This research uses descriptive and verification methods, in addition to that in this study using the counting method with Path Analysis and processed using the LISREL for Students program. The population in this study was unknown and took samples using an iterative technique which resulted in a sample of 115 respondents. In addition, data collection in this study was carried out by distributing questionnaires and interviewing respondents directly. This research is equipped with managerial implications that can be useful for the company / organization studied in this study to solve internal and external problems in the A-H Jaya Frozen Food Store environment. The results of this study indicate that the questionnaire distributed shows valid and reliable results and all processed variables show a significant effect. The value of t is greater than the value of t table, namely the value of the store atmosphere variable is 10.86> 1.65 and 6.29> 1.65, while simultaneously fcount is also greater than the table value, namely 7.51> 3.08. The effect of the store atmosphere shows a greater influence than the product price, which is 37.9%, while the product price variable has an effect of 12.9%. The effect of the two variables shows the effect of 53.4% and is a strong influence to influence consumer purchasing decisions. © 2021 Karadeniz Technical University.

Online educational engagement systems include all the activities of a learner like listening, reading, writing, and so on. While participating in these activities, a participant may show various levels of engagements like fully engaged, partially engaged and completely not engaged. The participation of online learners has to be identified for an effective learning process. The existing literature could be classified depending upon the learners’ participation as automatic, semi-automatic and manual. Further it could be sub categorised based on the data types used to identify the engagement system. In this paper, a review on computer based automatic online educational engagement detection systems is presented. Several educational engagement methods are applied for computer based online engagement detection systems. In these systems examining a participant’s presence and attention with the modalities of facial expression, eye movement and speech are found to be a challenging task. In this work, it is also identified that there are few challenges like preparation and usage of proper datasets, identifying suitable performance metrics for different tasks involved and providing recommendations for future enhancement of online educational engagement detection by combining the modalities of facial expression, eye movement and speech are still unattended. Though there are several research gaps involved, an online educational engagement system will help the learners to engage themselves in a productive way of learning and getting evaluated efficiently and effectively during the lockdown period of pandemic disease COVID-19 without interrupting their learning process and gaining knowledge. © 2021 Karadeniz Technical University.

The implication in critical discourse analyses is how this study raises the rules of language and linguistic practices that are implanted together with the relationship of a practice or social act that is often not realized by us so far. This study also criticizes the tendency of language studies to simply use linguistic rules and practices, as objects that are described, in a way that obscures their ideological and political inculcations. In this research, the authors examine the impact of the spread of the virus on the Indonesian economy, as well as the government's response to the public health crisis, as well as the efforts made to overcome the economic crisis that has arisen Covid -19 and 'new normal' based on the textual analysis of Jokowi's Speech.

This epidemic disease not only includes high mortality due to viral infection but also caused the psychological disaster in all parts of the world. The paper provides the early Coronavirus stage detection COVID-19, with the methods of machine learning. Support vector machine (SVM) is a two-class classifier which in the recent years attracted a significant attention. The performance of this classifier depends on the amount of its parameters such as C (Penalty Factor) and the existing parameter in kernel. Also the selection of a suitable kernel function has a significant affect in its performance improvement. Besides the mentioned cases, performing the feature selection process not only causes to improve the mentioned performance improvement but also causes to reduce the computation complexity and training time. In this paper, we used the improved partial swarm optimization algorithm (IPSO) to optimize the SVM. Findings illustrated that proposed method could be utilized for diagnosing disease of COVID-19 as the assistant system. Promisingly, the proposed method can be regarded as a useful clinical decision tool for the physicians. © 2021 Karadeniz Technical University.
