The purpose of this qualitative case study was to investigate the 'structure' of an elementary school teacher's practical knowledge concerning science experiment lessons. A female elementary teacher in the early career years participated in the study, and video recordings of her science experiment lessons as well as audio-taped interviews with her were analyzed by means of Elbaz's framework. The teacher expressed six images of science experiment lessons: 'Science is difficult', 'Experiments are dangerous', 'Experiments are accurate', 'A science experiment takes a long time', 'Science experiments are interesting', and 'Children are little scientists.' These images were supported by several principles and rules, most of which were clearly described. Among the images, principles, and rules, there were complex relationships with some working in synergy and some conflicting. In case of the image 'Children are little scientists', its subordinate principles and rules were not fully realized in the classroom. Implications for science teaching reform and science education research were discussed.

The purpose of this study was to explore the status of 'Gesamtschule' (eng. Comprehensive school) in Germany and to suggest future direction for Korean education. To achieve this purpose, this study explored 1)the background of adopting Gesamtschule and its developing process; 2)Change of school structure since 2000 and the status of Gesmatschule. Results of this study indicated that 1)Changing school structure in Germany focused on closing educational gap caused by social class differentials; 2)Gesamtschule and other school model, similar with Gesamtschule are spreading widely in relation to change of school structure in secondary education; 3)Expanding this school model contributed to closing educational gap by analysing of recent results of PISA. This study suggested that efforts for closing educational gab in korean school should not only concentrate on supporting students, but also accompany discussion about change of school structure.

The recent global financial crisis has been the outcome of, among other things, the mismatch between institutions and the reality of the market in the current global financial system. The International financial institutions (IFIs) that were designed more than 60 years ago can no longer effectively meet the challenges posed by the current global economy. While the global financial market has become integrated like a single market, there is no international lender of last resort or global regulatory body. There also has been a rapid shift in the weight of economic power. The share of the Group of 7 (G7) countries in global gross domestic product (GDP) fell and the share of emerging market economies increased rapidly. Therefore, the tasks facing us today are: (i) to reform the IFIs -mandate, resources, management, and governance structure; (ii) to reform the system such as the international monetary system (IMS), and regulatory framework of the global financial system; and (iii) to reform global economic governance. The main focus of this paper will be the IMS reform and the role of the Group of Twenty (G20) summit meetings. The current IMS problems can be summarized as follows. First, the demand for foreign reserve accumulation has been increasing despite the movement from fixed exchange rate regimes to floating rate regimes some 40 years ago. Second, this increasing demand for foreign reserves has been concentrated in US dollar assets, especially public securities. Third, as the IMS relies too heavily on the supply of currency issued by a center country (the US), it gives an exorbitant privilege to this country, which can issue Treasury bills at the lowest possible interest rate in the international capital market. Fourth, as a related problem, the global financial system depends too heavily on the center country's ability to maintain the stability of the value of its currency and strength of its own financial system. Fifth, international capital flows have been distorted in the current IMS, from EMEs and developing countries where the productivity of capital investment is higher, to advanced economies, especially the US, where the return to capital investment is lower. Given these problems, there have been various proposals to reform the current IMS. They can be grouped into two: demand-side and supply-side reform. The key in the former is how to reduce the widespread strong demand for foreign reserve holdings among EMEs. There have been several proposals to reduce the self-insurance motivation. They include third-party insurance and the expansion of the opportunity to borrow from a global and regional reserve pool, or access to global lender of last resort (or something similar). However, the first option would be too costly. That leads us to the second option - building a stronger globalfinancial safety net. Discussions on supply-side reform of the IMS focus on how to diversify the supply of international reserve currency. The proposals include moving to a multiple currency system; increased allocation and wider use of special drawing rights (SDR); and creating a new global reserve currency. A key question is whether diversification should be encouraged among suitable existing currencies, or if it should be sought more with global reserve assets, acting as a complement or even substitute to existing ones. Each proposal has its pros and cons; they also face trade-offs between desirability and political feasibility. The transition would require close collaboration among the major players. This should include efforts at the least to strengthen policy coordination and collaboration among the major economies, and to reform the IMF to make it a more effective institution for bilateral and multilateral surveillance and as an international lender of last resort. The success on both fronts depends heavily on global economic governance reform and the role of the G20. The challenge is how to make the G20 effective. Without institutional innovations within the G20, there is a high risk that its summits will follow the path of previous summit meetings, such as G7/G8.

