The Effect of Distance Learning on the Kanji Reading Ability of 4th Semester Students

Distance learning that works during the covid-19 pandemic changed the student's ability to receive or understand the learning content. Kanji is one of the difficult lecture materials for Japanese language students. A very large number of kanji letters and students' study habits are only made before a test becomes an obstacle in mastering kanji, so persistence, interest, and motivation are needed to learn kanji during distance learning. The preliminary study results show that students' motivation and interest decreased during distance learning. This study aims to determine whether there is an effect of distance learning on the ability to read kanji in fourth-semester students. The instrument used was a questionnaire distributed online with 47 students of Japanese Language Education class 2019 involved as respondents. The study results show that distance learning affects students' kanji reading skills by 22.4%. A student's ability to read kanji is influenced by external and internal factors, including a lack of support from friends and family during the study from home, lack of interest in learning kanji during distance learning, lack of time to practice and learn kanji every day, and students still tend to learn kanji only when there is an exam
Efficacy of Pleurotus eryngii Mycelium Containers as an Alternative to Current Single-Use Plastic Based Methods

Introduction: The COVID-19 pandemic has led to an increase in takeout orders due to the mandated loss of dine-in options at restaurants. The significant rise in takeout has led to the use of single-use plastic containers that are currently made from materials such as polyethylene and expanded polystyrene (EPS). The aim of our research is to determine the effectiveness of Pleurotus eryngii (King oyster mushroom) based mycelium in replacing single-use takeout food containers. Methods: Variables such as flexural strength, permeability, insulation test, interactions between food and mycelium container, and decomposability in comparison to the common EPS takeout container. Various articles from scholarly sources such as PubMed, Google Scholar, and Omni library were used to determine the anticipated results. Results (hypothesized): The flexural strength test will be greater than or equal to 0.43 mPa. The mycelium container should be able to stop various viscosities of food from diffusing through the container due to the hydrophobicity of the mycelia. The mycelium should have greater insulation capacity than the standard EPS container. Qualitative observations obtained for interactions between the mycelium container and food should be similar to the control EPS container. Discussion: The mycelium container will be an effective alternative to using single-use EPS containers due to all tested variables resulting in the same or greater capabilities than the EPS container. Conclusion: Overall, using mycelium containers as an alternative to single use plastic takeout containers would reduce plastic waste and emission pollution, having a positive impact on climate change.

Human Face Identification Using Haar Cascade Classifier and LBPH Based on Lighting Intensity

The problem in implementing online learning during the Covid-19 era is the lack of internet access for video streaming, especially in small towns or villages. The solution idea is to minimize the video bandwidth quota by only showing emoticons. The first step of the process is the system must be able to lock the face area to be translated. This study aims to identify areas of the human face based on camera captures. The research was conducted using the Haar cascade classifier algorithm to recognize the facial area of the captured image. Then the Local Binary Pattern Histogram algorithm will recognize the identity of the face. The lighting scenario will be used as a distracting effect on the image. The results showed that based on 30 sets of images tested in bright conditions, the system was able to recognize facial identities up to 62%, normal conditions 51% and dark conditions 46%.
Sentiment Analysis of Expedition Customer Satisfaction using BiGRU and BiLSTM

The occurrence of a pandemic caused behavioral changes that occurred in Indonesian society, especially in increasing interest in online purchases. The increased purchases of goods increased the volume of four expeditions, namely: JNE, JNT Express, Sicepat, and Anteraja. To find out the customer satisfaction of the users of the four expeditions automatically, sentiment analysis was conducted based on the thousand tweet data from the opinions of expedition users in three-class categories, which are positive, negative, and neutral. Two deep learning methods were used to analyze the sentiment of expedition customer satisfaction: BiGRU and BiLSTM. The activities conducted during the sentiment analysis were crawling, preprocessing, data labeling, modeling, and evaluation. The performance evaluation results of the two methods use an accuracy matrix over 1,217 test data. The BiGRU method produces an accuracy performance of 71.5% and the BiLSTM method produces an accuracy performance of 66.5%.

The results also found: The internal cognitive load and germane load can predict the cognitive failure of university students, where the beta value reached the level of statistical significance at the level of 0.05. The external cognitive load did not reach the level of statistical significance in its ability to predict cognitive failure among university students. By adding the internal and external cognitive load in one degree and re-predicting again, the results showed that the value of beta -0.586 has reached the level of statistical significance at 0.05. There are no statistically significant differences between males and females in cognitive load and cognitive failure according two variables (gender and specialization).
Peculiarities of magnetic oscillations in HgSe monocrystal with Co impurities of low concentration (&lt;1 at%)

The results of experimental studies of magnetoresistance oscillations are described for a HgSe monocrystal with Co impurities of low concentration (&lt;1 at%). It has been discovered that at such impurity concentrations (~10 18 cm -3 ) there exists two types of magnetic oscillations: Shubnikov de Haas oscillations at low temperatures (T&lt;10 K) and magnetophonon oscillations at higher temperatures (T&gt;10 K). The first ones are caused by the interaction of electrons with magnetic fieled inside of a Landau sublevel and the latter --- by the interaction with longitudinal optical phonons. The differences of these oscillations are characterized. A hypothesis of a nature of magnetophonon oscillations in such structures is proposed. Keywords: 3d-impurities of low concentration, zero-gap semiconductors, magnetophonon oscillations, SdH oscillations, optical and acoustic phonons.
Watchtower Selection in Off-Blockchain PCN Using Peterson Leader-Election Algorithm

