This study aimed to investigate how science teachers perceived major features of the 2007 revised science curriculum and implementing them in classes. The 2007 revised science curriculum included critical features such as creativity, open inquiry, science writing, discussion and STS. In terms of necessity, clarity and complexity of those features for curriculum implementation, teacher perceptions were examined. Particularly with regard to open inquiry assigned 6 class periods per semester as one of the critical features of 2007 revised science curriculum, we asked teachers how they would prepare and implement the technique in their teaching. In results of this study, science teachers agreed on the necessity and importance of those major features of the 2007 revised science curriculum, including creativity, open inquiry, science writing, discussion, and STS. However, they were not clear on how those would work in their classrooms and expected various impediments. Open inquiry was specifically perceived as most negative in its implementation with the mention of various complex reasons. Based on findings in this study, we proposed the 'Dual Action Research Model' for curriculum implementation. It tries to explain how curriculum is implemented in classrooms and diminish the gaps between curriculum developers and teacher users by means of leading teachers to understand the curriculum meaningfully and implement their teaching based on this understanding.

This study investigated the effects of national science leading school programs on students' positive experiences about science (PES) and teachers' perceptions of curriculum implementation factors affecting students' PES. For this study, Test for Indicators of Positive Experiences about Science (TIPES) was administered to a total of 11,488 students from 117 national science leading schools and 1,315 students from 50 normal counterpart schools. In addition, a total of 105 teachers were given a survey asking their curriculum implementation levels and perceptions on importance and performance levels of each identified factor that was known to influence students' PES. Students' total PES scores and scores in five sub-components of PES were widely varied across science leading school program types. In general, participating teachers reported common curriculum implementation factors that most positively affected students' PES including 'science-related activities out of school,' 'student-centered research projects,' 'ICT-related materials' and 'performance assessment.' Based on these results, implications for science education were discussed.

As the information needs in civil society is getting diverse, the interest in local policy process based on the characteristics of local communities, especially in local policy implementation is growing. However, research in library and information policy has focused rather on policy alternatives than policy process in Korea. In this study, we analyze the policy implementation in "the First Library in my Life" policy in Kyeonggi province with the framework of the Street-Level Bureaucracy Model by Michael Lipsky. In the analysis, we attempt to identify factors in the policy implementation, to examine the usefulness of the model into the situation of Korean library policy, and to suggest major considerations in the policy implementation in Korean public libraries for successful policy implementation. From the results, the usefulness of the model is examined and the need of considering indirect socio-economic factors is suggested.

The relevance of the study implies the need to explain the main determinants of environmental policy, allowing countries to converge on a common working basis. The purpose of the research is to explore ways in which the environmental aspects of EU regions and territories can be shaped to apply to domestic environmental policy. A total of 997 representatives from the Ukrainian UTCs, who are involved in local environmental policy, participated in the survey. Results of the research. A hierarchy of regional environmental policy objectives has been identified. Three key principles of eco-policy development have been distinguished. The means of the innovative approach strategy implementation have been outlined (formation of the regional market of environmental services; organization of interaction between environmental agencies and market structures; establishment of environmental funds which finance environmental activities; implementation of the "collateral return" system; formation of a system of benefits and loans to enterprises that successfully implement the environmental policy). The means of the prognostic approach implementation strategy to the development of the region's environmental policy have been determined (the use of an orderly and successful long-term strategy of economic development of the region; obligatory consideration in the mechanisms strategy aimed at improvement of environmental management system of the region, interbranch impact of the projects implemented on the region's ecological situation; taking into consideration the economic and geographical peculiarities of the region, the necessary infrastructure, issues of the territorial location of the large enterprises in the region and their impact on the environment). The means of the traditional approach strategy implementation have been outlined (activity programs focused on solution of specific problems, rather than on the implementation of measures for environmental restoration and enhancement; nature conservation problems have interbranch, interdepartmental character due to unity of the region's ecosystem; tracking complexity of changing conditions (water basins, woodlands, air-mass transport), regional boundaries generally do not coincide with natural ecosystems boundaries). The practical significance of the study lies in providing recommendations for the implementation of certain aspects of Ukrainian UTC's environmental policy.

