and required design information through individual survey and interview with hanok architects and builders to suggest a proposal. Current design system turns out to be a common design process not reflecting hanok's unique mechanism of production. The proposal consists of the alternative design process, 'Initial survey / Site and structural planning / Spatial layout and form / Openings, interior and exterior elements design / Detail design', containing the specialty of hanok's mechanism, and the lists of design information required in its each stage. The proposed design process also emphasizes the significance of consultation in a way of designing coordination, and classifies the specific contents for each consultation moments. The study is expected to contribute for architects including the group who are not specialized in hanok to improve the architectural quality by following the systematic design process. Also the design system provides a framework to organize the vast range of design information being recently developed in the technique-oriented area.

The study examines the effect of environmental factors on the international harmonization process of accounting on small and medium enterprises in Vietnam. These factors include legal environment, business environment, and cultural environment. The data is collected by a survey of 100 accountants and 100 auditors on the factors that affects the international harmonization process of accounting. The T-Tests indicate differences between the answers of the accountants and auditors. First, for the accountants, legal environment has the biggest effect on the harmonization process of accounting; while on the auditors, business environment has the biggest influence. Second, while the accountants consider costs higher than benefits in the harmonization process of accounting, the auditors assume that benefits are superior to costs that businesses spend. Third, both the accountants and the auditors indicate that the harmonization process of accounting should not be applied for all small and medium enterprises. From the study results, the author has given a different evaluation method that Vietnam should implement for international harmonization with the required adjustments as per the suitability with the status of businesses in Vietnam. The process of harmonization in accounting practices should not be indiscriminately applied to all the small and medium enterprises either.

Magnesium alloys have many advantages such as light-weight, high machinability, damping capacity, etc. So magnesium alloy parts have been used in transportation, mobile phone, military industries. Because of HCP atomic structure, Magnesium is very difficult in plastic deformation process, so most of magnesium products are fabricated by casting process. Magnesium alloys have low heat-capacity, high fluidity and low Fe solubility. For these reasons it is more suitable than aluminum in mass-production by casting. And various casting technologies have been developed. So casting technologies for magnesium developed recently is discussed in this paper.