In March 2021, the <Guidance on Promoting the Scientific Interface between Kindergarten and Elementary School> issued by the Ministry of Education of China clearly pointed out that it is necessary to adhere to child oriented. This goal of this policy is based on the idea of "living education" proposed by Mr. Heqin Chen in 1940, which indicates that a true understanding of children is necessary before talking about educating them. The core goal of "bidirectional articulation" is to strengthen the sense of articulation between kindergartens and elementary school, scientifically prepare for and adapt to school enrollment, and promote the smooth transition of children. Moreover, the <Guidance Points for Kindergarten Readiness Education> and the <Guidance Points for Elementary School Adaptation Education>, which were released at the same time as the <Guidance on Promoting the Scientific Interface between Kindergarten and Elementary School>, also place special emphasis on the cultivation of children's life preparation and adaptability. The aim of the bidirectional articulation "bridging" is to realize a two-way exchange of curriculum between kindergarten and elementary school, and to reform the curriculum at three levels through the curriculum spirit of "gamification", the continuous curriculum structure, and the developmental curriculum evaluation.

The battlefield environment of the Korean peninsula is rapidly changing due to the advancement of the weapon system brought by the political situation of adjacent countries and the 4th industrial revolution. The reduction of population also caused a sharp drop in the recruitment of military personnel, making it unavoidable to reform the military structure. This meaningful study is timely with recent news reports on the shortage of recruitment by 10,000 persons in the last five years. Universities are also seeing a decrease in the number of new students due to the reduced school-age population, and affiliated universities are responding to this issue with great seriousness. With a reduction in manpower, requirement-handling military units need to step up their efforts to secure competent noncommissioned officers while affiliated universities must also train capable noncommissioned officers. As a solution to the matter at hand, this study aims to suggest a method that may vitalize both the navy and the navy-affiliated universities based on the results of literature research.

The purpose of this article is to examine the cause of policy non-compliance in the case of pharmaceutical rebates from the perspective of rational choice institutionalism. In Korea, there have been rebates practices between pharmaceutical companies and hospitals since the introduction of the Actual Remuneration System for insured medicine in 1999. The government has chosen the policy means of punishment to eliminate pharmaceutical rebates but the illegal practices are still widespread. Institution in rational choice institutionalism usually reflects the incentives and preferences of actors, and the Actual Remuneration System has resulted in a the lack of procedures to ensure savings on drug expenditures. Pharmaceutical rebates are the product of the institutions which reflect their incentives: the Actual Remuneration System, the current pricing policy for generic drugs, the drug distribution system, and so on. In the end, the problem of the rebates is the consequence of policy non-compliance as actors' rational choice because their incentives lead to opportunistic behaviors. We should therefore understand the incentive structure of policy stakeholders, which is derived from the view of new institutionalism; also, the newly designed Korean drug pricing policy reform must be compatible with the incentive structure.

The incorporation of nanoplatelets in composite and polymeric materials represents a recent and innovative approach, holding substantial promise for diverse property enhancements. This study focuses on the application of nanocomposites in the production of sports equipment, particularly soccer balls, aiming to bridge the gap between theoretical advancements and practical implications. Addressing the longstanding challenge of suboptimal interaction between carbon nanofillers and epoxy resin in epoxy composites, this research pioneers inventive solutions. Furthermore, the investigation extends into unexplored territory, examining the integration of glass fiber/epoxy composites with nanoparticles. The incorporation of nanomaterials, specifically expanded graphite and graphene, at a concentration of 25.0% by weight in both the epoxy structure and the composite with glass fibers demonstrates a marked increase in impact resistance compared to their nanomaterial-free counterparts. The research transcends laboratory experiments to explore the practical applications of nanocomposites in the design and production of sports equipment, with a particular emphasis on soccer balls. Analytical techniques such as infrared spectroscopy and scanning electron microscopy are employed to scrutinize the surface chemical structure and morphology of the epoxy nanocomposites. Additionally, an in-depth examination of the thermal, mechanical, viscoelastic, and conductive properties of these materials is conducted. Noteworthy findings include the efficacy of surface modification of carbon nanotubes in preventing accumulation and enhancing their distribution within the epoxy matrix. This optimization results in improved interfacial interactions, heightened thermal stability, superior mechanical properties, and enhanced electrical conductivity in the nanocomposite.