Background: The purpose of this study is to investigate the pro-con of re-implementation by administrative areas and the difference in perception of community water fluoridation in implemented and non-implemented areas after the community water fluoridation in Korea was suspended. Through this, we intend to provide basic data that can help find ways to increase the support and interest of local residents. Methods: The 601 questionnaires collected through the survey and statistical analysis was conducted using SPSS Statistics 28.0. Results: As a result of analyzing the perception of the community water fluoridation according to the understanding of fluorine, the proportion of people who were not recognized by both fluorine and community water fluoridation was the highest (p<0.05). As a result of the analysis of the pro-con of re-implementation of community water fluoridation, the approval was high. Among those who responded in favor, the place of re-implementation showed that 'implementation nationwide' was high. As for the reason for favor, it was found that it was possible to prevent dental caries disease. The reason for the objection was the lack of knowledge about fluoride. Conclusion: The results of the survey for the pro-con of the re-implementation of community water fluoridation showed a higher degree of 'agree' and showed that people in the area where community water fluoridation was not implemented showed higher interest in oral health prevention and management. Through this, not only oral education, but also correct information on the implementation method of community water fluoridation, the benefits of community water fluoridation, and the facts that were misunderstood in the past, as well as oral education, can be provided to raise interest in community water fluoridation. It is thought that the expected effect of the re-implementation of community water fluoridation can be obtained if such activities are carried out.

This study explored changes of preservice biology teachers' pedagogical knowledge and science teaching efficacy belief after the science pedagogy course. Preservice biology teachers who did not take any science pedagogy courses had an opportunity to engage in discussions of educational theories and group activities of instructional design utilizing science instructional models as a first step to develop practical knowledge. These preservice teachers represented a statistically significant increase in their scores on pedagogical knowledge including theory, student development, planning, and implementation, but no statistical difference in their scores measuring science teaching efficacy belief. In addition, the correlation results indicated that the science teaching efficacy belief is related to implementation even though the magnitude is relatively moderate.

Ultrasonic melt treatment (UST) was applied to an A390 hypereutectic Al-Si alloy in a temperature range of $750-800^{\circ}C$ and its influence on the solidification structure and the consequent increase in strength was investigated. UST at such a high temperature, which is about $100^{\circ}C$ above the liquidus temperature, had little effect on the grain refinement but enhanced the homogeneity of the microstructure with the uniform distribution of constituent phases (e.g. primary Si, ${\alpha}-Al$ and intermetallics) significantly refined. With the microstructural homogeneity, quantitative analysis confirmed that UST was found to suppress the formation of Cu-bearing phases, i.e., $Q-Al_5Cu_2Mg_8Si_6$, $Al_2Cu$ phases that form in the final stage of solidification while notably increasing the average Cu contents in the matrix from 1.29 to 2.06 wt%. A tensile test exhibits an increase in the yield strength of the as-cast alloy from 185 to 208 MPa, which is mainly associated with the solute increment within the matrix. The important role of UST in the microstructure evolution during solidification is discussed and the mechanism covering the microstructure-strengthening interrelationship of the ultrasonically treated A390 alloy is proposed.

This study aims at investigating the effects of digital accounting implementation on audit performance of tax auditors in Thailand through audit competency and audit report as the consequence. In addition, it examines the effects of audit learning, digital culture, and stakeholder expectation on digital accounting implementation. The key informants were Thailand's tax auditors. The data was collected using a questionnaire that was distributed to 349 tax auditors throughout Thailand. The response rate was 20.53%. The Ordinary Least Squares (OLS) is applied to test the research relationships. The results of this study show that digital accounting implementation has an important effect on its consequence, namely audit competency, audit report, and audit performance. Similarly, audit competency and audit report affect audit performance. Testing the antecedents of the research relationships, namely audit learning, digital culture, and stakeholder expectation, the result reveals that only digital culture affects digital accounting implementation. Accordingly, digital accounting implementation plays a vital role to enhance audit competency, audit report, and ultimately lead to attaining audit performance. Furthermore, the results are beneficial for the auditing practitioners and regulators, allowing them to draw on these results to develop training programs to enhance professional audit efficiency.

An approach to efficient implementation of real-time control systems is presented in this paper. A compiler for translation of control algorithms is used in combination with a general program for real-time control. The compiler translates control algorithms written for the simulation in a design language to an implementation language. The translated algorithms are then automatically incorporated in the real-time control program.

Titanium carbide (TiC) powders are successfully synthesized by carburization of titanium hydride ($TiH_2$) powders. The $TiH_2$ powders with size lower than $45{\mu}m$ (-325 Mesh) are optimally produced by the hydrogenation process, and are mixed with graphite powder by ball milling. The mixtures are then heat-treated in an Ar atmosphere at $800-1200^{\circ}C$ for carburization to occur. It has been experimentally and thermodynamically determined that the de-hydrogenation, "$TiH_2=Ti+H_2$", and carburization, "Ti + C = TiC", occur simultaneously over the reaction temperature range. The unreacted graphite content (free carbon) in each product is precisely measured by acid dissolution and by the filtering method, and it is possible to conclude that the maximal carbon stoichiometry of $TiC_{0.94}$ is accomplished at $1200^{\circ}C$.
