The Dominance of Organizational Culture towards the Effectiveness of System Based on Islamic Values
Статья научная
Organizational culture is the dominant value or habit that becomes the driving force for an organization. Values, thoughts, and symbols based on Islam that influence the norms of behavior, attitudes, habits, and habits of a person in various fields become the culture of Islamic organizations that are believed to be true. The fundamental problem in this research is that organizations do not understand what the dominant organizational culture is today, how effective the system users are with these cultural conditions, and whether the current level of effectiveness of the dominant culture follows Islamic values. Previous research shows the relationship between organizational culture and effectiveness, while this study adds new variables, and proves the relationship of organizational culture dominance model with system effectiveness based on Islamic values on practical contribution, and creates a new model on theoretical contribution. The research phase begins with finding the current dominant organizational culture using the Organizational Culture Assessment Instrument and the Cultural Values Framework Instrument. Next, look for the relationship between the current dominant organizational culture and the effectiveness of the system by using the Delone and Mclean Is Success Model. Then combine the second model based on Islamic values using Structural Equation Modeling (SEM) - Partial least square (PLS). The result of this research is that there is a relationship between the dominance of the current organizational culture and the effectiveness of information systems. This is because the dominant organization is a clan that is familial in reaching an agreement, commitment between members in communicating, increasing the intensity of members in using information systems, systems that are easy to reach and use, and the quality of information systems that are easy, effective, and accountable. Meanwhile, the dominance of organizational culture on the effectiveness of information systems based on Islamic values has not been fully proven. This means that the dominance of organizational culture on the effectiveness of the Islamic values information system still needs to be adjusted to the four indicators on the Islamic values variable showing the closeness of values.

eGovernment application has evolved from simply appearing as a website providing news and information, to the application that provides various services through online transactions. Provision of online transactions require the effectively and safely service, so the users can make sure that the entry data is secure and will not be used by other parties which are not authorized. Security is also necessary for the service provider side of online transactions, it is necessary to keep the system, and the data transactions sent through the communications media and the data stored in the database are secured. If the security guarantee is unavailable, the users will gradually lose their confidence to use the service through online transactions by using eGovernment application, and on the other hand the service provider will face the impact of the lost or corrupt data, and unauthorized access to the data which should be only accessed by involved parties based on the appropriate authority. This paper reveals the proposed strategy of Pretty Good Privacy implementation in protecting the security data messages of the Official Scripts Electronic Applications in a Local Government Regency.

The Philosophy of Smart Learning Using the Approach Thomas Kuhn Paradigm Shift
Статья научная
The impact of technology must be addressed by the educational methods themselves and their perspectives in the new paradigm of citizenship in this intelligent environment. Learning environments have changed dramatically in the last 50 years, in large part due to information and communications technologies. The study uses a qualitative descriptive. Thomas S. Kuhn, fully Thomas Samuel Kuhn, (born 18 July 1922 in Cincinnati, Ohio, USA-17 June 1996 in Cambridge, Massachusetts), best known for The Structure of the Scientific. Kuhn explains that in every scientific discipline, there are some identified and natural phenomena that are then investigated experimentally and explained theoretically. Pre-paradigm as the basis of normal science, the formation of smart learning is started when primitive cave. Normal science for learning is a traditional teaching method, teaching takes place within the four walls of a classroom. Anomalies are surprising discoveries that cannot be defined through a paradigm, together with discoveries of troubles that cannot be solved through a paradigm. The lock down following the COVID-19 pandemic has made us extrude in a single day from mastering withinside the bodily international to mastering withinside the virtual one. Model crises are the third phase of the Kuhn cycle. Triggering the Model Crisis movement Blended learning can be the brand new normal – “Blended learning”. The smart learning cognizance and traits has emerged as a brand-new fashion withinside the international academic field. different smart technologies, consisting of cloud computing, learning analytics, huge information, Internet of things (IoT) and wearable generation.

