Shifting Meme Content during Information Development on the COVID-19 Pandemic in Indonesia
Kadri Kadri,Jumrah Jumrah 한국과학기술정보연구원 2022 Journal of Information Science Theory and Practice Vol.10 No.1
This research aims to identify and reveal the meaning of memes about COVID-19, and explain changes in meme content in regard to the information development of COVID-19 in Indonesia published by the mass media and online media. The data is sourced from memes that are shared on social media, especially WhatsApp groups in the period of January to June 2020. To reveal the meaning of memes, a semiotic analysis of Roland Barthes’ model is used. Qualitative analysis is used to reveal the relationship between memes and the information development of COVID-19 in Indonesia. The results of the study show that meme content has shifted according to three stages of information development of COVID-19 in Indonesia published by the mass media and online media. When COVID-19 was not yet confirmed in Indonesia, meme content contained mostly humor that was not educative, moreover it seemed to underestimate the coronavirus. Meme content which is mostly humorous and pornographic occurred when COVID-19 was confirmed in Indonesia and during the lockdown policy. At last, as the government has begun to distribute social assistance, the meme content looks more critical. The results of this research emphasize the urgency of the mass media as a source of public information during the COVID-19 pandemic, become a reference for the community in making memes as a forum for expressing feelings and social criticism, and serve as a reference for the government to act and make the right decisions related to the pandemic that is endemic in their country.
A FOURTH-ORDER ACCURATE FINITE DIFFERENCE SCHEME FOR THE EXTENDED-FISHER-KOLMOGOROV EQUATION
Kadri, Tlili,Omrani, Khaled Korean Mathematical Society 2018 대한수학회보 Vol.55 No.1
In this paper, a nonlinear high-order difference scheme is proposed to solve the Extended-Fisher-Kolmogorov equation. The existence, uniqueness of difference solution and priori estimates are obtained. Furthermore, the convergence of the difference scheme is proved by utilizing the energy method to be of fourth-order in space and second-order in time in the discrete $L^{\infty}-norm$. Some numerical examples are given in order to validate the theoretical results.
MERIDIAN SURFACES IN E4 WITH POINTWISE 1-TYPE GAUSS MAP
Kadri Arslan,Betul Bulca,Velichka Milousheva 대한수학회 2014 대한수학회보 Vol.51 No.3
In the present article we study a special class of surfaces in the four-dimensional Euclidean space, which are one-parameter systems of meridians of the standard rotational hypersurface. They are called meridian surfaces. We show that a meridian surface has a harmonic Gauss map if and only if it is part of a plane. Further, we give necessary and sufficient conditions for a meridian surface to have pointwise 1-type Gauss map and find all meridian surfaces with pointwise 1-type Gauss map.
Contact CR-Warped Product Submanifolds in Kenmotsu Space Forms
Kadri Arslan 대한수학회 2005 대한수학회지 Vol.42 No.5
Recently, Chen studied warped products which are CR-submanifoldsin Kaehler manifolds and established general sharp inequalities for CR%-warped products in Kaehler manifolds. In the present paper, weobtain sharp estimates for the squared norm of the secondfundamental form (an extrinsic invariant) in terms of the warpingfunction for contact CR-warped products isometrically immersedin Kenmotsu space forms. The equality case is considered. Some applications are derived.
ON GENERALIZED ROTATIONAL SURFACES IN EUCLIDEAN SPACES
Kadri ARSLAN,Betul Bulca,Didem Kosova 대한수학회 2017 대한수학회지 Vol.54 No.3
In the present study we consider the generalized rotational surfaces in Euclidean spaces. Firstly, we consider generalized tractrices in Euclidean $ (n+1)$-space $\mathbb{E}^{n+1}$. Further, we introduce some kind of generalized rotational surfaces in Euclidean spaces $\mathbb{E}^{3}$ and $ \mathbb{E}^{4}$, respectively. We have also obtained some basic properties of generalized rotational surfaces in $\mathbb{E}^{4}$ and some results of their curvatures. Finally, we give some examples of generalized Beltrami surfaces in $\mathbb{E}^{3}$ and $\mathbb{E}^{4}$, respectively.
