Background: Engaging and Involving stakeholders who have different interests in changing health care policies are difficult task. As the literature on the governance in Korean health care field is rare, this study aims to provide empirical evidence of 'governing health policy'-the ways health care policy is made, implemented, and evaluated from a political perspective. Methods: The authors of this study conducted interviews with elites in policy and clinical areas, which was considered to be the most effective approach to gather in-depth information about the background of changing payment policy as well as the barriers or contributors for making the policy sustainable. A total of 14 experts (3 government officials, 2 representatives from medical profession, 3 professors form academic field, and 6 healthcare providers from New DRG pilot program hospitals) participated in 2 hour long interviews. Results: There was a perception gap of the feasibility and substantiality of new payment system among elites. The score was higher in government officers than those in scholars or clinical experts. Next, the interviewees indicated that Korean New DRG might not sustain without significant efforts to improving democratic aspects of the governance. It is also notable that all interviewees except healthcare providers provided negative expectation of the contribution of new payment system to increase administration efficiency. For clinical efficiency, every stakeholders perceived there was no increased efficiency after introduction of New DRG payment. Like general perception, there was a wide gap between the perception of stakeholders in quality change after implementing the new payment system. Finally, interview participants negatively assumed about the likelihood of New DRG to remain a case of successful reforms. Conclusion: This study implied the importance of social consensus and the governance of health policy.

For accurately analysing and forecasting the social networks of China's political, economic and social power elites, it is necessary to develop a database that collates their information. The development of such a database involves three stages: data definition, data collection and data quality maintenance. The present study recommends distinctive solutions in overcoming the challenges that occur in existing comparable databases. We used organizational and event factors to identify the Chinese power elites to be included in the database, and used their memberships, social relations and interactions in combination with flows data collection methodologies to determine the associations between them. The system can be used to determine the optimal relationship path (i.e., the shortest path) to reach a target elite and to identify of the most important power elite in a social network (e.g., degree, closeness and eigenvector centrality) or a community (e.g., a clique or a cluster). We have used three social network analysis tools (i.e., R, UCINET and NetMiner) in order to find the important nodes in the network. We compared the results of centrality rankings of each tool. We found that all three tools are providing slightly different results of centrality. This is because different tools use different algorithms and even within the same tool there are various libraries which provide the same functionality (i.e., ggraph, igraph and sna in R that provide the different function to calculate centrality). As there are chances that the results may not be the same (i.e. centrality rankings indicating the most important nodes can be varied), we recommend a comparison test using different tools to get accurate results.

This study examines and identified a series of strategies of Russia's political elites to maintain and strengthen their dominance by reviewing the case of revisions in the election laws of Russia in 2014. At that time, a mixed-member electoral system was newly introduced, and on the surface, it seemed that the new system was a step toward meeting the demands of the people for "enhanced democracy". However, in 2016 and 2021, the ruling party of Russia won the general elections by making the most of the factors that could distort the election results inherent in the mixed-member electoral system. Therefore, this study aimed to analyze whether the revision of election laws was a mere vehicle used by the ruling party, United Russia, to maintain its political power, or whether it was a leap forward to achieve democracy. The study result indicate that the revision of election laws in 2014 was part of the policy responses to the internal conflicts in the circle of Russia's political elites, which had been rising since 2008, as well as to the public resistance. In other words, it was confirmed that the revision of election laws was one of the measures taken to "minimize competition" and "reproduce political power on a stable basis".

In recent years, geopolymer cements, have gained significant attention as an environmental-friendly type of cement. In this experimental research, effects of different alkaline activator solutions and variations of associated parameters, including time of addition, concentration, and weight ratio, on the mechanical strengths of Granulated Ground Blast Furnace Slag (GGBFS)-based Geopolymer Concrete (GPC) were investigated. Investigation of the effects of simultaneous usage of KOH and NaOH solutions on the tensile and flexural strengths of GGBFS-based GPC, and the influence of NaOH solution addition time delay on the mechanical strengths is among the novel aspects investigated in this research. four series of mix designs and corresponding specimen testing is conducted to study different parameters of the active alkali solutions on GPC mechanical strengths. The results showed that addition of NaOH to the mix after 3 min of mixing KOH and Na2SiO3 with dry components (1/3 of the total mixing duration) resulted in the highest compressive, tensile and flexural strengths amongst other cases. Moreover, increasing the KOH concentration up to 12 M resulted in the highest compressive strength, while weight ratio of 1.5 for Na2SiO3/KOH was the optimum value to achieve highest compressive strengths.

This article addresses the roles of the speech language pathologist (SLP) for singers who require prompt and effective treatment when a voice problem arises. The causes of voice problem are often vocal abuse/misuse/overuse, muscle tension dysphonia and inappropriate singing technique. The SLP should conduct voice counseling and voice assessment for maintaining healthy voice of singer constantly.

This paper concerns two new analytical approaches for solving high nonlinear vibration equations. Energy Balance method and Hamiltonian Approach are presented and successfully applied for nonlinear vibration equations. In these approaches, there is no need to use small parameters to solve and only with one iteration, high accurate results are reached. Numerical procedures are also presented to compare the results of analytical and numerical ones. It has been established that, the proposed approaches are in good agreement with numerical solutions.

Much effort has been made to measure regional difference showing the pattern of regionalism in Korea. Focusing the concept of social distance, this paper examines various election and regional preference data. The paper presets three major findings. First current election data show clear regional cleavage. Second, regional discrimination and prejudice is often found in one' s everyday life. Third, political aspect of regionalism is strongly related to social aspect of regionalism. These findings suggest that regionalism in Korea will survive for the time being. The regionalism is rooted in everyday life. To political elites, it became an attractive and economic way to maintain their power. This tendency will promote the preference for parliamentary system among political elites and the possibility of appearance of regional party.

This paper proposes a method improving the convergence speed of optimal solution for parallel genetic algorithm in the network based client-server model. Unlike the existing methods of obtaining global elite only by evaluating local elites in server, the proposed method obtains it by evaluating local elites and improving its fitness by applying genetic algorithm during idle time of the server. By using the improved chromosome in server for the client's genetic algorithm processing, the convergence speed of the optimal solution is increased. The improvement of fitness at the server during the interval of chromosome migration is (equation omitted)(F$_{max}$(g)-F$_{max}$(g-1)), whole F$_{max}$(g) is a max fitness of the g-th generation and G is the number of improved generation by the server. As the number of clients increases and G decreases, the improvement of fitness goes down. However the improvement of fitness is better than existing methods..