Keyword extraction approaches based on directed graph representation of text mostly use word positions in the sentences. A preceding word points to a succeeding word or vice versa in a window of N consecutive words in the text. The accuracy of this approach is dependent on the number of active voice and passive voice sentences in the given text. Edge direction can only be applied by considering the entire text as a single unit leaving no importance for the sentences in the document. Otherwise words at the initial or ending positions in each sentence will get less connections/recommendations. In this paper we propose a directed graph representation technique (Thematic text graph) in which weighted edges are drawn between the words based on the theme of the document. Keyword weights are identified from the Thematic text graph using an existing centrality measure and the resulting weights are used for computing the importance of sentences in the document. Experiments conducted on the benchmark data sets SemEval-2010 and DUC 2002 data sets shown that the proposed keyword weighting model is effective and facilitates an improvement in the quality of system generated extractive summaries.

Theory of Fuzzy Sets: An Overview
Статья научная
In this article, we would like to revisit and comment on the definition of complementation of fuzzy sets and also on some of the theories and formulas associated with this. Furthermore, the existing probability-possibility consistency principles are also revisited and related results are viewed from the standpoint of the Randomness-Fuzziness consistency principles. It is found that the existing definition of complementation as well as the probability – possibility consistency principles is not well defined. Consequently the results obtained from these would be inappropriate from our standpoints. Hence we would like to suggest some new definitions for some of the terms often used in the theory of fuzzy sets whenever possible.

Time-Frequency Wavelet Based Coherence Analysis of EEG in EC and EO during Resting State
Статья научная
The electrophysiological brain activities are nonlinear in nature as measured by Electroencephalography (EEG). There are coherent activities in brain not only seen during explicit tasks but also during rest. This article aims to employ most robust nonlinear dynamics Time - Frequency representation (TFR) techniques such as wavelet phase coherence to investigate brain activity in different frequency bands at temporal and spatial scale dynamics in form of topographic maps in resting state networks. The TFR has the advantages to study the combined effect of time and frequency domains simultaneously. The wavelet coherence computed in this way exhibit high precision to detect the phase coherence in different frequency intervals to analyze highly complex non-autonomous and non-stationary EEG signals. The spatiotemporal dynamics of resting state networks are investigated by computing coherence. We have investigated the Wavelet based Phase coherence of oscillations of eye closed and eye open signals during resting states. The wavelet coherence is computed for selected 19 electrodes according to 10-20 system from 129 channel EEG signals. The significance was obtained using Wilcoxon Signed Rank test and pairwise wavelet coherence was computed for each possible combination. The Wavelet Phase Coherence using Wavelet Transform gives significantly high results (P<0.05) in EC and EO signals during resting states in frequency interval 0.5-50 Hz overall as well as in the band intervals such as delta (05-4 Hz), theta (4-7 Hz), alpha (7-13 Hz), beta (13-22 Hz) and gamma (22-50 Hz). By computing the spatial wavelet phase coherence, we observed significant pathways including sagittal factor (anterior-posterior interhemispheric) and lateral factor (perpendicular to anterior-posterior axis). The lateral factor differences have less affect than the sagittal factor. Each band was involved in different activities in some way, however alpha band showed distinct anterior-posterior activity when the eye-closed coherence was higher than the eye open coherence.

Top-k Closed Sequential Graph Pattern Mining
Статья научная
Graphs have become increasingly important in modeling structures with broad applications like Chemical informatics, Bioinformatics, Web page retrieval and World Wide Web. Frequent graph pattern mining plays an important role in many data mining tasks to find interesting patterns from graph databases. Among different graph patterns, frequent substructures are the very basic patterns that can be discovered in a collection of graphs. We extended the problem of mining frequent subgraph patterns to the problem of mining sequential patterns in a graph database. In this paper, we introduce the concept of Sequential Graph-Pattern Mining and proposed two novel algorithms SFG(Sequential Frequent Graph Pattern Mining) and TCSFG(Top-k Closed Sequential Frequent Graph Pattern Mining). SFG generates all the frequent sequences from the graph database, whereas TCSFG generates top-k frequent closed sequences. We have applied these algorithms on synthetic graph database and generated top-k frequent graph sequences.