Despite the incredible adoption of cryptocurrencies, blockchain-based cryptocurrencies have likewise raised some concerns. The scalability problem is the major one among them. An off-blockchain payment channel network (PCN) has been introduced to solve this issue. PCN can fundamentally reduce blockchain scalability by constructing a number of payment channels between the nodes and without committing every single transaction to the blockchain. But as a matter of fact, there has an unwanted assumption in PCN that channel participants must remain online and follow blockchain updates, for the synchronization with blockchain to protect the channel against deception. To mitigate this issue “Watchtower” concept has been proposed. Watchtower is a watching service and always stays online that a channel participant can hire it by offering incentives for monitoring the channel and checking blockchain updates consistently to prevent fraud on behalf of the hiring party. However, watchtower may be more beneficial by cooperating with the cheating counterparty and neglecting to perform the watching service properly. The efficiency drawback can occur for that. In this work, we have been motivated by this issue and tried to find out an effective and reliable watchtower for the channel watching service from multiple watchtower nodes or candidates in the PCN. In particular, we have been approached by using the distributed Peterson Leader-Election Algorithm to find the best watchtower among multiple of them where the more successfully performed work node or candidate will be selected for the channel monitoring job. We also have provided a detailed step-by-step process of the algorithm including experiments and illustrations for employing watchtower among multiple of them.

Validation of Global Solar Radiation Models on a Horizontal Surface in the Climatic Zones of Burkina

The evaluation of the solar deposit is essential for the sizing of photovoltaic systems. This requires the availability of radiation data. In Burkina Faso, weather data doesn’t cover all the country. That makes that solar radiation measured are not available for the all country. Theorical methods can help about it. This paper is written to fill the gap of adapted solar models for the country. In this work, an analysis of the results provided by four models for the estimation of hourly values ​​of global radiation on a horizontal plane was made. The radiation data for the year 2017 comes from the Burkina weather forecast. The validation of the models is carried out by a comparison between the radiation measured and that given by the various models provided by MATLAB code. The different models have been validated by several statistical indicators (RMSE and normalized MAE) and graphs for a clear sky. Scoring criteria have been established to assess the relative quality of each model. The models retained for the study are the Bird and Hulstrom model, the Davy and Hay model, the Capderou model and the Liu and Jordan model. Three sites were affected: Ouagadougou, Dori and Gaoua. We found that for some models, there is a good agreement between the measured values ​​and those estimated by some models for the Dori site, while they are not with the values ​​measured for the Ouagadougou and Gaoua sites. In the town of Dori, the most appropriate model for estimating solar radiation is that of Bird and Hulstrom. For the cities of Ouagadougou and Gaoua, the different models are not suitable.

"Using MongoDB to Understand the Underlying Methods Techniques Encryption in NoSQL database"

There is a need for appropriate encryption methods, which must be adhered by the concerned parties, in order to provide a high level of security for the secret data. In this study, an examination of the different encryption algorithms and their performance in the management of private data with authentication, access control, secure configuration, and data encryption is presented. It includes enhancing MongoDB's level-based access protected model and adding privacy keys for security and monitoring purposes respectively. The NoSQL data stores, also known as highly compressed data on non-relational database management systems, which provide support for data management of internet user programs, do not now offer this service. Data security, encryption techniques, MongoDB, and NoSQL are some of the keywords that come to mind.The proper encryption methods used to various crucial data fields provide data protection without adversely affecting the database's performance in terms of speed or memory usage. Due to the use of appropriate encryption techniques, this is achievable. Since document-oriented and unstructured data are generally kept in databases, it is frequently used to handle various sorts of data. Examples of such databases include MongoDB, Cassandra, CouchDB, Redis, Hyper-table, and others. Since they are open source, there is a critical necessity to offer good security and protect the user's private information when it is in transit or at rest. There is a need for a single solution that can improve the security of data transfer by providing an improved encryption method that speeds up processes and uses less memory when maintaining databases.
The Complexity of Counting Problems over Incomplete Databases

We study the complexity of various fundamental counting problems that arise in the context of incomplete databases, i.e., relational databases that can contain unknown values in the form of labeled nulls. Specifically, we assume that the domains of these unknown values are finite and, for a Boolean query $q$, we consider the following two problems: given as input an incomplete database $D$, (a) return the number of completions of $D$ that satisfy $q$; or (b) return the number of valuations of the nulls of $D$ yielding a completion that satisfies $q$. We obtain dichotomies between \#P-hardness and polynomial-time computability for these problems when $q$ is a self-join-free conjunctive query, and study the impact on the complexity of the following two restrictions: (1) every null occurs at most once in $D$ (what is called Codd tables); and (2) the domain of each null is the same. Roughly speaking, we show that counting completions is much harder than counting valuations: for instance, while the latter is always in \#P, we prove that the former is not in \#P under some widely believed theoretical complexity assumption. Moreover, we find that both (1) and (2) can reduce the complexity of our problems. We also study the approximability of these problems and show that, while counting valuations always has a fully polynomial-time randomized approximation scheme (FPRAS), in most cases counting completions does not. Finally, we consider more expressive query languages and situate our problems with respect to known complexity classes.
