Purpose – The purpose of this paper is to analyze airport efficiency using the DEA methodology as airport activities are an important factor to support economic activities and environmental issues. Design/Methodology/Approach – Based on the DEA methodology, traditional analysis including BCC, CCR, and Super Efficiency analysis have been utilized to analyze the trends of efficiency in economic indexes. The Malmquist Analysis results also show productivity changes before and after COVID-19. This paper conducted research on the efficiency of the Korean airports in operational and environmental aspects. Adopting DEA models, seven variables were selected for analysis. Findings – This paper found that efficient airports are mainly supported by their large business markets, better hinterland connectivity, being a major airport, and effective resource management. Also, comparing the overall productivity of Korean Airports from 2018-2020, it is fair to say that from 2018 to 2019, before COVID-19, internal factors were driving the overall productivity change. Following other airports, Yeosu were successful in enhancing the efficiencies of the internal operation of airports in the 2020 period. It is also notable that, during COVID-19, the level of cargo at Incheon International Airport, and skyrocketed passenger movements at Jeju International Airport affected the level of efficiency. After COVID-19, although internal efficiency was apparently evident as a decisive factor for overall productivity for most airports, some airports (Jeju, Pohang, and Yangyang) focused on external factors such as technology, which was driving the overall productivity change in their operation compared to others in the sample in this study. Research Implications – This study implies that COVID-19effects on global trade have changed the way airports operate, as most airports now focus on and invest in safety instruments as well as cargo support services and auxiliary services. Airports will confront an enormous task in the coming years, and these goals are ideologically compatible with sustainable development goals. Airports are here to endorse sustainable development, as well as facilitate possibilities and connectivity, and the disclosure of ESG business information are the appropriate resource to help expansion and improvement.

Rapid exchange and hydrolysis of the tubulin-bound guanine nucleotides have been known to govern the dynamics of microtubules. However, the instability and low concentration have made it difficult for the microtubule-bound GTP to be observed directly. In this study, we circumvent these problems by lyophilization and using cross-polarization techniques. $^{31}P$ NMR signals were detected from the tubulin-bound GTP in microtubules for the first time. Analysis of the $^{31}P$ CPMAS NMR spectrum indicates that GTP hydrolysis was delayed by the presence of taxol.
Bangladesh Politics: Confrontation, Monopoly and Crisis in Governance
Ferdous Arfina Osman 서울대학교행정대학원 2010 Asian Journal of Political Science Vol.18 No.3
Despite the restoration of parliamentary democracy in Bangladesh since 1991, politicalgovernance of the country is still mired by innumerable ills. It broadly features a widearray of confrontation, competition, monopolization of state institutions and resources bythe party in power. This trend of politics has tremendously weakened the formalaccountability mechanisms and put governance in crisis. This article depicts the nature ofconfrontational politics in Bangladesh, its causes and impacts on governance withsupportive evidence from both primary and secondary sources. As case examples, it showshow bureaucracy and local government institutions are grossly politicized as a result ofconfrontational politics and their impact on governance.

Streptomyces coelicolor is a gram-positive soil bacterium which is well known for the production of several antibiotics used in various biotechnological applications. But numerous proteins from its genome are considered hypothetical proteins. Therefore, the present study aimed to reveal the functions of a hypothetical protein from the genome of S. coelicolor. Several bioinformatics tools were employed to predict the structure and function of this protein. Sequence similarity was searched through the available bioinformatics databases to find out the homologous protein. The secondary and tertiary structure were predicted and further validated with quality assessment tools. Furthermore, the active site and the interacting proteins were also explored with the utilization of CASTp and STRING server. The hypothetical protein showed the important biological activity having with two functional domain including POD-like_MBL-fold and rhodanese homology domain. The functional annotation exposed that the selected hypothetical protein could show the hydrolase activity. Furthermore, protein-protein interactions of selected hypothetical protein revealed several functional partners those have the significant role for the bacterial survival. At last, the current study depicts that the annotated hypothetical protein is linked with hydrolase activity which might be of great interest to the further research in bacterial genetics.
Antinociceptive activity of the ethanolic extract of Ficus racemosa Lin. (Moraceae)

The ethanolic extract of Ficus racemosa Lin. (Moraceae) bark and fruit were tested for its possible antinociceptive activity study on acetic acid induced writhing method in mice. Both the bark and fruit extracts at a dose of 500 mg/kg body weight showed significant antinociceptive activity on the experimental animals. The fruit extract showed most potent inhibition of acetic acid induced writhing in mice (61.38%, P < 0.001) where as the bark extract showed inhibition only 42.6% (P < 0.001) and all the result were statistically significant.
