This paper provides a series of new results in both steady-state accuracy and frequency-domain analyses for two Laguerre-based approximators to the Grünwald-Letnikov difference. In a comparative study, the Laguerre-based approximators are found superior to the classical Tustin- and Al-Alaoui-based approximators, which is illustrated in simulation examples.

BACKGROUND Since November 2019, Covid - 19 has spread across the globe costing people their lives and countries their economic stability. The world has become more interconnected over the past few decades owing to globalisation and such pandemics as the Covid -19 are cons of that. This paper attempts to gain deeper understanding into the correlation between globalisation and pandemics. It is a descriptive analysis on how one of the factors that was responsible for the spread of this virus on a global scale is globalisation. OBJECTIVE - To understand the close relationship that globalisation and pandemics share. - To understand the scale of the spread of viruses on a global scale though a comparison between SARS and Covid -19. - To understand the sale of globalisation present during SARS and Covid - 19. METHODS A descriptive qualitative comparative analysis was used throughout this research. RESULTS Globalisation does play a significant role in the spread of pandemics on a global level. CONCLUSIONS - SARS and Covid - 19 were varied in terms of severity and spread. - The scale of globalisation was different during the time of SARS and Covid - 19. - Globalisation can be the reason for the faster spread in Pandemics.

This study examines why and how Chinese characters spread into Korea. It subsequently conducts a comparative analysis of Korean and Chinese children’s textbooks with a focus on Yu Hap from the perspective of the acceptance and acculturation of Chinese characters. It also explores how commonly used the characters in Yu Hap are, and the text’s learning value as one of Korea’s children’s textbooks. Yu Hap is very significant as the first written language textbook published in Korea. A comparative analysis of the characters used in four children’s books published in Korea found that the characters in Yu Hap are very common, and the text has a high learning value. Approximately 50% of the characters in San Bai Qian and Yu Hap are the same, showing that both China and Korea had similar perceptions of the characters in common use. A very significant proportion of characters overlap in Basic Chinese Character for Educational Use, List of Common Words in Modern Chinese, and Yu Hap; this supports the idea that the same characters have continued to be used from ancient times to the present day.

Since recently almost all housing built in Korean have shared walls and floor, diverse problems are unavoidable including noise between floor arising from noise and vibration. Many efforts have been made by the Korean government, but the number of complaints related with the noise between floors has been gradually increasing. Therefore, through the field measurements by house type, the current state of noise was understood. To do this, the noise between floors was measured in an apartment household and a multiplex house to perform a comparative analysis. As the result, the differences in the noise between the two house types were clarified. The findings of this research are expected to contribute to reduction of the noise between floors in an apartment building in the future.
